In addition, the terms "first", "second" are only used to distinguish in the description, and have no special meaning.

[0038] As Figures 1 to 4 The utility model provides a kind of fragrance device, including shell 100, fragrance device further includes containing component and adjusting component installed in shell 100.Wherein, containing component includes containing box 210 and obstruction piece, containing cavity 211 of containing box 210 contains perfume 230, obstruction piece can be relatively active with containing box 210, when perfume 230 emits smell can be discharged containing box 210, obstruction piece is at first position, containing box 210 is closed space when obstruction piece is at second position;Adjusting component includes camshaft 310 and reset mechanism 320, camshaft 310 is rotatably connected with shell 100, cam 311 of camshaft 310 can drive obstruction piece to move to first position, reset mechanism 320 makes obstruction piece can move to second position.

[0039] Exemplary, camshaft 310 includes shaft portion 312 and cam 311, cam 311 is fixedly installed on shaft portion 312, the axis of shaft portion 312 is the rotation axis of cam 311, shaft portion 312 is rotatably connected with shell 100;The circumferential wall of cam 311 is in contact with obstruction piece, the circumferential profile of cam 311 at least includes first point position and second point position, on the axial projection of shaft portion 312, the distance L1 of first point position from the rotation center of cam 311, satisfies L1>L2, L2 is the distance of second point position from the rotation center of cam 311.Set, when first point position acts on obstruction piece, obstruction piece is lifted by cam 311, obstruction piece is spaced apart from containing box 210, gap appears between the two, forms gas flow channel, so that the smell of perfume 230 can be discharged containing box 210, in turn discharge shell 100.When first point position is away from obstruction piece, second point position is close to obstruction piece, obstruction piece gradually loses the force of cam 311, and reset mechanism 320 can drive obstruction piece to be close to containing box 210, until containing box 210 is closed, to prevent the smell of perfume 230 from overflowing containing box 210.

[0040] Thus, since the circumferential profile of cam is circular arc, first point position to second point position is circular arc transition, so that user can realize the opening of containing box 210 infinite adjustment, in turn can more detailedly adjust the smell concentration of perfume 230 volatilization.

[0041] It needs to be explained that, in the embodiment, the process that perfume 230 emits smell can include the process that solid-state perfume 230 gradually sublimates into gaseous perfume 230, and can also include the process that liquid-state perfume 230 gradually vaporizes into gaseous perfume 230.

According to the use requirements of the user, one or more containing cavities 211 can be selectively opened.

[0044] It should be noted that the pollution between the spices 230 refers to the change in the taste of the spices 230 after two spices 230 with different tastes are mixed.

[0045] Further, the containing box 210 is integrally formed with the shell 100. The shell 100 includes a shell main body 102 and a top cover 101, and the top cover 101 and the shell main body 102 are detachably installed; the containing box 210 includes a circumferential side wall and a baffle, the circumferential side wall surrounds a cylindrical space, and the opposite sides of the baffle are sealingly connected with the circumferential side wall, so as to divide the cylindrical space into a plurality of subspaces, and the bottom of the circumferential side wall is fixed to the bottom wall of the shell main body 102. When the top cover 101 of the shell 100 is fixedly buckled with the shell main body 102, the top cover 101 can seal the top of the circumferential side wall. The plurality of subspaces are a plurality of relatively independent fragrance cavities. When it is necessary to replace the spices 230 in the fragrance cavities, the top cover 101 of the shell 100 can be opened.

[0046] In another embodiment, the containing box 210 is relatively independent of the shell 100, and the outer wall of the containing box 210 surrounds a relatively closed space.

[0047] For example, the containing box 210 includes three containing cavities 211, which are respectively referred to as a first containing cavity, a second containing cavity and a third containing cavity, and the spices 230 are provided with three spices 230 with different tastes, which are respectively referred to as a first spice, a second spice and a third spice. Among them, the first spice is placed in the first containing cavity, the second spice is placed in the second containing cavity, and the third spice is placed in the third containing cavity.
