as shown in fig1 one or more bombs 1 are arranged with their lower part 4 inserted into a suitable seat 2 of a housing body 3 . each lower part 4 of the relative bomb 1 is designed to receive the lacquer to be atomized . for example , part 4 may be screwed to a head part 5 containing the atomizing mechanism to be described hereinafter . fig2 shows the bombs 1 seated in the seats 2 provided in the front part of the housing body 3 . the said housing body 3 has in its rear part a bay 6 suitably designed for receiving a means for the generation of a compressed - air flow , for example a piston compressor ( not shown ). the outflow side of the compressor is connected by means of a suitable hose 7 to the atomizing head 5 ( fig4 ). the atomizing head 5 comprises a union 8 for connecting the corresponding hose 7 . same union leads to a valve 14 which is controlled by a flat movable cover 9 part of the atomizing head 5 . when exerting a pressure on the cover 9 in direction of the arrow f ( fig2 ), the valve 14 will be opened allowing the compressed air to flow from the hose 7 toward the removable spraying nozzle unit 10 and allowing at the same time the lacquer to be expelled in the form of an atomized veil 11 . for the purpose , the valve body is provided with a peripheral groove 14a open on the outside . advantageously , the hoses 7 surround the corresponding bomb 1 in form of a spiral , allowing the easy extraction of the bomb 1 from its corresponding seat 2 or vice versa , the reseating of the bomb 1 together with its hose 7 into the seat 2 . fig3 schematically illustrates the compressed - air supply circuit leading to the atomising head 5 of the two bombs 1 . from a source of compressed air , for example a compressor 12 , a supply hose 13 leads to a ` y `- ramification 13a , whose ramification branches are connected to the flexible hoses 7 leading toward the corresponding atomizing heads 5 . advantageously , the ramification 13a is incorporated within the housing body 3 , with only the unions for the connection of the hoses 7 being left free ( fig4 ). fig4 shows a cross - sectional detail of the atomizing head 5 , in particular the compressed - air flow check valve . the movable cover 9 of the head 5 allows to operate a spindle valve indicated by 14 . the shaft 15 of the said valve , is biased to closed position by a spring 16 in . when pressing the cover 9 in the direction of the arrow f , against the thrust of a spring means 17 , the shaft 15 is pushed down allowing the flow of compressed air from the hose 7 , through the valve 15 , to a channel 18 in the head leading to the atomizing nozzle unit 10 . as shown in fig5 the removable atomizing nozzle unit 10 of the head 5 is formed of a first flow duct 19 connectable to the channel 18 for the compressed - air supply . in addition , the nozzle unit 10 is provided with a second inlet duct 20 leading to the lacquer in the bomb 1 and drawing lacquer therefor the venturi principle . the end 19a of the nozzle for the compressed air duct 19 is closed to the orifice end 20a of the nozzle for the aspirated lacquer duct 20 . the duct 20 , 20a for drawing the lacquer ends in an upper cone 21 , separated by a vertical notch 22 from the orifice 19a of the duct 19 . the vertical notch 22 is most important for the safe operation of the nozzle unit 10 , because it is this vertical notch 22 which allows the perfect and really surprising atomising effect . the cone 21 containing the orifice 20a of the duct 20 prevents the formation of droplets at the end of of the atomizing phase and therewith prevents the blocking of the ducts 19 , 19a , 20 , 20a .
means for atomizing cosmetic products , in particular hair lacquers , in which each bomb to be filled with hair lacquer to be atomized is provided with a controllable valve as well as with an atomizing nozzle unit and in which the said valve and the said nozzle are connected by means of a suitable hose containing means for the generation of compressed air .
