Disclosed are a ventilation test device and method for plastic parts of a coffee machine. The device includes a device body, a detection assembly on a top of the device body, gas delivery pipes on a top of the detection assembly, electric telescopic columns, and a pressing plate on tops of telescopic ends of the electric telescopic columns. Circular holes are formed in the pressing plate, telescopic rings are fixedly mounted at a bottom of the pressing plate, and the telescopic rings are located around peripheries of the circular holes. Downstream devices for identifying ventilation types are arranged inside the gas delivery pipes, annular inclined plates are arranged on the pressing plate, the annular inclined plates are distributed around peripheries of tops of the circular holes, and a U-shaped frame is hingedly connected to a top of an inclined plate in each of the annular inclined plates.

The present invention provides a human-derived molecularly modified insecticidal protein, and a preparation method and application thereof, and belongs to the field of genetic engineering and biological control. The present invention provides a human-derived molecularly modified insecticidal protein, and the amino acid sequence of the insecticidal protein CCL-CCL_scFv is shown as SEQ ID No. 1. The insecticidal protein CCL-CCL_scFv shows significantly higher affinity with midgut BBMV ofthan Cry1Ab toxin, competes with Cry1Ab and Cry1Ac toxins for binding the midgut BBMV of, and is a mimic of Cry1Ab and Cry1Ac toxins. Throughindoor insecticidal biological activity assay, the insecticidal protein shows a good insecticidal effect, and can effectively replace Cry1Ac or Cry1Ab toxin for biological control of insect pest.
