Description

Technical Field

[0001] This application relates to the technical field of cooling fans, and particularly to a cooling fan and an electronic product. Background Art

[0002] The fans in the prior art do not have a dust removal structure. Dust accumulates on the blades, affecting the use effect. For fans with a dust removal structure, such as the dust removal structure described in the patent with the title "A Fixed Base for a Computer Fan with Dust and Noise Prevention" and application number CN201820433799.7, the dust removal work is achieved by "placing a water-mixed activated carbon cotton layer inside the dust suction inlay card slot 6". It has the following disadvantages: The dust inlet of the card slot is parallel to the wind direction during the operation of the fan. After the water on the activated carbon cotton layer evaporates, the dust absorption effect decreases, and the dust cannot enter the card slot well, resulting in a poor dust removal effect. Summary of the Utility Model

[0003] The purpose of this application is to provide a cooling fan and an electronic product to collect and store the dust during the operation of the cooling fan inside the through holes of the dust removal structure, thereby achieving the dust removal work.

[0026] Next, the technical solutions in the embodiments of the present disclosure / application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The description of at least one exemplary embodiment below is actually only illustrative and in no way limits the present application and its application or use. Embodiment

[0027] As Figures 1-5 shown, this embodiment provides a cooling fan, including a fan reserved cavity and a fan arranged in the fan reserved cavity. The fan reserved cavity includes a fan base and a side plate located on the side of the fan base. The fan is installed on the fan base.

[0028] A dust removal structure 201 is provided on the side plate 2. The dust removal structure 201 includes a through hole 203 opened on the side plate 2 and a flap 202 corresponding to the through hole 203.

[0029] One end of the flap 202 is a connection end fixed at the edge of the through hole 203, and the other end is a free end. The free end extends obliquely into the fan reserved cavity, and at least one tip 204 is provided at the free end. The tip 204 is used to collect strip-shaped flocs in the wind.

[0030] A plurality of through holes 203 are provided on the side plate 2, and adjacent through holes 203 are staggeredly distributed on the side plate 2 to collect dust in the wind more comprehensively.

[0031] The free end of the flap 202 and the through hole 203 form a dust removal inlet, and the dust removal inlet is arranged towards the windward surface of the fan. When the fan is working, the wind enters the through hole 203 from the dust removal inlet, and the dust carried in the wind is blocked by the flap 202 and remains inside the through hole 203.

[0032] The side plate 2 and the fan base 1 are of an integral structure. The side plate 2 is fixed in the groove 301 of the side wall structure 3 on the side wall of the fan base 1. A collection cavity is formed between the side plate 2 and the side wall structure 3 for storing dust. The side wall structure 3 is detachably fixed on the fan base 1, and the side wall structure 3 can be disassembled to clean the stored dust. The collection cavity is very small, and the resistance generated can be ignored.

[0033] The baffle 202 is in an arc shape that is concave towards the interior of the fan reserved cavity. The lowest point of the concavity on the baffle 202 is parallel to the surface of the side wall structure 3, which will not interfere with the normal operation of the fan. Embodiment

[0034] As Figure 6 shown, this embodiment provides a technical solution based on Embodiment 1. The difference from Embodiment 1 is that the through hole 203 and the baffle 202 are semi-elliptical structures. The connecting end and both sides of the baffle 202 are fixed at the edge of the through hole 203, which can better collect dust into the collection cavity and prevent it from flowing out from both sides of the baffle. The free end is provided with a tip 204 for collecting strip-shaped flocs in the wind.

[0035] During use, the wind passes through the dust removal inlet formed by the free end of the baffle 202 and the through hole, and then enters the collection cavity formed by the baffle 202 and the side wall structure. The dust is blocked by the fixed end of the baffle and stored in the collection cavity, completing the dust removal during the use of the fan. Embodiment

[0036] As Figures 7-8 shown, this embodiment provides a technical solution based on Embodiment 1. The difference from Embodiment 1 is that the through hole 203 and the baffle 202 are rectangular structures. The connecting end of the baffle 202 is fixed at the edge of the through hole 203, and the free end is provided with a plurality of tips 204, which can better collect strip-shaped flocs in the wind.

[0037] During use, the wind passes through the dust removal inlet formed by the free end of the baffle 202 and the through hole, and then enters the collection cavity formed by the baffle 202 and the side wall structure. The dust is blocked by the fixed end of the baffle and stored in the collection cavity, completing the dust removal during the use of the fan. Embodiment

[0038] This embodiment provides an electronic product, including the heat dissipation fan provided in Embodiment 1 or Embodiment 2 or Embodiment 3. It can better collect and store the dust inhaled during the operation of the fan, avoiding a large amount of dust adhering to the fan blades and affecting its working efficiency.

[0039] The above are only the preferred embodiments of the present application. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present application, several improvements and deformations can be made, and these improvements and deformations should also be regarded as the protection scope of the present application.
