Description

Technical fields:

[0001] This utility model relates to the field of environmentally friendly vacuum cleaner technology, and specifically refers to a vacuum cleaner cover for an environmentally friendly vacuum cleaner. Background technology:

[0002] During the grinding process, a large amount of high-temperature dust is generated, and traditional single-layer dust collection devices have significant drawbacks. Their suction power is concentrated only at the air inlet, resulting in a low suction rate for larger particles, making it difficult to meet the requirements for efficient dust removal. Furthermore, the traditional flexible hose connection is located on the front of the dust hood; when high-temperature dust enters the dust hood from the front, it is easily damaged, shortening the equipment's lifespan. For example, Chinese utility model patent CN 208230489 U discloses an environmentally friendly dust collection hood, including a suction pipe with a suction pipe connector at its bottom. The inner bottom of the suction pipe connector is equipped with a dust collection hood. First fixing posts are installed on both sides of the suction pipe connector. A first connecting rod is installed inside a third connecting rod, and a second connecting rod is installed inside the first connecting rod. The second connecting rod passes through a first baffle and a first connecting post, and the fixing rod passes through the first connecting post. In this environmentally friendly dust collection hood, the suction hose is located on the front of the hood. When high-temperature dust enters the hood from the front, it can easily damage the telescopic hose and shorten the service life of the equipment.

[0003] In view of the above, the inventors propose the following technical solution. Utility Model Content:

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an environmentally friendly vacuum cleaner cover.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a dust cover for an environmentally friendly vacuum cleaner, comprising: a dust cover body, wherein a horn groove and a suction pipe interface are provided on the dust cover body, wherein the suction pipe interface is located on one side of the horn groove, and a sandwich structure communicating with the suction pipe interface is provided on one side of the inner wall of the horn groove, and an annular wall opening for communicating with the horn groove and the suction pipe interface is provided on the edge of the sandwich structure.

[0006] Furthermore, in the above technical solution, one side of the outer wall of the dust hood body is set as an outer arc surface, which extends to the other side, and the dust suction pipe interface is located on the side of the outer arc surface.

[0007] Furthermore, in the above technical solution, the inner wall of the dust collection hood body is provided with an inner arc surface that extends inward from the opening of the horn slot along the outer arc surface, and the bottom of the inner arc surface gradually extends away from the outer arc surface to the opening of the ring wall.

[0008] Furthermore, in the above technical solution, the sandwich structure includes an inner arc surface and a first inclined surface and a second inclined surface located at both ends of the inner arc surface, and one side of the first inclined surface and the second inclined surface extends to the opening of the horn groove, and the other side of the first inclined surface and the second inclined surface extends to the opening of the annular wall.

[0009] Furthermore, in the above technical solution, the middle of the first inclined surface and the second inclined surface are bent, and one end of the first inclined surface and the second inclined surface extends vertically into the interior of the horn groove.

[0010] Furthermore, in the above technical solution, the dust hood body includes an outer arc surface, a vertical plate, a left side plate, and a right side plate that surround each other to form a horn-shaped opening. One end of the outer arc surface extends to the end of the vertical plate, and the dust suction pipe interface is disposed on the left side plate or the right side plate.

[0011] Furthermore, in the above technical solution, a sandwich cavity is formed between the outer arc surface, the vertical plate, the left side plate and the inner arc surface, the first inclined surface and the second inclined surface, and the opening of the annular wall is located between the vertical plate and the sandwich cavity.

[0012] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: The present invention adopts a sandwich structure inside the horn groove to resist the impact of high temperature particles, thereby preventing high temperature particles from being directly sucked into the suction pipe. The suction pipe interface is set on the side of the horn groove, further reducing the risk of high temperature particles being sucked into the suction pipe. This effectively prevents high temperature particles generated during processing from impacting the suction pipe and causing damage, and greatly improves the service life of the suction pipe.

[0017] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0018] See Figures 1 to 4As shown, an environmentally friendly vacuum cleaner hood includes a hood body 1, a horn-shaped slot 2, and a suction pipe interface 3. The suction pipe interface 3 is located on one side of the horn-shaped slot 2. A sandwich structure 4 connecting the suction pipe interface 3 is provided on one side of the inner wall of the horn-shaped slot 2, and an annular opening 5 for connecting the horn-shaped slot 2 and the suction pipe interface 3 is provided on the edge of the sandwich structure 4. By setting the sandwich structure 4 inside the horn-shaped slot 2, the sandwich structure 4 resists the impact of high-temperature particles, preventing high-temperature particles from being directly sucked into the suction pipe. Furthermore, placing the suction pipe interface 3 on the side of the horn-shaped slot 2 further reduces the risk of high-temperature particles being sucked into the suction pipe, thereby effectively preventing damage to the suction pipe caused by high-temperature particles generated during processing, and significantly extending the service life of the suction pipe. Secondly, when the vacuum cleaner is working, a negative pressure is generated at the suction pipe interface 3, allowing dust falling around the annular opening 5 to be quickly sucked away.

[0019] One side of the outer wall of the dust hood body 1 is provided as an outer arc surface 11, which extends to the other side, and the dust suction pipe interface 3 is located on the side of the outer arc surface 11.

[0020] The inner wall of the dust collection hood body 1 is provided with an inner arc surface 41 extending inward from the opening of the horn slot 2 along the outer arc surface 11. The bottom of the inner arc surface 41 gradually extends away from the outer arc surface 11 to the opening of the ring wall 5.

[0021] The sandwich structure 4 includes an inner arc surface 41 and a first inclined surface 42 and a second inclined surface 43 located at both ends of the inner arc surface 41. One side of the first inclined surface 42 and the second inclined surface 43 extends to the opening of the horn groove 2, and the other side of the first inclined surface 42 and the second inclined surface 43 extends to the opening of the annular wall 5.

[0022] The first inclined surface 42 and the second inclined surface 43 are bent in the middle, and one end of the first inclined surface 42 and the second inclined surface 43 extends vertically into the interior of the horn groove 2.

[0023] The dust collection hood body 1 includes an outer arc surface 11, a vertical plate 12, a left side plate 13 and a right side plate 14 that surround each other to form a horn-shaped groove 2. One end of the outer arc surface 11 extends to the end of the vertical plate 12, and the dust collection pipe interface 3 is provided on the left side plate 13 or the right side plate 14.

[0024] An interlayer cavity 40 is formed between the outer arc surface 11, the vertical plate 12, the left side plate 13 and the inner arc surface 41, the first inclined surface 42, and the second inclined surface 43, and the annular wall opening 5 is located between the vertical plate 12 and the interlayer cavity 40.

[0025] In summary, in this utility model, the outer shape of the vacuum cleaner body 1 is set as a horn-shaped groove 2, and the inner and outer parts are set as a sandwich structure 4. There is a sandwich cavity 40 between the sandwich structure 4 and the inner wall of the horn-shaped groove 2. An annular wall opening 5 is set at the bottom of the inner layer. The vacuum cleaner's suction pipe is a telescopic flexible hose. The suction pipe interface 3 is located on the side of the vacuum cleaner body 1, and the suction pipe interface 3 is connected to the sandwich cavity 40.

[0026] When the vacuum cleaner generates suction, a negative pressure is generated in the internal cavity of the vacuum cleaner body 1. Dust and debris are drawn into the interlayer cavity 40 of the vacuum cleaner hood's horn slot 2 through the ring wall opening 5 at the bottom of the inner layer of the vacuum cleaner body 1. Then, the dust and debris are drawn into the vacuum cleaner through the vacuum tube interface 3.

[0027] In the above solution, the suction pipe interface 3 is located on the side of the dust hood body 1. When high-temperature dust enters the horn-shaped groove 2 of the dust hood body 1, the high-temperature particles will repeatedly impact the sandwich structure 4 of the dust hood, achieving a certain cooling effect. The cooled dust will enter the sandwich cavity 40 from the bottom annular wall opening 5 of the sandwich structure 4 inside the dust hood, and then enter the suction pipe interface 3. This avoids high-temperature dust directly hitting the telescopic hose during grinding and causing damage to it. Secondly, placing the suction pipe interface 3 on the side of the dust hood body 1 also saves installation space for the dust hood body 1.

[0028] Of course, the above description is only a specific embodiment of the present utility model and is not intended to limit the scope of the present utility model. All equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model should be included in the scope of the claims of the present utility model.
