Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1 and fig. 2, fig. 1 is a schematic diagram of a functional module of a heating element according to an embodiment of the present disclosure, and fig. 2 is a schematic diagram of a circuit of the heating element according to an embodiment of the present disclosure. Specifically, the heating assembly 10 includes a heating element 11 and a control unit 12, and the control unit 12 controls the heating element 11 to work to atomize the substrate to be atomized.
Specifically, the control unit 12 controls conduction between the battery assembly 20 connected to the heating assembly 10 and the heating element 11. When heating is needed, the control unit 12 controls the electrical connection between the battery assembly 20 and the heating element 11, and the battery assembly 20 supplies power to the heating element 11, so that the heating element 11 generates heat. When heating is stopped, the control unit 12 controls the battery assembly 20 to be electrically disconnected from the heating element 11, at which time the battery assembly 20 stops supplying power to the heating element 11.
As can be understood, the control unit 12 controls the on/off between the battery assembly 20 and the heating element 11 by using the PWM signal, specifically, the battery assembly 20 supplies power to the heating element 11 when the PWM signal is at a high level, so that the heating element 11 is heated, and stops supplying power to the heating element 11 when the PWM signal is at a low level, so that the heating element 11 is cooled. Specifically, in order to avoid the situation that the heating element 11 is continuously heated to burn the heating element 11 or cause scorched smell, the heating is stopped after the heating element 11 is heated for a period of time, and then the heating element 11 is continuously heated after the heating is stopped for a period of time.
It will be appreciated that the longer the heating time, i.e. the higher the temperature of the heating element 11, there will generally be a safe time when the heating time does not exceed the safe time, the temperature of the heating element 11 is within the safe temperature, and when the heating time exceeds the safe time, the temperature of the heating element 11 is too high, and there is a risk of overheating. Therefore, in the present application, the control unit 12 determines whether there is an overheating risk in the heating element 11 based on the heating time, and when there is an overheating risk in the heating element 11, the electrical connection between the battery assembly 20 and the heating element 11 is disconnected, and heating is stopped.
Specifically, to prevent the heating element 11 from being heated for too long, which may result in too high temperature of the heating element 11, and thus affect the atomization effect and may cause unsafe risks, the control unit 12 determines whether the heating element 11 is at an overheating risk based on the heating time, and disconnects the electrical connection between the battery assembly 20 and the heating element 11 in response to the overheating risk of the heating element 11. In one embodiment, the control unit 12 counts the heating time of the heating element 11 within a certain period of time, if the heating time of the heating element 11 is greater than the preset heating time, it is determined that the heating element 11 is at an overheating risk, the control unit 12 controls the battery assembly 20 to be electrically disconnected from the heating element 11, the heating element 11 is stopped from heating, and the temperature gradually decreases to the target temperature.
In one embodiment, the control unit 12 turns on or off the electrical connection between the battery assembly 20 and the heating element 11 through the PWM signal, for example, when the control unit 12 detects that the heating time of the heating element 11 is greater than the preset heating time, the control unit 12 turns off the electrical connection between the battery assembly 20 and the heating element 11 through the PWM signal; when the control unit 12 detects that the heating time of the heating element 11 is less than the preset heating time, the control unit 12 turns on the electrical connection between the battery assembly 20 and the heating element 11 through the PWM signal.
Through the method, the heating time of the heating element 11 can be effectively controlled, the temperature of the heating element 11 is guaranteed to be at a safe temperature, other components in the heating assembly 10 are prevented from being damaged due to overheating of the heating element 11, the safety stability of the heating assembly 10 is improved, and the atomization effect is guaranteed. In one embodiment, as shown in fig. 2, the heating assembly 10 further includes a switch unit 121, the switch unit 121 being disposed between the heating element 11 and the battery assembly 20; the control unit 12 is connected with the switch unit 121 and controls the switch unit 121 to be conducted so as to heat the heating element 11; the control unit 12 further detects the on time of the switching unit 121, determines whether there is an overheating risk of the heating element 11 based on the on time, and in response to the overheating risk of the heating element 11, the control unit 12 controls the switching unit 121 to turn off. It is understood that the on time of the switching unit 121 is a heating time of the heating element 11. In one embodiment, the switching unit 121 is a MOS transistor. Specifically, the switch unit 121 may be a PMOS transistor or an NMOS transistor. In another embodiment, the switch unit 121 may also be a transistor, such as a P-type transistor or an N-type transistor, which is not limited in this embodiment.
In one embodiment, the control unit 12 determines the heating time of the heating element 11 by detecting the on-time of the switch unit 121, and when the heating time of the heating element 11 is detected to be greater than the preset heating time, the control unit 12 outputs the PWM signal to control the switch unit 121 to turn off.
In another embodiment, the control unit 12 detects the accumulated on-time of the switch unit 121 within the preset time period Δ T, and determines whether there is an overheating risk in the heating element 11 based on the accumulated on-time. Specifically, when the control unit 12 controls the electrical connection between the battery assembly 20 and the heating element 11 by using the PWM signal, there are a plurality of high and low level periods in the Δ T period, the control unit 12 counts the accumulated time of the high level in the Δ T, and determines whether the heating element 11 has an overheating risk based on the accumulated time of the high level. It will be appreciated that at high levels, the battery assembly 20 heats the heating element 11. Specifically, as shown in fig. 3, during the preset time period Δ T, the switching unit 121 has a plurality of on-times T1, T2, T3 and a plurality of off-times T1 ', T2', T3 ', that is, at T1, T2, T3, the heating element 11 is heated, and at T1', T2 ', T3', the heating element 11 is not heated. The control unit 12 integrates a plurality of on-times of the switch unit 121 within the preset time period Δ T, that is, the control unit 12 calculates a sum of the on-times within Δ T, where T is T1+ T2+ T3, compares the sum T of the on-times with the preset on-time within the preset time period Δ T, and if the control unit 12 detects that the integrated on-time T of the switch unit 121 within the preset time period Δ T is greater than the preset on-time, it indicates that the actual heating time of the heating element 11 is greater than the preset heating time, and the heating element 11 has an overheating risk, and the control unit 12 controls the switch unit 121 to turn off.
In an embodiment, the control unit 12 detects the accumulated on-time T in real time during the heating process, for example, during the heating process at time T1, the control unit 12 determines whether T1 is within Δ T, if yes, further determines whether T1 is greater than the preset on-time, if no, there is no overheating risk, and if yes, there is an overheating risk. Further, in the process of heating at time T2, the control unit 12 determines whether T1+ T2 is within Δ T, if yes, further determines whether T1+ T2 is greater than a preset on-time, if not, there is no overheating risk, and if yes, there is an overheating risk. Until the accumulated on-time is determined to be greater than the preset on-time, it is determined that there is an overheating risk, at which point heating of the heating element 11 is stopped.
Referring to fig. 4, in an embodiment, the control unit 12 detects a first on time of the switching unit 121; in response to the first on-time not being greater than the preset time period Δ T and in response to the first on-time not being greater than the time threshold, there is no risk of overheating of the heating element 11. That is, in the preset time period Δ T, if the first on time of the switch unit 121 is not greater than the preset on time threshold, it indicates that the actual heating time of the heating element 11 is less than the preset heating time, and the heating element 11 does not have an overheating risk. In this embodiment, the first on-time may be one-time switch on-time, and the first on-time may also include multiple times of switch on-time as long as the first on-time is not greater than the preset time period Δ T.
In one embodiment, the control unit 12 detects the second on time of the switching unit 121; in response to the sum of the second conduction time and the first conduction time not being greater than the preset time period Δ T and in response to the sum of the second conduction time and the first conduction time not being greater than the time threshold, then there is no risk of overheating of the heating element 11. That is, if the sum of the first on time and the second on time of the switch unit 121 is not greater than the preset time period Δ T, and the sum of the first on time and the second on time is not greater than the preset on time threshold, it indicates that the actual heating time of the heating element 11 is less than the preset heating time, and the heating element 11 does not have an overheating risk. In the present embodiment, the first on-time and the second on-time may be respectively one or more times as long as the sum of the times is not greater than the preset time period Δ T.
In one embodiment, in response to the sum of the second on time and the first on time being no greater than the preset time period Δ T and in response to the sum of the second on time and the first on time being greater than a time threshold, the heating element 11 is at risk of overheating. It can be understood that if the sum of the first on time and the second on time of the switching unit 121 is not greater than the preset time period Δ T, and the sum of the first on time and the second on time is greater than the preset on time threshold, it indicates that the actual heating time of the heating element 11 is greater than the preset heating time, the heating element 11 has an overheating risk, and the control unit 12 controls the switching unit 121 to turn off.
In one embodiment, the heating element 11 provided by the present application includes a heating unit R1 and a temperature measuring unit R2, wherein the heating unit R1 is connected to the battery pack 20 through the switch unit 121, the temperature measuring unit R2 is parallel to the heating unit R1 and is connected to the control unit 12, the heating assembly 10 further includes a sampling unit R3, and the sampling unit R3 is connected in series with the temperature measuring unit R2 and is connected to the control unit 12.
Specifically, the output end of the battery pack 20 is connected to the first end of the switch unit 121, the second end of the switch unit 121 is connected to the first end of the heat generating unit R1, and the control unit 12 controls the on/off of the switch unit 121 through the PWM signal, so as to control the electrical connection between the battery pack 20 and the heat generating unit R1. The temperature measuring unit R2 is arranged in parallel with the heating unit R1, and the temperature measuring unit R2 is connected with the sampling unit R3 in series and is connected with the control unit 12. The control unit 12 can detect the voltage V1 of the sampling unit R3, and the resistance of the sampling unit R3 Is known, so as to calculate the current Is of the sampling unit R3. According to the same principle of the current of the series circuit, the resistance value of the temperature measuring unit R2 at the current moment is as follows:
and the resistance value of the temperature measuring unit R2 represents the current resistance value of the heating unit R1, so that the current resistance value of the heating unit R1 at the current moment is obtained.
In the heating assembly provided by the present application, the control unit 12 detects the actual on-time of the switch unit 121 within the preset time period Δ T, and compares the actual on-time with the preset on-time threshold of the switch unit 121 within the preset time period Δ T, to determine whether the heating element 11 has an overheating risk, and in response to the overheating risk of the heating element 11, the control unit 12 controls the switch unit 121 to be turned on and off, so as to ensure the heating effect of the heating element 11 and prevent the heating element 11 from overheating and damaging the heating element 11 and other components.
Referring to fig. 5, a schematic flow chart of a first embodiment of a control method of a heating assembly of the present application specifically includes:
step S11: detecting the heating time of a heating element of the heating assembly, and judging whether the heating element has overheating risks or not based on the heating time.
Specifically, the control unit controls conduction between a battery assembly connected with the heating assembly and the heating element so as to enable the heating element to perform heating operation, and detects the heating time of the heating element, wherein the control unit judges whether the heating element has overheating risk or not based on the heating time. It is understood that the control unit counts the heating time of the heating element within a certain period of time, and determines that the heating element is at risk of overheating if the heating time of the heating element is greater than a preset heating time.
Step S12: in response to the heating element being at risk of overheating, stopping heating the heating element.
Specifically, if the heating element is judged to have the overheating risk, the control unit controls the battery assembly to be electrically disconnected with the heating element, and the heating element is stopped from heating.

That is, in a preset time period, the switch unit has a plurality of on-times and off-times, the control unit accumulates the plurality of on-times of the switch unit in the preset time period, and compares the accumulated on-times with the preset on-times in the preset time period, and if the control unit detects that the accumulated on-times of the switch unit in the preset time period is greater than the preset on-times, it indicates that the actual heating time of the heating element is greater than the preset heating time, and the heating element has an overheating risk.
