[0052] Please refer to Figure 1 , this application provides a laser processing system 100, which includes a laser processing device 10 and a purifier 50.

[0053] Among them, the laser processing device 10 can specifically be a laser engraving machine or a laser cutting machine, etc. This application does not limit the type of the laser processing device 10, as long as it is a device that uses laser as a medium to process the workpiece to be processed. Further, the laser processing device 10 can include a machine body 11 and a laser head 13. The machine body 11 can be provided with a processing chamber 111, an air inlet 112 and an exhaust port 113 communicating with the processing chamber 111. The laser head 30 can be disposed in the processing chamber 111 to emit laser to perform laser processing on the workpiece to be processed placed in the processing chamber 111. In addition, the laser processing device 10 can also include a fan disposed on the machine body 11 to drive the external air flow to enter from the air inlet 112 and then be discharged from the exhaust port 113. Among them, the fan can be disposed in the processing chamber 111, and of course, it can also be disposed in the air inlet 112 or the exhaust port 113.

[0054] The purifier 50 can be used to purify the processing exhaust gas of the laser processing device 10. Specifically, the purifier 50 can be arranged outside the machine body 11 to reduce the volume of the machine body 11. At this time, the air inlet 512 of the purifier can be communicated with the exhaust port 113. Moreover, the laser processing system 100 can further include a connecting pipe 70. One end of the connecting pipe 70 can be communicated with the exhaust port 113, and the other end can be communicated with the purifier 50. Further, in order to facilitate the separate transportation and storage of the purifier 50 and the machine body 11, in an embodiment, the connecting pipe 70 and the machine body 11 and the purifier 50 can be detachably connected. Further, in order to simplify the disassembly and assembly process, the detachable connection manner of the connecting pipe 70 with the machine body 11 and the purifier 50 can be snap connection or magnetic connection, etc. In addition, in order to facilitate the adaptation of the connecting pipe 70 to the layout in various places, in an embodiment, the connecting pipe 70 can be a flexible pipe. Of course, in some embodiments, the purifier 50 can also be directly arranged in the exhaust port 113. Or, in some embodiments, the purifier 50 can also be arranged in the processing chamber 111. At this time, the air outlet 513 of the purifier 50 is communicated with the exhaust port 113.

[0055] Next, the structure of the purifier 50 will be explained and described:

[0056] Please refer to Figures 2 to 4 , in an embodiment of the present application, the purifier 50 includes a housing 51, a filter element assembly 53, and a cyclone separator 57. The housing 51 is provided with an air duct 511, an air inlet 512 and an air outlet 513 communicating with the air duct 511; the filter element assembly 53 is arranged in the air duct 511 and is located between the air inlet 512 and the air outlet 513. The filter element assembly 53 includes at least one filter element 534; the cyclone separator 57 is arranged in the air duct 511 and is located between the air inlet 512 and the air outlet 513. The cyclone separator 57 is located upstream of at least one filter element 534.

[0057] The housing 51 can form a path for the airflow to flow on the purifier 50 through the air inlet 512, the air duct 511, and the air outlet 513. Among them, the air inlet 512 can be directly connected to the exhaust port 113 on the body 10 introduced above. Of course, it can also be connected to the end of the connecting pipe 70 far from the exhaust port 113 introduced above. Or when the purifier 50 is directly disposed in the exhaust port 113 or the processing chamber 111 of the body 11, the air inlet 512 can also be directly connected to the processing chamber 111. In addition, the flow of the airflow on the purifier 50 can be powered by the first fan provided on the body 10 introduced above. Of course, it can also be that, as introduced below, the purifier 50 further includes a second fan 59 to more effectively drive the airflow. In addition, when the purifier 50 is in a normal use state and the ground is used as a reference, the air duct 511 in the housing 51 can be arranged to extend in the vertical direction. In other words, it can also be said that the air passing direction of the air duct 511 is from top to bottom or from bottom to top. Of course, in other embodiments, the air duct 511 in the housing 51 can also be arranged to extend in the horizontal direction. The air inlet 512 and the air outlet 513 can be respectively arranged at both ends of the housing 51 along the extension direction of the air duct 511, and can be located on the same side of the housing 51, or adjacent sides, or opposite sides. The present application does not limit the positions and shapes of the air inlet 512 and the air outlet 513. In addition, the projection of the housing 51 in the vertical direction can be a square or a rectangle, so that its shape is relatively regular to improve the convenience of its processing and manufacturing. Herein, the "square or rectangle" includes the case where the corners are not chamfered, and also includes the case where the boundary is rounded or beveled. Of course, in other embodiments, the projection of the housing 51 in the vertical direction can also be a circle or other shapes, and the present application does not limit this.

[0058] The filter element 534 can be used to filter the components to be filtered in the processing exhaust gas generated by the laser processing device 10. Among them, the components to be filtered can include particulate matter, harmful gases, or odors, etc. In addition, the number of filter elements 534 can be one, and of course, it can also be two or more. Moreover, when the number of filter elements 534 is two or more, the types of the respective filter elements 534 are at least partially different, and of course, they can also be all the same. In addition, the filter element 534 can be a cube or a cuboid to make it more regular and improve the convenience of its processing and manufacturing. Herein, the "cube or cuboid" includes the case where the corners are not chamfered, and also includes the case where the boundary is rounded or beveled. Of course, in other embodiments, the filter element 534 can also be a cylinder or other shapes, and the present application does not limit this. In addition, in order to improve the compactness of the distribution and reduce the overall volume of the purifier 50, in one embodiment, in the air passing direction of the air duct 511, the projected shapes of the casing 51, the air duct 511, and the filter element 534 can be set to be the same.

[0059] The cyclone separator 57 can perform high-speed centrifugal separation and collection on the particulate matter mixed in the air flow. Among them, when the number of filter elements 534 is one as introduced above, the cyclone separator 57 can be located upstream of the filter element 534. When the number of filter elements 534 is two or more as introduced above, the cyclone separator 57 can be located upstream of all the filter elements 534, and of course, it can also be located between two adjacent filter elements 534 to be only located upstream of some of the filter elements 534. In addition, the number of cyclone separators 57 can be set to one, and of course, it can also be provided with two or more. Moreover, when the number of cyclone separators 57 is two or more, the at least two cyclone separators 57 can be connected in series, in parallel, or in a hybrid connection including series and parallel.

[0060] The purifier 50 of the technical solution of the present application adds a cyclone separator 57 in the air duct 511 and arranges the cyclone separator 57 upstream of at least one filter element 534, so that the cyclone separator 57 can perform preliminary separation on the particulate matter mixed in the processing exhaust gas upstream of the filter element 534. In this way, the filtration burden downstream of the cyclone separator 57 can be reduced, which is conducive to extending the service life of the filter element 534 and reducing the replacement frequency of the filter element 534 to reduce the use cost. In addition, by adding the cyclone separator 57, the filtration ability of the purifier 50 for the processing exhaust gas can also be improved, and thus the filtration effect of the purifier 50 on the processing exhaust gas can be improved.

[0061] Please refer to Figure 2 and Figure 3In one embodiment of the present application, the air duct 511 is extended in the up-down direction, the air inlet 512 is provided at the upper end of the casing 51 , and the air outlet 513 is provided at the lower end of the casing 51 .

[0062] In this embodiment, the housing 51 can be extended in the vertical direction accordingly, which can improve the utilization of the space in the vertical direction, thereby helping to reduce the floor space occupied by the purifier 50. Furthermore, the air inlet 512 and the air outlet 513 are respectively arranged at the upper end and the lower end, thereby realizing the wind direction from top to bottom, that is, the airflow flows from top to bottom, so that the particles to be filtered in the airflow do not need to overcome gravity, which is conducive to improving the driving ability of the airflow on them.

[0063] Please refer to Figures 2 to 4 In one embodiment of the present application, the cyclone separator 57 is located in the wind direction of the air duct 511 (eg Figure 2 The cyclone separator 57 further comprises a cyclone side wall 57d connecting the first surface 57a and the second surface 57b; the cyclone side wall 57d is provided with a cyclone inlet 57e, and the second surface 57b is provided with a cyclone outlet 57c.

[0064] When the wind direction of the air duct 511 is from top to bottom as described above, the first surface 57a of the cyclone separator 57 can be the upper surface of the cyclone separator 57, the second surface 57b can be the lower surface of the cyclone separator 57, and the cyclone side wall 57d can be the side surface of the cyclone separator 57.

[0065] In this embodiment, the cyclone inlet 57e is arranged on the cyclone side wall 57d, so as to facilitate the cyclone separator 57 to enter the wind tangentially in the circumferential direction, better guide the airflow to rotate in the cyclone separator 57 and increase the flow rate, which is conducive to improving the separation effect of the cyclone separator 57 on the particulate matter mixed in the airflow. At the same time, with the cyclone outlet 57c arranged on the second surface 57b, the connecting pipe 70 and the housing 51 introduced above can be arranged at an angle, which is conducive to improving the compactness of the arrangement of the two, and conveniently realizing the air duct 511 extended in the up and down direction as introduced above. Of course, it should be noted that the present application is not limited to this. In other embodiments, the cyclone outlet 57c can also be arranged on the first surface 57a. At this time, the wind direction of the air duct 511 can be from bottom to top. Alternatively, the cyclone outlet 57c can also be arranged on the cyclone side wall 57d, and at this time, the air duct 511 can be extended in the horizontal direction.

[0066] Please refer to Figures 2 to 4, in an embodiment of the present application, the purifier 50 further includes a fan 59, and the fan 59 in the purifier 50 can be defined as the second fan 59; the second fan 59 is disposed in the air duct 511 and is located downstream of the filter element assembly 53 and the cyclone separator 57; the second fan 59 includes a first wall surface 591 and a fan side wall 593, the first wall surface 591 and the second surface 57b are disposed opposite to each other, and the second fan side wall 593 is connected to the first wall surface 591; the first wall surface 591 is provided with a fan inlet 591a, and the fan side wall 593 is provided with a fan outlet 593a.

[0067] When the air flow direction in the air duct 511 is from top to bottom as introduced above, the second fan 59 is located at the lowermost end compared with the filter element assembly 53 and the cyclone separator 57. The first wall surface 591 of the second fan 59 can be the upper surface of the second fan 59, and the fan side wall 593 can be the side surface of the second fan 59.

[0068] In this embodiment, setting the second fan 59 can improve the driving force of the air flow, and thus improve the driving effect of the air flow. And setting the second fan 59 downstream of the filter element assembly 53 and the cyclone separator 57 can enable the air flow to pass through the purification of the front cyclone separator 57 and the filter element assembly 53 and then pass through the second fan 59. In this way, the air flow flowing into the second fan 59 is relatively pure, which can avoid particulate matter or water vapor in the air flow from entering the second fan 59, and thus is beneficial to improving the service life of the second fan 59. Further, setting the fan inlet 591a on the first wall surface 591 can make it relatively opposite to the cyclone outlet 57c of the cyclone separator 57, and thus facilitate the regular extension of the air duct 511 in the up and down directions to improve the convenience of its manufacture. At the same time, it also facilitates the regular and compact arrangement of the filter element assembly 53, the cyclone separator 57 and the second fan 59 in the air duct 511 in the up and down directions to improve the convenience of its arrangement and reduce the overall volume of the purifier 50. And setting the fan outlet 593a on the fan side wall 593 can make the lower surface of the second fan 59 and the housing 51 do not need to be provided with an air passing space, and thus is beneficial to further improving the compactness of the distribution between the second fan 59 and the housing 51. At the same time, it can also avoid the ground from hindering the exhaust, and facilitate the smooth discharge of the gas from the side of the purifier 50.

[0069] Please refer to Figure 2 and Figure 4 , in an embodiment of the present application, the air inlet 512 and the air outlet 513 are located on the same side of the housing 51, the cyclone inlet 57e is correspondingly arranged corresponding to the air inlet 512, and the fan outlet 593a is correspondingly arranged corresponding to the air outlet 513.

[0070] When the air flow direction in the air duct 511 is from top to bottom as introduced above, the air inlet 512 and the air outlet 513 can be located on the left side of the housing 51, or on the right side of the housing 51, etc. The cyclone inlet 57e and the air inlet 512 can be directly connected, or can be connected through a part of the air duct 511, or can be connected through a duct. Similarly, the air outlet 513 of the fan outlet 593a can also be directly connected, or can be connected through a part of the air duct 511, or can be connected through a duct.

[0071] In this embodiment, the air inlet 512 and the air outlet 513 are arranged on the same side of the housing 51, so that both the air inlet side and the air outlet side of the purifier 50 can face the body 11 of the laser processing device 10, so as to make better use of the space between the purifier 50 and the body 10 and avoid the exhaust gas of the purifier 50 from affecting surrounding objects or people.

[0072] Please refer to Figure 3 , in an embodiment of the present application, the housing 51 is further provided with an installation opening 514 communicating with the air duct 511, and the installation opening 514 is configured to allow the filter element assembly 53 and the cyclone separator 57 to pass through, so as to be detachably installed in the air duct 511.

[0073] When the air inlet 512 and the air outlet 513 are located on the left side or the right side of the housing 51 as introduced above, the installation opening 514 can be located on the front side of the housing 51 and can be extended and opened along the extending direction of the air duct 511, that is, the up and down direction.

[0074] In this embodiment, by providing the installation opening 514, it is convenient to disassemble and assemble the cyclone separator 57 and the filter element 534. Among them, in order to simplify the disassembly and assembly process of the cyclone separator 57 and the filter element 534, a plurality of insertion slots 517 arranged side by side in the vertical direction can be provided on the left and right sides of the housing 51 in the air duct 511 for the cyclone separator 57 and the filter element 534 to be movably inserted into the corresponding insertion slots 517 through the installation opening 514. Among them, the insertion slot 517 can extend in the front-rear direction to the installation opening 514, or it can also be not extended to the installation opening 514 and be arranged at an interval from the installation opening 514, ensuring that the installation opening 514 can correspond to the insertion slot 517, so that when the filter element 534 is installed in the air duct 511 through the installation opening 514, it can be inserted and installed into the corresponding insertion slot 517. Further, in order to facilitate the gripping and disassembly of the cyclone separator 57, a handle 579 can be provided on one side of the cyclone separator 57 close to the installation opening 514. Similarly, in order to facilitate the gripping and disassembly of the filter element 534, a handle 579 can be provided on one side of the filter element 534 close to the installation opening 514. In addition, it should be noted that in other embodiments, the cyclone separator 57 and the filter element 534 can also be detachably connected to the housing 51 by snap connection or magnetic connection.

[0075] The extension direction of the air duct 511 of the housing 51, as well as the overall arrangement direction and installation method of the filter element assembly 53 and the cyclone separator 57, have been introduced above. Next, the detailed structures of the filter element assembly 53 and the cyclone separator 57 in the housing 51 will be explained and described respectively:

[0076] Please refer to Figure 2 and Figure 4 , in an embodiment of the present application, the filter element assembly 53 includes a front filter element component 531 and a rear filter element component 533 arranged in sequence along the air passing direction of the air duct 511. Both the front filter element component 531 and the rear filter element component 533 include at least one filter element 534, and the filter holes of the filter elements 534 in the front filter element component 531 are larger than the filter holes of the filter elements 534 in the rear filter element component 533;

[0077] The front filter element component 531, that is, the filter element 534 relatively closer to the air inlet 512, and the rear filter element component 533 is the filter element 534 relatively closer to the air outlet 513.

[0078] In this embodiment, at least two filter elements 534 form a front filter element component 531 and a rear filter element component 533, and the filter holes of the front filter element component 531 are larger than those of the rear filter element component 533. At this time, when the processed exhaust gas enters the air duct 511 from the air inlet 512 of the machine shell 51, it can first pass through the front filter element component 531 with relatively larger filter holes to perform prior filtration on relatively large particulate matters, and then pass through the rear filter element component 533 with relatively smaller filter holes to perform secondary filtration on relatively small particulate matters, harmful gases or peculiar smells, etc., thereby effectively filtering various components to be filtered in the processed exhaust gas by the purifier 50 to improve the filtering effect of the purifier 50. At the same time, through the hierarchical filtration of prior filtration and secondary filtration, the rear filter element component 533 is not easily contacted with relatively large particles, thereby reducing the possibility of blockage of the filter element 534 and further improving the service life of the filter element 534. At this time, since the front filter element component 531 has relatively large filter holes, the cyclone separator 57 can be located upstream of the front filter element component 531, or can also be located between the front filter element component 531 and the rear filter element component 533.

[0079] Please refer to Figure 4 , in an embodiment of the present application, the filter element 534 in the front filter element component 531 can be at least one of a primary filter element 531a and a medium - efficiency filter element 531b. That is, the front filter element component 531 can only include the primary filter element 531a, can only include the medium - efficiency filter element 531b, or can also include both the primary filter element 531a and the medium - efficiency filter element 531b. Moreover, the number of the primary filter elements 531a can be one, and of course, can also be two or more. Similarly, the number of the medium - efficiency filter elements 531b can be one, and of course, can also be two or more.

[0080] In this embodiment, the primary filter element 531a can play a good filtering role for relatively large particulate matters (such as dust, pollen or hair, etc.), and the medium - efficiency filter element 531b can play a good filtering role for relatively small particulate matters (such as dust, smoke, etc.), thereby effectively intercepting and filtering the particulate matters initially.

[0081] Please refer to Figure 4, in an embodiment of the present application, the filter element 534 in the rear filter element component 533 may be at least one of an activated carbon filter element 533a, a carbon cloth filter element 533b, and a high-efficiency filter element 533c. That is to say, the rear filter element component 533 may only include the activated carbon filter element 533a, may also only include the carbon cloth filter element 533b, or may include the high-efficiency filter element 533c. Of course, the rear filter element component 533 may also be any two of the activated carbon filter element 533a, the carbon cloth filter element 533b, and the high-efficiency filter element 533c. Or, the rear filter element component 533 may also include the activated carbon filter element 533a, the carbon cloth filter element 533b, and the high-efficiency filter element 533c at the same time. Moreover, the number of the activated carbon filter elements 533a may be one, and of course, it may also be two or more. Similarly, the number of the carbon cloth filter elements 533b may be one, and of course, it may also be two or more. The number of the high-efficiency filter elements 533c may be one, and of course, it may also be two or more.

[0082] In this embodiment, the activated carbon filter element 533a can play a good filtering role for harmful gases (such as formaldehyde, benzene, sulfur dioxide, etc.), odors, and volatile organic compounds (such as volatile compounds in paints and cleaners); the carbon cloth filter element 533b can filter harmful gases, odors, and particulate matters; the high-efficiency filter element 533c can play a good filtering role for ultrafine particulate matters, allergens, bacteria and germs, tiny smoke particles, odors, etc. Thus, effective re-interception and filtration of particulate matters are realized, and / or effective re-filtration of gases, odors, and volatile organic compounds, etc. is realized.

[0083] In an embodiment of the present application, in order to achieve zoned and effective filtration of particles, gases, odors, and volatile organic compounds, etc., please refer to Figure 4, at least two filter elements 534 may be included in the front filter element component 531, namely a primary filter element 531a and a medium - efficiency filter element 531b respectively. At least two or three filter elements 534 may be included in the rear filter element component 533, namely an activated carbon filter element 533a, a carbon - cloth - sandwich filter element 533b, and a high - efficiency filter element 533c respectively. At this time, the primary filter element 531a, the medium - efficiency filter element 531b, the activated carbon filter element 533a, the carbon - cloth - sandwich filter element 533b, and the high - efficiency filter element 533c are arranged in sequence along the air - passing direction. Of course, it may also be that the primary filter element 531a, the medium - efficiency filter element 531b, the carbon - cloth - sandwich filter element 533b, the activated carbon filter element 533a, and the high - efficiency filter element 533c are arranged in sequence along the air - passing direction; or, the primary filter element 531a, the medium - efficiency filter element 531b, the carbon - cloth - sandwich filter element 533b, the high - efficiency filter element 533c, and the activated carbon filter element 533a are arranged in sequence along the air - passing direction. In addition, since it can better meet the effective filtration of each component to be filtered in the process exhaust gas at this time, the number of the primary filter element 531a, the medium - efficiency filter element 531b, the activated carbon filter element 533a, the carbon - cloth - sandwich filter element 533b, and the high - efficiency filter element 533c can all be set to one to simplify the overall number of the filter elements 534. In addition, the materials of the primary filter element 531a, the medium - efficiency filter element 531b, and the high - efficiency filter element 533c can be glass fiber, and of course, it can also be Hepa, or steel wire. The present application does not limit the materials of the primary filter element 531a, the medium - efficiency filter element 531b, and the high - efficiency filter element 533c.

[0084] Please refer to Figures 5 to 13 , in an embodiment of the present application, the cyclone separator 57 includes a base 572 and a cyclone module 571; the cyclone module 571 includes a bracket 573 and at least two cyclone structures 577 connected to the bracket 573. The bracket 573 and the base 572 enclose at least two separated separation chambers 571a and at least two air - inlet channels 571b. The base 572 and / or the bracket 573 are provided with a cyclone inlet 57e. One end of each air - inlet channel 571b is communicated with the cyclone inlet 57e, and the other end is communicated with at least one separation chamber 571a; each cyclone structure 577 is located in a separation chamber 571a.

[0085] In an embodiment of the present application, the cyclone structure 577 includes at least two side - by - side cyclone cylinders 578. A cyclone chamber 578b is formed inside the cyclone cylinder 578. The cyclone cylinder 578 is provided with an air - flow inlet 578a communicating the separation chamber 571a and the cyclone chamber 578b, and the bracket 573 is provided with an air - flow outlet 578c communicating the cyclone chamber 578b.

[0086] In this embodiment, when the air flow enters through the cyclone inlet 57e, it can enter the two separation chambers 571a through the two air inlet channels 571b respectively. After that, the particulate matter mixed in the air flow is separated by the cyclone structure 577 in the separation chamber 571a, and then the air flow enters the air outlet chamber 571c and flows out through the air outlet 578c. At this time, at least two cyclone structures 577 can increase the contact area with the air flow and provide a relatively large space for accommodating particulate matter, so as to reduce the rapid and excessive accumulation of particulate matter, which is beneficial to improving the separation effect of the cyclone separator 57 on the particulate matter mixed in the air flow. Moreover, a set of air flow channels for the air flow to pass through can be shared both upstream and downstream of at least two cyclone structures 577 at this time, so that the structure can be simplified. In addition, the cyclone separator 57 is formed by enclosing the separation chamber 571a and the air inlet channel 571b with the base 572 and the bracket 573, so that the two can be separately and independently manufactured in a more portable manner, and then assembled together to form the separation chamber 571a and the air inlet channel 571b, which is beneficial to improving the convenience of processing and forming the separation chamber 571a and the air inlet channel 571b. In addition, the second surface 57b and the cyclone side wall 57d described above can be formed on the base 572, and the handle 579 can be provided on the base 572.

[0087] Please refer to Figure 10 and Figure 13 , in an embodiment of the present application, the base 572 is provided with at least two separated separation grooves 572b, a cyclone inlet 57e, and at least two air inlet grooves 572a. One end of each air inlet groove 572a communicates with the cyclone inlet 57e, and the other end communicates with at least one separation groove 572b; the bracket 573 covers the openings of the air inlet grooves 572a and the separation grooves 572b, and encloses with the air inlet grooves 572a to form the air inlet channel 571b, and encloses with the separation grooves 572b to form the separation chamber 571a.

[0088] In this embodiment, the cyclone inlet 57e is arranged on the base 572. Meanwhile, a separation groove 572b and an air inlet groove 572a are arranged on the base 572 to enclose a separation chamber 571a and an air inlet passage 571b after the cover bracket 573 is closed, so that only the cyclone structure 577 needs to be arranged on the bracket 573. That is, the cyclone inlet 57e, the separation groove 572b and the air inlet groove 572a are distributed on the base 572 and the bracket 573 together with the cyclone structure 577. As a result, neither the structure on the base 572 nor the structure on the bracket 573 is too complex, improving the convenience of manufacturing the cyclone separator 57. Among them, the separation groove 572b and the air inlet groove 572a can be formed by the surface of the base 572 facing the bracket 573 being recessed. Of course, it can also be that a surrounding plate protrudes from the surface of the base 572 facing the bracket 573, and the surrounding plate and the surface of the base 572 facing the bracket 573 enclose to form them. The bracket 573 can be a flat plate structure, and the cyclone structure 577 is connected to the side facing the base 572.

[0089] Please refer to Figure 7 and Figure 13 , in an embodiment of the present application, the cyclone separator 57 further includes a top cover 574. The top cover 574 is arranged on the bracket 573 and is located outside the separation chamber 571a. The air outlet 578c communicates with the air outlet chamber 571c. The base 572 is provided with a cyclone outlet 57c, and the bracket 573 is provided with a through hole 573d communicating the cyclone outlet 57c and the air outlet chamber 571c.

[0090] In this embodiment, the air outlet chamber 571c can be conveniently connected to multiple cyclone cylinders 578, and then the number of cyclone outlets 57c required can be simplified, which is beneficial to further improving the convenience of manufacturing the cyclone separator 57. At the same time, the air outlet chamber 571c can also rectify the air flow flowing out of the multiple cyclone cylinders 578 so that it flows out along the cyclone outlet 57c orderly, reducing the possibility of turbulent flow of the air flow flowing out of the multiple cyclone cylinders 578. In addition, the first surface 57a introduced above can be formed on the top cover 574. In addition, it should be noted that in other embodiments, it can also be that the top cover 574 is provided with a cyclone outlet 57c communicating with the air outlet chamber 571c; or, the bracket 573 is provided with a cyclone outlet 57c communicating with the air outlet chamber 571c.

[0091] Please refer to Figures 7 to 14, in an embodiment of the present application, the air inlet 578a on the cyclone cylinder 578 can penetrate and be exposed on the side of the bracket 573 away from the base 572. At this time, the base 572 further includes at least two upper covers 575. The at least two upper covers 575 are arranged in the air outlet cavity 571c, and each upper cover 575 is arranged corresponding to a cyclone structure 577 and covers the air outlet 578c. The upper cover 575 is provided with at least two openings 575a and at least two convex rings 575b. Each opening 575a is arranged corresponding to an air outlet 578c. One end of each convex ring 575b surrounds an opening 575a, and the other end passes through the corresponding through hole 571d and is inserted into the corresponding cyclone chamber 578b, and the cross section of the convex ring 575b is smaller than the cross section of the cyclone cylinder 578. At this time, after the air flow enters the cyclone cylinder 578 from the air inlet 578a, it can rotate and separate downward along the gap between the inner side of the cyclone cylinder 578 and the convex ring 575b, and then flow out through the convex ring 575b. Furthermore, the convex ring 575b plays a better isolation role in the rotation separation and outflow of the air flow in the cyclone cylinder 578, and further improves the separation effect of the particulate matter mixed in the air flow.

[0092] The above are only the preferred embodiments of the present application, and do not limit the patent scope of the present application. Any equivalent structural transformation made by using the description and drawings of the present application under the inventive concept of the present application, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present application.
