Example (b): air quality detection device of air duct machine, as shown in fig. 1-4, including a detection cylinder 11, the below fixedly connected with of detection cylinder 11 has narrow first wedge pipe 12 down wide, the inside sliding connection of first wedge pipe 12 has hollow push rod 13, the top fixedly connected with handle 14 of hollow push rod 13, the outer fixedly connected with four dead levers 17 of lateral wall at the other end of hollow push rod 13, the outer end fixedly connected with ring 18 of four dead levers 17, the outside fixedly connected with rubber ring 19 of ring 18, the diameter of rubber ring 19 slightly is greater than the inside diameter of detection cylinder 11, rubber ring 19 and detection cylinder 11 realize interference fit, the inside sliding connection of hollow push rod 13 has breather pipe 15, the one end of breather pipe 15 stretches into inside first wedge pipe 12, the other end of first wedge pipe 12 upwards extends and fixedly connected with butt joint cover 16, breather pipe 15 is the material of PE hose, the inside sliding mounting of detection cylinder 11 has first filter screen 20, the below fixedly connected with of first filter screen 20 has four connecting rods 21, the other end fixedly connected with second filter screen 22 of four connecting rods 21, the mesh diameter of first filter screen 20 is greater than the mesh diameter of second filter screen 22. During operation, the staff can block the butt joint cover 16 at the pipeline opening of the ducted air conditioner, the air enters the air pipe 15 from the butt joint cover 16, and then enters the first wedge-shaped pipe 12 from the air pipe 15, because the first wedge-shaped pipe 12 presents a wedge shape with a narrow upper part and a narrow lower part, the flow rate of the air can be reduced after entering the first wedge-shaped pipe 12, so that the air falls onto the first filter screen 20, the effect of adsorbing larger dust particles in the air is achieved through the first filter screen 20, the air continues to circulate on the detection cylinder 11 times after passing through the first filter screen 20, and then passes through the second filter screen 22, the second filter screen 22 adsorbs dust with smaller particles in the air, and then the staff can push the handle 14, so as to drive the hollow push rod 13 to slide inside the first wedge-shaped pipe 12, and further drive the circular ring 18 and the rubber ring 19 to slide on the inner side wall of the detection cylinder 11, on the one hand, the dust on the inner side wall of the detection cylinder 11 can be cleaned, on the other hand, the first filter screen 20, the connecting rod 21 and the second filter screen 22 can be pushed inside the detection cylinder 11, which is convenient for pushing out of the sampling of the laboratory staff, and the subsequent sampling is convenient for the laboratory staff. Through such design, carry out the filtration sampling detection work to the dust granule of different granule sizes, facilitated the sampling and detected getting of filter element and put the flow, on the other hand can also clear up the dust that is stained with on the detector inner wall and attaches, avoids remaining the influence of dust to next detection achievement. Detect a barrel 11's below through screw thread swing joint have detachable go up wide narrow second wedge pipe 23 down, the below fixedly connected with outlet duct 24 of second wedge pipe 23, the centre of outlet duct 24 is provided with butt joint pipe 25, butt joint pipe 25's below fixedly connected with gas outlet 28, butt joint pipe 25 is inside to be offered than 24 inside bigger cavitys of outlet duct, butt joint pipe 25 is inside to be offered four springs 27 of fixedly connected with on the inside bottom surface of bottom surface, four springs 27's top fixedly connected with sprue 26, sprue 26 surface coating has the rubber layer, sprue 26 closely laminates the below to outlet duct 24, the diameter of sprue 26 is greater than outlet duct 24's diameter and is less than butt joint pipe 25's diameter. When the gas filter works, gas enters the second wedge-shaped pipe 23 through the second filter screen 22, then enters the gas outlet pipe 24, and finally enters the butt joint pipe 25, when the gas passes through the gas outlet pipe 24, the gas pressure is increased, so that the blocking block 26 and the spring 27 are compressed downwards, a gap is formed between the blocking block 26 and the gas outlet pipe 24, and the gas normally circulates. When the ducted air conditioner stops working gradually, the spring 27 begins to rebound, and then the blocking block 26 is driven to reset and is attached to the air outlet pipe 24 again.

The utility model discloses a work flow:

the first step is as follows: the staff can be with the pipeline mouth of butt joint cover 16 block at the tuber pipe machine, the air is from butt joint cover 16 entering breather pipe 15, in getting into first wedge-shaped pipe 12 in the breather pipe 15 again, because first wedge-shaped pipe 12 presents the wedge of narrow money down, the air can reduce the velocity of flow after getting into first wedge-shaped pipe 12 inside, thereby fall on first filter screen 20, play the effect of adsorbing bigger dust particle in the gas through first filter screen 20, the air continues to circulate in detecting a section of thick bamboo 11 through first filter screen 20, then through second filter screen 22, second filter screen 22 adsorbs the less dust of granule in the air, then the staff can promote handle 14, thereby drive hollow push rod 13 and slide in first wedge-shaped pipe 12 is inside, and then drive ring 18 and rubber ring 19 and slide on detecting a section of thick bamboo 11's inside lateral wall, on the one hand can clear up the dust on detecting a section of thick bamboo 11 inside lateral wall, can push out first filter screen 20, connecting rod 21 and second filter screen 22 from detecting a section of thick bamboo 11 inside, convenience is tested personnel's sampling, subsequent detection work.

The second step is that: inside gas passes through second filter screen 22 and gets into second wedge pipe 23, and then it is inside to get into outlet duct 24, get into last inside the butt joint pipe 25, gas is when passing outlet duct 24, atmospheric pressure increases, thereby make blockking 26 and spring 27 compress downwards, the gap appears between blockking 26 and outlet duct 24, gaseous normal circulation, when tuber pipe machine stop work gradually, spring 27 begins to kick-back, and then drive blockking 26 and reset, laminate mutually with outlet duct 24 again, avoid the air reflux.

The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
