[0032] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0033] Please refer to Figures 1 to 5As shown, an embodiment of the utility model provides an eye molding model, including a base 1, a T-shaped frame 2, a spherical shell 3 for simulating an eyeball, a water lens 4, a smoke generator 6, a syringe 9 and a corrective lens 13, the bottom of the transparent spherical shell 3 is fixedly connected with a support column 104, the support column 104 is fixedly connected to the top of the base 1, the smoke generator 6 is fixedly installed on the base 1, a mounting hole is opened on the spherical shell 3, the water lens 4 is fixedly installed in the mounting hole, a plurality of light source pens 5 with different luminous colors are detachably installed on the upper end of the T-shaped frame 2, the corrective lens 13 is arranged between the light source pen 5 and the water lens 4, wherein the corrective lens 13 includes a hyperopic lens and a myopic lens, the smoke outlet of the smoke generator 6 is connected to the inside of the spherical shell 3 through the smoke delivery pipe 7, the water outlet of the syringe 9 is connected to the water inlet of the water lens 4 through the water delivery pipe 11, and the inside of the spherical shell 3 is fixedly connected with a light screen 12 for simulating the retina.

[0034] By adopting the above technical solution, when simulating looking at a distant object, the light emitted by the multiple light source pens 5 is adjusted to be parallel to each other, and then the smoke generator 6 is turned on to deliver a certain amount of white smoke into the spherical shell 3. The light emitted by the light source pen 5 enters the spherical shell 3 after being refracted by the water lens 4, and is finally projected onto the light screen 12. The light entering the spherical shell 3 is diffusely reflected by the smoke particles in the spherical shell 3 to present a light path, so that students can more intuitively understand the changes of the light after entering the eyeball. At this time, in order to make the light emitted by the light source pen 5 clearly imaged on the light screen 12, the piston of the syringe 9 is pulled to slowly draw out the water in the water lens 4, gradually reduce the curvature of the water lens 4, and finally form a clear image on the light screen 12;

[0035] When simulating looking at a nearby object, the light emitted by the multiple light source pens 5 is adjusted to scattered light, and at this time, the piston of the syringe 9 is pushed to slowly add water into the water lens 4, gradually increasing the curvature of the water lens 4, and finally forming a clear image on the light screen 12;

[0036] When simulating myopia correction, the light emitted by the multiple light source pens 5 is adjusted to scattered light, and then the piston of the syringe 9 is pushed to slowly add water into the water lens 4 to increase the curvature of the water lens 4 so that the focus of the water lens 4 falls in front of the light screen 12. At this time, the myopia lens, that is, the concave mirror, is placed between the light source pen 5 and the water lens 4, so that the light emitted by the light source pen 5 can be clearly imaged on the light screen 12;

[0037] When simulating the correction of hyperopia, the light emitted by the multiple light source pens 5 is adjusted to be parallel to each other, and then the water in the water lens 4 is slowly pumped out, and the curvature of the water lens 4 is gradually reduced, so that the focus of the water lens 4 falls behind the light screen 12. At this time, the hyperopia lens, that is, the convex lens, is placed between the light source pen 5 and the water lens 4, so that the light emitted by the light source pen 5 can be clearly imaged on the light screen 12.

[0038] Specifically, an elastic clip 201 is rotatably mounted on the upper end of the T-shaped frame 2 . The elastic clip 201 is arranged in a C shape. The light source pen 5 is clamped and fixed on the elastic clip 201 . This arrangement facilitates the disassembly and assembly of the light source pen 5 .

[0039] Specifically, a smoke valve 8 is provided on the smoke conveying pipe 7 , and through the provided smoke valve 8 , after white smoke is flushed into the spherical shell 3 , the smoke valve 8 can be closed to prevent the smoke in the spherical shell 3 from flowing back into the smoke generator 6 .

[0040] Specifically, a support frame 101 is fixedly installed on the top of the base 1, and the syringe 9 is placed on the support frame 101. Limiting clamps 102 are arranged on both sides of one end of the support frame 101, and the pressing handles on both sides of the syringe 9 are inserted into the corresponding limiting clamps 102. Through this arrangement, it is convenient to push and pull the pull rod of the syringe 9 without holding by hand, and the operation is more convenient.

[0041] Specifically, a water valve 10 is provided on the water delivery pipe 11. Through the provided water valve 10, after adjusting the curvature of the water lens 4, the water valve 10 can be closed to prevent the curvature of the water lens 4 from changing.

[0042] Specifically, in order to improve the stability of the base 1 when it is placed, anti-skid rubber pads 103 are provided at the four corners of the bottom of the base 1.

[0043] It should be noted that the smoke generator 6 can be a micro smoke generator of model YWQ-701, and the spherical shell 3 can be made of a transparent acrylic material.

[0044] The above description shows and describes several preferred embodiments of the utility model, but as mentioned above, it should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the utility model concept described herein through the above teachings or the technology or knowledge of the relevant field.
