Description

A kind of integral-type air filter

Technical field

The utility model relates to a kind of air filter, especially a kind of integral-type air filter.

Background technique

Currently, application scenarios, terminal are more and more extensive for put-put, such as road cutting machine, mini-tiller It is also more and more severe Deng, the environment of use process；Since there are many impurity, when engine operation, piston is to moving down in air It moves and forms negative pressure in cylinder for outside air by air intake duct sucking, with the passage for using the time, depend merely on filter element filtering very The fatal problems such as filter core blocking, scuffing of cylinder bore are easy to cause, while the filter element replacing period is shorter, higher cost.

For the impurity crossed in air filtering, while extending the service life of filter element replacing period and complete machine, partial engine It is filtered using cyclone centrifugal power and filter core, but due to air filtering device structure factor, at filter air inlet about Only 90 ° of stroke has spirally-guided effect, and the air of sucking is more at random, is not effectively formed flow velocity and revolves faster General mood stream will effectively cannot be separated in heavier foreign substances from air.

Utility model content

The purpose of this utility model is just to provide a kind of integral-type air filter that can efficiently separate impurity in air.

The purpose of this utility model is that technical solution in this way is realized, a kind of integral-type air filter, including Pedestal, end face is provided with the shell connecting with pedestal on the base, filter core is vertically arranged in the housing cavity, in institute It states housing exterior walls upper and lower part and is respectively arranged with the air inlet and ash discharging hole being connected to housing cavity, on the housing exterior walls It is provided with the thread protrusion that housing exterior walls lower part is extended to along housing exterior walls top, which makes inner walls form connection Air inlet to ash discharging hole screw thread air flue.

It further describes, the thread protrusion has upper end inclined-plane disposed in parallel and lower end inclined-plane, the upper end inclined-plane Constituting inner walls with lower end surface inclined-plane influences the screw thread air flue of air flow direction.

It further describes, in order to adapt to different operating environment and job requirements, the air inlet or/and ash discharging hole are located at shell In the first quartile of body horizontal cross-section, the second quadrant, third quadrant or/and fourth quadrant.

Eddy flow is quickly formed in shell in order to guide air to enter, the air inlet is arranged in the upper housing and passes through Air inlet pipe is connect along housing exterior walls tangential direction with shell.

Ash discharging hole air inlet influences ash discharge in order to prevent, and the outlet of the ash discharging hole is arranged obliquely.

By adopting the above-described technical solution, the utility model has smart structural design, using reliable and stable, reaction is fast Advantage fast, low in cost can efficiently separate the impurity in air using it, greatly improve filter effect, extend filter The service life and maintenance time of core make more to clean into in-engine air, and complete machine service life is extended.

Specific embodiment

Specific embodiment of the present utility model is described in further detail with reference to the accompanying drawing, but the utility model These embodiments are not limited to, any improvement or substitution on the present embodiment essence spirit still falls within the utility model Claim range claimed.

Embodiment 1: as shown in Figure 1, a kind of integral-type air filter, including pedestal 1, it is set in 1 upper surface of pedestal It is equipped with the shell 2 connecting with pedestal 1, is vertically arranged with filter core 3 in 2 inner cavity of shell, on the 2 outer wall top of shell under Portion is respectively arranged with the air inlet 4 and ash discharging hole 5 being connected to 2 inner cavity of shell, is provided on 2 outer wall of shell along shell 2 Outer wall top extends to the thread protrusion 6 of 2 outer wall lower part of shell, which makes 2 inner wall of shell form connection air inlet 4 To the screw thread air flue 7 of ash discharging hole 5.

It further describes, the thread protrusion 6 has upper end inclined-plane 8 disposed in parallel and lower end inclined-plane 9, and the upper end is oblique Face 8 and lower end surface inclined-plane 9, which constitute 2 inner wall of shell, influences the screw thread air flue 7 of air flow direction.

As shown in Fig. 2,3,4,5,6,7,8,9, the air inlet 4 or/and ash discharging hole 5 are located at the of 2 horizontal cross-section of shell In one quadrant, the second quadrant, third quadrant or/and fourth quadrant.

Eddy flow is quickly formed in shell in order to guide air to enter, the setting of air inlet 4 is on 2 top of shell and leads to It crosses air inlet pipe 11 and is connect along 2 outer wall tangential direction of shell with shell 2.

For the ease of smoothly excluding dust, the outlet of the ash discharging hole 5 is arranged obliquely.

When the engine is running, air and impurity are inhaled into, and air enters air inlet 4 and is accelerated, then high speed along Helical intake 7 on 2 inner wall of shell carries out mandatory high-speed screw rotary motion, and the rotary motion of air-flow high-speed screw can be by weight Impurity bigger than normal is acted on outside " getting rid of " to air-flow by gravity, rotary centrifugal force, and is taken to ash discharging hole 5 by spiral air flow and be discharged, The helical intake 7 that spiral salient 6 is formed is connected to air inlet 4 and ash discharging hole 5, and flow spiral path is shorter and unimpeded, air-flow stream Speed decays smaller from air inlet 4 to ash discharging hole 5, and air-flow is in spiral course, and centrifugal force attenuation degree that impurity is subject to weakens, more More impurity can be gone out by whirlwind " getting rid of ", filter effect more preferably, and carry out the air after cyclonic filter can by filter core 3 absorb go forward side by side Row refined filtration eventually enters into inlet channel 10 by engine " sucking ".In the present invention, the air inlet 4 and ash discharging hole 5 Be arbitrarily arranged at one respectively, two, three, can be achieved above-mentioned leaching effect in four-quadrant region, user can according to the actual situation Inlet and outlet mouth with different directions, while the path length of adjustable helical intake.
