DETAILED DESCRIPTION

[0020] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figures 1 to 4 As shown, a respirator with an air intake display includes an air bag 1, an oxygen storage bag 2, an oxygen connecting pipe 3, a mask 5 and a pressure regulating mechanism; an air intake valve 11 is provided at one end of the air bag 1, and the oxygen storage bag 2 is connected to the oxygen connecting pipe 3; the other end of the air bag 1 is connected to the pressure regulating mechanism; the pressure regulating mechanism includes an air intake pipe 4, a pressure safety valve 41 and an exhalation valve 42; the air intake pipe 4 is connected to the air bag 1; the pressure safety valve 41 is arranged above the air intake pipe 4 and is connected to the air intake pipe 4. Through the design of the pressure regulating mechanism, accurate control of the internal pressure of the respirator can be achieved. The setting of the pressure safety valve 41 can automatically adjust the pressure to ensure the safety of the respirator during use, and avoid discomfort or harm to the user due to excessive or insufficient pressure; the exhalation valve 42 is arranged below the air inlet pipe 4 and connected to the air inlet pipe 4; the bottom of the exhalation valve 42 is connected to the mask 5; the setting of the exhalation valve 42 enables the user to smoothly expel the gas when exhaling, avoiding the discomfort caused by poor exhalation. At the same time, the connection between the exhalation valve 42 and the mask 5 ensures that the exhaled gas can be quickly discharged and will not accumulate inside the mask 5, thereby improving the comfort of use. A pressure display component is connected to one side of the air inlet pipe 4; the pressure display component is located between the pressure safety valve 41 and the exhalation valve 42. The air intake volume of the respirator can be intuitively displayed through the pressure display component. The breathing rhythm and depth can be adjusted according to the indication of the pressure display component, so as to achieve a better breathing effect. At the same time, the pressure display component is located between the pressure safety valve 41 and the exhalation valve 42, and will not be affected by these two components, thereby ensuring the accuracy of the display.

[0022] like Figure 3 and Figure 4As shown, the air pressure display assembly includes a display 6, a pressure sensing head 61 and a mercury tube 62; the mercury tube 62 is located in the display 6, one end of the pressure sensing head 61 is arranged in the air intake pipe 4, and the other end is connected to the mercury tube 62; the display 6 adopts a transparent structure, and a scale line 63 is arranged on the top of the display 6.

[0023] The display 6 is transparent and contains a mercury tube 62, so that the user can directly observe the movement of the mercury in the tube. At the same time, the scale line 63 provided on the top of the display 6 further enhances the accuracy of the display. The user can judge the position of the mercury in the tube according to the scale line 63, so as to more accurately understand the size of the intake air. This design enables the user to control the breathing rhythm and depth more finely.

[0024] like Figure 2 As shown, a number of auxiliary mechanisms are arranged on the outer wall of the airbag 1; the auxiliary mechanisms include an auxiliary belt 7 and an elastic buckle 71; both ends of the auxiliary belt 7 are fixedly arranged on the outer wall of the airbag 1; the elastic buckle 71 is arranged in the middle of the auxiliary belt 7 for adjusting the tightness.

[0025] The design of the auxiliary belt 7 can improve the stability when pressing the airbag 1. Especially during strenuous exercise or activities, the auxiliary belt 7 can effectively prevent the airbag 1 from slipping or shifting, ensuring that the user can continuously and stably obtain oxygen supply. Through the adjustment of the elastic buckle 71, the user can flexibly adjust the tightness of the auxiliary belt 7 according to personal body shape, comfort requirements and specific activities, and the scope of application is wider.

[0026] The scale lines 63 are marked with different colors.

[0027] By using different colors to mark the scale lines 63, the user can more intuitively understand the range and changes of the air intake. The scale lines 63 of different colors can quickly attract the user's attention and help them quickly and finely control the breathing rhythm and depth.

[0028] like Figure 1 As shown, an air storage valve 8 is provided between the oxygen storage bag 2 and the air bag 1 .

[0029] The rate and amount of oxygen flowing from the oxygen storage bag 2 to the air bag 1 can be adjusted and controlled by providing the gas storage valve 8. This allows the oxygen supply to be accurately adjusted according to the actual needs of the user, avoiding the problem of insufficient or excessive oxygen supply.

[0030] Working principle of the utility model: First, the user connects the external oxygen source to the oxygen storage bag 2 through the oxygen connecting tube 3 to ensure that there is sufficient oxygen supply in the oxygen storage bag 2. An air storage valve 8 is arranged between the oxygen storage bag 2 and the air bag 1, and the air storage valve 8 can adjust and control the rate and amount of oxygen flowing from the oxygen storage bag 2 to the air bag 1, ensuring that the oxygen can flow into the air bag 1 smoothly and continuously. Next, the tightness of the auxiliary belt 7 is adjusted according to the user's body shape and needs, and the auxiliary belt 7 is stably fixed to the user's hand. When the user starts to inhale, by pressing the air bag 1, the oxygen in the air bag 1 is squeezed into the air intake pipe 4 and passes through the pressure safety valve 41. The function of the pressure safety valve 41 is to automatically adjust the pressure to ensure that the pressure inside the respirator is always kept within a safe range. Oxygen is transmitted to the mask 5 for breathing through the pressure safety valve 41. When the oxygen is located in the area between the pressure safety valve 41 and the exhalation valve 42, the pressure sensing head 61 can sense the pressure change in the air intake pipe 4. When the pressure changes, the pressure sensing head 61 drives the mercury in the mercury tube 62 to move, thereby forming a corresponding change in the display 6. The user can judge the current intake volume by observing the position of the mercury in the display 6 and the scale line 63. When the user exhales, the gas is discharged through the exhalation valve 42 and discharged into the external environment through the exhaust port on the mask 5.

[0031] The above embodiments are only used to illustrate the technical method of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical method of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the utility model.
