Abstract

A ventilation-type UV light includes a light body, an air guide structure provided at the bottom of the light body, a UV module, a fan and two air inlets; the air guide structure and the light body enclose to form a mounting space, the UV module is installed inside the mounting space; the fan is provided inside the air guide structure, the bottom of the air guide structure is provided with air outlets, the air inlets are provided on the periphery or bottom of the ventilation-type UV light in an encircling way, and both the air inlets and the air outlets access the mounting space. Air can flow into the mounting space along the air inlets and then can be discharged downward via the air outlets after being sterilized and disinfected by the UV module in the mounting space.

First claim

What is claimed is:

1. A ventilation-type UV light used for air sterilization and disinfection, the ventilation-type UV light comprising:
a light body, an air guide structure arranged at bottom of a lamp body, a UV module, a fan and two air inlets; the air guide structure and the light body enclose to form a mounting space, the UV module is installed inside the mounting space; the fan is provided inside the air guide structure, a bottom of the air guide structure is provided with air outlets, the air inlets are provided on a periphery or bottom of the ventilation-type UV light in an encircling manner, and both the air inlets and the air outlets access the mounting space;
wherein, air flows into the mounting space along the air inlets and then is discharged downward via the air outlets after being sterilized and disinfected by the UV module in the mounting space; and
wherein the bottom of the fan is provided with a shielding part that prevents UV rays emitted by the UV module from being leaked.

2. The ventilation-type UV light as claimed in claim 1 , wherein the air guide structure comprises a wind scooper and a baseplate, the wind scooper is a tubular structure with an opening at each end, a top port and a bottom port of the wind scooper access each other, the top port accesses the mounting space, the baseplate is provided at the bottom of the wind scooper, the corresponding the bottom port is provided with a downward the air outlet to make air that flows into the mounting space can pass through the top port and the bottom port and then can be discharged via the air outlet.

3. The ventilation-type UV light as claimed in claim 2 , wherein three projections of the bottom port, the shielding part, and the top port are provided from largest to the smallest in descending order;
and/or the wind scooper also comprises an air guiding plane provided between the top port and the bottom port, and the air guiding plane extends to the air outlet;
and/or the wind scooper comprises a connecting part that is higher than the top port, and the inside of the connecting part is provided with a through-hole;
and/or the fan is a centrifugal fan that enables air to flow into the fan from one end and flow out of the fan from the periphery, the centrifugal fan is provided inside the wind scooper horizontally, and the air inlets of the fan are provided corresponding to the top port;
and/or the wind scooper and the baseplate are connected in a dismountable way;
and/or the wind scooper is provided horizontally.

4. The ventilation-type UV light as claimed in claim 3 , wherein when the bottom of the fan is provided with the shielding part, the air outlets are provided on the baseplate and between the periphery of the bottom port and periphery of the shielding part, and the air outlets are provided along the periphery of the shielding part in an encircling manner;
and/or the shielding part is an independent part, or a bottom lighting module or the middle structure of the baseplate.

5. The ventilation-type UV light as claimed in claim 4 , wherein the ventilation-type UV light has a center line in an up-down direction, the center line passes through the light body, the air guide structure and the fan, the air inlets and/or the air outlets are provided around the center line;
and/or the air guide structure also comprises an indicator light, at least part of structure of the indicator light is exposed to the bottom surface of the air guide structure, and the indicator light is used for displaying the working status of the UV module.

6. The ventilation-type UV light as claimed in claim 5 , wherein the light body and the air guide structure are connected in a dismountable way;
and/or the light body comprises a control box, a driving power supply and a dimmer switch, the dimmer switch is used for regulating the color temperature or power of the ventilation-type UV light;
and/or the inside of the mounting space is also provided with a reflective board, the reflective board is used for increasing reflection of UV rays emitted by the UV module.

7. The ventilation-type UV light as claimed in claim 6 , wherein when the light body comprises the control box, the driving power supply and the dimmer switch, the dimmer switch comprises two opposite buckles, toggling part and plugging hole; the buckles comprise an extension arm and a stuck point; both the buckle and the plugging hole are provided on one end away from the toggling part; the control box is provided with a sliding hole, two the buckles are inserted into the sliding hole, the dimmer switch connects to the control box in a flexible way via the extension arm and stuck point of the dimmer switch; the driving power supply comprises a toggle switch inserted into the plugging hole, and the corresponding gear of color temperature or power can be regulated by sliding the toggling part.

8. The ventilation-type UV light as claimed in claim 2 , wherein the air inlet is formed by the periphery of the light body and periphery of the air guide structure in an enclosing manner, enabling air to flow into the mounting space horizontally, obliquely upward or obliquely downward via the air inlet.

9. The ventilation-type UV light as claimed in claim 1 , wherein the light body comprises a mounting subassembly at the bottom of the light body, the bottom of the mounting subassembly is provided with a groove with a downward opening, the air guide structure is inserted into the groove and encloses with the mounting subassembly to form the mounting space; and
the mounting subassembly comprises a convex part and a lateral margin provided on the periphery of the convex part, the convex part and the lateral margin are of an integral structure, the convex part forms the groove with a downward opening, the air guide structure and the mounting subassembly enclose to form the mounting space and the air inlets, the air inlets are located on the lateral margin; and
the baseplate is provided with a connecting column corresponding to the lateral margin, and the light body and the air guide structure are connected in a dismountable way via the connecting column and corresponding fasteners.

10. The ventilation-type UV light as claimed in claim 1 , wherein the ventilation-type UV light is inserted into the mounting hole of an external bearing part, the mounting hole passes through the upper surface and lower surface of the bearing part, the ventilation-type UV light also comprises at least two mounting subassemblies, the light body comprises a mounting surface against the lower surface of the bearing part; and
