Abstract

The utility model relates to a liquid-packaging container, in particular to a vacuum pump of emulsion. The utility model solves the problem with the existing daily-use industrial containers that the using effects of the substances in the containers are influenced owing to easy volatilization because the inside of the container must be in communication with the air. The utility model is composed of a button, a piston pump and a bottle body. The utility model is characterized in that a sliding plunger of which the exterior diameter is in engagement with the internal diameter of the bottle body and is capable of sliding in the bottle body, besides liquid raw materials are contained in the space of bottle body between the sliding plunger and the pump body. A foundation is arranged at the bottom of the bottle body, and an opening for balancing air-pressure is opened on the foundation.

Description

Emulsion vacuum pump

Technical field:

The utility model relates to a kind of container, particularly a kind of emulsion vacuum pump.

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 the interior volatilization as materials such as spices of container easily, has influenced the result of use of product.

Summary of the invention:

Technical matters, the purpose of this utility model just provides a kind of lotion pump without suction pipe, it solved exist in the existing daily-use chemical industry container because of internal tank must communicate with atmosphere cause material in the container volatile, influenced the problem of the result of use of material in the bottle.

Technical scheme:

The purpose of this utility model is achieved in that a kind of emulsion vacuum pump, comprises head, piston pump, bottle; It is characterized in that in bottle, being provided with the sliding plug that an external diameter and bottle internal diameter match and can slide in bottle, the bottle space carrying liquid raw material between the sliding plug and the pump housing.

Described emulsion vacuum pump, its feature also are to be provided with base at bottle body bottom, have the opening of equilibrium air pressure on the base.

Beneficial effect, owing to adopted technical scheme described in the utility model, when being positioned at the piston pump imbibition on emulsion vacuum pump top, 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 emulsion vacuum pump 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 a bottle interior material to evaporate in the atmosphere, guaranteed that the result of use of the interior material of bottle also can prolong the effective life of bottle interior material.

Description of drawings:

Accompanying drawing is the cut-away view of an embodiment of emulsion vacuum pump described in the utility model.

Drawing explanation: 1-cover of dust, 2-head, 3-spring, 4-piston, 5-locking closure, 6-principal post, the 7-pump housing, 8-water shutoff pad, 9-bottle, the sliding plug of 10-, 11-base, 12-opening.

The specific embodiment:

As seen, described emulsion vacuum pump comprises head 2, piston pump, bottle 9 from accompanying drawing; Wherein piston pump is made up of spring 3, piston 4, locking closure 5, principal post 6, the pump housing 7, water shutoff pad 8, and water shutoff pad 8 constitutes a check valve with the opening (not marking among the figure) of the pump housing 7 bottoms; In cylindrical bottle 9, be provided with the sliding plug 10 that an external diameter and bottle 9 internal diameters match, carrying liquid raw material in the bottle 9 of sliding 7 of the plug 10 and the pump housings; Be provided with base 11 in bottle 9 bottoms, have the opening 12 of equilibrium air pressure on the base 11.

Its principle of work is when being positioned at the piston pump imbibition on emulsion vacuum pump top, owing to produce negative pressure in the bottle 9, the sliding plug 10 that will be positioned at bottle 9 is simultaneously inhaled and is made sliding plug 10 upward movements to bottle 9, reduces the interior effective volume of bottle, balance the air pressure inside of bottle 9.

Claims

1, a kind of emulsion vacuum pump comprises head (2), piston pump, bottle (9); It is characterized in that in bottle (9), being provided with that an external diameter and bottle (9) internal diameter match and the cunning that can slide is filled in (10) bottle (9) in.

2, emulsion vacuum pump according to claim 1 is characterized in that being provided with base (11) in bottle (9) bottom, has the opening (12) of equilibrium air pressure on the base (11).
