detailed description

The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

Example 1

As shown in FIG. 1, FIG. 3 and FIG. 4, an electronic cigarette includes an atomizer including a liquid storage device and an atomizing element 10, and the electronic cigarette further includes a driving device 16 and a power supply device. The drive device 16 is for providing a motive fluid having a driving force. In this embodiment, the driving device 16 is an air pump, and the power fluid supplied is a gas. The liquid storage device supplies the liquid smoke to the atomizing element 10 under the driving of the power fluid of the driving device 16, and the atomizing element 10 atomizes the supplied liquid smoke into smoke under the electric driving of the power supply device for the user. use. The liquid storage device may be disposable or refillable. The drive device 16 can be of the manual type or of the electric type. The atomizing element 10 may be one or a combination of at least two of a resistive heating element, an ultrasonic atomizing device, and an electromagnetic induction heating device.

The liquid storage device includes a casing 1 for containing the liquid smoke, and the casing 1 is provided with an inlet 15 and an opening 14 communicating with the atomizing element 10. The introduction port 15 cooperates with the driving device 16, and the driving device 16 is configured to supply a gas having a driving force into the casing 1 through the inlet port 15 to press the smoke liquid in the casing 1 so that the smoke liquid in the casing 1 is pressed The smoke liquid flows from the opening 14 to the atomizing element 10. It will be appreciated that it takes a certain amount of time for gas to enter the outer casing 1 through the inlet 15 until the liquid smoke flows out of the opening 14 under the pressure of the gas. If the user activates the atomizing element 10 without the smoke liquid or the smoke liquid on the atomizing element 10, the atomizing element 10 may be caused to dry. Therefore, the user needs to activate the atomizing element 10 in the case where the liquid smoke has flowed out of the opening 14, thereby reducing the possibility of dry burning.

1 and 3, in order to know the time when the liquid smoke starts to flow out from the opening 14, the liquid storage device further includes a pressure sensor 2 and an automatic reset valve 3, the power supply device including a power source 7 and a controller 8, the electrons The smoke also includes a reminder device 9. The controller 8 is electrically connected to the power source 7, the atomizing element 10, the pressure sensor 2, and the reminding device 9, respectively. The automatic reset valve 3 cooperates with an opening 14, which is capable of opening the opening 14 under the action of an external force and automatically closing the opening 14 after the external force is removed. When the gas enters the outer casing 1, pressure is generated to the liquid smoke, which in turn exerts pressure on the automatic reset valve 3. As the amount of gas entering the outer casing 1 is continuously increased, the pressure of the gas against the liquid smoke is continuously increased, and accordingly, the pressure of the liquid to the automatic reset valve 3 is also continuously increased. The pressure of the liquid to the automatic reset valve 3 is so large that the liquid smoke flows out of the opening 14 when the automatic reset valve 3 is opened. That is to say, after the self-driving device 16 is started, the gas enters the outer casing 1 so that the pressure inside the outer casing 1 is continuously increased. When the pressure is increased to a certain value, the pressure of the liquid smoke to the automatic reset valve 3 can be automatically opened. Valve 3, the time at which the pressure reaches this value is the time at which the liquid smoke flows out of the opening 14. This value can be named as a first threshold, which can be obtained by detection or calculation and stored in advance in memory. The memory may be disposed within the electronic cigarette or may be disposed in an electronic device (e.g., a smart phone) that is communicable with the electronic cigarette. The pressure sensor 2 is disposed in the outer casing 1. The pressure sensor 2 is configured to sense the pressure of the inner cavity of the outer casing 1 and feed back to the controller 8, and the automatic reset valve 3 is used to control the outer casing 1. The cavity for storing the liquid smoke is connected or disconnected from the outside, and the controller 8 compares the pressure of the inner cavity of the outer casing 1 fed back by the pressure sensor 2 with a first threshold value, when the inner cavity of the outer casing 1 When the pressure reaches the preset first threshold, it indicates that the pressure of the smoke liquid on the automatic reset valve 3 is just such that the automatic reset valve 3 is opened for the smoke liquid in the outer casing 1 to flow out. At this time, the control The device 8 controls the reminding device 9 to issue a first message for reminding the user that the liquid smoke begins to flow out of the liquid storage device. The reminding device 9 may be at least one of a vibration device, an indicator light, a display device, and a voice broadcast device.

Since the liquid smoke and the pressure sensor 2 are both housed in the outer casing 1, in order to prevent the smoke liquid from affecting the pressure sensor 2, the outer casing 1 is formed with a main chamber 11 and a sub-cavity 12 for containing the liquid smoke. The pressure sensor 2 is disposed in the sub-cavity 12, and the introduction port 15 is in communication with the sub-cavity 12. After the gas enters the sub-chamber 12 from the introduction port 15, the sub-chamber 12 enters the main chamber 11 to press the smoke liquid. The opening 14 is in communication with the main chamber 11 and the automatic reset valve 3 cooperates with the opening 14 for opening or closing the opening 14. In order to allow the gas to smoothly enter the main chamber 11, and the liquid smoke in the main chamber 11 does not flow into the sub-chamber 12, a selective permeation membrane 13 is disposed between the main chamber 11 and the sub-chamber 12, and the selective permeation is provided. The membrane 13 is used for the passage of gas from the air supply pump and serves to block leakage of the smoke liquid. In the present example, the selective permeable membrane 13 is a polytetrafluoroethylene membrane.

Example 2

As shown in FIG. 2, another liquid storage device is provided in the embodiment. The outer casing 1 is provided with a liquid storage bag 4 for containing the liquid smoke, and the automatic reset valve 3 is used for The smoke liquid in the liquid storage bag 4 is controlled to be in fluid communication with or disconnected from the outside, and the automatic reset valve 3 is opened for the outflow of the smoke liquid in the liquid storage bag 4. The inner cavity of the reservoir 4 serves as a main chamber, and a gap between the outer casing 1 and the reservoir 4 serves as a sub-cavity.

The housing 1 is provided with an opening 14 communicating with the inner cavity of the reservoir 4, the liquid storage device further comprising a sealing member, the sealing member comprising a sealing plug 51 and a fastening cover 52, the sealing plug 51 being disposed on The sealing cover 52 is disposed on the outer side of the sealing plug 51 for fixing the sealing plug 51. The sealing plug 51 is provided with a liquid smoke passage communicating with the opening 14. The automatic reset valve 3 is disposed in the smoke liquid passage. The reservoir 4 is made of a soft material. When the driving device supplies the motive fluid into the outer casing 1 through the inlet 15, the motive fluid compresses the reservoir 4, and the reservoir 4 is deformed to compress the liquid, and when the pressure of the liquid to the automatic reset valve 3 is sufficiently large, the automatic The reset valve 3 is opened, and the liquid smoke flows out from the reservoir 4.

As in the first embodiment, the present embodiment can also know the time when the smoke liquid starts to flow out by the cooperation of the pressure sensor 2 and the automatic reset valve 3. Specifically, the pressure sensor 2 detects the pressure of the inner cavity of the outer casing 1, and the time when the pressure of the inner cavity of the outer casing 1 reaches the first threshold is the time when the liquid smoke starts to flow out. Similarly, in this embodiment, the controller 8 and the reminding device 9 can also be disposed. The pressure sensor 2 detects the pressure of the inner cavity of the outer casing 1 and feeds back to the controller 8. The controller 8 presses the pressure of the inner cavity of the outer casing 1 with the preset number. A threshold is compared. When the pressure of the inner cavity of the outer casing 1 reaches the first threshold, the controller 8 controls the reminding device 9 to issue a first message for reminding the user that the liquid smoke starts to flow out of the liquid storage device. The pressure sensor 2 is disposed in the inner cavity of the outer casing 1 and outside the reservoir 4, i.e., the pressure sensor 2 is disposed in the secondary chamber.

In the present embodiment, the driving device 16 also employs an air pump, and the motive fluid is a gas. It can be understood that, in this embodiment, the power fluid does not directly press the liquid smoke, but indirectly presses the liquid liquid through the liquid storage bag 4. Therefore, other driving devices 16 such as a liquid pump may be used in this embodiment. The power fluid is a liquid. At this time, in order to prevent the power fluid from affecting the pressure sensor 2, a shield made of a selective diaphragm may be disposed outside the pressure sensor 2.

In the present embodiment, the automatic reset valve 3 includes a conduit 31 that is inserted into the smoke liquid passage of the sealing plug 51 and a valve body 32 that is movably disposed in the conduit 31. The valve body 32 can be reset by gravity. Alternatively, the automatic reset valve 3 further includes an elastic member (not shown) that cooperates with the valve body 32 such that the valve body 32 is reset by the elastic force of the elastic member.

In the second embodiment, not only the time at which the liquid smoke starts to flow out of the liquid storage device but also the time at which the liquid smoke in the liquid storage device is exhausted can be known. Specifically, after the driving device 16 is started, the gas enters the outer casing 1 so that the pressure of the inner cavity of the outer casing 1 is continuously increased. When the pressure is increased to the first threshold, the pressure of the liquid smoke to the automatic reset valve 3 can be automatically opened. Valve 3, the smoke liquid begins to flow out of the liquid storage device. Since it is necessary to maintain the open state of the automatic reset valve 3, the pressure of the inner cavity of the outer casing 1 is maintained at the first threshold during the outflow of the liquid smoke. When the liquid smoke is completely discharged, the reservoir 4 is deformed to block the opening 14 and the conduit 31, and under the blockage of the sealing plug 51, the reservoir 4 cannot be further deformed outward, thereby causing the inside of the casing 1 to become In an enclosed space, at this time, when gas is again introduced into the outer casing 1, the pressure inside the outer casing 1 is further increased. Therefore, the second threshold can be stored in advance, the pressure sensor 2 detects the pressure of the inner cavity of the outer casing 1 and feeds back to the controller 8, and the controller 8 compares the pressure of the inner cavity of the outer casing 1 with a preset second threshold when the outer casing When the pressure of the inner cavity reaches a preset second threshold, the controller 8 controls the reminding device 9 to send a second message for reminding the user to perform liquid filling or replacing the liquid storage device, wherein the second threshold is greater than the The first threshold.

In the electronic cigarettes of Examples 1 and 2, the time at which the liquid smoke starts to flow out can be obtained, and the user is notified by the reminding device 9. After the user obtains the first information from the reminder device 9, the atomizing element 10 can be activated. Of course, in order to further reduce the risk of dry burning, the user may, after obtaining the first information, cause the driving device 16 to continue to operate for a period of time, so that the aerosol liquid fully wets the atomizing element 10 and then activates the atomizing element 10.

In one embodiment, the atomizer further includes an atomizer housing (not shown), the liquid storage device and the atomizing element 10 are each housed in the nebulizer housing, and the nebulizer housing corresponds to the nebulizing element 10 A transparent viewing area is provided. When the user obtains the first information, the infiltration of the atomizing element 10 by the liquid smoke can be observed through the transparent observation area. When the user thinks that the liquid liquid has sufficiently wetted the atomizing element 10, the atomizing element 10 can be activated by itself. In addition, after the atomizing element 10 is activated, the drive unit 16 can be operated intermittently or continuously.

In another embodiment, as shown in FIG. 4, the electronic cigarette further includes a timer 6, and the driving device 16 is of an electric type. The controller 8 is electrically connected to the power source 7, the pressure sensor 20, the reminding device 9, the atomizing element 10, the timer 6, and the driving device 16, respectively. When the pressure of the inner cavity of the outer casing 1 reaches a preset first threshold, the controller 8 not only controls the reminding device 9 to issue the first information, but also controls the driving device 16 to continue working and controls the timer 6 to start timing. When the accumulated duration recorded by the timer 6 reaches a preset duration (for example, 3 s), the controller 8 controls the activation of the atomizing element 10, and the control reminding device 9 issues a third message for reminding the user that the smoke liquid has sufficiently wetted the mist. Element 10 is activated and atomizing element 10 has been activated and the user can begin pumping. Likewise, after the atomizing element 10 is activated, the drive unit 11 can be operated intermittently or continuously. In addition, when the pressure of the inner cavity of the outer casing 1 reaches a preset first threshold, the controller 8 can only control the driving device 11 to continue to operate and control the timer 6 to start timing, omitting the controller 8 to control the reminding device 9 to issue the first A step of information.

Various other changes and modifications may be made by those skilled in the art in light of the above-described technical solutions and concepts, and all such changes and modifications are intended to fall within the scope of the appended claims.
