Description

Technical Field

[0001] The present invention particularly relates to an ultrasonic electronic cigarette. Background Art

[0002] The existing ultrasonic electronic cigarette includes a shell, in which an ultrasonic atomization sheet, an oil guide mechanism and an oil tank are arranged. The oil tank is connected to the atomization surface of the ultrasonic atomization sheet through the oil guide mechanism. The smoke oil or other smoke-producing substances in the oil tank are guided to the atomization surface of the ultrasonic atomization sheet through the oil guide mechanism. The smoke oil or other smoke-producing substances generate smoke under the high-frequency atomization action of the ultrasonic atomization sheet for users to inhale.

[0003] In existing ultrasonic electronic cigarettes, the ultrasonic atomizer sheets are all in the shape of discs, which include a disc-shaped piezoelectric substrate, a surface electrode fixed on the surface of one side of the piezoelectric substrate, and a driving electrode fixed on the surface of the other side of the piezoelectric substrate. When working, the surface electrode and the driving electrode are respectively connected to the two poles of the power supply, and the ultrasonic atomizer sheet can perform high-frequency atomization.

[0004] Since the disc-shaped ultrasonic atomizer needs to be fixed by a cylindrical fixing sleeve, and the fixing sleeve surrounds and fixes the ultrasonic atomizer along the circumference of the ultrasonic atomizer, the circumference of the ultrasonic atomizer is fixed, thus limiting the high-frequency working amplitude of the ultrasonic atomizer, affecting the atomization effect, and the amount of smoke is small. At the same time, since the atomization effect of the disc-shaped ultrasonic atomizer is relatively poor, in order to improve the atomization effect, the diameter of the ultrasonic atomizer is generally larger, resulting in a larger size of the ultrasonic electronic cigarette. Summary of the invention

[0005] The object of the present invention is to provide an improved ultrasonic electronic cigarette with good atomization effect, large smoke volume and small size in view of the above-mentioned deficiencies in the prior art.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0007] An ultrasonic electronic cigarette comprises a shell, in which a fixing seat, an ultrasonic atomizing sheet, an oil guide mechanism and an oil tank are arranged, the ultrasonic atomizing sheet is fixed by the fixing seat, and the oil tank is connected with the atomizing surface of the ultrasonic atomizing sheet through the oil guide mechanism; the ultrasonic atomizing sheet comprises a sheet-like piezoelectric substrate, a surface electrode fixedly arranged on the surface of one side of the piezoelectric substrate, and a driving electrode fixedly arranged on the surface of the other side of the piezoelectric substrate, and its structural feature is that the piezoelectric substrate is in the shape of an elongated strip; the piezoelectric substrate is composed of an interconnected atomizing section and a fixing section, the fixing section is fixed by the fixing seat, and the atomizing section is suspended.

[0008] With the above structure, since the piezoelectric matrix is ​​in the shape of a long strip, a long strip ultrasonic atomizer sheet is formed. The ultrasonic atomizer sheet is composed of two sections, a fixed section and an atomizing section. When in use, the fixed section of the ultrasonic atomizer sheet is clamped and fixed by a fixing seat, and the atomizing section of the ultrasonic atomizer sheet is suspended. During the atomization process, since the fixed section is clamped and fixed by the fixing seat, the amplitude of the fixed section is relatively weak. The atomizing section of the ultrasonic atomizer sheet is suspended in the air, without anything to restrain it, so the amplitude is relatively large, the atomization effect is good, and the amount of smoke is large. Since the ultrasonic atomizer sheet in the present invention has a good atomization effect, a smaller-sized ultrasonic atomizer sheet can achieve a larger smoke volume effect, and the size of the ultrasonic atomizer sheet and the ultrasonic electronic cigarette is relatively small.

[0009] Furthermore, a limiting plate is provided in the shell, the limiting plate is located on one side of the ultrasonic atomization sheet, and the oil guide mechanism is located on the other side of the ultrasonic atomization sheet; there is a gap between the limiting plate and the atomization section of the ultrasonic atomization sheet.

[0010] The gap can prevent the ultrasonic atomizer from hindering the amplitude change of the atomization section during operation, and prevent the heat generated during operation of the ultrasonic atomizer from being taken away by the limiting plate and affecting the increase of the smoke temperature.

[0011] Furthermore, an atomizing outer sleeve and an atomizing inner sleeve are arranged in the shell, the oil guide mechanism is cup-shaped, the side wall of the oil guide mechanism is sleeved between the atomizing outer sleeve and the atomizing inner sleeve, and the outer bottom surface of the oil guide mechanism contacts the atomizing surface of the ultrasonic atomizing sheet.

[0012] Furthermore, a partition is provided in the atomizing inner sleeve, which divides the atomizing inner sleeve into a first cavity and a second cavity, the first cavity is communicated with the oil tank, and the second cavity is communicated with the inner bottom surface of the oil guide mechanism; an oil groove connecting the oil tank and the oil guide mechanism is provided on the side wall of the atomizing inner sleeve corresponding to the first cavity.

[0013] Furthermore, a suction nozzle is connected to the top of the shell, a ventilation pipe is arranged in the shell, one end of the ventilation pipe is connected to the air inlet, and the other end of the ventilation pipe is connected to the second cavity, and an air hole connecting the second cavity and the suction nozzle is opened on the side wall of the oil guide mechanism.

[0014] The inner sleeve of the atomizer is divided into two cavities by a partition. The side wall of the first cavity is provided with an oil groove, and the smoke oil in the oil tank is connected to the oil guide structure through the oil groove. The second cavity is a cavity connected to the atomization surface of the ultrasonic atomizer. The smoke generated by ultrasonic atomization is stored in the second cavity. The air enters the second cavity from the air inlet through the ventilation pipe, fully taking away the smoke in the second cavity, and enters the user's mouth through the suction nozzle.

[0015] As a preferred embodiment, the length direction of the ultrasonic atomization sheet is parallel to the length direction of the electronic cigarette, which is conducive to the miniaturization of the ultrasonic electronic cigarette.

[0016] Furthermore, it also includes a spring, one end of the spring abuts against the outer wall of the atomizing inner sleeve, and the other end of the spring abuts against the inner bottom surface of the oil guide mechanism.

[0017] The spring is used to achieve reliable contact between the oil guide mechanism and the ultrasonic atomization sheet.

[0018] As a preferred embodiment, one side surface of the piezoelectric substrate is fully covered by the surface electrode, and the central area of ​​the other side surface of the piezoelectric substrate is covered by the driving electrode, and the ratio of the surface electrode area to the driving electrode area is a:b.

[0019] As another preferred embodiment, the surface electrode is fixedly arranged on the surface of one side of the atomization section, and the driving electrode is fixedly arranged on the surface of the other side of the atomization section.

[0020] Furthermore, the surface electrode and the driving electrode are both rectangular; or, the surface electrode and the driving electrode are both circular.

[0021] As a preferred embodiment, one side surface of the atomization section is fully covered by the surface electrode, and the central area of ​​the other side surface of the atomization section is covered by the driving electrode, and the ratio of the surface electrode area to the driving electrode area is a:b, wherein a is greater than b.

[0022] As another preferred embodiment, one side surface of the atomization section is composed of a covered area with a surface electrode fixedly provided and an exposed area without a surface electrode fixedly provided, the covered area and the exposed area are arranged along the length direction of the atomization section, and the covered area is closer to the fixed section than the exposed area; the ratio of the surface electrode area to the driving electrode area is a:b, wherein a is greater than b.

[0023] Due to the above structure, there is a distance between the surface electrode and the end of the atomization section, so that the heat generated by the ultrasonic atomization sheet during the atomization process can diffuse to both ends. Therefore, the heat dissipation speed is fast and the atomization effect is better, preventing the atomization section from breaking due to high temperature during operation and extending the service life of the ultrasonic atomization sheet.

[0024] Furthermore, a first welding point connected to the surface electrode is provided at the outer edge of the piezoelectric substrate, and a second welding point connected to the driving electrode is provided at the outer edge of the piezoelectric substrate; the first welding point and the second welding point are both provided in the fixed section.

[0025] The fixed section has a small atomization amplitude. The first and second welding points are arranged in the fixed section with a small amplitude to prevent the first and second welding points from being pulled off when the ultrasonic atomizer is atomized, thereby ensuring the reliability of electrical conduction and the reliability of the ultrasonic atomizer. At the same time, the first and second welding points are arranged in the fixed section to avoid high temperatures during the welding process that affect the performance of the atomizer section and extend the service life of the ultrasonic atomizer.

[0026] Compared with the prior art, the invention has good atomization effect, large smoke volume, small size and long service life. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0065] like Figures 1 to 6 As shown, the ultrasonic electronic cigarette includes a shell 2, in which a fixing seat 20, an ultrasonic atomizing sheet 1, an oil guiding mechanism 3 and an oil tank 4 are arranged. The ultrasonic atomizing sheet 1 is fixed by the fixing seat 20, and the oil tank 4 is connected with the atomizing surface of the ultrasonic atomizing sheet 1 through the oil guiding mechanism 3; the ultrasonic atomizing sheet 1 includes a sheet-like piezoelectric substrate 101, a surface electrode 102 fixedly arranged on the surface of one side of the piezoelectric substrate 101, and a driving electrode 103 fixedly arranged on the surface of the other side of the piezoelectric substrate 101, and the piezoelectric substrate 101 is in a long strip shape; the piezoelectric substrate 101 is composed of an interconnected atomizing section 106 and a fixed section 107, and the fixed section 107 is fixed by the fixing seat 20, the surface of the atomizing section 106 is in contact with the tobacco oil, and the tobacco oil is atomized to produce smoke through high-frequency oscillation, and the atomizing section 106 is suspended in the atomizing chamber of the ultrasonic electronic cigarette. The oil guide mechanism 3 conducts the smoke oil in the oil tank 4 to the atomization section 106 for atomization; the material of the oil guide mechanism 3 is lipophilic oil guide cotton, the fixing seat 20 is made of a material with a certain elasticity, such as silicone, and the material of the piezoelectric substrate 101 is piezoelectric ceramics.

[0066] Since the piezoelectric substrate 101 is in the shape of an elongated strip, the ultrasonic atomization sheet 1 made of the elongated piezoelectric substrate is also in the shape of an elongated strip, thereby reducing the size of the ultrasonic electronic cigarette using the ultrasonic atomization sheet 1 and making it more convenient for users to carry.

[0067] In this implementation case, the ultrasonic atomizer sheet 1 of the ultrasonic electronic cigarette is clamped on the fixed section 107 of the ultrasonic atomizer sheet 1 through the fixed seat 20; the atomizer section 106 of the ultrasonic atomizer sheet 1 is in contact with the oil-conducting cotton; during the atomization process, since the fixed section 107 is clamped and fixed by the fixed seat 20, the amplitude of the fixed section 107 is relatively weak, and the atomizer section 106 of the ultrasonic atomizer sheet 1 is suspended in the air without any restraint, so the amplitude is relatively large, the atomization effect is good, and the amount of smoke is large.

[0068] A limiting plate 5 is provided in the housing 2, and an atomizing chamber (not marked) is formed between the limiting plate 5 and the oil chamber 4; the atomizing section 106 of the ultrasonic atomizing sheet 1 is inserted into the atomizing chamber, and the fixing section 107 of the ultrasonic atomizing sheet 1 is arranged outside the atomizing chamber and is clamped and fixed by the fixing seat 20; one end of the oil guiding mechanism 3 is inserted into the oil chamber 4, and the other end of the oil guiding mechanism 3 extends into the atomizing chamber and contacts with the atomizing section 106 of the ultrasonic atomizing sheet 1; the oil guiding mechanism 3 in this implementation case is perpendicular to the atomizing section 106 of the ultrasonic atomizing sheet 1, and there is a gap 6 between the limiting plate 5 and the atomizing section 106 of the ultrasonic atomizing sheet 1, so as to increase the amplitude of the atomizing section 106 during the high-frequency oscillation of the ultrasonic atomizing sheet 1 and improve the atomization effect.

[0069] Since there is a gap 6 between the limiting plate 5 and the atomizing section 106 of the ultrasonic atomizing sheet 1, the heat generated by the ultrasonic atomizing sheet 1 during operation is slowly dissipated to the limiting plate 5, so the heat can be further absorbed by the smoke to improve the taste of the smoke. At the same time, since the ultrasonic atomizing sheet 1 is in a long strip shape, the high temperature generated by the atomizing section 106 during operation can be conducted to the fixed section 107, thereby preventing the atomizing section 106 from breaking due to high temperature during operation and extending the service life of the ultrasonic atomizing sheet 1.

[0070] An atomizing outer sleeve 7 and an atomizing inner sleeve 8 are provided in the shell 2. The oil guiding mechanism 3 is a long cup-shaped structure, which has the same shape as the ultrasonic atomizing sheet 1, and can increase the contact area between the oil guiding mechanism 3 and the ultrasonic atomizing sheet 1. The side wall of the oil guiding mechanism 3 is sleeved between the atomizing outer sleeve 7 and the atomizing inner sleeve 8, and the outer bottom surface of the oil guiding mechanism 3 is in contact with the atomizing surface of the ultrasonic atomizing sheet 1.

[0071] A partition plate 9 is provided inside the atomizer inner sleeve 8, and the partition plate 9 divides the atomizer inner sleeve 8 into a first cavity 10 and a second cavity 11. The first cavity 10 is communicated with the oil tank 4, and the second cavity 11 is communicated with the inner bottom surface of the oil guide mechanism 3; an oil passage groove 801 communicating with the oil tank 4 and the oil guide mechanism 3 is provided on the side wall of the atomizer inner sleeve 8 corresponding to the first cavity 10, and the smoke oil in the oil tank 4 contacts the oil guide mechanism 3 through the oil passage groove 801.

[0072] A suction nozzle 12 is connected to the top of the shell 2, and a ventilation pipe 13 is provided in the shell 2. One end of the ventilation pipe 13 is connected to the air inlet 14, and the other end of the ventilation pipe 13 passes through the first cavity 10 and is connected to the second cavity 11. The side wall of the oil guide mechanism 3 is provided with an air hole 301 connecting the second cavity 11 and the suction nozzle 12.

[0073] The second cavity 11 is a cavity connected to the atomizing surface of the ultrasonic atomizer sheet 1. The smoke generated by ultrasonic atomization is stored in the second cavity 11. The air enters the second cavity 11 from the air inlet 14 through the ventilation pipe, takes away the smoke in the second cavity 11 from the air hole 301, and enters the user's mouth through the nozzle 12.

[0074] The length direction of the ultrasonic atomizer sheet 1 is parallel to the length direction of the electronic cigarette, which is conducive to the miniaturization of the ultrasonic electronic cigarette.

[0075] A spring 15 is provided in the housing 2, one end of the spring 15 abuts against the outer wall of the atomizing inner sleeve 8, and the other end of the spring 15 abuts against the inner bottom surface of the oil guide mechanism 3. The spring 15 is used to achieve reliable contact between the oil guide mechanism 3 and the ultrasonic atomizing sheet.

[0076] The housing 2 is also provided with a bracket 16, a PCB board 17 and a battery 18, and the PCB board 17, the battery 18, the fixing seat 20 and the atomizing jacket 7 are all fixed by the bracket 16. The limiting plate 5 fixes the fixing seat 20 on the bracket 16, thereby fixing the ultrasonic atomizing sheet 1 to prevent the ultrasonic atomizing sheet 1 from tilting during operation and affecting the atomizing effect; a smoke oil cover 21 is provided at the opening of the oil tank 4, and the smoke oil cover 21 is opened to fill the oil tank 4 with oil.

[0077] The side wall of the housing 2 is provided with a button 19 for controlling whether the ultrasonic electronic cigarette works.

[0078] like Figures 7 to 10 The structure of the second embodiment of the ultrasonic atomizer sheet is shown in the figure. In the second embodiment, the ultrasonic atomizer sheet 1 includes a sheet-like piezoelectric substrate 101, a surface electrode 102 fixed on the surface of one side of the piezoelectric substrate 101, and a driving electrode 103 fixed on the surface of the other side of the piezoelectric substrate 101. The piezoelectric substrate 101 is in the shape of a long strip.

[0079] One side surface of the piezoelectric substrate 101 is fully covered by the surface electrode 102, and the central area of ​​the other side surface of the piezoelectric substrate 101 is covered by the driving electrode 103. The ratio of the surface electrode 102 area to the driving electrode 103 area is 3:2 to 4:1, and the preferred solution of this embodiment is 2:1. The atomization area is large, the amount of smoke is large, and the atomization effect is good.

[0080] The outer edge of the piezoelectric substrate 101 is provided with a first welding point 104 connected to the surface electrode 102, and the outer edge of the piezoelectric substrate 101 is provided with a second welding point 105 connected to the driving electrode 103. The two poles of the power supply are connected to the first welding point 104 and the second welding point 105 respectively, so that the two poles of the power supply can be electrically connected to the surface electrode 102 and the driving electrode 103.

[0081] The piezoelectric substrate 101 is made of piezoelectric ceramics.

[0082] The first welding point 104 and the second welding point 105 are both arranged in the fixed section 107 of the ultrasonic atomizer sheet 1. The ultrasonic atomizer sheet 1 is composed of two sections, the fixed section 107 and the atomizer section 106. Therefore, in the ultrasonic electronic cigarette using the ultrasonic atomizer sheet 1, the fixed section 107 is fixed by the fixing seat 20, so the atomization amplitude of the fixed section 107 is relatively small. The first welding point 104 and the second welding point 105 are arranged in the fixed section 107 with a relatively small amplitude to prevent the first welding point 104 and the second welding point 105 from being pulled off when the ultrasonic atomizer sheet 1 is atomized, thereby ensuring the reliability of the conductive and the working reliability of the ultrasonic atomizer sheet 1. At the same time, the first welding point 104 and the second welding point 105 are arranged in the fixed section, which can also avoid the generation of high temperature during the welding process and affect the performance of the atomizer section 106; the atomizer section 106 of the ultrasonic atomizer sheet 1 is suspended to increase the atomization amount.

[0083] like Figures 11 to 14 The structure of the third embodiment of the ultrasonic atomizer sheet is shown in the figure. In the third embodiment, the ultrasonic atomizer sheet 1 includes a sheet-like piezoelectric substrate 101, a surface electrode 102 fixed on the surface of one side of the piezoelectric substrate 101, and a driving electrode 103 fixed on the surface of the other side of the piezoelectric substrate 101. The piezoelectric substrate 101 is in the shape of a long strip. The piezoelectric substrate 101 is composed of an interconnected atomizing section 106 and a fixed section 107. The surface electrode 102 is fixed on the surface of one side of the atomizing section 106, and the driving electrode 103 is fixed on the surface of the other side of the atomizing section 106.

[0084] The piezoelectric substrate 101 is made of piezoelectric ceramics.

[0085] When the surface electrode 102 and the driving electrode 103 are energized, the atomizing section 106 performs high-frequency atomization driven by the potential change, and the atomization amplitude of the atomizing section 106 is the largest, so that the tobacco oil or other smoke-producing substances contacting the surface of the atomizing section 106 are atomized to generate smoke.

[0086] The surface electrode 102 and the driving electrode 103 are both rectangular, which can improve the atomization effect of the ultrasonic atomizer.

[0087] One side surface of the atomizing section 106 is fully covered by the surface electrode 102, and the central area of ​​the other side surface of the atomizing section 106 is covered by the driving electrode 103. The ratio of the area of ​​the surface electrode 102 to the area of ​​the driving electrode 103 is 3:2 to 4:1, and the preferred solution of this embodiment is 2:1.

[0088] The piezoelectric substrate 101 is also provided with a first welding point 104 connected to the surface electrode 102 and a second welding point 105 connected to the driving electrode 103 .

[0089] By connecting the two electrodes of the power supply to the first welding point 104 and the second welding point 105 respectively, the electrical connection between the two electrodes of the power supply and the surface electrode 102 and the driving electrode 103 can be achieved.

[0090] The first welding point 104 and the second welding point 105 are both arranged on the outer surface of the fixed section 107, the piezoelectric substrate 101 is fixed with a first conductive lead 108 connecting the first welding point 104 and the surface electrode 102, and the piezoelectric substrate 101 is fixed with a second conductive lead 109 connecting the second welding point 105 and the driving electrode 103.

[0091] The first welding point 104 and the second welding point 105 are arranged in the fixed section 107 with a relatively small amplitude, so as to prevent the first welding point 104 and the second welding point 105 from being pulled off when the ultrasonic atomization sheet 1 is atomized, thereby ensuring the reliability of the conductive and working reliability of the ultrasonic atomization sheet 1. At the same time, the first welding point 104 and the second welding point 105 are arranged in the fixed section 107, so as to avoid the generation of high temperature during the welding process and affect the performance of the atomization section 106.

[0092] like Figure 15 to Figure 16 The structure of the fourth embodiment of the ultrasonic atomizer is shown in the figure. The fourth embodiment repeats the third embodiment, except that the fourth embodiment does not include the first conductive lead 108 and the second conductive lead 109, the first solder joint 104 is arranged at the outer edge of the surface electrode 102, and the second solder joint 105 is arranged at the outer edge of the driving electrode 103. The first solder joint 104 is directly arranged next to the surface electrode 102, and the second solder joint 105 is directly arranged next to the driving electrode 103, avoiding the use of conductive leads to connect the solder joints and electrodes, thereby reducing costs.

[0093] like Figures 17 to 19The structure of the fifth embodiment of the ultrasonic atomizer is shown in the figure. The fifth embodiment repeats the third embodiment, except that the first conductive lead 108 is in the shape of an isosceles trapezoid, the large end of the first conductive lead 108 is smoothly connected to the surface electrode 102, and the small end of the first conductive lead 108 is smoothly connected to the first welding point 104; the second conductive lead 109 is in the shape of an isosceles trapezoid, the large end of the second conductive lead 109 is smoothly connected to the driving electrode 103, and the small end of the second conductive lead 109 is smoothly connected to the second welding point 105. There are no large sharp corners at the transition connection between the first conductive lead 108 and the surface electrode 102 and the transition connection between the second conductive lead 109 and the driving electrode 103, which is convenient for processing and more stable for bonding.

[0094] In addition, in the fifth embodiment, one side surface of the atomizing section 106 is composed of a covering area I with a surface electrode 102 fixed thereon and an exposed area II without a surface electrode 102 fixed thereon. The covering area I and the exposed area II are arranged along the length direction of the atomizing section 106, and the covering area I is closer to the fixed section 107 than the exposed area II; the ratio of the area of ​​the surface electrode 102 to the area of ​​the driving electrode 103 is 2:1. The surface electrode 102 is at a distance from the end of the atomizing section 106, so that the heat generated by the ultrasonic atomizing sheet 1 during the atomization process can be diffused to both ends, so that the heat dissipation speed is fast, the atomization effect is better, and the atomizing section 106 is prevented from being broken due to high temperature during operation, thereby extending the service life of the ultrasonic atomizing sheet 1.

[0095] like Figure 20 to Figure 22 The structure of the sixth embodiment of the ultrasonic atomizer is shown in the figure. The sixth embodiment repeats the fourth embodiment, except that one side surface of the atomizer section 106 is composed of a covering area I with a surface electrode 102 fixed thereon and an exposed area II without a surface electrode 102 fixed thereon. The covering area I and the exposed area II are arranged along the length direction of the atomizer section 106, and the covering area I is closer to the fixed section 107 than the exposed area II. The ratio of the area of ​​the surface electrode 102 to the area of ​​the driving electrode 103 is 3:2 to 4:1, and the preferred solution of this embodiment is 2:1. The surface electrode 102 is at a distance from the end of the atomizer section 106, so that the heat generated by the ultrasonic atomizer 1 during the atomization process can be diffused to both ends, so that the heat dissipation speed is fast, the atomization effect is better, and the atomizer section 106 is prevented from being broken due to high temperature during operation, thereby extending the service life of the ultrasonic atomizer 1.

[0096] like Figure 23 to Figure 26The structure of the seventh embodiment of the ultrasonic atomizer sheet is shown in the figure. In the seventh embodiment, the ultrasonic atomizer sheet 1 includes a sheet-shaped piezoelectric substrate 101, a surface electrode 102 fixedly arranged on one side of the piezoelectric substrate 101, and a driving electrode 103 fixedly arranged on the other side of the piezoelectric substrate 101. The structural characteristics are that the piezoelectric substrate 101 is in the shape of a long strip, and the piezoelectric substrate 101 is composed of an interconnected atomizing section 106 and a fixed section 107. The surface electrode 102 is fixedly arranged on one side of the atomizing section 106, and the driving electrode 103 is fixedly arranged on the other side of the atomizing section 106. The surface electrode 102 and the driving electrode 103 are both circular.

[0097] The piezoelectric substrate 101 is made of piezoelectric ceramics.

[0098] When the surface electrode 102 and the driving electrode 103 are energized, the atomizing section 106 performs high-frequency atomization driven by the potential change, and the atomization amplitude of the atomizing section 106 is the largest, so that the tobacco oil or other smoke-producing substances contacting the surface of the atomizing section 106 are atomized to generate smoke.

[0099] The outer end of the atomizing section 106 is an arc surface. One side of the atomizing section 106 is fully covered by the surface electrode 102, and the central area of ​​the other side of the atomizing section 106 is covered by the driving electrode 103. The ratio of the surface electrode 102 area to the driving electrode 103 area is 2:1.

[0100] The piezoelectric substrate 101 is also provided with a first welding point 104 connected to the surface electrode 102 and a second welding point 105 connected to the driving electrode 103 .

[0101] By connecting the two electrodes of the power supply to the first welding point 104 and the second welding point 105 respectively, the electrical connection between the two electrodes of the power supply and the surface electrode 102 and the driving electrode 103 can be achieved.

[0102] The first welding point 104 and the second welding point 105 are both arranged on the outer surface of the fixed section 107, the piezoelectric substrate 101 is fixed with a first conductive lead 108 connecting the first welding point 104 and the surface electrode 102, and the piezoelectric substrate 101 is fixed with a second conductive lead 109 connecting the second welding point 105 and the driving electrode 103.

[0103] The first welding point 104 and the second welding point 105 are arranged in the fixed section 107 with a relatively small amplitude, so as to prevent the first welding point 104 and the second welding point 105 from being pulled off when the ultrasonic atomization sheet 1 is atomized, thereby ensuring the reliability of the conductive and working reliability of the ultrasonic atomization sheet 1. At the same time, the first welding point 104 and the second welding point 105 are arranged in the fixed section 107, so as to avoid the generation of high temperature during the welding process and affect the performance of the atomization section 106.

[0104] like Figure 27 to Figure 28The structure of the ultrasonic atomizer sheet in the eighth embodiment is shown in the figure. The eighth embodiment repeats the seventh embodiment, except that the eighth embodiment does not include the first conductive lead 108 and the second conductive lead 109, the first solder joint 104 is arranged at the outer edge of the surface electrode 102, and the second solder joint 105 is arranged at the outer edge of the driving electrode 103. The first solder joint 104 is directly arranged next to the surface electrode 102, and the second solder joint 105 is directly arranged next to the driving electrode 103, avoiding the use of conductive leads to connect the solder joints and electrodes, thereby reducing costs.

[0105] like Figure 29 to Figure 31 The structure of the ninth embodiment of the ultrasonic atomizer sheet is shown in the figure. The ninth embodiment repeats the seventh embodiment, except that the first conductive lead 108 is in the shape of an isosceles trapezoid, the large end of the first conductive lead 108 is smoothly connected to the surface electrode 102, and the small end of the first conductive lead 108 is smoothly connected to the first welding point 104; the second conductive lead 109 is in the shape of an isosceles trapezoid, the large end of the second conductive lead 109 is smoothly connected to the driving electrode 103, and the small end of the second conductive lead 109 is smoothly connected to the second welding point 105. There are no large sharp corners at the transition connection between the first conductive lead 108 and the surface electrode 102 and the transition connection between the second conductive lead 109 and the driving electrode 103, which is convenient for processing and more stable for bonding.

[0106] In addition, in the ninth embodiment, one side surface of the atomizing section 106 is composed of a covering area I with a surface electrode 102 fixed thereon and an exposed area II without a surface electrode 102 fixed thereon. The covering area I and the exposed area II are arranged along the length direction of the atomizing section 106, and the covering area I is closer to the fixed section 107 than the exposed area II; the ratio of the area of ​​the surface electrode 102 to the area of ​​the driving electrode 103 is 2:1. The surface electrode 102 is at a distance from the end of the atomizing section 106, so that the heat generated by the ultrasonic atomizing sheet 1 during the atomization process can be diffused to both ends, so that the heat dissipation speed is fast, the atomization effect is better, and the atomizing section 106 is prevented from being broken due to high temperature during operation, thereby extending the service life of the ultrasonic atomizing sheet 1.

[0107] like Figure 32 to Figure 34 The structure of the ultrasonic atomizer sheet embodiment 10 is shown in the figure. The embodiment 10 repeats the embodiment 8, but the difference is that one side surface of the atomizer section 106 is composed of a covering area I with a surface electrode 102 fixed thereon and an exposed area II without a surface electrode 102 fixed thereon. The covering area I and the exposed area II are arranged along the length direction of the atomizer section 106, and the covering area I is closer to the fixed section 107 than the exposed area II; the ratio of the area of ​​the surface electrode 102 to the area of ​​the driving electrode 103 is 2:1. The surface electrode 102 is at a distance from the end of the atomizer section 106, so that the heat generated by the ultrasonic atomizer sheet 1 during the atomization process can be diffused to both ends, so that the heat dissipation speed is fast, the atomization effect is better, and the atomizer section 106 is prevented from being broken due to high temperature during operation, thereby extending the service life of the ultrasonic atomizer sheet 1.

[0108] like Figure 35 to Figure 37 The structure of the ultrasonic atomizer embodiment 11 is shown in the figure. The embodiment 11 repeats the embodiment 7, except that the outer ends of the atomizing section 106 and the fixing section 107 are both arc surfaces. There is no need to distinguish the atomizing section 106 and the fixing section 107 during processing, which saves production time and cost.

The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the enlightenment of the present invention, ordinary technicians in this field can also make many forms without departing from the scope of protection of the present invention and the claims, which all belong to the protection scope of the present invention.
