DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the schemes in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, top, bottom, side...) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0036] It should also be noted that when an element is referred to as being "fixed on" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element.

[0037] Aiming at the technical defects in the related art, this embodiment provides an electronic cigarette. Figure 1 and Figure 2 As shown, the electronic cigarette of this embodiment includes an atomizing component 100 , an oil tank 200 , an oil filling tube 300 , a sealing member 400 , a control button 500 , a second shell 700 and a battery A.

[0038] The atomizing component 100, oil reservoir 200, oil filling tube 300, and battery A are installed within the second housing 700. The atomizing component 100 forms an atomizing chamber 101, within which is located an atomizing core 102 for atomizing the e-liquid and an oil storage sponge 150 that is sleeved onto the atomizing core 102. The oil reservoir 200 is used to hold the e-liquid, while the oil filling tube 300 connects the atomizing chamber 101 with the inner cavity of the oil reservoir 200. Battery A is used to provide power to the atomizing core 102.

[0039] For example, Figure 2 As shown, oil-absorbing cotton 140 is provided between the atomizing component 100 and the oil tank 200 . The oil-absorbing cotton 140 is used to absorb the smoke oil leaked from the atomizing component 100 to protect other components.

[0040] The seal 400 is embedded in the oil filling tube 300. The control button 500 is disposed outside the atomizing component 100 and is in transmission connection with the seal 400. That is, when an external force is applied to the control button 500, the external force can be transmitted to the seal 400 through the control button 500 and the transmission connection structure between the control button 500 and the seal 400.

[0041] Combine Figure 2 and Figure 5 As shown, when the control button 500 is driven by an external force, the sealing member 400 can be pushed into the oil tank 200 , so that the atomizing chamber 101 and the inner cavity of the oil tank 200 are connected to each other, so that the e-liquid in the oil tank 200 flows into the atomizing chamber 101 through the oil filling pipe 300 .

[0042] For example, the transmission connection between the control button 500 and the sealing member 400 can be achieved through a threaded connection structure such as a screw. For example, the screw is threadedly connected to the atomizing member 100, and the control button 500 rotates the screw to push the sealing member 400. In addition, the transmission connection between the control button 500 and the sealing member 400 can also be achieved through gear transmission or other means, but is not limited thereto.

[0043] Compared to related art, the electronic cigarette of this embodiment forms an opening and closing structure between the atomizing component 100 and the oil reservoir 200. Specifically, the oil filling tube 300 forms a communication channel between the atomizing component 100 and the oil reservoir 200, and a sealing member 400 is embedded in the oil filling tube 300. The control button 500 can use external force to push the sealing member 400 in the oil filling tube 300 into the oil reservoir 200. During transportation of the electronic cigarette of this embodiment, the sealing member 400 is embedded in the oil filling tube 300 to prevent the oil in the oil reservoir 200 from flowing into the atomizing component 100. When using the electronic cigarette of this embodiment, external force is applied to the control button 500, thereby pushing the sealing member 400 into the oil reservoir 200, thereby allowing the oil in the oil reservoir 200 to flow into the atomizing component 100.

[0044] Continue to refer to Figure 3 As shown, the atomizing component 100 is further formed with a connecting channel 103, which is connected to the lumen of the oil filling tube 300 through the atomizing chamber 101. The electronic cigarette of this embodiment also includes a push rod 600 that forms a transmission connection between the control button 500 and the sealing member 400. Figure 3 As shown, a portion of the push rod 600 is located in the atomizing chamber 101. One end of the push rod 600 is connected to the control button 500 via the connecting channel 103, and the other end of the push rod 600 is connected to the sealing member 400 via the lumen of the oil filling tube 300. Thus, in this embodiment, the external force applied to the control button 500 is transmitted to the sealing member 400 via the push rod 600.

[0045] In an optional example, one end of the push rod 600 is threadedly connected to the inner wall of the connecting channel 103. When the push rod 600 is rotated by the control button 500, the push rod 600 can be displaced toward the seal 400, thereby pushing the seal 400 into the oil tank 200.

[0046] In another optional example, one end of the push rod 600 is slidably connected to the inner wall of the connecting channel 103, and the control button 500 is rod-shaped, with one end of the control button 500 connected to the push rod 600. When the control button 500 is pressed, at least a portion of the control button 500 is pushed into the connecting channel 103 and pushes the push rod 600 and the sealing member 400, thereby pushing the sealing member 400 into the oil tank 200.

[0047] Furthermore, the atomizing component 100 includes a cover 110 and a first shell 120, and the first shell 120 is formed with a first receiving groove 121. The first shell 120 has a first shell wall forming the bottom of the first receiving groove 121 and a second shell wall forming the wall of the first receiving groove 121. The cover 110 is connected to the second shell wall, and the atomizing chamber 101 is formed by the cover 110 and the first receiving groove 121. The connecting channel 103 is opened in the cover 110, one end of the oil filling pipe 300 is connected to the first shell wall, and the other end of the oil filling pipe 300 is connected to the oil tank 200.

[0048] Among them, combined Figure 3 and Figure 4 As shown, the cover 110 includes a plug-in connector 111 and a top shell 112. A portion of the plug-in connector 111 is plugged into the first receiving groove 121 to close the notch of the first receiving groove 121. The atomization chamber 101 is formed by the plug-in connector 111 and the first receiving groove 121. Of course, depending on the actual design purpose, the plug-in connector 111 can also be fully plugged into the first receiving groove 121.

[0049] The top shell 112 is formed with a second receiving groove 1121, and the top shell 112 has a third shell wall forming the bottom of the second receiving groove 1121 and a fourth shell wall forming the wall of the second receiving groove 1121. Figure 3 As shown, the fourth shell wall is connected to the second shell wall so that the connector 111 is located in the second receiving groove 1121. The third shell wall defines a first through hole 11211, and the connector 111 defines a second through hole 1111 coaxially arranged with the first through hole 11211. The first through hole 11211 and the second through hole 1111 are connected to each other to form a connecting channel 103.

[0050] Furthermore, the cover 110 further includes a mounting member 113, which is located outside the second shell wall and is connected to the portion of the connector 111 located outside the first receiving groove 121. Figure 3As shown, the connection between the fourth shell wall and the second shell wall also positions the mounting member 113 in the second receiving groove 1121 , thereby making the assembly of the electronic cigarette of this embodiment more compact.

[0051] Continue to refer to, Figure 3 As shown, a suction nozzle 800 is provided on the side of the third shell wall facing away from the connector 111 and the mounting member 113. The suction channel of the suction nozzle 800 is connected to the atomizing core 102 in the atomizing chamber 101. A first mounting groove 1131 is formed on the side of the mounting member 113 facing away from the third shell wall. A microphone 900 for triggering the atomizing core 102 is disposed in the first mounting groove 1131.

[0052] The side of the mounting member 113 facing the third shell wall is formed with a negative pressure air channel 1132 communicating with the first mounting groove 1131. Figure 4 As shown, a first negative pressure air groove 1113 is formed on the side of the connector 111 facing the third shell wall, and a second negative pressure air groove 1133 is formed on the side of the mounting member 113 facing the third shell wall, which is connected to the first negative pressure air groove 1113. The inhalation channel of the mouthpiece 800 can be connected to the first negative pressure air groove 1113 via an additional extended air channel or air groove, and the negative pressure air channel 1132 is connected to the second negative pressure air groove 1133. Therefore, when the user sucks on the mouthpiece 800, the air in the negative pressure air channel 1132 can be evacuated, thereby triggering the microphone 900. Since the microphone 900 is arranged relatively close to the atomizer core 102, the assembly of the electronic cigarette of this embodiment is convenient.

[0053] Further, if Figure 4 As shown, to reduce the risk of condensate generated during electronic cigarette smoking contaminating the microphone 900, a condensate groove B is provided at the bottom of the second negative pressure tank 1133. This design allows the condensate to fall into the condensate groove B as it flows into the second negative pressure tank 1133, thereby reducing the possibility of condensate contaminating the microphone 900. Of course, the condensate groove B can also be provided at the bottom of the first negative pressure tank 1113, or at both the bottom of the first negative pressure tank 1113 and the bottom of the second negative pressure tank 1133.

[0054] Further, continue to refer to Figure 4 As shown, a second mounting groove 1112 is further formed on the side of the connector 111 facing the third shell wall. A third through hole 11121 communicating with the atomizing chamber 101 is formed at the bottom of the second mounting groove 1112. A condensing cotton 130 is disposed in the second mounting groove 1112. The condensing cotton 130 has a fourth through hole 131 for communicating with the third through hole 11121 and the air inlet passage of the suction nozzle 800. Thus, the atomizing core 102 in the atomizing chamber 101 is communicated with the air inlet passage of the suction nozzle 800 via the third through hole 11121 and the fourth through hole 131 in sequence.

[0055] Optionally, in order to simplify the assembly process of the electronic cigarette of this embodiment, the first shell wall, the second shell wall, the oil filling pipe 300 and the oil tank 200 may be an integrally formed structure.

[0056] The above description is only part or preferred embodiments of the present invention. Neither the text nor the drawings can limit the scope of protection of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the overall concept of the present invention, or direct / indirect application in other related technical fields are included in the scope of protection of the present invention.
