Telescopic suction pipe structure

Abstract

The invention relates to a telescopic suction pipe structure. The telescopic suction pipe structure comprises an upper cover, a clamshell cover, a hollow sealed cylinder, an air inlet, an air inlet valve and a suction pipe, wherein the clamshell cover is pivoted to the upper side of the upper cover, a sealing cover extending downward is arranged at the bottom of the clamshell cover, the hollow sealed cylinder vertically penetrates through the upper cover, the edge of the hollow sealed cylinder is higher than the plane where the upper cover is located, the air inlet runs through the upper cover, the air inlet valve is arranged at the bottom of the upper cover and communicated with the air inlet, the suction pipe comprises a suction nozzle part, a naturally-telescopic compression part and awater suction part which are sequentially connected from top to bottom, the suction pipe is fixed into the sealed cylinder, when the clamshell cover is closed, the clamshell cover presses the suctionpipe to be compressed downward and the sealing cover and an opening of the upper side of the sealed cylinder are buckled and sealed, and when the clamshell cover is opened, the suction pipe extends upward and the suction nozzle part is higher than the opening of the upper side of the sealed cylinder. The telescopic suction pipe structure is simple in structure and convenient to use, the suction nozzle part gently pops up after the clamshell cover is opened, the hot water spraying-out probability can be effectively avoided, and the spraying/leaking prevention effect is achieved.

Description

technical field [0001] The invention relates to a straw, in particular to a telescopic straw structure. Background technique [0002] For liquid containers such as kettles and feeding bottles in daily life, in order to facilitate drinking, straws are generally added to the mouth of the container. The following introduces the two common straw structure designs on the market: [0003] (1) Straw structure of clamshell container [0004] The flip of the flip-top container is generally provided with a downward-extending pressing piece. When the flip is closed, the pressing piece is driven to squeeze the straw nozzle downward, so that the straw is closed, thereby preventing the liquid from flowing out. [0005] The structure of the first type of straw seems simple, but because it is closed by the extrusion force of the pressing tablet, the upper cover is easily opened by the reaction force of the straw nozzle, so it is necessary to install a buckle structure on the upper cover to...

[0008] The second straw structure is the most widely used water sealing method on the market. Its advantages are simple structure and easy to use. The disadvantage is that when the slide is opened too quickly, the straw will spray water outwards, and there is a risk of burns.
