Further, the spacing of the parallel pole is equal.

Further, the parallel pole is set under waterproof unit surface.

Further, the waterproof subelement is hemispherical lens, a diameter of micron order of hemispherical lens and its following.

Further, the waterproof subelement further includes pedestal, and the hemispherical lens is fixed on basal layer by pedestal.

Further, the section of the pedestal is hexagon or circle.

The beneficial effects of the utility model：The camera lens with self-cleaning function in the utility model, passes through dustproof unit It can polarize, be dusted to dust under the action of electric field force, not only can be antifog with waterproof by waterproof unit, and And the luminous energy light transmittance of camera lens itself can also be greatly improved, to improve shooting effect, the utility model is simple in structure, cost Extremely low and operation is simple and feasible, the monitoring system being particularly suitable under outdoor complex environment uses.

Description of the drawings

Fig. 1 is the structural schematic diagram of the camera lens with self-cleaning function in the utility model embodiment.

Specific implementation mode

Illustrate that the embodiment of the utility model, those skilled in the art can be by this theorys below by way of specific specific example Content disclosed by bright book understands other advantages and effect of the utility model easily.The utility model can also be by addition Different specific implementation modes are embodied or practiced, and the various details in this specification can also be based on different viewpoints and answer With carrying out various modifications or alterations under the spirit without departing from the utility model.It should be noted that the case where not conflicting Under, the feature in following embodiment and embodiment can be combined with each other.

It should be noted that the diagram provided in following embodiment only illustrates the basic of the utility model in a schematic way Conception, component count, shape when only display is with related component in the utility model rather than according to actual implementation in schema then And size is drawn, when actual implementation kenel, quantity and the ratio of each component can be a kind of random change, and its assembly layout Kenel may also be increasingly complex.

The camera lens with self-cleaning function in the present embodiment, including eyeglass, eyeglass include basal layer, on the basal layer It is provided with automatically cleaning unit, the automatically cleaning unit includes dustproof unit and waterproof unit, and waterproof unit includes several size phases Same waterproof subelement, multiple waterproof subelement close-packed arrays are at honeycomb-type structural；The dustproof unit includes spaced apart Parallel pole, the parallel pole are multiple, and are alternately connected with the power supply of two-phase or more successively.

In the present embodiment, waterproof subelement structure as shown in Figure 1, multiple waterproof subelement close-packed arrays at honeycomb type The top of structure, waterproof subelement is hemispherical, forms lens arrangement, and hemispherical lens is arranged on pedestal, and pedestal can be Hexagon may be circular configuration, can be formed with the compound eye structural in bionics by this structure, and pass through adjusting The height of lens height, aperture width and pedestal can change incident reflection direction, raising briliancy, change filling rate etc., lead to It crosses and couples light, can effectively improve light utilization.

In the present embodiment, waterproof subelement position hemispherical lens and its hereinafter, makes this at a diameter of micron order of hemispherical lens Compound eye structural in this bionics of kind also has waterproof anti-fog function, and the static state on camera lens surface and water droplet in the present embodiment connects About 155 ° of feeler, roll angle are less than 10 °, have certain anti-fog effect, by being prepared with antifog on optical lens surface The bionic super-hydrophobic structure of performance realizes that the waterproof of optical lens is antifog, can greatly improve optical system in optical instrument Light-transmissive rate, ensure that optical instrument can also work normally under extremely moist environment.

In the present embodiment, the spacing of the parallel pole of dustproof unit is equal, and parallel pole is set to dustproof unit table Under face, efficiency of dust collection is related with frequency, voltage and electrode width, wherein voltage influences maximum to efficiency of dust collection, followed by frequency Rate, electrode spacing influence minimum to the efficiency of dedusting, but if as electrode spacing is too small, will produce Mars, breakdown is serious, passes through Real work is found, more relatively high than the efficiency of dedusting under low frequency state, meanwhile, voltage is higher, and the effect of dedusting is also better, if Electrode spacing is excessive, and electric field is weaker, and dust is not easy to polarize, and efficiency of dust collection is not high, if spacing is too small, interior outfield is cancelled out each other, It is more prone to puncture, is also unfavorable for dedusting.On the other hand, the efficiency of dust collection of different wave is also different, and unified waveform is in difference In the case of duty ratio, efficiency of dust collection is also different, it is preferable that duty ratio is used to be removed for 10% square wave in the present embodiment Dirt.

In the actual work, the spacing of parallel pole is usually grade, and a diameter of micron order of lens, therefore, Principle assumption diagram shown in Fig. 1 only for indicating being placed equidistant with for honeycomb and parallel pole between waterproof subelement, Not structure in actual use.

The above embodiments are only illustrative of the principle and efficacy of the utility model, new not for this practicality is limited Type.Any person skilled in the art can all carry out above-described embodiment under the spirit and scope without prejudice to the utility model Modifications and changes.Therefore, such as those of ordinary skill in the art without departing from the revealed essence of the utility model All equivalent modifications completed under refreshing and technological thought or change, should be covered by the claim of the utility model.
