The specific embodiment
In order to make those skilled in the art person understand the utility model scheme better, and make the above-mentioned purpose of the utility model, feature and advantage can be more obviously understandable, below in conjunction with accompanying drawing and embodiment the utility model done further detailed explanation.
Embodiment:
Like Fig. 1, shown in Figure 2, delayer 1 and delayer 9 are arranged at the two ends of dust falling device respectively, being configured to of delayer 1 (structure of delayer 9 is identical with delayer 1): housing is provided with delayer handle 11; Air inlet port a, gas outlet c, gas outlet d; Pressure relief opening b, pressure relief opening e, wherein; Pressure relief opening e is provided with control valve, is used to regulate the gas output of pressure relief opening e, and delayer handle 11 is used to control the switch of gas outlet c and gas outlet d; Promptly gas outlet d closes when gas outlet c opens, and gas outlet d opens when gas outlet c closes; Pressure relief opening e adjusted valve has determined the length that delayer is delayed time, and promptly the control valve gas output is little, and the switch transition of gas outlet c and gas outlet d is slow, and the delayer delay time is long, and vice versa.
The air inlet port a of delayer 1 connects air inlet pipe 2, and air inlet pipe 2 is led to gas main 21 (see figure 2)s,
The controller that the gas outlet c of delayer 1 connects controllers 4 through tracheae 3 holds one's breath mouthfuls 41; The gas outlet d of delayer 1 connects the air inlet port a of delayer 9 through tracheae 10; The controller that the gas outlet c of delayer 9 connects controllers 4 through tracheae 8 holds one's breath mouthfuls 41, and the gas outlet d of delayer 9 connects controllers through tracheae 7 and opens gas port 42.
