Detailed ways

The relevant details and working principles of the embodiments and embodiments of the present invention will be described below with reference to the accompanying drawings. The flushing valve includes a valve body 3, a valve core and a flushing switch 5, the valve core is arranged in the valve body 3, the water outlet end of the valve body is connected to a drain pipe 4, and the top of the valve core and the valve body are connected to each other. There is a water storage cavity 11 between the valve core and the water outlet end of the valve body. The flush switch includes a frame body 16, a valve stem 20 and an end cover 18. The frame body 16 is provided with a water inlet 25. and the water outlet 21, the inner cavity of the frame body is divided into a sealing section 22 and an unsealing section 23, the unsealing section is larger than the inner diameter of the sealing section, and the inner cavity is stepped. The top of the valve stem 20 and the end cover 18 connection, the bottom end of the valve stem passes through the sealing section 22 and enters the unsealing section 23, the bottom end of the valve stem is in sealing fit with the sealing section, and the outer diameter of the bottom end of the valve stem 20 is larger than the inner diameter of the sealing section 22 , the bottom end of the valve stem will not enter the sealing section and seal the sealing section, so that the sealing section and the unsealing section are separated; the sealing section 22 of the inner cavity is connected to the water outlet 21 of the frame body, and the sealing section 22 of the inner cavity The sealing section 23 is connected to the water inlet 25 of the frame body, the water inlet 25 is connected to the water storage cavity 11 through the water inlet pipe 6, the water outlet 21 is connected to the drain pipe 4 of the valve body through the water outlet pipe 1, and the The valve stem 20 is covered with a spring 19, and the spring is arranged between the end cover 18 and the frame body 16. There is a pressing gap 17 between the frame body and the end cover. When the end cover 18 is pressed, the spring 19 is pressed, and the pressing gap 17 is pressed. It becomes smaller until the end cover 18 contacts the frame body 16. At this time, the sealing surface is opened, the bottom end of the valve stem penetrates into the unsealing section 23, the sealing section of the inner cavity is communicated with the unsealing section, the water storage cavity 11, the water inlet pipe 6, The inner cavity of the valve body, the water outlet pipe 1 and the drainage pipe 4 are connected, and the water in the water storage cavity passes through the water inlet pipe, passes through the inner cavity of the frame body, and then passes through the water outlet pipe, and finally is discharged by the drainage pipe of the valve body. The water is emptied, the valve core moves along the inner wall of the valve body 3, the water outlet of the valve body is opened, and is discharged from the drain pipe 4, see Figure 6; then, the spring 19 pushes the end cover 18 to reset, that is, the valve stem 20 is reset, and the water flow After being cut off, the water outlet pipe 1 stops draining water, and the increase in the water volume in the water storage chamber 11 pushes the valve core to reset, and closes the water outlet end of the valve body, see Figure 5, and the valve is closed at this time. The flush switch of the present invention is connected with the valve body 3 through the water inlet pipe 6 and the water outlet pipe 1, the installation position of the flush switch is no longer restricted, the installation range can be expanded to a greater extent, and the position of the flush switch 5 can be kept away from the valve body 3, this is not only easy to install, but also the bacteria fly up when flushing, which can prevent bacterial infection, and the use is safer and more hygienic; the utility model only needs to gently press the end cover 18 to overcome the elastic force of the spring 19 to open the sealing surface, The water in the water storage cavity is discharged, the end cover is light in weight, and the elastic force required for reset is small, so the force required for pressing the spring is small, which is more convenient for children and the elderly to use.

The inner cavity of the valve body 3 can be arranged vertically or horizontally. If the inner cavity of the valve body is arranged vertically, the valve core moves up and down in the valve body. If the inner cavity of the valve body is arranged horizontally, the valve core is in the valve body. Move left and right, in this embodiment, the valve core is laterally arranged in the valve body 3, the valve core includes a top seat 8, a core body 13, a middle seat 14 and a base 15, and the top seat 8 is provided with the valve The water inlet channel 12 is connected to the water inlet end of the body, and the water inlet channel is unidirectionally connected to the water storage cavity 11, that is, the water in the water inlet channel can enter the water storage cavity, and the water in the water storage cavity cannot Entering the water inlet channel can be achieved through a damping hole. One end of the damping hole is connected to the water inlet channel, and the other end of the damping hole is connected to the water storage cavity. In this embodiment, the top seat 9 is provided with a delay seat. The delay seat is provided with a damping hole, and the damping hole is connected with the water inlet channel and the water storage cavity. Through the damping hole, the water in the water inlet channel can enter the water storage cavity, and the water in the water storage cavity can enter the water storage cavity. In order to prevent the damping hole from being blocked, the damping hole is equipped with a pogo pin 10, the pogo pin is installed on the delay seat 9, and the top seat 8 is in sealing fit with the inner wall of the valve body 3 , the middle seat 14 is sealingly matched with the water outlet of the valve body; when draining, the valve core moves to the right, and the water in the water storage cavity 11 is discharged until the spring needle contacts the valve body, and the spring needle is pressed into the damping When the valve stem 20 of the flush switch is reset, the water in the water inlet channel 12 enters the water storage cavity 11 through the damping hole, and the water in the water storage cavity pushes the valve core to move to the left and After reset, the valve core closes the water outlet of the valve body again. If there is no pogo pin 10, impurities in the water may block the damping hole, causing the spool to fail to reset. Therefore, the setting of the pogo pin extends the service life of the flush valve.

The flushing switch is provided with two groups, which are a large water volume switch 27 and a small water volume switch 26, that is, when a large water volume is required for flushing, press the large water volume switch, and vice versa, press the small water volume switch; the pressing gap ratio of the large water volume switch is The pressure gap of the small water volume switch is large, and the water inlet pipe 6 and the water outlet pipe 1 are also provided with two groups, namely the water inlet pipe 1, the water outlet pipe 1, the water inlet pipe 2 and the water outlet pipe 2, the water inlet pipe 1 and the water inlet pipe 2. Both are connected with the water storage cavity, and the first water outlet pipe and the second water outlet pipe are connected with the drain pipe. The larger the movement stroke of the valve stem 20 and the end cover 18, the more water is discharged. This is because the valve stem 20 goes deep into the unsealing section 23, and the larger the opening of the sealing surface, the greater the water output, and the water storage cavity 11 The more water is discharged inside, the longer the spool moves, and the longer it takes to reset. Therefore, the displacement will be large, and vice versa. In this way, the displacement will be selected according to the demand, which will save energy.
