AI Technical Summary
The existing bouncing drainer cannot be installed because it needs to be connected to the cover, and lacks the function of slag filtering, so it cannot filter the water when switching between water storage and drainage.
A drainer structure is designed, including a filter mesh, a support frame, a bounce core and a driving rod. By pressing the driving rod to control the movement of the seal, the lower end opening of the filter mesh is opened and closed, so as to realize the filtration and drainage of water, the filter mesh and the pipe. The sealing ring is used to prevent the filter from entering the sewer pipe and realize the filtering function.
The water filtering function is achieved without adding an additional basket. The water is filtered through the filter when the bathtub, sink, and washbasin sewers are drained. When storing water, the sealing member closes the lower end of the filter to ensure that the water is not discharged and is convenient to clean up impurities.

[0026] like Figure 1-Figure 7 As shown: a drain structure, including a filter 1, a support frame 2 is provided at the upper end of the filter 1, a through hole 3 is opened at the middle end of the support frame 2, and a bouncing core 4 is provided on the inner side of the filter 1, a driving rod 41 extending out of the through hole 3 is provided at the upper end of the bouncing core 4, and a sealing member 42 is provided at the lower end of the bouncing core 4. By pressing the driving rod 41, the sealing member 42 can be controlled to move up and down to open and close the lower end opening of the filter 1, and a pipeline sealing ring 5 is provided at the lower end of the filter 1. There is a water flow gap 6 between the filter 1 and the pipeline. Specifically, the lower end of the filter The pipe sealing ring arranged at the bottom abuts against the pipe wall of the sewer pipe. When the bathtub, sink and washbasin are filled with water, the seal seals the lower opening of the filter, and the water in the bathtub, sink and washbasin cannot be discharged. When drainage is required, just press the driving rod, and the driving rod controls the seal to move downward to open the lower opening of the filter. In this way, water will enter the sewer pipe, and the water will enter the filter from the water flow gap outside the filter, and then be discharged from the lower opening of the filter. Impurities will be filtered by the filter, and some impurities will remain in the water flow gap. When cleaning is needed, just pull out the drain as a whole, so that the impurities can be taken out together.
[0027] In the above-mentioned drain structure, a bracket 11 is arranged between the filter 1 and the bouncing core 4, and the bouncing core 4 and the bracket 11 are connected by interference fit or threaded connection. Specifically, the bracket is fixed in the filter, and the bracket bouncing core and the bracket are preferably connected by threads, which is for the convenience of later maintenance.

Specifically, this is to facilitate the installation of the pipe sealing ring in the annular groove and also to facilitate later replacement.
[0032] In the above-mentioned water discharger structure, a driving cap 43 is screwed on the driving rod 41, and the driving cap 43 is gap-matched with the through hole 3 of the support frame 2. Specifically, this is to facilitate the up and down movement of the driving cap, and also to prevent impurities from being directly discharged into the sewer pipe from the gap between the driving cap and the through hole of the support frame; the bouncing core 4 includes a bouncing base 401, a bouncing shell 402, a bouncing shaft 403 and a spring 404, the bouncing shell is connected to the bouncing base by a threaded connection, the bouncing shaft is located in the bouncing shell, the spring is located in the bouncing shell, and its two ends are respectively abutted on the bouncing shaft and the bouncing base, a plurality of active bevel teeth 405 are arranged on the outer side of the driving rod, and a plurality of active bevel teeth 405 are arranged on the outer side of the bouncing shaft for use with the active bevel teeth 405 The driven bevel gear 406 and the part of the bouncing shaft are located in the driving rod, and a plurality of guide bars 407 are arranged in the bouncing shell. The driving rod and the bouncing shaft are provided with slide grooves 408 used in conjunction with the guide bars 407. By pressing the driving rod, the position between the active bevel gear and the driven bevel gear on the driving rod will change. The seal is connected to the jumping shaft, and the spring sleeve is arranged on the connecting rod between the seal and the jumping shaft. When pressed for the first time, the active bevel gear on the driving rod pushes the jumping shaft to move downward, and the driven bevel gear of the jumping shaft will be stuck on the guide bar. At this time, the seal opens the lower end opening of the filter. When pressed for the second time, the active bevel gear of the driving rod moves downward again, controlling the driven bevel gear of the jumping shaft to disengage from the guide bar. The jumping shaft returns to its original position through the spring, and the seal closes the lower end opening of the filter.
[0033] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
