Therefore, they should not be construed as limitations on this utility model. Furthermore, "first" and "second" are only for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "multiple" means two or more.

[0030] Please see Figures 1 to 8As shown, this utility model provides a projection lamp, including a housing 1, a mounting bracket 2, a projector 3, a cover 4, and fasteners 5. The mounting bracket 2 is mounted on the housing 1 and is used to install on a wall. The bottom of the housing 1 has a first opening 11, and a flange 12 is provided on the first opening 11. The cross-section of the flange 12 is an "L" shaped structure. A base plate 13 is provided inside the housing 1. The projector 3 is mounted on the base plate 13. The cover 4 covers the first opening 11 and abuts against the bottom of the flange 12. The cover 4 is detachably connected to the housing 1 by a number of fasteners 5.

[0031] During disassembly, simply open the multiple fasteners 5 to remove the cover 4 from the housing 1. During installation, the "L"-shaped flange 12 defines the installation position of the cover 4, and then the multiple fasteners 5 are fastened to secure the cover 4. Throughout the process, the cover 4 can be quickly installed and removed to facilitate internal maintenance and repair of the projection lamp.

[0032] In a preferred embodiment, see [reference] Figure 1 , 2 The fastener 5 is a tower fastener. The tower fastener includes a hook fixed to the cover 4 and a latch fixed to the outer shell. By operating a lever on the latch, the hanging ring on the latch can be hooked onto the hook, or the hanging ring can be disengaged from the hook, causing the tower fastener to close or separate, thereby achieving quick assembly and disassembly of the cover 4. In this embodiment, preferably, there are four fasteners 5, symmetrically arranged, to improve the stability of the cover 4 installation.

[0033] In a preferred embodiment, see [reference] Figure 3 , 5 The bottom of the flange 12 is provided with a silicone strip 14, the cross-section of which is a "U-shaped structure". The silicone strip 14 abuts against the inner wall of the cover 4. By setting the silicone strip 14, the sealing between the cover 4 and the housing 1 is improved, thereby playing a role in dust prevention.

[0034] In a preferred embodiment, see [reference] Figure 3 , 5 The outer side of the flange 12 is provided with several positioning brackets 15, which are used to define the installation position of the cover 4. Specifically, the positioning bracket 15 has a "C" shaped structure, with its top edge fixed to the horizontal plane of the flange 12, and its sides set away from the vertical plane of the flange 12 and inclined. The multiple inclined sides guide the cover 4, further facilitating the installation of the cover 4.

[0035] In this embodiment, the housing 1 is a roughly rectangular structure, and the flange 12 has four sides. Each side is provided with a positioning bracket 15 to limit the position of the cover 4 in the horizontal direction, so as to prevent the cover 4 from swaying left and right or back and forth, thereby ensuring the stability of the cover 4 during installation.

[0036] In a preferred embodiment, see [reference] Figure 1 , 3 The top of the housing 1 is equipped with a lifting ring 16, which allows the housing 1 to be lifted so that the mounting bracket 2 can be fixed to the wall. The cover 4 is equipped with a hanging rope 41, which allows it to be suspended from the lifting ring 16. The removed cover 4 can be suspended from the lifting ring 16. Compared with existing technologies, there is no need to consider how to place the cover 4 after removal, and the cover 4 will not fall due to accidental contact.

[0037] In a preferred embodiment, see [reference] Figure 3 It also includes a heat dissipation bracket 6, a controller 7 and a dust cover 61 both mounted on the heat dissipation bracket 6. The heat dissipation bracket 6 is mounted on the base plate 13, and the controller 7 is located inside the dust cover 61. The controller 7 is electrically connected to the projector 3. By setting up the heat dissipation bracket 6 and the dust cover 61, the controller 7 is protected from dust and water.

[0038] Preferably, both the heat dissipation bracket 6 and the dust cover 61 are made of materials with high thermal conductivity to improve the heat dissipation efficiency of the controller 7.

[0039] In addition to installing controller 7, the above structure can also be used to install other control units, and its specific use is not limited here.

[0040] Furthermore, the heat dissipation bracket 6 has a plurality of heat dissipation holes 62. Through the above-mentioned arrangement, the contact area between the heat dissipation bracket 6 and the air is increased, thereby improving the heat dissipation efficiency.

[0041] See Figure 2 , 4 To improve the heat dissipation efficiency inside the casing 1, the top of the casing 1 has an air inlet 17 and an air outlet 18. Both the air inlet 17 and the air outlet 18 are equipped with filters 8. The base plate 13 is equipped with several intake fans 131 and exhaust fans 132, with the intake fans 131 located below the air inlet 17 and the exhaust fans 132 located below the air outlet 18. Specifically, the base plate 13 is horizontally arranged inside the casing 1, and the base plate 13 is equipped with several ventilation holes 133. The multiple holes 133 correspond to the positions of the intake fans 131 and the exhaust fans 132, so that the outside air, after being filtered by the filters 8, enters the casing 1 through the air inlet 17, passes through the holes 133 corresponding to the intake fans 131, the projector 3, and the holes 133 corresponding to the exhaust fans 132, and finally exits from the air outlet 18, thereby carrying away the heat generated by the projector 3 and achieving heat dissipation for the projector 3.

[0042] Preferably, the air inlet 17 and the air outlet 18 are symmetrically arranged, so that the air intake fan 131 and the air outlet fan 132 are symmetrically arranged on both sides of the projector 3, and the introduced outside air can flow through the entire projector 3, which plays a good role in heat dissipation for the projector 3.

[0043] As described above, the filter 8 is used to filter dust particles in the air, preventing dust particles from accumulating inside the casing 1 and affecting the normal operation of the projector 3. However, in actual use, the filter 8 needs to be cleaned regularly to prevent excessive dust accumulation from affecting heat dissipation.

[0044] Specifically, see Figure 6 , 7 The filter screen 8 includes a housing 81 and a filter screen assembly 82. The top of the housing 81 is provided with a receiving cavity 811 and a second opening 812 penetrating the receiving cavity 811. A third opening 813 is provided on one side of the receiving cavity 811. The filter screen assembly 82 is disposed in the receiving cavity 811. The filter screen assembly 82 has a positioning hole 821. A first screw 83 is screwed into the receiving cavity 811. The first screw 83 can be inserted into the positioning hole 821.

[0045] During cleaning, the first screw 83 is unscrewed a short distance to disengage it from the positioning hole 821. Then, the filter assembly 82 is pulled outward along the direction of the third opening 813 to disassemble it. After cleaning the filter assembly 82, it is inserted directly into the receiving cavity 811 through the third opening 813. Finally, the first screw 83 is screwed in so that it is inserted into the positioning hole 821 to complete the installation of the filter assembly 82. The operation is simple and convenient for users to clean the filter assembly 82 regularly.

[0046] Preferably, the first screw 83 is a hand-tightening screw for easy user operation.

[0047] Further, see Figure 6 The filter assembly 82 includes a first pad 822, a filter 823, and a second pad 824 stacked sequentially. The first pad 822 is connected to the second pad 824 by several second screws 825. Both the first pad 822 and the second pad 824 have several through holes 133 arranged in a matrix. The first pad 822 and the second pad 824 are used to install the filter 823. The first pad 822 and the second pad 824 have multiple vent holes 826 for ventilation, and ribs 8261 formed between adjacent vent holes 826 further stabilize and support the filter 823, ensuring it remains flat. To clean the filter assembly 82, the multiple second screws 825 are removed sequentially, separating the first pad 822 and the second pad 824, allowing the filter 823 to be removed for cleaning or replacement.

[0048] It should be noted that the second opening 812 is provided with two parallel support frames 8111, and the two support frames 8111 and the three sides of the top of the housing 81 form a receiving cavity 811. The support frames 8111 provide support and limit the filter assembly 82, so that the filter assembly 82 can be stably installed in the receiving cavity 811.

[0049] In a preferred embodiment, the inner wall of the housing 81 is provided with a plurality of equally spaced grilles 814, and the plurality of grilles 814 are inclined. Figure 8 As shown, multiple grilles 814 are arranged along the length of the housing 81. The multiple inclined grilles 814 can guide airflow and prevent it from blowing randomly, thus ensuring the heat dissipation efficiency of the projection lamp. In addition, the inclined grilles 814 can also prevent dust. Tiny dust particles passing through the filter assembly 82 fall from top to bottom onto the upper surface of the grilles 814. The tiny dust particles are blocked by the grilles 814 and adhere to the upper surface of the grilles 814, thus preventing the tiny dust particles from directly entering the interior of the projector 3.

[0050] It is understood that those skilled in the art can make equivalent substitutions or changes based on the technical solution and inventive concept of this utility model, and all such substitutions or changes should fall within the protection scope of the appended claims of this utility model.
