And the voice prompt device is used for carrying out voice prompt after the cleaning device finishes one cleaning each time in a reciprocating way.

The working principle of the automatic cleaning device for the squatting pan is as follows:

the infrared sensing device is adopted to detect whether a person is in the toilet, the control device controls the operation of each mechanism according to a set program, and after the sweeper is used by a plurality of persons, the control device controls the sweeper to sweep the ground and the squatting pan according to the set program. The cleaning device has two states, the first is to clean the ground without cleaning the squatting pan. The second is to clean both the floor and the squatting pan. The toilet is easy to leave dirt on the ground, and according to the characteristic that the squatting pan is not easy to leave the dirt after being flushed every time, the squatting pan is cleaned for 2 to 4 times every day, the toilet is cleaned for 1 time every 5 to 10 people every time, and the toilet is cleaned for not less than 2 times every day. When only the floor of the toilet is cleaned, the sweeper returns for 5 to 10 seconds, and when the floor of the toilet and the squatting pan are cleaned, the sweeper returns for 10 to 20 seconds. The water consumption for cleaning the ground is 0.3 liter, and the water consumption for cleaning the squatting pan is 0.2 liter. The control device sets a program, and the cleaning is started after the set number of users is reached, and the cleaning vehicle is cleaned once again and again each time. The two ends of the sweeper are provided with guide rails, or only one end of the sweeper is provided with a guide rail, wherein a driving device is arranged on the guide rail on one side, and a direct current motor, a synchronous belt transmission mechanism or a lead screw and nut transmission mechanism drives the sweeper to travel. The rotatable front spiral brush can be provided with a chain wheel and chain device at one end or two ends, and a ratchet wheel mechanism is arranged in the chain wheel and is a unidirectional rotation (unidirectional bearing) mechanism. When the guide rails at two sides of the sweeper are provided with chains, one side of the chain is arranged below the chain wheel and meshed with the chain, and the other side of the chain is arranged above the chain wheel and meshed with the chain. When the sweeper travels forwards, the chain wheel on the lower side of the chain rotates forwards and drives the front spiral brush to rotate forwards, and the chain wheel on the upper side of the chain idles backwards and does not interfere with the forward rotation of the front spiral brush. When the sweeper travels backwards, the chain wheel on the upper side of the chain forwards and drives the front spiral brush to rotate in the forward direction, and the chain wheel on the lower side of the chain idles backwards without interfering the forward rotation of the front spiral brush. That is, when the chain wheel and chain devices are arranged on two sides of the front spiral brush, the front spiral brush always moves forwards no matter the sweeper moves forwards or backwards. When the chain is arranged on one side of the sweeper, the chain is arranged below the chain wheel and is occluded with the chain wheel, the chain wheel rotates forwards and drives the front spiral brush to rotate forwards when the sweeper travels forwards, the chain wheel idles backwards when the sweeper travels backwards, and the front spiral brush cannot rotate due to friction between the front spiral brush and the ground and blocking of a scraper of the front spiral brush, so that the front spiral brush becomes a fixed brush to clean the ground. That is, when the chain wheel and chain device is installed on one side of the front spiral brush, the front spiral brush rotates forwards when the sweeper travels forwards, and the front spiral brush does not rotate when the sweeper travels backwards. The sprocket and chain arrangement may also be a rack and pinion arrangement.

The positioning turntable and the photoelectric switch control the stop position of the brush of the squatting pan; the squatting pan brush is arranged on two corresponding sides of the lower end of the rotating shaft and is flat, and the squatting pan brush needs to be parallel to the cross section of the sweeper when not working, so that the filament row brush is prevented from interfering with other components.

The collection device is concentrated to the junk that is equipped with above the motor sweeper, and the abandonment case apron adopts infrared induction control switch apron, and infrared inductor installs on the apron, facilitates the use. The waste is collected in a concentrated mode, automatic concentrated collection of the waste among a plurality of toilets is achieved, and the waste is convenient to clean and transport outside. In order to reduce the space occupied between toilets and reduce the thickness of the waste centralized collection device as much as possible, the belt conveyor is started once every time no less than 2 times of waste is thrown in according to different quantities between toilets in each group. The sweeper walking mechanism is arranged on one side of the guide rail and is driven by a synchronous belt pulley or a lead screw nut mechanism and a direct current motor.

The front of the sweeper is provided with a rotatable front spiral brush for sweeping dirt backwards, the rear of the sweeper is provided with a rear fixed brush for sweeping the ground and blocking the dirt swept by the front brush, when the sweeper moves to the position of the squatting pan, the dirt at the middle position falls into the squatting pan, meanwhile, the special nozzles at two sides flush the dirt into the squatting pan, the squatting pan brush moves downwards and brushes the squatting pan in a rotating mode, and when the sweeper leaves the squatting pan, the squatting pan brush stops rotating and moves upwards. The sweeper is arranged at the back of the squatting pan, a special nozzle and an ultraviolet disinfection lamp are arranged in the sweeper, and the sweeper goes back and forth once every time and has voice prompt. The rotary power of the front spiral brush comes from a traveling mechanism of the sweeper and is rotated by a chain wheel and chain device or a gear and rack device. The squatting pan brush device is driven by independent direct current motors respectively for lifting and rotating. The belt conveyor of the waste centralized collecting device is driven by a direct current motor. The walking distance of the sweeper is determined by a set travel switch, and the lifting of the brush of the squatting pan is also determined by the set travel switch. The upper part of the sweeper is provided with a waste centralized collecting device, automatic centralized collection of waste in a plurality of toilets is realized, the opening and closing of a waste collecting cover plate in each toilet is controlled by an infrared induction switch, and the belt conveyor conveys the waste into a centralized collecting barrel.
