Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of water drain, and relates to a bounce type water drain plug. BACKGROUND

[0002] The bottom of a washbasin is provided with a water drain for connecting with a water drain pipe. The water drain is straightly arranged, and a water drain plug is arranged in the water drain in order to store water in the washbasin. For example, a bounce plug disclosed in patent application No. 202122200739.5 is used in cooperation with at least one water drain fixed on the water outlet of different water pools. The bounce plug comprises a shell, a bounce core and a pressing cover. The shell comprises a covering part having an opening corresponding to the water outlet of the water pool and covering the top of the water drain, and an inner part extending downward from the opening and arranged in the water drain. The inner part has a peripheral wall part combined with the covering part and a hollow part combined with the peripheral wall part, and the hollow part has a plurality of water leakage holes. When in use, the bounce plug is arranged in the main body of the water drain, and the pressing cover is pressed to move the bounce core downward to block the opening of the shell and store water in the washbasin. The pressing cover is pressed to move the bounce core upward to open the opening of the shell and drain the water in the washbasin.

[0003] Generally, the drained water contains residues or hair and other impurities. If the impurities are drained into the water drain pipe together with the water, the water drain pipe is easily blocked. Therefore, the above bounce plug is provided with a rib between adjacent water leakage holes, and the rib can block the impurities in the water flow, so that the shell has a filtering function. However, after a long time of use, the filtered impurities need to be cleaned, otherwise the water leakage holes are blocked due to the accumulation of impurities, causing poor water drainage. The impurities are blocked in the shell, and the bounce core is connected in the shell. That is, the bounce core must be disassembled to clean the impurities. However, the bounce core is usually connected by threads, the pressing cover is usually a round cover, and the bounce core is usually screwed tightly to ensure the reliability of use, which makes the operation of the user not very convenient. UTILITY MODEL CONTENTS

[0004] The utility model aims at the above problems existing in the prior art, and provides a bounce type water drain plug, which solves the problem that the impurities are not easy to clean while having a filtering function.

[0005] The utility model can be realized by the following technical scheme.

[0006] The utility model provides a bounce type sewer plug, which comprises a body in the shape of an open-ended cylinder and a bounce sealing assembly connected to the body, the outer side of the upper end of the body is provided with an annular shoulder, the lower end of the body has a water outlet communicating with the inside of the body, and the utility model further comprises a filter body in the shape of an open-ended cylinder, the filter body is sleeved on the outside of the body, the water outlet is located in the filter body, the side and / or bottom of the filter body has a filter hole, and the filter body is provided with elastic positioning structures in concave-convex matching with the body.

[0007] In use, the bounce type sewer plug is directly placed into the main body of a sewer connected to the bottom of a washbasin, and the annular shoulder at the upper end of the body abuts against the upper end of the main body of the sewer. When the washbasin needs to store water, a user operates the bounce sealing assembly to close the upper end of the body, so that water cannot flow into the body. When the washbasin needs to drain water, the user operates the bounce sealing assembly again to open the upper end of the body, and the water in the washbasin flows into the body and then flows out through the water outlet and is finally drained into the main body of the sewer.

[0008] The bounce type sewer plug is provided with the filter body in the shape of an open-ended cylinder connected to the outside of the body, the side and / or bottom of the filter body has a filter hole, and the water outlet of the body is located in the filter body, so that water must pass through the filter body before being drained into the main body of the sewer from the body, and food residues or sundries such as human hair flowing down with the water can be blocked by the filter body, thereby avoiding the blockage of the sewer pipe. After being used for a long time, the bounce type sewer plug is taken out of the main body of the sewer, the filter body is directly pulled off the body, and the sundries intercepted in the filter body can be cleaned. After cleaning, the filter body is sleeved on the outside of the body again, and the two are connected together by the elastic positioning structures. The water outlet only serves to pass water and does not have a filtering function, and the filtering is completely realized by the filter body, so that the bounce sealing assembly does not need to be disassembled when the sundries are cleaned, and the filter body only needs to be pulled off, which is very convenient to operate.

[0009] In the above bounce type sewer plug, the elastic positioning structures comprise a plurality of positioning elastic pieces and a plurality of grooves arranged on the outside of the body in the circumferential direction, the positioning elastic pieces are in the shape of a strip in the vertical direction, one end of each positioning elastic piece is fixedly connected to the filter body, the middle part of each positioning elastic piece in the vertical direction is bent towards the center line of the filter body, and the bent part of each positioning elastic piece is respectively clamped in each groove.

[0010] The positioning elastic sheet is strip-shaped along the vertical direction, and the middle part of the positioning elastic sheet along the vertical direction is bent towards the center line of the water filtering body, so that the positioning elastic sheet is actually >-shaped. On this basis, one end of the positioning elastic sheet is fixedly connected with the water filtering body, and the other end of the positioning elastic sheet is in a suspended state, so that the positioning elastic sheet is elastic. When the upper end of the water filtering body is sleeved outside the body, the outer wall of the body extrudes the bent part of the positioning elastic sheet outward. After the bent part of the positioning elastic sheet corresponds to the position of the groove, the positioning elastic sheet resets under the action of its own elastic force and makes the bent part clamped into the groove, so that the water filtering body and the body are positioned together.

[0011] When the water filtering body needs to be disassembled, the water filtering body is only pulled out. Because the lower groove wall of the groove is fixed, the lower groove wall of the groove extrudes the positioning elastic sheet during the pulling-out process of the water filtering body, so that the positioning elastic sheet deforms outward of the groove and protrudes from the groove. In this way, the water filtering body and the body are disconnected.

[0012] In the above-mentioned bounce type drain plug, the water filtering body is a stainless steel part, and the positioning elastic sheet is integrally connected with the water filtering body.

[0013] The water filtering body is a stainless steel part, and the positioning elastic sheet is integrally connected with the water filtering body. That is, the positioning elastic sheet is also made of stainless steel. In this way, when the positioning elastic sheet is weakened due to multiple insertions and extractions of the water filtering body, the user can further bend the positioning elastic sheet to ensure its elasticity.

[0014] In the above-mentioned bounce type drain plug, the water filtering body is provided with a plurality of windows at a position close to the upper end along the circumference, the number of the windows corresponds to the number of the positioning elastic sheets, and each positioning elastic sheet is located in a corresponding window and the lower end of each positioning elastic sheet is connected with the lower side window of the window.

[0015] The positioning elastic sheet is located in the window, so that the user can conveniently adjust the elasticity of the positioning elastic sheet through the window when the elasticity of the positioning elastic sheet is weakened, which is equivalent to a yielding effect. Specifically, in the case that the bent part of the positioning elastic sheet is clamped in the groove, a flathead screwdriver is directly aligned with the window and slightly forced downward to restore the elasticity.

[0016] In the above-mentioned bounce type drain plug, the outer side of the body is higher than the position of the groove and has an annular positioning seat, and the upper end of the water filtering body abuts against the outside of the positioning seat.

[0017] Through the above-mentioned arrangement, the centering effect can be achieved when the water filtering body and the body are connected, so as to ensure that the water filtering body does not tilt or skew.

[0018] In the above-described bounce-type drain plug, as another technical solution, the elastic positioning structure comprises a plurality of elastic protrusions arranged on the inner side wall of the upper end of the filter body in the circumferential direction and corresponding recesses arranged on the outer body, the elastic protrusions are in the shape of a spherical cap, and the recesses are shaped to match the elastic protrusions.

[0019] Compared with the prior art, the bounce-type drain plug connects the filter body in the shape of an open-topped cylinder to the outer body, the side and / or bottom of the filter body has a filter hole, and the water passage of the body is located in the filter body, so that water must first pass through the filter body before being discharged from the body into the main body of the drain, thereby blocking food residues or human hair and other sundries flowing down with the water by means of the filter body, avoiding the blockage of the drain pipe. The water passage is only used for water and does not have a filtering function, and the filtering is completely realized by the filter body. Therefore, when cleaning the sundries, the bounce sealing assembly does not need to be removed, and only the filter body needs to be pulled out, which is very convenient to operate.

[0020] In addition, the body and the filter body are connected by the elastic positioning structure of concave-convex matching, which not only ensures the connection stability between the two under the action of no external force, but also enables the filter body to be easily disassembled for cleaning sundries.
