[0001] The present invention relates to the technical field of scanners, and in particular to an optical scanner with a mirror protection structure. Background Art
[0002] The scanner light source shines light on the drawing to be input, generating reflected light or transmitted light representing the image features. The optical system collects these lights and focuses them on the photosensitive device, which converts the light signals into electrical signals. The circuit part then performs A / D conversion and processing on these signals to generate corresponding digital signals for transmission to the computer. When the mechanical transmission mechanism drives the scanning head equipped with the optical system and CCD to move relative to the drawing under the control of the control circuit, the entire drawing is scanned and a complete image is input into the computer.
[0003] According to a publicly disclosed scanner with an end protection structure (announcement number: CN219761099U), the above application includes a scanner base and a scanning end mechanism, a hand-held rod is provided at the top of the scanner base, and a scanning end frame is installed at the top of the hand-held rod, the scanning end mechanism is installed at the front end of the scanning end frame, and a scanning end plug-in mechanism is installed at the rear end of the scanning end frame, and the scanning end plug-in mechanism includes a through column and a scanning end plug-in frame.
[0004] However, the above-mentioned scanner lacks a device to cover the scanning end after use. The end of the optical scanner sometimes carries static electricity. The unprotected end will absorb more dust or particles, affecting the transmission quality of light, causing blurred and distorted images, and affecting the clarity and accuracy of the scan. In view of this, we propose an optical scanner with a mirror protection structure. Summary of the invention

[0015] Preferably, the magnetic part is magnetically connected to the outer wall of the scanner body, and the baffle is located at the bottom of the transverse groove. After the magnetic part is adsorbed to the outer wall of the scanner body, the baffle blocks the transverse groove to prevent dust and other impurities from re-entering the gap between the lens and the shell through the transverse groove, thereby preventing secondary contamination of the lens.

[0019] Compared with the prior art, the present invention provides an optical scanner with a mirror protection structure, which has the following beneficial effects:
[0020] 1. The optical scanner with a mirror protection structure has a protective component, and the housing is sleeved on the lens of the scanner body. The housing protects the lens. The housing acts as a physical barrier to prevent the lens from being hit, scratched or squeezed by hard objects during storage or transportation, thereby protecting the optical components from damage. When the push rod is pushed, the high-speed gas blown out by the air blow blows the dust and gravel on the surface of the lens toward the horizontal groove, and is discharged through the horizontal groove to the gap between the housing and the scanner body lens. Compared with the direct contact cleaning method, the lens surface can be cleaned by the air flow, which can avoid scratching the lens surface. The high-speed air flow can blow away the dust, gravel and other tiny particles on the lens surface, and at the same time does not introduce new Dust, first blow air to the lens to remove most of the dust and particles, and then sweep away the remaining dust by sweeping. The airflow will blow away large particles and floating dust first to avoid direct contact between the cleaning brush and particles, prevent particles from scratching the lens under the push of the cleaning brush, and protect the lens surface from being scratched. This step-by-step cleaning can clean the lens surface more thoroughly and improve the cleaning effect. At the same time, airflow dust blowing can reduce static electricity on the lens surface, so that when the cleaning brush is sweeping away residual dust, the dust will not re-attach to the lens due to static electricity. When blowing dust, the cleaning brush does not contact the lens, keeping the airflow directly acting on the lens surface and keeping the airflow direction consistent, thereby enhancing the effect of blowing dust.
[0021] 2. The optical scanner with a mirror protection structure has a sealing component set up. When the movable plate moves toward the lens, the movable plate pushes the shielding plate to shield the transverse groove. After the magnetic part is adsorbed to the outer wall of the scanner body, the spring pushes the movable plate to reset without causing the shielding plate to reset. The shielding plate shields the transverse groove. After cleaning, the shielding plate covers the transverse groove to prevent the blown dust and impurities from flowing back into the gap between the lens and the shell, thereby blocking the path of secondary pollution from the source and ensuring that the lens is continuously clean after cleaning. After the outlet of the transverse groove is closed, the possibility of floating dust in the air entering the gap is reduced, so that the cleaned lens is not easily contaminated again.
[0022] 3. The optical scanner with a mirror protection structure has a storage component. After the lens on the scanner body is cleaned, the push rod is taken out and then inserted into the push rod, thereby reducing the volume occupied by the protection component and facilitating the storage or transportation of the scanner. The storage hole provides a dedicated fixed position to ensure that the push rod can be safely stored when not in use, avoiding loss or damage due to improper placement.

DETAILED DESCRIPTION
[0031] like Figure 1-Figure 7As shown, the present invention provides a technical solution: an optical scanner with a mirror protection structure, comprising a scanner body 1, a transverse groove 2 is provided on the bottom end face of the scanner body 1, the outer wall of the scanner body 1 is sleeved with a shell 3, the inner wall of the shell 3 is fixedly connected with a partition 4, the side wall of the partition 4 is fixedly connected with an inner interlayer 5, the inner interlayer 5 is sleeved with the inner wall of the scanner body 1, the sleeve connection of the scanner body 1 is achieved through the shell 3 and the inner interlayer 5, the stability of the installation of the shell 3 is improved, the inner wall of the shell 3 is provided with a protective component 6, the protective component 6 includes an air blow 601, an air outlet nozzle 602, a through hole 603, a movable plate 604, a spring 605, a push rod 606, a threaded rod 607, a limit frame 608, a sleeve ring 609, an elastic ring 610, a threaded sleeve 611, a cleaning brush 612, and a transmission belt 613.
[0032] In one embodiment of the present invention, an air blower 601 is arranged on one side of a partition 4, an air outlet nozzle 602 is provided on the side of the air blower 601 close to the partition 4, a through hole 603 is provided on the end face of the partition 4, the air outlet nozzle 602 is located in the through hole 603, and a movable plate 604 squeezes the air blower 601 to blow the air in the air blower 601 out through the air outlet nozzle 602. The high-speed gas blows the dust and gravel on the surface of the lens toward the transverse groove 2, and is discharged from the gap between the shell 3 and the lens of the scanner body 1 through the transverse groove 2.
[0033] The movable plate 604 is arranged on the side of the air blow 601 away from the partition 4, and a push rod 606 is sleeved on the side of the movable plate 604 away from the air blow 601. The side wall of the movable plate 604 close to the air blow 601 is fixedly connected with a spring 605 and a threaded rod 607. The number of springs 605 is arranged in several groups, and one end of the several groups of springs 605 is fixedly connected to the movable plate 604, and one end of the spring 605 is fixedly connected to the end surface of the partition 4. After the push rod 606 is pressed down, the spring 605 elastically pushes the movable plate 604 and the push rod 606 to reset. A circular hole is arranged in the middle of the air blow 601, and the threaded rod 607 passes through the circular hole. The threaded rod 607 does not contact the outer surface of the air blow 601, and the longitudinal movement of the threaded rod 607 will not scratch the air blow 601, thereby causing damage to the air blow 601.
[0034] The limiting frame 608 is fixedly connected to the side of the partition 4 away from the air blow 601. The inner wall of the limiting frame 608 is sleeved with a sleeve ring 609 and an elastic ring 610. The inner wall of the sleeve ring 609 is sleeved with a threaded sleeve 611. The end of the threaded sleeve 611 away from the threaded rod 607 is fixedly connected with a cleaning brush 612. The threaded rod 607 is sleeved with the threaded sleeve 611. The number of threaded sleeves 611 is arranged in several groups. Several groups of threaded sleeves 611 are connected through the sleeved transmission belt 613 to push the push rod 606. The threaded rod 607 pushes the threaded sleeve 611 to rotate the threaded sleeve 611, which further drives the cleaning brush 612 to rotate. The rotation of the cleaning brush 612 sweeps away the dust remaining on the lens.
[0035] After using the optical scanner, the shell 3 is put on the lens of the scanner body 1. The shell 3 protects the lens. As a physical barrier, the shell 3 can prevent the lens from being hit, scratched or squeezed by hard objects during storage or transportation, thereby protecting the optical components from damage and extending the service life of the scanner. At the same time, it isolates dust in the air and prevents these pollutants from directly contacting the lens surface, keeping the lens clean and preventing dirt from affecting the scanning quality.
[0036] Push the push rod 606 so that the push rod 606 pushes the movable plate 604 to move toward the scanner body 1. The lateral movement of the movable plate 604 squeezes the air blow 601, and the air in the air blow 601 is blown out through the air outlet nozzle 602. The blown high-speed gas blows the dust and gravel on the lens surface toward the transverse groove 2, and is discharged through the transverse groove 2 to the gap between the shell 3 and the scanner body 1 lens. Compared with the direct contact cleaning method, using airflow to clean the lens surface can avoid scratching the lens surface. The high-speed airflow can blow away tiny particles such as dust and gravel on the lens surface without introducing new dust, thereby protecting the optical performance of the lens and preventing these foreign objects from causing wear to the lens, ensuring that the lens is clear and free of dirt, and maintaining the scanning quality.
[0037] The movable plate 604 moves laterally, pushing the threaded rod 607 to move in the direction of the threaded sleeve 611, and the threaded rod 607 drives the threaded sleeve 611 to move toward the lens. At this time, the elastic ring 610 undergoes elastic deformation. When the elastic ring 610 is squeezed to the limit, the lateral movement of the threaded rod 607 drives the threaded sleeve 611 to rotate, and further drives the cleaning brush 612 to rotate. The rotation of the cleaning brush 612 sweeps away the dust remaining on the lens. First, blow air to the lens to remove most of the dust and particles, and then sweep away the remaining dust by sweeping. The airflow first blows away large particles and floating dust to avoid direct contact between the cleaning brush 612 and the particles, preventing the particles from scratching the lens under the push of the cleaning brush 612, and protecting the lens surface from being scratched. This step-by-step cleaning can clean the lens surface more thoroughly and improve the cleaning effect. At the same time, the airflow dust blowing can reduce the static electricity on the lens surface, so that when the cleaning brush 612 sweeps away the residual dust, the dust will not re-attach to the lens due to static electricity.
[0038] When blowing dust, the cleaning brush 612 does not contact the lens, so that the airflow directly acts on the lens surface and the airflow direction is kept consistent, thereby enhancing the dust blowing effect and ensuring that most of the dust is smoothly blown to the horizontal groove 2 for discharge.
[0039] In addition, a closing component 7 is provided on the side wall of the movable plate 604, and the closing component 7 includes an elastic member 701, a shielding plate 702, and a magnetic member 703. The elastic member 701 is fixedly connected to the side wall of the closing component 7, and the end of the elastic member 701 away from the movable plate 604 is fixedly connected to the shielding plate 702, and the end of the shielding plate 702 away from the elastic member 701 is fixedly connected to the magnetic member 703. The magnetic member 703 is magnetically connected to the outer wall of the scanner body 1, and the shielding plate 702 is located at the bottom of the transverse groove 2. When the movable plate 604 moves toward the lens, the movable plate 604 pushes the shielding plate 702 to shield the transverse groove 2. The magnetic member 703 is magnetically connected to the outer wall of the scanner body 1. After the outer wall of body 1 is adsorbed, the reset of movable plate 604 pushed by spring 605 will not lead to the reset of shielding plate 702. Shielding plate 702 blocks transverse groove 2. Shielding plate 702 covers transverse groove 2 after cleaning is completed to prevent blown-out dust and impurities from flowing back into the gap between lens and shell 3, thereby blocking the path of secondary pollution from the source and ensuring the continuous cleaning state of lens after cleaning. After the outlet of transverse groove 2 is closed, the possibility of floating dust in the air entering the gap is reduced, making it difficult for the cleaned lens to be contaminated again. This means that the equipment can remain clean for a longer period of time, extending the effective period of each cleaning and reducing the need for frequent cleaning.
[0040] Furthermore, the outer wall of the housing 3 is provided with a storage assembly 8, which includes a fixing block 801, a storage hole 802, and a notch 803. The fixing block 801 is fixedly connected to the outer wall of the housing 3, and the end surface of the fixing block 801 is provided with a storage hole 802, and the end surface of the fixing block 801 is provided with a notch 803. After the lens on the scanner body 1 is cleaned, the push rod 606 is taken out, and then the push rod 606 is inserted into the push rod 606, so as to reduce the volume occupied by the protective assembly 6, and facilitate the scanning. The storage hole 802 provides a dedicated fixed position to ensure that the push rod 606 can be safely stored when not in use, avoiding loss or damage due to improper placement. The storage hole 802 is connected to the push rod 606, and the notch 803 is located on the outside of the storage hole 802. The notch 803 is set to facilitate the operator to take out the push rod 606, and then insert the push rod 606 into the end face of the movable plate 604, and then push the movable plate 604 to clean the lens on the scanner body 1.
[0041] In the present invention, after using the optical scanner, the housing 3 is put on the lens of the scanner body 1. The housing 3 acts as a physical barrier to prevent the lens from being hit, scratched or squeezed by hard objects during storage or transportation. The push rod 606 is pushed, and the push rod 606 pushes the movable plate 604 to move toward the scanner body 1. The lateral movement of the movable plate 604 squeezes the air blow 601. The high-speed gas blown by the air blow 601 blows the dust and gravel on the surface of the lens toward the transverse groove 2. The dust and gravel are discharged from the gap between the housing 3 and the lens of the scanner body 1 through the transverse groove 2. The movable plate 604 moves laterally to push the threaded rod 607 toward the threaded sleeve 61 1, the movement of the threaded rod 607 drives the threaded sleeve 611 to rotate, and the rotation of the cleaning brush 612 sweeps away the dust remaining on the lens to achieve secondary cleaning of the lens. When the movable plate 604 moves toward the lens, the movable plate 604 pushes the shielding plate 702 to shield the transverse groove 2, and the magnetic member 703 fixes the position of the shielding plate 702 to prevent the blown dust and impurities from flowing back into the gap between the lens and the housing 3. After the lens on the scanner body 1 is cleaned, take out the push rod 606, and then insert the push rod 606 into the push rod 606 to prevent the push rod 606 from being lost or damaged due to improper placement.
[0042] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
