Slot (not shown), positioning card point and locating groove cooperation, it is fixed to turn to open or close position progress stuck point to cover board 20
Position.It should be understood that can also be in the end face of the first protrusion 131 in the first cylinder 13 (towards that side of the second cylinder 23
Surface) it is equipped with locating groove, and positioning is being correspondingly provided in the second protrusion 231 of the second cylinder 23 and the second recess portion 230
Stuck point, positioning card point and locating groove cooperation are equally able to achieve and turn to open or close position to cover board 20 to carry out stuck point fixed
The effect of position.It can depend on the circumstances for positioning card point and the locating groove specific location being arranged and the quantity of setting, as long as not
Positioning card point and locating groove are located in transition region, optimal embodiment is that two positioning card points of setting and two are fixed
Whether position card slot, can go to the prompt of position, user compares during rotation feel to user one.
As shown in Fig. 2, Fig. 3, Fig. 6 and Fig. 7, when assembling, the first cylinder 13 is shaped in bottom plate 12, the second cylinder 23
It is shaped in cover board 20, first connect bottom plate 12 with the bottom margin of shell wall 11 by helicitic texture or buckle structure；Again will
Sleeve 15 is set on the first cylinder 13, and is emitted for 13 a part of the first cylinder；Finally cover board 20 is from top to bottom installed again
It on shell 10, and is sheathed on the second cylinder 23 also in sleeve 15, and makes the first protrusion 131 and the second column of the first cylinder 13
Second recess portion 230 of body 23 abuts, and the second protrusion 231 of the second cylinder 23 is abutted with the first recess portion 130 of the first cylinder 13,
So that cover board 20 is covered on shell 10 and closes opening 101, the assembling process of fragrance box is completed.
As shown in Fig. 2 to 5, cover board 20 can move between the closed position and the open position relative to the shell 10.Make
When with the fragrance box, it is only necessary to rotating plate 20, until the second protrusion of the first protrusion 131 of the first cylinder 13 and the second cylinder 23
It abuts, and the first recess portion 130 is oppositely arranged with the second recess portion 230, cover board 20 increases on vertical position relative to shell 10, makes
Gap is formed between cover board 20 and shell 10, cover board 20 is in and closes open position, and the fragrance of the champignon in shell 10 passes through opening
101 and gap distribute to outside.When not needing to dissipate perfume as interior in the case where nobody, it is only necessary to rotating plate 20, until the
First protrusion 131 of one cylinder 13 and the second protrusion 231 of the second cylinder 23 misplace, and specifically, first raised 131 and second is recessed
Portion 230 abuts, and the second protrusion 231 is oppositely arranged or abuts with the first recess portion 130；Or second protrusion 231 and first recess portion
130 abut, and the first protrusion 131 is oppositely arranged or abuts with the second recess portion 230, and cover board 20 is covered on shell 10 and closes
Opening 101, cover board 20 is in the close position, and the fragrance of the champignon in shell 10 will not be distributed to outside, to can be effectively controlled
The scattered fragrant speed of champignon, extend champignon uses the time.
In other embodiments, cover board 20 can also sink relative to 101 edges of opening and carry out dissipating perfume to form gap.Tool
Body, when rotating plate 20 is in an open position, the second of the first raised 131 and second cylinder 23 of the first cylinder 13 is convex
231 dislocation are played, cover board 20 is covered on shell 10 and closes opening 101；When rotating plate 20 to closed position, the first protrusion
131 and second raised 231 abut, and gap are formed between cover board 20 and shell 10, the fragrance of the champignon in shell 10 can equally lead to
It crosses opening and gap is distributed to outside.Champignon box structure of the present invention is simple, can be effectively controlled the scattered fragrant speed of champignon, extends champignon
Use the time.
The present invention is not limited to the specific details in the above embodiment, within the scope of the technical concept of the present invention, can be with
Various simple variants of the technical solution of the present invention are made, these simple variants all belong to the scope of protection of the present invention.Above-mentioned
