Description
Technical Field
[0001] This utility model relates to the field of air purification equipment technology, and in particular to a multifunctional air purifier. Background Technology
[0002] Air purifiers, as household or commercial appliances designed to improve indoor air quality, are widely used to remove pollutants such as particulate matter, formaldehyde, and odors from the air. Their core working principle typically involves a fan driving air through a series of filters, purifying the air through physical filtration and adsorption. However, with increasing public awareness of health, particularly concerns about microbial contamination such as bacteria and viruses, simple physical filtration is no longer sufficient. Therefore, air purifiers integrating disinfection and sterilization functions have emerged on the market.
[0003] However, in existing air purifiers that combine disinfection functions, the ultraviolet lamp is often placed outside the filter or at the air outlet. This arrangement may result in some air being discharged without being fully disinfected, leaving room for improvement in sterilization efficiency. At the same time, the powerful ultraviolet light source may also pose a safety hazard if it is accidentally leaked. Utility Model Content
[0004] The purpose of this invention is to provide a multifunctional air purifier with a more reasonable structure, more thorough disinfection, and greater safety and reliability.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a multifunctional air purifier, comprising a purifier body, the purifier body comprising a top plate, a base, and a purification component located between the top plate and the base, the purification component comprising a filter element and an exhaust component abutting above the filter element, a support plate abutting the filter element being disposed above the base, the exhaust component, the support plate, and the filter element together forming a disinfection space, a disinfection component being disposed on the support plate opposite to the exhaust component, the disinfection component being used to disinfect the air circulating in the disinfection space.
[0006] By adopting the above technical solution, since the exhaust component is abutted above the filter element and the support plate is abutted below the filter element, the disinfection space is formed into a relatively sealed space. External air only enters through the filter element, and the disinfection component located in the disinfection space can fully disinfect the air entering the disinfection space, effectively improving the sterilization efficiency. At the same time, the relatively sealed disinfection space prevents the leakage of ultraviolet light source and eliminates safety hazards.
[0007] A further feature of this invention is that the disinfection assembly includes an ultraviolet lamp plate fixedly disposed below the support plate, the ultraviolet lamp plate is provided with a plurality of UV lamps, and the support plate is provided with a plurality of light-transmitting holes spaced apart for the UV lamps to pass through.
[0008] By adopting the above technical solution, the ultraviolet lamp's irradiation angle covers the entire disinfection space, making disinfection more thorough.
[0009] A further feature of this invention is that a heating component is provided inside the top plate, and the heating component forms a heating surface at the upper end of the top plate.
[0010] By adopting the above technical solution, items placed on the top plate can be heated, providing versatility in functionality.
[0011] A further feature of this invention is that the top plate is formed by an upper cover plate and a lower cover plate, and the heating assembly includes a heating plate located between the upper cover plate and the lower cover plate.
[0012] By adopting the above technical solution, the heating plate transfers the heat generated by electric heating to the upper cover plate, thereby heating the items on the upper cover plate. The more user-friendly design makes life more convenient.
[0013] A further feature of this invention is that a support frame is provided below the support plate, and an elastic element is provided between the support frame and the support plate. The elastic element drives the support plate to float in the vertical direction. The support plate has a hollow mounting portion extending toward the support frame, and a limiting element is provided on the hollow mounting portion. The limiting element and the support frame together constrain the displacement path of the support plate in the vertical direction.
[0014] By adopting the above technical solution, the support plate is firmly pressed against the filter element and the bottom of the filter element is covered, so that outside air can only enter the disinfection channel through the filter element, ensuring the air filtration effect and preventing the ultraviolet light source from leaking from the bottom of the filter element. This not only improves the disinfection efficiency but also eliminates safety hazards.
[0015] A further feature of this invention is that the outer surface of the purification component is covered with an integrated grille structure, the grille structure is located between the top plate and the base, and the grille structure has an air inlet area and an air outlet area spaced apart along the vertical direction.
[0016] By adopting the above technical solution, the grille structure is applied to both the air intake and exhaust areas of the grille structure. This avoids the need for two separate grille structures for air intake and exhaust, saving production costs, optimizing equipment space utilization, and making the overall appearance symmetrical and aesthetically pleasing.
[0017] A further feature of this invention is that the top plate and the base are spaced apart from the grid structure, forming annular grooves distributed vertically.
[0018] A further feature of this invention is that each of the annular grooves is provided with a cat-teasing ball, and the cat-teasing ball has a displacement path for circumferential movement within the annular groove.
[0019] By adopting the above technical solution and setting up a cat-teasing ball for cats to play with, the functionality becomes more diverse and more user-friendly.
[0020] A further feature of this invention is that an exhaust mesh cover is fixedly installed on the top of the grille structure, the exhaust mesh cover forming the bottom wall of the annular groove located above, and both the top plate and the exhaust mesh cover are provided with arc-shaped recesses, so that the cat-teasing ball can move within the arc-shaped recesses of the top plate and the exhaust mesh cover.
[0021] By adopting the above technical solution, the air purified by the filter element can be discharged from both the side grille structure and the top exhaust hood, increasing the exhaust area and improving the exhaust efficiency.
[0022] A further feature of this invention is that the exhaust assembly includes a motor, the exhaust screen has a downward recessed center forming an installation cavity, a screen bracket fixedly connected to the wall of the installation cavity is mounted inside the grille structure, and the motor is placed inside the installation cavity and fixedly connected to the screen bracket.
[0023] By adopting the above technical solution, the motor is fixed in an independent chamber, which facilitates maintenance and replacement.
[0024] In summary, this utility model has the following beneficial effects:
[0025] 1. An exhaust fan is positioned above the filter element, and a support plate is positioned below the filter element, creating a relatively enclosed disinfection space. External air enters only through the filter element, and the disinfection components within the disinfection space thoroughly disinfect the air entering the space, effectively improving sterilization efficiency. At the same time, the relatively enclosed disinfection space prevents leakage of ultraviolet light sources, eliminating potential safety hazards.
[0026] 2. The top plate is equipped with a heating component. The heating component uses electric heating to create a heating surface on the top plate, which heats the items placed on the top plate, thus providing multiple functions.
[0027] 3. A cat-teasing ball is placed inside a ring groove, allowing the ball to move circumferentially within the groove, making it more versatile and user-friendly.
[0028] 4. The grid structure includes at least two sets of grid plates facing different directions. It draws in outside air from different areas through the air inlet area into the filter element, and then discharges the filtered air through the inside of the filter element to the air outlet area. Since the grid plate group in the air outlet area and the grid plate group in the air inlet area are integrated, the filtered air can also be discharged to different areas. Using a single independent grid structure can achieve multi-angle air intake and exhaust, which not only eliminates purification dead corners and improves purification efficiency, but also avoids setting up two sets of grid structures for air intake and exhaust, saving production costs and optimizing equipment space utilization.

[0035] The present invention will be further described below with reference to the accompanying drawings.
[0036] A multi-functional air purifier, such as Figure 1-5As shown, the device includes a main body of the purifier, which includes a top plate 11, a base 12, and a purification assembly located between the top plate 11 and the base 12. The purification assembly includes a filter element 13 and an exhaust assembly that abuts against the filter element 13. A support plate 2 that abuts against the filter element 13 is provided above the base 12. The exhaust assembly, the support plate 2, and the filter element 13 together form a disinfection space 18. A disinfection assembly that is positioned opposite to the exhaust assembly is provided on the support plate 2. The disinfection assembly is used to disinfect the air circulating in the disinfection space 18. The filter element 13 is a hollow ring. The filter element 13 and the exhaust assembly are preferably arranged vertically, with an air inlet grille 16 positioned between them. The air inlet grille 16 seals over the filter element 13. A protective cover 17 is provided around the exhaust assembly. The protective cover 17 is hollow, with its bottom resting on the air inlet grille 16 and completely covering the air inlet holes on the grille 16. Its top is fixedly connected to the mesh cover bracket 6. Outside air passes through the filter element 13 and flows vertically upwards under the action of the exhaust assembly, passing through the air inlet holes on the air inlet grille 16 and entering the space between the exhaust assembly and the protective cover 17. The gap space is then passed through the mesh support 6 above the protective cover 17, thus forming a disinfection channel. Since the disinfection channel is relatively straight, and the exhaust component abuts against the top of the filter element 13 and the support plate 2 abuts against the bottom of the filter element 13, the disinfection space 18 forms a relatively sealed space, and the outside air only enters through the filter element 13. The disinfection component located directly below the disinfection channel can completely cover the disinfection channel without creating dead corners, making the disinfection effect more thorough and effectively improving the sterilization efficiency. At the same time, the relatively sealed disinfection space 18 prevents the leakage of ultraviolet light source and eliminates safety hazards.
[0037] Preferably, the disinfection assembly includes an ultraviolet lamp plate 21 fixedly disposed below the support plate 2. The ultraviolet lamp plate 21 is provided with a plurality of UV lamps 211, and the support plate 2 has a plurality of light-transmitting holes 22 spaced apart to allow the UV lamps 211 to pass through. The light-transmitting holes 22 are located at the center of the support plate 2 and correspond to the central axis of the filter element 13. Ultraviolet light passes through the light-transmitting holes 22 and vertically through the disinfection channel. The irradiation angle of the UV lamps 211 covers the entire disinfection channel, resulting in thorough disinfection.
[0038] Preferably, a heating component is provided inside the top plate 11, which forms a heating surface at the upper end of the top plate 11. The top plate 11 is a heat-conducting plate, and the heating component forms a heating surface on the top plate 11 through electric heating, so as to heat items placed on the top plate 11, such as water cups, towels, tableware, etc., and has multiple functions.
[0039] Preferably, the top plate 11 is formed by an upper cover plate 111 and a lower cover plate 112. The heating assembly includes a heating plate 113, which is located between the upper cover plate 111 and the lower cover plate 112. The lower cover plate 112 supports and fixes the heating plate 113. The lower cover plate 112 is made of thermally insulating material, while the upper cover plate 111 is made of thermally conductive material. The heating plate 113 transfers the heat from electrical heating to the upper cover plate 111, thereby heating the items on the upper cover plate 111. This more user-friendly design makes life more convenient.
[0040] Preferably, a support frame 31 is provided below the support plate 2, and an elastic element 32 is provided between the support frame 31 and the support plate 2. The elastic element 32 drives the support plate 2 to float vertically. The support plate 2 has a hollow mounting part 23 extending toward the support frame 31, and a limiting element 24 is provided on the hollow mounting part 23. The limiting element 24 and the support frame 31 together constrain the vertical displacement path of the support plate 2. The support frame 31 is integrally formed with an air inlet mesh cover 7. When the filter element 13 is placed into the main body of the purifier, it presses the support plate 2 to move toward the base 12. Since the air inlet mesh cover 7 is fixedly connected between the grille and the base 12, during the movement of the support plate 2, the support frame 31 will gradually press the elastic element 32 to deform it. Under the elastic force of the elastic element 32, the support plate 2 will firmly press against the filter element 13 and cover the bottom of the filter element 13, so that outside air can only enter the disinfection channel through the filter element 13, ensuring the air filtration effect. To prevent ultraviolet light from leaking from the bottom of the filter element 13, the disinfection efficiency is improved and the safety hazards are eliminated. The limiting member 24 on the hollow mounting part 23 is a bolt. The bolt is tightened into the hollow mounting part 23. Since the diameter of the bolt is larger than the maximum hole diameter of the support frame 31, when the filter element 13 is removed and the support plate 2 moves upward under the force of the elastic member 32, the bolt can abut against the support frame 31 to form a limit, preventing the hollow mounting part 23 from falling out of the support frame 31, making the support plate 2 more stable and ensuring the floating effect of the support plate 2.
[0041] Preferably, the outer surface of the purification component is covered with an integrated grille structure 4, which is located between the top plate 11 and the base 12. The grille structure 4 has an air inlet area 41 and an air outlet area 42 arranged vertically at intervals. The grille structure 4 is arranged in a ring around the top plate 11 and the base 12, forming a structural design in which the grille structure 4 is used in both the air intake area and the air exhaust area of the grille structure 4. This avoids the need for two sets of grille structures 4 for air intake and exhaust, saving production costs, optimizing equipment space utilization, and making the overall appearance symmetrical and aesthetically pleasing.
[0042] Preferably, the top plate 11 and the base 12 are respectively spaced apart from the grid structure 4, forming annular grooves 15 distributed vertically.
[0043] In a preferred embodiment, an air inlet screen 7 is provided below the support plate 2. The base 12 and the grille structure 4 are spaced apart, and the air inlet screen 7 is located in the spaced space. The air inlet screen 7 is arc-shaped and tilted towards the central axis of the filter element 13. The top of the arc is fixedly connected to the grille structure 4, and the bottom of the arc is fixedly connected to the base 12. This allows the purifier to draw air in from both the side grille structure 4 and the air inlet screen 7. Because the air inlet screen 7 is arc-shaped, the natural air entering from the end of the air inlet screen 7 will be drawn into the top of the air inlet screen 7 in a streamlined manner, reducing the spillage of natural air. Then, it will converge with the natural air entering from the side grille structure 4 and pass through the filter element 13 together, thereby increasing the air intake area and improving the air intake efficiency.
[0044] Preferably, each of the annular grooves 15 is provided with a cat-teasing ball 151, and the cat-teasing ball 151 has a displacement path for circumferential movement within the annular groove 15. Cat-teasing balls 151 are provided at both the top and bottom of the purifier for cats to play with, making the function more versatile and more user-friendly.
[0045] Preferably, an exhaust screen 5 is fixedly installed on the top of the grille structure 4. The exhaust screen 5 forms the bottom wall of the annular groove 15 located above. Both the top plate 11 and the exhaust screen 5 are provided with arc-shaped recesses 51, allowing the cat toy ball 151 to move within the arc-shaped recesses 51 of the top plate 11 and the exhaust screen 5. The exhaust screen 5 is fixedly connected to the top plate 11. By spacing the top plate 11 and the grille structure 4, the air purified by the filter element 13 can be discharged from both the side grille structure 4 and the top exhaust screen 5, increasing the exhaust area and improving the exhaust efficiency.
[0046] In a preferred embodiment, the exhaust screen 5 is wavy, with the arc-shaped recess 51 of the exhaust screen 5 forming the troughs of the wave. The wavy surface disperses the exhaust air into a softer, more evenly distributed airflow, thereby reducing turbulence and wind resistance. This reduces the resistance that the exhaust assembly needs to overcome, achieving a more energy-efficient effect. In addition, when the airflow passes over a straight screen, it generates alternating vortices behind it, which are a significant source of noise. The irregular surface of the wavy design disrupts the formation of these regular vortices, thus reducing noise. The arc-shaped recess 51 of the top plate 11 and the arc-shaped recess 51 of the exhaust screen 5 are along their respective... The central axis of the top plate 11 is circumferentially opened, and the arc-shaped recess 51 of the top plate 11 and the arc-shaped recess 51 of the exhaust screen 5 fits the outer contour of the cat-teasing ball 151, so that the cat-teasing ball 151 can move circumferentially along the arc-shaped recess 51 of the top plate 11 and the arc-shaped recess 51 of the exhaust screen 5. The base 12 and the air inlet screen 7 are also provided with corresponding arc-shaped recesses 51 along their respective central axes, and the cat-teasing ball 151 is also provided between the arc-shaped recess 51 of the base 12 and the arc-shaped recess 51 of the air inlet screen 7. The cat-teasing ball 151 moves circumferentially between the arc-shaped recess 51 of the base 12 and the arc-shaped recess 51 of the air inlet screen 7.
[0047] Preferably, the exhaust assembly includes a motor 14, the exhaust screen 5 has a downward recessed center forming an installation cavity 52, the grille structure 4 has a screen bracket 6 fixedly connected to the wall of the installation cavity 52, the motor 14 is placed in the installation cavity 52 and fixedly connected to the screen bracket 6, so that the motor 14 is fixed in an independent chamber, which facilitates maintenance and replacement.
[0048] In a preferred embodiment, the grille structure 4 includes at least two sets of grille plates with different orientations. The grille plates allow external airflow to be drawn into the filter element 13 at multiple angles through the air inlet zone 41, and the purified airflow is diffused outwards at multiple angles through the air outlet zone 42. The air inlet area 41 of the grille structure 4 corresponds to the position of the filter element 13, and the air outlet area 42 of the grille structure 4 corresponds to the exhaust component. The grille group located in the air inlet area 41 and the grille group located in the air outlet area 42 are integrated structures and face the same direction as their respective grille groups. By setting grille groups with different orientations, outside air from different areas is drawn into the filter element 13 through the air inlet area 41, and then the filtered air is discharged upward through the air outlet area 42 inside the filter element 13. Since the grille group in the air outlet area 42 and the grille group in the air inlet area 41 are integrated structures, the filtered air can also be discharged to different areas. Using a set of independent grille structures 4 can achieve multi-angle air inlet and exhaust, which not only eliminates purification dead corners and improves purification efficiency, but also avoids setting up two sets of grille structures 4 for air intake and exhaust, saving production costs and optimizing equipment space utilization.
[0049] The above description is only a preferred embodiment of the present utility model.
