Abstract
A needle for ink injection device includes a needle block, one terminal of which is connected with the ink injection device, a needle bar, and a hollow cylindrical tube, the first terminal of which is connected with the needle block, and the second terminal of which is tilt sharpened and has a slope; the needle is characterized in that the wall of the needle bar is provided with at least one incision communicated with the internal cavity of the needle bar.
Description
Technical field
The utility model relates to a kind of ink-filling device syringe needle, particularly plays the ink-filling device syringe needle of machine print cartridge filling ink to inkjet printing.
Background technology
By widespread usage, one of assembly of its easy consumption is the ink-jet printer cartridge that inner filling has ink to ink-jet printer as a kind of reliable and effective printing tools.In producing the print cartridge process in enormous quantities, adopt ink-filling device can ink in print cartridge usually.Existing a kind of ink-filling device, this device utilizes syringe needle with the gas sucking-off in the ink-jet printer cartridge, after reaching predetermined negative pressure value, pours into the ink of scheduled volume again by syringe needle in ink-jet printer cartridge.In this process, syringe needle may need to penetrate the seal as classes such as plug, sponges.At present the common syringe needle A that uses as shown in Figure 1, one end 101 is inclination sharpening shape, has an oblique long opening 102, the cutting edge of tiltedly long opening 102 both sides is very sharp.Because seal is softer, so in the process of syringe needle A puncture through seal part, cut seal easily, and be cut the inner chamber that the seal bits that get off can enter shank 103 along oblique long opening 102, result in blockage, China ink is irritated in influence, can cause syringe needle A and ink-jet printer cartridge to scrap simultaneously when serious.
The utility model content
The purpose of this utility model provides a kind of anti-blocking ink-filling device syringe needle.
For achieving the above object, the technical scheme that the utility model provides is: the ink-filling device syringe needle comprises: needle stand, and an end links to each other with ink-filling device; Shank, the cylindrical tube of hollow, its first end is connected with needle stand, and second end is inclination sharpening shape and has a slope; Wherein, the shank wall is provided with the otch that at least one communicates with the shank inner chamber.
Ink-filling device syringe needle with said structure, the perforate that is located on the shank wall can guarantee shank inner chamber and outside being communicated with, and avoids syringe needle blocked.
Scheme is that otch is located on the shank wall of a relative side with the slope preferably.In the process of ink-filling device with the needle pierces seal, the slope of second end can apply the lateral compression power perpendicular to the shank direction to seal, squeeze sealing member, if otch is located on this side shank wall, seal might enter otch under the effect of elastic restoring force, stop up the ink-filling device syringe needle.Yet the shank wall of a relative side with the slope produces lateral compression power because of not being subjected to the slope, so seal can not stop up the ink-filling device syringe needle because of elastic restoring force enters shank along otch.

Fig. 3 is the partial enlarged drawing of Fig. 2;
Working state schematic representation when Fig. 4 is the utility model ink-filling device usefulness needle pierces seal.
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is elaborated.
The specific embodiment
In conjunction with referring to Fig. 2 and Fig. 3, ink-filling device comprises needle stand 1 and shank 2 with syringe needle B.
Needle stand 1 is made of plastics usually, and inside has a central through hole 11, and one end 12 links to each other with the ink-filling device (not shown), and the other end 13 links to each other with shank 2.
Shank 2 is a cylindrical tube, generally is steel.First end 21 of shank 2 can be inserted into the other end 13 of needle stand 1, bonds together with the other end 13, and this end has the opening 211 that is communicated with shank inner chamber 23, and its central through hole 11 by needle stand 1 is communicated with shank inner chamber 23 with ink-filling device.Second end 22 of shank 2 is inclination sharpening shape, has a slope 221.With the shank wall 24 of slope 221 relative sides on be provided with otch 241.Otch 241 and second end, 22 spaced apart segment distances, and extend suitable length along the length direction of shank 2.Otch 241 can be processed to form by cutting tool, grinding tool.Otch 241 can be one or more, is specifically decided by length in the print cartridge of shank 2 insertion plan filling China inks.In the present embodiment, the number of otch 241 is one.
Otch 241 also can be located at other position of shank wall 24, but being the best on the shank wall 24 that is located at a relative side with the slope, because of on the shank wall 24 of this side, seal is not subjected to the extruding of side direction, therefore can not enter otch 241 because of the elastic restoring force bounce-back.
In the present embodiment, second end 22 also is provided with opening 222, as shown in Figure 4, in the process of ink-filling device with syringe needle B puncture through seal part 3, the cutting edge of 221 both sides, slope cuts the seal bits that get off might enter shank inner chamber 23 along opening 222, but because of also be provided with otch 241 on shank wall 24, therefore can guarantee shank inner chamber 23 and extraneous being communicated with, ink can be injected in the print cartridge through this otch 241, has avoided the obstruction of ink-filling device with syringe needle.
Variation based on the utility model design is not limited in the foregoing description; also multiple variation can be arranged; as second end 22 can be sealing; shank inner chamber 23 only links to each other with the external world by otch 241; the seal bits that can avoid slope 221 both sides cutting edges to cut fully getting off this moment enter the shank inner chamber; prevent that effectively ink-filling device from stopping up with syringe needle, these simple structural changes still belong to the protection domain of the utility model requirement.
