[0027] The preferred embodiments of the present utility model will be described in detail below with reference to the drawings. Those skilled in the art will appreciate that these descriptions are only descriptive and exemplary and should not be construed as limiting the protection scope of the present utility model.

[0028] It should be noted that like reference numerals denote like elements in the following figures, and thus, once an element is defined in one figure, it may not be further defined or explained in subsequent figures.

[0029] This embodiment mainly describes the structure of a thermos cup lid, which is as follows:

[0030] As Figures 1-8 shown, a thermos cup lid includes a lid body 1. An installation part 6 for installing a straw assembly 3 and a cover 2 for covering the straw assembly 3 are provided on the lid body 1. The cover 2 is rotatably connected to the lid body 1. A switch assembly 4 for controlling the opening and closing of the cover 2 is also provided on the lid body 1. The straw assembly 3 includes an installation tube 31 installed in the installation part 6 and a first tube body 32 installed in the installation tube 31. The top of the first tube body 32 is located in the installation tube 31, and a first limit ring 36 is provided on the end face at the top of the first tube body 32. Then, a sucking tube 33 is sleeved and slidable on the first tube body 32 between the first limit ring 36 and the first limit. A sealing pad 38 is provided at the bottom of the sucking tube 33, and a spring 35 is sleeved on the first tube body 32 at the bottom of the sucking tube 33. The top of the spring 35 abuts against the bottom of the sucking tube 33. Finally, the bottom of the first tube body 32 passes through the installation part 6. Among them, a guiding groove 322 is formed on the tube wall of the first tube body 32, and a guiding block 332 matching the guiding groove 322 is provided on the inner wall of the sucking tube 33.

[0031] When the cover 2 is closed, the inner side of the cover 2 will squeeze the sucking tube 33, and the sucking tube 33 will move downward along the tube wall of the first tube body 32 in the mounting tube 31 until the cover 2 is completely closed. At the same time, the spring 35 in contact with the bottom of the sucking tube 33 will be compressed as the sucking tube 33 moves downward. In this way, there is no need to bend the sucking tube 33 when closing the cover 2, so that the sucking tube will not form a crease due to the closing of the cover 2, thus extending the service life of the sucking tube 33; when the cover 2 is opened, the inner side of the cover 2 no longer squeezes the sucking tube 33, so the spring 35 in contact with the sucking tube 33 starts to reset and elongate. In this way, the spring 35 can push the sucking tube 33, so that the sucking tube 33 can move upward along the tube wall of the first tube body 32 in the mounting tube 31 until the sucking tube 33 extends out of the mounting tube 31. The first limiting ring 36 provided on the first tube body 32 can prevent the sucking tube 33 from detaching from the first tube body 32 when moving upward, thus improving the reliability of the straw assembly 3. At the same time, as the sucking tube 33 moves upward, the bottom of the sucking tube 33 can abut against the first limiting ring 36. In this way, the sealing gasket 38 located inside the bottom of the sucking tube 33 can improve the sealing performance of the connection between the sucking tube 33 and the first tube body 32, thus further improving the reliability of the straw assembly 3. A guiding groove 322 is formed on the tube wall of the first tube body 32, and a guiding block 332 matching the guiding groove 322 is provided on the inner wall of the sucking tube 33. In this way, when the sucking tube 33 moves along the tube wall of the first tube body 32, it can be more stable.

[0032] Furthermore, the mounting tube 31 is inserted into the mounting portion 6, and the first tube body 32 is also inserted into the mounting portion 6. In this way, the straw assembly 3 can be taken out from the mounting portion 6 on the cup lid body 1, which facilitates the replacement of the straw assembly 3, and further facilitates the cleaning of the straw assembly 3. Then, a second limiting ring 34 is provided on the first tube body 32, and the second limiting ring 34 is located at the bottom in the mounting tube 31. At the same time, the top of the second limiting ring 34 abuts against the bottom of the spring 35. In this way, when the straw assembly 3 is used for a long time, the spring 35 can be prevented from damaging the mounting tube, thus extending the service life of the straw assembly 3. A plurality of through grooves 311 penetrating the first limiting ring 36 are formed in the tube wall at the top of the mounting tube 31. In this way, the elasticity of the mounting tube 31 can be improved, so that when the mounting tube 31 is inserted into the mounting portion 6, the mounting tube 31 can be more firmly fixed in the mounting portion 6. The mounting tube 31 is conically arranged, which facilitates the insertion of the mounting tube 31 into the mounting portion 6. A sealing layer 312 is provided on the outer wall of the mounting tube 31, and the mounting tube 31 is in close fit with the inner wall of the mounting portion 6 through the sealing layer 312. In this way, the sealing performance of the connection between the mounting tube 31 and the mounting portion 6 can be improved.

[0033] Further, a sealing ring 37 is provided at the connection between the first pipe body 32 and the installation part 6. The sealing ring 37 is sleeved on the first pipe body 32, and the outer wall of the sealing ring 37 is in close fit with the installation part 6, which can improve the sealing performance of the connection between the first pipe body 32 and the installation part 6.

[0034] A plurality of elastic baffles 331 are provided in the sucking pipe 33, and the elastic baffles 331 are all arranged circumferentially around the inner wall of the sucking pipe 33. The elastic baffles 331 are all arranged in an upward convex arc shape. By installing a plurality of elastic baffles 331 in the sucking pipe 33, foreign objects can be prevented from entering the thermos cup through the sucking pipe 33, thereby improving the safety of the beverage in the thermos cup. The elastic baffles 331 are all arranged in an upward convex arc shape, which can improve the supporting effect of the elastic baffles 331, thereby improving the reliability of the elastic baffles 331 to block foreign objects.

[0035] A pull ring 5 is rotatably arranged on the cup cover main body 1. When the pull ring 5 is attached to the cup cover main body 1, the pull ring 5 can block the switch assembly 4, which can make the switch assembly 4 on the cup cover main body 1 have an anti-misoperation effect, thereby improving the practicability of the cup cover. When the pull ring 5 is rotated and the pull ring 5 is away from the cup cover main body 1, the pull ring 5 can facilitate the user to take the thermos cup.

[0036] An elastic pressing block 7 is provided in the cover 2, and a plug 71 matching the inner diameter of the sucking pipe 33 is provided at the bottom of the elastic pressing block 7. When the inner side of the cover 2 presses the sucking pipe 33, the elastic pressing block 7 will not cause wear to the sucking pipe 33, thereby further improving the service life of the sucking pipe 33. With the setting of the plug 71, when the cover 2 is closed, the elastic pressing block 7 can press the sucking pipe 33, so that the sucking pipe 33 will retract into the installation pipe 31, and the plug 71 can block the sucking pipe 33, so as to avoid the beverage in the thermos cup from flowing out through the sucking pipe 33.

[0037] Due to the different capacities of the thermos cup, its length dimension is also different. Therefore, in order for the straw assembly 3 to be used normally, a second pipe body 39 is sleeved at the bottom of the first pipe body 32. A limiting groove is opened on the pipe wall at the bottom of the first pipe body 32, and a third limiting ring 321 is sleeved in the limiting groove. The first pipe body 32 is in interference connection with the second pipe body 39 through the third limiting ring 321, which can ensure the firm connection between the first pipe body 32 and the second pipe body 39. The setting of the limiting groove facilitates the installation of the third limiting ring 321.
