Problems solved by technology
But the following problems occurred: A. After printing for a period of time, the anti-pollution cover should be opened to wipe off the dew containing harmful particles on the inner wall of the anti-pollution cover, but the operator often forgets this
B. Since the joint between the anti-pollution cover and the main body of the printer is difficult to seal, the gas containing harmful particles will leak out from the gap 21 at the joint to pollute the environment

Embodiment Construction
[0023] (See figure 1 ) The prior art of patent CN200920295274.2 is to set an anti-pollution cover 2 above the laser printer host 1, and the anti-pollution cover is connected to the laser printer with a hinge 3. The front portion in the anti-pollution cover is provided with a dust cloth 4 of soft material (see Figure 8 and Figure 9 ). When the laser printer was printing, the printed paper rushed through the dust cloth 4 made of soft material and stopped on the cardboard 5 . And the mixture of harmful particles and hot gas emitted from the laser printer is blocked in the anti-pollution cover 2 . The mixture of harmful particles and hot air is cooled and condenses into dew on the inner wall of the anti-pollution cover, thereby effectively preventing harmful particles from polluting the office environment.
[0024] But, when the dew on the top of the dust-proof cloth 4 is too much, it will drip down and wet the dust-proof cloth 4, and the wet dust-proof cloth 4 will wet the ...

The invention relates to a method for clearing harmful particles produced during the working of a laser printer. The method is characterized in that: two side slots and a rear slot are formed on a printer host; correspondingly, two side plates and a rear plate are arranged on an anti-pollution cover additionally; the three plates are connected with one another and enter the three slots in a vertical direction; a water-stopping strip is arranged above a piece of dustproof cloth of the anti-pollution cover; a sewer communicated with the rear slot is formed on the rear part of the host; an evaporating disk is arranged on the lower part of the sewer; a mixture of the harmful particles and hot air from the laser printer is refrigerated on the inner wall of the anti-pollution cover and condensed into dews; the dews flow into the three slots along the inner wall of the anti-pollution cover and the water-stopping strip to form a water seal at the combination position between the host and the anti-pollution cover; and if the dews are excessive, the dews overflow from the rear slot and flow into the evaporating disk through the sewer to be dried naturally. Therefore, the harm of the harmfulparticles scattered during printing of the laser printer to the body health of operating personnel can be prevented effectively.
Description
technical field [0001] The invention relates to an office equipment, in particular to an anti-pollution laser printer. Background technique [0002] At present, the laser printer commonly used in the office is a pollution source of the indoor environment. One of the main consumables of the existing laser printer is ultra-fine toner. The extremely fine particles of toner have a great impact on the human body. They can effectively penetrate into the human lungs. parts, resulting in serious health hazards. Foreign researchers also concluded that in a closed office space, the level of particles in the air is five times higher when the printer is working than when it is not working. Patent CN200920295274.2 (a laser printer with an anti-pollution cover) discloses a laser printer with an anti-pollution cover (see figure 1 ), this technology more effectively blocks the mixture of harmful particles and hot gas emitted from the laser printer in the anti-pollution cover 2; makes the ...
