Description

air purifier Technical Field

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

[0002] Manicurists' work environments are subject to harmful and hazardous factors, such as dust, volatile hazardous substances and chemicals in the air of the work area, and visual fatigue caused by insufficient lighting in the workplace. Furthermore, manicurists' workplaces are small and often located in the hallways of large shopping malls, stores, and office buildings, making it difficult to provide air ventilation using the building's ventilation systems. To reduce the impact of harmful factors, they must be eliminated in whole or in part. These issues can be addressed through the use of personal respiratory protective equipment and the placement of additional lighting in the workplace. However, the use of personal respiratory protective equipment at work can be inconvenient and cannot guarantee the protection of the manicurist's clients.

[0003] During the manicure process, such as polishing and removing the cuticle, a large amount of dust and chemical fumes are generated. The drying process also produces harmful aerosols and particles. Air purifiers can purify the air in manicure and pedicure environments. Current air purifiers used in manicure and pedicure environments typically only filter the air through a filter, making it difficult to eliminate airborne pathogens. Furthermore, existing air purifiers struggle to quickly and effectively disinfect the interior of the device, often requiring the device to be disassembled for manual disinfection and cleaning. This manual disinfection and cleaning process not only increases the user's workload but also exposes the operator to pathogens. Summary of the Invention

[0040] An air purifier according to an embodiment of the present application is described with reference to FIG. 1 to FIG. 6 .

[0041] As shown in Figures 1 to 6, the air purifier according to an embodiment of the present application includes: a shell 100, an air inlet 110 is opened at the lower end of the shell 100, an air inlet grid 210 is provided on the air inlet 110, an air outlet 120 is opened at the upper end of the shell 100, an air outlet grid 310 is provided 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.

[0042] The disinfection mechanism 700 includes an ultraviolet generator 710. The ultraviolet generator 710 is covered with a first scattering member 720. The first scattering member 720 is a transparent member. The ultraviolet generator 710 is annular and has a plurality of ultraviolet light-emitting diodes 730 evenly distributed on the ultraviolet generator 710.

[0043] The air purifier also includes an air inlet cover plate 200, which is removably mounted on the air inlet 110. 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 separates from the trigger switch 111, and the fan 400 stops operating. A first vibration-damping washer 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 together a plurality of hexagonal, elongated air ducts 211.

[0044] The lighting mechanism 500 includes an annular light strip 510, which is disposed downwardly 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. The second scattering member 520 is transparent. The outer side of the lighting mechanism 500 is surrounded by a light collecting portion 130 formed by a downward protrusion of the housing 100.

[0045] A bracket 140 is provided within the housing 100. The fan 400 is mounted at the lower end of the bracket 140, and the filter 600 is mounted at the upper end of the bracket 140. The fan 400 is connected to the bracket 140 via a second vibration-damping washer 410. The filter 600 is an annular cylindrical filter and is a HEPA filter. An inertial dust collection trough 150 is also provided within the housing 100. The inertial dust collection trough 150 is located outside the upper end of the filter 600. The inertial dust collection trough 150 is located above the disinfection mechanism 700.

[0046] 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.

[0047] In some specific embodiments of the present application, 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.

[0048] In some other specific embodiments of the present application, 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.

[0049] As shown in Figures 1 to 6, 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, and 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, and the filter 600 is arranged on the side of the shell 100 close to the air outlet 120. 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 from the manicure and pedicure working environment into the shell 100 from the air inlet 110. After the air enters the shell 100, it 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.

[0050] As shown in Figures 2 to 6, the disinfection mechanism 700 is disposed within the housing 100 and includes a UV generator 710. The UV generator 710 is annular and disposed on the bottom surface of the housing 100. Multiple UV LEDs 730 are evenly distributed along the circumference of the upper end surface of the UV generator 710. A first scattering member 720 is provided on the UV generator 710. Thus, the UV light emitted by the UV LEDs 730 passes through the transparent first scattering member 720 and shines onto the area within the housing 100 where air flows, thereby killing pathogens in the air within the housing 100. The transparent first scattering member 720 protects the UV LEDs 730 while not blocking the UV light emitted by the UV LEDs 730.

[0051] 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 location and shape of the ultraviolet generator 710 can also be adjusted according to the layout of the air duct inside the housing 100.

[0052] In some embodiments of the present application, 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 air purification mode, the fan 400 operates and the disinfection mechanism 700 automatically stops operating. The fan 400 draws air from the environment into the device and filters and purifies it through the filter 600. After the air purification mode is completed, the user switches the air purifier to disinfection mode. The disinfection mechanism 700 operates and the fan 400 stops operating. The disinfection mechanism 700 kills germs remaining in the device through ultraviolet light irradiation.

[0053] In the above technical solution, the power supply assembly 800 is a power adapter connected to an external power source. The power supply assembly 800 does not need to simultaneously supply power to the lighting mechanism 500 and the disinfection mechanism 700. When the air purification mode is entered, the external power source directly supplies power to the fan 400. When powered by a 220V external power source, the fan 400 has a strong wind pressure, while the power supply assembly 800 alone supplies power to the lighting mechanism 500. When the disinfection mode is entered, the power supply assembly 800 alone supplies power to the disinfection mechanism 700. This reduces the cost of the power supply assembly 800. Direct connection to a 220V external power source increases the power of the fan 400 and the purification effect.

[0054] During the manicure and pedicure process, a large amount of dust and harmful substances will be generated. These dust and harmful substances will remain in the device after being purified by the air purifier. The disinfection mechanism 700 will automatically disinfect and sterilize the internal space of the device after the air purification work is completed, which can replace the user's disassembly of 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.

[0055] In some other specific embodiments of the present application, the disinfection mechanism 700, the lighting mechanism 500, and the fan 400 can operate simultaneously, with an external power supply directly supplying power to the fan 400, and the power supply assembly 800 simultaneously supplying power to the disinfection mechanism 700 and the lighting mechanism 500. In this case, the fan 400 operates to draw air into the device through the air inlet 110, and the disinfection mechanism 700 irradiates and disinfects the air drawn into the device. The air is then filtered through the filter 600 and discharged from the air outlet 120. Thus, through the dual functions of the disinfection mechanism 700 and the filter, the purification effect of the air purifier is further improved.

[0056] As shown in Figures 1 to 6, a bracket 140 is provided inside the shell 100, a fan 400 is provided at the lower end of the bracket 140, the fan 400 is connected to the bracket 140 through a second vibration-damping washer 410, and the power supply assembly 800 and the filter 600 are provided at the upper end of the bracket 140.

[0057] Currently, air purification equipment used in nail salons usually places 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 lead to problems such as low wind pressure generated by fan 400.

[0058] This air purifier sets the power supply assembly 800 as a whole inside the housing 100. After the external power supply is connected to the power supply assembly 800, the power supply assembly 800 then 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 supply assembly 800. The deflector 810 is roughly conical in shape, narrow at the top and wide at the 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 has a protective effect on the power supply assembly 800, preventing foreign matter from damaging the power supply assembly 800, and also preventing the user from touching the power supply 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 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.

[0059] Therefore, after the power supply assembly 800 is built in, the fan 400 obtains stronger power due to its direct connection to the external power supply, thereby providing a stronger air duct for better purification effect and higher purification efficiency. The vibration and heat problems caused by the power supply assembly 800 being built into the housing 100 are solved by providing a second vibration-damping washer 410 between the fan 400 and the bracket 140, reducing the impact of the vibration caused by the stronger wind pressure. By providing 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. At the same time, the deflector 810 also protects the user and the power supply assembly 800.

[0060] As shown in Figures 1 to 6, the inertial dust collecting groove 150 is annular and is arranged on the inner wall of the top of the housing 100. The filter 600 is in the shape of a circular column, 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 draws air into the housing 100 from the air inlet 110, the air is blown outward along the fan 400 and flows upward in a spiral along the inner wall of the housing 100. When the air flows upward to the inertial dust collecting groove 150, the larger harmful particles in the air collide with the inertial dust collecting groove 150 under the action of inertia, causing the larger harmful particles to accumulate 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, causing the smaller harmful particles to be filtered by the filter 600.

[0061] 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 blowing directly towards 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.

[0062] The disinfection mechanism 700 is located below the inertial dust collection tank 150, which facilitates the disinfection and sterilization of accumulated harmful substances. In addition, if the user needs to manually clean the interior of the air purifier, they only need to disassemble the housing 100 and clean the inertial dust collection tank 150, which is simple and convenient.

[0063] As shown in Figures 2 to 6, an air inlet cover 200 is provided on the air inlet 110. 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 separates 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 operate, 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 contemplated that the trigger member 220 and the trigger switch 111 may also be other common switch forms. A first vibration-damping washer 230 is disposed between the air inlet grid 210 and the air inlet cover 200. The first vibration-damping washer 230 reduces the impact of vibrations from the air inlet grid 210 on the overall device when air flows through it.

[0064] As shown in Figure 6, the air inlet grid 210 is formed by splicing together a plurality of hexagonal elongated air ducts 211. That is, the air inlet grid 210 is a mesh structure of aluminum honeycomb. 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.

[0065] As shown in Figures 2 to 6, the lighting mechanism 500 includes an annular light strip 510, which is positioned downwardly at the lower end of the housing 100. A second, transparent scattering member 520 covers the lower end of the annular light strip 510. A light focusing portion 130, formed by a downward protrusion from the housing 100, surrounds the outer surface of the lighting mechanism 500. This light focusing portion 130 directs the light emitted by the lighting mechanism 500 in the direction set by the user, preventing the user from looking directly at the light source while using the air purifier and reducing eye fatigue.

[0066] In summary, the air purifier improves the air purification effect, reduces the vibration and noise during the operation of the equipment, and improves the convenience of use, maintenance and cleaning of the equipment.

[0067] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present application.
