[0002] Laser processing devices, such as laser cutting devices, etc., play an important role in modern industrial processing with their high precision and high efficiency. During the use of laser cutting devices, a large amount of smoke and dust is generated due to the high-temperature ablation of materials, and the smoke and dust cause pollution to the precision components of the device, seriously affecting the service life and cutting performance of the laser cutting device.

[0003] Some laser cutting and engraving devices use a fan module to exhaust the generated dust or smoke under engraving or cutting conditions. When the laser processing device operates for a long time, dust particles will gradually adhere to the surface of the fan module, resulting in problems such as a decrease in the fan module's wind speed or damage. The fan module is generally fixed to the laser processing device by screws, with a complex structure and it is not easy to quickly disassemble and assemble the fan or clean the dirt on the fan.

Detailed implementation manners

[0054] The technical solution of the present application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described in the present application are only a part of the embodiments, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments provided in the present application without creative efforts belong to the protection scope of the present application.

[0055] In the present application, the mention of "embodiment" means that the specific features, structures or characteristics described in connection with the embodiment may be included in at least one embodiment of the present application. The phrase appears in various positions in the specification does not necessarily refer to the same embodiment, nor is it an exclusive, independent or alternative embodiment to other embodiments. Those skilled in the art can explicitly and implicitly understand that the embodiments described in the present application can be combined with other embodiments.

[0056] The terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example: a component or device including one or more components is not limited to the one or more components listed, but optionally further includes one or more components not listed but inherent to the product shown, or one or more components that should be possessed based on the described function.

[0057] The present application provides a laser processing device. Generally, for a laser processing device, such as a laser engraving device, etc., a fan module is provided as a smoke exhaust system. Most fan modules are fixed to the whole machine by screws, that is, the fan module and the whole machine are fixed by structural parts and screws. When there is a lot of dirt adhered to the surface of the fan module and it is not cleaned for a long time, this will lead to an increase in the failure rate of the fan module itself and the dust, soot, etc. in the device cannot be timely discharged from the device space to the outside through the smoke exhaust pipe. At the same time, the dust, smoke, etc. accumulated in the device space will slowly spread from the device to the outside of the device. And the fan module needs special tools or fixtures to disassemble, and even most of the device housing needs to be removed before the fan module can be disassembled for cleaning the surface of the fan module, resulting in cumbersome cleaning operations for the fan module.

[0058] Please refer to Figure 1a and Figure 1b, the present application provides a fan module 100 that is convenient for disassembly and replacement, and a laser processing device 1000 having the fan module 100. The laser processing device 1000 further includes a housing 200 and a laser head (not shown), and the space enclosed by the housing 200 includes a laser processing space (not shown). The laser head is disposed within the housing 200. Optionally, the laser head may be disposed within the laser processing space or in the laser processing space. Among them, the substrate to be processed is disposed within the laser processing space, and the laser head emits a laser beam into the laser processing space to process the substrate to be processed. In some scenarios, due to the laser ablation of the material at high temperature, soot is generated in the laser processing space.

[0059] At least a part of the fan module 100 is disposed within the housing 200, and the fan module 100 forms an exhaust duct communicating the laser processing space with the external space or a smoke exhaust duct, and the fan module 100 is used for exhausting smoke from the laser processing space.

[0060] Optionally, the air inlet of the fan module 100 is communicated with the laser processing space, and the air outlet of the fan module 100 is communicated with a smoke exhaust duct (not shown). When the fan module 100 starts to rotate, it can effectively discharge the soot from the laser processing space to the smoke exhaust duct or the outside, as Figure 1a shown by the dotted arrow in the figure.

[0061] The present application does not specifically limit the position of the fan module 100 disposed on the housing 200. Optionally, the fan module 100 may be disposed on the back side of the housing 200 ( Figure 1a the position shown), or on the left side of the housing 200 (the left hand side with Figure 1a as the reference perspective), or on the right side of the housing 200 (the right hand side with Figure 1a as the reference perspective), or the bottom side of the housing 200, etc.

[0062] Please refer to Figures 2 to 5 , the fan module 100 includes a housing assembly 30, a fan assembly 20 and a clamping assembly 60.

[0063] Optionally, the outer surface of the housing assembly 30 is a part of the housing of the laser processing device 1000. On the one hand, it makes the fan module 100 share some structures with the housing, reducing the number of structures and the overall volume of the laser processing device 1000.

[0064] The housing assembly 30 is used to accommodate the fan assembly 20, and the fan assembly 20 is detachably connected to the housing assembly 30. The fan assembly 20 can be easily disassembled from the housing assembly 30 to facilitate the replacement of the fan assembly 20.

[0065] Since the outer surface shell of the housing assembly 30 is a part of the housing of the laser processing equipment 1000 , the fan assembly 20 can be easily removed from and installed on the entire housing of the laser processing equipment 1000 .

[0066] See also Figure 6 The housing assembly 30 includes a receiving shell 301 .

[0067] The receiving shell 301 is roughly rectangular in shape and has a receiving groove 301a. The receiving groove 301a is roughly rectangular in shape.

[0068] Specifically, the opening of the receiving groove 301a faces the outside of the laser processing device 1000. For ease of description, the depth direction of the receiving groove 301a is the second direction D2. The side facing the opening of the receiving groove 301a is the front side of the receiving shell 301, and the side away from the opening of the receiving groove 301a is the rear side of the receiving shell 301.

[0069] See also Figure 6 The receiving shell 301 includes a groove portion 3011 and an edge portion 3012 arranged around the groove portion 3011. The groove portion 3011 and the edge portion 3012 are integrally formed. The groove portion 3011 has a receiving groove 301a.

[0070] At least part of the housing assembly 30 is integrally formed with at least part of the housing 200 , and the opening of the receiving groove 301 a is located on the outer surface of the housing 200 , so that the fan assembly 20 can be easily removed and installed from the entire housing 200 of the laser processing equipment 1000 .

[0071] See also Figure 7 The edge portion 3012 includes a first edge portion 3121, a second edge portion 3122 and a third edge portion 3123 that are bent and connected in sequence. The second edge portion 3122 is arranged along the third direction D3. The first edge portion 3121 and the third edge portion 3123 both extend along the first direction D1. The first edge portion 3121 and the third edge portion 3123 are opposite to each other along the second direction D2.

[0072] The locking assembly 60 includes a locking protrusion 3041 and a locking ear portion 2021. The locking ear portion 2021 is bent and extended to surround a locking groove 2022.

[0073] In an alternative embodiment, the engaging bump 3041 protrudes from the side wall of the receiving groove 301a, and the engaging ear portion 2021 is provided on the outer side wall of the fan assembly 20. In this embodiment, by designing the engaging bump 3041 to protrude from the side wall of the receiving groove 301a and the engaging ear portion 2021 to be provided on the outer side wall of the fan assembly 20, it is convenient for the engaging bump 3041 and the engaging ear portion 2021 to be engaged and limited on the side wall of the fan assembly 20, further utilizing the side space of the fan assembly 20 and avoiding excessive dimensions in other directions of the fan assembly 20.

[0074] In another alternative embodiment, the engaging bump 3041 is provided on the outer side wall of the fan assembly 20, and the engaging ear portion 2021 is provided on the side wall of the receiving groove 301a. In this embodiment, by designing the engaging bump 3041 to be provided on the outer side wall of the fan assembly 20 and the engaging ear portion 2021 to be provided on the side wall of the receiving groove 301a, it is convenient for the engaging bump 3041 and the engaging ear portion 2021 to be engaged and limited on the side wall of the fan assembly 20, further utilizing the side space of the fan assembly 20 and avoiding excessive dimensions in other directions of the fan assembly 20.

[0075] The present application does not specifically limit the number of the engaging bumps 3041. For example, the number of the engaging bumps 3041 can be one, or two, or three, or four, etc. Optionally, the number of the engaging grooves 2022 corresponds to the number of the engaging bumps 3041 one by one.

[0076] Please refer to Figures 9 to 11 , taking one of the engaging bumps 3041 as an example, the engaging bump 3041 protrudes from the side wall of the receiving groove 301a, and the engaging ear portion 2021 is provided on the outer side wall of the fan assembly 20. The engaging ear portion 2021 is bent and extended to surround and form the engaging groove 2022. The engaging groove 2022 and the engaging ear portion 2021 are arranged along the second direction D2. Among them, the engaging groove 2022 is located in front of the engaging ear portion 2021.

[0077] The engaging bump 3041 can move from the first position to the second position. When the engaging bump 3041 is located at the first position, the engaging bump 3041 is engaged with the engaging ear portion 2021, and the fan assembly 20 is limited within the receiving groove 301a. When the engaging bump 3041 is located at the second position, the engaging bump 3041 is disengaged from the engaging ear portion 2021, and the fan assembly 20 can be removed from the receiving groove 301a.

[0078] Optionally, please refer to Figures 9 to 11The side wall of the receiving shell 301 is provided with a third through hole 301b connected to the receiving groove 301a. The engaging protrusion 3041 extends into the receiving groove 301a through the third through hole 301b, and the third through hole 301b is used for the engaging protrusion 3041 arranged outside the receiving groove 301a to extend into the receiving groove 301a.

[0079] Furthermore, the size of the third through hole 301b along the first direction D1 is greater than the size of the engaging protrusion 3041 along the first direction D1, so that the engaging protrusion 3041 can move along the first direction D1 in the third through hole 301b, specifically from the first position along the first direction D1 to the second position. In this embodiment, the movement from the first position along the first direction D1 to the second position is a vertical upward movement. The first direction D1 may be perpendicular to the second direction D2.

[0080] Of course, in other embodiments, the movement of the first position to the second position along the first direction D1 may also be a downward movement.

[0081] When the engaging protrusion 3041 is set at the first position, the engaging protrusion 3041 is set in the engaging groove 2022, and the engaging protrusion 3041 is engaged with the engaging ear portion 2021 in the second direction D2. At this time, the fan assembly 20 is located in the receiving groove 301a under the engagement of the engaging protrusion 3041 and the engaging ear portion 2021, and the fan assembly 20 is in a locked state locked in the housing assembly 30.

[0082] When the locking protrusion 3041 is set to the second position, the locking protrusion 3041 moves to the outside of the locking groove 2022, and the position of the locking protrusion 3041 is offset from the position of the locking ear portion 2021 in the second direction D2. At this time, the fan assembly 20 is no longer subject to a restraining force in the second direction D2. When the fan assembly 20 is subjected to an outward thrust in the second direction D2, the fan assembly 20 can be moved out of the receiving groove 301a. At this time, the fan assembly 20 is in an unlocked state.

[0083] The fan module 100 provided by the present application, the fan module 100 includes a housing assembly 30 and a fan assembly 20, the housing assembly 30 includes a receiving housing 301, and the receiving housing 301 has a receiving groove 301a. The engaging assembly 60 includes an engaging protrusion 3041 and an engaging ear 2021, and the engaging ear 2021 is bent and extended to surround and form an engaging groove 2022; the engaging protrusion 3041 protrudes from the side wall of the receiving groove 301a, and the engaging ear 2021 is provided on the outer side wall of the fan assembly 20; alternatively, the engaging protrusion 3041 is provided on the outer side wall of the fan assembly 20, and the engaging ear 2021 is provided on the side wall of the receiving groove 301a. The engaging protrusion 3041 can move from a first position to a second position; when the engaging protrusion 3041 is located at the first position, the engaging protrusion 3041 is engaged with the engaging ear 2021, and the fan assembly 20 is limited in the receiving groove 301a, which is convenient for installing the fan assembly 20 in the housing assembly 30. The engaging protrusion 3041 is disengaged from the engaging ear 2021, and the fan assembly 20 is in a locked state locked in the housing assembly 30; when the engaging protrusion 3041 is located at the second position, the fan assembly 20 is in an unlocked state, and the fan assembly 20 can be removed from the receiving groove 301a under an external force, so as to facilitate removing the fan assembly 20 from the housing assembly 30, and further facilitate disassembly, installation and replacement.

[0084] Compared with designing the fan module 100 as a non-detachable module structure, after dust accumulates on the fan module 100, it is troublesome to disassemble the fan module 100, and the housing assembly 30 needs to be disassembled together; in the present application, by setting the fan assembly 20 and the housing assembly 30 to be detachably connected, and the fan assembly 20 is the main structure where dust is likely to accumulate. Therefore, after dust accumulates on the fan assembly 20, the fan assembly 20 can be separately disassembled or replaced from the housing assembly 30, simplifying the difficulty of disassembly and installation operations.

[0085] In this application, a latching projection 3041 that can move along the first direction D1 is provided on the fan assembly 20, and a latching ear 2021 and a latching groove 2022 corresponding to the latching projection 3041 are provided on the outer wall of the fan assembly 20, so as to facilitate moving the position of the latching projection 3041, making the latching projection disposed in the latching groove 2022, and the latching projection 3041 is latched with the latching ear 2021 in the second direction D2. When the latching projection 3041 moves outside the latching groove 2022, the positions of the latching projection 3041 and the latching ear 2021 are offset in the second direction D2. At this time, the fan assembly 20 is no longer subject to a binding force in the second direction D2. When an outward thrust is applied to the fan assembly 20 in the second direction D2, the fan assembly 20 can be moved out of the receiving groove 301a under the action of an external force. At this time, the fan assembly 20 is in an unlocked state. The fan assembly 20 can be conveniently disassembled and installed from the housing assembly 30.

[0086] Optionally, the latching projection 3041 moves from the first position to the second position along the first direction D1, and the fan assembly 20 moves into the receiving housing 301 along the second direction D2. The latching projection 3041 extends along the third direction D3, and the first direction D1, the second direction D2, and the third direction D3 intersect pairwise. Optionally, the first direction D1 intersects the second direction D2. Further optionally, the first direction D1 and the second direction D2 can be perpendicular. Optionally, the first direction D1 intersects the third direction D3. Further optionally, the first direction D1 and the third direction D3 can be perpendicular. Optionally, the second direction D2 intersects the third direction D3. Further optionally, the second direction D2 and the third direction D3 can be perpendicular.

[0087] For example, the latching projection 3041 moves from the first position to the second position along the height direction, the fan assembly 20 moves into or out of the receiving groove 301a along the width direction, and the latching projection 3041 extends along the length direction.

[0088] In this embodiment, by designing the extending direction of the latching projection 3041 to intersect (be perpendicular to) the direction in which the fan assembly 20 moves into or out of the receiving groove 301a, it is convenient to limit the fan assembly 20, and the space on the side of the fan assembly 20 is also utilized. In addition, in this embodiment, by designing the extending direction of the latching projection 3041 to be perpendicular to the moving direction, it is convenient to drive the latching projection 3041 to engage with or disengage from the latching groove 2022 on the outer wall of the fan assembly 20.

[0089] In an alternative embodiment, please refer to Figure 8 , Figure 10a , Figure 11 and Figure 12 , the latching assembly 60 further includes a first elastic member 306.

[0090] The first elastic member 306 is disposed along the first direction D1. The first elastic member 306 includes, but is not limited to, structures such as springs, elastic sheets, and elastic rubbers that can generate recoverable elastic deformations in the first direction D1. In this embodiment, the first elastic member 306 is taken as an example of the first spring.

[0091] Please refer to Figure 8 , Figure 10a and Figure 11 , and both ends of the first elastic member 306 are respectively abutted between the first positioning block 3011 protruding from the receiving shell 301 along the second direction D2 and the engaging convex block 3041. In other words, the rear side of the first edge portion 3121 of the receiving shell 301 has a first positioning block 3011 protruding along the second direction D2.

[0092] The upper end of the first elastic member 306 abuts against the first positioning block 3011, and the lower end of the first elastic member 306 abuts against the engaging convex block 3041.

[0093] The engaging assembly 60 further includes a connecting block 304. A part of the connecting block 304 extends into the receiving groove 301a to form the engaging convex block 3041. In this embodiment, the connecting block 304 is installed on the receiving shell 301. The connecting block 304 is disposed at the rear side of the receiving shell 301, and the connecting block 304 is connected to the edge portion 3012 along the second direction D2. The connecting block 304 and the receiving shell 301 are connected together along the second direction D2, and the connecting block 304 and the receiving shell 301 can move relative to each other in the first direction D1. That is, the connecting block 304 can have a certain position relative to the receiving shell 301 in the first direction D1.

[0094] Optionally, please refer to Figure 4 and Figure 8 , the connecting block 304 includes a first bending arm 3040, an intermediate main arm 3042, and a second bending arm 3043 that are sequentially bent and connected and interconnected as a whole. The first bending arm 3040 is attached to and connected to the first edge portion 3121. The intermediate main arm 3042 is attached to and connected to the second edge portion 3122. The second bending arm 3043 is attached to and connected to the third edge portion 3123.

[0095] Please refer to Figure 8 , the connecting block 304 further includes an engaging convex block 3041 protruding from the side wall of the receiving groove 301a. The present application does not specifically limit the position where the engaging convex block 3041 is disposed on the side wall of the receiving groove 301a. Optionally, the engaging convex block 3041 can be disposed on at least one of the first bending arm 3040, the intermediate main arm 3042, and the second bending arm 3043.

[0096] In other embodiments, the connecting block 304 can also extend in one direction, for example, it can be the first bending arm 3040, etc. At this time, the engaging bump 3041 can be provided on the first bending arm 3040.

[0097] In other embodiments, the connecting block 304 can also extend in two directions, for example, it can be the middle main arm 3042 and the first bending arm 3040, etc. At this time, the engaging bump 3041 can be provided on the first bending arm 3040 and / or the middle main arm 3042.

[0098] In other embodiments, the connecting block 304 can also extend in four directions. For example, the connecting block 304 includes a first bending arm 3040, a middle main arm 3042, a second bending arm 3043, and a third bending arm (not shown) that are connected end to end in sequence. Among them, the engaging bump 3041 can be provided on at least one of the first bending arm 3040, the middle main arm 3042, the second bending arm 3043, and the third bending arm.

[0099] Specifically, the housing 301 and the connecting block 304 are relatively fixed in the second direction D2, and the housing 301 and the connecting block 304 can move relative to each other in the first direction D1. Optionally, a strip-shaped hole (or waist-shaped hole) extending in the first direction D1 is provided on the connecting block 304. The connecting block 304 and the housing 301 are fixed in the second direction D2 by a screw extending in the second direction D2 to restrict the relative fixation of the housing 301 and the connecting block 304 in the second direction D2. Since the screw passes through the strip-shaped hole extending in the first direction D1 and the screw and the connecting block 304 can move relative to each other in the first direction D1, and the screw fixedly connects the housing 301, the connecting block 304 can move relative to the screw in the first direction D1.

[0100] Multiple sets of combinations of the strip-shaped holes and screws in the first direction D1 provided on the connecting block 304 and the housing 301 can be provided. For example, at least two combinations of the strip-shaped holes and screws in the first direction D1 are arranged in the third direction D3, and at least two combinations of the strip-shaped holes and screws in the first direction D1 are arranged in the first direction D1 to ensure that the housing 301 and the connecting block 304 can stably slide relative to each other in the first direction D1.

[0101] In this embodiment, the connecting block 304 can slide up and down relative to the housing 301 under the action of an external force.

[0102] During the process of installing the fan assembly 20 into the receiving housing 301 along the second direction D2, the engaging ear portion 2021 first presses against the engaging convex block 3041. The engaging convex block 3041 compresses the first elastic member 306 upward (at this time, the connecting block 304 can move upward as a whole relative to the receiving housing), and the first elastic member 306 is compressed. Under the action of the engaging ear portion 2021 of the fan assembly 20, the engaging convex block 3041 moves from the first position along the first direction D1 to the second position. The engaging ear portion 2021 smoothly enters the receiving groove 301a without being blocked by the engaging convex block 3041. When the fan assembly 20 is located within the receiving groove 301a (when installed in place), the engaging ear portion 2021 no longer presses against the engaging convex block. The engaging convex block 3041 moves in the reverse direction of the first direction D1 to the first position under the action of the first elastic member 306. At this time, the engaging groove 2022 corresponds to the first position. Therefore, the engaging convex block 3041 returns to the first position, that is, the engaging groove 2022, under the elastic restoring force of the first elastic member 306. The engaging ear portion 2021 cannot move out of the receiving groove 301a along the second direction D2 due to the blocking action of the engaging convex block 3041, that is, the fan assembly 20 is locked within the housing assembly 30 is achieved.

[0103] Please refer to Figure 6 and Figure 8 , the engaging assembly 60 further includes a pressing assembly 40. The pressing assembly 40 is provided on the receiving housing 301.

[0104] The pressing assembly 40 abuts against the connecting block 304.

[0105] Optionally, the pressing assembly 40 is configured to push the connecting block 304 to move along the first direction D1, so that the engaging convex block 3041 moves from the first position to the second position. In other words, the connecting block 304 can slide up and down relative to the receiving housing 301 under the action of the pressing assembly 40. That is, the pressing assembly 40 provides the force for the connecting block 304 to slide up and down relative to the receiving housing 301, that is, provides the force for the engaging convex block 3041 to compress the first elastic member 306 and move from the first position to the second position.

[0106] During the unlocking process, by pressing the pressing assembly 40, the pressing assembly 40 pushes the connecting block 304 to move along the first direction D1, so that the engaging convex block 3041 moves from the first position to the second position. At this time, the engaging convex block 3041 moves out of the engaging groove 2022, and the engaging ear portion 2021 is no longer resisted by the engaging convex block 3041 in the second direction D2. At this time, the fan assembly 20 can be moved out of the receiving groove 301a under the action of an external force in the second direction D2 to achieve the unlocked state of the fan assembly 20.

[0107] This application does not specifically limit the setting direction of the pressing component 40. For example, the pressing component 40 is arranged at the bottom of the housing component 30 along the first direction D1. Pressing the pressing component 40 upward along the first direction D1 pushes the connecting block 304 to move upward along the first direction D1, causing the engaging convex block 3041 to move from the first position to the second position. For another example, the pressing component 40 is arranged at the top of the housing component 30 along the first direction D1, and the pressing component 40 and the connecting block 304 are rotatably connected by a rotating rod. The two sides of the rotation center of the rotating rod are respectively connected to the pressing component 40 and the connecting block 304. When the pressing component 40 is pressed downward along the first direction D1, it pushes the connecting block 304 to move upward along the first direction D1, causing the engaging convex block 3041 to move from the first position to the second position.

[0108] For another example, the pressing component 40 is arranged on the left side wall or the right side wall of the housing component 30 along the first direction D1, and the pressing component 40 and the connecting block 304 are abutted by two inclined plane blocks. When the pressing component 40 moves along the third direction D3, the pressing component 40 pushes the connecting block 304 to move upward along the first direction D1, causing the engaging convex block 3041 to move from the first position to the second position.

[0109] For another example, the pressing component 40 is arranged on the front side of the edge portion 3012. The pressing component 40 is arranged along the second direction D2. The front surface of the edge portion 3012 can be the appearance surface of the laser processing device 1000, so that the operator can directly perform the pressing operation, install the fan assembly 20, and disassemble the fan assembly 20 from the appearance surface of the laser processing device 1000 (specifically, the same side of the fan module 100).

[0110] For further details, please refer to Figure 8 、 Figure 13 and Figure 14 , the pressing component 40 is arranged along the second direction D2. The pressing component 40 includes a first inclined plane block 401 extending along the second direction D2.

[0111] Please refer to Figure 8 、 Figure 13 and Figure 14 , the connecting block 304 further includes a second inclined plane block 3044. The extending direction of the second inclined plane block 3044 is parallel to the first direction D1.

[0112] The first inclined plane of the first inclined plane block 401 abuts against the second inclined plane of the second inclined plane block 3044. When the first inclined plane block 401 moves along the second direction D2, it pushes the second inclined plane block 3044 to move along a direction parallel to the first direction D1.

[0113] In other words, the first inclined surface and the second inclined surface are at least partially in contact. For example, when viewed in cross-section, the first inclined surface slopes backward and downward, and the second inclined surface slopes backward and downward.

[0114] When the pressing assembly 40 is pressed, the pressing assembly 40 moves backward along the second direction D2. The first inclined surface block 401 pushes the second inclined surface block 3044 backward, and under the action of the first inclined surface block 401, the second inclined surface block 3044 moves upward along the first direction D1. That is, the connecting block 304 as a whole moves upward along the first direction D1, and the engaging convex block 3041 moves upward from the first position to the second position along the first direction D1. The above process can convert the fan assembly 20 in the locked state into the unlocked state. In this way, in this embodiment, by a simple operation, the unlocking of the fan assembly 20 can be achieved, enabling the fan assembly 20 to be detached and replaced. This not only achieves the smoke exhaust and protection effect but also makes the disassembly and replacement operations of the smoke exhaust fan simple and convenient, saving time and cost.

[0115] The present application does not specifically limit the position where the pressing assembly 40 is provided on the receiving housing 301. Optionally, the pressing assembly 40 can be provided on the second edge portion 3122. Further, the second edge portion 3122 has a keyhole, a part of the pressing assembly 40 is provided in the keyhole, and the end of the pressing assembly 40 for pressing can protrude relative to the keyhole.

[0116] Please refer to Figure 8 、 Figure 13 and Figure 14 As shown in FIGS. and, the housing assembly 30 further includes a limiting block 303. The limiting block 303 is fixed to the side of the connecting block 304 facing away from the receiving housing 301. At least a part of the limiting block 303 is disposed opposite to the edge portion 3012 of the receiving housing 301. The limiting block 303 is fixedly connected to the receiving housing 301, and the connecting block 304 slides between the limiting block 303 and the receiving housing 301. Further, both the limiting block 303 and the receiving housing 301 have circular fixing holes, and the connecting block 304 has a strip-shaped fixing hole disposed along the first direction D1. A fixing screw sequentially passes through the circular fixing hole of the limiting block 303, the strip-shaped fixing hole on the connecting block 304, and the circular fixing hole on the receiving housing 301 to fix the limiting block 303 and the receiving housing 301. Since the fixing hole on the connecting block 304 is a strip-shaped fixing hole disposed along the first direction D1, the connecting block 304 can move relative to the receiving housing 301 and the limiting block 303 along the first direction D1.

[0117] Please refer to Figure 8 and Figure 15, the connecting block 304 further includes a first through hole 3045. The second inclined surface block 3044 protrudes from the hole wall of the first through hole 3045. Specifically, the second inclined surface block 3044 protrudes from the upper hole wall of the first through hole 3045. The second inclined surface of the second inclined surface block 3044 faces the side where the pressing assembly 40 is located.

[0118] Please refer to Figure 8 , Figures 13 - 15 , the pressing assembly 40 further includes a pressing part 402 and a second elastic member 403.

[0119] The pressing part 402 is arranged opposite to the first through hole 3045. One end (the rear end) of the pressing part 402 abuts against the inner side of the receiving shell 301, and the other end (the front end) of the pressing part 402 exposes through the key hole on the receiving shell 301.

[0120] The first inclined surface block 401 protrudes from one end of the pressing part 402 towards the rear end.

[0121] The second elastic member 403 penetrates through the first through hole 3045. The second elastic member 403 elastically abuts between the pressing part 402 and the limiting block 303. Further, the pressing part 402 further has a fixing post protruding along the second direction D2, the second elastic member 403 is sleeved on the fixing post, the fixing post is arranged in the first through hole 3045, and there is a certain distance between the rear end of the fixing post and the limiting block 303, so that the pressing part 402 has a certain pressing process. One end of the second elastic member 403 abuts against the pressing part 402, and the other

[0122] The second elastic member 403 includes but is not limited to a spring, a spring sheet, an elastic rubber, an elastic silica gel, etc. In this application, the second elastic member 403 is taken as an example of a spring for illustration.

[0123] When the pressing part 402 is pressed, the second elastic member 403 is compressed, the first inclined surface block 401 moves towards the rear side along the second direction D2, and the second inclined surface block 3044 moves upward along the first direction D1 under the action of the first inclined surface block 401. At this time, the connecting block 304 as a whole moves upward along the first direction D1, that is, the engaging convex block 3041 also moves upward from the first position to the second position along the first direction D1. The above process can realize the conversion of the fan assembly 20 in the locked state to the unlocked state.

[0124] When the fan assembly 20 is in the unlocked state, the fan assembly 20 can be moved out of the receiving groove 301a under the thrust acting on the front side along the second direction D2.

[0125] When the pressing force of the pressing portion 402 is removed, the restoring force of the second elastic member 403 pushes the pressing portion 402 to move toward the front along the second direction D2, and the first inclined block 401 moves toward the front along the second direction D2 accordingly. The second inclined block 3044 moves toward the front along the second direction D2 along with the first inclined surface, and under the action of the elastic restoring force of the first elastic member 306, the locking protrusion 3041 is pushed gradually downward to the first position.

[0126] Optionally, the pressing assembly 40 is disposed near the middle position of the second edge portion 3122. The first through hole 3045 is disposed on the middle main arm 3042. Further, the first bending arm 3040 and the second bending arm 3043 may be symmetrically disposed about the central axis of the connecting block 304 along the first direction D1.

[0127] Optionally, the number of the engaging protrusions 3041 is two. The two engaging protrusions 3041 are respectively arranged on the first bending arm 3040 and the second bending arm 3043 along the third direction D3. Specifically, one engaging protrusion 3041 is convexly arranged on the first bending arm 3040 along the third direction D3, and the other engaging protrusion 3041 is convexly arranged on the third bending arm along the third direction D3. The two side walls of the receiving groove 301a along the third direction D3 are both provided with third through holes 301b, and the two engaging protrusions 3041 are respectively convexly arranged in the receiving groove 301a through the two third through holes 301b.

[0128] Correspondingly, the number of the first elastic members 306 is two, and the two second elastic members 403 abut against the two engaging protrusions 3041 respectively.

[0129] Furthermore, there are two latching ears 2021, which are respectively arranged on two opposite side walls of the fan assembly 20 along the third direction D3. When the fan assembly 20 is in the locked state, the two engaging protrusions 3041 are respectively engaged with the two latching ears 2021 to increase the balance and stability of the engaging force of the fan assembly 20.

[0130] In an optional embodiment, when the fan assembly 20 is in the unlocked state, the fan assembly 20 can be moved out by manually pushing it.

[0131] In an alternative embodiment, see Figure 5 and Figure 6 The fan module 100 further includes an ejection assembly 50. The ejection assembly 50 is compressed when the fan assembly 20 is in a locked state, and the ejection assembly 50 pushes the fan assembly 20 to pop out of the receiving groove 301a when the fan assembly 20 is in an unlocked state, so that after the operator presses the pressing assembly 40, the fan assembly 20 can be automatically ejected under the action of the ejection assembly 50, and the fan assembly 20 does not need to be manually removed from the housing assembly 30.

[0132] In this embodiment, the distance at which the fan assembly 20 is ejected is designed such that the distance at which the fan assembly 20 is ejected from the housing assembly 30 is convenient for pinching with the hand, and will not cause the fan assembly 20 to be completely ejected, resulting in damage to the fan assembly 20 due to dropping.

[0133] During the actual operation, the pressing portion 402 of the pressing assembly 40 is disposed adjacent to the fan assembly 20, and single-handed operation can be performed when disassembling the fan assembly 20. For example, the pressing assembly 40 is pressed with the index finger, and the ejected fan assembly 20 can be pinched with the thumb and little finger.

[0134] Optionally, please refer to Figure 5 and Figure 6 , the ejection assembly 50 includes a push plate 501 and a third elastic member 502.

[0135] The push plate 501 and the third elastic member 502 are sequentially disposed between the bottom of the fan assembly 20 and the bottom wall of the receiving groove 301a.

[0136] The ejection assembly 50 is configured to eject the fan assembly 20 from the receiving groove 301a when the engaging bump 3041 is disposed at the second position, that is, when the fan assembly 20 is in an unlocked state.

[0137] The third elastic member 502 includes at least one spring disposed along the second direction D2. The third elastic member 502 is in a compressed state when the fan assembly 20 is locked in the receiving groove 301a, and elastically recovers when the fan assembly 20 is in an unlocked state, and pushes the push plate 501 and the fan assembly 20 to eject a certain distance.

[0138] Optionally, the third elastic member 502 includes a plurality of springs arranged in parallel.

[0139] Please refer to Figure 5 and Figure 6 , the push plate 501 includes, but is not limited to, a hollow plate. Optionally, the receiving groove 301a is a rectangular groove. The push plate 501 is a hollow rectangular plate. Four columns 503 are respectively provided at four corners of the push plate 501. The third elastic member 502 includes four springs, and each spring is respectively sleeved on a column 503. Each spring elastically abuts against the push plate 501 and the bottom wall of the receiving groove 301a.

[0140] Please refer to Figure 5 and Figure 6, the four columns 503 also pass through four fourth through - holes at the bottom of the receiving groove 301a. One end of each of the four columns 503 passing through the four fourth through - holes is respectively fixed with four screws 504. The columns 503 cooperate with the screws 504, enabling the four columns 503 to move a certain distance in the fourth through - holes along the second direction D2. However, the push plate 501 and the screws 504 will limit the movement stroke of the columns 503 along the second direction D2.

[0141] Specifically, the push plate 501 is installed in four holes opposite to the housing assembly 30. The screws 504 fix and limit the columns 503 assembled to the push plate 501. The third elastic member 502 elastically abuts between the push plate 501 and the bottom wall of the receiving groove 301a. When the push plate 501 is pressed, there is a certain elastic force and stroke to assist in ejecting the fan assembly 20. The stroke distance of the push plate 501 and the third elastic member 502 in the ejection assembly 50 is relatively moderate, not so large as to eject outside the housing of the device and cause damage to the fan assembly 20, achieving the effect of ejecting a small distance.

[0142] Please refer to Figure 16 , the side of the push plate 501 has at least one extension 5011. Further, the shape of the receiving groove 301a is adapted to the push plate 501. The extension 5011 is used to guide the push plate 501 into the receiving groove 301a on one hand, and on the other hand, the extension 5011 cooperates with the side wall of the receiving groove 301a to limit the push plate 501.

[0143] For example, extension parts 5011 extending outwards are provided on both opposite sides of the push plate 501 along the third direction D3. The two extension parts 5011 are used to play a guiding role when the push plate 501 enters the receiving groove 301a and also limit the position of the push plate 501 in the first direction D1.

[0144] Further, inside the receiving groove 301a, the limiting protrusion is located in front of the push plate 501.

[0145] The bottom of the receiving groove 301a has a hollow structure so that when the fan assembly 20 is installed on the housing assembly 30, the hollow channel of the push plate 501 and the hollow channel at the bottom of the receiving groove 301a both form part of the air duct.

[0146] Generally, when the fan module 100 is disassembled from the whole machine, it is also necessary to manually remove the wires or terminal clips connected to the fan module 100. And during the process of removing the wires, it is very likely to damage the wires or terminal clips. After the wires are broken, it may cause a short - circuit when starting up and damage the whole machine.

[0147] The fan module 100 provided by this application can also reduce the damage to wires and terminal clips when the fan assembly 20 is disassembled.

[0148] Specifically, please refer to Figure 6 , the housing assembly 30 further includes a second circuit board 210 and an electrical connection base 2101 disposed on the second circuit board 210. Among them, the electrical connection base 2101 includes, but is not limited to, an electrical connection base 2101 (a gold finger base) that is a conductive terminal. The interface of the electrical connection base 2101 faces the front side along the second direction D2.

[0149] Please refer to Figure 17 and Figure 18 , the fan assembly 20 further includes a first circuit board 206 and a conductive terminal group 2062 disposed on the first circuit board 206. The conductive terminals in the conductive terminal group 2062 extend along the second direction D2. The conductive terminals in the conductive terminal group 2062 extend rearward along the second direction D2.

[0150] The fan assembly 20 is located in the receiving groove 301a. The electrical connection base 2101 is electrically connected to the conductive terminal group 2062. When the fan assembly 20 is removed from the receiving groove 301a, the electrical connection base 2101 is disconnected from the conductive terminal group 2062.

[0151] When the fan assembly 20 is inserted into the receiving groove 301a along the second direction D2, each conductive terminal of the conductive terminal group 2062 can be inserted into each interface of the electrical connection base 2101 along the second direction D2. In this way, the process of installing the fan assembly 20 and the electrical connection process of the fan assembly 20 and the housing assembly 30 are the same process; the process of disassembling the fan assembly 20 and the disconnection process of the fan assembly 20 and the housing assembly 30 are the same process, without the need to additionally operate the conductive terminal group 2062 and the electrical connection base 2101 of the fan assembly 20 and the housing assembly 30, and the installation and disassembly direction of the fan assembly 20 is along the extension direction of the conductive terminal group 2062. Therefore, the installation and disassembly direction of the fan assembly 20 in this application will not damage the conductive terminals; in addition, the disconnection process of the fan assembly 20 and the housing assembly 30 does not involve wires. Therefore, the installation and disassembly direction of the fan assembly 20 in this application will not damage the wires, reducing damage to the wires and terminal blocks when the fan assembly 20 is disassembled.

[0152] The fan assembly 20 is an independent integral structure, which facilitates the operator to replace and use multiple fan assemblies 20 at different time periods, that is, insert multiple fan assemblies 20 into the housing assembly 30 for rotation at different times. When the operator cleans the dirt of one fan assembly 20, immediately insert another fan assembly 20 into the corresponding receiving groove 301a of the housing assembly 30 in the laser processing device 1000. At this time, the laser processing device 1000 can continue to work immediately without being affected by the time for cleaning the dirt, greatly improving the disassembly and assembly efficiency and experience of the operator.

[0153] Please refer to Figure 17 , the fan assembly 20 includes a first fan sub-assembly 20b and a second fan sub-assembly 20a.

[0162] Optionally, a clamping portion 2042 is convexly provided on the inner surface of the fan housing 204. The clamping portion 2042 faces the first circuit board 206 and has a clamping groove. One end of the first circuit board 206 is arranged in the clamping groove. The clamping portion 2042 clamps and fixes one end of the first circuit board 206.

[0163] Please refer to Figure 17 and Figure 18 , the electrical connection module 212 includes a first circuit board 206, a first socket 2011, a second socket 2061 and a conductive terminal group 2062. The first socket 2011 is electrically connected to the fan module 201. The second socket 2061 and the conductive terminal group 2062 are spaced apart on the first circuit board 206. The first socket 2011 is electrically connected to the second socket 2061. The conductive terminal group 2062 is electrically connected to the second socket 2061. The above realizes the electrical connection between the conductive terminal group 2062 and the fan module 201.

[0164] Among them, the second socket 2061 can be a circuit board socket. The first socket 2011 can be a cable socket. The first socket 2011 and the second socket 2061 are electrically connected to realize the electrical connection between the cable of the fan module 201 and the circuit board, and the conductive terminal group 2062 is exposed outside the fan housing 211.

[0165] The buffer module 209 is provided (specifically, pasted) between the fan housing 211 and the fan module 201, playing a role in vibration prevention, vibration reduction and noise reduction.

[0166] The second fan assembly 20 can be an independent assembly, facilitating insertion and removal along the top opening 211b, and making it easier for the user to clean the dust and dirt adhering to the first fan sub-assembly 20b and the second fan sub-assembly 20a respectively. When cleaning the dirt, the second fan assembly 20 does not require the removal of fasteners such as the first socket 2011, screws or nuts, saving the cumbersome operation of the operator during cleaning and enabling more convenient and quick assembly with the first fan assembly 20.

[0167] Please refer to Figure 5 and Figure 6 , the fan module 100 further includes a wind guide cover 309 and a foam 308. The wind guide cover 309 is provided on the side (rear side) of the receiving housing 301 facing away from the fan assembly 20. The foam 308 is provided on one side of the receiving housing 301 and the wind guide cover 309.

[0168] Furthermore, both the wind guide cover 309 and the foam 308 are hollow structures to form a part of the air duct.

[0169] During the assembly process, the fan assembly 20 is gently pushed into the receiving slot 301a of the housing assembly 30 while being aligned. The engaging protrusion 3041 of the connecting block 304 locks with the engaging ear 2021 of the fan front housing 202, and at the same time, the conductive terminal group 2062 on the second circuit board 210 is quickly connected to the electrical connection seat 2101 of the first circuit board 206. At this time, the engaging grooves 2022 on both sides of the fan front housing 202 lock with the engaging protrusions 3041 at the connecting block 304, and the fan assembly 20 is installed in place. The circuit is normally conducted, and the fan can be started and rotated at any time to quickly and effectively discharge the soot from the device to the exhaust duct or outdoors. At this time, the fan assembly 20 is subjected to the elastic force of the third elastic member 502 on the push plate 501.

[0170] When the operator needs to remove the fan assembly 20, press down the pressing portion 402, and the first inclined surface of the first inclined surface block 401 pushes the second inclined surface of the second inclined surface block 3044 of the connecting block 304. When the pressing portion 402 is pressed with a force perpendicular to the limiting block 303, it will drive the connecting block 304 to move upward. The engaging protrusion 3041 of the connecting block 304 disengages from the engaging ear 2021 of the fan front housing 202. At this time, the third elastic member 502 is quickly released, and at the same time, the pressing portion 402 rebounds to the original position, the connecting block 304 returns to the original position, and the push plate 501 ejects the fan assembly 20 by a short stroke. At this time, the operator can conveniently remove the fan assembly 20 from the housing assembly 30 with one hand.

[0171] Due to the elastic force exerted by the third elastic member 502 on the entire fan assembly 20, the conductive terminal group 2062 on the second circuit board 210 located in the fan assembly 20 disengages from the electrical connection seat 2101 of the first circuit board 206, thereby quickly ejecting the fan assembly 20.

[0172] The fan module 100 provided by the present application facilitates quick disassembly, assembly, or replacement of a brand-new fan assembly 20 by the operator, effectively solving the problem of the fan motor being blocked or even the motor circuit being damaged due to long-term accumulation of dirt on the fan without cleaning. By adopting the structure of the pressing part 402 and cooperating with the second elastic part 403, locking the clamping ear part 2021 on the fan module 100 can smoothly install and disassemble the entire fan module 100, which can greatly reduce the requirements for disassembly and improve the experience and efficiency.

[0173] The fan module 100 provided by the present application adopts an integrated electrical connection structure of the electrical connection module 212, that is, it reduces the cable breakage or circuit short-circuit faults caused by the operator disassembling the fan and then assembling and wiring.

[0174] The present application adopts a double quick-disassembly function. By using the ejection of the pressing part 402 and the guiding of the chute, the module can be quickly disassembled from the whole machine with at least only one hand or two fingers, without the need to use tools such as a screwdriver. Thus, when the operator needs to clean the fan module 100, the function of this quick-disassembly fan module 100 can be exerted to the highest efficiency. Under the same conditions and in a similar structure under the same working conditions, the present application can adopt fewer costs and more compact structural parts, and the disassembly is also easier, which can effectively improve the operator's use experience and the disassembly, assembly, maintenance efficiency, reduce the difficulty of disassembling the fan and cleaning the fan dirt, and make the disassembly, assembly, maintenance, or replacement of the entire fan module 100 more convenient.

[0175] The laser processing device 1000 further includes a guide rail assembly (not shown). The guide rail assembly is disposed within the housing 200. The guide rail assembly includes, but is not limited to, at least one of an X-axis guide rail, a Y-axis guide rail, or a Z-axis guide rail.

[0176] In an alternative embodiment, the laser head (not shown) is disposed on the guide rail assembly. The guide rail assembly is used to drive the laser head to move to complete a preset laser processing operation, etc.

[0177] In another alternative embodiment, the laser processing device 1000 further includes a guide rail assembly (not shown) and a processing platform (not shown). The guide rail assembly and the processing platform are disposed within the housing 200. The processing platform is connected to the guide rail assembly. The guide rail assembly is used to drive the processing platform to move relative to the laser head to complete a preset laser processing operation, etc. The substrate to be processed is disposed on the processing platform. In this embodiment, the laser head may not move.

[0178] In yet another alternative embodiment, the number of the guide rail assemblies is two groups, and the laser head is disposed on one group of guide rail assemblies. The processing platform is connected to the other group of guide rail assemblies, so that the positions of the laser head and the substrate to be processed on the processing platform can be relatively changed to complete a preset laser processing operation and the like.

[0179] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present application. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present application, and these improvements and refinements are also regarded as the protection scope of the present application.
