[0008] A first sealing ring sleeved on the upper end of the connecting shaft;

[0009] A second sealing ring sleeved on the lower end of the connecting shaft.

[0010] Further, the supplementary water tank body has an internal thread section that is in threaded cooperation with the external thread section.

[0011] Further, the first sealing ring abuts against the upper end surface of the supplementary water tank body, and the second sealing ring abuts against the upper water inlet of the supplementary water tank body.

[0012] Further, the screw cap has a convex ring portion located outside the connecting shaft, the top of the first sealing ring abuts against the convex ring portion, and the inner side of the convex ring portion has a first annular groove, and the upper end of the first sealing ring has a protruding portion adapted to the first annular groove.

[0013] Still further, the lower end of the first sealing ring has an annular convex lip that abuts against the upper end surface of the supplementary water tank body.

[0014] Further, a second annular groove for installing the second sealing ring is formed on the connecting shaft, and the second sealing ring has a main sealing lip and a secondary sealing lip that extend outward and abut against the upper water inlet.

[0015] A humidifier includes a water tank sealing structure, and further includes:

[0016] A housing, a water tank connected to the water replenishing tank body is arranged at the lower end of the housing;

Detailed implementation manners

[0034] To make the purpose, technical solutions and advantages of the present application clearer and more understandable, the present application will be further described in detail below in combination with the implementation manners and the drawings. Herein, the illustrative implementation manners of the present application and their descriptions are used to explain the present application, but do not limit the present application.

[0035] Refer to Figures 1 to 6 As Figure 1 and Figure 4 shown, the present embodiment provides a water tank sealing structure for sealing the water inlet provided at the upper end of the water replenishing tank body 31. The water tank sealing structure 5 includes: a screw cap 51, a first sealing ring 52 and a second sealing ring 53. The lower end of the screw cap 51 has a connecting shaft 511 and an external thread section 512 integrally connected from top to bottom. The water inlet includes a communicated upper water inlet 311 and a lower water inlet 313. The external thread section 512 is in threaded cooperation with the lower water inlet 313. The first sealing ring 52 is sleeved on the upper end of the connecting shaft 511. The second sealing ring 53 is sleeved on the lower end of the connecting shaft 511, and the second sealing ring 53 abuts against the upper water inlet 311.

[0036] As Figure 5As shown, the water replenishing tank body 31 has an internal thread section 312, and the lower water inlet 313 is opened within the internal thread section 312. By means of the threaded fit between the internal thread section 312 and the external thread section 512, the lower end of the screw cap 51 can be fixedly connected to the water replenishing tank body 31. Threaded connection not only ensures the tight connection between the screw cap 51 and the water replenishing tank body 31, but also greatly enhances the stability and sealing performance of the overall structure. The mutual cooperation between the internal thread section 312 and the external thread section 512 not only facilitates the installation and disassembly operations of users, but also effectively prevents the water leakage problem caused by loose connection. Such a design is not only beautiful and practical, but also provides users with a convenient and safe usage experience.

[0037] In the embodiment of the present application, the first sealing ring 52 abuts against the upper end surface of the water replenishing tank body 31, effectively sealing the upper end surface of the water replenishing tank body 31. At the same time, the second sealing ring 53 tightly abuts against the upper water inlet 311, ensuring the tight closure of the upper water inlet 311, and further guaranteeing the sealing performance inside the water replenishing tank body 31. Through the cooperative action of the first sealing ring 52 and the second sealing ring 53, a firm and reliable sealing effect between the screw cap 51 and the water replenishing tank body 31 is achieved.

[0038] As Figure 5 shown, the screw cap 51 has a convex ring portion 513, which protrudes from the lower surface of the screw cap 51 and is located outside the connecting shaft 511. An inner first annular groove 514 is provided on the inner side of the convex ring portion 513 and is flush with the lower surface of the screw cap 51. The top of the first sealing ring 52 has a protruding portion 521. The top end surface of the first sealing ring 52 abuts against the convex ring portion 513, and the protruding portion 521 is perfectly adapted to the first annular groove 514, ensuring the tight combination of the sealing ring and the screw cap.

[0039] The lower end of the first sealing ring 52 has an annular convex lip 522, and the annular convex lip 522 abuts against the upper end surface of the water replenishing tank body 31. The convex ring portion 513 and the first annular groove 514 are in concave-convex fit, and by the top of the first sealing ring 52 abutting against the convex ring portion 513, a reliable seal between the lower end of the screw cap 51 and the connecting shaft 511 is achieved. At the same time, the annular convex lip 522 abuts against the upper surface of the water replenishing tank body 31 in a wavy shape, achieving a firm seal between the lower end of the screw cap 51 and the upper surface of the water replenishing tank body 31. Therefore, by arranging the first sealing ring 52 on the connecting shaft 511 and between the screw cap 51 and the upper end of the water replenishing tank body 31, the top of the upper water inlet 311 can be fully sealed.

[0040] As Figure 5 and Figure 6As shown in the figure, a second annular groove 515 is provided at the lower end of the connecting shaft 511. The second sealing ring 53 is sleeved on the second annular groove 515. The second sealing ring 53 has a main sealing lip 531 and a secondary sealing lip 532 extending outward. Both the main sealing lip 531 and the secondary sealing lip 532 abut against the inner wall of the upper water inlet 311. The main sealing lip 531 and the secondary sealing lip 532 are spaced up and down, realizing double radial sealing at the upper water inlet 311, thus ensuring a reliable sealing effect between the upper water inlet 311 and the connecting shaft 511.

[0041] In summary, in this application, the first sealing ring 52 realizes the sealing between the screw cap 51 and the upper end of the water replenishing tank body 31, and the second sealing ring 53 realizes the sealing between the connecting shaft 511 and the inside of the water replenishing tank body 31. The first sealing ring 52 and the second sealing ring 53 cooperate with each other, which can fully improve the sealing effect of the water replenishing tank body 31. When installing the screw cap 51, it is necessary to rotate the screw cap 51 to fix it at the water inlet. When rotating the screw cap 51, the annular convex lip 522 is squeezed, so that the annular convex lip 522 can be more tightly attached to the upper surface of the water replenishing tank body 31, so the sealing effect is very good.

[0042] As Figure 1 and Figure 2 As shown in the figure, this embodiment also provides a humidifier, which includes a water tank sealing structure 5, and also includes a housing 1 and a filter net 12, a fan 15, a wet curtain 13 and a spray pipe 4 arranged in the housing 1. A front window 11 is provided at the right end of the housing 1. The filter net 12 is installed at the front window 11. The filter net 12 can protect the housing 1 from dust and insects. The communication hole 34 is located on the side of the housing 1 away from the front window 11; a water tank 3 is provided at the lower end of the housing 1, and a communication hole 34 communicating with the water replenishing tank body 31 is provided on the left side wall of the water tank 3; the wet curtain 13 is located between the filter net 12 and the fan 15, and the wet curtain 13 is close to the filter net 12; the spray pipe 4 is connected between the water tank 3 and the wet curtain 13.

[0043] Among them, a water supply pipe 33 is connected through the spray pipe 4. The lower end of the water supply pipe 33 extends into the water tank 3 from the housing 1, and a water pump 32 is installed at the lower end of the water supply pipe 33 to pump the water in the water tank 3 upward.

[0044] Preferably, a plurality of spray heads 41 are arranged at intervals at the lower end of the spray pipe 4. When the plurality of spray heads 41 work simultaneously, the wet curtain 13 can absorb water more evenly.

[0045] In the embodiment of the present application, an upper connecting seat 131 and a lower connecting seat 132 are oppositely arranged up and down on the housing 1. The wet curtain 13 is fixed between the upper connecting seat 131 and the lower connecting seat 132, thereby realizing the connection between the wet curtain 13 and the housing 1. Specifically, a water guide groove 1311 is connected through the upper connecting seat 131, and the spray head 41 extends into the water guide groove 1311, so that the spray head 41 can supply water to the wet curtain 13.

[0046] As Figure 3 shown, a collection tank 14 is arranged below the wet curtain 13. A water outlet 1321 is opened on the lower connecting seat 132. The collection tank 14 is located below the water outlet 1321. A downcomer 141 is arranged at the bottom of the collection tank 14. The downcomer 141 passes through the bottom of the housing 1 and is connected to the water tank 3.

[0047] Preferably, an exhaust pipe 2 is further arranged on the housing 1. The exhaust pipe 2 is close to the fan 15. One end of the exhaust pipe 2 has an exhaust port 21, and the other end has an air inlet 22. The air inlet 22 is close to the fan 15. The exhaust port 21 is close to the outside of the housing 1. The size of the air inlet 22 is larger than the size of the exhaust port 21, so that the condensed air can quickly enter the air inlet 22.

[0048] Working principle: The water pump 32 is started, and water is supplied to the spray pipe 4 through the upper water pipe 33. The water in the spray pipe 4 is sprayed on the wet curtain 13 through the spray head 41 to wet the wet curtain 13. The fan 15 is started, and the dry air outside the housing 1 is sucked into the housing 1 through the filter net 12. When the dry air enters the wet curtain 13, it will carry away the water molecules on the wet curtain 13, so that the dry air becomes condensed air after passing through the wet curtain 13. Since only the exhaust pipe 2 is communicated with the outside of the housing 1 except for the front window 11 on the housing 1, the condensed air will be discharged outward through the exhaust pipe 2, thereby increasing the humidity in the environment outside the housing 1. When there is too much water on the wet curtain 13, the water will drip downward into the collection tank 14 and then return to the water tank 3 through the downcomer 141, which can avoid water waste. In summary, the present application is not only convenient to use and has a good humidifying effect, but also the blown condensed air will not cause the tabletop to get wet, so the practicability is better.

[0049] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the embodiments of the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
