FIELD: apparatuses for surface cleansing. SUBSTANCE: apparatus for surface cleansing has increased effectiveness of surfaces cleansing, simplified structure and expanded field of usage. Apparatus has washing head with plate-like body, that has porous flexible seal along perimeter and communicates through central hole with passive nozzle of vortex ejector, active nozzle of which communicates with atmosphere and ejector itself is connected to vacuum source through holes made in butt wall of its radial-slot diffuser, peripheral part of which is connected with discharge tank. Washing head body has calibrated metering orifice located inside it and connected with tank for washing liquid, and mounted inside body curvelinear blades forming nozzle apparatus with given direction of curling. In the case inner cavity of tank for washing liquid is connected with atmosphere and cavity of discharge tank is connected to vacuum source. Vacuum source (household air cleaner) through active nozzle provides intake of atmospheric air and its curling in near axis zone of ejector, that creates additional rarefaction in washing head, causing supply in it of washing liquid and air, that passes through porous seal. Simultaneously nozzle apparatus creates curling of liquid-air mixture in washing head intensifying its action on cleansed surface. In the case separation of gas from outgoing liquid-air mixture is carried out in radial-slot diffuser of ejector and pure liquid is carried off into discharge tank, that increases effectiveness of ejector operation and intensifies process of surface cleansing. Simplicity of design, economical efficiency, reliability and comfort of operation, absence of rotating operational details allows to expand the apparatus field of usage, to use it for soft surfaces washing in household and in medicine in particular. EFFECT: increased effectiveness of apparatus operation, simplified its design, expanded field of its usage. 3 dwg |
