Description
Technical field
The utility model relates to a kind of heat gun, can open barbecue or other surfaces light rapidly charcoal bed or
Other solid fuels.
Background technique
United States Patent (USP) US7717104B2 discloses a kind of electric heating air pressure gun comprising a kind of heating unit of high-efficiency ceramic encapsulation
Part, the ceramic component separate out mouth no more than 8 millimeters, to generate high outlet temperature between 850-1100 ° of c, to work as the electricity
When the outlet of heat gun is placed in fuel surface, it is able to achieve rapid-ignition.Cold contact lid, handle and perforation outside heating element
Outer tube the safety that uses is provided.Heating element is entirely encapsulated in ceramics, in heating, durability and is all nothing in terms of the service life
With rival.Another feature of this electric heating air pressure gun is that it has a bracket, still warm heat gun can be hung, in this way
Bracket also combine with bottle opener.Existing deficiency is that the heating wire of heating element is helical duct of the solderless wrapped connection in skeleton
On, the gap that heater strip periphery is retained is less, and after being powered for a long time, heater strip fever excessively, still has the appearance of burning machine phenomenon.
Mouth is separated out no more than 8 millimeters secondly, heating element is placed on, although high outlet temperature can be generated, there is also hidden for safety
Suffer from.
Existing heat gun also has and heating wire is placed in ceramic through-hole, such as 201120162957.8 disclosure of Chinese patent
A kind of heat gun heating core ceramics bracket, radially have through-hole in ceramics bracket, there is partition, through-hole edge between through-hole
The number of plies of ceramics bracket radial direction arrangement is two layers or two layers or more, and heating wire is interspersed in these through-holes.This structure
Although heat generating component at work to air heat it is very abundant, each through-hole be it is independent, between through-hole and through-hole mutually
It is not connected to, generates heat during heating uneven, after long period use, be easy to produce high temperature, keep the heating wire of heat generating core easy
In blowing, heat gun is damaged, generates contingency.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provide a kind of improved heat gun, knot
Structure is simple, divulges information, and is not likely to produce high temperature, does not burn machine, and the service life is longer, uses safer.Main improve is improvement
The heat generating core ceramic stand structure of heat gun, there is good ventilation when heating wire being made to work, even if heating time is too long, also will not
Burning machine phenomenon is overheated in that can generate.
The technical solution of the utility model is: a kind of improved heat gun, including heat generating core, air-supply assembly, power supply
Component, the heat generating core are encapsulated in mica inner tube, are cased with metal tube outside mica inner tube, metal tube is externally provided with the metal of perforation
Protection pipe, it is characterised in that heat generating core is made of ceramics bracket and heating wire, and the center in columned ceramics bracket is opened
There is a central through hole, the central through hole periphery is uniformly distributed a circle and the homoaxial multiple through-holes of central through hole, described
Each through-hole one is connected to by seam between central through hole, heating wire is interspersed in part or all of through-hole.
Further, above-described central through hole and the through-hole for being distributed in its outer ring, are round hole, are evenly distributed on
The number of openings of central through hole outer ring is 4-10, most preferably 6-7.Ceramics bracket is an important composition portion of heat generating core
Point, heating wire can be theoretically placed in part or all of through-hole, heating wire can also be placed in central through hole, to guarantee fever effect
Fruit is most preferably that heating wire is equipped in whole through-holes, and central through hole also places heating wire when necessary.The close fever for being coiled into spring like
Silk passes through a through-hole in ceramics bracket, then turns back and pierce into adjacent through-hole, and so on operates, until each through-hole or portion
Divide in through-hole until putting on heating wire.Further, the outer end of at least one seam is equipped with heating wire mistake in ceramics bracket
Bridge needs when interspersed through-hole is non-conterminous when needing to place heating wire in central through hole or before and after heating wire by gap bridge
It is crossed over as support, keeps heating wire relatively fixed difficult to slide.Since the through-hole of outer ring is all interconnected with central through hole, lead to
Wind effect is good, it is not easy to generate excessively high temperature and fever uniformly, guarantee that heat gun is not easy to burn machine, securely and reliably.
The width of seam between each through-hole and central through hole is less than the diameter of the spring section of heating wire, to prevent heating wire sliding
Seam out.
Ceramics bracket to make heating wire not generate disorderly sliding phenomenon when entering another through-hole from a through-hole, between adjacent through-holes
Outer end partition wall be equipped with lower concave block, heating wire across the lower concave block on partition wall enter next through-hole.
Groove is in axial direction provided on columned ceramics bracket outer surface between adjacent through-holes.Groove plays cooling wind
Road effect can increase the space between ceramics bracket and mica inner tube, and the high temperature that heating wire generates is easy to distribute, and improve heat dissipation
Effect reduces the heat for being conducted to outer sleeve, thus does not allow easy burn-out air-heater, avoids generating contingency.
The groove being in axial direction provided on columned ceramics bracket outer surface between adjacent through-holes is arc groove, arc
Connected in star not only can guarantee maximum groove area, but also be able to maintain the intensity of ceramics bracket.On ceramics bracket outer surface outside through-hole
Axial direction is equipped with linear rib, and when ceramics bracket is placed into fever rifle mica inner tube, linear rib meets inner tube Shi Yuqi
Line contact is formed, is not easy to block, is easy installation.
Ceramics bracket head at heat gun outlet end is equipped with a ceramic seal heads, the ceramic seal heads be equipped with
The through-hole of ceramics bracket central through hole and outer ring is corresponding and the centre bore and cycle hole that are connected, have between centre bore and cycle hole every
Wall is not connected to mutually, and ceramic seal heads one end is equipped with multiple raised lines, and raised line number is less than or equal to the groove number of ceramics bracket outer surface
Amount, raised line are inserted into a groove.This mutually matched kiss binding structure makes end socket and ceramics bracket form bonding relation, ceramics
The presence of end socket exports heat generating core with heat gun and maintains a certain distance, and is not connected to mutually between each hole of ceramic seal heads, increases
Bonding strength, it is safer while guaranteeing to export acquisition high temperature.
Further, the diameter of ceramic seal heads is equal or slightly larger than ceramics bracket diameter, is most preferably that ceramic seal heads diameter is big
In ceramics bracket diameter 20-30.This design makes ceramic seal heads and mica inner tube is closer is affixed, and related heat generating core is stablized
It is encapsulated in mica inner tube.
The thickness of the ceramic seal heads is greater than 8mm, most preferably 8.5-15mm, this distance can guarantee that outlet is high well
Temperature, but also with good safety.
Handle is housed on the outermost protection metal pipe of heat gun, for hanging over other devices such as barbecue rack, side
Just it takes.
The utility model has the advantages that this heat gun of the utility model, structure is simple, and heat generating core ventilation effect is good, is not easy to form height
Temperature, along with fever core head is equipped with ceramic seal heads, bonding strength is big, and use is safer.
