Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

It should be noted that all the directional indicators (such as upper, lower, left, right, front and rear …) in the embodiment of the present invention are only used to explain the relative position relationship between the components, the motion situation, etc. in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indicator is changed accordingly. In addition, the descriptions related to "preferred", "less preferred", etc. in the present invention are for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicit ly indicating the number of technical features indicated. Thus, a feature defined as "preferred" or "less preferred" may explicitly or implicitly include at least one such feature.

Referring to fig. 1 and 2, a disinfectant manufacturing machine is provided with a T-shaped or Y-shaped disinfectant nozzle 2, one end of the nozzle is provided with a nozzle 4, and the disinfectant nozzle 2 is further provided with an installation structure of a screwing cap 1.

Referring to fig. 3 to 5, the screwing cap 1 mounting structure includes a screwing cap 1 and a housing 3 of a disinfectant nozzle 2. The casing 3 is T-shaped or Y-shaped, a tubular nozzle shell 31 is formed at the left part of the casing 3, an axial sliding groove 311 and a circumferential sliding groove 312 communicated with the axial sliding groove 311 are arranged on the nozzle shell 31, the axial sliding groove 311 is a semi-through groove or a through groove, one end of the axial sliding groove 311 extends to the end surface of the head end of the nozzle shell 31, the head end of the nozzle shell 31 is sleeved with the screwing cap 1, a convex block 11 capable of being installed into the circumferential sliding groove 312 along the axial sliding groove 311 is arranged on the inner side wall of the screwing cap 1, and a buckling position 313 capable of limiting the convex block 11 to be disengaged from the circumferential sliding groove 312 is arranged in the circumferential sliding groove 312.
