VACUUM EXTRACTOR

WIPO Patent Application WO/2013/055111

A1

The present invention provides a vacuum extractor comprising: a support cap (10) formed with a hard synthetic resin; a suction disc (20) comprising a coating layer (24) injection coated with an elastomer on the upper surface (22a) and the circumferential lateral side (22b) of a plate (22) for adsorption, and an adsorption layer (26) injection molded with an elastomer having a hardness lower than that of the coating layer in an overlapped manner on the circumferential lateral side and a part of the coating layer including the lower surface (22c) of the plate for adsorption, in which the suction disc is elastically deformed so as to be closely adhered on surface to be suctioned(W); a clip (30) assembled to the outer portion of the support cap; a push cap (40) which is hung to be combined to a connection support pipe (42) so as to allow the connection support pipe to push a protruded rod (21) of the suction disc penetrating the outside of the support cap so as to be exposed; and a coil spring (50) elastically interposed between the clip and the push cap. A guide groove (14) is cut correspondingly to the outer circumference of a through-hole of the support cap, and a guide protrusion (44) is protruded longitudinally over a predetermined section on the connection support pipe of the push cap, thereby providing stable high vacuum adsorptive force continuously irrespective of the degree or shape of the flatness of a surface to be suctioned or seasonal temperature changes.
