Generally, the cleaning, dust collecting and floor wiping work is completed. Inhale the receiver with rubbish through the sucking disc, generally set up one deck or multilayer filter screen between sucking disc and the receiver, because produce the high-speed air current of high pressure for the bar, can't cover the filter screen completely, lead to when using, the filter screen edge is little because of the air current, can't suck away through high-speed air current for filter screen edge accumulation more and more dust and foul clean the completion back, need dismantle the robot of sweeping the floor and wash the filter screen.

Disclosure of Invention

In order to solve the defects in the background technology, dirty air is sucked from the ground by the suction module of the sweeping robot and then passes through the strip-shaped nozzles to form high-pressure high-speed airflow which is directed at a rotary filter screen of the sweeping robot to remove dust, so that the accumulation speed of the filter screen is reduced, and the process of frequently disassembling and cleaning the machine is reduced. The utility model discloses a realize through following technical scheme.

The utility model provides a rotary filter unit of robot sweeps floor, rotary filter unit includes circular shape filter screen support and filter screen, the one side swivelling joint of filter screen support and dirt box, and the filter screen pastes on one side of filter screen support, and filter screen support's another side sets up the flabellum, and the axle of flabellum is fixed through a plurality of connecting rods with filter screen support, and filter screen support's side has the sliding tray, and the sliding tray is installed at the circular opening part of dirt box, makes filter screen support's sliding tray rotate along circular opening.

Further, the sliding groove further comprises a plurality of balls.

Further, the fan blades can be detached.

Compared with the prior art, the beneficial effects of the utility model are that: when the suction nozzle generates sufficient suction, the rotary screen assembly rotates with the suction, and the rotating screen relieves dust that accumulates on the screen.

Detailed Description

The embodiments of the invention will be described in detail below with reference to the drawings, but the invention can be implemented in many different ways as defined and covered by the claims.

As shown in fig. 1-5, the rotary filter screen device 20 of the sweeping robot includes a circular filter screen bracket 21 and a circular filter screen 22, the filter screen bracket 21 is rotatably connected to one side of the dust box 6, the filter screen 21 is adhered to one side of the filter screen bracket, and the other side of the filter screen bracket is provided with a fan blade 24, which is arranged on one side outside the dust box. The shaft 23 of the fan blade is fixed with the filter screen bracket through a plurality of connecting rods 25, the side of the filter screen bracket is provided with a sliding groove 26, and the sliding groove is arranged at the circular opening of the dust box, so that the sliding groove of the filter screen bracket rotates along the circular opening. The slide groove further includes a plurality of balls 27 therein to facilitate rotation of the rotary screen assembly.

In the embodiment of the present invention, the fan blade 24 is fixed on the shaft 23, and can be detached for cleaning.

As shown in fig. 6, fig. 6 shows the position of the device in the sweeping robot structure, in the embodiment of the present invention, the dust collection principle of the sweeping robot mainly makes the sweeping robot move in a room through the rotation of the wheels, the battery installed in the battery box is the circuit board, the motor driving the wheels, and the motor driving the rolling brush rotate, when the side brush rotates, the side brush cleans dust and dirt to the air inlet, the rolling brush sucks the dust and dirt from the air inlet by matching with the suction force of the air inlet, and enters the dust box through the channel, and the sweeping robot further includes the dust box 6; the air inlet is communicated with the air inlet of the dust box 6; an air outlet (not shown) of the dust box 6 is communicated with the connecting pipe; a rotary filter screen device is arranged between an air outlet (not shown) of the dust box 6 and a connecting pipe of the fan device.

The embodiment of the utility model provides an in, still include the fan device 7 of being connected with dirt box 6, the fan device includes fan 8, with air intake 13 and air outlet 12 of fan UNICOM to and the connecting pipe 11 of UNICOM's air intake 13 and air outlet 12, fan 8 is located connecting pipe 11.

Air intake 13 is through the connecting plate the same with the size of dirt box 6, and the connecting plate produces the appearance chamber that can hold rotary filter device when being connected with dirt box 6, is in the same place fan device 7 is fixed with dirt box 6, and rotary filter's flabellum device can be in appearance intracavity work, and the one side that has the flabellum is located connecting plate one side the utility model discloses well preferred connecting plate has a concave surface, and the concave surface is connected with dirt box 6. The air inlet 13 comprises a suction nozzle arranged on the air inlet, and the suction nozzle is of a strip-shaped or oval or long round structure. The shape of the suction nozzle is matched with the strip-shaped airflow generated by the fan, so that the suction force can be increased, and the suction nozzle acts on fan blades on the rotary filter screen device to rotate the device.

The utility model discloses an operating principle is, and the air current gets into the back from main air intake, again from the inside that the 6 air intakes of the dirt box of dirt box 6 got into dirt box 6, again from the air outlet entering filter screen of dirt box 6, reentrant connecting pipe 11 to get into fan 7, discharge at last from the exhaust vent. After using a period, some dusts of wind gap edge accumulation on the filter screen, the utility model discloses a through rotatory filter unit, at the rotatory in-process of filter screen, not only increased the accumulational degree of difficulty of dust on the filter screen, under the bar air current effect of fan when the filter screen is rotatory moreover, the dust that can't pass through the filter screen deposits in the filter box bottom after rolling in the dirt box. On the other hand, the device can complete rotation without additional power drive, and is convenient and practical. The fan blades are arranged on the other surface of the dust box, are not easily polluted by dust in the dust box, and can continuously work.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
