POWDER AND LIQUID SUPPLY DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/204036
Kind Code:
A1
Abstract:
The present invention relates to a device for automatically and manually supplying toner to a toner cartridge, and the device comprises: a DC adaptor (100); a residual toner detection sensor (200); a control means (300); a toner container (400); an air pump (500) for pumping the toner of the toner container (400); a three-way valve (600) connected between the toner container (400) and the air pump (500) so as to supply or block air to the toner container (400); and a toner hose (700) for transferring the toner of the toner container (400) to a toner cartridge. Thus, the present invention has practical application by providing the remarkable advantages of: enabling a smooth supply of toner by the gravity of the toner without solidification due to the shape of the toner container, by optimizing an internal angle of a funnel so as to remove the solidification of unused toner in the toner container; easily supplying even a liquid material in addition to powdered toner; supplying the toner by a difference between the pressure of a toner bottle and the pressure of a toner cartridge inside a printer by supplying air to an air bag, and after the toner has been supplied, collecting toner remaining in a supply hose to the toner container by discharging the air of the expanded air bag in various stages; atomizing solidified toner by mixing the toner of the toner container, and supplying the toner under a fixed condition regardless of the residual amount of the toner container, through a control chip of the toner container; and also, disconnecting the toner container from the outside so as to prevent a supply line for connecting the toner container and the toner cartridge from being contaminated by coming in contact with contaminated air and to prevent the solidification of the toner inside the cartridge.
