Problems solved by technology

[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

Abstract

The invention discloses a spittoon trash can with a sampling circuit. The spittoon trash can comprises a sputum bag, a box body, a box cover, a solar cell panel and a single chip microcomputer. The bottom of the sputum bag 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 bag is fixed on the side wall of the box body. The end wall of the sputum bag is arc-shaped. The arc length of the end wall of the sputum bag is larger than the length of the side wall of the box body. The output end of the single chip microcomputer is connected with the stepping motor. The single chip microcomputer is arranged in the box cover. An approach switch is arranged on the side wall of the box body. An infrared sensor is arranged in the opening of the sputum bag. The approach switch and the infrared sensor are both connected to the input end of the single chip microcomputer. An amplifying circuit, the sampling circuit and a filter circuit are sequentially arranged between the approach switch and the single chip microcomputer. The sampling circuit comprises an operational amplifier A1, a diode D1, a slide rheostat R4, a capacitor C1, a capacitor C2 and a capacitor C3. The spittoon trash can realizes the purposes of storing sputum conveniently and protecting the environment.

Description

technical field [0001] The invention relates to the field of daily life, in particular to a spittoon trash can with a sampling 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 propose a spittoon trash can with a sampling circuit to achieve the advantages of conveniently storing sputum and protecting the environment in view of the above problems. [0004] In order to achieve ...
