The above structure can be directly arranged on the outer side wall of the inner shell, or a groove body can be arranged on the outer side wall of the inner shell, and the above structure is arranged in the groove body, so as to avoid increasing the transverse width of the outer side wall of the inner shell, thereby avoiding increasing the size of the fragrance diffusing device in the transverse direction, and making the structure of the fragrance diffusing device more compact. Since the two side walls of the groove 15 on the first protrusion 13 are inclined, and the two side walls of the first top block 14 are also inclined, the two inclined side walls of the groove 15 and the two side walls of the first top block 14 cooperate to form the inclined first downward groove 103 and the inclined third upward groove 104. The tail section of the second strip-shaped protrusion 12 is in an L shape, and the vertical edge of the L-shaped tail section protrudes downward to form the first top block 14.

[0035] In the preferred embodiment, referring to Figures 3-4The elastic locking assembly further comprises an elastic stopper 16 and a second top block 17 extending from the second strip-shaped protrusion 12, the elastic stopper 16 extends to the second top block 17 and is in contact with the second top block 17, and the elastic member 8 moves from the second section of the descending groove 105 to the first section of the ascending groove 101 after the extended part of the elastic stopper 16 is opened by the second top block 17.

The elastic stopper 16 is made of plastic material and has elastic deformation characteristics. When the elastic member 8 moves along the second section of the descending groove 105, the extended part of the elastic stopper 16 is opened, the free end of the extended part of the elastic stopper 16 is away from the side wall on the upper side of the second top block 17, and the elastic member 8 can smoothly pass through and enter the first section of the ascending groove 101. The extended part of the elastic stopper 16 is arranged to further form the second section of the ascending groove 102 by the extended part of the elastic stopper 16, the elastic stopper 16, the first protrusion 13 and the first strip-shaped protrusion 11, and form the second section of the descending groove 105 by the extended part of the elastic stopper 16, the elastic stopper 16, the first protrusion 13 and the second strip-shaped protrusion 12. The simple and ingenious structure design realizes the locking and unlocking of the inner shell. In addition, the instantaneous blocking of the elastic member 8 by the extended part of the elastic stopper 16 can prevent the inner shell from moving out of the shell body 1 instantly, and improve the user's use feeling. In addition, the second protrusion 18 is arranged below the first protrusion 13, and the elastic stopper 16 is sleeved on the second protrusion 18, that is, the elastic stopper 16 is in mortise connection with the second protrusion 18, and the two do not rotate relative to each other.

[0036] In the preferred embodiment, the elastic member 8 is always in an elastic deformation state during the movement in the guide groove. Specifically, the shell body 1 further comprises a middle shell, and the elastic member 8 is connected to the middle shell. The middle shell can be an integral whole or formed by sleeving a first middle shell 191 and a second middle shell 192.

The middle shell can not only fix the elastic member 8 but also ensure that the bending section of the elastic member 8 is matched with the guide groove. When the bending section of the elastic member 8 is constrained in the guide groove, the elastic member 8 is in an elastic deformation state, which facilitates the lane change of the elastic member 8 in the guide groove. The material of the elastic member 8 is metal, which has a long service life.

[0037] In the preferred embodiment, referring to Figures 1-4 The elastic locking assembly has a plurality of elastic locking assemblies, which are arranged at intervals along the circumference of the inner housing, so that the movement of the inner housing is more stable, and the problem of jamming of the inner housing due to unstable movement is avoided.

The spring mounting groove has three spring mounting grooves arranged at intervals along the circumference of the lower housing 32. The spring 20 is arranged in the spring mounting groove, and the spring 20 extends partially out of the spring mounting groove. When the inner housing is in the locked state, the spring 20 is in a compressed state. When the user needs to lock the inner housing, the atomizer assembly is pressed, so that the inner housing is pressed and moves away from the opening at the top end of the shell body 1. At this time, the relative movement between the elastic member 8 and the inner housing occurs, that is, the elastic member 8 moves in the first movement track groove. When the elastic member 8 reaches the locking plane 9, the elastic restoring tendency of the spring 20 causes the bent section of the elastic member 8 to abut against the locking plane 9, thereby locking the inner housing. When the user needs to unlock the inner housing, the atomizer assembly is pressed again, so that the inner housing is pressed and the first top block 14 on the inner housing acts on the bent section of the elastic member 8, forcing the bent section of the elastic member 8 to move away from the locking plane 9 and enter the third upward groove 104 and change lanes to the second downward groove 105. At this time, the force acting on the spring 20 is released, and the spring 20 is pushed by the elastic restoring force to move along the direction towards the opening at the top end of the shell body 1, so that the atomizer assembly partially emerges out of the opening at the top end of the shell body 1. At this time, the user can pull out the atomizer assembly and the essential oil bottle 2 together to replace the essential oil bottle 2 or add essential oil to the essential oil bottle 2. The user can achieve the locking and unlocking of the inner housing by repeating the above actions. Through the above structure, the locking and unlocking of the inner housing can be achieved, which is simple in structure, hidden in the shell body 1, ingenious in design, compact in structure, and does not affect the appearance of the fragrance diffusing device.
