Abstract

The utility model discloses a constant-pressure air-pressure pen, which comprises a pen mouth, a pen body, an ink storage device and a connecting guide pipe. The constant-pressure air-pressure pen ischaracterized in that the ink storage device comprises an ink storage device container and an ink storage device cover, wherein the ink storage device cover is in tight screw connection with the ink storage device container, the top end of the ink storage device cover is equipped with an ink outlet through hole and a constant-pressure through hole, the outer end of the ink outlet through hole is tightly connected with the pen body through the connecting guide pipe while the inner end is tightly connected with an ink suction guide pipe, and the outer end of the constant-pressure through hole istightly connected with a constant-pressure source through the connecting guide pipe. The constant-pressure air-pressure pen is simple in structure, convenient in use and low in using cost without manually pressurizing, the ink storage device can be added with ink repeatedly and reused, thereby reducing material consumption cost by 30-50% compared with a disposable ink storage device, avoiding using disposable materials, and having environmental protection property and fine economic efficiency.

Description

Constant pressure type air pressure pen

Technical field

The utility model relates to a kind of air pressure pen that is applicable to the mechanical high-speed plotter of advertisement, building, rag trade, relates in particular to a kind of constant pressure type air pressure pen that can keep constant operating pressure in the pen.

Background technology

The existing conventional pen that is applied to the mechanical high-speed plotter exists China ink not enough and cause the unsharp problem of lines of drawing, patent ZL200520114336.7 discloses a kind of air pressure pen and has overcome such defective, can realize the svelteness that the high speed machine plotter is drawn, do not break, still, the technical scheme that this patent adopts is the disposable accumulator that goes out, and when first the use, also need artificial pressurization, thereby troublesome poeration, need constantly to change disposable accumulator, use cost height.

The utility model content

The purpose of this utility model is, overcomes the above-mentioned defective of prior art, and a kind of artificial pressurization that do not need is provided, and can be recycled the constant pressure type air pressure pen that use cost is low.

For realizing described purpose, the technical scheme that the utility model provides is as follows: construct a kind of constant pressure type air pressure pen, comprise a mouth, handwriting, accumulator, connecting duct, described accumulator comprise that accumulator holds body, hold the body accumulator lid that closely is spirally connected with accumulator; Described accumulator caping end is provided with out black through hole, constant voltage through hole, and described ink hole outer end closely is connected with handwriting by connecting duct, and its inner closely is connected with the blotting conduit, and described constant voltage through hole outer end closely is connected with constant pressure source by connecting duct.

Be provided with sealing ring between described accumulator appearance body top and the accumulator cover cavity top.

Describedly go out black through hole, the constant voltage through hole is equipped with the sealed fitting device.

Described accumulator inner chamber maintains constant operating pressure, and this operating pressure makes and goes out black connecting duct by accumulator, and handwriting keeps China ink smooth between the mouth inner chamber, and a mouth goes out China ink evenly, does not break.

The utility model usefulness is, simple in structure, easy to use, do not need artificial pressurization, accumulator can add ink repeatedly, recycles, consumables cost can be reduced to disposable accumulator cost 30～50%, use cost is low, has avoided the use medical disposable material, has the feature of environmental protection and good economic benefit.

Description of drawings

Be further described below in conjunction with accompanying drawing and preferred embodiment concrete technical scheme with regard to a kind of constant pressure type air pressure pen described in the utility model.

Fig. 1 is a structural representation of the present utility model.

The specific embodiment

Consult constant pressure type air pressure pen shown in Figure 1, comprise a mouth 1, handwriting 2, accumulator 3, connecting duct 4, described accumulator 3 comprise that accumulator holds body 32, hold the body accumulator lid 34 that closely is spirally connected with accumulator; Described accumulator covers 34 tops and is provided with out black through hole 342, constant voltage through hole 344, described ink hole 342 outer ends closely are connected with handwriting 2 by connecting duct 4, its the inner closely is connected with blotting conduit 346, and described constant voltage through hole 344 outer ends closely are connected with constant pressure source by connecting duct.Described accumulator appearance body 32 tops and accumulator cover between the 34 inner chamber tops and are provided with sealing ring 36.Describedly go out black through hole 342, constant voltage through hole 344 is respectively equipped with sealed fitting device 346,348.

Described accumulator 3 inner chambers maintain constant operating pressure, and this operating pressure makes and goes out black connecting duct 4 by accumulator 3, and handwriting 2 keeps China ink smooth between a mouth 1 inner chamber, and a mouth 1 goes out China ink evenly, does not break.

Above-described only is principle of the present utility model and preferred embodiment.Should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model principle, can also make some modification and improvement, also should be considered as belonging to protection domain of the present utility model.
