Automatic opening and closing device and intelligent toilet bowl

Abstract

The invention belongs to the technical field of sanitary ware, in particular to an automatic opening and closing device and an intelligent toilet bowl. The automatic opening and closing device comprises a first gearbox and a second gearbox. The first gearbox comprises a gear structure and a driving motor. A first output gear of the gear structure is arranged on an output shaft, and a first torsionspring is sleeved on the output shaft. A second gear box includes a second box body, one end of the output shaft extends into the second box body, a second input gear is provided on the output shaft,the second input gear is meshed with the second output gear through a sector gear, and a second torsion spring is arranged on the second case under the sector gear. A swivel arm at one end of the second torsion spring is inserted into the sector gear, the other end of the rotating arm is arranged on the second box body, the second output gear is arranged on the transmission bar, and the transmission bar is protruded out of the second box body. The invention increases the force of driving the transmission bar to rotate through the superposition of the torsional forces of the first torsion spring and the second torsion spring, and the driving force is large, so that the automatic take-off and landing of the large-size stool cover can be realized.

Description

Technical field: [0001] The invention belongs to the technical field of sanitary ware, in particular to an automatic opening and closing device and an intelligent toilet. Background technique: [0002] The toilet includes a toilet lid and a seat. The smart toilet is generally equipped with a gear box to control the automatic opening and closing of the toilet lid and the seat. For example, the Chinese utility model patent whose authorized announcement number is CN 202908606 U discloses a transmission motion device for controlling the take-off and landing of the toilet seat and toilet seat in the toilet. The gear box described above is equipped with a transmission mechanism consisting of a group of transmission gears and a DC motor. The output shaft of the DC motor is connected to the worm. The meshed spur gear rotates and transmits the torque to the meshed double gear A and double gear B, and the double gear B meshes with an output gear. The output gear is connected to a tr...
