The auxiliary components perform one or all functions such as supporting, shaping, forming passages, adjusting flow direction, etc.

The resistance adjusting component can be a component capable of adjusting respiratory resistance and also can be a component with fixed resistance value; if the resistance value is fixed, a plurality of single parts with different fixed resistance values can be arranged, and the device is used progressively from low to high during respiratory training.

The proximal opening of the respiratory training passage is communicated with the respiratory tract opening and can be directly communicated, such as placing the proximal opening of the respiratory training passage into an inlet or sleeving the proximal opening of the respiratory training passage at an opening of an mouth and a nose; when the design scheme is that the gas filtering assembly is embedded into the proximal end opening of the respiratory training passage, the proximal end opening is communicated with the respiratory tract opening through the gas filtering assembly opening; after the resistance adjusting component and the passage component are matched for use, a gas passage formed between the resistance adjusting component and the passage component is a respiration training passage, the unfolding surface area of the gas filtering component is larger than the sectional area of the far-end opening of the respiration training passage, and the influence of the resistance of the gas filtering component on the resistance adjusting range of respiration training can be reduced.

The proximal opening of the respiratory training passage is communicated with the airway opening through the opening of the gas filtering assembly, namely, the opening of the gas filtering assembly extends out of the passage to be directly communicated with the airway opening, and the proximal opening of the respiratory training passage is positioned in the passage.

The gas filtering component and the auxiliary component are enclosed to form a gas filtering component inner cavity, which can be formed by enclosing a single blade-shaped gas filtering component and the auxiliary component, or can be formed by enclosing a blade-shaped front blade and a blade-shaped rear blade after being connected into the gas filtering component in a sealing way.

Further, to reduce the volume, at least the distal opening of the respiratory training passageway extends into the interior chamber of the gas filter assembly or the passageway of the interior chamber of the gas filter assembly.

In order to conveniently adjust the air resistance during the breath training, the resistance adjusting component of the breath training component can relatively displace with the passage component when rotating, thereby carrying out the air resistance adjustment during the breath training and/or the inspiration training.

The two gas filtering component inner cavity passages can be two passages arranged on the same gas filtering component, and can also be passages respectively arranged on two independent gas filtering components.

When the channel pipe of the gas filtering component is only connected with the respiratory training component, the inhalation and exhalation resistance training can be performed simultaneously; when the channel pipe is connected with the respiratory training component and the gas barrier component at the same time, separate expiratory training or inspiratory training can be carried out; when two channel pipes are connected with two respiratory training components at the same time, the left and right gas regulating ports can be regulated to be different in cross section areas, namely, different air resistances at the left and right sides, and different air flow distribution at the corresponding two sides can be generated, for example, the nasal septum is provided for a user with deflection.
