[0028] Electronic cigarettes are usually equipped with an oil storage chamber for storing oil, thereby extending the service life of the electronic cigarette. However, when the oil storage chamber supplies a large amount of oil to the electronic cigarette, oil leakage is likely to occur in the oil supply path due to excessive oil pressure. Therefore, it is necessary to provide an electronic cigarette with a stable oil supply pressure to avoid the problem of oil leakage in the electronic cigarette as much as possible.
[0029] In view of this, the embodiment of the present disclosure provides an electronic cigarette that supplies oil to the atomizer core through oil-conducting cotton and oil-storing cotton, thereby avoiding the problem of oil leakage in the oil supply path due to excessive oil pressure when the oil storage chamber supplies a large amount of oil to the electronic cigarette.
[0030] Figure 1 and Figure 2 Schematic diagrams and cross-sectional diagrams of electronic cigarettes in some embodiments. Figure 1 and Figure 2 As shown, the electronic cigarette 100 includes: an oil storage chamber 110 for storing smoke oil; an atomizer core 120 for heating the smoke oil to generate smoke; an oil storage cotton 130 for providing smoke oil to the atomizer core 120, and the oil storage cotton 130 is arranged on the outside of the atomizer core 120; and an oil guide cotton 140, wherein the first end of the oil guide cotton 140 contacts the smoke oil in the oil storage chamber 110, the second end of the oil guide cotton 140 contacts the oil storage cotton 130, and the oil guide cotton 140 and the oil storage cotton 130 abut against each other. Preferably, the oil guide cotton 140 and the oil storage cotton 130 can be set to an interference fit to achieve full contact of the abutting surfaces.
[0031] The function of the oil storage chamber 110 is to store the e-liquid and supply the e-liquid to the atomizer core 120, so as to meet the user's needs for longer use. In order to keep the pressure of the entire oil supply path from the oil storage chamber 110 to the atomizer core 120 within a stable range, the oil supply from the oil storage chamber 110 to the atomizer core 120 is achieved using oil guide cotton 140 and oil storage cotton 130. Specifically, the two ends of the oil guide cotton 140 are in contact with the e-liquid and oil storage cotton 130 in the oil storage chamber 110, respectively, and the two ends of the oil storage cotton 130 are in contact with the oil guide cotton 140 and the atomizer core 120, respectively, thereby forming an oil supply path of "oil storage chamber 110-oil guide cotton 140-oil storage cotton 130-atomizer core 120".
[0032] The oil-conducting cotton 140 and the oil-storing cotton 130 are both porous structures similar to sponges in structure. When in contact with the smoke oil, these porous structures can absorb the smoke oil and guide the smoke oil to flow inside the oil-conducting cotton 140 and the oil-storing cotton 130. Since these porous structures are relatively dense, the speed and pressure of the smoke oil flowing therein are relatively stable, thereby avoiding the situation of excessive pressure at a certain point in the oil supply path to a certain extent, which is conducive to reducing the leakage of smoke oil in the electronic cigarette 100. At the same time, the mutual contact between the oil-conducting cotton 140 and the oil-storing cotton 130 can be an interference fit. In the state of interference fit, the oil-conducting cotton 140 and the oil-storing cotton 130 squeeze each other, which is conducive to the flow of smoke oil in the oil-conducting cotton 140 to the oil-storing cotton 130, so that the smoke oil can flow smoothly through the junction of the oil-conducting cotton 140 and the oil-storing cotton 130, and to a certain extent, avoid the occurrence of poor oil supply.
[0033] Therefore, since the oil-conducting cotton 140 and the oil-storing cotton 130 are made of porous materials, the smoke oil can be supplied from the oil storage chamber 110 to the atomizer core 120 through the oil-conducting cotton 140 and the oil-storing cotton 130, so that the pressure of the entire oil supply path from the oil storage chamber 110 to the atomizer core 120 can be maintained within a stable range, which can avoid the problem of oil leakage that may occur in the electronic cigarette 100 during the oil supply process due to excessive oil pressure to a certain extent.
[0034] In some embodiments, the electronic cigarette 100 further includes an oil-conducting cotton mounting tube 150 , at least a portion of the oil-conducting cotton 140 is located in the oil-conducting cotton mounting tube 150 , and a through hole for gas circulation is provided between the oil-conducting cotton 140 and the oil-conducting cotton mounting tube 150 .
[0035] The oil-conducting cotton installation tube 150 is a section of a pipe connected to the internal space of the oil storage chamber 110. At least a portion of the oil-conducting cotton 140 is located in the oil-conducting cotton installation tube 150, thereby providing a fixed installation position for the oil-conducting cotton 140. It is understandable that the cross-sectional shape of the oil-conducting cotton installation tube 150 can be a common shape such as a circle or a square, as long as the cross-sectional shape of the oil-conducting cotton installation tube 150 can be adapted to the cross-sectional shape of the oil-conducting cotton 140. The present disclosure does not limit the cross-sectional shapes of the oil-conducting cotton installation tube 150 and the oil-conducting cotton 140.
[0036] In some embodiments, since the oil-conducting cotton 140 is made of a material that can be compressed to a certain extent, the diameter of the oil-conducting cotton 140 can be slightly larger than the inner diameter of the oil-conducting cotton mounting tube 150 (taking the example that both are circular), so that the oil-conducting cotton 140 needs to be slightly compressed before it can be installed in the oil-conducting cotton mounting tube 150, which can prevent the oil-conducting cotton 140 from falling off from the oil-conducting cotton mounting tube 150 to a certain extent.
[0037] As the electronic cigarette 100 is continuously used, the oil in the oil storage chamber 110 is gradually consumed, and air will enter the oil storage chamber 110, so that the oil can flow out smoothly. In order to prevent the dense porous structure of the oil-conducting cotton 140 from hindering air from entering the oil storage chamber 110, a certain gap is set between the oil-conducting cotton 140 and the inner wall surface of the oil-conducting cotton mounting tube 150. The gap can serve as a through hole for gas circulation, which is conducive to the oil flowing out of the oil storage chamber 110 at a roughly stable rate.
[0038] Therefore, there is a through hole for gas circulation between the oil-conducting cotton 140 and the oil-conducting cotton mounting tube 150, which is conducive to the oil flowing out of the oil storage chamber 110 at a roughly stable rate, and to a certain extent helps to alleviate the possible oil leakage problem.
[0039] Figure 3 2 is a cross-sectional view of an electronic cigarette according to another embodiment of the present disclosure. Figure 3 As shown, the bottom of the oil storage chamber 110 has an oil hole 111, and the oil hole 111 is sealed by a film. In addition, the oil guide cotton installation tube 150 also includes an oil passage 151, which is configured to pierce the film and extend into the oil storage chamber 110, so that the oil guide cotton 140 is in contact with the smoke oil inside the oil storage chamber 110.
[0040] exist Figure 3 In the illustrated embodiment, the oil storage chamber 110 may be a structure that can be separately disassembled from the electronic cigarette 100, so as to facilitate replacement of the oil storage chamber 110. An oil hole 111 that is pre-sealed with a film may be provided at the bottom of the oil storage chamber 110. When the oil storage chamber 110 is installed to the electronic cigarette 100, the oil passage 151 provided on the oil guide cotton installation tube 150 can pierce the film and extend into the oil storage chamber 110, so that the oil guide cotton 140 and the smoke oil inside the oil storage chamber 110 contact each other, thereby realizing the oil supply from the oil storage chamber 110 to the atomization core 120.
[0041] Therefore, by providing an oil hole 111 sealed with a film in advance at the bottom of the oil storage chamber 110, and adding an oil passage 151 capable of piercing the film at the oil guide cotton mounting tube 150, the oil storage chamber 110 becomes a structure that can be separately disassembled from the electronic cigarette 100, which is further conducive to the replacement of the oil storage chamber 110 and reduces the cost of using the electronic cigarette 100 for the user to a certain extent.
[0042] According to some embodiments of the present disclosure, the second end of the oil-conducting cotton 140 is in contact with the oil-storing cotton 130 in the vertical direction. Thus, such an arrangement reduces the distance that the oil-conducting cotton 140 and the oil-storing cotton 130 may occupy in the horizontal direction, and can reduce the width and / or diameter of the electronic cigarette 100, which is conducive to the miniaturization of the electronic cigarette 100.
[0043] In some embodiments, the second end of the oil-conducting cotton 140 and the oil-storing cotton 130 are in contact with each other in the vertical direction, and the second end of the oil-conducting cotton 140 is located above the oil-storing cotton 130 in the vertical direction. In such an arrangement, gravity also acts on the oil inside the oil-conducting cotton 140, helping the oil to flow from the oil-conducting cotton 140 to the oil-storing cotton 130, which is beneficial to the smooth flow of the oil to the atomizer core 120 to a certain extent.
[0044] According to some embodiments of the present disclosure, the second end of the oil-conducting cotton 140 is in contact with the oil-storing cotton 130 in the horizontal direction. Thus, such an arrangement can provide a better buffering effect to a certain extent, and prevent excessive oil supply to the atomizing core 120.
[0045] According to some embodiments of the present disclosure, the inner wall surface of the oil-conducting cotton mounting tube 150 includes a limit ring 152, which is located near the end of the oil storage chamber 110 in the length direction of the oil-conducting cotton mounting tube 150, and restricts the position of the first end of the oil-conducting cotton 140, thereby facilitating the second end of the oil-conducting cotton 140 to form an interference fit with the oil storage cotton 130.
[0046] Therefore, the limiting ring 152 can, to a certain extent, keep the oil-conducting cotton 140 and the oil-storing cotton 130 in a state of mutual squeezing, which is beneficial for the smoke oil in the oil-conducting cotton 140 to flow to the oil-storing cotton 130, so that the smoke oil can smoothly flow through the junction of the oil-conducting cotton 140 and the oil-storing cotton 130, thereby avoiding the occurrence of poor oil supply to a certain extent.
[0047] Figure 6 2 is a cross-sectional view of an oil-conducting cotton installation tube according to some embodiments of the present disclosure. Figure 6 As shown, the through hole is a groove formed on the inner wall of the oil-conducting cotton installation tube 150 by the tube wall of the oil-conducting cotton installation tube 150 protruding outward. Therefore, using the groove formed by the tube wall of the hard oil-conducting cotton installation tube 150 protruding outward as the through hole is conducive to providing a gap with a stable cross-sectional area for gas circulation, which is conducive to the oil flowing out of the oil storage chamber 110 at a roughly stable rate.
[0048] Figure 7 sectional views of oil-conducting cotton installation tubes according to other embodiments of the present disclosure. Figure 7 As shown, the through hole is a groove formed by the oil-conducting cotton 140 being recessed inwardly so as to be in contact with the inner wall surface of the oil-conducting cotton mounting tube 150. Since the material of the oil-conducting cotton 140 is easy to process, providing the through hole for gas circulation on the oil-conducting cotton 140 can reduce the time and cost required for processing.
[0049] According to some embodiments of the present disclosure, the electronic cigarette 100 further includes an air inlet 161 , which is connected to the atomizer core 120 through an air inlet channel 162 , and at least a portion of the air inlet channel 162 extends in a vertical direction.
[0050] 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 161-air inlet channel 162-atomizer core 120-smoking port", and smoke will not appear in the air inlet channel 162 or even the air inlet 161, so there will be no condensation of smoke oil 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 120 to the air inlet channel 162 or even the air inlet 161, and the temperature at the air inlet channel 162 or the air inlet 161 is relatively low, which may further form condensation of smoke oil and cause oil leakage.
[0051] Therefore, by setting at least a portion of the air inlet channel 162 to extend in the vertical direction, under the action of gravity, the air inlet channel 162 extending in the vertical direction hinders the possible condensed smoke oil from continuing to move toward the air inlet 161 to a certain extent, which is helpful to prevent the problem of smoke oil leakage at the air inlet 161.
[0052] According to some embodiments of the present disclosure, the position of the air inlet 161 in the vertical direction is not lower than the position of the top of the atomizer core 120, and the air inlet 161 is connected to the bottom of the atomizer core 120 through the air inlet channel 162. As a result, the length of the air inlet channel 162 extending in the vertical direction is further increased, which to a certain extent hinders the possible condensed smoke oil from continuing to move toward the air inlet 161, which is conducive to preventing the problem of smoke oil leakage at the air inlet 161.
[0053] According to some embodiments of the present disclosure, the electronic cigarette 100 further includes a seat body 170, which is used to mount the atomizer core 120 and define the bottom surface of the air inlet channel 162, and a first oil-absorbing cotton 171 is disposed on the seat body 170. Therefore, the first oil-absorbing cotton 171 disposed on the seat body 170 can absorb the condensed smoke oil generated at the air inlet channel 162 to a certain extent, which is conducive to preventing the smoke oil from leaking from the air inlet channel 162.
[0054] like Figure 8 As shown, the electronic cigarette 100 further includes a second oil-absorbing cotton 180, which is wrapped around the outer side of the atomizing core 120 and in contact with the oil-storing cotton 130, and the second oil-absorbing cotton 180 and the oil-storing cotton 130 abut against each other. Preferably, the second oil-absorbing cotton 180 and the oil-storing cotton 130 can be set to an interference fit to achieve full contact of the abutting surface. Therefore, by adding the second oil-absorbing cotton 180 on the periphery of the atomizing core 120, it is helpful to prevent excessive oil conduction.
[0055] According to some embodiments of the present disclosure, the electronic cigarette 100 further includes a suction port 191, which is connected to the atomizer core 120 through an exhaust channel 192 extending in a vertical direction. Therefore, arranging the suction port 191 in a vertical direction is conducive to preventing the incompletely atomized smoke oil or condensed smoke oil in the exhaust from being discharged from the suction port 191.
[0056] According to some embodiments of the present disclosure, a third oil-absorbing cotton 193 is disposed on the side of the exhaust channel 192. Thus, the third oil-absorbing cotton 193 can further absorb the incompletely atomized smoke oil or condensed smoke oil generated inside the exhaust channel 192.
[0057] According to some embodiments of the present disclosure, the number of the oil-conducting cotton installation tube 150 and the oil-passing tube 151 is two, and in some other embodiments, the number of the oil-conducting cotton installation tube 150 and the oil-passing tube 151 is set as required. It is understandable that the present application does not limit the number of the oil-conducting cotton installation tube 150 and the oil-passing tube 151.
[0058] 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. In particular, as long as there is no structural conflict, the various technical features mentioned in the various embodiments can be combined in any way.
