[0002] The filter is an electrical device that effectively filters out a specific frequency point in the power line or frequencies other than the specific frequency point.

[0025] Example 1

[0026] Since the filter housing is usually a detachable housing, and a heat dissipation mesh plate 41 is usually provided on the filter housing, so that heat is dissipated through the heat dissipation mesh plate 41. When the filter is placed for a long time, a lot of dust is easily accumulated on the heat dissipation mesh plate 41. At this time, if the heat dissipation mesh plate 41 is not processed, dust will enter the filter, affecting the heat dissipation efficiency; and if the heat dissipation mesh plate 41 is removed by disassembly for cleaning, during the disassembly process, due to the movement of the heat dissipation mesh plate 41, a lot of dust is also easy to fall and enter the filter, affecting the heat dissipation efficiency.

[0027] Therefore, the utility model provides a filter that is easy to disassemble and install. A fixing part 2 is symmetrically arranged on the filter housing. The heat dissipation mesh plate 41 can slide in the fixing part 2, which is convenient for the staff to disassemble and install the heat dissipation mesh plate 41. In addition, a dust shielding mechanism is arranged under the heat dissipation mesh plate 41 to prevent the dust on the heat dissipation mesh plate 41 from falling into the filter during the process of the staff disassembling the heat dissipation mesh plate 41, thereby preventing the heat dissipation efficiency from being affected.

[0028] Specifically, Figure 1 , Figure 2 , Figure 3 As shown, a filter that is easy to disassemble and install includes a filter housing, the filter housing includes a shell body 1, a shell cover 4 located above the shell body 1, fixing parts 2 are symmetrically arranged on the top of the side wall of the shell body 1, two fixing parts 2 are provided with grooves 3 in corresponding directions, and the grooves 3 extend from the front to the back of the shell body 1 in the horizontal direction, the two sides of the shell cover 4 are embedded in the corresponding grooves 3, and a heat dissipation mesh plate 41 is provided at the center of the shell cover 4, a dust shielding mechanism is symmetrically arranged below the heat dissipation mesh plate 41, and through holes located below the grooves 3 are symmetrically opened on the side wall of the shell body 1, and the dust shielding mechanism moves toward the shell body 1 through the corresponding through holes.

[0029] Preferably, the dust blocking mechanism includes a dust removal plate 5, and the dust removal plate 5 is connected to another dust removal plate 5 through a through hole, and the height of the top end of the dust removal plate 5 toward the other dust removal plate 5 is greater than the height of the top end of the dust removal plate 5 away from the other dust removal plate 5, so that the top end surface of the dust removal plate 5 is inclined.

[0030] Preferably, a push rod 6 is provided on the side of the dust removal plate 5 away from the other dust removal plate 5, and the push rod 6 is horizontally arranged. A support plate 7 is symmetrically arranged on the outer wall of the shell body 1, and the push rod 6 is connected to the support plate 7 through a tightening bolt 8.

[0031] Preferably, the cross-sectional shape of the dust removal plate 5 along the vertical direction is a right triangle, and the hypotenuse of the right triangle faces the heat dissipation mesh plate 41 .

[0032] Preferably, the top end surface of the dust removal plate 5 is an inwardly recessed concave surface, and the concave surface is used to collect dust.

[0033] Preferably, a plurality of guide grooves are provided on the top surface of the dust removal plate 5, and the guide grooves extend from the dust removal plate 5 toward the top of another dust removal plate 5 and away from the top of another dust removal plate 5, for collecting and guiding out dust. The purpose is to collect dust falling from the heat dissipation mesh plate 41, so as to facilitate the subsequent cleaning of the heat dissipation mesh plate 41.

[0034] Preferably, the height of the through hole is equal to or greater than the height of the top of the dust removal plate 5 facing the other dust removal plate 5. The purpose is to ensure that the dust removal plate 5 can move in the through hole.

[0035] Preferably, the limiting parts 42 are symmetrically arranged on both sides of the heat dissipation mesh plate 41 , and the limiting parts 42 are embedded in the corresponding grooves 3 , and the inner surface of the grooves 3 is a smooth surface, so that the limiting parts 42 slide along the extension direction of the grooves 3 .

[0036] Preferably, one end of the groove 3 is connected to the outer wall of the shell body 1, and the other end of the groove 3 is connected to the inner wall of the shell body 1, and one end of the groove 3 is provided with a buckle, and the other end of the groove 3 is provided with a protective layer 31. The purpose is to prevent the limiting part 42 from colliding with the deep part of the groove 3 when sliding along the groove 3, thereby causing damage to the limiting part 42.

[0037] Based on the above principle, in this embodiment, the specific working process of the filter that is easy to disassemble and install is as follows:

[0038] When the staff needs to use the filter, the filter is installed, that is, the limiting part 42 of the shell cover 4 is slid into the groove 3, so that the shell cover 4 is located directly above the shell body 1, and a protective layer 31 is provided deep in the groove 3, and the protective layer 31 can protect the limiting part 42 from colliding with the groove 3 to prevent the limiting part 42 from being damaged. When the groove 3 is in contact with the protective layer 31, the limiting part 42 is fixed in the groove 3 by a snap buckle. The operation is simple and convenient for the staff to install. At the same time, the staff manipulates the push rod 6 and pulls the push rod 6 outward so that the dust removal plate 5 is not located between the filter and the heat dissipation mesh plate 41, that is, the dust removal plate 5 is not located below the heat dissipation mesh plate 41, so that the heat generated by the filter can be dissipated outward through the heat dissipation mesh plate 41.

[0039] When the staff needs to disassemble the shell cover 4, first, it is necessary to operate the push rod 6, push the push rod 6 through the through hole and push it inward so that the dust removal plates 5 on both sides are connected in abutment with each other, and then fix the push rod 6 on the support plate 7 by tightening the bolts 8 to prevent the dust removal plates 5 from moving and ensure the stability of the dust removal plates 5, and then, unlock the buckle of the limit part 42, and slide the heat dissipation mesh plate 41 outward through the groove 3. At this time, if the dust on the heat dissipation mesh plate 41 falls off, the dust will fall onto the dust removal plate 5, and through the inclined setting of the dust removal plate 5, the dust can be slid to both sides for collection. After waiting for the heat dissipation mesh plate 41 to be removed, the push rod 6 can be operated to be pulled outward to sweep the dust on the dust removal plate 5 to prevent the dust from falling into the shell body 1, which is inconvenient for the staff to clean, thereby affecting the subsequent heat dissipation efficiency.

[0040] It is understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the present invention, but the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
