A cooling type flame retardant trash can

Abstract

The invention discloses a cooling-type flame-retardant trash can, which comprises a trash can. Two straight plates are symmetrically fixedly connected to the upper edge of the trash can, and a protective cover is fixedly connected to the upper ends of the two straight plates. The trash can There is a water storage cavity at the bottom. The advantage is that the negative pressure chamber and the intake pipe are in a nearly vacuum state through the negative pressure mechanism. Once combustion occurs in the trash can, the internal temperature rises, and the heat is conducted to the shape memory alloy through the heat conduction ring plate. The shape memory alloy is deformed and the twist valve Rod, open the ball valve; under the action of atmospheric pressure, the water in the water storage chamber overcomes the gravity and accumulates in the negative pressure chamber through the water inlet pipe. The self-closing delay valve automatically opens under the action of water pressure, and the water in the negative pressure chamber passes through The water channel flows to the transfer cavity and flows out through the watering hole, thereby cooling the combustibles in the trash can, completing fire extinguishing, and avoiding harmful gases generated by continuous combustion, which will affect the health of pedestrians.

Description

technical field [0001] The invention relates to the technical field of garbage cans, in particular to a cooling type flame-retardant garbage can. Background technique [0002] Generally, in order to maintain the urban environment in the city, trash cans are installed in various public places. Citizens put all kinds of flammable garbage into the trash cans, often including unextinguished cigarette butts, which are more likely to burn in the trash cans, producing dense Smoke, dense smoke contains a large amount of harmful gases, while polluting the environment, it also affects the health of pedestrians. However, there is no garbage can in the traditional technology that can carry out fire extinguishing treatment to the garbage can. [0003] To solve the above problems, we propose a cooling type flame retardant trash can. Contents of the invention [0004] The purpose of the present invention is to solve the problems in the background technology, and propose a cooling type f...
