Abstract
The utility model discloses a two refill air cleaner, including frame and first refill, first refill is installed on the terminal surface of frame, still installs the second refill on the terminal surface of frame, the parallel arrangement that is of first refill and second refill, and the frame is square frame shape, is provided with the baffle between first refill and second refill, and this baffle is installed in the frame, is provided with the protecting wire net on the terminal surface of first refill and second refill respectively, and the hole of frame is plugged up through first refill and second refill shutoff. Make first refill adhere to the dust of certain degree after, can carry out filtration through the second refill to guaranteed the normal filtration circulation of air, made the engine can keep normal operation, improved air cleaner's life, brought sufficient time for changing air cleaner simultaneously.
Description
Technical Field
The utility model relates to an air cleaner on the motor vehicle, concretely relates to two refill air cleaners.
Background
When the engine is in operation, a large amount of air needs to be sucked, and if the air is not filtered, dust suspended in the air is sucked into the cylinder, so that the abrasion of the piston group and the cylinder is accelerated. Larger particles enter between the piston and the cylinder, causing severe "scuffing" phenomena, which is particularly severe in dry, sandy working environments. The air filter is arranged in front of the carburetor or the air inlet pipe, plays a role in filtering dust and sand grains in air and ensures that sufficient and clean air enters the air cylinder.
The general air filter has only one paper core, and when dust is attached to the paper core, the paper core cannot effectively filter air, so that the air cannot circulate, and the performance of an engine is affected.
Disclosure of Invention
In order to solve the above problem, an object of the present invention is to provide a double-refill air filter, which can start another refill to filter when a refill can not filter air normally, so as to prolong the normal circulation time of air and strive for enough time for replacing the air filter.
In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a two refill air cleaner, includes frame and first refill, and first refill is installed on the terminal surface of frame, still install the second refill on the terminal surface of frame, first refill with the second refill be parallel arrangement, the frame is square frame shape first refill with be provided with the baffle between the second refill, this baffle is installed in the frame first refill with be provided with the protecting wire net on the terminal surface of second refill respectively, the hole of frame passes through first refill with the second refill is plugged up.
The first paper core and the second paper core are multi-pleat filter paper, and the filtering holes of the first paper core are larger than the filtering holes of the second paper core.
The height of the second paper core is smaller than that of the first paper core.
The first paper core and the second paper core are made of synthetic fibers.
The aperture of the protective net is between 0.2cm and 0.5 cm.
The utility model discloses a this kind of structure for after first refill adheres to the dust of certain degree, can carry out filtration through the second refill, thereby guaranteed the normal filtration circulation of air, made the engine can keep normal operation, improved air cleaner's life, bring sufficient time for changing air cleaner simultaneously.
The invention is further described with reference to the accompanying drawings and the detailed description.

FIG. 1 is a side view of an embodiment of the present invention;
fig. 2 is a top view of an embodiment of the present invention.
Detailed Description
The present invention is described in detail below with reference to the following examples, which are only used for further illustration of the present invention, and should not be construed as limiting the scope of the present invention.
As shown in fig. 1 and fig. 2, the embodiment discloses a double-refill air cleaner, which comprises a frame 1 and a first refill 2, wherein the first refill 2 is installed on the end surface of the frame 1, a second refill 3 is further installed on the end surface of the frame 1, the first refill 2 and the second refill 3 are arranged in parallel, the frame 1 is in a square frame shape, a partition plate 4 is arranged between the first refill 2 and the second refill 3, the partition plate 4 is installed in the frame 1, a protection net 5 is respectively arranged on the end surfaces of the first refill 2 and the second refill 3, and an inner hole of the frame 1 is sealed by the first refill 2 and the second refill 3.
The first paper core 2 and the second paper core 3 are multi-pleat filter paper, so that more ventilation air flow channels can be formed, the filtering area and the air supply volume are increased, the air supply resistance is reduced, and the filtering holes of the first paper core 2 are larger than those of the second paper core 3, so that the first paper core 2 can be preferentially used, and the two paper cores are prevented from being blocked simultaneously.
The height of the second paper core 3 is smaller than that of the first paper core 2. Through the design, the ventilation air channel and the filtering area of the second paper core 3 are reduced relative to the first paper core 2, so that the air supply quantity is improved, and the second paper core 3 is mainly used for auxiliary filtering, so that the material cost can be reduced.
The first paper core 2 and the second paper core 3 are made of synthetic fibers. The structure can ensure that the first paper core 2 and the second paper core 3 have large dust capacity and low resistance, ensure the smoothness of ventilation and have high temperature resistance.
The aperture of the protective net 5 is between 0.2cm and 0.5 cm. By the structure, the protective net 5 can block large sundries, the utilization rate of the first paper core 2 and the second paper core 3 is improved, and the service life of the paper core is prolonged.
Adopt above-mentioned technical scheme for first refill 2 adheres to the dust of certain degree after, can carry out filtration through second refill 3, thereby has guaranteed the normal filtration circulation of air, makes the engine can keep normal operation, has improved air cleaner's life, brings sufficient time for changing air cleaner simultaneously.
