Model utility content
The utility model provides a kind of external assembly of secondary air filter that can carry out prefiltration to the air entering air filter of internal combustion engine, the external assembly of this secondary air filter can discharge the water droplet being attached to its inwall simultaneously, prevent the water vapour of water drops vaporize from entering the cylinder of internal-combustion engine, affect the normal operation of cylinder.
The utility model scheme is as follows: the external assembly of secondary air filter, comprise housing and be arranged on the filter core in housing, housing is provided with air inlet and air outlet channel, air inlet is positioned at the sidewall of housing, air outlet channel is positioned at the end of housing, the outer surface of filter core is relative with air inlet, the first air flue is formed between filter core outer wall and inner walls, filter core inside has cavity and forms the second air flue, filter core is connected with air outlet channel the second air flue is communicated with air outlet channel, the one end being positioned at air outlet channel is on the housing provided with drain opening along the radial direction of air outlet channel, drain opening communicates with the first air flue, drain opening and air inlet homonymy.
This programme working principle is as follows: during use, the external assembly of the utility model secondary air filter is arranged on the front of original air filter of internal combustion engine, both are linked together by hollow tube, first such air enters into the first air flue by the air inlet of the external assembly of this secondary air filter, air is through the prefiltration of filter core, filter out the fine particle of air hole, air enters into the second air flue, enter air outlet channel by the second air flue, send into original air filter of internal combustion engine via hollow tube from air outlet channel.
The beneficial effects of the utility model: 1. can carry out prefiltration to the air entering into original air filter of internal combustion engine, the fine particle in filtering air, the air through prefiltration is more clean, avoids the wearing and tearing of cylinder of internal-combustion engine, piston, bent axle; 2. the setting of drain opening, can discharge the little water droplet be attached on air filter inwall timely, avoid the accumulation of water droplet, and after avoiding temperature to raise, water drops vaporize becomes water vapour to enter cylinder with air, affects the normal operation of cylinder.
To sum up, the working life by using the external assembly of the utility model secondary air filter can improve internal-combustion engine.
Further, housing comprises air filter main body and end cap, and air filter main body and end cap removably connect, and air outlet channel and drain opening are all arranged on end cap.Housing is arranged to split-type structural, is easy to remove and repair.
Further, air inlet is the long strip entrance axially arranged along housing, and the width direction along air inlet is evenly equipped with multiple dividing plate.This kind of design, can guarantee that air filter has rational air inflow.
Further, the joint by hollow between filter core with air outlet channel is connected, and joint one end extend in the second air flue, and the other end is connected with the outer wall thread of air outlet channel.The two ends of filter core are respectively equipped with cartridge support frame, and wherein the cartridge support frame of one end and joint clamping, be provided with stage clip between the cartridge support frame of the other end and the inwall of air filter main body.Filter core supports more stable by two cartridge support framves; Simultaneously, because joint is connected with the outer wall thread of air outlet channel, the cartridge support frame clamping of joint and wherein one end, and the cartridge support frame of the other end is supported by stage clip, therefore, make joint relative to the outer wall precession of air outlet channel or back-out by swivel joint, the axial position of adjustable filter core, thus regulate the overlapping area between filter core outer surface and air inlet, thus change the filter efficiency of filter core local.
Further, conveniently dismantle, air filter main body is threaded with end cap.
Further, the cylindrical of air filter main body is respectively equipped with the first baffle plate and the second baffle of ring-type, the draw-in groove of ring-type is formed between first baffle plate and second baffle, the cylindrical of second baffle has two grooves inserted for end cap, the inner circumference of end cap is provided with two projections for end cap clamping, one of them projection and drain opening are positioned at same radial position, and another projection is along the diametrically setting of end cap.The side direction being positioned at groove in described draw-in groove is provided with limiting stopper.
Design based on said structure, the installation method of air filter main body and end cap is: first two of end cap projections are aimed at two grooves that second baffle is offered, then the axis along air filter main body inserts end cap, last rotating end cap, projection is connected in the draw-in groove of ring-type, thus connects air filter main body and end cap.
In said structure, because two grooves are symmetricly set on the both sides of drain opening, two projections are symmetricly set on the both sides of drain opening, and position corresponding with drain opening in draw-in groove is provided with limiting stopper, therefore, when projection docks with groove, first make drain opening upward, after end cap inserts, end cap is clockwise or be rotated counterclockwise 180
oafter, because limiting stopper is to the barrier effect of projection, end cap cannot rotate again, and now the projection of end cap is connected in the draw-in groove of air filter main body completely, realize end cap and be connected with the quick of air filter main body, and simultaneously, drain opening rotates 180
oafter just in time down, be positioned at best position.Said structure, effectively can prevent the uncertainty that drain opening position is installed.
Further, the inner circle of end cap has first ladder in large footpath and the second ladder of path, and projection is positioned on the first ladder, the table top between the first ladder and the second ladder when projection is connected in draw-in groove and the end face of housing offset.Due to the table top between the first ladder and the second ladder when projection is connected in draw-in groove and the end face of housing offset, therefore, when housing and end cap clamping, the stability of housing and end cap clamping can be increased.
Further, surrounding housing being positioned at air inlet is evenly equipped with leg, and leg inside is axially arranged with internal thread along it, is provided with stiffening rib between two legs on air inlet width direction.Owing to being provided with internal thread in leg, when therefore installing, make the external assembly of this secondary air filter and other anatomical connectivity by T-shaped bolt, stiffening rib can strengthen the intensity between two legs.
