Description

Technical Field

[0001] The utility model relates to the technical field of daily necessities, and specifically relates to a self-cleaning device for a toilet. Background Technique

[0002] As an important means for people to handle excrement and other dirt in urban life, the toilet has become an essential household appliance in people's daily life. Currently, toilets on the market are classified into four types according to the sewage discharge method: flush-down type, siphon flush-down type, siphon jet type, and siphon vortex type. However, no matter which type of toilet is used for a long time, a large amount of dirt will adhere to its inner side. If not cleaned for a long time, it will not only block the toilet but also have a great impact on the indoor environment. After using the toilet, adding a certain amount of cleaning liquid to the water tank and then flushing can effectively eliminate odors. Regular use of the cleaning liquid can remove stains to prevent the generation of odors and eliminate the yellow stains on the toilet wall.

[0003] Currently, the common cleaning method for water toilets is to add the cleaning liquid into the water tank. The components contained in the cleaning liquid will be slowly released in the water tank, and each time the toilet is flushed, a fragrant water flow with a certain amount of cleaning components will flow out. While removing dirt, it can form a protective film on the toilet bowl wall to prevent scale formation. However, this method has some defects. If the toilet is used frequently, too little cleaning liquid will be dissolved and the concentration will be relatively low, unable to achieve a good cleaning effect; if the toilet is used only once in a long time, too much cleaning liquid will be dissolved, resulting in waste of the cleaning liquid; and even it may corrode the components in the water tank due to too high a concentration of the cleaning liquid, causing damage to the components. Therefore, we propose a device that can quantitatively add the cleaning liquid to the water tank and quickly dissolve the cleaning liquid, that is, a self-cleaning device for a toilet. Content of the Utility Model

[0004] The purpose of the utility model is to provide a self-cleaning device for a toilet to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides a self-cleaning device for a toilet, including a water tank. A liquid extraction tank is fixedly connected to the right inner wall of the water tank. A piston is slidably connected to the bottom of the liquid extraction tank. The bottom end of the piston is fixedly connected to a support rod. The bottom end of the support rod is fixedly connected to a floating ball. A bent pipe is fixedly connected to the top end of the liquid extraction tank. The other end of the bent pipe is fixedly connected to the bottom end of a liquid storage box. A feed port is opened at the top end of the liquid storage box. A plurality of support plates are fixedly connected to the bottom end of the liquid storage box. The left end of the support plate is fixedly connected to the water tank. A square pipe is fixedly connected to the left end of the liquid extraction tank.

[0006] As a further improvement of the technical solution, an inlet and an outlet are respectively provided at the top end and the left end of the liquid extraction box. A rotating shaft is rotatably connected to the left side of the bottom end of the inlet and the top left side of the outlet, and a baffle is fixedly connected to the outer side of the rotating shaft.

[0007] As a further improvement of the technical solution, grooves are provided at the right side of the bottom end of the inlet and the bottom left side of the outlet, and the grooves correspond to the baffles.

[0008] As a further improvement of the technical solution, a rubber ring is fixedly connected to the outer surface of the piston, and the rubber ring is in close fit with the inner wall of the liquid extraction box.

[0009] As a further improvement of the technical solution, a weight increasing block is fixedly connected between the support rod and the floating ball, and the gravity of the weight increasing block is less than the buoyancy of the floating ball.

[0010] As a further improvement of the technical solution, the square pipe has an "L" - shaped structure. A horizontal pipe is fixedly connected to the bottom of the square pipe, and a plurality of round holes are provided at the bottom end of the horizontal pipe, and the round holes are evenly distributed on the bottom surface of the horizontal pipe.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] When the self - cleaning device for the toilet flushes the toilet, the water in the water tank gradually decreases, the floating ball moves downward following the water surface, drives the piston to move downward, and pumps the cleaning liquid in the liquid storage box to the liquid extraction box. When water is added to the water tank, the water surface rises, the floating ball moves upward following the water surface, pushes the piston to compress the cleaning liquid in the liquid extraction box. The cleaning liquid contacts the baffle on the upper side of the liquid extraction box and pushes it to be clamped with the groove, thereby blocking the inlet. The cleaning liquid pushes the baffle on the left side of the liquid extraction box, enters the square pipe, and enters the water tank from the round holes at the bottom end of the horizontal pipe, and is evenly mixed with the water in the water tank, achieving the effect of quantitatively adding the cleaning liquid to the water tank and quickly dissolving the cleaning liquid.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0020] As an important means for people to handle excrement and other dirt in urban life, the toilet has become an essential household item in people's daily life. Currently, toilets on the market are classified into four types according to the sewage discharge method: flush-down type, siphon flush-down type, siphon jet type, and siphon vortex type. However, no matter which type of toilet is used for a long time, a large amount of dirt will adhere to its inner side. If not cleaned for a long time, it will not only block the toilet but also have a great impact on the indoor environment. After using the toilet, adding a certain amount of cleaning liquid to the water tank and then flushing can effectively eliminate odors. Regular use of the cleaning liquid can remove stains to prevent the generation of odors and eliminate the yellow stains on the toilet wall. Please refer to Figures 1 - 4 As shown, the present invention provides a self-cleaning device for a toilet, including a water tank 1. The right inner wall of the water tank 1 is fixedly connected with a liquid extraction box 2. The bottom of the liquid extraction box 2 is slidably connected with a piston 4. The bottom end of the piston 4 is fixedly connected with a support rod 42. The bottom end of the support rod 42 is fixedly connected with a floating ball 44. The top end of the liquid extraction box 2 is fixedly connected with an elbow tube 52. The other end of the elbow tube 52 is fixedly connected with the bottom end of a liquid storage box 5. The top end of the liquid storage box 5 is provided with a feed inlet 51. The bottom end of the liquid storage box 5 is fixedly connected with a plurality of support plates 11. The left end of the support plate 11 is fixedly connected with the water tank 1. The left end of the liquid extraction box 2 is fixedly connected with a square tube 3.

[0021] The improvement of the present invention lies in:

[0022] Since the common cleaning method of a water toilet is to add a cleaning liquid into the water tank 1, the components contained in the cleaning liquid will be slowly released in the water tank 1. Each time when flushing the toilet, a scented water flow with certain cleaning components will flow out. While removing dirt, it can form a protective film on the inner wall of the toilet bowl to prevent scaling. However, this method has some defects. If the toilet is used frequently, the dissolved cleaning liquid will be too little and the concentration will be too low to achieve a good cleaning effect. If the toilet is used only once in a long time, the dissolved cleaning liquid will be too much, resulting in waste of the cleaning liquid. Even worse, due to the too high concentration of the cleaning liquid, the components in the water tank 1 may be corroded, causing damage to the components. When the toilet is flushing, the water level in the water tank 1 drops, and the float ball 44 moves downward following the water level, thereby driving the piston 4 to move downward. At the same time, the cleaning liquid in the liquid storage box 5 is pumped into the liquid pumping tank 2. When adding water to the water tank 1, the water level rises, and the float ball 44 moves upward following the water level, pushing the piston 4 to compress the cleaning liquid. The cleaning liquid pushes the baffle 24 on the left side of the liquid pumping tank 2 and enters the square tube 3, and then enters the water tank 1 from the round hole 32 at the bottom end of the horizontal tube 31, and is evenly mixed with the water in the water tank 1. According to the amount of water used in the water tank 1, the corresponding cleaning liquid is added to the water tank 1, and when adding water, the cleaning liquid is evenly mixed in the water tank 1.

[0023] Considering that the outlet 22 needs to be blocked during liquid pumping and the inlet 21 needs to be blocked when pressing the cleaning liquid, therefore, an inlet 21 and an outlet 22 are respectively opened at the top end and the left end of the liquid pumping tank 2. A rotating shaft 25 is rotatably connected to the left side of the bottom end of the inlet 21 and the left side of the top end of the outlet 22. A baffle 24 is fixedly connected to the outside of the rotating shaft 25. By rotating the baffle 24 around the rotating shaft 25, the opening and closing of the inlet 21 and the outlet 22 are realized. During liquid pumping, the baffle 24 at the inlet 21 is in an open state under the action of gravity. When compressing the cleaning liquid, the cleaning liquid contacts the baffle 24 on the upper side of the liquid pumping tank 2 and pushes it to be clamped with the groove 23, thereby blocking the inlet 21. The cleaning liquid can only push the baffle 24 from the outlet 22 into the square tube 3.

[0024] In order to better limit the baffle 24 and improve the blocking effect of the baffle 24, therefore, grooves 23 are respectively opened at the right side of the bottom end of the inlet 21 and the left side of the bottom end of the outlet 22. The grooves 23 correspond to the baffle 24, ensuring that the baffle 24 at the bottom end of the inlet 21 cannot move upward and the baffle 24 on the left side of the outlet 22 cannot move to the right, thereby limiting the baffle 24 and making the blocking effect of the baffle 24 more obvious.

[0025] Considering that the liquid pumping tank 2 needs to have good sealing performance, therefore, a rubber ring 41 is fixedly connected to the outer surface of the piston 4. The rubber ring 41 is closely attached to the inner wall of the liquid pumping tank 2. The rubber ring 41 has good sealing performance, which can ensure that when the piston 4 moves downward, the cleaning liquid in the liquid storage box 5 is pumped into the liquid pumping tank 2.

[0026] In order to enable the floating ball 44 to move along with the water surface and drive the piston 4 to pump and compress the cleaning liquid, a weight block 43 is fixedly connected between the support rod 42 and the floating ball 44. The gravity of the weight block 43 is less than the buoyancy of the floating ball 44. The weight block 43 provides sufficient gravity for the support rod 42 to ensure that the piston 4 can be driven to move downward and the floating ball 44 can push the piston 4 to move upward.

[0027] In order to improve the mixing efficiency of the cleaning liquid and the water in the water tank 1, the square pipe 3 is in an "L" shape. A horizontal pipe 31 is fixedly connected to the bottom of the square pipe 3. A number of round holes 32 are opened at the bottom end of the horizontal pipe 31. The round holes 32 are evenly distributed on the bottom surface of the horizontal pipe 31. The cleaning liquid reaches the horizontal pipe 31 through the square pipe 3, ensuring that the cleaning liquid can enter the water tank 1 from multiple directions and improving the dissolution rate of the cleaning liquid.

[0028] In summary, the working principle of this solution is as follows:

[0029] When flushing the toilet, the water in the water tank 1 gradually decreases. The floating ball 44 moves downward along with the water surface, driving the piston 4 to move downward and pumping the cleaning liquid in the liquid storage box 5 to the liquid pumping tank 2. When adding water to the water tank 1, the water surface rises. The floating ball 44 moves upward along with the water surface, pushing the piston 4 to compress the cleaning liquid in the liquid pumping tank 2. The cleaning liquid contacts the baffle 24 on the upper side of the liquid pumping tank 2 and pushes it to be clamped with the groove 23, thereby blocking the inlet 21. The cleaning liquid pushes the baffle 24 on the left side of the liquid pumping tank 2, enters the square pipe 3, and enters the water tank 1 from the round holes 32 at the bottom end of the horizontal pipe 31, being evenly mixed with the water in the water tank 1, achieving the effect of quantitatively adding the cleaning liquid to the water tank 1 and quickly dissolving the cleaning liquid.
