The utility model relates to a demisting device for a helmet lens, which belongs to the category of daily necessities. The demisting device is mainly composed of a support seat, a power supply device, a fan device and a fixing device. The fixing device is used to fix the demisting device at a predetermined position for demisting the lens. When demisting, a controller is used to turn on the power supply device to generate electricity and drive the fan device. At this time, the fan device will generate wind force to cause air convection, so that the temperature of the inner space of the helmet lens can be close to the external temperature, and the temperature and humidity of the inner side of the lens can be adjusted, so that water molecules will not adhere to the side of the lens close to the human body. In addition, the overall structure is simple, so it is convenient for users to fix it at will to improve practicality.

Description

The demister of safety cap eyeglass

Technical field

The utility model relates to daily class, and particularly a kind of demister of safety cap eyeglass refers to a kind of demister that utilizes balance temperature difference cross-ventilation mode to prevent the safety cap eyeglass that hydrone adheres to especially.

Background technology

Motorcycle becomes one of topmost instrument on modern's short distance traffic already, and in order to ensure knight's the safety that drives, safety cap has become one of indispensable indispensable accessory of safety, therefore, in order to protect knight's safety, no matter expose to the sun and rain and all must wear safety cap, and present safety cap all can be enclosed a slice hardening lens, gets to face and eyes when driving to avoid foreign matter; Also when covering eyeglass, when breathing the hot gas that is produced, the knight then can cause the temperature in the safety cap to rise, when the too high and temperature of air outside humiture this moment is lower than temperature in the safety cap, then very easy airborne hydrone is attached on the eyeglass, the mist that just is commonly called as, when producing mist on the safety cap eyeglass, then can cause knight's sight line not good, so very easy meeting accident, in view of this, there is relevant industry the situation of mist to be arranged on the eyeglass in order to separate never to allow, as shown in Figure 1, for original coating antifog film in the view of safety cap eyeglass, it is coating onedeck antifog film 12 on safety cap 1eyeglass 10, thisantifog film 12 is coated on theeyeglass 10,eyeglass 10 original pores are paved, hydrone can't be attached in these pores, therefore then can not produce the phenomenon of mist, though the method can avoideyeglass 10 to produce fog fully, because the mode of this kind coatingantifog film 12 will lose efficacy after a period of time, therefore if will keep the anti-fog effect of safety cap 1eyeglass 10, then must after a period of time, just be coated with onetime antifog film 12, so it is very inconvenient for the knight, therefore, other has mode that the people utilizes heating wire as shown in Figure 2, for original heating wire that is sticked in the view of safety cap eyeglass, fixed intervals just are provided with aheating wire 22 onsafety cap 2eyeglasses 20, therefore wheneyeglass 20 produces fog, then to heatingwire 22 energising heat conduction, mode by heat energy can not hazeeyeglass 20, but because the mode of thiskind heating wire 22, when starting, must expend more electric energy, utilize battery powered words then the power supply in the battery will soon to be exhausted if be, and must constantly change battery, therefore pass through the situation of the very easy generation electric weight of the mode deficiency of heating wire.

The utility model content

Main purpose of the present utility model is to provide a kind of demister of safety cap eyeglass, solves the problem that existing safety cap is coated with the inconvenience of protecting film repeatedly and powered battery electric weight deficiency takes place easily.

The utility model is mainly by bearing, electric supply installation, fan assembly and fixture constitute, utilize fixture to allow demister be fixed in the precalculated position that supplies the eyeglass demist, when carrying out demist, can utilize controller to open electric supply installation to produce electric power and to drive fan assembly, fan assembly then can produce wind-force and cause cross-ventilation at this moment, since this air to flow greater than the hot gas amount that breathe to produce, and regulate eyeglass medial surface humiture, therefore can allow the temperature convergence and the external temperature of eyeglass inner space of safety cap close, therefore can not allow hydrone be attached to eyeglass near on the side of human body, in addition, its overall structure is simple and easy so be convenient to the user and be fixed on the appropriate location arbitrarily to improve practicality.

The utility model is specifically formed:

One bearing, this bearing are provided with at least one fixture in the pre-position;

At least one electric supply installation, this electric supply installation is connected in this bearing, and is electrically connected with a controller; And

At least one fan assembly, this fan assembly is connected in the precalculated position of this bearing, and becomes an electric connection with this electric supply installation.

Wherein this bearing is provided with this fan assembly place, then is equipped with a ventilating opening that connects for a guide duct of extraneous air circulation.

Wherein the cross-ventilation that is caused after this fan assembly running is greater than respiratory capacity;

Wherein this electric supply installation is an external circuits;

Wherein this electric supply installation is a battery;

Wherein this eyeglass further be snow goggles or goggles independent use one of them.When carrying out demist, can utilize controller to open electric supply installation to produce electric power and to drive fan assembly, fan assembly then can produce wind-force and formed cross-ventilation this moment and since this air to flow greater than breathing the hot gas amount that produces, and regulate eyeglass medial surface humiture.Therefore can allow temperature convergence and the external temperature of eyeglass inner space of safety cap close, therefore can not allow hydrone be attached on the close side of human body of eyeglass.

Advantage of the present utility model is: its overall structure is simple and easy so be convenient to the user and be fixed on the appropriate location arbitrarily to improve practicality, and required electric weight is little, replacing battery that need not be regular, and overall structure is simple and easy and light and handy, being easy to the knight carries, because overall structure is simple and easy so cheap for manufacturing cost, also can reduce commercial value; Because of the air conducting amount greater than respiratory capacity more than three times, so can antifogging and keep eyeglass can not haze.
