Description

Technical Field

[0001] The present invention relates to the technical field of olfactory training, and specifically to an interesting olfactory training instrument combined with a mobile phone app. Background Art

[0002] An olfactory training instrument is a device that helps improve olfactory sensitivity and recognition ability through various odor stimuli. It uses different odor samples and combines interesting interactive designs to encourage users to conduct olfactory memory and recognition training. This device is not only applicable to the rehabilitation treatment of patients with olfactory disorders, but also can be used as a daily training tool for improving olfactory sensitivity, helping users enhance their olfactory experience and improve their quality of life.

[0003] Although the existing olfactory training instruments can help improve olfactory sensitivity to a certain extent, there are still some disadvantages and deficiencies:

[0004] Single training mode: The designs of many olfactory training instruments are relatively single. Usually, they only conduct training through fixed odor samples, lacking diverse stimulation methods and interactivity, which may lead to a decrease in users' interest and participation;

[0005] Limited odor samples: The types of odor samples of existing devices are limited, usually only covering several common odors, making it difficult to meet the individual's perception needs for different odor types, resulting in a possibly incomplete training effect;

[0006] Lack of personalized training programs: Many olfactory training instruments are not customized according to the personalized needs of different users. Users have different olfactory levels, training progress, and goals, and need more flexible training programs to provide more effective training and rehabilitation;

[0007] Poor odor stability: The odor samples in some devices may have a decrease in odor stability and consistency due to storage conditions or long usage time, affecting the training effect;

[0008] Complicated or unfriendly operation: The operation interfaces of some olfactory training instruments may be relatively complicated. Especially for the elderly or patients with olfactory disorders, they are not intuitive or easy to operate, affecting their usage experience and training effect;

[0009] Lack of long-term tracking and feedback: Existing devices usually lack long-term tracking and feedback on the user's training process, making it difficult to evaluate the change in the user's olfactory level and unable to adjust the training intensity and content according to the user's actual progress.

[0010] Therefore, we propose an interesting olfactory training instrument combined with a mobile phone app. Summary of the Invention

[0011] To achieve the above object, the present invention provides the following technical solutions: A fun olfactory training device combined with a mobile phone app, including the following steps:

[0012] S1: Device hardware design

[0013] S1.1: Liquid storage tank: The device is equipped with multiple liquid storage tanks inside, and each tank stores a specific odor liquid (for example: ocean, grass, mint, floral and fruity scents, etc.). These liquids are made through specific formulas to ensure the stability and consistency of the odor. The storage tanks can be replaced or cleaned as needed to ensure the purity of the odor;

[0014] S1.2: Odor release device (atomization or air flow system): Use an ultrasonic atomizer or a micro air pump to convert the liquid in the storage tank into tiny aerosol particles, and accurately send the odor to the user's nose through the air flow. The odor is accurately blown towards the user wearing a mask or nasal mask through a small fan or air flow device;

[0015] S1.3: Mask / nasal mask design: The user wears a specially designed mask or nasal mask, which is equipped with a micro fan and an odor channel inside to ensure that the odor can be effectively and comfortably sent into the user's nasal cavity. The air flow inside the nasal mask can be adjusted to meet the needs of different users, ensuring that the odor is neither too strong nor too weak.

[0016] S2: Mobile phone APP design and control

[0017] S2.1: APP interface and functions: The mobile phone APP serves as the main control platform. Users can select different odor training options through the mobile phone. The APP interface includes: Odor selection: Users can select the odors they hope to experience from multiple odors (such as: ocean, grass, mint, floral and fruity scents, etc.). These odors will be displayed in the APP through icons and pictures to enhance the user's visual interaction experience; Odor concentration adjustment: Users can adjust the concentration of the odor according to their personal feelings to avoid the odor being too strong or too weak; Training mode: Different training modes can be set, such as single odor training, odor pairing training, odor memory training, etc.; Timing function: Users can set the duration and frequency of each training to help establish a regular olfactory training habit;

[0018] S2.2: Image and sound coordination: After each odor selection, the APP will display images related to the odor (such as ocean, flowers, forest, etc.) to enhance the immersion of the olfactory experience. To enhance the fun, the APP can also be accompanied by background music or natural sounds (such as the sound of waves, wind, etc.) to improve the user's training experience;

[0019] S2.3: Personalized Recommendation and Feedback: The APP will recommend suitable scent training combinations based on the user's historical training data and record the user's olfactory responses. During the training process, the APP will collect the user's feedback data in real time (such as perception intensity, scent recognition accuracy, etc.) and adjust the training difficulty according to the user's feedback.

[0020] S3: Training Process and Interaction

[0021] S3.1: Select Scent and Start Training: The user selects the training mode and scent type (such as "grass") through the APP. At this time, the APP will send a signal to the device to start atomizing the corresponding liquid, and the nasal mask will start delivering the scent for the user to conduct olfactory training.

[0022] S3.2: Combination of Vision and Smell: During the training process, the APP not only provides scent selection but also synchronously displays pictures related to the scent. For example, when selecting the "ocean" scent, the APP will show pictures of ocean waves and beaches and play natural sounds such as the sound of ocean waves to increase the fun of training. The user needs to judge and identify the scent type based on the scent prompt and make a selection on the APP for memory and recognition training.

[0023] S3.3: Progress Tracking and Feedback: The APP will record the user's olfactory responses and training progress, generate a feedback report in real time to help the user understand the changes in their olfactory level, provide long-term training data analysis, and adjust the training content and scent combination according to the training results to ensure that the user can gradually improve their olfactory sensitivity.

[0024] S4: Advanced Features and Personalization

[0025] S4.1: Diverse Scent Combinations: The APP allows the user to create personalized scent combination training. The user can select multiple scents for mixed training (such as "ocean + floral fragrance") to simulate a more complex scent environment and improve the olfactory recognition ability.

[0026] S4.2: Family Sharing and Multi-Person Training: Multiple family members can conduct different scent trainings through the same APP account, share training results and feedback with each other, and increase the interaction among family members.

[0027] S4.3: Regular Updates and Scent Expansion: The APP can provide scent update packages, and users can obtain new scent types regularly (such as "vanilla", "coffee", etc.) to maintain the freshness of training.

[0028] S5: Safety and Comfort

[0029] S5.1: All scent liquids in the device are made of non-toxic and harmless natural ingredients to ensure safety in use.

[0030] S5.2: The materials of the nose mask and the mouth mask are made of skin-friendly materials with good air permeability to ensure the comfort of users during long-term wearing.

[0031] S5.3: The device has a function of automatically adjusting the air flow inside to ensure that the smell is not too strong or uncomfortable for users.

[0032] Preferably, in the step S1, the material of the tank body is made of high-transparency plastic material (such as polycarbonate or high-density polyethylene) to ensure that the liquid components are clearly visible and durable. Each liquid storage tank needs to have a leak-proof function. Each tank stores a special odor liquid, which is made by a professional manufacturer according to the formula. In order to ensure the stability of the smell and long-term storage, the volatilization can be reduced through sealing technology (such as vacuum sealing). The liquid components include natural plant extracts and highly volatile spices to ensure that the smell is not harmful to the human body. The storage tank is designed to be detachable, so that users can easily replace or clean the tank. The device provides interfaces and liquid distribution channels that are easy to clean to ensure that the odor samples are not cross-contaminated. An ultrasonic atomizer (using the principle of ultrasonic oscillation) is used to convert the liquid into tiny particles. This method can ensure that the odor molecules are evenly and precisely distributed. The atomizer should be installed in the odor release area of the device, and the liquid is precisely regulated to avoid too high odor concentration. Through a small fan or air pump, the odor particles are quickly blown towards the mouth mask or nose mask. The air flow speed, direction and intensity should be adjustable to ensure that the smell is evenly sent into the user's nasal cavity without over-stimulating. The fan is selected to be of low noise and high efficiency to ensure the comfort of the user during training. The nose mask is made of highly breathable and skin-friendly silicone or flexible plastic material, which can ensure comfort during long-term wearing and will not cause allergic reactions to the skin. A adjustable air flow device (such as an internal micro-fan) is designed to adjust the size of the odor flow according to the user's needs. The flow rate of the smell can be remotely controlled through the APP to achieve a personalized training experience. Multiple odor channels are equipped inside the nose mask to evenly distribute the odor particles to both sides of the nasal cavity to ensure that the amount of smell inhaled each time is the same. Each nose mask is equipped with a filter to ensure that no impurities enter the nasal cavity.

[0033] Preferably, in step S2, an interface is created in the APP to list all supported odor options. Under each odor option, there is an attached relevant picture or short video introduction (for example: an image or video of ocean waves is attached beside the ocean odor). The user selects the target odor by clicking on the odor name, and then the device starts to work. The user can slide on the APP interface to adjust the odor concentration. By adjusting the fan speed and the working intensity of the atomizer, the output of the odor concentration is controlled. The concentration control bar in the APP shows the current concentration setting in real time. Different training modes are designed, such as: single odor recognition, odor pairing training (such as pairing two odors for the user to identify), and odor memory training (letting the user remember the previous odor and recall it). Each mode can be selected separately. The user can set the training duration (for example, 10 minutes, 20 minutes, etc.) and the weekly training frequency (such as daily, three times a week) in the APP. The APP will display a countdown and give a prompt when the training is completed. High-definition pictures or short videos related to the odor are displayed in the APP. For example, under the training option of "grass", a green grassland is displayed. The images are realized through professional design software and optimized to fit various mobile phone screen sizes. Each odor can be accompanied by corresponding natural background sounds (such as ocean waves sound for ocean odor, bird chirping sound for floral odor), and these sounds are played synchronously through the playback function of the APP. The sounds are played through the mobile phone speaker or the user's earphone. The APP records the odor selection, training duration, concentration setting, and the user's olfactory feedback for each training. After each training ends, the APP will provide suggestions according to the user's performance and generate a progress report, such as "85% of the odors were successfully identified today". According to the user's training progress and olfactory response, the APP will recommend suitable odor combinations or training difficulties. For example, for patients with olfactory disorders, a training mode with low concentration and single odor is recommended.

[0034] Preferably, in step S3, after the user opens the APP, selects the odor training mode, sets the training duration, and presses the "Start" button. The device starts releasing the corresponding odor according to the APP instruction. The user wears the nasal mask and starts the olfactory training. After the training starts, the atomizer sends the target odor into the user's nasal mask through the air flow system, and the user starts the training. After the user perceives the odor by smell, the user must select the odor type corresponding to the image displayed on the APP interface. If the user selects correctly, the APP will give a prompt and continue with the next task. If it is incorrect, a reminder will be given and the user will be required to try again. By combining images, videos, and sounds, the user's situational understanding of the odor is enhanced. For example, the "grassland" odor is paired with an image of grassland and the sound of a gentle breeze, enabling the user to better associate and remember the odor during the training process. After each training session, the APP will display the user's performance data, including the number of successfully identified odors, average reaction time, frequency of concentration adjustment, etc., and provide personalized suggestions. The user can view the historical training data, check the progress of each odor recognition, and set goals (e.g., successfully identify 10 odors within 30 days). The APP automatically adjusts the training difficulty based on long-term data feedback.

[0035] Preferably, in step S4, in the APP, the user is allowed to combine multiple odors for mixed training, such as "ocean + grass" or "floral + vanilla". The device can adjust the air flow intensity according to the selected odor combination to ensure that the user can smell the new mixed odor. Multiple users can be managed under one family account, and different training plans can be assigned to each family member. The user can view the training progress of themselves and other members, compare and motivate each other. New odor packs or odor training combinations are regularly released, and the user can download and install these new odor contents through the APP to ensure the freshness and challenge of the training content.

[0036] Preferably, in step S5, all the liquid odor components used are from natural plant extracts, meeting international safety standards, non-toxic and harmless, and the user can use them with confidence. The design of the nasal mask conforms to ergonomics, fits the facial contour, and uses a soft skin-friendly material to ensure comfort during long-term wear without causing a sense of compression or allergic reaction.

The interesting olfactory training device combined with a mobile phone app according to claim 1, characterized in that: In step S1, the tank body is made of a highly transparent plastic material (such as polycarbonate or high-density polyethylene) to ensure that the liquid components are clearly visible and durable. Each liquid storage tank must have a leak-proof function. Each tank stores a special odor liquid, which is made by a professional manufacturer according to a formula. In order to ensure the stability and long-term storage of the odor, the volatilization can be reduced by sealing technology (such as vacuum sealing). The liquid ingredients include natural plant extracts and highly volatile spices to ensure that the odor is not harmful to the human body. The storage tank is designed to be detachable, and the user can easily replace or clean the tank. The device provides an easy-to-clean interface and liquid distribution channel to ensure that the odor sample is not cross-contaminated, and an ultrasonic atomizer (using the principle of ultrasonic oscillation) is used to convert the liquid into tiny particles. This method can ensure that the odor molecules are evenly and accurately distributed. The atomizer should be installed in the odor release area of ​​the device, and the liquid is precisely regulated to avoid excessive odor concentration. The odor particles are quickly blown to the mask or nasal mask through a small fan or air pump. The air flow speed, direction and intensity should be adjustable to ensure that the odor is evenly delivered to the user's nasal cavity without excessive stimulation. The fan uses a low-noise, high-efficiency model to ensure the user's comfort during training. The nasal mask uses highly breathable, skin-friendly silicone or flexible plastic materials to ensure comfort when worn for a long time and will not cause allergic reactions to the skin. An adjustable air flow device (such as a built-in micro fan) is designed to adjust the odor flow according to user needs. The flow rate of the odor can be remotely controlled through the APP to achieve a personalized training experience. The nasal mask is equipped with multiple odor channels to evenly distribute the odor particles to both sides of the nasal cavity to ensure that the amount of odor inhaled each time is consistent. Each nasal mask is equipped with a filter to ensure that no impurities enter the nasal cavity.

3. The interesting olfactory training device combined with a mobile phone app according to claim 1, characterized in that: In step S2, an interface is created in the APP to list all supported odor options. Each odor option is accompanied by a related picture or short video introduction (for example, an image or video of waves next to the ocean odor). The user selects the target odor by clicking the odor name, and then the device starts working. The user can slide to adjust the odor concentration in the APP interface. The output of the odor concentration is controlled by adjusting the fan speed and the working intensity of the atomizer. The concentration control bar in the APP displays the current concentration setting in real time, and different training modes are designed, such as: single odor recognition, odor pairing training (such as pairing two odors for users to identify) and odor memory training (allowing users to remember previous odors and recall them). Each mode can be selected separately, and the user can set the training duration (for example, 10 minutes, 20 minutes, etc.) and the weekly training frequency (such as every day, three times a week) in the APP. The APP will display a countdown and give a prompt when the training is completed. High-definition pictures or short videos related to the odor are displayed in the APP. For example, a green meadow is displayed under the "grass" training option. The images are realized through professional design software and optimized to adapt to various mobile phone screen sizes. Each smell can be equipped with a corresponding natural background sound (such as ocean smell with the sound of waves, flower fragrance with birdsong), and these sounds are played synchronously through the APP's playback function. The sound is played through the mobile phone speaker or the user's headphones. The APP records the odor selection, training duration, concentration setting and user's olfactory feedback for each training. After each training, the APP will provide suggestions based on the user's performance and generate a progress report, such as "85% of the odors were successfully identified today". According to the user's training progress and olfactory response, the APP will recommend a suitable odor combination or training difficulty. For example, for patients with olfactory disorders, a low-concentration, single-odor training mode is recommended.

4. The interesting olfactory training device combined with a mobile phone app according to claim 1, characterized in that: In step S3, the user opens the APP, selects the odor training mode, sets the training duration, and then presses the "Start" button. The device starts to release the corresponding odor through the APP instruction. The user puts on the nasal mask and starts olfactory training. After the training starts, the atomizer sends the target odor into the user's nasal mask through the airflow system. The user starts training. After the user perceives the odor through the sense of smell, he must select the type of odor corresponding to the image displayed in the APP interface. If the user selects correctly, the APP will give a prompt and continue to the next task. If it is wrong, it will give a reminder and ask to try again. Through the combination of images, videos and sounds, the user's situational understanding of odors is improved, such as the "grassland" odor is accompanied by the image of the grassland and the sound of the breeze, so that the user can better associate and remember the odor during the training process. After each training, the APP will display the user's performance data, including the number of odors successfully identified, the average reaction time, the frequency of use of concentration adjustment, etc., and provide personalized suggestions. The user can view the historical training data, view the progress of each odor recognition, and set goals (for example: 10 odors can be successfully identified within 30 days). The APP automatically adjusts the training difficulty based on long-term data feedback.

5. The interesting olfactory training device combined with a mobile phone app according to claim 1, characterized in that: In step S4, in the APP, the user is allowed to combine multiple scents for mixed training, such as "ocean + grass" or "flowers + vanilla". The device can adjust the airflow intensity according to the selected odor combination to ensure that the user can smell the new mixed odor. Multiple users can be managed under one family account, and different training plans can be assigned to each family member. Users can view their own and other members' training progress, compare and motivate each other, and regularly release new odor packages or odor training combinations. Users download and install these new odor contents through the APP to ensure the freshness and challenge of the training content.
