させる構成にかわるものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a plastic hend for an inkjet printer or an inkjet recording device that prevents the ink fluid held in the hend from permeating to the outside and evaporating. This is an alternative to a structure that reduces this.

合が必要となり、製造工程が複雑となる欠点があった。Conventional inkjet printer heads are constructed using metal, glass, or ceramic materials.
Since the material has a very low permeability to liquids and gases, the ink fluid held inside the head permeates to the outside and is difficult to evaporate, allowing stable printing even if the head is left standing for a long period of time. There are advantages. However, in order to form channels and nozzles through which the ink fluid passes, the head requires chemical treatment, complicated etching, and high-temperature, high-pressure bonding of the plate material on which the Si shadow is formed by the etching and other plate materials. However, there was a drawback that the manufacturing process was complicated.

にする。FIG. 4 schematically shows a conventional plastic head for an inkjet printer. The plastic substrate 1 with grooves formed therein can be easily manufactured by injection molding. Said substrate 1
The plastic diaphragm 2 and the entire solvent are bonded together and the solvent is dried to form an ink flow path 3 and a nozzle 5 for ejecting ink droplets 4. - The pinigi oscillator 6 made of ferroelectric turtle material gold and the metal plate 7 are glued together, and the imaging plate 2 and the metal plate 7 are bonded together using an adhesive 8.
It is glued by. A thin film electrode 10 and a solder bump 10-1 for bonding are formed on the piezo vibrator 6J.The flow path 3 and nozzle 5 are completely filled with ink 9, and a metal plate is connected using a power supply 12 and 11 switches. 7
When a pressure is applied between the electrode 10 and the thin film electrode 10, the piezoelectric vibrator 6
shrinks, and since the vibrator 6 and the entire top plate 7 are firmly bonded, the vibrator 6 and the metal plate 7 are deformed into a concave shape, and at the same time, the plastic pickup plate 2 is deformed into a concave shape, and the ink 9 is The ink droplet 4 is instantly pushed out in the forward direction 1 of the hend.
3. Fire and print. Switch 1 after firing ink drop 4
1 is opened to release the deformation of the piezo vibrator B, and the deformation of the diaphragm 2 is completely released.At the same time, the insufficient amount of the inter 2 is supplied from the rear of the flow path 5 in the supply direction 14 so that the next printing can be performed. do.
第５図はインクを光てんし、ノズル部５−１をホルダー
１５に保持したゴムキャンプ１６で押えた状態を示す。FIG. 5 shows a state in which ink is injected and the nozzle portion 5-1 is held down by a rubber camp 16 held in a holder 15.

and the metal permeates through the brass tink diaphragm 2-1, each with gas 1

では発生が皆無であった。FIG. 6 shows the state in which the moisture in the ink 9-1 is scattered outside as a gas 17 for a long period of time. The ink shining inside the hend? -1 has less moisture, and the ink 9-
The aqueous solvent and dye dissolved in 1 increase in a degree and the viscosity also increases. At the same time, the same amount of ink as the water vapor 17 scattered outside is replenished from the rear of the hend 14-1, so the viscosity continues to rise, and the viscosity of the ink at the nozzle 5-2 becomes extremely thick, causing the rubber camp 16 -1 Even if the ink 9-1 is completely released, the ink 9-1 does not flow, making it impossible to print as an inkjet printer.゛Figure 7 is an example of preventing the permeation and scattering of water vapor in ink, in which the entire metal plate 7-2 is attached with one's finger to almost the entire surface of the brass tink diaphragm 2-2 to completely reduce the permeation and scattering of water vapor 17-2. It is something. However, since the thermal expansion coefficients of the plastic moving plate 2-2 and the metal plate 7-2 are largely different, the metal plate 7-2 is heat-cured and bonded to the plastic vibrating plate 2-2 using adhesive 8-1, and then cooled. As a result, the residual stress increases and comes into contact with the water-soluble organic agent dissolved in the ink 9-6, causing solvent stress cracking (solvent crank) 19i. Polysal 7-on resin is used for the brass tink diaphragm 2-2, and the metal plate 7-2Vc
When using 18-8 stainless steel sheet metal, the coefficient of thermal expansion of the former is 5.
．． 5 X 10-'/deg, the latter being about I X 10-'
'/deg, and after heating to about 12°C and curing and adhering both with adhesive, the Polysal 7-on resin imaging plate 2-2 has a bending residual stress of about 500 Kg/crA or more. The 14-agent stress cracking 19 occurs. According to experiments, the solvent crank 19 is made of metal plate 7.
-2 covers the entire surface of the photographing plate 2-2, the fourth
As shown in Figures 6 to 6, there was no occurrence of this phenomenon in an area comparable to that of the piezoelectric vibrator.

ことを目的とする。In the brass inkjet printer head according to the present invention, the flow channels and nozzles can be easily and easily formed by injection molding, and the grooved plastic plate and other plastic plates can be joined by solvent welding at low temperature and low pressure. The purpose is to be able to perform it very easily without requiring large-scale equipment.

A metal plate 7-3 and a piezo vibrator 6-1 are firmly attached one after another on a plastic diaphragm 2-3, covering a portion of the n-channel 6-1. A metal film 20 is completely coated with adhesive 21 on the part of the plastic photographic plate 2-3 that is not covered with the metal plate 7-6.
Adhesive using. Very little water vapor 17-3 in the ink passes through the metal film 20 and evaporates and scatters to the outside. There was little residual stress when the bond was broken, and there was no solvent crank as seen in Figure 4.

比べ１５倍以上厚いためである。FIG. 2 shows an example of the effects of the present invention. In experiments, the amount of evaporation is proportional to the time the head is left standing, and in the structure of Figure 5 and 61￥1, it becomes a straight line 22, and the rate of evaporation depends on the structure and size of the head to be manufactured, and is approximately 3X10-"g/*- Hr
Met. When the diaphragm was entirely covered with a metal plate as shown in FIG. 7, the amount of evaporation was a straight line 23, and the evaporation rate was about 9 or less compared to the cases shown in FIGS. 5 and 6. In the case of FIG. 1, the evaporation amount is a straight line 24, which is almost different from the straight line 23, indicating that the effect of the present invention is remarkable. Therefore, metal plate 7
It was found that the amount of water vapor in the ink (17°) scattered through the minute gap between the ink and the metal film 20 was so small that it could be ignored. In FIG. 1, a plastic substrate 1-
The reason why the amount of water vapor in the ink scattered from the plastic substrate 1-2 is small is because the plastic substrate 1-2 is more than 15 times thicker than the plastic substrate 2-3.

ッドを製造するために不可欠なものである。A material made of copper or the like having a thickness of 5 μm to 200 μm was used, and a vinyl acetate adhesive, silicone rubber, or chloroprene rubber adhesive was used. Not only the ink water vapor 17-3 that passes through the entire plastic photographing plate 2-3, but also the total emitted amount of the plastic substrate 1-2 is as follows. As mentioned above, by gluing a metal film using the soft adhesive of the present invention, ink evaporation Mk in the flow path of an inkjet printer head can be effectively reduced and the shelf life of the head can be extended. Not, but
It is essential for manufacturing a stable inkjet printer head by absorbing the thermal expansion and contraction of the plastic material that makes up the ink flow path.
