[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Example:

[0019] See also Figure 1-4 The utility model provides a technical solution: a quantitative water outlet device for a liquid heater, comprising a support shell 2, a water outlet 3 is arranged inside the support shell 2, a hose 5 is plugged into the upper end of the water outlet 3, and the hose 5 is made of food-grade silicone, so that the hose 5 has the advantages of being soft, elastic, resistant to kinking and not deforming;

[0020] A clamping frame 6, the clamping frame 6 is connected to the lower surface of the support shell 2 and is located on the side of the water outlet 3, an ultrasonic distance sensor 7 is installed inside the clamping frame 6, a limit strip 8 is installed on the lower surface of the clamping frame 6, and a push seat 9 is provided on the side of the ultrasonic distance sensor 7, the push seat 9 is located between the limit strip 8 and the clamping frame 6 and is slidably connected to the limit strip 8;

[0021] The ultrasonic distance measuring sensor 7 has an ultrasonic transmitter and an ultrasonic receiver. The ultrasonic transmitter transmits an ultrasonic wave, and timing starts at the same time as the emission time. When the ultrasonic wave encounters the water cup and the water, the reflected ultrasonic wave is received by the ultrasonic transmitter. By measuring the time difference between the ultrasonic wave emission and the reflected wave, combined with the speed of sound, the height difference between the water cup and the water level is confirmed, and then the water in the water cup is calculated to determine whether it is full.

[0022] The ultrasonic distance measuring sensor 7 is electrically connected to a main control board 10 , and a heat insulating seat 13 is disposed on the lower surface of the main control board 10 . The heat insulating seat 13 can prevent the heat of the hot water from affecting the normal operation of the main control board 10 .

[0023] In this embodiment, if Figure 1 As shown, the right end of the support shell 2 is fixedly connected to the outer shell 1, and a water supply pipe 4 is provided inside the outer shell 1, and the water supply pipe 4 is connected to the hose 5, and the water supply pipe 4 is connected to the water outlet 3 of the water pump 11. The water pumped by the water pump 11 is discharged through the water supply pipe 4, the hose 5, and the water outlet 3.

[0024] In this embodiment, if Figure 4 As shown, the main control board 10 is electrically connected to the water pump 11, the main control board 10 is installed on the inner wall of the shell 1, and the surface of the shell 1 is provided with openings corresponding to the buttons of the main control board 10, the main control board 10 supplies power to the ultrasonic ranging sensor 7, and the ultrasonic ranging sensor 7 detects the height difference between the mouth of the water cup and the water level through ultrasonic waves to determine the water level in the water cup.

[0025] In this embodiment, if Figure 2 As shown, the clamping frame 6 has an anti-slip strip 12 inside, and the ultrasonic ranging sensor 7 is slidably connected to the anti-slip strip 12. The ultrasonic ranging sensor 7 is clamped by the anti-slip strip 12 to prevent the ultrasonic ranging sensor 7 from sliding freely.

[0026] Specifically, when in use, when the water cup is placed under the water outlet 3 to receive water, the water pump 11 is started to pump water. After the water enters the water cup, the height of the cup mouth of the water cup remains unchanged. At this time, the ultrasonic ranging sensor 7 detects the rise of the water level. At this time, the height difference between the water level and the height of the cup mouth gradually decreases. When the height difference reaches the set threshold, the main control board 10 receives the electrical signal of the ultrasonic ranging sensor 7, and the main control board 10 controls the water pump 11 to shut down. When the water cup is about to be filled with water, the water outlet 3 can stop discharging water.
