Description

Technical Field

[0001] This utility model relates to the field of vehicle-mounted oxygen generation equipment, and in particular to an oxygen diffusion structure. 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 above technology, after oxygen enters the car through the air conditioner, it is quickly dispersed throughout the entire vehicle space. For passengers, the increase in oxygen concentration in the air is very slow. Furthermore, to ensure safety, the oxygen concentration inside the car cannot exceed 20%, otherwise the vehicle body will become highly flammable.

[0004] Other existing technologies, such as the use of oxygen masks, enable users to obtain higher concentrations of oxygen more quickly. For example, patent application CN115317820A discloses "a vehicle-mounted oxygen supply and rescue device and a vehicle. The vehicle-mounted oxygen supply and rescue device includes an oxygen tank, an oxygen delivery tube, a cable, and a mask. The oxygen tank is equipped with a stop valve for limiting and stopping the output of oxygen. The oxygen delivery tube is connected to the stop valve and is equipped with a pressure-reducing valve for adjusting the output oxygen to a pressure and rate suitable for human breathing." The aforementioned existing technology allows users to obtain a higher concentration of oxygen relatively quickly, but users need to wear a mask on their face, which is uncomfortable when traveling.

[0005] To address this technical problem, an oxygen dispersion structure is proposed. Utility Model Content

[0006] To solve the above-mentioned technical problems, the purpose of this utility model is to provide an oxygen diffusion structure that has the advantage of maintaining oxygen concentration within a set diffusion area, and the user does not need to wear a mask, thus not affecting comfort.

[0007] The technical solution adopted by this utility model to solve the problem is: The housing has an inner cavity and a plug-in portion. An inner tube is detachably connected to the plug-in portion, and the bottom end of the plug-in portion communicates with the inner cavity. A diffusion plate is sealed to the bottom of the housing. A flexible valve plate is provided on the diffusion plate, and the bottom end of the inner tube passes through the flexible valve plate. A diffusion hole is provided on the diffusion plate.

[0008] As a further improvement to the above technical solution, the side wall of the plug portion is provided with a through hole communicating with the inner cavity, and the side wall of the inner pipe can block the through hole.

[0009] As a further improvement to the above technical solution, the number of the first through holes is 8-10 and they are uniformly distributed in a ring array along a circle with a diameter of 17-20.5-2mm, and the diameter of the first through holes is 0.5-2mm.

[0010] As a further improvement to the above technical solution, the number of the second through holes is 8-10 and they are evenly distributed in a ring array along a circle with a diameter of 25-33mm. The diameter of the second through holes is 0.5-2mm, and the second through holes are staggered with the first through holes.

[0011] As a further improvement to the above technical solution, the number of the third through holes is 8-15 and they are evenly distributed in a ring array along a circle with a diameter of 30-38mm. The diameter of the third through holes is 0.5-2mm, and the third through holes are staggered with the second through holes.

[0012] As a further improvement to the above technical solution, the number of the fourth through holes is 12 and they are evenly distributed in a ring array along a circle with a diameter of 35-48mm. The diameter of the fourth through holes is 0.5-2mm, and the fourth through holes are staggered with the third through holes.

[0013] As a further improvement to the above technical solution, the first and second through holes are inclined outward at 8-13 degrees, and the third and fourth through holes are inclined outward at 15-26 degrees.

[0014] As a further improvement to the above technical solution, the housing is provided with a boss, and a dispersion plate is embedded in the housing and abuts against the boss. The dispersion plate is flush with the bottom of the housing.

[0015] As a further improvement to the above technical solution, a flexible valve plate is provided inside the inner pipe.

[0016] The beneficial effects of this utility model are: This oxygen diffusion structure is used for installation on vehicles to supply oxygen to the inner cavity of the housing via an oxygen generating device in the prior art, such as connecting the connector to an external oxygen generating device via a pipeline.

[0017] Oxygen is obtained through this oxygen diffusion structure, and users do not need to wear a mask, so it does not affect comfort. Furthermore, by setting up an internal tube, an external mask can be connected, thus retaining the function of providing oxygen to the user through the mask, and oxygen can also be obtained through the mask when needed.

[0025] Reference Figures 1 to 3 An oxygen diffusion structure includes: a housing 1 having an inner cavity, a plug-in portion 11 on the housing 1, an inner tube 4 detachably connected to the plug-in portion 11, the bottom end of the plug-in portion 11 communicating with the inner cavity; a diffusion plate 2 sealed to the bottom of the housing 1, a flexible valve plate 41 on the diffusion plate 2, the bottom end of the inner tube 4 penetrating the flexible valve plate 41, and a diffusion hole 3 on the diffusion plate 2.

[0026] The flexible valve plate can be made of relatively soft polymer materials such as rubber, silicone, and TPU, and is used to seal the diffusion plate 2 when the inner pipe 4 is not connected.

[0027] When the vehicle leaves the factory, the oxygen diffusion structure is installed in the car cabin, such as in the roof, doors, seats, etc., and oxygen is supplied to the inner cavity of the shell 1 through the oxygen generation equipment in the car.

[0028] When the external mask is not in use, the inner tube 4 can be removed, and oxygen can be diffused through the diffusion plate 2. The user can directly inhale the oxygen diffused by the nearby oxygen diffusion structure.

[0029] When an external mask is needed, the inner tube 4 is passed through the flexible valve plate 41 and connected to the plug part 11 to obtain oxygen through the mask.

[0030] In a preferred embodiment, the side wall of the insertion part 11 is provided with a through hole 111 communicating with the inner cavity, and the side wall of the inner tube 4 can block the through hole 111. This prevents oxygen from diffusing from the oxygen diffusion structure when using the mask.

[0031] In a preferred embodiment, the diffusion holes 3 are arranged from the inside to the outside as a first transition zone 31, a second transition zone 32, a first diffusion zone 33, and a second diffusion zone 34. The diffusion holes 3 located in the first transition zone 31, the second transition zone 32, the first diffusion zone 33, and the second diffusion zone 34 are respectively a first through hole 311, a second through hole 321, a third through hole 331, and a fourth through hole 341.

[0032] In a preferred embodiment, there are 8-10 first through holes 311, which are uniformly distributed in a ring array along a circle with a diameter of 17-20.5-2 mm, and the diameter of the first through holes 311 is 0.5-2 mm.

[0033] In a preferred embodiment, there are 8-10 second through holes 321, which are uniformly distributed in a ring array along a circle with a diameter of 25-33 mm. The diameter of the second through holes 321 is 0.5-2 mm, and the second through holes 321 and the first through holes 311 are staggered.

[0034] In a preferred embodiment, there are 8-15 third through holes 331, which are uniformly distributed in a ring array along a circle with a diameter of 30-38 mm. The diameter of the third through holes 331 is 0.5-2 mm, and the third through holes 331 and the second through holes 321 are staggered.

[0035] In a preferred embodiment, there are 12 fourth through holes 341, which are uniformly distributed in a ring array along a circle with a diameter of 35-48 mm. The diameter of the fourth through holes 341 is 0.5-2 mm, and the fourth through holes 341 and the third through holes 331 are staggered.

[0036] In a preferred embodiment, the first through hole 311 and the second through hole 321 are inclined outward at 8-13 degrees, and the third through hole 331 and the fourth through hole 341 are inclined outward at 15-26 degrees.

[0037] In a preferred embodiment, the housing 1 is provided with a boss 12, and the dispersion plate 2 is embedded in the housing 1 and abuts against the boss 12. The dispersion plate 2 is flush with the bottom of the housing 1.

[0038] like Figure 4 As shown, the area marked by the dashed line below the shell 1 is the diffusion zone. A coordinate axis is set in the diffusion zone and the oxygen concentration is detected. The detection results show that point A (0,0) has an oxygen concentration of 95%, point B (0,180mm) has an oxygen concentration of 51%, point C (0,300mm) has an oxygen concentration of 27.1%, and point D (40mm,300mm) has an oxygen concentration of 23.4%. Therefore, the oxygen concentration can be maintained at 23%-25% at the outermost plane of the diffusion zone.

[0039] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
