Abstract
A suction device suitable to create a vacuum in containers particularly for the preservation of food in a vacuum, consisting of a casing formed by two coupled halves (4, 5) that contain an electric motor (7) that actuates a suction pump formed by a cylinder-piston unit (14, 15), by means of a reducer group formed by a pinion (17) force-fit onto the shaft (16) of the motor (7) and by a crown gear (19) having an eccentric (37) which actuates a connecting rod (23) connected to the piston (15). The device has at one end a holed tip (34) which can be pluged directly in the seating of the valve (3) that is provided on the container, so that it can be used with one hand only.
Claims19
A suction device for drawing a vacuum in a container (2) having a valve (3), comprising:
- a casing (4,5);
- an electric motor (7) having a shaft (16) and mounted in said casing;
- a suction pump in said casing having a cylinder with an inlet and a piston movable in said cylinder (14,15), said suction pump being mounted in said casing at a location space from said electric motor;
- a motor gear (17) force-fit onto said shaft;
- a crown gear (19) meshed with said motor gear and mounted for rotation in said casing between said motor and said pump, said crown gear including an eccentric (37) eccentrically movable when said motor gear rotates to rotate said crown gear;
- a connecting rod (23) operatively connected between said eccentric and said piston for reciprocal movement of said piston in said cylinder with rotation of said motor gear;
- and
- a hollow suction tip (34) adapted for engagement with the valve of the container, said tip being engaged with an end of the casing opposite from the motor and in communication with said inlet of said cylinder for drawing a vacuum from the container through the valve when the motor gear rotates.
A suction device according to claim 27, including a valve body (24) engaged with said cylinder and a diaphragm valve (25) engaged with said valve body for admitting air through said inlet, said terminal cap being fixed to said valve body.
