Examples

The embodiment of the utility model relates to a direct water dispenser with a water shortage detection device, as shown in fig. 1, comprising a direct water dispenser body 1, a water tank 10 positioned in the direct water dispenser body 1, and a support frame 20 positioned at the bottom of the water tank 10, wherein a detection component 30 is arranged at the side part of the support frame 20, and the detection component 30 is used for detecting the water level condition in the water tank 10. At water tank 10 bottom, set up support frame 20 in the inside of direct drinking machine body 1 simultaneously, avoided placing the liquid level floater at the inside fluting of water tank 10 and lead to the bacterium to breed unable washing simultaneously, detection assembly 30 can judge according to the water level condition in the water tank 10 simultaneously, can not have external magnetic field interference, and the testing result is accurate, simple and easy convenient to install, is convenient for have the four corners to wash simultaneously.

Further, the bottom surface of the detecting unit 30 is positioned at the same level as the inner bottom surface of the water tank 10. The detecting assembly 30 directly detects whether water exists at the inner bottom surface of the water tank 10, and the detection result is accurate. The sensing capacitance of the water is utilized for detection.

Further, a capacitive sensing chip is disposed inside the detecting component 30. The working principle of the capacitive sensing chip is that the sensing capacitor of water is utilized to detect whether liquid exists, and when no liquid approaches the sensing chip, the sensing chip is disconnected into a high signal due to the existence of distributed capacitors; when the liquid level is gradually increased to approach the sensor, the parasitic capacitance of the liquid is coupled to the static capacitance, so that the final capacitance value of the detection assembly 30 is increased, water is conducted to be a low signal, and the conduction signal is output as a judgment, so that the detection method is simple.

Further, the support frame 20 is L-shaped or U-shaped. The supporting frame 20 mainly aims to provide a placement space for the detection assembly 30, so that the detection assembly 30 is arranged on the side of the detection assembly, and meanwhile, the detection assembly and the inner bottom surface of the water tank 10 are positioned on the same horizontal line, and whether the inner bottom surface of the water tank 10 is lack of water or not is detected by the built-in capacitive sensing chip.

When the warning part 50 is an LED lamp, and water shortage signals are transmitted to the LED lamp for display through a circuit when water shortage exists; when the warning part 50 is a buzzer, the water shortage signal is transmitted to the buzzer through the circuit to make a sound so as to prompt the water tank 10 to reach the water shortage state.

The working principle of the utility model is as follows: the inside of direct drinking machine body 1 sets up a support frame 20, and support frame 20 is located the bottom of water tank 10, sets up a detection component 30 at the lateral part of support frame 20, and detection component 30 inside is provided with capacitive sensing chip, utilizes the induced current of water to detect whether there is liquid to exist in the water tank, and then whether the inside of induction water tank lacks water. When water is on, the signal is low, the anhydrous disconnection is high, and the on signal is output through circuit connection to judge whether water is deficient. When water is lacking, the LED lamp is on or the buzzer can sound so as to remind.
