Description

Technical Field

[0001] This application relates to the technical field of dust removal robots, and particularly to a dust suction system. Background Art

[0002] In existing dust removal robots, their dust suction systems usually include complex outer shells, pipes, filters, and multiple components, which are fixed and connected to each other by mechanical means such as bolts and buckles. When these systems are integrated into the interior of a device (such as a robot), they often face problems such as low space utilization rate, complex disassembly and assembly, and inconvenient maintenance. For example, a stair and floor sweeping and mopping robot disclosed in Patent No. CN112493927B collects all dust in the vacuum cleaner. When the vacuum cleaner is full of dust inside, it is very inconvenient to disassemble it for replacement and cleaning. If the existing dust suction device is directly assembled on the robot, when internal parts of the dust suction device need to be replaced, such as the repair of a centrifugal fan or the replacement of a filter screen, the entire dust suction device together with the dust removal pipe needs to be disassembled, and the disassembly and repair difficulties are great. Utility Model Content

[0003] In order to facilitate the disassembly and repair of the dust removal device on the installation equipment, this application provides a dust suction system.

[0004] A dust suction system provided by this application adopts the following technical solutions:

[0005] A dust suction system includes a collection box, a dust suction connector, a filter cover, and a fan. The dust suction connector and the filter cover are both arranged on a moving device. The fan is installed on the filter cover. The collection box is magnetically connected to the filter cover through a magnetic part. The collection box is magnetically connected to the dust suction connector through a magnetic part. The fan is communicated with the filter cover. The filter cover is communicated with the collection box. The dust suction connector is communicated with the collection box. A filter element for preventing dust and impurities from entering its interior is arranged in the filter cover. The filter element is magnetically connected to the filter cover through a magnetic part.

[0006] By adopting the above technical solutions, after the fan is started, a negative pressure is formed inside the filter cover, the collection box, and the dust suction connector. The dust suction connector sucks in dust and discharges it into the collection box. When the collection box is full of dust, just pull out the collection box with force, and the collection box can be separated from the dust suction connector and the filter cover, which is convenient for handling the dust and impurities in the collection box. When the dust suction connector, the filter cover, and the fan need to be replaced, they can all be disassembled from the equipment separately without removing other components, which is convenient for disassembling and repairing the dust removal device on the installation equipment.

[0007] Optionally, the filter cover is arranged on the top of the collection box. Both the side of the collection box opposite to the filter cover are arranged as inclined planes. A first sealing groove is formed in the inclined plane of the collection box, and a second sealing groove is formed in the inclined plane of the filter cover. A first sealing ring is jointly arranged in the first sealing groove and the second sealing groove. A guiding surface is arranged on the inner peripheral wall of the first sealing groove. The inclined plane of the filter cover and the inclined plane of the collection box are magnetically connected through magnetic components.

[0008] By adopting the above technical solution, the docking surfaces of the collection box and the filter cover are arranged as inclined planes. When the insertion height of the collection box is higher than that of the filter cover, the two inclined planes play a guiding role, facilitating the alignment of the collection box with the filter cover. Moreover, the first sealing ring not only plays a sealing role. If the first sealing groove is not aligned with the first sealing ring, there will be a gap between the docking surfaces of the collection box and the filter cover. By using the cooperation of the first sealing groove, the second sealing groove and the first sealing ring, it is convenient to observe whether the collection box and the filter cover are aligned. And the guiding surface facilitates the first sealing ring to be smoothly inserted into the first sealing groove, reducing the wear of the first sealing ring during long-term repeated disassembly and assembly of the collection box.

[0009] Optionally, the dust suction connecting piece includes an extension pipe and a dust suction pipe. The dust suction pipe is bolted to the moving device. One end of the extension pipe is provided with a first connecting seat, and the other end is provided with a second connecting seat. One end of the dust suction pipe close to the extension pipe is provided with a third connecting seat. The first connecting seat is magnetically connected to the collection box through a magnetic component. The first connecting seat is located on one side of the collection box. The extension pipe is communicated with the collection box. The second connecting seat is magnetically connected to the third connecting seat. The dust suction pipe is communicated with the extension pipe.

[0010] Optionally, a first docking groove is formed in the first connecting seat, and a first docking block is arranged on the collection box. When the first docking block is inserted into the first docking groove, the air inlet of the collection box is directly opposite to the air outlet of the extension pipe.

[0011] By adopting the above technical solution, it is convenient for the collection box to quickly align with the extension pipe, avoiding the situation of air leakage caused by misalignment when the extension pipe is docked with the collection box.

[0012] Optionally, a second docking groove is formed in the second connecting seat, and a second docking block is arranged on the third connecting seat. When the second docking block is inserted into the second docking groove, the air inlet of the extension pipe is directly opposite to the air outlet of the dust suction pipe.

[0013] By adopting the above technical solution, it is convenient for the extension pipe to quickly align with the dust suction pipe, avoiding the situation of air leakage caused by misalignment when the extension pipe is docked with the dust suction pipe.

[0014] Optionally, a reinforcement plate is provided on the extension pipe, and the collection box is provided with an embedding groove. When the third connection seat is connected to the collection box, the peripheral surface of the extension pipe is exactly embedded in the embedding groove, and the reinforcement plate and the collection box are magnetically connected by a magnetic member.

[0015] By adopting the above technical solution, the setting of the embedding groove can reduce the occupied space of the dust removal system for the equipment, and at the same time play a guiding role. Cooperating with the first docking block and the first docking groove, it further ensures the alignment of the extension pipe and the collection box.

[0016] Optionally, the first connection seat and the collection box are hermetically connected by a second sealing ring, and both the second connection seat and the third connection seat are hermetically connected by a third sealing ring.

[0017] Optionally, fixed frames are provided on both sides of the filter cover. The fixed frames are bolted to the moving device. The collection box is located between the two fixed frames. Limiting blocks are provided on one side of the two fixed frames facing each other. When the collection box and the filter cover are in a connected state, the side wall of the collection box abuts against the limiting block on its same side.

[0018] By adopting the above technical solution, the fixed frame facilitates the installation of the filter cover on the equipment, and the limiting block can ensure that the collection box will not be displaced left and right when installing the collection box. Cooperating with the first docking block and the first docking groove, it further ensures the alignment of the collection box with the filter cover and the extension pipe.

[0019] Optionally, a positioning plate is provided on the filter cover, a positioning hole is opened on the positioning plate, a positioning column is provided on the extension pipe, and the positioning column passes through the positioning hole and is adapted to it.

[0020] By adopting the above technical solution, the cooperation of the positioning plate and the positioning column ensures the accurate relative position of the extension pipe and the filter cover, and can quickly determine the relative position of the extension pipe and the filter cover.

[0021] Optionally, the dust suction pipe is in an S-shaped tubular shape, and a hand-held groove is opened on one side of the collection box facing away from the extension pipe.

[0022] By adopting the above technical solution, the S-shaped tubular design can make the dust suction pipe avoid other components of the equipment, and the design of the hand-held groove facilitates the extraction of the collection box from the equipment.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. After the fan is started, a negative pressure is formed inside the filter cover, the collection box and the dust suction connector. The dust suction connector sucks in dust and discharges it into the collection box.
