Continuous liquid level detection device

Abstract

The invention discloses a continuous liquid level detection device. The device comprises a container used for containing liquid, a connecting pipe and a sensor module, wherein one end of the connecting pipe is connected with the bottom of the container, the sensor module is connected with the other end of the connecting pipe, the sensor module comprises a detection unit for real-time detection, adetection signal processing unit, a decoding output unit used for outputting signals to external equipment, and a conversion unit used for converting the detection range information, the detection processing unit is respectively connected with the decoding output unit and the conversion unit, the detection unit transmits a detected signal to the detection signal processing unit, and the conversionunit is connected with a display. The device is advantaged in that the detecting unit is connected with a container through the connecting pipe, the detecting unit can continuously detect the liquidlevel of a container through utilizing change of the air pressure in the connecting pipe, the detecting unit does not need to make direct contact with liquid or make contact with the liquid through avisible medium, so cleaning is easy, the liquid cannot be polluted, and precision is high.

Description

technical field [0001] The invention relates to the field of liquid detection devices, in particular to a continuous liquid level detection device. Background technique [0002] At present, there are many ways to detect liquids in kitchen and household electronic products that contain liquid or need to use liquid in the process of processing, such as water dispenser, coffee machine, water purifier, tea maker and other products. There are mechanical, optical, capacitive, gravity, and electrode detection methods. There are the following problems in this detection method: 1. Too much or too little needs to come into contact with the liquid, or come into contact with the liquid through other media; 2. The cleaning is complicated, and bacteria are easy to breed; 3. The installation process is highly demanding, and it needs to be used through design changes; 4. The detection accuracy of liquid is poor; 5. The most important thing is that it cannot detect continuously, only through...
