Abstract
The utility model relates to a hot air gun, in particular to a high-temperature hot air gun which comprises a shell assembly, a spiral ceramic framework, an electric heating wire and a cap. The shell assembly comprises a stainless steel inner shell, a heat-preserving layer and an outer shell. The heat-preserving layer is a ceramic fiber plate; the spiral ceramic framework is arranged in the shell assembly; the electric heating wire is connected with the spiral ceramic framework in a wound mode; the cap is in threaded connection with the front end of the outer shell and is sealed and fixed. The heat-preserving layer is additionally arranged outside the spiral ceramic framework, so that most of heat can flow out along with hot air from an air outlet nozzle, utilization efficiency is improved, the effect of saving energy is achieved, use is safer, and the service life is greatly prolonged.
Description
Technical field
The utility model relates to a kind of heat gun, espespecially a kind of high-temperature hot-air rifle.
Background technology
Heat gun is by fan by air intake suction nozzle, and then air enters the space of porous ceramic skeleton, after heating wire is heated, discharges high-temperature hot air by outlet nozzle; Heat gun is generally used for the industries such as pvc pipe packaging, scalds for the envelope of the outer winding plastic film of pvc pipe.
And existing heat gun, because the suction nozzle cross section of heat gun is less, the cross section of ceramic skeleton is larger, bone porous space is more, cold air can not flow through from each space uniformly, cause the air mass flow in each space different, but resistance wire is certain at the power in each space, the heat in each space is certain; In the time that flow is different, the space internal resistance wire temperature drift that flow is little, so just easily causes heating wire easily to blow, and while causing work, the life-span is shorter.
And because heat gun porous ceramic skeleton does not adopt Insulation outward, after the heat that heating wire sends is transmitted on shell by ceramic skeleton, heat gun skin temperature is higher, causes workplace dangerous, and waste energy.
Summary of the invention
For the deficiencies in the prior art, it is longer that the utility model aims to provide a kind of life-span, the high-temperature hot-air rifle that safety coefficient is higher.
In order to address the above problem, the utility model provides following technical scheme:
A kind of high-temperature hot-air rifle, comprises
Housing unit, described housing unit comprises stainless steel inner casing, heat-insulation layer and shell, described heat-insulation layer is ceramic beaverboard;
Spiral ceramic skeleton, described spiral ceramic skeleton is arranged in housing unit; And
Heating wire, described heating wire is wire-wrapped on described spiral ceramic skeleton;
Block, the front end of described block and described shell is spirally connected to seal and fixes.
Described heat-insulation layer is located at the skin of described stainless steel inner casing, and described shell is located at the skin of described heat-insulation layer.
Described shell is located at the skin of described stainless steel inner casing, and described heat-insulation layer is located at the skin of described shell.
One-body molded on described block have a suction nozzle.
On described block, be provided with a tooth screw, porcelain head, nut, a described tooth screw is fixedly screwed onto on described block, described porcelain head socket is arranged on a described tooth screw and fixes by described nut, makes described porcelain head withstand described block.
The rear end of described shell is provided with outlet nozzle, and described outlet nozzle is horizontal funnel type outlet nozzle, and described outlet nozzle is provided with thermometric seat, and described outlet nozzle and described shell are one-body molded.
Beneficial effect: the utility model is by having increased heat-insulation layer outward at spiral ceramic skeleton skeleton, most heat can be flowed out with hot-air from outlet nozzle, not only improved service efficiency, the energy-conservation effect of playing, and use time safer, also greatly increased service life.
