This not only affects the accuracy of test data but can also lead to performance degradation or even failure. Therefore, regular cleaning of the detection device is crucial to ensuring its accuracy and reliability. However, traditional cleaning methods often rely on manual labor, which is not only time-consuming and labor-intensive, but also suffers from incomplete cleaning. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example 1

[0025] like Figures 1-4As shown, the utility model provides a technical solution: a dust concentration detection device that is easy to clean, comprising: a cleaning mechanism 1, a limiting mechanism 2 is provided on one side of the cleaning mechanism 1, the cleaning mechanism 1 comprises a detector body 11, a connecting pipe 13 is provided on one side of the detector body 11, one side of the detector body 11 is fixedly connected with one end of the connecting pipe 13, the inner wall of the connecting pipe 13 is provided with a guide rail 14, the inner wall of the connecting pipe 13 is fixedly connected to one end of the guide rail 14, the other end of the guide rail 14 is provided with a slider 15, the other end of the guide rail 14 is slidably connected to the inner wall of the slider 15, the other end of the slider 15 is provided with an outer ring 16, the other end of the slider 15 is fixedly connected to one side of the outer ring 16, the inner wall of the outer ring 16 is provided with a scraper 17, the inner wall of the outer ring 16 is fitted with the outer side of the scraper 17, the inner wall of the outer ring 16 is provided with a spring 19, the inner wall of the outer ring 16 is fixedly connected to one end of the spring 19, the spring 1 The other end of 9 is provided with a column 18, the other end of spring 19 is fixedly connected to the inner wall of column 18, one end of column 18 is connected through the inner wall of outer ring 16, one end of column 18 is fixedly connected to one side of scraper 17, the other end of column 18 is provided with a tapered column 110, the other end of column 18 is in sliding contact with one side of tapered column 110, the inner wall of tapered column 110 is provided with a screw rod 111, the inner wall of tapered column 110 is threadedly connected to the outer side of screw rod 111, one end of screw rod 111 is provided with a motor 112, one end of screw rod 111 is fixedly connected to the output end of motor 112, one end of motor 112 is fixedly connected to one side of the inner wall of connecting pipe 13, the outer side of connecting pipe 13 contacts the inner side of intake ring 12, one side of outer ring 16 is provided with spring 2 113, one side of outer ring 16 is fixedly connected to one end of spring 2 113, and the other end of spring 2 113 is fixedly connected to one side of detector body 11.

[0026] In this embodiment, when this type of dust concentration detection device that is easy to clean is in use, after the detector body 11 has completed the dust detection, there will be adsorbed dust on the inner wall of its connecting tube 13. Therefore, by starting the motor 112, the screw rod 111 drives the cone column 110 to move during the rotation, and the cone column 110 will gradually exert an external force on the column 18 during the movement, causing it to move upward in the outer ring 16. Due to the upward movement of the scraper 17 of the column 18, it will fit with the inner wall of the connecting tube 13. At this time, the screw rod 111 continues to rotate, and the rear end of the cone column 110 will press against the column 18, thereby driving the outer ring 16 to move in the connecting tube 13, and the scraper 17 will scrape out the dust during the movement. Removing dust can maintain the accuracy and reliability of the dust concentration detection device. The accumulation of dust may affect the detection results or cause the performance of the equipment to decline. Therefore, regular cleaning can ensure the normal operation of the equipment and provide accurate detection data.

[0027] Secondly, when the cone column 110 returns to its original position, in order to ensure that the outer ring 16 can automatically reset, a spring 2 113 is designed on one side of the outer ring 16. When the outer ring 16 moves, the spring 2 113 is continuously stretched. After the external force of the cone column 110 disappears, the spring 2 113 uses its own retractability to reset the outer ring 16. The design of the spring 2 113 makes the equipment operation easier and more reliable. The operator does not need to manually intervene in the position of the outer ring 16, but relies on the mechanical design and the power of the spring to realize the automatic reset process, saving operation time and work complexity.

[0028] Example 2

[0029] like Figures 1-4 As shown, the limiting mechanism 2 includes a plug plate 21, and a limiting rod 22 is provided on the inner wall of one end of the plug plate 21. The inner wall of one end of the plug plate 21 is vertically clamped with one end of the limiting rod 22. One end of the limiting rod 22 is connected through the inner wall of one end of the top side of the connecting pipe 13. The inner wall of one end of the top side of the connecting pipe 13 is connected through the outer side of one end of the plug plate 21. The other end of the plug plate 21 is provided with an intake ring 12, and the other end of the plug plate 21 is fixedly connected to one side of the intake ring 12.

[0030] In this embodiment, the fixing of the inserting plate 21 is released by removing the limiting rod 22 from the inserting plate 21. Since the fixing of the inserting plate 21 is released, the air intake ring 12 can be removed from the connecting pipe 13. The air intake ring 12 is located upstream of the connecting pipe 13 and is the first entrance for dust to enter the detection device. As time goes by, a large amount of dust and impurities may accumulate on the surface of the air intake ring 12. Regular cleaning of the air intake ring 12 can effectively remove the accumulated dust. The accumulation of dust may cause poor intake flow and even affect the interior of the precision detection instrument. Regular cleaning can ensure that the air intake ring 12 is unobstructed, ensuring that dust can smoothly enter the detection device for accurate measurement.

[0031] Working principle:

[0032] like Figures 1-4 As shown, the motor 112 is started so that the screw rod 111 drives the cone column 110 to move during the rotation process. The cone column 110 will gradually exert an external force on the column 18 during the movement, causing it to move upward in the outer ring 16. As the column 18 moves upward, the scraper 17 will fit the inner wall of the connecting tube 13. At this time, the screw rod 111 continues to rotate, and the rear end of the cone column 110 will press against the column 18, thereby driving the outer ring 16 to move in the connecting tube 13. The scraper 17 will scrape out the dust during the movement. Removing the dust can maintain the accuracy and reliability of the dust concentration detection device.

[0033] Remove the limiting rod 22 from the insert plate 21 to release the insert plate 21. With the insert plate 21 now released, the intake ring 12 can be removed from the connecting pipe 13. The intake ring 12, located upstream of the connecting pipe 13, is the first entry point for dust entering the detection device. Over time, a large amount of dust and impurities may accumulate on the surface of the intake ring 12. Regular cleaning of the intake ring 12 effectively removes this accumulated dust.

[0034] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
