Description

Technical Field

[0001] The utility model relates to the technical field of water drinking machines, in particular to a liquid level sensing water-saving water drinking machine. Background Art

[0002] A bottled water dispenser is a device used to store and supply bottled water. It usually consists of a bracket or rack, an electric pump and a water storage barrel for bottled water. Users can put large barrels of water into the water storage barrel, and then the electric pump will pump out the drinking water stored in the water storage barrel for users to drink. This device is usually used in homes, offices or other places to facilitate users to obtain clean and safe drinking water at any time.

[0003] In response to the above problems, the Chinese publication number: CN208769527U "An intelligent water dispenser with quantitative water output function" adds drinking water through the water inlet pipe, passes the drinking water through the filter plate, filters the water body, and then sets the coefficient of the electric spring rod through the touch panel, selects the hot water tank and the cold water tank as needed, and then fills the cup with water through the solenoid valve, and closes the solenoid valve through the placement frame and the second switch, thereby performing quantitative water output operation and reducing unnecessary waste.

[0004] However, this type of water dispenser still has certain defects when in use. For example, this type of water dispenser controls the water output of the water dispenser through a solenoid valve and a switch.

The two limiting holes 402 are provided with limiting cylinders 302, and one end of the two limiting cylinders 302 extends into the lifting chamber 108 and is sleeved with a spring 303. The tops of the two limiting cylinders 302 are fixedly connected to U-shaped connecting rods 301, and one end of the two U-shaped connecting rods 301 extends into the water receiving chamber 101. The electric hot water tank 102 is located inside the equipment cavity 110, and a heating pipe is provided inside the electric hot water tank 102. One end of the water pump 106 is connected to the water pump pipe 104, and the water pump 106 is connected to the electric hot water tank 102 through the water pump pipe 104.

[0034] When in use, the user can place bottled water on the top of the water dispenser housing 1 to allow the water to flow into the water cavity 6. The water entering the water cavity 6 flows into the electric water tank 102 through the water pipe a109 to be heated.

[0035] Among them, a hot water guide pipe 401 is connected to the bottom of the inner wall of the hot water temporary storage chamber 4, and the hot water guide pipe 401 is connected to the hot water pipe 107 through a three-way pipe, a cold water guide pipe 505 is provided at the bottom of the inner wall of the cold water temporary storage chamber 504, and the cold water guide pipe 505 is connected to the cold water pipe 502 through a three-way pipe, and solenoid valves are provided on the cold water guide pipe 505, the outlet pipe a105, the cold water temporary storage chamber 504, the hot water drainage pipe 103, the hot water guide pipe 401 and the cold water drainage pipe 501, and water stop valves are provided on the hot water drainage pipe 103 and the cold water drainage pipe 501; electromagnets 306 are provided at both ends of the pull rod 3, iron sheets 307 are provided on both sides of the water receiving chamber 101, the two iron sheets 307 are magnetically connected to the two electromagnets 306 respectively, and scales are provided on one side of the two iron sheets 307.

[0036] When receiving hot water, the user can start the water pump 106 through the control panel arranged on one side of the cleaning box 2 to extract the hot water inside the electric hot water tank 102, so that the hot water enters the hot water temporary storage chamber 4 through the water pumping pipe 104 and the water outlet pipe a105, and then when the hot water contacts the liquid level sensor 305 inside the hot water temporary storage chamber 4, the liquid level sensor 305 generates an electrical signal and sends it to the control terminal, thereby closing the water pump 106, terminating the inflow of hot water, and opening the solenoid valve on the hot water guide pipe 401 at the same time, so that the hot water in the hot water temporary storage chamber 4 flows out from the hot water pipe 107.

[0037] When receiving cold water, the water in the water chamber 6 flows into the cold water temporary storage chamber 504 through the water pipe b5 and the water outlet pipe b503. When the water in the cold water temporary storage chamber 504 contacts the liquid level sensor 305 inside the cold water temporary storage chamber 504, the liquid level sensor 305 generates an electrical signal and sends it to the control terminal, thereby closing the solenoid valve on the water outlet pipe b503 and opening the solenoid valve on the cold water guide pipe 505, thereby allowing the cold water to flow out through the cold water pipe 502.

[0038] When it is necessary to adjust the water output according to the capacity of the cup, the user turns off the electromagnets 306 at both ends of the pull rod 3 through the control panel set on one side of the cleaning box 2, and then pushes or pulls the pull rod 3 upward or downward, so that the U-shaped connecting rod 301 drives the liquid level sensor 305 at the bottom of the placement plate 304 to move upward or downward. At this time, the pull rod 3 is moved to the relative scale according to the capacity of the cup, so as to change the position of the liquid level sensor 305, thereby adjusting the amount of water flowing into the cold water storage chamber 504 and the hot water storage chamber 4.

[0039] In addition, when a power outage occurs, the solenoid valves on the water outlet pipe a105, the hot water guide pipe 401, the water outlet pipe b503 and the cold water guide pipe 505 will remain closed. At this time, the user can turn the water stop valve on the hot water guide pipe 103 or the cold water guide pipe 501 to allow the water in the electric hot water tank 102 to flow out through the hot water pipe 107, or allow the water in the water chamber 6 to flow out through the cold water pipe 502.

[0040] Among them, the model of the liquid level sensor 305 can be YW-01. The liquid level sensor 305 is composed of conductive material and insulating material. When the liquid contacts the metal part, a conductive path is formed. The resistance value of the conductive material changes, and an electrical signal is generated and transmitted to the control terminal, so as to determine the liquid level height, thereby realizing the measurement and monitoring of the liquid height. This solution does not make any improvements to the circuit or program of the liquid level sensor 305, so the circuit and signal connection relationship of the liquid level sensor 305 will not be elaborated.

[0043] During use, the user can pull down the C-shaped sealing plate 701 to separate the magnet 702 and the iron block 703 from each other, thereby opening the cleaning chamber 205, and then place the cup with the mouth facing downward into the U-shaped cleaning seat 8, and extend the nozzle 803 into the cup. At this time, pull up the C-shaped sealing plate 701 to make the magnet 702 fit with the iron block 703, thereby sealing the cleaning chamber 205, and then start the water pump 203 to pump out the water in the water storage chamber 201, so that the water passes through the guide pipe a202 and the guide pipe b204, enters the water spray chamber 801 and the connecting pipe 804, and then is sprayed out through the water spray hole 802 and the nozzle 803 on the U-shaped cleaning seat 8, so as to rinse the dirt on the inner and outer walls of the cup.
