The heating module 1 provided in the embodiment of the present invention is intended for use in an electronic atomizer device equipped with an atomizer 2. When the electronic atomizer device is in operation, at least a portion of the aerosol generated by atomization by the atomizer 2 flows through the heating module 1 to the exhaust section 4.

As shown in FIG. 1a, the heating module 1 includes a holder 11 and a heating assembly 12. The holder 11 forms a cavity that is substantially sealed except for an intake hole 17 and an exhaust hole 18. The holder 11 is formed with a first passage 111, a second passage 112, and a connecting passage 113. As shown in FIG. 3, the connecting passage 113 starts from the intake hole 17. When the heating module 1 is mounted on the electronic atomization device, the intake hole 17 communicates with the exhaust port 21 of the atomizer 2, that is, one end of the connecting passage 113 communicates with the exhaust port 21 of the atomizer 2. The first end of the first passage 111 and the second passage 112 communicate with each other in a direction extending toward the other end of the connecting passage 113. The second end of the first passage 111 is connected to the second end of the second passage 112, and when the electronic atomizer is in operation, the aerosol flowing through the first passage 111 and the aerosol flowing through the second passage 112 are mixed, and the mixed aerosol flows out through the exhaust hole 18. The mixing region of the aerosol flowing through the first passage 111 and the aerosol flowing through the second passage 112 may be within the first passage 111 or within the second passage 112, and it is understood that in many cases, the aerosol is mixed at the junction of the first passage 111 and the second passage 112.

The heating module 1 is formed with a receiving cavity 121 for receiving the aerosol-generating matrix, and the first passage 111 passes through the receiving cavity 121. The heating assembly 12 is provided around the first passage 111, and the heating assembly 12 is provided outside the receiving cavity 121 and is used to heat the aerosol-generating matrix when the electronic atomizing device is in operation. In this embodiment, the aerosol-generating matrix received in the receiving cavity 121 is the seasoning material 31 in the seasoning part 3, and the seasoning material 31 in the seasoning part 3 can generate an active substance. That is, the receiving cavity 121 is for receiving the seasoning part 3, and the heating assembly 12 is for heating the seasoning material 31 in the seasoning part 3 to adjust the release amount of the seasoning material 31. Usually, the temperature adjustment range of the heating assembly 12 is 10°C to 380°C.

By the above installation, the heating module 1 provided by the embodiment of the present invention provides a branch airway, a heating area, and an aerosol mixing area, which are applied to the electronic atomization device. With the aerosol-generating matrix attached to the heating module 1, the aerosol-generating matrix (seasoning part 3) is heated by a part of the aerosol after atomization by the atomizer 2, so that the ratio of the effective substance released from the aerosol-generating matrix (seasoning part 3) is increased, and the aerosol-generating matrix (seasoning part 3) is heated by the heating module 1. Meanwhile, a part of the aerosol atomized by the atomizer 2 flows to the exhaust part 4 of the electronic atomization device through the first passage 111, and a part of the aerosol flows to the exhaust part 4 of the electronic atomization device through the second passage 112. By mixing the two parts of aerosol, the taste of the aerosol is further adjusted to obtain a more balanced flavor, and the user can feel more effective substances in the aerosol inhaled by the user, which can give the user a better usage experience.

1a and 1b, in some embodiments, the heating module 1 further includes a seal member 13 provided near the exhaust hole 18. In one embodiment, the first passage 111 and the second passage 112 are provided in parallel, the seal member 13 is provided at the second end of the first passage 111 and the second end of the second passage 112, and the seal member 13 is provided with a communication groove 131 that communicates the second end of the first passage 111 and the second end of the second passage 112. By providing the communication groove 131 in the seal member 13, communication between the second end of the first passage 111 and the second end of the second passage 112 is realized while realizing communication between the second end of the first passage 111 and the second end of the second passage 112, and sealing of the communication point between the second end of the first passage 111 and the second end of the second passage 112 is realized, and the amount of aerosol flowing through the first passage 111 and the second passage 112 is limited when the electronic atomization device is in operation. By adjusting the size of the communication groove 131, the amount of aerosol flowing through the first passage 111 and the second passage 112 can be adjusted, making it possible to adjust the taste of the aerosol.

Referring to FIG. 2, in another embodiment, the second passage 112 includes a main passage 1121 and a sub-passage 1122 provided at the end of the main passage 1121, the main passage 1121 is provided parallel to the first passage 111, the extension direction of the sub-passage 1122 is perpendicular to the extension direction of the main passage 1121, and the sub-passage 1122 communicates with the first passage 111 and communicates the second end of the first passage 111 with the second end of the second passage 112. The structural design of the second passage 112 can communicate the second end of the first passage 111 with the second end of the second passage 112, and when the heating module 1 is disposed in the electronic atomization device and the electronic atomization device is in operation, the aerosol flowing through the first passage 111 and the aerosol flowing through the second passage 112 are mixed, and the aerosol may be mixed in the first passage 111 or in the second passage 112, but this is not limited in the embodiment of the present invention.

Referring to Fig. 1a-1b, it can be seen that the metal tube 122 has a receiving cavity 121, which is formed by the internal space of the metal tube 122, and the receiving cavity 121 is used to receive the seasoning part 3. When the heating module 1 is installed in the electronic atomization device and in operation, the heating module 1 heats the seasoning part 3 to release the active substances of the seasoning part 3. The heating assembly 12 may be, but is not limited to, a flexible circuit board, a thick film, or a metallic heating sheet. In order to improve the heating efficiency of the heating assembly 12, the heating assembly 12 is attached to the outer surface of the metal tube 122.

Specifically, the heating assembly 12 may be a flexible circuit board (FPC) assembly arranged around the outer surface of the metal tube 122. The heating module 1 includes a plurality of heating assemblies 12 arranged at intervals along the outer wall of the metal tube 122, and the interval distance is designed according to the heating efficiency requirements of the actual product, and the size and heating efficiency of the plurality of heating assemblies 12 do not need to be the same. By using the heating assembly 12 to heat the seasoning part 3, the release amount of the active substance of the seasoning material 31 of the seasoning part 3 heated by this heating module 1 is increased, and the aerosol released from the seasoning material 31 has good before-and-after consistency in taste.

Specifically, the heating assembly 12 may be a thick film printed on the outer surface of the metal tube 122. In this case, the heating assembly 12 is essentially a single piece, thereby reducing the manufacturing and assembly process and reducing the manufacturing defect rate of the heating module 1.

As shown in Figs. 1a-1b, in some embodiments, the heating module 1 further includes an insulating part 14 disposed around the heating assembly 12 and disposed on the side of the heating assembly 12 away from the receiving cavity 121. There is a gap between the insulating part 14 and the heating assembly 12, thereby forming air insulation between the insulating part 14 and the heating assembly 12, further reducing the heat loss of the heating assembly 12 and improving the heating efficiency of the heating assembly 12.

In order to achieve a good thermal insulation effect, in some embodiments, the thermal insulation part 14 has an annular structure and is an integral structure, and the heating assembly 12 is completely disposed within a cavity formed by being surrounded by the thermal insulation part 14. The specific structures of the heating assembly 12 and the thermal insulation part 14 are designed as needed.

In some embodiments, the heating module 1 further comprises a fixing mechanism 16 for achieving fixation of the aerosol-generating matrix (seasoning component 3). In one embodiment, the fixing mechanism 16 is provided entirely or partially within the receiving cavity 121.

Referring to FIG. 3, the electronic atomizer includes a heating module 1, an atomizer 2, a seasoning part 3, an exhaust part 4, a battery 5, a controller 6, an airflow sensor 7, and a housing 8. The connection between the heating module 1 and the atomizer 2 may be a detachable connection such as a snap connection, or a non-detachable connection such as a holder 11 of the heating module 1 integrally molded with the housing 8 of the atomizer 2. Specifically, it is sufficient to design the air intake hole 17 of the connection passage 113 in the heating module 1 and the exhaust port 21 of the atomizer 2 to be in communication with each other as necessary. In an embodiment of the present invention, the seasoning part 3 is a part containing an active substance, that is, the seasoning material 31 in the seasoning part 3 contains an active substance, where the active substance may be a nicotine flavoring or a pharmaceutical ingredient, or other active substance, but the embodiment of the present invention is not limited thereto.

The housing 8 forms a storage cavity 80, and the storage cavity 80 formed by the housing 8 is provided with the heating module 1, the atomizer 2, the seasoning part 3, the battery 5, the controller 6, and the airflow sensor 7. The atomizer 2 is for atomizing the matrix to be atomized to generate an aerosol, and the atomizer 2 includes an atomization chamber (not shown) and an exhaust port 21 communicating with the atomization chamber, and the aerosol atomized by the atomizer 2 flows out from the exhaust port 21.

The user inhales the aerosol through the exhaust part 4. The exhaust section 4 and the housing 8 may be formed integrally, or may be fixed together with an adhesive or the like.

In one embodiment, the heating module 1, the atomizer 2 and the battery 5 are arranged side by side, the seasoning part 3 is provided in the receiving cavity 121 in the heating module 1, and the exhaust part 4 is provided in the downstream direction of the heating module 1. Optionally, the second passage 112 is provided on the side of the first passage 111 farther from the atomizer 2. The specific installation position of the airflow sensor 7 may be designed according to needs, and it can be understood that the airflow sensor 7 only needs to be able to sense the change in airflow during the suction process.

The exhaust section 4 and the exhaust port 21 are connected via the connecting passage 113, the first passage 111, and the second passage 112. That is, the aerosol generated by the atomizer 2 passes through the connecting passage 113, then branches into the first passage 111 and the second passage 112 and reaches the exhaust section 4. It is understood that the aerosol generated by the atomizer 2 passes through at least one of the first passage 111 and the second passage 112 to reach the exhaust section 4. It is understood that the heating module 1 may further be provided with an adjustment component for adjusting the amount of aerosol flowing through the first passage 111 and the second passage 112.

In one embodiment, the seasoning part 3 is provided in the first passage 111.

The first part of the aerosol and the second part of the aerosol are mixed before flowing out of the exhaust part 4, thereby achieving the blending of the flavors of the aerosol.

In one embodiment, the exhaust port 21 of the atomizer 2 is provided at one end of the side wall of the atomizer 2 far from the exhaust section 4, and the intake port of the atomizer 2 is provided at one end close to the exhaust section 4 of the atomizer 2. Since the intake ports of the first passage 111 and the second passage 112 are located at one end far from the exhaust section 4, by providing the exhaust port 21 of the atomizer 2 at one end of the side wall of the atomizer 2 far from the exhaust section 4, the path through which the aerosol atomized by the atomizer 2 enters the first passage 111 and the second passage 112 can be shortened, the generation of condensation can be reduced, the amount of aerosol at the exhaust section 4 can be increased, and the user experience can be improved.

In one embodiment, an aerosol mixing region 15 is formed between the seasoning part 3 and the exhaust part 4, and the aerosol of the first part in the first passage 111 and the aerosol of the second part in the second passage 112 are mixed in the aerosol mixing region 15 and then enter the exhaust part 4. That is, the aerosol in the first passage 111 and the aerosol in the second passage 112 are mixed outside the seasoning part 3, and the mixed aerosol enters the exhaust part 4 and is inhaled by the user.

The exhaust unit 4 is not essential in an electronic atomizer. When the seasoning part 3 is provided with a suction nozzle part, the suction nozzle part of the seasoning part 3 functions as the exhaust unit 4, and in particular, in another electronic atomizer shown in FIG. 4, the aerosol mixing area 15 is located in the suction nozzle part of the seasoning part 3.

The controller 6 is electrically connected to the heating assembly 12, and the controller 6 controls the heating temperature of the heating assembly 12 to adjust the amount of aroma release of the seasoning material 31 so that the aroma concentration of the seasoning material 31 in the aerosol in the exhaust section 4 is maintained uniform with the continuous operation of the atomizer 2. In one embodiment, the controller 6 controls the heating temperature of the heating assembly 12 based on the number of puffs detected by the airflow sensor 7. In another embodiment, the controller 6 controls the heating temperature of the heating assembly 12 based on the amount of aerosol in the first passage 111 and the second passage 112. It is understood that the controller 6 controls the heating temperature of the heating assembly 12 by integrating multiple conditions.

In an embodiment of the present invention, by providing a first passage 111 and a second passage 112, a portion of the aerosol atomized by the atomizer 2 passes through the seasoning part 3 in the first passage 111 and reaches the aerosol mixing area 15, and a portion of the aerosol passes through the second passage 112 and reaches the aerosol mixing area 15.
