[0035] exist Figures 15-17 The seat control switch 3 includes: a housing 54 disposed in the lower groove of the toilet seat 1, which is integrally formed with or separately from the toilet seat; in this embodiment, it is separately formed; a shaft 50 disposed at the front end inside the housing 54; a pressure handle 49 and a sector gear 51 concentrically mounted on the shaft 50; a clutch drive and a clutch follower 52 disposed inside the housing 54; a contact hole 80 disposed on the lower side of the housing 54; and the other end 55 of the flexible shaft 27 sleeve is fixed to the rear end of the housing 54, with its shaft core 30 passing through the through hole of the housing 54 and connected to the rear end of the clutch follower 52.

Other parts are made of metal or plastic; in this embodiment, they are made of metal.
[0036] The working principle of this invention is as follows: The delayed flipper 2 is fixed to the rotating shaft of the toilet seat 1 by the connecting plate 17. The initial position is as follows: the toilet seat is in the lower position, the positioning hole 40 of the bevel gear 4 is equivalent to the 6 o'clock position when viewed from the front of the bevel gear 4 (the same applies below), and the positioning clip 34 of the positioning device is set at the 6 o'clock position. The positioning clip 34 is pushed into the positioning hole 40 by the elastic force of the spring 37 to limit the positioning hole 40. The spring 6 is in the tightened state, and the push-pull device is in the pushed-out state. Its core rod 22 is inserted into the pin hole 36 of the positioning device to position the toilet seat 1.When a person sits on the toilet, their buttocks press down on the handle 49 of the seat control switch 3, bringing it to the lower position. The handle 49 simultaneously drives the sector gear 51 to rotate counter-clockwise. The rack 65 then moves the block 58 backward. The clutch pawl's contact rod 61, being away from the edge of the contact hole 80, rotates clockwise. When the contact rod 61 hits the stop post 64, the clutch pawl stops rotating clockwise. The outwardly protruding locking arc 63, upon contacting the clutch follower 52, causes the clutch pawl to rotate counter-clockwise again. Thus, the outwardly protruding locking arc 63 smoothly engages with the inner locking arc 53 of the clutch follower 52. After using the toilet, one can simply stand up without any further operation. The block 58 moves forward under the push of the spring 57, and the clutch pawl... The convex locking arc 63 will drive the clutch follower 52 to move forward, thereby pulling the shaft core 30 of the flexible shaft 27 forward. The shaft core 30 will also simultaneously pull the positioning chuck 34 out of the positioning hole 40 at the other end. The bevel gear 4 will rotate counterclockwise under the action of the spring 6 to release the spring energy. When the clutch pawl's contact rod 61 hits the contact hole 80, it will rotate counterclockwise, thereby causing the convex locking arc 63 to disengage from the concave locking arc 53. The clutch follower 52 will be pulled back to the limit position by the shaft core 30 under the action of the spring 37 of the positioning device. The positioning chuck 34 will then move forward under the action of the spring 37 to the point where it hits the smooth surface of the bevel gear 4. At this time, the spring 6 has driven the rotating shaft 5 Rotating counterclockwise causes ratchet 7 to rotate counterclockwise, and pawl 78 engages in the ratchet hole of ratchet 7, thus causing pawl wheel 9 to rotate counterclockwise. Pawl wheel 9 drives gear 8 to rotate via gear disk 76, which in turn drives escape wheel 11 to rotate. Escape wheel 11 causes escape fork 12 to swing through an angle. Because escape fork 12 is engaged with balance wheel 13, it also causes balance wheel 13 to swing through a stroke. Balance wheel 13 tightens the hairspring. When the hairspring releases energy, it causes balance wheel 13 to swing through a stroke in the opposite direction. Escape fork 12 is also driven to swing through a stroke in the opposite direction. Escape wheel 11 then rotates through an angle in the opposite direction again. Bevel gear 4 synchronously drives the meshing gear 2. 0 (viewed from in front of gear 20) rotates clockwise. Through the meshing of the dial and grooved wheel 47 of gear 20, gear 18 rotates counterclockwise, causing the push-pull device to retract. When the escape wheel 11 continues to rotate, releasing all the energy from the mainspring 6, the bevel gear 4 rotates counterclockwise to its limit position, with its positioning hole 40 at the 3 o'clock position. The push-pull device also disengages from the pin hole 36 of the positioning device, and the toilet seat 1 is no longer restricted. Under the clockwise rebound force of the torsion spring 15 of the flipping device, the toilet seat 1 automatically flips up to its upper position. At this time, the bevel gear 4 rotates clockwise with the toilet seat 1, and its positioning hole 40 is at the 6 o'clock position, exactly coinciding with the position of the positioning clip 34. The positioning clip 34 then re-engages into the positioning hole 40.The next time you use it, simply press down on the toilet seat 1. The delayed flipper 2 will rotate accordingly, but the bevel gear 4 will be stopped from rotating. This will cause the spring 6 to be wound clockwise, and the ratchet 7 will rotate. However, the pawl gear 9 will not rotate because the pawl 78 has disengaged from the ratchet 7. Instead, the gear 20 will rotate counterclockwise, causing the gear 18 to rotate clockwise. This will push the push-pull device out. When the toilet seat 1 is pressed down to the bottom position, the core rod 22 will engage in the pin hole 36 of the positioning device, and the toilet seat 1 will be stopped. Then, the above process will be repeated. If someone has just finished using the toilet and another man needs to urinate, he can wait for the toilet seat 1 to automatically flip up after the delay, or manually press button 24 to push out the core rod 22, causing the toilet seat to flip up automatically immediately.
[0037] In the latter embodiment of the delay device, the only difference is that: gear 8 drives gear 67 to rotate through shaft 10, gear 67 drives double row gear 68 to rotate, double row gear 68 drives gear 69 to rotate synchronously through large gear, and drives centrifugal friction wheel 72 to rotate through shaft 70. Centrifugal friction claw 74 opens outward under centrifugal force and contacts friction wheel 71 to generate resistance, so as to play the role of deceleration and delay.
