Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims.
- Referring to FIGS. 1 to 9, the invention relates to a liquid extruding device, which is composed of a
base 10, asoft washer 20, anextruding stick 30 and amotor 40. Gaps would occur when the ovalcentral post 31 of the extrudingstick 30 rotates inside thehole 21 of thesoft washer 20. By way of the engagement of the ovalcentral post 31 with thegyroidal groove 22 of thehole 21, gyroidal narrow gaps would form between thecentral post 31 and thegyroidal groove 22, the oval cross-section of which appear a gryoidal distribution. Besides, the periphery of the ovalcentral post 31 is greater than the diameter of thehole 21 of thesoft washer 20 such that the tolerance of the preferred interferential cooperation is 0.2 mm. While excessive interferential cooperation would run down the axis power of themotor 40, small interferential cooperation would require the bias of the axis of themotor 40 be controlled extremely precise, and subsequently the process and assembly should be precisely. As such, it is important to determine an appropriate interferential cooperation degree. Accordingly, thesoft washer 20 is served as a sustainer, the ovalcentral post 31 is served as a rotator, such that as the non-circle post rotates, the gyroidal gap on the hole wall can generate a extruding effect due to the change of the space, thereby the liquid exists in the gap would move and exchange position to form a pump-like effect to drive the liquid. - Referring to
FIG. 2 , thebase 10 has ahollow portion 12 which is provided withpositioning grooves 11 around the wall. Thebase 10 is provided with aninlet end 13 at one side going through thehollow portion 12, anoutlet 14 at the bottom going through the hollow portion, and retainingholes 15 at the other end. Inside of thehollow portion 12 of thebase 10 is provided with asoft washer 20 which is peripherally provided withpositioning ribs 23 corresponding to thepositioning grooves 11, thereby thesoft washer 20 can be positioned in thehollow portion 12 of thebase 10. Thepositioning grooves 11 provided on the wall of thehollow portion 12 share a circle with thecorresponding positioning ribs 23 provided around thesoft washer 20, such that the force generated by the firm engagement thereof can be evenly born. Meanwhile, the positioning grooves 11 and thepositioning ribs 23 are replaceable by matching non-smooth walls. Inside thesoft washer 20 is provided with ahole 21, which has an oval cross-section, goes through theinlet end 13 andoutlet end 14, and interiorly provided with a gyroidal groove 22 (as shown inFIGS. 5 and 6 ). - Referring to
FIGS. 7 and 9 , theextruding stick 30 is provided at one side acentral post 31, which has an oval cross-section (as shown inFIG. 9 ) and can be inserted into thehole 21 of thesoft washer 20. The outer diameter of thecentral post 31 of the extrudingstick 30 is greater than the diameter of thehole 21 of thesoft washer 20. The preferred tolerance of their interferential cooperation is 0.2 mm, such that thecentral post 31 and thehole 21 can interferentially cooperate with each other. The other side of the extrudingstick 30 is provided with aengaging hole 32 for connectedly receiving theaxis 41 of themotor 40. - Further referring to
FIGS. 2 and 3 , between the extrudingstick 30 and themotor 40 is provided with aspacer 34, which is provided withscrew holes 35 corresponding to theretaining holes 15 on thebase 10. By way ofscrews 80, thespacer 34 can be fastened to one end of thebase 10. An O-ring 33 is further provided between thespacer 34 and the extrudingstick 30. Accordingly, a novel liquid extruding device is accomplished. - As shown in
FIGS. 3 and 4 , when themotor 40 drives itsaxis 41 to rotate, theextruding stick 30 would be driven as well, subsequently thecentral post 31 having an oval cross-section would rotate. As thecentral post 31 rotates, thesoft wash 20 would stay still since it is held in thehollow portion 12 of thebase 10. Therefore, thecentral post 31 of the extrudingstick 30 would rotate inside thehole 21 of thesoft washer 20 and generate gaps. Rotation of thecentral post 31 inside of thesoft washer 20 would result in gaps on thegyroidal groove 22; the gaps exchange position in one direction to form an effect of extruding and driving liquid, thereby the liquid will flow in theinlet end 13 and out theoutlet end 14. - Concluded above, the liquid extruding device according to the invention can efficiently improve the disadvantages existing the prior art. Rotation of the
central post 31 inside of thesoft washer 20 would result in gaps on thegyroidal groove 22; the gaps exchange position in one direction to form an effect of extruding and driving liquid. - It will be understood that each of the elements described above, or two or more together may also find a useful application in other types of methods differing from the type described above.
- While certain novel features of this invention have been shown and described and are pointed out in the annexed claim, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the spirit of the present invention.
