The specific structure of the anti-clogging structure according to the embodiment of the present invention is described below with reference to fig. 1 to 2.
As shown in fig. 1-2, fig. 1 discloses an anti-clogging structure, a housing 100 defines a containing cavity, a filter element 110 is arranged in the housing 100, a gap is formed between a top wall of the filter element 110 and a top wall of the containing cavity, a vent hole 120 is formed in the top wall of the filter element 110, and the anti-clogging structure comprises a conical support frame 1 and a filter screen 2. Conical support frame 1 establishes on the roof of filter core 110 and butt in the roof that holds the chamber, and conical support frame 1 cover is established on exhaust hole 120, is equipped with a plurality of intercommunication mouths on conical support frame 1's global. The filter screen 2 is arranged around the periphery of the conical support frame 1, and the cross-sectional area of the filter screen 2 is reduced in the direction approaching the filter element 110.
It can be understood that, because 1 cover of toper support frame is established on exhaust hole 120, filter screen 2 encloses simultaneously and establishes on 1 global of toper support frame to make the pollutant in the fuel can't pass through the intercommunication mouth and get into exhaust hole 120 on, make prevent blockking up the structure and can play better isolated effect to the particle pollutant in the fuel, ensured exhaust hole 120's smooth and easy use. Simultaneously, because the cross sectional area of filter screen 2 reduces in the direction that is close filter core 110, even when the fuel is holding the intracavity circulation, make the particulate matter attach to filter screen 2 on, the particulate matter also can fall under its self action of gravity and break away from filter screen 2 by oneself to can keep filter screen 2 long-time unblocked, need not additionally to set up other structures in order to clear away the particulate matter on filter screen 2, the clearance frequency of preventing blockking up the structure has been reduced, and then the dismouting frequency of casing 100 has been reduced.
According to the anti-clogging structure of this embodiment, can effectively filter the particulate pollutant in the fuel, prevent that the particulate pollutant in the fuel from blockking up exhaust hole 120 of filter core 110, particulate matter on the filter screen 2 can break away from filter screen 2 by oneself under the effect of self gravity simultaneously, make filter screen 2 can keep long-time unblocked and better filter effect, thereby effectively reduced the clearance frequency who prevents blockking up the structure, reduce the fault phenomenon that filter core 110 blockked up and lead to, the life of filter core 110 has been prolonged, user's use experience has been improved.
In some embodiments, as shown in fig. 1 and 2, the conical support frame 1 comprises a first support frame 11, a second support frame 12 and a plurality of connecting spokes 13. The first support frame 11 is arranged on the top wall of the accommodating cavity. The second support frame 12 is disposed on the top wall of the filter element 110, and the outer diameter of the second support frame 12 is smaller than that of the first support frame 11. A plurality of web spokes 13 distribute in the circumferential direction of first support frame 11 in order to form a plurality of intercommunication mouths, and a plurality of web spokes 13's one end all is connected with first support frame 11, and the other end all is connected with second support frame 12.
It can be understood that, first support frame 11 and second support frame 12 can play firm supporting role to a plurality of web spokes 13 and filter screen 2, make and establish the difficult deformation phenomenon that appears of anti-clogging structure on filter core 110, make anti-clogging structure still can play better anti-clogging effect to the exhaust hole 120 that is located wherein in long-term use, a plurality of web spokes 13 can be convenient for form a plurality of intercommunication mouths on toper support frame 1 to the circulation in preventing blockking up the structure of fuel.
In some embodiments, the first support bracket 11 and the second support bracket 12 each comprise an oil resistant elastomer.
It can be understood that the oil-resistant elastic piece has both elastic performance and oil resistance, and the oil resistance can ensure that the anti-clogging structure still keeps reliable strength in the process of filtering fuel for a long time, so that the service life of the anti-clogging structure is prolonged, and the replacement frequency of the anti-clogging structure is reduced. When the elastic performance can make the toper support frame 1 install between filter element 110 and casing 100, first support frame 11 and second support frame 12 play the elasticity respectively and compress tightly the effect to filter element 110 and casing 100, because the position of filter element 110 and casing 100 is fixed usually, thereby make first support frame 11 and second support frame 12 all can establish firmly between filter element 110 and casing 100, thereby need not to set up other fixed knot that are used for fixed anti-clogging structure on filter element 110 and casing 100 and construct, improved the application scope who prevents the clogging structure.
Illustratively, the oil resistant elastomer is made from an oil resistant TPU elastomer. Of course, in other embodiments of the present invention, the oil-resistant elastic member may be made of other materials, which need not be described herein.
