A foot-operated pneumatic flushing switch

Abstract

The invention discloses a foot step type pneumatic flushing switch. The pneumatic flushing switch comprises a buckle cover and an air pressure cap, wherein a circular opening is formed in the center of the buckle cover, the air pressure cap is a spherical cap with a circular ring edge, the pneumatic flushing switch also comprises an air guide plate which is a circular plate, the central area of the circular plate bulges upwards to form a circular boss concentric with the circular plate, an air guide concave port sinking downwards is machined in the center of the circular boss, an air jet nozzle is fixedly mounted on the side surface of the air guide concave port, a vent hole communicating with upper and lower surfaces is machined in the circular boss, stainless steel micropores are mountedin the vent hole, the one-way air jet nozzle communicates with an inner cavity of the air guide concave port, the air pressure cap is buckled on the circular boss, the circular ring edge of the air pressure cap is attached to the surface of the circular plate around the circular boss, an air pressure cavity is formed between the air pressure cap and the circular boss, the buckle cover is buckledon the air pressure cap and fixedly connected with the air pressure cap, and the spherical bulge of the air pressure cap bulges upwards to form a circular opening. The foot step type pneumatic flushing switch has the benefits of the stable structure and long service life.

Description

technical field [0001] The invention relates to the field of sanitary ware, in particular to a foot-operated pneumatic flushing switch applied to a toilet. Background technique [0002] The flushing toilet facilitates the problem of going to the toilet for urban residents. Now, many families and hotels use hand-pressed flushing switches. Every time after going to the toilet, you need to touch the switch with dirty hands, which is easy to cause cross-infection and is very unhygienic. [0003] In order to solve the above problems, those skilled in the art use foot-operated flush switches, which are generally divided into two types: mechanical switches and pneumatic switches. Compared with mechanical switches, pneumatic switches have the advantages of simple structure and low wear Small size, stable performance and long service life. For example, the existing patent number is: 201120490088.1, and the patent name is: a utility model patent for a toilet with a floor-mounted flu...
