DETAILED DESCRIPTION
According to the present disclosure, an electronic cigarette is disclosed, to allow a user to select cigarette liquid with different flavors from one electronic cigarette by using a voice.
Hereinafter technical solutions in embodiments of the present disclosure are described clearly and completely in conjunction with the drawings in the embodiments of the present disclosure. Apparently, the described embodiments are only some rather all of the embodiments of the present disclosure. Any other embodiments obtained based on the embodiments in the present disclosure by those skilled in the art without any creative work fall within the scope of protection of the present disclosure.
Reference is made to FIG. 1 which is a schematic overall structural diagram of an electronic cigarette according to an embodiment of the present disclosure.
In the embodiment, an electronic cigarette 100 includes an electronic cigarette body. A smoking end 101 is provided in the electronic cigarette body. A user can smoke through the smoking end 101.
An atomization module 102 and a battery module 103 are further provided in the electronic cigarette body.
Reference is made to FIG. 2 and FIG. 3. FIG. 2 is a schematic sectional structural diagram of the electronic cigarette shown FIG. 1. FIG. 3 is a schematic structural diagram of a circuit connection in the electronic cigarette according to an embodiment of the present disclosure.
As shown in FIG. 2 and FIG. 3, a voice recognition module 301 is further provided in the electronic cigarette body and configured to receive a voice and generate different selection signals in response to received voices. The different selection signals include a first selection signal and a second selection signal.
At least two atomization components are provided in the atomization module 102 of the electronic cigarette body, which are a first atomization component 201 and a second atomization component 203 respectively. A first liquid storage space 202 is provided in the first atomization component 201, a second liquid storage space 204 is provided in a second atomization component 203, and the first liquid storage space 202 and the second liquid storage space 204 are filled with different cigarette liquid respectively. Specifically, liquid storage cotton is provided in the first liquid storage space 202 and the second liquid storage space 204. Apparently, in practice, other liquid storage mediums may be provided in the first liquid storage space 202 and the second liquid storage space 204, which is not limited herein.
A microcontroller 302 connected to the voice recognition module 301 is further provided in the electronic cigarette body. In a case that the voice recognition module 301 generates a first selection signal in response to a received voice, the microcontroller 302 is configured to be connected to the first atomization component 201 in response to the first selection signal. In a case that the voice recognition module 301 generates a second selection signal in response to the received voice, the microcontroller 302 is configured to be connected to the second atomization component 203 in response to the second selection signal.
Apparently, in practice, more than two atomization components may be provided in the electronic cigarette body. Accordingly, the voice recognition module 301 may generate more than two selection signals in response to the received voices, where the number of the generated selection signals is equal to the number of atomization components, and there is one-to-one correspondence between the atomization components and the selection signals. Alternatively, the number of selection signals generated in response to the received voices by the voice recognition module 301 may be greater than the number of atomization components, such that each of extra selection signals corresponds to at least two atomization components. The microcontroller 302 is configured to be connected to, in response to selection signals generated by the voice recognition module 301, the atomization components corresponding to the selection signals.
An airflow sensor 303 is further provided in the electronic cigarette body, which is connected to the microcontroller 302 and configured to generate a first pulse signal. The airflow sensor generates a pulse signal when detecting that a pressure in a smog passage in the electronic cigarette body becomes lower, i.e., when a user smokes. Preferably, the airflow sensor 303 is arranged at a position close to the smoking end to improve a sensibility of sensing a smoking action of the user by the airflow sensor 303, thereby enabling the user to use the electronic cigarette more efficiently.
The battery module 103 is configured to supply power to the microcontroller 302, the airflow sensor 303, the first atomization component 201 and the second atomization component 203.
The microcontroller is further configured to receive the first pulse signal generated by the airflow sensor 303, and generate a first control signal in response to the first pulse signal. The atomization component connected to the microcontroller controls the cigarette liquid in the liquid storage space provided in the atomization component to be atomized in response to the first control signal.
For example, in a case that the voice recognition module 301 generates a first selection signal in response to a received voice, the microcontroller 302 is configured to be connected to the first atomization component 201 in response to the first selection signal. The microcontroller 302 is further configured to generate a first control signal when receiving the first pulse signal from the airflow sensor 303. The first atomization component 201 connected to the microcontroller 302 controls the cigarette liquid in the first liquid storage space to be atomized in response to the first control signal.
In a case that the voice recognition module 301 generates a second selection signal in response to the received voice, the microcontroller 302 is configured to be connected to the second atomization component 203 in response to the second selection signal. The microcontroller 302 is further configured to generate the first control signal when receiving the first pulse signal from the airflow sensor 303. The second atomization component 203 connected to the microcontroller 302 controls the cigarette liquid in the second liquid storage space to be atomized in response to the first control signal.
Preferably, the voice recognition module 301 may further generate a third selection signal in response to the received voice, and the microcontroller 302 is further configured to be connected to both the first atomization component 201 and the second atomization component 203 in response to the third selection signal. The microcontroller 302 is further configured to generate the first control signal when receiving the first pulse signal from the airflow sensor 303. The first atomization component 201 connected to the microcontroller 302 controls the cigarette liquid in the first liquid storage space to be atomized in response to the first control signal, and the second atomization component 203 connected to the microcontroller 302 controls the cigarette liquid in the second liquid storage space to be atomized in response to the first control signal. In this way, the user can take in mixed smog generated by atomizing two types of different cigarette liquid simultaneously, thereby providing smog with a third flavor for the user. Apparently, in practice, the voice recognition module 301 may not generate the third selection signal. The above contents are only exemplary and are not intended to limit.
A smog passage is provided in the electronic cigarette body for the atomized cigarette liquid to flow, to enable the user to take in the cigarette liquid flowing through the smog passage with the smoking end 101.
In the embodiment of the present disclosure, at least two atomization components are provided in the electronic cigarette body, where liquid spaces filled with different cigarette liquid are provided in different atomization components. Furthermore, the voice recognition module and the microcontroller connected to each other are further provided on the electronic cigarette, where the voice recognition module transmits different selection signals in response to the received different voices, and the microcontroller selects corresponding atomization components to work in response to the different selection signals. In this way, the user can take in cigarette liquid with different flavors from one electronic cigarette, thereby avoiding inconvenience of carrying multiple electronic cigarettes by the user. In addition, the user can select the cigarette liquid with different flavors from one electronic cigarette by using a voice, which is convenient and quick, thereby improving the user experience.
In the present disclosure, the atomization components in the atomization module 102 in the electronic cigarette body can be implemented in multiple structures. Hereinafter a specific structure of an atomization module of the electronic cigarette is described in detail in conjunction with FIG. 4. Reference is made to FIG. 4 which is a schematic sectional structural diagram of an atomization module in the electronic cigarette shown in FIG. 1 according to an embodiment.
The atomization module 102 includes a first atomization component 201 including a first heating wire component 401 and a second atomization component 203 including a second heating wire component 403.
The first heating wire component 401 of the first atomization component 201 is configured to atomize cigarette liquid in the first liquid storage space 202. Specifically, in the embodiment, the first liquid storage space 202 is around a hollow first PVC silicone fiberglass sleeving 402, a through hole is provided on the first PVC silicone fiberglass sleeving 402, and an extension direction of the through hole is perpendicular to an extension direction of the first PVC silicone fiberglass sleeving 402, such that the first heating wire component 401 can pass through the through hole and be fixed with the first heating wire component 401. In addition, both ends of the first heating wire component 401 are inserted into the first liquid storage space 202, so as to atomize the cigarette liquid in the first liquid storage space 202. Apparently, in practice, the first liquid storage space and the first heating wire component in the first atomization component may be arranged in other ways, which is not limited herein.
The second atomization component 203 has the same structure as that of the first atomization component 201. Alternatively, in practice, the second atomization component 203 may have a different structure from that of the first atomization component 201, and the second liquid storage space 204 and the second heating wire component 403 in the second atomization component 203 may have other structures, which is not limited herein.
The first liquid storage space 202 and the second liquid storage space 204 are arranged in a parallel and side by side manner in the electronic cigarette body. Two ends of the first liquid storage space 202 are respectively adjacent to two ends of the second liquid storage space 204, such that the first atomization component 201 and the second atomization component 203 are arranged in a parallel side by side in the electronic cigarette body. Furthermore, one end of each of the two atomization components is adjacent to the battery module 103.
In the embodiment, by arranging the atomization components in the atomization module 102 as above, the internal structure of the atomization module 102 is compact, thereby reducing a volume of the electronic cigarette body.
Preferably, in the embodiment, the first atomization component 201 further includes a first atomizer bracket 404, and the first liquid storage space 202 is arranged on the first atomizer bracket 404. A first thread segment 405 configured to detachably connect to the battery module 103 is provided at an end of the first atomizer bracket 404 close to the battery module 103. Specifically, the first thread segment 405 is an external thread. Accordingly, a first matching thread is provided at an end of the battery module 103 close to the first atomizer bracket 404, such that the first atomizer bracket 404 and the battery module 103 are detachably connected to each other by cooperation between the first thread segment 405 and the first matching thread. Specifically, the first matching thread is an internal thread. Apparently, in practice, the first thread segment may be an internal thread and the first matching thread may be an external thread, which is not limited herein.
Furthermore, a first atomizer electrode 406 is further provided fixedly in the first thread segment 405 on the first atomizer bracket 404. When the first atomization component 201 is connected to the battery module 103 through the thread, the first atomizer electrode 406 is connected to a battery electrode in the battery module 103, such that the battery module 103 can supply power to the first atomization component 201 when the microcontroller is connected to the first atomization component 201.
Similarly, the second atomization component 203 further includes a second atomizer bracket 407, and the second liquid storage space 204 is arranged on the second atomizer bracket 407. A second thread segment 408 configured to detachably connect to the battery module 103 is provided at an end of the second atomizer bracket 407 close to the battery module 103. Specifically, the second thread segment 408 is an external thread. Accordingly, a second matching thread is provided at an end of the battery module 103 close to the second atomizer bracket 407, such that the second atomizer bracket 407 and the battery module 103 are detachably connected to each other by cooperation between the second thread segment 408 and the second matching thread. Specifically, the second matching thread is an internal thread. Apparently, in practice, the second thread segment may be an internal thread and the second matching thread may be an external thread, which is not limited herein.
Furthermore, a second atomizer electrode 409 is further provided fixedly in the second thread segment 408 on the second atomizer bracket 407. When the second atomization component 203 is connected to the battery module 103 through the thread, the second atomizer electrode 407 is connected to a battery electrode in the battery module 103, such that the battery module 103 can supply power to the second atomization component 203 when the microcontroller 302 is connected to the second atomization component 203.
In this way, the first atomization component and the second atomization component are detachably connected to the battery module 103 through the thread segments respectively, so as to facilitate the user replacing the atomization components.
The above atomization components are described to be connected to the battery module through the thread as an example. In practice, the atomization components may be connected to the battery module in other detachable ways, such as snap connection. In this case, a connection structure on the atomizer bracket is not a thread segment but an elastic snap spring plate. Apparently, the above contents are only exemplary and are not intended to limit. Alternatively, the atomization components may even be connected to the battery module in a non-detachable manner, which is not limited herein.
In the present disclosure, the voice recognition module 301 in the electronic cigarette body can be implemented in multiple ways. Hereinafter a specific implementation of the voice recognition module 301 of the electronic cigarette is described in detail in conjunction with FIG. 5. Reference is made to FIG. 5 which is a schematic diagram of the voice recognition module 301 of the electronic cigarette shown in FIG. 1 according to an embodiment.
As shown in FIG. 5, the voice recognition module 301 includes a voice receiver 205 (see FIG. 2) and a voice recognition unit 501.
The voice receiver 205 is configured to receive a voice signal and convert the received voice signal into an electrical signal. For example, the voice receiver may be a mouthpiece. Apparently, the above example is only illustrative and is not intended to limit. Specifically, the voice receiver 205 may be located at an end of the batter module 103 away from the atomization component 102 (see FIG. 2) and is electrically connected to a battery in the battery module 103. Apparently, the above is only an example of the position of the voice receiver 205, which is not intended to limit.
The voice recognition unit 501 is configured to generate the first selection signal or the second selection signal in response to the electrical signal, and transmit the first selection signal or the second selection signal to the microcontroller 302.
In practice, one-to-one correspondence between preset electrical signals and selection signals may be set in advance for the voice recognition unit 501 in the voice recognition module 301 in factory. In use, when the user makes a voice, the voice receiver receives the voice signal, converts the voice signal into an electrical signal and transmits the electrical signal to the voice recognition unit 501. The voice recognition module 301 determines whether the electrical signal matches with one of the preset electrical signals, and generates a selection signal corresponding to the electrical signal if the electrical signal matches with one of the preset electrical signals, or generates no selection signal if the electrical signal does not match with any one of the preset electrical signals.
Apparently, in practice, the electrical signals corresponding to the selection signals in the voice recognition unit 501 may not be set in factory but is set by the user, which is not limited herein.
Preferably, a button is further provided on the electronic cigarette body and configured to control the voice receiver 205 in the voice recognition module 301 to be turned on or turned off, which is described in detail hereinafter.
Referring to FIG. 2, a button 206 configured to receive an operation instruction from the user is further provided on the battery module 103 of the electronic cigarette body, and a micro-touch switch 207 is connected to the button 206 and configured to generate a starting signal in response to the operation instruction. The micro-touch switch 207 is electrically connected to the voice receiver 205, such that the voice receiver 205 receives the voice signal in response to the starting signal.
The above arrangement may be adopted to avoid frequent misoperations due to the voice receiver being in a state of receiving the voice signal all the time, and save electric quantity of the battery module.
In the electronic cigarette according to the present disclosure, preferably, a low voltage protection module 304 (see FIG. 3) is further provided in the electronic cigarette body, and a first reminding device (not shown) connected to the low voltage protection module 304 is further provided on an external surface of the electronic cigarette body. The low voltage protection module 304 is configured to control a working state of the first reminding device. The first reminding device may be a liquid crystal screen, an LED light or a generator, which is not limited herein. For example, the first reminding device is an LED light, and the low voltage protection module 304 may control the first reminding device to light up or flicker with a certain frequency in a case that the battery electric quantity of the electronic cigarette is lower than a preset threshold.
In the electronic cigarette according to the present disclosure, preferably, an overcurrent protection module 305 (see FIG. 3) is further provided in the electronic cigarette body, and a second reminding device (not shown) connected to the overcurrent protection module 305 is further provided on an external surface of the electronic cigarette body. The overcurrent protection module 305 is configured to control a working state of the second reminding device. The second reminding device may be a liquid crystal screen, an LED light or a generator, which is not limited herein. For example, the second reminding device is an LED light, and the overcurrent protection module 305 controls the second reminding device to light up or flicker with a certain frequency in a case that a circuit of the electronic cigarette is shorted, and controls the second reminding device to be turned off in a case that the circuit of the electronic cigarette is normal.
The electronic cigarette according to the embodiments of the present disclosure is described above, and hereinafter a method for controlling atomization of an electronic cigarette is described according to an embodiment of the present disclosure. Referring to FIG. 6, according to an embodiment of the present disclosure, the method for controlling atomization of an electronic cigarette includes step 601 to step 604 in the following.
In step 601, the electronic cigarette acquires a voice signal.
In the embodiment, a voice receiver is provided on the electronic cigarette and is capable of receiving the voice signal. In addition, at least two atomization components are further provided in the electronic cigarette. Each of the atomization components is provided with a separate liquid storage space filled with different cigarette liquid.
In step 602, the electronic cigarette generates a selection signal in response to the voice signal, where different selection signals correspond to different atomization components.
The electronic cigarette may generate more than two selection signals in response to the received voices, where the number of the generated selection signals is equal to the number of atomization components provided in the electronic cigarette, and there is one-to-one correspondence between the atomization components and the selection signals. Alternatively, the number of the selection signals generated in response to the received voices by the electronic cigarette is greater than the number of the atomization components provided in the electronic cigarette, such that each of extra selection signals corresponds to at least two atomization components.
In the embodiment, not any voice signal will cause the electronic cigarette to generate a selection signal. Preset voice signals corresponding to selection signals are set in advance for the electronic cigarette. The electronic cigarette generates a corresponding selection signal in response to the received voice signal only in a case that the received voice signal is consistent with one of the preset voice signals, and generates no selection signal in a case that the received voice signal is not consistent with any of the preset voice signals.
The preset voice signals corresponding to the selection signals may be set in advance in the electronic cigarette in factory. Alternatively, the preset voice signals may be set by the user, which is not limited herein.
In step 603, the electronic cigarette selects the atomization component corresponding to the generated selection signal in response to the generated selection signal.
Correspondence between the atomization components and the selection signals is preset in the electronic cigarette. It should be noted that, in the embodiment, one selection signal may correspond to one atomization component or at least two atomization components. After the electronic cigarette generates a corresponding selection signal in response to the received voice signal, the electronic cigarette selects one or at least two atomization components corresponding to the generated selection signal in response to the selection signal, such that the one or at least two atomization components are in a state ready to work.
For example, in a circuit of the electronic cigarette, one of two electrodes in each atomization component of the electronic cigarette is connected to the battery for supplying power, and the other of the two electrodes is disconnected from the circuit and in an unconnected state. When the electronic cigarette generates a selection signal in response to the received voice signal, the electronic cigarette connects the electrode which is disconnected from the circuit in the atomization component corresponding to the selection signal to the circuit, such that the atomization component is in the state ready to work.
Preferably, the electronic cigarette includes a first atomization component and a second atomization component. The first atomization component is selected in a case that the selection signal is a first selection signal; the second atomization component is selected in a case that the selection signal is a second selection electrical signal; and both the first atomization component and the second atomization component are selected in a case that the selection signal is a third selection electrical signal. In this way, the user can take in cigarette liquid with three flavors even if only two atomization components are provided in the electronic cigarette.
In step 604, the electronic cigarette controls the selected atomization component to work when detecting that an internal pressure of the electronic cigarette changes.
When the user starts to smoke the electronic cigarette, the internal pressure of the electronic cigarette changes.
