Description

Technical Field

[0001] The utility model relates to a water level sensor and a water container bottle mouth matching device thereof. Background Art

[0002] There are many existing water tank water level detection and control methods, most of which use float switches to detect water levels. The float switch consists of a reed switch and a magnetic float. When there is no water in the water tank, the magnetic float sinks away from the reed switch and the reed switch is disconnected; when there is water in the water tank, the magnetic float floats up close to the reed switch and the reed switch is closed. By detecting the disconnection or closing state of the reed switch, it can be determined whether there is water at the location of the float switch. However, the existing float switch still has the following shortcomings: (i) When multiple water levels need to be detected, the number of float switches needs to be increased accordingly. Generally, one float switch corresponds to one water level. (ii) In addition, since the float switch is large and expensive, and there are many gaps that cannot be cleaned, resulting in sanitary dead corners, on the other hand, the movable float is easily affected by foreign matter in the water (such as scale, etc.), causing it to be blocked and unable to move and fail. (iii) Moreover, when there are many water levels to be detected, multiple float switches need to be installed, which is complicated to install. The water tank has many holes and is prone to water leakage, and it is more difficult to clean. (iv) The float (especially the steel ball and the magnet inside it) is heavy. When there is not enough water to make the float float, there will still be a certain amount of water in the water tank, resulting in residual water. This will cause the newly added water to be contaminated and become bacteria-free and not fresh, which will make it undrinkable or unusable. Utility Model Content

[0013] Furthermore, the water absorption hole is arranged in the middle of the mounting seat, and the lower end of the water absorption hole is detachably or fixedly connected to the water absorption pipe for extracting water stored in the container, and the water pipe joint is integrally formed with the mounting seat.
