Description of the invention: [Technical field to which the invention pertains] + The present invention relates to a back pressure adjusting mechanism in an ink g, and more particularly to a back pressure adjusting mechanism applied to an ink jet printer ink cartridge. [Prior Art] Ink is fine, and is an indispensable consumable for any inkjet printer. If there is no pressure in the craftsmanship, the road towel of the wealth, especially in the cargo hold of the plane in the high coffee, when the glaze is obviously lower than the ground, the ink will automatically seep out of the craftsman's to get the goods to the destination. After that, it becomes a product that f is unacceptable. This - clear reading, the degree of inferiority of the South, will also lead to gambling (10) increased pressure, if there is no pressure on the design, Qing Lai may also appear bleeding. = Printing technology has been developed so far, controlling the inkjet head to release ink droplets to the squirt type can be roughly divided into two major mainstreams. It is a thermal bubble type (10) job. 1.Jet technology. The principle of its operation is to use a heating resistor (thin fllm r^) to heat part of the ink to extrude the ink and pass it through the ship. Another__Electric_fine_She) The conductivity of the quartz crystal for body growth and solidification. After the energization, the current causes the quartz crystal to generate a mouth-to-mouth frequency and pushes the ink out of the nozzle. This is because when the pressure of the material _=====1260278, the pressure in the leeches changes. If the negative pressure change in the ink smith cannot be effectively adjusted, the smear of the ink droplets will be affected, and it may be The situation of creating the ink by the m-go method is produced. ... Therefore, it is necessary to have its unique negative pressure adjustment design to adjust the pressure inside the ink cartridge in response to changes in conditions such as pressure, temperature and ink volume, so that the ink cartridge maintains a stable supply of ink and avoids ink leakage or ink supply. Produced to maintain good quality. At present, in the thermal bubble inkjet printing technology, the currently used ink cartridges, ink supply and negative pressure adjustment methods can be further divided into two categories: 1. Designed by materials with porous properties as ink reservoirs: This type of ink cartridges The ink supply structure and method are mainly filled with a porous material into the ink cartridge as an ink storage material, for example, foamed cotton, and a gas supply hole and an air passage are opened on the ink cartridge, and the material characteristics and siphon of the foamed cotton are utilized. The phenomenon is matched with one hole and air passage to achieve ink storage, stable ink supply and avoiding ink leakage. However, this design has the following shortcomings: A · Insufficient soil water · Because the ink storage material is in the ink There is a fixed space, and because it has many pores, the ink cannot be completely filled, but only about 85% of the ink volume of the ink storage material can be filled to avoid ink leakage, so that the ink storage capacity of the ink cartridge is large. Remaining ·Because the ink storage material used is a porous material, each of the water and the loss of water will cause the air to have a porous characteristic of the ink storage material, thereby causing: Water residue; soil 7 C· easy to produce blockages: because the ink storage material can be roughly divided into two types of foaming materials and fibers, both of which may cause blockages such as staple fibers, and then block the inkjet head. This in turn affects the quality of the print. Moreover, the foamed cotton is a soft body which is easy to change the shape due to the external force of the mouth. Therefore, it is obviously more expensive to be placed in the ink cartridge and is difficult to complete. Therefore, this type of (4) ink leg flip has many shortcomings to be changed. Second, the dragon adjustment mechanism: _ air bag, air bag with shrapnel purse with yellow and pressure plate and other back pressure adjustment method: -1 = 7 in order to improve the use of hole characteristics The ink storage volume caused by the ink storage material is reduced by the design of the air bag, the air bag and the elastic piece or the air bag with the spring and the pressure plate to adjust the internal movement of the e. The operation of the air bag is in the black box. When the ink force changes, the atmospheric pressure changes the volume of the air bag to correspond to the change of the two inks. The pressure is used to match the machine's bag to make it suitable for turning the throttle.敎 For 'soil and avoiding the situation of ink leakage or ink supply, 'the design of the device has the next point: $^5 weeks is (four) = the amount of bag is too small, depending on the size of the larger ring i brother It is easy to cause ink leakage when changing; ^ B: The current back ugly device is often used to prevent gas in the air bag for the purpose of increasing the capacity of the bag and its ventilation problem. Need a lot of complicated processing methods; ', clothing' to go through C: the traditional dragon Since the mechanism component parts due to too many parts and assembling accuracy between demanding percent. On the other hand, Chuan = that is, the material of the institution said that the low rate of miscellaneousness of the target ^ caused the production cost of the ink to increase. What's more, the ink is repaired; ^The mechanism's "high positional accuracy requirements, so that the ink production cost of the ink is = 槿3曰ΐ: a back pressure that can improve the above-mentioned conventional technology, the knot mechanism, It is urgent for us to solve the problem.土乃即械1260278 [Summary] The fine object is done, 11 is made of _ the surface of the _ has a rugged texture structure, (10) into a gas guiding device, =::, the relative position of the air bag and the vent hole The end of the bend:::, clothing, _, precision and production cost of the higher surface 33 Ming device, can be used for 掬 s 2, and the wrong use of this hair ^ for the air bag, increase the capacity of the air bag The magnitude of the air pressure adjustment also increases. &Into the above purpose 'this case - a more general implementation of the form of - kind of back _ :: structure 'is applicable to - ink _, to adjust the heart" "Hai ink system has - qi ι / ΓΓ The structure of 4 is disposed in the casing, and the disc is connected with the filler to adjust the inner part of the shaft (4); - the elastic element, the one side of the casing is opposite to the top, and the other side wall is The air bag is connected to the force, and the _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ The system has a texture structure with irregularities, forming a phase of the guidance of the station, the small road, the intersection of the Wenlu and the mouth of the mouth, the gas can be used to pass the bag and the air hole of the air hole. , water _ gas • the outside world is used to wither the pressure inside the shell. 1260278 According to the concept of the case, the towel should be mixed with the singer &; 糸 糸 — 线圈 线圈 线圈 线圈 线圈 线圈 线圈 线圈 线圈 线圈 线圈 线圈 线圈 线圈 线圈 线圈 线圈 线圈 线圈 线圈 线圈 线圈 线圈 线圈The towel presses the force of the plate material to press the air bag.

Therefore, in this embodiment, the U-shaped/clothing (as shown in the third figure) is placed in the casing 11 to present a moon-shaped raft that is enhanced by the external contact force. Force, and the air bag 12 has a bend m and its inner surface device is rugged to find the structure 122 (as shown in the fourth figure) to form a guide structure 122 with a gas-concave rugged structure. So that the gas can smoothly pass through the bend 121 of the bag 1260278 bag 12, and reach the air bag 12 and the air supply hole 112, so that the air bag 12 will not be smashed into two parts to make the gas two Adhesion to the contact surface, thereby improving the problem of difficult gas conduction, and allowing the gas = smooth running like (four) rigid force, kiss is like == ^ effect. In addition, the state of the state of the fine grasp of the fine == set in the guide to prevent the more legal, but increased # miscellaneous, the accuracy is not easy to control and the production costs are higher. And the wire is twisted with -= two gas 112. The two opposite contact faces of the two parts of the wire can be directly attached to the inside of the air bag 12 ==::: convex, the shape of the knot is not limited The structure of the ridge structure of the ridge is 122 or other auxiliary shape, semi-circular shape, and the shape is not limited to the U-shaped knot shown in this embodiment. The inner surface is provided with a rugged and curved portion, and the device 'is usable for allowing the gas to smoothly pass through the folded garment, and the mouth structure, which are all protected by the present invention. Please refer to the figure - 'When the ink money 1 first city product, the details will have a first face' so that the ink will not leak ink, then the air bag 12 will be slightly reversed by 14 lines _ yellow 13 squeeze The air bag 12 will be closely attached to the back side. Please refer to the second figure, which is the structure of the structure shown in the first figure, and the structure diagram of the day and the day is used. When the ink inside the ink tank m is consumed by printing, the ink is tilted by 1 (four) (four) and the pressure is forced to the outside. The air is smothered by the vent hole 112 of the wrecked body 12 1260278 11 into the air bag 12, and the flat plate M drilled in the air bag 12 is also shameful, and the air bag is sturdy, and the original structure is tightly wound by the uneven structure of the surface to make the coil 箦D Deformation, and by the smooth passage of the air bag 12 to form the air guiding device, the opposite end 124 of the connection of the outside air can be reached, because the air reaches the bag and the air hole 112, so - come, good 12 / It will not be easy to guide the placket due to the folding of the 121. It does not need to go through the complex parts. For example, the double air bag structure, and then, there is no need to add any air conduction problems. 1 The capacity of the twisting bag 12 and the absence of the unevenness of the adjustment mechanism of the present invention are due to the fact that the surface of the air bag is provided with irregularities f, and with the air guiding device, the gas can be smoothly passed through the folding of the air bag === = The opposite end of the junction makes the air bag not adhere to the six or two opposite contact surfaces and is not easy to conduct air, which can increase the problem of air bag valley/9 law gas conduction, and the whole back pressure adjustment mechanism process Simple, achievable, increased throughput and improved product yield, * and reduced part count, simplifying the assembly process' can effectively shorten assembly time and reduce production costs. Therefore, the Xiao pressure-touching mechanism of this case is of great industrial value, and loves to apply according to law.
