The cleaning water path requires higher water quality, and the flush water path has the possibility of backflow when negative pressure appears in the pipeline, therefore, in order to prevent the cleaning water path from being polluted by the flush water path, the flush water path and the cleaning water path are required to be independent. Usually, the flush water path is supplied by flush water tank, and the flush water tank is installed on the ceramic body of the intelligent closestool, while the cleaning water path is supplied by cleaning water tank, and the cleaning water tank is installed on the cover plate of the intelligent closestool. Of course, there is also a way of connecting the cleaning water tank directly with the external water path through electromagnetic valve switch, but each has advantages and disadvantages, and consumers can choose by themselves. For the way of supplying the cleaning water path by the cleaning water tank, since the cleaning water tank and components such as valve switch and water pump need to occupy a large installation space, it leads to the large volume of the rear shell of the intelligent closestool cover plate, which cannot be made into ultra-thin and mini type intelligent closestool cover plate, affecting the competitiveness of the product.

[0019] 4. When the water inlet solenoid valve fails to stop water normally, it will cause the liquid level in the flushing water tank to rise, and eventually flow out from the overflow hole. Similarly, if the water in the ceramic body basin flows back to the flushing water tank, the water in the flushing water tank will also eventually flow out from the overflow hole, preventing the liquid level in the flushing water tank from continuously rising and mixing with the cleaning water tank.

[0028] Please refer to Figures 1 to 6The utility model provides a kind of intelligent closestool composite water storage tank 100, including flushing water tank 120, cleaning water tank 140, water inlet solenoid valve 160, water level detection module 180 and control system (figure is not shown), the flushing water tank 120 is connected ceramic body toilet 200 by flushing waterway 110, the cleaning water tank 140 is connected intelligent cover plate cleaning assembly 300 (human cleaning device) by cleaning waterway 130.The water inlet solenoid valve 160 is opened to be used to the water supplement of the cleaning water tank 140, that is, water outlet of water inlet solenoid valve directly enters cleaning water tank 140.The control system is according to the signal sent by the water level detection module 180 received and controls the water inlet solenoid valve 160 to open or close.The lower part of the cleaning water tank 140 is provided with gas storage cavity 142, therefore, cleaning water tank 140 not only has the function of water storage, but also can float on water surface.The cleaning water tank 140 is floatingly arranged in the flushing water tank 160, and floating means that it can float up and sink, and it can also be understood as rising and moving down.

[0029] When the water inlet solenoid valve 160 is opened to supplement water, water enters the cleaning water tank 140, and the water in the cleaning water tank 140 flows into the flushing water tank 120 after overflowing. The water level detection module 180 is used to detect the height of the liquid surface in the cleaning water tank 140 in the flushing water tank 120 and form a signal to the control system, that is, the water level detection module detects the actual height of the liquid surface in the cleaning water tank, or the height from the ground, not the height in the cleaning water tank. When the water level detection module 180 detects that the height of the liquid surface in the cleaning water tank 140 is lower than the set lower limit water level, it sends an opening signal to the control system, so that the control system opens the water inlet solenoid valve 160. When the water level detection module 180 detects that the height of the liquid surface in the cleaning water tank 140 is higher than the set upper limit water level, it sends a closing signal to the control system, so that the water inlet solenoid valve 160 is closed.

[0030] The upper limit water level is higher than the full water level of the cleaning water tank 140, and the liquid surface in the flushing water tank 120 rises to a height that can support the cleaning water tank to float, that is, when the cleaning water tank is full, water overflows into the flushing water tank, and as the height of the liquid surface in the flushing water tank rises, the cleaning water tank first floats on the liquid surface in the flushing water tank, and then rises with the height of the liquid surface in the flushing water tank. Since the cleaning water tank is rising, the actual height of the liquid surface in the cleaning water tank is also rising, and when the actual height of the liquid surface in the cleaning water tank rises to the height of the upper limit water level, the water inlet solenoid valve is closed.

[0031] The composite water storage tank of the utility model, although the cleaning water tank 140 is built-in in the flushing water tank 120, but the cleaning water tank 140 can float in the flushing water tank 120, to ensure that the cleaning waterway 130 is relatively independent.

[0032] Preferably, a vertical limiting column 122 is arranged in the flushing water tank 120, and the cleaning water tank 140 is movably sleeved on the limiting column 122. Thus, the flushing water tank is lifted along the limiting column, and the stability is good.

[0033] Preferably, the limiting column 122 is provided with an upper baffle 124. During daily use, when only the cleaning water tank 140 is drained, at the initial stage of the drainage, the cleaning water tank 140 further floats up and leans against the upper baffle 124 due to the gravity reduction, and the liquid level in the cleaning water tank is still higher than the set upper limit water level, and the water inlet electromagnetic valve 160 remains in the closed state. When the liquid level in the cleaning water tank 140 drops to the lower limit water level with the continuous use of water, the water inlet electromagnetic valve is switched to the open state. The upper baffle can avoid the cleaning water tank from floating up for a long distance, and is beneficial to reducing the height of the flushing water tank.

[0034] Preferably, the limiting column 122 is provided with a lower baffle 126. During daily use, after the flushing water tank 120 is drained, the cleaning water tank 140 falls on the lower baffle 126. In this way, the floating stroke of the cleaning water tank is small, and the stability is better.

[0035] Preferably, the flushing water tank 120 is provided with an overflow hole, the height of the overflow hole is lower than the height of the upper limit water level, and is higher than the liquid level in the cleaning water tank when the liquid level reaches the upper limit water level. Thus, if the water inlet electromagnetic valve 160 fails to stop water, even if the liquid level in the flushing water tank continues to rise, it will eventually flow out from the overflow hole, and will not exceed the height of the upper limit water level, and thus will not enter the cleaning water tank 140.

[0036] Preferably, a cleaning water pump 132 is arranged on the cleaning water path 130, and the cleaning water pump 132 is installed at the rear part of the ceramic body of the closestool, that is, the rear part of the ceramic bowl 200. In addition, the flushing water tank 120 is also installed at the rear part of the ceramic body of the closestool.

[0037] Preferably, the water inlet electromagnetic valve 160 is arranged at the upper part of the flushing water tank 120 and is vertically aligned with the cleaning water tank 140, and the water level detection module 180 is arranged at the upper part of the flushing water tank 120 and is vertically aligned with the cleaning water tank 140.

[0038] Preferably, a fixing plate 128 is arranged in the flushing water tank 120, and the water level detection module 180 is installed on the fixing plate 128.

[0039] Preferably, the water level detection module 180 comprises a guide column 182 and a liquid level float 184, and the liquid level float 184 is movably sleeved on the guide column 182 in the vertical direction.

[0040] Preferably, the upper end of the guide post 182 is provided with an upper stop step 186 corresponding to the liquid level float, and the lower end of the guide post is provided with a lower stop step 188 corresponding to the liquid level float.

[0041] During work:

[0042] Before the first water storage, such as Figure 4 As shown, when neither the cleaning water tank 140 nor the flushing water tank 120 has water, the cleaning water tank 140 rests on the lower baffle 126, and the liquid level float 184 rests on the lower stop step 188. The height of the liquid level float 184 is lower than the lower limit water column, meaning the liquid level in the cleaning water tank 140 is lower than the set lower limit water level. The inlet solenoid valve 160 then opens to allow water to enter. Water flows from top to bottom into the cleaning water tank 140, and the liquid level in the cleaning water tank continuously rises. When the cleaning water tank is full, it overflows and flows downwards into the flushing water tank 120. The liquid level in the flushing water tank then continues to rise. Afterwards, the cleaning water tank 140 floats on the surface of the flushing water tank 120 and rises together with the flushing water tank. In other words, after the cleaning water tank floats on the surface of the flushing water tank, the liquid level in the cleaning water tank rises as the cleaning water tank rises. Finally, when the liquid level in the cleaning water tank 140 rises to the upper limit, that is, when the liquid level float 184 rises to the upper limit, the water inlet solenoid valve 160 closes.

[0043] During normal use, when flushing the water tank at 120 rpm and draining, if... Figure 5 As shown, the water volume in the flushing tank decreases rapidly, and the liquid level in the flushing tank drops rapidly. The liquid level in the cleaning tank 140 drops along with that in the flushing tank 120, thus the liquid level in the cleaning tank 140 also decreases. When the level float 184 drops to the lower limit level as the liquid level in the cleaning tank 140 decreases, the inlet solenoid valve 160 opens to allow water in. However, because the drainage rate of the flushing tank is faster than the inlet rate, the liquid level in the flushing tank 120 continues to drop, and the cleaning tank 140 also continues to drop. Finally, the cleaning tank 140 rests against the lower baffle 126, and the level float 184 lands on the lower stop step 188. When the flushing water tank 120 stops draining, as the liquid level in the flushing water tank rises, the cleaning water tank floats on the surface of the flushing water tank and rises together with the liquid level in the flushing water tank. When the liquid level in the cleaning water tank 140 rises to the upper limit water level, that is, when the liquid level float 184 rises to the upper limit water level, the water inlet solenoid valve 160 closes.

[0044] During daily use, when the washing water tank 140 is draining, at the initial stage of draining, as the water in the washing water tank 140 is drained, the weight of the whole washing water tank is reduced, thus under the action of buoyancy, the washing water tank will further float up with the reduction of its own weight and push against the upper baffle 124. Although the amount of water in the washing water tank 140 is reduced at the initial stage of draining, at the same time, the washing water tank further floats up, thus the liquid level in the washing water tank does not immediately and greatly change, and is still near the upper limit water level, at this time, the water inlet electromagnetic valve 160 still remains in the closed state. Then, as the water in the washing water tank 140 is continuously drained, the liquid level in the washing water tank continuously drops, when the liquid level float 184 drops to the lower limit water level with the liquid level in the washing water tank, the water inlet electromagnetic valve 160 switches to the open state. Then, the washing water tank stops draining, and the liquid level in the washing water tank rises and finally drives the liquid level float 184 to rise to the upper limit water level, and the water inlet electromagnetic valve 160 is closed.

[0045] The above merely describes the preferred embodiments of the present application, and therefore cannot limit the scope of the present application, that is, equivalent changes and modifications made according to the scope of the present application and the content of the specification should still be within the scope of the present application.
