Description
Technical field
The utility model relates to power engine technical field, especially relates to a kind of radiating structure of handheld power machine muffler.
Background technique
Power is large, volume is little owing to having for handheld power machine, lightweight, shake the features such as little, structure is simple, easy to maintenance, cost is low, become the key machine in China's garden instrument.Handheld power machine generally provides power by single cylinder internal combustion engine, and baffler is arranged on the exhaust port place of motor for collecting waste gas and the discharge of cylinder body generation, discharges the heat of cylinder body while exhaust.Due to the constraint of size and weight, baffler can not do very large.Along with the raising that people require environmental protection aspect, most of machinery adds catalyst in silencing apparatus, does harmless process, to reach the requirement of exhaust emissions to the waste gas of discharging.This makes baffler volume become less.In addition, in order to user's safety protection, NBS has the aperture of regulation baffler radiation hole not insert finger.These restrictions make the radiating effect of baffler poorer.If the heat of silencing apparatus can not be discharged in time, can cause handheld power machine can not long-time stable work.Also internal component damage can be caused if service time is long.Chinese patent Authorization Notice No. CN100529343C, authorized announcement date on August 19th, 2009, the patent of invention open file that name is called " muffler ", provides a kind of muffler structure for internal-combustion engine.This structure has a housing, and this housing has the suction port of waste gas and leaves the relief opening of housing, and wherein waste gas flows through a reaction zone in housing, and waste gas circulates at least partly in this reaction zone, and waste gas forms annularly flow in this reaction zone.This structure for handheld power machine use structure too complexity add manufacture cost.
Summary of the invention
In order to solve the bad technical problem affecting equipment use of baffler radiating effect that prior art handheld power machine exists, the utility model provides the baffler of the handheld power machine of the simple good heat dissipation effect of a kind of structure.
The technical solution of the utility model is: a kind of heat radiation baffler of handheld power machine, it comprises frame, the cylinder fixing with frame and baffler, baffler is tightly connected by baffler body and baffler lid and forms cavity body structure, baffler body is provided with the inlet hole be communicated with cylinder, baffler is covered with the exhaust port be communicated with air, and inlet hole is connected with honeycomb duct, is provided with axial-flow blower between baffler inner chamber honeycomb duct and exhaust port.Baffler rapid heat dissipation, guarantees the work of handheld power machine energy long-time stable.Do not change baffler volume profiles, applied widely.
As preferably, inlet hole is positioned at baffler body bottom portion, and exhaust port is located at baffler and covers portion, and the import of honeycomb duct is communicated with inlet hole, and the outlet of honeycomb duct is corresponding with exhaust port position.
As preferably, the blade of blower fan is aimed in the outlet of honeycomb duct; Ventilation effect is good, is conducive to heat to be discharged from exhaust port.
As preferably, exhaust port is provided with grid; Prevent finger from inserting injured, guarantee user's safety.
Compared with prior art, the beneficial effects of the utility model are: baffler rapid heat dissipation, guarantee the work of handheld power machine energy long-time stable.Simple and reasonable, convenient for installation and maintenance, manufacture user cost low.
