Embodiment Construction

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0020] The breath pulse valve disclosed in the embodiment of the present invention has a simple and compact structure, and can automatically open and close the air circuit according to the human breath, thereby effectively controlling the oxygen delivery amount, supplying oxygen when inhaling, and closing the oxygen supply when exhaling, reducing the Minimize the waste of oxygen, save oxygen consumption and reduce the cost of use.

Abstract

The invention discloses a respiratory pulse valve, which comprises an upper cover, an air inlet section, an air outlet section and a lower cover connected sequentially from top to bottom. After oxygen enters the air inlet section, it is divided into two paths. The air passage of the main valve in the air outlet section is connected with the air outlet connected to the main valve air passage, the second air passage is connected with the pilot air passage set in the air outlet section, and the chamber formed between the air outlet section and the lower cover is formed by The valve disc, valve plate and breathing diaphragm are arranged in sequence from top to bottom. The valve disc moves up and down to open or close the air circuit of the main valve. The pilot air circuit is connected to the chamber between the valve disc and the valve plate. The pilot valve port connected to the chamber, the breathing diaphragm closes or opens the pilot valve port, the breathing air circuit is set on the lower cover to connect to the bottom of the breathing diaphragm, and the breathing air circuit and the air outlet are connected to the breathing mask. The invention can turn on and off the delivery of oxygen according to people's respiration, avoiding the direct discharge of oxygen when exhaling, and achieving the purpose of saving oxygen consumption.

Description

technical field [0001] The invention relates to the technical field of valve assemblies, in particular to a breathing pulse valve. Background technique [0002] At present, in environments such as hospital oxygen use, plateau oxygen use, or health care oxygen use, the oxygen supply equipment controls the on-off through the valve assembly. After the valve assembly is opened, the gas is usually supplied continuously at a fixed flow rate. The output oxygen flow rate of the oxygen supply equipment in the process of exhaling and exhaling is all constant, only when people inhale, oxygen can be effectively used, and when exhaling, the oxygen is all discharged, causing great waste. The traditional valve assembly cannot adjust the oxygen output according to the person's breathing, and cannot shut off the oxygen delivery when exhaling, so the oxygen consumption is large and the use cost is high. Contents of the invention [0003] The technical problem to be solved and the technical...
