[0028] Reference Figures 1 to 5 In some embodiments, the utility model discloses a push-type drainer, which includes:
[0029] Ginseng Figure 1 Combination Figure 2 The sewer pipe 100 is generally cylindrical.
[0030] Continue to refer to Figure 2 The pressing assembly 200 is shown as being arranged inside the sewer pipe 100. The pressing assembly 200 is located near an opening at one end of the sewer pipe 100. An opening is provided at the upper end of the sewer pipe 100. The upper opening of the sewer pipe 100 is arranged near a wash basin for cooperative installation. The water in the wash basin is drained through the upper opening.
[0031] Continue to refer to Figure 2 As shown, the pressing assembly 200 includes a fixing member 210 , a pressing column 220 , a spring 230 , a connecting hook 240 and a first sealing ring 250 .
[0032] Reference Figure 2 The specific structure is that the first groove is arranged on the periphery of the pressing column 220, the first sealing ring 250 is arranged in the first groove, the fixing part 210 is arranged in the sewer pipe 100, the outer wall of the fixing part 210 and the outer wall of the first sealing ring 250 are abutted against the inner wall of the sewer pipe 100, the fixing part 210 is tightly connected and matched with the sewer pipe 100 through the first sealing ring and installed in coordination, as long as the fixing part is assembled at the factory to ensure its centrality, the connection between the fixing part and the sewer pipe is not easy to loosen.
[0033] Continue to refer to Figure 2As shown, a pressing channel 222 is provided in the middle of the pressing column 220, and the pressing column 220 and the spring 230 are sequentially arranged in the pressing channel 222 from top to bottom. A guide groove 2000 is provided on the pressing column 220, and the two ends of the connecting hook 240 are respectively connected to the guide groove 2000 and the bottom of the fixing member 210, and a water flow channel is provided between the inner wall of the sewer pipe 100 and the pressing column 220. The cover body 300 is sleeved on the top of the pressing column 220, and the pressing column is stretched and shortened up and down in coordination with the spring, thereby adjusting the upper end drain port of the sewer pipe 100. The side wall of the cover body 300 is provided with a second sealing ring 310, and the second sealing ring 310 is in contact with or separated from the inner wall of the sewer pipe 100. Refer to Figure 2 Combination Figure 5 As shown, when the upper end of the connecting hook 240 is located at the upper end of the guide groove 2000, the cover body 300 connected to the pressing column 220 is higher than the upper opening of the sewer pipe 100, and the water in the wash basin is drained along the water flow channel from the gap between the pressing column and the cover body. When the user presses the cover body, the pressing column 220 overcomes the resistance of the spring 230 and forces the upper end of the connecting hook 240 to be located at the lower end of the guide groove 2000. At this time, the cover body 300 is flush with the upper opening of the sewer pipe 100 and closed. In addition, the second sealing ring 310 and the inner wall of the sewer pipe 100 contact each other to form a water seal. The water in the wash basin is difficult to flow out from the second sealing ring 310 and the inner wall of the sewer pipe 100, thereby effectively increasing the sealing performance of the drain.

[0036] Continue to refer to Figure 2As shown, the side wall of the fixing member 210 is provided with a first through hole 212, and the side wall of the pressing column 220 is provided with a first limiting groove 213. The first through hole 212 is inserted with a limiting column and cooperates with the first limiting groove 213. The structure of the limiting groove cooperates with the limiting column to ensure that the fixing member and the pressing column 220 do not deviate in the up and down stroke, and water can enter the limiting groove during drainage, so that the side walls of the pressing column 220 and the side walls of the fixing member 210 can accommodate moisture, thereby reducing the friction between the two components and effectively increasing the service life of the components.
[0037] Continue to refer to Figures 1 to 3 As shown, the top of the sewer pipe 100 extends outward with an outer edge 110, and the outer edge 110 covers the stainless steel edging 400. The area of the stainless steel edging covers the outer edge, so that the surface area of the entire drain is larger. The middle side wall of the cover body 300 is provided with a second groove 320. Further, referring to Figure 2 Combination Figure 3 As shown, the second sealing ring 310 includes a mounting portion 311 arranged from the inside to the outside and a sealing portion 312 integrally formed with the mounting portion 311, the size of the mounting portion 311 matches the size of the second groove 320, the thickness of the sealing portion 312 is less than the thickness of the sealing portion 312, and the sealing portion 312 is in contact with or separated from the inner wall of the sewer pipe 100. The sealing portion with a smaller thickness has a higher degree of deformation, and has better sealing performance when deforming in coordination with the inner wall of the sewer pipe 100.
[0038] Continue to refer to Figure 2 Combination Figure 5 As shown, a second through hole 214 is opened at the bottom of the fixing member 210, and the second through hole 214 is connected to the pressing channel 222, wherein the bent portion at one end of the spring 230 is inserted into the bottom side wall of the fixing member 210, and the spring 230 body passes through the second through hole 214 and the pressing channel 222, and the bent portion at the other end of the spring 230 is inserted into the side wall of the guide rail groove 2000, and the bottom opening there can be connected to the air of the sewer pipe 100, so that the user needs to press less force, thereby increasing the user experience.
[0039] Reference Figure 3The path design method is that the guide rail groove 2000 includes a first bending path 2100 and a second bending path 2200 arranged on the side wall of the pressing column 220. The first end and the second end of the first bending path 2100 and the second bending path 2200 are respectively distributed up and down and intersect each other.

When the user presses, one end of the connecting hook 240 passes through the first inclined surface 2310 and the second step 2410 from the first recess 2300, is blocked in the second recess 2400 by the second step 2410, and then the connecting hook 240 is pressed to pass through the second bending path 2200 on the second inclined surface 2420 and the first step 2320 back to the first recess 2300, and is blocked in the first recess 2300 by the first step 2320. The bending path of the inclined surface and the step structure makes the pressing structure transition smoothly and effectively locks the connecting hook.
[0040] In some embodiments, the middle path portions of the first curved paths 2100 are connected by inclined planes, and the middle path portions of the second curved paths 2200 are connected by steps.
