Description

Technical Field

[0001] This application belongs to the field of air purification technology, and more specifically, relates to an air purifier. Background Technology

[0002] Air purifiers play an important role in improving indoor air quality and protecting human health. For example, air purifiers can effectively remove various particulate matter in the air, such as dust, pollen, pet hair, mold spores, and industrial pollutants. They can also remove harmful gases in the air, such as formaldehyde, benzene, ammonia, and hydrogen sulfide. At the same time, they can also remove pollutants such as odors and smoke from the air, making the indoor air fresher and healthier.

[0003] To help users locate air purifiers at night or in dimly lit environments, or to help users understand the working status of the air purifier, some air purifiers have internal light-emitting components. The light emitted by these components shines outward through a light-transmitting cover. However, some of the light emitted by these components can easily leak out from around the components, except from other locations besides the light-transmitting cover. For example, it can easily leak out from a weak point in the non-light-transmitting cover adjacent to the light-transmitting cover. In addition, when the light-emitting component's light direction deviates from the position of the light-transmitting cover, the light emitted by the component can also easily leak out from the direction of the light-transmitting component's light direction. As a result, the light emitted from the light-transmitting cover is not bright enough and the lighting effect is poor. Furthermore, when the component is emitting light at night or in dimly lit environments, it can also affect the aesthetics of the air purifier's external light, thus leading to a poor user experience.

When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0030] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0031] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0032] Please refer to the following: Figures 1 to 5 The air purifier provided in the embodiments of this application will now be described. The air purifier includes: a housing 10, a light-transmitting lampshade 20, and a light-shielding component 30.

[0033] Please refer to the following: Figures 1 to 3The purification component 70 is disposed inside the housing 10; the light-transmitting lamp cover 20 is connected to the housing 10, and the light-transmitting lamp cover 20 includes a light-transmitting part 21, which is exposed outside the housing 10; the light-shielding component 30 is disposed inside the housing 10, and the light-shielding component 30 and the light-transmitting part 21 form a light-emitting area 40; the light-emitting element 50 is disposed inside the light-emitting area 40, and the light emitted by the light-emitting element 50 is emitted through the light-transmitting part 21.

[0034] Please refer to Figure 1 and Figure 2 The housing 10 has multiple air inlets 123 on its peripheral sidewalls and multiple air outlets 112 on its top. The air purifier also includes a purification component 70, which is disposed between the air inlets 123 and the air outlets 112. Air enters the housing 10 through the air inlets 123, the purification component 70 purifies the air, and the purified air is discharged through the air outlets 112.

[0035] The housing 10 is provided with a light outlet 111, and the light-transmitting part 21 is sealed in the light outlet 111, that is, the light-transmitting part 21 is exposed to the housing 10 through the light outlet 111. By sealing the light outlet 111 with the light-transmitting part 21 of the light-transmitting lamp cover 20, external impurities are prevented from entering the housing 10 from the light outlet 111, while allowing the light emitted by the light-emitting element 50 to be emitted from the light outlet 111.

[0036] It should be noted that the light-emitting element 50 can function as either a lamp or a work indicator light. When used as a lamp, the light-emitting element 50 provides illumination, making it easy for users to locate the air purifier at night or in dimly lit environments, thus enhancing user convenience. When used as a work indicator light, the illuminated state of the light-emitting element 50 indicates the air purifier's operating status. For example, when the light-emitting element 50 is illuminated, it indicates that the air purifier is working and purifying the air; when the light-emitting element 50 is not illuminated, it indicates that the air purifier is not working. In addition, when the light-emitting element 50 is used as a work indicator, the current air quality can be indicated by different light-emitting modes of the light-emitting element 50. For example, when the light-emitting element 50 emits green light, it indicates that the surrounding air quality is good, and when the light-emitting element 50 emits red light, it indicates that the surrounding air quality is poor. Of course, other light-emitting modes of the light-emitting element 50 can also be used to indicate the current air quality, such as the number of lights emitted by the light-emitting element 50.

[0037] Compared with the prior art, the air purifier provided in this application has a purification component 70 for purifying air. By setting a light-shielding component 30 inside the housing 10, and the light-shielding component 30 and the light-transmitting part 21 forming a light-emitting area 40, and the light-emitting element 50 is set in the light-emitting area 40, when the light-emitting element 50 emits light, it illuminates the light-emitting area 40. The light in the light-emitting area 40 is emitted through the light-transmitting part 21. Since the light-shielding component 30 has a light-shielding function, the light in the light-emitting area 40 is difficult to pass through the light-shielding component 30, thereby effectively preventing the light emitted by the light-emitting element 50 from being transmitted outward from the housing 10, that is, effectively avoiding light leakage. This makes the light emitted by the light-emitting element 50 through the light-transmitting part 21 more bright and has a better lighting effect. At the same time, when the light-emitting element 50 emits light at night or in a dim environment, there is no light leakage, which helps to improve the aesthetics of the air purifier and thus improve the user experience.

[0038] In another embodiment of this application, please refer to Figure 2 and Figure 3 The housing 10 is provided with a receiving groove 121, and the light-emitting element 50 is housed in the receiving groove 121. The light-shielding assembly 30 includes a first light-shielding cover 31, which covers the side wall of the receiving groove 121 near the outside of the housing 10 and the side of the light-emitting element 50 away from the light-emitting area 40.

[0039] Optionally, the first light shield 31 is approximately L-shaped. Of course, the first light shield 31 can also be other shapes, depending on the position and direction of the light-emitting element 50.

[0040] By covering the side wall of the receiving groove 121 near the outside of the housing 10 with the first light shield 31, the first light shield 31 can absorb the light emitted by the light-emitting element 50 towards the side of the receiving groove 121 near the outside of the housing 10. By covering the side of the light-emitting element 50 away from the light-emitting area 40 with the first light shield 31, the first light shield 31 can absorb the light reflected back from the opposite part of the light-emitting area 40 and the light-emitting element 50. For example, when the light-emitting element 50 is located below the light-emitting area 40 and the light-emitting direction of the light-emitting element 50 is upward, the first light shield 31 can absorb the light reflected back from the upper side of the light-emitting area 40; when the light-emitting element 50 is located above the light-emitting area 40 and the light-emitting direction of the light-emitting element 50 is downward, the first light shield 31 can absorb the light reflected back from the lower side of the light-emitting area 40.

[0041] By placing the light-emitting element 50 in the receiving groove 121, the light-emitting element 50 is positioned. The first light shield 31 covers the side wall of the receiving groove 121 near the outside of the housing 10 and the side of the light-emitting element 50 away from the light-emitting area 40, effectively preventing the light emitted by the light-emitting element 50 from leaking out from the side of the receiving groove 121 near the outside of the housing 10 and the position of the light-emitting element 50 away from the light-emitting area 40.

[0042] In another embodiment of this application, the first light shield 31 is a dark plastic light shield.

[0043] Optionally, the first light shield 31 is made of black plastic material, which provides good light-blocking effect. Of course, in other embodiments, the first light shield 31 can also be made of dark-colored plastic material such as dark blue, gray, or dark green. In addition, the plastic material used for the first light shield 31 can be polyvinyl chloride (PVC) or polycarbonate (PC), etc.

[0044] In another embodiment of this application, please refer to Figure 3 and Figure 4 The light-transmitting part 21 is provided on the peripheral side wall of the housing 10 and is arranged in a ring along the circumference of the housing 10. The light-emitting element 50 is a ring-shaped light strip and is provided on the lower side or the upper side of the light-emitting area 40. At least part of the first light shield 31 covers the upper side or the lower side of the light-emitting element 50.

[0045] Optionally, the housing 10 is generally cylindrical, and the light outlet 111 is generally located at the middle position of the housing 10 along its own length. That is, the light-transmitting lamp cover 20, the light-shielding component 30 and the light-emitting component 50 are all generally located at the middle position of the housing 10 along its own length. Since the housing 10 has enough space inside at the middle position along its own length to accommodate part of the light-transmitting lamp cover 20, the light-shielding component 30 and the light-emitting component 50, it is not necessary to increase the diameter of the housing 10, and thus not necessary to increase the overall volume of the air purifier.

[0046] The shape of the light-transmitting part 21 is set according to the shape of the light-emitting port 111. When the light-emitting port 111 is arranged in a ring along the circumference of the housing 10, the light-transmitting part 21 is also a ring structure, and the light-transmitting part 21 seals the light-emitting port 111 along the circumference of the housing 10. The shape of the receiving groove 121 is set according to the shape of the light-emitting element 50. When the light-emitting element 50 is a ring-shaped light strip, the receiving groove 121 is arranged in a ring along the circumference of the housing 10.

[0047] Understandably, the first light shield 31 is also annular in shape, and it covers the side wall of the receiving groove 121 near the outside of the housing 10 and the side of the light-emitting element 50 away from the light-emitting area 40 along the circumference of the housing 10. For example, when the light-emitting element 50 is located below the light-emitting area 40, it emits light upwards, and the first light shield 31 covers the side wall of the receiving groove 121 near the outside of the housing 10 and the lower surface of the light-emitting element 50 along the circumference of the housing 10. When the light-emitting element 50 is located above the light-emitting area 40, it emits light downwards, and the first light shield 31 covers the side wall of the receiving groove 121 near the outside of the housing 10 and the upper surface of the light-emitting element 50 along the circumference of the housing 10.

[0048] It should be noted that in other embodiments of this application, the light-emitting element 50 can also be a ring-shaped light strip. When the light-emitting element 50 is a ring-shaped light strip, it can be directly and horizontally aligned with the light-transmitting portion 21, so that the light-emitting element 50 emits light in the horizontal direction. Additionally, the light-emitting element 50 can also be other shapes, such as a plate, which can be selected according to actual usage requirements.

[0049] In another embodiment of this application, please refer to Figure 3 The light-transmitting lamp cover 20 also includes an extension 22 that connects to the light-transmitting portion 21. The extension 22 is housed in the receiving groove 121 and is located on the side of the light-emitting element 50 facing the light-emitting area 40. At least a portion of the first light shield 31 is located between the extension 22 and the side wall of the receiving groove 121 near the outside of the housing 10.

[0050] Optionally, the extension 22 is L-shaped and integrally formed with the light-transmitting part 21. Both the extension 22 and the light-transmitting part 21 are made of transparent material and have good light transmittance.

[0051] In another embodiment of this application, please refer to Figure 2 and Figure 3 The light-shielding assembly 30 also includes a second light-shielding cover 32, which is located on the side of the light-emitting area 40 opposite to the light-emitting element 50 and on the side of the light-emitting area 40 near the center of the housing 10.

[0052] For example, when the light-emitting element 50 is positioned below the light-emitting area 40, a portion of the second light-shielding cover 32 is located above the light-emitting area 40, and another portion of the second light-shielding cover 32 is located on the side of the light-emitting area 40 closer to the center of the housing 10. This allows the second light-shielding cover 32 to absorb light emitted from the bottom of the housing 10 and light entering the housing 10. Similarly, when the light-emitting element 50 is positioned above the light-emitting area 40, a portion of the second light-shielding cover 32 is located below the light-emitting area 40, and another portion of the second light-shielding cover 32 is located on the side of the light-emitting area 40 closer to the center of the housing 10. This allows the second light-shielding cover 32 to absorb light emitted from the top of the housing 10 and light entering the housing 10.

[0053] By placing the second light shield 32 on the side of the light-emitting area 40 opposite to the light-emitting element 50 and on the side of the light-emitting area 40 close to the center of the housing 10, the second light shield 32 can absorb the light emitted from the relative position of the housing 10 and the light emitted into the housing 10. That is, by cooperating with the first light shield 31, the second light shield 32 effectively prevents the light in the light-emitting area 40 from leaking out of the housing 10, so that the light in the light-emitting area 40 is emitted only from the position of the light-transmitting part 21 as much as possible, which is beneficial to improving the lighting effect at the position of the light-emitting area 40.

[0054] In another embodiment of this application, please refer to Figure 3 and Figure 5 The second light shield 32 includes a light shielding part 321, a first light shielding rib 322 and a second light shielding rib 323. The air purifier also includes an air guide 60 disposed in the housing 10. The light shielding part 321 is the part of the air guide 60 corresponding to the light-emitting area 40. The first light shielding rib 322 is disposed between one end of the light shielding part 321 and the end of the light-transmitting part 21 away from the first light shield 31. The second light shielding rib 323 is disposed between the other end of the light shielding part 321 and the first light shield 31.

[0055] The air guide cover 60 is made of dark plastic material, which gives the air guide cover 60 a good light-blocking effect. In this way, the part of the air guide cover 60 corresponding to the light-emitting area 40 can be used as a light-blocking part 321. There is no need to set an additional light-blocking part 321 at the position of the air guide cover 60 corresponding to the light-emitting area 40, which helps to save costs and reduce the space occupied by the light-emitting component in the internal space of the housing 10.

[0056] Optionally, the air guide cover 60 is made of black plastic material, which provides good light blocking. Of course, in other embodiments, the air guide cover 60 can also be made of dark-colored plastic material such as dark blue, gray, or dark green. In addition, the plastic material used for the air guide cover 60 can be polyvinyl chloride (PVC) or polycarbonate (PC), etc.

[0057] The first light-shielding rib 322 and the second light-shielding rib 323 are made of black plastic, providing good light-shielding effect. Of course, in other embodiments, the first light-shielding rib 322 and the second light-shielding rib 323 can also be made of dark-colored plastic materials such as dark blue, gray, or dark green. Furthermore, the plastic material used for the first light-shielding rib 322 and the second light-shielding rib 323 can be polyvinyl chloride (PVC) or polycarbonate (PC), etc.

[0058] By placing the first light-shielding rib 322 between one end of the light-shielding part 321 and the end of the light-transmitting part 21 away from the first light-shielding cover 31, the first light-shielding rib is used to absorb the light emitted from the relative position of the light-emitting area 40 and the light-emitting element 50, effectively preventing the light in the light-emitting area 40 from leaking out from the gap between the light-shielding part 321 and the light-transmitting part 21 or between the light-shielding part 321 and the housing 10.

[0059] By placing the second light-shielding rib 323 between the other end of the light-shielding part 321 and the first light-shielding cover 31, the first light-shielding rib 322 cooperates with the light-shielding part 321 to absorb the light incident into the housing 10, thereby effectively preventing the light in the light-emitting area 40 from leaking out of the housing 10.

[0060] In another embodiment of this application, please refer to Figures 1 to 5 The light-shielding part 321, the first light-shielding rib 322 and the second light-shielding rib 323 are integrally formed.

[0061] The materials of the first light-shielding rib 322 and the second light-shielding rib 323 are integrally formed with the material of the air guide cover 60, so that the light-shielding part 321, the first light-shielding rib 322 and the second light-shielding rib 323 can be integrally formed. The process is simple, it is easy to assemble the second light-shielding cover 32, and at the same time, it makes the overall structure of the air purifier better.

[0062] Optionally, the light-shielding part 321 is an annular structure arranged along the circumference of the housing 10. The first light-shielding rib 322 and the second light-shielding rib 323 can be an annular structure arranged along the circumference of the housing 10, or multiple first light-shielding ribs 322 can be arranged along the circumference of the housing 10 to form an approximately annular structure, and multiple second light-shielding ribs 323 can be arranged along the circumference of the housing 10 to form an approximately annular structure.

[0063] In another embodiment of this application, please refer to Figure 3 The housing 10 has a slot 122 inside, which is located on the side of the receiving groove 121 near the center of the housing 10. The second light-shielding rib 323 is inserted into the slot 122.

[0064] Specifically, please refer to Figures 1 to 3The housing 10 includes a first housing part 11 and a second housing part 12 connected to each other. The first housing part 11 and the second housing part 12 are distributed along the length direction of the housing 10. A light-transmitting lamp cover 20 is disposed between the first housing part 11 and the second housing part 12. A first light shield 31 is disposed on the first housing part 11, and a second light shield 32 is disposed on the second housing part 12. The first light shield 31, the second light shield 32 and the light-transmitting part 21 of the light-transmitting lamp cover 20 cooperate to form a light-emitting area 40. A light-emitting element 50 is disposed on the first housing part 11 or the second housing part 12.

[0065] Optionally, one end of the first housing portion 11 and the second housing portion 12 are detachably connected. A light outlet 111 is located at one end of the second housing portion 12 near the first housing portion 11. A light-transmitting lampshade 20 is fixed to the second housing portion 12; for example, the light-transmitting lampshade 20 is snapped onto the second housing portion 12, and the air guide 60 is connected to the second housing portion 12 by screws. Both the receiving groove 121 and the slot 122 are located at one end of the first housing portion 11 near the second housing portion 12. A first light shield 31 is fixed within the receiving groove 121, and the light-emitting element 50 is fixedly connected to the first light shield 31, such as by screws.

[0066] By setting the first light shield 31 on the first housing part 11 and the second light shield 32 on the second housing part 12, the first light shield 31, the second light shield 32 and the light-transmitting lamp cover 20 cooperate to form a light-emitting area 40, effectively preventing the light emitted by the light-emitting element 50 from being emitted from the positions of the first housing part 11 and the second housing part 12, and effectively avoiding light leakage.

[0067] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
