A water inlet valve is installed inside a water tank. The water inlet valve is connected to a water source, so that the water source flows into the space inside the toilet water tank along the water inlet valve. When the water level inside the water tank reaches a set drainage volume, the water inlet valve automatically stops supplying water to the inside of the water tank. By providing a drain valve inside the water tank, the water source inside the water tank is discharged by pressing a flush button on the top of the drain valve for flushing the toilet.

DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0032] like Figures 1 to 5 As shown, a water-saving toilet according to the present invention comprises a barrel body 1 and a water tank 2, wherein the water tank 2 comprises a water inlet valve 21 and a drain valve 22, and further comprises: a suspension device, wherein the suspension device is symmetrically placed inside the water tank 2, and the suspension device rises and falls with the change of the water level inside the water tank 2;

[0033] Auxiliary device, the auxiliary device is symmetrically designed on both sides of the drain valve 22, and the auxiliary device is used to assist the flush button to reset in time;

[0034] Connecting piece; the connecting piece is used to connect the suspension device and the auxiliary device, and the length of the connecting piece is less than the distance that the suspension device slides up and down;

[0035] During operation, the flush button of a common toilet in life often fails to reset after being used for a period of time. After pressing the flush button, the person leaves without noticing whether the flush button has been reset in time. When the flush button fails to reset in time, the water inside the toilet tank 2 will continue to flush the toilet, thereby causing a large amount of water waste. By installing an inlet valve 21 inside the water tank 2, the inlet valve 21 is connected to a water source, so that the water source flows into the space inside the toilet tank 2 along the inlet valve 21. When the water level inside the water tank 2 reaches the set water storage volume, the inlet valve 21 automatically stops supplying water to the inside of the water tank 2. By providing a drain valve 22 inside the water tank 2, pressing the flush button on the top of the drain valve 22 allows the water to flow out of the water tank 2. The water source inside the water tank 2 is discharged to flush the toilet. Since a suspension device is installed inside the water tank 2, the height of the suspension device in the water tank 2 changes with the water level inside the water tank 2. An auxiliary device is fixedly installed on both sides of the drain valve 22, and the auxiliary device is connected to the suspension device through a connecting piece. When the flush button is pressed, the water level inside the water tank 2 drops, and the suspension device inside the water tank 2 moves downward synchronously with the water level. When the suspension device moves downward to the bottom of the water tank 2, the end of the auxiliary device close to the drain valve 22 is driven to tilt upward by the connecting piece, and the auxiliary flush button is reset in time, which can effectively reduce the probability that the flush button cannot be reset in time, and simultaneously reduce water waste, thereby achieving a water-saving effect for the toilet.

[0036] As an embodiment of the present invention, the suspension device is a float chamber 23 of rectangular parallelepiped structure, and a water inlet groove is provided on the surface of the float chamber 23 near the drain valve 22;

[0037] During operation, since the suspension device is a float chamber 23 designed with a rectangular structure, the float chamber 23 can move with the changes in the water level inside the water tank 2. By opening a water inlet groove in the middle of the surface of the float chamber 23 on one side close to the drain valve 22, when the water injected into the water tank 2 reaches the set value, the water inside the water tank 2 will enter the space inside the float chamber 23 along the water inlet groove, thereby increasing the gravity of the float chamber 23. When the flush button is pressed to flush the toilet, as the gravity of the float chamber 23 increases, the downward pulling force of the auxiliary device away from the drain valve 22 can be effectively increased, so that when the float chamber 23 moves to the bottom of the water tank 2, the auxiliary device is quickly driven by the connecting piece to assist in resetting the flush button in time, closing the drain valve 22, and reducing the waste of water.

[0038] As an embodiment of the present invention, the end of the float chamber 23 close to the side wall of the water tank 2 is slidably connected to a sliding rod 231, and the end of the sliding rod 231 away from the float chamber 23 is fixed to the side wall of the water tank 2;

[0039] During operation, the float chamber 23 slides up and down along the length direction of the sliding rod 231 by fixing and connecting the evenly arranged sliding rods 231 on the inner wall of the water tank 2. The coordinated design of the sliding rod 231 and the float chamber 23 can effectively prevent the float chamber 23 from floating freely in the water tank 2, thereby limiting the sliding direction of the float chamber 23, and enabling the float chamber 23 to cooperate with the connecting parts and the auxiliary unit in time to assist in resetting the flush button in time, thereby further reducing the waste of water resources inside the water tank 2.

[0040] As an embodiment of the present invention, the auxiliary device includes: a support column 24, the support column 24 is fixedly connected to the bottom of the drain valve 22;

[0041] A support frame 241, wherein the upper surface of each support column 24 is fixedly connected with a support frame 241 of symmetrical design;

[0042] A movable rod 242 is hinged between the two symmetrically designed support frames 241, and a fixed column 243 is hinged between the movable rod 242 and the flush button on the top of the drain valve 22;

[0043] During operation, since the two sides of the drain valve 22 are fixedly connected to the evenly arranged support columns 24, the top surface of each support column 24 is fixedly connected to the evenly arranged support frame 241, and a movable rod 242 is hinged between two adjacent support frames 241. The movable rod 242 extends to one end above the drain valve 22 and is fixedly connected to a fixed column 243. The movable rod 242 is fixedly connected to the float chamber 23 at one end away from the drain valve 22 through a connecting piece. When the moving distance of the float chamber 23 is greater than the length of the connecting piece, it drives the movable rod 242 to move downward away from the end of the drain valve 22, forcing the movable rod 242 to move upward close to the end of the drain valve 22, driving the fixed column 243 to move upward synchronously, assisting the flush button to be reset in time, and effectively avoiding the situation where the flush button is not reset in time.

[0044] As an embodiment of the present invention, the movable rod 242 is designed in a Y-shaped structure at one end close to the drain valve 22, and the movable rod 242 above the drain valve 22 is hinged with a fixing column 243;

[0045] During operation, the movable rod 242 is designed with a Y-shaped structure at one end near the drain valve 22, and the movable rod 242 is fixedly connected to the one end near the drain valve 22 with evenly arranged fixed columns 243. When the movable rod 242 is subjected to force and tilts upward at one end near the drain valve 22, the movable rod 242 drives the fixed columns 243 to move upward, so that the flush button is subjected to uniform force, which facilitates the timely resetting of the flush button and prevents the pressing column above the drain valve 22 from tilting during the pressing process.

[0046] As an embodiment of the present invention, the connecting member is a small first steel wire rope 25; the bottom end of the first steel wire rope 25 is fixedly connected to the upper surface of the float chamber 23, and the top end of the first steel wire rope 25 is fixedly connected to the surface of the movable rod 242 away from the drain valve 22;

[0047] During operation, the design of the connecting piece for the first steel wire rope 25 can effectively enhance the strength of the connecting piece, avoid the first steel wire rope 25 from breaking during repeated pulling, and simultaneously improve the service life of the connecting piece.

[0048] As an embodiment of the present invention, the surface of the first steel wire rope 25 is plated with a galvanized layer, and the outer surface of the first steel wire rope 25 is fixedly connected with a rubber sleeve;

[0049] During operation, since the first steel wire rope 25 is in contact with water for a long time inside the water tank 2, oxidation and rust are likely to occur on the surface of the first steel wire rope 25, thereby affecting the service life of the first steel wire rope 25. By applying a galvanized layer on the surface of the first steel wire rope 25, the corrosion resistance of the first steel wire rope 25 can be effectively improved. A rubber sleeve is fixedly connected to the outer surface of the first steel wire rope 25, so that the first steel wire rope 25 cannot be in direct contact with water, thereby effectively reducing the probability of oxidation and rust of the first steel wire rope 25 and simultaneously improving the service life of the first steel wire rope 25.

[0050] As an embodiment of the present invention, a transmission mechanism is fixedly connected to the bottom of the side wall of the float chamber 23 close to one end of the drain valve 22, and the transmission mechanism is used to assist the drain valve 22 in closing;

[0051] During operation, a transmission mechanism is fixedly connected to the bottom of the side wall of the float chamber 23. When the float chamber 23 moves downward, it drives the transmission mechanism downward. When the float chamber 23 moves downward to the bottom of the water tank 2, the transmission mechanism can accelerate the closing of the valve at the bottom of the drain valve 22, so that the water inside the water tank 2 cannot be discharged along the drain valve 22, effectively preventing the water inside the water tank 2 from continuously flushing the toilet, saving water, and reducing the waste of water resources.

[0052] As an embodiment of the present invention, the transmission mechanism includes: a sliding ring 31, the sliding ring 31 is sleeved on the surface of the support column 24;

[0053] A connecting plate 32, wherein the sliding ring 31 and the lower end of the side wall of the floating chamber 23 are fixedly connected with the connecting plate 32;

[0054] A second steel wire rope 33, the bottom end of which is fixedly connected to the upper surface of the sliding sealing plug at the bottom of the drain valve 22, and the second steel wire rope 33 passes through the side wall of the drain valve 22 and is fixedly connected to the sliding ring 31;

[0055] During operation, since the surface of the support column 24 is slidably connected with the sliding ring 31, a connecting plate 32 is fixedly connected between the sliding ring 31 and the bottom of the side wall of the float chamber 23, and a second steel wire rope 33 is fixedly connected to the upper surface of the sliding sealing plug at the bottom of the drain valve 22, the second steel wire rope 33 penetrates the side wall of the drain valve 22 and is fixedly connected to the sliding ring 31. When the float chamber 23 moves downward to the bottom of the water tank 2, the float chamber 23 drives the sliding ring 31 to move downward through the connecting plate 32. Since the sliding ring 31 and the sliding sealing plug at the bottom of the drain valve 22 are connected by the second steel wire rope 33, when the sliding ring 31 moves downward, the sliding sealing plug at the bottom of the drain valve 22 is forced to move upward to block the outlet of the drain valve 22, thereby effectively preventing the water inside the water tank 2 from continuously flowing out along the drain outlet to flush the toilet, thereby reducing the waste of water resources.

[0056] As an embodiment of the present invention, the length of the second steel wire rope 33 is designed corresponding to the sliding distance of the floating chamber 23;

[0057] During operation, the length of the second steel wire rope 33 is designed to correspond to the sliding distance of the float chamber 23. When the float chamber 23 moves downward to the bottom of the water tank 2, the second steel wire rope 33 drives the sliding sealing plug at the bottom of the drain valve 22 to close completely and timely, thereby effectively avoiding that the drain valve 22 is still in the drainage state when the float chamber 23 moves to the bottom of the water tank 2, further reducing the situation where the flush button is not reset in time and causes water waste.

[0058] The experimental steps are as follows:

[0059] In order to verify that the present invention can reduce the phenomenon that the toilet flush button cannot be reset in time to close the drain valve, resulting in the water in the water tank continuously flushing the toilet and seriously wasting water resources, the following experiment is conducted.

[0060] Experimental materials: alkaline solution, flow meter, ordinary toilet and toilet designed by the present invention, and the volumes of the two toilets are the same, and both toilets are water-saving toilets 3L / 6L.

[0061] Experimental process: flow meters are installed on ordinary toilets and toilets designed by the present invention, and then alkaline solutions are injected into the water tanks of the two toilets respectively. The 3L flush buttons of the two toilets are repeatedly pressed 20 times a day. Then, the flow meters are used to record the total amount of water used for flushing the two toilets every three days. The total amount of water used by the two toilets is counted for one month, and the average value is taken after repeated statistics three times, as shown in Table 1.

[0062] Table 1

[0063]

[0064] Experimental results: According to the experimental results, the total amount of water used by ordinary toilets is recorded more than that of the toilet designed by the present invention. As the use time increases, the total amount of water used by ordinary toilets each time shows an obvious increasing trend, while the total amount of water used by the toilet designed by the present invention each time increases more slowly, and the water-saving effect is relatively obvious. Therefore, the flush button of the toilet designed by the present invention can be reset in time, thereby effectively reducing the waste of water resources.

[0065] The specific operation process is as follows:

[0066] By installing an inlet valve 21 inside the water tank 2, the inlet valve 21 is connected to the water source, so that the water source flows into the space inside the toilet water tank 2 along the inlet valve 21. When the water level inside the water tank 2 reaches the set water storage volume, the inlet valve 21 automatically stops supplying water to the inside of the water tank 2. By providing a drain valve 22 inside the water tank 2, the water source inside the water tank 2 is discharged by pressing the flush button on the top of the drain valve 22 to flush the toilet. Since a suspension device is installed inside the water tank 2, the suspension device changes with the water level inside the water tank 2. Auxiliary devices are fixedly installed on both sides of the drain valve 22, and the auxiliary device is connected to the suspension device through a connecting piece. When the flush button is pressed, the water level inside the water tank 2 drops, and the suspension device inside the water tank 2 moves downward synchronously with the water level. When the suspension device moves downward to the bottom of the water tank 2, the end of the auxiliary device close to the drain valve 22 is driven to tilt upward by the connecting piece, and the auxiliary flush button is reset in time.

[0067] The suspension device is a float chamber 23 designed as a rectangular structure. The float chamber 23 can move with the change of the water level inside the water tank 2. A water inlet groove is opened in the middle of the surface of the float chamber 23 on one side close to the drain valve 22. When the water level inside the water tank 2 is higher than the height of the water inlet groove, the water inside the water tank 2 will enter the space inside the float chamber 23 along the water inlet groove, thereby increasing the gravity of the float chamber 23. When the flush button is pressed to flush the toilet, as the gravity of the float chamber 23 increases, the downward pulling force of the auxiliary device away from the drain valve 22 can be effectively increased, so that when the float chamber 23 moves to the bottom of the water tank 2, the auxiliary device is quickly driven through the connecting piece to assist the flush button to be reset in time to close the drain valve 22.

[0068] By fixing and connecting evenly arranged sliding rods 231 on the inner wall of the water tank 2, the float chamber 23 slides up and down along the length direction of the sliding rod 231. By the matching design of the sliding rod 231 and the float chamber 23, the sliding direction of the float chamber 23 is limited, so that the float chamber 23 cooperates with the connecting piece and the auxiliary unit in time to assist the flush button to be reset in time.

[0069] The two sides of the drain valve 22 are fixedly connected to uniformly arranged support columns 24, and the top surface of each support column 24 is fixedly connected to a uniformly arranged support frame 241, and a movable rod 242 is hinged between two adjacent support frames 241. The movable rod 242 extends to one end above the drain valve 22 and is fixedly connected to a fixed column 243. The movable rod 242 is fixedly connected to the float chamber 23 at one end away from the drain valve 22 through a connecting piece. When the moving distance of the float chamber 23 is greater than the length of the connecting piece, the movable rod 242 is driven to move downward away from the end of the drain valve 22, forcing the movable rod 242 to move upward close to the end of the drain valve 22, driving the fixed column 243 to move upward synchronously, and assisting in timely resetting the flush button.

[0070] The movable rod 242 is designed with a Y-shaped structure at one end near the drain valve 22, and is fixedly connected to an evenly arranged fixed column 243 at one end near the drain valve 22. When the movable rod 242 is subjected to force and tilted upward at one end near the drain valve 22, the movable rod 242 drives the fixed column 243 to move upward, so that the flush button is subjected to uniform force.

[0071] The first steel wire rope 25 is in contact with water inside the water tank 2 for a long time, and oxidation and rust are likely to occur on the surface of the first steel wire rope 25, thereby affecting the service life of the first steel wire rope 25. By applying a galvanized layer on the surface of the first steel wire rope 25, the corrosion resistance of the first steel wire rope 25 can be effectively improved. A rubber sleeve is fixedly connected to the outer surface of the first steel wire rope 25, so that the first steel wire rope 25 cannot be in direct contact with water.

[0072] A transmission mechanism is fixedly connected to the bottom of the side wall of the float chamber 23. When the float chamber 23 moves downward, it drives the transmission mechanism downward. When the float chamber 23 moves downward to the bottom of the water tank 2, the transmission mechanism can accelerate the closing of the valve at the bottom of the drain valve 22, so that the water inside the water tank 2 cannot be discharged along the drain valve 22.

[0073] A sliding ring 31 is slidably connected to the surface of the support column 24, and a connecting plate 32 is fixedly connected between the sliding ring 31 and the bottom of the side wall of the float chamber 23. A second steel wire rope 33 is fixedly connected to the upper surface of the sliding sealing plug at the bottom of the drain valve 22. The second steel wire rope 33 penetrates the side wall of the drain valve 22 and is fixedly connected to the sliding ring 31. When the float chamber 23 moves downward to the bottom of the water tank 2, the float chamber 23 drives the sliding ring 31 to move downward through the connecting plate 32. Since the sliding ring 31 and the sliding sealing plug at the bottom of the drain valve 22 are connected by the second steel wire rope 33, when the sliding ring 31 moves downward, the sliding sealing plug at the bottom of the drain valve 22 is forced to move upward to block the outlet of the drain valve 22.

[0074] By designing the length of the second steel wire rope 33 to correspond to the sliding distance of the float chamber 23, when the float chamber 23 moves downward to the bottom of the water tank 2, the second steel wire rope 33 drives the sliding sealing plug at the bottom of the drain valve 22 to be completely closed.

[0075] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
