[specific embodiment]

See also shown in Fig. 2 and 3, the utility model is a kind of Dewar bottle, and it is made up of members such as bottle 1, top cover 2, bottom 3, head cap 4, pedestal 5, first guide rod 61, first spring 71, first piston 81, second guide rod 62, second spring 72, spheroid 9, second piston 82 and bottle caps 10.

Wherein, the bottle shell 12 that described bottle 1 comprises glass liner 11 and is coated on glass liner 11 peripheries is provided with screw thread 111 in described glass liner 11 upper ends, and described top cover 2 is to screw togather on the screw thread 111 that is installed on glass liner 11.Described bottle cap 10 is the upper end that is sheathed on bottle 1.Bottom in described bottle shell 12 is equipped with one first through hole 13.And described top cover 2 and bottom 3 are installed on the two ends up and down of bottle 1 respectively.Be provided with a vertical guide channel 21 in top cover 2, realize sealing in the glass liners 11 thereby be provided with a gasket seal 22 between itself and the glass liner 11.Described bottom 3 is immobilizated on the glass liner 11, and its bottom is provided with second through hole 31.Described head cap 4 is sheathed on first guide rod 61 and can pushes first guide rod 61 and moves downward, and it is provided with a vertical guiding part 41, and this guiding part 41 matches with the guide channel 21 of top cover 2.Pedestal 5 is to be immobilizated on the top cover 2, and described first spring 71, first piston 81, second guide rod 62, second spring 72 and ball 9 are installed in the pedestal 5 successively and the liquid in the bottle 1 can be extruded.Described first piston 81 can be up and down in pedestal 5, and it separates pedestal 5 is first receiving space 51 and second receiving space 52.Described first spring 71 is positioned at first receiving space 51 and its two ends are connected to respectively on first guide rod 61 and the first piston 81.Described second spring 72 is positioned at second receiving space 52 and its two ends are connected to respectively on second guide rod 62 and the spheroid 9, and in the present embodiment, spheroid 9 is specially a baton round.

Further, described second piston 82 comprises a cylindrical main part 821, is respectively equipped with an abutting part 822 in the two ends up and down of described main part 821.Described abutting part 822 is the setting of awl wing-shaped structure, it is connected on the inwall of glass liner 11, borrow this awl wing abutting part 822, second piston 82 can closely cooperate with glass liner 11 inwalls and be seamless, and it is better to bore wing abutting part 821 guidance quality in columniform glass liner 11, makes second piston 82 flexibly movable.Be provided with an air chamber 32 between described second piston 82 and bottom 3, first through hole 13 of above-mentioned bottle shell 12, second through hole 31 of bottom 3 are connected with this air chamber 32.

The principle of work of Dewar bottle of the present utility model is as follows:

1. push head cap 4 downwards, it drives first guide rod 61 and moves downward, and described first guide rod 61 promotes first spring 71 and first piston 81 moves down; Described first piston 81 compresses second guide rod 62 downwards and transfers the pressure on second spring 72; Second spring 72 will compress the spheroid 9 of bottom, cause the air of second receiving space 52 to be compressed, and the air of second receiving space 52 is discharged to outside the bottle by second guide rod 62 and first guide rod 61;

2. head cap 4 resets, and first spring 71 and second spring 72 also restore to the original state, and first piston 81 can not enter in second receiving space 52 extraneous air 62 sealings of second guide rod, and at this moment, the gas of second receiving space 52 thins out, and vacuum layer occurs.Under atmospheric effect, spheroid 9 is adsorbed in second receiving space 52, and the liquid of splendid attire is adsorbed into second receiving space 52 immediately in the glass liner 11.Spheroid 9 resets when liquid is full of second receiving space 52.But make the inside and outside both sides build-up of pressure of second piston 82 poor because of the liquid in the glass liner 11 enters second receiving space 52, at this moment, second piston 8 moves up under the traction of bar pressure, finally makes the atmospheric value of second piston, 82 inside and outside both sides identical;

3. repeat above-mentioned push action, the liquid in second receiving space 52 is squeezed, and this liquid is had to be extruded by first guide rod 61, second guide rod 62 and head cap 4 from second receiving space 52.

Dewar bottle of the present utility model is by being provided with second piston 82 in the bottom, utilize the upwards interior liquid of lifting bottle of second piston 82, and utilizing draught head that the liquid in the bottle is extruded, this project organization is simple, easy to use, health, and the liquid in the bottle can be extruded fully.Simultaneously, second piston 82 is provided with the wing abutting part 821 of awl, and to touch area little with bottle graft, guarantee under air pressure, to promote 82 motions of second piston, and adjust the position, make it seamless with cooperating of glass liner 11 by this abutting part 822, sealing property is better, and steering capability is also relatively good.

The above specific embodiment only is the preferred embodiment of this creation, not in order to limiting this creation, all in this creation spirit and principle within made any modification, be equal to replacement, improvement etc., all should be included within the protection domain of this creation.
