[0022] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.

[0023] like Figs. 1-4 As shown, a dustproof travel mug includes a mug body 1 and a mug stopper 2 disposed at the top opening of the mug body 1;

[0024] The cup body 1 includes an outer cylinder 11 and an inner liner 12 concentrically fixed in the outer cylinder 11;

[0025] The cup stopper 2 includes a detachable water outlet seat 22 fixed inside the top opening of the inner liner 12, a diverter cylinder 24 concentrically fixed inside the water outlet seat 22, a sealing cover 23 movably disposed at the bottom opening of the water outlet seat 22, and a switch 25 disposed inside the diverter cylinder 24 and connected to the sealing cover 23. The switch 25 can drive the sealing cover 23 to move up and down to realize the function of closing and opening the bottom opening of the water outlet seat 22. The above structure and principle are all existing technologies.

[0026] The feature of this utility model is that an annular water outlet cavity 21 is formed between the outer peripheral surface of the diverter cylinder 24 and the inner peripheral surface of the water outlet seat 22, and the bottom outer wall of the diverter cylinder 24 and the bottom inner wall of the water outlet seat 22 are spaced at a certain distance so that the water flow can enter the interior of the annular water outlet cavity 21 when the bottom opening of the water outlet seat 22 is opened.

[0027] It also includes a dustproof component 3 on the cup stopper 2. The dustproof component 3 includes an inverted and detachable cup body 31 inserted and fixed in the annular water outlet cavity 21, a retaining ring 33 fitted on the outer circumferential surface of the diverter cylinder 24 and cooperating with the inner circumferential surface of the cup body 31, and a cup spout 32 detachably fixed to the outside of the top opening of the outer cylinder 11 and cooperating with the outer circumferential surface of the cup body 31.

[0028] The outer circumferential surface of the cup body 31 cooperates with the inner circumferential surface of the water outlet seat 22 and the inner circumferential surface of the cup nozzle 32, and the inner circumferential surface of the cup body 31 cooperates with the outer circumferential surface of the flow distribution cylinder 24;

[0029] A convex ring 331 is formed on the outer circumferential surface of the clamping ring 33, and a ring-shaped recess 312 is formed on the inner circumferential surface of the cup body 31, and the convex ring 331 is detachably embedded in the ring-shaped recess 312;

[0030] A ring-shaped notch 311 is formed on the outer circumferential surface of the opening of the cup body 31, the bottom surface of the ring-shaped notch 311 is located above the ring-shaped recess 312, and the inner wall of the ring-shaped notch 311 is spaced apart from the inner circumferential surface of the water outlet seat 22 to provide a space for the opening of the cup body 31 to expand outward.

[0031] A ring-shaped baffle 313 is formed on the outer circumferential surface of the cup body 31, the ring-shaped baffle 313 is located above the end opening of the cup nozzle 32, and the outer side edge of the ring-shaped baffle 313 is downwardly formed with a sleeve 314 which concentrically surrounds the outside of the end opening of the cup nozzle 32.

[0032] A ring-shaped cavity 321 is formed on the outer circumferential surface of the end opening of the cup nozzle 32, and a convex ring 315 is formed on the inner circumferential surface of the sleeve 314 towards the cup nozzle 32, and the end of the convex ring 315 is attached to the inner wall of the ring-shaped cavity 321.

[0033] The cross-sectional shape of the ring-shaped cavity 321 is arc-shaped.

[0034] The end opening of the sleeve 314 is downwardly formed with a flange 316 which is arranged in a ring shape, and the inner wall of the flange 316 is attached to the outer wall of the cup nozzle 32.

[0035] The bottom of the water outlet seat 22 is further fixed with a screen cylinder 26 which surrounds the outside of the sealing cover 23.

[0036] Method for use:

[0037] The cup body 31 is held by hand and pulled upward, and since the convex ring 331 is embedded in the ring-shaped recess 312 at this time, when the cup body 31 is moved upward, the convex ring 331 will force the opening of the cup body 31 to expand outward by the elastic force of the material itself in order to leave the ring-shaped recess 312, until the convex ring 331 leaves the ring-shaped recess 312 and is located above the ring-shaped recess 312, and the inner wall of the ring-shaped notch 311 is spaced apart from the inner circumferential surface of the water outlet seat 22 to provide a space for the opening of the cup body 31 to expand outward.

[0038] In the above process, the cup 31 will move the sleeve 314 on the ring 315 to move synchronously, because the end of the ring 315 is attached to the inner wall of the annular recess 321, so that the ring 315 will expand the opening of the sleeve 314 outwardly by the elastic force of its own material when it passes the edge of the inner wall of the annular recess 321, until the end of the ring 315 passes the edge of the inner wall of the annular recess 321 and is above the cup nozzle 32; when the opening of the cup 31 comes out of the annular water outlet chamber 21, the cup 31 is removed.

[0039] Then, after removing the cup nozzle 32, the cup plug 2 can be taken out together with the sieve cylinder 26, and then water can be poured into the inner container 12, and then the cup plug 2 is assembled together with the sieve cylinder 26 in the same way and the cup nozzle 32 is reassembled.

[0040] Pressing the switch 25 can drive the sealing cover 23 to move downward to open the bottom opening of the water outlet seat 22, then the cup 31 is placed flat with its opening upward, and the cup body 1 is gradually tilted so that the water in the inner container 12 enters the annular water outlet chamber 21 through the bottom opening of the water outlet seat 22. The structure and principle are all prior art.

[0041] Finally, the end opening of the cup nozzle 32 is moved above the opening of the cup 31, and the water in the annular water outlet chamber 21 will be poured out through the cup nozzle 32 into the cup 31, and the user can use it by holding the cup 31 with his hand; after use, press the switch 25 again to drive the sealing cover 23 to move upward, thereby closing the bottom opening of the water outlet seat 22.

[0042] After drinking the water, the water in the cup 31 is emptied, and then it is inverted and inserted into the annular water outlet chamber 21, and then the cup 31 is pressed slightly, and then the opening of the cup 31 is expanded outwardly according to the same principle, until the protruding ring 331 is embedded in the annular groove 312; in this process, the sleeve 314 on the cup 31 is sleeved outside the end opening of the cup nozzle 32, and the end opening of the sleeve 314 is also expanded outwardly while the cup 31 is pressed, until the end of the ring 315 quickly passes the edge of the inner wall of the annular recess 321 and is attached to the inner wall of the annular recess 321, and the inner wall of the flange 316 is attached to the outer wall of the cup nozzle 32.

[0043] When carrying out, since the inner wall of the turn-up 316 is also just fitted on the outer wall of the cup spout 32, the external dust is more difficult to enter the inside of the sleeve 314, thus forming the first barrier; meanwhile, since the end of the convex ring 315 is fitted on the inner wall of the annular concave cavity 321, even if a little dust enters the inside of the sleeve 314, it is more difficult to enter the inside of the end opening of the cup spout 32, thus forming the second barrier, when pouring water, the outflowing water will not bring dust into the cup body 31, thus realizing the remarkable dustproof function.

[0044] The utility model can establish two effective dustproof barriers between the cup body 31 and the cup spout 32 by the mutual cooperation of the turn-up 316 and the outer wall of the cup spout 32 and the mutual cooperation of the convex ring 315 and the inner wall of the annular concave cavity 321, thus remarkably improving the dustproof effect to prevent the external dust from entering the annular water outlet cavity 21, thus practically ensuring the health and safety of drinking water.

[0045] Finally, it should be noted that: the above examples are only used to illustrate the technical solutions of the utility model, and not to limit them; although the utility model has been described in detail with reference to the foregoing examples, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing examples, or equivalently replace some technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the utility model.
