This application claims priority to Chinese Patent Application No. 202310992670.5, filed on Aug. 8, 2023, the disclosure of which is incorporated herein by reference in its entirety.
The present disclosure relates to electronic product production technologies, and more particularly, to an aerosol generating apparatus.
With the daily use of electronic products, there is an increasing demand for aerosol generating apparatuses. Generally, the activation mode of the aerosol generating apparatus mainly uses mechanical button control or breath detector control. When the activation of aerosol generating apparatus is controlled by a mechanical button, the activation is implemented by pressing or sliding the mechanical button. But the mechanical button is likely to be damaged or malfunctioned after long-time use, thereby affecting the activation of the aerosol generating apparatus. When a breath detector is used to control the activation of the aerosol generating apparatus, the breath detector, as a signal collector, senses the flow of air to control the aerosol generating apparatus to start operation or stop operation. However, oil or other liquid is likely to enter the breath detector to cause automatic activation and lighting of the atomizer, thereby causing failure or malfunction of the aerosol generating apparatus. In a serious case, property loss and the like is caused due to a fire and other related accidents. Based on the situation, the activation structure of a general aerosol generating apparatus is unstable, and is prone to automatic activation or activation failure.
According to one or more embodiments of the present disclosure, an aerosol generating apparatus includes: a case comprising a suction nozzle; an atomization component disposed in the case; and a sensing component disposed at the suction nozzle, connected to the atomization component, and being for generating a sensing signal in response to sensing that a user is in contact with the suction nozzle and transmitting the sensing signal to the atomization component.
Some embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. The embodiments are described for illustrative purposes only and are not intended to limit the present disclosure.
Referring to
Specifically, the aerosol generating apparatus includes a case 100, and the inner parts of the aerosol generating apparatus are all located inside the case 100. The top portion of the case 100 forms the suction nozzle 110 to facilitate suction by a user. The suction nozzle 110 has multiple shapes, which may be flat, round, or the like. The aerosol generating apparatus further includes an atomization component 200 configured to atomize an aerosol generating matrix to form aerosol. The atomization component 200 includes an atomization device, a control device, an atomization base, and the like. The control device includes an integrated circuit and a processor or microcontroller such as (Micro Control Unit) MCU. The integrated circuit can collect, calculate, and process a sensing signal, and send the processed sensing signal to the processor or microcontroller such as MCU to control whether the aerosol generating apparatus operates or not. Also, the aerosol generating apparatus further includes a sensing component 300 which is connected to the atomization component 200 and is configured to sense whether the user's lips are in contact with the suction nozzle 110, generate a sensing signal if the user's lips are in contact with the suction nozzle 110, and transmit the sensing signal to the atomization component 200, thereby achieving lighting control of the aerosol generating apparatus.
In one or more embodiments of the present disclosure, the aerosol generating apparatus is a circular lip sensor and atomizer. When the user's lips are close to the suction nozzle 110, the sensing component 300 senses a strain pressure generated when the user's lips are in contact with the suction nozzle 110, to generate a sensing signal. Then the sensing component 300 transmits the sensing signal to the atomization component 200, so that the atomization component 200 is powered on to perform atomization, thereby activating the aerosol generating apparatus. When the user's lips leave the suction nozzle 110, the sensing component 300 senses no pressure, so that no sensing signal is generated, and the atomization component 200 stops operation.
According to one or more embodiments of the present disclosure, by providing the sensing component 300 connected to the atomization component 200 at the suction nozzle 110, when the sensing component 300 senses that a user's lips are in contact with the aerosol generating apparatus, a sensing signal is generated and is transmitted to the atomization component 200. Thus, the atomization component 200 is activated to atomize an aerosol generating matrix to enable a user to suction the aerosol, in order to control whether the aerosol generating apparatus is activated by sensing whether the user's lips are in contact with the aerosol generating apparatus. The structure is simple and triggers the activation of the aerosol generating apparatus by sensing the user's lip, thereby preventing automatic activation or activation failure of the aerosol generating apparatus, and improving the stability of the activation of the aerosol generating apparatus. Moreover, the activation operation is simple to enable the user's direct suction, which is more convenient for the user's suction and improves the user's experience.

In particular, in one or more embodiments of the present disclosure, the sensing component 300 has multiple sensing members 310 which are disposed along the circumferential direction of the suction nozzle 110. When one of the sensing members 310 is damaged, another one of the sensing members 310 can still work, so that the aerosol generating apparatus can still work to increase the service life of the aerosol generating apparatus and reduce waste.

In one or more embodiments of the present disclosure, as shown in
In one or more embodiments of the present disclosure, the aerosol generating apparatus further includes a protection cover, which is sleeved outside the suction nozzle 110 and slidably connected to the suction nozzle 110. The protection cover may cover the mounting groove 131. Specifically, the protection cover is sleeved outside the suction nozzle 110 of the outer case 130. The size of the protection cover is smaller than that of the suction nozzle 110, and the protection cover can slide along the height direction of the suction nozzle 110. The protection cover can cover the mounting groove 131, thereby enabling protection of the sensing member 310 located in the mounting groove 131 and avoiding false activation. When the user needs to suction, the protection cover may be slid downwards to expose the sensing member 310 to the outside, so that the sensing member 310 may sense whether the user's lips are in contact with the suction nozzle 110 to generate a sensing signal, thereby enabling detection and sensing of lighting and enabling suction. When the user does not need to suction, the protection cover is slid upwards to make the protection cover to cover the mounting groove 131, so that the sensing member 310 does not come into contact with the outside, thereby preventing the user from being mistakenly in contact with the suction nozzle 110, which may cause the activation of the aerosol generating apparatus, and finally cause an accident or failure of the aerosol generating apparatus.
In one or more embodiments of the present disclosure, referring to
In particular, the isolation member 320 is fixed to the sensing member 310 in multiple ways. In one or more embodiments of the present disclosure, the isolation member 320 is fixed to the sensing member 310 by an adhesive connection method. A back adhesive is provided on the isolation member 320, that is, the back adhesive is provided on a side of the isolation member 320 facing the inner case 120, so that the sensing member 310 is adhered to the back adhesive, thereby realizing the fixing of the isolation member 320 and the sensing member 310. The material of the back adhesive is not limited, and only needs to have an adhesive function. The connection method is simple and has a low production cost.
In one or more embodiments of the present disclosure, the sensing member 310 is a strip strain gauge, and is protected by the isolation member 320. During the user's suction, the sensing member 310 is in direct contact with the isolation member 320. The isolation member 320 deforms under pressure, and the sensing member 310 senses the deformation of the isolation member 320 to generate a strain change, and converts the strain change into a resistance change. The sensing member 310 generates a sensing signal, and transmits the sensing signal to the atomization component 200 through a connection line 330, thereby implementing the activation of the aerosol generating apparatus. The structure is simple, the sensing member 310 is protected and suction of the user can also be sensed, thereby implementing the activation or stoppage of the aerosol generating apparatus and improving the stability of the activation of the aerosol generating apparatus.
In one or more embodiments of the present disclosure, the isolation member 320 is made of a silica gel material. Specifically, the isolation member 320 is provided on an outer side of the sensing member 310 to isolate the sensing member 310 from the outside. Therefore, during the user's suction, the user's lips are in contact with the aerosol generating apparatus, that is, the user's lips are in contact with the isolation member 320, so that the sensing member 310 senses contact between the user's lips and the suction nozzle 110. Therefore, the isolation member 320 is made of silica gel which has softness and good elasticity. When the user is in contact with the isolation member 320, the user will not feel hard to affect the experience. The isolation member 320 can be restored to an original state after the suction of the user, so that the sensing member 310 cannot sense the contact and the operation of the aerosol generating apparatus is stopped. Also, the isolation member 320 can also better transmit the pressure brought by the user, so that the sensing member 310 fully senses the contact of the lip, thereby making the sensing component 300 more sensitive and more efficient in operation. On the other hand, the silica gel material of the isolation member 320 has a good scaling property and can better isolate the sensing member 310 to prevent external dust, water droplets, and the like from entering the inner side of the outer case 130, so that the sensing component 300 is further protected. In particular, the isolation member 320 in one or more embodiments adopts a sensing silica gel isolation sheet, which is an annular band made of silica gel which has good elasticity and can be restored in shape.

In one or more embodiments of the present disclosure, the sensing member 310 adopts a strain pressure sensing probe, thus the first connection line 331 is a positive line of the strain pressure sensing probe, and the second connection line 332 is a negative line of the strain pressure sensing probe. The first connection line 331 serving as a supply electrode lead of the strain pressure sensing probe, the second connection line 332 serving as an electrode lead for outputting a differential signal, a resistive strain gauge made of a material having a temperature coefficient close to infinitesimal, and a fixed-value resistor having a very small temperature coefficient form Res Bridge by etching. The circuit senses whether a person's lips are in contact with an atomizer and uses a subsequent related circuit for signal acquisition, calculation, processing, transmission to a processor or microcontroller such as MCU, and the like. The structure is simple, and the connection line 330 is connected to the atomization component 200 through a probe connection point 414.
In one or more embodiments of the present disclosure, referring to
Specifically, according to one or more embodiments of the present disclosure, a method for assembling the aerosol generating apparatus includes: welding the sensing member 310 and the connection line 330 to form the sensing component 300, inserting the sensing component 300 into the outer case 130, sleeving the outer case 130 into which the sensing component 300 is inserted on the inner case 120, welding the connection line 330 which passes through an atomizer base 411, the atomizing core 415 and an atomization core base 413 to the probe connection point 414, and assembling the atomizing core 415. The atomizer base 411 is provided with a cover 412 covering a liquid injection hole.
In particular, according to one or more embodiments of the present disclosure, a sensing detection processing operation circuit for electronic atomizer control is further provided. The sensing module 300 includes a lip detection circuit, a lip signal first operation circuit, a lip signal second operation circuit, and a lip signal third operation circuit. The three parts sense, collect, and process that the user's lips are near the suction nozzle 110, transmit sense signal to the corresponding processing circuit to obtain a processed sense signal, and transmit the processed sense signal to the main control board (Printed Circuit Board Assembly, PCBA) of the MCU of the atomization component 200 to control the atomization component 200 to start lighting. When the user's lips leave and is sensed to leave, lighting is stopped.
The aerosol generating apparatus according to one or more embodiments of the present disclosure is different from a related aerosol generating apparatus whose lighting technique focuses on a mechanical button and detection of air path and air flow. An aerosol generating apparatus that senses the contact between the user's lips and the suction nozzle 110 to trigger lighting is provided, thereby preventing automatic activation or activation failure of the aerosol generation device, and improving the stability of the activation of the aerosol generating apparatus.
