Description

Technical Field

[0001] This utility model relates to a dust collection container, and more particularly to a dust collection box that facilitates filter disassembly and assembly. Background Technology

[0002] Dust collection devices are typically used in conjunction with power tools. For example, power tools generate dust and debris during drilling operations. By connecting the dust collection device to the power tool, it absorbs the dust and debris generated during operation, preventing environmental pollution. A dust collection device generally consists of a main dust collection body and a dust collection box inserted into the main body. The dust collection box has an inlet for dust intake and an outlet for air exhaust. A filter is installed in the dust collection box, blocking the air flowing out of the outlet and filtering the dust particles, thus trapping them inside the dust collection box.

[0003] For example, the dust collector disclosed in patent CN211681908U includes a dust collection box assembly. The dust collection box assembly includes a base, a filter paper assembly, and a dust collection box. The base is connected to the dust collection box and can form a receiving cavity that can accommodate the filter paper assembly. The filter paper assembly includes filter paper and a fixing member. The filter paper is fixed into a whole by the fixing member. The fixing member has multiple buckles. The filter paper assembly is housed in the receiving cavity, and the fixing member can form a buckle connection with the inner surface of the base. The fixing member is a plastic part.

[0004] The existing filter paper assembly is fastened to the inner surface of the base by clips and is housed in the cavity formed between the base and the dust collection box. When it is necessary to install or remove the filter paper assembly, the base must be removed from the dust collection box before the filter paper assembly can be installed or removed. This is complicated and inconvenient. Utility Model Content

[0005] To address the issue that the filter paper assembly requires the base to be removed from the dust collection box before it can be disassembled, which is cumbersome and inconvenient, this invention provides a dust collection box that facilitates filter assembly and disassembly.

[0020] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0021] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0022] Figures 1-7 As shown, the dust collection box, which facilitates the disassembly and assembly of the filter, includes a box body 1, a top cover 2, and a filter 4. The top cover 2 is mounted on the shell and forms a dust collection chamber 8 with the box body 1. The top cover 2 is provided with an exhaust port 17 and an air inlet 5 that communicate with the dust collection chamber 8. The air inlet 5 is used for external air to enter the dust collection chamber 8, and the exhaust port 17 is used for air to be drawn out of the dust collection chamber 8.

[0023] Figure 5 As shown, the top cover 2 is fixedly connected to the housing by screws.

[0024] Figures 1-4 , Figure 6 As shown, slots 16 are provided on both sides of the exhaust port 17. The filter 4 includes a mounting bracket 27 and filter paper 13 for filtering. The filter paper 13 is fixed on the mounting bracket 27. The mounting bracket 27 is made of an elastic and deformable material. The mounting bracket 27 can be deformed by external force and then inserted into the slots 16 on both sides so that the filter 4 covers the exhaust port 17. The filter 4 filters the air drawn out from the exhaust port 17 so as to retain the dust particles in the air in the dust collection chamber 8.

[0025] The operating steps are as follows: During installation, squeeze the two sides of the mounting bracket 27 towards the center by hand, causing the mounting bracket 27 to elastically deform and narrow towards the center so that the mounting bracket 27 can be positioned between the two slots 16. Then release the squeezed mounting bracket 27, and the mounting bracket 27 will elastically return to its original position and open to both sides to fit into the slots 16 on both sides, thus completing the installation of the filter 4. During disassembly, squeeze the two sides of the mounting bracket 27 towards the center by hand, causing the mounting bracket 27 to elastically deform and narrow towards the center so that the two sides of the mounting bracket 27 disengage from the slots 16. At this time, the filter 4 can be removed from the top cover 2.

[0026] This structure eliminates the need to remove the top cover 2 from the box 1 when assembling or disassembling the filter 4. The filter 4 can be directly deformed by squeezing and then installed onto or removed from the top cover 2, making assembly and disassembly simple and convenient.

[0027] Preferably, the mounting bracket 27 is made of rubber.

[0028] The filter paper 13 is connected to the lower part of the mounting bracket 27. When the mounting bracket 27 is inserted into the slots 16 on both sides, the filter paper 13 is inserted into the dust collection chamber 8 from the exhaust port 17. In the installed state of the filter 4, the filter paper 13 is contained in the dust collection chamber 8.

[0029] A groove 3 is provided on the outer surface of the top cover 2. The exhaust port 17 is located at the bottom of the groove 3. The groove walls on both sides of the groove 3 are provided with inwardly protruding baffles 15. The baffles 15 and the bottom of the groove 3 form a slot 16 for engaging with the mounting bracket 27. The mounting bracket 27 includes an annular outer frame 11. A through hole 21 for air to pass through is formed on the inner side of the outer frame 11. The filter paper 13 is connected to the bottom of the outer frame 11 to cover the opening at the bottom of the through hole 21. When the filter 4 is installed on the top cover 2, the outer frame 11 is placed in the groove 3 and rests on the bottom of the groove 3. The two sides of the outer frame 11 are respectively engaged in the slots 16 on both sides of the groove 3. At this time, the air inside the dust collection chamber 8 is filtered by the filter paper 13 and enters the through hole 21, and then is sucked away from the through hole 21.

[0030] The structure of the groove 3 and the outer frame 11 facilitates the positioning of the filter 4. The outer frame 11 is a square frame, and the groove 3 is a square groove.

[0031] Alternatively, the thickness of the outer frame 11 can be set to be slightly thicker than the width of the card slot 16, so that the outer frame 11 and the card slot 16 fit tightly together when inserted into the card slot 16, avoiding relative movement between the two.

[0032] Figure 3 As shown, a first sealing protrusion 18 is provided on the lower surface of the outer frame 11. When the filter 4 is installed on the upper cover 2, the first sealing protrusion 18 is inserted into the exhaust port 17 and fits against the four sides of the exhaust port 17. The outer frame 11 and the groove 3 cooperate, and the first sealing protrusion 18 fits tightly against the four sides of the exhaust port 17 to ensure a sealed connection between the outer frame 11 and the exhaust port 17.

[0033] The upper surface of the outer frame 11 is provided with a second sealing protrusion 14. When the filter 4 is installed on the upper cover 2, the second sealing protrusion 14 protrudes out of the groove 3. When the dust collection box is installed on the dust collection device, the second sealing protrusion 14 can press tightly against the dust collection device so that the opening on the dust collection device is sealed to the through hole 21.

[0034] Figure 2 , Figure 6 As shown, the filter paper 13 is repeatedly folded up and down to form pleats and is attached to the mounting frame 27. This arrangement allows the pleats formed by the folding of the filter paper 13 to open outwards when the mounting frame 27 is bent and deformed by external force, making it easier to clean the dust inside the filter paper 13.

[0035] Figure 6 , Figure 7As shown, the outer frame 11 includes a front frame 23, a rear frame 25, a left frame 24, and a right frame 6. These frames form the through hole 21. The filter paper 13, which is repeatedly folded up and down, has its two ends connected to the front frame 23 and the rear frame 25, respectively. The two sides of the upper fold 26 of the filter paper 13 are connected to the left frame 24 and the right frame 6, respectively. The filter paper 13 includes multiple continuous V-shaped filter paper units 7. Side openings 22 are formed on both sides of each filter paper unit 7. Elastically deformable sealing edges 19 are provided on the left frame 24 and the right frame 6. The sealing edges 19 are connected to the side openings 22 formed on both sides of the filter paper unit 7, sealing the side openings 22 so that the filter paper 13 covers the opening at the bottom of the through hole 21. The sealing edges 19 are integrally formed with the outer frame 11 and are made of the same material.

[0036] The mounting bracket 27 includes a crossbeam 12 located inside the outer frame 11. The two ends of the crossbeam 12 are respectively connected to the middle of the front side frame 23 and the rear side frame 25. The filter paper unit 7 includes two folded edges 9. A spacer edge 10 is fixed on the crossbeam 12 and connected between the two folded edges 9 of the filter paper unit 7. The spacer edge 10 is spaced between the two folded edges 9 and is elastically deformable. It is supported at both ends of the filter paper unit 7 by the aforementioned sealing edge 19 and supported at the middle of the filter paper unit 7 by the spacer edge 10, so that the filter paper unit 7 has better three-dimensionality, facilitates air passage, and prevents the folded filter paper 13 from sticking together.

[0037] The top of the crossbeam 12 has a protrusion 20 made of the same material.

[0038] The outer frame 11, crossbeam 12, edge banding 19, protrusion 20 and spacer 10 are all integrally formed and made of the same material.
