Description

Technical Field

[0001] This application relates to the field of aerosol generation technology, specifically to a delayed-opening heating non-combustible device and its control method. Background Technology

[0002] The heating chamber of the heated non-combustible device contains replaceable heated non-combustible products. The heating element within the chamber heats these products to generate an aerosol that can be inhaled by the user. After a period of use, the heated non-combustible products need to be replaced. Because heated non-combustible devices typically generate temperatures of 200°C to 300°C or even higher to heat the products, both the heated products and the heating chamber will be very hot. If a user comes into contact with the high-temperature heating chamber, they may suffer burns. Summary of the Invention

[0003] This application aims to provide a delayed-opening heated non-combustible device and its control method. Its main purpose is to provide a delayed-opening heated non-combustible device that removes high-temperature heated non-combustible products in an inverted manner to avoid burns.

[0004] According to a first aspect of this application, this application provides a delayed-opening heated non-combustible device, comprising:

[0005] The main body has a heating chamber and a heating assembly. The heating chamber is used to contain a heat-non-combustible product, and the heating assembly is used to heat the heat-non-combustible product in the heating chamber.

[0006] A cover body, which is movably connected to the main body to cover or open the heating cavity; the cover body has an aerosol outflow channel, which communicates with the heating cavity when the cover body covers the heating cavity;

[0007] A locking assembly, movably mounted on the body and reciprocating between a locked position and an unlocked position, is used to lock the cover in the locked position to limit the cover to a covered state, and to release the cover in the unlocked position to limit the cover to an open state.

[0008] A delayed-opening component is disposed on the main body. The delayed-opening component is used to cooperate with the locking component to restrict the movement of the locking component when the temperature of the heating chamber reaches a preset temperature, and to release the locking component when the temperature of the heating chamber is lower than the preset temperature, so that the locking component is in an movable state.

[0009] In some embodiments, the delayed-opening component includes a temperature detection unit and a limiting unit, both of which are disposed on the main body. The temperature detection unit is thermally connected to the heating cavity and is used to sense the temperature of the heating cavity. The limiting unit is used to restrict the movement of the locking component when the temperature detection unit detects that the temperature of the heating cavity has reached a preset temperature, and to release the locking component when the temperature detection unit detects that the temperature of the heating cavity is lower than the preset temperature, so that the locking component can move to the unlocked position.

[0010] In some embodiments, the limiting unit includes a driving unit and a sliding blocking member. The main body is provided with a sliding guide portion, and the sliding blocking member is slidably disposed on the sliding guide portion and can reciprocate between a limiting position and a release position under the drive of the driving unit. In the limiting position, the sliding blocking member restricts the movement of the locking assembly, and in the release position, the sliding blocking member releases the locking assembly. The temperature detection unit is used to output a release signal when it detects that the temperature of the heating cavity is lower than a preset temperature, and the driving unit can drive the sliding blocking member to move from the limiting position to the release position according to the release signal.

[0011] In some embodiments, the driving unit includes an electromagnetic attraction unit and a magnetic drive unit. The magnetic drive unit includes a magnetic swing member and a first elastic reset member. The magnetic swing member has a magnetic attraction portion, a pivot portion, and a connecting portion. The pivot portion is located between the magnetic attraction portion and the connecting portion. The magnetic swing member is rotatably connected to the main body through the pivot portion. The connecting portion is rotatably connected to the sliding stop member. The first elastic reset member acts between the main body and the magnetic swing member to provide an elastic force to the magnetic swing member that causes the magnetic attraction portion to move away from the electromagnetic attraction unit. The electromagnetic attraction unit is energized to generate an electromagnetic attraction force to attract the magnetic attraction portion.

[0012] When the electromagnetic attraction unit is de-energized, the first elastic reset member causes the connecting part to drive the sliding blocking member to remain in the limit position; when the electromagnetic attraction unit is energized, the magnetic attraction part is attracted by the electromagnetic attraction unit and overcomes the elastic force of the first elastic reset member, and the connecting part drives the sliding blocking member to move from the limit position to the release position.

[0013] In some embodiments, the locking assembly includes a locking member, an unlocking member, and a second elastic reset member. The main body is provided with a first through hole. The unlocking member is movably installed in the first through hole and can be reciprocally slidably disposed in the first through hole between the locking position and the unlocking position. The locking member is connected to the unlocking member, and the cover is provided with a locking groove.

[0014] The unlocking member can lock the locking member into the locking groove when it is in the locked position to limit the cover to a covered state, or it can disengage the locking member from the locking groove when it is in the unlocked position to allow the cover to be opened to an open state.

[0015] The main body is provided with a limiting part, and the second elastic reset member is disposed between the limiting part and the unlocking member; the second elastic reset member is used to apply an elastic force away from the limiting part to the unlocking member so as to keep the locking member locked in the lock groove when the locking member is in the locked position.

[0016] When the unlocking member is in the locked position, the sliding blocking member is placed between the unlocking member and the limiting part, and restricts the second elastic reset member from being elastically compressed.

[0017] In some embodiments, the delayed-opening component includes a thermo-deformable element that is in thermal contact with the heating component to sense the temperature inside the heating cavity through heat transfer. The thermo-deformable element has thermal deformation characteristics. When the temperature of the heating cavity reaches a preset temperature, the thermo-deformable element takes on a first shape, and when the temperature is below the preset temperature, it takes on a second shape. In the first shape, the portion of the thermo-deformable element facing away from the heating component abuts against the locking component to restrict the movement of the locking component. In the second shape, the locking component can move relative to the main body to release the locking component, so that the locking component is in a movable state.

[0018] In some embodiments, the heated non-combustible device further includes a connected sensor unit and a heating controller. The sensor unit is located on the side of the main body or the cover facing each other to detect whether the cover is in a covered state or an open state. The heating controller is configured to activate the heating component when the cover is in a covered state and to control the heating component to stop working when the cover is in an open state.

[0019] In some embodiments, the locking assembly includes a lock body, a bolt, and a third resilient reset member; one end of the lock body is movably disposed within the main body, a second through hole is formed in the side wall of the main body, and the other end of the lock body passes through the second through hole and is disposed outside the main body;

[0020] The latch is connected to the lock body in a driving manner. The latch is used to lock with the cover under the action of the lock body to restrict the cover from being in a covered state, or to unlock the cover so that the cover can be opened to an open state.

[0021] The thermo-deformable element restricts the movement of the locking element in a first shape, and the thermo-deformable element releases the restriction on the locking element in a second shape.

[0022] The third elastic reset member is used to apply an elastic force to the lock body to drive the bolt toward the cover body, so as to maintain the bolt and the cover body locked after the temperature-induced deformation member releases the restriction on the lock body.

[0023] In some embodiments, a flip-connecting assembly is further included, wherein the cover and the body are flip-connected via the flip-connecting assembly, and the cover can be in a covered state and an open state via the flip-connecting assembly. The flip-connecting assembly is used to provide power for the cover to be in the open state; in the covered state, the cover covers the heating cavity, and in the open state, the cover opens the heating cavity.

[0024] In some embodiments, a rotary connection assembly is further included, wherein the cover and the body are rotatably connected via the rotary connection assembly, the heating cavity is located on one side of the body, and the cover can be rotated relative to the body in a plane parallel to one side of the body to a covered state or an open state via the rotary connection assembly; in the covered state, the cover covers the heating cavity, and in the open state, the cover opens the heating cavity.

[0025] According to a second aspect of this application, this application provides a control method for the aforementioned delayed-opening heating non-combustible device, comprising the following steps:

[0026] When the temperature of the heating chamber reaches a preset temperature, the delayed opening component restricts the movement of the locking component, and the movement of the locking component is restricted.

[0027] When the temperature of the heating chamber is lower than the preset temperature, the delayed opening component releases the locking component, and the locking component can be operated to release the cover.

[0028] In some embodiments, the delayed-opening component includes a temperature detection unit, and the step of releasing the locking component further includes:

[0029] The temperature detection unit senses the temperature of the heating chamber and provides the sensing result to the delay-on component;

[0030] or,

[0031] The delayed-on component includes a thermo-deformable element, which is in thermally conductive contact with the heating component and has thermal deformation characteristics; the control method includes:

[0032] When the temperature of the heating chamber is lower than the preset temperature, the temperature-induced deformation element deforms into a second shape without interfering with the locking assembly;

[0033] When the temperature of the heating chamber reaches a preset temperature, the temperature-induced deformation element takes on a first shape and interferes with the locking assembly, thus restricting the movement of the locking assembly.

[0034] When the temperature of the heating chamber is lower than a preset temperature, the limiting unit releases the locking assembly.

[0035] In some embodiments, the control method further includes:

[0036] When the cover is in the covered state, the heating component is activated;

[0037] When the cover is in the open state, the heating component is controlled to stop working.

[0038] According to the delayed-opening heated non-combustible device and its control method in the above embodiments, when the heating chamber is at a preset temperature, the delayed-opening component restricts the locking component to lock the cover. When the heating chamber is below the preset temperature, the locking component releases the cover, and the cover can be opened. Afterward, the heated non-combustible product can be dropped naturally in an inverted manner, which greatly reduces the risk of burns to the user caused by the dropped heated non-combustible product and improves the safety of using this heated non-combustible device.

[0063] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0064] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0065] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0066] The heated non-combustible device heats a heated non-combustible product placed in a heating chamber using a heating component, causing the product to generate an edible aerosol. The heated non-combustible product of this application may consist only of a matrix, which can be formed by die-casting a mixture of tobacco powder or other plant powders with a certain proportion of polyols, flavorings, and binders. The heated non-combustible product typically has a porous structure. Upon heating, the tobacco powder or plant powders, polyols, and flavorings volatilize, generating aerosols that cause the heated non-combustible product to collapse, resulting in a reduction in its overall volume. After the heated non-combustible product is heated and replaced with a new one, the user can manually open the lid and pour out the product by inverting it. During this process, the user keeps the lid open by hand. Because the heated non-combustible product is heated at a high temperature and its volume shrinks after heating, there is a high risk of burns to the user's hands during the fall.

[0067] To address the aforementioned issues, this application provides a delayed-opening heating non-combustible device and its control method, which enables the delayed opening of the lid, effectively solving the problem of burns when opening the lid directly and improving safety during use.

[0068] See Figure 1 As shown, the delayed-opening heating non-combustible device provided in this embodiment includes a main body 10, a cover 20, a locking assembly 30, and a delayed-opening assembly 40.

[0069] The main body 10 has a heating chamber 510 and a heating assembly 50. The heating chamber 510 is used to contain the heat-non-combustible product, and the heating assembly 50 is used to heat the heat-non-combustible product within the heating chamber 510. The heating assembly 50 can be a heating needle or heating plate extending into the heating chamber 510 to heat the heat-non-combustible product from the center. Alternatively, the heating assembly 50 can be a heating tube or a radiant heater surrounding the heating chamber 510 to circumferentially heat the heat-non-combustible product. Or, the heating assembly 50 can be a heating structure where hot air enters from the bottom for heating with or without oxygen.

[0070] This embodiment uses a heating structure in which the heating component 50 enters the hot airflow from the bottom for aerobic or anaerobic heating as an example. The heating component 50 is similar to a cup shape, and the heating cavity 510 is formed in the inner cavity of the cup shape. Please refer to the following embodiments for details.

[0071] The cover 20 is movably connected to the main body 10 to cover or open the heating chamber 510. The cover 20 has an aerosol outflow channel 610, which is in communication with the heating chamber 510 when the cover 20 covers the heating chamber 510.

[0072] In this embodiment, the heating component 50 is disposed inside the main body 10, and the heating component 50 should also have an opening 5101 (e.g., Figure 9 As shown, the opening 5101 is in communication with the heating chamber 510 so that a heat-resistant non-combustible product can be placed into or removed from the heating chamber 510 through the opening 5101. Of course, the opening 5101 should also be exposed on one side of the main body 10.

[0073] The cover 20 can cover or open the heating cavity 510 by flipping, rotating, sliding, etc., as can be seen in the following embodiments.

[0074] The locking assembly 30 is movably mounted on the main body 10 and can be switched back and forth between a locked position and an unlocked position. The locking assembly 30 is used to lock the cover 20 in the locked position to limit the cover 20 to a covered state covering the heating cavity 510. The locking assembly 30 is also used to release the cover 20 in the unlocked position to limit the cover 20 to a movably open state opening the heating cavity 510.

[0075] The delayed opening component 40 is disposed on the main body 10. The delayed opening component 40 is used to cooperate with the locking component 30 to restrict the movement of the locking component 30 when the temperature of the heating chamber 510 reaches the preset temperature. The delayed opening component 40 is also used to release the locking component 30 when the temperature of the heating chamber 510 is lower than the preset temperature, so that the locking component 30 is in an unlocked position, so as to release the cover 20 and make the cover 20 movably open in the open state of the open heating chamber 510.

[0076] It should be noted that the preset temperature is the temperature within the heating chamber 510 that can heat the heat-not-burning product and generate an aerosol. This temperature can be in the range of 60℃-300℃. Within this temperature range, the delayed opening component 40 restricts the locking component 30 from releasing the cover 20. If the heat-not-burning product is removed within this temperature range, there is a risk of burns. However, the temperature range below the preset temperature can be less than 60℃. Within this temperature range, the delayed opening component 40 releases the locking component 30, which in turn releases the cover 20, allowing it to be opened. The heat-not-burning product can then be inverted to fall naturally, greatly reducing the risk of burns from the falling product and improving the safety of this heat-not-burning device.

[0077] The process of the heating chamber 510's temperature decreasing from a preset temperature to a temperature lower than the preset temperature is achieved by the heating chamber 510 cooling naturally, which achieves the function of delayed opening of the lid.

[0078] See Figure 2As shown, the delayed opening component 40 includes a temperature detection unit 41 and a limiting unit 42. Both the temperature detection unit 41 and the limiting unit 42 are disposed on the main body 10. The temperature detection unit 41 is thermally connected to the heating cavity 510 and is used to sense the temperature of the heating cavity 510. The limiting unit 42 is used to restrict the movement of the locking component 30 when the temperature detection unit 41 detects that the temperature of the heating cavity 510 has reached a preset temperature, so as to restrict the cover 20 to be in a covered state by the locking component 30. The limiting unit 42 is also used to release the locking component 30 when the temperature detection unit 41 detects that the temperature of the heating cavity 510 is lower than the preset temperature, so that the locking component 30 can move to the unlocked position to release the cover 20, and the cover 20 can be opened to the open state.

[0079] See Figure 5 , Figure 12 as well as Figure 17 As shown, the limiting unit 42 includes a driving unit 42' and a sliding blocking member 423. The main body 10 is provided with a sliding guide part 11. The sliding blocking member 423 can reciprocate between the limiting position and the release position under the drive of the driving unit 42'. In the limiting position, the sliding blocking member 423 restricts the movement of the locking assembly 30 to limit the cover 20 to a covered state. In the release position, the sliding blocking member 423 releases the locking assembly 30, and the locking assembly 30 is in a movable state. By operating the locking assembly 30, the cover 20 can be released, and the cover 20 can be opened to an open state. The temperature detection unit 41 is used to output a release signal when the temperature of the heating chamber 510 is detected to be lower than a preset temperature. The electromagnetic attraction unit 421 generates an electromagnetic attraction force according to the release signal to attract the magnetic attraction transmission unit 422. The driving unit 42' can drive the sliding blocking member 423 from the limiting position to the release position according to the release signal, thereby releasing the locking assembly 30.

[0080] See Figure 17As shown, the drive unit 42' includes an electromagnetic attraction unit 421 and a magnetic attraction transmission unit 422. The magnetic attraction transmission unit 422 includes a magnetic attraction swing member 4221 and a first elastic reset member 4223. The magnetic attraction swing member 4221 has a magnetic attraction part 4224, a pivot part 4225, and a connecting part 4226. The pivot part 4225 is located between the magnetic attraction part 4224 and the connecting part 4226. The magnetic attraction swing member 4221 is rotatably connected to the main body 10 through the pivot part 4225, and the connecting part 4226 is rotatably connected to the sliding resistor. The stop 423 and the first elastic reset member 4223 act between the main body 19 and the magnetic swing member 422. The first elastic reset member 4223 provides an elastic force to the magnetic swing member 4221, causing the magnetic part 4224 to move away from the electromagnetic engagement unit 421. This allows the magnetic swing member 4221 to swing around the pivot 4225 in the first swing direction, and through the connecting part 4226, it drives the sliding stop 423 to remain in the limited position, thereby restricting the movement of the locking assembly 30 and thus limiting the cover 30 to the covered state. The electromagnetic engagement unit 421 is energized to generate electromagnetic attraction to engage the magnetic part 4224. Specifically, when the temperature of the heating chamber 510 detected by the temperature detection unit 41 is lower than the preset temperature, a release signal is issued. The electromagnetic attraction unit 421 generates an electromagnetic attraction force to attract the magnetic attraction part 4224. The magnetic attraction swinging member 4221 swings around the pivot part 4225 in the second swinging direction, and drives the sliding blocking member 423 from the limiting position to the release position through the connecting part 4226, so that the locking assembly 30 is in an active state. In this state, operating the locking assembly 30 can release the cover 20. The first swinging direction and the second swinging direction are the directions in which the magnetic attraction swinging member 4221 swings around the pivot part 4225, which can be clockwise and counterclockwise, respectively.

[0081] When the electromagnetic attraction unit 421 is de-energized, the first elastic reset member 4223 causes the connecting part 4226 to drive the sliding blocking member 423 to remain in the limit position. When the electromagnetic attraction unit 421 is energized, the magnetic attraction part 4224 is attracted by the electromagnetic attraction unit 421 and overcomes the elastic force of the first elastic reset member 4223. The connecting part 4226 drives the sliding blocking member to move from the limit position to the release position.

[0082] In this embodiment, the main body 10 is provided with a first limiting member 4222, and the magnetic swing member 4224 also has a top abutment 4227 located between the pivot part 4225 and the magnetic part 4224. The first elastic reset member 4223 is disposed between the first limiting member 4222 and the top abutment 4227. The first elastic reset member 4223 is a compression spring disposed between the first limiting member 4222 and the top abutment 4227.

[0083] In some embodiments, the first elastic reset member 4223 may also be a tension spring disposed on the side of the magnetic swing member 4224 facing away from the electromagnetic attraction unit 421. Of course, the first elastic reset member 4223 may also be disposed above the pivot portion 4225 of the magnetic swing member 4224, and a compression spring or a tension spring may also be disposed thereon. The specific configuration can be determined according to actual needs and is not limited here.

[0084] In this embodiment, as Figure 17 As shown, the electromagnetic attraction unit 421 includes an iron core 4211, a coil 4212, and a DC power supply module 4213. The iron core 4211 passes through the coil 4212. The DC power supply module 4213 is electrically connected to the coil 4212. The temperature detection unit 41 is electrically connected to the DC power supply module 4213. In the initial state, the DC power supply module 4213 is disconnected from the coil 4212. When the temperature detection unit 41 detects that the temperature of the heating chamber 510 is lower than the preset temperature and outputs a release signal, the DC power supply module 4213 is connected to the coil 4212. Under the action of electromagnetic induction, the iron core 4211 generates a magnetic field to attract the magnetic attraction part 4224.

[0085] In one embodiment of this application, see Figure 5 , Figure 8 , Figure 15 and Figure 17 As shown, the locking assembly 30 includes a locking member 31, an unlocking member 32, and a second elastic reset member 33. The main body 10 can be an integral block-shaped cuboid structure or a hollow structure. In the figure, it is drawn as a shell to facilitate the illustration of the internal structure of the main body 10. This application does not limit the specific structural form of the main body 10. In this embodiment, the main body 10 is a closed hollow cuboid structure. The main body 10 is provided with a first through hole 12. The unlocking member 32 is movably installed in the first through hole 12 and can be slidably disposed in the first through hole 12 between the corresponding positions of the locking position and the unlocking position. The locking member 31 is connected to the unlocking member 32, and the cover 20 is provided with a locking groove 211.

[0086] like Figure 8 and Figure 15 As shown, the unlocking member 32 also has a stop portion 321 protruding from it. The stop portion 321 is located in the part of the unlocking member 32 placed inside the main body 10. The stop portion 321 cooperates with the inner wall of the main body 10 to restrict the unlocking member 32 from disengaging from the first through hole 12.

[0087] The unlocking member 32 can lock the locking member 3 into the locking groove 211 when it is in the locked position, so as to limit the cover 20 to the covered state, or the unlocking member 32 can disengage the locking member 31 from the locking groove 211 when it is in the unlocked position, so that the cover 20 can be opened and is in the open state.

[0088] The main body 10 is provided with a limiting part 13, and a second elastic reset member 33 is disposed between the limiting part 13 and the unlocking member 32. The second elastic reset member 33 is used to apply an elastic force away from the limiting part 13 to the unlocking member 32 so that when the locking member 31 is in the locked position, the locking member 31 is locked in the locking groove 211.

[0089] In a specific embodiment, the unlocking member 32 is inserted into the first through hole 12 in a reciprocating sliding manner. It can be in a locked position or an unlocked position relative to the first through hole 12. During its sliding process, it can drive the locking member 31 to lock into the slot 211 or disengage from the slot 211.

[0090] In this embodiment, the locking member 31 is provided with a locking hook 311. In the locked position, the locking hook 311 is locked into the locking groove 211, and in the unlocked position, the locking hook 311 is disengaged from the locking groove 211.

[0091] To facilitate operation of the unlocking member 32, the part of the unlocking member 32 located outside the main body 10 is also provided with a pressing part 322. The pressing part 322 can be pressed, and under the action of the pressing force, the unlocking member 32 can drive the locking member 31 to slide from the position corresponding to the locking position to the position corresponding to the unlocking position. The locking hook 311 of the locking member 31 can then disengage from the locking groove 211, and the cover 20 is unrestricted and can be flipped relative to the main body 10 to the flipped position.

[0092] When the locking member 31 is switched from the unlocked position to the locked position under the action of the unlocking member 32, the second elastic reset member 33 is elastically compressed and stores elastic potential energy. After the force applied to the pressing part 322 is eliminated, the second elastic reset member 33 releases the elastic potential energy and drives the locking member 31 to switch from the locked position to the unlocked position through the unlocking member 32.

[0093] In this embodiment, when the unlocking member 32 is in the locked position, the sliding blocking member 423 is placed between the unlocking member 32 and the limiting part 13 to restrict the second elastic reset member 33 from being elastically compressed, so as to keep the locking hook 311 of the locking member 31 locked in the locking groove 211.

[0094] like Figure 17 As shown, the limiting part 13 is a cover structure. The limiting part 13 is also provided with a clearance hole 131 to avoid the sliding blocking member 423, so that the sliding blocking member 423 can be placed between the unlocking member 32 and the limiting part 13 to limit the unlocking member 32.

[0095] See Figure 16 As shown, another structural form of the locking member 31 is illustrated. This locking member 31 includes a blocking portion 312, a first connecting portion 313, and a second connecting portion 314. The first connecting portion 313 is disposed between the blocking portion 312 and the second connecting portion 314, and the second connecting portion 314 abuts against the unlocking member 32. Figure 15 As shown, the host 10 is also provided with a third rotating shaft 17 inside. The third rotating shaft 17 is rotatably connected to the connection between the first connecting part 313 and the blocking part 312. In some embodiments, a second shaft hole 315 is also provided at the connection between the first connecting part 313 and the blocking part 312. The third rotating shaft 17 is rotatably inserted into the second shaft hole 315, so that the locking member 31 is rotatably connected to the inside of the host 10.

[0096] like Figure 16 As shown, there is a first included angle between the blocking part 312 and the first connecting part 313, and a second included angle between the first connecting part 313 and the second connecting part 314. Specifically, the second connecting part 314 is arranged vertically, and the first connecting part 313 is inclined to connect to the second connecting part 314 in a direction away from the second limiting member 16. The blocking part 312 is inclined to connect to the first connecting part 313 in a direction closer to the second limiting member 16. The first connecting part 313 and the blocking part 312 form an approximately V-shaped structure. When the locking member 31 rotates around the third pivot 17 in a first rotation direction or a second rotation direction, the blocking part 312 is engaged with or disengaged from the slot 211. It can be understood that the first connecting part 313 and the second connecting part 314 can also be without an included angle, and the blocking part 312 can be inclined relative to the first connecting part 313 in a direction away from the second limiting member 16.

[0097] In a specific embodiment, with Figure 15 Taking the orientation shown as an example, when the blocking part 312 engages with the slot 211, a pressing force is applied to the pressing part 422. The unlocking part 32 moves to the right, causing the locking part 31 to rotate around the third pivot 17 in the second rotation direction (counterclockwise), so that the blocking part 312 disengages from the slot 211. During this process, the second elastic reset part 33 stores elastic potential energy. When the force applied to the pressing part 422 is removed, the second elastic reset part 33 releases the elastic potential energy, and the locking part 31 can rotate around the third pivot 17 in the first rotation direction (clockwise), so that the blocking part 312 is exposed at the upper end of the main unit 10. When the cover 20 is pressed down, the blocking part 312 can enter the cover 20 and engage with the slot 211.

[0098] See Figures 18-22 As shown, another structural form of the delayed-opening component 40 is illustrated. This delayed-opening component 40 includes a thermo-deformable element 43, which is in thermal contact with the heating component 50. The thermo-deformable element 43 can sense the temperature inside the heating cavity 510 through heat transfer. The thermo-deformable element 43 has thermal deformation characteristics. The thermo-deformable element 43 can take on a first shape when the temperature of the heating cavity 510 reaches a preset temperature, and take on a second shape when the temperature of the heating cavity 510 is lower than the preset temperature.

[0099] The preset temperature is the temperature inside the heating cavity 510 sensed by the thermo-deformable element 43 through heat transfer. The preset temperature at which the thermo-deformable element 43 can change into the first shape can be considered high temperature, for example, 60℃-300℃. The temperature below the preset temperature is the temperature inside the heating cavity 510 after it has naturally cooled down after the cover 20 needs to be opened and the heating component 50 stops working. For example, the temperature below the preset temperature can be below 60℃. The thermo-deformable element 43 can be a memory metal with a two-way memory effect, such as a nickel-titanium alloy. When the temperature is low and close to room temperature, it has a flat or basically flat shape, and when the temperature is high, the curvature increases and the bending amplitude increases.

[0100] like Figures 4-15 As shown, the heating cavity 510 is disposed on one side of the main body 10. The locking assembly 30 can lock the connection between the cover 20 and the main body 10 when the cover 20 covers the heating cavity 510 on one side of the main body 10. The thermo-deformable element 43 that undergoes the first deformation can limit the locking assembly 30 to prevent the locking assembly 30 from releasing the lock between the cover 20 and the main body 10, so that the cover 20 is restricted from opening and is in a closed state by the locking assembly 30. Alternatively, the thermo-deformable element 43 that undergoes the second deformation can release the restriction on the locking assembly 30, so that the cover 20 can move relative to the main body 10. At this time, the cover 20 can be opened and is in an open state without being restricted by the locking assembly 30.

[0101] In this embodiment, as Figure 18 When the thermo-deformable component 43 deforms into a first shape at a preset temperature, the portion of the thermo-deformable component 43 facing away from the heating assembly 50 abuts against the locking assembly 30. The thermo-deformable component 43, having undergone the first shape change, can limit the locking assembly 30, thereby restricting the movement of the cover 20 relative to the main body 10 through the locking assembly 30 and keeping the cover 20 in a closed state, thus covering the heating cavity 510. Figure 19 When the thermo-deformable component 43 deforms into a second shape at a temperature lower than the preset temperature, the thermo-deformable component 43 that has undergone the second shape change releases the restriction on the locking component 30, specifically by disengaging from the locking component 30. Then the locking component 30 can move relative to the main body 10, thereby releasing the restriction on the cover 20, and allowing the cover 20 to be opened to the open state.

[0102] In the above embodiments, the temperature-induced deformation element 43 switches from a preset temperature to a temperature lower than the preset temperature under the natural cooling of the heating chamber 510. This process delays the opening of the cover 20, so that the temperature of the heated non-combustible product drops to a temperature that avoids scalding the user.

[0103] See Figure 18 and Figure 19As shown, another structural form of the locking assembly 30 is presented. The locking assembly 30 includes a lock body 34, a latch 35, and a third elastic reset member 36. One end of the lock body 34 is movably placed inside the main body 10. A mounting hole 111 is provided on the side wall of the main body 10, and the other end of the lock body 34 passes through the mounting hole 111 and is placed outside the main body 10. The latch 35 is drivenly connected to the lock body 34. The latch 35 is used to lock with the cover 20 under the action of the lock body 34 to restrict the cover 20 to be closed in the closed state, or the latch 35 is used to unlock with the cover 20 under the action of the lock body 34 to open the cover 20 to the open state.

[0104] The latch 35 keeps the cover 20 in a closed state by locking it with the cover 20. When the latch 35 is unlocked from the cover 20, the cover 20 can be opened to the open state. In the first shape, the thermostatically deformable element 43 abuts against the lock body 34 to restrict its movement and keep the latch 35 locked to the cover 20. In the second shape, the thermostatically deformable element 43 can release the restriction on the lock body 34, allowing the lock body 34 to move the latch 35 and release the lock from the cover 20.

[0105] In a specific embodiment, the lock body 34 is movably installed in the mounting hole 111 and can slide back and forth along the axis of the mounting hole 111 relative to the mounting hole 111. The thermo-deformable element 43 restricts the movement of the lock body 34 in the first shape and releases the restriction on the lock body 34 in the second shape, allowing the lock body 34 to move. The moving lock body 34 drives the bolt 35 to lock or unlock with the cover 20, thus restricting the cover 20 to be closed in the closed state, or allowing the cover 20 to be opened to the open state.

[0106] When the lock body 34 is restricted from moving by the thermo-deformable element 43, the latch 35 remains locked to the cover 20, thus restricting the cover 20 from closing to the closed state of covering the heating cavity 510. When the lock body 34 is released from the thermo-deformable element 43, the movement of the lock body 34 causes the latch 35 to release from the locked state with the cover 20, allowing the cover 20 to open to the open state and exposing the heating cavity 510.

[0107] The third elastic reset member 36 is used to apply an elastic force to the lock body 34 to drive the lock tongue toward the cover body 20, so as to maintain the lock tongue 35 locked to the cover body 20 after the temperature-induced deformation member 43 releases the restriction on the lock body.

[0108] See Figure 21 and Figure 22 As shown, the cover 20 can be slidably connected to the main body 10, wherein the sliding direction is a plane parallel to one side of the main body 10, and one side of the main body 10 is the side where the heating cavity 510 is provided. The locking tongue 35 can lock with the cover 20 after the cover 20 covers the heating cavity 510, preventing the relative sliding of the cover 20 and the main body 10.

[0109] In this embodiment, preventing the cover 20 from sliding relative to the body 10 is limited by the thermo-deformable element 43 in a first shape, such as... Figure 21 and Figure 22 As shown, a first limiting part 212 is provided on the cover 20. When the cover 20 covers the heating cavity 510 and the thermotropic deformation member 43 changes into a first shape upon sensing that the temperature of the heating cavity 510 is at a preset temperature, the thermotropic deformation member 43 in the first shape abuts against the first limiting part 212, preventing the cover 20 from sliding relative to the main body 10, thus locking the latch 35 with the cover 20. When the thermotropic deformation member 43 senses that the temperature of the heating cavity 510 is lower than the preset temperature, a second shape occurs. The thermotropic deformation member 43 in the second shape disengages from the first limiting part 212, thus unlocking the latch 35 from the cover 20. At this time, the cover 20 can slide relative to the main body 10 to be in an open state.

[0110] It should be noted that a driving structure can also be provided for the sliding of the cover 20 relative to the main body 10. For example, a spring can be provided, and the elastic potential energy stored after the spring is compressed can drive the cover 20 to slide relative to the main body 10.

[0111] See Figure 20 As shown, in some embodiments, the latch 35 is fixedly connected to the cover 20, and a hook 351 is provided on the latch 35. The lock body 34 placed inside the main body 10 is provided with a locking hole 3411 and a second limiting part 3412. The locking hole 3411 is located on the part of the lock body 34 placed inside the main body 10. The hook 351 cooperates with the locking hole 3411 to lock the lock body 34 and the latch 35. The second limiting part 3412 is used to limit the lock body 34 from disengaging from the mounting hole 111 and plays a role in preventing the lock body 34 from disengaging.

[0112] Specifically, the lock body 34 can move within the mounting hole 111 to be in either a first or second position. In the first position, the cover 20 is in a covered state, concealing the heating chamber 510. The latch 351 of the bolt 35 can be locked into the locking hole 3411 of the lock body 34. The first position of the lock body 34 is limited by the thermo-deformable element 43, which undergoes a first shape change, to keep the cover 20 in a covered state. When it is necessary to open the cover 20, the lock body 34 is moved to the second position, and the latch 351 of the bolt 35 can disengage from the locking hole 3411 of the lock body 34. Furthermore, the thermo-deformable element 43, which undergoes a second shape change, releases the restriction on the lock body 34, allowing the cover 20 to be opened.

[0113] See Figure 18 and Figure 19As shown, the main body 10 is provided with a mounting part 113, and the lock body 34 is sleeved with the mounting part 113. The lock body 34 is provided with a first stop part 3413, and a third elastic reset member 36 is elastically compressed between the mounting part 113 and the first stop part 3413. After the lock body 34 changes position relative to the main body 10, the lock body 34 can be restored to its initial position by the compressed third elastic reset member 36.

[0114] In this embodiment, the lock body 34 has a head end 34a and a tail end 34b. The head end 34a is placed outside the main body 10 for pressing operation. The tail end 34b passes through the mounting part 113 and is provided with a second stop part 3414. The third elastic reset member 36 is located between the mounting part 113 on the side away from the second stop part 3414 and the first stop part 3413.

[0115] See Figure 18 and Figure 20 As shown, the first shape of the thermo-deformable element 43 is curved, wherein the end of the thermo-deformable element 43 with the first shape is curved can abut against the locking assembly 30, and the curvature of the second shape of the thermo-deformable element 43 is less than the curvature of the first shape.

[0116] In some embodiments, the second shape of the temperature-induced deformation element 43 can be considered to be curved, while the first shape is straight.

[0117] See also Figure 18 , Figure 19 , Figure 21 and Figure 22 As shown, the thermo-deformable component 43 is provided with a support member 431. The thermo-deformable component 43 is strip-shaped, column-shaped, or rod-shaped. The thermo-deformable component 43 is divided into a first segment 4301 and a second segment 4302. The first segment 4301 is located between the heating component 50 and the support member 431, and the second segment 4302 is located between the support member 431 and the side wall of the main body 10. The first segment 4301 is used to transfer the heat from the heating component 50 to the second segment 4302. The second segment 4302 is used to cooperate with the locking component 30 to present a first shape or a second shape at a first deformation temperature or a second deformation temperature, respectively, thereby restricting the opening and closing state of the cover 20.

[0118] In this application, to achieve automatic opening of the cover 20, such as Figure 1 As shown, this application also provides an automatic opening mechanism 70 between the cover 20 and the main body 10. The automatic opening mechanism 70 is used to automatically drive the cover 20 to open relative to the main body 10 when the locking component 30 releases the cover 20. The opening method can be flipping, rotating or sliding. Please refer to the following embodiments for details.

[0119] See Figures 3-10As shown, the automatic opening mechanism 70 includes a flip connection assembly 71, which includes a first rotating shaft 711 and a flip drive 712. The cover 20 is flipped and connected to the main body 10 via the first rotating shaft 711. The flip drive 712 is installed between the cover 20 and the main body 10. When the locking assembly 30 is in the unlocked state, the flip drive 712 drives the cover 20 to flip relative to the main body 10 around the axis of the first rotating shaft 711 to the flipped position. The driving of the flip drive 712 enables the cover 20 to automatically flip relative to the main body 10 around the axis of the first rotating shaft 711, thereby realizing the automatic opening of the cover 20.

[0120] The flipping drive component 712 can be either an electric drive structure or a mechanical drive structure, depending on the actual needs.

[0121] In this application, to reduce costs, the flipping drive component 712 includes a first torsion spring 7121, which is sleeved on the first rotating shaft 711. The first free end 71211 of the first torsion spring 7121 is connected to the cover 20, and the second free end 71212 of the first torsion spring 7121 is connected to the main body 10. When the cover 20 rotates relative to the main body 10 around the axis of the first rotating shaft 711 to the covering position covering the heating cavity 510, the first torsion spring 7121 stores elastic potential energy. When the locking assembly 30 is in the unlocked state, the first torsion spring 7121 releases its elastic potential energy, causing the cover 20 to rotate relative to the main body 10 around the axis of the first rotating shaft 711 to the flipped position, thus enabling the cover 20 to achieve an automatic flipping function.

[0122] When the locking assembly 30 is in the unlocked state, the first torsion spring 7121 instantaneously releases its elastic potential energy, causing the cover 20 to flip rapidly. See [link to relevant documentation] for details. Figure 6 and Figure 7 As shown, the flip-connecting assembly 71 provided in this embodiment also includes a first damping buffer 713. One end of the first damping buffer 713 is connected to the main body 10, and the other end faces the cover 20. The first damping buffer 713 is used to abut against the cover 20 and generate compression deformation during the flip-to-flip position, so as to apply an elastic force to the cover 20 to slow down the flip-to-flip speed of the cover 20 relative to the main body 10. The first damping buffer 713 can ensure that the cover 20 flips slowly relative to the main body 10 through the generated elastic force. The first damping buffer 713 can be, for example, a gas strut, with its two ends connected to the main body 10 and the cover 20 respectively.

[0123] See Figures 11-15As shown, the automatic opening mechanism 70 includes a rotary connection assembly 72, which includes a second rotating shaft 721 and a rotary drive 722. The second rotating shaft 721 is disposed on the main body 10 in a direction parallel to the axis of the heating chamber 510. Specifically, a portion of the shaft of the second rotating shaft 721 is fixed to the main body 10. The cover 20 is rotatably connected to the main body 10 via the second rotating shaft 721, and the cover 20 can rotate relative to the main body 10 around the axis of the second rotating shaft 721. The rotary drive 722 is installed between the cover 20 and the main body 10, and is used to drive the cover 20 to rotate relative to the main body 10 to an open state after the locking assembly 30 releases the cover 20. Preferably, the axis of the heating chamber 510 is coaxial with the axis of the main body 10, so that when the cover 20 rotates relative to the main body 10, the cover 20 can rotate in a plane parallel to one side of the main body 10.

[0124] The rotary drive 722 can be electrically driven, which can automatically rotate the cover 20 relative to the main unit to the open or closed position. Of course, the rotary drive 722 can also be mechanical, which can automate the rotation to the open position, while the rotation from the open position to the closed position can be achieved by manual pushing.

[0125] In this application, to reduce costs, the rotary drive component 722 includes a second torsion spring 7221, which is sleeved on the second rotating shaft 721, such as... Figure 14 As shown, the cover 20 has a first slot 23, and the main body 10 has a second slot 11. The first free end 72211 of the second torsion spring 7221 engages with the first slot 23 of the cover 20, and the second free end 72212 of the second torsion spring 7221 engages with the second slot 11 of the main body 10. During the process of the cover 20 rotating from an open state to a covered state relative to the main body 10 in a plane parallel to one side of the main body 10 around the axis of the second rotating shaft 721, the second torsion spring 7221 is elastically compressed and stores elastic potential energy. When the locking assembly 30 releases the cover 20, the second torsion spring 7221 releases its elastic potential energy, forcing the cover 20 to rotate from a covered state to an open state relative to the main body 10 in a plane parallel to one side of the main body 10 around the axis of the second rotating shaft 721, thus providing power for the rotation of the cover 20.

[0126] During the process of the cover 20 rotating from the covered position to the open position relative to the main body 10 in a plane parallel to the side of the main body 10 about the axis of the second rotation axis 721, in order to keep it in the open position, see Figure 14As shown, a limiting member 24 is provided on the side of the cover 20 facing the main body 10, and a limiting fitting part 14 is also provided on the side of the main body 10. The limiting member 24 and the limiting fitting part 14 cooperate with each other to limit the angle of rotation of the cover 20 relative to the main body 10 when the cover 20 rotates relative to the main body 10 in a plane parallel to the side of the main body 10, thereby limiting the opening angle of the second torsion spring 7221, protecting the second torsion spring 7221, and restricting the cover 20 to maintain an open state that can expose the heating chamber 510.

[0127] It should be noted that the limiting fitting part 14 is the side wall of the internal cavity of the main body 10. Of course, in some embodiments, since the limiting member 24 protrudes from the cover 20, the main body 10 can adopt a hollow structure with an opening.

[0128] In one embodiment of this application, the cover 20 rotates rapidly due to the instantaneous release of elastic potential energy by the second torsion spring 7221. To address this, the rotary connection assembly 72 provided in this application also includes a damping element, see [link to relevant documentation]. Figure 14 As shown, the cover 20 has a first shaft hole 25. Part of the second rotating shaft 721 is fixedly connected to one side of the main body 10, and the remaining part of the second rotating shaft 721 passes through the first shaft hole 25. In a specific embodiment, the main body 10 has a screw hole 15. The part of the second rotating shaft 721 fixed to the main body 10 has external threads and is fixedly connected to the main body 10 by screwing with the screw hole 15. A damping element is disposed between the second rotating shaft 721 and the first shaft hole 25 to reduce the rotation speed of the cover 20 relative to the main body 10.

[0129] In this application, a protrusion 723 is also provided in the radial direction of the second rotating shaft 721. The protrusion 723 is located on the part of the second rotating shaft 721 that is placed outside the cover 20, which can prevent the cover 20 from detaching from the second rotating shaft 721.

[0130] The cover 20 is also provided with a suction nozzle 60, such as Figures 3-6 As shown, an outer cover 22 can also be provided on the cover body 20. The outer cover 22 is fastened to the cover body 20 to protect the nozzle component 60. The nozzle component 60 is provided with a nozzle channel 610, which is connected to the aerosol outflow channel 610. Figure 23As shown, the side wall of the suction nozzle 60 has an air inlet 611 that communicates with the suction nozzle channel 601, and the inner wall of the side wall of the suction nozzle 60 has a first air inlet channel 612. The heating assembly 50 includes a heating cup 51, and the side wall of the heating cup 51 has a second air inlet channel 511. The inner cavity of the heating cup 51 is formed as a heating chamber 510. When the cover 20 covers the heating chamber 510, the first air inlet channel 512 communicates with the second air inlet channel 511. The end of the second air inlet channel 511 away from the first air inlet channel 512 has an air delivery hole 512 located on the inner wall of the heating cup 51. The air inlet 611, the first air inlet channel 512, the second air inlet channel 511, the air delivery hole 512, and the heating chamber 510 are interconnected. In actual use, the user draws air through the nozzle 60, while external air enters the heating chamber 510 through the air inlet 611, the first air inlet channel 512, the second air inlet channel 511, and the air delivery hole 512.

[0131] See Figure 23 As shown, the heating assembly 50 also includes a heat exchange core 52, a heating chamber 53, and a gas collecting plate 54. The heat exchange core 52, the gas collecting plate 54, and the heating chamber 53 are sequentially fixed inside the heating cup 51 along the height direction of the heating cup 51. The heat exchange core 52 is located between the heating chamber 53 and the bottom of the heating cup 51. The heat exchange core 52 is used to heat the gas flowing into the heating cup 51 from the gas inlet 512. The heating chamber 53 defines a heating cavity 510.

[0132] Specifically, the heat exchange core 52 is provided with multiple heat exchange holes 521 through it, and the air collecting plate 54 is provided with multiple air collecting holes 541 through it. External air enters into each heat exchange hole 521 of the heat exchange core 52 through the air supply hole 512. The heat exchange core 52 can generate heat to heat the air flowing through the heat exchange holes 521. The heated airflow is then transported to the heating chamber 510 defined by the heating chamber 53 through the air collecting holes 541.

[0133] In some embodiments, an air-gathering block 513 is also provided at the air inlet 512, which can increase the flow rate of external air entering through the air inlet 512.

[0134] See also Figure 23As shown, a reducing pipe 62 is also provided in the inner cavity of the suction nozzle 60, and an extension 63 is defined at the top end of the suction nozzle 60. The reducing pipe 62 sequentially forms a first mixing chamber 621, an acceleration chamber 622, and a second mixing chamber 623 along the axial direction of the suction nozzle 60. The first mixing chamber 621, the acceleration chamber 622, and the second mixing chamber 623 are sequentially arranged along the airflow outlet direction and are interconnected, so the aerosol is output sequentially through the first mixing chamber 621, the acceleration chamber 622, and the second mixing chamber 623. In this embodiment, a first one-way valve 55 is also provided on the cover 20, and a second one-way valve 56 is also provided between the air outlet 512 and the second air inlet channel 511. The first one-way valve 55 is located on the channel wall of the second air inlet channel 511 and communicates with the first mixing chamber 621, allowing a small portion of the air entering through the second air inlet channel 511 to enter the first mixing chamber 621 to cool the aerosol. The second one-way valve 56 allows air entering through the second air intake channel 511 to flow unidirectionally through the air supply port 512 and supply it to the heat exchange port 521, preventing aerosol leakage. The acceleration chamber 622 is preferably a pipe with a radial dimension at least smaller than that of the first mixing chamber 621, which can accelerate the output flow rate of the aerosol and reduce suction resistance. The second mixing chamber 623 can buffer the aerosol accelerated by the acceleration chamber 622, enabling it to achieve further cooling.

[0135] In this embodiment, when the cover 20 is opened, the heating component 50 can stop working; when the cover 20 is closed, the heating component 50 starts. For automatic control of the opening and closing of the heating component 50, see [link to relevant documentation]. Figure 1 As shown, the delayed-opening, heat-not-burning device provided in this embodiment also includes a connected sensor unit 80 and a heating controller 90. The sensor unit 80 is disposed on the side of the main body 10 or the cover 20 facing each other. The sensor unit 80 can be one of a pressure sensor, a photoelectric sensor, or a Hall sensor. In this embodiment, the sensor unit 80 is disposed on the side of the cover 20 facing the main body 10 to detect whether the cover 20 is in a covered or open state. For example, the change in the distance between the main body 10 and the cover 20 can be detected. When the distance between the two is 0, it can be determined that the cover 20 is in a covered state. The heating controller 90 is electrically connected to the heating component 50 and the sensor unit 80. The heating controller 90 is configured to start the heating component 50 when the cover 20 is in a covered state, and to stop the heating component 50 when the cover 20 is in an open state. Of course, the heating controller 90 determines whether the cover 20 is covered or open through the sensor unit 80. In other words, when the sensor unit 80 detects that the cover 20 is covered, the heating controller 90 starts the heating component 50, and when the sensor unit 80 detects that the cover 20 is open, the heating component 50 stops working.

[0136] In some embodiments, the sensor unit 80 can be disposed on the locking assembly 30. When the locking assembly 30 releases the cover 20, it can be determined that the cover 20 is in an open state. At this time, the heating controller 90 can control the heating assembly 50 to stop working. Conversely, when the locking assembly 30 locks the cover 20, it can be determined that the cover 20 is in a covered state. At this time, the heating controller 90 controls the heating assembly 50 to start. For example, the sensor unit 80 is a pressure sensor. The sensor unit 80 can be disposed on the locking member 31. For example, the sensor unit 80 is disposed on the side of the blocking part 312 facing the cover 20 to detect the contact state between the blocking part 312 and the cover 20, or the sensor unit 80 is disposed between the unlocking member 32 and the locking member 31 to detect the pressing force of the locking member 31.

[0137] See Figure 24 As shown, this embodiment provides a control method for a heating non-combustible device based on delayed lid opening, including the following steps:

[0138] In step S100, the temperature of the heating chamber 510 is detected, which can serve as the basis for whether the delayed opening component 40 releases the locking component 30, so that the cover 20 can be released when the temperature of the heating chamber 510 is lower than the preset temperature, so that the cover 20 can be opened.

[0139] In some embodiments, the delayed opening component 40 includes a temperature detection unit 41, which may be, for example, a temperature sensor, capable of sensing the temperature of the heating cavity 510 and providing the sensing result to the delayed opening component 40. When the temperature detection unit 41 detects that the temperature of the heating cavity 510 is a preset temperature, the delayed opening component 40 restricts the activity of the locking component 30. When the temperature detection unit 41 detects that the temperature of the heating cavity 510 is lower than the preset temperature, the delayed opening component 40 releases the locking component 30, and the locking component 30 can be in an active state.

[0140] In some embodiments, the delayed-opening component 40 includes a thermo-deformable element 43, which is in thermal contact with the heating component 50, for example, directly connected to the heating component 50. The thermo-deformable element 43 has thermal deformation characteristics. When the temperature of the heating cavity 510 is lower than a preset temperature, the thermo-deformable element 43 deforms into a second shape without interfering with the locking component 30, allowing the locking component 30 to be in an active state. However, when the temperature of the heating cavity 510 reaches the preset temperature, the thermo-deformable element 43 takes on a first shape and interferes with the locking component 30, thereby restricting the movement of the locking component 30.

[0141] When the thermo-deformable element 43 is used, the temperature detection unit 41 can be omitted, and there is no need for signal transmission. The activity state of the locking assembly 30 can be automatically controlled simply by utilizing the thermo-deformable characteristics of the thermo-deformable element 43 itself. Specifically, in the step S200 of releasing the locking assembly, when the temperature of the heating chamber 510 reaches the preset temperature, the delayed opening component 40 restricts the activity of the locking assembly 30. With the activity of the locking assembly 30 restricted, the cover 20 can be locked by the locking assembly 30 to restrict the cover 20, thus restricting the cover 20 to a state of covering the heating chamber 510.

[0142] When the temperature of the heating chamber 510 is lower than the preset temperature, the delayed opening component 40 releases the locking component 30, the locking component 30 removes the restriction on the cover 20, the locking component 30 can be operated to release the cover 20, and the cover 20 can be in the open state.

[0143] The cover 20 is opened relative to the main body 10 and is in an open state. Specifically, the cover 20 can be automatically opened by the automatic opening mechanism 70. For details on the structure and features of the automatic opening mechanism 70, please refer to the above embodiment.

[0144] In step S300 of opening and closing the heating component, when the sensor unit 80 detects that the cover 20 is in a covered state, the heating controller 90 controls the heating component 50 to start. When the sensor unit 80 detects that the cover 20 is in an open state, the heating controller 90 controls the heating component 50 to stop working.

[0145] In summary, the delayed-opening heated non-combustible device and its control method provided in this application have the following features: when the heating chamber is at a preset temperature, the delayed-opening component restricts the locking component to lock the cover; when the heating chamber is below the preset temperature, the locking component releases the cover, and the cover can be opened. The heated non-combustible product can then be removed by inverting it or by using a tool, which greatly reduces the risk of burns to users from falling heated non-combustible products and improves the safety of using this heated non-combustible device.

[0146] The above examples illustrate this application only to aid understanding and are not intended to limit its scope. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the ideas presented.
