Description

Technical Field

[0001] The invention relates to the technical field of ventilation devices, and in particular to an air purifier. Background Art

[0002] There are harmful and dangerous factors in the working environment of manicurists, such as dust, volatile harmful substances and chemicals in the air of the working area, and visual fatigue caused by insufficient lighting in the workplace. In addition, the special feature of the manicurist's workplace is that it is small in size and is mostly located in the corridors of large shopping malls, stores, and office buildings, which makes it difficult to provide air ventilation by the ventilation system equipped in the building. In order to reduce the impact of harmful factors, the harmful factors must be eliminated in whole or in part. These problems can be solved by using personal respiratory protective equipment and placing additional lighting equipment in the workplace. However, the use of personal respiratory protective equipment at work will bring certain inconveniences and cannot guarantee the protection of the manicurist's customers.

[0003] In the process of manicure, a large amount of dust and chemical fumes will be generated during nail polishing and removing the cuticle, and harmful aerosols and particles will be generated during the process of drying nails. Air purifiers can purify the air in the environment of manicure and pedicure. At present, air purifiers used in manicure and pedicure environments usually only filter the air through a filter, which is difficult to eliminate airborne germs. In addition, it is difficult for existing air purifiers to quickly and effectively disinfect the internal space of the equipment, and it is often necessary to disassemble the equipment for manual disinfection and cleaning. Manual disinfection and cleaning, on the one hand, increases the user's operating burden, and on the other hand, easily exposes the operator to the invasion of germs. Summary of the invention

[0004] The purpose of the present invention is to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides an air purifier that can filter pollutants in the air and disinfect the air to improve the purification effect.

[0006] The air purifier according to the embodiment of the present invention has at least the following beneficial effects: a large amount of dust and harmful substances will be generated during the process of manicure and pedicure, and these dust and harmful substances will remain in the device after being purified by the air purifier. The internal space of the device is automatically disinfected and sterilized by the disinfection mechanism after the air purification work is completed, which can replace the user to disassemble the device for manual disinfection. On the one hand, it reduces the user's operating burden, and on the other hand, it avoids the user from contacting with harmful substances, thereby ensuring the user's safety. The disinfection mechanism and the fan can operate at the same time. At this time, the fan operates to suck air into the device from the air inlet, and the disinfection mechanism irradiates and disinfects the air sucked into the device, and the air is then filtered through the filter and discharged from the air outlet.

[0048] refer to Figures 1 to 6 An air purifier according to an embodiment of the present invention is described.

[0049] like Figures 1 to 6 As shown, the air purifier according to the embodiment of the present invention includes: a shell 100, an air inlet 110 is opened at the lower end of the shell 100, an air inlet grid 210 is arranged on the air inlet 110, an air outlet 120 is opened at the upper end of the shell 100, and an air outlet grid 310 is arranged on the air outlet 120; a fan 400, the fan 400 is arranged in the shell 100; a lighting mechanism 500, the lighting mechanism 500 is arranged at the lower end of the shell 100; a filter 600, the filter 600 is arranged in the shell 100; a disinfection mechanism 700, the disinfection mechanism 700 is arranged in the shell 100, and the disinfection mechanism 700 is used to disinfect the air inside the shell 100.

[0050] The disinfection mechanism 700 includes an ultraviolet generator 710. A first scattering member 720 is provided on the upper cover of the ultraviolet generator 710. The first scattering member 720 is a transparent member. The ultraviolet generator 710 is in a ring shape, and a plurality of ultraviolet light emitting diodes 730 are evenly distributed on the ultraviolet generator 710.

[0051] The air purifier further includes an air inlet cover plate 200, which is detachably mounted on the air inlet 110, and an air inlet grid 210 is disposed on the air inlet cover plate 200. A trigger switch 111 is disposed on the air inlet 110, and a trigger member 220 is disposed on the air inlet cover plate 200. When the air inlet cover plate 200 is removed from the air inlet 110, the trigger member 220 is separated from the trigger switch 111, and the fan 400 stops operating. A first vibration-damping gasket 230 is disposed between the air inlet grid 210 and the air inlet cover plate 200. The air inlet grid 210 is formed by splicing a plurality of hexagonal elongated air ducts 211.

[0052] The lighting mechanism 500 includes an annular light strip 510, which is arranged downward at the lower end of the housing 100. A second scattering member 520 is provided at the lower end of the annular light strip 510, and the second scattering member 520 is a transparent member. The outer side of the lighting mechanism 500 is surrounded by a light collecting portion 130 formed by the housing 100 protruding downward.

[0053] A bracket 140 is provided in the housing 100, a fan 400 is provided at the lower end of the bracket 140, and a filter 600 is provided at the upper end of the bracket 140. The fan 400 is connected to the bracket 140 through a second vibration-damping washer 410. The filter 600 is in a circular column shape, and the filter 600 is a HEPA filter. An inertial dust collecting tank 150 is also provided in the housing 100, and the inertial dust collecting tank 150 is located outside the upper end of the filter 600. The inertial dust collecting tank 150 is located above the disinfection mechanism 700.

[0054] The air purifier also includes a power supply assembly 800, which is arranged at the upper end of the bracket 140, the power supply assembly 800 is located inside the filter 600, and the power supply assembly 800 is electrically connected to the lighting mechanism 500 and the disinfection mechanism 700 respectively. It also includes a deflector 810, which is arranged on the power supply assembly 800. The cross-sectional area of ​​the deflector 810 gradually increases from top to bottom. The external power supply is electrically connected to the power supply assembly 800 and the fan 400 respectively, that is, the 220V external power supply directly supplies power to the fan 400, and the 220V external power supply is converted by the power supply assembly 800 and then supplies power to the disinfection mechanism 700 and the lighting mechanism 500.

[0055] In some specific embodiments of the present invention, when the disinfection mechanism 700 is operating, the fan 400 and the lighting mechanism 500 automatically stop operating, and the power supply assembly 800 supplies power to the disinfection mechanism 700; when the fan 400 and the lighting mechanism 500 are operating, the disinfection mechanism 700 automatically stops operating, and the power supply assembly 800 supplies power to the lighting mechanism 500.

[0056] In some other specific embodiments of the present invention, the disinfection mechanism 700 , the fan 400 and the lighting mechanism 500 operate simultaneously, and the power supply assembly 800 supplies power to the disinfection mechanism 700 and the lighting mechanism 500 simultaneously.

[0057] like Figures 1 to 6As shown, the shell 100 is roughly cylindrical, the air inlet 110 is arranged at the lower end of the shell 100 along the axis of the shell 100, the air outlet 120 is arranged at the upper end of the shell 100 along the axis of the shell 100, the fan 400 is arranged on the side of the shell 100 close to the air inlet 110, the filter 600 is arranged on the side of the shell 100 close to the air outlet 120, and the fan 400 and the filter 600 are both arranged along the axis of the shell 100. The operation of the fan 400 draws air in the manicure and pedicure working environment from the air inlet 110 into the shell 100. After entering the shell 100, the air flows in a direction away from the axis of the shell 100 under the action of the fan 400, so that the air flows to the outside of the fan 400 and flows upward along the inner wall of the shell 100. After the air flows upward to the outside of the filter 600, it passes through the filter 600 from the outside to the inside. The filter 600 purifies the air, and the purified air flows out from the air outlet 120 at the upper end of the shell 100.

[0058] like Figures 2 to 6 As shown, the disinfection mechanism 700 is arranged in the housing 100, and the disinfection mechanism 700 includes an ultraviolet generator 710, which is annular and arranged on the bottom surface inside the housing 100, and a plurality of ultraviolet light emitting diodes 730 are evenly distributed along the circumferential direction on the upper end surface of the ultraviolet generator 710, and a first scattering member 720 is irradiated on the ultraviolet generator 710. Therefore, the ultraviolet light emitted by the ultraviolet light emitting diode 730 passes through the transparent first scattering member 720 and shines on the area where the air flows through the housing 100, thereby killing the germs in the air in the housing 100. The transparent first scattering member 720 protects the ultraviolet light emitting diode 730 on the one hand, and does not block the ultraviolet light emitted by the ultraviolet light emitting diode 730 on the other hand.

[0059] In the above technical solution, the disinfection mechanism 700 can use other common disinfection methods, such as heat disinfection, other radiation disinfection, etc., in addition to using ultraviolet irradiation for disinfection and sterilization. In addition, the setting position and shape of the ultraviolet generator 710 can also be adjusted according to the arrangement of the air duct inside the housing 100.

[0060] In some specific embodiments of the present invention, the operation of the disinfection mechanism 700 is interlocked with the operation of the fan 400, that is, when the user switches the air purifier to the air purification mode, the fan 400 operates and the disinfection mechanism 700 automatically stops operating, and the fan 400 draws air from the environment into the device and purifies it through the filter 600. After the air purification mode is completed, the user switches the air purifier to the disinfection mode, the disinfection mechanism 700 operates and the fan 400 stops operating, and the disinfection mechanism 700 kills the germs remaining in the device through ultraviolet light irradiation.

[0061] In the above technical solution, the power supply assembly 800 is a power adapter connected to an external power supply. The power supply assembly 800 does not need to supply power to the lighting mechanism 500 and the disinfection mechanism 700 at the same time. When entering the air purification mode, the external power supply directly supplies power to the fan 400. The fan 400 has a strong wind pressure under the power supply of the 220V external power supply, and the power supply assembly 800 supplies power to the lighting mechanism 500 alone; when entering the disinfection mode, the power supply assembly 800 supplies power to the disinfection mechanism 700 alone. Thereby reducing the cost of the power supply assembly 800. The direct connection of the 220V external power supply improves the power and purification effect of the fan 400.

[0062] A large amount of dust and harmful substances will be generated during the process of manicure and pedicure. These dust and harmful substances will remain in the equipment after being purified by the air purifier. The disinfection mechanism 700 will automatically disinfect and sterilize the internal space of the equipment after the air purification work is completed, which can replace the user's disassembly of the equipment for manual disinfection. On the one hand, it reduces the user's operating burden, and on the other hand, it avoids the user from contacting with harmful substances, thereby ensuring the user's safety.

[0063] In some other specific embodiments of the present invention, the disinfection mechanism 700, the lighting mechanism 500 and the fan 400 can operate simultaneously, the external power supply directly supplies power to the fan 400, and the power supply assembly 800 supplies power to the disinfection mechanism 700 and the lighting mechanism 500 at the same time. At this time, the fan 400 operates to suck air into the device from the air inlet 110, and the disinfection mechanism 700 irradiates and disinfects the air sucked into the device, and the air is then filtered by the filter 600 and discharged from the air outlet 120. Thus, through the dual effects of the disinfection mechanism 700 and the filter, the purification effect of the air purifier is further improved.

[0064] like Figures 1 to 6 As shown, a bracket 140 is disposed inside the housing 100 , a fan 400 is disposed at the lower end of the bracket 140 , the fan 400 is connected to the bracket 140 via a second vibration-damping washer 410 , and a power supply assembly 800 and a filter 600 are disposed at the upper end of the bracket 140 .

[0065] Currently, the air purification equipment used in nail rooms usually sets the power adapter on the outside of the air purification equipment to reduce the impact of heat and vibration of the power adapter on the air purification equipment. However, doing so will cause the fan to be powered by the power adapter, and the power supply voltage of the power adapter is low, which will cause problems such as low wind pressure generated by fan 400.

[0066] The air purifier sets the power assembly 800 as a whole inside the housing 100. After the external power supply is connected to the power assembly 800, the power assembly 800 supplies power to the lighting mechanism 500 and the disinfection mechanism 700. At the same time, the external power supply is directly electrically connected to the fan 400, so that the fan can be driven by a higher voltage and has a stronger power. In addition, a deflector 810 is set on the power assembly 800. The deflector 810 is roughly conical with a narrow top and a wide bottom. The deflector 810 has a drainage effect on the air in the housing 100, and the air after passing through the filter 600 is drained toward the air outlet 120, thereby reducing the vibration and noise of the air purifier as a whole. On the other hand, the deflector 810 protects the power assembly 800, prevents foreign matter from damaging the power assembly 800, and also prevents the user from touching the power assembly 800 when disassembling the device to replace the filter 600, thereby ensuring the safety of the user. The power supply assembly 800 in the air duct 810 dissipates heat through the heat dissipation holes 820. The hot air in the air duct 810 rises along the inner wall of the air duct 810. At this time, the airflow driven by the fan 400 passes through the filter 600 and then goes along the outer wall of the air duct 810. Therefore, the airflow driven by the fan 400 will take away part of the heat of the hot air in the air duct 810, thereby accelerating the heat dissipation of the power supply.

[0067] Therefore, after the power supply assembly 800 is built in, the fan 400 obtains stronger power due to direct connection with the external power supply, thereby providing a stronger air duct to bring better purification effect and higher purification efficiency. The vibration and heating problems caused by the power supply assembly 800 being built in the housing 100 are solved by setting a second vibration-damping gasket 410 between the fan 400 and the bracket 140 to reduce the impact of vibration caused by stronger wind pressure; by setting the deflector 810, the air flow during the operation of the air purifier is utilized to promote the heat dissipation of the power supply assembly 800, and the deflector 810 also protects the user and the power supply assembly 800.

[0068] like Figures 1 to 6 As shown, the inertial dust collecting groove 150 is annular and is arranged on the inner wall at the top of the housing 100. The filter 600 is in the shape of a circular ring, and the inertial dust collecting groove 150 is wound around the outer side of the upper end of the filter 600. After the fan 400 sucks air into the housing 100 from the air inlet 110, the air is blown outward along the fan 400 and then flows upward along the inner wall of the housing 100 in a spiral. When the air flows upward to the inertial dust collecting groove 150, the larger harmful particles in the air collide into the inertial dust collecting groove 150 under the action of inertia, so that the larger harmful particles are stored in the inertial dust collecting groove 150. After the larger harmful particles are deposited, the air passes through the filter 600 from the outside to the inside, so that the smaller harmful particles are filtered by the filter 600.

[0069] Therefore, large particles of harmful substances in the air are deposited in advance before filtering by the filter 600, preventing the large particles of harmful substances from directly blowing toward the filter 600 and causing blockage or damage to the filter 600, thereby improving the filtering effect of the filter 600 and extending the service life of the filter 600.

[0070] The disinfection mechanism 700 is located below the inertial dust collecting tank 150, which is convenient for disinfecting and sterilizing the accumulated harmful substances. In addition, if the user needs to manually clean the inside of the air purifier, he only needs to disassemble the shell 100 and clean the inertial dust collecting tank 150, which is simple and convenient to operate.

[0071] like Figures 2 to 6 As shown, an air inlet cover 200 is provided on the air inlet 110, and the air inlet cover 200 is detachably mounted on the air inlet 110, and an air inlet grid 210 is provided on the air inlet cover 200. A trigger switch 111 is provided on the air inlet 110, and a trigger member 220 is provided on the air inlet cover 200. When the air inlet cover 200 is removed from the air inlet 110, the trigger member 220 is separated from the trigger switch 111, and the fan 400 stops operating. Thus, the user can clean or repair the interior of the air purifier by removing the air inlet cover 200. When the user removes the air inlet cover 200, the separation of the trigger member 220 and the trigger switch 111 will cause the fan 400 to work, thereby preventing the fan 400 from rotating and injuring the user. The air inlet cover 200 can be installed on the air inlet 110 by common detachable installation methods such as magnetic attraction, which is convenient for the user to disassemble and assemble. The trigger member 220 is a magnet, and the trigger switch 111 is a magnetic induction switch. It is conceivable that the trigger member 220 and the trigger switch 111 can also be other common switch forms. A first vibration-damping washer 230 is provided between the air inlet grid 210 and the air inlet cover plate 200. The first vibration-damping washer 230 is provided to reduce the influence of the vibration of the air inlet grid 210 on the overall device when air flows through the air inlet grid 210.

[0072] like Figure 6 As shown, the air inlet grid 210 is formed by splicing a plurality of hexagonal elongated air ducts 211. That is, the air inlet grid 210 is a mesh structure of aluminum honeycomb, and the aluminum honeycomb structure makes the air inlet grid 210 both light and strong. The air inlet grid 210 is composed of a plurality of elongated air ducts 211 arranged in the up and down directions, which can straighten the airflow passing through the air inlet grid 210, eliminate the influence of turbulence, and increase the density of the airflow. The setting of the air inlet grid 210 can prevent foreign matter from entering the housing 100 and causing harm to the fan 400 and the user. The air inlet grid 210 and the fan 400 are directly provided with a guide plate 160, which guides the air entering from the air inlet grid 210 to flow to the fan 400.

[0073] like Figures 2 to 6As shown, the lighting mechanism 500 includes an annular light strip 510, which is arranged downward at the lower end of the housing 100. The lower end of the annular light strip 510 is covered with a second scattering member 520, which is a transparent member. The outer side of the lighting mechanism 500 is surrounded by a light focusing portion 130 formed by the housing 100 protruding downward. The light focusing portion 130 can make the light emitted by the lighting mechanism 500 face the direction set by the user, so as to avoid the user looking directly at the light source when using the air purifier and reduce the user's eye fatigue.

[0074] In summary, the air purifier improves the air purification effect, reduces the vibration and noise during the operation of the equipment, and at the same time improves the convenience of using, maintaining and cleaning the equipment.

[0075] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
