Atomizing core, atomizing device and aerosol generating equipment

Abstract

This utility model discloses an atomizing core, an atomizing device, and an aerosol generating apparatus. The atomizing device includes an atomizing core comprising a liquid guide and a heating element. The liquid guide has an atomizing chamber for communicating with an air guide channel in the outer casing. The atomizing chamber is offset towards a first circumferential side of the liquid guide, or the atomizing chamber has a portion of its structure penetrating the first circumferential side of the liquid guide, making the atomizing chamber more offset towards the side wall of the outer casing, thus improving the communication between the atomizing chamber and the air guide channel. The air guide tube of this atomizing device is formed on the side of the casing. Compared to a central rod oil cup structure, the air guide tube occupies less internal space in the casing, increasing the volume of the liquid storage chamber. Furthermore, due to the larger volume of the liquid storage chamber, the aerosol generating matrix can be added from the liquid storage chamber, making addition more convenient. Moreover, this atomizing device has fewer components, which facilitates automated assembly, reduces material costs, and improves product competitiveness.

Description

Technical Field

[0001] This utility model relates to the field of atomization technology, and in particular to an atomizing core, an atomizing device, and an aerosol generating equipment. Background Technology

[0002] The related atomizing technology can be applied to the electronic cigarette industry. With the diversification of market demand, atomizing devices of different volumes and sizes have emerged. Some small-volume open-cup atomizing devices have also become popular. However, currently, these products all use a central rod with a centrally located airflow channel and a centrally located coil, with the atomizing chamber usually positioned in the center. This central rod not only takes up space but also makes it difficult for users to add liquid, mainly due to the small filling space and narrow internal and external gaps. Because of capillary action, the liquid cannot flow freely, leading to difficulty in filling and a poor user experience. Utility Model Content

[0016] In some embodiments, the upper end of the housing is open, and the housing further includes a suction nozzle mounted on the upper end of the housing; the suction nozzle includes a sleeve portion and a suction nozzle portion connected to the sleeve portion, the sleeve portion being connected to the upper end of the housing, and the suction nozzle portion being connected to the air guide tube.

Furthermore, the atomizing device has fewer components, which is conducive to automated assembly, reduces material costs, and improves product competitiveness. Attached Figure Description

[0041] This application discloses an aerosol generating device, including an atomizing device and a power supply device connected to the atomizing device. This aerosol generating device can be used to heat and atomize an aerosol generating matrix into an aerosol for consumer use. The aerosol generating matrix can be, but is not limited to, e-liquid or liquid medicine. The aerosol generating matrix can also be defined as an atomizing liquid.

[0042] The aerosol generating device can be, but is not limited to, electronic cigarettes, atomizing beauty devices, or atomizing pharmaceutical devices. When the aerosol generating device is an electronic cigarette, the atomizing device can be a cartridge structure, and the power supply device can be a cigarette rod structure.

[0043] like Figure 4 , Figures 11 to 14 As shown, this utility model discloses an atomizing core 21, which includes a liquid guide 211 and a heating element 212. The liquid guide 211 has an atomizing chamber 2111 for communicating with an air guide channel of the outer shell 10, such as... Figure 4 , Figure 11 as well as Figure 12 As shown, the atomizing chamber 2111 is disposed biased towards the first circumferential side 211a of the liquid guide 211, or, as... Figure 13 and Figure 14 As shown, the atomizing cavity 2111 penetrates part of the structure of the first side surface 211a of the liquid guide 211 in the circumferential direction, so that the atomizing cavity 2111 is more biased towards the side wall of the outer shell 10, making the connection between the atomizing cavity 2111 and the air guide channel smoother; the heating element 212 is attached to or embedded in the inner wall surface of the atomizing cavity 2111.

[0044] like Figure 11 and Figure 12 As shown, in some embodiments, the atomizing cavity 2111 is disposed biased towards the first circumferential side surface 211a of the liquid guide 211, and the wall thickness of the sidewall of the atomizing cavity 2111 opposite to the first side surface 211a is greater than 0.1 mm. For example, the wall thickness of the sidewall of the atomizing cavity 2111 opposite to the first side surface 211a can be 0.11 mm, 0.12 mm, 0.13 mm, 0.14 mm, 0.15 mm, 0.16 mm, 0.17 mm, 0.18 mm, 0.19 mm, or 0.2 mm. The atomizing cavity 2111 is disposed biased towards the first circumferential side surface 211a of the liquid guide 211, and the wall thickness of the sidewall of the atomizing cavity 2111 opposite to the first side surface 211a is 0.1 mm to 3.0 mm. The wall thickness of the sidewall opposite to the first side 211a of the atomizing chamber 2111 can be relatively small, making the structure of the atomizing chamber 2111 more complete. At the same time, the sidewall opposite to the first side 211a of the atomizing chamber 2111 can fit more closely to the inner sidewall of the outer shell 10, especially the sidewall of the outer shell 10 where the shell 11 is connected to the isolation part 111, thereby improving the alignment of the atomizing chamber 2111 with the air guide channel.

[0045] In some embodiments, the liquid guide 211 is further provided with a liquid storage tank 2112. The liquid storage tank 2112 is disposed opposite to the liquid guide hole 31. One or more liquid guide holes 31 and one or more liquid storage tanks 2112 may be provided; for example, two liquid guide holes 31 may be provided. Preferably, one liquid storage tank 2112 may be provided. The liquid storage tank 2112 may be approximately arc-shaped, C-shaped, or U-shaped. The liquid storage tank 2112 may be a non-through tank, i.e., a blind hole structure. The aerosol generating matrix in the liquid storage chamber 13 can enter the liquid storage tank 2112 through the liquid guide hole 31, ensuring that the liquid guide 211 is always wetted by the aerosol generating matrix, thus preventing the atomizing core 21 from dry-burning due to a lack of aerosol generating matrix.

[0046] In some embodiments, the liquid guide 211 has a second surface 211b disposed opposite to the first surface 211a, and the liquid storage tank 2112 is disposed biased toward the second surface 211b.

[0047] In some embodiments, the atomizing cavity 2111 axially extends through the upper and lower surfaces of the liquid guide 211, making the airflow within the atomizing cavity 2111 smoother. The atomizing cavity 2111 can be a columnar through-groove structure, and its cross-sectional shape can be, but is not limited to, square or circular. The cross-sectional shape of the atomizing cavity 2111 can also be a trapezoid or rhombus or other polygons, without specific limitations.

[0048] In some embodiments, the liquid-conducting structure 211 may be generally square columnar. The liquid-conducting structure 211 includes, but is not limited to, porous ceramics.

[0049] See Figures 1 to 10 This utility model discloses an atomizing device, which may include, but is not limited to, a small-volume atomizing device, wherein the liquid storage volume of the small-volume atomizing device is approximately 1 ml to 2 ml.

[0050] The atomizing device may include a housing 10 and an atomizing assembly 20. The housing 10 includes a shell 11, and the inner cavity of the shell 11 is provided with a partition 30. The partition 30 defines the inner cavity of the shell 11 into a first chamber and a second chamber, such as... Figure 5 As shown, the first chamber may be located above the second chamber. The housing 11 is connected to an isolation section 111 on the side wall of the first chamber. The isolation section 111 and the side wall of the housing 11 connected thereto cooperate to form a gas guide tube 12. The portion of the first chamber excluding the gas guide tube 12 forms a liquid storage chamber 13 for storing the aerosol generation matrix. The partition 30 is provided with a liquid guide hole 31 and a gas guide hole 32. The liquid guide hole 31 is connected to the liquid storage chamber 13, and the gas guide hole 32 is connected to the gas guide tube 12 to form a gas guide channel.

[0051] Combination Figure 4 and Figure 5 As shown, the atomizing assembly 20 is installed in the second chamber. The atomizing assembly 20 includes the atomizing core 21 of the above embodiment. Further, the atomizing core 21 includes a liquid guide 211 and a heating element 212. The liquid guide 211 is disposed opposite to the partition 30. The first side 211a of the liquid guide 211 is biased towards the side wall of the housing 11 connected to the isolation part 111. The liquid guide 211 has an atomizing cavity 2111. The heating element 212 is attached to or embedded in the inner wall surface of the atomizing cavity 2111. The atomizing cavity 2111 is disposed biased towards the air guide tube 12. The atomizing cavity 2111 is connected to the air guide hole 32, and then the atomizing cavity 2111 is connected to the air guide tube 12.

[0052] In this application, the air guide tube 12 of the atomizing device is formed on the side of the housing 11. Compared with the central rod oil cup structure, the air guide tube 12 occupies less internal space in the housing 11, which can increase the volume of the liquid storage chamber 13. In addition, since the liquid storage chamber 13 has a larger volume, the aerosol generation matrix can be added from the liquid storage chamber 13, making the addition more convenient. Furthermore, the atomizing device has fewer components, which is conducive to automated assembly, reduces material costs, and improves product competitiveness.

[0053] Combination Figure 4 and Figure 5 As shown, in some embodiments, the housing 11 may be a hollow columnar structure, and the cross-sectional shape of the housing 11 may be approximately rectangular. The housing 11 may include a first sidewall, a second sidewall, a third sidewall, and a fourth sidewall connected in sequence. The first sidewall and the third sidewall are disposed opposite to each other, and the second sidewall and the fourth sidewall are disposed opposite to each other. The isolation portion 111 may be approximately arc-shaped, C-shaped, or U-shaped. The isolation portion 111 may be connected to at least a portion of the inner surface of the first sidewall. The isolation portion 111 and the first sidewall together define the air guide tube 12. The portion of the first chamber excluding the air guide tube 12 forms a liquid storage chamber 13. The atomizing chamber 2111 is biased towards the first sidewall of the housing 11, and the first side surface 211a of the liquid guide 211 may be in contact with the first sidewall of the housing 11.

[0054] Combination Figure 4 and Figure 5 As shown, in some embodiments, the liquid guide 211 may be a generally square columnar structure, and the shape and size of the liquid guide 211 are adapted to the second chamber. The atomizing chamber 2111 may be disposed on one side biased towards the liquid guide 211. The axis of the atomizing chamber 2111 is parallel to the axis of the air guide tube 12, or the axis of the atomizing chamber 2111 coincides with the axis of the air guide tube 12. A vertical straight air passage can reduce friction around the airflow and improve the vapor reduction degree. Preferably, the atomizing chamber 2111 may be a cylindrical structure.

[0055] Combination Figure 4 and Figure 5 As shown, furthermore, the cross-sectional dimensions of the air guide hole 32 are uniformly arranged from bottom to top; for example, the inner cavity shape of the air guide hole 32 can be cylindrical. Alternatively, the cross-sectional dimensions of the air guide hole 32 gradually decrease from bottom to top, such as... Figure 5As shown, the longitudinal section of the air guide hole 32 can be approximately trapezoidal. Since the air guide tube 12 is located on the inner side of the housing 11, and the liquid guide 211 needs to occupy a certain space, the atomization chamber 2111 of the liquid guide 211 exists in the case of the air guide tube 12 being out of axis. The air guide hole 32 adopts a structure that gradually decreases from bottom to top, which can better guide the aerosol generated by the atomizing core 21 into the air guide tube 12.

[0056] Combination Figure 4 and Figure 5 As shown, in some embodiments, the cross-sectional dimension of the lower end of the inner cavity of the air guide hole 32 may be greater than or equal to the cross-sectional dimension of the upper end of the atomizing chamber 2111, and the cross-sectional dimension of the upper end of the inner cavity of the air guide hole 32 may be greater than or equal to the cross-sectional dimension of the lower end of the inner cavity of the air guide tube 12. Of course, the shape and size of the air guide hole 32 can be selected and set according to actual needs, and are not specifically limited here.

[0057] Combination Figure 4 and Figure 5 As shown, in some embodiments, the liquid guide 211 is further provided with a liquid storage tank 2112, which is disposed opposite to the liquid guide hole 31. One or more liquid guide holes 31 and one or more liquid storage tanks 2112 can be provided; for example, two liquid guide holes 31 can be provided. Preferably, one liquid storage tank 2112 can be provided. The liquid storage tank 2112 can be approximately arc-shaped, C-shaped, or U-shaped, and can be a non-through tank, i.e., a blind-hole tank structure. The aerosol generating matrix in the liquid storage cavity 13 can enter the liquid storage tank 2112 through the liquid guide hole 31, ensuring that the liquid guide 211 is always wetted by the aerosol generating matrix, thus preventing the atomizing core 21 from dry-burning due to a lack of aerosol generating matrix.

[0058] Combination Figure 4 and Figure 5 As shown, in some embodiments, the partition 30 is detachably installed within the housing 11. For example, the partition 30 may be an interference fit within the housing 11. Alternatively, the partition 30 may be fixedly connected to the housing 11.

[0059] Combination Figures 5 to 8In some embodiments, the inner wall surface of the housing 11 is provided with a plurality of first limiting protrusions 112, which extend axially along the housing 11. The lower end face of the first limiting protrusion 112 is at the same horizontal plane as the lower end face of the isolation portion 111. The upper surface of the partition member 30 abuts against the lower end face of the first limiting protrusion 112 and the lower end face of the isolation portion 111. Preferably, the first limiting protrusion 112 may be generally rectangular columnar in shape, and the inner wall surfaces of the second, third, and fourth side walls of the housing 11 may all be provided with first limiting protrusions 112 to facilitate sufficient limiting of the partition member 30. Further, both the lower end face of the first limiting protrusion 112 and the isolation portion 111 may be planar to provide sufficient contact area with the upper surface of the partition member 30, thereby improving the limiting effect. Of course, the shape, location, and number of the first limiting protrusion 112 can be selected and set according to actual needs, and no specific limitation is made here.

[0060] Combination Figures 5 to 8 In some embodiments, the outer surface of the isolation portion 111 is provided with a second limiting protrusion 113. The lower end face of the second limiting protrusion 113 is at the same horizontal plane as the lower end face of the isolation portion 111. The upper surface of the partition 30 abuts against the lower end face of the second limiting protrusion 113, which can better limit the partition 30. In addition, the second limiting protrusion 113 can also act as a baffle, so that when the atomizing device is shaken, the aerosol generating matrix in the liquid storage chamber 13 collides with the second limiting protrusion 113 and becomes more uniform, avoiding the precipitation of some substances in the aerosol generating matrix.

[0061] The outer surface of the isolation portion 111 here refers to the surface of the isolation portion 111 facing the third sidewall of the housing 11. The shape of the second limiting protrusion 113 can be approximately triangular. Preferably, when there are two liquid guiding holes 31, the two liquid guiding holes 31 can be on both sides of the longitudinal plane where the second limiting protrusion 113 is located. Of course, the shape, location, and number of the second limiting protrusion 113 can be selected according to actual needs, and are not specifically limited here. Of course, in some embodiments, the second limiting protrusion 113 may not be provided, so that the liquid storage cavity 13 retains sufficient volume.

[0062] Combination Figures 4 to 8In some embodiments, the partition 30 may be a flat columnar structure, and the shape and size of the partition 30 are adapted to the shape and size of the inner cavity of the housing 11. Further, the partition 30 may be a silicone partition, meaning it may be made of silicone material. The liquid guide 211 may be at least one of porous ceramic or liquid-guiding cotton. When porous ceramic is used for the liquid guide 211, using silicone material for the partition 30 can improve the sealing effect and protect the liquid guide 211 from brittleness. Of course, the liquid guide 211 may also be made of liquid-guiding cotton; no specific limitation is made here.

[0063] In some embodiments, the partition 30 is fixedly connected to the housing 11. The partition 30 may be an integral structure with the housing 11. In this case, the partition 30 may be made of silicone or plastic. When the liquid guide 211 is made of porous ceramic, the partition 30 may be made of silicone. Alternatively, a sealing protection member may be provided between the partition 30 and the liquid guide 211. The shape and size of the sealing protection member are the same as or similar to those of the partition 30. The sealing protection member may be made of silicone and can also protect the porous ceramic.

[0064] like Figure 4 As shown, in some embodiments, the atomizing component 20 further includes a base 22, which may be generally cylindrical in shape. The base 22 may include a bottom wall 221 and a surrounding wall 222 connected to the upper surface of the bottom wall 221. The upper end surface of the surrounding wall 222 abuts against the lower surface of the partition 30. A supporting wall 223 is provided in the middle of the inner side of the surrounding wall 222, and the liquid guide 211 is disposed on the supporting wall 223.

[0065] In some embodiments, a notch 2221 is provided on one side of the enclosure 222, and the bottom surface 22211 of the notch 2221 is connected to the supporting wall 223. The side of the enclosure 222 may be arranged opposite to the first side wall of the housing 11, so that after the atomizing core 21 is installed on the base 22, the axis of the atomizing chamber 2111 of the liquid guide 211 can be more biased towards the axis of the air guide tube 12, or even the axis of the atomizing chamber 2111 of the liquid guide 211 coincides with the axis of the air guide tube 12, which can improve the air guiding effect.

[0066] like Figure 4 and Figure 5As shown, in some embodiments, the outer surface of the enclosure 222 is further provided with an annular groove 224, and the atomizing assembly 20 further includes a sealing ring 23 fitted onto the groove 224. The sealing ring 23 may be, but is not limited to, a silicone sealing ring. Preferably, the groove 224 is located below the bottom surface 22211 of the notch 2221, and the number of grooves 224 may be one or more, and the number of sealing rings 23 is the same as the number of grooves 224.

[0067] like Figure 4 and Figure 5 As shown, in some embodiments, the bottom wall 221 and the surrounding wall 222 together define a receiving groove, in which a liquid-absorbing element 24 is provided. The liquid-absorbing element 24 may be generally columnar, and may include, but is not limited to, absorbent cotton. Providing the liquid-absorbing element 24 can improve the anti-leakage effect.

[0068] like Figure 4 and Figure 5 As shown, in some embodiments, an air inlet 221 (e.g., air inlet 2211) may be provided on the bottom wall 221 of the base 22. Figure 5 As shown in the diagram, the liquid-absorbing component 24 may be provided with airflow holes 241 and several second electrode holes 242. The air inlet 2211 is opposite to and connected to the airflow holes 241. The first electrode holes and the second electrode holes 242 are opposite to and connected to each other. The atomizing assembly 20 also includes several electrode posts 25, which are inserted through the first electrode holes and the second electrode holes 242 to connect with the pins (not shown) of the heating element 212. There may be two electrode posts 25. The pins of the heating element 212 can protect the positive and negative electrode pins. The electrode posts 25 can be electrically connected to a power supply device.

[0069] like Figure 4 and Figure 5 As shown, in some embodiments, the base 22 is detachably connected to the housing 11. For example, the base 22 may be interference-fitted with the housing 11, or the base 22 may be snap-fitted to the housing 11.
