Existing ultrasonic vaping vaporizers have the following disadvantages:

First, in the existing ultrasonic electronic cigarette atomizer, the distance between the oil outlet hole of the oil tank and the oil guide mechanism is very close, or the oil guide mechanism is directly placed in the oil tank, so the e-liquid through the oil guide mechanism causes the ultrasonic atomization chip The speed is very fast, so the ultrasonic atomizing tablet is easily soaked by e-liquid, which affects the atomization effect of the ultrasonic atomizing tablet, and the user experience is poor.

Second, the ultrasonic electronic cigarette atomizer is not modularized, and the maintenance and use costs are high. For example, the e-liquid in the oil tank is not in a sealed state, and the e-liquid is easy to deteriorate; after the oil guiding mechanism or the ultrasonic atomizing sheet is damaged, it is difficult to replace , the maintenance cost is high.

SUMMARY OF THE INVENTION

The purpose of the present invention is to provide a modular ultrasonic electronic cigarette core, atomizer and ultrasonic electronic cigarette in view of the above-mentioned deficiencies of the prior art, the e-liquid is in a sealed state, the e-liquid is not easy to deteriorate, the structure is simple, and the use is convenient , The use and maintenance costs are low; it can improve the amount of smoke and the taste of smoke, and prevent the phenomenon of dry burning of the ultrasonic atomizer. The ultrasonic atomizer has a long service life, low use cost and good user experience.

For solving the above-mentioned technical problems, the technical scheme adopted in the present invention is:

An ultrasonic electronic cigarette atomizing core includes a base, an oil guiding mechanism and an ultrasonic atomizing sheet, the oil guiding mechanism and the ultrasonic atomizing sheet are fixed in the base, and the oil guiding mechanism is in contact with the atomizing surface of the ultrasonic atomizing sheet, and the The structure is characterized in that the base is also provided with a drainage column, and the drainage column is provided with an oil inlet hole that communicates with the outside world and the oil guiding mechanism.

With the above structure, the e-liquid is guided to the oil guide mechanism through the oil inlet hole on the drainage column, and the time for the e-liquid to flow to the oil guide mechanism is slowed down, so that the ultrasonic atomizer can be prevented from being damaged by the e-liquid when not smoking. Immersion affects the first puff of smoke when smoking.

The time for the e-liquid to pass through the oil inlet hole of the drainage column is related to the height of the oil hole. When the height of the oil inlet hole is higher, the time for the e-liquid to pass through the oil inlet hole is longer; the atomizing core is used in conjunction with the oil supply unit , when the e-liquid in the oil supply unit is led to the oil guide mechanism through the oil inlet hole, each time a certain amount of e-liquid discharged through the oil inlet hole is accompanied by an equal amount of air from the oil inlet hole to the supply in the form of air bubbles. Replacement in the oil unit, so when smoking, the air pressure in the atomizing core changes, making it easier for the air to be squeezed into the oil supply unit, so that the oil inlet hole discharges the e-liquid faster, preventing the ultrasonic atomizing sheet Dry burning caused by insufficient e-liquid during ultrasonic atomization; when not smoking, because the air pressure in the atomizing core is balanced with the air pressure in the oil supply unit, there is no external force to impact the adhesion of e-liquid in the oil inlet hole, so The e-liquid in the oil inlet hole is not easy to flow to the oil guiding mechanism, so it can prevent or reduce the phenomenon of being soaked by e-liquid when the ultrasonic atomizer is not working.

Further, an oil guiding groove communicated with the oil inlet hole is also provided on the outer end surface of the drainage column.

With the above structure, after the oil supply unit is connected to the atomizing core, the outer end face of the drainage column extends into the oil supply unit to contact the e-liquid, and during the process of guiding the oil through the oil inlet hole, the air enters the oil supply in the form of air bubbles. The oil guide groove can discharge or puncture the air bubbles locked at the end of the oil inlet hole, so as to guide the e-liquid in the oil supply unit to the oil inlet hole, so that the oil guide is smoother.

The outer end is clamped in the limiting groove.

With the above structure, the oil guiding mechanism straddles the top of the first cavity, that is, the oil guiding mechanism corresponding to the first cavity is in a relaxed state, so the oil guiding mechanism can store more e-liquid, and the end of the oil guiding mechanism is clamped at the end of the first cavity. In the limit groove, the phenomenon of wrinkling or falling off of the oil guiding mechanism can be prevented in the process of assembling the oil guiding mechanism.

Further, the side wall of the first cavity is also provided with a groove.

With the above structure, after the oil guide mechanism is assembled on the top surface of the atomizing seat, the oil guide mechanism at the corresponding groove is loosened, so when smoking, the air can enter the oil inlet hole through the groove, preventing the oil supply unit from being damaged. The replacement speed of the e-liquid and the air is slow, which causes the insufficient supply of e-liquid to dry the ultrasonic atomizer.

Further, an air inlet and an air outlet are provided on the base, and both the air inlet and the air outlet are communicated with the outside world and are communicated with the atomizing surface of the ultrasonic atomizing sheet.

With the above structure, the air intake holes and the air outlet holes are both arranged on the base, and the base is formed by a mold at one time, so the independent parts of the air inlet holes or the air outlet holes are reduced, and when assembling, the air inlet holes and the air outlet holes are both. It communicates with the atomizing surface of the ultrasonic atomizing sheet in the base, that is, when smoking, the airflow enters from the air inlet and the smoke is brought out from the air outlet. Therefore, the atomizing core uses few parts, low cost, and the smoke is discharged in time, which improves the user experience. experience.

As a preferred manner, the edge portion of the sealing plug is a thin-walled portion whose thickness is smaller than that of the central region of the sealing plug, and the thin-walled portion is connected to the inner side wall of the oil outlet hole.

The design of the thin-walled part makes it easy for the drainage column to pierce the thin-walled part, so that the sealing plug is separated from the oil outlet hole, so that the oil tank and the oil inlet hole are connected.

Detailed ways

As shown in FIGS. 1 to 14 , the ultrasonic electronic cigarette atomizing core 11 includes a base 1, an oil guiding mechanism 2 and an ultrasonic atomizing sheet 3. The oil guiding mechanism 2 and the ultrasonic atomizing sheet 3 are fixed in the base 1, and the oil guiding mechanism 2 and the ultrasonic atomizing sheet 3 are fixed in the base 1. The mechanism 2 is in contact with the atomizing surface of the ultrasonic atomizing sheet 3 . The base 1 is also provided with a drainage column 107 , and the drainage column 107 is provided with an oil inlet hole 101 that communicates with the outside world and the oil guiding mechanism 2 .

The oil supply unit 9 corresponding to the atomizing core 11 is provided with a sealing plug 17 for sealing the oil tank 10. During the production process, the oil tank 10 of the oil supply unit 9 is pre-injected with e-liquid, and the atomizing core 11 and the In the oil supply unit 9, during the connection process, the drainage column 107 on the atomizing core 11 pierces the sealing plug 17, so that the oil tank 10 is communicated with the oil inlet hole 101, and the e-liquid in the oil tank 10 flows from the oil inlet hole 101 to the oil inlet hole 101. on the oil guiding mechanism 2, and then lead to the atomizing surface of the ultrasonic atomizing sheet 3 for ultrasonic atomization to produce smoke. It can be seen that when the drainage column 107 on the atomizing core 11 does not pierce the sealing plug 17 of the oil supply unit 9, the e-liquid is in a sealed state, so the e-liquid is not easy to deteriorate. When smoking is required, the atomizing core 11 and the oil supply unit 9 are connected, and the sealing plug 17 of the oil supply unit 9 is pierced through the drainage column 107, and the oil passage is connected, which is convenient to use. When the e-liquid in the fuel tank 10 is exhausted, the fuel supply unit 9 is removed and replaced with a new fuel supply unit 9, which is clean and hygienic, and can also avoid the risk of oil leakage caused by multiple fuel injections.

When the drainage column 107 is in communication with the oil tank 10, the e-liquid is guided to the oil guiding mechanism 2 through the oil inlet hole 101 on the drainage column 107, so the e-liquid can be guided to the oil guiding mechanism by controlling the length of the drainage column 107. 2, such as when smoking, the air pressure in the atomizing core 11 changes, so the air is more likely to be squeezed into the oil tank 10, so the oil inlet hole 101 discharges the e-liquid faster, so as to provide sufficient A large amount of e-liquid participates in ultrasonic atomization to meet the user's demand for smoke volume and improve the experience; when not smoking, since the air pressure in the atomizing core 11 and the air pressure in the oil tank 10 are in a state of balance, there is no external force (air pressure change) Impacting the adhesion of the e-liquid in the oil inlet hole, so the e-liquid in the oil inlet hole 101 is not easy to flow to the oil guiding mechanism, so it can prevent or reduce the phenomenon of being soaked by the e-liquid when the ultrasonic atomizer is not working.

The length of the drainage column 107 is 1mm-10mm; the length of the oil inlet hole 101 is 1mm-10mm.

An oil guide groove 1071 communicated with the oil inlet hole 101 is also defined on the outer end surface of the drainage column 107 . The oil guiding groove 1071 can guide the e-liquid in the oil tank 10, such as the oil inlet hole 101, so that the oil guiding is smoother.

The atomizing core 11 is provided with a first cavity 102 corresponding to the oil inlet hole 101 as a spare oil cavity. Since the oil guiding mechanism 2 and the oil inlet hole 101 are both communicated with the first cavity 102, the A part of the e-liquid entering the atomizing core 11 from the oil inlet hole 101 is stored in the first cavity 102 , and a part is absorbed by the oil guiding mechanism 2 . During the use of the electronic cigarette, even if it cannot be guaranteed that there is always e-liquid at the oil outlet 1301 of the oil tank 10 , since part of the e-liquid can be stored in the first cavity 102 , the oil guiding mechanism 2 can transfer the e-liquid in the first cavity 102 . The e-liquid is guided to the ultrasonic atomizing sheet 3 for atomization; at the same time, the oil guiding mechanism 2 straddles the top of the first cavity 102, that is, the oil guiding mechanism 2 corresponding to the first cavity 102 is in a relaxed state, so the guiding mechanism 2 there is in a relaxed state. The oil mechanism 2 can store more e-liquid, which helps to improve the oil guiding speed of the oil guiding mechanism 2 during the ultrasonic atomization process and replenish the e-liquid in time, so it can prevent the ultrasonic atomizing sheet 3 from being in the atomization process to a certain extent. Dry burning due to insufficient supply of e-liquid in the middle, guarantees the amount of smoke and the taste of smoke, prolongs the service life of the ultrasonic atomizer 3, reduces the cost of use, and provides a good user experience.
