when air is discharged, the force-bearing block 501 can slide on the inner wall of the air outlet 201 due to the flow of high-pressure air, the force-bearing block 501 can drive the moving block 503 to move downwards under the sliding action of the sliding block 502 and the sliding groove 505 while moving downwards, the moving block 503 can generate two groups of effects after moving downwards, one of the two groups of effects is that the moving block 503 can drive the connecting rod 507 at the bottom end to move downwards, so that the second wedge 705 on one side of the connecting rod 507 moves downwards to extrude the first wedge 704, and the first wedge 704 can enable the second rubber plate 703 to move out of the air outlet 201 and move towards one side close to the sleeve 401 after being extruded; secondly, after the moving block 503 moves, the tooth wall 504 on the outer wall of the moving block drives the driven gear 601 to rotate, after the driven gear 601 rotates, the driven gear 602 rotates under the action of gear meshing, after the power gear 602 rotates, the driving gear 603 rotates under the action of a transmission turntable and a transmission belt, after the driving gear 603 rotates, the driving plate 604 moves inwards under the action of gear meshing, so that the driving plate 604 drives the moving rod 701 to move inwards, the moving rod 701 moves to drive the first rubber plate 702 to move towards one side close to the sleeve 401, at the moment, the gap between the sleeve 401 and the air outlet 201 is filled through the matching movement of the first rubber plate 702 and the second rubber plate 703, and the sealing performance of the sleeve 401 is further improved through the extrusion effect of the first rubber plate 702 on the sleeve 401, so that the occurrence of air leakage is avoided,
when admitting air, gas can get into inside compressor 1 through check valve 801 behind the entering air inlet 3, in this process, the air can pass through the case 802 of check valve 801, thereby make the impurity in the air filtered, the quality by compressed gas has been guaranteed, furthermore, gaseous flow can make dredge plate 803 rebound, consequently, dredge plate 803 can drive multiunit dredge cone 804 and shift out to case 802 top, be convenient for admit air, the back of stopping admitting air, pretension spring can make dredge plate 803 reset, dredge plate 803 can drive dredge cone 804 rebound this moment, make dredge cone 804 remove to the hole of case 802 in, realize the mediation effect to blockking up impurity in the hole of case 802, prevent that case 802 from blockking up, the condition of also having avoided air inlet 3 gas leakage to take place, the leak protection gas performance of compressor has further been promoted.
Although embodiments of the present invention have been shown and described, it is intended that the present invention should not be limited thereto, that the particular features, structures, materials or characteristics described may be combined in any suitable manner in any one or more embodiments or examples, and that modifications, substitutions, variations or the like, which are not inventive and may be made by those skilled in the art without departing from the principle and spirit of the present invention and without departing from the scope of the claims.
