The rotation type blackboard further comprises a rotation support. The rotation support comprises a rotating shaft part and four telescopic supporting rods which are arranged on the rotating shaft part and extend outwards. The fixing part is sleeved with the rotating shaft part. The rotation type blackboard further comprises a first driver. The first driver is connected with the rotating shaft part and used for driving the rotating shaft part to rotate. A first track and a second track are distributed on the inner circumference of the outer frame in the circumferential direction. Two first blackboard bodies are arranged in the first track. Two second blackboard bodies are arranged in the second track. The first blackboard bodies and the second blackboard bodies are hinged to the telescopic supporting rods respectively and are arranged in the rotating circumferential direction of the telescopic supporting rods at intervals. The first blackboard bodies can slide along the first track, and the second blackboard bodies can slide along the second track. According to the rotation type blackboard, the first blackboard bodies and the second blackboard bodies can be rotated to any position within the range of the outer frame, accordingly, students can watch the blackboard conveniently, and the teaching quality of teachers is improved.

In order to improve the function of a bath tub and achieve the automatic back rub of the bath tub, we add an electric rub towel into the bath tub so that the bath tub can automatically scrub backs and the problem that a traditional bath tub cannot automatically scrub is solved.

The invention relates to the technical field of cleaning and dust removal, and particularly discloses an automobile cleaning device. The automobile cleaning device comprises a motor and a rack. A cylinder is arranged on the rack, and a piston is slidably connected to the interior of the cylinder; a driving mechanism driving the piston to reciprocate is arranged on the rack; a first one-way air inlet valve and a first one-way air outlet valve are arranged at the left end of the cylinder, and the right end of the cylinder is provided with a second one-way air inlet valve and a second one-way airoutlet valve; a first air bag is connected with the first one-way air outlet valve, a box is arranged outside the first air bag, and a first automatic valve is arranged at the air outlet end of the first air bag; a Venturi tube is fixedly arranged on the rack, and the first automatic valve air outlet and and the second automatic valve air outlet end are both communicated with the air inlet of theVenturi tube; the throat part of the Venturi tube is connected with a detergent box. The problem that an existing cleaning device has no foaming function is solved.

The invention relates to an end face cleaner for track pin bushings. The end face cleaner for track pin bushings is characterized by comprising two cleaning support vertical plates, a cleaning support transverse plate, a split brush mechanism, a compressing cylinder and a press plate; the cleaning support transverse plate is fixed between the cleaning support vertical plates; the split brush mechanism is mounted on the cleaning support transverse plate; the compressing cylinder is vertically mounted in the middle of the cleaning support transverse plate; the press plate is mounted below the compressing cylinder. The end face cleaner for track pin bushings is scientific and reasonable in structural design, the end faces of pin bushings can be automatically cleaned by means of brushing, and the end face cleaner for track pin bushings has the advantages of compact structure, high automation level, good cleaning effect and prominent targeted level.

The invention relates to a six-wheel clamping traveling mechanism of a two-sided window cleaner, which mainly comprises a clamping body. An upper shaft seat, a cam supporting shaft, a lower shaft seatand a connecting rod supporting shaft are symmetrically arranged on both sides of the clamping body, wherein the connecting rod supporting shaft is connected with a chucking friction wheel through aconnecting rod body, a cam arranged on the cam supporting shaft is in fit connection with the connecting rod body on a motion path, and a connecting rod handle is fixedly connected with the cam supporting shaft. A cavity used for mounting a window frame is formed in the middle of the clamping body. A driving friction wheel and a driven friction wheel are arranged on the bottom of the cavity, whereinthe driving friction wheel is connected with an output shaft of a motor. The invention has the advantages that: the six-wheel clamping traveling mechanism of the two-sided window cleaner takes a glas s-reinforced plastic window frame as a guide rail to move up and down, and drives a scrubbing cloth mechanism to make left and right synchronous movement through the motor, a constant speed ratio driving gear and a synchronous belt, thereby realizing the automatic cleaning of a glass-reinforced plastic glass window; the six-wheel clamping traveling mechanism of the two-sided window cleaner is characterized in simple structure, strong practicability, convenient operation and high degree of automation.

The invention discloses a self-cleaning robot system and a self-cleaning control method thereof. The system includes a cleaning robot and a cleaning seat. When the cleaning robot judges that the mop needs to be cleaned, it sends out a back-to-seat cleaning signal, and sits on the seat according to the detected guidance signal. After the robot sits on the seat, it performs back-and-forth reciprocating motions according to preset actions, so that the mop and the cleaning part in the cleaning seat can be cleaned. reciprocating friction. The invention can simplify the self-cleaning structure in the system, without adding additional cleaning action mechanism, only need to control the robot to move back and forth on the cleaning seat and control the cleaning part to spray water to realize the automatic scrubbing of the mop. The operation only needs to improve the control program in the aspect of software, and does not need to increase the hardware cost, thereby greatly reducing the system cost and improving the system cost performance.
