Description

Technical Field

[0001] This utility model belongs to the field of fanless laser light technology, and in particular relates to a fanless laser light with a replaceable dust filter. Background Technology

[0002] A laser light is a device that generates a laser beam. Laser lights typically use YAG solid-state lasers, generating a laser beam through a krypton lamp and an Nd:YAG crystal rod, which is then frequency-converted to produce visible light. Fanless laser lights are those that do not rely on a fan for cooling, instead using heat dissipation vents, dust filters, or other methods.

[0003] For example, CN219082984U discloses a fanless laser lighting fixture, including a base with a frame on top. A laser light is housed inside the frame, and an adjustment assembly is located inside the laser light. The adjustment assembly includes an inner cylinder rotatably connected to the laser light, a slider fixedly connected to the outer surface of the inner cylinder, a groove inside the laser light, and a mounting clip fixedly connected inside the inner cylinder. This fanless laser lighting fixture uses a battery to power the laser emitters, enabling multiple sets of laser emitters of different colors to illuminate the stage. Simultaneously, a first motor rotates a fixed plate and the inner cylinder, causing the inner cylinder to rotate and thus the laser emitters to change the laser illumination effect. A second motor rotates a worm gear, which in turn rotates a worm wheel and a shaft, causing the laser light to rotate, thereby increasing the laser illumination range and expanding the stage rendering area.

[0004] The above-mentioned patent has the following defects in use:

[0005] The dustproof and breathable mesh is fixedly connected to the bottom of the laser lamp for ventilation and heat dissipation of the first motor and the laser emitter. However, during long-term use, the blocked dust tends to accumulate on the surface of the dustproof and breathable mesh, which reduces the ventilation effect of the mesh. Furthermore, it is not easy to disassemble, thus affecting the ventilation and heat dissipation of the first motor and the laser emitter. Therefore, this utility model proposes a fanless laser lamp with a replaceable dust filter. Utility Model Content

[0006] This utility model provides a fanless laser lamp with a replaceable dust filter. An insertion limiting mechanism allows for the movable installation of the filter body and the laser lamp tube. Simultaneously, an insertion fastening mechanism reinforces the installation between the filter body and the laser lamp tube, preventing loosening and ensuring installation stability. The movable installation between the filter body and the laser lamp tube allows for easy disassembly and replacement of the filter body when excessive dust accumulates on its surface, ensuring the filter body's air permeability and thus guaranteeing the laser lamp tube's ventilation and heat dissipation. In summary, this invention solves the problems in the prior art.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0033] In the description of this utility model, it should be understood that the terms "relative", "one end", "inner", "lateral", "end", "both ends", "both sides", "front", "one end face", "the other end face", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Specific Implementation Example 1:

[0035] Please see Figures 1-6 As shown, the present invention relates to a fanless laser light with a replaceable dust filter, comprising:

[0036] The mounting frame 1 and the laser tube 2 are mounted. The inner wall of the mounting frame 1 is rotatably connected to a pair of rotating rods 13 via bearings. The ends of the pair of rotating rods 13 that are close to each other are fixedly connected to the outer wall of the laser tube 2. The laser tube 2 is provided with a mounting base 6 inside. Multiple laser emitter bodies 7 are fixedly connected to the top of the mounting base 6. A round opening is cut at the bottom of the laser tube 2. A filter body 8 that is in close contact with its inner wall is provided inside the round opening.

[0037] Multiple insertion limiting mechanisms 10 are provided on the bottom end of the laser tube 2, and the insertion limiting mechanisms 10 are used for the installation and removal of the filter body 8.

[0038] Multiple insertion and fastening mechanisms 11 are provided on the bottom end of the laser tube 2, and the insertion and fastening mechanisms 11 are used to reinforce the installation of the filter body 8.

[0039] The insertion limiting mechanism 10 includes a concave cylindrical block 1001. Multiple connecting sleeves 9 are fixedly connected to the outer wall of the filter body 8, and the connecting sleeves 9 are sleeved on the outer wall of the concave cylindrical block 1001. A pair of vertical plates 1003 are fixedly connected to the top of the concave cylindrical block 1001. A pair of flipping pressure plates 1004 are rotatably connected between the opposite sides of the pair of vertical plates 1003 through bearings and a rotating shaft. The bottom ends of the pair of flipping pressure plates 1004 are in contact with the top of the connecting sleeves 9. Round rods 1006 are fixedly connected to both sides of the pair of flipping pressure plates 1004. Movable protrusions 1005 and springs 1008 are respectively sleeved on the outer walls of the round rods 1006. Four pairs of limiting grooves 1007 are chiseled on the opposite sides of the pair of vertical plates 1003. The pair of movable protrusions 1005 are engaged with the pair of limiting grooves 1007 in the vertical direction in the initial state.

[0040] In the specific implementation process, multiple laser emitter bodies 7 emit lasers of different colors for irradiation. The filter body 8 dissipates the heat generated by the multiple laser emitter bodies 7 inside the laser lamp tube 2 during operation, while filtering and preventing external dust from entering the laser lamp tube 2. As the filter body 8 is used for a long time, more and more dust accumulates on its surface, affecting air circulation. First, the insertion fastening mechanism 11 is operated to loosen the fixation of multiple connecting sleeves 9. Then, multiple pairs of flipping pressure plates 1004 are flipped downwards by 90 degrees in sequence, causing the flipping pressure plates 1004 to drive a pair of movable protrusions 1005 to move. The pair of movable protrusions 1005 first move along the round rod 1006 towards the flipping pressure plate 1004 under compression, and compress the spring 1008, causing the pair of movable protrusions 1005 to engage with a pair of vertical limiting grooves 1007. Moving away, a pair of movable protruding cylinders 1005 are flipped from a horizontal state to a vertical state along with the flipping pressure plate 1004. After the flipping is completed, they extend into a pair of limiting grooves 1007 in the horizontal direction through the elastic action of the spring 1008, and engage, thereby removing the clamping limit of the flipping pressure plate 1004 on the connecting sleeve block 9. Immediately afterwards, the connecting sleeve block 9 is pulled downward to separate from the concave cylindrical block 1001, so that the filter body 8 moves downward until it is separated from the laser lamp tube 2 for disassembly. Then, the new filter body 8 is inserted into the round hole, and the connecting sleeve block 9 is driven to fit onto the concave cylindrical block 1001. Then, multiple pairs of flipping pressure plates 1004 are flipped to a horizontal state in sequence to clamp and limit the connecting sleeve block 9, thereby realizing the replacement and installation of the filter body 8, ensuring the air permeability of the filter body 8, and thus ensuring the ventilation and heat dissipation effect of the laser lamp tube 2.

[0041] Among them, an inner convex circular groove 1002 is chiseled between the top and bottom ends of the connecting sleeve block 9, and the inner wall of the inner convex circular groove 1002 is in close contact with the outer wall of the outer concave cylindrical block 1001.

[0042] By matching the shape of the inner convex circular groove 1002 with the outer concave cylindrical block 1001, the connecting sleeve 9 can play a guiding role when it is fitted onto the outer wall of the outer concave cylindrical block 1001, making it less prone to positional displacement.

[0043] One end of the spring 1008 is fixedly connected to one end of the movable protrusion 1005, and the other end of the spring 1008 is fixedly connected to the side of the flipping pressure plate 1004 near the movable protrusion 1005.

[0044] The elastic extension and contraction of the spring 1008 enables the movement of the movable protrusion 1005, causing it to contract when compressed, so as to assist the movable protrusion 1005 in moving along the round rod 1006. After the compression is completed, the movable protrusion 1005 is driven to return to its original position.

[0045] Among them, an internal straight plate 3 is fixedly connected between the inner walls of the laser lamp tube 2, and the bottom end of the internal straight plate 3 is in contact with the top end of the filter body 8. A first motor 4 is fixedly connected to the top end of the internal straight plate 3, and a rotating circular plate 5 is fixedly connected to the output end of the first motor 4. The top end of the rotating circular plate 5 is fixedly connected to the bottom end of the mounting base 6. A second motor 12 is fixedly connected to one side of the mounting frame 1, and the output end of the second motor 12 is fixedly connected to one end of a rotating rod 13 located on one side.

[0046] The first motor 4 drives the rotating disc 5 to rotate, and the rotating disc 5 drives multiple laser emitter bodies 7 to rotate through the mounting base 6, so that the multiple laser emitter bodies 7 can change the laser irradiation effect in different ways. The second motor 12 drives the laser lamp tube 2 to deflect through the rotating rod 13, so that the multiple laser emitter bodies 7 can irradiate in multiple directions, not limited to irradiation in a single direction, thus expanding its irradiation range. Specific Implementation Example 2:

[0048] Please see Figures 2-4 As shown, in a preferred embodiment, the insertion fastening mechanism 11 includes a pair of sliding magnet blocks 1101, both of which are slidably connected to the bottom end of the laser tube 2. One side of each sliding magnet block 1101 is provided with a fixed magnet block 1103 that attracts it. The bottom ends of each pair of sliding magnet blocks 1101 are fixedly connected to L-shaped blocks 1104, and the near ends of each pair of L-shaped blocks 1104 are fixedly connected to rectangular blocks 1105. The near ends of each pair of rectangular blocks 1105 are fixedly connected to insert blocks 1106. Both sides of the connecting sleeve block 9 are provided with a pair of slots 1108, and the insert blocks 1106 are located in the slots 1108.

[0049] In the specific implementation process, during the disassembly of the filter body 8, multiple pairs of sliding magnets 1101 are sequentially moved to slide away from each other and separate from the fixed magnet 1103. The L-shaped block 1104 and the rectangular block 1105 drive the insert 1106 to separate from the slot 1108, thus removing the limiting fixation of the connecting sleeve 9, so as to facilitate the subsequent disassembly and separation of the connecting sleeve 9. After the new filter body 8 is inserted into the round opening, multiple pairs of sliding magnets 1101 are sequentially moved to slide towards each other until they are attracted and fixed with the fixed magnet 1103. At this time, the insert 1106 is also inserted into the slot 1108 with the movement of the sliding magnets 1101 for limiting fixation. This strengthens the installation and fixation between the filter body 8 and the laser lamp tube 2, making it less likely for the filter body 8 to loosen and fall off under the vibration of the first motor 4 during operation, thus ensuring installation stability.

[0050] The bottom end of the laser tube 2 has multiple pairs of grooves 1102, and the sliding magnet block 1101 and the fixed magnet block 1103 are both located in the grooves 1102. The sliding magnet block 1101 is slidably connected to the grooves 1102, and the fixed magnet block 1103 is fixedly connected to the grooves 1102.

[0051] The groove 1102 guides and restricts the sliding magnet 1101 as it slides, and the fixed magnet 1103 is located in the groove 1102, attracting and fixing the sliding magnet 1101 as it slides close to the fixed magnet 1103, thus keeping it stable.

[0052] The outer wall of the insert 1106 is fitted with an anti-slip rubber pad 1107, and the outer wall of the anti-slip rubber pad 1107 is in contact with the inner wall of the slot 1108.

[0053] By setting the anti-slip rubber pad 1107, its surface anti-slip design can improve good friction, strengthen the contact and insertion with the inner wall of the slot 1108, and when the first motor 4 is working, the vibration generated by it is transmitted to the filter body 8 through the built-in straight plate 3. The anti-slip rubber pad 1107 absorbs and isolates the vibration, reducing the vibration impact of the first motor 4 during operation.

[0054] The circuits, electronic components, and chip modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

[0055] All standard parts used in the application documents can be purchased from the market. All components in this application document can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The electrical components mentioned in this document are all electrically connected to the external main controller and power supply, and the main controller is a conventional known device that can play a control role.

[0056] The working principle of this utility model is as follows:

[0057] When the filter body 8 needs to be disassembled and replaced during use, multiple pairs of sliding magnet blocks 1101 are sequentially moved to slide apart from the fixed magnet block 1103. The L-shaped block 1104 and rectangular block 1105 then drive the insert block 1106 to separate from the slot 1108, thus removing the limiting fixation of the connecting sleeve block 9. Next, multiple pairs of flipping pressure plates 1004 are sequentially flipped downwards by 90 degrees, causing the flipping pressure plates 1004 to drive a pair of movable protrusions 1005. The pair of movable protrusions 1005 first move along the round rod 1006 towards the flipping pressure plate 1004 under pressure, simultaneously compressing the spring 1008. This causes the pair of movable protrusions 1005 to move away from the pair of vertical limiting grooves 1007, and then flip from a horizontal state to a vertical state with the flipping pressure plate 1004. After the flipping is completed, the spring 1008... The elastic force extends to a pair of limiting grooves 1007 in the horizontal direction, engaging them to release the clamping limit of the flipping pressure plate 1004 on the connecting sleeve block 9. Then, the connecting sleeve block 9 is pulled downward to separate from the concave cylindrical block 1001, causing the filter body 8 to move downward until it separates from the laser tube 2 for disassembly. Next, the new filter body 8 is inserted into the round opening, and the connecting sleeve block 9 is driven to fit onto the concave cylindrical block 1001. Then, multiple pairs of flipping pressure plates 1004 are flipped to the horizontal state to clamp and limit the connecting sleeve block 9. Then, multiple pairs of sliding magnet blocks 1101 are slid towards each other until they are attracted and fixed with the fixed magnet block 1103. At this time, the insert block 1106 is also inserted into the slot 1108 along with the movement of the sliding magnet block 1101 for limiting and fixing, thereby realizing the replacement and installation of the filter body 8.
