Description

Technical Field

[0001] This invention relates to the field of taste training technology, and in particular to a learning and memory training aid device for multiple odor substances. Background Technology

[0002] Scent learning training is a method to enhance memory and cognitive abilities through the sense of smell. It can be used for various purposes, such as improving olfactory sensitivity, aiding memory, and reducing anxiety. Several different scents are selected for training. Common scents include coffee, vanilla, lemon, and rose. You can choose your favorite or easily accessible scents. Each time you smell a particular scent, try to associate it with a specific memory or situation.

[0003] Existing devices for odor learning and memory typically involve placing different odor objects at the nose and training memory through the released odors. However, this is cumbersome and inconvenient, making it difficult to switch between multiple odor substances, which reduces the effectiveness of the device. Furthermore, different odor substances can easily cross-contaminate during use, affecting taste judgment. Additionally, the lack of odor concentration can also impair odor identification. Therefore, these problems need to be addressed. Summary of the Invention

[0004] Based on the technical problems existing in the background technology, the present invention proposes a learning and memory training auxiliary device for multiple odor substances.

[0005] This invention proposes a learning and memory training aid device using multiple odor substances, comprising a base and a rotating platform. A vertical cylinder is vertically fixedly connected to the center of the top of the base. A connection hole is formed on the outer surface of the vertical cylinder. A fan is installed at the top of the inner part of the vertical cylinder, and the fan is located at the top of the connection hole. An air supply mechanism is provided inside the base. The rotating platform is rotatably connected to the top of the base. A circular hole is vertically penetrating through the surface of the rotating platform, and the circular hole is located on the outer surface of the vertical cylinder. Multiple connecting seats are fixedly connected to the top of the rotating platform, and the multiple connecting seats are interconnected. All of the multiple connecting seats are located on the outer surface of the vertical cylinder. The rotating platform surface is curved. Multiple levers are fixedly connected to the surface. Each of the multiple connecting seats has a vertically penetrating circular groove at its top, which extends through the surface of the rotating platform. Each of the multiple circular grooves has a connection port on its inner wall, which mates with the connection hole. By rotating the rotating platform and the multiple connecting seats, each connection port can be connected to the inside of the vertical cylinder, facilitating the dissipation of odors from the bottles placed inside the circular grooves. This allows for switching between different odors, improving the effectiveness of the device. It also facilitates the replacement of the bottles inside each circular groove, thus enhancing the ease of use of the device.

[0006] Preferably, the gas supply mechanism includes an air pump, which is installed at the bottom of the base. The output end of the air pump is fixedly connected to a connecting pipe, and one end of the connecting pipe is fixedly connected to a vertical pipe. The vertical pipe passes through the surface of the base, and the top end of the vertical pipe is located at the top of the base, so that external gas can be delivered to the connecting pipe and the vertical pipe through the air pump.

[0007] Furthermore, a second arc-shaped groove is formed at the bottom of the rotating platform, and the top end of the vertical tube is disposed inside the second arc-shaped groove. Bottles are placed inside multiple circular grooves, and first springs are installed at the bottom of each of the multiple circular grooves. Multiple bottles are respectively disposed at the top ends of multiple first springs. Vertical grooves are formed through the tops of multiple connecting seats, extending through the surface of the rotating platform. U-shaped tubes are fixedly connected to the surfaces of multiple bottles, with one end of each U-shaped tube disposed on the outer surface of the bottle and the other end disposed at the bottom inside the bottle. The multiple U-shaped tubes are slidably connected... The base is connected to the top of each vertical slot. A trigger switch is installed on the top of the base and is located in one of the corresponding circular slots. The bottom of the outer ring is provided with a first arc-shaped groove and is located inside the first arc-shaped groove. The trigger switch is connected to the bottom of the multiple placement bottles and is electrically connected to the air pump. This allows the multiple placement bottles to be placed in each circular slot and restricts the vertical sliding of each placement bottle within the multiple circular slots. When the placement bottle slides downwards, it will contact the trigger switch, which can control the operation of the air pump.

[0008] Preferably, the top of the rotating platform is provided with an outer ring, which is sleeved on the outer surface of multiple connecting seats. Multiple support columns are fixedly connected to the arc surface of the outer ring, and one end of each of the multiple support columns is fixedly connected to the top of the base. A top plate is installed on the top of the outer ring, and an arc-shaped cover is fixedly connected to the center of the top of the top plate. The arc-shaped cover is located at the top of the vertical cylinder, and multiple ventilation holes are opened on the surface of the arc-shaped cover to protect the surface of the multiple connecting seats, while allowing the emitted odors to leak out through the ventilation holes on the surface of the arc-shaped cover.

[0009] Furthermore, a first magnet is fixedly connected to the outer arc surface of each of the multiple connecting seats, and a multiple second magnet is fixedly connected to the inner wall of the outer ring. The multiple second magnets correspond to and cooperate with the first magnets respectively, which facilitates the rotation of the rotary table. At the same time, with the cooperation of the multiple first magnets and the multiple second magnets, the rotation position of the rotary table is positioned.

[0010] Preferably, a vertical rod is vertically slidably fitted onto the surface of the top plate. A button is fixedly connected to the top of the vertical rod, and a pressure plate is fixedly connected to the bottom of the button. The pressure plate corresponds to the interior of multiple circular grooves. A second spring is fitted onto the outer surface of the vertical rod. The bottom of the second spring is located at the top of the top plate, and the top of the second spring is located at the bottom of the button. An arc-shaped piece is fixedly connected to the bottom of the pressure plate. The arc-shaped piece cooperates with the tops of multiple bottles. A vent is opened on the surface of the arc-shaped piece, and the vent cooperates with multiple connection ports to restrict the vertical sliding of the pressure plate and the arc-shaped piece. This allows the corresponding outer ring to slide vertically simultaneously, so that the bottom of the support column can be inserted into the vertical tube, allowing gas to pass through the interior of the outer ring.

[0011] Furthermore, a top rod is vertically slidably fitted onto the surface of the base. The top end of the top rod is located inside the second arc-shaped groove. The top rod corresponds to the bottom of multiple bottles. A connecting block is fixedly connected to the bottom end of the top rod. Fixed shafts are fixedly connected to both sides of the surface of the connecting block. A fixed block is fixedly connected to one side of the interior of the base. A rotating rod is rotatably connected to one side of the base surface. One end of the rotating rod is located inside the base. Rotating shafts are fixedly connected to both sides of the surface of the rotating rod. The rotating rod is rotatably connected to the inside of the fixed block. Both rotating shafts are rotatably fitted onto the fixed block. Inside the block, a pressing plate is fixedly connected to the higher end of the rotating rod. The connecting block is slidably connected to the inside of the rotating rod. A groove is opened on the surface of the rotating rod. Both fixed shafts are slidably connected to the inside of the groove. A pick-and-place opening is opened on the top of the top plate. The pick-and-place opening corresponds to multiple placement bottles. A cover plate is installed on the top of the top plate. The cover plate is rotatably connected to the top of the top plate. The cover plate is set on the outer surface of the pick-and-place opening. When the pressing plate is pressed, the top rod can slide upward, so that the placement bottle placed in the corresponding circular groove can be pushed out, making it easier to pick up the placement bottle.

[0012] In this invention, multiple bottles can be placed inside the circular groove during use, allowing multiple scents to be used simultaneously and sequentially, thereby achieving a scent training effect and improving the effectiveness of the device.

[0013] During use, the bottle placement machine placed inside each circular slot is ventilated, and the corresponding circular slot is sealed by a pressure plate to prevent the odors from mixing between multiple bottles. At the same time, the coordinated setting of the air pump and fan allows the odors in the corresponding bottles to be better released, thereby improving the practicality of odor training.

[0014] By manually pressing down on the button, the rotating rod will rotate upwards at the end away from the button. With the connection of the fixed shaft and the connecting block, the top rod will slide upwards, thus pushing the corresponding bottle upwards. At the same time, the cover will open, allowing the upward-sliding bottle to be taken out for easy replacement. Attached Figure Description

[0024] Reference Figure 7 and Figure 8 In a preferred embodiment, a top rod 82 is vertically slidably mounted on the surface of the base 1. The top end of the top rod 82 is located inside the second arc-shaped groove 28. The top rod 82 corresponds to the bottom of a plurality of placement bottles 7.

The rotating rod 8 is rotatably connected to the interior of the fixing block 15. Both rotating shafts 83 are rotatably mounted on the bottom of the base 1. Inside the fixed block 15, a pressing plate 81 is fixedly connected to the higher end of the rotating rod 8. A connecting block 85 is slidably connected inside the rotating rod 8.

When the pressing plate 81 is pressed, the top rod 82 can slide upward, so that the placement bottle 7 placed in the corresponding circular groove 23 can be pushed out, making it easier to pick up the placement bottle 7.

[0025] In this invention, when in use, the cover plate 43 on the top of the top plate 4 can be opened to allow the placement bottle 7 containing the object to be inserted through the inlet on the surface of the top plate 4, and the placement bottle 7 will be placed inside the corresponding circular groove 23. At the same time, the U-shaped tube 71 on the surface of the placement bottle 7 will be placed inside the U-shaped tube 71. Then, the rotating platform 2 can be rotated by manually sliding the lever 21. Through the cooperation of multiple first magnets 26 and multiple second magnets 32, during the rotation of the rotating platform 2, one of the circular grooves 23 will be aligned with the bottom of the pressure plate 52. Then, by manually pressing the button 5, the pressure plate 52 and the arc-shaped piece 54 will slide downward through the vertical rod 51, and the second spring 53 will be compressed.

[0026] At this time, the arc-shaped plate 54 will press the corresponding placement bottle 7 downwards, and the placement bottle 7 will also compress the first spring 210 inside the circular groove 23.

At the same time, during the downward sliding of the placement bottle 7, the placement bottle 7 will also come into contact with the trigger switch 14, and the trigger switch 14 will be turned on. The trigger switch 14 controls the drive air pump 6, which delivers external air through the connecting pipe 61 and the vertical pipe 62. Simultaneously, with the connection of the U-shaped pipe 71, the air enters the bottom of the placement bottle 7 through the U-shaped pipe 71, allowing the odor inside the placement bottle 7 to flow upwards. Then, it flows through the air leak 55, the connecting port 25, and the connecting hole 12 into the vertical cylinder 11. The triggering of the trigger switch 14 also controls the drive fan 13, which blows the odor flowing into the vertical cylinder 11, causing the odor to leak out through the arc-shaped cover 41 and the vent 42 on the surface of the top plate 4.

[0027] When the button 5 is stopped, the pressure plate 52 and the arc-shaped piece 54 will slide upward under the action of the second spring 53, and the bottle 7 will also slide upward under the action of the first spring 210. At this time, the trigger switch 14 will no longer be triggered, and the air pump 6 and the fan 13 will also stop. Then the rotating table 2 can be rotated, which can release the odor from the bottle 7 inside the other circular groove 23. Different odors can be released, thereby achieving the training effect.

[0028] When it is necessary to remove the bottle 7 inside the circular groove 23, the button plate 81 can be pressed down manually. Under the connection of the rotating rod 8, the end of the rotating rod 8 away from the button plate 81 will rotate upward. Under the connection of the fixed shaft 86 and the connecting block 85, the push rod 82 will slide upward, thereby pushing the corresponding bottle 7 upward. At the same time, the cover plate 43 will be opened, and the upward-sliding bottle 7 can be taken out, which is convenient for replacing the bottle 7, thereby improving the ease of use of the device. The device is equipped with a battery to power the air pump 6 and the fan 13 when in use.
