The present invention constructs an aerosol generating device, which can use microwaves to heat an aerosol generating product 33 (see FIG. 6 ) to generate aerosol by atomization, so as to be inhaled or inhaled by a user.

The aerosol generating device may include a microwave generating component (not shown), a microwave heating component and an aerosol generating product component 3. The microwave generating component is used to generate microwaves; the microwave heating component forms a heating space 1131 (see FIG. 2 ) in itself by connecting the microwave to the microwave generating component (it can be understood that after the microwave generating component is connected to the microwave, it continuously resonates inside to form a microwave field, and the heating space 1131 is the area in the microwave field where the intensity meets the requirements); the aerosol generating product component 3 is coaxially installed in the microwave heating component, and the aerosol generating product component 3 includes a plurality of aerosol generating products 33, which can rotate in a circle around the central axis of the microwave heating component relative to the heating space 1131, so that the heating space 1131 can be selectively made to act on a single or part (part means some individuals in the whole) of the aerosol generating product 33, so as to achieve a selective microwave heating effect. By selectively heating the aerosol generating product 33 with microwaves, the selected aerosol generating product 33 can be completely heated and atomized in a relatively short time, thus overcoming the technical defects of being unable to heat the aerosol generating product 33 uniformly and heating it slowly.

Please refer to Figures 1 and 2 together, which show the overall structure of the aerosol generating product assembly 3 and the microwave heating assembly in Example 1 of the present invention and the matching relationship between the two.

As shown in Fig. 1 and Fig. 2, the overall shape of the microwave heating assembly is roughly cylindrical. Of course, the microwave heating assembly is not limited to the cylindrical shape, and it can also be in other shapes such as square column, elliptical column, etc. The microwave heating assembly includes a microwave heating body 1 and a rotating unit 2, wherein the microwave heating body 1 can be connected to the microwave generating assembly to receive microwaves, and the rotating unit 2 is coaxially, detachably and rotatably installed on the microwave heating body 1, and is used to drive the aerosol generating product assembly 3 to rotate around the central axis of the microwave heating assembly.

It can be understood that the rotating unit 2 is not necessary in this embodiment, and is applied in this embodiment as a preferred technical solution. In the embodiment without the rotating unit 2, the microwave heating body 1 can directly touch the rotating aerosol generating product assembly 3.

In this embodiment, the microwave heating body 1 includes an outer conductor unit 11, an inner conductor unit 13 and a dielectric unit 12. The outer conductor unit 11 defines a first receiving cavity 113, and the inner conductor unit 13 and the dielectric unit 12 are arranged in the first receiving cavity 113; one end of the inner conductor unit 13 extends out of the outer conductor unit 11 and is connected to the microwave generating assembly to receive microwaves, and the other end of the inner conductor unit 13 is arranged in the first receiving cavity 113 to form a strong microwave field around it; the dielectric unit 12 is arranged between the outer conductor unit 11 and the inner conductor unit 13, and is used to fix and support the inner conductor unit 13, and to separate the outer conductor unit 11 from the inner conductor unit 13.

As shown in Fig. 3 and Fig. 4, the outer conductor unit 11 is in a cylindrical shape, and has a first open end 111 and a first closed end 112 opposite to the first open end 111. The first receiving cavity 113 is between the first open end 111 and the first closed end 112, and the aerosol generating product assembly 3 can be loaded into the first receiving cavity 113 from the first open end 111. Optionally, the outer conductor unit 11 includes a first barrel section 114 and a second barrel section 115 coaxially connected to the first barrel section 114, and the first barrel section 114 and the second barrel section 115 are both in a cylindrical shape, and the inner diameters of the two are equivalent, and they jointly form a cylindrical first receiving cavity 113; wherein, the end of the first barrel section 114 away from the second barrel section 115 is an open structure, which serves as the first open end 111 of the outer conductor unit 11, and the end of the second barrel section 115 away from the first barrel section 114 is a closed structure, which serves as the first closed end 112 of the outer conductor unit 11. Secondly, the outer diameter of the first barrel section 114 is smaller than the outer diameter of the second barrel section 115 , and a first step surface 116 is formed between the first barrel section 114 and the second barrel section 115 .

The outer conductor unit 11 further includes a first vent hole 117 radially penetrating the peripheral wall of the second barrel section 115 , the first vent hole 117 connects the external environment of the outer conductor unit 11 with the first receiving cavity 113 , and the first vent hole 117 is opposite to one end of the inner conductor unit 13 for forming a strong microwave field.

The first vent hole 117 includes a first hole section 1171 and a second hole section 1172 coaxially connected to the first hole section 1171. The first hole section 1171 is relatively adjacent to the outer peripheral wall of the second barrel section 115, and the first hole section 1171 is a cylindrical channel, and its aperture is larger than the aperture of the second hole section 1172. The second hole section 1172 is a cylindrical channel, and the aperture size of the second hole section 1172 is between 0.1 mm and 0.3 mm, preferably 0.2 mm.

The outer conductor unit 11 also includes a socket 119 disposed on the end wall of the second barrel section 115 (the first closed end 112). The socket 119 axially penetrates the end wall of the second barrel section 115 (the first closed end 112) and is used to cooperate with the inner conductor unit 13 and the dielectric unit 12 to fix the inner conductor unit 13 and the dielectric unit 12 in the first receiving cavity 113.

The outer conductor unit 11 further includes a plurality of first assembly holes 118 spaced and evenly distributed on the periphery of the first step surface 116, and the first assembly holes 118 are used to cooperate with the rotating unit 2 so that the rotating unit 2 is installed on the outer conductor unit 11. Optionally, any first assembly hole 118 is formed by extending longitudinally downward along the periphery of the first step surface 116.

In this embodiment, the outer conductor unit 11 can be made of a conductive metal material, preferably aluminum alloy or copper. In addition, the outer conductor unit 11 can also be made by coating the inner wall of a non-conductive body with a conductive coating.

As shown in FIG. 3 and FIG. 4 , the dielectric unit 12 includes a dielectric cylinder 121. The dielectric cylinder 121 is cylindrical and is disposed in the second barrel section 115. The outer diameter of the dielectric cylinder 121 is equivalent to the inner diameter of the second barrel section 115. The dielectric cylinder 121 has a second open end 1211, a second closed end 1212 opposite to the second open end 1211, and a second receiving cavity 1213 between the second open end 1211 and the second closed end 1212. The second receiving cavity 1213 can accommodate part of the structure of the inner conductor unit 13. The bottom end face of the dielectric cylinder 121 (the end face of the second closed end 1212 facing the first closed end 112) abuts against the inner end face of the second barrel section 115 (the end face of the first closed end 112 facing the first open end 111), and the outer peripheral surface of the dielectric cylinder 121 fits the inner peripheral side surface of the second barrel section 115.

The inner end surface of the dielectric cylinder 121 (the end surface of the second closed end 1212 facing the second open end 1211) abuts against the inner conductor unit 13 and supports the inner conductor unit 13. Preferably, the inner end surface of the dielectric cylinder 121 is a second conical surface 1214, and the diameter of the second conical surface 1214 gradually decreases toward the first closed end 112 to match the surface of the inner end surface of the inner conductor unit 13 abutting against the dielectric cylinder 121. The conical transition of the second conical surface 1214 makes the microwave field change smoother and reduces the concentration of the local field, thereby making it easier to achieve impedance matching and reducing the overall reflection.

The media unit 12 further includes a fixing column 122 , which is coaxially integrated with the bottom end surface of the media cylinder 121 and is used to be embedded in the bottom end wall of the second cylinder section 115 (the end wall of the first closed end 112 ) to fix the media cylinder 121 in the second cylinder section 115 .

The dielectric unit 12 further includes a through-channel 123 disposed on the dielectric tube 121 and the fixing column 122, and the through-channel 123 is used for one end of the inner conductor unit 13 for receiving microwaves to extend outside the outer conductor unit 11. Optionally, the through-channel 123 is a cylindrical channel, axially penetrating the bottom end surface of the dielectric tube 121 and the fixing column 122, so as to connect the second receiving cavity 1213 with the outside of the outer conductor unit 11.

In this embodiment, the dielectric unit 12 is preferably made of a material that does not absorb microwaves, such as polytetrafluoroethylene.

As shown in FIG. 3 and FIG. 4 , the inner conductor unit 13 includes a conductor plate 131 , a radiation structure 132 and a connecting column 133 .

In this embodiment, the conductor disc 131 is in the shape of a disc, and is disposed in the dielectric cylinder 121. The diameter of the conductor disc 131 is equivalent to the inner diameter of the dielectric cylinder 121, and the outer peripheral side surface of the conductor disc 131 is in contact with the inner peripheral side surface of the dielectric cylinder 121. The conductor disc 131 includes a first end surface 1311 and a second end surface 1312 opposite to the first end surface 1311. The first end surface 1311 faces the first open end 111, and the second end surface 1312 is opposite to the inner end surface of the dielectric cylinder 121. Preferably, the first end surface 1311 is a plane, and the second end surface 1312 is a first conical surface, and its diameter gradually decreases toward the first closed end 112. The first conical surface is adapted to the second conical surface 1214, and the diameters of the two are equivalent, and the first conical surface is in contact with the second conical surface 1214. It can be understood that the design of the first conical surface and the second conical surface 1214 can adjust the impedance matching between the standard SMA connector of the microwave generating assembly and the inner conductor unit 13, reduce the reflected energy of the microwave, and increase the efficiency of the aerosol generating product 33 in absorbing energy.

The radiation structure 132 includes a main radiation antenna 1321 and a plurality of secondary radiation antennas 1322. Part of the structure of the main radiation antenna 1321 and the plurality of secondary radiation antennas 1322 are arranged in the dielectric tube 121, and the main radiation antenna 1321 and the plurality of secondary radiation antennas 1322 are connected to the adjacent edge of the first end surface 1311, and are evenly and spacedly arranged in the circumferential direction of the first end surface 1311.

The main radiating antenna 1321 is longitudinally elongated and stands on the first end surface 1311 in a direction parallel to the central axis of the outer conductor unit 11. The axial length of the main radiating antenna 1321 is greater than the axial length of any radiating secondary antenna 1322. As shown in Figures 2, 3 and 5, the main radiating antenna 1321 includes an antenna connecting portion 1321a and an antenna action portion 1321b. The antenna connecting portion 1321a is longitudinally elongated and arc-shaped and is arranged in the dielectric cylinder 121. The bottom end (first fixed end) of the antenna connecting portion 1321a is fixed to the first end surface 1311, and the top end (second fixed end) thereof extends longitudinally upward for connection with the antenna action portion 1321b. Preferably, the top end surface of the antenna connecting portion 1321a is flush with the top end surface of the dielectric cylinder 121 (the end surface of the second open end 1211).

As shown in Fig. 5, the antenna action portion 1321b is in a longitudinal arc-shaped structure, which is integrated with the top end of the antenna connection portion 1321a, extends out and is located outside the dielectric tube 121.

The positioning part 23 is fixedly arranged on the outer conductor unit 11, and part of its structure is arranged on the rotating ring 22. By cooperating with the rotating ring 22, the rotation angle of the rotating cylinder 21 is controlled and limited.

It can be understood that the rotating ring 22 and the positioning part 23 are not essential in the present invention, and the rotating ring 22 and the positioning part 23 are applied in this embodiment as an optional technical solution. The cooperation of the rotating ring 22 and the positioning part 23 with the rotating cylinder 21 can ensure that the aerosol generating product 33 is directly opposite to the antenna action part 1321b of the main radiation antenna 1321, so that the aerosol generating product 33 can obtain the best heating effect.

As shown in FIG. 3 and FIG. 4 , the positioning part 23 is fixedly mounted on the first step surface 116 of the outer conductor unit 11 and is relatively located on the outer periphery of the rotating ring 22. The positioning part 23 includes a ring-shaped positioning base 232, a plurality of positioning protrusions 231 and a plurality of fixing protrusions 233 protruding from both sides of the axial end surface of the positioning base 232.

The fixing protrusions 233 are used to be correspondingly inserted into the first assembly holes 118 of the first outer conductor unit 11 to relatively fix the positioning protrusions 231 on the outer conductor unit 11.

As shown in Figures 6 and 7, the aerosol generating product assembly 3 includes a plurality of aerosol generating products 33 and a rotating body 31 for carrying the plurality of aerosol generating products 33. The rotating body 31 is detachably arranged on the outer conductor unit 11 and can rotate around the central axis of the outer conductor unit 11 relative to the inner conductor unit 13.

The aerosol generating products 33 are sheet-shaped structures, preferably arc-shaped sheets. The ingredients of the aerosol generating products 33 may include processed plant leaves.

The rotating body 31 is generally cylindrical, and its maximum outer diameter is smaller than the diameter of the first receiving chamber 113 and is equivalent to the diameter of the medium cylinder 121. A plurality of receiving positions 3113a are formed on the rotating body 31, and the receiving positions 3113a are evenly spaced and distributed around the rotating body 31, and are used to receive a plurality of aerosol generating products 33 respectively.

When the rotating body 31 is installed on the outer conductor unit 11, the bottom end of the rotating body 31 abuts against the top end surface of the dielectric tube 121 to support the rotating body; and multiple accommodating positions 3113a are relatively located at the same height as the antenna action part 1321b of the main radiating antenna 1321, and one of the accommodating positions 3113a is relatively located between the antenna action part 1321b and the peripheral wall surface of the first accommodating cavity 113.

In this embodiment, the rotating body 31 includes a receiving section 313, a bearing section 311, a base 312, and an aerosol processing material piece 314 located in the receiving section 313, which are coaxially connected in sequence. The bearing section 311 is used as a carrier of a plurality of aerosol generating products 33, and a plurality of accommodating positions 3113a are located on the bearing section 311; the receiving section 313 is used to accommodate the aerosol processing material piece 314 therein, to cooperate with the rotating unit 2 to drive the plurality of aerosol generating products 33 to rotate around the central axis of the rotating body 31, and to abut against the top of the aerosol generating product 33 to limit the aerosol generating product 33 to be located in the accommodating position 3113a; the base 312 is installed at one end of the bearing section 311 away from the receiving section 313, and is used to abut against the bottom end of the aerosol generating product 33 to limit the aerosol generating product 33 to be located in the accommodating position 3113a. The aerosol processing material piece 314 includes a cooling material piece 3141 and a filtering material piece 3142. The cooling material piece 3141 is used to reduce the temperature of the aerosol when the aerosol flows through, and the filtering material piece 3142 is used to filter harmful components in the aerosol and to adjust the suction resistance.

As shown in FIG6 and FIG7, the bearing section 311 is cylindrical, and both ends of the axial direction are open structures. A plurality of accommodating grooves 3113 recessed inwardly are provided on the outer peripheral wall surface of the bearing section 311, and the accommodating grooves 3113 are evenly spaced and distributed on the bearing section 311. When the rotating body 31 is mounted on the outer conductor unit 11, the antenna action portion 1321b extends into the central channel 3114 of the bearing section 311 and fits against the inner peripheral wall surface of the bearing section 311.

Each accommodating groove 3113 is a through groove, which is formed with a first notch 3113b located at the periphery of one end (first connecting end 3111) of the bearing section 311 away from the receiving section 313, a second notch 3113c located at the periphery of one end (second connecting end 3112) of the bearing section 311 away from the base 312, and an accommodating position 3113a between the first notch 3113b and the second notch 3113c. The shape and size of the accommodating position 3113a are adapted to the shape and size of the aerosol generating article 33. In the present embodiment, the accommodating position 3113a is in the shape of an arc sheet, and its depth direction is perpendicular to the central axis of the bearing section 311. It can be understood that the second notch 3113c is connected to the second connecting end 3112 through the receiving section 313, which completely/partially blocks the second notch 3113c. The aerosol generating product 33 can be inserted into the accommodating position 3113a from the first notch 3113b, and the first notch 3113b is blocked by the base 312, so that the aerosol generating product 33 is firmly installed in the accommodating position 3113a.

The rotating body 31 also includes a plurality of third ventilation holes (not shown) penetrating the peripheral wall of the bearing portion and distributed in the circumferential direction of the peripheral wall of the bearing portion; the plurality of accommodation positions 3113a are connected to the central channel 3114 of the bearing portion through the plurality of third ventilation holes.

As shown in Fig. 6 and Fig. 7, the base 312 is annular and is detachably mounted (e.g., snap-fitted or threadedly connected) on the first connection end 3111 of the bearing section 311. Optionally, the top end surface of the base 312 is attached to the end surface of the first connection end 3111 of the bearing section 311, and the inner circumferential wall surface of the base 312 is flush with the inner circumferential wall surface of the bearing section 311. At the same time, the outer diameter of the base 312 is greater than the maximum outer diameter of the bearing section 311, so as to block the first notch 3113b of each accommodating groove 3113.

Preferably, the base 312 may be made of at least one of acetate, cotton, and paper, which is used to absorb oily substances generated when the aerosol generating product 33 is heated to avoid corrosion of metal conductors, such as the outer conductor unit 11 and the inner conductor unit 13.

A plurality of second vent holes 3121 are formed on the base 312 and radially penetrate the peripheral wall thereof. The plurality of second vent holes 3121 are arranged at intervals and evenly in the circumference of the base 312. At the same time, the positions between the plurality of second vent holes 3121 and the plurality of receiving grooves 311 are correspondingly located on the same longitudinal line. It can be understood that when the rotating body 31 is mounted on the outer conductor unit 11, the first vent hole 117 on the outer conductor unit 11 can be opposite to one of the second vent holes 3121 to connect the outside of the outer conductor unit 11 with the central channel 3114 of the bearing section 311, and then allow the airflow to flow from the outside of the outer conductor unit 11 into the central channel 3114 of the bearing section 311.

As shown in FIG. 6 and FIG. 7 , the receiving section 313 is cylindrical and defines a receiving space 3131. The receiving space 3131 is cylindrical and is used to receive the aerosol processing material piece 314. The receiving section 313 is connected to an end (the second connecting end 3112) of the bearing section 311 away from the base 312, and is connected to the central channel 3114 of the bearing section 311. The inner diameter of the receiving section 313 is equivalent to the inner diameter of the bearing section 311.

A plurality of first engaging grooves 3134 are formed on the outer wall surface of the receiving section 313 and are evenly spaced and distributed in the circumferential direction thereof. The first engaging grooves 3134 are used to cooperate with the plurality of ridges 214 on the rotating cylinder 21. It can be understood that when the rotating body 31 is mounted on the outer conductor unit 11, part of the ridges 214 are engaged with part of the first engaging grooves 3134. Optionally, each first engaging groove 3134 is a longitudinal through groove, the extension direction of which is parallel to the central axis of the receiving section 313, and the depth direction is perpendicular to the central axis direction of the rotating body 31. Secondly, in this embodiment, the first engaging grooves 3134 correspond to the receiving grooves 3113 longitudinally and coaxially one by one, and the width (length in the circumferential direction) of the first engaging grooves 3134 is smaller than the width of the receiving grooves 3113, so that the end surface of one end of the receiving section 313 connected to the bearing section 311 blocks part of the second notch 3113c.

The receiving section 313 includes an axially connected cooling section 3132 and a filtering section 3133, both of which are cylindrical and have comparable sizes; the cooling section 3132 is connected to the first connecting end 3111 of the supporting section 311, and is used to receive the cooling material piece 3141 therein; the filtering section 3133 is connected to one end of the cooling section 3132 away from the supporting section 311, and is used to receive the filtering material piece 3142 therein.

As shown in Fig. 6 and Fig. 7, the aerosol generating product assembly 3 further comprises a nozzle 32, which is connected to one end of the receiving section 313 away from the bearing section 311, and the interior of the nozzle 32 is connected to the receiving space 3131. When the aerosol generating product assembly 3 is mounted on the microwave heating assembly, the nozzle 32 is located outside the outer conductor unit 11.

Optionally, the suction nozzle 32 includes an axially connected fifth barrel section 321, a sixth barrel section 322, and an expansion barrel section 323 between the fifth barrel section 321 and the sixth barrel section 322. The fifth barrel section 321 is relatively far away from the rotating body 31, and the fifth barrel section 321 is cylindrical, and its outer diameter is smaller than the sixth barrel section 322. The user can hold the fifth barrel section 321 in his mouth and make a suction action. Of course, the fifth barrel section 321 is not limited to a cylindrical shape, but can also be a flat cylindrical shape, because the flat suction nozzle 32 can better fit the lips, and can make the smoke more concentrated, and the suction experience is better. The sixth barrel section 322 is relatively adjacent to the rotating body 31, and it is cylindrical, and its inner diameter is slightly larger than the maximum outer diameter of the filter section 3133. The suction nozzle 32 is fixed to the outer periphery of one end of the filter section 3133 away from the cooling section 3132 by the sixth barrel section 322. The expansion barrel section 323 is used to connect the fifth barrel section 321 and the sixth barrel section 322 , and is in the shape of a conical barrel extending in the longitudinal direction and with a diameter gradually increasing from top to bottom.

Optionally, the cooling material 3141 may be made of a polymer material that does not produce harmful substances when degraded at high temperatures, such as polylactic acid and polyester. The filter material 3142 may be made of a material that can filter out harmful components in the aerosol, such as polyester, acetate fiber, cotton, and the like.

The connection relationship and working principle between the microwave heating component and the aerosol generating product component 3 of the present application are described in detail below with reference to FIG. 2 and FIG. 8 :

As shown in FIG. 2 , when the aerosol generating product assembly 3 is mounted on the microwave heating assembly, the entire aerosol generating product assembly 3 is rotatably disposed on the outer conductor unit 11 in the circumferential direction (the aerosol generating product assembly 3 is relatively fixed to the outer conductor unit 11 in the axial direction), and the plurality of aerosol generating products 33 can rotate relative to the outer conductor unit 11 and/or the inner conductor unit 13 around the central axis of the outer conductor unit 11, the base 312 on the aerosol generating product assembly 3 abuts against the top end surface of the dielectric unit 12, and part of the convex ridge 214 on the rotating unit 2 is inserted into part of the first engaging groove 3134 on the receiving section 313. The antenna action portion 1321b of the inner conductor unit 13 is closely attached to the inner circumferential wall surface of the bearing section 311 so as to be as close to the receiving groove 3113 as possible to ensure the heating effect, and a gap is left between the top end of the antenna action portion 1321b and the cooling material 3141 to prevent the antenna action portion 1321b from hindering the rotation of the aerosol generating product assembly 3.

As shown in FIG8 , by rotating the rotating cylinder 21, the multiple ridges 214 of the rotating cylinder 21 are meshed and transmitted with the multiple first engaging grooves 3134 on the receiving section 313, thereby driving the entire multiple aerosol generating products 33 to rotate, thereby changing the relative position relationship between the aerosol generating products 33 and the antenna action portion 1321b.

At the same time, by arranging the relative positions of the plurality of second engaging grooves 221 and the plurality of receiving grooves 3113 to correspond one to one in the circumferential direction, when the plurality of positioning protrusions 231 of the positioning part 23 simultaneously fall into the corresponding second engaging grooves 221, the antenna action portion 1321b is just opposite to one of the receiving grooves 3113 (, so that the antenna action portion 1321b can be completely opposite to the aerosol generating product 33, thereby ensuring the heating effect of the aerosol generating product 33.

In summary, the aerosol generating device of the present application realizes rotating segmented heating through the cooperation between the aerosol generating product assembly 3 and the rotating unit 2 and the inner conductor unit 13. Compared with the traditional aerosol generating device (heating the cylindrical aerosol generating product 33), the aerosol generating device of the present application can selectively heat the sheet-shaped aerosol generating product 33. Since the volume of the aerosol generating product 33 is reduced, the heating effect can fully act on the entire selected aerosol generating product 33, and the aerosol generating product 33 can be completely heated and atomized in a relatively short time, overcoming the technical defects of being unable to heat the aerosol generating product 33 uniformly and heating slowly.

Secondly, the aerosol generating device of the present application can also ensure the consistency of taste during the same puffing round of the user. (Since the multiple sheet-shaped aerosol generating products 33 are separated in different containing grooves 3113, only one of the aerosol generating products 33 is heated when the user puffs once. When the user puffs once and then turns to the next aerosol generating product 33 in the same round, the taste of the next puff can be ensured to be consistent.)

Furthermore, aerosol generating products 33 of different flavors can be loaded on the aerosol generating product assembly 3, so that users can switch flavors conveniently, omitting the insertion and extraction steps when replacing the aerosol generating product 33, thereby improving the user experience.

It can be understood that the above embodiments only express the preferred implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the patent scope of the present invention. It should be pointed out that, for ordinary technicians in this field, without departing from the concept of the present invention, the above technical features can be freely combined, and several deformations and improvements can be made, which all belong to the protection scope of the present invention. Therefore, all equivalent changes and modifications made to the scope of the claims of the present invention should belong to the scope covered by the claims of the present invention.
