[0002] The smart toilet water tank components currently on the market include three components: an inlet valve, a water pump, and a water diverter valve to realize the two processes of water tank replenishment and water tank flushing. The existing smart toilet water tank components replenish water into the water tank through the inlet valve, and the water tank outlet is connected to the water pump through a special-shaped rubber tube. The water pump is then connected to the stepper motor water diverter valve through a special-shaped rubber tube. The signal is transmitted to the water diverter valve through the mainboard, controlling the stepper motor to rotate the corresponding number of steps, driving the water diverter valve paddle to rotate, thereby realizing the function of switching water.

[0003] However, during use, the existing smart toilet tank assembly is too large because the water inlet valve, water pump, and water diversion valve are independently connected. At the same time, because each component is independent, the connection part uses customized rubber tubes and fixed clips for manual assembly, which makes the cost too high. In addition, the control logic of the existing motor-controlled water diversion valve is relatively complex, and a large amount of waterproof glue needs to be applied to the motor seal to ensure reliability. At the same time, there is leakage in the water diversion process of the switching scheme, which reduces the flushing force. Summary of the invention

[0004] The purpose of the present invention is to provide a smart toilet mechanical water inlet and water diversion integrated valve, the water diversion valve is controlled by a float instead of a motor, a motor is omitted, and the control logic is relatively simple.

After the flushing is started, the water pump is started, and the water in the water tank is pumped out and sent to the first channel. The water flow in the first channel impacts the switching valve, causing the valve core of the switching valve to move downward. The third channel and the second channel are connected, and the water flows into the second channel. At this time, the water diversion float is at a high position due to buoyancy, and the water diversion valve switches to the upper nozzle to discharge water. The water level in the water tank drops, and when it drops below the water diversion buoy, the water level in the water diversion buoy also drops, driving the water diversion float to drop. At the same time, the discharge valve is closed to seal the water diversion buoy, and the water diversion valve switches to the lower nozzle to discharge water. When the lower nozzle discharges water, the water flow is guided to the diversion port through the pipeline at the same time, and the water diversion buoy is replenished with water through the diversion port. That is, after the lower nozzle discharges water for a certain period of time, the water diversion float will also float up, and the switching valve automatically switches to the upper spray state to complete the third stage of water replenishment. The entire set of upper spray, lower spray and upper spray water replenishment actions are completed, which is completely completed by the mechanical structure. Compared with the original mechanism, there is one less water diversion motor, and the control logic is greatly simplified.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] See also Figure 1-8 As shown, the present invention is a smart toilet mechanical water inlet and water distribution integrated valve, including a main body 1, a water pump 2, a water inlet mechanism 3 and a water distribution mechanism 4.

[0024] The main body 1 has a first channel 11, a second channel 12 and a third channel 13, and the upper part of the main body has a switching valve 5. When the valve core of the switching valve rises, the first channel and the third channel are connected, and when the valve core of the switching valve descends, the first channel and the second channel are connected. In this embodiment, the switching valve 5 includes a valve cover 51 and a valve core 52. The valve cover 51 has a water channel 511. One end of the water channel 511 is connected to the second channel 12. The other end of the waterway 511 is a sleeve 512, and the sleeve 512 is opposite to the top of the third channel 13. The valve core 52 includes a blocking block 521 and a guide block 522 arranged at the upper end of the blocking block 521. The gap between the guide blocks 522 is for water to pass through. The guide block 522 is inserted into the sleeve 512. When tap water is supplied, the blocking block seals the sleeve upwards, allowing the first channel and the third channel to communicate. After the water flows in from the tap water pipe, it flows out from the water pump and enters the water tank. When the water pump supplies water, the blocking block seals the top of the third channel downwards, and the water from the water pump enters the second channel and passes through the water diversion valve, and then is ejected from the upper nozzle and the lower nozzle.

[0025] The water inlet mechanism 3 includes a water inlet valve 32. The bottom of the first channel 11 is connected to the water pump 2. The third channel 13 is provided with a water inlet 31. The water inlet 31 is provided with a water inlet valve 32. The valve stem 321 of the water inlet valve cooperates with the top rod of the water inlet float 33. When the water inlet float 33 floats up, the water inlet valve 32 is closed. The water inlet float 33 is arranged in the water inlet buoy 34. The bottom of the water inlet buoy 34 is provided with a delayed water replenishment hole 341. The water diversion mechanism 4 includes a water diversion valve 41, a water inlet of the water diversion valve is connected to the second channel, the water diversion valve has two water outlets 42, 43, one water outlet 42 is connected to the upper nozzle 44, the upper nozzle 44 has a diversion port 441, the diversion port 441 is connected to the lower nozzle through a pipeline 442, and the other water outlet 43 is connected to the lower nozzle 45. The valve stem of the water diversion valve 41 matches the top rod of the water diversion float 46. When the water diversion float floats up, the water diversion valve switches to the upper nozzle to discharge water. When the water diversion float sinks, the water diversion valve switches to the lower nozzle to discharge water. The water diversion float 46 is arranged in the water diversion buoy 47. A discharge valve 48 is arranged at the bottom of the water diversion buoy 47. The diversion port 441 sprays water toward the water diversion buoy 47.

[0026] In this embodiment, the specific structure of the water diversion valve switching the upper spray and the lower spray is that the water diversion valve includes two control chambers 411, a water inlet chamber 412 and a water diversion valve stem 413, each of the control chambers is provided with a valve plate 414, and the valve plate separates the water inlet chamber and the water outlet under the action of a spring 415. The control chamber 411 has a control flow channel 416, and the outlet of the control flow channel 416 is connected to the water tank. The water diversion valve stem 413 is rotatably connected to the outer wall of the water diversion valve 41, and the first block 4a and the second block 4b are respectively provided on both sides of the rotation connection of the water diversion valve stem. One end of the water diversion valve stem is connected to the top rod of the water diversion float. When the water diversion float rises, the first block is connected to the outlet of one of the control flow channels, and when the water diversion float falls, the second block is connected to the outlet of another control flow channel.

[0027] The discharge valve 48 includes a main body 481 and a floating cover 482. A through hole 471 is provided at the bottom of the water diversion float. The upper end of the main body penetrates into the through hole. There is a gap between the main body and the through hole. The floating cover is provided at the lower end of the main body.

[0028] Working condition 1: The water tank is full and the flushing is not started. Due to the buoyancy of the water, the water distributing float floats up, driving the water inlet connecting rod upward, closing the pressure relief port of the water inlet valve, making the water inlet pressure less than the pressure in the pressure chamber, and pushing the sealing diaphragm to seal the water inlet. At the same time, the water distributing float and the floating cover of the discharge valve float up, so that the water distributing valve switches to the upper nozzle to discharge water, and the water in the water tank is connected to the water in the buoy.

[0029] Working condition 2: The water tank is full of water, flushing is started, the water pump is started, the water in the water tank is pumped out and sent to the first channel. The water flow in the first channel impacts the switching valve, causing the valve core of the switching valve to move downward. The third channel and the second channel are connected, and the water flows into the second channel. At this time, the water diversion float is at a high position due to buoyancy, the water diversion valve switches to the upper nozzle to discharge water, and the water level in the water tank drops until the water level in the water tank falls below the water inlet buoy. Since there is a delayed water replenishment hole in the water inlet buoy at the water inlet end, the water inlet float cover will not fall immediately. As the water level in the water tank is lower than the water inlet buoy, the delayed water replenishment hole begins to drain water outward. After the whole flushing process is completed, the water inlet float falls and the water inlet valve is opened. At the same time, the water level continues to drop. When it drops below the water diversion buoy, the water level in the water diversion buoy also drops, driving the water diversion float to drop, so that the water diversion valve switches to the lower nozzle to discharge water. When the lower nozzle discharges water, the water flow is simultaneously guided to the diversion port through the pipeline, and the water diversion buoy is replenished with water through the diversion port. That is, after the lower nozzle has discharged water for a certain period of time, the water diversion float will also float up, and the switching valve will automatically switch to the upper spray state, completing the third stage of water replenishment.

[0030] Working condition 3, the water tank is short of water, and the flushing is not started; with the completion of the upper spray water replenishment action, the flushing step is completed. At this time, the delayed water replenishment hole on the water inlet float drains the water in the water inlet float, and the water inlet float falls, driving the valve stem of the water inlet valve to fall, and the pressure relief port of the water inlet valve makes the water inlet pressure greater than the pressure in the pressure chamber, pushing the sealing diaphragm backward to open the water inlet, and the tap water enters the third channel from the water inlet. Under the impact of the water flow. The water level of the water tank gradually rises with continuous water replenishment until it submerges the water distribution float. The water relief valve reopens due to the buoyancy, waiting for the next round of flushing to repeat the above working logic.
