Description

Technical Field

[0001] This invention relates to the field of medical assistive device technology, and in particular to a sleep aid device for neurology. Background Technology

[0002] Patients in the neurology department commonly experience insomnia due to various factors such as neurological dysfunction, physical pain caused by the disease, psychological anxiety during treatment, and poor environmental adaptability. Insomnia is often characterized by difficulty falling asleep, shallow sleep, and frequent awakenings. Long-term insomnia not only exacerbates neurological damage but also weakens the body's immunity, severely impacting treatment effectiveness and prognosis. Currently, sleep aids for this group are relatively common, with the most widely used being white noise playback of rain sounds and aromatherapy spraying. The former regulates the patient's mood by playing preset synthetic rain sounds, while the latter uses plant extracts such as lavender and chamomile to stimulate the olfactory nerves, thereby aiding sleep.

[0003] However, clinical applications have revealed significant limitations in the adaptability of existing sleep aids, particularly the poor sleep-inducing effect of white noise with rain sounds on a large number of neurology patients. Because these patients often have neurosensory systems that are either sensitive or disordered, the white noise with rain sounds, mostly synthesized electronic sounds, lacks natural texture. Furthermore, the standardized arrangement of sound effects makes it difficult to match the individual relaxation needs of each patient. This results in most patients being insensitive to electronic sound stimulation, failing to effectively suppress nerve excitation or calm anxiety. More importantly, even when existing sleep aids attempt to incorporate rain-related sleep modes, they are often simple audio editing or electronic synthesis, failing to accurately simulate the unique frequency fluctuations, spatial layering, and differentiated sound effects of raindrops falling on different surfaces characteristic of real rain sounds, thus failing to present the true texture of natural rain sounds. In stark contrast, the sound of raindrops in the natural environment has a stable frequency rhythm, gentle sound pressure changes, and a realistic natural texture, which can accurately match the neurological perception characteristics of neurology patients. Research data shows that more than 60% of patients who are not sensitive to synthetic rain white noise can significantly shorten their sleep onset time and prolong their deep sleep time after listening to real raindrop sounds.

[0019] The sleep aid device for neurology provided by this invention has the following beneficial effects:

[0020] 1. Through the coordination of the timing and speed adjustment mechanism, the drive mechanism, and the water droplet launching mechanism, water droplets are launched from eight directions to impact vibrating plates of different materials. Since all the vibrating plates are constantly rotating, different white noises can be generated. This can simulate the white noise produced when raindrops fall on different materials due to changes in wind direction. The generated white noise is focused by a cone amplifier and delivered to the patient's ear, allowing the patient to listen to the realistic white noise simulating raindrops falling on different materials to fall asleep. This avoids the situation where some patients are not sensitive to the electronic sounds played by the player, resulting in poor sleep aid effects.

[0021] 2. After water droplets hit the vibrating plate, some stick to the side of the vibrating plate and drip down to the outer periphery of the round cover plate. They then drip through the through hole onto the top of the fragrance compression block. After absorbing water, the fragrance compression block releases a sleep-aiding aroma, which enters the interior of the sound chamber through the through hole. At the same time, another part of the water droplets will atomize due to the impact. At this time, the fan wheel rotates and draws in gas from the air inlet. After mixing with the sleep-aiding aroma, the gas is sprayed out from the mist outlet at the top, carrying the atomized water droplets. This not only has a humidifying effect, simulating the air humidity on a rainy day, but the volatile aroma also has a sleep-aiding effect.

[0022] 3. By starting the micro motor with the mechanical timer, the input end of the reducer is driven to rotate. At this time, the speed control lever drives the drive gears on both sides to rotate through the drive gear seven. This allows the rollers on both sides to rotate in opposite directions by adjusting the bushings. As a result, in the initial stage, the continuously variable speed wheel one drives the continuously variable speed wheel two on the left to rotate quickly. This also results in more water droplets being emitted and a greater impact force due to the centrifugal force in the initial stage of using the sleep aid device, simulating a heavy rain scene at the beginning of using the sleep aid device. In the later stage of sleep aid, the white noise gradually thins out and the volume gradually decreases, which is beneficial for patients to fall asleep better.

[0023] 4. The continuously variable speed wheel on the right rotates slowly at the beginning and gradually increases in the later stages of sleep aid. This causes all the vibrating plates of the impeller to rotate at a gradually increasing speed. This results in a high density of water droplets impacting the same vibrating plate in the initial stage. Furthermore, it can reduce the density of raindrops falling on the same material under varying rainfall conditions. In the initial stage, due to the high density and impact force of the water droplets, more atomized water droplets are generated, and more droplets fall onto the fragrance compression block. At this time, the impeller rotates slowly. Later, when there are fewer atomized water droplets, the number of droplets falling on the fragrance compression block also gradually decreases, and the impeller rotates faster. This ensures that the amount of atomized particles and sleep-aiding fragrance sprayed during the use of the sleep aid device remains constant. This maintains a constant level of air humidification and fragrance output, avoiding excessive or insufficient humidification that would render the air ineffective. It also prevents the fragrance concentration from fluctuating, which could stimulate the nerves or fail to achieve the desired sleep-aiding effect, thus improving the sleep aid device's overall effectiveness.

[0034] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0035] like Figures 1-8 As shown, this embodiment proposes a sleep aid device for neurology, characterized in that it includes:

[0036] The water filling section includes a water storage mechanism 6 for holding clean water;

[0037] The sound-emitting part includes an amplification mechanism 1, a drive mechanism 2, a water droplet emission mechanism 3, a windmill 7, a rotating seat 8, and a vibrating plate 9, which are used to emit sleep-aiding sounds;

[0038] The drive unit includes a fragrance storage mechanism 4 and a timing speed adjustment mechanism 5, which are used to drive the drive source of the drive mechanism 2 in the sound-generating part.

[0039] A drive mechanism 2 is fixedly installed in the middle of the amplification mechanism 1. A water droplet emission mechanism 3 is fixedly installed on the upper outer periphery of the drive mechanism 2. A rotating seat 8 is rotatably connected to the middle outer periphery of the drive mechanism 2. Vibrating plates 9 are evenly distributed on the upper outer periphery of the rotating seat 8. A wind wheel 7 is rotatably connected to the lower outer periphery of the drive mechanism 2. A water storage mechanism 6 is fixedly installed at the upper end of the amplification mechanism 1. A spice storage mechanism 4 is fixedly installed at the lower end of the amplification mechanism 1. A timer speed adjustment mechanism 5 is fixedly installed in the middle of the spice storage mechanism 4.

[0040] In this embodiment, the amplification mechanism 1 includes an amplification chamber 11. A water inlet 12 is fixedly connected to the upper middle part of the amplification chamber 11, and a water pipe 13 is fixedly connected to the lower end of the water inlet 12. A cone-shaped amplifier 14 is fixedly connected to the middle of the outer periphery of the amplification chamber 11. Mist exhaust holes 15 are evenly distributed on the upper part of the outer periphery of the amplification chamber 11, and air inlets 16 are evenly distributed on the lower part of the outer periphery of the amplification chamber 11.

[0041] In this embodiment, the water storage mechanism 6 includes a water storage tank 61. A vent cover 62 is threadedly connected to the middle of the upper end of the water storage tank 61. A water outlet sleeve 63 is fixedly connected to the middle of the lower end of the water storage tank 61. A sealing cover plate 64 is rotatably connected to the right side of the upper end of the water outlet sleeve 63 via a spring hinge. The inner circumference of the water outlet sleeve 63 is fitted onto the outer circumference of the water inlet 12.

[0042] Specifically, remove the water storage mechanism 6, open the vent cover 62, add clean water into the water storage tank 61, align the water outlet sleeve 63 with the connecting water inlet 12 at the upper end of the amplifier chamber 11, and put the water storage mechanism 6 back in. At this time, the sealing cover 64 is lifted by the connecting water inlet 12, so that clean water can enter the water inlet at the upper end of the drive chamber 21 through the connecting water inlet 12 and the connecting water pipe 13.

[0043] In this embodiment, the timing speed control mechanism 5 includes a speed control chamber 51, a micro motor 511, and two continuously variable speed (CVT) wheels 512. The upper drive end of the micro motor 511 is fixedly connected to a CVT wheel 510. The front end of the speed control chamber 51 is rotatably connected to a speed control lever 52. The front end of the speed control lever 52 is fixedly connected to a reducer 53. The front input end of the reducer 53 is fixedly connected to a mechanical timer 54. The front end of the rotating shaft of the mechanical timer 54 is fixedly connected to a knob 55. The rear end of the speed control lever 52 is fixedly connected to a drive gear 56. Both sides of the lower end of the drive gear 56 are meshed with drive gears 57. Each drive gear 57 is fixedly connected to an adjusting sleeve 58. Each adjusting sleeve 58 is rotatably connected to a roller 59. The lower end of each roller 59 is in contact with the upper ends of the continuously variable speed wheel 510. The upper end of each roller 59 is in contact with the lower end of the continuously variable speed wheel 512. Each continuously variable speed wheel 512 is fixedly connected to a drive shaft 513. Each end of the drive shaft 513 away from the continuously variable speed wheel 512 is fixedly connected to a bevel gear 514. Each bevel gear 514 is meshed with a bevel gear 515 at its upper end. Each bevel gear 515 is fixedly connected to a speed regulating sleeve shaft 516 at its middle.

[0044] In this embodiment, the lower ends of the speed regulating chamber 51, the reducer 53 and the mechanical timer 54 are all fixedly connected to the inner bottom wall of the spice chamber 41. The rear end of the knob 55 is rotatably connected to the front end of the spice chamber 41. The front and rear ends of the adjusting bushing 58 are rotatably connected to the middle ends of the front and rear sides of the speed regulating chamber 51. The end of the drive shaft 513 away from the continuously variable speed wheel 510 is rotatably connected to the middle of both sides of the speed regulating chamber 51. The lower outer periphery of the speed regulating sleeve shaft 516 is rotatably connected to the openings on both sides of the upper end of the speed regulating chamber 51.

[0045] Specifically, when the mechanical timer 54 starts the micro motor 511, it drives the input end of the reducer 53 to rotate. At this time, the speed regulating lever 52 drives the drive gears 57 on both sides to rotate through the drive gear 7 56. This, in turn, adjusts the rollers 59 on both sides to rotate in opposite directions through the adjusting bushing 58. This results in the continuously variable speed wheel 1 510 driving the continuously variable speed wheel 2 512 on the left to rotate quickly, while the continuously variable speed wheel 2 512 on the right rotates slowly. This causes the water droplets to be emitted in large quantities and the impact force to be large due to the centrifugal force in the initial stage of using the sleep aid device, simulating a heavy rain scene at the beginning of using the sleep aid device. In the later stage of sleep aid, the white noise gradually thins out and the volume gradually decreases, which is beneficial for the patient to fall asleep better. At the same time, the continuously variable speed wheel 2 512 on the right rotates slowly in the initial stage and gradually increases in speed in the later stage of sleep aid, causing the wind wheel to rotate slowly. 7. The rotation speed of all vibrating plates 9 gradually increases, achieving a high density of water droplets impacting the same vibrating plate 9 in the initial stage. This further enhances the density of raindrops falling on the same material under varying rainfall conditions. In the initial stage, due to the high density and impact force of the water droplets, more atomized water droplets are generated, resulting in more water droplets falling onto the fragrance compression block 45. At this time, the speed of the impeller 7 is slow. Later, when there are fewer atomized water droplets, the number of water droplets falling onto the fragrance compression block 45 gradually decreases, and the rotation speed of the impeller 7 gradually increases. This ensures that the amount of atomized particles and sleep-aiding fragrance sprayed remains constant during the use of the sleep aid device. This maintains a constant level of air humidification and fragrance output, preventing the air from becoming too humid or too dry due to fluctuating humidification levels. It also prevents the fragrance concentration from fluctuating, which could stimulate the nerves or fail to achieve the desired sleep-aiding effect, thus improving the sleep-aiding effect of the device.

[0046] In this embodiment, the drive mechanism 2 includes a drive chamber 21. A water intake chamber is provided on the outer periphery of the upper inner part of the drive chamber 21. Rotary shafts 22 are rotatably connected to both inner sides of the drive chamber 21. Two drive gears 23 are fixedly connected to the lower middle part of the right-side drive shaft 22. A drive gear 24 is fixedly connected to the outer periphery of the upper middle part of the left-side drive gear 23. A drive gear 25 is meshed with the right side of the drive gear 24. A rotating shaft 26 is fixedly connected to the middle part of the drive gear 25. A rotating shaft 26 is fixedly connected to the upper end of the rotating shaft 26. Disk 1 27, magnetic blocks 28 are evenly distributed on its outer periphery, iron nail ring 213 is fixedly connected to the upper outer periphery of drive chamber 21, connecting plates are evenly distributed on the upper outer periphery of drive chamber 21, and turntable 29 is rotatably connected to the upper end of the connecting plates near drive chamber 21, magnetic blocks 210 are evenly distributed on its outer periphery, and drive gear 6 211 is fixedly connected to the lower end of turntable 29, and drive gear 4 212 is meshed on the side of drive gear 6 211 away from drive chamber 21.

[0047] In this embodiment, the upper drive gear 23 meshes with the interior of the rotating seat 8, the lower drive gear 23 meshes with the interior of the impeller 7, the outer circumference of the middle part of the rotating shaft 26 is rotatably connected to the upper middle opening of the drive chamber 21, and the upper end of the speed regulating sleeve shaft 516 is sleeved on the lower end of the rotating shaft 22.

[0048] In this embodiment, the spice storage mechanism 4 includes a spice chamber 41, the upper end of which is threadedly connected to a round cover plate 42, and the outer periphery of the round cover plate 42 is evenly distributed with through holes 43. The spice storage tank 44 is fixedly connected inside the spice chamber 41, and spice compression blocks 45 are evenly distributed inside the spice storage tank 44.

[0049] In this embodiment, the water droplet launching mechanism 3 includes eight mounting plates 31. Each mounting plate 31 has a water outlet chamber 32 fixedly connected to its upper end. Each water outlet chamber 32 has a spray pipe 33 fixedly connected to its opening on the side away from the drive chamber 21. Each water outlet chamber 32 has a connecting pipe 36 fixedly connected to its opening on the side closer to the drive chamber 21. Each water outlet chamber 32 has a launching blade 34 rotatably connected inside its interior. Each launching blade 34 has a rotating shaft 35 fixedly connected to its middle part.

[0050] In this embodiment, the lower end of the connecting water pipe 13 is connected to the inside of the water intake chamber, the upper end of the connecting pipe 36 is connected to the inside of the water intake chamber, and the middle part of the drive gear four 212 is fixedly connected to the upper end of the rotating shaft three 35.

[0051] Specifically, rotating knob 55 starts the micro motor 511 via mechanical timer 54. This motor, through continuously variable speed wheel 510 and rollers 59 in adjusting sleeve 58, drives continuously variable speed wheels 512 on both sides to rotate. This, in turn, drives bevel gears 514 on both sides via drive shaft 513. These bevel gears 515 then drive speed regulating sleeve shafts 516 on both sides to rotate, which in turn drive drive gears 24 and 23 on both sides via rotating shaft 22. At this time, drive gear 23 drives the upper and lower impellers 7 and the vibrating plates 9 on the outer periphery of the rotating seat 8 to rotate. Drive gear 24, through drive gear 3 25 and rotating shaft 2 26, drives turntable 27 to rotate. When the magnetic block 28 on the outer periphery of disk 27 rotates, it cuts the magnetic field lines through the iron nail in the iron nail ring 213, causing all the rotating disks 29 to rotate due to the change in magnetic field lines via the magnetic block 210. Then, through the drive gear 6 211 and drive gear 4 212, all the rotating shafts 35 rotate, which in turn drives all the emitting blades 34 to rotate inside the water outlet chamber 32. After the clean water enters the water outlet chamber 32 through the connecting pipe 36, it is collected by the grooves of the emitting blades 34. Then, the centrifugal force generated by the rotation of the emitting blades 34 throws it out from the spray pipe 33, forming water droplets that hit the side of the vibrating plate 9, creating white noise to help with sleep. Then, all the cone-shaped amplifiers 14 focus the white noise. This system allows white noise to be output from the internal amplifier chamber 11, simulating the sound of raindrops falling on different materials and reaching the patient's ear. Through the coordination of the timing and speed control mechanism 5, the drive mechanism 2, and the water droplet emission mechanism 3, water droplets are emitted from eight directions, striking the vibrating plates 9 made of different materials. Since all the vibrating plates 9 are constantly rotating, different types of white noise are generated, simulating the white noise produced when raindrops fall on different materials due to changes in wind direction. The generated white noise is focused by the cone-shaped amplifier 14 and delivered to the patient's ear, allowing the patient to continuously listen to the realistic white noise simulating raindrops falling on different materials to fall asleep, avoiding the discomfort some patients experience with certain types of noise. The electronic sounds played by the amplifier are not sensitive enough, resulting in poor sleep-aiding effect. At the same time, after the water droplets hit the vibrating plate 9, some of them stick to the side of the vibrating plate 9 and drip down to the outer periphery of the round cover plate 42. They drip down through the through hole 43 to the upper end of the fragrance compression block 45. After absorbing water, the fragrance compression block 45 volatilizes and releases sleep-aiding fragrance, which enters the interior of the amplifier chamber 11 through the through hole 43. At the same time, another part of the water droplets will be atomized after impact. At this time, the fan wheel 7 rotates and draws in gas from the air inlet 16. After mixing with the sleep-aiding fragrance, it carries the atomized water droplets and sprays them out from the mist outlet 15 at the top. This not only has a humidifying effect, simulating the air humidity on a rainy day, but the volatilized fragrance also has a sleep-aiding effect.

[0052] It should be noted that the mechanical timer 54 adopts the same internal structure as a mechanical timer for a fan disclosed in CN2082455U, and is electrically connected to the micro motor 511. The micro motor 511 adopts a quiet micro motor disclosed in CN218897141U. All rotating parts are connected to their connecting parts through a silent bearing disclosed in CN221097187U. The lower outer periphery of the spice chamber 41 is evenly distributed with sponge pads, so that the sleep aid device produces [something] during operation. The mechanical noise is extremely low. The fragrance compression block 45 is made of dried lavender, Roman chamomile, valerian, and sandalwood, which are ground into powder, mixed with water in a certain proportion, and then dried and shaped. When it comes into contact with water, it easily releases a sleep-inducing fragrance. Patients can soothe their nerves through their sense of smell. The materials and heights of the adjacent vibrating plates 9 are different. The materials are mainly stone, glass, and plastic. When water droplets hit the side of the vibrating plate 9, different noises will be generated. Moreover, the heights and materials of the vibrating plates 9 hit by water droplets from eight directions are different, so as to generate different white noises, simulating the sound of raindrops falling on different materials on a rainy day.

[0053] Working principle: First, remove the water storage mechanism 6, open the vent cover 62, add clean water into the water storage tank 61, align the water outlet sleeve 63 with the connecting water inlet 12 at the upper end of the amplifier chamber 11, and put the water storage mechanism 6 back in. At this time, the sealing cover 64 is lifted by the connecting water inlet 12, allowing clean water to enter the water inlet chamber at the upper end of the drive chamber 21 through the connecting water inlet 12 and the connecting water pipe 13. Turn the knob 55 to start the micro motor 511 through the mechanical timer 54. The continuously variable speed wheel 510 and the roller 59 in the adjusting bushing 58 drive the continuously variable speed wheel 512 on both sides to rotate, thereby driving the bevel gear 514 on both sides to rotate through the drive shaft 513, and then driving the speed regulating sleeve shaft 516 on both sides to rotate through the bevel gear 515, and then through... The rotating shaft 22 drives the two drive gears 24 and 23 on both sides to rotate. At this time, the drive gear 23 drives the upper and lower wind turbines 7 and the vibrating plates 9 on the outer periphery of the rotating seat 8 to rotate. The drive gear 24 drives the turntable 27 to rotate through the drive gear 3 25 and the rotating shaft 26. When the turntable 27 rotates, the magnetic block 28 on the outer periphery cuts the magnetic field lines through the iron nail in the iron nail ring 213, causing all the turntables 29 to rotate through the magnetic block 210 due to the change of magnetic field lines. Then, the drive gear 6 211 and the drive gear 4 212 drive all the rotating shafts 35 to rotate, thereby driving all the launching blades 34 to rotate inside the water outlet chamber 32. After the clean water enters the water outlet chamber 32 through the connecting pipe 36, it is collected by the grooves of the launching blades 34. The centrifugal force generated by the rotation of the launching blade 34 ejects water droplets from the spray pipe 33, which then impact the side of the vibrating plate 9, creating white noise to aid sleep. All the conical amplifiers 14 then focus the white noise, allowing it to be output from inside the amplification chamber 11, simulating the sound of raindrops falling on different materials and reaching the patient's ear. Through the coordination of the timing and speed adjustment mechanism 5, the drive mechanism 2, and the water droplet launching mechanism 3, water droplets are launched from eight directions to impact the vibrating plates 9 of different materials. Since all the vibrating plates 9 are constantly rotating, they generate different types of white noise, simulating the white noise produced by raindrops falling on different materials due to changes in wind direction. The generated white noise is then focused by the conical amplifiers 14 and delivered to the patient's ear. The device is placed inside the ear, allowing patients to continuously listen to realistic white noise simulating raindrops falling on different materials to help them sleep. This avoids the situation where some patients are insensitive to electronic sounds played by the player, resulting in poor sleep aid effects. Simultaneously, after the water droplets hit the vibrating plate 9, some adhere to the side of the vibrating plate 9 and drip down to the outer periphery of the round cover plate 42, then drip through the through-hole 43 onto the upper end of the fragrance compression block 45. The fragrance compression block 45 absorbs water and releases a sleep-aiding aroma, which enters the sound chamber 11 through the through-hole 43. At the same time, another portion of the water droplets atomizes upon impact. Meanwhile, the rotating fan wheel 7 draws in air through the air inlet 16, which mixes with the sleep-aiding aroma and, carrying the atomized water droplets, sprays them out through the mist outlet 15 at the top, not only humidifying the air but also simulating the humidity of a rainy day.Furthermore, the emitted aroma can also aid sleep. When the mechanical timer 54 starts the micro motor 511, it drives the input end of the reducer 53 to rotate. At this time, the speed control lever 52 drives the two drive gears 57 on both sides to rotate via the drive gear 7 56. This, in turn, adjusts the rollers 59 on both sides to rotate in opposite directions via the adjusting sleeve 58. This results in the continuously variable speed wheel 1 510 driving the left continuously variable speed wheel 2 512 to rotate quickly in the initial stage, while the right continuously variable speed wheel 2 512 rotates slowly. This also results in more water droplets being emitted and a greater impact force due to centrifugal force in the initial stage of using the sleep aid device, simulating a heavy rain scene at the beginning. In the later stages of sleep aid, the white noise gradually thins out and the volume gradually decreases, which is beneficial for the patient to fall asleep more easily. Simultaneously, the right continuously variable speed wheel 2 512 rotates slowly in the initial stage and gradually increases its speed in the later stages of sleep aid. The speed of the impeller 7 gradually increases the rotational speed of all the vibrating plates 9, resulting in a high density of water droplets impacting the same vibrating plate 9 in the initial stage. This further enhances the density of raindrops falling on the same material under varying rainfall conditions. In the initial stage, due to the high density and impact force of the water droplets, more atomized water droplets are generated, resulting in more droplets falling onto the fragrance compression block 45. At this time, the impeller 7 rotates slowly. Later, as the number of atomized water droplets decreases, the number of droplets falling onto the fragrance compression block 45 also gradually decreases, and the rotational speed of the impeller 7 gradually increases. This ensures that the amount of atomized particles and sleep-aiding fragrance sprayed remains constant during the use of the sleep aid device. This maintains a consistent level of air humidification and fragrance output, preventing excessively humid or dry air due to fluctuating humidification levels, and avoiding inconsistent fragrance concentrations that could stimulate the nerves or fail to achieve the desired sleep-aiding effect, thus improving the sleep-aiding effect of the device.
