Technical Field
[0001] This utility model relates to the field of thermal insulation container technology, specifically to a thermal insulation container with liquid level display function. Background Technology
[0002] Most traditional insulated containers do not have a liquid level display function, which is inconvenient to use. Some insulated containers do have a liquid level display function, but the liquid level display of these containers is either directly observed in the inner tank through a transparent window, or the liquid level is displayed by setting a float. Such structural designs have at least the following drawbacks:
[0003] 1. A transparent window requires an opening in the insulation layer, which will damage the insulation layer structure and lead to heat loss.
[0004] 2. Buoys and similar instruments are easily affected by scale or tilting, resulting in low accuracy.
[0005] 3. Unable to clearly display liquid level in low-light environments or complex scenarios. Utility Model Content

When the tilt angle of the container body exceeds a set value, the data processing unit corrects the liquid level electrical signal based on the detection value of the triaxial accelerometer.
[0019] Preferably, the insulated container with liquid level display function further includes a lid, which is used to close the opening of the container body. The lid is provided with an interaction module that is connected to the data processing unit via Bluetooth and a touch operation module that is electrically connected to the interaction module. The touch operation module is set corresponding to the touch operation area on the lid.
[0020] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:
[0021] This utility model provides a heat-insulated container with liquid level display function, including a container body with an inner liner and an outer shell located outside the inner liner, and a heat-insulating layer filled between the inner liner and the outer shell.

[0026] like Figures 1 to 3As shown, the insulated container with liquid level display function provided by this utility model includes: a container body 10 and an insulation layer 20. The container body 10 adopts a double-layer vacuum stainless steel structure. Specifically, the container body 10 includes an inner liner 11 for holding liquid (usually water) and an outer shell 12 located outside the inner liner 11. The inner liner 11 is made of cylindrical transparent material, and the outer wall is coated with a reflective insulation layer. The insulation layer 20 is filled between the inner liner 11 and the outer shell 12, and the insulation layer 20 is an aerogel insulation material. The outer shell 12 is provided with a dynamic display system for displaying the liquid level in the inner liner 11. The dynamic display system includes a transparent column assembly and a dynamic marking assembly set on the transparent column assembly. The transparent column assembly is a double-layer vacuum glass tube 13. The dynamic marking assembly includes a transparent conductive film 14 (ITO) coated on the outer wall of the double-layer vacuum glass tube and an LED light strip (not shown in the figure) embedded in the double-layer vacuum glass tube. The liquid level height is marked by changes in the brightness or color of the light strip, and the liquid level marking accuracy is <1m. The insulation layer 20 supports ambient light adaptive brightness adjustment and low power saving mode. At the bottom of the insulation layer 20, there is a weight sensing module 21, a data processing unit 22, and a power supply module. The weight sensing module 21 is used to detect the weight of the liquid contained in the inner liner 11. The data processing unit 22 is electrically connected to the weight sensing module 21, the transparent conductive film 14, and the LED light strip. The data processing unit 22 has preset density values of the liquid contained in the inner liner 11 and geometric parameters of the inner liner 11. The data processing unit 22 receives the weight detection value from the weight sensing module 21, calculates the liquid volume V based on the weight detection value and the liquid density value, calculates the liquid level based on the geometric parameters of the inner liner 11, and outputs the corresponding liquid level electrical signal to the transparent conductive film 14 and the LED light strip to make them emit light, thereby displaying the liquid level and realizing liquid level visualization. The power supply module is electrically connected to the weight sensing module 21 and the data processing unit 22, and is used to supply power to the weight sensing module 21 and the data processing unit 22. The advantage of this setup is that it can display the liquid level in low-light environments or complex scenarios, and there is no need to open windows in the insulation layer, resulting in good sealing.
[0027] In this embodiment, a double-layer vacuum glass tube 13 is embedded in the outer shell 12, and a portion of the outer wall of the double-layer vacuum glass tube 13 is exposed to form a vertical display strip. Specifically, a vertical groove 121 is provided on the outer shell 12 to expose this portion of the outer wall of the double-layer glass tube 13. Furthermore, the outer wall of the double-layer vacuum glass tube 13 does not protrude from the outer shell 12. A portion of the double-layer vacuum glass tube 13 is embedded in the insulation layer 20, and the outer wall of the double-layer vacuum glass tube 13 is spaced apart from the inner liner 11.
[0028] In this embodiment, the weight sensing module 21 is disposed above the data processing unit 22. The weight sensing module 21 has a strain gauge weighing sensor array with a resolution of ±2g and supports temperature drift compensation. The data processing unit 22 has a built-in MCU controller. The power supply module includes a rechargeable lithium battery (not shown in the figure) and a wireless charging coil 23, which surrounds the outside of the data processing unit 22.
[0029] In this embodiment, the data processing unit 22 integrates a temperature sensor and a triaxial accelerometer. The data processing unit 22 corrects the liquid density value based on the detection value of the temperature sensor, specifically calculated as: (ρ = 999.97 - 0.0642T + 0.0085T², where T is the temperature in Celsius). When the detected water temperature is >90°C, the data processing unit 22 automatically switches to high-temperature density compensation mode. The triaxial accelerometer is used to detect the tilt angle of the container body 10. When the tilt angle of the container body 10 is >5°, the data processing unit 22 corrects the liquid level electrical signal based on the detection value of the triaxial accelerometer, using the following correction formula: Where θ is the tilt angle and r is the inner radius.
[0030] In this embodiment, the insulated container with liquid level display function also includes a lid 30, which is used to close the opening of the container body 10. The lid 30 is provided with an interaction module 31 that is connected to the data processing unit 22 via Bluetooth and a touch operation module 32 that is electrically connected to the interaction module 31. The interaction module 31 supports touch wake-up and Bluetooth connection to mobile terminals. The interaction module 31 also supports functions such as voice prompts, water drinking plan settings and low liquid level alarms. The alarm method can be implemented by multi-level warnings using a buzzer, vibration motor and OLED screen. The touch operation module 32 is set corresponding to the touch operation area on the lid 30.
