That is, the main body 1 includes an insertion groove 12 and an accommodation chamber, and the insertion groove 12 and the accommodation chamber communicate with each other through a communication structure 11. An insertion groove 12 is provided at one end of the body 1 for insertion of a load.

The magnetic mechanism 3 is of an annular structure, and the magnetic mechanism 3 is clamped inside the communicating structure 11. The area enclosed by the inner wall of the magnetic mechanism 3 is the inner ring space, one end of the conductive mechanism 2 passes through the inner ring space of the magnetic mechanism 3 and is exposed to the insertion groove 12 so as to be contacted with a load extending into the insertion groove 12, and the other end of the conductive mechanism 2 is exposed to the accommodating cavity so as to be connected with the electronic device 4. The magnetic mechanism 3 may include a magnet, and the magnet may be a permanent magnet, an electromagnet, or the like, which is capable of adsorbing a ferromagnetic substance. In the present embodiment, the magnetic mechanism 3 is exemplified by a permanent magnet.

When the power supply device is applied to the electronic atomizing apparatus, as shown in fig. 8 to 13, the load is the atomizing device 6, and the power supply device is used to supply power to the atomizing device 6. The electronic device 4 is for providing electrical energy, the electronic device 4 comprising a power source. The power source may be a replaceable power source or a rechargeable power source. When the power is the replaceable power, the accommodating cavity is provided with an opening, the opening is covered by a cover body, and the cover body is detachably connected with the main body 1, for example, in a clamping connection mode. After the cover body is opened to leak out of the opening, the power supply can be taken out of or put in the accommodating cavity so as to replace the power supply. When the power supply is a rechargeable power supply, the power supply is provided with a charging port, the main body 1 is provided with a charging port, and the charging port is exposed at the charging port and used for connecting a charging external cable with the charging port so as to charge the power supply.

As shown in fig. 5 to 7, in an alternative embodiment of the present embodiment, the main body 1 includes a housing 13 and a bracket 14, the communicating structure 11 and the accommodating chamber are disposed in the bracket 14, and the conductive mechanism 2, the electronic device 4 and the magnetic mechanism 3 are mounted in the bracket 14. The housing 13 includes a chamber with an opening at one end, the bracket 14 mounted with the conductive mechanism 2, the electronic device 4 and the magnetic mechanism 3 is extended into the chamber from the opening of the housing 13, and after the bracket 14 is fixed with the housing 13, the insertion groove 12 is formed between the end surface of the bracket 14 facing the opening side of the housing 13 and the inner side wall of the housing 13.

In an alternative embodiment, the communicating structure 11 may be a through hole, with a cylindrical communicating portion.

Alternatively, in a preferred embodiment, the communicating structure 11 is a counter bore, and includes a large-diameter bore section and a small-diameter bore section which are communicated with each other, and a step surface is formed between the large-diameter bore section and the small-diameter bore section. The large diameter hole section is located at a side close to the insertion groove 12, and the small diameter hole section is located at a side close to the accommodation chamber.

As shown in fig. 7 and 4, optionally, the conductive mechanism 2 is provided with a limiting structure 21, the conductive mechanism 2 abuts against the step surface of the counter bore through the limiting structure 21, and the magnetic mechanism 3 is clamped in the counter bore and presses the limiting structure 21 against the step surface. Specifically, the magnetic mechanism 3 is clamped in the large-diameter hole section of the counterbore, the limiting structure 21 is located in the large-diameter hole section, and one side end face of the limiting structure 21 is abutted to the step face.

In one possible design, the limiting structure 21 is a limiting edge convexly formed on the side wall of the conductive mechanism 2, the surface of one side of the limiting edge is abutted against the step surface, and the peripheral surface of the limiting edge is in interference fit with the inner hole wall of the counter bore so as to be pre-fixed in the counter bore. Because the peripheral surface of spacing reason and the interior pore wall interference fit of counter bore (the major diameter hole section of counter bore), consequently, in the in-process of assembling, insert conductive mechanism 2 earlier the counter bore, conductive mechanism 2 is through spacing reason and the interior pore wall prepositioning of counter bore to follow-up installation magnetic mechanism 3, magnetic mechanism 3 stretches into the counter bore after, presses spacing reason against the step face at the counter bore, thereby further fixed conductive mechanism 2.

In this arrangement, a stopper edge is provided on the side wall of the conductive mechanism 2 so as to project in the direction away from the axis, and the stopper edge is used as the stopper structure 21. In a possible embodiment, the limiting edge is of a ring-mounted structure, or in another possible embodiment, the limiting edge is composed of a plurality of limiting blocks, the limiting blocks are arranged at intervals along the circumferential direction of the conducting mechanism 2, and the limiting blocks are all located in a plane perpendicular to the axis of the conducting mechanism 2.

In one possible design, as shown in fig. 4 and 13, the main body 1 is further provided with a reinforcing rib 15, and the reinforcing rib 15 is located at the edge of the opening of the counter bore on the side away from the limiting edge. The reinforcing rib 15 is used for improving the limiting and supporting force of the conductive mechanism 2. The reinforcing rib 15 is located on the side of the part of the structure where the conductive means 2 protrudes below the counter bore, so that deflection of the conductive means 2 can be reduced or avoided to some extent.

In an alternative embodiment, the reinforcing rib 15 is a ring structure, and one end of the conductive mechanism 2 extends into an inner ring area of the ring structure after passing through the counter bore, and extends below the reinforcing rib 15 after passing through the inner ring area of the ring structure. In another alternative embodiment, the reinforcing ribs 15 are a plurality of spaced-apart bar structures that are spaced apart along the circumference of the conductive mechanism 2. Alternatively, during installation of the conductive mechanism 2, one end of the conductive mechanism 2 extends through the gap between the plurality of bar structures to below the reinforcing rib 15.

In an alternative embodiment of this embodiment, the portion of the conductive means 2 passing through the magnetic means 3 is spaced from the inner circumferential surface of the magnetic means 3. Or, the part of the conductive mechanism 2 located in the inner ring area of the magnetic mechanism 3 is spaced from the inner ring surface of the magnetic mechanism 3, that is, a gap is formed between the side surface of the part of the conductive mechanism 2 located in the inner ring area of the magnetic mechanism 3 and the inner ring surface of the magnetic mechanism 3, and the gap facilitates the heat dissipation of the conductive mechanism 2, so as to improve the heat dissipation effect of the conductive mechanism 2.

In one possible design, as shown in fig. 4 to 7, the conductive mechanism 2 includes a fixed portion 22, a movable portion 23, and an elastic portion, the fixed portion 22 is connected to the movable portion 23 through the elastic portion, the limiting structure 21 is disposed on the fixed portion 22, the movable portion 23 is exposed from the insertion slot 12, and the movable portion 23 can move toward the fixed portion 22 under an external force. That is, under the elastic force of the elastic portion, the fixing portion 22 has one end located in the inner annular space of the magnetic mechanism 3 and the other end extending into the accommodating chamber without receiving an external force, and the moving portion 23 has one end located in the inner annular space of the magnetic mechanism 3 and the other end extending into the insertion groove 12. After the load is inserted into the insertion groove 12, the load pushes the movable portion 23 toward the fixed portion 22 (i.e., toward the accommodating chamber), and the elastic portion compresses and stores the force. In this arrangement, the load and the moving portion 23 are brought into contact with each other by the elastic portion. When the load is separated from the main body 1, the moving portion 23 is protruded into the insertion groove 12 by the elasticity of the elastic portion to restore the original position.

One end of the moving part 23 is elastically connected to the fixing part 22 through an elastic part, and the other end of the moving part 23, i.e. the end far away from the fixing part 22, is a free end which can move between a first position and a second position. Specifically, when the moving part 23 moves to the limit position in a direction approaching the fixed part 22 (or in a direction approaching the accommodating chamber), the free end of the moving part 23 is located at the first position. When the moving part 23 moves to the limit position in a direction away from the fixed part 22 (or in a direction away from the accommodating chamber), the free end of the moving part 23 is located at the second position. That is, the conductive mechanism 2 is a telescopic structure, and when the conductive mechanism 2 is in a fully contracted state, the free end of the moving part 23 is located at a first position, and when the conductive mechanism 2 is in a fully extended state, the free end of the moving part 23 is located at a second position.

Further, there is a third position between the first position and the second position, and when the conductive mechanism 2 is in a natural state when not being subjected to an external force, the free end of the moving portion 23 is located at the third position.

The second position and the third position are both located in the insertion slot 12, i.e. when the conductive means 2 is not pressed, the free end of the moving part 23 extends into the insertion slot 12. After the load is inserted into the insertion slot 12, the free end is mounted in place after the load pushes the free end to move for a certain distance, so that the free end is abutted against the load after the load is mounted, and the stability of electrical connection between the free end and the load is improved.

The first position is located outside the insertion groove 12, in particular in the communicating structure 11, or, preferably, in the inner annular space of the magnetic means 3. This arrangement allows the free end of the moving part 23 to fully extend into the inner annular space of the magnetic means 3 within the limits of the self-compression of the elastic part and the moving part 23. This prevents the load from exerting excessive pressure on the free end and causing damage to the conductive means 2.

Further, in the first position, the end face of the free end of the moving portion 23 is spaced apart from the plane of the end face of the magnetic mechanism 3 in the direction toward the insertion slot 12. That is, even if a load is strongly inserted into the insertion slot 12, the load is restrained by the magnetic mechanism 3, that is, the load moves at most to contact with the end surface of the magnetic mechanism 3 on the side toward the insertion slot 12, and the end surface of the free end of the movable portion 23 pushed by the load moves to a position flush with the end surface of the magnetic mechanism 3 on the side toward the insertion slot 12, which is between the first position and the second position, and also between the first position and the third position, that is, the free end has not moved to the limit position (first position), the magnetic mechanism 3 prevents the load from further pressing the movable portion 23, that is, the magnetic mechanism 3 protects the conductive mechanism 2 and restrains the load.

In a possible design, the conductive mechanism 2 further includes a connecting portion 24, the connecting portion 24 is connected to the fixing portion 22, and the connecting portion 24 is used for electrically connecting with an external auxiliary wire. Specifically, the moving portion 23 is located on a side of the fixing portion 22 facing the insertion slot 12, and the connecting portion 24 is connected to a side of the fixing portion 22 facing the receiving cavity, into which the connecting portion 24 may protrude. The connection portion 24 may be a columnar conductive structure for connecting with an external auxiliary cable by soldering.

In the conductive mechanism 2, the connecting portion 24, the fixing portion 22, and the moving portion 23 are all made of a conductive material, such as metal.

In one possible design, the outer diameter of the connecting portion 24 is 0.3 to 0.5 times the outer diameter of the fixing portion 22. That is, the connecting portion 24 has an outer diameter smaller than that of the fixing portion 22, so that the connecting portion 24 and the external auxiliary wire can be fixed by welding during the assembling process, and then the connecting portion 24 and the external auxiliary wire can pass through the insertion groove 12 and the communicating structure 11 and extend into the accommodating cavity. In this way, on the one hand, since the outer diameter of the connecting portion 24 is relatively small, even if the actual outer diameter is increased due to the solder adhered to the outer circumference during welding, the connecting portion can easily pass through the insertion groove 12 and then pass through the communicating structure 11 to extend into the accommodating cavity. On the other hand, since the connecting portion 24 can be welded and fixed with the external auxiliary wire and then smoothly pass through the communicating structure 11, it is not necessary to complete the welding operation of the connecting portion 24 and the external auxiliary wire in the accommodating cavity, so that the connecting portion 24 can be far away from the main body 1 during the welding operation, and the main body 1 is prevented from being damaged by melting.

In an alternative embodiment, the conductive mechanism 2 may be modified using a conductive pogo pin or a conductive spring probe.
