Abstract

The utility model provides a handheld gun-shaped electrostatic eliminator. The electrostatic eliminator comprises an air supply device including a manual valve connected with a connection pipe at one end, wherein a speed control valve is arranged on the connection pipe; an action point is arranged on the manual valve and on the same side of a concave holding space of a gun-shaped main body with respect to the action potion of a power switch of a high-voltage control device; and an adjusting screw rod is arranged on the speed control valve for limiting the flow rate of air, such that the proportion of outlet flow rates can be adjusted by an operator at any time. Accordingly, the workpiece is prevented from being blown away due to high air pressure, and the high-voltage cable is prevented form being exposed to the outside due to high pressure.

Description

Handheld gun type Xelminator

Technical field

The utility model relates to a kind of Xelminator, particularly relates to a kind of handheld gun type Xelminator.

Background technology

See also shown in Figure 1, eliminate spray gun by general traditional hand-held electrostatic, by establishing a hand-operated valve 31 in the rifle type body 3, described hand-operated valve 31 is pressed transfer tube 11 and air compressor machine 1 to connect with air and is established, high voltage source supply 2 then transfers to rifle type body by high voltage transmission cable 21 with external high-tension electricity, and its shortcoming is as follows:

1, the air pressure size is not easy control:

Described general traditional static is eliminated spray gun, the size of its air mass flow is to press by switch handle 32 to touch hand-operated valve 31, when the operator applies switch handle 32 strength when big, then the angle of hand-operated valve 31 unlatchings is big, the air capacity of ejection is just big, if the strength that operator's hand applies is little, then the angle of hand-operated valve 31 unlatchings is little, the air capacity of ejection is just little, also thereby the discharge rate size that makes described general traditional static eliminate its air pressure of spray gun can't quantitatively control;

And because static is eliminated the major function of spray gun, be to utilize air compressor machine 1 air pressure that produces and the ion that cooperates the interior spray point corona discharge of rifle type body to produce, be sprayed onto workpiece together and be stained with sticking dust with elimination static and its, yet, the quite big (about 7～10kgf/cm of the air pressure that common air compressor machine 1 produces ²), therefore the operator need control the size of hand-operated valve 31 opening angles, produce suitable air pressure ejection, but, if too greatly then air pressure output is then excessive for opening angle, thereby cause described workpiece to be blown away or blow askew situation taking place, but if opening angle is too little, it is too little again then can to produce air pressure output, then can cause described workpiece to blow sordid situation again produces, it is all because the air pressure that air compressor machine 1 produces is quite big, makes that the operator is often wayward to exert oneself, and makes the air pressure can the quantitatively output according to expection;

2, the start and stop of corona discharge control is easy to generate problem:

Traditional static is eliminated spray gun, its high voltage source supply 2 is a separate type with rifle type body 3, be by a high voltage transmission cable 21, the high-tension electricity of high voltage source supply 2 is sent in the rifle type body 3, and this high voltage transmission cable 21 have high-tension electricity (about 5～7KV) because outside it is exposed to, therefore in case described high voltage transmission cable 21 impaired broken skins, very likely cause personnel or equipment to be subjected to the danger of high-voltage electric shock, even cause fire;

In addition because high voltage source supply 2 is to separate to be arranged on outside distant place, therefore the start and stop of described high voltage source supply 2 need the operator to go to high voltage source supply 2 places and come switch, therefore quite inconvenience, in a single day and forget and close high voltage source, then also might cause danger.

Summary of the invention

The purpose of this utility model is: a kind of handheld gun type Xelminator is provided, reaches and comply with expection adjustment, quantitative delivery air pressure and can get rid of the purpose that high-voltage line exposes.

For achieving the above object, the technical solution adopted in the utility model is:

A kind of handheld gun type Xelminator, it comprises:

One air pressure feeding mechanism, described air pressure supply installing is equipped with a hand-operated valve, described hand-operated valve one termination is established a tube connector, described tube connector connects establishes a governing valve, described hand-operated valve is provided with an application point, and the application point of its application point and its mains switch of high voltage control unit is with accommodation space one side that is located at rifle type body indent, and described again governing valve is provided with an adjusting screw(rod); Rely on adjusting screw(rod) limit air flow, allow the operator can adjust the ratio of rate of discharge at any time, and then reach and to prevent to be full of the deficiency that high pressure exposes with preventing the external cable of high pressure because of making air pressure cause workpiece to be blown away too greatly or blowing askew deficiency.

The utility model advantage:

1. can make air pressure comply with expection adjustment, quantitatively output.

2. can avoid workpiece to be blown away, blow the askew deficiency that maybe can't blow off is got rid of.

3. can get rid of high-voltage line exposes.

4. easy and simple to handle.
