Embodiments of the present utility model will be further described below with reference to the accompanying drawings.

According to some embodiments of the present utility model, referring to fig. 1 to 5, an ultraviolet sterilizer is installed at an air inlet or an air outlet of a ventilating duct, and the ultraviolet sterilizer includes a housing 100, an ultraviolet lamp tube 130, and a power supply module 140. The housing 100 is matched to the cross-sectional shape of the ventilation duct so that the housing can be inserted into the ventilation duct. Referring to fig. 1 and 2, a lifting lug 150 is provided on an outer side wall of the housing 100, and the housing 100 can be fixedly mounted on a ventilation duct through the lifting lug 150, and an upper end surface of the lifting lug 150 and an upper side surface of the housing 100 are positioned on the same horizontal plane. Referring to fig. 3 and 4, the housing 100 is a rectangular parallelepiped, the housing 100 has an inner cavity, a plurality of through holes 110 are provided at both upper and lower sides of the housing 100, the inner cavity of the housing 100 is provided with support frames 120, and the two support frames 120 are arranged at intervals in the left-right direction. The ultraviolet lamp tube 130 is positioned in the housing 100 and between the two supporting frames 120, the left end of the ultraviolet lamp tube 130 is connected with the supporting frame 120 positioned at the left side, the right end of the ultraviolet lamp tube 130 is connected with the supporting frame 120 positioned at the right side, and the plurality of ultraviolet lamp tubes 130 are arranged at intervals along the front-rear direction. The power supply module 140 is disposed in the housing 100 and on the left side of the supporting frame 120, and the power supply module 140 is electrically connected to the plurality of ultraviolet lamp tubes 130.

When the gas passes through the ventilation duct, the ultraviolet rays irradiated from the ultraviolet lamp tube 130 can destroy bacteria and viruses in the gas; the through-holes 110 of the housing 100 can ensure that the gas smoothly passes through the housing 100 and the light of the ultraviolet lamp tube 130 can be radiated out of the housing 100.

It can be appreciated that, because the upper end surface of the lifting lug 150 and the upper side surface of the housing 100 are located on the same horizontal plane, when the housing 100 is embedded into the air inlet or the air outlet of the ventilating duct from top to bottom, the lifting lug 150 abuts against the end surface of the ventilating duct, that is, the housing 100 is located in the ventilating duct, and the lifting lug 150 is located outside the ventilating duct and the lifting lug 150 is fixedly connected with the ventilating duct through bolts, thereby saving space.

It is also understood that the vent pipe is applicable to the fields of air conditioners, range hoods, and the like. The ultraviolet sterilizer can be arranged in an air exhaust pipeline of the air conditioner to prevent outdoor air from carrying viruses and bacteria into the room; the ultraviolet sterilizer can be installed at an exhaust duct of the range hood to prevent the gas carrying viruses and bacteria from being directly exhausted to the outside.

It should be noted that, the cross section of the casing 100 in this embodiment is rectangular when the casing 100 is matched with the cross section of the ventilation duct, and the cross section of the ventilation duct is also rectangular; when the cross section of the ventilation duct is in other shapes such as a circle and a triangle, the casing 100 is changed accordingly, so that the casing 100 can be embedded into the ventilation duct, and the outer wall of the casing 100 is tightly attached to the inner wall of the ventilation duct, so that gas is prevented from passing through a gap between the outer wall of the casing 100 and the inner wall of the ventilation duct.

It should also be noted that short wave UVC has a wavelength of 200-275 nm, also known as short wave sterilizing ultraviolet. It has the weakest penetration ability and cannot penetrate most transparent glass and plastics. Short wave ultraviolet rays contained in sunlight are almost completely absorbed by the ozone layer, and are absorbed by the ozone layer before reaching the ground. Degree of injury to human body: UVC in nature is absorbed by ozone layer without reaching the ground, and has negligible effect on skin, but short wave ultraviolet rays are harmful to human body, and can not directly irradiate human body. If the irradiation is direct, the skin can be burned by short-time irradiation, and skin cancer can be caused by long-term or high-intensity irradiation. UVC application field: the ultraviolet lamp tube 130 emits UVC short wave ultraviolet rays. Short wave ultraviolet rays are widely used in hospitals, air conditioning systems, sterilizing cabinets, water treatment facilities, water dispensers, sewage treatment plants, swimming pools, food and beverage processing and packaging facilities, food factories, cosmetic factories, dairy factories, breweries, beverage factories, bakeries, refrigerating rooms, and the like.

According to some embodiments of the present utility model, referring to fig. 3 and 4, a region between the left support frame 120 and the power supply module 140 is a first receiving region 171, and a region between the right support frame 120 and the right side wall of the housing 100 is a second receiving region 172.

The shell 100 can protect the ultraviolet lamp tube 130, and the light of the ultraviolet lamp tube 130 is emitted through the through hole 110, and the connecting wire of the power supply module 140 and the ultraviolet lamp tube 130 can be stored in the first storage area 171 and the second storage area 172, so that the connecting wire is prevented from blocking lamplight and occupying a large amount of space, and the attractive appearance is improved.

According to some embodiments of the present utility model, referring to fig. 3 and 5, the support frame 120 includes a first plate 121 and a second plate 122, the first plate 121 and the second plate 122 are fixedly connected, the first plate 121 is connected to the ultraviolet lamp tube 130, and the second plate 122 is fixedly connected to the lower inner wall of the housing 100.

Preferably, the second plate 122 is positioned at a side of the first plate 121 remote from the ultraviolet lamp tube 130, avoiding that the second plate 122 covers the through-hole 110 to block light of the ultraviolet lamp tube 130.

According to some embodiments of the present utility model, referring to fig. 4, a barrier 160 is provided in the case 100, two barriers 160 are spaced apart in a front-rear direction, a region between the barrier 160 on a front side and a front sidewall of the case 100 is a third receiving region 173, and a region between the barrier 160 on a rear side and a rear sidewall of the case 100 is a fourth receiving region 174.

It can be understood that, referring to fig. 4, since the power supply module 140 needs to be connected to both ends of the ultraviolet lamp tube 130, a connection wire is required to connect the right end of the ultraviolet lamp tube 130, and the connection wire is disposed in the third receiving area 173 or the fourth receiving area 174, so that the connection wire can be prevented from covering the through hole 110 to block the light of the ultraviolet lamp tube 130.

Preferably, the baffle 160 extends in the left-right direction, and the plurality of through holes 110 are located between the two baffles 160, avoiding that the baffles 160 cover the through holes 110 to block the light of the ultraviolet lamp tube 130.

Preferably, the lower side of the baffle 160 is abutted and fixedly connected with the lower inner wall of the housing 100, and the upper side of the baffle 160 is abutted and fixedly connected with the upper inner wall of the housing 100.
