[0028] The embodiment of the present application discloses a heating-not-burning device, which is used to heat an aerosol generating substrate 8 so that the aerosol generating substrate 8 generates an aerosol for use by a user.

[0029] For the heating-without-burning device disclosed in the embodiments of this application, please refer to Figures 1 to 3 , including an apparatus body, a rotating electrode 5 and an elastic member 6, the apparatus body including an atomizing tube 3 and a circuit board 4 spaced apart from the atomizing tube 3, the atomizing tube 3 having an atomizing channel 33 for inserting an aerosol generating matrix 8, and an opening 321 communicating with the atomizing channel 33 is provided on the wall of the atomizing tube 3; the rotating electrode 5 can be rotatably assembled on the apparatus body, the rotating electrode 5 is penetrated through the opening 321, the rotating electrode 5 has a triggering section 51 located in the atomizing channel 33 and a connecting section 53 extending outward from the wall of the atomizing tube 3, the triggering section 51 is configured to be inserted into the atomizing channel 33 as the aerosol generating matrix 8 is inserted, so as to drive the entire rotating electrode 5 to rotate; the elastic member 6 connects the apparatus body and the rotating electrode 5, and the elastic member 6 can exert an elastic force on the rotating electrode 5 to keep the connecting section 53 away from the circuit board 4.

[0030] The heating-not-burning device has an on state and a off state. In the on state, the trigger section 51 is located between the aerosol generating substrate 8 and the wall of the atomizing tube 3, and the connecting section 53 is electrically connected to the circuit board 4. In the off state, the trigger section 51 is suspended in the atomizing channel 33, and the connecting section 53 is spaced apart from the circuit board 4 under the action of the elastic member 6. In this way, the aerosol generating substrate 8 can be inserted into the atomizing channel 33, so that the aerosol generating substrate 8 drives the trigger section 51 to drive the entire rotating electrode 5 to rotate to the position where the connecting section 53 is connected to the circuit board 4. , so as to realize automatic opening of the heat-not-burning appliance; the aerosol generating matrix 8 can also be pulled out, so that the rotating electrode 5 can be rotated to the position where the connecting section 53 is separated from the circuit board 4 under the elastic action of the elastic member 6, so as to realize automatic closing of the heat-not-burning appliance. In this way, the heat-not-burning appliance can be automatically opened and closed with the insertion and removal of the aerosol generating matrix 8, which can avoid setting an exposed switch button on the heat-not-burning appliance, avoid the heat-not-burning appliance from being accidentally triggered and causing dry burning, and help to ensure and extend the service life of the entire heat-not-burning appliance.

[0031] For some examples, please refer to Figures 1 to 3 In the heating non-burning device, the device body includes a shell 1 and a frame 2 installed in the shell 1, the atomizer tube 3 and the circuit board 4 are fixedly installed on the frame 2, such as the atomizer tube 3 can be clamped on the frame 2 by a buckle 31, and the circuit board 4 can be installed on the frame 2 by an interference fit; the shell 1 has an air inlet and an air outlet 11, the atomizer tube 3 includes a cylinder 32, and the channel formed by the cylinder 32 is the atomization channel 33, the atomization channel 33 connects the air inlet and the air outlet 11, the aerosol generating matrix 8 can be inserted into the atomization channel 33 from the air outlet 11, the inner side wall of the cylinder 32 is provided with a protruding part, and the aerosol generating matrix 8 can be clamped by the protruding part to realize the fixation of the position of the aerosol generating matrix 8 in the atomization channel 33; the opening 321 is provided on the cylinder wall of the cylinder 32 to facilitate the communication between the opening 321 and the atomization channel 33.

[0032] The rotating electrode 5 can be a long strip plate-shaped electrode, and the extending direction of the rotating electrode 5 is perpendicular to the extending direction of its rotating axis. The rotating electrode 5 can be rotatably mounted on the device body, such as the frame 2 or the atomizing tube 3. The portion of the rotating electrode 5 in its extending direction passes through the opening 321 on the wall of the tube body 32, so that the rotating electrode 5 has a portion extending into the atomizing channel 33 and another portion located outside the atomizing channel 33.

[0033] In one embodiment, please refer to Figure 2 and Figure 4The rotating electrode 5 is rotatably assembled on the atomizing tube 3 through the rotating shaft 54. The rotating shaft 54 ​​is located outside the atomizing tube 3 and close to the edge of the opening 321. This can avoid affecting the extension length of the rotating electrode 5 into the atomizing channel 33 due to the installation position accuracy of the atomizing tube 3 or the rotating electrode 5 in the shell 1, which helps to ensure that the rotating electrode 5 is driven to rotate by the aerosol generating matrix 8 inserted into the atomizing channel 33; and the rotating shaft 54 ​​is close to the edge of the opening 321. This can meet the rotation stroke of the rotating electrode 5 under the condition of a smaller opening 321, which helps to reduce the amount of aerosol overflowing from the opening 321, thereby ensuring the user experience of the heating without burning appliance.

[0034] Of course, in other embodiments, the rotating electrode 5 and the atomizing tube 3 have better positioning accuracy in the outer shell 1, and the rotating electrode 5 can also be rotatably assembled on the skeleton 2 through the rotating shaft 54, as long as the rotating electrode 5 has a part extending into the atomizing channel 33 and another part located outside the atomizing channel 33.

[0035] Further, in one embodiment, please refer to Figures 2 to 4 The atomizing tube 3 also includes a mounting portion 34, which is connected to the outer wall of the barrel 32, and the rotating shaft 54 ​​is mounted on the mounting portion 34, so as to avoid affecting the structural strength of the barrel 32 due to the mounting hole or mounting groove set on the barrel 32. Of course, under the condition that the structural strength of the barrel 32 meets the use requirements, the mounting hole or mounting groove for the rotating shaft 54 ​​to pass through can also be set on the outer wall of the barrel 32, so as to reduce the material consumption of the atomizing tube 3 and reduce the cost.

[0036] In the embodiment where the rotating shaft 54 ​​is rotatably mounted on the mounting portion 34, please continue to refer to Figure 4 The mounting portion 34 includes mounting plates 341 arranged on both sides of the opening 321 in the axial direction of the barrel 32, and the mounting plates 341 are arranged in the extension direction of the barrel 32. Each mounting plate 341 is provided with a slot 342, and the slot of the slot 342 faces the air outlet 11 of the atomizing channel 33. The rotating shaft 54 ​​has a snap-fit ​​section that cooperates with the slot 342, and the outer diameter of the snap-fit ​​section is smaller than the size of the slot of the slot 342. In this way, the rotating shaft 54 ​​can be restricted from escaping from the slot 342 by the slot 342 having a smaller slot, that is, the rotating electrode 5 is restricted from separating from the atomizing barrel 3.

[0037] Of course, in other embodiments, a through hole may be provided on the mounting plate 341, and the rotating shaft 54 ​​may be located in the through hole, and the rotating shaft 54 ​​may be interference fit with the through hole to limit the rotating shaft 54 ​​from escaping from the through hole, that is, to limit the rotating electrode 5 from separating from the atomizing tube 3.

[0038] In some embodiments, the rotating electrode 5 has a trigger segment 51 located in the atomization channel 33, and the trigger segment 51 can be suspended in the atomization channel 33 when the heating non-combustion appliance is in a closed state. The trigger segment 51 can extend toward the central axis of the atomization channel 33, and under the limiting effect of the elastic member 6 on the rotating electrode 5, the trigger segment 51 can be kept in a suspended state; the length dimension and extension direction of the trigger segment 51 need to satisfy that the minimum distance between the trigger segment 51 and the central axis of the atomization channel 33 is less than the radius of the aerosol generating substrate 8, so that the trigger segment 51 can contact the aerosol generating substrate 8 inserted into the atomization channel 33, and during the insertion process of the aerosol generating substrate 8, the trigger segment 51 can be driven by the aerosol generating substrate 8 to rotate in the direction away from the air outlet 11 until it is pressed between the aerosol generating substrate 8 and the channel wall of the atomization channel 33.

[0039] The rotating electrode 5 also has a connecting section 53 extending outward from the wall of the atomizing tube 3. The connecting section 53 is located on the side of the wall of the atomizing tube 3 facing away from the atomizing channel 33 in the radial direction of the atomizing tube 3. In one embodiment, please refer to Figure 2 and Figure 3 The trigger section 51 and the connecting section 53 are arranged on both sides of the opening 321 on the wall of the atomizing tube 3 in the radial direction of the atomizing tube 3, and the trigger section 51 and the connecting section 53 can be respectively arranged at both ends of the length direction of the rotating electrode 5, which helps to reduce the size of the entire rotating electrode 5; the trigger section 51 and the connecting section 53 are connected through the middle section 52, the extension direction of the trigger section 51 and the extension direction of the middle section 52 have an angle, the extension direction of the connecting section 53 can be perpendicular to the extension direction of the trigger section 51, the trigger section 51, the connecting section 53 and the middle section 52 can respectively correspond to the two waist sides and the upper base side of the isosceles trapezoid; when the heating without burning appliance is in a closed state, the trigger section 51 can form an overhanging section suspended in the atomizing channel 33.

[0040] When the heating without burning appliance is in a closed state, the connecting section 53 can be separated from the circuit board 4 under the elastic action of the elastic member 6 to ensure that the rotating electrode 5 is insulated from the circuit board 4; the connecting section 53 can also rotate around the rotating axis 54 with the trigger section 51 to a position electrically connected to the circuit board 4 during the automatic opening process of the heating without burning appliance to ensure that the rotating electrode 5 is electrically connected to the circuit board 4.

[0041] Of course, in other embodiments, the rotating electrode 5 can also be arranged in a straight line or a wavy structure, and the trigger section 51 and the connecting section 53 are respectively located at the two ends of the rotating electrode 5; or it can also be located at a position close to the rotation axis of the rotating electrode 5, as long as the trigger section 51 can be inserted into the aerosol generating matrix 8 in the atomization channel 33 when the heating without burning appliance is in the closed state, and pressed between the outer peripheral surface of the aerosol generating matrix 8 and the channel wall of the atomization channel 33, and when the heating without burning appliance is in the open state, the connecting section 53 can be reliably electrically connected to the circuit board 4.

[0042] In one embodiment, please continue to refer to Figure 2 and Figure 3 It can be arranged that when the heating without burning appliance is in a closed state, the extension direction of the trigger segment 51 can be perpendicular to the extension direction of the atomization channel 33. In this way, on the premise that the trigger segment 51 can be pressed by the aerosol generating substrate 8 to between the outer peripheral surface of the aerosol generating substrate 8 and the channel wall of the atomization channel 33, it helps to reduce the length dimension of the trigger segment 51, that is, reduce the material consumption of the entire rotating electrode 5, and reduce the cost of the rotating electrode 5 and the entire heating without burning appliance.

[0043] Furthermore, it is also provided that when the heating without burning appliance is in the on state, the trigger section 51 is fitted with the outer peripheral surface of the aerosol generating matrix 8, so as to ensure that when the heating without burning appliance is switched from the off state to the on state, the angle of rotation of the rotating electrode 5 around its rotation axis is less than or equal to 90°. This can reduce the deformation requirements and size requirements of the elastic member 6 on the one hand, thereby helping to reduce costs; on the other hand, it can also help to reduce the size of the opening 321 on the wall of the atomizing tube 3, thereby reducing the amount of aerosol overflowing from the opening 321 to the outside of the atomizing channel 33.

[0044] Of course, in other embodiments, it can also be arranged that when the heating non-combustion appliance is in the closed state, the angle between the extension direction of the trigger segment 51 and the extension direction of the atomization channel 33 is less than 90°, as long as the trigger segment 51 can be pressed by the aerosol generating substrate 8 toward the space between the outer peripheral surface of the aerosol generating substrate 8 and the channel wall of the atomization channel 33 during the process of inserting the aerosol generating substrate 8 into the atomization channel 33.

[0045] For the elastic member 6, in one embodiment, please continue to refer to Figure 2 The elastic member 6 may include a cylindrical coil spring, one end of which is connected to the atomizing tube 3, and the other end of which is connected to the connecting section 53 of the rotating electrode 5. The cylindrical coil spring can apply an elastic driving force to the connecting section 53 to rotate the connecting section 53 away from the circuit board 4, so as to ensure that when the heat-not-burning appliance is in a closed state, the connecting section 53 and the circuit board 4 are spaced apart and insulated, thereby effectively preventing the heat-not-burning appliance from being accidentally triggered and causing dry burning.

[0046] Furthermore, a connecting section 53 is provided with a connecting surface and a contact surface which are arranged opposite to each other in the circumferential direction of the rotating electrode 5, the connecting surface is used to connect to the cylindrical coil spring, and the contact surface can be in contact with the circuit board 4 when the heating without burning appliance is in the turned-on state to ensure a reliable electrical connection between the rotating electrode 5 and the circuit board 4.

[0047] Of course, in other embodiments, the elastic member 6 may also include a torsion spring, which is located at the connection position between the rotating electrode 5 and the device body. In the embodiment in which the rotating electrode 5 is rotatably assembled on the atomizer tube 3, the torsion spring may act on the connection position between the atomizer tube 3 and the rotating electrode 5. The torsion spring may exert an elastic driving force on the rotating electrode 5 to rotate the connecting section 53 of the rotating electrode 5 in a direction away from the circuit board 4, so as to ensure that when the heat-not-burn device is in a closed state, the connecting section 53 and the circuit board 4 are spaced and insulated, which can effectively prevent the heat-not-burn device from being accidentally triggered and causing dry burning; in this way, only a contact surface facing the circuit board 4 in the rotation direction of the rotating electrode 5 can be arranged on the connecting section 53, so that when the heat-not-burn device is in an open state, the contact surface is in contact with the circuit board 4, thereby ensuring that the rotating electrode 5 and the circuit board 4 are reliably electrically connected.

[0048] The extending direction of the connecting section 53 on the rotating electrode 5 is perpendicular to the extending direction of the triggering section 51. Figure 2 and Figure 3 , it can be arranged that when the heating without burning appliance is in a closed state, the extension direction of the connecting section 53 is parallel to the extension direction of the atomizing channel 33, that is, the extension direction of the connecting section 53 is perpendicular to the extension direction of the triggering section 51, and the connecting surface on the connecting section 53 is arranged in the extension direction of the atomizing channel 33, and the connecting surface faces the atomizing tube 3. In this way, when the heating without burning appliance is in a closed state, the cylindrical coil spring is in a free state, which can facilitate the connection between the two ends of the cylindrical coil spring and the atomizing tube 3 and the connecting surface on the connecting section 53 respectively.

[0049] In one embodiment, please refer to Figure 2 and Figure 3 The circuit board 4 includes a main board 41 and a fixed electrode 42 fixed on the main board 41. The main board 41 is located outside the atomizer tube 3. The extension direction of the main board 41 is parallel to the extension direction of the atomizer channel 33. The extension direction of the fixed electrode 42 is perpendicular to the extension direction of the main board 41. The fixed electrode 42 is electrically connected to the main board 41, and the fixed electrode 42 is located at the end of the main board 41 in the extension direction of the main board 41, so that the installation and fixation of the fixed electrode 42 is convenient.

[0050] Furthermore, the rotation stroke of the rotating electrode 5 can be set to 90°. When the heating non-combustion appliance is in the open state, the extension direction of the connecting section 53 is perpendicular to the extension direction of the atomization channel 33. In this way, the contact surface on the connecting section 53 is perpendicular to the extension direction of the atomization channel 33, which facilitates the fitting of the connecting surface on the connecting section 53 and the fixed electrode 42 in the open state.

[0051] Of course, in other embodiments, the angle between the extension direction of the connecting section 53 on the rotating electrode 5 and the extension direction of the trigger section 51 can be set to be less than 90°, and the position of the fixed electrode 42 on the circuit board 4 can be set according to the extension direction of the connecting section 53 in the on state to ensure that the connecting surface on the connecting section 53 fits with the fixed electrode 42 in the on state, thereby ensuring the reliability of the electrical connection between the rotating electrode 5 and the fixed electrode 42 in the on state.

[0052] Or in other embodiments, the rotation stroke of the rotating electrode 5 can also be less than 90° or greater than 90°, and the angle between the extension direction of the connecting section 53 and the extension direction of the trigger section 51 can be ignored. The circuit board 4 is set to include only the main board 41, and the main board 41 is provided with a solder point for electrically connecting to the connecting section 53 of the rotating electrode 5. As long as the heating non-combustion appliance is in the turned-on state, the connecting section 53 can be electrically connected to the solder point on the circuit board 4.

[0053] In order to ensure that the rotating electrode 5 is reliably connected to the circuit board 4 when the heating without burning device is in the turned-on state, in some embodiments, please refer to Figure 2 and Figure 3 The heating without burning appliance may also include an electromagnet 7, which is mounted on the appliance body and electrically connected to the circuit board 4; when the heating without burning appliance is in an on state, the electromagnet 7 is energized, the electromagnet 7 can generate magnetism due to the energization, and the electromagnet 7 can magnetically absorb the connecting section 53 to keep the connecting section 53 in conductive contact with the circuit board 4; when the heating without burning appliance is in a off state, the electromagnet 7 is de-energized, and the connecting section 53 is released after the electromagnet 7 loses its magnetism, so that the connecting section 53 can be away from the circuit board 4 under the elastic driving action of the elastic member 6.

[0054] It should be noted that, in these embodiments, it is necessary to ensure that the connecting section 53 of the rotating electrode 5 has magnetism, that is, the connecting section 53 can be made of magnetic material, or the connecting section 53 is coated with an adsorption layer made of magnetic material.

[0055] In an embodiment in which a fixed electrode 42 electrically connected to a connecting section 53 is fixedly mounted on a circuit board 4, an electromagnet 7 may be supported and fixed on the fixed electrode 42. The fixed electrode 42 has a contact mating surface facing the connecting section 53, and also has a mounting surface for mounting the electromagnet 7. The contact mating surface is configured to be able to fit with the contact surface on the connecting section 53 to achieve electrical connection between the fixed electrode 42 and the rotating electrode 5. The mounting surface and the contact mating surface are arranged relative to each other to ensure that the electromagnet 7 is located on the side of the fixed electrode 42 that is away from the connecting section 53. In this way, after the connecting section 53 is in conductive contact with the fixed electrode 42, the electromagnet 7 may be energized to magnetically adsorb the connecting section 53 so that the connecting section 53 and the fixed electrode 42 are in reliable contact.

[0056] Of course, after the heating without burning device finishes working and stops heating, the electromagnet 7 can be powered off, such as after the heating without burning device has been heated for a certain period of time, or after the heating without burning device has reached the maximum number of puffs. At this time, the electromagnet 7 releases its adsorption effect on the connecting section 53, and after the aerosol generating matrix 8 is pulled out of the atomization channel 33, under the action of the elastic member 6, the connecting section 53 is away from the fixed electrode 42 to close the heating without burning device.

[0057] Of course, in other embodiments, the electromagnet 7 can also be arranged to be fixed on other parts of the appliance body, such as on the frame 2. When the heating without burning appliance is in the turned-on state, the electromagnet 7 is energized and the connecting section 53 is magnetically attracted to ensure that the connecting section 53 is in reliable conductive contact with the fixed electrode 42 or the circuit board 4.

[0058] The above specific examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. For those skilled in the art of the present invention, some simple deductions, deformations or substitutions can be made based on the idea of ​​the present invention.
