The movable block 7 pulls the conical diaphragm 10 to suck air, and pulls the sealing plug 27 in the air inlet pipe 11 to move towards one side close to the contour groove 9, so that air can enter the contour groove 9 through the air inlet pipe 11, at the moment, the first connecting end 30 on the sealing plug 27 can be contacted with the second connecting end 31 and turn on the work indicator lamp 29, similarly, when the movable block 7 pushes the conical diaphragm 10 to compress air, the first connecting end 30 on the sealing plug 27 in the air outlet pipe 12 can be contacted with the second connecting end 31 and turn on the work indicator lamp 29, but when the sealing performance of the conical diaphragm 10 is deteriorated, the moving range of the sealing plug 27 in the air inlet pipe 11 and the air outlet pipe 12 is reduced, so that the first connecting end 30 cannot be contacted with the second connecting end 31 and turn on the work indicator lamp 29, and therefore, when the work indicator lamp 29 is in a normally closed state, the conical diaphragm 10 at the bottom end of the work indicator lamp 29 is damaged, therefore, the conical diaphragm 10 can be conveniently and accurately replaced in time, and the using effect of the compressor is further improved.

As an embodiment of the present invention, referring to fig. 2, 7 and 8, an annular top plate 32 is fixedly connected to a top end of each conical diaphragm 10, an annular bottom plate 33 is fixedly connected to a bottom end of each conical diaphragm 10, a plurality of fastening bolts 34 are inserted into a bottom wall of each annular top plate 32, a plurality of threaded holes matched with the fastening bolts 34 are formed in a top wall of an inner side of each groove 8, an annular connecting plate 35 matched with the annular bottom plate 33 is fixedly installed on an outer side wall of a bottom end of each movable block 7, a plurality of connecting screws 36 are fixedly installed on a bottom wall of each annular connecting plate 35, a plurality of screw holes matched with the connecting screws 36 are formed in each annular connecting plate 35, and a fastening nut 37 is threadedly connected to an outer side wall of a bottom end of each connecting screw 36.

A plurality of and toper diaphragm 10 mutually supported's access holes have been seted up jointly on drain pan 1 and the top shell 2, establish the outside to movable block 7 from the top cover of movable block 7 with annular bottom plate 33 through the access hole, use connecting screw 36 and fastening nut 37 to fix annular bottom plate 33 to movable block 7 on, then use fastening bolt 34 to fix annular roof 32 to the inside wall on recess 8 top, just can install toper diaphragm 10, the same reason, can be convenient dismantle toper diaphragm 10, can be convenient install the dismantlement to toper diaphragm 10, consequently, can be convenient change toper diaphragm 10 after the sealed variation of toper diaphragm 10, thereby the convenience that the compressor used has been promoted.

As an embodiment of the present invention, referring to fig. 2 and 10, a plurality of connecting grooves 38 are uniformly formed on the top wall of the lifting plate 3, the connecting grooves 38 are matched with the mounting shaft 6, the connecting grooves 38 are in one-to-one correspondence with the mounting shaft 6, a mounting groove 39 is formed in each mounting shaft 6, two mounting plates 40 are symmetrically and movably mounted in each mounting groove 39, a plurality of guide rods 41 matched with the mounting plates 40 are mounted in each mounting groove 39, a second spring 42 is wound on each guide rod 41, two ends of the second spring 42 are fixedly connected to the two mounting plates 40, a projection 43 is fixedly mounted on the outer side wall of the top end of each mounting plate 40, one end of each projection 43 extends to the outer side of the mounting shaft 6, a plurality of limiting blocks 44 are vertically mounted on the outer side wall of the bottom ends of the two mounting plates 40, and one end of each limiting block 44 extends to the outer side of the mounting shaft 6, all vertically be provided with a plurality of spacing grooves 45 that mutually support with stopper 44 on the inside wall of every spread groove 38, and spacing groove 45 and stopper 44 one-to-one.

Press two lugs 43 and drive two mounting panels 40 and remove and shrink stopper 44 to installation axle 6 in, just can be convenient reciprocate installation axle 6 and movable block 7, not hard up lug 43, second spring 42 promotes mounting panel 40 and removes and just can be with installation axle 6 and movable block 7 fixed mounting on lifter plate 3 in promoting stopper 44 to the spacing groove 45 that corresponds, move down earlier installation axle 6 and movable block 7 when changing toper diaphragm 10, thereby be convenient for establish the top of movable block 7 or pull down from the top of movable block 7 with toper diaphragm 10 cover, the change degree of difficulty of toper diaphragm 10 has been reduced, thereby further promoted the convenience that the compressor used.

The working principle is as follows: the driving motor drives the cam driving disc 5 to rotate so as to drive the connecting rod 4 to eccentrically rotate and drive the lifting plate 3 to move up and down, the lifting plate 3 can drive the movable block 7 and the conical diaphragm 10 to move down when moving down, at the moment, gas can enter the contour groove 9 and the conical diaphragm 10 through the exhaust pipe 13 and the air inlet pipe 11, and the lifting plate 3 can drive the movable block 7 and the conical diaphragm 10 to move up when moving up, so that the gas in the contour groove 9 and the conical diaphragm 10 can be compressed and discharged through the air outlet pipe 12 and the air outlet pipe 14, the gas can be continuously compressed by reciprocating in such a way, no part is directly abraded when the compressor works, and the air tightness is good; when the movable block 7 pulls the conical diaphragm 10 to move downwards to the maximum displacement position, the outer side wall of the conical diaphragm 10 is tightly attached to the inner side wall of the annular limiting plate, so that the conical diaphragm 10 can be prevented from being broken due to overlarge instantaneous deformation; when the lifting plate 3 moves downwards, the fixing rod 25 and the piston 24 are driven to move downwards and the cooling liquid in the annular pump 23 is extruded into the cooling tank 21 through the radiating pipe 26, so that the conical diaphragm 10 can be cooled, when the lifting plate 3 moves upwards, the fixing rod 25 and the piston 24 are driven to move upwards and the cooling liquid with the increased temperature is sucked into the radiating pipe 26 and the annular pump 23 from the cooling tank 21, so that the conical diaphragm 10 can be cooled continuously by reciprocating, and the aging speed of the conical diaphragm 10 is delayed; the movable block 7 pulls the conical diaphragm 10 to suck air, and pulls the sealing plug 27 in the air inlet pipe 11 to move towards one side close to the contour groove 9, so that air can enter the contour groove 9 through the air inlet pipe 11, at the moment, the first connecting end 30 on the sealing plug 27 can be contacted with the second connecting end 31 and turn on the work indicator lamp 29, similarly, when the movable block 7 pushes the conical diaphragm 10 to compress air, the first connecting end 30 on the sealing plug 27 in the air outlet pipe 12 can be contacted with the second connecting end 31 and turn on the work indicator lamp 29, but when the sealing performance of the conical diaphragm 10 is deteriorated, the moving range of the sealing plug 27 in the air inlet pipe 11 and the air outlet pipe 12 is reduced, so that the first connecting end 30 cannot be contacted with the second connecting end 31 and turn on the work indicator lamp 29, and therefore, when the work indicator lamp 29 is in a normally closed state, the conical diaphragm 10 at the bottom end of the work indicator lamp 29 is damaged, thereby facilitating timely and accurate replacement of the conical diaphragm 10.
