[0027] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0028] It should be noted that like reference numerals denote like items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.

[0029] This embodiment mainly describes a digital display cup cover with high sealing performance, as follows:

[0030] like Figures 1 to 8 As shown, a digital display cup cover with high sealing performance is used in conjunction with a cup body. The cup cover of the utility model is screwed on the cup mouth of the cup body. The cup cover includes a lower cover 1 and an upper cover 2 hinged to one side of the lower cover 1. The side of the lower cover 1 away from the hinge is provided with a lock 4 that can lock the upper cover 2 on the lower cover 1. The lower cover 1 is provided with a drinking port 11. When the upper cover 2 is opened, water can be drunk through the drinking port 11. A transparent top cover 3 is fixed on the top of the upper cover 2. The bottom of the top cover 3 is fixed with a lower cover 1. The mounting chamber 5 extends to the mounting chamber 5, which is used to mount the temperature digital display device 7. A connecting hole 51 corresponding to the drinking water port 11 is provided in the mounting chamber 5. A sealing gasket 6 that fits tightly with the bottom of the mounting chamber 5 is provided at the bottom of the mounting chamber 5. The sealing gasket 6 is used to isolate the mounting chamber 5 from the lower cover 1 to prevent water vapor or water in the cup body from entering the mounting chamber, causing water to enter the temperature digital display device 7 in the mounting chamber 5 and shortening the service life of the temperature digital display device 7. The sealing gasket 6 has a sealing hole corresponding to the connecting hole 51 and extending into the drinking water port 11. The installation channel 61 in the drinking mouth 11 fits tightly with the installation channel 61, further improving the heat preservation effect of the cup body. The outer wall of the temperature sensor and the drinking mouth digital display device 7 are provided with a temperature sensing probe 74. The temperature sensing probe 74 passes through the connecting hole 51 and the installation channel 61 in sequence and extends into the drinking mouth 11. The temperature sensing probe 74 senses the temperature at the drinking mouth 11 and transmits the temperature signal at the drinking mouth 11 to the temperature digital display device 7. In order to prevent water or water vapor in the cup body from entering the installation chamber 5 through the installation channel 61, the temperature sensing probe 74 is interference fit with the installation channel 61. By arranging the temperature digital display device 7 on the upper cover 2 and separating it from the lock buckle 4, when in use, there is no need to look at the top cover 3 to intuitively know the temperature of the liquid in the cup body, which is more convenient to use. At the same time, the temperature sensing device is separately arranged from the lock buckle 4. Frequent opening of the cup cover will not shorten the service life of the temperature sensing device. Compared with the prior art, the utility model has a long service life and is more convenient to use.

[0031] like Figure 5 As shown, in order to prevent the temperature sensing device from shaking in the installation chamber 5 and colliding with the inner wall of the installation groove, positioning grooves 54 are provided on the inner wall of the installation chamber 5 in the vertical direction to position the four corners of the temperature digital display device 7. The setting of the positioning grooves 54 can prevent the stable sensing device from rotating 360 degrees.

[0032] like Figure 5 and Figure 6As shown, the upper cover 2 has a through hole 21 running from the top to the bottom, and the top cover 3 is located at the through hole 21 for covering the through hole 21, and the side wall of the top cover 3 is provided with an arc-shaped groove 31 distributed along its circumference. The arc-shaped groove 31 can be one or more. When there is one arc-shaped groove 31, the arc length of the arc-shaped groove 31 is greater than or equal to half of the circumference of the inner wall of the through hole 21. When there are multiple arc-shaped grooves 31, the arc-shaped grooves 31 are evenly distributed in a circumferential annular array along the side wall of the top cover 3, and the inner wall of the through hole 21 is provided with an elastic arc-shaped protrusion 22 that matches the arc-shaped groove 31 one by one. The top cover 3 is clamped on the upper cover 2 through the arc-shaped groove 31 and the elastic arc-shaped protrusion 22. This connection method realizes the detachable connection between the top cover 3 and the upper cover 2, which is convenient for assembly. In addition, the top cover 3 can also be connected to the upper cover 2 by threaded fitting.

[0033] Specifically, the bottom of the top cover 3 has a sleeve 32 for sleeve-mounting the mounting bin 5, and the inner wall of the sleeve 32 is provided with an arc-shaped hook groove 321 along its circumference. The arc-shaped hook groove 321 can be one or more. When there is one arc-shaped hook groove 321, the arc length of the arc-shaped hook groove 321 is greater than or equal to half of the circumference of the inner wall of the sleeve 32. When there are multiple arc-shaped hook grooves 321, the arc-shaped hook grooves 321 are evenly distributed in a circumferential annular array along the inner wall of the sleeve 32. An elastic hook body 52 is provided on the outer wall of the mounting bin 5, which cooperates with the arc-shaped hook groove 321 one by one. When the sleeve 32 sleeves the mounting bin 5 inside, the elastic hook body 52 cooperates with the arc-shaped hook groove 321 to fix the mounting bin 5 in the sleeve 32, and the upper end of the temperature digital display device 7 abuts against the top wall of the sleeve 32, which can prevent the temperature sensing device from sliding up and down on the positioning groove 54, thereby further improving the stability of the temperature digital display device 7. The arc-shaped hook groove 321 cooperates with the elastic hook body 52 to achieve a detachable connection between the installation chamber 5 and the top cover 3. This connection method facilitates the installation of the temperature digital display device 7 in the installation chamber 5, is simple and convenient to install, and can save installation costs.

[0034] like Figure 4 As shown, to prevent relative rotation between the mounting chamber 5 and the sleeve 32 and further enhance the stability of the mounting structure of the mounting chamber 5 on the sleeve 32, a vertically arranged positioning block 53 is provided on the outer wall of the mounting chamber 5. The sleeve 32 has a positioning socket 322 corresponding to the positioning block 53. When the sleeve 32 encloses the mounting chamber 5, the positioning block 53 extends into the socket to prevent relative rotation between the top cover 3 and the mounting chamber 5. The lower end of the mounting chamber 5 has an outwardly extending annular step 55. When the mounting chamber 5 is connected to the sleeve 32, the end of the sleeve 32 abuts against the annular step 55, further enhancing the waterproof effect of the mounting chamber 5.

[0035] like Figure 3 and Figure 5As shown, the temperature digital display device 7 includes a circuit board 71, a display screen 72, a power supply 73 and the temperature sensing probe 74. The power supply 73 is connected to the circuit board 71, and the temperature sensing probe 74 and the display screen 72 are integrated on the circuit board 71. The display screen 72 is located between the top cover 3 and the circuit board 71. When the temperature sensing probe 74 senses the temperature signal and transmits the signal to the display screen 72, the display screen 72 displays the temperature of the cup body. The user can read the temperature on the display module through the top cover 3, which is simple and convenient.

[0036] like Figure 7 As shown, the lower cover 1 is provided with a lower lock groove 12 which is open in the direction of the upper cover 2 on the side away from the hinge, and the upper cover 2 is provided with an upper lock groove 23 which is open in the direction of the lower cover 1 at the corresponding position of the lower lock groove 12. When the upper cover 2 is covered on the lower cover 1, the upper lock groove 23 and the lower lock groove 12 are combined to form a runway-shaped lock groove, and the lock buckle 4 is rotatably connected to the lower lock groove 12 through a rotating shaft 414. The lock buckle 4 has a first hook 411, and a second hook 231 which cooperates with the first hook 411 is provided in the upper lock groove 23. A return spring is provided between the lower lock groove 12 and the lock buckle 4, and the return spring is provided below the rotating shaft 414. In order to avoid interference between the first hook 411 and the second hook 231 when the upper cover 2 is covered on the lower cover 1, the first hook 411 has a first guide inclined surface 413. The second hook 231 has a second guide inclined surface 232 that cooperates with the first guide inclined surface 413. When the upper cover 2 is closed on the lower cover 1, the second inclined surface squeezes the first inclined surface, and the lock buckle 4 forms a lever with the rotation point as the fulcrum. The lock buckle 4 above the rotating shaft 414 is squeezed outward and expanded, and the lock buckle 4 below the rotating shaft 414 squeezes the reset spring inward. When the second hook 231 slides along the first inclined surface until it is separated from the first inclined surface, the lock buckle 4 on the upper side of the rotating shaft 414 rebounds under the action of the reset spring, and the first hook 411 hooks on the second hook 231 to lock the upper cover 2 and the lower cover 1; when the upper cover 2 needs to be opened, the lock buckle 4 on the lower side of the rotating shaft 414 is pressed, and the lock buckle 4 on the upper side of the rotating shaft 414 is expanded outward, the first buckle is separated from the second hook 231, and the upper cover 2 is unlocked. At this time, the upper cover 2 can be opened.

[0037] like Figure 8As shown, the lock buckle 4 includes a rotating block 41 and a sliding block 42. The rotating block 41 is rotatably connected to the groove walls on both sides of the lower lock groove 12 through a rotating shaft 414. The first hook 411 is located on the upper side of the rotating block 41. The rotating block 41 is provided with two vertically arranged slide grooves 412. The sliding block 42 has an elastic limiting hook 421 that extends into the two slide grooves 412 and hooks on the bottom wall of the slide groove 412. The elastic limiting hook 421 can slide along the slide groove 412. The sliding block 42 is provided with a limit block 422 that extends into the sliding groove 412. When the first hook 411 is hooked on the second hook 231, the sliding block 42 is slid to make the limit block 422 abut against the lower end of the rotating shaft 414 to limit the rotation of the rotating block 41. When the limit block 422 abuts against the lower end of the rotating shaft 414, the limit block 422 limits the rotation of the rotating block 41, which can avoid the accidental opening of the upper cover 2, causing the drink in the cup body to overflow, and avoid the risk of scalding caused by accidental operation.

[0038] like Figure 7 As shown, a blocking platform 121 is provided in the lower locking groove 12. When the sliding block 42 slides downward until the lower end of the elastic limiting hook 421 abuts against the blocking platform 121, the limiting block 422 disengages from the rotating shaft 414, releasing the restriction on the rotating block 41. The provision of the blocking platform 121 limits the sliding range of the sliding block 42, allowing the sliding block 42 to be quickly and accurately limited.

[0039] like Figure 8 As shown, the rotating block 41 is provided with a first limiting groove 415 and a second limiting groove 416, and the sliding block 42 is provided with a limiting strip 423 that cooperates with the first limiting groove 415 and the second limiting groove 416. When the sliding block 42 slides until the limiting block 422 abuts against the lower end of the rotating shaft 414, the limiting strip 423 is located in the first limiting groove 415. When the sliding block 42 slides downward until the lower end of the elastic limiting hook 421 abuts against the blocking platform 121, the limiting strip 423 is located in the second limiting groove.
