Abstract
The utility model relates to an improved structure of a hot melt glue gun, which is provided with a gun shell. The utility model is characterized in that a heat generating shell body is arranged in the gun shell; one end of the heat generating shell body is sheathed with a glue sleeve for bearing a glue bar, and the opposite other end is connected with a gun nozzle; the heat generating shell body is also provided with a heat generating chamber; a heat generating element is inserted in the heat generating chamber; the heat generating element is particularly and mainly composed of a bar body and a metal thick-film electronic slurry layer coated on the bar body; the metal thick-film electronic slurry layer forms an electric connection with conducting wires of a power supply. Therefore, the heat generating element of the hot melt glue gun with the structure is difficult to break down. The power density reaches 30 w to 60 w/ cm 2. The utility model has the advantages of shock resistance and impact resistance. The material of the utility model has the function of environmental protection and has no toxicity. The force of the electric heating rate is further enhanced. Consequently, the glue melting efficacy of the electric melt glue gun can be improved.
Description
Technical field
The utility model is the structure-improved about a kind of thermosol gelgun, particularly a kind of insulating properties height, and the antivibration shock resistance, the material environment friendly avirulence can further improve the structure-improved of the thermosol gelgun of electric heating rate power.
Background technology
Thermosol gelgun mainly be widely used between the object in fields such as building, fitting-out work, electronic apparatus, toy, furniture manufacturing bonding.But, existing on the market hot glue rifle heating structure is to clip the P.T.C ceramic heating element by two sheet metals, they are wrapped as insulating materials with polyimide film again, separate contacting of heater element and metal melten gel shell, yet this P.T.C ceramic heating element material has certain moisture absorption, in wet weather, make moist easily and electrical breakdown takes place, be short-circuited, influence work, and P.T.C ceramic heating element material can not be operated in higher warm area, operating power is subjected to the influence of its intrinsic characteristic, can not do too much.In addition, the P.T.C ceramic heating element contains lead, to very not environmental protection of environment.Certainly, industry also has the mode that heating wire is twined in employing to make heater element, and as Chinese patent 01235632.8, but this kind mode drawback is that heating wire easily volatilizees because of high temperature when under the condition of large power long time service, even fusing.
Summary of the invention
For overcoming above-mentioned defective, the purpose of this utility model promptly is to provide a kind of insulating properties height, the antivibration shock resistance, and the material environment friendly avirulence can further improve the structure-improved of the thermosol gelgun of electric heating rate power.
The purpose of this utility model is achieved through the following technical solutions:
The structure-improved of a kind of thermosol gelgun of the utility model, be provided with the rifle shell, in this rifle shell, be provided with the heating housing, this heating housing one end is arranged with the gum cover of accepting the glue rod, the relative other end is connected with the rifle mouth, also is provided with the heating chamber on this heating housing, is inserted with heater element in this heating chamber, especially this heater element mainly is made up of barred body and the metal thick-film electronic slurry layer that is coated on this barred body, and this metal thick-film electronic slurry layer is electrically connected with power lead and forms the loop.
In the structure-improved of above-mentioned thermosol gelgun:
Wherein this heating accent place also is provided with the silicon rubber that is used for sealing this heater element.
Be provided with collet between this heating housing and the gum cover.
This rifle shell offers louvre at the housing place of this heating housing of parcel.
On above-mentioned basis, the barred body of this heater element is stainless steel solid barred body, ceramic solid barred body, the hollow barred body of stainless steel or ceramic hollow barred body.In addition, on this basis, also be provided with insulating barrier on this heater element, this insulating barrier is meant dielectric paste layer or mica splittings.
Because the structure-improved of the utility model thermosol gelgun has adopted above-mentioned ameliorative measure, so heater element solved the problem of electric cocainine volatilization in the prior art or fusing, and based insulation intensity is difficult for puncturing greater than 1250VALmin, and power density reaches 30-60W/CM
2, the antivibration shock resistance, the material environment friendly avirulence has further improved electric heating rate power, thus the melten gel that improves electric melting glue gun is renderd a service.In addition,, on the rifle shell, offer louvre, can also prevent that therefore hot melt colloidal sol from flowing backwards, make gum cover anti-aging, and then prolong the service life of thermosol rifle owing to adopted collet.
Description of drawings
In order to be easy to explanation, the utility model is done to describe in detail by following preferred embodiment and accompanying drawing.
Fig. 1 is the structure improved schematic perspective view of the utility model thermosol gelgun.
Fig. 2 is the schematic diagram of the structure improved heater element of the utility model thermosol gelgun.
Fig. 3 is the decomposing schematic representation of interior each parts (wherein the part parts are by section) of the structure improved rifle shell of the utility model thermosol gelgun.
The specific embodiment
Please together referring to figs. 1 to Fig. 3, the structure-improved of the utility model thermosol gelgun is provided with rifle shell 1, is provided with heating housing 2 in this rifle shell 1, and these heating housing 2 one ends are arranged with the gum cover 4 of accepting glue rod 3, and the relative other end is connected with rifle mouth 5.
This rifle shell 1 offers louvre 12 at the housing place of this heating housing 2 of parcel.Between this heating housing 2 and gum cover 4, also be provided with collet 6, this collet 6 is to be made by a kind of exotic material, also be provided with heating chamber 21 on this heating housing 2, be inserted with heater element 23 in this heating chamber 21,21 mouthfuls of places also are provided with silicon rubber 25 in this heating chamber, are used for sealing this heater element 23.Wherein this heater element 23 mainly by barred body 231 and sintering the metal thick-film electronic slurry layer 233 on this barred body 231 (this metal thick-film electronic slurry layer 233 is that conductor paste layer and resistance slurry layer are formed, its production technology and operation principle are prior art, this does not do detailed description the place) form, this metal thick-film electronic slurry layer 233 is connected and forms the loop with power lead 235, when electric current passes through this metal thick-film electronic slurry layer 233, this metal thick-film electronic slurry layer 233 promptly can generate heat, and the heat that is produced promptly can conduct heat by the housing in heating chamber 21 and heat to heating housing 2 and then to glue rod 3.The barred body 231 of this heater element 23 can be any resistant to elevated temperatures barred bodies such as stainless steel solid barred body, ceramic solid barred body, the hollow barred body of stainless steel or ceramic hollow barred body.
In addition, the surface of this heater element 23 also is provided with insulating barrier 237, and this insulating barrier 237 is meant the dielectric paste layer (this its production technology of dielectric paste layer and operation principle are prior aries, so do not do detailed description at this) that sinters formation into, this dielectric paste layer dielectric strength height is difficult for puncturing.This insulating barrier 237 or be meant the mica splittings that wraps.
