Description

Air duct opening structure with ultraviolet germicidal lamp

The present invention relates to an air duct opening structure, in particular to an air duct opening structure with an ultraviolet germicidal lamp.

In the conventional technology, there are already many UV germicidal lamp devices that can be installed in offices or other artificial work spaces, and use ultraviolet irradiation to sterilize the work space. Since the ultraviolet rays projected by UV germicidal lamps can cause harm to the human body, the UV germicidal lamps must be turned off when there are people or animals in the room, and turned on when there are no people or animals.

However, the traditional frequent turning on and off of UV germicidal lamps will make operators very tired. If automatic operation is used to automatically turn on and off the UV germicidal lamp, on the one hand, the cost will be increased, and on the other hand, the life of the UV germicidal lamp will be reduced. In addition, indoor spaces often have people inside for a long time. If the UV germicidal lamp can only be turned on when no one is detected in the indoor space, the UV germicidal lamp will not be turned on most of the time. For example, during the daytime hours in the office, people are in the office most of the time, so the sterilization effect cannot be achieved.

This case hopes to propose a brand-new design that can still turn on the UV germicidal lamp for a long time when there are people in the indoor space, thereby achieving better sterilization effect and solving the above-mentioned previous technical shortcomings.

Therefore, the purpose of the present invention is to solve the above-mentioned problems in the conventional technology. The present invention proposes an air duct opening structure with an ultraviolet germicidal lamp. A UV germicidal lamp is arranged inside the air duct opening. When the air of the air conditioning system passes through the air duct opening, When the air duct is opened, the UV germicidal lamp can be used to sterilize the passing air and then discharge it into the room. Since the UV germicidal lamp is arranged inside the air duct opening, it will not illuminate the indoor space. Therefore, even if there are people in the indoor space, the air will still be discharged into the room. The UV germicidal lamp can be turned on continuously for a long time, so it can achieve the desired sterilization effect. And there is no need to manually switch the UV germicidal lamp on and off, making it very convenient to use. In this case, a windshield can also be configured in the air duct opening to form a flow channel, which can extend the length of the air flow path, increase the irradiation efficiency of the UV germicidal lamp, and achieve better sterilization effects. The structure of this case is quite simple. There is no need to use a detector to detect people to automatically switch on and off the UV germicidal lamp, so it can save costs significantly. The windshield in this case can also be made of materials that allow ultraviolet rays to penetrate, which can increase the range of ultraviolet rays inside the air duct opening. In this case, a reflective layer can also be formed on the inner wall of the air duct opening to reflect ultraviolet rays to increase the utilization of ultraviolet rays.

In order to achieve the above object, the present invention proposes an air duct opening structure with an ultraviolet germicidal lamp, which includes an air duct opening, which is installed in the indoor space for exhaust or air intake. During installation, the air duct opening is used to connect an air duct opening. The air duct opening includes two openings, one opening is the inner end opening close to the inside of the air duct, and the other opening is the outer end opening close to the outside of the air duct; one of the two openings is used for air inlet, Another opening is used for exhaust; and at least one UV germicidal lamp is located in the air duct opening for irradiating ultraviolet rays to kill bacteria in the air; the projection angle of the UV germicidal lamp must be such that the ultraviolet rays will not be directly radiated below the air duct opening.

An air duct opening 10 is installed in an indoor space for air exhaust or air intake. During installation, the air duct opening 10 is used to connect an air duct 1 . The better one is the air outlet. The air duct opening 10 includes two openings 13. One opening 13 is an inner end opening 11 close to the inside of the air duct 1, and the other opening 13 is an outer end opening 12 close to the outside of the air duct 1. Usually, the outer end opening 12 Closer to relevant people. One of the two openings 13 can be used for air inlet and the other opening 13 can be used for air exhaust, and is not limited to the inner end opening 11 or the outer end opening 12 .

The UV germicidal lamp 20 can be a general ultraviolet lamp 21 or an ultraviolet LED lamp 22. The UV germicidal lamp 20 may be in the form of a lamp tube 201 or a series of lamp beads 202. When the UV germicidal lamp 20 is in the form of a series of lamp beads 202, in order to have a better sterilization effect, it can be a row of lamps formed by a plurality of lamp beads 202 in series. The projection angle of the UV germicidal lamp 20 must be such that the ultraviolet rays do not directly radiate below the air duct opening 10 .

The other end of the channel 40 is located at the other opening 13 of the air duct opening 10 , so air can flow from one opening 13 to the other opening 13 of the air duct opening 10 along the flow channel 40 . Overall, the path length of the air flowing in the air duct opening 10 can be extended. Moreover, a windshield 30 is arranged inside the air duct opening 10 to extend the flow channel 40, which can prevent the air opening from being too large and causing insufficient residence time of the air in the air duct opening 10, thereby reducing the sterilization effect of the UV germicidal lamp 20.

The UV germicidal lamp 20 is located in the flow channel 40. Preferably, the at least one UV germicidal lamp 20 can be arranged along the flow channel 40, so as to achieve a better sterilization effect. When the windshield 30 is installed inside the air duct opening 10, it is preferred that the UV germicidal lamp 20 is not disposed close to the outer opening 12 of the air duct opening 10 to avoid irradiation by the UV germicidal lamp 20 to outside personnel, so the UV germicidal lamp 20 can be turned on for a long time.

As shown in FIG. 5 , the at least one windshield 30 can form a curved flow channel 40 for several windshields 30 to extend the overall length of the flow channel 40 and configure multiple UV germicidal lamps 20 .

With the above configuration, since the UV germicidal lamp 20 will not directly illuminate the people below the air duct opening 10, it will not harm the people. Moreover, the UV germicidal lamp 20 can still be turned on and used when there are people. It will not cause the UV germicidal lamp 20 to be unusable when there are people around. This UV is only used when no one is around Germicidal lamp will make the installation effect of the UV germicidal lamp poor.

Figures 1 to 5 show different configurations of the windshield 30 and the UV germicidal lamp 20. The arrows in the figures represent the air flow direction.
