According to the invention, the locking mechanism 3 is arranged on the power supply device 1, and a user controls the locking mechanism 3 to lock or lock the atomizing device 2 through the sliding key 32, so that the assembling reliability of the atomizing device 2 is ensured, and the operation is convenient.

In this embodiment, the power supply device 1 includes a main body divided into two parts, namely a battery compartment and the accommodating groove 11. The battery compartment is used for accommodating batteries, a control panel, a switch, wires and other power supply and control components. Preferably, the battery compartment and the accommodating groove 11 are sealed and isolated from each other, that is, the liquid or dust in the accommodating groove 11 cannot extend into the battery compartment. The holding tank 11 one end opening, atomizing device 2 follow the opening is packed into in the holding tank 11 to be connected with the components and parts electricity in the battery compartment, in order to obtain the power.

As shown in fig. 2 and 3, the mount 31 includes a bracket 312 and a housing 311, and the bracket 312 is erected on the main body of the power supply device 1. In practical applications, a positioning hole may be disposed on the bracket 312, and a positioning post may be disposed on the main body to position the bracket 312; the bracket 312 may also be positioned in a placement groove formed in the main body and adapted to the bracket 312, so as to initially limit the bracket 312, thereby facilitating subsequent installation of the housing 311. The bracket 312 is provided with a mounting hole 3121 for mounting the limiting member 33 and the elastic member 34. The mounting hole 3121 is a through hole penetrating through the bracket 312, and one end of the through hole faces the receiving groove 11, and the other end faces the key 32. A rotating shaft 3122 is horizontally erected in the installation hole 3121, and the rotating shaft 3122 is perpendicular to the axial direction of the installation hole 3121. Two ends of the rotating shaft 3122 are respectively inserted into two opposite hole walls of the mounting hole 3121 and fixedly connected with the corresponding hole walls. In practical application, the rotating shaft 3122 can be inserted into the hole wall in an interference manner, and can also be fixedly connected in a threaded connection manner. The housing 311 covers the bracket 312, and forms an accommodating space for installing the limiting member 33, the elastic member 34 and the key 32 with the bracket 312. At the same time, the bracket 312 is fixedly connected with the main body to fasten the bracket 312 also to the power supply device 1. Thus, the bracket 312 does not need to be fixed independently, and the installation station is saved.

In this embodiment, as shown in fig. 2 and 4, the key 32 includes a key body 321, and a sliding groove 3123 adapted to the key body 321 is disposed on a side of the bracket 312 facing away from the accommodating groove 11. The button body 321 is accommodated in the sliding groove 3123 and can slide along the extending direction of the sliding groove 3123. One side of the key body 321, which is away from the bracket 312, is convexly provided with a force application part 322, and the shell 311 is provided with a runway-shaped limiting hole 3111 which is matched with the force application part 322. The force application portion 322 is exposed through the limiting hole 3111 for operation by a user. When the user slides the force application portion 322, the force application portion 322 slides in the limiting hole 3111 and drives the button body 321 to slide along the sliding groove 3123.

In this embodiment, as shown in fig. 6, the elastic element 34 and the limiting element 33 are both sleeved on the rotating shaft 3122. Referring to fig. 5, the position-limiting member 33 includes a position-limiting member body 331, the position-limiting member body 331 is provided with a first through hole 3311, and the rotating shaft 3122 is sleeved with the first through hole 3311. And the aperture of the first through hole 3311 is larger than the outer diameter of the rotation shaft 3122, so that the stopper body 331 can rotate around the rotation shaft 3122. The stopper body 331 has an abutting portion 332 protruding from one end thereof, i.e. a first end 334 of the stopper 33 is formed; the other end of the limiting member body 331 is provided with a latching portion 333, i.e. a second end 335 of the limiting member 33 is formed.

Referring to fig. 4-5 and fig. 7-8, the abutting portion 332 abuts against the key 32. Correspondingly, a guide groove 323 adapted to the abutting portion 332 is disposed on a side of the key body 321 facing the limiting member 33, i.e., a side facing away from the force applying portion 322, and the abutting portion 332 is at least partially received in the guide groove 323. The guide groove 323 includes an abutting surface 3231 abutting on the abutting portion 332, a transition surface 3232 connected to the abutting surface 3231 and parallel to the sliding direction of the key 32, and a guide surface 3233 connected to the transition surface 3232. An included angle between the guide surface 3233 and the transition surface 3232 and an included angle between the abutting surface 3231 and the transition surface 3232 are obtuse angles. The abutment surface 3231, the transition surface 3232 and the guide surface 3233 thus define a tapered guide groove 323 with an increasing opening. When the force application portion 322 slides along the limiting hole 3111 under an external force, the key body 321 is driven to slide along the sliding groove 3123, so that the guide groove 323 slides downward, the abutting portion 332 rotates under the action of the abutting surface 3231, and the limiting member body 331 and the latching portion 333 are driven to rotate around the rotating shaft 3122. When the external force on the force application portion 322 is removed, the limiting member 33 reversely rotates under the action of the elastic member 34, and drives the abutting portion 332 to rotate, and abuts against the abutting surface 3231 under the action of the guide surface 3233, so as to drive the key 32 to slide upward until the initial position is recovered. Furthermore, a limiting protrusion 3211 is protruded from a surface of the key body 321 contacting the contact surface 3231, and a depth of the guide groove 323 near one end of the contact surface 3231 is increased by the limiting protrusion 3211, so that the contact part 332 is prevented from sliding out of the guide groove 323.

The locking part 333 is engaged with the atomizing device 2. Correspondingly, the housing 311 is provided with a second through hole (not shown) corresponding to the latching portion 333, and the second through hole communicates with the receiving groove 11 and the mounting hole 3121. Meanwhile, the atomization device 2 is provided with a clamping groove 21 matched with the buckling part 333. Thus, the latching portion 333 can extend into the accommodating groove 11 through the second through hole and be locked into the locking groove 21. When the atomization device 2 is accommodated in the accommodating groove 11, the latching portion 333 is latched in the latching groove 21 to lock the atomization device 2.

Further, as shown in fig. 7 to 8, since the latching portion 333 and the abutting portion 332 are respectively adjacent to two opposite ends of the mounting hole 3121, an included angle between the latching portion 333 and the abutting portion 332 is greater than 90 degrees and less than or equal to 180 degrees. The angle between the latching portion 333 and the abutting portion 332 is an angle between a line connecting the latching portion 333 to the center of the first through hole 3311 and a line connecting the abutting portion 332 to the center of the first through hole 3311. In this way, an included angle formed by the connection line between the positioning portion 333 and the abutting portion 332 and the rotation center is an obtuse angle, so that the positioning portion 333 can be conveniently stretched under the condition of small-angle rotation, and the operation difficulty and the resetting difficulty are reduced.

In the present embodiment, as shown in fig. 2 and 6, the elastic member 34 is a torsion spring. The torsion spring includes a rotating coil 341, and the rotating coil 341 is formed by spirally winding a spring wire, which is stretchable in an axial direction. The rotating coil 341 is sleeved on the rotating shaft 3122 and can rotate around the rotating shaft 3122. One end of the rotating coil 341 leads out a first force arm 342, and the other end leads out a second force arm 343. The first force arm 342 is fastened to the mounting seat 31, and correspondingly, the bracket 312 is provided with a slot 3124 along the length direction thereof, the slot 3124 being adapted to the first force arm 342, when the housing 311 covers the bracket 312, the slot 3124 and the inner wall of the housing 311 enclose a mounting groove with a closed periphery. The first force arm 342 is inserted into the mounting slot to effect securement. The second arm 343 is in elastic abutment with a side of the second end 335 facing away from the receiving slot 11. When the second end 335 rotates around the rotation shaft 3122 under the driving of the first end 334, the second end 335 drives the second arm 343 to rotate. Since the first force arm 342 is fixed, the rotating coil 341 rotates around the rotating shaft 3122 by the second force arm 343 and is compressed in the axial direction.

Further, the torsion spring is a double torsion spring, which includes two rotating coils 341. The two rotating coils 341 are respectively located at two sides of the limiting member body 331. One first force arm 342 led out from one rotating coil 341 is fastened in the mounting groove at one end of the mounting seat 31, and the other first force arm 342 led out from the other rotating coil 341 is fastened in the mounting groove at the other end of the mounting seat 31. The second force arms 343 led out from the two rotating coils 341 are connected and elastically abutted against the second ends 335. Correspondingly, the second end 335 is concavely provided with a limit groove 3331, and the second force arms 343 of the two coils are accommodated in the limit groove 3331. Preferably, the limiting groove is of an arc-shaped structure, and the opening of the limiting groove and the surface of the second end 335 are in smooth transition, so that the second force arm 343 can slide into the limiting groove 3331 in the rotation process to realize limiting, and the second force arm 343 is prevented from sliding to the limiting part body 331, so that the thrust acting on the second force arm 343 is invalid, and further the torsion spring cannot be elastically deformed. In this embodiment, the two torsion springs are used to apply an elastic force to the positioning portion 333 from two ends of the limiting member 33, so that the stress on the limiting member 33 is uniform, the elastic force is increased, and the uneven stress or rebound failure of the limiting member 33 caused by a single torsion spring is avoided.

Referring to fig. 7 and 8, when the exposed portion of the force applying portion 322 is subjected to a force, the force applying portion 322 slides along the length direction of the limiting hole 3111 and drives the key body 321 to slide downward along the sliding slot 3123, so that the guide slot 323 moves downward and applies a pressure to the abutting portion 332; the abutting part 332 rotates clockwise around the rotating shaft 3122 and drives the latching part 333 to rotate clockwise, so that the latching part 333 is disengaged from the slot 21, the atomizing device 2 is unlocked, and the atomizing device 2 can be taken out at this time; meanwhile, the latching portion 333 drives the second force arm 343 of the torsion spring to rotate, so that the rotating coil 341 is compressed. When the external force on the force exerting portion 322 is removed, the force applied by the latching portion 333 to the second force arm 343 is removed, so that the rotating coil 341 recovers elastic deformation and drives the second force arm 343 to rotate counterclockwise, and the second force arm 343 in turn drives the latching portion 333 to rotate counterclockwise and to extend into the accommodating groove 11 again, and is clamped into the clamping groove 21, so as to lock the atomizing device 2; meanwhile, the latching portion 333 drives the abutting portion 332 to rotate counterclockwise, so that the guide groove 323 moves upward under the action of the abutting portion 332 and drives the key body 321 to move upward along the sliding groove 3123, and finally the force portion 322 moves upward along the length direction of the limiting hole 3111 and returns to the initial position. This embodiment adopts elasticity locking mechanism 3 to carry on spacingly to atomizing device 2, prevents that atomizing device 2 from deviating from in accommodating groove 11, perhaps is taken out by the mistake, and causes the outage. Meanwhile, the locking mechanism 3 automatically rebounds after being operated, so that the operation of a user is facilitated.
