In another embodiment of the present invention, further, the partition 25 includes a first plate 251 and a second plate 252, the first plate 251 is located above the second plate 252, the first plate 251 and the second plate 252 are rotationally connected, the first plate 251 and the second plate 252 both rotate with the central shaft 26, a torsion spring 255 is installed at a rotational connection position between the first plate 251 and the central shaft 26, and two ends of the torsion spring 255 are respectively connected with the first plate 251 and the central shaft 26.
Specifically, the torsion spring 255 is in a natural state in the first state, the first plate 251 and the second plate 252 are both disc-shaped, and the clamping groove 254 penetrates through the first plate 251 and extends into the second plate 252, so that the clamping block 236 penetrates through the first plate 251 and extends into the second plate 252, the external thread is arranged on the outer wall of the second plate 252, the air vent 253 penetrates through the first plate 251 and the second plate 252, a bearing is installed between the first plate 251 and the second plate 252, the outer ring of the bearing is connected with the first plate 251, the inner ring is connected with the second plate 252, steel balls are arranged between the inner ring and the outer ring, the steel balls are arranged to realize the rotational connection of the inner ring and the outer ring, namely the rotational connection of the first plate 251 and the second plate 252, in the prior art, the details are omitted, the first plate 251 is also rotationally connected with the center shaft 26 through the bearing, and the second plate 252 is rotationally connected with the center shaft 26 through the bearing;
In the first stroke, the first plate 251 and the second plate 252 are driven to synchronously rotate and descend by the rotation of the glass cylinder 23, the first plate 251 and the second plate 252 rotate on the central shaft 26, the central shaft 26 starts to stretch under the action of the telescopic section 261, the spring in the telescopic section 261 starts to stretch, at the moment, the torsion spring 255 between the first plate 251 and the central shaft 26 gradually contracts, and because the external threads are only arranged on the second plate 252, only the second plate 252 is screwed into the perforation 224 in the synchronous descending process of the first plate 251 and the second plate 252, the first plate 251 is positioned above the opening of the perforation 224 and does not enter the perforation 224, when the glass cylinder 23 reaches the second state, the clamping block 236 is separated from the clamping groove 254, after the rotation limit of the clamping block 236 is lost by the first plate 251, the torsion spring 255 starts to reset, and drives the first plate 251 to rotate on the second plate 252, and because the first plate 251 is rotationally connected with the second plate 252 through the bearing, the first plate 251 does not drive the second plate 251 to rotate, namely, the first plate 252 is kept to rotate on the perforation 224, and the second plate 252 is naturally reset until the second plate 252 is naturally idle;
In the second stroke, the first glass plate 231 and the second glass plate 232 in the second state are spliced again to form the glass tube 23, the spliced glass tube 23 is lapped on the lantern ring 222 again, the protruding block 234 is inserted into the inserting groove 223 again, the clamping block 236 also enters the clamping groove 254, then the staff drives the glass tube 23 to reversely rotate and drives the first plate 251 and the second plate 252 to reversely rotate, at the moment, the spring in the telescopic section 261 resets and pulls the first plate 251 and the second plate 252 to ascend, the second plate 252 gradually rotates out from the through hole 224, the reverse rotation of the first plate 251 drives the torsion spring 255 to gradually expand because the torsion spring 255 is reset to the natural state, and when the glass tube 23 is reset to the first state, the first plate 251 and the second plate 252 stop rotating, and the expanded state of the torsion spring 255 is kept between the first plate 251 and the center shaft 26;
When the respirator body 2 is used, when the top opening of the air hole 253 is blocked by silica gel particles, air fed into the glass cylinder 23 by the transformer cannot enter the oil cup 24, so that the air pressure in the glass cylinder 23 gradually increases, at the moment, the air pressure in the glass cylinder 23 excessively forces and presses the first plate 251 and the second plate 252 to descend, the middle shaft 26 is driven by the telescopic section 261 to stretch again, the spring in the telescopic section 261 stretches again, the descending of the first plate 251 and the second plate 252 gradually leaves the limiting ring 235 due to the fact that the limiting ring 235 and the clamping block 236 remain stationary, the clamping block 236 also gradually breaks away from the clamping groove 254, and as the air pressure in the glass cylinder 23 gradually increases, the first plate 251 and the second plate 252 continuously descend, and finally the clamping block 236 breaks away from the clamping groove 254, at the moment, the rotation limitation of the second plate 252 is relieved again, the breaking away of the clamping block 236 provides rotatable conditions for the first plate 251, 255 starts to reset, the first plate 251 is driven to rotate on the second plate 252, and the torsion spring 251 breaks away from the silica gel particles on the top opening of the first plate 253 in a rotating manner;
after the air holes 253 are opened, air in the glass cylinder 23 flows into the oil cup 24, air pressure in the glass cylinder 23 is reduced, the springs in the telescopic sections 261 drive the center shaft 26 to reset and shrink, the first plate 251 and the second plate 252 are driven to reset and rise, the second plate 252 is propped against the limiting ring 235 again, the clamping blocks 236 enter the clamping grooves 254 again, and the clamping blocks 236 limit the rotation of the second plate 252 again.
It should be noted that, in the present embodiment, the torsion spring 255 drives the second plate 252 to reset once and rotate for a set number of turns, so the clamping groove 254 on the second plate 252 is still located below the clamping block 236 after rotation, and the lifting of the second plate 252 still enables the clamping block 236 to be inserted into the clamping groove 254.
While certain exemplary embodiments of the present invention have been described above by way of illustration only, it will be apparent to those of ordinary skill in the art that modifications may be made to the described embodiments in various different ways without departing from the spirit and scope of the invention.
