When theatomizer 10 is electrically connected to thepower supply device 20, theatomizer 10 heats the aerosol-forming substrate under the electric drive of thepower supply device 20 to atomize the aerosol-forming substrate into smoke. - It should be noted that “axial direction” refers to the connection direction of the
atomizer 10 and thepower supply device 20, “radial direction” refers to a direction perpendicular to the “axial direction”. “Lower end” refers to the end of each component or part of theatomizer 10 that is close to thepower supply device 20 in the axial direction of theatomizer 10. “Upper end” refers to the end of each component or part of theatomizer 10 that is away from thepower supply device 20 in the axial direction of theatomizer 10. “Upper end surface” refers to the flat and/or curved surface of the upper end, “lower end surface” refers to the flat and/or curved surface of the lower end. - An airflow passage is formed inside the
atomizer 10. Thepower supply device 20 includes a power supplymain body 21 and asensor 23. Asensing passage 2111, afiltering chamber 2112 and acommunication hole 2121 are provided in the power supplymain body 21. Thesensing passage 2111 is separated from thefiltering chamber 2112, and thecommunication hole 2121 communicates with thesensing passage 2111 and thefiltering chamber 2112. Thesensor 23 is disposed in thesensing passage 2111, thesensor 23 is configured to detect the physical characteristics and suction signals of the gas in thesensing passage 2111. One end of the power supplymain body 21 is provided with a connecting end, the connecting end is configured to connect with theatomizer 10. A throughhole 221 is provided through the connecting end, the throughhole 221 communicates with thefiltering chamber 2112 and the airflow passage, thefiltering chamber 2112 is configured for preventing solids and/or liquids from entering thesensing passage 2111 through thecommunication hole 2121. - In this embodiment, the power supply
main body 21 includes ahousing 211, and a sealingmember 22 and abracket 212 provided in thehousing 211. A controller electrically connected to thesensor 23 is provided in thehousing 211. The sealingmember 22 is the connecting end, and the throughhole 221 is provided through the sealingmember 22. Thesensing passage 2111 is provided inside thebracket 212. Thebracket 212 is arranged between the sealingmember 22 and thesensor 23. Thecommunication hole 2121 is provided through thebracket 212, thecommunication hole 2121 is staggered from the throughhole 221 in the axial direction of theatomizer 10. Thefiltering chamber 2112 is formed by the space between thebracket 212 and the sealingmember 22, thereby preventing solids and/or liquids from flowing into thesensing passage 2111 from thecommunication hole 2121. - It can be understood that, in another embodiment not shown, the arrangement positions of the sealing
member 22 and thebracket 212 can be interchanged, That is, thebracket 212 is the connecting end, the throughhole 221 is provided through thebracket 212, thesensing passage 2111 is provided inside the sealingmember 22, the sealingmember 22 is arranged between thebracket 212 and thesensor 23, and thecommunication hole 2121 is provided through the sealingmember 22. - Specifically, when the
atomizer 10 heats the aerosol-forming substrate, the temperature of the smoke formed by theatomizer 10 heating the aerosol-forming substrate is relatively high, and some of the smoke may not be sucked out. After theatomizer 10 stops heating the aerosol-forming substrate, the atomized smoke gradually cools and is liquefied to generate aerosol-forming substrate during the long-term placement of theatomizer 10, and the aerosol-forming substrate may leak out of theatomizer 10 through the airflow passage. Alternatively, when theatomizer 10 heats the aerosol-forming substrate, the viscosity of the aerosol-forming substrate decreases when heated; after theatomizer 10 stops heating the aerosol-forming substrate, the aerosol-forming substrate that has not been atomized remains in theatomizer 10, and the aerosol-forming substrate may leak out of theatomizer 10 through the airflow passage. Alternatively, the aerosol-forming substrate in theatomizer 10 may leak out of theatomizer 10 through a poorly sealed location. The aerosol-forming substrate leaked out of theatomizer 10 may leak into thepower supply unit 20 through the airflow passage, after thesensing passage 2111 is blocked by the aerosol-forming substrate, the normal operation of thepower supply device 20 will be affected, thereby affecting the use by the user. - Specifically, in one embodiment, a filter element is provided in the
filtering chamber 2112, the filter element is made of cotton or cotton cloth or other materials that are easy to intercept solids and/or liquids. - Specifically, the
sensing passage 2111 is configured to conduct the physical characteristics and suction signals of the gas to thesensor 23, wherein the physical characteristics and suction signals of the gas include but are not limited to airflow or air pressure. When thesensor 23 detects the physical characteristics and suction signals of the gas, thepower supply 24 in thepower supply device 20 supplies power to theatomizer 10. Specifically, anatomizing chamber 173 that communicates with the throughhole 221 and asmoke outlet passage 12 that communicates between the atomizingchamber 173 and the outside environment are provided in theatomizer 10. Thesensor 23 is a pressure sensor, the air in thesensing passage 2111 is at least partially sucked out under the action of suction, the air pressure in thesensing passage 2111 decreases, and the pressure sensor senses this air pressure change, generates a trigger signal and sends it to the controller, such that the controller receives the trigger signal and controls thepower supply 24 to supply power to theatomizer 10. - It can be understood that, in another embodiment, the
sensor 23 is an airflow sensor. Specifically, thehousing 211 is provided with a ventilation hole that communicates with the outside environment, the outside air flows into thesensing passage 2111 through the ventilation hole under the action of suction, the airflow in thesensing passage 2111 passes through the airflow sensor, the airflow sensor generates an airflow signal after sensing the airflow change, and after the airflow signal is transmitted to the controller, the controller controls thepower supply 24 to supply power to theatomizer 10. - To sum up, since the
sensing passage 2111 is separated from thefiltering chamber 2112, thecommunication hole 2121 communicates with thesensing passage 2111 and thefiltering chamber 2112, the throughhole 221 is provided through the connecting end, the throughhole 221 communicates with thefiltering chamber 2112 and the airflow passage, thefiltering chamber 2112 can prevent solids and/or liquids from entering thesensing passage 2111 through thecommunication hole 2121. Therefore, when the solids and/or liquids fall from the airflow passage, the solids and/or liquids in theaerosol generating device 100 can be prevented from flowing into thesensing passage 2111 through thefiltering chamber 2112; thus, the solids and/or liquids are prevented from flowing into thesensing passage 2111 and contacting with thesensor 23 to cause the circuit of thesensor 23 to be short-circuited, thereby improving the service life of thesensor 23. - In this embodiment, the sealing
member 22 is the connecting end used to connect with theatomizer 10, the sealingmember 22 is configured to seal the opening of thepower supply device 20 and divide thepower supply device 20 into the inside of thepower supply device 20 and the outside of thepower supply device 20. The inside of thepower supply device 20 is configured to place components such as thesensor 23 and the controller, and the outside of thepower supply device 20 is configured to connect with theatomizer 10. Specifically, the side wall of the sealingmember 22 abuts against the inner wall of thehousing 211, such that the sealingmember 22 is fixed in thehousing 211. In addition, through the tight fit between the side wall of the sealingmember 22 and the inner wall of thehousing 211, the gap between the two can be sealed to prevent the aerosol-forming substrate from flowing into the interior of thepower supply device 20 through the gap and affecting the use of the aerosol-generatingdevice 100. Specifically, the sealingmember 22 is made of a material with good sealing properties such as silicone or rubber. It can be understood that, in another embodiment, the sealingmember 22 can also be integrally formed with thehousing 211. - In one embodiment, the
bracket 212 is provided with abarrier wall 2125, thebarrier wall 2125 includes a first limitingportion 2122 and a second limitingportion 2123, the first limitingportion 2122 and the second limitingportion 2123 protrude upward from thebracket 212. The space between the first limitingportion 2122 and the second limitingportion 2123 forms aliquid storage cavity 2124. Theliquid storage cavity 2124 is aligned with the throughhole 221 in the axial direction of theatomizer 10. When the user holds theaerosol generating device 100 in a normal direction (i.e., thepower supply device 20 is located under the atomizer 10), the aerosol-forming substrate in theaerosol generating device 100 can flow into theliquid storage cavity 2124 through the throughhole 221. Thus, the aerosol-forming substrate in theliquid storage cavity 2124 can be cleaned by separating theatomizer 10 from thepower supply device 20, which is convenient to operate. - Specifically, the first limiting
portion 2122 and the second limitingportion 2123 are provided on the upper end surface of thebracket 212. The first limitingportion 2122 and the second limitingportion 2123 are formed by protruding upward along the axial direction of thehousing 211. The first limitingportion 2122 and the second limitingportion 2123 are integrally formed with thebracket 212. It can be understood that, in another embodiment, both the first limitingportion 2122 and the second limitingportion 2123 are detachably connected to thebracket 212, and the detachable connection includes but is not limited to snapping connection or plugging connection. - Specifically, an upper end of the
bracket 212 is provided with anupper plate 2120 located, between the sealingmember 22 and thesensor 23. The first limitingportion 2122 and the second limitingportion 2123 protrude upward from theupper plate 2120 toward the sealingmember 22. Thecommunication hole 2121 is provided through theupper plate 2120. Thesensing passage 2111 and thefiltering chamber 2112 are communicated with each other through thecommunication hole 2121. Theliquid storage cavity 2124 is formed by a space between theupper plate 2120, the first limitingportion 2122 and the second limitingportion 2123. Theliquid storage cavity 2124 is aligned with the throughhole 221 in the axial direction of theatomizer 10 and is located directly under the throughhole 221, and thecommunication hole 2121 is located at one side of theliquid storage cavity 2124 and is therefore staggered from the throughhole 221 in the axial direction of theatomizer 10. - It can be understood that, in another embodiment not shown, a liquid absorbing element is provided in the
liquid storage cavity 2124, and the liquid absorbing element is used for absorbing the aerosol-forming substrate. The liquid absorbing element is made of a material with good adsorption properties such as cotton or cotton cloth. - In one embodiment, the
bracket 212 is detachably connected to thehousing 211 by means of snapping connection or plugging connection. In addition, in order to improve the connection stability, when thebracket 212 is connected to thehousing 211, thebracket 212 can also be fixedly connected to the sealingmember 22, and the fixed connection includes but is not limited to snapping connection or plugging connection. It can be understood that, in another embodiment, thebracket 212 and thehousing 211 are integrally formed. - In one embodiment, the
power supply device 20 further includes a USB (universal serial bus) chargingstructure 25 provided on thehousing 211 and a PCB (printed circuit board) provided in thehousing 211. TheUSB charging structure 25 and the PCB are electrically connected to thepower source 24. The controller is mounted on the PCB. Specifically, the charging interface in theUSB charging structure 25 passes through thehousing 211 and extends to the outside environment. When the charging interface is activated, thepower supply device 20 can be charged through the charging interface. It can be understood, in another embodiment, thesensing passage 2111 is in communication with the charging interface, thesensor 23 is a differential pressure sensor; under the action of suction, one side of thesensing passage 2111 facing thesmoke outlet passage 12 generates negative pressure, and the other side of thesensing passage 2111 facing the USB interface is at normal pressure. As a result, a pressure difference is generated at opposite sides of the differential pressure sensor, thereby generating a suction signal, and then the suction signal is transmitted to the controller, and the controller controls thepower supply 24 to supply power to theatomizer 10. When the user stops sucking, because thesensing passage 2111 is connected to the outside environment, the air pressure in thesensing passage 2111 is restored, thesensor 23 senses the restoration of the air pressure, and then generates a shutdown signal and sends it to the controller, the controller receives the shutdown signal and controls thepower supply 24 to stop supplying power to theatomizer 10. - In one embodiment, in order to improve the air tightness of the
sensor 23, asensor sealing member 26 is sleeved on thesensor 23, and thesensor sealing member 26 is made of a material with good sealing performance such as silicone or rubber. - The upper end of the
housing 211 is at least partially and detachably sleeved on the outside of theatomizer 10, so that thepower supply device 20 and theatomizer 10 are detachably connected. The detachable connection includes but is not limited to snapping connection or plugging connection. Thehousing 211 is provided with an air inlet hole that communicates with the outside environment. Theatomizer 10 includes aliquid storage assembly 101 and anatomizing assembly 102 provided with theatomizing chamber 173. Theliquid storage assembly 101 includes aliquid storage member 13 and a ventingmember 14 provided in theliquid storage member 13.

Thesmoke outlet passage 12 communicates with theatomizing chamber 173 and thesmoke outlet hole 132. Theatomizing assembly 102 can heat the aerosol-forming substrate flowing into theatomizing chamber 173 under the electric drive of thepower supply device 20, and the smoke generated by heating the aerosol-forming substrate is mainly filled in theatomizing chamber 173. - Specifically, the
smoke outlet hole 132 is provided at the upper end of theliquid storage member 13. The inner wall of theliquid storage member 13 extends downward along the axial direction of theliquid storage member 13 to form the ventingmember 14 located around thesmoke outlet hole 132. The ventingmember 14 and theliquid storage member 13 are integrally formed. It can be understood that, in another embodiment, the ventingmember 14 and theliquid storage member 13 are detachably connected by means of snapping connection or plugging connection. - In one embodiment, the
liquid storage member 13 is pre-packaged, i.e., the aerosol-forming substrate is pre-injected into theliquid storage chamber 131. After the aerosol-forming substrate is consumed up, the user can discard theliquid storage assembly 101 separately, because theliquid storage assembly 101 cannot be refilled with liquid. - The
atomizing assembly 102 includes an atomizingupper cover 15 disposed in theliquid storage member 13, a base 16 located under the atomizingupper cover 15 and connected with theliquid storage member 13, and aheating structure 17 installed on thebase 16. Theheating structure 17 includes aliquid absorbing member 171 and aheating member 172, and theheating member 172 is in contact with theliquid absorbing member 171. - In one embodiment, the lower end of the
liquid storage member 13 is an open end. The side wall of the atomizingupper cover 15 abuts against the inner wall of theliquid storage chamber 131 to seal the open end of theliquid storage member 13. The atomizingupper cover 15 is provided with at least oneliquid guiding hole 151 communicating with theatomizing assembly 102 and theliquid storage chamber 131. It can be understood that, in another embodiment, the atomizingupper cover 15 can also be integrally formed with theliquid storage member 13. - In one embodiment, the
base 16 and theliquid storage member 13 are detachably connected by means of snapping connection or plugging connection. It can be understood that, in another embodiment, thebase 16 and theliquid storage member 13 are integrally formed. - In one embodiment, in order to improve the connection stability between the atomizing
upper cover 15 and theliquid storage member 13, thebase 16 is further detachably connected with the atomizingupper cover 15, and the detachable connection includes but is not limited to snapping connection or plugging connection and so on. For example, in this embodiment, thebase 16 is snap-connected to the atomizingupper cover 15. It can be understood that, in another embodiment, thebase 16 and the atomizingupper cover 15 can also be integrally formed. - After the
power supply device 20 and theatomizer 10 are connected, the sealingmember 22 is located under thebase 16. Thebase 16 is provided with a flow-guidinghole 161 communicating with theatomizing chamber 173 and the throughhole 221. Twoelectrode contact members 162 are arranged on the base 16 at intervals, one end of each of the twoelectrode contact members 162 is electrically connected to one of the two pins of theheating member 172, the other end of each of the twoelectrode contact members 162 is electrically connected to one of the positive and negative electrodes of thepower supply device 20. Specifically, the twoelectrode contact members 162 are both made of conductive materials such as iron, cobalt or nickel, wherein one of theelectrode contact members 162 is used as a positive contact, and the otherelectrode contact member 162 is used as a negative contact. - In one embodiment, a sealing
ring 163 is sleeved on eachelectrode contact member 162 to prevent the aerosol-forming substrate in theatomizer 10 from leaking to the outside environment, and further prevent the aerosol-forming substrate in theatomizer 10 from flowing to theelectrode contact member 162, to improve the connection stability between theelectrode contact members 162 and thepower supply device 20. - The
heating member 172 may be disposed outside theliquid absorbing member 171 and/or inside theliquid absorbing member 171. When the aerosol-forming substrate in theliquid storage chamber 131 flows to theliquid absorbing member 171 through theliquid guiding hole 151, theliquid absorbing member 171 can gradually absorb the aerosol-forming substrate in theliquid storage chamber 131 and conduct the absorbed aerosol-forming substrate to theheating member 172. Theheating member 172 is electrically connected to thepower supply device 20. Theheating member 172 is electrically driven by thepower supply device 20 to heat the aerosol-forming substrate. The space in which theheating member 172 heats and atomizes the aerosol-forming substrate is theatomizing chamber 173. During suction, the outside air flows into theatomizing chamber 173 through the air inlet hole and the flow-guidinghole 161 in sequence to mix with the smoke, the smoke mixed with the air can flow out through thesmoke outlet passage 12 and thesmoke outlet hole 132 in sequence, so as to be sucked by the user. In this embodiment, the airflow passage is a passage constituted by the air inlet hole, the flow-guidinghole 161, theatomizing chamber 173, thesmoke outlet passage 12 and thesmoke outlet hole 132. - The
liquid absorbing member 171 may be made of a porous material with a fixed shape and liquid-conducting ability. In one embodiment, theliquid absorbing member 171 is made of a porous ceramic material. Theliquid absorbing member 171 made of porous ceramic material has many interconnected capillary pores. When the aerosol-forming substrate in theliquid storage chamber 131 is in contact with theliquid absorbing member 171, the aerosol-forming substrate is conducted along the surface of theliquid absorbing member 171. Specifically, when the surface of theliquid absorbing member 171 is permeated by the aerosol-forming substrate, theliquid absorbing member 171 will generate capillary action to absorb the aerosol-forming substrate to move into the capillary pores, thereby conducting the aerosol-forming substrate to theheating member 172. It can be understood that, in another embodiment, theliquid absorbing member 171 can also be made of a material that is easy to absorb liquid, such as cotton or cotton cloth. - The
heating member 172 may be made of any material with electrical conductivity, such as stainless steel or nichrome. In one embodiment, theheating member 172 is a heating sheet, and theheating member 172 is disposed on the lower end surface of theliquid absorbing member 171 by sintering. Specifically, theliquid absorbing member 171 is made by printing the resistive paste in the ceramic body and then laminating and sintering by hot pressing. Theheating member 172 is a printed resistive layer at the lower end surface of theliquid absorbing member 171. Since theheating member 172 is closely attached to theliquid absorbing member 171, the contact area between theheating member 172 and theliquid absorbing member 171 is improved. Further, since the contact area between theheating member 172 and theliquid absorbing member 171 is increased, theliquid absorbing member 171 can transmit the aerosol-forming substrate to theheating member 172 in time, to prevent theheating member 172 and theliquid absorbing member 171 from drying out due to small contact area. In addition, since theheating member 172 is sintered into the lower end surface of theliquid absorbing member 171, the assembly gap between theheating member 172 and theliquid absorbing member 171 is eliminated. The aerosol-forming substrate is prevented from accumulating in the gap, thereby preventing theheating member 172 from being unable to heat the aerosol-forming substrate accumulated in the gap in time, and accordingly preventing oil splashing. - In one embodiment, a
liquid sealing member 18 is sandwiched between the atomizingupper cover 15 and theheating structure 17. Theliquid sealing member 18 can improve the sealing between the atomizingupper cover 15 and theheating structure 17. Further, theliquid sealing member 18 can make theheating structure 17 evenly stressed and not easy to fail. In addition, theliquid sealing member 18 can also prevent rigid contact between the atomizingupper cover 15 and theheating structure 17 to affect the service life. Specifically, theliquid sealing member 18 is made of a material with good sealing properties such as silicone or rubber. - In the
power supply device 20 of the present disclosure and theaerosol generating device 100 having thepower supply device 20, since thesensing passage 2111 is separated from thefiltering chamber 2112, thecommunication hole 2121 communicates with thesensing passage 2111 and thefiltering chamber 2112, the throughhole 221 is provided through the connecting end, and the throughhole 221 communicates with thefiltering chamber 2112 and the airflow passage, thefiltering chamber 2112 can intercept solids and/or liquids from entering thesensing passage 2111 through thecommunication hole 2121; therefore, when the solids and/or liquids fall from the airflow passage, the solids and/or liquids in theaerosol generating device 100 can be prevented from flowing into thesensing passage 2111 through thefiltering chamber 2112, so as to prevent the solids and/or liquids from flowing into thesensing passage 2111 and contacting with thesensor 23 to cause the circuit of thesensor 23 to be short-circuited, thereby improving the service life of thesensor 23. - The above-mentioned embodiments merely represent several implementations of the present disclosure, and the descriptions thereof are specific and detailed, but they shall not be understood as a limitation on the scope of the present disclosure. It should be noted that, for those of ordinary skill in the art, variations and improvements may still be made without departing from the concept of the present disclosure, and all of which shall fall into the protection scope of the present disclosure. Therefore, the scope of protection of the present disclosure shall be subject to the appended claims.
