A spittoon trash can with amplifying circuit

Abstract

The invention discloses a spittoon trash can with an amplifying circuit. The spittoon trash can comprises a sputum pocket, a box body, a box cover, a solar cell panel and a single chip microcomputer. The bottom of the sputum pocket is connected to the bottom of the side wall of the box body through a shaft, a stepping motor is arranged on the shaft, the side wall of the sputum pocket is fixed on the side wall of the box body, the side wall of the sputum pocket is made of flexible materials, the end wall of the sputum pocket is in an arc shape, and the arc length of the end wall of the sputum pocket is larger than the length of the side wall of the box body. The solar cell panel is electrically connected with the single chip microcomputer, the output end of the single chip microcomputer is connected with the stepping motor, and the single chip microcomputer is arranged in the box cover. A proximity switch is arranged on the side wall of the box body, an infrared sensor is arranged at the opening position of the sputum pocket, the proximity switch and the infrared sensor are both connected to the input end of the single chip microcomputer, and the amplifying circuit, a sampling circuit and a filter circuit are sequentially in series connection between the proximity switch and the single chip microcomputer. The purposes of storing sputum conveniently and protecting the environment are convenient.

Description

technical field [0001] The invention relates to the field of daily life, in particular to a spittoon trash can with an amplifying circuit. Background technique [0002] At present, spittoons are rarely installed in public trash cans, and air pollution and automobile exhaust emissions make people's respiratory tract produce a lot of phlegm. Even if some trash cans are equipped with spittoons, a small circular The spittoon has a relatively small opening, which is inconvenient for passers-by to spit sputum into the spittoon accurately. In addition, the spittoon is set in the open air. If there is too much sputum, it will cause peculiar smell around the trash can, which is easy to attract flies in summer. Contents of the invention [0003] The object of the present invention is to provide a spittoon trash can with an amplifying circuit to achieve the advantages of conveniently storing sputum and protecting the environment in view of the above problems. [0004] In order to ac...
