Below in conjunction with accompanying drawing structure of the present utility model and operating position are further described:
Embodiment 1
A kind of pen automatic filling device, its structure are divided into slot 1, mozzle 2, air-pressure chamber 3, switch room 4,5 five parts of reservoir; In the funnelform slot 1 rubber seal ring 11 is set, in order to guarantee sealing, mozzle 2 is connected in pen slot 1 bottom, mozzle 2 lower ends are opened a side opening 21 and are communicated with switch room 4, mozzle is two ends and mid portion about in the of 2, and the part that is separately fixed at slot 1 bottom and switch room 4 preferably is provided with pin thread; Air-pressure chamber 3 is by outer cylinder 31 and rubber sliding plunger 7 airtight the forming that are positioned at it, there is a thin short duct outer cylinder upper end, the mozzle 2 of drawing from slot 1 therefrom passes, be fixed with rubber seal ring 32 between duct and the mozzle 2, there is fastening nut 33 its outside, constitutes closed system by rubber sliding plunger 7 in the outer cylinder; Be provided with spring 6 between fastening nut 33 and the slot 1; Switch room 4 is positioned at the cavity of rubber sliding plunger 7, central part at two ends is fixed with aforesaid mozzle 2 about it, top, switch room has a pore 41 and communicates with air-pressure chamber 3, and a valve rod 42 and valve 43 are arranged at the bottom, connects a small hose 8 under the valve port and feeds in the reservoir 5; The internal diameter of outer cylinder 31 lower ends is bigger than its top, and inwall is provided with negative thread, and is meshed as capping 52 with reservoir mouth pin thread, and pore 51 is arranged in the capping 52.It is shaft-like that valve rod 42 is round rib, and the upper end is a hollow ball, and the lower end is a valve joint 423, and valve joint top is hemispherical, and the bottom is reeded cone, and its diameter is greater than valve aperture.Valve port is also also recessed downwards to be hemisphere face shape, and both can agree with to guarantee airtight mutually; The buoyancy valve rod is except that the hemisphere place of valve joint 423, and remainder floats on valve rod or when falling, all is normally open with valve port.
During use, pen is inserted in the pen slot 1, contact sealing with rubber seal ring 11 after, press down and divide a word with a hyphen at the end of a line, spring between pen slot and outer cylinder is compressed and 7 times enforcement air-pressure chamber 3 volumes increases of drive rubber piston, cause air pressure to reduce and produce negative pressure, will pass through the air of the switch room of pore 41 connections with it,, also the ink in the reservoir is drawn in the switch room 4 by small hose and valve simultaneously in turn in the suction air-pressure chamber 3 together with the air in a slot that is communicated with the switch room and the pen capsule.Valve rod was at the drive float downward valve-off 43 of ball float when liquid level reach a certain height.A pen capsule, pen slot all are negative pressure state at this moment.Upwards mention the pen slot again, the spring of compression pops up, and exercises air-pressure chamber 3 volumes on the drive piston 7 and diminishes, and the air pressure increase returns to normal pressure gradually, the ink in the switch room 4 is pressed into the pen slot enters then in the pen capsule that is negative pressure state; The air that had meanwhile before sucked in the air-pressure chamber 3 enters in the switch room 4 by pore 41; By valve, the ink in the switch room enters a capsule again, and liquid level is descended, valve rod is exercised valve for 42 times and is opening, and at this moment, air can pass through valve 43, and enter in the reservoir through flexible pipe 8, finally enter in the atmosphere by the steam vent in the reservoir capping 52 51.The pen that is full of ink is extracted from the pen slot, and all the other inks in the inflow pen slot are back in the switch room under the gravity effect and flow back in the reservoir by valve and flexible pipe.Pen fills the whole process of ink to be finished at this point.
