Description

Straw structure

Technical field

The invention relates to a straw, and particularly refers to a straw structure that can be conveniently used, cleaned, and has the environmental protection function of repeated use.

Background technique

A commonly used environmental protection straw is shown in Figure 6, which is a ring-shaped body 9 with a gap 91 formed to form two pairs of mating ends 92. The mating ends 92 are provided with fasteners 93. However, in order to allow the mating ends 92 to be buckled with each other The thickness of the main body 9 is significantly larger than other parts by the provision of the buckle 93, which makes the main body 9 too large and heavy; in addition, one side of the commonly used environmental protection straw is an annular section 94. When the main body 9 is opened, the annular section 94 will produce corresponding deformation, but in order to prevent excessive bending and deformation of the ring section 94, the opening of the body 9 must not be too large, but this will cause difficulties in cleaning; however, if the design thickness of the ring section 94 is reduced, and Form a connecting sheet, which may increase the opening range of the body 9, but this will further aggravate the problem of uneven thickness of each section of the body 9, and the decrease in the thickness of the ring section 94 will reduce the structural strength, and the body 9 will be repeatedly stretched and closed. , The damage speed of the ring section 94 due to elastic fatigue will increase: In addition, the configuration of the fastening member 93 on the mating end 92 will make it difficult for the mating ends 92 to separate from each other, and the opening range of the body 9 Limited, causing difficulties in cleaning.

Another commonly used environmental protection straw is shown in Figure 7. It also has a ring-shaped body 10 with a gap 101 formed to form two pairs of mating ends 102. The mating ends 102 are provided with overlapping fasteners 103, so the The thickness of the mating end 102 is also significantly larger than other parts, and the shape of the central channel of the main body 10 is non-circular, which makes it easy for solid particles to pass through the central channel not smoothly, or knock the inner wall of the main body 10, or even get stuck; In addition, the structural type of the fastener 103 also makes it difficult for the mating ends 102 to open mutually, which causes troubles in cleaning.

In order to reduce the thickness of the mating end, another commonly used environmental protection straw is shown in FIG. 8. The design of the fastening end 112 must be simpler to reduce the volume. Therefore, the fastening ability of the fastening end 112 is obviously insufficient. , If the straw is slightly stressed, the buckling ends 112 will disengage from each other; in addition, because the design of the buckling ends 112 is miniaturized, the gap cannot be effectively shielded, and the air will easily enter the central channel through the gap, which will cause The suction power is reduced and even leakage occurs.

In view of this, how to improve the above-mentioned problem is the primary problem to be solved by the present invention.
