Diving watch assembly

摘要

A diving watch assembly includes an internal airtight and waterproof space formed by a housing, an upper cover, a transparent plate and a lower cover, and an air pressure watch core, a water pressure watch core and a dial disc installed in the internal airtight and waterproof space. The air pressure watch core is adapted to drive a first pointer, and the water pressure watch core is adapted to drive the second pointer. The air pressure (air amount) scale and the water pressure (water amount) scale are respectively indicated by the first pointer and the second pointer on the same dial disc.

1. A diving watch assembly, comprising:
a housing, being a hollow cylindrical structure, including an upper opening shaped as a trumpet opening at an upper end of the housing, a lower opening at a lower end of the housing, an annular inner flange at an inner periphery surface of the housing, and an air pressure tube opening at a side surface of the housing; an upper cover, being a hollow annular structure, adapted to fasten at the upper opening of the housing to allow the upper cover and the housing to be closely fastened to each other; a transparent plate, assembled between the upper cover and the housing, including an annular sealing packing between a lower portion of the transparent plate and the upper opening of the housing; a lower cover, adapted to fasten at the lower opening of the housing, a plurality of water pressure holes being provided at a surface of the lower cover, a water pressure film being provided between the lower cover and the lower opening of the housing to cause the lower cover and the housing to be closely fastened to each other; an air pressure watch core, installed in an upper space of the housing, including a first pointer at an axle of the air pressure watch core and an air inlet at a side of the air pressure watch core, adapted to be exactly placed into the air pressure tube opening of the housing, connected to a gas cylinder through externally connected air pressure connector and an air pressure tube, for sensing a pressure of air residual in the gas cylinder; a water pressure watch core, installed in a space between the inner flange and the lower opening of the housing, including a second pointer at an axle of the water pressure watch core, the water pressure watch core having an upper end surface in contact with the inner flange and a lower end surface covered by the water pressure film, a sensing assembly in the water pressure watch core adapted to be driven by the water pressure film and for sensing a diving depth; and a dial disc, being a plate-like structure, including a central planar portion, an outer ramp portion, an axle opening provided at a central end of the planar portion for penetrating the axle of the air pressure watch core, an air pressure (air amount) scale at a surface of the planar portion, a circular cut channel between the planar portion and the ramp portion for penetrating the second pointer of the water pressure watch core, and a water pressure (water depth) scale at a surface of the ramp portion; wherein, the air pressure watch core is adapted to drive the first pointer according to the air pressure sensed, and the water pressure watch core is adapted to drive the second pointer according to the water pressure sensed, to indicate air residual in the gas cylinder and diving depth of a diver by the first pointer and the second pointer on the same dial disc, respectively.
