Abstract
The present invention provides the deafener radiator structure of a kind of handheld power machine, relates to engine technical field.It includes frame, the cylinder being located in frame and the deafener being connected with cylinder, deafener is for sealing cavity body structure, and deafener is provided with the air inlet connected with cylinder and the steam vent with atmosphere, air inlet connects mozzle, is provided with blower fan between suppressor lumen mozzle and steam vent.The present invention solves the bad technical problem affecting equipment use of deafener radiating effect that in prior art, handheld power machine exists.The invention have the benefit that deafener rapid heat dissipation, it is ensured that handheld power machine energy long-time stable works.Simple and reasonable, convenient for installation and maintenance, manufacture use cost low.Decrease use cost.
Description
Technical field
The present invention relates to engine technical field, especially relate to the radiator structure of a kind of handheld power machine muffler.
Background technology
Handheld power machine owing to having that power is big, volume is little, lightweight, shake the features such as little, simple in construction, easy to maintenance, low cost, it has also become the key machine in China's garden instrument.Handheld power machine is typically provided power, deafener to be arranged at the exhaust port of electromotor for collecting waste gas and the discharge that cylinder body produces by single cylinder internal combustion engine, discharges the heat of cylinder body while aerofluxus.Due to size and the constraint of weight, deafener will not be made the biggest.The raising required environmental conservation aspect along with people, most of machineries add catalyst in acoustic filter, and the waste gas discharged is done harmless process, to reach the requirement of exhaust emissions.This makes deafener volume become less.It addition, in order to user safeguard protection, national standard has the aperture of regulation deafener louvre can not insert finger.The radiating effect that these restrictions make deafener is worse.If the heat of acoustic filter can not be discharged in time, handheld power machine can be caused long-time stable not work.If using overlong time to also result in internal component damage.Chinese patent Authorization Notice No. CN100529343C, authorized announcement date on August 19th, 2009, the patent of invention open file of entitled " muffler ", it is provided that a kind of muffler structure for internal combustion engine.This structure has a housing, and this housing has the air inlet of waste gas and leaves the air vent of housing, and wherein waste gas flows through a reaction zone in housing, and waste gas at least partly circulates in this reaction zone, and waste gas forms annularly flow in this reaction zone.This structure uses for handheld power machine that structure is the most complicated adds manufacturing cost.
Summary of the invention
In order to solve the bad technical problem affecting equipment use of deafener radiating effect that prior art handheld power machine exists, the present invention provides the deafener of the handheld power machine of a kind of simple in construction good heat dissipation effect.
The technical scheme is that the deafener radiator structure of a kind of handheld power machine, it includes frame, the cylinder being located in frame and the deafener being connected with cylinder, deafener is for sealing cavity body structure, deafener is provided with the air inlet connected with cylinder and the steam vent with atmosphere, air inlet connects mozzle, is provided with blower fan between suppressor lumen mozzle and steam vent.Deafener rapid heat dissipation, it is ensured that handheld power machine energy long-time stable works.Do not change deafener volume profiles, applied widely.
As preferably, deafener includes deafener body and deafener lid, and air inlet is positioned at deafener body bottom portion, and steam vent is located at deafener and covers portion, and the import of mozzle connects with air inlet, and the outlet of mozzle is corresponding with steam vent position.Assembling is facilitated to safeguard.
As preferably, blower fan is axial fan, the blade of the outlet alignment blower fan of mozzle；Ventilation effect is good, is conducive to discharging heat from steam vent.
As preferably, steam vent is provided with grid；Prevent finger from inserting injured, it is ensured that user safety.
Compared with prior art, the invention has the beneficial effects as follows: deafener rapid heat dissipation, it is ensured that handheld power machine energy long-time stable works.Simple and reasonable, convenient for installation and maintenance, manufacture use cost low.Decrease use cost.

Detailed description of the invention
Below by embodiment, and combine accompanying drawing, technical scheme is described in further detail.
Embodiment 1:
As shown in Figure 1,2 and 3, the deafener radiator structure of a kind of handheld power machine, it includes frame 1, the cylinder 3 being located in frame 1 and the deafener 2 being connected with cylinder 3.Deafener 2 is located at cylinder 3 exhaustor side.Deafener 2 is for sealing cavity body structure, and deafener 2 is shaped like in cuboid.Deafener 2 includes deafener body 24 and deafener lid 21.Deafener 2 is provided with the air inlet 241 connected with cylinder 3 and the steam vent 211 with atmosphere.Deafener body 24 left end closes right-end openings, and blind end is bottom deafener body 24.Deafener body 24 opening is provided with flanging and forms flanging groove, and deafener lid 21 surrounding embeds flanging groove formation deafener body 24 and seals with deafener lid 21.Air inlet 241 is positioned at centre position bottom deafener body 24.Air inlet 241 connects mozzle 23.Mozzle 23 is straight tube.The import of mozzle 23 connects with air inlet 241, the outlet of mozzle 23 and deafener body 24 inner space.Steam vent 211 is located at deafener lid 21 top.It is provided with blower fan 22 between deafener 2 inner chamber mozzle 23 and steam vent 211.Blower fan 22 is axial fan.Deafener body 24 inner chamber is provided with support, and support surrounding is fixed with deafener body 24 inwall, is connected with rotating shaft one end of blower fan 22 by bearing in the middle of support.The other end of blower fan 22 rotating shaft is connected with deafener lid 21 by bearing.The blade of the outlet alignment blower fan 22 of mozzle 23.The outlet of mozzle 23 is positioned at the left side of blower fan 22 blade, and steam vent 211 is positioned at the right side of blower fan 22 blade.In order to aerofluxus is fast, the present embodiment is provided with two steam vent 211 horizontal arrangement, high as the outlet with mozzle 23.Steam vent 211 is oval, and two steam vents 211 occupy deafener lid 1/21st 4 area.In order to prevent steam vent 211 via area excessive, cause user finger to insert injured, in the middle of steam vent 211, be provided with grid 212.
