DETAILED DESCRIPTION

In order to make the purpose, technical scheme and advantages of the embodiment of the utility model clearer, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

As shown in Figures 1-4, an air intake structure includes: a transverse pipe 1, wherein the middle part of the transverse pipe 1 has a relatively independent first air duct 3 and a second air duct 4, the first air duct 3 and the second air duct 4 are respectively connected to a first external air pipe connecting part 7 and a second external air pipe connecting part 8, a second air outlet nozzle 6 is arranged on one side of the transverse pipe 1, the second air outlet nozzle 6 is connected to the second air duct 4, the first air duct 3 is connected to a first air outlet nozzle 5, the first air outlet nozzle 5 is located inside the second air outlet nozzle 6, and a ventilation gap is provided between the second air outlet nozzle 6 and the first air outlet nozzle 5.

It should be noted that the first air channel 3 and the second air channel 4 have the same size, which is equivalent to inserting a small tube in the transverse tube 1 and dividing the small tube into two independent parts along the vertical plane, thereby dividing the transverse tube 1 into two independent spaces. The second air outlet nozzle 6 and the first air outlet nozzle 5 are independently connected to the two cavities, and the first air channel 3 and the second air channel 4 are respectively connected to the first external air pipe connection part 7 and the second external air pipe connection part 8, so that two air sources can be independently supplied; it can also be achieved that air is taken in and air is discharged at the same time.

As a preferred embodiment, the height of the first air outlet nozzle 5 is higher than that of the second air outlet nozzle 6, so that a relatively independent effect can be achieved in the case of mixed air supply.

As a preferred embodiment, the axes of the first air outlet nozzle 5 and the second air outlet nozzle 6 are perpendicular to the axis of the cross pipe 1 .

It should be noted that, usually, the first air channel 3 and the second air channel 4 are symmetrically arranged in parallel, and the first air outlet nozzle 5 and the second air outlet nozzle 6 are connected to the top of the first air channel 3 and the second air channel 4 .

As a preferred embodiment, the number of the first air outlet nozzles 5 and the number of the second air outlet nozzles 6 are both two.

A method for using an inhalation structure, wherein the first external air tube connection part 7 is connected to an oxygen storage device, the first air outlet nozzle 5 and the second air outlet nozzle 6 are placed in the user's nasal cavity, and a negative pressure sensor is arranged in the second external air tube connection part 8. When the negative pressure sensor reaches a set threshold, the oxygen storage device starts to supply air.

It should be noted that this method of use changes the breathing strength of the user, such as sudden inhalation, which indicates that the user is suffering from hypoxia, and the negative pressure generated on the second air outlet 6 increases, which is detected by the negative pressure sensor, and then controls the oxygen storage device to supply air, so that oxygen reaches the first air outlet 5, allowing the user to inhale oxygen.

A method for using an inhalation structure, wherein the first external air pipe connection part 7 is connected to an oxygen storage device, the first air outlet nozzle 5 and the second air outlet nozzle 6 are placed in the user's nasal cavity, the second external air pipe connection part 8 is connected to a hydrogen storage device, and the ventilation volume of oxygen and hydrogen is controlled by a control valve.

It should be noted that when mixed gas inhalation is required, different gas sources, such as oxygen and hydrogen, are connected to the first external air pipe connection part 7 and the second external air pipe connection part 8, so that two gas sources are provided at the first air outlet 5 and the second air outlet 6 for the user to inhale. Of course, this kind of mixing needs to control its mixing ratio within a safe range.
