[0028] To make the objectives, technical solutions, and advantages of the present invention more clearly apparent, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that any directional terms such as "up," "down," "left," "right," "front," "back," "inside," and "outside" that appear or will appear in this document are based solely on the accompanying drawings and are not intended to limit the present invention.

[0029] like Figures 1 to 6 As shown, Figures 1 to 6 The schematic diagram shows the structure of a first embodiment of an automatic flushing mechanism for a toilet according to the present invention, comprising a water inlet assembly 1 and a flushing mechanism 2 disposed within the toilet tank 5. The water inlet assembly 1 includes an inlet valve seat 11, one end of which is connected to the water inlet pipe 3 to allow water to flow in. The inlet valve seat 11 defines an inlet cavity 12 that communicates with the water inlet pipe 3. A drain pipe 13 and an outlet pipe 14 are provided on the inlet valve seat 11. The inlet cavity 12 communicates with the drain pipe 13 and the outlet pipe 14, respectively. The drain pipe 13 is used to discharge water into the inner cavity of the toilet tank 5, thereby achieving the water storage or replenishment function of the toilet tank 5. The flushing mechanism 2 includes a flushing pipe seat 21, one end of which is provided with a flushing drive assembly 22. The other end of the flushing pipe seat 21 is connected to the water outlet pipe 14 through a pipe, so that water flows into the flushing pipe seat 21 through the water outlet pipe 14. The flushing drive assembly 22 can drive the flushing valve 7 to open under the push of the inlet water flow; one end of the water inlet valve seat 11 is provided with a control box 4, which includes a wireless control module 41 and a water circuit switch device 42. 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, 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 inflow and non-water inflow 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 flush drive waterway between the water inlet valve seat 11 and the control box 4, connected to the flush pipe seat 21. This flush drive waterway provides water flow driving force to the flush drive assembly 22 in the flush pipe seat 21, thereby driving the flush drive assembly 22 to move and press the flush valve 7, causing the flush valve 7 to open and achieve flushing. A wireless control module 41 controls the operation of a waterway switch device 42 based on received control signals, causing the waterway switch device 42 to control the on / off state of the flush drive waterway, thereby controlling the flush valve 7 to open or close, achieving automatic flushing. The present invention utilizes the aforementioned mechanical flush drive method, significantly reducing the cost of the flushing structure. Using water pressure as the flushing drive force significantly improves flushing power (the national water pressure standard is: 0.2 kPa-0.6 kPa), ensuring excellent flushing effectiveness, and effectively eliminating the potential for water seepage in the flush mechanism 2, reducing manufacturing difficulty 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 provided on either side of the bottom of the flush button 6 of the toilet tank 5. Both push rods 61 abut against the flush valve 7, and the flush button 6 presses the flush valve 7 via the push rods 61 to achieve flushing. A fixed mounting assembly 23 is provided on the outside of the flush pipe seat 21. Each fixed mounting assembly 23 is mounted on a push rod 61 on one side of the flush button 6. The flush button 6 is movably connected to the toilet tank 5. The driving end of the flush drive assembly 22 movably abuts against one bottom edge of the flush button 6. When water enters the flush pipe seat 21, the incoming water flow pushes the flush drive assembly 22 to move, causing the driving end of the flush drive assembly 22 to lift one bottom edge of the flush button 6, thereby flipping the flush button 6 to the other side. At this time, the push rod 61 on the other side of the flush button 6 presses downward on the flush valve 7, causing it to open and achieve automatic flushing.

[0033] Among them, the fixed installation component 23 includes a clamping part 231 and a locking part 232, and the clamping part 231 includes two clamping plates 233. The two clamping plates 233 are locked and fixed on the corresponding pushing rod 61 through the locking part 232 to achieve relative fixed installation of the flush pipe seat 21 and the flushing mechanism 2.

[0034] Specifically, if Figure 2 、 Figure 5 and Figure 6 As shown, a propulsion chamber 24 is provided at one end of the flush pipe seat 21, and a water inlet port 25 is provided at the other end thereof, communicating with the propulsion chamber 24. The water inlet port 25 is connected to the water outlet pipe via a pipe. The flush drive assembly 22 is provided within the propulsion chamber 24, and a drive hole 26 is provided at one end of the propulsion chamber 24. A drainage hole 27 is provided between the propulsion chamber 24 and the water inlet port 25. The drainage hole 27 drains water into the inner cavity of the toilet tank 5 to discharge the inlet water flow. The flush drive assembly 22 is movable within the propulsion chamber 24, and the drive end of the flush drive assembly 22 can pass through the drive hole 26 and movably abut against the bottom edge of one side of the flush button 6. When water enters the water inlet port 25 of the flush pipe seat 21, it flows into the propulsion chamber 24, pushing the flush drive assembly 22 within the propulsion chamber 24. This causes the drive end of the flush drive assembly 22 to lift the flush button 6, pressing the flush valve, and achieving automatic flushing. When water stops flowing, the flush drive assembly 22 resets, closing the flush valve and stopping the flushing process. The diameter of the drain hole 27 is much smaller than that of the water inlet port 25, ensuring sufficient water pressure to propel the flush drive assembly 22 during water inflow, thereby ensuring stable automatic flushing.

[0035] In order to improve the automatic flushing effect, such as Figures 5 to 6 As shown, the flush drive assembly 22 includes a propulsion rod 221 and a spring member 222. The propulsion rod 221 includes a propulsion head 223 and a push rod portion 224. The propulsion head 223 can move in the propulsion chamber 24. A sealing ring is provided on the outer wall of the propulsion head 223. The propulsion head 223 is sealed with 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 propulsion 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 in contact with the propulsion 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, 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 flush valve; when the water intake stops, under the gradually decreasing water pressure and the reset force of the spring member 222, the propulsion head 223 will accelerate the reset operation to accelerate the closing operation of the flush 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 realize the control of the water inlet state of the flushing pipe seat 21, as Figures 3 to 4 As shown, the control box 4 has a first communication hole 43 and a second communication hole 44 at one end near the water inlet chamber 12. The first communication hole 43 communicates with the water inlet chamber 12, and the second communication hole 44 communicates with the water outlet pipe 14. A first valve pipe 421 of the waterway switch device 42 communicates with the first communication hole 43, and a second valve pipe 422 of the waterway switch device 42 communicates with the second communication hole 44. The waterway switch device 42 is a flush solenoid valve. The waterway switch device 42 controls the on / off state of the first valve pipe 421 and the second valve pipe 422 to control the on / off state between the water outlet pipe 14 and the water inlet chamber 12, thereby controlling the water inflow state of the flush pipe seat 21 and achieving automatic flushing operation of the flush mechanism 2.

[0038] In order to improve the endurance of the product and reduce the frequency of battery replacement, such as Figure 3 As shown, the drainpipe 13 is provided with a mounting base 131, the inner cavity of which is in communication with the inner cavity of the drainpipe 13. A hydroelectric generator 132 is mounted on the mounting base 131. The control box 4 contains a battery module 45, and the wireless control module 41 is electrically connected to the generating end of the hydroelectric generator 132 and the battery module 45, respectively. When water from the water inlet chamber 12 is discharged from the drainpipe 13 into the inner cavity of the toilet water chamber, the water flows through the hydroelectric generator 132, causing the hydroelectric generator 132 to generate electricity. The electricity generated by the hydroelectric generator 132 powers the wireless control module 41 and the battery module 45, thereby improving the battery module 45's endurance and eliminating the need for frequent battery replacement, making the product 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, and 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, and the water inlet pipe port of the water pipe 113 is connected to the water outlet end of the water inlet pipe 3; a pressure relief hole 115 is provided on the pressure relief valve cover 112, and the pressure relief valve cover 11 A water-stop gasket 116 is provided on the inner side. 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. The water-stop gasket 116 movably abuts 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 in the toilet water tank 5 is low and water needs to be added or replenished, the water inlet drive mechanism 8 will open the pressure relief hole 115, causing the internal pressure of the pressure relief chamber 117 to change. At this time, the water stop gasket 116 will open the water pipe opening of the water pipe 113 due to the pressure difference, allowing the incoming water to flow through the water pipe 113 into the water inlet chamber 12 under the action of water pressure. The water then flows through the drain pipe 13 to the toilet water tank 5, achieving water inlet or replenishment. At the same time, the water flows through the hydroelectric generator 132, achieving self-generated electricity and high efficiency and energy saving. When the water level in the toilet water tank 5 reaches a preset level, the water inlet drive mechanism 8 will close the pressure relief hole 115, causing the water stop gasket 116 to re-close the water pipe opening, achieving the function of stopping water inlet or replenishment.

[0041] During flushing, the wireless control module 41 controls the waterway switch device 42 based on the received flush signal to open the passage between the outlet pipe 14 and the water inlet chamber 12, creating a pressure differential. At this point, the water-stop gasket 116 also opens the waterway opening, allowing the incoming water flow to flow through the waterway pipe 113 into the water inlet chamber 12 under the action of the water pressure. The water then flows through the outlet pipe 14 to the flushing pipe seat 21, thereby achieving the flushing operation. The waterway switch device 42 has a short on-time (e.g., 3 to 5 seconds, but not limited thereto). In this water-inflow mode, the amount of water flowing from the water inlet chamber 12 out of the drain pipe 13 is relatively small (far less than the flushing volume), and does not affect the toilet's water inlet or water refilling functions. When the water level in the toilet tank 5 drops after flushing, triggering the automatic water inlet or water refilling function, the water inlet drive mechanism 8 can automatically achieve the automatic water inlet or water refilling function. It should be noted that when the wireless control module 41 does not receive the flushing signal, the water channel switch device 42 will continue to 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 stem 81, a connecting rod assembly 82, and a float mechanism 83. The float mechanism 83 includes a float head 831 and a float sleeve 832. One end of the float sleeve 832 is fixedly mounted on the water inlet pipe sleeve 114. The other end of the float sleeve 832 is provided with a float groove seat 833. The bottom of the float groove seat 833 is provided with a through hole 834 that communicates with the inner cavity of the toilet water tank 5. The float head 831 is located in the float groove seat 833. The two ends of the water inlet valve stem 81 are respectively hinged to one end of the connecting rod assembly 82 and the upper end of the pressure relief valve cover 112. The other end of the connecting rod assembly 82 is connected to the float head 831. The end of the water inlet valve stem 81 near the pressure relief valve cover 112 is provided with a closing portion 811. The closing portion 811 movably abuts against the pressure relief valve cover 112 to open or close the pressure relief hole 115. When the water level in the toilet tank 5 reaches the preset water level, the water in the toilet 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 mouth, thereby stopping 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, and the other end of the water inlet valve stem 81 connected to the pressure relief valve cover 112 tilting up, 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 to 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 portion of the water inlet connection seat 821 is hinged to one end of the water inlet valve stem 81. When the floating head 831 and the connecting rod move up and down, they will drive the corresponding ends of the water inlet connection seat 821 and the water inlet valve stem 81 to move up and down synchronously, thereby achieving automatic water inlet or water replenishment.

[0044] like Figures 9 to 10 As shown, Figures 9 to 10 The schematic diagram of the second embodiment of the automatic flushing mechanism of a toilet of the present invention is shown. Figures 7 to 8The first embodiment shown differs in that the water inlet drive mechanism includes a pressure relief connecting pipe 84, a float switch 85, and a pressure relief connecting pipe 86 mounted on the control box. One end of the pressure relief connecting pipe 86 communicates with the pressure relief hole 115 through the pressure relief connecting pipe 84, and the other end of the pressure relief connecting pipe 86 communicates with the third valve pipe 423 of the water circuit switch device 42. The float switch 85 is mounted on the water inlet pipe sleeve and is used to detect the water level in the toilet tank in real time and transmit a detection signal to the wireless control module. When the float switch 85 detects that the water level has reached a preset 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, thereby connecting the pressure relief hole 115 with the water outlet pipe 14. This effectively opens the pressure relief hole 115 and creates a pressure differential. At this point, the water-stop gasket opens the water pipe opening, allowing water to enter the water inlet chamber and be discharged from the drain pipe 13, achieving 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 Figure 11 As shown, the present invention also provides a smart toilet, comprising a toilet body 9 and the above-mentioned toilet automatic flushing mechanism 91 , wherein the toilet automatic flushing mechanism 91 is arranged in the toilet body 9 .

[0046] In summary, the present invention constructs a flushing drive water path between the water inlet valve seat and the control box, which is connected to the flush pipe seat. The flushing drive water path provides water flow driving force to the flushing drive assembly in the flush pipe seat, thereby pushing the flushing drive assembly to move and press the flush valve, causing the flush valve to open and realize flushing. The wireless control module can control the operation of the water path switch device according to the received control signal, so that the water path switch device controls the on-off state of the flushing drive water path, thereby controlling the flush valve to open or close, realizing automatic flushing. 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. The use of water flow and water pressure as the flushing drive 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.

[0047] In addition, the utility model has diverse 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.

[0048] The above disclosure is only a preferred embodiment of the present invention, which certainly cannot be used to limit the scope of the rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
