Description

Sterilizing lamp assembly and range hood Technical Field The utility model relates to the technical field of range hoods, in particular to a sterilizing lamp assembly and a range hood. Background With the rise of consumer demands for kitchen sanitation and safety, ultraviolet sterilization technology is gradually applied to the field of range hoods. At present, an ultraviolet lamp is usually arranged at an air inlet of the range hood, and the ultraviolet lamp can be used for sterilizing and disinfecting the oil smoke. Specifically, the ultraviolet light beam irradiates the lampblack to decompose and kill microorganisms in the lampblack, so as to remove bacteria and peculiar smell of the range hood. However, the oil smoke is not fully exposed to the irradiation beam of ultraviolet rays before entering the fan, and the irradiation time is short, so that the disinfection effect is poor. In addition, greasy dirt particles in the lampblack are easy to condense on the surface of the ultraviolet lamp tube to form a shading film, so that the disinfection and sterilization performance of the ultraviolet lamp tube is reduced, and the ultraviolet lamp tube can be disassembled and washed regularly, but the frequent disassembly and washing is complex in operation, time-consuming and labor-consuming, and the service life of the ultraviolet lamp tube is greatly influenced. Disclosure of utility model In order to at least partially solve the problems in the prior art, according to an aspect of the present utility model, there is provided a germicidal lamp assembly, the technical scheme being as follows. The sterilizing lamp component comprises a lamp shade, a luminous piece and a heating structure, wherein the lamp shade is enclosed to form an optical cavity with an opening, the luminous piece is at least partially arranged in the optical cavity, part of light emitted by the luminous piece faces to the cavity wall of the optical cavity, and the other part of the light emitted by the luminous piece faces to the opening, the heating structure is constructed as a heating piece, the heating piece is arranged on the cavity wall, and the heating piece heats by absorbing the light emitted to the cavity wall, or the cavity wall of the optical cavity is made of self-heating materials so as to form the heating structure. According to the sterilizing lamp assembly, the light-emitting piece positioned in the optical cavity emits light outwards through the opening to irradiate the lampblack, so that the lampblack is sterilized. And the side wall of chamber wall can paste and be equipped with the piece that generates heat, and the piece that generates heat can absorb the light that the piece launched, or the side wall of chamber wall can adopt the self-heating material to make to promote its self temperature, so under the effect of high temperature, can make the greasy dirt granule melting drip that the chamber wall surface condensed, thereby need not to dismantle the clearance bactericidal lamp subassembly frequently, realize automatic clearance bactericidal lamp subassembly, promoted the sterilization efficiency of bactericidal lamp subassembly and the life of bactericidal lamp subassembly effectively. Illustratively, the opening is provided with a lens, and light rays facing the opening are emitted through the lens to form parallel light rays. Therefore, when the light emitted by the light emitting piece passes through the lens, the light emitted by different angles into the lens can be refracted into parallel light, so that a certain area range can be intensively irradiated, and the sterilization effect and the sterilization efficiency of the sterilization lamp assembly are improved. Illustratively, the lamp housing has a base and a cover having a first end and a second end, the first end being connected to the base, the opening being formed at the second end, the light-emitting member being disposed on the base, the heat-generating member being disposed on the cover, or the cover being at least partially made of a self-heating material. Therefore, the luminous piece and the heating piece can be arranged at different positions on the lamp housing respectively, and the layout rationality of the sterilizing lamp assembly is effectively improved. In addition, the cover body can be made of self-heating materials at least partially, so that the connecting structure of the sterilizing lamp assembly is effectively simplified, and the manufacturing difficulty and the manufacturing cost of the sterilizing lamp assembly are reduced. Illustratively, the cover includes a first portion and a second portion connected to each other, the first portion being closer to the base than the second portion, a positioning portion being formed at a connection of the first portion and the second portion, and the lens being fixed by the positioning portion. Therefore, the lens can be arranged at the opening of the optical cavity through the positioning part,
