[0033] The realization of the purpose, functional features and advantages of the present invention will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0036] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if the meaning of "and / or" appearing in the full text is to include three parallel schemes, taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0037] As people's living standards improve, more and more people pay attention to the quality of life, and the requirements for air comfort are getting higher and higher. The dust accumulated in the air conditioner filter is easy to produce odor, or there is an odor problem in the environment itself, or the user has a demand for an indoor environment with fragrance. Therefore, we often use the fragrance device installed in the air conditioner to release the airflow with fragrance to overcome the above-mentioned air odor problem, or to improve comfort and meet user needs. However, the fragrance device in the prior art has a relatively single fragrance type. When different fragrance functions are required, it is also difficult to switch the fragrance type released by the fragrance device in time. Or there is a device in the prior art that switches the fragrance type through a solenoid valve, but the structure of the battery valve is complex and the manufacturing cost is high. Using the solenoid valve for the fragrance switching of the fragrance device is easy to cause the fragrance device to have a high damage rate, high maintenance difficulty, high cost, and large volume. At the same time, other ways of switching the fragrance type of the fragrance device in the prior art also have this disadvantage to a greater or lesser extent. In summary, the fragrance device in the prior art has the problem of a single fragrance type. In addition, the fragrance bottle in the prior art is generally installed inside the fragrance device. When the fragrance in the fragrance bottle is exhausted and the fragrance needs to be replaced, the fragrance device needs to be disassembled before replacement. This step is relatively complicated and not conducive to user operation. Optionally, the material that can emit fragrance in the fragrance device can be aromatherapy essential oils, aromatherapy candles, flowers, fragrant wood or perfume, etc. That is, after being passed through by the airflow, the fragrance molecules can be driven by the airflow.

[0038] See also Figure 1 , Figure 2The present invention proposes a fragrance device 10, which includes a base 11, a switching member 13, and a driving assembly 14. The base 11 is formed with an installation cavity, and the base 11 is provided with an air inlet 11a and an air outlet 11b connected to the installation cavity; the switching member 13 is movably arranged inside the installation cavity, and a plurality of accommodating cavities are arranged in the switching member 13, each of which is provided with a fragrance bottle 12, and the fragrance bottle 12 is provided with an air hole 12a connected to the accommodating cavity; in an optional embodiment, the number of the air holes 12a is multiple. The driving assembly 14 is connected to the switching member 13 to drive the switching member 13 to move in the installation cavity, so that the accommodating cavity can be connected to the air inlet 11a and the air outlet 11b in turn. Specifically, a plurality of accommodating cavities are provided with relatively independent fragrance bottles 12, and each fragrance bottle 12 can be placed in different types and different smells. According to the needs, the user can align the accommodating cavity where the spice bottle 12 containing different spices is placed with the air inlet 11a and the air outlet 11b. This can realize the switching of fragrances. This changes the existing situation that the fragrance device 10 has a single fragrance. In addition, the structure of the switching member 13 is relatively simple. The existing fragrance device 10 with fragrance switching function has a solenoid valve inside and a complex structure. The present invention can also solve the problem of complex fragrance switching and reduce the manufacturing cost of the fragrance device 10 with fragrance switching function.

[0039] See also Figure 3 In an optional embodiment, the switching member 13 includes a top plate 131, a bottom plate 133, and a plurality of partitions 132 disposed between the top plate 131 and the bottom plate 133, and a receiving chamber is formed between two adjacent partitions 132, and the driving assembly 14 drives the switching member 13 to rotate so that one of the receiving chambers is connected to the air inlet 11a and the air outlet 11b. Specifically, the switching member 13 is a rotating drum, which rotates in the base 11. Furthermore, in addition to the top plate 131, the bottom plate 133, and the partition 132, the switching member 13 is also provided with a support column connecting the top plate 131 and the bottom plate 133 in the middle, and a shaft hole for the shaft to pass through is formed at the support column, and a plurality of partitions 132 are arranged at intervals along the circumference of the support column. The driving assembly 14 extends into the shaft hole to drive the switching member 13 to rotate. In another embodiment, in addition to rotation, the switching member 13 can also switch the fragrance in other forms, such as sliding, pumping, etc. In another embodiment, the base 11 is provided with an air inlet 11a and an air outlet 11b, the switching member 13 moves axially relative to the base 11, and the accommodating cavity also corresponds to the axial arrangement of the base 11. The accommodating cavity aligned with the air inlet 11a and the air outlet 11b can be replaced by the axial movement of the switching member 13.

[0040] Please participate Figure 2 In an optional embodiment, the inner wall of the base 11 is provided with a raised portion 11c, and the raised portion 11c is provided between the air inlet 11a and the air outlet 11b. When one of the accommodating chambers is connected with the air inlet 11a and the air outlet 11b, the raised portion 11c and the two adjacent partitions 132 together form an air duct, and the air duct is used to guide the airflow through the fragrance bottle 12. Optionally, the base 11 includes a cylindrical base 11 body and an external drainage part, the switching member 13 is installed in the base 11 body, and the air inlet 11a, the air outlet 11b, and the raised portion 11c are all provided on the drainage part. To form an air duct that allows the airflow to pass through the fragrance bottle 12. In this way, most of the airflow can pass through the fragrance bottle 12 through the air duct, so that the airflow flowing out of the fragrance device 10 carries more fragrance, so as to improve the user experience.

[0041] In an optional embodiment, when one of the accommodating chambers is connected to the air inlet 11a and the air outlet 11b, the air inlet 11a is arranged between the protruding portion 11c and one of the partitions 132, and the air outlet 11b is arranged between the protruding portion 11c and the other partition 132. This arrangement is to avoid the situation where the air outlet 11b or the air inlet 11a is located on both sides of the partition 132 at the same time. That is, only one of the accommodating chambers is connected to the air inlet 11a and the air outlet 11b at a time. This arrangement can maximally prevent the fragrance bottles in the other accommodating chambers from affecting the fragrance device.

[0042] In an optional embodiment, there is a gap between the partition 132 and the inner wall of the base 11. During the rotation of the switching member 13, a small gap exists between the partition 132 and the inner wall of the base 11 for the smooth rotation of the switching member 13, but most of the airflow passing through this gap still flows in from the air inlet 11a, passes through the air hole 12a, passes through the fragrance bottle 12, and then flows out from the air outlet 11b.

[0043] See also Figure 4 , Figure 5. In an optional embodiment, the height of the spice bottle 12 is greater than the distance between the top plate 131 and the bottom plate 133, and the top plate 131 is provided with a through hole for the spice bottle 12 to extend out, and the bottom of the spice bottle 12 is detachably connected to the bottom plate 133. Existing spice bottles 12 are often fixedly connected to the spice device 10, or are provided inside the spice device 10. When the user wants to replace the spice in the spice bottle 12, or remove the spice bottle 12, the entire spice device 10 needs to be disassembled, and the steps are complicated and difficult. In the spice device 10 proposed in the present invention, the spice bottle 12 extends out from the switching member 13 through the through hole on the top plate 131. The user can easily remove the spice bottle 12 from the spice device 10 through the portion of the spice bottle 12 that extends out. It can be seen that Figure 4 is a top view of the top plate 131 of the switching member 13, Figure 5 The cross-sectional view along the line AA after the switch member 13 is equipped with the fragrance bottle 12. It can be seen that in addition to the shaft hole, the top plate 131 is also provided with a through hole for the fragrance bottle 12 to partially extend out. The number of the through holes corresponds to the number of the fragrance bottles 12.

[0044] It is worth noting that, in order to facilitate the removal of the spice bottle 12, although there is a gap between the inner wall of the through hole on the top plate 131 and the spice bottle 12, the width of this gap is small and has little effect on the airflow. When the airflow flows into the accommodating cavity through the air outlet 11b, due to the narrow gap between the partition 132 and the inner wall of the base 11, and the gap between the spice bottle 12 and the top plate 131, most of the airflow flows in from the air inlet 11a, or passes through the spice bottle 12 through the air hole 12a, and then flows out from the air outlet 11b. Brownian motion refers to the never-ending irregular motion of particles suspended in liquid or gas. It is named after the discovery of British botanist Brown. The diameter of the particles performing Brownian motion is generally 10-5 to 10-3 cm. When these small particles are in liquid or gas, due to the thermal motion of liquid molecules, the particles are collided with liquid molecules from all directions, and move when subjected to unbalanced collisions. Due to this unbalanced collision, the movement of the particles constantly changes direction, causing the particles to move irregularly. The intensity of Brownian motion increases as the temperature of the fluid increases. The working principle of the fragrance device 10 is to bring aroma molecules into the air through airflow, and the aroma molecules perform Brownian motion in the air. It can be seen that due to the existence of Brownian motion, the distribution of aroma molecules in the air is relatively dispersed, and more aroma molecules are needed to make the air fragrant.

[0045] Due to the existence of the gap between the partition 132 and the base 11, and the existence of the gap between the top plate 131 and the spice bottle 12, part of the airflow may flow out from the gap. Compared with the total amount of airflow passing through the spice device 10, this part of the airflow accounts for a small proportion. The airflow passing through the spice slot carries fragrance, mainly because the airflow carries fragrance compound molecules in the process of passing through the fragrance in the spice slot, and causes the fragrance compound molecules to diffuse in the air, so that it carries fragrance. If only a small part of the airflow enters the spice slot, after this part of the airflow merges with the rest of the airflow, the total amount of fragrance molecules it carries is small, and due to the diffusion phenomenon of fragrance molecules in the air, that is, irregular movement in the air. Finally, the concentration of fragrance molecules in the air is negligible and has almost no effect on the smell in the air.

[0046] See also Figure 6 In an optional embodiment, a mounting hole is provided at the top of the base 11, and the switching member 13 is installed in the base 11 through the mounting hole. A limiting ring 15 is also provided at the top of the base 11 to prevent the switching member 13 from escaping from the mounting hole, and a plurality of the fragrance bottles 12 are located inside the limiting ring 15. Specifically, the switching member 13 is installed in the base 11 through the mounting hole and connected to the driving mechanism. Then the limiting ring 15 is installed. Further, the diameter of the limiting ring 15 is smaller than the diameter of the mounting hole and smaller than the diameter of the switching member 13. However, since the fragrance bottle 12 at least partially extends out from the switching member 13, each fragrance bottle 12 is located inside the limiting ring 15. That is, the extended fragrance bottle 12 can be directly seen from the top of the fragrance device 10, but the setting of the limiting ring 15 will not affect the removal and placement of the fragrance bottle 12. Since the switching member 13 is in an active state inside the installation cavity, if the up and down movement of the switching member 13 is not restricted, the switching member 13 is easy to be removed from the base 11 through the installation hole. Further, the retaining ring can be installed outside the base 11, or between the base 11 and the switching member 13. For the convenience of installation, the limiting ring 15 is arranged inside the base 11, so that the limiting ring 15 can be directly installed outside the base 11 after the switching member 13 is placed.

[0047] See also Figure 3In an optional embodiment, a first magnetic member 123 is provided at the bottom of the spice bottle 12, and a corresponding second magnetic member 134 is provided on the bottom plate 133. Optionally, the first magnetic member 123 is an iron sheet, and the second magnetic member 134 is a permanent magnet. In another embodiment, the first magnetic member 123 and the second magnetic member 134 may also be permanent magnets. Optionally, a mounting seat for mounting the permanent magnet is also provided on the bottom plate 133. The spice bottle 12 is fixed in the switching member 13 by magnetic attraction. When the user needs to remove the spice bottle 12, he only needs to hold the part of the spice bottle 12 extending outside the top plate 131 and apply an upward force to the spice bottle 12 to easily remove it. There is no need to disassemble the spice device 10 separately, which simplifies the steps of replacing and replenishing the spice bottle 12. When the spice bottle 12 does not need to be removed, the first magnetic member 123 and the second magnetic member 134 are adsorbed together to firmly fix the spice bottle 12. In addition, the fragrance bottle 12 can be detachably fixed on the bottom plate 133 by means of snap connection or the like.

[0048] See also Figure 3 In an optional embodiment, the spice bottle 12 includes a bottle body 122 and a bottle cap 121, the bottle body 122 is at least partially located in the accommodating cavity, the air hole 12a is provided on the bottle body 122 and communicates with the accommodating cavity, and the bottle cap 121 is provided outside the accommodating cavity and is detachably provided at the opening of the bottle body 122. In this way, when the spices in the spice bottle 12 are exhausted, the user can open the bottle cap 121 to replace or replenish the spices in the spice bottle 12. It is worth noting that in one embodiment, the bottle body 122 can be completely located in the accommodating cavity, at which time the bottle cap 121 is connected to the bottle body 122 through the through hole on the top plate 131, and the bottle cap 121 can be completely located outside the accommodating cavity or partially located outside the accommodating cavity. In another embodiment, only a part of the bottle body 122 is located in the accommodating cavity, and a part of it extends out through the through hole on the top plate 131. It is worth noting that the air hole 12a should be connected to the accommodating cavity, that is, the air hole 12a is arranged at the portion of the bottle body 122 located in the accommodating cavity.

[0049] See also Figure 5In an optional embodiment, the air holes 12a are arranged in an array. Furthermore, the body 122 of the spice bottle 12 is cylindrical, and the multiple air holes 12a arranged in an array are distributed on the cylindrical body 122. Such an arrangement is conducive to sufficient gas exchange between the air flow flowing in from the air inlet 11a and the spices in the spice bottle 12 during the process of passing through the spice bottle 12. The air flow flowing out from the air outlet 11b carries sufficient fragrance to meet user needs. Optionally, the spices in the spice bottle 12 may be solid spices. Array, or matrix, means a rectangular array, arranged side by side in the form of an array. Such an arrangement makes the spice slot have the advantage of easy processing. At the same time, such an arrangement is conducive to sufficient air flow exchange, so that the air flow passing through the spice slot carries sufficient fragrance to meet user needs.

[0050] See also Figure 6 In an optional embodiment, the driving assembly 14 includes a sheave intermittent motion mechanism and a motor 143, and the sheave intermittent motion mechanism includes an active sheave 141 and a passive sheave 142, wherein the active sheave 141 is connected to the motor 143 and the passive sheave 142, and the passive sheave 142 is connected to the switching member 13. The sheave intermittent motion mechanism can accurately control the angle of rotation. In an embodiment, the number of the spice bottles 12 is 4, that is, the number of the corresponding accommodating grooves is also 4. When it is necessary to switch the accommodating cavity connected to the air inlet 11a and the air outlet 11b, it is necessary to accurately control the angle of rotation of the switching member 13 to 90 degrees or a multiple of 90 degrees. The sheave intermittent motion mechanism meets the requirement of accurately controlling the angle of rotation. Specifically, the angle of rotation of the passive sheave 142 can be controlled by controlling the number of grooves of the passive sheave 142. In an optional embodiment, the passive sheave 142 is provided with 4 grooves, and the active sheave 141 rotates one circle, driving the passive sheave 142 to rotate 90 degrees. In one embodiment, the number of the spice bottles 12 is N, the number of the accommodating cavities and the number of grooves of the passive groove wheel 142 are both N, the active groove wheel 141 rotates 1 circle, and the passive groove wheel 142 rotates 360° / N. In addition, the groove wheel intermittent motion mechanism also has the advantages of simple structure, easy processing, reliable operation, and high mechanical efficiency. Compared with the ratchet mechanism, the groove wheel mechanism moves more smoothly when entering and disengaging. In addition, the groove wheel intermittent motion mechanism has lower control requirements for the motor 143, and the precise control of the angle by the drive component 14 is achieved by the structural design of the groove wheel, rather than relying on the precise control of the motor 143. Therefore, the use of the groove wheel intermittent motion mechanism can also greatly reduce the manufacturing cost of the spice device 10.

[0051] Optionally, the passive sheave 142 is provided with N radial grooves, and the number of the radial grooves and the number of the accommodating cavities are set correspondingly. When the active sheave 141 rotates one circle, the passive sheave 142 rotates 1 / N circle. Optionally, N can be 4. The sheave intermittent motion mechanism is an outer sheave motion mechanism. For the outer sheave mechanism, the active sheave 141 is provided with a round pin, and the passive sheave 142 is provided with a plurality of radial grooves for the round pin to move. To avoid axial force, the groove of the passive sheave 142 is generally provided in the radial direction of the passive sheave 142. In addition, the active sheave 141 is provided with an outer convex locking arc, and the passive sheave 142 is provided with an inner concave locking arc. When the motor 143 drives the active sheave 141 to rotate continuously, the round pin has not yet entered the groove of the passive sheave 142, and the outer convex locking arc on the active sheave 141 clamps the inner concave locking arc on the passive sheave 142, and the passive sheave 142 does not rotate at this time. When the round pin enters the groove, the inner concave locking arc on the passive groove wheel 142 is separated from the outer convex locking arc, so that the passive groove wheel 142 is driven to rotate. When the round pin leaves the radial groove locking arc from the other side and is stuck again, the passive groove wheel 142 stops moving until the round pin enters another groove again. Thus, intermittent motion and precise angle control are achieved.

[0052] See also Figure 7 , Figure 8 , Fig. 9 In an optional embodiment, the fragrance device 10 further includes a housing and a fixing member, the motor 143 and the groove wheel intermittent motion mechanism are both arranged in the housing, and the housing and the base 11 are both provided with fixing holes, and the fixing member is used to pass through the fixing hole to fix the housing and the base 11. For aesthetics and to prevent damage to the driving mechanism. The fragrance device 10 also includes a housing for protecting the driving assembly 14. Specifically, the housing includes a first housing 144a and a second housing 144b. The first housing 144a and the bottom of the base 11 together form a cavity, and the groove wheel intermittent motion mechanism is arranged in the cavity. The motor 143 is arranged in the cavity formed by the second housing 144b and the first housing 144a. In one embodiment, a convex ridge is formed on the side of the base 11, and a fixing hole that passes through the cam. The limiting ring 15, the first housing 144a, and the second housing 144b are all provided with fixing holes corresponding to one or more of them. During the assembly process of the fragrance device 10, the connection between the base 11 and the first shell 144a, the connection between the first shell 144a and the second shell 144b, and the connection between the limiting ring 15 and the base 11 are all achieved through fixing members.

[0053] See also Figure 2In an optional embodiment, the number of the spice bottles 12 is not less than 2 and not more than 10. Under the premise that the spice device 10 includes a plurality of spice bottles 12, the number of the spice bottles 12 is controlled between 2 and 10, so as to provide users with a variety of aroma types to choose from. The structure of the spice device 10 is simplified and the manufacturing cost is reduced. It is worth noting that in the spice device 10 proposed in the present invention, the number of spice bottles 12 corresponds to the number of the accommodating chambers and the number of grooves opened on the passive groove wheel 142. In one embodiment, the number of the spice bottles 12, the accommodating chambers, and the number of grooves are all 4.

[0054] Please refer to Fig.10 The present invention also proposes an air conditioner 100, which includes the fragrance device 10 described above. Specifically, the fragrance device 10 can emit fragrance into the room according to the needs of the user, so as to increase the indoor aroma, thereby enhancing the user's sense of pleasure or eliminating odor.
