Description

Technical Field

[0001] This utility model relates to the technical field of range hoods, specifically to a germicidal lamp assembly and a range hood. Background Technology

[0002] As consumers' demand for kitchen hygiene and safety increases, ultraviolet sterilization technology is gradually being applied to the range hood industry.

[0003] Currently, ultraviolet lamps are typically installed at the air inlet of range hoods to disinfect and sterilize cooking fumes. Specifically, ultraviolet beams irradiate the fumes to decompose and kill microorganisms within them, thereby eliminating bacteria and odors from the range hood.

[0004] However, the cooking fumes are not fully exposed to the ultraviolet light beams before entering the fan, and the short irradiation time easily leads to poor disinfection effects. Furthermore, oil particles in the fumes easily condense on the surface of the ultraviolet lamp tube, forming a light-blocking film, which reduces its disinfection and sterilization performance. Although the ultraviolet lamp tubes can be disassembled and cleaned periodically, frequent disassembly and cleaning are not only cumbersome and time-consuming, but also greatly affect the service life of the ultraviolet lamp tubes. Utility Model Content

[0005] In order to at least partially solve the problems existing in the prior art, according to one aspect of the present invention, a germicidal lamp assembly is provided, the technical solution of which is as follows.

[0006] A germicidal lamp assembly includes a lampshade, a light-emitting element, and a heating structure. The lampshade encloses a light cavity with an opening. The light-emitting element is at least partially disposed within the light cavity, and the light emitted by the light-emitting element is partly directed toward the cavity wall and partly toward the opening. The heating structure is constructed as a heating element, which is disposed on the cavity wall and heats up by absorbing the light emitted onto the cavity wall; or, the cavity wall of the light cavity is made of a self-heating material to form the heating structure.

[0007] This invention relates to a germicidal lamp assembly. A light-emitting element within the light cavity emits light through an opening to irradiate cooking fumes, thereby disinfecting and sterilizing them. Furthermore, a heating element can be attached to the side wall of the cavity. This heating element absorbs the light emitted by the light-emitting element. Alternatively, the side wall of the cavity can be made of a self-heating material to increase its own temperature. Under this high temperature, the condensed oil particles on the cavity wall surface melt and drip off, eliminating the need for frequent disassembly and cleaning of the germicidal lamp assembly. This automatic cleaning effectively improves the sterilization efficiency and lifespan of the germicidal lamp assembly.

[0008] For example, a lens is provided at the opening, and light rays heading towards the opening are refracted into parallel rays by the lens and emitted. In this way, when the light emitted by the light-emitting element passes through the lens, the light rays entering the lens from different angles can be refracted into parallel rays, thereby concentrating the illumination of a certain area and improving the sterilization effect and efficiency of the germicidal lamp assembly.

[0009] For example, the lamp cover has a base and a cover body. The cover body has a first end and a second end. The first end is connected to the base body, and an opening is formed at the second end. A light-emitting element is disposed on the base body, and a heat-generating element is disposed on the cover body. Alternatively, the cover body may be at least partially made of a self-heating material. In this way, the light-emitting element and the heat-generating element can be disposed at different positions on the lamp cover, effectively improving the layout rationality of the germicidal lamp assembly. Furthermore, the fact that at least part of the cover body can be made of a self-heating material effectively simplifies the connection structure of the germicidal lamp assembly and reduces the manufacturing difficulty and cost of the germicidal lamp assembly.

[0010] For example, the housing includes a first part and a second part connected together. The first part is closer to the base than the second part. A positioning part is formed at the connection between the first part and the second part, and the lens is fixed by the positioning part. In this way, the lens can be positioned at the opening of the optical cavity through the positioning part, so that the lens can be easily and quickly disassembled and assembled when cleaning or replacing the lens, effectively simplifying the connection between the lens and the housing and improving the convenience of lens assembly.

[0011] For example, at least a portion of the outer wall of the enclosure is provided with a heating element, and at least a portion of the heating element is located on the outer wall of the first part. The portion of the enclosure corresponding to the heating element forms a light-transmitting surface, and the remaining portion forms a light-shielding surface; or, at least a portion of the enclosure is made of a self-heating material, and at least a portion of the enclosure made of a self-heating material is located in the first part. In this way, the light-transmitting surface allows the light emitted by the light-emitting element to directly irradiate the heating element, thereby causing the heating element to absorb the light and generate heat. The light-shielding surface can concentrate the light scattered through the opening, avoiding insufficient light intensity due to an excessively large light dissipation range, thus preventing a poor sterilization effect of the germicidal lamp assembly and effectively improving the practicality and sterilization effect of the germicidal lamp assembly. Furthermore, the enclosure made of a self-heating material being located in the first part greatly slows down the rate of heat loss from the enclosure, effectively improving the self-cleaning effect of the germicidal lamp assembly.

[0012] For example, the cover gradually increases in size from the first end to the second end, forming a trumpet shape. In this way, the trumpet-shaped cover allows molten oil to drip off the cover and the base under the action of gravity, avoiding oil residue on the cover and the base, realizing automated cleaning of the germicidal lamp assembly, and effectively improving the practicality and convenience of using the germicidal lamp assembly.

[0013] For example, the lens has a convex surface facing the base. In this way, the light emitted by the light-emitting element on the base can enter the lens through the convex surface of the lens. The lens can refract and focus light rays entering from different angles into a smaller area, thereby effectively improving the light intensity of the light-emitting element and the sterilization efficiency.

[0014] For example, there are one or more light-emitting elements, which are arranged in rows and columns at intervals. In this way, the multiple light-emitting elements arranged in rows and columns can not only significantly improve the light intensity of the germicidal lamp assembly, but also allow the germicidal lamp assembly to cover a larger irradiation area, thereby further improving the practicality of the germicidal lamp assembly.

[0015] According to one aspect of this utility model, a range hood is also provided, including a housing and the germicidal lamp assembly as described above. The germicidal lamp assembly is disposed inside the housing, and a fan is disposed inside the housing with its opening facing the fan. Since the germicidal lamp assembly as described above has the aforementioned beneficial effects, the range hood including the germicidal lamp assembly as described above also has the aforementioned beneficial effects, which will not be elaborated further here.

[0016] For example, the casing has a rear panel, on which the germicidal lamp assembly is mounted. This allows the opening of the germicidal lamp assembly's light cavity to face the fan and the airflow path created by the fan's rotation, effectively ensuring the rationality of the range hood's structural layout.

[0017] For example, an airflow path is formed inside the casing via a fan, and light rays emitted from the opening pass through the airflow path and hit the fan. In this way, the germicidal lamp assembly can sterilize the oil fumes and the fan simultaneously, which not only improves the sterilization efficiency of the germicidal lamp assembly, but also greatly reduces the frequency of fan cleaning and maintenance, effectively reducing cleaning and maintenance costs and extending the service life of the fan.

[0018] For example, the lampshade forms a light-emitting surface at the opening, and the light-emitting surface is inclined to the rear panel of the enclosure, so that the light emitted from the light-emitting surface shines obliquely upward toward the fan. In this way, the light emitted by the germicidal lamp assembly can shine obliquely upward to form a larger contact area with the airflow path, thereby further improving the sterilization effect of the germicidal lamp assembly, and thus improving the effect of the range hood in treating oil fumes.

[0019] For example, the germicidal lamp assembly is detachably connected to the chassis. This allows for easy disassembly and assembly of the germicidal lamp assembly when maintenance or replacement is required, significantly reducing maintenance costs and assembly / disassembly difficulties, and improving user convenience.

Detailed Implementation

[0035] In the following description, numerous details are provided to enable a thorough understanding of the present invention. However, those skilled in the art will appreciate that the following description merely illustrates preferred embodiments of the present invention, which may be practiced without one or more of these details. Furthermore, to avoid confusion with the present invention, some technical features well-known in the art have not been described in detail.

[0036] To fully understand the embodiments of this utility model, a detailed structure will be presented in the following description. Obviously, the implementation of the embodiments of this utility model is not limited to the specific details familiar to those skilled in the art. Preferred embodiments of this utility model are described in detail below; however, in addition to these detailed descriptions, this utility model may have other embodiments.

[0037] One embodiment of this utility model provides a germicidal lamp assembly 1, which can melt the oil particles condensed on the surface of the lamp cover 11, thereby eliminating the need for frequent disassembly and cleaning of the germicidal lamp assembly 1 and achieving automatic cleaning of the germicidal lamp assembly 1. The following will describe in detail a germicidal lamp assembly 1 according to an embodiment of this utility model with reference to the accompanying drawings.

[0038] like Figures 1 to 3As shown, the germicidal lamp assembly 1 includes a lampshade 11, a light-emitting element 12, and a heating structure. The lampshade 11 encloses a light cavity 111 with an opening. The light-emitting element 12 is at least partially disposed within the light cavity 111, and the light emitted by the light-emitting element 12 is directed partly toward the cavity wall 1111 of the light cavity 111 and partly toward the opening. The heating structure is constructed as a heating element 13, which is disposed on the cavity wall 1111 and heats up by absorbing the light emitted onto the cavity wall 1111. Alternatively, the cavity wall 1111 of the light cavity 111 is made of a self-heating material to form the heating structure.

[0039] Specifically, the light-emitting element 12 can emit light outwards. When the germicidal lamp assembly 1 is applied to the range hood 2, part of the light can directly irradiate the cooking fumes through the opening of the light cavity 111 to sterilize the microorganisms in the fumes. Another part of the light can irradiate the cavity wall 1111, and the heating element 13 located on the cavity wall 1111 can absorb the light and generate heat, thereby increasing the temperature inside the light cavity 111. When the temperature rises to a certain level, the oil stains adhering to the lamp cover 11 and the light-emitting element 12 can be melted, thus ensuring the efficient operation of the germicidal lamp assembly 1. Of course, the cavity wall 1111 of the light cavity 111 can also be made of a self-heating material so that it can generate heat when irradiated by light.

[0040] Specifically, the light-emitting element 12 can be an ultraviolet lamp, and the ultraviolet light emitted by the ultraviolet lamp can quickly kill microorganisms in the oil fumes. The heating element 13 can be made of graphene composite material. Graphene composite material not only has high temperature resistance, but also has high ultraviolet light absorption efficiency, thereby improving the heating efficiency of the heating element 13.

[0041] Specifically, when the cavity wall 1111 of the optical cavity 111 is made of a self-heating material, the self-heating material can be graphene, black anodized aluminum, black ceramic coating, black polycarbonate or black thermoplastic polyurethane, etc., and this application does not make specific limitations on this.

[0042] The light-emitting element 12 can be detachably disposed in the light cavity 111. Specifically, the light-emitting element 12 can be fixed in the light cavity 111 of the lamp cover 11 by means of snap-fit ​​connection or threaded connection. This application does not make specific limitations on the fixing method of the light-emitting element 12. Any method that can firmly fix the light-emitting element 12 in the light cavity 111 is acceptable.

[0043] The germicidal lamp assembly 1 of this invention has a light-emitting element 12 located in the light cavity 111 that emits light outward through an opening to irradiate oil fumes, thereby disinfecting and sterilizing the oil fumes. Furthermore, a heating element 13 can be attached to the side wall of the cavity 1111. The heating element 13 can absorb the light emitted by the light-emitting element 12, or the side wall of the cavity 1111 can be made of a self-heating material to increase its own temperature. Under high temperature, the oil particles condensed on the surface of the cavity wall 1111 can melt and drip off, thus eliminating the need for frequent disassembly and cleaning of the germicidal lamp assembly 1, achieving automatic cleaning of the germicidal lamp assembly 1, and effectively improving the sterilization efficiency and service life of the germicidal lamp assembly 1.

[0044] In some embodiments, such as Figure 3 and Figure 4 As shown, a lens 14 is provided at the opening, and light rays heading towards the opening are formed into parallel rays and emitted through the lens 14. In this way, when the light emitted by the light-emitting element 12 passes through the lens 14, the light rays entering the lens 14 from different angles can be refracted into parallel rays, thereby concentrating the illumination of a certain area and improving the sterilization effect and efficiency of the germicidal lamp assembly 1.

[0045] Furthermore, the lens 14 can specifically be a plano-convex cylindrical lens 14, which may have a plane 142 and a convex surface 141 arranged opposite to each other, and the light-emitting element 12 may be located on the side of the lens 14 away from the opening of the optical cavity 111. For example... Figure 4 As shown, it can be understood that the direction of the arrow in the figure can specifically represent the direction of the light path. In this way, the light emitted by the light-emitting element 12 can enter through the convex surface 141 of the lens 14 and exit through the flat surface 142 of the lens 14, so that the light rays entering the lens 14 from different angles can exit in parallel.

[0046] Specifically, lens 14 can be made of fused silica, which can have high light transmittance and refractive index to ensure the refraction effect of light.

[0047] Specifically, such as Figure 3 As shown, the aforementioned plane 142 has a first width (L) parallel to the width direction of the lampshade 11. The value of the first width (L) ranges from 40 to 100 millimeters (mm), for example, 40mm, 60mm, 80mm, 100mm, etc. The aforementioned protruding surface 141 can be an arc surface, and the radius of the circle containing the arc surface ranges from 60 to 160 millimeters (mm), for example, 60mm, 80mm, 120mm, 140mm, 160mm, etc.

[0048] In some embodiments, such as Figures 2 to 4As shown, the lamp cover 11 has a base 112 and a cover 113. The cover 113 has a first end 1131 and a second end 1132. The first end 1131 is connected to the base 112, and an opening is formed at the second end 1132. The light-emitting element 12 is disposed on the base 112, and the heat-generating element 13 is disposed on the cover 113. Alternatively, the cover 113 may be at least partially made of a self-heating material. Thus, the light-emitting element 12 and the heat-generating element 13 can be disposed at different positions on the lamp cover 11, effectively improving the layout rationality of the germicidal lamp assembly 1. Furthermore, the cover 113 may be at least partially made of a self-heating material, thereby effectively simplifying the connection structure of the germicidal lamp assembly 1 and reducing the manufacturing difficulty and cost of the germicidal lamp assembly 1.

[0049] The aforementioned base 112 and cover 113 can be detachably connected or integrally formed. Detachable connection can include snap-fit ​​connection or adhesive connection, etc., which are not specifically limited in this application.

[0050] The two ends of the heating element 13 can be connected to the cover 113 respectively, so as to be movably disposed on the cover 113. For example, the heating element 13 can be snap-fitted or glued to the cover 113.

[0051] At least a portion of the aforementioned cover 113 may be made of a self-heating material, and the cover 113 may generate heat to melt and drip off oil particles adhering to the cavity wall 1111 and the lens 14.

[0052] In some embodiments, such as Figures 3 to 6 As shown, the housing 113 includes a first part 1133 and a second part 1134 connected together. The first part 1133 is closer to the base 112 than the second part 1134. A positioning part 1135 is formed at the connection between the first part 1133 and the second part 1134, and the lens 14 is fixed by the positioning part 1135. In this way, the lens 14 can be positioned at the opening of the optical cavity 111 through the positioning part 1135, so that the lens 14 can be easily and quickly disassembled and assembled when cleaning or replacing it, effectively simplifying the connection between the lens 14 and the housing 113 and improving the ease of lens 14 assembly.

[0053] Specifically, at the connection between the first part 1133 and the second part 1134, a protrusion can be made into the optical cavity 111 to form a positioning part 1135, and the two ends of the lens 14 can respectively abut against the positioning part 1135, thereby limiting the lens 14 to the opening.

[0054] Furthermore, the first part 1133 and the second part 1134 can be detachably connected or integrally formed. Detachable connection can include plug-in connection or adhesive connection, etc., which are not specifically limited in this application. The first part 1133 and the second part 1134 are preferably integrally formed, which effectively simplifies the connection structure of the cover 113 and reduces the manufacturing difficulty and production cost of the cover 113.

[0055] In some embodiments, such as Figures 2 to 6 As shown, at least a portion of the outer wall of the cover 113 is provided with a heating element 13, and at least a portion of the heating element 13 is located on the outer wall of the first portion 1133. The portion of the cover 113 corresponding to the heating element 13 forms a light-transmitting surface 1133a, and the remaining portion forms a light-shielding surface 1134a; or, at least a portion of the cover 113 is made of a self-heating material, and at least a portion of the cover 113 made of a self-heating material is located in the first portion 1133. In this way, the light-transmitting surface 1133a allows the light emitted by the light-emitting element 12 to directly irradiate the heating element 13 through the light-transmitting surface 1133a, thereby causing the heating element 13 to absorb the light and generate heat. The light-shielding surface 1134a can concentrate the light scattered through the opening, avoiding the situation where the light irradiation intensity is insufficient due to the excessive light heat dissipation range, resulting in a poor sterilization effect of the germicidal lamp assembly 1, effectively improving the practicality and sterilization effect of the germicidal lamp assembly 1. In addition, the cover 113 made of self-heating material can be located in the first part 1133, which greatly slows down the loss of heat generated by the cover 113 and effectively improves the self-cleaning effect of the germicidal lamp assembly 1.

[0056] Specifically, such as Figure 3 and Figure 4 As shown, the heating element 13 can be installed on the outer wall of the cover 113, thereby ensuring that the heat generated by the heating element 13 can be directly transferred to the cover 113, effectively reducing heat loss during the transfer process. At the same time, since the heating element 13 is located on the side of the cover 113 away from the oil fumes, the influence or pollution of the heating element 13 by the oil fumes is greatly avoided, effectively improving the cleanliness and reliability of the heating element 13.

[0057] The heating element 13 and the outer wall of the cover 113 can be detachably connected. The detachable connection can specifically include adhesive connection or snap-fit ​​connection, etc., which is not specifically limited in this application.

[0058] In an embodiment not shown, the heating element 13 can be disposed on the inner sidewall of the cover 113, so that the light emitted by the light-emitting element 12 directly irradiates the heating element 13, effectively ensuring the efficiency of light absorption by the heating element 13. Furthermore, the heat generated by the heating element 13 can be directly transferred to the light cavity 111, effectively ensuring the heat transfer of the heating element 13.

[0059] The cover 113 made of the self-heating material can be located in the first part 1133. It is understood that when the light emitted by the light-emitting element 12 shines on the cover 113, the heat generated by the cover can be accumulated at the bottom of the light cavity 111, thereby minimizing the rate at which heat is lost from the opening of the light cavity 111.

[0060] In some embodiments, such as Figure 2 As shown, from the first end 1131 to the second end 1132, the cover 113 gradually increases in size to form a trumpet shape. Thus, the trumpet-shaped cover 113 allows molten oil to drip off the cover 113 and the base 112 under the influence of gravity, preventing oil residue on the cover 113 and the base 112. This achieves automated cleaning of the germicidal lamp assembly 1, effectively improving its practicality and convenience.

[0061] Specifically, with Figure 2 Taking the position of the germicidal lamp assembly 1 as an example, the part of the cover 113 that is higher than the base 112 in the vertical direction, after the oil stains on the second end 1132 of the cover 113 melt, can flow to the first end 1131 of the cover 113 under the action of gravity, and then flow through the base 112 to the part of the cover 113 that is lower than the base 112 in the vertical direction. The part of the cover 113 that is lower than the base 112 in the vertical direction, after the oil stains on the first end 1131 of the cover 113 melt, can flow to the second end 1132 of the cover 113 under the action of gravity. In this way, the oil stains condensed on the surface of the germicidal lamp assembly 1 can drip off under the action of gravity, thereby realizing the automatic cleaning of the germicidal lamp assembly 1.

[0062] In an embodiment not shown, the shape of the cover 113 can be constructed as an arc. The arc-shaped cover 113 can have a large light contact area with the light emitted by the light-emitting element 12, thereby improving the heating efficiency of the heating element 13 or the cavity wall 1111 of the light cavity 111.

[0063] In some embodiments, such as Figure 3 and Figure 4As shown, the lens 14 has a convex surface 141, which faces the base 112. In this way, the light emitted by the light-emitting element 12 on the base 112 can enter the lens 14 through the convex surface 141. The lens 14 can refract and focus light rays entering from different angles into a smaller area, thereby effectively improving the light intensity and sterilization efficiency of the light-emitting element 12.

[0064] In some embodiments, such as Figure 3 and Figure 4 As shown, there are one or more light-emitting elements 12, and the multiple light-emitting elements 12 are arranged in rows and columns at intervals. In this way, the multiple light-emitting elements 12 arranged in rows and columns can not only significantly improve the light intensity of the germicidal lamp assembly 1, but also enable the germicidal lamp assembly 1 to cover a larger irradiation area, thereby further improving the practicality of the germicidal lamp assembly 1.

[0065] Specifically, the distance between the multiple light-emitting elements 12 can be in the range of 15 to 30 millimeters (mm), for example, 15mm, 18mm, 20mm, 25mm, 30mm, etc., so as to ensure uniform illumination of the germicidal lamp assembly 1.

[0066] According to one aspect of this utility model, such as Figure 7 As shown, a range hood 2 is also provided, including a housing 21 and a germicidal lamp assembly 1 as described above. The germicidal lamp assembly 1 is disposed inside the housing 21, and a fan 211 is disposed inside the housing 21, with the opening facing the fan 211. Since the germicidal lamp assembly 1 described above has the aforementioned beneficial effects, the range hood 2 including the germicidal lamp assembly 1 described above also has the aforementioned beneficial effects, which will not be elaborated further here.

[0067] Specifically, the casing 21 can be equipped with an air inlet 2113 and an air outlet 2114. Oil fumes can flow in through the air inlet 2113 and out through the air outlet 2114. The fan 211 can be positioned close to the air outlet 2114 of the casing 21. When the fan 211 rotates, it causes the air inside the casing 21 to flow at high speed, thereby creating negative pressure at the air outlet 2114. This negative pressure draws oil fumes from the air inlet 2113 into the casing 21. Figure 9 As shown, Figure 9 The direction of the middle arrow can specifically represent the direction of airflow along the path.

[0068] Furthermore, the fan 211 may have a top 2111 and a bottom 2112. Compared to the top 2111, the germicidal lamp assembly 1 is positioned closer to the bottom 2112. Since the top 2111 is closer to the air outlet 2114 of the casing 21 than the bottom 2112, it is understandable that the speed of the oil fume flow near the bottom 2112 is less than the speed of the oil fume flow near the top 2111. Thus, the light emitted by the germicidal lamp assembly 1 can come into more full contact with the oil stains or microorganisms in the oil fume, thereby sterilizing the accumulated oil fume and effectively improving the sterilization effect of the germicidal lamp assembly 1.

[0069] In some embodiments, such as Figures 8 to 10 As shown, the casing 21 has a rear panel 212, and the germicidal lamp assembly 1 is mounted on the rear panel 212. In this way, the opening of the light cavity 111 of the germicidal lamp assembly 1 can be directed toward the fan 211 and the airflow path formed by the rotation of the fan 211, effectively ensuring the rationality of the structural layout of the range hood 2.

[0070] In some embodiments, such as Figure 8 and Figure 9 As shown, an airflow path is formed inside the casing 21 via the fan 211. Light rays emitted from the opening pass through the airflow path and are directed towards the fan 211. In this way, the germicidal lamp assembly 1 can simultaneously sterilize the fan 211 while sterilizing the oil fumes. This not only improves the sterilization efficiency of the germicidal lamp assembly 1, but also greatly reduces the frequency of cleaning and maintenance of the fan 211, effectively reducing cleaning and maintenance costs and extending the service life of the fan 211.

[0071] Specifically, when the fan 211 rotates, it can form an airflow path inside the casing 21. The opening of the light cavity 111 is set towards the fan 211, so that the light emitted by the light-emitting element 12 can irradiate the airflow path to sterilize the oil particles in the airflow path, effectively ensuring the sterilization effect of the range hood 2.

[0072] In addition, oil stains and microorganisms in the fumes may adhere to the fan 211. The light emitted by the germicidal lamp assembly 1 can pass through the airflow path and shine on the fan 211, thereby sterilizing the surface of the fan 211 and effectively reducing the growth and spread of microorganisms. Furthermore, as the fan 211 rotates, it can also sterilize the area surrounding the fan 211. Of course, as... Figure 10 As shown, when the range hood 2 is not in operation, the light emitted by the germicidal lamp assembly 1 can directly shine on the fan 211 to prevent bacteria from growing on the surface of the fan 211, thus affecting the cleanliness and service life of the fan 211. Figure 10 The direction of the middle arrow can specifically represent the direction of the light emitted by the germicidal lamp assembly 1.

[0073] In some embodiments, such as Figure 9 and Figure 10 As shown, the lampshade 11 forms a light-emitting surface 1136 at the opening. The light-emitting surface 1136 is inclined to the rear panel 212 of the enclosure, and the light emitted from the light-emitting surface 1136 shines obliquely upward toward the fan 211. In this way, the light emitted by the germicidal lamp assembly 1 can shine obliquely upward to form a larger contact area with the airflow path, thereby further improving the sterilization effect of the germicidal lamp assembly 1, and thus improving the oil fume treatment effect of the range hood 2.

[0074] Specifically, the fumes can enter from the bottom up through the air inlet 2113 of the chassis 21 and be discharged through the air outlet 2114 of the chassis 21. The light emitted from the light-emitting surface 1136 is obliquely upward. The obliquely oriented light can come into contact with the fumes for sterilization, and can even have the same airflow path as the fumes, effectively extending the contact time and contact area between the fumes and the light, further improving the sterilization intensity and sterilization effect of the germicidal lamp assembly 1.

[0075] In some embodiments, the germicidal lamp assembly 1 is detachably connected to the chassis 21. This allows for easy disassembly and assembly of the germicidal lamp assembly 1 when it needs repair or replacement, significantly reducing maintenance costs and assembly / disassembly difficulties, and improving user convenience.

[0076] Specifically, the germicidal lamp assembly 1 and the housing 21 can be connected by fasteners, such as screws or bolts. Of course, in some other embodiments, the germicidal lamp assembly 1 and the housing 21 can also be connected by adhesive bonding, and this application does not specifically limit this.

[0077] In the description of this utility model, it should be understood that the directional terms such as "front", "rear", "up", "down", "left", "right", "horizontal", "vertical", "horizontal", "top", and "bottom" indicate the orientation or positional relationship, which are usually based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description.
