Description

Fragrance device

The present disclosure relates to a fragrance device, and in particular to a fragrance device suitable for use in automobiles.

Due to the structural problems of the air duct or the housing with the fragrance in the general car fragrance device, the flexibility of the use of the existing fragrance device is very limited, so that the operation of the existing fragrance device still has many problems and deficiencies, such as sharing the air duct with the car air-conditioning system to cause fragrance residue and the housing with the fragrance cannot be used for fragrance mixing.

In view of the above, the present disclosure proposes a fragrance device to improve the problems in the prior art that the air duct is shared with the automobile air-conditioning system, resulting in residual fragrance and that the casing with fragrance cannot mix the fragrance.

According to an aspect of the present disclosure, a fragrance device is provided, which includes an air supply element, a first housing, a second housing, a first fragrance component and a second fragrance component. The airflow supply part is used for providing airflow. The first housing has a first port and a second port. The first port is connected to the air supply part. The first fragrance component includes at least two first fragrance supply parts and at least one first switch part. The first switch part is arranged on the first housing and Between at least two first fragrance supply parts, the fragrance materials of these first fragrance supply parts are selectively released into the first housing, so that the fragrance materials of these first fragrance supply parts flow out from the second port through the airflow. The second case is arranged side by side with the first case and has a third port and a fourth port. The third port is connected to the air supply part. The second port is connected to the second casing. The second fragrance component includes at least two second fragrance supply parts and at least one second switch part. The second switch part is arranged between the second casing and at least two second fragrance supply parts to selectively release the fragrance materials of the second fragrance supply parts into the second casing, wherein the fragrance material of the first fragrance supply part, the fragrance material of the second fragrance supply part or a combination thereof flowing out from the second opening flow out from the fourth passage through the airflow.

Based on the above, by using the first or the second switch to control whether the first or the second fragrance supply is released or not, the quantity of the fragrance supply to be mixed can be flexibly selected. In this way, only the fragrance of a single fragrance supply part can be released, or the fragrances of a plurality of fragrance supply parts can be mixed through the housing. Moreover, through the design of the air supply parts independent of the car air-conditioning system, it is possible to avoid sharing the air duct and causing fragrance residue in the car air-conditioning system.

In order to make the above-mentioned features and advantages of the present disclosure more comprehensible, the following specific embodiments are described in detail together with the accompanying drawings.

Moreover, the types of fragrances contained in these second fragrance supply parts 131 are different from the types of fragrances contained in the aforementioned two first fragrance supply parts 121, that is, the four correspond to different fragrances. taste. The second switch element is disposed between the second casing 130 and at least two second aroma supply elements 131 . The second switch part can switch the second aroma supply part 131 into a release state or a closed state. The second switch part is used to selectively release the fragrance materials of the second fragrance supply parts 131 into the second casing 130, so that the airflow provided by the airflow supply part 110 can mix the fragrance materials of the second fragrance supply parts 131 and flow to the fourth port 130E2 when passing through the second casing 130. For example, the aroma device 100 may further include a controller (not shown in the figure), the controller may be electrically connected to the second switch element and used to control the second switch element to selectively release the fragrance of the second aroma supply elements 131 into the second casing 130 . Therefore, the fragrance material of the first fragrance supply part 121 , the fragrance material of the second fragrance supply part 131 or a combination thereof flowing out from the second port 120E2 can all flow out from the fourth port 130E2 through the airflow.

Regarding the further implementation details of the switching device described in this disclosure, the following second embodiment is provided for detailed description. Please refer to Figures 2A, 2B and 3. Figures 2A and 2B show a perspective view of a fragrance device 200 according to a second embodiment of the present disclosure, and Figure 3 shows a side perspective view of the fragrance device 200. The second embodiment is an illustration of a fragrance device with three housings to illustrate further implementation details of the present disclosure.

The fragrance device 200 proposed in the second embodiment of the present disclosure can be applied in the automotive field, ie, as a car fragrance device. The fragrance device 200 may include an airflow supply part 210, three fragrance components and three independent housings. The three independent casings can be the first casing 220 , the second casing 230 and the third casing 240 , and the three fragrance components can be the first fragrance component, the second fragrance component and the third fragrance component. The airflow supply part 210 is the same as the airflow supply part 110 of the first embodiment, and the airflow supply part 210 is not added here. to repeat.

As shown in FIGS. 2A and 2B , the first casing 220 , the second casing 230 and the third casing 240 are arranged side by side, and all of them can be hollow casings. The first housing 220 , the second housing 230 and the third housing 240 are arranged side by side along a longitudinal direction (parallel to the Z axis). That is, the second casing 230 is stacked on the third casing 240 , the first casing 220 is stacked on the second casing 230 , and the three casings are stacked. The length dimensions of the first housing 220 , the second housing 230 and the third housing 240 may be, but not limited to, different from each other. In this embodiment, the third housing 240 is the longest, the second housing 230 is next, and the first housing 220 is the shortest. That is, the lengths of the three housings are tapered from the bottom to the top of the fragrance device 200 .

As shown in FIG. 3 , both ends of the first housing 220 have a first port 220E1 and a second port 220E2 . The first port 220E1 communicates with the second port 220E2 and can be regarded as a fragrance channel. The first port 220E1 is connected to the casing 210 to introduce the airflow provided by the airflow supply part 210 into the first casing 220 . Similarly, both ends of the second housing 230 have a third port 230E1 and a fourth port 230E2 . The third port 230E1 communicates with the fourth port 230E2 and can be regarded as a fragrance channel. Both ends of the third housing 240 have a fifth port 240E1 and a sixth port 240E2 . The fifth port 240E1 communicates with the sixth port 240E2 and can be regarded as a fragrance channel. The third port 230E1 and the fifth port 240E1 are connected to the air supply part 210 to introduce the air flow provided by the air supply part 210 into the second housing 230 and the third housing 240 respectively.

As shown in Figure 3, the second housing 230 and the third housing 240 can also Each includes a connection port 230H and a connection port 240H. The second port 220E2 is opened at the bottom of the first housing 220 along the longitudinal direction (parallel to the Z axis) and connected to the connection port 230H of the second housing 230 . Similarly, the fourth port 230E2 is opened at the bottom of the second housing 230 along the longitudinal direction (parallel to the Z-axis) and connected to the connection port 240H of the third housing 240 . The sixth port 240E2 located at the bottom is opened towards the left (parallel to the Y axis) to communicate with the external environment of the fragrance device 200 .

Please refer to FIG. 4A and FIG. 4B . FIG. 4A and FIG. 4B are top perspective views of the airflow supply member 210 and the first casing 220 included in the fragrance device 200 , so as to illustrate the internal configuration of the first casing 220 . 4A corresponds to the situation where the airflow supply part 210 is not turned on, and Fig. 4B corresponds to the situation where the airflow supply part 210 is turned on.

As shown in Figures 4A and 4B, the first fragrance component includes at least two first fragrance supply parts 221 and at least one first switch part, such as the two first switch parts 222 shown in this embodiment. For example, the shape of the first aroma supply parts 221 can be, but not limited to, substantially square as shown in FIGS. 2A and 2B , and are disposed on two side portions of the first housing 220 opposite to each other. In addition, the types of fragrances contained in the first fragrance supply parts 221 can be different, that is, the two correspond to different fragrances. The first switch part 222 can be but not limited to a valve, which can switch the first aroma supply part 221 to a release state or a closed state. The first switch part 222 is used to selectively release the fragrance materials of the first fragrance supply parts 221 into the first casing 220, so that the fragrance materials of the first fragrance supply parts 221 can be mixed when the airflow provided by the airflow supply part 210 passes through the first casing 220, so that the fragrance materials of the first fragrance supply parts 221 are passed through the second port by the airflow. 220E2 outflow. For example, the fragrance device 200 may further include a controller (not shown in the figure), the controller is electrically connected to the first switch part 222 and used to control the first switch part 222 to selectively release the fragrance materials of the first fragrance supply parts 221 into the first casing 220.

That is to say, the first housing 220 provides four possible fragrance supply states: (i) the first switch part 222 releases the first type of fragrance contained in a first fragrance supply part 221, but does not release the second type of fragrance contained in the other first fragrance supply part 221; The first type of fragrance contained in a first fragrance supply part 221 also releases the second type of fragrance contained in another first fragrance supply part 221;

As shown in FIGS. 4A and 4B , the fragrance device 200 may further include a first non-return member 251, such as a non-return valve or a non-return structure with valves, which is disposed in the first housing 220 and adjacent to the second port 220E2. Specifically, the first backstop member 251 is also disposed between the first aroma supply member 221 and the second through opening 220E2 along the Y-axis. Correspondingly, when the airflow supply member 210 is opened to provide airflow, the first check member 251 can be opened along the supply direction of the airflow to form the opening OP as shown in FIG. 4B . That is, the first backstop 251 is limited to only move from the first port 220E1 to the second port when the air flow supply part 210 provides air flow. The direction of 220E2 (corresponding to the supply direction of the air flow) is opened, thereby providing an air flow channel and preventing the air flow from being reversed.

To sum up the above, when the first switch member 222 releases the first type of fragrance contained in the first fragrance supply part 221 and/or the second type of fragrance contained in another first fragrance supply part 221, the airflow provided by the airflow supply part 210 will first blow the first fragrance supply part 221 in the space _V1 partitioned by the first backstop part 251 in the first housing 220 to take away the aroma molecules of the first type of fragrance and/or the second type of fragrance, and then pass through the opening of the first backstop 251 OP flows out from the second port 220E2. Due to the design that the second port 220E2 is connected to the second housing 230 , the airflow flowing out from the second port 220E2 can finally enter the second housing 230 .

Please refer to Figures 5A and 5B. Figures 5A-5B show the top perspective views of the airflow supply part 210 and the second housing 230 included in the fragrance device 200, in order to illustrate the internal configuration of the second housing 230. Figure 5A corresponds to the situation where the airflow supply part 210 is not opened, and Figure 5B corresponds to the situation when the airflow supply part 210 is opened.

As shown in Figures 5A and 5B, the second fragrance component includes at least two second fragrance supply parts 231 and at least one second switch part, such as the two second switch parts 232 shown in this embodiment. For example, the shape of the second aroma supply parts 231 can be, but not limited to, substantially square as shown in FIGS. 2A and 2B , and are disposed on two side portions of the second casing 230 opposite to each other. In addition, the types of fragrances contained in the second fragrance supply parts 231 are different, that is, the two correspond to different fragrances. And, the type of the aromatic material contained in these second fragrance supply parts 231 is different from the aforementioned two first fragrance supply parts. The types of aromatic materials contained in 221 are different from each other, that is, the four correspond to different fragrances.

The second switch member 232 can be, but not limited to, a valve, which can switch the second aroma supply member 231 into a release state or a closed state. The second switch part 232 is used to selectively release the fragrance materials of the second fragrance supply parts 231 into the second casing 230, so that the airflow provided by the airflow supply part 210 can mix the fragrance materials of the second fragrance supply parts 231 and flow to the fourth port 230E2 when passing through the second casing 230. For example, the fragrance device 200 may further include a controller (not shown in the figure), which can be electrically connected to the second switch part 232 and used to control the second switch part 232 to selectively release the fragrance materials of the second fragrance supply parts 231 into the second casing 230 .

That is to say, the second casing 230 also provides four possible fragrance supply states: (i) the second switch part 232 releases the third type of fragrance contained in the second fragrance supply part 231, but does not release the fourth type of fragrance contained in the other second fragrance supply part 231; The third type of fragrance contained in a second fragrance supply part 231 is released, and the fourth type of fragrance contained in another second fragrance supply part 231 is released;

As shown in Figures 5A and 5B, the fragrance device 200 may further include a second check member 252, such as a check valve or a check valve with a flap. structure, which is disposed in the second casing 230 and adjacent to the fourth port 230E2. Specifically, the second backstop member 252 is also disposed between the second aroma supply member 231 and the fourth through port 230E2 along the Y-axis. Correspondingly, when the airflow supply member 210 is opened to provide airflow, the second check member 252 can open/form the opening OP along the supply direction of the airflow as shown in FIG. 5B . That is, the second check member 252 is restricted to open only in the direction from the third port 230E1 to the fourth port 230E2 (corresponding to the supply direction of the air flow) when the air flow supply member 210 provides the air flow, thereby providing an air flow passage and preventing the reverse flow of the air flow.

To sum up the above, when the second switch member 232 releases the third type of fragrance contained in a second fragrance supply part 231 and/or the fourth type of fragrance contained in another second fragrance supply part 231, the airflow provided by the airflow supply part 210 will first blow the second fragrance supply part 231 in the space _V2 partitioned by the second backstop part 252 in the second housing 230 to take away the aroma molecules of the third type of fragrance and/or the fourth type of fragrance, and then pass through the opening of the second backstop 252 The OP is mixed with the airflow flowing down the longitudinal direction from the second port 220E2 , and then flows to the fourth port 230E2 . Therefore, the fragrance material of the first fragrance supply part 221 , the fragrance material of the second fragrance supply part 231 or a combination thereof flowing out from the second port 220E2 can all flow out from the fourth port 230E2 through the airflow. Due to the design that the fourth port 230E2 is connected to the third housing 240 , the airflow flowing out from the fourth port 230E2 can finally flow into the third housing 240 .

Please refer to Figures 6A and 6B. Figures 6A and 6B show top perspective views of the airflow supply part 210 and the third housing 240 included in the fragrance device 200, in order to illustrate the internal configuration of the third housing 240. Among them, Figure 6A corresponds to the airflow supply. When the element 210 is not turned on, FIG. 6B corresponds to the situation that the airflow supply element 210 is turned on.

As shown in Figures 6A and 6B, the third fragrance component includes at least two third fragrance supply parts 241 and at least one third switch part, such as the two third switch parts 242 shown in this embodiment. For example, the shape of the third fragrance supply parts 241 can be, but not limited to, substantially square as shown in FIGS. 2A and 2B , and they are disposed on two sides of the third casing 240 opposite to each other. In addition, the types of fragrances contained in the third fragrance supply parts 241 are different, that is, the two correspond to different fragrances. And, the kind of the aromatic materials contained in these third fragrance supply parts 241 is different from the fragrance materials contained in the aforementioned two first fragrance supply parts 221 and the types of the fragrance materials contained in the aforementioned two second fragrance supply parts 231, that is, the six correspond to different fragrances. The third switch member 242 can be, but not limited to, a valve, which can switch the third fragrance supply member 241 between a released state and a closed state. The third switch part 242 is used to selectively release the fragrance materials of the third fragrance supply parts 241 into the third casing 240, so that when the airflow provided by the airflow supply part 210 passes through the third casing 240, it can mix the fragrance materials of the third fragrance supply parts 241 and flow to the sixth port 240E2.

That is to say, the third housing 240 also provides four possible fragrance supply states: (i) the third switch part 242 releases the fifth type of fragrance contained in a third fragrance supply part 241, but does not release the sixth type of fragrance contained in another third fragrance supply part 241; A third aroma supply part 241 contained in the first Five types of fragrance materials, and also release the sixth type of fragrance materials contained in another third fragrance supply part 241;

In this embodiment, the two first switch parts 222 respectively correspond to the two oppositely arranged first fragrance supply parts 221, the two second switch parts 232 respectively correspond to the two oppositely arranged second fragrance supply parts 231, and the two third switch parts 242 respectively correspond to the two opposite third fragrance supply parts 241 for illustration. However, the present disclosure is not limited thereto. In another embodiment, when the two first fragrance supply parts are arranged adjacently, the two second fragrance supply parts are adjacently arranged, and the two third fragrance supply parts are adjacently arranged, a single first switch part, a single second switch part, and a single third switch part can respectively control whether the fragrance materials of the two first fragrance supply parts, the fragrance materials of the two second fragrance supply parts, and the fragrance materials of the two third fragrance supply parts are released or not.

As shown in FIGS. 6A and 6B , the fragrance device 100 may further include a third check member 253 . The third check member 253 is, for example, a check valve or a check structure with a valve plate, which is disposed in the third housing 240 and adjacent to the sixth port 240E2 . Specifically, the third backstop member 253 is also disposed between the third fragrance supply member 241 and the sixth through port 240E2 along the Y-axis. Corresponding to when the airflow supply member 210 is opened to provide airflow, the third check member 253 can open/form the opening OP along the supply direction of the airflow as shown in FIG. 6B . That is, the third backstop 253 is limited to only move along the direction from the fifth port 240E1 to the sixth port when the air flow supply part 210 provides air flow. The direction of 240E2 (corresponding to the supply direction of the air flow) is opened, thereby providing an air flow channel and preventing the air flow from being reversed.

To summarize the above, when the third switch member 242 releases the fifth type of fragrance contained in a third fragrance supply part 241 and/or the sixth type of fragrance contained in another third fragrance supply part 241, the airflow provided by the airflow supply part 210 will first blow the third fragrance supply part 241 in the space _V3 partitioned by the third backstop part 253 in the third housing 240 to take away the aroma molecules of the fifth type of fragrance and/or the sixth type of fragrance, and then pass through the opening of the third backstop 253 The OP is mixed with the airflow flowing down the longitudinal direction from the fourth port 230E2, and then flows to the sixth port 240E2. Therefore, the fragrance material of the first fragrance supply part 221 flowing out from the second port 220E2 , the fragrance material of the second fragrance supply part 231 flowing out from the fourth port 230E2 , the fragrance material of the third fragrance supply part 241 or a combination thereof can all flow out from the sixth port 240E2 by airflow. Since the sixth port 240E2 is connected to the external environment of the fragrance device 200, the airflow flowing out from the sixth port 240E2 can eventually diffuse to the outside world, such as the interior space of a car to provide fragrance. Wherein, the airflow finally flowing out from the sixth port 240E2 to the outside gathers the airflows from the first housing 220 , the second housing 230 and the third housing 240 to provide various mixed/single aromas. Specifically, the fragrance device 200 in this embodiment can provide 63 kinds of fragrances with different fragrances.

In addition, as shown in FIG. 3, the second port 220E2 and the second check member 252 are arranged in a misaligned position in the air supply direction (parallel to the Y-axis, from right to left in the figure), and the second port 220E2 is opened at a position farther away from the air supply member 210 than the second check member 252 along the air supply direction. Referring to FIG. 3 , the opening position of the second port 220E2 is more to the left than the position of the second backstop member 252 . This design can achieve that the airflow flowing out from the second port 220E2 only mixes with the airflow passing through the second backstop 252 in the area behind the second backstop 252 and does not enter the space V ₂ before the second backstop 252 . Therefore, the fragrance of the first type of fragrance or the second type of fragrance cannot remain in the space V ₂ , thereby avoiding affecting the fragrance mixing mechanism of each shell itself.

Similarly, as shown in FIG. 3 , the fourth port 230E2 and the third backstop 253 are also arranged in a misaligned position in the supply direction of the airflow (parallel to the Y axis, from right to left in the figure), and the fourth port 230E2 is opened at a position farther away from the airflow supply part 210 than the third backstop 253 along the supply direction of the airflow.

Similarly, this design can achieve that the airflow flowing out from the fourth port 230E2 only mixes with the airflow passing through the third backstop 253 in the area behind the third backstop 253 and does not enter the space V ₃ before the third backstop 253 . Therefore, the fragrance of the first type of fragrance, the second type of fragrance, the third type of fragrance or the fourth type of fragrance cannot remain in the space V ₃ , so as to avoid affecting the fragrance mixing mechanism of each shell itself.

As shown in FIG. 3 , the second port 220E2 and the fourth port 230E2 are staggered in the air supply direction (parallel to the Y-axis, from right to left in the figure). Specifically, the fourth port 230E2 is opened at a position farther away from the air supply member 210 than the second port 220E2 along the air supply direction. Referring to FIG. 3 , the opening position of the fourth port 230E2 is more leftward than the opening position of the second port 220E2 . This design can achieve the airflow flowing out from the second port 220E2 and pass through the second reverse The airflow of the stopper 252 has a certain distance to be fully mixed to make the aroma more evenly mixed, and then flows out from the fourth port 230E2.

Similarly, as shown in FIG. 3 , the fourth port 230E2 and the sixth port 240E2 are also misaligned in the air supply direction (parallel to the Y-axis, from right to left in the figure). Specifically, the sixth port 240E2 is opened at a position farther away from the air supply member 210 than the fourth port 230E2 along the air supply direction. Referring to FIG. 3 , that is, the opening position of the sixth port 240E2 is more to the left than the opening position of the fourth port 230E2 . This design can achieve that the airflow flowing out from the fourth port 230E2 and the airflow passing through the third backstop 253 have a certain distance to fully mix to make the mixing of aroma more uniform, and then flow out from the sixth port 240E2.

In this embodiment, as shown in FIG. 3 , if the distance from the airflow supply part 210 in the airflow supply direction (parallel to the Y axis, from right to left in the figure) is taken as a reference, the dislocation arrangement from close to to far away from the airflow supply part 210 is the first backstop part 251, the second backstop part 252, the second port 220E2, the third backstop part 253, the fourth port 230E2, and the sixth port 240E2.

In addition, please refer back to FIGS. 3 , 4A and 4B , the fragrance device 200 may further include a first flow guide 261 , a second flow guide 262 and a third flow guide 263 . The first air guiding element 261 is disposed in the first casing 220 and adjacent to the first aroma supply elements 221 . The second air guide 262 is disposed in the second casing 230 and adjacent to the second aroma supply members 231 . The third air guide 263 is disposed in the third housing 240 and adjacent to the third fragrance supplying parts 241 .

The first air guide 261 , the second air guide 262 and the third air guide 263 are used to guide the airflow provided by the airflow supply part 210 to mix the aromatic material in the spaces V ₁ , V ₂ and V ₃ respectively and flow to the corresponding second port 220E2 , fourth port 230E2 and sixth port 240E2 . Therefore, the function of the first air guiding element 261 , the second air guiding element 262 and the third air guiding element 263 is to prevent the airflow from flowing back to the air supply element 210 or its corresponding first aroma supply element 221 , second aroma element 231 and third aroma element 241 .

In summary, by using the switch to control whether the aroma supply is released or not, the number of aroma supply elements to be mixed can be flexibly selected. In this way, only the fragrance of a single fragrance supplier can be released, or the fragrances of a plurality of fragrance suppliers can be mixed through the housing. Moreover, through the design of the position between the openings and the backstop and the flow guide, the fragrance supply parts of different housings will not contaminate each other and the effect of avoiding the reverse flow of the airflow can be achieved.
