DETAILED DESCRIPTION

[0018] In order to further explain the technical solution of the present invention, the present invention is described in detail below through specific embodiments.

[0019] refer to Figure 1-5 As shown, the present invention discloses an energy storage type seat-leaving automatic flushing system, comprising a fixed seat 1, a first slider 2, a second slider 3, a third slider 4, a first spring 5, a second spring 6, a movable seat 7, a first blocking member 8, a second blocking member 9, a third spring 10, a first hydraulic device 20 and a second hydraulic device 30; The fixing seat 1 is the fixed part of the automatic flushing system, which cannot be moved after installation and is used to assemble other accessories of the automatic flushing system; a slideway 11 is arranged in the fixing seat 1; The first slider 2, the second slider 3 and the third slider 4 are slidably fitted in the slideway 11 in sequence; the same-direction surfaces of the first slider 2 and the second slider 3 are respectively concave to form a first cavity 21 and a second cavity 31, and a step 32 is provided on a side of the second cavity 31 close to the first slider 2; The first spring 5 and the second spring 6 are respectively arranged between the first slider 2 and the second slider 3, and between the second slider 3 and the third slider 4; The movable seat 7 is movably fitted outside the fixed seat 1, and a first blocking member 8 and a second blocking member 9 are installed thereon, which move synchronously with the movable seat 7. The ends of the first blocking member 8 and the second blocking member 9 penetrate into two through holes 12 provided on the surface of the fixed seat 1 and are movably inserted into or separated from the first cavity 21 and the second cavity 31 respectively as the movable seat 7 moves; The third spring 10 is disposed between the movable seat 7 and the fixed seat 1, and is used to provide elastic force to reset the movable seat 7 in a direction away from the fixed seat 1, so that the first blocking member 8 and the second blocking member 9 have a tendency to separate from the corresponding cavity; The output ends of the first hydraulic device 20 and the second hydraulic device 30 act on the first slider 2 and the movable seat 7 respectively. The hydraulic power of the two is the first water bag 201 and the second water bag 301 respectively arranged on the toilet seat. When the user sits down, the first water bag 201 and the second water bag 301 are pressurized and output power, so that the first hydraulic device 20 and the second hydraulic device 30 push the first slider 2 and the movable seat 7 respectively. The third slider 4 is in transmission connection with the mechanical flushing mechanism of the toilet, so that when the third slider 4 is pushed, power can be output to activate the mechanical flushing mechanism of the toilet.

[0020] Through the above scheme, the present invention arranges the water bags of the first hydraulic device 20 and the second hydraulic device 30 on the toilet seat. When the user sits down, the water in the water bags can be squeezed out to enable the two hydraulic devices to output power, respectively drive the first slider 2 and the movable seat 7 and link the second slider 3, so that the first blocking member 8 and the second blocking member 9 are respectively inserted into the first cavity 21 and the second cavity 31 to store energy for the first spring 5; and when the user leaves the seat, the liquid pressure decreases, and the first slider 2 and the movable seat 7 begin to reset. Since a step 32 is provided in the second cavity 31, the second blocking member 9 can release the limitation of the second slider 3 before the first blocking member 8. When the first blocking member 8 is still limiting the first slider 2, a part of the energy stored in the first spring 5 is released to drive the second slider 3 to move in the direction of the third slider 4, thereby causing the third slider 4 to output power outward to open the mechanical flushing mechanism of the toilet, thereby achieving The purpose of automatic flushing after the user leaves the seat is achieved; thereafter, when the movable seat 7 continues to reset and drives the first blocking member 8 to disengage from the first cavity 21, the reaction force of the mechanical flushing mechanism of the toilet on the third slider 4 causes the first spring 5 together with the first slider 2 to reset to the initial position, completing the entire automatic flushing action process; according to the above action process, the automatic flushing system of the present invention can be installed on any type of toilet (both ordinary and intelligent) for upgrading and transformation, and the third slider 4 is linked with the mechanical flushing mechanism of the toilet to realize the automatic opening of the water tank / water bag drain port, and realize automatic drainage and flushing after the user finishes using the toilet and leaves the seat; the present invention is a purely mechanical structure, does not require electricity to provide power, is more convenient to use, and has a simple structure and low cost, which is conducive to market promotion; in addition, the present invention can also adjust the delay time of delayed flushing by adjusting the internal flow of the second hydraulic device, which is more flexible.

[0021] Specific embodiments of the present invention are shown below.

[0022] The surface of the fixed seat 1 is detachably mounted with a mounting seat 40 by means of screw locking, snap connection, etc., and the movable seat 7 is slidably fitted in the mounting seat 40; the second hydraulic device 30 is detachably mounted on the mounting seat 40 by means of screw locking, snap connection, etc. In the corresponding structure, the movable seat 7 can be guided by the clearance fit between the movable seat 7 and the mounting seat 40, or by designing a guide rail mechanism between the two.

[0023] Mounting portions 71 for mounting the first blocking member 8 and the second blocking member 9 are respectively disposed on both sides of the movable seat 7 .

[0024] Furthermore, the above-mentioned mounting portion 71 is a groove structure, and the opening of the mounting portion 71 is detachably mounted with a limiting cover 72 by means of a snap connection or the like; the end of the first blocking member 8 / the second blocking member 9 away from the fixed seat 1 is inserted into the mounting portion 71 and the limiting cover 72; a fourth spring 73 is arranged in each mounting portion 71, and the fourth spring 73 is sleeved on the first blocking member 8 / the second blocking member 9, and its two ends respectively abut against the limiting cover 72 and the limiting rings on the peripheral surface of the first blocking member 8 / the second blocking member 9, so that the elastic force of the fourth spring 73 can drive the first blocking member 8 / the second blocking member 9 to move toward the direction of the fixed seat 1. The installation of the first blocking member 8 and the second blocking member 9 is achieved through the installation portion 71, the limiting cover 72, the fourth spring 73 and other structures. The fourth spring 73 can be used to achieve buffering after the first blocking member 8 abuts against the first slider 2. When the movable seat 7 moves toward the fixed seat 1 with the first blocking member 8, the fourth spring 73 will be compressed to store energy. When the first blocking member 8 is pushed so that the first cavity 21 is located directly below the first blocking member 8, the fourth spring 73 elastically resets the first blocking member 8 to insert it into the first cavity 21, thereby making the corresponding structural design more compact and reducing the volume of the entire automatic flushing system for easy installation and application in the later stage.

[0025] Secondly, the edge of the step 32 near the side wall of the second cavity 31 is provided with a first stopper 33, and the side surface of the bottom end of the second stopper 9 is provided with a second stopper 91 which is opposite to the first stopper 33 in normal state. In actual use, the first water bag 201 and the second water bag 301 may have the problem of the order of the pressure points, especially when the first water bag 201 and the second water bag 301 are stressed first, the water may start to drain when the user sits down. In this way, the second stopper 91 is provided to block the first stopper 33 in normal state so that the second slider 3 cannot slide and the third slider 4 cannot be driven when the movable seat 7 is not pressed down, and the above problem can be avoided. When the second stopper 9 is pressed down along with the movable seat 7, the second stopper 91 no longer blocks the first stopper 33.

[0026] In addition, the first cavity 21 is a groove structure formed on the surface of the first slider 2, and the second cavity 31 is a through hole structure formed on the surface of the second slider 3, which can give the second blocking member 9 a larger moving stroke.

[0027] The inner cavity of the first hydraulic device 20 is provided with a first diaphragm 202; the first diaphragm 202 divides the inner cavity of the first hydraulic device 20 into two, and one side of the first diaphragm 202 is connected to the first water bag 201, and the other side thereof is provided with a first piston rod 203, and force is applied to the first piston rod 203, and the end of the first piston rod 203 abuts against the first slider 2. In this embodiment, the first hydraulic device 20 is screwed to the end of the fixing seat 1 by screws.

[0028] The inner cavity of the second hydraulic device 30 is provided with a second diaphragm 302 ; the second diaphragm 302 divides the inner cavity of the second hydraulic device 30 into two, and one side of the second diaphragm 302 is connected to the second water bag 301 , and the other side thereof applies force to the rod 74 of the movable seat 7 .

[0029] Furthermore, a one-way valve 303 is provided between the second diaphragm 302 and the second water bag 301, and the one-way valve 303 only allows water to flow from the second water bag 301 to the second diaphragm 302; the second hydraulic device 30 is also provided with a connecting pipe 304, and the two ends of the connecting pipe 304 are respectively connected to the two sides of the one-way valve 303. When the second water bag 301 is squeezed, water can flow to the second diaphragm 302 through the one-way valve 303 and the connecting pipe 304 so that the water pressure acts on the second diaphragm 302, thereby achieving the purpose of driving the movable seat 7; and when the pressure of the second water bag 301 is unloaded (i.e. the user leaves the seat), the water flow can only flow back to the second water bag 301 through the connecting pipe 304, and the inner diameter of the connecting pipe 304 determines the reflux flow of the second hydraulic device 30, i.e. controls the reset time of the movable seat 7, so by replacing the connecting pipe 304 with different inner diameters, it is possible to control and adjust the delay time of the delayed flushing.

[0030] When the present invention is installed in a smart toilet, such as a pressure flushing system of a smart toilet, the above-mentioned mechanical flushing mechanism may include a guide seat 50, an adapter 60, a sealing cover 70, a sealing diaphragm 80, a fourth slider 90, a pressure relief pipe 100 and a sealing spring 200; the guide seat 50 and the adapter 60 are detachably mounted on the fixed seat 1 by means of screw locking, snap connection, etc., the sealing cover 70 is mounted on the adapter 60 and faces the guide seat 50; a guide groove 501 is provided in the guide seat 50, and a pressure relief port 601 is provided on the adapter 60; the sealing diaphragm 80 is provided between the sealing cover 70 and the adapter 60; the fourth slider 90 is slidably fitted in the guide groove 501, and is provided with a driving rod 901 movably penetrated through the sealing cover 70 and abutting against the sealing diaphragm 80, and the fourth slider 90 is transmission-connected with the third slider 4; one end of the pressure relief pipe 100 penetrates the adapter 60, and the other end thereof is connected to the pressure bag pressure relief device of the pressure flushing system; the sealing spring 200 is arranged between the guide groove 501 and the fourth slider 90, and is used to drive the fourth slider 90 so that the driving rod 901 pushes the sealing diaphragm 80 to block the end of the pressure relief pipe 100. In the standby state, the fourth slider 90 can be driven by the elastic force of the sealing spring 200, so that the sealing diaphragm 80 blocks the end of the pressure relief pipe 100. When the fourth slider 90 compresses the sealing spring 200 under the linkage action of the third slider 4, the end of the pressure relief pipe 100 is opened, so that the pressure relief device (generally an open valve) of the pressure flushing system drains water, and the discharged water is discharged through the pressure relief port 601, and the pressure bag also starts to drain water after the pressure relief device is opened.

[0031] Furthermore, a lever 300 is arranged between the fourth slider 90 and the third slider 4, and both ends of the lever 300 are rotatably connected in the third slider 4 and the fourth slider 90 respectively, and a rotating shaft and a sliding groove for sliding cooperation of the rotating shaft are arranged between the third slider 4 / fourth slider 90 and the end of the lever 300, so as to realize the transmission connection between the third slider 4 and the fourth slider 90, and convert the linear movement of the third slider 4 into the linear movement of the fourth slider 90 through the lever 300.

[0032] The end of each spring of the present invention and its two matching accessories can be positioned by setting a columnar and groove structure between them to ensure the functional stability of the spring.

[0033] See also Figure 3-5 , the working principle of the present invention is: (1) When the user sits on the seat ring, the first hydraulic device 20 drives the first slider 2 to make the first spring 5 store energy, and at the same time the second hydraulic device 30 drives the movable seat 7 to make the first blocking member 8 and the second blocking member 9 fall into the preset positions of the first cavity 21 and the second cavity 31 respectively, and the third spring 10 stores energy; at this time, due to the limiting effect of the second blocking member 9, the third slider 4 has not moved, and the mechanical flushing mechanism is in a standby state; (2) When the user leaves the seat ring: Initially, the first blocking member 8 and the second blocking member 9 play a limiting role, and the first spring 5 maintains an energy storage state; the third spring 10 drives the movable seat 7 to slowly reset, so that the second blocking member 9 slowly moves in the unhooking direction until the preset time is up, and the second blocking member 9 moves to the unhooking position, that is, moves above the step 32, and no longer limits the second slider 3, then the energy stored in the first spring 5 is released and acts on the third slider 4, so that it compresses the sealing spring 200 through the lever 300 and links the fourth slider 90, so that the sealing spring 200 is energized and the pressure relief device of the pressure bag is opened, thereby realizing the automatic flushing function; (3) During the flushing process, the movable seat 7 continues to reset until the first blocking member 8 moves to the unhooking position, and the first spring 5 pushes the first slider 2 to reset. Under the action of the sealing spring 200 and the lever 300, the first spring 5 resets to the initial position, and the sealing spring 200 resets to the starting position synchronously, and the pressure relief device of the pressure bag is closed; in addition, the third spring 10 also resets to the initial position.

[0034] When the present invention is installed in an ordinary toilet, the third slider 4 can directly act on the button or drain valve of the water tank. When the third slider 4 is driven by the energy stored in the first spring 5, the button can be pressed or the drain valve can be opened to realize automatic flushing. Figure 6The above-mentioned mechanical flushing mechanism may include an adapter seat 400, a pendulum block 500, a pull rope 600, a drain valve 700 and a torsion spring 800; the adapter seat 400 is relatively stationary with the fixed seat 1; the pendulum block 500 is swingably fitted in the adapter seat 400; the third slider 4 is provided with a push rod 41 which penetrates into the adapter seat 400 and abuts against one end of the pendulum block 500, and the other end of the pendulum block 500 is connected to the upper end of the pull rope 600; the lower end of the pull rope 600 is connected to the valve plug 7001 of the drain valve 700, and the valve plug 7001 is used to movably block the drain port 7002 of the drain valve 700, and when the drain port 7002 is in an open state, the toilet tank starts to drain; the torsion spring 800 acts on the pendulum block 500 to reset it. Figure 6 Taking the direction in as an example, when the third slider 4 is pushed and moves to the right, it will push against the left end of the pendulum block 500 to make its right end swing to the upper right direction, thereby pulling up the valve plug 7001 and opening the drain port 7002; and after the third slider 4 is reset, the pendulum block 500 will be reset under the elastic force of the torsion spring 800, and the valve plug 7001 will be reset at the same time.

[0035] The above embodiments and drawings do not limit the product form and style of the present invention. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present invention.
