Multi-layered watch for easy timekeeping

Abstract

This invention provides a multi-layered watch for easy time confirmation. From the inside out, it comprises a sealed cavity, a first sealing structure, a waterproof cavity, and a second sealing structure. The sealed cavity is enclosed within the first sealing structure. The waterproof cavity is filled with liquid. The first sealing structure prevents liquid from the waterproof cavity from entering the sealed cavity, while the second sealing structure prevents liquid leakage. In a humid environment, if moisture passes through the second sealing structure, it will merge with the liquid and will not pass through the first sealing structure, thus preventing damage to the internal structure. The multi-layered watch includes a crown assembly and support components. The crown and barre of the crown assembly are located at the 3 o'clock position. The three support components are located at the 6 o'clock, 12 o'clock, and 9 o'clock positions, respectively. The three support components and the barre are visible through the multi-layered watch, serving as a dial indicator for easy time confirmation.

Description

[0001] This application is a divisional application of the invention entitled "Multi-layer structure watch with waterproof function", filed on June 15, 2022, with application number 2022106804754. Technical Field

[0002] This invention relates to the field of watches, and in particular to a multi-layered watch that facilitates timekeeping. Background Technology

[0003] Current watch designs typically feature waterproof seals to prevent liquids from entering the watch. However, when a user wears the watch in a humid environment, such as a sauna or while cooking, the high ambient temperature can cause the seals to fail. Furthermore, moisture can more easily penetrate the seals and enter the watch, damaging it and affecting its usability. Summary of the Invention

[0004] This invention provides a multi-layered watch that facilitates time confirmation, effectively preventing damage from moisture in the environment and making time confirmation easy.

[0005] The technical solution of this invention is as follows:

[0006] This invention provides a multi-layered watch for easy time confirmation, characterized in that the multi-layered watch is provided with, from the inside out, a sealed cavity, a first sealing structure, a waterproof vapor chamber, and a second sealing structure; the sealed cavity is sealed within the first sealing structure; the waterproof vapor chamber is used to fill liquid, and the waterproof vapor chamber is sealed between the first sealing structure and the second sealing structure;

[0007] The multi-layered watch is equipped with a crown assembly for adjusting the time. The crown assembly includes a crown and a barre. The crown is located on the outside of the multi-layered watch and is connected to the sealed cavity via the barre. The crown and the barre are located at the 3 o'clock position of the multi-layered watch. The multi-layered watch is equipped with three support members, which are rod-shaped. The three support members are respectively located at the 6 o'clock, 12 o'clock, and 9 o'clock positions of the multi-layered watch. The three support members and the barre all extend radially along the multi-layered watch and can be seen through the multi-layered watch.

[0008] The multi-layered watch includes an inner case and an outer case; a sealing cavity is formed inside the inner case, and the inner case is disposed inside the outer case; a first sealing structure is disposed on the inner case and seals the sealing cavity inside the inner case; a second sealing structure is disposed on the outer case and seals the inner case inside the outer case; a waterproof cavity is located between the inner case and the outer case; and a support member is connected between the inner case and the outer case.

[0009] The inner shell includes an endoscope, and the outer shell includes an outer mirror. Both the endoscope and the outer mirror are made of light-transmitting material. The outer diameter of the outer mirror is larger than the outer diameter of the inner shell. The three support members and the bar axis can all be visualized on the outer shell through the outer mirror.

[0010] The first sealing structure includes a first top sealing ring and a first bottom sealing ring. The inner shell also includes an inner middle frame and an inner bottom cover. The endoscope is sealed to the inner middle frame through the first top sealing ring, and the inner bottom cover is sealed to the inner middle frame through the first bottom sealing ring. The endoscope, the first top sealing ring, the inner middle frame, the first bottom sealing ring, and the inner bottom cover together form the sealing cavity. The two ends of the support member are respectively connected to the inner middle frame and the outer shell.

[0011] The second sealing structure includes a second top sealing ring and a second bottom sealing ring. The outer shell also includes an outer middle frame and an outer bottom cover. The outer mirror is sealed to the outer middle frame through the second top sealing ring, and the outer bottom cover is sealed to the outer middle frame through the second bottom sealing ring. The inner shell is sealed within the enclosed space formed by the outer mirror, the second top sealing ring, the outer middle frame, the second bottom sealing ring, and the outer bottom cover. The support member is connected to the outer middle frame.

[0012] In this configuration, one end of the support member is integrally formed with the inner frame, and the other end is detachably and fixedly connected to the outer shell; or...

[0013] One end of the support member is integrally formed with the outer shell, and the other end is detachably and fixedly connected to the inner frame.

[0014] The endoscope and the exoscope are integrally formed.

[0015] The first sealing structure includes a first top sealing ring, and the inner shell also includes an inner middle frame and an inner bottom cover. The endoscope and the inner middle frame are sealed together by the first top sealing ring, and the inner bottom cover and the inner middle frame are integrally formed; or...

[0016] The first sealing structure includes a first bottom sealing ring, and the inner shell also includes an inner middle frame and an inner bottom cover. The endoscope and the inner middle frame are integrally formed from transparent material, and the inner bottom cover and the inner middle frame are sealed and connected by the first bottom sealing ring.

[0017] The second sealing structure includes a second top sealing ring, and the outer casing also includes an outer middle frame and an outer bottom cover. The outer mirror and the outer middle frame are sealed together by the second top sealing ring. The outer bottom cover and the outer middle frame are integrally formed, or...

[0018] The second sealing structure includes a second bottom sealing ring. The outer shell also includes an outer middle frame and an outer bottom cover. The outer mirror and the outer middle frame are integrally formed from transparent material. The outer bottom cover and the outer middle frame are sealed together by the second bottom sealing ring.

[0019] The waterproof vapor chamber has a gas-retaining groove on its side wall for containing gas. The gas-retaining groove is located at the top of the waterproof vapor chamber and is annular along the circumference of the multi-layer structure watch.

[0020] Compared to existing technologies, the advantages of this invention are as follows: The first sealing structure seals the sealing cavity to prevent liquid from the waterproof cavity from entering it; the second sealing structure isolates the waterproof cavity from the outside of the multi-layer watch, preventing liquid leakage. When the multi-layer watch with waterproof function is in a humid environment, if moisture passes through the second sealing structure, it will enter the waterproof cavity, come into contact with the liquid, cool, and merge into the liquid, thus preventing it from passing through the first sealing structure. This avoids moisture entering the sealing cavity and damaging the internal structure, ensuring the normal operation of the multi-layer watch. The three support members and the bar axis serve as dial indicators, allowing users to easily check the time. Attached Figure Description

[0049] Please see Figure 1 , Figure 2 and Figure 3A preferred embodiment of the present invention provides a multi-layered watch 100 with waterproof function. The multi-layered watch 100 with waterproof function has, from the inside out, a sealing cavity 90, a first sealing structure 10, a waterproof cavity 30, and a second sealing structure 20. The sealing cavity 90 is used to accommodate the watch movement 900 and is sealed within the first sealing structure 10. The waterproof cavity 30 is filled with liquid (not shown) and is sealed between the first sealing structure 10 and the second sealing structure 20, thereby sealing the liquid between the two structures. Preferably, the liquid is water, but other liquids capable of mixing water vapor can also be used.

[0050] The first sealing structure 10 seals the sealing cavity 90 to prevent liquid from the waterproof cavity 30 from entering the sealing cavity 90. The second sealing structure 20 isolates the waterproof cavity 30 from the outside of the multi-layered watch 100 with waterproof function, preventing liquid leakage from the waterproof cavity 30. When the multi-layered watch 100 with waterproof function is in a humid environment, if moisture passes through the second sealing structure 20, the moisture will enter the waterproof cavity 30, come into contact with the liquid, cool, and merge into the liquid. Therefore, it will not pass through the first sealing structure 10 again, preventing moisture from entering the sealing cavity 90 and damaging the internal structure, thus ensuring the normal operation of the multi-layered watch 100 with waterproof function.

[0051] In this embodiment, the multi-layered watch 100 with waterproof function includes an inner case 1 and an outer case 2; the inner case 1 is disposed inside the outer case 2; a first sealing structure 10 is disposed on the inner case 1 and seals the sealing cavity 90 within the inner case 1; a second sealing structure 20 is disposed on the outer case 2 and seals the inner case 1 within the outer case 2; and the waterproof cavity 30 is located between the inner case 1 and the outer case 2. By disposing of the first sealing structure 10 and the second sealing structure 20 on the inner case 1 and the outer case 2 respectively, the first sealing structure 10 and the second sealing structure 20 can be relatively independent and can be assembled and disassembled separately, thus preventing the liquid in the waterproof cavity 30 from contacting the watch movement 900 during assembly and disassembly. During disassembly, the outer case 2 is opened first to expose the waterproof cavity 30, and the liquid inside is drained completely before the inner case 1 is opened to maintain the watch movement 900, thereby completely preventing the watch movement 900 from contacting the liquid.

[0052] More specifically, in this embodiment, as Figure 3 As shown, the inner shell 1 is suspended in the outer shell 2, which allows the waterproof vapor chamber 30 and its liquid to be more fully covered outside the inner shell 1, thus achieving a better waterproof vapor effect.

[0053] See Figure 3 and Figure 4A support member 3 connects the outer wall of the inner shell 1 to the inner wall of the outer shell 2. The support member 3 allows the inner shell 1 to be roughly positioned within the outer shell 2. In other embodiments, the support member 3 may not be provided between the inner shell 1 and the outer shell 2, allowing them to move relative to each other. The liquid in the waterproof cavity 30 can provide a cushioning and shock absorption effect for the inner shell 1 and the watch movement 900.

[0054] In this embodiment, the support member 3 is fixedly connected between the inner shell 1 and the outer shell 2 to fix the relative positions of the inner shell 1 and the outer shell 2, preventing them from moving relative to each other, so that the user can easily observe the time shown by the watch movement 900. Here, in other embodiments, the support member 3 may not be provided between the inner shell 1 and the outer shell 2, and they may move relative to each other. The liquid in the waterproof cavity 30 can provide a buffering and shock-absorbing effect on the inner shell 1 and the watch movement 900.

[0055] Furthermore, there are two or more support members 3 arranged circumferentially around the inner shell 1. Using two or more support members 3 to support and position the inner shell 1 can achieve a better fixing effect. At the same time, the axial arrangement of the support members 3 around the inner shell 1 can prevent the support members 3 from obstructing the time display on the front of the inner shell 1. In this embodiment, there are three support members 3, which are respectively set at the 6 o'clock, 12 o'clock, and 9 o'clock positions of the multi-layer structure watch 100 with waterproof function. Here, in other embodiments, there may also be two, four, or other numbers of support members 3.

[0056] The first sealing structure 10 includes a first top sealing ring 101 and a first bottom sealing ring 102. The inner case 1 includes an inner mirror 11, an inner frame 12, and an inner bottom cover 13. The inner mirror 11 and the inner frame 12 are sealed together by the first top sealing ring 101, and the inner bottom cover 13 and the inner frame 12 are sealed together by the first bottom sealing ring 102. The watch movement 900 is sealed within the enclosed space formed by the inner mirror 11, the first top sealing ring 101, the inner frame 12, the first bottom sealing ring 102, and the inner bottom cover 13. The inner case 1 includes three components: the inner mirror 11, the inner frame 12, and the inner bottom cover 13. Together with the first top sealing ring 101 and the first bottom sealing ring 102, they form a sealed space to accommodate the watch movement 900, preventing liquid from contacting the watch movement 900. The inner mirror 11 can be made of a light-transmitting material so that the user can see the time displayed on the watch movement 900. In other embodiments, the endoscope 11 and the inner frame 12 can be integrally formed from a transparent material, or the inner frame 12 and the inner bottom cover 13 can be integrally formed, and the first sealing structure 10 can include only the first bottom sealing ring 102 or the first top sealing ring 101.

[0057] The support member 3 is rod-shaped, with its two ends connected to the inner frame 12 and the outer shell 2, respectively. The rod-shaped support member 3 has a relatively small volume, occupies little space in the waterproof cavity 30, and facilitates the connection between the inner frame 12 and the outer shell 2. More specifically, one end is integrally formed with the inner frame 12, and the other end is detachably fixedly connected to the outer shell 2. The integral formation of one end of the support rod with the inner frame 12 creates a seamless connection between the support member 3 and the inner frame 12, reducing the likelihood of liquid entering the inner shell 1. The other end of the support member 3 can be detached from the outer shell 2 to separate the inner shell 1 from the outer shell 2. In other embodiments, the support member 3 may also have one end integrally formed with the outer shell 2 and the other end detachably fixedly connected to the inner frame 12; the shape of the support member 3 may also be block-shaped, sheet-shaped, or other shapes.

[0058] In this embodiment, the multi-layered watch 100 also includes a crown assembly 4 for adjusting the time. The crown assembly 4 includes a crown 41 and a barringbone 42. The crown 41 is located on the outside of the multi-layered watch 100 and is connected to the watch movement 900 via the barringbone 42. The crown 41 and the barringbone 42 are located at the 3 o'clock position of the multi-layered watch 100. The three rod-shaped support members 3 and the barringbone 42 extend radially along the multi-layered watch 100, which has a waterproof function, and are visible through the case 2. The user can see the three support members 3 and the barringbone 42 through the case 2, so that the three support members 3 and the barringbone 42 can function as dial indicators, making it convenient for the user to confirm the time. The barringbone 42 of the crown assembly 4 is sealed to the inner case 1 through a first crown sealing ring 43 to prevent liquid from entering the watch movement 900 through the gap between the barringbone 42 and the inner case 1; the crown 41 of the crown assembly 4 is sealed to the case 2 through a second crown sealing ring 44 to prevent liquid leakage. The first crown seal 43 can form part of the first sealing structure 10, and the second crown seal 44 can form part of the second sealing structure 20.

[0059] The second sealing structure 20 includes a second top sealing ring 201 and a second bottom sealing ring 202. The outer shell 2 includes an outer mirror 21, an outer middle frame 22 and an outer bottom cover 23. The outer mirror 21 and the outer middle frame 22 are sealed together by the second top sealing ring 201, and the outer bottom cover 23 and the outer middle frame 22 are sealed together by the second bottom sealing ring 202. The inner shell 1 is sealed within the enclosed space formed by the outer mirror 21, the second top sealing ring 201, the outer middle frame 22, the second bottom sealing ring 202 and the outer bottom cover 23.

[0060] The outer casing 2, consisting of an outer mirror 21, an outer frame 22, and an outer bottom cover 23, together with a second top sealing ring 201 and a second bottom sealing ring 202, forms a sealed space to accommodate the watch movement 900, preventing liquid from contacting the watch movement 900. The outer mirror 21 can be made of a light-transmitting material so that the user can see the time displayed on the watch movement 900. In other embodiments, the outer mirror 21 and the outer frame 22 can be integrally formed from a transparent material, or the outer frame 22 and the outer bottom cover 23 can be integrally formed, and the second sealing structure 20 may only include the second bottom sealing ring 202 or the second top sealing ring 201.

[0061] The outer diameter of the outer mirror 21 is larger than the outer diameter of the inner shell 1, so that the three support members 3 and the bar axis 42 can be visualized in the outer shell 2 through the outer mirror 21.

[0062] A groove 220 is provided on the side of the outer frame 22 facing the outer bottom cover 23. The other end of the support member 3 is pressed into the groove 220 by the second bottom sealing ring 202 and the outer bottom cover 23. During assembly, the other end of the support member 3 is inserted into the groove 220, and then the second bottom sealing ring 202 is placed inside the outer frame 22. The outer bottom cover 23 is then assembled with the outer frame 22. The outer bottom cover 23 applies force to the second bottom sealing ring 202, pressing the other end of the support rod into the groove 220. At the same time, the second bottom sealing ring 202 achieves a sealed connection between the outer frame 22 and the outer bottom cover 23, thereby facilitating the assembly of the support member 3 and the sealing of the outer shell 2.

[0063] In this embodiment, the support member is fixedly connected between the inner shell and the outer shell to fix their relative positions. In other embodiments, the support member can also be rotatably connected between the inner shell and the outer shell, allowing them to rotate relative to each other. For example, the support member is cylindrical, and two supports are used, one at the 3 o'clock position and the other at the 9 o'clock position. The support member is rotatably connected to either the inner shell or the outer shell, allowing them to rotate laterally relative to each other, keeping the inner shell horizontal and thus facilitating the user's viewing of the time.

[0064] Combination Figure 3 and Figure 4 As shown, the side of the outer frame 22 facing the outer bottom cover 23 is stepped, and a slot 220 and a second bottom sealing ring 202 are provided on the stepped surface to facilitate the positioning and assembly of the outer bottom cover 23 and the outer frame 22.

[0065] Furthermore, the outer frame 22 has a two-step structure on the side facing the bottom cover, with a first-step surface 221 and a second-step surface 222. The first-step surface 221 is closer to the inner shell 1 than the second-step surface 222. The outer bottom cover 23 has a two-step structure around its perimeter that mates with the outer frame 22. There are two second bottom sealing rings 202, which are respectively set on the first-step surface 221 and the second-step surface 222. The slot 220 is set on the first-step surface 221. By utilizing the two-step structure between the outer bottom cover 23 and the outer frame 22 and the two second bottom sealing rings 202, the sealing performance can be effectively guaranteed, and water leakage from the slot 220 can be prevented.

[0066] An annular groove 2220 is provided on the second-level step surface 222, and a second bottom sealing ring 202 is provided in the annular groove 2220 to facilitate the positioning between the second bottom sealing ring 202 and the outer middle frame 22, and to facilitate assembly and connection.

[0067] Combination Figure 5 , Figure 6 , Figure 7 ,and Figure 8 As shown, the multi-layered watch 100 with waterproof function also includes an injection device 5. The injection device 5 includes an injection channel 50, an injection cover 51, and an injection plug 52. The injection channel 50 connects the inner and outer sides of the multi-layered watch 100. More specifically, the injection channel connects the outer side of the multi-layered watch 100 with the waterproof cavity 30. The injection plug 52 is inserted into the injection channel 50, and a seal is provided between the two. The injection cover 51 is placed over the entrance of the injection channel 50 to limit the injection plug 52 to the injection channel 50, making it difficult for the injection plug 52 to fall out, thereby improving the sealing performance.

[0068] By opening the injection cap 51 and pulling out the injection plug 52 through the injection device 5, the injection channel 50 is exposed, allowing liquid to be injected into the waterproof vapor chamber 30. The injection channel 50 forms a channel for injecting liquid. The injection cap 51 and the injection plug 52 form a double protective structure to seal the injection channel 50, ensuring its sealing performance and preventing liquid leakage. When liquid injection is required, first open the injection cap 51 to expose the injection plug 52, then pull out the injection plug 52 to fully open the injection channel 50. A syringe can then be inserted into the injection channel 50 to inject liquid into the waterproof vapor chamber 30.

[0069] In this embodiment, the injection device 5 is disposed on the outer frame 22 of the multi-layer structure watch 100, which avoids the impact of disassembly and maintenance on the injection device 5. Of course, in other embodiments, the injection device 5 may also be disposed on the outer bottom cover 23 or other parts of the outer casing 2.

[0070] An injection through-hole 105 is provided on the outer casing 2, which connects the outer side of the outer casing 2 and the waterproof vapor chamber 30. More specifically, the injection through-hole 105 is provided on the outer middle frame 22 to connect the inner and outer sides of the outer middle frame 22.

[0071] The injection device also includes an injection tube 53, the outer wall of which is interference-fitted with the injection through-hole 105, and a sealing structure can be provided to ensure the sealing performance of both. The space inside the injection tube 53 forms the injection channel 50. By using the injection tube 53 to form the injection channel 50, the machining accuracy requirements of the injection through-hole 105 can be reduced, and the diameter of the injection through-hole 105 can be set relatively large to facilitate machining. Here, in other embodiments, the injection channel 50 can also be formed directly through the injection through-hole 105 without providing an injection tube 53.

[0072] like Figure 7 As shown, the injection tube 53 includes a first injection tube 531 and a second injection tube 532 coaxially arranged. The second injection tube 532 is closer to the waterproof vapor chamber 30 than the first injection tube 531. The outer diameter of the first injection tube 531 is larger than the outer diameter of the second injection tube 532, and the outer walls of the first injection tube 531 and the second injection tube 532 are transitioned by a bevel. The first injection tube 531 is interference-fitted with the injection through hole 105, and the second injection tube 532 is clearance-fitted with the injection through hole 105. First, the second injection tube 532 is inserted into the injection through hole 105, and then the first injection tube 531 is inserted into the injection through hole 105 through the bevel, which facilitates the assembly of the injection tube 53 into the injection through hole 105. The inner diameters of the first injection tube 531 and the second injection tube 532 are the same to facilitate the insertion and removal of the injection plug 52.

[0073] The injection tube 53 also includes an injection retaining ring 533, which is coaxially arranged with the first injection tube 531 and the second injection tube 532. The first injection tube 531 is connected between the injection retaining ring 533 and the second injection tube 532. The outer diameter of the injection retaining ring 533 is larger than the outer diameter of the first injection tube 531, and an injection outer step is formed between the outer peripheral surfaces of the injection retaining ring 533 and the first injection tube 531. When assembling the injection tube 53, the injection outer step formed by the injection retaining ring 533 can block the outer edge of the injection through hole 105, which can limit the insertion depth of the injection tube 53 in the multi-layer structure watch 100 and ensure that the injection device 5 is assembled in place.

[0074] like Figure 7 and Figure 8As shown, the injection plug 52 is cylindrical, with a sealing end 52a and an external end 52b. The sealing end 52a is inserted into the injection channel 50. The injection device 5 also includes an injection sealing ring 54, which is disposed between the injection plug 52 and the injection channel 50 to achieve a sealed connection with the injection channel 50. The external end 52b is located outside the injection channel 50 and inside the injection cover 51, allowing the injection plug 52 to be easily removed using the external end 52b.

[0075] The injection device 5 also includes an injection sealing ring 54. An injection ring groove 524 is provided on the injection plug 52 along its circumference, and the injection sealing ring 54 is limited in the injection ring groove 524 to realize the positioning of the injection sealing ring 54 on the injection plug 52. When the injection plug 52 is pulled out, the injection sealing ring 54 can be pulled out at the same time.

[0076] Two injection sealing rings 54 are arranged axially along the injection plug 52. Using two sealing rings achieves a better sealing effect. Two injection annular grooves 524 are provided, and the two injection sealing rings 54 are respectively positioned within these grooves to ensure their placement on the injection plug 52. When the injection plug 52 is removed, the two injection sealing rings 54 can be removed along with it. In this embodiment, the injection sealing rings 54 are used to achieve a seal between the injection plug 52 and the injection channel 50. However, in other embodiments, the injection plug may be made entirely of silicone or rubber, with an interference fit to the injection channel to achieve a seal.

[0077] An annular flange 521 is provided on the circumferential surface of the injection plug 52. The outer diameter of the annular flange 521 is smaller than the inner diameter of the injection retaining ring 533, and the inner diameter of the injection retaining ring 533 is larger than the inner diameter of the first injection tube 531. An injection inner step is formed between the injection retaining ring 533 and the first injection tube 531 in the injection channel 50. When the injection plug 52 is inserted into the injection tube 53, the annular flange 521 is located inside the injection retaining ring 533 and abuts against the first injection tube 531. That is, the annular flange 521 abuts against the injection inner step, which can limit the depth of the injection plug 52 inserted into the injection channel 50, while ensuring that the injection plug 52 and the injection tube 53 are properly assembled, so that the external end 52b can be better exposed outside the injection tube 53, making it convenient to pull out again.

[0078] The peripheral end 52b of the injection plug 52 is provided with an outer flange 522, which facilitates the application of force to the injection plug 52. Furthermore, the outer flange 522 is annular, surrounding the injection plug, and its circumferential surface is serrated. This serrated outer flange 522 allows the injection plug 52 to be removed while rotating it, facilitating its removal. In other embodiments, the outer flange may also consist of multiple protrusions evenly distributed on the peripheral end.

[0079] An injection cap 51 is placed over the entrance of the injection channel 50 to enclose the injection plug 52 within the multi-layered watch case 100 and the injection cap 51. A seal may also be provided between the injection cap 51 and the entrance of the injection channel 50 to seal the injection plug 52 between the multi-layered watch case 100 and the injection cap 51, further improving the sealing performance.

[0080] In this embodiment, the injection cap 51 is threaded to the outer peripheral surface of the injection retaining ring 533 of the injection tube 53, so that the injection cap 51 covers the entrance of the injection channel 50. In other embodiments, the injection cap 51 can also be directly connected to the outer shell 2, which can be a threaded connection, a snap-fit ​​connection, or a connection through other fasteners.

[0081] The injection device 5 also includes a chain 55. A chain 55 connects the injection cap 51 to the outer frame 22 of the housing 2. Using the chain 55, the injection cap 51 can be hung on the housing 2 after being opened, preventing loss. One end of the chain 55 is rotatably engaged with the circumferential surface of the injection cap 51 to avoid affecting the rotation and disassembly of the injection cap 51. The other end of the chain 55 is connected to the housing 2.

[0082] More specifically, the injection cap 51 includes an outer cap 511 and an inner ring 512. The outer cap 511 and the inner ring 512 are threaded together, and an annular rotating groove 515 is formed between them. One end of the chain 55 is provided with a rotating ring 551, which is rotatably disposed in the rotating groove 515, thereby realizing the rotational engagement between the chain 55 and the injection cap 51.

[0083] like Figure 3 , Figure 9 , Figure 10 and Figure 11 As shown, the multi-layered watch 100 also includes a pressure relief device 6, which includes a pressure relief channel 60, a pressure relief component 61, and a pressure relief elastic component 62. The pressure relief channel 60 connects the inner and outer sides of the multi-layered watch 100. More specifically, the pressure relief channel 60 connects the outer side of the multi-layered watch 100 with the waterproof vapor chamber 30 inside. The pressure relief component 61 is slidably engaged with the pressure relief channel 60, and the relative sliding direction between the two is the axial direction of the pressure relief channel 60, so that the pressure relief component 61 can move between a sealed position and a pressure relief position. The sealed position is closer to the waterproof vapor chamber 30 inside the multi-layered watch 100 than the pressure relief position, which allows the pressure relief component 61 to move closer to or further away from the waterproof vapor chamber 30 inside the multi-layered watch 100. The pressure relief elastic component 62 is connected between the pressure relief component 61 and the pressure relief channel 60, and is used to provide a force to the pressure relief component 61 to move toward the waterproof vapor chamber 30.

[0084] When the pressure relief component 61 is in the sealed position, the pressure relief component 61 is sealed to the pressure relief channel 60, and the pressure relief device 6 is in a sealed state.

[0085] When the pressure inside the waterproof cavity 30 becomes excessive, the pressure relief component 61, under the influence of the internal pressure of the waterproof cavity 30, overcomes the force of the pressure relief elastic component and moves towards the pressure relief position. When the pressure relief component 61 moves to the pressure relief position, it engages with the pressure relief channel 60, and the waterproof cavity 30 is connected to the outside of the multi-layer watch 100 to release the pressure inside the waterproof cavity 30. The pressure relief elastic component 62 is in an elastic deformation state and provides a force to the pressure relief component 61 to move towards the sealing position. The sealing position is closer to the inside of the multi-layer watch 100, i.e., closer to the waterproof cavity 30, relative to the pressure relief position. When the pressure inside the waterproof cavity 30 is released to a certain extent, the pressure relief component 61 moves towards the sealing position under the action of the pressure relief elastic component 62, so that the pressure relief component 61 and the pressure relief channel 60 are sealed to limit further pressure release.

[0086] In this embodiment, as Figure 10 and Figure 11 As shown, the multi-layered watch 100 is provided with a pressure relief hole 106, which connects the outer side of the multi-layered watch 100 and the waterproof cavity 30. More specifically, the pressure relief hole 106 is provided on the outer frame 22 to connect the inner and outer sides of the outer frame 22.

[0087] The pressure relief device 6 also includes a pressure relief pipe 63, which is disposed within the pressure relief through hole 106. The outer wall of the pressure relief pipe 63 can be press-fitted with the pressure relief through hole 106, and a sealing structure can be provided to ensure the sealing performance of both. The space within the pressure relief pipe 63 forms the pressure relief channel 60. Using the pressure relief pipe 63 to form the pressure relief channel 60 can reduce the machining accuracy requirements of the pressure relief through hole 106, and the diameter of the pressure relief through hole 106 can be set to be relatively large to facilitate machining. Here, in other embodiments, the pressure relief channel 60 can also be formed directly through the pressure relief through hole 106 without providing a pressure relief pipe 63.

[0088] like Figure 10 As shown, the pressure relief pipe 63 includes a first pressure relief pipe 631 and a second pressure relief pipe 632 coaxially arranged. The second pressure relief pipe 632 is closer to the waterproof vapor chamber 30 than 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 transitioned by a bevel. The first pressure relief pipe 631 is press-fitted with the pressure relief through hole 106, and the second pressure relief pipe 632 is clearance-fitted with the pressure relief through hole 106. First, the second pressure relief pipe 632 is inserted into the pressure relief through hole 106, and then the first pressure relief pipe 631 is inserted into the pressure relief through hole 106 through the bevel, thereby facilitating the assembly of the pressure relief pipe 63 into the pressure relief through hole 106.

[0089] The pressure relief pipe 63 also includes a pressure relief retaining ring 633, which is coaxially arranged with the first pressure relief pipe 631 and the second pressure relief pipe 632. The first pressure relief pipe 631 is connected between the pressure relief retaining ring 633 and the second pressure relief pipe 632. The outer diameter of the pressure relief retaining ring 633 is larger than the outer diameter of the first pressure relief pipe 631, and a pressure relief outer step is formed between the outer peripheral surfaces of the pressure relief retaining ring 633 and the first pressure relief pipe 631. When assembling the pressure relief pipe 63, the pressure relief outer step formed by the pressure relief retaining ring 633 can block the outer edge of the pressure relief through hole 106, which can limit the depth of the pressure relief pipe 63 inserted into the case 2 of the multi-layer structure watch, while ensuring that the pressure relief pipe 63 is properly assembled.

[0090] In this embodiment, the pressure relief component 61 includes a pressure relief column 611 and a pressure relief crown 612. The pressure relief column 611 is slidably disposed in the pressure relief channel 60 along the axial direction of the pressure relief channel 60. The pressure relief column 611 has an inner pressure relief end 611b and an outer pressure relief end 611a. The inner pressure relief end 611b is close to the waterproof cavity 30 inside the multi-layer structure watch 100 relative to the outer pressure relief end 611a. The inner pressure relief end 611b is connected to the pressure relief elastic component 62. The pressure relief crown 612 is located at the outer pressure relief end 611a. The pressure relief crown 612 is threadedly connected to the opening of the pressure relief channel 60 to restrict the movement of the pressure relief column 611. The pressure relief column 611 and / or the pressure relief crown 612 can be sealed with the pressure relief channel 60. In this embodiment, the pressure relief crown 612 is sealed with the pressure relief channel 60 to seal the pressure relief column 611 inside the pressure relief channel 60.

[0091] like Figure 11 As shown, a first limiting part 6111 is provided on the edge of the inner end 611b of the pressure relief device, and a second limiting part 6011 is provided on the inner wall of the pressure relief channel 60. The pressure relief elastic element 62 is a compression spring, sleeved on the pressure relief column 611 and located between the first limiting part 6111 and the second limiting part 6011. When the pressure relief column 611 moves outward toward the waterproof vapor chamber 30, the first limiting part 6111 and the second limiting part 6011 move closer to each other, causing the elastic element to compress. The elastic element can then provide a force to the pressure relief column 611 to move toward the waterproof vapor chamber 30. By utilizing the cooperation of the first limiting part 6111, the second limiting part 6011, and the pressure relief elastic element 62, the pressure relief device 6 can automatically return to a sealed state after appropriate pressure relief, while preventing the pressure relief column 611 from falling out of the pressure relief channel 60.

[0092] In this embodiment, the pressure relief column 611 and the pressure relief crown 612 are fixedly connected, and both can move or be positioned simultaneously. When the pressure relief crown 612 is threadedly connected to the inlet of the pressure relief channel 60, the pressure relief crown 612 can restrict the movement of the pressure relief column 611 within the pressure relief channel 60 and keep the pressure relief component 61 and the pressure relief channel 60 in a sealed state. Due to the thread between the pressure relief crown 612 and the inlet of the pressure relief channel 60, the pressure relief component 61 can only move within the pressure relief channel 60 by rotating the pressure relief crown 612 under the action of external force.

[0093] like Figure 12 As shown, when the pressure relief crown 612 is separated from the thread at the entrance of the pressure relief channel 60, that is, when the pressure relief crown 612 is in the unscrewed state, the pressure relief component 61 as a whole can move within the pressure relief channel 60 to open or seal the pressure relief channel 60.

[0094] The pressure relief crown 612 restricts the movement of the pressure relief column 611. When pressure needs to be released, the user can rotate the pressure relief crown 612 to release pressure, thus avoiding automatic pressure release when it is not necessary.

[0095] More specifically, the pressure relief crown 612 includes a pressure relief plate 6121, a pressure relief ring 6122, and a central post 6123. The pressure relief ring 6122 is fixedly disposed along the periphery of the pressure relief plate 6121. The central post 6123 is coaxially disposed with the pressure relief ring 6122 and is located inside the pressure relief ring 6122. One end of the central post 6123 is fixedly connected to the pressure relief plate 6121. The other end of the central post 6123 is disposed opposite to the pressure relief outer end 611a.

[0096] The pressure relief ring 6122 is threadedly connected to the inlet of the pressure relief channel 60. More specifically, the inner surface of the pressure relief ring 6122 is threadedly connected to the outer circumferential surface of the pressure relief retaining ring 633 of the pressure relief pipe 63, so as to facilitate the placement of the pressure relief column 611 within the pressure relief channel 60. The pressure relief retaining ring 633 is located between the pressure relief pipe 63 and the pressure relief ring 6122.

[0097] In this embodiment, the central column 6123 is sealed to the pressure relief channel 60. Through the sealing structure between the central column 6123 and the pressure relief channel 60, the pressure relief component 61 and the pressure relief channel 60 can be sealed, thereby sealing the pressure relief column 611 within the pressure relief channel 60.

[0098] The inner wall of the pressure relief channel 60 is provided with a pressure relief ring groove 601, and a pressure relief sealing ring 602 is provided 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. When the pressure relief component 61 moves, it will not cause the pressure relief sealing ring 602 to move. When the pressure relief component 61 moves, the pressure relief sealing ring 602 connects to the outer wall of the central column 6123, realizing a sealed connection between the pressure relief crown 612 and the pressure relief channel 60. At this time, the pressure relief component 61 is in the sealed position.

[0099] like Figure 11 As shown, when the pressure relief component 61 is in the sealed position, the pressure relief crown 612 is in contact with and sealed to the pressure relief sealing ring 602; as Figure 12 As shown, when the pressure relief component 61 moves to the pressure relief position, the central post 6123 of the pressure relief crown 612 separates from the pressure relief sealing ring 602. In other embodiments, the pressure relief sealing ring can also be disposed on the outer circumferential surface of the pressure relief retaining ring, such that the pressure relief sealing ring is located between the pressure relief retaining ring and the pressure relief ring, thereby achieving contact and separation between the pressure relief crown and the pressure relief sealing ring.

[0100] In this embodiment, the sealing between the pressure relief component 61 and the pressure relief channel 60 is achieved through a sealing fit between the pressure relief crown 612 and the pressure relief channel 60. This seals the pressure relief elastic component 62 and other structures within the outer casing 2, preventing liquid from remaining at the pressure relief elastic component 62 and causing corrosion due to contact with outside air. In other embodiments, the sealing structure between the pressure relief component 61 and the pressure relief channel 60 can also be located between the pressure relief column 611 and the pressure relief channel 60; alternatively, both the pressure relief column 611 and the pressure relief crown 612 can be sealed to the pressure relief channel 60.

[0101] The central column 6123 is tubular, and its inner surface is threaded to the pressure-relieving outer end 611a of the pressure-relieving column 611, and is always kept in a tightened state to facilitate the fixed assembly of the central column 6123 and the pressure-relieving pipe 63. A slot is provided on the end face of the pressure-relieving inner end 611b of the pressure-relieving column 611 to allow the central column 6123 to be tightened to the pressure-relieving column 611 using a flathead screwdriver. In other embodiments, the central column 6123 and the pressure-relieving column 611 can also be fixedly connected by an interference fit. The cooperation between the central column 6123 and the pressure relief column 611 allows the pressure relief column 611 and the pressure relief crown 612 to be connected as a single unit, enabling them to move as a whole. During pressure relief operations, neither the pressure relief crown 612 nor the pressure relief column 611 will be removed from the multi-layered watch 100, thus preventing the pressure relief crown 612 from falling off and being lost during pressure relief. When the pressure relief device 6 is in a sealed state, only one of the pressure relief column 611 and the pressure relief crown 612 needs to be sealed to the pressure relief channel 60, rather than both of them needing to be sealed to the pressure relief channel 60, which simplifies the structure and reduces costs. Of course, based on this embodiment, both the pressure relief column 611 and the pressure relief crown 612 can also be sealed.

[0102] When the pressure relief device 6 is in a sealed state, the central column 6123 of the pressure relief pipe 63 is connected and sealed with the pressure relief sealing ring 602. When pressure relief is required, the pressure relief crown 612 is loosened. As the pressure relief crown 612 moves the pressure relief column 611 away from the waterproof vapor chamber 30, the central column 6123 of the pressure relief crown 612 moves axially away from the position in contact with the pressure relief sealing ring 602, causing the central column 6123 and the pressure relief sealing ring 602 to misalign, thereby releasing the seal and putting the pressure relief device 6 in an open state. The waterproof vapor chamber 30 is connected to the outside through the gap between the pressure relief channel 60, the pressure relief column 611, and the pressure relief crown 612, allowing for pressure relief.

[0103] In the first embodiment described above, the injection cap 51 is removed first, followed by the injection plug 52, before liquid can be injected. After removing the injection plug 52, it needs to be placed aside, as there is a risk of it falling and being lost. The second embodiment of the present invention further improves the structure of the injection cap 51 to avoid this problem.

[0104] like Figure 13 As shown, in the multi-layer structure watch 100 with waterproof function provided in the second embodiment of the present invention, an annular retaining ring 5121 is provided on the inner wall of the inner ring 512 of the injection cover 51. The inner diameter of the annular retaining ring 5121 is smaller than the outer diameter of the outer flange 522 of the injection plug 52, so that the outer flange 522 can be limited between the annular retaining ring 5121 and the outer cover 511 of the injection cover 51, so that the injection plug 52 will not be completely separated from the injection cover 51, thereby avoiding the loss of the injection plug 52.

[0105] The outer flange 522 is movably disposed within the injection cap 51 along the axial direction of the injection plug 52. When the injection device 5 is in a sealed state, the outer flange 522 abuts against the outer cap 511, and a gap is formed between the outer flange 522 and the annular retaining ring 5121. When the injection cap 51 is unscrewed to separate the injection cap 51 from the outer shell 2, the outer flange 522 can abut against the annular retaining ring 5121, and by pulling the injection cap 51 outward, the injection plug 52 can be removed from the injection channel 50.

[0106] Furthermore, the annular retaining ring 5121 may be provided with a serrated groove (not shown in the figure) that matches the circumferential surface of the outer flange 522. When the outer flange 522 abuts against the annular retaining ring 5121, the outer flange 522 is located in the serrated groove. By utilizing the matching of the serrated circumferential surface of the outer flange 522 with the serrated groove, the injection plug 52 can be rotated when the outer flange 522 is rotated, so as to pull out the injection plug 52.

[0107] In the first and second embodiments described above, liquid is injected into the waterproof vapor chamber 30 after the injection plug 52 is completely pulled out. In other embodiments, an injection channel may be provided on the injection plug 52, through which liquid is injected into the waterproof vapor chamber 30 when the injection plug 52 is pulled out halfway. The specific implementation method is as follows.

[0108] like Figure 14 and Figure 15 As shown, in the multi-layered watch 100 with waterproof function provided in the third embodiment of the present invention, the injection plug 52 is provided with two sealing rings, namely a first injection sealing ring 541 and a second injection sealing ring 542. The first injection sealing ring 541 and the second injection sealing ring 542 are arranged along the axial direction of the injection plug 52, and the first injection sealing ring 541 is closer to the waterproof cavity 30 in the multi-layered watch 100 than the second injection sealing ring 542. The injection plug 52 is provided with an injection channel 520.

[0109] The injection channel 520 has an injection inlet 520a and an injection outlet 520b. The injection outlet 520b is located on the end face of the sealing end 52a of the injection plug 52, and the injection inlet 520a is located on the circumferential surface of the injection plug 52 and is located between the first injection sealing ring 541 and the second injection sealing ring 542.

[0110] like Figure 14 As shown, when the injection channel 50 and the injection plug 52 are in a sealed state, the first injection sealing ring 541, the second injection sealing ring 542 and the injection inlet 520a are all located in the injection channel 50, and the injection channel 50 is sealed by the first injection sealing ring 541 and the second injection sealing ring 542.

[0111] When liquid needs to be injected, such as Figure 15 As shown, the injection plug 52 is moved outward, and the injection channel 50 and the injection plug 52 are in an open state. At this time, the second injection sealing ring 542 and the injection inlet 520a of the injection channel 520 are located outside the injection channel 50, that is, the second injection sealing ring 542 and the injection inlet 520a of the injection channel 520 are exposed on the outside of the multi-layer structure watch 100. The needle is inserted through the injection inlet 520a of the injection channel 520 to inject liquid. The liquid enters the waterproof cavity 30 through the injection outlet 520b of the injection channel 520, so that the liquid injection operation can be performed without completely pulling out the injection plug 52, thus avoiding the loss of the injection plug 52.

[0112] Furthermore, a limiting annular groove 501 can be provided on the injection channel 50. When the injection plug 52 moves outward from the multi-layer structure watch 100 so that the first injection sealing ring 541 is located in the limiting annular groove 501, the second injection sealing ring 542 and the injection inlet 520a of the injection flow channel 520 are located outside the injection channel 50. By using the limiting annular groove 501, the user can perceive that the injection plug 52 has moved to a position where liquid injection can be performed, thereby avoiding the injection plug 52 being completely pulled out.

[0113] The multi-layered watch 100 provided in the fourth embodiment of the present invention is a further improvement on the foregoing embodiments. For example... Figure 16 As shown, a gas-retaining groove 301 for containing gas is provided on the side wall of the waterproof vapor chamber 30, and the gas-retaining groove 301 is located at the top of the waterproof vapor chamber 30. Here, it can be understood that the top of the waterproof vapor chamber 30 refers to the end of the waterproof vapor chamber 30 closest to the front of the watch, i.e., the watch crystal.

[0114] By utilizing the top receiving groove 301, when the liquid in the waterproof vapor chamber 30 is not full, the gas in the waterproof vapor chamber 30 can automatically enter the top receiving groove 301 of the waterproof vapor chamber 30, thereby preventing the gas in the waterproof vapor chamber 30 from obstructing the time display.

[0115] In this embodiment, the receiving groove 301 is annular along the circumference of the watch so that it can accommodate some gas on all four sides. The receiving groove 301 is disposed on the outer frame 22 for ease of processing and manufacturing.

[0116] Furthermore, the inner surface 21a of the outer mirror 21 is closer to the inner shell 1 than the top surface 301a of the receiving groove 301, so that the gas in the waterproof vapor chamber 30 can better enter the receiving groove 301 and avoid contact with the inner surface 21a of the outer mirror 21, thus avoiding affecting the time display. The top surface 301a of the receiving groove 301 is recessed upwards to further better contain the gas within the receiving groove 301.

[0117] In the multi-layered watch 100 with waterproof function provided in the fifth embodiment of the present invention, the difference from the previous embodiments lies in the structure of the pressure relief device 6. For example... Figure 17 and Figure 18 As shown, in this embodiment, the pressure relief device 6 includes a pressure relief column 61 and a pressure relief crown 612. The pressure relief column 611 and the pressure relief crown 612 are two separate components that can be separated, meaning they are not connected as a single structure. The pressure relief column 611 and the pressure relief pipe 63 can each be provided with a sealing structure to the pressure relief channel 60, or one of them can be provided with a sealing structure to the pressure relief channel 60.

[0118] Compared to the previous embodiments, the only difference in this embodiment of the pressure relief crown 612 is the matching structure between the central column 6123 and the pressure relief column 611. The structural similarities will not be described again.

[0119] More specifically, a first sealing ring 661 is provided between the central post 6123 of the pressure relief crown 612 and the pressure relief channel 60, and a second sealing ring 662 is provided between the first limiting part 6111 of the pressure relief post 611 and the pressure relief channel 60. In this embodiment, both the first sealing ring 661 and the second sealing ring 662 are positioned on the inner wall of the pressure relief channel 60. When the pressure relief component 61, i.e., the pressure relief post 611 and the pressure relief crown 612, moves along the pressure relief channel 60, it can contact or gap-fit ​​with the second sealing ring 662 and the first sealing ring 661, thereby realizing the conversion between the sealed state and the open state. Here, depending on the different structures of the pressure relief crown 612 and the pressure relief post 611, the first sealing ring 661 and the second sealing ring 662 of the sealing structure can be provided at other parts of the pressure relief crown 612 and the pressure relief post 611.

[0120] In this embodiment, as Figure 17 As shown, when the pressure relief device 6 is in a sealed state, the pressure relief crown 612 is tightened at the opening of the pressure relief channel 60. The circumferential surface of the central post 6123 of the pressure relief crown 612 contacts and engages with the first sealing ring 661, and the pressure relief post 611 contacts the second sealing ring 662, so that the pressure relief component 61 and the pressure relief channel 60 are in a sealed engagement state. Furthermore, the pressure relief crown 612 blocks the pressure relief outer end 611a of the pressure relief post 611 to restrict the movement of the pressure relief post 611, thus locking both the pressure relief post 611 and the pressure relief crown 612 and the pressure relief channel 60 in a sealed state.

[0121] like Figure 18 As shown, when the pressure relief crown 612 is loosened, it moves outwards towards the multi-layered watch 100, causing it to misalign with the first sealing ring 661. This creates a gap fit between the two, releasing the seal between the pressure relief crown 612 and the pressure relief channel 60. Simultaneously, a gap is formed between the pressure relief crown 612 and the pressure relief column 611. If the pressure inside the waterproof cavity 30 is too high, it will push the pressure relief column 611 outwards. After moving a certain distance, the pressure relief column 611 is misaligned with the second sealing ring 662, and the two are in a gap fit. This opens the seal between the pressure relief column 611 and the pressure relief channel 60, allowing pressure relief. When the pressure drops to a certain level, the pressure relief column 611 moves towards the waterproof cavity 30 under the action of the pressure relief elastic element 62. The pressure relief column 611 contacts the second sealing ring 662, sealing the pressure relief column 611 and the pressure relief channel, stopping the pressure relief.

[0122] In this embodiment, the pressure relief column 611 and the pressure relief crown 612 are two separate components that can be separated. When the pressure relief crown 612 rotates, it will not cause the pressure relief column 611 to rotate or move, so as to avoid affecting the elastic structure. When the pressure relief column 611 moves along the pressure relief channel 60, the pressure relief column 611 will also not cause the pressure relief crown 612 to move, so as to ensure the flexibility of the movement of the pressure relief column 611 and enable it to release pressure in a timely manner.

[0123] like Figure 19 , Figure 20 As shown, in the multi-layer structure watch 100 provided in the sixth embodiment of the present invention, the first sealing ring 661 is disposed on the side of the second limiting part 6011 near the pressure relief crown 612. The inner diameter of the first sealing ring 661 is larger than the outer diameter of the pressure relief outer end 611a of the pressure relief column 611, so that the first sealing ring 661 and the pressure relief outer end 611a always maintain a clearance fit. Figure 19 As shown, when the pressure relief device 6 is in a sealed state, the first sealing ring 661 is pressed between the second limiting part 6011 and the inner end of the central column 6123, so that the pressure relief crown 612 and the pressure relief channel 60 are in a sealed state. When pressure relief is required, loosen the pressure relief crown 612, as shown. Figure 20 As shown, the central column 6123 is separated from the first sealing ring 661, and the pressure relief crown 612 and the pressure relief channel 60 are in an open state. When the pressure in the waterproof air chamber 30 is greater than the elastic force of the pressure relief elastic element 62, the pressure relief column 611 moves to relieve pressure.

[0124] In the multi-layered watch 100 with waterproof function provided in the fifth and sixth embodiments of the present invention, the central post 6123 of the pressure relief crown 612 is sealed to the pressure relief channel 60 by a first sealing ring 661. Alternatively, a sealing structure can be provided in other parts of the pressure relief crown 612 to achieve the sealing of the pressure relief channel 60. For example, a sealing structure can be 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 tube 63, or a sealing structure can be provided between the end face of the pressure relief ring 6122 and the outer wall of the outer frame 22.

[0125] In the pressure relief device 6 of the aforementioned embodiment, steam is released and pressure is relieved through the gap between the pressure relief channel 60 and the pressure relief component 61 to achieve relatively gentle pressure relief while preventing a large amount of liquid from flowing out. In the multi-layer structure watch 100 provided in the seventh embodiment of the present invention, the main difference from the aforementioned embodiments lies in the pressure relief device 6. For example... Figure 21 and Figure 22As shown, the pressure relief column 611 and pressure relief crown 612 of the pressure relief device 6 are two separate components that can be separated. The pressure relief column 611 has a through pressure relief channel 610 arranged along the axial direction. A sealing plug 64 is provided at the pressure relief outer end 611a of the pressure relief column 611. The sealing plug 64 includes an integrally formed sealing column 641 and a sealing edge 642. The sealing column 641 is inserted and sealed in the pressure relief channel 610. The sealing edge 642 abuts against the pressure relief outer end 611a and against the second limiting part 6011. When the pressure relief device 6 is in a sealed state, the sealing edge 642 is pressed between the pressure relief crown 612 and the second limiting part 6011, thereby realizing the sealed connection between the pressure relief component 61 and the pressure relief channel 60.

[0126] The outer periphery of the sealing edge 642 is fitted with the inner wall of the pressure relief channel 60 through a clearance, allowing pressure relief to be achieved. When pressure relief is required, the pressure relief crown 612 is loosened. If the pressure inside the waterproof vapor chamber 30 is too high, it will push the pressure relief column 611 toward the pressure relief crown 612. The pressure relief column 611 drives the sealing plug 64 to move, and the sealing edge 642 of the sealing plug 64 separates from the second limiting part 6011, so that the pressure relief channel 60 is in the open state, and pressure relief is achieved through the gap between the sealing plug 64 and the inner wall of the pressure relief channel 60.

[0127] After opening the pressure relief crown 612, the sealing plug 64 can be pulled out, and pressure can be quickly released using the pressure relief channel 610. At the same time, liquid can also be injected into the waterproof cavity 30 using the pressure relief channel 610, so the injection device 5 is not required on the multi-layer structure watch 100.

[0128] To facilitate the removal of the sealing plug 64, as in the eighth embodiment of the present invention, a multi-layered watch 100 with waterproof function is provided, such as... Figure 23 As shown, the sealing plug 64 is also provided with a pull ring 643, and the sealing edge 642 is located between the pull ring 643 and the sealing post 641. The pressure relief crown 612 is provided with a clearance groove 6120 corresponding to the position of 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 easily removed using the pull ring 643.

[0129] In the above embodiments, the multi-layer watch 100 is equipped with both an injection device 5 and a pressure relief device 6. The injection device 5 and the pressure relief device 6 can be respectively located at the 10 o'clock and 8 o'clock positions, which can make the overall shape of the multi-layer watch 100 balanced and not appear abrupt. In other embodiments, only the injection device 5 can be provided. For example, in the first embodiment, only the injection device 5 is provided. When pressure relief is needed, the injection plug 52 can be opened to achieve pressure relief. Or, in the second embodiment, the injection inlet 520a of the injection channel 520 is exposed to achieve pressure relief. As another implementation method, the multi-layer watch 100 may not be equipped with the injection device 5 and the pressure relief device 6. Before sealing and assembling the multi-layer watch 100, liquid can be injected into the waterproof cavity 30 before sealing and assembling the multi-layer watch 100. When the waterproof performance and pressure resistance of the multi-layer watch 100 are good, it is not necessary to provide the pressure relief device 6.

[0130] In the above embodiments, the inner case 1 and outer case 2 of the multi-layered watch 100 with waterproof function are independently separable components. As another embodiment, some components between the inner case 1 and outer case 2 can be integrated as a whole. For example, the inner mirror 11 of the inner case 1 and the outer mirror 21 of the outer case 2 can be integrally formed to prevent gas from obstructing the time display area. The inner bottom cover 13 of the inner case 1 and the outer bottom cover 23 of the outer case 2 can also be integrally formed, so that the waterproof cavity 30 can be sealed to the inner case 1 during assembly.

[0131] In the above embodiments, the support member is rod-shaped and connected between the inner middle frame and the outer middle frame. In other embodiments, the support member can also be plate-shaped and disposed between the endoscope and the outer endoscope, as well as between the inner bottom shell and the outer bottom shell, as long as it can realize the connection between the inner shell and the outer shell.

[0132] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention. Those skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope defined in the claims.
