Description

Technical Field

[0001] The invention belongs to the field of non-contact photoelectric liquid level sensor water dispensers, and in particular relates to a water dispenser based on the non-contact photoelectric liquid level sensor. Background Art

[0002] The non-contact photoelectric liquid level sensor detects the liquid level through an infrared transmitting tube and a photosensitive receiver. When the liquid level changes, the refraction or reflection characteristics of light in the liquid will change, thus affecting the light intensity received by the photosensitive element. By measuring the change in light intensity, the rise and fall of the liquid level can be accurately detected. The water dispenser is usually equipped with a water storage bucket or water tank. The user only needs to connect the water source to the water dispenser and turn on the power to start using it. When using it, you can choose hot water or cold water as needed. At the same time, the non-contact photoelectric liquid level sensor is an indispensable electronic component of the water dispenser in the water dispenser use system.

[0003] At present, there are two main fixing structures for traditional non-contact photoelectric liquid level sensors in water dispensers. One is to fix them with cable ties, which requires more reliance on external connections. If the cable ties are cut during disassembly, new cable ties need to be purchased and replaced to reinstall and fix them, and the sensing position is also prone to change. The second is a liquid level sensor with mounting ears, which requires special tools combined with a large number of screw fasteners for installation and fixation. In addition to relying on external tools during disassembly and assembly, problems such as rust, oxidation and thread slippage of the fastening screws may sometimes occur. Summary of the invention
