General small-size gasoline engine, because of its simple in construction, compact volume and convenience, is largely used in hand-held machine instrument, market
Demand is big.Two-stroke gasoline engine is due to its operation principle at present, and its raw emissions is difficult to reach relevant laws and regulations mark
Alignment request, it is necessary to carry out external purification, the major way of current external purification is increase catalyst in deafener, makes waste gas exist
Carrying out second-time burning in deafener, the waste gas after second-time burning is directly discharged by exhaustor, and this results in machine running process
In there will be flame phenomenon at deafener air vent, reliability and safety can be poor, or is arranged by brief emission path
Go out outside deafener, although, also there is the phenomenon that certain flame is eliminated, but can not the most reliably meet requirement.Such as Patent No.
ZL201420160670.5, a kind of two-stroke gasoline engine silencer body, upper shell combination is provided with air vent, inside exhaust pipe and outer row
Trachea, inside exhaust pipe and outer exhaustor are positioned at the both sides of air vent, form exhaust passage, although add exhaust passage away from
From, but some fire combustion can't be extinguished completely, does not meets the strict demand of external flame safety, therefore, is badly in need of a kind of structure letter
Single, exhaust pathway is longer, meets the safety requirements that deafener extinguishes completely.
Summary of the invention
The purpose of this utility model is a kind of deafener Anti-flame structure of design, is changed into by two cavity configurations of conventional deafener
Three-cavity structure, is i.e. divided into a chamber two chambeies with dividing plate, and extends aerofluxus distance by increasing spoiler, and air vent increases anti-
The network of fire, hood, hood, with the air vent being evenly distributed, makes tail gas uniformly to spread.
This utility model adopts the technical scheme that: a kind of deafener Anti-flame structure, has one and is separated into by dividing plate
First chamber and the housing in the second chamber, described first intracavity, housing wall is provided with the fluid dividing cover engaged with gasoline engine air vent, and
Being arranged on dividing plate the catalyst making gas carry out second-time burning, described second chamber exhaust ports is provided with the waste gas after discharging burning
Flame screen, it is characterised in that: described second chamber also includes point cavity plate that cavity is divided into epicoele and cavity of resorption, in described point of cavity plate
It is fixedly mounted with connection epicoele and the exhaustor of cavity of resorption.
Preferably, described cavity of resorption is placed in parallel n spoiler.
Further, one end of described spoiler shell wall with point cavity plate or cavity of resorption respectively connects firmly, and connects firmly with point cavity plate
Spoiler and and the spoiler interval that connects firmly of the shell wall of cavity of resorption and staggered relatively.
Preferably, described dividing plate is installed and is provided with through hole at catalyst, and described through hole is positioned at intracavity.
Further, described fluid dividing cover is provided with tap hole.
Preferably, described flame screen is externally provided with hood.
Further, described hood is provided with multiple steam vent.
Provide the benefit that: the deafener Anti-flame structure of new improvement and the muffler structure phase of traditional normal tape catalyst
Ratio, new structure can effectively reduce exhaust ports temperature in machine running process, thoroughly solves flame phenomenon, and this just makes product
Safety and the reliability of product are all greatly improved, and meet the safety requirements that deafener is stopped working by developed country.

Detailed description of the invention
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of deafener Anti-flame structure, include epicoele including first chamber the 11, second chamber 1(
20, cavity of resorption 21, air vent 14, point cavity plate 9), fluid dividing cover 4(include tap hole 19), exhaustor 8, spoiler (include spoiler one
16, spoiler 2 10, spoiler 3 15), dividing plate 2(include through hole 23), catalyst member (include air inlet 22, catalyst cover
6, mesh catalyst 7), exhaust component (including hood 12, flame screen 13, steam vent 17) composition.
Deafener is divided into the 11, second chamber 1, the first chamber by dividing plate 2, and the second chamber 1 is divided into epicoele 20, cavity of resorption by point cavity plate 9
21；Interior siphunculus 5 runs through in the first chamber 11 and the second chamber 1, connects firmly on muffler shell.
Fluid dividing cover 4 is packed on ring flange 3, and ring flange 3 is arranged on the cylinder exhaust on the first chamber 11 wall with gasoline engine 18
Mouth junction.
Dividing plate 2 is provided with multiple through hole 23, and through hole 23 is the first chamber 11 and unique passage in the second chamber 1, is placed in the first chamber
11 mesh catalyst 7 that are interior and that be packed on dividing plate 2 are corresponding with through hole 23, and the catalyst cover 6 being provided with multiple air inlet 22 is pacified
