[0007] Furthermore, the infrared ranging sensor is electrically connected to a main control board, and the main control board is electrically connected to a water pump. The main control board controls the start and stop of the water pump. The infrared ranging sensor provides the main control board with water level data of the water cup, so that the water pump can be shut down in time.

[0008] Compared with the prior art, the beneficial effects of the utility model are:

[0009] (1) The infrared ranging sensor can identify the amount of water in the cup and the height of the cup mouth in real time. When the water reaches a certain water level below the height of the cup mouth, the water will stop flowing. This allows a variety of containers to be filled with water.

[0010] (2) The infrared distance sensor can be adjusted by pushing the seat. When the water cup is of different sizes, the position of the infrared distance sensor can be adjusted to facilitate the infrared distance sensor to more accurately detect the water cup and water level height, and the accuracy of automatic water collection is higher.

[0016] 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.

[0017] Example:

[0018] 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;

[0019] 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 infrared 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, a push seat 9 is provided on the side of the infrared 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;

[0020] The infrared ranging sensor 7 has a laser transmitting head and a laser receiving head. The laser transmitting head emits infrared rays. When encountering the water cup and water, the reflected infrared rays are received by the laser receiving head. By measuring the time difference between the emission and reflection of the light and combining it with the speed of light, the water level in the water cup can be calculated.

[0021] In this embodiment, if Figure 1As 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.

[0022] In this embodiment, if Figure 4 As shown, the infrared ranging sensor 7 is electrically connected to the main control board 10, and the main control board 10 is electrically connected to the water pump 11. The main control board 10 supplies power to the infrared ranging sensor 7. The infrared ranging sensor 7 detects the height difference between the mouth of the water cup and the water level through infrared rays to determine the water level in the water cup.

[0023] In this embodiment, if Figure 2 As shown, the clamping frame 6 has an anti-slip strip 12 inside, and the infrared ranging sensor 7 is slidably connected to the anti-slip strip 12. The infrared ranging sensor 7 is clamped by the anti-slip strip 12 to prevent the infrared ranging sensor 7 from sliding freely.

[0024] 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 infrared 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 infrared 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.

[0025] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
