DETAILED DESCRIPTION

[0026] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

The temperature sensing head 4 is made of food contact grade stainless steel and can be directly inserted into the cover body 1 to transmit temperature.

[0029] The temperature display 2 is purely mechanical, highly safe, poses no threat to human health, does not require charging, has a long service life, and is more durable.

[0030] In order to ensure the reliability of the cover body 1, the cover body 1 includes an upper cover 5 and a lower cover 6, which are rotatably connected; a locking mechanism 7 is provided between the upper cover 5 and the lower cover 6, and the locking mechanism 7 is used to lock or unlock the upper cover 5 and the lower cover 6, and the upper cover 5 has a tendency to open outward; the mechanical temperature display dial 3 is arranged on the locking mechanism 7. In this embodiment, the upper cover 5 and the lower cover 6 are hinged, and the upper cover 5 has a tendency to open outward through a torsion spring, and the locking mechanism 7 is arranged opposite to the hinge point of the upper cover 5 and the lower cover 6; the lower cover 6 is provided with a first through hole 29 that is connected to the inside of the lower cover 6, and the temperature sensor head 4 extends into the inside of the lower cover 6 through the first through hole 29 to facilitate temperature transmission. The design of the upper cover 5 and the lower cover 6 can improve the protection against the pouring spout or the straw; the traditional thermos cup usually distinguishes the display area from the switch area, resulting in the cup cover being too large and the switch being too small, lacking in convenience and comfort of use. The mechanical temperature display dial 3 and the locking mechanism 7 are arranged in the same area, which reduces the space occupied and thus can reduce the cup cover volume.

[0031] In order to make the locking mechanism 7 reliable, Figure 3 , Figure 4 As shown, the locking mechanism 7 includes a first clamping block 8, a first buckle slot 9 and a rotating member 10. The first clamping block 8 cooperates with the first buckle slot 9. The first buckle slot 9 is located in one of the upper cover 5 or the lower cover 6, and the first clamping block 8 is located in the other; the rotating member 10 is used to rotate one of the first clamping block 8 or the first buckle slot 9 to unlock the first clamping block 8 and the first buckle slot 9. The design of the first clamping block 8 and the first buckle slot 9 makes locking simple and reliable; the rotating member 10 drives one of the first clamping block 8 or the first buckle slot 9 to rotate synchronously, so that the first clamping block 8 and the first buckle slot 9 are separated, and unlocking is simple and convenient.

[0032] In order to ensure the reliability of the locking mechanism 7, the first buckle groove 9 is located on the upper cover 5, and the first clamp block 8 is located on the lower cover 6; the locking mechanism 7 includes a linkage member 11, the rotating member 10 is connected to the linkage member 11 and rotates synchronously, and the linkage member 11 is rotationally connected to the lower cover 6; the mechanical temperature display dial 3 is arranged between the rotating member 10 and the linkage member 11, and a display port 12 is opened in the center of the rotating member 10, and the display port 12 is used to expose the mechanical temperature display dial 3, so as to facilitate the observation of temperature data. The mechanical temperature display dial 3 is arranged concentrically with the rotating member 10. The first clamp block 8 is arranged on the linkage member 11.

[0033] In order to ensure reliable connection between the linkage member 11 and the rotating member 10, Figure 5 , Figure 6 , Figure 7As shown, the linkage member 11 is provided with a second clamping block 13, and the rotating member 10 is provided with a second buckle groove 14, and the second clamping block 13 and the second buckle groove 14 cooperate with each other; the linkage member 11 is provided with a positioning groove 15, and the rotating member 10 is provided with a positioning block 16, and the positioning groove 15 and the positioning block 16 cooperate with each other. In this embodiment, four second clamping blocks 13 are provided and evenly distributed around the linkage member 11, and four second buckle grooves 14 are provided accordingly; two positioning grooves 15 are provided, and two positioning blocks 16 are provided accordingly. The design of the second clamping block 13 and the second buckle groove 14 makes the installation of the linkage member 11 and the rotating member 10 simple and reliable; the design of the positioning groove 15 and the positioning block 16 makes the installation of the linkage member 11 and the rotating member 10 precise, and the rotating member 10 drives the linkage member 11 to rotate more reliably.

[0034] In order to ensure reliable installation of the linkage member 11, a fixing member 17 is provided between the linkage member 11 and the rotating member 10. The fixing member 17 is used to prevent the linkage member 11 from slipping out. The fixing member 17 is fixedly connected to the lower cover 6 and is rotatably connected to the linkage member 11. An elastic member 18 is provided between the fixing member 17 and the linkage member 11. The elastic member 18 is used to reset the linkage member 11 after rotation to ensure reliable locking of the locking mechanism 7. The two sides of the mechanical temperature display dial 3 are respectively in contact with the fixing member 17 and the rotating member 10; in this embodiment, the elastic member 18 is a spring. Of course, the elastic member 18 can also be a torsion spring, a spring, etc.

[0037] In order to facilitate the rotation of the rotating member 10 , a protruding toggle member 25 is provided on the rotating member 10 . The toggle member 25 can be more easily grasped by the user to facilitate the rotation of the rotating member 10 .

[0038] In order to improve the safety of opening the cover, the linkage member 11 is provided with a fourth clamping block 26, which is arranged with the first clamping block 8 relative to the first buckle groove 9, and the lowest point of the fourth clamping block 26 is higher than the highest point of the first clamping block 8; when the first clamping block 8 is buckled with the first buckle groove 9, the highest point of the first buckle groove 9 is higher than the highest point of the fourth clamping block 26. The design of the fourth clamping block 26 allows the fourth clamping block 26 to buckle into the first buckle groove 9 after the first clamping block 8 is unlocked from the first buckle groove 9, blocking the upper cover 5 from automatically popping outward, which can prevent the cover from opening too quickly and injuring people or the hot water in the thermos cup from splashing out and scalding people under the action of air pressure, thereby improving safety.

[0039] The linkage member 11 is provided with a second protrusion 30 extending toward the center of the lower cover 6, and the second protrusion 30 is provided with a second through hole 31. The first clamping block 8 and the fourth clamping block 26 are located on opposite sides of the hole wall of the second through hole 31. The lower cover 6 is provided with a third through hole 32. In the locked state, the first buckle groove 9 passes through the third through hole 32 and enters the second through hole 31 to buckle with the first clamping block 8; the rotating member 10, the linkage member 11 and the fixed member 17 are all annular, and an annular groove 33 is provided on the lower cover 6 to facilitate the installation of the rotating member 10, the linkage member 11 and the fixed member 17 on the lower cover 6.
