Brief description of the drawings
Fig. 1 is helium gas emission structure diagram.
Embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without creative efforts
All other embodiments obtained, shall fall within the protection scope of the present invention.
Fig. 1 is helium gas emission structure diagram.The utility model is reversely using the helium principle smaller than hydrone come real
The discharge of helium is realized on the premise of present waterproof.
Helium gas emission structure mainly includes watchcase component and gas deflation assembly, and gas deflation assembly includes exhaust plug 11, air bleeding valve
Core is arranged on the exhaust passage 10 of watchcase component, and exhaust plug 11 and the inner wall of exhaust passage 10 leave gap, exhaust passage
Inner wall be equipped with 2 the first sealing rings 4, exhaust plug is equipped with the groove 5 to match with the first sealing ring, exhaust plug 11
Exhaust knob 1, spool extension are equipped with the head end along the spool extension 2 for deviating from the exhaust passage, spool extension 2
The inner wall that screw thread and exhaust passage are equipped with close to cephalic par matches in the internal thread of the endface position away from exhaust passage.
The center of exhaust plug 11 is equipped with cylindrical hole 14, and cylindrical hole 14 is along cavity direction end in wrist-watch
Relative aperture cylindrical hole is small；T-shaped banking pin 13 is further included, the big portion of T-shaped banking pin 13 is arranged in cylindrical hole, with circle
Cylindricality through hole 14 is fixed by screws on watchcase component to matching, the end of thin portion through the cylindrical hole of T-shaped banking pin.
Compression spring 3 is additionally provided with cylindrical hole.
Due to the spacing and guiding role of T-shaped banking pin 13, exhaust plug 11 is only possible to along axial location limited
Apart from interior movement.After all parts are installed, the normal condition of wrist-watch is to screw rotary rowed cyclone button 11, drives air bleeding valve
The compression compression spring of core 11 is moved towards wrist-watch cavity position, and the first sealing ring 4 misplaces with groove 5 under the state, under the state
Exhaust plug 11 extrudes 4 most serious of the first sealing ring, therefore the waterproof effect under the state is optimal, similarly helium be also not easy into
Enter the inner cavity of wrist-watch.The state is kept in the when submersion watch of diving, when the depth of dive is deep enough, outside pressure is enough helium
Gas enters inner cavity through water proof ring, and chamber pressure also progressively increases.
During upper dive, it is by rotary rowed cyclone button 11 to dive on to certain altitude, drives the first sealing ring 4 outside
Movement, when the first 4 just alignment indentation of sealing ring, groove is also to maintain certain compressive deformation to the first sealing ring 4, still
It can keep basic waterproof.Pressure in the state lower inner cavity is more than the pressure of outside and is enough internal helium through anti-
Hydrosphere discharges inner cavity, and reaching both waterproofs has the effect that can arrange helium.
Above disclosed is only a kind of the utility model embodiment, cannot limit the utility model with this certainly
Interest field, one of ordinary skill in the art will appreciate that realize all or part of flow of above-described embodiment, and according to this reality
The equivalent variations made with new claim, still fall within the scope that utility model is covered.
