[0024] The protective shell assembly 1 includes a placement shell 101, a movable cover 102, a leather handle 103 and a connecting through hole 105. The movable cover 102 is detachably connected to the placement shell 101. The leather handle 103 is symmetrically arranged on the upper surface of the movable cover 102. The leather handle 103 is fixedly connected to the movable cover 102. The movable cover 102 is provided with a odor emission hole 104. The middle position of the movable cover 102 is provided with a connecting through hole 105. A limiting slide groove 106 is provided at the bottom of the placement shell 101.

[0025] The docking teeth 202 are evenly distributed on the outer surface of the rotating ring 201, the connecting sliding plates 204 are evenly distributed on the upper surface of the rotating ring 201, the size of the sealing plate 211 is larger than the size of the top of the placement box 209, the shape of the bottom of the rotating limit rod 205 is a "cross" shape, and the position of the limit block 208 corresponds to the position of the card hole 206.

[0026] The fixed latch teeth 309 provided on the driving pulley 307 are meshedly connected with the fixed latch teeth 309 provided on the driven pulley 308 , the driving gear 313 is meshedly connected with the docking teeth 202 , and the position of the top end of the fixed push rod 316 corresponds to the position of the flip plate 214 .

[0027] The connecting through hole 105 penetrates the housing 101 . The position of the limiting sliding groove 106 corresponds to the position of the connecting track 314 . The sliding bracket 315 is slidably connected in the limiting sliding groove 106 .

[0028] The device can be connected to a VR device. When a situation related to a specific smell appears in the virtual scene, the VR device will send an odor trigger signal to the device. A signal receiver is set on the drive motor 302 to receive the signal sent by the VR device. The drive motor 302 is started according to the signal and drives the rotating ring to rotate, so that the designated placement box 209 is rotated to the bottom of the odor emission hole 104 and opened.

[0029] When using the device, different smells can be added to the device as needed before using it. The staff separates the movable cover 102 from the placement shell 101 and manually pulls the limit block 208 to make the limit block 208 squeeze the telescopic spring 207 and separate the limit block 208 from the rotation limit rod 205. At this time, the rotation limit rod 205 can rotate freely. The rotation limit rod 205 is placed in the rotation limit groove 203 until the connecting sliding plate 204 is placed on the upper surface of the rotating ring 201. Then, the rotation limit rod 205 is manually rotated to make the rotation limit rod 205 rotates 90°. At this time, the connecting sliding plate 204 cannot be separated from the rotating ring 201 under the action of the rotating limit rod 205. Then, the limit block 208 is released. The limit block 208 is reset to the initial state under the action of the telescopic spring 207 and is reconnected with the clamping hole 206 opened on the rotating limit rod 205. After the connection between the clamping hole 206 and the rotating limit rod 205 is completed, the rotating limit rod 205 cannot rotate independently. According to the above method, multiple placement boxes 209 are installed on the rotating limit groove 203 by connecting the sliding plate 204 and the rotating limit rod 205.

[0030] The sealing plate 211 is manually pulled to displace along the fixed track 210 and squeeze the reset spring 212 to open the placement box 209. Different odor dispersants are then placed in different placement boxes 209. The sealing plate 211 is then released. The sealing plate 211 is reset under the action of the reset spring 212 and closes the placement box 209 to prevent odors from mixing. The movable cover 102 is then reconnected to the placement shell 101 and fixed.

[0031] The device is put on the neck of the experiencer. At this time, the staff can manually control the sliding bracket 315 to slide along the connecting track 314 and the limiting slide groove 106, so that the sliding bracket 315 falls on the shoulder of the experiencer, so that the whole device is supported. The staff sends a signal to the driving motor 302 through the controller. The driving motor 302 starts after receiving the signal. The driving motor 302 starts to drive the driving pulley 303 to rotate. The driving pulley 303 rotates and drives the driven pulley 304 to rotate synchronously through the connecting belt 305. The driven pulley 304 drives the rotating shaft 306 to rotate. The rotating shaft 30 6 drives the active pulley 307 to rotate, the active pulley 307 drives the driven pulley 308 to rotate synchronously in the opposite direction through the fixed latch tooth 309, the driven pulley 308 and the active pulley 307 both drive the driven pulley 311 to rotate through the transmission belt 312, the driven pulley 311 drives the rotating shaft 310 to rotate, the rotating shaft 310 drives the driving gear 313 to rotate, the two driving gears 313 set on the support frame 301 rotate synchronously in the opposite direction, the driving gear 313 drives the rotating ring 201 to rotate through the docking tooth 202, so that different placement boxes 209 are moved to the bottom of the flavor emission hole 104.

[0032] When the storage box 209 moves to the bottom of the smell emission hole 104, the fixed push rod 316 contacts the flip plate 214 on the upper surface of the sealing plate 211. As the rotating ring 201 continues to rotate, the fixed push rod 316 pushes the sealing plate 211 to slide open through the flip plate 214. After the sealing plate 211 moves to the end position of the fixed track 210, the thrust exerted on the flip plate 214 is greater than the supporting force provided by the torsion spring 216. At this time, the flip plate 214 begins to rotate around the connecting shaft 215, so that the rotation of the rotating ring 201 will not be restricted by the fixed push rod 316. At the same time, it can be ensured that only the storage box 209 located below the smell emission hole 104 is in an open state, while the other storage boxes 209 on the rotating ring 201 are all in a closed state, thereby ensuring that only a single smell is smelled by the experiencer. The staff can achieve the purpose of switching different smells by controlling the opening and closing of the drive motor 302.

[0033] After using the device, the user can remove the device from the user through the leather handle 103, and can use the leather handle 103 to take the device to a designated location for storage. The above is the overall workflow of the present invention. The steps can be repeated the next time the device is used. The actual operation process is very simple and easy.

[0034] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.

[0036] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
