Abstract
The utility model provides a guide structure of a filter core and a blade ring. According to the technical scheme of the utility model, a guide groove is formed in the center of a bottom end cover of the filter core, a guide salient is correspondingly arranged in the center of the end surface of the blade ring, and guide is realized between the blade ring and the filter core by mutually matching of the guide salient and the guide groove. With the adoption of the guide structure, the blade ring is accurately located on the filter core; and when an air flow passes through blades of the blade ring, a gap between the blade ring and the filter core is constant, so that the blade ring can not twist, the air flow is smooth, the air inlet resistance is small, and the filtering efficiency is ensured.
Description
Technical field
The utility model relates to air filter, especially the guide frame of its filter core and blade ring.
Background technology
At present, in air filter, just bottom cover one end from filter core is enclosed within blade ring on the cylindrical of filter core, gap between blade ring and the filter core is large, and blade ring is in quick condition, when air-flow passes through the blade ring blade, easily make the blade ring twisting, the generation swirling eddy that liquidates, relatively more disorderly, cause intake resistance large.
Summary of the invention
For blade ring is accurately located with respect to filter core, avoid the blade ring twisting, the utility model proposes the guide frame of filter core and blade ring.
The technical solution of the utility model is: the guide frame of filter core and blade ring, it is characterized in that: the bottom cover center at filter core is provided with direction recess, the corresponding guide protrusions that is provided with in the end face center of blade ring cooperatively interacts by guide protrusions, direction recess between blade ring and the filter core and realizes guiding.
Beneficial effect: the utility model has been realized the accurate location of blade ring on filter core, when air-flow passes through the blade ring blade, and the clearance constant between blade ring and the filter core, blade ring can not twist, and air-flow is unobstructed, and intake resistance is little, has guaranteed filtering efficiency.
Description of drawings
Fig. 1 is structure chart of the present utility model.
The specific embodiment
Filter core as shown in Figure 1 and the guide frame of blade ring, bottom cover 3 centers at filter core 1 are provided with direction recess 3a, the corresponding guide protrusions 2b that is provided with in the end face 2a center of blade ring cooperatively interacts by guide protrusions 2b, direction recess 3a between blade ring 2 and the filter core and realizes guiding.
As shown in Figure 1, filter core is comprised of the end cap 6 of giving vent to anger, center filter screen 5, filter course 4, bottom cover 3.Because the structure of filter core is prior art, is not described in detail at this.
