Description

Technical Field

[0001] The utility model belongs to the technical field of kitchen and bathroom accessories and relates to a drain deodorizing plug. Background Art

[0002] Some kitchen and bathroom appliances, such as washing machines, sinks, basins, or mop pools, require drain hoses connected to the sewer pipe to discharge wastewater generated during use. Because wastewater in sewer pipes can backflow and contaminate, it's common practice to install drain plugs. These utilize flap-type deodorizers to prevent backflow, while also preventing odors and mosquitoes.

[0003] Drain odor preventer plugs are generally connected to drain pipes using soft rubber sleeves, but this connection method is not reliable. Since there is no locking and holding function, when there is negative pressure in the pipe, it is easy to cause the drain odor preventer plug to fall out of the drain pipe. Utility Model Content

[0022] The present invention will be further described below with reference to specific embodiments of the present invention. Figure 1-5 :

[0023] A sewer deodorizing plug comprises a main body 1, an outer sealing ring 2 is provided on the outside of the main body 1 for connecting the sewer pipe and the outer wall of the main body 1, an inner sealing ring 3 is provided on the inside of the main body 1 for connecting the inner wall of the main body 1 and the drainage hose, a sliding sleeve of the main body 1 above the outer sealing ring 2 is provided with a clamping ring 4, and a locking ring 5 is threadedly connected, and the locking ring 5 compresses the inner sealing ring 3 when tightened downward, and at the same time drives the clamping ring 4 to move downward and compress the outer sealing ring 2.

[0024] Compare with Figure 1 To the attached Figure 3 The locking method of this embodiment is: put the sewer deodorizing plug into the sewer pipe, put the drain hose into the sewer deodorizing plug to form a preliminary connection, and then tighten the locking ring 5, the locking ring 5 moves downward, because the bottom of the locking ring 5 conflicts with the bottom of the compression ring 4, the locking ring 5 moves downward and drives the compression ring 4 to move downward at the same time. After the compression ring 4 moves downward, it compresses the outer sealing ring 2, causing it to deform and increase, and hold the sewer pipe tightly. On the other hand, when the locking ring 5 moves downward, it will also compress the inner sealing ring 3, causing it to deform and increase, and hold the drain hose tightly, finally forming a double locking structure.

[0025] In order to obtain a better locking and sealing effect, a plurality of circumferential outer sealing lips 6 are provided on the outer wall of the outer sealing ring 2, and the outer sealing lips 6 are in contact with and sealed against the inner wall of the sewer pipe. A plurality of circumferential inner sealing lips 7 are provided on the inner wall of the inner sealing ring 3, and the inner sealing lips 7 are in contact with and sealed against the outer wall of the drainage hose.

[0026] Compare with Figure 2 and attached Figure 4 The main body 1 is provided with an outer mounting groove 8 corresponding to the outer sealing ring 2, and the bottom of the outer mounting groove 8 is provided with a limiting convex ring 9 that abuts against the bottom of the outer sealing ring 2 to limit the position. The limiting convex ring 9 can ensure that the axial position of the lower end face of the outer sealing ring 2 remains unchanged during compression; the height of the outer mounting groove is equivalent to the axial dimension of the outer sealing ring 2 when it is not compressed.

[0027] Compare with Figure 5An elastic card block 10 is provided at the bottom of the above-mentioned clamping ring 4, and the elastic card block 10 forms a limiting structure with the top of the outer mounting groove 8; in this embodiment, the elastic card block 10 is formed on the clamping ring 4 through a separation groove with a lower opening. During the process of inserting the clamping ring 4 downward, the elastic card block 10 produces an outward elastic deformation, and after insertion, the elastic deformation recovers to form an axially limited clamping structure.

[0028] Compare with Figure 2 , Attachment Figure 4 and attached Figure 5 A plurality of positioning posts 11 are arranged on the outer wall of the main body 1 at intervals along the circumferential direction, and a plurality of lower opening positioning grooves 12 cooperating with the positioning posts 11 are arranged on the inner wall of the clamping ring 4. The positioning posts 11 slide axially relative to the positioning grooves 12 and form a circumferential and axial limiting structure. By setting the above-mentioned circumferential limiting structure, it can be ensured that the clamping ring 4 does not rotate, and the locking ring 5 can stably drive the clamping ring 4 to move downward.

[0029] Compare with Figure 2 and attached Figure 3 The above-mentioned inner sealing ring 3 includes an upper cylindrical portion and a lower conical portion. The radial dimension of the lower conical portion gradually decreases from top to bottom and the maximum radial dimension is not greater than the radial dimension of the upper cylindrical portion. An inner mounting groove 13 corresponding to the inner sealing ring 3 is provided in the main body 1. By providing the conical portion, the inner sealing ring 3 can be conveniently inserted into the inner cavity of the main body 1.
