[0026] To facilitate the understanding of the present application, the present application will be described more comprehensively below with reference to the relevant drawings.

At the same time, the term "and / or" used in this specification includes any and all combinations of the related listed items.

[0032] As described in the background art, in the related art, for the reset technology of the heat-not-burn device, an independent reset button needs to be set up on the circuit, so a reset operation hole needs to be reserved in the structure of the heat-not-burn device, and the reset button is arranged in the reset operation hole. However, the design of the operation hole destroys the structural integrity of the heat-not-burn device, affecting the waterproof performance and appearance. Also, a special tool is required to trigger the reset button during reset, making the reset operation difficult.

[0033] Based on the above technical problems, the inventors have developed the technical solution of the embodiments of the present application. Specifically, the embodiments of the present application provide a heat-not-burn device, including a switch module, a delay conversion module, a reset module, a controller, and a load. The delay conversion module is respectively connected to the switch module and the reset module, and the controller is respectively connected to the reset module, the switch module, and the load. The delay conversion module is configured to output a target level after the switch module is triggered and closed for a preset duration; the reset module is configured to output a reset signal after receiving the target level; the controller is configured to perform a reset after receiving the reset signal; and control the load to operate when the reset signal is not received and it is detected that the switch module is triggered and closed.

[0034] By adopting the above technical solution, it is possible to reuse the switch module originally used to control the load to implement the reset function, so that the heat-not-burn device does not need to be provided with an independent reset button, thereby avoiding the problems of affecting the structural integrity and difficult operation due to the need to set an operation hole for the independent reset button, and further making the structure of the heat-not-burn device more complete and facilitating the user to perform the reset operation.

[0035] The above is the core idea of this application. Next, the technical solutions in the embodiments of this application will be clearly and completely described with reference to the accompanying drawings in the embodiments of this application.

[0036] Figure 1 The following is a schematic structural diagram of a heat-not-burn device provided by an embodiment of this application. As Figure 1 shown, the heat-not-burn device includes a switch module 100, a delay conversion module 200, a reset module 300, a controller 400, and a load. The delay conversion module 200 is respectively connected to the switch module 100 and the reset module 300, and the controller 400 is respectively connected to the reset module 300, the switch module 100, and the load.

[0037] The delay conversion module 200 is configured to output a target level after the switch module 100 is triggered to close for a preset duration. The reset module 300 is configured to output a reset signal after receiving the target level. The controller 400 is configured to perform a reset after receiving the reset signal; and control the load to operate when the reset signal is not received and it is detected that the switch module 100 is triggered to close.

[0038] In actual implementation, a control program is stored in the controller 400. When the controller 400 is in a normal working state, the controller 400 controls the load to work according to the stored control program. Exemplarily, the controller 400 can control the load to heat at a preset heating power to enable the heat-not-burn device to work properly. When the controller 400 crashes due to software design defects or external ESD events, etc., it cannot continue to control the load according to the control program, making the heat-not-burn device unable to work properly.

[0039] In this embodiment, when the controller 400 is in a normal working state, and it detects that the switch module 100 is triggered to close and the reset signal is not received, it determines that the received is a control signal to turn on the load, and thus controls the load to operate according to the stored control program.

[0040] When the controller 400 is in an abnormal state such as crashing, the user can trigger the switch module 100 to close for a preset duration to enable the delay conversion module 200 to output a target level, and the target level can be set according to specific circumstances. Exemplarily, the target level is a low level.

[0041] After the reset module 300 receives the low level output by the delay conversion module 200, it outputs a reset signal to enable the controller 400 to perform a reset according to the reset signal.

[0042] Among them, the type and structure of the controller 400 can be set according to the actual situation. Exemplarily, the controller 400 can include an MCU (Microcontroller Unit, micro control unit) or other microprocessing units. The type and structure of the load can also be set in combination with the actual situation. In one embodiment, the load includes a heating element, such as a heating body, and the heating body is connected to the controller 400. The controller 400 is reset after receiving a reset signal; when the reset signal is not received and it is detected that the switch module 100 is triggered to close, the heating body is controlled to work, so that the heat-not-burn device works properly. In actual implementation, the number and connection relationship of the heating bodies can be set according to specific situations, and this embodiment does not limit this.

[0043] In the above heat-not-burn device, when implementing the reset function, the switch module 100 originally used to control the load is reused. Thus, there is no need to set an independent reset button, avoiding the problems of affecting the structural integrity and difficult operation caused by setting an independent reset button, and further making the structure of the heat-not-burn device more complete. Moreover, compared with the related art in which users usually need to use tools to trigger the reset button in the operation hole, the operation convenience of users is greatly improved.

[0044] In one embodiment, as Figure 2 shown, the switch module 100 includes a resistor R1 and a switch S1. The first end of the switch S1 is connected to the power supply VCC through the resistor R1, the second end of the switch S1 is grounded, and the first end of the switch S1 is also connected to the controller 400.

[0045] Among them, the size of the resistor R1 needs to be set according to the actual circuit. The resistor R1 can be an independent resistor or an equivalent circuit composed of multiple resistors.

[0046] The type of the switch S1 does not need to be limited. Exemplarily, the switch S1 is a button, and when the button is pressed, the switch S1 closes. In actual implementation, after the switch S1 is triggered to close, the level at the first end of the switch S1 is pulled low, and the controller 400 detects this level change and determines that the switch S1 is triggered.

[0047] In one embodiment, the delay conversion module 200 includes an energy storage unit 210, a charging unit 220, and a delay discharge unit 230. The first end of the energy storage unit 210 is respectively connected to the first end of the charging unit 220, the first end of the delay discharge unit 230, and the reset module 300, and the second end of the energy storage unit 210 is grounded; the second ends of the charging unit 220 and the delay discharge unit 230 are both connected to the first end of the switch S1.

[0048] The charging unit 220 is used to charge the energy storage unit 210 so that the first end of the energy storage unit 210 is in the initial level state. The delay discharge unit 220 discharges the energy storage unit 210 when the switch S1 is triggered to close. After the switch S1 is triggered for a preset duration, the first end of the energy storage unit 210 is in the target level state.

[0049] It can be understood that the energy storage unit 210 includes components capable of storing and releasing electrical energy. In one embodiment, the energy storage unit 210 includes a capacitor C1. The first end of the capacitor C1 is respectively connected to the first end of the charging unit 220, the first end of the delay discharge unit 230, and the reset module 300, and the second end of the capacitor C1 is grounded.

[0050] Among them, the initial level and the target level are different. In actual implementation, the initial level can be a high level and the target level is a low level. Further, when the reset module 300 receives a low level, that is, the target level, it outputs a reset signal to the controller 400. The reset signal can be a logic low level signal; when the reset module 300 receives a high level, it outputs a logic high level signal to the controller 400.

[0051] It can be understood that the preset duration can be specifically set according to the structure and parameters of the delay discharge unit 230, for example, it is 5 seconds.

[0052] Specifically, when the heat-not-burn device is powered on, the power supply VCC charges the capacitor C1 through the resistor R1 and the charging unit 220, and the first end of the capacitor C1 reaches a high level. At this time, the reset module 300 receives a level signal from low to high, and then outputs a reset logic level from low to high to reset the controller 400 normally.

[0053] When the switch S1 is normally triggered (the trigger duration is usually less than 3 seconds), the voltage across the capacitor C1 remains at a high level, the reset module 300 outputs a high level signal, and the controller 400 maintains a normal working state. For example, after the switch S1 is pressed, the controller 400 controls the heating element to heat.

[0054] When the switch S1 is triggered for a long time, after the capacitor C1 discharges through the delay discharge unit 230 and the switch S1 for a preset duration, the voltage across the capacitor C1 drops to a low level. At this time, the reset module 300 receives a level signal from high to low and outputs a low level signal (i.e., the reset signal) to reset the controller 400.

[0055] After stopping triggering the switch S1, the power supply VCC charges the capacitor C1 through the resistor R1 and the charging unit 220, the first end of the capacitor C1 reaches a high level, and the reset module 300 outputs a reset logic level from low to high, so that the controller 400 completes the reset.

[0056] In this embodiment, when the switch S1 is normally triggered, the controller 400 maintains a normal working state, so that the heat-not-burn device is in a normal working state; when the switch S1 is triggered for a long time, the capacitor C1 is discharged through the delay discharge unit 230 and the switch S1, so that the first end of the capacitor C1 has a falling level, and then the reset module 300 outputs a reset signal, thereby triggering the reset of the controller 400. Thus, on the basis of not affecting the normal function of the switch S1, the hardware reset function of the controller 400 is realized by long-pressing the switch S1.

[0057] In actual implementation, the structures of the charging unit 220 and the delay discharge unit 230 can be set according to actual situations. In one embodiment, as Figure 3 shown, the charging unit 220 includes a diode D1. The cathode of the diode D1 is connected to the first end of the energy storage unit 210, and the anode of the diode D1 is connected to the first end of the switch S1. Thus, by setting the diode D1, rapid charging of the capacitor C1 can be achieved.

[0058] In one embodiment, the delay discharge unit 230 includes a discharge resistor R2. The first end of the discharge resistor R2 is connected to the first end of the energy storage unit 210, and the second end of the discharge resistor R2 is connected to the first end of the switch S1. It can be understood that the above preset duration is related to the resistance value of the discharge resistor R2 and the capacitance value of the capacitor C1. In actual implementation, the preset duration needs to be determined in combination with the resistance value of the discharge resistor R2 and the capacitance value of the capacitor C1.

[0059] In one embodiment, please continue to refer to Figure 2 , the reset module 300 includes a logic level conversion unit 310 and a reset unit 320. The input end of the logic level conversion unit 310 is connected to the delay conversion module 200, and the output end of the logic level conversion unit 310 is connected to the reset unit 320.

[0060] The logic level conversion unit 310 controls the reset unit 320 to output a reset signal after receiving the target level output by the delay conversion module.

[0061] Specifically, the logic level conversion unit 310 can perform logic level conversion. When the first end of the capacitor C1 is at a high level, it outputs a logic high level signal; when the first end of the capacitor C1 is at a low level, it outputs a logic low level signal, thereby further controlling the reset unit 320 to output a corresponding signal.

[0062] The specific circuit structures of the logic level conversion unit 310 and the reset unit 320 can be set according to actual needs. In one embodiment, as Figure 3As shown, the reset unit 320 includes a reset resistor R3 and a reset capacitor C2. The first end of the reset capacitor C2 is connected to the power supply VCC through the reset resistor R3, the second end of the reset capacitor C2 is grounded, and the first end of the reset resistor R3 is also connected to the controller 400 and the output end of the logic level conversion unit 310 respectively.

[0063] After the switch S1 is triggered and closed for a preset duration, the logic level conversion unit 310 outputs a low-level signal, and the reset capacitor C2 discharges through the internal circuit of the logic level conversion unit 310 to form a reset low level. After the switch S1 is disconnected, the logic level conversion unit 310 outputs a high-level signal, and the logic level conversion unit 310 and the reset resistor R3 charge the reset capacitor C2 together to form a reset logic level that rises from low to high, completing the normal reset of the controller 400.

[0064] In one embodiment, the logic level conversion unit 310 includes a comparison circuit. The input end of the comparison circuit serves as the input end of the logic level conversion unit 310, and the output end of the comparison circuit serves as the output end of the logic level conversion unit 310.

[0065] The type of the comparison circuit does not need to be limited. In one embodiment, the comparison circuit can be a logic gate circuit U1, and the logic gate circuit U1 can be an OR gate or an AND gate. As Figure 3 shown in the embodiment, the comparison circuit is an OR gate U1, and its two input ends are both connected to the first end of the capacitor C1, and the output end is connected to the first end of the reset capacitor C2. In another embodiment, the comparison circuit can also be a comparator or a switching transistor, etc.

[0066] For a better understanding of the above embodiments, the following will be combined with Figure 3 embodiments are described in detail. Specifically, the load in the heat-not-burn device is a heating element H1, and the switch S1 is a button. The logic level conversion unit 310 includes an OR gate U1. The input terminal A and the input terminal B of the OR gate U1 are connected. When the input is at a low level, the OR gate U1 outputs a logic low level, and when the input is at a high level, the OR gate U1 outputs a logic high level. The time constant of the delay discharge unit 230 is relatively large, and the preset duration is 5 seconds.

[0067] When the heat-not-burn device is powered on, the power supply VCC quickly charges the capacitor C1 through the resistor R1 and the diode D1. The voltage of the capacitor C1 reaches the input high level of the OR gate U1, and the OR gate U1 outputs a high level, and together with the reset resistor R3, charges the reset capacitor C2 to form a reset logic level that rises from low to high, so that the controller 400 is normally reset.

[0068] When the button S1 is normally pressed, the voltage across the capacitor C1 is maintained at a high level, causing the OR gate U1 to always output a high level. At this time, the heat-not-burn device remains in a normal operating state. For example, after the button S1 is pressed, the controller 400 activates the heating element H1 to heat, so that the function of the button S1 remains normal without generating a reset signal.

[0069] When the button S1 is pressed for a long time, the capacitor C1 discharges through the discharge resistor R2 and the button S1, and the voltage across the capacitor C1 drops to a low level. The OR gate U1 outputs a low level, and the reset capacitor C2 discharges through the internal circuit of the OR gate U1 to form a reset low level. After the button S1 is released, the power supply VCC quickly charges the capacitor C1 through the resistor R1 and the diode D1. When the voltage of the capacitor C1 reaches the input high level of the OR gate U1, the OR gate U1 outputs a high level, and together with the reset resistor R3, charges the reset capacitor C2 to form a reset logic level that rises from low to high to complete the normal reset of the controller 400.

[0070] In the above heat-not-burn device, when implementing the reset function, the hardware reset of the controller 400 is achieved by long-pressing the button S1, and it does not affect the normal function of the button S1 as a function button. Thus, there is no need to set up an independent reset button, avoiding the problems of affecting the structural integrity and difficult operation caused by setting up an independent reset button. Furthermore, the structure of the heat-not-burn device becomes more complete, and the operation convenience for users can be improved.

[0071] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as falling within the scope described in this specification.

[0072] The above-described embodiments merely represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
