Description

Technical Field

[0001] This utility model relates to the field of heat preservation equipment technology, and in particular to a heat preservation device with indicator light effect. Background Technology

[0002] While traditional insulated cups can maintain water temperature for a relatively long time, users often cannot accurately determine the water temperature when drinking directly from them, potentially leading to scalding. To address this, modern insulated cups integrate a digital temperature display on the lid. The lid measures and displays the temperature inside the cup after being touched or receiving external pressure.

[0003] However, these types of cup lids mostly rely on thermistors and button batteries to maintain the temperature display function. Their battery life and device lifespan are not ideal. The temperature display function may fail after a few months, and the relevant temperature measuring components cannot be repaired or replaced.

[0004] In addition, there are also thermos cups on the market with electric heating and heat preservation functions. When placed on the heating base, the heating base directly heats the cup body or supplies power to the heating wire inside the cup body to maintain the water temperature in the cup at a suitable drinking temperature.

[0005] However, these types of insulated cups rely on a heating base for use; if detached from the base, they lose their heat preservation and heating functions. Furthermore, many heating bases only have the most basic heating function; even when the cup is empty or contains very little water, or even when the cup is detached, the heating base continues to heat, potentially causing overheating and safety hazards.

[0046] Detailed Implementation

[0047] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0048] Please see Figures 1-9 This embodiment discloses a heat preservation device with indicator light effect, comprising:

[0049] The electrical connection is between the base 100 and the thermos 200;

[0050] The thermos cup 200 includes a shell 210, a temperature control panel 220 and a battery 230 are assembled at the bottom of the shell 210, a heating plate 240 is assembled at the top of the battery 230, and an inner liner 250 is assembled at the top of the heating plate 240.

[0051] The bottom of the thermos cup 200 protrudes from the housing 210 and is provided with a ring contact 260 and a control button 270. The temperature control panel 220 is electrically connected to the ring contact 260, the heating plate 240, the battery 230 and the control button 270. A lampshade 280 is provided at the bottom of the thermos cup 200.

[0052] Two spring terminals 110 are provided at the center of the top surface of the base 100. The spring terminals 110 are electrically connected to the annular contact 260 at the bottom of the thermos cup 200.

[0053] The temperature control panel includes a heating unit, a temperature control unit, a lighting unit, and a power supply unit. The lighting unit is mounted on the inner wall of the lampshade 280.

[0054] The heating unit regulates the heating temperature of the heating plate 240 based on the measured wall temperature of the inner liner 250.

[0055] The lighting unit outputs a lighting effect corresponding to the wall temperature.

[0056] Here, the lighting unit is installed on the inner wall of the lampshade 280, and it changes the lighting effect based on the wall temperature, so that users can intuitively know the temperature of the water in the thermos cup based on the light color, color temperature or flashing effect of the lighting unit.

[0057] For example, blue can represent 30℃, yellow can represent 60℃, and red can represent 90℃. Gradient colors between these colors can be used to represent the temperature values ​​between them. Thus, when a user observes that the light unit emits red light, they can know that the current water temperature is too high and not suitable for drinking; when they observe that the light unit emits blue light, they can know that the current water temperature is around 30℃ and can be drunk directly.

[0058] In addition, the thermos cup 200 has a built-in battery 230 and can be heated and kept warm independently when detached from the base 100, while maintaining the output of the light unit. Compared with existing thermos cups that use the lid to measure temperature, its temperature measurement accuracy and service life are greatly improved.

[0073] Pin 30 of the microcontroller chip U8 is connected to pin 17 of the main control chip U7, and pin 31 of the microcontroller chip U8 is connected to pin 6 of the main control chip U7, in order to receive control commands for the lighting unit.

[0074] Here, the microcontroller chip U8 receives the temperature value transmitted by the main control chip U7, modulates the control command accordingly, and activates each LED to emit a light effect corresponding to the temperature value, so that the user can intuitively see the water temperature in the cup.

[0075] As an optional implementation, the control button 270 is fitted with a contact S1 at its bottom;

[0076] Pin 21 of the main control chip U7 is connected to contact point S1.

[0077] Here, the control button 270 is used to receive control commands, thereby controlling whether the heating plate 240 is in operation.

[0078] As an optional implementation, a power transmission interface 120 is mounted on the side of the base 100;

[0079] Power transmission interface 120 electrical connection terminal CON1.
