[0002] The oil filter, also known as the oil filter, is used to remove impurities such as dust, metal particles, carbon deposits and soot particles in the oil to protect the engine. When producing the filter, it is necessary to ensure that the filter tank is sealed and cannot leak. Patent application number: CN201721104397.4 discloses a filter air tightness detection device, including: a water pool, a water level sensor, a support frame, a controller, an electrical cylinder, a sealing cover, a water cylinder, a support plate, a fixed cylinder, and a top frame. It is characterized in that: a water level sensor is attached to the inner wall of the water pool. A support frame is fixed to the upper plane of the pool by bolts, and a controller and an electrical cylinder are installed on the upper plane of the support frame by bolts. The electrical cylinder is connected to a sealing cover through an air pipe. During inspection, the sealing cover is connected to the oil outlet of the filter, and then the filter is placed in the support plate, and the filter is put into the water. The water level rises. When the water level reaches the water level sensor, the electrical cylinder pumps air into the filter, and the water cylinder stops at the same time. Then the worker observes whether there are bubbles. However, this type of detection device can only detect one filter at a time, resulting in low detection efficiency.
