The present invention belongs to the technical field of electronic cigarettes, and particularly relates to an ultrasonic liquid electronic cigarette atomizer and an ultrasonic liquid electronic cigarette.
An ultrasonic liquid electronic cigarette atomizer includes an atomization core, a suction nozzle, an air inlet hole, an air inlet tube, an air outlet tube and a liquid chamber, wherein the air inlet hole is communicated with an atomization chamber of the atomization core through the air inlet tube, the atomization chamber of the atomization core is communicated with the suction nozzle through the air outlet tube, and the liquid chamber is used to supply e-liquid to an ultrasonic atomization sheet in the atomization core.
In the existing ultrasonic liquid electronic cigarette atomizer, the air outlet tube is directly connected to the suction nozzle. During smoking, the electronic cigarette is tilted, the end of the suction nozzle is downward, liquid droplets are condensed on the inner wall of the air outlet tube, and the liquid droplets will move toward the suction nozzle with the air flow of smoking under gravity, so the user is likely to suck the liquid droplets, and the smoke taste is poor. At the same time, the air inlet of the existing electronic cigarette is a small hole near the suction nozzle, so the air inlet channel is easily blocked by the hand or mouth, and the user experience is poor.
The present invention is directed to provide an improved ultrasonic liquid electronic cigarette atomizer and an ultrasonic liquid electronic cigarette with respect to the shortcomings of the prior art, where a user hardly sucks liquid droplets, the smoke taste is good, at the same time, an air inlet channel can be prevented from being blocked by the hand or mouth, and the user experience is good.
In order to solve the technical problem that the user easily sucks liquid droplets, the technical solution adopted by the present invention is as follows:
An ultrasonic liquid electronic cigarette atomizer is provided, including an atomization core, a suction nozzle and an air outlet tube, a bottom end of the air outlet tube being communicated with an atomization chamber of the atomization core, a top end of the air outlet tube being communicated with the suction nozzle, wherein the top end of the air outlet tube is communicated with a bottom end of the suction nozzle through a liquid blocking chamber, and the diameter of a top end of the liquid blocking chamber is greater than the diameter of the bottom end of the suction nozzle.
With the above structure, the top end of the air outlet tube is communicated with the bottom of the suction nozzle through the liquid blocking chamber, so that when a person smokes by tilting an electronic cigarette, the smoke first passes through the air outlet tube, the liquid blocking chamber and then reaches the suction nozzle. Because the diameter of the top end of the liquid blocking chamber is greater than the diameter of the bottom end of the suction nozzle, liquid droplets in the smoke accumulate in the liquid blocking chamber without flowing out along an inner side wall of the suction nozzle, which can prevent a user from sucking the liquid droplets and achieve a good smoke taste.
Further, the ultrasonic liquid electronic cigarette atomizer includes a connecting seat between the liquid blocking chamber and the suction nozzle, wherein an air tube is disposed in the connecting seat, the bottom of the air tube extends into the liquid blocking chamber, the side wall of the air tube is not in contact with the side wall of the liquid blocking chamber, and the liquid blocking chamber is communicated with the suction nozzle through the air tube.
With the above structure, the liquid blocking chamber is communicated with the suction nozzle through the air tube, and the air tube extends into the liquid blocking chamber and is not in contact with the inner wall of the liquid blocking chamber, thereby further blocking the liquid droplets in the liquid blocking chamber from entering the user's mouth through the suction nozzle, and improving the smoke taste and user experience.
Further, in order to solve the technical problem that the air inlet channel is easily blocked by the hand or mouth, the technical solution adopted by the present invention is that the ultrasonic liquid electronic cigarette atomizer further includes an air inlet tube, wherein one end of the air inlet tube is communicated with the atomization chamber of the atomization core, and the other end of the air inlet tube is communicated with the outside through an annular air inlet channel formed along the circumference of the side wall of the atomizer.
Since the air inlet channel is formed along the circumference of the side wall of the atomizer, the air inlet channel can be prevented from being blocked by the hand or mouth to affect the smoking effect.
As a preferred mode, a liquid chamber cover is disposed between the connecting seat and the air outlet tube, and the liquid blocking chamber is disposed at the top of the liquid chamber cover.
As a preferred mode, an annular air inlet channel surrounding the side wall of the atomizer is formed between the bottom of the suction nozzle and the connecting seat, and the air inlet channel is communicated with the atomization chamber of the atomization core through the air inlet tube.
As a preferred mode, the connecting seat is detachably connected to the liquid chamber cover.
The connecting seat is detachably connected to the liquid chamber cover, and when the atomizer is used multiple times or used for a long time, the connecting seat can be detached, and then the liquid blocking chamber is cleaned, so that the atomizer is more hygienic and liquid droplets can be further prevented from being sucked.
As a preferred mode, the atomization core is detachably connected to the bottom of the air outlet tube.
The atomization core is detachably connected to the air outlet tube, so that the atomization core is more convenient to replace, and the use cost is reduced.
Further, an air chamber is formed at the bottom of the suction nozzle, the connecting seat is provided with an air inlet, and the air inlet channel, the air chamber, the air inlet, the air inlet tube, and the atomization chamber of the atomization core are communicated in sequence.
During smoking, air enters the air chamber from the annular air inlet channel, and then enters the air inlet tube through the air inlet in the connecting seat.
Further, the ultrasonic liquid electronic cigarette atomizer includes a liquid chamber, wherein the atomization core includes an ultrasonic atomization sheet and a liquid guiding structure, and the ultrasonic atomization sheet is communicated with the liquid chamber through the liquid guiding structure.
Based on the same inventive concept, the present invention also provides an ultrasonic liquid electronic cigarette, including the ultrasonic liquid electronic cigarette atomizer. Compared with the prior art, the present invention has the advantages that the user hardly sucks liquid droplets, the smoke taste is good, at the same time, the air inlet channel can be prevented from being blocked by the hand or mouth, and the user experience is good.

The ultrasonic liquid electronic cigarette atomizer further includes a connecting seat 5 between the liquid blocking chamber 4 and the suction nozzle 2, an air tube 6 is disposed in the connecting seat 5, the bottom of the air tube 6 extends into the liquid blocking chamber 4, the side wall of the air tube 6 is not in contact with the side wall of the liquid blocking chamber 4, and the liquid blocking chamber 4 is communicated with the suction nozzle 2 through the air tube 6. The length of the air tube 6 extending into the liquid blocking chamber 4 is 1/15 to ½ of the diameter of the top end of the liquid blocking chamber 4, and does not abut against the bottom of the liquid blocking chamber 4, thereby avoiding sucking liquid caused by the fact that the condensed liquid droplets in the liquid blocking chamber 4 enter the air tube 6.
The liquid blocking chamber 4 is communicated with the suction nozzle 2 through the air tube 6, and the air tube 6 extends into the liquid blocking chamber 4 and is not in contact with the inner wall of the liquid blocking chamber 4, thereby further blocking the liquid droplets in the liquid blocking chamber 4 from entering the user's mouth through the suction nozzle 2, and improving the smoke taste and user experience.

The atomization core 1 is detachably connected to the bottom of the air outlet tube 3. When the atomization core 1 needs to be detached, the end of the atomization core 1 that is not inserted into a liquid chamber 12 is held by hand, and then the atomization core 1 can be detached by rotating or pressing or direct pulling, so that the atomization core 1 is more convenient to replace, and the use and maintenance costs are reduced. An air chamber 10 is formed at the bottom of the suction nozzle 2, the air chamber 10 is a space enclosed after the bottom of the suction nozzle 2 is connected to the connecting seat 5, and the connecting seat 5 is provided with an air inlet 11 communicated with the air chamber 10. Therefore, the air chamber 10 can be used to prevent foreign impurities entering the air inlet 11. The air inlet channel 8, the air chamber 10, the air inlet 11, the air inlet tube 7, and the atomization chamber of the atomization core 1 are communicated in sequence. During smoking, air enters the air chamber 10 from the annular air inlet channel 8, then enters the air inlet tube 7 through the air inlet 11 in the connecting seat 5, passes through the atomization chamber of the atomization core 1, and enters the mouth from the air outlet tube 3, the liquid blocking chamber 4, the air tube 6, and the suction nozzle 2 in sequence.
