Description

Technical Field

[0001] This utility model relates to the technical field of handheld laser cleaning machines, and more particularly to a handheld laser cleaning machine. Background Technology

[0002] With the increasing demand for efficient and environmentally friendly cleaning methods in the industrial cleaning sector, laser cleaning technology has gradually gained widespread application due to its advantages such as non-destructive operation, no consumables, and high degree of automation. Handheld laser cleaning machines, as an important branch of laser cleaning equipment, are particularly suitable for rust removal, paint removal, and decontamination of delicate parts or complex workstations due to their small size, portability, and flexible operation. However, existing handheld laser cleaning machines still face some technical challenges that urgently need to be addressed in practical applications.

[0003] First, the laser, as the core component of a handheld laser cleaning machine, generates a significant amount of heat during operation. If heat dissipation is insufficient, it can easily overheat, leading to performance degradation, shortened lifespan, and even potential safety hazards. Existing equipment typically only has an air inlet or a simple fan at one end of the housing, resulting in an inefficient airflow path and low cooling efficiency, failing to effectively remove the laser's heat. Furthermore, some equipment suffers from insufficient structural compactness and an unreasonable internal component layout, further exacerbating the heat dissipation problem. Utility Model Content

[0004] One objective of this invention is to provide a handheld laser cleaning machine to solve the heat dissipation problem of handheld laser cleaning machines.

[0005] To achieve the above objectives, the present invention provides a solution as follows: a handheld laser cleaning machine includes a housing, a laser, a fan, a laser cleaning head, and wires. The housing has a receiving cavity, and air inlets and outlets communicating with the receiving cavity are respectively opened at opposite ends of the housing. The projection of the air inlet toward the air outlet falls within the air outlet. The laser is disposed in the receiving cavity and is located on the line connecting the air inlet and the air outlet. The fan is connected to the housing and disposed at the air inlet and / or the air outlet. The laser cleaning head is detachably connected to the housing. Wires are respectively connected to the laser and the laser cleaning head.

[0006] Optionally, the enclosure includes a bottom plate, a top plate, multiple side plates, and multiple columns. The bottom plate and the top plate are connected to the opposite ends of the multiple columns. Side plates are provided between adjacent columns. The side plates and columns are interlocked. The opposite ends of the side plates are connected to the bottom plate and the top plate, respectively. The bottom plate, the top plate, and the multiple side plates together form an accommodating cavity.

[0007] Optionally, the column includes a main body, a first plate, a second plate, a third plate, and a fourth plate. The first plate and the second plate are disposed on one side of the main body and are spaced apart to form a first clamping groove. The third plate and the fourth plate are disposed on the other side of the main body and are spaced apart to form a second clamping groove. The ends of adjacent side plates are respectively inserted into the first clamping groove and the second clamping groove. The main body, the first plate, and the third plate are respectively provided with screw holes. Screws pass through the screw holes to connect the bottom plate, the top plate, multiple side plates, and multiple columns into a whole.

[0008] Optionally, the width of the first clamping groove gradually narrows in the direction close to the main body, and the width of the second clamping groove gradually narrows in the direction close to the main body.

[0009] Optionally, the handheld laser cleaning machine also includes multiple supports, which are arranged around the air inlet or outlet on the housing, with wires wrapped around the supports.

[0010] Optionally, multiple supports are distributed along the height of the housing into a first layer and a second layer, with the opening directions of the supports in the first layer and the supports in the second layer being opposite.

[0011] Optionally, the bracket includes a first part, a second part, a third part, and a fourth part connected in sequence. The first part is connected to the housing. The first part, the second part, the third part, and the fourth part together form a limiting groove. The end of the fourth part away from the third part extends in a direction away from the first part.

[0012] The beneficial effects of this utility model are as follows: Through the above-mentioned structural design, this technical solution effectively solves the technical problems existing in handheld laser cleaning machines in terms of cooling, ease of operation, and cleaning head protection, thereby achieving multiple technical effects. First, the projection of the air inlet towards the air outlet falls within the air outlet, making the airflow path more direct. Combined with the action of the fan, this significantly improves the cooling efficiency of the laser, preventing performance degradation or damage caused by overheating, and enhancing the stability and service life of the equipment. Second, the laser cleaning head adopts a detachable structure, allowing users to easily remove it during cleaning operations for handheld operation, greatly improving operational flexibility and portability. Simultaneously, when not in use, the cleaning head can be stored in the case, effectively preventing damage during transportation or storage, thus improving the durability and safety of the equipment. Furthermore, the overall structure is compact, easy to carry, and suitable for mobile operations in various scenarios. In summary, this technical solution, through a reasonable structural layout and cooling system design, achieves the advantages of miniaturization, high efficiency, ease of maintenance, and portability in handheld laser cleaning machines, effectively enhancing the practicality and market competitiveness of the equipment.

[0022] This embodiment provides a handheld laser cleaning machine, including a housing 10, a laser 20, a fan 30, a laser cleaning head 40, and a wire 50. Specifically, the housing 10 has an internal cavity for housing components such as the laser 20. An air inlet 101 and an air outlet 102 are respectively located at opposite ends of the housing 10, and both the air inlet 101 and the air outlet 102 are connected to the cavity, allowing for effective airflow within the housing 10. In particular, the projection of the air inlet 101 onto the air outlet 102 falls within the air outlet 102. This structural design ensures that the airflow can pass smoothly and directly through the cavity, maximizing the utilization rate of the cooling airflow. The laser 20 is installed within the cavity and located on the line connecting the air inlet 101 and the air outlet 102, allowing the air flowing through the cavity to directly carry away the heat generated by the laser 20 during operation, enhancing the heat dissipation effect. The fan 30 is connected to the housing 10 and is located at the air inlet 101 and / or air outlet 102 to enhance airflow speed, thereby further improving the cooling efficiency inside the housing 10. The laser cleaning head 40 is detachably connected to the housing 10. Users can remove the laser cleaning head 40 from the housing 10 for easy handheld operation, improving the flexibility and convenience of cleaning operations. When not in use, the laser cleaning head 40 can be stored inside the housing 10 for easy carrying and protection. The wires 50 are connected to the laser 20 and the laser cleaning head 40 respectively, providing power to the laser 20 and transmitting laser signals to ensure the normal operation of the entire equipment.

[0023] In terms of effectiveness, this technical solution, through the aforementioned structural design, effectively solves the technical problems existing in handheld laser cleaning machines regarding cooling, ease of operation, and cleaning head protection, thereby achieving multiple technical benefits. Firstly, the projection of the air inlet 101 onto the air outlet 102 falls within the outlet 102, making the airflow path more direct. Combined with the function of the fan 30, this significantly improves the cooling efficiency of the laser 20, preventing performance degradation or damage due to overheating and enhancing the stability and lifespan of the equipment. Secondly, the laser cleaning head 40 adopts a detachable structure, allowing users to easily remove it during cleaning operations for handheld operation, greatly improving operational flexibility and portability. When not in use, the cleaning head can be stored in the housing 10, effectively preventing damage during transportation or storage, thus improving the equipment's durability and safety. Furthermore, the overall structure is compact and easy to carry, suitable for mobile operations in various scenarios. In summary, this technical solution, through a reasonable structural layout and cooling system design, achieves the advantages of miniaturization, high efficiency, ease of maintenance, and portability in handheld laser cleaning machines, effectively enhancing the equipment's practicality and market competitiveness.

[0024] This embodiment relates to a housing 10 structure for a laser cleaning machine. The housing 10 includes a base plate 11, a top plate 12, multiple side plates 13, and multiple columns 14. Specifically, the multiple columns 14 are arranged along the height direction of the housing 10, and the opposite ends of each column 14 are fixedly connected to the base plate 11 and the top plate 12, respectively, realizing the basic skeletal structure of the housing 10. Side plates 13 are provided between adjacent columns 14, and the side plates 13 and columns 14 are interlocked, enabling quick and stable assembly. The upper and lower ends of the side plates 13 are connected to the base plate 11 and the top plate 12, respectively, further enhancing the positioning and fixing effect of the side plates 13. Through the above structure, the base plate 11, top plate 12, and multiple side plates 13 enclose a spatially enclosed cavity for installing and protecting functional components such as the laser 20 and the fan 30. This cavity not only provides reliable support and protection for the internal components but also facilitates the subsequent layout and installation of components.

[0025] In terms of effectiveness, this technical solution, through the assembly structure of base plate 11, top plate 12, side plates 13, and columns 14, effectively solves the technical problems of existing laser cleaning machine housing 10, such as complex structure, inconvenient assembly and maintenance, and insufficient strength. Firstly, the connection between columns 14 and base plate 11 and top plate 12 forms a stable framework, greatly improving the overall strength and structural stability of housing 10. Secondly, the plug-in design of side plates 13 and columns 14 makes the assembly and disassembly of components simpler and faster, facilitating equipment production, transportation, and subsequent maintenance, effectively reducing manufacturing and maintenance costs. Simultaneously, the connection between the upper and lower ends of side plates 13 and base plate 11 and top plate 12 strengthens the sealing and durability of housing 10, ensuring that the internal components are not easily subjected to external impacts and contamination during transportation and use. Through this structural layout, housing 10 not only possesses excellent mechanical and protective properties but also enhances the modularity and standardization of the laser cleaning machine, thereby achieving efficient assembly, convenient maintenance, and a stable structure, greatly enhancing the practicality and market competitiveness of the laser cleaning machine.

[0026] This embodiment discloses a column structure for a laser cleaning machine housing 10. The column includes a main body 141, a first plate 142, a second plate 143, a third plate 144, and a fourth plate 145. The first plate 142 and the second plate 143 are disposed on one side of the main body 141 and spaced apart from each other, forming a first clamping groove 146. The third plate 144 and the fourth plate 145 are disposed on the other side of the main body 141 and spaced apart from each other, forming a second clamping groove 147. During assembly, the ends of two adjacent side plates 13 are respectively inserted into the first clamping groove 146 and the second clamping groove 147, achieving efficient positioning and stable connection between the side plates 13 and the column. Furthermore, the main body 141, the first plate 142, and the third plate 144 are all provided with screw holes 148, allowing screws to pass through and connect to the bottom plate 11, the top plate 12, the multiple side plates 13, and the multiple columns 14, thereby firmly connecting the various components of the housing 10 into a whole. This structure not only facilitates the quick assembly and disassembly of the side panel 13 and the column, but also significantly improves the overall strength and stability of the box 10 structure.

[0027] In terms of effectiveness, this technical solution simplifies the assembly process of the side plate 13 and the column by setting two sets of clamping slots on the column, allowing the side plate 13 to be directly inserted into the clamping slots of the column. This greatly improves assembly efficiency. Simultaneously, the design of the screw holes 148 and the screw fastening structure allows for multi-point fixing of the bottom plate 11, top plate 12, side plate 13, and column, enhancing the overall rigidity and impact resistance of the enclosure 10 and significantly improving its structural strength. Furthermore, the combination of insertion and fastening ensures stable assembly of each component while facilitating subsequent disassembly and replacement, enabling modular production and maintenance of the equipment and improving product maintainability and service life. The complete insertion of the side plate 13 into the clamping slot and its fastening with screws effectively improves the sealing and protective performance of the enclosure 10, better protecting internal components from external environmental influences. In summary, this technical solution, through the innovative design of the column structure, solves the technical problems of complex assembly, weak connection, and inconvenient maintenance of the existing housing 10 structure, and achieves the technical effects of efficient assembly, stable structure, and convenient maintenance, providing a solid foundation for the practicality and market competitiveness of the laser cleaning machine housing 10.

[0028] This embodiment proposes an improved clamping groove design to optimize the structure of the upright column of the laser cleaning machine housing 10. Specifically, the width of the first clamping groove 146 and the second clamping groove 147 on the upright gradually narrows towards the main body 141. That is, the opening of the clamping groove is wider, while the width of the clamping groove decreases as it gets closer to the main body 141, forming an inwardly tapered wedge or conical structure. During assembly, the side plate 13 is inserted into the clamping groove opening at its end. As the insertion depth increases, the width of the clamping groove gradually decreases, forming a progressively stronger clamping force on the end of the side plate 13, achieving more reliable positioning and fixation.

[0029] In terms of effectiveness, this technical solution effectively solves the problems of inaccurate positioning, wobbling, and easy loosening of the side plate 13 after insertion into the clamping groove by designing the clamping groove with a gradually narrowing width. The gradually narrowing clamping groove can create a self-locking and limiting effect on the end of the inserted side plate 13, so that the side plate 13 is automatically centered and firmly clamped during the assembly process, which greatly improves the assembly accuracy and the reliability of the connection between the column and the side plate 13. This not only simplifies the assembly process and improves the assembly efficiency, but also significantly enhances the overall structural strength and stability of the housing 10. In addition, this structure also has a certain anti-loosening performance, which can effectively prevent the side plate 13 from falling off or loosening due to vibration or deformation even after long-term use or under external impact. In summary, this technical solution solves the problems of insecure assembly and inaccurate positioning of the existing clamping groove by designing the clamping groove width gradient, realizing efficient assembly and stable connection between the side plate 13 and the column, thereby improving the structural strength, durability and reliability of the laser cleaning machine housing 10.

[0030] This embodiment provides a structurally optimized handheld laser cleaning machine, which has multiple supports 60 on the housing 10. Specifically, the multiple supports 60 are arranged around the air inlet 101 or air outlet 102 and fixed to the surface of the housing 10. The supports 60 are spaced apart to form a structural space for winding the wires 50. During use, the power cord or signal cable of the laser cleaning machine can be wound around the supports 60 one by one. Through the guidance and fixation of the supports 60, the wires 50 are effectively stored and organized, preventing them from becoming loose, tangled, or hanging near the air inlet 101 or air outlet 102, thereby affecting the smoothness of air intake and exhaust or causing inconvenience to the machine.

[0031] In terms of effectiveness, this technical solution effectively solves the technical problems of messy, easily tangled, and obstructed airflow in existing handheld laser cleaning machines by setting multiple supports 60 around the air inlet 101 or air outlet 102 and winding the wires 50 around them. This results in reduced safety due to the wires 50 being unruly, easily tangled, affecting airflow, hindering heat dissipation of the housing 10, and compromising usability. The multiple supports 60 allow the wires 50 to be distributed in an orderly manner, preventing them from hanging directly on the air inlet / outlet 102 and ensuring the equipment's ventilation and heat dissipation performance. Simultaneously, the winding structure facilitates quick storage and organization of the wires 50 during mobile installation or storage, improving portability and ease of use. Furthermore, this solution prevents the wires 50 from being damaged or loosened due to accidental pulling, improving the overall safety and reliability of the equipment. In summary, this technical solution, through the optimized design of the supports 60 and the winding structure of the wires 50, achieves orderly management and fixation of the wires 50, improving the structural rationality, safety, and user experience of the handheld laser cleaning machine.

[0032] This embodiment proposes a multi-layer support 60 distribution structure for the wire management structure of a handheld laser cleaning machine. Specifically, the multiple supports 60 are distributed along the height direction of the housing 10, forming a first layer and a second layer. The supports 60 in the first layer and the supports 60 in the second layer have opposite opening directions during installation. For example, the openings of the supports 60 in the first layer face upwards, and the openings of the supports 60 in the second layer face downwards. When the user organizes or winds the wire 50, the wire 50 can pass through the supports 60 in the first and second layers sequentially, forming an interlaced winding structure. Through the staggered layer distribution and opening directions, the wire 50 can be effectively secured between the supports 60 during winding, preventing it from falling off or slipping.

[0033] The aforementioned structure, through its multi-layered brackets 60 with opposite opening directions, effectively solves the technical problems of loose winding, easy slippage, and inconvenient organization of the wires 50 in existing laser cleaning machines. Because the brackets 60 are distributed at different heights and have staggered opening directions, the wires 50 are more securely fixed between the brackets 60 during winding, preventing slippage caused by a single-direction opening. Furthermore, this structure allows for tighter and neater winding of the wires 50, further improving the storage efficiency of the wires 50 and the space utilization of the housing 10. When users move or carry the equipment, the wires 50 are less likely to loosen, improving safety and portability. In summary, this technical solution, through its multi-layered, staggered-opening bracket 60 structure, achieves efficient management and stable storage of the wires 50, improving the product's structural rationality, reliability, and user experience.

[0034] This embodiment relates to a support structure 60 for a handheld laser cleaning machine housing 10. Specifically, the support 60 includes a first part 61, a second part 62, a third part 63, and a fourth part 64 connected in sequence. The first part 61 is fixedly connected to the housing 10 and serves as the mounting base for the entire support 60. The second part 62 is connected to the first part 61, the third part 63 is connected to the second part 62, and the fourth part 64 is connected to the third part 63, forming an enclosure structure. The first part 61, the second part 62, the third part 63, and the fourth part 64 together form a limiting groove 65, which is used to accommodate and limit the position of the wire 50. It is worth noting that the end of the fourth part 64 away from the third part 63 extends away from the first part 61. This structural design makes one side of the limiting groove 65 form an outlet for the wire 50, facilitating the insertion and removal of the wire 50. At the same time, the extension of the fourth part 64 further limits and prevents the wire 50 from falling off.

[0035] Through the above structural design, the bracket 60 effectively solves the technical problems of wires 50 easily falling off, slipping out of the bracket 60, and being poorly fixed. Specifically, the limiting groove 65 structure provides a good storage space for the wires 50, which can stably hold the wires 50 in the groove and prevent the wires 50 from automatically slipping off when the equipment moves or vibrates. The end of the fourth part 64 away from the third part 63 extends away from the first part 61, further forming a shielding and protection effect on the outlet of the limiting groove 65, improving the anti-fall-off performance of the wires 50. Compared with the traditional simple hook-type bracket 60, the combination of the limiting groove 65 and the special extension structure in this embodiment not only makes it convenient for users to put or take out the wires 50 in an orderly manner, but also ensures the stability of the wires 50 when stored, effectively improving the safety and reliability of the product. In addition, this structure also optimizes the organization of the wires 50, making the exterior of the box 10 neater and improving the aesthetics of the product and the user experience. In summary, this technical solution, through its innovative bracket 60 structure, achieves multiple technical effects such as efficient positioning of the conductor 50, prevention of detachment, and ease of operation, thus solving the problems of inconvenient management and easy detachment of the conductor 50 in existing technologies.

[0036] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture. If the specific posture changes, the directional indicator will also change accordingly.

[0037] Furthermore, when an element is referred to as 'fixed to' or 'set on' another element, it may be directly attached to that element, or there may be other intervening elements between them. When an element is referred to as 'connected to' another element, it can be directly connected to the other element or indirectly connected to the other element through an intervening element.

[0038] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, the designation of features such as "first" and "second" can either explicitly express or imply the presence of at least one such feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of a person skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.
