[0038] Figure 1 is a schematic exploded view of a fragrance diffusing assembly according to an example embodiment, Figure 2 is Figure 1 is a schematic cross-sectional view of a fragrance diffusing assembly in Figure 1 and Figure 2 The fragrance diffusing assembly can include a housing 1, an oil storage member 2, a mounting bracket 3, a base 4 and a sealing top cover 5. The oil storage member 2 is fixedly arranged in the housing 1, and the base 4 is fixedly arranged below the housing 1 and the oil storage member 2, which can serve as a support for the fragrance diffusing assembly. The oil storage member 2 is arranged in the housing 1, and the gap between the outer wall of the oil storage member 2 and the inner wall of the housing 1 forms an air inlet channel 6, which is in communication with the outside. For example, the air inlet channel 6 can be arranged around the circumferential outer side of the oil storage member 2, i.e. the air inlet channel 6 can be an annular air channel. For another example, the oil storage member 2 is arranged on one side of the housing 1, and the air inlet channel 6 is arranged on the other side of the housing 1. In this way, the oil storage member 2 can be arranged as close as possible to one side of the housing 1, thereby increasing the oil storage volume of the oil storage member 2 relative to the annular air channel, and thus increasing the oil storage capacity. The base 4 is fixedly arranged relative to the oil storage member 2, and the base 4 is provided with an air inlet 41, which is in communication with the air inlet channel 6, i.e. the external airflow can enter the air inlet channel 6 through the air inlet 41.

[0039] The oil storage member 2 has an oil storage cavity 21 for storing fragrance liquid. The mounting bracket 3 is fixedly arranged relative to the oil storage member 2, and can be fixedly arranged relative to the housing 1 through the relative fixation between the mounting bracket 3 and the oil storage member 2. The mounting bracket 3 is arranged at an opening end of the oil storage cavity 21, and the mounting bracket 3 and the oil storage member 2 can be fixedly arranged relative to each other through clamping or interference fit. The mounting bracket 3 includes an annular wall 35, which can surround a fragrance diffusion cavity 31 in communication with the oil storage cavity 21. The fragrance in the oil storage cavity 21 can be diffused to the fragrance diffusion cavity 31 and then diffused to the outside of the fragrance diffusion assembly. The annular wall 35 is mainly defined as a vertical wall surrounding the depth direction of the fragrance diffusion cavity 31, and the shape of the annular wall 35 is not specifically limited. In fact, the annular wall 35 can be adaptively designed according to the shape requirements of the fragrance diffusion cavity 31.

[0040] The sealing top cover 5 can be rotatably arranged at the top of the annular wall 35, and the sealing top cover 5 is in elastic contact with the top end surface and the outer wall surface of the annular wall 35. When the sealing top cover 5 is in the open position, the fragrance in the fragrance diffusion cavity 31 can be diffused to the outside. When the sealing top cover 5 is in the closed position, the fragrance diffusion cavity 31 can be sealed by the sealing top cover 5. In this way, the sealing property of the fragrance diffusion cavity 31 can be improved by the elastic contact sealing between the sealing top cover 5 and the annular wall 35, and the risk of liquid leakage during transportation can be reduced.

[0041] In some embodiments, the top end surface and the outer wall surface of the mounting bracket 3 are both elastic contact surfaces, so as to realize the elastic contact sealing between the sealing top cover 5 and the annular wall 35.

[0042] In some embodiments, the top end surface and the outer wall surface of the mounting bracket 3 are both elastic contact surfaces, so as to realize the elastic contact sealing between the sealing top cover 5 and the annular wall 35.

[0043] In the various embodiments described above, the sealing top cover 5 can include a rigid outer cover 51 and a flexible sealing sleeve 52 fixed in the rigid outer cover 51, which is in elastic sealing contact with the top end surface and the outer wall surface of the annular wall 35. The flexible sealing sleeve 52 can include a rubber sleeve, such as a plastic sleeve or a rubber sleeve, and the rigid outer cover 51 and the flexible sealing sleeve 52 can be adhesively fixed or integrally formed, and the fixing manner is not limited. Through the sealing top cover 5 design scheme combining the rigid outer cover 51 and the flexible sealing sleeve 52, on the one hand, the elastic contact sealing can be ensured, and on the other hand, the strength design of the sealing top cover 5 is improved, which is beneficial to the smoothness of the sealing top cover 5 switching between the open position and the closed position.

[0044] In order to realize the switching between the open position and the closed position, the sealing top cover 5 further includes a rotating outer frame 53 rotatably installed on the mounting bracket 3, and the rotating outer frame 53 is arranged at the outer periphery of the rigid outer cover 51. Under the action of an external force, the rotating outer frame 53 drives the rigid outer cover 51 and the flexible sealing sleeve 52 to rotate. The rotating outer frame 53 and the rigid outer cover 51 can be connected by clamping, and the rigid outer cover 51 and the flexible sealing sleeve 52 can be driven to rotate relative to the mounting bracket 3 by the rotating outer frame 53, so as to switch the relative position between the flexible sealing sleeve 52 and the annular wall 35, and realize the opening and closing of the fragrance diffusion cavity 31.

[0045] In some embodiments, as shown in Figure 3 The rigid outer cover 51 includes a first skirt 511, and the flexible sealing sleeve 52 includes a second skirt 521 which is fitted to the inner side of the first skirt 511 and is in elastic sealing contact with the outer wall surface of the annular wall 35. For example, the first skirt 511 can be an annular skirt, and the second skirt 521 can also be an annular skirt matched with the outer wall surface of the annular wall 35, and the opening and closing of the fragrance diffusion cavity 31 can be realized by rotating the second skirt 521 along the outer wall surface of the annular wall 35; for another example, the first skirt 511 and the second skirt 521 can also be arc-shaped skirts, and the area of the arc-shaped skirt can be designed according to the closed position capable of sealing the fragrance diffusion cavity 31. The specific design can be as required, and the present disclosure does not limit it.

[0046] In order to realize the opening and closing of the fragrance cavity 31, the first skirt 511 is provided with a first through hole 512, the second skirt 521 is provided with a notch 522 and a second through hole 523, and the first through hole 512 and the second through hole 523 are communicated, for example, the first through hole 512 and the second through hole 523 can be through hole structures of the same size and alignment, and again, the first through hole 512 and the second through hole 523 can also be different in size and partially aligned, and the airflow circulation can be realized. When the sealing cover 5 is in the open position, the notch 522 can be a ventilation groove communicated with the fragrance cavity 31, and the first through hole 512 and the second through hole 523 form a diffusion port communicated with the fragrance cavity 31 and the outside. Among them, the notch 522 can also be communicated to the air inlet channel 6, so that the natural wind can enter the fragrance cavity 31 through the ventilation groove, mix the fragrance flavor, and then diffuse through the diffusion port to enter the outside, thereby realizing fragrance diffusion. The structure of the ventilation groove and the diffusion port is designed differently, so that the natural wind entering the air inlet channel 6 always enters through the ventilation groove and diffuses through the diffusion port, realizing the consistency of the air path design, avoiding the internal airflow from being chaotic, and affecting the fragrance effect.

[0047] As shown in Figure 4 and Figure 5 , for the air path design of the fragrance diffusion assembly in the present disclosure, the mounting bracket 3 further comprises a ventilation channel 32 arranged outside the fragrance cavity 31, and an annular wall 35 is arranged between the fragrance cavity 31 and the ventilation channel 32, that is, the inner wall of the annular wall 35 can form the inner wall of the fragrance cavity 31, and the outer wall surface of the annular wall 35 can form the inner wall of the ventilation channel 32. The notch 522 on the second skirt 521 of the flexible sealing sleeve 52 serves as a ventilation groove and is communicated with the ventilation channel 32. The annular wall 35 further comprises an air inlet 33 and a fragrance outlet 34. When the sealing cover 5 is in the open position, the ventilation channel 32 and the air inlet 33 are communicated through the notch 522 of the second skirt 521 to realize air inlet, and the diffusion port formed by the first through hole 512 and the second through hole 523 is communicated with the fragrance outlet 34, so that the airflow in the fragrance cavity 31 can enter the outside through the fragrance outlet 34 and the diffusion port, that is, the air path at this time is: air inlet channel 6-ventilation channel 32-notch 522-air inlet 33-fragrance cavity 31-fragrance outlet 34-second through hole 523-first through hole 512-outside. When the sealing cover is in the closed position, the ventilation groove and the air inlet 33 are completely misaligned, and at this time the air inlet 33 can be sealed by the second skirt 521 of the flexible sealing sleeve 52, and the fragrance outlet 34 and the diffusion port are also completely misaligned, and the fragrance outlet 34 can be sealed by the second skirt 521 of the flexible sealing sleeve 52, and the annular wall 35, the fragrance outlet 34 and the air inlet 33 are elastically sealed by the sealing cover 5.

[0048] Further, the ventilation channel 32 is in communication with the fragrance outlet 34 and the air inlet 33, and the fragrance outlet 34 is coincident with the air inlet 33 after rotating 180° around the axis of the annular wall 35, that is, the fragrance outlet 34 and the air inlet 33 are centrally symmetrically arranged on the annular wall 35. Based on this, assuming Figure 4 and Figure 5 the embodiment shown is the sealing top cover 5 in the normal position, then as shown in Figure 6 and Figure 7 based on the embodiment shown in Figure 4 and Figure 5 when the sealing top cover 5 is reversed and rotated 180°, the fragrance outlet 34 in the embodiment shown in Figure 4 and Figure 5 becomes the air inlet in the embodiment shown in Figure 6 and Figure 7 the air inlet 33 in the embodiment shown in Figure 4 and Figure 5 becomes the fragrance outlet in the embodiment shown in Figure 6 and Figure 7 , that is, the air path at this time is: air inlet 6-ventilation channel 32-gap 522-air inlet 33-fragrance cavity 31-fragrance outlet 34-second through hole 523-first through hole 512-external environment.

[0049] In this way, the air path design can be achieved in the case of the sealing top cover 5 in the normal position or reversed, fragrance can be diffused, and the installation requirements are reduced.

[0050] In each of the above embodiments, the fragrance diffusing assembly further comprises a hard fiber fragrance stick 7 and a sealing ring 8, the sealing ring 8 seals the open end of the oil storage cavity 21 and is connected with the mounting bracket 3, the sealing ring 8 is clamped and fixed with the mounting bracket 3, the hard fiber fragrance stick 7 extends from the sealing ring 8 and is partially located in the fragrance cavity 31, and the hard fiber fragrance stick 7 is in interference fit with the sealing ring 8. In this way, the use of the hard fiber fragrance stick 7 can improve the strength, and is conducive to reducing the risk of breakage of the hard fiber fragrance stick 7 during interference assembly between the hard fiber fragrance stick 7 and the sealing ring 8.

[0051] Further, the fragrance diffusing assembly further comprises a heating wire 9, the heating wire 9 is wound around one end of the hard fiber fragrance stick 7 located in the fragrance cavity 31, and the heating wire 9 is fixedly connected with the mounting bracket 3, so that on the one hand the fixing of the heating wire 9 can be realized through the mounting bracket 3, and on the other hand the heating of the fragrance oil can be realized through the heating wire 9, thereby realizing fragrance diffusion.

[0052] Based on the technical solutions of the present disclosure, a fragrance machine is also provided, which can include the host and the host in any of the foregoing embodiments. The host is electrically connected with the fragrance diffusion assembly to realize the fragrance diffusion control of the fragrance machine, such as the fragrance diffusion time length, fragrance diffusion concentration, etc. The host and the fragrance diffusion assembly can be connected in a detachable manner to facilitate the replacement of the fragrance diffusion assembly or the addition of fragrance liquid after the fragrance liquid is used up. When the host and the fragrance diffusion assembly are detachably connected, the electrical conduction between the host and the fragrance diffusion assembly can be realized when the fragrance diffusion assembly is assembled in the host. The fragrance machine can be a vehicle-mounted fragrance machine or a household fragrance machine, and the present disclosure does not limit this.
