The utility model has the advantages of simple structure, novel design, convenient operation, beautiful appearance, no pollution and simple, rapid and clean ink-sucking process. Because the exterior of the fountain pen with an automatic ink reservoir can be designed into various shapes, the utility model can be used for writing tables, bureaus and desks.

Description

Automatic ink-sucking unit for pen

The utility model relates to the automatic blotter of a kind of pen.

The method that traditional pen blots is that fountain pen nib is put in the ink bottle, the storage China ink sebific duct of extruding pen afterbody is realized, from the ink bottle of outwarding winding to pulling out the cap for brush, back out the penholder blotting, at last pen is installed, cover ink bottle and need eight elemental motions altogether, pretty troublesome, simultaneously, owing to do not know what of bottle ink inside, ink often pollutes pen even finger.In order to solve the cumbersome and unclean of pen tradition blotting mode, people have invented a kind of pen blotter, as the disclosed CN1061748A of Chinese patent literature, CN2099674U, CN2124149U etc., changed the above-mentioned disadvantage of pen tradition blotting to a certain extent, integrate, but come with some shortcomings: performance does not reach requirement; Complex structure, poor practicability; Though the energy Automatic inking is can ink can overflow after extracting pen out; It is still very complicated to go up black process; Be difficult for making and installing.Just because of above-mentioned defective, on market, also at present and do not find to have automatic blotter launch.

The purpose of this utility model just provides a kind of perfect performance, the blotting process fast, simple, cleaning, the automatic blotter of pen simple in structure.

The technical solution of the utility model is: can cover that recess is equipped with intubate in the lower housing portion on ink bottle, the piston ring tube of band spring is equipped with at the step place in housing, block cover with holes is housed in its tubular, and stretch out housing and be connected with a mouth inserter, positioning convex is arranged on piston, top cover is housed on housing, the check valve of band spring is housed in the centre bore post of housing, on check valve, have and the friction tight back-up ring of housing, below housing, have the hole, have the hole on the barrel of piston ring tube, at piston ring tube and top cover, sealing ring is housed between the housing centre bore post and around the piston.

Describe the utility model in detail below in conjunction with the embodiment accompanying drawing.

At first accompanying drawing is described:

Fig. 1 represents structure chart of the present utility model, is original state figure;

State diagram when Fig. 2 represents blotting;

Referring to Fig. 1, during use, a mouth of pen is inserted a mouth inserter (9) and down extruding, a mouth is closely contacted with a mouth inserter (9), with isolate from outer air, piston ring tube (3) down moves, piston contacts with the interior step inwall of housing (1), because the effect of sealing ring (11), (12), (13), make and form a low-pressure chamber between top cover (2) and the piston ring tube (3), air in pen capsule and the piston ring tube (3) just enters in the air chamber by hole (20), (21), and the air of external environment condition can not enter this air chamber.Simultaneously, piston ring tube (3) is pressed into the air below it in ink bottle by hole (23), when block cover (4) touches the top of shell (1) soon, air in the pen capsule has found time to be flattened by atmosphere, this process is an exhaust process, pen continues down agent and presses, block cover (4) covers on the top of shell (1), its sidewall blocks the pore (21) on the piston ring tube (3), as shown in Figure 2, make in air chamber and the piston ring tube (3) to completely cut off, block cover (4) promotes to have left back-up ring (5) downwards with check valve (6) simultaneously, opened check valve (6), under the differential pressure action of low pressure in the pen capsule and ink bottle inner high voltage, ink is just along intubate (9), check valve (6), hole (20) enters in the pen capsule, and this process is the blotting process.Pen is extracted in pen holder (9) rapidly after suctioning water, and piston ring tube (3) moves in spring (7) effect down, and at first, check valve (6) moves again under spring (8) acts on and contacts and close with back-up ring (5).In this small moving, because block cover (4) still covers the top of housing (1), piston ring tube (3) still is in state of isolation with air chamber, ink can not enter in the air chamber, the interior residual small volume of ink of tube of having only piston ring tube (3), this is the starting stage that resets, piston ring tube (3) moves on continuing under the effect of spring (7), at this moment block cover (4) breaks away from housing (1) top, be communicated with air chamber by hole (21) in the tube of piston ring tube (3), the interior residual ink of piston ring tube (3) is along the hole (20) just, (21) be inhaled in the air chamber, this is a breathing process, air pressure in air chamber and atmospheric pressure balance, piston ring tube (3) moves on continuing, air chamber enters the process to extraneous exhaust, at this moment the residual ink that enters in the air chamber is long-pending to the air chamber bottom under the gravity effect, the just gas on top that air chamber is discharged in the process of exhaust, there is not ink, can not occur polluting, be that positioning convex on the piston is against on the top cover (2) after piston ring tube (3) resets and finishes, piston breaks away from the step wall in the housing (1), form through hole (22) with housing (1) inwall, ink is by this through hole (22), hole (20) flows in the housing (1), flows in the ink bottle by hole (23) again.

The outside of housing of the present utility model (1), top cover (2) and a mouth inserter (9) can be designed to various moulding, and is attractive in appearance, has appreciation.

The automatic blotter of the pen that the utility model provides is simple in structure, and modern design is easy to use, whole blotting process is simple, fast, polluting can not appear in cleaning, be fit to very much the use of the modern life, work, its outside can be designed to various moulding, and is attractive in appearance, have value of art appreciation, is widely used on desk, desk and the desk, both having can be used as a kind of stationery, is again a kind of artwork ornaments simultaneously.

Accompanying drawing has been represented a specific embodiments of the present utility model, according to embodiment shown in the drawings, mouth inserter (9) is made for rubber, be contained in the top of piston ring tube (3), tight fit has block cover (4) in the tube of piston ring tube (3), have hole (20), the piston portion of piston ring tube (3) is positioned at the step place of housing (1), positioning convex is arranged on the piston, around the endoporus and on the cylindrical sealing ring (13) is housed respectively, (12), top cover (2) is housed on the housing (1), sealing ring (11) is housed, the non-return valve (6) of band spring (8) is housed in the centre bore post of housing (1), is equipped with on non-return valve (6) and the friction tight back-up ring of housing (1) (5), the below of housing (1) has hole (23), intubate (10) is equipped with at indent middle part in housing (1) bottom, can put in the ink bottle, be spun on the ink bottle for screw thread can be used as ink bottle cover on every side, all parts can adopt plastic shaping.
