The bottom of the second sliding portion 48b protrudes upward to form a wedge-shaped portion 90, a side of the wedge-shaped portion 90 facing the second concave surface 86a forms a second guide surface 90a, a space is formed between the second guide surface 90a and the second concave surface 86a, the second guide surface 90a is an inclined surface and extends downward in a direction toward the first sliding portion 48a, a second slide way 92 is formed between the second side surface 86b and a side wall of the first sliding portion 48a, a pad 93 protrudes from a side wall of the first sliding portion 48a facing the second side surface 86b, the pad 93 has an inclined surface parallel to the second side surface 86b, and therefore the width of the second slide way 92 is the same.

The operation of the locking device 13 will be explained with reference to fig. 9 to 16.

As shown in fig. 9 and 10, when the locker 13 is in the original state, the pressing plate 12a is located at the first distance from the upper case 14, and the fragrance emitting opening 44 is at the maximum. The first extension 52c and the second extension 52d of the positioning member 52 are respectively located above the first positioning block 84 and the second positioning block 86. When the pressing member 12 is pressed down for the first time, the housing 46 moves down to drive the sliding member 48 to move down through the spring 50, the hook 72 at the bottom of the sliding member 48 abuts against the bottom wall of the cylinder 14c and forces the rotating portion 48c to rotate counterclockwise, so that the opening 74 of the hook 72 is clamped with the buckling portion 38 and finally the buckling portion 38 is completely clamped into the opening 74. In the process, as shown in fig. 11 to 12, the first extending portion 52c of the positioning member 52 slides along the first guiding surface 84c, so that the positioning member 52 rotates relative to the housing 46 due to the arc-shaped first guiding surface 84 c. When the pressing member 12 is pressed to the lowermost position, the first extending portion 52c is disengaged from the first guide surface 84c and moved into the first concave surface 84a, and the second extending portion 52d is also positioned in the second concave surface 86 a. As shown in fig. 13-14, after the external pressing force is removed, the pressing member 12 tends to move back, i.e. move up, under the elastic force of the spring 50, but since the first extending portion 52c is caught in the first concave surface 84a and the second extending portion 52d is caught in the second concave surface 86a, the hook 72 keeps the engaging state with the engaging portion 38, so that the pressing member 12 keeps the current pressing position without moving up, and at this time, the locking device 13 is in the locking state, the pressing plate 12a is located at the second distance from the upper shell 14, and the fragrance dispensing opening 44 is at a minimum.

When it is desired to open the press-on member 12 again, the press-on member 12 is pressed down again so that the opening 74 of the hook 72 is disengaged from the engaging portion 38, thereby achieving restoration. As shown in fig. 15-16, in the process, the first extension 52c of the positioning member 52 is disengaged from the first concave surface 84a, and the second extension 52d is disengaged from the second concave surface 86 a. When the second extension 52d contacts the second guiding surface 90a, the positioning member 52 is forced to rotate relative to the housing 46 again due to the inclined surface of the second guiding surface 90a, so that the second extension 52d enters the second slide way 92 and the first extension 52c enters the first slide way 88. When the pressing force is removed, the slider 48 is returned to the original state by the elastic force of the spring 50, so that the opening 74 of the hook 72 is disengaged from the engaging portion 38, and the pressing member 12 is returned to the original state.

After installation, the cylinder 14c extends into the accommodating cavity 22, and the pressing plate 12a can be switched between the original state and the locking state by pressing the pressing plate 12a, so that the size of the fragrance emitting opening 44 is adjusted, and the fragrance emission amount is changed. The fragrance of the fragrance material flows from the fragrance-emitting opening 44 to the outside of the fragrance device 10 through the fragrance-emitting passage.

In the illustrated embodiment, when the pressing plate 12a is in the locked state, there is also a gap between the outer side wall of the pressing plate 12a and the inner side wall of the upper casing side wall 14b, when the fragrance dispensing opening 44 is at a minimum, but not completely closed. In other embodiments, when the pressing plate 12a is in the locked state, the outer sidewall of the pressing plate 12a abuts against the inner sidewall of the upper casing sidewall 14b to close the fragrance emitting opening 44.

In the illustrated embodiment, a protrusion 94 protrudes from the bottom center of the bottom shell 18 toward the receiving cavity 22, and the top of the protrusion 94 protrudes into the through hole 40 at a predetermined position. The protrusion 94 is used to position the upper shell 14 to prevent the upper shell 14 from shaking during use.
