Application example 1

The energy absorption device provided by the embodiment of the application can be applied to heating and is used as a microwave heating device.

Referring to fig. 1, a microwave heating apparatus according to an embodiment of the present application may include amicrowave transmission line 100 and a microwave feeding port (not shown). Themicrowave transmission line 100 includes atransmission conductor 10, anauxiliary medium 20, and a transmission ground disposed around thetransmission conductor 10 to form ashield case 40, and theauxiliary medium 20 and thetransmission conductor 10 are disposed in theshield case 40. Thetransmission conductor 10 comprises afirst end 11, thefirst end 11 of thetransmission conductor 10 penetrates the shieldingshell 40; the microwave feed port is connected with thefirst end 11.

The microwave feed-in port is used for accessing a microwave signal; theshield case 40 is used for placing theobject 30 to be heated; the microwave heating device is used to heat theobject 30 to be heated.

The transmission ground of themicrowave transmission line 100 forms a shieldingshell 40, and the microwave signal accessed by the microwave feed-in port enters the shieldingshell 40 and then is transmitted along thetransmission conductor 10, so that the shielding shell can reduce the microwave signal leakage outwards. In some embodiments, theshield shell 40 may be a fully enclosed shell or a semi-open shell. In some embodiments, thefirst end 11 of thetransmission conductor 10 penetrates the shieldingshell 40, and thefirst end 11 may be exposed to the outer surface of the shieldingshell 40, so that thefirst end 11 may be coupled with a microwave signal source. For example, thefirst end 11 may protrude from an outer surface of the shieldingshell 40, or thefirst end 11 may be flush with the shieldingshell 40. Theauxiliary medium 20 is used to fill theshield case 40 to form a microwave transmission line. The microwave signal is transmitted in themicrowave transmission line 100, theobject 30 to be heated is placed in the shieldingshell 40, theobject 30 to be heated can be regarded as a medium in the microwave transmission line, and the microwave energy is converted into heat energy to be consumed by theobject 30 to be heated and the auxiliary medium 20 in the transmission process, so that the microwave heating is realized.

Wherein theauxiliary medium 20 may comprise a dielectric and/or magnetic medium and thetransmission conductor 10 may comprise an electrical conductor, such as a metal. Theauxiliary medium 20 may also serve to isolate thetransfer conductor 10 from theobject 30 to be heated, to prevent thetransfer conductor 10 and theobject 30 to be heated from directly contacting, causing damage to thetransfer conductor 10, such as rusting, corrosion of thetransfer conductor 10, or leaving harmful substances on thetransfer conductor 10. In some embodiments, thesecondary media 20 may comprise one or more of air, plastic, PCB board, or ceramic.

Since the loss tangent of theobject 30 to be heated is larger than that of theauxiliary medium 20, energy is more lost to theobject 30 to be heated, which is highly lossy, and heating of theobject 30 to be heated is achieved.

Illustratively, the loss tangent of theauxiliary medium 20 is less than 0.02.

Further, by using the critical value of 0.02 rather than an excessively small loss tangent as the critical value, the degree of influence of theauxiliary medium 20 on the heating effect can be increased, and the adjustability of the heating effect can be improved.

Illustratively, the microwave transmission section may be formed by bending at a plurality of locations to form the sides of the columnar structure.

The transmission conductor comprises one or more bent or spiral shapes in the shielding shell, so that a transmission path can be increased in a limited space, and the heating speed and the heating effect are improved.

As an exemplary implementation manner, the shielding shell of the embodiment of the present application includes a cover body and a container cooperating with the cover body, and the first end penetrates through the cover body or the container. As shown in fig. 5, thetransmission conductor 10 may be linear. Thetransmission conductor 10 may be fixed above, below or at another position of theobject 30 to be heated.

Application example two

The energy absorption device provided by the embodiment of the application can also be used for generating gas-like substances and is used as a gas-like substance generation device. For example, during absorption of energy by a medium, a gas, a population of liquid particles suspended in a gas (e.g., a mist), or a population of solid particles suspended in a gas (e.g., a flue gas) is produced by various physical or chemical reactions.

As an exemplary implementation, fig. 7 shows a schematic structural diagram of a gas generating apparatus according to an embodiment of the present application. As shown in fig. 7, the gas generating apparatus includes amicrowave transmission line 100 and amicrowave feed port 200. Themicrowave transmission line 100 includes atransmission conductor 10, agas generating substrate 30, and a transmission ground. Arranged transmissively around thetransmission conductor 10 forms a shieldedhousing 40 in which thegas generating substrate 30 and thetransmission conductor 10 are arranged. Theshield case 40 is provided with a first throughhole 41. Thetransmission conductor 10 comprises a first end, which extends through the shielding housing. Themicrowave feed port 200 is connected to the first end. The microwave feed-in port is used for accessing microwave signals.

Themicrowave transmission line 100 forms a shieldingshell 40 in a transmission manner, and a microwave signal accessed from the microwave feed port enters the shieldingshell 40 and is transmitted along thetransmission conductor 10, so that the microwave energy is prevented from leaking. Thegas generating substrate 30 is disposed in the shieldingcase 40, and thegas generating substrate 30 may be regarded as a medium of a microwave transmission line, and microwave energy is absorbed and consumed by thegas generating substrate 30 during transmission to generate a gas, which may be emitted from the first throughhole 41 to the outside of the shieldingcase 40.

For example, as shown in fig. 7, a second throughhole 42 may be further disposed on the shielding shell, and a caliber of the first throughhole 41 and/or the second throughhole 42 is smaller than a wavelength of a microwave signal accessed by the microwave feed port. The first throughhole 41 may serve as an inlet for air to equalize the air pressure inside and outside the shield case. The aperture of the first throughhole 41 or the second throughhole 42 is smaller than the wavelength of the microwave signal, so that the loss of microwave energy can be avoided.

Illustratively, the first throughhole 42 is disposed opposite to thegas generating substrate 30 so as to directly flow out of the first throughhole 42 after the gas is generated, thereby improving the gas application efficiency.

As an exemplary embodiment, thetransmission conductor 10 further includes a second end disposed within the shieldingshell 40, and an open or short circuit arrangement between the second end and the shieldingshell 40. The open circuit may be such that the second end is not in direct contact with the shielding shell 40 (as shown in fig. 7) and the short circuit may be such that the second end is in direct contact with the shieldingshell 40. The second end may also extend through theshield housing 40.

By adopting the technical scheme, the shielding shell is formed in the transmission ground in the microwave transmission line, and the microwave signal energy transmitted by the microwave transmission line is absorbed and consumed by the matrix generated by the gas-like substance in the process of being transmitted along the transmission conductor in the shielding shell. Gaseous form thing produces the base member and passes through energy absorption and consumption, can the thermally equivalent and produce gaseous form thing, solves prior art and is heated through the joule effect and is heated the inequality and lead to gaseous form thing to produce the partial residual problem of base member.

In some embodiments, as shown in FIG. 8, the gas generant device further includes asecondary media 20, wherein thesecondary media 20 may include dielectric and/or magnetic media. Theauxiliary medium 20 is disposed inside the shield case. Theauxiliary medium 20 may also serve as a transmission medium for the microwave transmission line. Theauxiliary medium 20 may be used to fill theshield case 40. As shown in fig. 8, an auxiliary medium may also be used to isolate thetransmission conductor 10 from thegas generating substrate 30. The transmission conductor is prevented from being rusted or harmful substances are left on thetransmission conductor 10.

As an exemplary embodiment, thegas generating substrate 30 has a loss tangent greater than that of theauxiliary medium 20. Since the loss tangent of thegas generating substrate 30 is larger than that of theauxiliary medium 20, more energy is consumed by thegas generating substrate 30 having high energy consumption, and the energy is mainly used for generating the gas, thereby improving the energy use efficiency.

Illustratively, the loss tangent of theauxiliary medium 20 is less than 0.02. The loss tangent of theauxiliary medium 20 is less than 0.02, which ensures that the loss tangent of theauxiliary medium 20 is less than that of most gaseous generating substrates. Furthermore, by using the critical value of 0.02 rather than an excessively small loss tangent as the critical value, the degree of influence of theauxiliary medium 20 on the energy consumption effect can be increased, the adjustability of the energy distribution can be improved, and it is convenient to set different operation modes for the gas generating apparatus.

Illustratively, theauxiliary medium 20 is ceramic. Ceramics have a low loss tangent and are suitable as insulating materials.

As an exemplary embodiment, the solid auxiliary medium 20 may be provided with a placing portion for placing the gas generating substrate.

As an exemplary embodiment, theshield case 40 may be provided with an opening for taking and placing the gas generating substrate. The gas-like substance generating base body can be replaced, and the integral waste of the gas-like substance generating device after the gas-like substance generating base body is consumed is avoided.

In some embodiments, as shown in fig. 9, the aerosol-generatingsubstrate 30 may extend through theshield shell 40, being divided into a first substrate portion and a second substrate portion, the first substrate portion being inside theshield shell 40 and a portion being outside theshield shell 40.

In any of the above embodiments, thetransmission conductor 10 may be linear.

In some embodiments, thetransmission conductor 10 may also include a microwave transmission section. The microwave transmission section is arranged in the shielding shell, and the microwave transmission end can be in a spiral spring shape and a bending line shape, or can be bent at multiple positions to form a fishfork shape or a hollow column shape. The transmission conductor comprises one or more bent or spiral shapes in the shielding shell, so that a transmission path can be increased in a limited space, and the heating speed and the heating effect of the gas-like substance generating matrix are improved. For example, the microwave transmission section of the transmission conductor surrounds a columnar structure having an internal cavity. The microwave transmission section may form the columnar structure around a central axis, and the inner cavity may contain an object to be heated or an auxiliary medium. Illustratively, the microwave transmission section may be formed by bending at a plurality of locations to form the sides of the columnar structure.

As an exemplary embodiment, as shown in fig. 10 and fig. 11, the first throughhole 41 and/or the second throughhole 42 may include a plurality of small circular holes having a radius much smaller than a wavelength of a microwave, which effectively prevents electromagnetic leakage.

The gas generating device of the embodiment of the application can be applied in various forms:

for example, the vapor-generating device may be an electric mosquito coil, wherein the vapor-generating substrate may be a mosquito mat or a mosquito coil liquid. For example, the mosquito-repellent incense piece is wholly arranged in the shielding shell, and the mosquito-repellent incense piece is stored, taken and replaced through the opening arranged on the shielding shell. The mosquito-repellent incense piece is used as a medium of a microwave transmission line, absorbs and consumes microwave energy to generate mosquito-repellent gas.

In the shielding shell of the electronic cigarette, the transmission conductor and the electronic cigarette oil are isolated by using a solid auxiliary medium, and the electronic cigarette oil can completely fill or partially fill the shielding shell.

Application example three

The energy absorption device provided by the embodiment of the application can also be used as a non-combustion smoking set.

As an exemplary implementation, fig. 14 shows a schematic structural view of a non-combustion smoking article according to an embodiment of the present application. The non-burning smoking article is used to heat thesmoking article substrate 30 to be heated. The form of thesmoking article substrate 30 to be heated may include a solid or liquid form. Such as tobacco or tobacco tar. As shown in fig. 14, the non-combustion smoking article includes atransmission conductor 10, a transmission ground, and a microwave feed port. Disposed transmissively around thetransmission conductor 10 forms a shieldedcavity 40, with thetransmission conductor 10 disposed within the shieldedcavity 40. Thesmoking article substrate 30 to be heated can be placed in the shieldingcavity 40, and thesmoking article substrate 30 to be heated can be regarded as a medium in a microwave transmission line, and forms the microwave transmission line together with thetransmission conductor 10 and the shieldingcavity 40. Theshield cavity 40 is provided with ashield cover 50. When the shieldingcover 50 is opened, thetobacco base 30 to be heated can be put into the shieldingcavity 40 or the inner chamber of the shieldingcavity 40 can be cleaned. When the shieldingcover 50 is closed, a sealed chamber is formed with the shieldingcavity 40 to prevent leakage of microwave energy. One or more shield covers 50 may be provided.

Thetransmission conductor 10 penetrates through the shieldingcavity 40 and is connected with the microwave feed-in port. The microwave feed-in port is used for accessing microwave signals. In some embodiments, the end surface of thetransmission conductor 10 penetrating the shieldingcavity 40 may be exposed to the outer surface of the shieldingcavity 40, and coupled to the microwave signal source. Illustratively, the port may be a portion that protrudes from an outer surface of the shieldedcavity 40 or may be flush with the shieldedcavity 40. The energy of the microwave signal is absorbed and consumed by thesmoking article substrate 30 to be heated during the transmission of the energy in the transmission line, so that microwave heating is realized and smoke is generated.

In some embodiments, as shown in fig. 15, the non-combustion smoking article may further comprise asecondary media 20. Theauxiliary medium 20 is disposed in the shieldingcavity 40 and is used for isolating thetransmission conductor 10 from thesmoking article substrate 30 to be heated so as to prevent thetransmission conductor 10 and thesmoking article substrate 30 to be heated from being in direct contact and causing damage to thetransmission conductor 10.

Further, by using the critical value of 0.02 rather than an excessively small loss tangent as the critical value, the degree of influence of theauxiliary medium 20 on the heating effect can be increased, and the adjustability of the heating effect can be improved.

Theauxiliary medium 20 may be air or ceramic, for example. Air or ceramic is a common object with a small loss tangent, so that the heating effect is ensured, and meanwhile, the cost and the realization difficulty of the microwave heating device are reduced.

As shown in fig. 23, the process of controlling the output frequency of the microwave generator provided in this embodiment may include steps S110, S120, and S210 as follows:

and S110, setting the output frequency of the microwave generator according to the set frequency interval in the set frequency range. For example, the set frequency range may be 300Hz to 400Hz, the frequency interval is 10Hz, the microwave generator may increase the frequency value from 300Hz every 10Hz, so that the microwave generator outputs microwave signals with frequencies of 300Hz, 310Hz, 320Hz, 330Hz, …, and 400 Hz. The microwave transmission line continuously generates loss under the excitation of microwave signals, and the effect of uniform heating is achieved.

And S120, acquiring the working state of microwave heating under each output frequency.

S210, determining the output frequency of the microwave generator according to the working state of each output frequency.

In the embodiment of the application, when the microwave generator outputs the microwave signals of corresponding frequencies step by step according to a certain frequency interval, the feedback power of the microwave transmission quantity under each output frequency can be obtained, and the range or a certain numerical value of the output frequency of the microwave generator can be determined according to the change condition of the feedback power, so that the energy fed in by the microwave generator can be ensured to achieve better utilization efficiency.

In some embodiments, the temperature change of the object to be heated and the change of the substance generated by the object to be heated at each output frequency can be obtained to determine the range or a certain value of the output frequency of the microwave generator, and the feeding capacity of the microwave generator can be ensured to achieve better utilization efficiency.

In some embodiments, during the microwave heating by the step-by-step setting of the microwave generator, whether or not the object to be heated is present in the microwave transmission line may be judged by the change in the reflected power.

Exemplarily, referring to fig. 24, fig. 24 shows a control process of whether the output of the microwave generator is or is not, including steps S410 to S440, as follows:

and S410, acquiring the reflected power of the microwave transmission line for microwave heating at each output frequency.

And S420, judging whether the reflected power is smaller than a first reflected power threshold value.

And S430, if the reflected power is larger than the first reflected power threshold value, the output of the microwave generator is turned off.

S440, if the reflected power is less than the first reflected power threshold, maintaining the output of the microwave generator.

In the embodiment of the present application, the first reflected power threshold value is used for determining whether or not an object to be heated is present. The value range is related to the loss tangent of the object to be heated and the transmission line in contact with the object to be heated. The smaller the loss tangent, the greater the power reflected, while the larger the loss angle of the object to be heated, the smaller the power reflected. Therefore, the present embodiment may set one reflected power threshold, i.e., the first reflected power threshold. If the reflected power is greater than the first reflected power threshold, indicating the absence of an object to be heated, the output of the microwave generator may be turned off.

Typically, the first reflected power threshold is less than the rated output power of the microwave generator. For example, the nominal output power is 40dBm, and the first reflected power threshold may be set to 34dBm or less.

In general, the first reflected power threshold value may be determined according to a loss tangent between a loss tangent of a body to be heated and a loss tangent of a transmission line in contact with the body to be heated. For example, when the object to be heated is not added to the microwave transmission line, the reflected power is 36 dBm; adding an object to be heated into the microwave transmission line, wherein the reflected power is 20 dBm; at this time, the value of the first reflected power threshold may be 20-36 dBm.

In some embodiments, if the reflected power is less than the first reflected power threshold, indicating the presence of an object to be heated, the output of the microwave generator may be maintained. Meanwhile, the output frequency of the microwave generator can be adjusted, and the energy consumption ratio of microwave heating is improved. The output frequency of the microwave generator may be specifically adjusted as follows:

first, the reflected power within the set range is selected from the acquired reflected powers. The setting range may be a range in which one or more reflected powers at the respective arrangement positions are sequentially selected, for example, a minimum reflected power. The setting range may be a range having an upper limit value and a lower limit value.

Then, whether the reflected power within the set range is smaller than a second reflected power threshold value is judged. For example, it is determined whether the minimum reflected power is less than a second reflected power threshold.

At this time, if the reflected power within the set range is less than the second reflected power threshold value, the output frequency of the microwave generator is set according to the output frequency corresponding to the reflected power within the set range. For example, an output frequency corresponding to the minimum reflected power can be selected from this set range as the output power of the microwave generator.

In addition, if the reflected power within the set range is greater than the second reflected power threshold, the frequency interval is narrowed. And continuously setting the output frequency of the microwave generator at the frequency interval, acquiring corresponding reflected power, and repeating the steps until the reflected power within the set range is smaller than a second reflected power threshold value.

In some embodiments, the frequency range in which the microwave generator operates may be determined during the step-wise setting of the microwave generator for microwave heating.

Exemplarily, referring to fig. 25, fig. 25 shows a control process of a range of an output frequency of a microwave generator, including steps S510 to S530, as follows:

and S510, acquiring the reflected power of the microwave transmission line for microwave heating at each output frequency.

S520, a range of the output frequency of the microwave generator is determined in a case where the reflected power of the microwave transmission line is lower than a second reflected power threshold. Generally, the second reflected power threshold is lower than the first reflected power threshold.

S530, keeping the output frequency of the microwave generator within the range of the determined output frequency.

In this embodiment, the second reflected power threshold is used to determine the working state of the power source, and the output frequency smaller than the second reflected power threshold is beneficial to feeding microwave energy, i.e. effective heating can be achieved. And taking the second reflected power threshold as a boundary, and taking the output frequency corresponding to the reflected power smaller than the second reflected power threshold as a working frequency point of the microwave generator. Of course, the smaller the reflected power, the more favorable the output frequency corresponds to for the energy feed, i.e. heating, of the microwave signal. The value of the second reflected power threshold is within a certain range, and the value range is related to the rated output power of the microwave generator. For example, when the rated output power is 40dBm, the second reflected power threshold may be set to 30dBm or lower.

During the microwave heating process, the reflected power of the microwave transmission line may shift in frequency. For example, the output power F and the operating frequency point of the microwave transmission line are F, and at time t1, the reflected power of the microwave transmission line is less than the second reflected power threshold, but at time t2, the reflected power of the microwave transmission line may be at the second reflected power threshold. However, we need to ensure that the microwave generator remains in operation at all times when the reflected power is lower than the second reflected power. This requires that the embodiment of the present application automatically track the output power, and operate with the minimum output power when the reflected power is lower than the second reflected power threshold, so as to achieve the purpose of optimization.

Illustratively, 3 output powers are generated in steps of 1MHz, based on the current output power f, for example: f-2, f-1, f; alternatively, f-1, f, f + 1; or f, f +1,f + 2. Then, the microwave generator outputs corresponding microwave signals to the microwave transmission line in sequence according to the generated output power, and obtains the reflected power fed back under each output power. And selecting the output power corresponding to the minimum reflected power as the output power of the current microwave generator. After the microwave generator was operated at the above selected output power for 2 seconds, the above operation was repeated again. It should be noted that the above-mentioned step is not limited to 1MHz, and may be 2MHz, 3MHz, or the like. The duration of the operation is not limited to 2 seconds, and may be 4 seconds, 5 seconds, or the like. This is done for convenience of example only.

In some embodiments, the operation state includes at least one of a gas generation amount of the object to be heated, a temperature of the microwave transmission line, and a time period of the microwave heating, and the determining includes:

judging whether the working state reaches a threshold value corresponding to the working state;

and if the working state reaches the threshold value corresponding to the working state, determining the output waveform of the microwave generator.

Illustratively, the output waveform of the microwave generator may be dynamically adjusted if the time period for heating the object to be heated reaches a preset time period threshold value. Alternatively, the gain or gate voltage of the microwave power amplifier may be adjusted so that the output power of the microwave signal input into the microwave transmission line can meet the heating requirement. The output waveform of microwave generation may also be adjusted at this time if the gas generation amount of the object to be heated reaches a preset gas content threshold value. For example, a continuous wave microwave signal is adjusted to a pulsed microwave signal. For another example, the duty cycle of the pulsed microwave signal is adjusted. Alternatively, if the temperature of the object to be heated reaches a preset temperature threshold value, the output waveform of the microwave generator may be adjusted. Or, if the temperature of the microwave transmission line reaches a preset temperature threshold value, the output wave device of the microwave generator can be adjusted.

In some embodiments, the microwave generator may include multiple microwave output ports. The microwave transmission line may include a plurality of microwave feed ports, each microwave feed port being connected to a microwave output port for receiving the plurality of microwave signals. The operating state may include the properties of the object to be heated and the positional relationship between each microwave feed port and the object to be heated. The attribute of the object to be heated may include the shape, size, type, and the like of the object to be heated. The positional relationship may include a distance, an angle, and the like. When the microwave signals are transmitted to the object to be heated, the microwave signals can be synthesized into one microwave signal so as to improve the feeding efficiency of microwave energy.

Exemplarily, the step S200 may include: and determining the output phase of each microwave signal fed into each microwave feed-in port by the microwave generator according to the attribute of the object to be heated and the position relationship between each microwave feed-in port and the object to be heated. For example, assuming that there are four microwave feed ports, the output phases of the microwave signals fed to the microwave feed ports are determined to be 15 degrees, 45 degrees, 75 degrees, and 90 degrees, respectively, based on the positional relationship between the microwave feed ports and the object to be heated, and the shape of the object to be heated. When the microwave signals of different phases are transmitted to the object to be heated, one microwave signal can be synthesized to heat the object to be heated.

Referring to fig. 26, fig. 26 shows a structure of a microwave heating apparatus provided in an embodiment of the present application. The microwave heating apparatus includes amicrowave generator 1, amicrowave power amplifier 2, acontrol unit 4, and amicrowave transmission line 3. Themicrowave transmission line 3 comprises a shielded cavity in which theobject 6 to be heated can be placed and which constitutes a part of themicrowave transmission line 3. Theobject 6 to be heated may include a solid substance or a liquid substance, for example, tobacco tar, aroma, and the like. The microwave output port of the microwave generator is connected with the microwave feed-in port of the microwave transmission line. The microwave output port and the microwave feed port may employ a standard 50 Ω impedance or a non-standard impedance.

Thecontrol unit 4 controls themicrowave generator 1 to generate a microwave signal, themicrowave generator 1 transmits the generated microwave signal to themicrowave power amplifier 2, themicrowave power amplifier 2 amplifies the received microwave signal and feeds the amplified microwave signal into themicrowave transmission line 3, and themicrowave transmission line 3 is excited by the microwave signal to generate heat through self-loss, so that theobject 6 to be heated is heated. Meanwhile, thecontrol unit 4 acquires the state of theobject 6 to be heated or the state of themicrowave transmission line 3, and adaptively adjusts the working parameters of themicrowave generator 1 or themicrowave power amplifier 2 according to the acquired state, so that the power of the microwave signal fed into themicrowave transmission line 3 meets the heating requirement. For example, if theobject 6 to be heated is a gas matrix, the demand for the amount of mist that can be generated by heating needs to be satisfied.

Illustratively, thecontrol unit 4 monitors the temperature of themicrowave transmission line 3 in real time. When the temperature of themicrowave transmission line 3 reaches a predetermined value, thecontrol unit 4 starts the corresponding operation. For example, the output waveform of themicrowave generator 1 is changed, the gain of themicrowave power amplifier 2 is changed, and the like. It is ensured that themicrowave transmission line 3 is not inconvenient to use or even damaged due to an excessively high temperature.

Illustratively, thecontrol unit 4 monitors the reflected power of themicrowave transmission line 3 in real time, directly or indirectly determining the conditions of the on or off operation of themicrowave generator 1 and themicrowave power amplifier 2, the output frequency range of the energy feed-in, etc.

Themicrowave transmission line 3 is pure for continuously heating the gas-like substance matrix, and when a certain temperature interval is reached, for example: the aerosol amount reaches an excellent state at 280 +/-5 ℃. At this time, thecontrol unit 4 can adaptively adjust the operating parameters of themicrowave generator 1 and the microwave power amplification so that the temperature of the gas substrate tends to be constant and the aerosol generation amount is maintained in an excellent state.

Based on the above embodiments, the flow of the adaptive control of the output frequency in the embodiments of the present application may be as follows:

in the first step, microwave feed-in and microwave generator turn-on or turn-off are judged step by step. The microwave generator feeds microwaves into the microwave transmission line in a set frequency step, and the control unit detects the reflected power fed back to the microwave generator by the microwave transmission line in the feeding process. The control unit judges whether the reflected power is less than a first reflected power threshold. If the reflected power is less than the first reflected power threshold, the output of the microwave generator is maintained. If the reflected power is greater than the first reflected power threshold, it is an indication that the object to be heated is not present, at which point the output of the microwave generator needs to be turned off.

In a second step, the range of the output frequency of the microwave generator is determined. The control unit compares the reflected power corresponding to each output power, and determines the range of the output power corresponding to the reflected power smaller than the second reflected power threshold value. And the output power of the microwave signal output from the microwave generator is controlled to fall within the range of the output power determined here.
