Description

Technical Field

[0001] The utility model relates to a toilet companion, and particularly to a toilet companion with a filtering structure. Background Art

[0002] At present, a Chinese patent with the publication number CN218562501U discloses a filtering type toilet companion, which includes a main body, a fitting and a spray gun placement member. A water inlet pipe is arranged in the middle of the bottom surface of the main body. A spray gun connection end is arranged at the left front part of the main body, a toilet connection end is arranged at the right front part of the main body, and two switch valve cores are arranged at the rear end of the main body. The two switch valve cores are respectively communicated with the spray gun connection end and the toilet connection end. A cross filtering channel is arranged in the middle of the main body. The bottom of the cross filtering channel is communicated with the water inlet pipe, and the left and right ends of the cross filtering channel are respectively communicated with the spray gun connection end and the toilet connection end. The fitting is arranged in the middle of the upper end surface of the main body. A threaded block screwed into the top of the cross filtering channel is arranged on the bottom surface of the fitting. A filtering member with a downward-facing notch is threadedly connected to the lower end of the threaded block. A filtering grid is arranged on the outer wall of the middle part of the filtering member. The spray gun placement member is arranged on the upper part of the fitting, and a placement groove is arranged on the spray gun placement member.

[0003] After the above toilet companion is used for a period of time, the fitting can be rotated to screw the threaded block out of the top of the cross filtering channel, so that the filtering member is separated from the main body, and then the filtering member on the threaded block can be screwed out for replacement. However, when replacing the filtering member in the above toilet companion, water will spray out from the top of the cross filtering channel, resulting in waste of water resources. Summary of the Invention

[0004] In view of this, the purpose of the utility model is to provide a toilet companion with a filtering structure, which has the advantages that when replacing the filter screen, water is not easy to spray out and water resource waste is not easy to cause.

[0005] In order to solve the above technical problems, the technical solution of the utility model is: a toilet companion with a filtering structure, comprising a body, a toilet connecting pipe is provided on the right side of the lower end of the body, a control valve 1 is provided on the right side of the upper end of the body, the control valve 1 is used to control the opening and closing of the toilet connecting pipe, a spray gun connecting pipe is provided on the left side of the lower end of the body, a control valve 2 is provided on the left side of the upper end of the body, the control valve 2 is used to control the opening and closing of the spray gun connecting pipe, a water inlet pipe is provided at the rear end of the body, a threaded hole is provided at the front end of the body, a plug is threadedly connected to the threaded hole, a spray gun fixing seat is provided at the front end of the plug, an annular filter is provided on the inner side of the body, the The two ends of the filter screen respectively resist the plug and the water inlet pipe, and also include a water stop rod. The rear end width of the water stop rod is larger than the front end width of the water stop rod. The rear end of the water stop rod is slidably arranged in the water inlet pipe, and the front end of the water stop rod extends into the main body and resists the plug. A sealing ring is embedded in the rear side of the front end of the water stop rod. When the plug is threadedly connected to the main body, the rear end of the water stop rod is separated from the rear end of the main body, and the water inlet pipe is connected to the main body. When the plug is separated from the main body, the water stop rod slides toward the main body under the action of water pressure, and the rear end of the water stop rod presses the sealing ring and the rear end of the main body, and the water inlet pipe is separated from the main body.

[0006] According to the above technical solution, during use, the water inlet pipe is connected to the tap water pipe, and water enters the main body through the water inlet pipe. When control valve 1 is open, water in the main body flows out through the toilet connecting pipe and enters the toilet water tank. When control valve 2 is open, water in the main body flows out through the spray gun connecting pipe and enters the spray gun. At this point, the spray gun can be removed from the spray gun holder to clean the toilet. As water flows through the main body, the filter can be used to filter impurities in the water. When a large amount of impurities accumulate in the filter, the plug is rotated in the opposite direction to separate it from the main body. This allows the filter to be removed and cleaned or replaced without turning off the water. Simultaneously, the water stop rod slides toward the main body under the action of water pressure. The rear end of the water stop rod presses the seal against the rear end of the main body, isolating the water inlet pipe from the main body. This prevents water from spraying out of the threaded hole when cleaning or replacing the filter, thereby reducing water waste to a certain extent.

[0007] Preferably, a sealing hole is opened at the rear end of the threaded hole, and a sealing tube is provided at the rear end of the plug. The sealing tube extends into the sealing hole, and an O-ring is embedded on the outside of the sealing tube. The O-ring is tightly pressed against the inner wall of the sealing hole. When the rear end of the water stop rod presses the sealing ring against the main body, the O-ring is still tightly pressed against the inner wall of the sealing hole.

[0008] Through the above technical solution, during the process of screwing out the plug, the O-ring is always in tight contact with the inner wall of the sealing hole, so as to prevent water from flowing into through the water inlet pipe and spraying out through the threaded hole when the sealing ring is not in tight contact with the rear end of the body, further reducing the waste of water resources.

[0009] Preferably, the water stop rod includes a plugging section and a water inlet section arranged at the front end of the plugging section. A water outlet groove is formed at the rear end of the plugging section, a water outlet hole is formed at the side wall of the plugging section, the water outlet hole is communicated with the water outlet groove, a water passing groove is formed at the front end of the water inlet section, a water passing hole is formed at the side wall of the water inlet section, and the water passing hole is communicated with the water passing groove.

[0010] Through the above technical solution, when the plug is connected to the body, the water in the water inlet pipe can sequentially flow through the water outlet groove, the water outlet hole, the water passing hole and the water passing groove, and then enter the filter screen.

[0011] Preferably, a retaining ring is arranged at the rear end edge of the plugging section, and the outer ring of the retaining ring abuts against the inner side of the water inlet pipe.

[0012] Through the above technical solution, the retaining ring can limit the sliding of the water stop rod, so that the water stop rod is not prone to deflection during the sliding process.

[0013] Preferably, a water passing ring groove is formed in the inner side of the front end of the water inlet pipe, and the water passing ring groove is communicated with the water outlet hole.

[0014] Through the above technical solution, a water passing ring groove is formed in the inner side of the front end of the water inlet pipe to increase the gap through which water can flow, so as to achieve the purpose of increasing the flow rate.

[0015] Preferably, the rear end of the water inlet pipe is reduced in diameter to form a limiting end, and the limiting end is used to abut against the rear end of the retaining ring.

[0016] Through the above technical solution, the limiting end can be used to block the water stop rod, so that the water stop rod is not prone to sliding out of the water inlet pipe.

[0017] Preferably, a limiting snap ring is clamped in the inner side of the rear end of the water inlet pipe, and the limiting snap ring is used to abut against the rear end of the retaining ring.

[0018] Through the above technical solution, the limiting snap ring can be used to block the water stop rod, so that the water stop rod is not prone to sliding out of the water inlet pipe.

[0019] Preferably, a spline slot is formed at the front end of the plug, and the spray gun fixing seat includes a spline insert block inserted and fixed inside the spline slot and a fixed snap ring fixedly arranged on the outer side of the front end of the spline insert block.

[0020] Through the above technical solution, the spray gun fixing seat is inserted and fixed with the plug, which has the advantage of being relatively convenient for disassembly and assembly. The spline slot and the spline insert cooperate with each other to restrict the circumferential rotation of the fixing snap ring, making the placement of the spray gun more stable.

[0021] Preferably, a countersunk hole is provided at the front end of the spline insert, a locking screw is arranged in the countersunk hole, the head of the locking screw abuts against the inner side of the rear end of the countersunk hole, and the threaded section of the locking screw is threadedly connected to the plug.

[0022] Through the above technical solution, the locking screw presses and fixes the spline insert and the plug, which can improve the connection stability between the spray gun fixing seat and the plug.

[0023] Preferably, a movable snap ring is inserted inside the fixing snap ring, an outward turning edge is provided at the upper end of the movable snap ring, the outward turning edge abuts against the upper end of the fixing snap ring, a positioning protrusion is provided on the outer side of the movable snap ring, and the positioning protrusion is located in the countersunk hole.

[0024] Through the above technical solution, the movable snap ring blocks the locking screw, which can effectively avoid the situation of the locking screw being stuck. The outward turning edge abuts against the upper end of the fixing snap ring, which can be used to limit the downward movement of the movable snap ring. The positioning protrusion is located in the countersunk hole, which can be used to limit the upward movement of the movable snap ring, thereby avoiding the situation of the separation of the movable snap ring and the fixing snap ring.
