Description

Technical Field

[0001] This utility model relates to the field of aerosol generation technology, and in particular to an aerosol generating device. Background Technology

[0002] Heated non-combustible aerosol generation systems typically include an aerosol generating device and an aerosol generating article adapted to the aerosol generating device. The aerosol generating article is detachably inserted into the aerosol generating device and can release aerosols under the heating of the aerosol generating device.

[0003] With the development of technology, in order to prevent safety accidents such as dry burning, a detection device is usually added to the aerosol generating device to detect whether the aerosol generating product has been inserted, so that the aerosol generating device can be turned on for heating only after the aerosol generating product has been inserted.

[0004] Detection devices in related technologies include capacitive detection devices and microswitch detection devices, which can meet the detection requirements to a certain extent. However, capacitive detection devices require at least two detection points and have many limitations, making them less suitable for miniaturized devices. Microswitch detection devices, on the other hand, are difficult to implement in applications such as split-type aerosol generators due to the size limitations of the switch itself and the space requirements for mobility.

[0017] The magnetic field blocking assembly includes a first bracket and a magnetic field blocking component connected to the first bracket. The first bracket includes a mating part that is slidably disposed in the sliding hole.

[0018] When the aerosol generating article is inserted into the receiving space, the mating part can be pushed by the aerosol generating article, thereby driving the magnetic field blocking component to move from the first position to the second position.

[0023] In some embodiments, there are two guide grooves, which are located on both sides of the sliding hole, and the sliding hole is formed through the inner cylinder wall.

[0024] In some embodiments, the Hall sensor and the magnet are respectively disposed on two opposite radial sides of the receiving space, and the magnetic field blocking member is located on the same side of the receiving space as the Hall sensor or the magnet.

[0042] In the following description, specific details such as particular system structures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of the present invention. However, those skilled in the art will understand that the present invention can be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0043] The technical solution adopted by this utility model to solve its technical problem is:

[0044] Figure 1 and Figure 2 An aerosol generation system 100 according to some embodiments of the present invention is shown. The aerosol generation system 100 may include an aerosol generating device 1 and an aerosol generating article 2 matched with the aerosol generating device 1. In some embodiments, the aerosol generating device 1 may be longitudinally elongated columnar, having an axially extending columnar receiving space A (e.g., Figure 3 (as shown) and a socket 120 connecting the containment space A to the outside. The aerosol generating device 1 can heat the aerosol generating article 2 inserted into the containment space A through the socket 120 after being powered on, so as to release the aerosol extract in the aerosol generating article 2 in a non-combustible state.

[0045] For example Figure 2 As shown, in some embodiments, the aerosol generating article 2 may be cylindrical, and may include an aerosol generating matrix section 201 and a mouthpiece section 202 axially connected to the aerosol generating matrix section 201. The aerosol generating matrix section 201 may include solid materials in the form of strips, flakes, or granules made from the leaves and / or stems of plants (e.g., tobacco or tea), and aroma components may be further added to the solid material. The length and diameter of the aerosol generating matrix section 201 are respectively equivalent to the depth and diameter of the receiving space A, so that when the aerosol generating article 2 is inserted into the receiving space A, the mouthpiece section 202 is exposed outside the aerosol generating device 1, making it convenient for the user to inhale.

[0046] See also Figure 3 and Figure 4In some embodiments, the aerosol generating device 1 may include a housing 10 and a heating element 20, a detection element 30, a control element 40, and a power supply element 50 disposed within the housing 10. The heating element 20 defines the aforementioned receiving space A to heat the aerosol generating article 2 inserted into the receiving space A. The detection element 30 is used to detect whether the aerosol generating article 2 is inserted into the heating element 20. The control element 40 is electrically connected to the heating element 20, the detection element 30, and the power supply element 50, respectively, and is used to control the power supply element 50 to supply power to the heating element 20 when the detection element 30 detects that the aerosol generating article 2 is inserted into the receiving space A.

[0047] For example Figure 2 and Figure 3 As shown, in some embodiments, the housing 10 may be cylindrical, and may include a cylindrical housing body 11 with an opening at one end and a housing cover 12 covering the opening, on which the aforementioned insertion port 120 is formed. It is understood that the shape of the housing 10 is not limited to cylindrical, and other shapes such as elliptical cylinder, cuboid, and irregular shape may also be applicable.

[0048] like Figure 4 and Figure 5 As shown, in some embodiments, the heating element 20 may be longitudinally elongated, and may include a heating tube 21, an upper seat 22, and a lower seat 23. The heating tube 21 has a hollow structure, forming a heating space 210. The diameter of the heating space 210 matches the diameter of the aerosol generating matrix section 201, so that after the aerosol generating matrix section 201 is inserted into the heating space 210, the aerosol generating matrix section 201 and the heating tube 21 are tightly fitted together. The upper seat 22 is installed at the upper end of the heating tube 21, and the lower seat 23 is installed at the lower end of the heating tube 21. The outer diameters of the upper seat 22 and the lower seat 23 are adapted to the inner diameter of the shell body 11, so that when the heating element 20 is axially disposed in the shell body 11, the outer wall surfaces of the upper seat 22 and the lower seat 23 are in close contact with the inner wall surface of the shell body 11.

[0049] like Figure 6 , Figure 7 and Figure 8As shown, in some embodiments, the upper seat 22 may include an inner cylinder 221, a first mounting structure 222, a second mounting structure 223, a second support frame 224, and a flange 225. The first mounting structure 222 and the second mounting structure 223 are respectively disposed on opposite sides of the outer wall of the inner cylinder 221. The second support frame 224 is disposed on the first mounting structure 222, and the flange 225 is disposed at one end of the inner cylinder 221 near the insertion port 120. The dimensions between the first mounting structure 222 and the second mounting structure 223 are adapted to the diameter of the flange 225. The outer diameter of the flange 225 is larger than the outer diameter of the inner cylinder 221, and the outer diameter of the flange 225 is adapted to the inner diameter of the shell body 11, so that when the upper seat 22 is axially disposed within the shell body 11, the outer walls of the first mounting structure 222, the second mounting structure 223, the second support frame 224, and the flange 225 are in contact with the inner surface of the shell body 11. The inner cylinder 221, the first mounting structure 222, the second mounting structure 223, and the flange 225 are an integral structure. Of course, in other embodiments, the inner cylinder 221, the first mounting structure 222, the second mounting structure 223, and the flange 225 can also be connected by other suitable methods such as snap-fit ​​or splicing.

[0050] like Figure 8 and Figure 9 As shown, in some embodiments, the inner cylinder 221 has a cylindrical structure, and the cylindrical structure forms a central through hole 2210. The inner diameter of the inner cylinder 221 is adapted to the inner diameter of the heating space 210 so that the aerosol-generated article 2 can enter through the insertion port 120 and be inserted into the heating space 210 through the central through hole 2210. The central through hole 2210 and the heating space 210 axially form the aforementioned receiving space A. The two opposite outer walls of the inner cylinder 221 are provided with a sliding hole 2211 and a transfer hole 2212 through them in the axial direction.

[0051] For reference Figure 7 In some embodiments, the first mounting structure 222 may include a first mounting plate 2221 and a second mounting plate 2222 respectively mounted at intervals on the outer wall of the inner cylinder 221. The aforementioned sliding hole 2211 is formed on the outer wall of the inner cylinder 221 between the first mounting plate 2221 and the second mounting plate 2222.

[0052] A guide groove 22211, a first slot 22212, and a third slot 22213 are provided on the first mounting plate 2221. The first guide groove 22211 is obliquely through the side wall of the first mounting plate 2221 corresponding to the second mounting plate 2222, and the distance from its end near the insertion port 120 to the central axis of the receiving space A is less than the distance from its end away from the central through hole 2210 to the central axis of the receiving space A. The first slot 22212 and the third slot 22213 are respectively provided at the upper and lower ends of the side wall of the first mounting plate 2221 corresponding to the second mounting plate 2222.

[0053] The second mounting plate 2222 also has a guide groove 22211, a second slot 22222, and a fourth slot 22223. The two guide grooves 22211 are obliquely through-holes on the corresponding sidewalls of the second mounting plate 2222 and the first mounting plate 2221. The second slot 22222 and the fourth slot 22223 are respectively located at the top and bottom ends of the sidewall of the second mounting plate 2222 corresponding to the first mounting plate 2221. The two guide grooves 22211 correspond to each other, the first slot 22212 corresponds to the second slot 22222, and the third slot 22213 corresponds to the fourth slot 22223.

[0054] In some embodiments, the second mounting structure 223 is a frame structure. The frame structure of the second mounting structure 223 is not limited to square, circular, irregular or other shapes.

[0055] like Figure 7 and Figure 10 As shown, in some embodiments, the second bracket 224 may include a mounting portion 2241, an upper stop portion 2242, and a lower stop portion 2243. The width and height of the mounting portion 2241 are adapted to the width and height of the first mounting plate 2221 and the second mounting plate 2222, so that the mounting portion 2241 is fastened between the first mounting plate 2221 and the second mounting plate 2222 to cover the first mounting cavity 2220. The upper stop portion 2242 and the lower stop portion 2243 are respectively mounted on the side wall of the mounting portion 2241 near the receiving space A. The mounting portion 2241, the upper stop portion 2242, and the lower stop portion 2243 are an integral structure. Of course, in other embodiments, the mounting portion 2241, the upper stop portion 2242, and the lower stop portion 2243 may also be connected by other methods such as splicing, snap-fitting, or welding.

[0056] In some embodiments, the mounting portion 2241 has a mounting hole 22411. In some embodiments, the upper stop portion 2242 may include two first engaging portions 22421 respectively mounted on two opposite sides and two limiting slots 22422 formed in the upper stop portion 2242. The two first engaging portions 22421 are respectively engaged in the first slots 22212 and the second slots 22222 to fix the mounting portion 2241 between the first mounting plate 2221 and the second mounting plate 2222.

[0057] In some embodiments, the lower stop 2243 may include two second engaging portions 22431 respectively mounted on two opposite sides. The two second engaging portions 22431 are respectively engaged in the third slot 22213 and the fourth slot 22223 to fix the mounting portion 2241 between the first mounting plate 2221 and the second mounting plate 2222.

[0058] like Figure 6 and Figure 7As shown, in some embodiments, the detection component 30 may include a Hall sensor 31, a magnet 32, and a magnetic field blocking component 33. The Hall sensor 31 and the magnet 32 ​​are spaced apart, and the magnetic field blocking component 33 is movable between a first position and a second position. In the first position (see reference...), the magnetic field blocking component 33... Figure 12 The magnetic field blocking component 33 is positioned between the Hall sensor 31 and the magnet 32, and the magnetic field strength detected by the Hall sensor 31 is less than a threshold. In the second position (see reference...), the magnetic field blocking component 33... Figure 13 The barrier between magnet 32 ​​and Hall sensor 31 is removed, and the magnetic field strength detected by Hall sensor 31 is greater than or equal to a threshold. Hall sensor 31 is electrically connected to control component 40; and when the magnetic field strength detected by Hall sensor 31 is less than the threshold, control component 40 controls power supply component 50 to interrupt power supply to heating component 20, so that heating component 20 stops heating aerosol generating product 2 inserted into receiving space A. When the magnetic field strength detected by Hall sensor 31 is greater than or equal to the threshold, control component 40 controls power supply component 50 to supply power to heating component 20, and heating component 20 starts heating aerosol generating product 2 inserted into receiving space A.

[0059] For example, the magnetic field blocking component 33 is made of a high-permeability material (such as permalloy, with a permeability greater than or equal to 2000). When in the first position, it shields the magnetic field of the magnet 32 ​​through the magnetic field line concentration effect, making the magnetic field strength sensed by the Hall sensor 31 less than or equal to 5mT (threshold). The Hall sensor 31 outputs a low-level signal, and the control component 40 controls the power supply component 50 to interrupt the power supply to the heating component 20. When in the second position, the magnetic field lines penetrate directly to the Hall sensor 31, and the magnetic field strength is greater than or equal to 20mT (threshold). The Hall sensor 31 outputs a high-level signal, and the control component 40 controls the power supply component 50 to supply power to the heating component 20.

[0060] like Figure 4 and Figure 5 As shown, in some embodiments, the Hall sensor 31 is mounted within the second mounting structure 223 described above. The inner diameter of the frame structure of the second mounting structure 223 is adapted to the outer diameter of the Hall sensor 31 so that the Hall sensor 31 is secured within the frame structure of the second mounting structure 223. The Hall sensor 31 is electrically connected to the control component 40 via a wire 311.

[0061] In some embodiments, the magnet 32 ​​is mounted within the mounting hole 22411 of the mounting portion 2241. In other words, the shape and size of the magnet 32 ​​are adapted to the shape and size of the mounting hole 22411, and the magnet 32 ​​is embedded in the mounting hole 22411 of the mounting portion 2241. In some embodiments, the magnet 32 ​​is a permanent magnet; in other embodiments, the magnet 32 ​​may also be an electromagnet, such as a coil, which generates an electromagnetic field when energized.

[0062] The Hall sensor 31 and the magnet 32 ​​described above are located on opposite sides of the receiving space A, so that the Hall sensor 31 can sense the magnetic field signal of the magnet 32. In other embodiments, the Hall sensor 31 may be installed in the first mounting structure 222, and the magnet 32 ​​may be installed in the second mounting structure 223.

[0063] In some embodiments, the magnetic field of the magnet 32 ​​is transmitted to the Hall sensor 31 through the sliding hole 2211 and the transmission hole 2212, thereby making the Hall sensor 31 sense a stronger magnetic field strength of the magnet 32, better signal transmission, and more flexible magnetic field transmission.

[0064] In some embodiments, the shape and size of the magnetic field blocking component 33 are greater than or equal to the shape and size of the magnet 32. In the first position, the magnetic field blocking component 33 can completely block the magnet 32, preventing part of the magnetic field of the magnet 32 ​​from causing the magnetic field strength detected by the Hall sensor 31 to be greater than or equal to the threshold.

[0065] In other embodiments, the magnetic field blocking component 33 can also partially block the magnet 32 ​​by simply reducing the magnetic field of the magnet 32 ​​so that the magnetic field strength detected by the Hall sensor 31 is less than a threshold. In some embodiments, the height of the magnet 32 ​​is less than or equal to half the height of the first mounting plate 2221 and the second mounting plate 2222. After the magnetic field blocking component 33 moves to the second position, the magnet 32 ​​as a whole will not be blocked by the magnetic field blocking component 33.

[0066] like Figure 12 and Figure 13 As shown, the magnetic field blocking component 33 is movably mounted on the first mounting structure 222. The magnetic field blocking component 33 is on the same side as the Hall sensor 31 or the magnet 32. The magnetic field blocking component 33 is located near the receiving space A, and the Hall sensor 31 or the magnet 32 ​​is located away from the receiving space A, so that the magnetic field blocking component 33 can be moved between the Hall sensor 31 and the magnet 32 ​​(first position) and moved out of the Hall sensor 31 and the magnet 32 ​​(second position).

[0067] In some embodiments, the magnetic field blocking assembly 33 may include a first bracket 331 movably disposed between the first mounting plate 2221 and the second mounting plate 2222, with its end extending into the central through hole 2210 through the sliding hole 2211 of the inner cylinder 221, and a magnetic field blocking member 332 mounted on the first bracket 331. When the aerosol generating article 2 is inserted into the central through hole 2210, it presses against the first bracket 331, thereby moving the magnetic field blocking member 332 from the first position to the second position, releasing the magnetic field blocking of the magnet 32 ​​by the magnetic field blocking member 332. The Hall sensor 31 detects a magnetic field strength greater than or equal to a threshold and outputs a high-level signal.

[0068] For reference Figure 11 In some embodiments, the first support 331 may include a main body 3311, a mating part 3312, two guide shafts 3313, and a stop part 3314. The mating part 3312 is installed on the side wall of the main body 3311 near the receiving space A. The two guide shafts 3313 are installed on both sides of the main body 3311 and are slidably installed in two guide grooves 22211. The stop part 3314 is located at the bottom end of the main body 3311. When the magnetic field blocking component 33 is in the first position, the end of the mating part 3312 extends into the central through hole 2210 through the sliding hole 2211 of the inner cylinder 221. When the magnetic field blocking component 33 is in the second position, the end of the mating part 3312 retracts outside the central through hole 2210. When the first support 331 is pressed against the aerosol generating article 2 and moved from the first position to the second position, the first support 331 is located longitudinally parallel to the central axis of the receiving space A and laterally perpendicular to the central axis, so that the mating part 3312 is retracted outside the receiving space A.

[0069] In some embodiments, the length of the mating portion 3312 matches the inclination of the first guide groove 22211. Specifically, when the mating portion 3312 passes through the sliding hole 2211 near the insertion port 120 (the magnetic field blocking component 33 is in the first position), a portion of the mating portion 3312 extends into the receiving space A, which can be pressed against the upper surface of the mating portion 3312 when the aerosol generating article 2 is inserted into the receiving space A. When the mating portion 3312 is located in the sliding hole 2211 away from the insertion port 120, the mating portion 3312 will retract completely into the sliding hole 2211. Understandably, after the aerosol generating article 2 is inserted into the receiving space A, it presses against the mating portion 3312 and moves downward. When the mating portion 3312 moves from the first position to the second position, the mating portion 3312 is housed in the sliding hole 2211, allowing the aerosol generating article 2 to continue to be inserted into the receiving space A. At the same time, the side wall of the mating portion 3312 near the central through hole 2214 will abut against the side of the aerosol generating article 2. After the aerosol generating article 2 is pulled out of the receiving space A, the side wall of the mating part 3312 loses the abutment limit of the aerosol generating article 2, and then the first bracket 331 moves from the second position back to the first position, so that a part of the mating part 3312 extends into the receiving space A again.

[0070] For example, the mechanical connection between the first bracket 331 and the magnetic field blocking component 332 is used to insert the aerosol generating product 2 axially along the central axis of the receiving space A, which is converted into the magnetic field blocking component 33 being located longitudinally parallel to the receiving space A and laterally displaced perpendicular to the central axis, with a displacement of 2-5 mm; the guide groove 221 has an inclination angle of 30°-60°, and its end away from the insertion port 120 is offset outward from the central axis by 1 mm-3 mm.

[0071] In some embodiments, the inclination direction of the first guide groove 22211 allows the first support 331 to move longitudinally by 1 mm along the central axis of the receiving space A when the aerosol generating article 2 is inserted, resulting in a lateral displacement of 0.5 mm perpendicular to the central axis, thereby avoiding the insertion path of the receiving space A. In other embodiments, the distance the first support 331 moves and the inclination angle of the first guide groove 22211 can also be set according to actual needs.

[0072] Comparative experiments show that the volume of the detection component 30 in this scheme is 40% of that in the traditional microswitch scheme, and stable detection can be achieved in a cavity with a diameter of 8mm (or even smaller); the false trigger rate of the traditional capacitive detection scheme is 15%, while the false trigger rate of this scheme is ≤1%.

[0073] In some embodiments, when the mating part 3312 is in the first position, the top end of the mating part 3312 may extend partially from the limiting slot 22422 of the upper stop 2242. The upper stop 2242 may also position the first bracket 331 from the second position to the first position. When the first bracket 331 is in the first position, the top end of the first bracket 331 or the magnetic field blocking member 332 will abut against the upper stop 2242.

[0074] In some embodiments, the main body 3311, the mating part 3312, the guide shaft 3313, and the abutment part 3314 can be spliced, snapped together, or integrally formed. In some embodiments, the guide shaft 3313 can be slidably disposed or rolled within the first guide groove 22211.

[0075] In some embodiments, the magnetic field blocking element 332 is made of permalloy, silicon steel sheet, soft iron, or other materials that can reduce magnetic field penetration. In other embodiments, the magnetic field blocking element 332 and the first support 331 are integrally formed. Alternatively, the first support 331 is the magnetic field blocking element 332, that is, the first support 331 is made of a material that blocks the magnetic field of the magnet 32, and when the first support 331 is in the first position, it can directly block the magnetic field of the magnet 32.

[0076] Refer again Figure 7 In some embodiments, the detection component 30 may further include an elastic element 34, which elastically supports the magnetic field blocking component 33 between the bottom and the upper seat 22. In some embodiments, the elastic element 34 elastically supports the bottom of the abutment portion 3314 of the first bracket 331 and the lower stop portion 2243 of the second bracket 224. The elastic element 34 provides elastic support for the magnetic field blocking component 33, holding the magnetic field blocking component 33 in a first position (e.g., Figure 9 (As shown). Additionally, when the aerosol-generating article 2 is removed from the receiving space A, the magnetic field blocking component 33 moves from the second position to the first position under the elastic force of the elastic member 34. In some embodiments, the elastic member 34 is a columnar spring. In other embodiments, the elastic member 34 may be a coil spring, a constant force spring, etc.

[0077] In some embodiments, the elastic coefficient k of the elastic element 34 needs to satisfy: k = F / Δx, where F is the axial thrust when the aerosol generating article 2 is inserted (typical value 0.5-2N), Δx is the displacement of the magnetic field blocking component 33 (2-5mm), preferably k = 0.1-1N / mm.

[0078] The following section will further explain the aerosol generating device in conjunction with its usage.

[0079] When the aerosol generating device is in use: when the aerosol generating product 2 is inserted, it will press against the mating part 3312 of the first support 331 during the process of inserting the aerosol generating product 2 into the receiving space A, and drive the magnetic field blocking component 33 to move from the first position to the second position. The blocking between the magnet 32 ​​and the Hall sensor 31 is released. The magnetic field strength detected by the Hall sensor 31 is greater than or equal to the threshold. The Hall sensor 31 outputs a high-level signal to the control component 40. The control component 40 controls the power supply component 50 to supply power to the heating component 20. The heating component 20 heats the aerosol generating product 2.

[0080] When the aerosol generating product 2 is pulled out of the receiving space A, the first support 331 loses the contact of the aerosol generating product 2, and the magnetic field blocking component 33 is reset by the elastic force of the elastic element 34, blocking between the Hall sensor 31 and the magnet 32. The magnetic field strength detected by the Hall sensor 31 is less than the threshold, and the Hall sensor 31 outputs a low-level signal to the control component 40. The power supply component 50 interrupts the power supply to the heating component 20, and the heating component 20 stops heating.

[0081] It should be noted that, for those skilled in the art, without departing from the concept of this utility model, the above-mentioned technical features can be freely combined, and several modifications and improvements can be made, all of which fall within the protection scope of this utility model.
