Description

Technical Field

[0001] This technical solution relates to the field of vacuum cleaner technology, specifically a vacuum cleaner for nail polishing. Background Technology

[0002] A nail vacuum cleaner is a small device used to absorb dust during nail trimming, polishing, and filing. It uses an internal fan to generate suction, sucking in dust and debris and trapping them in a filter.

[0003] For example, Chinese patent CN209135580U discloses a nail vacuum cleaner, which includes a vacuuming device. The vacuuming device includes a vortex fan and a dust collection box. The upper shell has multiple dust inlets, and the side wall of the lower shell has multiple air outlets. The air inlet of the vortex fan is connected to the dust inlets. An arc-shaped air duct is provided on the inner wall of the lower shell. One end of the arc-shaped air duct is connected to the air outlet of the vortex fan. The dust collection box includes a box body and multiple vertically spaced filter sheets. The top of the dust collection box is provided with an adsorption layer made of activated carbon fiber.

[0004] The aforementioned nail vacuum cleaner uses a vortex fan as its suction power source. Its air outlet needs to be aligned with the dust inlet of the polishing area and arranged vertically in order to discharge the sucked-in dust along the side air duct into the dust collection box. This results in a tortuous airflow path. In addition, traditional turbine fans have high single-point wind pressure, but their effective air volume is limited, resulting in insufficient suction power and difficulty in completely absorbing scattered particles. The dust collection effect is poor and needs to be improved. Summary of the Invention

[0005] This technical solution aims to improve the problem of insufficient suction and poor dust collection effect caused by the limited air volume of traditional turbine fans, and provides a vacuum cleaner for nail polishing.

[0006] The purpose of this technical solution is achieved as follows: A vacuum cleaner for nail polishing includes: The box body has an internal cavity, and the top of the box body is provided with a mesh cover; A dust collection box, which is located on the side of the box body, is used to collect impurities; A flow guide hood is installed inside the box cavity. The flow guide hood has a flow guide channel, which has a dust inlet connected to a mesh cover and a dust outlet connected to a dust collection box. At least one axial fan is provided at the dust outlet. When the axial fan is running, impurities are drawn into the guide channel through the mesh cover at the dust inlet and discharged into the dust collection box through the axial fan at the dust outlet.

[0007] Through the above technical solution, when a nail polishing vacuum cleaner is in normal use, the axial fan generates strong airflow. The impurities generated during polishing are sucked in through the mesh cover on the box and enter the guide channel through the dust inlet on the guide cover. The impurities flow in the channel and are finally efficiently discharged into the dust collection box on the side through the dust outlet. Multiple fans are arranged side by side at the dust outlet, which further multiplies the airflow without increasing the overall thickness of the device, achieving an optimized balance between vacuuming efficiency and device size. Compared with traditional turbine fans, the axial fan can provide stronger airflow and improve the vacuuming effect.

[0008] Preferably, the axial airflow direction of the axial fan at the dust outlet is perpendicular to the airflow direction from the dust inlet to the guide channel.

[0009] Through the above technical solution, the core features of the axial flow fan are axial air intake and axial air exhaust. The airflow channel provides an airflow channel. This channel is L-shaped, which can reasonably arrange components such as dust collection box and axial flow fan on different sides of the equipment. Multiple axial flow fans can be arranged side by side at the dust outlet, optimizing the overall size and shape of the entire product.

[0010] Preferably, the inner wall of the flow guiding channel has a guide arc surface.

[0011] Through the above technical solutions, the arc surface can effectively guide the airflow direction, reduce the collision and friction between impurity particles and the channel wall, and compared with the vertical structure, it eliminates the dead corners where dust is trapped, reduces the flow resistance of airflow in the channel, reduces the loss of airflow energy, and improves the overall dust collection efficiency.

[0012] Preferably, the box body includes a shell and a matching box base, the shell having an opening one corresponding to the dust inlet and an opening two corresponding to the dust outlet; The shell has several snap-fit ​​strips extending into the cavity along the opposite sides of the opening. Each snap-fit ​​strip has a snap-fit ​​part protruding from it. The inner wall of the flow guide has snap-fit ​​protrusions that are fitted into the snap-fit ​​parts.

[0013] With the above technical solution, opening one and opening two correspond to the inlet and outlet of the airflow channel. Several snap-fit ​​strips on the housing are aligned with the dust inlet of the guide hood and inserted. The snap-fit ​​protrusions on the inner wall of the guide hood will automatically correspond and fit with the protruding snap-fit ​​parts on the snap-fit ​​strips. Then, the housing and the box base are fixedly installed, and the guide hood can be installed in the box cavity. This simplifies the installation and disassembly process of the guide hood and improves the assembly efficiency and stability of the equipment.

[0014] Preferably, the housing is formed with a mounting annular groove around the edge of the opening, and the mesh cover is separately engaged in the mounting annular groove.

[0015] With the above technical solution, the mesh cover is firmly abutted against the bottom of the mounting ring groove by its edge, which simplifies the daily cleaning and maintenance process, such as removing blockages or replacing the mesh cover, and enables quick, tool-free disassembly and assembly of the mesh cover, thus improving convenience.

[0016] Preferably, two quick-release structures are symmetrically arranged between the box body and the dust collection box, and each quick-release structure includes: A buckle strip is provided on the side wall of the housing, and the buckle strip has buckle protrusions; The locking part, whose corresponding position to the buckle strip protrudes from the inner side wall of the dust collection box; A sliding switch is slidably disposed on the side wall of the dust collection box. The sliding switch includes a switch slider and an unlocking top piece disposed on the switch slider. The unlocking top piece has a pushing part. When the buckle protrusion engages with the locking part, the quick-release structure is in a locked state. By moving the sliding switch, the unlocking top piece slides, and the pushing part pushes against the buckle strip, causing the buckle protrusion to disengage from the locking part, thus switching the quick-release structure to the unlocked state.

[0017] With the above technical solution, when installing the dust collection box, align it with the side wall of the box body and press it slightly. This will cause the locking part on the inner side wall of the dust collection box to automatically engage with the buckle protrusion on the buckle strip on the side wall of the housing. The quick-release structure will then simultaneously enter the locked state, ensuring that the dust collection box is securely installed. When disassembling, simply use your fingers to simultaneously move the sliding switches on both sides of the dust collection box, causing the switch slider and its unlocking top to slide. The pushing part of the unlocking top will then push against the buckle strip, causing it to elastically deform and the buckle protrusion to instantly disengage from the locking part. The quick-release structure will then switch to the unlocked state, allowing you to easily remove the dust collection box for separate cleaning and replacement with a new dust collection box. This method is suitable for high-intensity work and improves work efficiency.

[0018] Preferably, the switch slider is provided with a hook, the dust collection box is provided with a groove, and the switch slider is limited in the groove by the hook and slides along the groove; The unlocking top piece has a slot for engaging with the hook.

[0019] By using the above technical solution, the sliding switch is assembled, and the hooks elastically close and embed into the slots. The hooks then engage the unlocking piece, thus achieving a quick and stable connection between the switch slider and the unlocking top piece.

[0020] Preferably, the dust collection box is provided with a plug-in part, and the box body is provided with a plug-in groove that matches the plug-in part.

[0021] With the above technical solution, when the dust collection box is installed on the box body through the quick-release structure, the plug part needs to be plugged into the plug slot accordingly to complete the initial positioning and guidance between the dust collection box and the box body, realize the pre-positioning of the dust collection box, reduce the difficulty of operation, enhance the vertical pressure resistance, and improve the stability of the connection.

[0022] Preferably, the dust collection box is provided with an installation groove, and a filter element is installed in the installation groove; The dust collection box has several ventilation holes, all of which are connected to the mounting slot to the outside.

[0023] Through the above technical solution, the filter element is modularly installed in the mounting slot. It can be made of materials such as sponge, HEPA filter or multi-stage filter assembly, and is used to adsorb impurities and fine dust sent out by the axial flow fan.

[0024] Through the above technical solution, after the filter element adsorbs impurities, the ventilation holes provide an exhaust channel for the filtered airflow and balance the air pressure inside the dust collection box.

[0025] Preferably, the housing is equipped with an adjustment switch, which is electrically connected to the axial fan for adjusting the airflow.

[0026] Through the above technical solution, users can steplessly or steppedly adjust the axial fan speed (i.e., wind force) by rotating the adjustment switch in different directions, thereby improving the adaptability and flexibility of the equipment to different cleaning tasks.

[0027] The key and beneficial technical effects of this technical solution compared to existing technologies are: 1. This technical solution installs one or more axial fans at the dust outlet of the airflow channel. The strong airflow of the axial fans draws the impurities generated during grinding from the mesh cover into the airflow channel and finally discharges them into the dust collection box. Its compact structure also avoids increasing the overall thickness, achieving an optimized effect of efficient dust collection in a limited space and improving suction power and dust collection efficiency.

[0028] 2. This technical solution features two quick-release structures symmetrically arranged between the box body and the dust collection box. With a press-type automatic buckle locking and a double-sided sliding switch unlocking design, pressing securely locks the box during installation. During disassembly, a two-finger toggle switch triggers the push mechanism to release the buckle and complete the separation, enabling quick installation and disassembly of the dust collection box. This ensures efficient dust collection box replacement during high-intensity operations, allowing for independent cleaning or replacement without tools, thus improving work smoothness and efficiency.

[0031] The specific implementation of this technical solution will be further described in detail below with reference to the accompanying drawings.

[0032] Example: See Figure 1 and Figure 3 A vacuum cleaner for nail polishing includes a box body 1, a dust collection box 4, and a flow guide hood 5. The box body 1 includes a shell 11 and a box seat 12 that matches the shell 11. The shell 11 covers the box seat 12 and the two are connected by bolts. A box cavity 2 is formed between the box body 1 and the box seat 12.

[0033] The box body 1 is provided with a mesh cover 3. The upper end face of the shell 11 has an opening 91, which connects the box cavity 2 to the outside. The shell 11 also has an installation ring groove 14, which surrounds the edge of the opening 91 and is formed on the outside of the opening 91. The box body 1 is provided with a mesh cover 3, which has a number of mesh holes. The mesh cover 3 is installed at the opening 91 that is adapted to it. Its edge is embedded in the installation ring groove 14, and the edge part abuts against the bottom of the installation ring groove 14. The mesh cover 3 can be quickly and tool-free installed and removed.

[0034] The flow guide hood 5 has a flow guide channel 6, which is respectively formed with a dust inlet 61 connected to the mesh cover 3 and a dust outlet 62 connected to the dust collection box 4. The dust inlet 61 is formed on the upper end face of the flow guide hood 5, and its opening size matches the opening 91. The dust outlet 62 is formed on the side of the flow guide hood 5. The shell 11 and the box base 12 are spliced ​​together to leave an opening 92. The opening 92 is correspondingly set with the dust outlet 62 and the opening size matches the opening. The inner wall of the flow guide channel 6 has a guide arc surface 8, which is used to guide the airflow direction of the dust inlet 61 to the dust outlet 62.

[0035] The size of the flow guide shroud 5 is smaller than that of the box cavity 2. It is installed inside the box cavity 2 and is fixedly connected to the housing 11. Specifically, the flow guide shroud 5 has several symmetrically protruding snap-fit ​​parts 13 on the opposite inner sidewalls near the dust inlet 61. In this embodiment, six snap-fit ​​parts 13 are shown, that is, three snap-fit ​​parts 13 are arranged at intervals on each inner sidewall. The housing 11 has six snap-fit ​​strips 101 extending into the box cavity 2 along the opposite sides of the opening 91. The positions of the six snap-fit ​​strips 101 correspond one-to-one with the six snap-fit ​​parts 13. Each strip 101 has a snap-fit ​​protrusion 102 protruding outwards, and the snap-fit ​​strip 101 has a certain deformation capability. By aligning the snap-fit ​​strips 101 of the housing 11 with the dust inlet 61 of the guide shroud 5, the snap-fit ​​strips 101 deform so that the snap-fit ​​protrusions 102 pass through the snap-fit ​​parts 13. The snap-fit ​​protrusions 102 automatically engage and abut against the snap-fit ​​parts 13 one by one, thereby restricting the separation of the guide shroud 5 from the housing 11. Then, the housing 11 and the box base 12 are fixedly installed, and the guide shroud 5 can be installed in the box cavity 2, simplifying the installation and disassembly process of the guide shroud 5.

[0036] It also includes one or more axial flow fans 7, which are installed at the dust outlet 62 of the air guide shroud 5. In this embodiment, three axial flow fans 7 are arranged side by side. The three axial flow fans 7 are integrated into the fan housing. Their overall volume matches the dust outlet 62. Their overall height is the height of one axial flow fan 7, and their overall length is the width of three axial flow fans 7. By increasing the number of axial flow fans 7, the air volume can be increased without increasing the overall thickness of the equipment. First, the three axial flow fans 7 are snapped into the dust outlet 62, and then bolts are passed through the through holes of the air guide shroud 5 and screwed into the corresponding threaded holes of the axial flow fans 7.

[0037] The housing 11 is equipped with an adjustment switch 25, which is fixed to the side wall of the housing 11. The adjustment switch 25 is electrically connected to the axial flow fan 7. By rotating the adjustment switch 25 in different directions, the wind force of the axial flow fan 7 can be adjusted. When the adjustment switch 25 is rotated in the first direction, the power of the axial flow fan 7 is increased to enhance the wind force. When the adjustment switch 25 is rotated in the opposite second direction, the power of the axial flow fan 7 is decreased to weaken the wind force, thereby improving the adaptability and flexibility of the equipment to different cleaning tasks. The axial flow fan 7 draws impurities from the mesh cover 3 into the guide channel 6 through the dust inlet 61 and discharges them into the dust collection box 4 through the dust outlet 62.

[0038] See Figure 4 The dust collection box 4 has an installation groove 22 located at the bottom of the dust collection box 4. A baffle is formed by protruding strips on the inner wall of the dust collection box 4. A matching filter element 23 is installed in the installation groove 22 and is confined within the installation groove 22. The filter element 23 is preferably made of sponge, HEPA filter or multi-stage filter assembly, etc., to adsorb impurities and fine dust (particles after nail polishing) sent out by the axial fan 7.

[0039] The bottom of the dust collection box 4 has one or more ventilation holes 24, all of which are connected to the mounting groove 22 to the outside. After the filter element 23 adsorbs impurities, the ventilation holes 24 provide an exhaust channel for the filtered airflow and balance the air pressure inside the dust collection box 4.

[0040] See Figure 2 The dust collection box 4 is provided with a plug-in part 20, which is formed on the edge of the opening of the dust collection box 4. The box body 1 is provided with a plug-in groove 21 that matches the plug-in part 20. The plug-in part 20 can be inserted into the plug-in groove 21 to improve the connection strength and firmness between the two and prevent easy breakage.

[0041] See Figure 5 , Figure 6 and Figure 7 Two quick-release structures 15 are symmetrically arranged between the box body 1 and the dust collection box 4. Each quick-release structure 15 includes a buckle strip 151, a locking part 152, and a sliding switch 153. The opposite side walls of the dust collection box 4 are provided with a sliding groove 26, which extends from the inside to the outside of the dust collection box 4. The sliding switch 153 is slidably installed in the sliding groove 26. The sliding switch 153 includes a switch slider 1531 and an unlocking top piece 1532. The switch slider 1531 is provided with a hook 18, which is fixed to the inside of the switch slider 1531. The hook 18 usually includes two deformable parts close to the hook part. The unlocking top piece 1532 is provided with a slot 19. The side of the switch slider 1531 with the hook 18 is inserted into the sliding groove 26, and then the slot 19 is aligned with the hook 18 to engage, so that the unlocking top piece 1532 and the switch slider 1531 are fixedly connected. The sliding switch 153 moves horizontally back and forth along the groove 26.

[0042] Two locking parts 152 protrude from the opposite inner sidewalls of the dust collection box 4. One end of the locking strip 151 is fixed to the bottom of the insertion slot 21, and the other end extends toward the dust collection box 4. The outer side of the locking strip 151 has a locking protrusion 16. The positions of the two locking strips 151 correspond one-to-one with the two locking parts 152. When installing the dust collection box 4, the insertion part 20 of the dust collection box 4 is aligned with the insertion slot 21 and fitted. With a slight press, the locking part 152 on the inner sidewall of the dust collection box 4 automatically engages with the locking protrusion 16 on the locking strip 151 on the sidewall of the housing 11, and the quick-release structure 15 simultaneously enters the locked state.

[0043] Each unlocking top piece 1532 has a pushing part 17, which protrudes from the side of the corresponding unlocking top piece 1532 near the opening of the dust collection box 4 and can abut against the corresponding buckle strip 151. By tossing the sliding switch 153, the switch slider 1531 and the unlocking top piece 1532 on it are moved. The pushing part 17 of the unlocking top then pushes against the buckle strip 151, and the buckle strip 151 undergoes elastic deformation, causing the buckle protrusion 16 to instantly disengage from the buckle part 152. The quick-release structure 15 is then switched to the unlocked state. At this time, the dust collection box 4 can be removed and a new dust collection box 4 can be quickly replaced. This is suitable for high-intensity work and improves work efficiency.

[0044] The specific work process of this plan is as follows: This technical solution utilizes the strong airflow generated by the axial fan 7 during operation. Impurities generated during grinding are sucked in through the mesh cover 3 on the housing 1 and enter the flow channel 6 through the dust inlet 61 on the guide cover 5. The impurities flow within the channel and are finally efficiently discharged into the dust collection box 4 on the side through the dust outlet 62. Multiple fans are arranged side by side at the dust outlet 62, further increasing the airflow without increasing the overall thickness of the equipment, thus achieving an optimized balance between dust collection efficiency and equipment size. Compared with traditional turbine fans, the axial fan 7 can provide stronger airflow and improve the dust collection effect.

Those skilled in the art should understand that this technical solution is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this technical solution.
