[0002] The pressure-holding interchangeable vacuum suction device is a device that combines the pressure-holding technology and the vacuum suction technology. It can switch between the vacuum suction mode and the pressure-holding mode to meet the pressure and suction requirements of different operating needs. When the gas or substance in the container needs to be extracted, the device reduces the pressure in the container through a vacuum pump to form a negative pressure, thereby attracting external substances to enter. It is suitable for applications such as substance extraction and gas filtration. During operation, the device will switch to the pressure-maintaining mode, and maintain the pressure inside the container stable by precisely adjusting the inlet valve or exhaust valve to prevent the external environment from interfering with the container pressure. This mode is usually used in situations where stable pressure is required, such as chemical reactions, gas storage, cooling, etc.
