[0023] Figure 7 This is a schematic diagram of the overall structure of the cooling and heating cup in one embodiment of the present invention. Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] See Figures 1-7This cooling and heating cup includes an outer cup 1, an inner cup 2, and a lid assembly. The lid assembly is detachably connected to both the outer cup 1 and the inner cup 2. The lid assembly is equipped with a heating element 3 for heating the inner cup 2. The heating element 3 is located at the mouth of the inner cup 2, allowing heat generated by the heating element 3 to enter the liquid storage chamber 5 of the inner cup 2 through the mouth, thereby heating the liquid in the storage chamber 5. The outer cup 1 contains a middle liner 4 for storing phase change materials. When the inner cup 2 is heated, the outer cup 1 and the lid assembly are detached, allowing the middle liner 4 to be removed to prevent it from interfering with the heating process. During cooling, the outer cup 1 is connected to the lid assembly, and the middle liner 4 is wrapped around the outside of the inner cup 2. The phase change material of the middle liner 4 conducts the cooling effect to the liquid storage chamber 5 through the body of the inner cup 2, thereby cooling the liquid in the liquid storage chamber 5. At this time, the heating element 3 does not work. The middle liner 4 can be placed in the refrigerator for refrigeration so that the phase change material inside the middle liner 4 freezes, thereby maintaining its cooling effect. The middle liner 4 can be used directly in the outer cup 1, or it can be taken directly out of the outer cup 1 and placed in the refrigerator for refrigeration. The heating element 3 is used to heat the water or milk in the liquid storage chamber 5, etc.; the middle liner 4 is used to cool the water or beverages in the liquid storage chamber 5, etc.

[0026] The inner cup 2 is provided with a liquid storage chamber 5. When the outer cup 1 is connected to the cup lid assembly, the inner cup 2 is located inside the outer cup 1, thus protecting the inner cup 2. When the inner cup 2 is heated, the cooling and heating cup is placed upside down and supported on the support by the cup lid assembly. When the inner cup 2 is cooled, the cooling and heating cup is placed upright and supported on the support by the outer cup 1. When the cooling and heating cup is placed upside down, the heating element 3 is located below the inner cup 2. The liquid in the liquid storage chamber 5 will flow downward under the action of gravity. The liquid at the bottom will flow to the mouth of the inner cup 2 and thus come into contact with the heating element 3, improving the heating efficiency.

[0027] The cup lid assembly is equipped with a temperature probe 6 for detecting the temperature of the liquid in the storage chamber 5. The temperature probe 6 is mounted on the heating element 3. The cup lid assembly also contains a control board 7, which is electrically connected to the heating element 3 and the temperature probe 6. The control board 7 controls the heating power of the heating element 3 based on the temperature detected by the temperature probe 6. When the temperature probe 6 detects a low liquid temperature, the control board 7 controls the heating element 3 to increase its heating power. When the temperature probe 6 detects a high liquid temperature, the control board 7 controls the heating element 3 to decrease its heating power. When the temperature probe 6 detects that the liquid temperature has reached a set value, the control board 7 controls the heating element 3 to stop working.

[0028] A tilt switch (not shown in the figure) is provided on the control board 7, or a tilt switch is provided inside the cup lid assembly. The control board 7 is electrically connected to the tilt switch. When the refrigeration / heating cup is placed upright, the tilt switch is turned off to disconnect the power supply, so that the control board 7 cannot control the heating element 3 to heat the inner cup 2. When the refrigeration / heating cup is placed upside down, the tilt switch is turned on to connect the power supply. At this time, the control board 7 can control the heating element 3 to heat the inner cup 2. The working principle of the tilt switch is existing technology and will not be described in detail here.

[0029] The cup lid assembly contains a power supply module 8 and a charging board 9. The power supply module 8 is a battery. The control board 7 is electrically connected to the power supply module 8 and the charging board 9 respectively. The charging board 9 is provided with a charging interface 10 for connecting to an external charging terminal to charge the battery. The power supply module 8 can supply power to all electrical components of the cooling and heating cup, so that the cooling and heating cup can cool and heat without being plugged in, making it convenient for outdoor use.

[0030] The charging port 10 is located on the side of the cup lid assembly (outer cup fixing seat 13). The side of the cup lid assembly (outer cup fixing seat 13) is provided with a clearance hole 33, which facilitates the connection of the charging connector to the charging port 10.

[0031] The outer cup 1 includes an integrally formed outer cup shell 11 and an inner cup shell 12, with a gap 32 between the outer cup shell 11 and the inner cup shell 12. The middle liner 4 is disposed inside the inner cup shell 12. The gap 32 can block the middle liner 4 from conducting the cooling effect outward, so that the middle liner 4 conducts the cooling effect mainly inward, thereby improving the cooling efficiency of the inner cup 2.

[0032] The cup lid assembly includes an outer cup fixing seat 13 and an inner cup fixing seat 14. The outer cup 1 is detachably connected to the outer cup fixing seat 13, and the inner cup 2 is detachably connected to the inner cup fixing seat 14. The inner cup fixing seat 14 is located at the bottom of the outer cup fixing seat 13.

The positioning edge 16 is pressed between the first sealing element 15 and the bottom wall of the positioning groove 17 so that the inner cup fixing seat 14 is fixed on the outer cup fixing seat 13.

[0033] The outer cup 1 has an upwardly extending first extension edge 18 at its mouth, and the outer cup fixing seat 13 has a downwardly extending second extension edge 19 at its bottom. The first extension edge 18 has a first external thread 20, and the second extension edge 19 has a first internal thread 21. The first external thread 20 and the first internal thread 21 are connected to connect the outer cup fixing seat 13 and the outer cup 1. The first extension edge 18 abuts against the first sealing member 15, which is located between the first extension edge 18 and the second extension edge 19. The first sealing member 15 can seal the gap between the first extension edge 18 and the second extension edge 19, preventing the middle liner 4 from leaking cold to the outside through the gap when it is cooling, thereby improving the cooling efficiency.

[0034] The inner cup 2 has an upwardly extending third extension edge 22 at its mouth, and the inner cup fixing seat 14 has a downwardly extending fourth extension edge 23 at its bottom. The third extension edge 22 has a second external thread 24, and the fourth extension edge 23 has a second internal thread 25. The second external thread 24 and the second internal thread 25 are connected to connect the inner cup fixing seat 14 and the inner cup 2. A second sealing element 26 is provided between the third extension edge 22, the fourth extension edge 23 and the outer cup fixing seat 13. The second sealing element 26 can seal the gap between the third extension edge 22, the fourth extension edge 23 and the outer cup fixing seat 13 to prevent heat from leaking to the outside through the gap when the heating element 3 is heating, thereby improving the heating efficiency. The second sealing element 26 is a sealing ring.

[0035] The inner side of the second sealing member 26 is provided with a positioning slot 27, and the outer edge of the heating element 3 is provided with a positioning insert 28. The positioning insert 28 is inserted into the positioning slot 27 so that the heating element 3 is positioned on the cup lid assembly, and the heating element 3 is fixed to the bottom of the outer cup fixing seat 13 by screws; the heating element 3 is a thick film heater, which has a fast heating speed and high thermal efficiency.
