Description

A rotary filter device for a sweeping robot

technical field

The utility model relates to the field of intelligent household appliances, in particular to a rotating filter screen device of a sweeping robot.

Background technique

The sweeping robot can automatically complete the floor cleaning work in the room with certain artificial intelligence. Generally, brushing and vacuuming are used to absorb the debris on the ground into its own garbage storage box, so as to complete the function of ground cleaning. Generally speaking, cleaning, vacuuming and mopping will be done. The garbage is sucked into the storage box through the suction cup. One or more layers of filter screen are generally set between the suction cup and the storage box. Because the high-pressure and high-speed airflow is strip-shaped, the filter screen cannot be completely covered. It is small and cannot be sucked away by high-speed airflow, so that more and more dust and dirt are accumulated on the edge of the filter screen. After the cleaning is completed, the cleaning robot needs to be disassembled to clean the filter screen.

SUMMARY OF THE INVENTION

In order to solve the defects referred to in the background art, dirty air is sucked from the ground by the suction module of the sweeping robot, and then passes through the strip nozzle to form a high-pressure and high-speed airflow, which is aimed at the rotating filter of the sweeping robot for dust removal, so as to reduce the filter screen. Accumulation speed, while reducing the process of frequent disassembly of the machine for cleaning. The utility model is realized through the following technical solutions.

A rotating filter screen device of a sweeping robot, the rotating filter screen device comprises a circular filter screen support and a filter screen, the filter screen support is rotatably connected with one side of a dust box, and the filter screen is pasted on one side of the filter screen support, A fan blade is arranged on the other side of the filter screen bracket. The shaft of the fan blade and the filter screen bracket are fixed by a plurality of connecting rods. There are sliding grooves on the side of the filter screen bracket. The slide slot of the bracket rotates along the circular opening.

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

Further, the fan blades are detachable.

Compared with the prior art, the beneficial effect of the present invention is that when the suction nozzle generates enough suction, the rotating filter screen device will rotate with the suction force, and the rotating filter screen can relieve the dust accumulated on the filter screen.

Detailed ways

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

As shown in Figures 1-5, a rotating filter screen device 20 of a cleaning robot includes a circular filter screen support 21 and a filter screen 22, and the filter screen support 21 is rotatably connected to one side of the dust box 6, The filter screen 21 is pasted on one side of the filter screen support, the other side of the filter screen support is provided with a fan blade 24, and the fan blade is set on the side outside the dust box. The shaft 23 of the fan blade and the filter screen bracket are fixed by a plurality of connecting rods 25. There are sliding grooves 26 on the side of the filter screen bracket. The shaped opening turns. A plurality of balls 27 are further included in the sliding groove, so that the rotary screen device can be easily rotated.

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

As shown in Figure 6, Figure 6 is the position of the device in the structure of the sweeping robot. In the embodiment of the present invention, the vacuuming principle of the sweeping robot is mainly to move the sweeping robot in the room through the rotation of the wheels, and the battery box The battery installed inside is the circuit board, the motor that drives the wheels, and the motor that drives the roller brush, so that when the side brush rotates, the dust and dirt are swept to the air inlet, and the roller brush cooperates with the suction of the air inlet to remove the dust and dirt from the air inlet. Inhalation, enter the dust box through the channel, and the sweeping robot also includes a dust box 6; the air inlet is communicated with the air inlet of the dust box 6; the air outlet (not marked) of the dust box 6 is communicated with the connecting pipe; the outlet of the dust box 6 A rotating filter screen device is arranged between the air outlet (not shown) and the connecting pipe of the fan device.

In the embodiment of the present invention, a fan device 7 connected to the dust box 6 is further included. The fan device includes a fan 8, an air inlet 13 and an air outlet 12 communicated with the fan, and a connecting pipe connecting the air inlet 13 and the air outlet 12. 11. The fan 8 is located in the connecting pipe 11.

The air inlet 13 passes through the connecting plate of the same size as the dust box 6. When the connecting plate is connected with the dust box 6, a cavity that can accommodate the rotating filter screen device is generated, the fan device 7 and the dust box 6 are fixed together, and the fan of the rotating filter screen is formed. The leaf device can work in the cavity, and the side with the fan blade is located on the side of the connecting plate. In the present invention, the connecting plate preferably has a concave surface, and the concave surface is connected to the dust box 6 . The air inlet 13 includes a suction nozzle arranged on the air inlet, and the suction nozzle is in the shape of a strip or an oval or an oblong structure. The shape of the suction nozzle matches the strip air flow generated by the fan, which can increase the suction force and act on the fan blades on the rotating filter device to make the device rotate.

The working principle of the utility model is that after the air enters the main air inlet, it enters the interior of the dust box 6 from the air inlet of the dust box 6, then enters the filter screen from the air outlet of the dust box 6, and then enters the connecting pipe 11, and enter the fan 7 from the air outlet, and finally discharge. After using for a period of time, some dust accumulates on the edge of the air outlet on the filter screen. The purpose of this utility model is to use the rotating filter screen device. During the rotation process of the filter screen, it not only increases the difficulty of dust accumulation on the filter screen, but also increases the difficulty of dust accumulation on the filter screen when the filter screen rotates. Under the action of the strip air flow of the fan, the dust that cannot pass through the filter screen rolls in the dust box and settles at the bottom of the filter box. On the other hand, the device can complete the rotation without additional power drive, which is convenient and practical. The fan blade is on the other side of the dust box, which is not easy to be polluted by the dust in the dust box, and can continue to work.

The above are only preferred embodiments of the present invention, and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
