Abstract
Description
Technical Field
[0001] This utility model relates to the field of car wash equipment technology, and in particular to a heat dissipation structure and a cleaning device. Background Technology
[0002] Cars are one of the main means of transportation used by people. After prolonged use, cars need to be washed regularly to keep them clean. To thoroughly remove debris and mud trapped in crevices, specialized cleaning devices, such as car wash water guns, are usually used. These devices typically contain components such as motors and water pumps. The water pump draws water into the cleaning device through the inlet pipe, and then the motor pressurizes the water flow and sprays it out of the outlet. The pressurized water effectively removes debris from the car's surface, thoroughly cleaning the vehicle.
[0003] When washing vehicles, the washing equipment is typically used for extended periods. During this time, the motor, water pump, and other internal components generate significant heat. To prevent overheating damage, ventilation holes are often installed in the washing equipment's casing. However, these ventilation holes are usually through-holes connecting the outside to the inside of the casing. While cooling is being done, dust, moisture, and other impurities from the outside can also enter the casing through these holes. Dust can then adhere to the motor and other components, hindering heat dissipation and potentially causing overheating damage. Furthermore, the large amount of moisture entering the casing can damage the electrical system, rendering the washing equipment unusable. Utility Model Content

[0043] Example 1
[0044] This embodiment provides a heat dissipation structure, such as Figures 1 to 7 As shown, by setting this heat dissipation structure, the cleaning device 100 can effectively prevent dust, water vapor and other impurities from entering the interior of the cleaning device 100, avoid damage to components and extend the service life of the cleaning device 100.
[0045] like Figures 1 to 4 As shown, the heat dissipation structure of the cleaning device includes a housing 1, a shielding component 21, and a heating element.
[0046] The housing 1 is provided with a receiving cavity 11 and a mounting part 12. The mounting part 12 is recessed from the outer surface of the housing to form an inner cavity; the inner cavity of the mounting part 12 communicates with the receiving cavity 11.
[0047] The heating element is housed in the receiving cavity 11;
[0048] The shielding member 21 is at least partially located in the inner cavity of the mounting part 12 and is limitedly connected to the mounting part 12; at least a portion of the outer wall surface of the shielding member 21 is spaced apart from the wall surface corresponding to the inner cavity of the mounting part 12, and the space between the at least a portion of the outer wall surface of the shielding member 21 and the wall surface corresponding to the inner cavity of the mounting part 12 forms a first heat dissipation channel, which is connected to the inner cavity of the mounting part 12. At this time, the first heat dissipation channel is the first heat dissipation channel 24.
[0049] In this embodiment, the shielding member 21 may be completely located in the inner cavity of the mounting part 12, or it may be partially located in the inner cavity, with another part protruding outward relative to the inner cavity of the mounting part 12. The shielding member 21 may have all its outer surfaces spaced from the inner cavity, or the shielding member 21 may be attached to the inner cavity on one or more sides, with the remaining outer surfaces spaced from the inner cavity.
[0050] In this embodiment, the mounting part 12 is a through hole, and the cavity of the through hole is the inner cavity of the mounting part 12.
[0051] like Figure 1 , Figure 2 and Figure 5 As shown, the lower end of the shielding member 21 is provided with a shielding flange 23. The shielding member 21 can be embedded in the through hole, and the shielding flange 23 is located in the receiving cavity 11.
[0052] When the cleaning device 100 is used to clean a vehicle, the heating element inside the cleaning device 100 will generate a large amount of heat during use. At this time, the heat of the heating element can be dissipated to the outside through the receiving cavity 11 and the first heat dissipation channel 24, thereby meeting the heat dissipation requirements inside the cleaning device 100. At the same time, since the shielding member 21 is located in the inner cavity, the shielding member 21 can shield the inner cavity along the axial direction, which can effectively prevent a large amount of dust, water vapor and other impurities from entering the cleaning device 100 through the inner cavity, avoid damage to components and extend the service life of the cleaning device 100.
[0053] Optionally, the cross-sectional area of the shielding member 21 is smaller than the shielding cross-sectional area of the through hole, and the cross-sectional area of the shielding flange 23 is greater than or equal to the cross-sectional area of the through hole. When the shielding member 21 is embedded in the through hole, the shielding flange 23 is located in the receiving cavity 11. By setting the cross-sectional area of the shielding member 21 to be smaller than the cross-sectional area of the through hole, and the cross-sectional area of the shielding flange 23 to be greater than or equal to the cross-sectional area of the through hole, the shielding member 21 and the shielding flange 23 along the axial direction of the through hole can completely cover and shield the through hole, which can prevent a large amount of dust, water vapor and other impurities from entering the cleaning device 100. At the same time, there will be a gap between the outer wall of the shielding flange 23 and the side wall of the through hole, so that the receiving cavity 11 can communicate with the outside through the gap, which can meet the heat dissipation requirements of the cleaning device 100.
[0054] In this embodiment, the cross-sectional area of the blocking flange 23 is equal to the cross-sectional area of the through hole. In other embodiments, the cross-sectional area of the blocking flange 23 may be set to be larger than the cross-sectional area of the through hole, depending on actual needs; this is not limited here.
[0055] Optionally, a locking member 3 is provided within the receiving cavity 11. Two stop plates 4 are spaced apart on the side wall of the locking member 3, forming an insertion groove 31 with the locking member 3. The heat dissipation structure also includes an insertion member 22, which is connected below the shielding flange 23. The insertion member 22 can penetrate the through hole and be inserted into the insertion groove 31. When it is necessary to shield the through hole, the insertion member 22 is inserted through the through hole into the insertion groove 31, so that the shielding flange 23 connected to the insertion member 22 is located within the receiving cavity 11, and the shielding member 21 is embedded within the through hole. The structure is simple and easy to operate.
[0056] Optionally, such as Figures 5 to 7 As shown, the heat dissipation structure also includes a second insertion member 25, which is connected to the lower part of the shielding flange 23 and spaced apart from the first insertion member 22. A second locking member 25 is also provided within the receiving cavity 11. Two stop plates 26 are spaced apart on the side wall of the second locking member 25, and the two stop plates 26 and the second locking member 25 form an insertion groove 251. For example... Figure 3 and Figure 6As shown, the openings of the second insertion slot 51 and the first insertion slot 31 are both located on opposite sides of each other, and the second insertion piece 25 can pass through the through hole and be inserted into the second insertion slot 51.
[0057] When the through hole is blocked, insert 22 and insert 25 are simultaneously inserted through the through hole, with insert 22 inserted into insert slot 31 and insert 25 inserted into insert slot 51. By setting insert 25 and insert slot 51, the connection nodes between the blocking member 21 and the housing 1 are increased, thereby improving the connection stability between the two. Increasing the connection nodes also helps ensure the proper alignment of the blocking member 21, making its positioning more accurate and installation easier. Furthermore, the slot openings of insert slot 51 and insert slot 31 are both located on opposite sides, further improving the stability and rigidity of the connection between the blocking member 21 and the housing 1, which is beneficial for force balance.
[0058] Optionally, such as Figure 4 , Figure 5 and Figure 7 As shown, both insertion part 22 and insertion part 25 have hook parts 221 at their lower ends. Limiting protrusions 7 are provided on the inner walls of insertion slot 31 and insertion slot 25, and the hook parts 221 can hook onto the end face of the limiting protrusion 7 facing away from the shielding part 21. By setting the hook parts 221 and the limiting protrusions 7 to work together, the connection strength between the shielding part 21 and the housing 1 can be further strengthened, enhancing the stability of the overall structure and preventing the shielding part 21 from shifting. This ensures the shielding effect on the through hole along the direction perpendicular to the through hole, preventing a large amount of dust and moisture from entering the receiving cavity 11 due to the loss of shielding, avoiding damage to components, and extending the service life of the cleaning device 100.
[0059] like Figure 4 , Figure 5 and Figure 7 As shown, a guide slope 71 is provided on the end face of the limiting protrusion 7 facing the blocking member 21. The guide slope 71 in the insertion slot 31 gradually moves away from the side wall of the locking member 3 along the insertion direction of the insertion member 22, and the guide slope 71 in the insertion slot 51 gradually moves away from the side wall of the locking member 25 along the insertion direction of the insertion member 25. When the insertion member 22 is inserted into the insertion slot 31 and the insertion member 25 is inserted into the insertion slot 51, the hook part 221 first contacts the guide slope 71. Then, as the insertion member 22 and the insertion member 25 are continued to be inserted, the hook part 221 will move along the guide slope 71 until the hook part 221 moves to hook onto the end face of the limiting protrusion 7 facing away from the blocking member 21. By providing a guide slope 71 on the limiting protrusion 7, the hook part 221 can be guided to hook onto the limiting protrusion 7. The guide slope 71 can provide a guiding function, which facilitates the insertion and installation of the first insert 22 and the second insert 25.
[0060] Optionally, two limiting plates are provided at one end of the stop plate 4 away from the locking member 3, and two limiting plates are provided at one end of the stop plate 6 away from the locking member 25. The limiting plates of the two stop plates 4 extend along the side closest to each other, and the limiting plates abut against the insert 22. The limiting plates of the two stop plates 6 extend along the side closest to each other, and the limiting plates abut against the insert 25. When the insert 22 is inserted into the insertion slot 31, the two limiting plates abut against the side wall of the insert 22, that is, press against the side wall of the insert 22, thereby preventing the insert 22 from detaching from the insertion slot 31. Similarly, the two limiting plates abut against the side wall of the insert 25, that is, press against the side wall of the insert 25, thereby preventing the insert 25 from detaching from the insertion slot 51, thus improving the connection stability between the shield 21 and the housing 1.
[0061] Optionally, such as Figure 3 and Figure 6 As shown, the heat dissipation structure also includes a support member 8. The support member 8 is disposed within the receiving cavity 11 and located at the through hole, and the support member 8 abuts against the shielding flange 23. By providing the support member 8, the shielding member 21 and the shielding flange 23 can be supported, and the shielding member 21 can be limited to prevent the shielding flange 23 from being embedded too much, which would cause the first heat dissipation channel 24 to be too large, and prevent a large amount of dust and moisture from entering the receiving cavity 11.
[0062] In this embodiment, two support members 8 are provided. In other embodiments, other numbers of support members 8 may be provided as needed, and this is not limited here.
[0063] Example 2
[0064] This embodiment provides a cleaning device 100, such as... Figure 1 and Figure 2 As shown, the heat dissipation structure includes that of Embodiment 1. By providing this heat dissipation structure, the cleaning device 100 can effectively prevent dust, moisture, and other impurities from entering its interior, thus avoiding damage to components and extending the service life of the cleaning device 100.
[0065] Example 3
[0066] In this embodiment, the mounting part 12 has a base plate, and at least one hollowed-out second heat dissipation channel is provided on the base plate. The second heat dissipation channel can be multiple heat dissipation holes, heat dissipation strips, or other feasible methods.
[0067] In this embodiment, the second heat dissipation channel and the first heat dissipation channel 24 are combined to form a heat dissipation connection channel.
[0068] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
