背景技术Background technique
对于睡眠呼吸暂停症患者（即打鼾严重的患者），在睡眠中呼吸停止持续的时间过长，会造成血液中的氧气减少，机体处于缺氧状态。呼吸暂停会使得患者睡眠变得很浅并且支离破碎，患者得不到优质睡眠。即使睡足十小时也不能充分休息从而导致日间精神不足及其它严重不良后果。如果这种呼吸暂停频繁发生，经积年累月会给机体带来一系列严重的生理病理。For patients with sleep apnea (that is, patients with severe snoring), prolonged breathing stops during sleep will cause the oxygen in the blood to decrease, and the body is in a state of hypoxia. Apnea can make the patient's sleep very shallow and fragmented, and the patient cannot get quality sleep. Even if you sleep for ten hours, you can't get enough rest, which will lead to lack of energy during the day and other serious adverse consequences. If this apnea occurs frequently, it will bring a series of serious physiological pathologies to the body over time.
在现有技术中，通常使用呼吸机来治疗这种睡眠呼吸暂停症。虽然有些呼吸机包括有加湿器，但是这种加湿器水箱的加热区和储水区的水并不隔开，导致加热时，在对加热区内的水加热时同时也对储水区内的水极爱热，从而加热速度慢，患者对这些呼吸机的体验反馈并不好。In the prior art, this type of sleep apnea is usually treated with a ventilator. Although some ventilators include humidifiers, the water in the heating area and the water storage area of the humidifier water tank are not separated, causing the water in the heating area to be heated while heating the water in the water storage area. Water loves heat so much that it heats up slowly, and patient feedback on these ventilators has not been good.
发明内容Contents of the invention
针对上述问题，本发明提出了一种用于呼吸机的加湿器。本发明还涉及包含这种加湿器的呼吸机。根据本发明的呼吸机能够给患者带来具有适当温度和湿度的空气。In view of the above problems, the present invention proposes a humidifier for a ventilator. The invention also relates to a ventilator comprising such a humidifier. The ventilator according to the present invention is able to bring air with proper temperature and humidity to the patient.
根据本发明的第一方面，提出了一种用于呼吸机的加湿器，包括由主体和底板围成的水容纳腔，水容纳腔通过竖直设置在其中的隔板分隔成密闭的储液腔和与外界连通的加热腔，在底板上设置有仅加热加热腔内的水以蒸出湿润空气的加热装置，其中，在隔板上设有通道，通道设置成邻近于底板并将储液腔和加热腔连通，使得储液腔内的水能补充到加热腔内。According to a first aspect of the present invention, a humidifier for a ventilator is proposed, comprising a water holding chamber surrounded by a main body and a bottom plate, the water holding chamber is divided into a closed liquid storage chamber by a partition vertically arranged therein The chamber and the heating chamber communicated with the outside world are provided with a heating device on the bottom plate that only heats the water in the heating chamber to evaporate the humid air, wherein a channel is provided on the partition plate, and the channel is arranged adjacent to the bottom plate and stores the liquid The chamber communicates with the heating chamber so that the water in the liquid storage chamber can be replenished into the heating chamber.
根据本发明的加湿器，加热装置能够将加热腔内的水加热并蒸发出来，从而能够给患者提供温度和湿度适宜的空气。更重要地是，加热装置仅对加热腔内的水加热，加热腔内水温能快速升高到导致水快速蒸发，进而达到快速加湿空气的目的。另外，由于通道邻近于底板，一旦加热腔内的水位高于通道就会实现水封，储液腔内的水就不再流出，直到加热腔内的水被蒸发而使通道与空气再次连通为止。这实现了将加热腔内的水量自动地控制为很少，方便了使用。用语“密封的储液腔”是指储液腔不直接与外界连通，而是借助于通道通过加热腔与外界连通。According to the humidifier of the present invention, the heating device can heat and evaporate the water in the heating chamber, thereby providing air with suitable temperature and humidity for the patient. More importantly, the heating device only heats the water in the heating chamber, and the temperature of the water in the heating chamber can quickly rise to cause the water to evaporate quickly, thereby achieving the purpose of quickly humidifying the air. In addition, since the channel is adjacent to the bottom plate, once the water level in the heating chamber is higher than the channel, the water seal will be realized, and the water in the liquid storage chamber will no longer flow out until the water in the heating chamber is evaporated to make the channel communicate with the air again. . This realizes that the water quantity in the heating chamber is automatically controlled to be small, which is convenient for use. The term "sealed liquid storage chamber" means that the liquid storage chamber does not directly communicate with the outside world, but communicates with the outside world through the heating chamber by means of channels.
在一个实施例中，通道的高度上限到加热装置的距离在0.01mm-20mm之间。这样，通道非常接近于底板。由于通道用于将储液腔与外界大气连通，因此实际上保证加热腔内的液位非常低。这有助于提高加热腔内的水的加热速度。加热板仅对加热腔内的水加热，加热腔内水温能快速升高到导致水快速蒸发，进而达到快速加湿空气的目的。In one embodiment, the distance between the upper limit of the height of the channel and the heating device is between 0.01mm-20mm. In this way, the channel is very close to the floor. Since the channel is used to communicate the liquid storage chamber with the outside atmosphere, it is practically guaranteed that the liquid level in the heating chamber is very low. This helps to increase the heating rate of the water in the heating chamber. The heating plate only heats the water in the heating chamber, and the temperature of the water in the heating chamber can quickly rise to cause the water to evaporate quickly, thereby achieving the purpose of quickly humidifying the air.
在一个实施例中，储液腔包围在加热腔的外侧周围。这样，加热腔内的热量会向外扩散而加热储液腔内的水，避免了热量毫无用途的向环境中散失，提高了热量的利用率，并且进一步提高了加热腔内的水的加热速度。In one embodiment, the liquid storage chamber surrounds the outside of the heating chamber. In this way, the heat in the heating chamber will spread outward to heat the water in the liquid storage chamber, avoiding the useless loss of heat to the environment, improving the utilization rate of heat, and further improving the heating of the water in the heating chamber speed.
在一个实施例中，通道的过流面积与加热腔的底面积的比值为0.01-0.3。根据这种结构，储液腔内的水会缓慢进入到加热腔内，使得加热腔内的水温比较稳定，从而加热腔内的水蒸发速度恒定，空气的湿度也就保持为恒定，提高了患者的体验效果。In one embodiment, the ratio of the flow area of the channel to the bottom area of the heating chamber is 0.01-0.3. According to this structure, the water in the liquid storage chamber will slowly enter the heating chamber, so that the temperature of the water in the heating chamber is relatively stable, so that the evaporation rate of the water in the heating chamber is constant, and the humidity of the air is kept constant, which improves the patient's experience effect.
在一个实施例中，隔板与底板密封式相连并且包围加热装置，通道构造为在隔板的下部区域的将储液腔和加热腔连通的过流孔。这种设置的通道结构简单，易于制造和装配。In one embodiment, the partition is connected to the bottom plate in a sealed manner and surrounds the heating device, and the channel is configured as a flow hole in the lower region of the partition that communicates the liquid storage chamber with the heating chamber. The channel provided in this way has a simple structure and is easy to manufacture and assemble.
在一个实施例中，围绕加热装置设置有凸起的台阶，贯穿台阶而设置的凹槽形成通道，隔板与台阶的除凹槽以外的部分密封式相连。在一个具体实施例中，凹槽为矩形，并且矩形的长度与台阶周长的比值为0.05-0.5。台阶设置在加热装置的边缘处。这种结构的凹槽能将储液腔内的水完全放空，有利于提高加湿器的卫生状况。In one embodiment, a raised step is provided around the heating device, a groove formed through the step forms a channel, and the partition is connected in a sealing manner to the part of the step except the groove. In a specific embodiment, the groove is rectangular, and the ratio of the length of the rectangle to the circumference of the step is 0.05-0.5. The steps are provided at the edge of the heating device. The groove of this structure can completely empty the water in the liquid storage chamber, which is beneficial to improve the hygienic condition of the humidifier.
在一个实施例中，还包括设置在加热腔内的从主体的顶壁朝向加热装置延伸的挡板，挡板高于加热腔内的液面，从而将加热腔隔开成进气口和出气口。这种结构比较紧凑，有助于将加湿器的体积制造为较小。In one embodiment, it further includes a baffle arranged in the heating chamber and extending from the top wall of the main body toward the heating device, the baffle is higher than the liquid level in the heating chamber, thereby separating the heating chamber into an air inlet and an outlet. breath. This structure is relatively compact, which helps to make the volume of the humidifier smaller.
在一个实施例中，在进气口中设置有由在进气口内平行于气流方向设置的引导板而构成的消音装置。引导板能够将气体的流动理顺，从而避免了风吹动时发出噪音的问题。In one embodiment, a sound dampening device composed of guide plates arranged in the air inlet parallel to the airflow direction is provided in the air inlet. The guide plate can straighten the flow of gas, thus avoiding the problem of noise when the wind blows.
在一个实施例中，在底板的处于储液腔区域的部分上设置有加水孔。In one embodiment, a water filling hole is provided on the bottom plate in the area of the liquid storage chamber.
在一个实施例中，平面状导热板并且导热板的形状与加热腔的形状相一致。平面状加热装置有助于将加湿器制造为体积较小，方便了使用。In one embodiment, the heat conducting plate is planar and the shape of the heat conducting plate is consistent with the shape of the heating cavity. The planar heating device helps to make the humidifier smaller, which facilitates its use.
在一个实施例中，加湿器还包括容纳液体容纳腔的壳体，在壳体上设置有与进气口连通的进风口和与出气口连通的出雾口。In one embodiment, the humidifier further includes a housing containing the liquid containing chamber, and an air inlet communicating with the air inlet and a mist outlet communicating with the air outlet are arranged on the housing.
根据本发明的第二方面，提出了一种呼吸机，其包括用于吹风的主机，和与主机相连的根据上文所述的加湿器，其中加湿器的进气口与主机相连通以将风导入加湿器中。According to a second aspect of the present invention, a ventilator is proposed, which includes a host for blowing air, and a humidifier as described above connected to the host, wherein the air inlet of the humidifier communicates with the host to Air is introduced into the humidifier.
在本申请中，用语“竖直”是指与底板大体垂直的方面。In the present application, the term "vertical" refers to an aspect generally perpendicular to the base plate.
与现有技术相比，本发明的优点在于：（1）本发明发的用于呼吸机的加湿器能够给患者提供温度和湿度适宜的空气，从而使患者的体验效果更好。（2）加湿器的加热腔内的水量小于储液腔内的水量，并且加热装置仅加热加热腔内的水，从而加热腔内的水能快速升高到所要求的温度导致水快速蒸发，进而达到快速加湿空气的目的。（3）储液腔包围在加热腔的外侧周围。加热腔内的热量会向外扩散而加热储液腔内的水，避免了热量毫无用途的向环境中散失，提高了热量的利用率，并且进一步提高了加热腔内的水的加热速度。Compared with the prior art, the present invention has the following advantages: (1) The humidifier for ventilator of the present invention can provide patients with air with suitable temperature and humidity, so that the patient experience is better.

As shown in FIG. 2 , the humidifier 20 includes a water containing chamber 30 and a housing 22 containing the water containing chamber 30 . The air outlet 38 of the water holding chamber 30 is in sealing fit with the corresponding area of the cover 23 to ensure that there is no air leakage at the mist outlet 21 . In one instance, the housing 22 can be configured such that the upper lid 23 can be opened to remove the water holding chamber 30 therefrom. Also according to FIG. 3 , the housing 22 is provided with an air inlet (not shown) communicating with the air inlet 37 of the water storage chamber 30 and a mist outlet 21 communicating with the air outlet 38 of the water storage chamber 30 . The air inlet is connected with the air pipe 12 to lead the pressurized air from the host 11 into the humidifier 20 .
图3示意性地显示了水容纳腔30内部结构。水容纳腔30由主体31和底板32密封而成。底板32与主体31铰接以便于能够随时打开底板32而清洁水容纳腔30的内部。应理解地是，底板32也可以构造为能从主体31上完全拆下来。例如，可在底板32的边缘设置多个卡扣，在主体31上设置与卡扣相配合的卡接槽，通过将卡扣和卡接槽连接或拆开就可实现底板32和主体31的连接或完全拆下来。应注意地是，为了便于理解本发明，在图3中将水容纳腔30进行了倒置，并且将底板32打开了以观察水容纳腔30的内部。FIG. 3 schematically shows the internal structure of the water holding chamber 30 . The water holding chamber 30 is sealed by a main body 31 and a bottom plate 32 . The bottom plate 32 is hinged with the main body 31 so that the bottom plate 32 can be opened at any time to clean the inside of the water holding chamber 30 . It should be understood that the bottom plate 32 can also be configured to be completely detachable from the main body 31 . For example, a plurality of buckles can be provided on the edge of the bottom plate 32, and a snap-in slot matched with the snap-fits can be set on the main body 31, and the bottom plate 32 and the main body 31 can be connected or disassembled by connecting or disassembling the buckle and the snap-in slot. attached or completely detached. It should be noted that, in order to facilitate understanding of the present invention, in FIG. 3 the water containing chamber 30 is turned upside down, and the bottom plate 32 is opened to observe the inside of the water containing chamber 30 .
如图3和图4所示，其中图4是图3中的A-A剖视图，水容纳腔30通过竖直设置在其中的隔板33分隔成彼此液体连通的储液腔34和加热腔35。该隔板33是首尾相连的闭合板，从而隔板33围起来的区域形成加热腔35，而在隔板33之外的区域形成储液腔34。隔板33例如可与主体31一体成型，例如通过注塑成型。加热腔35构造为与外界连通，而储液腔34不直接与外界连通而是借助接近底板32并穿过隔板33的通道39（如图4所示）而与加热腔35液体连通，在下文中将对通道39进行详细描述。在底板32上设置有用于给加热腔35内的水加热的加热装置36，加热装置36例如可为安装在底板32上的加热板（如图4所示）或铺设在加热腔35内的电热丝，当然加热装置36还可以为其他方式，这里不再赘述。在底板32的处于储液腔34区域的部分上设置有加水孔41（如图6所示）。在加热腔35内设置有从主体31的顶壁朝向加热装置36延伸的挡板40。挡板40高于加热腔35内的液面，例如挡板40不高于加热腔35内液面以上5厘米，从而将加热腔35隔开成进气口37和出气口38。为了便于进气口37与壳体22的进风口相连通，还在水容纳腔30的侧壁上设置了进风道50。进风道50的方向与进气口37的方向大体垂直，在装配状态中，进风道50的入口与进风口相连通，出口与进气口37相连通。挡板40的横截面可为圆弧形，从而出气口38的横截面为圆弧形，其开口角度小于180度。在一个具体的实施例中，进气口37的宽度和出气口38的宽度均小于加热腔35的宽度的一半。As shown in FIGS. 3 and 4 , wherein FIG. 4 is a cross-sectional view of A-A in FIG. 3 , the water holding chamber 30 is divided into a liquid storage chamber 34 and a heating chamber 35 that are in fluid communication with each other by a partition 33 vertically disposed therein. The partition 33 is a closed plate connected end to end, so that the area surrounded by the partition 33 forms a heating chamber 35 , and the area outside the partition 33 forms a liquid storage chamber 34 . The partition 33 can be formed integrally with the main body 31, for example by injection molding. The heating chamber 35 is configured to communicate with the outside world, while the liquid storage chamber 34 is not directly communicated with the outside world but is in liquid communication with the heating chamber 35 through a channel 39 (as shown in FIG. 4 ) that is close to the bottom plate 32 and passes through the partition plate 33 . Channel 39 will be described in detail herein. A heating device 36 for heating the water in the heating chamber 35 is arranged on the base plate 32. The heating device 36 can be, for example, a heating plate (as shown in FIG. 4 ) installed on the base plate 32 or an electric heater laid in the heating chamber 35. Wire, of course, the heating device 36 can also be in other ways, which will not be repeated here. A water filling hole 41 (as shown in FIG. 6 ) is provided on the part of the bottom plate 32 in the area of the liquid storage chamber 34 . A baffle 40 extending from the top wall of the main body 31 toward the heating device 36 is disposed in the heating chamber 35 . The baffle plate 40 is higher than the liquid level in the heating chamber 35 , for example, the baffle plate 40 is not higher than 5 cm above the liquid level in the heating chamber 35 , thereby separating the heating chamber 35 into an air inlet 37 and an air outlet 38 . In order to facilitate the communication between the air inlet 37 and the air inlet of the casing 22 , an air inlet channel 50 is also provided on the side wall of the water holding chamber 30 . The direction of the air inlet channel 50 is substantially perpendicular to the direction of the air inlet 37 , and in the assembled state, the inlet of the air inlet channel 50 communicates with the air inlet, and the outlet communicates with the air inlet 37 . The cross-section of the baffle plate 40 may be arc-shaped, so the cross-section of the air outlet 38 is arc-shaped, and the opening angle thereof is less than 180 degrees. In a specific embodiment, both the width of the air inlet 37 and the width of the air outlet 38 are less than half of the width of the heating cavity 35 .
在使用时，首先将水容纳腔30倒置（如图3），并通过加水孔41向储液腔34内装入水。加水结束后，将水容纳腔30的主体31朝上放置，空气会经通道39进入到储液腔34内，从而水会自动穿过通道39流入到加热腔35内，当加热腔35内的水将通道39封住之后，水不再向加热腔35内流动。加热装置36给加热腔35内的水加热以将水蒸发出而加湿空气。当通道39再次与空气连通后，空气会经过通道39进入到储液腔34内，由此储液腔34内的水则会补充到加热腔35中。这实际上实现了加热腔35内的水量自动控制为恒定。When in use, first turn the water holding chamber 30 upside down (as shown in FIG. 3 ), and fill water into the liquid storage chamber 34 through the water filling hole 41 . After adding water, place the main body 31 of the water holding chamber 30 upwards, and the air will enter the liquid storage chamber 34 through the passage 39, so that the water will automatically flow into the heating chamber 35 through the passage 39. When the heating chamber 35 After the water seals the channel 39, the water no longer flows into the heating chamber 35. The heating device 36 heats the water in the heating chamber 35 to evaporate the water to humidify the air. When the passage 39 communicates with the air again, the air will enter the liquid storage chamber 34 through the passage 39 , and thus the water in the liquid storage chamber 34 will be replenished into the heating chamber 35 . This actually realizes that the water quantity in the heating chamber 35 is automatically controlled to be constant.
为了有效地利用热量，将储液腔34设置为包围在加热腔35的外侧周围。这样，加热腔35内的热量会向外辐射而加热储液腔34内的水，避免了热量毫无用途的向环境中散失，提高了热量的利用率。而且，由于储液腔34内的水得到预热，因此提高了加热腔35内的水的加热速度。In order to effectively utilize heat, the liquid storage chamber 34 is arranged to surround the outer periphery of the heating chamber 35 . In this way, the heat in the heating chamber 35 will radiate outwards to heat the water in the liquid storage chamber 34, which avoids the useless loss of heat to the environment and improves the utilization rate of heat. Moreover, since the water in the liquid storage chamber 34 is preheated, the heating rate of the water in the heating chamber 35 is increased.
此外，为了保证加热腔35内的水量很少，以提高加热速度，将通道39设置为其高度上限到加热装置36的距离在0.01mm-20mm之间，例如为8mm。由于加热腔35内的液面不会高于通道39，因此保证了加热腔35内的液面高度在0.01mm-20mm之间，水量非常少，因此加热速度很快。此外，加热腔35内的水量受通道39的位置控制，也就是说加热腔35内的水量是恒定的，由于加热装置36为恒定加热，因此加热腔35内的水的蒸发速率也为恒定，空气的湿度也就保持为恒定，提高了患者的体验效果。In addition, in order to ensure that the amount of water in the heating chamber 35 is small to increase the heating speed, the distance from the upper limit of the height of the channel 39 to the heating device 36 is set to be between 0.01mm-20mm, for example, 8mm. Since the liquid level in the heating chamber 35 will not be higher than the channel 39, it is ensured that the liquid level in the heating chamber 35 is between 0.01mm-20mm, and the amount of water is very small, so the heating speed is very fast. In addition, the amount of water in the heating chamber 35 is controlled by the position of the channel 39, that is to say, the amount of water in the heating chamber 35 is constant. Since the heating device 36 is constant heating, the evaporation rate of the water in the heating chamber 35 is also constant. The humidity of the air is also kept constant, which improves the experience effect of patients.
通道39构造为其过流面积与加热腔35的底面积比为0.01-0.3，例如0.15。这里，“加热腔35的底面积”是指处于加热腔35区域内的底板32的面积。在一个具体的实施例中，加热腔35的底面积为1000mm2，而通道39的过流面积为60mm2。这样，通道39的过流面积非常小，从而储液腔34内的水会缓慢进入到加热腔35内，使得加热腔内35的水温比较稳定，进一步使加热腔内35的水蒸发速度保持为恒定，空气的湿度也就保持为恒定，提高了患者的体验效果。The channel 39 is configured such that the ratio of the flow area to the bottom area of the heating chamber 35 is 0.01-0.3, for example 0.15. Here, “the bottom area of the heating chamber 35 ” refers to the area of the bottom plate 32 within the region of the heating chamber 35 . In a specific embodiment, the bottom area of the heating chamber 35 is 1000 mm2 , and the flow area of the channel 39 is 60 mm2 . In this way, the flow area of the channel 39 is very small, so that the water in the liquid storage chamber 34 will slowly enter the heating chamber 35, so that the water temperature of the heating chamber 35 is relatively stable, and further the water evaporation rate of the heating chamber 35 is maintained at Constant, the humidity of the air is also kept constant, improving the experience of patients.
为了保证加热装置36仅对加热腔35内的水加热，在一个未示出的实施例中，可将加热装置36的加热面积小于加热腔35的受热面积，这意味着隔板33与底板32密封式相连并且包围加热装置36。在另一个实施例中，如图3和4所示，还可以将加热装置36的形状构造为与加热腔35的形状相匹配，这意味着隔板33与加热装置36的边缘密封式相连。在这种情况中，通道39为在隔板33的下部区域的贯穿隔板33的过流孔，以将储液腔34和加热腔35连通。用语“隔板33的下部区域”是指隔板33接近加热装置36的区域。In order to ensure that the heating device 36 only heats the water in the heating chamber 35, in an embodiment not shown, the heating area of the heating device 36 can be smaller than the heating area of the heating chamber 35, which means that the dividing plate 33 and the bottom plate 32 It is connected in a sealed manner and surrounds the heating device 36 . In another embodiment, as shown in FIGS. 3 and 4 , it is also possible to configure the shape of the heating device 36 to match the shape of the heating chamber 35 , which means that the partition 33 is connected to the edge of the heating device 36 in a sealed manner. In this case, the channel 39 is a flow hole penetrating through the partition 33 in the lower region of the partition 33 to communicate the liquid storage chamber 34 and the heating chamber 35 . The term “the lower region of the partition 33 ” refers to the region of the partition 33 close to the heating device 36 .
图6显示了设置隔板33和加热装置36的另一种方式，在底板32上围绕加热装置36设置凸起的台阶44，隔板33与台阶44密封式相连。在这种情况中，通道39形成为贯穿台阶44而设置的凹槽43。优选地，可将台阶44设置在加热装置36的边缘处。在一个具体的实施例中，凹槽43为矩形，并且其宽度W为和长度L均小于台阶44周长的1/3。例如，台阶44周长为226.4mm，凹槽43的宽度W为1.7mm，长度L为14.6mm，高度为4.5mm。加热装置36为平面状的导热板，例如铝板或其他金属板。由于加热装置36仅对加热腔35内的水加热，因此水温能快速升高，水快速蒸发而达到快速加湿空气的目的。此外，由于凹槽43的高度为4.5mm，加热腔35内的水位必然不会高于4.5mm，加热腔35内如此少量水能够被快速加热到预定温度例如沸腾，以加湿空气。FIG. 6 shows another way of arranging the partition 33 and the heating device 36 . A raised step 44 is provided on the bottom plate 32 around the heating device 36 . The partition 33 is connected to the step 44 in a sealed manner. In this case, the channel 39 is formed as a groove 43 provided through the step 44 . Preferably, the step 44 may be provided at the edge of the heating device 36 . In a specific embodiment, the groove 43 is rectangular, and its width W and length L are both smaller than 1/3 of the circumference of the step 44 . For example, the perimeter of the step 44 is 226.4 mm, the width W of the groove 43 is 1.7 mm, the length L is 14.6 mm, and the height is 4.5 mm. The heating device 36 is a planar heat conducting plate, such as an aluminum plate or other metal plates. Because the heating device 36 only heats the water in the heating chamber 35, the water temperature can rise rapidly, and the water evaporates quickly to achieve the purpose of quickly humidifying the air. In addition, since the height of the groove 43 is 4.5 mm, the water level in the heating chamber 35 must not be higher than 4.5 mm, such a small amount of water in the heating chamber 35 can be quickly heated to a predetermined temperature such as boiling to humidify the air.
空气在进气口37内流动时，会产生噪声而影响患者的睡眠状况。为了避免噪声产生，可在进气口37中设置有消音装置。在一个实施例中，消音装置可为在进气口37内平行于气流方向而设置的多个引导板45，如图3中示意性地显示的三个引导板45。这些引导板45将进气口37分成多个彼此平行的小通道，使得空气流动更加平稳，而能避免产生噪声。需要说明的是，多个引导板45并不限于三个。When the air flows in the air inlet 37, it will generate noise and affect the sleep condition of the patient. In order to avoid noise generation, a noise reduction device may be provided in the air inlet 37 . In one embodiment, the noise reduction device can be a plurality of guide plates 45 arranged in the air inlet 37 parallel to the airflow direction, such as three guide plates 45 schematically shown in FIG. 3 . These guide plates 45 divide the air inlet 37 into a plurality of small passages parallel to each other, so that the air flow is more stable and noise can be avoided. It should be noted that the number of guide plates 45 is not limited to three.
应理解地是，虽然在实施例和附图中显示的水容纳腔30的结构为储液腔34围绕在加热腔35的外面，实际上也可以将储液腔34和加热腔35并行设置。例如在水容纳腔30内设置隔板将水容纳腔30分成左右或前后两个腔体，其中一个腔体为储液腔34，另一个为加热腔35，其余的结构与本发明的描述的结构相同，这里不再赘述。It should be understood that although the structure of the water holding chamber 30 shown in the embodiments and drawings is that the liquid storage chamber 34 surrounds the outside of the heating chamber 35 , in fact, the liquid storage chamber 34 and the heating chamber 35 can also be arranged in parallel. For example, a partition is set in the water holding chamber 30 to divide the water holding chamber 30 into two cavities, left and right or front and back, one of which is a liquid storage chamber 34, and the other is a heating chamber 35, and the rest of the structures are the same as those described in the present invention. The structure is the same and will not be repeated here.
虽然已经参考优选实施例对本发明进行了描述，但在不脱离本发明的范围的情况下，可以对其进行各种改进并且可以用等效物替换其中的部件。尤其是，只要不存在结构冲突，各个实施例中所提到的各项技术特征均可以任意方式组合起来。本发明并不局限于文中公开的特定实施例，而是包括落入权利要求的范围内的所有技术方案。While the invention has been described with reference to a preferred embodiment, various modifications may be made and equivalents may be substituted for parts thereof without departing from the scope of the invention. In particular, as long as there is no structural conflict, the technical features mentioned in the various embodiments can be combined in any manner. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
