Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In some special occasions or special operations, such as firefighters, the working environments are relatively various, and environments with high temperature, high humidity or low temperature, high humidity and the like can exist, and under the special environments, the requirements on the accuracy and convenience of the meter reading are higher, and the meter reading is required to be very clear and easy. However, in these environments, the problem of fogging of the watch tends to occur on the surface, and therefore, for this type of watch for special use, it is generally required that the airtightness of the movement is very good, and at the same time, it is generally required that the movement is filled with an inert gas, such as argon. However, the air-tight design is good, and the water vapor infiltration is inevitable, especially for a long time. There is therefore also a need for the movement to be dry. It is difficult for ordinary users to actually determine whether moisture exists in the interior of the container and the container needs to be dried. These problems, if highlighted in the actual rescue, would have unpredictable consequences. Therefore, whether water vapor enters the inside of the watch or not needs to be displayed in a very simple mode, whether the drying agent inside the watch is invalid or not needs to be displayed, the drying agent can be replaced under the condition that the inside of the machine core is sealed, if the drying agent cannot be replaced under the condition that the inside of the machine core is sealed, the replacement process enables the argon gas filled in the original inside to flow into the common space, the argon gas is required to be refilled into the watch, a professional argon gas filling device is needed, and the method obviously cannot be achieved for common consumers.
FIG. 1 is a general schematic view of a special wristwatch adapted for use by firefighters; FIG. 2 is an exploded view of a special wristwatch adapted for use by firefighters; the invention particularly designs a special wristwatch suitable for firefighters, which comprises a wristwatch main body E and a watchband D, wherein the side surface of the wristwatch main body E is provided with 1 drying system A with an isolation observation window, 1 air inlet valve B with an air inlet valve protection device, 1 exhaust valve system G, 1 timing rotating handle F and 1 watch handle C. The wristwatch body E mainly comprises a watch mirror D102, an inner shadow D103, a rotatable inner shadow D104, a movement D105 and a bottom cover D101.
In order to realize the automatic drying of the wristwatch, in a production link or a professional maintenance link, dry argon is injected into the inner part of the movement, so that gas in the inner part of the movement is discharged, and the inner part of the movement is kept sealed. In order to realize that the interior of the wristwatch can be automatically dried and prevent the problem that the interior of the wristwatch is damp after long-time use, a drying system mounting hole and a drying system with an isolated observation window are arranged on one side surface of a wristwatch main body, wherein the drying system comprises a cylindrical drying agent container A205, a drying agent A204, a sealing spring A402, a closed valve core A401, a drying handle pipe A404 and a drying inner closed ring A403, the drying system mounting hole is provided with a three-stage aperture which is gradually reduced from the outside to the inside and is respectively a first-stage aperture section A301, a second-stage aperture section A304 and a third-stage aperture section A305; the desiccant container is hollow and provided with a desiccant container cavity A202, two ends of the desiccant container are opened, one end of the outer side of the desiccant container is sealed through an inner glass lens A201, the outer side of the desiccant container is provided with external threads, and the inner side of the first-stage aperture section A301 is provided with internal threads matched with the external threads of the desiccant container A205; one end of the drying handle pipe A404 is provided with a connecting hole matched with the closed valve core A401, and the sealing spring A402 is limited between the closed valve core A401 and the second-stage aperture section A304 by the closed valve core A401; the aperture of the small end of the drying handle pipe A404 is slightly smaller than that of the third-stage aperture section A305, and the aperture of the large end of the drying handle pipe A404 is larger than that of the third-stage aperture section; the drying handle pipe A404 is sleeved with a drying inner sealing ring A403 from the inner side of the wristwatch, then penetrates through a third-stage aperture section A305 from the inner side of the watch core, is connected with a sealing valve core A401 at the other side, and compresses a sealing spring A402, and when no external force is applied to the end part of the sealing valve core, the end parts of the sealing valve core A401 and the first-stage aperture section have a stroke not smaller than the thickness of the drying inner sealing ring.
When the end part of the closed valve core has no external force, the closed valve core A401 is pushed outwards by selectively controlling the compression sealing spring A402, and the drying pipe A404 is driven to extrude the drying inner closed ring A403 to realize the internal sealing of the machine core and is not communicated with the drying agent accommodating cavity A202. I.e., the entire desiccant receiver a205 is removed externally and the desiccant in the desiccant receiving chamber a202 is freely replaced. The desiccant can be replaced under the condition of ensuring the sealing state of the machine core. That is, fig. 4 is a front sectional view of a desiccant-replacement state of a part of the wristwatch in which the drying system is installed; FIG. 5 is a perspective cross-sectional view of a portion of a wristwatch with a drying system installed in a replacement desiccant.
The design structure can safely realize the replacement of the drying agent; it is also desirable to achieve efficient operation of the desiccant at ordinary times. Fig. 3 is a sectional view of a part of a wristwatch provided with a drying system in a dry state, and two problems need to be solved for realizing the same, wherein the first problem is that a drying agent needs to be provided with a gas connecting channel with an inner cavity of a movement, and the part is realized by matching a drying agent container A205, a sealing spring A402, a sealed valve core A401, a drying handle pipe A404 and a dry inner sealed ring A403. When no external force is applied to the end part of the sealing valve core, the sealing valve core A401 and the end part of the first-stage aperture section have a stroke which is not less than the thickness of the sealing ring in the drying process. The desiccant container A205 is screwed inwards, the sealing valve core A401 is further pressed inwards to the sealing spring A402, the drying handle pipe A404 is pushed to move inwards, and when no external force is applied to the end part of the sealing valve core, the stroke of the sealing valve core A401 and the end part of the first-stage aperture section is not less than the thickness of the sealing ring in the drying process. Therefore, the drying handle pipe A404 is pushed to fall off completely to extrude the drying inner closed ring A403, so that the inner cavity of the machine core is communicated with the outer side of the inner cavity of the machine core through the second-stage aperture section A304 and the third-stage aperture section A305, and at least one groove A405 is arranged on the end part of the closed valve core and is used for communicating the drying system mounting hole with the drying agent accommodating cavity A202, so that the drying agent in the drying agent accommodating cavity A202 can be kept in a normal drying state. After the watch is completely assembled, the desiccant container A205 is in a screwed and fixed state, and the normal automatic drying function is kept. When the drying agent needs to be replaced, the drying agent can be conveniently replaced only by unscrewing the drying agent container A205, and the drying agent can be rotated back after the drying agent container A is replaced.
Another problem to be solved is the sealability in a normally dry state. A first sealing ring A203 is further arranged on the connecting part of the desiccant container A205 and the drying system mounting hole, and when the desiccant container A205 is in a screwing and fixing state, the first sealing ring A203 is extruded to realize first-stage sealing. Since normal use is normal, the sealing requirements for this condition are higher, and therefore a second layer of seal is also added to the outer layer.
An outer sealing ring groove A105 is concentrically arranged on the side face of the wristwatch main body at the periphery of the drying agent container, and an outer sealing ring A104 is arranged on the outer sealing ring groove to realize second-stage sealing. An outer layer observation window is additionally arranged on the outer side of the drying agent container and comprises an outer glass lens A103 and an observation window support A101, and the diameter of the outer glass lens is larger than that of the inner glass lens and is arranged concentrically with the inner glass lens; an outer observing sealing ring A102 is arranged between the outer glass lens and the observation window bracket. The observation window bracket is fixed outside the desiccant container A205 through the screw column group A106, and meanwhile, the outer sealing ring A104 is extruded to realize a second-stage sealing ring. And two-stage sealing is realized. When the desiccant needs to be replaced, the outer layer observation window is detached, then the desiccant container A205 is detached, and then the desiccant needs to be replaced. After the drying agent is replaced, the drying agent container A205 is installed in place, and then the observation window bracket is installed, so that the operation is simple and convenient.
There is also a need to solve a problem as to how the user can determine whether the desiccant inside needs to be replaced. The whole volume of actual wrist-watch is very little, therefore its space is limited, and the drier volume that it can hold is very little, consequently not easily observe, and this technical innovation chooses for use the drier for absorbing moisture and discolours the drier. So that if the interior of the machine core is wetted, the desiccant can automatically absorb moisture to realize automatic drying, and the desiccant can change color after absorbing moisture. Therefore, whether the drying agent needs to be replaced can be judged by observing whether the drying agent is discolored or not. Since the desiccant is disposed in the desiccant container a205, in order to make the internal dryer visible from the outside, one end of the outside of the desiccant container chamber a202 is sealed by an inner glass lens a201 through which the desiccant is visible. Because the desiccant volume is too small, in order to further facilitate the user to observe the desiccant more conveniently and intuitively, an outer layer observation window is added, and the inner glass lens and the outer glass lens are both convex lenses with the surfaces facing the movement as planes. The diameter of the outer glass lens A103 on the outer layer observation window is larger than that of the inner glass lens and the outer glass lens are arranged concentrically, and the inner glass lens and the outer glass lens are both convex lenses with planes facing the movement surface. The two-stage lens is used to magnify the internal desiccant for presentation to the user. So that the user can easily observe the internal desiccant, and the desiccant is found to be invalid and replaced in time at the first time.
