[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] See also Figures 1-4 The present invention provides a multifunctional life straw technical solution: it includes a tube body 1 with a filtering structure 11, a water suction pipe 2, and a water outlet pipe 3; it is used to connect the water suction pipe 2 to an external water source, suck the water outlet pipe 3, so that negative pressure is generated in the tube body 1, thereby drinking water from the drinking water source, wherein the filtering structure 11 is existing technology, and the corresponding filtering material can be directly purchased on the market, so it will not be described in detail in this specification.

[0023] Furthermore, the water outlet pipe 3 is telescopically mounted on the pipe body 1 by means of a nozzle piece 5; in one embodiment, the water outlet pipe 3 is pressed on the nozzle piece 5 by a movable structure, and the telescopic connection between the water outlet pipe 3 and the pipe body 1 is achieved by means of the movable structure; the water outlet pipe 3 needs to be inserted into the nozzle piece 5; and the movable structure includes a plurality of annular grooves 61 provided on the outer surface of the water outlet pipe 3 and a sealing ring 62 filled in the annular groove 61; the sealing ring 62 fits tightly against the inner wall of the nozzle piece 5; in this way, the friction between the sealing ring 62 and the inner wall of the nozzle piece 5 is utilized to fix the water outlet pipe 3 to a certain extent on the nozzle piece 5 after extension and contraction, and the nozzle piece 5 is sealed and connected to the pipe body 1, and the gap between the water outlet pipe 3 and the inner wall of the nozzle piece 5 will be filled by means of the sealing ring 62, thereby making the water outlet pipe 3 and the pipe body 1 sealed and connected, so that the user can smoothly suck water through the pipe body 1.

[0024] Furthermore, in order to stabilize the extension and retraction stroke of the water outlet pipe 3 in the pipe body 1, the movable structure is provided with a clamping ring 64 protruding outward on the outer surface of the water outlet pipe 3 and a clamping groove 63 provided on the inner wall of the nozzle piece 5; the clamping ring 64 is clamped into the clamping groove 63 to fix the water outlet pipe 3 and the nozzle piece 5; in one embodiment, there are two clamping rings 64 and two clamping grooves 63 respectively and they are distributed in upper and lower positions, so that when the water outlet pipe 3 is retracted, the clamping ring 64 in the same position corresponds to and is clamped into the clamping groove 63, and when the water outlet pipe 3 is extended, the clamping ring 64 located in the lower position will be clamped into the clamping groove 63 in the upper position.

[0025] Furthermore, the outlet pipe 3 is provided with a variable sealing portion 4; the variable sealing portion 4 moves along with the outlet pipe 3 in the nozzle piece 5 to switch the communication state between the outlet pipe 3 and the nozzle piece 5. Specifically, the outlet pipe 3 is retracted into the outlet pipe 3 so that the variable sealing portion 4 is located in the nozzle piece 5, forming a sealed communication state A between the outlet pipe 3 and the nozzle piece 5 (see FIG. Figure 2 ); the outlet pipe 3 extends out of the outlet pipe 3, the variable sealing portion 4 is located outside the nozzle member 5 to communicate with the outside world, constituting the outlet pipe 3 and the nozzle member 5 in an open communication state B (see Figure 3 Preferably, the variable sealing portion 4 is a semi-open notch cut out in the water outlet pipe 3, so that after the variable sealing portion 4 extends out, the sealing environment between the water outlet pipe 3 and the nozzle piece 5 will be destroyed, thereby making it difficult for the user to obtain water in the pipe body 1 by sucking the water outlet pipe 3.

[0026] Furthermore, to seal the water outlet pipe 3 when drinking is not required, the bottom sidewall of the water outlet pipe 3 has an opening 31 for communicating with the nozzle piece 5. In the open communication state B, the opening 31 corresponds to the inner wall of the nozzle piece 5, making it difficult for water to flow out through the opening 31. Furthermore, the clamping ring 64 can be disposed below the opening 31 in the clamping groove 63 to improve the sealing effect.

[0027] Preferably, the nozzle piece 5 is detachably connected to the tube body 1 via threads, so that the filter structure 11 in the tube body 1 can be replaced.

[0028] Furthermore, to enhance dustproofing and facilitate portability, a pipe cover 7 is hingedly connected to the nozzle 5. The pipe cover 7 covers the water outlet pipe 3 to achieve dustproofing. A handle 8 is provided on one side of the nozzle 5 to facilitate portability. The handle 8 limits the position of the pipe cover 7 after it is opened. In one embodiment, the pipe cover 7 has a tongue 71 on one side. The user can use the tongue 71 to open the pipe cover 7, and the tongue 71 can be snapped into the handle 8 to achieve a limiting effect, avoiding interference with user use.

[0029] Furthermore, in order to cope with the changing emergency situations outdoors, a binding belt 9 is provided on the bottom side of the tube body 1. If the user is injured outdoors and has wrapped a bandage around the wound, the binding belt 9 can be torn off to bind the wound and stop bleeding.

[0030] The water outlet pipe 3 mentioned in this patent is preferably made of food-grade plastic, which has a certain toughness and can expand and contract corresponding to the strain. The restraint belt 9 can be made of composite rubber and has good elasticity.

[0031] Working principle: The user opens the pipe cover 7 by lifting the tongue 71 and presses down the water outlet pipe 3, so that the variable sealing part 4 is located in the pipe mouth piece 5, and at the same time the opening 31 is separated from the inner wall of the pipe mouth piece 5, reaching the sealed communication state A, so that the water suction pipe 2, the tube body 1, and the water outlet pipe 3 are connected, so that drinking can be carried out; when drinking is finished, the user pulls out the water outlet pipe 3, so that the variable sealing part 4 is located outside the pipe mouth piece 5, and at the same time the opening 31 corresponds to the inner wall of the pipe mouth piece 5, reaching the open communication state B, so that the communication relationship between the tube body 1 and the water outlet pipe 3 is cut off.
