The flange portion 422 is formed with at least one air intake hole 4221 to allow outside air to enter the receiving cavity 410. The at least one air inlet hole 4221 is formed on the flange portion 422 and can be formed by inward recessing of the outer edge of the flange portion 422, so that special holes on the housing 41 can be avoided, the processing technology can be saved, and the aesthetic property and the integrity of the product appearance can be ensured. At least one air guide groove 4211 is formed on the outer wall surface of the body 421, and the at least one air guide groove 4211 is provided corresponding to the at least one air intake hole 4221. The at least one air guide groove 4211 extends downward from the upper end surface of the body portion 421, thereby communicating the air intake hole 4221 with the receiving cavity 410.

The connection head 42 and the first electrode post 43 are electrically connected to the negative electrode and the positive electrode (or the positive electrode and the negative electrode) of the battery device 45, respectively.
As shown in fig. 5-9, the atomizer 1 may in some embodiments include a base assembly 10 for detachable connection with the host 4, an atomizer body 20 mounted longitudinally on an upper end of the base assembly 10, and a suction nozzle assembly 30 mounted longitudinally on an upper end of the atomizer body 20.

The base assembly 10 may in some embodiments include a conductive base 11, a second electrode post 12 disposed longitudinally insulated in the base 11, and an induction conduit 13 extending longitudinally through an upper end of the second electrode post 12. The base 11 is used for connecting with and contacting with the connector 42 of the host 4, and the base 11 may be made of metal, such as stainless steel, preferably 316 medical grade stainless steel containing no heavy metal.

The through-holes 2510 form an atomization chamber for mixing mist and air generated by the atomization assembly 25. The main body 2511 may be substantially rectangular and elongated, and the two engaging arms 2512 are respectively disposed on two opposite sides of the upper end of the main body 2511 in the longitudinal direction. The extension 2513 may have a cylindrical shape, and the extension 2513 may increase the axial length of the through hole 2510, increasing the installation space of the heating element.
A liquid storage cavity 210 for storing liquid matrix is defined between the inner wall surface of the shell 21 and the outer wall surface of the outer tube 22, and at least one liquid inlet 2210 is arranged on the outer tube 22 so that the liquid matrix in the liquid storage cavity 210 can enter the outer tube 22 through the at least one liquid inlet 2210, and the liquid suction 251 is connected with the liquid storage cavity 210 in a liquid guide way.

The body portion 2511 of the suction body 251 and the two engagement arms 2512 are provided in the first tube section 221, and the extension portion 2513 extends upward from the top surface of the body portion 2511 and into the second tube section 222. Two liquid inlets 2210 are formed on two sides of the top wall of the first pipe section 221, and the two liquid inlets 2210 are respectively corresponding to two clamping arms 2512 of the liquid absorbing body 251. The side and end surfaces of the clamping arm 2512 absorb liquid, and the main body 2511, the extension portion 2513 and the outer tube 22 are connected in a sealing mode, so that the liquid absorbing body can block the liquid matrix, and good liquid guiding effect can be guaranteed. In some embodiments, the distance between the end surfaces of the two clamping arms 2512 is smaller than the inner diameter of the first pipe section 221, so that a gap is formed between the two clamping arms 2512 and the first pipe section 221, which is beneficial to liquid discharging and liquid sucking, and can prevent the liquid sucking 251 from contacting the outer pipe 22 to conduct heat directly.

By arranging the induction pipe 13 in the inner pipe 27, the inherent space in the structure is fully utilized, the design difficulty of the induction air passage can be reduced, the space is saved, and the cost is reduced.

In the present embodiment, four reinforcing holes 321 are provided on the cylindrical side wall of the fastener 32 at regular intervals in the circumferential direction. The inner diameter of the fastener 32 is adapted to the outer diameter of the third tube section 223 of the outer tube 22 to provide a stronger connection with the top of the third tube section 223 in an interference fit with the fastener 32. The top of the third tube segment 223 may rest against the bore bottom surface of the second stepped bore 3102.
The third pipe section 223 is in sealing engagement with the wall of the third stepped bore 3103, typically by providing a sealing ring 33 between the outer side wall of the third pipe section 223 and the wall of the third stepped bore 3103. The seal ring 33 may be made of flexible material, such as silica gel, in some embodiments, to facilitate sealing effect. At least one blocking wall 2231 may be formed on the outer sidewall of the third tube segment 223 for press-fit positioning of the sealing ring 33. In the present embodiment, the upper end of the third pipe section 223 is stretched to form two annular blocking walls 2231, the blocking walls 2231 are distributed at intervals along the axial direction of the third pipe section 223, and the upper and lower sides of the sealing ring 33 respectively abut against the two blocking walls 2231.
When the electronic atomizing device works, a user inhales from the suction nozzle part 313 of the suction nozzle 31, negative pressure generated by inhalation is transmitted to the air switch induction air passage through the air outlet passage of the mist conveying passage, the air switch 46 is started, the power supply device 45 supplies power to the atomizing assembly 25, and the atomization of the liquid matrix is started. At the same time, the external air enters the atomizing cavity through the air inlet channel of the mist conveying channel and is mixed with the mist. The mixture of mist and air then enters the mouth of the user through the air outlet channel of the mist conveying channel.
It is to be understood that the foregoing examples merely illustrate preferred embodiments of the present invention, and are not to be construed as limiting the scope of the invention, but that it is to be understood that modifications and improvements to the above-described embodiments may be made by those skilled in the art without departing from the spirit of the invention, and that it is intended to cover all modifications and improvements as fall within the scope of the invention.
