Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of radiating fan, and specifically relates to a dustproof fan. BACKGROUND

[0002] In the existing dustproof technology of radiating fan, a simple dust screen is mainly added to the fan shell, or a dust baffle is arranged at the fan exhaust position, so as to basically prevent dust. Although these methods can reduce the pollution of dust to the radiating equipment to a certain extent, the dustproof effect is limited, and as the use time of the fan increases, the dust accumulation on the dust screen or baffle increases more and more, which not only seriously affects the ventilation and heat dissipation effect, but also increases the failure rate of internal components caused by long-term dust accumulation.

[0003] In order to improve this situation, some advanced radiating fans are designed with front filter screen with long-acting filter material, and fast disassembly design is adopted to facilitate users to clean regularly. At the same time, some high-end products also combine dustproof design with intelligent monitoring, detect the internal dust concentration through sensors, and once the preset threshold is reached, the system will automatically start the self-cleaning mode. However, these improvements, although improving the dustproof effect to a certain extent, still have complex maintenance operation and high cost problems in actual application.

[0029] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0030] like Figures 1-2 As shown, a dustproof fan in one embodiment of the present invention includes a fan body 1. Mounting holes 101 are provided at the four corners of the fan body 1. Bolts are inserted into the mounting holes 101 and connected to the device through the bolts to fix the fan body 1.

[0031] like Figures 1-2 As shown, a filter assembly 4 is installed at the air inlet end of the fan body 1. The filter assembly 4 can filter impurities to reduce the amount of impurities in the air entering the fan body 1. A connecting ring 2 that matches the filter assembly 4 is fixedly connected to the fan body 1. The outer wall of the connecting ring 2 has an external thread 201, and a pressure ring 3 is installed on the connecting ring 2. The inner wall of the pressure ring 3 has an internal thread 301 that matches the external thread 201. The external thread 201 and the internal thread 301 enable a threaded connection between the connecting ring 2 and the pressure ring 3. The filter assembly 4 is located between the connecting ring 2 and the pressure ring 3, i.e., the filter assembly 4 is snapped and fixed to the connecting ring 2 and the pressure ring 3.

[0032] like Figures 1-7 As shown, the filter assembly 4 includes a first filter plate 5 and a second filter plate 6. Both the first filter plate 5 and the second filter plate 6 have filter holes 9. Multiple elastic wires 7, matching the filter holes 9, are fixedly connected to the opposite surfaces of the first filter plate 5 and the second filter plate 6. The elastic wires 7 on the first filter plate 5 and the second filter plate 6 are staggered. When the first filter plate 5 and the second filter plate 6 are in contact, the elastic wires 7 on the first filter plate 5 and the second filter plate 6 form a staggered secondary filtration structure. The pore size of the secondary filtration structure is smaller than that of the filter holes 9, and it can divide the filter holes 9, performing secondary filtration on the air entering through the filter holes 9, making the air entering the equipment cleaner. Furthermore, the secondary filtration structure is composed of multiple elastic wires 7, which does not easily affect the airflow efficiency.

[0033] like Figures 5-7As shown, a connecting cylinder 501 is fixedly connected to the first filter plate 5, and a connecting post 601 matching the connecting cylinder 501 is fixedly connected to the second filter plate 6. The connecting post 601 can be inserted into the connecting cylinder 501 to achieve the splicing of the first filter plate 5 and the second filter plate 6. The connecting cylinder 501 and the connecting post 601 also ensure that the elastic wires 7 on the second filter plate 6 and the elastic wires 7 on the first filter plate 5 can cross, which is beneficial to the formation of the secondary filtration structure.

[0034] like Figure 7 As shown, multiple barbs 8 are fixedly connected to the elastic wire 7. The barbs 8 face the air inlet direction. When air enters, the barbs 8 can adsorb some impurities. The barbs 8 have sharp edges and rough surfaces, which increases the surface area of ​​the elastic wire 7, making it easier to adsorb surrounding impurities. The barbs 8 further enhance the filtration effect of the secondary filtration structure.

[0035] Because the secondary filtration structure has a better filtration effect than a regular filter, it is more prone to the accumulation of impurities, thus affecting the air intake effect of the fan body 1. To facilitate cleaning of the filter assembly 4, such as... Figures 1-4 As shown, the fan body 1 has grooves, and one or more grooves are fixedly connected to a placement slot 10. The placement slot 10 can be fixed by means of snap-fit, threaded connection, etc. The placement slot 10 can be installed in a suitable position in a detachable manner, and the installation position of the placement slot 10 is selected according to the actual situation.

[0036] like Figures 1-4 As shown, a cleaning brush 11 is installed on the placement slot 10. A second magnetic plate is fixedly connected to the cleaning brush 11, and a first magnetic plate 1001 matching the second magnetic plate is fixedly connected to the placement slot 10. The cleaning brush 11 is fixedly secured by the cooperation of the second magnetic plate and the first magnetic plate 1001. A rubber pad 12 matching the handle of the cleaning brush 11 is also fixedly connected to the placement slot 10, which strengthens the fixation of the cleaning brush 11.

[0037] When using the dustproof fan, the first filter plate 5 and the second filter plate 6 need to be combined, ensuring that the connecting post 601 can be inserted into the connecting cylinder 501. After the connecting post 601 is inserted into the connecting cylinder 501, the elastic wires 7 on the first filter plate 5 and the elastic wires 7 on the second filter plate 6 interweave, forming a secondary filtration structure. Then, the combined first filter plate 5 and second filter plate 6 are placed into the connecting ring 2, and the pressure ring 3 is threaded onto the connecting ring 2 to fix the first filter plate 5 and the elastic wires 7.

[0038] When the first filter plate 5 and the second filter plate 6 need to be dusted, the pressure ring 3 needs to be unscrewed, and then the first filter plate 5 and the second filter plate 6 need to be separated. The cleaning brush 11 on the placement slot 10 is removed and the first filter plate 5 and the second filter plate 6 are brushed with the cleaning brush 11 to remove the dust on the first filter plate 5 and the second filter plate 6. After the dust removal is completed, the first filter plate 5 and the second filter plate 6 can be installed on the fan body 1.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
