[0019] Embodiment: As Figure 1-6 shown, the present utility model provides a dry fan coil, including a copper tube 4. Both ends of the copper tube 4 are fixedly connected with convex tubes 5. The side wall of the convex tube 5 is fixedly sleeved with a first convex disk 6. The side of the convex tube 5 facing away from the copper tube 4 is detachably provided with an elbow 10. The side wall of the elbow 10 is fixedly sleeved with a second convex disk 11. The second convex disk 11 corresponds to the first convex disk 6, and a sealing ring 9 is arranged between the second convex disk 11 and the first convex disk 6.

[0020] The size of the second convex disk 11 is larger than that of the first convex disk 6, and an external thread 7 is arranged on the outer side wall of the first convex disk 6.

[0021] By adopting the above technical solution, when the copper pipe 4 needs to be installed, the first convex disk 6 is aligned with the second convex disk 11, and the axis of the first convex disk 6 is collinear with the axis of the second convex disk 11. The sealing ring 9 is placed in the first sealing groove 8 and the second sealing groove 13. Then, the housing 14 is screwed. Through the mutual cooperation of the internal thread 16 and the external thread 7, the housing 14 can be fixed to the first convex disk 6, so as to press and fix the sealing ring 9, and further make the connection between the copper pipe 4 and the elbow 10 in a sealed state, avoiding leakage.

[0022] A first sealing groove 8 is arranged on the surface of the first convex disk 6 facing the second convex disk 11, and a second sealing groove 13 is arranged on the surface of the second convex disk 11 facing the first convex disk 6. The first sealing groove 8 corresponds to the second sealing groove 13 and has the same diameter. The sealing ring 9 corresponds to and cooperates with the first sealing groove 8 and the second sealing groove 13.

[0023] By adopting the above technical solution, during installation and use, the sealing ring 9 needs to be located in the first sealing groove 8 and the second sealing groove 13. When the housing 14 is screwed, through the mutual cooperation of the internal thread 16 and the external thread 7, the housing 14 can be fixed to the first convex disk 6, so as to press and fix the sealing ring 9, and further make the connection between the copper pipe 4 and the elbow 10 in a sealed state.

[0024] A housing 14 is sleeved on the side wall of the elbow 10. The housing 14 includes a housing opening 15. The second convex disk 11 is located in the housing opening 15. A rubber ring 12 is fixedly connected to the outer side wall of the second convex disk 11. The rubber ring 12 is located in the housing opening 15. An internal thread 16 is arranged on the inner side wall of the housing 14. The internal thread 16 corresponds to and cooperates with the external thread 7. A through opening is arranged through the side wall of the housing 14. The elbow 10 is located in the through opening, and the elbow 10 cooperates with the through opening.

[0025] By adopting the above technical solution, the housing 14 is arc-shaped near the through opening. After the internal thread 16 and the external thread 7 are fully engaged, the rubber ring 12 will be in the arc-shaped area of the housing 14. At this time, the rubber ring 12 is in close contact with the inner wall of the housing 14, thus preventing foreign substances from entering the connection between the copper pipe 4 and the elbow 10 through the through opening.

[0026] Chambers 1 are arranged on both sides of the copper pipe 4. A chamber opening 2 is arranged through the side wall of the chamber 1. A switchable cover 3 is detachably arranged at the opening of the chamber opening 2. The elbow 10 is located in the chamber opening 2.

[0027] By adopting the above technical solution, when the copper pipe 4 is damaged and needs to be replaced, the switchable cover 3 is removed, and the elbow 10 can be operated at the chamber opening 2 to disassemble and replace the copper pipe 4.

[0028] Working principle: When in use, when the copper pipe 4 needs to be installed, the first convex disk 6 is made to correspond to the second convex disk 11, and the axis of the first convex disk 6 is made to be collinear with the axis of the second convex disk 11, and the sealing ring 9 is placed in the first sealing groove 8 and the second sealing groove 13;

[0029] Then, turn the housing 14. Through the mutual cooperation of the internal thread 16 and the external thread 7, the housing 14 can be fixed to the first convex disk 6, so as to press and fix the sealing ring 9, and further make the connection between the copper pipe 4 and the elbow 10 in a sealed state, avoiding leakage;

[0030] And after the internal thread 16 and the external thread 7 are fully matched, the rubber ring 12 will be in the arc-shaped area of the housing 14. At this time, the rubber ring 12 is in close contact with the inner wall of the housing 14, so as to prevent external sundries from entering the connection between the copper pipe 4 and the elbow 10 through the through port;

[0031] When the copper pipe 4 is damaged and needs to be replaced, remove the opening and closing cover 3 and loosen the housing 14, then the copper pipe 4 can be disassembled and replaced.

[0032] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and its equivalent technologies, the present invention is also intended to include these modifications and variations.
