Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Through the long-term research of the inventor of the application, if a mode that a plurality of heating wires are connected in parallel is adopted as the heating structure of the electronic cigarette, the heating structure is complex, the electric connection mode is complex, the wiring arrangement of the heating structure is inconvenient, the number of the heating wires can be increased only for improving the heating power and the efficiency, and the cost is high. In order to improve the above technical problem, the present application proposes at least the following embodiments.

Referring to fig. 1, the electronic cigarette of the present application includes a smoking set 1 and a cartridge 2. The smoking article 1 can be coupled to the cartridge 2. The cartridge 2 may have stored or carried therein material to be heated. The smoking article 1 is used to heat a material to be heated within the cartridge 2 to produce smoke. The smoking article 1 and cartridge 2 may be integral. The smoking article 1 and cartridge 2 may also be removable so that the e-cigarette may replace the cartridge 2. The smoking article 1 can be matched to different cartridges 2.

Referring to fig. 2, the smoking set 1 of the present embodiment may include a battery assembly 10, a heating module 20 and a fixing cover 30. The battery pack 10 is used to supply power for the heat generation of the heat generating module 20 or may supply power for the operation of the entire electronic cigarette. The heat generating module 20 is connected to the battery assembly 10. For example, the heat generating module 20 may be fixed to one end of the battery assembly 10. The fixing cover 30 may be used to cover the heat generating module 20 and cooperate with the heat generating module 20.

As shown in fig. 2, the battery assembly 10 may include a battery case 11, a battery 12 disposed in the battery case 11, and a charging port 13 disposed in the battery case 11 and coupled to the battery 12. The battery 12 may be a built-in battery 12, i.e. the battery 12 is built-in the battery case 11. The battery 12 may also be detachably disposed in the battery housing 11, for example, the battery housing 11 has a battery compartment opening (not shown), through which the battery 12 is placed into the battery compartment of the battery housing 11, or through which the battery 12 is removed from the battery compartment. Of course, the battery 12 may be an external battery 12 disposed outside the battery case 11. The battery 12 may be charged by connecting an external power source through the charging port 13, or the battery 12 may charge an external device through the charging port 13. In this embodiment, the charging port 13 may have a data transmission function in addition to the charging function, so as to facilitate data transmission between the electronic cigarette and an external device. The heat generating module 20 can be fixed at one end of the battery housing 11 and electrically coupled to the battery 12, so that the battery 12 can provide electric energy for the heat generating module 20. The charging port 13 may be provided at the other end of the battery case 11.

The heat generating module 20 can generate heat by using the electric energy of the battery 12 to generate heat to heat the material to be heated. Referring to fig. 3, an exemplary structure of the heat generating module 20 according to the present embodiment is described as follows.

The heat generating module 20 may include a fixing base 21, a heat generating member 22, a buffer member 23, and a glue portion 24. Under the action of the battery 12, the heating member 12 converts the electric energy into heat energy to heat the material to be heated. The fixing base 21 may be used to fix the heat generating member 22, and the heat generating member 22 is fixed to one end of the battery assembly 10, for example, one end of the battery case 11, through the fixing base 21. The buffer member 23 is used for providing a buffer function when the heat generating member 22 is fixed to the fixing base 21. The glue part 24 may fix the heat generating member 22 and the fixing base 21 to each other.

As shown in fig. 3, the fixing base 21 is formed with a receiving cavity 211. An opening 212 communicating with the accommodating cavity 211 is formed at one end of the fixing base 21, and the opposite end may be a bottom wall of the fixing base. At least a portion of the bottom wall of the fixing base may serve as the bottom wall of the accommodating cavity 211. The heating element 22 is accommodated in the accommodating cavity 211, for example, one end of the heating element 22 is fixed to the bottom wall of the accommodating cavity 211, and the other end extends toward the opening 212. The bottom wall of the fixing base 21 extends away from the opening 212 to form a fixing portion 213, and the fixing portion 213 can be fixed to the battery assembly 10. As shown in fig. 3, a locking groove 2130 may be formed on the outward side of the fixing portion 213, and the fixing portion 213 may be inserted into one end of the battery case 11. As shown in fig. 2, a locking block 110 is provided to protrude from the inside of the battery case 11. The locking piece 110 enters the locking groove 2130 to be matched with each other. The engagement between the locking block 110 and the locking groove 2130 can limit the movement of the fixing base 21 in a direction away from the battery case 11, and thus the fixing base 21 can be stably fixed to one end of the battery case 11.

Referring to fig. 4, the heat generating member 22 may include a substrate 221 and one or more alloy heat generating sheets 222. The alloy heating sheet 222 may be disposed on one side of the substrate 221 or the other side opposite to the substrate. For example, the alloy heat generating sheet 222 may be specifically disposed on one side surface or the other opposite side surface of the substrate 221. The number of the alloy heating sheets 222 may be two, and the two alloy heating sheets are respectively disposed on two opposite sides of the substrate 221. The substrate 221 may be a substrate 221 made of an insulating material such as ceramic. The ceramic material is, for example, a porous ceramic material. The opposite side surfaces of the substrate 221 may be opposite side surfaces in the thickness direction thereof.

The alloy heating plate 222 may be made of the same predetermined alloy material. The predetermined alloy material may use at least one of a platinum alloy material, a silver-palladium alloy material, a silver alloy material, and a nickel alloy material. Of course, the alloy heat generating sheet 222 may be made of other alloy materials with low resistivity. In this embodiment, the alloy slurry of the same formula corresponding to the predetermined alloy material is formed on one side of the substrate 221 through a one-step forming process. The one-step forming process may include a plurality of process flows, and may refer to a one-step complete manufacturing process, for example, the one-step forming process includes at least a printing process and a sintering process, or a casting process and a sintering process. For example, a predetermined alloy paste is printed and sintered on one side of the substrate 221 to form an alloy heat generating sheet 222 on one side of the substrate 221, such that the material of the alloy heat generating sheet 222 is uniform or substantially uniform. For example, a groove is formed in the side surface of the substrate 221, and the same predetermined alloy slurry is poured into the groove, followed by a solidification process such as sintering, to form the alloy heat generating sheet 222.

Optionally, the sheet resistance of the alloy heating sheet 222 is 5-60m Ω. Optionally, the sheet resistance of the alloy heating sheet 222 is 10-50m Ω. Optionally, the sheet resistance of the alloy heating sheet 222 is 20-30m Ω. The sheet resistance can be adjusted by adjusting the thickness of the alloy heating sheet 222, or by using alloy materials with different resistivities.

By forming the same preset alloy material on the two side surfaces which are arranged back to back in one-step forming process, compared with the prior art that a plurality of different materials are used and the forming process is performed for a plurality of times, the process can be simplified, the cost is reduced, the process control is improved, the influence of repeated processes on the substrate 221 is reduced, and the stability of the substrate 221 is ensured.

As shown in fig. 4, the alloy heat generating sheet 222 includes a heating section 2221 and conductive sections 2222 connected to both ends of the heating section 2221. Heating segment 2221 and conductive segment 2222 may be of uniform material, and heating segment 2221 and conductive segment 2222 may each be a thick film circuit made of the same alloy material. Both ends of the heating section 2221 are connected to the conductive sections 2222, and the alloy heating sheet 222 includes two conductive sections 2222, which are respectively connected to both ends of the heating section 2221. Conductive segment 2222 is connected to both ends of heating segment 2221 to form a series configuration of heating lines.

The inventor of the application carries out a comparative test in research, and the comparative manufacturing process is as follows: the heating section 2221 and the conductive section 2222 are formed on the substrate 221 by using a heating paste and a conductive paste, respectively, and the formulations of the heating paste and the conductive paste are different, and the sheet resistances of the heating section 2221 and the conductive section 2222 formed by the heating section 2221 and the conductive section 2222 are also different. Specifically, in forming the heating section 2221, it is formed on the substrate 221 through one printing, sintering, or the like using the corresponding heating paste. And, in forming conductive segment 2222, it is formed on substrate 221 through one printing, sintering, etc. using a corresponding conductive paste. When the partial area of conductive segment 2222 is also used for soldering, a soldering segment is formed on substrate 221 by printing, sintering, etc. with a soldering paste. That is, the above comparison process requires at least two molding processes, i.e., at least two printing and sintering processes, which increases the number of processes of manufacturing the heat generating member 22, and repeated sintering may adversely affect the substrate 221, which may cause the substrate 221 to be easily cracked or even broken, and easily cause the alloy heat generating sheet 222 to fall off.

The manufacturing process of the embodiment is as follows: the heating section 2221 and the conducting section 2222 are formed on the substrate 221 by adopting the same preset alloy slurry through a one-step forming process, that is, the heating section 2221 and the conducting section 2222 can be formed on the substrate 221 by the alloy slurry with the same formula through one-step forming processes such as printing, sintering and the like, so that the alloy heating sheet 222 with consistent sheet resistance or approximately consistent sheet resistance is formed, thus the manufacturing process flow of the heating piece 221 for manufacturing the electronic cigarette can be reduced, the sintering times on the substrate 221 are reduced, the quality and the performance of the substrate 221 can be ensured, and the problems of fracture, resistance falling and the like caused by repeated sintering of the substrate 221 can be avoided.

In the present embodiment, the thickness of the alloy heat generating sheet 222 may refer to the thickness of the alloy heat generating sheet 222 in the thickness direction of the substrate 221. The length of the alloy heat generating sheet 222 may refer to an extending distance from one conductive segment 2222 to another conductive segment 2222 after passing through one end of the heating segment 2221 and the other end of the heating segment 2221, and is equal to the sum of the extending length of the heating segment 2221 and the extending lengths of the two conductive segments 2222. In the present embodiment, conductive segment 2222 has a length that is less than the length of heating segment 2221. That is, the length of conductive segment 2222 is less than the length of heating segment 2221. Optionally, the sum of the lengths of conductive segments 2222 connected across heating segment 2221 is less than the length of heating segment 2221. Conductive segment 2222 has a width H2 that is greater than a width H1 of heating segment 2221.

By setting the length of the conductive segment 2222 of the alloy heating sheet 22 to be smaller than the length of the heating segment 2221, and the width H2 of the conductive segment 2222 to be larger than the width H1 of the heating segment 2221, the heating resistance of the alloy heating sheet 222 can be effectively increased, the non-heating resistance of the alloy heating sheet 222 can be reduced, and the heating efficiency and the conversion efficiency of the alloy heating sheet 222 in the series structure can be effectively improved.

Heating segment 2221 may have a length that is 20-40 times the length of conductive segment 2222. Optionally, heating segment 2221 has a length that is 28-35 times, optionally 30-33 times, the length of conductive segment 2222. Heating segment 2221 may have a width that is 0.1-0.3 times the width of conductive segment 2222. Alternatively, heating segment 2221 may have a width that is 0.2 times the width of conducting segment 2222. After long-term experiments of the inventor, the length ratio and the width ratio of the heating section 2221 and the conducting section 2222 are obtained, so that the effective heating resistance and the heating efficiency of the alloy heating sheet 222 in the series structure can be effectively ensured. The effective conversion efficiency of the alloy heat generating sheet 222 is described below by way of example:

it is assumed that the thickness of the alloy heat generating sheet 222 is h, i.e. the thicknesses of the conductive segment 2222 and the heating segment 2221 are both h. L1 is the length of heating segment 2221, D1 is the width of heating segment 2221, L2 is the length of conductive segment 2222, D2 is the width of conductive segment 2222, R1 is the resistance (i.e., heating resistance) of heating segment 2221, R2 is the resistance (i.e., non-heating resistance) of conductive segment 2222, ρ is the resistivity of the predetermined alloy material, and K is the efficiency of electrical energy conversion from electrical energy to thermal energy of heating segment 2221. Namely:

wherein the content of the first and second substances,

then it can be calculated that:

order to

Where k1 is the ratio of the length of heating segment 2221 to the length of conductive segment 2222, and k2 is the ratio of the width of heating segment 2221 to the width of conductive segment 2222.

Then it can be further calculated that:

if the width of heating segment 2221 is 0.1 times the width of conducting segment 2222 (i.e., k2 equals 0.1), the length of heating segment 2221 is 40 times the length of conducting segment 2222 (i.e., k1 equals 40); finally, K is calculated to be approximately equal to 99.75 percent. It can be seen that the method has higher electric energy conversion efficiency.

So that the formula can be utilized

The ratio of the length of heating segment 2221 to the length of conductive segment 2222 and the ratio of the width of heating segment 2221 to the width of conductive segment 2222 are flexibly adjusted. For example, when the electric energy conversion efficiency K is required to be ensured to be more than 99%, the formula can be used

It is deduced that K > 99%, and K2 ≦ 0.2 if K1 has a value of 20 (i.e., the length of heated segment 2221 is 20 times the length of conductive segment 2222), and K1 ≦ 20. That is, when the length of heating section 2221 is 20 times the length of conducting section 2222, the width of heating section 2221 may be adjusted such that the width of heating section 2221 is 0.2 times or 0.1 times or any multiple between 0.2 and less than 0.1 times the width of conducting section 2222, and thus, the electrical energy conversion efficiency K > 99% may be ensured.

To optimize the routing space on the substrate 221, the conductive segment 2222 may be disposed at one end of the substrate 221, one end of the conductive segment 2222 is connected to the heating segment 2221, the other end away from the heating segment 2221 may be used as a free end, and the free end of the conductive segment 2222 extends to the edge of one end of the substrate 221. That is, the conductive segment 2222 is located at one side of the substrate 221 and adjacent to one end of the substrate 221, one end of the conductive segment 2222 is connected to the heating segment 2221, and the other end of the conductive segment 2222, which is not connected to the heating segment 2221, is used as a free end and extends to the edge of the one end of the substrate 221, so as to facilitate subsequent electrical connection by the conductive segment 2222. Conductive segment 2222 coupled to one end of heating segment 2221 and conductive segment 2222 coupled to the other end of heating segment 2221 may be disposed parallel to each other and disposed adjacent to each other. Of course, two conductive segments 2222 may be inclined or angled with respect to each other. The heating section 2221 is bent between its two ends, and may be bent several times. Specifically, the parallel portions may be connected by a bent portion to form a bent heating section 2221. The parallel portions of heating segment 2221 may be parallel to conductive segment 2222.

The free end of the conductive segment 2222 is extended to the edge of one end of the substrate 221, so that the conductive segment 2222 can be conveniently welded to be electrically connected to the battery 12, and the two ends of the heating segment 2221 are bent, the structure of the alloy heating sheet 222 can be further optimized, the wiring space of the substrate 221 is further optimized, and the length and the width of the wiring are flexibly set.

Referring to fig. 5, in order to achieve the adjustability of the heating temperature, the alloy heat generating sheet 222 may further include an auxiliary heating section 2223 and a switching circuit m. The switching circuit m is used to control the auxiliary heating section 2223 to be disconnected or connected. Two ends of the auxiliary heating section 2223 may be connected to the two conductive sections 2222, respectively. The auxiliary heating section 2223 and the heating section 2221 are connected in parallel. The switching circuit m controls the auxiliary heating section 2223 to be turned on or off, so that the heating circuit of the alloy heating sheet 222 can be changed. After the switching circuit m controls the auxiliary heating section 2223 to be turned on, the auxiliary heating section 2223 and the heating section 2221 are connected in parallel, so that the equivalent heating resistance becomes small, and thus the heating power of the alloy heating sheet 222 can be reduced. After the switching circuit m controls the auxiliary heating section 2223 to be turned off, the heating section 2221 generates heat, and the auxiliary heating section 2223 does not actively generate heat by passing current, so that the heating temperature of the alloy heating sheet 222 can be controlled. The switch circuit m is, for example, a switch. The battery case 11 may be provided with a switch button, such as a push type, a sliding type, or a touch type switch button, for controlling the switch circuit m to be turned off or turned on, so that a user can control the heating efficiency of the electronic cigarette to adapt to different use scenarios. For example, the heating temperature required for different materials to be heated is different, so that the heating efficiency and temperature of the electronic cigarette can be adjusted by the auxiliary heating section 2223 and the switching circuit m.

As shown in fig. 4 and 5, conductive segment 2222 may be divided into a conductive sub-segment 2222a and a connecting sub-segment 2222 b. Conductive subsection 2222a is connected between heating section 2221 and connecting subsection 2222 b. The connector section 2222b may be used to connect a lead to electrically couple the battery 12 via the lead. In particular, connector sub-segment 2222b is located at a free end of conductive segment 2222, and a pad 2223 may be provided. The pads 2223 may be used for soldering with a wire, thereby electrically connecting the battery 12 through the wire, so that the battery 12 can supply power to the alloy heat generating sheet 222. The present embodiment may exemplarily divide the substrate 221 into a heating section 221a, a conductive section 221b, and a connection section 221 c. Heating segment 2221 is located in heating segment 221a, conductive segment 2222a is located in conductive segment 221b, and connecting segment 2222b is located in connecting segment 221 c.

Referring to fig. 6 and 7 in combination with fig. 3, one end of the substrate 221 provided with the conductive segment 2222 is at least partially inserted into the bottom wall of the accommodating cavity 211, and the heating segment 2221 is located in the accommodating cavity 211. That is, the conductive section 221b and the connection section 221c are partially inserted into the bottom of the receiving cavity 211, and the heating section 2221 may be exposed in the receiving cavity 211. Of course, the partially conductive section 221b may also be exposed in the receiving cavity 211.

The bottom wall of the accommodating cavity 211 is provided with a first section hole 213 communicated with the accommodating cavity 211. The first section hole 213 may also directly communicate with the accommodating cavity 211, or may communicate with the accommodating cavity 211 through other holes. The region of one end of the substrate 221 where the conductive subsection 2222a is located (i.e., the conductive section 221b) is at least partially located within the first section aperture 213. The buffer 23 is sleeved on the outer periphery of a region (i.e., the conductive section 221b) where the conductive segment 2222a is disposed at one end of the substrate 221, and abuts against the surface of the first section hole 213. That is, the conductive section 221b of the substrate 221 is at least partially disposed in the first section of hole 213, and the buffer 23 is disposed around the conductive section 221b and abuts between the outer circumference of the conductive section 221b and the surface of the first section of hole 213. The buffer member 23 is, for example, a soft silicone member.

By arranging the buffer member 23 between the outer periphery of the conductive section 221b and the first section hole 213, a buffer effect can be provided for the electronic cigarette when the electronic cigarette falls or collides, and damage to the alloy heating plate 222 caused by vibration generated by the fall or collision can be reduced.

In order to improve the structural stability of the buffer member 23 and further provide a more stable buffering effect, a protrusion 23a is protruded from one end of the buffer member 23 away from the receiving cavity 211 in a direction away from the substrate 221. The bottom wall of the receiving cavity 211 is formed with a corresponding step surface 214 at an end position of the first section hole 213 away from the receiving cavity 211, and the protruding portion 23a abuts against the step surface 214 to limit the movement of the buffer member 23 toward the receiving cavity 211. That is, the end of the buffer member 23 far away from the accommodating cavity 211 can be located outside the first section hole 213, and through the cooperation of the protruding portion 23a and the step surface 214, the structural stability of the bottom walls of the buffer member 23 and the accommodating cavity 211 can be enhanced, so that when the electronic cigarette is collided or falls, the buffer member 23 can be kept in a stable state to reduce the falling phenomenon, and further, a more stable buffering effect can be provided.

As shown in fig. 6, the bottom wall of the accommodating cavity 211 is opened with a second section of hole 215 connected to the first section of hole 213 and penetrating through the outer surface of the bottom wall. The outer surface of the bottom wall is a surface of a side facing away from the opening 212 of the holder 21. The sizes of the first and second segment holes 213 and 215 may refer to the sizes of the first and second segment holes 213 and 215 as widths in a cross section taken perpendicular to the plane of the substrate 221. Optionally, the second stage aperture 215 is sized larger than the first stage aperture 213 to form a step surface 214 at the location where the first stage aperture 213 and the second stage aperture 215 are joined. Since the second-stage hole 215 is larger in size than the first-stage hole 213, a step surface 214 may be formed at a portion of the connection position of the first-stage hole 213 and the second-stage hole 215 except for a communication portion with the first-stage hole 213, so that the protrusion 23a of the buffer member 23 can be engaged with the step surface 214.

The glue portion 24 may be coated on the outer periphery of the region where the connection section 2222b2 is disposed on the base plate 221. That is, the glue portion 24 can be coated on the connecting section 221c of the substrate 221. When one end of the base plate 221 is inserted into the bottom wall of the receiving cavity 211, the connecting section 221c of the base plate 221 may be located in the second section of the hole 215. The connecting section 221c may be located entirely within the second bore 215 or may extend partially beyond the second bore 215 and out the outer surface of the bottom wall.

Specifically, when one end of the base plate 221 is inserted into the bottom wall of the accommodating cavity 211, the glue is dripped into the second section hole 215 from the outer surface of the bottom wall to coat the connecting section 221c of the base plate 221, and finally the glue portion 24 is formed after solidification. In the present embodiment, the glue portion 24 may be an AB glue, a one-component heat-curable glue, a UV glue, or the like.

In order to further improve the fixing effect of the substrate 221 and the structural stability of the buffer 23, the following structure may be further provided: an accommodating groove 24a is formed at an end of the glue portion 24 remote from the outer surface of the bottom wall. If dripping from the outer surface of the bottom wall into the second-stage hole 215 is utilized, the receiving groove 24a surrounding the boss 23a can be formed. The accommodation groove 24a indicated in fig. 7 is occupied by the projection 23a, and therefore, its position is indicated as an overlapping position of the projection 23a and the like. As shown in fig. 6, a portion of the stepped surface 214 formed at the connection position of the first-stage hole 213 and the second-stage hole 215 is engaged with the protrusion 23a, and another portion is adjacent to the protrusion 23a, so that the portion of the stepped surface 214 adjacent to the protrusion 23a may be recessed to form the fixing groove 216. The fixing groove 216 communicates with the second stage hole 215 and is spaced apart from the first stage hole 213. The periphery 24b of the water seal portion 24, which surrounds the receiving groove 24a, is inserted into the fixing groove 216, and the protrusion 23a of the buffer member 23 is located in the receiving groove 24 a.

Periphery 24b that establishes into holding tank 24a through enclosing of glue portion 24 cooperates with fixed slot 216 for glue portion 24 can be more firm with the fixed between the diapire of holding chamber 211, and then can improve the structural stability of alloy heating sheet 222 and the diapire of holding chamber 211, holding tank 24a can cladding bolster 23's bellying 23a, can further improve bolster 23's structural stability, and then can improve its stability that provides the cushion effect, can fall or when colliding at the electron cigarette, improve the protective capacities to the electron cigarette.

Of course, the glue portion 24 may be provided with a lead hole (not labeled), and the lead hole may provide one end of a lead wire to be electrically connected to the battery 12, and the other end of the lead wire penetrates into the second section hole 215 to be connected to the conductive section 2222a of the connection section 221c, so as to enable the battery 12 to be electrically connected to the conductive section 2222 a.

As shown in fig. 1 and 2, when one end portion of the base plate 221 is inserted into the bottom wall of the accommodating cavity 211, the heating section 221 is exposed in the accommodating cavity 211, so that the heating section 2221 can be heated by the power supplied by the battery 12. Specifically, the stationary cover 30 may have an inner cavity 32 and an outer cavity 31. The outer chamber 31 is formed with an outer chamber 31a, and the inner chamber 32 is formed with a heat generating chamber 32 a. The inner chamber 32 is disposed in the outer chamber 31a of the outer chamber 31 and spaced apart from the wall of the outer chamber 31. The outer cavity 31 has an insertion opening formed on the side facing the battery case 11, and the inner cavity 32 has a through hole formed on the side facing the battery case 11. When the fixing cover 30 is covered on the fixing base 21, the side wall 213 of the accommodating cavity 211 surrounded by the fixing base 21 enters the outer cavity 31a through the insertion opening, the inner cavity 32 is inserted into the accommodating cavity 211 of the fixing base 21, and the other end of the base plate 221 away from the bottom wall of the accommodating cavity 211 enters the heating cavity 32a through the through hole, so that the heating section 2221 is exposed in the heating cavity 32 a.

In this embodiment, the fixing cover 30 may serve as an extractor of the electronic cigarette for extracting the cartridge 2 of the electronic cigarette, so that the electronic cigarette separates the cartridge 2 from the electronic cigarette when the electronic cigarette is not in use. One side of the fixed cover 30 covers the fixed seat 21, and the other side can be used for connecting the cartridge 2. For example, the top wall of the fixing cover 30 is provided with a matching hole which is communicated with the heating cavity 32a and penetrates through the bottom wall of the fixing cover 30, and when the cartridge 2 is connected with the fixing cover 30, at least one part of the cartridge 2 extends into the heating cavity 32a through the matching hole. The portion of the cartridge 2 extending into the heat generating cavity 32a may carry a material to be heated, such as tobacco shred or tobacco tar, which is heated by the heating section 2221 to generate smoke. As shown in fig. 5, the fixing cover 30 may further be provided with a dust plug 33 engaged with the heating cavity 32a of the fixing cover 30, the dust plug 33 can cover an opening formed at an end of the heating cavity 32a away from the base, and when the electronic cigarette is not used, the opening can be covered by the dust plug 33 to prevent foreign matters from entering the heating cavity 32 a.
