Abstract

The utility model relates to a portable static electricity paint sprayer which is composed of a spray paint head and a high voltage generator, which is characterized in that the upper part of the gun type spray paint head is provided with an interface which is in threaded connection with a paint storing bucket. A drum hollow cavity of the front end opening is provided with a hollow stem of a metal swing cup, the hollow stem penetrates through the body wall of the spray paint head and is connected with one end of an insulated coupled axle via a connector, and the other end of the connector is connected with a motor which is arranged in the cavity. A valve core which can control the paint flow capacity is arranged in the upper part of the hollow stem of the metal swing cup, a spring is sheathed on the valve core, and a sleeve is screwed on the spring. The valve core is also sheathed with a deflector rod which is controlled by a trigger, and a high voltage negative pole of a high voltage generator is added to the metal swing cup via a conducting wire and an elastic trip.

Description

Portable static electricity paint sprayer

The utility model relates to a kind of portable electrostatic air painter.

Existing electrostatic painting device is because of due to its structure, and not only volume is big, Heavy Weight, and operation effort, poor performance.

The purpose of this utility model be design a kind of rational in infrastructure, easy to use, volume is small and exquisite, the portable electrostatic air painter of excellent performance, alleviating operator's labour intensity, improves the paint spraying quality.

The utility model by pistol type spray paint the head and high pressure generator two parts form, the paint that its pistol type sprays paint in the paint storage barrel on the head is gone into getting rid of in the cup by the driven by motor rotation through adding the lacquer orifice flow under the gravity effect, and under action of centrifugal force, form very thin paint film and from get rid of cup, eject; Owing to adopt high-frequency generator, stepup transformer, the high voltage negative of the high pressure generator that voltage-doubler rectifier constitutes reaches and is connected on metal and gets rid of on the cup, therefore, the paint that ejects from get rid of cup also has the high pressure negative electricity, and electronegative lacquer grain is further atomizing aloft under the like charges repulsive interaction, simultaneously, because waiting to coat with lacquer thing joins with ground, therefore, wait to coat with lacquer thing and the head that sprays paint gets rid of and also formed high voltage electric field between the cup, make electronegative lacquer under this electric field action, uniform settlement is waiting to coat with lacquer the thing surface, thereby finishes painting process.

Below in conjunction with accompanying drawing the utility model is elaborated:

Fig. 1 is the structural representation of the head that sprays paint in the utility model;

Fig. 2 is the electrical schematic diagram of the utility model mesohigh generator.

Referring to accompanying drawing 1, spray paint head by getting rid of cup 1, paint storage barrel 2, a body 3 sprays paint, spring 4, sleeve 5,19,23, spool 6, driving lever 8, connector 9,17 motors 10, connecting shaft 11, handle 12, lead 13, plate machine 14, shell fragment 18, oil sealing 20,22 constitute, be installed with paint storage barrel 2 in the described set hickey in a body 3 tops that sprays paint, front opening garden tube cavity central authorities have the through hole that is communicated with hickey and inner chamber that runs through body wall, in the tube cavity side opening of opening garden, be provided with oil sealing 22, and be installed with sleeve 23, in the inner chamber side opening, also be provided with oil sealing 20, and be installed with sleeve 19, place the hollow stem that gets rid of cup 1 of opening garden tube cavity to pass through sleeve 23, oil sealing 22, hickey and oil sealing 20, sleeve 19 is connected by connector 17 with an end of connecting shaft 11, the motor 10 that is arranged in the inner chamber is connected by connector 9 with the other end of connecting shaft 11, add lacquer hole 21 getting rid of on cup 1 the hollow stem to have corresponding to the hickey position, above intracavity sidewall upper bush 19, also have the hole that is communicated with hickey, spool 6 is housed in the hole, on spool 6, be set with spring 4, on spring 4, be installed with sleeve 5, by bearing pin 15 fixing can outside plate machine 14 1 ends that it freely rotates, being exposed at outside the head's body 3 that sprays paint, the other end with connect by fixing can the reaching of bearing pin 16 around an end of its driving lever that freely rotates 8, the other end of driving lever 8 is sleeved on the spool 6, and by wing nut 7 lockings, shell fragment 18 is fixed on the body sidewall of the body 3 that sprays paint, the one end contacts with the hollow stem that gets rid of cup 1, the other end is connected with the high voltage negative of high pressure generator by lead 13, motor 10 also is connected with high pressure generator by lead 13, and handle 12 is equipped with in the bottom of the body 3 that sprays paint.

In the utility model spray paint head except that get rid of cup 1, cover spring 4, spool 6, motor 10, shell fragment 18, sleeve 19,23, all adopt the high-strength insulating material manufacturing.

Referring to accompanying drawing 2, high pressure generator is made of high-frequency generator, stepup transformer and voltage-doubler rectifier, and its high-frequency generator adopts NE555 integrated package and resistance R ₁R ₂, R ₃, capacitor C ₂, C ₃, C ₅Zener diode D ₅Form, stepup transformer adopts capacitor C ₄Transformer B ₁, B ₂, FET BG ₁, BG ₂Form, voltage-doubler rectifier adopts capacitor C ₆-C _n, diode D ₆-D _nForm, its operation principle is: civil power is through diode D ₁-D ₄, capacitor C ₁Be divided into three the tunnel behind the rectifying and wave-filtering, the first via is for motor in the head that sprays paint; The second the tunnel through resistance R ₁, Zener diode D ₅For the high-frequency generator of forming by NE555 etc., make it vibration and export high frequency square wave after the step-down, pass through capacitor C ₄With transformer B ₁Add to FET BG ₁, BG ₂Grid; Third Road adds to step-up transformer B ₂On the centre cap of first siding ring, also make step-up transformer B ₂Second siding ring on produce ac high-voltage, pass through number utmost point voltage-doubler rectifier again, rectification goes out up to a hundred kilovolts high direct voltage.The positive high voltage utmost point of high pressure generator and ground short circuit, the negative high voltage utmost point adds to metal by lead and shell fragment and gets rid of on the cup.

The utility model need only be loaded onto paint storage barrel in use, with the high pressure generator back of the body piggyback, with holding the head that sprays paint surely, aims at and waits to coat with lacquer thing and keep certain distance, turns on the power switch, and pulls the machine of dialling and gets final product.

The utility model compact conformation, rationally distributed, volume is small and exquisite, easy to use, and spraying property is good, uses when being suitable for generally spraying paint.
