[0002] As people's living standards improve, more and more people are paying attention to the quality of life and have higher and higher requirements for air comfort. Fragrance devices are commonly used in air conditioners to regulate the air and improve user comfort. However, existing fragrance devices cannot automatically control their on / off state. When users do not need the fragrance function, they cannot turn off the device, or the process of turning it off is cumbersome, affecting the user experience. In other words, existing fragrance devices have a problem with automatic on / off operation. Summary of the Invention

[0016] In one alternative embodiment, a first seal is affixed to the first side plate, and a second seal is affixed to the second side plate.

[0017] In one alternative embodiment, the fan includes a centrifugal impeller and a fan motor, the centrifugal impeller and the fan motor being connected.

[0043] As people's living standards improve, more and more people are paying attention to the quality of life and have higher and higher requirements for air comfort. However, dust accumulated in air conditioner filters can easily produce odors, or there may be odor problems in the environment itself, or users may have a need for a scented indoor environment. Therefore, we often use fragrance devices installed in air conditioners to release scented airflow to overcome the aforementioned air odor problems, or to improve comfort and meet user needs. However, in the existing technology, the process of turning off the fragrance device when the odor in the air is eliminated, or when the user does not need the fragrance function, is relatively complicated and cannot be turned off in a timely manner. When the fragrance function is needed, it is also difficult to turn on the fragrance device in a timely manner, resulting in a slow release of fragrance. Alternatively, there is a device in the existing technology that uses a solenoid valve to switch the fragrance device; however, the structure of the solenoid valve is complex and the manufacturing cost is high. Using a solenoid valve to switch the fragrance device easily leads to problems such as a high damage rate, high maintenance difficulty, high cost, and large size of the fragrance device. Furthermore, other methods of switching on / off the fragrance device in the prior art also suffer from this drawback to varying degrees. In summary, the fragrance device in the prior art suffers from the problem of having a relatively complex start-up and shutdown procedure.

[0044] Please see Figure 1 , Figure 3 , Figure 4 , Figure 5 The present invention provides a fragrance device 10, which includes a housing 11, a fan, and a switching device. The housing 11 is provided with an air inlet 11a and an air outlet 11b, and the fragrance tank 12 is provided inside the housing 11. The fragrance tank 12 is used to communicate with the air inlet 11a and the air outlet 11b. The fan is disposed inside the housing 11 and is used to draw external airflow into the housing 11 through the air inlet 11a, pass through the fragrance tank 12, and flow out through the air outlet 11b. The switching device is installed on the housing 11 and includes a shielding member 131 and a driving assembly. The driving assembly is used to drive the shielding member 131 to connect the fragrance tank 12, the air inlet 11a, and the air outlet 11b. The driving assembly is also used to drive the shielding member 131 to isolate the fragrance tank 12 from the air inlet 11a and / or the air outlet 11b.

[0045] Specifically, in the fragrance device 10, external airflow is drawn in by the fan and enters the housing 11 through the air inlet 11a. After passing through the fragrance tank 12, it becomes fragrant due to the solid fragrance within the tank, and the fragrant airflow exits the housing 11 through the air outlet 11b. This serves to increase the fragrance of the environment or eliminate odors. When the fragrance in the area is too strong or the user does not need the fragrance, the airflow entering the housing 11 through the air inlet 11a does not need to pass through the fragrance tank 12 and exits directly through the air outlet 11b. Specifically, this application proposes several solutions to prevent airflow from passing through the fragrance tank 12. First, the fragrance tank 12 is isolated from the air inlet 11a. In this case, the gas flowing in from the air inlet 11a cannot enter the fragrance tank 12. Second, the fragrance tank 12 is isolated from the air outlet 11b. In this case, external airflow cannot flow from the fragrance tank into the air outlet 11b, thereby releasing the fragrant airflow. Thirdly, the fragrance tank 12 is isolated from both the air inlet 11a and the air outlet 11b. This is a preferred solution, as it best isolates the aroma and prevents airflow from passing through the fragrance tank 12. The fragrance tank 12 is completely isolated from the outside world, making it difficult for airflow to enter from any direction. However, isolating the fragrance tank 12 from the air inlet 11a or the air outlet 11b may result in some airflow flowing into the fragrance tank 12 from the air outlet 11b and the air inlet 11a. While some external airflow will still enter the fragrance tank 12 through the air inlet 11a, this portion is relatively small compared to the total airflow passing through the fragrance device 10. The airflow passing through the fragrance tank 12 carries aroma primarily because it carries fragrance compound molecules as it passes through the fragrance within the tank, causing these molecules to diffuse in the air and impart aroma. If only a small portion of the airflow enters the fragrance tank 12, the total amount of aroma molecules it carries after merging with the rest of the airflow is relatively small. Furthermore, due to the diffusion of aroma molecules in the air—that is, their random movement—the final concentration of aroma molecules in the air is negligible and has almost no impact on the odor in the air. Therefore, besides isolating the fragrance tank 12 from both the air inlet 11a and the air outlet 11b—which is a better solution for shutting down the fragrance device 10—isolieving the fragrance tank 12 from the air inlet 11a and from the air outlet 11b also achieves the effect of shutting down the fragrance device 10.

[0046] This application proposes three methods to prevent airflow from passing through the fragrance tank 12: isolating the fragrance tank 12 from the air inlet 11a; isolating the fragrance tank 12 from the air outlet 11b; and isolating the fragrance tank 12 from both the air inlet 11a and the air outlet 11b. All three methods effectively block airflow from passing through the fragrance tank 12. Among these, the method of using a drive assembly to move the blocking member 131 to isolate the fragrance tank 12 from both the air inlet 11a and the air outlet 11b is a particularly effective embodiment. Furthermore, when it is necessary to eliminate odors, or when the fragrance in the area is perceived to be too weak and the fragrance tank 12 needs to be reopened, the drive assembly can also be used to open the fragrance tank 12 to the air inlet 11a and the air outlet 11b, allowing external airflow to pass through the fragrance tank 12 again and release the fragrance.

[0047] Please see Figures 2 to 5 In an optional embodiment, the bottom of the spice trough 12 is provided with a first air hole 12a and a second air hole 12b, wherein the first air hole 12a is connected to the air inlet 11a and the second air hole 12b is connected to the air outlet 11b. When the spice trough 12, the air inlet 11a and the air outlet 11b are connected, the shielding member 131 opens the first air hole 12a and the second air hole 12b. When the spice trough 12 is isolated from the air inlet 11a and / or the air outlet 11b, the first air hole 12a and / or the second air hole 12b are blocked.

[0048] Thus, the external airflow entering through the air inlet 11a enters the fragrance tank 12 through the first air hole 12a and then flows out of the fragrance tank 12 through the second air hole 12b. In an optional embodiment, the fragrance tank 12 is provided with multiple first air holes 12a and multiple second air holes 12b, and the multiple first air holes 12a and multiple second air holes 12b are arranged in an array, or matrix, meaning a rectangular array, arranged side by side in an array form. This arrangement makes the fragrance tank easy to process, and at the same time, it facilitates sufficient airflow exchange, so that the airflow passing through the fragrance tank 12 carries sufficient aroma to meet the user's needs. When the fragrance tank 12 and / or the air outlet 11b are isolated, the shielding member 131 can block all the first air holes 12a, or all the second air holes 12b, or all the first air holes 12a and the second air holes 12b. This prevents the airflow from passing smoothly through the fragrance tank 12, achieving the effect of shutting off the fragrance device 10. The solution of the shielding member 131 shielding all the first vents 12a and the second vents 12b is more effective, and has better sealing when the fragrance device 10 needs to be closed.

[0049] Please see Figures 3 to 5In an optional embodiment, the driving component is used to drive the blocking member 131 away from the spice tank 12, so that the air inlet 11a, the first air hole 12a, the second air hole 12b, and the air outlet 11b are connected; the driving component is also used to drive the blocking member 131 closer to the spice tank 12, so that the blocking member 131 blocks the first air hole 12a and / or the second air hole 12b. Specifically, the spice tank 12 has an open state and a closed state. When it is in the open state, the first air hole 12a and the second air hole 12b are open, and when it is in the closed state, the first air hole 12a and / or the second air hole 12b are blocked. Therefore, the blocking member 131 controls the opening or closing of the spice tank 12 by moving away from and closer to the first air hole 12a and / or the second air hole 12b. At this time, the blocking member 131 also has corresponding close-up and away-up positions. After the drive assembly moves the shielding member 131 to a distant position and opens the fragrance slot 12, the drive assembly needs to continuously drive the shielding member 131 to maintain it away from the first vent 12a and the second vent 12b, since the fragrance device 10 needs to continuously emit fragrance. Therefore, when the fragrance is too strong or the user does not need the fragrance, the drive assembly drives the shielding member 131 from the distant position back to the near position until the fragrance slot 12 is closed again. Furthermore, this configuration allows the fragrance slot 12 to be opened and closed by the movement of the shielding member 131. In addition to moving closer and further away, the shielding member 131 can also open or close the fragrance slot 12 through various other movements, such as sliding and rotating.

[0050] Please see Figures 3 to 5 In an optional embodiment, the first vent 12a and the second vent 12b are disposed at the bottom of the fragrance tank 12, while the shielding member 131 is disposed below the fragrance tank 12. A driving member drives the shielding member 131 to move up and down to move closer to or further away from the fragrance tank 12. This arrangement facilitates the layout of the various structures within the fragrance device 10, effectively reducing the cross-sectional area of ​​the fragrance device 10, and making it more suitable for installation in other devices. In an optional embodiment, the fragrance device 10 is installed in the duct of an air conditioner, air purifier, or other household appliances that can blow air.

[0051] Please refer to the following: Figure 2In an optional embodiment, the fragrance device 10 includes a plurality of fragrance slots 12 and a plurality of shielding members 131. The shielding members 131 and the fragrance slots 12 are arranged in a one-to-one correspondence. Specifically, each of the plurality of fragrance slots 12 has a relatively independent receiving cavity, and each receiving cavity can hold different types and scents of fragrances. It is worth noting that each fragrance slot 12 is correspondingly provided with one shielding member 131. During the use of the fragrance device 10, the user can select a fragrance slot 12 and control the opening and closing of that fragrance slot 12 individually by controlling the shielding member 131 corresponding to that selected fragrance slot 12. At this time, the shielding members 131 corresponding to the other fragrance slots 12 block the first vent 12a and / or the second vent 12b of their respective fragrance slots 12, so that the other fragrance slots 12 are in a normally closed state, without affecting the fragrance slots 12 in use. Furthermore, the shielding member 131 and the fragrance slot 12 are configured in a one-to-one correspondence, so that each fragrance slot 12 can be independently controlled to open and close. This allows the user to turn one of the fragrance slots 12 on or off individually as needed, and select their preferred fragrance type.

[0052] Please see Figure 2 Furthermore, the number of the fragrance slots 12 is not less than 2 and not more than 10. Given that the fragrance device 10 includes multiple fragrance slots 12, the number of fragrance slots 12 is controlled between 2 and 10, which allows for providing users with a variety of fragrance options. This simplifies the structure of the fragrance device 10 and reduces manufacturing costs.

[0053] Please see Figure 6In one optional embodiment, the drive assembly selectively drives one of the blocking members 131 to move, thereby connecting the fragrance tank 12, the air inlet 11a, and the air outlet 11b. This simplifies the structure of the fragrance device 10 and reduces manufacturing costs. In another optional embodiment, the drive assembly uses a drive motor 142 to drive the blocking member 131 away from the fragrance tank 12, thereby connecting the air inlet 11a, the air outlet 11b, and the fragrance tank 12. The drive assembly selectively drives one of the fragrance tanks 12 to open. Therefore, only one drive motor 142 is needed within the fragrance device 10, effectively reducing the size and manufacturing cost of the fragrance device 10. The same applies to other components that control the blocking member 131 away from the fragrance tank 12, besides the drive motor 142. In another embodiment, the drive assembly may also selectively drive multiple blocking members 131 to move, thereby opening multiple fragrance tanks 12 in the fragrance device to obtain the desired mixed fragrance. However, such a setup requires a complex drive component structure, which can easily lead to problems such as high manufacturing costs and large size of the fragrance device. Furthermore, users rarely require mixed fragrances, as this is a relatively uncommon requirement. That is, if multiple blocking elements 131 are driven separately, then most of the time only one blocking element 131 will be switched on, while the others will remain idle, resulting in waste. Therefore, the preferred solution is to selectively drive one of the blocking elements 131 to move, thereby opening the fragrance slot 12 corresponding to that blocking element 131, while keeping the other fragrance slots 12 normally closed. Please refer to [link to relevant documentation]. Figure 3 , Figure 3 This is a cross-sectional view of one of the fragrance tanks 12 of the fragrance device 10 when it is in the open state. It can be seen that when one of the fragrance tanks 12 is open, the other fragrance tanks 12 are in the normally closed state.

[0054] Please see Figure 6 , Figure 9In an optional embodiment, the drive assembly includes a drive motor 142 and a cam disk 141. The cam disk 141 and the drive motor 142 are connected. When the drive motor 142 rotates, the cam disk 141 periodically drives one of the blocking members 131 to move away from the spice trough 12. The cam disk 141 and the drive motor 142 are used to drive the blocking member 131 away from the spice trough 12. Specifically, the drive motor 142 drives the cam disk 141 to rotate. A contact portion 141a is provided on the cam disk 141. The contact portion 141a moves with the rotation of the cam disk 141. When the contact portion 141a approaches one of the blocking members 131, it drives the blocking member 131 away from the spice trough 12 corresponding to that blocking member 131. When the contact portion 141a disengages from the blocking member 131, the blocking member 131 is no longer driven, and the blocking member 131 is driven by the rest of the drive assembly, returning to its initial closed position.

[0055] Furthermore, the movement trajectory of the contact portion 141a is the circumferential trajectory of the cam disk 141. The multiple spice slots 12 are arranged in a ring. When the cam disk 141 rotates, the contact portion 141a can contact different blocking members 131, selectively driving the blocking member 131 away from the spice slot 12. When the cam disk 141 rotates one or several times, the contact portion 141a moves to the same position, periodically driving the blocking member 131 corresponding to that position away from the spice slot 12. When it is necessary to change the spice slot 12 that needs to be opened, the drive motor 142 drives the cam disk 141 to rotate, causing the contact portion 141a to move to the area corresponding to the desired spice slot 12 and move within that area, thus moving the blocking member 131 away from or closer to the spice slot 12. The cam disk 141 is a disc-shaped cam with a radial profile dimension that varies and rotates about its axis. When it rotates about a fixed axis, it can push a follower to move in a plane perpendicular to the cam axis. It is the most basic type of cam, with a simple structure and the widest application. In this application, the cam disk 141 is used to convert the rotation of the drive motor 142 into up-and-down motion, thereby driving the blocking member 131 to move closer to or away from the spice trough 12.

[0056] Please see Figure 10In an optional embodiment, the housing 11 includes a cover 111 and a body 112. An air inlet 11a is formed on the cover 111, and an air outlet 11b is formed on the body 112. Since the plurality of spice trays 12 are arranged in a ring, the body 112 also has a plurality of air outlets 11b, which correspond one-to-one with the plurality of spice trays 12. Optionally, to improve air quality, a grille structure or filter is provided between the ring-shaped spice trays 12. This grille structure or filter corresponds to the air inlet 11a. The airflow entering through the air inlet 11a passes through the grille structure or filter, then through the spice trays 12, and finally exits through the air outlet 11b.

[0057] Please see Figure 9 In one optional embodiment, the cam disk 141 is disposed inside the housing 11, and the drive motor 142 is disposed outside the housing 11. The housing 112 is provided with a connection hole for connecting the cam disk 141 and the drive motor 142. This placement of the drive motor 142 outside the housing 11 effectively reduces the volume of the housing 11 and also reduces the limitations on the volume of the drive motor 142. Furthermore, this arrangement separates the manufacturing of the housing 11 and its internal components from the manufacturing of the drive motor 142, effectively reducing costs. The internal structure of the fragrance device 10 is also simplified, facilitating maintenance. In another optional embodiment, the fragrance device 10 is installed inside an air conditioner. The indoor unit 100 of the air conditioner has a control component connected to the drive motor 142, thereby controlling the switching device to open or close the fragrance device 10. The drive motor 142 being disposed outside the housing 11 makes it easy to connect the drive device to the control component of the indoor unit 100 of the air conditioner, thereby realizing the intelligent switching of the fragrance device 10.

[0058] Please see Figure 6 , Figure 8In an optional embodiment, the driving assembly further includes an elastic element 132 and a fixed base 133. The fixed base 133 is fixedly connected to the housing 11, and the elastic element 132 connects the fixed base 133 and the blocking element 131. The elastic element 132 has an initial position and a deformed position. When the contact portion 141a contacts the blocking element 131, driving the blocking element 131 away from the spice tank 12 and maintaining the blocking element 131 in this position, the elastic element 132 moves to the deformed position, that is, the elastic element 132 deforms and stores energy, and the contact portion 141a needs to overcome the elastic force of the elastic element 132 at this time. When the contact portion 141a disengages from the blocking element 131, the elastic element 132 resets, that is, returns from the deformed position to the initial position, so as to drive the blocking element 131 closer to the spice tank 12. Further, the elastic element 132 is disposed below the blocking element 131. When the spice trough 12 is open, the elastic element 132 is compressed and moves to its deformed position. When the contact portion 141a is not in contact with the blocking member 131, the elastic force of the elastic element 132 provides support to the blocking member 131, thereby maintaining the blocking member 131's obstruction of the first air hole 12a and / or the second air hole 12b. When the spice trough 12 is open, the blocking member 131 is in the downward open position, at which point the elastic element 132 undergoes elastic deformation due to compression, generating an upward elastic force. However, at this time, the contact portion 141a of the cam disk 141 is in contact with the elastic element 132; that is, when the spice trough 12 is open, the contact portion 141a needs to overcome the elastic force generated by the elastic element 132. When it is necessary to close the spice trough 12, simply control the contact part 141a to disengage from the blocking member 131. The elastic force generated by the pressure on the elastic member 132 can drive the blocking member 131 to move, so that the blocking member 131 re-blocks the first air hole 12a and / or the second air hole 12b. In an optional embodiment, the elastic member 132 is a spring. The spring is a low-cost, easy-to-replace, and easy-to-maintain elastic member 132. In addition, the spring is fixedly connected to the housing 11 by the fixing seat 133. The setting of the fixing seat 133 helps to simplify the structure of the spice device 10 and reduce the installation difficulty of the spice device 10. During installation, it is not necessary to fix the elastic member 132 corresponding to each spice trough 12 to the housing 11 one by one. Instead, the blocking member 131 and the elastic member 132 can be pre-produced separately and then simply assembled. With this setting, the internal layout of the spice device 10 is more compact.

[0059] Please see Figure 6 , Figure 8In an optional embodiment, the fragrance device 10 includes a plurality of elastic members 132, wherein each elastic member 132 is correspondingly arranged with a blocking member 131. Furthermore, each elastic member 132 is correspondingly provided with a fixing seat 133. This arrangement ensures that when one of the fragrance slots 12 is opened, the remaining elastic members 132 keep the other unused fragrance slots 12 closed, preventing fragrance leakage. This one-to-one correspondence effectively guarantees the independence of each fragrance slot 12. When the fragrance slot 12 is not needed, it can be stably maintained in a closed state.

[0060] Please see Figure 4 , Figure 5 In an optional embodiment, the bottom of the spice trough 12 is provided with a first partition 123, which divides the housing 11 into a first cavity and a second cavity. The first cavity connects the air inlet 11a and the first vent 12a, and the second cavity connects the air outlet 11b and the second vent 12b. The first partition 123 is used to block the first cavity and the second cavity, preventing them from being directly connected, thus avoiding direct connection between the air inlet 11a and the air outlet 11b. When the spice trough 12 is open, the first partition 123 prevents some airflow from flowing in from the air inlet 11a from bypassing the spice trough 12 and flowing directly out from the air outlet 11b, thus preventing a good aroma-enhancing effect.

[0061] Please see Figure 4 In an optional embodiment, the shielding member 131 is provided with a recess 131c for avoiding the first partition 123. When the shielding member 131 approaches or moves away from the spice tank 12, the first partition 123 is at least partially located in the recess 131c. The recess 131c is used to avoid the first partition 123, preventing the arrangement of the first partition 123 from affecting the opening and closing of the spice tank 12. Furthermore, since the shielding member 131 is movably installed within the housing 11, the arrangement of the recess 131c ensures that the first partition 123 is at least partially located in the recess 131c during the movement of the shielding member 131, so that the first partition 123 always isolates the first cavity and the second cavity during the movement of the shielding member 131. Specifically, when the shielding member 131 approaches or moves away from the first partition 123, the first partition 123 also moves up and down within the clearance groove 131c, but never leaves the clearance groove 131c.

[0062] Please see Figure 3 , Figure 4 , Figure 5In an optional embodiment, the spice trough 12 includes a first base plate 121 and a second base plate 122. A first vent 12a is disposed on the first base plate 121, and a second vent 12b is disposed on the second base plate 122. The first base plate 121 and the second base plate 122 are arranged at an angle, and a first partition 123 is located at the connection between the first base plate 121 and the second base plate 122. When it is necessary to close the spice trough 12, the shielding member 131 isolates the spice trough 12 from the air inlet 11a and the air outlet 11b, which is a solution with good isolation effect. It can effectively prevent the leakage of fragrance. The first vent 12a and the second vent 12b are respectively disposed on the first base plate 121 and the second base plate 122. Airflow flows in through the first vent 12a of the first base plate 121, passes through the spice trough 12, and flows out through the second vent 12b on the second base plate 122. The first base plate 121 and the second base plate 122 are arranged at an angle to facilitate smooth airflow through the fragrance tank 12. Furthermore, the angle formed between the first base plate 121 and the second base plate 122 can be an acute angle, a right angle, or an obtuse angle, as long as the airflow can smoothly enter the fragrance tank 12 from the first air hole 12a. In one embodiment, the angle between the first base plate 121 and the second base plate 122 is not less than 90 degrees and not greater than 180 degrees. This arrangement can maximize the residence time of the airflow in the fragrance tank 12, thereby allowing the airflow exiting from the air outlet 11b to carry more aroma molecules, thus giving the fragrance device 10 a better aroma-enhancing effect.

[0063] Please see Figure 3 ,、 Figure 4 , Figure 8 In an optional embodiment, the shielding member 131 includes a first side plate 131a and a second side plate 131b. The first side plate 131a is used to shield the first air hole 12a, and the second side plate 131b is used to shield the second air hole 12b. The clearance groove 131c is disposed between the first side plate 131a and the second side plate 131b.

[0064] The blocking member 131 includes a blocking portion and a connecting plate 131d connected to each other. The blocking portion includes a first side plate 131a, a second side plate 131b, and a recessed groove 131c. The first side plate 131a and the second side plate 131b are arranged at an angle. The driving assembly includes an elastic element 132 and a cam disk 141. The side of the connecting plate 131d near the blocking portion is used to contact the cam disk 141, and the side of the connecting plate 131d away from the blocking portion is connected to the elastic element 132. Furthermore, the first side plate 131a and the second side plate 131b can form an angle consistent with the first base plate 121 and the second base plate 122. This allows the first base plate 121 and the second base plate 122 to better fit with the first side plate 131a and the second side plate 131b when the spice trough 12 is closed, thus achieving a better blocking effect.

[0065] Please see Figure 8 In one optional embodiment, a first sealing element 134a is attached to the first side plate 131a, and a second sealing element 134b is attached to the second side plate 131b. Specifically, the first sealing element 134a and the second sealing element 134b are used to seal the first vent 12a and the second vent 12b, respectively. This provides better shielding effect for the first side plate 131a and the second side plate 131b, preventing aroma leakage. The first sealing element 134a and the second sealing element 134b can be flexible. In one optional embodiment, the first sealing element 134a and the second sealing element 134b are made of silicone.

[0066] Please see Figure 6 , Figure 7 In one optional embodiment, the fan includes a centrifugal impeller 151 and an impeller motor 152, with the centrifugal impeller 151 connected to the motor. A centrifugal impeller is a relatively reliable and stable device for generating negative pressure and drawing in airflow. Specifically, the centrifugal impeller operates on the principle of converting kinetic energy into potential energy, using a high-speed rotating impeller to accelerate the gas, then decelerate and change its flow direction, thus converting kinetic energy into potential energy (pressure). The motor is a commonly used drive component. This configuration significantly reduces the manufacturing cost of the fragrance device 10 and facilitates its maintenance.

[0067] Please see Figure 6In an optional embodiment, the fragrance device 10 further includes a base 16 disposed between the centrifugal impeller 151 and the impeller motor 152. The base 16 serves to isolate the centrifugal impeller 151 and the impeller motor 152. This is because the impeller motor 152 operates more vigorously. Placing the impeller motor 152 and the centrifugal impeller 151 on the same side of the base 16 may affect the opening and closing of the fragrance box 12. Further, the fragrance box 12, the shielding member 131, and the centrifugal impeller 151 are disposed on the same side of the base 16, while the impeller motor 152 is disposed on the other side of the base 16. Besides the fan composed of the centrifugal impeller 151 and the impeller motor 152, the fragrance device 10 can also employ various other types of fans, such as axial flow fans. The goal is simply to redirect the airflow flowing from the air inlet 11a into the housing 11, directing it through the fragrance box 12 and the air outlet 11b.

[0068] Please see Figure 6 In an optional embodiment, the base 16 is provided with a plurality of second partitions 161, and an mounting position for mounting the shielding member 131 is provided between two adjacent second partitions 161. The second partitions 161 further ensure the independence of each shielding member 131 and each fragrance tank 12, so that the opening and closing of one fragrance tank 12 will not affect the other fragrance tanks 12, thereby preventing the leakage of fragrance.

[0069] Please refer to Figure 11 This invention also proposes an indoor air conditioning unit 100, which includes the aforementioned fragrance device 10. Specifically, the fragrance device 10 is configured to emit fragrance into the room according to the user's needs, thereby increasing the indoor aroma and enhancing user pleasure or eliminating odors. Furthermore, the fragrance device 10 is equipped with a switching device. When the fragrance in a certain area is perceived to be too strong, or when the fragrance function of the unit 20 is not needed, the switching device can be controlled to shut down the fragrance device 10, causing the indoor air conditioning unit 100 to stop emitting fragrance, thus improving the user experience. In addition, the fragrance device 10, due to its built-in centrifugal impeller 151 and impeller motor 152, can also be used independently in certain situations to increase the indoor aroma. In an optional embodiment, an air duct is formed inside the indoor air conditioning unit 100, with an air inlet and an air outlet at each end. The air outlet of the fragrance device 10 is connected to the air duct, so that the airflow blown out of the air duct by the unit carries fragrance. To ensure a more even and rapid diffusion of the aroma, the fragrance device 10 may also include a heating module or a stirring device. Specifically, the air conditioner indoor unit 100 includes a floor-standing air conditioner indoor unit.

[0070] Please see Figure 11 , Figure 12 In one optional embodiment, the air conditioner indoor unit 100 includes a main unit 30 and a sub-unit 20. The main unit 30 has an indoor heat exchange module. The specific structure of the heat exchange module of the main unit 30 can refer to the existing technology of air conditioner indoor unit 100, especially floor-standing air conditioner indoor unit 100. The sub-unit 20 has an air outlet function to achieve the effect of blowing and regulating indoor air. Furthermore, the sub-unit 20 can be detachably connected to the main unit 30. This allows the sub-units 20 to regulate indoor air in a way that is either interconnected or independent, ensuring that the heat exchange effect of the indoor heat exchange module is not affected when the sub-units 20 are connected to or disconnected from the main unit 30. This ensures the heat exchange stability of the air conditioner indoor unit 100. The fragrance device 10 is disposed in the sub-unit 20 and is used to emit fragrance into the room. In one optional embodiment, the fragrance device 10 can be installed in the air duct of the air conditioner indoor unit 100. In this way, the fragrance device 10 is used to emit fragrance into the room to increase the aroma of the indoor environment and eliminate odors. It is understandable that the sub-machine 20 can emit fragrance in different areas according to the user's needs.

[0071] Specifically, the main unit 30 is provided with a receiving cavity for accommodating the sub-unit 20. The sub-unit 20 has two states: contained within the receiving cavity and detached from the receiving cavity. Optionally, the specific connection structure between the sub-unit 20 and the main unit 30 can be snap-fit, magnetically attached, connected, or plugged in. In an optional embodiment, when the sub-unit is in a non-working state, the sub-unit 20 is completely contained within the receiving cavity. Of course, the sub-unit 20 can also be partially located within the receiving cavity and partially located outside the receiving cavity, i.e., partially exposed outside the main unit 30. In one embodiment, the sub-unit 20 is mounted on the lower part of the main unit 30, and the sub-unit 20 is provided with a moving component. Optionally, the moving component is a caster wheel. When the sub-unit 20 is detached from the main unit 30, the sub-unit 20 moves relative to the main unit 30 within the room to meet the air conditioning needs of different areas of the room. For example, in areas with many people, or in areas that need fragrance or have odors, it can meet the point-to-point air supply requirements of a certain area, thereby achieving long-distance point-to-point and directional air supply, and thus improving the air treatment effect.

[0072] This application also proposes an air conditioner that includes the indoor unit described above. Furthermore, the specific structure of the indoor unit is as described in the embodiments above. Since this air conditioner adopts all the technical solutions of all the embodiments described above, it at least possesses the beneficial effects brought about by the technical solutions of the above embodiments.

[0073] The above description is merely an optional embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
