DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0025] Embodiment one

[0026] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , a switchable fragrance device comprises a fragrance box assembly 1, a diffusion assembly 2 and a fragrance switching mechanism, the fragrance switching mechanism comprises a material rotating disc 3, a sealing valve 4 and a driving mechanism 5; the material rotating disc 3 is provided with a main shaft 31 in the center, and a plurality of fragrance box assemblies 1 are arranged on the edge of the material rotating disc 3 in the circumferential direction; the material rotating disc 3 is rotatably connected with the main shaft 31; each fragrance box assembly 1 is provided below with a sealing valve 4; the sealing valve 4 comprises a sealing orifice 41 and a spherical sealing element 42; the sealing orifice 41 is a through hole opened on the material rotating disc 3, and the maximum inner diameter thereof is smaller than the outer diameter of the spherical sealing element 42; the spherical sealing element 42 is placed above the sealing orifice 41; the diffusion assembly 2 is arranged below the material rotating disc 3 and on the circumference formed by the fragrance box assemblies 1, that is, the material rotating disc 3 rotates one circle, and each fragrance box assembly 1 will pass above the diffusion assembly 2;

[0027] In practical applications, when the spherical seal 42 is placed in the sealing orifice 41, a portion of it will pass through the sealing orifice 41. The distance between the uppermost end of the diffusion assembly 1 and the rotating disk 3 is less than the straight-line distance from the lowermost end of the spherical seal 42 to the lower surface of the rotating disk 3. The driving mechanism 5 drives the rotating disk 3 to rotate. When a certain spice box assembly 1 rotates to directly above the diffusion assembly 2, the spherical seal 42 is lifted up by the diffusion assembly 2 below it (e.g., Figure 4 (As shown), this opens the sealing orifice 41;

[0028] After the spice box assembly 1 moves away from the diffuser assembly 2, the spherical seal 42 falls down, resealing the sealing orifice 41 (as shown). Figure 3 As shown), this reduces the volatilization of fragrance consumables in the fragrance box assembly 1; the rotation of the transfer plate 3 can switch the fragrance box assembly 1 located above the diffusion assembly 2, and this repetition can achieve the switching of different fragrances;

[0029] In practical applications, the edge shape of the sealing orifice 41 fits the surface of the spherical seal 42, which can increase the contact area between the two and make the sealing valve 4 have a better sealing effect. The spherical seal 42 is made of stainless steel, which has a high density and is relatively heavy for the same volume. It has a good sealing effect, is corrosion resistant, and can be used for a long time.

[0030] The fragrance box assembly 1 is provided with a cover plate 11, forming a relatively enclosed small space. A mesh 12 is provided inside this space. The cover plate 11 is provided with openings for diffusing fragrance. The mesh 12 can separate the spherical seal 42 and the fragrance consumables in the fragrance box assembly 1 to prevent them from contacting each other, and can also restrict the movement space of the spherical seal 42.

[0031] In practical applications, the main body of the spice box assembly 1 is integrated with the transfer tray 3. The cover plate 11 is fixed to the main body of the spice box assembly 1 with a snap fastener, which makes it convenient for users to replace consumables.

[0032] When a fragrance box assembly 1 rotates above the diffusion assembly 2, the spherical seal 42 is lifted, the sealing orifice 41 is opened, and the diffusion assembly 2 generates an upward blowing airflow that enters the fragrance box assembly 1 through the sealing orifice 41 to help diffuse the scent; a guide tube 111 is provided above the opening of the cover plate 11, which can make the airflow carrying the fragrance scent diffuse more concentratedly to the outside of the fragrance device.

[0033] Furthermore, an outer cover 6 is provided above the transfer tray 3 to cover the transfer tray 3 and the fragrance box assembly 1, forming a relatively closed space. This serves to prevent dust and moisture and to avoid the mixing and volatilization of various different fragrances, which could cause cross-contamination. A diffuser 61 is provided on its upper side. Only when the fragrance box assembly 1 rotates to be directly above the diffuser assembly 2 will the guide tube 111 be aligned with the diffuser hole, and the fragrance device will start working. In this way, it can be ensured that only one fragrance box assembly 1 has a smooth airflow channel at the same time, that is, only one fragrance box assembly 1 is in working state. Moreover, the full fit between the guide tube 111 and the diffuser hole can play a certain sealing role, preventing the fragrances in other fragrance box assemblies 1 from diffusing together and causing cross-contamination.

[0034] The diffusion assembly 2 includes a diffusion fan 21, and a fan cover 22 is provided above the diffusion fan 21. The fan cover 22 has two main functions: first, to allow the airflow to pass through the spice box assembly 1 more concentratedly; and second, to lift the spherical seal 42, so that the sealing valve 4 can be opened, allowing the airflow to pass through the spice box assembly 1 above.

[0035] The drive assembly includes a drive motor 51, a drive wheel 52, and a driven wheel 53. The drive wheel 52 is fixed to the drive shaft of the drive motor 51, and the driven wheel 53 is concentrically fixed to the rotating disc 3. The drive wheel 52 and the driven wheel 53 mesh, so that the drive motor 51 drives the driven wheel 53 through the drive wheel 52, thereby causing the rotating disc 3 to rotate around the main shaft 31.

[0036] Example 2

[0037] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a switchable fragrance device includes a fragrance box assembly 1, a diffusion assembly 2, and a fragrance switching mechanism. The fragrance switching mechanism includes a rotating disc 3, a sealing valve 4, and a driving mechanism 5. A main shaft 31 is arranged at the center of the rotating disc 3, and several fragrance box assemblies 1 are arranged circumferentially along its edge. The rotating disc 3 is rotatably connected to the main shaft 31. A sealing valve 4 is arranged below each fragrance box assembly 1. The sealing valve 4 includes a sealing orifice 41 and a spherical seal 42. The sealing orifice 41 is a through hole opened on the rotating disc 3, and its maximum inner diameter is smaller than the outer diameter of the spherical seal 42. The spherical seal 42 is placed above the sealing orifice 41. The diffusion assembly 2 is arranged below the rotating disc 3 and is located on the circumference formed by the fragrance box assemblies 1, that is, when the rotating disc 3 rotates once, each fragrance box assembly 1 will pass over the diffusion assembly 2.

[0038] In practical applications, when the spherical seal 42 is placed in the sealing orifice 41, a portion of it will pass through the sealing orifice 41. The distance between the uppermost end of the diffusion assembly 1 and the rotating disk 3 is less than the straight-line distance from the lowermost end of the spherical seal 42 to the lower surface of the rotating disk 3. The driving mechanism 5 drives the rotating disk 3 to rotate. When a certain spice box assembly 1 rotates to directly above the diffusion assembly 2, the spherical seal 42 is lifted up by the diffusion assembly 2 below it (e.g., Figure 4 (As shown), this opens the sealing orifice 41;

[0039] After the spice box assembly 1 moves away from the diffuser assembly 2, the spherical seal 42 falls down, resealing the sealing orifice 41 (as shown in the sealed state). Figure 3 As shown), this reduces the volatilization of fragrance consumables in the fragrance box assembly 1; the rotation of the transfer plate 3 can switch the fragrance box assembly 1 located above the diffusion assembly 2, and this repetition can achieve the switching of different fragrances;

[0040] In practical applications, the edge shape of the sealing orifice 41 fits the surface of the spherical seal 42, which can increase the contact area between the two and make the sealing valve 4 have a better sealing effect. The spherical seal 42 is made of stainless steel, which has a high density and is relatively heavy for the same volume. It has a good sealing effect, is corrosion resistant, and can be used for a long time.

[0041] The fragrance box assembly 1 is provided with a cover plate 11, forming a relatively enclosed small space. A mesh 12 is provided inside this space. The cover plate 11 is provided with openings for diffusing fragrance. The mesh 12 can separate the spherical seal 42 and the fragrance consumables in the fragrance box assembly 1 to prevent them from contacting each other, and can also restrict the movement space of the spherical seal 42.

[0042] In practical applications, the main body of the spice box assembly 1 is integrated with the transfer tray 3. The cover plate 11 is fixed to the main body of the spice box assembly 1 with a snap fastener, which makes it convenient for users to replace consumables.

[0043] When a fragrance box assembly 1 rotates above the diffusion assembly 2, the spherical seal 42 is lifted, the sealing orifice 41 is opened, and the diffusion assembly 2 generates an upward blowing airflow that enters the fragrance box assembly 1 through the sealing orifice 41 to help diffuse the scent; a guide tube 111 is provided above the opening of the cover plate 11, which can make the airflow carrying the fragrance scent diffuse more concentratedly to the outside of the fragrance device.

[0044] Furthermore, an outer cover 6 is provided above the transfer tray 3 to cover the transfer tray 3 and the fragrance box assembly 1, forming a relatively closed space. This serves to prevent dust and moisture and to avoid the mixing and volatilization of various different fragrances, which could cause cross-contamination. A diffuser 61 is provided on its upper side. Only when the fragrance box assembly 1 rotates to be directly above the diffuser assembly 2 will the guide tube 111 be aligned with the diffuser hole, and the fragrance device will start working. In this way, it can be ensured that only one fragrance box assembly 1 has a smooth airflow channel at the same time, that is, only one fragrance box assembly 1 is in working state. Moreover, the full fit between the guide tube 111 and the diffuser hole can play a certain sealing role, preventing the fragrances in other fragrance box assemblies 1 from diffusing together and causing cross-contamination.

[0045] The diffusion assembly 2 includes a diffusion fan 21, and a fan cover 22 is provided above the diffusion fan 21. The fan cover 22 has two main functions: first, to allow the airflow to pass through the spice box assembly 1 more concentratedly; and second, to lift the spherical seal 42, so that the sealing valve 4 can be opened, allowing the airflow to pass through the spice box assembly 1 above.

[0046] The drive assembly includes a drive motor 51, a drive wheel 52, and a driven wheel 53. The drive wheel 52 is fixed to the drive shaft of the drive motor 51, and the driven wheel 53 is concentrically fixed to the rotating disc 3. The drive wheel 52 and the driven wheel 53 mesh, so that the drive motor 51 drives the driven wheel 53 through the drive wheel 52, thereby causing the rotating disc 3 to rotate around the main shaft 31.

[0047] Alternatively, when the fragrance device is small and the internal space is insufficient to install a motor and gear set, a mechanism such as a lever or knob can be used to connect to the main shaft 31, and the fragrance type can be switched by manually rotating the transfer plate 3.

[0048] Preferably, the structure of the fragrance device of this application can also be cleverly combined with the humidifier components to form a multi-purpose fragrance humidifier;

[0049] The humidifier assembly includes a water tank 71, a water guide rod 72, and an ultrasonic atomizer 73; wherein the water tank 71 can be integrated with the fragrance diffuser housing; the main shaft 31 of the transfer disc 3 is designed as a hollow tubular structure, and the water guide rod 72 is disposed in the main shaft 31; the specific structure of the ultrasonic humidifier is not limited to the one shown in the accompanying drawings of this application.

[0050] Furthermore, a water level detection sensor 74 is installed in the water tank 71 to detect the water level in the water tank 71. When the water level in the water tank 71 is lower than the minimum water level, the humidifier will automatically stop working.

[0051] Advantages of this utility model:

[0052] Multiple fragrance box assemblies are arranged on a rotating tray, and the combination of the rotating tray structure and the diffusion assembly enables the switching of different fragrances. A spherical seal is set in the fragrance box assembly to form a sealing valve. The gravity of the spherical seal achieves the sealing of the fragrance box assembly, effectively preventing the cross-contamination of different fragrances. The spherical seal is lifted only when the fragrance box assembly rotates onto the diffusion assembly, and the fragrance box assembly at that point is open, while the sealing valves of the other fragrance box assemblies are closed. The main shaft of the rotating tray is hollow and can be combined with the humidifier assembly to enrich functions and expand the application scenarios.

[0053] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
