[0006] A detachable straw, the straw comprises a straw body and a fixing connecting piece, the straw body is clamped by two straw units, and the fixing connecting piece is sleeved on the top of the straw body.

[0007] On the basis of the above technical scheme, the utility model can further adopt the following technical scheme:

[0008] The inner side of the straw unit of the straw body is provided with a clamping strip and a clamping groove, the clamping strip protrudes from the inner side wall of the straw unit, and the clamping groove is recessed in the inner side wall of the straw unit.

[0009] The clamping strip and the clamping groove are arranged in parallel.

[0010] The clamping strip and the clamping groove are further provided with a recessed flow guide groove therebetween.

[0011] The card strip is a circular arc convex strip, and the inner recess shape of the card slot is consistent with the shape of the card strip.

[0012] The top surface of the straw unit is a horizontal surface, and the bottom surface of the straw unit is a circular arc-shaped curved surface that is inclined from the outer side of the straw unit to the inner side of the straw unit, so that the bottom of the straw body is in an arch structure.

[0013] The outer side of the fixed connecting piece is provided with at least two annular convex ribs, and the two annular convex ribs are respectively arranged at the upper part and the lower part of the fixed connecting piece.

[0014] The fixed connecting piece is provided with a through hole penetrating through the top surface and the bottom surface of the fixed connecting piece.

[0015] Compared with the prior art, the beneficial effects achieved by the utility model are as follows:

[0016] The utility model discloses a two straw units are designed to be mutually clamped structure, cooperate the use of fixed connecting piece, make the straw not easy to scatter and install conveniently, and simultaneously, disassembly is convenient, very beneficial to the disassembly and cleaning. On the other hand, the design of the annular convex rib of the fixed connecting piece not only can conveniently assemble the straw to the straw nozzle of the water cup such as the vacuum cup, but also can prevent the problem that the fixed connecting piece is torn when the straw is disassembled.

DETAILED DESCRIPTION

[0023] The utility model provides a detachable straw is further explained in connection with the drawings.

[0024] Embodiment one, as shown in Figures 1-5 A detachable straw, the straw comprises a straw body 1 and a fixing connector 3, the straw body 1 is clamped by two straw units 2, and the fixing connector 3 is sleeved on the top of the straw body 1.

[0025] The fixing connector 3 is fixed on the straw body 1 by a gluing process, which can fix the straw body 1 from being scattered, facilitate the installation of the two straw units 2, and facilitate the assembly of the straw on the straw nozzle of the water cup.

[0026] Specifically, the inner side of the straw unit 2 of the straw body 1 is provided with a clamping strip 21 and a clamping groove 22, the clamping strip 21 protrudes from the inner side wall 23 of the straw unit 2, and the clamping groove 22 is concave in the inner side wall 23 of the straw unit 2.
