Abstract
A chain saw air incoming device comprises an air filter cover and an air shielding plate. The air shielding plate can be mounted at two positions in the air filter cover according to high environment temperature and low environment temperature respectively. In spring, summer and autumn, the environment temperature is high, air incoming adopts the environment temperature, and an air inlet is positioned in the front; in winter, the environment temperature is low, air incoming direction is in the rear, and incoming air is air of a cooling air cylinder, so that incoming air temperature can be close to normal temperature. The chain saw air incoming device overcomes the defect of fluctuation of working performance due to environment temperature changes of existing chain saws.
Description
Technical field
The present invention relates to the chain saw air inlet system, particularly suction port device before and after the air filter cover.
Background technique
The suction port of existing miniature gasoline engine is all fixed in the market, and the temperature of air inlet is all ambient temperature.At low temperatures, cannot obtain relatively high intake temperature.Low temperature air inlet can cause engine performance to descend and the unsettled problem that turns round.
Summary of the invention
The invention provides a kind of chain saw air inlet system, can change according to complete machine Environmental Conditions temperature the device of suction port position, air filter cover front and back.
The technical solution used in the present invention is as follows:
A kind of chain saw air inlet system, comprise
The air filter cover, comprise cover body, the first bounding means and the second bounding means, the both sides inwall of cover body is fixed at the first bounding means two ends, which is provided with nose air intake, and the first locating slot arranged at the nose air intake periphery, the both sides inwall of cover body is fixed at the second bounding means two ends, which is provided with rear suction port, and the second locating slot arranged at this suction port periphery.
Barge board, be plugged in the first locating slot or the second locating slot.
Air filter cover inner face also is provided with diagram, identifies the different mounting point that used summer and used winter.
The beneficial effect that the present invention brings is:
Under normal temperature, use, barge board is arranged on the first bounding means, rear air inlet open, and air inlet is normal temperature air.In the low temperature using process, barge board is arranged on the second bounding means, from the cylinder air inlet.Inlet air has passed through the heating of cylinder, can obtain the air higher than ambient temperature.Thereby the intake temperature that has guaranteed motor is relatively stable.
The installation of barge board is without instrument, easy for installation.Be provided with the installation notch at the air filter cover, directly plug can be installed.After the air filter cover is installed, barge board and base withstand to deviate from, simple and reliable for structure.
Air filter cover inside buoy illustrates at the varying environment temperature, and the barge board mounting point identifies simple and clear.
The accompanying drawing explanation
Fig. 1 is chain saw air inlet system one embodiment's of the present invention structural representation;
Fig. 2 is another embodiment's of chain saw air inlet system of the present invention structural representation;
Fig. 3 is the panel schematic diagram of chain saw air inlet system of the present invention.
Embodiment
As depicted in figs. 1 and 2, the air filter cover comprises cover body 1, the first bounding means 2 and the second bounding means 3, the both sides inwall of cover body is fixed at the first bounding means two ends, which is provided with nose air intake 21, and the first locating slot 22 arranged at this suction port periphery, the both sides inwall of cover body is fixed at the second bounding means two ends, which is provided with rear suction port 31, and the second locating slot 32 arranged at this suction port periphery.Barge board 4 is plugged in the first locating slot or the second locating slot.
Described air inlet system is using method at normal temperatures: in ambient temperature during higher than 0 ℃, with rear suction port air inlet.Barge board is arranged on the first bounding means, stops the nose air intake air inlet.In ambient temperature during lower than 0 ℃, with front suction port air inlet.Barge board is arranged on the second bounding means, stops rear suction port air inlet.
Air filter cover inner face also is provided with diagram, identifies the different mounting point (see figure 3) that used summer and used winter.
