Please refer to FIGS. 1 to 3 , the electronic cigarette includes an electronic cigarette main body 1 , an induction assembly 2 and a button assembly 3 electrically connected to the electronic cigarette main body 1 respectively, and the button assembly 3 is installed on the electronic cigarette Inside the main body 1 , the electronic cigarette main body 1 is provided with a first installation hole 12 , the induction component 2 is installed in the first installation hole 12 , and one side of the electronic cigarette main body 1 is exposed from the first installation hole 12 The other side is at least partially facing the button assembly 3 to form a touch sensing area for the user to touch. When the touch sensing area is pressed, the sensing assembly 2 moves relative to the electronic cigarette body 1 and aligns with the electronic cigarette body 1 . The button assembly 3 applies pressure to trigger the button assembly 3 . In this embodiment, by configuring the sensing component 2 and the button component 3 on the main body 1 of the electronic cigarette, when the sensing component 2 is touched, the button component 3 is pressed to trigger the corresponding function. In this way, the probability of false triggering of the buttons of the electronic cigarette can be greatly reduced, and the function of the electronic cigarette can be prevented from being aerated when the user does not need it, thereby improving the safety of using the electronic cigarette and saving energy consumption at the same time.

In this embodiment, as shown in FIG. 2 and FIG. 4 , the electronic cigarette main body 1 includes a casing 11 , and the casing 11 accommodates components such as battery elements, power supply lines, and main control boards. 11 is provided with a first mounting hole 12 for mounting the induction assembly 2 . The induction assembly 2 includes an induction board 22 , a first circuit board 23 and a mounting seat 21 . The mounting seat 21 includes a body 211 and a limiting ring 212 . The body 211 is provided with a second installation hole 213 , and the induction plate 22 is installed in the second installation hole 213 and exposed from the second installation hole 213 . Since the main body 211 is installed in the first installation hole 12 from the inside of the casing 11 , the shape of the main body 211 matches the shape of the first installation hole 12 . When the body 211 is installed in the first installation hole 12 , the second installation hole 213 at least partially overlaps with the first installation hole 12 , so that the induction board 22 overlaps from the two installation holes. A part is exposed outside the casing 11 to form a touch-sensitive area for the user to touch. Preferably, the second installation hole 213 and the first installation hole 12 are coaxially arranged, so that the area of the touch sensing area can be maximized, thereby increasing the area that the user can touch, which is convenient for the user to operate .

Further, as shown in FIG. 3 , the body 211 is in clearance fit with the first mounting hole 12 , so that the body 211 can move relative to the housing 11 along the extending direction of the first mounting hole 12 . At least two opposite side ends of the induction plate 22 are in interference fit with the second installation holes 213 . In this way, when the induction plate 22 is under pressure, the induction plate 22 can drive the mounting seat 21 to move into the casing 11 relative to the casing 11 to trigger the button assembly 3 . Preferably, each side end of the induction plate 22 is in an interference fit with the second installation hole 213 , which can not only increase the force between the induction plate 22 and the wall of the second installation hole 213 , to prevent the relative displacement of the induction plate 22 and the hole wall of the second installation hole 213 , and to balance the force on each side of the induction plate 22 to prevent the induction plate 22 from being damaged due to uneven force during the pressing process. It is worth noting that, in practical applications, the effect of mutual contact between the two can be improved by increasing the roughness of the hole wall of the second mounting hole 213 and/or the side wall of the induction plate 22 force.

In this embodiment, since the body 211 and the first installation hole 12 are in clearance fit, the limit ring 212 is used to limit the movement of the body 211 to prevent the body 211 from moving from any position during the movement. The first mounting hole 12 comes out of the housing 11 . Specifically, the limiting ring 212 is protruded from the outer circumference of the main body 211 in the circumferential direction. When the body 211 is installed in the first installation hole 12 , the surface of the limiting ring 212 is parallel to the first end surface of the first installation hole 12 in the housing 11 . There may be a gap between the two, or they may be attached together. When the main body 211 moves into the housing 11 along the extending direction of the first installation hole 12 under the driving of the induction plate 22 , the main body 211 drives the limiting ring 212 to move, so that the limiting ring 212 and the The gap between the first end faces gradually increases; when the pressure on the sensing plate 22 is removed, the sensing assembly 2 moves back under the action of the button assembly 3, and the space between the limiting ring 212 and the first end face is The gap gradually decreases until the limiting ring 212 abuts on the first end face and stops moving, thereby realizing the limiting position of the main body 211 when it moves back and preventing the main body 211 from coming out of the first mounting hole 12 .

Further, as shown in FIG. 2 and FIG. 3 , in order to prevent the induction plate 22 from being displaced relative to the hole wall of the second mounting hole 213 when it is pressed or moved by a restoring force, or even coming out of the second mounting hole 213 . The side of the induction plate 22 exposed from the second installation hole 213 outside the casing 11 is provided with a first step 221 along the circumferential direction. Correspondingly, the hole wall of the second installation hole 213 is provided with a first step 221 is adapted to the second step 2111. Wherein, the second step 2111 is placed on the first step 221, so that when the induction plate 22 returns to the position before pressing under the action of the restoring force, the exposed end face of the induction plate 22 is affected by the The limiting force of the second step 2111 is described. In this way, on the one hand, the second step 2111 can be covered on the first step 221 in the axial direction, so that the gap between the induction plate 22 and the second installation hole 213 is covered, which protects the Induction board 22 and the role of aesthetics. On the other hand, the force between the mounting seat 21 and the induction plate 22 is increased.

Further, the surface of the second step 2111 exposed on the second mounting hole 213 is an arc-shaped transition surface, the arc-shaped transition surface is an annular surface, and the large diameter end thereof is connected to the surface of the electronic cigarette body 1 , namely The second end surface of the first mounting hole 12 located outside the casing 11 is connected to each other. The small diameter end is in contact with the exposed surface of the induction plate 22 . The large diameter end of the arc-shaped transition surface smoothly transitions with the first end surface, and the small diameter end smoothly transitions with the surface of the induction plate 22 . In this way, not only the aesthetics of the outer surface of the electronic cigarette is ensured, but also the user is prevented from touching and pressing the sensor board 22 to have a smooth hand feeling and scratching the hand.

In this embodiment, the first side of the first circuit board 23 on which the sensing circuit is printed is attached to the sensing board 22 , and the second side opposite to the first side is located on the button assembly 3 . The position of the first circuit board 23 is restricted from both sides by the induction board 22 and the button assembly 3 . The induction circuit is electrically connected with the main control board of the electronic cigarette. Since the human body is a conductor, when the user's skin touches the sensor pad 22, the sensor pad 22 generates a touch signal by inducing a weak current of the human body, and conducts the touch signal to the sensing circuit, and then the sensing circuit generates a touch signal. Corresponding electrical signals are transmitted to the main control board. In practical applications, the induction plate 22 can be a metal plate or a plate made of plastic. Wherein, when the induction plate 22 is made of metal, the mounting seat 21 in contact with the induction plate 22 must be made of a non-conductive material, such as plastic, so as to prevent the current on the induction plate 22 from being directly introduced into the mounting seat 21 and unable to be transmitted to the Induction circuit, resulting in the problem of induction failure. When the induction plate 22 is made of plastic material, the thickness of the induction plate 22 is less than or equal to 3 mm, so as to prevent the induction plate 22 from being too thick so that static electricity cannot be conducted to the induction circuit.

In this embodiment, as shown in FIG. 2 and FIG. 3 , the button assembly 3 includes a mounting plate 32 and a switch 31 , and the switch 31 is welded to the second circuit board 23 away from the sensing board 22 . side. Wherein, a button control circuit is printed on the second side, and the button control circuit is electrically connected with the main control board of the electronic cigarette. By printing the button control circuit on the second side of the first circuit board 23, not only the space on the surface of the first circuit board 23 is fully utilized, but also the space occupied by the induction component 2 and the button component 3 is reduced, which is beneficial to the electronic cigarette Thin and light direction development.

It should be noted that, in a variant embodiment of the present invention, the key assembly 3 may include a mounting plate 32 and a second circuit board. The second circuit board is attached to the side of the first circuit board 23 away from the sensing board 22 , and the second circuit board is away from the first circuit board 23 , that is, the side facing the mounting board 32 . A key control circuit is printed on one side. Correspondingly, the switch 31 is welded to the side of the second circuit board, and is electrically connected to the key control circuit.

The mounting plate 32 is fastened to the electronic cigarette body 1 and located on the side of the switch 31 away from the first circuit board 23 . A pressing portion 321 protrudes from the mounting plate 32 facing the switch 31 , and a second gap exists between the pressing portion 321 and the switch 31 to form a pressing stroke of the sensing assembly 2 . When the sensing board 22 is pressed, the sensing board 22 drives the mounting seat 21 , the first circuit board 23 and the switch 31 to move toward the mounting board 32 until the moving stroke reaches the pressing portion 321 and the switch 31 . 31 , the switch 31 is in contact with the pressing portion 321 and exerts a pressure on the pressing portion 321 , and in turn the mounting plate 32 exerts a reaction force on the switch 31 to trigger the switch 31 . In practical applications, the pressing portion 321 is located at the center of the mounting plate 32, and the mounting plate 32 is symmetrically provided with at least a pair of connecting holes 322 with the switch 31/pressing portion 321 as the center. The connecting pieces respectively pass through the at least one pair of connecting holes 322 to fasten the mounting plate 32 to the electronic cigarette main body 1 . This ensures that the mounting plate 32 receives a uniform force, so that when the pressing portion 321 is pressed by the switch 31 , the mounting plate 32 will not vibrate to affect the smooth triggering of the switch 31 .

Further, as shown in FIG. 2 and FIG. 3 , the electronic cigarette further includes a silica gel seat 4 , and the silica gel seat 4 is located between the sensing component 2 and the mounting plate 32 , and is connected with the mounting plate 32 and the sensing component 2 . form a support space. Both the switch 31 and the pressing portion 321 are accommodated in the support space. The silicone seat 4 is arranged between the induction assembly 2 and the mounting plate 32 to buffer the pressure formed by the induction assembly 2 and at the same time to support the second circuit board. In order to ensure the smooth triggering of the switch 31, a first gap exists between the silicone base 4 and the sensing component 2, and the width of the first gap is greater than the width of the second gap. In this way, enough space is reserved to ensure that the switch 31 can be pressed against the pressing portion 321 .

The present invention also provides a control method for an electronic cigarette, which is applied to any of the electronic cigarettes described above. As shown in FIG. 5 , the control method includes:

S10. When the sensing component 2 of the electronic cigarette is touched, the sensing component 2 determines whether the touch is a biological touch;

S20. In the case of biological touch, the button assembly 3 monitors the button operation within a preset time, and triggers a corresponding instruction when monitored.

In this embodiment, by first determining whether the electronic cigarette is in contact with biological touch, and further determining whether the electronic cigarette has received a key operation, the corresponding instruction is triggered, which effectively reduces the record of false triggering of the electronic cigarette key, and improves the electronic cigarette. safety of use.

Specifically, in the step S10, the induction plate 22 can work only when it passes through any object holding electric charge. The electric charge is stored in the micro-electrostatic net. Since the human body is a weak conductor, when a finger touches the sensing plate 22, a small amount of current will be absorbed from the sensing area, resulting in a voltage drop of the corner electrodes, so as to utilize the method of sensing the weak current of the human body. To achieve the purpose of identifying whether it is biological touch. This method can prevent non-biological touches from triggering corresponding commands. For example, when clothing rubs the sensor pad 22 or the user touches the sensor pad 22 with gloves on, the sensor pad 22 will not be recognized as a biological touch and then send a signal to the sensing circuit. In this way, the user will not trigger the operation of the electronic cigarette due to the contact between the induction plate 22 and non-living organisms during use, which greatly reduces the probability of the electronic cigarette being triggered by mistake.

In the step S20, in order to further reduce the probability of the electronic cigarette being triggered by mistake, it is also determined whether the received biological touch is sent by a specific user, so as to prevent users without authority from using the electronic cigarette and ensure the safety of the electronic cigarette. sex.

Exemplarily, when it is biological touch, the button assembly 3 monitors the button operation within a preset time, and when monitored, triggering the corresponding instruction specifically includes:

S21. When it is a biological touch, the sensing component 2 acquires a biological identifier corresponding to the biological touch;

S22, searching for the acquired biological identifier in a preset biological identifier library;

S23. When the biological identifier is found, the button assembly 3 monitors the button operation within a preset time, and triggers a corresponding instruction when monitored.

Specifically, in the step S21 and the step S22, the biological identifier is the unique identifier of each biological touch. such as fingerprint information. In this embodiment, a biological identification library is generated in advance in the electronic cigarette, wherein at least one preset biological identification is stored in the biological identification library. The biological identifier library can be imported from the system, or generated by the user entering biological identifiers according to actual needs. It can be understood that the user can set, add or delete preset biomarkers in the biomarker library according to requirements. When the sensing component 2 receives a biological touch, it acquires a biological identifier corresponding to the biological touch, and searches for the acquired biological identifier in a preset biological identifier library. When a preset biological identifier whose similarity is greater than a preset value is stored in the biological identifier library, it is determined that the search is successful, and step S23 is executed at this time. When there is no preset biometric identifier whose similarity with the biometric identifier is greater than the preset value in the biometric identifier library, it is determined that the search fails, indicating that the biological touch received by the sensing component 2 is from a user who does not have permission. At this time, the electronic Smoke continues to listen for the next touch operation.

In the step S23, the preset time refers to a short period of time, such as 0.1S, 1S, and the like. After the biometric identifier is successfully matched, the button assembly 3 monitors the button operation within a preset time, and when the button operation is monitored, a corresponding instruction is triggered to control the electronic cigarette to perform the corresponding operation. When the key operation is not monitored within the preset time, the electronic cigarette continues to monitor the touch operation. In this embodiment, on the basis of recognizing the biological touch, it is further determined whether the biological touch has the authority to use the electronic cigarette, and at the same time, it is necessary to monitor the key operation within a preset time before triggering the corresponding command, which greatly reduces the electronic cigarette. The probability of being triggered by mistake, thereby improving the safety of electronic cigarette use, and helping to save energy consumption of electronic cigarettes.
