An inkjet printing device includes at least one ink cartridge, at least one ink pipe, at least one print head, an ink refill mechanism, and a pump module. The ink refill mechanism includes at least one transfer channel. After the ink refill mechanism is enabled and the at least one transfer channel is in an open status, in response to a suction generated by the pump module, the air within the at least one print head is ejected out through the at least one transfer channel, and the ink within the at least one ink cartridge is transferred to the at least one print head through the at least one ink pipe. |

1. An inkjet printing device, comprising:
a first ink cartridge for storing a first ink; a second ink cartridge for storing a second ink; a first ink pipe connected with said first ink cartridge, wherein said first ink is allowed to be transferred through said first ink pipe; a second ink pipe connected with said second ink cartridge, wherein said second ink is allowed to be transferred through said second ink pipe; a first print head connected with said first ink pipe, and comprising a first ink chamber, a first nozzle and a first vent; a second print head connected with said second ink pipe, and comprising a second ink chamber, a second nozzle and a second vent; an ink refill mechanism disposed under said first print head and said second print head, wherein when said ink refill mechanism is connected with said first vent and said second vent, said first ink within said first ink cartridge and said second ink within said second ink cartridge are allowed to be transferred to said first ink chamber and said second ink chamber through said first ink pipe and said second ink pipe, respectively, wherein said ink refill mechanism comprises:
a channel plate comprising a first transfer channel corresponding to said first vent and a second transfer channel corresponding to said second vent, wherein said first transfer channel and said second transfer channel are parallel with said channel plate, said first transfer channel has a first channel exit perpendicular to said channel plate, and said second transfer channel has a second channel exit perpendicular to said channel plate;a first switching module connected with said first channel exit and said second channel exit for controlling open/close statues of said first transfer channel and said second transfer channel; andan exhaust pipe disposed under said first channel exit and said second channel exit, and located near said first channel exit and said second channel exit, wherein when said first transfer channel or said second transfer channel is in said open status, an air within said first ink chamber or said second ink chamber is allowed to be transferred through said exhaust pipe; and a pump module connected with said exhaust pipe for generating a suction force, wherein said air within said first ink chamber is sucked by said pump module in response to said suction force when said first transfer channel is in said open status, or said air within said second ink chamber is sucked by said pump module in response to said suction force when said second transfer channel is in said open status, wherein said pump module comprises:
a power pump for generating said suction force;a suction pipe connected with said power pump;a discharge pipe connected with said power pump, wherein after said first ink is transferred through said power pump in response to said suction force, said first ink is further transferred through said discharge pipe;a storage element connected with said discharge pipe, wherein after said first ink is transferred through said discharge pipe, said first ink is stored within said storage element; anda coupling element arranged between said suction pipe and said exhaust pipe and said first duct, and connected with said suction pipe, said exhaust pipe and said first duct, wherein said coupling element comprises:
an outlet located at a first sidewall of said coupling element and connected with said suction pipe;a first inlet located at a second sidewall of said coupling element and connected with said exhaust pipe, wherein said air within said first ink chamber is introduced into said coupling element through said first inlet and transferred to said suction pipe through said outlet; anda second inlet located at said second sidewall of said coupling element, located beside said first inlet, and connected with said first duct, wherein said first ink is introduced into said coupling element through said second inlet and transferred to said suction pipe through said outlet; and a nozzle cleaning mechanism, wherein said nozzle cleaning mechanism is located beside said ink refill mechanism and connected with said pump module, wherein when said nozzle cleaning mechanism is connected with said first nozzle, in response to said suction force generated by said pump module, a clogged condition of said first nozzle is eliminated by said nozzle cleaning mechanism, wherein said nozzle cleaning mechanism comprises:
a first duct connected with said pump module, wherein said first ink within said first ink cartridge is allowed to be transferred to said pump module through said first duct; anda second switching module located near said exhaust pipe and said first duct for controlling open/close statues of said first duct and said exhaust pipe, wherein when said exhaust pipe or said first duct is in said open status, in response to said suction force generated by said pump module, said air within said first ink chamber, said air within said second ink chamber or said first ink is transferred to said pump module. |
