Description

Technical Field

[0001] The present invention relates to the technical field of isolation boxes, and more specifically, to an isolation box for a laser printer. Background Art

[0002] A laser printer is a common printing device. Its working principle is to use a laser beam to generate an electrostatic latent image on the drum, then absorb toner, and then print the image or text on paper through steps such as transfer and fixing. Laser printers have the advantages of fast printing speed, high print quality, clear resolution, and low noise. It can handle a large number of printing tasks and is suitable for use in offices, schools, enterprises and other places. During the printing process, the laser printer first processes and encodes the content to be printed, and then controls the scanning of the laser beam to make the charged part of the drum surface form an electrostatic latent image corresponding to the printed content. Then, the charged toner is absorbed to the electrostatic latent image area of ​​the drum, and then the toner image is transferred to the paper through transfer, and the toner is firmly attached to the paper after heating and fixing.

The present invention isolates the printer body by designing a box body, which can prevent a large amount of moisture in the external air from invading the interior of the printer body, and designs an air circulation component. The fan is used to guide the air in the purification box into the fan through the air outlet pipe, and further guides the air into the box body through the guide pipe. At this time, the purification box is continuously exhausted by the fan, and the purification box guides the air inside the box body into the purification box through the air inlet pipe, forming an air circulation effect. The air humidity inside the box body is relatively high and contains toner particles. The turbid moist air flows into the clean air channel in the purification box through the air inlet pipe. The lime particles in the multiple lime grooves on the lime bin board at the bottom of the clean air channel absorb the moisture in the air, and the activated carbon block can adsorb the toner particles in the air, making the air purer, ensuring that the internal environment of the box body is relatively dry and clean, and solving the problem that the air humidity is relatively high during the rainy season in the southern region, which easily causes the electronic components inside the printer to be damp, causing short circuits and corrosion.

Through the work of the air circulation component, the dryness of the air inside the box body is further improved, and the problem that the air humidity is high during the rainy season in the southern region, which easily causes the electronic components inside the printer to be damp, causing short circuits and corrosion, is further solved.

[0030] 3.

[0051] The present invention isolates the printer body 3 by designing the box body 101, so as to prevent a large amount of moisture in the external air from invading the interior of the printer body 3. The air circulation component 2 is designed to guide the air in the purification box 201 into the fan 204 through the air outlet pipe 203, and further guide the air into the box body 101 through the guide pipe 205. At this time, the purification box 201 is continuously ventilated by the fan 204, and the purification box 201 vents the interior of the box body 101 through the air inlet pipe 202. The air is guided into the purification box 201 to form an air circulation effect. The air humidity inside the box body 101 is relatively high and contains toner particles. The turbid wet air flows into the clean air channel 210 in the purification box 201 through the air inlet pipe 202.

[0052] In the embodiment of the present invention, a plurality of arc grooves 2014 are provided on the inner wall of the purification box 201, the fixing frame 207 comprises a frame 2071 and a support plate 2075 connected to the inner wall of the purification box 201, a arc protrusion 2072 is provided on the side wall of the frame 2071, a bearing block 2073 is connected to the bottom of the frame 2071, a diagonal support plate 2074 is connected to the top surface of the frame 2071, an arc groove 2082 matching the arc protrusion 2072 is provided on the side wall of the lime bin plate 208, and an arc protrusion 2083 matching the arc groove 2014 is provided on the other side wall of the lime bin plate 208;

The air enters the air intake fan 204, and further flows into the box body 101 through the guide pipe 205 at the output end of the fan 204. At this time, the purification box 201 is continuously exhausted by the fan 204. The purification box 201 guides the air inside the box body 101 into the purification box 201 through the air intake pipe 202, forming an air circulation effect. The air humidity inside the box body 101 is relatively high and contains toner particles. The turbid moisture flows into the clean air vent in the purification box 201 through the air intake pipe 202. In the clean air channel 210, the lime particles in the multiple lime grooves 2081 on the lime bin plate 208 at the bottom of the clean air channel 210 absorb moisture in the air. The clean air channel 210 is affected by the interaction of the multiple lime bin plates 208 and the arc-shaped curved surface structure of the lime bin plate 208, which makes the clean air channel 210 line longer and the air circulation is blocked, and the speed is reduced, which increases the time for the lime particles to absorb moisture in the air and improves the dehumidification effect. When the air flows to the position of the activated carbon block 209, the activated carbon block 209 adsorbs impurities and can adsorb toner particles in the air, making the air purer. The air further flows to the air outlet channel 2 212 through the air outlet channel 1 211, and finally is guided into the interior of the box body 101 through the fan 204. Under the continuous circulation, the internal environment of the box body 101 is relatively dry and clean. Finally, the printing work is performed through the printer body 3, the plug board 110 is pulled out from the side wall of the paper output box 104, the printed paper is taken out, and the printing work is completed.

The method for using a laser printer isolation box according to claim 9, characterized in that: The following steps are involved: S1, power on, open the top cover (102), and power on the printer body (3) inside the box body (101); S2, the isolation box is closed, the top cover (102) is closed, the paper box cover (107) is opened, printing paper is put into the paper input box (103), and then the paper box cover (107) is closed, and then the plug plate (110) is inserted into the side wall of the paper output box (104), so that the box body (101) is in a closed state; S3, air circulation, through the operation of the fan (204), the air in the purification box (201) is guided into the fan (204) through the air outlet pipe (203), and the air is further guided into the box body (101) through the guide pipe (205) at the output end of the fan (204). At this time, the purification box (201) is continuously ventilated by the fan (204), and the purification box (201) guides the air inside the box body (101) into the purification box (201) through the air inlet pipe (202), thereby forming an air circulation effect; S4, dehumidification and powder removal. The air inside the box body (101) has a high humidity and contains toner particles. Turbid wet air flows into the clean air channel (210) in the purification box (201) through the air inlet pipe (202). The lime particles in the multiple lime grooves (2081) on the lime bin plate (208) at the bottom of the clean air channel (210) absorb moisture in the air. The clean air channel (210) is affected by the interaction of the multiple lime bin plates (208) and the arc-shaped curved surface structure of the lime bin plate (208), causing the line of the clean air channel (210) to become The air circulation is blocked and the speed is reduced, which increases the time for the lime particles to absorb moisture in the air and improves the dehumidification effect. When the air flows to the position of the activated carbon block (209), the activated carbon block (209) absorbs impurities and can absorb toner particles in the air, making the air purer. The air further flows through the air outlet channel 1 (211) to the air outlet channel 2 (212), and finally is guided into the box body (101) through the fan (204). Under the continuous circulation, the internal environment of the box body (101) is relatively dry and clean. S5, printing, performing printing work through the printer body (3), pulling out the plug plate (110) from the side wall of the paper output box (104), taking out the printed paper, and completing the printing work.
