Definitions

the present invention refers to a suction device for creating a vacuum inside containers, such as basins, glasses and the like, of the kind used to preserve perishable products and in particular foodstuff.
the suction device comprises a vacuum pump, a motor for actuating said pump and control systems, all placed inside a single device designed to be placed on a table, as well as a detachable push rod, connected to said vacuum pump by a coil tube, suitable to couple to a valve element generally provided on the cover of foodstuff containers, to link the inside of the container to the vacuum pump when the device is actuated.
suction devices used to create a vacuum inside bags or containers such as food basins or the like are already known.
This device is fed by batteries, which recharge when the device is placed on its base.
This system has some limitations, mainly due to the fact that, since the device must be easy to handle, also with one hand only and therefore small-sized, it must necessarily have a limited power, as well as limited is the life of the batteries feeding the motor.
the present invention falls into this sector, by proposing a suction device suitable to create a vacuum inside containers, in particular for foods, capable of overcoming the aforesaid limitations.
the present invention provides for a suction device consisting of an apparatus to be placed on a table, inside of which the suction devices, the motor and the different control systems, and a push rod, connected to the suction devices through a coil tube, suitable to couple with a valve installed on the container, inside of which the vacuum must be created, are installed.
the manoeuvrable part of the device i.e. the push rod
the body of the device which is designed to be placed on the table, can have such size as to contain motor and suction means having also relatively high power.
the suction device consists of a device indicated as a whole with reference number 1, provided with a base 2 to be placed on a flat surface and which contains the suction systems, the motor and the control systems, as well as a push rod indicated with reference number 3, connected to the suction devices by means of a flexible coil tube 4, which push rod can be separated from the body of the device to be coupled to a valve provided on the containers wherein the vacuum must be created.
the push rod is provided with an air access consisting of a couple of coaxial tubes 28 and 29, which partially penetrate one inside the other, in such a way as to cause the air inflow to have a winding course, thus dropping the air humidity, which concentrates in the chamber 30 inside the push rod. Said push rod may be easily removed to be drained and cleaned.
a grid 5 enables a certain flux of air circulating inside the device, which is provided on a side with a switch 6 and an indicator 7, for example of a LED kind, which signals when the device is working and when the degree of vacuum has been reached.
crankcase 27 On the base 2, with damper means 26 in between, a crankcase 27 is fitted as a support of an electric motor 8, which actuates the suction devices placed inside the crankcase.
crankcase is closed at its lower part by a wall 31, so that the pump is placed in a completely closed environment, in order to decrease the noiseness of the device.
a pinion 10 On the shaft 9 of the motor 8, a pinion 10 is fitted, which by means of a toothed belt 11 actuates a cog-wheel 12 on which an eccentric 13 is mounted.
the shaft 9 is fitted on bearing rolls 32, while the connecting-rod 14 is mounted on an eccentric pin with a bronze connecting-rod 33 in between, in order to reduce noise and friction.
a sheet shutter 17 is fitted, which, by closing and opening, connects the inside of the cylinder 16 to a duct 18 provided on a grid 19, which tightens the sheet 17 against the cylinder 16.
the coil tube 4 which ends, at the opposite side, with the push rod 3, is connected to the joint 18.
a bypass 20 branches off, to which a pressure sensor, which is not shown by the figures, is connected, capable of checking when the desired degree of vacuum is reached.
This sensor generates signals, which are transmitted to a known electronic circuit, also not shown in figure 1, which when the set value is reached, actuates a LED 21 of the LED signaller 7, to inform the operator that the operation is concluded.
a second joint 34 is installed, which by means of a tube preferably made of silicone, not shown, connects the air outlet of the cylinder 16 to the inside of the chamber, which remains comprised inside the crankcase 17.
This solution allows to dramatically reduce the noise deriving from the compression and expansion of the air inside the cylinder.
the device In its upper part, the device is shaped in such a way as to create a seating 22 to lodge the push rod 3 when this is not in use.
a microswitch 23 is installed, which actuates the device when the push rod is raised and stops its functioning when it is stored.
the push rod 3 is also provided with an end 24 made of soft material, for example rubber or the like, shaped in such a way as to match with the valve provided on the vacuum food container.
the device is made ready to use by actuating the general switch 6, through which the eclectic supply is transmitted to the circuit of the motor 8, to which a microswitch 23 is installed, to the LED system 7, which controls the turning-on of a first LED to signal that the device is ready for use and to the other devices as the control electronic board and so forth.
the operator raises the push rod 3, by removing it from the seating 22 and thus causing the microswitch 23 to turn, enabling the feeding of the motor 8.
the motor by means of the cog-wheels 10 and 12 and the eccentric 13, actuates the piston 15 that, by opening and closing the sheet shutter 17, sucks air from the duct 18, to which the push rod 3 is connected though the flexible coil tube 4.
the control board controls the turning on of the LED 21 to signal that the operation is concluded.
the suction device according to the invention offers an improved practicality of use as compared to the known devices thanks to the fact that it provides for a push rod separated from the device, allows to use duly powered motor and suction systems, offering at the same time the lightness and the easy manoeuvrability of the device (the push rod 3) which can be actuated manually.
