[0024] Figure 1A schematic structural diagram of an electronic atomizer of the present application is shown, Figure 2 A schematic structural diagram of a circuit assembly is shown. The following will be described in combination with Figure 1 and Figure 2 The electronic atomizer of the present application will be described in detail.

[0025] Referring to Figure 1 , the electronic atomizer 100 provided by the present application comprises:

[0026] The shell 120 forms a cavity to accommodate the atomization assembly 130 and the circuit assembly 140.

[0027] In order to facilitate the assembly of the electronic atomizer, an opening is usually provided at at least one end of the shell 120. In Figure 1 , the opening is provided at one end of the shell 120, and the opening is closed by installing the mouthpiece 110 at the opening, so as to avoid the pollution of the atomization assembly 130 and the circuit assembly 140 by the external environment. The atomization assembly 130 is usually installed at the end close to the mouthpiece 110 in the cavity and communicates with the mouthpiece 110, so as to provide an air mist suction passage when the electronic atomizer is used. In addition, the electronic atomizer 100 is also provided with an air inlet 150 (in Figure 1 , the air inlet 150 is located at the end of the shell 120 away from the mouthpiece 110) at the end of the shell 120 away from the mouthpiece 110 or on the side wall of the shell 120, for providing a passage for the gas to be inhaled into the electronic atomizer.

[0028] The collection unit 121 is arranged on the side wall of the shell 120. The collection unit 121 is used to collect identity information. The identity information includes the holder information collected when the electronic atomizer is used for the first time, and the user information collected in subsequent use. The collection unit 121 can use any biometric collection unit, such as a commonly used biometric sensing and collecting device, for example, a fingerprint recognizer, a face recognizer, a voiceprint recognizer, etc.

[0029] The atomization assembly 130 is located in the cavity and is usually located at the end close to the mouthpiece 110 in the cavity. The atomization assembly 130 comprises a liquid storage tank (not shown in the figure) and a heating module 131. The liquid storage tank is used to store the liquid substrate. The heating module 131 is powered to heat at least part of the liquid substrate to generate the air mist for the user to inhale.

[0030] The circuit assembly 140 is located in the cavity and is usually located at the end away from the mouthpiece 110 in the cavity. It is used to provide the electrical energy required for the operation of the electronic atomizer 100 and to control the operation of the electronic atomizer 100.

[0031] In particular, referring to Figure 2The circuit assembly 140 comprises: an information processing circuit 141, a control module 142, an airflow detection module 143, a power management module 144, and a dynamic monitoring module 145.

[0032] The power management module 144 is configured to provide the power required for the electronic atomizer to work. Although not fully shown in the figure, it should be understood that the power management module 144 is electrically connected to other modules in the circuit assembly 140, as well as the collection unit 121, the state indication unit 122 (to be introduced below), and the atomization assembly 130.

[0033] In some embodiments, the power management module 144 includes a rechargeable battery, for example, to provide the power, and thus a charging port connected to the rechargeable battery is further provided on the side wall of the housing 120.

[0034] The information processing circuit 141 is connected to the collection unit 121, and is configured to receive and process the identity information collected by the collection unit 121. Specifically, the information processing circuit 141 comprises:

[0035] A filter-amplification sub-circuit 141a is configured to filter and amplify the analog signal representing the identity information.

[0036] An analog-to-digital conversion sub-circuit (ADC) 141b is connected to the filter-amplification sub-circuit 141a, and is configured to convert the filtered and amplified analog signal into a digital signal.

[0037] In some embodiments, especially when collecting the holder information, it is necessary to collect the same biometric feature multiple times to obtain the complete information of the biometric feature. Thus, the information processing circuit 141 further comprises an information synthesis sub-circuit 141c. The information synthesis sub-circuit 141c is connected to the analog-to-digital conversion sub-circuit 141b, and is configured to synthesize multiple digital signals obtained by multiple collections of the same biometric feature to obtain the corresponding identity information. For example, the collection unit 121 is a fingerprint identifier, and three times of pressing the same fingerprint are required when collecting the holder information. Then, the information synthesis circuit 141c is configured to synthesize the digital signals obtained by the three times of collection to obtain the complete identity information corresponding to the fingerprint.

[0038] It should be understood that, in the prior art, the collection of identity information is a relatively mature technology, and thus the collection unit 121 and the information processing unit 141 described above can be implemented by corresponding circuits in the prior art.

[0039] The control module 142 is configured to store the owner information collected when the electronic atomizer 100 is used for the first time, and verify the user information collected in the subsequent use. The control module 142 comprises, for example, a memory and a processing chip. The memory is configured to store the owner information. The processing chip comprises, for example, an ASIC chip (Application-Specific Integrated Circuit) or an MCU chip (Microcontroller Unit) or other mature processor chip in the prior art, so as to realize the corresponding identity verification function. It should be understood that, based on the continuous development of the identity recognition technology, the related technology for realizing the identity verification function is gradually mature, and thus the processing chip can use any recognition method in the prior art to realize the identity recognition. For example, in some embodiments, when the overlap degree of the owner information and the identity information of the user information reaches a preset percentage (for example, 80%), it is determined that the owner information is consistent with the user information. For another example, when the area ratio of the collected user information to the area of the collection window of the collection unit 121 reaches a preset percentage (for example, 80%), it is determined that the user information is valid information and is compared with the owner information, so as to avoid the calculation overhead caused by the false touch.

[0040] In some embodiments, the control module 142 controls the power management module 144 to supply power to the atomization assembly 130 when the user information is consistent with the owner information. In some other embodiments, since the electronic atomizer is small in size, the power that can be provided by the electronic atomizer is also very limited. Therefore, in the preferred embodiments, the control module 142 controls the power management module 144 to supply power to the atomization assembly 130 in combination with the gas inhalation condition and the identity information verification condition.

[0041] Specifically, the circuit assembly 140 further comprises a gas flow detection module 143 configured to detect the gas flow and provide an effective level of the first control signal when the gas flow is inhaled into the electronic atomizer 100. For example, the gas flow detection module 143 comprises, for example, a parallel-plate capacitor, and the distance between the two plates of the parallel-plate capacitor changes due to the gas flow pressure when the gas is inhaled, so that the level of the first control signal is an effective level. The control module 142 controls the power management module 144 to supply power to the atomization assembly 130 when the identity information verification is passed and the effective level of the first control signal is received.

[0042] The combination of the first control signal and the identity information verification condition is realized, for example, by a logic AND circuit, or can be directly processed by the processing chip, and the present application does not make too many limitations.

[0043] Through the double control of the gas flow detection and the identity verification, the power consumption is more conducive to saving, so as to improve the endurance time of the electronic atomizer.

[0044] The dynamic monitoring module 145 is connected with the atomization assembly 130, and is configured to monitor the power supply state of the atomization assembly 130. In order to enable the user to perceive the power supply state of the atomization assembly 130, the state indication unit 122 is further arranged on the side wall of the shell 120. The state indication unit 122 is connected with the dynamic monitoring module 145 and is controlled by the dynamic monitoring module 145 to display the power supply state of the atomization assembly 130. For example, the state indication unit 122 is an indicator light or a vibration motor. When the atomization assembly 130 is powered, the indicator light is lit or the vibration motor is vibrated; when the atomization assembly 130 is not powered, the indicator light is extinguished or the vibration motor is not vibrated.

[0045] Further, in some embodiments, the dynamic monitoring module 145 is further connected with the control module 142, and feeds back the monitoring information characterizing the power supply state of the atomization assembly to the control module 142, so as to realize the control-monitoring closed loop of the atomization assembly 130. The control module 142 can also control the power supply state of the atomization assembly according to the monitoring information of the atomization assembly 130, and control the power management module 144 to control the power supply amount to the atomization assembly 130 or stop the power supply to the atomization assembly 130. For example, when the power supply frequency of the atomization assembly 130 exceeds the preset frequency, the single-time power supply amount is increased to increase the power of the electronic atomizer, so as to improve the user experience. For another example, when the single-time power supply time length of the atomization assembly 130 exceeds the preset time length, the control power management module 144 stops the power supply, so as to avoid the waste of electric energy caused by the misoperation. The above functions can be realized by a timer circuit or a counter circuit, or can be directly judged by a processing chip, and the present application does not make too many limitations.

[0046] According to the electronic atomizer provided in the present application, the holder information is collected and stored when the electronic atomizer is used for the first time by the collection unit and the circuit components inside the electronic atomizer, and the user information is verified according to the holder information in each subsequent use, so that the identity verification can be realized without communication with the outside world, thereby avoiding the cross use of the electronic atomizer. At the same time, the atomization assembly is powered only when the verification is passed and the airflow passes, which is beneficial to save electric energy.

[0047] In accordance with the embodiments of the present application as described above, these embodiments do not describe all the details, nor limit the present application to the specific embodiments. Obviously, many modifications and variations can be made according to the above description. The present application selects and specifically describes these embodiments in order to better explain the principles and practical applications of the present application, so that those skilled in the art can well utilize the present application and make modifications based on the present application. The protection scope of the present application should be subject to the scope defined by the claims of the present application.
