Composite anti-blocking suction pipe

Abstract

The invention discloses a composite anti-blocking suction pipe. The composite anti-blocking suction pipe comprises a main pipe (1) and an assistant pipe (2) which are bonded together side by side, wherein a plurality of vent holes (3) are formed in the pipe wall of the assistant pipe along the axis of the assistant pipe; the main pipe is longer than the assistant pipe; the top end of the main pipe is higher than that of the assistant pipe; bevel cuts are respectively formed in the bottom ends of the main pipe and the assistant pipe; the plurality of vent holes are formed at equal intervals and distributed in the pipe wall of the assistant pipe in the axial direction of the assistant pipe; the vent holes are divided into two groups, and the two groups of vent holes are symmetrically formed through the axis of the assistant pipe. Therefore, when the main pipe and the assistant pipe are bonded, the two groups of vent holes can be enabled not to be blocked; the internal diameter of the assistant pipe is smaller than or equal to that of the main pipe, so that more materials are saved. The composite anti-blocking suction pipe has the benefits that the structure is skilful, the implementation is easy, and the smooth liquid suction can be effectively guaranteed.

Description

technical field [0001] The invention relates to a composite anti-blocking suction pipe. Background technique [0002] Existing straws are all single straws. When consumers taste boxed beverages, they first puncture the sealing layer on the top surface of the beverage with the short of straw to form a suction hole, and then extend the straw into the suction hole to absorb the beverage. [0003] Because the suction hole and the straw are often in close contact, the inside and outside of the box are not connected at the suction hole. Therefore, in the process of absorbing the beverage, as the liquid in the box decreases, the air pressure in the box decreases, forming a gap with the outside. Due to the pressure difference, it is difficult for consumers to suck up the liquid in the clean box, or it is very laborious to suck up the liquid. Therefore, it is necessary to design a new type of anti-blocking straw. Contents of the invention [0004] The technical problem to be solve...
