Garbage can applying frictional electrostatic negative pressure adsorption

Abstract

The invention discloses a garbage can applying frictional electrostatic negative pressure adsorption. The garbage can structurally comprises a starter, vent holes, a garbage can body, a wire and an exhaust fan. Compared with a traditional garbage can, under the action of the exhaust fan and exhaust guide pipes, negative pressure is formed in the garbage can, therefore, a plastic bag is adsorbed tobe closely attached to the inner wall of the garbage can, and the condition that the plastic bag is sucked into the garbage can when the exhaust fan conducts exhausting is prevented through a filtering grid; under the action of an air guiding pipeline and an air flow diverter, air exhausted by the exhaust fan is guided and diverted, and sharp corners of flow diverting sharp edges are better usedfor air flow diverting; under the action of a friction heating device, diverted air flow blows a circular-arc-shaped swinging rod to swing around a movable column, and then a chemical fiber layer is driven to swing to achieve friction with an iron outer ring to enable the temperature of the iron outer ring to be increased; and under the action of a thermoelectric device, electrons in the iron outer ring move to a copper inner ring through an electrostatic conductor, and then the copper inner ring has the static electricity to adsorb the plastic bag.

Description

technical field [0001] The invention relates to the technical field of environmental protection, more precisely, it relates to a trash can which is adsorbed by frictional static negative pressure. Background technique [0002] Sewage disposer has another name called litter box or litter box, refers to the place where rubbish is installed. Most of them are made of metal or plastic, and they are put into plastic bags when used. When there is a lot of garbage, they can be tied up and thrown away. However, when putting a plastic bag on the trash can, due to the certain adhesion in the trash bag, the plastic bag cannot be attached to the inner wall of the trash can, which affects people's use. The current technical considerations are not comprehensive and have the following disadvantages: [0003] When putting a plastic bag on the trash can, due to the certain adhesiveness inside the trash bag, the plastic bag cannot fit the inner wall of the trash can, and people need to bend d...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a trash can that utilizes frictional electrostatic negative pressure adsorption to solve the problem in the prior art that when the plastic bag is put on the trash can, the garbage bag has a certain degree of adhesion. The plastic bag cannot fit the inner wall of the trash can. People need to bend over and press the plastic bag with their hands to fit it to the inner wall of the trash can, which makes it more troublesome for people to use the trash can and affects people's use.
