Description

Vacuum self-priming bottle

Technical field:

The utility model relates to a kind of vacuum self-priming bottle.

Technical background:

The packing container of existing liquid daily-use chemical industry such as shampoo, shower cream etc. mostly is to establish the piston pump of a band suction pipe at an upper portion thereof and stretch in the container suction pipe with the liquid sucking-off in the container, the inside of this packing container must be communicated with the pressure inside and outside the equalizing reservoir with the atmosphere in the external world, otherwise can be because of the inwardly shrinkage distortion of in-to-in negative pressure with regard to can not inhaling liquid or container; Its shortcoming is to cause in the container easily as the volatilization of materials such as spices, has influenced the result of use of product, and when the interior amount of liquid of bottle hour, bottle can not be swung to use.

Summary of the invention:

The purpose of this utility model be for solve in the bottle that exists in the existing liquid package container material volatile, can not be inverted the problem of use, and provide a kind of simple in structure, without suction pipe, can be inverted the vacuum self-priming bottle of use.

Technical scheme:

A kind of vacuum self-priming bottle comprises bottle, head and spring, and the inner chamber that it is characterized in that described bottle is cylindric, and the bottle intracavity diameter matches with sliding plug, and sliding side beyond the Great Wall communicates with atmosphere, constitutes reservoir compartment between sliding plug and the bottle intracavity; Bottle top is provided with the plunger shaft of built-in piston, is provided with the feed liquor check valve between plunger shaft bottom and the described reservoir compartment; The bottle upside is fixed with locking closure, and locking closure central authorities are provided with outer guide pipe; The interior guide pipe that communicates with liquid outlet channel in the described head is entangled by the outer guide pipe of locking closure, and both slips match; Described liquid outlet channel and described in liquid outlet and valve head between the guide pipe top constitute the fluid check valve; Described piston upside is provided with the sebific duct that stretches in the described interior guide pipe, is provided with the sealing wing of annular between sebific duct and the interior guide pipe, and this sebific duct lower end communicates with plunger shaft, the upper end links to each other with described valve head.

Described vacuum self-priming bottle is characterized in that sebific duct and the described valve head on the described piston is conjoined structure.

Described vacuum self-priming bottle, it is characterized in that described feed liquor check valve is made of some through holes of valve block and plunger shaft bottom, valve block central authorities are provided with the discount that stretches into bottle intracavity, and the valve block of annular is positioned at plunger shaft and shelters from the described through hole that is distributed in annular valve block downside.

Beneficial effect, owing to adopted technical scheme described in the utility model, make in the bottle liquid when discharging when pushing head repeatedly by the liquid outlet channel on the head, owing to produce negative pressure in the bottle, so the sliding plug that will be positioned at bottle is simultaneously inhaled and is made sliding plug upward movement till bottle liquid is sucked to bottle, bottle inside that is to say that vacuum self-priming bottle described in the utility model is the effect that reaches equilibrium air pressure with effective volume in the decreased locomotion bottle of sliding plug, so need not communicate with the external world; Thereby avoided bottle interior material to evaporate in the atmosphere, guaranteed the result of use of material in the bottle and can prolong the effective life of bottle interior material, even and the bottle inversion do not influenced its use yet.

Description of drawings:

It shown in the accompanying drawing inner structure scheme drawing of an embodiment of vacuum self-priming bottle described in the utility model.

Among the figure 13, bottom, 12, sliding plug, 1, bottle, 102, through hole, 101, plunger shaft, 2, locking closure, 3, piston, 201, outer guide pipe, 5, spring, 304, the sealing wing, 6, head, 302, side opening, 301, valve head, 603, liquid outlet, 603, liquid outlet channel, 602, interior guide pipe, 303, sebific duct, 20, stop gear, 111, valve block, 11, discount, 131, the balance pore.

The specific embodiment:

See shown in the accompanying drawing, described vacuum self-priming bottle, comprise bottle 1, head 6 and spring 5, the inner chamber of bottle 1 is cylindric, the bottle intracavity diameter matches with sliding plug 12, bottle body bottom is provided with bottom 13, balance pore 131 on the bottom 13 makes sliding plug 12 outsides communicate with atmosphere, when depressing head 6, valve head 301 separates with liquid outlet 603 on the head, the fluid one-way valve opens, piston 3 increases with plunger shaft 101 interior pressures that the bottle upside constitutes, liquid in the plunger shaft can only be through sebific duct 303, the side opening 302 on sebific duct top, liquid outlet 603, liquid outlet channel 601 ejections, after unclamping the hand of pushing down head, head 6 upwards resets under the effect of spring 5, liquid outlet 603 contacts with valve head 301 and liquid outlet 603 is closed, the fluid closed check valve, and because valve head 301 links to each other with piston 3, so piston is subjected to power upwards, plunger shaft 101 produces negative pressure and valve block 111 is inhaled upwards (valve block central authorities are fixed on the plunger shaft bottom by discount 11), and open the feed liquor check valve, and the reservoir compartment in the bottle also produces negative pressure and will slide plug 12 upwards to be inhaled, and the liquid in the reservoir compartment is inhaled in the plunger shaft till the limited mechanism of head 20 is spacing.

Wherein piston, sebific duct, the ring seal wing and valve head are conjoined structure.
