[0027] See also Figure 1 and Figure 4 In one embodiment of the present application, a particle collecting device 10 is provided. The particle collecting device 10 comprises a housing 101, a flow guide tube 102 and a first filter element 103. The flow guide tube 102 is located inside the housing 101 for introducing gas into the housing 101, and the first filter element 103 is movably connected to the outer edge of the flow guide tube 102 for filtering the gas, and the movement of the first filter element 103 causes particles in the gas to fall to the bottom of the housing 101.

[0028] In the particle collection device 10 of the present embodiment, the gas containing particles can be introduced into the shell 101 through the guide tube 102. After the gas is introduced into the shell 101, the particles in the gas can be intercepted by the action of the first filter element 103, and then the particles on the first filter element 103 can be detached and dropped to the bottom of the shell 101 through the movement of the first filter element 103. This can reduce the amount of particles attached to the inner wall of the shell 101 and reduce the difficulty of cleaning the particle collection device 10.

[0029] It is understandable that the first filter element 103 can move in a manner of vibration, shaking, or reciprocating within a certain stroke, that is, the movement of the first filter element 103 can cause the particles on the first filter element 103 to fall to the bottom of the shell 101, thereby reducing the amount of particles attached to the inner wall of the shell 101 and reducing the difficulty of cleaning the particle collection device 10.

[0030] See also Figure 1 and Figure 2 In some embodiments, the particle collection device 10 further includes a connecting ring 104. The connecting ring 104 is sleeved on the outer edge of the flow guide tube 102, and the first filter element 103 is fixed on the connecting ring 104. By providing the connecting ring 104 and fixing the first filter element 103 on the connecting ring 104, the first filter element 103 can be driven to move by the movement of the connecting ring 104 on the outer edge of the flow guide tube 102, thereby causing the particles on the first filter element 103 to detach and fall to the bottom of the housing 101. It can be understood that by sleeved the connecting ring 104 on the outer edge of the flow guide tube 102, it is convenient to drive the first filter element 103 to move by the connecting ring 104, and it is also convenient to stably control the movement path of the first filter element 103.

[0031] In some embodiments, there are multiple first filter elements 103, and the multiple first filter elements 103 are spaced and distributed on the connecting ring 104. By providing multiple first filter elements 103, the filtering efficiency of particles can be improved, so that the particles in the gas can be fully intercepted by the multiple first filter elements 103, thereby improving the collection effect of the particle collection device 10.

[0032] It is understandable that in Figure 1 and Figure 2 In the corresponding particle collecting device 10, the number of the first filter elements 103 is three, and the three first filter elements 103 are evenly distributed on the connecting ring 104. It can also be understood that the number of the first filter elements 103 can also be appropriately selected according to actual needs, for example, the number of the first filter elements 103 can also be two, four, five, six, seven, etc.

[0033] In some embodiments, a connection hole 1031 is provided on the first filter element 103. The connection ring 104 passes through the connection hole 1031 to connect the first filter element 103. The connection hole 1031 is provided on the first filter element 103 to facilitate the stable connection between the first filter element 103 and the connection ring 104. Optionally, the connection hole 1031 is located above the first filter element 103, which facilitates the overall installation of the particle collection device 10 and can also reduce the shielding of the first filter element 103 by the connection ring 104, thereby giving full play to the filtering effect of the first filter element 103.

[0034] See also Figure 4 and Figure 5 In some embodiments, the particle collecting device 10 further includes a vibrating member 105. The vibrating member 105 is connected to the first filter element 103 to drive the first filter element 103 to vibrate. The first filter element 103 can be vibrated by the vibrating member 105, so that the particles on the first filter element 103 can fall to the bottom of the housing 101 more efficiently. Optionally, the vibrating member 105 is a vibrating piston.

[0035] It can be understood that the vibration member 105 is connected to the connecting ring 104, and further connected to the first filter member 103 through the connecting ring 104. Further, the particle collection device 10 also includes a connecting member 106, and the two ends of the connecting member 106 are respectively connected to the connecting ring 104 and the vibration member 105. Further, a mounting hole 1011 is provided above the shell 101, and the vibration member 105 is connected to the first filter member 103 through the mounting hole 1011. For example, the first filter member 103 is fixed to the connecting ring 104, one end of the connecting member 106 is connected to the connecting ring 104, and the other end of the connecting member 106 passes through the mounting hole 1011 and is connected to the vibration member 105.

[0036] Please refer again Figure 1 and Figure 2 In some embodiments, the particle capture device 10 further includes a second filter element 107. The second filter element 107 is located on the surface of the first filter element 103, and there is a gap between the second filter element 107 and the first filter element 103. The filtration particle size of the second filter element 107 is larger than the filtration particle size of the first filter element 103. The second filter element 107 cooperates with the first filter element 103, and the particles with larger particle sizes can be filtered through the second filter element 107, and the particles with smaller particle sizes can be filtered through the first filter element 103, thereby improving the interception effect of the filter element on particles. Optionally, the first filter element 103 has a screen structure, and the second filter element 107 has a screen structure, and the mesh size of the screen structure of the second filter element 107 is larger than the mesh size of the screen structure of the first filter element 103.

[0037] In some embodiments, the gap between the second filter element 107 and the first filter element 103 is 2 mm to 4 mm. Optionally, the gap between the second filter element 107 and the first filter element 103 can be, but is not limited to, 2 mm, 2.2 mm, 2.5 mm, 2.8 mm, 3 mm, 3.2 mm, 3.5 mm, 3.8 mm, 4 mm, etc.

[0038] Optionally, a mounting post 1032 is provided on the first filter element 103 for mounting the second filter element 107, and the diameter of the mounting post 1032 is 1 mm to 2 mm. The second filter element 107 can be stably mounted on the first filter element 103 through the mounting post 1032. Optionally, the mounting post 1032 can be a steel wire. Further optionally, the diameter of the mounting post 1032 can be, but is not limited to, 1 mm, 1.2 mm, 1.5 mm, 1.8 mm, 2 mm, etc.

[0039] See also Figure 1 and Figure 3 In some embodiments, the particle collection device 10 further includes a spiral guide plate 108. The spiral guide plate 108 is arranged around the outer edge of the guide tube 102 along the axial direction of the guide tube 102. A through hole 1081 is provided on the spiral guide plate 108. The first filter element 103 passes through the through hole 1081. There is a gap between the first filter element 103 and the hole wall of the through hole 1081. The arrangement of the spiral guide plate 108 can have a good backflow effect on the flow direction of the gas, thereby improving the particle collection effect of the particle collection device 10 on particles. The particles on the first filter element 103 can fall to the bottom of the housing 101 through the gap between the first filter element 103 and the hole wall of the through hole 1081. Optionally, the gap between the first filter element 103 and the hole wall of the through hole 1081 is ≤2mm. For example, the gap between the first filter element 103 and the hole wall of the through hole 1081 can be, but not limited to, 2mm, 1.8mm, 1.5mm, 1.2mm, etc.

[0040] In some embodiments, the outer edge of the spiral guide plate 108 abuts against the inner wall of the housing 101. Optionally, a sealing strip may be provided between the spiral guide plate 108 and the housing 101 to improve the sealing effect.

[0041] Please refer again Figure 4 and Figure 5 In some embodiments, the housing 101 is provided with an air inlet 1012 and an air outlet 1013. The air inlet 1012 is connected to the flow guide tube 102, and the air outlet 1013 is staggered with the pipe opening of the flow guide tube 102.

[0042] It is understandable that the housing 101 includes a top cover, and the air inlet 1012, the air outlet 1013 and the mounting hole 1011 are arranged on the top cover. The top cover is connected and sealed with the main body of the housing 101 by using threads and a sealing ring.

[0043] It is understood that when capturing particles in the gas, the gas with particles can enter the guide tube 102 through the air inlet 1012, and then the gas can be extracted through the vacuum pump connected to the air outlet 1013 to form a good gas circulation path. When it is necessary to make the particles on the filter element fall to the bottom of the shell 101, the vacuum pump is turned off, and the first filter element 103 is vibrated by the vibration element 105, so that the particles fall to the bottom of the shell 101. It is also understood that the guide tube 102 extends into the bottom near the shell 101, so that the gas can move upward from the bottom of the shell 101, thereby extending the movement path of the gas and improving the particle capture effect of the particle capture device 10 on the particles. It is also understood that the bottom of the shell 101 is provided with a receiving hole 1014, and the receiving hole 1014 is used to take out the particles. When it is necessary to take out the particles in the shell 101, the particles at the bottom of the shell 101 can be taken out through the receiving hole 1014.

[0044] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0045] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
