[0002] Nowadays, people in society pay more and more attention to health and wellness, and micro-hyperbaric oxygen chambers have entered the public's view to meet people's needs. Especially in recent years, the micro-hyperbaric oxygen chamber industry has developed rapidly. In order to provide consumers with a more comfortable experience, oxygen chamber manufacturers usually install air conditioners inside the chamber to make the internal environment of the chamber more comfortable. However, the air pressure inside the chamber poses great difficulties for the installation of the air conditioner. The inside of the chamber needs to be sealed, resulting in the air conditioner pipes being divided into two sections, inside and outside the chamber. The filling of the refrigerant requires evacuating the air conditioner pipes, so the installation of the air conditioner can only be carried out on-site at the customer's location, which greatly wastes human and material resources. On-site installation and debugging increase the unstable factors of equipment operation.

[0021] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0022] In one embodiment, Figures 1-6As shown in the figure, an oxygen chamber through-cabin internal and external sealing joint includes an external machine sealing joint and an internal machine sealing joint: The external machine sealing joint includes an external valve body 2, and a sealing component is arranged inside the external valve body 2; The internal machine sealing joint includes an internal valve body 9, and a valve core component is arranged inside the internal valve body 9. The external valve body 2 is connected to the internal valve body 9 through the sealing component. By setting the external machine sealing joint and the internal machine sealing joint, the two ends inside and outside the cabin body 8 can be better sealed.

[0023] In one embodiment, as Figure 1 and Figure 3 shown, a thimble 1 is connected to the external valve body 2 by internal threads. A soft silicone 3 is fixed on the lower end face of the thimble 1, so that the thimble 1 moves to the left, and drives the soft silicone 3 to seal the outlet of the external valve body 2, avoiding the leakage of the refrigerant inside the air-conditioning pipe; An air inlet end 17 is also opened at the lower end of the external valve body 2.

[0024] In one embodiment, as Figure 3 shown, the sealing component includes a snap ring 4, a lock nut 5 and an O-ring 6; The lock nut 5 sleeved on the outside of the external valve body 2, and the upper end of the lock nut 5 is fastened to the external valve body 2 through the O-ring 6; A snap ring 4 is arranged on the inner side of the lower end of the lock nut 5, and the connection and fixation between the internal valve body 9 and the external valve body 2 are realized through the lock nut 5.

[0025] In one embodiment, as Figure 6 shown, the valve core component includes a valve core 12, a sealing connecting rod 11, a pressure spring 16, a circlip 15, a positioning ring 14 and a soft silicone 3; The valve core 12 is fixedly connected to the inner wall of the internal valve body 9 by threads. A sealing connecting rod 11 is also sleeved inside the valve core 12. A pressure spring 16 is sleeved on the upper end of the sealing connecting rod 11. A circlip 15 is arranged below the pressure spring 16. A positioning ring 14 is arranged below the circlip 15. The soft silicone 3 is fixed on the lower end face of the sealing connecting rod 11. The pressure of the pressure spring 16 makes the sealing connecting rod 11 move to the left, and further makes the soft silicone 3 tightly seal the air outlet end 10 on the right side of the valve core 12; The size of the sealing connecting rod 11 also matches the size of the air outlet end 10.

[0026] In one embodiment, as Figure 5 and Figure 6 shown, both the circlip 15 and the positioning ring 14 are sleeved on the sealing connecting rod 11; The positioning ring 14 is also embedded inside the internal valve body 9 to provide a supporting force for the pressure spring 16.

[0027] In one embodiment, as Figure 1 and Figure 4As shown, the left end of the inner valve body 9 is connected to the cabin body 8, and silicone pads 7 and nuts 13 are respectively arranged at both ends of the cabin body 8, and the sealing of the inside and outside of the cabin body 8 is achieved by the silicone pads 7 on both sides of the cabin body 8; an air outlet 10 is arranged on the right side of the inner valve body 9. When the air conditioner is working, the refrigerant liquid enters the air inlet end of the external machine sealing joint through the air conditioning pipe and enters the interior of the oxygen cabin through the air outlet end of the internal machine sealing joint.

[0028] In one embodiment, Figure 1 As shown, the ejector pin 1 and the sealing connecting rod 11 cooperate with each other. After the air conditioner indoor unit sealing joint and the air conditioner outdoor unit sealing joint are connected, the sealing connecting rod 11 is pushed rightward by rotating the ejector pin 1 to achieve the connection between the air inlet end and the air outlet end.

[0029] Working principle: When sealing is required, the oxygen chamber manufacturer can add refrigerant to the production line, rotate the ejector pin 1 to move to the left, and drive the soft silicone 3 to seal the outlet of the outer valve body 2 to prevent the refrigerant inside the air-conditioning pipe from leaking out; after the above functions are completed, the inner and outer units are disassembled for separate packaging and shipment. When the joints are connected at the customer's site, the sealing connecting rod 11 is pushed to the right by rotating the ejector pin 1 to achieve the connection between the air inlet and the air outlet. The refrigerant liquid enters the air inlet of the external unit sealing joint through the air-conditioning pipe, and enters the oxygen chamber through the air outlet of the internal unit sealing joint.

[0030] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
