Background
The filter device is a structural device which communicates an internal gas path after the gas collecting seat and the filter are assembled, the sealing performance of the device is usually realized by installing an O-shaped ring between structural members or locking threads and the like, and after the connection is finished, specific gas circulates through a specified gas path to finish circulation. The structural device ensures good air tightness in the processes of initial assembly, middle-period inspection, later maintenance and the like. If the filter device is not tightly connected, on one hand, external air can permeate into the device to influence the flow rate and the gas concentration of the gas path, and dust particles in the environment can also enter the gas path channel, so that the gas path is easy to block; on the other hand, gas in the gas circuit also leaks from the joint, which not only harms the health of operators, but also influences the accuracy of product ventilation. Therefore, an effective tightness detection means is required to ensure that the filter is in a normal operation state.

Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1, the detection device for a filter sealing structure according to the present invention comprises an air pump 3, a filter sealing device 2, an air inlet flow meter 1 and an air outlet flow meter 4; the air inlet end of the air pump 3 is connected with the filter sealing device 2 through an air inlet pipe, and the air outlet end of the air pump 3 is connected with the filter sealing device 2 through an air outlet pipe; the air inlet end of the filter sealing device 2 is connected with the air inlet flow meter 1 through an air inlet pipe, and the air outlet end of the filter sealing device 2 is connected with the air outlet flow meter 4 through an air outlet pipe; the air inlet flowmeter 1 and the air outlet flowmeter 4 are respectively provided with an air inlet 7 and an air outlet 8; an inlet passage is formed from the inlet flow meter 1 to the filter sealing device 2 to the air pump 3, and an outlet passage is formed from the air pump 3 to the filter sealing device 2 to the outlet flow meter 4.
When the air pump is used, the power of the air pump 3 is adjusted by setting the power supply voltage value, under the action of the negative pressure of the air pump 3, external air enters from the air inlet 7 of the air inlet flowmeter 1, sequentially flows through the air inlet flowmeter 1, the filter sealing device 2 and the air pump 3, flows from the air pump 3 to the filter sealing device 2, flows through the air outlet flowmeter 4, flows out from the air outlet 8, and the flow value is read out from the air outlet flowmeter 4.
When the air inlet 7 of the air inlet flowmeter 1 is blocked, namely an air inlet passage of the device is blocked, a displayed value of the air outlet flowmeter is read, if the displayed value is basically 0, the sealing performance of the filter sealing device 2 can be judged to be good, and if the displayed value is not obviously reduced, the existence of air leakage of the filter sealing device 2 is indicated.
As shown in fig. 2, the air inlet end of the filter sealing device 2 is connected with a ventilation joint 5, the outer circumferential surface of the ventilation joint 5 is provided with a circle of grooves, and a sealing ring 6 is arranged in the grooves. When the ventilation joint 5 is screwed into the filter sealing device 2, the air tightness of the assembly surface is ensured under the action of the sealing ring 6, air leakage is avoided, and the plugging and unplugging of an operator are facilitated.
