Description

Technical Field

[0001] The present application relates to the field of nozzles, and in particular to a Venturi nozzle used for a powered dry mist hydrogen peroxide disinfection method. Background Art

[0002] The working principle of the existing spray is that the air inlet pipe and the liquid suction pipe are arranged vertically. When the high-speed airflow of the air inlet pipe passes through the top of the suction pipe, a vacuum is generated on the top of the suction pipe, sucking the liquid out of the container, and the high-speed airflow sprays the liquid out at the same time.

[0003] The above design only decomposes the liquid in the process of spraying out to produce mist particles. Such particles have a diameter of more than 100um and are still in liquid state and cannot diffuse in the air. When disinfecting a specific space to be disinfected, it is not convenient for the disinfectant to spread throughout the entire disinfected space. Utility Model Content

[0004] In order to improve the problem that the particles sprayed by the existing spray device are still in liquid state and cannot diffuse in the air, the present application provides a Venturi nozzle for a powered dry mist hydrogen peroxide disinfection method.

[0005] The present application provides a venturi nozzle for a powered dry mist hydrogen peroxide disinfection method using the following technical solutions:

[0006] A venturi nozzle for a powered dry mist hydrogen peroxide disinfection method comprises a venturi nozzle body, the body is provided with a bottle mouth interface and an air inlet interface, the body comprises a nozzle main seat body and an external atomizing nozzle, the body is provided with a mounting port, the nozzle main seat body is arranged in the mounting port, the external atomizing nozzle is fixed to the side wall of the mounting port, the nozzle main seat body is provided with a plurality of small holes, and the surface of the external atomizing nozzle is provided with a spray hole and a plurality of annular holes for generating vortices, and the annular holes are arranged obliquely.

[0007] In one embodiment, the mounting port, the nozzle main body and the external atomizing nozzle form a nozzle, and the body is provided with a forward nozzle and a side nozzle, the forward nozzle is coaxially arranged at the end of the body, and the side nozzle is vertically arranged on the side wall of the body.

[0008] The Venturi nozzle for the powered dry mist hydrogen peroxide disinfection method provided in the embodiments of the present disclosure can achieve the following technical effects:

[0009] The fan driven by the vacuum motor generates a high-pressure airflow that enters the main body from the air inlet interface, and then the airflow passes through the small hole in the main body of the nozzle and is ejected from the annular hole of the Venturi nozzle to generate a vortex. At the same time, the airflow generates a vacuum suction force on the bottle mouth interface, sucking the hydrogen peroxide liquid in the container into the vortex. At this time, the hydrogen peroxide liquid collides with each other at high speed in the vortex area to generate dry mist particles with a diameter of less than 10um. At the same time, the high-speed gas is ejected in a straight line from the ejection hole of the external atomizing nozzle, ejecting the dry mist particles into the vortex. Through the above device, the liquid can be decomposed into dry mist particles during the ejection process and diffused into the entire sterilization space, and the dry mist particles can diffuse in the air for a long time, which is convenient for disinfection and sterilization.

[0010] The above general description and the following description are exemplary and explanatory only and are not intended to limit the present application. BRIEF DESCRIPTION OF THE DRAWINGS

At the same time, the airflow generates a vacuum suction force on the bottle mouth interface 2, sucking the hydrogen peroxide liquid in the container into the vortex. At this time, the hydrogen peroxide liquid collides with each other at high speed in the vortex area to generate dry mist particles with a diameter of less than 10um.
