[0057] Example

[0058] See also Figure 1-Figure 4 In this embodiment, a nail cleaning vacuum device is provided, comprising:

[0059] A power module 100 is used to generate an airflow for sucking dust;

[0060] The filter element 200 is used to filter dust in the air flow;

[0061] A collecting part 300, for collecting dust;

[0062] The filter element 200 is located above the collecting portion 300 , and the air inlet side 210 faces the collecting portion 300 .

[0063] The power module 100 includes a fan. The filter element 200 includes a filter screen and the like.

[0064] like Figure 3 and Figure 4 As shown, the filter element 200 includes an air inlet side 210 and an air outlet side 220, and the air flow passes through the air inlet side 210 and the air outlet side 220 in sequence to pass through the filter element 200. The air outlet side 220 faces the power device.

[0065] During the dust collection process, the airflow generated by the power module 100 will absorb the dust in the environment, and when the airflow passes through the filter element 200, the dust in the airflow will be filtered.

[0066] Since the filter element 200 is located above the collecting portion 300, and the air inlet side 210 of the filter element 200 faces the collecting portion 300, the filtered dust will fall onto the collecting portion 300 due to its own gravity. In this way, not only can the risk of the filter element 200 being blocked be reduced, but also the dust can be effectively collected for cleaning.

[0067] In this embodiment, the power module 100 is disposed in a housing 400, and a support member 600 is disposed on the top of the housing 400, and the support member 600 is used to support the user's hand. The support member 600, the power module 100, the filter 200 and the collection part 300 are disposed in sequence from top to bottom.

The support member 600 is detachably connected to the housing 400. Specifically, the support member 600 and the housing 400 may be connected by magnetic connection, screw connection, clamping connection, etc.

[0069] like Figure 5-Figure 7As shown, the housing 400 is provided with an air inlet 401 and an exhaust part 402, and the interior of the housing 400 is provided with a circulation space 403 and an installation space 404. The collecting part 300 is located at the bottom of the circulation space 403, and the power module 100 is installed in the installation space 404. After the power module 100 is started, the airflow passes through the air inlet 401, the circulation space 403, the filter element 200, the installation space 404 and the exhaust part 402 in sequence, and is discharged outside the housing 400.

[0070] The air inlet portion 401 and the air outlet portion 402 include a hole structure, wherein the specific shape of the hole structure can be set as required.

[0071] The housing 400 includes a main body 410 .

[0072] like Figure 8 As shown, the main body 410 includes a first component 411, a second component 412 and a third component 413 which are connected in sequence. The second component 412 is located at the top of the housing 400, and the support member 600 is disposed on the second component 412. The first component 411 is provided with an air inlet 401, and the air inlet 401 is connected to the circulation space 403.

[0073] like Fig. 9 As shown, in this embodiment, a protective net 700 is provided on the inner wall of the first component 411, and the protective net 700 covers the air inlet 401, thereby isolating non-small particle objects (such as paper pieces, etc.) and preventing such objects from being sucked into the circulation space 403 and causing blockage of the filter element 200, etc.

[0074] The protection net 700 includes a grid 710 , which is fixedly connected to the first component 411 , for example, by bonding, clamping, screw connection, etc. A connecting piece 720 may be provided on the grid 710 , and the connecting piece 720 abuts against the first partition plate 510 of the bracket 500 .

[0075] The first component 411, the second component 412 and the third component 413 may all be plate-shaped structures. The first component 411, the second component 412 and the third component 413 may be made of metal or plastic. Specifically, the first component 411, the second component 412 and the third component 413 may be an integrated structure.

[0076] like Fig.10As shown, in this embodiment, the angle between the outer surfaces of the first component 411 and the second component 412 is a; the angle between the outer surfaces of the second component 412 and the third component 413 is b; 180°<a<270°, 180°<b<270°. When the housing 400 is placed on a horizontal plane, the outer surface of the third component 413 is perpendicular to the horizontal plane.

[0077] In some embodiments, a is 190°, 200°, 215°, etc., and b is 195°, 223°, 268°, etc.

[0078] Reference Figure 7 , the shell 400 is placed on a horizontal table, and at this time, the outer surface of the third component 413 is perpendicular to the horizontal plane. When the user is doing manicure, the hand will be placed on the support 600; due to the existence of angle b, it can play a role in raising the user's hand, so as to facilitate the operation of the manicurist; due to the existence of angle a, when the user's fingers naturally droop, the outer surface of the first component 411 can play a role in supporting the fingers, thereby improving comfort. Since the air inlet 401 is arranged on the first component 411, the dust generated during manicure can be quickly sucked into the shell 400.

[0079] like Figure 5-Figure 7 As shown, the housing 400 further includes a first side portion 420 , a second side portion 430 and a base 440 .

[0080] The first side portion 420 and the second side portion 430 are respectively installed on both sides of the main body 410, and the first side portion 420 and the second side portion 430 are fixedly connected to the base 440. An extension portion 4111 is provided at one end of the first component 411 away from the second component 412, and the extension portion 4111 is fixedly connected to the base 440.

[0081] The nail art vacuuming device further includes a cushion 800, which can be fitted with the outer surface of the extension portion 4111. When performing nail art, the cushion 800 can support the fingertips of the user.

[0082] An exhaust portion 402 is disposed on the first side portion 420 and / or the second side portion 430 , wherein the exhaust portion 402 is in communication with the installation space 404 . The exhaust portion 402 is used to exhaust the filtered airflow to the outside of the housing 400 .

[0083] In this embodiment, the exhaust portion 402 is disposed on both the first side portion 420 and the second side portion 430. In other embodiments, the exhaust portion 402 may be disposed on the first side portion 420 or the second side portion 430.

[0084] The collecting portion 300 and the base 440 are detachable, thereby facilitating the cleaning of the collected dust.

[0085] like Fig.11 As shown, a handle structure 310 may be provided on the collecting portion 300 .

[0086] like Fig.12 As shown, there is an opening 450 between the third component 413 and the base 440, and the opening 450 is used for the collection part 300 to pass through. Figure 6 and Figure 7 The opening 450 is detachably provided with a cover 451, and the cover 451 is used to close the opening 450. The cover 451 can be connected to the third component 413 by magnetic connection, clamping connection, screw connection, etc.

[0087] like Fig.13 As shown, the cover 451 has a fitting portion 4511, which has a function of installation and positioning. When the cover 451 is assembled with the housing 400, the fitting portion 4511 fits with the bottom surface of the base 440.

[0088] When the collecting part 300 needs to be cleaned, the lower cover 451 is removed to expose the opening 450. Then, the collecting part 300 can be pulled out from the base 440 by placing a finger on the handle structure 310. After the collecting part 300 is cleaned, the collecting part 300 is inserted back into the base 440 through the opening 450, and then the upper cover 451 is installed.

[0089] like Fig.14 As shown, a bracket 500 is disposed inside the housing 400. The bracket 500 is used to separate the space inside the housing 400 to form a circulation space 403 and an installation space 404. In order to improve the sealing performance, the first side portion 420 and the second side portion 430 are both fitted with the bracket 500 during assembly.

[0090] like Fig.15 and Fig.16 As shown, in this embodiment, the power module 100 and the filter element 200 are both fixed on the bracket 500. The bracket 500 is provided with a through hole 501, wherein the power module 100 is opposite to the air outlet side 220 through the through hole 501.

[0091] like Fig.17 As shown, the bracket 500 includes a first partition plate 510 and a second partition plate 520 connected to each other. The first partition plate 510 and the second partition plate 520 can be an integrated structure and can be formed by metal or plastic.

[0092] The power module 100 and the filter element 200 are both fixed on the second partition plate 520 , and correspondingly, the through hole 501 is opened on the second partition plate 520 .

[0093] Reference Fig.14The first partition plate 510 is arranged opposite to the first component part 411, and a first gap 531 is provided between the first partition plate 510 and the first component part 411; the second partition plate 520 is arranged opposite to the collecting part 300, the filter element 200 is arranged on the side of the second partition plate 520 facing the collecting part 300, and a second gap 532 is provided between the filter element 200 and the collecting part 300.

[0094] The airflow containing dust flows into the circulation space 403 through the air inlet 401: some dust will enter the first compartment 531; due to the effect of inertia, some dust flowing into the first compartment 531 will collide with the first partition 510 and fall on the collecting part 300 along the first partition 510, thereby reducing the filtering pressure of the filter element 200; another part of the dust will flow into the second compartment 532 with the airflow, and the dust in the airflow will be filtered under the action of the filter element 200. Among them, due to the effect of its own gravity, some dust attached to the filter element 200 will fall on the collecting part 300, thereby reducing the risk of the filter element 200 being blocked.

[0095] like Fig.17 As shown, the first partition 510 includes a first end portion I511 and a first end portion II512 disposed at both ends, and the second partition 520 includes a second end portion I521 and a second end portion II522 disposed at both ends. The first end portion II512 is connected to the second end portion I521. In this embodiment, since the first partition 510 and the second partition 520 are an integrated structure, the first end portion II512 and the second end portion I521 are actually connected as one body.

[0096] Reference Fig.14 and Fig.17 In the direction from the first end I511 to the first end II512, the distance between the first partition 510 and the first component 411 gradually increases, so that more dust can automatically fall on the collecting part 300 under the action of the first partition 510, and ensure that the airflow can flow smoothly into the second interval 532; in the direction from the second end I521 to the second end II522, the distance between the filter element 200 and the collecting part 300 gradually decreases, so that the airflow can flow smoothly into the second interval 532, and at the same time, the flow rate of the airflow close to the second end II522 is increased, thereby improving the filtration efficiency.

[0097] The first end portion I511 is provided with a first connection portion 541, and the first connection portion 541 is fixedly connected to the second component portion 412, for example, by clamping, screwing, etc. The second end portion II522 is provided with a second connection portion 542, and the second connection portion 542 is fixedly connected to the third component portion 413, for example, by clamping, screwing, etc. With the above-mentioned structural arrangement, the connection between the bracket 500 and the main body 410 can be achieved.
