[0021] Figure 3 This is a diagram illustrating the pulling of a rope. Detailed Implementation

[0022] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0023] like Figures 1 to 3A hand-operated cleaning floor drain includes a drain body 3, a cover plate 4, a filter screen 5, and a crushing mechanism 6. The drain body 3 has an inlet 7 and an outlet 8 on its upper and lower sides, respectively. The cover plate 4 is installed at the inlet 7 and has filter holes 9. The filter screen 5 is located between the inlet 7 and the outlet 8. The crushing mechanism 6 is located between the cover plate 4 and the filter screen 5. The crushing mechanism 6 includes a cutter head 61, a housing 62, a rotating shaft 63, a pull rope 64, a reversing ring 65, and a return spring 66. The housing 62 is fixed... A fixed connection is made to the lower side of the cover plate 4. The rotating shaft 63 passes through the lower side of the housing 62 and is rotatably connected to the housing 62. The cutter head 61 is installed at the lower end of the rotating shaft 63. The reversing ring 65 is set on one side of the rotating shaft 63 and is fixedly connected to the housing 62. The cover plate 4 is provided with a rope hole above the reversing ring 65. One end of the pull rope 64 is wrapped around the rotating shaft 63, and the other end of the pull rope 64 extends through the reversing ring 65 to the rope hole. Pulling the pull rope 64 drives the rotating shaft 63. The return spring 66 is used to reset the rotating shaft 63.

[0024] With the above setup, the floor drain breaks up debris by pulling the rope 64, making cleaning very convenient. It also requires no electricity, eliminating the need for power supply and wiring, thus improving installation convenience.

[0025] The drain body 3 of this application can refer to the existing drain. The upper water inlet 7 is set on the ground, and the lower water outlet 8 is connected to the drain pipe. The water flow on the ground flows downward through the filter hole 9 of the cover plate 4. After the filter screen 5 filters the water flow, it flows downward from the water outlet 8 and enters the drain pipe. The impurities in the water flow are filtered by the filter screen 5 and are retained on the upper side of the filter screen 5.

[0026] Cover plate 4 is a flat plate structure, specifically circular, installed at inlet 7. The upper side of cover plate 4 is flush with the upper side of drain body 3, thus making the upper side of cover plate 4 flush with the ground. The side of housing 62 is cylindrical, and the ratio of the outer diameter of housing 62 to the diameter of inlet 7 is less than 10%, limiting the size of housing 62 and preventing housing 62 from affecting the drainage speed. The blade 61 is less than 1mm thick, increasing the sharpness of blade 61. Reversing ring 65 is used to switch the pulling direction of pull rope 64. Pulling the upper end of pull rope 64 upward, pull rope 64 through reversing ring 65 to pull shaft 63, and pull rope 64 is released from shaft 63, causing shaft 63 and blade 61 to rotate synchronously. Return spring 66. The blade twists and deforms, breaking the debris on the filter screen 5 into small fragments. After the pull rope 64 is released, the return spring 66 returns to its original position, driving the rotating shaft 63 to rotate in the opposite direction back to its initial position. The rotating shaft 63 rewinds the pull rope 64, repeating this process multiple times to break the debris completely. When water flows through the filter holes 9 into the drain body 3, the broken fragments flow with the water through the filter screen 5 into the drain pipe. In this application, the aperture of the filter screen 5 is between 3mm and 7mm, which prevents larger debris from entering the drain pipe and clogging it, while allowing the broken fragments to pass through, preventing debris from remaining in the drain body 3 and clogging the drain.

[0027] As one implementation, the crushing mechanism 6 also includes a support shaft 67, which is coaxially fixedly connected to the upper end of the rotating shaft 63 and abuts against the upper side of the cover plate 4. A return spring 66 is sleeved on the support shaft 67, with its upper end fixedly connected to the cover plate 4 and its lower end fixedly connected to the rotating shaft 63.

[0028] The above settings improve the stability of the return spring 66 and prevent it from buckling.

[0029] In this application, the rotating shaft 63 is coaxially rotatably connected in the housing 62, and the outer diameter of the support shaft 67 is smaller than the outer diameter of the upper end of the rotating shaft 63. The support shaft 67 is located inside the return spring 66. When the return spring 66 is torsional, the support shaft 67 can support the inside of the return spring 66 and prevent the return spring 66 from experiencing large out-of-plane instability.

[0030] As one implementation, the crushing mechanism 6 also includes a pull ring 68, which includes a base 681 and a ring 682 fixedly connected to the upper side of the base 681. The upper side of the cover plate 4 is provided with a groove 10 that is adapted to the base 681. The base 681 is embedded in the groove 10. The upper side of the base 681 is flush with the upper side of the cover plate 4. The pull rope 64 is fixedly connected to the lower side of the base 681.

[0031] The above settings make it easy to pull the rope 64 via the pull ring 68.

[0032] As one implementation, the housing 62 is located at the center of the cover plate 4, and the water filter hole 9 is located on the outside of the housing 62.

[0033] The above-mentioned design prevents water from entering the casing 62.

[0034] The cover plate 4 of this application is circular, and the housing 62 is installed on the lower side of the center of the cover plate 4. There is no water filter hole 9 on the upper side of the housing 62 to prevent water from the ground from flowing into the housing 62 through the water filter hole 9.

[0035] As one implementation, the bottom of the groove 10 is raised upward in the middle, and an annular water storage tank 11 is provided around the bottom of the groove 10. A flow channel 12 is provided on the cover plate 4. The upper end of the flow channel 12 extends to the annular water storage tank 11, and the lower end of the flow channel 12 penetrates to the lower side of the cover plate 4 and is located on the outside of the shell 62.

[0036] The above-mentioned design prevents water from flowing through the rope hole into the housing 62.

[0037] The rope hole of this application runs through the middle of the bottom of the groove 10. The middle of the bottom of the groove is raised, so that after the water flows into the groove 10, it is not easy to flow into the shell 62 through the rope hole. Moreover, an annular water storage tank 11 is provided at the edge of the groove 10. The water flowing into the groove 10 will flow to the outside of the shell 62 through the annular water storage tank 11 and the flow channel 12.

[0038] As one implementation, the drain also includes a magnet 14 fixedly connected inside the drain body 3. The filter screen 5 includes a mesh plate 51 and a frame 52. The frame 52 is arranged along the inner periphery of the drain body 3 and is adsorbed on the upper side of the magnet 14. The edge of the mesh plate 51 is fixedly connected to the frame 52.

[0039] The above settings facilitate the installation and removal of filter 5.

[0040] The inner side of the drain body of this application is basically cylindrical, the frame 52 is circular, the outer periphery of the frame 52 is basically in contact with the inner side of the drain body, the frame 52 is made of iron and can be attracted to the upper side of the magnet 14, the mesh plate 51 is made of metal and has good strength, and the mesh plate 51 is provided with filter holes, which can allow debris and water to pass through.

[0041] As one implementation method, the upper end of the drain body 3 is fixedly connected with an outwardly extending flange 13.

[0042] The above settings facilitate the installation of floor drains.
