Description

Technical Field

[0001] This application relates to the technical field of fragrance, and particularly to a multi-flavor fragrance system. Background Art

[0002] The fragrance system can be used in vehicles. When the user turns on the switch of the fragrance system, the fragrance system starts and volatilizes the fragrance. As the fragrance volatilizes, the fragrance molecules diffuse in the air. At this time, the fragrance system can release the fragrance through a fan and circulate it into the vehicle through the ventilation duct of the vehicle. To meet the needs of more fragrances, the number of fragrances of the fragrance system can be set to multiple. The existing fragrance system can evenly distribute the fragrance generating devices circumferentially to arrange more fragrance odors in a limited space. Usually, this arrangement method can arrange more than three fragrances. In this fragrance system, its multiple fragrance generating devices are usually arranged on a rotating structure. When the rotating structure rotates, it drives the multiple fragrance generating devices to rotate synchronously to connect different fragrance devices with the air flow channel so that the fragrance can be released, thereby realizing the switching of fragrances. However, after the multiple fragrance generating devices of this fragrance system rotate, their circumferential positions change. Since the number of fragrance generating devices is relatively large, during the process of adding, replacing, etc. of the fragrance, it often involves re-identifying and recognizing the circumferential positions of multiple fragrance generating devices, which is inconvenient.

[0028] The embodiment of the present application provides a multi-flavor fragrance system, and the multi-flavor fragrance system includes:

[0029] A fragrance housing 100 is provided with a first chamber 110 and a second chamber 120. The first chamber 110 communicates with the second chamber 120. The fragrance housing 100 has an air inlet 130 and a release port 140. The air inlet 130 communicates with the first chamber 110, and the release port 140 communicates with the second chamber 120;

[0030] A plurality of fragrance generating devices 200 are provided. The plurality of fragrance generating devices 200 are arranged circumferentially in the second chamber 120;

[0031] A fan 300 is connected to the fragrance housing 100 and is arranged in the first chamber 110. The fan 300 sends air flow from the air inlet 130 into the first chamber 110 and the second chamber 120 in sequence, and sends the air flow out from the release port 140 after passing through the fragrance generating device 200;

[0032] A fragrance switching device 400 includes a switching drum 410. The switching drum 410 is rotatably arranged in the second chamber 120 and includes an inner drum layer 411 and an outer drum layer 412. A plurality of fragrance generating devices 200 are all arranged between the inner drum layer 411 and the outer drum layer 412. A set of fragrance excitation inlets 413 and fragrance excitation outlets 414 are arranged on the inner drum layer 411 and the outer drum layer 412. The switching drum 410 rotates to arrange the fragrance excitation inlets 413 and the fragrance excitation outlets 414 on both sides of any one of the fragrance generating devices 200.

[0033] As Figure 1 and Figure 2 shown, in this embodiment, by way of example, the fragrance housing 100 serves as a protective component outside the system. Its overall structure can be set to a similar cylindrical shape, and specifically, it can be made of materials such as metal, plastic, and glass. During specific implementation, it is selected according to actual needs, and an appropriate process is selected to form it, which is not limited here. The first chamber 110 can be arranged in the middle position of the fragrance housing 100, and it can be set to a cylindrical shape. The second chamber 120 can be arranged on the outer edge of the first chamber 110, and the second chamber 120 and the first chamber 110 can be separated by the internal structure of the fragrance housing 100. At the separation between the second chamber 120 and the first chamber 110, the two can communicate through a through hole 150. The air inlet 130 can be arranged on one end of the fragrance housing 100 to facilitate its communication with the first chamber 110; the air inlet 130 can be set as a plurality of uniformly distributed round holes, and it can be arranged in a circumferential array or other arrangement methods. The release port 140 can be arranged on the side of the fragrance housing 100 to facilitate its communication with the second chamber 120; the release port 140 can also adopt a structure similar to that of the air inlet 130, and it can be arranged in a rectangular array or other arrangement methods.

[0034] AsFigure 1 and Figure 2 As shown in Figure 2 and , the fragrance generating device 200 may include a fragrance carrier 210 and a fragrance. The fragrance carrier 210 is used to arrange the fragrance and may be set as a rod-shaped container. One end of the fragrance carrier 210 may be set as a detachable cap, and the detachable manner may be snap connection, screw connection, etc., so as to facilitate the addition, replacement, etc. of the fragrance. The side surface of the fragrance carrier 210 may be evenly distributed with air holes; when the fragrance is arranged in the fragrance carrier 210, air can be blown into the fragrance carrier 210 through the air holes to stimulate the fragrance smell of the fragrance. The fragrance generating device 200 is arranged in the second chamber 120, and a plurality of them are arranged at equal intervals in the circumferential direction, and the fragrances of the plurality of fragrance generating devices 200 may also be set as several types. For example, in this embodiment, the fragrance generating device 200 is set as 12; at the same time, the fragrances of the 12 fragrance generating devices 200 are different, that is, 12 types.

[0035] Of course, in some embodiments, the number of the fragrance generating devices 200 may also be other numbers, such as 8, 9, 10, etc. And in some other embodiments, the fragrances of the plurality of fragrance generating devices 200 may also be repeated. For example, when the number of the fragrance generating devices 200 is 8, the fragrances may be only 6, 7, etc.

[0036] As Figure 1 and Figure 2 shown in Figure 1 and Figure 2 , the air flow for stimulating the fragrance may be driven by the fan 300. The fan 300 may be arranged on the fragrance housing 100, and is specifically arranged in the first chamber 110. When the fan 300 operates, the air flow outside the system enters from the air inlet 130 under the action of the pressure difference and flows through the first chamber 110 and the second chamber 120 in sequence. In the second chamber 120, the air flow stimulates the fragrance inside through the air holes on the fragrance carrier 210, and the fragrance is discharged from the release port 140 along with the air flow after being stimulated. The fan 300 may also be provided with gears, and different gears correspond to different air flow sizes; and by controlling the gears of the fan 300, the adjustment of the fragrance concentration can be realized. Further, a guiding structure 500 may be arranged on the side surface of the fragrance housing 100 near the release port 140; when the multi-flavor fragrance system is used in a vehicle, the air flow containing the fragrance discharged from the release port 140 can be guided by the guiding structure 500 and then circulated into the vehicle through the ventilation duct of the vehicle. Of course, the multi-flavor fragrance system can be applied to other usage environments, such as bedrooms, lockers, etc.

[0037] As Figure 1 and Figure 2As shown, when the fragrance needs to be switched, it can be done through the fragrance switching device 400. The switching drum 410 of the fragrance switching device 400 can be arranged in the second chamber 120, and the inner layer 411 of the drum and the outer layer 412 of the drum can be coaxially arranged; at the same time, the inner layer 411 of the drum is connected to the outer layer 412 of the drum, and it can be prepared in an integrated manner. The 12 fragrance generating devices 200 in this embodiment can be arranged in a circular array between the inner layer 411 of the drum and the outer layer 412 of the drum, and the inner layer 411 of the drum is provided with a fragrance excitation inlet 413, and the outer layer 412 of the drum is provided with a fragrance excitation outlet 414. The number of the fragrance excitation inlet 413 and the fragrance excitation outlet 414 are both set to one, and the two can be set at the same radial position. When the switching drum 410 rotates, it can arrange the fragrance excitation inlet 413 and the fragrance excitation outlet 414 arranged in groups on both sides of any fragrance generating device 200. When the airflow enters the second chamber 120 from the first chamber 110, it enters between the drum inner layer 411 and the drum outer layer 412 from the fragrance excitation inlet 413, passes through the corresponding fragrance generating device 200 to excite the fragrance of the fragrance generating device 200, then passes through the fragrance excitation outlet 414, and then is discharged from the release port 140. When it is necessary to switch the fragrance, the switching drum 410 is driven to rotate so that the fragrance excitation inlet 413 and the fragrance excitation outlet 414 arranged in groups are distributed on both sides of another fragrance generating device 200.

[0038] It can be understood that the present application provides a rotatable switching drum 410; at the same time, by reasonably setting the position and structure of the switching drum 410, in detail, a plurality of fragrance generating devices 200 are arranged between the inner drum layer 411 and the outer drum layer 412 of the switching drum 410, and at the same time, a group of fragrance excitation inlets 413 and fragrance excitation outlets 414 for stimulating the fragrance of the fragrance generating devices 200 are set in the inner drum layer 411 and the outer drum layer 412; when the fragrance needs to be switched, the switching drum 410 can be driven to rotate so as to distribute the grouped fragrance excitation inlets 413 and fragrance excitation outlets 414 on both sides of the fragrance generating devices 200 at different positions, thereby achieving the purpose of stimulating the fragrance of the fragrance generating devices 200 at different positions through airflow. In the present application, the positions of the plurality of fragrance generating devices 200 are always kept fixed. When the fragrance needs to be added or replaced, there is no need to re-identify and recognize the circumferential positions of the plurality of fragrance generating devices 200, so the operation is more convenient.

[0039] Specifically, the fragrance switching device 400 further includes a rotary drive motor 420 , and the switching drum 410 is driven by the output end of the rotary drive motor 420 .

[0040] like Figure 1And Figure 2 As shown, in this embodiment, by way of example, the rotary drive motor 420 is used to drive the switching drum 410 to rotate, so as to realize the switching of the fragrance; its output end is in transmission with the switching drum 410, and when its output end rotates, the switching drum 410 can be driven to rotate synchronously. The rotary drive motor 420 can be arranged inside the fragrance housing 100, and it can specifically adopt a detachable arrangement method, for example, fixed by bolts and other components. The rotary drive motor 420 can be a stepper motor to improve the control accuracy.

[0041] It can be understood that in this embodiment, by providing the rotary drive motor 420 in transmission with the switching drum 410, it is convenient to realize the automatic switching of the fragrance, which is more convenient.

[0042] More specifically, a gear ring 430 is provided on the switching drum 410, and a gear 440 is provided on the output end of the rotary drive motor 420, and the gear ring 430 meshes with the gear 440.

[0043] As Figure 2 shown, in this embodiment, by way of example, the gear ring 430 can be arranged close to the inner layer 411 of the drum, and can be set as an external gear ring 430, which can be integrally formed with the switching drum 410. The rotary drive motor 420 can be arranged at a position close to the gear ring 430, and its axis is parallel to the axis of the switching drum 410. The gear 440 can be sleeved on the output end of the rotary drive motor 420 and rotates synchronously with the output end of the rotary drive motor 420. The gear ring 430 meshes with the gear 440. When the gear 440 rotates under the drive of the output end of the rotary drive motor 420, the gear 440 can drive the gear ring 430, so as to achieve the purpose of driving the switching drum 410 to rotate.

[0044] Of course, in some embodiments, the gear ring 430 can also be arranged close to the outer layer 412 of the drum, and can be set as an internal gear ring 430, for example, arranged inside the outer layer 412 of the drum. And in other embodiments, when the gear ring 430 is arranged close to the outer layer 412 of the drum, it can of course also be set as an external gear ring 430, for example, arranged outside the outer layer 412 of the drum.

[0045] It can be understood that in this embodiment, a set of mutually cooperating gear ring 430 and gear 440 are used to realize the drive of the rotary drive motor 420 to the switching drum 410, which is convenient to rotate the switching drum 410 in place to realize the accurate switching of the fragrance.

[0046] More specifically, the radius of the gear ring 430 is greater than the radius of the gear 440.

[0047] As Figure 2As shown, in this embodiment, by way of example, when the ring gear 430 meshes with the gear 440, their linear velocities are the same, and the angular velocity of the one with a relatively larger radius is relatively smaller. Therefore, when the radius of the ring gear 430 is relatively large, it has a relatively small angular velocity, that is, a relatively low rotational speed. At this time, the ring gear 430 and the gear 440 form a set of speed reduction structures, which can drive the switching drum 410 at a low rotational speed when driving the switching drum 410 at the output end of the high-speed rotating drive motor 420.

[0048] It can be understood that by reasonably setting the sizes of the ring gear 430 and the gear 440 in this application, the output end of the rotary drive motor 420 can drive the switching drum 410 relatively smoothly, so as to further improve the accuracy of the fragrance during the switching process.

[0049] Specifically, the fragrance housing 100 includes a fragrance mounting bracket 160, and a plurality of fragrance generating devices 200 are arranged on the fragrance mounting bracket 160. The fragrance mounting bracket 160 is inserted between the inner layer 411 and the outer layer 412 of the drum. The multi-scent system further includes a sealing soft pad 600, and the sealing soft pad 600 is arranged between the fragrance mounting bracket 160 and the inner layer 411 and the outer layer 412 of the drum.

[0050] As Figure 2 and Figure 3 shown, in this embodiment, by way of example, the fragrance mounting bracket 160 can be set as an annular structure, which can be coaxially arranged with the switching drum 410 and is arranged between the inner layer 411 and the outer layer 412 of the drum, that is, arranged in the second chamber 120. And the 12 fragrance generating devices 200 in this embodiment can be circumferentially arrayed on the fragrance mounting bracket 160 with the axis of the fragrance mounting bracket 160 as the center, so as to facilitate the fixation of the position in the second chamber 120. The sealing software can be made of rubber material, which is used to fill the gap between the fragrance mounting bracket 160 and the inner layer 411 and the outer layer 412 of the drum. The sealing soft pad 600 is also set as an annular structure, which can be respectively arranged on the outer side of the inner layer 411 and the inner side of the outer layer 412 of the drum. It should be noted that at the positions corresponding to the fragrance excitation inlet 413 and the fragrance excitation outlet 414 on the inner layer 411 and the outer layer 412 of the drum, the sealing soft pad 600 is set as hollowed out to avoid interfering with the flow of air.

[0051] It can be understood that in this embodiment, by setting the fragrance mounting bracket 160 and the sealing soft pad 600, it is not only convenient for a plurality of fragrance generating devices 200 arranged in the second chamber 120 to maintain their positions fixed, but also can improve the airtight effect between the fragrance mounting bracket 160 and the switching drum 410, so as to avoid the fragrance being difficult to be effectively excited due to the random flow of air in the second chamber 120.

[0052] More specifically, limiting bars 415 are provided on both the inner layer 411 and the outer layer 412 of the drum, limiting grooves 610 are provided on the sealing soft pad 600, the limiting bars 415 are arranged in the limiting grooves 610, and the limiting bars 415 and the limiting grooves 610 form a limit in the circumferential direction.

[0053] As Figure 2 and Figure 3 shown, in this embodiment, by way of example, the outer side of the inner layer 411 of the drum can bulge in a direction away from its axis to form the limiting bar 415. When the outer side of the inner layer 411 of the drum is unfolded, the limiting bar 415 can be arranged in a rectangular shape. The limiting bars 415 can be arranged at intervals along the circumferential direction of the inner layer 411 of the drum as several, and the specific number is selected according to actual needs. And the sealing soft pad 600 arranged on the outer side of the inner layer 411 of the drum is correspondingly arranged, that is, the limiting grooves 610 corresponding to the limiting bars 415 are provided. When the sealing soft pad 600 is arranged on the outer side of the inner layer 411 of the drum, the limiting bar 415 is located in the limiting groove 610, and the two form a limit in the axial direction. Similarly, limiting bars 415 can also be provided on the inner side of the outer layer 412 of the drum, and the sealing soft pad 600 arranged on the inner side of the outer layer 412 of the drum is correspondingly arranged to form a limit. When the switching drum 410 rotates under the drive of the output end of the rotary drive motor 420, the sealing soft pads 600 on the inner layer 411 and the outer layer 412 of the drum rotate synchronously with the inner layer 411 and the outer layer 412 of the drum due to the existence of the limiting bars 415 and the limiting grooves 610. It should be noted that in order to make the switching drum 410 rotate smoothly, the friction resistance can also be reduced by means such as applying grease between the sealing soft pad 600 and the inner and outer sides of the fragrance mounting bracket 160.

[0054] It can be understood that in this embodiment, by providing the limiting bars 415 on the inner layer 411 and the outer layer 412 of the drum and providing the limiting grooves 610 on the sealing soft pad 600, the sealing soft pad 600 can be made to rotate synchronously with the switching drum 410 through the cooperation of the limiting bars 415 and the limiting grooves 610, so as to make the sealing soft pad 600 always play a role in improving the airtightness between the switching drum 410 and the fragrance mounting bracket 160.

[0055] Of course, in some embodiments, other fixing methods can also be adopted between the sealing soft pad 600 and the inner layer 411 and the outer layer 412 of the drum, such as fixing through components such as bolts, or injecting and molding the sealing software on the inner layer 411 and the outer layer 412 of the drum, etc.

[0056] Specifically, the fragrance housing 100 is provided with a fragrance chamber 170, and the fragrance chambers 170 correspond one-to-one with the fragrance generating devices 200. The fragrance generating devices 200 are arranged in the fragrance chambers 170. The plurality of fragrance chambers 170 are independent of each other. The switching drum 410 rotates to communicate the fragrance excitation inlet 413 and the fragrance excitation outlet 414 with any one of the fragrance chambers 170.

[0057] As Figure 2 and Figure 4 shown, in this embodiment, by way of example, the fragrance chamber 170 can be arranged on the aforementioned fragrance mounting bracket 160. In this embodiment, 12 independent fragrance chambers 170 can be arranged on the fragrance mounting bracket 160, and the 12 fragrance chambers 170 are not communicated with each other. The 12 fragrance generating devices 200 can be arranged in the 12 fragrance chambers 170 one-to-one. At the same time, the fragrance mounting bracket 160 is further provided with a chamber inlet 171 and a chamber outlet 172 on the side wall of the fragrance chamber 170. The fragrance excitation inlet 413 and the fragrance excitation outlet 414 can be respectively communicated with the chamber inlet 171 and the chamber outlet 172 of any one of the fragrance chambers 170. When the switching drum 410 arranges the fragrance excitation inlet 413 and the fragrance excitation outlet 414 on both sides of any one of the fragrance generating devices 200, the air flow can enter from the fragrance excitation inlet 413, and enter the fragrance chamber 170 from the chamber inlet 171, and then the fragrance can be excited by passing through the fragrance generating device 200. After the excitation, the air flow containing the fragrance can be discharged from the fragrance chamber 170 through the chamber outlet 172 and further discharged from the fragrance excitation outlet 414.

[0058] It can be understood that in this embodiment, by providing the fragrance chambers 170 that correspond one-to-one with the fragrance generating devices 200 and are independent of each other, it is possible to prevent the air flow from surging in the second chamber 120 and causing the fragrances to mix and deteriorate the user experience.

[0059] Specifically, a fragrance core 220 is arranged on the fragrance generating device 200, and the fragrance core 220 is used to identify the information of the fragrance generating device 200.

[0060] As Figure 4 shown, in this embodiment, by way of example, the fragrance core 220 can be arranged at one end of the fragrance carrier 210 opposite to its cap. The fragrance core 220 can be identified by using an IC card (Integrated Circuit Card), or can be identified by using a resistance value. The specific identification method is not limited herein. The fragrance core 220 is used for the system to interact with the vehicle to facilitate the identification of the information of the fragrance generating device 200. The information of the fragrance generating device 200 includes but is not limited to the position, type, remaining amount, etc. of the fragrance.

[0061] It can be understood that by providing the fragrance core 220 in this embodiment, the versatility of the system can be further improved.

[0064] It can be understood that in this embodiment, by providing the housing 800 and arranging the control main board 700 inside the housing 800, the housing 800 can protect the control main board 700, facilitating the control main board 700 to implement its related control functions.

[0065] Specifically, the fragrance housing 100 includes a first housing 180 and a second housing 190. The first housing 180 is connected to the second housing 190, and the first chamber 110 and the second chamber 120 are formed by enclosing the first housing 180 and the second housing 190.

[0066] As Figure 1 and Figure 2As shown, in this embodiment, by way of example, the first housing 180 may include a first plate member 181 and a first pipe member 182. The first plate member 181 may be arranged in a circular shape, and the first pipe member 182 may be arranged as a circular pipe. The first plate member 181 may be arranged at one end of the first pipe member 182 and may be coaxially arranged; the first plate member 181 and the first pipe member 182 may be integrally formed. The second housing 190 may include a second plate member 191 and a second pipe member 192. The second plate member 191 and the second pipe member 192 may be arranged in a structure similar to that of the first plate member 181 and the first pipe member 182, and the radius of the second pipe member 192 is greater than the radius of the first pipe member 182. The first housing 180 and the second housing 190 may be arranged opposite to each other. At this time, the first pipe member 182 may be detachably connected to the second plate member 191 through components such as bolts. When connecting, the first pipe member 182 may be inserted into the second pipe member 192, and one end of the first pipe member 182 away from the first plate member 181 may abut against the second plate member 191, while one end of the second pipe member 192 away from the second plate member 191 may abut against the first plate member 181, so that a first chamber 110 is formed in the inner space of the first pipe member 182, and a second chamber 120 is formed between the outer side of the first pipe member 182 and the inner side of the second pipe member 192.

[0067] As Figure 1 and Figure 2 As shown, in this embodiment, the fragrance installation bracket 160 may be arranged on the first plate member 181 and may be integrally formed with the first plate member 181 and the first pipe member 182. When the fragrance generating device 200 is installed on the fragrance installation bracket 160, it may pass through the first plate member 181 and be arranged in the fragrance chamber 170. The middle position of the first plate member 181 may be recessed into the first pipe member 182 to form an arrangement cavity. The power device of the fan 300 may be arranged in the arrangement cavity, while the fan blades of the fan 300 may be arranged in the first chamber 110, and its power device may pass through the bottom of the arrangement cavity and extend into the first chamber 110 to be connected to its fan blades. A plurality of air inlets 130 may be arranged in a circumferential array on the outer edge of the arrangement cavity; when the fan 300 operates, it may send air flow into the first chamber 110 through the air inlets 130. The cover shell 800 may cover the second plate member 191 and may be detachably connected to the second plate member 191.

[0068] It can be understood that in this embodiment, by setting the fragrance housing 100 as the split first housing 180 and second housing 190, it is not only convenient to fabricate the internal structure of the fragrance housing 100, but also convenient to arrange relevant components in the fragrance housing 100 to prepare the required system.

[0069] The implementation principle of a multi - flavor fragrance system provided by an embodiment of this application is as follows:

[0070] In use, the control main board 700 controls the operation of the fan 300. The fan 300 rotates to send air flow from the air inlet 130 into the first chamber 110 and the second chamber 120 in sequence. Inside the second chamber 120, the air flow enters the aroma chamber 170 from the aroma excitation inlet 413 and the chamber inlet 171 in sequence. When the air flow enters the aroma chamber 170, it passes through the aroma generating device 200 and excites its aroma. After excitation, the air flow containing aroma is discharged from the chamber outlet 172 of the aroma chamber 170 and further discharged to the release port 140 from the aroma excitation outlet 414. Subsequently, the air flow containing aroma discharged from the release port 140 is guided via the guiding structure 500 and circulates into the vehicle through the ventilation duct of the vehicle. When it is necessary to switch the aroma, the control main board 700 controls the operation of the rotary drive motor 420. The output end of the rotary drive motor 420 rotates to drive the gear 440 to rotate. The gear 440 drives the toothed ring 430 engaged therewith to rotate, so as to make the switching roller 410 rotate. When the switching roller 410 rotates, a group of aroma excitation inlets 413 and aroma excitation outlets 414 provided on the inner side and the outer side of the roller can be respectively communicated with the chamber inlet 171 and the chamber outlet 172 of any aroma chamber 170, so as to enable the air flow to excite the aromas of the aroma generating devices 200 at different positions.

[0071] In this application, a rotatable switching roller 410 is provided; at the same time, by reasonably setting the position and structure of the switching roller 410, specifically, a plurality of aroma generating devices 200 are arranged between the inner layer 411 and the outer layer 412 of the switching roller 410, and at the same time, a group of aroma excitation inlets 413 and aroma excitation outlets 414 for exciting the aromas of the aroma generating devices 200 are provided on the inner layer 411 and the outer layer 412 of the roller; when it is necessary to switch the aroma, the switching roller 410 can be driven to rotate, so that the group of aroma excitation inlets 413 and aroma excitation outlets 414 are distributed on both sides of the aroma generating devices 200 at different positions, so as to achieve the purpose of exciting the aromas of the aroma generating devices 200 at different positions by air flow. In this application, the positions of a plurality of aroma generating devices 200 always remain fixed. When it is necessary to add or replace the aroma, there is no need to re-identify and recognize the circumferential positions of the plurality of aroma generating devices 200, so the operation is more convenient.

[0072] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0073] The above-described embodiments merely represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all fall within the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
