Detailed Implementation
[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0028] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0029] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0030] In the description of this utility model, unless otherwise specified and limited, it should be noted that the terms "installation", "connection" and "linking" should be interpreted broadly. For example, they can refer to mechanical or electrical connections, or internal connections between two components. They can be direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.
[0031] like Figures 1 to 7 As shown, the cleaning device provided by this utility model includes a plate 100, a collection component 200, and a cleaning component 300. The plate 100 is used to install the collection component 200 and the cleaning component 300. The cleaning component 300 is used to clean the fixture to be cleaned, and the collection component 200 is used to collect the dust generated by the cleaning component 300 during the cleaning process.
[0032] The collection assembly 200 includes a collection cavity 201 located within the plate 100, a through hole 202 disposed in the middle of the plate 100 and communicating with the collection cavity 201, and an exhaust pipe 203 communicating with the collection cavity 201.
[0033] The collection chamber 201 located within the plate 100 is used to collect dust. The through hole 202 is connected to the collection chamber 201. Under the action of the suction pipe 203, a negative pressure is formed inside the collection chamber 201. The dust generated during the cleaning process of the cleaning component 300 enters the collection chamber 201 through the through hole 202.
[0034] The cleaning assembly 300 includes a whetstone 301 mounted on the plate 100 and a cleaning brush 302 disposed around the whetstone 301. The whetstone 301 extends at least partially from the through hole 202, and the area of the whetstone 301 is smaller than the area of the through hole 202.
[0035] It is understood that the grinding stone 301 mounted on the plate 100 extends at least partially from the through hole 202, thereby contacting the surface of the fixture to be cleaned and cleaning the fixture during movement. The area of the through hole 202 is larger than the area of the grinding stone 301, and the grinding stone 301 cannot completely seal the through hole 202, i.e., there is a gap between the grinding stone 301 and the inner wall of the through hole 202.
[0036] The through hole 202 is connected to the collection chamber 201. The grinding stone 301 extends from the through hole 202 and has a gap between itself and the inner wall of the through hole 202. This gap serves as the inlet for dust to enter the collection chamber 201. Under the action of the suction pipe 203, a negative pressure is formed within the collection chamber 201, thereby adsorbing dust at the inlet. Thus, dust generated during the cleaning process of the grinding stone 301 enters the collection chamber 201 through the inlet, achieving dust collection. The shape of the through hole 202 can be specifically determined by the shape of the grinding stone 301.
[0037] The cleaning brush 302 is used to brush the surface of the fixture after it has been cleaned by the grinding stone 301. The dust adsorbed on the surface of the fixture will be brushed off by the cleaning brush 302, thereby preventing the dust from adsorbing on the surface of the fixture. The dust after being brushed off will then enter the collection chamber 201 through the inlet.
[0038] The cleaning brush 302 is arranged around the grinding stone 301, thereby forming a relatively enclosed space between the plate 100, the cleaning brush 302, and the fixture to be cleaned when the grinding stone 301 cleans the fixture. The grinding stone 301 cleans within this space, effectively preventing dust from spreading. Simultaneously, the cleaning brush 302 can sweep the fixture in any direction the grinding stone 301 cleans, and the cleaning action of the grinding stone 301 and the sweeping action of the cleaning brush 302 are performed simultaneously, improving cleaning efficiency.
[0039] The plate body 100 includes a substrate 101 and a cleaning plate 102 connected to the substrate 101. The collection cavity 201 is located between the substrate 101 and the cleaning plate 102. The through hole 202 is disposed in the middle of the cleaning plate 102. The cleaning brush 302 is located on the side of the cleaning plate 102 away from the substrate 101.
[0040] By setting the plate body 100 as two interconnected parts and placing the collection cavity 201 between the substrate 101 and the cleaning plate 102, that is, the substrate 101 and the cleaning plate 102 surround to form the collection cavity 201, the collection cavity 201 can be cleaned after the substrate 101 and the cleaning plate 102 are separated.
[0041] A groove 102a is provided on the side of the substrate 101 facing the cleaning plate 102 and / or on the side of the cleaning plate 102 facing the substrate 101, so that after the substrate 101 and the cleaning plate 102 are connected, the groove 102a is closed to form the collection cavity 201.
[0042] An L-shaped plate 101a for fixing the cleaning plate 102 is provided on the substrate 101. The L-shaped plate 101a is fixed to the substrate 101 by bolts, and the L-shaped plate 101a presses the cleaning plate 102 so that the cleaning plate 102 is connected to the substrate 101.
[0043] Of course, in other embodiments, bolt holes may be provided on the substrate 101 and the cleaning plate 102, so that the substrate 101 and the cleaning plate 102 can be directly fixed by bolts.
[0044] The through hole 202 is located in the middle of the cleaning plate 102 and passes through the cleaning plate 102, thereby communicating with the collection chamber 201.
[0045] The cleaning brush 302 is located on the side of the cleaning plate 102 facing away from the substrate 101, thereby brushing the surface of the fixture after it has been cleaned by the grinding stone 301. The cleaning plate 102 has a plurality of mounting holes 102b arranged around the through hole 202. The cleaning brush 302 is installed in the mounting holes 102b, allowing it to be disassembled and cleaned. The cleaning brush 302 is made of tungsten carbide.
[0046] The grinding stone 301 is fixed on the plate 100. At least part of the grinding stone 301 extends out of the through hole 202, and the area of the grinding stone 301 is smaller than the area of the through hole 202, so that there is a gap between the grinding stone 301 and the inner wall of the through hole 202. This gap is the inlet for dust to enter the collection chamber 201.
[0047] Preferably, the shape of the grinding stone 301 is the same as the shape of the through hole 202, and the center of the grinding stone 301 coincides with the center of the through hole 202.
[0048] Taking the cross-section of the grinding stone 301 as a rectangle as an example, the shape of the through hole 202 is also set as a rectangle. The area of the grinding stone 301 is smaller than the area of the through hole 202, that is, the rectangular cross-section of the grinding stone 301 is proportionally smaller than that of the through hole 202. The center of the grinding stone 301 and the center of the through hole 202 are kept coincident, and the center of the rectangle is the intersection of the two diagonals. This ensures that there are gaps between the grinding stone 301 and the four inner walls of the through hole 202, meaning the inlet is located around the perimeter of the grinding stone 301, thereby effectively collecting dust.
[0049] Of course, the cross-section of the grinding stone 301 can also be circular, and the shape of the through hole 202 is also set to be circular. The area of the grinding stone 301 is smaller than the area of the through hole 202, that is, the radius of the circular cross-section of the grinding stone 301 is smaller than the radius of the through hole 202. The center of the grinding stone 301 and the center of the through hole 202 are kept coincident, and the center of the circle is the center point. In this way, the inlet is annular, which can effectively collect dust.
[0050] The grinding stone 301 is made of high-temperature sintered alumina, zirconium oxide, etc.
[0051] The suction pipe 203 is connected to the substrate 101 and is located on the side of the substrate 101 facing away from the cleaning plate 102. The suction pipe 203 is connected to the collection chamber 201. By connecting the suction pipe 203 to an external vacuum device, a negative pressure is formed in the collection chamber 201, thereby adsorbing dust through the inlet to achieve dust collection.
[0052] The grinding stone 301 is mounted on the plate 100 by a fastener 400. The fastener 400 includes a fixing seat 401 facing the through hole 202 and a fixing groove 402 disposed in the fixing seat 401. The grinding stone 301 is mounted in the fixing groove 402.
[0053] The mounting base 401 is fixed in the position opposite to the through hole 202 by the base plate 101 and the cleaning plate 102. The fixing groove 402 is disposed in the mounting base 401 and is used to install the grinding stone 301, and the grinding stone 301 is partially located outside the fixing groove 402.
[0054] Specifically, the through hole 202 includes an inlet portion 202a and a positioning portion 202b connecting the inlet portion 202a and the collection cavity 201. The area of the positioning portion 202b is larger than the area of the inlet portion 202a, and a bearing surface 202c is formed between the inlet portion 202a and the positioning portion 202b. The fixing seat 401 includes a fixing portion 401a located within the collection cavity 201, and the fixing portion 401a abuts against the bearing surface 202c.
[0055] Reference Figure 5 Taking the through hole 202 as an example, both the inlet portion 202a and the positioning portion 202b are rectangular holes. The area of the positioning portion 202b is larger than the area of the inlet portion 202a. The size of the positioning portion 202b is proportionally larger than that of the inlet portion 202a, thereby forming the abutment surface 202c between the inlet portion 202a and the positioning portion 202b.
[0056] The height of the fixing seat 401 is equal to the sum of the height of the collection cavity 201 and the height of the positioning part 202b, so that the fixing seat 401 simultaneously abuts against the abutting surface 202c and the side of the base plate 101 facing the cleaning plate 102. That is, under the action of the base plate 101 and the cleaning plate 102, the fixing seat 401 is fixed in the position facing the through hole 202, so that the grinding stone 301 located in the fixing groove 402 extends out from the through hole 202.
[0057] The fixing part 401a includes a main body part 401a-1 and a plurality of fixing blocks 401a-2 disposed on the outer edge of the main body part 401a-1. The area of the main body part 401a-1 is smaller than the area of the inlet part 202a. The fixing blocks 401a-2 abut against the abutting surface 202c.
[0058] The cross-section of the main body 401a-1 is also rectangular. The cross-sectional area of the main body 401a-1 is smaller than the area of the inlet 202a, thereby preventing the main body 401a-1 from obstructing dust from entering the collection chamber 201 through the through hole 202.
[0059] The fixing blocks 401a-2 are positioned at the four apex corners of the main body 401a-1. The height of each fixing block 401a-2 is equal to the sum of the height of the collecting cavity 201 and the height of the positioning part 202b, thereby abutting against the supporting surface 202c. The rectangular area formed by the four fixing blocks 401a-2 is the same as the area of the positioning part 202b. All four fixing blocks 401a-2 simultaneously abut against the inner wall of the positioning part 202b, thus achieving the positioning and installation of the fixing seat 401. This ensures that the center of the fixing seat 401 coincides with the center of the through hole 202, thereby aligning the center of the grinding stone 301 with the center of the through hole 202. The height of the main body 401a-1 is less than or equal to the height of the fixing blocks 401a-2.
[0060] The fixing part 401a also includes a threaded hole 401a-3 provided on the main body part 401a-1. The threaded hole 401a-3 communicates with the fixing groove 402. The grinding stone 301 is fixed by setting a bolt in the threaded hole 401a-3 to abut against the grinding stone 301 in the fixing groove 402. Similarly, the grinding stone 301 can be replaced later.
[0061] The fixing base 401 also includes a connecting part 401b connected to the fixing part 401a. The area of the connecting part 401b is smaller than the area of the inlet part 202a, and the connecting part 401b extends out from the inlet part 202a.
[0062] The fixing groove 402 extends through the fixing part 401a and the connecting part 401b. The height of the grinding stone 301 is greater than the height of the fixing base 401, so that part of the grinding stone 301 is located outside the fixing groove 402. The connecting part 401b is used to further strengthen the firmness of fixing the grinding stone 301 and prevent the grinding stone 301 from loosening during the cleaning process.
[0063] The area of the connecting part 401b is smaller than the area of the inlet part 202a, and the connecting part 401b extends from the inlet part 202a. Therefore, the connecting part 401b cannot completely seal the inlet part 202a; that is, there is a gap between the connecting part 401b and the inner wall of the inlet part 202a. This gap is the entry point for dust to enter the collecting chamber 201.
[0064] In summary, this utility model cleans the fixture by using the grinding stone 301 extending from the through hole 202, brushing the fixture with the cleaning brush 302 to prevent dust from adhering to the surface of the fixture, and collecting the dust from the through hole 202 through the collection chamber 201, thereby preventing the dust from spreading.
[0065] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
[0066] The detailed descriptions listed above are merely specific descriptions of feasible embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. All equivalent embodiments or modifications made without departing from the spirit of the present utility model should be included within the scope of protection of the present utility model.
