Technical Field
[0001] This utility model relates to the field of thermos cup technology, specifically to a thermos cup that can display temperature. Background Technology
[0002] A smart temperature-controlled cup is a daily drinking appliance that integrates cooling and heating functions, designed to provide users with an instant cold or hot beverage experience, enhancing the convenience and comfort of drinking. It typically employs semiconductor thermoelectric technology (Peltier effect) as the core of its temperature control.
[0003] However, current products have some obvious problems in design and use: First, the stirring device introduced to achieve uniform heat conduction of the liquid inside the cup mostly adopts a traditional structure design where the mechanical shaft driven by a motor penetrates the cup wall. This not only poses a potential risk of water leakage and a serious challenge to the sealing of the cup, but also creates hard-to-clean hygiene dead spots inside the stirring components, which can easily breed bacteria after long-term use and affect the user's health.
[0004] Meanwhile, semiconductor thermoelectric cooling modules generate a large amount of waste heat at their hot end during operation. Insufficient heat dissipation efficiency will directly lead to a sharp decline in cooling / heating performance. Many products sacrifice the performance of the heat dissipation system in pursuit of a compact size, using only simple air cooling, which results in unstable temperature control during continuous operation and may even shorten the service life due to overheating.
[0005] In summary, a thermos cup that can display temperature needs to be developed to solve the above problems. Utility Model Content
[0006] To address the shortcomings of existing technologies, the technical solution adopted by this utility model is: a thermos cup that can display temperature, specifically comprising: a cup body, a cup lid, and a cup bottom, wherein a working mechanism is sleeved on the outer surface of the cup body, and the working mechanism further comprises:
[0007] A magnetic stirring component is disposed inside the cup body, and the magnetic stirring component includes a magnetic rotor;
[0008] The display component is slidably connected to the outer surface of the cup body, and the display component includes an annular housing.
[0009] A heat dissipation component, mounted on the lower surface of the display component, includes a housing. The cup body employs a double-layer vacuum 304 stainless steel structure, with a vacuum between the inner liner and the outer wall to isolate heat exchange and achieve efficient heat preservation. This structure achieves lightweighting while maintaining strength. The cup bottom has a single-layer structure made of lightweight aluminum alloy with excellent thermal conductivity; this aims to reduce weight while ensuring efficient heat transfer to the interior of the cup.
[0010] Furthermore, the magnetic rotor is detachably and fixedly connected to the stirring fan blade with an embedded permanent magnet by magnetic adsorption. A turbine guide shroud is rotatably connected to the outer surface of the magnetic rotor. A first magnetic block is installed on the inner wall of the turbine guide shroud. A second magnetic block is magnetically adsorbed onto the first magnetic block. A sealing rubber ring is provided below the second magnetic block. The magnetic rotor is the core driving component, with a high-performance neodymium iron boron permanent magnet embedded inside, making it a powerful magnet in itself. Its outer surface is made of food-grade stainless steel and sealed to prevent contact with the liquid, thus preventing corrosion and contamination. Its function is to form a magnetic coupling with the driving magnet below, transmitting torque to the cup without contact. The stirring blades are made of lightweight food-grade PP material, with a turbine-shaped design to optimize fluid dynamics and efficiently agitate the liquid. A neodymium iron boron magnet is embedded in its inner surface, facilitating direct attraction between the blades and the strong magnetic field of the magnetic rotor itself. When the magnetic rotor rotates, the magnetic attraction drives the stirring blades to rotate synchronously. It also allows for quick disassembly and assembly without tools, facilitating cleaning. The turbine guide is made of lightweight food-grade PP plastic and has internal guide ribs. Its function is to remain stationary, guiding the direction of liquid flow generated by the agitation of the fan blades, creating intense turbulence, breaking down temperature stratification, and greatly improving heat exchange efficiency, while also providing safety protection. Its structure is intentionally designed as a dome with a raised central area and gradually decreasing periphery, serving multiple functions: this shape matches the rotating agitator blades, more efficiently guiding the fluid thrown out by the centrifugal force of the blades; the raised central structure provides ample rotation space for the magnetic rotor and agitator blades below, ensuring that the rotating components do not interfere with or rub against the turbine guide shield; both the first and second magnetic blocks are ring magnets, using high-temperature neodymium iron boron magnets, which have strong attraction and high temperature resistance. The ring design provides uniform and concentrated magnetic attraction, ensuring the turbine guide shield is stable while being less forceful than that applied by an ordinary hand, allowing users to remove the turbine guide shield and other parts from the cup without tools during subsequent cleaning.
[0011] Furthermore, a gap is provided between the bottom of the stirring blade and the upper surface of the cup bottom. This gap is configured to ensure that the stirring blade does not rub against the cup bottom when it rotates. This gap ensures that the bottom of the stirring blade does not rub against the upper surface of the cup bottom when it rotates, while effectively agitating the fluid in the cup bottom area and avoiding the formation of dead zones.
[0012] Furthermore, the turbine guide shield is detachably fixed to the inner surface of the cup body, the second magnetic block is installed on the inner wall of the cup body, and the sealing rubber ring is embedded in the annular groove on the lower surface of the cup bottom. The sealing rubber ring provides stability and high-temperature resistance, and also cushions and absorbs shocks for the cup bottom, making the product more stable when placed.
[0013] Furthermore, an LCD screen is installed on the inner wall of the annular shell, and a charging plug is arranged opposite to the LCD screen inside the annular shell. The charging plug is electrically connected to a power management module via wires, and the power management module is connected to a backup battery module via wires. The annular shell, as the main structural component of the display unit, is made of lightweight alloy plastic injection molding, ensuring structural strength while reducing weight. The LCD screen is a small, ultra-low-power OLED display used to display the estimated temperature of the liquid inside the cup monitored by a patch-type temperature sensor in real time. The power management module is a highly integrated PCB board, which integrates an MCU microprocessor, voltage conversion circuit, charging management chip, and temperature processing algorithm, and its function is to intelligently manage power distribution.
[0014] Furthermore, the inner surface of the annular shell is slidably connected to the outer surface of the cup body, and the power management module is electrically connected to the liquid crystal display screen via wires.
[0015] Furthermore, the power management module and the backup battery module are both installed inside the annular housing. The backup battery module uses a thin and lightweight lithium polymer pouch battery with a capacity sufficient to allow the display and control circuitry to operate independently for at least two hours, aiming to provide battery life for short-term mobile use.
[0016] Furthermore, a control circuit board is installed on the inner wall of the outer shell, and ventilation grilles are provided on the outer surface of the outer shell. A heat transfer plate is located at the center of the top of the outer shell, and a surface-mount temperature sensor is installed at the center of the upper surface of the heat transfer plate. The control circuit board integrates a motor drive circuit, a communication module, etc., and is responsible for receiving instructions from the main control board to precisely control the start, stop, and speed of the motor. The outer shell is made of lightweight ABS plastic, and a large number of ventilation grilles are provided on the outer surface for air circulation. The heat transfer plate is made of lightweight, high thermal conductivity T2 copper plate, with its upper part in close contact with the bottom of the cup and its lower part in contact with the cold end of the thermoelectric cooling module. Its function is to efficiently transfer the cold / heat generated by the thermoelectric cooling module to the bottom of the cup. The surface-mount temperature sensor is tightly attached to the upper surface of the heat transfer plate with thermally conductive silicone grease. Its function is to indirectly and quickly monitor the temperature of the bottom of the cup and transmit the data to the control circuit board, which then processes the data and converts it into a display temperature.
[0017] Furthermore, a thermoelectric cooling module is attached to the lower surface of the heat transfer plate, and a heat sink is disposed below the thermoelectric cooling module. A driving magnet is rotatably connected to the center of the thermoelectric cooling module. The driving magnet, similar to the magnetic rotor inside the cup, is a multi-pole magnetized neodymium iron boron permanent magnet, which is coupled to the magnetic rotor inside the cup in a vacuum to provide rotational torque. The thermoelectric cooling module, also known as the Peltier effect module, has a lightweight ceramic substrate and is the core actuator for achieving active cooling / heating. The heat sink is a lightweight aluminum alloy heat sink made by aluminum extrusion process, and its function is to absorb the large amount of heat generated by the hot end of the thermoelectric cooling module.
[0018] Furthermore, the lower surface of the drive magnet is equipped with the output shaft of the drive motor, a cooling fan is located below the drive motor, a support plate is installed at the bottom of the cooling fan, and a heat dissipation copper pipe is embedded in the inner wall of the heat sink. The drive motor is a miniaturized and lightweight micro brushless DC motor, whose function is to drive the drive magnet of the output shaft to rotate; the cooling fan is a thin brushless DC fan, whose function is to generate forced airflow, blow it across the heat sink, realize convective heat transfer, and quickly dissipate heat into the environment; the heat dissipation copper pipe is a thin-walled pure copper capillary tube filled with coolant, which is embedded in the fins of the heat sink. Utilizing the extremely high thermal conductivity of the liquid phase change cycle, it assists in quickly diffusing heat from the hot end of the thermoelectric cooling module to the entire heat sink, thereby achieving a composite high-efficiency heat dissipation of "liquid cooling + air cooling".
[0019] Furthermore, the patch-type temperature sensor is located directly below the bottom of the cup, the outer surface of the drive motor is fixed to the center of the heat sink, and the bottom of the support plate is fixed to the bottom of the inner wall of the outer shell.
[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0021] 1. This invention utilizes a drive magnet, a magnetic rotor, and magnetically adsorbable stirring blades in a magnetically rotating stirring component to create a non-contact magnetic coupling stirring system. This system achieves contactless power transmission from the base to the cup, solving the leakage problem that may occur when the mechanical rotating shaft of traditional stirring devices penetrates the cup wall. Simultaneously, the magnetic connection between the stirring blades and the magnetic rotor, as well as the magnetic fixation between the turbine guide and the cup body, allows the entire stirring assembly to be quickly removed without tools, further solving the problem of dirt accumulation and difficult-to-clean hygiene dead spots caused by the blades being placed inside the cup bottom for extended periods.
[0022] 2. This invention utilizes a combination of a heat sink, embedded copper heat pipes, and a cooling fan in its heat dissipation components to create a "liquid cooling + air cooling" composite heat dissipation system. This system directly addresses the problem of the large amount of waste heat generated at the hot end of the thermoelectric cooling module during operation, which can easily lead to performance degradation or even burnout due to overheating. The copper heat pipes utilize phase change to rapidly dissipate the locally high heat flux density heat from the hot end and efficiently diffuse it to the entire air-cooled heat sink, finally being dissipated by forced convection from the fan. This design solves the problem of insufficient heat dissipation capacity during device operation under the premise of miniaturization and lightweight design, ensuring continuous and stable cooling / heating performance and extending the service life of the thermoelectric cooling module and the entire unit.
[0023] 3. This utility model, through the cooperation of a power management module, a surface-mount temperature sensor, and a backup battery module in the display component, constitutes a power backup and temperature control display system. Firstly, the system indirectly and rapidly monitors and displays the liquid temperature in real time via a surface-mount temperature sensor attached to a heat transfer plate, solving the problem of users not knowing the real-time water temperature in the cup and being easily scalded or having their teeth chilled. Secondly, the power management module manages power distribution: when plugged in, it operates at full power and charges the backup battery module; when unplugged, it automatically switches to the backup battery module for power and shuts down the high-power thermoelectric cooling module, maintaining only stirring and display, further solving the problem of the product completely failing when disconnected from a fixed power source, providing practical off-power stirring and temperature display functions.

At the same time, the ring design provides uniform and concentrated magnetic attraction force, ensuring that the turbine guide shroud 313 is stable, while being less than the pulling force applied by an ordinary hand, so that users can remove the turbine guide shroud 313 and other parts from the cup without tools during subsequent cleaning.
[0042] A gap is provided between the bottom of the stirring blade 312 and the upper surface of the cup bottom 4. The gap is configured to ensure that the stirring blade 312 does not rub against the cup bottom 4 when it rotates. This gap ensures that the bottom of the stirring blade 312 does not rub against the upper surface of the cup bottom 4 when it rotates, while effectively agitating the fluid in the area of the cup bottom 4 and avoiding the formation of dead zones.

[0044] An LCD screen 322 is mounted on the inner wall of the annular housing 321. A charging plug 323 is arranged opposite to the LCD screen 322 inside the annular housing 321. The charging plug 323 is electrically connected to a power management module 324 via wires. The power management module 324 is connected to a backup battery module 325 via wires. The annular housing 321, as the main structural component of the display component 32, is made of lightweight alloy plastic injection molding, ensuring structural strength while reducing weight. The LCD screen 322 is a small, ultra-low-power OLED display used to display the estimated temperature of the liquid inside the cup monitored in real time by a surface-mount temperature sensor 335. The power management module 324 is a highly integrated PCB board, integrating an MCU microprocessor, voltage conversion circuit, charging management chip, and temperature processing algorithm, its function being intelligent management of power distribution.
[0045] The inner surface of the annular shell 321 is slidably connected to the outer surface of the cup body 1, and the power management module 324 is electrically connected to the liquid crystal display screen 322 through wires.
[0046] The power management module 324 is installed inside the annular housing 321, and the backup battery module 325 is installed inside the annular housing 321. The backup battery module 325 uses a thin and light lithium polymer pouch battery with a capacity designed to provide battery life for short-term mobile use, ensuring that the display and control circuits can operate independently for at least 2 hours.
[0047] A control circuit board 332 is installed on the inner wall of the housing 331, a ventilation grille 333 is provided on the outer surface of the housing 331, a heat transfer plate 334 is provided at the center of the top of the housing 331, and a patch temperature sensor 335 is installed at the center of the upper surface of the heat transfer plate 334.

The outer shell 331 is made of lightweight ABS plastic, and a large number of ventilation grilles 333 are opened on the outer surface for air circulation.

Its upper part is in close contact with the bottom of the cup 4, and its lower part is attached to the cold end of the thermoelectric cooling module 336. Its function is to efficiently transfer the cold / heat generated by the thermoelectric cooling module 336 to the bottom of the cup 4. The surface-mount temperature sensor 335 is tightly attached to the upper surface of the heat transfer plate 334 with thermally conductive silicone grease. Its function is to indirectly and quickly monitor the temperature of the bottom of the cup 4 and transmit the data to the control circuit board 332, which is then processed by the algorithm and converted into the displayed temperature.
[0048] A thermoelectric cooling module 336 is attached to the lower surface of the heat transfer plate 334. A heat sink 337 is disposed below the thermoelectric cooling module 336. A drive magnet 338 is rotatably connected to the center of the thermoelectric cooling module 336.

[0049] The output shaft of the drive motor 3381 is mounted on the lower surface of the drive magnet 338. A cooling fan 3382 is located below the drive motor 3381, and a support plate 339 is mounted on the bottom of the cooling fan 3382. A heat dissipation copper pipe 3371 is embedded in the inner wall of the heat sink 337. The drive motor 3381 is a miniaturized and lightweight micro brushless DC motor, which drives the drive magnet 338 on the output shaft to rotate. The cooling fan 3382 is a thin brushless DC fan, which generates forced airflow to blow over the fins of the heat sink 337, realizing convective heat transfer and quickly dissipating heat into the environment. The heat dissipation copper pipe 3371 is a thin-walled pure copper capillary filled with coolant. It is embedded in the fins of the heat sink 337 and utilizes the extremely high heat conduction efficiency of liquid phase change cycle to help quickly diffuse heat from the hot end of the thermoelectric cooling module 336 to the entire heat sink 337, thereby achieving a composite high-efficiency heat dissipation of "liquid cooling + air cooling".
[0050] The surface-mount temperature sensor 335 is located directly below the bottom of the cup 4. The outer surface of the drive motor 3381 is fixed to the center of the heat sink 337. The bottom of the support plate 339 is fixed to the bottom of the inner wall of the outer casing 331.
[0051] The overall working principle is as follows:
[0052] This device relates to an intelligent thermos cup that integrates active cooling, heating, stirring, temperature control display, and efficient heat dissipation. Its working principle is a precise process involving the coordinated operation of multiple systems, as detailed below:
[0053] First, the user inserts the DC output plug of the external power adapter into the charging plug 323 located on the annular housing 321. Electrical energy is then transmitted via wires to the internal power management module 324. This module is a highly integrated control core PCB board, where its internal MCU microprocessor, voltage conversion circuit, and charging management chip begin operation. The power management module 324 performs two tasks: 1) distributing power to the entire system, including the thermoelectric cooling module 336, motor, display, and control systems; 2) simultaneously charging the backup battery module 325, i.e., the lithium polymer pouch battery, for mobile use. The user then sets the operating mode and temperature using buttons.
[0054] Subsequently, the power management module 324 outputs direct current in a specific direction to the thermoelectric cooling module 336 according to user instructions. When the current flows through the semiconductor couple inside the thermoelectric cooling module 336, the Peltier effect occurs:
[0055] In cooling mode, the current direction causes the cold end (upper surface) of the thermoelectric cooling module 336 to absorb heat and the hot end (lower surface) to release heat. The cooling energy is efficiently conducted to the bottom of the cup 4 through the heat transfer plate 334 that is in close contact with it, ultimately cooling the liquid inside the cup.
[0056] In heating mode, the current direction is reversed, the hot and cold ends of the thermoelectric cooling module 336 are interchanged, and the heat is used to heat the liquid through the above path.
[0057] A surface-mount temperature sensor 335 is always tightly attached to the surface of the heat transfer plate 334 with thermally conductive silicone grease, monitoring its temperature changes in real time. This data is fed back to the MCU on the control circuit board 332 in real time. The MCU uses a built-in algorithm to convert it into an estimated liquid temperature and drives the LCD screen 322 to display it. This solves the problem of traditional cups not being able to know the real-time temperature, avoiding discomfort caused by drinking water that is too hot or too cold, forming a precise intelligent closed-loop temperature control system.
[0058] Meanwhile, to address the issue of liquid temperature stratification within the cup caused by temperature differences (e.g., the bottom is cold and the top is hot during cooling), the stirring system is activated simultaneously.
[0059] The drive motor 3381 receives a command and begins to rotate, causing the drive magnet 338 on its output shaft to rotate synchronously. The rotating magnetic field of the drive magnet 338 penetrates the heat sink 337, the thermoelectric cooling module 336, the heat transfer plate 334, and the bottom of the cup 4, driving the synchronous rotation of the magnetic rotor 311 and the stirring blade 312 inside the cup through magnetic coupling. This design solves the leakage and sealing problem that may occur in traditional stirring devices where the rotating shaft needs to penetrate the cup wall.
[0060] The magnetic rotor 311 magnetically attracts the stirring blades 312, causing them to rotate at high speed and agitate the liquid. When the liquid flows through the stationary turbine guide shroud 313, the internal guide ribs transform the parallel flow into a violent turbulent flow, ensuring that the liquid temperature in the entire cup is rapid, uniform, and consistent, significantly shortening the time required for cooling or heating.
[0061] The turbine guide cover 313 is fixed to the inner wall of the cup body 1 by mutual attraction between the first magnetic block 314 on its inner wall and the second magnetic block 315 on the inner wall of the cup body 1. This design can limit the position of the turbine guide cover 313, avoiding the risk of burns, component damage, and interruption of use caused by the entire stirring component accidentally slipping off due to gravity or inertia when the user picks up the cup to drink or move it; at the same time, since there are fan blades inside the bottom of the cup, stains will accumulate on the bottom after a short period of use, which will make it difficult to clean. Therefore, the detachable fixation by magnetic attraction also ensures the convenience of subsequent cleaning.
[0062] Finally, during operation, the thermoelectric cooling module 336 generates a large amount of waste heat at its hot end. If this heat is not dissipated in time, it will cause the module to overheat and fail. Therefore, this device also incorporates a composite heat dissipation scheme:
[0063] 1. The heat generated by the hot end of the thermoelectric cooling module 336 is first absorbed by the heat sink 337 that is in close contact with it below. The heat dissipation copper pipe 3371 (filled with coolant) embedded in the fins of the heat sink 337 utilizes the efficient heat transfer characteristics of liquid phase change to rapidly diffuse the heat from the local hot spot to the entire heat sink 337.
[0064] 2. Subsequently, the cooling fan 3382 starts, drawing in cool air from the ventilation grille 333 of the casing 331, generating a forced airflow that blows across the fins of the heatsink 337, converting the heat on the fins into hot air through convection heat transfer and expelling it. This "liquid cooling + air cooling" composite heat dissipation system solves the problem of performance degradation and shortened device lifespan caused by insufficient heat dissipation under high power density, enabling the product to maintain a compact and lightweight design while continuously and stably operating at high performance.
[0065] It should be noted that when the user unplugs the power cord, the power management module 324 automatically switches to power from the backup battery module 325. To maximize battery life, the system intelligently shuts down the high-power thermoelectric cooling module 336, but continues to power the drive motor 3381, temperature sensor, and display system. During this time, the stirring function continues to operate, maintaining a uniform liquid temperature within the cup to slow down temperature changes. The LCD screen 322 continues to display the real-time temperature, solving the problem of the product completely failing after being disconnected from the power source and providing a practical function for short-term portable use.
