Description

Technical Field

[0001] This utility model relates to the field of humidification equipment technology, and in particular to a humidifier. Background Technology

[0002] Currently, humidifiers are commonly used to increase indoor air humidity, and are widely used in offices, bedrooms, and other places to create a comfortable working and living environment. There are two main types of existing humidifiers: heating humidifiers and ultrasonic humidifiers. The latter is more widely used due to its advantages of low energy consumption and the ability to atomize water at room temperature. Ultrasonic humidifiers utilize piezoelectric transducers to convert high-frequency electrical signals into ultrasonic vibrations of approximately 1.7 MHz, causing water droplets to break into ultrafine particles with a diameter of 1-10 μm, thus achieving the purpose of water atomization and air humidification.

[0003] The size of the water tank determines the frequency of water refills and the overall size of the product. From the user's perspective, a larger water tank means less frequent refills, reducing the burden on the user. From the factory's perspective, a smaller water tank results in a smaller product size, which is more conducive to saving materials and transportation costs. Existing humidifiers have components that are not tightly integrated, with much unnecessary space inside, which reduces the water tank capacity and results in a larger overall product size.

[0004] Therefore, how to design a humidifier that makes its components fit together more compactly, makes full use of its internal space, and reduces the overall size of the product while ensuring that the water tank capacity remains unchanged, thereby saving material and transportation costs.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0029] This utility model provides a humidifier 10, such as Figure 1 , Figure 2 and Figure 3 As shown, it includes: an upper housing 100, a lower housing 200, a water tank 300, and an electronic device 400. The water tank 300 is disposed between the upper housing 100 and the lower housing 200. The water tank 300 and the upper housing 100 form an atomizing chamber 101, and the water tank 300 and the lower housing 200 form a drying chamber 102. The electronic device 400 is housed in the drying chamber 102.

[0030] like Figure 3 and Figure 4 As shown, the top of the upper housing 100 is provided with an atomizing port 110. The water tank 300 has a water storage cavity 310, and the bottom of the water tank 300 is provided with a boss 320 and a stepped groove 330. The distance between the boss 320 and the bottom of the lower housing 200 is H1, and the distance between the stepped groove 330 and the bottom of the lower housing 200 is H2, and H1 > H2.

[0031] like Figure 2 As shown, the electronic device 400 includes: a control circuit board 410, a button 420, an ultrasonic atomizer 430, and a fan 440. The button 420 is located on the side wall of the lower housing 200. The control circuit board 410 is installed inside the drying chamber 102 and located at the boss 320. The ultrasonic atomizer 430 and the fan 440 are both electrically connected to the control circuit board 410. Furthermore, the lower housing 200 is provided with a positioning post 210, and the control circuit board 410 has a positioning hole 411 (e.g., ...). Figure 5 As shown, the control circuit board 410 is fitted onto the positioning post 210 through the positioning hole 411; a through hole 331 is provided at the stepped groove 330, and the ultrasonic atomizer 430 is installed at the through hole 331.

[0032] In use, the user adds water to the water storage chamber 310 of the water tank 300. The ultrasonic atomizer 430 is located at the bottom of the water and is in direct contact with the water. When the ultrasonic atomizer 430 is activated, it generates high-frequency vibrations, which atomize the water droplets and cause the atomized water vapor to rise. The water mist passes through the atomization chamber 101 and is finally discharged to the outside through the atomization port 110.

[0033] It should be noted that the water tank 300 of this utility model is specially designed with two parts: a boss 320 and a stepped groove 330. This design can accommodate the space requirements of both the drying chamber 102 and the water storage chamber 310. Specifically, H1 > H2, meaning that the area where the boss 320 is located in the drying chamber 102 has more space, where the control circuit board 410 and the fan 440 are installed; while in the water storage chamber 310, the area where the stepped groove 330 is located has more space, allowing the water tank 300 to make full use of the extra space in the drying chamber 102. This design makes the internal structure of the humidifier 10 more compact, making full use of its internal space, reducing the overall size of the product while ensuring the water tank capacity remains unchanged, thereby saving material and transportation costs.

[0034] Preferably, the water tank 300 is provided with a side wall 340 (e.g., Figure 4 As shown, the side wall 340 forms an obtuse angle with the bottom of the water tank 300, meaning the side wall 340 is flared outwards from bottom to top. This allows for further expansion of the water storage cavity 310 space, increasing the volume of the water tank 300.

[0035] In this embodiment, a vent 220 is provided at the bottom of the lower housing 200 (e.g., Figure 2 As shown, the vent 220 corresponds to the position of the boss 320. The fan 440 is housed within the drying chamber 102 and installed at the vent 220. The fan 440 is used to promote airflow within the drying chamber 102. Preferably, the fan 440 is an axial flow cooling fan structure, and the fan 440 is offset from the control circuit board 410. In this way, the area where the boss 320 is located within the drying chamber 102 has a relatively large height, thus not obstructing the axial flow fan 440.

[0036] In this embodiment, as Figure 5 As shown, a trigger switch 412 is provided on the control circuit board 410, and the trigger switch 412 is soldered onto the control circuit board 410 in a surface mount manner. A button 420 abuts against the trigger switch 412. In the prior art, the trigger switch 412 and the control circuit board 410 are usually manually soldered. The trigger switch 412 needs to be fixed to the control circuit board 410 by a bracket. The bracket's function is to fix the trigger switch 412 while providing sufficient space for the worker's soldering operation, thus facilitating the soldering process. However, this embodiment uses a surface mount soldering method, which reduces the need for a bracket and manual operation, thereby reducing costs and increasing standardization.

[0037] In this embodiment, as Figure 3 As shown, a guide sleeve 120 is provided at the atomizing port 110 of the upper housing 100. The guide sleeve 120 extends towards the atomizing chamber 101, and the inner wall of the guide sleeve 120 forms a funnel-shaped structure. During operation, at the atomizing port 110, some water mist is intercepted and condenses into water droplets on the inner wall. The funnel-shaped guide sleeve 120 has the function of guiding the water droplets back into the water tank 300.

[0038] Preferably, the inner wall of the upper housing 100 is further provided with a drainage plate 130 (e.g., Figure 3 As shown, the guide plate 130 has an annular structure and extends into the interior of the water storage chamber 310. During operation, water droplets flowing back along the inner wall of the upper housing 100 are guided into the water storage chamber 310 by the guide plate 130, so that the flowing water droplets will not enter the drying chamber 102.

[0039] Preferred, such as Figure 6As shown, the lower housing 200 has a clearance groove 230, and the control circuit board 410 has a charging port 413, which communicates with the clearance groove 230. Furthermore, the bottom of the lower housing 200 has a raising foot 240. During charging, the user plugs the charging cable into the charging port 413. The raising foot 240 provides necessary space for the charging cable to pass through, and the clearance groove 230 provides ample space for the charging cable's connector. This bottom-charging design makes the humidifier 10 more aesthetically pleasing. In addition, the clearance groove 230 conceals the connector and the charging port 413, preventing external water mist from falling into the charging port 413 and causing circuit malfunctions.

[0040] In summary, the humidifier 10 of this utility model enables the components to fit together more compactly, making full use of its internal space and reducing the overall size of the product while ensuring that the water tank capacity remains unchanged, thereby saving material and transportation costs.

[0041] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
