Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of electronic cigarettes, and in particular, to an electronic cigarette atomizer and an electronic cigarette. Background Art

[0002] During the use of tobacco products (such as cigarettes, cigars, etc.), tobacco is burned to generate tobacco smoke. People have tried to replace these tobacco-burning products by manufacturing products that release compounds without burning.

[0003] Examples of such products are heating devices that release compounds by heating rather than burning materials. For example, the material can be tobacco or other non-tobacco products, which may or may not contain nicotine. As another example, there are aerosol-providing articles, such as so-called electronic cigarette devices. These devices usually contain a liquid that is heated to vaporize it, thereby generating an inhalable vapor or aerosol. The liquid can contain nicotine and / or flavorants and / or aerosol-forming substances. As a known electronic cigarette, Patent No. 201810150690.7 uses a block-shaped porous ceramic body with grooves on the upper surface as a medium for liquid matrix transfer, and a heating element is provided on the lower surface opposite to the grooves to heat the liquid matrix absorbed by the porous ceramic body, thereby generating an aerosol for inhalation. The above-known electronic cigarette device needs to use a rigid support element to accommodate and hold the porous ceramic body and then wrap it with a silica gel sealing element for overall assembly in the electronic cigarette device. There are relatively many components and it is not convenient for assembly. Summary of the Invention

[0053] For the convenience of understanding the present application, the present application will be described in more detail below in conjunction with the accompanying drawings and specific implementation manners.

[0054] The present application proposes an electronic cigarette, which can be seen in Figure 1 shown, including an atomizer 100 that stores a liquid matrix and vaporizes it to generate an aerosol, and a power supply device 200 that powers the atomizer 100.

[0055] In an alternative implementation, for example Figure 1 shown, the power supply device 200 includes a receiving cavity 270 provided at one end along the length direction for receiving and accommodating at least a part 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 part of the atomizer 100 is received and accommodated in the power supply device 200, so as to power the atomizer 100.

[0056] According to Figure 1In the preferred embodiment shown, a second electrical contact 72 is provided at an end of the atomizer 100 opposite to the power supply device 200 in the longitudinal direction. Thus, when at least a part of the atomizer 100 is received in the receiving cavity 270, the second electrical contact 72 forms an electrical connection by contacting and abutting against the first electrical contact 230.

[0057] A seal 260 is provided in the power supply device 200, and at least a part of the internal space of the power supply device 200 is separated by the seal 260 to form the above-mentioned receiving cavity 270. Figure 1 In the preferred embodiment shown, the seal 260 is configured to extend in the cross-sectional direction of the power supply device 200 and is made of a flexible material, thereby preventing the liquid matrix seeping from the atomizer 100 into the receiving cavity 270 from flowing to components such as the controller 220 and the sensor 25 inside the power supply device 200.

[0058] In Figure 1 In the preferred embodiment shown, the power supply device 200 further includes a battery cell 210 near the other end opposite to the receiving cavity 270 in the longitudinal direction for power supply; and a controller 220 disposed between the battery cell 210 and the receiving cavity. The controller 220 is operable to direct current between the battery cell 210 and the first electrical contact 230.

[0059] In use, the power supply device 200 includes a sensor 250 for sensing the suction air flow generated when sucking through the mouthpiece cover 20 of the atomizer 100. Thus, the controller 220 controls the battery cell 210 to output current to the atomizer 100 according to the detection signal of the sensor 250.

[0060] Further, in Figure 1 In 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 connecting to an external charging device.

[0061] Figure 2 Shows Figure 1 A schematic structural diagram of an embodiment of the atomizer 100, including:

[0062] A main housing 10; according to Figure 2 As shown, the main housing 10 is generally in the shape of a flat square column, and of course, it is hollow inside for storing and atomizing necessary functional devices for the liquid matrix; in Figure 1 In it, a mouthpiece cover 20 for sucking is provided at the upper end in the longitudinal direction, and an end cap 30 for closing the lower end of the main housing 10 is provided at the lower end.

[0063] According to Figure 2, The mouthpiece cover 20 is sleeved on the upper end of the main housing 10 and wraps at least part of the outer surface of the main housing 10, such that a part of the main housing 10 is covered and at least another part is exposed by the mouthpiece cover 20. Further, when the main housing 10 is made of a transparent material, structures such as the air flow channel and the liquid storage cavity inside the main housing 10 are at least partially visible, which is convenient for users to observe the consumption of the liquid matrix and the amount of aerosol during the suction process.

[0064] Meanwhile, at least a part of the outer contour dimension of the mouthpiece cover 20 in the direction away from the main housing 10 gradually decreases, thereby forming a mouthpiece A that is convenient for users to suck.

[0065] Further in Figure 2 and Figure 3 In the preferred embodiment shown, the mouthpiece cover 20 can be detached or removed from the upper end of the main housing 10. After the mouthpiece cover 20 is removed, a channel for injecting liquid into the liquid storage cavity 13 in the main housing 10 is exposed, which is convenient for users to perform the liquid injection operation. In Figure 3 In an optional detachable connection structure between the mouthpiece cover 20 and the main housing 10 shown, a snap fit is used. Specifically, a first convex 11 is provided on the outer side wall of the main housing 10 in the width direction, and a first slot 21 that cooperates with the first convex 11 is provided on the inner side wall of the mouthpiece cover 20 in the width direction.

[0066] Further according to Figure 2 and Figure 3 , after removal, the upper end of the main housing 10 is sealed by a sealing cover 60. The sealing cover 60 is preferably made of a flexible sealing material such as silica gel; at least two first through holes 61 are provided on the sealing cover 60, and these two first through holes 61 communicate with the liquid storage cavity 13 for storing the liquid matrix in the main housing 10; any one of these two first through holes 61 can be used for injecting liquid into the liquid storage cavity 13 of the main housing 10, and the other is used for the air in the main housing 10 to escape during the liquid injection operation, so as to keep the normal pressure in the liquid storage cavity 13 during the liquid injection operation and avoid leakage of the liquid matrix caused by high pressure.

[0067] According to Figure 4 shown, two plug rods 22 corresponding to the first through holes 61 are provided inside the mouthpiece cover 20. During assembly, the plug rods 22 extend into the first through holes 61 to block and seal the first through holes 61, preventing the liquid matrix from leaking out of the first through holes 61 during use.

[0068] Further in Figure 3 and Figure 4In the optional implementation shown, a second through hole 62 is further provided on the sealing cover 60, and a first air flow channel 23 corresponding to the second through hole 62 is provided in the nozzle cover 20. The first air flow channel 23 is located at the port at the upper end of the nozzle cover 20 to form a nozzle opening A, and the port at the lower end is opposite to the second through hole 62, so that after assembly, the aerosol in the main shell 10 is output to the nozzle opening A through the second through hole 62 and the first air flow channel 23.

[0069] See also Figures 5 to 7 As shown, the space inside the main housing 10 is divided into two parallel parts, namely, the liquid storage chamber 13 for storing the liquid matrix and the second air flow channel 14 for outputting the generated aerosol to the second through hole 62. The space of the above liquid storage chamber 13 and the second air flow channel 14 is separated and formed by a partition wall 12 arranged in the main housing 10 and extending in the length direction, and then extending in the length direction. Figures 5 to 7 As shown, the liquid storage chamber 13 and the second air flow channel 14 are defined by the inner wall of the main housing 10 , the inner bottom wall of the end cover 30 , and the wall of the partition wall 12 .

[0070] See also Figure 7 As shown in the figure, the extension dimension of the second air flow channel 14 along the width direction is smaller than the width of the main shell 10, and the two ends of the second air flow channel 14 along the width direction are not connected to the inner wall of the main shell 10, so that the formed liquid storage chamber 13 is roughly C-shaped along the cross-sectional direction and semi-surrounds the second air flow channel 14.

[0071] Based on the realization of atomization, an atomization assembly 40 is arranged near the lower end of the main housing 10. Figure 5 and Figure 6 In the preferred embodiment shown, the atomizing assembly 40 includes a porous body 41 that is generally sheet-shaped or plate-shaped and extends along the length direction of the main housing 10. The porous body 41 is located between the liquid storage chamber 13 and the second air flow channel 14 along the thickness direction of the main housing 10. In the embodiment, the surface of the porous body 41 opposite to the liquid storage chamber 13 is configured to contact the liquid matrix in the liquid storage chamber 13, and is further configured as a liquid absorption surface 410 that absorbs the liquid matrix through capillary infiltration; the surface of the porous body 41 opposite to the second air flow channel 14 is configured to communicate with the second air flow channel 14, and is configured as an atomizing surface 420; and a heating element 42 is provided on the atomizing surface 420, which is used to heat and vaporize at least a portion of the liquid matrix in the porous body 41 to generate an aerosol, which is then released or escaped from the atomizing surface 420 to the second air flow channel 14. In the embodiment shown in the figure, the liquid absorption surface 410 and / or the atomizing surface 420 are flat planes. In other optional implementations, the liquid absorption surface 410 and / or the atomization surface 420 may also be a curved arc surface, or a concave surface with a recessed groove.

[0072] In some embodiments, the porous body 41 can be made of a hard or rigid capillary structure such as porous ceramics, porous glass ceramics, or porous glass. In some embodiments, the heating element 42 can be made of materials such as stainless steel, nickel-chromium alloy, iron-chromium-aluminum alloy, or titanium metal.

[0073] Preferably, the heating element 42 is formed by mixing a raw material powder with conductivity and a printing aid into a slurry, printing, depositing, or spraying it on the atomization surface 420 along a certain track shape, and then sintering and curing it, so that all or most of it is tightly bonded to the atomization surface 420, achieving effects such as high atomization efficiency, less heat loss, prevention of dry burning, or greatly reducing dry burning. Or in other embodiments, a patterned sheet material can be etched or cut and then bonded to the atomization surface 420.

[0074] In some alternative embodiments, the heating element 42 is a patterned conductive track. For example, the heating element 42 is a shape structure such as a meandering, winding, net-shaped, or spiral shape bonded to the atomization surface 420. For example, in Figure 5 and Figure 8 the illustrated embodiment, the heating element 42 is a meandering shape extending along the width direction.

[0075] Further, in Figure 2 and Figure 8 the preferred embodiment shown, the heating element 42 includes electrical connection portions 421 located at both ends of the conductive track. The electrical connection portions 421 are used to supply power to the heating element 42 after being connected to the positive and negative electrodes of the battery cell 210. In an alternative embodiment, the electrical connection portions 421 can be made of materials with better conductivity and lower resistivity, such as silver, copper, gold, or alloys containing them.

[0076] According to Figure 2 、 Figure 5 、 Figure 6 and Figure 9 the preferred embodiment shown, the end cap 30 at the lower end of the main housing 10 is used to seal and support the atomization assembly 40. Specifically, the end cap 30 has a clamping wall 31 extending towards the main housing 10 along the length direction, and the two clamping walls 31 respectively surround and clamp the main housing 10 along the thickness direction. Of course, in terms of the connection method, second card slots 15 are provided on the two outer side walls of the main housing 10 along the thickness direction, and second card protrusions 311 that cooperate with the second card slots 15 for fixation are provided on the clamping wall 31.

[0077] Further, in the structure of the end cap 30, an air inlet hole 32 is provided on the bottom surface of the end cap 30 facing away from the main housing 10. It is in air flow communication with the second air flow channel 14 and is used to supply external air into the main housing 10 during the suction process.

[0078] On the bottom surface of the end cap 30, there is also provided an electrical contact mounting groove 33 for at least a part of the conductive connector 70 to penetrate through and then be flatly attached along the thickness direction. At least a part of the conductive connector 70 forms a second electrical contact 72 within the electrical contact mounting groove 33.

[0079] See Figure 2 and Figure 5 , for facilitating the connection between the atomizer 100 and the power supply device 200, at the lower end of the main housing 10, there are extension parts 16 on both sides of the end cap 30 along the width direction. After installation, the end cap 30 is located within the holding space formed between the extension parts 16. Mounting holes 161 are provided on the extension parts 16, and magnetic elements 17 are installed within the mounting holes 161 for forming a magnetic connection with the power supply device 200 and then stably holding when received within the receiving cavity 270 of the power supply device 200. And the magnetic elements 17 can assist the user. When the user inserts the atomizer 100 into the receiving cavity 270, the magnetic attraction gradually increases, and a clicking sound is generated during combination, indicating the operation result of smooth combination.

[0080] Further see Figure 5 and Figure 8 , in the conductive structure for supplying power to both ends of the heating element 42, the conductive connector 70 is configured to be generally L-shaped. At least a part of the upper end of the conductive connector 70 forms an elastic first conductive connection part 71 after being bent. After assembly, the first conductive connection part 71 abuts against the electrical connection part 421 or the atomizing surface 420. There is a certain distance between the main body part of the conductive connector 70 and the atomizing surface 420. The main part of the conductive connector 70 extends along the length direction, and the second conductive connection part 72 near the lower end is configured to be bent along the thickness direction to form the second electrical contact 72. According to the preferred embodiment shown in the figure, when the second electrical contact 72 is held within the electrical contact mounting groove 33, it is substantially flush with the bottom surface of the end cap 30. In the preferred embodiment shown in the figure, in order to improve the stability of abutting or disengaging with the electrical connection part 421 of the heating element 42, the conductive connector 70 itself generates an elastic force along the thickness direction of the atomizer 100 with respect to the electrical connection part 421 through bending of sheet or strip metal, etc., and then elastically abuts.

[0081] In Figure 7 and Figure 9 the preferred embodiment shown, a tab 34 extending along the width direction is provided within the end cap 30. The tab 34 divides the interior of the end cap 30 into a first cavity 310 and a second cavity 320 arranged in parallel along the thickness direction. On the corresponding mating structure, a holding groove 18 is provided near the lower end inside the main housing 10. Further in Figure 7In the preferred embodiment shown, the holding groove 18 may be formed by a partial structure at the lower end of the partition wall 12 that separates or defines the liquid storage chamber 13 and the second air flow channel 14.

[0082] The holding groove 18 is in the shape of an open lower end, and together with the first concave cavity 310 of the end cap 30, forms a holding space for accommodating and holding the porous body 41.

[0083] Further, in order to assist in sealing the liquid storage chamber 13 and the atomization assembly 40, a sealing element 80 made of a flexible material such as silicone is provided between the main housing 10 and the end cap 30. The sealing element 80 generally includes two parts:

[0084] That is Figure 8 a vertical portion 81 extending along the length direction of the main housing 10, and a horizontal portion 82 perpendicular to the vertical portion 81; in use, the vertical portion 81 is in a circular shape and thus wraps around the porous body 41 in the circumferential direction of the porous body 41.

[0085] Specifically in terms of structure, the vertical portion 81 has a holding space penetrating in the thickness direction, so that in practice the porous body 41 is accommodated and held in this holding space and thus wrapped by the vertical portion 81.

[0086] Furthermore, for the sealing element 80 having the above structure, the vertical portion 81 forms a holding space by penetrating in the thickness direction, so that after wrapping the porous body 41, it is an open or unclosed structure in the thickness direction, thereby ensuring that the liquid absorption surfaces 410 and the atomization surfaces 420 on both sides of the porous body 41 are exposed, enabling the liquid absorption surface 410 of the porous body 41 to maintain liquid communication with the liquid storage chamber 13 and the atomization surface 420 to maintain air flow communication with the second air flow channel 14.

[0087] In use, the above vertical portion 81 is formed between the holding space surrounded by the holding groove 18 and the first concave cavity 310 and the porous body 41, and is used to seal the gap between the holding groove 18 and / or the first concave cavity 310 and the porous body 31.

[0088] The horizontal portion 82 faces the liquid storage chamber 13 during assembly and is thus used to seal the lower end of the liquid storage chamber 13. At the same time, the horizontal portion 82 also faces the second concave cavity 320 of the end cap 30 and is accommodated and held by the second concave cavity 320 of the end cap 30.

[0089] Furthermore, to facilitate the assembly of the end cap 30 and the sealing element 80, a positioning groove 83 is provided on the sealing element 80 that is opposite to and adapted to the tab 34 of the end cap 30. During the assembly process, the tab 34 is aligned with the positioning groove 83 and extends along the length direction, which not only facilitates the positioning of the installation of the sealing element 80 but also provides rigid support for various parts of the sealing element 80.

[0090] According to Figure 8 the preferred embodiment shown, the vertical portion 81 of the sealing element 80 is arranged offset from the center of the sealing element 80, making it easier to hold the liquid matrix in the liquid storage chamber 13.

[0091] In Figure 7 the preferred embodiment shown, the structure of the partition wall 12 includes:

[0092] a separating portion 121 extending longitudinally, mainly used to separate the internal space of the main housing 10 to form the liquid storage chamber 13 and the second air flow channel 14.

[0093] a holding portion 122 extending in the width direction, which is mainly used to form the above-mentioned holding groove 18, and is used to cooperate with the end cap 30 to form a holding space for accommodating and holding the atomization assembly 40. Among them, the vertical portion 81 of the sealing element 80 is mainly located between the holding portion 122 and the atomization assembly 40.

[0094] at least one convex plate 123 extending from the separating portion 121 in the thickness direction into the liquid storage chamber 13. The convex plate 123 abuts or is connected to the holding portion 122 that forms the holding groove 18, and thus can be used as a reinforcing structure to enhance the strength, so that the plastic holding portion 122 will not bend or deform outward in the case of being closely abutted against the sealing element 80, preventing the reduction of the tightness between the sealing element 80 and affecting the sealing effect.

[0095] According to Figure 7 the preferred embodiment shown, the holding portion 122 is offset relative to the separating portion 121.

[0096] Furthermore, according to Figure 6 shown, the air inlet hole 32 of the end cap 30 is inclined, and the air outlet port of the air inlet hole 32 faces the atomization surface 420 or the heating element 42, so that the incoming air can take away the aerosol escaping from the atomization surface 420 as much as possible.

[0097] Further referring to Figure 5 and Figure 9 , the cross-section of the air inlet hole 32 is in the shape of an elongated strip extending in the width direction.

[0098] For the electronic cigarette of another preferred embodiment proposed in this application, see Figure 10As shown, the atomizer 100a is removably received in the receiving cavity 270a of the power supply device 200a. And when the atomizer 100a is received in the receiving cavity 270a, the first electrical contact 230a of the power supply device 200a is electrically connected to the second electrical contact 72a of the atomizer 100a, thereby enabling the power supply device 200a to supply power to the atomizer 100a.

[0099] In Figure 10 In the preferred embodiment shown, the atomizer 100a further includes a first magnetic attraction element 171a and a second magnetic attraction element 172a; the power supply device 200a is provided with a third magnetic attraction element 281a and a fourth magnetic attraction element 282a. According to Figure 10 As shown, when the atomizer 100a is received in the receiving cavity 270a of the power supply device 200a, the first magnetic attraction element 171a forms a magnetic attraction with the third magnetic attraction element 281a, and the second magnetic attraction element 172a forms a magnetic attraction with the fourth magnetic attraction element 282a, thereby enabling the atomizer 100a to be stably received in the receiving cavity 270a.

[0100] Further in Figure 10 In the embodiment shown, the first magnetic attraction element 171a and the fourth magnetic attraction element 282a are made of soft magnetic materials, such as iron, cobalt, nickel, etc.

[0101] The second magnetic attraction element 172a and the third magnetic attraction element 281a are made of permanent magnetic materials, such as common magnets, neodymium iron boron, etc. And in the setting, the second magnetic attraction element 172a and the third magnetic attraction element 281a have opposite magnetic pole directions. For example, Figure 10 in the second magnetic attraction element 172a, the upper end is the N pole and the lower end is the S pole, and in the third magnetic attraction element 281a, the upper end is the S pole and the lower end is the N pole. Then, during use, it is beneficial that the atomizer 100a can only be received in the receiving cavity 270a in a specific direction shown. And when the atomizer 100a rotates 180 degrees to the opposite state as Figure 10 shown, the second magnetic attraction element 172a and the third magnetic attraction element 281a repel each other. Figure 10 shown.
