Description

鼓风通道出风口设有防水结构的超声波加湿器Ultrasonic humidifier with waterproof structure at the air outlet of the blast passage 技术领域Technical field

Blow it into the air to achieve the purpose of humidifying the air. Especially in the dry air in the north or in the dry season in winter, it is especially necessary to use an ultrasonic humidifier.

现有技术超声波加湿器有如下不足之处：超声波加湿器的鼓风通道出风口存在漏水的问题；尽管有的超声波加湿器的鼓风通道出风口结构做了一些优化，比如，有的将鼓风通道出风口加高至高出水面许多，有的将鼓风通道出风口背对着超声波雾化片或者在结构上和雾化室部分隔离(比如做"U"型筋等)，上述这些方法虽然有一定的效果，但是都不能完全解决鼓风通道出风口漏水的问题，因为鼓风通道出风口是敞开的，而雾化室内充满了细小的水珠，在加湿器停止工作的时候，悬浮的水珠或者水槽内始终会通过鼓风通道出风口进入加湿器的机体内部，造成加湿器的寿命减短或者损坏；为此，需要设计一种更加合理的结构来防止鼓风通道出风口漏水，用来解决以上的不足之处。The prior art ultrasonic humidifier has the following disadvantages: there is a problem of water leakage at the air outlet of the blast passage of the ultrasonic humidifier; although some blast air passages of the ultrasonic humidifier have been optimized, for example, some drums are used. The air passage air outlet is raised to a high level above the water surface, and some of the air outlets are opposite to the ultrasonic atomizing sheet or structurally separated from the atomizing chamber (for example, "U" type ribs, etc.). Although there is a certain effect, it can not completely solve the problem of water leakage at the air outlet of the blast passage, because the air outlet of the blast passage is open, and the atomization chamber is filled with small water droplets, and the suspension is suspended when the humidifier stops working. The water droplets or the water tank always enter the inside of the humidifier through the air outlet of the air passage, which causes the life of the humidifier to be shortened or damaged. To this end, it is necessary to design a more reasonable structure to prevent the air outlet of the air blowing passage from leaking. To solve the above deficiencies.

参见图2、图4和图9，所述出风口3111的所述鼓风通道凸柱31上设有第一小凸块 319，该第一小凸块312的作用是防止盖板321的盖板主体3211与出风口3111的周边靠得太紧后，风机组件34的风力吹不开盖板321。Referring to FIG. 2, FIG. 4 and FIG. 9, the air blowing channel protrusion 31 of the air outlet 3111 is provided with a first small bump. 319. The function of the first small bump 312 is to prevent the wind of the fan assembly 34 from blowing the cover plate 321 after the cover main body 3211 of the cover plate 321 is too tightly pressed with the periphery of the air outlet 3111.

参见图2、图5和图8，所述固定座322的顶部设有第二小凸块3229，该第二小凸块3229的作用是防止盖板321的盖板主体3211转动的角度太大而落不下来，从而导致盖不到鼓风通道311之出风口3111，也就是第二小凸块3229限制了盖板321的盖板主体3211转动的最大角度。Referring to FIG. 2, FIG. 5 and FIG. 8, the top of the fixing base 322 is provided with a second small bump 3229, and the second small bump 3229 functions to prevent the cover body 3211 of the cover plate 321 from rotating too far. However, the air outlet 3111 of the air blowing passage 311 is not covered, that is, the second small projection 3229 limits the maximum angle at which the cover main body 3211 of the cover plate 321 is rotated.

参见图6，本发明超声波加湿器工作时，超声波雾化器组件35工作将水雾化成细小的水汽颗粒，风机组件34工作将空气从鼓风通道311吹入雾化室，从而将雾化室内的水汽带到空气中进行扩散，从而达到加湿的目的；这其中，参见图5，防水结构32之盖板321在超声波加湿器的风机组件34处于工作状态时，由于气压的作用，盖板321向上旋转，鼓风通道311之出风口3111被打开，空气正常流动；参见图4，当超声波加湿器关闭不工作时，风机组件34停止工作，盖板321在自身重力的作用下，向下旋转，将鼓风通道311之出风口3111盖住封闭，从而能有效阻止雾化室内水汽从鼓风通道之出风口倒流进入加湿器的机体内部。Referring to Figure 6, when the ultrasonic humidifier of the present invention is in operation, the ultrasonic atomizer assembly 35 operates to atomize water into fine water vapor particles, and the fan assembly 34 operates to blow air from the air blowing passage 311 into the atomization chamber, thereby atomizing the chamber. The water vapor is diffused into the air for diffusion to achieve the purpose of humidification; wherein, referring to Fig. 5, the cover plate 321 of the waterproof structure 32 is in operation when the fan assembly 34 of the ultrasonic humidifier is in operation, due to the action of air pressure, the cover plate 321 Rotating upward, the air outlet 3111 of the air blowing passage 311 is opened, and the air flows normally; referring to FIG. 4, when the ultrasonic humidifier is not in operation, the fan assembly 34 stops working, and the cover plate 321 is rotated downward by its own gravity. The air outlet 3111 of the air blowing passage 311 is covered and closed, so that the water vapor in the atomizing chamber can be effectively prevented from flowing back from the air outlet of the air blowing passage into the inside of the humidifier.
