The outer end of the lensometer body 1 is fixedly connected to the lower side of a lens table 3. The upper side of the lens table 3 is fixedly connected to the lower end of a cylinder 4. The output end of the cylinder 4 is fixedly connected to the inner wall of a slide plate 5. The inner side of the slide plate 5 is fixedly connected to the outer side of an eyeglass frame 6. The upper end of the eyeglass frame 6 is fixedly connected to the lower end of a lens holder 7. The outer end of the eyeglass frame 6 is fixedly connected to a temple frame 8. A temple groove 9 is formed on the lens table 3. A cleaning device 10 for keeping the spectacle lens clean and reducing measurement interference is arranged on the upper side of the lens table 3; Among them, the cleaning device 10 includes an L-shaped block 101, a toothed bed 102, a large rotating shaft 103, a gear 104, a fixed table 105, a cleaning frame 106, a sponge block 107, a connecting block 108, a return spring 109 and cleaning teeth 110. The outer side of the slide plate 5 is fixedly connected to the inner end of the L-shaped block 101. When the slide plate 5 moves, it drives the L-shaped block 101 to move. The upper end of the L-shaped block 101 is fixedly connected to the lower side of the toothed bed 102. When the L-shaped block 101 moves, it drives the toothed bed 102 to move. The outer wall of the lensometer body 1 is rotatably connected to the upper end of the large rotating shaft 103. The outer wall of the large rotating shaft 103 is fixedly connected to the inner wall of the gear 104, and the gear 104 meshes with the toothed bed 102. When the toothed bed 102 meshes with the gear 104, it drives the gear 104 to rotate. The upper side of the lens table 3 is fixedly connected to the lower side of the fixed table 105. The inner side of the fixed table 105 is slidably connected to the outer wall of the cleaning frame 106. When the gear 104 rotates, it drives the cleaning frame 106 to move towards the output end of the cylinder 4. The lower side of the cleaning frame 106 is fixedly connected to the upper side of the sponge block 107. When the cleaning frame 106 moves, it drives the sponge block 107 to move synchronously to wipe the dirt on the lens surface. The outer side of the cleaning frame 106 is fixedly connected to the inner side of the connecting block 108. When the cleaning frame 106 moves, it drives the connecting block 108 to move synchronously. The inner side of the connecting block 108 is fixedly connected to one end of the return spring 109. The other end of the return spring 109 is fixedly connected to the cleaning teeth 110, and the upper end of the cleaning teeth 110 is slidably connected to the lower end of the connecting block 108. When the connecting block 108 moves, through the cooperation of the return spring 109 and the cleaning teeth 110, the dirt at the gap between the lens and the lens frame is cleared out.

[0021] In the present invention, by providing a cleaning device 10 and starting the cylinder 4, the slide plate 5 is driven by the cylinder 4 at this time, which drives the L-shaped block 101, and cooperates with the toothed bed 102 and the large rotating shaft 103 to make the gear 104 start to rotate. The cleaning frame 106 drives the sponge block 107 to move in the opposite direction of the output direction of the cylinder 4 to wipe the dirt on the surface of the lens, solving the problem that the dirt on the mirror surface reduces the detection accuracy, thereby improving the detection accuracy; When the cylinder 4 drives the cleaning frame 106 to move, the connecting block 108 moves synchronously, and through the cooperation of the return spring 109 and the cleaning teeth 110, the cleaning teeth 110 clear the dirt in the gap between the lens and the frame that cannot be wiped by the sponge block 107 in advance, and then the sponge block 107 wipes it off, solving the problem that the sponge block 107 cannot wipe off the dirt in the gap between the lens and the frame, thereby improving the cleaning effect of the device.

[0022] When this embodiment is in operation: Place the glasses in, with the nose pads of the glasses positioned at the center of the glasses frame 6, place the lenses on the lens holder 7, and at the same time, the temple arms are restricted by the temple holders 8. Then start the cylinder 4. When the cylinder 4 starts, it drives the sliding plate 5 to slide. When the sliding plate 5 slides, it drives the entire glasses frame 6 to move, thereby adjusting the position of the glasses. When the sliding plate 5 slides forward, it drives the L-block 101 to slide forward. When the L-block 101 slides forward, it drives the tooth bed 102 to move forward. When the tooth bed 102 moves forward, it meshes with the gear 104, causing the gear 104 to rotate around the large rotating shaft 103. When the gear 104 rotates, it meshes with the cleaning frame 106, causing the cleaning frame 106 to move in the opposite direction of the output direction of the cylinder 4. When the cleaning frame 106 moves, it drives the sponge block 107 to move in the opposite direction of the output direction of the cylinder 4 to wipe the surface of the lens. Conversely, when the cylinder 4 starts, it pulls the sliding plate 5 to slide. When the sliding plate 5 slides backward, it drives the L-block 101 to slide backward. When the L-block 101 slides backward, it drives the tooth bed 102 to move backward. When the tooth bed 102 moves backward, it meshes with the gear 104, causing the gear 104 to rotate around the large rotating shaft 103. When the gear 104 rotates, it meshes with the cleaning frame 106, causing the cleaning frame 106 to move in the opposite direction of the output direction of the cylinder 4. When the cleaning frame 106 moves, it drives the sponge block 107 to move in the opposite direction of the output direction of the cylinder 4 to wipe the surface of the lens, facilitating the detection by the detection component 2. When the cleaning frame 106 moves forward, it drives the connecting block 108 to move forward. When the connecting block 108 moves forward, it drives the cleaning teeth 110 to move forward. When the cleaning teeth 110 move forward, they scrape the dirt in the gap between the lens and the frame. When the cleaning teeth 110 continue to move forward to the curved part of the frame, the cleaning teeth 110 follow the curvature of the frame and squeeze the return spring 109 to clear the dirt at the curved frame part. Conversely, when the cleaning frame 106 moves backward, it drives the connecting block 108 to move backward. When the connecting block 108 moves backward, it drives the cleaning teeth 110 to move backward. When the cleaning teeth 110 move backward, they scrape out the dirt in the gap between the lens and the frame. When the cleaning teeth 110 continue to move backward to the curved part of the frame, the cleaning teeth 110 follow the curvature of the frame and squeeze the return spring 109 to remove the dirt at the curved frame part, facilitating the subsequent wiping of the dirt by the sponge block 107.

[0023] Please refer to Figures 1-6, on the basis of the above embodiments, in another embodiment of the present invention, a blowing device 11 for blowing away small particles on the lens to prevent scratching the lens during cleaning is provided on the upper side of the lens table 3. The blowing device 11 includes a blowing block 111, an air chamber 112, a pressure nozzle 113, a pressing piece 114 and a V-shaped block 115; the upper side of the fixed table 105 is fixedly connected to the lower side of the blowing block 111. An air chamber 112 is opened inside the blowing block 111. The output end of the air chamber 112 is fixedly connected to the outer end of the pressure nozzle 113. The inner wall of the air chamber 112 is slidably connected to the outer wall of the pressing piece 114. When the pressing piece 114 moves, it drives the gas in the air chamber 112 to be ejected through the pressure nozzle 113 to blow away the small particles on the lens. The inner side of the pressing piece 114 is fixedly connected to the outer side of the V-shaped block 115. The lower side of the V-shaped block 115 is fixedly connected to the upper side of the cleaning frame 106. When the cleaning frame 106 moves, it drives the V-shaped block 115 to move, and the V-shaped block 115 drives the pressing piece 114 to move synchronously.

[0024] In the present invention, by setting the blowing device 11, when the cleaning frame 106 moves, the cleaning frame 106 drives the V-shaped block 115 to move, the V-shaped block 115 drives the pressing piece 114 to slide, the pressing piece 114 pushes the gas in the air chamber 112, and the gas is pressurized and ejected through the pressure nozzle 113 to blow away the small particles on the lens before the sponge block 107 wipes the lens, solving the problem that the sponge block 107 drives small particles to scratch the lens during wiping, and greatly reducing the loss probability of the lens.

[0025] A protection device 12 for covering the detection component 2 when not in use is provided on the upper side of the lens table 3. The protection device 12 includes an L-shaped rod 121, a protection frame 122, a small rotating shaft 123, a flip door 124, a torsion spring 125 and a pressing block 126; the inner side of the V-shaped block 115 is fixedly connected to the outer end of the L-shaped rod 121. When the V-shaped block 115 moves, it drives the L-shaped rod 121 to move synchronously. The inner side of the L-shaped rod 121 is fixedly connected to the outer wall of the protection frame 122. When the L-shaped rod 121 moves, it drives the protection frame 122 to move synchronously to cover and protect the detection component 2. The inner wall of the protection frame 122 is rotatably connected to the outer wall of the small rotating shaft 123. The outer wall of the small rotating shaft 123 is fixedly connected to the inner wall of the flip door 124. The inner wall of the protection frame 122 is fixedly connected to one end of the torsion spring 125, and the other end of the torsion spring 125 is fixedly connected to the outer wall of the flip door 124. The lower side of the lensometer body 1 is fixedly connected to the upper end of the pressing block 126. When the small rotating shaft 123 moves, it drives the flip door 124 to move synchronously. Through the cooperation of the pressing block 126 and the small rotating shaft 123, the flip door 124 will not touch the detection component 2 when flipping and moving.

[0026] In the present invention, when the V-block 115 moves, the protection device 12 is provided such that the V-block 115 drives the L-rod 121 to move, the L-rod 121 drives the protection frame 122 to slide on the lensometer body 1, and drives the flip door 124 to move synchronously. Through the cooperation of the extrusion block 126 and the small rotating shaft 123, the flip door 124 will not touch the detection component 2 during the flipping movement. During this process, the protection frame 122 cooperates to mask the inoperative detection component 2, solving the problem that the detection component 2 may be damaged by accidental touch when not in use, and improving the service life of the device.

[0027] During the operation of this embodiment: when the cleaning frame 106 moves forward, it drives the V-block 115 to move forward. When the V-block 115 moves forward, it drives the extrusion piece 114 to slide forward on the inner wall of the air chamber 112. When the extrusion piece 114 slides forward on the inner wall of the air chamber 112, the gas in the blowing block 111 is squeezed through the extrusion piece 114, so that the gas is pressurized and ejected through the pressure nozzle 113; conversely, when the cleaning frame 106 moves backward, it drives the V-block 115 to move backward. When the V-block 115 moves backward, it drives the extrusion piece 114 to slide backward on the inner wall of the air chamber 112. When the extrusion piece 114 slides backward on the inner wall of the air chamber 112, the gas in the blowing block 111 is squeezed through the extrusion piece 114, so that the gas is pressurized and ejected through the pressure nozzle 113, blowing away the small particles on the spectacle lens and preventing the sponge block 107 from driving the small particles to scratch the lens when wiping.

[0028] When the V-block 115 moves forward, it drives the L-rod 121 forward. When the L-rod 121 moves forward, it drives the protection frame 122 forward. When the protection frame 122 moves forward, it drives the small rotating shaft 123 to move forward synchronously. When the small rotating shaft 123 moves forward, it drives the flip door 124 forward. When the flip door 124 moves forward, the flip door 124 collides with the extrusion block 126. When the flip door 124 collides with the extrusion block 126, the flip door 124 flips, and the extrusion block 126 supports the flipped flip door 124 to prevent the flip door 124 from colliding with the detection component 2 during the flipping movement. After that, under the action of the torsion spring 125, the flip door 124 resets; conversely, when the V-block 115 moves backward, it drives the L-rod 121 backward. When the L-rod 121 moves backward, it drives the protection frame 122 backward. When the protection frame 122 moves backward, it drives the small rotating shaft 123 to move backward synchronously. When the small rotating shaft 123 moves backward, it drives the flip door 124 backward. When the flip door 124 moves backward, the flip door 124 collides with the extrusion block 126. When the flip door 124 collides with the extrusion block 126, the flip door 124 flips, and the protection frame 122 masks the detection component 2 to protect the detection component 2.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
