Description

Technical Field

[0001] This application relates to the field of fragrance-related technology, and in particular to a fragrance diffuser. Background Technology

[0002] Existing aroma diffusers typically employ a double-shell rotating structure, comprising an upper and lower shell that can rotate relative to each other, forming a fragrance chamber for containing incense. The shells have fragrance diffusers with openings communicating with the fragrance chamber, and fan blades are installed within the airflow channel between the diffusers and the fragrance chamber. When the two shells rotate relative to each other, the fan blades are driven to rotate, enhancing the fragrance's evaporation effect. However, this existing technology has drawbacks: it cannot prevent fragrance evaporation when not in use, leading to unnecessary fragrance loss; or the user needs to open the diffuser before use and close it afterward, resulting in cumbersome operation. Utility Model Content

[0003] The main technical problem this application addresses is that in existing aroma diffusers, opening and closing the fragrance outlet and driving the fan blades require separate operations, which is cumbersome.

[0004] To solve the above-mentioned technical problems, this application provides an aroma diffuser, comprising:

[0005] The outer shell includes a first shell and a second shell that rotate relative to each other, the first shell and the second shell being connected to form a receiving cavity; the receiving cavity includes a fragrance area and an airflow channel, the fragrance area being used to contain fragrance; the outer shell is provided with a fragrance dispersing port communicating with the fragrance area;

[0006] Fan blades are located within the airflow channel;

[0007] A transmission mechanism is provided, wherein the fan blades are connected to the transmission mechanism, and the transmission mechanism is connected to the first housing and the second housing respectively;

[0008] A stop is provided inside the receiving cavity and is movably connected to the first housing.

[0009] When the first housing rotates relative to the second housing, it can drive the transmission structure and the stop to move simultaneously; the first housing drives the stop to move closer to or further away from the fragrance vent to close or open the fragrance vent; the rotation of the first housing relative to the second housing drives the transmission mechanism to rotate, thereby driving the fan blades to rotate.

[0010] Optionally, the transmission mechanism includes an internal gear and a first gear. The internal gear is disposed on the first housing, and the first gear is rotatably disposed on the second housing and connected to the fan blade. The first gear is drivenly connected to the internal gear.

[0011] Further optionally, the first housing includes a cover and an annular frame, the cover being fixedly connected to the annular frame, the inner side of the annular frame communicating with the fragrance vent and the fragrance area; the fragrance vent is located on the cover, the internal tooth portion is located on the inner side of the annular frame, and the first gear is located inside the annular frame.

[0012] Further optionally, the stop is movably connected to the annular frame and can move inside the annular frame; the stop has a sliding protrusion on the side near the annular frame, and the annular frame has a sliding groove on the side near the stop, the sliding protrusion engaging with the sliding groove and sliding within the groove; or, the stop has a sliding groove on the side near the annular frame, and the annular frame has a sliding protrusion on the side near the stop, the sliding protrusion being located within the sliding groove, the sliding protrusion engaging with the sliding groove and sliding within the sliding groove; when the first housing moves relative to the second housing, the annular frame and the cover move together, driving the stop to move, thereby closing or opening the fragrance vent.

[0013] Optionally, the fragrance vent is located at the top of the cover; the slide is spirally arranged along the circumference of the annular frame and extends in the direction close to the fragrance vent; when the first housing rotates relative to the second housing, the rotation of the first housing drives the stop to move up and down in the direction close to or away from the fragrance vent.

[0014] Optionally, the outer casing further includes a grille, which is movably disposed at the fragrance vent and fixedly connected to the second casing. The grille has multiple first through holes communicating with the fragrance area. The baffle has multiple stops, each corresponding to one of the first through holes. When a stop is connected to the sidewall corresponding to a first through hole, the fragrance vent is closed. When a stop is offset from the sidewall corresponding to a first through hole, the fragrance vent is opened.

[0015] Alternatively, the transmission mechanism may further include a second gear, wherein the first gear is located at the middle position of the internal gear portion, the second gear meshes with the first gear, and the second gear is connected to the internal gear portion in a transmission connection.

[0016] Further optionally, the second housing is provided with an arc-shaped groove, and the second gear is provided with a protrusion on the side near the second housing. The protrusion slides in the arc-shaped groove. The arc-shaped groove has a starting end and an ending end. The protrusion is located at the starting end. The second gear meshes with the first gear. The protrusion is located at the ending end. The second gear is offset from the first gear.

[0017] Further optionally, when the protrusion is located at the starting end, the baffle is configured to block the fragrance vent; when the protrusion is located at the end, the baffle is configured to detach from the sidewall surrounding the fragrance vent.

[0018] Further optionally, the first housing is provided with two first interference portions on one side of the receiving cavity, the two first interference portions protruding from the first housing and located on opposite sides of the aroma diffuser in the radial direction, the second housing is provided with a second interference portion, the second interference portion being located between the two first interference portions, and when the first interference portion contacts the second interference portion, it blocks the relative rotation of the first housing and the second housing.

[0019] The beneficial effects of this application are:

[0020] By setting the first and second housings to move relative to each other, and connecting the first and second housings with a transmission mechanism, the fan blades are mounted on the transmission mechanism, and a stop is movably connected to the first housing. When the first housing rotates relative to the second housing, it can drive the transmission mechanism and the stop to move simultaneously. This allows the user to simultaneously open and close the fragrance vent and drive the fan blades with only a single action of driving the first and second housings to move relative to each other, without the need for separate operations. This reduces the ineffective volatilization of fragrance, lowers the complexity of user operation, and improves the fragrance dispersal efficiency. Attached Figure Description

[0042] Aroma diffusers typically have a fragrance chamber to hold fragrances, and a fragrance diffuser 14 is provided on the outer casing 1 of the aroma diffuser. The fragrance diffuser 14 is connected to the fragrance chamber so that the fragrance of the fragrance can diffuse to the outside through the fragrance diffuser 14.

[0043] This application provides an aroma diffuser, as shown in the reference. Figures 1 to 9 The aroma diffuser includes a housing 1, a fan blade 4, a transmission mechanism 2, and a stop 6. The housing 1 includes a first housing 11 and a second housing 12 that rotate relative to each other. The first housing 11 and the second housing 12 are connected to form a receiving cavity 13, which is located inside the housing 1. The receiving cavity 13 includes a fragrance area 131 and an airflow channel 133. The fragrance area 131 is used to contain fragrances. The housing 1 is provided with a fragrance dispersing port 14, and the airflow channel 133 connects the fragrance area 131 and the fragrance dispersing port 14. The fan blade 4 is located in the airflow channel 133. When the fan blade 4 rotates, it can drive the gas flow in the airflow channel 133, thereby promoting the flow of gas in the fragrance area. The flowing gas passes over the surface of the fragrance, carries fragrance molecules to form a fragrant gas, and is discharged from the receiving cavity 13 through the fragrance dispersing port 14, thereby achieving effective diffusion of fragrance.

[0044] The fan blade 4 is connected to the transmission mechanism 2. For example, a shaft 23 is connected to the fan blade 4, and the shaft 23 is fixedly connected to the transmission mechanism 2. When the transmission mechanism 2 rotates, it can drive the fan blade 4 to rotate. The transmission mechanism 2 is connected to the first housing 11 and the second housing 12 respectively. When the first housing 11 moves relative to the second housing 12, it can drive the transmission mechanism 2 to rotate. The stop 6 is located in the receiving cavity 13 and is movably connected to the first housing 11. When the first housing 11 moves, it can drive the stop 6 to move. When the first housing 11 rotates relative to the second housing 12, it can drive the transmission structure and the stop 6 to move simultaneously. The first housing 11 drives the stop 6 to move closer to or away from the fragrance vent 14 to close or open the fragrance vent 14. Figure 1 , Figure 2 As shown, the first housing 11 or the second housing 12 drives the transmission mechanism 2 to rotate, which in turn drives the fan blade 4 to rotate. This allows the user to simultaneously open and close the fragrance vent 14 and drive the fan blade 4 with a single action of driving the relative movement of the first housing 11 and the second housing 12, without the need for separate operations. This reduces the ineffective volatilization of fragrance, lowers the complexity of user operation, and improves the fragrance dispersal efficiency.

[0045] In one implementation, such as Figures 5 to 7 As shown, the transmission mechanism 2 includes an internal gear 21 and a first gear 22. The internal gear 21 is mounted on the first housing 11, and the first gear 22 is rotatably mounted on the second housing 12. The first gear 22 is connected to the fan blade 4 via a shaft 23. The first gear 22 is connected to the internal gear 21 for transmission. Through gear transmission, when the first housing 11 and the second housing 12 rotate relative to each other, the transmission mechanism 2 is driven to rotate, thereby driving the fan blade 4 to rotate. By setting the gear engagement between the internal gear and the first gear 22, when the first housing 11 rotates relative to the second housing 12, the fan blade 4 moves synchronously when the transmission component moves, and the stop 6 moves simultaneously with the fan blade 4. This allows the user to observe the fan blade 4 rotating when opening the fragrance diffuser 14, improving the user experience.

[0046] In another embodiment, the transmission mechanism 2 includes, for example, an internal gear, a rotating shaft, a spring assembly, and an external gear. The internal gear is fixedly mounted on the first housing 11, and both the spring assembly and the external gear are mounted on the rotating shaft. The external gear can mesh with the internal gear. The rotating shaft is engaged on the second housing 12. When the first housing 11 rotates relative to the second housing 12, the internal gear 21 meshes with the external gear, driving the spring to wind and store energy. At this time, the stop 6 moves, for example, moving away from the fragrance vent 14, opening the fragrance vent 14. When the first housing 11 and the second housing 12 stop moving relative to each other, the spring returns to its original state, driving the rotating shaft to rotate, which in turn drives the fan blade 4 to rotate. For example, in another embodiment, the transmission mechanism 2 includes an internal ratchet, a rotating shaft, a pawl, and a torsion spring. The rotating shaft is rotatably mounted on the second housing 12, the fan blade 4 is mounted on the rotating shaft, the internal ratchet is mounted on the first housing 11, the pawl is mounted on the rotating shaft via a pin, and the torsion spring provides continuous pressure to the pawl, causing its tip to press against the internal ratchet. When the first housing 11 rotates relative to the second housing 12, the tooth surface of the internal ratchet pushes the pawl, thereby driving the entire rotating shaft and the fan blade 4 to rotate together. The transmission mechanism 2 is not limited to a single component. By providing the internal tooth portion 21, when the first housing 11 and the second housing 12 rotate relative to each other, the internal tooth portion 21 rotates, thereby driving the first gear 22 to rotate, ultimately achieving the rotation of the fan blade 4. Furthermore, by placing the internal tooth portion 21 on the side wall of the first housing 11, the diameter of the internal tooth portion 21 can be maximized, thereby increasing the number of teeth. This structure facilitates driving the first gear 22 to rotate through more teeth when the first housing 11 rotates only a small angle, thereby improving transmission efficiency and the fan blade 4 speed.

[0047] In one implementation, such as Figures 4 to 8 As shown, the transmission mechanism 2 is located within the receiving cavity 13. The aforementioned internal gear 21 is mounted on the first housing 11 and rotates with the first housing 11. The first gear 22 is connected to the fan blade 4, and when the first gear 22 rotates, it can drive the fan blade 4 to rotate synchronously. The internal gear 21 can be driven to connect with the first gear 22, realizing the transmission of power when the first housing 11 and the second housing 12 rotate relative to each other. The internal gear 21 has a first state of being driven to connect with the first gear 22, and a second state of being disengaged from the first gear 22. When the first housing 11 rotates relative to the second housing 12, the internal gear 21 can drive the first gear 22 away from the internal gear 21. During this process, the internal gear 21 can switch from the first state to the second state.

[0048] The outer casing 1 of the aroma diffuser includes a first casing 11 and a second casing 12, which are connected to each other to form an internal receiving cavity 13. The space within the receiving cavity 13 that communicates with the fragrance area 131 and the fragrance outlet 14 is called an airflow channel 133. A fan blade 4 is disposed within the airflow channel 133, driving the airflow within the airflow channel 133, which in turn drives the airflow within the fragrance area 131, allowing the fragrant gas to flow out of the airflow channel 133. The first casing 11 may include, for example, a cover 111, and the second casing 12 may include, for example, a bottle 121. The bottle 121 has a bottle opening 1211, and the cover 111 is placed over the bottle opening 1211. The internal space of the bottle 121 constitutes the fragrance area 131, and the space inside the cover 111 is the mounting area 132. The fragrance area 131 and the mounting area 132 are connected to form the receiving cavity 13. The fan blade 4, the internal gear 21, and the first gear 22 are all located within the mounting area 132, and the mounting area 132 communicates with the fragrance area 131. The fragrance outlet 14 is located on the cover 111, and the fragrance outlet 14 communicates with both the mounting area 132 and the fragrance area 131. The airflow channel 133 is the communicating space formed by the fragrance outlet and the mounting area 132. In other embodiments, the mounting area 132 may be isolated from the fragrance area 131 by an isolation part. The internal gear 21 and the first gear 22 are located within the mounting area 132, and the fan blade 4 is located within the fragrance area 131. The first gear 22 may have a through-part that passes through the isolation part and connects to the fan blade 4. The fan blade 4 rotates together with the second transmission part. The fragrance outlet 14 may also be located on the second housing 12, and the fan blade 4 is also located within the second housing 12; alternatively, the fragrance outlet 14 may be located on the first housing 11, and the fan blade 4 is located within the second housing 12. The positions of the aroma outlet 14 and the fan blade 4 are not uniquely defined; the space that connects to the aroma outlet 14 and the fragrance area 131 is called the airflow channel 133, and the specific position of the fan blade 4 within the airflow channel 133 is also not uniquely defined.

[0049] When the internal gear 21 is in the first state, and the first housing 11 rotates relative to the second housing 12, the internal gear 21 on the first housing 11 drives the first gear 22 to rotate, and the rotation of the first gear 22 drives the fan blade 4 to rotate. When the first housing 11 rotates relative to the second housing 12 until the internal gear 21 enters the second state, the first gear 22 disengages from the transmission connection with the internal gear 21. Specifically, when the first housing 11 rotates relative to the second housing 12, the internal gear 21 is in transmission connection with the first gear 22. The rotation of the first housing 11 drives the first gear 22 to rotate, providing the first gear 22 with a rotational motion state. When the internal gear 21 enters the second state from the first state, the first gear 22 is released from the restriction of the internal gear 21 and, relying on inertia, can continue to rotate, driving the fan blade 4 to rotate. This achieves the goal that when the first housing 11 and the second housing 12 are relatively stationary, the fan blade 4 continues to rotate, thereby reducing the user's operation time and improving the fragrance dispersal efficiency.

[0050] In one implementation, reference Figure 4 , Figure 5 The first housing 11 includes the aforementioned cover 111 and an annular frame 112 connected to the cover 111. An aroma diffuser 14 is located on the cover 111. The cover 111 includes a top cover 1111 and a peripheral sidewall 1112. The top cover 1111 and the peripheral sidewall 1112 are connected, or the top cover 1111 and the peripheral sidewall 1112 are integrally formed. The top cover 1111 and the peripheral sidewall 1112 enclose an installation area 132. The annular frame 112 is located within the installation area 132 and is fixedly connected to the peripheral sidewall 1112. The cover 111 and the annular frame 112 rotate together, and the aroma diffuser 14 is located on the top cover 1111. An internal toothed portion 21 is connected to the inner side of the annular frame 112 and is located at the bottom of the annular frame 112. The transmission mechanism 2 and the fan blade 4 are located within the space enclosed by the annular frame 112, which facilitates a reasonable allocation of the internal structure of the aroma diffuser, resulting in a compact overall structure and effectively reducing the overall size of the machine. The first gear 22 includes a shaft 23 and a first gear 22. One end of the shaft 23 is connected to the fan blade 4, and the other end is connected to the first gear 22. The first gear 22 is rotatably mounted on the second housing 12 and meshes with the internal gear portion 21. When the internal gear portion 21 rotates, it drives the first gear 22 to rotate, which in turn drives the fan blade 4 to rotate via the shaft 23. In other embodiments, the internal gear portion 21 can be directly disposed on the inner side of the peripheral sidewall 1112, and the transmission mechanism 2 and the fan blade 4 are located on the inner side of the peripheral sidewall 1112. The form of the first housing 11 is not uniquely limited here.

[0051] Furthermore, the aroma diffuser also includes a stop 6 located within the installation area 132. The stop 6 is movably connected to the annular frame 112 and can move inside the annular frame 112. The stop 6 has a sliding protrusion 1121 on the side near the annular frame 112, and the annular frame 112 has a sliding groove 61 on the side near the stop 6. The sliding protrusion 1121 engages with the sliding groove 61 and slides within the sliding groove 61. Alternatively, refer to [reference needed]. Figure 4 , Figure 5 and Figure 9 The baffle 6 has a groove 61 on the side near the annular frame 112, and a sliding protrusion 1121 on the side of the annular frame 112 near the baffle 6. The sliding protrusion 1121 is located in the groove 61 and engages with the groove 61, sliding within the groove 61. When the first housing 11 moves relative to the second housing 12, the annular frame 112 and the cover 111 move together, driving the baffle 6 to move, thereby closing or opening the fragrance diffuser 14. When the baffle 6 is connected to the side wall that forms the fragrance diffuser 14, the baffle 6 blocks the fragrance diffuser 14, and the fragrance diffuser 14 is closed. Users can close the fragrance diffuser 14 when not using the aroma diffuser to prevent fragrance loss. When the baffle 6 is displaced from the side wall that forms the fragrance diffuser 14, the baffle 6 releases its blockage of the fragrance diffuser 14, and the fragrance diffuser 14 is opened, allowing the fragrance to diffuse through the fragrance diffuser 14.

[0052] Specifically, refer to Figure 4 and Figure 9 The inner side of the annular frame 112 is provided with a sliding protrusion 1121. The stop member 6 is provided with a groove 61 that cooperates with the sliding protrusion 1121 on the side near the annular frame 112. The groove 61 is spirally arranged along the circumferential side wall of the stop member 6 and extends along the height direction of the aroma diffuser. The sliding protrusion 1121 is configured to slide within the groove 61. For example, the fragrance outlet 14 is provided at the top of the cover 111. The groove 61 is spirally arranged along the circumferential side wall of the stop member 6 and extends in the direction close to the fragrance outlet 14, so as to drive the stop member 6 to move closer to or away from the fragrance outlet 14. When the cover 111 and the annular frame 112 rotate together relative to the second housing 12, the relative movement of the slide groove 61 and the sliding protrusion 1121 drives the stop 6 to move up and down within the annular frame 112 along the height direction of the aroma diffuser. When the stop 6 rises to the top, it blocks the fragrance vent 14, closing it. When the stop 6 descends until it disengages from the fragrance vent 14, the fragrance vent 14 opens. Simultaneously, the rotation of the first housing 11, through the engagement of the internal gear 21 and the first gear 22, drives the fan blade 4 to rotate. This integrated design allows the user to simultaneously open and close the fragrance vent 14 and drive the fan blade 4 with a single action of rotating the first housing 11, eliminating the need for separate operations. This reduces the ineffective evaporation of fragrance, lowers the complexity of user operation, and improves fragrance dispersal efficiency. The shape of the baffle 6 matches the shape of the fragrance vent 14. For example, when the baffle 6 is at its highest position, it blocks the fragrance vent 14, preventing the fragrance from diffusing. When the baffle 6 moves downward away from the top cover 1111, it shifts away from the top cover 1111, exposing the fragrance vent 14 and allowing the fragrance to be released. In other embodiments, the baffle 6 is located within the receiving cavity 13 and connected to the second housing 12. The fragrance vent 14 is located at a non-central position of the top cover 1111, and the baffle 6 contacts the top cover 1111 and can rotate relative to it. When the first housing 11 rotates relative to the second housing 12, the fragrance vent 14 rotates to face the baffle 6, and the baffle 6 blocks the fragrance vent 14, closing it. When the first housing 11 continues to rotate relative to the second housing 12, the baffle 6 can shift away from the fragrance vent 14, exposing it. The manner in which the baffle 6 moves relative to the fragrance vent 14 is not limited to a single method.

[0053] In one implementation, reference Figure 1As shown in Figure 6, the outer casing 1 also includes a grille 16, which is movably disposed at the fragrance vent 14 and fixedly connected to the second casing 12. The grille 16 is movably disposed relative to the first casing 11. Multiple first through holes 161 are formed on the grille 16, dividing the fragrance vent 14 into multiple spaced-apart first through holes 161; the first through holes 161 communicate with the fragrance area 131. The baffle 6 is provided with multiple baffles 62, each baffle 62 corresponding to one of the multiple first through holes 161. When a baffle 62 is connected to the sidewall corresponding to a first through hole 161, each baffle 62 blocks the corresponding first through hole 161, and the fragrance vent 14 is closed; when a baffle 62 is separated from the sidewall corresponding to a first through hole 161, the fragrance vent 14 is opened. The first through hole 161 is elongated, and there is a connecting strip between two adjacent first through holes 161; a second through hole 621 is formed between two corresponding baffles 62 on the baffle 6, and the second through hole 621 is correspondingly arranged with the connecting strip; when the baffle 62 is connected to the side wall corresponding to the first through hole 161, the connecting strip blocks the second through hole 621; when the baffle 62 is separated from the side wall corresponding to the first through hole 161, the second connecting hole 1226 connects the fragrance dispersing area and the first through hole 161, so as to realize the fragrance dispersing.

[0054] In one embodiment, the transmission mechanism 2 further includes a second gear 24, as shown in the reference. Figure 5 and Figure 7 The first gear 22 is located in the middle of the internal gear section 21. In the first state, the second gear 24 meshes with the first gear 22 and is connected to the internal gear section 21, forming a transmission link. When the first housing 11 rotates, it drives the internal gear section 21 to rotate. The rotation of the internal gear section 21 drives the second gear 24 to rotate, and the rotation of the second gear 24 in turn drives the first gear 22 to rotate, thus realizing the rotation of the fan blade 4. According to the gear transmission principle, with a fixed number of teeth in the internal gear section 21, the fewer the number of teeth and the smaller the diameter of the first gear 22, the more rotations the first gear 22 will make when the first housing 11 rotates by the same angle. Therefore, reducing the size of the first gear 22 allows the user to drive the fan blade 4 to obtain a higher speed with a smaller rotation angle. The fan blade 4 is located inside the annular frame 112 and is set on the central axis of the annular frame 112 through the shaft 23 to ensure that the fan blade 4 is centrally arranged and enhances the gas flow effect. Since the diameter of the first gear 22 is small, it cannot mesh with the internal gear 21 if it is directly set at the central axis. Therefore, the transmission connection and positional adaptation between the internal gear 21 and the first gear 22 are achieved by adding a second gear 24.

[0055] The second housing 12 includes a detachably connected bottle body 121 and a frame 122. The bottle body 121 has a spice zone 131 inside, and a bottle opening 1211 communicating with the spice zone 131 is provided at its top. The frame 122 is installed above or inside the bottle opening 1211 to support the first gear 22. The frame 122 is rotatably connected to the first housing 11, and the frame 122 is fitted around at least a portion of the circumferential outer side of the first housing 11. Specifically, to achieve relative rotation between the frame 122 and the first housing 11, a first annular groove and a first locking part are provided between the frame 122 and the cover 111, which engage with each other. The first annular groove is provided in the frame 122, and the first locking part is provided in the cover 111. A second annular groove and a second locking part are provided between the frame 122 and the annular frame 112, with the second locking part provided in the frame 122 and the second annular groove provided in the annular frame 112. The above-mentioned snap-fit ​​structure enables a reliable connection and relative rotation between the frame 122 and the first housing 11, and allows the frame 122 to move synchronously with the bottle 121.

[0056] The second housing 12 is provided with a travel groove 123, and the second gear 24 is provided with a protrusion 243, such as Figure 7 and Figure 8As shown, the protrusion 243 is connected to the travel groove 123 and can slide within the travel groove 123. The travel groove 123 has a starting end 1231 and an ending end 1232. The process of the protrusion 243 sliding from the starting end 1231 to the ending end 1232 triggers the internal gear 21 to switch from the first state to the second state. Specifically, the frame 122 is provided with a connecting hole 1226, which connects the fragrance area 131 and the fragrance outlet 14. The shaft 23 is rotatably mounted on the frame 122, and the second gear 24 is provided with a protrusion 243, which is connected to the travel groove 123 and can slide within the travel groove 123. A travel groove 123 is provided on the frame 122. The travel groove 123 has a starting end 1231 and an ending end 1232. When the protrusion 243 is located at the starting end 1231, the second gear 24 simultaneously meshes with the internal gear 21 and the first gear 22. The rotation of the internal gear 21 can drive the second gear 24 to rotate. The second gear 24 meshes with the first gear 22. The rotation of the second gear 24 can drive the first gear 22 to rotate. At this time, the rotation of the first housing 11 can drive the first gear 22 and the fan blade 4 to rotate through the internal gear 21 and the second gear 24. When the protrusion 243 is located at the ending end 1232, the internal gear 21 and the first gear 22 are disconnected from the transmission connection. At this time, the second gear 24 is misaligned with the first gear 22, that is, the second gear 24 is disengaged from the first gear 22. For example, when the protrusion 243 is located at the starting end 1231, the user starts to rotate the first housing 11. The internal gear 21 rotates, driving the second gear 24 to rotate. At this time, the second gear 24 meshes with the first gear 22, and the second gear 24 drives the first gear 22 to rotate. When the user continues to rotate the first housing 11, the internal gear 21 continues to drive the second gear 24 to rotate, causing the protrusion 243 to slide from the starting end 1231 to the end end 1232. During this process, the second gear 24 gradually disengages from the first gear 22 until the internal gear 21 and the first gear 22 are disengaged from the transmission connection. At this time, the internal gear 21 enters the second state, and the protrusion 243 moves to the end end 1232. As the protrusion 243 slides from the starting end 1231 to the terminal 1232, it triggers the internal gear 21 to switch from the first state to the second state. The fan blade 4 rotates under the drive of the internal gear 21 until the second gear 24 disengages from the first gear 22. The fan blade 4 continues to rotate under the inertia of the first gear 22, thereby achieving continuous operation of the fan blade 4 with only a small operating torque, improving the fragrance dissipation efficiency and optimizing the user experience.

[0057] In one implementation, reference Figures 1 to 9When the protrusion is located at the starting end 1231, the stop 6 is configured to block the fragrance outlet 14. At this time, the internal gear 21 enters the first state, and the internal gear 21 is connected to the first gear 22. When the protrusion is located at the end 1232, the stop 6 is configured to disengage from the side enclosing the fragrance outlet 14. At this time, the internal gear 21 enters the second state, and the internal gear 21 disengages from the first gear 22. When the fragrance vent 14 is closed, the protrusion is located at the starting end 1231. The user drives the first housing 11 to move relative to the second housing 12. Under the drive of the first housing 11, the stop 6 gradually moves away from the fragrance vent 14, and the fragrance vent 14 gradually opens. At this time, the internal gear 21 is connected to the first gear 22, driving the fan blade 4 to rotate. The protrusion gradually moves from the starting end 1231 to the end end 1232. During the rotation, the internal gear 21 enters a second state, disengaging from the transmission connection with the first gear 22. The first gear 22 enters an idle state, driving the fan blade 4 to rotate continuously until the user stops driving the relative movement between the first housing 11 and the second housing 12. The fan blade 4 continues to rotate. During the process of the user opening the fragrance vent 14, the fan blade 4 rotates until the fragrance vent 14 is fully opened. When the fragrance vent 14 is opened, the protrusion is located at the terminal 1232. The user drives the first housing 11 and the second housing 12 to rotate in the opposite direction, and the stop 6 gradually moves closer to the fragrance vent 14 to close it. During this rotation, the protrusion moves from the terminal 1232 to the starting end 1231. The inner toothed part 21 is initially in the second state, and the fan blade 4 does not rotate until the inner toothed part 21 enters the first state. When the user closes the fragrance vent 14, the fan blade 4 does not rotate, which conforms to the operating rules of the fan blade 4 and improves the user experience.

[0058] In one implementation, reference Figure 5 The second gear 24 includes an upper gear 242 and a lower gear 241 connected to each other. The upper gear 242 and the lower gear 241 are coaxially arranged. The upper gear 242 meshes with the first gear 22, and the lower gear 241 is connected to the internal gear section 21. The number of teeth on the upper gear 242 is greater than the number of teeth on the lower gear 241. According to the gear transmission principle, by setting the number of teeth on the upper gear 242 to be greater than the number of teeth on the lower gear 241, the number of rotations of the first gear 22 can be significantly increased while the internal gear section 21 rotates the same number of times. This transmission structure allows the user to drive the first housing 11 to rotate relative to the second housing 12 by only a small angle. Through the speed-increasing transmission of the internal gear section 21 and the first gear 22, the fan blade 4 can be driven to rotate at a speed much higher than the relative rotation angle and relative rotation speed between the first housing 11 and the second housing 12. Specifically, the number of rotations of the fan blade 4 is much greater than the number of rotations of the first housing 11 relative to the second housing 12, thereby achieving efficient airflow drive and fragrance diffusion.

[0059] In one implementation, reference Figure 5 and Figure 7The transmission mechanism 2 also includes a third gear 25, which is rotatably mounted on the second housing 12. The third gear 25 meshes with the internal gear portion 21 and the second gear 24. Since the second gear 24 uses an upper gear 242 and a lower gear 241 coaxially arranged, and the upper gear 242 has more teeth than the lower gear 241, the pitch circle diameter of the upper gear 242 is larger than that of the lower gear 241 when the module is the same. If the second gear 24 is directly mounted inside the annular frame 112, the large diameter difference can easily lead to the following problems: when the lower gear 241 meshes with the internal gear portion 21, the larger-diameter upper gear 242 may cause structural interference with the annular frame 112; or, if the installation position is adjusted to avoid interference, the lower gear 241 may not be able to mesh normally with the internal gear portion 21, affecting the reliability of the transmission. By adding a third gear 25 as an intermediate transmission wheel, located between the second gear 24 and the internal gear portion 21, the spatial positional relationship between the gears can be effectively coordinated. This design allows the lower gear 241 to have a smaller diameter and the upper gear 242 to have a larger diameter, thereby achieving a larger transmission ratio while ensuring that interference with the annular frame 112 is avoided. With the same number of rotations of the internal gear 21, the output speed and number of rotations of the first gear 22 can be significantly increased, enhancing the driving effect of the fan blades 4.

[0060] In one implementation, such as Figure 7 , Figure 8As shown, the travel groove 123 is arc-shaped, and its concave portion can be oriented towards either the third gear 25 or the first gear 22. When the concave portion faces the third gear 25, the center of the travel groove 123 coincides with the center of the third gear 25; when the concave portion faces the first gear 22, the center of the travel groove 123 coincides with the center of the first gear 22. The travel groove 123 has a starting end 1231 and a ending end 1232, and the axes of the first gear 22 and the third gear 25 are radially distributed along the internal tooth portion 21. In the diametrical direction of the internal tooth portion 21, the distance between the starting end 1231 and the ending end 1232 is d. If the concave portion of the travel groove 123 faces the first gear 22, then the value of d is greater than or equal to the tooth height of the third gear 25. The protrusion 243, for example, protrudes from the surface of the lower gear 241 away from the upper gear 242. When the protrusion 243 is located at the starting end 1231, the internal gear 21 is in the first state. At this time, the third gear 25 meshes with both the lower gear 241 and the internal gear 21, while the upper gear 242 meshes with the first gear 22. When the internal gear 21 rotates, it drives the third gear 25 to rotate, which in turn drives the lower gear 241 to rotate. Simultaneously, it pushes the protrusion 243 to slide along the trajectory of the stroke groove 123 from the starting end 1231 to the ending end 1232, causing the lower gear 241 to gradually move away from the third gear 25. When the distance that the protrusion 243 slides radially along the internal gear 21 exceeds the tooth height of the third gear 25, the lower gear 241 completely disengages from the third gear 25, and the internal gear 21 enters the second state. In another embodiment, the concave portion of the stroke groove 123 faces the third gear 25, and the value of d is greater than or equal to the tooth height of the first gear 22. Similarly, when the internal gear 21 is in the first state, the third gear 25 meshes with the lower gear 241 and the internal gear 21, and the upper gear 242 meshes with the first gear 22. The rotation of the internal gear 21 drives the third gear 25 and the lower gear 241 to rotate, and the protrusion 243 slides along the stroke groove 123, causing the upper gear 242 to gradually move away from the first gear 22. When the radial distance of the protrusion 243 exceeds the tooth height of the first gear 22, the upper gear 242 disengages from the first gear 22, and the internal gear 21 enters the second state.

[0061] In one implementation, reference Figure 4 , Figure 5 , Figure 7 , Figure 8When the first housing 11 rotates clockwise relative to the second housing 12, the internal gear 21 switches from a first state to a second state, that is, the internal gear 21 switches from a state of transmission connection with the first gear 22 to a state of disconnection. The protrusion 243 moves from the starting end 1231 to the ending end 1232. During this process, the first housing 11 rotates relative to the second housing 12, driving the fan blade 4 to rotate, and then the fan blade 4 enters an idling state. When the first housing 11 rotates counterclockwise relative to the second housing 12, the internal gear 21 switches from the second state back to the first state, that is, the internal gear 21 switches from a state of disconnection from the first gear 22 to a state of transmission connection. The protrusion 243 returns from the ending end 1232 to the starting end 1231. During this process, the first housing 11 rotates relative to the second housing 12. Initially, the fan blade 4 does not rotate, but starts rotating after the transmission is reconnected. In this embodiment, the first housing 11 rotates clockwise relative to the second housing 12, driving the stop 6 to descend and gradually open the fragrance vent 14. At this time, the fan blade 4 rotates, which the user can immediately observe, and the fragrance is well diffused. The first housing 11 rotates counterclockwise relative to the second housing 12, driving the stop 6 to ascend and gradually close the fragrance vent 14. The state where the fan blade 4 does not rotate corresponds to the closing operation of the fragrance vent 14, improving the intuitiveness of the operation and the overall user experience.

[0062] In one implementation, such as Figure 5As shown, a mounting groove 1223 is formed on the side of the frame 122 away from the fragrance area 131. The frame 122 has an upper sidewall 1224 and a lower sidewall 1225 corresponding to the mounting groove 1223, arranged opposite each other along the height direction of the diffuser. The second gear 24 is located within the mounting groove 1223, and protrusions 243 are provided at both ends of the second gear 24 along the height direction of the diffuser. The upper sidewall 1224 and the lower sidewall 1225 are respectively provided with stroke grooves 123, with the two protrusions 243 corresponding one-to-one with the two stroke grooves 123. Specifically, the frame 122 includes a base frame 1221 and an upper frame 1222. The base frame 1221 is detachably connected to the bottle body 121. The base frame 1221 is disposed within the bottle opening 1211, and a connecting hole 1226 is provided on the base frame 1221 for connecting the fragrance chamber and the fragrance outlet 14. The base frame 1221 is rotatably connected to the first housing 11. The upper frame 1222 is located on the side of the base frame 1221 away from the fragrance area 131. The upper frame 1222 is situated in the middle area of ​​the bottle opening 1211 and forms a mounting groove 1223 with the base frame 1221, having an upper sidewall 1224 and a lower sidewall 1225. The upper sidewall 1224 and lower sidewall 1225 are positioned opposite each other along the height direction of the diffuser. The first gear 22, the second gear 24, and the third gear 25 are all accommodated within the mounting groove 1223. The upper sidewall 1224 and lower sidewall 1225 are each provided with a stroke groove 123, which are positioned opposite each other along the height direction of the diffuser and are identical in shape and size. The upper gear 242 away from the lower gear, and the lower gear 241 away from the upper gear 242, both have protrusions 243. These protrusions 243 correspond one-to-one with the two stroke grooves 123, ensuring the stability of the second gear 24 during sliding and preventing structural instability. Similarly, the third gear 25 is also provided with a protrusion. The upper sidewall 1224 and the lower sidewall 1225 are provided with holes that mate with the protrusion. The protrusion is engaged in the holes, allowing the third gear 25 to rotate relative to the frame 122 while restricting its vertical and horizontal movement. The first gear 22 and the fan blade 4 are connected by a shaft 23. The first gear 22 is located in the mounting groove 1223, and the fan blade 4 is located outside the mounting groove 1223. The upper sidewall 1224 is provided with an opening, through which the shaft 23 passes and is fixedly connected to the fan blade 4.

[0063] To further improve transmission efficiency, the aroma diffuser also includes a bearing 5. The second housing 12 has a bearing 5 fixing position, and the outer ring 51 of the bearing 5 is fixedly connected to the bearing 5 fixing position. The inner ring 52 of the bearing 5 is sleeved on the shaft 23 and fixedly connected to the shaft 23. Specifically, the bearing 5 fixing position is the aforementioned opening, the outer ring 51 of the bearing 5 is fixed at the opening, and the inner ring 52 of the bearing 5 is sleeved on the outer wall of the shaft 23 and rotates together with the shaft 23. By setting the bearing 5, the rotational resistance of the shaft 23 can be significantly reduced, improving the rotational efficiency of the fan blade 4. Since the upper gear 242 meshes with the first gear 22, and the first gear 22 is located at the bottom end of the shaft 23, the upper gear 242 needs to be spaced apart from the shaft 23 to prevent friction between the upper gear 242 and the shaft 23 from affecting the rotation of the shaft 23.

[0064] In one implementation, such as Figures 4 to 6 As shown, the fan blade 4 includes a hub 41 and blades 42 connected to each other, and a counterweight 7 is provided on the hub 41. Specifically, the hub 41 has a groove on the side away from the shaft 23, and multiple counterweights 7 are provided in the groove. When the internal gear 21 switches from the first state to the second state, the fan blade 4 achieves idling under the action of inertia. The counterweights 7 can increase the moment of inertia, thereby extending the idling time and the number of revolutions.

[0065] In one embodiment, see specific reference. Figure 7 The first housing 11 has two first interference portions 113 on one side of the receiving cavity 13. The two first interference portions 113 protrude from the first housing 11 and are located on opposite sides of the aroma diffuser in the radial direction. The second housing 12 has a second interference portion 124 located between the two first interference portions 113. When the first interference portions 113 and the second interference portions 124 come into contact, they prevent relative rotation of the first housing 11 and the second housing 12. By setting two first interference portions 113 that are radially opposite to each other along the aroma diffuser and the second interference portion 124 located between the two first interference portions 113, the contact between the first interference portions 113 and the second interference portion 124 forms interference, preventing relative movement of the first housing 11 and the second housing 12. This provides a labor-saving reminder to the user and prevents the user from continuously rotating the first housing 11 and the second housing 12, which would make operation cumbersome and laborious.

[0066] Furthermore, when one of the two first interference parts 113 contacts the second interference part 124, the baffle 6 blocks the fragrance outlet 14; when the other of the two first interference parts 113 contacts the first interference part 113, the baffle 6 is offset from the fragrance outlet 14. The portion of the slide groove 61 corresponding to half of the inner side of the annular frame 112 has a height in the height direction of the aroma diffuser equal to the stroke of the baffle 6 from the bottom to the top, and the baffle 62 just blocks the fragrance outlet 14.

[0067] The above description is merely a preferred embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
