[0028] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that the directional terms such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and are not specific limitations of the present invention.

[0029] like Figures 1 to 6 As shown, Figures 1 to 6 The schematic diagram of the structure of the first embodiment of the automatic flushing mechanism of a toilet of the present invention is shown, which includes a water inlet assembly 1 and a flushing mechanism 2 arranged in the toilet water tank 5, wherein the water inlet assembly 1 includes a water inlet valve seat 11, one end of which is connected to the water inlet pipe 3 to allow water inlet flow. A water inlet cavity 12 connected to the water inlet pipe 3 is arranged in the water inlet valve seat 11, and a drain pipe 13 and a water outlet pipe 14 are arranged on the water inlet valve seat 11, wherein the water inlet cavity 12 is connected to the drain pipe 13 and the water outlet pipe 14 respectively, and the drain pipe 13 is used to discharge water flow into the inner cavity of the toilet water tank 5 to realize the water storage or water replenishment function of the toilet water tank 5. The flushing mechanism 2 includes a flushing pipe seat 21, one end of which is provided with a flushing drive assembly 22, and the other end of the flushing pipe seat 21 is connected to the water outlet pipe 14 through a pipeline, so that water flows into the flushing pipe seat 21 through the water outlet pipe 14, and the flushing drive assembly 22 can drive the flushing valve 7 to open under the impetus of the inlet water flow; a control box 4 is provided at one end of the water inlet valve seat 11, and the control box 4 includes a wireless control module 41 and a water circuit switch device 42, and the two ends of the water circuit switch device 42 are respectively connected to the water outlet pipe 14 and the water inlet chamber 12; the wireless control module 41 is electrically connected to an external wireless device and the water circuit switch device 42, respectively, and is used to control the on-off state between the water outlet pipe 14 and the water inlet chamber 12 through the water circuit switch device 42, so as to control the water inlet and non-water inlet state of the flushing pipe seat 21, thereby controlling the opening or closing state of the flushing valve 7 through the flushing drive assembly 22.

[0030] The present invention constructs a flushing drive waterway connected to the flushing pipe seat 21 between the water inlet valve seat 11 and the control box 4, and provides a moving water flow driving force for the flushing drive assembly 22 in the flushing pipe seat 21 through the flushing drive waterway, so as to push the flushing drive assembly 22 to move and press the flushing valve 7, so that the flushing valve 7 is opened to realize the flushing operation. The wireless control module 41 can control the operation of the waterway switch device 42 according to the received control signal, so that the waterway switch device 42 controls the on-off state of the flushing drive waterway, thereby controlling the flushing valve 7 to open or close, and realizing the automatic flushing operation. The present invention adopts the above-mentioned mechanical flushing drive mode to greatly reduce the cost of the flushing structure, and the flushing power can be greatly improved by using the water flow water pressure as the flushing driving force (the national water pressure standard is: 0.2Kpa-0.6Kpa), ensuring a good flushing effect, and effectively eliminating the hidden danger of water seepage of the flushing mechanism 2, reducing the difficulty of production and manufacturing and the production and maintenance costs.

[0031] Preferably, the wireless control module 41 includes a main control board, an MCU controller and a wireless communication module arranged on the main control board. The external wireless device includes a wireless remote controller and a mobile terminal.

[0032] In order to realize automatic flushing, Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, push rods 61 are respectively provided on both sides of the bottom of the flush button 6 of the toilet water tank 5. The push rods 61 on both sides of the flush button 6 are in contact with the flush valve 7. The flush button 6 presses the flush valve 7 through the push rods 61 to achieve flushing. A fixed installation component 23 is provided on the outside of the flush pipe seat 21. All fixed installation components 23 are installed on the push rods 61 on one side of the flush button 6. The flush button 6 is movably connected to the toilet water tank 5; the driving end of the flush drive component 22 is movably in contact with the bottom edge of one side of the flush button 6. When the flush pipe seat 21 is filled with water, the inflow water flow will push the flush drive component 22 to move, so that the driving end of the flush drive component 22 lifts the bottom edge of one side of the flush button 6, so that the flush button 6 flips to the other side. At this time, the push rod 61 on the other side of the flush button 6 will press the flush valve 7 downward to open the flush valve 7 to achieve automatic flushing.

[0033] The fixed installation assembly 23 includes a clamping portion 231 and a locking member 232 . The clamping portion 231 includes two clamping plates 233 . The two clamping plates 233 are locked and fixed on the corresponding push rods 61 through the locking member 232 to achieve relative fixed installation of the flushing pipe seat 21 and the flushing mechanism 2 .

[0034] Specifically, Figure 2 , Figure 5 and Figure 6 As shown, a propulsion chamber 24 is provided at one end of the flushing pipe seat 21, and a water inlet pipe port 25 connected to the propulsion chamber 24 is provided at the other end of the flushing pipe seat 21, and the water inlet pipe port 25 is connected to the water outlet pipe through a pipeline; the flushing drive assembly 22 is provided in the propulsion chamber 24, and a driving hole 26 is provided at one end of the propulsion chamber 24, and a drainage hole 27 is provided between the propulsion chamber 24 and the water inlet pipe port 25, and the drainage hole 27 discharges water into the inner cavity of the toilet tank 5 to discharge the inlet water flow. The flushing drive assembly 22 can move in the propulsion chamber 24, and the driving end of the flushing drive assembly 22 can pass through the driving hole 26 and movably abut against the bottom edge of one side of the flushing button 6. When water flows into the water inlet 25 of the flush pipe seat 21, the water flows into the propulsion chamber 24 to push the flush drive assembly 22 to move in the propulsion chamber 24, so that the driving end of the flush drive assembly 22 lifts the flush button 6 and presses the flush valve to realize automatic flushing; when the water stops flowing, the flush drive assembly 22 is reset, the flush valve is closed, and the flushing stops. Among them, the diameter of the drainage hole 27 is much smaller than the diameter of the water inlet 25 to ensure that when water flows in, there is enough water pressure to push the flush drive assembly 22 to move, thereby ensuring the stable implementation of the automatic flushing work.

[0035] In order to improve the automatic flushing effect, such as Figures 5 to 6 As shown, the flush drive assembly 22 includes a push rod 221 and a spring member 222. The push rod 221 includes a push head 223 and a push rod portion 224. The push head 223 can move in the push chamber 24. A sealing ring is sleeved on the outer wall of the push head 223. The push head 223 is sealed and connected to the inner wall of the flush pipe seat 21 through the sealing ring. One end of the push rod portion 224 is inserted into the drive hole 26, and the other end of the push rod portion 224 is arranged on the push head 223; the spring member 222 is nested on the push rod portion 224, and the two ends of the spring member 222 are respectively abutted against the push head 223 and the inner wall of the flush pipe seat 21. When water enters, when the water flows into the propulsion chamber 24, the water will contact the propulsion head 223 and push the propulsion head 223 to overcome the elastic force of the spring member 222 and move toward the flush button direction, so that the push rod portion 224 on the propulsion head 223 passes through the drive hole 26 and lifts the flush button, and the automatic flushing operation is realized by pressing the flushing valve; when the water stops entering, under the gradually decreasing water pressure and the resetting force of the spring member 222, the propulsion head 223 will accelerate the resetting operation to accelerate the closing operation of the flushing valve, thereby accelerating the stopping of the flushing operation, and then controlling the flushing volume within the optimal range, avoiding excessive flushing time and excessive flushing volume, and effectively improving the automatic flushing effect.

[0036] Preferably, a water inlet groove 225 is provided in the propulsion rod 221, and the water inlet groove 225 is connected to the water inlet pipe port 25; when the incoming water flows into the propulsion chamber 24, the water will flow into the water inlet groove 225 to increase the contact area between the propulsion rod 221 and the water flow, thereby increasing the driving force for pushing the propulsion rod 221, so that the propulsion rod 221 can accelerate the automatic flushing work and improve the automatic flushing effect.

[0037] In order to control the water inlet state of the flushing pipe seat 21, Figures 3 to 4 As shown, the control box 4 is provided with a first connecting hole 43 and a second connecting hole 44 at one end close to the water inlet chamber 12, wherein the first connecting hole 43 is connected to the water inlet chamber 12, and the second connecting hole 44 is connected to the water outlet pipe 14; the first valve pipe 421 of the water circuit switch device 42 is connected to the first connecting hole 43, and the second valve pipe 422 of the water circuit switch device 42 is connected to the second connecting hole 44, and the water circuit switch device 42 is a flushing solenoid valve. The on-off state of the first valve pipe 421 and the second valve pipe 422 is controlled by the water circuit switch device 42 to control the on-off state between the water outlet pipe 14 and the water inlet chamber 12, thereby controlling the water inlet state of the flushing pipe seat 21, and realizing the automatic flushing work of the flushing mechanism 2.

[0038] In order to improve the battery life of the product and reduce the frequency of battery replacement, such as Figure 3 As shown, a mounting seat 131 is provided on the drain pipe 13, the inner cavity of the mounting seat 131 is communicated with the inner cavity of the drain pipe 13, and a hydroelectric generator 132 is installed on the mounting seat 131; a battery module 45 is provided in the control box 4, and the wireless main control module is electrically connected to the power generation end of the hydroelectric generator and the battery module 45 respectively. When the water in the water inlet cavity 12 is discharged from the drain pipe 13 to the inner cavity of the toilet water cavity, the water flow will pass through the hydroelectric generator 132, so that the hydroelectric generator 132 generates electricity, and the electricity generated by the hydroelectric generator 132 will power the wireless main control module and the battery module 45, so as to improve the endurance of the battery module 45, and there is no need to frequently replace the power supply battery, so that the product is highly efficient, energy-saving and environmentally friendly.

[0039] In order to realize the automatic water inlet or water replenishment function, such as Figure 3 , Figure 7 and Figure 8As shown, the water inlet valve seat 11 is provided with a base 111 and a pressure relief valve cover 112 installed on the base 111, a water pipe 113 is provided in the base 111, a water inlet pipe sleeve 114 is provided at the lower part of the base 111, the water inlet pipe 3 is embedded in the water inlet pipe sleeve 114, the water inlet pipe port of the water pipe 113 is connected to the water outlet end of the water inlet pipe 3; the pressure relief valve cover 112 is provided with a pressure relief hole 115, the pressure relief valve cover 11 A water-stop gasket 116 is provided on the inner side of the pressure relief valve cover 112, the inner cavity enclosed by the pressure relief valve cover 112 and the water-stop gasket 116 is communicated with the pressure relief hole 115, the water inlet cavity 12 is enclosed between the water-stop gasket 116 and the base 111, the water inlet cavity 12 is communicated with the water outlet of the water pipe 113, and the water-stop gasket 116 is movably abutted against the water pipe 113 to open or close the water outlet of the water pipe 113.

[0040] The water inlet assembly 1 also includes a water inlet drive mechanism 8, which is used to open or close the pressure relief hole 115 according to the water level of the toilet water tank 5. If the water level of the toilet water tank 5 is low and water inlet or water replenishment is required, the water inlet drive mechanism 8 will open the pressure relief hole 115 to change the internal pressure of the pressure relief chamber 117. At this time, the water stop gasket 116 will open the water pipe opening of the water pipe 113 due to the pressure difference factor, so that the water flow of the water inlet flows into the water inlet chamber 12 through the water pipe 113 under the action of water pressure, and then the water flows through the drain pipe 13 to the toilet water tank 5, realizing the water inlet or water replenishment function. At the same time, the water flow will flow through the hydroelectric generator 132 to realize self-powered operation, which is efficient and energy-saving. When the water level of the toilet water tank 5 reaches the preset water level, the water inlet drive mechanism 8 will close the pressure relief hole 115, so that the water stop gasket 116 will re-close the water pipe opening to stop the water inlet or water replenishment function.

[0041] When flushing, the wireless control module 41 controls the water circuit switch device 42 to conduct the channel between the outlet pipe 14 and the water inlet chamber 12 according to the received flushing signal to form a pressure difference. At this time, the water stop gasket 116 will also open the water pipe opening, so that the water flow flows into the water inlet chamber 12 through the water pipe 113 under the action of water pressure, and then the water flows through the outlet pipe 14 to the flushing pipe seat 21 to achieve the flushing operation. Among them, the conduction time of the water circuit switch device 42 is relatively short (such as 3 to 5 seconds, but not limited to this). In the water inlet state of this mode, the amount of water flowing out of the water in the water inlet chamber 12 from the drain pipe 13 is small (much less than the flushing amount), which will not affect the water inlet or water replenishment function of the toilet itself. When the water level of the toilet tank 5 is reduced after flushing and the automatic water inlet or water replenishment function is triggered, the automatic water inlet or water replenishment work can be achieved through the above-mentioned water inlet drive mechanism 8. It should be noted that when the wireless control module 41 does not receive the flushing signal, the water circuit switch device 42 will always disconnect the passage between the water outlet pipe 14 and the water inlet chamber 12 to stop the flushing operation.

[0042] In this embodiment, the water inlet drive mechanism 8 includes a water inlet valve rod 81, a connecting rod assembly 82 and a float mechanism 83. The float mechanism 83 includes a floating head 831 and a floating sleeve 832. One end of the floating sleeve 832 is fixedly sleeved on the water inlet pipe sleeve 114. The other end of the floating sleeve 832 is provided with a floating groove seat 833. The bottom of the floating groove seat 833 is provided with a through hole 834 communicating with the inner cavity of the toilet water tank 5. The floating head 831 is provided in the floating groove seat 833. The two ends of the water inlet valve rod 81 are respectively hinged with one end of the connecting rod assembly 82 and the upper end of the pressure relief valve cover 112, and the other end of the connecting rod assembly 82 is connected to the floating head 831. The end of the water inlet valve rod 81 close to the pressure relief valve cover 112 is provided with a closing portion 811, and the closing portion 811 is movably abutted with the pressure relief valve cover 112 to open or close the pressure relief hole 115. When the water level of the toilet water tank 5 reaches the preset water level, the water in the toilet water tank 5 enters the float through the through hole 834 to make the float head 831 float and move upward, and the end of the water inlet valve stem 81 connected to the float head 831 is tilted, while the other end of the water inlet valve stem 81 connected to the pressure relief valve cover 112 is downward, and the closing portion 811 on the pressure relief valve cover 112 will abut against the pressure relief hole 115 to close the pressure relief hole 115, so that the water stop gasket 116 closes the water pipe opening to stop the water inlet work. At this time, the water flow cannot enter the water inlet chamber 12. On the contrary, when the water level in the toilet tank 5 is low and water needs to be added or replenished, the float head 831 cannot rise, resulting in the end of the water inlet valve stem 81 connected to the float head 831 facing downward, while the other end of the water inlet valve stem 81 connected to the pressure relief valve cover 112 is tilted, and the closing portion 811 on the pressure relief valve cover 112 will open the pressure relief hole 115, thereby allowing the water stop gasket 116 to open the water pipe opening. At this time, water will flow into the water inlet chamber 12 and be discharged into the inner cavity of the toilet tank 5 through the drain pipe 13, thereby realizing water inlet.

[0043] The connecting rod assembly 82 includes a water inlet connection seat 821 and a connecting rod component 822, one end of the connecting rod component 822 is connected to the water inlet connection seat 821, and the other end of the connecting rod is connected to the floating head 831; the upper part of the water inlet connection seat 821 is hinged to one end of the water inlet valve rod 81. When the floating head 831 and the connecting rod move up and down, the corresponding ends of the water inlet connection seat 821 and the water inlet valve rod 81 will be driven to move up and down synchronously to realize automatic water inlet or water replenishment.

[0044] like Figures 9 to 10 As shown, Figures 9 to 10 The schematic diagram of the structure of the second embodiment of the automatic flushing mechanism of a toilet of the present invention is shown. Figures 7 to 8The difference from the first embodiment shown is that the water inlet drive mechanism includes a pressure relief connecting pipe 84, a float switch 85 and a pressure relief connecting pipe 86 arranged on the control box, one end of the pressure relief connecting pipe 86 is connected to the pressure relief hole 115 through the pressure relief connecting pipe 84, and the other end of the pressure relief connecting pipe 86 is connected to the third valve pipe 423 of the water circuit switch device 42; the float switch 85 is installed on the water inlet pipe sleeve, and the float switch 85 is used to detect the water level in the toilet water tank in real time and send a detection signal to the wireless control module. When the float switch 85 detects that the water level reaches the preset water level, the wireless control module controls the third valve pipe 423 to communicate with the second valve pipe 422 according to the corresponding control signal, so that the pressure relief hole 115 is connected to the water outlet pipe 14, which is equivalent to opening the pressure relief hole 115 and forming a pressure difference. At this time, the water stop gasket will open the water pipe port, so that the water flow enters the water inlet cavity and is discharged from the drain pipe 13, realizing water inlet or water replenishment. On the contrary, the wireless control module can also control the third valve tube 423 to be disconnected from the second valve tube 422, that is, to close the pressure relief hole 115. At this time, since no pressure difference can be formed, the water-stop gasket will close the water pipe opening to stop water inlet or water replenishment.

[0045] like Fig.11 As shown, the present invention also provides a control method for an automatic flushing mechanism of a toilet, which is applied to the automatic flushing mechanism of a toilet, and comprises:

[0046] S101, the wireless control module receives an external input control signal in real time;

[0047] It should be noted that the user can send a control signal to the wireless control module in a wireless manner through an external wireless device, and the wireless control module performs subsequent flushing processing according to the control signal.

[0048] S102, determining whether the control signal is received and whether the control signal is a preset flushing signal, if it is determined to be yes, entering the flushing working mode, executing step S103, if it is determined to be no, entering the standby working mode, and returning to step S101;

[0049] It should be noted that when the control signal is a preset flushing signal, the wireless control module enters the flushing working mode, otherwise it enters the standby working mode and continues to wait for the required control signal.

[0050] S103, the wireless control module controls the water channel switch device to connect the channel between the water outlet pipe and the water inlet chamber, so that water flows from the water outlet pipe to the flushing pipe seat;

[0051] S104. When water enters the flush pipe seat, the water flow in the flush pipe seat will push the flush drive assembly to move, and the flush drive assembly will press the flush valve to enable the flush valve to work.

[0052] It should be noted that when entering the flushing working mode, the wireless control module will control the water circuit switch device to maintain the open state for a preset time to connect the channel between the water outlet pipe and the water inlet chamber, so that water flows into the flush pipe seat; when the flush pipe seat is filled with water, the water flow pushes the flush drive assembly to move under the action of water pressure, so that the flush drive assembly presses the flush valve to achieve automatic flushing. Among them, the preset time is relatively short. In the water inlet state of this mode, the amount of water flowing out of the water in the water inlet chamber from the drain pipe is small (far less than the flushing amount), which will not affect the water inlet or water replenishment function of the toilet itself. When the water level of the toilet tank is lowered after flushing and the automatic water inlet or water replenishment function is triggered, the automatic water inlet or water replenishment can be achieved through the above-mentioned water inlet drive mechanism.

[0053] Preferably, after the step of entering the standby working mode, the step further includes: performing standby timing; judging whether the standby time reaches a preset time, if it is judged to be yes, entering the super power saving mode, if it is judged to be no, continuing to execute step S101.

[0054] It should be noted that when the standby timer reaches the preset time, it enters the super power saving mode, and the wireless main control module is in a dormant state. When activation is required, the user can manually press the flush button to achieve the flushing operation. When the automatic water inlet or water replenishment function is triggered after flushing, the wireless main control module will be activated and enter the normal working mode due to the power generation of the hydroelectric generator, and continue to wait for the required control signal to achieve automatic flushing.

[0055] In summary, the present invention constructs a flushing drive water circuit connected to the flush pipe seat between the water inlet valve seat and the control box, and provides water flow driving force for the flushing drive component in the flush pipe seat through the flushing drive water circuit, so as to push the flushing drive component to move and press the flushing valve, so that the flushing valve is opened to realize the flushing operation. The wireless control module can control the operation of the water circuit switch device according to the received control signal, so that the water circuit switch device controls the on-off state of the flushing drive water circuit, thereby controlling the flushing valve to open or close, realizing automatic flushing operation, and the control method is simple and the operation is convenient. The present invention adopts the above-mentioned mechanical flushing drive method to greatly reduce the cost of the flushing structure, and the water flow and water pressure as the flushing driving force can greatly improve the flushing power, ensure good flushing effect, and effectively eliminate the hidden danger of water seepage in the flushing mechanism, reducing the difficulty of production and manufacturing and production and maintenance costs.

[0056] In addition, the present invention has various functions and can realize self-generation, effectively improving the endurance performance of the product. There is no need to frequently replace the power supply battery, making the product energy-efficient and environmentally friendly. It can also realize automatic water inlet or water replenishment function, which can improve the user's comfort.

[0057] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope of the present invention.
