Abstract

The utility model discloses a straw, which comprises a straw body, wherein the straw body comprises an upper straw and a lower straw, a valve cavity is arranged on the bottom portion of the upper straw, the upper portion of the lower straw and the valve cavity are inserted and matched, a shrinkage pool with a circular conical surface is arranged on the top end of the lower straw, the inner diameter of the shrinkage pool is bigger than the inner diameter of the lower straw, and a one-way valve is arranged in the valve cavity. Because the one-way valve is arranged in the straw, the one-way valve can be opened just when beverage in a package box is suckled, and the beverage can be sucked out. When stopping suckling, the one-way valve returns to be closed, and the beverage in a pipe is affected by negative pressure not to overflow from a pipe mouth.

Description

Suction pipe

Technical field

The utility model relates to a kind of device of drawing beverage.

Background technology

Suction pipe is easy to use with it, and the edible packaging group beverage of the packaged beverage of feature extensive adapted, particularly children, child that price is cheap obtains using more widely.Traditional suction pipe is straight pipe, along with updating, has occurred the bent suction pipe of movable telescopic pipe and top, but its basic structure do not change, in essence or straight pipe structure.When the structure of straight pipe easily causes and draws beverage and suspend, beverage relies on coherence from the excessive phenomenon of the mouth of pipe, while not only causing waste also to produce pollution, particularly children and child to use, is difficult for holding, and the clothing of often making dirty, brings many unnecessary troubles to the head of a family.

Summary of the invention

The purpose of this utility model is to provide a kind of excessive suction pipe that is difficult for while drawing beverage.

The technical solution of the utility model is: comprise suction pipe body, described suction pipe body is made up of upper suction pipe and lower suction pipe, the bottom of described upper suction pipe is provided with valve pocket, peg graft and coordinate with valve pocket in the top of lower suction pipe, the top of lower suction pipe is provided with the shrinkage pool with taper seat, shrinkage pool internal diameter is greater than the internal diameter of lower suction pipe, and check valve is housed in valve pocket.

Described check valve comprises ball and spring, and the diameter of described ball is less than the internal diameter of lower suction pipe top shrinkage pool, but is greater than the internal diameter of lower suction pipe, and spring is positioned at ball top, and spring diameter is greater than the internal diameter of suction pipe.

Between spring top and valve pocket, be also provided with every bamboo or wicker fence.

Owing to being provided with check valve in the utility model, the beverage in packing box can only just be opened by check valve in the time sucking, the sucking-off of beverage ability; While stopping sucking, check valve reset close, pipe in beverage be subject to negative pressure affect be difficult for overflow from the mouth of pipe.

Detailed description of the invention

Below in conjunction with drawings and Examples, the utility model is described in further detail, but does not form any restriction of the present utility model.Shown in Fig. 1 and Fig. 2, the utility model comprises suction pipe body, described suction pipe body is made up of upper suction pipe 1 and lower suction pipe 2, the bottom of described upper suction pipe 1 is provided with valve pocket 3, the top of lower suction pipe 2 and valve pocket 3 are plugged to one, the top of lower suction pipe 2 is provided with the shrinkage pool 4 with taper seat, and shrinkage pool 4 internal diameters are greater than the internal diameter of lower suction pipe 2, in valve pocket 3, check valve are housed.Described check valve comprises ball 7 and spring 6, and the diameter of described ball 7 is less than the internal diameter of lower suction pipe 2 top shrinkage pools 4, but is greater than the internal diameter of lower suction pipe 2, and spring 6 is positioned at ball 7 tops, and spring 6 diameters are greater than the internal diameter of suction pipe 1.For preventing in foreign material suction inlet, between spring 6 tops and valve pocket 3, be also provided with every bamboo or wicker fence 5.

When use, lower suction pipe 2 is inserted in packing box, there is negative pressure in the aspiration port of upper pipe, ball 7 in check valve moves to suction inlet direction, and Compress Spring 6, and ball 7 leaves the shrinkage pool 4 on lower suction pipe 2 tops, between produce gap, now, upper suction pipe 1 and lower suction pipe 2 all connect, and beverage is sucked out by this gap.In the time stopping sucking, overpressure tends to be balanced, and spring 6 resets, force ball 7 to be close to the shrinkage pool 4 on suction pipe 1 top, block lower suction pipe 2, cause suction pipe 1 and lower suction pipe 2 not to connect, beverage can not flow in box, meanwhile, and the effect resetting due to spring 6, make the interior generation negative pressure of suction pipe 1, because upper suction pipe 1 lower end by shutoff, forces the beverage retraction in suction pipe 1 upper pipes, with balance pipe internal pressure, like this, the beverage at upper suction pipe 1 suction inlet place, upper end sucks back in pipe, is difficult for outside effuser.
