Description

Technical Field

[0001] This utility model relates to the field of analyzer technology, and in particular to an anti-clogging oxygen analyzer. Background Technology

[0002] An analyzer is an instrument used for qualitative or quantitative analysis of the composition, structure, and properties of substances. It uses various physical, chemical, or biological principles and techniques to convert the relevant information of the substance being tested into measurable signals. After processing and analysis, specific information about the substance being tested is obtained, such as the types and contents of its components, structural characteristics, and physicochemical properties.

[0003] However, in existing technologies, excessive dust accumulation on the dust filters of some devices can cause the mesh to shrink or even become clogged, resulting in a reduction in the gas flow rate into the analyzer. This can lead to inaccurate measurement results because the amount of oxygen entering the analyzer is insufficient, failing to accurately reflect the oxygen concentration in the actual environment. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing an anti-clogging oxygen analyzer. This ensures that gas enters the analyzer in a normal state, allowing the sensor to accurately detect oxygen concentration, guaranteeing the accuracy of measurement results, reducing the workload of components such as the air pump, decreasing wear, and extending their service life. It also avoids signal transmission interference or interruption caused by mutual compression, stretching, or poor contact of wires, ensuring the accuracy and stability of oxygen analyzer measurement data, and enabling the instrument to accurately detect and transmit oxygen concentration signals.

[0005] To achieve the above objectives, an anti-clogging oxygen analyzer is provided, comprising an analyzer, wherein multiple fixed blocks are fixedly connected inside the analyzer, a first limiting groove is formed inside the fixed block, a second limiting groove is formed inside the fixed block, a sliding block is slidably connected inside the fixed block, two springs are fixedly connected to one end of the sliding block, a telescopic rod is fixedly connected to one end of the sliding block, and a collar is fixedly connected to the outside of the sliding block.

[0006] According to the aforementioned anti-clogging oxygen analyzer, one end of the spring is fixedly connected to the interior of the fixed block, and one end of the telescopic rod is fixedly connected to the interior of the fixed block.

[0007] According to the aforementioned anti-clogging oxygen analyzer, a sponge pad is fixedly connected inside the analyzer, and multiple wires are arranged inside the sponge pad.

[0008] According to the aforementioned anti-clogging oxygen analyzer, the analyzer has an internal display screen and a housing fixedly connected to the rear side of the analyzer.

[0009] According to the aforementioned anti-clogging oxygen analyzer, a dustproof mesh is fixedly connected inside the housing, and multiple ventilation openings are provided inside the housing.

[0010] According to the aforementioned anti-clogging oxygen analyzer, a drive rod is rotatably connected to the outside of the dustproof net, and a motor is fixedly connected to the output end of the drive rod.

[0011] According to the aforementioned anti-clogging oxygen analyzer, a first gear is fixedly connected to the outside of the drive rod, and two second gears are externally meshed with the first gear.

[0012] According to the aforementioned anti-clogging oxygen analyzer, a rotating rod is fixedly connected inside the second gear, and multiple scrapers are fixedly connected outside the rotating rod.

[0013] According to the aforementioned anti-clogging oxygen analyzer, the analyzer is externally fixedly connected to multiple buffer pads, the buffer pads are externally fixedly connected to protective plates, the buffer pads are internally fixedly connected to telescopic rings, and the telescopic rings are externally slidably connected to limiting blocks.

[0014] Beneficial effects:

[0015] 1. Driven by a motor and a drive rod, the external first gear rotates, which in turn drives the second gears at both ends to rotate. The rotation of the second gears drives the internal rotating rod to rotate, causing the scraper on the outside of the rotating rod to rotate and clean the dust adhering to the surface of the dustproof net. This ensures that the gas can enter the analyzer in a normal state, allowing the sensor to accurately detect the oxygen concentration, ensuring the accuracy of the measurement results, reducing the workload of components such as the air pump, reducing wear, and extending their service life.

[0016] 2. Install the wire in the groove inside the sponge pad on the back of the analyzer, and press the collar to move the sliding block outside the collar in the first limiting groove inside the fixed block. When the sliding block moves into the second limiting groove inside the fixed block, release the collar to fix the wire inside the collar, thereby preventing the wire inside the analyzer from getting tangled. This avoids signal transmission interference or interruption caused by the wires squeezing, stretching or poor contact, ensuring the accuracy and stability of the oxygen analyzer's measurement data, and enabling the instrument to accurately detect and transmit oxygen concentration signals.

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0028] Reference Figure 1-6This utility model provides an anti-clogging oxygen analyzer, which includes an analyzer 1. Multiple fixing blocks 5 are fixedly connected inside the analyzer 1. A first limiting groove 8 and a second limiting groove 9 are opened inside the fixing blocks 5. A sliding block 10 is slidably connected inside the fixing blocks 5. Two springs 11 are fixedly connected to one end of the sliding block 10. A telescopic rod 12 is fixedly connected to one end of the sliding block 10. A collar 13 is fixedly connected to the outside of the sliding block 10.

[0029] Specifically: Pressing the collar 13 causes the sliding block 10 outside the collar to move in the first limiting groove 8 inside the fixed block 5. When the sliding block 10 moves into the second limiting groove 9 inside the fixed block 5, the collar 13 is released so that the wire 6 is fixed inside the collar 13, thereby preventing the wire 6 inside the analyzer 1 from getting tangled.

[0030] One end of the spring 11 is fixedly connected to the inside of the fixed block 5, and one end of the telescopic rod 12 is fixedly connected to the inside of the fixed block 5.

[0031] The analyzer 1 has a fixed internal connection to a sponge pad 7, and multiple wires 6 are installed inside the sponge pad 7.

[0032] Specifically: The wire 6 is installed in the groove inside the sponge pad 7 on the back side of the analyzer 1.

[0033] The analyzer 1 has a display screen 2 inside, and a housing 3 is fixedly connected to the rear side of the analyzer 1.

[0034] A dustproof mesh 4 is fixedly connected inside the outer casing 3, and multiple ventilation openings 14 are provided inside the outer casing 3.

[0035] Specifically: When the analyzer 1 has been used for a long time, dust will enter the analyzer 1 through the dustproof mesh 4 inside the rear outer casing 3.

[0036] The dustproof net 4 is externally rotatably connected to a drive rod 15, and the output end of the drive rod 15 is fixedly connected to a motor 16.

[0037] Specifically: Driven by the motor 16 and the drive rod 15, the external first gear 17 is rotated.

[0038] The drive rod 15 is externally fixedly connected to a first gear 17, and the first gear 17 is externally meshed with two second gears 18.

[0039] Specifically: the first gear 17 drives the second gear 18 at both ends to rotate, and the rotation of the second gear 18 drives the internal rotating rod 19 to rotate.

[0040] The second gear 18 is internally fixedly connected to a rotating rod 19, and the rotating rod 19 is externally fixedly connected to multiple scrapers 20.

[0041] Specifically: the scraper 20 outside the rotating rod 19 rotates and cleans the dust adhering to the surface of the dustproof net 4.

[0042] The analyzer 1 is externally fixedly connected to multiple buffer pads 21, the buffer pads 21 are externally fixedly connected to a protective plate 22, the buffer pads 21 are internally fixedly connected to a telescopic ring 23, and the telescopic ring 23 is externally slidably connected to a limiting block 24.

[0043] Working principle: The lead wire 6 is installed in the groove inside the sponge pad 7 on the rear side of the analyzer 1. Pressing the collar 13 causes the sliding block 10 outside the collar to move within the first limiting groove 8 inside the fixed block 5. When the sliding block 10 moves into the second limiting groove 9 inside the fixed block 5, the collar 13 is released, fixing the lead wire 6 inside the collar 13. This prevents the lead wire 6 from becoming tangled inside the analyzer 1, avoiding signal transmission interference or interruption caused by mutual compression, stretching, or poor contact of the lead wires 6. This ensures the accuracy and stability of the oxygen analyzer 1's measurement data, enabling the instrument to accurately detect and transmit oxygen concentration signals. Over time, dust may enter the analyzer 1 through the dustproof mesh 4 inside the rear outer casing 3. Inside the analyzer 1, a large amount of dust accumulates on the dustproof mesh 4 over a long period, causing blockage of the internal pores. Driven by the motor 16 and the drive rod 15, the external first gear 17 rotates, which in turn drives the upper and lower second gears 18. The rotation of the second gears 18 then drives the internal rotating rod 19, causing the scraper 20 outside the rotating rod 19 to rotate and clean the dust adhering to the surface of the dustproof mesh 4. This ensures that gas can enter the analyzer normally, allowing the sensor to accurately detect the oxygen concentration, guaranteeing the accuracy of the measurement results, reducing the workload of components such as the air pump, decreasing wear, and extending their service life. When an external object collides with the analyzer 1, the telescopic ring 23 inside the protective plate 22 is compressed and moves within the limiting block 24. A buffer pad 21 is connected to one end of the telescopic ring 23 to cushion the impact on the analyzer 1.

[0044] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
