DETAILED DESCRIPTION

[0028] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. Now, the preferred embodiments of the present application will be described in detail with reference to the drawings.

[0029] Referring to FIGS. 1 to Figure 7 It is shown that an embodiment of the aerosol generating device of the present application. The aerosol generating device includes a shell 412, an atomization assembly 100 and an induction assembly 200, the shell 412 includes a flat-shaped suction nozzle 419; the atomization assembly 100 is arranged inside the shell 412; the induction assembly 200 is arranged on the flat-shaped suction nozzle 419, and the induction assembly 200 is connected with the atomization assembly 100, the induction assembly 200 is used for sensing the contact of the user with the flat-shaped suction nozzle 419 to generate a sensing signal and transmitting the sensing signal to the atomization assembly 100.

[0030] Specifically, the flat-shaped suction nozzle 419 of the aerosol generating device of the present embodiment is flat-shaped; the induction assembly 200 is used for sensing whether the user contacts the aerosol generating device, and if so, generating a sensing signal and transmitting the sensing signal to the atomization assembly 100; the atomization assembly 100 is used for atomizing the aerosol generating substrate to form an aerosol, the atomization assembly 100 includes an atomization device, a control device, an atomization base, etc., the control device is composed of a processor and a microcontroller such as an integrated circuit and an MCU, the integrated circuit can collect, operate and process the sensing signal, and send the processed sensing signal to the processor and the microcontroller such as the MCU, so as to control whether the aerosol generating device works.

[0031] The application sets the induction assembly 200 on the flat-shaped suction nozzle 419, and connects the induction assembly 200 with the atomization assembly 100. When the induction assembly 200 senses that the user's lips contact the aerosol generating device, a sensing signal is generated and transmitted to the atomization assembly 100, so that the atomization assembly 100 starts to atomize the aerosol generating substrate, so that the user inhales the aerosol, thereby achieving the control of the aerosol generating device by sensing whether the user's lips contact the aerosol generating device to control whether the aerosol generating device starts. The structure is simple, and the start function of the aerosol generating device is triggered by sensing the user's lips, preventing the aerosol generating device from starting automatically or failing to start, improving the start stability of the aerosol generating device; and the start operation is simple, the user can directly inhale, which is more convenient for the user to inhale, improving the user's experience.

[0032] In an embodiment, referring to FIGS. 1-3, the flat-shaped suction nozzle 419 includes first and second flat surfaces 4191 and 4192 arranged opposite to each other, and the induction assembly 200 includes two induction pieces 210, i.e., first and second induction pieces 211 and 212. The first induction piece 211 is arranged on the first flat surface 4191, and the second induction piece 212 is arranged on the second flat surface 4192.

[0033] Specifically, since the flat-shaped suction nozzle 419 of the aerosol generating device is flat-shaped, the flat-shaped suction nozzle 419 forms two flat surfaces arranged opposite to each other, i.e., the first and second flat surfaces 4191 and 4192, thereby facilitating the user's inhalation. Meanwhile, the induction assembly 200 further includes induction pieces 210 for sensing whether the user contacts the aerosol generating device to generate a sensing signal. The induction pieces 210 are arranged on the first and second flat surfaces 4191 and 4192. The induction piece 210 arranged on the first flat surface 4191 is the first induction piece 211, and the induction piece 210 arranged on the second flat surface 4192 is the second induction piece 212. Thus, the first and second flat surfaces 4191 and 4192 can both sense whether the user's lips contact the flat-shaped suction nozzle 419 to generate a sensing signal, thereby making the induction of the aerosol generating device more sensitive. When the user inhales, the user's two lip petals directly contact the first and second flat surfaces 4191 and 4192. Therefore, arranging the first and second induction pieces 211 and 212 on the first and second flat surfaces 4191 and 4192 respectively can ensure the contact between the user and the induction pieces, thereby ensuring the normal operation of the aerosol generating device.

[0034] In the embodiment, the inductor 210 adopts a strain pressure sensing probe. When the user's lips are close to the inductor 210, the inductor 210 senses the strain pressure generated when the user's lips contact the flat suction nozzle 419, so that the inductor 210 generates a sensing signal, which is transmitted to the atomization assembly 100 through the connecting wire 220, so that the atomization assembly 100 is powered on to perform atomization work, thereby starting the aerosol generating device. When the user's lips are away from the flat suction nozzle 419, the inductor 210 does not sense the pressure, so that no sensing signal is generated, and the atomization assembly 100 stops working.

[0035] In an embodiment, referring to FIGS. 1 to Figure 4 As shown in the drawings, the first inductor 211 and the second inductor 212 are both strip-shaped bodies. The two ends of the first inductor 211 extend to the two side edges of the first flat surface 4191, respectively, and the two ends of the second inductor 212 extend to the two side edges of the second flat surface 4192, respectively. Specifically, the first inductor 211 and the second inductor 212 are arranged as strip-shaped bodies. The shapes of the first inductor 211 and the second inductor 212 are close to the shape of the user's lips, so that the first inductor 211 and the second inductor 212 can quickly sense whether the user's lips contact the flat suction nozzle 419. In addition, the first inductor 211 and the second inductor 212 can be more conveniently installed on the flat suction nozzle 419. The first inductor 211 and the second inductor 212 are arranged as a sheet structure, which can make the first inductor 211 and the second inductor 212 more closely fit the shape of the flat suction nozzle 419, so that the sensitivity of the inductor 210 is higher. Meanwhile, the two ends of the first inductor 211 extend to the two side edges of the first flat surface 4191, and the two ends of the second inductor 212 extend to the two side edges of the second flat surface 4192. The first inductor 211 covers one end of the first flat surface 4191, and the second inductor 212 covers one end of the second flat surface 4192. That is, the range of the first inductor 211 and the second inductor 212 is larger, which increases the sensing range of the first inductor 211 and the second inductor 212, and improves the sensitivity and working efficiency of the first inductor 211 and the second inductor 212.

[0036] In a specific embodiment, referring to Figure 4As shown, the first induction piece 211 and the second induction piece 212 are both flexible sheets, and the flexible sheets are etched with reciprocating curved lines along the length direction thereof. Specifically, the first induction piece 211 and the second induction piece 212 are arranged as flexible sheets, so that the elasticity of the first induction piece 211 and the second induction piece 212 is better, and the first induction piece 211 and the second induction piece 212 can be bent to be fixed on the flat-shaped mouthpiece 419 according to different parameters of the flat-shaped mouthpiece 419 of the aerosol generating device, so that the first induction piece 211 and the second induction piece 212 are arranged more closely to the flat-shaped mouthpiece 419, facilitating installation and fixation. The flexible sheet can be etched into any pattern, which is not limited herein. In this embodiment, the flexible sheet is further etched with reciprocating curved lines along the length direction thereof, so that the flexible sheet can form a certain loop to realize normal work of the flexible sheet, and the structure is stable, reducing the short circuit of the flexible sheet.

[0037] In specific embodiments, reference is made to Figure 4 As shown, the induction piece 210 is composed of a resistance strain gauge and a fixed value resistor. Specifically, the resistance strain gauge is an element for measuring strain, which can convert the change of strain on a mechanical member into resistance change; the fixed value resistor is a common resistor, which is characterized in that the resistance value thereof will not change measurably due to natural or artificial factors under normal circumstances, and the fixed value resistor is often used in electronic equipment to stabilize the voltage or current of the circuit. The induction piece 210 has an induction function, so a strain pressure sensor probe is adopted in this embodiment, the induction piece 210 is made of a resistance strain gauge with a temperature coefficient close to infinitesimal and a fixed value resistor with a very small temperature coefficient, and the induction piece 210 can be etched into any pattern. This structure is simple, the generation cost is low, and the strain of the external structure can be converted into resistance change, so as to generate a sensing signal, which is sensitive and can improve work efficiency.

[0038] In a specific embodiment, referring to FIG. 1, the sensing assembly 200 further comprises two isolation pieces 230, which are respectively fixedly connected with the first sensing piece 211 and the second sensing piece 212, and the isolation pieces 230 isolate the first sensing piece 211 or the second sensing piece 212 from the outside. Specifically, since the sensing piece 210 is a sensing sensitive device, it is easy to be damaged, and therefore the isolation pieces 230 are arranged at the part of the sensing piece 210 in contact with the outside. In this embodiment, the sensing piece 210 is arranged outside the shell 412 of the aerosol generating device, which can form an oil storage compartment or fix some internal parts of the aerosol generating device, such as an air channel pipe, an atomizing core 417, an oil storage compartment, etc., in the shell 412. Arranging the sensing piece 210 outside the shell 412 facilitates the sensing piece 210 to sense whether the user is in contact with the aerosol generating device. The isolation pieces 230 are similar in shape to the sensing piece 210, one side surface of the sensing piece 210 is fixedly connected with one side surface of the isolation piece 230, the isolation piece 230 wraps the one side surface of the sensing piece 210, thereby isolating the sensing piece 210 from the outside and avoiding the sensing piece 210 from being damaged by the outside, and protecting the sensing piece 210.

[0039] Specifically, the isolation pieces 230 can be in a sheet structure or a three-dimensional structure, which are not limited herein, and the isolation pieces 230 only have the function of isolating the part of the sensing piece 210 in contact with the outside. The two isolation pieces 230 of this embodiment are respectively fixedly connected with the first sensing piece 211 and the second sensing piece 212, thereby ensuring the normal work of the first sensing piece 211 and the second sensing piece 212.

[0040] In this embodiment, the sensing piece 210 is a strip-shaped strain gauge, which is isolated and protected by the isolation pieces 230. When the user inhales, the isolation pieces 230 are directly in contact with the user, and the isolation pieces 230 are deformed under the pressure, the sensing piece 210 senses the deformation of the isolation pieces 230 and generates a strain change, the strain change is converted into a resistance change, the sensing piece 210 generates a sensing signal, and the sensing signal is transmitted to the atomizing assembly 100 by the connecting wire 220, thereby realizing the start of the aerosol generating device. This structure is simple, and can protect the sensing piece 210 and sense the user's inhalation at the same time, thereby realizing the start or stop of the aerosol generating device and improving the start stability of the aerosol generating device.

[0041] In an embodiment, the isolating piece 230 is made of silica gel. Specifically, since the inductive piece 210 senses whether the user contacts the aerosol generating device through strain, and the inductive piece 210 is isolated from the outside by the isolating piece 230, when the user sucks, the user's lips contact the aerosol generating device, i.e. the user's lips contact the isolating piece 230, so that the inductive piece 210 senses the strain of the isolating piece 230. Therefore, the isolating piece 230 is made of silica gel, which has softness and good elasticity. When the user contacts the isolating piece 230, the user will not feel hard, thereby affecting the experience. After the user finishes sucking, the isolating piece 230 can return to its original state, so that the inductive piece 210 cannot sense the strain, and the work of the aerosol generating device is stopped. At the same time, the isolating piece 230 can also better transmit the pressure brought by the user, so that the inductive piece 210 fully senses the contact of the lips, thereby making the inductive assembly 200 more sensitive and more efficient. On the other hand, the silica gel material of the isolating piece 230 has good sealing performance, and can better isolate the inductive piece 210, prevent dust, water droplets and the like from the outside from entering the inside of the cover piece 300, and further protect the inductive piece 210. Specifically, the isolating piece 230 in the embodiment is an isolating piece of a sensing device made of silica gel with good elasticity and a recoverable shape, which forms a ring-shaped belt.

[0042] In specific embodiments, as shown in Figs. Figure 5 and Figure 6 the isolating piece 230 is adhesively connected to the first inductive piece 211 or the second inductive piece 212. Specifically, the isolating piece 230 and the first inductive piece 211 or the second inductive piece 212 can be fixed in various ways. In the embodiment, the isolating piece 230 and the first inductive piece 211 or the second inductive piece 212 are fixed by adhesive connection. Specifically, the isolating piece 230 is provided with a back adhesive 411 on the side facing the inside of the cover piece 300, so that the first inductive piece 211 or the second inductive piece 212 is adhered to the back adhesive 411, thereby achieving the fixation of the two. The material of the back adhesive 411 is not limited, as long as it has the function of adhesion. This connection method is simple and has low production cost.

[0043] In one embodiment, referring to Figures 1 and 2, the aerosol generating device further includes a cover 300, which is sleeved on the outside of the sensing component 200, and the isolation member 230 is fixedly connected to the cover 300. Specifically, the cover 300 serves as a carrier for the sensing component, bearing and supporting the sensing element 210, etc. Therefore, the cover 300 is sleeved on the outside of the sensing component 200. Since one side of the isolation member 230 is fixedly connected to the sensing element 210, the other side of the isolation member 230 is fixedly connected to the cover 300, so that the sensing element 210 is located inside the cover 300 and protected from it. Specifically, in this embodiment, the cover 300 is a transparent cover, which is similar to the housing 412 of the aerosol generator. The transparent cover is placed on the outside of the housing 412 of the aerosol generator, thereby surrounding the sensing component 200 between the cover 300 and the housing 412 of the aerosol generator. This prevents the sensing component 200 from being affected by external factors and the interior of the aerosol generator, thus enabling the sensing component 200 to work more stably.

[0044] In a specific embodiment, refer to Figures 2a to 2b As shown, the cover 300 includes a notch that is adapted to the isolation member 230, with the isolation member 230 embedded in the notch. Specifically, the cover 300 has a notch that is adapted to the shape and size of the isolation member 230, and the notch extends through both the inner and outer sides of the cover 300, allowing the isolation member 230 to be embedded in the notch and thus fixed to the cover 300, forming a sealed structure. The interior of the cover 300 forms a sealed space. The sensing element 210 is fixedly connected to the side of the isolation member 230 facing the interior of the cover 300. Therefore, the sensing element 210 is located within the sealed space of the cover 300, and the connecting line 220 is also located within the sealed space of the cover 300, preventing the sensing component 200 from contacting the outside world and ensuring its normal operation. This structure ensures the integrity and operational stability of the aerosol generator.

[0045] In one embodiment, reference is made to Figures 2a to 2bAs shown, the cover member 300 is provided with two notches, and the two notches are arranged on the opposite sides of the cover member 300, and the two notches are respectively provided with the isolating member 230 and the sensing member 210. Specifically, the flat-shaped mouthpiece 419 of the aerosol generating device is adapted to the user's mouth, and the flat-shaped mouthpiece 419 is generally provided in a cylindrical or flat structure. In the present embodiment, the aerosol generating device is a flat-shaped mouthpiece sensing sensor atomization cartridge, and therefore the cover member 300 has two wide surfaces, and when the user inhales, the two surfaces are respectively in contact with the user's upper lip and lower lip, and therefore two notches are respectively arranged on the two surfaces, and each notch is embedded with the isolating member 230 and the sensing member 210. Therefore, when the user inhales, it is not necessary to identify which surface has the isolating member 230 and the sensing member 210, and the user can directly inhale at the flat-shaped mouthpiece 419 of the aerosol generating device, which is more convenient for the user to operate. In addition, the cover member 300 is provided with two notches, and has two sensing assemblies 200, so that when one of the sensing assemblies 200 is damaged, the other sensing assembly 200 can still work, so that the aerosol generating device can still work, thereby improving the service life of the aerosol generating device and reducing waste.

[0046] In specific embodiments, with reference to FIGS. 3 to Figure 6As shown, the induction assembly 200 further comprises a connecting line 220, which comprises a first connecting line 221 and a second connecting line 222, and the first connecting line 221 and the second connecting line 222 are connected with two ends of the induction piece 210 respectively. Specifically, the induction assembly 200 further comprises the connecting line 220, which is used for transmitting the sensing signal generated by the induction piece to the atomization assembly 100; the connecting line 220 comprises the first connecting line 221 and the second connecting line 222, the first connecting line 221 is used for power supply, and one end of the first connecting line 221 is connected with one end of the induction piece 210; the second connecting line 222 is used for outputting a pressure signal, and one end of the second connecting line 222 is connected with the other end of the induction piece 210. In the embodiment, the induction piece 210 adopts a strain pressure sensing probe, therefore the first connecting line 221 is a positive electrode line of the strain pressure sensing probe, the second connecting line 222 is a negative electrode line of the strain pressure sensing probe, the first connecting line 221 is used as a power supply electrode lead of the strain pressure sensing probe, and the second connecting line 222 is used as an electrode lead for outputting a differential signal, which are connected with a resistance strain gauge made of a material with a temperature coefficient close to zero and a fixed resistance etched Res Bridge with a very small temperature coefficient, and the circuit senses whether the human lips are in contact with the atomizer, and sends a signal to a processor and a microcontroller through subsequent related circuits for collection, operation and processing. The structure is simple, and the connecting line 220 is connected with the atomization assembly 100 through the probe connecting point 416.

[0047] Specifically, the embodiment further provides an assembling method of the aerosol generating device, which comprises the following steps: firstly, welding the induction piece 210 and the connecting line 220 to form the induction assembly 200, then inserting the induction assembly 200 into the cover member 300, and finally assembling the atomization core 417 on the shell 412 of the aerosol generating device, wherein the connecting line 220 passes through the cartridge base 413 and the atomization core base 415, and is welded to the probe connecting point 416.

[0048] The above merely provides a specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can easily think of various equivalent modifications or replacements within the technical range disclosed by the present application, and these modifications or replacements should be covered in the protection scope of the present application.
