Abstract

The utility model provides a side hole fluid aspirator which includes a pipette and an aspirating ball. The aspirating ball is in sealed and permanent connection with the upper end of the pipette, the lower end of the pipette is a close structure, at least one side wall of the pipette is a direct pipe wall, and a lateral fluid aspirating opening is arranged on the lower end of the direct pipe wall on one side. In the utility model, a lateral fluid aspirating opening is arranged on the direct pipe wall on the lower end of the pipette, thus solving the problem that the pipette cannot suck residual fluid because the length of the pipette is shorter than the depth of the container holding the fluid. Moreover, the utility model has the advantages of very simple structure, no extra added materials, and very convenient manufacture, thereby providing great advantages for the production and use of bottled fluid assembled with fluid aspirators.

Description

The side opening aspirator

Technical field

The utility model relates to a kind of aspirator, especially a kind of side opening aspirator.

Background technology

Aspirator is a kind of liquid sucking device that comprises a pipette and a Liquid absorption ball, and the Liquid absorption ball sealing connects firmly the upper end in pipette.Aspirator of the prior art, its liquid sucting port all are arranged on the lower end of pipette usually, and orifice plane is towards the below.Such aspirator is by placing liquid with pipette, and the liquid sucting port down of pipette lower end sucks pipette with liquid.Liquid is remaining not for a long time in bottle, and bottle is tilted, and in the oblique corner at the bottom of remaining liq is gathered bottle, the lower end of pipette is reached the bottommost in this corner, can be with liquid exhaustion in the bottle.Therefore, existing aspirator, wherein the length of pipette must be greater than the height of described liquid holding bottle.Such applicable cases is arranged in the practical application, in the liquid holding bottle packing box, will attach aspirator.If use existing aspirator, then aspirator will exceed liquid holding bottle.Like this, the packing inconvenience of bottle also can be wasted packaging material and be increased packaging volume.

A kind of aspirator is arranged in the prior art, and the lower end of the pipette on it is provided with a bend loss, establishes liquid sucting port in the termination of bend loss, and this liquid sucting port is positioned at the side of pipette main body pipe, and the liquid holding bottle height that the pipette length of this aspirator can match well usefulness is little.But, this pipette with bend loss, bend loss must be the width that will exceed straight tube, it is subjected to the restriction of the bottleneck diameter of liquid holding bottle.And this aspirator complex structure, make loaded down with trivial details.

The utility model content

The purpose of this utility model is to improve the deficiencies in the prior art, provides a kind of pipette length wherein but liquid in container can be exhausted less than the degree of depth of the liquid container of institute's adapted, and side opening aspirator simple in structure, easy to make.

The purpose of this utility model is achieved in that

The side opening aspirator that the utility model provides comprises a pipette and a Liquid absorption ball, the sealing of described Liquid absorption ball connect firmly upper end in described pipette, the lower end of described pipette is an enclosed construction, the pipe sidewall of its at least one side is straight shape tube wall, is provided with the side direction liquid sucting port in the lower end of this straight shape tube wall of a side.

Further, on the described pipette, the tube wall relative with described side direction liquid sucting port is preferably the arc tube wall to this side direction liquid sucting port inclination.

The side opening aspirator that the utility model provides, by on the straight shape sidewall in pipette lower end, establishing the side direction liquid sucting port, solve pipette and be shorter in length than the liquid container degree of depth and the problem of the raffinate that can not exhaust, and the structure of this pipette is very simple, the not extra material that increases, make also very conveniently, be the production of the bottling liquid product that sets aspirator and the use condition that provides great convenience.

Description of drawings

The utility model is described in further detail below in conjunction with accompanying drawing.

The structural representation of the side opening aspirator that Fig. 1 provides for the utility model;

Fig. 2 is the structural representation of pipette in the side opening aspirator shown in Figure 1;

The side opening aspirator that Fig. 3 provides for use the utility model is inhaled the schematic diagram of raffinate in the liquid container.

The specific embodiment

As shown in Figure 1, the side opening aspirator that the utility model provides comprises a pipette 1 and a Liquid absorption ball 2, Liquid absorption ball 2 comprises the elastic ball made by the rubber elastomeric material and is used for elastic ball and pipette linked together and makes the attaching parts that the liquid container of this aspirator and adapted connects firmly, Liquid absorption ball 2 sealing connect firmly upper end in pipette 1, the lower end 11 of pipette 1 is an enclosed construction, the pipe sidewall 12 of its at least one side is straight shape tube wall, is provided with a side direction liquid sucting port 13 in the lower end of this straight shape tube wall of a side.

Described straight shape tube wall can be the straight tube wall that is parallel to pipette axis 0, also can be not parallel with the pipette axis straight tube wall, for example is the straight tube wall that becomes the inclination of certain taper from top to bottom.

Further, suck for convenience and do not retain raffinate in liquid and the pipette, on the pipette 1, the tube wall 14 relative with side direction liquid sucting port 13 is the arc tube wall that tilts to this side direction liquid sucting port 13.

As shown in Figure 3, when the side opening aspirator that uses the utility model to provide is inhaled in the bottle raffinate, bottle 3 is tilted, make raffinate 4 place on the sidewall 31 on bottle top, then the liquid sucting port 13 on the 1 lower end sidewall of pipette on this side opening aspirator is attached on the bottle side-wall, moving (moving direction is seen shown in the arrow among Fig. 3) along bottle side-wall can exhaust raffinate, and needn't be as existing aspirator, and the corner at the bottom of raffinate in the bottle is gathered bottle can exhaust.

Claims (2)

1. side opening aspirator, it is characterized in that: comprise a pipette and a Liquid absorption ball, the sealing of described Liquid absorption ball connect firmly upper end in described pipette, the lower end of described pipette is an enclosed construction, the pipe sidewall of its at least one side is straight shape tube wall, is provided with the side direction liquid sucting port in the lower end of the straight shape tube wall of a side.

2. side opening aspirator according to claim 1 is characterized in that: on the described pipette, the tube wall relative with described side direction liquid sucting port is the arc tube wall that tilts to this side direction liquid sucting port direction.
