Description

Technical Field

[0001] This utility model relates to the field of thermos bottle technology, and in particular to a thermos bottle that can be heated and cooled. Background Technology

[0002] With the improvement of people's living standards and the increase in outdoor activities, the functional requirements for portable beverage warming devices are becoming increasingly diversified. Traditional thermos bottles mainly rely on vacuum insulation layers to achieve long-term passive insulation (heat preservation or cold preservation), but they cannot actively heat or cool the contents to meet users' needs for enjoying beverages at a suitable temperature immediately.

[0003] Thermos bottles with heating and / or cooling functions on the market have the following defects:

[0004] 1. Products with limited functionality, offering only heating or cooling functions. These products have limited functionality and cannot meet users' flexible needs in different scenarios (such as heating in winter and cooling in summer).

[0005] 2. Integrating both heating elements (such as heating wires) and cooling elements (such as thermoelectric coolers, TECs) inside or at the bottom of the thermos flask offers two functions, but results in increased structural complexity, a larger number of components, and higher manufacturing costs. Furthermore, it cannot optimize convection, leading to uneven temperature distribution and lower efficiency.

[0006] 3. Traditional integrated devices are prone to malfunctions due to accidental button presses. For example, in thermos bottles with integrated heating or cooling elements, although control buttons or operation interfaces are provided, accidental presses or unclear heating / cooling reminders are common in daily use. Utility Model Content

[0007] Therefore, the purpose of this utility model is to provide a thermos bottle for heating and cooling, which has the characteristics of simple structure, high efficiency, and the ability to meet both heating and cooling requirements.

[0008] The technical solution adopted by this utility model to solve its technical problem is as follows:

[0009] A thermos flask for heating and cooling includes a flask body, with a heating device at one end and a cooling device at the other end. The heating device or the cooling device is detachably equipped with a power supply device. The power supply device is provided with a power supply contact ring, and both the heating device and the cooling device are provided with contact pins that can cooperate with the power supply contact ring.

[0010] It also includes a temperature sensor and a control module. The power supply unit is equipped with an alarm device. When the temperature sensor detects that the temperature inside the bottle is continuously higher than a set threshold, the control module triggers the alarm device.

[0011] The heating device is equipped with an FPC heating module, which includes a heating film that evenly covers the inner wall of the bottle.

[0012] One end of the bottle body is the bottle mouth, and a bottle cap is threadedly connected to the bottle mouth. The refrigeration device is located on the bottle cap.

[0013] The refrigeration device is a semiconductor refrigeration module, which includes a cold end formed by a refrigeration patch, which is disposed on the side of the bottle cap facing the bottle opening.

[0014] The power supply device contains a battery, and a charging connector and indicator light are located on the outside of the power supply device.

[0015] The control module is located in the refrigeration unit, and the alarm device is located in the power supply unit. The alarm device is a buzzer.

[0016] The power supply device is connected to the heating device or the cooling device via a snap-fit ​​structure. The snap-fit ​​structure includes a protruding ring on the ring side of the heating device or the cooling device, and a slot on the ring side of the power supply device that can engage with the protruding ring.

[0017] A detachable second bottle is provided inside the inner cavity of the bottle body.

[0018] The bottle body is provided with a heat insulation layer, and the heating film is attached to the inner wall of the heat insulation layer.

[0019] The beneficial effects of this utility model are:

[0020] 1. The heating and cooling devices of this thermos flask are located at opposite ends of the flask body, either at the bottom or top. Each device can be independently powered. Specifically, when the liquid inside the flask needs heating, the power supply is installed at the heating end (bottom of the flask). The heating device operates, and the FPC heating module evenly heats the liquid. When the liquid needs cooling, the power supply is installed at the cooling end. With the flask upright, the end with the cooling device is the top, allowing cooling to proceed from top to bottom, gradually cooling the entire interior. This utilizes the principle of sedimentation of cold media to achieve faster cooling. Users can easily switch between heating and cooling functions according to seasonal or scenario requirements.

[0021] 2. The heating and cooling devices are located at opposite ends of the bottle, and the power supply must be independently selected and installed in the corresponding module. If the power supply is installed on the heating end, the cooling end cannot be powered on, and vice versa. This avoids the risk of malfunction due to accidental button presses, as seen in traditional integrated devices. For example, if a user accidentally activates the heating function when infant formula needs refrigeration, the formula will spoil.

[0022] 3. The power supply unit is powered through the contact pin and the power supply contact ring. The power supply unit is quick to install and remove through the snap-fit ​​structure, ensuring a stable connection and simplifying the operation steps. Attached Figure Description

[0029] To make the technical problem solved by this utility model, the technical solution adopted, and the technical effect achieved clearer, the technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely for explaining this utility model and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to this utility model are shown in the accompanying drawings, not all of them.

[0030] Reference Figure 1 This utility model proposes a thermos bottle for heating and cooling, including a bottle body 1, with a heating device 3 at one end and a cooling device 2 at the other end. A power supply device 4 is detachably installed on either the heating device 3 or the cooling device 2. (Refer to...) Figure 3 , Figure 4 The power supply device 4 is equipped with a power supply contact ring 40, and the heating device 3 and the cooling device 2 are both equipped with contact pins 5 that can cooperate with the power supply contact ring.

[0031] Specifically, the heating device 3 and the cooling device 2 of this thermos bottle are respectively located at both ends of the bottle body 1, that is, the upper end or the lower end of the bottle body, and the heating device 3 and the cooling device 2 can be independently equipped with a power supply device 4 to supply power to the corresponding device for operation.

[0032] During use, when the liquid inside bottle 1 needs to be heated, the power supply unit 4 is installed at one end of the heating device 3, i.e., the bottom of bottle 1. At this time, the heating device operates, and the FPC heating module evenly heats the liquid inside the bottle. When the liquid inside bottle 1 needs to be cooled, the power supply unit 4 is installed at one end of the cooling device 2. In this case, when bottle 1 is placed vertically, the end with the cooling device 2 can be considered the top, i.e., the top of bottle 1. Cooling proceeds from top to bottom, gradually cooling the entire interior of bottle 1. The cooling effect is achieved faster by utilizing the principle that the cold medium inside bottle 1 easily settles. Users can freely choose between heating and cooling according to seasonal or scenario requirements, making function switching convenient.

[0033] Furthermore, the heating device 3 and the cooling device 2 are located at opposite ends of the bottle body 1, and the power supply device 4 must be independently selected and installed in the corresponding module. When the power supply device 4 is installed on the heating end, the cooling end cannot be powered on; conversely, this thermos corresponds to one power supply device 4, which can only be installed on either the heating device 3 or the cooling device 2. If the power supply device 4 is installed on both the heating device 3 and the cooling device 2, the system will neither heat nor cool, and the buzzer inside the power supply device 4 will sound an alarm. This avoids the risk of malfunction caused by accidental button presses in traditional integrated devices. For example, if a user accidentally activates the heating function when baby milk needs to be refrigerated, the milk will spoil. Optionally, status indicator lights can be installed on the heating device 3 and the cooling device 2 respectively to more intuitively indicate to the user whether the device is heating or cooling. When the heating device 3 is running, the status indicator light displays warm colors such as red and orange; when the cooling device 2 is running, the status indicator light displays cool colors such as blue.

[0034] Specifically, there are two contact pins 5 and two power supply contact rings 40, forming a power supply circuit. A spring is installed inside the contact pin 5, ensuring a stable engagement when the contact pin 5 and power supply contact ring 40 are aligned. The design of the contact pin 5 and power supply contact ring 40 achieves stable contact and energization. When the power supply device 4 is installed using a snap-fit ​​structure, only the physical connection needs to be considered.

[0035] Optionally, refer to Figure 2 , Figure 6 One end of the bottle body 1 is the bottle mouth 10, and a bottle cap is threadedly connected to the bottle mouth 10. The heating device 3 is located on the bottle cap.

[0036] Reference Figure 3The power supply unit 4 contains a battery, and a charging connector 41 and an indicator light 42 are located on its exterior. Optionally, the battery capacity is a 4000mAh lithium battery, supporting Type-C fast charging, and its battery life is sufficient for 12 hours of continuous heating or cooling on a full charge. The indicator light is a three-color LED light: red when the remaining power is enough for 1 hour of operation; red when charging; green when fully charged; and blue when working normally.

[0037] Reference Figure 6 The heating device 3 is equipped with an FPC heating module, which includes a heating film that evenly covers the inner wall of the bottle 1. Specifically, after the FPC heating module 20 is activated, it maintains the temperature inside the bottle at 45℃±3℃.

[0038] The refrigeration device 2 contains a semiconductor refrigeration module that contacts the other end of the bottle 1. The semiconductor refrigeration module includes a cold end formed by refrigeration patches and a hot end made of heat dissipation fins. Specifically, when the semiconductor refrigeration module is in operation, it maintains the temperature inside the bottle at -0℃±5℃.

[0039] Furthermore, the bottle body 1 also includes a temperature sensor and a control module disposed within the bottle body 1. A buzzer is installed within the power supply unit 4. When the temperature sensor detects that the temperature inside the bottle is consistently higher than a set threshold, the control module triggers the buzzer and indicator light, at which point indicator light 42 switches to flashing red. Optionally, the temperature sensor can be disposed on the inner wall of the bottle, and the control module can be integrated into the PCB board of the refrigeration unit 2, adding a temperature comparator unit and alarm logic circuit. The buzzer is a miniature piezoelectric buzzer, embedded inside the housing of the power supply unit 4.

[0040] Reference Figure 6 The power supply unit 4 is connected to the heating device 3 or the cooling device 2 via a snap-fit ​​structure. This snap-fit ​​structure includes a protruding ring 60 on the ring side of the heating device 3 or the cooling device 2, and a slot 61 on the ring side of the power supply unit 4 that engages with the protruding ring 60. This snap-fit ​​structure allows for quick assembly and disassembly of the power supply unit 4, ensuring a stable connection and simplifying operation.

[0041] Alternatively, as another embodiment, the power supply device 4 and the heating device 3 or the cooling device 2 can be connected by threads, and they only need to be tightened together during installation.

[0042] Furthermore, when the heating device 3 or the cooling device 2 is not connected to the power supply device 4, a protective cover can be installed on the other end face of the heating device 3 and the cooling device 2. The mounting interface of the protective cover with the heating device 3 and the cooling device 2 is the same as the mounting interface of the power supply device 4, and can be a snap-fit ​​structure or a threaded connection. This is used to protect the contact pins 5 on the heating device 3 and the cooling device 2.

[0043] The bottle body 1 has an insulation layer inside, and a heating film is attached to the inner wall of the insulation layer. Optionally, the insulation layer is a vacuum double-layer stainless steel liner with a copper-plated layer to enhance the insulation effect.

[0044] Optionally, a removable second bottle is provided inside the bottle body 1. The removable second bottle design allows users to replace the inner liner, expanding the usage scenarios, such as dispensing different beverages, and facilitating cleaning and maintenance.

[0045] In summary, this utility model, with its innovative split layout and modular design, achieves free switching between heating and cooling functions while also possessing advantages such as simplified structure, improved energy efficiency, convenient operation, and low cost. It overcomes the core defects of existing technologies, such as single function, high integration complexity, low temperature control efficiency, and avoids the risk of functional malfunctions caused by accidental button touches in traditional integrated devices.
