Description

Technical Field

[0001] The utility model relates to the technical field of dust filter bags, in particular to a convenient and clean dust filter bag. Background Art

[0002] Dust refers to solid particles suspended in the air. Dust is usually called by many names, such as dust, dust, smoke, mineral dust, sand dust, powder, etc., and there is no clear boundary between these terms. The International Organization for Standardization stipulates that solid suspended matter with a particle size of less than 75μm is defined as dust.

[0003] In the existing air purification equipment, most of the built-in filter elements use dust filter bags to isolate and filter the dust from the outside. However, most of the dust filter bags of the air purification equipment on the market adopt an angled inner and outer angle structure design, as shown in the attached manual. Figure 3 As shown, in practice, the filter bag with this structural design is prone to hiding dust in the deep angle, which is inconvenient to clean. After long-term use, it is easy to cause a large amount of dust accumulation, affecting the actual filtering effect and service life of the filter element. For this reason, the utility model proposes a clean dust filter bag with a circular arc surface. Utility Model Content

[0004] The purpose of the utility model is to provide a convenient and clean dust filter bag to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a convenient and clean dust filter bag, comprising a filter bag body, the filter bag body adopts a cylindrical structure design, the outside of the filter bag body is folded with a plurality of annularly distributed grooves, the outer corners of the filter bag are arranged deep outside the grooves of the filter bag body, the inner corners of the filter bag are arranged inside the top of the grooves of the filter bag body, and the outer corners and the inner corners of the filter bag are both arranged with arc surface structures.

[0006] Preferably, the arc surface of the outer corner of the filter bag is larger than the arc surface of the inner corner of the filter bag.

[0007] Compared with the prior art, the beneficial effects of the utility model are:

[0008] The outer surface of the filter bag body of the utility model is folded with a plurality of annularly distributed grooves. The structural design of the grooves can effectively improve the contact and filtration effect with dust. Compared with the cylindrical filter bag with a smooth surface, the utility model can block and isolate the dust entering the inner part of the grooves through the uneven groove design, so as to prevent the dust attached to the filter bag body from floating left and right, which can effectively increase the contact area with dust, effectively improve the filtration quality, and have a better dust contact and filtration effect;

[0009] At the same time, the outer corners and inner corners of the filter bag are both arranged with an arc surface structure, and the arc surface has a certain expansion area. Therefore, when the filter bag is actually used, the arc surface of the outer corners and the inner corners of the filter bag will be directly exposed to the environment, with a large contact area and no cleaning dead corners. Compared with the angled filter bags in the prior art, the arc surface filter bags of the utility model are more convenient for regular cleaning and maintenance, and can effectively clean the dust deep in the gullies. The larger arc surface contact area can effectively avoid the problem of being unable to clean deep in the angle, thereby effectively avoiding the accumulation of dust caused by long-term inadequate cleaning, and effectively increasing the overall purification effect, quality and service life of the filter element.

[0018] The outer part of the filter bag body 1 is folded with a plurality of annularly distributed grooves 101. The structural design of the grooves 101 can effectively improve the contact and filtration effect with dust. Compared with the cylindrical filter bag with a smooth surface, the utility model can block and isolate the dust entering the grooves through the uneven groove design, so as to prevent the dust attached to the filter bag body 1 from floating left and right, and can effectively increase the contact area with dust, effectively improve the filtration quality, and have a better dust contact and filtration effect;

[0019] In addition, a filter bag outer corner 102 is arranged deep outside the groove 101, and a filter bag inner corner 103 is arranged inside the top of the groove 101 of the filter bag body 1. The filter bag outer corner 102 and the filter bag inner corner 103 are both arranged with arc surface structures. For details of this structural design, please refer to the attached manual. Figure 2 As shown, when the filter bag outer corner 102 and the filter bag inner corner 103 are actually used, their arc surfaces will be directly exposed to the environment, with a large contact area and no cleaning dead corners. Compared with the angled filter bag in the prior art, the arc surface filter bag of the utility model is more convenient to clean and maintain, and can effectively clean the dust deep in the gully, thereby effectively avoiding the accumulation of dust caused by long-term inadequate cleaning, and effectively increasing the overall purification effect and service life of the filter element;

[0020] For further details, please refer to the attached manual. Figure 2 As shown, the arc surface of the outer corner 102 of the filter bag is larger than the arc surface of the inner corner 103 of the filter bag. With this structural design, when the filter bag is actually in use, external dust enters the outer surface of the outer corner 102 of the filter bag through the groove 101. Therefore, making the arc surface of the outer corner 102 of the filter bag larger can effectively increase the contact area with the dust, improve the filtering effect, and avoid structural dead angles, thereby improving the cleaning quality.

[0021] Working principle: When the utility model is in use, the filter bag of the utility model can be installed on the filter element adapted to the utility model, so as to ensure the normal use of the utility model;

[0022] The filter bag body 1 of the utility model is folded with a plurality of annularly distributed grooves 101 on the outside. The structural design of the grooves 101 can effectively improve the contact and filtration effect with dust. Compared with the cylindrical filter bag with a smooth surface, the utility model can block and isolate the dust entering the inside of the grooves through the uneven groove design, so as to prevent the dust attached to the filter bag body 1 from floating left and right, and can effectively increase the contact area with dust, effectively improve the filtration quality, and have a better dust contact and filtration effect;

[0023] At the same time, the outer corner 102 of the filter bag and the inner corner 103 of the filter bag are both arranged with an arc surface structure, and the arc surface has a certain expansion area. Therefore, when the outer corner 102 of the filter bag and the inner corner 103 of the filter bag are actually used, the arc surface will be directly exposed to the environment, with a large contact area and no cleaning dead corners. Compared with the angled filter bags in the prior art, the arc surface filter bags of the utility model are more convenient for regular cleaning and maintenance, and can effectively clean the dust deep in the gullies. The larger arc surface contact area can effectively avoid the problem of being unable to clean deep in the angle, thereby effectively avoiding the accumulation of dust caused by long-term inadequate cleaning, and effectively increasing the overall purification effect, quality and service life of the filter element.

[0024] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
