Description
Technical field
The utility model relates to a kind of atomizer.
Background technology
Atomizer is a kind of can the atomization of liquid ejection, makes liquid in air, evenly be suspended in airborne device.Its operation principle is: liquid is through the internal pressure in any tank body or other devices; The liquid that it is inner squeezes in the shower nozzle; Swiftly flowing liquid is through shower nozzle outlet ejection; Atomizer is widely used in the various spray products, such as: pesticide, air aromatic, reagent spray, in the every field in the social life such as fire extinguisher equipment accessory.
For example; The patent No. is that the Chinese utility model patent of ZL200520002034.0 discloses a kind of fire extinguisher shower nozzle; Comprise the holder and the body of rod: the hollow on inclined-plane was horn-like in the holder front end became; Inner edge is provided with internal thread in the holder rear end: the body of rod is the hollow form that forms passage, and the lever front end outer peripheral face is around being provided with several spouts side by side, and is provided with several radial grooves corresponding respectively and that be communicated with several spray orifices in the front end inner edge: the body of rod is provided with first external screw thread and second external screw thread backward in regular turn by front end; The body of rod is locked on the internal thread of holder rear end with first external screw thread; And make lever front end by holder front openings emergence, though this fire extinguisher shower nozzle can increase to a certain extent extinguish material ejection uniformity, prevent turbulent flow, when fluid when the spout of this fire extinguisher shower nozzle sprays; Because the pressure in the tank body is steady relatively; Flow rate of liquid in the tank body is relatively slow, if when the thermal current of point of origin is big or point of origin when bigger thermal convection current is arranged, the extinguish material that this fire extinguisher shower nozzle sprays must receive the influence of thermal current, thermal convection current; Thereby cause the fire extinguishing effect of this fire extinguisher to be had a greatly reduced quality; The extraneous end of opposing interference performance is relatively poor, in addition the outer peripheral face of lever front end around the body of rod that is provided with several spouts side by side place the holder front end become in the hollow horn-like port on inclined-plane, though can be so that the atomizing effect of extinguish material is more remarkable; But the liquid flow velocity too loose, liquid that sprays from this fire extinguisher shower nozzle is lower, atomizer front end dropping liquid phenomenon is serious, is unfavorable for quick extinguishing.
For another example, the patent No. is that the Chinese utility model patent of ZL201120261401.4 discloses a kind of portable water mist fire extinguisher, comprises cylindrical shell, jet hose and shower nozzle; Said shower nozzle comprises housing, nozzle, atomizing core and sealing gasket, and an end of its middle shell is provided with cavity, and the other end is provided with the counterbore with internal thread that communicates with cavity; Counterbore connects said jet hose, and nozzle is arranged in the cavity, and nozzle interior is provided with several hollow cylindrical interior; The top of inner chamber is provided with spout, and the atomizing core is arranged in the inner chamber, is made up of core print seat and core body; The core road is track shape and is connected with the inner chamber inner thread, and core body is arranged on the core print seat and is cylindrical, and the core body top is provided with blind hole; Be provided with second conical surface that matches with first taper seat along the blind hole periphery, on this second conical surface, be provided with skewed slot, an end of skewed slot communicates with blind hole; The other end communicates with inner chamber, and sealing gasket is arranged between nozzle and the housing.Be provided with six skewed slots in this nozzle, though the water that gets in the blind hole rotate more easily, the raising centrifugal efficiency because of the limitation of its structure causes forming incrustation scale in the nozzle easily, influences the atomizing effect and the flow velocity of firing-fighting medium.To receive the influence of extinguishing chemical material bigger for this atomizer in addition, and the scope of application is narrower.
Summary of the invention

A kind of atomizer comprises joint, rotor, housing, and an end of said housing is a cylindrical outlet; The other end is a cylindrical cavity; The cylindrical cavity wall is provided with internal thread, and the cylindrical cavity bottom is provided with the cylindrical hole of three symmetries, and the line in three cylindrical hole axle center is an equilateral triangle; One end of cylindrical cavity bottom cylindrical hole is a cylindrical hole, and the other end of cylindrical cavity bottom cylindrical hole is a bellmouth.
Preferably, the cylindrical center of the bottom of said cylindrical outlet place is provided with boss.
Preferably, the bottom of said cylindrical outlet is provided with three cylindrical holes and is connected with the bellmouth perforation of the cylindrical cavity bottom cylindrical hole other end.
Preferably, the inner diameter of the cylindrical hole of said cylindrical cavity bottom cylindrical hole one end is greater than the diameter of rotor.
Preferably, the diameter of said rotor is greater than the diameter of the bottom cylindrical hole of cylindrical outlet.
Preferably, the diameter of said cylindrical outlet bottom cylindrical hole equals the bellmouth internal diameter of the cylindrical cavity bottom cylindrical hole other end.
Preferably, the two ends of said joint are respectively equipped with external screw thread, and the external screw thread of joint one end is connected with the internal thread of cylindrical cavity, and the other end of joint is connected with the outlet of fire extinguisher.
Preferably, said cylindrical center place at joint offers the jointing two ends and connects cylindrical hole.
Preferably, said rotor places in the cylindrical hole of three symmetries of cylindrical cavity bottom.
Preferably, the end place that is connected with the internal thread of cylindrical cavity of said joint is provided with two ladder cylinder shape grooves.
Preferably, said two ladder cylinder shape grooves are connected with joint two ends perforation cylindrical hole.
