Description

TECHNICAL FIELD

[0001] The utility model relates to container water temperature and liquid level detection technology, especially a multipurpose integrated induction water detection assembly and scented tea pot thereof. BACKGROUND

[0002] In the use process of the water heating container, the liquid level detection is a very key link, because the height of the liquid level will directly affect the use effect of the water heating container. In the existing liquid level detection method, including the traditional liquid level detection method, the ultrasonic liquid level detection method and the capacitive liquid level detection method.

[0003] The traditional liquid level detection method usually uses a floating ball or an iron hook for detection, that is, the start and stop switch of the heating container is controlled according to the height of the water level. This method is simple and easy to implement, but the floating ball and the iron hook are easily affected by the environment, and are easily contaminated or damaged, thereby affecting the cleanliness and service life. The ultrasonic liquid level detection method measures the height of the liquid level by using the principle of ultrasonic waves, and has the advantages of high precision, strong stability and fast response speed. Its working principle is that the ultrasonic sensor emits a certain frequency of sound wave signal, when the sound wave meets the liquid surface, part of the sound wave is reflected back to the sensor, and is converted into an electric signal inside the sensor, and the height of the liquid level is calculated. The ultrasonic liquid level detection method is suitable for various types of water heating containers and water dispensers, but its cost is relatively high.

[0004] The capacitive liquid level detection method measures the height of the liquid level by using the principle of capacitance. The sensor inside contains a capacitive element. When the liquid level rises, the capacitance value between the liquid and the capacitive element changes. The height of the liquid level is determined by measuring the change of the capacitance value. The capacitive liquid level sensor has the advantages of non-contact measurement and fast response speed. However, the existing capacitive liquid level detection device has a relatively complex installation process and high cost.

[0005] Moreover, in the existing water heating container, when the capacitive liquid level detection is used, the liquid level detection chip and the temperature detection chip are usually placed in different areas of the container for control, so that the water signal for detecting the liquid level and the signal for detecting the temperature are separately processed by two modules, the water signal for detecting the liquid level is processed at the same time as the water plate signal, and the signal for detecting the temperature is led to the main control board for processing by a long wire. Due to the long wire, the detection electric signal is attenuated and weakened, thereby causing inaccurate measurement of the temperature and resulting in distorted detection results. SUMMARY
