[0033] The following describes the embodiments of the present application in conjunction with the accompanying drawings. It should be understood that the embodiments described below in conjunction with the accompanying drawings are exemplary descriptions for explaining the technical solutions of the embodiments of the present application and do not constitute a limitation on the technical solutions of the embodiments of the present application.

[0034] Those skilled in the art will understand that, unless otherwise stated, the terms "said" and "the" used herein may also include plural forms. It should be further understood that the term "including" used in the specification of this application refers to the presence of the features, integers and / or components, but does not exclude the implementation of other features, information, data, steps, operations, elements, components and / or their combinations supported by the technical field. The term "and / or" used herein refers to at least one of the items defined by the term, for example, "A and / or B" can be implemented as "A", or as "B", or as "A and B".

[0035] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0036] refer to Figures 1 to 7The present application provides a ceiling lamp, comprising a ceiling lamp housing 1, a ventilation module 2, a plasma generating module 3, a lighting module 4 and a control module 5, wherein the control module 5 is electrically connected to the ventilation module 2, the plasma generating module 3 and the lighting module 4 to realize intelligent control of these three functional modules.

[0037] Furthermore, the ceiling lamp housing 1 includes a bottom shell 11 for wall hanging, and a surface shell 12 for light and air transmission, wherein the surface shell 12 is provided with an air inlet 121 and an air outlet 122. The "wall hanging" involved in this application includes the case of hanging on the ceiling and the case of hanging on the wall. Therefore, this application also includes a wall hanging module 6, which has a universal feature that can adapt to the application scenarios of hanging on the ceiling and wall without the need to replace accessories.

[0038] refer to Figures 2 to 6 The ceiling lamp housing 1 and the ventilation module 2 constitute the ventilation cavity structure of the present application. The ventilation module 2 includes an inner support 21 fixed inside the ceiling lamp housing 1 and a fan 22 assembled on one side of the inner support 21. The ventilation module 2 is used to connect the air inlet 121 and the air outlet 122 to form an air guide channel. Figure 7 The inner support 21 includes a base plate 211 arranged parallel to the surface shell 12 and a pair of support plates 212 extending vertically from the upper surface of the base plate 211. The space enclosed by the base plate 211, the pair of support plates 212 and the bottom shell 11 is adapted to the minimum size of the air guide channel formed by the fan 22. Optionally, the spacing between the pair of support plates 212 is adapted to the minimum width of the air guide channel of the fan 22, and the height of each support plate 212 is adapted to the minimum height of the air guide channel. This embodiment adopts an axial flow fan 22. Accordingly, the spacing between the pair of support plates 212 can be the same as the axial length of the fan 22, the height of the support plate 212 can be slightly larger than the diameter of the fan 22, and the bottom shell 11 can abut against the upper edge of the support plate 212. Preferably, the base plate 211 is provided with a second avoidance opening 213 for the installation of the fan 22. The fan 22 is fixed to the second avoidance opening 213 by the fan 22 mounting end plate, so that the fan 22 is not lower than the horizontal plane of the base plate 211 after assembly. Those skilled in the art know that a certain gap should be reserved between the fan 22 and the closed side wall to facilitate the operation and diversion of the fan 22. Therefore, the size of the fan 22 mounting end plate can be slightly larger than the cross section of the fan 22, and the height of the fan 22 mounting end plate is flush with the support plate 212. The shape of the second avoidance opening 213 can be adapted to the outer contour of the longitudinal section of the fan 22, and face the air outlet 122, so that the fan 22 faces the air outlet 122. The support plate 212 is not required to be flush with the longitudinal edge of the base plate 211. The range between the longitudinal edges of the support plate 212 and the base plate 211 can be reserved for assembly and docking with other structures of the ceiling lamp.

[0039] Preferably, the air inlet 121 and the air outlet 122 are arranged on opposite sides of the housing 12, and an air inlet grille 23 is provided at the air inlet 121, and an air outlet grille 26 is provided at the air outlet 122. The air inlet grille 23 and the air outlet grille 26 can block the air guide channel without affecting ventilation, thereby preventing foreign matter from entering the air guide channel and affecting the internal structure of the ceiling lamp. Figure 8 The air inlet 121 is further provided with an air inlet bracket 24. The air inlet grille 23 is detachably connected to the air inlet bracket 24 to facilitate removal of the air inlet grille 23. A filter layer 25 can be placed inside the air inlet grille 23, and the filter layer 25 is fixed to the first avoidance opening 243 of the air inlet bracket 24 by a stopper 242. When the air inlet grille 23 is removed, the filter layer 25 can be replaced. The air inlet grille 23 and the air inlet bracket 24 can be fixed by a press-type snap fastener. One feasible implementation method is to provide a slot in the air inlet bracket 24, and provide a corresponding snap fastener and positioning member on the air inlet grille 23. The positioning member and snap fastener are respectively installed in correspondence with the slot, thereby achieving the fixation of the air inlet grille 23 on the air inlet bracket 24. Pressing the snap fastener causes the snap fastener to deform, so that the snap fastener can be removed from the slot, thereby achieving the removal of the air inlet grille 23. The retaining members 242 for securing the filter layer 25 can be a pair of angled members fixed to the edge of the first avoidance opening 243 of the air inlet bracket 24. The vertical portion of the angled members is fixed to the edge of the first avoidance opening 243, and the horizontal portion of the angled members protrudes from the first avoidance opening 243. The filter layer 25 is clamped between the air inlet grille 23 and the angled members, and can be fixed without displacement. The shape of the first avoidance opening 243 is adapted to the outer contour of the air inlet grille 23, and the cross-sectional shape of the filter layer 25 should also be adapted to the outer contour of the air inlet grille 23. The air inlet bracket 24 also includes a pair of legs 241 of the same height as the inner support 21. Preferably, the pair of legs 241 are provided on either side of the first avoidance opening 243. The spacing between the pair of legs 241 is the same as the spacing between the pair of support plates 212, so that the air inlet bracket 24 serves as the entrance to the air guide channel.

[0040] In the ventilation cavity structure of the present application, when the fan 22 is started, the air near the fan 22 is driven to flow toward the air outlet 122, forming a negative pressure in the upstream space of the fan 22, and the air is replenished to the negative pressure area from the air inlet 121, thereby forming a unidirectional air flow in the air guide channel.

[0041] The ceiling lamp of the present application includes a plasma generating module 3, including a plasma generating assembly 31. Specifically, the plasma generating module 3 is arranged on the side of the air inlet of the fan 22 and close to the air outlet 122, so that the plasma generated by the plasma generating module 3 flows out of the air outlet 122 with the air in the air guide channel, and diffuses into the indoor space outside the ceiling lamp under the drive of the fan 22, thereby achieving the plasma purification effect. Preferably, the plasma generating module 3 is mounted on the inner side surface of the inner side of the bottom shell 11 from the outside via a first assembly plate 32. This has the advantage of facilitating replacement of the plasma generating module 3. Persons skilled in the art will appreciate that the various components in the plasma generating module 3 are consumable materials and require regular replacement to maintain the concentration of plasma generated and achieve a good air purification effect. The plasma generating assembly 31 is completely assembled on the first assembly plate 32, making it easy to remove the entire assembly via the first assembly plate 32. Furthermore, the first assembly plate 32 is connected to the bottom shell 11 from the outside to the inside, meaning that the first assembly plate 32 can be removed from the outer side surface of the bottom shell 11, eliminating the need to disassemble the entire ceiling lamp housing 1 and enabling replacement of the plasma generating assembly 31. Reducing the need to disassemble the ceiling lamp housing 1 helps ensure the integrity of the air guide duct and prevents disassembly and reassembly from affecting the operation of the fan 22 and increasing noise.

[0042] The lighting module 4 is mounted on the inner side of the face shell 12 and is used to provide lighting. Preferably, it includes a spotlight assembly 41 and an LED lamp assembly 42. Correspondingly, the face shell 12 is at least partially made of a translucent material to facilitate the transmission of light emitted by components such as LEDs. More preferably, the translucent material can be softened to adapt to use in indoor environments. The face shell 12 also provides a third avoidance opening 123 for facilitating the installation of the spotlight assembly 41. The spotlight assembly 41 can be assembled centrally, and correspondingly, the third avoidance opening 123 only needs to be configured with a larger one to accommodate the entire spotlight assembly 41; it can also be dispersedly assembled on the face shell 12. In this case, the third avoidance opening 123 needs to be configured with multiple smaller openings that are adapted to a single lamp head; in addition, when the space between the inner support 21 and the face shell 12 cannot completely accommodate the spotlight assembly 41, a corresponding avoidance opening can be further opened on the base plate 211 of the inner support 21. In this embodiment, the spotlight assembly 41 is centrally assembled at the center of the panel. If the ceiling lamp has a rectangular outer contour, the spotlight assembly 41 can be configured with two or three lamp heads in a direction parallel to the long side of the rectangle (e.g. Figure 1 As shown), if the ceiling lamp has a square outer contour, the spotlight assembly 41 can be configured with a pair of lamp holders or a lamp holder at the geometric center of the square (as shown in FIG. Figure 9 shown).

[0043] The control module 5 is mounted on the inner side of the bottom shell 11 and is used to control the start, shut down, and operating mode of the ventilation module 2, plasma module 3, and illumination module 4. Preferably, the control module 5 is electrically connected to the ventilation module 2, plasma module, and illumination module 4 to ensure stable power supply and communication. In this embodiment, the control module 5 is completely mounted on the second assembly plate 51, which is convenient for removal as a whole through the second assembly plate 51. The second assembly plate 51 is connected to the bottom shell 11 from the outside to the inside. In addition, according to the use characteristics of the control module 5, the control module 5 can be further mounted on the outer surface of the second assembly plate 51. The second assembly plate 51 is configured as a concave structure so that the relevant parts of the control module 5 remain flush with the outer surface of the bottom shell 11 after being assembled to the bottom shell 11 of the ceiling lamp. Assembling the control module 5 in this way facilitates debugging of the various functional modules of the ceiling lamp, avoids the need to disassemble the ceiling lamp housing 1 during the debugging phase after assembly, which affects the integrity of the air guide channel, and avoids affecting the operation of the fan 22 after disassembly and reassembly, resulting in increased noise.

[0044] The housing 1 of the ceiling lamp further comprises a middle shell 13 respectively connected to the bottom shell 11 and the front shell 12, and the middle shell 13 comprises a shell wall enclosing a ring. The provision of the middle shell 13 enables the housing of the ceiling lamp to achieve a richer combination according to the function of the ceiling lamp. For example, the middle shell 13 can adjust the height of the inner cavity of the ceiling lamp by adjusting the height of the shell wall, or be used to adjust the size of the air guide channel. The middle shell 13 can also be used to adjust the shape of the ceiling lamp. When the outer contour of the bottom shell 11 is inconsistent with the outer contour of the front shell 12, the middle shell 13 can be used to achieve a gradual transition. The middle shell 13 and the front shell 12 can be made of lightweight materials to achieve the overall lightweight of the ceiling lamp. The middle shell 13 and the front shell 12 can be made of special materials to adapt to the unique functions of the ceiling lamp. For example, the middle shell 13 and / or the front shell 12 use a coating material with anti-plasma adhesion to improve the plasma air purification effect of the ceiling lamp.

[0045] The wall-mounted module 6 includes an assembled mounting connection base and a fixing bracket 63 fixed to the wall-mounted position. Figure 10 The mounting connection seat includes a U-shaped seat 61 and a circular seat 62 that can be assembled inside the U-shaped seat 61 by sliding in. More specifically, the U-shaped seat 61 includes a pair of mirror-symmetrical straight arm portions and a curved arm portion connected to the same side of the straight arm portions, and the straight arm portion and the curved arm portion respectively extend a limiting wall toward the center position of the mounting connection seat on the appearance surface; the circular seat 62 includes a circular embedded portion assembled in the assembly space formed by the straight arm portion and the curved arm portion, and an extension portion extending out of the appearance surface. The straight arm portion and the curved arm portion of the U-shaped seat 61 are respectively provided with a through mounting hole for fixed connection with the bottom shell 11 of the ceiling lamp; the extension portion of the circular seat 62 is provided with a connecting structure for fixed connection with the fixing bracket 63.

[0046] When using the wall-mounted module 6 to install a ceiling lamp on the ceiling, due to the large size of the ceiling lamp, it is usually necessary to use two or more mounting connection bases to achieve fixation on the ceiling. One possible implementation method is that the circular seat 62 in the mounting connection base is pre-connected with the fixed bracket 63 on the ceiling, the U-shaped seat 61 is pre-connected with the back of the ceiling lamp, and the opening directions of all U-shaped seats 61 are consistent and parallel to each other. The assembly method is to align the U-shaped seat 61 with the circular seat 62 one by one and then push the ceiling lamp horizontally so that the circular seat 62 slides into the U-shaped seat 61 to achieve fixation. When using the wall-mounted module 6 to install the ceiling lamp on the wall, so that when the ceiling lamp is used in the form of a wall lamp, the circular seat 62 in the mounting connection base is pre-connected with the fixed bracket 63 on the wall, the U-shaped seat 61 is pre-connected with the back of the wall lamp, and the opening of the U-shaped seat 61 is downward. When multiple U-shaped seats 61 are used for installation, the opening directions of all U-shaped seats 61 are all downward and parallel to each other. The assembly method is to align the U-shaped seat 61 and the round seat 62 one by one and then pull down the ceiling lamp so that the round seat 62 slides into the U-shaped seat 61 to be fixed.

[0047] In summary, the ventilation cavity structure of the ceiling lamp provided in the present application includes: a ceiling lamp housing 1, including a bottom shell 11 for wall hanging and a surface shell 12 for light transmission and ventilation, the surface shell 12 is provided with an air inlet 121 and an air outlet 122; an inner support 21, fixed inside the ceiling lamp housing 1, the height of the inner support 21 being adapted to the height inside the ceiling lamp housing 1; a fan 22, mounted on one side of the inner support 21, and facing the air outlet 122. The ventilation cavity structure of the ceiling lamp of the present application uses the inner support 21 to limit the physical size of the air guide channel of the fan 22, which can ensure the air flow rate, and can also help reduce the operating noise of the fan 22, and more effectively achieve the effect of air purification.
