The invention provides a breath trainer. The breath trainer consists of a
chassis, a control panel, a filter box, a buffer pot, a
check valve, an air hose, a
nose cover, an air
discharge pipe, a pulse
blood pressure and blood
oxygen detector, an
oxygen enrichment generation device, a flow control device, a pipeline switching valve, a
pressure sensor, a flow sensor and a circuit module; the
oxygen enrichment generation device consists of an
oxygen enrichment membrane component box and a
vacuum pump; the flow control device consists of a first air distribution
barrel, a second air distribution
barrel and a resistance
pipe network; the air discharging
pipe is connected with the
pressure sensor and the flow sensor through
branch pipes; a
liquid crystal display screen and a control key are arranged on the control panel; and the circuit module consists of a singlechip, a voice
chip, a power
amplifier, a
loudspeaker, a program memory, a
data memory, a display circuit, a keyboard circuit and a
signal conditioning circuit. The breath trainer has high intelligent level, can perform human-
machine interaction and increase the training interest, and is capable of selecting a
training load and a
training time according to a parameter input by a user, so a step-by-step exercising effect can be achieved.
