A ring of inflatable sealing belt is arranged on the side edge of the shell, and a one-way inflation valve is arranged on the said inflatable sealing belt. One end of the gas nozzle protrudes from the inner side of the housing of the housing towards the mouth of the user, and one end protrudes from the outer side of the housing of the housing and is connected to the exhalation telescopic pipeline; the positive pressure gas supply interface is connected to the positive pressure gas source; the Both sides of the housing of the housing chamber are symmetrically fixed with fixing belts; the suction safety assembly includes a shell, a fixed column, a spring, a movable piece and a pressure relief hole, the movable piece is placed in the casing, and the spring is sleeved on the fixed column , The lower end is fixed in the U-shaped groove of the movable piece, and the pressure relief hole is arranged on the side surface and the top surface of the shell.

In one technical solution, the housing is a hollow cylinder with a round hole at one end, and the diameter of the movable piece is larger than the diameter of the round hole.

In one technical solution, the air-tight sealing belt is a hollow cavity made of silica gel.

In one technical solution, the casing of the housing cavity is transparent.

In one technical solution, the casing of the housing chamber is semi-ellipsoidal or hemispherical.

Compared with the prior art, the beneficial effects of the utility model are:

The mask of the utility model sets the inspiratory pipeline and the exhalation pipeline respectively, and the positive pressure gas enters the accommodation chamber through the positive pressure air supply gas interface, and the patient realizes the positive pressure inhalation training through the nasal cavity. Exhale gas from the length-adjustable exhalation nozzle in the mouth, thereby realizing positive pressure inhalation training and exhalation training to be carried out synchronously and improving the training effect. The inflatable sealing belt provided by the utility model can make the mask and the face closely fit during breathing training; the setting of the inhalation safety component makes the movable piece pushed up by the gas when the pressure of the positive pressure air supply gas is too high From the start, the gas runs out from the pressure relief hole for pressure relief.

Detailed ways

The following examples are used to illustrate the utility model, but are not used to limit the protection scope of the utility model. Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art. The test methods in the following examples are conventional methods unless otherwise specified.

Embodiment one

As shown in Figures 1 to 2, the utility model is a nasal suction nozzle exhalation mask, which includes a housing cavity housing 1, and an exhalation nozzle 5 and a positive pressure air supply gas interface are arranged on the shell surface of the housing cavity housing 1. 3 and the inhalation safety component 2, a circle of inflatable sealing belt 7 is arranged along the side edge of the housing 1 of the accommodating cavity, and a one-way inflation valve 4 is arranged on the inflatable sealing belt 7, and the inflatable sealing belt 7 is tightly inflated with the user's face Fitting; the exhalation nozzle 5 is hollow cylindrical, one end of the exhalation nozzle 5 protrudes from the inner side of the housing 1 towards the user's mouth, and the other end protrudes from the outer side of the housing 1 and is connected to the exhalation telescopic pipeline 6; The positive pressure air supply gas interface 3 is connected to the positive pressure gas source; the two sides of the housing 1 of the housing chamber are symmetrically fixed with fixing belts 8 .
