7. The UV germicidal lamp as recited in claims 1 to 6, characterized in that the choke structure is made of a material having a function of reflecting and/or refracting the UV rays emitted from the UV tube (102); the outer surface of the wind-blocking structure is of a smooth structure.
8. The UV germicidal lamp as claimed in any of claims 1 to 6, wherein the air exhausting structure comprises a fan (108) disposed at the air inlet (103) for sucking outside air into the lamp housing (101) and/or at the air outlet (104) for exhausting air irradiated from the lamp housing (101) through the UV tube (102); a negative ion generator (109) is also arranged in the lamp housing (101); the air inlet (103) and the air outlet (104) of the lamp shell (101) are respectively provided with a shading plate (110) which is made of a material for blocking ultraviolet rays emitted by the ultraviolet lamp tube (102) from transmitting the lamp shell (101) to radiate to the outside.
9. The UV germicidal lamp as claimed in any one of claims 1 to 6, wherein the lamp housing (101) is a vertical structure, and the air inlet (103) and the air outlet (104) are respectively disposed at the bottom and the top of the lamp housing (101).
10. A method of operating a germicidal lamp, wherein the germicidal lamp is an ultraviolet germicidal lamp as claimed in any one of claims 1 to 9, the method comprising the steps of:
turning on a power switch, and electrifying the ultraviolet lamp tube (102);
judging the current state of the ultraviolet lamp tube (102), giving an alarm if the ultraviolet lamp tube (102) is not lightened, and entering the next step if the ultraviolet lamp tube (102) is lightened;
and starting the fan, wherein the modes for starting the fan comprise a manual mode, a timing mode and an automatic mode, and one of the three modes is started alternatively.
11. A method as claimed in claim 10, wherein the manual mode is to manually set a fan operation speed, the fan operation speed includes three steps of high speed, medium speed and low speed; the selectable fan operation time in the timing mode comprises a first operation time period, a second operation time period and a third operation time period, wherein the fan operation mode of any one of the three operation time periods is the same, namely, the fan is operated at a high speed within a set high-speed operation time period firstly, then the fan is operated at a medium speed within a set medium-speed operation time period, and in the rest time, the following steps are repeatedly executed, namely, the fan is in a stop state within a set stop operation time period firstly, and then the fan is operated at a low speed within a set low-speed operation time period until the selected operation time period is finished; the automatic mode is to operate the fan within a set automatic operation time period, and one of the operation modes is the same as the operation mode of the fan in the timing mode.
12. The method as claimed in claim 10, wherein in the step of determining the current status of the uv lamp (102), when the uv lamp (102) can be lighted, if the lighting time of the uv lamp (102) reaches the set accumulated running time, an alarm is issued without stopping the step of starting the fan.
