Gear box, toilet and method for controlling the opening and closing of seat cover and/or seat ring of the toilet

Abstract

The invention discloses a gear box, which includes a detection control unit and a box body on which a drive motor and a reduction gear set are installed. The reduction gear set includes an input end reduction gear connected to the motor output shaft of the drive motor and a The output end reduction gear that outputs the torque of the drive motor, the input end reduction gear is provided with a speed direction detection unit for detecting the speed and steering of the input end reduction gear, the speed direction detection unit is connected through a wire harness As for the detection control unit, the output reduction gear is provided with a position detection unit for detecting the rotation position of the output reduction gear, and the position detection unit is connected to the detection control unit through a wire harness. The invention also discloses a toilet and a control method for controlling the opening and closing of the seat cover and / or the seat ring of the toilet.

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
