Description

Technical Field

[0001] The invention relates to an electronic smoking device, in particular to an electronic cigarette atomization core and an atomizer. Background Art

[0002] The upper surface electrode of the ultrasonic atomizer of the existing ultrasonic electronic cigarette atomizer is generally connected to the electrode assembly through a wire, so the atomizer core is inconvenient to assemble, and the solder joints at both ends of the wire are easy to fall off, resulting in poor conductivity of the ultrasonic atomizer. In addition, during the ultrasonic atomization process, due to the slow supply speed of the smoke oil, the ultrasonic atomizer is prone to dry burning, and because the air pipe is directly connected to the atomization chamber, during the atomization process, the smoke oil splashed on the ultrasonic atomizer enters the ventilation pipe connected to the suction nozzle, so it is easy to inhale the smoke oil. Summary of the invention

[0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide an electronic cigarette atomizer core and an atomizer which are easy to assemble, do not require welding wires, and can protect the ultrasonic atomizer sheet.

[0004] In order to solve the above technical problems, the present invention provides an electronic cigarette atomization core, which includes an atomization outer sleeve and an atomization inner sleeve, the atomization inner sleeve is sleeved on the upper part of the inner cavity of the atomization outer sleeve, a cotton compression spring is arranged between the bottom of the atomization inner sleeve and the oil-conducting cotton, an ultrasonic atomization sheet, an elastic insulating seat and an electrode assembly are arranged in sequence from top to bottom in the lower part of the inner cavity of the atomization outer sleeve, and an atomization cavity is arranged between the bottom of the atomization inner sleeve and the ultrasonic atomization sheet, the ultrasonic atomization sheet includes an upper surface electrode, a piezoelectric ceramic and a lower surface electrode arranged in sequence from top to bottom, the electrode assembly includes an elastic electrode, an insulating ring and a conductive bottom ring sleeved on each other from inside to outside, a top ring for supporting the upper surface electrode is arranged on the lower part of the inner wall of the atomization outer sleeve, and a yield portion is arranged on the outer periphery of the top ring for preventing the side wall of the ultrasonic atomization sheet from being squeezed and broken, the bottom of the inner wall of the atomization outer sleeve is directly electrically connected to the conductive bottom ring of the electrode assembly, and the lower surface electrode of the ultrasonic atomization sheet is electrically connected to the elastic electrode of the electrode assembly.

[0005] In this way, the top ring of the atomizing sleeve is directly supported on the upper surface electrode of the ultrasonic atomizing sheet, and then the bottom of the inner wall of the atomizing sleeve is directly connected to the electrode assembly. Electrical connection can be achieved without welding wires. Moreover, the setting of the yielding part ensures that the assembled ultrasonic atomizing sheet is only subjected to the supporting force of the top ring, which can protect the ultrasonic atomizing sheet.

[0006] Furthermore, the lower surface of the ultrasonic atomization sheet is arranged on the upper surface of the elastic insulating seat, so as to prevent the ultrasonic atomization sheet from being squeezed and broken or losing the atomization function through the elasticity of the elastic insulating seat itself.

[0007] Further, an installation part is arranged at the upper part of the inner cavity of the elastic insulating seat, and the ultrasonic atomization sheet is installed on the installation part to prevent the side wall of the ultrasonic atomization sheet from being scratched or extruded due to the shaking of the ultrasonic atomization sheet after assembly.

[0008] Further, a first oil passing port is arranged on the side wall of the atomization outer sleeve, an oil guiding cotton is clamped between the atomization outer sleeve and the atomization inner sleeve, one end of the oil guiding cotton covers the first oil passing port, and an air supplementing groove for delivering gas to the oil storage chamber is arranged on the outer wall of the atomization inner sleeve corresponding to the first oil passing port, and the air supplementing groove is communicated with the first air inlet channel.

[0009] In the suction process, the oil storage chamber continuously supplies e-liquid, and at the same time, the intake air flow continuously supplements the oil storage chamber, increasing the air pressure in the oil storage chamber, thereby improving the e-liquid supply speed and effectively preventing the ultrasonic atomization sheet from dry burning.

[0010] Further, a boss for sealing and clamping the ventilation pipe is arranged in the middle of the inner cavity of the atomization inner sleeve, and an air outlet cavity is arranged below the boss, so that the e-liquid splashed during ultrasonic atomization condenses in the air outlet cavity, and it is not easy for users to inhale the e-liquid.

[0011] Further, two ventilation ports are symmetrically arranged at the top of the atomization inner sleeve, and ventilation grooves leading directly to the bottom of the atomization inner sleeve are respectively arranged on the outer wall of the atomization inner sleeve below the two ventilation ports. After the atomization outer sleeve and the atomization inner sleeve are sleeved with each other, the inner wall of the atomization outer sleeve and the ventilation grooves form two first air inlet channels. In this way, since the two first air inlet channels are symmetrically arranged and the split flow rates of the intake air flow passing through the two first air inlet channels are the same, the smoke in the atomization cavity can be taken away more fully.

[0012] Further, oil guiding cotton installation grooves for installing both ends of the oil guiding cotton are symmetrically arranged on the outer wall of the atomization inner sleeve. A clamping section for clamping the oil guiding cotton is arranged at the upper part of the oil guiding cotton installation groove, and a relaxation section is arranged at the lower part. The air supplementing groove is arranged in the relaxation section, and the depth of the oil guiding cotton installation groove in the clamping section is less than that in the relaxation section, so that the oil guiding cotton and the atomization inner sleeve form an integral body.

[0013] Further, the oil guiding cotton installation groove and the ventilation groove are arranged staggeredly.

[0014] Further, a supporting part is arranged at the upper part of the inner wall of the atomization outer sleeve, and a step is arranged at the top of the outer wall of the atomization inner sleeve, and the step is clamped and fixed on the supporting part, so as to realize the fixed connection between the atomization inner sleeve and the atomization outer sleeve.

An oil storage is arranged inside the oil storage device, and a second air inlet channel and a mouthpiece are arranged on the mouthpiece device. The above-mentioned electronic cigarette atomization core is arranged in the oil storage device, and a ventilation pipe is arranged between the mouthpiece and the convex platform of the atomization inner sleeve. A third air inlet channel is arranged between the outer wall of the ventilation pipe and the mouthpiece device and the oil storage device, and the second air inlet channel is communicated with the first air inlet channel through the third air inlet channel.

[0029] Embodiment 1:

[0030] like Figure 1 - Figure 4 As shown, the embodiment C of the electronic cigarette atomization core of the present invention comprises an atomization outer sleeve 1 made of conductive material, an elastic insulating sleeve 3 is sleeved on the outer periphery of the atomization outer sleeve 1, an atomization inner sleeve 2 is sleeved on the upper part of the inner cavity of the atomization outer sleeve 1, an oil-conducting cotton 4 is sandwiched between the atomization outer sleeve 1 and the atomization inner sleeve 2, a cotton-pressing spring 5 is arranged between the bottom of the atomization inner sleeve 2 and the oil-conducting cotton 4, an ultrasonic atomization sheet 6, an elastic insulating seat 7 and an electrode assembly 8 are arranged in sequence from top to bottom at the lower part of the inner cavity of the atomization outer sleeve 1, the ultrasonic atomization sheet 6 comprises an upper surface electrode, a piezoelectric ceramic and a lower surface electrode arranged in sequence from top to bottom, the electrode assembly 8 comprises an elastic electrode 81, an insulating ring 82 and a conductive bottom ring 83 mutually sleeved from inside to outside, the inner wall of the atomization outer sleeve 1 is directly electrically connected to the upper surface electrode of the ultrasonic atomization sheet 6 and the conductive bottom ring 83 of the electrode assembly 8, and the lower surface electrode of the ultrasonic atomization sheet 6 is electrically connected to the elastic electrode 81 of the electrode assembly 8. An atomization cavity 10 is arranged between the ultrasonic atomization sheet 6 and the bottom of the atomization inner sleeve 2. A first oil passage port 11 is provided on the side wall of the atomizing jacket 1, an insertion port 12 is provided on the top of the atomizing jacket 1, and a supporting portion 13 is provided on the upper portion of the inner wall of the atomizing jacket 1, and a top ring 14 is provided on the lower portion of the inner wall for resisting the upper surface electrode of the ultrasonic atomizing sheet 6, and a yield portion 15 is provided on the outer periphery of the top ring 14 for preventing the side wall of the ultrasonic atomizing sheet 6 from being squeezed and broken, so that after the atomizing core is assembled, the ultrasonic atomizing sheet 6 is only subjected to the resisting force of the top ring 14.

[0031] The top of the outer wall of the atomization inner sleeve 2 is provided with a step 21. Two ventilation openings 22 are symmetrically arranged on the step 21. Ventilation grooves 23 leading directly to the bottom of the atomization inner sleeve are respectively arranged on the outer walls of the atomization inner sleeve 2 below the two ventilation openings 22. After the atomization outer sleeve 1 and the atomization inner sleeve 2 are sleeved with each other, the inner wall of the atomization outer sleeve 1 and the ventilation grooves 23 form two first air intake channels. Oil guide cotton installation grooves 24 are also symmetrically arranged on the outer wall of the atomization inner sleeve 2. The oil guide cotton installation grooves 24 and the ventilation grooves 23 are staggered from each other. A clamping section 241 for clamping the oil guide cotton 4 is arranged in the upper part of the oil guide cotton installation groove 24, and a relaxation section 242 is arranged in the lower part. And the depth of the oil guide cotton installation groove in the clamping section 241 is less than the depth of the oil guide cotton installation groove in the relaxation section 242. An air supplement groove 243 communicating with the oil storage chamber is arranged in the relaxation section 242, and the bottom of the air supplement groove 243 communicates with the atomization chamber 10. The oil guide cotton 4 is sleeved in the oil guide cotton installation groove 24. The oil guide cotton 4 is clamped and fixed between the atomization inner sleeve 2 and the atomization outer sleeve 1 through the clamping section 241. The relaxation section 242 is aligned with the first oil passing opening 11 of the atomization outer sleeve 1, so that the oil guiding speed of the oil on the oil guide cotton 4 is more uniform and stable; the air supplement groove 243 quickly supplements air in the atomization chamber 10 to the oil storage chamber, realizing air-oil replacement in the sealed oil storage chamber, so that the oil outlet speed of the oil storage chamber is faster. A boss 25 is arranged in the middle of the inner cavity of the atomization inner sleeve 2. An air outlet cavity 26 is arranged below the boss 25. The ventilation pipe 9 of the atomizer is inserted into the air outlet cavity 26. When the ventilation pipe 9 is inserted into the boss 25 of the atomization inner sleeve 2 and the outer wall of the ventilation pipe 9 is clamped and sealed by the boss 25, the intake air flow can only enter the atomization chamber 10 through the two first air intake channels, then pass through the atomization surface of the ultrasonic atomization sheet 6 to take away the smoke, and then be discharged through the air outlet cavity 26 and the ventilation pipe 9. In this way, because the two first air intake channels are symmetrically arranged and the split flow of the intake air flow entering the two first air intake channels is the same, the smoke in the atomization chamber 10 is taken away more fully; because the air outlet cavity 26 is arranged, the atomized oil splashed by the ultrasonic atomization sheet 6 during ultrasonic atomization condenses in the air outlet cavity 26, making it difficult for users to inhale the atomized oil.

[0032] A second oil passing opening 31 is arranged on the side wall of the elastic insulating sleeve 3. The first and second oil passing openings 11 and 31 are aligned, and the first oil passing opening 11 is aligned with the oil outlet of the oil storage chamber. A convex column 32 is arranged on the inner wall of the elastic insulating sleeve 3. A clamping hole 16 is arranged on the side wall of the atomization outer sleeve 1. And the convex column 32 is clamped into the clamping hole 16, so that the elastic insulating sleeve 3 is fixed on the atomization outer sleeve 1, so that the atomization outer sleeve 1 can better seal the oil outlet during the rotation process.

[0033] When assembling the atomization core, first insert the U-shaped oil guide cotton 4 with the middle part placed with the pressing cotton spring 5 upward from below the atomization inner sleeve 2 into the oil guide cotton installation groove 24, so that both ends of the oil guide cotton 4 are respectively sleeved in the oil guide cotton installation grooves 24 on both sides of the atomization inner sleeve 2, thereby making the oil guide cotton 4 and the atomization inner sleeve 2 form an integral body; then insert the atomization inner sleeve 2 equipped with the oil guide cotton 4 into the atomization outer sleeve 1 through the insertion port 12 and clamp it with the inner wall of the atomization outer sleeve 1, making the fixation of the oil guide cotton 4 more stable, and making the step 21 snap-fitted and fixed on the support part 13 to realize the fixed connection between the atomization inner sleeve 2 and the atomization outer sleeve 1, with the relaxation section 242 aligned with the oil passing port 11, so that the oil guide cotton 4 can store and guide oil sufficiently; finally, place the ultrasonic atomization sheet 6, the elastic insulating seat 7 and the electrode assembly 8 in sequence at the bottom of the oil guide cotton 4, and make the top ring 14 on the inner wall of the atomization outer sleeve 1 abut against the upper surface electrode of the ultrasonic atomization sheet 6, and the bottom of the inner wall of the atomization outer sleeve 1 is threadedly connected with the conductive bottom ring 83 of the electrode assembly 8, and the lower surface electrode of the ultrasonic atomization sheet 6 is electrically connected with the elastic electrode 81 of the electrode assembly 8. The above assembly method is just one option. Obviously, it is also possible to first install the ultrasonic atomization sheet 6, the elastic insulating seat 7 and the electrode assembly 8 in the lower part of the inner cavity of the atomization outer sleeve 1, and then insert the atomization inner sleeve 2 equipped with the oil guide cotton 4 into the atomization outer sleeve 1 and clamp it with the inner wall of the atomization outer sleeve 1.

[0034] In the above embodiment, the elastic insulating seat 7 abuts against the lower surface of the ultrasonic atomization sheet 6, so the self-elasticity of the elastic insulating seat 7 can prevent the ultrasonic atomization sheet 6 from being squeezed and broken or losing the atomization function. However, as Figure 5 shown, an installation part 71 can also be provided in the elastic insulating seat 7 to install the ultrasonic atomization sheet 6 on the installation part 71 to prevent the side wall of the ultrasonic atomization sheet 6 from being scratched or squeezed due to the shaking of the ultrasonic atomization sheet 6 after assembly.

[0035] As Figure 6 、 Figure 7As shown in the figure, an embodiment of the electronic cigarette atomizer of the present invention includes an oil storage device A for accommodating the above-mentioned atomization core C. An oil storage A1 is provided in the oil storage device A. An oil outlet A11 is provided on the oil storage A1. The oil outlet A11 is connected to the first oil passage 11 on the atomization sleeve 1 through the second oil passage 31 on the elastic insulating sleeve 3, so that the e-liquid flows through the oil outlet A11, the second oil passage 31, and the first oil passage 11 to the wicking cotton 4, and then reaches the atomization surface of the ultrasonic atomization sheet 6 through the wicking cotton 4, and then forms smoke. An oil filling port A12 is provided at the top of the oil storage device A, and a mouthpiece device B is provided at the top of the oil storage device A. The mouthpiece device B is formed by the engagement of a mouthpiece cover B1 and an upper cover B2. Two second air intake channels B3 and two child lock structures B4 are provided between the mouthpiece cover B1 and the upper cover B2. A mouthpiece B11 is provided on the mouthpiece cover B1. The mouthpiece B11 is connected to the air outlet cavity 26 of the inner atomization sleeve 2 through an adapter B6 and an air pipe 9. The air pipe 9 is clamped and sealed by a boss 25 in the inner atomization sleeve 2. A third air intake channel B5 is provided between the outer wall of the air pipe 9 and the mouthpiece device B and the oil storage device A. The second air intake channel B3 communicates with the first air intake channel through the third air intake channel B5.

[0036] As Figures 8 - 11As shown in the figure, the two child lock structures B4 include a button B41 protruding from the outer shell of the nozzle device B, two limiting bosses B21 symmetrically arranged at the bottom of the upper cover B2, and a child lock mechanism installation groove B22, an arc-shaped limiting step movement groove A13 and a locking foot movement groove A14 arranged at the top of the oil tank device A relative to the two limiting steps B5. The central angles of the limiting step movement groove A13 and the locking foot movement groove A14 are 90 degrees. A clamping groove A141 is provided at the starting end of the locking foot movement groove A14, and limiting steps A131 are respectively provided at both ends of the limiting step movement groove A13. The depth of the locking foot movement groove A14 is greater than the depth of the limiting step movement groove A13. The button B41 includes a locking foot B411 provided at the bottom and a button spring B412 abutted against the nozzle cover B1. After the oil tank device A is combined with the nozzle device B, the two limiting bosses B21 are respectively clamped into the corresponding limiting step movement grooves A13, and the locking feet B411 of the two buttons B41 pass through the child lock mechanism installation groove B22 and are clamped into the clamping groove A141 of the locking foot movement groove A14. When the oil tank device A is aligned with the nozzle device B, the button B41 is blocked by the outer shell of the nozzle device B, and the two limiting bosses B21 are limited by the limiting step A131 at one end of the limiting step movement groove A13. Therefore, the nozzle device B cannot rotate relative to the upper cover A1. When the two buttons B41 are pressed simultaneously to release the restriction of the outer shell of the nozzle device B, the locking foot B411 is released from the restriction of the clamping groove A141. When the nozzle device B rotates counterclockwise by 90 degrees around the oil tank device A, the locking foot B411 rotates counterclockwise in the locking foot movement groove A14, and the limiting boss B21 rotates counterclockwise by 90 degrees in the limiting step movement groove A13 to open the oil injection port A12 for convenient injection of e-liquid. At this time, the nozzle device B rotates clockwise by 90 degrees around the oil tank device A, the locking foot B411 rotates clockwise in the locking foot movement groove A14 and finally is clamped into the clamping groove A141, and the button B41 is clamped into the outer shell of the nozzle device B. The limiting boss B21 rotates clockwise by 90 degrees in the limiting step movement groove A13 and is finally limited by the limiting step A131 to close the oil injection port A12, and the nozzle device B cannot rotate relative to the oil tank device A.
