Abstract

The invention discloses a respiration simulator. The respiration simulator comprises a base, wherein an air inlet and an air outlet are formed in the base, a respiration cavity is formed in the base,a piston assembly is arranged in the respiration cavity, a driving mechanism is arranged on the upper portion of the respiration cavity, and the driving mechanism drives the piston assembly to move upand down so that air can be exhaled into the respiration cavity from the air inlet and exhaled out from the air outlet. According to the breathing simulator, breathing is simulated in the mode that the piston is driven by the screw, the structure is simple, the respiration simulator is convenient to use, and production cost is low; and the water tank is arranged in the breathing simulator base, so the exhaled air carries water and is closer to the real breathing condition of the human body.

Description

technical field [0001] The invention relates to the field of testing equipment, in particular to a breathing simulator. Background technique [0002] Products need to be tested before leaving the factory to check whether their performance meets the requirements or whether their quality passes the test. Therefore, corresponding testing equipment is required, and the breathing simulator is such a testing equipment. Breathing simulators are used to simulate human breathing conditions and test corresponding products, such as mask testing. [0003] However, the complex structure of existing breathing simulators brings great inconvenience to production and operation, such as the open (announcement) number: a kind of breathing simulator disclosed by CN205050459U, and the exhaled gas of the existing simulator does not have moisture, which does not meet the requirements of The reality of human breathing. Contents of the invention [0004] The present invention aims at the problem...
