Abstract
The invention discloses a spring gun for an electrostatic atomizer, which comprises a gun handle, a spray rod and a spray nozzle, which are connected in turn. The spray gun is characterized in that: the gun handle is covered by a conductive sleeve; the tail part of the gun handle is provided with a metal hose covered by an insulation material through a metal embedding piece; and one end of the metal hose is connected with the conductive sleeve through the metal embedding piece and the other end of the metal hose is connected with the positive pole of a high-voltage electrostatic generator of the electrostatic atomizer. When used by an operator, the spray gun can effectively transfer the potential of the positive pole of the high-voltage electrostatic generator to the ground, offer a comfortable handfeel and protect the operator against a high-voltage electric shock danger.
Description
Technical field
The present invention relates to electrostatic atomiser, especially the spray gun of electrostatic atomiser.
Background technology
When electrostatic atomiser is made the heavy-smoke type spray, utilize high-pressure electrostatic to form a high-voltage electrostatic field, liquid atomizes through shower nozzle and fills with electric charge, and under the effect of electrostatic field, droplet is adsorbed on the target do directed movement, thereby improves the calm rate of droplet group on target.
In the prior art, one of them electrode (negative pole) that is positioned at the HV generator on the electrostatic atomiser makes the liquid droplet with electric charge, another electrode (positive pole) is wired on the spray gun pikestaff, metal insert on the spray gun pikestaff is delivered to the earth by human body, make the earth and on attachment form another utmost point position of high-voltage electrostatic field, during spray, with the medicine of electric charge drip will be adsorbed on above.
Yet at present the common practice of this area is: be embedded with bonding jumper at pikestaff, be connected to the positive pole (earth terminal) of electrostatic sprayer HV generator by a resistance that is through wire in the plastic flexible pipe and a high value; The user is owing to the metal insert that can not hold reliably on the pikestaff, in operating process, often suffer high-voltage electric shock, contact with the effective of high pressure generator if can not guarantee human body, electrostatic efficiency is undesirable in the time of will causing operation, and traditional spray gun of sprayer feel is relatively poor in use.
Summary of the invention
The present invention seeks to: for the deficiencies in the prior art, a kind of spray gun of electrostatic atomiser is provided, it can be delivered to the earth effectively with the positive electrode potential of HV generator when operating personnel use, and comfortable feel, can avoid operating personnel to suffer the danger of high-voltage electric shock.
Technical scheme of the present invention is: a kind of spray gun of electrostatic atomiser, comprise the pikestaff, spray boom and the shower nozzle that link to each other successively, it is characterized in that: described pikestaff is coated with conductive sleeve, and the pikestaff afterbody is equipped with a metal hose that is coated by insulating materials by metal insert; One end of this metal hose links to each other with conductive sleeve by described metal insert, and the other end links to each other with the positive pole of the HV generator of electrostatic atomiser.
Described conductive sleeve is made by conductive rubber.
Described metal insert is copper insert.
Described metal hose is stainless steel flexible hose.
Described metal insert by be fixed on columnar body, the nut that is threaded with body on the pikestaff and be stuck in body and nut between packing ring consist of, described metal hose is stuck in this metal insert by the gun barrel coupling nut that its end arranges.
Be threaded between described shower nozzle and the spray boom, be connected by nipple between described spray boom and the pikestaff.
Advantage of the present invention is: the present invention coats one deck conductive sleeve at the pikestaff of spray gun, this conductive sleeve links to each other with the HV generator of electrostatic atomiser is anodal by metal insert and metal hose, as long as holding pikestaff, the user just the positive electrode potential of HV generator can be delivered to the earth effectively, the danger of also having avoided operating personnel to be clicked when conductive stability is high, and this spray gun comfortable feel, easy to operate.
Description of drawings
Fig. 1 is the structural representation (cutaway view) of the embodiment of the invention;
Fig. 2 is the A section enlarged drawing of Fig. 1;
Fig. 3 is the B section enlarged drawing of Fig. 1.
The specific embodiment
Fig. 1 ~ Fig. 3 has shown a specific embodiment of electrostatic atomiser spray gun of the present invention, and it comprises pikestaff 1, spray boom 2 and the shower nozzle 3 that links to each other successively; Wherein be threaded between shower nozzle 3 and the spray boom 2, between spray boom 2 and the pikestaff 1 by nipple 7 be connected (as shown in Figure 3).
As depicted in figs. 1 and 2, this example is surrounded by one deck conductive sleeve 4 outside pikestaff 1, and this conductive sleeve 4 adopts the conductive rubber with certain resistivity to make.By metal insert 6 metal hose 5 that is coated by insulating materials is installed at pikestaff 1 afterbody, one end of this metal hose 5 links to each other with conductive sleeve 4 by metal insert 6, the other end links to each other with the positive pole (being earth terminal) of the HV generator (not shown) of electrostatic atomiser, thereby conductive sleeve 4 is communicated with the positive pole of HV generator, in a single day the user holds pikestaff 1 and has just touched conductive sleeve 4, carries out the positive electrode potential of HV generator is delivered to the earth effectively.As preferably, above-mentioned metal insert 6 is generally copper insert, and metal hose 5 is generally stainless steel flexible hose.
Reference numeral 8 expression drug liquid tubes (being O shape flexible pipe) among Fig. 1, this drug liquid tube 8 is positioned at metal hose 5, an end of drug liquid tube 8 by membrane pump be connected with the liquid storage container (not shown) of electrostatic atomiser, the other end be connected with the medicine liquid channel of spray gun inside (conventional structure).In fact, metal hose 5 has not only played the effect that is communicated with HV generator positive pole and conductive sleeve 4, also has the function (all be to adopt plastic flexible pipe to protect drug liquid tube in the past, and ruptured easily) of protection drug liquid tube 8.
As shown in Figure 2, above-mentioned metal insert 6 by be fixed on columnar body 6-1, the nut 6-2 that is threaded with body on the pikestaff 1 and be stuck in body and nut between packing ring 6-3 consist of, described metal hose 5 is stuck in this metal insert 6 by the gun barrel coupling nut 5-1 that its end arranges.
Certainly, above-described embodiment only is explanation technical conceive of the present invention and characteristics, and its purpose is to allow people can understand content of the present invention and implements according to this, can not limit protection scope of the present invention with this.The all Spirit Essence of main technical schemes is done according to the present invention equivalent transformation or modification all should be encompassed within protection scope of the present invention.
