[0034] In this embodiment, the filter portion of the fire mask being tested is fixed by a snap ring 514 for designing docking requirements.

[0035] The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process. The specific operations are as follows.

[0036] Step (1), the device is driven by the controller 2. When the device is used for detection, the first hydraulic cylinder 42 in the lock tube 41 of the binding structure 4 is controlled to extend and drive, driving the rotating seat 43 to rise and separate from the lock tube 41, and then applying force to the first electric slide rail 46 on the cross arm 45. The strap 40 is rotated 90 degrees by the bearing on the rotating seat 43 through the support of the support arm 44, and the strap 40 is separated from the head cover 32 to prevent it from being blocked;

[0037] Step (2): open the fire mask to be tested, and put its head cover part on the head cover 32 in the first detection structure 3, and use the head cover 32 to imitate the human head; then pull the bottom end of the head, that is, the part located at the human neck, down to be located below the groove of the air guide column 31; then rotate the binding structure 4 to reset, and retract the first hydraulic cylinder 42 to embed the swivel seat 43 into the lock tube 41 for fixed position, at this time, the first electric slide 46 on the cross arm 45 drives the strap 40 to be located at the rear side of the head cover 32 and the air guide column 31; the strap 40 is supported by the binding column 49 to correspond to the groove; the first electric slide 46 can be driven to drive the bearing plate 47 to pass through the top of the head cover 32 to the front side of the head cover 32, at this time, the strap 40 presses the bottom of the mask tightly against the groove, and the second electric slide 48 and the binding column 49 are both located in front of the air guide column 31;

[0038] Step (3), drive the two second electric slide rails 48 to move the binding posts 49 relative to each other in an interlaced manner, so that the other end of the longer binding post 49 passes under the other end of the shorter binding post 49 to form an interlaced manner, and then drive the first driving slide rail to move the two binding posts 49 to the rear side of the air guide post 31 and interlace them again, thereby forming a cross and reciprocating winding to tightly bind the cover;

[0039] Step (4): embed the filter device of the mask into the retaining ring 514 on the column 512 in the clamping assembly 51, and drive the second hydraulic cylinder 513 on the support plate 511 to drive the other retaining ring 514 to descend for clamping and fixing; at the same time, drive the docking assembly 52 in the second detection structure 5, and use the third electric slide rail 521 to move the docking air drum 523 on the moving rod 522 to fit and seal the filter device of the mask, and close the fourth solenoid valve 524, so that the first detection structure 3 can be used for detection;

[0040] Step (5), when the first detection structure 3 is tested, the connection between the third solenoid valve 38 and the second solenoid valve 37 at the air extraction end of the liquid pump is closed by controlling the switches of the first solenoid valve 36, the second solenoid valve 37 and the third solenoid valve 38, and the connection between the first solenoid valve 36 and the second solenoid valve 37 is opened, so that the air pump 35 can extract air and blow it into the air guide column 31, and enter the mask through the air guide column 31 to inflate it to a certain air pressure, and then detect the internal pressure change through the internal air pressure detector 33 and transmit the data to the controller 2. If the pressure becomes smaller, there is a leak in the mask or there is a leak in the filter device;

[0041] Step (6), when the second detection structure 5 is detected, the third solenoid valve 38 is connected to the second solenoid valve 37, and the first solenoid valve 36 is connected to the second solenoid valve 37 and closed, so that the air in the air guide column 31 can be extracted by the air pump 35, and the fourth solenoid valve 524 is opened at the same time, and then the external air enters from the inlet of the electric heating box 53, passes through the fourth solenoid valve 524 and enters the docking air drum 523, and finally enters the mask from the filter device and is extracted and discharged by the air pump 35; at this time, essence or odorous liquid can be added to the electric heating box 53, and evaporated by the electric heating box 53 to produce odorous gas. If the filtering device is effective, the air detector 34 in the mask cannot detect it; if there is a leak in the filtering device, the fragrance cannot be completely filtered and detected by the air detector 34; by volatile fragrance instead of smoke detection, an effective detection effect can be obtained, and the filtering device will not be affected, causing damage to the filtering device of the fire mask and affecting its sale.

[0042] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
