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] In the ultrasonic atomization process of the existing ultrasonic electronic cigarette atomizer, the ultrasonic atomization sheet is prone to dry burning due to the slow supply speed of the smoke oil. In addition, since the air pipe is directly connected to the atomization chamber, the smoke oil splashed on the ultrasonic atomization sheet enters the ventilation pipe connected to the suction nozzle during the atomization process, making it 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 have fast smoke oil supply and prevent dry burning of ultrasonic atomizer sheets.

[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 which are arranged mutually, a first oil passage port connected to an oil outlet of an oil tank is arranged on the side wall of the atomization outer sleeve, a U-shaped oil guide cotton is sandwiched between the atomization outer sleeve and the atomization inner sleeve, the end of the oil guide cotton covers the first oil passage port, an atomization cavity is arranged at the bottom of the atomization inner sleeve, a plurality of air inlet grooves are arranged on the side wall of the atomization inner sleeve, which penetrate the atomization inner sleeve along its axial direction and are consistent with the flow direction of the smoke oil flowing into the atomization cavity, and at least one air inlet groove is connected to the first oil passage port through the surface of the oil guide cotton away from the oil outlet of the oil tank.

[0005] At least one air inlet groove of the present invention is connected with the surface of the oil-conducting cotton, and the airflow direction in the air inlet groove is consistent with the flow direction of the smoke oil entering the atomizing chamber. Therefore, during the smoking process, there is gas flow in the air inlet groove, and the power of the gas flow overcomes the adhesion of the smoke oil on the oil-conducting cotton, so that the flow speed of the smoke oil in the oil-conducting cotton is accelerated; at the same time, the air pressure in the air inlet groove changes, so that the air pressure in the oil bin is unbalanced with the air pressure in the air inlet groove. Therefore, at the moment when the smoke oil is absorbed by the oil-conducting cotton at the first oil-passing port, the air passes through the first oil-passing port into the sealed oil bin to realize the replacement of air and smoke oil (just as bubbles appear in the oil bin when smoking), thereby accelerating the speed of the smoke oil being guided to the oil-conducting cotton, so that the smoke oil supply to the ultrasonic atomizing sheet for ultrasonic atomization is sufficient, thereby ensuring the amount of smoke during smoking and preventing the ultrasonic atomizing sheet from dry burning.

[0006] Furthermore, an oil-conducting cotton mounting groove for mounting the oil-conducting cotton is symmetrically arranged on the outer wall of the atomizer inner sleeve, a clamping section for clamping the oil-conducting cotton is arranged at the upper part of the oil-conducting cotton mounting groove, and a loosening section is arranged at the lower part, and the depth of the oil-conducting cotton mounting groove of the clamping section is less than the depth of the oil-conducting cotton mounting groove of the loosening section, and at least one air inlet groove is connected with the loosening section, so that the oil-conducting cotton and the atomizer inner sleeve form a whole.

[0007] Furthermore, four axially penetrating air inlet grooves are evenly distributed on the side wall of the atomizing inner sleeve, and at least two symmetrically arranged air inlet grooves are connected to the relaxation section of the oil guide cotton installation groove. In this way, since at least two air inlet grooves are symmetrically arranged and the air flow distribution rates in the two air inlet grooves are consistent, the smoke in the atomizing cavity at the bottom of the air inlet groove can be taken away more fully.

[0008] Furthermore, a raised upper oil-joint bone is provided on the clamping section for partially holding the oil-conducting cotton against the atomizing outer sleeve, thereby reducing the friction between the oil-conducting cotton and the atomizing outer sleeve and preventing the oil-conducting cotton from being retained in the atomizing outer sleeve when the oil-conducting cotton is replaced and the atomizing inner sleeve is pulled out; a raised lower oil-joint bone is provided on the relaxation section for shaping the oil-conducting cotton so that the relaxed oil-conducting cotton is wavy in shape, thereby enhancing the adhesion of the smoke oil in the shape, thereby reducing the flow rate of the smoke oil at this location when no smoking is taking place, and preventing the ultrasonic atomizing sheet from being soaked in the smoke oil. In addition, since the air inlet groove is connected to the relaxation section, when smoking, the adhesion of the smoke oil on the wavy oil-conducting cotton at this location is overcome by the force of the gas flow, making the smoke oil flow faster, thereby preventing the reduction of smoke volume due to insufficient supply of smoke oil and the phenomenon of dry burning and cracking of the ultrasonic atomizing sheet.

[0009] Furthermore, a boss for sealing and clamping the ventilation tube is provided in the middle of the inner cavity of the atomizer inner sleeve, and an air outlet cavity is provided in the lower part of the inner cavity of the atomizer inner sleeve below the boss, so that the smoke oil splashed during ultrasonic atomization condenses in the air outlet cavity, and the user is not easy to inhale the smoke oil.

[0011] Furthermore, a support portion is provided on the upper portion of the inner wall of the atomizing outer sleeve, a step is provided on the top of the outer wall of the atomizing inner sleeve, and the step is clamped and fixed on the support portion, thereby realizing a fixed connection between the atomizing inner sleeve and the atomizing outer sleeve.

[0012] Furthermore, a top ring is provided at the lower portion of the inner wall of the atomizing sleeve for resisting the upper surface electrode of the ultrasonic atomizing sheet to form an electrical connection, and a yield portion is provided at the outer periphery of the top ring for preventing the side wall of the ultrasonic atomizing sheet from being squeezed and broken, so that the assembled ultrasonic atomizing sheet is only subjected to the resisting force of the top ring.

[0013] In order to solve the above technical problems, the present invention also provides an electronic cigarette atomizer, which includes an oil bin device and a nozzle device which are connected to each other and can rotate relatively, an oil bin is arranged inside the oil bin device, a second air inlet channel and a nozzle are arranged on the nozzle device, the above electronic cigarette atomizer core is arranged in the oil bin device, and a ventilation pipe is arranged between the nozzle and the boss of the atomization inner sleeve, a third air inlet channel is arranged between the outer wall of the ventilation pipe and the nozzle device and the oil bin device, and the second air inlet channel is connected to the first air inlet channel via the third air inlet channel.

[0015] 1. With the help of airflow power during smoking, the flow speed of the oil on the oil-guiding cotton is increased, and the replacement of gas and oil in the sealed oil tank is accelerated to prevent the phenomenon of insufficient oil supply during smoking;

[0016] 2. A smoke oil blocking structure (lower oil section bone) is arranged at a position corresponding to the oil guide section where the oil guide cotton realizes effective oil guide, so as to prevent excessive smoke oil from being introduced into the ultrasonic atomization sheet when not smoking, thereby preventing the ultrasonic atomization sheet from being soaked in smoke oil, thereby affecting the amount of smoke in the first puff when smoking.

[0027] A first oil passage 11 connected to the oil outlet of the oil tank 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 for resisting the upper surface electrode of the ultrasonic atomizing sheet 6 is provided on the lower portion of the inner wall, 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.

[0028] A step 21 is provided at the top of the outer wall of the atomizer inner sleeve 2. Four air inlet grooves 22 are evenly distributed on the side wall of the atomizer inner sleeve 2, which are axially penetrated and consistent with the flow direction of the smoke oil flowing into the atomizer chamber 3. In this way, the air inlet grooves 22 are located on the inner side of the first oil-passing port 11, which can better utilize the force of the airflow. The oil-guiding cotton installation grooves 23 are symmetrically arranged on the outer wall of the atomizer inner sleeve 2, and the upper part of the oil-guiding cotton installation grooves 23 is provided with a clamping section 231 for clamping the oil-guiding cotton 4, and the lower part is provided with a relaxation section 232 whose depth is greater than the clamping section 231, and the two air inlet grooves 22 are arranged corresponding to the oil-guiding cotton installation grooves 23 and are penetrated with the relaxation section 232. A raised upper oil-joint bone 2311 is provided on the clamping section 231, which is used to partially hold the oil-conducting cotton 4 against the atomizing outer sleeve 1, thereby reducing the friction between the oil-conducting cotton 4 and the atomizing outer sleeve 1, and preventing the oil-conducting cotton 4 from being retained in the atomizing outer sleeve 1 when the oil-conducting cotton 4 is replaced and the atomizing inner sleeve 2 is pulled out; a raised lower oil-joint bone 2321 is provided on the loosening section 232, which is used to shape the oil-conducting cotton 4, so that the loosened oil-conducting cotton 4 is in a wavy shape, thereby enhancing the adhesion of the smoke oil in the shape, thereby reducing the flow rate of the smoke oil in this place when there is no smoking, and preventing the ultrasonic atomizing sheet 6 from being soaked in smoke oil. In addition, since the air inlet groove 22 is connected to the loosening section 232, when smoking, the adhesion of the smoke oil on the wavy oil-conducting cotton 4 can be overcome under the action of gas flow, so that the smoke oil flows faster, thereby preventing the reduction of smoke volume due to insufficient smoke oil during smoking and the phenomenon of dry burning and cracking of the ultrasonic atomizing sheet. A boss 24 for sealing and clamping the atomizer vent pipe 9 is provided in the middle of the inner cavity of the atomizer inner sleeve 2. The inner cavity of the atomizer inner sleeve 2 below the boss 24 is set as an air outlet cavity 25, so that the smoke oil splashed by the ultrasonic atomizer sheet 6 during ultrasonic atomization is condensed in the air outlet cavity 25, making it difficult for users to inhale the smoke oil.

[0029] An atomizing chamber 3 is arranged between the ultrasonic atomizing sheet 6 and the bottom of the atomizing inner sleeve 2. When the vent pipe 9 is inserted into the boss 24 of the atomizing inner sleeve 2 and the outer wall of the vent pipe 9 is clamped and sealed by the boss 24, the intake airflow can only enter the atomizing chamber 3 from the four intake grooves 22, and then pass through the atomizing surface of the ultrasonic atomizing sheet 6 to take away the smoke, and then discharge through the air outlet cavity 25 and the vent pipe 9. In this way, since the four intake grooves are evenly distributed and the divided amount of the intake airflow entering the four intake grooves is consistent, the smoke in the atomizing chamber 3 can be taken away more fully.

[0030] When assembling the atomizer core, first insert the U-shaped oil-guiding cotton 4 with the cotton-compression spring 5 placed in the middle into the oil-guiding cotton installation groove 23 from the bottom of the atomizer inner sleeve 2 upward, so that the two ends of the oil-guiding cotton 4 are respectively sleeved in the oil-guiding cotton installation grooves 23 on both sides of the atomizer inner sleeve 2, so that the oil-guiding cotton 4 and the atomizer inner sleeve 2 form a whole; then the atomizer inner sleeve 2 equipped with the oil-guiding cotton 4 is inserted into the atomizer outer sleeve 1 through the insertion port 12, and is clamped with the inner wall of the atomizer outer sleeve 1, so that the fixation of the oil-guiding cotton 4 is more stable, and the step 21 is clamped and fixed on the support portion 1 3, the fixed connection between the atomizing inner sleeve 2 and the atomizing outer sleeve 1 is realized, and the loosening section 232 is aligned with the oil port 11, so that the oil-conducting cotton 4 can fully store and conduct oil; finally, the ultrasonic atomizing sheet 6, the elastic insulating seat 7 and the electrode assembly 8 are placed in sequence at the bottom of the oil-conducting cotton 4, and the inner wall top ring 14 of the atomizing outer sleeve 1 is pressed against the upper surface electrode of the ultrasonic atomizing sheet 6, the inner wall bottom of the atomizing outer sleeve 1 is connected to the conductive bottom ring 83 of the electrode assembly 8 through threads, and the lower surface electrode of the ultrasonic atomizing sheet 6 is electrically connected to the elastic electrode 81 of the electrode assembly 8. The above assembly method is only one option. Obviously, the ultrasonic atomizing sheet 6, the elastic insulating seat 7 and the electrode assembly 8 can also be installed in the lower part of the inner cavity of the atomizing outer sleeve 1, and then the atomizing inner sleeve 2 equipped with the oil-conducting cotton 4 is inserted into the atomizing outer sleeve 1, and clamped with the inner wall of the atomizing outer sleeve 1.

[0031] like Figure 5 , Figure 6 As shown, an embodiment of the electronic cigarette atomizer of the present invention includes an oil bin device A for accommodating the above-mentioned atomizing core C, and the oil outlet A1 of the oil bin device A is connected to the first oil outlet 11 on the atomizing sleeve 1, so that the smoke oil flows to the oil guide cotton 4 through the second oil outlet 31 and the first oil outlet 11, and then reaches the atomizing surface of the ultrasonic atomizing sheet 6 through the oil guide cotton 4, thereby forming smoke. A suction nozzle device B is arranged on the top of the oil bin device A, and a second air inlet channel B1 and a suction nozzle B2 are arranged on the suction nozzle device B. A ventilation pipe 9 is arranged between the suction nozzle B2 and the air outlet cavity 25 of the atomizing core C, and a third air inlet channel B3 is arranged between the outer wall of the ventilation pipe 9 and the suction nozzle device B and the oil bin device A, and the second air inlet channel B1 is connected to the air inlet groove 22 through the third air inlet channel B3.
