Description

Technical Field

[0001] This utility model relates to the field of photoelectric switch cleaning technology, and in particular to a photoelectric switch cleaning mechanism for use in confined spaces. Background Technology

[0002] A photoelectric switch is an automatic detection device that uses optical signals to achieve control functions. It mainly consists of two parts: a transmitter and a receiver. The transmitter can emit light beams such as infrared light or laser light, while the receiver is responsible for detecting the presence or change of the light beam. When the object being measured approaches or blocks the light beam, the intensity of the light signal at the receiver changes, thereby triggering the switch to control the circuit's on / off state. The normal operation of a photoelectric switch depends on the stable transmission of the light signal between the transmitter and receiver. However, contaminants such as dust, oil, and moisture can easily adhere to the surface of its transmitter or receiver window, leading to a decrease in the intensity of the emitted light signal or the sensitivity of the receiver. Furthermore, a photoelectric switch that is not cleaned regularly may experience accelerated component aging due to the corrosion of contaminants, reducing its lifespan. Therefore, regularly cleaning the photoelectric switch and maintaining the transparency of its optical window is a necessary measure to ensure stable light signal transmission and maintain the detection accuracy and reliability of the equipment.

[0003] Currently, photoelectric switches are mostly cleaned by hand using lens cleaning paper or by using an air gun. However, many photoelectric switches are located in relatively narrow places, where people cannot reach their hands. At the same time, air guns cannot clean photoelectric switches located in narrow areas, and may even damage other parts near the photoelectric switch.

[0004] Therefore, there is an urgent need for a photoelectric switch cleaning mechanism for narrow spaces, which can solve the problem of the difficulty in cleaning photoelectric switches in narrow areas and achieve precise cleaning of photoelectric switches. Utility Model Content

[0015] As an alternative to the photoelectric switch cleaning mechanism for confined spaces, at least part of the cleaning component is inserted inside the mounting component, and the cleaning component outside the mounting component forms a fluffy wiping end.

[0016] As an alternative to the photoelectric switch cleaning mechanism for use in confined spaces, the cleaning element is made of microfiber filaments or filaments used to make the nozzle.

[0017] As an alternative to the photoelectric switch cleaning mechanism for confined spaces, the extension also includes a universal joint, one end of which is connected to the extension and the other end of which is connected to the mounting portion.

[0018] As an alternative to the photoelectric switch cleaning mechanism for narrow spaces, the photoelectric switch cleaning mechanism for narrow spaces also includes a handle, which is connected to the opposite end of the extension in the left-right direction.

[0019] As an alternative to the photoelectric switch cleaning mechanism for narrow spaces, the left half of the handle is approximately hemispherical, the right half of the handle is conical, and the right half narrows to the right.

[0031] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0032] This embodiment provides a photoelectric switch cleaning mechanism for confined spaces, such as... Figures 1-2 As shown, in this embodiment, the photoelectric switch cleaning mechanism for narrow spaces includes an extension 1, a mounting part 2, and a cleaning part. The extension 1 has a slender structure and includes an extension portion 11 and a mounting portion 12 connected to each other. The extension portion 11 extends in the left-right direction and is connected to an upwardly extending mounting portion 12 at one end. The mounting part 2 is connected to the mounting portion 12. The cleaning part is detachably connected to the mounting part 2. The cleaning part is used to clean the photoelectric switch. The above configuration allows the photoelectric switch cleaning mechanism for narrow spaces to reach photoelectric switch parts that are difficult to reach manually by virtue of the slender extension 1. The detachable connection design between the mounting part 2 and the cleaning part makes it easy to replace different types of cleaning parts to meet diverse cleaning needs. The photoelectric switch cleaning mechanism for narrow spaces replaces manual operation, which not only reduces the difficulty and danger of manual cleaning, but also avoids the problem of incomplete cleaning caused by insufficient manual cleaning, improves the cleaning effect and efficiency, reduces malfunctions caused by dust accumulation on the photoelectric switch, ensures stable operation of the equipment, and thus achieves efficient and precise cleaning.

[0033] Preferably, such as Figures 1-2As shown, in this embodiment, the extension 1 is a long, thin tubular structure. Its elongated shape allows it to penetrate deep into narrow spaces, precisely reaching the photoelectric switch area that is difficult to access by hand, thus achieving effective cleaning of the photoelectric switch within confined spaces. Simultaneously, the tubular structure reduces its weight, improves operational flexibility, and better meets the need for efficient and precise cleaning of photoelectric switches in narrow spaces. In other embodiments, the extension 1 can also be a long, thin sheet-like structure, as long as it can penetrate into narrow spaces to clean the photoelectric switch.

[0034] Preferably, the aspect ratio of the extension member 1 can be 45-70, allowing it to be more slender and extend into extremely narrow spaces with small diameters and long depths, precisely reaching the photoelectric switch mounting portion 12, while also enabling flexible operation within a limited space and avoiding dead angles. In this embodiment, the aspect ratio of the extension member 1 is 57.5. In other embodiments, the aspect ratio of the extension member 1 can also be 45, 47.5, 50, 52.5, 55, 60, 62.5, 65, 67.5, or 70, etc.

[0035] Optionally, the extension member 1 can be 350mm-450mm in length and 5mm-10mm in diameter. In this embodiment, the extension member 1 is 400mm long and 7mm in diameter. In other embodiments, the extension member 1 can also be 350mm, 375mm, 425mm, or 450mm in length, and 5mm, 6mm, 8mm, 9mm, or 10mm in diameter, as long as it can reach into a narrow area to clean the photoelectric switch.

[0036] Preferably, in this embodiment, the extension member 1 is a telescopic structure, which allows the length of the extension member 1 to be flexibly adjusted according to the specific depth of the narrow space. This enables the photoelectric switch cleaning mechanism for narrow spaces to reach the photoelectric switch part in narrow spaces of different depths, and can also be shortened when not in use for easy storage and carrying. This further enhances the adaptability of the cleaning mechanism to complex narrow spaces, expands its application range, and improves the convenience of operation, making the cleaning work more flexible and efficient.

[0037] Preferably, in this embodiment, the extension 11 includes a first tube, a second tube, and a linear electric cylinder. The fixed end of the linear electric cylinder is connected to the first tube, and the output end of the linear electric cylinder is connected to the second tube. The second tube is connected to the mounting part 12, allowing the extension 11 to precisely control the relative position between the second tube and the first tube through the telescopic movement of the linear electric cylinder, thereby achieving electric adjustment of the extension length. This makes the telescopic operation of the extension 11 more convenient and efficient. Furthermore, through precise electric control, it can more stably and accurately reach the photoelectric switch into narrow spaces. Compared to manual adjustment, this improves the accuracy and reliability of the adjustment, reduces the workload of the operator, and increases the efficiency of cleaning operations. In other embodiments, the linear electric cylinder can be replaced with a lead screw and nut structure or a linear pneumatic cylinder, as long as the telescopic function of the extension 11 can be achieved.

[0038] Specifically, such as Figures 1-2 As shown in this embodiment, the mounting member 2 is sleeved outside the mounting part 12, and the mounting member 2 is welded to the mounting part 12, which can achieve a stable connection between the mounting member 2 and the extension member 1, making the cleaning mechanism structurally stable and reliable when operating in narrow spaces. By welding the extension member 1 and the mounting member 2, it can be ensured that the mounting member 2 will not shift or fall off due to external forces during the cleaning process, thus ensuring the continuity and stability of the cleaning operation.

[0039] Optionally, the length of the mounting component 2 can be 25mm-35mm, the hole depth from top to bottom can be 15mm-20mm, the wall thickness can be 0.5mm-1.5mm, and the hole diameter can be 5mm-10mm. In this embodiment, the length of the mounting component 2 is 30mm, the hole depth from top to bottom is 17mm, the wall thickness is 1mm, and the hole diameter is 7mm. In other embodiments, the length of the mounting component 2 can also be 25mm, 27.5mm, 32.5mm, or 35mm, etc., the hole depth from top to bottom can also be 15mm, 16mm, 18mm, 19mm, or 20mm, etc., the wall thickness can also be 0.5mm, 0.75mm, 1.25mm, or 1.5mm, etc., and the hole diameter can also be 5mm, 6mm, 8mm, 9mm, or 10mm, etc.

[0040] Specifically, in this embodiment, at least a portion of the cleaning component is inserted inside the mounting component 2. The cleaning component outside the mounting component 2 forms a fluffy wiping end. The portion of the cleaning component inserted inside the mounting component 2 positions and fixes the cleaning component, so that the fluffy wiping end can wipe and clean the photoelectric switch in a stable state. The stable installation method can ensure that the wiping end maintains appropriate contact force and wiping shape during the cleaning process, making it easier to penetrate into the gaps or complex structures of the photoelectric switch, improving the targeting and effectiveness of cleaning. At the same time, the fluffy structure can increase the contact area with the cleaning part, enhance the dust removal and wiping effect, and the stable installation can reduce the possibility of the cleaning component falling off or shifting during the cleaning process, ensuring the smooth progress of the cleaning work.

[0041] Optionally, in this embodiment, the cleaning component is made of fiber filaments used to make the nozzle. The fiber filaments used to make the nozzle are soft and do not easily scratch the precision components of the photoelectric switch. They can penetrate into narrow spaces to contact stains and can also adsorb dust and impurities through the tiny gaps between the fiber filaments, improving the accuracy and thoroughness of cleaning. In addition, the material is wear-resistant and durable, can be reused, and reduces cleaning costs.

[0042] In other embodiments, the cleaning component can also be made of microfiber filaments, which, due to their extremely fine fiber diameter, can penetrate deep into the fine textures and crevices of the photoelectric switch surface to efficiently clean dirt, oil, and other stains. The advantages are that microfiber filaments have a large specific surface area and strong adsorption capacity, effectively absorbing dirt; their soft texture prevents scratching or abrasion of the delicate surface of the photoelectric switch; their dense fiber structure prevents lint shedding during cleaning, avoiding secondary contamination; and they possess good water absorption and quick-drying properties, meeting the diverse cleaning needs of photoelectric switches and ensuring the normal and stable operation of the equipment after cleaning. In other embodiments, the cleaning component can also be made of sponges or similar materials, as long as they can effectively clean the photoelectric switch.

[0043] Preferably, in this embodiment, the cleaning component is a cleaning tip, commonly found in tobacco workshops. One end of the tip is inserted into the mounting component 2, and the other end is torn open and fluffed to form a fluffy wiping end. The tip is soft and has fine fibers, and the fluffy wiping end has a large contact area, which can effectively absorb dust and clean deep into crevices without scratching the precision surface of the photoelectric switch. As a common material in tobacco workshops, it is easy to obtain and inexpensive, realizing resource reuse. New tips can also be replaced at any time according to usage, ensuring cleaning effect and efficiency and reducing equipment maintenance costs.

[0044] Preferably, in this embodiment, the aperture of the mounting member 2 is smaller than the diameter of the nozzle, enabling the nozzle to be securely fixed within the mounting member 2 via an interference fit, preventing it from loosening or falling off during the cleaning of the photoelectric switch. Because the aperture of the mounting member 2 is smaller than the diameter of the nozzle, the cleaning process of the photoelectric switch cleaning mechanism in confined spaces is more stable. This allows the fluffy wiping end to adhere to the surface of the photoelectric switch with appropriate force and angle, ensuring cleaning effectiveness. No additional fixing components or complex operations are required, simplifying the installation process, facilitating quick nozzle replacement, and improving cleaning efficiency. The stable connection formed by the interference fit enhances the safety and reliability of the cleaning mechanism. Optionally, in this embodiment, the aperture of the mounting member 2 is the nozzle diameter minus 0.6 mm. In other embodiments, the aperture of the mounting member 2 can also be the nozzle diameter minus 0.5 mm, 0.7 mm, or 0.8 mm, etc.

[0045] Preferably, in this embodiment, the extension 1 further includes a universal joint, one end of which is connected to the extension 11, and the other end of which is connected to the mounting portion 12. This allows the mounting portion 12 to rotate flexibly relative to the extension 11 within a certain range, enabling the cleaning component to change its angle with the universal joint. The universal joint design allows the cleaning mechanism to adjust its cleaning direction more flexibly in confined spaces, adapting to photoelectric switches at different positions and angles, improving the flexibility and accuracy of cleaning, ensuring comprehensive and efficient completion of cleaning tasks even in complex and confined environments, reducing cleaning blind spots, and enhancing the adaptability of the cleaning mechanism to diverse confined scenarios.

[0046] Preferably, such as Figures 1-2 As shown, in this embodiment, the photoelectric switch cleaning mechanism for narrow spaces also includes a handle 3. The handle 3 is connected to the other end of the extension 11 in the left-right direction, which can provide the operator with a stable grip point, making it easy to manipulate the extension 1 to go into the narrow space to adjust the cleaning position and angle. The grip of the handle 3 can improve the convenience, accuracy and stability of the cleaning operation, reduce the inconvenience or safety risks that the operator may face due to direct contact with the narrow space, and make the cleaning force and direction easier to control, further enhancing the cleaning effect and efficiency, and optimizing the overall user experience.

[0047] Optionally, in this embodiment, the extension 1 is threaded at the connection point with the handle 3. The threaded connection between the extension 1 and the handle 3 facilitates equipment storage and transportation, reduces space occupation, and allows for the replacement of handles 3 of different specifications according to the actual cleaning scenario, enhancing the adaptability and versatility of the photoelectric switch cleaning mechanism for use in confined spaces. Simultaneously, the threaded connection structure is robust and reliable, ensuring a tight fit between the handle 3 and the extension 1 during cleaning, guaranteeing stable cleaning operations. In other embodiments, the handle 3 and the extension 1 can also be magnetically connected or plugged in, as long as a stable grip for the photoelectric switch cleaning mechanism in confined spaces is achieved.

[0048] Preferably, such as Figures 1-2 As shown, in this embodiment, the left half of the handle 3 is approximately hemispherical, and the right half is conical, tapering to a thinner diameter towards the right. The handle 3 is formed by joining the left and right halves, with a smooth transition between them. This allows the handle 3 to conform to the physiological curvature of the palm, providing a comfortable and stable grip. The hemispherical left half fills the palm space, providing ample support, while the conical right half facilitates natural finger bending and gripping. The tapering design helps control the cleaning force and direction, and the smooth transition avoids pressure on the palm, reducing fatigue during prolonged use. This improves the comfort, stability, and accuracy of the cleaning operation, optimizing the cleaning experience. In other embodiments, the handle 3 can be circular or elongated, as long as it allows the user to stably grip the photoelectric switch cleaning mechanism used in confined spaces.

[0049] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
