Description
Technical Field
The invention relates to an atomization component, in particular to a laminated atomization sheet which comprises a vibration ring, a vibration ring and a micropore atomization sheet, wherein fine particles and liquid drops can be sprayed out of micropores on the micropore atomization sheet through high-frequency beating liquid surface of the micropore atomization sheet to form elegant atomization gas. Besides, the invention also relates to an atomizing device applying the laminated atomizing sheet.
Background
When axial excitation force is applied to the flat disc body, longitudinal waves are generated in the flat disc body, the particle vibration displacement direction is balanced with the axial direction, axial deformation is formed, and radial deformation can be formed due to the Poisson effect of elastic deformation. Particularly for the ultrasonic atomization sheet, the ultrasonic atomization sheet mainly utilizes self high-frequency vibration to complete atomization of liquid. As shown in fig. 1, the sectional structure of a conventional two-piece ultrasonic atomization plate is schematically illustrated, and the two-piece ultrasonic atomization plate includes a piezoelectric ceramic ring 1 having an inner ring hole and a metal microporous plate 2, wherein an outer edge of the metal microporous plate 2 is bonded to the piezoelectric ceramic ring 1, and a middle portion of the metal microporous plate 2 corresponds to the inner ring hole of the piezoelectric ceramic ring 1. The piezoceramic ring 1 comprises a piezoceramic layer 11 which is polarized in the thickness direction and is annular, and a positive electrode layer 12 and a counter electrode layer 13 which are respectively arranged on the front surface and the back surface of the piezoceramic layer 11. When an alternating signal is applied to the piezoelectric ceramic ring 1, the piezoelectric ceramic ring 1 periodically deforms in an axial stretching manner along with the change of voltage and simultaneously deforms in a radial stretching manner by utilizing the inverse piezoelectric effect of the piezoelectric ceramic material. Because the axial thickness of the piezoelectric ceramic ring 1 is far smaller than the outer diameter thereof, the radial expansion deformation amount thereof is far larger than the axial expansion deformation amount. The metal microporous sheet 2 is an elastic sheet with a plurality of micropores arranged in the middle. Under the drive of the piezoelectric ceramic ring 1 which is deformed in a radial stretching way, the outer edge of the metal micro-pore sheet 2 is also deformed in a stretching way, and the middle part of the metal micro-pore sheet 2 vibrates and beats the liquid surface up and down in the axial direction under the extrusion and stretching action of the outer edge, so that liquid drops are sprayed out from the micro-pores to form atomized gas. The transmission rate of the radial vibration energy between the piezoceramic ring 1 and the metal microporous sheet 2 decisively influences the axial amplitude of the metal microporous sheet 2 and the atomization effect.
Subsequently, three-piece ultrasonic atomizing sheets were marketed, for example, in utility model 201220287726.4 filed on 6/19/2012 by symphysis medical technology ltd, and relates to a droplet generating apparatus comprising a vibration piece provided with a first through hole, a connection piece provided with a second through hole, the vibration piece and the connection piece being joined together by stacking a joining material, and the first through hole and the second through hole being arranged in up-and-down correspondence. The oscillating sheet is a piezoelectric sheet. The connecting piece is a metal sheet, a plurality of side walls are arranged on the connecting piece, and the side walls face to each other and are mutually connected through a connecting material. The spray hole piece is fixed on the connecting piece, and a plurality of fine spray holes are formed in the area, corresponding to the first through hole and the second through hole, of the spray hole piece. Therefore, the structure that the side wall of the connecting sheet and the side wall of the oscillating sheet face each other is utilized, the joint area of the connecting sheet is increased, so that the bonding strength between the oscillating sheet and the connecting sheet is improved, and the radial vibration energy of the oscillating sheet can be effectively transmitted to the orifice plate through the connecting sheet. However, in fact, even with the above-described structure, the transmission rate of the radial vibration energy between the oscillating piece and the orifice piece is still not ideal and is yet to be further improved.
Disclosure of Invention
The plurality of side walls of the connecting piece of patent 201220287726.4 are spaced one-piece walls connected to the connecting piece only by the feet, and the body portion above the feet is engaged with the oscillating piece. Under the drive of the oscillating piece which vibrates in the radial direction, the side wall main body part swings left and right in the radial direction. At this time, the connecting piece does not become a stressed body of the side wall main body part which swings left and right in the radial direction, namely, the side wall main body part is basically difficult to contact and drive mass points on the connecting piece to displace in the radial direction, so that the radial vibration of the oscillating piece can be greatly consumed by the left and right swinging of the side wall main body part, and is only slightly transmitted to the connecting piece through the side wall foot part and then transmitted to the spray hole piece through the connecting piece. Therefore, the side wall is mainly used for positioning the oscillating piece and the connecting piece, the effect of transmitting radial vibration energy is very weak, the transmission rate of the radial vibration energy between the oscillating piece and the spray hole piece is low, and the axial amplitude of the spray hole piece is small. In addition, as can be seen from the drawings of patent 201220287726.4, a plurality of through holes are formed at the same time when the side walls are formed on the connecting piece. These through holes can become channels for the atomizing liquid to climb onto the conductive layer of the oscillating piece to damage the oscillating piece. Therefore, a sheet body for shielding the through hole is required to be additionally arranged, so that the load of the oscillating sheet is undoubtedly increased, the vibration energy transmission rate between the oscillating sheet and the spray hole sheet is further reduced, and the axial amplitude of the spray hole sheet is further reduced.
Aiming at the defects of the prior art, the invention aims to improve the radial vibration energy transfer rate between the vibration starting ring and the micro-pore atomizing sheet so as to improve the axial amplitude of the micro-pore atomizing sheet. In view of the above, the present invention provides a laminated atomizing sheet, which includes a vibration ring and a vibration ring stacked up and down and connected together, wherein the vibration ring has a first through hole, the vibration ring has a second through hole, and the first through hole and the second through hole correspond to each other up and down; the vibration ring is characterized in that a pit is arranged on the vibration ring, and the second through hole is formed in the bottom wall of the pit; still including arranging micropore atomizing piece on the pit, micropore atomizing piece is than the vibration ring is frivolous, a plurality of micropores have been arranged on the micropore atomizing piece, the micropore is located in the axial projection scope of second through-hole, not only on the axial direction, the outer fringe diapire of micropore atomizing piece with the hole diapire fixed connection of pit, in radial direction moreover, the outer fringe lateral wall of micropore atomizing piece with tight fit between the hole lateral wall of pit.
Wherein, it can link together through modes such as cementing or welding to start between ring and the vibration ring, works as like this start ring vibration and during radial flexible deformation, can drive vibration ring also radial flexible deformation, promptly start ring can transmit its radial vibration that has and can transmit vibration ring, certainly also can transmit its axial vibration energy that has for vibration ring. The vibration ring becomes a power source member that supplies mechanical vibration energy to the vibration ring. In one application, the oscillation starting ring comprises a piezoelectric ceramic layer, and a positive electrode layer and a negative electrode layer which are respectively arranged on the positive surface and the negative surface of the piezoelectric ceramic layer, and the oscillation starting ring can convert electric energy into mechanical vibration energy under the driving of an alternating signal.
The micropore atomization plate is lighter and thinner than the vibration ring, the above characteristics define that the micropore atomization plate is not only smaller in thickness than the vibration ring, but also smaller in mass than the vibration ring. Under the condition of equal mechanical vibration energy, the energy density of the micropore atomization sheet is greater than that of the vibration ring, so that the axial amplitude of the micropore atomization sheet is greater than that of the vibration ring.
Where the axial direction is a thickness direction of the vibration ring and the radial direction is a direction perpendicular to the axial direction, unless otherwise specified, the "axial direction" and the "radial direction" appearing herein are collectively defined as such.
In order to realize the fixed connection between the outer edge bottom wall of the microporous atomization sheet and the pit bottom wall of the pit, a further technical scheme can be that the outer edge bottom wall of the microporous atomization sheet is glued or welded on the pit bottom wall of the pit.
In order to realize the tight fit between the outer edge side wall of the micropore atomization sheet and the pit side wall of the pit, a further technical scheme can be that the outer edge side wall of the micropore atomization sheet is in contact with and presses against the pit side wall of the pit. In this way, the radial vibration energy on the pit side wall of the pit can be directly transmitted to the micropore atomization sheet, and the loss of the radial vibration energy in the transmission process can be reduced, but the requirement on the processing precision is extremely high, and unqualified products can be easily manufactured. Therefore, the invention further provides the following technical scheme that the outer diameter of the micropore atomization sheet is smaller than the inner diameter of the pit, and a filling layer is arranged in a gap between the outer edge side wall of the micropore atomization sheet and the pit side wall of the pit. Therefore, the micropore atomization sheet is convenient to mount on the concave pit, and the middle part of the micropore atomization sheet is prevented from bulging to one side due to the fact that the outer edge of the micropore atomization sheet is excessively extruded by the pit side wall of the concave pit under a static state, and further the axial amplitude of the middle part of the micropore atomization sheet is reduced. The filling layer can fill the gap between the outer edge side wall of the micropore atomization sheet and the pit side wall of the pit, so that the transmission of radial vibration energy between the outer edge side wall of the micropore atomization sheet and the pit side wall of the pit is enhanced. Further, the filling layer is an adhesive layer.
As for the formation process of the dimples, there are various processes as long as the radial vibration energy can be transmitted to the micro-pore atomizing sheet through the dimple side walls of the dimples. In one application, the concave pits may be formed by punching and bending, and when viewed in cross section, the vibration ring has a bent plate shape with a lower middle part and two higher parts, but the concave pits may be greatly deformed and have unstable sizes. In other applications, can also form after corroding the shallow layer material in vibration ring surface through chemical solution the pit, perhaps form in the casting through the cooperation of concave-convex mold core again the pit is formed to the casting the while of vibration ring is integrative, what above-mentioned two kinds of forming process formed the pit warp for a short time, and is dimensionally stable, the pit is in it is sunken to form the axial on the vibration ring the depressed area in the wall body of vibration ring just as if having amputated the partial surface shallow layer material of vibration ring is general, more is favorable to the transmission of radial vibration energy. In this case, the recess may also be designed in such a way that it is axially recessed into the wall of the vibration ring.
As regards the position of the placement of the pits on the vibrating ring, there are two alternatives: the concave pit is arranged on the outer side wall of the vibration ring, which is back to the vibration starting ring, correspondingly, the micropore atomization sheet is arranged on the outer side wall of the vibration ring, and the vibration starting ring is arranged on the inner side wall of the vibration ring; and secondly, the pit is arranged in orientation on the vibration ring on the inside wall of the vibration ring, thereby the outer fringe of micropore atomization piece is held in between vibration ring and the vibration ring, be favorable to strengthening like this the installation steadiness of micropore atomization piece optimizes kinetic energy transmission between vibration ring and the micropore atomization piece.

Simultaneously the outer fringe diapire of micropore atomizing piece with fixed connection between the hole diapire of pit can weaken the outer fringe of micropore atomizing piece is in the middle part of micropore atomizing piece is the axial vibration under the reverse drive, makes and transmits radial vibration energy on the micropore atomizing piece gathers the middle part more. And because the micropore atomization piece is lighter and thinner than the vibration ring, the energy density that the micropore atomization piece has is bigger than the vibration ring, and the micropore atomization piece middle part has than the axial amplitude that the vibration ring is big plays the effect of enlargiing the axial amplitude.
On this basis, because on radial direction, the outer fringe lateral wall of micropore atomizing piece with tight fit between the hole lateral wall of pit, like this, work as the vibration ring is in when the drive of ring that shakes is radial flexible deformation down, the hole lateral wall of pit also radially contracts thereupon, enlarges, correspondingly holds tightly or relaxs the outer fringe lateral wall of micropore atomizing piece, further increase the radial flexible deformation range of the outer fringe of micropore atomizing piece, and then the increase the axial amplitude at the middle part of micropore atomizing piece. In addition, the synchronism of the radial telescopic deformation of the outer edge bottom wall of the micropore atomization sheet and the pit bottom wall of the pit can be optimized, and the outer edge bottom wall of the micropore atomization sheet and the pit bottom wall of the pit are prevented from being subjected to overlarge radial dislocation in the radial telescopic deformation process to damage the fixed connection characteristic between the outer edge bottom wall and the pit bottom wall of the pit. Secondly, the concave pit can also radially position the micro-porous atomizing sheet, so that in the embodiment that the outer edge side wall of the micro-porous atomizing sheet and the pit side wall of the concave pit are fixedly connected together through a fixing agent such as adhesive or welding agent, the using amount of the fixing agent can be reduced, and therefore the load of the vibration starting ring and the loss of radial vibration energy on the fixing agent are reduced.
In conclusion, the pit is provided with and does benefit to the improvement the vibration ring with the transmissibility of radial vibration energy between the micropore atomizing piece has improved the ring that shakes with the transmissibility of radial vibration energy between the micropore atomizing piece improves the utilization ratio of the radial vibration energy of ring that shakes increases the axial amplitude at micropore atomizing piece middle part.
In order to further enlarge the axial amplitude of the middle part of the micropore atomization sheet, the following technical scheme can be adopted: micropore atomizing piece is the cap form and includes central authorities bellying and encircle central authorities bellying peripheral brim of a hat portion, the micropore is arranged on the central authorities bellying, the micropore atomizing piece passes through brim of a hat portion connects on the vibration ring.
The further technical scheme can also be that the oscillation starting ring comprises a piezoelectric ceramic layer, and a positive electrode layer and a negative electrode layer which are respectively arranged on the positive surface and the negative surface of the piezoelectric ceramic layer. Further, an auxiliary electrode layer is further provided on the piezoelectric ceramic layer, the auxiliary electrode layer extending from the front surface to the back surface of the piezoelectric ceramic layer, the auxiliary electrode layer being electrically isolated from the positive electrode layer but electrically connected to the negative electrode layer.

Each of the specific implementation details, structures and methods disclosed below are described in detail as being necessary, and in addition to the specific descriptions pertaining to equivalent or alternative embodiments, the various implementation details disclosed below may be used selectively or combined in one embodiment, even if not directly related or synergistic in functional terms.
The oscillation starting ring 1 comprises a piezoelectric ceramic layer 11, a positive electrode layer 12 and a negative electrode layer 13 which are respectively arranged on the front surface and the back surface of the piezoelectric ceramic layer 11, and an auxiliary electrode layer 14, wherein the auxiliary electrode layer 14 extends from the front surface to the back surface of the piezoelectric ceramic layer 11, the auxiliary electrode layer 14 is electrically isolated from the positive electrode layer 12 but is electrically connected with the negative electrode layer 13, and the oscillation starting ring 1 and the oscillation ring 3 are overlapped and connected together. By adjusting physical parameters such as materials and sizes of the vibration ring 1 and the vibration ring 3, the vibration ring 3 can be in resonance coupling with the vibration ring 1. Under the drive of an alternating signal, the oscillation starting ring 1 converts electric energy into radial oscillation energy and transmits the radial oscillation energy to the oscillation ring 3 in a resonance coupling mode. The vibration ring 3 is driven by the vibration starting ring 1 to radially expand and deform. The vibration ring 1 serves as a power source member for supplying mechanical vibration energy to the vibration ring 3. In other embodiments, the vibration ring 1 may be another member capable of generating radial vibration energy.
The vibration ring 3 is a metal ring, and the pit 31 is formed by etching away shallow material on the surface of the vibration ring 3 through a chemical solution, that is, the pit 31 is formed by etching. Of course, in other embodiments, the concave portion 31 may be integrally formed at the same time as the vibration ring 3 is cast by fitting a concave-convex core. The concave pits 31 formed by the two manufacturing processes are axially sunk into the wall body of the vibration ring 3, so that a sunk area is formed on the vibration ring 3 as if a part of superficial material of the surface of the vibration ring 3 is cut off, and the vibration ring is stable in size and small in deformation after being molded. Alternatively, as shown in fig. 5, the recess 31 ' is formed by press bending, and the vibrating ring 3 ' has a bent plate shape with a lower middle part and two higher parts when viewed in a cross section, but the recess 31 ' may be largely deformed and may be dimensionally unstable. The forming process of the concave pits 31 is various, and not limited to a series, as long as the radial vibration energy can be transmitted to the microporous atomization sheet 2 through the pit side walls 312 of the concave pits 31. Secondly, pit 31 arrange in the orientation of vibration ring 3 on the inside wall of ring 1 that shakes, thereby the outer fringe 21 of micropore atomizing piece 2 by the centre gripping in between vibration ring 3 and the ring 1 that shakes, be favorable to strengthening like this micropore atomizing piece 2's installation steadiness optimizes the kinetic energy transmission between vibration ring 3 and the micropore atomizing piece 2. Of course, in other embodiments, as shown in fig. 6, the concave pit 31 may also be disposed on the outer sidewall of the vibration ring 3 facing away from the vibration ring 1, in which case the microporous atomization sheet 2 is disposed on the outer sidewall of the vibration ring 3, and the vibration ring 1 is disposed on the inner sidewall of the vibration ring 3.
Wherein the micro-porous atomizing sheet 2 is thinner and lighter than the vibration ring 3, and the above characteristics define that the thickness H1 of the micro-porous atomizing sheet 2 is smaller than the thickness H2 of the vibration ring 3, and the mass of the micro-porous atomizing sheet 2 is also smaller than the mass of the vibration ring 3. With the same mechanical vibration energy, the energy density of the microporous atomization sheet 2 is greater than that of the vibration ring 3, so that the axial amplitude of the microporous atomization sheet 2 is greater than that of the vibration ring 3. In addition, the micropores 2210 of the micropore atomization sheet 2 are located within the axial projection range of the second through hole 30, so that the micropores 2210 communicate with the first through hole 10 and the second through hole 30, and the liquid for atomization can pass through the first through hole 10, be atomized by the micropores 2210, and be ejected from the second through hole 30.
In order to realize the fixed connection between the outer edge bottom wall 211 of the micro-porous atomizing sheet 2 and the pit bottom wall 311 of the pit 31, the outer edge bottom wall 211 of the micro-porous atomizing sheet 2 is glued or welded on the pit bottom wall 311 of the pit 31. In order to achieve a tight fit between the outer edge sidewall 212 of the micro-porous atomizing sheet 2 and the pit sidewall 312 of the pit 31, in other embodiments, the following technical solution may be selected, and the outer edge 21 sidewall of the micro-porous atomizing sheet 2 contacts and presses the pit sidewall 312 of the pit 31. In this way, the radial vibration energy on the pit side wall 312 of the pit 31 can be directly transmitted to the atomizing sheet 2, and the loss of the radial vibration energy during transmission is reduced, but the requirement on the processing precision is extremely high, and defective products are easily manufactured. Therefore, the present embodiment adopts the following technical solution, the outer diameter of the micro-porous atomizing sheet 2 is smaller than the inner diameter of the concave pit 31, and a filling layer (not shown in the figure) is arranged in the gap between the outer edge sidewall 212 of the micro-porous atomizing sheet 2 and the pit sidewall 312 of the concave pit 31. In this way, the micro-porous atomizing sheet 2 is conveniently mounted on the concave pit 31, and the middle part 22 of the micro-porous atomizing sheet 2 is prevented from bulging to one side due to the fact that the outer edge 21 of the micro-porous atomizing sheet 2 is excessively pressed by the pit side wall 312 of the concave pit 31 in a static state, and therefore the axial amplitude of the middle part 22 of the micro-porous atomizing sheet 2 is reduced. The filler layer is capable of filling the gap between the outer edge sidewall 212 of the microporous atomization sheet 2 and the pit sidewall 312 of the pit 31, thereby enhancing the transfer of radial vibrational energy therebetween. Further, the filling layer is an adhesive layer.
According to the technical scheme, compared with the prior art 201220287726.4, the beneficial technical effects of the invention are as follows: because on the axial direction, the outer fringe diapire 211 of micropore atomizing piece 2 with the hole diapire 311 fixed connection of pit 31, like this, work as vibration ring 3 is in when the drive of ring 1 that shakes is radial flexible deformation down, can drive the outer fringe 21 of micropore atomizing piece 2 is radial flexible deformation together, the middle part 22 of micropore atomizing piece 2 is vibration about the axial under the extrusion of outer fringe 21, tensile effect. Meanwhile, the fixed connection between the outer edge bottom wall 211 of the micropore atomization sheet 2 and the pit bottom wall 311 of the pit 31 can weaken the axial vibration of the outer edge 21 of the micropore atomization sheet 2 under the reverse traction of the middle part 22 of the micropore atomization sheet 2, so that the radial vibration transmitted to the micropore atomization sheet 2 can be more gathered to the middle part 22. In addition because micropore atomization piece 2 is than vibration ring 3 is frivolous, the energy density that micropore atomization piece 2 has is than vibration ring 3 is big, lets the middle part 22 of micropore atomization piece 2 have than the axial amplitude that vibration ring 3 is big plays the effect of enlargiing the axial amplitude.
On this basis, because in radial direction, outer fringe lateral wall 212 of micropore atomizing piece 2 with tight fit between the pit lateral wall 312 of pit 31, like this, when vibration ring 3 is in when the flexible deformation of radial under the drive of ring 1 that starts to vibrate, pit lateral wall 312 of pit 31 also radially contracts, enlarges along with it, correspondingly hugs closely or loosens outer fringe lateral wall 212 of micropore atomizing piece 2, further increases the flexible deformation range of radial of the outer fringe 21 of micropore atomizing piece 2, and then increases the axial amplitude of middle part 22 of micropore atomizing piece 2. In addition, the synchronism of the radial expansion deformation of the outer edge bottom wall 211 of the micro-porous atomizing sheet 2 and the pit bottom wall 311 of the pit 31 can be optimized, and the characteristic that the fixed connection between the outer edge bottom wall 211 of the micro-porous atomizing sheet 2 and the pit bottom wall 311 of the pit 31 is damaged due to overlarge radial dislocation in the radial expansion deformation process is prevented. Secondly, the concave pits 31 can also radially position the micro-porous atomizing plate 2, which is beneficial to reduce the amount of fixing agent such as adhesive or welding agent between the micro-porous atomizing plate 2 and the vibration ring 3, and reduce the load of the vibration ring 1 and the loss of radial vibration energy on the fixing agent.
In conclusion, pit 31 be provided with and do benefit to the improvement vibration ring 3 with the transmissibility of radial vibration energy between micropore atomizing piece 2, and then also be favorable to improving start vibration ring 1 with the transmissibility of radial vibration energy between micropore atomizing piece 2 improves start vibration ring 1's the utilization ratio of radial vibration energy, the increase micropore atomizing piece 2's the axial amplitude of middle part 22.
In order to further enlarge the axial amplitude of the central portion 22 of the microporous atomization sheet 2, the microporous atomization sheet 2 is in the shape of a cap including a central convex portion 221 and a brim portion 23 surrounding the periphery of the central convex portion 221. The micropores 2210 are disposed on the central protrusion 221, and the micropore atomization plate 2 is coupled to the vibration ring 3 through the brim portion 23. The inner diameter of the first through-hole 10 is larger than the inner diameter of the second through-hole 20, and the inner diameter of the second through-hole 20 is slightly larger than the outer diameter of the central boss 221. This allows more radial vibration energy to be accumulated in the central boss portion 221, and increases the axial amplitude of the central boss portion 221.
