Description of the invention: [Technical field of the invention] The present invention relates to an atomizer structure, in particular to vibration of a component such as a piezoelectric material, so that the auxiliary vibration component receives vibration energy] The orifice sheet undulates and squeezes the liquid in the liquid storage chamber, and the eight holes are discharged from the nozzle hole to form a mist, so as to reduce the cost of the component, increase the fog, reduce the noise, and prolong the life of the atomizer. [Prior Art] The atomizers seen on the market are available in both pressure and mechanical oscillations. The former utilizes a large pressure difference, Chiang liquid atomization, although it can be the effect of the county, but its shortcomings are large particles, the need for machines with increased pressure, relatively large noise and high cost. The mechanically oscillating atomizer uses ultrasonic vibration to create a phenomenon of liquid contact with the liquid, which causes the fragmented liquid bubble to form small droplets, which produces an atomization effect. However, this atomization method has its disadvantages, for example: The power consumption is large, the fan is required to provide the direction of mist transmission, the volume is large, and the size of the atomized droplets is different. In the atomizer of the piezoelectric material, in addition to the above-mentioned method of ultrasonic atomization, there is also an atomizer used with the orifice sheet 9 (shown in FIGS. ea to 6b), which is used for the orifice plate. The 90 series has a dome-shaped projection 91, and the projection 91 has a plurality of injection holes 92. After the atomizer is added with the orifice sheet 90, the electrical energy used can be greatly reduced, and the particle size is controlled by the action of the aperture. At present, related patents or products can be roughly divided into two types. One is to use a piezoelectric material to vibrate the liquid to extrude the orifice sheet 90 to form a mist, and the other is to use a piezoelectric material to vibrate the orifice sheet 90 to make a liquid. Allow liquid to escape from spray 5 12721.28 hole 92 to form a mist. The former requires a relatively large amount of energy to generate vibration of the piezoelectric material for the droplets that generate small particles, so that the liquid can be extruded and atomized, which is slightly lower than the latter in terms of effectiveness. However, the cost ratio of the components of such an atomizer is the highest at the cost of the orifice sheet, which is about 30%. Therefore, if the use area of the orifice sheet can be reduced, and the atomization amount and the atomization effect are not affected, the availability can be improved, and the production cost is also reduced. Further, for the electroformed orifice sheet Because the material is mostly nickel and copper, its resonant frequency will be relatively low, causing a harsh α-sounding sound under certain vibration modes. If it is applied to the atomizer of medical purposes, the brake is not suitable for the patient to use, otherwise it will easily affect the patient's mood and affect the medical effect. As shown in Fig. 6a~叱, from the processing point of view, since the thickness of the electroformed orifice sheet 90 is very thin, about 3 〇#m, and then convex processing, the dome-shaped projection 91 is easy. Cracks are generated due to excessive stress, and part of the orifices 92 are also distorted to affect the atomization result. The relevant patents for the orifice sheet are as follows: 'US46.5567^ The product is relatively large, and its disadvantages are: 1• The production cost is high, including the formation of the orifice sheet and the processing of the protrusion. 2 · The orifice sheet is used in a relatively high amount. When L liquid is used up, there will be noise. (US5318179: The technical feature is that the orifice sheet has no convex design and the orifice sheet area is relatively large; the disadvantages are: 1 • The orifice sheet is expensive to use. 2. The atomization efficiency is limited. 3. When the liquid is exhausted There is noise. As can be seen from the above, the conventional atomizer has not been in an ideal state, and it is necessary to improve it. Based on the above reasons, the inventors actively seek to change the way of goodness, through numerous designs and experiments. SUMMARY OF THE INVENTION The purpose of the present invention is to provide a nebulizer structure which can reduce the cost of component components, increase the amount of atomization, reduce the noise, and prolong the service life. The embodiments are described in detail with reference to the drawings, so that the reviewing committee can further understand and understand the functions and features of the present invention. [Embodiment] As shown in Figures 1 to 3, The invention comprises: a casing 1 〇 for storing liquid; a bearing 20 for arranging related components; a vibration element 3 〇 for generating a vibration force; and an auxiliary feeding element 4 〇 for increasing vibration The amplitude effect, which may be a flat plate or with a beveled surface or a stepped surface; the inclined surface 4〇1 is intended to enlarge the orifice sheet of the auxiliary vibration element due to the oblique geometry when vibrating; an orifice sheet 50 has a plurality of orifices 51. In use, the vibration of the vibrating element 3 , causes the vibration energy to be transmitted to the auxiliary vibrating element 4Q, so that the auxiliary vibrating element vibrates reciprocally, and the squirting piece 50 undulates and squirts the liquid in the casing to discharge the liquid from the nozzle hole 51. The mist is formed. Hereinafter, the housing 10 is provided with a liquid storage chamber 11 for storing liquid; a water inlet I2 is provided for liquid to enter the liquid storage chamber 11; and an opening 13. The bearing member 20 is made of a soft material and can be To prevent water leakage, it is disposed on the opening 13 of the casing 10, and has a hole 21 in the center thereof. The vibration element 30 can be a piezoelectric material, covered by the bearing member 2〇 to avoid contact with the liquid, and has the electrode 31, the electrode 31 and The auxiliary vibration element 40 is provided with a hole 41. The peripheral edge is in contact with the vibration element 30, and is covered by the bearing member 20 and disposed on the bearing member 20. 1272128 The orifice plate 5〇, the number of nozzle holes 51 It is provided on the auxiliary vibration element 40. When the driving signal is transmitted to the electrode 31 via the wire 32 to cause the vibration element 3 to vibrate, its vibration energy is transmitted to the auxiliary vibration element 40, and the auxiliary vibration element 4 is reciprocated and vibrated. The orifice plate 50 is thus undulated. The liquid in the liquid storage chamber 11 causes the liquid to be discharged from the injection hole 51 to form a mist. As shown in Figs. 1 and 3, the auxiliary vibration element 40 vibrates in the liquid storage chamber 11. As shown in Fig. 2a, the present invention is another In one embodiment, the auxiliary vibration component 4 is disposed on the opening 11 of the housing 10, and has a hole 41. The vibration component 30 is disposed on the periphery of the auxiliary vibration component 40, and is provided with an electrode 31 connected to the wire 32. As shown in Fig. 2b, in another embodiment of the invention, the inclined surface 401 (protrusion) of the auxiliary vibration element 4 is disposed outside the liquid storage chamber. In order to achieve the purpose of carrying it, the liquid storage chamber 11 can be expanded in space, so that the liquid can be stored to a certain capacity, so that the operation of the atomizer can be independent, and it is convenient for the patient to take it around. In the case of long-term atomization, such as indoor humidity control or horticultural irrigation, the liquid supply source can be connected to the water inlet so that the atomizer can be operated for a long time. As shown in Fig. 4a, the edge of the orifice sheet 50 of the present invention is fixed to the auxiliary vibration element 40. Compared with the conventional orifice sheet 90 of Figs. 6a to 6b, the present invention assists the vibration element 4 The structure replaces the area of most of the orifice sheet 50, so the cost of the atomizer can be greatly reduced; and because the auxiliary vibration element 4 has a shape of a protrusion, the amplitude of the orifice sheet 5 can be increased, and the atomization can be improved. Quantity, and does not affect the effect of atomization. Alternatively, the auxiliary vibration element 40 and the orifice sheet 50 can be separately formed, and the 1272128 auxiliary vibration element 4 can be made of a general sheet metal die, and the orifice sheet 5 can be made of MEMS and assembled. Therefore, the area of the orifice sheet 50 (which is smaller than that of the method) is small, so that the production cost can be reduced. Further, the protruding portion falls on the auxiliary vibrating member 4, and the nozzle hole can be prevented from being twisted, and the thickness of the auxiliary vibrating member 4 can be changed to allow the material to be deformed to solve the stress problem caused by the over-processing. Moreover, since the auxiliary vibration element 40 is a relatively rigid material, the orifice sheet of the present invention has a high resonance frequency and a high structural strength, so that the problem of the sound can be solved and the service life can be prolonged. As shown in Figs. 5a to 5c, the edge of the hole 41 of the auxiliary vibration element 4 has a stepped section 41a, a trapezoidal section 4lb or an acute angle section 41c. As shown in FIGS. 5d to 5f, the auxiliary vibration element 4A has an arcuate convex portion 42a, a convex portion which is rotated by a small angle, or a convex portion 42c which is rotated by a small angle, due to the geometrical relationship of the inclined surface. The amplitude of the orifice sheet 5 at the auxiliary vibration element 4A is increased to increase the amount of atomization. Wirework As described above, the present invention has at least the following advantages: ^ Reduces the cost of use of the orifice sheet. 2. The amount of atomization is large. 3. Reduce noise generation. 4 ·Structural strength can extend the life of the atomizer. BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a perspective view of the present invention.
