Description

Technical Field

[0001] The utility model relates to the technical field of computers, in particular to an easy-to-clean host dust-proof filter. Background Art

[0002] When the computer host is running, there must be heat dissipation holes on the host case to reduce the heat dissipation of electrical components such as the motherboard and CPU. However, this makes it easy for dust to enter and contaminate the internal circuits of the computer, affecting the service life and performance of the host.

[0003] In order to prevent a lot of dust from entering the main chassis during the heat dissipation process of the computer, most of them will be equipped with dust filters at the heat dissipation holes of the main chassis. In order to ensure the stability after installation, traditional dust filters are mostly fixed on the main chassis by multiple sets of bolts. With the long-term use of people, a lot of dust will be collected on the dust filter. At this time, people need to remove the multiple sets of bolts before they can remove the dust filter for cleaning. The whole cleaning process is too cumbersome and cannot meet people's usage needs.

[0011] As a further solution of the utility model: the top of the first dust filter is located at the same horizontal plane as the top of the casing, so as to avoid a lot of dust being hidden inside the installation groove.

[0012] As a further solution of the utility model: a second adhesive layer is provided on the outer wall of the first dust filter screen close to the magnetic strip, and a connecting belt is bonded to the second adhesive layer, so that people can pull the connecting belt to lift the first dust filter screen.

[0013] As a further solution of the utility model: the number of connecting belts is two groups, the cross-section of the first dustproof filter is rectangular, and the two groups of connecting belts are arranged at the two long sides of the first dustproof filter.

[0014] As a further solution of the utility model: one end of the connecting belt away from the second adhesive layer is fixedly connected to a cylindrical portion, and one end of the cylindrical portion is fixedly connected to a spherical portion.

[0015] As a further solution of the utility model: the bottom of the casing is provided with heat dissipation holes distributed at equal distances, the bottom of the casing is fixedly connected with a first baffle and a second baffle, the cross-sections of the first baffle and the second baffle are both L-shaped, the number of the first baffle and the second baffle are both four groups, the first baffle and the second baffle are distributed vertically in pairs, and a second dust filter is provided at the bottom of the casing, and the four sides of the second dust filter are all in contact with the inner wall of one side of the first baffle and the second baffle.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example 1

[0027] See also Figure 1 to Figure 4 In an embodiment of the utility model, an easy-to-clean host dust filter includes a casing 1, the bottom of the casing 1 is fixedly connected with support legs 11, the number of the support legs 11 is four groups, and the four groups of support legs 11 are distributed at the four corners of the bottom of the casing 1; a mounting groove 3 is opened on the top of the casing 1, and an air hole is opened at the bottom of the mounting groove 3. A first dust filter 2 is arranged inside the mounting groove 3, and the first dust filter 2 covers the top of the air hole.

[0028] By covering the top of the air hole with the first dustproof filter 2, dust and the like can be effectively prevented from entering the interior of the housing 1 through the air hole.

[0029] A first adhesive layer 7 is provided at the bottom of the first dust filter 2, and the first dust filter 2 is fixedly connected to a magnetic strip 6 through the first adhesive layer 7. The bottom inner wall of the mounting groove 3 is made of metal material, and the magnetic strip 6 is adsorbed to the bottom inner wall of the mounting groove 3. The first dust filter 2 is fixed to the inside of the mounting groove 3 through the magnetic strip 6. The number of the magnetic strips 6 is four groups, and the four groups of magnetic strips 6 are distributed in the area near the side wall of the bottom of the first dust filter 2. The top of the first dust filter 2 is located on the same horizontal plane as the top of the casing 1.

[0030] Since the first dust filter 2 is adsorbed on the bottom of the installation groove 3 by the magnetic strip 6, not only the stability of the first dust filter 2 can be ensured after installation, but also when there is a lot of dust on the surface of the first dust filter 2, it can be easily removed from the inside of the installation groove 3, which is convenient for people to clean the first dust filter later. It is more convenient for people to clean it than the traditional bolt fixing. The top of the first dust filter 2 is on the same horizontal plane as the top of the casing 1, which can effectively prevent a lot of dust from being hidden inside the installation groove 3.

[0031] A second adhesive layer 8 is provided on the outer wall of the first dust filter 2 on one side close to the magnetic strip 6, and the second adhesive layer 8 is bonded with connecting belts 4. There are two groups of connecting belts 4. The cross-section of the first dust filter 2 is rectangular. The two groups of connecting belts 4 are provided at the two long sides of the first dust filter 2. One end of the connecting belt 4 away from the second adhesive layer 8 is fixedly connected to a cylindrical part, and one end of the cylindrical part is fixedly connected to a spherical part 5.

[0032] When people need to disassemble the first dust filter 2, they can pull the spherical part 5 to drive the connecting belt 4 to rise, so that the first dust filter 2 can be quickly removed from the inside of the installation groove 3, avoiding the situation that the first dust filter 2 is too strongly adsorbed to the installation groove 3 and there is no fulcrum on its surface, making it difficult to disassemble.

[0033] Example 2

[0034] See also Figure 5 Compared with Example 1, this embodiment also includes that the bottom of the casing 1 is provided with heat dissipation holes 10 distributed at equal distances, the bottom of the casing 1 is fixedly connected with a first baffle 12 and a second baffle 13, the cross-sections of the first baffle 12 and the second baffle 13 are both L-shaped, the number of the first baffle 12 and the second baffle 13 are both four groups, the first baffle 12 and the second baffle 13 are distributed vertically in pairs, and a second dust filter 9 is arranged at the bottom of the casing 1, and the four sides of the second dust filter 9 are all in contact with the inner wall of one side of the first baffle 12 and the second baffle 13.

[0035] The second dust filter 9 is fixedly installed by having four sides abutting against the inner wall of one side of the first baffle 12 and the second baffle 13. Therefore, the second dust filter 9 does not need to be fixed by multiple sets of bolts, which facilitates people's subsequent quick disassembly and cleaning.

[0036] Working principle: In the utility model, since the first dust filter 2 is adsorbed on the bottom of the installation groove 3 by the magnetic strip 6, it can not only ensure the stability of the first dust filter 2 after installation, but also can be easily removed from the inside of the installation groove 3 when there is a lot of dust on the surface of the first dust filter 2, which is convenient for people to clean the first dust filter 2 later. At the same time, when people need to disassemble the first dust filter 2, they can pull the spherical part 5 to drive the connecting belt 4 to rise, so that the first dust filter 2 can be quickly removed from the inside of the installation groove 3, avoiding the situation that the first dust filter 2 is too adsorbed to the installation groove 3 and there is no fulcrum on its surface, which makes disassembly difficult.

[0037] It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
