Abstract

The utility model has a burner cap improved structure of gunjet. A muzzle, a spurt cap and a screw cap are orderly assembled at the front end of the gunjet. The end surface of the gunjet is arranged with an inner and outer circle flutes communicated with an air outlet, and the surrounding edge of the inner circle flute forms a ring pyramidal face. A taper tube of the muzzle is arranged by screws behind the screw thread of the gunjet. The pyramidal face of the taper tube is sealed on the ring pyramidal face of the gunjet, which makes the outer ring wall of the ring body and the outer ring wall of the gunjet outer circle flute have a clearance. The other end of the ring body is provided with a top pyramidal face for sealing the hollow tube top tapering portion of the spurt cap. The top tapering portion extends inwards to form a ring flange, and the space between the ring flange and the muzzle's outer ring wall is proper. Therefore, the number of the fitting parts can be reduced, and the manufacturing cost can be reduced. The utility model is not only convenient for installation, but also has the effect of voltage stabilization and leak prevention.

Description

The shower nozzle structure-improved of spray gun

Technical field

This creation relates to a kind of spray gun, particularly relates to a kind of shower nozzle structure-improved of spray gun.

Background technology

The general at present shower nozzle product that occurs on the market all designs more superior, for various demand, consider its steady air current of giving vent to anger, requirement uniformly simultaneously, usually the interchannel that can pass through at gases at high pressure is provided with structure of voltage regulation, to relax gases at high pressure in the process of giving vent to anger, directly scurry out nozzle and have influence on the carrying out of spraying operation; In " the lance head structure of replaceable nozzle " a case, see also Fig. 1, Fig. 2, it is at spray gun 91 front ends winding in regular turn one seal ring piece 92, one spiral shell knot seat 93, one nozzle 94 and a shower nozzle 95, one nut 96, wherein, the spray gun 91 heads end face central authorities of giving vent to anger stretch out the passage leading portion of regulating shank 911 and form screw and be spirally connected for spiral shell knot seat 93, described end face and 93 of spiral shell knot seats are also established into seal ring piece 92, its end face and spiral shell knot seat 93 forward surfaces respectively form involutory in, inner annular recess 912,913,931,932, and the seal ring piece 92 corresponding circular row slotted eyes 921 that form, in the spray gun 91, inner annular recess 912, in 913 and respectively establish the duct 914 of giving vent to anger, and spiral shell knot seat 93 is established several ventholes 9321 and is worn the groove space that is separated out with flange 9322 to front end face one in inner annular recess 932, and form the circular row groove 934 that an outer ring edge is a pushing face-drawing 9341 around at the relative hollow screwed pipe 933 in spiral shell knot seat 93 front sides, and the passage in the outer annular recess 931 9311 is drilled into the ring wall of circular row groove 934 and communicates.In addition, its nozzle 94 is that the spiral shell knot is at spiral shell knot seat 93 front ends, extend to corresponding circular row groove 934 inner edges and form a ring slice 941 in its external rings side, and shower nozzle 95 is inner to be stretched the circular depressed 951 of putting for nozzles 94 and pushes away in its ora terminalis ring side moulding one and pull out ring body 9511, pulls out the pushing face-drawing 9341 that ring body 9511 is docked at spiral shell knot seat 93 circular row grooves 934 and make to push away; It is to utilize ring slice 941 to stop 9311 airflow flowing of passage of being tied seat 93 outer annular recess 931 by spiral shell, flange 9322 stops 9321 airflow flowing of venthole by spiral shell knot seat 93 inner annular recess 932, make gases at high pressure by ring slice 941 and shower nozzle 95 interior ring-side walls again, and the slit that is produced between ring-side walls in flange 9322 and the nut 96 gives vent to anger, and reaches the effect of voltage stabilizing.

Above-mentioned lance head constitutional detail is numerous, not only number of assembling steps becomes many, and can make the cost of finished parts improve, moreover its script purpose of design is except voltage regulation result, also can be used to replace different nozzles in addition, change its spray cap with respect to nozzle and also might and then change, must make more polygamous part on the contrary, so be necessary to be improved.

This case creator has the deficiency of stating lance head structure commonly used in view of this, study intensively, and the accumulation individual is engaged in the many years of experience of this cause, design a kind of shower nozzle structure-improved of brand-new spray gun eventually, its number of spare parts is few, be convenient to assembling, and can reduce the cost of making part, and the improvement of this creation can take into account the effect of voltage stabilizing and leakproof simultaneously.

Summary of the invention

The purpose of this creation is, the few lance configuration of a kind of number of spare parts is provided and can have reduced the cost of making part, and it not only is convenient to assembling, and takes into account the effect of voltage stabilizing and leakproof.

For reaching above-mentioned purpose, the shower nozzle structure-improved of this creation spray gun, it is with a nozzle, spray cap and nut are assembled in the spray gun front end in regular turn, and the spray gun end face be provided with communicate with the duct of giving vent to anger in, inner annular recess, and the outer annular recess periphery is to be circular cone, wherein, described nozzle one end is a conical pipe portion, the other end is the nozzle tip pipe, and its conical pipe portion ring bodies that stretches out, and described ring bodies one end face is that corresponding spray gun circular cone forms the conical surface, offer the cannelure of corresponding outer annular recess on its conical surface, therefore, after described nozzle conical pipe portion is arranged in the threaded portion of spray gun, the conical surface of conical pipe portion is connected airtight on the circular cone of spray gun outer annular recess, and the cannelure on the conical surface just is communicated with the outer annular recess formation of spray gun, and between the peripheral ring wall of ring bodies outside ring wall and spray gun inner annular recess, has appropriate gap; In addition, in cannelure, offer the passage that several are communicated to the ring bodies other end, and be provided with in the ring bodies other end for the addendum cone face that connects airtight spray cap hollow tube addendum cone portion, have appropriate gap between ring wall outside and the addendum cone portion ring flange that extends internally, described ring flange and nozzle.

According to above-mentioned structure, it is the threaded portion that directly nozzle is arranged in spray gun inside, the conical surface of nozzle conical pipe portion can be connected airtight on the circular cone of spray gun outer annular recess periphery, in the time of will spraying cap again and establish the threaded portion that is fixed on spray gun outside ring wall with the nut spiral shell, the addendum cone portion of spray cap hollow tube opening outer rim is connected airtight on the addendum cone face of nozzle, therefore, except leak-stopping glue ring, three major parts are only arranged, it not only is easy to assembling, and reduced thereby reduced the cost of making part because of number of spare parts, because the addendum cone portion of spray cap is the addendum cone face with nozzle is after connecting airtight mutually, in it, just do not have the problem of gas leakage between exterior air drain, and in making, the gas that flows in the exterior air drain can the phase mutual interference; In addition, the ring flange of spray cap be and nozzle outside ring wall between the gap, and the gap between the peripheral ring wall of the ring bodies of nozzle outside ring wall and spray gun inner annular recess, form the structure of voltage regulation of inside and outside air flue respectively, make gas when inside and outside air flue flows, can be hindered afterwards earlier and be concentrated, spray equably by above-mentioned gap again, and make that the gas pressure of its ejection is more stable.

As mentioned above, adopt the utility model of technique scheme, it is lower, easy to assembly and take into account the advantage of voltage stabilizing and leakproof to have a cost.
