Description

Technical Field

[0001] This application relates to the field of electronic atomization technology, and in particular to an electronic cigarette. Background Technology

[0002] In existing technology, electronic cigarettes typically include an e-liquid reservoir and an atomizing component for vaporizing the e-liquid. Normally, the reservoir and atomizing component are isolated, and the e-liquid in the reservoir flows to the atomizing component only when the user needs to use it. However, the commonly used isolation component consists of multiple separate rubber rings. During the assembly of an electronic cigarette, these rubber rings are prone to shifting, resulting in a decrease in the isolation effect. Summary of the Invention

[0003] This application provides an electronic cigarette, which includes:

[0004] Upper shell;

[0005] The chimney is installed inside the upper housing. Both ends of the chimney abut against the inner sidewall of the upper housing, and an oil storage cavity is formed between the chimney and the upper housing. The sidewall of the chimney forms a first through hole.

[0006] A piston, disposed inside a smoke extraction tube, includes an integrally injection-molded abutment portion and a main body portion. The side wall of the main body portion forms at least one second through hole. The piston abuts against the inner side wall of the smoke extraction tube through the abutment portion to isolate the first through hole from the at least one second through hole.

[0007] The atomizing device is located inside the main body at one end.

[0008] The beneficial effects of this application are as follows: Unlike existing technologies, this application uses an integrally injection-molded piston inside the cigarette holder. The piston's contact portion abuts against the inner wall of the cigarette holder, effectively isolating the e-liquid stored in the oil reservoir from the atomizing device—the function of the rubber ring in the prior art. Furthermore, the integral injection-molded structure of the piston allows the contact portion to form a single unit with the main body, reducing piston displacement during electronic cigarette assembly and further improving the isolation effect.

[0029] To enable those skilled in the art to better understand the technical solutions of this application, the electronic cigarette provided by this application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It is understood that the described embodiments are merely some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0030] The terms "first," "second," etc., used in this application are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or apparatuses.

[0031] This application provides an electronic cigarette 1 to address the issue of rubber ring misalignment during electronic cigarette assembly, which affects the isolation between e-liquid and the atomizing device, and improves the preservation of e-liquid. Please refer to [link / reference]. Figures 1-3 , Figure 1 This is a schematic diagram of the structure of an embodiment of the electronic cigarette of this application. Figure 2 yes Figure 1 A schematic diagram of the first cross-sectional structure of the electronic cigarette in the I-I direction. Figure 3 yes Figure 1 A schematic diagram of the second cross-sectional structure of the electronic cigarette in the I-I direction.

[0032] like Figure 1-3 As shown, the electronic cigarette 1 includes an upper housing 11, a smoke tube 20, a push rod 30, a piston 40, an atomizing device 50, a control device 60, a battery 70, a lower housing 12, an outer shell 13, and a bottom cover 14.

[0033] Specifically, the smoke tube 20 is disposed inside the upper housing 11, with both ends of the smoke tube 20 abutting against the inner sidewall of the upper housing 11, and an oil storage cavity 101 is formed between the smoke tube 20 and the upper housing 11, which is used to store e-liquid.

[0034] One end of the push rod 30 is located outside the chimney 20, and the other end of the push rod 30 extends into the chimney 20. The end of the push rod 30 located outside the chimney 20 is provided with a pressing part (not shown in the figure). The diameter of the pressing part is larger than the diameter of the push rod 30 body, so that the user can push the push rod 30 into the chimney 20 by pressing the pressing part.

[0035] A piston 40 is disposed inside the smoke extraction tube 20, with one end of the piston 40 abutting against a push rod 30. One end of the atomizing device 50 is disposed inside the piston 40. The push rod 30 is used to push the piston 40 to move relative to the smoke extraction tube 20. Figure 2 The first position shown is moved to, as Figure 3 The second position shown allows the e-liquid in the oil storage chamber 101 to flow to the atomizing device 50 through the first through hole 201 on the side wall of the smoke tube 20 and at least one second through hole 401 on the side wall of the piston 40.

[0036] The control device 60 is connected to the atomizing device 50 and is used to provide control signals to the atomizing device 50 to control the atomizing device 50 to atomize the e-liquid to generate smoke for the user to inhale.

[0037] The battery 70 is connected to the atomizing device 50 and the control device 60 respectively, and is used to power the atomizing device 50 and the control device 60.

[0038] One end of the lower housing 12 is fitted over the other end of the atomizing device 50, and the other end of the lower housing 12 is fitted over the other end of the control device 60. The battery 70 is disposed inside the lower housing 12. The bottom cover 14 is snapped into the other end of the control device 60. The outer shell 13 is fitted over the lower housing 12 and is connected to the upper housing 11 and the bottom cover 14.

[0039] When the user pushes the push rod 30 into the smoke chamber 20, causing the piston 40 to move to the second position, the push rod 30 can be pulled out of the smoke chamber 20, allowing the airflow channel inside the electronic cigarette 1 to connect with the outside atmosphere. At this time, the end of the upper shell 11 away from the lower shell 12 forms a mouthpiece (not shown in the figure), through which the user inhales the vapor produced by the electronic cigarette 1.

[0040] Optionally, in this embodiment, the electronic cigarette 1 may further include a condensing cotton 80, which is sleeved on the side of the push rod 30 away from the pressing part and abuts against the inner wall of the smoking tube 20 to fix the condensing cotton 80. The condensing cotton 80 is used to absorb the vapor that has liquefied due to the decrease in gas temperature, that is, to absorb the condensate, and also to absorb the e-liquid that has not been completely atomized.

[0041] Combination Figures 1-3 For further information Figures 4-5 , Figure 4 yes Figure 2 A schematic diagram of the structure of one embodiment of a central chimney. Figure 5 yes Figure 4 A schematic diagram of the cross-sectional structure of the central exhaust pipe along the II-II direction. (See diagram below.) Figures 4-5 As shown, the chimney 20 includes a first cylinder 21, a second cylinder 22, a third cylinder 23, a fourth cylinder 24, a fifth cylinder 25, and a second abutment portion 26 disposed on the outer side wall of the fifth cylinder 25. The chimney 20 abuts against the inner side wall of the upper housing 11 through the second abutment portion 26.

[0042] The first cylinder 21, the second cylinder 22, the third cylinder 23, the fourth cylinder 24, and the fifth cylinder 25 are arranged sequentially, and the outer diameters of the first cylinder 21, the second cylinder 22, the third cylinder 23, the fourth cylinder 24, and the fifth cylinder 25 increase sequentially. Specifically, the inner diameter of the first cylinder 21 is equal to the inner diameter of the second cylinder 22, and smaller than the inner diameter of the third cylinder 23.

[0043] like Figure 2 and Figure 3 As shown, the end of the first cylinder 21 away from the piston 40 is engaged with the end of the upper housing 11 that forms a suction nozzle. The condensing cotton 80 is disposed at the end of the third cylinder 23 near the second cylinder 22 and abuts against the connection between the second cylinder 22 and the third cylinder 23.

[0044] Specifically, in this embodiment, the side wall of the end of the smoke extractor 20 away from the piston 40 is laser-welded to one end of the upper housing 11, as shown below. Figure 3 As shown in area A. The second abutment part 26 is laser welded to the side wall of the upper housing 11, as shown in the figure. Figure 3 As shown in area B. In this embodiment, laser welding is performed at the contact point between the smoke tube 20 and the upper housing 11 to fix the smoke tube 20 and the upper housing 11, thereby improving structural stability and airtightness, and also improving the freshness of the e-liquid in the oil storage chamber 101.

[0045] The inner diameters of the first cylinder 21, the second cylinder 22, and the condenser cotton 80 are equal, so that when the push rod 30 is placed inside the smoke extractor 20, it abuts against the inner walls of the first cylinder 21 and the second cylinder 22.

[0046] The fifth cylindrical body 25 is provided with a plurality of first through holes 201 and a plurality of third through holes 202, wherein the first through holes 201 and the third through holes 202 are spaced apart at both ends of the side wall of the fifth cylindrical body 25 along a direction perpendicular to the diameter of the fifth cylindrical body 25. The first through holes 201 are provided on the side of the fifth cylindrical body 25 closer to the fourth cylindrical body 24, and the third through holes 202 are provided on the other side of the fifth cylindrical body 25 away from the fourth cylindrical body 24.

[0047] Furthermore, the opening size of the first through hole 201 is larger than the opening size of the third through hole 202. When the piston 40 moves to the second position, the smoke tube 20 mainly communicates with the second through hole 401 on the piston 40 through the first through hole 201, and most of the e-liquid flows downward to the atomizing device 50 through the first through hole 201 and the second through hole 401.

[0048] Combination Figure 1-5 For further information Figures 6-8 , Figure 6 yes Figure 1 A schematic diagram of the structure of one embodiment of the piston. Figure 7 yes Figure 6 A schematic diagram of the exploded structure of the piston. Figure 8 yes Figure 6 A top view of the piston. (e.g.) Figures 6-8 As shown, the piston 40 includes an integrally injection-molded abutment portion 42 and a main body portion 41, and at least one second through hole 401 is provided on the main body portion 41.

[0049] In this embodiment, a one-piece injection-molded piston 40 is installed inside the cigarette holder 20. The piston 40 abuts against the inner wall of the cigarette holder 20, thereby isolating the e-liquid from the atomizing device 50. Furthermore, the one-piece injection-molded structure of the piston 40 makes the abutment portion 42 and the main body 41 form an integral structure, which can reduce the displacement of the abutment portion 42 during the assembly of the piston 40 into the electronic cigarette 1, further improving the isolation effect.

[0050] Optionally, in this embodiment, the piston 40 may be a two-color injection molded structure, with the abutment part 42 being a soft rubber part and the main body part 41 being a hard rubber part, wherein the diameter of the abutment part 42 is larger than the diameter of the main body part 41, so that the piston 40 abuts against the inner wall of the chimney 20 through the abutment part 42.

[0051] In contrast to the existing technology that uses multiple separate rubber rings to form an isolation component, in this embodiment, the abutment part 42 is integrally formed with the main body part 41. Specifically, the abutment part 42 of the soft rubber part plays the same role as the rubber ring. The abutment part 42 abuts against the inner wall of the smoke tube 20 so that the piston 40 and the smoke tube 20 are in a sealed state, that is, there is no gap between the piston 40 and the smoke tube 20. E-liquid cannot flow from the gap between the piston 40 and the smoke tube 20 to the atomizing device 50, thereby achieving the effect of keeping the e-liquid fresh.

[0052] Meanwhile, existing technologies use multiple separate rubber rings. During assembly, the rubber rings rub against the sidewalls of other components, generating frictional force, which can easily cause the rubber rings to shift. In this embodiment, the abutment part 42 is integrally formed with the main body part 41. When assembling the piston 40 and the chimney 20, the integrally formed structure ensures that even when the abutment part 42 rubs against the sidewall of the chimney 20 and generates frictional force, the position of the abutment part 42 relative to the main body part 41 remains unchanged.

[0053] Specifically, the main body 41 includes a first main body 411, a second main body 412 and a third main body 413. The diameter of the second main body 412 is larger than the diameter of the first main body 411 and smaller than the diameter of the third main body 413. At least one second through hole 401 is provided on each side of the second main body 412 near the first main body 411 and the third main body 413.

[0054] The first main body 411, the second main body 412 and the third main body 413 are each provided with an annular groove, and are further provided with a connecting groove that connects the annular groove. The abutting part 42 is correspondingly provided in the annular groove and the connecting groove.

[0055] Furthermore, such as Figure 7 and Figure 8 As shown, the inner wall of the end of the first main body 411 away from the second main body 412 is provided with a relatively extending boss 44. For example... Figure 2 As shown, when the piston 40 is in the first position, the end of the push rod 30 near the piston 40 abuts against the boss 44, so that the push rod 30 applies a thrust to the piston 40 through the boss 44, so that the piston 40 moves relative to the chimney 20.

[0056] like Figure 2 and Figure 5As shown, the fourth cylinder 24 also includes an extension 241. When the piston 40 is in the first position, the extension 241 abuts against the connection between the third main body 413 and the second main body 412, isolating the first through hole 201 and the second through hole 401. Furthermore, the abutting part 42 on the third main body 413 abuts against the inner wall of the fifth cylinder 25, dividing the first through hole 201 and the third through hole into two spaces, so that the e-liquid is stored only in the oil storage chamber 101, thereby improving the preservation degree and purity of the e-liquid.

[0057] like Figure 2 and Figure 3 As shown, one end of the atomizing device 50 is disposed within the main body 41 of the piston 40. (Combined) Figures 1-8 For further information Figures 9-10 , Figure 9 yes Figure 1 An exploded view of one embodiment of the atomizing device. Figure 10 yes Figure 9 A schematic diagram of the cross-sectional structure of the atomizing device along the III-III direction. (See diagram below.) Figure 9 and Figure 10 As shown, the atomizing device 50 includes a first support member 51, a filter assembly 52, an atomizing assembly 53, and a second support member 54.

[0058] The first support member 51 and the second support member 54 are used to support and fix the filter assembly 52 and the atomizing assembly 53. The atomizing assembly 53 is used to atomize the e-liquid, and the filter assembly 52 is used to filter the e-liquid and regulate the flow rate of the e-liquid.

[0059] Combination Figures 1-10 For further information Figures 11-12 , Figure 11 yes Figure 10 A schematic diagram of the structure of one embodiment of the first support member. Figure 12 yes Figure 11 A schematic diagram of the cross-sectional structure of the first support member in the IV-IV direction. (See diagram below.) Figure 11 and Figure 12 As shown, the first support member 51 includes a first support portion 511, a second support portion 512, and a connecting portion 513 connecting the first support portion 511 and the second support portion 512. The inner diameter of the first support portion 511 is smaller than the inner diameter of the second support portion 512, and a portion of the first support portion 511 is disposed inside the main body portion 41 of the piston 40.

[0060] Specifically, the side wall of the second support 512 near the piston 40 is laser-welded to the other end of the upper housing 11, as shown below. Figure 3 As shown in region C. The side wall of the second support 512, at the end opposite to the piston 40, is laser-welded to one end of the lower housing 12, as shown. Figure 3As shown in region D. In this embodiment, laser welding is performed on the contact points between the first support member 51 and the upper shell 11 and the lower shell 12 to achieve fixation between the first support member 51 and the upper shell 11 and the lower shell 12, thereby improving structural stability and airtightness.

[0061] Among them, at least two first protrusions 5131 are provided on the side wall of the connecting part 513 near the first support part 511. For example Figure 7 As shown, the piston 40 has a first groove 45 on the side wall near the first support member 51, and the first protrusion 5131 is used to engage with the first groove 45 to fix the piston 40 when the piston 40 is in the second position.

[0062] The connecting part 513 is also provided with an oil leakage hole 5134. When the piston 40 is in the second position, the first through hole 201 connects with the second through hole 401 to form a first oil injection channel, and the e-liquid flows downward through the oil leakage hole 5134. The size of the oil leakage hole 5134 can control the flow rate of the e-liquid.

[0063] A groove 5132 is formed between at least two first protrusions 5131 and the sidewall of the second support portion 512. A fourth through hole 5133 is further formed between two adjacent first protrusions 5131. When the piston 40 is in the second position, the third through hole 202 connects the first through hole 201 and the fourth through hole 5133 to form a second oil injection channel.

[0064] When the e-liquid flow rate is too slow, or when all the e-liquid in the oil storage chamber 101 has flowed downwards, some e-liquid remains in the space formed by the fifth cylinder 25 and the third main body 413. The e-liquid can flow through the first through hole 201 and the third through hole 202 to the groove 5132, and through the fourth through hole 5133 to the oil leakage hole 5134. This embodiment, by setting a second oil injection channel, can reduce the amount of e-liquid remaining between the piston 40 and the smoke tube 20, thereby improving the utilization rate of e-liquid.

[0065] Optionally, in this embodiment, the atomizing device 50 further includes a rubber ring 55 and a fixing member 56. The diameter of the fixing member 56 is larger than the diameter of the rubber ring 55. The fixing member 56 is used to fix the rubber ring 55 to one end of the first support member 51 located in the main body 41 of the piston 40.

[0066] like Figure 11 As shown, a first mounting step 5111 and a second mounting step 5112 are sequentially formed at the end of the first support portion 511 away from the connecting portion 513. Figure 10 As shown, the rubber ring 55 is disposed on the first mounting step 5111, and the fastener 56 is disposed on the second mounting step 5112.

[0067] like Figure 2 and Figure 3 As shown, the first support member 51 abuts against the inner wall of the third cylinder 23 of the smoke tube 20 through a rubber ring 55. The rubber ring 55 is used to fix the first support member 51 and the smoke tube 20, and also to prevent e-liquid from flowing from the gap between the first support member 51 and the smoke tube 20 to the mouthpiece when the user smokes.

[0068] like Figure 2 and Figure 9 As shown, the filter assembly 52 includes a first filter element 521, a second filter element 522, and a filter screen 523. The first filter element 521 is disposed on the side of the connecting portion 513 near the first support portion 511, and the second filter element 522 and the filter screen 523 are disposed on the side of the connecting portion 513 near the second support portion 512. Optionally, in this embodiment, the first filter element 521 and the second filter element 522 are specifically oil-soaked cotton.

[0069] Specifically, the first filter element 521 is sleeved outside the first support portion 511 and abuts against the inner side wall of the third main body portion 413 of the piston 40. When the push rod 30 pushes the piston 40 to move, it drives the first filter element 521 to move, so that the first filter element 521 abuts against the connecting portion 513.

[0070] The e-liquid flows through the first through hole 201 and the second through hole 401 to the first filter element 521, and then permeates through the first filter element 521 to the oil leakage hole 5134.

[0071] A filter screen 523 is disposed between the connecting portion 513 and the second filter element 522, and abuts against both the connecting portion 513 and the second filter element 522. The filter screen 523 has multiple through holes.

[0072] This embodiment controls the flow rate of e-liquid by changing the size, number, and shape of the through holes. Simultaneously, this embodiment incorporates a first filter element 521, a second filter element 522, and a filter screen 523, utilizing three layers of filtration to improve the purity of the e-liquid flowing to the atomizing device 50, thereby increasing the combustion efficiency and utilization rate of the e-liquid.

[0073] like Figure 2 and Figure 9 As shown, the atomizing component 53 is disposed within the second support portion 512, and the second filter element 522 is sleeved outside the atomizing component 53. The atomizing component 53 includes a support sleeve 531, a flow guide 532, and a heating wire (not shown), with the heating wire disposed within the flow guide 532.

[0074] Optionally, in this embodiment, the drainage element 532 can be a non-woven fabric. Specifically, the drainage element 532 can be formed by pressing two layers of non-woven fabric, and the heating wire is further disposed between the two layers of non-woven fabric, specifically disposed between the two layers of non-woven fabric.

[0075] Specifically, the support sleeve 531 includes a main pipe 5311, a mounting groove 5312 formed on the main pipe 5311, and a fifth through hole 5313 provided on the side wall of the main pipe 5311. The mounting groove 5312 is used to install the guide member 532. The main body of the guide member 532 is disposed in the mounting groove 5312, and the extension of the guide member 532 extends to the outside of the mounting groove 5312. The extension and the main pipe 5311 are covered with a second filter 522. The fifth through hole 5313 is used to allow the main body of the guide member 532 to contact the second filter 522. The guide member 532 is used to guide the e-liquid contained in the second filter 522 to the heating wire. The heating wire is used to heat the e-liquid flowing to the guide member 532.

[0076] Combination Figures 1-12 For further information Figure 13-14 , Figure 13 yes Figure 10 A schematic diagram of the structure of one embodiment of the second support member. Figure 14 yes Figure 13 A top view of the second support member. (See attached image.) Figure 13 and Figure 14 As shown, the second support member 54 includes a first step 541 and a second step 542. The diameter of the second step 542 is larger than the diameter of the first step 541.

[0077] The end of the first support member 51 furthest from the piston 40 is fitted over the second support member 54, specifically fitted onto the first step 541 and abutting against the second step 542.
