Description

Technical Field

[0001] This invention relates to the field of VR experience and multi-sensory interaction technology, and in particular to a VR experience device and method for digital art galleries. Background Technology

[0002] Virtual reality (VR) technology, with its immersive visual and auditory experience, has been widely used in digital art galleries to recreate art scenes and create atmosphere. Especially in the presentation of nature-themed art, natural elements such as rain scenes and the smell of earth are key factors in enhancing the viewer's sense of immersion and emotional resonance. However, current VR experience devices on the market still have significant shortcomings in simulating the tactile and olfactory experiences of natural environments, making it difficult to achieve true "full-sensory immersion." Specifically: 1. The simulation of rain is not realistic enough. In existing technologies, attempts to simulate the effect of rain often employ spraying or micro-droplet application. While this method provides a degree of moisture, it easily wets users' clothing and devices, causing discomfort and safety hazards. Furthermore, it cannot accurately simulate the granular feel, falling speed, and temperature changes of raindrops. For instance, the sensation of warm summer rain differs significantly from that of cold autumn rain, and current devices often lack the ability to regulate raindrop temperature, resulting in a monotonous and distorted tactile experience.

[0003] 2. The singularity and static nature of odor simulation In terms of olfactory simulation, existing devices mostly use fixed scent boxes or disposable fragrance release devices, resulting in a limited range of scent types and an inability to dynamically switch scents based on the scene. For example, the scent of damp earth after a summer rain is distinctly different from the cool earth scent after an autumn rain, and current technologies lack the ability to differentiate and adapt to seasonal and scene-specific scents, making it difficult to achieve synchronized interaction between scent and visual content.

[0004] 3. Lack of coordination and system integration in multi-sensory experiences In existing VR experience devices, sensory modules such as vision, hearing, touch, and smell often operate independently, lacking a unified control logic and coordination mechanism. For example, the release of the tactile sensation of rain and the smell of soil is often disconnected from the VR visual content, causing users to see a rain scene visually but not simultaneously experience the corresponding tactile and olfactory stimuli, seriously affecting the immersion and the overall integrity of artistic expression.

[0005] 4. Post-experience handling and cleaning issues Traditional rain simulations often leave water stains inside the experience chamber, and lingering odors are difficult to remove quickly, affecting the experience for subsequent users and the efficiency of equipment maintenance. Existing equipment generally lacks efficient and automated cleaning and recycling mechanisms, increasing the operational burden on venues.

[0006] In summary, existing VR experience devices have significant shortcomings in multi-sensory reproduction of natural scenes, particularly in the realism of rain tactile sensations, dynamic odor adaptation, and multi-sensory coordination, which urgently require breakthroughs. Therefore, it is necessary to develop a VR experience device capable of simulating rain without getting wet, switching seasonal odors, intelligent multi-sensory linkage, and possessing self-cleaning capabilities, to meet the demands of digital art museums for high-quality, highly realistic immersive experiences. Summary of the Invention

[0007] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a VR experience device and method for digital art museums, so as to solve the technical problems of existing VR experience devices that easily wet users when simulating the feeling of rain, poor tactile realism, single odor simulation that cannot be linked with seasons or scenes, and lack of coordination and real immersion in multi-sensory experience.

[0008] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A VR experience device for a digital art museum includes an experience chamber for users to experience the experience. The experience chamber is equipped with a display and an operating table installed on the display. The operating table is provided with a placement slot for placing VR glasses. The experience chamber is provided with a sealed door and a rain shower mechanism to reproduce the realistic experience of natural rain.

An air collection channel connected to the mixing chamber via a second air pipe is fixed along the periphery of the display. A guide shroud is fixed on the air collection channel. A storage tank connected to the first air pipe via a discharge pipe is mounted on the mixing chamber. The storage tank is used to store microparticles simulating raindrops. A discharge valve is provided on the discharge pipe. A temperature control component for adjusting the temperature of the microparticles is provided inside the mixing chamber. A recycling component for collecting the microparticles is provided inside the experience chamber. The temperature of the microparticles entering the mixing chamber is adjusted in real time by the temperature control component. At the same time, the first fan transports the microparticles to the air collection channel through the second air pipe via the first air pipe, and sprays them to the user through the guide shroud.

[0009] As a preferred technical solution of this application, the temperature control component includes a semiconductor refrigeration chip installed in the mixing chamber, the cooling surface of the semiconductor refrigeration chip being located inside the mixing chamber, the heat dissipation surface of the semiconductor refrigeration chip being located outside the mixing chamber, a heating plate being installed inside the mixing chamber, and a protective frame being installed along the periphery of the semiconductor refrigeration chip and the heating plate, the protective frame being provided with a first partition net.

[0010] As a preferred technical solution of this application, it also includes an odor switching mechanism, which includes a feeding channel symmetrically fixed in the top box. Supports are installed in the top box, each opposite to one of the feeding channels. A passive block is fixed to the side of the support near the feeding channel. A slider is slidably connected to the bottom of the support. A reset component for the slider to move and compress is provided at the bottom of the movable seat. A movable seat near the feeding port of the feeding channel is fixed to the bottom of the slider. A release groove for accommodating the passive block and the material block is provided in the movable seat. A rotating rod is rotatably connected in the top box. A rotating plate is fixed to the end of the rotating rod near the movable seat. The rotating plate is arc-shaped at both the end away from the rotating rod and the end near the two movable seats. A motor connected to the rotating rod is fixed to the experience chamber. An air jet component for dispersing the material is provided in the top box.

[0011] As a preferred technical solution of this application, the jet assembly includes a venturi tube communicating with the second air pipe and a nozzle communicating with the venturi tube and corresponding to the upper part of the release groove. A hanging plate is installed in the top box, and sensing blocks are symmetrically installed on the hanging plate. A disc cooperating with the sensing blocks is provided on the rotating plate, and a solenoid valve connected to the sensing blocks is provided on the venturi tube.

[0012] As a preferred technical solution of this application, a collection box that is slidably installed inside the top box and fits against the bottom of the movable seat is provided in the release groove, and a sliding hole corresponding to the collection box is provided in the release groove.

[0013] As a preferred technical solution of this application, the reset component includes a bottom groove provided at the bottom of the movable seat for the slider to slide, and a spring connected to the slider is fixed in the bottom groove.

[0014] As a preferred technical solution of this application, the slider is fixedly provided with a slide bar on one side corresponding to the length direction of the bottom groove, and a groove for the slide bar to slide is provided on the opposite side wall along the length direction of the bottom groove.

[0015] As a preferred technical solution of this application, the recycling component includes a recycling box assembled along the length of the outer side of the experience chamber and a collection cover connected to the recycling box and located inside the experience chamber. A second fan is fixedly installed on the side of the recycling box opposite to the collection cover.

[0016] As a preferred technical solution of this application, a collection box is installed at the bottom of the recycling bin, and a pull-out box close to the collection cover is provided inside the collection box. A second partition net is provided inside the recycling bin, and the second partition net and the side of the pull-out box close to the second fan are on the same vertical line.

[0017] A VR experience method for digital art museums, using the aforementioned VR experience device for digital art museums, includes the following steps: S1: According to the instructions of the VR content on the display, the first fan of the rain shower mechanism is started to deliver airflow into the mixing box. At the same time, the display controls the discharge valve of the storage tank to open, so that the micro particles in the storage tank enter the mixing box through the discharge pipe. S2: The temperature control component adjusts the temperature of the microparticles entering the mixing chamber according to the VR scene instructions, so that the microparticles reach the preset raindrop temperature. After the temperature is adjusted, the microparticles enter the air collection channel through the second air tube with the airflow, and are delivered to the user's body surface by the guide hood, simulating the tactile experience of natural rain with a sense of temperature. S3: The recycling component uses negative pressure suction to collect micro-particles scattered inside the experience chamber in real time.

[0018] The VR experience device and method for digital art galleries described in this invention have the following beneficial effects: 1. This solution uses micro-particles to simulate raindrops through a rain shower mechanism, and with the help of a temperature control component, it can adjust the temperature of the particles in real time. This can simulate the feeling of rain in different seasons and scenarios, avoiding the discomfort of getting wet caused by traditional water mist spraying, and improving the realism and comfort of rain shower simulation. 2. This solution uses an odor switching mechanism to automatically switch between the earthy scents of autumn and summer based on the VR content. Combined with the jet spray component, it achieves rapid and uniform diffusion of the odor, realizing a multi-sensory fusion of touch and smell, and enhancing the user's immersion in the natural-themed art scene. 3. This solution achieves automatic collection and recycling of micro particles after use through recycling components, which facilitates reuse, reduces equipment operation and maintenance costs, and ensures the cleanliness of the experience chamber.

Detailed Implementation

[0030] The present invention will be further described in detail below with reference to the accompanying drawings. This detailed description is an illustration in conjunction with exemplary embodiments of the invention, including various details of the embodiments to aid understanding, and should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the invention. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0031] Specifically, refer to Figures 1-13 As shown, a VR experience device for a digital art museum includes an experience chamber 1 for users to experience the device. The experience chamber 1 is equipped with a monitor 4 and an operating console 401 mounted on the monitor 4. The operating console 401 has a placement slot for VR glasses. The experience chamber 1 is equipped with a sealed door 7 and a rain shower mechanism to recreate the realistic experience of natural rain. The rain shower mechanism includes a first fan 2 installed on the top of the experience chamber 1 and a mixing box 202 connected to the first fan 2 via a first air pipe 201. An air collection channel 3 connected to the mixing box 202 via a second air pipe 203 is fixed along the periphery of the display 4. A guide hood 301 is fixed on the air collection channel 3. A storage tank 204 connected to the first air pipe 201 via a discharge pipe 205 is mounted on the mixing box 202. A discharge valve 206 is provided on the discharge pipe 205. A temperature control component for adjusting the temperature of micro particles is provided inside the mixing box 202. A recycling component for collecting micro particles is provided inside the experience chamber 1. The temperature of the microparticles entering the mixing chamber 202 is adjusted in real time by the temperature control component. At the same time, the first fan 2 transports the microparticles to the air collection channel 3 through the second air pipe 203 via the first air pipe 201, and sprays them to the user by the guide shroud 301.

[0032] The following is a supplementary explanation based on the above structure: At least two sides of the experience chamber 1 are made of transparent material, for example, the two sides along the length of the experience chamber 1 are made of tempered glass, and a sealing strip is provided along the contact area between the tempered glass and the experience chamber 1. This ensures the sound insulation effect of the experience chamber 1 while allowing passing visitors to view the interior of the experience chamber 1. The first fan 2 delivers airflow to the mixing chamber 202 through the first air pipe 201. Simultaneously, when connected to the display 4 in the rain scene within the VR glasses, the display 4 opens the discharge valve 206, allowing the microparticles used to simulate raindrops in the storage tank 204 to be mixed into the first air pipe 201 and enter the mixing chamber 202 through the discharge pipe. The temperature control component then uses real-time adjustment of the temperature of the airflow and microparticles (the mixing chamber 202 is equipped with a signal connection to the display 4). A temperature sensor (not shown in the figure; the temperature sensor is a conventional technology in this field and will not be described in detail here) is used to bring the microparticles to the temperature of raindrops, further enhancing the user experience. The temperature-controlled microparticles enter the air collection channel 3 through the second air pipe 203 with the airflow and are guided to the user by the guide hood 301, making the user experience of rain more realistic. Here, the air collection channel 3 is a gantry type, and there are three guide hoods 301, which are horizontally set on the side of the top of the gantry closest to the user and vertically set on the two sides of the gantry closest to the user, so as to realize the simulated raindrops coming from different directions. The microparticles that fall into the experience chamber 1 after contacting the user can be recycled by the recycling component to achieve the effect of resource recycling.

[0033] Furthermore, in this embodiment, the temperature control component includes a semiconductor cooling chip 207 installed inside the mixing chamber 202. The cooling surface of the semiconductor cooling chip 207 is located inside the mixing chamber 202, and the heat dissipation surface of the semiconductor cooling chip 207 is located outside the mixing chamber 202. A heating plate is installed inside the mixing chamber 202, and a protective frame is installed around the semiconductor cooling chip 207 and the heating plate 208. A first partition net is provided on the protective frame.

[0034] The following is a supplementary explanation based on the above structure: the semiconductor cooling chip 207 of the temperature control component can cool the mixing chamber 202, and the heating plate can heat the mixing chamber 202. Both of them work in conjunction with the temperature sensor to achieve precise temperature control. The temperature control component can also use an air compressor or heating wire to achieve temperature regulation, and there are no restrictions here.

[0035] Furthermore, this embodiment also includes an odor switching mechanism, which includes symmetrically fixed feeding channels 501 within the top box 5. Supports 502, each opposite to one of the feeding channels 501, are installed within the top box 5. A passive block 506 is fixed to the side of each support 502 near the feeding channel 501. A slider 503 is slidably connected to the bottom of the support 502. A reset assembly for moving and compressing the slider 503 is provided at the bottom of the movable seat 504. The bottom of the slider 503 is fixed with an opening corresponding to the feeding channel 501. The adjacent movable seat 504 has a release slot 505 for accommodating the passive block 506 and the material block. The top box 5 is rotatably connected to a rotating rod 507. A rotating plate 508 is fixed on one end of the rotating rod 507 near the movable seat 504. The rotating plate 508 is arc-shaped at both the end away from the rotating rod 507 and the end close to the two movable seats 504. The experience chamber 1 is fixed with a motor 509 connected to the rotating rod 507. The top box 5 is equipped with an air jet assembly for dispersing the material.

[0036] The following are supplementary explanations based on the above structure, such as... Figures 5-7 As shown, the two feeding channels 501 contain expansion bags with autumn and summer earthy scents, respectively. Initially, each release slot 505 contains one scent expansion bag. When the user experiences a rain scene in VR, the display 4 sends a signal to the motor 509 to switch between the autumn and summer earthy scents matching the rain scene. The motor 509 drives the rotating plate 508 to rotate either side of the two feeding channels 501 via the rotating rod 507. Since the ends of the rotating plate 508 and the moving seat 504 are both arc-shaped, when the rotating plate 508 rotates and approaches the moving seat 504, the arc-shaped design allows the rotating plate 508 to smoothly press the moving seat 504 to move. The moving seat 504 drives the slider 503 to move on the support 502, while simultaneously being located in the release slot. The odor-filled expansion bag (also known as the material block) contains not only soil gas but also micro-gravity rubber clay. The gravity rubber clay not only provides gravity to the expansion bag but also causes the bursting expansion bag to stick together in sheets when it is squeezed later. It will be squeezed with the passive block 506 until it breaks, releasing the soil odor. The soil odor will enter the air collection channel 3 through the top box 5 with the airflow and be sprayed out by the guide hood 301. Combined with micro-particles to simulate raindrops, users can smell the soil odor while feeling the raindrops, making the experience more realistic and achieving an immersive effect. When the expansion bag releases the soil odor, the airflow of the second air pipe 203 can be diverted and accelerated by the jet component and sprayed towards the expansion bag, so that the soil odor can be accelerated to diffuse into the top box 5, thereby making the soil gas flowing out of the top box 5 more uniform.

[0037] like Figures 4-6As shown, the jet assembly includes a venturi tube 6 connected to the second air pipe 203 and a nozzle 602 connected to the venturi tube 6 and corresponding to the upper part of the release slot 505. A hanging plate 604 is installed in the top box 5. Sensor blocks 605 are symmetrically installed on the hanging plate 604. A disc 603 that cooperates with the sensor block 605 is provided on the rotating plate 508. A solenoid valve 601 that is signal-connected to the sensor block 605 is provided on the venturi tube 6.

[0038] The following is a supplementary explanation based on the above structure: When the rotating plate 508 rotates to either side of the autumn soil scent expansion bag or the summer soil scent expansion bag, it simultaneously drives the disc 603 to perform a circular motion. When the disc 603 passes the sensing block 605 corresponding to either side of the autumn soil scent expansion bag or the summer soil scent expansion bag, the sensing block 605 is sensed and sends a signal to the display 4. The display 4 receives the signal and simultaneously sends a command to the solenoid valve 601, causing the solenoid valve 601 to open automatically. Simultaneously, based on the pipeline distribution design (e.g., Figure 5 As shown), the gas in the second air tube 203 will be diverted into the Venturi tube 6. When the airflow enters the Venturi tube 6, the Venturi effect can be used to accelerate the airflow and spray it through the nozzle 602 towards the released earthy smell, so that the earthy smell can be quickly and evenly diffused into the entire top box 5, thereby achieving a more uniform earthy smell flowing out of the top box 5. It is worth noting that the sensing block 605 can be a metal detector, and the disk 603 is made of metal. When the disk 603 passes by the metal detector, it is detected and sends a signal to the display 4. At the same time, the sensing block 605 and the disk 603 can be implemented by other sensing methods, such as magnetic detection and the cooperation between magnets.

[0039] like Figure 7 and Figure 9 As shown, a first collection box 607 that is slidably installed inside the top box 5 and fits against the bottom of the movable seat 504 is provided in the release groove 505. A sliding hole corresponding to the first collection box 607 is provided in the release groove 505. Here, after the expansion bag breaks and releases the soil smell, the passive block 506 and the release groove 505 squeeze and cooperate to compress the broken expansion bag into a sheet shape. The sliding hole at the bottom of the release groove 505 can guide the broken and compressed expansion bag into the first collection box 607 for collection.

[0040] like Figure 7 and Figure 8As shown, the reset assembly includes a bottom groove 5020 at the bottom of the movable base 504 for sliding the slider 503. A spring 5021 connected to the slider 503 is fixed inside the bottom groove 5020. A slider 5022 is fixed on one side of the slider 503 corresponding to the length direction of the bottom groove 5020. A groove 5023 for sliding the slider 5022 is provided on the opposite side wall along the length direction of the bottom groove 5020. When the slider 503 moves, it compresses the spring 5021. When the rotating plate 508 moves away from the movable base 504, the spring 5021 releases its elastic force and resets the slider 503 and movable base 504, so as to prepare for the next operation. Simultaneously, when the movable seat 504 resets, the release groove 505 will correspond to the feeding channel 501, and the expansion bag will fall into the release groove 505 under the action of gravity. During the movement of the slider 503, the sliding cooperation between the slider 5022 and the groove 5023 is used to limit the slider 503 and also provide support for the slider 503. Considering the weight of the movable seat 504 and the slider 503, the relative support surfaces of the slider 5022 and the groove 5023 can be smoothly polished, or a lubricant can be used to achieve a lubrication effect, so as to ensure that the weight of the movable seat 504 and the slider 503 will not affect the movement.

[0041] like Figure 1 and Figure 2 As shown, the recycling assembly includes a recycling box 8 mounted along the outer length of the experience chamber 1 and a collection cover 801 connected to the recycling box 8 and located inside the experience chamber 1. A second fan 802 is fixed on the side of the recycling box 8 opposite to the collection cover 801. A second collection box 803 is installed at the bottom of the recycling box 8. A pull-out box 804 close to the collection cover 801 is provided inside the second collection box 803. A second partition net is provided inside the recycling box 8. The second partition net and the side of the pull-out box 804 close to the second fan 802 are on the same vertical line.

[0042] like Figure 1 and Figure 10 As shown, when the second fan 802 starts, it creates negative pressure inside the recycling box 8, which draws the micro-particles of simulated raindrops scattered in the experience chamber 1 into the recycling box 8 through the collection cover 801. At the same time, the second partition net 805 can block the micro-particles, keeping them at the top of the drawer box 804. When the second fan 802 stops working, they will fall freely into the drawer box 804 for collection. The staff can pull the drawer box 804 out from the second collection box 803 and process the collected micro-particles.

[0043] A VR experience method for digital art galleries, using a VR experience device for digital art galleries as described above, includes the following steps: S1: According to the instructions in the display 4VR, the first fan 2 of the rain shower mechanism is started to deliver airflow into the mixing box 202. At the same time, the display 4 controls the discharge valve 206 of the storage tank 204 to open, so that the micro particles in the storage tank 204 enter the mixing box 202 through the discharge pipe 205. Specifically, when the VR system enters a rainfall scene, the display 4 controls the discharge valve 206 and the first fan 2 to open. The microparticles in the storage tank 204 enter the mixing box 202 through the discharge pipe 205. When the microparticles come into contact with the airflow of the first fan 2, the airflow provides a certain force for the microparticles to enter the mixing box 202.

[0044] S2: The temperature control component adjusts the temperature of the microparticles entering the mixing box 202 according to the VR scene instructions, so that the microparticles reach the preset raindrop temperature. After the temperature is adjusted, the microparticles enter the air collection channel 3 through the second air pipe 203 with the airflow, and are delivered to the user's body surface by the guide hood 301 to simulate the tactile experience of natural rain with temperature. Specifically, based on VR content instructions (such as "summer showers" or "autumn cold rain"), the display 4 sends a start signal to the temperature control component and the first fan 2. The first fan 2 starts, generating a stable airflow, which is transported to the mixing chamber 202 through the first air pipe 201 to provide power for subsequent particle conveying. The temperature control component starts simultaneously. The temperature sensor inside the mixing chamber 202 monitors the temperature inside the chamber in real time. Depending on the scenario, if simulating "summer rain," the heating plate operates to heat the air and microparticles inside the mixing chamber 202 and flowing through it. If simulating "autumn rain" or "cold rain," the cooling surface of the semiconductor cooling chip 207 activates to cool the air and microparticles inside the mixing chamber 202. The target temperature is preset by the VR content program, and the temperature control component adjusts through feedback to ensure that the airflow inside the mixing chamber 202 quickly reaches and stabilizes within the target temperature range (e.g., 28-32℃ for summer rain, 12-16℃ for autumn rain), providing a preheated or precooled environment for the microparticles to enter, rapidly reaching the preset raindrop temperature within the mixing chamber 202. Subsequently, the temperature-controlled airflow of particles passes through the air collection channel 3 and is sprayed towards the user at different angles by the top and side guide hoods 301, simulating the realistic tactile sensation of rain accompanied by a temperature sensation.

[0045] S3: The recycling component uses negative pressure suction to collect micro-particles scattered inside the experience chamber in real time.

[0046] Specifically, the second fan 802 of the recycling component starts, using negative pressure to draw the spilled microparticles into the recycling bin 8 through the collection hood 801. After being intercepted by the mesh screen, they fall into the collection box 804 for recycling. Simultaneously, the odor switching mechanism automatically resets under the action of the reset component spring 5021 and loads in new odor material blocks. Broken residue falls into the bottom second collection box 803. All equipment is then shut down in sequence, ready for the next use.

[0047] The implementation principle of a VR experience device and method for a digital art museum according to an embodiment of this application is as follows: After the user enters the experience chamber 1 and wears VR glasses, the display system 4 issues an instruction based on the VR content (such as "summer showers" or "autumn cold rain"), starts the relevant modules to prepare the simulated environment, the first fan 2 starts, generates airflow and delivers it to the mixing box 202 through the first air pipe 201.

[0048] Temperature regulation: The temperature control component works according to the needs of the scene - the heating plate is activated for summer rain, and the semiconductor cooling chip 207 is activated for autumn rain, so that the airflow in the mixing box 202 reaches the preset temperature (e.g., 28-32℃ for summer rain and 12-16℃ for autumn rain).

[0049] Particle release and mixing: Display 4 controls the opening of discharge valve 206, and micro particles in storage tank 204 fall into mixing box 202, where they quickly mix with temperature-controlled airflow to form simulated raindrops with temperature sensitivity.

[0050] Multi-angle spraying: The mixed temperature-controlled particulate airflow enters the air collection channel 3 through the second air pipe 203, and is evenly sprayed onto the user's body surface through the top (horizontal) and side (vertical) guide hoods 301, simulating the tactile and temperature sensation of real rain.

[0051] Odor simulation and switching: Based on the VR scene, the display 4 controls the motor 509 to drive the rotating plate 508 to rotate, and selects the soil odor expansion bag corresponding to the season (summer or autumn).

[0052] Odor release: The rotating plate 508 squeezes the corresponding movable seat 504, causing the expansion bag to rupture and releasing the odor.

[0053] Odor diffusion: The jet assembly is activated, blowing high-speed airflow toward the rupture, causing the odor to spread quickly and evenly within the top chamber 5, and then blown toward the user through the main airflow via the air collection channel 3, achieving a fusion of olfactory and tactile experiences.

[0054] Recycling and Reset Cleaning: Particle Recycling: The second fan 802 is started, and the scattered micro particles are sucked into the recycling box 8 through the collection cover 801 by negative pressure. After being filtered by the second screen 805, they fall into the drawer box 804 for recycling.

[0055] Mechanism reset: The odor switching mechanism automatically resets under the action of spring 5021, the moving seat 504 returns to the initial position, and the feeding channel 501 is replenished with new odor expansion bags; the residue of the ruptured expansion bag falls into the bottom first collection box 607.

[0056] Device shutdown: Each module shuts down in sequence, the system returns to standby mode, and it is ready for the next experience.

[0057] All structures in this application can be customized in terms of material and length according to actual usage. The attached drawings are schematic structural diagrams, and the actual dimensions can be adjusted accordingly.
