#CMT# #/CMT# The device for producing a foam associated with a pump, comprises a first filtering net (1a) disposed through an expulsion conduit (C2a), a second filtering net disposed in a downstream of the first net, and a removable tip extension. The first net is associated with a unit for supplying a flow of air in an upstream of the net with respect to a flow of liquid, and flexible to oscillate when the liquid expelled through the first net to mix the liquid with air and produce the foam. The pump comprises a reservoir containing a foaming liquid, and a pumping unit having a pump activation lever. #CMT# : #/CMT# The device for producing a foam associated with a pump, comprises a first filtering net (1a) disposed through an expulsion conduit (C2a), a second filtering net disposed in a downstream of the first net, and a removable tip extension. The first net is associated with a unit for supplying a flow of air in an upstream of the net with respect to a flow of liquid, and flexible to oscillate when the liquid expelled through the first net to mix the liquid with air and produce the foam. The pump comprises a reservoir containing a foaming liquid, and a pumping unit having a pump activation lever to suction the liquid and expel the liquid through the conduit to a minimum determined speed. The supplying unit comprises a chamber (72a) that leads the air in the conduit, and a passage to supply the air communicated with the external air of the distribution conduit and by which the air is sucked during the passage of liquid expelled by an inlet. The chamber comprises an expulsion opening (52a) laid out into the conduit and closed by the first net, and a peripheral zone connected to a wall of the conduit in an upstream of the opening. The removable tip extension is moved in translation between holding and determining positions respectively to produce a jet of foam. The passage of air is disposed in the extension at the junction of an expulsion head (2). The conduit in the tip has a removable section shrinkable towards the opening. The first net comprises central disc connected to the periphery of the net by thin elastic bands. The second filtering net is flexible and disposed in a downstream of the first net with respect to the flow of the liquid. The first and the second filtering nets are rounded and curved towards the outside. The peripheral zone of the second net is connected to an edge of the opening or to the wall of the conduit. #CMT#USE : #/CMT# The device is useful for producing a foam associated with a pump (claimed), which is useful for projecting household cleaning products on glass or clothes or in the field of cosmetics and projecting a haze of solar oil on the skin. #CMT#ADVANTAGE : #/CMT# The device is simple and cost effective to produce a light and dense foam used in the cosmetics. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows the pump lever of the device. 1a : First filtering net 2 : Expulsion head C2a : Expulsion conduit 52a : Expulsion opening 72a : Chamber. |
