Fig. 1 is a schematic view of an electronic atomizing device according to an exemplary embodiment of the present utility model.
As shown in fig. 1, the electronic atomizing device 100 includes an atomizer 10 (first portion) and a power supply assembly 20 (second portion), and the atomizer 10 is integrally formed with the power supply assembly 20. In other examples, it is also possible that the atomizer 10 is detachably connected to the power supply assembly 20.
The atomizer 10 includes a reservoir (not shown) for storing aerosol-forming substrate and an atomizing assembly 11, the atomizing assembly 11 atomizing the aerosol-forming substrate to form a smokable aerosol under the power provided by a power supply assembly 20.
The aerosol-forming substrate is a liquid aerosol-forming substrate, i.e. a liquid substrate.
The atomizing assembly 11 includes a heating element to heat the liquid aerosol-forming substrate to form a smokable aerosol. The heating element may be a resistive heating element, an electromagnetic induction heating element, or an infrared radiation heating element, etc. In other examples, the atomizing assembly 11 comprises an ultrasonic atomizing plate that generates high frequency oscillations to ultrasonically atomize the liquid aerosol-forming substrate to form a smokable aerosol.
The atomizing assembly 11 also includes a liquid transfer unit. The liquid transfer unit may be, for example, cotton fiber, metal fiber, ceramic fiber, glass fiber, porous ceramic, etc., and may transfer the liquid aerosol-forming substrate stored in the liquid storage chamber to the heating element or the ultrasonic atomizing sheet by capillary action.
The power supply assembly 20 includes a battery cell 21 and a circuit 22.
The battery 21 provides electrical power for operating the electronic atomizing device 100. The battery 21 may be a rechargeable battery or a disposable battery.
The circuit 22 may control the overall operation of the electronic atomizing device 100. The circuit 22 controls not only the operation of the battery 21 and the atomizing assembly 11, but also the operation of other elements in the electronic atomizing device 100.
The air outlet 12 is provided at an upper end of the electronic atomizing device 100, the air inlet 23 is provided at a lower end of the electronic atomizing device 100, and the air flow channel R1 (indicated by a broken line arrow in the drawing) extends from the air inlet 23 to the air outlet 12. Air flows into the air flow path R1 through the air inlet 12 and flows out of the air outlet 23 after flowing through the atomizing assembly 11. The positions of the air inlet 23 and the air outlet 12 are not limited to the manner shown in fig. 1, and in other examples, both the air inlet 23 and the air outlet 12 may be provided on the atomizer 10.
In a preferred implementation, the atomizing assembly 11 defines part of the gas flow channel R1. For example: a tubular atomizing assembly 11, the hollow interior of which defines a partial air flow channel R1; a plate-like atomizing member 11, one surface of which defines a part of the air flow channel R1.
The suction detector 24 is used for sensing the change of the air pressure in the air flow passage R1 to output an electric signal, i.e., to detect whether the electronic atomizing device is sucked. The suction detector 24 may be disposed in the airflow path R1 or in fluid communication with the airflow path R1. In a preferred implementation, the suction detector 24 is provided in the power supply assembly upstream of the atomizing assembly 11. The suction detector 24 preferably employs an air pressure sensor.
Fig. 2 is a schematic circuit diagram provided by a specific example of the present utility model.
As shown in fig. 2, in a specific example, the suction detector 24 (shown as U1 in the figure) includes a positive power connection terminal+, a negative power connection terminal-, and an output terminal F. Wherein the negative power connection is ground.
The first switching circuit includes a switch S2, a switching tube Q2, and a resistor R2. One end of the first switching circuit is electrically connected to a heating element (Coil in the figure), and the other end is electrically connected to the output F of the suction detector 24.
The second switching circuit includes a switch S1, a switching tube Q1, and a resistor R1. One end of the second switching circuit is electrically connected to the positive electrode of the battery cell 21 (BAT shown in the figure), and the other end is electrically connected to the positive power supply connection terminal +of the suction detector 24.
In this particular example, switch S1 employs a mechanical switch that can be externally manipulated or actuated, including but not limited to a rotary switch, a tactile switch, a pressure switch, a push button switch, a toggle switch, and the like. The switch tube Q1 adopts a PMOS tube. A first electrode terminal (shown as a source S in the figure) of the switching tube Q1 is electrically connected to the positive electrode of the battery cell 21, a second electrode terminal (shown as a drain D in the figure) of the switching tube Q1 is electrically connected to a positive power supply connection terminal+ of the pumping detector 24, and a control terminal of the switching tube Q1 is configured to receive a first control signal (shown as a gate G in the figure) to turn on or off the electrical connection between the battery cell 21 and the pumping detector 24. One end of the resistor R1 is electrically connected with the control end of the switching tube Q1, and the other end of the resistor R1 is electrically connected with the first electrode end of the switching tube Q1; when the switch S1 is not turned on, the resistor R1 can ensure that the switching tube Q1 is in an off-state.
One end of the switch S1 is electrically connected with the control end of the switch tube Q1, and the other end of the switch S1 is grounded. The switch S1 is used to generate a first control signal to turn on or off the electrical connection between the battery cell 21 and the suction detector 24.
In a preferred embodiment, the rated current of the switch S1 is smaller than the rated current of the switching tube Q1. Thus, the switching transistor Q1 with a large current is controlled by the switch S1 with a small current.
Similar to the switch S1, the switch Q1, the switch S2 is a mechanical switch, preferably the switch S2 is a sliding switch operable in a first position and a second position. The switch tube Q2 adopts a PMOS tube. The electrode terminal D of the switching tube Q2 is electrically connected to the heating element, the electrode terminal S of the switching tube Q2 is electrically connected to the output terminal F of the suction detector 24, and the control terminal G of the switching tube Q2 is configured to receive a second control signal to turn on or off the electrical connection between the heating element and the suction detector 24. One end of the resistor R2 is electrically connected with the control end of the switching tube Q2, and the other end of the resistor R2 is electrically connected with the electrode end D of the switching tube Q2; when the switch S2 is not turned on, the resistor R2 can ensure that the switching tube Q2 is in an off-state.
One end of the switch S2 is electrically connected with the control end G of the switch tube Q2, and the other end of the switch S2 is grounded. The switch S2 is used to generate a second control signal to turn on or off the electrical connection between the heating element and the suction detector 24.
In a preferred embodiment, the rated current of the switch S2 is smaller than the rated current of the switching tube Q2. Thus, the switching transistor Q2 of a large current is controlled by the switch S2 of a small current.
It should be noted that, the above-mentioned switching transistors Q1 and Q2 may also be other similar controllable switches, such as NMOS transistors, IGBT transistors, and so on.
The operation of the specific example circuit of fig. 2 is generally as follows:
when the toggle switch S1 is turned on, the control end of the switching tube Q1 receives a low level signal, thereby turning on the electrical connection between the core 21 and the suction detector 24. If the switch S2 is not turned on at this time, even if the electronic atomizing apparatus is suctioned (i.e., the suction detector 24 detects that the electronic atomizing apparatus is suctioned, and outputs an electrical signal through the output terminal F), the electrical connection between the heating element and the suction detector 24 is still in an off state, and therefore, the heating element is not heated by electricity.
Similarly, when toggle switch S2 is turned on, the control terminal of switch Q2 receives a low signal, thereby turning on the electrical connection between the heating element and suction detector 24. If the switch S1 is not turned on at this time, even if the electronic atomizing apparatus is suctioned (i.e., the suction detector 24 detects that the electronic atomizing apparatus is suctioned, and outputs an electrical signal through the output terminal F), the electrical connection between the electric core 21 and the suction detector 24 is still in the off state, and therefore, the heating element is not heated by electricity.
When both toggle switches S1 and S2 are turned on, the control end of the switching tube Q1 receives a low level signal, thereby turning on the electrical connection between the core 21 and the suction detector 24; the control terminal of the switching tube Q2 receives a low signal, thereby turning on the electrical connection between the heating element and the suction detector 24. When the suction detector 24 detects that the electronic atomizing device is sucked, an electric signal is output through the output end F, so that the electric connection between the electric core 21 and the heating element is conducted, and the heating element starts to generate heat by being electrified.
In summary, only when the switches S1 and S2 are turned on, the electronic atomizing device can be unlocked, so that normal suction is realized. The child generally does not consciously perform such operation, so that the electronic atomization device can be prevented from being triggered to start up by mistake, and the child is protected.
In an alternative implementation, the switches S1, S2 may also be controllable switches, such as low current MOS transistors. The control signals for switches S1, S2 may both be generated by the controller. For example: when the controller receives a first instruction, a first control signal is generated to the switch S1 so as to control the switch S1 to be conducted; when the controller receives the second instruction, a second control signal is generated to the switch S2 so as to control the switch S2 to be conducted. The first instruction and the second instruction may be implemented by different operations of the user, for example: suction, keys, etc.
In another implementation, it is also possible to eliminate the second switching circuit; that is, the positive power connection terminal+ of the suction detector 24 is electrically connected to the positive electrode of the battery cell 21 (shown as BAT in the figure). From the above analysis, it can be determined that unlocking of the electronic atomizing device can be achieved only when the switch S2 is turned on, thereby achieving normal suction. The child generally does not consciously perform such operation, so that the electronic atomization device can be prevented from being triggered to start up by mistake, and the child is protected.
In yet another implementation, the first switching circuit is implemented using a high current mechanical switch, as well as being feasible. I.e. one end of the high-current mechanical switch is electrically connected to the heating element and the other end of the high-current mechanical switch is electrically connected to the output F of the suction detector 24. Similarly, it is also possible that the second switching circuit is implemented using a high current mechanical switch.
Fig. 3 is a schematic diagram of an operation method of the electronic atomizing device according to an example of the present utility model. Reference is made to the foregoing examples for structural design of an electronic atomizing device.
As shown in fig. 3, the operation method includes:
step S11, the first switch circuit and the second switch circuit are operated to be conducted;
step S12, sucking the electronic atomizing device, so that the sucking detector controls the conduction of the electrical connection between the electric core and the heating element.
In a preferred implementation, the switch S1 is first toggled so that the control end of the switching tube Q1 receives a low level signal, thereby turning on the electrical connection between the core 21 and the suction detector 24; the switch S2 is then toggled so that the control of the switching tube Q2 receives a low signal, thereby turning on the electrical connection between the heating element and the suction detector 24.
In a preferred embodiment, the first switching circuit and the second switching circuit are both controlled to open at the end of the heating element stopping heating or pumping.
Specifically, the switch S2 may be first toggled so that the control end of the switching tube Q2 receives a high level signal, thereby disconnecting the electrical connection between the heating element and the suction detector 24; the switch S1 is then toggled so that the control of the switching tube Q1 receives a high signal, thereby breaking the electrical connection between the cell 21 and the suction detector 24.
It will be appreciated that the toggle sequence of the switches S1, S2 may not be limited.
The unlocking and locking process of the electronic atomizing device 100 is described below with reference to fig. 4:
first, it is determined whether the electronic atomizing apparatus 100 is in a locked state (step S21);
if the electronic atomizing apparatus 100 is in the locked state, the user toggles the switch S1 and the switch S2 with his/her own finger (step S22), so that the electronic atomizing apparatus is in the unlocked state (step S23).
Next, the user sucks the electronic atomizing device, the electrical connection between the heating element and the suction detector 24 is conducted, and the heating element starts to be electrically heated (step S24-step S25). During which the user may continuously aspirate the suction electronic atomizing device.
When the heating element stops heating or the suction is finished, the user again toggles the switch S1 and the switch S2 through his own fingers, so that the electronic atomizing device is in a locking state (step S26-step S28).
If it is not detected that the electronic atomizing device is suctioned, continuing the detection (step S24); or, the user toggles the switch S1 and the switch S2 again by his own finger, so that the electronic atomizing device is in a locked state (step S26-step S28).

As shown in fig. 5, the operation method includes:
step S31, a first switch circuit is operated to be conducted;
step S32, sucking the electronic atomizing device, so that the sucking detector controls the conduction of the electrical connection between the electric core and the heating element.
In a preferred embodiment, the first switching circuit is controlled to open when the heating element stops heating or the suction ends.
