DETAILED DESCRIPTION

[0033] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0034] The present invention will be further described below with reference to the embodiments.

[0035] Example: Refer to the attached Figure 1 To the attached Figure 8 As shown in the figure, the bathroom floor drain includes a floor drain body, which includes a drain plate 1 and a leakage pipe 2 detachably mounted at the bottom of the drain plate 1 , and a plurality of leakage holes 103 communicating with the leakage pipe 2 are opened in the middle of the drain plate 1 .

[0036] Specifically, it also includes a first support frame 3 fixedly arranged on the top of the inner cavity of the leaking pipe 2, and the first support frame 3 has multiple first leakage ports 302; and a cleaning component 5 movably arranged on the first support frame 3, for cleaning the leakage holes 103 on the leakage plate 1, and the cleaning component 5 includes a support cylinder 501 rotatably arranged in the middle of the support frame, and multiple brushes 502 in contact with the leakage plate 1 are detachably installed on the top of the support cylinder 501, and the multiple brushes 502 are arranged in a circular shape with equal distances. The opening of the support cylinder 501 faces downward and an internal thread 503 is provided on the inner side of the port. By arranging the rotatable brush 502, the floor drain has the function of cleaning the leakage plate 1, thereby reducing the blockage of the leakage hole 103 and facilitating the smooth discharge of water.

[0037] Furthermore, it also includes a second support frame 4 fixedly arranged at the bottom of the inner cavity of the leaking pipe 2, the second support frame 4 has a plurality of second water leakage ports 402, and a driving member 6 movably arranged on the second support frame 4, which is used to drive the support cylinder 501 to rotate, and the driving member 6 includes a water accumulation seat 601 fixed to the inner wall of the middle part of the leaking pipe 2 and having an inner annular surface, and the second support frame 4 is elastically provided with a water accumulation plate 602 that performs a lifting movement along the inner annular surface, the water accumulation plate 602 is located at the top of the inner annular surface, and the outer edge of the water accumulation plate 602 is adapted to slide with the inner wall of the inner annular surface, and a power rod 603 is fixed in the middle position of the water accumulation plate 602, the power rod 603 has an external thread 604, and the power rod 603 is adapted to be threadedly connected with the support cylinder 501 Then, during drainage, water passes through the leakage hole 103 and accumulates on the water accumulation plate 602. As the drainage volume increases, the pressure exerted on the water accumulation plate 602 becomes greater, and the water accumulation plate 602 moves downward. Through the threaded relationship between the power rod 603 and the support tube 501, the support tube 501 rotates and drives the brush 502 to rotate, thereby achieving the purpose of cleaning the leakage plate 1. After the water is discharged, the water accumulation plate 602 moves up, and similarly drives the brush 502 to clean the leakage plate 1 to ensure the discharge of water. Through the cooperation of the above-mentioned structure, during the drainage process, the water's own weight is used as the power, and the leakage plate 1 can be cleaned once in the early and late stages of each drainage, effectively reducing the efficiency of clogging of the leakage hole 103.

[0038] Furthermore, it also includes a sealing member 7 movably arranged at the bottom of the inner cavity of the leaking pipe 2, which is used to block the second water leakage port 402 on the second support frame 4. The sealing member 7 includes a sealing plate 701 in contact with the lower surface of the second support frame 4, and the sealing plate 701 moves up and down synchronously with the water accumulation plate 602 through the guide rod 703. A drain port 702 is provided on the sealing plate 701, and the drain port 702 is arranged at an interval and staggered with the second water leakage port 402. When the water is not discharged through the floor drain, the sealing plate 701 contacts the second support frame 4, and the second water leakage port 402 and the drain port 702 are staggered with each other, which can slightly prevent air from flowing back into the bathroom through the leaking pipe 2, and has a certain anti-odor function. When in use, the water accumulation plate 602 moves downward under the pressure of water, which can drive the sealing plate 701 to separate from the second support frame 4, and the sewage can be discharged smoothly from the second water leakage port 402 and the drain port 702.

[0039] Specifically, the first support frame 3 includes a plurality of support rods 301 fixed in a circular shape and equidistantly on the inner wall of the leaking pipe 2, and a first leakage port 302 is formed between two adjacent support rods 301. The middle part of the support rod 301 has a central support block 303, and the support cylinder 501 is rotatably set on the central support block 303 to support the cleaning part 5, so that the support cylinder 501 and the scrub brush 502 can work normally.

[0040] Specifically, the top of the support tube 501 is annular and equidistantly fixed with multiple mounting brackets 504, the bottom of the scrub brush 502 has a groove, the mounting bracket 504 is fixed in the groove by bolts, the inner wall of the leakage pipe 2 is fixed with an annular support plate 8, and the bottom of the mounting bracket 504 is embedded with a first ball 505, which is rollingly connected to the upper surface of the annular support plate 8, so as to facilitate the disassembly and assembly of the scrub brush 502 and to replace the scrub brush 502 that has been used for a long time and is damaged. By being arranged on the annular support plate 8, the stability of the rotation of the scrub brush 502 can be improved.

[0041] Specifically, the two end openings of the inner ring surface of the water accumulation seat 601 are set to be a frustum with a wide outside and a narrow inside, and the water accumulation plate 602 is set to be a hollow frustum with a narrow top and a wide bottom, so that the sewage can drive the water accumulation plate 602 to move downward, and when the water accumulation plate 602 moves down to separate from the bottom port of the water accumulation seat 601, the sewage can be discharged.

[0042] Specifically, the second support frame 4 is a supporting circular plate 401 fixed to the inner wall of the bottom of the leaking pipe 2, and multiple second leaking ports 402 are arranged in a ring-shaped and equidistant manner on the supporting circular plate 401. The sealing plate 701 is in contact with the lower surface of the supporting circular plate 401. The area of ​​the drain port 702 is not less than the area of ​​the second leaking port 402, which supports the driving member 6. The supporting circular plate 401 seals the drain port 702, and the sealing plate 701 seals the second leaking plate, so that the leaking pipe 2 has a certain anti-odor function.

[0043] Specifically, a plurality of reset springs 605 are evenly fixed between the support circular plate 401 and the water accumulation plate 602, and the guide rod 703 is arranged in the middle of the reset spring 605. The two ends of the guide rod 703 are respectively fixed to the water accumulation plate 602 and the sealing plate 701. A through hole 403 corresponding to the guide rod 703 is provided on the support circular plate 401. The guide rod 703 is arranged in the through hole 403 and is slidably connected to the through hole 403. A limit block 704 is fixed in the middle of one of the guide rods 703. The limit block 704 is fixed to the middle of the guide rod 703. 04 is used to limit the downward movement distance of the water accumulation rod. The water accumulation plate 602 moves vertically up and down under the action of the guide rod 703, which can drive the support cylinder 501 to rotate and clean the leaking plate. At the same time, after the sewage is discharged from the gap between the water accumulation plate 602 and the water accumulation seat 601, under the action of the reset spring 605, the water accumulation plate 602 moves vertically upward, and similarly drives the support cylinder 501 and the brush 502 to clean the leaking plate, and the sealing plate 701 moves up with the guide rod 703 and blocks the second leakage port 402.

[0044] Furthermore, it also includes a lubricating member 9 arranged at the top of the inner cavity of the leaking pipe 2, which plays a lubricating role for the power rod 603 and the support tube 501, including a water guide rod 901 fixed to the outer wall of the support tube 501, a water guide groove 902 is provided on the water guide rod 901, and a water guide port 903 connected to the water guide groove 902 is provided on the support tube 501.

When the sewage initially flows into the leaking pipe 2, the sewage (a mixture of shampoo or shower gel and water) dripping into the water guide groove 902 falls into the support tube 501 through the water guide port 903, and flows between the external thread 604 and the internal thread 503 through the basin groove 907, the water inlet 905 and the lubrication groove 906, which plays a certain lubricating role on the support tube 501 and the power rod 603, making the rotation of the scrub brush 502 more stable.

[0045] Furthermore, the outer edge of the leakage pipe 2 has an annular mounting plate 201, and a group of mounting holes 202 are arranged in an annular shape and equidistantly on the annular mounting plate 201. The bottom edge of the leakage plate 1 is fixed with an elastic clamping column 101 corresponding to the mounting hole 202. The elastic clamping column 101 is clamped in the mounting hole 202, which facilitates the disassembly and assembly of the leakage plate 1 and the leakage pipe 2. The middle part of the leakage plate 1 has an annular protrusion 102 to prevent water from accumulating in the middle part of the leakage plate 1.
