Description

Technical Field

[0001] This utility model relates to the field of drainage, and more specifically to a floor drain. Background Technology

[0002] Floor drains are crucial interfaces connecting the drainage system to the indoor floor in a residence. Their quality directly impacts indoor air quality because the drain pipes and septic tanks are connected to the living space. Existing floor drains typically consist of self-closing silicone tubes. During drainage, gravity forces the closed portion of the silicone tube open, allowing water to drain. When not draining, the lower end of the tube automatically closes to prevent odors from escaping and spreading throughout the room. However, silicone is prone to aging, has a short lifespan, requires frequent replacement, and is costly. Utility Model Content

[0003] This utility model provides a floor drain that ensures odor prevention, extends service life, and reduces costs.

[0004] The technical solution adopted by this utility model to solve the above problems is as follows: A floor drain includes a drain pipe and a ring plate seat fixed to the upper end of the drain pipe. The lower end of the drain pipe is provided with a plug ring, and a float ball is provided inside the drain pipe. The diameter of the float ball is smaller than the inner diameter of the drain pipe and larger than the inner diameter of the plug ring.

[0005] A filter mechanism is installed at the top inside the drain pipe.

[0006] The filtration mechanism includes an insert tube that slides inside the upper end of the drain pipe, a filter plate fixed at the lower end of the insert tube, and a support plate resting on a ring plate seat fixed at the upper end of the insert tube.

[0007] The inner ring of the ring plate seat is provided with a slot for placing a tray.

[0008] It also includes a pick-and-place mechanism for picking up and placing the filter mechanism.

[0009] The picking and placing mechanism is a horizontal bar fixed to the upper end of the inside of the insertion tube.

[0010] The pick-and-place mechanism is a central shaft fixed at the center of the filter plate.

[0011] The central shaft is internally threaded with a screw rod, and a top plate is fixed to the lower end of the screw rod.

[0012] The tray has outwardly extending locking blocks.

[0013] A rubber ring is provided on the outer edge of the ring plate seat.

[0014] The beneficial effects of this utility model are: When draining, the sewage entering the drain pipe will cause the float to rise, thereby opening the plug ring to drain the water. When not draining, the float will automatically fall to the inner ring of the plug ring to seal the plug ring, ensuring odor prevention, long service life, and reduced costs.

[0017] 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.

[0018] The following is combined Figure 1-3 A detailed description of a type of floor drain: A floor drain includes a drain pipe 2 and a ring plate seat 1 fixed to the upper end of the drain pipe 2. The lower end of the drain pipe 2 is provided with a plug ring 3, and a float ball 4 is provided inside the drain pipe 2. The diameter of the float ball 4 is smaller than the inner diameter of the drain pipe 2 and larger than the inner diameter of the plug ring 3.

[0019] In use, the drain pipe 2 is inserted into the drain and installed through the ring plate seat 1. When draining, sewage enters the drain pipe 2 through the ring plate seat 1. The sewage entering the drain pipe 2 will cause the float 4 to float, which will then open the plug ring 3 to drain. After the drainage is completed, the float 4 loses buoyancy and will automatically fall into the inner ring of the plug ring 3 to seal the plug ring 3, ensuring odor prevention, long service life, and reduced cost.

[0020] The outer edge of the ring plate seat 1 is provided with a rubber ring, which enables the ring plate seat 1 to be stably engaged with the drainage point, ensuring the stability of the floor drain.

[0021] Further: A filter mechanism is installed inside the upper part of the drain pipe 2.

[0022] The filtration mechanism includes an insertion tube 6 that slides inside the upper end of the drain pipe 2, a filter plate 7 fixed at the lower end of the insertion tube 6, and a support plate 5 that rests on the ring plate seat 1 fixed at the upper end of the insertion tube 6.

[0023] To prevent debris in the sewage from entering the drain pipe 2 and affecting the float 4, a filtration mechanism is installed. When the sewage flows to the ring plate seat 1 and enters the drain pipe 2, the debris in the sewage will be blocked by the filter plate 7, while the water will enter the drain pipe 2 through the filter holes of the filter plate 7, thereby causing the float 4 to float and ensuring the discharge of sewage. The insertion tube 6 creates a groove at the top of the filter plate 7 to hold and collect debris; the tray 5 is used to mount the filter plate 7.

[0024] Further: By providing a slot for placing the support plate 5 in the inner ring of the ring plate seat 1, the support plate 5 can be placed into the slot when the filter plate 7 is installed, ensuring the flatness of the upper end of the ring plate seat 1 and facilitating the flow of sewage into the drain pipe 2.

[0025] Furthermore, based on the above embodiments: It also includes a pick-and-place mechanism for picking up and placing the filter mechanism.

[0026] The inclusion of a pick-and-place mechanism facilitates the installation or removal of the filter unit and allows for the easy emptying of debris from the filter unit.

[0027] like Figure 4 As shown, one embodiment of the pick-and-place mechanism is as follows: The picking and placing mechanism is a horizontal bar 9 that is fixed laterally inside the upper end of the insertion tube 6.

[0028] The horizontal bar 9 is placed horizontally at the upper end of the inside of the insertion tube 6, making it easy to access the filter mechanism through the horizontal bar 9.

[0029] like Figure 5 As shown, another embodiment of the pick-and-place mechanism is as follows: The pick-and-place mechanism is a central shaft 10 fixed at the center of the filter plate 7.

[0030] The central axis 10 is designed to facilitate the removal of the filter mechanism by pinching or squeezing it.

[0031] Based on this, further: The central shaft 10 is internally threaded with a screw 11, and a top plate 12 is fixed to the lower end of the screw 11.

[0032] Rotating the screw 11 causes it to move axially within the central shaft 10 through its threaded engagement with the central shaft 10. This movement controls the screw 11's axial movement on the filter plate 7, allowing the top plate 12 at the lower end of the screw 11 to press the float 4 firmly against the inner ring of the sealing ring 3. This ensures the sealing of the leaking pipe 2 and prevents the float 4 from being blown up by high air pressure during extreme weather conditions, which could cause foul odors to overflow along the pipe and spread throughout the room.

[0033] Further: A locking block 8 extends outward from the tray 5.

[0034] By setting the locking block 8, which cooperates with the locking groove on the ring plate seat 1, the support plate 5 is prevented from rotating relative to the ring plate seat 1 when the screw 11 is rotated, thus affecting the adjustment of the position of the screw 11.

[0035] Of course, the above description is not a limitation of this instruction manual, and this utility model is not limited to the examples mentioned above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of this utility model are also within the protection scope of this utility model.
