[0025] The backflow prevention component 3 can effectively prevent the liquid in the straw from flowing back and causing pollution by setting the backflow prevention component 3. The backflow prevention component 3 includes a hose 301, a blocking ring 302, a clamp 303, a through hole 304 and a closed hole 305. The main straw 1 is installed with the hose 301, and the other end of the hose 301 is installed on the first connecting straw 2. The blocking ring 302 is installed on the inner wall of the hose 301, and the clamp 303 is movably installed on the outer wall of the hose 301. The clamp 303 is provided with a through hole 304 and a closed hole 305, and the through hole 304 and the closed hole 305 are connected. When the straw needs to be pulled out, the hose 301 can be pushed into the closed hole 305, at which time the hose 301 can be squeezed and compressed, and the blocking ring 302 can also be squeezed and fitted together, which can improve the sealing performance of the straw blocking, and the upper and lower sections of the straw can be divided and blocked, so that when the straw is pulled out, the liquid in the straw can be effectively prevented from flowing back and causing pollution.
[0026] Further, see Figure 2 A limiting ring 306 is installed on the outer wall of the hose 301. There are two limiting rings 306. The two limiting rings 306 are respectively distributed on the upper and lower sides of the clamp 303. Through the setting of the two limiting rings 306, the movement of the clamp 303 can be restricted to prevent the clamp 303 from falling off from the through hole 304.
[0027] Further, see Figure 2 The blocking ring 302 is made of natural rubber material. Natural rubber meets the use requirements of the blocking ring 302, and the rubber has good sealing performance. When squeezed, it can effectively form a blockage to prevent the liquid in the straw from flowing back.
[0028] Further, see Figure 1 A plurality of contact strips 5 are installed on the outer wall of the main straw 1, and the plurality of contact strips 5 are equidistantly distributed on the outer wall of the main straw 1 in a circumferential manner. The arrangement of the contact strips 5 can enhance the friction force when holding the straw, which is beneficial to the insertion and removal of the straw.
[0029] Embodiment 2:
[0030] like Figure 1 , Figure 3 As shown, on the basis of Example 1, by providing the spoon-shaped component 4, the straw can have the effect of digging solid food, thereby improving the practicality of the straw.

The insert tube 401 is installed on the main straw 1, and the mounting tube 402 is detachably installed on the insert tube 401. The digging spoon 403 is installed on the mounting tube 402. When it is necessary to dig solid food, the mounting tube 402 can be installed on the insert tube 401. At this time, the mounting tube 402 can be rotated into the insert tube 401, and the external thread 404 and the internal thread 405 are adapted to each other. The digging spoon 403 can be installed on the straw. By setting the reinforcement shell 406, the strength of the digging spoon 403 can be increased, and the convenience of the digging spoon 403 when digging food is improved.
[0032] Further, see Figure 3 The outer wall of the insert tube 401 is provided with an external thread 404, and the inner wall of the mounting tube 402 is provided with an internal thread 405, the external thread 404 is adapted to the internal thread 405, the external thread 404 is adapted to the internal thread 405, and the mounting tube 402 is rotated into the insert tube 401, and the scoop 403 can be installed on the straw through the mutual cooperation of the internal thread 405 and the external thread 404.
[0033] Further, see Figure 3 A reinforcement shell 406 is installed in the digging spoon 403, and the thickness of the reinforcement shell 406 ranges from one millimeter to two millimeters. By setting the reinforcement shell 406, the strength of the digging spoon 403 can be increased, and the convenience of the digging spoon 403 when digging food is improved. The thickness range of 406 effectively improves the strength of 403 without causing waste of materials.
[0034] Further, see Figure 4 The outer wall of the main straw 1 is provided with an outer waterproof coating 6, and the inner wall of the main straw 1 is provided with an inner waterproof coating 7. By providing the outer waterproof coating 6 and the inner waterproof coating 7, the waterproof property of the inner and outer sides of the straw can be improved, and the shedding of substances on the straw caused by long-term soaking of the straw can be effectively reduced.
[0035] Working principle of the utility model: when the straw needs to be pulled out, the hose 301 can be pushed into the closed hole 305, at which time the hose 301 can be squeezed and compressed, and the blocking ring 302 can also be squeezed and fitted together, which can improve the sealing performance of the straw blocking, and the upper and lower ends of the straw can be divided and blocked, which can effectively prevent the liquid in the straw from flowing back and causing pollution when the straw is pulled out. When solid food needs to be eaten, the installation tube 402 can be installed on the insertion tube 401, and at this time, the insertion tube 401 can be rotated to the inside. The movable mounting tube 402, the outer thread 404 and the inner thread 405 are adapted to each other, and the digging spoon 403 can be mounted on the straw. By setting the reinforcing shell 406, the strength of the digging spoon 403 can be increased, and the convenience of the digging spoon 403 when digging food is improved. By setting the contact strip 5, the friction force when holding the straw can be improved, which is beneficial for the insertion and removal of the straw.
