Description

Technical Field

[0001] The invention relates to the technical field of water dispensers, in particular to a water dispenser with a photoelectric liquid level sensor. Background Art

[0002] Photoelectric liquid level sensors are widely used in water dispensers. Their working principle is based on the photoelectric effect. Through the combination of light-emitting diodes and photosensitive diodes, they detect changes in light intensity to determine the liquid level. Photoelectric liquid level sensors have the advantages of small size, low power consumption, no mechanical moving parts, and high waterproof grade. They are suitable for use in equipment such as water dispensers with limited space and frequent contact with water. They can accurately detect water level changes, promptly remind users to add water or automatically shut down heating components to prevent dry burning, and ensure safe, energy-saving, and intelligent operation of water dispensers.

[0003] A Chinese patent with announcement number "CN211022263U" discloses a water dispenser, including a water dispenser body, a placement slot is provided at the upper end of the water dispenser body, the upper part of the water dispenser body is a heating chamber, and the heating chamber is connected to the placement slot; a heating structure for heating water is provided in the heating chamber, and a valve connected to the heating chamber is provided on the side of the water dispenser body.

[0004] However, the above structure still has some shortcomings. When the water dispenser is used, the electrical equipment inside the water dispenser will run accordingly, such as water boiling equipment and sensor equipment. These equipment will release a certain amount of heat when running. Generally, water dispensers directly open relative vents to dissipate the heat, but the circulation of air will cause dust and pollutants in the air to float into the water dispenser body. After a long period of accumulation, these dust and pollutants will seriously damage the electrical equipment inside the water dispenser body, thereby reducing the service life of the water dispenser itself. Summary of the invention
