Description of the invention (1) [Technical field to which the invention belongs] The present invention particularly relates to a micro-droplet generator capable of ensuring a more uniform and finer atomization quality. [Previous technology] The use of nebulizers is quite extensive due to the inhalation and inhalation of drugs due to the use of chemical drugs. As far as medical use is concerned, the general therapy methods are mainly divided into two types: injection and oral. > The main shot type is relatively fast, but it must bear the pain of skin and flesh, and it also needs the assistance of a syringe. As for oral drugs, it does not require a syringe and is more convenient to use, but its disadvantage is that most of the oral drugs need The problems caused by absorption through the digestive system are slow efficacy and possible damage to the system; injection and oral medications each have their own advantages and disadvantages, while nebulizer medications can have both advantages The advantages of both, without their disadvantages, will be the most popular method of medicine in the future. The medical nebulizer atomizes the medicine into gas. After inhaling the gas through the patient, the medicine will enter the body through the lungs of the human body to achieve the medical effect. In this process, the efficiency of absorbing drugs by the respiratory system will be better than that of the consumption system. It absorbs quickly, so it has the advantage of fast efficacy of the injection method. In addition, because it does not need to pierce the skin, it also has the advantage that the oral method can avoid the pain of the flesh. However, the current medical nebulizers, because the atomized particles are not fine enough, the inhaled medicine gas is mostly distributed in the larger trachea, and it is difficult to reach the end of the branch tube, so that the absorption efficiency of the human body is very poor, not to mention The purpose of in-vivo drug therapy is achieved through exhalation, so most of them are currently only applied to the treatment of respiratory diseases such as asthma; the currently available medical nebulizers are pressure type

Description of the invention (2) Two types of mechanical vibration type, pressure type atomizer uses a large pressure difference to atomize the liquid. Although the effect of large atomization can be obtained, it has large particles and needs to be The disadvantages of the pressure-increasing machinery and the relatively large noise, and in terms of medical needs, do not need such a large amount of atomization, but more attention to particle size, so pressure atomizers are gradually not suitable for medical purposes. In recent years, the medical atomizers are mainly mechanical shock type, and most of them use ultrasonic vibration generated by piezoelectric materials to atomize the liquid. However, this atomization method has large power consumption and atomization. Disadvantages of different particle sizes, the need to fan mist and large volume of the device; In order to improve its shortcomings, a small number of medical atomizers are used in addition to piezoelectric materials, in addition to the orifice plate, such as the first, As shown in Figure 2, it is US Pattent N 0.6, 6 2 9, 6 4 6, which is bonded to a piezoelectric material 2 with an adhesive at one end of the cantilever 1, and the other end of the cantilever 1 with an adhesive. A nozzle plate 3 is bonded. The nozzle plate 3 has a plurality of tapered holes 4. The liquid is discharged from the holes 4 after being atomized. The fan does not need to be blown to reduce electrical energy, and passes through the hole diameter of the holes 4. Restrictions allow the particle size to be controlled, but the piezoelectric material 2 and the nozzle plate 3 of the atomizer are adhered to the cantilever 1 with an adhesive to transmit vibration through the cantilever 4. The problems caused by it are as follows: 1 The electrical material and the orifice sheet are bonded to the cantilever, and the vibration of the piezoelectric material is Transmission through the cantilever to the nozzle plate. If the piezoelectric material and the nozzle plate are not well bonded to the cantilever, causing the slightest separation of the bonding surface, it will reduce the transmission of vibration energy and affect the vibration of the nozzle plate. The situation will affect the quality of the atomization. 2 · Because the piezoelectric material and the nozzle plate are respectively bonded to the two ends of the cantilever with an adhesive, 200539946 V.

Description of the invention (5) The vibration force and quality are transmitted in the formula (5). If you refer to 6 ', the liquid or medicinal liquid filling nozzle 1 3 6 is passed through the L 1 3 source, and then adjusted. The effect of the oscillating amplitude will cause the body or medicinal solution to be fully mixed with the electric film 1 3 3 during the reciprocating vibration. The plugging can be caused by the 1 3 5 plug hole. According to the atomization effect of the spray hole micro, 1 3 4 and the pressure of the atomization of the spray hole sheet are provided for the spray hole sheet 1 3 5 The atomization zone 1 3 will accumulate a certain amount of atomized micro particles, and other particles will help the atomization progress. The action frequency caused the microfluid to cause the falling parts to be damaged. Figure 7 shows that the atomization is at 1 mm, 'without opening', and the pulsed chip & its high 'also makes τ, chemical'. At the same time, 3 3 3 6 Exclusively, when the quality of the bow of 1 5 is atomized with this gentleness, it is more integrated. In addition, the generator group, full of small 6 channels, allows the synergy to heal this board at the time. In order to ensure%, it can also be partially replaced and renewed. In the present invention, within the action of the piezoelectric plate 1 3 3 ^ 13, the nozzle plate l35 'Therefore, the liquid or medicinal liquid system will not work under gravity. The nozzle hole 1 3 6 overflows. When the electric shock is turned on, the vibration is increased by the booster circuit. 1 3 3 is in complex vibration. The vibration causes the liquid, some larger particles or molecular clusters in the atomization zone 13 to be pressed into smaller monomers, which not only reduces the nozzle orifices ^ makes the atomized gas more uniform, but also helps the large table. The reciprocating vibration of the liquid in the atomizing zone 13 will tend to cavitation, which will cause f to form a droplet shape, and achieve uniform and fine atomization. At the same time, due to the soft ring pad, the connection will be on the nozzle plate 1 3 5 When the lower ring cushion is elastically deformed, a slightly deformed buffer space will be provided to allow the mist punching space to contain the atomized microparticles. The particles to be atomized = will be discharged from the spray holes. Larger: liquid, The atomization is performed again, and the erection of the two-hole plate 1 3 5 can also reduce the vibration and atomize the liquid at a lower frequency.
