[0002] With social development and increased reading time, childhood myopia has become a significant public health issue. Among the contributing factors to childhood myopia, excessively close viewing distance and poor posture are of great concern to parents. Environmental factors are the main factors influencing childhood myopia, including insufficient outdoor activity time, excessive close-up work time, incorrect reading and writing posture, and inadequate lighting, all of which can lead to myopia and dry eye problems. Summary of the Invention

[0003] The present invention aims to solve the problems existing in the prior art by providing myopia control glasses with fogging lenses, which can prevent myopia and dry eye syndrome.

[0004] The technical solution adopted by this invention to solve its technical problem is: myopia prevention glasses with fogging lenses, including a frame, an electrically controlled fogging lens, a control motherboard and a power module. The control motherboard is electrically connected to the power module and the electrically controlled fogging lens. The electrically controlled fogging lens is made of reverse PNLC material. The fog level of the electrically controlled fogging lens increases when powered on and decreases when powered off. The invention is characterized in that: a distance sensor, a camera module and a spray device are also electrically connected to the control motherboard.

[0005] The distance sensor is located on the front of the frame and is used to obtain the usage distance of the glasses. When the usage distance is less than the preset usage distance, the control board controls the power module to supply power to the electronically controlled fogging lens; otherwise, it does not supply power.

[0006] The camera module is located on the back of the lens frame and is used to acquire the blinking frequency of the eyes. When the blinking frequency is not within the preset blinking frequency range, the control motherboard controls the power module to supply power to the electronically controlled fogging lens; otherwise, it does not supply power.

[0007] The spray device is located on the upper or lower side of the frame and is used to spray mist-like eye drops into the eyes. When the blinking frequency is not within the preset blinking frequency range, the spray device sprays eye drops into the eyes once. When the wearing distance of the glasses is greater than the preset wearing distance and lasts for more than 30 minutes, the spray device sprays eye drops into the eyes once. The spraying frequency is 1-2 hours / time.

[0008] Further improvements have been made, with a preset blinking frequency range of 8-25 times / minute and a preset usage distance of 20-30cm.

[0009] Further improvements include a liquid storage pipe and an electric water pump. The electric water pump is electrically connected to the control main board. The inlet of the electric water pump is connected to the liquid storage pipe, and the inlet of the electric water pump is connected to the delivery pipe, which is connected to the spray head.

[0010] Further improvements include the electric water pump comprising a motor, a centrifugal impeller, and an impeller cavity. The centrifugal impeller is rotatably mounted inside the impeller cavity. The side wall of the impeller cavity is connected to the infusion pipe. The centrifugal impeller consists of a shaft and several centrifugal blades circumferentially distributed on the shaft. One end of the shaft is fixedly connected to the motor. The shaft has a shaft hole that communicates with the storage pipe. The side wall of the shaft has a side hole that communicates with the shaft hole. The side hole is located between adjacent centrifugal blades.

[0011] To further improve the design, the top of the liquid storage tube is equipped with a breathable filter plug, and the front of the mirror frame is equipped with a viewing window to display the liquid level of the liquid storage tube.

[0012] To further improve the design, the impeller cavity is provided with manifolds on both sides, and the manifolds are connected to the infusion pipe.

[0013] To further improve the design, guide vanes are fixedly installed on both the upper and lower sides of the axle, and centrifugal blades are located between the two guide vanes.

[0014] In a further improvement, the spray head includes a spray cap, a base, an infusion channel, and a spray hole. The spray hole and the infusion channel are respectively disposed on the spray cap and the base. The infusion channel is connected to the spray hole. An elastic sealing ring for adjusting the spray hole diameter is provided between the spray hole and the infusion channel. The spray cap and the base are connected by threads.

[0015] Further improvements include a pressure boosting tube on the infusion tubing, with an inlet and an outlet at both ends of the pressure boosting tube connecting to the infusion tubing. A core tube is installed inside the pressure boosting tube, with one end of the core tube fixedly connected to the outlet and the other end of the core tube hinged to a valve plate.

[0025] The present invention will be further described below with reference to the accompanying drawings:

[0026] See attached document Figure 1-3 The myopia control glasses with fogging capability in this embodiment 1 include a frame 1, an electrically controlled fogging lens 2, a control motherboard, and a power module. The control motherboard is electrically connected to the power module and the electrically controlled fogging lens 2. The electrically controlled fogging lens 2 is made of reverse PNLC material. The fog level of the electrically controlled fogging lens 2 increases when powered on and decreases when powered off. The feature is that a distance sensor 3, a camera module 4, and a spray device 5 are also electrically connected to the control motherboard.

[0027] The distance sensor 3 is installed on the front of the frame 1 to obtain the usage distance of the glasses; when the usage distance is less than the preset usage distance, the control motherboard controls the power module to supply power to the electronically controlled atomizing lens 2, otherwise it is not powered.

[0028] The camera module 4 is mounted on the back of the frame 1 and is used to acquire the blinking frequency of the eyes. When the blinking frequency is not within the preset blinking frequency range, the control motherboard controls the power module to supply power to the electronically controlled atomizing lens 2; otherwise, it does not supply power.

[0029] The spray device 5 is located on the upper or lower side of the frame 1 and is used to spray mist-like eye drops into the eyes. When the blinking frequency is not within the preset blinking frequency range, the spray device 5 sprays eye drops into the eyes once. When the viewing distance of the glasses is greater than the preset viewing distance and lasts for more than 30 minutes, the spray device 5 sprays eye drops into the eyes once. The spraying frequency is 1-2 hours / time.

[0030] The preset blinking frequency range is 8-25 times / minute, the preset usage distance is 20-30cm, and the default is no less than 30cm.

[0031] When the glasses are sprayed more than three times in a single use, the control board controls the power module to supply power to the electronically controlled atomizing lens 2; otherwise, no power is supplied. Limiting the number of sprays can prevent users from becoming overly reliant on the spray and using their eyes continuously.

[0032] As attached Figure 3 As shown in Example 2, based on Example 1, the spray device 5 includes a storage tube 6 and an electric water pump 7. The electric water pump 7 is electrically connected to the control board. The inlet of the electric water pump 7 is connected to the storage tube 6, and the inlet of the electric water pump 7 is connected to the delivery tube 8. The delivery tube 8 is connected to the spray head 9. The storage tube 6 stores eye drops. When spraying is needed, the control board starts the electric water pump 7, which draws out the eye drops from the storage tube 6 and delivers them to the spray head 9 through the delivery tube 8. The eye drops are then sprayed from the spray head 9 as a mist into the eye for moisturizing.

[0033] As attached Figure 4As shown in Example 3, based on Example 2, the electric water pump 7 includes a motor 10, a centrifugal impeller 11, and an impeller cavity 12. The centrifugal impeller 11 is rotatably installed inside the impeller cavity 12. The side wall of the impeller cavity 12 is connected to the infusion pipe 8. The centrifugal impeller 11 consists of a shaft 13 and several centrifugal blades 14 circumferentially distributed on the shaft 13. One end of the shaft 13 is fixedly connected to the motor 10. The shaft 13 has a shaft hole 15 communicating with the storage pipe 6. The side wall of the shaft 13 has a side hole 16 communicating with the shaft hole 15. The side hole 16 is located between adjacent centrifugal blades 14. In use, the motor 10 is energized to drive the centrifugal impeller 11 to rotate. The eye drops in the storage pipe 6 flow into the impeller cavity 12 through the shaft hole 15 and the side hole 16. When the centrifugal blades 14 rotate, they throw the eye drops in the middle to the edge, forming water pressure, which is then pumped into the spray head 9 through the infusion pipe 8 for release. The impeller cavity 12 has converging chambers 17 on both sides, which are connected to the infusion pipe 8. The converging chambers 17 can collect more water flow from the edge, reducing pressure drop. Guide vanes 18 are fixedly installed on both the upper and lower sides of the shaft 13, with centrifugal blades 14 located between the two guide vanes 18. The guide vanes 18 can close the upper and lower sides of the centrifugal blades 14, forming a channel, allowing the eye drops between adjacent centrifugal blades 14 to pass through and be thrown to the edge more quickly, improving mechanical efficiency. To avoid abrupt spraying, the motor 10 first starts at low speed for 3 seconds as a warning, then runs at high speed for 2 seconds to spray.

[0034] As attached Figure 5 As shown in Example 4, based on Example 2, the spray head includes a spray cap 19, a base 20, an infusion channel 21, and a spray orifice 22. The spray orifice 22 and the infusion channel 21 are respectively disposed on the spray cap 19 and the base 20. The infusion channel 21 is connected to the spray orifice 22. An elastic sealing ring 23 for adjusting the spray orifice diameter is provided between the spray orifice 22 and the infusion channel 21. The spray cap 19 and the base 20 are connected by threads. The eye drops from the infusion tube can flow through the infusion channel 21 to the elastic sealing ring 23, and after passing through its inner hole, they are sprayed and atomized. Tightening the spray cap 19 can compress the elastic sealing ring 23 to deform it, making its inner hole diameter smaller and improving its atomization effect. Loosening the spray cap 19 can loosen the elastic sealing ring 23, making its inner hole diameter larger and its atomized droplets larger. The elastic sealing ring 23 also has the functions of preventing loosening and leakage.

[0035] As attached Figure 6-7As shown in Example 5, based on Example 2, the infusion tube is provided with a pressure boosting tube 24. The two ends of the pressure boosting tube 24 are provided with an inlet and an outlet that connect to the infusion tube. A core tube 25 is provided inside the pressure boosting tube 24. One end of the core tube 25 is fixedly connected to the outlet, and a valve plate 26 is hinged to the other end of the core tube 25. A piston ring 27 is slidably installed between the pressure boosting tube 24 and the core tube 25. A tension spring 28 is provided between the piston ring 27 and the valve plate 26, and a compression spring 29 is provided between the piston ring 27 and the outlet. The eye drops pumped in compress the piston ring 27, causing it to move to the right. At this time, the tension spring 28 extends, and the compression spring 29 compresses, increasing the water pressure in the chamber. When the elastic force on the tension spring 28 exceeds a certain value, it drives the valve plate 26 to open. Under pressure, the liquid is instantly pushed through the core tube 25 into the spray head 9 for atomized spraying, resulting in better atomization. At this point, the tension spring 28 shortens, and the compression spring 29 compresses. The valve plate 26, under gravity or the push of the tension spring 28, closes the opening of the core tube 25. After spraying, the electric water pump 7 is de-energized. The booster tube 24 can increase pressure, improve the sealing performance of the device, and reduce the amount of eye drops used per spray. Residual eye drops in the pipe can be pushed back into the storage tube 6 through the piston ring 27.
