Lever type automatically opened and closed trash can with rear permanent magnet

Abstract

The invention discloses a lever type automatically opened and closed trash can with a rear permanent magnet. The lever type automatically opened and closed trash can comprises a trash can body, and the trash can body is of a square columnar structure. An upper opening is formed in the upper end face of the trash can body, and the edge of the rear side of the upper opening is downwards concaved andis erected with a rotation shaft. One side, facing to the upper opening, of the rotation shaft is connected with a trash can cover plate, and the other side of the rotation shaft is connected with astress lever outwards. The lower part of the tail end of the stress lever is connected with a pull rod. A concave-inward groove channel is formed in the outer wall of the rear end face of the trash can body, and an electromagnet is arranged at the bottom end of the groove channel. The electromagnet comprises an iron core and a coil, and the coil is wound on the surface of the iron core. The lowerend of the pull rod is connected with the rare earth permanent magnet, and the rare earth permanent magnet is erected between the side walls of the two ends of the groove channel. By the way, the lever type automatically opened and closed trash can can utilize the attraction and repulsion of the permanent magnet and the electromagnet and be matched with the lever principle to automatically open and close a trash can cover.

Description

technical field [0001] The invention relates to the field of permanent magnets, in particular to a permanent magnet rear lever type automatic opening and closing trash can. Background technique [0002] Trash can is a very common container for domestic waste in life. Trash cans are also divided into various types according to the type of garbage in the content and the place of use. For wiping feces and other reasons, the trash can lid needs to be kept closed, but it must be kept open when the toilet paper needs to be thrown away. Frequent opening and closing is very inconvenient, so it is necessary to design a trash can lid that can be quickly realized by simple operations. The trash can for the toilet with opening and closing function, and the cover of the trash can is designed with a rotating shaft. If a short-arm lever structure is designed at the rear end of the trash can, coupled with the principle of attraction and repulsion of the electromagnet and the permanent magne...

[0002] Trash can is a very common container for domestic waste in life. Trash cans are also divided into various types according to the type of garbage in the content and the place of use. For wiping feces and other reasons, the trash can lid needs to be kept closed, but it must be kept open when the toilet paper needs to be thrown away. Frequent opening and closing is very inconvenient, so it is necessary to design a trash can lid that can be quickly realized by simple operations. The trash can for the toilet with opening and closing function, and the cover of the trash can is designed with a rotating shaft. If a short-arm lever structure is designed at the rear end of the trash can, coupled with the principle of attraction and repulsion of the electromagnet and the permanent magnet, It can control the opening and closing function of the cover well.
