Description

Technical Field

[0001] The present invention relates to the technical field of children's eye protection, and in particular to equipment for monitoring and improving children's eye habits around the clock. Background Art

[0002] Visual fatigue, also known as eye strain, refers to eye fatigue caused by excessive use of the eyes when engaged in close-up work or study. The main clinical manifestations are blurred vision, intolerance to long-term vision, dry and uncomfortable eyes, soreness and tearing, headache and dizziness. It is a syndrome based on subjective eye symptoms, in which eye or systemic factors are intertwined with mental factors. Its causes are complex and diverse, and are related to mental, psychological, environmental, personal physique, diet and lifestyle factors. It is the result of the combined action of multiple factors. In recent years, with the widespread popularization of video terminals such as computers and smart phones, the incidence of visual fatigue has been gradually increasing. The physical fatigue and pain of patients and the negative emotions such as anxiety, irritability, and insomnia caused by them have seriously affected their work and study and reduced their quality of life. In addition, the age of patients with visual fatigue is increasing. The characteristics of visual fatigue are that they are mainly subjective symptoms, and the symptoms worsen after using the eyes and are alleviated or disappear after rest.

[0003] Children may forget the time when they sit at a desk to study or watch electronic devices. Using the eyes for a long time will cause eye fatigue, and frequent use of the eyes will cause vision loss. Some experts point out that children should relax their eyes properly after continuous close-range use of their eyes. This can effectively prevent children's vision loss.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] Embodiment 1

[0027] The present invention provides a technical solution: a device for monitoring and improving children's eye habits around the clock, comprising a waist belt 1 and a shoulder strap 2, the waist belt 1 being provided with a correction mechanism for correcting children's posture, the correction mechanism comprising a motor 12, a mounting seat 11 being fixedly connected to the waist belt 1, a rotating shaft 13 being rotatably connected to the mounting seat 11, the rotating shaft 13 being fixedly connected to the output end of the motor 12, the motor 12 being fixedly connected to the mounting seat 11, a ring 101 being fixedly connected to the waist belt 1, a spring 102 being fixedly connected between the ring 101 and the rotating shaft 13, a drawstring 131 being wound around the rotating shaft 13, a connecting plate 21 being fixedly connected to the shoulder strap 2, an end of the drawstring 131 away from the rotating shaft 13 being fixedly connected to the connecting plate 21, a tough plate 22 being fixedly connected to the connecting plate 21, and the bottom of the tough plate 22 being rotatably connected to the waist belt 1.

[0028] Reference Figure 1 , Figure 2 , Figure 5 and Figure 6 When a child bends down to look at an electronic device or studies for a long time, the shoulder strap 2 has pulled the shaft 13 to rotate through the pull rope 131. Figure 5 and Figure 6 When the pull rope 131 pulls the rotating shaft 13, the rotating shaft 13 rotates clockwise. At this time, the first gear 14 fixedly connected to the rotating shaft 13 rotates clockwise synchronously with the rotating shaft 13, and then the first rack 15 located on the upper part of the first gear 14 and meshing with the first gear 14 can be driven by the first gear 14 to slide in the direction of the belt 1, that is, at this time, the first rack 15 approaches the delayed pressure-sensitive switch 19. Since the cylinder 16 is fixedly connected to the first rack 15, and the pressing rod 17 is slidably connected to the cylinder 16, and the two ends of the first spring 18 knotted on the pressing rod 17 are fixedly connected to the cylinder 16 and the pressing rod 17, when the first rack 15 moves toward the delayed pressure-sensitive switch 19, the pressing rod 17 can synchronously move the delayed pressure-sensitive switch 19, refer to Figure 6, the distance between the pressing rod 17 and the delayed pressure-sensitive switch 19 is relatively short. The movement of the first rack 15 enables the cylinder 16 to slide relative to the pressing rod 17 after the pressing rod 17 contacts the delayed pressure-sensitive switch 19. At this time, the first spring 18 is also compressed, and the pressing rod 17 is still in contact with the delayed pressure-sensitive switch 19. The amplitude of the child's straightening is small, the length of the pull rope 131 stored in the rotating shaft 13 is also small, and then the rotation angle of the rotating shaft 13 is also small, and then the rotation angle of the first gear 14 is also small, and then the distance that the first rack 15 slides away from the delayed pressure-sensitive switch 19 is also small. At this time, the pressing rod 17 will still apply pressure to the delayed pressure-sensitive switch 19, thereby avoiding the delayed pressure-sensitive switch 19 being pressed by the pressing rod 17 when the child is moving but has not adjusted his posture.

[0029] Furthermore, the correction mechanism also includes a first gear 14, which is coaxially fixedly connected to the rotating shaft 13, and a delayed pressure-sensitive switch 19 for controlling the motor 12 is provided on the mounting seat 11. A first rack 15 meshing with the first gear 14 is slidably connected to the mounting seat 11, and a cylinder 16 is fixedly connected to the first rack 15. A pressing rod 17 is slidably connected in the cylinder 16, and the pressing rod 17 intermittently abuts against the delayed pressure-sensitive switch 19. A first spring 18 is knotted on the pressing rod 17, and both ends of the first spring 18 are respectively fixedly connected to the cylinder 16 and the pressing rod 17.

[0030] The motor 12 is powered by a battery (not shown in the figure). The triggering time of the delayed pressure-sensitive switch 19 is adjusted according to the eye-use time of children of different age groups. When the delayed pressure-sensitive switch 19 is pressed by the pressing rod 17 for a time set by the delayed pressure-sensitive switch 19 (such as after 20 minutes), the delayed pressure-sensitive switch 19 will control the motor 12 to run for 20 to 30 seconds. At this time, the motor 12 can drive the rotating shaft 13 to rotate. Figure 5 In the state, the pull cord 131 rotates counterclockwise, and at this time, the pull cord 131 is forcibly stored on the rotating shaft 13, and the pull cord 131 is fixedly connected to the shoulder strap 2. The shoulder strap 2 is worn on the child's shoulders, and the pull of the pull cord 131 forces the child to straighten his waist and chest. Figure 2 In the initial state, the bending direction of the flexible plate 22 is also toward the child's back. At the same time, the flexible plate 22 will also bend toward the child's back due to the storage of the pull rope 131, further straightening the child's back.

[0031] Embodiment 2

[0032] On the basis of the first embodiment, further, a lifting mechanism for enabling the child to raise his head is provided on the correction mechanism, and the lifting mechanism includes an arc-shaped airbag 43, and the arc-shaped airbag 43 is fixedly connected to the shoulder strap 2, and the arc-shaped airbag 43 is in contact with the human body.

[0033] Reference Figure 1 , Figure 2and Figure 7 When the motor 12 is not in working condition, when the child bends over, the pulling of the pull rope 131 causes the rotation of the rotating shaft 13 to overcome the force of the spring 102, and a pressure valve 42 is provided on the air pipe 41 connecting the arc-shaped air bag 43 and the cylindrical air bag 4. The force of the spring 102 will not cause the pressure between the body and the arc-shaped air bag 43 to exceed the limit of the pressure valve 42 when the child bends over, and thus under normal circumstances, the gas in the arc-shaped air bag 43 will not be transferred to the cylindrical air bag 4.

[0034] Furthermore, the lifting mechanism also includes a cylindrical airbag 4 , to which an air pipe 41 is fixedly connected and communicates with the arc-shaped airbag 43 through the air pipe 41 , and a pressure valve 42 is provided on the air pipe 41 .

[0035] Reference Figure 1 , Figure 2 and Figure 7 When the motor 12 drives the rotating shaft 13 to rotate, the drawstring 131 can be stored at a larger length. At this time, the force exerted by the shoulder strap 2 and the child's body on the arc-shaped airbag 43 will make the pressure inside the arc-shaped airbag 43 exceed the limit of the pressure valve 42. At this time, the gas in the arc-shaped airbag 43 can be transferred to the cylindrical airbag 4 through the trachea 41, and the cylindrical airbag 4 is located at the bottom of the child's chin. The inflated cylindrical airbag 4 can lift the child's chin and make the child's head tilt back, thereby preventing the child from continuing to use his eyes.

[0036] Embodiment 3

[0037] On the basis of the second embodiment, further, the lifting mechanism is provided with a relaxation mechanism for relaxing the eyes of children, the relaxation mechanism includes a mounting plate 23, the mounting plate 23 is slidably connected to the connecting plate 21, the upper part of the mounting plate 23 is fixedly connected to the head support 24, the lower part of the mounting plate 23 is fixedly connected to the telescopic rod 26, the tough plate 22 is fixedly connected to the support plate 221, the bottom of the telescopic rod 26 is fixedly connected to the support plate 221, the telescopic rod 26 is looped with a second spring 27, and the two ends of the second spring 27 are respectively fixedly connected to the mounting plate 23 and the support plate 221.

[0038] Reference Figure 1-Figure 4 When the child's head tilts back, the back of the child's head can contact the head support 24 and exert a downward force on the head support 24. At this time, the mounting plate 23 fixedly connected to the head support 24 can overcome the elastic force of the second spring 27 and move downward, and then the second rack 25 fixedly connected to the mounting plate 23 moves downward, and then the second gear 28 meshing with the second rack 25 can rotate. Figure 3There are two sets of second racks 25 and second gears 28, and the two sets are located on both sides of the mounting plate 23, and the nozzle 3 is fixedly connected to the second gear 28 through a hollow rod 32, so that when the mounting plate 23 moves downward, the two nozzles 3 can be swung upward in a direction away from the tough plate 22.

[0039] Furthermore, the relaxation mechanism also includes a second gear 28, which is rotatably connected to the connecting plate 21, and a second rack 25 is fixedly connected to the mounting plate 23, the second rack 25 is meshed with the second gear 28, a hollow rod 32 is coaxially fixedly connected to the second gear 28, a nozzle 3 is fixedly connected to the hollow rod 32, an end of the nozzle 3 away from the hollow rod 32 is rotatably connected to an atomizing nozzle 31, and the nozzle 3 is communicated with the internal space of the hollow rod 32.

[0040] Reference Figure 1-Figure 4 When the mounting plate 23 slides down to the lowest position, the nozzle 3 swings to a vertical state. When the nozzle 3 swings to a vertical state, the hole on the hollow rod 32 fixedly connected to the nozzle 3 is also connected to the hole on the sleeve 291 that cooperates with the discharge pipe 29. At this time, the medicine for relieving eye fatigue in the high-pressure box 222 can be pressurized and sprayed out through the discharge pipe 29, the hollow rod 32, the nozzle 3 and the atomizing nozzle 31 in sequence. The atomizing nozzle 31 is rotatably connected to the nozzle 3, and the atomizing nozzle 31 can be manually twisted so that the medicine sprayed from the atomizing nozzle 31 can be sprayed toward the eye position.

[0041] Furthermore, the relaxation mechanism also includes a ring 291, which is rotatably connected to the hollow rod 32, and the inner wall of the ring 291 is in contact with the outer wall of the hollow rod 32. The ring 291 is fixedly connected to the discharge pipe 29, and the ring 291 is provided with a through hole connected to the discharge pipe 29. The hollow rod 32 is provided with a through hole intermittently connected to the discharge pipe 29. The tough plate 22 is fixedly connected to a high-pressure box 222 for containing eye fatigue relieving medicine, and the end of the discharge pipe 29 away from the ring 291 passes through the top plate of the high-pressure box 222 and extends into the interior thereof.

[0042] Reference Figure 1-Figure 3 When the medicine mist is sprayed toward the child's eyes, the child will blink due to the human body's conditioned reflex, and blinking can relieve eye fatigue. At the same time, since the medicine mist is atomized and sprayed through the atomizing nozzle 31, a small part of the medicine mist can enter the eyes, further relieving the child's eye fatigue.

[0043] Furthermore, there are two nozzles 3 , both of which are rotatably connected to an atomizing nozzle 31 , and the two nozzles 3 are symmetrically distributed on both sides of the mounting plate 23 .

[0044] Reference Figure 1-Figure 3The two atomizing nozzles 31 correspond to the children's eyes. The pressure of the high-pressure box 222 is constant. When the pressure inside the high-pressure box 222 decreases, the liquid medicine in the high-pressure box 222 will no longer be sprayed out. By setting a mechanism similar to the inflation of a gas lighter on the high-pressure box 222, the liquid medicine in the high-pressure box 222 can be replenished. After the replenishment amount of the liquid medicine is almost enough, air is injected into the high-pressure box 222 to increase the pressure inside the high-pressure box 222.

[0045] Working principle: When using the device for monitoring and improving children's eye habits around the clock, open the waist belt 1 and put it on the child. The shoulder strap 2 is connected first with Velcro. First, open the shoulder strap 2, then let the child's head pass between the connecting plate 21 and the cylindrical airbag 4, then pass the shoulder strap 2 around the child's armpit and stick the shoulder strap 2 first with Velcro, so that the arc-shaped airbag 43 faces the front of the child, adjust the position of the shoulder strap 2, so that the cylindrical airbag 4 is under the child's chin, so that the height of the connecting plate 21 is roughly at the position of the shoulder blade, and at this time, the toughness plate 22 fits with the child's back spine;

[0046] Since the toughness plate 22 has a certain toughness, the child can bend over during use, and the toughness plate 22 can also apply a certain thrust to the child's back, so that the child can keep the child in a state of not bending over. When the motor 12 is not powered, the shaft 13 connected to the output end of the motor 12 can rotate. When the child bends over, the shoulder position will tilt forward. At this time, the shoulder strap 2 can pull the shaft 13 to rotate through the pull rope 131, and the shaft 13 is fixedly connected to the ring 101 through the spring 102, and the ring 101 is fixedly connected to the belt 1. When the pull rope 131 applies tension to the shaft 13, the spring 102 can have elastic potential energy when the shaft 13 rotates. When the child returns to a normal posture from the bending state, the force of the spring 102 can reverse the shaft 13 and store the pull rope 131, thereby avoiding the problem of entanglement caused by excessive release of the pull rope 131.

[0047] When a child bends down to look at an electronic device or studies for a long time, the shoulder strap 2 has pulled the shaft 13 to rotate through the pull rope 131. Figure 5 and Figure 6When the pull rope 131 pulls the rotating shaft 13, the rotating shaft 13 rotates clockwise. At this time, the first gear 14 fixedly connected to the rotating shaft 13 rotates clockwise synchronously with the rotating shaft 13, and then the first rack 15 located on the upper part of the first gear 14 and meshing with the first gear 14 can be driven by the first gear 14 to slide in the direction of the belt 1, that is, at this time, the first rack 15 approaches the delayed pressure-sensitive switch 19. Since the cylinder 16 is fixedly connected to the first rack 15, and the pressing rod 17 is slidably connected to the cylinder 16, and the two ends of the first spring 18 knotted on the pressing rod 17 are fixedly connected to the cylinder 16 and the pressing rod 17, when the first rack 15 moves toward the delayed pressure-sensitive switch 19, the pressing rod 17 can synchronously move the delayed pressure-sensitive switch 19, refer to Figure 6 , the distance between the pressing rod 17 and the delayed pressure-sensitive switch 19 is short, and the movement of the first rack 15 enables the cylinder 16 to slide relative to the pressing rod 17 after the pressing rod 17 contacts the delayed pressure-sensitive switch 19. At this time, the first spring 18 is also compressed, and the pressing rod 17 is still in contact with the delayed pressure-sensitive switch 19. The amplitude of the child's straightening is small, and the length of the pull rope 131 stored in the shaft 13 is also small, and then the rotation angle of the shaft 13 is also small, and then the rotation angle of the first gear 14 is also small, and then the sliding distance of the first rack 15 away from the delayed pressure-sensitive switch 19 is also small. At this time, the pressing rod 17 will still apply pressure to the delayed pressure-sensitive switch 19, thereby preventing the delayed pressure-sensitive switch 19 from being pressed by the pressing rod 17 when the child is moving but has not adjusted his posture;

[0048] The motor 12 is powered by a battery (not shown in the figure). The triggering time of the delayed pressure-sensitive switch 19 is adjusted according to the eye-use time of children of different age groups. When the delayed pressure-sensitive switch 19 is pressed by the pressing rod 17 for a set time (such as twenty minutes), the delayed pressure-sensitive switch 19 will control the motor 12 to run for twenty to thirty seconds. At this time, the motor 12 can drive the rotating shaft 13 to rotate. Figure 5 In the state, the pull cord 131 rotates counterclockwise, and at this time, the pull cord 131 is forcibly stored on the rotating shaft 13, and the pull cord 131 is fixedly connected to the shoulder strap 2. The shoulder strap 2 is worn on the child's shoulders, and the pull of the pull cord 131 forces the child to straighten his waist and chest. Figure 2 In the initial state, the bending direction of the flexible plate 22 is also toward the child's back. At the same time, the flexible plate 22 will bend toward the child's back due to the storage of the drawstring 131, further straightening the child's back.

[0049] When the motor 12 is not in a working state, the pulling of the pull rope 131 by the child when bending over causes the rotation of the shaft 13 to overcome the force of the spring 102, and a pressure valve 42 is provided on the air pipe 41 connecting the arc-shaped airbag 43 and the cylindrical airbag 4. The force of the spring 102 will not cause the pressure between the body and the arc-shaped airbag 43 to exceed the limit of the pressure valve 42 when the child bends over, and then under normal circumstances, the gas in the arc-shaped airbag 43 will not be transferred to the cylindrical airbag 4, and the motor 12 drives the shaft 13 to rotate. When the child is in motion, the drawstring 131 can be stored at a greater length, and the force exerted by the shoulder strap 2 and the child's body on the arc-shaped airbag 43 will make the pressure inside the arc-shaped airbag 43 exceed the limit of the pressure valve 42, and the gas in the arc-shaped airbag 43 can be transferred to the cylindrical airbag 4 through the trachea 41, and the cylindrical airbag 4 is located at the bottom of the child's chin, and the inflated cylindrical airbag 4 can lift the child's chin to make the child's head tilt back, thereby preventing the child from continuing to use his eyes;

[0050] When the child's head tilts back, the back of the child's head can contact the headrest 24 and exert a downward force on the headrest 24. At this time, the mounting plate 23 fixedly connected to the headrest 24 can overcome the elastic force of the second spring 27 and move downward, so that the second rack 25 fixedly connected to the mounting plate 23 moves downward, and the second gear 28 meshing with the second rack 25 can rotate. Figure 3 , two groups of second racks 25 and second gears 28 are provided, and the two groups are located on both sides of the mounting plate 23, and the nozzle 3 is fixedly connected to the second gear 28 through a hollow rod 32, so that when the mounting plate 23 moves downward, the two nozzles 3 can be swung upward in a direction away from the tough plate 22, and when the mounting plate 23 slides down to the lowest position, the nozzle 3 swings to a vertical state, and when the nozzle 3 swings to a vertical state, the hole on the hollow rod 32 fixedly connected to the nozzle 3 is also connected to the hole on the collar 291 that matches the discharge pipe 29, so that at this time, the pressure in the high-pressure box 222 is relieved. The eye fatigue medicine can be pressurized and sprayed out through the discharge pipe 29, the hollow rod 32, the nozzle 3 and the atomizing nozzle 31 in sequence, and the atomizing nozzle 31 is rotatably connected to the nozzle 3, and the atomizing nozzle 31 can be manually twisted so that the medicine sprayed from the atomizing nozzle 31 can be sprayed toward the eye position. When the medicine mist is sprayed toward the child's eyes, the child will blink due to the influence of the human body's conditioned reflex, and eye fatigue can be relieved by blinking. At the same time, since the medicine mist is sprayed out after being atomized by the atomizing nozzle 31, a small part of the medicine mist can enter the eye, further relieving the child's eye fatigue.

[0051] The pressure of the high-pressure box 222 is constant. When the pressure inside the high-pressure box 222 decreases, the medicine liquid in the high-pressure box 222 will no longer spray out. By setting a mechanism similar to the inflation of a gas lighter on the high-pressure box 222, the medicine liquid in the high-pressure box 222 can be replenished. After the medicine liquid is replenished, air is injected into the high-pressure box 222 to increase the pressure inside the high-pressure box 222.

[0052] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
