Description

Technical Field

[0001] This utility model relates to the field of lighting fixture technology, and in particular to an air purification component for a lamp and a lamp including the same. Background Technology

[0002] As people's quality of life continues to improve, their requirements for home appliances are also increasing. Among them, lamps are frequently used home lighting tools. Existing technology already includes lamps with air purification functions, which can not only provide light for the indoor environment but also purify the air and create a comfortable living environment.

[0003] Existing light fixtures with air purification functions, taking ceiling lights installed on the ceiling as an example, have a cavity containing a negative ion generator. Several ventilation holes are located at the bottom of the ceiling light, allowing negative ions released by the generator to circulate to the outside of the light fixture, thereby purifying the indoor space.

[0004] In existing lamps, most of the negative ions released by the negative ion generator cannot be discharged through the vent. Instead, they are confined within the cavity and slowly released, resulting in low air purification efficiency. This is especially true for air near the ground, where the initial velocity of the negative ions released from the lamp is low, and it takes a long time for the negative ions to travel to the ground. Consequently, users have to wait a long time to experience purified air. Utility Model Content

[0005] The main purpose of this invention is to propose an air purification component for lamps, which aims to solve the technical problem of low negative ion release efficiency in existing lamps.

[0006] To achieve the above objectives, this utility model proposes an air purification component for a lamp, including a purification installation structure, a negative ion device, and a purification protective cylinder; the negative ion device includes an electrically connected negative ion generator and a negative ion emitter, the negative ion generator is disposed on the purification installation structure, the lower end of the purification installation structure is provided with a guide cylinder with an opening facing downwards, the negative ion emitter includes a release brush, the release brush being at least partially located inside the guide cylinder; the purification protective cylinder has an upward-facing opening, the guide cylinder being at least partially located inside the purification protective cylinder, the bottom of the purification protective cylinder is provided with a first vent hole, the first vent hole is directly opposite the release brush, and the diameter D1 of the first vent hole is greater than the diameter d of the release brush.

[0007] The beneficial effects of this utility model are as follows: In this utility model, the release brush is at least partially disposed inside the guide tube, and the first vent is directly opposite the release brush, so that at least part of the negative ions released by the release brush flows into the first vent under the guidance of the guide tube, and can be smoothly released from the first vent to the outside of the lamp. This helps to increase the initial speed of negative ions released from the lamp and shorten the time it takes for negative ions to flow to the ground, thereby improving air purification efficiency and optimizing the user experience.

[0008] Preferably, the bottom of the guide tube and the purification and protection tube are spaced apart, and the bottom of the purification and protection tube is also provided with multiple second ventilation holes. The multiple second ventilation holes are arranged around the first ventilation hole, making the distribution of indoor negative ions more three-dimensional, thereby creating a more comfortable living environment.

[0009] Preferably, the diameter D1 of the first vent is 1.5 to 4 times the diameter d of the release brush, and the diameter D2 of the second vent is 1 to 2 times the diameter d of the release brush, so that the negative ion content in the room is more reasonably distributed according to the height, which is more in line with the user's living habits.

[0010] Preferably, the release brush extends in the vertical direction, and the lower end of the release brush protrudes from the lower end of the guide tube, which helps to further optimize the air purification effect.

[0011] Preferably, the purification installation structure includes an upward-facing installation cylinder, a negative ion generator disposed inside the installation cylinder, and an installation ring extending outward from the edge of the opening of the installation cylinder, the installation ring being used to install the purification installation structure onto the lamp.

The upper side of the diffuser is connected to the annular light source plate. The lower end of the diffuser is provided with a protective cylinder mounting through hole. The purification protective cylinder passes through the protective cylinder mounting through hole and is mounted on the diffuser. A first limiting part is provided on the inner wall of the protective cylinder mounting through hole, and a second limiting part is provided on the outer wall of the purification protective cylinder near its bottom. The first limiting part and the second limiting part are used to restrict the upward movement of the purification protective cylinder, which is beneficial to expanding the adaptability of the air purification component and reducing production costs.

[0014] Preferably, the lamp also includes a lampshade with its opening facing downwards.

[0024] like Figures 1 to 9As shown, an air purification component for a lamp includes a purification mounting structure 1, a negative ion device 2, and a purification protective cylinder 3. The negative ion device 2 includes an electrically connected negative ion generator 21 and a negative ion emitter 22. The negative ion generator 21 is mounted on the purification mounting structure 1. The lower end of the purification mounting structure 1 is provided with a guide cylinder 12 with its opening facing downwards. The negative ion emitter 22 includes a release brush 221, which is at least partially located inside the guide cylinder 12. The purification protective cylinder 3 has an upward-facing opening, and the guide cylinder 12 is at least partially located inside the purification protective cylinder 3. The bottom of the purification protective cylinder 3 is provided with a first vent hole 31, which is directly opposite the release brush 221, and the diameter D1 of the first vent hole 31 is larger than the diameter d of the release brush 221.

[0025] In this embodiment, the release brush 221 is at least partially disposed inside the guide tube 12, and the first vent 31 is directly opposite the release brush 221. This allows at least a portion of the negative ions released by the release brush 221 to flow into the first vent 31 under the guidance of the guide tube 12, and to be smoothly released from the first vent 31 to the outside of the lamp. This helps to increase the initial speed of negative ions released from the lamp and shorten the time it takes for negative ions to flow to the ground, thereby improving air purification efficiency and optimizing the user experience.

[0026] This embodiment uses a downlight as an example to describe the structure of an air purification component and a lamp with the air purification component installed.

[0027] In some specific embodiments, reference is made to Figure 4 and Figure 8 The bottom of the guide tube 12 is separated from the bottom of the purification and protection tube 3. The bottom of the purification and protection tube 3 is also provided with multiple second vent holes 32, which are arranged around the first vent hole 31.

[0028] In this embodiment, most of the negative ions released from the release brush 221 can be released to the outside of the lamp through the first vent 31, and the release distance is relatively long. The guide tube 12 and the bottom of the purification and protection tube 3 are spaced apart, and multiple second vents 32 are provided around the first vent 31. This allows some of the negative ions released from the release brush 221 to diffuse outwards between the bottom of the guide tube 12 and the purification and protection tube 3, and then be released to the outside of the lamp through the second vents 32. This arrangement allows the negative ions released by the lamp to diffuse more evenly to different heights within the room, making the distribution of negative ions more three-dimensional and creating a more comfortable living environment.

[0029] In some specific embodiments, reference is made to Figure 4 The diameter D1 of the first vent 31 is 1.5 to 4 times the diameter d of the release brush 221, and the diameter D2 of the second vent 32 is 1 to 2 times the diameter d of the release brush 221.

[0030] In this embodiment, there is a certain distance between the release brush 221 and the first vent 31. Therefore, in addition to satisfying the requirement that the diameter D1 of the first vent 31 is greater than the diameter d of the release brush 221, multiple practical tests have proven that when the diameter D1 of the first vent 31 is 1.5 to 4 times the diameter d of the release brush 221, most negative ions can be smoothly discharged from the lamp through the first vent 31. Combined with the condition that "the diameter D2 of the second vent 32 is 1 to 2 times the diameter d of the release brush 221," the indoor negative ion content will be more rationally distributed according to height, better conforming to the user's living habits. D1 is greater than D2.

[0031] In some specific embodiments, reference is made to Figure 8 The release brush 221 extends in the vertical direction, and the lower end of the release brush 221 protrudes from the lower end of the guide tube 12.

[0032] This setup ensures that the negative ions released by the release brush 221 are guided by the guide tube 12, while still allowing enough negative ions to be released from the second vent 32 to the outside of the lamp, which helps to further optimize the air purification effect.

[0033] In some specific embodiments, reference is made to Figure 1 and Figure 2 The purification installation structure 1 includes an upward-facing installation cylinder 11, a negative ion generator 21 located inside the installation cylinder 11, and an installation ring 13 extending outward from the edge of the opening of the installation cylinder 11. The installation ring 13 is used to install the purification installation structure 1 onto the lamp.

[0034] An installation cylinder 11 is provided to provide installation space for the negative ion generator 21 and to protect the negative ion generator 21. In this embodiment, the bottom of the installation cylinder 11 has a wire hole communicating with the guide cylinder 12, which is used for the wires connecting the negative ion generator 21 and the negative ion emitter 22 to pass through. The installation ring 13 has multiple installation holes, and the installation ring 13 can be installed on the lamp fixture by screws.

[0035] refer to Figures 5 to 9 This embodiment also provides a lamp, including an air purification component on the lamp.

[0036] In some specific embodiments, reference is made to Figure 5 , Figure 6 and Figure 8The lamp also includes a mounting plate 4, which is located on the upper side of the air purification component. The purification mounting structure 1 is mounted on the mounting plate 4. The mounting plate 4 is also provided with an annular light source plate 6 and a diffuser 7. The purification mounting structure 1 is located inside the annular light source plate 6. The annular light source plate 6 and the purification mounting structure 1 are located inside the diffuser 7. The upper side of the diffuser 7 is connected to the annular light source plate 6. The lower end of the diffuser 7 is provided with a protective cylinder mounting through hole 72. The purification protective cylinder 3 passes through the protective cylinder mounting through hole 72 and is mounted on the diffuser 7. The inner side wall of the protective cylinder mounting through hole 72 is provided with a first limiting part 721. The outer side wall of the purification protective cylinder 3 near its bottom is provided with a second limiting part 33. The first limiting part 721 and the second limiting part 33 are used to restrict the upward movement of the purification protective cylinder 3.

[0037] In this embodiment, the purification protective cylinder 3 is interference-fitted with the protective cylinder mounting through hole 72. The first limiting part 721 includes a first limiting ring disposed inside the protective cylinder mounting through hole 72, and the second limiting part 33 includes a second limiting ring disposed outside the purification protective cylinder 3. During installation, the purification protective cylinder 3 is inserted into the protective cylinder mounting through hole 72, and the purification protective cylinder 3 is pushed upward until the first limiting ring presses against the second limiting ring.

[0038] The purification protective cylinder 3 is installed on the diffuser 7, and the purification installation structure 1 is installed on the lamp plate, so that the installation of the air purification component can be adapted to diffusers 7 of different specifications, which is conducive to expanding the compatibility of the air purification component and reducing production costs.

[0039] In some specific embodiments, reference is made to Figure 8 The lamp also includes a lampshade 5 with its opening facing downwards. The annular light source plate 6, the diffuser 7, and the air purification component are all located inside the lampshade 5. The bottom surface of the purification protective cylinder 3, the bottom surface of the diffuser 7, and the bottom surface of the lampshade 5 are respectively referred to as the first bottom surface 34, the second bottom surface 711, and the third bottom surface 511. The first bottom surface 34 protrudes downwards from the second bottom surface 711 and the third bottom surface 511.

[0040] In this embodiment, the first bottom surface 34 protrudes downward from the second bottom surface 711 and the third bottom surface 511, so that the negative ions released from the bottom surface of the purification protective cylinder 3 will not be easily attracted by the bottom surface of the diffuser 7 and the bottom surface of the lampshade 5, thereby keeping the negative ions away from the wall or ceiling where the lamp is installed and avoiding the phenomenon of black walls.

[0041] Furthermore, the purification protective cylinder 3, the diffuser 7, and the lampshade 5 are all made of plastic, which can isolate high voltage static electricity and prevent the attraction of negative ions due to high voltage static electricity. While avoiding the black wall phenomenon, it also makes the flow of negative ions smoother.

[0042] In some specific embodiments, reference is made to Figure 8The lampshade 5 has a first ring body 51 on its lower side, and a third bottom surface 511 is located on the lower side of the first ring body 51. The diffuser 7 has a second ring body 71 on its lower side, and a second bottom surface 711 is located on the lower side of the second ring body 71. The distance L between the outer side of the second ring body 71 and the inner side of the first ring body 51 is ≥15mm.

[0043] The distance L ≥ 15 mm between the outer side of the second ring 71 and the inner side of the first ring 51 can effectively reduce the probability of negative ions flowing from the first ring 51 to the second ring 71, which is conducive to further reducing the probability of the black wall phenomenon.

[0044] In some specific embodiments, the lampshade 5 is at least partially made of a light-transmitting material, and a second light source structure is provided inside the lampshade 5.

[0045] In this embodiment, the second light source is an ambient light source. The ambient light emitted by the ambient light source can relieve visual fatigue and create a warm atmosphere. Combined with the air purification effect of the negative ion device 2, it further relaxes the user and optimizes the user experience.

[0046] refer to Figure 9 This embodiment also provides a ceiling light equipped with an air purification component.

[0047] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
