Description

Technical Field

[0001] This utility model relates to the field of oxygen generation equipment, and in particular to a vehicle-mounted oxygen diffusion structure and automobile. Background Technology

[0002] Existing vehicle-mounted oxygen generators typically supply oxygen by passing air through a molecular sieve, capturing the nitrogen within, and then providing oxygen.

[0003] Existing external vehicle-mounted oxygen generators, such as those disclosed in Chinese patent application CN118991373A, describe "a vehicle-mounted air conditioning device, a vehicle-mounted air conditioning system, and a vehicle. The vehicle-mounted air conditioning device has an air conditioning housing forming a first space and a second space; a temperature regulating device for regulating the temperature of the air supplied to the vehicle cabin; and an oxygen generator for outputting oxygen to the vehicle cabin. The temperature regulating device is located in the first space; the oxygen generator is at least partially located in the second space, or the oxygen generator is connected to the second space; the first space and the second space are connected so that the air regulated by the temperature regulating device and the oxygen output by the oxygen generator are mixed before entering the vehicle cabin." "The air conditioning housing also forms: an oxygen outlet channel for connecting the first space and the second space; and an exhaust gas channel for connecting the second space and the outside of the air conditioning housing." However, in the existing technology, after oxygen enters the car cabin from the air conditioner, it diffuses throughout the vehicle, and the oxygen concentration in the whole vehicle rises very slowly, making it impossible to provide the driver and passengers with a high concentration of oxygen in a timely manner.

[0004] Some existing technologies also use masks connected to oxygen generators to provide oxygen to users, but wearing a mask can greatly affect comfort.

[0005] Therefore, an on-board oxygen diffusion structure and a vehicle are proposed to solve the above-mentioned technical problems. Utility Model Content

[0009] As a further improvement to the above technical solution, it also includes an expansion tube, on which a flexible valve plate is provided, and the bottom end of the expansion tube passes through the flexible valve plate and is detachably connected to the housing; the number of diffusion heads is multiple.

[0010] As a further improvement to the above technical solution, the exhaust port is arranged from the inside to the outside as a first transition zone, a second transition zone, a first diffusion zone, and a second diffusion zone, and the exhaust ports located in the first transition zone, the second transition zone, the first diffusion zone, and the second diffusion zone are respectively a first through hole, a second through hole, a third through hole, and a fourth through hole.

[0011] As a further improvement to the above technical solution, the number of the first through holes is 7-12 and they are evenly distributed in a ring array along a circle with a diameter of 19mm, and the diameter of the first through holes is 0.5-1.5mm.

[0012] As a further improvement to the above technical solution, the number of the second through holes is 7-12 and they are evenly distributed in a ring array along a circle with a diameter of 22-35mm. The diameter of the second through holes is 0.5-1.5mm, and the second through holes are staggered with the first through holes.

[0013] As a further improvement to the above technical solution, the number of the third through holes is 9-14 and they are evenly distributed in a ring array along a circle with a diameter of 31-37mm.

[0016] As a further improvement to the above technical solution, the housing is provided with a boss, the plate is embedded in the housing and abuts against the boss, and the plate is flush with the bottom of the housing.

[0017] An automobile includes an air intake structure mounted on the A-pillar, B-pillar, or C-pillar of the automobile; an oxygen generator mounted on the automobile and located outside the passenger compartment; and a diffusion head mounted inside the passenger compartment and located on the top and side of the interior trim of the automobile.

[0018] The beneficial effects of this utility model are: By setting up an air intake structure, the oxygen generator draws air from outside the car; the oxygen generator then produces oxygen and releases it to the user through a diffuser, allowing the user to directly obtain a high concentration of oxygen without needing to wear a mask, thus providing the benefits of effective and comfortable oxygen supply.
