[0035] In order to facilitate the understanding of the present application, the present application is described in more detail below with reference to the accompanying drawings and specific implementation methods.

[0036] This application proposes an electronic cigarette, which can be found in Figure 1 As shown, the invention comprises an atomizer 100 for storing a liquid matrix and vaporizing the liquid matrix to generate an aerosol, and a power supply device 200 for supplying power to the atomizer 100 .

[0037] In an alternative implementation, such as Figure 1 As shown, the power supply device 200 includes a receiving cavity 270 arranged at one end along the length direction for receiving and accommodating at least a portion of the atomizer 100, and a first electrical contact 230 at least partially exposed on the surface of the receiving cavity 270, which is used to form an electrical connection with the atomizer 100 when at least a portion of the atomizer 100 is received and accommodated in the power supply device 200, thereby supplying power to the atomizer 100.

[0038] according to Figure 1 In the preferred embodiment shown, a second electrical contact 21 is provided on the end of the atomizer 100 opposite to the power supply device 200 along the length direction, and when at least a portion of the atomizer 100 is received in the receiving cavity 270, the second electrical contact 21 contacts and abuts against the first electrical contact 230 to form conductivity.

[0039] A sealing member 260 is provided in the power supply device 200, and the sealing member 260 separates at least a portion of the internal space of the power supply device 200 to form the above-mentioned receiving cavity 270. Figure 1 In the preferred embodiment shown, the seal 260 is configured to extend along the cross-sectional direction of the power supply device 200 and is made of a flexible material, thereby preventing the liquid matrix that seeps from the atomizer 100 into the receiving chamber 270 from flowing to the controller 220, sensor 250 and other components inside the power supply device 200.

[0040] exist Figure 1 In the preferred embodiment shown, the power supply device 200 also includes a battery cell 210 located along the length direction near the other end relative to the receiving cavity 270 for supplying power; and a controller 220 arranged between the battery cell 210 and the receiving cavity, which is operable to guide current between the battery cell 210 and the first electrical contact 230.

[0041] During use, the power supply device 200 includes a sensor 250 for sensing the suction airflow generated when suction is performed through the nozzle cover 20 of the atomizer 100 , and the controller 220 controls the battery cell 210 to output current to the atomizer 100 according to the detection signal of the sensor 250 .

[0042] Further in Figure 1In the preferred embodiment shown, the power supply device 200 is provided with a charging interface 240 at the other end opposite to the receiving cavity 270 for charging the battery cell 210 after being connected to an external charging device.

[0043] Figures 2 to 4 The embodiment shows Figure 1 A schematic structural diagram of an embodiment of the atomizer 100 includes:

[0044] Main housing 10; Figures 2 to 4 As shown, the main shell 10 is roughly in the shape of a flat cylinder, and of course its interior is hollow for storing and atomizing necessary functional components of the liquid matrix; the main shell 10 has a proximal end 110 and a distal end 120 opposite to each other along the length direction; wherein, according to the needs of normal use, the proximal end 110 is configured as an end for the user to inhale the aerosol, and a mouthpiece A for the user to inhale is provided at the proximal end 110; and the distal end 120 is used as the end for combining with the power supply device 200, and the distal end 120 of the main shell 10 is open, and a detachable end cover 20 is installed on it, and the open structure is used to install various necessary functional components into the interior of the main shell 10.

[0045] Further in Figure 2 In the embodiment shown, a second electrical contact 21 for conducting with the first electrical contact 230 of the power supply device 200 is provided on the end cover 20; and a magnetic attraction element 22 that is stably held by the power supply device 200 through magnetic attraction when received in the receiving cavity 270 of the power supply device 200.

[0046] See further Figure 2 As shown, the main housing 10 is provided with a liquid storage chamber 12 for storing liquid matrix; Figure 2 In the cross-sectional schematic diagram shown, a smoke transmission tube 11 extending axially is provided in the main shell 10. The space between the outer wall of the smoke transmission tube 11 and the inner wall of the main shell 10 forms a liquid storage chamber 12 for storing a liquid matrix; the upper end of the smoke transmission tube 11 is connected to the smoking port A, and is further used to output the aerosol generated in the atomizer 100 to the smoking port A for inhalation by the user.

[0047] To further uniformly vaporize the liquid matrix, a wicking element 30 extending along the width of the main housing 10 is disposed within the main housing 10. The wicking element 30 is made of a porous material, capable of absorbing the liquid matrix within the liquid storage chamber 12 through capillary infiltration. In an alternative embodiment, the wicking element 30 may comprise fiber cotton, fiberglass rope, capillary tubes, microporous ceramics, or the like. During use, the wicking element 30 at least partially extends into the liquid storage chamber 12, absorbing the liquid matrix through capillary infiltration.

[0048] The heating element 40 is configured as a tubular shape extending along the width direction of the main housing 10 and is at least partially disposed around the absorbing element 30. In use, the heating element 40 can heat at least a portion of the liquid matrix in the absorbing element 30 to generate an aerosol for inhalation.

[0049] according to Figure 2 In the structure shown, the main housing 10 has an atomizing chamber 291 defined by the support portion 29 extending from the end cap 20 toward the proximal end 110, and the liquid storage chamber 12 at least partially surrounds the atomizing chamber 291. Figure 5 and Figure 7 In the embodiment shown, the support portion 29 has a side wall 29a and a side wall 29b sequentially arranged along the width direction, and an atomization chamber 291 is defined between the side wall 29a and the side wall 29b. Figure 2 In the preferred embodiment shown, the liquid absorption element 30 is mainly accommodated or located in the atomization chamber 291. At the same time, the two ends of the liquid absorption element 30 along the length direction pass through the support part 29 from the atomization chamber 291 to the liquid storage chamber 12, and then absorb the liquid matrix by capillary infiltration.

[0050] Further in Figure 2 and Figure 4 In the preferred embodiment shown, the heating element 40 is positioned within the atomizing chamber 291 so that the aerosol generated by heating can be released into the atomizing chamber 291 .

[0051] Further based on Figures 3 to 6 As shown, the end of the support portion 29 near the proximal end 110 is designed to be open, with an opening 292. During use, the opening 292 of the support portion 29 is covered with a sealing element 50. The sealing element 50 is provided with an insertion hole 51 for inserting the lower end of the smoke transmission tube 11 into the insertion hole 51, thereby establishing airflow communication with the atomization chamber 291. During use, the aerosol generated by the heating element 40 is released into the atomization chamber 291 and then output by the smoke transmission tube 11 to the inhalation port A for inhalation by the user.

[0052] At the same time, the sealing element 50 covers the support portion 29, thereby sealing the gap between the support portion 29 and the inner wall of the main housing 10, thereby preventing the liquid matrix from leaking out or entering the atomization chamber 291. Of course, the outer surfaces of the side walls 29a and 29b of the support portion 29 are exposed, that is, not covered by the sealing element 50, thereby ensuring that the liquid absorption element 30 can penetrate the side walls 29a and 29b and extend into the liquid storage chamber 12 to absorb the liquid matrix.

[0053] further Figure 6In the preferred embodiment shown, a rib 52 is provided on the sealing element 50. Of course, the rib 52 is supported by the supporting portion 29 so that it can be tightly pressed against the inner wall of the main shell 10, which is conducive to improving the sealing effect.

[0054] In another preferred embodiment, the structural design of the air intake of the above atomizer 100 during the suction process is shown in FIG. Figures 3 to 5 Shown, including:

[0055] The end cover 20 is provided with a main air storage chamber 232; and,

[0056] a first air hole 24 for allowing external air to enter the main air storage chamber 232 during suction;

[0057] A second air hole 27 communicating with the main air storage chamber 232 and the atomization chamber 291;

[0058] During use, external air enters the main air storage chamber 232 through the first air hole 24, and then enters the atomization chamber 291 through the second air hole 27 from the main air storage chamber 232, forming Figure 4 The first airflow path is shown by the arrow R1.

[0059] At the same time, two buffer air chambers 231 are provided in the end cover 20 and arranged on both sides of the main air storage chamber 232 along the width direction; of course, the buffer air chamber 231 is in airflow communication with the main air storage chamber 232; and,

[0060] a third air hole 23 for allowing external air to enter the buffer air chamber 231 during suction;

[0061] During use, the external air can also enter the buffer air chamber 231 through the third air hole 23, then enter the main air storage chamber 232 from the buffer air chamber 231, and then enter the atomization chamber 291 from the main air storage chamber 232 through the second air hole 27, forming Figure 4 The second airflow path is shown by the arrow R2.

[0062] In practice, the outside air can be partially Figure 4 The arrow R1 in the middle enters the atomizing chamber 291 directly through the main air storage chamber 232, and can also partially enter the atomizing chamber 291 along the main air storage chamber 232. Figure 4 As shown by the middle arrow R2, the air passes through the buffer air chamber 231 and the main air storage chamber 232 in sequence and then enters the atomization chamber 291.

[0063] The above preferred multi-path air intake structure helps to reduce the leakage of aerosol condensate from the atomization chamber 291, and the buffer air chamber 231 helps to store excess aerosol.

[0064] In a specific structural implementation, the end cover has a partition wall 233 that defines or separates the buffer air chamber 231 and the main air storage chamber 232. The partition wall 233 has a gap, thereby allowing the separated or defined buffer air chamber 231 and the main air storage chamber 232 to be connected in airflow.

[0065] See further Figures 5 to 7 In the preferred embodiment shown, the heating element 40 includes a first tubular portion 41 at a first end along the length direction, a second tubular portion 42 at a second end, and a resistance heating portion 43 between the first tubular portion 41 and the second tubular portion 42 .

[0066] During preparation or assembly, the heating element 40 is prepared by laser cutting or etching a tubular resistive metal substrate to form a desired hollow or notch 431 on the tube wall, and then forming a resistive heating portion 43 with a suitable resistance value in the middle of the tube. Figure 7 The resistance heating portion 43 shown in the figure is obtained by laser cutting by alternately cutting the tubular metal substrate on two opposite sides along the radial direction to form hollows or notches 431.

[0067] In an optional embodiment, the tubular metal substrate used to prepare the heating element 40 may include at least one of nickel, cobalt, zirconium, titanium, nickel alloy, cobalt alloy, zirconium alloy, titanium alloy, nickel-chromium alloy, nickel-iron alloy, iron-chromium alloy, titanium alloy, iron-manganese-aluminum-based alloy or stainless steel.

[0068] In other optional implementations, the hollowing 431 on the resistance heating portion 43 is spiral-shaped, or has a plurality of circular holes, square holes, polygonal holes, or other shapes.

[0069] exist Figure 5 In the preferred embodiment shown, the heating element 40 is formed integrally with the support portion 29 of the end cap 20 by in-mold injection molding; specifically,

[0070] See also Figure 7 As shown, the first tubular portion 41 and the second tubular portion 42 of the heating element 40 are made to penetrate the side wall 29a / 29b of the support portion 29 by injection molding, and the two are formed Figure 5 At the same time, the openings at both ends of the heating element 40 form holes 293 on the side walls 29a / 29b for the liquid guiding element 30 to penetrate and transfer the liquid matrix.

[0071] By integrating the heating element 40 with the end cap 20 in the above manner, the heating element 40 is supported and secured by the support portion 29, with the resistive heating portion 43 positioned within the atomizing chamber 291. Furthermore, after in-mold injection molding, the first and second tubular portions 41, 42 are tightly fitted to the sidewalls 29a / 29b of the support portion 29, preventing leakage of the liquid matrix therebetween. Consequently, during use, there is no need for sealing material between the heating element 40 and the sidewalls 29a / 29b. After assembly, the liquid matrix within the liquid storage chamber 12 can only exit the liquid storage chamber 12 through the openings at both ends of the heating element 40.

[0072] In addition to the above injection molding, the heating element 40 and the support portion 29 can also be made into a tight-fitting whole by similar prefabricated molding methods such as hot pressing and riveting, and no sealing material is needed between them, so that the liquid matrix cannot seep out from between them.

[0073] According to a preferred embodiment, the second air hole 27 is located at the center of the main shell 10 and overlaps with at least a portion of the resistive heating portion 43 along the length direction of the main shell 10, so that the airflow effectively contacts the resistive heating portion 43 during the suction process.

[0074] exist Figure 5 In the preferred embodiment shown, both ends of the assembled heating element 40 are flush with the surface of the side walls 29 a / 29 b of the support portion 29 .

[0075] See further Figure 4 and Figure 7 As shown, the end cap 20 is further provided with a lead hole 26 for allowing a lead wire (not shown in the figure) to pass through; specifically, after the lead wire passes through the lead hole 26, the upper end is welded to the first tubular portion 41 / the second tubular portion 42 of the heating element 40, and the lower end is in conductive contact with the second electrical contact 21 or welded and conductive, etc.; thereby, the power supply device 200 supplies power to the heating element 40.

[0076] In the implementation, the assembly is completed by passing the absorbent element 30 made of soft fiber rope, fiber cotton, etc. from the first end to the second end of the heating element 40; after assembly, the tubular heating element 40 provides support and retention for the absorbent element 30. The shape of the absorbent element 30 after assembly is as follows: Figure 5 and Figure 6As shown in FIG, the first portion 31 contained and retained within the heating element 40 is compressed into a slender cylindrical shape, while the second portion 32 located outside the heating element 40 and exposed to the liquid storage chamber 12 is in a fluffy or expanded shape, which is more conducive to absorbing the liquid matrix. Furthermore, the flexible filling of the wicking element 30 allows for a small gap between the wicking element 30 and the heating element 40. Furthermore, the wicking element 30 has capillary adsorption, thereby substantially preventing leakage of the liquid matrix therebetween.

[0077] Figure 8 A schematic structural diagram of a heating element 40a in another preferred embodiment is shown. The two ends of the tubular heating element 40a are constructed as frustoconical wide-mouth ends 411a / 421a with gradually increasing inner diameters. The wide-mouth shape is beneficial for the operation of passing the liquid-absorbing element 30 through the heating element 40a during assembly.

[0078] Furthermore, in terms of the sealing structure, the end cap 20 and the space within the main housing 10 define a liquid storage chamber 12; the sealing element 50 at least partially covers the end cap 20 and is at least partially located between the joint portion of the end cap 20 and the main housing 10, thereby preventing the liquid matrix from leaking through the gap between the end cap 20 and the main housing 10.

[0079] See also Figure 5 As shown, the sealing element 50 has windows 53 on both sides along the width direction, which are used to expose the outer surfaces of the side walls 29a / 29b. Therefore, the sealing element 50 is not in contact with the heating element 40 and the liquid-conducting element 30, preventing heat from being transferred to the sealing element 50 and causing the flexible silicone or rubber material of the sealing element 50 to become heat-cured and ineffective.

[0080] See also Figure 7 As shown, the end cover 20 is further provided with an annular mounting groove 28 near the distal end 120 , and the sealing ring 25 is accommodated and retained in the mounting groove 28 , further enhancing the sealing effect.

[0081] It should be noted that the specification and drawings of this application provide preferred embodiments of the present application, but are not limited to the embodiments described in this specification. Furthermore, it is possible for a person skilled in the art to make improvements or changes based on the above description, and all such improvements and changes should fall within the scope of protection of the claims attached to this application.
