[0043] Next, the technical solutions of the present disclosure will be described clearly and completely in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present disclosure without creative efforts shall fall within the protection scope of the present disclosure.

[0045] In the description of the present disclosure, it should be noted that unless otherwise clearly specified and limited, when terms such as "installation", "connection", "coupling" are used, they should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements.

[0046] See Figures 1 to 13 As shown, this embodiment provides an electronic cigarette device, including a feeding device 1. The feeding device 1 includes a feeding hopper 11 and a blanking pipe 12. A feeding port is provided on the side wall of the blanking pipe 12. The outlet of the feeding hopper 11 is communicated with the feeding port. A spiral feeding member is arranged in the blanking pipe 12. The spiral feeding member includes a rotating shaft 13 and spiral blades 14. The axis of the rotating shaft 13 is parallel to the axis of the blanking pipe 12. The spiral blades 14 are arranged on the circumferential side wall of the rotating shaft 13. The rotating shaft 13 can rotate around its own axis so that the spiral blades 14 can drive the tobacco material to move to the outlet of the blanking pipe 12.

[0047] For the electronic cigarette device provided in this embodiment, a spiral feeding member is arranged in the blanking pipe 12 of the feeding device 1. When the tobacco material enters the feeding port provided on the side wall of the blanking pipe 12 from the outlet of the feeding hopper 11, it will fall on the spiral blades 14 of the spiral feeding member. Since the rotating shaft 13 of the spiral feeding member can rotate around its own axis, the spiral blades 14 drive the tobacco material to move together, and then convey the tobacco material to the outlet of the blanking pipe 12, reducing the risk of the tobacco material adhering to the inner wall of the blanking pipe, and further reducing the risk of material jamming during the feeding process.

[0048] In one embodiment, see Figure 13As shown, the feeding hopper 11 has a guiding curved surface 111 to enable the tobacco material to enter the feeding port in an inclined direction. This can ensure that when the tobacco material enters the blanking pipe 12, a certain tangential velocity is generated, and then it falls on the surface of the spiral blade 14 along the rotation direction of the spiral blade 14, facilitating the spiral blade 14 to move together with the tobacco material and then conveying the tobacco material to the discharge port of the blanking pipe 12.

[0049] Meanwhile, when the tobacco material enters the blanking pipe 12 at a certain tangential velocity, the risk of easily adhering to the inner wall of the blanking pipe 12 when freely falling only by its own gravity can be effectively reduced.

[0050] Exemplarily, the guiding curved surface 111 can be a partial side surface of an oblique cone, or can include partial side surfaces of two oblique cones with different oblique angles, and the two side surfaces are smoothly transitioned. This can make the tobacco material gather together. At the same time, due to the guiding curved surface of the feeding hopper having a certain slope, the tobacco material above will squeeze the tobacco material below to the side and enter the blanking pipe 12.

[0051] In one embodiment, the gap between the edge of the spiral blade 14 and the inner wall of the blanking pipe 12 is 0.1 - 1 mm. This can effectively reduce the risk of the tobacco material entering the gap between the edge of the spiral blade and the inner wall of the blanking pipe. Even if a small amount of tobacco material adheres to the inner wall of the blanking pipe 12, since the gap between the edge of the spiral blade 14 and the inner wall of the blanking pipe 12 is much smaller than the inner diameter of the tobacco material, the possibility of the spiral blade 14 scraping off the tobacco material adhering to the inner wall of the blanking pipe 12 is increased, thereby reducing the risk of material jamming.

[0052] Exemplarily, the gap between the edge of the spiral blade 14 and the inner wall of the blanking pipe 12 can be, but is not limited to, 0.1 mm, 0.15 mm, 0.2 mm, 0.22 mm, 0.25 mm, 0.27 mm, 0.28 mm, 0.3 mm, 0.32 mm, 0.34 mm, 0.36 mm, 0.38 mm, 0.4 mm, 0.42 mm, 0.44 mm, 0.46 mm, 0.48 mm, 0.5 mm, 0.55 mm, 0.6 mm, 0.65 mm, 0.7 mm, 0.75 mm, 0.8 mm, 0.85 mm, 0.9 mm, 0.95 mm, 0.98 mm or 1 mm.

[0053] In one embodiment, along the axial direction of the rotating shaft 13, the pitch of the spiral blade 14 near the discharge port is smaller than the pitch of the spiral blade 14 far from the discharge port.

[0054] Specifically, the pitch of the spiral blade 14 far from the discharge port is larger, that is to say, the pitch of the spiral blade 14 close to the feed port is larger. This can provide a larger space for the tobacco material, facilitating the entry of the tobacco material from the outlet of the feed hopper 11 into the feed port of the blanking pipe 12, so that the filling action of the tobacco material can be carried out more effectively, improving the smoothness of feeding, and thus enhancing the user experience. And the pitch of the spiral blade 14 close to the discharge port is smaller, which can generate a certain function of squeezing the tobacco material to the discharge port.

[0055] In one embodiment, along the direction from the discharge port to the feed port, the spiral blade forms at least two threaded segments with sequentially increasing pitches. The threaded segment includes a plurality of threads, and the pitch of the previous threaded segment is increased by 5% - 20% compared to the pitch of the subsequent threaded segment.

[0056] In this embodiment, the direction close to the feed port is defined as "front", and the direction far from the feed port is defined as "rear". The number of threads in each threaded segment can be the same or different.

[0057] When the number of threaded segments is greater than or equal to three, the sizes of the pitches of the threaded segments can be distributed in an arithmetic progression, or the difference between the pitches of adjacent two threaded segments is not equal, as long as the feeding effect can be improved.

[0058] It should be understood that the multi - stage threaded segments are continuously arranged. Therefore, there is a common thread between adjacent two threaded segments. Specifically, when the pitch between a certain thread and the thread in front of it is greater than the pitch between this thread and the thread behind it, then this thread belongs to both the previous threaded segment and the subsequent threaded segment.

[0059] See Figure 10 As shown, taking the spiral blade forming three threaded segments with sequentially increasing pitches as an example, the threaded segment close to the discharge port is named the first threaded segment, the threaded segment far from the discharge port is named the third threaded segment, and the threaded segment between the first threaded segment and the third threaded segment is named the second threaded segment; among them, the first threaded segment includes four threads (R1, R2, R3, R4), the second threaded segment includes two threads (R4, R5), and the third threaded segment includes two threads (R5, R6).

[0060] In one embodiment, the pitch of the threaded segment close to the discharge port is 3 - 6 mm.

[0061] Exemplarily, the pitch of the threaded segment close to the discharge port can be, but is not limited to, 3 mm, 3.2 mm, 3.4 mm, 3.6 mm, 3.8 mm, 4 mm, 4.2 mm, 4.4 mm, 4.6 mm, 4.8 mm, 5 mm, 5.2 mm, 5.4 mm, 5.6 mm, 5.8 mm or 6 mm.

[0062] For example, the pitch of the first threaded section is 6 mm, and the pitch of the second threaded section is increased by 5% to 20% compared to the pitch of the first threaded section, that is, the pitch of the second threaded section is 6.3 to 7.2 mm. The pitch of the third threaded section is increased by 5% to 20% compared to the pitch of the second threaded section, that is, the pitch of the third threaded section is 6.615 to 8.64 mm. The actual dimensions can be processed according to the machining accuracy.

[0063] In one embodiment, the threaded section near the discharge port includes at least three threads, and the pitch between adjacent two threads is equal. In this way, the tobacco material can be slightly extruded, reducing the possibility of local cavities and improving the discharge uniformity.

[0064] Exemplarily, referring to Figure 10 as shown, the threaded section near the discharge port includes four threads (R1, R2, R3, R4).

[0065] In one embodiment, the material of the spiral feeder can be metal, such as food-grade stainless steel or medical-grade stainless steel.

[0066] In other embodiments, the material of the spiral feeder can also be plastic, such as polytetrafluoroethylene.

[0067] In this embodiment, the spiral feeder can be an integrally formed structure, and the shaft and the spiral blade are made of the same material.

[0068] In one embodiment, the diameter of the shaft is not less than 2 mm.

[0069] Exemplarily, when the material of the shaft is metal, the diameter of the shaft is not less than 2 mm; when the material of the shaft is plastic, the diameter of the shaft is not less than 3 mm to maintain sufficient rigidity.

[0070] In one embodiment, referring to Figure 10 as shown, the thickness T of the spiral blade is 1 to 2.5 mm.

[0071] Exemplarily, when the material of the spiral blade is metal, the thickness of the spiral blade is 1 to 1.5 mm; when the material of the spiral blade is plastic, the thickness of the spiral blade is 1.5 to 2.5 mm.

[0072] In this embodiment, the spiral blade can be a structure with equal thickness.

[0073] In one embodiment, the electronic cigarette device further includes a housing 2; the feeding device 1 further includes a first driving mechanism 15, and the first driving mechanism 15 is installed inside the housing 2; the first driving mechanism 15 is in transmission connection with the shaft 13 to drive the shaft 13 to rotate around its own axis.

[0074] Exemplarily, the first driving mechanism 15 is drivingly connected to the rotating shaft 13 through a gear transmission mechanism to drive the rotating shaft 13 to rotate about its own axis.

[0075] It should be noted that the gear transmission mechanism is a prior art and its structure will not be described in detail.

[0076] There are various structural forms of the housing 2. Exemplarily, refer to Figure 2 As shown, the housing 2 includes a first sub-housing 21, a second sub-housing 22, and a third sub-housing 23. The first sub-housing 21 includes a top plate and a first half. The top plate is connected to the first half. The second sub-housing 22 includes a second half. The second plate portion is disposed opposite to the first plate portion to form a hollow cylindrical structure; the first driving mechanism 15 is installed on the top plate; the third sub-housing 23 is connected to the top plate. Refer to Figure 7 As shown, the third sub-housing 23 has a first accommodation cavity 231, and both the first driving mechanism 15 and the gear transmission mechanism are located in the first accommodation cavity 231.

[0077] It should be noted that the structural form of the housing is not limited to the above one, as long as it can accommodate the feeding device 1.

[0078] Of course, the first driving mechanism 15 can also be installed inside the housing through structures such as a mounting plate. Exemplarily, the mounting plate is fixedly connected to the housing, and the first driving mechanism 15 is installed on the mounting plate.

[0079] In some embodiments, the feed hopper 11 is integrally formed with at least a part of the housing 2.

[0080] Refer to Figure 7 As shown, the feed hopper 11 is integrally formed with the first sub-housing 21.

[0081] In some other embodiments, the feed hopper 11 is detachably connected to the housing 2. Such a method facilitates the disassembly of the feed hopper 11, which is convenient for combination and subsequent maintenance and repair.

[0082] In one embodiment, refer to Figure 7 As shown, the feeding device 1 further includes an end cap 16, and the end cap 16 is detachably covered on the inlet of the feed hopper 11.

[0083] In one embodiment, the electronic cigarette device further includes a mounting base 3, a combustion chamber 4, a second driving mechanism 5 and an automatic ignition device. The mounting base 3 has a material receiving position, a combustion position and an ash discharging position. A material receiving hole 311 is provided at the material receiving position, and one end of the blanking pipe 12 with a discharge port extends into the material receiving hole 311. The combustion chamber 4 is mounted on the mounting base 3, and the combustion chamber 4 is provided with a placement cavity 41 for accommodating tobacco material. At the material receiving position, the placement cavity 41 communicates with the material receiving hole 311. The second driving mechanism 5 is mounted on the mounting base 3, and the second driving mechanism 5 is in transmission connection with the combustion chamber 4 so that the placement cavity 41 can be switched between the material receiving position, the combustion position and the ash discharging position. The automatic ignition device is mounted in the housing 2 and is used to ignite the tobacco material in the placement cavity 41 at the combustion position. The soot in the placement cavity 41 can be discharged at the ash discharging position.

[0084] When feeding is required, the second driving mechanism 5 drives the combustion chamber 4 to move to the material receiving position, the placement cavity 41 is aligned with the material receiving hole 311, the first driving mechanism 15 drives the rotating shaft 13 to rotate, the tobacco material in the feeding hopper 11 enters the blanking pipe 12 from the feeding port of the blanking pipe 12 along an inclined direction and lands on the spiral blades 14 of the spiral feeding member. The spiral blades 14 rotate together with the rotating shaft 13 and drive the tobacco material to move together, thereby conveying the tobacco material to the discharge port of the blanking pipe 12. Then the tobacco material falls into the placement cavity 41 through the material receiving hole 311. The second driving mechanism 5 drives the combustion chamber 4 to move to the combustion position, and the automatic ignition device ignites the tobacco material in the placement cavity 41 to generate smoke. After the tobacco material burns out, the generated soot remains in the placement cavity 41. At this time, the second driving mechanism 5 drives the combustion chamber 4 to move to the ash discharging position to discharge the soot in the placement cavity 41.

[0085] Exemplarily, refer to Figure 10 As shown, the length L of the spiral feeding member is not less than 25 mm to feed the tobacco material into the placement cavity 41 of the combustion chamber 4.

[0086] In some embodiments, both the first driving mechanism 15 and the second driving mechanism 5 can be motors.

[0087] In some embodiments, the electronic cigarette device further includes a power supply module, and the power supply module can supply power to the first driving mechanism 15 and the second driving mechanism 5. Exemplarily, the power supply module includes a battery, for example, a lithium-ion battery.

[0088] In one embodiment, refer to Figure 5 As shown, the placement cavity 41 is a through hole penetrating the upper and lower surfaces of the combustion chamber 4. Exemplarily, the cross-sectional shape of the through hole is circular. In this way, there are no dead corners on the cavity wall of the placement cavity 41, which is convenient for removing the soot in the placement cavity 41.

[0089] Exemplarily, the placement cavity 41 is a through hole with a constant diameter.

[0090] It should be noted that the placement cavity 41 can also be a variable diameter through hole. For example, the diameter of the placement cavity 41 gradually decreases from the upper surface to the lower surface of the combustion chamber 4. This method is conducive to ensuring that more smoke materials are concentrated in the area that can be ignited by the automatic ignition device, thereby ensuring that the smoke materials are fully burned and avoiding waste.

[0091] Exemplarily, the mounting seat 3 and the second driving mechanism 5 can both be located inside the housing 2. This approach can reduce the volume of the product and make the appearance of the product more concise and attractive.

[0092] In some embodiments, the side wall of the housing 2 is provided with air inlet holes and heat dissipation holes.

[0093] In some embodiments, the mounting seat 3 is provided with a second accommodating cavity 312 , and the combustion chamber 4 is located in the second accommodating cavity 312 .

[0094] For example, see Figure 9 As shown, the mounting base 3 includes a first sub-base 31 and a second sub-base 32, the second accommodating chamber 312 is arranged on the first sub-base 31, and the first sub-base 31 is provided with a connecting hole for the power output shaft of the second driving mechanism 5 to pass through, and the connecting hole is connected with the second accommodating chamber 312, so that the power output shaft of the second driving mechanism 5 is connected with the combustion chamber 4. The material receiving hole 311 is arranged on the first sub-base 31, and the placement chamber 41 can be aligned with and connected with the material receiving hole 311, so as to add tobacco materials into the placement chamber 41. The second sub-base 32 is plate-shaped, and the second sub-base 32 is fixedly connected with the first sub-base 31 by bolts, nuts or other fasteners, so that the combustion chamber 4 is limited in the second accommodating chamber 312. The circumferential side wall of the placement cavity 41, the upper surface of the second sub-seat 32 and the lower surface of the first sub-seat 31 form a relatively closed space. When the placement cavity 41 filled with granular tobacco is aligned with the automatic ignition device, it can ensure that the granular tobacco is fully burned in the relatively closed space. When not smoking, turn off the automatic ignition device, and the negative pressure in the relatively closed space can ensure that the burning tobacco is extinguished, thereby saving tobacco and reducing waste.

[0095] There are many structures of the combustion chamber 4, for example, see Figure 4 As shown, the combustion chamber 4 is a fan-shaped plate structure. When the placement cavity 41 is staggered with the automatic ignition device, the smoke material in the placement cavity 41 can be placed on the second sub-seat 32.

[0096] In one embodiment, the automatic ignition device includes an electromagnetic coil assembly and an electrode. The electromagnetic coil assembly is installed in the shell 2, and the electrode is connected to the electromagnetic coil assembly. The power supply module supplies power to the electromagnetic coil assembly. After the electromagnetic coil assembly is energized, an arc fire or an ion flame is generated through the electrode, thereby igniting the tobacco material and generating smoke.

[0097] It should be noted that in order to improve the high-temperature resistance performance of the electrode, a tungsten needle is integrated on the electrode to adapt to the high-temperature environment during the combustion process and prevent the electrode from melting.

[0098] In one embodiment, the electromagnetic coil assembly includes a Tesla coil 61, and the number of electrodes is at least one.

[0099] When the number of electrodes is one, the Tesla coil 61 generates an ionic flame through single-electrode discharge to fully burn the tobacco material. Exemplarily, the diameter of the ionic flame can reach 5 mm, and the height can reach 10 mm.

[0100] In this embodiment, the tobacco material can be granular tobacco material with a particle size of 1 - 2 mm after being crushed. The tobacco material falling into the placement cavity 41 is in a loose state as a whole, and there is no need to compact or press the tobacco material, which is convenient for ignition and thus ensures a good combustion effect.

[0101] It should be noted that the number of electrodes can also be multiple. The multiple electrodes can all be single electrodes, or the multiple electrodes can be arranged in pairs. For example, two electrodes arranged in pairs can generate an arc flame to burn the tobacco material. Exemplarily, the cross-sectional shape of the placement cavity is circular. When the electrodes are arranged in pairs, the two electrodes are arranged opposite to each other along the radial direction of the placement cavity.

[0102] See Figure 11 As shown, the radial distance d between the outer circumferential surface of the rotating shaft and the edge of the spiral blade is not less than 2 mm.

[0103] In this embodiment, the radial distance d is set to be not less than 2 mm, which can ensure that the tobacco material smoothly falls on the spiral blade and moves to the outlet of the blanking pipe 12 together with the spiral blade 14, reducing the risk of the tobacco material getting stuck between the rotating shaft and the cavity wall of the placement cavity.

[0104] It should be understood that the sum of the diameter of the rotating shaft, twice the radial distance d, and twice the gap between the edge of the spiral blade and the inner wall of the blanking pipe should be less than or equal to the inner diameter of the placement cavity, so as to ensure that the spiral blade does not interfere with the cavity wall of the placement cavity.

[0105] In this embodiment, due to the adoption of the Tesla coil, compared with ordinary coils, the length and diameter of the generated arc flame are significantly increased, and the combustion force is significantly enhanced, ensuring more complete combustion of the tobacco material.

[0106] In other embodiments, the automatic ignition device includes an electric heating wire or a gas ignition mechanism.

[0107] Exemplarily, the automatic ignition device includes an electric heating wire, and the tobacco material is burned through the electric heating wire.

[0108] Exemplarily, the automatic ignition device includes a gas ignition mechanism, which ignites and burns the tobacco material through the gas ignition mechanism.

[0109] It should be noted that the heating wire and the gas ignition mechanism are prior arts, and their structures will not be described in detail.

[0110] In one embodiment, referring to Figure 2 and Figure 7 as shown, the electronic cigarette device further includes an ash bin 7, an ash discharge pipe 8 and an auxiliary ash discharge mechanism 9; the ash bin 7 is detachably installed on the housing 2; an ash discharge hole 312 is provided at the ash discharge position, and at the ash discharge position, the placement cavity 41 communicates with the ash discharge hole 312; the ash discharge pipe 8 is connected to the mounting seat 3, one end of the ash discharge pipe 8 communicates with the ash discharge hole 312, and the other end of the ash discharge pipe 8 extends into the ash bin 7; the auxiliary ash discharge mechanism 9 includes a thrust mechanism, the thrust mechanism is installed on the mounting seat 3, and at least part of the thrust mechanism can extend into the ash discharge pipe 8 to push the ash in the ash discharge pipe 8 into the ash bin 7. In this way, it can be ensured that the ash falls into the ash bin 7, preventing the ash from scattering outside the housing 2. At the same time, since the ash bin 7 is detachably installed on the housing 2, it is convenient to clean the ash bin 7 separately for reuse.

[0111] Exemplarily, the ash bin 7 is a box-shaped structure with an open top.

[0112] When the second driving mechanism 5 drives the combustion chamber 4 to move to the ash discharge position, the placement cavity 41 communicates with the ash discharge hole 312, and the ash in the placement cavity 41 can smoothly fall from the placement cavity 41 into the ash bin 7 under the action of its own gravity and the thrust mechanism, reducing the adhesion of the ash in the placement cavity 41 and improving the smoothness of ash discharge at the same time.

[0113] In some embodiments, the thrust mechanism includes a push rod, and the push rod can be an electromagnetic push rod or an electric push rod.

[0114] It should be noted that the push rod can also be the piston rod of a telescopic device, where the telescopic device can be a cylinder or an electric rod.

[0115] When ash discharge is required, the thrust mechanism is started, and at least part of the push rod extends into the ash discharge channel, thereby pushing the ash in the placement cavity 41 into the ash bin 7, improving the smoothness of ash discharge and making the ash discharge more thorough.

[0116] In one embodiment, the material of the combustion chamber 4 is ceramic, that is, the cavity wall of the placement cavity 41 is also ceramic. The working temperature of the ceramic combustion chamber is greater than 300 °C, the thermal shock strength is greater than 200 °C, the breakdown resistance is greater than 15 kV / mm, and it has the characteristics of easy cleaning, etc.

[0117] It should be noted that the thermal shock strength is determined by repeating the test in accordance with the steps in the thermal shock and thermal shock strength test method, with a temperature difference increment of 5-10 °C each time, and is represented by the temperature difference when 50% of the test samples are cracked. Among them, the thermal shock and thermal shock strength test method is prior art and will not be elaborated here.

[0118] 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 foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present disclosure.
