Referring to fig. 1 and 2, a multilayer watch 100 is provided according to a preferred embodiment of the present invention, in which a pressure relief protection structure 6 is disposed on the multilayer watch 100. As shown in fig. 3 and 4, the multilayer wristwatch 100 has a vapor-proof chamber 30. The pressure relief passage 60 of the pressure relief protection structure 6 communicates the outside of the multilayer watch 100 with the moisture-proof chamber 30. The vapor-proof chamber 30 in the multilayer watch 100 can prevent liquid and vapor from entering the watch core 900 inside, so as to ensure the normal operation of the watch core 900.
As shown in fig. 3, the multilayer wristwatch 100 is provided with a seal chamber 90, a first reseal structure 10, a moisture-proof chamber 30, and a second reseal structure 20 in this order from the inside to the outside. The seal cavity 90 is used for accommodating the watch core 900, and the seal cavity 90 is sealed in the first reseal structure 10. The moisture-proof chamber 30 is filled with a liquid (not shown), and the moisture-proof chamber 30 is sealed between the first and second resealing structures 10 and 20, and thus the liquid can be sealed between the first and second resealing structures 10 and 20. Preferably, the liquid is water, but of course, other liquids that can fuse with water vapor are possible.
The first reseal structure 10 seals the sealing chamber 90 to prevent the liquid in the moisture-proof chamber 30 from entering the sealing chamber 90 and contacting the watch core 900, and the second reseal structure 20 isolates the moisture-proof chamber 30 from the outside of the multilayer structure watch 100 to prevent the liquid in the moisture-proof chamber 30 from leaking. When multilayer structure wrist-watch 100 is in the steam environment, if steam is through second heavy seal structure 20, steam will get into and go in steam-proof chamber 30 and the contact of liquid and then the cooling fuses to liquid, and then can not rethread first heavy seal structure 10, has avoided steam to get into and has caused the harm to the refill 900 inner structure in sealed chamber 90, guarantees multilayer structure wrist-watch 100's normal operating.
In the present embodiment, as shown in fig. 3, the multilayer wristwatch 100 includes an inner case 1 and an outer case 2; the inner shell 1 is arranged in the outer shell 2; the first reseal structure 10 is disposed on the inner case 1 and seals the seal cavity 90 and the watch core 900 in the inner case 1; the second reseal structure 20 is disposed on the outer shell 2 and seals the inner shell 1 within the outer shell 2 with the moisture proof chamber 30 located between the inner shell 1 and the outer shell 2. By providing the first and second reseal structures 10 and 20 on the inner case 1 and the outer case 2, respectively, relative independence of the first and second reseal structures 10 and 20 can be achieved, and assembly and disassembly can be performed, respectively, to avoid liquid in the vapor-proof chamber 30 from contacting the watch core 900 during disassembly and assembly. When the watch core is detached, the outer shell 2 is firstly opened to expose the waterproof vapor cavity 30, liquid in the waterproof vapor cavity is discharged completely, and then the inner shell 1 is opened to maintain the watch core 900, so that the watch core 900 is completely prevented from contacting the liquid.
As shown in fig. 5, 6 and 7, the watch case 100 is provided with a pressure relief protection structure 6, the pressure relief protection structure 6 includes a pressure relief channel 60, a pressure relief piece 61 and a pressure relief elastic piece 62, the pressure relief channel 60 communicates between the inside and outside of the watch with a multilayer structure, more specifically, the pressure relief channel 60 communicates between the outside of the watch case 100 and a water vapor proof cavity 30 in the watch case 100; the pressure relief piece 61 is slidably engaged with the pressure relief passage 60 in a direction of an axial direction of the pressure relief passage 60, so that the pressure relief piece 61 is moved between a sealing position and a pressure relief position, the sealing position is close to the vapor-proof chamber 30 inside the watch with a multi-layer structure relative to the pressure relief position, that is, the pressure relief piece 61 is moved close to or away from the vapor-proof chamber 30 inside the watch case 100. A pressure relief elastic member 62 is connected between the pressure relief member 61 and the pressure relief passage 60 for providing a force to the pressure relief member 61 to move toward the waterproof vapor chamber 30.
When the pressure relief member 61 is in the sealing position, as shown in fig. 7, the pressure relief member 61 is in sealing engagement with the pressure relief passage 60, and the pressure relief protection structure 6 is in a sealing state.
Under the condition that the pressure in the waterproof steam chamber 30 is too large, the pressure relief piece 61 can move towards the pressure relief position against the action force of the pressure relief elastic piece under the action of the internal pressure of the waterproof steam chamber 30, as shown in fig. 8, when the pressure relief piece 61 moves to the pressure relief position, the pressure relief piece 61 is in clearance fit with the pressure relief channel 60, the waterproof steam chamber 30 and the outer side of the multilayer watch 100 are in a communicated state to release the pressure in the waterproof steam chamber 30, and the pressure relief elastic piece 62 is in an elastic deformation state and can provide the action force moving towards the sealing position for the pressure relief piece 61. The sealed position is close to the inner side of the multilayer structure wristwatch 100, i.e., close to the moisture-proof chamber 30, with respect to the pressure release position.

The space within the pressure relief tube 63 forms the pressure relief passage 60. The pressure release channel 60 is formed by the pressure release pipe 63, so that the machining precision requirement on the pressure release through hole 106 can be reduced, and the aperture of the pressure release through hole 106 can be set to be relatively large, so as to facilitate machining and forming. Here, in other embodiments, the pressure relief passage 60 may be formed directly through the pressure relief through hole 106 without providing the pressure relief tube 63.
As shown in fig. 6, the pressure relief pipe 63 includes a first pressure relief pipe 631 and a second pressure relief pipe 632 coaxially disposed, the second pressure relief pipe 632 is close to the steam-proof cavity 30 relative to the first pressure relief pipe 631, the outer diameter of the first pressure relief pipe 631 is larger than the outer diameter of the second pressure relief pipe 632, and the outer walls of the first pressure relief pipe 631 and the second pressure relief pipe 632 are transited by an inclined surface. The first pressure relief pipe 631 is in interference fit with the pressure relief through hole 106, and the second pressure relief pipe 632 is in clearance fit with the pressure relief through hole 106. First, the second pressure release pipe 632 is inserted into the pressure release through hole 106, and then the first pressure release pipe 631 is inserted into the pressure release through hole 106 through the inclined surface, thereby facilitating the assembly of the pressure release pipe 63 into the pressure release through hole 106.
The pressure relief pipe 63 further comprises a pressure relief check ring 633, the pressure relief check ring 633 is coaxially arranged with the first pressure relief pipe 631 and the second pressure relief pipe 632, and the first pressure relief pipe 631 is connected between the pressure relief check ring 633 and the second pressure relief pipe 632. The outer diameter of the pressure relief check ring 633 is larger than that of the first pressure relief pipe 631, and a pressure relief outer step is formed between the outer peripheral surfaces of the pressure relief check ring 633 and the first pressure relief pipe 631. When assembling the pressure release pipe 63, the outer step of pressure release formed by the pressure release check ring 633 can be blocked at the outer edge of the pressure release through hole 106, the depth of the pressure release pipe 63 inserted into the housing 2 of the multilayer watch can be limited, and meanwhile, the pressure release pipe 63 can be ensured to be assembled in place.
In this embodiment, as shown in fig. 6 and 7, the pressure releasing element 61 includes a pressure releasing pillar 611 and a pressure releasing crown 612, the pressure releasing pillar 611 is slidably disposed in the pressure releasing channel 60 along the axial direction of the pressure releasing channel 60, the pressure releasing pillar 611 has an inner pressure releasing end 611b and an outer pressure releasing end 611a opposite to each other, the inner pressure releasing end 611b is close to the steam-proof cavity 30 inside the multilayer watch 100 opposite to the outer pressure releasing end 611a, the inner pressure releasing end 611b is connected to the pressure releasing elastic element 62, and the pressure releasing crown 612 is located at the outer pressure releasing end 611 a.

The pressure relief post 611 and/or the pressure relief crown 612 can be in sealing engagement with the pressure relief channel 60, in this embodiment, the pressure relief crown 612 is in sealing engagement with the pressure relief channel 60 to seal the pressure relief post 611 within the pressure relief channel 60.
The edge of the inner pressure relief end 611b is provided with a first limiting portion 6111, the inner wall of the pressure relief channel 60 is provided with a second limiting portion 6011, and the pressure relief elastic member 62 is a pressure spring, is sleeved on the pressure relief column 611, and is located between the first limiting portion 6111 and the second limiting portion 6011. When the pressure relief pillar 611 moves toward the outside of the multi-layer wristwatch 100, the first stopper 6111 and the second stopper 6011 move closer to each other, so that the elastic member is compressed, and the elastic member can provide a force to the pressure relief pillar 611 to move toward the inside of the waterproof vapor chamber 30. By the mutual cooperation of the first limiting portion 6111, the second limiting portion 6011 and the pressure relief elastic member 62, the pressure relief protection structure 6 can automatically recover to a sealed state after a proper pressure relief, and the pressure relief column 611 can be prevented from being released from the pressure relief channel 60.

With the threads between the pressure relief crown 612 and the entrance to the pressure relief channel 60, the pressure relief piece 61 can only be moved within the pressure relief channel 60 by rotating the pressure relief crown 612 under the influence of an external force.
As shown in fig. 8, when the pressure relief crown 612 is separated from the thread at the inlet of the pressure relief channel 60, i.e. the pressure relief crown 612 is in the unscrewed state, the whole pressure relief piece 61 can move in the pressure relief channel 60 to open or seal the pressure relief channel 60.
The pressure relief cap 612 can limit the movement of the pressure relief column 611, so that the user can rotate the pressure relief cap 612 to relieve pressure when the pressure is required to be relieved, thereby avoiding automatic pressure relief under unnecessary conditions.

By the sealing structure of the central pillar 6123 and the pressure relief channel 60, the sealing between the pressure relief piece 61 and the pressure relief channel 60 can be realized, and the pressure relief pillar 611 is sealed in the pressure relief channel 60.
A pressure relief sealing ring 602 is arranged in the pressure relief passage 60. Specifically, the inner wall of the pressure relief channel 60 is provided with a pressure relief ring groove 601, a pressure relief sealing ring 602 is arranged in the pressure relief ring groove 601, the pressure relief sealing ring 602 can be positioned on the inner wall of the pressure relief channel 60 through the pressure relief ring groove 601, and when the pressure relief piece 61 moves, the pressure relief sealing ring 602 cannot be driven to move. The pressure relief sealing ring 602 is connected to the outer wall of the central column 6123, so as to realize the sealing connection between the pressure relief crown 612 and the pressure relief channel 60.

The second embodiment of the present invention provides a pressure relief protection structure and a corresponding multi-layer watch, which are different from the previous embodiments in the structure of the pressure relief protection structure 6. As shown in fig. 10 and 11, in the present embodiment, in the pressure relief protection structure 6, the pressure relief element 61 includes a pressure relief pillar 611 and a pressure relief crown 612, and the pressure relief pillar 611 and the pressure relief crown 612 are two separable independent components, i.e. they are not connected to form an integral structure. The pressure relief post 611 and the pressure relief tube 63 may each provide a sealing structure with the pressure relief passage 60, or one of them may provide a sealing structure with the pressure relief passage 60.
Compared with the previous embodiments, the pressure relief crown 612 in this embodiment is different only in the matching structure between the connecting tube 6123 and the pressure relief pillar 611, and the structure is the same, and therefore, the description thereof is omitted.
More specifically, a first sealing ring 661 is disposed between the central pillar 6123 of the pressure relief crown 612 and the pressure relief channel 60, and a second sealing ring 662 is disposed between the first limiting portion 6111 of the pressure relief pillar 611 and the pressure relief channel 60. In this embodiment, the first and second seal rings 661 and 662 are positioned on the inner wall of the pressure relief passage 60, and when the pressure relief member 61, i.e., the pressure relief post 611 and the pressure relief crown 612, moves along the pressure relief passage 60, they can contact or be in clearance fit with the second seal ring 662 and the first seal ring 661, thereby achieving the switching between the sealed state and the open state. Here, depending on the structure of the relief crown 612 and the relief post 611, the first seal 661 and the second seal 662 of the seal structure may be provided at other portions of the relief crown 612 and the relief post 611.
In this embodiment, when the pressure relief protection structure 6 is in a sealed state, the pressure relief crown 612 is screwed at the opening of the pressure relief channel 60, the peripheral surface of the central column 6123 of the pressure relief crown 612 contacts and cooperates with the first sealing ring 661, and the pressure relief column 611 contacts and cooperates with the second sealing ring 662, so that the pressure relief piece 61 and the pressure relief channel 60 are in a sealed and cooperating state. And the pressure relief crown 612 is stopped at the pressure relief outer end 611a of the pressure relief pillar 611 to limit the movement of the pressure relief pillar 611, so that both the pressure relief pillar 611 and the pressure relief crown 612 and the pressure relief channel 60 are locked in a sealed state.
When the pressure relief crown 612 is unscrewed, the pressure relief crown 612 moves toward the outside of the multi-layer watch 100 when the pressure relief crown 612 is unscrewed, and the pressure relief crown 612 and the first seal ring 661 are dislocated to be in clearance fit, so that the sealing between the pressure relief crown 612 and the pressure relief channel 60 is released, and a clearance is formed between the pressure relief crown 612 and the pressure relief pillar 611. If the pressure in the waterproof vapor chamber 30 is too high, the pressure release pillar 611 is pushed to move towards the outside, after the pressure release pillar 611 moves a certain distance, the pressure release pillar 611 is staggered from the position of the second sealing ring 662, and the two are in clearance fit, and the seal between the pressure release pillar 611 and the pressure release channel 60 is opened, so that the pressure release can be performed. When the pressure is reduced to a certain degree, the pressure relief column 611 moves towards the waterproof steam cavity 30 under the action of the pressure relief elastic element 62, and the pressure relief column 611 contacts with the second sealing ring 662, so that the pressure relief column 611 and the pressure relief channel are in a sealed state, and the pressure relief is stopped.
In this embodiment, the pressure relief pillar 611 and the pressure relief crown 612 are two independent components that can be separated, and when the pressure relief crown 612 rotates, the pressure relief pillar 611 is not driven to rotate, so as to avoid affecting the elastic structure; when the pressure releasing pillar 611 moves along the pressure releasing channel 60, the pressure releasing pillar 611 will not drive the pressure releasing cap 612 to move, so as to ensure the flexibility of the movement of the pressure releasing pillar 611, and enable it to release pressure in time.
In the multilayer structure wristwatch according to the first and second embodiments of the present invention, the peripheral surface of the center post 6123 of the pressure relief crown 612 is hermetically connected to the pressure relief channel 60 by the first seal ring 661, and here, other portions of the pressure relief crown 612 may be hermetically connected to the pressure relief channel 60. In the pressure relief protection structure and the corresponding multi-layer wristwatch according to the third embodiment of the present invention, as shown in fig. 12 and 13, the first seal ring 661 is disposed on the side of the second stopper portion 6011 close to the pressure relief crown 612, and the inner diameter of the first seal ring 661 is larger than the outer diameter of the pressure relief outer end 611a of the pressure relief pillar 611, so that the first seal ring 661 and the pressure relief outer end 611a always maintain a clearance fit. As shown in fig. 12, when the pressure relief protecting structure 6 is in a sealed state, the first sealing ring 661 is pressed between the second limiting portion 6011 and the inner end of the central pillar 6123, so that the pressure relief crown 612 and the pressure relief channel 60 are in a sealed state. When pressure relief is required, the pressure relief crown 612 is unscrewed, as shown in fig. 13, so that the central pillar 6123 is separated from the first sealing ring 661, the pressure relief crown 612 and the pressure relief channel 60 are in an open state, and when the pressure in the waterproof vapor chamber 30 is greater than the elastic force of the pressure relief elastic member 62, the pressure relief pillar 611 moves to perform pressure relief.
In the multilayer watch 100 according to the embodiment of the present invention, the central pillar 6123 of the pressure relief crown 612 is connected to the pressure relief channel 60 by the first sealing ring 661, and here, a sealing structure may be disposed at another portion of the pressure relief crown 612 to seal the pressure relief channel 60. For example, a sealing structure is provided between the inner wall of the pressure relief ring 6122 of the pressure relief crown 612 and the outer wall of the pressure relief pipe 61, or a sealing structure is provided between the end face of the pressure relief ring 6122 and the outer wall of the outer middle frame 22.
In the pressure relief protection structure 6 of the foregoing embodiment, steam is exhausted and pressure is relieved through the gap between the pressure relief channel 60 and the pressure relief piece 61, so that relatively smooth pressure relief is realized, and a large amount of liquid is prevented from flowing out. In the watch and the pressure relief protection structure having a multilayer structure according to the fourth embodiment of the present invention, the difference from the previous embodiments is mainly the pressure relief protection structure 6.

The outer periphery of the sealing edge 642 is in clearance fit with the inner wall of the pressure relief channel 60, and pressure relief can be performed through the clearance between the outer periphery of the sealing edge 642 and the inner wall of the pressure relief channel 60. When pressure relief is required, the pressure relief crown 612 is unscrewed, if the pressure in the vapor proof cavity 30 is too high, the pressure relief column 611 is pushed to move towards the pressure relief crown 612, the pressure relief column 611 drives the sealing plug 64 to move, the sealing edge 642 of the sealing plug 64 is separated from the second limiting portion 6011, so that the pressure relief channel 60 is in an open state, and pressure relief is performed by using a gap between the sealing plug 64 and the inner wall of the pressure relief channel 60.
After the pressure relief crown 612 is opened, the sealing plug 64 is pulled out, and the pressure relief straight passage 610 can be used for quickly relieving pressure. Meanwhile, the pressure relief straight passage 610 can also be used for injecting liquid into the waterproof vapor chamber 30.
In order to facilitate the removal of the sealing plug 64, as shown in fig. 16, in the multilayer watch 100 according to the fifth embodiment of the present invention, a pull ring 643 is further disposed on the sealing plug 64, a sealing rim 642 is disposed between the pull ring 643 and the sealing post 641, and a clearance groove 6120 is disposed on the pressure relief crown 612 corresponding to the pull ring 643. When the pressure relief crown 612 is removed, the pull ring 643 can be exposed, and the sealing plug 64 can be conveniently taken out by using the pull ring 643.
In the above embodiment, the inner case 1 and the outer case 2 of the multilayer watch case 100 are members that can be separated independently, and as another embodiment, a part of the members between the inner case 1 and the outer case 2 may be a whole. 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 the gas is prevented from being blocked in the time display region, the inner bottom 13 of the inner case 1 and the outer bottom 23 of the outer case 2 may be integrally formed, and the steam-proof chamber 30 and the inner case 1 may be sealed together during assembly.
