The air treatment device of the present invention further comprises a fragrance means 10. The fragrance apparatus 10 includes at least a fragrance emitting assembly 11 (see fig. 1) and a fragrance distribution assembly 12 (see fig. 3). As can be seen more clearly in fig. 2a to 3, the perfuming assembly 11 may comprise a perfuming film 20, the perfuming film 20 being attached to a side wall of at least one air guiding vane 4, preferably a perfuming film 20 being attached to two or more air guiding vanes 4, and more preferably a perfuming film 20 being attached to each air guiding vane 4. The aromatic film 20 may be attached to the air guide blade 4 by means of an adhesive, a tab structure, or the like.

The air guide vane 4 with the attached fragrant film 20 may include a hollow chamber 15 (as shown in fig. 2 d), for example, a part (e.g., a lower part) of the air guide vane 4 is formed as a hollow structure, or the entire air guide vane 4 is formed as a hollow structure. A fragrance such as an essential oil may be stored in the hollow chamber. In addition, at least one hole may be formed in the sidewall of the air guide vane 4 at a position corresponding to the hollow chamber 15, the fragrance film 20 attached to the air guide vane 4 covers the hole, and the fragrance stored in the hollow chamber may escape from the hole and be adsorbed into the fragrance film 20. Preferably, a plurality of minute holes 14 (see fig. 2b and 2c) are provided on the side wall of the air guide vane 4 so that the perfume can be more uniformly applied to the fragrant film 20. Further, it is preferable that the perfume film 20 has a siphon function, for example, the perfume film 20 is a moisture permeable film, a test paper, etc., so that, for example, when the hole on the air guide blade 4 is located at the lower part or even the bottom of the perfume film 20, the perfume applied to the perfume film 20 can permeate upward by the siphon function, thereby helping to uniformly distribute the perfume throughout the perfume film 20.

The fragrance absorbed into the perfuming film 20 is gradually volatilized and carried away by the treated air blown out through the outlet 3 and dispersed into the surrounding environment.

The cloth scent assembly 12 may specifically include a cloth scent port, as can be seen more clearly in fig. 3. In the first embodiment, the fragrance distribution opening opens into the hollow chamber of the air guide vane 4. The hollow chamber can be supplemented with perfume through the cloth perfume mouth. As shown in fig. 3, the fragrance dispensing opening of the fragrance dispensing assembly 12 is preferably provided at a side portion of the air guide blade 4, more preferably at a lower portion of the air guide blade 4.

As shown in FIGS. 1-3, the fragrance apparatus 10 may further include a fragrance storage unit 13, the fragrance storage unit 13 being configured to store a fragrance. Extending between the fragrance storage unit 13 and the cloth fragrance assembly 12 is a fragrance delivery tube 50, the fragrance delivery tube 50 being shown in figures 1-3, from which it can be seen that the fragrance delivery tube 50 is connected at one end to the fragrance storage unit 13 and at the other end to the cloth fragrance assembly 12, for example to a cloth fragrance opening.

The configuration of the fragrance delivery tube 50 extending from the fragrance storage unit 13 is shown in figures 4a and 4 b. In the structure of the perfume delivery pipe 50 shown in fig. 4a and 4b, the perfume delivery pipe 50 includes a main pipe 51 and at least two branch pipes 52, one end of the main pipe 51 is connected to the perfume storing unit 13, and the branch pipes 52 branch from and extend from the main pipe 51 and are connected to the respective air guide vanes 4 provided with the perfume emitting films 20.

Preferably, the number of branch pipes 52 is equal to the number of air guide vanes 4 provided with the perfuming film 20, that is, each air guide vane 4 has a corresponding branch pipe 52. Of course, it is also possible that one branch pipe corresponds to a plurality of air guiding blades 4, or a plurality of branch pipes are connected to the same air guiding blade 4, without departing from the scope of the present invention.

In another structure, the perfume delivery pipe 50 may include only the manifold 51, the manifold 51 extends from the perfume storage unit 13 and is connected to one of the air guide vanes 4, and the hollow chambers of the air guide vanes 4 may communicate with each other. For example, a communication pipe is provided in the frame 2 of the panel 1, and the hollow chambers of the air guide vanes 4 are all communicated with the communication pipe. Such a configuration is also within the scope of the present invention.

Further, as shown in the preferred construction of the fragrance delivery tube 50 in fig. 4a and 4b, a first flow regulating valve 53 is provided on the manifold 51 for regulating the amount of fragrance flowing out of the fragrance reservoir 30 of the fragrance storage unit 13. Furthermore, as shown more clearly in fig. 4b, a second flow regulating valve 54 is provided on at least one branch duct 52 for regulating the amount of fragrance flowing into the corresponding specific air guiding vane 4. The second flow rate adjustment valve 54 can distribute a vector between the air guide blades 4, thereby adjusting the ratio of the perfume flowing into each air guide blade 4. Preferably, a second flow regulating valve 54 is provided on the plurality of branch pipes 52, and more preferably, a second flow regulating valve 54 is provided on each branch pipe 52.

In the arrangement shown in fig. 4a and 4b, two (or possibly more) fragrance reservoirs 30 are included in the fragrance storage unit 13. In this case, a switching device 31 may be preferably provided between the perfume delivery pipe 50 and the perfume storage tank 30, and the switching device 31 may be, for example, a two-way three-way valve, and by the switching device 31, it is possible to control which perfume in the perfume storage tank 30 is distributed to the air guide blade 4. The two fragrance reservoirs 30 can contain different types of fragrances, respectively, and the application of different types of fragrances to different air guide vanes 4 can be controlled by operating the second flow control valve 54 on the branch pipe 52. Taking the structure shown in fig. 4a and 4b as an example, when the switching device 31 is switched to make the perfume in the left perfume storage tank 30 flow into the perfume delivery pipe 50, one of the two second flow rate adjusting valves 54 is controlled to be opened, and the other second flow rate adjusting valve 54 is controlled to be closed, so that the perfume in the left perfume storage tank 30 flows into the air guide blade 4 corresponding to the opened second flow rate adjusting valve 54. Similarly, when the switching device 31 is switched to apply the perfume in the right perfume reservoir 30, the above-mentioned one second flow regulating valve 54 may be controlled to be closed, and the above-mentioned other second flow regulating valve 54 may be controlled to be opened.

Of course, the fragrance storage unit 13 may also comprise only one fragrance reservoir 30, in which case the switching means 31 may then be omitted.

< second embodiment >

The structure of the second embodiment of the present invention will be described below with reference to fig. 5 and 6. Where, for the sake of brevity, the differences between the second embodiment and the first embodiment are mainly described, the technical features described above in relation to the first embodiment are also equally applicable to the second embodiment without the contrary description and without contradiction.

As shown in fig. 5, a fragrance film frame 21 is provided on the side wall of the air guide vane 4, and the fragrance film frame 21 is provided around the circumference of the fragrance film 20, or the fragrance film 20 can be accommodated in the fragrance film frame 21. The cloth nozzle of the cloth fragrance assembly 12 is attached to one side of the fragrance film frame 21 and is in contact with the fragrance film 20 provided in the fragrance film frame 21. Thus, in the second embodiment, the fragrance can be applied directly to the film 20 via the cloth orifice of the cloth scent assembly 12.

Further, a perfume delivery pipe 50 extending from the perfume storage unit 13 is connected to the cloth nozzle, whereby the perfume can be replenished from the perfume storage unit 13 to the fragrant film 20.

It can be seen that in this second embodiment, the fragrance distribution opening is provided on the fragrance film frame 21 of the fragrance film 20, and fragrance can be applied to the fragrance film 20, so that the wind guide blade 4 can guide wind without forming a hollow chamber as in the first embodiment. Of course, it is still within the scope of the present invention to provide the air guide blade 4 in a configuration including a hollow chamber in this second embodiment.

Fig. 6 shows the fragrant film frame 21 and the fragrant film 20 accommodated in the fragrant film frame 21. Wherein, a clasp 22 is formed on one side of the fragrant film frame 21, and the cloth fragrance mouth is connected to the fragrant film frame 21 by the structure of the clasp 22. Of course, the cloth orifice may be provided on the fragrance film frame 21 by other means, such as by welding, or the cloth orifice may be integrally formed on the fragrance film frame 21.

< third embodiment >

The structure of the third embodiment of the present invention will be described below with reference to fig. 7 and 8. Where, for the sake of brevity, the differences of the third embodiment from the first and second embodiments are mainly described, the technical features described above in relation to the first and second embodiments are equally applicable to the third embodiment without the contrary description and without contradiction.

Fig. 7 is a view similar to fig. 2, from which it can be seen that at least one end, preferably both ends, of the wind-guiding blade 4 are provided with a connection 41, by means of which connection 41 the wind-guiding blade 4 can be mounted to the frame 2. In the third embodiment of the present invention, the connecting portion 41 is provided in an at least partially hollow structure. The perfume can be contained in the hollow structure of the connecting portion 41, and preferably, at least one, preferably a plurality of holes are opened on the side wall of the connecting portion 41, and the holes are communicated to the inside of the hollow structure for volatilizing the perfume contained therein.

Alternatively, in the case where the guide vane 4 includes a hollow chamber, the hollow structure of the connecting portion 41 may communicate with the hollow chamber in the guide vane 4.

Alternatively, the perfuming film 20 may directly contact the hollow structure of the connecting portion 41, so that the hollow cavity in the air guiding vane 4 is an optional structure. In the case where the fragrant film 20 directly contacts the hollow structure in the connecting portion 41 at the lower portion of the air guide vane 4, the fragrant film 20 may also have a siphon function, so that the fragrance may be permeated upward by the siphon action, helping to uniformly distribute the fragrance over the entire fragrant film 20.

As shown more clearly in fig. 8, the cloth nozzle of the cloth fragrance assembly 12 may be formed in the connecting portion 41. Alternatively, the cloth nozzle may be formed integrally with the connecting portion 41.

< other modifications >

While the preferred embodiments of the present invention have been described, variations and modifications may be made based on the preferred embodiments.

For example, in the above-disclosed embodiment, the fragrance emitting film is provided, but it is also conceivable that the fragrance emitting film is not provided, and the hollow wind guide blade 4 itself is a part of the fragrance emitting member. For example, the hollow air guide vane 4 is provided with a hole, and a material that is air-permeable but liquid-impermeable is coated on the hole, thereby allowing the fragrance to slowly evaporate from the hole. Alternatively, an adsorbing material may be provided in the hollow air guide blade 4 to adsorb the liquid perfume to prevent the perfume from flowing out in the liquid state, but allow the perfume to evaporate and diffuse in the gaseous state.

For another example, in the configuration of the flavor delivery tube 50 shown in fig. 4, the first flow rate adjustment valve 53 may be omitted, and the amount of flavor applied to each air guide blade 4 may be adjusted only by the second flow rate adjustment valve 54. Alternatively, where only a single type of fragrance is applied, the second flow regulating valve 54 may be omitted. Even more, both the first flow amount adjustment valve 53 and the second flow amount adjustment valve 54 may be omitted.

Further, the air treatment apparatus described herein includes various known apparatuses having an air treatment function, such as an air conditioner, an air purifier, and an air freshener.

These and other obvious variations of the above are within the scope of the present invention.
