[0049] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them.

[0050] In the description of this embodiment, the terms "upper", "lower", "left", "right" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0051] This embodiment provides a heat dissipation device, which is used to dissipate heat from a heat generating device (not shown). Figure 1 and Figure 2 As shown, the heat dissipation device includes a mesh cover assembly 10 and a fan 20. The mesh cover assembly 10 covers the heating device and is provided with an air outlet area 12. The air outlet area 12 has multiple air outlet holes 121 to ensure that the heat is dissipated to the outside air. The fan 20 is installed on the mesh cover assembly 10 and is located on the inner side of the mesh cover assembly 10. The fan 20 can increase the air flow speed around the heating device and enhance the heat dissipation effect.

[0052] Among them, due to the changeable working environment, after the mesh cover assembly 10 has been working for a period of time, the air outlet area 12 will be covered with debris, which may be dust, dead leaves or catkins, etc. If it is not cleaned in time, it will affect the heat dissipation effect. In the prior art, a cleaning member 32 is set in the air outlet area 12, and a clutch is set between the fan 20 and the cleaning member 32, so that when the fan 20 is in the back-blowing state, the cleaning member 32 is driven to realize the self-cleaning function of the mesh cover assembly 10. The structure of this method is relatively complex, and the clutch needs to share the trigger signal with the fan back-blowing, and the added clutch reduces the reliability of the system, which is not easy to replace and repair. There are also two ways to achieve good results in achieving self-cleaning of the mesh cover assembly 10 by adding a spray device and adding an air jet device, but the application cost is high and it is not suitable for the transformation of old cabinets.

[0053] In order to solve the above problems, Figure 1-Figure 5 As shown, the heat dissipation device of this embodiment also includes a cleaning component 30 and a one-way transmission component 40, and the fan 20 can rotate forward or reverse; the one-way transmission component 40 includes a one-way bearing 41 and a bearing seat 42 fixedly mounted on the outer ring of the one-way bearing 41, and the fan 20 is coaxially connected to the inner ring of the one-way bearing 41; the cleaning component 30 is coaxially connected to the bearing seat 42, and the cleaning component 30 can rotate in close contact with the air outlet area 12.

[0054] In the above-mentioned heat dissipation device, when the fan 20 rotates forward, the wind blows toward the heating element, the outer ring of the one-way bearing 41 does not rotate with the rotation of the fan 20, and the cleaning member 32 remains stationary; after working for a period of time, the fan 20 reverses to drive the one-way bearing 41 to rotate, and the one-way bearing 41 drives the bearing seat 42 to rotate, thereby driving the cleaning component 30 to rotate with the fan 20 to achieve the effect of cleaning the surface of the mesh cover component 10. The heat dissipation device can realize regular cleaning of the mesh cover component 10, and compared with the clutch, the structure is more streamlined and the reliability is high.

[0055] The structure of the one-way bearing 41 is prior art and will not be described in detail here.

[0056] It should be noted that a mesh cover assembly 10 may be provided with an air outlet area 12, or Figure 1 In this way, multiple air outlet areas 12 are arranged in an array and are flexibly arranged according to the arrangement of the heating devices. The fan 20, the one-way transmission component 40 and the cleaning component 30 can be arranged in a one-to-one correspondence with the air outlet area 12, and no limitation is made here.

[0057] Alternatively, if Figure 3As shown, the cleaning assembly 30 includes a first rotating shaft 31 and a cleaning member 32. The first rotating shaft 31 is pivoted to the air outlet area 12 and is coaxially connected to the bearing seat 42. The first rotating shaft 31 is connected to the cleaning member 32 and can drive the cleaning member 32 to rotate. Through the above arrangement, when the cleaning member 32 rotates, the cleaning member 32 can effectively clean the air outlet area 12. Optionally, the cleaning member 32 can be a brush or a soft film, etc., which is not limited here.

[0058] Alternatively, if Figure 5 As shown, the second rotating shaft 21 is protruding from the center of the fan 20, and the inner ring of the one-way bearing 41 is sleeved on the second rotating shaft 21. Through the above arrangement, the fan 20 drives the inner ring of the one-way bearing 41 to rotate.

[0059] Furthermore, if Figure 3 and Figure 5 As shown, the cleaning assembly 30 includes a first rotating shaft 31 and a cleaning member 32. The first rotating shaft 31 is pivoted to the air outlet area 12 and is coaxially connected to the bearing seat 42. The first rotating shaft 31 is connected to the cleaning member 32 and can drive the cleaning member 32 to rotate. The second rotating shaft 21 is convexly arranged at the center of the fan 20, and the inner ring sleeve of the one-way bearing 41 is arranged on the second rotating shaft 21. Through the above arrangement, the second rotating shaft 21 realizes the connection between the fan 20 and the one-way bearing 41. The forward rotation of the fan 20 drives the second rotating shaft 21 to rotate forward, the one-way bearing 41 does not move, and the fan 20 only blows air. When the fan 20 reverses, it drives the second rotating shaft 21 to reverse, and the one-way bearing 41 rotates accordingly, driving the first rotating shaft 31 to rotate, and then driving the cleaning member 32 to clean the air outlet area 12.

[0060] Alternatively, if Figure 3 As shown, the bearing seat 42 is provided with a plug-in groove 421, and the first rotating shaft 31 is provided with a plug-in protrusion 311, and the plug-in protrusion 311 is plugged into the plug-in groove 421. Through the above arrangement, during the installation process, as long as the plug-in protrusion 311 is inserted into the plug-in groove 421, when the bearing seat 42 rotates, the plug-in protrusion 311 can be driven to rotate, the installation method is simple, and the transmission structure is reliable. In other embodiments, the plug-in protrusion 311 can also be provided on the bearing seat 42, and the plug-in groove 421 can be provided on the first rotating shaft 31, and this effect can also be achieved, which is not limited here.

[0061] Optionally, the plug-in groove 421 is a non-circular groove, so that when there is a gap between the plug-in protrusion 311 and the plug-in groove 421, the bearing seat 42 can still drive the first rotating shaft 31 to rotate. During the installation process, it only needs to be aligned and inserted, and there is no need to ensure an interference fit between the two, that is, there is no need to knock hard to ensure that the plug-in protrusion 311 is embedded in the plug-in groove 421. When the plug-in groove 421 and the plug-in protrusion 311 have a gap fit, the first rotating shaft 31 can also rotate with the bearing seat 42, which further simplifies the installation method.

[0062] Optionally, in the present embodiment, the plug-in slot 421 is a square slot. In other embodiments, the plug-in slot 421 may also be in a triangular, polygonal, elliptical or other shape, which is not limited here.

[0063] Alternatively, if Figure 3 As shown, a mounting hole 122 is provided in the middle of the air outlet area 12, and the air outlet area 12 is connected to a limiting flange 123, and the limiting flange 123 covers at least part of the mounting hole 122; the cleaning component 30 also includes a bearing 33, the bearing 33 is installed in the mounting hole 122 and abuts against the limiting flange 123, and the inner ring of the bearing 33 is sleeved on the first rotating shaft 31. Through the above arrangement, when the bearing 33 is installed, the limiting flange 123 can play a role of circumferential limiting. Preferably, the limiting flange 123 is arranged at the end of the mounting hole 122 away from the fan 20, that is, the limiting flange 123 is on the outside of the bearing 33, has a certain dustproof effect, and ensures the stability of the bearing 33 for long-term use.

[0064] Alternatively, if Figure 3 As shown, the hole wall of the mounting hole 122 extends along the axial direction of the first rotating shaft 31, and one end of the hole wall of the mounting hole 122 is connected to a limiting flange 123. The above arrangement makes the length of the hole wall of the mounting hole 122 longer, matching the length of the outer ring of the one-way bearing 41, increasing the interference area between the two, and improving the stability of the installation. At the same time, the connection position setting of the limiting flange 123 makes the air outlet area 12 easier to form.

[0065] Alternatively, if Figure 3 As shown, a polygonal prism 312 is disposed at the outward end of the first rotating shaft 31, and a first through-hole (coinciding with the polygonal prism 312, not marked) is provided on the cleaning member 32, the first through-hole is adapted to the shape of the cross section of the polygonal prism 312, and the polygonal prism 312 is plugged into the first through-hole. Thus, when the first rotating shaft 31 rotates, the cleaning member 32 can be driven to rotate to achieve the effect of cleaning the air outlet area 12. In this embodiment, the polygonal prism 312 is a quadrilateral prism, and in other embodiments, it can also be a triangular prism or a prism with more sides, which is not limited here.

[0066] Alternatively, if Figure 3 and Figure 7 As shown, the cleaning assembly 30 further includes a locking member 34 and a limiting member 35. The limiting member 35 abuts against the end surface of the polygonal prism 312 to limit the position of the cleaning member 32 in the axial direction of the first rotating shaft 31. The locking member 34 passes through the limiting member 35 and is locked and fixed with the polygonal prism 312. Through the above arrangement, the limiting member 35 and the locking member 34 are used together to achieve the axial limitation of the cleaning member 32.

[0067] Alternatively, if Figure 3As shown, the first rotating shaft 31 also includes a first shaft portion 313, and the above-mentioned polygonal prism 312 is arranged at the outward end of the first shaft portion 313, and a limiting surface is formed between the two. The bearing 33 is sleeved on the first shaft portion 313, and the side of the cleaning member 32 facing away from the locking member 34 abuts against the limiting surface, and the limiting surface is on the outside of the limiting flange 123. According to this arrangement, both sides of the cleaning member 32 are limited, and the cleaning wall of the cleaning member 32 is prevented from scratching the structure of the air outlet area 12.

[0068] Alternatively, if Figure 3 As shown, the first rotating shaft 31 also includes a limiting protrusion 315, which is annular and located at the end of the first shaft portion 313 away from the polygonal prism 312. The setting of the limiting protrusion 315 can ensure that when the first rotating shaft 31 is installed on the bearing 33, the end face of the limiting protrusion 315 abuts against the end face of the bearing 33, and the installation position is more accurate, thereby ensuring the accuracy of the position of the limiting surface.

[0069] Alternatively, if Figure 3 , Figure 6 and Figure 7 As shown, a cleaning member 32 is provided on both the inner and outer sides of the air outlet area 12 to improve the cleaning effect. The aforementioned cleaning member 32 refers to the installation and limiting method of the outer cleaning member 32. For the inner cleaning member 32, as shown in FIG. Figure 3 As shown, the inner cleaning member 32 also has a first through hole, and the first through hole is adapted to the shape of the plug-in protrusion 311 , so that when the cleaning member 32 is worn out, it is more convenient to replace it.

[0070] Alternatively, if Figure 3 As shown, the rotating shaft also includes a second shaft portion 314, and the two ends of the second shaft portion 314 are respectively connected to the limiting protrusion 315 and the plug-in protrusion 311, and the end surface of the plug-in protrusion 311 and the second shaft portion 314 form a limiting surface, so that the end surface of the inner cleaning member 32 can abut against the limiting surface, thereby limiting the axial movement of the inner cleaning member 32.

[0071] Alternatively, if Figure 8 and Fig. 9As shown, the mesh cover assembly 10 includes a mesh cover body 11 and a mesh plate 13. The mesh cover body 11 covers the heating device, and the mesh cover body 11 has a through hole 112; the mesh plate 13 is detachably connected to the mesh cover body 11 and covers the through hole 112, and the air outlet area 12 is arranged on the mesh plate 13; the cleaning component 30 is plugged into the bearing seat 42. Specifically, the first rotating shaft 31 is plugged into the bearing seat 42. Through the above arrangement, when repairing or replacing parts, since the first rotating shaft 31 is plugged into the bearing seat 42, the mesh plate 13 can be removed by directly pulling it outward. When the mesh plate 13 is removed, the cleaning component 30 is also removed, which also facilitates the replacement of the cleaning component 30. Among them, the detachable connection between the mesh plate 13 and the mesh cover body 11 can be a snap connection, a threaded connection, etc., which is not limited here. It can be understood that in this embodiment, the mesh plate 13 is also the air outlet area 12 mentioned above. In other embodiments, the mesh cover body 11 is not provided with the through hole 112, the air outlet area 12 is directly provided on the mesh cover body 11, and the air outlet hole 121 is also provided on the mesh cover body 11, which is not limited here.

[0072] Alternatively, if Figure 8 and Fig. 9 As shown, the fan 20 is mounted on the mesh cover body 11 through the fan mounting member 50. The fan mounting member 50 is U-shaped, and the two mounting ends of the fan mounting member 50 are respectively fitted with the opposite side surfaces of the mesh cover body 11 and fixed by a first fixing member, which can be a screw, a rivet or an adhesive. The mounting flange 22 of the fan 20 is fitted with the large surface of the fan mounting member 50 and fixed by a second fixing member, which can be a screw, a rivet or an adhesive.

[0073] Alternatively, if Figure 6 , Fig.10 and Fig.11 As shown, at least two clamping members 111 are convexly provided on the mesh cover body 11, and a clamping hole 131 is provided on the mesh plate 13. The clamping members 111 are clamped and matched with the clamping holes 131. After the mesh plate 13 moves along a set direction, the clamping members 111 are separated from the clamping holes 131. Through the above arrangement, when installing the mesh plate 13, the clamping holes 131 and the clamping members 111 can be correspondingly clamped. When the mesh plate 13 needs to be disassembled, the clamping members 111 and the clamping holes 131 can be separated by moving along a set direction, which is convenient for assembly and disassembly.

[0074] In this embodiment, Figure 6 , Fig.10 and Fig.11As shown, the clamping member 111 is constructed as a T-shaped protrusion, at least two T-shaped protrusions are arranged circumferentially around the through hole 112, the clamping hole 131 is set one by one with the T-shaped protrusion, the clamping hole 131 includes a second through hole 1311 and a sliding hole 1312 connected, the large end of the T-shaped protrusion can pass through the second through hole 1311, and the small diameter part of the T-shaped protrusion can slide along the sliding hole 1312 to the end of the sliding hole 1312 away from the second through hole 1311. First, the second through hole 1311 is matched with the T-shaped protrusion, so that the T-shaped protrusion is inserted into the second through hole 1311, and then along Fig.10 Rotate the mesh plate 13 in the direction of the middle arrow so that the T-shaped protrusion slides relative to the sliding hole 1312. When the T-shaped protrusion abuts against the end of the sliding hole 1312 away from the second perforation 1311, it means that the mesh plate 13 is installed in place. When the mesh plate 13 needs to be removed, just reverse it in the direction of the arrow. This disassembly method can achieve quick disassembly and assembly of the mesh plate 13.

[0075] In other embodiments, the direction of the snap-in hole 131 may extend in the horizontal or vertical direction. When removing, the snap-in hole 131 can be disengaged from the snap-in component 111 by moving in the horizontal or vertical direction. This is not limited here.
