[0028] In one embodiment of the present invention, reference Figure 1-5, a drainage assembly 100 is provided, including a box body 10 and a sealing plug 20 , wherein a drainage pipe 14 is arranged at the bottom of the box body 10 .

[0029] In this embodiment, the housing 10 can be any suitable housing of household appliances, such as a housing of a humidifier, a heater or a cooler. The housing 10 can be made of, for example, a plastic material that is harmless to the human body, environmentally friendly and durable. The sealing plug 20 is preferably made of a plastic material with certain elasticity and wear resistance. In this embodiment, the sealing plug 20 is smoothly sealed into the housing 10, such as the drain pipe 14 of the housing 10, so as to prevent the drain pipe 14 from leaking when drainage is not required, that is, to prevent the stored water in the housing 10 from being discharged through the drain pipe 14, thereby dirtying the ground.

[0030] In one embodiment, the top of the inner wall 141 of the drain pipe 14 may form an annular inclined guide wall 144 and an annular sealing edge 142 extending outwardly from the top of the annular inclined guide wall 144. Correspondingly, the sealing plug 20 has a plug body 22, the bottom end of the plug body 22 forms an annular sealing flange 222 extending along the circumferential direction, and the bottom of the annular sealing flange 222 forms an annular inclined guide wall 226. When the entire sealing plug 20 is inserted into the drain pipe 14, the annular sealing flange 222 is tightly inserted into the annular sealing edge 142. In other words, the annular sealing flange 222 is in sealing contact with the surface of the annular sealing edge 142, or it can be said that an interference fit is formed between the two, thereby achieving the anti-leakage effect of the sealing plug 20 on the drain pipe 14. In addition, the smooth inclined guiding fit between the inclined guide wall 144 and the annular inclined guide wall 226 can achieve the technical effect of quickly and conveniently inserting the sealing plug 20 into the drain pipe 14, thereby achieving quick and convenient assembly.

[0031] Preferably, the drain assembly 100 also includes a push-open member 30. The function of the push-open member 30 is: when the drain assembly 100 needs to drain the accumulated water in the box body 10, the external sewer pipe is connected to the drain pipe 14, and then the sewer pipe lifts the push-open member 30, and the push-open member 30 lifts the sealing plug 20 upward relative to the drain pipe 14, thereby releasing the sealing effect of the sealing plug 20 on the drain pipe 14, allowing the accumulated water in the water tank 10 to flow along the annular drainage gap between the drain pipe 14 and the sealing plug 20 and be discharged through the sewer pipe.

[0032] Specifically, according to one embodiment, the push-opening member 30 has a rod body 32, a push plate 38 is fixed to the bottom of the rod body 32; the push-opening member 30 is disposed in the inner wall 141, and the top of the rod body 32 is fixed to the sealing plug 22; a compression spring 40 is sleeved on the rod body 32, and the bottom end of the compression spring 40 elastically presses against the push plate 38. Through the pushing action of the compression spring 40, the top of the rod body 32 is fixedly contacted with the sealing plug 22. When the sewer pipe is connected to the drain pipe 14, the sewer pipe pushes the push plate 38 upward, causing the entire push-open member 30 to move upward, and the annular inclined guide wall 226 fixed to the rod body 32 of the push-open member 30 and the entire sealing plug 22 also move upward for a distance, thereby releasing the sealing contact between the annular sealing flange 222 and the surface of the annular sealing edge 142, and forming an annular drainage gap therebetween, so that the accumulated water in the water tank 10 can be discharged along the annular drainage gap between the drain pipe 14 and the sealing plug 20 and through the sewer pipe.

[0033] Preferably, in order to achieve a fixed connection between the push-open piece 30 and the sealing plug 20, a protrusion 224 can be provided at the top of the plug body 22, and a fixing cavity 2242 is provided in the protrusion 224; a fixing head 34 is formed at the top of the rod body 32; the fixing head 34 is passed through the plug body 22 and is inserted into the fixing cavity 2242, thereby achieving a fixed connection between the push-open piece 30 and the sealing plug 20 through the fixing cooperation of the two.

[0034] In order to achieve a better sealing effect, the following design can be made: the interference fit range between the annular sealing flange 222 and the annular sealing edge 142 is 0.05-0.5 mm. The interference fit amount within this range can ensure a good sealing effect, while the contact between the annular sealing flange 222 and the annular sealing edge 142 will not be too tight, causing one or both parts to fail due to severe deformation.

[0035] As a preferred design, the ratio between the radial length of the annular sealing flange 222 and the width of the annular sealing edge 142 in the inclined direction is in the range of 0.5-2. This ratio range can maintain smooth sealing contact between the annular sealing flange 222 and the annular sealing edge 142 without causing serious deformation of one or both of them to cause component failure, and can also ensure smooth assembly between the sealing plug 20 and the drain pipe 14.

[0036] In one embodiment, the area of ​​the push plate 38 is designed to be larger than the area of ​​the cross section of the rod body 32. This design ensures that the push plate 38 has a sufficient area so as to maintain good contact with the end of the external downpipe as much as possible. The push plate 38 is arranged at the bottom of the inner wall 141, and the push plate 38 is arranged to: when being pushed axially upward, the annular sealing flange 222 is separated from the annular sealing edge 142 to form an annular drainage gap therebetween, so that the accumulated water in the water tank 10 can flow from the annular drainage gap along the inner wall of the drainage pipe 14 to the outside, thereby achieving the effect of draining the waste water in the water tank 10.

[0037] Optionally, an angle is preferably formed between the annular sealing flange 222 and the side wall of the plug body 22, and the angle is an acute angle. Preferably, the acute angle is 45 degrees. This angle design can reduce the resistance when the sealing plug 20 is assembled to the drain pipe 14, thereby achieving smooth assembly of the sealing plug 20. If this angle is too large, it means that the dimension of the annular sealing flange 222 radially extending outward from the circumferential surface of the plug body 22 is too large. The larger the extension, the easier it is for the annular sealing flange 222 to block the drain pipe 14, thereby increasing the difficulty of assembly. Therefore, designing the angle to be within the above-mentioned preferred range can reduce the difficulty of assembly.

[0038] In order to achieve a similar effect of reducing the difficulty of assembly, the thickness of the annular sealing flange 222 can be designed to be 0.4-1 mm. The annular sealing flange 222 within this thickness range has sufficient structural strength and sufficient elastic deformation capacity, so that it can compress the annular sealing edge 142 through appropriate elastic deformation, thereby improving the sealing effect between the two.

Further, other steps, measures, and schemes in the various operations, methods, and processes discussed in this application may also be alternated, altered, rearranged, decomposed, combined, or deleted.

[0040] The above description is only a partial implementation method of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
