Problems solved by technology

[0005] The advantage of the above-mentioned pressure dry inspection method is that the structure is simple, but since the display accuracy of the pressure gauge cannot meet the requirement of displaying a small pressure drop, in most cases it still depends on the experience of the inspector to make a judgment, so this method still has the problem of misjudgment , and it is also impossible to find water seepage with a small leakage in a short time

Embodiment Construction

[0036] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0037] The invention provides a water system leak detection device for a water dispenser, comprising:

[0038] Gas supply system, which degreases and dries the compressed air, and reduces the pressure of the compressed air to the pressure required by the water system of the water dispenser as the detection gas;

[0039] Gas sealing system, which isolates the water system of the water dispenser from the outside world, prevents the leakage of the detection gas filled in the water system of the water dispenser, and transports the detection gas in and out of the water system of the water dispenser;

[0040] Detection and control system, which opens a...

Abstract

The invention discloses a water dispenser used water system leak detection device and method, which mainly adopt the flow interference detection method and a low-cost gas flow detection device consisting of a high-sensitivity gas flow detection pipe and a high-sensitivity induction detector, rather than a high-price precision flowmeter. When the fact that pressure gas for detecting a water system of the water dispenser enters the water system of the water dispenser and is balanced is detected, an air floater inside the gas flow detection pipe can drift as long as leakage exists in the water system of the water dispenser, the displacement of the floater can be detected by the induction detector immediately, and the detecting system locks a signal and alarms immediately.

Description

technical field [0001] The invention relates to the field of water dispenser detection devices, in particular to a water system leak detection device for a water dispenser and a leak detection method thereof. Background technique [0002] The leakage of the water system of the water dispenser is a common problem that has plagued the water dispenser manufacturing industry, and it is also one of the quality problems with the most complaints from customers and the most claim disputes. At present, the water system leak detection method of the water dispenser commonly used in the water dispenser industry is the manual water detection method, that is, the water system of the water dispenser is manually filled with water, and then manually observed for a certain period of time, and judged according to whether there is dripping water. Check for leaks in the water system. [0003] The main disadvantages of the above leak detection methods are as follows: First, manual observation is...
