Therefore, other examples of the exemplary embodiments may have different values. It should be noted that: like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0062] Please refer to Figures 1 to 4 , one embodiment of the present application provides an atomizing device 100. The atomizing device 100 is used to atomize an aerosol-forming substrate to generate an aerosol for a user to inhale, so as to replace traditional cigarettes. The atomizing device 100 includes a housing 110, a mouthpiece assembly 120, a liquid storage assembly 130, an atomizing assembly 140, an airflow detection assembly 150, and a control assembly 160.

[0063] The mouthpiece assembly 120 is disposed at one end of the housing 110. The mouthpiece assembly 120 has an inhalation port 10. In this embodiment, the mouthpiece assembly 120 is located above the housing 110. During the use of the atomizing device 100, the atomized aerosol-forming substrate flows out from the inhalation port 10 for the user to inhale.

[0064] The liquid storage assembly 130 is disposed in the housing 110. The liquid storage assembly 130 is used to store the aerosol-forming substrate. The liquid storage assembly 130 is arranged such that the aerosol-forming substrate can come into contact with the atomizing assembly 140 to atomize the aerosol-forming substrate. In this embodiment, the aerosol-forming substrate comes into contact with the atomizing assembly 140 through capillary action to atomize the aerosol-forming substrate. And, since the liquid storage assembly 130 is disposed in the housing 110 and the mouthpiece assembly 120 is located above the housing 110, the mouthpiece assembly 120 is also located above the liquid storage assembly 130.

[0065] The atomization component 140 is also disposed within the housing 110. The atomization component 140 is connected to the liquid storage component 130. The atomization component 140 is configured to atomize the aerosol-forming substrate in the liquid storage component 130. It can be understood that there are various ways for the atomization component 140 to atomize the aerosol-forming substrate, including electrothermal atomization, ultrasonic atomization, or spray atomization, etc. Further, in the electrothermal atomization method, the heating method of the atomization component 140 can also be various, including resistance heating atomization, electromagnetic induction heating atomization, etc. Different atomization methods or heating methods can be selected according to actual needs.

[0066] The air flow detection component 150 is disposed within the mouthpiece component 120. An air passage is formed between the air flow detection component 150 and the suction port 10 of the mouthpiece component 120. The air flow detection component 150 is configured to detect the suction action of the suction port 10 of the mouthpiece component 120. In fact, an air flow sensor 151 is provided in the air flow detection component 150. Since an air passage is formed between the air flow detection component 150 and the suction port 10 of the mouthpiece component 120, when the user inhales at the suction port 10, the air flow movement in the air passage will generate a negative pressure on the surface of the air flow sensor 151. Since an induction diaphragm is usually provided inside the air flow sensor 151, when a negative pressure is generated on the surface of the air flow sensor 151, the induction diaphragm inside the air flow sensor 151 usually deforms, thereby generating an induction signal and sending it to the control component 160. In this way, the air flow detection component 150 can be used to detect the suction action generated by the user at the suction port 10 of the mouthpiece component 120.

[0067] The control component 160 is configured to control the atomization component 140 to atomize the aerosol-forming substrate in the liquid storage component 130 according to the suction action detected by the air flow detection component 150. During actual use, when the user inhales at the suction port 10 of the mouthpiece component 120, the air flow detection component 150 detects the user's inhalation action, generates an induction signal and sends it to the control component 160. The control component 160 receives the induction signal sent by the air flow detection component 150 and controls the atomization component 140 to operate, thereby atomizing the aerosol-forming substrate in the liquid storage component 130. For example, when the atomization component 140 is an electrothermal atomization component, the control component 160 can energize the heating wire in the atomization component 140, so that the heating wire generates heat to heat and atomize the aerosol-forming substrate.

[0068] Compared with traditional atomizing devices, since traditional atomizing devices generally set the air flow detection device below the liquid storage component, when the aerosol formation matrix leaks, the aerosol formation matrix will flow downward into the air flow detection device due to the action of gravity, resulting in the self-activation or damage of the air flow detection device. In severe cases, a fire may even occur, thus posing a great safety hazard. In the atomizing device 100 provided in the above embodiments, since the air flow detection component 150 is arranged in the mouthpiece component 120 and above the liquid storage component 130, when the aerosol formation matrix in the liquid storage component 130 leaks, due to the action of gravity, it generally flows towards the bottom of the atomizing device 100 and does not flow to the surface of the air flow detection component 150. That is, the structure of the atomizing device 100 can effectively prevent the self-activation or damage of the air flow detection component 150 caused by the leakage of the aerosol formation matrix, thereby improving the safety performance of the atomizing device 100.

[0069] Please also refer to Figures 5 to 7 , in some embodiments, the mouthpiece component 120 includes a mouthpiece cover 121, a mouthpiece housing 122, and a suction member 123. In this embodiment, the mouthpiece cover 121, the mouthpiece housing 122, and the suction member 123 are integrally formed.

[0070] The mouthpiece cover 121 is arranged on the housing 110.

[0071] The mouthpiece housing 122 extends downward from the periphery of the mouthpiece cover 121. The mouthpiece housing 122 wraps part of the housing 110. An interference fit relationship is formed between the mouthpiece housing 122 and the housing 110, so that the mouthpiece component 120 and the housing 110 are assembled together.

[0072] The suction member 123 includes a first tube body 1231 and a second tube body 1232. The first tube body 1231 is arranged around the second tube body 1232. The first tube body 1231 extends upward from the mouthpiece cover 121 to form a shape for the user to suck. The second tube body 1232 extends downward from the top position of the first tube body 1231 to form a first air passage L1 for the user to suck. In this embodiment, the air passage inside the second tube body 1232 is part of the air passage formed between the air flow detection component 150 and the suction port 10 of the mouthpiece component 120.

[0073] Specifically, a stepped portion 111 is provided on the side of one end of the housing 110 for setting the nozzle assembly 120. When the nozzle assembly 120 and the housing 110 are assembled together, a part of the housing 110 extends into the nozzle housing 122 of the nozzle assembly 120, so that the nozzle assembly 120 and the housing 110 are fixed together. The stepped portion 111 is provided for limiting the nozzle housing 122. It can be understood that the width of the stepped portion 111 corresponds to the width of the nozzle housing 122, so that when the nozzle assembly 120 and the housing 110 are assembled together, the side surface of the nozzle assembly 120 is flush with the housing 110. According to needs, a convex ring 112 can also be provided on the outer side surface of the housing 110, and the convex ring 112 is located at the part where the housing 110 extends into the nozzle housing 122. When the nozzle assembly 120 and the housing 110 are assembled together, the convex ring 112 provided on the outer side surface of the housing 110 can increase the friction between the nozzle housing 122 and the housing 110, so that the connection between the nozzle assembly 120 and the housing 110 is more stable. It can be understood that the nozzle assembly 120 and the housing 110 can also be connected by a snap connection. According to needs, a recessed portion 1211 can also be provided on the bottom surface of the nozzle cap 121. The recessed portion 1211 is used to form a part of the air passage formed between the airflow detection component 150 and the suction port 10 of the nozzle assembly 120.

[0074] Please refer to Figures 8 to 9 simultaneously. In some embodiments, the airflow detection component 150 includes a carrier seat 152 and an airflow sensor 151 provided on the carrier seat 152.

[0075] The carrier seat 152 is fixed inside the nozzle cap 121. A receiving cavity 1521 is provided inside the carrier seat 152.

[0076] The airflow sensor 151 is provided in the receiving cavity 1521 of the carrier seat 152. A second air passage L2 is formed between the airflow detection component 150 and the suction port 20 of the nozzle assembly 120.

[0077] In this embodiment, the first air passage L1 penetrates through the housing 110, the liquid storage component 130, and the atomization component 140. A first air inlet 118 is provided at the bottom end of the housing 110. During suction, air enters from the first air inlet 118, passes through the atomization component 140, the liquid storage component 130, and the housing 110, reaches the bottom end of the second tube body 1232, and then moves from the bottom end of the second tube body 1232 to the top end of the second tube body 1232.

[0078] The second air passage L2 is located inside the nozzle assembly 120. During suction, air flows from the airflow sensor 151 to the bottom end of the second tube body 1232, and then moves from the bottom end of the second tube body 1232 to the top end of the second tube body 1232;

[0079] The airflows in the first air passage L1 and the second air passage L2 are mixed inside the second tube body 1232.

[0080] In this embodiment, the atomizing device 100 further includes an air regulating assembly 180.

[0081] The air regulating assembly 180 is disposed on the first air inlet 118 of the housing 110. The air regulating assembly 180 is used to regulate the air intake of the atomizing device 100.

[0082] In this embodiment, the carrier seat 152 is made of silica gel. A receiving cavity 1521 is provided at a position close to the center of the carrier seat 152. The airflow sensor 151 is installed in the receiving cavity 1521. The top of the receiving cavity 1521 is of a hollow structure, so that the surface of the airflow sensor 151 communicates with the second air passage L2. As described above, an induction diaphragm is provided inside the airflow sensor 151. When negative pressure is generated on the surface of the airflow sensor 151, the induction diaphragm inside the airflow sensor 151 usually deforms, thereby generating an induction signal and sending it to the control assembly 160. Therefore, the induction surface of the airflow sensor 151 needs to communicate with the second air passage L2. During actual use, the size of the receiving cavity 1521 inside the carrier seat 152 can be set to be slightly smaller than the size of the airflow sensor 151. At this time, when the airflow sensor 151 is placed into the receiving cavity 1521 of the carrier seat 152, due to the elastic effect of the silica gel, the carrier seat 152 can fix the airflow sensor 151 well inside it. According to needs, a second convex ring can also be provided on the inner side surface of the receiving cavity 1521. The second convex ring protrudes inward. When the airflow sensor 151 is placed into the receiving cavity 1521 of the carrier seat 152, the second convex ring can also fix the airflow sensor 151 well.

[0083] In some embodiments, the carrier base 152 is further provided with a receiving groove 1522. The receiving groove 1522 is located around the receiving cavity 1521. When the airflow sensor 151 is disposed inside the receiving cavity 1521, the electrodes of the airflow sensor 151 extend into the receiving groove 1522. In this embodiment, the number of the receiving grooves 1522 is two. The two receiving grooves 1522 are respectively used for disposing the positive electrode and the negative electrode of the airflow sensor 151.

[0084] Please refer to Figures 10 to 11 simultaneously. In this embodiment, a first electrode 1111 is disposed on the top of the housing 110. The first electrode 1111 is used to supply power to the airflow sensor 151. When the housing 110 and the nozzle assembly 120 are assembled together, the first electrode 1111 extends into the receiving groove 1522 and makes electrical contact with the electrodes of the airflow sensor 151. Specifically, there are two first electrodes 1111, which are respectively connected to the positive and negative poles of the power supply. When the housing 110 and the nozzle assembly 120 are assembled together, the first electrode 1111 can be inserted into the receiving groove 1522. Since the electrodes of the airflow sensor 151 also extend into the receiving groove 1522, at this time, due to the mutual extrusion between the first electrode 1111 and the electrodes of the airflow sensor 151, good electrical contact characteristics can be formed between the two.

[0085] In some embodiments, the nozzle assembly 120 includes a first magnetic member 124, and the housing 110 includes a second magnetic member 113.

[0086] When the nozzle assembly 120 and the housing 110 are assembled together, the first magnetic member 124 and the second magnetic member 113 attract each other to fix the nozzle assembly 120 and the housing 110 together.

[0087] In this embodiment, by providing the first magnetic member 124 on the nozzle assembly 120 and the second magnetic member 113 on the housing 110, since the positions of the first magnetic member 124 and the second magnetic member 113 correspond to each other, when the nozzle assembly 120 and the housing 110 are assembled together, the first magnetic member 124 and the second magnetic member 113 attract each other to fix the nozzle assembly 120 and the housing 110 together. The provision of the first magnetic member 124 and the second magnetic member 113 makes the assembly and disassembly of the nozzle assembly 120 and the housing 110 more convenient. In this embodiment, a plurality of fixing columns are disposed on the bottom surface of the nozzle cover 121 for fixing the first magnetic member 124.

[0088] According to requirements, the number of the first magnetic attraction member 124 and the second magnetic attraction member 113 can be multiple to facilitate the disassembly and assembly of the nozzle assembly 120 and the housing 110. In this embodiment, the number of the first magnetic attraction members 124 is set to 4, and they are arranged on the lower surface of the nozzle cover 121. Specifically, two of the first magnetic attraction members 124 are arranged on one side of the first tube body 1231, and the other two first magnetic attraction members 124 are arranged on the other side of the second tube body 1231. Specifically, a clearance hole 1523 is further arranged on the carrier seat 152 of the airflow detection assembly 150, and the fixing posts on the bottom surface of the nozzle cover 121 pass through the clearance hole 1523 on the carrier seat 152, so that the first magnetic attraction member 124 and the second magnetic attraction member 113 are attracted to each other. By arranging the clearance hole 1523 on the carrier seat 152, the fixing posts provided with the first magnetic attraction members 124 can well pass through the clearance hole 1523, so that the first magnetic attraction member 124 and the second magnetic attraction member 113 are attracted to each other. On the other hand, the clearance hole 1523 can also play a role in positioning, so that the carrier seat 152 can be accurately fixed at the corresponding position of the nozzle cover 121.

[0089] Similarly, in some embodiments, the nozzle assembly 120 includes a third magnetic attraction member 125; the carrier seat 152 includes a fourth magnetic attraction member 1524.

[0090] When the nozzle assembly 120 and the airflow detection assembly 150 are assembled together, the third magnetic attraction member 125 and the fourth magnetic attraction member 1524 attract each other to fix the carrier seat 152 of the nozzle assembly 120 and the airflow detection assembly 150 together.

[0091] In this embodiment, by arranging the third magnetic attraction member 125 on the nozzle assembly 120 and the fourth magnetic attraction member 1524 on the carrier seat 152 of the airflow detection assembly 150, since the positions of the third magnetic attraction member 125 and the fourth magnetic attraction member 1524 correspond to each other, when the nozzle assembly 120 and the carrier seat 152 of the airflow detection assembly 150 are assembled together, the third magnetic attraction member 125 and the fourth magnetic attraction member 1524 attract each other to fix the nozzle assembly 120 and the airflow detection assembly 150 together. The arrangement of the third magnetic attraction member 125 and the fourth magnetic attraction member 1524 makes the assembly and disassembly of the nozzle assembly 120 and the airflow detection assembly 150 more convenient.

[0092] Please also refer to Figure 11 that, in some embodiments, the atomization assembly 140 includes a liquid guiding member 141 and a heating element 142 arranged on the liquid guiding member 141.

[0093] The liquid guiding member 141 is in contact with the liquid storage assembly 130. The liquid guiding member 141 is used to suck the aerosol forming matrix from the liquid storage assembly 130.

[0094] The heating element 142 is disposed on the liquid guiding member 141. After the heating element 142 is energized, it generates heat to heat the aerosol forming matrix in the liquid guiding member 141 to generate the aerosol for inhalation.

[0095] In this embodiment, the liquid guiding member 141 has a cylindrical structure. The liquid guiding member 141 seals the opening position of the liquid storage assembly 130, thereby sucking the aerosol forming matrix from the liquid storage assembly 130. The heating element 142 is a resistance heating wire, which is wound into a spiral shape and disposed on the inner wall surface of the cylindrical liquid guiding member 141. After the heating element 142 is energized, it generates heat to heat the aerosol forming matrix in the liquid guiding member 141 to generate the aerosol for inhalation.

[0096] In some embodiments, the housing 110 further includes a liquid storage chamber 114 and a battery chamber 115.

[0097] The liquid storage chamber 114 is used to accommodate the liquid storage assembly 130.

[0098] The battery chamber 115 is used to accommodate the power supply assembly 170.

[0099] A partition 116 is formed between the liquid storage chamber 114 and the battery chamber 115. The partition 116 is used to separate the liquid storage chamber 114 and the battery chamber 115 into two independent spaces.

[0105] It can be understood that the atomization device provided in this application is not limited to the above embodiments.

[0106] Please refer to Figure 12 , another embodiment of this application provides an atomization device 200. The atomization device 200 is used to atomize an aerosol-forming substrate to generate an aerosol for users to inhale, so as to replace traditional cigarettes. The atomization device 200 includes a housing 210, a mouthpiece component 220, a liquid storage component 230, an atomization component 240, an air flow detection component 250, a control component 260, and a power supply component 270.

[0107] In this embodiment, the shapes and structures of the housing 210, the mouthpiece component 220, the liquid storage component 230, the air flow detection component 250, the control component 260, and the power supply component 270 are similar to those in the previous embodiment, and will not be elaborated here.

[0108] The atomization component 240 includes a liquid guiding member 241 and a heating element 242 arranged on the liquid guiding member 241.

[0109] The liquid guiding member 241 is in contact with the liquid storage component 230. The liquid guiding member 241 is used to suck the aerosol-forming substrate from the liquid storage component 230.

[0110] The heating element 242 is disposed on the liquid guiding member 241. After the heating element 242 is energized, it generates heat to heat the aerosol forming matrix in the liquid guiding member 241 to generate an aerosol for inhalation.

[0111] The mouthpiece assembly 220 includes a mouthpiece cover 221, a mouthpiece housing 222, and an inhalation member 223.

[0112] The mouthpiece cover 221 is disposed on the housing 210.

[0113] The mouthpiece housing 222 extends downward from the periphery of the mouthpiece cover 221. The mouthpiece housing 222 encloses a part of the housing 210. An interference fit relationship is formed between the mouthpiece housing 222 and the housing 210, so that the mouthpiece assembly 220 and the housing 210 are assembled together.

[0114] The inhalation member 223 is disposed above the mouthpiece cover 221. The inhalation member 223 includes a first tube body 2231 and a second tube body 2232. The first tube body 2231 is disposed around the second tube body 2232. The first tube body 2231 extends upward from the mouthpiece cover 221 to form a shape for the user to suck. The second tube body 2232 extends downward from the top position of the first tube body 2231 to form an air passage for the user to suck.

[0115] Different from the previous embodiment, in this embodiment, the liquid guiding member 241 includes a first liquid guiding portion 2411 and a second liquid guiding portion 2412.

[0116] The first liquid guiding portion 2411 is disposed inside the mouthpiece assembly 220. The heating element 242 is disposed on the first liquid guiding portion 2411 of the liquid guiding member 241.

[0117] The second liquid guiding portion 2412 includes a first end and a second end. The first end of the second liquid guiding portion 2412 is connected to the first liquid guiding portion 2411. The second end of the second liquid guiding portion 2412 passes through the housing 210 and is connected to the liquid storage assembly 230. The aerosol forming matrix in the liquid storage assembly 230 is transmitted to the first liquid guiding portion 2411 through the second liquid guiding portion 2412.

[0118] In the atomizing device 200 provided in this embodiment, by dividing the liquid guiding member 241 into a first liquid guiding portion 2411 and a second liquid guiding portion 2412, the first liquid guiding portion 2411 is disposed inside the mouthpiece assembly 220 and is used to dispose the heating element 242, and the second liquid guiding portion 2412 passes through the housing 210 and is connected to the liquid storage assembly 230, and transfers the absorbed aerosol forming matrix to the first liquid guiding portion 2411. At this time, the setting position of the atomizing assembly 240 is more free. According to needs, an air inlet may also be provided in the mouthpiece assembly 220. When the user sucks, air enters from the air inlet of the mouthpiece assembly 220, mixes with the aerosol in the atomizing assembly 240, and then flows out from the suction port 20 of the mouthpiece assembly 220.

[0119] In this embodiment, the first liquid guiding portion 2411 is disposed on the second tube body 2231 of the inhalation member 223 of the mouthpiece assembly 220.

[0120] According to needs, an air circulation hole is formed at the connection between the first liquid guiding portion 2411 and the second liquid guiding portion 2412. When the atomizing device 200 is working, air enters the atomizing assembly 240 from the air circulation hole, mixes with the atomized aerosol forming matrix, and then flows out from the suction port 20 of the mouthpiece assembly 220 through the channel inside the second tube body 2231.

[0121] For the sake of convenience of description, spatial relative terms such as "above...", "over...", "on the upper surface of...", "above" and the like can be used here to describe the spatial position relationship between a device or feature shown in the figure and other devices or features. It should be understood that the spatial relative terms are intended to include different orientations in use or operation in addition to the orientation described in the figure of the device. For example, if the device in the figure is inverted, the device described as "above other devices or structures" or "over other devices or structures" will be positioned as "below other devices or structures" or "under other devices or structures" afterwards. Thus, the exemplary term "above..." can include both orientations of "above..." and "below...". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding explanations are made for the spatial relative descriptions used here.
