The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art according to the specific circumstances.
Referring to fig. 1 and 2, a watch 100 with a multi-layer structure is provided in a preferred embodiment of the present invention, and a waterproof vapor injection structure 5 is provided on the watch 100 with the multi-layer structure. A moisture proof cavity 30 is provided within the multi-layer structured wristwatch 100. The injection channel 50 of the waterproof vapor injection structure 5 communicates the outside of the multi-layer structure wristwatch 100 with the waterproof vapor chamber 30. The moisture-proof cavity 30 in the multi-layer structure watch 100 can prevent liquid and moisture from entering the inner watch core 900, so as to ensure the normal operation of the watch core 900.

The vapor proof cavity 30 is filled with a liquid (not shown), and the vapor proof cavity 30 is sealed between the first resealing structure 10 and the second resealing structure 20, so that the liquid can be sealed between the first resealing structure 10 and the second resealing structure 20. Preferably, the liquid is water, but may be other liquid which can be fused with water vapor.
The first resealing structure 10 seals the sealing cavity 90 to prevent the liquid in the vapor preventing cavity 30 from entering the sealing cavity 90 to contact with the watch core 900, and the second resealing structure 20 isolates the vapor preventing cavity 30 from the outer side of the multi-layer watch 100, so that the liquid in the vapor preventing cavity 30 can be prevented from leaking. When the multi-layer structure watch 100 is in the water vapor environment, if water vapor passes through the second heavy seal structure 20, the water vapor enters the water vapor prevention cavity 30 to be contacted with the liquid so as to be cooled and fused into the liquid, and then the water vapor can not pass through the first heavy seal structure 10 any more, so that the damage to the internal structure of the watch core 900 in the seal cavity 90 is avoided, and the normal operation of the multi-layer structure watch 100 is ensured.

Further, the injection channel 50 may be provided with a limiting ring groove 501, and when the injection plug 52 moves to the outside of the multi-layer wristwatch 100 so that the first injection sealing ring 541 is located in the limiting ring groove 501, the second injection sealing ring 542 and the injection inlet 520a of the injection runner 520 are located outside the injection channel 50. By using the limiting ring groove 501, the user can sense that the injection plug 52 has moved to a position where the injection operation can be performed, thereby avoiding the injection plug 52 from being completely pulled out.
In the above embodiment, the inner case 1 and the outer case 2 of the multi-layer structure wristwatch 100 are separately detachable components, and as another embodiment, part of the components between the inner case 1 and the outer case 2 may be integrated. For example, the inner mirror 11 of the inner case 1 and the outer mirror 21 of the outer case 2 are integrally formed, so that shielding of gas in the time display area can be avoided, the inner bottom cover 13 of the inner case 1 and the outer bottom cover 23 of the outer case 2 can be integrally formed, and the moisture preventing cavity 30 and the inner case 1 can be sealed together during assembly.
