[0048] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0049] The fragrance device 100 of the present invention will now be described with reference to the accompanying drawings.

[0050] like Figure 10 As shown, the fragrance device 100 according to an embodiment of the present invention includes: a fixing base 10, a first driving component 20, and a second driving component 30.

[0051] The fixed base 10 is provided with multiple holding slots 101, and the multiple holding slots 101 are arranged along a first direction (the first direction can be...). Figure 11 The containers (arranged side-by-side in the front-to-back direction) are each equipped with a sealing cover 102. The containers 101 are used to hold fragrance items, such as fragrance sticks. Multiple containers 101 can be used to hold fragrance sticks with different scents to release different fragrances. The sealing cover 102 is used to close or open the containers 101. When a selected fragrance needs to be released, the corresponding sealing cover 102 can be opened.

[0052] The first drive assembly 20 includes a first movable member 210, which can be engaged or disengaged from each sealing cap 102. When the first movable member 210 is engaged with the sealing cap 102, it can push the sealing cap 102 to open the holding slot 101. The second drive assembly 30 is disposed on the fixed base 10. The second drive assembly 30 includes a second movable member 310, which is linked to the first drive assembly 20 to drive the first drive assembly 20 to move along a first direction, so that the first movable member 210 switches between holding slots 101 at different positions.

[0053] That is, the first movable member 210 of the first driving assembly 20 can be combined with the sealing cover 102 corresponding to the selected fragrance, and the sealing cover 102 can be pushed to move by the movement of the first movable member 210 to open the holding groove 101, and the opening size between the sealing cover 102 and the holding groove 101 can be controlled by controlling the movement displacement of the first movable member 210, thereby adjusting the exposure area of the fragrance stick and controlling the release concentration of the fragrance.

[0054] When the fragrance stick of a different fragrance is selected, the second movable member 310 of the second driving assembly 30 moves to push the first driving assembly 20 to move along the first direction in which the plurality of holding grooves 101 are arranged side by side, so that the first driving assembly 20 moves to the holding groove 101 corresponding to the fragrance stick of the selected fragrance, and the sealing cover 102 is pushed away by the first movable member 210. When the fragrance stick of another fragrance is selected, the second driving assembly 30 continues to push the first driving assembly 20 to move along the first direction by a preset displacement, so that the first movable member 210 is pushed away from the sealing cover 102 and combined with another sealing cover 102 corresponding to another fragrance stick, and then the other sealing cover 102 is pushed away by the first movable member 210.

[0055] Through the multiple cooperative work of the first driving assembly 20 and the second driving assembly 30, the user can select to open the holding groove 101 corresponding to the fragrance stick of different fragrances to release a specific fragrance. In addition, the user can also select to open the plurality of holding grooves 101 in sequence to release the fragrance of the plurality of fragrance sticks, thereby forming a mixed fragrance effect.

[0056] According to the fragrance device 100 of the embodiment of the present application, the plurality of holding grooves 101 are arranged side by side along the first direction on the fixed seat 10, each holding groove 101 is provided with a sealing cover 102, the first movable member 210 of the first driving assembly 20 can be combined with or separated from each sealing cover 102, the second movable member 310 of the second driving assembly 30 is connected with the first driving assembly 20 to drive the first driving assembly 20 to move along the first direction, so that the two driving assemblies can realize the rapid switching of different fragrances, the release concentration and the mixed fragrance effect of each fragrance can be opened according to the needs of the user, the structure is simple, the control is convenient, the reliability is strong, and the cost can be saved.

[0057] In some embodiments of the present application, as shown in Figure 12 each sealing cover 102 is movably arranged on the fixed seat 10 along the second direction to open the holding groove 101, the first movable member 210 moves along the second direction, and the second direction is perpendicular to the first direction. The second direction can be Figure 1In the left-right direction, the first movable member 210 and the sealing cover 102 keep the same direction movement, which can reduce the resistance required for the first movable member 210 to push the sealing cover 102, reduce the movement complexity of the first movable member 210, and thus simplify the overall structure of the first driving assembly 20.

[0058] In some embodiments of the present application, as shown in Figure 1 The fixed seat 10 is provided with a guide structure to improve the stability of the sealing cover 102 when being opened or closed. In some examples, the guide structure includes a plurality of sliding grooves 104 provided on the fixed seat 10, and the plurality of sliding grooves 104 are one-to-one corresponding to the plurality of sealing covers 102. Each sliding groove 104 is provided with a containing groove 101, and each sliding groove 104 extends along the second direction. The sealing cover 102 is arranged in the sliding groove 104 and slides along the length direction of the sliding groove 104. The sliding groove 104 cooperates with the sealing cover 102 to realize the guiding in a simple and reliable manner.

[0059] In some examples, the guide structure can also include a groove and a sliding block. Each containing groove 101 is provided with a groove at both ends along the first direction (not shown in the figure), and the groove extends along the second direction. The sealing cover 102 is provided with a sliding block (not shown in the figure), and the sliding block is arranged at both ends of the sealing cover 102 along the first direction. The sliding block is arranged in the groove to play a guiding role and improve the reliability of the movement of the sealing cover 102.

[0060] In some embodiments of the present application, as shown in Figure 1 , Figure 1 , Figure 6 , Figure 2 Each sealing cover 102 has a first combining part 1021, and the first movable member 210 has a second combining part 2101. When the second combining part 2101 moves along the first direction, the second combining part 2101 can combine or separate from the first combining part 1021. When the second combining part 2101 moves along the second direction, the second combining part 2101 abuts against the first combining part 1021 to push the sealing cover 102 to move. That is, the movement of the second movable member 310 can realize the function of "one thing with multiple uses". That is, by using the movement of the second movable member 310 along the first direction, the first driving assembly 20 can be adjusted to different positions of the containing groove 101, and the first combining part 1021 and the second combining part 2101 can be combined or separated from the sealing cover 102 and the first movable member 210. In this way, the same number of functions can be realized, the number of components can be reduced, the structure can be simplified, and the reliability of the mechanism can be improved.

[0061] In some embodiments of the present application, as shown in Figure 3 , Figure 4 , Figure 5 , Figure 2As shown, the first coupling part 1021 is a boss, and the second coupling part 2101 includes two limiting blocks 21011 which are arranged apart along the second direction, and the boss can move into or out of the space between the two limiting blocks 21011.

[0062] As shown, in the initial position, the boss can be arranged opposite to the gap 2101a formed by the two limiting blocks 21011, and when the second movable part 310 moves a small displacement along the first direction, the first movable part 210 moves a small displacement along with the first driving assembly 20, so that the two limiting blocks 21011 move to opposite sides of the boss, i.e. the boss is just located in the gap 2101a, and the "coupling" of the first coupling part 1021 and the second coupling part 2101 is completed. Figure 3 As shown, at this time, when the first movable part 210 moves along the second direction, if it moves to the right, the sealing cover 102 can be pushed to open the containing groove 101 through the right limiting block 21011, so as to realize the "release" of the fragrance. As shown, if it moves to the left, the sealing cover 102 can be pulled to reset through the left limiting block 21011, so as to close the containing groove 101, and realize the "closing" of the fragrance.

[0063] Figure 4 As shown, when another containing groove 101 needs to be opened, the second movable part 310 continues to move a small displacement along the first direction, at this time, the first movable part 210 moves a small displacement along with the first driving assembly 20, so that the two limiting blocks 21011 can move to opposite sides away from the boss, i.e. the boss is no longer in the gap 2101a, and the "decoupling" of the first coupling part 1021 and the second coupling part 2101 is completed. Figure 5 As shown, then, the first movable part 210 moves along the second direction to adjust the second coupling part 2101 to the first coupling part 1021 of the sealing cover 102 of another containing groove 101, so that the boss is opposite to the gap 2101a of the two limiting blocks 21011, and the above-mentioned "coupling" process is repeated, and the above-mentioned "release" process or "closing" process of the fragrance is selectively repeated.

[0064] Figure 2 As shown, at this time, when the first movable part 210 moves along the second direction, if it moves to the right, the sealing cover 102 can be pushed to open the containing groove 101 through the right limiting block 21011, so as to realize the "release" of the fragrance. As shown, if it moves to the left, the sealing cover 102 can be pulled to reset through the left limiting block 21011, so as to close the containing groove 101, and realize the "closing" of the fragrance.

[0065] As shown, then, the first movable part 210 moves along the second direction to adjust the second coupling part 2101 to the first coupling part 1021 of the sealing cover 102 of another containing groove 101, so that the boss is opposite to the gap 2101a of the two limiting blocks 21011, and the above-mentioned "coupling" process is repeated, and the above-mentioned "release" process or "closing" process of the fragrance is selectively repeated. Figure 3 The above-mentioned way of arranging the first coupling part 1021 as a boss and arranging the second coupling part 2101 to include two limiting blocks 21011 makes the coupling or decoupling of the first coupling part 1021 and the second coupling part 2101 relatively simple.

[0066] The above-mentioned way of arranging the first coupling part 1021 as a boss and arranging the second coupling part 2101 to include two limiting blocks 21011 makes the coupling or decoupling of the first coupling part 1021 and the second coupling part 2101 relatively simple.

[0067] ​​In other embodiments of the present application, the first combination part 1021 can also be provided as two limiting blocks, and the second combination part 2101 is provided as a protrusion, and the operation mode is described above and will not be repeated here.

[0068] In some embodiments of the present application, as shown in Figure 4 、 Figure 5 、 Figure 5 The distance of the two limiting blocks 21011 in the second direction is greater than the width of the protrusion in the second direction. The second direction can be understood as the left-right direction shown in the figure, that is, the gap width of the gap 2101a formed by the two limiting blocks 21011 is greater than the width of the protrusion, which can ensure that the protrusion is more easily entered into the gap 2101a, improve the success rate of the combination of the first combination part 1021 and the second combination part 2101, and also facilitate the mutual disengagement of the first combination part 1021 and the second combination part 2101.

[0069] In some embodiments of the present application, as shown in Figure 2 The distance of the first combination part 1021 of any two adjacent sealing covers 102 in the first direction is greater than the width of the first movable part 210 in the second direction. The first direction can be understood as the front-back direction shown in the figure, and this mode can allow the first movable part 210 to move between the first combination part 1021 of any two adjacent sealing covers 102 in the second direction, avoiding collision between the first movable part 210 and the first combination part 1021.

[0070] In some embodiments of the present application, the distance of the first combination part 1021 of any two adjacent sealing covers 102 in the first direction can be 10 mm, and the width of the first movable part 210 in the second direction is 6 mm, then the first movable part 210 can move between any two adjacent first combination parts 1021. Of course, this is just an example, the distance of the first combination part 1021 of any two adjacent sealing covers 102 in the first direction, and the width of the first movable part 210 in the second direction can be other values, not limited to this, and will not be repeated here.
