The drain valve of the air filter comprises a drain pipe and a sealing washer, wherein the drain pipe is fixedly arranged on a shell of the air filter in a penetrating manner; the drain pipe comprises a water inlet segment and a water outlet segment; the water inlet segment is provided with a water inlet, and a clearance is reserved between the water inlet and the shell; the water outlet segment is provided with a water outlet, and the water outlet is provided with a diagonal plane which faces upward; the sealing washer is rotatably connected with the water outlet. According to the drain valve of the air filter and the air filter provided by the invention, the shell is provided with the drain pipe, and the sealing washer is rotatably connected with the water outlet of the drain pipe by virtue of a swivel pin, so that poor air is prevented from being sucked into the air filter at the starting moment of an engine, sealing of the drain valve is realized, and furthermore liquid in the air filter can be thoroughly discharged.
Description
Technical field
The present invention relates to automobile technical field, more particularly, to a kind of air filter drain valve and air filter.
Background technology
Lower casing body position in air filter, it usually needs design discharge outlet, to discharge impurity.
Fig. 1 is the structural representation of the air filter being designed with discharge outlet in prior art, as shown in figure 1, discharge outlet setting
In the side of air filter housing 1, discharge outlet is provided with packing ring 2, and moving up and down by packing ring 2, to realize sealing or to arrange
Water.Specifically, during electromotor starting, one negative pressure of gas handling system can be continuously available to, packing ring 2 is inhaled by negative pressure
Power and discharge outlet fit tightly formation sealing；When engine stop operating, the negative pressure in gas handling system disappears, and packing ring 2 is subject to certainly
The gravity of weight and the water being deposited on discharge outlet position sinks, and gap and discharge outlet between, so that water is flowed out.
Because discharge outlet is arranged on air filter housing 1, and draining needs aperture generally large, leads to engine start wink
Between and before forming certain negative pressure, cannot fully seal between packing ring 2 and osculum, lead to enter in engine start moment empty
The air quality of filter is poor.Additionally, in order to ensure discharge outlet sealing, discharge outlet is only capable of being arranged on the side of housing 1, and this also makes
Discharge outlet and housing 1 bottom can retain larger gap, lead to the liquid of air filter bottom can not thoroughly to discharge.

Specific embodiment
Embodiments of the invention are described below in detail, the example of described embodiment is shown in the drawings, wherein from start to finish
The element that same or similar label represents same or similar element or has same or like function.Below with reference to attached
The embodiment of figure description is exemplary, is only used for explaining the present invention, and is not construed as limiting the claims.
Fig. 2 is the structural representation of air filter drain valve provided in an embodiment of the present invention.
As shown in Fig. 2 embodiments providing a kind of air filter drain valve, including drain pipe and seal washer 400；
Wherein, drain pipe fixation is located on the housing 100 of air filter；Drain pipe includes, into water section 200 and water exit end 300, entering water section
It is provided with water inlet 210 on 200, maintain gap between water inlet 210 and housing 100, water exit end 300 is provided with outlet
310, outlet 310 is provided with oblique section, the setting that faces up of cutting sth. askew；Seal washer 400 is rotatably connected on outlet 310.
Air filter drain valve provided in an embodiment of the present invention in its actual application, when the engine starts, by send out
The effect of the negative pressure that motivation provides, seal washer 400 is attracted on the oblique section of outlet 310, thus preventing sky inferior
Gas enters air filter；When a certain amount of water of accumulation in housing 100, engine stop operates, and negative pressure disappears simultaneously, row valve
Start draining, specifically, siphonic effect can be produced by drain pipe provided in an embodiment of the present invention, make the water in housing 100
Position drops to the extreme lower position of water inlet 210, thus the water in housing 100 is thoroughly discharged；Set simultaneously as cutting sth. askew and facing up
Put, thus seal washer 400 can by the action of gravity of itself, be pressed on completely on outlet 310 it is achieved that air filter quiet
State seals.
Further, for the ease of processing, ensure water exit end 300, the sealing entering between water section 200 and housing 100 simultaneously,
Entering water section 200 with water exit end 300 and housing 100 can be injection mo(u)lding.
Further, entering water section 200 is u shape, becomes obtuse angle between water exit end 300 and the straight line portion entering water section 200, thus
Residual liquid in drain pipe can be prevented, realize thoroughly discharging the liquid in housing 100, also ensure that siphonic process normally enters simultaneously
OK.

Further, referring concurrently to Fig. 3 and Fig. 4, seal washer 400 is arranged and ships and resell on another market 410, outlet 310 sets
It is equipped with groove 311, seal washer 400 is rotatably connected on outlet 310 by the cooperation of ship and resell on another market 410 and groove 311, thus can
During realizing there is negative pressure in systems, seal washer 400 can be fitted with outlet 310 around 410 rotations of shipping and reselling on another market, and is passing through
During drain pipe draining, seal washer 400 can be rotated to an angle by the thrust of water, thus producing and between outlet 310
Gap, realizes discharging water；And at the end of draining, seal washer 400 is fitted in water outlet again by the effect of self gravitation
On mouth 310, realize sealing.
It should be noted that in order to ensure that seal washer 400 itself has sufficiently large gravity and pliability, to realize existing
Air filter can fully seal outlet 310 when static, and the material of seal washer 400 can be rubber.
It is understood that because the oblique section of outlet 310 is ellipse, in order to ensure that seal washer 400 can be complete
Hermetically sealed outlet 310, seal washer 400 can also be ellipse, and the physical dimension of seal washer 400 is more than oblique section
Physical dimension.
The embodiment of the present invention additionally provides a kind of air filter, and including housing 100, wherein, this air filter also includes the present invention
The air filter drain valve that embodiment provides, this air filter drain valve is arranged on the bottom of described housing 100.
Air filter drain valve provided in an embodiment of the present invention and air filter, by arranging drain pipe on housing, make simultaneously
Seal washer is passed through to ship and resell on another market to be rotated with the outlet of drain pipe and is connected it is therefore prevented that sucking air inferior in engine start moment
Air filter, it is achieved that sealing to drain valve, also achieves simultaneously and thoroughly discharges the liquid in air filter.
Construction, feature and the action effect of the present invention, above institute are described in detail above according to the embodiment shown in schema
State only presently preferred embodiments of the present invention, but the present invention is not to limit practical range, every structure according to the present invention shown in drawing
