Compared with the nozzle structure in the prior art, the nozzle provided by the embodiment of the utility model has the advantages that the horn head and the nozzle cover body are arranged at the spraying end of the nozzle, the nozzle cover body is opened when spraying operation is carried out, the nozzle cover body is closed after spraying is finished, and a negative pressure closed environment is formed at the nozzle under the combined action of the horn head and the nozzle cover body. Because the adhesive force of the microbial inoculum at the nozzle opening and the combined action of the negative pressure environment, the microbial inoculum is remained at the horn head, in the closed environment, the liquid in the microbial inoculum is not easy to evaporate, and the separated powdery microbial inoculum is prevented from blocking the nozzle, thereby avoiding the heavy work of manually dredging the nozzle.

It should be noted that, in this embodiment, the nozzle is inclined at a certain angle during installation, for example, the nozzle is placed at an angle shown in fig. 1, so that the sprayed microbial inoculum is in a parabolic shape, and the area sprayed by the microbial inoculum is the largest. And the nozzle that sets up like this, the residual microbial inoculum of department at the horn head is changeed and is kept, can reach the better purpose that prevents that microbial inoculum (medicament) from appearing powder after the mummification.

In one specific embodiment, and as shown in fig. 2A, the nozzle tube 12 includes: a first section 111 near the horn head 12 and a second section 112 connected to the first section 111; the first section 111 has a smaller aperture than the second section 112.

In this embodiment, the first segment and the second segment of the nozzle pipe may be integrally formed, or may be divided into different parts to be connected together, and the connection portion may have an arc transition, which is not particularly limited in this embodiment. Combine fig. 2B to show, this application inventor finds that when carrying out the structural design to the nozzle pipe, for the convenience of the microbial inoculum backward flow after form negative pressure environment in horn head department, the thick thin nozzle pipe of one end or the form of falling the horn head is designed into to the tube-shape nozzle pipe that will have the thickness even, and thin one end is close to the horn head, so both made things convenient for the microbial inoculum backward flow, also be convenient for form vacuum environment in the thin one end of nozzle pipe, remain the microbial inoculum when horn head adhesive force and negative pressure adsorption affinity keep balance, it stores in horn head department to remain the microbial inoculum. As shown in fig. 2B, wherein a is a reflux microbial inoculum, B is a residual microbial inoculum, and C is vacuum.

In another alternative embodiment, the first segment 111 of the nozzle tube 11 may be directly connected to the flare 12, referring to the schematic structure shown in fig. 2A; for better forming the negative pressure environment, as shown in fig. 3A, the nozzle tube 11 may further include a third segment 113, two ends of the third segment 113 are respectively connected to the first segment 111 and the bell end 12, and the third segment 113 is cylindrical. Of course, the first section, the second section, and the third section in this embodiment may also be integrally formed, or may also be connected together after being segmented into different components, which is not limited in this embodiment. Referring to fig. 3B, after the nozzle cover body is closed, after a plurality of tests, the inventor can more easily form a vacuum environment at the third section, and can more easily store the residual microbial inoculum at the nozzle opening. Wherein A is a reflux microbial inoculum, B is a residual microbial inoculum, and C is vacuum.

In another alternative embodiment, as shown in fig. 4, the projected length d1 from the side of the flare 12 connected to the nozzle cover 13 to the axis of the nozzle tube 11 is less than the projected length d2 from the side of the flare 12 connected to the nozzle cover 13 to the axis of the nozzle tube 11. In the embodiment of the utility model, in order to facilitate the nozzle cover body to be opened during the spraying operation, the inventor designs the horn head into an asymmetric shape, such as a bird beak shape or a notch arranged at the joint of the horn head and the nozzle cover body. Thus, the projection length d1 from one side of the connecting piece 14 to the axis of the nozzle pipe is less than the projection length d2 from the opposite side to the axis of the nozzle, and the nozzle cover body is easier to be opened due to the change of the self-gravity of the nozzle cover body and the moment during spraying.

In another embodiment, a better sealing environment is formed for the purpose of sealing in conformity with the flare head when the nozzle cover is closed. The inventor of the embodiment also arranges a groove at the edge of the horn head 12, and a bulge corresponding to the groove is arranged on the nozzle cover body 13; or the edge of the horn head is provided with a bulge, and the nozzle cover body is provided with a groove corresponding to the bulge.
