[0036] In order to more clearly illustrate the present invention, the present invention will be further described below with reference to the accompanying drawings.

[0037] In the following description, examples are provided to provide a deeper understanding of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. It should be understood that the specific embodiments described are only for the purpose of explaining the present invention and are not intended to limit the present invention.

[0038] It should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of the stated features, integers, steps, operations, elements or components, but do not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components or combinations thereof.

[0039] In order to solve the above technical problems, this application provides a thermal insulation cup cover, please refer to the attached Figure 1 To the attached Figure 9, including a shell, a linkage disk 7, a drive motor 4, a lock pin 5 and an exhaust valve; the shell is used to connect with the external cup body and is provided with a accommodating chamber; the linkage disk 7 is located in the shell to divide the accommodating chamber into a first partition and a second partition, and a rotation gap is reserved between the side wall of the linkage disk 7 and the inner wall of the shell; the outer wall of the shell is provided with at least one lock pin opening connected to the first partition; the drive motor is placed in the second partition and is used to drive the linkage disk 7 to rotate; the lock pin 5 is located in the first partition and is extended and retracted in the lock pin opening based on the rotation of the linkage disk 7; the exhaust valve is located in the first partition, and when the lock pin is retracted to the first partition, the exhaust valve is connected to the lock pin opening;

[0040] The specific working principle is as follows: the user makes the driving motor 4 work through a specified action. When the driving motor 4 rotates forward, the linkage disk 7 follows the rotation of the driving motor 4, and makes the lock pin 5 extend out of the environment through the lock pin opening and abut against the inner wall of the cup body, thereby realizing a locked state; when changing from a locked state to an open state, the driving motor is first reversed, and the linkage disk 7 follows the reverse rotation of the driving motor 4, so that the lock pin 5 is retracted into the first partition. At the same time, the exhaust valve is started to form a conductive state, so that the water vapor in the cup body enters from the exhaust valve and is discharged from the lock pin opening, thereby realizing pressure relief and preventing the pressure in the cup body from changing suddenly, which may cause harm to the user, especially a child user. ; It is worth mentioning that the accommodating cavity is formed into a first partition and a second partition through the linkage disk 7, so that the driving motor 4 and other parts with larger working parts that are greatly affected by water vapor can be placed separately to prevent water vapor from directly affecting the driving motor 4 when the exhaust valve is turned on; the implementation method for the lock pin 5 to follow the linkage disk 7 to rotate can be: a corresponding movable protrusion 51 is set on the lock pin 5, and a corresponding movable groove 71 is set on the linkage disk 7, and the movable protrusion 51 slides in the movable groove 71. When the linkage disk 7 follows the rotation of the drive motor 4, it can drive the lock pin 4 to extend or retract through the movable protrusion 51 and the movable groove 71. The movable groove 71 can be an arc groove or an oblique groove.

[0041] It can be seen that by adding an exhaust valve to discharge water vapor from the lock pin mouth when the lid is opened, the air pressure in the cup body and the environment can be balanced, preventing the liquid in the cup body from splashing out and injuring the user due to the cup lid popping out; on the other hand, the first partition and the second partition are formed by the linkage disk to prevent the drive motor from failing due to interference from water vapor.

[0042] In this embodiment, the shell is composed of a first sleeve 1 and a second sleeve 2, and the open convex ring 11 of the first sleeve 1 is fitted to the inner wall of the second sleeve 2; the outer wall of the first sleeve 1 and the inner wall of the second sleeve 2 are spaced apart to form a connection portion connected to the external cup body; the lock pin opening is provided on the outer wall of the first sleeve; it is not difficult to understand that by forming the shell into a structural style enclosed by the first sleeve 1 and the second sleeve 2, the difficulty of assembly is reduced, and the first sleeve 1 serves as the main sealing structure for the cup body, and the one-piece molding can ensure the sealing performance.

[0043] In this embodiment, it also includes a main control board 3 located in the second partition and electrically connected to the drive motor 4, and an identification module electrically connected to the main control board 3, the identification module forming an operating surface on the outer wall of the second sleeve; it also includes a movable ring 6 movably sleeved on the first sleeve, the movable ring 6 is provided with a connecting column 61 that passes through the open convex ring to extend into the second partition, the connecting column 61 is located between the open convex ring 51 and the movable ring 6, and the cylindrical portion is sleeved with a first elastic member 62; the extending end of the connecting column 61 is provided with a magnet 63; the main control board 3 is also equipped with a Hall switch for adapting to the magnet 63; the user's identity is identified by the identification module, thereby preventing anyone from opening the cup cover. The identification module is fingerprint recognition, eye recognition, face recognition or password recognition, etc. This part is existing technology, so it will not be elaborated on; the mechanism of this embodiment is further explained in combination with the above scheme: when the thermos cup cover is in a locked state, the lock pin 5 provides a force to squeeze the outer wall of the cup body through the drive motor 4, and the movable ring 6 When the user wants to change the locked state to the open state for drinking water, the user first needs to authenticate the user's identity through the identification module. If the identity matching fails, there will be no response. If the identity authentication is successful, the driving motor 4 will turn to make the locking pin 5 release the squeeze on the inner wall of the cup and retract into the first sleeve 1. At this time, the movable ring 6 drives the outer cup body of the entire thermos cup lid to pop out by the elastic potential energy accumulated by the first elastic member 62, and it can be opened without the user applying a twisting force. During the opening process, the exhaust valve works to achieve the above-mentioned effect of balancing the air pressure in the cup body. When closing again after drinking water, by continuously pressing the thermos cup lid, the movable ring 6 drives the magnet 63 to approach the expected detection position of the Hall switch of the main control board 3 to generate an opening signal. In response to the opening signal, the main control board 3 controls the driving motor 4 to start, and the driving motor 4 drives the locking pin 5 to extend, finally realizing the locking of the thermos cup lid and the outer cup body.

[0044] It can be seen that in the process of switching between the overall open and locked states, since the threaded structure in traditional technology is not introduced, the user can quickly use the thermos cup lid without applying twisting force, and automatic locking and opening are achieved during use, which makes the user experience better, the operation more convenient, and more suitable for children.

[0045] In a more optimal solution, in order to make the movable ring 6 work more stably, this embodiment also includes multiple groups of second elastic members, one end of the second elastic member is connected to the movable ring 6, and the other end is connected to the open convex ring 11; it is not difficult to understand that the second elastic member and the first elastic member 62 are evenly arranged around the movable ring 6 in position, so that the thermos cup cover will not tilt when it pops up; the second elastic member can be a spring, a shrapnel or a polymer elastic material, etc.

[0046] As for the specific setting of the exhaust valve, it can be opened together by induction of the solenoid valve or proportional valve to drive the motor to turn, so as to realize coordinated opening when the lock pin 5 retracts. In order to further discharge the influence of water vapor on the electronically controlled valve body and effectively reduce costs, a convex condition 74 is further provided on the side of the linkage disk 7 facing the first partition, and the end surface of the convex condition 74 forms an extrusion slope 75; the end surface of the first sleeve 1 is provided with a piston hole 12 connected to the lock pin port for avoiding the extension and retraction of the lock pin 5, and the exhaust valve is a piston member 8, one end of the piston member 8 abuts against the extrusion slope 75, and the other end is through The piston hole protrudes from the end face of the first sleeve or retracts to the first partition to control the open or blocked state of the piston hole; it is not difficult to understand that in the open state, the lock pin 5 retracts into the first partition, and the piston member 8 retracts into the first partition based on the different abutment heights of the extrusion slope, and the piston hole 12 is connected to the lock pin mouth. At this time, high-temperature hot air enters the first partition from the piston hole and is then discharged from the lock pin mouth to achieve air pressure balance and prevent the cup cover from spraying out; in the locked state, the abutment slope causes the piston member to seal the piston hole, thereby achieving overall sealing of the cup body and preventing the water medium in the cup body from flowing out.

[0047] As an improvement to the piston member, in this embodiment, the cylindrical surface of the piston member 8 is further provided with an abutment ring 81, and a sealing portion 83 is provided at one end close to the piston hole. A spring member 82 is sleeved between the abutment ring 81 and the sealing portion 83, and one end of the spring member 82 abuts against the abutment ring 81, and the other end abuts against the inner wall of the first sleeve 1; a gap is formed between the hole wall of the piston member 8 and the hole wall of the piston hole 12, and the sealing portion abuts based on the abutment of the abutment inclined surface to generate a first position for blocking the piston hole 12 and a second position for making the piston hole conductive; it is not difficult to understand that when the sealing portion 83 is in the first position, the sealing portion 83 abuts based on the spring The elastic force of the spring member 82 covers the piston hole 12 to achieve a sealed state. At this time, the lock pin 5 is also in a state of protruding out of the first sleeve 1; during the opening process, the drive motor 4 and the linkage disk 7 cooperate to drive the lock pin 5 to retract into the first partition, and the high surface of the extrusion slope squeezes the end of the piston member 8 to compress the spring member 82 and drive the blocking part to extend toward the center of the cup body. The hot air enters the first partition from the reserved spacing and is discharged into the environment from the lock pin 5 port. The structure is more ingenious and can better fit the rotation of the linkage disk to achieve the effect of unlocking and exhausting, closing and sealing, and is more convenient to use.

[0048] In this embodiment, in order to effectively reduce the assembly volume, in this embodiment, a driving rack 72 is further provided on the side of the linkage disk 7 close to the second partition, and the output shaft of the drive motor 4 is provided with a transmission tooth to be longitudinally assembled on the linkage disk 7; it is not difficult to understand that the forward or reverse rotation of the drive motor 4 drives the drive rack 72 to reciprocate, and the drive rack 72 drives the linkage disk 7 to form a corresponding forward or reverse rotation to drive the locking pin 5 to extend or retract; by driving the rack 72 to change the assembly position of the output shaft of the drive motor 4, a more compact assembly design is achieved.

[0049] In a more optimal solution, the end of the connecting column 61 that extends into the second sleeve 2 is also provided with an extension arm 64 extending toward the center of the main control board 3, and the magnet 63 is located on the extended end of the extension arm 64; the installation of the magnet 63 is achieved through the extension arm 64, which can make the main control board 3 located in the central area of ​​the second sleeve 2, and can reduce the protection thereof in actual falls. The installation of the magnet 63 through the extension arm 64 can better fit the central design of the main control board 3, and there is no need to worry about the working reliability of the Hall element.

[0050] In the preferred solution, a guide cylinder 73 is further provided on one side of the linkage disk 7 located in the second partition, and the extension arm 64 is provided with a guide column 65 adapted to the guide cylinder 73. Through the cooperation between the guide cylinder 73 and the guide column 65, the magnet 63 can move along the expected movement path, making the detection of the Hall switch more accurate and sensitive.

[0051] In this embodiment, the second partition also includes a mounting base 9, which is used to assemble the main control board 3 and a power battery electrically connected to the main control board 3; the mounting base 9 further protects the main control board 3 and the power battery, and the power battery can provide an adaptive voltage to enable the drive motor 4 and the identification module to work.

[0052] In this embodiment, the cylindrical surface of the first sleeve 1 is also provided with multiple groups of sliding grooves 13, and the inner wall of the movable ring 6 is provided with sliding protrusions 66 that are compatible with the movable grooves 71, so that the movable ring 6 can achieve more stable linear reciprocating motion on the cylindrical surface of the first sleeve 1 without offset causing movement jamming.

[0053] The present application also provides a thermos cup, comprising a cup body and any of the aforementioned thermos cup lids, the inner wall of the cup body being provided with a lock groove for a lock pin to extend into to form a locked state; the cup has the same structural function and beneficial effects as the aforementioned thermos cup lid, so no further details will be given.

[0054] The advantages of this utility model are:

[0055] 1. By adding an exhaust valve to discharge water vapor from the lock pin opening when the lid is opened, the air pressure inside the cup body and the environment is balanced to prevent the cup lid from popping out. On the other hand, the linkage disk is used to form the first and second partitions to prevent the drive motor from malfunctioning due to interference from water vapor.

[0056] 2. During the switching process between the overall opening and locking states, since the threaded structure in traditional technology is not introduced, the user can quickly use the thermos cup lid without applying twisting force. It can automatically lock and open during use, making the user experience better, the operation more convenient, and more suitable for children.
