There is the interval distance between first filter screen 90 and the drawing liquid pipe 83, and the drawing liquid pipe 83 outside has set up division board 85 along axial interval, and division board 85 cover is located drawing liquid pipe 83 and is located between the upper and lower adjacent feed liquor hole 84, is connected with elastic component 86 between the adjacent division board 85, and division board 85 side edge and first filter screen 90 are close to drawing liquid pipe 83 one side cooperation setting.
The extractor tube 83 has a boss 87 fixed to the outer side of the bottom, and the bottom-most partition plate 85 is supported by the boss 87.
When the pump body 82 pumps liquid through the liquid pumping pipe 83, a plurality of division plates 85 can slide relatively axially and extrude the elastic component 86 under the action of liquid flow, the gliding division plates 85 can be to the inboard plastic of the first filter screen 90 of encircleing on the one hand, guarantee the form of first filter screen 90, avoid first filter screen 90 to receive the hydraulic pressure to take place deformation to influence filtering capability, on the other hand, shake takes place when division plates 85 extrude the elastic component 86, shake can transmit to first filter screen 90, be favorable to promoting the tiny piece in the outside of first filter screen 90 to drop, the filter effect of first filter screen 90 has been improved, prevent to block up.
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.
