Description

Technical Field

[0001] The invention belongs to the technical field of medical equipment, and in particular relates to a reminder for preventing myopia. Background Art

[0002] Myopia is the disease most involved in the health of adolescents and has become a social problem that must arouse everyone's common concern. Myopia in students often begins in school age, between 6 and 15 years old. The formation process of myopia in students mainly occurs during primary and secondary school years. Due to lack of attention to eye hygiene, incorrect sitting posture, staggering, or even lying on the table, over time, the eye axis becomes longer and myopia is formed.

[0003] Currently, most methods of correcting myopia are through parental education and the use of straps fixed on the child's back. The straps prevent the child from hunching over through stretching. However, parents are required to help wear the straps during use, which is inconvenient to use and does not serve as a good reminder. In addition, when children are studying, the intensity of external light will change. Studying in insufficient light will aggravate myopia.

[0004] To this end, we provide a reminder for preventing myopia to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to provide a reminder device for preventing myopia. Through the cooperation of a reminder component and a hot compress component, the myopia correction method in the prior art is solved, which lacks the function of reminding children of the writing distance, and the myopia problem will be aggravated if children study in insufficient light.

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The present invention is a reminder device for preventing myopia, comprising a headband, one side of the headband is fixedly connected with a strap, the front side of the headband is installed with a fixing seat, and the fixing seat is provided with an infrared distance sensor inside;

[0008] A prompt component is arranged on the front side of the fixing seat, and the prompt component includes a speaker, and the speaker is installed on the front side of the fixing seat, a vibration motor is installed inside the fixing seat, and a light sensor is installed on the top of the fixing seat;

[0009] A hot compress assembly is arranged inside the headband, and the hot compress assembly includes an isolation pad, the isolation pad is fixedly connected to the rear side of the headband, and a heater is installed on one side of the isolation pad.

[0010] The present invention is further configured such that a sweat-absorbing belt is provided at the rear side of the headband, and adhesive tapes are fixedly connected to the top and bottom of the sweat-absorbing belt.

[0011] The present invention is further configured such that a forehead thermometer is fixedly connected to the rear side of the headband, and there are two groups of heaters.

[0012] The present invention is further configured such that the other end of the strap is fixedly connected to a first Velcro, and the surface of the strap is fixedly connected to a second Velcro.

[0013] The present invention is further configured such that a fixing ring is sleeved on the surface of the binding strap, and one side of the fixing ring is fixedly connected to the head ring.

[0014] The present invention is further configured such that a storage battery is installed inside the fixing seat, and a charging port is installed on one side of the storage battery.

[0015] The present invention is further configured such that both sides of the infrared distance sensor are fixedly connected with a rotating shaft, the other end of the rotating shaft is movably connected to the inner wall of the fixing seat, and a friction pad is fixedly connected to the surface of the rotating shaft.

[0016] The present invention has the following beneficial effects:

[0017] The present invention can detect the distance between the user and the table through the setting of the prompt component after the user wears the headband through the infrared distance sensor. When the user keeps a close distance to the table for a long time, the speaker can broadcast a sound to announce the current distance, and the vibration motor can vibrate to increase the reminder effect and correct the user to maintain the correct writing distance. Through the setting of the hot compress component, when the user becomes tired, the headband can be moved to the eye position and the heater can be started for hot compress, which helps to relieve eye fatigue.

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Specific embodiment 1

[0027] See also Figure 1-4 The present invention is a reminder device for preventing myopia, comprising a headband 1, a strap 2 fixedly connected to one side of the headband 1, a fixing seat 3 installed on the front side of the headband 1, an infrared distance sensor 4 is arranged inside the fixing seat 3; a reminder component is arranged on the front side of the fixing seat 3, the reminder component comprises a speaker 5, the speaker 5 is installed on the front side of the fixing seat 3, a vibration motor 6 is installed inside the fixing seat 3, and a light sensor 7 is installed on the top of the fixing seat 3; a hot compress component is arranged inside the headband 1, the hot compress component comprises an isolation pad 8, the isolation pad 8 is fixedly connected to the rear side of the headband 1, and a heater 9 is installed on one side of the isolation pad 8.

[0028] Specifically: The infrared distance sensor 4 can detect the distance between an object and the sensor. Its principle is based on the reflection and time-of-flight measurement of infrared rays. When the sensor emits infrared rays, it measures the time or reflection intensity from the sensor to the object and back, thereby calculating the distance between the object and the sensor. The distance between the child's eyes and the table can be detected. The light sensor 7 can detect the intensity of external light. When the ambient light is insufficient, the speaker 5 can be used to remind the child and guide the optimal outdoor and learning environment. Specific embodiment 2

[0030] See also Figure 1-4 On the basis of the specific embodiment 1, a sweat-absorbent belt 10 is arranged on the rear side of the headband 1, and adhesive tape 11 is fixedly connected to the top and bottom of the sweat-absorbent belt 10, a forehead thermometer 12 is fixedly connected to the rear side of the headband 1, there are two groups of heaters 9, a first Velcro 13 is fixedly connected to the other end of the strap 2, a second Velcro 14 is fixedly connected to the surface of the strap 2, a fixing ring 15 is sleeved on the surface of the strap 2, one side of the fixing ring 15 is fixedly connected to the headband 1, a battery 16 is installed inside the fixing seat 3, a charging port 17 is installed on one side of the battery 16, a rotating shaft 18 is fixedly connected to both sides of the infrared distance sensor 4, the other end of the rotating shaft 18 is movably connected to the inner wall of the fixing seat 3, and a friction pad 19 is fixedly connected to the surface of the rotating shaft 18.

[0031] Specifically: the heater 9 can provide heat by electric heating, which is convenient for hot compressing the child's eyes. The sweat-absorbent belt 10 is fixed to the headband 1 by the tape 11, which can absorb the sweat on the child's head. At the same time, it can be disassembled, replaced and cleaned after using it for a period of time. The forehead thermometer 12 can detect the child's body temperature and serve as a reminder. The friction pad 19 contacts the inner wall of the fixing seat 3, and can limit the rotation of the rotating shaft 18 by friction, so that the position of the infrared distance sensor 4 can be adjusted and fixed.

[0032] The working principle of the present invention is as follows: the user first fits the headband 1 to the forehead, then rotates the strap 2 and inserts the strap 2 into the fixing ring 15, and rotates the strap 2 again to make the first Velcro 13 and the second Velcro 14 adhere to each other, thereby completing the fixing of the headband 1;

[0033] When the user sits in front of the table, the infrared distance sensor 4 emits light to detect the distance between the table and the sensor as standard data for the correct posture. When the user hunches, the infrared distance sensor 4 transmits a signal to the external controller and starts the speaker 5 to broadcast the current distance, and vibrates through the vibration motor 6 to increase the reminder effect and correct the user to maintain the correct writing distance. By monitoring the distance between the head and the table, the posture of the child can be analyzed, such as whether the sitting posture is correct or whether the head is lowered too much, so as to remind or adjust the posture, which helps to protect the health of the child's neck and spine;

[0034] After the user maintains the correct posture for a set period of time, the speaker 5 can be used to remind the user to rest. At the same time, the user can move the headband 1 downward to the eye position and start the heater 9 to apply hot compress to the user's eyes. Hot compress can promote blood circulation around the eyes, relax the muscles around the eyes, and help relieve eye fatigue and dryness caused by long-term use of electronic devices or concentration.
