[0043] The object of the present application is to provide an odor release device, which is lightweight and convenient to carry and move. It has an ovoid-shaped housing, with the thickness increasing gradually below the waist, and the bottom and both sides presenting an arc shape. A counterweight is arranged at the bottom to make the center of gravity stable, not easily toppled, and capable of continuously shaking without power, thereby promoting the slow release of the fragrance.

[0044] The odor release device proposed in the present application, such as Figure 1 and Figure 2As shown in the figure, it includes an odor container 40, a counterweight 30, and a housing 70. The odor container 40 is used to contain odor substances, mainly fragrances, and to slowly release the odor substances.

[0045] housing 70

[0046] As Figure 1 shown in Figure 2 the figure, the housing 70 includes a first housing 10 and a second housing 20.

[0047] The first housing 10 has a first panel 11, and the side edge of the first panel 11 extends towards the second housing 20. Preferably, the side edge extends towards the second housing 20 in an arc shape, with a more rounded shape. Of course, the radius of the rounded corner formed by this arc shape can be large or small. The larger the radius of the rounded corner, the more rounded the structure; the smaller the radius of the rounded corner, the more square the structure; it is of course also possible to reduce the radius of the rounded corner so that it approaches a right angle.

[0048] As Figure 2 shown in Figure 5 the figure, the second housing 20 has a second panel 21, and the side edge of the second panel 21 extends towards the first housing 10. Preferably, the side edge extends towards the first housing 10 in an arc shape, with a more rounded shape. Similarly, the radius of the rounded corner formed by this arc shape can be large or small. The larger the radius of the rounded corner, the more rounded the structure; the smaller the radius of the rounded corner, the more square the structure; it is of course also possible to reduce the radius of the rounded corner so that it approaches a right angle.

[0049] As Figure 2 shown in Figure 3 the figure, the first panel 11 is also provided with a hollow structure 13 for the gas flow inside and outside the housing 70, so that the fragrance can diffuse from inside the housing 70 to the external environment. The form of the hollow structure 13 is not limited. It can be a complex hollow pattern line, or a simple round hole; even for a round hole, it can be made into different sizes, such as Figure 1 shown in Figure 3 the figure; or change the arrangement form to make the hollow structure 13 more aesthetic and interesting.

[0050] As Figure 2 shown in the figure, the first housing 10 and the second housing 20 both have a gradually increasing thickness from the waist downwards, so that the bottom volume and area are both increased, effectively reducing the center of gravity.

[0051] As Figure 2As shown, the side edges of the second housing 20 and the first housing 10 can be detachably engaged with each other. The engagement method is not limited, and common means such as hooks and slots, protrusions and recesses can be used. When designing specifically, the elasticity and rigidity of the second housing 20 and the first housing 10 also need to be considered. More importantly, in this application, the positions of mutual engagement should be set at the top and both sides of the second housing 20 and the first housing 10, as Figure 2 shown, but not at the bottom because the bottom has other uses, which will be described later.

[0052] After the first housing 10 and the second housing 20 are mutually engaged, a receiving space with a thinner upper part and a thicker lower part is formed inside the housing 70. The receiving space is provided with a first positioning structure 23 and a lower second positioning structure 24, as Figure 2 shown. The first positioning structure 23 is used to set the odor container 40, and the second positioning structure 24 is used to set the counterweight 30.

[0053] As Figure 4 shown, a set of pivot devices 73 are also provided near the bottom inside the receiving space, which are respectively connected to the bottom positions of the first housing 10 and the second housing 20. When the mutual engagement between the first housing 10 and the second housing 20 is released, the first housing 10 and the second housing 20 can be opened with the pivot device 73 as the rotation axis. This structure is convenient for taking out the used odor container 40 and putting in a new odor container 40. After the replacement of the odor container 40 is completed, as long as the first housing 10 and the second housing 20 are mutually engaged again with the pivot device 73 as the rotation axis, the original state can be restored.

[0054] Furthermore, as Figure 3 shown, a plurality of first longitudinal limiting claws 15 are also provided inside the first housing 10 facing the odor container 40, which are used to abut against the flange 411 of the odor container 40 to limit the longitudinal movement of the odor container 40.

[0055] counterweight 30

[0056] As Figure 2 shown, the counterweight 30 is an important component for this application to form a tumbler shape. It is preferably made of a metal material and has a relatively heavy weight. The counterweight 30 is set in the second positioning structure 24. Because of its low position and heavy weight, and at the same time the housing 70 has a relatively large bottom volume and area, and a circular arc-shaped bottom side edge. Therefore, when an external force gently pushes the housing 70, the housing 70 can generate slow reciprocating swings and gradually return to its equilibrium position. Such reciprocating swings are beneficial to the slow release of the fragrance by the odor container 40 inside the housing 70.

[0057] odor container 40

[0058] As Figure 2 andFigure 3 As shown, the scent container 40 is disposed in the first positioning structure 23 and has a breathable surface 41 for releasing fragrance.

[0059] The shape of the scent container 40 is not limited. In a preferred embodiment, the scent container 40 includes a flat cylindrical body 42. The body 42 has a longitudinal direction along the axis of the cylinder and a transverse direction perpendicular to the axis of the cylinder, which can also be said to be the radial direction of the cylinder.

[0060] The breathable surface 41 is disposed on one side of the body 42 in the longitudinal direction facing the first housing 10. More specifically, it faces the hollow structure 13 of the first panel 11. Thus, the released fragrance can be dispersed into the environment through the hollow structure 13. It should be reminded that since the housing 70 has a tumbler shape and the thickness below the waist gradually increases, the first panel 11 is not vertical but forms an inclination angle with the vertical plane. Therefore, the breathable surface of the scent container 40 is not vertical either and also forms an inclination angle with the vertical plane, especially preferably parallel to the hollow structure 13 of the first panel 11. More specifically, the scent container 40 itself presents an inclined positioning state in the first positioning structure.

[0061] The breathable surface 41 further extends a flange 411 outward along the transverse direction of the body 42, and the first longitudinal limiting claw 15 inside the first housing 10 abuts against the flange 411. On the other hand, the second longitudinal limiting claw 232 of the second positioning structure 23 abuts against the bottom of the body 42. By means of the first longitudinal limiting claw 15 and the second longitudinal limiting claw 232, the movement of the body 42 along the longitudinal direction can be restricted.

[0062] Furthermore, the transverse limiting claw 234 of the second positioning structure 23 abuts against the outer edge of the body 42 from multiple positions to restrict the body 42 from moving along the transverse direction.

[0063] Still further, the flange 411 further extends a convex tooth 412, and the card slot 233 of the first positioning structure 23 catches the convex tooth 412, thereby restricting the body 42 from rotating with the longitudinal axis of the body as the rotation axis.

[0064] Through the first longitudinal limiting claw 15, the second longitudinal limiting claw 232, the transverse limiting claw 234, and the card slot 233, the scent container 40 can be stably positioned in the accommodating space of the housing 70. Even if the housing 70 shakes due to an external force, the scent container 40 only shakes correspondingly with the housing 70 and does not vibrate and collide inside the housing 70.

[0065] first positioning structure 23

[0066] Such as Figure 2 And Figure 6As shown, the first positioning structure 23 is disposed inside the second housing 20, at a position higher than the second positioning structure 24. The first positioning structure 23 includes a limiting ring 231. The limiting ring 231 does not need to be a complete circular ring and may also be composed of a plurality of arc segments. The limiting ring 231 extends a plurality of lateral limiting claws 234 towards the first housing 10, and a plurality of second longitudinal limiting claws 232 are further disposed inside the limiting ring 231.

[0067] The lateral limiting claws 234 are used to abut against the outer edge of the body 42 of the scent container 40, and can limit the body 42 from moving laterally. The second longitudinal limiting claws 232 are used to abut against the bottom of the body 42 of the scent container 40. Through the second longitudinal limiting claws 232 and the first longitudinal limiting claws 15 of the first housing 10, the body 42 can be limited from moving longitudinally.

[0068] In one embodiment, the first positioning structure 23 further includes a card slot 233, which is disposed outside the limiting ring 231. When considering space limitations, it is preferably disposed above the limiting ring 231, but this is not limiting. The position and the opening shape of the card slot 233 correspond to the convex teeth 412 of the scent container 40. When the scent container 40 is placed into the first positioning structure 23, the convex teeth 412 are also engaged into the card slot 233, thereby limiting the body 42 from rotating about the longitudinal axis of the body.

[0069] second positioning structure 24

[0070] As Figure 2 and Figure 6 described, the second positioning structure 24 is disposed inside the second housing 20, at a position near the bottom, for mounting the counterweight 30. Therefore, its structural form must match the form of the counterweight 30 and ensure that the counterweight 30 does not shake. In one embodiment, as Figure 2 shown, when the counterweight 30 is a cuboid, the second positioning structure 24 has a groove-shaped space 241, and the counterweight 30 is disposed inside the groove-shaped space 241.

[0071] extension member 50

[0072] As Figure 1 and Figure 2As shown, in an alternative embodiment, the odor release device proposed in the present application further includes a protruding member 50, which serves as an operating rod for swinging the operating housing 70. At this time, the housing 70 further includes at least one opening 71, which is provided at a position near the top of the housing 70. The opening 71 can be provided in the first housing 10, or in the second housing 20, or can be formed by hollowing out both the first housing 10 and the second housing 20. The protruding member 50 is connected to the inside of the housing 70. More specifically, it is connected to either the first housing 10 or the second housing 20. One end of the protruding member 50 extends out of the opening 71 for easy manual operation. Preferably, the number of openings 71 is two, symmetrically arranged on both sides of the housing 70 near the top. At this time, both ends of the protruding member 50 extend out of the openings 71 respectively.

[0073] The connection between the protruding member 50 and the inside of the housing 70 can be a fixed connection, such as Figure 2 as shown, there are two connection points; it can also be a single-point pivot connection. If a pivot connection is adopted, the opening 71 can be made larger so that both ends of the protruding member 50 can swing left and right at the opening 71 with the pivot as the rotation center, increasing the fun of use.

[0074] In summary, the odor release device proposed in the present application is lightweight, easy to carry and move. It has an egg-shaped housing with a gradually wider thickness below the waist, and the bottom and both sides are arc-shaped. The counterweight is arranged at the bottom to make the center of gravity stable, not easy to topple, and can continuously shake without power. The odor container is placed inside the housing, and a hollow structure is also provided on the surface of the housing. Through the slight shaking of the egg-shaped device, the odor container slowly releases the fragrance, and then through the hollow structure and air convection, the fragrance is dispersed into the ambient air.

[0075] The detailed description of the above preferred specific embodiments is intended to more clearly describe the features and spirit of the present application, rather than to limit the scope of the present application by the above-disclosed preferred specific embodiments. On the contrary, the purpose is to cover various equivalent changes within the scope of the claims that the present application intends to claim.
