Mist Blower Nozzle With Facing Body For Fine Atomization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mist blowers suffer from inefficient atomization of liquid, with larger particle sizes forming when liquid separates from the nozzle's front end surface, leading to inconsistent atomization patterns.
Innovation Solution
A mist blower configuration featuring a liquid nozzle with a constricted passage and a facing body, where the liquid collides on the facing surface and flows onto the facing body side surface, utilizing air flow to atomize the liquid into finer particles, and a manufacturing method involving a press-fitted press-in body and cutting process to define openings for efficient liquid separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If liquid is ejected from the ejection hole and flows on the front end surface to the corner part of the liquid nozzle, then the liquid is atomized at the corner part, but the particle size of the liquid that separates off near the ejection hole is larger than desired
Solution Approach 1:
The liquid nozzle is divided into functionally distinct regions: a front end surface for initial liquid flow, a corner part for atomization, and a newly introduced facing body with a facing surface positioned opposite the ejection hole. This segmentation allows different portions of the nozzle to perform specialized functions, with the facing body specifically designed to control liquid separation and reduce large particle formation.
Solution Approach 2:
The invention introduces a new spatial dimension by adding the facing body that extends in a direction substantially perpendicular to the front end surface. This creates a three-dimensional liquid control path where liquid can be ejected, flow on the front end surface, then be redirected by the facing surface, providing additional control over liquid trajectory and separation characteristics to achieve finer, more uniform particle sizes.
2Manufacturing precision
If a facing body is added to improve liquid atomization, then fine particle atomization is achieved, but the device complexity increases
Solution Approach 1:
The facing body is integrated with the liquid nozzle as a unified component, with the facing surface forming a continuous structure with the front end surface and corner part. This merging approach allows the additional functional surface to be added without significantly increasing overall device complexity, as it becomes part of the nozzle's integrated geometry rather than a separate auxiliary component.
Solution Approach 2:
The invention optimizes specific geometric parameters of the facing body, including the position of the facing surface opposite the ejection hole, the angle of the facing surface relative to the front end surface, and the dimensions of the corner part. By carefully controlling these parameters, the facing body achieves effective liquid atomization while minimizing the increase in device complexity through precise dimensional design.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The configuration ensures stable and fine atomization of liquid, preventing accumulation and maintaining airflow speed to produce particles of 50 micrometers or smaller, enhancing the mist blower's performance.
Implementation Method 1
the liquid ejected from the ejection hole collides on the facing surface of the facing body and flows on the facing surface to the facing body side surface. The liquid then separates off of the facing body by the air delivered by the fan.
Implementation Method 2
The liquid then separates off of the facing body by the air delivered by the fan. Consequently, the liquid can be atomized.
Implementation Method 3
a liquid passage through which the liquid flows and which comprises a constricted part having a minimum diameter; and the liquid may be ejected from an ejection hole of the constricted part
Implementation Method 4
press-fitting the press-in body into the second aperture part to a position that is a predetermined distance away from the constricted part; and after the press-fitting, cutting the base body in a second direction perpendicular to the first direction
