[0002] Squat toilets are a common sanitary equipment with many advantages and characteristics. They are suitable for various public places such as railway stations, airports, shopping malls, hospitals, schools, etc. Compared with toilets, squat toilets reduce direct contact between the skin and the toilet bowl, reducing the risk of cross-infection. In addition, when defecation in a squatting position, urine and feces are more easily discharged directly into the toilet bowl, reducing the possibility of splashing and residue. Secondly, it is conducive to maintaining hygiene. Squatting defecation is more in line with the natural physiological structure of the human body, which helps intestinal emptying and prevention of rectal diseases. Squat toilets are usually more affordable and have a longer service life, reducing the operating costs of public places.

[0045] See also Figure 6-Figure 9The circuit trigger device 407 includes a piston Ⅰ4071 movably mounted in the switch chamber, a push shaft Ⅰ4072 is fixedly connected to one side of the piston Ⅰ4071, one end of the push shaft Ⅰ4072 extends into the trigger chamber and is fixedly installed with a push block Ⅰ4073 located on one side of the moving block 4042, and a sealing ring is provided between the push block Ⅰ4073 and the sealing plate 403, and two conductive sheets 4074 are provided on the side of the push block Ⅰ4073 away from the push shaft Ⅰ4072, and the two conductive sheets 4074 are movably connected to the upper and lower sides of the moving block 4042 respectively, and the piston Ⅰ4071 is fixedly connected to the push shaft Ⅰ4072. The other side is fixedly connected with a push shaft II 4075, and the end of the push shaft II 4075 away from the piston I 4071 is fixedly connected with a push block II 4076, and two conductive terminals 4077 are provided on the side of the push block II 4076 away from the push shaft II 4075. The two conductive terminals 4077 are electrically connected to the two conductive sheets 4074 through wires, and sealing sleeves 4078 are provided on the outside of the two wires. The two ends of the sealing sleeve 4078 are sealed at the connection points with the push blocks I 4073 and II 4076, and a throttling groove 4079 is opened on the piston I 4071.

[0046] See also Figure 6-Figure 10 The two conductive terminals 4077 are movably connected to the two conductive springs 408 respectively, and the two conductive springs 408 are electrically connected to a wire respectively, and the two wires electrically connected to the conductive springs 408 are electrically connected to the same circuit as the electromagnet 15. A spring II 17 is provided in the trigger chamber between the movable plate 4041 and the sealing plate 403, and a spring III 18 is provided in the switch chamber between the piston I 4071 and the side cover 402. The switch chamber is filled with transformer oil, which has good pressure resistance, electrical insulation, oxidation resistance, good stability and chemical stability, etc., and does not affect the contact between the conductive terminal 4077 in the trigger chamber and the conductive spring 408.

[0047] See also Figure 6The switch sleeve 401 is provided with a filling chamber 409 connected to the switch chamber. When assembling the switch device 4 of the linkage lock tongue, transformer oil can be injected into the switch chamber through the filling chamber 409, and a sealing cover is provided at one end of the filling chamber 409. A piston II 19 is movably sleeved in the filling chamber 409. A spring IV 20 is provided between the piston II 19 and the inner wall of the filling chamber 409. An active pressing switch 21 is provided on the side of the piston II 19 away from the spring IV 20. One end of the active pressing switch 21 extends out of the sealing cover. The user can press the active pressing switch 21. By pushing piston II 19 to move and utilizing the throttling effect of the throttling groove 4079 on piston I 4071, piston I 4071 can be pushed to move away from one side of the sealing plate 403, so that the conductive block 4043 contacts the conductive sheet 4074, and the conductive terminal 4077 contacts the conductive spring 408, thereby energizing the electromagnet 15 and pushing the large switch on the top of the flushing valve tube 5 downward to actively flush the squat toilet, thereby avoiding unpleasant odors during use that may cause bad sensory problems to the user, and the switch device 4 linked to the lock tongue is arranged in the front to facilitate use.

[0048] When using, Figure 1-Figure 2 As shown, when using the squat toilet, the user will first close the door, and then rotate the lock tongue of the rotary door lock. After the lock tongue of the rotary door lock is rotated 90 degrees, the linkage plate 406 will be pushed to drive the linkage shaft 405 to move (it is also applicable to the horizontal push door lock, the lock tongue of the horizontal push door lock will push the linkage plate 406 to drive the linkage plate 406 to move). Figure 6-Figure 11 As shown, the linkage shaft 405 will push the circuit trigger device 407 to move together, and when the lock tongue is rotated 90 degrees and maintained, as shown in FIG. Fig.11 As shown, the conductive terminal 4077 contacts the conductive spring 408 and makes the conductive spring 408 in a compressed state, while the conductive sheet 4074 is located on one side of the conductive block 4043. At this time, the two conductive sheets 4074 and the two conductive springs 408 are still in an open circuit state, that is, the electromagnet 15 is still in an open circuit state.

[0049] When the user finishes using the squat toilet and opens the door to leave, he will first open the lock tongue, that is, turn the lock tongue in the opposite direction to open the toilet door. Fig.12As shown, the elastic force of spring II 17 will push the moving plate 4041 to reset immediately, so that the rubber ring 4044 contacts the side cover 402 on one side of the trigger chamber, and in the switch chamber, due to the throttling effect of the throttling groove 4079 on the piston I 4071, the elastic force of spring III 18 pushes the throttling groove 4079 to reset slowly, that is, there is a speed difference between the reset movement of the linkage device 404 and the reset movement of the circuit trigger device 407. In this process, the linkage device 404 is reset relative to the circuit trigger device 407, that is, the conductive block 4043 is relative to the conductive sheet. 4074 moves to the left, the conductive block 4043 contacts the conductive sheet 4074, and the two conductive sheets 4074 and the two conductive reed sheets 408 are in a conductive state, that is, the electromagnet 15 is energized to generate a magnetic repulsion force on the magnetic ring 143, which will push the slide plug 9, the lower push rod 10 and the push block 11 downward, thereby pressing the large switch on the top of the flushing valve tube 5, realizing the automatic flushing of the squat toilet, until the elastic force of the spring III 18 pushes the circuit trigger device 407 to move, so that the conductive terminal 4077 is separated from the conductive reed sheet 408, and then the electromagnet 15 is powered off.
