Abstract
The invention relates to the technical field of air filters of small gasoline engines, in particular to a reverse jetting preventing air filter. The air filter comprises an air filter fixing plate, filtering cotton, a knob and an air filter cover, wherein a round hole is formed in the air filter fixing plate; and the knob is fixed through the round hole by using a tapping screw and a flat gasket. The air filter can be converted in two states (such as an idling state and a high-speed state) by rotating the top of the knob at a certain angle, so that the working requirement is met, namely an air door is closed in the idling state, and air is fed and reverse jetting is prevented in the high-speed state. The reverse jetting preventing air filter is simple in structure and reasonable in design.
Description
Technical field
The present invention relates to air filter technical field, particularly a kind of miniature gasoline engine, Novel air filter with counter-jetting resistance structure.
Background technique
Existing miniature gasoline engine there will be engine cylinder air-breathing too fast and air inlet that cause is not smooth when engine speed is higher in the market, thus the phenomenon that causes a kind of inflammable gas to regurgitate along air filter intake duct direction.But the less employing counter-jetting resistance of current existing air filter structure, or the counter-jetting resistance complicated structure of design, part is more, is not easy to mounting or dismounting, has increased cost of production, and then has affected working efficiency, and economic benefit can not get improving.If this phenomenon of regurgitating of machine long-term existence, will cause air filter to be wet by oil immersion, even oil dripping.Thereby cause the engine charge resistance to increase, the waste fuel oil, reduce engine power, causes user's economic loss.
Summary of the invention
The invention provides a kind of miniature gasoline engine counter-jetting resistance air filter, is a kind of counter-jetting resistance air filter simple in structure, reasonable in design.
The technical solution used in the present invention is as follows:
A kind of miniature gasoline engine counter-jetting resistance air filter, comprise
The air filter fixed plate, which is provided with air hole;
Filter pulp, which is provided with accommodating through hole;
Knob, comprise that rotary knob rod, first rotates plectane and second and rotates plectane, and axial along rotary knob rod, the first slewing circle plate hight arranges in the second rotation plectane;
The air filter cover, cover in outside the air filter fixed plate.
After rotary knob rod one end wears accommodating through hole, be fixed in the air filter fixed plate.Fixing employing tapping screw, and there have plain cushion to be matched with to be described, described air filter fixed plate is provided with circular hole, and knob is used by circular hole and is fixing.The outside is filter pulp and air filter cover.Described, described air filter knob rotates certain angle by tip position, thereby carries out the conversion (idling mode and fast state) of two states, to reach work requirements---close air door during idling, air inlet prevent from regurgitating during high speed.
The beneficial effect that the present invention brings is:
In the present invention, when engine idle is worked, knob is closed condition, to stop entering in a large number of air, in order to well machine is carried out to cold start-up.After machine starts, air enters in a large number.Motor enters the angle that fast state need to be certain by knob becomes open mode, thus air inlet effectively stop engines combustible gas to be regurgitated in air filter filter pulp during high speed.
The accompanying drawing explanation
The STRUCTURE DECOMPOSITION schematic diagram that Fig. 1 is air filter of the present invention;
Fig. 2 is air filter work one view of the present invention;
Fig. 3 is another view of air filter work of the present invention.
The label that in figure, component names is corresponding is as follows:
1, tapping screw; 2, plain cushion; 3, air filter fixed plate; 4, filter pulp; 5, knob; 6, air filter cover.
Embodiment
As shown in Figure 1, chain saw air inlet system of the present invention, comprise
As the embodiment of counter-jetting resistance air filter of the present invention, as shown in Figure 1, knob 5 is fixed on air filter fixed plate 3 by plain cushion 2 use self tapping screws 1 through after filter pulp 4, finally loads onto air filter cover 6.
The air filter fixed plate is provided with air hole 31.Knob 5 comprises that rotary knob rod 51, first rotates plectane 52 and second and rotates plectane 53, and axial along rotary knob rod, the first slewing circle plate hight arranges in the second rotation plectane.Rotary knob rod one end is fixed in the air filter fixed plate after wearing the accommodating through hole 41 that filter pulp is provided with.
As shown in Figures 2 and 3, during work, only need the top of turn knob to turn over an angle, the conversion in the time of can completing two states.During idling, second rotates plectane closes air hole 31, and to stop entering in a large number of air, the needs of the choke reached, in order to well carry out cold start-up to machine.During high speed, first rotates plectane opens air hole 31, reaches a kind of obstruction that inflammable gas is regurgitated, thereby produce, puts back the spray effect.
In the present embodiment, described top knob portion has several pits in order to location, and boss increasing friction force when rotating is arranged.
Claims (2)
1. a miniature gasoline engine counter-jetting resistance air filter, comprise
The air filter fixed plate, which is provided with air hole;
