Description

Technical Field

[0001] The utility model relates to the technical field of window cleaning machines, in particular to a window cleaning machine which is easy to lift. Background Art

[0002] Glass curtain walls are widely used in high-rise buildings. The circular window cleaning machine is an automatic cleaning device specially used for cleaning the glass curtain walls of high-rise buildings. It has the characteristics of high efficiency and safety. At the same time, machine cleaning can minimize the danger of manual operation.

[0003] A Chinese patent provides a window cleaning machine with publication number CN205251400U, which includes an upper cover, a lower cover, a motor and two sets of symmetrically arranged operating devices. The motor is arranged inside the upper cover and the lower cover, and a fan and an impeller are provided on the output end of the motor.

[0004] The above-mentioned device uses the combined action of the motor, fan and impeller to draw the sealed cavity formed by the sealing cover and the lower cover into a semi-vacuum state for wiping operation. The setting of the anti-slip operation device can increase the adsorption performance between the window cleaning machine and the glass, effectively prevent the window cleaning machine from falling from the glass, and enable the window cleaning machine to move more stably on the glass. However, when the window cleaning machine performs reciprocating cleaning on the corners, it needs to move back and forth, and its flexibility of use is poor. In addition, when the two cleaning discs are raised and lowered for scrubbing, they need to move back and forth, which greatly affects the cleaning efficiency. Utility Model Content

[0005] The purpose of the utility model is to provide a window cleaning machine that is easy to lift and lower, so as to solve the problems encountered in the use of existing devices.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a window cleaning machine that is easy to lift, comprising a circular window cleaning machine body, a handle being provided at the center of the top of the circular window cleaning machine body, negative pressure suction cups being provided on both sides of the bottom of the circular window cleaning machine body, rotating cleaning discs being rotatably mounted on the outer rings of the two negative pressure suction cups, and a lifting assembly being provided at the front end of the circular window cleaning machine body;

[0007] The lifting assembly has two electric telescopic rods, which are respectively installed at the center of the top end of the circular window cleaning machine body, and the front end of the push rod of the electric telescopic rod is fixedly installed with a connecting block, the front end of the connecting block is installed with a mounting plate through a mounting bolt, and a negative pressure suction cup 2 is provided at the center of the front part of the mounting plate, and pressure plates are fixedly connected to both sides of the mounting plate.

[0008] Preferably, the mounting plate is arranged in an "L" shape, and the bottom surface of the second negative pressure suction cup is flush with the bottom surface of the first negative pressure suction cup.

[0009] Preferably, a brushing motor is installed inside the circular window cleaning machine body, and the driving shaft of the brushing motor is connected to the two rotating brushing discs through a transmission wheel set.

[0010] Preferably, fixing bolt columns are movably installed at the upper and lower ends of the two pressure plates and at the corner positions on one side away from the second negative pressure suction cup, and scrubbing cotton plates are fixedly installed at the bottom ends of the four fixing bolt columns.

[0011] Preferably, a through groove that adaptably matches the second negative pressure suction cup is provided at the center position of the upper and lower ends of the scrubbing cotton plate, and the second negative pressure suction cup passes through the through groove, and the second negative pressure suction cup is slidably connected to the scrubbing cotton plate.

[0012] Preferably, an elastic tightening sleeve is provided around the outer ring of several fixing bolt columns, and the upper and lower ends of the elastic tightening sleeve are fitted with the upper and lower opposite surfaces of the pressure plate and the scrubbing cotton plate, and the bottom surface of the scrubbing cotton plate is flush with the bottom surface of the rotating scrubbing disc.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1) This easy-to-lift window cleaning machine, through the provided lifting assembly and the circular window cleaning machine body, can suck the glass at the appropriate position through two negative pressure suction cups during cleaning, and through the extension and retraction of the electric telescopic rod, the two rotating wiping discs can be directly raised and lowered at the appropriate position for cleaning, without the need for alternating on and off movement, which is conducive to improving cleaning efficiency and high flexibility of use;

[0015] 2) This easy-to-lift window cleaning machine uses an electric telescopic rod to cooperate with the scrubbing cotton board. Since the scrubbing cotton board is square in shape and its size matches the two cleaning discs, after it is sucked onto the appropriate position of the glass by the rotating wiping disc, the electric telescopic rod is extended and retracted to drive the mounting plate to move, so that the mounting plate can be easily pushed to the corner of the glass for scrubbing, thereby eliminating blind spots and improving the cleaning effect.
