Description

Technical Field

[0001] The present invention relates to the field of ceiling lamps, and in particular to a ceiling lamp. Background Art

[0002] A ceiling lamp is a very common lighting tool. The ceiling lamp is a lighting fixture directly adsorbed or embedded on the ceiling of the roof. Like a chandelier, it is also the main lighting device in the room. With the improvement of people's living quality, the requirement for air quality is getting higher and higher, so there appears a ceiling lamp with air purification function.

[0003] However, the existing ceiling lamps with air purification function cannot achieve a good balance in the position distribution between air purification and the lamp body. Often, in order to ensure enough space for placing the lighting lamp, the air filtration efficiency is ignored, or both are taken into account, making the overall ceiling lamp appear thick, large and bulky. Some ceiling lamps adopt the method of side air intake and side air outlet to make the overall structure more compact, which compresses the overall space of the ceiling lamp. This method also affects the air intake efficiency and the air outlet efficiency, and at the same time, the uniformity of air intake and air outlet is also affected to a certain extent, and the overall air purification effect is average. Summary of the Invention

[0004] The purpose of the present invention is to provide a ceiling lamp. By adopting the technical solution provided by the present invention, the technical problem that the balance between the lamp body and air filtration of the existing ceiling lamp is poor, often resulting in low air filtration efficiency, is solved.

[0005] To solve the above technical problem, the present invention provides a ceiling lamp, which includes a ceiling plate, a ceiling shell, a wind guide shell, a main shell and a lamp cover fixedly connected in sequence from top to bottom;

[0006] A first accommodation cavity is formed between the ceiling shell and the wind guide shell, and a power supply component and a control main board are arranged in the first accommodation cavity;

[0007] The lamp cover covers the main shell to form a second accommodation cavity, and a light source board is arranged in the second accommodation cavity;

[0008] A fan is coaxially arranged at the axis of the wind guide shell, and a wind channel communicating with the fan is formed by inwards recessing the middle part of the lamp cover along its axis; A plurality of air holes are evenly formed along the circumferential direction of the wind guide shell;

[0009] A filter screen assembly is detachably arranged in the wind channel;

[0010] Wherein, the external air flow direction is from the filter screen assembly through the fan and then discharged from the air holes, or from the air holes into the fan and then discharged through the filter screen assembly;

[0011] In the above implementation process, the multifunctional ceiling lamp provided by the present application has both lighting function and air purification function. The filter component that plays a major purification role is arranged in the middle. With the cooperation of the fan, air can be evenly inhaled from multiple angles, purified, and then discharged. The purification coverage range is wide and uniform. The air inlet and the air outlet are arranged in layers and are interconnected through the fan, maximizing the intake and exhaust air volumes and improving the filtration efficiency. The lampshade is recessed to form an air duct, and the filter component is arranged in the air duct. No matter the air flow direction, it needs to pass through the filtering effect of the filter component to enter or exit the ceiling lamp. It can be seen that through reasonable position arrangement, the filter component and the other lighting-related parts of the ceiling lamp are orderly and compactly arranged together, enabling the lighting function and the filtration and purification function to coexist with maximum benefit, and ensuring the maximum filtration and purification effect on the premise of not overly affecting the normal lighting function.

[0012] Preferably, the ceiling shell is recessed to form a first groove for accommodating the ceiling plate; a rotation snap structure adapted to each other is circumferentially arranged on the inner peripheral wall of the first groove and the circumference of the ceiling plate, and the ceiling shell is rotationally clamped to the ceiling plate through the rotation snap structure;

[0013] In the above implementation process, the staff can fixedly install the ceiling plate on the ceiling or wall, then misalign the first clamping block and the clamping groove, insert the first groove towards the plate surface of the fixed plate, embed the plate surface of the fixed plate into the first groove, and then rotate it directionally. The rotation snap structure completes the fixed connection during the rotation process.

[0014] Preferably, an electrical clamping structure is provided on the ceiling shell and the ceiling plate; the electrical clamping structure includes a first clamping block extending with a plurality of arc-shaped clamping edges, and a clamping groove cooperating with the clamping edges, and conductive parts adapted to each other are provided on the clamping edges and the clamping groove;

[0015] Among them, after the rotation snap structure is snapped in place, the clamping edges are snapped into the clamping groove and the electrical connection between the ceiling plate and the fixed plate is completed;

[0016] In the above implementation process, the rotation snap structure completes the fixed connection during the rotation process. At the same time, the clamping edges on the first clamping block are also snapped into the clamping groove during the rotation process, and the conductive parts on the clamping edges come into contact with the conductive parts in the clamping groove to complete the electrical connection;

[0017] In this solution, the fixing of the ceiling lamp is completed by the rotation snap method, and at the same time, its electrical conduction is also completed. There is no need to additionally connect other wires. The installation and use are convenient and fast, and the subsequent disassembly and replacement are also very convenient, improving the user experience. In addition, the rotation snap structure is arranged on the outer periphery, and the electrical clamping structure is arranged on the inner periphery. The two cooperate with each other to make the overall connection structure more stable and firm, the stress points are evenly distributed, and the safety performance after connection is higher.

[0018] Preferably, a second groove is formed around the first groove on the side of the ceiling shell facing away from the ceiling plate; the second groove is annular, and the power supply assembly and the control main board are arranged in the second groove.

[0019] In the above implementation process, the present solution makes full use of the internal space of the ceiling lamp. A first groove is formed to accommodate the ceiling plate, so that the ceiling lamp can be attached to the wall during installation. The shape of the first groove will generate another groove, which is the second groove. The present application installs parts such as the power supply assembly and the control main board in the second groove, effectively utilizing this part of the space, making the internal parts of the ceiling lamp more compactly arranged and the overall more compact.

[0020] Preferably, the air guide shell covers the fan; a plurality of air guide plate assemblies are evenly formed around the inner peripheral wall of the air guide shell towards its axis; the gaps between the plurality of air guide plate assemblies communicate with the air holes.

[0021] In the above implementation process, the air guide plate assemblies can conduct the air flow smoothly. Whether the air enters or exits from the air guide plates, it can achieve uniform input or output of the air flow, thereby reducing the noise generated during air flow and having a better filtering effect.

[0022] Preferably, the air guide plate assembly includes a first air guide plate and a second air guide plate; the extension length of the first air guide plate is greater than that of the second air guide plate, and a plurality of first air guide plates are arranged at equal intervals; the second air guide plate is arranged between two adjacent first air guide plates.

[0023] In the above implementation process, the first air guide plate conducts a large diversion of the air flow, and then a uniform diversion is carried out again from a plurality of second air guide plates to achieve uniform air intake or uniform air outlet.

[0024] Preferably, the first air guide plate is axially parallel to the air guide shell and is formed with a through hole communicating with the second accommodation cavity.

[0025] In the above implementation process, in order to achieve high-efficiency air intake and air outlet and improve the filtering efficiency, there is a certain interval between the air outlet and the air inlet; the light source board is separated from the power supply assembly and the control main board by the fan, and the through hole on the first air guide plate can allow the connecting wire to pass through, enabling electrical connection between the light source board, the power supply assembly and the control main board. With this structure, electrical connection between separated parts is achieved while ensuring sufficient airtightness, and it also implements the technical effect of balanced and efficient structural compactness, lighting function and air purification function through reasonable and ingenious arrangement of part positions in the present application.

[0026] Preferably, the filter assembly includes a filter frame in a cylindrical shape with a receiving groove formed therein, and a filter mounted on the inner bottom surface of the filter frame; the outer wall of the upper edge of the filter frame is threadedly connected to the inner wall of the through groove.

[0027] Preferably, the filter assembly further includes a baffle disposed below the filter frame, and a connecting rod connecting the baffle and the bottom surface of the filter frame;

[0028] In the above implementation process, the design of the baffle can, on the one hand, block the filter frame, which promotes the overall aesthetics; on the other hand, it effectively limits the size of the air outlet, making the airflow more orderly when passing through; for example, when the air enters the ceiling lamp from the air duct, the external air needs to enter from the edge between the baffle and the air duct inlet, effectively controlling the air intake volume and the air intake direction. When the air is discharged from the air duct towards the baffle, the baffle plays a role in diverting, evenly dispersing the filtered air everywhere.

[0029] Preferably, the lamp shade and the main housing form a first component, and the filter assembly and the air guide housing form a second component; the first component is detachably disposed on the second component;

[0030] In the above implementation process, the lamp shade and the main housing are combined into a first component, which is the main body of the lamp, while the air guide housing and the filter assembly are combined into a second component to form the purification main body; in specific use, users can replace different lamp main bodies and purification main bodies according to their own preferences, so as to achieve diversified combinations; when the lamp main body fails, the lamp main body can also be disassembled separately for maintenance without disassembling the entire ceiling lamp, further improving the flexibility and diversity of use.

[0031] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0032] (1) By cleverly arranging the positional relationship between the filter assembly and the lamp body, as well as the positional relationship between the air duct, the fan, and the air holes, the present application achieves a good balance between the lighting function and the air purification function of the ceiling lamp, enabling the coexistence of the lighting function and the filtration and purification function with the maximum benefit. On the premise of not overly affecting the normal lighting function, the maximum filtration and purification effect is ensured;

[0033] (2) Making full use of the internal space to achieve a compact overall structure; technical improvements such as placing the power supply assembly and the control main board in the second groove body and forming through holes on the first air guide plate for the conductive wires to pass through are all through reasonable and clever arrangements of the positions of the parts to achieve the technical effects of a compact structure, balanced and efficient lighting function and air purification function;

[0034] (3) Improvement in purification performance; the air outlet and air inlet are arranged in layers. Compared with the technical solution of side air inlet and side air outlet, the air inlet and air outlet processes in this solution have less mutual influence, the air flow transportation is more stable, thus improving the purification efficiency;

[0057] Embodiment

[0058] The existing ceiling lamps with air purification functions cannot achieve a good balance in the position distribution between air purification and the lamp body. Often, in order to ensure enough space for the placement of the lighting lamp, the air filtration efficiency is ignored, or when both are taken into account, the overall ceiling lamp appears thick, large and heavy; some ceiling lamps use the method of side air intake and side air outlet to make the overall structure of the ceiling lamp more compact, which compresses the overall space of the ceiling lamp. However, this method also affects the air intake efficiency and the air outlet efficiency, and at the same time, the uniformity of air intake and air outlet is also affected to a certain extent, and the overall air purification effect is average. To solve this technical problem, the following technical solutions are provided in this embodiment:

[0059] Specifically, please refer to Figure 1-14 , this embodiment provides a ceiling lamp, which includes a ceiling plate 10, a ceiling shell 20, a wind guide shell 30, a main shell 40 and a lamp shade 50 that are fixedly connected in sequence from top to bottom;

[0060] Specifically, a first accommodation cavity is formed between the ceiling shell 20 and the wind guide shell 30, and a power supply component 21 and a control main board 22 are arranged in the first accommodation cavity;

[0061] Specifically, the lamp shade 50 covers the main shell 40 to form a second accommodation cavity, and a light source board 41 is arranged in the second accommodation cavity;

[0062] A fan 70 is coaxially arranged at the axis of the wind guide shell 30, and a wind channel communicating with the fan 70 is formed by inwards recessing the middle part of the lamp shade 50 along its axis; a plurality of air holes 31 are uniformly formed along the circumferential direction of the wind guide shell 30;

[0063] A filter screen assembly 60 is detachably arranged in the wind channel;

[0064] Among them, the external air flow direction is discharged from the air holes 31 after passing through the filter assembly 60 by the fan 70, or enters from the air holes 31, passes through the fan 70, and then is discharged through the filter assembly 60;

[0065] Please refer to Figure 5-6 , when the air flow of the external air enters the ceiling lamp, it can have two ways. Please refer to Figure 5 , under the guiding action of the fan 70, the external air flow is introduced by the air duct, reaches the fan 70 through the filter assembly 60, and the fan 70 discharges the air flow out of the lamp along the air guiding shell 30, so as to realize air intake from below and air outlet from the upper side wall; Figure 6 Then it is exactly opposite to Figure 5 the air flow direction in

[0066] In the above solution, the multifunctional ceiling lamp provided by the present application has both a lighting function and an air purification function. The filter assembly 60 that plays a major purification role is arranged in the middle. With the cooperation of the fan 70, air can be evenly inhaled from multiple angles, purified and then discharged. The purification coverage range is wide and uniform; the air inlet and the air outlet are arranged in layers and are interconnected through the fan 70, which maximally ensures the air intake and air outlet volume and improves the filtration efficiency; the lampshade 50 is recessed to form an air duct, and the filter assembly 60 is arranged in the air duct. No matter what the air flow direction is, it needs to pass through the filtering action of the filter assembly 60 to enter the ceiling lamp or be discharged out of the lamp. It can be seen that the present application arranges the filter assembly 60 and the other lighting-related parts of the ceiling lamp in an orderly and compact manner through reasonable position arrangements, enabling the lighting function and the filtration and purification function to coexist with the maximum benefit, and ensuring the maximum filtration and purification effect on the premise of not excessively affecting the normal lighting function.

[0067] Specifically, a first groove 15 for accommodating the ceiling plate 10 is formed by the recess of the ceiling shell 20; a rotation snap structure 11 adapted to each other is circumferentially arranged on the inner peripheral wall of the first groove 15 and the circumference of the ceiling plate 10, and the ceiling shell 20 is rotationally clamped to the ceiling plate 10 through the rotation snap structure 11;

The rotation snap structure 11 completes the fixed connection during the rotation process.

[0069] Specifically, an electrical clamping structure is provided on the ceiling shell 20 and the ceiling plate 10; the electrical clamping structure includes a first clamping block 12 extending with a plurality of arc-shaped clamping edges 121, and a clamping groove 13 cooperating with the clamping edges 121, and conductive parts adapted to each other are provided on the clamping edges 121 and the clamping groove 13;

[0070] Among them, after the rotary snap structure 11 is snapped in place, the card edge 121 snaps into the card slot 13 and completes the electrical connection between the ceiling suction disc 10 and the fixed disc;

[0071] In the above solution, the rotary snap structure 11 completes the fixed connection during the rotation process. At the same time, the card edge 121 on the first card block 12 also snaps into the card slot 13 during the rotation process, and the conductive parts on the card edge 121 come into contact with the conductive parts in the card slot 13 to complete the electrical connection;

[0072] In this solution, the rotation snap method not only completes the fixation of the ceiling lamp but also its electrical conduction, eliminating the need to dock other wires additionally. It is convenient and fast to install and use, and it is also very convenient to disassemble and replace later, enhancing the user experience; in addition, the rotary snap structure 11 is provided on the outer periphery, while the electrical snap structure is provided on the inner periphery. The two cooperate with each other to make the overall connection structure more stable and firm, with the stress points evenly distributed and higher safety performance after connection.

[0073] Specifically, on the side of the ceiling suction shell 20 facing away from the ceiling suction disc 10, a second groove body is formed around the first groove body 15; the second groove body is annular, and the power supply assembly 21 and the control main board 22 are arranged in the second groove body;

[0074] In the above solution, this solution makes full use of the internal space of the ceiling lamp. In order to accommodate the ceiling suction disc 10, the first groove body 15 is formed, enabling the ceiling lamp to fit against the wall during installation. The shape of the first groove body 15 will generate another groove, which is the second groove body. In this application, parts such as the power supply assembly 21 and the control main board 22 are installed in the second groove body, effectively utilizing this part of the space, making the internal parts of the ceiling lamp more compactly arranged and the overall more compact.

[0075] Specifically, a number of fixing through holes 14 are formed through the ceiling suction disc 10;

[0076] In the above solution, the staff fixes the fixed disc to the wall through the fixing screws or other fastening devices passing through the fixing through holes 14;

[0077] Specifically, a wiring terminal 131 is provided on the side of the ceiling suction disc 10 facing away from the ceiling suction shell 20. The wiring terminal 131 is electrically connected to the electrical snap structure provided on the ceiling suction disc 10; the wiring terminal 131 is externally connected to a conducting wire, and only one connection is required during installation. There is no need to connect the wire again when the ceiling lamp is installed later, improving the efficiency.

[0078] Furthermore, the wiring terminal 131 includes a neutral wire terminal, a live wire terminal, and a ground wire terminal;

[0079] Specifically, the air guide housing 30 covers the fan 70; a plurality of air guide plate assemblies 32 are evenly formed around the inner peripheral wall of the air guide housing 30 towards its axis; the gaps between the plurality of air guide plate assemblies 32 communicate with the air holes 31;

[0080] In the above solution, the air guide plate assembly 32 can conduct the air flow smoothly. Whether the air enters or exits from the air guide plate, it can achieve uniform input or output of the air flow, thereby reducing the noise generated during air flow and having a better filtering effect.

[0081] Specifically, the air guide plate assembly 32 includes a first air guide plate 321 and a second air guide plate 322; the extension length of the first air guide plate 321 is greater than that of the second air guide plate 322, and a plurality of first air guide plates 321 are arranged at equal intervals; the second air guide plate 322 is disposed between two adjacent first air guide plates 321;

[0082] In the above solution, the first air guide plate 321 conducts a large diversion of the air flow, and then a uniform diversion effect is carried out again on a plurality of second air guide plates, so as to achieve uniform air inlet or uniform air outlet;

[0083] Specifically, the first air guide plate 321 is axially parallel to the air guide housing 30 and is formed with a through hole 3211 communicating with the second accommodation cavity;

[0084] In the above solution, in order to achieve high-efficiency air inlet and outlet and improve the filtering efficiency, there is a certain interval between the air outlet and the air inlet; the light source board 41 is separated from the power supply assembly 21 and the control main board 22 by the fan 70, and the through hole 3211 on the first air guide plate 321 can allow the connection wire to pass through, so that the light source board 41, the power supply assembly 21 and the control main board 22 can be electrically connected. With this structure, while ensuring sufficient airtightness, the electrical connection between the separated parts is achieved, and the technical effect of compact structure, balanced and efficient lighting function and air purification function is also implemented through the reasonable and ingenious arrangement of the positions of the parts in this application.

[0085] Specifically, the filter assembly 60 includes a filter frame 61 in a cylindrical shape and formed with a receiving groove, and a filter installed on the inner bottom surface of the filter frame 61; the outer side wall of the upper edge of the filter frame 61 is threadedly connected 62 to the inner wall of the through groove;

[0086] Specifically, a plurality of ventilation holes 611 are formed at the bottom of the filter frame 61; the ventilation holes 611 at the bottom of the filter frame 61 can allow the air flow to pass through, and the overall structure in the form of a bracket can be used to place filter accessories such as filters.

[0087] Specifically, the filter assembly 60 further includes a baffle 63 disposed below the filter frame 61, and a connecting rod 64 connecting the baffle 63 and the bottom surface of the filter frame 61;

[0088] In the above solution, the design of the baffle 63 can, on the one hand, block the filter screen holder 61, which promotes the overall aesthetics; on the other hand, it effectively limits the size of the air outlet, making the airflow more orderly when passing through. For example, when the air enters the ceiling lamp from the air duct, the external air needs to enter from the edge between the baffle 63 and the air duct inlet, effectively controlling the air intake volume and the air intake flow direction. When the air is discharged from the air duct towards the baffle 63, the baffle 63 plays a role in splitting the flow, evenly dispersing the filtered air everywhere.

[0089] Specifically, a second lamp body 42 is provided between the fan 70 and the filter screen assembly 60;

[0090] Furthermore, an antibacterial coating is applied to the filter screen;

[0091] Furthermore, the antibacterial coating includes titanium dioxide and nano silver;

[0092] Furthermore, the second lamp body 42 is a UV lamp or a common lighting lamp;

[0093] In the above solution, under the illumination of the light emitted by the lamp body, titanium dioxide, as a photocatalyst reactant, produces a strong catalytic degradation function, effectively degrading toxic and harmful gases in the air, decomposing and rendering harmless the toxins released by bacteria or fungi. At the same time, it also has functions such as deodorization, anti-fouling, and air purification; while nano silver has a broad-spectrum antibacterial function and can effectively inhibit most bacteria.

[0094] Specifically, please refer to Figure 15 , the lamp cover 50 and the main housing 40 form a first component, and the filter screen assembly 60 and the air guide housing 30 form a second component; the first component is detachably arranged on the second component;

[0095] In the above solution, the lamp cover 50 and the main housing 40 are combined into a first component, which is the main body of the lamp, while the air guide housing 30 and the filter screen assembly 60 are combined into a second component to form the purification main body; in specific use, users can replace different lamp main bodies and purification main bodies according to their own preferences, so as to achieve diversified combinations; when the lamp main body fails, the lamp main body can also be detached and repaired separately without disassembling the entire ceiling lamp, further improving the flexibility and diversity of use;

[0096] Furthermore, during specific disassembly, first loosen and disassemble the filter screen assembly 60, and then split the first component from the bottom end of the air guide housing 30, so that the separation of the first component, that is, the lamp main body, can be achieved;

[0097] Furthermore, a connection socket and fastening screws can be provided between the top surface of the first component and the bottom surface of the air guide housing 30 to achieve fixed connection and electrical connection.

[0098] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other. The above description is only for the preferred embodiments of the present invention, and does not impose any formal limitation on the present invention.
