Description

Technical Field

[0001] This utility model belongs to the field of sanitary ware technology, and in particular relates to an anti-backflow ceramic toilet. Background Technology

[0002] An anti-backflow toilet is a type of toilet equipped with a backflow valve. When sewage flows back into the drain pipe, the backflow valve automatically closes, preventing sewage from entering the toilet and thus avoiding sewage backflow in the room.

[0003] When a conventional anti-backflow toilet encounters hard and large pieces of feces, such as feces from constipation, it can easily block the valve plate, preventing it from flushing properly. This can lead to a blockage at the valve plate, which is inconvenient to clean.

[0004] Therefore, we propose an anti-backflow ceramic toilet to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to solve the problem of inconvenient handling when the valve plate of a conventional anti-backflow toilet is blocked, and to propose an anti-backflow ceramic toilet.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An anti-backflow ceramic toilet includes an anti-backflow toilet body, a flushing pipe fixedly connected internally to the toilet body, a water valve fixedly connected externally to the flushing pipe, and a spring-loaded water tank fixedly connected to the lower part of the water valve. The spring-loaded water tank is connected to an external tap water pipe. First, a toilet lid is installed on the anti-backflow toilet body. The tap water pressure acts on the spring-loaded water tank to fill it with water. When the anti-backflow valve plate of the toilet body is blocked by feces, the toilet lid is closed, and the water valve is opened, allowing tap water to flow through the flushing pipe to form a high-pressure water flow. When the water flow is insufficient, the elasticity of the spring-loaded water tank acts on the stored water to ensure the impact duration of the high-pressure water flow. The high-pressure water flow breaks up the clumps of feces, allowing for regular flushing and facilitating the clearing of obstructions at the valve plate.

[0008] Preferably, the elastic water tank includes a tank shell, a movable plug, a bladder, a spring, and a fixing bolt. The upper end of the bladder is fixedly connected to the upper part of the tank shell, the lower end of the bladder is fixedly connected to the upper end of the movable plug, the lower end of the movable plug is fixedly connected to the upper end of the spring, and the fixing bolt is located at the lower end of the spring. The fixing bolt is fixedly installed on the lower part of the tank shell. When water is injected into the upper part of the tank shell, the water pressure acts on the bladder, causing it to stretch. This stretching acts on the movable plug, which in turn acts downwards on the spring. When discharging water, if the tap water flow rate is insufficient, the spring's elasticity acts on the movable plug, which in turn squeezes the bladder, forcing the water in the bladder into the water valve for replenishment, thus maintaining the continuity of high-pressure flushing.

[0009] Preferably, the elastic water tank further includes a washer ring, which is fixedly connected to the lower end of the spring and presses against the fixing bolt. The washer ring increases the stability of the spring acting on the fixing bolt.

[0010] Preferably, the housing includes a shell and a connecting ring, the connecting ring being fixedly connected inside the shell.

[0011] Preferably, the lower part of the housing has a hollowed-out insertion hole. This insertion hole increases the stability of the fixing bolt's connection to the housing.

[0012] Preferably, the housing further includes a connecting spout, which is fixedly connected to the upper part of the housing, and the internal space of the housing communicates with the internal space of the connecting spout. The connecting spout facilitates connection between the housing and a water pipe.

[0013] Preferably, the movable plug includes a push plate and a slip ring, with the push plate fixedly connected to the upper part of the slip ring. The slip ring guides the movable plug to slide within the housing, while the push plate acts on the bladder, reducing the local pressure on the bladder.

[0014] In summary, the technical effects and advantages of this utility model are as follows:

[0015] 1. First, install a toilet seat on the anti-backflow toilet body. Use the tap water pressure to fill the elastic water tank. When the anti-backflow valve plate of the anti-backflow toilet body is blocked by feces, close the toilet seat and then open the water valve to make the tap water form a high-pressure water flow through the flush pipe. When the water flow is insufficient, use the elasticity of the elastic water tank to act on the stored water to ensure the impact time of the high-pressure water flow. The high-pressure water flow acts on the feces to break up the clumps of feces. Then flush normally to make it easier to clean the obstruction at the valve plate.

[0016] 2. After water is injected into the upper part of the tank, the water pressure acts on the bladder, causing it to stretch. The bladder then acts on the movable plug, which in turn acts downward on the spring. When releasing water, if the tap water flow cannot keep up with the flow, the spring force acts on the movable plug, which squeezes the bladder and forces the water into the water valve to replenish it, thus maintaining the high-pressure flushing power.

[0024] Reference Figure 1 and 2The elastic water tank 2 includes a tank shell 3, a movable plug 4, a bladder 5, a spring 6, and a fixing bolt 8. The upper end of the tank shell 3 is fixedly connected to the water valve 10. The upper end of the bladder 5 is fixedly connected to the upper part of the tank shell 3. The lower end of the bladder 5 is fixedly connected to the upper end of the movable plug 4. The lower end of the movable plug 4 is fixedly connected to the upper end of the spring 6. The fixing bolt 8 is located at the lower end of the spring 6 and is fixedly installed on the lower part of the tank shell 3. When water is injected into the upper part of the tank shell 3, the water pressure acts on the bladder 5, causing it to stretch. The bladder 5 then acts on the movable plug 4, which in turn acts downwards on the spring 6. When water is released, if the tap water injection speed cannot keep up with the water supply, the elastic force of the spring 6 acts on the movable plug 4, which squeezes the bladder 5, forcing the water in the bladder 5 into the water valve 10 for replenishment.

[0025] Reference Figure 1 and 2 The elastic water tank 2 also includes a washer 7, which is fixedly connected to the lower end of the spring 6 and presses against the fixing bolt 8. The washer 7 increases the stability of the spring 6 acting on the fixing bolt 8.

[0026] Reference Figure 1 , 2 3. The housing 3 includes a housing 31 and a connecting ring 32. The upper end of the bladder 5 is fixedly connected to the connecting ring 32. The upper end of the housing 31 is fixedly connected to the water valve 10. The connecting ring 32 is fixedly connected inside the housing 31.

[0027] Reference Figure 2 and 3 The lower part of the housing 31 has a hollowed-out insertion hole 33. The fixing bolt 8 is fixedly inserted into the insertion hole 33.

The slip ring 42 is movably installed inside the housing 31, and the push plate 41 is fixedly connected to the lower end of the bladder 5 and the upper part of the slip ring 42. The slip ring 42 guides the movable plug 4 to slide along the inside of the housing 3, and the push plate 41 acts on the bladder 5 to reduce the local pressure on the bladder 5.

[0030] Working principle: First, a toilet lid is installed on the anti-backflow toilet body 1. The pressure of tap water acts on the elastic water tank 2 to fill the elastic water tank 2 with water. When the anti-backflow valve plate of the anti-backflow toilet body 1 is blocked by feces, the toilet lid is closed and the water valve 10 is opened, so that tap water forms a high-pressure water flow through the flush pipe 9. When the water flow is insufficient, the elasticity of the elastic water tank 2 acts on the stored water to ensure the impact time of the high-pressure water flow. The high-pressure water flow acts on the feces to break up the clumps of feces, and then the regular flush is performed to facilitate the cleaning of the obstruction at the valve plate.
