[0028] Please refer to Figures 1 - 4 , an embodiment provided by the present utility model:
[0029] A sunken anti-siphon structure ceramic toilet, which includes:
[0030] A sunken ceramic toilet body 1, an flushing tank 4 is arranged above the inside of the sunken ceramic toilet body 1, a flushing pipe 2 is arranged at one end of the flushing tank 4 above the inside of the sunken ceramic toilet body 1, a siphon sewage discharge pipe 5 is arranged inside the sunken ceramic toilet body 1, a spray pipe 3 is arranged inside the sunken ceramic toilet body 1, a mounting plate 13 is fixedly installed above the spray pipe 3 inside the sunken ceramic toilet body 1, and a valve stem 14 is rotatably installed inside the spray pipe 3;
[0031] A valve plate 15 is fixedly installed on the outer wall of the valve stem 14, and the valve plate 15 is located inside the spray pipe 3. The top end of the valve stem 14 penetrates through the spray pipe 3 and extends above the spray pipe 3. A first motor 12 is fixedly installed on the top of the mounting plate 13, and the driving end of the first motor 12 penetrates through the mounting plate 13 and is fixedly connected to the top end of the valve stem 14.
[0032] On the front of the sunken ceramic toilet body 1, a track 6 is fixedly installed. Inside the track 6, a threaded rod 18 is rotatably installed. A regulating block 7 is sleeved on the outer wall of the threaded rod 18, and the regulating block 7 is slidably connected to the track 6. A connecting block 8 is fixedly installed on the front of the regulating block 7. A connecting plate 9 is fixedly installed on the front of the connecting block 8. A support plate 11 is fixedly installed below the front of the connecting plate 9. Above the back of the track 6, a driving mechanism is arranged inside the sunken ceramic toilet body 1.
[0033] In one embodiment, the driving mechanism includes a second motor 20, and the second motor 20 is fixedly installed above the back of the track 6 and inside the sunken ceramic toilet body 1. The driving end of the second motor 20 penetrates through the track 6 and extends into the inside of the track 6. A worm 17 is fixedly installed at the driving end of the second motor 20. A worm gear 16 is fixedly installed on the outer wall of the top end of the threaded rod 18, and the worm gear 16 meshes with the worm 17.
[0034] In one preferred embodiment, a limiting block 19 is fixedly installed above the inside of the track 6 to limit the position of the regulating block 7 and prevent the regulating block 7 from colliding with the worm 17 and the worm gear 16.
[0035] In one embodiment, diagonal braces 10 are fixedly installed between the two sides of the front of the connecting plate 9 and the two sides of the top of the support plate 11, improving the connection strength between the connecting plate 9 and the support plate 11, enhancing its load-bearing capacity, and enabling more stable support for the user's feet.
[0036] In one preferred embodiment, a threaded hole adapted to the threaded rod 18 is opened at the top of the regulating block 7, and the regulating block 7 is threadedly connected to the threaded rod 18 through the threaded hole opened at its top.
[0037] In one embodiment, the front side of the support plate 11 is inclined, and an anti-slip pad is bonded to the top of the support plate 11. Through the setting of the anti-slip pad, the friction between the support plate 11 and the user's feet is increased, making the support for the user's feet more stable.
[0038] The working principle of the present utility model is as follows: All electrical components appearing in this application are externally connected to a power supply and a control switch during use. When the user uses this toilet, after using the toilet, press the flushing switch, and the water in the internal water tank of the sunken ceramic toilet body 1 will be sprayed out through the pump body from the flushing pipe 2 and the spray pipe 3. The water sprayed out through the flushing pipe 2 will directly form a tornado-like swirling flush under the action of the flushing trough 4, and flush the feces inside the sunken ceramic toilet body 1 into the internal of the siphon sewage pipe 5 together. At the same time, the first motor 12 will receive a signal and start working. The driving end of the first motor 12 drives the valve rod 14 to rotate, and the rotation of the valve rod 14 drives the valve plate 15 to rotate. The valve plate 15 will lose the sealing effect on the spray pipe 3, so that the water sprayed out through the spray pipe 3 will directly rush into the internal of the siphon sewage pipe 5, causing siphon to be generated instantly, ensuring that the feces inside the sunken ceramic toilet body 1 will be thoroughly discharged into the sewage pipe through the siphon sewage pipe 5. This is the case when the toilet is supplied with normal water, and each structure can cooperate and operate stably. When the sunken ceramic toilet body 1 is not in the flushing state, the valve plate 15 always seals the spray pipe 3. Therefore, when the water supply of the toilet is insufficient or the water supply is cut off, the negative pressure formed inside the toilet cannot overcome the seal of the valve plate 15, and the dirty water inside the toilet will not flow back into the water supply pipe, eliminating the potential health hazards that may occur during water supply shortages. This makes the design of the valve plate 15 of the sunken ceramic toilet effectively prevent the pollution of the water supply system by sewage, improving the quality of residents' lives and the level of hygiene and safety, whether in daily use or in the case of abnormal water supply.
[0039] During the process of the user using the toilet, from a physiological perspective, the larger the anorectal angle, the straighter the rectum, and the smoother the defecation. Therefore, many people will step on a small stool to raise their feet eight to ten centimeters during the process of using the toilet to help with defecation. During the process of using this sunken ceramic toilet body 1, the user directly places both feet on the top of the support plate 11, and then controls the second motor 20 to start working. The driving end of the second motor 20 drives the worm 17 to rotate. Through the meshing of the worm 17 and the worm gear 16, the worm gear 16 drives the threaded rod 18 to rotate. Through the threaded transmission between the threaded rod 18 and the adjusting block 7, and the sliding relationship between the adjusting block 7 and the track 6, the adjusting block 7 moves vertically stably. The movement of the adjusting block 7 drives the connecting plate 9 to move through the connecting block 8, and the connecting plate 9 drives the support plate 11 to move. The upward movement of the support plate 11 can directly raise the user's feet upward. The specific height of the raise can be adjusted by the user himself, avoiding the need for the user to carry a stool to achieve smooth defecation, making it more convenient for the user to use. When the support plate 11 is not in use, its height can be directly lowered to contact the ground, avoiding collision with the human body, and ensuring safety during use through its flexible adjustability.
[0040] It should be noted that when the sunken anti-siphon structure ceramic toilet of the present utility model is in use, the connection mode of the flushing pipe 2 and the spraying pipe 3 is the prior art and can be realized by the prior art. The present utility model only aims to solve the problem that in the existing sunken anti-siphon structure ceramic toilet, when there is a short-term water outage or abnormal reduction of water pressure in the urban water supply system, since the toilet tank fails to be filled with water in time, there may still be a certain amount of dirty water in the toilet. In this case, through the pipeline of the water inlet device, it is siphoned into the water supply pipeline, polluting the water source in the water supply pipeline and bringing huge hygienic and safety hazards to people's lives.
[0041] The above shows and describes the basic principle, main features and advantages of the present utility model.
