as shown in fig. 10, the assembling steps of the atomizing core are: firstly, an ultrasonic atomizing ring is inserted into an inner hole of a silica gel sleeve, so that the whole silica gel is wrapped on the atomizing ring, then the whole silica gel sleeve component is inserted into an inner hole of an outer sleeve of an atomizing core, then a middle column of an oil guiding cotton is inserted into a middle hole of the ultrasonic atomizing ring, a spring is inserted into a middle hole of the oil guiding cotton, an insulating ring is arranged in a bottom hole of the outer sleeve of the atomizing core, one electrode wire of the atomizing ring is arranged outside the insulating ring, the insulating ring is clamped with the inner wall of an inner sleeve, the other electrode is arranged on the inner hole of the insulating ring, the electrode ring is arranged in the inner hole of the insulating ring, the one electrode wire of the atomizing ring is clamped with an inner control wall of the insulating ring, the outer sleeve of the atomizing core is covered on the surface of the oil guiding cotton, and finally the atomizing core is obtained after the outer sleeve of the atomizing core is in tension fit.
The inner hole of the ultrasonic atomization ring is provided with an elastic piece (spring), and the spring is used for supporting the oil guiding cotton, so that the oil guiding cotton is contacted with the inner wall of the inner hole of the ultrasonic atomization ring, and the phenomenon of burning or self damage caused by poor contact between the ultrasonic atomization ring and the oil guiding cotton during operation is prevented.
The oil guide cotton absorbs tobacco tar in the tobacco tar bin through the through hole on the outer sleeve of the atomizing core, and the oil guide cotton bends and extends to the inner hole of the ultrasonic atomizing ring along the atomizing core close to the suction nozzle end, so that the effect of atomization is effectively prevented from being influenced by too high flowing speed of the tobacco tar.
The bottom department of atomizer is provided with the gas storage chamber, and the air inlet sets up on the gas storage chamber lateral wall and communicates with the atmosphere, prevents that the user from blocking up the air inlet when using the electron cigarette from the finger, also can be used for the tobacco tar that leaks in atomizing core to store, prevents that this tobacco tar seepage from damaging the power to the power part of electron cigarette.
Be provided with the tubaeform air pipe structure on the suction nozzle, make things convenient for this trachea better to flow down condensation tobacco tar, prevent also that the user from inhaling condensation tobacco tar that can be fine.
The spring is used for fixing the oil guide cotton and ensuring good contact between the oil guide cotton and the inner cavity surface of the ultrasonic atomization ring.
The inner wall of ultrasonic atomization ring is main electrode for ultrasonic atomization tobacco tar, in addition, wherein lead to the structure and can set the air current as down admitting air, the air current gets into from the bottom, leads to the structure from bottom to top and give vent to anger in the atomizing ring again, can be more abundant with smog take out, make smog bigger.
The silica gel cover plays the effect of isolated heat, because the ultrasonic atomization ring during operation can produce certain heat, can be isolated with heat through the silica gel cover, avoids the atomizer to send out to scald. In addition, the silica gel sleeve plays a role in sealing tobacco tar, so that the outer ring surface of the atomizing ring is prevented from contacting the tobacco tar and corroding the silver layer. The oil guide cotton is used for guiding tobacco tar from the oil inlet hole of the atomization core to the inner annular surface of the atomization ring.
Therefore, the tobacco tar enters the oil guide cotton through the oil inlet hole, oil is guided upwards, and is guided downwards from the upper part of the silica gel sleeve to the inner wall of the ultrasonic atomization ring, and after turning for a plurality of times, the problem that the atomization ring is too fast in oil seepage and cannot generate fog due to oil soaking can be well prevented.
The gas circuit can enter and exit from the middle through hole of the atomizing ring, so that the smoke is taken away more fully, and the smoke is enlarged.
The radial dimension of the invention can be made smaller and the space utilization rate is higher.
Because the main atomizing surface is arranged on the inner surface of the atomizing ring during atomization, the problem that large particles are directly sprayed upwards to scald the oral cavity can be well avoided.
The piezoelectric ceramic atomizer of the invention has a hollow annular structure, and the section of the piezoelectric ceramic atomizer can have a circular structure, an elliptical structure as shown in fig. 15 and a square structure as shown in fig. 16.
An electronic cigarette comprises a battery assembly and the ultrasonic atomizer; the battery assembly supplies power to the atomizing ring 5 of the ultrasonic atomizer.
