Abstract: A chainsaw includes a chain, a liquid pump assembly, a motor, and a controller. The chain is used for implementing a cutting operation. The liquid pump assembly includes a liquid pump and a motor. The liquid pump is used for releasing a liquid for lubricating or cooling the chain. The motor is used for at least driving the liquid pump to operate. The controller is electrically connected to at least the motor. The controller is configured to, when the liquid pump is in the jammed state, control the liquid pump assembly to enter a throttling mode in which a supplied amount of the liquid is reduced, and when the liquid pump exits the jammed state, control the liquid pump assembly to exit the throttling mode. Technical solutions provided by the present application can determine and release the jammed state of the chainsaw.

Abstract: A plant grow lighting system for stimulating plant growth. The plant grow lighting system includes a growth rack, at least one main plant-lighting lamp and at least one auxiliary plant-lighting lamp. Defining height direction of the growth rack as up-down direction, length direction as front-rear direction, and width direction as left-right direction, where the growth rack includes one or more rack layers; the main plant-lighting lamp is provided on the growth rack, the main plant-lighting lamp includes at least one first light-emitting module to emit light downwards; the auxiliary plant-lighting lamp is provided on the growth rack and includes two second light-emitting modules, the second light-emitting module can emit light in a horizontal direction, and the power of the auxiliary plant-lighting lamp is less than the power of the main plant-lighting lamp. The technical solution of the present disclosure makes it possible to provide uniform illumination conditions for plants.

Abstract: A straight-tube UV light includes a light body, end covers and functional subassemblies, where the light body is a hollow, straight tubular structure; the end cover includes the first end cover and the second end cover provided on the left and the right of the light body, the first end cover, the second end cover and the light body enclose to form a mounting cavity; the functional subassemblies include at least the first light source subassembly and the control power supply, provided inside the mounting cavity, the control power supply used for controlling the first light source subassembly to emit UV rays for sterilization and disinfection. This can simplify the protective structure of the light, reduce the volume of the light and improve the sealing property of the light, and derive other types of UV lights to realize standardization and unification of components of different types of UV lights.

Abstract: A straight-tube UV light. The straight-tube UV light includes a light body, end covers, and functional subassemblies. The light body is of a hollow tubular structure provided in a straight line; the end cover includes a first end cover and second end cover provided on a left and right of the light body, the first end cover, the second end cover and the light body enclose to form a mounting cavity. The functional subassemblies include at least the first light source subassembly and the control power supply, provided inside the mounting cavity, the control power supply controls the first light source subassembly to emit UV rays for sterilization and disinfection. This can simplify the protective structure of the light, reduce the volume of the light, and improve a sealing property of the light.

Abstract: A modular disinfection vehicle. The disinfection component is designed into an independent extensible structure, where there is a light source module between the upper end and the lower end of the disinfection component, the upper end of the disinfection component is the first fixing part, the lower end of the disinfection component is the second fixing part, the upper end of the disinfection component is of a dismountable structure, so that the light source module can be replaced and maintained conveniently; when the quantity of the light source modules needs to be increased or decreased, only components and parts at the upper end or/and the lower end of the disinfection component need to be replaced, there is no need to significantly improve the overall structure of the disinfection vehicle, so that the quantity of light source modules of the disinfection vehicle can be increased or decreased conveniently.

Abstract: A man-free sterilization system control device, circuits, a method and control modules, including a switch control module, a system control module, the first control circuit, the second control circuit and the third control circuit; the system control module respectively connects with a switch control module, the first control circuit, the second control circuit and the third control circuit; the device judges whether there are people in the room in the order of operation of three control devices set indoors, at the door and outdoors, the UV light turns on when it is confirmed that there is nobody in the room, the device turns off the UV light man-freely when it is judged that there may be people in the room. With the turning-on mode and the man-free turning-off function of the device, the UV light can only be turned on for sterilization when there is nobody in the room.

Abstract: A UV panel light including a lamp housing, a UV module, a lighting module and the first control circuit; the lamp housing includes a metal plate body and two end covers, the metal plate body is bent, there are accommodating grooves on one surface of the metal plate body, there is a mounting groove on the other surface of the metal plate body, the end covers connect to the metal plate body, and the end covers cover two ends of several the accommodating grooves. The UV module is provided in any of the accommodating grooves; the lighting module is provided in another the accommodating grooves; the first control circuit is provided in the mounting groove, connects electrically to the UV module and the lighting module and is used for the external power supply, which reduces the structural complexity and improves assembly efficiency of the UV panel light.
