[0002] With social development and increased attention to living environment, more and more families are choosing to install air purifying lamps that integrate lighting and air purification functions to improve indoor air quality and create a healthy and comfortable home and work environment. However, after researching existing air purifying lamps, the inventors found that the air inlet and outlet of existing ceiling-mounted air purifying lamps are positioned vertically, which has the following problems: 1. Because both the air inlet and outlet need to be located on the lower side of the ceiling, existing air purifying lamps can only be surface-mounted on the ceiling (it is difficult to install them in a concealed manner); 2. Because the air inlet of existing air purifying lamps faces upwards, debris (such as dust) on the ceiling easily accumulates at the air inlet and can easily enter and contaminate the interior of the air purifying lamp through the air inlet.

They are only for the convenience of describing this utility model 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 utility model.

[0032] In this utility model, unless otherwise explicitly defined, the terms "setting," "installing," and "connecting" should be interpreted broadly. For example, they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to a fixed connection, a detachable connection, or an integral molding; they can refer to a mechanical connection; they can refer to the internal connection of two components or the interaction between two components. Those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0033] Reference Figures 1 to 5 This utility model provides an air purifying lamp, which includes a housing assembly 100, a light-emitting module 200, a fan module 300, and a purification module 400.

[0034] The housing assembly 100 is provided with an air duct S. The air inlet 121 and air outlet 122 of the air duct S are both located at the bottom of the housing assembly 100 and face downwards. The housing assembly 100 can pass through pre-installed holes in the ceiling so that the air inlet 121 and air outlet 122 are both located on the lower side of the ceiling. A light-emitting module 200 is located at the bottom of the housing assembly 100 and emits light downwards to illuminate the space below the ceiling. A fan module 300 is located in the air duct S and operates to allow air entering through the air inlet 121 to pass through the air duct S and exit through the air outlet 122. A purification module 400 is located in the housing assembly 100 and purifies the air within the air duct S. The light-emitting module 200 can be configured as a lamp panel with LED beads; the fan module 300 can be configured as a fan blade assembly.

[0035] It is understood that in this embodiment, the purification module 400 is a water ion generator. The purification module 400 can electrolyze the water in the air inside the air duct S to generate ions with strong oxidizing and reducing effects. These ions can remove bacteria, viruses, and harmful substances from the air inside the air duct S, thereby purifying the air inside the air duct S. Of course, in some embodiments, the purification module 400 is a negative ion generator.

[0036] Understandably, the shell assembly 100 can also be surface-mounted on the ceiling, including ceiling mounting and hanging mounting.

[0037] With the above structure, on the one hand, by placing the downward-facing air inlet 121 and air outlet 122 at the bottom of the housing assembly 100, and in conjunction with the structural design of the housing assembly 100 passing through the pre-installed hole in the ceiling, the air purifying lamp can be mostly installed on the upper side of the ceiling (only the bottom light-emitting module 200 and the air outlet structure are exposed), achieving a concealed installation effect. Therefore, the air purifying lamp of this application can be concealed in the ceiling to maintain the integrity of the ceiling plane and improve the aesthetics of the indoor space. On the other hand, the innovative downward-facing air inlet 121 avoids the traditional top-mounted air inlet 121. The air purifier is susceptible to dust accumulation on the ceiling and its gravity self-cleaning effect significantly reduces the probability of debris entering the air purifier through the air inlet 121, thus effectively extending the maintenance and cleaning cycle of the air purifier. Furthermore, the air duct structure of this application, combined with the design of the purification module 400, enables an air purification circulation path, specifically: 1. Downward airflow pushes pollutants upward; 2. Efficient intake through the bottom air inlet 121; 3. Deep sterilization by ions within the air duct; 4. A closed-loop purification path of secondary downward sinking of clean air. Therefore, the air purifier of this application can significantly improve the air purification efficiency of the space.

[0038] In this embodiment, refer to Figure 1 and Figure 2 Both the air inlet 121 and the air outlet 122 are annular structures, with the air inlet 121 and the air outlet 122 arranged inside and outside the annular structure. The light-emitting module 200 is located inside the air inlet 121. The number of air inlets 121 and air outlets 122 is set to one.

[0039] It is understood that in this embodiment, the light-emitting module 200 is located above the air inlet 121, and the light-emitting module 200 is disposed inside the air inlet 121, that is, the top view projection of the light-emitting module 200 falls inside the top view projection of the air inlet 121. In some embodiments, the light-emitting module 200 may be located on the same horizontal plane as the air inlet 121, and the light-emitting module 200 may be disposed inside the air inlet 121.

[0040] With the above structure, on the one hand, when the outer annular air outlet 122 sprays clean air downwards at high speed, it can stimulate the inner annular air inlet 121 to form a strong negative pressure zone, thereby improving the efficiency of polluted air intake; on the other hand, the air inlet 121 and air outlet 122, which are both annular in structure, are arranged inside and outside, and the light-emitting module 200 is located inside the air inlet 121, which can achieve the effect of windless central lighting and strong purification airflow in the surrounding area; furthermore, the light-emitting module 200 is located inside the air inlet 121, so that the air duct structure of this application can also serve as a heat dissipation air duct, ensuring the working stability of the light-emitting module 200.

[0041] In some embodiments, the number of air inlets 121 is set to two, and the two air inlets 121 are arranged sequentially from the inside to the outside.

[0042] In some embodiments, the number of air outlets 122 is set to two, and the two air outlets 122 are arranged sequentially from the inside to the outside.

[0043] In some embodiments, the light-emitting module 200 is disposed between the annular air inlet 121 and the annular air outlet 122.

[0044] In some embodiments, the light-emitting module 200 is disposed on the outside of the annular air outlet 122.

[0045] It is understandable that the airflow process of the air purifying lamp in this application during operation is as follows: Figure 2 As indicated by the dashed arrow.

[0046] The shell assembly 100 includes a top shell 110, a bottom cover 120, and a partition cylinder 130.

[0047] Reference Figures 2 to 5 The top shell 110 has a first cavity 111 with its opening facing downwards. The purification module 400 is disposed in the top shell 110. The bottom cover 120 is disposed at the bottom of the top shell 110 and covers the opening of the first cavity 111. The bottom cover 120 has the aforementioned air inlet 121 and air outlet 122. The bottom cover 120 has a second cavity 123 located inside the air inlet 121 with its opening facing downwards. The light-emitting module 200 is disposed in the second cavity 123 and can emit light towards the opening of the second cavity 123. The top shell 110 can pass through a pre-installed hole in the ceiling so that both the air inlet 121 and the air outlet 122 are located on the lower side of the ceiling. The top of the partition cylinder 130 and Each part has a port 131 at the bottom that communicates with its inner cavity. The bottom of the partition cylinder 130 is located on the bottom cover 120. The partition cylinder 130 is located in the first cavity 111 through the opening of the first cavity 111. The port 131 at the bottom, the inner cavity of the partition cylinder 130, the port 131 at the top, the first space S1 between the top of the partition cylinder 130 and the bottom wall of the first cavity 111, and the second space S2 between the outer side of the partition cylinder 130 and the side wall of the first cavity 111 are connected in sequence to form the above-mentioned air duct S. The air inlet 121 is connected to the port 131 at the bottom, and the air outlet 122 is connected to the second space S2. The fan module 300 is located in the first space S1.

[0048] In some embodiments, the fan module 300 is disposed within the cavity of the partition cylinder 130.

[0049] In some embodiments, the light-emitting module 200 is disposed on the top shell 110.

[0050] In some embodiments, the purification module 400 is disposed on the bottom cover 120.

[0051] In some embodiments, the purification module 400 is disposed on the partition cylinder 130 and located in the inner cavity of the device.

[0052] The purification module 400 is located on the top shell 110. For details, please refer to [reference needed]. Figure 2 , Figure 3 as well as Figure 5 The top shell 110 is provided with a third cavity 112 and a through hole 113. The third cavity 112 and the first cavity 111 are arranged vertically. The through hole 113 connects the third cavity 112 and the first space S1. The purification module 400 is located in the third cavity 112. The purification module 400 can electrolyze the water in the air in the air duct S through the through hole 113.

[0053] In some embodiments, the third cavity 112 and the first cavity 111 are arranged on the left and right sides, and the through hole 113 connects the third cavity 112 and the second space S2.

[0054] In this embodiment, the outer side of the top shell 110 is provided with three spring fasteners. When the top shell 110 passes through the pre-installed hole in the ceiling, the spring fasteners can abut against the upper side of the ceiling to prevent the top shell 110 from disengaging downward from the pre-installed hole.

[0055] It is understandable that the spring fastener is the same as the spring fastener on existing downlights. The principle of mounting the air purifier lamp on the ceiling is the same as the principle of mounting the downlight on the ceiling, so it will not be described again here.

[0056] In some embodiments, the spring fasteners may be two, four, or the like.

[0057] In this embodiment, refer to Figures 1 to 5 The top shell 110 is provided with an abutment platform 114 on its outer side. When the top shell 110 passes through the pre-installed hole in the ceiling, the abutment platform 114 can abut against the lower side of the ceiling to clamp the ceiling together with the spring fastener.

[0058] With the above structure, on the one hand, the abutment platform 114 and the spring fastener together clamp the ceiling, which can improve the stability of the air purifying lamp when it is installed on the ceiling; on the other hand, the abutment platform 114 can cover the gap between the hole wall of the pre-installed hole and the outer side of the top shell 110, which can optimize the appearance of the air purifying lamp after it is installed on the ceiling.

[0059] In this embodiment, refer to Figure 1 and Figure 2The bottom cover 120 is connected to a light-transmitting cover 500 located at the opening of the second cavity 123. The light-emitting module 200 can emit light towards the opening of the second cavity 123, so that the light passes through the light-transmitting cover 500 and is emitted downward. The light-transmitting cover 500 can block external debris from entering the second cavity 123 through the opening of the second cavity 123, so as to provide a certain protection for the light-emitting module 200.

[0060] Understandably, the light-transmitting cover 500 can be designed as a lens cover with optical effects according to requirements.

[0061] In this embodiment, refer to Figure 4 and Figure 5 The top shell 110, the partition cylinder 130, the light-emitting module 200, and the light-transmitting cover 500 are all detachably connected to the bottom cover 120 via a snap-fit ​​structure.

[0062] With the above structure, the top shell 110, the partition cylinder 130, the light-emitting module 200, and the light-transmitting cover 500 are all detachably connected to the bottom cover 120 through a snap-fit ​​structure, which can greatly reduce the use of bolts and fasteners, thereby reducing connection costs and connection difficulty, and making it easier for manufacturers to install the top shell 110, the partition cylinder 130, the light-emitting module 200, and the light-transmitting cover 500 onto the bottom cover 120.

[0063] Of course, this utility model is not limited to the above-described embodiments.
