Technical Field
[0001] This utility model relates to the technical field of washbasin drain structure, specifically a washbasin drain structure that is easy to clean. Background Technology
[0002] The basin drain structure refers to the device installed at the drain hole at the bottom of the washbasin, used to connect the basin to the drainage pipe inside the wall or on the ground, so as to achieve smooth drainage, prevent odor backflow, optionally prevent overflow, and facilitate cleaning and maintenance.
[0003] Existing washbasin drain systems mostly use threaded connections for pipe installation. After manual tightening, these connections may loosen with daily use, causing the pipe to fall out and wastewater to drain into the basin, making internal cleaning inconvenient. Therefore, a washbasin drain system that is easy to clean is needed to meet people's needs. Utility Model Content

[0012] Preferably, the filter cover is installed at the bottom opening of the water storage tank by a fixing block.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] (1) By setting a first threaded sleeve and a second threaded sleeve, and by installing a connecting pipe at the bottom of the fixed pipe, the entire drainage system inside the basin body can be disassembled. By pulling the two limiting pieces on the side of the second threaded sleeve upward, the spring is compressed and the guide post slides in the guide groove. The bottom of the limiting piece separates from the limiting groove in the first threaded sleeve, thus canceling the limitation on the first threaded sleeve. At this time, the first threaded sleeve can be rotated to separate from the second threaded sleeve. The limiting piece limits the first threaded sleeve and the second threaded sleeve after installation, which can prevent the connection from loosening and improve the applicability of the connecting pipe.
[0015] (2) By setting up drainage holes and overflow pipes, the water can be discharged when the water reaches a certain height. The inclined setting of the overflow pipe can also reduce the accumulation of dirt inside. The water guide groove on the top of the basin body can guide the water on the countertop, so that the wastewater will not stay on the basin body for a long time and form sediment, making it easy for operators to clean. The filter cover and the leak hole can block large debris and prevent the connecting pipe from being blocked, thus improving the applicability of the basin body. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Example 1: Please refer to Figure 1-5 This utility model provides a technical solution: a washbasin drain structure that is easy to clean, including a washbasin body 1, a water guide groove 3 on the top of the washbasin body 1, a water storage tank 4 inside the washbasin body 1, a fixing pipe 12 installed at the bottom of the washbasin body 1, an auxiliary mechanism 2 at the bottom of the fixing pipe 12, the auxiliary mechanism 2 including a connecting pipe 21 installed at the bottom of the washbasin body 1, a first threaded sleeve 22 installed on the side of the connecting pipe 21, a second threaded sleeve 23 installed on the side of the fixing pipe 12, a limiting groove 24 opened in the first threaded sleeve 22 and the second threaded sleeve 23, a plurality of guide posts 25 installed in the second threaded sleeve 23, a spring 26 sleeved on the side of the guide post 25, a limiting piece 27 slidably installed in the limiting groove 24, a guide groove 28 opened in the limiting piece 27, the guide post 25 and the guide groove 28 are adapted to each other, one end of the spring 26 is installed on the second threaded sleeve 23, and the other end of the spring 26 is installed on the limiting piece 27. One end of the limiting piece 27 extends beyond the side of the first threaded sleeve 22, and the bottom of the guide post 25 is installed in the guide groove 28. When the basin body 1 needs to be cleaned, by pulling the two limiting pieces 27 on the side of the second threaded sleeve 23 to slide in the limiting groove 24, the two springs 26 are compressed, and the guide post 25 slides in the guide groove 28. The bottom of the limiting piece 27 separates from the limiting groove 24, and the limiting of the first threaded sleeve 22 is removed. At this time, the threaded connection between the first threaded sleeve 22 and the second threaded sleeve 23 can be rotated to separate the connecting pipe 21 from the fixed pipe 12, which facilitates the cleaning of the inner wall of the fixed pipe 12 and the connecting pipe 21. Disassembly can be completed without the aid of any tools, which improves the work efficiency of the operator. Through the limiting piece 27 between the first threaded sleeve 22 and the second threaded sleeve 23, there will be no rotation after installation, which will cause the connection to loosen, thereby improving the applicability of the connecting pipe 21.
[0024] Example 2: As Figure 2 and 4 As shown, a faucet 5 is installed on the top of the basin body 1, a drain hole 6 is provided on the side of the water storage tank 4, an overflow pipe 7 is installed on the outer wall of the water storage tank 4, the other end of the overflow pipe 7 is connected to the connecting pipe 21, a drain channel 11 is provided inside the overflow pipe 7, a filter cover 8 is installed at the bottom of the water storage tank 4, a plurality of leakage holes 9 are provided inside the filter cover 8, a fixing block 10 is installed on the side of the filter cover 8, the bottom opening of the water storage tank 4 is adapted to the fixing pipe 12, one end of the fixing block 10 extends beyond the bottom opening of the water storage tank 4, the filter cover 8 is installed at the bottom opening of the water storage tank 4 through the fixing block 10, and the filter cover 8 is installed at the bottom opening of the water storage tank 4 through the fixing block 10. Multiple drain holes 6 are provided with overflow pipes 7 installed on the sides. When the water reaches a certain height, it can be discharged from the drain holes 6. The inclined design of the overflow pipes 7 can also reduce the accumulation of dirt inside. The water guide groove 3 on the top of the basin body 1 guides the water on the countertop, preventing wastewater from staying on the basin body 1 for a long time and forming sediment, making it easier for operators to clean. When the water is drained, large debris is blocked by the filter cover 8 and the drain hole 9 to prevent the connecting pipe 21 from being blocked. Operators can pull the fixing block 10 to remove the filter cover 8 for cleaning. The remaining features are the same as in embodiment 1.
[0025] The working principle is as follows: When cleaning the main body 1 of the basin is required, by pulling the two limiting pieces 27 on the side of the second threaded sleeve 23 to slide within the limiting groove 24, the two springs 26 are compressed, and the guide post 25 slides within the guide groove 28. The bottom of the limiting piece 27 separates from the limiting groove 24, releasing the limiting effect on the first threaded sleeve 22. At this time, the threaded connection between the first threaded sleeve 22 and the second threaded sleeve 23 can be rotated to separate the connecting pipe 21 from the fixed pipe 12, thus facilitating the cleaning of the inner walls of the fixed pipe 12 and the connecting pipe 21. Disassembly can be completed without any tools, improving the operator's work efficiency. The limiting piece 27 between the pipes will not rotate after installation, thus preventing the connection from becoming loose and improving the applicability of the connecting pipe 21. By installing the overflow pipe 7 on the side of the multiple drain holes 6, water can be discharged from the drain holes 6 when the water reaches a certain height. The inclined setting of the overflow pipe 7 can also reduce the accumulation of dirt inside. The water guide groove 3 on the top of the basin body 1 guides the water on the countertop, preventing wastewater from staying on the basin body 1 for a long time and forming sediment, making it easy for operators to clean. When the water is drained, large debris is blocked by the filter cover 8 and the drain hole 9 to prevent the connecting pipe 21 from becoming blocked. Operators can pull the fixing block 10 to remove the filter cover 8 for cleaning.
[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
