Description

[Technical Field]

[0001] The present technical solution relates to the field of vacuum cleaner technology, and particularly refers to desktop vacuum cleaners. [Background technology]

[0002] In nail art operations, nail shavings and dust are inevitably generated during steps such as trimming, polishing and buffing, so desktop vacuum cleaners for nail art have been developed to mainly collect the shavings and dust and keep the desktop clean.

[0003] Chinese Patent CN202321873309.2 discloses a desktop vacuum cleaner for nail art, which includes a panel, a cover plate of an ashtray compartment, a blade partition, a fan module, a bottom shell and an ashtray, the fan module is mounted in the bottom shell, the blade partition is located above the fan module, the ashtray is installed at the upper end of the blade partition, and a removable filter paper is installed in the ashtray, i.e., the fan module is located below the ashtray, and this design uses the fan module to generate suction force, which causes dust to enter the ashtray from the panel, thereby realizing the collection of dust or shavings.

[0004] However, there are still some drawbacks, such as: the ash tray is located above or in front of the fan module (i.e., the dust collector uses a front-mounted design), and after dust is collected in the ash tray, the filter paper is easily clogged with nail shavings, reducing the dust collection efficiency; to maintain the dust collection effect, the motor speed must be increased, resulting in increased noise; and because the dust collector uses a front-mounted design, after the device stops operating, the dust and shavings in the dust collector are exposed to the air. When air currents occur in the environment, the shavings float again and accumulate on the table, reducing the cleaning effect. In this case, the dust is not effectively disposed of and remains at the tip of the vacuum cleaner, requiring the user to frequently clean during nail art services, which not only wastes time but also reduces work efficiency.

[0022] Hereinafter, specific embodiments of the present technical solution will be described in more detail with reference to the drawings, and reference will be made to FIGS.

[0023] Referring to FIGS. 1 to 4, a desktop vacuum cleaner is a case 1 in which a storage chamber 11 and a dust collection chamber 12 are installed and which has a dust suction port 111 and a dust discharge port 121 opened, the dust suction port 111 being located at the top end of the case 1 and the dust discharge port 121 being located at the bottom end of the case 1, the dust suction port 111 communicating with the storage chamber 11 and the outside, and the dust discharge port 121 communicating with the dust collection chamber 12 and the outside; At least one blower 2 is installed in the storage chamber 11, with an air intake 211 communicating with the dust suction port 111 and an exhaust port 212 communicating with the dust collection chamber 12. When multiple blowers 2 are used, the multiple blowers 2 may be arranged in the same storage chamber 11, or the storage chamber 11 may be divided into several chambers and one blower 2 may be installed corresponding to each chamber, each blower 2 having an independent housing 21, with an air intake 211 opened at the top end of each housing 21 and an exhaust port 212 at the side end of each housing 21; a filter device (3) attached to the dust outlet (121) of the dust collection chamber (12) for collecting dust; The blower 2 sucks dust from the dust suction port 111 through the air intake port 211 into the blower 2, and then discharges it into the dust collection chamber 12 through the exhaust port 212 for collection. The air can then be discharged from the case 1 through the dust discharge port 121 through the filter 3. The filter 3 filters the dust in the air, keeping it in the dust collection chamber 12, and a post-installation dust collection design is adopted.

[0024] The case 1 uses an integrated panel to create a screen mesh with a maximum pore size of 4 mm, and the screen mesh is the dust suction port 111, thereby avoiding the problem of the blower 2 being clogged by large particles of matter.

[0025] By placing the blower 2 in front, clogging at the front end does not occur, which avoids affecting the dust collection effect, and the dust collection effect can be guaranteed even with low power consumption.In addition, the dust collection effect does not decrease significantly with an increase in the amount of dust, reducing energy consumption and noise.

[0026] By exhausting from the side of the blower 2 and controlling the discharge of dust within the fixed area of ​​the filter member 32 built into the dust collection chamber 12, the ventilation of the exhaust hole 311 is ensured, and smooth exhaust is also ensured.

[0027] 5 and 6, the filtration device 3 includes: a bottom cover (31) attached to the dust outlet (121) of the case (1), covering the dust outlet (121), and having at least one exhaust hole (311) opened therein for allowing air to circulate; The filter element 32 is attached between the dust outlet 121 and the exhaust holes 311, and in the solution of this design, the filter element 32 is attached to the bottom cover 31, covers all the exhaust holes 311, and realizes dust filtration.

[0028] The filter member 32 is made of multi-layer filter cotton or HEPA filter paper. The filter member 32 is made of dust-proof sponge with a thickness of at least 1 cm and a density of 60 PPI, which makes it easy to collect dust and effectively achieves layer-by-layer filtration. It can be washed repeatedly with water, and there is no need to frequently replace the filter member 32.

[0029] The receiving chamber 11 and the dust collecting chamber 12 are arranged side by side in the case 1, that is, the receiving chamber 11 and the dust collecting chamber 12 are distributed on the left and right sides, so that the thickness of the case 1 is prevented from being too thick.

[0030] The dust collection chamber 12 adopts a five-sided sealed dustproof structure, and the bottom is provided with a dust outlet 121 and a filter member 32, which effectively controls the exhaust direction of the exhaust hole 311 to avoid direct spraying of dust onto users or customers.

[0031] The bottom cover 31 is removably attached to the dust outlet 121 of the case 1, and several first magnetic attraction members 33 are circumferentially arranged on the edge of the bottom cover 31, and the first and third magnetic attraction members 3 are magnets or magnets. Several second magnetic attraction members 13 are circumferentially arranged inside the dust outlet 121, and the second magnetic attraction members 13 are magnets or magnets. The removably attached bottom cover 31 to the case 1 is realized by the magnetic attraction connection between the first and third magnetic attraction members 3 and the corresponding second magnetic attraction members 13.

[0032] The bottom cover 31 is adapted for quick removal and quick storage by magnetic adsorption, and the filter member 32 is placed on the bottom cover 31. The bottom cover 31 and the case 1 are connected by magnetic adsorption, which increases convenience of use and avoids the reduced sealing and dust collection effect caused by using a locking method, a locking method, or an unlocking method.

The second mounting ring 35, on which the first magnetic attraction member 33 is installed, is connected to the bottom cover 31 by screws, and the stopper ring 141 is inserted into the second mounting ring 35 and movably abuts against the inner wall of the second mounting ring 35, thereby realizing a positioning function and ensuring that the bottom cover 31 is attached to the dust outlet 121 in an accurate position.

[0035] An attachment groove 351 is formed between the second attachment ring 35 and the bottom cover 31, and the edge of the filter member 32 is inserted into the attachment groove 351 to be attached, or the side wall of the attachment groove 351 presses the filter member 32, causing the filter member 32 to elastically deform, thereby achieving attachment and fixation.

[0036] Referring to FIGS. 8 to 10, the blower 2 is a housing 21 mounted in the receiving chamber 11, with an air intake 211 at the top and an air outlet 212 at the side, which draws air in from the top to create negative pressure at the top and exhausts air from the side, controlling the dust removal path and improving dust collection; and the air outlet 212 directly communicates with the dust collection chamber 12; It includes a fan 22 rotatably mounted within a housing 21; a motor mounted in the housing 21, the driving end of which is connected to the fan 22, for driving and rotating the fan 22; the connection structure between the motor and the fan 22 can be referred to in Chinese Patent CN202321873309.2, and the description thereof will be omitted here; and and a control and power supply unit 23 mounted within the case 1, electrically connected to the motor, used to provide a power source, including a circuit board, a battery, and a charging connector, including a touch-sensitive magnetic charging port, and effectively waterproof.

[0037] As shown in FIG. 7, the case 1 has an upper case 15 and a lower case 16 connected to each other by screws. The upper case 15 is provided with an installation chamber 17, a receiving chamber 11, and a dust collecting chamber 12. The installation chamber 17 is provided with a control and power supply unit 23. The electric wires of the control and power supply unit 23 pass through a relief hole in the side wall of the installation chamber 17 and are electrically connected to the blower 2. A sealant is applied between the relief hole and the electric wires. The connection between the lower case 16 and the upper case 15 is used to cover the mounting chamber 17, the receiving chamber 11 and the dust collecting chamber 12; a sealing strip 41 is installed between the edges of the lower case 16 and the upper case 15, and the sealing strip 41 can seal the mounting chamber 17 and the connection point between the lower case 16 and the upper case 15; A first sealing ring 42 is installed between the edge of the dust suction port 111 and the edge of the air intake port 211; At least one mounting port 18 is installed in the case 1, the number of the mounting ports 18 corresponds to the number of the blowers 2, the exhaust port 212 of the blower 2 is installed in the mounting port 18, the mounting port 18 connects the storage chamber 11 and the dust collection chamber 12, and a second sealing ring 43 is installed between the exhaust port 212 and the mounting port 18.

[0038] The fan 22 adopts a turbo structure and includes an integrally molded connecting cover 221, connecting bars 223, a fixing ring 224, and arc-shaped blades 225. The connecting cover 221 has a rotating shaft 222 at its center, which is rotatably disposed in a hollow rotating shaft at the bottom of the housing 21 and is connected to the driving end of the motor. Several connecting bars 223 are distributed circumferentially on the side wall of the connecting cover 221, and the connecting bars 223 are connected to the fixing ring 224. The fixing ring 224 has several arc-shaped blades 225 at at least one end, and dust passes through the gaps between the arc-shaped blades 225 to enter the dust collection chamber 12.

[0039] The motor and fan 22 are fully waterproofed to IP68 standards, the circuit board is mounted in the mounting chamber 17, the motor, fan 22 and housing 21 are in the receiving chamber 11, and the circuit board, motor and fan 22 are installed separately in different chambers. Furthermore, the dust collection and suction areas are waterproof and washable, with nano-spray waterproofing technology used for the circuit board, and the fan 22 and housing 21 also employ a sealing strip 41, a first sealing ring 42 and a second sealing ring 43 for waterproofing, with silicone gaskets used for the sealing strip 41, the first sealing ring 42 and the second sealing ring 43.

[0040] The fan 22 is IP68 rated and waterproofed to P68 standards, and the fan 22 and housing 21 are also waterproofed to P68 standards, so that after a certain amount of dust has been collected, cleaning can be achieved by rinsing with fresh water through the dust suction port 111. The cleaning process involves continuously injecting fresh water through the dust suction port 111, and when the cleaning mode of the blower 2 is turned on, the fresh water cleans the inside of the fan 22 as it rotates, and later the water is discharged into the dust collection chamber 12 through the exhaust port 212, ensuring that the inside of the dust collection chamber 12 is also cleaned.

[0041] The user can easily open the magnetically connected bottom cover 31, making it easy to clean the inside of the dust collection chamber 12, and easily disassemble the filter member 32, making the whole process quick and easy. After cleaning is complete, the filter member 32 is returned to its original position and the use mode of the blower 2 is turned on, and the blower 2 dries the inside of the vacuum cleaner with the fan 22.
