[0028] The following will make a detailed description of the present utility model in conjunction with the accompanying drawings and specific embodiments.

[0029] The present utility model provides a telescopic air - purifying lamp, as Figures 1 to 6 shown, which includes a purification module 1 and a plurality of lighting modules 2 annularly distributed on the front side of the purification module 1.

[0030] As Figure 1 shown, the purification module 1 includes a main housing. An air suction port 111 is provided in the middle of the main housing, and a fan 15 for generating negative pressure is provided inside the main housing. Indoor air in a chess room, etc., is sucked into the main housing through the air suction port 111 and is effectively filtered by an internal filtration system (such as a HEPA filter, an activated carbon layer, etc.) to remove dust, odors and some harmful gases in the air, and fresh air is released. A suspension rod can be connected to the main housing, and the suspension rod is used to suspend the entire air - purifying lamp from the ceiling.

[0031] As Figure 2As shown, the outer periphery of the purification module 1 is designed to be circular. Specifically, the main housing includes a front housing 11 and a rear housing 12, both of which are annular. A front ventilation hood 13 is provided in the middle of the annular front housing 11, and a rear ventilation hood 14 is provided in the middle of the annular rear housing 12. The fan 15 is located in the space formed by the front ventilation hood 13 and the rear ventilation hood 14. Of course, the purification module 1 can also be of other shapes, which is not limited in this case.

[0032] The lighting module 2 includes a lamp holder 21, a lighting component (not shown in the figure), and a lamp shade 22. The lamp holder 21 has an opening, and the lighting component is fixed inside the lamp holder 21. The lighting component can adopt an LED lighting component to achieve an energy-saving and bright lighting effect. The lamp shade 22 is fastened to the opening of the lamp holder 21 through a snap structure. The snap structure not only facilitates the replacement of the light bulb or cleaning and maintenance, but also enhances the overall stability and aesthetics.

[0033] The lighting module 2 is slidably and telescopically arranged on the purification module 1. The specific structure is as follows: As Figure 3 and Figure 4 shown, a tooth groove 221 extending radially along itself is provided at the rear side of the lamp holder 21 of the lighting module 2. A motor 16 is fixed inside the main housing. The output shaft of the motor 16 penetrates the wall of the front housing 11 and extends towards the lighting module 2, and a gear 17 is sleeved and connected to the end. The gear 17 is in close meshing with the tooth groove 221. The motor 16 is electrically connected to an intelligent controller (not shown in the figure) and realizes intelligent control. When the motor 16 works, through the interaction between the gear 17 and the tooth groove 221, it can drive the lighting module 2 to perform telescopic movement along the front side of the purification module 1, approaching or moving away from the middle of the purification module 1, so as to realize the gathering or unfolding of multiple lighting modules 2 on the purification module 1. This design enables the user to easily adjust the position of the lighting module 2. Whether gathering multiple lighting modules 2 to provide a concentrated and strong light source or unfolding them to expand the lighting range can be easily achieved. The gathering and unfolding states can be referred to Figure 5 and Figure 6 .

[0034] In order to improve the running stability and accuracy of the lighting module 2 in the retractable air purification lamp. In this design, as Figure 3 and Figure 4 shown, a telescopic guide rail is further provided between the main housing and the lighting module 2. The telescopic guide rail includes a running guide rail 23 and a main guide rail 18. The running guide rail 23 is fixed on the lighting module 2, and the main guide rail 18 is fixed on the front housing 11. The running guide rail 23 is connected to the main guide rail 18. When the lighting module 2 moves, the running guide rail 23 slides along the main guide rail 18. This design ensures that no matter whether the lighting module 2 is gathered or unfolded, it can move along the established track, avoiding deviation or shaking. Here, the number of telescopic guide rails corresponding to each lighting module 2 is at least one group, and can also be multiple groups. In this embodiment, as Figure 3 andFigure 4 As shown, each lighting module 2 corresponds to two sets of telescopic guide rails. The two sets of telescopic guide rails are respectively located on the left and right sides of the tooth groove 221 of the gear 17, forming a balanced and stable support structure.

[0035] To achieve the precise installation and positioning of the guide rail system, as shown in Figure 3 and Figure 4 shown, a linear groove 222 is also provided on the lighting module. The shape of the linear groove 222 matches that of the running guide rail 23, providing a stable installation foundation for the running guide rail 23. Similarly, a linear rib 112 is also protruded on the front housing 11 for the stable installation of the main guide rail 18.

[0036] To further limit the movement range of the lighting module 2 and improve its stability, the design also introduces a combination of a limit block 223 and a relief groove 113. As shown in Figure 3 and Figure 4 shown, the limit block 223 protruded on the lamp holder 21 of the lighting module 2 is embedded in the relief groove 113 provided on the front housing 11, forming a limit mechanism. When the lighting module 2 slides along the main guide rail 18 driven by the motor 16, the limit block 223 will slide along the trajectory of the relief groove 113, thus ensuring that the movement of the lighting module 2 always remains within a predetermined range and avoiding damage or failure caused by excessive movement.

[0037] In this embodiment, as shown in Figure 2 and Figure 3 shown, the tooth groove 221, the running guide rail 23, and the linear groove 222 on the lamp holder 21 are all located on its rear surface, that is, they do not penetrate the wall of the lamp holder 21 and are not likely to interfere with the lighting components inside the lamp holder 21.

[0038] In this embodiment, a single lighting module 2 is in a fan-shaped ring. The number of lighting modules 2 on the purification module 1 is four, and they are symmetrically and spaced apart. Each lighting module 2 is driven by a motor 16, and each motor 16 is electrically connected to the intelligent controller, enabling the simultaneous movement of the lighting modules 2 or separate movement. When the purification mode is not required, the lighting modules 2 can be gathered towards the middle. After the lighting modules 2 are completely gathered (as shown in Figure 5 shown), a circle smaller than or equal to the area of the purification module 1 is formed, minimizing the overall occupied space of the air purifier as much as possible, and being able to block part of the air intake 111, reducing the possibility of dust entering the air intake 111, helping to keep the inside of the air purifier clean and extending its service life.

[0039] To further illustrate the embodiments, the present utility model provides accompanying drawings. These drawings are a part of the disclosure of the present utility model, mainly used to illustrate the embodiments and can be combined with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those of ordinary skill in the art should be able to understand other possible implementation manners and the advantages of the present utility model. The components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0040] Meanwhile, the front, rear, left, right and other orientations involved in this embodiment are only for reference of an orientation and do not represent the orientation in actual use. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0041] The above are only the preferred embodiments of the present utility model and do not limit the design of this case. All equivalent changes made according to the key design of this case fall within the protection scope of this case.
