Cyclic drying agent 108 is placed in shell 102, and the absorption of cyclic drying agent 108 steam, temperature increase cycle under room temperature
Steam is discharged in drier 108.In one embodiment, cyclic drying agent 108 is placed in container, and container is placed on shell 102
Bottom.In the illustrated embodiment, the container for accommodating cyclic drying agent 108 is placed on thermoswitch 106, with thermoswitch
106 are located at the bottom of shell 102 together.
Shown in referring to figs. 2 and 3, which further includes the basic structure of headlight：Shell 202, PCB and the LED of headlight
204, lens group 206, lens 208, decorative circle 210 and radiator 212.As shown, fog cancellation element is mounted on headlight
On shell 202, fog cancellation element is located at the top of the radiator 212 of headlight, the thermoswitch 106 in fog cancellation element,
I.e. bimetal leaf is just arranged in the top of radiator, in this way, when headlight works, the heat that radiator 212 generates can be straight
It connects and bimetal leaf is heated.
Fig. 2 discloses structure when headlight is in off position.When headlight does not work, entire lamp body and fog are eliminated
Device is all in room temperature.Thermoswitch, i.e. bimetal leaf tilt upward, not enclosed switch mouth.Gas in headlight lamp body and mist
It (as shown by the arrows in Figure 2, is the gas of gas exchanges that gas in the shell of gas cancellation element carries out gas exchanges by switch mouth
Flow direction).Cyclic drying agent absorbs steam at normal temperatures, due in the shell of gas and fog cancellation element in headlight lamp body
Gas communicate, therefore cyclic drying agent can absorb the steam in entire headlight lamp body, keep the drying of headlight lamp body.
Fig. 3 disclose headlight it is in running order when structure.When headlight works, temperature increases, and radiator fever is located at
Thermoswitch above radiator, i.e. bimetal leaf elevated temperature deformation and enclosed switch mouth.The shell quilt of fog cancellation element at this time
Closing, fog cancellation element are isolated with the lamp body of headlight, no longer carry out gas exchanges.Cyclic drying agent is placed on thermoswitch
On, therefore also heated up by the heating of radiator.Cyclic drying agent heats up and steam is discharged, after steam is discharged in cyclic drying agent
Restore drying regime for using next time.Under the heat effect of radiator, thermal current ramps up, and the steam of discharge is in thermal current
Under the action of ramp up, unidirectionally excluded out of shell to outside shell by waterproof ventilated membrane, complete the discharge of steam.It is closed in headlight
After closing.Radiator no longer radiates, and thermoswitch, that is, bimetal leaf restores the heeling condition under room temperature, and switch mouth is opened.It is extensive at this time
Dry cyclic drying agent can absorb the steam in headlight lamp body again again.Since waterproof ventilated membrane only unidirectionally leads to for steam
It crosses, water after cooling can not be entered back through waterproof ventilated membrane in shell.
By the above-mentioned course of work, the headlight fog cancellation element of the utility model is absorbed when headlight does not work every time
Steam is discharged using the fever of headlight when headlight works for steam in headlight lamp body, realizes cyclic absorption steam and row
Go out the process of steam.
The headlight and its fog cancellation element of the utility model absorb the steam in headlight lamp body when headlight does not work,
Steam is discharged using the fever in the headlight course of work when working for headlight, which can recycle, to big
Steam in lamp lamp body carries out stable discharge.
Above-described embodiment, which is available to, is familiar with person in the art to realize or using the utility model, be familiar with ability
The personnel in domain can in the case where not departing from the utility model thought of the utility model, to above-described embodiment make various modifications or
Variation, thus the scope of protection of the utility model is not limited by above-described embodiment, and should meet claims to mention
Inventive features maximum magnitude.
