Gear box, water closet and control method for controlling opening and closing of cover and/or seat of water closet

Abstract

The invention discloses a gear box. The gear box comprises a detection control unit and a box body which is provided with a driving motor and a reduction gear set, wherein the reduction gear set comprises an input end reduction gear connected with a motor output shaft of the driving motor and an output end reduction gear for outputting torque of the driving motor; the input end reduction gear is provided with a speed and direction detection unit for detecting rotation speed and rotation direction of the input end reduction gear; the speed and direction detection unit is connected to a detection control unit through a wiring harness; the output end reduction gear is provided with a position detection unit for detecting a rotation position of the output end reduction gear; the position detection unit is connected to the detection control unit through the wiring harness. The invention also discloses a water closet and a control method for controlling opening and closing of a cover and / or a seat of the water closet.

Description

technical field [0001] The invention relates to the field of driving opening and closing of a toilet in sanitary equipment, in particular to a gear box, a toilet and a control method for controlling the opening and closing of a seat cover and / or a seat ring of the toilet. Background technique [0002] Smart toilets generally use a gear output structure to drive the seat cover and / or seat ring of the toilet to open and close. [0003] The current smart toilet usually uses the voltage output value of a potentiometer-type angle sensor installed on the gear output structure to judge the current rotation angle of the gear in the gearbox, and then judge the current opening or closing angle position of the seat ring and seat cover. , and then adjust the torque of the gear output structure through the above position information. The gear output structure and toilet using the above-mentioned potentiometer type angle sensor have the following disadvantages: [0004] 1. Initializatio...

[0006] 3. It is a contact connection, and long-term use will affect the test accuracy

[0007] The current smart toilet also uses Hall sensors to detect the position of the seat cover and seat ring, but it can only judge whether the seat cover and seat ring are in a horizontal position or a vertical position, and cannot judge the specific position of the seat cover and seat ring. And when judging abnormal situations, the reaction speed is slow
