rotating plate 322 towards the suction direction, negative pressure is generated in the airtight space between the movable ejector rod 323 and the end sealing sleeve 321, the end sealing sleeve 321 is driven to move towards the movable rotating plate 322, the light spring 314 is compressed in the process until the clamping block support column 317 penetrates into the clamping groove channel 316, the clamping block 318 is finally clamped into the clamping groove 319, when a group of clamping blocks 318 are clamped into the clamping groove 319, the elastic potential energy of the spring recovery deformation between the two corresponding pressure blocks 313 can be balanced, so that the negative pressure suction in the end sealing sleeve 321 can continuously suck the end sealing sleeve 321 towards the direction of the movable rotating plate 322, when the end sealing sleeve 321 moves towards the direction of the movable rotating plate 322, external air can enter the space of the dredging auxiliary pipe 310, which is close to one side of the end sealing sleeve 321, through the one-way air valve 311, internal pressure is balanced, until all clamping blocks 318 on the pressure blocks 313 are clamped into clamping grooves 319 on the side pressure blocks 313, all the light springs 314 are in compression states, the movable rotating plate 322 continuously rotates to drive the movable ejector rod 323 to rotate, the movable ejector rod 323 slides along the track of the movable ejector rod 315, when the movable ejector rod 3231 on the movable ejector rod 323 contacts the clamping blocks 318 which are clamped in the clamping grooves 319, the movable ejector rod 323 can eject the clamping blocks 318 out of the clamping groove 319, at this time, the pressure block 313 loses the limit function, the elastic force of all the light springs 314 can concentrate on a line to eject the end sealing sleeve 321, the side of the end sealing sleeve 321 close to the one-way air valve 311 can generate high pressure, positive pressure is generated on the side of the drainage tube 205 far away from the aspirator port 204 along the pipeline direction, in the process of restoring deformation of the light springs 314, the movable rotating plate 322 is pulled back towards the direction of the end sealing sleeve 321 through air pressure, so that high-strength negative pressure is generated on the side of the movable rotating plate 322 far away from the one-way air valve 311, under the combined action of negative pressure in the dredging auxiliary tube 310 and negative pressure suction caused by the external aspirator to the drainage tube 205, at this time, the negative pressure suction in the drainage tube 205 is far higher than that in normal suction operation, so that the blockage can be sucked out quickly, the negative pressure aspirator continues to operate, the whole course can be performed without any manual operation, the phenomenon that the drainage tube 205 is blocked is avoided by the operation patient without observing at any time, in the process of automatically cleaning the blocking object, when the gas-liquid on one side of the dredging auxiliary tube 310 flows towards the blocking ball 403, the blocking ball 403 can block the drainage channel, the phenomenon that the dredging process cannot be successfully completed is avoided, when the gas-liquid in the drainage tube 205 moves towards the direction away from the blocking ball 403, the internal gas-liquid flow can drive the blocking ball 403 to enter the blocking ball moving groove 402, the drainage channel is smooth, the drainage liquid in the drainage tube 205 can flow along the channel 404, the large-flow check valve main body 401, the blocking ball moving groove 402, the blocking ball 403 and the channel 404 are designed, and the check valve in the prior art is not adopted to ensure that the blocking object in the drainage process can not be blocked at the check valve, so that the design internal flowing space is large and the blocking is not easy to cause.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
