[0054] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0055] like Figure 13 , Figure 14 As shown, in one application scenario, the fragrance device 100 can be installed on the heat exchanger 300 of the indoor unit 1000 of the air conditioner. When the cross-flow fan 400 is working, a negative pressure is formed on one side of the heat exchanger 300, while a high pressure is formed on the side of the heat exchanger 300 where the fragrance device 100 is installed. Air flows from the high pressure to the low pressure, thereby blowing the fragrance gas of the fragrance device 100 out of the indoor unit 1000 of the air conditioner.

[0056] The following is for reference. Figures 1-12 The following describes a fragrance device 100 according to an embodiment of the present invention.

[0057] like Figure 1 , Figure 2 , Figure 3 As shown, the fragrance device 100 according to an embodiment of the present invention includes: a fragrance component 10 and a drive mechanism 20.

[0058] The fragrance assembly 10 includes a fragrance container 110, a fragrance element 120, and a support base 130. The fragrance container 110 has multiple independent fragrance chambers 1101, each fragrance chamber 1101 having an air outlet channel 1102 passing through it; each fragrance chamber 1101 is provided with a fragrance element 120; the support base 130 has two spaced-apart support parts 1301 and an air passage 1302 passing through the two support parts 1301. The two support parts 1301 abut against the side wall of the fragrance container 110 to close the openings at both ends of each air outlet channel 1102.

[0059] The plurality of fragrance cavities 1101 correspond to the plurality of fragrance pieces 120, the plurality of fragrance pieces 120 can be different scents, and each fragrance cavity 1101 is an independent space that can ensure that the scents of each other are not confused. After the two support parts 1301 of the support seat 130 and the fragrance container 110 are matched, in the initial state, the plurality of air outlet channels 1102 are staggered with the air passage 1302, so that the fragrance pieces 120 in each fragrance cavity 1101 cannot release fragrance outward. When the fragrance container 110 moves on the two support parts 1301, the plurality of air outlet channels 1102 can be respectively communicated with the air passage 1302, so that different fragrance gases can be selectively released to meet the preferences of different users.

[0060] For example, the fragrance cavity 1101 is provided as four, the fragrance piece 120 is a fragrance block or a fragrance stick, and the fragrance piece 120 is provided as four. The four fragrance pieces 120 can be respectively "morning vitality fragrance", "forest fresh fragrance", "enjoy time heart fragrance", and "sweet sleep fragrance" according to their scent types and functions. Users can select the above four different fragrance types according to personal preferences.

[0061] In addition, the plurality of fragrance pieces 120 can be the same scent, so that the user can select the next fragrance piece 120 for use after the previous fragrance piece 120 is used up.

[0062] The driving mechanism 20 is connected with the fragrance container 110 to drive the fragrance container 110 to move relative to the support part 1301, so that the air outlet channel 1102 of the plurality of fragrance cavities 1101 and the air passage 1302 are switched to communicate.

[0063] For example, when the fragrance piece 120 of the first fragrance is selected, the driving mechanism 20 drives the fragrance container 110 to move a distance, so that the air outlet channel 1102 corresponding to the first end of the fragrance cavity 1101 is aligned with the air passage 1302, the two channels are communicated, and the air carries the fragrance gas in the first end of the fragrance cavity 1101 when passing through the air passage 1302.

[0064] When the fragrance piece 120 of the second fragrance is selected, the driving mechanism 20 drives the fragrance container 110 to continue to move a distance, at this time, the air outlet channel 1102 corresponding to the first end of the fragrance cavity 1101 is staggered with the air passage 1302, the first end of the air outlet channel 1102 is closed, and the air outlet channel 1102 corresponding to the second fragrance cavity 1101 is aligned with the air passage 1302, the air carries the fragrance gas in the second fragrance cavity 1101 when passing through the air passage 1302.

[0065] By analogy, by driving the fragrance container 110 to move through the driving mechanism 20, the air outlet channel 1102 of the different fragrance cavity 1101 can be selected to be communicated with the air passing channel 1302, and the fragrance gas of the fragrance element 120 in the corresponding fragrance cavity 1101 can be released.

[0066] According to the fragrance device 100 provided by the embodiment of the present application, the fragrance device 100 is provided by comprising the fragrance assembly 10 and the driving mechanism 20, the fragrance assembly 10 comprises the fragrance container 110, the fragrance element 120 and the support seat 130, the fragrance container 110 has a plurality of independent fragrance cavities 1101, each of the fragrance cavities 1101 has the air outlet channel 1102 penetrating through the fragrance cavity 1101, the fragrance element 120 is arranged in each of the fragrance cavities 1101, the support seat 130 has the two support parts 1301 and the air passing channel 1302 penetrating through the two support parts 1301, the two support parts 1301 abut against the two side walls of the fragrance container 110, and the driving mechanism 20 drives the fragrance container 110 to move relative to the support part 1301, so that one of the plurality of air outlet channels 1102 and the air passing channel 1302 are communicated, and the different fragrance elements 120 can be opened or closed, so that the user can intelligently control and adjust the corresponding fragrance element 120 according to personal preferences.

[0067] In some embodiments of the embodiment of the present application, as shown in Figure 2 , Figure 3 The air passing channel 1302 comprises a plurality of sub-channels 13021, the plurality of sub-channels 13021 are configured to be matched with the air outlet channels 1102 of the plurality of fragrance cavities 1101 one by one, and when the driving mechanism 20 drives the fragrance container 110 to move relative to the support part 1301, one of the plurality of sub-channels 13021 and the air outlet channel 1102 of the corresponding fragrance cavity 1101 are communicated. The plurality of air outlet channels 1102 and the plurality of sub-channels 13021 are communicated one by one to release the fragrance element 120 in the corresponding fragrance cavity 1101, so that the driving mechanism 20 has a shorter moving stroke and simpler movement in the process of driving the fragrance container 110 to move, and the energy consumption of the driving mechanism 20 can be reduced.

[0068] It can be understood that one sub-channel 13021 is arranged around each air outlet channel 1102, when the fragrance element 120 of the corresponding function needs to be opened, the driving mechanism 20 only needs to drive the fragrance container 110 to move a small displacement, so that the air outlet channel 1102 on the fragrance cavity 1101 corresponding to the desired fragrance element 120 is communicated with the corresponding sub-channel 13021, without the need to communicate different air outlet channels 1102 with specific channels when different fragrance elements 120 are opened, so that the moving stroke of the fragrance container 110 can be greatly reduced, and the activity space of the fragrance container 110 can also be reduced, which is beneficial to reducing the volume of the fragrance device 100.

[0069] In some embodiments of the present invention, such as Figure 1 , Figure 3 As shown, multiple fragrance chambers 1101 are arranged along a first direction. The driving mechanism 20 drives the fragrance container 110 to move relative to the support 1301 along the first direction. In the initial state, each sub-channel 13021 and the corresponding air outlet channel 1102 are staggered. Among any two adjacent sub-channels 13021, the difference between the distance between one and the corresponding air outlet channel 1102 in the first direction and the distance between the other and the corresponding air outlet channel 1102 in the first direction is a constant.

[0070] like Figure 2 As shown, the first direction can be left and right. Multiple fragrance chambers 1101 are sequentially named as first fragrance chamber, second fragrance chamber, third fragrance chamber, fourth fragrance chamber, etc., from right to left. Multiple air outlet channels 1102 are sequentially named as first air outlet channel, second air outlet channel, third air outlet channel, fourth air outlet channel, etc., and multiple sub-channels 13021 are sequentially named as first sub-channel, second sub-channel, third sub-channel, fourth sub-channel, etc.

[0071] The difference between the distance between the first sub-channel and the first exhaust channel and the distance between the second sub-channel and the second exhaust channel is a fixed value. The difference between the distance between the third sub-channel and the third exhaust channel and the distance between the second sub-channel and the second exhaust channel is a fixed value. The difference between the distance between the fourth sub-channel and the fourth exhaust channel and the distance between the third sub-channel and the third exhaust channel is a fixed value.

[0072] When the first sub-channel and the first exhaust channel are connected, the drive mechanism 20 moves the fragrance container 110 by a certain value, which connects the second sub-channel and the second exhaust channel, releasing the fragrance gas from the second fragrance element 120. Then, the drive mechanism 20 moves the fragrance container 110 by the same value again, connecting the third sub-channel and the third exhaust channel, releasing the fragrance gas from the third fragrance element 120. Finally, the drive mechanism 20 moves the fragrance container 110 by the same value again, connecting the fourth sub-channel and the fourth exhaust channel, releasing the fragrance gas from the fourth fragrance element 120. This method simplifies the movement of the fragrance container 110 and simplifies the control of the drive mechanism 20.

[0073] For example, the "fixed value" is 5 cm, the fragrance container 110 moves right from the initial state, the driving mechanism 20 drives the fragrance container 110 to move right by 5 cm, the first sub-channel and the first air outlet channel are communicated; the driving mechanism 20 drives the fragrance container 110 to continue to move right by 5 cm, at this time, the fragrance container 110 is 10 cm away from the initial state, the second sub-channel and the second air outlet channel are communicated; the driving mechanism 20 drives the fragrance container 110 to continue to move right by 5 cm, at this time, the fragrance container 110 is 15 cm away from the initial state, the third sub-channel and the third air outlet channel are communicated; the driving mechanism 20 drives the fragrance container 110 to continue to move right by 5 cm, at this time, the fragrance container 110 is 20 cm away from the initial state, the fourth sub-channel and the fourth air outlet channel are communicated.

[0074] It should be noted that the above is only an example, the fixed value can also be other values, the first direction can also be other directions, the number of the fragrance cavity 1101, the air outlet channel 1102 and the sub-channel 13021 can also be other values, which will not be described here.

[0075] In some embodiments of the embodiments of the present application, as shown in Figure 3 One of the two support parts 1301 is provided with a plurality of first openings 13011, and the other is provided with a plurality of second openings 13012, the plurality of second openings 13012 and the plurality of first openings 13011 are one-to-one corresponding, and each second opening 13012 and the corresponding first opening 13011 jointly define a sub-channel 13021. For example, the two support parts 1301 are arranged in the up-down direction, the first opening 13011 and the corresponding second opening 13012 form a sub-channel 13021 which is communicated in the up-down direction, air can enter from the second opening 13012, then enter the fragrance cavity 1101 from the top of the air outlet channel 1102, and flow from the gap between the fragrance cavity 1101 and the fragrance piece 120, then carry the fragrance gas from the bottom of the air outlet channel 1102, and finally flow out from the first opening 13011.

[0076] In some embodiments of the embodiments of the present application, as shown in Figure 3 The second opening 13012 is provided at the air inlet end of the sub-channel 13021, and the hole width of the second opening 13012 gradually decreases along the air inlet direction of the sub-channel 13021. It can be understood that the shape of the second opening 13012 is trumpet-shaped, which can increase the flow of air and help the fragrance gas of the fragrance piece 120 to be released.

[0077] In some embodiments of the embodiments of the present application, as shown in Figure 3 , Figure 4As shown, the first direction can be the length direction of the support part 1301, the plurality of first openings 13011 and the plurality of second openings 13012 are arranged at intervals along the length direction of the support part 1301, and each first opening 13011 and each second opening 13012 extend along the width direction of the support part 1301. By increasing the size of the first openings 13011 and the second openings 13012, the air inlet amount and the air outlet amount can be increased, and the release of the fragrance gas can be accelerated.

[0078] In some embodiments of the embodiments of the present application, as shown in Figure 1 、 Figure 3 、 Figure 4 、 Figure 7 As shown, the support seat 130 is a box body, two support parts 1301 are arranged on opposite inner walls of the box body, one of the two support parts 1301 is provided with a first sealing rib 1301a arranged around the first opening 13011, and the other is provided with a second sealing rib 1301b arranged around the second opening 13012, and the first sealing rib 1301a and the second sealing rib 1301b abut against the two side walls of the fragrance container 110. The first sealing rib 1301a and the second sealing rib 1301b can play a sealing role, when air passes through the sub-channel 13021, the first sealing rib 1301a and the second sealing rib 1301b can block the air from diffusing to the air outlet channel 1102 at other positions, thereby avoiding the leakage of fragrance gas and confusion with the fragrance of other fragrance pieces 120.

[0079] In some embodiments of the embodiments of the present application, as shown in Figure 7 As shown, the box body includes a detachably connected upper box body 13001 and a lower box body 13002, the upper box body 13001 and the lower box body 13002 jointly define a first space 130a, the fragrance container 110 is arranged in the first space 130a, and the two support parts 1301 are arranged on opposite inner walls of the first space 130a. The box body is designed to be detachably connected with the upper box body 13001 and the lower box body 13002, so as to realize the installation or disassembly of the fragrance container 110.

[0080] In some embodiments of the embodiments of the present application, as shown in Figure 7 As shown, the upper box body 13001 and the lower box body 13002 are connected by a first buckle structure 60, the first buckle structure 60 includes a first clamping convex 610 and a first clamping groove 620, one of the first clamping convex 610 and the first clamping groove 620 is arranged on the upper box body 13001 and the other is arranged on the lower box body 13002, and the buckle connection structure is simple to use, and the installation or disassembly is simple.
