[0036] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the following will be combined with the accompanying drawings to make a clear and complete description of the technical solutions in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. The components of the embodiments of the present application described and shown in the accompanying drawings can be arranged and designed in various different configurations.

[0037] In the description of the present application, it should be noted that the positions or location relationships indicated by the terms "inner", "outer" and the like are based on the positions or location relationships shown in the drawings, or the positions or location relationships in which the products of the present application are usually placed, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first", "second" and the like are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0038] In the description of the present application, it should be noted that, unless otherwise explicitly specified and limited, the terms "set", "connected" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be directly connected, or indirectly connected through an intermediate medium, or it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0039] The embodiments of the present application provide a waterproof mounting shell 300, a waterproof top shell 400 and a humidifier 1000, the waterproof mounting shell 300 and the waterproof top shell 400 can be mounted on the humidifier 1000, and are used for preventing the circuit board in the humidifier 1000 from being short-circuited due to accidental water ingress.

[0040] In a first aspect, the embodiments of the present application provide a waterproof mounting shell 300, which comprises a mounting piece 310 and a partition piece 320.

[0041] The mounting piece 310 is provided with a first electronic board mounting position. Exemplarily, the mounting piece 310 is a planar plate structure, and the first electronic board mounting position is used for mounting a circuit board, such as Figure 8 As shown, the circuit board is, for example, a PCBA (Printed Circuit Board Assembly). Exemplarily, the electronic board mounting position is provided with an electronic board mounting column, the first electronic board mounting position is arranged on the mounting column, and the PCBA is connected with the mounting piece 310 through the electronic board mounting column; a plurality of electronic board mounting columns are arranged.

[0042] As shown in Figure 8 to Figure 10As shown, the partitioning member 320 is fixedly arranged on the mounting member 310 around the first electronic board mounting position, that is, the partitioning member 320 is arranged on the mounting member 310 around the four sides of the first electronic board mounting position, Figure 8 and Figure 9 The arrow in the figure represents the direction of liquid flow. The partitioning member 320 is located in the initial flow path of the liquid. After the liquid contacts the partitioning member 320, the partitioning member 320 guides the flow of the liquid, causing the liquid to flow over the partitioning member 320 and bypass the first electronic board mounting position. The partitioning member 320 blocks the liquid from entering the PCBA at the first electronic board mounting position.

[0043] As shown in Figure 9 , a surrounding plate 330 is arranged protruding along the extension direction of the partitioning member 320. The surrounding plate 330 is used to limit the flow path of the liquid on the partitioning member 320.

[0044] The waterproof mounting shell 300 provided by the embodiments of the present application provides a mounting position for the electronic board through the mounting member 310. The partitioning member 320 is arranged on the mounting member 310 around the first electronic board mounting position, effectively blocking the liquid (such as water) from directly entering the area of the circuit board (such as the first PCBA 100). This design can significantly reduce the risk of short circuit of the circuit board caused by accidental water ingress, thereby improving the safety and reliability of the humidifier 1000.

[0045] The partitioning member 320 not only blocks the liquid from entering the first electronic board mounting position, but also guides the flow of the liquid. When the liquid contacts the partitioning member 320, it will be guided to flow along the surface of the partitioning member 320, thereby bypassing the critical circuit board area. This design helps to ensure that the liquid does not accumulate near the circuit board, further reducing the risk of short circuit.

[0046] The protruding design of the surrounding plate 330 limits the flow path of the liquid, ensuring that the liquid is limited on the partitioning member 320, and even if the volume of liquid on the partitioning member 320 is relatively large, it cannot easily penetrate into the first circuit board mounting position. This additional sealing measure provides more comprehensive protection for the circuit board.

[0047] Through effective waterproof design, the durability of the PCBA is significantly improved. The circuit board is one of the core components of the humidifier 1000, and the enhancement of its safety directly prolongs the service life of the product and reduces the maintenance or replacement cost caused by water damage.

[0048] As shown in Figure 8 and Figure 9 , in one embodiment, the mounting member 310 is vertically arranged, and the mounting member 310 includes a first mounting end portion 311, a second mounting end portion 312, a third mounting end portion 313, and a fourth mounting end portion 314.

[0049] AsFigure 8 and Figure 9 As shown in

[0050] As shown in Figure 8 and Figure 9 The installation member 310 is vertically arranged, the first installation end 311 is a horizontal end of the installation member 310, and the first baffle plate 321 is horizontally arranged and perpendicular to the first installation end 311.

[0051] As shown in Figure 9 The installation member 310 is vertically arranged, the first installation end 311 is a horizontal end of the installation member 310, and the first baffle plate 321 is horizontally arranged and perpendicular to the first installation end 311.

[0052] Exemplarily, the first baffle plate 321 is fixedly arranged on the first installation end 311 by welding, clamping, gluing, or one-piece forming, etc.

[0053] The first baffle plate 321 is vertically arranged on the first installation end 311, effectively blocking the liquid from flowing directly to the first electronic board mounting position. This directional blocking design ensures that the circuit board area is not affected by the liquid, thereby improving the waterproof performance of the device.

[0054] The vertical arrangement of the installation member 310 and the design of the first installation end 311 as a horizontal end provide a stable mounting basis for the first baffle plate 321. This structural layout enhances the stability of the entire mechanical structure, making the device less prone to deformation or damage during long-term use.

[0055] The first baffle plate 321 is provided with a surrounding plate 330, which guides the liquid on the first baffle plate 321 to flow in the direction of the two sides of the first baffle plate 321.

[0056] The arrangement of the surrounding plate 330 further guides the liquid to flow in the direction of the two sides of the first baffle plate 321, preventing the liquid from accumulating on the baffle plate and possibly penetrating into the circuit board area, thereby enhancing the waterproof effect.

[0057] The vertical arrangement of the installation member 310 and the layout design of the first baffle plate 321 and the surrounding plate 330 fully consider the space utilization inside the device. This design enables effective arrangement of the waterproof structure in a limited space without interfering with the installation of other components.

[0058] Of course, in other embodiments, the first mounting end portion 311 is a roof-like inverted V-shaped protruding end portion, and the first baffle plate 321 is configured as an inverted V-shaped plate body structure that matches the first mounting end portion 311. The first baffle plate 321 of the inverted V-shaped plate body structure can accelerate the flow of liquid.

[0059] As shown in FIG. 3, in one embodiment, the baffle member 320 further includes a second baffle plate 322 and a third baffle plate 323. Figure 8 to Figure 10

[0060] As shown in FIG. 3, in one embodiment, the baffle member 320 further includes a second baffle plate 322 and a third baffle plate 323. Figure 8

[0061] As shown in FIG. 3, in one embodiment, the baffle member 320 further includes a second baffle plate 322 and a third baffle plate 323. Figure 10

[0062] As shown in FIG. 3, in one embodiment, the baffle member 320 further includes a second baffle plate 322 and a third baffle plate 323.

[0063] The first baffle plate 321 is connected to the second baffle plate 322 at one end and to the third baffle plate 323 at the other end, so that the baffle member 320 forms a H-shaped plate body structure. Liquid flowing from both sides of the first baffle plate 321 flows onto the second baffle plate 322 and the third baffle plate 323, respectively, and the second baffle plate 322 and the third baffle plate 323 block the flow of liquid into the first electronic board mounting position.

[0064] The baffle member 320 is composed of the first baffle plate 321, the second baffle plate 322, and the third baffle plate 323, forming a H-shaped plate body structure that effectively blocks the flow of liquid from multiple directions into the first electronic board mounting position. The design of the H-shaped plate body structure allows liquid flowing from both sides of the first baffle plate 321 to flow onto the second baffle plate 322 and the third baffle plate 323, respectively, further blocking and guiding the flow of liquid, ensuring the dryness and safety of the electronic board mounting position.

[0065] ​​​The H-shaped plate structure of the partition member 320 and the setting of the surrounding edge plate 330 enhance the stability and rigidity of the entire mechanical structure. This structural layout makes the device not easy to deform or damage when subjected to external force, thereby improving the durability of the device.

[0066] As shown in FIG. 1, in one embodiment, the partition member 320 further comprises a first flow guide plate 324, which is an H-shaped plate structure, and the first flow guide plate 324 is arranged on the second mounting end portion 312 and is connected with the second partition plate 322. The plate structure of the first flow guide plate 324 connected with the second partition plate 322 has an included angle with the second partition plate 322. The liquid flowing out of the second partition plate 322 flows onto the first flow guide plate 324, and the first flow guide plate 324 changes the flow direction of the liquid, thereby reducing the flow rate of the liquid. Figure 8 Figure 9 As shown in FIG. 1, in one embodiment, the partition member 320 further comprises a first flow guide plate 324, which is an H-shaped plate structure, and the first flow guide plate 324 is arranged on the second mounting end portion 312 and is connected with the second partition plate 322. The plate structure of the first flow guide plate 324 connected with the second partition plate 322 has an included angle with the second partition plate 322. The liquid flowing out of the second partition plate 322 flows onto the first flow guide plate 324, and the first flow guide plate 324 changes the flow direction of the liquid, thereby reducing the flow rate of the liquid.

[0067] Exemplarily, the first flow guide plate 324 comprises a first end portion 324a, a second end portion 324b and a third end portion 324c. One end of the second end portion 324b is connected with the first end portion 324a, and the other end of the third end portion 324c is connected with the second end portion 324b. The second end portion 324b is vertically arranged, and the first end portion 324a and the third end portion 324c are horizontally arranged. The first flow guide plate 324 is connected with the second partition plate 322 through the first end portion 324a, and the second partition plate 322 is vertically connected with the first end portion 324a. Therefore, the included angle between the first flow guide plate 324 and the second partition plate 322 is 90°. The second end portion 324b is vertically arranged on the second mounting end portion 312, and the third end portion 324c is vertically arranged on the second mounting end portion 312.

[0068] The liquid flows from the second mounting end portion 312 onto the first end portion 324a, and then flows from the first end portion 324a onto the second end portion 324b. When the liquid flows onto the first end portion 324a, the flow direction changes, thereby reducing the flow rate of the liquid on the second end portion 324b, and preventing the liquid from splashing onto other components when dripping from the second end portion 324b at too high a speed.

[0069] The H-shaped plate structure of the first flow guide plate 324 is connected with the second partition plate 322, and the included angle between them is 90°. This design makes the liquid flowing out of the second partition plate 322 change the flow direction when flowing onto the first end portion 324a of the first flow guide plate 324, and then flows onto the second end portion 324b. In this process, the flow rate of the liquid is effectively reduced, preventing the liquid from dripping from the second end portion 324b at too high a speed.

[0070] As shown in FIG. 1, in one embodiment, the partition member 320 further comprises a first flow guide plate 324, which is an H-shaped plate structure, and the first flow guide plate 324 is arranged on the second mounting end portion 312 and is connected with the second partition plate 322. The plate structure of the first flow guide plate 324 connected with the second partition plate 322 has an included angle with the second partition plate 322. The liquid flowing out of the second partition plate 322 flows onto the first flow guide plate 324, and the first flow guide plate 324 changes the flow direction of the liquid, thereby reducing the flow rate of the liquid. Figure 9 ​As shown in the drawings, in one embodiment, the first guide plate 324 is provided with a surrounding plate 330. The first end 324a, the second end 324b and the third end 324c are all provided with the surrounding plate 330. The surrounding plate 330 limits the liquid on the first guide plate 324.

[0071] As shown in the drawings, Figure 10 As shown in the drawings, in one embodiment, the third mounting end 313 is only provided with the third baffle plate 323. But in another embodiment, the third mounting end 313 is provided with the third baffle plate 323 and a second guide plate. Exemplarily, the baffle piece 320 further comprises a second guide plate, which is a similar H-shaped plate structure to the first guide plate 324, and is arranged on the fourth mounting end 314. The second guide plate is connected with the third baffle plate 323, and the plate structure of the second guide plate connected with the third baffle plate 323 has an included angle with the third baffle plate 323. The liquid flowing out of the third baffle plate 323 flows onto the second guide plate, and the second guide plate reduces the flow rate of the liquid. In one embodiment, the second guide plate is provided with a surrounding plate 330.

[0072] As shown in the drawings, Figure 10 As shown in the drawings, in one embodiment, the baffle piece 320 further comprises a water guide plate 326, which is arranged on the third mounting end 313 and is an H-shaped plate structure.

[0073] Exemplarily, the water guide plate 326 comprises a first stop end, a second stop end and a third stop end. One end of the second stop end is fixedly connected with the first stop end, and the other end of the second stop end is fixedly connected with the third stop end, so as to form the H-shaped water guide plate 326. The fixedly connected manner includes but is not limited to welding, clamping, gluing or one-piece forming, etc.

[0074] The second stop end is fixedly connected with the third end 324c, the first stop end is fixedly connected with the third end 324c, and the third stop end is fixedly connected with the third baffle plate 323.

[0075] In a second aspect, the embodiments of the present application also provide a waterproof top cover 400, as shown in the drawings, Figure 4 to Figure 6 The waterproof top cover 400 comprises a top cover body 410 and a surrounding plate 420.

[0076] The top cover body 410 is provided with a second electronic board mounting position for mounting an electronic board, such as the second PCBA 200. Exemplarily, the top cover body 410 is provided with a mounting column, which provides a basis for the mounting of the second PCBA 200.

[0077] The top cover body 410 has a top end face and a bottom end face.

[0078] AsFigure 6 and Figure 7 As shown, a retaining plate 420 is disposed at the bottom end face and surrounds the second electronic board mounting position. Exemplarily, the retaining plate 420 is used to prevent liquid from flowing to the second electronic board mounting position.

[0079] For example, the enclosure 420 is vertically arranged, and the liquid on the enclosure 420 flows vertically.

[0080] The enclosure 420 effectively prevents liquid from flowing into the second electronic board mounting location, thus providing waterproof protection. This is crucial for electronic equipment that needs to be protected from moisture, extending its lifespan and improving its reliability.

[0081] Thirdly, such as Figure 1 As shown, embodiments of this application also provide a humidifier 1000, such as... Figure 2 and Figure 3 As shown, the humidifier 1000 includes a first PCBA 100 and a waterproof mounting housing 300 as described in any of the above embodiments.

[0082] like Figure 4 and Figure 8 As shown, the first PCBA100 is disposed on the first electronic board mounting position, and the first PCBA100 is disposed parallel to the mounting component 310.

[0083] For example, a display is provided on the humidifier 1000, a first PCBA 100 is electrically connected to the display, the display is vertically mounted on the housing of the humidifier 1000, the first PCBA 100 is vertically mounted on the mounting part 310 of the waterproof mounting housing 300, and the mounting part 310 is vertically mounted on the frame of the humidifier 1000.

[0084] like Figure 1 As shown, in one embodiment, the humidifier 1000 includes a second PCBA 200 and a waterproof top shell 400 as in any embodiment, the second PCBA 200 being disposed on a second electronic board mounting position.

[0085] Figure 7 In the diagram, the arrow on the enclosure 420 indicates the direction of liquid flow. During the process of adding water or other liquids to the humidifier 1000 from the top housing, some liquid may enter the humidifier 1000 from the gap between the waterproof top housing 400 and the outer casing of the humidifier 1000, affecting the safe use of the second PCBA 200. The enclosure 420 prevents liquid from entering the second electronic board mounting position and guides the liquid flow to prevent liquid accumulation.

[0086] like Figure 6As shown, in the direction of gravity, the height of the lowest part on the surrounding plate 420 is less than the height of the lowest part on the second PCBA 200, so that the liquid on the surrounding plate 420 will not flow back to the second PCBA 200 at the second electronic board mounting position due to oscillation or the like.

[0087] The humidifier 1000 provided by the embodiments of the present application has a significantly improved durability through an effective waterproof design. The enhancement of the safety of the circuit board, which is one of the core components of the humidifier 1000, directly prolongs the service life of the product and reduces the maintenance or replacement cost caused by water damage.

[0088] It should be noted that the features in the embodiments of the present application can be combined with each other without conflict.

[0089] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Various modifications and changes can be made by those skilled in the art based on the spirit and principles of the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
