Description

Technical Field

[0001] The utility model belongs to the technical field of oxygen chamber accessories, and in particular relates to an air conditioning structure suitable for an oxygen chamber. Background Art

[0002] When the oxygen chamber is in use, compressed air is filled into the chamber, making the environment inside the chamber higher than the atmospheric pressure outside the chamber. The user breathes in a sitting position in the chamber, and each use of the chamber generally lasts 60-150 minutes. When the oxygen chamber is in operation, the increase in the air pressure in the chamber will cause the ambient temperature inside the chamber to rise, and when the pressure is reduced, the ambient temperature inside the chamber will decrease due to the decrease in air pressure. The air conditioner can effectively control the air temperature and humidity in the oxygen chamber through the principles of condensation and evaporation, so that the internal environment is kept within a comfortable range. Therefore, installing an air conditioner in the oxygen chamber can improve the comfort of the user and is an important component structure of the oxygen chamber.

[0003] Due to the special environment in the oxygen chamber, the safety requirements for air conditioners are extremely high. In the prior art, the air supply motors of air conditioners are all 220V AC motors or 310V high-voltage DC motors, and there are no air conditioners that meet the oxygen chamber standards (the oxygen chamber standards require that the voltage entering the chamber should not be higher than 24V). In the prior art, there are also cases where household air conditioners are forcibly installed in oxygen chambers. This operation will cause the motor to generate sparks, thereby increasing the risk factor of using the oxygen chamber. At the same time, high voltage entering the oxygen chamber will increase the risk of electric shock and fire.

[0004] The motor is the core component of the oxygen cabin air conditioning structure. The high oxygen environment in the oxygen cabin may cause oxidation to the motor components, accelerating their aging and damage. At the same time, the direct connection of the motor to the air conditioning rotating device will also shorten the service life of the motor.

[0005] Therefore, the safety and service life of oxygen chamber air conditioners in the prior art are issues that need to be addressed. Utility Model Content

[0007] The motor comprises a motor shaft, which is connected to the air conditioner impeller via a driven shaft; two magnetic couplings are arranged at the connection between the motor shaft and the driven shaft, and a sleeve cover is arranged between the two magnetic couplings; a sleeve is arranged outside the magnetic coupling close to one side of the motor shaft; the sleeve passes through the oxygen cabin wall; and the sleeve cover is fixedly connected to the sleeve;

[0008] The external unit is connected to the heat sink through a refrigerant pipe; the heat sink is arranged below the air conditioner fan wheel, and there is a gap between the heat sink and the air conditioner fan wheel; the external unit is arranged outside the oxygen cabin.

[0013] Beneficial effects of the utility model:

The motor works outside the cabin to drive the air-conditioning fan wheel in the cabin to rotate, thereby eliminating the risk of electric shock and spark fire caused by the power supply entering the cabin.

[0021] The indoor unit 13 is also provided with a drain pipe 14 , which is led out from the indoor unit 13 .

[0022] The air conditioning structure of the oxygen cabin of the present invention also includes a heat sink 9, which is arranged below the air conditioning wind wheel 8, and there is a gap between the heat sink 9 and the air conditioning wind wheel 8; the gap is set here in order not to affect the rotation of the air conditioning wind wheel 8; the heat sink 9 is connected to the external unit 11 through the refrigerant pipe 10; the external unit 11 is arranged on the outside of the oxygen cabin.

[0023] The external unit 11 delivers cold or hot medium to the heat sink 9 through the refrigerant pipe 10. The delivered medium may be cold air or hot air, cold water or hot water, or refrigerant.

[0024] Specifically, the motor 6 is fixed on the outer wall of the oxygen chamber through the motor bracket 7. The motor bracket 7 is fixed on the outer body of the oxygen chamber. In this way, the motor 6 is stably arranged on the outer wall of the oxygen chamber.

[0025] Specifically, the sleeve 3 and the sleeve cover plate 12 are made of austenitic stainless steel. The sleeve 3 is welded to the oxygen chamber wall.

[0026] Specifically, the air conditioning structure of the oxygen cabin also includes a bearing seat 4, a fixing plate 2, a stabilizing plate 17, and a connecting rod 19. The driven shaft 1 is connected to the fixing plate 2 through the bearing seat 4. A stabilizing plate 17 is provided on one side of the fixing plate 2.
