Description

Technical Field

[0001] The present invention belongs to the technical field of electronic cigarettes, and in particular relates to an ultrasonic electronic cigarette atomization core, an atomizer and an ultrasonic electronic cigarette. Background Art

[0002] The existing ultrasonic electronic cigarette includes a power supply unit, an oil supply unit and an atomization core. The atomization core includes an oil guide cotton, an atomization chamber and an ultrasonic atomization sheet. The ultrasonic atomization sheet is arranged in the atomization chamber. The atomization core is also provided with an air inlet connecting the electronic cigarette air inlet and the atomization chamber, and an air outlet connecting the electronic cigarette air outlet and the atomization chamber; the oil supply unit includes an oil tank and an oil outlet hole. The oil tank is connected to the atomization surface of the ultrasonic atomization sheet through the oil outlet hole and the oil guide cotton in turn; the power supply unit is provided with a power supply for supplying power to the electronic cigarette, and a mainboard for controlling the operation of the electronic cigarette.

[0003] When the ultrasonic electronic cigarette is working, the oil in the oil tank is guided to the atomization surface of the ultrasonic atomizer through the oil outlet hole. The ultrasonic atomizer atomizes the oil to produce smoke and fills the atomizer cavity. The airflow enters the atomizer cavity from the air inlet through the air inlet, and the smoke in the atomizer cavity is taken out through the air outlet, the air outlet and the mouthpiece in turn for the user to inhale.

[0004] Existing ultrasonic electronic cigarettes have the following disadvantages:

[0005] First, during the atomization process of the ultrasonic atomizer, part of the e-liquid is not fully atomized into smoke, so that part of the e-liquid splashes in the atomization area of ​​the e-liquid guide cotton. In the prior art, the position of the air inlet for connecting the air inlet duct and the atomization chamber is set arbitrarily, resulting in the splashed e-liquid easily dripping into the air inlet duct through the air inlet, thereby affecting the normal circulation of the airflow.

[0006] Second, in the ultrasonic electronic cigarette controlled by the starter microphone, the sensor head of the starter microphone is set in the starter channel, where the starter channel is connected to the air intake channel. When air flows through the air intake channel, the air pressure in the starter channel changes. After the sensor head of the starter microphone senses the change in air pressure, the ultrasonic electronic cigarette starts to work. If there are oil droplets in the air intake channel, the oil droplets may flow along the air intake channel to the starter channel, and even the microphone may be wetted by the oil, and the starter channel may be blocked, causing the air pressure in the starter channel to not change or change slowly, affecting the sensitivity and service life of the starter microphone.

[0007] Third, the ultrasonic electronic cigarette atomizer is not modularized, and the maintenance and use costs are high. For example, the oil in the oil tank is not in a sealed state and the oil is easy to deteriorate; after the oil guide mechanism or ultrasonic atomizer is damaged, it is difficult to replace and the maintenance cost is high. Summary of the invention

[0008] The object of the present invention is to provide an ultrasonic electronic cigarette atomization core, an atomizer and an ultrasonic electronic cigarette in view of the above-mentioned deficiencies in the prior art.

[0009] In order to solve the technical problem that smoke oil droplets are easily splashed into the air inlet, the technical solution adopted by the present invention is:

[0010] An ultrasonic electronic cigarette atomization core comprises an atomization seat, wherein the atomization seat is provided with oil-conducting cotton, an atomization chamber and an ultrasonic atomization sheet, the ultrasonic atomization sheet is arranged in the atomization chamber, the atomization portion of the oil-conducting cotton contacts the atomization surface of the ultrasonic atomization sheet; the atomization chamber is provided with an air inlet and an air outlet; the air inlet is communicated with an air inlet duct of the electronic cigarette, and the air outlet is communicated with an air outlet duct of the electronic cigarette; the minimum distance between the side wall of the air inlet and the atomization surface of the ultrasonic atomization sheet is greater than the thickness of the atomization portion of the oil-conducting cotton by h.

[0011] With the above structure, since the air inlet of the atomization chamber is higher than the atomization part of the oil guide cotton in contact with the ultrasonic atomization sheet, during the ultrasonic atomization process, it is possible to prevent the oil droplets splashing in the atomization chamber from splashing to the air inlet and entering the air inlet duct to affect the air intake effect.

[0012] As a preferred method, the value range of h is 0.5mm~30mm, and the smoke oil droplets will not splash into the air inlet and the air inlet duct, and will not affect the smoke outflow effect.

[0013] As a preferred embodiment, the air inlet is arranged around the periphery of the ultrasonic atomization sheet, and the axial direction of the air inlet is perpendicular to the ultrasonic atomization sheet.

[0014] As a preferred embodiment, the air outlet is arranged above the central area of ​​the atomizing surface of the ultrasonic atomizing sheet.

[0015] Since the air outlet is arranged above the central area of ​​the atomizing surface of the ultrasonic atomizing sheet, the smoke generated by ultrasonic atomization is directly sent away by the air outlet, thereby reducing the heat loss of the smoke and improving the taste of the smoke.

[0016] Furthermore, a through pipe is provided on the atomizer seat, and the through pipe is connected to the outside and the oil-conducting cotton.

[0017] Corresponding to the above structure, a sealing film for sealing the oil bin is provided on the oil supply unit corresponding to the atomizer core. During the production process, the oil bin of the oil supply unit is pre-injected with smoke oil. When in use, the atomizer core and the oil supply unit are connected. During the connection process, the through pipe on the atomizer core pierces the sealing film, so that the oil bin is connected to the oil guide cotton, and the smoke oil in the oil bin flows from the through pipe to the oil guide cotton, and then is guided to the atomization surface of the ultrasonic atomizer sheet for ultrasonic atomization and smoke production. It can be seen that when the through pipe on the atomizer core does not pierce the sealing film of the oil supply unit, the smoke oil is in a sealed state, so the smoke oil is not easy to deteriorate and is convenient to transport. When smoking is needed, the atomizer core and the oil supply unit are connected, and the sealing film of the oil supply unit is pierced through the through pipe, and the oil circuit is connected, which is convenient to use. When the smoke oil in the oil bin is exhausted, the oil supply unit is removed and replaced with a new one, which is clean and hygienic, and can also avoid the risk of oil leakage caused by multiple oil fillings.

[0018] Furthermore, an elastic seat is provided in the atomizer seat, a through hole is provided in the center of the elastic seat, the oil-conducting cotton includes a bent edge arranged on the side of the atomizing part, the atomizing part passes through the through hole and contacts the atomizing surface of the ultrasonic atomizing sheet, the bent edge is arranged between the top surface of the silicone seat and the top surface inside the atomizer seat, and the top surface of the bent edge is connected to the through pipe.

[0019] With the above structure, the bent edge is arranged between the top surface of the silicone seat and the inner top surface of the atomizer seat, and the top surface of the bent edge is connected with the through pipe, so it is easy to absorb the smoke oil discharged from the through pipe.

[0020] Furthermore, a plurality of air-permeable grooves opposite to the bent edges are formed on the top surface of the elastic seat.

[0021] With the above structure, the bent edge covers the ventilation groove, and the gas outside the oil tank enters the oil tank through the ventilation groove and the through pipe, realizing the replacement of the smoke oil and gas in the oil tank, so that the through pipe can discharge the smoke oil more smoothly, and enough smoke oil is absorbed by the oil guide cotton.

[0022] Based on the same inventive concept, the present invention also provides an ultrasonic electronic cigarette atomizer, including an oil supply unit, the oil supply unit includes an oil tank and an oil outlet hole, and is characterized in that it also includes the ultrasonic electronic cigarette atomizer core, the atomizer core is detachably connected to the oil supply unit; the oil tank is connected to the oil guide cotton through the oil outlet hole.

[0023] In order to solve the technical problem that the e-liquid is easy to deteriorate, a through pipe is provided on the atomizer seat, and a sealing film that can be pierced by the through pipe is provided in the oil outlet hole; when the oil supply unit is connected to the atomizer core, the through pipe extends into the oil outlet hole and pierces the sealing film, and at the same time the through pipe connects the oil tank and the oil guide cotton.

[0024] Based on the same inventive concept, the present invention also provides an ultrasonic electronic cigarette, including a power supply unit, which is characterized in that it also includes the ultrasonic electronic cigarette atomizer, and the power supply unit is detachably connected to the atomizer.

[0025] With the above structure, the ultrasonic electronic cigarette is divided into three modules: power supply unit, oil supply unit and atomization core. Each module can be disassembled from each other. It has a simple structure, low use and maintenance costs, is easy to use, and improves user experience.

[0026] In order to solve the technical problem that smoke oil droplets easily enter the starting channel and affect the sensitivity and service life of the starting microphone, the power supply unit includes a shell, a starting channel and a starting microphone for controlling the operation of the electronic cigarette are arranged in the shell, and the sensing head of the starting microphone is arranged in the starting channel; when the power supply unit is connected to the atomizer, the air inlet channel is connected to the starting channel.

[0027] When using an ultrasonic electronic cigarette, the starter channel is aligned and connected with the air intake channel. When smoking, the air pressure in the air intake channel and the starter channel changes, thereby triggering the starter microphone to start the electronic cigarette. Since the smoke oil droplets will not enter the air intake channel from the air inlet, they will not enter the starter channel, thus ensuring the working sensitivity and service life of the starter microphone.

[0028] Furthermore, the shell is provided with a slot, and the atomizer seat is provided with a guide bone matched with the slot.

[0029] With the above structure, the guide bone is used as the hand-held part for installing the atomizer core into the power supply unit. When connecting the atomizer core and the power supply unit, the guide bone is inserted into the slot to ensure that the starting channel and the air inlet channel are aligned and connected, so as to prevent the two from being misaligned and affecting the sensitivity of the starting microphone.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] First, the smoke oil droplets produced by atomization will not enter the air inlet duct through the air inlet of the atomization chamber, ensuring the air intake effect. At the same time, it can also prevent the user from inhaling the smoke oil droplets in the air inlet duct when smoking again.

[0032] Second, the smoke oil droplets produced by atomization will not enter the starting duct through the air intake duct, and the starting microphone has high sensitivity and long service life.

[0033] Third, the e-liquid is in a sealed state, the e-liquid is not easy to deteriorate, the structure is simple, the use is convenient, and the use and maintenance costs are low.

[0034] Fourth, it adopts modular design, which is easy to disassemble and assemble, and has low use and maintenance costs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0045] like Figures 1 to 9As shown, the ultrasonic electronic cigarette atomization core 12 includes an atomization seat 1, in which an oil-conducting cotton 2, an atomization chamber 3 and an ultrasonic atomization sheet 4 are arranged, the ultrasonic atomization sheet 4 is arranged in the atomization chamber 3, and the atomization part 201 of the oil-conducting cotton 2 is in contact with the atomization surface of the ultrasonic atomization sheet 4; the atomization chamber 3 is provided with an air inlet 5 and an air outlet 6; the air inlet 5 is connected to the air inlet 7 of the electronic cigarette, and the air outlet 6 is connected to the air outlet 8 of the electronic cigarette; the minimum distance between the side wall of the air inlet 5 and the atomization surface of the ultrasonic atomization sheet 4 is greater than the thickness of the atomization part 201 of the oil-conducting cotton 2 by h. The value range of h is 0.5mm~30mm.

[0046] Since the air inlet 5 of the atomization chamber 3 is higher than the atomization portion 201 of the oil guide cotton 2 in contact with the ultrasonic atomization sheet 4, the oil droplets splashed in the atomization chamber 3 can be prevented from splashing to the air inlet 5 and entering the air inlet duct 7 during the ultrasonic atomization process to affect the air intake effect, and at the same time, it will not affect the smoke carrying out effect.

[0047] The air inlet 7 is arranged around the periphery of the ultrasonic atomizing sheet 4 , the axial direction of the air inlet 7 is perpendicular to the ultrasonic atomizing sheet 4 , and the air inlet 7 axially extends to the bottom of the atomizing core 12 .

[0048] The air outlet 6 is arranged above the central area of ​​the atomizing surface of the ultrasonic atomizing sheet 4. Since the air outlet 6 is arranged above the central area of ​​the atomizing surface of the ultrasonic atomizing sheet 4, the smoke generated by ultrasonic atomization is directly sent away by the air outlet 6, thereby reducing the heat loss of the smoke and improving the taste of the smoke.

During the production process, the oil tank 13 of the oil supply unit 10 is pre-injected with tobacco oil. When in use, the atomizer core 12 and the oil supply unit 10 are connected. During the connection process, the through tube 102 on the atomizer core 12 pierces the sealing film 1402, so that the oil tank 13 is connected to the oil-conducting cotton 2, and the tobacco oil in the oil tank 13 flows from the through tube 102 to the oil-conducting cotton 2, and then is guided to the atomization surface of the ultrasonic atomizer sheet 4 for ultrasonic atomization and smoke production. It can be seen that when the through tube 102 on the atomizer core 12 does not pierce the sealing film 1402 of the oil supply unit 10, the tobacco oil is in a sealed state, so the tobacco oil is not easy to deteriorate and is convenient to transport. When you need to smoke, connect the atomizer core 12 and the oil supply unit 10, pierce the sealing film 1402 of the oil supply unit 10 through the through pipe 102, and the oil circuit is open, which is convenient to use.

[0051] The top surface of the elastic seat 9 is provided with a plurality of ventilation grooves 902 opposite to the bent edge 202. The bent edge 202 covers the ventilation grooves 902, and the gas outside the oil bin 13 enters the oil bin 13 through the ventilation grooves 902 and the through pipe 102, so that the oil and gas in the oil bin 13 are replaced, so that the through pipe 102 discharges the oil more smoothly, and enough oil is absorbed by the oil guide cotton 2.
