[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application. In addition, the technical solutions of various embodiments can be combined with each other, but this must be based on the ability of those of ordinary skill in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection of this application.

[0022] In the embodiments of this application, please refer to Figure 1-4 As shown, this application provides a water cup with a safety lock, mainly comprising: a cup body 1 and a cup lid 2. The cup body 1 and the cup lid 2 are provided with a first connecting part 3 and a second connecting part 4, wherein the first connecting part 3 is provided on either the cup body 1 or the cup lid 2, and the second connecting part 4 is correspondingly provided on the other. The first connecting part 3 can be nested on the outside of the second connecting part 4. A sliding groove 31 is provided on the first connecting part 3, and a button 32 is slidably disposed in the sliding groove 31. A locking part 41 is provided on the second connecting part 4, which cooperates with the sliding groove 31. The locking part 41 can drive the button 32 to move outward from the first connecting part 3, so that the button 32 is converted to a pressable state and inserted into the sliding groove 31 to lock the cup body 1 and the cup lid 2. By pressing the button 32, the locking part 41 can be driven to leave the sliding groove 31 to unlock the cup body 1 and the cup lid 2. A bimetallic strip 5 is provided on the sliding groove 31. When the temperature inside the cup body 1 exceeds a preset threshold, the bimetallic strip 5 deforms and mechanically locks the button 32, making it impossible to press.

[0023] Specifically, when the cup lid 2 is assembled onto the cup body 1, the first connecting part 3 and the second connecting part 4 can contact each other. The button 32 located on the first connecting part 3 can slide in the sliding groove 31, so that the locking part 41 can drive the button 32 to move outward. When the button 32 is not pressed to drive the locking part 41 away from the sliding groove 31, the first connecting part 3 and the second connecting part 4 enter the locked state, and the button 32 enters the pressable state. At the same time, the outward movement of the button 32 can provide space for the bimetallic strip 5 to deform. After the bimetallic strip 5 is deformed, it will occupy the space of the sliding groove 31. Since the bimetallic strip 5 is made of metal, it will not be broken by the button 32, ensuring that the user cannot press the button 32 to unlock when the temperature inside the cup body 1 reaches the threshold.

[0024] The following will continue to describe some preferred / improved embodiments based on the above embodiments. Any one of the following embodiments can be selected, or multiple embodiments can be combined.

[0025] Specifically, to ensure that the first connecting part 3 can be fitted over the second connecting part 4, both the first connecting part 3 and the second connecting part 4 are annular structures, and the diameter of the first connecting part 3 is larger than the diameter of the second connecting part 4. At the same time, the first connecting part 3 and the second connecting part 4 can serve as normal connection methods, allowing the cup lid 2 and the cup body 1 to be locked and sealed by means such as threaded connection or magnetic connection.

[0026] Preferably, in order to prevent the button 32 from leaving the sliding groove 31 during the pressing process or when it is lifted by the locking part 41, both ends of the button 32 are provided with protruding edges 321. The protruding edge 321 at one end of the button 32 slides in the sliding groove 31, and the protruding edge 321 at the other end is provided outside the first connecting part 3. The protruding edge 321 located in the sliding groove 31 can cooperate with the inner wall of the sliding groove and serve as a seal for the sliding groove 31. The protruding edge 321 located outside the first connecting part 3 can serve as a force-applying surface for pressing the button 32.

[0027] Reference Figure 2-4 As shown, in order to enable the protrusion 321 of the button 32 to be positioned so that it can be lifted by the locking part 41 and play a certain sealing role under normal conditions, a first magnet 33 is provided on the other side of the sliding groove 31 where the bimetallic strip 5 is provided, and a second magnet 322 that cooperates with the first magnet 33 is provided on the protrusion 321.

[0028] Specifically, in order to prevent the cup lid 2 from being interfered with by the locking part 41 during installation and to be able to lift the button 32, the locking part 41 includes a locking block 411 and a spring 412. A spring groove 413 is provided in the second connecting part 4. At least a part of the locking block 411 is located in the spring groove 413. The spring 412 is disposed in the spring groove 413 and can drive the locking block 411 to move outward at all times.

[0029] Preferably, the locking block 411 includes a limiting part 4111 and a locking part 4112. The limiting part 4111 is placed in the spring groove 413, and the locking part 4112 is designed with an inclined surface. This design allows the inclined locking part 4112 to provide room for the deformation of the bimetallic strip 5, and it can naturally retract when the cup lid 2 is assembled until it enters the range of the sliding groove 31.

[0030] The preset threshold is 70-90℃, and preferably, the preset threshold is 80℃. When the temperature is higher than 80℃, the bimetallic sheet 5 undergoes bending deformation, and when the temperature is lower than 80℃, the bimetallic sheet 5 remains unchanged or returns to its original state.

[0031] Specifically, in order to ensure that the bimetallic strip 5 can stably block the sliding groove 31 when it deforms and can completely reset after the temperature drops, the bimetallic strip 5 includes a fixed end 51 and a movable end 52. The bimetallic strip 5 is fixedly installed in the sliding groove 31 through the fixed end 51, and the movable end 52 can bend to block the pressing path of the button 32 when the temperature in the cup body 1 exceeds a preset threshold.

[0032] For illustrative purposes, the bimetallic strip 5 should be in a flat state under normal conditions and can be used as the inner wall of the sliding groove 31. After deformation, the bimetallic strip 5 bends towards the center of the sliding groove 31.

[0033] The various embodiments of this application have now been described in detail. To avoid obscuring the concept of this application, some details known in the art have not been described. Those skilled in the art can fully understand how to implement the technical solutions disclosed herein based on the above description.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of this application. The foregoing embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
