Detailed Embodiments

[0041] In order to make the objectives, technical solutions and advantages of the present invention more clear and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0042] The following describes the specific implementation of the present invention in detail with reference to specific embodiments.

[0043] Embodiment 1

[0044] As shown in the Figure 1 accompanying drawings, a cup lid provided by an embodiment of the present invention includes:

[0045] a lid body 100;

[0046] An elastic component 102 is provided on the lid body 100, and a locking rod 101 is provided on the elastic component 102;

[0047] When the elastic component 102 is compressed, the elastic component 102 can drive the locking rod 101 to move towards the axis of the lid body 100; when the elastic component 102 is released from compression, the elastic component 102 can drive the locking rod 101 to return to its original position.

[0048] The cup lid of the embodiment of the present invention is applicable to a cup body 200 having a locking ring 201 at the cup mouth 202, and its use process is as follows:

[0049] Assume that in the initial state, the cup lid is separated from the cup body 200. When performing the cup-locking operation, just press the cup lid down from the cup mouth 202. When the locking rod 101 in the cup lid passes through the locking ring 201 of the cup body 200, the locking ring 201 will exert a compressive force on the elastic component 102 of the cup lid. Then the elastic component 102 drives the locking rod 101 to move towards the axis of the lid body 100, so that the locking rod 101 passes downward through the locking ring 201. After the locking rod 101 passes through the locking ring 201, the locking ring 201 no longer exerts a compressive force on the elastic component 102. Then the elastic component 102 drives the locking rod 101 to return to its original position, so that the locking rod 101 and the locking ring 201 form a locked state, that is, the cup is in the cup-locked state.

[0050] When performing the unlocking operation, just pull the cup lid out from the cup mouth 202. When the locking rod 101 in the cup lid passes through the locking ring 201 of the cup body 200, the locking ring 201 will exert a compressive force on the elastic component 102 of the cup lid. Then the elastic component 102 drives the locking rod 101 to move towards the axis of the lid body 100, so that the locking rod 101 passes upward through the locking ring 201. After the locking rod 101 passes through the locking ring 201, the locking ring 201 no longer exerts a compressive force on the elastic component 102. Then the elastic component 102 drives the locking rod 101 to return to its original position, and the entire cup lid leaves the cup mouth 202 of the cup body 200, that is, the cup is in the unlocked state.

[0051] Both the above-mentioned cup-locking and unlocking operations can be completed with one hand only.

[0052] In addition, in this embodiment, the elastic elements in the elastic component 102 can be various elastic elements such as springs and elastic rubbers; multiple lock rods 101 can be provided according to actual needs. For example, Figure 1 in the cup lid example provided, three lock rods 101 are provided, and correspondingly, three groups of elastic components 102 are also provided.

[0053] Compared with the prior art, for one thing, the cup lid of the present invention only needs one hand to complete the cup-locking and unlocking operations, without the need to unscrew the pop-up lid like a pop-up lid water cup, nor the need for two hands to operate like an internally threaded water cup, which is more convenient and faster; for another, compared with the pop-up lid water cup, there is no pop-up lid part that is not conducive to cleaning, and compared with the internally threaded water cup, there is no threaded part, so there will be no accumulation of scale and tea stains, and no bacteria problems, which is more convenient for the cleaning and maintenance of the cup; for the third, due to the absence of the threaded part, the wear between the cup lid and the cup mouth 202 is reduced, and the use experience of consumers is improved.

[0054] As shown in the appendix Figure 2 As a preferred embodiment of the present invention, the cup lid further includes:

[0055] A turntable 103, which is arranged on the cover body 100; the turntable 103 has fixing holes 111;

[0056] A gear 104, which is used to drive the turntable 103 to rotate; the gear 104 meshes with the lock rod 101; when the lock rod 101 moves towards or returns to the axis of the cover body 100, the lock rod 101 can drive the gear 104 to rotate;

[0057] A pressing piece 106 embedded with a fixing pin 105, which is arranged on one side of the turntable 103;

[0058] A motor 107, which is used to drive the fixing pin 105 on the pressing piece 106 to insert into or pull out from the fixing hole 111 of the turntable 103.

[0059] Specifically, this embodiment adds a locking function to the cup-locking operation. When the cup is in the cup-locked state, the motor 107 drives the fixing pin 105 on the pressing piece 106 to insert into the fixing hole 111 of the turntable 103 to fix the turntable 103 to prevent the turntable 103 from rotating, so that the elastic component 102 cannot drive the lock rod 101 to move towards the axis of the cover body 100, that is, the cup is in the locked state.

[0060] When unlocking is required, the fixed bolt 105 on the pressing piece 106 is driven by the motor 107 to be pulled out from the fixed hole 111 of the turntable 103, so that the turntable 103 can rotate, and the elastic component 102 can drive the lock rod 101 to move towards the axis of the cover body 100, and the cup can be normally unlocked.

[0061] The motor 107 in this embodiment can be a stepper motor. The motor 107 in this embodiment only drives the fixed bolt 105 to insert into or be pulled out from the fixed hole 111 of the turntable 103, which can reduce power consumption and ensure the airtightness of the cup lid.

[0062] As a preferred embodiment of the present invention, the cup lid further includes:

[0063] A display screen embedded with an under-screen fingerprint unlocking module and a pressure sensor, which is arranged on the cover body 100;

[0064] A control module 113; the display screen can receive fingerprint information; when the fingerprint information received by the display screen is successfully verified by the fingerprint unlocking module, the control module 113 can control the motor 107 to drive the fixed bolt 105 on the pressing piece 106 to be pulled out from the fixed hole 111 of the turntable 103.

[0065] Specifically, this embodiment provides a fingerprint unlocking function for the cup lid. When the user performs an unlocking operation, just place the finger on the display screen, and the fingerprint unlocking module under the display screen can verify the fingerprint information received by the display screen. After successful verification, the fingerprint unlocking module sends a successful verification instruction to the control module 113. After receiving the successful verification instruction, the control module 113 controls the motor 107 to start. The motor 107 drives the fixed bolt 105 on the pressing piece 106 to be pulled out from the fixed hole 111 of the turntable 103, so that the turntable 103 can rotate, and the cup can be normally unlocked. Attached Figure 3 A schematic diagram of the display state of the display screen when verifying fingerprints is provided.

[0066] When non-finger objects accidentally touch the display screen, the fingerprint unlocking module under the display screen will not issue a successful verification instruction, and the cup remains in the locked state.

[0067] As shown in the attachment Figure 1 As a preferred embodiment of the present invention, the cup lid further includes:

[0068] A Hall sensor, which is electrically connected to the control module 113;

[0069] The magnetic member 112 is disposed on the turntable 103. When the turntable 103 rotates, the magnetic member 112 causes a changing Hall voltage to be generated in the Hall sensor, and the control module 113 controls the display screen to display a locked cup icon or an unlocking icon according to the changing Hall voltage. When the control module 113 controls the display screen to display the locked cup icon, the control module 113 can simultaneously control the motor 107 to drive the fixed pin 105 on the pressing piece 106 to insert into the fixed hole 111 of the turntable 103.

[0070] Specifically, this embodiment provides a locked cup reminder, an unlocking reminder, and an automatic locked cup function for the cup lid.

[0071] For the unlocking operation, when the fingerprint recognition is correct, the control module 113 controls the motor 107 to lift the fixed pin 105, and at the same time the Hall sensor starts to work. When the cup lid is taken out upward, the cup lid passes through the vertex of the lock ring 201, the lock ring 201 compresses the elastic component 102, and the elastic component 102 drives the lock rod 101 to move toward the axis of the lid body 100. The lock rod 101 drives the turntable 103 to rotate to the maximum position through the gear 104. At this time, the Hall voltage of the Hall sensor reaches the maximum value. After passing through the vertex of the lock ring 201, the elastic component 102 ejects the lock rod 101. When the turntable 103 returns to the initial position, the Hall voltage of the Hall sensor reaches the minimum value, and the cup lid is in the unlocked state. At this time, the control module 113 controls the display screen to display the unlocking icon according to the change of the above Hall voltage. The rotation state of the turntable 103 is as shown in the appendix Figure 4 as shown.

[0072] For the locked cup operation, when the cup lid is pressed into the cup body 200 in the unlocked state, when passing through the vertex of the lock ring 201, the lock ring 201 compresses the elastic component 102, and the elastic component 102 drives the lock rod 101 to move toward the axis of the lid body 100. The lock rod 101 drives the turntable 103 to rotate to the maximum position through the gear 104. At this time, the Hall voltage of the Hall sensor reaches the maximum value. After passing through the vertex of the lock ring 201, the elastic component 102 ejects the lock rod 101, and the turntable 103 returns to the initial position. The Hall voltage of the Hall sensor reaches the minimum value, and the cup lid state becomes the locked cup state. At this time, the control module 113 controls the display screen to display the locked cup icon according to the change of the above Hall voltage, and controls the motor 107 to drive the fixed pin 105 on the pressing piece 106 to insert into the fixed hole 111 of the turntable 103, so that the cup is in a locked state. The appendix Figure 3 provides a state diagram showing the locked cup icon displayed on the display screen.

[0073] As shown in the appendix Figure 5 As shown, as a preferred embodiment of the present invention, the cup lid further includes:

[0074] A temperature sensor 109, electrically connected to the control module 113, is used to detect the temperature information of the water body; the temperature information detected by the temperature sensor 109 can be displayed on the display screen.

[0075] Specifically, this embodiment provides a temperature detection function for the cup. The temperature information detected by the temperature sensor 109 is sent to the control module 113, and the control module 113 controls the display screen to display the temperature information detected by the temperature sensor 109. Using the above function, users can know the water temperature in the cup, avoiding drinking cold water with too low a temperature or being scalded by hot water with too high a temperature. Attached Figure 3 A schematic diagram of the display state when the display screen shows the temperature is provided.

[0076] As Figure 5 shown, as a preferred embodiment of the present invention, the cup lid further includes:

[0077] A water quality detection sensor 110, electrically connected to the control module 113, is used to detect the PPM information of the water body; the water quality information detected by the water quality detection sensor 110 can be displayed on the display screen.

[0078] Specifically, this embodiment provides a water quality detection function for the cup. The PPM information of the water is detected by the water quality detection sensor 110 to ensure the drinking water safety of users.

[0079] As a preferred embodiment of the present invention, the cup lid further includes:

[0080] A six-axis sensor, electrically connected to the control module 113, is used to detect the attitude of the lid body 100.

[0081] Specifically, this embodiment provides an attitude detection function for the cup lid. The attitude information of the lid body 100 is detected by the six-axis sensor to judge the position and pose of the lid body 100. For example, when the user lifts the cup, the six-axis sensor detects that the cup lid is in the lifted state and sends a lifted state signal to the control module 113. After receiving the lifted state signal, the control module 113 issues a temperature display instruction to control the display to display the temperature information detected by the temperature sensor to guide the user to drink water. Another example is when the cup is in the locked cup state and the attitude of the lid body 100 is in the inverted state, the six-axis sensor detects that the cup lid is in the inverted state and sends an inverted state signal to the control module 113. After receiving the inverted state signal, the control module 113 issues a water quality detection instruction to control the display to display the PPM information detected by the water quality detection sensor 110 to guide the user to drink water safely.

[0082] As Figure 6 shown, as a preferred embodiment of the present invention, the cup lid further includes:

[0083] The bottom cover sealing rubber ring 108 is arranged inside the cover body 100.

[0084] Specifically, in this embodiment, the sealing performance of the cup cover is improved by arranging the bottom cover sealing rubber ring 108, ensuring the airtightness of the cup.

[0085] Embodiment 2

[0086] As shown in the Figure 6 accompanying drawings, an embodiment of the present invention further provides a heat-insulated cup, comprising:

[0087] The cup cover according to any one of Embodiment 1;

[0088] A cup body 200; a locking ring 201 is provided at the cup mouth 202 of the cup body 200; when the locking rod 101 of the cup cover passes through the locking ring 201, the locking ring 201 can compress the elastic component 102 of the cup cover.

[0089] Specifically, the locking ring 201 at the cup mouth 202 in this embodiment is designed with a semicircular cross-section. When lifting or pressing down the cup cover, the fixed bolt 105 will decompose the force into two directions, X and Y. The component force in the X direction is used to compress the elastic member to open the cup cover.

[0090] The heat-insulated cup of the embodiment of the present invention has all the advantages of the cup cover in Embodiment 1. Through the bolt lock structure and in combination with the fingerprint unlocking technology, users can easily meet the requirement of opening the cup with one hand. The motor 107 only controls the fixed bolt 105, which can reduce the power consumption of the heat-insulated cup, providing a threadless heat-insulated cup with a simple structure, operable with one hand, low power consumption, and good airtightness.

[0091] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
