Abstract
The invention discloses a backflow preventive beverage straw which comprises a suction nozzle, a flexible valve and a guide tube. The suction nozzle comprises an upper portion, a middle portion and a lower portion, a support is arranged inside the middle portion of the suction nozzle, the flexible valve is movably connected onto the support, and the lower portion of the suction nozzle is closely connected with the guide tube. The backflow preventive beverage straw has the advantages that the flexible valve can be upwardly stretched to deform under the effect of suction force, and beverage can flow through a passage of the support to continuously upwardly move; external air can be partitioned by the beverage on a section above the flexible valve after the suction force disappears, the beverage on the section above the flexible valve and beverage in the guide tube can downwardly move under the effect of the gravity, the flexible valve can be driven to downwardly move, the passage of the support can be closed, and accordingly backflow of the beverage can be prevented; the flexible valve inside the backflow preventive beverage straw only can be upwardly opened, accordingly, the beverage can be assuredly sucked into the mouth of a drinker, backflow of the beverage can be effectively prevented, and contamination on remaining beverage can be reduced.
Description
Technical field
The present invention relates to the straw of a kind of straw, especially anti-backflow.
Background technology
Common straw is about one blank pipe directly communicated, and during the release of suction, a part of beverage can be flowed back in carafe by suction pipe from mouth under gravity again, pollutes original cleaning beverage in bottle；If disposably cannot not drinking completely, having a strong impact on second time and drinking.
Summary of the invention
It is an object of the invention to the weak point overcoming prior art to exist, and the straw of a kind of anti-backflow is provided.
For achieving the above object, the technical solution of the present invention is: the straw of a kind of anti-backflow is made up of suction nozzle, soft valve and conduit, and suction nozzle is made up of top, middle part, bottom, and the inside at middle part includes support, soft valve is movably connected on support, the bottom compact siro spinning technology conduit of suction nozzle.Soft valve is upwards stretched deformation under the effect of suction, and beverage constantly moves up through the path of support；Suction disappears, and one section of beverage above soft valve is separated by the air in the external world, and one section of beverage above soft valve adds the beverage in upper conduit, moves down under gravity, drives soft valve to move down, close the path of support, prevent the refluence of beverage.
The invention has the beneficial effects as follows: be provided with soft valve inside the straw of a kind of anti-backflow, can only upwardly open, it is ensured that in beverage suction inlet, effectively prevent the refluence of beverage, decrease the pollution to remaining beverage.
The present invention is further described with embodiment below in conjunction with the accompanying drawings.

Fig. 2 suction nozzle axonometric chart.
Fig. 3 suction nozzle rip cutting figure.
Fig. 4 soft valve axonometric chart.
Fig. 5 crosses the sectional view of AA.
As shown in Figure 1 to Figure 3, wherein: 1 top, 2 conduits, 3 soft valves, 4 supports, 5 bottoms, in the middle part of 6.
Detailed description of the invention
As shown in Figure 1 to Figure 3, the present invention is made up of suction nozzle, soft valve 3 and conduit 2, and suction nozzle is made up of top 1, middle part 6, bottom 5, and the inside at middle part 6 includes support 4, and soft valve 3 is movably connected on support 4, the bottom 5 compact siro spinning technology conduit 2 of suction nozzle.
The above, only present pre-ferred embodiments, therefore the scope that the present invention implements, the equivalence change i.e. made and modification can not be limited according to scope of the present invention patent and description with this, all should still remain within the scope of the patent.
