Description

Technical Field

[0001] The utility model relates to the field of bathrooms, and more particularly to a water tank assembly, a flushing system and a toilet. Background Art

[0002] Smart toilet water circuits are typically controlled using a point-to-point, line-to-line approach. After the water circuits are separated from the angle valve, the smart toilet flushing circuit and the smart toilet lid cleaning circuit are used separately. Independent water circuit control has its advantages, such as simple connection logic and no need to consider other related application relationships. However, it has the disadvantage of requiring more connecting pipes and components between modules, which increases the installation space required.

[0003] Furthermore, independent waterway control also results in the related functional components performing a single function, failing to effectively improve component utilization and resulting in wasted control panel resources. For example, the water inlet module controls the water inlet to the smart toilet lid cleaning system and the smart toilet flushing system, and normally these functions are staggered, preventing simultaneous use of both functions. However, when each is independent, the functions they perform are very limited, and a single waterway system requires two water inlet modules, resulting in wasted resources. Utility Model Content

DETAILED DESCRIPTION

[0041] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other in any way.

[0042] like Figures 1-8 As shown, an embodiment of the present invention provides a water tank assembly 100 that can be used in a sitting or squatting toilet and supply water to the toilet.

[0043] like Figure 1 、 Figure 2 As shown, the water tank assembly 100 of the present invention includes a water tank body 10, a floating water inlet valve 3 and a water inlet linkage assembly 4. The water tank body 10 has a water storage chamber and a partition 11 that separates the water storage chamber into a first water tank 1 and a second water tank 2.

[0044] like Figure 2-Figure 4 As shown, the second water tank 2 is provided with an overflow port 20 communicating with the first water tank 1, allowing water from the second water tank 2 to overflow into the first water tank 1. A floating water inlet valve 3 is used to supply water to the second water tank 2 and includes a first floating member 31 that floats with the water level in the second water tank 2 to control the water inlet state of the floating water inlet valve 3. A water inlet linkage assembly 4 is provided in the first water tank 1 and is configured to float with the water level in the first water tank 1, cooperating with the first floating member 31 to control the water inlet state of the floating water inlet valve 3.

[0045] The water tank assembly 100 of the embodiment of the present invention is configured to allow water to enter the first water tank 1 through overflow from the second water tank 2, thereby reducing the number of water inlet components, reducing the complexity of connections and controls, and reducing costs and saving space. Moreover, the water tank assembly 100 of the embodiment of the present invention is configured to provide a water inlet linkage assembly 4 in the first water tank 1 that cooperates with the floating water inlet valve 3, thereby providing feedback and controlling the water level in the first water tank 1, so that the buoyant water inlet valve 3 indirectly controls the water inlet of the first water tank 1, thereby achieving control of the water inlet and water level of the first water tank 1 and the second water tank 2, and achieving the purpose of continuous water use. Furthermore, the two water tanks are separated by an integrated box body, thereby saving space and reducing manufacturing difficulty and costs.

[0046] like Figure 4 As shown, the floating water inlet valve 3 in this embodiment includes a valve body 30 and a first floating member 31 mounted on the valve body 30. The buoyant water inlet valve 3 can be a float valve, a ball valve, or other control valve that utilizes the floating principle of a floating member to achieve on-off control. The first floating member 31 can be a float or a floating ball mounted on the valve body 30, which can control the operating state of the buoyant water inlet valve. For example, when the first floating member 31 is at a high water level, the buoyant water inlet valve is closed; when the first floating member 31 is at a low water level, the buoyant water inlet valve is opened. This article mainly uses the floating water inlet valve 3 as a buoyant water inlet valve for detailed description.

[0047] like Figure 2 As shown, the buoyancy inlet valve 3 of this embodiment is disposed within the second water tank 2. A water inlet port 203 is provided at the bottom of the second water tank 2, which is compatible with the buoyancy inlet valve 3. This facilitates flexible installation of the water tank assembly 100. Of course, the buoyancy inlet valve 3 can also be partially disposed outside the second water tank 2, which is not limited here. The water inlet port 203 can also be disposed at other locations within the second water tank 2, which is not limited here.

[0048] The water inlet linkage assembly 4 of the utility model embodiment includes a first working state (refer to FIG. 1 ) which cooperates with the first floating member 31 to open the buoyant water inlet valve 3. Figure 5 ) and release the second working state of the buoyancy inlet valve 3 (reference Figure 7 ).

[0049] In the embodiment of the present invention, the water inlet linkage assembly 4 switches between a first operating state and a second operating state under the interaction of its own weight and the change in the water level of the first water tank 1. For example, when the water level in the first water tank 1 rises, the water inlet linkage assembly 4 is pushed upward, releasing its action on the first floating member 31. Here, the buoyant water inlet valve 3 can be in a closed state or in an open state to replenish water to the second water tank 2. When the water level drops, the water inlet linkage assembly 4 descends under the action of its own weight, thereby driving the first floating member 31 to open the floating water inlet valve 3 and replenish water to the first water tank 1.

[0050] In another exemplary embodiment, the water tank assembly 100 further includes a reset element (not shown) that provides a reset force for the water inlet linkage assembly 4. The water inlet linkage assembly 4 switches between the first operating state and the second operating state under the interaction of the reset element and the change in the water level of the first water tank 1. The reset element can be a reset spring, etc.

[0051] like Figure 3 、 Figure 4 As shown, the water inlet linkage assembly 4 includes a second floating member 41 and a connecting rod 42 that can float up and down following the change of the water level in the second water tank 2. One end of the connecting rod 42 cooperates with the first floating member 31, and the other end is connected to the second floating member 41. In the first working state, the connecting rod 42 presses against the first floating member 31 (see FIG. Figure 5 ), driving the floating water inlet valve 3 to open and replenish water; in the second working state, the connecting rod 42 releases the first floating member 41 (refer to Figure 7 ), no force is generated on the floating water inlet valve 3.

[0052] like Figure 4 As shown, in this embodiment, the second floating member 41 is provided with a mounting groove 410, and the connecting rod 42 is inserted into the mounting groove 410 and assembled with the second floating member 41. Of course, the second floating member 41 and the connecting rod 42 can also be formed integrally, and this is not limited here. In this embodiment, the second floating member 41 is a float, but it can also be a float ball, and this is not limited here.

[0053] In this embodiment, the first water tank 1 is smaller than the second water tank 2. Of course, the first water tank 1 and the second water tank 2 may also be the same size, or the first water tank 1 may be larger than the second water tank 2, which is not limited here.

[0054] like Figure 5 As shown, the second water tank 2 comprises a main cavity 21 and an auxiliary cavity 22 arranged side by side. The main cavity 21 is adjacent to the first water tank 1. The bottom of the auxiliary cavity 22 is higher than that of the main cavity 21. The buoyant water inlet valve 3 is mounted in the auxiliary cavity 22, with the first floating member 31 extending into the main cavity 22. The auxiliary cavity 22 supports the buoyant water inlet valve 3 at a certain height, so that the first floating member 31 of the buoyant water inlet valve 3 is located above the second water tank 2, ensuring that the second water tank 2 can be filled with the appropriate amount of water.

[0055] like Figure 3 As shown, the first water tank 1 of the present embodiment is provided with a guide portion, along which the water inlet linkage assembly 3 can be raised and lowered by the action of water flow. The inner wall of the first water tank 1 is provided with guide ribs 12. The space between the guide ribs 12 and the partition 11 forms a guide portion, and the connecting rod 41 of the water inlet linkage assembly 3 is assembled with the guide portion.

[0056] like Figure 3As shown, the buoyant water inlet valve 3 also includes a housing 32 that accommodates the first floating member 31. A stopper 320 is provided on the bottom wall of the housing 32. The first floating member 31 is movably connected to the stopper 320. The stopper 32 controls the vertical movement of the first floating member 31 and the height of its rise, thereby preventing water from overflowing.

[0057] like Figure 4 As shown, the second water tank 2 has an upper port, through which the floating water inlet valve 3 extends. The water tank assembly 100 also includes a cover 202 that cooperates with the second water tank 2 to cover and shield the upper port. The cover 202 prevents dust and debris from entering the second water tank 2, thereby ensuring the cleanliness of the second water tank 2.

[0058] The water tank assembly 100 also includes a liquid level detection element 2021 and a water outlet pipe 2022 provided on the cover body 202 and extending into the second water tank 2. The liquid level detection element 2021 is configured to detect the liquid level of the second water tank 2, thereby monitoring the water level of the second water tank 2 to prevent water shortage operation.

[0059] like Figure 5-Figure 8 As shown, when the water tank assembly 100 of the embodiment of the present invention is working, in the initial state, there is no water in the first water tank 1 and the second water tank 2, the buoyancy water inlet valve 3 is opened under the gravity of the first floating member 31, and the buoyancy water inlet valve 3 begins to take in water to replenish the water in the second water tank 2 (see FIG. Figure 5 At this time, the water inlet linkage assembly 4 presses the first floating member 31 under the action of its own gravity, driving the first floating member 31 to keep the floating water inlet valve 3 open. When the water in the second water tank 2 reaches the overflow level, the water flows into the first water tank 1 from the overflow port 20 to replenish the first water tank 1 (see Figure 6 When the water level continues to rise to a level that can drive the water inlet linkage assembly 4 to move upward until the water inlet linkage assembly 4 releases the pressure on the first floating member 31, the first floating member 31 floats up under the action of the water flow, closing the buoyancy water inlet valve 3, and then stopping the water replenishment of the entire water tank assembly 100 (see Figure 7 ).

[0060] like Figure 8 As shown, when the water in the first water tank 1 is used, the water level drops. At this time, regardless of whether the water in the second water tank 2 is used, the water inlet linkage assembly 4 presses the first floating member 31 under the action of its own weight to drive the first floating member 31 to keep the buoyancy water inlet valve 3 open, so that the second water tank 2 replenishes water for the first water tank 1.

[0061] When the first water tank 1 is full of water, but the water in the second water tank 2 is being used, the water level drops. At this time, the water inlet linkage assembly 4 releases the pressure on the first floating member 31, so that the first floating member 31 can float freely to control the buoyancy water inlet valve 3 to replenish water to the second water tank 2 or stop replenishing water.

[0062] The water tank assembly 100 of the present invention utilizes the water level changes in the water tank and the water inlet linkage assembly 4 to control the opening and closing of the buoyancy water inlet valve 3, thereby achieving the function of replenishing water to the two water tanks. This eliminates the need for a solenoid valve or motor control to achieve water inlet control, resulting in low cost. The design of the water inlet linkage assembly 4 of the present invention allows for continuous water supply to the two water tanks.

[0063] The water tank assembly 100 of the present invention utilizes the water level changes in the water tanks and the water inlet linkage assembly 4 to control the first floating member 31 of the floating water inlet valve 3, thereby achieving continuous water supply to both water tanks. This eliminates the need for a solenoid valve or motor, resulting in a simple connection and low cost. The design of the water inlet linkage assembly 4 of the present invention allows for continuous water replenishment of the two water tanks.

[0064] like Figure 10-13 As shown, the embodiment of the present invention also provides a flushing system, including the water tank assembly 100 as described in any of the above embodiments, a toilet flushing system ( Figure 12 ) and human body cleaning system ( Figure 13 ).

[0065] like Figure 13 As shown, the human body washing system is connected to the second water tank 2 of the water tank assembly 100 and includes a first pressurizing device 61, a heating device 62, and a cleaning device 63. The first pressurizing device 61 pressurizes the water in the second water tank 2 and then delivers it to the cleaning device 63 for human body washing. The heating device 62 heats the water in the second water tank 2 and then supplies it to the cleaning device 63. The cleaning device 63 is a device for human body washing. The specific structure can be referred to in the prior art and will not be described here in detail.

[0066] The controller of the flushing system controls the liquid level detection element 2021 to determine whether the liquid level in the second water tank 2 is normal and whether water has entered the second water tank 2. If the liquid level is normal (the liquid level is greater than or equal to the predetermined liquid level), the controller controls the first adding device 61 to extract the water stored in the second water tank 2 and provide it to the heating device 62 and the cleaning device 63 connected to the water outlet of the heating device 62, and then starts the heating device 62 and the cleaning device 63 to realize the cleaning function. If the detected liquid level is abnormal (the liquid level is less than the predetermined liquid level or is less than the predetermined liquid level for a predetermined time), the controller of the flushing system controls the human body cleaning system to shut down and issue a water shortage alarm to prevent the heating device 62 from drying out and being damaged.

[0067] like Figure 12As shown, the toilet flushing system connects the first water tank 1 of the water tank assembly 100 to the siphon port and brush ring port (not shown) of the toilet 300 for flushing. The toilet flushing system includes a second pressurizing device 71, a water distribution valve 72, a siphon nozzle 73, and a brush ring nozzle 74. The second pressurizing device 71 increases the water output from the first water tank 1 and supplies it to the water distribution valve 72, which then splits the water into two channels, supplying them to the siphon nozzle 73 and brush ring nozzle 74, respectively, to flush the toilet 200.

[0068] like Figures 9-13 As shown, the embodiment of the present invention further provides a toilet 200 including a toilet body, a water tank assembly 100 or a flushing system as described in any of the above embodiments and assembled with the toilet body. The first water tank 1 of the water tank assembly 100 can be a flushing water tank, which can be used to supply water to the brush ring interface and siphon interface of the toilet to provide flushing water. The second water tank 2 of the water tank assembly 100 can be a cleaning water tank, which can be used to supply water to the cleaning device 63 of the toilet to provide cleaning water. The flushing system includes a toilet flushing system ( Figure 12 ) and human washing system ( Figure 13 ).

[0069] The two water tanks of the water tank assembly 100 of the embodiment of the utility model can supply water to the toilet flushing system of the human body cleaning system respectively, and can match the water replenishment of the two systems according to different water use conditions, reducing functional components, reducing the complexity of connection and control, and reducing costs and saving space.
