Description

Foam gun

Technical field

The present invention relates to make the foam gun of foam gap filler ejection and foaming.

Background technology

About the door in building and the house, window, body of wall, coating, mix earth, water-impervious such as timber and frosting is installed, joint filling or mending-leakage, the insulation that air-conditioning is installed, application of anti-leakage layers, various pipelines are installed, fill in the surplus hole of ventilating opening and electric wire outlet, combined socket and switch and the relevant installation that needs insulation etc., generally all adopting foam gap filler is raw material, such as: foam gap filler can adopt and comprise gas and the chemical raw material that self has air pressure, comprise butane gas and urethane raw etc. such as employing, ejection post-foaming＜expansion〉and form foam-like, spontaneous curing and form porous or spongiform joint filling thing (filler) is bonded in needed place again, during use, by foam gun foam gap filler is discharged and reach installation, joint filling, mending-leakage, insulation, insulation or purpose such as bonding, foam gap filler is generally in the foam gun internal channel and self has air pressure or than the liquid state of hyperbar, when opening liquid valve by switching device, expand and solidify and be bonded in needed place in the foam gap filler that ejects foaming back, in order to adapt to the construction of different places or diverse location, drain pipe is generally long structure, the length that the length of drain pipe surpasses the rifle body is preferable selection, such as, it is preferred more than 150 millimeters that the length of drain pipe surpasses, but, long drain pipe exists the defective of following several respects: 1, when adopting iron pipe or copper pipe or aluminum pipe, because iron material or copper product or aluminum are easy to oxidation or are corroded and make foam gun the phenomenon of leakage occur easily; The color of joint filling thing is polluted in residual thing or corrosion easily, has influenced the quality of construction; The surface of longer drain pipe is easy to occur large-area rust staining or oxidation spot, make the surface become coarse and dirty, it is good especially that foam gap filler is bonded on rust staining or the oxidation spot fastness, very difficult cleaning maybe can't be cleared up and be made surperficial thickening, cause drain pipe to be difficult to put in the less slit and construct, cause constructional difficulties maybe can't construct; If adopt thin material, insufficient strength is easy to occur distortion or damaged and cause the phenomenon of leakage; If adopt thicker or bigger material, cost is very high, has wasted resource, and the volume of drain pipe is increased, and is difficult to be adapted at constructing in the less slit, and uses heavy.2, when drain pipe adopts plastic tube, the tube wall of longer plastic tube is easy to occur pore (micropore) or stream seam and cause leakage or foam gun passage clogging to occur man-hour adding, service life is short, simultaneously, insufficient strength, long drain pipe is easy to occur breakage or crack to be made the foam gap filler ejection and is bonded on one's body or is difficult to clean on the clothing or on the article, even can't clean, be bonded at accidentally on the eyes and can cause serious consequence, even the danger of burning or exploding also can appear, in addition, residual foam gap filler generally all adopts cleaning agent to clean in the plastic tube of use post-foaming rifle, and cleaning agent is easy to corrode plastics and the phenomenon of leakage occurs.
