[0040] The present invention improves the stability of the substrate to be heated by fixing it inside the microwave cavity 6, and prevents the substrate from being displaced due to vibration, which affects the uniformity and utilization of heating, thereby improving the heating effect and user experience.

[0041] Specifically, one end of the cover plate 18 is rotatably connected to the microwave cavity 6, and the other end oppositely arranged is freely arranged. During the buckling process, the cover plate 18 presses the substrate to be heated toward the inside of the microwave cavity 6, so that the end away from the opening 19 contacts the inner wall of the microwave cavity 6, so that the substrate to be heated is clamped and fixed between the inner wall of the microwave cavity 6 and the cover plate 18 after the cover plate 18 is buckled. The cover plate 18 is rotatably connected to the microwave cavity 6 via the rotating shaft 4.

[0042] Preferably, the cover plate 18 is connected to the microwave cavity 6 via a self-locking hinge, so that the cover plate 18 automatically snaps in place after being rotated to a certain angle.

[0043] Embodiment 2

[0044] like Figure 1As shown, the difference between this embodiment and the first embodiment is that the substrate to be heated is protruded from the outer peripheral wall of the opening 19 to form the hand-held portion 5, and a first sealing ring with an annular protrusion is provided on the side of the cover plate 18 close to the opening 19. When the cover plate 18 is buckled, the axis of the first sealing ring is parallel to the axis of the opening 19, and the first sealing ring is axially sleeved to the outside of the hand-held portion 5, and the end face is in contact with the outer peripheral wall of the opening 19.

[0045] The microwave cavity 6 is in the shape of a straight cylinder with a horizontally extending axis, and one end is open to form an opening 19. The cross-section of the first sealing ring is annular, and the outer diameter of the first sealing ring is larger than the diameter of the opening 19, so that when the cover plate 18 is buckled, the end face of the first sealing ring fits against the outer peripheral wall of the opening 19.

[0046] After the first sealing ring is sleeved onto the outside of the hand-held part 5 , it contacts the hand-held part 5 , so that the hand-held part 5 is radially fixed inside the first sealing ring.

[0047] The cross section of the handle 5 is circular, and the inner diameter of the first sealing ring is greater than or equal to the diameter of the handle 5 , so that when the cover plate 18 is buckled, the first sealing ring is axially sleeved to the outside of the handle 5 .

[0048] Among them, Figure 3 As shown, the substrate to be heated is a cigarette cartridge 17, which includes a substrate portion 13 that can form smoke, and at least one side of the substrate portion 13 is provided with a hand-holding portion 5 for a user to hold.

[0049] The present invention provides a hand-held portion 5 so that the user can take the cigarette cartridge 17 through the hand-held portion 5, thereby avoiding deformation of the matrix portion 13 caused by the user holding the matrix portion 13 of the cigarette cartridge 17 and matrix 13 residue on the hand, thereby making the delivery of the cigarette cartridge 17 more hygienic and reliable.

[0050] The handheld portion 5 is cylindrical, and the matrix portion 13 is a columnar shape coaxial with the handheld portion 5 and of equal diameter, and is fixedly connected to the handheld portion 5. The matrix portion 13 and the handheld portion 5 can be fixedly connected after being butted together by gluing, or can be fixedly connected after being butted together by winding and covering.

[0051] The hand-held part 5 is made of plastic.

[0052] The handheld portion 5 has a porous structure, so that airflow passes through the handheld portion 5 from the pores of the porous structure. A hollow flow channel is provided in the handheld portion 5, and the openings at both ends of the flow channel are respectively provided at both ends of the handheld portion 5, so that airflow passes through the handheld portion 5 from the flow channel.

[0053] The microwave cavity 6 is in the shape of a straight cylinder with a horizontally extending axis, and one end of the microwave cavity 6 is open to form an opening 19. The axial length of the microwave cavity 6 is smaller than the axial length of the cigarette cartridge 17, so that after the user axially inserts the cigarette cartridge 17 from the opening 19 into the interior of the microwave cavity 6 through the cigarette cartridge 17 hand-held portion 5, the end of the matrix portion 13 away from the hand-held portion 5 contacts the bottom wall of the microwave cavity 6, and the hand-held portion 5 protrudes from the outer peripheral wall surface of the opening 19; preferably, the inner diameter of the microwave cavity 6 is equal to the diameter of the cigarette cartridge 17, so that after the cigarette cartridge 17 is inserted into the microwave cavity 6, the outer wall surface of the matrix portion 13 contacts the inner wall surface of the microwave cavity 6.

[0054] Embodiment 3

[0055] like Figure 1 As shown, the difference between this embodiment and embodiments 1 and 2 is that a second sealing ring with an annular protrusion is provided on one side of the cover plate 18 close to the opening 19. When the cover plate 18 is buckled, the axis of the second sealing ring is parallel to the axis of the opening 19, and it is buckled into the interior of the microwave cavity 6 from the opening 19, and axially sleeved to the outside of the substrate to be heated, and its outer wall is matched with the inner wall of the microwave cavity 6.

[0056] The microwave cavity 6 is in the shape of a straight cylinder with its axis extending horizontally, and one end is open to form an opening 19. The cross-section of the second sealing ring is circular, and the outer diameter of the second sealing ring is equal to the diameter of the opening 19, so that when the cover plate 18 is buckled, the outer wall of the second sealing ring matches the inner wall of the microwave cavity 6.

[0057] After the second sealing ring is sleeved on the outside of the substrate to be heated, it contacts the substrate to be heated, so that the substrate to be heated is radially fixed inside the second sealing ring.

[0058] The cross section of the substrate to be heated is circular, and the inner diameter of the second sealing ring is set to be greater than or equal to the diameter of the substrate to be heated, so that when the cover plate 18 is buckled, the second sealing ring is axially sleeved to the outside of the substrate to be heated.

[0059] Embodiment 4

[0060] like Figure 1 As shown, the difference between this embodiment and embodiments 1 to 3 is that an output device 8 for outputting microwaves is provided in the microwave cavity 6, and the output device 8 includes a second antenna, and the second antenna surrounds the periphery of the substrate to heat the substrate.

[0061] The present invention surrounds the second antenna around the periphery of the matrix so that microwaves are gradually output from the outside of the matrix to the inside to penetrate the matrix. Compared with gradually outputting microwaves from one side of the matrix to the other side to penetrate the matrix, the arrangement of the present invention shortens the time from microwave output to penetration of the matrix, increases the heating speed of the matrix, and at the same time, improves the uniformity of heating the matrix, thereby enhancing the user experience.

[0062] The first end of the second antenna extends toward the second end in a spiral shape and surrounds the outer periphery of the substrate. The second antenna is in a cylindrical spiral shape.

[0063] The microwave cavity 6 is a straight cylinder with a horizontally extending axis, and the helical second antenna is coiled and fixed on the side wall surface of the microwave cavity 6. The outer diameter of the helical second antenna is equal to the inner diameter of the straight cylinder microwave cavity 6. After the second antenna is axially inserted into the microwave cavity 6, the outer side surface is pressed against the side wall surface of the microwave cavity 6, so that the second antenna is coiled and fixed on the side wall surface of the microwave cavity 6.

[0064] The microwave cavity 6 is a straight cylinder with a horizontally extending axis. The second helical antenna is coiled and fixed on the side wall of the microwave cavity 6, with its inner side exposed in the microwave cavity 6 and its outer side embedded in the side wall of the microwave cavity 6. A groove for the second helical antenna to be embedded is provided on the side wall of the microwave cavity 6. While the first end of the second antenna extends toward the second end in a helical shape, the second antenna gradually embeds into the groove and cooperates with each other, so that the second antenna is coiled and fixed on the side wall of the microwave cavity 6. The first end of the second antenna passes through the microwave cavity 6 and is connected to the microwave generator 3 for generating microwaves, which is arranged outside the microwave cavity 6. The helical height of the second antenna is greater than or equal to the length corresponding to the substrate, so that the second antenna surrounds the entire substrate to optimize the heating effect. The helical height is the length in the axial direction. The axis of the opening 19 coincides with the axis of the second helical antenna, and the opening 19 is perpendicular to the second antenna and is arranged facing the second end of the second antenna.

[0065] The microwave cavity 6 is provided with an exhaust port for exhausting air and an air inlet 20 for taking in air.

[0066] The first end of the microwave cavity 6 door body 5 is rotatably connected to the microwave cavity 6, and the second end is locked and connected to the microwave cavity 6 via a lock; a cover opening structure 7 for opening the lock is provided on the outer wall of the microwave cavity 6, and the cover opening structure 7 is a button.

[0067] Embodiment 5

[0068] The difference between this embodiment and the first to fourth embodiments is that the output device 8 includes a first antenna, and the first antenna is embedded in the substrate to heat the substrate.

[0069] The present invention embeds the first antenna into the substrate to be heated so that microwaves are gradually output from the inside of the substrate to the outside to penetrate the substrate. Compared with gradually outputting microwaves from one side of the substrate to the other side to penetrate the substrate, the arrangement of the present invention shortens the time from microwave output to penetration of the substrate, increases the heating speed of the substrate, and at the same time, increases the uniformity of heating of the substrate, thereby improving the user experience.

[0070] The first antenna and the second antenna may be disposed in the microwave cavity 6 separately, or may be disposed in the microwave cavity 6 at the same time.

[0071] The first end of the first antenna extends straight to the second end, and the first antenna is gradually buried in the matrix from the second end. The first antenna is needle-shaped, and its tip is the second end. The microwave cavity 6 is a straight cylinder with a horizontally extending axis, and the first antenna is arranged on the axis of the microwave cavity 6. The first antenna is axially inserted into the microwave cavity 6, and its first end is fixed to the bottom wall of the microwave cavity 6, and the second end is freely arranged, so that the first antenna is gradually buried in the matrix from the second end.

[0072] The first end of the first antenna passes through the microwave cavity 6 and is connected to the microwave generator 3 for generating microwaves, which is arranged outside the microwave cavity 6. The embeddable length of the first antenna is greater than or equal to the length corresponding to the substrate, so that the first antenna passes through the substrate to optimize the heating effect. The embeddable length is the length embedded in or buried through the substrate. The axis of the opening 19 coincides with the axis of the first antenna, and the opening 19 is perpendicular to the first antenna and is arranged facing the second end of the first antenna.

[0075] The present invention achieves storage of smoke-forming substrates by arranging a microwave cavity 6 inside the shell, so that one electronic cigarette is equivalent to the amount of several packs of ordinary cigarettes, which is easy to carry and beautiful in appearance; the present invention also arranges a heating module inside the shell so that the substrate is heated inside the shell to form smoke, avoiding open flames, thereby avoiding fire hazards, being safer, and also avoiding ash falling, which is more hygienic. The present invention improves heating speed and uniformity by adopting microwave heating, thereby improving user experience and utilization of the substrate.

The cavity wall of at least one side of the microwave cavity 6 is formed by a shell. The opening 19 is provided on the cavity wall of the microwave cavity 6 formed by the shell. The cover plate 18 is provided corresponding to the opening 19.

[0078] Embodiment 7

[0079] like Figure 1 As shown, the difference between this embodiment and the first to sixth embodiments is that one end of the smoke channel 9 is an air outlet, which is connected to the outer space of the housing through a filter 14 for filtering smoke; the other end is an air inlet 20, which passes through the microwave cavity 6 and is connected to the outer space of the housing, and the smoke channel 9 and the microwave cavity 6 are mutually connected. The air inlet 20 of the smoke channel 9 is provided on the cover plate 18. The air inlet 20 and the air outlet of the smoke channel 9 are directly connected.

[0080] The present invention allows the smoke channel 9 to pass through the microwave cavity 6 and be connected with the microwave cavity 6, so that the smoke in the microwave cavity 6 is directly discharged from the shell from the outlet of the smoke channel 9, thereby increasing the density of the smoke and improving the user experience.

The heating module further includes a battery 16 connected to the microwave generator 3 via a connecting circuit for providing power, and the control device is a switch 2 provided on the connecting circuit for controlling the connection circuit to be on and off.

[0083] When the sensor 10 in the smoke channel 9 senses the change in airflow, the battery 16 supplies power to the microwave generator 3 , and the microwave generator 3 starts to work to heat the substrate in the microwave cavity 6 .

[0084] Preferably, the sensor 10 is arranged downstream of the connection between the smoke channel 9 and the microwave cavity 6 .

[0090] The present invention provides a support portion 22 so that the user can take the filter 14 through the support portion 22, thereby avoiding deformation of the filter portion 21 caused by the user holding the filter portion 21 of the filter 14, thereby avoiding the problem that the filter portion 21 cannot seal the flue outlet, thereby making the use of the filter 14 more reliable. At the same time, the present invention also reduces the use of filter materials by providing the support portion 22, thereby reducing production costs.

[0091] The support portion 22 has a porous structure, so that airflow passes through the support portion 22 from the pores of the porous structure; a hollow flow channel is provided in the support portion 22, and openings at both ends of the flow channel are respectively provided at both ends of the support portion 22, so that airflow passes through the support portion 22 from the flow channel.

[0092] The support part 22 is columnar, and the filter parts 21 at both ends of the support part 22 are columnar with the same axis and the same diameter as the support part 22, and are fixedly connected to the support part 22; the support part 22 is made of plastic.

[0093] like Figure 1 As shown, a filter cavity 11 for installing a filter tip 14 is provided at the air outlet of the smoke channel 9. The filter cavity 11 is in the shape of a straight cylinder with a horizontally extending axis, one end of which is connected to the smoke outlet, and the other end oppositely arranged is open to form an installation port. The axial length of the filter cavity 11 is smaller than the axial length of the filter tip 14, and the inner diameter is equal to the diameter of the filter tip 14. After the filter tip 14 is axially sleeved from the installation port into the interior of the filter cavity 11, one end of the filter portion 21 on one side away from the support portion 22 is in conflict with the bottom wall of the filter cavity 11, and the outer wall surface is in contact with the inner wall surface of the filter cavity 11, and the other side filter portion 21 oppositely arranged is protruded from the outer peripheral wall surface of the installation port for the user to inhale.

[0094] The filter chamber 11 is provided with a filter chamber door 15 for closing the installation port, so that the filter chamber door 15 can be closed when the electronic cigarette is not in use.
