Abstract
A nozzle component of the hand-held flaming gun consists of a hollow nozzle body (7). The nozzle component is characterized in that a joint (5) is embedded in the back-end lumen of the nozzle body (7) by a seal ring (6). The joint (5) has a filter element (4) and a nozzle (3), and a sleeve (1) is linked to the shoulder screw in the middle of the nozzle body (7). The firing end of the piezoelectric lead (10) matches the spout (9) of the nozzle body (7), a copper pipe (2) runs through the middle shoulder, the front shoulder and the tail should of the nozzle body (7). A first end of the copper pipe (2) on the tail shoulder is an admitting port which communicates with the intake cavity of the nozzle body (7), and a second end of the copper pipe (2) on the tail shoulder is vent port which communicates with the nozzle (3) through the filter element (4).
Description
Technical field
The utility model relates to the nozzle assembly of portable flame heater, relates in particular to the nozzle assembly of the hand flame gun that can cooperate the use of piezoelectric type ignition end.
Background technology
" the hand-held butane torch lamp " that disclose as Chinese utility model patent ZL00253263.8 is a kind of hand flame lamp of making fuel with the butane liquefied gas, it is made up of interior threeway lamp body and lamp socket and vapour storage tank, lamp body front end connection nozzle and radiating tube, fire-guide plate, the lamp body rear end is provided with needle valve switch, the lamp body lower end is connected on the lamp socket, and the thimble in the mat lamp body thrusts vapour storage tank the inner chamber of lamp body is communicated with vapour storage tank.It is outer through being nested with a tube connector that the lamp body front end connects nozzle, and be screwed, the tube connector front end radiating tube that is threaded, the radiating tube front end is provided with a fire-guide plate by sheath, sheath is fixed on the radiating tube with pin, and fire-guide plate is inlaid in the front end of radiating tube, has several through holes on the fire-guide plate.Nozzle assembly so, liquefied gas directly sprays, and because gas can not fully be vaporized, fuel value is lower usually, and flame takes on a red color, and pungent liquefied gas smell is arranged, and contaminated air wastes energy, the effect that influence is used.Especially can't cooperate piezoelectric type to get angry and hold use.Each use ignition trigger flame in advance could normally be used, and in the moment of igniting, if grasp improperly, very easily occurs dangerous.
Summary of the invention
Technical problem to be solved in the utility model is the present situation at prior art, provides a kind of gas that can make fully to vaporize, and can cooperate the nozzle assembly of the hand flame gun of piezoelectric type ignition end use.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: the nozzle assembly of hand flame gun, include the nozzle body of hollow, wherein: the nozzle body intracavity posterior end is embedded with joint through sealing ring, joint is fitted with filter core and nozzle, and nozzle body middle part convex shoulder is bolted with sleeve; The ignition end of piezoelectricity lead ends matches with the spout of nozzle body; The middle part convex shoulder of nozzle body, anterior convex shoulder and rear portion convex shoulder are penetrated with copper pipe; Copper pipe first end that is positioned at the rear portion convex shoulder is an air inlet, is communicated with the nozzle body inlet chamber, and copper pipe second end that is positioned at the rear portion convex shoulder is the gas outlet, is communicated with nozzle through filter core, and the distance so that prolongation gas is flowed through is so that reach the purpose of easier burning.
The measure of optimizing comprises: overheated in order to prevent nozzle body, damage the piezoelectricity lead-in wire, and the piezoelectricity lead-in wire runs through the middle part convex shoulder and the anterior convex shoulder of nozzle body, and is with earthenware on this section.
For reaching better and the equipped effect of valve assembly sealing, nozzle body cavity back segment is shaped on the round recess of placing the anaerobic adhesive sealing ring, and nozzle body cavity rear port also is shaped on the round recess that extends out.
For ease of heat radiation, guarantee long-time use, the nozzle body outer wall is shaped on louvre.
Compared with prior art, the utility model nozzle body intracavity posterior end is embedded with joint through sealing ring, and joint is fitted with filter core and nozzle, and nozzle body middle part convex shoulder is bolted with sleeve; The ignition end of piezoelectricity lead ends matches with the spout of nozzle body; The middle part convex shoulder of nozzle body, anterior convex shoulder and rear portion convex shoulder are penetrated with copper pipe; Copper pipe first end that is positioned at the rear portion convex shoulder is an air inlet, is communicated with the nozzle body inlet chamber, and copper pipe second end that is positioned at the rear portion convex shoulder is the gas outlet, is communicated with nozzle through filter core, and the distance so that prolongation gas is flowed through is so that reach the purpose of easier burning.Ignition process is that liquid gas is communicated with nozzle through nozzle body inlet chamber, copper pipe, filter core, and nozzle is ejected to the gas outlet, and the high-pressure electronic sparking of the ignition end output of piezoelectricity lead ends is than the gas that is easier to light abundant vaporization.It has unique gas that can make fully vaporizes, and the characteristics that can cooperate piezoelectric type ignition end to use.
Description of drawings
Fig. 1 is the utility model embodiment overall structure cross-sectional schematic;
Fig. 2 is the left lateral cross-sectional schematic of Fig. 1.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
To shown in Figure 2, the nozzle assembly of hand flame gun includes the nozzle body 7 of hollow as Fig. 1, and wherein: nozzle body 7 intracavity posterior ends are embedded with joint 5 through sealing ring 6, and joint 5 is fitted with filter core 4 and nozzle 3, and nozzle body 7 middle part convex shoulders are bolted with sleeve 1; The go between ignition end of 10 terminations of piezoelectricity matches with the spout 9 of nozzle body 7;
The middle part convex shoulder of nozzle body 7, anterior convex shoulder and rear portion convex shoulder are penetrated with copper pipe 2; Copper pipe 2 first ends that are positioned at the rear portion convex shoulder are air inlet, are communicated with nozzle body 7 inlet chambers, and copper pipe 2 second ends that are positioned at the rear portion convex shoulder are the gas outlet, are communicated with nozzle 3 through filter core 4, and the distance so that prolongation gas is flowed through is so that reach the purpose of easier burning.Be specially, ignition process is that liquid gas is communicated with nozzles 3 through nozzle body 7 inlet chambers, copper pipe 2, filter core 4, and nozzle 3 is ejected to gas outlet 9, and the go between high-pressure electronic sparking of ignition end output of 10 terminations of piezoelectricity is than the gas combustion that is easier to light abundant vaporization.It has unique gas that can make fully vaporizes, and the characteristics that can cooperate piezoelectric type ignition end to use.
Overheated in order to prevent nozzle body 7, damage piezoelectricity lead-in wire 10, piezoelectricity lead-in wire 10 runs through the middle part convex shoulder and the anterior convex shoulder of nozzle body 7, and is with earthenware 8 on this section.For reaching better and the equipped effect of valve assembly sealing, nozzle body 7 cavity back segments are shaped on the round recess 71 of placing the anaerobic adhesive sealing ring, and nozzle body 7 cavity rear ports also are shaped on the round recess 72 that extends out.For ease of heat radiation, guarantee long-time use, nozzle body 7 outer walls are shaped on louvre 73.
