The terms "inner", "outer", "left", "right" and the like as used herein are for illustrative purposes only and do not represent the only embodiments.

Referring to fig. 1 and 4, an electronic roasting apparatus 10 according to an embodiment of the present invention includes an extractor 100 and a heater 200, the electronic roasting apparatus 10 is used for heating an aerosol-generating substrate 20 to atomize and form smoke, and the aerosol-generating substrate 20 may be solid material such as tobacco.

Referring also to figures 1 to 4, in some embodiments the heater 200 comprises a power supply assembly 210, a heating element 220 and a sleeve 230, the heating element 220 being provided on the power supply assembly 210, the power supply assembly 210 being capable of energising the heating element 220 so that the heating element 220 generates heat, the heat generated by the heating element 220 being capable of atomising the aerosol-generating substrate 20 to form an aerosol, which may be drawn by a user.

The second free end 221 of the heating element 220 is relatively sharp so that the heating element 220 is able to pierce the aerosol-generating substrate 20, thereby enabling a portion of the heating element 220 to be wrapped in the aerosol-generating substrate 20 so that heat generated by the heating element 220 is more evenly and rapidly transferred to portions of the aerosol-generating substrate 20.

Referring to fig. 1 to 5, in some embodiments, the extractor 100 is provided with a first guiding structure 104, the sleeve 230 is provided with a second guiding structure 201, the second guiding structure 201 may be a protruding strip 231, the protruding strip 231 is provided on an inner surface of the sleeve 230, and the protruding strip 231 may be linear, that is, the protruding strip 231 extends along an axial direction of the sleeve 230, and the protruding strip 231 protrudes a set length along a radial direction of the sleeve 230 relative to the inner surface of the sleeve 230. When the second guiding structure 201 is a protruding strip 231, the first guiding structure 104 is a groove 132. In other embodiments, the second guiding structure 201 may be a groove 132, and in this case, the first guiding structure 104 is a rib 231.

Referring to fig. 2, 6 and 7, in some embodiments, extractor 100 includes a housing 101 and a toasting member 130, the toasting member 130 being disposed within the interior of housing 101. An annular gap 102 is formed between the housing 101 and the toasting member 130, and the sleeve 230 is capable of engaging the annular gap 102. Specifically, the housing 101 includes an inner shell 120 and an outer shell 110, the inner shell 120, the outer shell 110 and the roasting piece 130 are all substantially cylindrical, the inner shell 120 is connected between the outer shell 110 and the roasting piece 130, the cylindrical portions of the outer shell 110, the inner shell 120 and the roasting piece 130 are arranged in sequence from outside to inside, and the annular gap 102 is located between the inner shell 120 and the roasting piece 130.

Referring to figures 3 and 4, 6 and 7, in some embodiments the grilling component 130 comprises a base plate 136 and a side canister 135, the base plate 136 may be substantially circular, the side canister 135 may be cylindrical, the side canister 135 is connected to the periphery of the base plate 136, the base plate 136 and the side canister 135 together define a receiving cavity 134, the receiving cavity 134 may be configured to receive the aerosol-generating substrate 20, and the portion of the aerosol-generating substrate 20 exposed from the receiving cavity 134 is a suction area of a user. When the first guiding structure 104 is a groove 132, the groove 132 may be formed on the outer surface of the side cylinder 135, the groove 132 is linear and extends along the axial direction of the side cylinder 135, the groove 132 is recessed relative to the outer surface of the side cylinder 135 along the radial direction of the side cylinder 135 by a set depth, and the groove 132 is communicated with the annular gap 102. The bottom plate 136 is provided with a communication hole, which may be referred to as a first communication hole 131, the first communication hole 131 may be located at a central position of the bottom plate 136 and extend in an axial direction of the side tube 135, and the first communication hole 131 is communicated with the accommodating chamber 134. The bottom plate 136 has a bottom surface 133, and the bottom surface 133 is disposed adjacent to the power module 210, in other words, the bottom surface 133 faces the power module 210. The first through hole 131 has a strip-shaped opening 131a formed on the bottom surface 133, for example, the first through hole 131 may be a kidney-shaped hole, and the strip-shaped opening 131a is substantially racetrack-shaped. In other embodiments, the first guiding structure 104 may also be a groove 132 or a rib 231 disposed on the inner shell 120.

Referring to fig. 2 and 4, the elongated opening 131a of the first communication hole 131 formed on the bottom surface 133 has a smaller width and a larger length, and the heating member 220 has a larger width and a smaller thickness, and of course, the length of the elongated opening 131a is greater than the width of the heating member 220, the width of the elongated opening 131a is greater than the thickness of the heating member 220, and the width of the elongated opening 131a is smaller than the width of the heating member 220. Only when the width extending direction of the heating member 220 coincides with the length extending direction of the elongated opening 131a (in this case, the thickness extending direction of the heating member 220 is the same as the width extending direction of the elongated opening 131 a), the heating member 220 can be caused to enter the elongated opening 131a to be inserted through the first communication hole 131.

In the conventional installation process of the extractor 100 and the power supply module 210, since no guiding structure such as the protruding strip 231 and the groove 132 is provided, when the installation orientation of the extractor 100 relative to the power supply module 210 changes, the width extending direction of the heating element 220 is the same as the width extending direction of the elongated opening 131a, at this time, the width of the heating element 220 is greater than the width of the elongated opening 131a, and the heating element 220 cannot pass through the elongated opening 131a, so that the heating element 220 cannot be inserted into the first connecting hole 131. This mounting method thus requires repeated adjustment so that the width extension direction of the heating member 220 is the same as the length extension direction of the elongated opening 131a, which may reduce the assembly efficiency and even cause damage to the heating member 220 and the extractor 100 due to the forcible assembly.

Through the mutual cooperation of the protruding strip 231 on the sleeve 230 and the groove 132 on the baking element 130, in the process of fixing the extractor 100 on the power supply assembly 210, when the sleeve 230 is inserted into the annular gap 102 between the inner casing 120 and the baking element 130, the protruding strip 231 and the groove 132 can form a good guide in cooperation, so as to quickly prompt the installation direction of the extractor 100 to be adjusted in place, namely, only when the protruding strip 231 and the groove 132 are in cooperation, the width extension direction of the heating element 220 can be overlapped with the length extension direction of the elongated opening 131a, and finally, the heating element 220 is ensured to be quickly and accurately inserted into the first connecting hole 131, and the assembly efficiency and the assembly precision are improved. Meanwhile, in the process of debugging the installation orientation of the extractor 100 so that the protruding strips 231 are fitted with the grooves 132, since the heating member 220 is completely located in the sleeve 230, the sleeve 230 can prevent the heating member 220 from colliding with other components and being damaged.

In some embodiments, the number of the grooves 132 may be two, and in this case, the number of the ribs 231 on the sleeve 230 is also two. The grooves 132 penetrate the edge portion of the bottom surface 133, thereby forming through openings 132a on the bottom surface 133, the two through openings 132a being symmetrically disposed about the central axis of the elongated opening 131 a. The connecting line 103 between the two through openings 132a bisects the elongated opening 131a, i.e. the connecting line 103 divides the elongated opening 131a into two equal parts. Through the arrangement, the convenience of processing of the extractor 100 is facilitated, and the manufacturing cost of the extractor 100 is reduced. Meanwhile, by arranging the two grooves 132, the guiding precision is further improved, the baking part 130 is prevented from shaking in the matching process with the sleeve 230, and the heating part 220 is ensured to be smoothly inserted into the first communication hole 131.

Referring to fig. 6 and 7, in some embodiments, the outer shell 110 is enclosed to form an open cavity, the top of the outer shell 110 is provided with a mounting hole 111 communicating with the outside and the open cavity, the inner shell 120 and the toasting element 130 are both located in the open cavity of the outer shell 110, the toasting element 130 may be located at the center of the open cavity, the upper opening of the receiving cavity 134 is opposite to the mounting hole 111, and the aerosol-generating substrate 20 may be inserted into the mounting hole 111 and received in the receiving cavity 134.

A first cavity 150 is formed between the outer shell 110 and the inner shell 120, and the first cavity 150 can be defined by the outer shell 110, the inner shell 120 and the roasting part 130. The second cavity 160 is formed between the inner casing 120 and the toasting member 130, when the extractor 100 is mounted on the heater 200, the second cavity 160 can be defined by the inner casing 120, the toasting member 130 and the power module 210, the annular gap 102 is a part of the second cavity 160, and the first through hole 131 communicates the second cavity 160 and the receiving cavity 134. The inner case 120 is provided with a second communication hole 121, the second communication hole 121 is disposed near the power module 210, the second communication hole 121 communicates the first chamber 150 and the second chamber 160, the sleeve 230 is further provided with a third communication hole 233, and the third communication hole 233 is further away from the power module 210 than the second communication hole 121; when the sleeve 230 is inserted into the annular gap 102, the sleeve 230 divides the second chamber 160 into two parts, a second outer chamber 161 disposed adjacent to the first chamber 150 and a second inner chamber 162 disposed adjacent to the housing chamber 134, and the second outer chamber 161 and the second inner chamber 162 are communicated through a third communication hole 233. The outer casing 110, the inner casing 120 and the sleeve 230 have an air inlet channel 140 at one end thereof adjacent to the power module 210, and the air inlet channel 140 communicates with the outside and the second chamber 160.

Because the air inlet channel 140 is disposed close to the power supply component 210, the path through which the external air flows into the accommodating cavity 134 (corresponding to the mouth of the user) is greatly reduced, so that the heat taken away by the external air from the whole extractor 100 is less, and thus the heating component 220 heats the aerosol-generating substrate 20 on the basis of making full use of the existing heat, thereby reducing the energy consumption of the heating component 220 and improving the energy saving performance of the electronic toaster 10. Simultaneously, the workload of the heating element 200 is reduced, and the service life of the heating element 200 is prolonged.

Meanwhile, referring to the direction indicated by the dotted arrow in fig. 6, after the pumping is finished, the external gas sequentially passes through the gas inlet channel 140, the second inner chamber 162, the third communicating hole 233, the second outer chamber 161 and the second communicating hole 121 and enters the first chamber 150, the external gas can fill the second inner chamber 162, the second outer chamber 161 and the first chamber 150, the heat conductivity of the gas is lower than that of the housing 101, so that the heat in the extractor 100 can be effectively prevented from being rapidly discharged to the atmosphere, the gas in the second inner chamber 162, the second outer chamber 161 and the first chamber 150 actually plays a role in heat preservation, and the heat loss in the extractor 100 is prevented, so that the heating element 220 can be heated by fully utilizing the existing heat, and the energy consumption of the heating element 220 can be reduced to improve the energy saving performance of the electronic baking apparatus 10.
