Description

The sprinkler configuration of Spray painting tool

Technical field

The utility model relates to a kind of sprinkler configuration of Spray painting tool, especially the improvement of the atomization gas pore structure in the shower nozzle of a kind of paint sprayer of finger, it is utilize to be provided with more and more to concentrate on atomizing pore around the center of orifices, to reach the effect of being convenient to sucking-off and atomizing paint.

Background technology

The structure of existing Spray painting tool (spray gun), as Fig. 4～shown in Figure 6, it is mainly constructed and includes a spray gun body 40, form with spray cap 44 with the air guide ring 41 that is arranged on spray gun body 40 front ends, nozzle 42, shower nozzle 43, wherein said air guide ring 41 and nozzle 42 are to lock in regular turn the front end of the paint vehicle pipeline 401 of spray gun body 40 (again, described air guide ring 41 and the structure of nozzle 42 also can be combined into the form of same part); Described shower nozzle 43 is provided with several atomizing pores 431, typing pore 432 and a center of orifices 433, relies on spray cap 44 that it is locked on the air guide ring 41 of described spray gun body 40 front ends; Air duct 402 more than being provided with together again around the described paint vehicle pipeline 401, and can be by the guiding of air guide ring 41 with the pore of shower nozzle 43, to provide the paint raw materials of sucking-off in paint vehicle pipeline 401 required gas.

As above-mentioned existing structure, wherein be located at atomizing pore 431 on the shower nozzle and generally be typing pore 432 extension line settings, and generally have only (as Fig. 5) about 2 to 4 along center of orifices 433 both sides; During enforcement, be to utilize the outwards gases at high pressure of ejection of described center of orifices 433, make nozzle 42 head ends form vacuum state, rely on the vacuum attraction principle with will be in the paint sucking-off in the paint vehicle pipeline 401, impact the paint vehicle that is sucked out by the gas of atomizing pore 431 ejection again and do the preliminary atomizing of breaing up, then the air that intersects ejection by the symmetrically arranged setting pore 432 in the outside paint vehicle that will be atomized is made secondary-atomizing and is sprayed on the painting object, and spraying face is shaped to the shape (as Fig. 6) that is oblong a.Yet, because it is more and more strict to paint vehicle now in response to the demand of environmental protection, the use that is required to use natural material and minimizing interpolation organic solvent (as: toluene ...) that it is tried one's best is difficult for sending forth so the more general existing coating of present environment-friendly type coating is denseer, thicker; Therefore according to above-mentioned existing nozzle structure be can't be effectively with the sucking-off smoothly of denseer thick paint vehicle with break up atomizing, cause easily causing feed to have some setbacks and be sprayed onto the phenomenon that body surface has the coating inequality, so to described existing necessity that improves again that is configured with.

This case utility model designer is because the design of the nozzle structure of above-mentioned existing Spray painting tool and effectively sucking-off is just and break up the disappearance of atomizing to comparatively dense thick material of paint now, the whence studies intensively, and long-pending individual is engaged in the many years of experience of described cause, designs a kind of sprinkler configuration of brand-new Spray painting tool eventually.

Summary of the invention

At the deficiencies in the prior art, the purpose of this utility model is: the sprinkler configuration that a kind of Spray painting tool is provided, it is center of orifices periphery at described shower nozzle, difference according to the paint density, and symmetry be equipped with more, more intensive atomizing pore, with can be effectively with the paint vehicle sucking-off with make its atomizing.

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

A kind of sprinkler configuration of Spray painting tool includes a spray gun body, is arranged on air guide ring, nozzle, shower nozzle and the spray cap of spray gun body front end, and wherein said air guide ring and nozzle are the front ends at the paint vehicle pipeline of spray gun body of locking in regular turn; Described shower nozzle is provided with several atomizing pores, typing pore and a center of orifices, is by the spray cap it to be locked on the air guide ring of described spray gun body front end, the air duct more than described paint vehicle pipeline is provided with together on every side again; It is characterized in that:

Atomizing pore on the described shower nozzle has more than 10, and is the both sides that symmetrical ring is located at center of orifices.

Compared with prior art, adopt the advantage that the utlity model has of technique scheme to be:

When using, several atomizing pores have been provided with owing to wherein around the center of orifices of shower nozzle, concentrate, to promote the impulsive force and the angle of attack of its atomizing paint vehicle according to above-mentioned tectonic association; Therefore, nozzle structure of the present utility model can be effectively with denseer thick paint vehicle sucking-off with break up atomizing.

The specific embodiment

For making your juror further understanding and understanding be arranged, lift a possible embodiments now and cooperate graphic being described in detail as follows structure of the present utility model, device and feature thereof:

At first see also shown in Fig. 1, Fig. 2, Fig. 3 A～Fig. 3 C, the sprinkler configuration of Spray painting tool of the present utility model, main structure includes a spray gun body 10, form with spray cap 14 with the air guide ring 11 that is arranged on spray gun body 10 front ends, nozzle 12, shower nozzle 13, wherein said air guide ring 11 and nozzle 12 are the front ends (again, described air guide ring 11 is implemented with the form that the structure of nozzle 12 also can be changed into same part) at the paint vehicle pipeline of spray gun body 10 of locking in regular turn; Described shower nozzle 13 is provided with several atomizing pores 131, typing pore 132 and a center of orifices 133, is to rely on spray cap 14 that described shower nozzle 13 is locked on the air guide ring 11 of described spray gun body 10 front ends; Air duct more than around described paint vehicle pipeline, being provided with together again, and can paint required gas so that sucking-off to be provided by the air guide ring 11 and the guiding of the pore of shower nozzle 13; It is characterized in that: the atomizing pore 131 on the described shower nozzle 13 has more than 10, and is the ring of the symmetry both sides that are located at center of orifices 133 (promptly in center of orifices 133 to typing pore 132 extension line directions).The atomizing pore 131 of above-mentioned shower nozzle the position is set, spread geometry that can be shown in Fig. 3 A to Fig. 3 C during enforcement is the periphery that majority concentrates on center of orifices 133.

When using according to above-mentioned tectonic association, owing to wherein be arranged on around the described center of orifices 133 most the concentrating of the atomizing pore 131 of shower nozzle, causing to have most the powerful gas columns as needle-like simultaneously, impact the described paint vehicle that just has been sucked out simultaneously with different angle directions, also helping and forming nozzle 12 front ends is true control state, the paint vehicle that is sucked out is taken away also can keep oblong spraying face; Therefore, shower nozzle 13 structures of the present utility model promote its ability of hitting paint vehicle, and effectively will denseer thick paint vehicle sucking-off and the purpose of breaing up atomizing.

More than explanation is just illustrative for the utility model, and it is nonrestrictive, those of ordinary skills understand, under the situation of the spirit and scope that do not break away from claim and limited, can make many modifications, variation or equivalence, but but all will fall within the claim restricted portion of the present utility model.
