Description

Technical Field

[0001] This invention relates to the field of olfactory interaction, specifically to an interactive display system for preventing cross-contamination of various plant spices. Background Technology

[0002] Museums, science centers, and similar venues often feature plant spice exhibition areas. These areas typically utilize display systems to simultaneously showcase various types of spices in different forms, including seeds, leaves, flowers, roots, and stems. However, existing spice display technologies suffer from the following problems: 1) Olfactory interaction and odor prevention are mutually exclusive: To enable visitors to interact with the fragrance, the sealed structure or airflow channel needs to be opened. However, the aromas of different fragrances will permeate each other, confusing visitors' olfactory perception, causing the air in the exhibition area to become turbid, affecting the environment of other exhibition areas, and reducing the visitor experience. If a completely sealed structure is used to prevent odors from mixing, the interactive experience of fragrance release cannot be achieved, losing the fun of popular science display. Visitors cannot intuitively feel the characteristics of the fragrances, which affects the popular science effect.

[0003] 2) Exhibits are easily damaged and contaminated: Open display or allowing visitors to take the spices and smell them can damage precious spices, such as destroying their fragile structure or getting them contaminated with oil, affecting the integrity and value of the exhibits.

[0004] 3) Uncontrollable aroma release: The aromas in existing interactive display systems are mostly released naturally or by simple valves, and the preset duration cannot be adapted to the characteristics of different fragrances. Strong fragrances are prone to releasing too much and being pungent, while light fragrances are prone to releasing too little and being unnoticeable, which affects the audience experience.

[0005] Insufficient aroma with no indication: Staff cannot promptly detect the depletion of fragrances, allowing exhibits to remain on display for an extended period after they have lost their aroma, thus affecting the overall quality of the exhibition.

[0006] It is evident that existing display systems fail to resolve the core contradiction of "interaction leading to cross-contamination of aromas," and cannot achieve personalized adaptation to preset durations, nor can they effectively prevent damage and contamination of exhibits. Therefore, there is an urgent need for a multi-category plant fragrance interactive display system that takes into account anti-cross-contamination of aromas, precise interactive fragrance release, adjustable duration, exhibit protection, and automatic prompts. Summary of the Invention

[0007] The purpose of this invention is to provide a multi-category plant fragrance anti-odor interactive display system, which solves the core contradiction of existing display cases where interactivity and odor prevention are mutually exclusive, as well as derivative problems such as uncontrollable aroma release, lack of indication for insufficient aroma, unbalanced air pressure in storage compartments, and fragile exhibits.

[0008] The present invention achieves the above objectives through the following technical solutions: A multi-category plant fragrance anti-odor interactive display system includes a sealing module, which consists of multiple sealing units for classifying and storing plant fragrances. The sealing module is connected to an air replenishment chamber. Each sealing unit is equipped with an air replenishment valve and a fragrance release valve. The sealing unit contains a fragrance generation module, which is connected to an interactive control system. The interactive control system is used to receive trigger signals, control the fragrance generation module to generate a fragrance with plant fragrance, and deliver the fragrance to the fragrance release valve. The fragrance release valve is used to release the fragrance unidirectionally to the outside of the sealing module. The sealing unit gas replenishment valve is used to unidirectionally replenish the gas in the gas replenishment chamber into the sealing unit where the sealing unit gas replenishment valve is located, so as to maintain the gas pressure balance in the sealing unit and prevent the fragrance of different types of plant fragrances from mixing into the sealing unit.

[0009] As a further optimization of the invention, the fragrance generation module includes an air storage bladder and an air bladder compression component fixed inside the sealing unit and connected to the fragrance release valve. The air storage bladder stores the fragrance volatilized from the plant fragrances inside the sealing unit. The air storage bladder is provided with an air bladder replenishment valve. The air storage bladder obtains fragrance replenishment from the internal space of the sealing unit through the air bladder replenishment valve. The air bladder compression component is used to squeeze the air storage bladder so that the air storage bladder delivers fragrance to the fragrance release valve.

[0010] As a further optimization of the invention, when the air pressure inside the air reservoir rises to the positive pressure threshold, the fragrance release valve opens; when the air pressure inside the air reservoir falls below the positive pressure threshold, the fragrance release valve closes.

[0011] As a further optimization of the invention, when the air pressure inside the air reservoir is positive, the air reservoir valve is closed, and when the air pressure inside the air reservoir is negative, the air reservoir valve is opened.

[0012] As a further optimization of the invention, when the air pressure inside the sealing unit drops to the slight negative pressure threshold, the air supply valve of the sealing unit opens, and when the air pressure inside the sealing unit returns to a state of basic equilibrium with the ambient atmospheric pressure, the air supply valve of the sealing unit closes.

[0013] As a further optimization of the invention, the sealing unit is equipped with a touch button. When the touch button is pressed and the interactive control system detects the trigger signal, the airbag compression component squeezes the air storage bag and starts timing. The preset duration of the timing can be customized by the operator according to the aroma concentration of the plant fragrance and stored in the interactive control system. After the preset duration is reached, the airbag compression component resets and the air storage bag rebounds.

[0014] As a further optimization of the invention, the sealing unit is provided with an indicator light for prompting the replacement of plant fragrance. The number of times threshold is preset in the interactive control system according to the storage amount and volatilization efficiency of the plant fragrance and can be adjusted as needed. When the number of fragrance releases reaches the number of times threshold, the indicator light is lit and turns off after the plant fragrance is replaced and the count is reset.

[0015] As a further optimization of the invention, the top of the air reservoir is provided with an air inlet connector, the air reservoir replenishment valve is installed on the air inlet connector at the top of the air reservoir, and the bottom of the air reservoir is provided with an exhaust port, which is connected to the aroma release valve through a three-way pipe.

[0016] As a further optimization of the invention, the sealing unit is provided with a panel, and a sealing ring and a buckle are provided between the panel and the sealing unit. The sealing ring is a silicone sealing gasket, and the buckle is a quick-release buckle. The sealing ring and the buckle achieve an airtight connection between the panel and the sealing unit.

[0017] As a further optimization of the invention, the sealing unit is provided with an aroma release port, the aroma release valve is installed at the aroma release port, the air replenishment chamber is provided with a main air inlet, the main air inlet is provided with an odor filter layer, and the main air inlet is used to replenish air into the air replenishment chamber to maintain a slightly positive pressure state inside the air replenishment chamber.

[0018] The beneficial effects of this invention are as follows: 1) This invention receives a trigger signal through an interactive control system, controls the fragrance generation module to generate a fragrance with plant-based aromas, and releases the fragrance to the outside of the sealed module through a fragrance release valve, simulating the natural fragrance release process of the fragrance. The gas in the gas supply chamber is unidirectionally supplied into the sealed unit through the gas supply valve of the sealed unit, which maintains the gas pressure balance in the sealed unit, prevents the fragrances of different types of plant-based fragrances from mixing into the sealed unit, improves the volatilization efficiency, and allows the audience to selectively release the fragrance of the fragrance in a single sealed unit. The system combines interactive fragrance smelling with anti-odor mixing functions. 2) This invention achieves complete isolation between the sealing units during the interactive aroma release process by using independent sealing units in conjunction with three sets of one-way valves and an elastic sealing gas storage bag. The leakage rate of the modular sealing unit is <0.005cm. 3 / (m 2 •d•atm) significantly reduces the cross-contamination rate and enhances the audience experience. It releases fragrance quantitatively through the combination of air storage bag, fragrance release valve, air bag replenishment valve and magnetic push rod. The fragrance release process is stable and quiet, avoiding the airflow impacting the fragrance during the release. 3) This invention uses three sets of one-way valves working together, and a magnetic push rod to stably squeeze the air storage bag, ensuring stable fragrance release pressure. The fragrance release time can be customized and preset according to the characteristics of the fragrance, which can be adapted to fragrances with different fragrance concentrations, avoiding the fragrance being too strong and pungent or too weak and unpleasant. 4) This invention has an intelligent prompt function. When the number of fragrance releases reaches the preset threshold, the counting module will automatically issue a prompt that the fragrance is insufficient through the indicator light, reminding the operator to replace the plant fragrance in time, so as to avoid the failure of the exhibit display and reduce the operation and maintenance costs.

[0019] 5) This invention optimizes details such as the selection of air-storage bag materials, the limitation of push rod stroke, and the anti-interference design of circuits to ensure that the display system can operate stably and reliably for a long time in museums, science museums and other scenarios, thereby reducing the failure rate.

Detailed Implementation

[0021] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0022] Example like Figure 1-4As shown, this embodiment relates to a multi-category plant fragrance anti-odor interactive display system, suitable for museums, science museums, and other similar settings. The display system includes a sealing module, which consists of multiple modular sealing units 1. Different types of plant fragrances are stored separately within these units 1, and each unit 1 is independently sealed to completely prevent odor penetration between different units. A centralized purification air supply chamber 2 is located at the rear of the sealing module. An air inlet is located on the rear wall of each sealing unit 1, and an air supply valve 3 is installed at the air inlet. Two fragrance release ports H1 are located on the front wall of each sealing unit 1, and fragrance release valves 4 are installed at each fragrance release port H1. When releasing fragrance, the fragrance from a single sealing unit 1 can be released unidirectionally to the outside of the sealing module through the fragrance release valves 4, and the gas from the air supply chamber 2 can be unidirectionally replenished into the sealing unit 1 where the air supply valve 3 is located through the air supply valves 3. Audiences can selectively interact with individual sealed units 1 to smell the fragrance, preventing different fragrances from mixing with each other outside the sealed module and also preventing the fragrances from different types of plant spices from mixing into the individual sealed unit 1. In this embodiment, the sealing unit air supply valve 3, the fragrance release valve 4, and the airbag air supply valve 52 are all one-way valves, and there are a total of three sets of the above-mentioned one-way valves on the sealing module.

[0023] Each sealed unit 1 is fixedly equipped with a dual-interface air reservoir 51 and an air reservoir compression component 53. The air reservoir 51 has an air inlet at the top and an air outlet at the bottom. An air reservoir replenishment valve 52 is installed on the air inlet, and the air outlet is connected to two fragrance release valves 4 through a three-way pipe. The air reservoir 51 stores the aroma emitted by the plant fragrances in the sealed unit 1, and it is replenished with aroma from the internal space of the sealed unit 1 through the air reservoir replenishment valve 52. The air reservoir compression component 53 is preferably a miniature electromagnetic push rod, and the push rod end of the electromagnetic push rod is equipped with an arc-shaped pressure plate 54. This electromagnetic push rod can also be replaced by a cylinder, hydraulic cylinder, or other components. The air reservoir 51, air reservoir replenishment valve 52, air reservoir compression component 53, and pressure plate 54 constitute the fragrance generation module 5, and the sealed unit 1 is equipped with a touch button 6. This display system also has an interactive control system connected to the fragrance generation module 5 and the touch button 6. In this embodiment, the interactive control system is a touch-linked circuit system.

[0024] During the interactive display of plant fragrances, when the audience presses the touch button 6, the interactive control system detects the valid trigger signal and triggers the electromagnetic push rod. The electromagnetic push rod squeezes the air storage bag 51 through the pressure plate 54. After the air storage bag 51 is under pressure, its volume shrinks and the air pressure increases. When the air pressure rises to a positive pressure threshold higher than the standard atmospheric pressure, for example, 50Pa to 100Pa, the fragrance release valve 4 opens. At this time, the air bag replenishment valve 52 closes, and the fragrance stored in the air storage bag 51 is released from the fragrance release port H1 through the fragrance release valve 4 to the outside of the sealed module, allowing the audience to experience the fragrance interaction. After the preset time is reached, the electromagnetic push rod resets. At this time, the air storage bag 51 rebounds under its own elastic force, forming a negative pressure inside. The fragrance release valve 4 closes, and the air bag replenishment valve 52 opens, allowing the air storage bag 51 to draw in the fragrance from the sealing unit 1. At the same time, a momentary negative pressure is generated inside the sealing unit 1. When the air pressure drops to a slightly negative pressure threshold of 50Pa to 100Pa below the standard atmospheric pressure, the sealing unit replenishment valve 3 opens, and the gas in the replenishment chamber 2 is replenished into the sealing unit 1 through the sealing unit replenishment valve 3 until the air pressure inside the sealing unit 1 is restored to a state of basic equilibrium with the ambient atmospheric pressure. Then, the sealing unit replenishment valve 3 closes.

[0025] Specifically, please refer to Figure 2 and Figure 3 The sealing unit 1 is a uniformly sized square sealing structure. Sealing unit 1 uses a high-barrier membrane for sealing, providing excellent airtight sealing performance. A detachable operation panel 7 is located on the front of sealing unit 1, and panel 7 is made of a transparent, scratch-resistant material. A mounting groove is formed on the front side wall of sealing unit 1, and panel 7 is installed in this groove. A sealing ring 8 is provided between panel 7 and the mounting groove, and a snap-fit ​​9 is provided between panel 7 and the front side wall of sealing unit 1. The sealing ring 8 is preferably a silicone sealing gasket, and the snap-fit ​​9 is preferably a quick-release snap-fit. The airtight connection of panel 7 is achieved through the silicone sealing gasket and the quick-release snap-fit.

[0026] The front wall of the sealing unit 1 is equipped with a touch button 6 and two fragrance release ports H1, located below the panel 7, with the touch button 6 and fragrance release ports H1 arranged adjacent to each other. The sealing unit air supply valve 3 is the only communication channel between the sealing unit 1 and the air supply chamber 2, allowing only clean air from the air supply chamber 2 to flow into the sealing unit 1 in one direction, thus preventing the fragrance of the plant fragrance in the sealing unit 1 from flowing back into the air supply chamber 2. After removing the panel 7, plant fragrance exhibits can be directly placed and removed without disturbing core components such as the internal air storage bladder 51 and electromagnetic push rod. After the fragrance is replaced, the panel 7 is inserted into the sealing ring 8 and secured with the buckle 9 to restore the airtight state of the sealing unit 1, significantly improving the efficiency of museum exhibit rotation.

[0027] Each sealing unit 1 incorporates a built-in elastic, sealed air reservoir 51. The air reservoir 51 is made of medical-grade or food-grade polymer materials resistant to fragrance corrosion, such as, but not limited to, FKM fluororubber or highly corrosion-resistant VMQ silicone rubber. These materials possess excellent chemical resistance and aging resistance, ensuring good elasticity and airtightness even after prolonged contact with fragrance components. When the air inlet and exhaust ports are closed, the air reservoir 51 is a completely sealed independent cavity, exhibiting good shape memory and elastic recovery capabilities. To prevent plastic deformation of the air reservoir due to excessive compression, the stroke and thrust of its associated micro-electromagnetic actuator are precisely calculated and configured by a touch-sensitive linkage circuit system. The sealing unit 1 surpasses laboratory testing standards, achieving a leakage rate of <0.005cm. 3 / (m 2 •d•atm), to eliminate the risk of cross-contamination of different plant spices inside the display system, where atm is standard atmospheric pressure.

[0028] The touch-sensitive linkage circuit system includes a central control motherboard, a driver, a position sensor, a pressure sensor, and a power module. The position sensor detects the stroke of the electromagnetic push rod, while the pressure sensor, located between the output shaft of the electromagnetic push rod and the pressure plate 54, detects the squeezing force of the electromagnetic push rod. The central control motherboard detects the degree of extension of the electromagnetic push rod through the pressure sensor and controls its extension action through the driver. The central control motherboard also detects whether the extension of the electromagnetic push rod has reached the preset stroke through the position sensor. Extension stops when the electromagnetic push rod reaches the preset stroke. This touch-sensitive linkage circuit system ensures that the deformation of the air reservoir 51 caused by each compression does not exceed 80% of its elastic limit, thus guaranteeing the long-term service life and performance stability of the air reservoir 51. The air reservoir 51 has two independent one-way valve interfaces, realizing precise control functions of "one-way aroma release + one-way air replenishment," and is a core component for resolving the contradiction between "interaction and preventing cross-contamination of odors." The fragrance generation module 5, composed of an air reservoir 51, a magnetic push rod, and other structures, can release fragrance outward from the fragrance release port H1 in a unidirectional, quantitative, and quiet manner, preventing cross-contamination of flavors and avoiding the impact of airflow generated during the fragrance release process on plant fragrances.

[0029] Furthermore, one end of the air reservoir 51 is equipped with a rigid-sealed air outlet connector, which is sealed to the air inlet of the fragrance release valve 4, forming the only gas output channel of the air reservoir 51; the other end of the air reservoir 51 is equipped with an air inlet connector, which is sealed to the air outlet of the air reservoir replenishment valve 52, and the air inlet of the air reservoir replenishment valve 52 is connected to the internal space of the sealed unit 1 outside the air reservoir 51. The aroma of the plant fragrance naturally volatilized in the sealed unit 1 will accumulate in the space of the sealed unit 1, providing a stable gas source for replenishing the air reservoir 51.

[0030] In this embodiment, the three sets of one-way valves each perform their respective functions and work together to form a complete gas control closed loop of "airbag fragrance release - airbag replenishment - sealing grid pressure balance," achieving rapid response and high reliability. The fragrance release valve 4, airbag replenishment valve 52, and sealing unit replenishment valve 3 preferably employ a thin-plate valve structure with a preload spring. By adjusting the spring's preload, the opening pressure threshold of each valve can be precisely set, and the flow rates of the three valves can be optimally matched, ensuring smooth and controllable gas flow.

[0031] Specifically, the aroma release valve 4 is a positive one-way valve, installed on the inner side of the front wall of the sealing unit 1. One end of it is connected to the air reservoir 51, and the other end is connected to the aroma release port H1. When the compression pressure of the air reservoir 51 reaches a threshold, its internal air pressure rises. The aroma release valve 4 only opens when the compression pressure of the air reservoir 51 reaches the threshold (exemplarily 50Pa to 100Pa higher than the standard atmospheric pressure), releasing the aroma to ensure comfortable perception by the human body. When the internal air pressure of the air reservoir 51 is lower than the positive pressure threshold or when the air reservoir 51 rebounds, the aroma release valve 4 automatically closes to prevent backflow of outside air and cross-flow of aroma between different sealing units 1.

[0032] The airbag replenishment valve 52 is a reverse one-way valve, installed on the air inlet connector of the air reservoir 51. The air inlet of the airbag replenishment valve 52 is connected to the internal space of the sealing unit 1. The airbag replenishment valve 52 only opens when the air reservoir 51 rebounds and generates negative pressure. After the airbag replenishment valve 52 opens, it draws in the fragrance accumulated in the sealing unit 1, completing the air supply replenishment of the air reservoir 51. When the air reservoir 51 is squeezed, the air pressure inside the air reservoir 51 is negative. At this time, the valve plate of the airbag replenishment valve 52 is closed by pressure, ensuring the airtightness and pressure stability of the air reservoir 51.

[0033] The sealing unit air replenishment valve 3 is a pressure balancing one-way valve, installed on the rear side wall of the sealing unit 1. One end of the sealing unit air replenishment valve 3 is connected to the air replenishment chamber 2, and the other end is connected to the internal space of the sealing unit 1. The sealing unit air replenishment valve 3 only opens when the air pressure inside the sealing unit 1 drops to a slightly negative pressure threshold (exemplarily 50Pa to 100Pa below standard atmospheric pressure) during the air replenishment process of the air reservoir 51. After the sealing unit air replenishment valve 3 opens, the clean air drawn in from the air replenishment chamber 2 balances the air pressure of the sealing unit 1, ensuring continuous and efficient volatilization of the fragrance. After the air pressure inside the sealing unit 1 returns to a state of basic equilibrium with the ambient atmospheric pressure, the sealing unit air replenishment valve 3 automatically closes to prevent fragrance leakage.

[0034] In other embodiments, these one-way valves can be replaced with two-way valves. Simultaneously with the operation of the airbag compression component 53, the opening and closing of the two-way valves can be controlled via a touch-sensitive linkage circuit system to achieve one-way ventilation. Furthermore, in other embodiments, a non-touch-sensitive control system can be used to control the various electronic components of the display system; for example, a remote control system can be used to control the airbag compression component 53.

[0035] The miniature electromagnetic actuator is the core component that drives the elastic, sealed air reservoir 51 to contract and release fragrance. Each air reservoir 51 is equipped with one electromagnetic actuator. The electromagnetic actuator is fixed to the inner wall of the sealing unit 1, and its actuator end is connected to the outer wall of the air reservoir 51, without directly contacting the fragrance. The core operating logic of the electromagnetic actuator is as follows: When touch button 6 is pressed, the electromagnetic push rod receives a control signal from the central control board. The push rod extends and squeezes the air reservoir 51, raising the pressure inside the air reservoir 51 to the positive pressure threshold of the fragrance release valve 4. The fragrance release valve 4 opens, releasing the fragrance outwards, while the air reservoir replenishment valve 52 closes under pressure. The electromagnetic push rod maintains the squeezing state for a preset time. The preset time is set by the operator according to the fragrance concentration; for example, a preset time of 10 seconds is set for fragrances with a strong fragrance, and a preset time of 20 seconds is set for fragrances with a weak fragrance. After the preset time is reached, the central control board sends a reset signal, the push rod quickly retracts back to its original position, the air reservoir 51 rebounds and generates negative pressure, the fragrance release valve 4 closes, and the air reservoir replenishment valve 52 opens, drawing in the fragrance from the sealing unit 1. The air reservoir 51 completes its replenishment and regeneration. The replenishment of the air reservoir 51 causes the air pressure inside the sealing unit 1 to drop to a slight negative pressure threshold, triggering the opening of the sealing unit replenishment valve 3. Clean air from the replenishment chamber 2 flows into the sealing unit 1 to balance the air pressure.

[0036] The centralized purification air supply chamber 2 is an independent, sealed space located at the back of the sealing module. A main air inlet H2 is located on the outside of the air supply chamber 2, and an odor filter layer is installed inside the main air inlet H2. Outside air must pass through this odor filter layer to remove impurities and dust before entering the air supply chamber 2. To ensure reliable triggering of the sealing unit air supply valve 3, a micro-positive pressure maintenance module is installed inside the air supply chamber 2. This module is either a miniature silent fan or a combination of a micro-pressure differential sensor and an air inlet valve. When the micro-positive pressure maintenance module uses a linkage structure consisting of a micro-pressure differential sensor and an air inlet valve, the air inlet valve is located at the main air inlet H2 and connected to an external air source. The function of the micro-positive pressure maintenance module is to stably maintain the air pressure inside the air supply chamber 2 within a range 50 Pa to 200 Pa higher than the standard atmospheric pressure. The clean air inside the air supply chamber 2 provides pressure balance for all sealing units 1 through the sealing unit air supply valve 3, simplifying the structure and reducing maintenance costs.

[0037] The touch-sensitive linkage circuit system adopts a distributed touch design of "one touch button per unit," with each sealed unit 1 equipped with a touch button 6. Considering the electromagnetic complexity of the museum environment, the circuit system integrates an anti-interference module. This module includes a filter circuit at the signal input end and a metal shielding structure at the driver and central control board to prevent back electromotive force generated during electromagnetic actuator movement or external electromagnetic waves from interfering with the normal operation of the touch-sensitive linkage circuit system.

[0038] The central control motherboard is electrically connected to the touch buttons 6 and electromagnetic push rods of all sealed compartments, and pre-stores a database of the volatilization coefficients of different fragrances. The motherboard has a built-in counting module and a preset duration module. The counting module uses EEPROM or Flash memory, a non-volatile storage medium, to create an independent fragrance release statistics file for each sealed unit 1. The preset duration module allows operators to customize the extrusion holding time according to the characteristics of the fragrances, adapting to the needs of fragrances with different aroma concentrations. Each sealed unit 1 has an indicator light L for prompting the replacement of plant fragrances. When the fragrance release count of a sealed unit 1 reaches a preset threshold, the central control motherboard automatically controls the corresponding indicator light L to remain constantly lit, prompting staff to check or replace the fragrance. After replacement, the count can be reset with a simple operation.

[0039] The specific workflow is as follows: Standby state: The fragrance in the sealing unit 1 naturally evaporates and accumulates in the internal space of the sealing unit 1. The air bladder 51 is in the inflated state, and both the air bladder replenishment valve 52 and the sealing unit replenishment valve 3 remain closed; the air replenishment chamber 2 is maintained at a slightly positive pressure higher than the standard atmospheric pressure, for example, 50Pa to 200Pa, through the micro-positive pressure maintenance module. Previously, the operator had set the preset time according to the characteristics of the plant fragrance in each sealing unit 1 through the time preset module (e.g., the preset time for strong fragrances such as sandalwood and frankincense is set to 10 seconds, and the preset time for light fragrances such as agarwood and rose is set to 20 seconds); the counting module and the time preset module are in standby state.

[0040] Press-to-release fragrance process: The audience presses the touch button 6 of the sealing unit 1. The press signal is transmitted to the central control board. The central control board drives the push rod end of the corresponding electromagnetic push rod to extend and squeeze the air storage bag 51. The pressure in the air storage bag 51 rises to the positive pressure threshold (exemplarily 50Pa~100Pa higher than the standard atmospheric pressure). The fragrance release valve 4 opens and the fragrance is released through the fragrance release port H1. The air bag replenishment valve 52 is closed under pressure, and the electromagnetic push rod maintains the squeezing state for a preset time.

[0041] Reset and Air Replenishment Process: After the electromagnetic push rod extends for a preset duration, the central control board sends a reset signal, causing the electromagnetic push rod to quickly retract back to its original position. The air reservoir 51 rebounds and generates negative pressure, the fragrance release valve 4 closes, and the air reservoir replenishment valve 52 opens to draw in the fragrance from the sealing unit 1. The air reservoir 51 completes its refilling and regeneration. The air replenishment process of the air reservoir 51 causes a momentary negative pressure in the sealing unit 1. This momentary negative pressure is superimposed on the pressure change in the sealing unit 1 caused by the continuous evaporation of the fragrance. When the cumulative pressure in the sealing unit 1 drops to a preset micro-negative pressure threshold (exemplarily 50Pa to 100Pa below standard atmospheric pressure), the sealing unit replenishment valve 3 is triggered to open. The slightly positive pressure clean air from the replenishment chamber 2 flows into the sealing unit 1, restoring the pressure balance of the sealing unit 1. Subsequently, the sealing unit replenishment valve 3 closes, and the counting module automatically records one operation.

[0042] Triggering the process: When the number of fragrance releases reaches the threshold, indicator light L will stay on. Staff will open panel 7 and replace the fragrance, resetting the count. Indicator light L will then turn off.

[0043] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
