Abstract
The utility model discloses a laser printer selenium drum relates to the printer equipment field, and this laser printer selenium drum installs back in laser printer, and the battery can provide the electric energy for blowing fan and blower fan, and blowing fan and blower fan blow jointly, can ensure that the inside circulation of air of selenium drum shell is good, prevents the inside moisture increase of selenium drum shell, can ensure the carbon dust and pass through the effect that the electrostatic principle adsorbed on the drum core, improves laser printer's printing effect.
Description
Technical Field
The utility model relates to a printer equipment field, concretely relates to laser printer selenium drum.
Background
The laser printer imaging is to convert the printing signal from computer into pulse signal and to send the pulse signal to laser. At the moment, the charging roller of the laser printer has already finished uniformly charging the surface of the selenium drum, the laser emits laser to offset the charges of the image part on the selenium drum, thus forming invisible electrostatic images on the selenium drum, and the carbon powder on the developing roller is adsorbed to the drum core through the electrostatic principle, so that the images can be observed on the selenium drum by naked eyes at the moment. Then transfer printing is carried out by the transfer printing roller, because the voltage carried on the transfer printing roller is higher than the voltage on the drum core, the carbon powder on the drum core is pulled to the paper, at the moment, the image and text to be printed are formed on the paper, but the carbon powder floats on the paper surface and can be slightly erased by hand, so the carbon powder can be melted and permeated into the fiber of the paper after the heat and pressure are applied by the transfer printing roller, and finally, the whole imaging process is realized. The internal structure of the existing selenium drum is more traditional, the ventilation performance in the sealed shell is poor, the interior of the shell is easy to wet, carbon powder is adsorbed on the drum core through the electrostatic principle, and the printing effect of a laser printer is poor.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the main technical problem who solves provides a laser printer selenium drum, can effectively improve the inside ventilation performance of selenium drum, and the guarantee carbon dust passes through the effect that the static principle adsorbed on the drum core, improves laser printer's the printing effect.
In order to achieve the above object, the present invention provides the following technical solutions:
this laser printer selenium drum includes the selenium drum shell, and selenium drum shell internally mounted has carbon powder storehouse, sensitization drum, useless powder storehouse, and fan and the induced draft fan of blowing are installed respectively to the both sides of sensitization drum, and selenium drum shell internally mounted has the battery, and the battery passes through the electric wire and is connected with fan and the induced draft fan of blowing.
As a further optimization of the technical scheme, the blowing direction of the blowing fan is the same as that of the suction fan.
As a further optimization of the technical scheme, the storage battery is a lithium battery.
The beneficial effect of adopting above technical scheme is: this laser printer selenium drum installs back in laser printer, and the battery can provide the electric energy for blowing fan and suction fan, and the fan of blowing and suction fan are bloied jointly, can ensure that the inside circulation of air of selenium drum shell is good, prevents the inside moisture increase of selenium drum shell, can ensure the carbon dust and pass through the effect that the static principle adsorbed on the drum core, improves laser printer's the effect of printing.
Drawings
The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.
Fig. 1 is a schematic structural diagram of the selenium drum of the laser printer of the present invention.
Wherein, 1-carbon powder storehouse, 2-selenium drum shell, 3-sensitization drum, 4-waste powder storehouse, 5-blowing fan, 6-induced draught fan, 7-battery.
Detailed Description
The preferred embodiments of the toner cartridge for a laser printer according to the present invention will be described in detail with reference to the accompanying drawings.
Fig. 1 shows a specific embodiment of the toner cartridge of the laser printer of the present invention:
as shown in fig. 1, this laser printer selenium drum includes selenium drum shell 2, and selenium drum shell 2 internally mounted has carbon powder storehouse 1, sensitization drum 3, useless powder storehouse 4, and fan 5 and the aspiration fan 6 of blowing are installed respectively to the both sides of sensitization drum 3, and 2 internally mounted of selenium drum shell has battery 7, and battery 7 passes through the electric wire and is connected with fan 5 and aspiration fan 6 of blowing.
The blowing direction of the blowing fan 5 is the same as that of the suction fan 6, so that the air inside the selenium drum shell 2 can circulate smoothly. The storage battery 7 is a lithium battery, has strong storage capacity and can be charged and used regularly.
This laser printer selenium drum installs back in laser printer, and battery 7 can provide the electric energy for blowing fan 5 and blower fan 6, and 5 and blower fan 6 of blowing are bloied jointly, can ensure that 2 inside circulation of air of selenium drum shell is good, prevents the increase of 2 inside moisture of selenium drum shell, can ensure the carbon dust and adsorb the effect on the drum core through the static principle, improves laser printer's the effect of printing.
The above is only the preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, many variations and modifications can be made without departing from the inventive concept, and these all fall into the protection scope of the present invention.
