[0041] Specifically, the bracket 22 has a connecting portion 30, a accommodating chamber 221 and a fixing frame (not shown). The connecting portion 30 is arranged at one end of the bracket 22 close to the atomizing assembly 1, and is used to connect the atomizing assembly 1. The accommodating chamber 221 is arranged on the side of the connecting portion 30 away from the atomizing assembly 1, and the airflow sensor 23 and the control board 24 are arranged in the accommodating chamber 221. The fixing frame is arranged on the side of the accommodating chamber 221 away from the connecting portion 30, and is used to fix the battery 25.

That is, the start air passage 26 is used to connect the air flow sensor 23 with the atomizer assembly 1, and when the user inhales through the mouthpiece 124, the air flow sensor 23 in the start air passage 221 can detect the air pressure change or flow velocity change of the air flow in the air inlet passage of the atomizer assembly 1, and transmit a signal to the control board 24 to control the operation of the atomizer assembly 1.

[0044] A silicone seat 222 is provided at one end of the accommodating cavity 221 close to the atomizer assembly 1, and the silicone seat 222 is located at one end of the control board 24 and the airflow sensor 23 away from the battery 25, so as to prevent liquid from leaking into the control board 24 or the airflow sensor 23 through the gap of the bracket 22, thereby avoiding damage to the control board 24 and the airflow sensor 23 caused by liquid leakage.

[0045] The bracket 22 has a connecting portion 30 for connecting to the atomizer assembly 1, and a groove 31 is provided on the side of the connecting portion 30 facing the atomizer assembly 1.

Among them, the positive electrode cooperates with the third protrusion 313 to form an electrode contact member 50, and the negative electrode cooperates with the fourth protrusion 314 to form another electrode contact member 50; that is, two electrode contacts 50 are arranged on the bottom wall of the groove 31 for electrical connection with the atomizer assembly 1. The materials of the third protrusion 313 and the fourth protrusion 314 are insulating.

[0048] A protrusion 34 is also provided on the bottom wall of the groove 31, and a third through hole 341 is provided on the protrusion 34, and the third through hole 341 penetrates the bottom wall of the groove 31 and the part corresponding to the protrusion 34, as a part of the start airway 26. That is, the port of the start airway 26 away from the airflow sensor 23 is arranged in the groove 31, that is, the port of the start airway 26 away from the airflow sensor 23 is arranged on the bracket 22. One end of the start airway 26 is connected to the airflow sensor 23, and the other end is connected to the receiving portion 211; the port of the third through hole 341 away from the bottom wall of the groove 31 is the port of the start airway 26 away from the airflow sensor 23. That is, the port of the start airway 26 away from the airflow sensor 23 is higher than the bottom wall of the groove 31. A shielding portion 40 is provided on the side of the bottom wall of the groove 31 away from the port of the starting air duct 26 away from the airflow sensor 23, that is, a shielding portion 40 is provided between the port of the starting air duct 26 away from the airflow sensor 23 and the atomization assembly 1, which is used to prevent leakage of the atomization assembly 1 from directly entering the port of the starting air duct 26 away from the airflow sensor 23.

[0049] The first protrusion 311 , the second protrusion 312 , the third protrusion 313 , the fourth protrusion 314 , the raised portion 34 and the groove 31 may be integrally formed or fixed together by adhesive or other methods.

[0050] In this embodiment, the protrusion 34 is arranged close to the side wall of the groove 31, and the port of the third through hole 341 away from the bottom wall of the groove 31 is lower than the side wall of the groove 31; the shielding portion 40 is an extension portion 41 of the side wall of the groove 31, and the extension portion 41 extends from the side wall of the groove 31 to above the port of the start-up air passage 26 away from the airflow sensor 23 and covers the port of the start-up air passage 26 away from the airflow sensor 23. That is, the projection of the extension portion 41 on the plane where the port of the start-up air passage 26 away from the airflow sensor 23 is located completely covers the port of the start-up air passage 26 away from the airflow sensor 23.

[0051] Since the atomizer assembly 1 is inserted into the receiving portion 211 along the length direction of the shell 21, the leaked liquid in the atomizer assembly 1 flows out along the length direction of the shell 21. The port of the start airway 26 away from the airflow sensor 23 is perpendicular to the length direction of the shell 21. By providing a shielding portion 40 on the side wall of the groove 31, the shielding portion 40 covers the port of the start airway 26 away from the airflow sensor 23, so that the leaked liquid cannot vertically enter the start airway 26, thereby preventing the leaked liquid from blocking the start airway 221, and avoiding the influence of the leaked liquid on the start of the electronic atomizer device as much as possible.

[0052] Specifically, there is a gap between the extension 41 and the port of the starter airway 26 away from the airflow sensor 23. The shape of the extension 41 can be a rectangle or a circle or other shapes, that is, the extension 41 can be a rectangular plate, a circular plate or other structures, as long as the projection of the extension 41 on the plane where the port of the starter airway 26 close to the atomizer assembly 1 is located can completely cover the port of the starter airway 26. The extension 41 and the side wall of the groove 31 can be integrally formed, or can be fixedly connected by other means such as gluing, screwing, etc., as long as the extension 41 can be stably located directly above the port of the starter airway 26 away from the airflow sensor 23, so that the projection of the extension 41 on the plane where the port of the starter airway 26 away from the airflow sensor 23 is located can always completely cover the port of the starter airway 26. The material of the extension 41 can be one or more of silicone, rubber, and plastic; when the extension 41 and the side wall of the groove 31 are integrally formed, the material of the extension 41 is the same as that of the groove 31.

[0053] In a specific implementation, the bottom wall of the groove 31 can be a plane or an inclined plane. In this embodiment, the bottom wall of the groove 31 is a plane, and the plane is perpendicular to the length direction of the housing 21.

[0054] See also Figure 5a ,yes Figure 4 A schematic structural diagram of another embodiment of the groove of the connecting portion is provided.

[0055] In another embodiment, the bottom wall of the groove 31 is an inclined plane, and the angle formed by the inclined plane and the length direction of the housing 21 is greater than 30 degrees. The port of the start air passage 26 away from the air flow sensor 23 is arranged near the side wall of the groove 31 and is higher than the bottom wall of the groove 31; the location of the protrusion 34 is the highest point of the inclined plane, and the leaked liquid is preferentially gathered in the low-lying part of the inclined plane, which avoids the leaked liquid from contacting the port of the start air passage 26 away from the air flow sensor 23 to the greatest extent, thereby achieving maximum protection of the air flow sensor 23.

[0056] See also Figure 5b ,yes Figure 4 A schematic structural diagram of another embodiment of the groove of the connecting portion is provided.

[0057] In another embodiment, the bottom wall of the groove 31 is an inclined plane, and the angle formed by the inclined plane and the length direction of the housing 21 is greater than 30 degrees. A through hole 315 is formed on the bottom wall of the groove 31 to form a port of the start air passage 26 away from the air flow sensor 23; the through hole 315 is arranged close to the side wall of the groove 31. That is, the protrusion 34 does not need to be arranged on the bottom wall of the groove 31. The through hole 315 is located at the highest point of the inclined plane, and the leaked liquid is preferentially gathered in the low-lying part of the inclined plane, which avoids the leaked liquid from contacting the port of the start air passage 26 away from the air flow sensor 23 to the greatest extent, thereby achieving maximum protection of the air flow sensor 23.

[0058] See also Figure 6 ,yes Figure 4 A schematic structural diagram of another embodiment of the shielding portion is provided.

[0059] In other embodiments, the shielding portion 40 is a sealing cover or a sealing plug; the material of the sealing cover or the sealing plug is one or more of rubber, silicone, and plastic. The sealing cover or the sealing plug can be prepared separately to facilitate the formation of the third through hole 341 on the raised portion 34. The shielding portion 40 is arranged closely between the port of the third through hole 341 away from the bottom wall of the groove 31, that is, the port of the third through hole 341 away from the bottom wall of the groove 31 faces the atomizer assembly 1 and is sealed by the shielding portion 40, and an opening 342 is provided on the side wall of the raised portion 34 to communicate with the third through hole 341 to form a port of the starter airway 26 away from the airflow sensor 23. That is, the direction of the port of the starter airway 26 away from the airflow sensor 23 is perpendicular to the length direction of the housing 21, which can prevent the leakage from vertically entering the port of the starter airway 26 away from the airflow sensor 23, and prevent the leakage from damaging the airflow sensor 23.

[0060] See also Figure 7 , is a partial schematic diagram of the connection portion of the second embodiment of the power supply assembly provided by the present invention.

[0061] In the second embodiment, the structure of the power supply assembly 2 is substantially the same as that of the first embodiment, except that the protrusion 34 and the shielding portion 40 in the connecting portion 30 are arranged in a different manner.

[0062] In the second embodiment, the first bump 311, the second bump 312, the third bump 313, the fourth bump 314 and the protrusion 34 are arranged side by side, and the protrusion 34 is arranged between the third bump 313 and the fourth bump 314. It can be understood that the protrusion 34 only needs to be arranged close to the third bump 313 or the fourth bump 314, and does not need to be arranged between the third bump 313 and the fourth bump 314. The third through hole 341 disposed on the raised portion 34 is close to the port of the atomizer assembly 1 and is lower than the side wall of the third protrusion 313 or the fourth protrusion 314. The shielding portion 40 is an extension portion 41 of the side wall of the third protrusion 313 or the fourth protrusion 314. The extension portion 41 is the side wall of the third protrusion 313 or the fourth protrusion 314 extending to the top of the port of the starter airway 26 away from the airflow sensor 23 and covers the port of the starter airway 26 away from the airflow sensor 23; that is, the raised portion 34 is close to the third protrusion 313 or the fourth protrusion of the electrode contact 50. 314 is provided and the port of the third through hole 341 close to the atomizer assembly 1 is lower than the third protrusion 313 or the fourth protrusion 314 of the electrode contact member 50, and a shielding portion 40 is provided on the side wall of the third protrusion 313 or the fourth protrusion 314, and the shielding portion 40 is an extension portion 41 of the side wall of the third protrusion 313 or the fourth protrusion 314, and the extension portion 41 extends from the side wall of the third protrusion 313 or the fourth protrusion 314 to the top of the port of the start-up airway 26 away from the airflow sensor 23 and covers the port of the start-up airway 26 away from the airflow sensor 23. In other words, the projection of the extension portion 41 on the plane where the port of the start-up airway 26 away from the airflow sensor 23 is located completely covers the port of the start-up airway 26 away from the airflow sensor 23. Among them, the extension portion 41 and the third protrusion 313 or the fourth protrusion 314 can be integrally formed, or can be fixed together by other means such as adhesive.

[0063] In this embodiment, the bottom wall of the groove 31 is a plane and is perpendicular to the length direction of the housing 21. There is a gap between the extension portion 41 and the port of the start air passage 26 away from the air flow sensor 23.

[0064] See also Figure 8 ,yes Figure 7 A schematic structural diagram of another embodiment of a shielding portion is provided.

[0065] In other embodiments, the shielding portion 40 is a sealing cover or a sealing plug. The shielding portion 40 is closely arranged with the port of the third through hole 341 away from the bottom wall of the groove 31, and the port of the third through hole 341 away from the bottom wall of the groove 31 is sealed by the shielding portion 40. An opening 342 is arranged on the side wall of the third through hole 341 of the protrusion 34 to communicate with the third through hole 341, so as to form a port of the start air passage 26 away from the air flow sensor 23. The direction of the port of the start air passage 26 away from the air flow sensor 23 is perpendicular to the length direction of the housing 21, so as to prevent liquid leakage from vertically entering the port of the start air passage 26 away from the air flow sensor 23, thereby preventing liquid leakage from damaging the air flow sensor 23.

[0066] See also Fig. 9 ,yes Figure 7 A schematic structural diagram of another embodiment of a groove of a connecting portion is provided.

[0067] In another embodiment, the bottom wall of the groove 31 is composed of two inclined planes, and the angle formed by the inclined plane and the length direction of the housing 21 is greater than 30 degrees. The projection of the port of the start air passage 26 away from the air flow sensor 23 on the bottom wall of the groove 31 is the highest point of the bottom wall of the groove 31, which can avoid leakage from contacting the port of the start air passage 26 away from the air flow sensor 23 to the greatest extent, thereby protecting the air flow sensor 23 to the greatest extent.

[0068] The power supply assembly of the present invention comprises a housing, a bracket, an airflow sensor and a starting airway. The housing has a receiving portion for receiving at least part of the atomizing assembly; the bracket is arranged in the housing; the airflow sensor is arranged on the bracket; the starting airway is connected to the airflow sensor, and a port of the starting airway away from the airflow sensor is arranged on the bracket; by arranging a shielding portion between the port of the starting airway away from the airflow sensor and the atomizing assembly, it is possible to prevent liquid leakage of the atomizing assembly from directly entering the port of the starting airway away from the airflow sensor, thereby preventing liquid leakage from blocking the starting airway, reducing the influence of liquid leakage on the use of the airflow sensor, and avoiding the influence of liquid leakage on the start of the electronic atomizing device to the greatest extent.
