However, there are still the following problems:

[0004] In the actual use of the above device, although the HEPA high-efficiency filter screen is used to achieve the filtering effect, when the HEPA high-efficiency filter screen filters the impurities in the air, the impurities will adhere to the HEPA high-efficiency filter screen.

Embodiment 1

[0031] The present utility model solves the problem that existing impurities will adhere to the HEPA high-efficiency filter screen. Over time, the impurities will cause blockage of the HEPA high-efficiency filter screen, and then lead to a decrease in the air permeability of the HEPA high-efficiency filter screen. By moving the push rod 11, the impurities adsorbed on the filter screen 14 can be cleaned, thus avoiding the blockage of the filter screen 14, and discloses:

[0032] Detector body 1, an air pipe 2 is nested at the top of the detector body 1, and a probe 3 is in interference fit with the top of the air pipe 2; further comprising: a bracket 4 is fixed inside the probe 3, and the right end of the bracket 4 is connected to an impeller 5 through a bearing, and the left end of the impeller 5 is connected to the middle of a rotating rod 7 through a tapered wheel set 6. The outer end of the rotating rod 7 extends into the inside of the probe 3 to form a rotating mechanism, and a sector gear 8 is key-connected to the outer end of the rotating rod 7. One end of the sector gear 8 meshes with a collar 9, and the collar 9 slides inside the probe 3. The left end of the collar 9 is welded with a push rod 11, the push rod 11 slides inside the probe 3, and the outer end of the push rod 11 abuts against a receiving block 12, and the receiving block 12 slides inside the probe 3. The outer end of the receiving block 12 is connected to a first spring 13, and the left end of the first spring 13 is connected inside the probe 3. The inside of the receiving block 12 abuts against a filter screen 14. The upper and lower ends of the collar 9 are provided with balls 10 at equal intervals, and the outer ends of the balls 10 abut against the inside of the probe 3;

[0033] Reference Figures 1 to 5, turn on the detector body 1, insert the probe 3 into the insulation layer of the film cabin, and then through the built-in blades of the detector body 1, the gas in the insulation layer of the film cabin can enter the detector body 1 through the inside of the trachea 2 for detection, so as to detect the oxygen content in the insulation layer of the film cabin. The gas passing through the probe 3 will drive the impeller 5 to rotate, and then the rotation of the impeller 5 will drive the rotating rod 7 to rotate through the conical pulley set 6. Then, the rotation of the rotating rod 7 will drive the sector gear 8 to rotate, and then the rotation of the sector gear 8 will drive the collar 9 to move. The collar 9 slides inside the probe 3 through the ball 10, so that the movement of the collar 9 drives the ejector rod 11 to move. Through the sector gear 8, the collar 9 can move reciprocally, so that the ejector rod 11 moves to push the receiving block 12 to move, and then the receiving block 12 moves to squeeze the first spring 13, so that the first spring 13 is compressed under force. When the collar 9 moves to the right, the first spring 13 then pushes the receiving block 12 to reset, so that the movement of the receiving block 12 drives the filter screen 14 to vibrate, and then the impurities adsorbed on the filter screen 14 can be cleaned, thus avoiding the blockage of the filter screen 14; Embodiment 2

[0034] The present utility model solves the problem that the existing filter screen 14 is connected by means of a buckle, resulting in inconvenient disassembly of the filter screen 14. Through the engagement of the slider 15, the replacement of the filter screen 14 is facilitated, and discloses:

[0035] The outer end of the filter screen 14 is fixed with a slider 15, and the slider 15 is vertically arranged. The outer end of the slider 15 extends into the inside of the chute 16 to form an engaging mechanism, and the chute 16 is opened in the receiving block 12. One end of the chute 16 is provided with symmetric openings, and the diameter of the openings on the chute 16 is larger than the diameter of the slider 15;

[0036] Reference Figure 2 , Figures 5 to 7 , by rotating the filter screen 14, the rotation of the filter screen 14 drives the slider 15 to rotate, and then the rotation of the slider 15 can slide in the chute 16. After rotating to the position, the rotation of the slider 15 is disengaged from the engagement with the chute 16, and then the filter screen 14 is pulled to make the filter screen 14 move out of the engagement with the chute 16, and then the filter screen 14 can be removed from the receiving block 12 for replacement. Then, reverse the above operations, and the filter screen 14 can be conveniently installed; Embodiment 3

[0037] The present utility model solves the problem that the engagement stability between the slider 15 and the chute 16 in Embodiment 2 is poor. Through the engagement between the convex block 17 and the groove 18, the engagement stability between the slider 15 and the chute 16 is improved, and discloses:

The inner end of the convex block 17 is semicircular in shape, and a second spring 19 is connected to the outer end of the convex block 17, and the outer end of the second spring 19 is connected inside the receiving block 12;

[0039] Reference Figure 2 、 Figures 5 to 7 When the slider 15 rotates, it will drive the groove 18 to rotate. Subsequently, the groove 18 rotates and squeezes the convex block 17, so that the convex block 17 is squeezed and slides into the interior of the receiving block 12. When the convex block 17 moves, it will squeeze the second spring 19, so that the second spring 19 is compressed under force. And when the convex block 17 moves, it will disengage from the clamping of the groove 18, thus facilitating the sliding of the slider 15. By reversing the above operations, the second spring 19 can then push the convex block 17 to extend into the interior of the groove 18 to form a clamp, thereby improving the clamping stability between the slider 15 and the chute 16.

[0040] Working principle: When using the oxygen content detection device for the thin film cabin insulation layer, first, reference Figures 1 to 5 Open the detector body 1, insert the probe 3 into the thin film cabin insulation layer. Then, through the blades built into the detector body 1, the gas in the thin film cabin insulation layer can enter the detector body 1 through the interior of the air pipe 2 for detection. When the gas passes through the probe 3, it will drive the impeller 5 to rotate. Subsequently, the rotation of the impeller 5 drives the rotating rod 7 to rotate through the conical pulley set 6. Then, the rotation of the rotating rod 7 drives the sector gear 8 to rotate. Through the sector gear 8, the collar 9 can move reciprocally. When the collar 9 moves to the right, the first spring 13 then pushes the receiving block 12 to reset, so that the movement of the receiving block 12 drives the filter screen 14 to vibrate, thereby cleaning the impurities adsorbed on the filter screen 14 and avoiding the blockage of the filter screen 14;

[0041] Reference Figure 2 、 Figures 5 to 7 By rotating the filter screen 14, the rotation of the filter screen 14 drives the slider 15 to rotate. After rotating to the position, the slider 15 rotates to disengage from the clamping of the chute 16. Then, pull the filter screen 14, and the filter screen 14 can be removed from the receiving block 12 for replacement. Then, reverse the above operations, and the filter screen 14 can be conveniently installed.

[0042] Reference Figure 2 、 Figures 5 to 7, the rotation of the slider 15 will drive the groove 18 to rotate, and then the rotation of the groove 18 will squeeze the convex block 17, so that the convex block 17 is squeezed and slides into the inside of the receiving block 12. And the movement of the convex block 17 will disengage from the engagement with the groove 18, thereby facilitating the sliding of the slider 15. By reversing the above operations, the stability of the engagement between the slider 15 and the chute 16 is improved.
