发明内容 Summary of the invention
本发明的目的是提出一种工作噪音小、 气雾扩散面积大的加湿器。  SUMMARY OF THE INVENTION An object of the present invention is to provide a humidifier which has a small operating noise and a large aerosol diffusion area.
本发明的加湿器包括设置有储水腔、 进风口和出风口的壳体， 所述进风口和出风 口通过风道相通， 所述风道设有风机， 所述壳体内设置有超声波雾化装置、加热汽化 装置； 所述加热汽化装置由加热水槽、 加热水槽液面上方的汽化腔及电热元件构成， 所述超声波雾化装置由超声波水槽、超声波发生装置和超声波水槽液面上方的雾化腔 构成； 热水槽、 超声波水槽与储水腔通过水道相通； 关键在于所述雾化腔、汽化腔作 为风道的一部分串接于风道中。  The humidifier of the present invention comprises a housing provided with a water storage chamber, an air inlet and an air outlet, wherein the air inlet and the air outlet are communicated through a air duct, the air duct is provided with a fan, and the housing is provided with ultrasonic atomization The heating and vaporizing device comprises: a heating water tank, a vaporization chamber above the liquid level of the heating water tank, and an electric heating element, wherein the ultrasonic atomizing device is atomized by the ultrasonic water tank, the ultrasonic generating device and the ultrasonic liquid level above the liquid level The heat sink, the ultrasonic water tank and the water storage chamber communicate with each other through the water channel; the key is that the atomization chamber and the vaporization chamber are connected in series to the air passage as part of the air passage.
加湿器工作时， 超声波雾化装置和加热雾化装置同时或分别作业， 分别产生气雾 和水蒸气。 雾化腔、汽化腔串接于风道中， 这样超声波雾化装置所产生的气雾和加热 雾化装置所产生的水蒸气就会在汽化腔或雾化腔内混合，最终由出风口排出，气雾与 水蒸气相混合， 提高了气雾的温度， 有利于对气雾进行消毒及加大其扩散面积， 并且 会使气雾迅速汽化为小颗粒的蒸汽， 从而增加了汽化量。 另外， 由进风口或者雾化腔 出来的温度较低的空气或气雾会对加热水槽内的液面进行冷却，可以防止或减少液体 表面沸腾现象， 从而减小了噪声； 通过调整功率， 还可以改变出风口所散发气雾的温 度， 以适用于人体皮肤保养或卸妆。 When the humidifier is in operation, the ultrasonic atomizing device and the heating atomizing device operate simultaneously or separately to generate an aerosol and water vapor, respectively. The atomization chamber and the vaporization chamber are connected in series in the air passage, so that the aerosol generated by the ultrasonic atomization device and the water vapor generated by the heating atomization device are mixed in the vaporization chamber or the atomization chamber, and finally discharged from the air outlet. Aerosol and The mixing of water vapor increases the temperature of the aerosol, facilitates disinfection of the aerosol and enlarges its diffusion area, and rapidly vaporizes the aerosol into small particles of steam, thereby increasing the amount of vaporization. In addition, the lower temperature air or mist from the air inlet or the atomization chamber cools the liquid level in the heating water tank, which can prevent or reduce the boiling of the liquid surface, thereby reducing the noise; It can change the temperature of the aerosol emitted from the tuyere for skin care or makeup removal.
进一步地， 所述雾化腔位于进风口与汽化腔之间， 这样超声波雾化装置所产生的 气雾和加热雾化装置所产生的水蒸气就会在汽化腔内混合， 然后直接从出风口排出。 汽化腔的温度很高， 气体运动激烈， 因此提高了气雾与蒸汽的混合程度， 同时可以对 气雾进行充分杀菌； 汽化腔与出风口距离较近， 可以使出风口处的汽雾保持较高的温 度， 便于其扩散。 另外， 吹过加热水槽内的液面的进风会带走液面的热量， 同时由雾 化腔出来的温度较低的气雾会有一部分直接与加热水槽内的液面接触，迅速降低液面 温度， 可以在保持液体内部汽化速度的同时， 使液体表面不至于产生翻滚现象， 因此 可以降低因液体表面沸腾翻滚而产生的噪声。  Further, the atomization chamber is located between the air inlet and the vaporization chamber, so that the aerosol generated by the ultrasonic atomization device and the water vapor generated by the heating atomization device are mixed in the vaporization chamber, and then directly from the air outlet. discharge. The temperature of the vaporization chamber is very high, and the gas movement is fierce, so the mixing degree of the gas mist and the steam is improved, and the gas mist can be fully sterilized at the same time; the vaporization chamber is close to the air outlet, and the steam mist at the air outlet can be kept relatively High temperature for easy diffusion. In addition, the air blown through the liquid surface in the heating water tank will take away the heat of the liquid surface, and at the same time, the lower temperature mist from the atomizing chamber will directly contact the liquid surface in the heating water tank to rapidly reduce the liquid. The surface temperature can keep the liquid surface from tumbling while maintaining the internal vaporization speed of the liquid, so the noise generated by the boiling of the liquid surface can be reduced.
进一步地， 所述雾化腔位于出风口与汽化腔之间， 这样从汽化腔出来的水蒸气可 以迅速对超声波水槽内的液体进行加热， 减小超声波水槽内液体的液面张力，在不改 变超声波发生装置功率的前提下， 可以使超声波雾化装置所产生的气雾更多。  Further, the atomization chamber is located between the air outlet and the vaporization chamber, so that the water vapor from the vaporization chamber can quickly heat the liquid in the ultrasonic water tank, and reduce the liquid surface tension of the liquid in the ultrasonic water tank without changing. Under the premise of the power of the ultrasonic generating device, the ultrasonic atomizing device can generate more gas mist.
进一步地，所述加热水槽、超声波水槽通过水道或通过水道及储水腔相通，这样， 在加热水槽内的液体被加热后， 其热量会逐渐经由水道及储水腔传导到超声波水槽， 对超声波水槽内的液体进行加热，减小了超声波水槽内液体的液面张力，在不改变超 声波发生装置功率的前提下， 可以使超声波雾化装置所产生的气雾更多。  Further, the heating water tank and the ultrasonic water tank are communicated through the water channel or through the water channel and the water storage chamber, so that after the liquid in the heating water tank is heated, the heat is gradually transmitted to the ultrasonic water tank through the water channel and the water storage chamber, and the ultrasonic wave The liquid in the water tank is heated to reduce the liquid surface tension of the liquid in the ultrasonic water tank, and the ultrasonic atomizing device can generate more gas mist without changing the power of the ultrasonic generating device.
进一步地， 为加强气流对加热水槽内的液面的冷却效果， 所述风道设置有可使气 流吹向加热水槽液面的导向结构。所述导向结构可以为汽化腔的顶壁或设置于汽化腔 内的导向片，所述汽化腔的顶壁或导向片沿气流方向向下倾斜；或者所述导向结构还 可以为汽化腔气流入口处的入风道，所述入风道垂直或倾斜朝向加热水槽液面。上述 导向结构均可以使风道内的气流吹向加热水槽液面， 从而迅速降低加热水槽液面温 度， 防止或减少液体表面沸腾现象， 从而降低噪声。  Further, in order to enhance the cooling effect of the air flow on the liquid surface in the heating water tank, the air passage is provided with a guiding structure for blowing the air flow to the liquid level of the heating water tank. The guiding structure may be a top wall of the vaporization chamber or a guiding piece disposed in the vaporizing chamber, the top wall or the guiding piece of the vaporizing chamber may be inclined downward in the airflow direction; or the guiding structure may also be a vaporizing chamber air inlet At the inlet duct, the inlet duct is vertical or inclined toward the heating tank level. The above guiding structure can make the airflow in the air duct blow to the liquid surface of the heating water tank, thereby rapidly reducing the temperature of the liquid surface of the heating water tank, preventing or reducing the boiling of the liquid surface, thereby reducing noise.
进一步地， 所述汽化腔气流入口处设有扁平状的入风道， 扁平状的入风道可以扩 大进入汽化腔的气流与加热水槽液面的接触面积，因此可以迅速降低加热水槽液面温 度， 降低噪声。 进一步地， 所述出风口通过一个出风管与风道相通， 所述出风管的中部设置有直 径大于上、下两端管径的消声腔体。加热水槽内的液体沸腾时所产生的噪声声波经过 消声腔体后， 其强度会大大降低， 进一步降低了加湿器的工作噪声。 Further, a flat inlet air passage is arranged at the inlet of the vaporization chamber airflow, and the flat inlet air passage can enlarge the contact area between the airflow entering the vaporization chamber and the liquid surface of the heating water tank, thereby rapidly reducing the liquid surface temperature of the heating water tank , reduce noise. Further, the air outlet is connected to the air passage through an air outlet pipe, and the air blowing pipe is provided with a sound elimination cavity having a diameter larger than that of the upper and lower ends. When the sound waves generated by the boiling of the liquid in the heating tank pass through the muffler cavity, the intensity thereof is greatly reduced, further reducing the working noise of the humidifier.
进一步地， 所述加热水槽的底面高度高于超声波水槽的底面高度， 根据连通器的 原理，加热水槽与超声波水槽的液面高度相同，这样加热水槽内液体的深度就小于超 声波水槽的内液体的深度，在保证超声波雾化装置所必须的液体深度的前提下，加热 水槽内液体的深度较小， 有利于其内部的液体加热汽化。  Further, the height of the bottom surface of the heating water tank is higher than the height of the bottom surface of the ultrasonic water tank. According to the principle of the communicating device, the liquid level of the heating water tank and the ultrasonic water tank is the same, so that the depth of the liquid in the heating water tank is smaller than that of the ultrasonic water tank. Depth, under the premise of ensuring the liquid depth necessary for the ultrasonic atomizing device, the depth of the liquid in the heating water tank is small, which is favorable for heating and vaporizing the liquid inside.
本发明的加湿器同时设置了超声波雾化装置和加热雾化装置， 并通过独特的风道 设置， 使得加湿器的工作更加安静， 在同等能耗的状况下加大了气雾扩散面积， 提高 了实用性， 满足了客户的要求。  The humidifier of the invention is provided with an ultrasonic atomizing device and a heating atomizing device at the same time, and through the unique air channel setting, the humidifier works quieter, and the gas diffusion area is increased under the same energy consumption condition, thereby improving Practicality, to meet the requirements of customers.

加湿器工作时， 超声波雾化装置和加热雾化装置同时或分别作业， 分别产生气雾 和水蒸气。 雾化腔 6、 汽化腔 4串接于风道 13中， 这样超声波雾化装置所产生的气 雾和加热雾化装置所产生的水蒸气就会在汽化腔 4内混合， 最终由出风口 12排出， 气雾与水蒸气相混合，提高了气雾的温度，有利于对气雾进行消毒及加大其扩散面积， 并且会使大颗粒的气雾迅速汽化为小颗粒的蒸汽， 从而增加了汽化量。 另外， 由雾化 腔 6出来的温度较低的气雾会在入风道 9的导向作用下吹向加热水槽液面，对加热水 槽 3内的液面进行冷却， 可以防止或减少液体表面沸腾现象， 从而降低了噪声。更重 要的是， 在加热水槽 3内的液体被加热后， 其热量会逐渐经由水道 7、 储水腔 2、 水 道 8传导到超声波水槽 5， 对超声波水槽 5内的液体进行加热， 减小了超声波水槽 5 内液体的液面张力，在不改变超声波发生装置功率的前提下，可以使超声波雾化装置 所产生的气雾更多。通过调整风机功率， 还可以改变出风口所散发气雾的温度， 以适 用于人体皮肤保养或卸妆。 实施例 2:  When the humidifier is in operation, the ultrasonic atomizing device and the heating atomizing device operate simultaneously or separately to generate aerosol and water vapor, respectively. The atomization chamber 6 and the vaporization chamber 4 are connected in series in the air duct 13, so that the aerosol generated by the ultrasonic atomization device and the water vapor generated by the heating atomization device are mixed in the vaporization chamber 4, and finally by the air outlet 12 Exhaust, the mist and water vapor are mixed to increase the temperature of the aerosol, which is beneficial to disinfecting the aerosol and increasing its diffusion area, and rapidly vaporizing the large particles into small particles of steam, thereby increasing The amount of vaporization. In addition, the lower temperature aerosol emitted from the atomization chamber 6 is blown toward the liquid surface of the heating water tank under the guiding action of the air inlet duct 9, and the liquid surface in the heating water tank 3 is cooled to prevent or reduce the boiling of the liquid surface. Phenomenon, which reduces noise. More importantly, after the liquid in the heating water tank 3 is heated, the heat thereof is gradually transmitted to the ultrasonic water tank 5 via the water channel 7, the water storage chamber 2, and the water channel 8, and the liquid in the ultrasonic water tank 5 is heated, which is reduced. The liquid level tension of the liquid in the ultrasonic water tank 5 can make the mist generated by the ultrasonic atomizing device more without changing the power of the ultrasonic generating device. By adjusting the power of the fan, it is also possible to change the temperature of the aerosol emitted from the tuyere for skin care or makeup removal. Example 2:
