Embodiment 1

[0033] Example 1: A water level sensor, such as figure 1 , 2 As shown, it includes 3 metal electrodes. One end of each metal electrode is exposed as the detection terminal 2, and the other end 28 is fixed in an insulating fixing member 3, and is connected to the signal output wiring harness 4 in the insulating fixing member 3. The signal output wiring harness 4 is further composed of an aviation connector. The core connector 12 is connected to realize a wired connection with an external controller. Or, the other end 28 is connected to a radio frequency wireless communication device 13 based on a SoC computer system on a chip (such as Zigbee) for realizing a wireless connection with an external controller.

[0034] The whole metal electrode, including its detection end 2, is made of a stainless steel rod of 1-6 mm; or only the detection end 2 is made of stainless steel rod or block or tube, and the rest is made of copper wire.

[0035] The metal electrode 1 of the present invention...

Embodiment 2

[0048] A container with a water level measurement and control device formed by using the above-mentioned water level sensor 7: The above-mentioned water level sensor 7 is installed on the top or upper side of the water container 29.

Embodiment 3

[0050] The beverage machine with a liquid level measurement and control device composed of the above-mentioned water level sensor 7 includes 12 beverage boxes 19 in 3 rows and 4 rows. A water level sensor 7 is installed on the top or upper side of the beverage box 19, and a liquid outlet 20 is connected to the beverage box 19.

[0051] There are 12 beverage boxes 19 in 3 rows and 4 columns, which are arranged horizontally and vertically in the freezer 21. The electronically controlled liquid outlet device 23 controls each liquid outlet 20 to output selected beverages with different tastes.

[0052] Each beverage box 19 is provided with a solid beverage mixing and / or homogenizing device 22, which can stir, mix and homogenize the newly added solid or concentrated liquid beverage (such as tea powder, concentrated juice, etc.).

[0053] A self-priming pump 24 is connected to each liquid outlet 20 for extracting the beverage in the beverage box 19. The liquid outlet 25 of the self-primin...

Abstract

The invention discloses a water level sensor as well as a water container and a beverage dispenser comprising the same. The water level sensor comprises one or more metal electrodes, one end of each metal electrode is exposed as a detection end, and the other end of each metal electrode is fixed in an insulating fixing piece and is connected with a signal output circuit in the insulating fixing piece; the signal output circuit is connected with a signal output wiring harness or a radio frequency wireless monitoring circuit. The water level sensor is used for devices with liquid level measurement and control, such as a water container and a beverage dispenser, and is combined with a mapping capacitor and a set change excitation signal such as a square wave, a pulse or an alternating signaland the like generated by computer control; the defects of a magnetic levitation ball dry reed sensor can be overcome, the lowest water level can be detected, water can be completely pumped without remaining water, the problem of waste water of a water dispenser is solved, the problems of rusting and scaling of metal electrodes can be prevented or reduced, and the water dispenser has the advantages of being long in service life, simple in circuit and low in cost.

Description

[0001] Technical field [0002] The invention relates to a water level sensor and a water container and a beverage machine composed of the water level sensor. Background technique [0003] There are float type and electrode type for water level detection. The former is not only expensive, the production and processing technology is troublesome, the production period is long, and the weight of the magnet causes the waterline to be deep, resulting in misdetection because the bottom of the liquid cannot be detected (liquid is shallow and cannot float, for example, a 28mm thick float needs at least 15mm water depth It can only float and be detected), causing a lot of liquid left in the rectangular parallelepiped tank to be drawn out, resulting in a lot of waste; due to the troublesome processing technology, the order production cycle is long; it is not easy to clean, and the middle plastic tube is easy to bend and scrap. [0004] The electrode type water level sensor can easily reach th...
