Detailed implementation mode

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] The present invention provides an oxygen content analyzer that is convenient for cleaning as shown in Figures 1 to 5 Figure 1. It includes a detection probe 1 of the analyzer. A plurality of air inlet holes 2 are opened on the surface of the detection probe 1. A fixing seat 3 is installed at one end of the detection probe 1 away from the air inlet holes 2. A cleaning frame 4 is arranged outside the detection probe 1. A cleaning sponge 5 is filled in the inner cavity of the cleaning frame 4. Through holes 6 and sewage discharge holes 7 are respectively opened at the centers of the top and bottom of the cleaning frame 4. Fixing tubes 8 are fixed on both sides of the inner cavity of the cleaning frame 4. A movable column 9 is movably arranged inside the fixing tube 8. One end of the movable column 9 penetrates through the cleaning frame 4 and extends outwards;

[0023] Through the setting of the cleaning frame 4, not only can the cleaning sponge 5 be stored, the cleaning liquid can be absorbed by the cleaning sponge 5, the detection probe 1 can be immersed in the cleaning liquid, and then by moving the cleaning frame 4, the stains on the surface can be scraped off, accelerating the speed of stain shedding. At the same time, the movable column 9 is inserted into the air inlet holes 2, and the stains inside the air inlet holes 2 are cleaned by rotation, achieving the purpose of quickly cleaning the stains on the surface of the detection probe 1.

[0024] A receiving groove 10 is opened in the inner cavity of the fixing tube 8. A limiting ring 11 is fixed on the surface of the movable column 9. A support spring 12 is sleeved outside the movable column 9. The support spring 12 is located in the receiving groove 10 and supports the limiting ring 11. Through the setting of the support spring 12 and the limiting ring 11, it is convenient to limit the movable column 9, ensure the outward movement of the movable column 9, and avoid the cleaning block 13 at the end of the movable column 9 scratching the outer surface of the detection probe 1 when moving the cleaning frame 4.

[0025] Cleaning blocks 13 are fixed at the opposite ends of the movable column 9. The cleaning blocks 13 are arranged in a ring along the end of the movable column 9. Through the cooperation of the cleaning blocks 13, it is convenient to break and clean the stains in the air inlet holes 2, so as to prevent the cleaning sponge 5 from being unable to wipe off the stains inside the air inlet holes 2 and improve the cleaning efficiency of the movable column 9.

[0026] A through hole 14 is opened inside the movable column 9. A sealing plug 15 is clamped in the inner cavity of the through hole 14. Through the through hole 14, the agglomerated stains cleaned by the cleaning blocks 13 inside the air inlet holes 2 can be discharged, avoiding the stains being difficult to be discharged from the sewage discharge hole 7 due to the extrusion of the cleaning sponge 5.

[0027] A pressing plate 16 is fixed to the end of the movable column 9 away from the cleaning frame 4. The surface of the pressing plate 16 away from the movable column 9 is provided with anti-slip grooves. Through the cooperation of the pressing plate 16, the movable column 9 is conveniently moved, the movable column 9 is squeezed inward and the cleaning block 13 is moved into the air inlet 2, and then the anti-slip grooves on the surface are used to increase the friction between the squeezing plate and the movable column 9. The movable column 9 is rotated, and the stains inside the air inlet 2 are rotated and cleaned through the cleaning block 13.

[0028] The aperture of the through hole 6 is the same as the outer diameter of the detection probe 1, and the aperture of the drain hole 7 is larger than the aperture of the through hole 6. By limiting the apertures of the through hole 6 and the drain hole 7, it is ensured that the cleaning frame 4 is stably mounted on the outside of the detection probe 1, and then the stains on the outside of the detection probe 1 can only be discharged through the drain hole 7.

[0029] A cleaning liquid adding port 17 is provided at the top of the cleaning frame 4, and a rubber plug 18 is filled in the cleaning liquid adding port 17. Through the setting of the cleaning liquid adding port 17, it is convenient to add cleaning liquid to the cleaning frame 4, and it is convenient to immerse the detection probe 1 in the cleaning liquid, so that the stains on the surface can be quickly softened and fallen off.

[0030] During specific use, the cleaning frame 4 is put on the outside of the detection probe 1, and then the rubber stopper 18 is opened, and cleaning liquid is added to the cleaning frame 4. The cleaning liquid is absorbed by the cleaning sponge 5, and then the detection probe 1 is immersed in the cleaning liquid. By moving the cleaning frame 4 back and forth, not only can all parts of the detection probe 1 be immersed in the cleaning liquid, but the softened stains can also be cleaned at the same time. When the stains on the surface of the detection probe 1 are cleared, the cleaning frame 4 is moved to the position of the air inlet 2, and the extrusion plate is pressed to make the movable column 9 drive the cleaning block 13 to move into the air inlet 2. After the stains in the air inlet 2 are softened by being soaked in the cleaning liquid, the movable column 9 is rotated and the cleaning block 13 is used to discharge the stains from the air inlet 2 along the through hole 14.

[0031] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may 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.
