Abstract
The utility model provides a self-cleaning type air filter which comprises an air filter shell and a filter element arranged in an inner cavity of the air filter shell. The filter element divides the inner cavity of the air filter shell into an upper air chamber and a lower air chamber. An upper air inlet passageway is arranged on the top of the upper air chamber, a lower air inlet passageway is arranged at the bottom of the lower air chamber, a side air inlet passageway is arranged on the lower air chamber and connected with a small air storage tank, an air pump and an inflation valve are further arranged on the side air inlet passageway, a decompression valve is arranged below the small air storage tank, an exhaust passageway used for being connected with the lower air inlet passageway is arranged on the decompression valve, a pressure sensor, the exhaust pump, the inflation valve and the decompression valve are connected with a cleaning controller through wires, and a throttle valve used for controlling the lower air inlet passageway to be opened and closed is arranged in the lower air inlet passageway. According to the self-cleaning type air filter, cleaning is completed under the control of the cleaning controller without manual intervention, the filter element can be comprehensively cleaned without leaving dead corners, the situation that air inlet efficiency is influenced when too much dust is accumulated on the filter element can be avoided, and meanwhile the service life of the air filter element can be prolonged.
Description
Technical field
The utility model relates to a kind of self-cleaning air filter.
Background technique
In prior art, if Chinese notice of authorization number is the blow back self-cleaning air cleaner described in the document of CN2707988Y, because its puff prot is less and be positioned at fixed position on air jet pipe, can not clean the whole surface of filter core, poor to the cleaning effect of air filtering core; If Chinese notice of authorization number is the self-cleaning air filter described in the document of CN102140981A, puff prot position on its spiral air jet pipe 6 is fixed, although puff prot can clean the surface of circular filter core when air jet pipe rotation, but only have the corresponding cartridge surface energy in puff prot position cleaned, all the other position cleaning effects are poor.
Model utility content
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, a kind of self-cleaning air filter is provided, can clean the surface of filter core comprehensively, do not stay dead angle.
The utility model solves the technological scheme that its technical problem adopts: a kind of self-cleaning air filter, comprise air cleaner casing and the filter core that is arranged on air cleaner casing inner chamber, the inner chamber of air cleaner casing is separated into upper gas chamber and lower chamber by filter core, the top of upper gas chamber is provided with enterprising air flue, the bottom of lower chamber is provided with lower intake duct, on lower chamber, be provided with side intake duct, side intake duct is connected with small gas storage tank, on side intake duct, be also provided with air exhauster and gas charging valve, the below of small gas storage tank is provided with Decompression valves, on Decompression valves, be provided with the air outlet flue for connecting lower intake duct.
Further, the top of small gas storage tank is provided with pressure transducer, and pressure transducer, air exhauster, gas charging valve and Decompression valves are connected with clean controller by being connected wire respectively.
Further, in lower intake duct, be provided with and control lower intake duct conducting and closed closure.
The beneficial effects of the utility model are: self-cleaning air filter of the present utility model, completed by clean controller control, without manual intervention, can clean filter core comprehensively, do not stay dead angle, can prevent that filter core dust stratification from affecting intake efficiency too much, can extend the working life of air filtering core simultaneously.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Wherein: 1, air cleaner casing, 2, enterprising air flue, 3, filter core, 4, closure, 5, lower intake duct, 6, air exhauster, 7, gas charging valve, 8, small gas storage tank, 9, pressure transducer, 10, Decompression valves, 11, side intake duct, 12, air outlet flue, 13, clean controller.
Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with the utility model.
A kind of self-cleaning air filter as shown in Figure 1, comprise air cleaner casing 1 and the filter core 3 that is arranged on air cleaner casing 1 inner chamber, the inner chamber of air cleaner casing 1 is separated into upper gas chamber and lower chamber by filter core 3, the top of upper gas chamber is provided with enterprising air flue 2, the bottom of lower chamber is provided with lower intake duct 5, on lower chamber, be provided with side intake duct 11, side intake duct 11 is connected with small gas storage tank 8, on side intake duct 11, be also provided with air exhauster 6 and gas charging valve 7, the below of small gas storage tank 8 is provided with Decompression valves 10, on Decompression valves 10, be provided with the air outlet flue 12 for connecting lower intake duct 5, the top of small gas storage tank 8 is provided with pressure transducer 9, pressure transducer 9, air exhauster 6, gas charging valve 7 is connected with clean controller 13 by being connected wire respectively with Decompression valves 10, in lower intake duct 5, be provided with and control lower intake duct 5 conductings and closed closure 4.
When motor is during in idling mode, first clean controller 13 is opened gas charging valve 7 and is allowed air exhauster 6 work, ambient air is pressed into small gas storage tank 8 after by the filter core 3 in air-strainer, reach after setting value when clean controller 13 records small gas storage tank 8 internal air pressures by pressure transducer 9, close air exhauster 6 and gas charging valve 7; In the time that motor is not worked, closure 4 is in closed condition, Decompression valves 10 is unlocked after controlling, pressurized gas reverse flow in small gas storage tank 8 is through filter core 3, then enter atmosphere by enterprising air flue 2, dust and impurity that can be with being adsorbed in until then in filter core 3 upper surfaces and filter core 3 at the mobile gas of this process high speed, thereby filter core 3 is cleaned, on this clean controller, be also provided with switch, after opening, after engine misses, just automatically perform above-mentioned cleaning course, if closing switch is cancelled this function.
Take above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, relevant staff can, not departing from the scope of this model utility technological thought, carry out various change and modification completely.The technical scope of this model utility is not limited to the content on specification, must determine its technical scope according to claim scope.
