The terminology used in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the present application. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1-2, an electronic atomizer 100 according to an embodiment of the present disclosure includes a battery assembly 10, an atomizer 20, and a cap 30. Electronic atomizer 100 is cylindrical in shape, and battery assembly 10 is used to power atomizer 20, and atomizer 20 is used to heat a liquid to produce an aerosol that can be inhaled by a user. The cap 30 is sleeved on the atomizer 20; the cap 30 abuts against the battery assembly 10, and the outer diameter of the cap 30 substantially coincides with the outer diameter of the battery assembly 10, so as to maintain the aesthetic appearance of the electronic atomizer 100. One end of the cap 30 is further provided with a hanging rope to facilitate carrying by a user.

The atomizer 20 includes a reservoir for storing a liquid from which an aerosol can be generated, a liquid delivery unit for delivering the liquid stored in the reservoir to a heating element, and a heating element (none of the figures shown) for heating the liquid delivered by the liquid delivery unit to generate the aerosol. After the aerosol is generated, the user may inhale through the mouth end of the atomizer 20.

As shown in fig. 3-11, the battery assembly 10 includes a housing 11, a battery 12, a bracket 13, a circuit board 14, an airflow sensor 15, a threaded sleeve 16, and a lamp housing 17.

As will be understood in conjunction with fig. 5 to 8, the housing 11 is hollow and tubular, and the lower end of the housing 11 has a step 111 and a step 112, the step 111 is located above the step 112, and both the step 111 and the step 112 are formed by partially protruding inner surfaces (along a radial direction).

The battery 12, the holder 13, the circuit board 14, the airflow sensor 15, and the screw boss 16 are assembled and inserted from an opening at the upper end of the housing 11, and after riveting, the upper end of the holder 13 abuts against the screw boss 16, the lower end of the holder 13 abuts against a face 141 of the circuit board 14, and the other face 142 of the circuit board 14 abuts against the step 111, so that the circuit board 14 is positioned substantially perpendicular to the longitudinal direction of the housing 11. The atomizer 20 may be used to check the function of the battery 12 prior to riveting.

The threaded sleeve 16 is fixed at one end in the housing 11 and at the other end has an internal thread, by means of which it is connected to the atomizer 20. The threaded sleeve 16 is provided with an inner tube and an outer tube, and the upper end and the lower end of the inner tube are both open; the upper end of the outer tube is closed, and the lower end of the outer tube is open. The gap between the inner and outer tubes forms an annular space. It should be noted that the connecting member between the battery pack 10 and the atomizer 20 is not limited to the case of the screw bushing in the drawings.

In this example, battery assembly 10 also includes an electrode connection for electrical connection with atomizer 20; the electrode connector includes an electrode ring 163, an insulating ring 164, and an elastic member 165. The electrode ring 163, the insulating ring 164 and the elastic element 165 are all fixedly arranged in the inner pipe of the threaded sleeve 16, and the insulating ring 164 is arranged between the electrode ring 163 and the inner pipe of the threaded sleeve 16; one end of the elastic member 165 abuts on the electrode ring 163, and the other end abuts on the insulating ring 164. The electrode ring 163 is movable up and down by the screw thread force of the elastic member 165 and the atomizer 20. The positive pole of the battery 12 is electrically connected to the electrode ring 163 and the negative pole of the battery 12 is electrically connected to the threaded sleeve 16.

In this example, the closed end of the outer tube of the threaded sleeve 16 has an air inlet 161, the upper end of the inner tube of the threaded sleeve 16 opens to form an air outlet 162, and when the electronic atomization device 100 is suctioned, the air flow flows in from the air inlet 161, passes through the annular space, the holder 13, and the electrode ring 163, and then flows out from the air outlet 162 to form an air flow path. The electrode ring 163 has axially extending through-holes along which the gas flow flows in or out.

As will be understood in conjunction with fig. 9-11, the bracket 13 is disposed within the housing 11. The holder 13 is substantially tubular, with one end open and the other closed. The open end of the holder 13 is received in the annular space, forming a chamber 131 between the open end and the closed end, and the side wall also has an opening through which the battery 12 can be received and held in the chamber 131; after the air flows in from the air inlet 161, the air also flows out from the air outlet 162 through the opening.

In this example, the bracket 13 has an abutting portion 1321, and an extending portion 1322 extending from the abutting portion 1321 toward the face 141 of the circuit board 14; the circuit board 14 has a through hole or slot 143 that extends through the faces 141 and 142; the extension 1322 is accommodated in the through hole 143, and the contact portion 1321 contacts the surface 141. The structure 132 including the abutting portion 1321 and the extending portion 1322 allows the lower end of the bracket 13 to abut against the surface 141 of the circuit board 14 after caulking, thereby fixing the circuit board 14 without fixing the circuit board by screws.

In this example, the bracket 13 also has a snap 133, the circuit board 14 has a through hole 144 passing through the faces 141 and 142; the latch 133 engages the through hole 144 to latch the circuit board 14 to the bracket 13. Specifically, the catch 133 includes an extension 1331 extending toward the face 141, and an abutment 1332 projecting from the extension 1331; after the extension 1331 passes through the through hole 144, the abutment 1332 may abut the face 142.

In this example, one end of the bracket 13 facing the surface 141 further has a receiving portion 134, and the airflow sensor 15 is electrically connected to the circuit board 14 and at least partially received in the receiving portion 134. The airflow sensor 15 is mounted in the receiving portion 134 substantially parallel to the circuit board 14, and the airflow sensor 15 is spaced apart from the circuit board 14.

As will be understood from fig. 12, the lampshade 17 has a locking member 171 extending toward the surface 142, and the locking member 171 is engaged with the step 112 to lock the lampshade 17 on the housing 11. In this example, the catch 171 is a radially extending projection.

As will be understood with reference to fig. 4, 8-10, and 12, the battery assembly 10 further includes a charging member 145 electrically connected to the circuit board 14 and a light guide member 146, and the lamp housing 17 has a through hole 172 receiving a portion of the charging member 145 and a through hole 173 receiving a portion of the light guide member 146. The receiving portion 134 also has an airflow hole 1341. When the electronic atomization device 100 is sucked, due to the existence of the airflow path extending from the air inlet 161 to the air outlet 162, a negative pressure is formed above the airflow through hole 1341 and can be transmitted to one side of the airflow sensor 15, the outside air can also be communicated with the other side of the airflow sensor 15 through the gap in the charging member 145 and the opening on the circuit board 14, and a sealing member is arranged between the side wall of the airflow sensor 15 and the inner surface of the accommodating portion 134, so that the upper side and the lower side of the airflow sensor 15 are hermetically isolated. When negative pressure is generated at one side of the airflow sensor 15, the airflow sensor 15 can sense the negative pressure difference generated at the two sides and feed back a sensing signal to the circuit board 14, thereby controlling the atomizer 20 to start heating.
