Embodiment Construction
[0014] The application structure of the mechanical part of an embodiment of the lifting device of the toilet drain hose of the present invention in the state of putting down the drain hose, such as figure 1 shown. A bedpan 2 is installed in the upper middle front part of the toilet frame 1 . A drainage hose 4 is established between the sewage outlet of the bedpan 2 lower end 21 and the ground drainage pipeline. Both ends of the drain hose 4 are respectively provided with bellows 41, 42. The lifting device of this toilet drain hose is installed on the beam 3 at the toilet frame 1 rear portion.
[0015] The lifting device of the toilet drainage hose includes a DC motor 5, a worm 51, a worm wheel 52, a swing rod 6, an optocoupler 64, a connecting rod 7, a fixed seat 8, a lever 9, a hinged rod 94, a collar 95 and a controller (not shown in the figure).
[0016] The housing 50 of the DC motor 5 is equipped with a speed reducer made up of a worm 51 and a worm wheel 52 meshing wi...

The invention provides a lifting device of a drain hose of a toilet, and relates to electric drainage control devices of toilets. The lifting device comprises a lever which is used for directly lifting up or putting down the waist portion of the drain hose, a connecting rod connected with the supporting point of the lever, a detector for detecting the state of the lever, a motor, a driver and a controller. The motor is a DC motor, and the driver is provided with a speed reducer and a swinging rod. The speed reducer is arranged between a rotating shaft of the DC motor and the swinging rod, and an output shaft of the speed reducer drives the swinging rod to rotate. One end of the swinging rod is hinged to the free end of the connecting rod, and the other end of the swinging rod is provided with a blocking piece. A photoelectric coupler is correspondingly arranged on the rotating track of the blocking piece, and the blocking piece and the photoelectric coupler constitute the detector for detecting the state of the lever. The controller controls rotating of the DC motor according to signals output by the photoelectric coupler. The influence of power outage does not need to be considered, and a mechanical structure is simplified.
Description
technical field [0001] The invention relates to an electric drainage control device for a liftable toilet. Background technique [0002] The drainage of a kind of liftable toilet is realized by the drainage hose between the sewage outlet at the lower end of the bedpan and the ground drainage pipe. The waist of the drain hose is connected with an electric lifting device. When the waist of the drain hose was lifted, a U-shaped pipe segment was formed between the waist of the drain hose and the sewage outlet at the lower end of the bedpan, and the accumulated water therein could isolate the foul smell in the floor drain. When the waist of the drain hose is lowered, the drain hose is obliquely arranged between the sewage outlet at the lower end of the bedpan and the ground drain pipe, forming a smooth drainage channel. In the past, the design of the electric lifting device should consider that in case the waist of the drain hose is put down during a power failure, there must b...
