The airflow switch assembly 3 can control the circuit between the battery assembly 1 and the atomizer 2 to be switched on or off under the action of airflow, so that the battery assembly 2 transmits or stops transmitting the working voltage to the atomizer 1, specifically, the airflow sensing member 33 can rotate under the action of airflow to enable the battery assembly 2 to supply power to the atomizer 1, and the airflow sensing member 33 can also reset under the action of the elastic force of the elastic component 32 to enable the battery assembly 2 to stop supplying power to the atomizer 1.

The airflow passage is a passage for airflow circulation, and the airflow passage in the electronic cigarette is a passage for communicating an air inlet of the electronic cigarette with the cigarette holder, and is used for taking out smoke generated by an atomizing head in the atomizer 1 from the cigarette holder through the airflow passage by external air so as to be sucked by a user. Both the mouthpiece and the air inlet are typically provided on the nebulizer 1, but in some possible embodiments the air inlet of the e-cigarette may also be provided on the battery assembly 2. In the present embodiment, the example in which the air inlet is provided in the atomizer 1 is described.

As shown in fig. 2, an air flow path is a schematic diagram of the atomizer 1, the air flow path is a path connecting a mouthpiece 11 of the atomizer 1 and an air inlet 12, and an air flow switch assembly 3 is disposed near the air inlet 12.

Like this, when the user uses this electron cigarette smoking, airflow switch module 3 meets the air current, and the promotion of air current is closed down, and the interconnecting link between battery pack 2 and atomizer 1 is put through, and battery pack 2 provides operating voltage for atomizer 1. When the user stops smoking, airflow switch module 3 resets, that is to say airflow switch module 3 is in the off-state, and the interconnecting link disconnection between battery pack 2 and atomizer 1, battery pack 2 stops to provide operating voltage for atomizer 1. The user finishes smoking and stops smoking through smoking and not smoking the electronic cigarette, the situation of the user is similar to that of real smoking, and the use experience of the user is greatly improved. And when the user used this electron cigarette, need not to smoke through frequently pressing mechanical switch to, avoided the condition that mechanical switch damaged, can prolong the life of electron cigarette.

The structural relationship of the components of the electronic cigarette can be as follows:

an atomizer 1 for an electronic cigarette:

as shown in fig. 2, the atomizer 1 includes not only the mouthpiece 11, but also an upper cover 13, an atomizing head 16 and a base 15, the upper cover 13 is detachably connected to the base 15, the atomizing head 16 is accommodated in an accommodating space defined by the upper cover 13 and the base 15, and the atomizing head 16 is provided with a heating element 161 for atomizing the aerosol-forming substrate to generate smoke for a user to inhale.

The electric control switch 211 is a switch for controlling the on/off of the circuit through an electric signal, and may be a Metal-Oxide-Semiconductor (MOS) transistor, a relay, a chip, or the like. When the current in the electronic cigarette is too large, the electronic control switch 211 is broken down, the circuit where the electronic control switch is located is disconnected, and the electronic cigarette stops working, so that other parts of the electronic cigarette can be protected from being damaged.

Third, about the air current switch module 3 of electron cigarette

As shown in fig. 3, the airflow switch assembly 3 further includes a fixing plate 31, the fixing plate 31 is fixed on the atomizer 1 or the battery assembly 2, and the elastic member 32 and the airflow sensing member 33 are mounted on the electronic cigarette through the fixing plate 31. It will be appreciated that the fixing plate 31 may be omitted and the resilient member 32 and the airflow sensing member 33 may be mounted directly on the e-cigarette.

The airflow sensor 33 includes a rotating shaft 331 and a blade 332, wherein the blade 332 is fixed to one end of the rotating shaft 331 by an elastic member 32, that is, the elastic member 32 is disposed between the blade 332 and the rotating shaft 331. The vane 332 is interlocked with the rotation shaft 331, and when the vane 332 rotates by the airflow, the rotation shaft 331 also rotates, and when the vane 332 is restored by the elastic force of the elastic member 32, the rotation shaft 331 also restores. The airflow sensing member 33 further includes a first conductive end 333 and a second conductive end 311 coupled to the first conductive end 333, wherein the first conductive end 333 is fixed to an end of the rotating shaft 331 opposite to the blade 332; the second conductive terminal 311 is disposed at a position of the fixed plate 31 corresponding to the first conductive terminal 333. Thus, when the rotating shaft 331 rotates, the first conductive terminal 333 can be contacted with the second conductive terminal 311, and when the rotating shaft 331 resets, the first conductive terminal 333 is separated from the second conductive terminal 311. As shown in fig. 1, the first conductive terminal 333 is electrically connected to the controller 212 of the battery assembly 2, and the second conductive terminal 311 is also electrically connected to the controller 212; when the elastic member 32 is in a natural state, as shown in fig. 3, the first conductive terminal 333 is not in contact with the second conductive terminal 311; when the blade 332 is pushed by the suction airflow to elastically deform the elastic member 32, as shown in fig. 4, the first conductive terminal 333 contacts with the second conductive terminal 311.

In an alternative embodiment, the first conductive terminal 333 may be replaced by a blade 332, in which case the blade 332 is electrically connected to the controller 212 through the elastic component 32 and the rotating shaft 331, and the second conductive terminal 311 may be replaced by a fixing plate 31, in which case the fixing plate 31 is electrically connected to the controller 212. This embodiment is not limited to this. In this embodiment, the blade 332 and the first conductive terminal 333 are located at two opposite ends of the rotating shaft 331, and the second conductive terminal 311 is disposed on the fixing plate 31.

In the present embodiment, since the airflow switch assembly 3 performs a switching function controlled by the airflow, the airflow switch assembly 3 is installed on the airflow path, and particularly, may be installed at the air inlet 12, as described above, the air inlet 12 is provided on the side wall of the upper cover 13, and thus, the fixing plate 31 of the airflow switch assembly 3 may be installed on the bottom of the upper cover 13. As shown in fig. 5, a rotation hole 312 may be formed on the fixing plate 31, and a rotation shaft 331 may be installed in the rotation hole 312 and may rotate in the rotation hole 312. A first conductive terminal 333 is disposed at an end of the rotating shaft 331 away from the air inlet 12, and a second conductive terminal 311 is disposed at a position on the fixing plate 31 corresponding to the first conductive terminal 333.

According to the structure of the airflow switch assembly 3, the mode of the airflow switch assembly 3 controlling the battery assembly 2 to supply power to the atomizer 1 is specifically as follows:

as shown in fig. 6, the airflow switch assembly 3 is electrically connected to the controller 212, and the airflow switch assembly 3 can send a closing signal to the controller 212, and the controller 212 controls the battery assembly 2 to supply power to the atomizer 1 after receiving the closing signal. As shown in fig. 7, an electrical circuit for supplying power to the atomizer 1 from the battery assembly 2 may be provided with an electronic switch 4, and the electronic switch 4 is electrically connected to the controller 212.

As shown in fig. 6, the controller 212 may be electrically connected to the airflow sensing element 33, the heating element 161, and the battery 22, respectively, and when the controller 212 detects that the first conductive terminal 333 is in contact with the second conductive terminal 311, the controller 212 controls the battery 22 to supply power to the heating element 161, and when the controller 212 detects that the first conductive terminal 333 is separated from the second conductive terminal 311, the controller 212 controls the battery 22 to stop supplying power to the heating element 161.

The specific application scenario may be: when a user smokes, first, an air flow enters into the air flow path through the air inlet 12. Then, the blade 332 drives the rotating shaft 331 to rotate under the action of the airflow, as shown in fig. 4, so that the first conductive terminal 333 contacts with the second conductive terminal 311, and the airflow switch component 3 sends a closing signal to the controller 212. Finally, after receiving the closing signal, the controller 212 controls the electronic switch 4 to close, so that a power supply line for supplying power to the atomizer 1 by the battery assembly 2 is conducted, and the battery assembly 2 supplies voltage to the atomizer 1. When the user stops smoking, the blade 332 returns to the natural state under the elasticity of the elastic component 32, as shown in fig. 3, the first conductive end 333 is separated from the second conductive end 311, the controller 212 senses that the closing signals of the first conductive end 333 and the second conductive end 311 are interrupted, the controller 212 controls the electronic switch 4 to be switched off, so that the power supply circuit for supplying power to the atomizer 1 by the battery assembly 2 is switched off, and the battery assembly 2 stops supplying voltage to the atomizer 1.

Referring to fig. 8, in another embodiment, the airflow switch component 3 is in a circuit relationship, and the airflow switch component 3 may be disposed on a power supply circuit for supplying power to the atomizer 1 through the battery component 2, specifically, one end of the battery 22 is electrically connected to the heating element 161, the other end of the battery 22 is electrically connected to the first conductive terminal 333, and the heating element 161 is further electrically connected to the second conductive terminal 311. Thus, when the first conductive terminal 333 contacts the second conductive terminal 311, the power supply line between the battery assembly 2 and the atomizer 1 is turned on, and the battery assembly 2 can provide the operating voltage to the atomizer 1.

The specific application scenario may be: when a user smokes, first, an air flow enters into the air flow path through the air inlet 12. Then, the blade 332 rotates the rotating shaft 331 under the action of the airflow, as shown in fig. 4, so that the first conductive terminal 333 contacts with the second conductive terminal 311. And then the power supply line between the battery pack 2 and the atomizer 1 is conducted, and the battery pack 2 can supply voltage to the atomizer 1. When the user stops smoking, the blade 332 returns to the natural state under the elastic action of the elastic member 32, as shown in fig. 3, the first conductive terminal 333 is separated from the second conductive terminal 311, and the power supply line between the battery assembly 2 and the atomizer 1 is cut off, so that the battery assembly 2 stops supplying voltage to the atomizer 1.

It should be noted that the above-mentioned natural state is that the elastic member 32 is not deformed, and the first conductive terminal 333 is separated from the second conductive terminal 311.

The contact and separation of the first conductive terminal 333 and the second conductive terminal 311 should satisfy the following conditions:

the elasticity of the elastic member 32 needs to be within a predetermined range. If the elastic member 32 is easily deformed, the first conductive terminal 333 is easily contacted with the second conductive terminal 311, for example, if the air inlet 12 slightly feeds air, the first conductive terminal 333 is contacted with the second conductive terminal 311, and obviously, the electronic cigarette is unsafe in this case. In this case, if the elastic member 32 is hardly deformed, it is not reasonable that the user needs to use a large force to make the first conductive terminal 333 contact with the second conductive terminal 311 when smoking. Thus, the elasticity of the elastic member 32 should be moderate, with a specific moderate range depending on trial and error testing.

Based on the above structure, when a user uses the electronic cigarette to smoke, air enters the electronic cigarette through the air inlet 12, an air flow flows in the air flow path, and the blade 332 is pushed to rotate when the air flow passes through the blade 332. The blade 332 drives the rotating shaft 331 to rotate, so that the first conductive terminal 333 on the rotating shaft 331 contacts the second conductive terminal 311 on the fixing plate 31. Thus, the battery assembly 2 supplies the operating voltage to the atomizer 1. When the user stops smoking, no airflow flows in the airflow path, the blade 332 is reset to the natural state under the elastic force of the elastic member 32, the first conductive terminal 333 is separated from the second conductive terminal 311, and thus, the battery assembly 2 stops supplying the operating voltage to the atomizer 1.

Alternatively, the elastic member 32 may be a torsion spring, and two ends of the torsion spring respectively extend out of one end, one end of the torsion spring is fixed to the blade 332, and the other end of the torsion spring is fixed to the fixing plate 31.

In an embodiment of the present disclosure, the electronic cigarette includes an atomizer, a battery module, and an airflow switch module, where the airflow switch module is controlled by airflow to perform a switching function thereof and is disposed on an airflow path of the electronic cigarette. Therefore, when a user uses the electronic cigarette to smoke, the airflow switch assembly controls the battery assembly to supply power to the atomizer under the action of airflow; when the user stops smoking, no airflow passes through the airflow passage, and the battery pack stops supplying power to the atomizer. Therefore, when the user uses the electronic cigarette, the user does not need to smoke through frequently pressing the mechanical switch, the damage of the mechanical switch is avoided, and the service life of the electronic cigarette can be prolonged.
