However, to the extent that the method or process does not rely on the specific order of the steps described herein, the method or process should not be limited to the steps of the specific order described. As will be understood by those of ordinary skill in the art, other sequences of steps are also possible. Therefore, the specific sequence of the steps set forth in the specification should not be interpreted as a limitation to the claims.

[0029] like Figure 1-Figure 4 As shown, the embodiment of the present application provides a first water tank 1, comprising: a water tank body 10, the water tank body 10 comprising a water storage chamber 11 and a functional water chamber 12 isolated from each other, the water storage chamber 11 and the functional water chamber 12 being connected via a first water port 101. The functional water chamber 12 is configured to store functional water produced by the functional water production device 2.

[0030] The first water tank 1 of the embodiment of the present application can reduce the usage rate of the functional water generating device 2 and increase the service life of the functional water generating device 2 by providing a separate functional water chamber 12 .

[0031] The first water tank 1 also includes a functional water generating device 2 which can be installed in conjunction with the water tank body 10. The functional water generating device 2 can be a scale inhibitor, an electrolysis device, a sterilization device, a microbubble device, etc. In this embodiment, a scale inhibitor is used for detailed description.

[0032] When the functional water generating device 2 is a scale inhibitor, since the scale inhibitor is placed in the water tank, the scale inhibitor will be slowly released in the water until it reaches a saturated state. When there is too much water in the water tank, the slow release time and the amount of water released will increase, resulting in a reduced service life of the scale inhibitor. By isolating the functional water chamber 12 in the first water tank 1, when the water in the functional water chamber 12 is released to saturation, the scale inhibitor will reduce the release rate without having to release the water in the entire first water tank 1 to a saturated state, thereby increasing the service life of the scale inhibitor.

[0033] In addition, by isolating the water storage chamber 11 from the functional water chamber 12, it is possible to prevent the air accompanying the incoming water from being sucked into the heating chamber of the heating device 63 of the human body washing system A connected to the functional water chamber 12 when the first water tank 1 is operating while inletting and outlet water (see Fig.10 ), causing water level fluctuations during the cleaning process.

[0034] like Figure 4As shown, the water storage chamber 11 and the functional water chamber 12 are separated by a partition 13. The first water inlet 101 is provided on the partition 13, and is located at the bottom of the partition 13 and is higher than the bottom wall of the water storage chamber 11. Therefore, it is not only possible to disturb the water flow of the functional water chamber 12 in the process of the water from the water storage chamber 11 flowing into the functional water chamber 12, but also to prevent the precipitation of impurities in the functional water chamber 12. Moreover, the drop between the first water inlet 101 and the bottom of the water storage chamber 11 can be used to precipitate or store impurities or sand brought in from the pipeline during the water intake process, so as to maximize the guarantee that the impurity deposition in the functional water chamber 12 during long-term use will not enter the human body cleaning system A connected to the first box body 1, effectively protect the human body cleaning system A, and ensure the cleanliness of the cleaning water flow.

[0035] like Figure 5 As shown, the water storage chamber 1 is provided with a water inlet valve 5 (see Fig.10 ) is connected to the water inlet 102, which is arranged at the bottom of the water storage chamber 1, so that when water is taken in, the water flow can be disturbed to prevent impurities from settling in the water storage chamber 1. The functional water chamber 12 is also provided with a water outlet (not shown), which is arranged on the bottom wall of the functional water chamber 12, so that the water in the first box body 1 can be used in the largest amount.

[0036] like Figure 5 As shown, the first water tank 1 of the embodiment of the present application further includes a buoyancy level switch 3 and a baffle 14 provided in the water storage chamber 11. The buoyancy level switch 3 is configured to be connected to the water inlet valve 5 that supplies water to the first water tank 1 and to control the working state of the water inlet valve 5. The water storage chamber 11 is provided with the above-mentioned water inlet 102, and the baffle 14 separates the location of the water inlet 102 from the location of the buoyancy level switch 3, and separates a first sub-cavity 1011 and a second sub-cavity 1012 that are open to each other. The water inlet 102 is provided on the bottom wall of the first sub-cavity 1011, and the buoyancy level switch 3 is provided in the second sub-cavity 1012.

[0037] When the first water tank 1 is filled with water, the water flow will affect the buoyancy liquid level switch 3, resulting in inaccurate detection or false triggering of the buoyancy liquid level switch 3. Therefore, the baffle 14 is used to isolate the second sub-cavity 1012 to shield the buoyancy liquid level switch 3 to prevent excessive water flow disturbance, resulting in inaccurate detection of the buoyancy liquid level switch 3. The first sub-cavity 1011 and the second sub-cavity 1012 are designed to be open, which can prevent the interference of water flow on the buoyancy liquid level switch 3 and can detect the liquid level immediately.

[0038] like Figure 5 As shown, a second water outlet 103 connecting the first sub-cavity 1011 and the second sub-cavity 1012 is provided at the bottom of the baffle 14. The second water outlet 103 can disturb the water flow of the second sub-cavity 1012 to prevent impurities from settling in the second sub-cavity 1012, and can also improve the synchronization of water inlet between the second sub-cavity 1012 and the first sub-cavity 1011.

[0039] In an exemplary embodiment, Figure 3-Figure 6 As shown, the buoyancy liquid level switch 3 is an electronic liquid level switch, including a main body 30 extending to the bottom of the water storage cavity 11 of the first water tank 1, and a first floating member 31 disposed on the main body 30 and capable of floating up and down on the main body 30.

[0040] The first floating member 31 in this embodiment adopts a floating ring, which is sleeved on the outer wall of the main body 30 and can move up and down on the main body 30 according to the change of water level, and the first floating member 31 can float with the change of water level in the first water tank 1 to trigger the control signal, and the control signal is used to control the working state of the water inlet valve 5. For example, when the first floating member 31 triggers to reach the upper liquid level signal, the first water tank 1 is filled with water, and the water inlet valve 5 is controlled to be closed; when the first floating member 31 triggers to reach the lower liquid level signal, the first water tank 1 needs to be replenished, and the water inlet valve 5 is controlled to be opened.

[0041] In another exemplary embodiment, Figure 7-Figure 9 As shown, the buoyancy liquid level switch 3 is a mechanical liquid level switch, including a first floating member 31 that can float following the change of the water level of the first water tank 1, and a blocking member 32 that is connected to the first floating member 31 and moves following the first floating member 31 to block or open the water outlet port 33 of the water inlet valve 5. In this embodiment, the water inlet valve 5 is arranged in the first water tank 1, and the first floating member 31 is movably installed with the water inlet valve 5 and can float up and down following the water flow.

[0042] When the first floating member 31 floats to a certain position, the blocking member 32 blocks the water outlet port 33, the water replenishment of the first water tank 1 is completed, and the water inlet valve 5 is closed; when the first floating member 31 descends to a certain position, the blocking member 32 opens the water outlet port 33, the first water tank 1 needs to be completed, and the water inlet valve 5 is opened.

[0043] like Figure 3 As shown, the first water tank 1 of this embodiment includes a tank body 1a and a cover body 1b that is matched with the tank body 1a. By setting the first water tank 1 as a split type, it is convenient to install components such as the functional water generating device 2 and the buoyancy liquid level switch 3, and by setting the cover body 1b, dust and the like can be prevented from falling into the tank body, so that the water tank is kept clean.

[0044] The buoyancy level switch 3 is provided on the cover 1b and extends into the box body 1a. The cover 1b is provided with a port (not shown) corresponding to the agent addition port of the functional water generating device 2, and a cover 10b that cooperates with the port to cover the port, so as to facilitate the addition of antiscalant.

[0045] like Fig.10As shown, the embodiment of the present application provides a toilet 200, which can be a sitting or squatting toilet. The toilet 200 includes a toilet body and a water tank assembly 100 installed on the toilet body, and the water tank assembly 100 can supply water to the toilet 200.

[0046] The water tank assembly 100 includes the first water tank 1, the second water tank 2 and the water inlet linkage assembly 4 as described in any of the above embodiments. The first water tank 1 is provided with an overflow port 104 (see Figure 2 ), so that the water in the first water tank 1 can overflow into the second water tank 2 from the overflow port 104.

[0047] The second water tank 2 of the water tank assembly 100 of the embodiment of the present application takes in water through the overflow of the first water tank 1, thereby avoiding the installation of too many water valves, reducing the complexity of connection and control, and saving space.

[0048] In addition, the water tank assembly 100 of the embodiment of the present application is capable of providing feedback and controlling the water level inflow of the second water tank 2 by setting a water inlet linkage assembly 4 that cooperates with the buoyancy liquid level switch 3 on the second water tank 2, so that the floating water inlet valve 3 indirectly controls the water inflow of the second water tank 2, thereby realizing the control of the water inflow and water level of the first water tank 1 and the second water tank 2, thereby realizing continuous water use of the two water tanks, reducing the use of components such as liquid level sensors and control valves, saving costs, and ensuring reliable control.

[0049] The water inlet linkage assembly 4 of the embodiment of the present application is disposed at the second water tank 2, and is configured to float following the water level change of the second water tank 2. When the buoyancy liquid level switch 3 adopts an electronic liquid level switch, the water inlet linkage assembly 4 can cooperate with the first floating member 31 to enable the first floating member 31 to trigger a control signal. The water inlet linkage assembly 4 includes a first working state in which the first floating member 31 cooperates with the first floating member 31 to enable the first floating member 31 to trigger a control signal, and a second working state in which the first floating member 31 is released.

[0050] When the buoyancy liquid level switch 3 adopts a mechanical liquid level switch, the water inlet linkage assembly 4 includes a first working state of cooperating with the first floating member 31 to drive the blocking member 32 to open the water outlet port 33 of the water inlet valve 5 and a second working state of closing the water outlet port 33 of the water inlet valve 5.

[0051] In the embodiment of the present application, the water inlet linkage assembly 4 switches between the first working state and the second working state under the interaction of its own gravity and the water level change of the second water tank 2. Alternatively, the water tank assembly 100 further includes a reset element (not shown) that provides a reset force for the water inlet linkage assembly 4, and the water inlet linkage assembly 4 switches between the first working state and the second working state under the interaction of the reset element and the water level change of the second water tank 2.

[0052] like Fig.11As 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 of 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 the first floating member 31 to drive the buoyant water inlet valve 5 to open and replenish water; in the second working state, the connecting rod 42 releases the first floating member 31 and does not generate force on the buoyant water inlet valve 5.

[0053] In this embodiment, the second floating member 41 is provided with a mounting groove (not shown), and the connecting rod 42 is inserted into the mounting groove and installed in cooperation with the second floating member 41; or, the second floating member 41 and the connecting rod 42 are connected by connecting members such as screws. Of course, the second floating member 41 and the connecting rod 42 can also be formed in one piece, which is not limited here. The second floating member 41 in this embodiment adopts a buoy, and of course it can also be a floating ball, etc., which is not limited here.

[0054] When the water level drops, the water inlet linkage assembly 4 drops under the action of its own gravity, so that the water inlet linkage assembly 4 drives the first floating member 31 to open the water inlet valve 5 and replenish water into the second water tank 2. When the water level of the first water tank 1 rises, the water inlet linkage assembly 4 is pushed up, and the water inlet linkage assembly 4 releases the force on the first floating member 31. At this time, the second water tank 2 is in a full load state, and the water inlet valve 5 can be in a closed state or in an open state to replenish water into the first water tank 1. The water inlet linkage assembly 4 does not interfere with the operation of the buoyancy liquid level switch 2.

[0055] In this embodiment, the position of the first floating member 31 is controlled by the linkage between the water inlet linkage assembly 4 and the first floating member 31, thereby controlling the working state of the water inlet valve 5 and maintaining continuous water use in the two water tanks.

[0056] like Figure 2 As shown, the first water tank 1 of this embodiment is suspended on the second water tank 2 and is located outside the second water tank 2. The first water tank 1 is provided with a hanging groove 105, which is inserted into the side wall of the second water tank 2 from the notch of the second water tank 2 to hang the first water tank 1.

[0057] like Figure 2 As shown, the first water tank 1 is provided with a guide channel 106 extending into the inner cavity of the second water tank 2 and guiding the water flow along the side wall of the first water tank 1 into the first water tank 1, and the water inlet end of the guide channel 106 is connected with the overflow port 104. The water flow entering the first water tank 1 is guided to the side wall of the second water tank 2 through the guide channel 106, which can prevent water splashing on the one hand and reduce water inlet noise on the other hand.

[0058] like Fig.10As shown, the water tank assembly 100 of the embodiment of the present application further includes a controller 8 connected to the buoyancy level switch 3 and the water inlet valve 5. The controller 8 is configured to perform the following operations when receiving a water use command of the first water tank 1:

[0059] S1. When the water level in the first water tank 1 drops, driving the first float 31 to drop and triggering a control signal below the first liquid level, and when the first float 31 continues to drop and triggers a control signal to reach the second liquid level or when the control signal to reach the second liquid level reaches a predetermined time, the controller 8 controls the water inlet valve 5 to open to replenish water in the first water tank 1.

[0060] S2. When the water level of the first water tank 1 rises, driving the first float 31 to rise and triggering a control signal to reach the first liquid level, the controller 8 controls the water inlet valve 5 to close. At this time, the replenishment of the first water tank 1 is completed.

[0061] The water tank assembly 100 of the embodiment of the present application sets the relationship between the first liquid level and the second liquid level or time, so that when the water level of the first water tank 1 is too low after use, it is necessary to control the water inlet valve 5 to let water in.

[0062] The controller 8 of the embodiment of the present application is also configured to perform the following operations when receiving a water use command from the second water tank 2: S3, when the water level of the second water tank 2 drops, driving the water inlet linkage assembly 4 down, the first floating member 31 acts and triggers the control signal below the first liquid level, the controller 8 controls the water inlet valve 5 to open; S4. When the water level of the second water tank 2 rises, the water inlet linkage assembly 4 rises to release the action on the first floating member 31. When the water level of the first water tank 1 rises, the first floating member 31 rises and triggers a control signal to reach the first liquid level, the controller 8 controls the water inlet valve 5 to close.

[0063] Among them, whether the first water tank 1 and the second water tank 2 use water can be determined by a water use command triggered by the user. The water use command can be a physical switch or a voice-controlled switch.

[0064] When the water tank assembly 100 of the embodiment of the present application is working, in the initial state, there is no water in the first water tank 1 and the second water tank 2, the buoyancy liquid level switch 3 is at a low position under the gravity of the first floating member 31, and the controller 8 controls the water inlet valve 5 to open to replenish water in the first water tank 1. Since there is no water in the second water tank 2, the water inlet linkage assembly 4 presses against the first floating member 31 under the action of its own gravity, even if the water level of the first water tank 1 is full of water, since the first floating member 31 cannot rise under the drive of the water flow, the controller 8 cannot receive the control signal to reach the first liquid level, and the water inlet valve 5 is kept to replenish water until the second water tank 2 is filled with water.

[0065] When the water in the first water tank 1 reaches the overflow level, the water flows from the overflow port 104 into the first water tank 1 to replenish the second water tank 2. When the water level in the second water tank 2 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 buoyancy of the water flow in the first water tank 1, and no force is applied to the first floating member 31. Then, the first floating member 31 rises to the first liquid level under the buoyancy of the water flow in the first water tank 1, and the controller 8 receives the control signal of reaching the first liquid level, and then closes the water inlet valve 5, thereby stopping the replenishment of the entire water tank assembly 100.

[0066] When the second water tank 2 is used, the water level of the second water tank 2 drops. At this time, regardless of whether the water in the first water tank 1 is used, the water inlet linkage assembly 4 presses the first floating member 31 under its own weight, triggering a signal of a level lower than the first liquid level, so that the water inlet valve 8 opens to replenish water for the second water tank 2. Similarly, when the water inlet valve 8 is completed, the water inlet valve 8 is closed.

[0067] When the first water tank 1 uses water, the water level of the first water tank 1 drops. When the water level drops less (lower than the first liquid level and greater than the second liquid level), no water replenishment is performed. When the water level drops to a low water level (second liquid level position) or is lower than the second liquid level position for a predetermined time (which may be 5-10 seconds), a water replenishment control signal is triggered, and the controller 8 controls the water inlet valve 5 to open for water replenishment. When the water level continues to be lower than the second liquid level after the water inlet valve 5 is opened for water replenishment, it is necessary to stop using water in the first water tank 1 to prevent the first water tank 1 from drying out due to lack of water, which may cause damage to the device.

[0068] The water tank assembly 100 of the embodiment of the present application utilizes the water level change of the water tank and the water inlet linkage assembly 4 to control the first floating member 31 of the buoyancy liquid level switch 3 to achieve the function of replenishing water for the two water tanks. It does not require the use of an electromagnetic valve body or a motor, and has simple connection and low cost.

[0069] The design of the water inlet linkage assembly 4 of the embodiment of the present application can not only realize the simultaneous replenishment of water to the two water tanks, but also realize the independent replenishment of water to the two water tanks, and can repeat the action of continuous replenishment. When the mechanical floating liquid level switch 3 is used, the control principle is similar to the electronic control principle, which will not be repeated here.

[0070] like Fig.10 As shown, the toilet 200 also includes a flushing system installed in cooperation with the water tank assembly 100 , and the flushing system includes a human body cleaning system A connected to the first water tank 1 and a toilet flushing system B connected to the second water tank 2 .

[0071] Among them, the clean water circuit A includes a first boosting device 61, a heating device 62, and a cleaning device 63. The first boosting device 61 boosts the water in the first water tank 1 and then transports it to the cleaning device 63 for cleaning the human body. The heating device 62 is used to heat the water in the first water tank 1 and then supply it to the cleaning device 63.

[0072] The controller 8 is also connected to the cleaning system A. When the controller 8 receives a water use command from the first water tank 1, it performs the following operations: When the water level of the first water tank 1 drops, so that the first floating member 31 triggers a control signal lower than the second liquid level or when the control signal lower than the second liquid level reaches a predetermined time, the controller 8 controls the human body washing system A to stop running. The water level at this time indicates that the replenishment amount is insufficient. Stopping the use of the first water tank 1 can avoid a poor user experience, and more importantly, prevent dry burning caused by lack of water.

[0073] The toilet flushing system B includes a second booster device 71, a water channel distribution valve 72, a siphon nozzle 73 and a brush ring nozzle 74. The second booster device 72 increases the water output from the first water tank 2 and supplies it to the water channel distribution valve 72 to divide the water into two paths and supply them to the siphon nozzle 73 and the brush ring nozzle 74 respectively to flush the toilet body.

[0074] The two water tanks of the flushing assembly 100 of the embodiment of the present application can respectively supply water to the human body cleaning system A and the toilet flushing system B of the flushing system, and can match the water replenishment of the two flushing systems, reducing functional components and reducing the complexity of the connection. The water tank assembly 100 can maintain the water of the flushing working mode of the two continuous waterways of the toilet 200.

[0075] The toilet 200 of the embodiment of the present application can reduce the complexity of the system and greatly improve the environmental adaptability and production convenience by optimizing the water system.
