Description

Technical Field

[0001] This utility model relates to the field of sanitary ware, and in particular to a toilet water replenishment device and a toilet. Background Technology

[0002] Currently, most toilet tank inlet valves on the market adopt a dual-channel design, including a main outlet channel and an auxiliary outlet channel. When the inlet valve is opened, both channels work simultaneously: the main outlet channel is mainly responsible for quickly replenishing water into the tank, while the auxiliary outlet channel is used to slowly fill the water trap (water seal) at the bottom of the toilet with water to maintain the odor-proof sealing level. However, due to limitations in structural design, the cross-sectional area of ​​the auxiliary outlet channel is usually significantly smaller than that of the main outlet channel, resulting in a severely insufficient water flow per unit time and slow water replenishment to the water trap; the slow water seal recovery speed can temporarily weaken the odor-proof function of the water trap, potentially causing odor backflow problems in the sewage pipe. Utility Model Content

[0003] This utility model addresses the technical problems existing in the prior art by providing a toilet water replenishment device and a toilet. Through structural optimization, it can significantly increase the water replenishment flow of the toilet water seal, enabling the toilet water seal to recover quickly and avoiding the problem of backflow of odor caused by delayed water replenishment.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: a toilet water replenishment device, including a water inlet mechanism, which has a water inlet channel, a first water outlet channel and a second water outlet channel, and can control whether the first water outlet channel and the second water outlet channel are connected to the water inlet channel; it also includes a switching mechanism, which includes a water storage chamber, a main water inlet, an auxiliary water inlet, a first water outlet, a second water outlet, a first control component and a second control component, wherein the first water outlet is connected to the toilet water seal, the second water outlet is connected to the toilet water tank, the main water inlet is connected to the first water outlet channel, and the auxiliary water inlet is connected to the second water outlet channel. The water outlet connects the second water outlet channel and the water storage chamber. The bottom of the water storage chamber is provided with a drain outlet, which is automatically controlled to open and close by the first control component. A first float is installed in the water storage chamber. The first float and the second control component form a linkage structure so that the up and down movement of the first float drives the second control component to switch the main water inlet to the first or second water outlet. When the first water outlet channel is connected to the water inlet channel, the second control component controls the main water inlet to connect to the first water outlet first and then to the second water outlet in order to replenish the toilet water seal and water tank.

[0008] In a preferred embodiment, the switching mechanism further includes a switching body, which is provided with the main inlet, the first outlet and the second outlet; the second control component includes a swing member, which is connected to the outside of the switching body and connected to the first float in a swinging manner, and the swing member is coaxially connected to a reversing member located inside the switching body.

[0009] In a preferred embodiment, the top of the first float is provided with an upwardly extending linkage rod, and the swing member and the linkage rod are rotatably connected through the insertion and connection of a hole and a shaft.

[0010] In a preferred embodiment, the oscillating member includes a first connecting portion and a second connecting portion distributed and fixed together along its length direction. The first connecting portion is coaxially connected to the reversing member. The second connecting portion is frame-shaped, and its opposite side walls are respectively provided with the holes arranged oppositely. The holes are elongated and extend along the length direction of their respective side walls. The top of the linkage rod enters the second connecting portion, and the top of the linkage rod is provided with the shaft corresponding to each of the holes. The shaft passes through the corresponding holes.

[0011] In a preferred embodiment, the switching mechanism further includes a small water tank, which has the water storage cavity, and the auxiliary water inlet is located in the small water tank or a connector provided on the small water tank; the small water tank is integrally formed or fixedly connected to the switching body.

[0012] In a preferred embodiment, the cross-sectional area of ​​the second water outlet channel is smaller than that of the first water outlet channel; the on / off states of the first and second water outlet channels are the same.

The water stop assembly is located on the valve body and controls the opening and closing of the water inlet channel. The second float is installed on the valve body and can move with the rise and fall of the water level in the water tank. It is linked with the water stop assembly to trigger the water stop assembly to open the water inlet channel when the water level in the water tank drops, and to trigger the water stop assembly to close the water inlet channel when the water level rises to a set height.

[0015] In a preferred embodiment, the switching mechanism is provided with a sleeve that extends vertically and is fitted onto the overflow pipe.

[0016] This utility model also provides a toilet, including a toilet body and a water tank disposed on the toilet body, and also includes the toilet flushing and water replenishment device as described in this utility model above.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. This utility model also includes the aforementioned switching mechanism. When the first water outlet channel of the water inlet mechanism is connected to the water inlet channel, the second control component of the switching mechanism controls the main water inlet to first connect with the first water outlet, and then with the second water outlet, so as to replenish the toilet water seal and the water tank sequentially. This allows the first water outlet channel of the water inlet mechanism, which was originally used to replenish the water tank, to first replenish the toilet water seal and then replenish the toilet water tank. This design enables the toilet water seal to recover quickly, preventing feces from sticking to the toilet ceramic body during the water seal recovery period, making it easy to clean and maintaining long-term hygiene; it can shorten the water seal recovery time, ensuring that the toilet trap always maintains an effective seal, preventing odor leakage, and improving user comfort. In addition, the switching mechanism of this application utilizes the linkage between the first float and the second control component as the driving force for the second control component, eliminating the need for additional driving force, making it more energy-efficient and environmentally friendly, and ensuring the reliability and stability of the device operation. Therefore, this utility model optimizes the water replenishment process of traditional toilets by rationally allocating the water inlet path, solves the hygiene problems caused by the delayed water seal recovery, and achieves a dual improvement in energy saving and functionality.

[0019] 2. As a preferred embodiment, the first control component adopts a combination structure of a counterweight and a reset component. The automatic closing control of the drain outlet is achieved by the gravity of the counterweight applied by the water flow. This structure utilizes the kinetic energy of the water itself as the driving force source, eliminating the need for additional driving force, thus being more energy-efficient and environmentally friendly. Furthermore, it features a simple structure, convenient maintenance, and rapid response, enabling precise opening and closing control of the drain outlet. Therefore, this design of the present invention achieves functional requirements through ingenious mechanical principles, conforming to the trend of energy conservation and environmental protection while reducing the complexity of the device, making it particularly suitable for energy-sensitive bathroom equipment scenarios.

[0020] 3. The cross-sectional area of ​​the second water outlet channel is smaller than that of the first water outlet channel, resulting in a larger flow rate in the first water outlet channel. This allows for rapid water replenishment of the toilet water seal, improves the water tank filling efficiency, and shortens the flushing cycle. Preferably, the water inlet mechanism can be implemented using a conventional mechanical inlet valve. Through the synergistic effect of water pressure and mechanical structure, the water inlet process can be completed without an additional power source. Therefore, the water inlet mechanism can be implemented using the inlet valve already present in a traditional toilet tank.

[0021] 4. The switching mechanism is located on the overflow pipe of the drain valve, and the first outlet of the switching mechanism is connected to the toilet water seal through this overflow pipe. This design not only directly utilizes the overflow pipe as the installation carrier of the switching mechanism and the connecting channel of the first outlet, saving additional installation space and parts, but also makes the overall structure more compact and reasonable. This design retains the original function of the overflow pipe and gives it a new purpose as a water seal replenishment channel, significantly simplifying the water circuit layout inside the toilet by sharing the pipeline. In practical applications, this solution not only shortens the water seal replenishment path and improves replenishment efficiency, but also reduces pipe connection points and lowers the risk of leakage, while not affecting the normal operation of the drain valve at all. Preferably, the switching mechanism is installed by a sleeve connecting to the overflow pipe, which has good structural reliability and is easy to install, without requiring drilling, cutting, or other destructive sealing of the overflow pipe.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments; however, the toilet water replenishment device and toilet of the present invention are not limited to the embodiments. Attached Figure Description

[0036] In this utility model, the terms "first," "second," etc., are used only to distinguish similar objects, not to describe a specific order or sequence, nor should they be construed as indicating or implying relative importance. The use of terms such as "upper," "lower," "inner," "outer," and "top / bottom" to indicate orientation or positional relationships is based on the orientation or positional relationships shown in the accompanying drawings, and is solely for the convenience of describing this utility model, not to indicate or imply that the device referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the scope of protection of this utility model. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0037] Furthermore, in the description of this utility model, "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. The character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0038] Please see Figures 1-11 As shown, a toilet water replenishment device of this utility model includes a water inlet mechanism and a switching mechanism 2. The water inlet mechanism is provided with a water inlet channel 11, a first water outlet channel 12 and a second water outlet channel 13, and can control whether the water inlet channel 11 is connected to the first water outlet channel 12 and the second water outlet channel 13. The on / off states of the first water outlet channel and the second water outlet channel 13 are the same, that is, when the first water outlet channel 12 is connected to the water inlet channel 11, the second water outlet channel 13 is also connected to the water inlet channel 11, and when the first water outlet channel 12 is not connected to the water inlet channel 11, the second water outlet channel 13 is also not connected to the water inlet channel 11.

[0039] This utility model also includes a switching mechanism 2, which includes a water storage chamber 261, a main water inlet 211, an auxiliary water inlet 281, a first water outlet 212, a second water outlet 213, a first control component, and a second control component. The first water outlet 212 is connected to the toilet water seal, and the second water outlet 213 is connected to the toilet tank 7. The main water inlet 211 is connected to the first water outlet channel, and the auxiliary water inlet 281 is connected to the second water outlet channel 13 and the water storage chamber 261, so that when water flows out of the second water outlet channel 13, water can flow into the auxiliary water inlet 281, and then into the water storage chamber 261 through the auxiliary water inlet 281. A drain outlet 262 is provided at the bottom of the water storage chamber 261, and the drain outlet 262 is automatically controlled to open and close by the first control component. A first float 27 is installed inside the water storage chamber 261. This first float 27 forms a linkage structure with a second control component, so that the up-and-down movement of the first float 27 drives the second control component to switch the connection between the main inlet 211 and either the first outlet 212 or the second outlet 213. Specifically, in the initial state (where the first float 27 is submerged), the second control component connects the main inlet 211 to the first outlet 212. When the first float 27 rises, it triggers the second control component to connect the main inlet 211 to the second outlet 213. When the first outlet channel is connected to the inlet channel, the second control component controls the main inlet 211 to first connect to the first outlet 212, and then to the second outlet 213, thereby replenishing the toilet water seal and the water tank 7 sequentially. Therefore, the water inlet mechanism of this invention, originally designed to replenish water to the water tank 7 via the first water outlet channel 12, can first replenish the toilet water seal and then replenish the toilet water tank 7. This design enables the toilet water seal to recover quickly, solving the hygiene problems caused by delayed water seal recovery.

[0040] In a preferred embodiment, the first control component includes a counterweight 22 and a reset component. The counterweight 22 is vertically detachable within the water storage chamber 261 and is positioned at the drain outlet 262. The counterweight 22 blocks the drain outlet 262 by lowering the water level. An auxiliary water inlet 281 connects to the counterweight 22, and the counterweight 22 replenishes the water storage chamber 261 through overflow. Specifically, when water enters through the auxiliary water inlet 281, water first enters the counterweight 22. Once the water level exceeds the maximum water level line of the counterweight 22, the excess water then enters the water storage chamber 261. A drain hole 221 is provided at the bottom of the counterweight 22. The cross-sectional area B of this drain hole 221 is smaller than the cross-sectional area A of the auxiliary water inlet 281, allowing the water level in the counterweight 22 to gradually rise and the water volume to gradually increase as water enters. The drain hole 221 and the drain outlet 262 are positioned correspondingly, meaning that the drain hole 221 and the drain outlet 262 are spatially aligned, allowing water discharged from the drain hole 221 to pass through the drain outlet 262. A reset component is located between the counterweight tank 22 and the water storage chamber 261, used to drive the counterweight tank 22 to reset upwards to open the drain outlet 262.

[0041] The drain outlet 262 and the drain hole 221 connect to the toilet tank 7. The inner diameter of the drain hole 221 is smaller than the inner diameter of the drain outlet 262. The drain hole 221 is formed by the inner cavity of a small tube 222 extending downward from the bottom wall of the counterweight barrel 22. The height h of the tube is greater than 10mm. In the reset state of the counterweight barrel 22, the bottom end of the small tube 222 is flush with the top end of the drain outlet 262, or the small tube 222 partially enters the drain outlet 262. This design helps to improve the drainage speed of the counterweight barrel 22.

[0042] Furthermore, the water storage chamber 261 includes a first chamber 2611 and a second chamber 2622 that are laterally connected. A counterweight 22 is disposed in the first chamber 2611, which guides the vertical movement of the counterweight 22. A first float 27 is disposed in the second chamber 2622, which guides the vertical movement of the first float 27. A drain outlet 262 is located on the bottom wall of the first chamber 2611, and an auxiliary inlet 281 is located on the top of the first chamber 2611, with its outlet direction downwards towards the counterweight 22. A reset member is disposed between the outer bottom of the counterweight 22 and the bottom wall of the first chamber 2611. The reset member is preferably an elastic element; in this embodiment, a helical spring 24 is used as an example, but it is not limited to this. In other embodiments, the reset member includes a magnetic component, which includes magnets that attract each other magnetically to drive the counterweight 22 upwards.

[0043] The switching mechanism 2 also includes a switching body 21, which has a main inlet 211, a first outlet 212 and a second outlet 213. The second control component includes a swing member 23, which is connected to the outside of the switching body 21 and connected to a first float 27. The swing member 23 is coaxially connected to a reversing member 25 located inside the switching body 21. The first float 27 drives the swing member 23 to swing by moving up and down, so that the reversing member 25 closes the first outlet 212 or the second outlet 213.

[0044] Preferably, the oscillating member 23 is connected to the first float 27 in the following manner: the top of the first float 27 is provided with an upwardly extending linkage rod 271, and the oscillating member 23 and the linkage rod 271 are rotatably connected through the insertion and engagement of holes 233 and shafts 272. Specifically, the oscillating member 23 includes a first connecting part 231 and a second connecting part 232 distributed and fixed together along its length direction. The first connecting part 231 is coaxially connected to the reversing member 25. The second connecting part 232 is frame-shaped, and its opposite side walls are respectively provided with oppositely arranged holes 233. The holes 233 are elongated and extend along the length direction of their respective side walls. The top of the linkage rod 271 enters the second connecting part 232, and the top of the linkage rod 271 is provided with a shaft 272 corresponding to each hole 233, and the shaft 272 passes through the corresponding hole 233.

[0045] The reversing component 25 is used to switch the opening of the first outlet 212 and the second outlet 213 by rotation. Specifically, the reversing component 25 includes a reversing plate 251 and a sealing gasket 252, with the sealing gasket 252 fitted onto one side of the reversing plate 251 in its thickness direction. One end of the reversing plate 251 is provided with a rotating shaft 253, which is integrally formed with the reversing plate. The rotating shaft 253 is inserted into the first connecting part of the swing member 23 along one side of its width direction, enabling the reversing component 25 and the swing member 23 to rotate synchronously. The switching body 21 is composed of a switching seat 214, a seat cover 215, and a small cover 217. The seat cover 215 has a shaft hole 216 corresponding to the rotating shaft 253 for the rotating shaft 253 to pass through. The main inlet 211, the first outlet 212, and the second outlet 213 are respectively located on the switching seat 214. The inlet end of the main inlet 211 is set downward and the outlet end is set horizontally; the inlet end of the first outlet 212 is set horizontally and the outlet end is set downward; the inlet end of the second outlet 213 is set upward and the outlet end is set downward.

[0046] The switching mechanism 2 also includes a small water tank 7, which has a water storage chamber 261. An auxiliary water inlet 281 is located at the connector 28 connected to the top of the small water tank 7, but this is not limited to this. In other embodiments, the auxiliary water inlet 281 is directly located in the small water tank 7. The inlet end of the auxiliary water inlet 281 extends laterally and connects to the second water outlet channel 13. The outlet end of the auxiliary water inlet 281 is set downward and corresponds to the counterweight barrel 22, so that when water is discharged from the auxiliary water inlet 281, the water flow can fall directly into the counterweight barrel 22. The small water tank 7 is integrally formed or fixedly connected to the switching body 21. In this embodiment, the small water tank 7 is fixedly connected to the switching seat 214 of the switching body 21 as an example, but this is not limited to this.

[0047] The cross-sectional area of ​​the second water outlet channel 13 is smaller than that of the first water outlet channel 12, resulting in a larger flow rate in the first water outlet channel 12. This allows for rapid water replenishment of the toilet water seal, while also improving the water filling efficiency of the tank 7 and shortening the flushing cycle. The water inlet mechanism is preferably a conventional mechanical water inlet valve 1, which is located inside the tank 7. In other embodiments, the water inlet mechanism can be replaced by a solenoid valve, in which case the solenoid valve can have the aforementioned water inlet channel 11, first water outlet channel 12, and second water outlet channel 13. The inlet valve 1 specifically includes a valve body 14, a water-stopping assembly 15, and a second float 16. The valve body 14 has an inlet channel 11, a first outlet channel 12, and a second outlet channel 13. The water-stopping assembly 15 is located on the valve body 14 and controls the opening and closing of the inlet channel 11. The second float 16 is installed on the valve body 14 and can move with the rise and fall of the water level in the water tank 7. It is linked with the water-stopping assembly 15 so that when the water level in the water tank 7 drops, the water-stopping assembly 15 is triggered to open the inlet channel 11, and when the water level rises to a set height, the water-stopping assembly 15 is triggered to close the inlet channel 11. The first outlet channel 12 is located on the bottom side of the valve body 14 and is connected to the main inlet 211 of the switching mechanism 2 through a first water pipe 4. The second outlet channel 13 is located on the top side of the valve body 14 and is connected to the auxiliary inlet 261 of the switching mechanism 2 through a second water pipe 5.

[0048] The toilet tank 7 is equipped with a drain valve 3. A switching mechanism 2 is located on the overflow pipe 31 of the drain valve 3, and the first outlet 212 is connected to the toilet water seal through the overflow pipe 31 to replenish the toilet water seal. Specifically, the switching mechanism 2 is equipped with a sleeve 29, which is fitted onto the overflow pipe 31 to achieve a fixed connection between the switching mechanism 2 and the overflow pipe 31. However, the connection method between the switching mechanism 2 and the overflow pipe 31 is not limited to this. In other embodiments, the connection between the switching mechanism 2 and the overflow pipe 31 can be achieved by using hooks, screw fastening, snap-fit ​​connection, threaded connection, snap ring connection, etc. The sleeve 29 is integrally formed or fixedly connected to the aforementioned small water tank 7. In this embodiment, the sleeve 29 is integrally formed with the small water tank 7. The sleeve 29 is fitted over the overflow pipe 31, and the inner side of the sleeve 29 is provided with limiting ribs 291 to achieve a tight fit between the sleeve 29 and the overflow pipe 31. Specifically, the limiting ribs 291 extend circumferentially along the sleeve 29 to form a ring structure, and the number of limiting ribs 291 can be one or more. In this embodiment, three are used as an example, but it is not limited to this. Furthermore, the top opening of the sleeve 29 can be set into a constricted shape to form an inner flange for abutting against the top surface of the overflow pipe 31, thereby improving the stability of the sleeve 29 on the overflow pipe 31.

[0049] This utility model discloses a toilet water replenishment device, which can be applied to toilets, especially conventional ordinary toilets, such as... Figure 12 As shown. The working principle of this utility model is as follows:

[0050] Before the inlet valve 1 is activated, the weight G of the counterweight 22 is less than the preload F of the spring 24, the counterweight 22 is in its highest position, and the drain outlet 262 is open; the reversing component 25 closes the second outlet 213, and the first outlet 212 is open. Figure 6 As shown. When the toilet tank 7 is emptied and the inlet valve 1 is activated, the first outlet channel 12 and the second outlet channel 13 are both connected to the inlet channel 11. Most of the water flows through the first outlet channel 12 to the main inlet 211, and then sequentially through the first outlet 212, sleeve 29, and overflow pipe 31 into the toilet water seal. Figure 7 As shown. Simultaneously, a small portion of water flows from the second outlet channel 13 into the auxiliary inlet 261 and into the counterweight tank 22, causing water to slowly accumulate in the counterweight tank 22. (As shown...) Figure 8 As shown, when the sum of the weight G of the counterweight barrel 22 and the weight G1 of the water stored in the counterweight barrel 22 is greater than the elastic force F1 of the spring 24, the counterweight barrel 22 moves downward until the drain outlet 262 is closed; when the water stored in the counterweight barrel 22 exceeds the highest water level of the counterweight barrel 22, the water in the counterweight barrel 22 overflows into the part of the water storage chamber 261221 outside the counterweight barrel 22, thereby causing the water storage chamber 261 to start storing water, as shown. Figure 9As shown, as the water level in the storage chamber 261 gradually rises, the first float 27 gradually rises, thereby pushing the swing member 23 to swing upwards, causing the reversing member 25 to rotate and realize the water circuit switching. That is, the reversing member 25 closes the first outlet 212 and opens the second outlet 213. At this time, the toilet water seal replenishment ends, and the water output from the first outlet channel 12 flows out from the second outlet 213 and falls into the toilet tank 7. Figure 10 As shown. Simultaneously, water continuously enters through the auxiliary inlet 261 to maintain the water level in the counterweight tank 22 and the water storage chamber 261, thereby ensuring that the first outlet 212 is closed. Water discharged from the counterweight tank 22 through the drain hole 222 falls into the water tank 7, providing a certain amount of replenishment to the water tank 7.

[0051] When the water level in the water tank 7 rises to the set level, the inlet valve 1 stops supplying water, and both the first outlet channel 12 and the second outlet channel 13 of the inlet valve 1 stop discharging water. The water in the counterweight barrel 22 is gradually drained through the drain hole 222. When the sum of the weight G of the counterweight barrel 22 and the weight G1 of the water is less than the elastic force F1 of the spring 24, the spring 24 drives the counterweight barrel 22 to return to its original position, thereby opening the drain outlet 262. The water in the water storage chamber 261 is discharged into the toilet tank 7 through the drain outlet 262. As the water level in the water storage chamber 261 drops, the first float 27 gradually sinks, driving the swing element 23 to rotate the reversing element 25 to achieve water circuit switching, keeping the first outlet 212 open, in preparation for the next water replenishment.

[0052] Therefore, the toilet water replenishment device of this utility model can realize rapid drainage of the toilet water seal, allowing the toilet water seal to recover quickly. It can effectively buffer the impact of excrement, prevent excrement from directly contacting the ceramic wall during the water seal recovery period, reduce the probability of adhesion, facilitate cleaning and maintain long-term hygiene; it can shorten the water seal recovery time, ensure that the toilet water trap always maintains an effective seal, avoid odor overflow, and improve the comfort of use.
