[0028] The following Figures 1 to 5 describes a grinding robot with a swing dust cleaning mechanism and its application, including a dust collection box 1, a blower 2, a dust filter element group 3, and a swing dust sweeping assembly 4; the dust collection box 1 is provided with an air inlet 101, an air outlet 102, and an air outlet 103, the dust filter element group 3 is arranged at the air inlet 101, the blower 2 is arranged at the air outlet 103, the swing dust sweeping assembly 4 is arranged on one side of the dust filter element group 3, and the swing end of the swing dust sweeping assembly 4 swings left and right relative to the dust collection box 1, so that the swing end of the swing dust sweeping assembly 4 sweeps the dust filter element group 3.

[0029] The specific working process is as follows. The blower 2 is started, air is drawn from the dust collection box 1 and exhausted from the air outlet 103, so as to form a vacuum in the dust collection box 1 for suction. Dust enters the dust collection box 1 from the air inlet 101, and the dust is filtered by the dust filter element group 3. Finally, the air without dust is discharged from the air outlet 103, and the dust particles adhere to the dust filter element group 3. The dust pile accumulated on the dust filter element group 3 will fall downward under the action of gravity and be discharged from the air outlet 102 to the external collection bag. However, after long-term use, there will be a problem that the dust accumulates on the dust filter element group 3 and does not fall. Therefore, the swing dust sweeping assembly 4 is provided. The swing end of the swing dust sweeping assembly 4 sweeps the dust filter element group 3, and the filter chips of the dust filter element group 3 are vibrated by the sweeping, so that the accumulated dust falls, thereby solving the problems that the dust accumulates on the dust filter element group 3, the dust does not fall and cannot be collected, and the dust filter element group 3 is blocked, resulting in a poor filtering effect.

[0030] In this embodiment, the swing dust sweeping assembly 4 includes a driving assembly 41, a guiding assembly 42, and a dust sweeping swing member 43; the guiding assembly 42 is fixedly connected to the dust collection box 1, and the guiding assembly 42 is arranged on one side of the dust filter element group 3. The dust sweeping swing member 43 is slidably arranged on the guiding assembly 42, and the driving end of the driving assembly 41 is connected to the dust sweeping swing member 43 to drive the dust sweeping swing member 43 to make a reciprocating sliding motion along the guiding assembly 42.

[0031] Specifically, in this embodiment, the driving end of the driving component 41 drives the dust-sweeping swinging member 43 to reciprocate along the guiding component 42. During the reciprocating movement of the dust-sweeping swinging member 43, the dust-sweeping swinging member 43 will clean the dust filter element group 3, causing the filter chips of the dust filter element group 3 to vibrate, and the accumulated dust to fall off, effectively reducing the amount of dust accumulated on the dust filter element group 3.

[0032] In this embodiment, the driving component 41 includes a driving motor 411, a crank rocker 412, and a driving connecting rod 413; one end of the crank rocker 412 is fixedly arranged at the output end of the driving motor 411, the other end of the crank rocker 412 is rotatably connected to one end of the driving connecting rod 413, and the other end of the driving connecting rod 413 is rotatably connected to the dust-sweeping swinging member 43.

[0033] Specifically, in this embodiment, through the continuous operation of the driving motor 411, the crank rocker 412 is driven to rotate. By using the connecting rod connection between the crank rocker 412 and the driving connecting rod 413, the dust-sweeping swinging member 43 is driven to make a linear reciprocating motion along the guiding component 42, thereby realizing the cleaning operation of the dust filter element group 3. The structural connection is compact and simple, and can effectively save costs.

[0034] In this embodiment, the guiding component 42 is at least two guiding rods 421, and both ends of the dust-sweeping swinging member 43 are respectively sleeved on the outer periphery of the guiding rods 421.

[0035] Specifically, in this embodiment, both ends of the dust-sweeping swinging member 43 are respectively sleeved on the outer periphery of the guiding rods 421. By at least two guiding rods 421, it is ensured that the dust-sweeping swinging member 43 will not swing on a horizontal plane, and the guiding rods 421 guide the moving direction of the dust-sweeping swinging member 43 to avoid problems such as the deviation of the dust-sweeping swinging member 43.

[0036] In this embodiment, the dust-sweeping swinging member 43 includes a sliding portion 431 and a dust-sweeping portion 432. There are several dust-sweeping portions 432, and the dust-sweeping portions 432 are arranged side by side on one side of the sliding portion 431. The dust-sweeping portions 432 protrude along the sliding portion 431 in the direction of the dust filter element group 3, and the sliding portion 431 is limited and slidably connected to the guiding component 42.

[0037] Specifically, in this embodiment, the sliding portion 431 is slidably connected to the guiding component 42, and the dust-sweeping portion 432 is protrudingly arranged on one side of the sliding portion 431. During the sliding movement of the sliding portion 431, the dust-sweeping portion 432 collides with the dust filter element group 3, and the dust-sweeping portion 432 will sweep the filter sheets in the dust filter element group 3, so that the dust falls off.

[0038] In this embodiment, the dust collection box 1 is provided with a dust collection chamber 11, a transition chamber 12 and an air extraction chamber 13. The dust collection chamber 11 and the air extraction chamber 13 are relatively sealed. An air inlet 104 is provided and communicated between the dust collection chamber 11 and the transition chamber 12. An air extraction port 105 is provided and communicated between the transition chamber 12 and the air extraction chamber 13. The dust filter element group 3 is arranged in the dust collection chamber 11 and is located at the air inlet 104. The fan 2 is arranged in the air extraction chamber 13 and is located at the air extraction port 105. The dust inlet 101 and the dust outlet 102 are respectively communicated with the dust collection chamber 11, and the air outlet 103 is communicated with the air extraction chamber 13.

[0039] Specifically, in this embodiment, the fan 2 is installed in the air extraction chamber 13. The fan 2 extracts air from the transition chamber 12 through the air extraction port 105 and sends the air out through the air outlet 103, so that the transition chamber 12 is in a negative pressure state. Since the fan 2 causes the transition chamber 12 to generate negative pressure and drives the air flow, the external dusty air will enter the dust collection chamber 11 from the dust inlet 101. The transition chamber 12 sucks the air in the dust collection chamber 11 through the air inlet 104. However, the air in the dust collection chamber 11 will be filtered by the dust filter element group 3 before entering the transition chamber 12. The dust is filtered on the dust filter element group 3, and the dust-free air enters the transition chamber 12, and then is discharged from the air outlet 103 through the fan 2. It is realized that the dust in the dusty air is filtered in the dust collection box 1 and collected from the dust outlet 102, avoiding environmental pollution caused by dust emission and problems such as affecting the lubrication of mechanical parts and the physical health of the human body.

[0040] In this embodiment, at least two air inlets 104 are provided, and a set of the dust filter element group 3 is respectively arranged at each air inlet 104.

[0041] Specifically, in this embodiment, by filtering the dust through multiple air inlets 104 in cooperation with multiple sets of dust filter element groups 3, the filtering effect and efficiency can be effectively improved, so that the dust filtering is more thorough, and problems such as a sharp drop in the filtering effect after a single dust filter element group 3 is blocked by dust can be avoided.

[0042] In this embodiment, the dust inlet 101 and the air outlet 103 are respectively arranged at both ends of the top of the dust collection box 1, and the dust outlet 102 is arranged at the bottom of the dust collection box 1.

[0043] Specifically, in this embodiment, when the fan 2 starts to draw air, a vacuum is formed in the dust collection box 1 for suction, so that dust enters the dust collection box 1 from the dust inlet 101. Under the action of the dust filter element group 3, the dust is filtered. Finally, the air without dust is discharged from the air outlet 103, while the dust particles adhere to the dust filter element group 3. The dust pile accumulated on the dust filter element group 3 will fall downward under the action of gravity and be discharged from the dust outlet 102 into an external collection bag. The dust inlet 101 and the air outlet 103 are respectively arranged at both ends of the top of the dust collection box 1, and the dust outlet 102 is arranged at the bottom of the dust collection box 1, which can effectively improve the dust filtering effect and the collection effect.

[0044] This application also proposes a grinding robot, which includes a mobile robot 200, a grinding disc 300 and the swing-type dust cleaning mechanism 100. The grinding disc is provided with a dust suction pipe 400 connected to the dust inlet 101, and a dust collection bag 500 is installed at the dust outlet 102.

[0045] Specifically, in this embodiment, when the mobile robot 200 of the grinding robot drives the grinding disc 300 to work, dust will be raised. The air with dust is sucked into the dust collection box 1 through the dust suction pipe 400. After being filtered by the swing-type dust cleaning mechanism, the dust accumulates and falls from the dust outlet 102 into the dust collection bag 500, collecting the dust generated by grinding, effectively avoiding environmental pollution caused by dust, and problems such as affecting the lubrication of mechanical parts and the physical health of the human body.
