Description

Technical Field

[0001] The present invention particularly relates to an atomizer core and an assembly method thereof, and an atomizer. Background Art

[0002] Existing ultrasonic electronic cigarette atomizers have the following disadvantages:

[0003] First, there are many parts and hardware components when assembling the atomizer core, and the assembly steps are cumbersome. In addition, the oil-conducting cotton is easily wrinkled and deformed. In the process of conducting the e-liquid, sometimes the amount of e-liquid accumulates and causes bubbles or leaks. Sometimes the wrinkles hinder the rapid conduction of the e-liquid, resulting in dry burning. Therefore, it not only affects the user's experience of the smoke, but also affects the life of the ultrasonic atomizer and increases the production cost of the atomizer core.

[0004] Second, when disassembling the atomizer core, you need to tighten the screws, which is troublesome to operate and the screws are easy to slip, thus reducing the service life.

[0005] Third, the oil guide speed is unstable, which may affect the atomization effect and inhale the e-liquid due to too fast oil guide, and cause dry burning and ectopicity due to too slow oil guide, resulting in poor smoke taste, low e-liquid utilization rate and short service life. Summary of the invention

[0006] The object of the present invention is to provide an atomizer core and an assembly method thereof, and an atomizer, in view of the above-mentioned deficiencies in the prior art. The atomizer core can be assembled quickly and conveniently, and the oil guide cotton is not easy to deform; the atomizer core can be easily disassembled and assembled; the oil guide rate is uniform and stable, and the atomization effect is good.

[0007] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0008] An atomizer core comprises oil-conducting cotton, an ultrasonic atomizing sheet and an atomizing seat, wherein the ultrasonic atomizing sheet is fixedly arranged in the atomizing seat, and its structural feature is that the central area of ​​the oil-conducting cotton protrudes toward the atomizing surface of the ultrasonic atomizing sheet and contacts with the ultrasonic atomizing sheet, and the edge of the oil-conducting cotton has a bent edge extending toward the ultrasonic atomizing sheet, and the bent edge is sleeved outside the side wall of the atomizing seat.

[0009] With the above structure, when assembling the atomizer core, by sleeve-arranging the bent edge outside the side wall of the atomizer seat, the protruding end of the central area of ​​the oil-conducting cotton (the place in contact with the ultrasonic atomizer sheet) can be prevented from wrinkling, and the oil-conducting cotton can be well supported and shaped, and the periphery of the oil-conducting cotton other than the protrusion is not easy to deform, so that the oil-conducting cotton conducts the oil at a uniform rate, avoiding the phenomenon of dry burning or oil bubbling during the ultrasonic atomization of the oil (oil bubbling means that the surface of the ultrasonic atomizer sheet is soaked with too much oil, which affects its atomization effect).

[0010] Furthermore, it also includes a base and an elastic electrode, the elastic electrode is insulated and connected to the base through an insulating seat; a cavity is provided on the base, the atomizer seat is clamped in the cavity, and the elastic electrode abuts against an electrode layer of the ultrasonic atomizer sheet to achieve stable and reliable electrical connection.

[0011] As a first preferred embodiment, it further comprises a pressure ring having a fixing ring, the lower section of the atomizer seat is clamped in the cavity, the bent edge is sleeved between the upper section of the atomizer seat and the upper section of the fixing ring; the lower section of the fixing ring is buckled and connected to the base.

[0012] As a second preferred embodiment, the bent edge and the atomizer seat are both clamped in the cavity.

[0013] As a third preferred embodiment, it further comprises a pressure ring having a fixing ring, the lower section of the atomizer seat is clamped in the cavity, the bent edge is sleeved between the upper section of the atomizer seat and the fixing ring; the fixing ring is buckled and connected to the atomizer seat.

[0014] Furthermore, a conical platform facing the ultrasonic atomizing sheet is provided in the central area of ​​the pressure ring, and the conical platform abuts against the central area of ​​the oil-conducting cotton, so that the oil-conducting cotton has a shape corresponding to the conical platform.

[0015] Since a conical platform facing the ultrasonic atomizer is provided in the central area of ​​the pressure ring, when the pressure ring squeezes the oil-conducting cotton, the shape of the central area of ​​the oil-conducting cotton corresponds to the conical platform, thereby achieving reliable contact between the oil-conducting cotton and the ultrasonic atomizer and preventing the oil-conducting cotton from wrinkling.

[0016] Furthermore, it also includes an electronic wire, one end of which is connected to another electrode layer of the ultrasonic atomizer sheet, and the other end of the electronic wire passes through the atomizer seat and contacts the inner wall of the base to achieve stable and reliable electrical connection.

[0017] Furthermore, a first groove is provided on the top surface of the atomizer seat. Since the oil-conducting cotton at the position corresponding to the first groove is not squeezed by the top surface of the atomizer seat, the oil-conducting cotton at this position is relatively fluffy. Therefore, during the smoking process, the gas can more easily enter the oil cavity from the fluffy part of the oil-conducting cotton to realize oil-gas replacement. Therefore, the oil-conducting speed of the oil-conducting cotton at this position is faster, the atomization effect is more stable, and dry burning is prevented.

[0018] Based on the same inventive concept, the present invention also provides an assembly method of an atomizer core, comprising the steps of A. fixing an ultrasonic atomizer sheet in an atomizer seat;

[0019] Its features also include:

[0020] Step B: Sleeve the bent edge of the oil-conducting cotton outside the side wall of the atomizer seat, and make the protruding central area of ​​the oil-conducting cotton contact with the ultrasonic atomizer sheet.

[0021] Furthermore, it also includes:

[0022] Step C. Fixing the elastic electrode on the base through the insulating seat;

[0023] Step D: Install the atomizer seat in the cavity.

[0024] Furthermore, the initial shape of the oil-conducting cotton is a sheet;

[0025] The step B comprises:

[0026] Step B1, placing the oil-conducting cotton sheet on the top surface of the silicone sleeve;

[0027] Step B2, placing a pressure ring with a fixing ring on the sheet-like oil-conducting cotton; wherein a conical platform facing the ultrasonic atomizing sheet is provided in the central area of ​​the pressure ring;

[0028] Step B3, move the pressure ring toward the ultrasonic atomizer until the pressure ring is sleeved outside the atomizer seat. At this time, the conical stage squeezes the central area of ​​the oil-conducting cotton and forms a protrusion in the central area of ​​the oil-conducting cotton that contacts the atomizing surface of the ultrasonic atomizer, and forms a bent edge at the edge of the oil-conducting cotton that is sleeved between the atomizer seat and the fixed ring.

[0029] Furthermore, in the initial structure of the pressure ring, the fixing ring and the conical platform are connected via a connecting portion;

[0030] The step B comprises:

[0031] Step B4, cutting off the connection portion and removing the conical platform from the pressure ring.

[0032] Use scissors or other tools to cut off the connection part. The whole assembly process is convenient, the oil-conducting cotton can be accurately shaped, the oil-conducting cotton can be ensured to conduct oil smoothly, and the assembly cost can be greatly saved.

[0033] Based on the same inventive concept, the present invention also provides an atomizer, including a shell, an oil tank is arranged in the shell, and the atomizer core is also included, the atomizer core is detachably connected to the shell, and the oil tank is connected to the oil guide cotton through the oil outlet hole.

[0034] By means of the above structure, the oil-conducting cotton abuts against the end of the oil outlet hole away from the oil bin, and the smoke oil can directly flow through the oil outlet hole to the oil-conducting cotton to provide smoke oil for the ultrasonic atomizer.

[0035] Furthermore, it also includes oil storage cotton, which is arranged in the oil outlet hole, and the bottom of the oil tank is connected with the top surface of the oil guide cotton through the oil storage cotton in the oil outlet hole.

[0036] By means of the above structure, if the oil outlet hole is set at the bottom of the oil bin, the oil storage cotton passes through the oil outlet hole and the top of the oil storage cotton is communicated with the oil bin, and the bottom of the oil storage cotton is in contact with the oil guide cotton, thereby conducting the smoke oil in the oil bin to the bottom of the central area of ​​the oil guide cotton and contacting the ultrasonic atomization piece; if the oil outlet hole is set on the side wall of the oil bin, the oil storage cotton passes through the oil outlet hole and one end of the oil storage cotton is communicated with the bottom of the oil bin, and the other end of the oil storage cotton is in contact with the oil guide cotton, thereby conducting the smoke oil in the oil bin to the bottom of the central area of ​​the oil guide cotton and contacting the ultrasonic atomization piece, thereby making the oil conduction rate more uniform and stable, and the atomization effect is good.

[0037] Furthermore, it also includes a rotary cover connected to the top of the outer shell and rotatable around the central axis of the outer shell, a rotary shaft is provided in the outer shell, one end of the rotary shaft is fixedly connected to the rotary cover, and a baffle portion is provided on the outer wall of the other end of the rotary shaft, and a second groove is provided on the baffle portion; an oil filling hole is opened on the top of the oil tank, and a sealing plug corresponding to the oil filling hole is provided on the rotary cover; when the rotary cover is rotated until the sealing plug closes the oil filling hole, the second groove is opposite to the oil outlet hole and the oil outlet hole is opened; when the rotary cover is rotated until the sealing plug is separated from the oil filling hole and the oil filling hole is opened, the baffle portion is opposite to the oil outlet hole, the second groove is staggered with the oil outlet hole, and the oil outlet hole is closed.

[0038] With the above structure, when smoking normally, the second groove is directly opposite to the oil outlet hole, and the smoke oil can be guided to the oil guide cotton through the oil outlet hole, and the oil guide cotton can smoothly guide the smoke oil to the ultrasonic atomizer for atomization. When oil filling is needed, rotate the rotary cover, and the rotary cover drives the rotary shaft to rotate synchronously. The oil filling hole begins to slowly expose, and at the same time, the baffle part slowly covers the oil outlet hole, that is, the oil guide area of ​​the oil storage cotton gradually decreases. Finally, the oil filling hole is fully opened and the oil outlet hole is completely closed, so as to avoid the oil tank leaking oil through the oil outlet hole to the ultrasonic atomizer when the oil filling hole is opened, causing the ultrasonic atomizer to bubble oil. The whole process is easy to operate.

DETAILED DESCRIPTION

[0058] like Figure 1 and Figure 2 As shown, in the first embodiment, the atomizer core 26 includes an oil-conducting cotton 1, an ultrasonic atomizer sheet 2 and an atomizer seat 3, wherein the ultrasonic atomizer sheet 2 is fixedly arranged in the atomizer seat 3, the central area of ​​the oil-conducting cotton 1 protrudes toward the atomization surface of the ultrasonic atomizer sheet 2 and contacts the ultrasonic atomizer sheet 2, the protruding position of the oil-conducting cotton 1 contacts the ultrasonic atomizer sheet 2, and the other positions of the oil-conducting cotton 1 do not contact the ultrasonic atomizer sheet 2, and the smoke oil is diverted to the protruding position through the other positions of the oil-conducting cotton 1, so that the smoke oil on the surface of the ultrasonic atomizer sheet 2 participates in ultrasonic atomization to generate smoke; the edge of the oil-conducting cotton 1 has a bending edge 101 extending in the direction of the ultrasonic atomizer sheet 2, and the bending edge 101 is sleeved outside the side wall of the atomizer seat 3. When assembling the atomizer core 26, by sleeved the bending edge 101 outside the side wall of the atomizer seat 3, the oil-conducting cotton 1 can be well supported and shaped, the oil-conducting cotton 1 is not easy to deform, and it is ensured that the protruding position of the oil-conducting cotton 1 contacts the ultrasonic atomizer sheet.

[0059] The atomizer core embodiment 1 further includes a base 4 and an elastic electrode 5, the elastic electrode 5 is insulated and connected to the base 4 through an insulating seat 6; a cavity 401 is provided on the base 4, the atomizer seat 3 is clamped in the cavity 401, and the elastic electrode 5 is in contact with an electrode layer of the ultrasonic atomizer sheet 2 to achieve a stable and reliable electrical connection. The insulating seat 6 is made of silicone or the like.

[0060] The atomizer core embodiment 1 also includes a pressure ring 7, which has a fixing ring 701. The lower section of the atomizer seat 3 is clamped in the cavity 401, and the bent edge 101 is sleeved between the upper section of the atomizer seat 3 and the upper section of the fixing ring 701; the inner wall of the lower section of the fixing ring 701 is provided with a buckle groove 7011, and the outer wall of the base 4 is provided with a groove 402. The lower section of the fixing ring 701 and the base 4 are buckled together by the buckle groove 7011 and the groove 402.

[0061] The top surface of the atomizer seat 3 is provided with a first groove 301, and the oil-conducting cotton 1 at the position corresponding to the first groove 301 is relatively fluffy, which is conducive to the conduction of the smoke oil. At the same time, when inhaling, the first groove 301 will communicate with the air inlet 1301 through the oil-conducting cotton 1. Due to the existence of airflow, there is a certain airflow negative pressure at the first groove 301, so some gas enters the oil tank 10 through the first groove 301 to achieve oil-gas exchange, so the smoke oil in the oil tank 10 is more evenly guided by the oil-conducting cotton 1, so that the atomization effect is more stable, it is not easy to inhale oil or dry burning, the smoke volume is stable, and the smoke taste is good.

[0062] The atomizer core 26 also includes an electronic wire 8, one end of which is connected to the other electrode layer of the ultrasonic atomizer sheet 2, and the other end of the electronic wire 8 passes through the atomizer seat 3 and contacts the inner wall of the base 4 to achieve a stable and reliable electrical connection.

[0063] like Figure 3 and Figure 4 As shown, the atomizer core embodiment 2 repeats the embodiment 1, except that the atomizer core 26 in the embodiment 2 does not include the pressure ring 7, but includes the first sealing ring 17, the bent edge 101 and the atomizer seat 3 are both clamped in the cavity 401, and the bent edge 101 is clamped between the inner wall of the cavity 401 and the outer wall of the upper section of the atomizer seat 3. The bent edge 101 is clamped by the matching tightness of the inner wall of the cavity 401 and the outer wall of the upper section of the atomizer seat 3, so that the oil-conducting cotton 1 is not easily deformed, and the first sealing ring 17 is sleeved on the outside of the base 4 to improve the sealing when the atomizer core 26 is assembled.

[0064] like Figure 5 As shown, the atomizer core embodiment 3 repeats the embodiment 1, except that in the atomizer core embodiment 3, the central area of ​​the pressure ring 7 is provided with a conical platform 702 facing the ultrasonic atomizer sheet 2, and the conical platform 702 abuts against the central area of ​​the oil guide cotton 1. The lower section of the atomizer seat 3 is clamped in the cavity 401, and the bent edge 101 is sleeved between the upper section of the atomizer seat 3 and the fixing ring 701; the fixing ring 701 is connected to the atomizer seat 3 by buckles.

[0065] Since the central area of ​​the pressure ring 7 is provided with a conical platform 702 facing the ultrasonic atomizer 2, when the pressure ring 7 squeezes the oil-conducting cotton 1, the shape of the central area of ​​the oil-conducting cotton 1 corresponds to the conical platform 702, which can prevent the oil-conducting cotton 1 from wrinkling and achieve reliable contact between the oil-conducting cotton 1 and the ultrasonic atomizer 2.

[0066] like Figure 6 As shown, in the first embodiment, the initial shape of the oil-conducting cotton 1 is a sheet. In the initial structure of the pressing ring 7, the central area of ​​the pressing ring 7 is provided with a conical platform 702 facing the ultrasonic atomizing sheet 2; the fixing ring 701 and the conical platform 702 are connected by a connecting portion 703. The assembly method of the atomizing core 26 in the first embodiment includes:

[0067] Step A: Fix the ultrasonic atomization sheet 2 on the atomization seat 3.

[0068] Step B1, placing the sheet-shaped oil-conducting cotton 1 flatly on the top surface of the atomizer seat 3.

[0069] Step B2, placing the pressure ring 7 with the fixing ring 701 on the sheet-like oil-conducting cotton 1.

[0070] Step B3, move the pressure ring 7 carrying the oil-conducting cotton 1 toward the ultrasonic atomizer 2 until the pressure ring 7 is sleeved outside the atomizer seat 3. At this time, the conical platform 702 squeezes the central area of ​​the oil-conducting cotton 1 and forms a protrusion in the central area of ​​the oil-conducting cotton 1 that contacts the atomizer cotton of the ultrasonic atomizer 2, and forms a bent edge 101 at the edge of the oil-conducting cotton 1 that is sleeved between the atomizer seat 3 and the fixed ring 701.

[0071] Step C: Fix the elastic electrode 5 on the base 4 through the insulating seat 6 .

[0072] Step D: clamp the atomizer seat 3 in the cavity 401 .

[0073] Step B4, cutting off the connection part 703, and removing the conical platform 702 from the pressing ring 7. Cutting off the connection part 703 with a tool such as scissors, the whole process is convenient for assembly, and the oil-conducting cotton 1 can be accurately shaped to ensure smooth oil conduction of the oil-conducting cotton 1, and greatly save assembly costs.

[0074] In the second embodiment, since the pressure ring 7 is not provided, the shape of the oil-conducting cotton 1 needs to be pre-formed. During assembly, the bent edge 101 of the oil-conducting cotton 1 is directly sleeved outside the side wall of the atomizing seat 3, and the protruding central area of ​​the oil-conducting cotton 1 is in contact with the ultrasonic atomizing sheet 2. Finally, the first sealing ring 17 needs to be sleeved outside the base 4. The remaining steps are similar to those in the first embodiment, and are not described in detail here, but do not affect the understanding and implementation of the present invention by those skilled in the art.

By utilizing the elastic deformation ability of the first locking hook 901, the atomizer core 26 can be easily and quickly plugged in and out, and it is very convenient to replace the atomizer core 26. Since the atomizer core 26 is a wearing part in the entire atomizer, it can save costs to quickly and separately replace the atomizer core 26. The oil tank 10 is connected to the oil guide cotton 1 through the oil outlet 11.

[0077] The atomizer also includes an oil storage cotton 12, which is arranged in the oil outlet hole 11.

[0080] An oil filling hole 15 is provided on the top of the oil tank 10, and the oil filling hole 15 is provided on the top cover 19. A mounting hole 1302 is provided on the rotary cover 13, and a sealing plug 16 corresponding to the oil filling hole 15 is provided in the mounting hole 1302; when the rotary cover 13 is rotated until the sealing plug 16 closes the oil filling hole 15, the second groove 1402 is opposite to the oil outlet hole 11, and the oil outlet hole 11 is opened; when the rotary cover 13 is rotated until the sealing plug 16 is separated from the oil filling hole 15, and the oil filling hole 15 is opened, the baffle portion 1401 is opposite to the oil outlet hole 11, and the oil outlet hole 11 is closed.

[0081] The sealing plug 16 and the sealing seat 18 are made of silicone or the like, and the sealing plug 16 is embedded in the mounting hole 1302 of the rotary cover 13. The rotary cover 13 is provided with a semicircular limiting groove 1303, and the rotary shaft 14 is provided with a semicircular limiting convex portion 1403 corresponding to the limiting groove 1303. The rotary shaft 14 and the rotary cover 13 are riveted and the limiting convex portion 1403 is arranged in the limiting groove 1303, so as to realize the fixed connection between the rotary cover 13 and one end of the rotary shaft 14. The limiting groove 1303 cooperates with the limiting convex portion 1403 to limit the axial rotation between the rotary cover 13 and the rotary shaft 14, ensuring that when the rotary cover 13 rotates, the rotary shaft 14 can be driven to rotate synchronously, and the oil outlet 11 can be reliably closed when oil is filled.

[0082] An insulating tube 22 is also provided in the sealing seat 18 , one end of a cotton pressing spring 23 is fixed in the insulating tube 22 , and the other end of the cotton pressing spring 23 abuts against the central area of ​​the oil-conducting cotton 1 , ensuring reliable contact between the central area of ​​the oil-conducting cotton 1 and the ultrasonic atomizing sheet 2 .

[0084] like Fig.11 and 12 As shown, the sealing seat 18, the oil storage cotton 12, the sealing strip 20, the housing 9, the heat insulation tube 22, and the cotton pressing spring 23 together form a bin assembly 24. Fig.13 and Fig.14 As shown, the rotary cover 13, the sealing plug 16, the top cover 19, and the rotating shaft 14 together form a rotating assembly 25. During assembly, the housing assembly 24 and the atomizer core 26 are connected by snapping together through the first locking hook 901 and the first locking groove 403, and the rotating assembly 25 and the housing assembly 24 are connected by snapping together through the second locking hook 1901 and the second locking groove 902, so that assembly and disassembly are very convenient and quick.
