[0016] Please refer to Figures 1 to 5The thermos cup shown in the figure comprises a first upper lid assembly 1, a first lower lid assembly 2, and a cup body 5. The first upper lid assembly 1 contains a drive mechanism 31, which drives the first sliding sleeve 21 of the locking mechanism to descend, thereby actuating the first connecting rod 212 and the first latch 213 to complete the locking operation. This drive mechanism 31 can be any existing electric or manual method, and is not specifically limited in this embodiment. The first lower lid assembly 2 is used for fastening with the first upper lid assembly 1, facilitating cleaning and maintenance of the entire lid. It also serves as the latch for the cup body 5, making assembly of the lid and body easier. The main innovation of the first lower lid assembly 2 lies in the first locking mechanism 21, which will be described in detail later. To form a locking relationship with the first locking mechanism 21, the cup body 5 has an inwardly recessed groove 51 structure at a corresponding position.

[0017] The first lower cover assembly 2 in the figure mainly includes a first locking mechanism 21, a lower top cover 22, and a lower bottom cover 23. The lower top cover 22 and lower bottom cover 23 are mainly used for limiting and fixing the first locking mechanism 21. The first locking mechanism 21 mainly includes a first sliding sleeve 21, a first connecting rod 212, a first latch 213, and a first sliding sleeve spring 214. The first sliding sleeve 21 is used to drive the first connecting rod 212 to move through a hinge, and then the first connecting rod 212 also drives the first latch 213 to perform a lateral locking action through a hinge. The first sliding sleeve spring 214 is used to reset the first sliding sleeve 21.

[0018] The first sliding sleeve 21 in the figure has a hollow cavity structure at its top, which facilitates the downward pushing of the drive mechanism 31 of the first upper cover assembly 1 at this cavity position, thereby causing it to descend. The first sliding sleeve 21 has a lateral protrusion on its side, which facilitates its fitting and positioning within the internal cavity of the lower top cover 22. Three sets of evenly arranged first connecting blocks 2111 are designed at the lower edge of the lateral protrusion. Each set of first connecting blocks 2111 consists of two mutually spaced first connecting blocks 2111. Each first connecting block 2111 has a hinge hole design, which facilitates subsequent hinged assembly with one end of the first connecting rod 212 at the spaced position. The first sliding sleeve 21 has a first sleeve rod 2112 that protrudes and extends towards the lower bottom cover 23 at the axis center position. This first sleeve rod 2112 facilitates the positioning of the entire first sliding sleeve 21 and cooperates with the first sliding sleeve spring 214 to achieve the reset of the first sliding sleeve 21. The number of first connecting rods 212 corresponds to the number of sets of first connecting blocks 2111. Each first connecting rod 212 adopts a rod-shaped structure, and both ends are designed with hinge holes. Each latch adopts an L-shaped design and has hinge holes at the hinge position with the first connecting rod 212.

[0019] The lower top cover 22 and lower bottom cover 23 in the figure are designed with a limiting groove 6 at the interface where they are joined, which limits the movement of the first latch 213. The lower top cover 22 and lower bottom cover 23 can be assembled together by snap-fit. The lower top cover 22 has a cavity structure inside, which facilitates the upper middle position of the first sliding sleeve 21 to be limited and fixed in the cavity. The lower bottom cover 23 has a longitudinal first positioning rod 231 structure designed at the axis center position. The first positioning rod is fitted inside the first sleeve rod to position the first sleeve rod. At the same time, the bottom position of the lower bottom cover 23 can support the first sliding sleeve spring 214.

[0020] Please refer to Figures 6 to 10 The thermos cup in the figure is designed with a second upper cover assembly 3 and a second lower cover assembly 4; the cup body 5 is not shown in the figure because it is the same as in embodiment 1. The second upper cover assembly 3 and the second lower cover assembly 4 in the figure are also assembled by screw connection. The second upper cover assembly 3 is equipped with an electric or manual drive mechanism 31 to drive the second locking mechanism 41, and the second lower cover assembly 4 is equipped with a locking mechanism to complete the locking operation.

[0021] like Figure 10 As shown, the second upper cover assembly 3 employs a manual drive mechanism 31. This drive mechanism 31 includes a button 311, a button spring 312, and a ratchet 313. The button 311 is a T-shaped cylindrical structure with a guide block 3111, a first drive tooth 3112, and a push rod 3113. The guide block 3111 is positioned and assembled with the second upper cover 32 inside the second upper cover assembly 3. Specifically, the second upper cover 32 has a guide groove 321 at a corresponding position to assemble with the guide block 3111. The first drive tooth 3112 has a toothed structure, which, together with the second drive tooth 3131 on the ratchet 313, forms a cooperative relationship that drives the ratchet 313 to descend when the button 311 is pressed by external force. The push rod 3113 is inserted into the lower cover 42 to limit and fix the second upper cover 32. The button spring 312 is a conventional spring structure, with one end abutting against the inner wall of the top of the button 311 and the other end abutting against a component at the center of the ratchet 313 shaft, allowing the button 311 to return to its original position after being pressed. The ratchet 313 has a protruding positioning tooth 3132 structure on its outer wall, which corresponds to the guide groove 321 of the second upper cover 32, thereby limiting and fixing the ratchet 313 to the second upper cover 32. The interior of the second upper cover 32 is a hollow structure forming a movable hole 323 to facilitate the placement of the button 311. Simultaneously, a positioning platform 322 with an inclined surface is designed next to the guide groove 321, facilitating engagement with the inclined surface on the positioning tooth 3132 to form a positioning fit.

[0022] like Figure 8As shown, the second locking mechanism 41 in the figure is designed with a second sliding sleeve 411, a second connecting rod 412, a second lock 413, and a second sliding sleeve spring 414. The second sliding sleeve 411 is used to enable the second lock 413 to complete the locking operation via the second connecting rod 412. The second connecting rod 412 is used for the hinged connection assembly between the second sliding sleeve 411 and the second lock 413. The second lock 413 is used to lock or unlock the entire cup lid and cup body 5. The second sliding sleeve spring 414 is used for the reset of the second sliding sleeve 411. The second sliding sleeve 411 in the figure is designed with four sets of second connecting blocks 4111, each set having two mutually spaced second connecting blocks 4111. The second connecting blocks 4111 are designed with hinge holes. The second sliding sleeve 411 is also designed with a first sleeve rod 2112, which is used to fit onto the second positioning rod 421 of the lower cover 42 to limit and fix the second sliding sleeve 411. The second connecting rod 412 is a rod-shaped structure with hinge holes at both ends. One end of the second connecting rod 412 is hinged to the interval of the second connecting block 4111, and the other end is hinged to the second latch 413. The second latch 413 has an L-shaped design, and a hinge hole is designed at the hinge position with the second connecting rod 412. The second latch 413 is also located within the limiting groove 6 of the lower cover 42. There are four second connecting rods 412 and four second latches 413, which are evenly distributed. One end of the second sliding spring 414 abuts against the inner top wall of the second sliding sleeve 411, and the other end abuts against the bottom wall of the lower cover 42.
