[0044] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining this utility model and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to this utility model are shown in the drawings, not all of them.

[0045] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0046] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0047] In the description of this embodiment, the terms "upper," "lower," "left," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0048] like Figure 1 As shown in the figure, this disclosure provides an air humidification device 100, which can be a humidifier, an integrated air purifier and humidifier, a sprayer, etc. All devices capable of humidifying the air are within the protection scope of this application.

[0049] like Figure 1 As shown, the air humidification device 100 includes a water tank 10, a wet curtain support assembly 20, a water pump assembly 30, and a wet curtain 40. The water tank 10 has a water storage chamber 11 and is used to store liquid for humidification. The liquid can be water, a fragranced liquid, etc. All liquids that can be used to humidify the environment are within the protection scope of this application. For other materials of the humidification liquid, refer to mature products in the prior art. This application will not elaborate on them further.

[0050] like Figure 1 As shown, at least part of the evaporative cooling pad support assembly 20 is located within the water storage chamber 11 and connected to the water tank 10. The evaporative cooling pad 40 is positioned at the upper end of the evaporative cooling pad support assembly 20, which supports the evaporative cooling pad 40 and provides stable support. Figure 1As shown, the water pump assembly 30 includes a water pump body 32 and a connecting pipe 34. One end of the connecting pipe 34 is connected to the water pump body 32, and the other end of the connecting pipe 34 is connected to the wet curtain 40. At least part of the water pump body 32 is located in the liquid in the water tank 10. The water pump body 32 pumps the liquid in the water tank 10 to the top of the wet curtain 40 for watering. When the wet curtain 40 is saturated with water, the excess water will flow back to the bottom of the water tank 10 and the wet curtain 40 will be circulated and watered through the water pump body 32.

[0051] In addition, the air humidification device 100 also includes a blower mechanism (not shown in the figure), which blows air onto the wet curtain 40. The airflow blown out by the blower mechanism carries the moisture on the wet curtain 40 into the environment to achieve humidification of the environment.

[0052] The existing water pump body 32 is only connected to the wet curtain 40 through the connecting pipe 34. The water pump body 32 is suspended in the water tank 10 and there is no contact between the water pump body 32 and the water tank 10. When the water pump body 32 is pumping water, it generates a lot of vibration and shaking. The air humidifier 100 also generates a lot of vibration and shaking. Moreover, the air humidifier 100 has a lot of noise, which affects the user's experience.

[0053] To solve the above problems, such as Figure 1 As shown, the air humidifier 100 includes a water tank 10, a wet curtain support assembly 20, and a water pump assembly 30. The water tank 10 has a water storage chamber 11. At least a portion of the wet curtain support assembly 20 is located within the water storage chamber 11 and connected to the water tank 10. The water pump assembly 30 is disposed within the water storage chamber 11 and fixedly connected to the wet curtain support assembly 20. The water tank 10 and the wet curtain support assembly 20 form a stable integrated structure. Small-amplitude vibrations generated by the water pump assembly 30 during operation are first transmitted to the wet curtain support assembly 20, and then from the wet curtain support assembly 20 to the water tank 10. The vibrations generated by the water pump assembly 30 are transmitted to the overall structure and absorbed by the overall structure. Kinetic energy is dissipated during the transmission of the vibrations generated by the water pump assembly 30. The overall structure can effectively absorb the kinetic energy generated by the water pump assembly 30, thereby eliminating the vibrations generated by the water pump assembly 30. This effectively reduces vibration, shaking, and noise during the use of the air humidifier 100, ensuring a better user experience.

[0054] In an alternative embodiment, such as Figures 1-3As shown, the water pump assembly 30 includes a mounting frame 31 and a water pump body 32. The mounting frame 31 is fixedly connected to the evaporative cooling pad support assembly 20, and the water pump body 32 is mounted on the mounting frame 31. The water pump body 32 is the main structure that generates vibration. The mounting frame 31, the water tank 10, and the evaporative cooling pad support assembly 20 form a stable integrated structure. The vibration generated by the water pump body 32 is transmitted to and absorbed by the integrated structure, which effectively absorbs the vibration generated by the water pump body 32. Furthermore, the vibration generated by the water pump body 32 is first transmitted to the mounting frame 31, then to the evaporative cooling pad support assembly 20, and finally to the water tank 10. This longer vibration transmission path improves the overall structure's absorption of the kinetic energy generated by the water pump body 32, thus achieving better absorption of the vibration generated by the water pump body 32.

[0055] In an alternative embodiment, such as Figures 1-3 As shown, the water pump assembly 30 also includes a liquid level detection mechanism 33, which is used to detect the liquid level in the water storage chamber 11, and can solve problems such as a large amount of residual water in the water storage chamber 11, the water pump body 32 not working, and the water pump body 32 running dry.

[0056] In an alternative embodiment, such as Figures 1-3 As shown, the liquid level detection mechanism 33 is mounted on the mounting frame 31. The mounting frame 31 provides stable support for the liquid level detection mechanism 33, thereby enabling the liquid level detection mechanism 33 to accurately detect the liquid level in the water tank 10. Furthermore, since the water pump body 32 and the liquid level detection mechanism 33 are mounted on the mounting frame 31, the mounting frame 31, the water pump body 32, and the liquid level detection mechanism 33 form an integrated module. This integrated module facilitates the quick and accurate assembly of the water pump assembly 30 and the wet curtain support assembly 20.

[0057] In an alternative embodiment, such as Figure 2 and Figure 3 As shown, the liquid level detection mechanism 33 is an ultrasonic liquid level detection mechanism. Compared with an external float sensor, the ultrasonic liquid level detection mechanism does not rely on the buoyancy of the liquid. As long as there is liquid above the ultrasonic liquid level detection mechanism, it can be detected. After the controller of the air humidification device 100 determines that the conditions are met, it can control the water pump assembly 30 to work normally or shut down. The ultrasonic liquid level detection mechanism can detect the liquid level in the water tank 10 more accurately, solving problems such as a large amount of residual water in the water tank 10 and the water pump not working and dry pumping.

[0058] In an alternative embodiment, such as Figures 1-3As shown, the mounting bracket 31 has a first receiving cavity 3111. At least part of the water pump body 32 is inserted into the first receiving cavity 3111 and is interference-fitted with the inner wall of the first receiving cavity 3111. The rigid fitting of the water pump body 32 and the mounting bracket 31 significantly improves the assembly stability of the water pump body 32, and can achieve a stable connection between the water pump body 32 and the mounting bracket 31, preventing the water pump body 32 from loosening and falling off the mounting bracket 31 during vibration.

[0059] In an alternative embodiment, such as Figures 1-3 As shown, the mounting bracket 31 has a second receiving cavity 3112. At least part of the liquid level detection mechanism 33 is inserted into the second receiving cavity 3112 and is interference-fitted with the inner wall surface of the second receiving cavity 3112. The rigid fitting of the liquid level detection mechanism 33 and the mounting bracket 31 significantly improves the assembly stability of the liquid level detection mechanism 33, and can achieve a stable connection between the liquid level detection mechanism 33 and the mounting bracket 31, preventing the liquid level detection mechanism 33 from loosening and falling off the mounting bracket 31 during vibration.

[0060] In an alternative embodiment, such as Figures 1-3 As shown, the mounting bracket 31 includes a housing 311 and an abutment member 312. The abutment member 312 is formed by extending from the inner surface of the housing 311 toward the interior of the housing 311. The free end of the abutment member 312 abuts against the outer surface of the water pump body 32. The abutment between the abutment member 312 and the water pump body 32 can further improve the stable connection between the mounting bracket 31 and the water pump body 32.

[0061] In an alternative embodiment, such as Figure 3 As shown, the abutment 312 includes a first abutment 3121 and a second abutment 3122. The extension direction of the first abutment 3121 is different from that of the second abutment 3122. By setting the first abutment 3121 and the second abutment 3122, the mounting bracket 31 can achieve a circumferential all-round limiting effect on the water pump body 32, and can prevent the water pump body 32 from being displaced relative to the mounting bracket 31.

[0062] In an alternative embodiment, such as Figure 3 As shown, the first abutment member 3121 includes a first guide surface 31211. Along the insertion direction M of the water pump body 32, the first guide surface 31211 is inclined from the inner surface of the housing 311 toward the inside of the housing 311. Through the sliding cooperation between the water pump body 32 and the first guide surface 31211, the first guide surface 31211 can achieve a better guiding and centering effect for the water pump body 32, and achieve a precise and fast installation effect of the water pump body 32 onto the mounting bracket 31.

[0063] In an alternative embodiment, such as Figure 3As shown, the second abutment member 3122 includes a second guide surface 31221. Along the insertion direction M of the water pump body 32, the second guide surface 31221 is inclined from the inner surface of the housing 311 toward the inside of the housing 311. Through the sliding cooperation between the water pump body 32 and the second guide surface 31221, the second guide surface 31221 can achieve a better guiding and centering effect for the water pump body 32, and achieve a precise and fast installation effect of the water pump body 32 onto the mounting bracket 31.

[0064] In an optional embodiment, the water tank 10 includes a first base plate 12 with a downwardly protruding groove 121. At least a portion of the water pump assembly 30 is housed in the groove 121, and the water pump assembly 30 is arranged close to the bottom surface of the groove 121. The shape of the groove 121 allows the water tank 10 to concentrate residual liquid into the groove 121 when the liquid level is low, ensuring that the suction port of the water pump assembly 30 is always submerged in the residual liquid in the groove 121. Even if the total liquid level in the water tank 10 drops below the safety threshold, the water pump assembly 30 can still perform pumping operations, reducing the residual liquid in the water tank 10 and preventing the water pump assembly 30 from running dry. This ensures that the water pump assembly 30 can still meet the pumping conditions when the air humidification device 100 detects a lack of liquid.

[0065] In an alternative embodiment, such as Figures 1-3 As shown, the wet curtain support assembly 20 includes a wet curtain support 21 and a wet curtain support 22. The bottom of the wet curtain support 21 abuts against the bottom of the water tank 10. The wet curtain support 22 is disposed at the upper end of the wet curtain support 21. The outer edge 221 of the wet curtain support 22 overlaps the top 13 of the water tank 10. The wet curtain support 22 is used to support the wet curtain 40. The wet curtain support 21 and the wet curtain support 22 cooperate with the water tank 10 to achieve stable support of the wet curtain support assembly 20 by the water tank 10.

[0066] Specifically, such as Figures 1-3 As shown, the wet curtain support 22 includes an outer edge 221, a support body 222, and a plug-in end 223 connected sequentially from top to bottom. The wet curtain support 22 is located above the wet curtain bracket 21, which has an upper opening 2112. The outer edge 221 overlaps the top 13 of the water tank 10, and the plug-in end 223 is at the upper opening 2112. This enables a stable connection between the wet curtain support 22, the wet curtain bracket 21, and the water tank 10, thereby achieving a stable connection between the wet curtain bracket assembly 20 and the water tank 10.

[0067] In an alternative embodiment, such as Figure 2 and Figure 3As shown, the evaporative cooling pad bracket 21 includes a main body 211 and a shield 212. The shield 212 is detachably connected to the main body 211 and together with the main body 211 forms a cavity 213. The water pump assembly 30 is housed in the cavity 213 and is detachably connected to the main body 211 via the shield 212. On the one hand, this prevents foreign objects from entering the cavity 213 and interfering with the operation of the water pump assembly 30. On the other hand, when maintaining the water pump assembly 30, it is not necessary to disassemble the evaporative cooling pad bracket 21 or the water tank 10; the water pump assembly 30 can be directly accessed for maintenance simply by opening the shield 212.

[0068] Specifically, such as Figure 2 and Figure 3 As shown, the cavity 213 includes a first sub-cavity 2131 and a second sub-cavity 2132. The first sub-cavity 2131 has an opening 21311 and is disposed on the wet curtain support 21. The second sub-cavity 2132 is disposed on the shielding member 212. The shielding member 212 is disposed on the opening 21311 and is detachably connected to the wet curtain support 21.

[0069] In an alternative embodiment, such as Figure 2 As shown, the main body 211 of the wet curtain support includes a second base plate 2113, and a first drain hole 21131 is provided on the second base plate 2113, through which the liquid in the water tank 10 can enter the cavity 213.

[0070] In an alternative embodiment, such as Figure 2 As shown, the main body 211 of the wet curtain support includes a third base plate 2122, and a second drain hole 21221 is provided on the third base plate 2122. The liquid in the water tank 10 can enter the cavity 213 through the second drain hole 21221.

[0071] In an alternative embodiment, such as Figure 2 As shown, the evaporative cooling pad bracket 21 includes a fixing member 214, which can pass through the evaporative cooling pad bracket body 211 and the shielding member 212, thereby enabling a detachable connection between the evaporative cooling pad bracket body 211 and the shielding member 212. For example, the fixing member 214 can be a screw, pin, nut, snap-fit ​​assembly, magnetic assembly, etc. All structures capable of enabling a detachable connection between the evaporative cooling pad bracket body 211 and the shielding member 212 are within the scope of protection of this application. For other structures of the fixing member 214, refer to mature products in the prior art; this application will not elaborate further.

[0072] In an alternative embodiment, such as Figure 2 and Figure 3As shown, the wet curtain bracket 21 includes a fixing member 214, the water pump assembly 30 includes a lug 313, the shielding member 212 includes a first connecting post 2121, and the wet curtain bracket body 211 includes a second connecting post 2111. The first connecting post 2121 and the second connecting post 2111 are located on both sides of the lug 313. The fixing member 214 is sequentially inserted through the first connecting post 2121, the lug 313, and the second connecting post 2111, which can realize a stable connection between the wet curtain bracket 21 and the water pump assembly 30 in the radial and axial directions.

[0073] In an alternative embodiment, such as Figure 2 and Figure 3 As shown, a first limiting groove 3131 is provided on the lug 313, wherein the first connecting post 2121 is inserted into the first limiting groove 3131. The first connecting post 2121 and the first limiting groove 3131 cooperate to achieve radial limiting of the first connecting post 2121, ensuring a stable connection between the mounting bracket 31 and the wet curtain bracket 21.

[0074] In an alternative embodiment, such as Figure 2 and Figure 3 As shown, a second limiting groove 3132 is provided on the lug 313, wherein the second connecting post 2111 is inserted into the second limiting groove 3132. The second connecting post 2111 and the second limiting groove 3132 cooperate to achieve radial limiting of the second connecting post 2111, ensuring a stable connection between the mounting bracket 31 and the wet curtain bracket 21.

[0075] In an alternative embodiment, such as Figure 2 and Figure 3 As shown, at least two lugs 313 are provided, each lug 313 is provided with a first connecting post 2121 corresponding to it, and each lug 313 is provided with a second connecting post 2111 corresponding to it.
