Description

Technical Field

[0001] This utility model relates to the field of eye protection instrument technology, and in particular to an optical eye protection instrument that facilitates beam shaping. Background Technology

[0002] An LED-based eye massager is an electronic eye care product that uses LED light source technology. It uses appropriate light waves to massage and care for the eyes. It is usually equipped with multiple eye care modes, such as massage, hot compress, and vibration, which can effectively relieve eye fatigue, improve blood circulation, and promote vision health. In addition, some advanced eye massagers also incorporate optical training programs to guide users to exercise their eye muscles through light source training, thereby improving eye health in multiple ways.

[0003] Traditional eye care devices can basically meet people's needs. They generally use red light for physiotherapy and care. The light spot at the light outlet of the eye mask of the eye care device is usually in the form of a whole piece. When the red light shines directly into the eyes, it will cover the pupil, causing the pupil to continuously contract and accommodative spasm, increasing the tension of the eye muscles, and thus causing discomfort symptoms such as dry eyes and eye irritation. In the long run, it may also damage the retinal cells, affecting the therapeutic and preventive effects of the eye care device. Therefore, this utility model proposes an optical eye care instrument with convenient beam shaping to solve the problems existing in the prior art. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes an optical eye protection instrument that facilitates beam shaping. This instrument adds a shaping lens at the spot formation point behind the second lens, and uses a central blocking circle to block the light spot into a ring-shaped spot, reducing direct exposure to the pupil, avoiding continuous pupil constriction and accommodative spasm, and ensuring the eye protection effect.

[0005] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: an optical eye protection instrument for convenient beam shaping, comprising an outer cylinder and an inner cylinder, wherein the outer cylinder is provided with two interconnected sets, an optical chamber is provided at one end of the outer cylinder, the inner cylinder is located inside the optical chamber, and one end of the inner cylinder is connected to the outer cylinder, an LED light source is provided at one end of the inner cylinder, and a first lens is provided inside the inner cylinder at one end of the LED light source, a second lens is provided inside the inner cylinder at one end of the first lens, and a shaping lens is provided inside the inner cylinder at one end of the second lens, with a blocking circle provided at the middle position of the shaping lens;

[0006] The shaping lens is mounted on a mounting bracket, which is inserted from the outer cylinder into the inner cylinder. A light-diffusing film is provided inside the inner cylinder at the position between the LED light source and the first lens.

[0007] A further improvement is that the mounting bracket has open sides and a slot at the bottom for inserting a shaping lens. There are multiple sets of shaping lenses, and the diameter of the obscuring circle of the multiple sets of shaping lenses is different.

[0008] A further improvement is that: an arc-shaped plate is provided above the mounting bracket, an insertion port is provided at one end of the outer cylinder, and an extension port is provided at one end of the inner cylinder. The mounting bracket passes through the insertion port and is inserted into the interior of the extension port, and the arc-shaped plate is supported above the insertion port.

[0009] A further improvement is that splicing rods are provided on both sides of the bottom of the arc-shaped plate, and splicing grooves are provided on the outer cylinder at both sides of the insertion port, with the splicing rods and splicing grooves being compatible.

[0010] A further improvement is that: one end of the outer cylinder is provided with an elastic rubber sleeve, and the elastic rubber sleeve is connected to the inner cylinder, and a protective lens is provided inside the elastic rubber sleeve.

[0011] A further improvement is that a drive chamber is provided at the end of the outer cylinder away from the optical chamber, and a circuit board is provided inside the drive chamber, which is electrically connected to the LED light source.

[0012] A further improvement is that a control button is provided at one end of each of the two outer cylinders, and the control button is electrically connected to the circuit board.
