Abstract
The utility model discloses a capillary liquid blowing pipe, which comprises a rubber pipe and a suction pipe, wherein a cavity is formed in the rubber pipe, a liquid inlet communicated with the cavity is formed in the rubber pipe, a sleeve is communicated with the liquid inlet, the suction pipe is inserted into the sleeve, and a gap is reserved between the suction pipe and the sleeve. According to the capillary liquid blowing pipe, through the arrangement of the square sleeve, after the round suction pipe is inserted into the square sleeve, gaps are formed between the four corners of the square sleeve and the round suction pipe, so that after the rubber pipe absorbs liquid, the rubber pipe is inverted and fixed, and gas is discharged from the gaps, and the pressure intensity inside and outside the rubber pipe can be consistent.
Description
Technical Field
The utility model relates to the field of experimental tools, in particular to a capillary liquid blowing pipe.
Background
The capillary liquid blowing pipe is a pipe for extracting liquid and blowing out, the old liquid blowing pipe is provided with holes on the rubber pipe for exhausting, the mode easily causes inconsistent internal and external pressure, the sample suction amount does not reach the standard, and the extracting liquid easily flows out from the holes of the base.
Disclosure of Invention
The utility model provides a capillary liquid blowing pipe, which comprises a rubber pipe and a suction pipe, wherein a cavity is formed in the rubber pipe, a liquid inlet communicated with the cavity is formed in the rubber pipe, a sleeve is communicated with the liquid inlet, the suction pipe is inserted into the sleeve, and a gap is reserved between the suction pipe and the sleeve.
Preferably, the suction pipe is a circular suction pipe, and the sleeve is inserted into the circular suction pipe.
Preferably, the sleeve is a square sleeve, the circular suction pipe is inserted into the square sleeve, and gaps communicated with the cavity are reserved at four corners between the circular suction pipe and the square sleeve.
Compared with the prior art, the utility model has the following beneficial effects:
(1) Through square sheathed tube setting, after square sheathed tube is inserted to the circular straw, produce the gap between square sheathed tube four corners and the circular straw, after being convenient for the rubber tube to absorb liquid, invert the rubber tube fixedly to make gaseous discharge in the gap, can reach the inside and outside pressure of rubber tube unanimously.
Drawings
FIG. 1 is a schematic diagram of the overall structure of the present utility model;
fig. 2 is a front view of the present utility model.
Detailed Description
The utility model is further described in connection with the following detailed description, in order to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the utility model easy to understand.
As shown in figures 1-2, the capillary liquid blowing pipe comprises a rubber pipe 1 and a suction pipe, wherein a cavity is formed in the rubber pipe 1, a liquid inlet communicated with the cavity is formed in the rubber pipe 1, a sleeve is communicated with the liquid inlet, the suction pipe is inserted into the sleeve, and a gap is reserved between the suction pipe and the sleeve.
In the specific embodiment, the suction pipe is a circular suction pipe 2, and the sleeve is inserted into the circular suction pipe 2; the sleeve is a square sleeve 3, the circular suction pipe 2 is inserted into the square sleeve 3, and gaps communicated with the cavity are reserved at four corners between the circular suction pipe 2 and the square sleeve 3.
The working principle and the use flow of the utility model are as follows: when the capillary liquid blowing pipe is used, the circular suction pipe 2 is inserted into the square sleeve 3, then the circular suction pipe 2 is placed into liquid, the column rubber suction pipe 1 is pinched again to loosen hands, so that the liquid is sucked into the rubber suction pipe 1 from the circular suction pipe 2, then the rubber suction pipe 1 is inverted, the liquid enters the bottom of the rubber suction pipe 1, and the cavity rises to be discharged from a gap, so that the internal pressure and the external pressure are consistent.
The foregoing has shown and described the basic principles and main features of the present utility model and the advantages of the present utility model. It will be understood by those skilled in the art that the present utility model is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present utility model, and various changes and modifications may be made without departing from the spirit and scope of the utility model, which is defined in the appended claims. The scope of the utility model is defined by the appended claims and equivalents thereof.
