Abstract
Description
Technical Field
[0001] This utility model relates to the field of dustproof net technology, specifically a dustproof net structure that is easy to remove dirt from. Background Technology
[0002] In many fields, such as electronic equipment heat dissipation, air purification, and building ventilation, dust filters are key components that prevent dust and dirt from entering the system, and their performance directly affects the operating efficiency and service life of the equipment. However, traditional dust filter structures have many shortcomings in practical applications, such as the difficulty in removing dust and dirt.
[0003] Therefore, developing a dustproof net structure that is easy to remove dirt from in order to improve the ease of maintenance, extend the service life and reduce the maintenance cost of the dustproof net has become an urgent problem to be solved. Summary of the Invention
[0004] In order to overcome the shortcomings of existing technical solutions, this utility model provides a dustproof mesh structure that is easy to remove dirt, which can effectively solve the problem of dirt adhesion and difficulty in removal mentioned in the background technology.
[0005] The technical solution adopted by this utility model to solve its technical problem is: a dustproof mesh structure that is easy to remove dirt, including a mesh body and an array of concave holes distributed on the surface of the mesh body. A temperature-sensitive expansion metal part is embedded in the concave hole. When the temperature reaches a threshold, the metal part expands in volume and protrudes out of the opening plane of the concave hole.
[0006] Furthermore, the surface of the mesh is provided with an AF anti-fingerprint coating.
[0007] Furthermore, the thermochromic expanding metal part is a columnar body made of shape memory alloy with a phase transition temperature of 40-80℃.
[0008] Furthermore, the depth of the recess is 0.5-3mm, the diameter is 0.3-2mm, and the center distance between adjacent recesses is 1.5-3 times the diameter.
[0009] Furthermore, the thickness of the mesh is 0.8-5mm.
[0010] Furthermore, the back of the mesh body is provided with a thermally conductive channel communicating with the recessed holes, and the channel is filled with thermally conductive silicone grease.
[0011] Furthermore, the temperature-conducting channels are radially distributed.
[0012] Compared with existing technologies, the beneficial effects of this invention are as follows: When the ambient temperature or the heat generated by the equipment operation reaches the expansion threshold of the metal parts, the metal parts expand in volume and bulge out of the concave hole plane, directly squeezing and destroying the dust layer attached to the mesh surface. After the temperature decreases, the metal parts contract. This expansion-contraction process forms a periodic motion, which greatly weakens the adhesion between the dust and the mesh, and may even cause it to fall off directly. Compared with traditional passive dust screens, this structure achieves active cleaning through heat energy, significantly reducing the frequency of manual maintenance. Attached Figure Description

[0015] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.
[0016] The following specific examples illustrate the implementation of this disclosure. Those skilled in the art can easily understand other advantages and effects of this disclosure from the content disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. This disclosure can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this disclosure. It should be noted that, in the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure. Example
[0017] like Figure 1-3 As shown, this utility model provides the following: Figure 1-3 As shown, this utility model provides a dustproof mesh structure that is easy to remove dirt, including a mesh body 1 and recesses 2 arranged in an array on the surface of the mesh body 1. A temperature-sensitive expansion metal part 3 is embedded in the recesses 2. When the temperature reaches a threshold, the metal part expands in volume and protrudes out of the opening plane of the recesses 2.
[0018] When the ambient temperature or the heat generated by the equipment reaches the expansion threshold of the metal parts, the metal parts expand in volume and bulge out of the concave hole 2, directly squeezing and destroying the dirt layer attached to the surface of the mesh 1. After the temperature drops, the metal parts contract. This expansion-contraction process forms a periodic motion, which greatly weakens the adhesion between the dirt and the mesh 1, and may even cause it to fall off directly. Compared with traditional passive dust screens, this structure achieves active cleaning through heat energy, significantly reducing the frequency of manual maintenance.
[0019] See Figure 3 The surface of the mesh body 1 and the upper surface of the temperature-induced expansion metal part 3 are provided with an AF anti-fingerprint coating 4.
[0020] The AF anti-fingerprint coating 4 uses nano-chemical materials to reduce the surface energy of the material, thereby reducing the contact area between dust and the object's surface. This low surface energy characteristic significantly reduces the adhesion between dirt and the object's surface, making it difficult for dirt to adhere. After the mesh body 1 and metal parts are coated with the AF anti-fingerprint coating 4, they can effectively reduce the adhesion of fingerprints, oil, dust and other stains, keeping the surface clean.
[0021] Among them, the thermo-expanding metal part 3 is a columnar body made of shape memory alloy, and its phase transformation temperature is 40-80℃.
[0022] The depth of the concave hole 2 is 0.5-3mm, the diameter is 0.3-2mm, and the center distance between adjacent concave holes 2 is 1.5-3 times the diameter.
[0023] The thickness of mesh 1 is 0.8-5mm.
[0024] See Figure 3 The back of the mesh body 1 is provided with a heat conduction channel 5 that communicates with the recessed hole 2. The channel is filled with thermally conductive silicone grease 6, so that the temperature-expanding metal part 3 in the recessed hole 2 of the mesh body 1 directly contacts the bottom of the heat conduction channel 5, thereby shortening the temperature conduction time.
[0025] Among them, the heat conduction channels 5 are distributed radially, making the distribution of heat conduction channels 5 more extensive and the heat conduction more rapid.
