[0027] When the atomization matrix is ​​tobacco oil, the atomizer of the electronic cigarette is equipped with an oil storage chamber for storing tobacco oil. However, due to the fact that the mouth of the tobacco oil bottle on sale may have a variety of thread specifications, the tobacco oil bottles of various specifications on the market cannot all be adapted to one specification of electronic cigarettes. In addition, for electronic cigarettes that use tobacco oil bottles to refill tobacco oil, when the tobacco oil in the oil storage chamber is exhausted, the tobacco oil cannot be refilled into the oil storage chamber through the tobacco oil bottles on sale, or the tobacco oil can only be refilled into the oil storage chamber through a certain specific tobacco oil bottle, which limits the applicability of electronic cigarettes and increases the user's cost of use.

[0028] In view of this, the embodiments of the present disclosure provide an electronic cigarette capable of directly providing e-liquid to an e-liquid storage chamber through a variety of e-liquid bottles, so as to further improve the applicability of the electronic cigarette to different e-liquid bottles.

[0029] Figure 1 is a schematic diagram of an electronic cigarette according to some embodiments of the present disclosure, Figure 2 1 is a cross-sectional view of an electronic cigarette according to some embodiments of the present disclosure. Figure 1 and Figure 2 As shown, the electronic cigarette 100 includes an atomizer 110, a first oil bottle 120, a connector 130 and a power supply assembly 140. The atomizer 110 includes an atomizer core 111, a first oil storage chamber 112 surrounding the atomizer core 111, and a base 113. The first oil storage chamber 112 is used to provide oil to the atomizer core 111 to generate smoke. The base 113 includes an oil channel 114 connected to the first oil storage chamber 112. The electronic cigarette 100 also includes a first oil bottle 120, which includes a second oil storage chamber 121 and a first oil bottle mouth 122. The second oil storage chamber 121 is used to replenish the oil to the first oil storage chamber 112. The first oil bottle mouth 122 has a first external thread 123. The electronic cigarette 100 also includes a connector 130 for connecting the first oil bottle 120 to the oil channel 114. The connecting member 130 includes a first internal thread member 131 and an annular seal 132 . The internal thread of the first internal thread member 131 is configured to cooperate with the first external thread 123 . The annular seal 132 is sleeved on the outside of the first internal thread member 131 and cooperates in the smoke oil channel 114 .

[0030] The atomizer 110 is located at the top of the electronic cigarette 100, and is provided with an atomizer core 111 for heating the oil. The atomizer core 111 is arranged inside the first oil storage chamber 112, so that the oil can be sucked from the surroundings to generate smoke. The base 113 is configured to carry the atomizer core 111, and has an oil channel 114 in the base 113 that is connected to the first oil storage chamber 112, and the oil can be added to the first oil storage chamber 112 through the oil channel 114.

[0031] The function of the connecting member 130 is to connect the first oil bottle 120 to the oil channel 114, so that the second oil storage chamber 121 inside the first oil bottle 120 can replenish the oil in the first oil storage chamber 112. Figure 3 The connecting member 130 may specifically include a first internal threaded member 131 and an annular sealing member 132. The first internal threaded member 131 is generally a sleeve, which is threadedly connected to the first external thread 123 provided at the first smoke oil bottle mouth 122 and fixed to the outside of the first smoke oil bottle mouth 122. The inner diameter of the first internal threaded member 131 can be set according to the outer diameter of the first smoke oil bottle mouth 122, and the outer diameter of the first internal threaded member 131 can be set according to the inner diameter of the position where the smoke oil channel 114 and the first internal threaded member 131 contact each other; the annular sealing member 132 is sleeved on the outside of the first internal threaded member 131 and fits in the smoke oil channel 114, thereby preventing the smoke oil from leaking from the gap between the first internal threaded member 131 and the smoke oil channel 114, and is also conducive to maintaining the connection tightness of the first internal threaded member 131 and the smoke oil channel 114.

[0032] In some embodiments, the annular seal 132 may be a single sealing ring-like structure, thereby facilitating the processing and manufacturing of the annular seal 132 .

[0033] In some embodiments, the annular seal 132 may be a continuous annular structure shaped like a spring, thereby improving the sealing effect of the annular seal 132 to a certain extent.

[0034] Therefore, by providing the first internal threaded part 131 and the annular sealing part 132 to fix the first oil bottle mouth 122 and the oil channel 114 in connection, it is no longer necessary to provide threads at the connection between the atomizer 110 and the oil bottle 120, thereby allowing the atomizer 110 to be connected to different oil bottles to replenish the oil in the first oil storage chamber 112.

[0035] According to some embodiments of the present disclosure, the connector 130 further includes a second internal thread member, which is used for threaded connection with a second e-liquid bottle having a second external thread, and the second external thread is different from the first external thread 123 .

[0036] The second e-liquid bottle is another e-liquid bottle having a different structure from the first e-liquid bottle 120. Specifically, the bottle mouth of the second e-liquid bottle may have a second external thread different from the first external thread 123. In order to achieve the adaptation of the atomizer 110 to the second e-liquid bottle, a second internal threaded member may be provided. The structure of the second internal threaded member is roughly similar to that of the first internal threaded member 131, except that the second internal threaded member is connected to the second external thread 123 at the bottle mouth of the second e-liquid bottle. Similarly, the inner diameter of the second internal threaded member may be set according to the outer diameter of the bottle mouth of the second e-liquid bottle, and the outer diameter of the second internal threaded member may be set according to the inner diameter of the position where the e-liquid channel 114 contacts the second internal threaded member.

[0037] In some embodiments, the outer side of the second internal threaded member is configured so that the annular seal 132 can be sleeved on the second internal threaded member, for example, the outer side of the second internal threaded member is configured the same as the outer side of the first internal threaded member 131. In some other embodiments, the electronic cigarette 100 further includes a second annular seal, which is similar to the annular seal 132 and is also sleeved on the outer side of the second internal threaded member and fits in the smoke oil channel 114, thereby preventing the smoke oil from leaking from the gap between the second annular seal and the smoke oil channel 114 to a certain extent.

[0038] Therefore, by further providing the second internal threaded member, it is advantageous for the atomizer 110 to be compatible with different e-liquid bottles, thereby increasing the applicability of the electronic cigarette 100 to a certain extent.

[0039] Furthermore, the connector 130 may include more internal threaded parts. By providing multiple internal threaded parts, the atomizer 110 can be adapted to a variety of different e-liquid bottles. The multiple internal threaded parts can be configured to be able to engage with the same annular seal 132 to reduce the number of parts of the connector 130.

[0040] According to some embodiments of the present disclosure, the connector 130 further includes an oil bottle seal 133 , which is sleeved on the outside of the first oil bottle opening 122 and located between the first oil bottle opening 122 and the first internal threaded member 131 .

[0041] Therefore, by providing the oil bottle seal 133 between the first oil bottle opening 122 and the first internal threaded member 131 , it is helpful to prevent oil leakage and improve the sealing performance of the electronic cigarette 100 to a certain extent.

[0042] According to some embodiments of the present disclosure, the side wall of the first oil storage chamber 112 is provided with a normally open oil hole 115 for connecting the first oil storage chamber 112 and the second oil storage chamber 121 , and the oil hole 115 is arranged on one side of the side wall close to the mouthpiece of the electronic cigarette 100 .

[0043] like Figure 2 As shown, the oil hole 115 is located on the side wall of the first oil storage chamber 112, and its function is to connect the first oil storage chamber 112 with the second oil storage chamber 121. When the oil in the first oil storage chamber 112 is insufficient, the electronic cigarette 100 is inverted, and the oil in the second oil storage chamber 121 of the oil bottle can enter the first oil storage chamber 112 through the oil hole 115. In the vertical direction, the oil hole 115 is located on the side of the side wall close to the mouthpiece of the electronic cigarette 100. Taking into account that when the user uses the electronic cigarette 100, the mouthpiece is located at a higher position in the vertical direction, arranging the oil hole 115 close to the mouthpiece can, on the one hand, increase the maximum effective liquid level of the oil in the first oil storage chamber 112 (that is, the height of the oil when the first oil storage chamber 112 stores the most oil in the use state), thereby increasing the continuous use time of the user; on the other hand, when the electronic cigarette 100 is inverted, the oil hole 115 is located at a lower position in the vertical direction, and the oil in the second oil storage chamber 121 can flow into the first oil storage chamber 112 through the oil hole 115, thereby realizing the replenishment of oil from the second oil storage chamber 121 to the first oil storage chamber 112.

[0044] In some embodiments, at least a portion of the second oil storage chamber 121 is lower than the first oil storage chamber 112 in the vertical direction, thereby facilitating the flow of tobacco oil from the second oil storage chamber 121 into the first oil storage chamber 112 when the device is inverted.

[0045] In some embodiments, the mouth of the oil bottle 122 is connected to the oil channel 114 in the vertical direction, thereby preventing some oil from remaining in the second oil storage chamber 121 and being unable to flow out when the oil bottle is inverted, and at the same time increasing the speed at which the oil flows into the first oil storage chamber 112.

[0046] Therefore, when the electronic cigarette 100 is inverted, the tobacco oil in the second oil storage chamber 121 can flow into the first oil storage chamber 112 through the oil hole 115 to replenish the tobacco oil for the first oil storage chamber 112, thereby increasing the use time of the electronic cigarette 100.

[0047] According to some embodiments of the present disclosure, the atomizer 110 further includes an oil tank 116 , which is connected to the first oil storage chamber 112 via an oil through hole 115 located on the side wall of the first oil storage chamber 112 , and the oil tank 116 is also connected to the smoke oil channel 114 .

[0048] Therefore, by disposing the oil tank 116 inside the atomizer 110 , the flow rate of the tobacco oil flowing into the first oil storage chamber 112 can be stabilized to a certain extent.

[0049] According to some embodiments of the present disclosure, the wall surface of the oil tank 116 opposite to the first oil bottle opening 122 has a slope section 117 oblique to the first oil storage cavity 112. When the electronic cigarette 100 is inverted, the oil flowing out of the second oil storage cavity 121 will be accumulated on the wall surface of the oil tank 116 opposite to the first oil bottle opening 122. Therefore, setting the wall surface of the oil tank 116 opposite to the first oil bottle opening 122 as the slope section 117 oblique to the first oil storage cavity 112 (that is, the oil through hole 115) is helpful to a certain extent to prevent the accumulation of oil on the wall surface and prevent the oil from entering the first oil storage cavity 112, thereby avoiding the waste of oil.

[0050] According to some embodiments of the present disclosure, the wall surface of the oil bin 116 opposite to the first oil bottle opening 122 is a smooth curved surface, which is helpful to prevent the oil from accumulating on the wall surface and failing to enter the first oil storage cavity 112, thereby avoiding the waste of oil.

[0051] According to some embodiments of the present disclosure, the atomizer 110 further includes an air inlet 151 and an air inlet channel 152 , the air inlet 151 is connected to the atomization core 111 through the air inlet channel 152 , and at least a portion of the air inlet channel 152 extends in a vertical direction.

[0052] When the user uses the electronic cigarette 100, due to the suction of the human mouth at the mouthpiece, negative pressure is formed at the mouthpiece, thereby establishing a gas flow path of "air inlet 151-air inlet channel 152-atomizer core 111-mouthpiece", at which time the smoke will not appear in the air inlet channel 152 or even the air inlet 151, so there will be no condensation of smoke liquid and oil leakage. However, when the suction action of the human mouth at the mouthpiece stops, the pressure inside the entire device returns to the same level, and the remaining part of the smoke may flow out from the atomizer core 111 to the air inlet channel 152 or even the air inlet 151, and the temperature at the air inlet channel 152 or the air inlet 151 is relatively low, which may further form condensation of smoke liquid and cause oil leakage.

[0053] Therefore, by setting at least a portion of the air inlet channel 152 to extend in the vertical direction, under the action of gravity, the air inlet channel 152 extending in the vertical direction hinders the possible condensed smoke liquid from continuing to move toward the air inlet 151 to a certain extent, which is helpful to prevent the problem of smoke oil leakage at the air inlet 151.

[0054] According to some embodiments of the present disclosure, the position of the air inlet 151 in the vertical direction is not lower than the position of the top of the atomizer core 111, and the air inlet 151 is connected to the bottom of the atomizer core 111 through the air inlet channel 152. As a result, the length of the air inlet channel 152 extending in the vertical direction is further increased, which to a certain extent hinders the possible condensed smoke liquid from continuing to move toward the air inlet 151, which is conducive to preventing the problem of smoke oil leakage at the air inlet 151.

[0055] According to some embodiments of the present disclosure, oil-absorbing cotton 153 is provided on the wall of the air inlet channel 152. The oil-absorbing cotton 153 is used to absorb condensed smoke liquid that may be generated in the air inlet channel 152, which is helpful to prevent the problem of smoke liquid leakage at the air inlet port 151 to a certain extent.

[0056] According to some embodiments of the present disclosure, the electronic cigarette 100 further includes a power supply assembly 140 for supplying power to the atomizer 110, and the base 113 is further configured to separate the air inlet channel 152 from the power supply assembly 140 in the vertical direction. This helps prevent the condensed smoke liquid that may be generated at the air inlet channel 152 from penetrating to the vicinity of the power supply assembly 140, and to a certain extent avoids the corrosion of the power supply assembly 140 by the condensed smoke liquid.

[0057] According to some embodiments of the present disclosure, the first internal thread member 131 includes a metal material, and the annular sealing member 132 includes a silicone or rubber material.

[0058] According to some embodiments of the present disclosure, see Figure 3 The outer side of the first internal threaded member 131 is provided with a plurality of grooves 134, and the annular seal 132 includes a plurality of sealing rings, each partially embedded in the plurality of grooves 134. Thus, the plurality of sealing rings can be fixed in the vertical direction respectively through the grooves 134, and the sealing effect of the annular seal 132 can be improved to a certain extent.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure, rather than to limit them; although the present disclosure has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present disclosure, and they should all be included in the scope of the claims and specification of the present disclosure.
