[0044] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clear and obvious, the present application will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0045] The principles and structures of the present application will be described in detail below in combination with the drawings and embodiments.

[0046] In the air conditioner outdoor unit electrical box, the module pin on the mainboard which will emit heat will be exposed between the mainboard and the module body, when the air conditioner runs, the heat emitted by the module will attract insects to warm up, because the module pin is not insulated, the insects will cause the heat dissipation module to short circuit after crawling in, thereby causing the mainboard to be damaged and the air conditioner to be unable to work normally.

[0047] As Figure 1 , Figure 2 , Figure 3 Indicated, the utility model provides a kind of insect-proof box 2, and insect-proof box 2 main body is installed on the front of mainboard 1. Mainboard 1 is provided with a plurality of modules 3 with pin, these modules 3 will generate heat when running. To effectively manage the heat generated by module 3, heat generating module 3 can be covered with radiator 4 on the top surface. Insect-proof box 2 is set around the heat generating module 3 on mainboard 1, and the area around module 3 is enclosed by its structure, and the specific enclosed area is located between radiator 4 and mainboard 1, to form an isolated space.

[0048] The insect-proof box 2 surrounds the high-heat module 3 on the mainboard 1 by the surrounding structure, effectively isolates dust and insects and other pollutants in the external environment from entering the pin of module 3, which not only improves the protection performance of the equipment, but also ensures the normal operation of the heat dissipation system, and further ensures the long-term stable operation of module 3.

[0049] In specific embodiments, the insect-proof box 2 can specifically include a plurality of baffles, which are connected to surround the module 3, forming a closed barrier. The baffles are arranged around the four sides of the module 3, and are specifically arranged in the area between the edge of the module 3 and the radiator 4, corresponding to the position of the heat generating module 3 on the mainboard 1. The connection points between the baffles can be adjusted according to the shape and size of the module 3, i.e. the area surrounded is adjustable, suitable for heat generating modules 3 of different sizes, to ensure that the baffles are tightly fitted around the module 3, avoiding any gap that reduces the insect-proof effect. The arrangement of the baffles not only effectively blocks the entry of external dust and insects, but also further limits the flow of air around the module 3, ensuring that the area between the radiator 4 and the mainboard 1 is effectively isolated. Form a complete insect-proof structure.

[0050] As Figure 4 , 5, 6, in the first embodiment, the insect-proof box 2 includes a first baffle 51 and a second baffle 52, both of which are U-shaped and located on opposite sides of the heat-generating module 3 on the main board 1, such as the left and right sides or the front and back sides. The first baffle 51 and the second baffle 52 have a certain redundancy in space and their shapes match the layout of the module 3. The intermediate baffle 53 connected between the two end portions of the first baffle 51 and the second baffle 52 further encloses an adjustable closed area. Moreover, the area enclosed by the first baffle 51, the second baffle 52 and the intermediate baffle 53 can be adjusted according to the actual arrangement and size of the module 3 on the main board 1 to adapt to different shapes and sizes of the module 3 layout.

[0051] The U-shaped structure of the first baffle 51 and the second baffle 52 provides reliable support for the connection of the intermediate baffle 53, while blocking the entry of external pollutants. Through the adjustable structure, the insect-proof requirement is met, and the normal play of the heat dissipation performance is ensured.

[0052] As shown in Figure 5 , in a further embodiment, the first baffle 51 and the second baffle 52 are structurally identical and symmetrically arranged, both including an end plate 54 and a side plate 55 connected perpendicularly to both ends of the end plate 54, so that the whole is U-shaped, wherein the side plate 55 is internally provided with a hollow interlayer to form a slot 56. The opening direction of the slot 56 is towards the intermediate baffle 53, and both ends of the intermediate baffle 53 can be inserted into the slot 56, thereby blocking the gap between the first baffle 51 and the second baffle 52. Since the gap width between the first baffle 51 and the second baffle 52 is adjustable, by adjusting the depth of the intermediate baffle 53 inserted into the slot 56, the size of the area enclosed between the first baffle 51 and the second baffle 52 can be changed. This adjustable design makes the insect-proof box 2 able to flexibly adapt to the installation requirements of different modules 3, ensuring that the key areas around the module 3 are fully enclosed, while not affecting the normal heat dissipation and installation operation of the module 3. The structure of the end plate 54 and the side plate 55 on both sides provides stable support for the intermediate baffle 53, ensuring the overall sealing and protection performance of the insect-proof box 2.

[0053] As shown in Figure 8As shown, in the second embodiment, the insect-proof box 2 includes four L-shaped third baffles 57 distributed at the four opposite corners, and four intermediate baffles 53 connected between adjacent third baffles 57. Hollow interlayers are provided at both ends of the third baffles 57 to form slots 56. The two ends of the intermediate baffles 53 can be inserted into the slots 56 to block the gaps between adjacent third baffles 57. The four L-shaped third baffles 57 are respectively installed at the four opposite corners of the insect-proof box 2. The intermediate baffles 53 can be inserted into the slots 56 to form a tight connection with adjacent third baffles 57, thereby sealing the gaps between adjacent baffles 57 and ensuring the overall sealing and stability of the insect-proof box 2. The combination of the L-shaped third baffles 57 and the intermediate baffles 53 forms a multi-directional closed protective structure. The L-shaped design of the third baffles 57 not only provides good support performance but also facilitates the formation of stable connection points at the four corners of the insect-proof box 2. The intermediate baffle 53 is connected via slot 56, further strengthening the overall structure of the insect-proof box 2 and ensuring that it remains stable during installation, preventing deformation or loosening. The cooperation between the intermediate baffle 53 and slot 56 allows the insect-proof box 2 to be flexibly adjusted to accommodate different module 3 sizes and installation requirements, ensuring insect-proof effectiveness while improving installation convenience.

[0054] like Figure 7 As shown, preferably, the fit gap A between the width of the slot 56 and the thickness of the intermediate baffle 53 ranges from 1mm to 2mm, with the optimal fit gap being between 1.4-1.6mm. Ensuring a tight fit between the intermediate baffle 53 and the slot 56 guarantees the stability of the insect-proof box 2 while avoiding installation difficulties caused by excessive tightness. The fit gap range of 1mm to 2mm between the width of the slot 56 and the thickness of the intermediate baffle 53 can meet different installation requirements.

[0055] In practical applications, the optimal fitting clearance is between 1.4 and 1.6 mm. This fitting clearance not only ensures tight contact between the intermediate baffle 53 and the slot 56, reducing gaps and potential defects, but also buffers minor deviations that may occur during installation. By precisely controlling the range of the fitting clearance, the overall performance and reliability of the insect-proof box 2 are further improved.

[0056] like Figure 1As shown, in specific embodiments, the end plates 54 are designed to extend beyond the bottom surface of the heat sink 4, such that the side plates 55 at both ends of the end plates 54 are located outside the coverage of the heat sink 4. Specifically, the end plates 54 extend beyond the bottom surface of the heat sink 4 by a length sufficient to support the side plates 55 in a position outside the coverage of the heat sink 4, with a gap maintained between the side plates 55 and the heat sink 4, and the gap does not exceed 2 mm. Avoiding interference between the side plates 55 and the heat sink 4 allows the middle baffle 53 to be directly inserted from above and downwards. The small gap between the side plates 55 and the heat sink 4 also helps to prevent tiny particles or insects from entering the area around the module 3 from the gap, further improving the protection performance of the insect-proof box 2. In addition, this structural design also ensures that the heat of the module 3 can be efficiently dissipated through the heat sink 4.

[0057] As shown in FIG. 1, Figure 10 , 11 In specific embodiments, the insect-proof box 2 is provided with a plurality of heat dissipation holes 22, which can be located on the side plates 55. The heat dissipation holes 22 provide a heat dissipation channel while not affecting the protection function of the insect-proof box 2. As shown in FIG. 1, Figure 4 The heat dissipation holes 22 can be provided on the side plates 55 and can be circular, oval or other suitable shapes, and are uniformly distributed to avoid local overcrowding or sparseness. The size and number of heat dissipation holes 22 can be adjusted according to specific requirements to maximize the heat dissipation efficiency. The design of the heat dissipation holes 22 not only considers the rapid dissipation of heat, but also considers the sealing of the insect-proof box 2 to prevent insects from invading through the heat dissipation holes 22. By providing heat dissipation holes 22 on the side plates 55, the insect-proof box 2 can effectively dissipate heat during operation and avoid affecting the performance of the module 3 due to temperature rise.

[0058] Further, the heat dissipation holes 22 have a pore size range of 1 mm to 3 mm. This pore size range not only ensures effective heat dissipation, but also plays a role in dust and insect prevention, preventing external particulate matter and insects from entering the module 3 area through the heat dissipation holes 22. The optimal pore size range is 1.3 mm to 2 mm. This range can achieve the best balance between heat dissipation efficiency and protection performance: a smaller pore size can more effectively block the entry of small particles and insects, while a larger pore size can provide better air flow, thereby improving heat dissipation efficiency. According to actual needs and environmental conditions, the pore size of the heat dissipation holes 22 can be selectively optimized to adapt to different use scenarios.

[0059] As shown in FIG. 1, Figure 2 , 9As shown, in specific embodiments, the bottom surface of the insect prevention box 2 is provided with a plurality of latches 21, and the main plate 1 is correspondingly provided with a plurality of sockets 11 for the insertion of the latches 21. The latch connection design facilitates the installation and disassembly of the insect prevention box 2, improves the convenience of use, and also ensures the stability of the insect prevention box 2 in various working environments. The latches 21 can be symmetrically arranged, for example, distributed at opposite positions of the bottom surface of the insect prevention box 2 (the bottom surface of the two end plates 54), to prevent the insect prevention box 2 from loosening due to vibration or other external forces during operation. The latch connection method not only improves the convenience of installation of the insect prevention box 2, but also enhances the protection performance of the equipment, ensuring the dustproof and insect prevention effect of the area around the module 3, and providing protection for the long-term stable operation of the equipment.

[0060] Preferably, after the latch 21 is inserted into the socket 11, the side edge of the latch 21 in the width direction has a cooperation gap with the socket 11 in the range of 0.2mm to 2mm, and the optimal cooperation gap is between 0.5mm and 0.8mm. The cooperation gap between the side edge of the latch 21 in the width direction and the socket 11 is controlled in the range of 0.2mm to 2mm through precise design, to adapt to different installation requirements and processing tolerances. A smaller cooperation gap (such as 0.2mm) can ensure the close cooperation between the latch 21 and the socket 11, preventing loosening problems caused by unstable connection; a larger cooperation gap (such as 2mm) can to some extent buffer the slight deviation that may occur during installation, improving the convenience of installation.

[0061] The optimal cooperation gap is between 0.5mm and 0.8mm. The cooperation gap in this range can balance stability and installation flexibility, ensuring stable connection between the latch 21 and the socket 11, and avoiding installation difficulties caused by too tight cooperation. In addition, the control of the cooperation gap can effectively prevent insects from invading through the large gap, and through appropriate gap design, the connection between the insect prevention box 2 and the main plate 1 is more tight, further enhancing the closure and protection effect of the overall structure.

[0062] The insect prevention box can be applied to an electrical box, for example, an electrical box component of an outdoor air conditioner, or an electrical box of other equipment.

[0063] The utility model also provides an electrical box, which comprises a main plate, a module arranged on the main plate to generate heat, a heat dissipation module corresponding to the module, and an insect prevention box, wherein the insect prevention box encloses the area between the heat sink and the main plate around the module. By surrounding the high-heat module 3 on the main plate 1, the dust and insects in the external environment are effectively prevented from entering the pins of the module 3, which not only improves the protection performance of the equipment, but also ensures the normal operation of the heat dissipation system, thereby ensuring the long-term stable operation of the module 3.

[0064] The utility model also provides a kind of air conditioner, and its air conditioner outdoor unit includes above-mentioned electric appliance box. The electric appliance box can improve its stability of operation by preventing insect box, so that air conditioner outdoor unit and its whole body can be stably operated.
