[0050] Please refer to Figure 1 The present application proposes a laser processing system 100 , which includes a laser processing device 10 and a purifier 50 .

[0051] 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 laser processing device 10, as long as it is a device that uses laser as a medium to process the workpiece to be processed. Furthermore, the laser processing device 10 may include a body 11 and a laser head 13, and the body 11 may be provided with a processing chamber 111 and an air inlet 112 and an exhaust port 113 connected to the processing chamber 111. The laser head 30 can be arranged in the processing chamber 111 to emit laser to realize laser processing of the workpiece to be processed placed in the processing chamber 111. In addition, the laser processing device 10 may also include a fan arranged on the body 11 to drive the external air flow to enter through the air inlet 112 and then be discharged through the exhaust port 113. Among them, the fan can be arranged in the processing chamber 111, and of course it can also be arranged in the air inlet 112 or the exhaust port 113.

[0052] The purifier 50 can be used to purify the exhaust gas from the laser processing device 10. Specifically, the purifier 50 can be located outside the housing 11 to reduce the size of the housing 11. In this case, the purifier's air inlet 512 can be connected to the exhaust port 113. Furthermore, the laser processing system 100 can also include a connecting tube 70, one end of which can be connected to the exhaust port 113 and the other end to the purifier 50. Furthermore, to facilitate separate transportation and storage of the purifier 50 and the housing 11, in one embodiment, the connecting tube 70 can be detachably connected to the housing 11 and the purifier 50. Furthermore, to simplify assembly and disassembly, the detachable connection between the connecting tube 70 and the housing 11 and the purifier 50 can be a snap-fit ​​connection or a magnetic connection. Furthermore, to facilitate the placement of the connecting tube 70 in various locations, in one embodiment, the connecting tube 70 can be a hose. Of course, in some embodiments, the purifier 50 can also be located directly within the exhaust port 113. Alternatively, in some embodiments, the purifier 50 may also be disposed in the processing chamber 111 . In this case, the gas outlet 513 of the purifier 50 is connected to the exhaust port 113 .

[0053] Next, the structure of the purifier 50 is explained and described:

[0054] Please refer to Figure 2 In one embodiment of the present application, the purifier 50 includes a housing 51, a filter element 52 and a cyclone separator 57; the housing 51 is provided with an air duct 511 and an air inlet 512 and an air outlet 513 connected to the air duct 511, and the air inlet 512 is configured to be connected to the exhaust port 113; the filter element 52 is provided in the air duct 511; and the cyclone separator 57 is provided in the air duct 511.

[0055] The housing 51 can form a path for the air 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, and of course it can also be connected to the end of the connecting pipe 70 introduced above that is away from the exhaust port 113. Or when the purifier 50 is directly set 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 air on the purifier 50 can be powered by the fan set on the body 10 as described above. Of course, the purifier 50 can also further include a fan to drive the air flow more effectively. In addition, when the purifier 50 is in normal use and with the ground as a reference, the air duct 511 in the housing 51 can be extended in the up and down direction. In other words, it can be said that the wind direction of the air duct 511 (such as Figure 2 The direction (indicated by the dotted arrow) 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 extended in the horizontal direction. The air inlet 512 and the air outlet 513 can be respectively arranged at the two 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 on adjacent sides, or are arranged relative to each other. The present application does not limit the position and shape of the air inlet 512 and the air outlet 513. In addition, the projection of the housing 51 in the up and down directions can be a square or a rectangle, so that its shape is more regular and the convenience of its processing and manufacturing is improved. Among them, the "square or rectangle" here includes the case where the corners are not chamfered, and also includes the case where the corners are rounded or beveled at the boundary. Of course, in other embodiments, the projection of the housing 51 in the up and down directions can also be a circle or other shapes, and the present application does not limit this.

[0056] The filter element 52 can be used to filter components to be filtered from the processing exhaust gas generated by the laser processing device 10. These components to be filtered may include particulate matter, harmful gases, or odors. Furthermore, the number of filter elements 52 can be one, or two or more. Furthermore, when there are two or more filter elements 52, the types of the filter elements 52 can be at least partially different, but they can also be all the same. For example, in one embodiment, there can be five filter elements 52, each comprising a primary filter element, a medium-efficiency filter element, an activated carbon filter element, a carbon cloth filter element, and a high-efficiency filter element, arranged in sequence along the flow direction of the air duct 511. Furthermore, the filter element 52 can be a cube or a rectangular parallelepiped to provide a more regular shape and enhance ease of processing and manufacturing. The term "cube or rectangular parallelepiped" here includes both corners that are not chamfered and corners that are rounded or beveled. Of course, in other embodiments, the filter element 52 can also be cylindrical or have other shapes, and this application is not limiting in this regard. Furthermore, in order to improve the compactness of the distribution and reduce the overall volume of the purifier 50 , in one embodiment, in the wind direction of the air duct 511 , the projected shapes of the housing 51 , the air duct 511 , and the filter element 52 can be set to be the same.

[0057] The cyclone separator 57 can perform high-speed centrifugal separation and collection of particulate matter entrained in the air flow. Specifically, when the number of filter elements 52 is one as described above, the cyclone separator 57 can be located upstream of the filter element 52, or it can be located downstream of the filter element 52. When the number of filter elements 52 is two or more as described above, the cyclone separator 57 can be located upstream of all filter elements 52; it can also be located between two adjacent filter elements 52 to achieve being located upstream of only part of the filter elements 52. For example, when the filter elements 52 include a primary filter element, a medium-efficiency filter element, an activated carbon filter element, a carbon cloth filter element, and a high-efficiency filter element as described above, the cyclone separator 57 can be located upstream of the primary filter element, or it can be located between the medium-efficiency filter element and the activated carbon filter element; or the cyclone separator 57 can be located downstream of all filter elements 52. As can be seen, the present application does not limit the arrangement of the cyclone separator 57 and the filter element 52 within the air duct 511. Furthermore, the number of cyclone separators 57 can be one, or two or more. Furthermore, when there are two or more cyclone separators 57, the at least two cyclone separators 57 can be connected in series, in parallel, or in a combination of both.

[0058] In addition, it should be noted that, in some embodiments, the cyclone separator 57 can also be directly applied to the laser processing device 10. That is, the cyclone separator 57 can be installed outside the machine body 11 and directly communicate with the exhaust port 113 on the machine body 11; or it can be directly installed in the exhaust port 113 or the processing chamber 111 of the machine body and communicate with the processing chamber 111.

[0059] Next, the detailed structure of the cyclone separator 57 will be further explained and illustrated.

[0060] Please refer to Figures 3 to 12 In one 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 isolated 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 connected to the cyclone inlet 57e, and the other end is connected to at least one separation chamber 571a. Each cyclone structure 577 is located in a separation chamber 571a.

[0061] In some embodiments, each cyclone structure 577 includes at least two side-by-side cyclone cylinders 578, a cyclone bin 578b is formed inside the cyclone cylinder 578, the cyclone cylinder 578 is provided with an air flow inlet 578a connecting the separation chamber 571a and the cyclone bin 578b, and the bracket 573 is provided with an air flow outlet 578c connecting the cyclone bin 578b.

[0062] The base 572 and the bracket 573 can be used to cooperate to form a separation chamber 571a and an air inlet channel 571b, wherein the base 572 can be provided with a separation groove 572b and an air inlet groove 572a as described below, so as to respectively enclose the separation chamber 571a and the air inlet channel 571b when the bracket 573 is covered. Of course, the bracket 573 can also be provided with a separation groove 572b and an air inlet groove 572a, so as to respectively enclose the separation chamber 571a and the air inlet channel 571b when the base 572 is covered. Alternatively, the base 572 and the bracket 573 can be provided with a separation groove 572b and an air inlet groove 572a at the same time, so as to respectively enclose the separation chamber 571a and the air inlet channel 571b when the two are relatively covered. It can be seen that this application does not limit the structural type of the base 572 and the bracket 573, and it is sufficient to ensure that the separation chamber 571a and the air inlet channel 571b can be enclosed.

[0063] Furthermore, the cyclone inlet 57e can be set on the base 572, of course, it can also be set on the bracket 573, or it can be formed by the base 572 and the bracket 573. Among them, when the cyclone separator 57 is in normal use, the axis of the cyclone cylinder 578 can be parallel to the up and down direction. At this time, the cyclone inlet 57e can be set on the side wall surface of the base 572 and / or the bracket 573, so as to realize the tangential airflow in the circumference of the cyclone separator 57, better guide the airflow to rotate and increase the flow rate in the cyclone separator 57, and thus help to improve the separation effect of the cyclone separator 57 on the particulate matter mixed in the airflow. Of course, in other embodiments, it is also possible to set the cyclone inlet 57e on other walls of the base 572 and / or the bracket 573. The separation chamber 571a can be arranged in the horizontal direction or in the up and down directions. In addition, the vertical projection of the separation chamber 571a can be circular, so that the airflow can rotate along the circumferential wall of the separation chamber 571a after entering the separation chamber 571a, thereby more evenly entering the various cyclone cylinders 578 in the cyclone structure 577 located within the separation chamber 571a. At this time, in order to facilitate the airflow to enter the separation chamber 571a tangentially, while improving the compactness of the arrangement between the air inlet channel 571b and the separation chamber 571a, and reducing the required size of the cyclone inlet 57e, the air inlet channel 571b can be extended along an arc.

[0064] Of course, in other embodiments, the air inlet channel 571b may also be arranged to extend along a straight line, and the present application does not limit the shape of the air inlet channel 571b. Moreover, the ends of the air inlet channels 571b that are close to each other may be connected, or of course they may be isolated. In addition, the number of air inlet channels 571b may be arranged corresponding to the number of separation chambers 571a. At this time, the end of each air inlet channel 571b away from the cyclone inlet 57e may be connected to a separation chamber 571a. Of course, the number of air inlet channels 571b may also be less than the number of separation chambers 571a. For example: the number of air inlet channels 571b is half the number of separation chambers 571a. At this time, the end of the air inlet channel 571b away from the cyclone inlet 57e may be formed with two branches to be connected to the two separation chambers 571a respectively.

[0065] The cyclone structure 577 may include at least two cyclone cylinders 578 , so as to separate particulate matter by subjecting the airflow to high-speed rotation through the at least two cyclone cylinders 578 . Among them, the cyclone cylinder 578 can include a main cylinder 5781, a side protrusion 5783 and a conical cylinder 5782; the side protrusion 5783 can be protruded on the outside of one end of the main cylinder 5781, and extended along the tangential direction of the main cylinder 5781 to form an airflow inlet 578a for tangential air intake; at the same time, the main cylinder 5781 is opened at one end close to the side protrusion 5783, and is connected to the bracket 573 and the corresponding airflow outlet 578c; the conical cylinder 5782 can be set at one end of the main cylinder 5781 away from the airflow side protrusion 5783, and the inner side of the conical cylinder 5782 is connected to the inner side of the main cylinder 5781 to cooperate in forming a cyclone bin 578b, and in the direction in which the main cylinder 5781 approaches the conical cylinder 5782, the cross-section of the conical cylinder 5782 can be reduced.

[0066] Of course, in other embodiments, the cyclone cylinder 578 may also include only the side protrusion 5783 and the conical cylinder 5782. In this case, the end of the conical cylinder 5782 with a larger cross-section can be directly connected to the bracket 573, and the side protrusion 5783 can be provided at the end of the conical cylinder 5782 with a larger cross-section. In addition, in order to improve the compactness of the distribution of the cyclone cylinder 578 and the separation chamber 571a, multiple cyclone cylinders 578 can be distributed in a circular array on a projection plane perpendicular to the up and down directions. In addition, the airflow outlet 578c can be connected to the subsequent airflow channel through the cyclone outlet 57c provided on the base 572 or the top cover 574 as described below, or it can be directly connected to the subsequent airflow channel. For example: when the cyclone separator 57 is applied to the purifier 50 as described above, the airflow outlet 578c can be directly connected to the air duct 511 of the housing 51 of the purifier 50, or it can be connected to the air duct 511 through the cyclone outlet 57c.

[0067] The cyclone separator 57 of the technical solution of the present application is provided with at least two separation chambers 571a formed by a base 572 and a bracket 573, and is equipped with at least two cyclone structures 577, so that the airflow entering from the cyclone inlet 57e can be separated from the particles by the at least two cyclone structures 577, thereby increasing the accommodating space for the particles, reducing the rapid and excessive accumulation of the particles in the cyclone separator 57, and thereby reducing the required cleaning frequency of the cyclone separator 57.

[0068] Moreover, the contact area with the airflow can be increased by at least two cyclone structures 577, so that the particulate matter entrained in the airflow can be separated more fully and quickly, thereby helping to improve the separation effect and efficiency of the airflow. In addition, the upstream and downstream of at least two cyclone structures 577 still share a set of airflow structures for the airflow to pass through, so that the structure of the cyclone separator 57 can also be simplified. In addition, the cyclone separator 57 is enclosed by the base 572 and the bracket 573 to form the separation chamber 571a and the air inlet channel 571b, so that the two can be separated for more portable independent manufacturing first, and then assembled together to form the separation chamber 571a and the air inlet channel 571b, thereby helping to improve the convenience of processing and forming the separation chamber 571a and the air inlet channel 571b.

[0069] Please refer to Figures 5 to 10 ,as well as Figure 12 In one embodiment of the present application, the base 572 is provided with at least two isolated separation slots 572b, a cyclone inlet 57e and at least two air inlet slots 572a, one end of each air inlet slot 572a is connected to the cyclone inlet 57e, and the other end is connected to at least one separation slot 572b; the bracket 573 covers the notches of the air inlet slot 572a and the separation slot 572b, and encloses the air inlet slot 572a to form an air inlet channel 571b, and encloses the separation slot 572b to form a separation cavity 571a.

[0070] In this embodiment, the cyclone inlet 57e is disposed on the base 572, and a separation groove 572b and an air inlet groove 572a are also disposed on the base 572. When the bracket 573 is closed, a separation chamber 571a and an air inlet channel 571b are enclosed to form the separation chamber 571a. This allows the bracket 573 to be provided with only the cyclone structure 577. In other words, the cyclone inlet 57e, the separation groove 572b, the air inlet groove 572a, and the cyclone structure 577 are distributed on the base 572 and the bracket 573. This reduces the complexity of the structures on both the base 572 and the bracket 573, thereby improving the ease of manufacturing the cyclone separator 57. The separation groove 572b and the air inlet groove 572a can be formed by recesses on the surface of the base 572 facing the bracket 573. Alternatively, a panel can be provided on the surface of the base 572 facing the bracket 573, with the panel enclosing the surface of the base 572 facing the bracket 573. The bracket 573 may be a flat plate structure, and connected to the cyclone structure 577 on the side facing the base 572 .

[0071] Please refer to Figure 8 and Figure 11In one embodiment of the present application, the base 572 is provided with an airflow guide portion 572c in the area opposite to the cyclone inlet 57e, and in the direction from the cyclone inlet 57e toward the airflow guide portion 572c, the cross-sectional size of the airflow guide portion 572c gradually increases and extends toward the two adjacent air inlet channels 571b to guide the airflow diversion into the two adjacent air inlet channels 571b.

[0072] The airflow guide portion 572c can separate and guide the airflow in contact so as to divert it into the two air inlet channels 571b. When the cyclone inlet 57e has a relatively long length in its wind direction, the airflow guide portion 572c can be arranged in the cyclone inlet 57e and located near one end of the air inlet channel 571b. Of course, the airflow guide portion 572c can also be arranged at the connection between the two air inlet channels 571b. In addition, the airflow guide portion 572c can be a convex block structure, or of course, it can be two plate structures at an angle. In addition, the opposite sides of the airflow guide portion 572c can be inclined surfaces or curved surfaces, which can ensure that the opposite sides gradually expand in the direction away from the cyclone inlet 57e to guide the airflow.

[0073] In this embodiment, the airflow guide 572c guides and diverts the airflow, allowing it to enter the air inlet channel 571b more smoothly, thereby maintaining a high air velocity and improving the subsequent separation of particulate matter. Furthermore, in other embodiments, when the air inlet slot 572a is provided on the bracket 573, the bracket 573 may also be provided with the airflow guide 572c.

[0074] Please refer to Figure 11 In one embodiment of the present application, two adjacent air inlet channels 571b include adjacent channel walls 571b3. The two adjacent channel walls 571b3 are connected at one end near the cyclone inlet 57e and are spaced apart from the cyclone inlet 57e. The airflow guide portion 572c is protruding from the connection between the two adjacent channel walls 571b3. In one embodiment of the present application, the airflow guide portion 572c can be conical, with the top of the cone facing the cyclone inlet 57e. The airflow guide portion 572c can be integrally formed with the two adjacent channel walls 571b3, or be disposed between the cyclone inlet 57e and the two adjacent channel walls 571b3.

[0075] In this embodiment, the two air inlet channels 571b are connected at one end near the cyclone inlet 57e, providing sufficient space for the airflow guide portion 572c. This also simplifies the layout of the cyclone inlet 57e and the air inlet channels 571b, thereby facilitating the manufacturing of the cyclone separator 57. When the base 572 is provided with the air inlet slots 572a as described above, the adjacent channel walls 571b3 may be the adjacent slot walls of the two adjacent air inlet slots 572a.

[0076] Please refer to Figure 8 、 Figure 11 as well as Figure 12 In one embodiment of the present application, the axis of the cyclone cylinder 578 is parallel to the first direction, and at least two separation chambers 571a are arranged in sequence in a second direction intersecting the first direction.

[0077] When the cyclone separator 57 is in normal use, the first direction may be the up-down direction as described above, and the second direction may be a horizontal direction.

[0078] In this embodiment, the separation chamber 571a is arranged in the horizontal direction so that at least two air inlet channels 571b can be located at the same height. This can simplify the shape of the air inlet channel 571b on the basis of achieving tangential air intake to each separation chamber 571a, thereby facilitating the manufacturing of the cyclone separator 57.

[0079] Please refer to Figure 12 In one embodiment of the present application, the cyclone inlet 57e is located on one side of at least two separation chambers 571a in the second direction, and at least two air inlet channels 571b are located on opposite sides of the separation chamber 571a in the third direction, and the third direction intersects the first direction and the second direction.

[0080] When the first direction is the up-down direction, the second direction may be the left-right direction, and the third direction may be the front-back direction.

[0081] In this embodiment, the cyclone inlet 57e is disposed on the left or right wall of the base 572, and the two air inlet channels 571b are distributed on both sides in the front-to-back direction. This allows the air inlet channels 571b to effectively utilize the left-to-right space of the base 572, thereby reducing the need to enlarge the size of the base 572 in the front-to-back direction, thereby reducing the overall volume of the cyclone separator 57. Of course, it should be noted that the present application is not limited to this. In other embodiments, the cyclone inlet 57e can be disposed on the front or rear wall of the base 572 and located between the two separation chambers 571a.

[0082] Please refer to Figure 11In one embodiment of the present application, the at least two separation chambers 571a include a first separation chamber 571a1 and a second separation chamber 571a2, and the first separation chamber 571a1 is closer to the cyclone inlet 57e than the second separation chamber 571a2; the at least two air inlet channels 571b include a first air inlet channel 571b1 and a second air inlet channel 571b2, and the first air inlet channel 571b1 is connected to the side of the first separation chamber 571a1 close to the second separation chamber 571a2, and the second air inlet channel 571b2 is connected to the side of the second separation chamber 571a2 close to the first separation chamber 571a1.

[0083] When the cyclone inlet 57e is provided on the left side wall of the base 572, the first separation chamber 571a1 may be located on the left side, and the second separator may be located on the right side.

[0084] In this embodiment, the first air inlet channel 571b1 is connected to the right side of the first separation chamber 571a1, while the second air inlet channel 571b2 is connected to the left side of the second separation chamber 571a2. This allows the airflow paths of the first air inlet channel 571b1 and the second air inlet channel 571b2 to be comparable, thereby improving the uniformity of airflow entering the first and second separation chambers 571a1, 571a2. Furthermore, to improve the compactness of the distribution of the air inlet channel 571b and the separation chamber 571a, and to facilitate tangential airflow into the separation chamber 571a, thereby increasing the rotation effect and flow rate of the airflow, the first air inlet channel 571b1 can surround a portion of the first separation chamber 571a1, and the second air inlet channel 571b2 can surround a portion of the first separation chamber 571a1.

[0085] Please refer to Figure 9 and Figure 9 ,as well as Figure 12 and Figure 13 In one embodiment of the present application, the cyclone separator 57 also includes a top cover 574, which is arranged on the bracket 573 and is located on the outside of the separation chamber 571a. The top cover 574 and the bracket 573 are combined to form an air outlet chamber 571c, and the air flow outlet 578c is connected to the air outlet chamber 571c; the base 572 is provided with a cyclone outlet 57c, and the bracket 573 is provided with an air hole 573d connecting the cyclone outlet 57c and the air outlet chamber 571c.

[0086] In this embodiment, the air outlet cavity 571c can be conveniently connected to multiple cyclone cylinders 578, which can then simplify the number of cyclone outlets 57c required to be set, thereby further improving the convenience of processing and manufacturing the cyclone separator 57. At the same time, the air outlet cavity 571c can also rectify the airflow flowing out of the multiple cyclone cylinders 578 so that it flows out in an orderly manner along the cyclone outlet 57c, reducing the possibility of turbulence in the airflow flowing out of the multiple cyclone cylinders 578. In addition, it should be noted that in other embodiments, the top cover 574 may be provided with a cyclone outlet 57c connected to the air outlet cavity 571c; or, the bracket 573 may be provided with a cyclone outlet 57c connected to the air outlet cavity 571c.

[0087] Please refer to Figure 3 、 Figure 4 、 Figure 6 as well as Figure 7 In one embodiment of the present application, the axis of the cyclone cylinder 578 is parallel to the first direction, and the top cover 574 and the base 572 are respectively arranged on opposite sides of the bracket 573 in the first direction; the base 572 is provided with a cyclone outlet 57c, and the cyclone outlet 57c passes through the base 572 in the first direction.

[0088] When the first direction is the up and down direction as described above, the top cover 574 is set on the upper side of the bracket 573, and the base 572 is set below the bracket 573, so that the air outlet cavity 571c and the separation cavity 571a are arranged in the up and down direction.

[0089] In this embodiment, the air outlet cavity 571c is arranged above each separation cavity 571a, which can improve the compactness of the stacking and further reduce the overall volume of the cyclone separator 57. The cyclone outlet 57c is passed through the lower surface of the base 572, so that the bottom of the cyclone separator 57 can be exhausted, thereby facilitating the upstream air flow channel and the downstream channel of the cyclone separator 57 to be arranged at an angle, so as to further improve the compactness of the structural distribution. At the same time, when the cyclone separator 57 is used in the purifier 50, it is also convenient to arrange the cyclone separator 57 upstream of at least one filter element 52, so as to pre-separate the particulate matter entrained in the air flow through the pre-placed cyclone separator 57, reduce the filtering burden downstream of the cyclone separator 57, and reduce the replacement frequency of the filter element 52.

[0090] Please refer to Figure 6 、 Figure 7 、 Figure 12 as well as Figure 13In one embodiment of the present application, the airflow inlet 578a on the cyclone cylinder 578 can be exposed on the side of the bracket 573 facing away from the base 572. In this case, the base 572 further includes at least two upper covers 575, which are arranged in the air outlet cavity 571c, and each upper cover 575 is arranged corresponding to a cyclone structure 577 and covers the airflow 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 airflow outlet 578c, and one end of each convex ring 575b is arranged around 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 airflow enters the cyclone cylinder 578 from the airflow 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. The convex ring 575b then plays a better isolation role in the rotation separation and outflow of the airflow in the cyclone cylinder 578, further improving the separation effect of particulate matter mixed in the airflow.

[0091] In one embodiment of the present application, in order to simplify the disassembly and assembly of the cyclone separator 57 and facilitate the cleaning of the cyclone separator 57, the top cover 574 can be detachably connected to the base 572 by screw connection, magnetic connection or snap connection, and the upper cover 575 and the bracket 573 can be clamped between the top cover 574 and the base 572. In addition, in order to facilitate the positioning and installation of the base 572. Please refer to Figure 6 and Figure 9 The bracket 573 may be provided with a first annular rib 573a, and the upper cover 575 may be installed and limited in the first annular rib 573a. At the same time, the bracket 573 may also be provided with a positioning rib 573b, and the upper cover 575 may be provided with a positioning hole 575c, and the positioning rib 573b may be inserted into the positioning hole 575c. Similarly, please refer to Figure 5 、 Figure 9 as well as Figure 12 The bracket 573 may further be provided with a second annular rib 573c along its circumference, and the second annular rib 573c may abut against the inner side of the top cover 574. In addition, to facilitate the top cover 574 to clamp the upper cover 575 and the bracket 573, the top cover 574 may further be provided with an abutting rib 574a, so that part of the abutting rib 574a abuts against the upper cover 575, and part of the abutting rib 574a abuts against the bracket 573.
