Description

Technical Field

[0001] The invention relates to the technical field of daily necessities, and in particular to a flush toilet capable of preventing water leakage. Background Art

[0002] According to the internal structure, flush toilets can be divided into ordinary ball valve flush toilets, automatic water-saving flush toilets, and pneumatic flush toilets. The working principle of the ball valve flush toilet is to use the buoyancy of the float and the principle of lever, and use the drain knob and water plug to control water discharge and water storage. When in use, rotate the drain knob, use the metal rope or nylon rope connected to the water plug to pull up the water plug, and the water plug will pull the outlet pipe port upward. The outlet pipe will put water into the toilet bowl and use the gravity of the water and the kinetic energy converted from potential energy to flush the excrement into the sewer pipe. When the water level drops to a certain level during flushing, the negative pressure generated by the gravity of the water will press the water plug back into the port of the outlet pipe, blocking the outlet and starting a new water storage stage. At the same time as the water level drops, the float and the lever will open the water replenishment mechanism and start to replenish water synchronously due to the gravity of the float. During the water replenishment stage, the buoyancy of the float and the lever are used to control the water replenishment of the water tank. When the float drops to the lowest position, the water plug is pressed into the outlet pipe by the negative pressure, and the water tank begins to store water; the water inlet pipe is connected to the tap water pipe to be responsible for the input of water source. When the water replenishment reaches a certain height, the buoyancy of the water will lift the float and the linkage lever will close the water supply mechanism to stop water replenishment.

[0003] When the ball valve kit of the existing ball valve type flush toilet is in use, the water inlet pipe and the water inlet valve are not crimped tightly. When the water filling reaches the required height, the water filling cannot be normally sealed to stop, resulting in frequent water leakage in the flush toilet. Summary of the invention

[0004] The technical problem to be solved by the present invention is: in order to overcome the deficiencies of the prior art, the present invention provides a flush toilet with a reasonable structural design, which can effectively seal the water filling port of the water inlet pipe after the water filling is completed to avoid water leakage.

[0005] The technical solution adopted by the present invention to solve its technical problems is: a flush toilet to prevent water leakage, including a water tank, a water inlet pipe, a downpipe and a float lever mechanism are arranged in the water tank, a water filling port is arranged on the top of the water inlet pipe, and the float lever mechanism includes a main support rod, a lever and a float, the main support rod is fixed in the water tank, the lever is rotatably connected to the top of the main support rod, the float is fixed to one end of the lever, and a sliding pin is arranged on the other end of the lever, a vertical track is fixed at the position of the sliding pin on the inner wall of the water tank, an upper slider is slidably connected in the vertical track, a waist-shaped hole is opened on the upper slider, the sliding pin is slidably inserted in the waist-shaped hole and drives the upper slider to slide up and down along the vertical track when the float floats up and down with the water level; a horizontal track is also arranged in parallel to the plane of the water filling port at the position corresponding to the water filling port in the water tank, and the horizontal track slides sequentially A left push cover and a right push cover are connected, a closing valve cover is fixed to the right end of the left push cover, and a closing valve cover is also fixed to the left end of the right push cover, the closing valve cover is arranged at the water replenishment port and seals the water replenishment port when closed, the left push cover and the right push cover are elastically connected by a spring, the left end face of the left push cover is an inclined surface, an internal hollow buoyancy guide column is arranged in the water tank below the inclined surface, a liquid inlet hole is arranged at the bottom of the buoyancy guide column, a lower sliding block is floatingly arranged in the buoyancy guide column, a hole is opened at the top of the buoyancy guide column for the buoyancy guide column to extend, the upper top face of the buoyancy guide column and the left end face of the left push cover are mutually matched inclined surfaces, and the left push cover approaches the right push cover direction along the horizontal track as the buoyancy guide column is raised; the right end face of the right push cover and the lower end face of the upper sliding block are also mutually matched inclined surfaces, and the right push cover approaches the left push cover direction along the horizontal track as the upper sliding block slides down.

[0006] In the above scheme, the sealing of the water filling port is achieved by closing the valve cover with a split design. By using the buoyancy of water, at the left push cover, the lower slider floats up under the action of buoyancy and pushes the left push cover to the right through the inclined surface. At the right push cover, the buoyancy of the floating ball drives the sliding pin to slide along the waist-shaped hole, so that the upper slider slides down and pushes the right push cover to the left through the inclined surface, completing the closing and sealing of the closed valve cover. After the water level drops, the pushing force disappears, and the spring force pushes the left push cover and the right push cover outward, the closed valve cover is separated, and the water filling port continues to be filled with water.

[0007] Furthermore, in order to improve the sealing performance of the closing valve cover when it is closed, the closing valve cover of the left push cover and the right push cover forms an upward lip structure at the position of the closing connection.

[0008] Preferably, the horizontal track is composed of two symmetrically arranged slide rails, the left push cover and the right push cover are respectively slidably connected between the two slide rails, and the closing valve cover does not interfere with the slide rails when moving with the left push cover and the right push cover. The symmetrically designed slide rails can effectively ensure that the left push cover and the right push cover can be effectively clamped during the movement without sliding, and ensure that the closing valve cover moves on the sealing plane of the water replenishment port, reducing the risk of water leakage. At the same time, the space formed between the opposing slide rails also provides a space for the upper slider to move downward to avoid interference.

[0009] The beneficial effect of the present invention is that the flush toilet that prevents water leakage provided by the present invention has a reasonable structural design. In the design of the ball valve kit, a float and a lever are used to effectively drive the water inlet cover of the split design. Under the limitation of the vertical track and the horizontal track, the opening and closing of the left push cover and the right push cover are effectively limited to ensure that when the float floats up, the water inlet cover is closed to effectively seal the water supply port, the sealing effect is good, and water leakage is not easy to occur.

DETAILED DESCRIPTION

[0014] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0015] like Figure 1 and Figure 2 The illustrated flush toilet for preventing water leakage is the best embodiment of the present invention, and comprises a water tank in which a water inlet pipe 5, a drain pipe and a float lever mechanism are arranged.

[0016] A water replenishment port 7 is provided at the top of the water inlet pipe 5, and the float lever mechanism includes a main support rod 15, a lever 16 and a float 17. The main support rod 15 is fixed in the water tank, and the lever 16 is rotatably connected to the top of the main support rod 15. The float 17 is fixed at one end of the lever 16, and a sliding pin 13 is provided at the other end of the lever 16. A vertical track 12 is fixed at the position of the sliding pin 13 on the inner wall of the water tank. An upper slider 11 is slidably connected in the vertical track 12, and a waist-shaped hole 10 is opened on the upper slider 11. The sliding pin 13 is slidably inserted in the waist-shaped hole 10 and drives the upper slider 11 to slide up and down along the vertical track 12 when the float 17 floats up and down with the water level.

[0017] A horizontal track 4 is provided in the water tank at the position corresponding to the water filling port 7 and parallel to the plane of the water filling port 7. The horizontal track 4 is composed of two symmetrically arranged slide rails, and the left push cover 6 and the right push cover 14 are slidably connected to the two slide rails in sequence. A closing valve cover 9 is fixed to the right end of the left push cover 6, and a closing valve cover 9 is also fixed to the left end of the right push cover 14. The closing valve cover 9 is arranged at the position of the water filling port 7 and seals the water filling port 7 when closed.

[0018] The left push cover 6 and the right push cover 14 are respectively slidably connected between the two slide rails, and the closing valve cover 9 does not interfere with the slide rails when moving with the left push cover 6 and the right push cover 14. The symmetrically designed slide rails can effectively ensure that the left push cover 6 and the right push cover 14 can be effectively clamped during the movement without sliding, ensuring that the closing valve cover 9 moves on the sealing plane of the water replenishment port 7, reducing the risk of water leakage. At the same time, the space formed between the opposing slide rails also provides a space for the upper slider 11 to move downward to avoid interference.

[0019] The sealing of the water supply port 7 is sealed by closing the closing valve cover 9 of the split design. In order to improve the sealing performance of the closing valve cover 9 when closing, the closing valve cover 9 of the left push cover 6 and the right push cover 14 forms an upward lip structure at the position of the closing connection. When the two closing valve covers 9 move with the left end cover and the right end cover, the lower end surface of the closing valve cover 9 is steadily pressed against the water supply port 7, and the water supply port 7 is effectively sealed after closing, and water is stopped from being added to the water tank.

[0020] The left push cover 6 is elastically connected to the right push cover 14 by a spring 8. The left end face of the left push cover 6 is an inclined surface. A hollow buoyancy guide column 2 is provided in the water tank corresponding to the lower part of the inclined surface. A liquid inlet hole 1 is provided at the bottom of the buoyancy guide column 2. The design of the liquid inlet hole 1 makes the water level in the buoyancy guide column 2 consistent with the water level in the water tank. At the same time, in order to ensure the synchronization of the water levels, the number of the liquid inlet holes 1 can be set to multiple. A lower slider 3 is provided in the buoyancy guide column 2. A hole is provided at the top of the buoyancy guide column 2 for the buoyancy guide column 2 to extend. The length of the lower slider 3 in the vertical direction needs to be designed according to the floating distance and the height of the buoyancy guide column 2 to ensure that the lower end of the lower slider 3 is still limitedly connected in the buoyancy guide column 2 when the lower slider 3 floats to the highest height, so as to avoid floating and falling off from the top of the buoyancy guide column 2. The upper top surface of the buoyancy guide column 2 and the left end face of the left push cover 6 are mutually matched inclined surfaces. The left push cover 6 approaches the right push cover 14 along the horizontal track 4 as the buoyancy guide column 2 is lifted. The right side end surface of the right push cover 14 and the lower end surface of the upper slider 11 are also mutually matched inclined surfaces. As the upper slider 11 slides downward, the right push cover 14 moves closer to the left push cover 6 along the horizontal track 4.

[0021] Water replenishment principle:

[0022] The buoyancy of water, the principle of the lever 16 and the coordination of the inclined plane are utilized to realize the opening and closing of the closing valve cover 9 on the sealing plane of the water replenishment port 7 .

[0023] Hydration process:

[0024] After flushing, the water level in the water tank drops. On the left push cover 6 side, the lower slider 3 drops with the water level and no longer squeezes the left push cover 6. The left push cover 6 moves to the left under the elastic force of the spring 8. The left push cover 6 drives the corresponding closing valve cover 9 to the left, and the left side of the water supply port 7 opens. On the right push cover 14 side, the float 17 drops, and one end of the sliding pin 13 of the lever 16 tilts upward to drive the upper slider 11 to move upward along the vertical track 12. The upper slider 11 no longer squeezes the right push cover 14. The right push cover 14 moves to the right under the elastic force of the spring 8. The right push cover 14 drives the corresponding closing valve cover 9 to the right, and the right side of the water supply port 7 opens. At this time, the water supply port 7 is opened to replenish the water tank. When replenishing water, the water level in the water tank gradually rises.

[0025] When the water level in the water tank rises, the lower slider 3 and the float 17 rise synchronously with the water level. At the left push cover 6, the lower slider 3 floats up under the action of buoyancy until it pushes the left push cover 6 to the right through the inclined surface, and the left push cover 6 drives the closing valve cover 9 to move to the right. At the right push cover 14, the buoyancy of the float 17 drives the sliding pin 13 to slide along the waist-shaped hole 10, and the upper slider 11 slides down and pushes the right push cover 14 to the left through the inclined surface, and the right push cover 14 drives the closing valve cover 9 to move to the left. At this time, the left push cover 6 and the right push cover 14 overcome the elastic force of the spring 8 under the action of buoyancy, realize relative movement, and finally complete the closing and sealing of the closing valve cover 9.

[0026] After flushing again, the water level drops, the squeezing thrust disappears, the elastic force of the spring 8 pushes the left push cover 6 and the right push cover outward, the closing valve cover 9 is separated, and the water filling port 7 continues to fill water, and so on.

[0027] The anti-leakage flush toilet designed in this way has a reasonable structural design. In the design of the ball valve kit, the float 17 and the lever 16 are used to effectively drive the water inlet cover of the split design. Under the limit of the vertical track 12 and the horizontal track 4, the opening and closing of the left push cover and the right push cover are effectively limited to ensure that when the float 17 floats up, the water inlet cover is closed to effectively seal the water supply port 7, the sealing effect is good, and it is not easy to leak.

[0028] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
