[0002] A diaphragm is a device used to measure pressure. It consists of one or more metal diaphragms that deform under pressure. Diaphragms are usually used in pressure sensors or pressure gauges to convert pressure changes into mechanical displacement, and then measure and display pressure values ​​mechanically or electronically. In modern industrial production, diaphragms are widely used in many fields, such as electronics, chemicals, and medical care.

[0003] The sealing of the membrane box is directly related to its performance and reliability in actual use. However, the accuracy of conventional leak detection equipment is relatively limited, and it is difficult to accurately detect tiny leaks. This will lead to quality problems in the product during use and even cause safety hazards. At the same time, the operation process is relatively complicated and often requires professional technicians to operate, which not only increases labor costs but also reduces production efficiency. To this end, we propose a membrane box leak detection device to solve the above problems. Utility Model Content
