Abstract

The utility model relates to a vacuum self suction emulsion bottle, which solves the problem in modern daily chemical containers that as the inner part of the container must be communicated with atmosphere, so that the substance in the container is volatile to affect the application effect of the substance in the container. The utility model is composed of a knob, a king post, a sub post and a bottle, which is characterized in that: with the function of the vacuum pump on the bottle, a piston which is capable of sliding inside the bottle and has an external diameter matched with the inner diameter of bottle is arranged inside the bottle, a liquid material is contained in the space between the piston and the bottle; the principle is that during the process of the vacuum pump gradually pumping the emulsion out of the bottle, the air pressure inside and outside pressures is balanced for the effective volume in the bottle decreased by the piston movement.

Description

Vacuum self-priming lotion pump

Technical field:

The utility model relates to a kind of container, particularly a kind of vacuum self-priming lotion 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 (as shown in Figure 4) of a band suction pipe at an upper portion thereof and stretch in the container suction pipe 10 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 vacuum self-priming 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 vacuum self-priming lotion pump, comprises head, principal post, subpost, bottle; It is characterized in that on the bottle upper surface of the bottleneck periphery of bottle, being provided with the circular orientation wing, on the bottle upper surface of the periphery of this circular orientation wing, be provided with the tubulose guide holder; Be provided with a barrel-shaped ripple plastic cement spring in the tubulose guide holder, the internal diameter of the circular orientation wing on this plastic spring lower end external diameter and the bottle matches, the bottom of plastic spring is provided with the inner concave that concaves, the area of this inner concave is located to have through hole the inner chamber of plastic spring is communicated with bottle intracavity greater than the bottleneck area on the bottle beyond the bottleneck of inner concave corresponding to bottle; Cover one subpost, overcoat one principal post in the upper shed of plastic spring, subpost central authorities have through hole and communicate with the inner chamber of plastic spring, the through hole that principal post central authorities are provided with the central authorities of siphunculus and described subpost matches, the siphunculus top of principal post central authorities radially has interconnection, and the siphunculus top of principal post central authorities is provided with check valve upwards; Principal post is with head outward, and the interconnection place of corresponding principal post has outlet on the joint, and the head bottom is placed in the tubulose guide holder of bottle and can slides in the tubulose guide holder; In bottle, be provided with the piston that an external diameter and bottle internal diameter match and can slide in bottle, the bottle space carrying liquid raw material between piston and bottle.

Described vacuum self-priming lotion pump is characterized in that being provided with bottom at bottle body bottom, has the pore of equilibrium air pressure on the bottom.

Described vacuum self-priming lotion pump is characterized in that stretching out a guide pipe at the bottleneck of bottle to plastic spring one side, and plastic spring stretches out a guide ring to bottleneck one side, and the internal diameter of guide ring is greater than the external diameter of described guide pipe.

Beneficial effect, owing to adopted technical scheme described in the utility model, when liquid is discharged by the head outlet in the head of pushing vacuum self-priming lotion pump repeatedly makes bottle, owing to produce negative pressure in the bottle, so the piston that will be positioned at bottle is simultaneously inhaled and is made the piston upward movement till bottle liquid is sucked to bottle, bottle inside that is to say that vacuum self-priming lotion pump described in the utility model is effective volume reaches equilibrium air pressure in the decreased locomotion bottle with piston effect, 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.
