DETAILED DESCRIPTION OF THE EMBODIMENTS

Embodiments of the present disclosure are described more fully hereinafter with reference to the accompanying drawings. The various embodiments of the present disclosure may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the present disclosure to those skilled in the art.

It will be understood that when an element is referred to as being “fixed” to another element, it can be directly fixed to the other element or intervening elements may be present. Also, when an element is referred to as being “connected” or “coupled” to another element, it can be directly connected or coupled to the other element of intervening elements may be present. As used herein, the terms “inside”, “outside”, “left”, “right” and the like are merely for the illustrative purpose.

Referring toFIG. 1, an electronic cigarette according to an embodiment includes an atomizing device10and a power device20. After the atomizing device10and the power device20are assembled, the power device20can supply power to the atomizing device10, such that the atomizing device10atomizes e-liquid to generate smoke for an user to smoke.

In some embodiments, the atomizing device10includes a casing11, an atomizing component12, and a liquid storage component13. The atomizing component12is connected to the liquid storage component13, and is received in the casing11together with the liquid storage component13. A liquid storage cavity A used to store the e-liquid is formed in the liquid storage component13. Normally, the liquid storage cavity A is formed around the atomizing component12, and the e-liquid in the liquid storage cavity A can flow into the atomizing component12, and is then atomized by the atomizing component12to generate smoke.

A smoke channel11afor the smoke to flow out is formed in the casing11. The smoke channel11ais in communication with a portion of the atomizing component12where the e-liquid is atomized, such that the smoke can flow out through the smoke channel11afor user to inhale.

As shown inFIG. 1, the atomizing component12includes a fixing tube121, a liquid absorbing member122, and a heating member123.

A liquid inlet121afor the e-liquid to flow into the fixing tube121is formed on the fixing tube121. The liquid absorbing member122is located in the fixing tube121, such that the e-liquid flowing into the fixing tube121can be absorbed using the capillary effect of the liquid absorbing member122. The liquid absorbing member122can be a tubular liquid absorbing cotton, or a tubular porous ceramic body.

The heating member123is located in the liquid absorbing member122, such that the e-liquid absorbed by the liquid absorbing member122is heated and atomized by the heat generated by heating member123. The heating member123can be at least one of a heating coating, a heating circuit, a heating sheet, and a heating mesh.

In the aforementioned embodiment, an end121bof the fixing tube121away from the power device20shrinks (having a less diameter) and is in communication with the smoke channel11a. When the e-liquid absorbed by the liquid absorbing member122is heated by the heating member123, the e-liquid is atomized into smoke, therefore, when the user inhales at the smoke channel11a, the smoke enters the smoke channel11athrough the fixing tube121, then flows out of the smoke channel11aand is inhaled by the user.

Also referring toFIG. 1, in some embodiments, the liquid storage component13includes a sleeve body131and a cover body132. A bottom of the sleeve body131is sleeved on the fixing tube121, and an annular cavity (i.e., the liquid storage cavity A) is formed between the sleeve body131and the fixing tube121. It should be noted that, after the sleeve body131is sleeved on the fixing tube121, the liquid inlet121aon the fixing tube121is in communication with the liquid storage cavity A. In other words, the liquid inlet121ais located on a portion of the fixing tube121where it can be soaked by the e-liquid, such that the e-liquid in the liquid storage cavity A can enter the fixing tube121through the liquid inlet121a.

In some embodiments, the cover body132covers a top of the sleeve body131, so as to seal the liquid storage cavity A. The cover body132has a through hole allowing the end121bof the fixing tube121to extend through. Therefore, when the cover body132is covered at the top of the sleeve body131, the end121bof the fixing tube121communicates with the smoke channel11athrough the through hole on the cover body132. The cover body132can be made of a soft silicone material, such that the cover body132has good sealing effects between the sleeve body131and the fixing tube121.

Also referring toFIG. 1, in some embodiments, the power device20includes a housing21, a stand22, an air pressure sensor23, a control circuit (not shown), and a battery24.

In some embodiments, a bottom of the atomizing device10is inserted into the housing21, so as to realize the assembly of the electronic cigarette. Of course, the atomizing device10can be assembled with the power device20by other detachable means such as threading or magnetic adsorption. For example, the stand22can be provided with a magnet member such as a magnet27, such that when the atomizing device10is assembled to the power device20, the atomizing device10can be fixed to the power device20by the magnetic force of the magnet27.

In some embodiments, the atomizing device10and the power device20can implement an electrical connection between the battery24and the heating member123by using a contact means at the junction therebetween.

Specifically, the heating member123is connected to an electrical contact15through an electrical connector123asuch as a wire, and the electrical contact15is mounted on one end of the atomizing device10adjacent to the power device20through the mounting base14. Correspondingly, the stand22is provided with a conductive probe25corresponding to the electrical contact15, and the conductive probe25is electrically coupled to the battery24. Therefore, after the atomizing device10and the power device20are assembled, the conductive probe25is in contact with the electrical contact15to realize the electrical connection between the heating member123and the battery24.

Also referring toFIG. 1, the air pressure sensor23and battery24are located on the stand22, and are assembled into the housing21together with the stand22. The stand22and the housing21can be sealed by a sealing member21atherebetween, such as a sealing ring. The battery24can be a rechargeable battery for multiple use, it has good endurance performance, and can be used for a long time to meet the long-term smoking requirements.

The housing21has an air inlet20acorresponding to a bottom of the atomizing device10. Specifically, a gap is formed between the bottom of the atomizing device10and the stand22of the power device20when the atomizing device10and the power device20are assembled. Therefore, when the air inlet20ais located in a position corresponding to the gap, during the smoking process of the user, an external airflow can enter the gap between the atomizing device10and the power device20through the air inlet20a. Correspondingly, the suction effect generated by the user's inhalation will form a negative pressure at the junction between the atomizing device10and the power device20, such that the negative pressure can be detected by the air pressure sensor23, and it is possible to know whether the user is using the electronic cigarette for smoking.

The control circuit is located in the housing21. The air pressure sensor23can be electrically coupled to the control circuit, such that the control circuit can adjust the operation state according to the negative pressure detected by the air pressure sensor23, that is, whether or not the atomizing device10heats or atomizes the e-liquid. For example, when the user does not inhale the smoke, there is little air flow at the junction between the atomizing device10and the power device20, which is insufficient to form a negative pressure, such that the negative pressure detected by the air pressure sensor23will be lower than a preset threshold for the electronic cigarette operation, and the control circuit controls the electronic cigarette to be in an inactive state. Correspondingly, when the user inhales the smoke, the external air flows into the housing21through the air inlet20aand forms a negative pressure at the junction between the atomizing device10and the power device20, the air pressure sensor23detects that the negative pressure is higher than the preset threshold value for the electronic cigarette operation, such that the electronic cigarette operates to generate smoke for the user to smoke. According to this configuration, the control of the electronic cigarette is extremely simplified, and the smoke is generated by atomizing the e-liquid only when the user inhales.

In some embodiments, the stand22has a vent hole23ain communication with the air pressure sensor23. When the user inhales the smoke through the smoke channel11a, a negative pressure is generated at the vent hole23adue to the suction effect.

As shown inFIG. 1, the dashed arrows schematically illustrate the flow path of the airflow during use of the electronic cigarette. Specifically, when the user inhales smoke through the smoke channel11a, the external air flows into the housing21through the air inlet20a, and generates a suction effect to form a negative pressure at the vent hole23a, such that the air pressure sensor23in communication with the vent hole23acan detect the negative pressure generated by smoking of the user. The existence of the negative pressure indicates that the user is smoking, such that the control circuit adjusts the operation state of the electronic cigarette according to the negative pressure detected by the air pressure sensor23, and only operates when the user is smoking. When the user is not smoking, no negative pressure is detected, or the detected negative pressure is lower than the preset threshold for the electronic cigarette operation, the electronic cigarette stops heating and atomizing the e-liquid, and this configuration makes the use of the electronic cigarette extremely convenient.

Referring toFIG. 2toFIG. 4, in some embodiments, a liquid accumulating member26is located at the end of the stand22adjacent to the atomizing device10. A side of the liquid accumulating member26adjacent to the atomizing device10forms a liquid accumulating cavity261, such that when the atomizing device10and the power device20are assembled, the liquid accumulating member26is located between the atomizing device10and the power device20, so as to store the e-liquid exuded from the atomizing device10(i.e., leakage liquid), thereby preventing the leakage liquid from entering the power device20and affecting the normal use of the electronic cigarette.

In some embodiments, the liquid accumulating member26can be made of a silicone material, such that, the liquid accumulating member26has a better sealing performance when it is mounted to the stand22. For example, the liquid accumulating member26made of the silicone material can realize the sealing between the liquid accumulating member26and the stand22, and the sealing between the liquid accumulating member26and the conductive probe25.

As shown inFIG. 3, in some embodiments, the liquid accumulating member26is connected to the stand22by plug-in. The liquid accumulating member26is provided with four inserting pins26aat one side thereof facing the stand22, and four corresponding inserting holes221aare provided on the stand22. The numbers of the inserting pin26aand the inserting hole221acan be two, three, or more, as long as they are equal, such that the liquid accumulating member26can be easily assembled to the stand22by inserting the inserting pins26ainto the corresponding inserting holes221a.

In addition, a mounting groove221is formed on top of the stand22, such that when the liquid accumulating member26is mounted on the stand22, it can be received in the mounting groove221. Furthermore, when the atomizing device10is engaged with the power device20, the liquid accumulating member26does not occupy the assembling space by protruding from the stand22, such that the assembling clearance between the atomizing device10and the power device20is relatively less, the structure is more compact, and the overall volume of the electronic cigarette is reduced.

In some embodiments, the liquid accumulating member26has an extending hole26bcorresponding to the conductive probe25, such that the conductive probe25can extend through the extending hole26band is exposed from the power device20when the liquid accumulating member26is connected to the stand22. Therefore, after the atomizing device10and the power device20are assembled, the conductive probe25can abut against the electrical contact15to realize the electrical connection between the heating member123and the battery24.

Referring toFIG. 2and FIG,3, the liquid accumulating cavity261includes a first liquid accumulating groove261aand a second liquid accumulating groove261bformed on the liquid accumulating member26, and a stepped portion is formed between the grooves. The liquid accumulating member26has a through hole262in communication with the vent hole23a, and the vent hole23aand the through hole262are staggered with each other, so as to prevent the leakage liquid from entering the vent hole23avia the through hole262and blocking the vent hole23a. At the same time, since the through hole262is in communication with the vent hole23a, the negative pressure generated at the junction between the atomizing device10and the power device20during smoking can be detected by the air pressure sensor23at the vent hole23a, so as to ensure the normal operation of the electronic cigarette. It should be noted that, the number of the through hole262can be, but not limited to four, as shown inFIG. 2, the four through holes262are located at four corners of the second liquid accumulating groove261b, respectively.

The position of the through hole262is not limited, and it can be provided according to actual needs, as long as the through hole262and the vent hole23aare staggered with each other, such that the leakage liquid cannot flow into the vent hole23athrough the through hole262. In the illustrated embodiment, as shown inFIG. 2, the through hole262is located in the second liquid accumulating groove261b. In other embodiments, the through hole262can also be provided in the first liquid accumulating groove261a.

As shown inFIG. 3, in some embodiments, two elongated liquid storage grooves222are formed on a top surface of the stand22, and the two liquid storage grooves222are located under the through hole262, so as to collect the e-liquid flown through the through hole262. In the illustrated embodiment, since the through hole262is provided in the second liquid accumulating groove261b, if the leakage liquid continues to flow to the liquid accumulating member26after the first liquid accumulating groove261ais filled, the leakage liquid will flow into the liquid storage grooves222through the through hole262the liquid storage grooves222has a larger space to store more leakage liquid, so as to prevent the vent hole23afrom being blocked.

Referring toFIG. 4, in the illustrated embodiment, a connecting groove223in communication with the two liquid storage grooves222is provided at the top surface of the stand22where the vent hole23ais located. In this way, when the liquid accumulating member26is assembled to the stand22, the liquid accumulating member26will not block the vent hole23a. Since the vent hole23ais in communication with the liquid storage grooves222through the connecting groove223, during the smoking, when the airflow entered from the air inlet20aflows on the surface of the liquid accumulating member26, the air between the liquid accumulating member26and the stand22can be sucked through the through hole262, such that the vent hole23ain communication with the liquid storage grooves222also has a corresponding suction effect so that the negative pressure can be detected by the air pressure sensor23.

It should be noted that, in the aforementioned embodiment, the depth of the connecting groove223is less than the depth of the liquid storage groove222, such that the leakage liquid will not flow into the connecting groove223and block the vent hole23aon the connecting groove223when the liquid storage grooves222stores the leakage liquid. In the illustrated embodiment, during smoking, the airflow in the vent hole23acan flow through the connecting groove223and the liquid storage grooves222in sequence, and then flow out through the through hole262on the liquid accumulating member26, such that the air pressure sensor23in communication with the vent hole23acan detect the negative pressure generated during smoking, and the control circuit can accurately adjust the operation state of the electronic cigarette according to the negative pressure detected by the air pressure sensor23.

Referring toFIG. 1andFIG. 4, in some embodiments, the stand22is provided with a mounting hole224for the air pressure sensor23, the vent hole23aextends into the mounting hole224, such that when the air pressure sensor23is mounted in the mounting hole224, the airflow in the vent hole23acan reach the air pressure sensor23. Therefore, during smoking, the air pressure sensor23can detect the negative pressure generated in the vent hole23a, that is, the user is smoking through the smoke channel11a. At this time, the control circuit will control the atomizing device10to be in the operation state and heat and atomize the e-liquid, so as to generate the smoke for the user to smoke.

In order to make the description succinct, there is no describing of all possible combinations of the various technical features in the foregoing embodiments. It should be noted that there is no contradiction in the combination of these technical features which should be considered as the scope of the description.
