With further reference to fig. 4 and 5, a first electrode 31 and a second electrode 32 are disposed at the bottom end of the second housing 20 of the atomizing device 100. In use, the first electrode 31 is electrically connected to one end of the heating element 50 and the second electrode 32 is connected to the other end of the heating element 50 for use in powering the heating element 50 after being used in conjunction with the power supply device 200.

In the preferred embodiment shown in fig. 4, the first electrode 31 has a cylindrical shape, and the second electrode 32 has an annular shape surrounding the first electrode 32; of course, an annular insulating silicone ring 33 is disposed between the first electrode 31 and the second electrode 32 to insulate the first electrode 31 from the second electrode 32.

Further as shown in fig. 4 and 5, the first electrode 31 and the second electrode 32 are respectively arranged on the upper side and the lower side of the housing of the atomizing device together with the suction nozzle 30, and the electrodes are coaxially opposite to the suction nozzle 30 in the length direction; while the first electrode 31 and the second electrode 32 are at least partly protruding at the bottom end of the housing of the atomizing device.

Meanwhile, a groove 321 circumferentially surrounding the second electrode 32 is provided on an outer side wall of the second electrode 32 for connection and retention with the power supply device 200.

Specifically, the porous body 40 and the heating element 50 are supported by the first electrode 31 and the second electrode 32 and held or fixed in the atomization device 100. Meanwhile, the first electrode 31 and the second electrode 32 are removable or detachable from each other along the length direction; of course, in operation the user can act as a location for the force by means of the recess 321 of the second electrode 32. The atomizing assembly including the porous body 40 and the heating element 50 may be removed from the atomizing device 100 along with the removal or detachment of the first electrode 31 and the second electrode 32 during the removal process, thereby facilitating the removal and replacement.

As shown in fig. 3 and 4, the atomizer 100 further includes a locking slot 22 disposed at the bottom of the housing of the atomizer, and the locking slot 22 is used to form a fixed connection when the atomizer 100 is combined with the power supply device 200. Of course, according to the preferred embodiment shown in fig. 4, the number of the catching grooves 22 is two, and both sides in the thickness direction of the atomizing device 100 are oppositely disposed.

With respect to the structure of the power supply device 200, see fig. 6 and 7; comprises the following steps:

in order to facilitate the receiving operation of the atomization device 100 in the receiving chamber 230, a guide wall 231 is disposed in the receiving chamber 230 and is inclined along the length direction, and the side wall 14 of the atomization device 100 is also inclined to match with the guide wall 231, so that when the atomization device 100 is received in the receiving chamber 230 along the length direction, the operation guide can be provided in cooperation with each other.

The bracket 262, which is made of rigid plastic material in practice, extends along the cross-sectional direction of the power supply housing, so as to divide the internal space of the power supply housing into two parts, i.e., the receiving cavity 230 located above and the installation space located below for installing the battery cell 261 for supplying power.

The first conductive elastic pin 263 and the second conductive elastic pin 264 penetrate through the bracket 262 from the lower part of the bracket 262 to the receiving cavity 230; for conducting an electrical current between the core 261 and the electrodes (i.e., the first electrode 31 and the second electrode 32) of the atomizing device 100. In particular, the method comprises the steps of,

the number of the first conductive pogo pins 263 is one, and is substantially located at the central axis of the receiving cavity 230;

the second conductive pogo pins 264 are two in number, and are disposed on both sides of the first conductive pogo pins 264 in the thickness direction of the power supply device 200 in a straight line.

In use, the first conductive pogo pin 263 abuts against the first electrode 31 of the atomizer 100 to form electrical conduction, and the second conductive pogo pin 264 abuts against the second electrode 32 of the atomizer to form electrical conduction. And the number of the second conductive pogo pins 264 is two, the stability of abutting or contacting with the second electrode 32 can be maintained.

As further shown in fig. 9, to facilitate the above conductive contact and to be more stable, the holder 262 is provided with a substantially circular recess 2621, and the first electrode 31 and the second electrode 32 of the atomizer device 100 are inserted into the recess 2621 when combined.

Of course, the first conductive pogo pin 263 and the second conductive pogo pin 264 penetrate into the cavity 2621, so that when the first electrode 31 and the second electrode 32 of the atomizer 100 extend into the cavity 2621, electrical conduction is formed.

As further shown in fig. 7 to 9, in order to stably maintain the connection with the power supply device 200 and form a lock when the atomization device 100 is received in the receiving chamber 230; a holding member 270 is also provided in the power supply device 200; the holding member 270 is driven to move in the width direction by the operation button 240 located at one side portion in the width direction of the power supply device 200. Wherein locking may mean that the aerosolization apparatus 100 is fixed or restrained, at least not freely movable and thus not removable from within the receiving chamber 230, when received in the receiving chamber 230.

The overall shape of the particular retaining element 270 is generally a C-shape that at least partially circumferentially surrounds the brace 262. The retaining member 270 is at least partially supported by the bracket 262 upon installation and is thus installed within the power supply apparatus 200. Meanwhile, the bracket 262 is further provided with a guide structure for providing a guide during the movement of the holding member 270 so that it can be stably moved in the width direction relative to the bracket 262 under the guide.

Meanwhile, the holding element 270 is provided with a catch 271 for cooperating with the catch 22 of the atomizing device 100 to form a snap connection when the atomizing device 100 is received in the receiving chamber 230, as shown in fig. 8. Of course, in the preferred embodiment shown in fig. 7-9, at least a portion of the surface of the top of the catch 271 is a sloped surface to provide a sloped guide for the opening of the catch 22 when the atomization device 100 is combined lengthwise.

When the atomization device 100 and the power supply device 200 need to be disengaged, the operation button 240 is pressed to drive the holding element 270 to move leftward in the width direction indicated by the arrow R3 in fig. 8, and the atomization device 100 can be removed in the length direction after the buckle 271 is disengaged from the card slot 22. In other alternative implementations, as the operating means for driving the holding member 270 to move and thus unlock the atomization device 100, other operating members actuated by sliding, rotating, or the like may be used instead of the above operating button 240.

In a more preferred embodiment, after the latch 271 is disengaged from the slot 22, a device for providing a pushing force to the atomizer 100 is disposed in the power supply device 200 to assist the atomizer 100 to move out in the length direction. In this embodiment, the pushing force is preferably provided by the elastic force of the first conductive pogo pin 263 and the second conductive pogo pin 264; specifically, when the atomizer 100 is engaged with the power supply device 200 to form electrical conduction, the first conductive pogo pin 263 and the second conductive pogo pin 264 are at least partially compressed, and when the latch 271 is disengaged from the slot 22, the elastic restoring force of the first conductive pogo pin 263 and the second conductive pogo pin 264 acts as an outward pushing force to push the atomizer 100 for a certain stroke displacement so that at least a portion of the atomizer is ejected out of the receiving cavity 230, thereby facilitating the removal operation by the user. Or other variations, a spring or like element may be used alone to provide a similar pushing force to facilitate the removal operation.

Alternatively, in other variant implementations, the first conductive latch 263 and the second conductive latch 264 may be replaced by elastic electric contacts or elastic electric terminals, which are used as electrodes for outputting electric energy from the power supply device 200 and promote the removal of the atomization device 100 from the receiving cavity 230 by elastically forming a pushing force.

Referring to the preferred embodiment shown in fig. 9, to provide stability in mounting the retaining member 270 within the power supply apparatus 200, a biasing member is provided within the power supply apparatus 200, which in fig. 9 is a linear spring 280 extending in the width direction, the linear spring 280 having one end abutting against the bracket 262 and the other end abutting against the retaining member 270. The linear spring 280 provides damping in the movement of the holding element 270 on the one hand; on the other hand, when the latch 271 is engaged with the slot 22, the elastic force opposite to the arrow R3 in fig. 8 is provided to make the latch 271 have a tendency of moving rightward, so as to prevent it from moving leftward in the direction of the arrow R3 to release the engagement. Alternatively, in other embodiments, the biasing function of the biasing element may be provided by a device having an elastic return function, such as a magnet, a torsion spring, or a silicon rubber.

As further shown in fig. 9, the guide structure of the holder 262 to the holding element 270 is embodied with a plurality of portions. For example, in fig. 9 the holder 262 has a partially convex guide surface 2623, against which the holding element 270 is moved on the one hand, and which guide surface 2623, after assembly, projects into a recess on both sides of the holding element 270 in the thickness direction. For another example, a notch 2622 is provided in the wall of holder 262 defining cavity 2621, and retaining element 270 is provided with a protrusion 272 extending toward notch 2622; in practice, the protrusion 272 extends at least partially into the notch 2622 to prevent deflection in other directions during movement of the retaining element 270, and also at least partially provides guidance.

Of course, in order to facilitate the installation of the linear spring 280, the holding member 270 is provided with a receiving hole 273 therein, and the linear spring 280 is received and held in the receiving hole 273.

Meanwhile, the operation button 240 is provided with a coupling structure, such as a snap projection 241 shown in fig. 9, to which the holding member 270 is fixedly coupled.

Or in yet another alternative implementation, may be locked or unlocked using a circumferentially extending groove 321 provided on the outside wall of the second electrode 32. In particular, the method comprises the steps of,

the length of the protrusion 272 of the holding member 270 may be longer, and thus when the atomization device 100 is received in the receiving chamber 230, the protrusion 272 may extend into the groove 321, and the atomization device 100 may be prevented from moving in the length direction to achieve fixation; when the user needs to remove the container, the linear spring 280 is driven or operated by the operating button 24, the holding element 270 is driven to move outwards by the elastic force of the linear spring 280, and the protrusion 272 is disengaged from the groove 321, so that the locking of the atomization device 100 is released.

The holding element 270 in the power supply device 200 is driven to move by the operation button 240, so that the operation can be performed between the engagement and disengagement of the atomization device 100 and the power supply device 200, and the atomization device 100 and the power supply device 200 can be stably combined and conveniently used, and the atomization device 100 and the power supply device 200 can be conveniently removed.

In a variation of the above preferred embodiment, the holding member 270 may also be provided on the atomizing device 100, and the operation member corresponding to the operation button 240 and the like is also formed on the atomizing device 100; at least a portion of the operation member such as the operation button 240 is exposed to the outside for operation when the atomizer 100 is received in the receiving chamber 230. Meanwhile, a structure of fitting locking of the fitting holding member 270 is provided in the power supply device 200, and fitting forms locking.

Further during the suction process, as shown in fig. 7 to 10, the airflow path of the power supply device 200 is configured to include:

the main housing 210 is provided with a second through hole 224, and the second through hole 224 is used as a second air inlet 224 for allowing external air to enter the power supply device 200; of course, the second air inlet 224 is in air flow communication with the first air inlet 21 when the atomizing device 100 is received within the power supply device 200.

The second air inlet 224, in the preferred embodiment shown in fig. 7, is arranged in an elongated shape extending along the length of the power supply housing, generally in the shape of a kidney.

Of course, in a preferred embodiment, the second air inlet 224 and the first air inlet 21 are substantially aligned when the atomizing device 100 is received in the power supply device 200.

An air flow regulating member 250, the air flow regulating member 250 being movable along a length direction of the power supply device 200, and further being movable between a position of fully opening the second through-hole 224 (for example, a state shown in fig. 8) and a position of fully closing the second through-hole 224 (for example, a state shown in fig. 3); and the portion of the airflow adjusting member 250 other than the overlap with the second through-hole 224 during the movement forms the above second air inlet 224, and the size of the formed second air inlet 224 is varied by the difference in the degree or area of the overlap with the second through-hole 224 during the movement to adjust or change the amount of airflow or the airflow rate during the suction.
