Abstract
This utility model patent discloses the deafener wind-lead-cover structure of a kind of two-stroke gasoline engine, and this deafener wind scooper is in about 900Bending and be arranged on the outside of deafener, bootable cooling wind, to deafener air vent, the temperature that this kind of deafener wind scooper coordinates cooling wind to greatly reduce engine exhaust port, has met emission request.
Description
Technical field
This utility model patent relates to a kind of two-stroke gasoline engine technical field, particularly to a kind of deafener wind scooper.
Background technology
Requirement and cry to environmental protection are more and more higher the most in the world, and mostly pass through in the deafener of low emission level engine
Catalyst reduces discharge, but can produce amount of heat when catalyst runs into waste gas cracking and cause the air vent temperature of electromotor
Spend the highest, if the air vent of electromotor is easy to cause fire near dry, inflammable object when using machine.The most beautiful
In state's USDA regulation, the temperature for engine exhaust port there has also been particularly severe requirement, and the deafener of current band catalyst is several
The requirement of USDA can not be reached.Although the first half when low emission level engine supporting wind-driven cleaning machine or sprayer-duster use
Spiral case has proprietary cooling air channel cooling deafener, but the most obvious to deafener air vent cooling effect.This
The invention of the deafener wind scooper of money two-stroke gasoline engine coordinates cooling wind action to be fully able to make the temperature of air vent to reach
Laws and regulations requirement.
Summary of the invention
The purpose of this utility model is to provide the deafener wind scooper of a kind of two-stroke gasoline engine, this deafener wind scooper in
About 900Bending and be arranged on the outside of deafener, bootable cooling wind is joined to deafener air vent, this kind of deafener wind scooper
Close cooling wind and greatly reduce the temperature of engine exhaust port, meet emission request.
The technical scheme of this utility model patent is: the deafener wind scooper of a kind of two-stroke gasoline engine is in about 900Bending,
Described deafener wind scooper and deafener air vent corresponding position are provided with multiple steam vent, and one end of described steam vent is additionally provided with installation
Hole, the plane of described steam vent and the plane of installing hole are provided with spacing, when described deafener wind scooper is arranged on outside deafener
During side, forming spacing passage between described deafener wind scooper and deafener, deafener cooling wind enters noise reduction through spacing passage
Discharge from steam vent after device air vent.
Provide the benefit that: in about 900The deafener wind scooper of bending is arranged on the outside of deafener, by between the two
Gap guides cooling wind to deafener air vent, the temperature at chill vent, meets developed country to deafener aerofluxus
The safety requirements of mouth temperature.
Accompanying drawing explanation
Accompanying drawing described herein is used for providing being further appreciated by of the present utility model, constitutes one of the present utility model
Point, this schematic description and description is used for explaining this utility model, is not intended that improper restriction of the present utility model.

Sequence number explanation in accompanying drawing: 1, silencer body；2, screw；3, steam vent；4, deafener wind scooper；5, air vent；6、
Installing hole；7, spacing passage.
Detailed description of the invention
As shown in Figure 1, Figure 2, Figure 3, Figure 4, the deafener wind scooper 4 of two-stroke gasoline engine is fixed on by installing hole 6 and disappears
On sound body 1, steam vent 3 is corresponding with air vent 5, forms spacing passage 7 between deafener wind scooper 4 and silencer body 1.
Detailed description of the invention: during gasoline engine work, the high-temp waste gas of generation is discharged from the air vent of deafener, then through noise reduction
The steam vent of device wind scooper is discharged, and meanwhile, the cooling wind of cooling deafener is guided by the deafener wind scooper of about 90 ° of bendings
Enter spacing passage, enter deafener exhaust ports along spacing passage, discharge through steam vent.
The beneficial effects of the utility model are: utilize deafener wind scooper to make the high-temp waste gas that cooling wind is discharged with electromotor
Mix, thus greatly reduce the temperature of engine exhaust port, improve machine safety in utilization.
