[0032] The two height surfaces of the cam platform 15 have different bevel angles respectively. The motor head 53 is a lug structure. The slide rod 54 is adapted to the groove 6 .

[0033] The cup cover shell 2 and the cup cover liner 3 are prevented from falling off by the inverted structure inside the cup cover, and relative sliding is achieved by the rolling steel ball 13; the engagement threshold of the positive over-torque protection mechanism is specifically as follows: assuming that the initial elastic force applied by the first spring 43 to the steel ball 42 is g (unit Newton), the elastic coefficient is k, the rotation control mechanism 4 is rotated clockwise, the angle between the tangent plane of the steel ball 42 and the cam platform 15 is α, and the height of the engagement point between the steel ball 42 and the cam platform 15 is t1 (unit millimeter). When t1>t2, then α1<α, the engagement threshold F=g*tanα1=g*[\sqrt {{r}^{2}-{(rt)}^{2}} / (rt)] When t1≤t2, α1=α, engagement threshold F=g*tanα+k*(t2-t1), F in Newtons; when the rotation control mechanism 4 rotates clockwise, the angle α of the cam table 15 in contact with the steel ball 42 is not less than 45°; when the rotation control mechanism 4 rotates counterclockwise, the angle β of the cam table 15 in contact with the steel ball 42 is not greater than 45°

[0040] The working principle of the positive torque protection fingerprint unlocking thermos cup provided by the present invention is as follows:

[0041] The user places the cup lid in the cup body 1 and rotates the cup lid shell 2 clockwise, driving the rotation control mechanism 4 to rotate clockwise. The steel ball 42 touches the cam platform 15 and engages with it. When the engagement force is less than the engagement threshold, the steel ball 42 and the cam platform 15 are in an engaged state, causing the cup lid liner 3 to rotate synchronously clockwise and the cup lid to be tightened. When the engagement force exceeds the engagement threshold, the steel ball 42 and the cam platform 15 are in a slipping state, and the cup lid liner 3 does not rotate, realizing the over-torque cup lid screw protection; the cup lid shell 2 is rotated counterclockwise, driving the rotation control mechanism 4 to rotate counterclockwise, the steel ball 42 touches the cam platform 15 and always maintains a slipping state, realizing the cup lid locking function. Through the rotation of the micro motor 52, the second spring 55 pushes the slide rod into the groove 6 inside the cup lid liner 3. The cup lid shell 2 is rotated counterclockwise, and the cup lid liner 3 rotates synchronously with it counterclockwise, and the cup lid is opened.

[0042] Compared with related technologies, the positive torque protection fingerprint unlocking thermos cup provided by the present invention has the following beneficial effects:

[0043] The user places the cup lid in the cup body 1 and rotates the cup lid shell 2 clockwise, driving the rotation control mechanism 4 to rotate clockwise, and the steel ball 42 touches the cam platform 15 and engages with it. When the engagement force is less than the engagement threshold, the steel ball 42 and the cam platform 15 are in an engaged state, causing the cup lid liner 3 to rotate synchronously clockwise and the cup lid is tightened. When the engagement force exceeds the engagement threshold, the steel ball 42 and the cam platform 15 are in a slipping state, and the cup lid liner 3 does not rotate, realizing the over-torque cup lid screwing protection; rotate the cup lid shell 2 counterclockwise, driving the rotation control mechanism 4 to rotate counterclockwise, the steel ball 42 touches the cam platform 15 and always keeps a slipping state, realizing the cup lid locking function. Through the rotation of the micro motor 52, the slide rod is pushed into the groove 6 inside the cup cover liner 3 through the second spring 55, and the cup cover shell 2 is rotated counterclockwise, and the cup cover liner 3 rotates synchronously with it counterclockwise, and the cup cover is opened. It has a safety locking function, which can effectively lock the thermos cup to prevent people from taking it or using it by mistake, and also prevent malicious throwing of objects, which greatly improves safety. At the same time, the cup cover is easy to open and there will be no situation where the cup cover is stuck due to excessive torque. Example

[0044] Please refer to Figures 6-10 Based on the positive torque protection fingerprint unlocking thermos cup provided in the first embodiment of this application, the second embodiment of this application proposes another positive torque protection fingerprint unlocking thermos cup.

[0045] Specifically, the difference of the positive torque protection fingerprint unlocking thermos cup provided by the second embodiment of the present application is that it also includes a filter cover 16, the outer surface of the filter cover 16 is fixedly connected to a connecting block 17, and an open groove 18 is opened on the connecting block 17, the bottom of the cup body 1 is threadedly connected to a bottom cover 19, and the top of the bottom cover 19 is fixedly connected to a mounting groove 20, and two U-shaped limit blocks 21 are fixedly connected to the inner wall of the mounting groove 20, and two telescopic components 22 are provided at the bottom of the inner wall of the mounting groove 20, and the telescopic component 22 includes a fixed frame 221, and a sliding block 222 is slidably connected to the inside of the fixed frame 221, and a third spring 223 is provided between the bottom of the sliding block 222 and the bottom of the inner wall of the fixed frame 221, and the top of the sliding block 222 is fixedly connected to a push rod 224, and the top of the push rod 224 passes through the fixed frame 221 and extends to the top of the fixed frame 221.

[0046] The U-shaped limiting block 21 is adapted to the opening groove 18 , and the connecting block 17 is adapted to the installation groove 20 .

[0047] A rubber ring 23 is provided on the top of the bottom cover 19 .

[0048] The provision of the rubber ring 23 ensures the sealing between the bottom cover 19 and the cup body 1 .

[0049] The outer surface of the bottom cover 19 is provided with anti-slip grooves 24 .

[0050] The anti-slip grooves 24 increase the friction between the bottom cover 19 and the palm, so that the user will not slip when twisting the cover.

The fluorescent strip 26 can emit fluorescence at night, making it easier for the user to find the cup at night without touching the cup and causing it to tip over.

[0053] Compared with related technologies, the positive torque protection fingerprint unlocking thermos cup provided by the present invention has the following beneficial effects:

[0054] Place tea leaves or other soaked objects in the installation groove 20, then put the filter cover 16 into the installation groove 20, align the opening groove 18 with the U-shaped limit block 21, then push the filter cover 16 downward to move the connecting block 17 downward, so that the opening groove 18 passes through the U-shaped limit block 21, and the connecting block 17 moves downward to squeeze the push rod 224, so that the push rod 224 moves downward to indirectly squeeze the third spring 223, and then rotate the filter cover 16 to rotate the connecting block 17, so that the opening groove 18 and the U-shaped limit block 21 are misaligned. The connecting block 17 is stuck in the inside of the U-shaped limit block 21. After the filter cover 16 is loosened, the third spring 223 rebounds and applies force upward through the top rod 224, thereby fixing the connecting block 17 inside the U-shaped limit block 21, so that the filter cover 16 is fixed, and the tea leaves and other soaked materials can be restricted inside the mounting groove 20, so that they will not be drunk into the mouth during soaking. At the same time, when pouring tea leaves, the bottom cover 19 can be unscrewed, the filter cover 16 can be opened to clean out all the tea leaves, thereby preventing the presence of residues at the bottom of the cup when pouring tea leaves.
