[0044] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0045] In the prior art, only one type of fragrance component can usually be installed on a vehicle-mounted fragrance device. Thus, when a user uses the vehicle-mounted fragrance device, it can only provide fragrance gas of one smell, which cannot meet the user's demand for fragrance flavor diversity.

[0046] In view of this, an embodiment of the present application provides a vehicle-mounted fragrance device, which is applied to a vehicle, and includes a plurality of fragrance chambers, each of which can be equipped with a fragrance component. The vehicle-mounted fragrance device is also provided with a switching component, and by rotating the switching component, different fragrance chambers can be connected to the vehicle cabin, so that the air in the vehicle cabin can flow through the fragrance chamber and release the fragrance gas in the fragrance chamber into the vehicle cabin. In other words, users can choose different fragrance chambers according to their needs, which meets the user's demand for a variety of fragrance flavors.

[0047] See also Figures 1 to 13The present embodiment provides a vehicle-mounted fragrance device 10, which is applied to a vehicle and is used to release gas with a specific smell into the interior of the vehicle cabin to improve the comfort of the vehicle driver and passengers.

[0048] The vehicle-mounted fragrance device 10 includes a body 100, which has a plurality of fragrance chambers 110 arranged in parallel, and the number of the fragrance chambers 110 can be two, three or more. The fragrance chamber 110 has a containing space, and the fragrance chamber 110 is used to install the fragrance component 600, so that the fragrance chamber 110 can be filled with fragrance gas.

[0049] The fragrance component 600 may be a fragrance bottle containing fragrance liquid, or a fragrance block. This embodiment does not limit the type of the fragrance component 600. Taking the fragrance bottle as an example, the fragrance bottle may be installed inside the fragrance chamber 110, or the body of the fragrance bottle may be fixedly connected to the side wall of the fragrance chamber 110, and the opening end of the fragrance bottle may extend into the fragrance chamber 110.

[0050] Since there are multiple fragrance chambers 110, each fragrance chamber 110 can be installed with a fragrance component 600, that is, the vehicle-mounted fragrance device 10 is installed with multiple fragrance components 600, wherein the types of the multiple fragrance components 600 can be the same or different, for example, some fragrance components 600 are fragrance bottles, and some fragrance components 600 are fragrance blocks.

[0051] In some embodiments, among the plurality of fragrance components 600, at least two fragrance components 600 have different fragrance smells. Exemplarily, when the number of fragrance components 600 is two, the fragrance smells of the two fragrance components 600 are different. When the number of fragrance components 600 is three, the fragrance smells of the three fragrance components 600 may all be different. Alternatively, the fragrance smells of any two fragrance components 600 among the three fragrance components 600 are the same.

[0052] In some embodiments, each fragrance chamber 110 has an air inlet 111 and an air outlet 112, so that the air in the cabin can enter the fragrance chamber 110 through the air inlet 111, and the air in the cabin is mixed with the fragrance gas in the fragrance chamber 110. After the air and the fragrance gas are mixed, they can be discharged into the cabin through the air outlet 112 to improve the comfort of the user.

[0053] In some embodiments, the vehicle-mounted fragrance device 10 also includes a switching member 200, the switching member 200 has an inlet channel 211 and a first outlet channel 212, the air inlet end of the inlet channel 211 and the air outlet end of the first outlet channel 212 are both connected to the vehicle cabin, the switching member 200 is rotatably connected to the main body 100, and the rotating shaft of the switching member 200 is parallel to the arrangement direction X of the multiple fragrance chambers 110. In this way, during the rotation of the switching member 200, the relative position of the switching member 200 and each fragrance chamber 110 does not change, while the relative position of the inlet channel 211 and the first outlet channel 212 along the circumference of the switching member 200 changes.

[0054] The user can manually drive the switch 200 to rotate. In some embodiments, the vehicle-mounted fragrance device 10 can also be provided with a switch driver 400, such as a motor, and the output end of the switch driver 400 is connected to the switch 200, so that the switch driver 400 can automatically drive the switch 200 to rotate, which is convenient to operate.

[0055] When the switching member 200 is rotated to different angles, the switching member 200 is configured to selectively connect the introduction channel 211 to the air inlet 111 of one of the fragrance chambers 110, and connect the first outlet channel 212 to the air outlet 112 of the same fragrance chamber 110. That is, when the switching member 200 is rotated to different angles, the introduction channel 211 and the first outlet channel 212 can be connected to any one of the multiple fragrance chambers 110 at the same time, that is, the outlet end of the introduction channel 211 is connected to the air inlet 111 of the fragrance chamber 110, and the air inlet end of the first outlet channel 212 is connected to the air outlet 112 of the fragrance chamber 110, and the air in the cabin can enter the fragrance chamber 110 through the introduction channel 211, and the air is mixed with the fragrance gas in the fragrance chamber 110 and then discharged into the cabin through the first outlet channel 212, that is, the fragrance gas in the fragrance chamber 110 is released into the cabin.

[0056] It can be understood that the switch member 200 may have a plurality of preset rotation strokes, and each fragrance chamber 110 corresponds to a rotation stroke. In this way, when the rotation strokes of the switch member 200 are different, the fragrance chamber 110 corresponding to the rotation stroke is connected to the vehicle cabin through the switch member 200, that is, the fragrance chamber 110 is connected to the outside world. In this way, as needed, the user can switch the switch member 200 between different rotation strokes to connect different fragrance chambers 110 to the vehicle cabin, that is, the vehicle-mounted fragrance device 10 can provide fragrance gases with different flavors to meet the user's diverse needs for fragrance flavors.

[0057] When one of the fragrance chambers 110 is connected to the vehicle cabin, air enters the fragrance chamber 110 through the inlet channel 211 and is then discharged into the vehicle cabin through the first outlet channel 212. To facilitate gas flow, the vehicle fragrance device 10 further includes a fan 500, which may be disposed at the outlet end of the first outlet channel 212 to drive gas flow.

[0058] In some embodiments, the air inlets 111 and the air outlets 112 of different fragrance chambers 110 may be arranged at intervals along the circumference of the switching member 200 (not shown). In this way, when the rotation stroke of the switching member 200 is different, the switching member may only be provided with one set of inlet channels 211 and the first outlet channels 212, and the air inlets 111 and the first outlet channels 212 are connected to different fragrance chambers 110 through the set of inlet channels 211 and the first outlet channels 212.

[0059] To simplify the structure of the vehicle-mounted fragrance device 10, the air inlets 111 and the air outlets 112 of the different fragrance chambers 110 may also be arranged along the arrangement direction X (eg Fig.10 shown).

[0060] In some embodiments, the switch member 200 has a plurality of switch chambers 210, and the switch chambers 210 correspond to the fragrance chambers 110 one by one (eg, Figures 4 to 8 As shown in the figure, a plurality of switching chambers 210 are arranged along the arrangement direction X, that is, each fragrance chamber 110 is correspondingly provided with a switching chamber 210. For example, when the number of fragrance chambers 110 is three, the switching member 200 is correspondingly provided with three switching chambers 210, and each switching chamber 210 is provided with an inlet channel 211 and a first outlet channel 212. In this way, when one of the fragrance chambers 110 is connected to the vehicle cabin, the fragrance chamber 110 is connected to the vehicle cabin through the corresponding switching chamber 210, and at this time, the remaining switching chambers 210 are in a closed state, so that the remaining fragrance chambers 110 are isolated from the interior of the vehicle cabin to avoid odor contamination.

[0061] To switch between different fragrance chambers 110, the switch member 200 can be rotated to cooperate with the axial movement of the switch member 200 (not shown). In this embodiment, the fragrance chambers 110 can be switched only by the rotation of the switch member 200, which is easy to operate.

[0062] In some embodiments, the air inlet 111 and the air outlet 112 are arranged along the arrangement direction X, and correspondingly, the air outlet end of the introduction channel 211 and the air inlet end of the first outlet channel 212 are arranged along the arrangement direction X.

[0063] Specifically, the air inlet 111 and the air outlet 112 of the same fragrance chamber 110 may be arranged at intervals along the circumference of the switching member 200. In this case, the air outlet end of the introduction channel 211 and the air inlet end of the first outlet channel 212 are arranged at intervals along the circumference of the switching member 200 (not shown). Alternatively, the air inlet 111 and the air outlet 112 of the same fragrance chamber 110 may be located at the same position along the circumference of the switching member 200 (e.g. Fig.10 As shown), at this time, the air outlet end of the inlet channel 211 and the air inlet end of the first outlet channel 212 are located at the same position in the circumferential direction of the switching member 200.

[0064] The air inlets 111 and the air outlets 112 of the different fragrance chambers 110 are located at the same position in the circumferential direction of the switching element 200 (eg Fig.10 ), that is, the center line of the air inlets 111 of different fragrance chambers 110 is parallel to the axis of the switching member 200, and the center line of the air outlets 112 of different fragrance chambers 110 is parallel to the axis of the switching member 200. In some embodiments, see Fig.10 When the air inlet 111 and the air outlet 112 of the same fragrance chamber 110 are located at the same position of the switching member 200 in the circumferential direction, the center connecting lines of the air inlets 111 of different fragrance chambers 110 and the center connecting lines of the air outlets 112 of different fragrance chambers 110 coincide with each other and are both parallel to the axis of the switching member 200 .

[0065] In order to switch between different fragrance chambers 110, the air outlet ends of the inlet channels 211 and the air inlet ends of the first outlet channels 212 of different switching chambers 210 are arranged at intervals along the circumference of the switching member 200 (eg Fig.11 and Fig.12 As shown), in this way, the positions of the air inlet 111 and the air outlet 112 of the fragrance chamber 110 can be used as a reference. When the switching member 200 is rotated to different angles, that is, the rotation stroke of the switching member 200 is different, different circumferential positions of the switching member 200 are relative to the reference, that is, the air outlet end of the inlet channel 211 and the air inlet end of the first outlet channel 212 of different switching chambers 210 are relative to the reference. At this time, the switching chamber 210 and the fragrance chamber 110 corresponding to the rotation stroke are connected to each other.

[0066] In order to switch between different fragrance chambers 110 through the switching member 200, in some embodiments, the air inlets 111 and the air outlets 112 of different fragrance chambers 110 are arranged at intervals along the circumference of the switching member 200 (not shown), that is, the air inlets 111 of different fragrance chambers 110 are arranged at intervals along the circumference of the switching member 200, and the air outlets 112 of different fragrance chambers 110 are arranged at intervals along the circumference of the switching member 200. In some embodiments, at this time, the air inlet 111 and the air outlet 112 of the same fragrance chamber 110 can be located at the same position of the circumference of the switching member 200.

[0067] In this way, the air outlet ends of the inlet channels 211 and the air inlet ends of the first outlet channels 212 of different switching chambers 210 are located at the same position in the circumferential direction of the switching member 200. In this way, when the switching member 200 is rotated to different angles, that is, when the rotation stroke of the switching member 200 is different, only one of the switching chambers 210 can be connected to the corresponding fragrance chamber 110, that is, by rotating the switching member 200, it is possible to switch between different fragrance chambers 110.

[0068] In some embodiments, the switch member 200 has a fragrance outlet 220 , and there may be multiple fragrance outlets 220 (not shown), that is, each of the first outlet channels 212 of different fragrance chambers 110 has a corresponding fragrance outlet 220 .

[0069] In some embodiments, the number of the fragrance outlet 220 can also be one, and the air outlet ends of the multiple first outlet channels 212 are all connected to the fragrance outlet 220. That is to say, when each fragrance chamber 110 is connected to the vehicle cabin, the fragrance gas is discharged from the fragrance outlet 220, and the structure of the vehicle-mounted fragrance device 10 is relatively simple.

[0070] Specifically, the switching member 200 is further provided with a second outlet channel 230, which extends along the arrangement direction X. One end of the second outlet channel 230 passes through the side wall of the switching member 200 and constitutes a fragrance outlet 220; the second outlet channel 230 is provided with a first connecting port 231 at a position corresponding to each first outlet channel 212, and the first connecting port 231 constitutes an outlet end of the first outlet channel 212 to introduce the gas in the first outlet channel 212 into the second outlet channel 230.

[0071] In this way, when the fragrance chamber 110 is connected to the vehicle cabin, air first enters the fragrance chamber 110 through the inlet channel 211. After the air is mixed with the fragrance gas, the mixed gas enters the second outlet channel 230 through the first outlet channel 212 and is then discharged into the vehicle cabin. In other words, the fragrance gas from different fragrance chambers 110 is discharged through the second outlet channel 230.

[0072] In some embodiments, the switching member 200 includes a switching member cylinder 201 and a partition 202, wherein the partition 202 is disposed in the switching member cylinder 201. The switching member cylinder 201 and the partition 202 may be integrally formed, or the partition 202 may be detachably disposed in the switching member cylinder 201, such as by screwing or clamping.

[0073] The switching member cylinder 201 is a cylindrical structure, and the partition 202 has a partition cylinder 203 and a plurality of partition protrusions 204 protruding from the outside of the partition cylinder 203. Different switching chambers 210 are separated by the partition protrusions 204, and the inlet channel 211 and the first outlet channel 212 in a single switching chamber 210 are also separated by the partition protrusions 204.

[0074] The portion of the switching member cylinder 201 corresponding to the inlet channel 211 is provided with two third communication ports 205 to respectively constitute the air inlet end of the inlet channel 211 and the air outlet end of the inlet channel 211. The portion of the switching member cylinder 201 corresponding to the first outlet channel 212 is provided with a fourth communication port 206, which constitutes the air inlet end of the first outlet channel 212. That is, each switching chamber 210 is provided with two third communication ports 205 and one fourth communication port 206, and the relative positions of the third communication ports 205 and the fourth communication ports 206 corresponding to a single switching chamber 210 are as follows: Fig.11 As shown in the dashed ellipse, there are two third communication openings 205 and one fourth communication opening 206.

[0075] It can be understood that the first communication port 231 is disposed at a position of the partition cylinder 203 corresponding to the first outlet passage 212 .

[0076] In some embodiments, there is a curved flow channel between the air inlet 111 and the air outlet 112 of the fragrance chamber 110. In this way, after the air in the vehicle cabin enters the fragrance chamber 110 through the inlet channel 211, it will flow in the fragrance chamber 110 along the curved flow channel to fully disturb the fragrance gas in the fragrance chamber 110 and mix with the fragrance gas evenly. After the mixed fragrance gas is discharged, it is also helpful to stimulate the fragrance component 600 to emit fragrance gas.

[0077] The curved flow channel may be approximately S-shaped. In some embodiments, a partition 120 is provided in the fragrance chamber 110, and the partition 120 may be a flat plate (such as Figure 5 and Fig.10The partition 120 is a fixed plate (shown) or a bent plate (not shown), such as a V-shaped plate, one end of the partition 120 is connected to the side wall of the fragrance chamber 110, such as by welding or integral molding, and the other end of the partition 120 extends between the opposite side walls of the fragrance chamber 110, that is, there is a gap between the other end of the partition 120 and the inner wall surface of the fragrance chamber 110, and the air inlet 111 and the air outlet 112 are both located at the fixed end of the partition 120, and are respectively located on both sides of the partition 120. In this way, after the air enters the fragrance chamber 110, the air first disturbs the fragrance gas of the fragrance chamber 110 on the side where the air inlet 111 is set on the partition 120, and drives the mixed gas to flow toward the side of the gap, and then, the mixed gas continues to disturb the fragrance gas of the fragrance chamber 110 on the side where the air outlet 112 is set on the partition 120, and drives the mixed gas to be discharged through the air outlet 112.

[0078] In this way, by providing the partition 120, the inner cavity of the fragrance chamber 110 can be divided into a substantially U-shaped flow channel to fully disturb the gas in the fragrance chamber 110, and the structure is relatively simple.

[0079] In some embodiments, the switching member 200 is provided with a first positioning protrusion 240 (eg, Figure 3 , Fig.11 and Fig.12 As shown), the body 100 is provided with a second positioning protrusion 130 (as shown Fig.10 As shown in FIG. 1 , the first positioning protrusion 240 and the second positioning protrusion 130 may both be columnar protrusions. When the first positioning protrusion 240 and the second positioning protrusion 130 abut against each other, the air inlet 111 of each fragrance chamber 110 and the introduction channel 211 are mutually isolated, and the air outlet 112 of each fragrance chamber 110 and the first outlet channel 212 are mutually isolated. That is, when the first positioning protrusion 240 and the second positioning protrusion 130 abut against each other, each switching cavity 210 is in a closed state, and each fragrance chamber 110 is not connected to the vehicle cabin.

[0080] It is understandable that the position of the switching member 200 when the first positioning protrusion 240 and the second positioning protrusion 130 are in contact can be used as the initial position of its rotation stroke. In this way, when the user is not using the vehicle-mounted fragrance device 10, the switching member 200 can be in the initial position to prevent the fragrance gas from leaking.

[0081] At the same time, by setting the initial position of the switching member 200, different rotation strokes can be set corresponding to different fragrance chambers 110. In this way, when the user uses the vehicle-mounted fragrance device 10, the rotation stroke of the switching member 200 relative to the initial position can be adjusted by the forward and reverse rotation of the switching member 200 to switch between different fragrance chambers 110.

[0082] In some embodiments, see Figures 4 to 10The main body 100 is provided with an installation cavity 140, and the switching member 200 is rotatably installed in the installation cavity 140, that is, the installation cavity 140 can be a columnar cavity, and the outer wall surface of the switching member 200 is in contact with the inner wall surface of the installation cavity 140. Among them, the installation cavity 140 extends along the arrangement direction X, and the installation cavity 140 and each fragrance chamber 110 are provided with a side wall for isolation. Correspondingly, the air inlet 111 and the air outlet 112 are arranged on the side wall between the installation cavity 140 and the fragrance chamber 110, that is, the installation cavity 140 is connected with each fragrance chamber 110 respectively. In this way, after the switching member 200 is installed in the installation cavity 140, the switching cavity 210 can be connected with the corresponding fragrance chamber 110.

[0083] In some embodiments, in order to connect the introduction channel 211 with the vehicle cabin, a second communication port 141 penetrating both the inner and outer sides is further provided on the side wall of the installation cavity 140, and the second communication port 141 is configured to communicate with the introduction channel 211 when one of the fragrance chambers 110 is connected with the outside. When there are multiple switching cavities 210, each switching cavity 210 is provided with a corresponding second communication port 141.

[0084] It can be understood that when one of the switching chambers 210 is connected to the corresponding fragrance chamber 110, the other switching chambers 210 are in a closed state to isolate the other fragrance chambers 110 from the vehicle cabin. At this time, the air inlet 111 and the air outlet 112 of the fragrance chamber 110 in the closed state are opposite to the outer wall surface of the corresponding switching member 200, that is, the air inlet 111 or the air outlet 112 is blocked by the outer wall surface of the switching member 200 to prevent the air in the vehicle cabin from entering the fragrance chamber 110 through the air inlet 111 or the air outlet. At this time, the outer wall surface of the switching member 200 may block or not block the second communication port 141.

[0085] It can be understood that when the user rotates the switching member 200 to switch to the target fragrance chamber with the target smell fragrance gas, the switching member 200 rotates forward and reversely. During the rotation of the switching member 200, the non-target fragrance chamber will be temporarily connected to the cabin, causing the fragrance gas with non-target smell to be discharged into the cabin and the occurrence of cross-odor.

[0086] In some embodiments, the vehicle-mounted fragrance device 10 further includes a plurality of switch components (not shown) that can be opened and closed. The switch components may be switch plates, switch blocks, etc. The material of the switch components may be plastic, and the material of the switch components may be elastic components, such as rubber. Exemplarily, the elastic switch components are normally in a closed state. When the air inlet 111 of one of the fragrance chambers 110 is connected to the introduction channel 211, and the air outlet 112 is connected to the first outlet channel 212, the switch components at the corresponding air inlet 111 and air outlet 112 can be opened under the push of the airflow.

[0087] In some embodiments, the switch components are respectively arranged at the air inlet 111 and the air outlet 112 of each fragrance chamber 110, and the switch components can be rotatably connected or slidably connected to the side wall of the fragrance chamber 110. When the switch components avoid the air inlet 111 and the air outlet 112, the air inlet 111 and the air outlet 112 are in an open state, and when the switch components cover the positions of the air inlet 111 and the air outlet 112, the air inlet 111 and the air outlet 112 are in a closed state. It can be understood that the switch components arranged at the position of the air outlet 112 can also be arranged at the position of the fourth connecting port 206 of the switching component 200.

[0088] In some embodiments, in order to turn on or off the switch, the vehicle-mounted fragrance device 10 may be provided with a switch driver, such as a micro motor well known to those skilled in the art, the switch driver is connected to the switch and drives the switch to move or rotate relative to the body 100. In this way, when the switch driver is in a stopped state, the switch state of the switch is not affected by the flow of air.

[0089] In some embodiments, when the air inlet 111 of one of the fragrance chambers 110 is in communication with the introduction channel 211 and the air outlet 112 is in communication with the first outlet channel 212 , the switch components of the other fragrance chambers 110 are in a closed state.

[0090] That is, when the target fragrance chamber is connected to the vehicle cabin, the switch components at the air inlet 111 and the air outlet 112 of the target fragrance chamber are both in an open state, so that the introduction channel 211 is connected to the air inlet 111, and the first outlet channel 212 is connected to the air outlet 112. Correspondingly, the switch components of the remaining fragrance chambers 110 are all in a closed state to prevent the non-target fragrance chamber from being connected to the vehicle cabin during the rotation of the switching component 200.

[0091] In some embodiments, the vehicle-mounted fragrance device 10 further includes a protective shell 300 (eg, Figure 1 As shown in the figure, the body 100 is detachably installed in the protective shell 300. That is, the protective shell 300 is arranged around the outside of the body 100 and the switching member 200 to protect the body 100 and the switching member 200, and the safety is relatively high. In order to facilitate the disassembly and maintenance of the body 100 and the switching member 200, the protective shell 300 includes a protective shell body and a cover body, and the cover body can be connected with the protective shell body by snapping. When the cover body and the protective shell body are separated from each other, the body 100 and the switching member 200 arranged in the protective shell body can be exposed.

[0092] The shape of the protective shell 300 can be a cube, a cylinder or other shapes, and the material of the protective shell 300 can be plastic, etc., and the weight is relatively small. The body 100 can be detachably connected to the protective shell 300, such as screw connection or clamp connection, and the disassembly and assembly are convenient.

[0093] In some embodiments, the protective shell 300 is provided with a first hole and a second hole, the first hole is used to introduce air into the protective shell 300, the first hole may be one or more, and the first hole may be a bar hole, a circular hole, etc. The second hole is connected to the air outlet of the fan 500, and is used to guide the fragrance gas out of the protective shell 300 through the second hole, the number of the second hole may be one or more, and the second hole may be a bar hole, a circular hole, etc.

[0094] The vehicle fragrance device 10 is applied to a vehicle, the vehicle includes a vehicle body and the vehicle fragrance device 10, the vehicle body is provided with a cabin, and the vehicle fragrance device 10 is arranged in the cabin of the vehicle body. The structure, function and working principle of the vehicle fragrance device 10 have been described in the above embodiment, and will not be repeated in this embodiment.

[0095] By adopting the above-mentioned vehicle-mounted fragrance device 10, in this embodiment, the user can change the smell of the fragrance in the vehicle cabin as needed to meet the user's diverse needs for the fragrance smell.

[0096] In some embodiments, the vehicle includes a control unit, which is connected to the switch 200, that is, the control unit is electrically connected to the switch driver 400, and is used to control the switch 200 to rotate by controlling the switch driver 400, so as to simultaneously connect any one of the multiple fragrance chambers 110 to the inlet channel 211 and the first outlet channel 212. It can be understood that the control unit is also electrically connected to the fan 500, and is used to control the start and stop and the speed of the fan 500.

[0097] It is understandable that when the user does not use the vehicle fragrance device 10, the control unit controls the switch member driving member 400 and the fan 500 to stop. At this time, the first positioning protrusion 240 abuts against the second positioning protrusion 130, and the switch member 200 is in the initial position of the rotation stroke.

[0098] To facilitate the control of the rotation of the switching member 200, after a plurality of fragrance members 600 are installed on the vehicle-mounted fragrance device 10, the control unit can identify the type of fragrance member 600 corresponding to each fragrance chamber 110. After the control unit receives the control signal for selecting the type of fragrance smell, the control unit can control the switching member driving member 400 to drive the switching member 200 to rotate forward and reversely to switch to the target fragrance smell required by the user. For example, the vehicle can be provided with a display screen, which is electrically connected to the control unit. The display screen can display the type of fragrance. The user selects the type of fragrance smell by touching the display screen. After receiving the touch control signal, the control unit can switch the switching member 200 to the corresponding fragrance chamber 110 accordingly to switch to the target fragrance smell required by the user.
