Milk beverage heating mixer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing milk beverage heating mixers face challenges in temperature measurement accuracy due to the thermostat being affected by the hot plate's temperature, leading to poor foaming and taste, and potential safety hazards from through holes, while infrared induction devices are costly and less accurate over multiple heating cycles.
Innovation Solution
A milk beverage heating mixer design featuring a temperature measurement assembly that contacts the side wall of the cup via a lever assembly, avoiding direct contact with the heating plate to improve accuracy and prevent heating by waste heat, and eliminating the need for through holes in the heating plate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the thermostat penetrates through the hot plate to measure temperature, then the temperature measurement structure is simple, but the temperature measurement accuracy deteriorates due to interference from the hot plate's temperature
Solution Approach 1:
The patent extracts the temperature measurement function from the hot plate by placing the thermostat on the side wall of the cup rather than having it penetrate through the hot plate. This separation eliminates the interference from the hot plate's high temperature, allowing accurate temperature measurement without compromising measurement precision.
2Ease of manufacture
If through holes are formed in the hot plate for thermostat mounting, then the thermostat can be installed, but the heating efficiency deteriorates and safety hazards increase
Solution Approach 1:
The patent removes the need for through holes in the hot plate by relocating the thermostat to the cup's side wall. This eliminates the structural compromise to the hot plate, maintaining its integrity and heating efficiency while still enabling thermostat installation through alternative means.
3Power
If the thermostat is exposed to high hot plate temperature during continuous heating, then the heating function is maintained, but the temperature measurement accuracy deteriorates leading to poor foaming quality
Solution Approach 1:
The patent introduces the cup's side wall as an intermediary medium for temperature measurement. Instead of having the thermostat directly exposed to the hot plate's high temperature, the thermostat measures the temperature of the cup wall which indirectly reflects the milk temperature, thereby protecting measurement accuracy while maintaining heating function.
4Measurement precision
If infrared induction device is used to sense temperature, then temperature measurement can be performed, but the cost increases and measurement accuracy decreases during continuous heating
Solution Approach 1:
The patent adopts a simple, cost-effective thermostat that can be easily replaced if needed, rather than using an expensive infrared induction device. This simple thermostat provides sufficient measurement accuracy for the application and maintains stable performance during continuous heating operations.

AI summary
A milk beverage heating mixer comprises a cup, a stirrer, a base, a heating plate, a temperature measurement assembly and a first lever assembly. A cavity for accommodating the cup is formed in an upper end of the base. A first radial opening and a second radial opening are formed in a cavity wall of the cavity. The heating plate is disposed at the bottom of the cavity. The first lever assembly is rotatably disposed outside the cavity, and a protrusion at a first end of the first lever assembly stretches into the cavity via the first radial opening. When accommodated in the cavity, the cup presses the protrusion and pushes the temperature measurement assembly by means of the second end of the first lever assembly to stretch into the cavity via the second radial opening to make contact with a side wall of the cup.
