Abstract
The invention discloses an automatic dust-removing type digital camera. The automatic dust-removing type digital camera comprises a lens cone of the camera. The automatic dust-removing type digital camera is characterized in that static electricity dust removers are arranged on the inner surface of the lens cone of the camera; the static electricity dust removers are mainly composed of discharge electrode plates or discharge electrode wires, dust collecting electrode plates or dust collecting electrode wires and high voltage direct current power supplies; discharge electrodes are connected with the negative electrodes of the high voltage direct current power supplies; dust collecting electrodes are connected with the positive electrodes of the high voltage direct current power supplies; the dust collecting electrodes are made of flat plates or round tubes. According to the automatic dust-removing type digital camera, the static electricity dust removers are added to the inside of the lens cone of the camera, so that the camera has an automatic dust removing function, and users can take clear pictures as the users like conveniently.
Description
Technical field
The present invention relates to a kind of automatic aspirating digital camera.
Background technology
Along with numeral takes the photograph the development of phase technology, digital camera has become a kind of electronic product that people often use.People can use digital camera to take word and figure, can preserve great mass of data in digital form.Digital camera has greatly enriched the life of people.But, digital camera use process in, nearly all user can run into a unavoidable puzzlement: dust appears in camera lens inside, cause take pictures fuzzy, unintelligible.Especially use out of doors for a long time, this situation is especially serious.
Summary of the invention
For solving above-mentioned existing shortcoming, main purpose of the present invention is the automatic aspirating digital camera providing a kind of practicality, increase electrostatic precipitator in camera lens barrel inside, make camera have automatic dedusting function, the photo of the arbitrary shooting clear of person easy to use.
For reaching above-described object, following technical scheme taked by a kind of automatic aspirating digital camera of the present invention:
A kind of automatic aspirating digital camera, comprise camera lens barrel, it is characterized in that, described camera lens barrel inner surface is provided with electrostatic precipitator, described electrostatic precipitator is formed primarily of discharge plate or discharge plume, collecting polar plate or control of dust polar curve and high-voltage DC power supply, described discharge electrode is connected with high-voltage DC power supply negative pole, and described dust collecting electrode is connected with the positive pole of high-voltage DC power supply, and dust collecting electrode adopts dull and stereotyped or pipe.
Adopt the present invention of as above technical scheme, there is following beneficial effect:
Increase electrostatic precipitator in camera lens barrel inside, make camera have automatic dedusting function, the photo of the arbitrary shooting clear of person easy to use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the fundamental diagram of electrostatic precipitator.
Detailed description of the invention
In order to further illustrate the present invention, be described further below in conjunction with accompanying drawing:
As depicted in figs. 1 and 2, a kind of automatic aspirating digital camera of the present invention, comprise camera lens barrel 1, described lens barrel inner surface is provided with electrostatic precipitator 2, described electrostatic precipitator is formed primarily of discharge plate or discharge plume, collecting polar plate or control of dust polar curve and high-voltage DC power supply 4, described discharge electrode 3 is connected with high-voltage DC power supply negative pole, and dust collecting electrode 5 is connected with the positive pole of high-voltage DC power supply.The operation principle of electrostatic precipitator utilizes HVDC non-uniform electric field that the gas molecule in flue gas is ionized, produce a large amount of electronics and ion, move to the two poles of the earth under the effect of electric field force, the dust granules encountered in moving process in air-flow makes it charged, Charged moves to opposite polarity pole plate or polar curve with flow separation under electric field force effect, Charged is adsorbed on pole plate or polar curve by electrostatic force when arriving pole plate or polar curve, thus the camera lens of purification camera.Due to reasons such as radiation frictions, containing a small amount of free ion in air, depending merely on these free ions is impossible make the grit in dust laden air fully charged.Therefore, electrostatic be utilized to make dust separation must possess two primary conditions, one is there is the electric field making dust charged; Two is there is the electric field making Charged particle separation.Electrostatic precipitator in camera lens inner surface is fixing as shown in Figure 1 increases high voltage electric field, the wiring of its discharge electrode and dust collecting electrode is: discharge electrode connects the negative pole of high-voltage DC power supply, dust collecting electrode ground connection is positive pole, and dust collecting electrode can adopt flat board, also can adopt pipe.
Under electric field action, the free ion in lens barrel air will move to the two poles of the earth, and voltage is higher, electric-field intensity is higher, and the movement velocity of ion is faster.Due to the motion of ion, interpolar defines electric current.During beginning, the free ion in lens barrel air is few, and electric current is less.After voltage is elevated to certain numerical value, the ion near discharge electrode obtains higher energy and speed, and when they clash into the neutral atom in air, neutral atom can resolve into positive and negative ion, and this phenomenon is called air ionization.After air ionization, due to chain reaction, greatly increase at the number of ions of interpolar motion, the electric current showing as interpolar sharply increases, and so just can carry out automatic dust removing to lens barrel.
The above is only preferred embodiment of the present invention, not does any pro forma restriction to structure of the present invention.Every above embodiment is done according to technical spirit of the present invention any simple modification, equivalent variations and modification, all still belong in the scope of technical scheme of the present invention.
