[0002] Chinese people like to drink hot water, while Westerners like to drink cold water. People's requirements for the temperature of beverages are becoming increasingly diverse. However, it is not easy to enjoy ice cola, hot coffee, and warm water instantly during outdoor adventures, self-driving trips, and long-term travel. Existing refrigeration and heating devices are either bulky and inconvenient to carry, making it difficult to meet people's needs for use on the move; or they rely on external power supplies and cannot function in environments where there is no power interface. Although there are some small refrigeration products on the market, these products generally have poor compatibility with common bottled beverages, making it impossible for people to easily realize the cooling and heating of beverages in different scenarios. This situation not only brings inconvenience to people's lives, but also limits the expansion of beverage consumption scenarios.

[0006] At present, there is still a lack of a portable intelligent temperature control device that can operate independently after charging and can cool, heat and keep bottled liquids warm. The bottled liquid intelligent temperature control device and operation method of the present invention are intended to cool and heat beverages at any time, regulate the temperature of beverages, and meet people's various needs. Summary of the invention

[0007] The present invention aims to overcome the difficulties of the prior art and introduce a portable intelligent refrigeration and heating bottled water temperature control device based on semiconductor refrigeration and heating technology. The device is compact and portable and can heat and cool bottled drinks at any time in various scenarios. By adopting rechargeable batteries for power supply, it gets rid of the constraints of power supply, greatly improves the convenience of use, and effectively solves the dilemma of people's difficulty in conveniently cooling and heating bottled drinks in external environments.

[0008] The intelligent device is mainly composed of a cooling and heating module, a battery module, a charging module, a digital display module and a device body, including a replaceable threaded lining module 10, a battery module 20, a support module 30, a charging module 40, an insulation module 50, a cooling and heating module 60, a heat dissipation module 70, a fan module 80, a hot and cold selection module, a digital display module, a temperature control module, an electronic control module, and an algorithm module. Each module has a clear division of labor and works closely together to ensure the safe, efficient, and intelligent operation of the cooling and heating device.

[0009] In the above modules, the lining is a replaceable accessory, and its lining size and structure meet the requirements of bottles of different calibers; the support module includes the outer shell and its connected internal support structure to meet the requirements of device integration; the cooling and heating module is composed of N and P semiconductors, which form an integrated layered integrated structure. The semiconductors are bonded to the alumina ceramic substrate or aluminum nitride ceramic substrate by welding. The upper and lower ceramic substrates are the front and back of the cooling and heating module respectively. The number of cooling and heating modules in each intelligent device is 1 to 4. When it is greater than 1, the thickness of a single cooling and heating module is consistent, and the shape is semicircular or fan-shaped. They are all closely arranged in a plane and put together to form a circular integrated module.

[0010] In the smart device, the front side of the cooling and heating module, i.e. the working surface, is visible, and the working surface area can be adjusted by replacing the threaded liner. When the device is tightened with the bottle, the bottle is stood up so that the liquid surface in the bottle is in direct contact with the working surface of the cooling and heating module in the device. When the drink needs to be heated, the liquid near the working surface heats up first, and because the density of hot water is low, it diffuses upward, so that the liquid in the bottle has a uniform temperature; when the drink needs to be cooled, the liquid near the working surface cools down first, and after ice crystals are formed, they float upward because the density of ice is lower than that of water, so that the liquid in the bottle has a uniform temperature until the whole is frozen.

[0011] In a cooling-only smart device, the back of the cooling module is the heat dissipation surface, which is opposite to the fan inside the device. When working, the front temperature of the cooling module is low, and the back temperature rises greatly. The fan is used to force the back to dissipate heat, and the flowing air takes away the heat from the back and escapes through the heat dissipation structure to cool the back.

[0012] In a smart device that only heats, when working, the front temperature of the heating module is high and the back temperature is low, and no heat dissipation structure design is performed.

[0013] In the intelligent device, the side of the cooling and heating module tightly surrounds the overall insulation module. The insulation module is an integral structure of an aerogel insulation composite material, has no splicing gaps, a thickness of 3 to 20 mm, which is consistent with the thickness of the cooling and heating module, and a thermal conductivity of 0.015 to 0.023 W / mK. Preferably, melamine foam reinforced barium aluminum silica aerogel composite material, melamine foam reinforced lithium aluminum silica aerogel composite material, melamine foam reinforced silica aerogel composite material, and ultrafine glass fiber reinforced silica aerogel composite material are selected. The barium aluminum silica aerogel is a composite oxide aerogel of barium oxide-aluminum oxide-silicon oxide, and the lithium aluminum silica aerogel is a composite oxide aerogel of lithium oxide-aluminum oxide-silicon oxide.

[0014] In the smart device, the cooling and heating module is circular, and its outer diameter is 2 to 5 mm smaller than the inner diameter of the battery module inner hole; the front of the cooling and heating module is covered with high thermal conductivity stainless steel foil, preferably 304 stainless steel, with a thickness of 0.2 to 2 mm and a diameter of 2 to 5 mm larger than the inner diameter of the battery module inner hole.

[0015] In the intelligent device, the replaceable thread liner is made of high and low temperature resistant food grade plastic, preferably polypropylene and high density polyethylene, with a water repellency greater than 98%.

[0016] In the intelligent device, the replaceable threaded liner is an accessory, the wall thickness of which is 3 to 10 mm, the height of which is 20 to 40 mm, and the inner side of which has threads that match the threads and sizes of the paired beverage bottle mouth.

[0017] In the smart device, the replaceable threaded liner is tightly embedded in the inner hole of the battery module, the bottom is tightly connected to the stainless steel metal foil on the surface of the cooling and heating module, the top is 5 to 15 mm higher than the battery module, and the outer diameter of the protruding part is 5 to 20 mm larger than the embedded part.

[0018] In the refrigeration and constant temperature functional device, the heat dissipation module includes a heat dissipation support structure, a porous heat dissipation grille and a fan, and is equipped with a small fan with a speed of 2000-5000 rpm. The fan runs continuously to accelerate the air circulation around the heat sink, effectively improve the heat dissipation efficiency, and thus ensure the stable cooling performance of the refrigeration plate.

[0019] In the smart device, the battery module uses lithium batteries as power sources, multi-protocol bidirectional super fast charging, built-in 10000~20000mAh capacity batteries, equipped with Type-C interface, charging power can reach 16-26W, and supports 5V / 2A fast charging specifications. The charging interface is set on the side of the device and is equipped with a waterproof protective cover, which can effectively block liquid intrusion, avoid short circuits and other faults caused by water ingress, and ensure the safety and stability of the charging process.

[0020] In the smart device, the main body of the device is square and circular. When it is square, the side length of the square is 50-200mm and the thickness is 30mm-100mm; when it is circular, the outer diameter is 50-100mm and the thickness is 30-100mm.

[0021] Beneficial Effects

[0022] (1) Excellent portability. The small size makes the cooling and heating device easy to store. Whether it is placed in a small pocket of a backpack or in a pocket of clothing, it will not take up too much space, perfectly meeting people's carrying needs in mobile scenarios such as outdoor adventures and travel.

[0023] (2) Wide versatility: The device size and thread specifications are precisely matched to those of common bottled beverages, making this cooling and heating device suitable for the vast majority of bottled beverages on the market, whether it is a mineral water bottle, a cola bottle or a juice bottle.

[0024] (3) Energy-saving and efficient operation: The organic combination of semiconductor refrigeration and heating device technology with cooling fans and insulation layers not only achieves efficient cooling, but also effectively reduces energy consumption, extends battery life, and reduces users' dependence on power.

[0029] Embodiment 1: Intelligent temperature control device and operation method for heating bottled liquid only

[0030] The main body of the device adopts a square design with a side length of 100mm and a thickness of 50mm. The battery module uses a built-in 15000mAh capacity lithium battery, equipped with a Type-C interface, set on the side of the device and with a waterproof protective cover. The replaceable threaded liner is high and low temperature resistant food-grade polypropylene, 5mm thick, the inner thread and diameter match the common mineral water bottle mouth, tightly embedded in the inner hole of the battery module, and the bottom is tightly docked with the 304 stainless steel metal foil (thickness 0.5mm) on the working surface of the heating module, and the top is 10mm higher than the battery module. The heating module is circular, with an outer diameter smaller than the inner diameter of the battery module and a spacing of 3mm. The front is covered with metal foil, there is no heat dissipation structure on the back, and the side is surrounded by 20mm thick melamine foam reinforced barium aluminum silicon aerogel composite material.

[0031] Performance: The battery module of the device supports multi-protocol bidirectional super-fast charging, with a charging power of up to 20W and supports 5V / 2A fast charging specifications. When heating is needed, tighten the device and the bottle and stand it upright. The liquid surface in the bottle contacts the working surface of the heating module in the device. The liquid close to the working surface heats up first. The principle of low density of hot water diffusing upward is used to make the liquid in the bottle heat up evenly. When the room temperature is 20℃, 500ml of mineral water can be heated to 50℃ in 5 minutes.

[0032] Example 2: Intelligent temperature control device and operation method for cooling bottled liquid only

[0033] The main body of the device is round, with a diameter of 80mm and a thickness of 60mm. The battery module has a built-in 18000mAh lithium battery and is also equipped with a Type-C interface with a waterproof protective cover on the side of the device. The replaceable threaded liner is made of high-density polyethylene with a thickness of 6mm, and its inner thread and size are adapted to carbon dioxide beverage bottles. The side of the refrigeration module is surrounded by a 10mm thick ultra-fine glass fiber reinforced silica aerogel composite material, and the back is opposite to a small fan with a speed of 3000 rpm. The fan runs continuously to accelerate the air circulation around the heat sink.

[0034] Performance: The battery module can be charged at up to 22W and supports 5V / 2A fast charging. During refrigeration, the liquid near the working surface in the bottle first cools to form ice crystals. Since the density of ice crystals is less than that of water, they float upward, cooling the hot water on the top and the liquid in the bottle until the whole is frozen. When the temperature rises greatly on the back of the refrigeration module, the fan is used for forced heat dissipation, and the flowing air takes away the heat and escapes through the heat dissipation structure, ensuring the stable refrigeration performance of the refrigeration sheet. At room temperature of 30°C, the beverage in a 250ml Coke bottle can be cooled to 0°C within 2 minutes.

[0035] Example 3: Intelligent temperature control device and operation method for maintaining constant temperature of bottled liquid

[0036] The main body of the device adopts a circular design with a diameter of 70mm and a thickness of 40mm. The battery module uses a built-in 12000mAh capacity lithium battery, and the Type-C interface is set on the side of the device and equipped with a waterproof protective cover. The replaceable threaded liner is made of high and low temperature resistant food-grade plastic, composed of polypropylene and high-density polyethylene, with a thickness of 8mm, and its inner thread and size are suitable for tea drinks. The liner is tightly embedded in the inner hole of the battery module, and the bottom is tightly fitted with the 0.8mm thick 304 stainless steel foil on the surface of the cooling and heating dual modules, and the top is 8mm higher than the battery module. The device includes two independent semicircular cooling and heating modules, and the two modules are connected in parallel to form a circular cooling and heating device assembly module, one is a semicircular cooling module for cooling drinks; the other is a semicircular heating module for heating drinks. The algorithm module controls the control module, and the two semicircular modules are controlled to work alternately according to the requirements of the temperature control module, and alternately cool and heat, so as to keep the temperature of the drink constant. The side of the cooling and heating assembly module is surrounded by a 15mm thick melamine foam reinforced lithium aluminum silicon aerogel composite material. Inside the smart device, a high-precision intelligent temperature control system and a small fan with a speed of 2500 rpm are installed on the back of the cooling and heating modules. When the temperature on the back is higher than 25°C, the fan starts to cool down.

[0037] Performance: If the temperature of the liquid in the bottle is higher than the set temperature, the temperature control system immediately starts the cooling module, and the liquid near the working surface of the module is cooled first, and the liquid is cooled evenly through heat exchange; when the liquid temperature is lower than the set temperature, the heating module starts to work, and the liquid near the working surface of this area is heated first, and the liquid is heated evenly by heat transfer. During the entire constant temperature process, the temperature control system accurately controls and intelligently controls the two groups of cooling and heating modules to work intermittently or simultaneously based on real-time temperature data, ensuring that the liquid in the bottle always maintains the set constant temperature state. When the temperature on the back of the cooling and heating module changes, the fan will automatically adjust the speed to dissipate heat or assist heat conduction, fully ensuring the stable operation of the constant temperature function.

[0038] Example 4: Intelligent temperature control device and operation method for cooling, heating and maintaining constant temperature of bottled liquid

[0039] The main body of the device adopts a square design with a side length of 80mm and a thickness of 45mm. The battery module uses a built-in 15000mAh capacity lithium battery. The Type-C interface is set on the side of the device and is equipped with a waterproof protective cover, which can effectively prevent liquid intrusion and ensure charging safety. The replaceable threaded liner is made of high and low temperature resistant food-grade polypropylene and high-density polyethylene composite materials with a thickness of 7mm. The inner thread and size are perfectly matched with the mouth of a common pure water bottle. The liner is tightly embedded in the inner hole of the battery module, and the bottom is tightly fitted with the 1mm thick 304 stainless steel metal foil on the surface of the cooling and heating module, and the top is 10mm higher than the battery module.

[0040] The cooling and heating module is composed of closely arranged N-type and P-type semiconductors, with the upper layer being N-type and the lower layer being P-type. The overall shape is circular, with an outer diameter smaller than the inner diameter of the battery module and a spacing of 3mm. The front of the cooling and heating module is covered with metal foil, and the sides are tightly surrounded by a 15mm thick melamine foam-reinforced silica aerogel composite material. The thickness of the composite material is consistent with the thickness of the cooling and heating module, and the upper and lower surfaces remain flush, effectively reducing heat loss. Inside the device, the back of the cooling and heating module corresponds to a silent small fan with a speed of 3000 rpm, which is used for efficient heat dissipation and heat conduction assistance. There are three membrane button lights on the outer surface of the device: cooling, heating and constant temperature: when the cooling light is pressed, the DC current enters from the N terminal and exits from the P terminal, and the fan starts to cool the pure water; when the heating light is pressed, the DC current enters from the P terminal and exits from the N terminal, the fan does not start, and the pure water is heated; when the constant temperature light is pressed, you can select the required constant temperature, and then click the start button, the algorithm module and the electronic control module in the intelligent device start, control the DC current to automatically switch between the N and P terminals, and the fan starts.

[0041] Performance: The battery module supports multi-protocol bidirectional super-fast charging, with a charging power of up to 20W, and supports 5V / 2A fast charging specifications. When the user starts the device function, the target temperature can be set through the intelligent temperature control system. During the whole process, the temperature control chip accurately controls the current direction and the working status of the cooling and heating module through the electronic control module according to the real-time temperature data to achieve efficient heat exchange. When the temperature on the back of the cooling and heating module changes, the fan automatically adjusts the speed to ensure the stable operation of the module and avoid performance affected by overheating or overcooling.
