Fig. 1 shows a schematic circuit diagram of an atomizer device. As shown in fig. 1, the atomization device mainly includes a control assembly 11 and an atomization assembly 12, the control assembly 11 includes a battery Bat and a control unit U, the atomization assembly 12 includes a heating resistor R, and a substance to be atomized (not shown in fig. 1) in a liquid storage chamber, and the heating resistor R is immersed in the substance to be atomized. One end of the battery Bat is electrically connected with a power supply port VDD of the control unit U, and the other end of the battery Bat is electrically connected with a ground port GND of the control unit U; when a user inserts the atomizing assembly 12 into the control assembly 11, the control assembly 11 is connected to the atomizing assembly 12, one end of the heating resistor R is electrically connected to the atomizing port AT of the control unit U, and the other end of the heating resistor R is electrically connected to the ground port GND of the control unit U.

In the process of using the atomization device, a user can send an instruction through a breathing action performed on the atomization device or a key action performed on a shell of the atomization device, and then the control unit U sends a resistance control signal in response to the instruction so as to control the on-off of the current on the heating resistor R. When current flows through the heating resistor R, the temperature of the heating resistor R can rise rapidly, so that the substance to be atomized is vaporized, and the atomization effect is achieved; when no current flows through the heating resistor R, the heating resistor R cannot vaporize the substance to be atomized.

In the prior art, the communication of the atomization device is unidirectional, that is, the control unit of the control assembly controls the on-off of the current on the heating resistor through the resistor control signal, but cannot acquire whether the atomization assembly is a normal product. Thus, the control unit cannot know whether the issued control resistance signal is valid.

In the embodiment of the application, the atomization assembly is verified through the bidirectional communication between the control assembly and the atomization assembly. Therefore, the problem of lower safety caused by using a fake atomization component in the prior art is solved.

The technical solutions of the present application will be described in detail below with reference to specific embodiments and accompanying drawings.

Fig. 2 is a schematic circuit diagram of an atomization device according to an embodiment of the present application, where, as shown in fig. 2, the atomization device includes: the control assembly 21 and the atomization assembly 22 are detachably connected.

The control assembly 21 comprises a main control unit U1, wherein the main control unit is provided with an atomizer port AT, a check port PWM and a ground port GND; the atomizing assembly 22 includes a slave control unit U2 and a heat-generating resistor R1, the slave control unit U2 is provided with a first connection port RP electrically connected to one end of the heat-generating resistor R1, a second connection port RM electrically connected to the other end of the heat-generating resistor R1, and a response port RU. Illustratively, the heating resistor R1 may be a resistance wire.

As shown in fig. 2, when the atomizing assembly 22 is connected to the control assembly 21, the first connection port RP of the slave control unit U2 is electrically connected to the atomizer port AT of the master control unit U1, the second connection port RM of the slave control unit U2 is electrically connected to the ground port GND of the master control unit U1, and the response port RU of the slave control unit U2 is electrically connected to the check port PWM of the master control unit U1. AT this time, the master control unit U1 is configured to send the identification code to the slave control unit U2 through the nebulizer port AT, obtain a response condition of the slave control unit 22 to the identification code through the verification port PWM, verify the nebulizer assembly 22 according to the response condition to obtain a verification result, and control the nebulizer port AT to perform signal control on the heating resistor R1 according to the verification result.

It will be appreciated that the identification code described above may be formed by combining a series of specific high and low level signals. The voltage of the low level signal is not 0, so that the voltage of the atomizer port AT is ensured to maintain the power supply of the slave control unit U2. For example, if the voltage AT the nebulizer port AT is greater than 2.5V, this corresponds to a high level signal; if the voltage AT the port AT of the nebulizer is less than or equal to 2.5V and greater than 0V, it is a low level signal. The above examples are merely illustrative, and the present application is not limited thereto.

It should also be understood that the response condition of the slave control unit 22 to the identification code may be implemented by the response port RU of the slave control unit 22, i.e. a specific series of high and low level signals may be transmitted through the response port RU.

It should also be appreciated that to facilitate receipt of the complete identification code from the control unit U2, the master control unit U1 may provide a start signal and a stop signal for the identification code. In this way, the slave control unit U2 starts collecting the identification code when detecting the start signal, and ends collecting the identification code when detecting the end signal.

It will also be appreciated that the master control unit U1 will need to continue to output a turn-on signal for a period of time after sending the completion identification code through the nebulizer port AT to enable continued power to the slave control unit U2 so that the slave control unit U2 can return a response code. The conducting signal may be a signal with a voltage greater than a certain value.

Alternatively, the main control unit U1 may be the control unit U in fig. 1, and the present application is not limited in this respect.

The verification result of the atomizing assembly 22 referred to in this application may include: an atomizing assembly may be used or an atomizing assembly may not be used.

It should be appreciated that since the legacy nebulizer kit does not have the function of sending a response code, the legacy nebulizer kit is verified as a non-usable nebulizer kit. And the response codes in some fake atomization assemblies are not legal preset codes, so that the corresponding verification results of the fake atomization assemblies are unavailable atomization assemblies.

Optionally, the main control unit U1 is further configured to verify the atomizing assembly 22 based on the response code to obtain a verification result when the response condition includes detection of the response code through the verification port PWM; alternatively, when the response condition includes no response code detected through the verification port PWM, the verification result of the atomizing assembly 22 is determined to be an unavailable atomizing assembly.

Wherein the main control unit U1 verifying the atomization assembly based on the response code may further include: when the main control unit U1 determines that the response code is the preset code, it determines that the verification result of the atomizing assembly 22 is an available atomizing assembly (i.e., a normal atomizing assembly produced by a normal manufacturer); and when the response code is determined not to be the preset code, determining that the verification result of the atomization assembly is the unavailable atomization assembly.

It will be appreciated that for a regular nebulisation assembly, the corresponding slave control unit has pre-stored therein a response code and an identification code. In this way, the slave control unit transmits the response code in case of detecting the identification code. In order to avoid the theft of the response code and the identification code in the regular atomization assembly, the response code and the identification code in the regular atomization assembly can be periodically updated (for example, every 6 months), and the identification code and the preset code stored in the control assembly also need to be updated, so that the safety of verification is improved to a certain extent.

It should be noted that the verification process is completed within a very short time (e.g., milliseconds) when the atomizing assembly 22 is inserted into the control assembly 21, and therefore has no influence on the normal use experience of the user. And through the verification of the atomization component, the atomization component used by the user is guaranteed to be a product authenticated by a manufacturer, so that the use experience and the use safety of the user are guaranteed.

In some embodiments, the main control unit U1 is further configured to control the nebulizer port AT to output a signal to the heating resistor R1 when the available nebulizer assembly is determined as a result of the verification of the nebulizer assembly 22, so as to vaporize the substance to be nebulized in the nebulizer assembly 22; and when the verification result of the atomization assembly 22 is determined to be an unavailable atomization assembly, controlling the port AT of the atomizer to carry out signal cutoff on the heating resistor R1.

In other embodiments, when the response condition includes that the response code is not detected through the verification port PWM, the main control unit U1 is configured to detect whether the nebulizer assembly 22 is reinserted into the control assembly 21, and if reinsertion is detected, the nebulizer assembly 22 may be verified again to obtain the verification result; if no reinsertion is detected, the main control unit U1 determines that the verification of the atomization assembly 22 is an unavailable atomization assembly and controls the nebulizer port AT to signal-disable the atomization assembly 22.

In still other embodiments, when the response condition includes that the response code is detected through the check port PWM, and the response code is not the preset code, the main control unit U1 is configured to detect whether the nebulizer assembly 22 is reinserted into the control assembly 21, and if reinsertion is detected, the nebulizer assembly 22 may be rechecked to obtain the check result; if no reinsertion is detected, the main control unit U1 determines that the verification of the atomization assembly 22 is an unavailable atomization assembly and controls the nebulizer port AT to signal-disable the atomization assembly 22.

If the atomization assembly 22 is a normal atomization assembly, but the atomization assembly 22 falls off for a short time in the connection process, the voltage value detected by the atomizer port AT in the period of falling off is the second value, and a response code error is caused. Therefore, based on the situation, in still other embodiments, when it is determined that the verification result of the atomizing assembly 22 is an unavailable atomizing assembly, and the verification result is the result of the first verification of the atomizing assembly 22 and the control assembly 21 as an unavailable atomizing assembly in the current connection process, the main control unit U1 is further configured to resend the identification code, perform secondary verification on the atomizing assembly 22 based on the response condition of the atomizing assembly 22 to the resent identification code, and control the atomizer port AT to perform signal control on the heating resistor R1 according to the secondary verification result. Therefore, in order to avoid misjudgment of the unavailable atomization assembly, the atomization assembly with the first verification result as the unavailable atomization assembly can be subjected to secondary verification, and therefore accuracy of the verification result is improved.

Similarly, when the secondary verification result includes that the atomization assembly 22 is an available atomization assembly, the main control unit U1 controls the atomizer port AT to output a signal to the heating resistor R1; and under the condition that the secondary verification result includes that the atomization assembly 22 is an unavailable atomization assembly, the main control unit U1 controls the atomizer port AT to cut off the signal of the heating resistor R1.

It should be noted that, in the process of controlling the atomizer port AT to output a signal to the heating resistor R1 by the main control unit U1, the on-off time of the heating resistor R1 can be controlled to meet the usage habit of the user. For example, firing resistor R1 may be controlled to be on for a period of time continuously, and firing resistor R1 may be controlled to be off for a period of time, which may be cycled sequentially.

In conclusion, atomizing device's atomizing subassembly can receive control assembly's on-off instruction, and control assembly also can acquire atomizing subassembly's response situation simultaneously, and through the two-way communication between atomizing subassembly and the control assembly, can realize carrying out the check-up to atomizing subassembly like this, avoids using the lower problem of fake atomizing subassembly cause the security to can reduce the harm such as economy, reputation that cause the trade company, also reduce the harm that causes user's health.

In addition, the external connection mode between control assembly and the atomizing subassembly does not change in this application compared with prior art, so need not to change atomizing device's structure, can process atomizing device in this application through current atomizing device shell mould, practiced thrift mould development time and cost.

In some embodiments of the present application, if the atomization device in the present application does not support power supply reverse connection, during the process of inserting the atomization assembly 22 into the control assembly 21, a user needs to identify two connection ports (i.e., the first connection port and the second connection port) of the atomization assembly 22, insert the first connection port RP into the atomizer port AT, and insert the second connection port RM into the ground port GND, so as to avoid the occurrence of power supply reverse connection.

In other alternative embodiments of the present application, power supply reversal is unavoidable and can cause damage to the circuit. The atomization assembly in the embodiment of the application comprises the heating resistor R1 and the slave control unit U2, and the resistor device has no positive and negative electrodes, so that the circuit cannot be damaged. In this way, the present application can support the setting of the positive and negative connections by the slave control unit U2.

Optionally, the slave control unit U2 is configured to obtain a first voltage AT the first connection port RP and a second voltage AT the second connection port RM, respectively, and control the first connection port RP of the slave control unit U2 to be electrically connected to the nebulizer port AT of the master control unit U1 and the second connection port RM of the slave control unit U2 to be electrically connected to the ground port GND of the master control unit U1 when the first voltage is greater than the second voltage. It can be seen that by comparing the voltages AT the two connection ports of the slave control unit U2, port connection can be flexibly performed according to the comparison result (i.e., the connection port with the higher voltage can be connected to the nebulizer port AT, and the connection port with the lower voltage can be connected to the ground port GND), and positive and negative connection of the power supply is realized.

Alternatively, when the above-mentioned first voltage is less than the second voltage, the second connection port RM of the slave control unit U2 is controlled to be electrically connected to the nebulizer port AT of the master control unit U1, and the first connection port RP of the slave control unit U2 is electrically connected to the ground port GND of the master control unit U1.

For example, the slave control unit U2 may comprise at least a comparator, such that the first voltage at the first connection port RP and the second voltage at the second connection port RM are compared by the comparator.

In summary, since the heat-generating resistor belongs to the resistor device and the slave control unit is designed to prevent reverse connection, the first connection port and the second connection port of the slave control unit can be used interchangeably, i.e. the slave control unit has the characteristic of bidirectional conduction. Therefore, in the process of installing the atomization assembly, the difference of the anode and the cathode does not exist, and the use safety and reliability are effectively ensured.

In some optional embodiments of the present application, the master control unit U1 is further configured to send a control signal to the slave control unit U2 through the verification port PWM when it is determined that the verification result of the atomization assembly 22 is an available atomization assembly, acquire the state information of the heat-generating resistor R1 acquired by the slave control unit U2 based on the control signal, and control the atomizer port AT to perform signal control on the heat-generating resistor R1 according to the state information.

The state information includes information of a voltage difference corresponding to two ends of the heating resistor R1 and/or information of a current of the heating resistor R1.

It can be understood that the check port PWM can periodically send the control signal to the slave control unit U2, so as to avoid the problem of large power consumption caused by sending the control signal in real time.

It should also be understood that when the substance to be atomized in the atomizing assembly 22 is exhausted, since the heating resistor R1 is no longer immersed in the substance to be atomized, there may be an abnormality (e.g., an abnormal rise in temperature, etc.) in the temperature of the heating resistor R1, which may cause damage to the atomizing device and even endanger the personal safety of the user, so that it is necessary to turn off the output of the heating resistor R1 in time and prompt the user to replace the atomizing assembly 22, thereby ensuring the user experience and safety.

Considering that the temperature of the heat-generating resistor R1 when the substance to be atomized is consumed is different from the temperature of the heat-generating resistor R1 when the substance to be atomized is not consumed, and there is a correlation between the resistance value of the heat-generating resistor R1 and the temperature of the heat-generating resistor R1. Therefore, the present application can determine whether the heating resistor R1 is in a substance to be atomized depletion state or in a substance to be atomized non-depletion state by detecting the corresponding differential pressure information at the two ends of the heating resistor R1 and/or the current information of the heating resistor R1. Thus, the main control unit U1 is further used to determine the current state of the heating resistor R1 according to the state information, and control the nebulizer port AT to signal control the heating resistor R1 based on the current state. When the heating resistor R1 is in a substance depletion state to be atomized, the main control unit U1 controls the atomizer port AT to cut off the signal of the heating resistor R1; when the heating resistor R1 is in a non-exhaustion state of the substance to be atomized, the main control unit U1 controls the atomizer port AT to output a signal to the heating resistor R1.

For example, when the heating resistor R1 is in a substance depletion state to be atomized, the voltage difference information corresponding to the two ends of the heating resistor R1 is in a first voltage difference range, and the current information corresponding to the heating resistor R1 is in a first current range; when the heating resistor R1 is in the non-exhaustion state of the substance to be atomized, the differential pressure information corresponding to the two ends of the heating resistor R1 is in the second differential pressure range, and the current information corresponding to the heating resistor R1 is in the second current range.

It can be understood that the above-mentioned exhaustion state of the substance to be atomized represents a state where the current capacity of the substance to be atomized in the liquid storage chamber is less than or equal to the preset capacity.

Therefore, in the process that the user normally uses the atomization device, the slave control unit can monitor the current state of the heating resistor at the same time, the heating resistor is not required to be powered on in a suspended mode, and the use experience of the user is guaranteed. Meanwhile, the slave control unit is closer to the heating resistor in physical connection, so that the accuracy of state information is ensured to a certain extent.

Fig. 3 is a schematic circuit diagram of an atomizer according to the embodiment shown in fig. 2. As shown in fig. 3, the control assembly 21 further includes: the battery Bat and the pull-up resistor R2, one end of the battery Bat is electrically connected with the power supply port VDD of the main control unit U1, and the other end of the battery Bat is electrically connected with the ground port GND of the main control unit U1; one end of the pull-up resistor R2 is electrically connected to the power supply port VDD, and the other end of the pull-up resistor R2 is electrically connected to the nebulizer port AT. The battery Bat supplies power to the entire circuit of the atomizer.

The pull-up resistor R2 may be a device inside the main control unit U1, or may be a device provided outside the main control unit U1. The battery Bat may be a lithium-ion battery or a lithium-ion battery, and the present application is not limited thereto.

In the embodiment of the present application, the main control unit U1 is further configured to determine that the control assembly 21 is not connected to the atomizing assembly 22 when detecting that a difference between the voltage of the battery Bat and the voltage of the atomizer port AT is smaller than a preset threshold AT the time of pulling up the pull-up resistor R2; alternatively, when the voltage AT the nebulizer port AT is detected to be within the preset value range AT the time of pulling up the pull-up resistor R2, it is determined that the control assembly 21 is connected to the nebulizing assembly 22 (i.e., it is equivalent to the nebulizer assembly 22 being inserted into the control assembly 21 normally).

It is understood that the disconnection of the control assembly 21 from the atomizing assembly 22 can be understood as: the control module 21 is not inserted with the atomizing assembly 22 or the atomizing assembly 22 is not normally inserted into the control module 21. In this case, foreign objects may be present AT the connection ports (e.g., the nebulizer port AT, the ground port GND, the first connection port RP, the second connection port RM, etc.), or a breathing action performed on the nebulizer device may cause the nebulizer assembly 22 to be inserted into the control assembly 21 improperly.

It will be appreciated that the present application may periodically pull up on the nebulizer port AT through pull-up resistor R2. Since the resistance of pull-up resistor R2 (e.g., 10k Ω) is generally large, while the resistance of heat-generating resistor R1 (e.g., 1 Ω) is generally small. Thus, when control unit 21 and atomization unit 22 are not connected, the voltage AT port AT is equal to or close to the voltage of battery BAT, so that the predetermined threshold may be a value between [0V, 0.7V ]; when the control unit 21 is connected to the atomizing unit 22, the voltage AT the atomizer port AT is about 0V, so the predetermined value range can be [0V, 0.5V ], etc.

It should also be appreciated that the main control unit U1 in the embodiments of the present application may also send the assembly detection signal AT a low frequency (e.g., 100Hz) through the nebulizer port AT, avoiding real-time detection of the connection between the nebulizer assembly and the control assembly.

It should be noted that the main control unit U1 can control the control module 21 to be in a standby state when the control module 21 is not connected to the atomizing module 22. In addition, when the control module 21 is in the standby state, whether the control module 21 is connected with the atomizing module 22 or not can be periodically detected (for example, at the time of pulling up the pull-up resistor R2), so that the power consumption of the control module 21 is reduced.

Fig. 4 is a schematic circuit diagram of an atomizer device based on the embodiment shown in fig. 3. As shown in fig. 4, the control assembly 21 further includes: indicator circuit route 1.

The indicator light circuit route1 comprises an indicator light L1; one end of the indicator lamp L1 is electrically connected to the indicator lamp port LED of the main control unit U1, and the other end of the indicator lamp L1 is electrically connected to the ground port GND of the main control unit U1. For example, the indicator light L1 may be an LED (light emitting diode) light or the like.

In the embodiment of the present application, the main control unit U1 is further configured to control the indicator light L1 to be in an indicating state, which is used to indicate a charging state, a use state, or an abnormal connection state of the atomization device. In this way, the user may be informed of the current state of the atomizing device by controlling the indicator lamp L1.

The abnormal connection state is a state when the response code is not detected through the check port, or a state when the response code is detected through the check port and the response code is not the preset code.

For example, if the atomization device is an electronic cigarette, the use state may be a smoking state; if the atomization device is an atomization therapeutic apparatus, the using state can be a therapeutic state.

For example, the present application may indicate the respective states by different colors of the indicator light L1. For example, when the color of the indicator light L1 is red, it indicates that the atomization device is in an abnormal connection state; when the color of the indicator light L1 is green, it indicates that the atomizing device is in a charged state; when the color of the indicator lamp L1 is yellow, it indicates that the atomizing device is in use.

Further illustratively, the respective states may be indicated by different blinking frequencies of the indicator light L1. For example, when the blinking frequency of the indicator light L1 is f1, this indicates that the nebulizer is in an abnormal connection state; when the blinking frequency of the indicator light L1 is f2, it indicates that the atomizer is in a charged state; the indicator light L1 has a blinking frequency of f3, which indicates that the atomizing device is in use, f1 > f2 > f3, and so on, and the above examples are only illustrative, and the present application is not limited thereto.

Of course, the indicator light may also indicate a substance exhaustion state or a low-power state of the atomization device, where the low-power state indicates a state where the current power of the battery is less than or equal to the preset power. The type of indication by the indicator light is not particularly limited.

Fig. 5 is a schematic circuit diagram of an atomizer device based on the embodiment shown in fig. 3. As shown in fig. 5, the control assembly 21 further includes: switch circuit route 2.

The switch circuit route2 comprises a microphone switch K1; one end of the microphone switch K1 is electrically connected to the switch port SW of the master control unit U1, and the other end of the microphone switch K1 is electrically connected to the ground port GND of the master control unit U1.

In the embodiment of the application, the main control unit U1 is configured to control the nebulizer port AT to output a signal to the heating resistor R1 based on the breathing parameter detected by the microphone switch K1; the breathing parameters include at least one of breathing strength and breathing motion (i.e., expiration or inspiration).

For example, if the atomization device is an electronic cigarette, the breathing parameter may be a smoking parameter, the breathing effort corresponds to a smoking effort, and the breathing action corresponds to a smoking action; if the atomization device is an atomization therapeutic apparatus, the breathing parameter can be a therapeutic parameter, the breathing strength is corresponding to a therapeutic strength, and the breathing action is corresponding to a therapeutic action.

It will be appreciated that the microphone switch K1 may be a switch generated based on an airflow sensor. In this way, the breathing parameter can be obtained from the pressure difference detected by the airflow sensor, and the airflow sensor converts the detected pressure difference into a corresponding level signal and sends the level signal to the main control unit U1.

In some embodiments, the main control unit U1 can output different voltage signals to the heating resistor R1 according to the respiration rate; wherein, the larger the breathing force, the larger the voltage indicated by the voltage signal; the smaller the respiration rate, the smaller the voltage indicated by the voltage signal. Therefore, the corresponding voltage signal can be output to the heating resistor according to the requirements of the user, and the atomization effect is more in line with the requirements of the user.

It should also be understood that, after the main control unit U1 receives the level signal sent by the airflow sensor, the indicator light L1 in fig. 4 may also be controlled to be in the target indicating state, which is used to indicate that the atomizing device is in the use state.

Fig. 6 is a schematic circuit diagram of an atomizer device based on the embodiment shown in fig. 3. As shown in fig. 6, the control assembly 21 further includes: a regulating circuit route 3.

The voltage stabilizing circuit route3 comprises a voltage stabilizing capacitor C1; one end of the voltage-stabilizing capacitor C1 is electrically connected with one end of the battery Bat, and the other end of the voltage-stabilizing capacitor C1 is electrically connected with the other end of the battery Bat.

It is understood that the voltage of the battery is generally unstable when the battery is initially powered. Therefore, based on the charging and discharging characteristics of the capacitor, when the voltage provided by the battery Bat is higher than the voltage at two ends of the voltage stabilizing capacitor C1, the battery Bat can charge the voltage stabilizing capacitor C1, and when the voltage provided by the battery Bat is lower than the voltage at two ends of the voltage stabilizing capacitor C1, the voltage stabilizing capacitor C1 discharges. Thus, the voltage on the whole circuit is relatively smooth and has less abrupt change.

In the embodiment of the present application, the charging port VCC is configured to charge the battery Bat by electrically connecting to the Charger. As shown in fig. 7, the Charger may charge the battery Bat sequentially through the charging port VCC and the power supply port VDD.

It is understood that, during the charging process, the main control unit U1 may also determine the charging mode of different stages and perform charging according to the charging mode correspondingly. For example, if the different stages include three stages, the first stage may be a fast charging mode, the second stage is a continuous charging mode, and the third stage is a trickle charging mode. By controlling the charging mode, the battery can reach a state of electric quantity saturation, and the service life of the battery is prolonged.

In an alternative embodiment of the present application, the control assembly further comprises: a power setting circuit; the power setting circuit comprises a power setting resistor, one end of the power setting resistor is electrically connected with a power setting port of the main control unit, and the other end of the power setting resistor is electrically connected with a grounding port of the main control unit.

Therefore, the reference value of the output power of the atomization device during normal operation can be determined according to the resistance value of the power setting resistor.
