Problems solved by technology

[0004] The disadvantage of the prior art is that the dust discharge valve 3 protrudes from the air filter housing. When the vehicle is assembled, if the dust discharge valve faces the outside of the frame, it may interfere with the side protection. If it faces other directions, it may cause interference with other parts. The gap is too small or interferes; the cooperation between the dust discharge valve and the dust discharge valve interface is fixed by a convex structure, the inner diameter of the upper end of the dust discharge valve is small, and it is difficult to assemble; the dust discharge valve can only reduce the air filter suction by reducing the outlet size The amount of air in the lower place cannot effectively prevent the occurrence of this problem, and the outlet size is too small will cause the air filter to discharge dust and drainage is not smooth, so the selection of the outlet 4 size of the dust discharge valve is more complicated

Embodiment Construction

[0031] The technical solutions of the present invention are described below through specific examples. The following examples are only exemplary, and can only be used to explain and illustrate the technical solutions of the present invention, and cannot be interpreted as limitations to the technical solutions of the present invention.

[0032] Such as Figure 4 to Figure 6 As shown, the dust discharge valve of the present invention includes a valve core 7 and a valve body 6, which are composed of a disc and a ring of bosses 10 below it; the valve core 7 is composed of a valve stem 8 and an arc surface structure 9 connected thereto, The valve stem 8 is arranged on the center of the arc surface structure 9;

[0033] The valve stem 8 is made of an upper cylinder 12, a lower cylinder 13 and a truncated cone 14 in the middle; the diameter of the upper cylinder 12 is smaller than the diameter of the lower cylinder 13. The lower cylinder 13 is provided with a groove 15, and the diam...

Abstract

The invention relates to an automotive dust discharge valve. The automotive dust discharge valve comprises a valve core and a valve body, wherein the valve body is formed by a disk and a circle of bosses below the disk, the valve core is formed by a valve rod and a cambered surface structure connected with the valve rod, the valve rod is arranged at the center of the cambered surface structure, the valve rod is formed by an upper cylinder, a lower cylinder and a middle circular cone, the diameter of the upper cylinder is less than the diameter of the lower cylinder, and a circle of grooves are formed in the lower cylinder. The automotive dust discharge valve prevents defects generated when an air filter is arranged, and is prevented from protruding out of a housing of the air filter by forming a dust discharge valve interface in the lower end of the air filter, and therefore the problem that an interval between the dust discharge valve and each surrounding part is undersized or the dust discharge valve interferes with the surrounding parts is prevented.

Description

technical field [0001] The invention belongs to the field of auto parts, in particular to a dust discharge valve mounted on an air filter of an automobile. Background technique [0002] The dust discharge valve is an important component of the air filter, which is used to filter out impurities and moisture in the intake system of the air filter. With a dust discharge valve with good performance, impurities and moisture can be discharged from the air filter in time without affecting the normal use of the air filter; with a dust discharge valve with poor performance, impurities and moisture cannot be discharged smoothly, such as slow discharge or insufficient discharge. Thoroughly, especially in rainy days, will lead to serious water accumulation in the air filter, which will greatly reduce the service life of the filter element. Therefore, the performance of the dust discharge valve will directly affect the service life of the air filter and the power, economy and emission pe...
