Description

Technical Field

[0001] The utility model relates to the technical field of water level detection, in particular to a water level detection device, a water level indication device and a water dispenser. Background Art

[0002] At present, new water dispensers such as under-bucket water dispensers and tea bar machines are deeply favored because of their beautiful appearance, high space utilization rate and relatively labor-saving water replacement methods. However, the bucket compartments of such models are often fully enclosed, and users cannot see the remaining water volume in the pure water bucket, which causes inconvenience in use.

[0003] How to more conveniently and timely obtain the remaining water volume in the bucket is the focus of people's attention. For example, patent application No. 201922376388.6 proposes a water dispenser with a water level monitoring function, which uses a capacitive liquid level sensor fixed on an elastic bracket to measure the water level in the bucket. However, the capacitive liquid level sensor requires close contact with the barrel wall, and the mechanical elastic bracket has high requirements for the shape and position of the bucket, increasing the difficulty of water replacement for users.

[0004] Patent application No. 202010298202.4 proposes an under-bucket water dispenser that detects the water level according to the change of the bucket weight. Through a weighing structure composed of a load-bearing platform, a pulley and a spring, an alarm is triggered after the water volume drops to a certain position. However, there are many types of bucket capacities on the market, and the weights after storing water are different. Therefore, this solution cannot automatically adapt to the bucket capacity to adjust the alarm water level during use.

[0005] Patent application No. 202220897686.9 proposes a water level alarm sensor for a water dispenser, which fixes a capacitive water level sensor on a bracket with a strong suction cup. Through the adjustment of the suction cup and the bracket, the sensor is in close contact with the bucket wall. The suction cup of this solution is a passive fixing method, and the smoothness of the bucket wall or the bucket size can seriously affect the adsorption strength of the suction cup. It is basically the same as the principle of measuring the water level by the mechanical fixed capacitive water level sensor proposed in the aforementioned patent application No. 201922376388.6. Both adopt the form of mechanically assisting to fix the capacitive water level sensor, with a small tolerance for the material, size and position of the bucket, which has a negative impact on the user experience.
