In certain embodiments, the filter core layer is replaceably disposed within the filter screen cover.

In some embodiments, the filter screen cover comprises a mesh outer cover, an intra-mesh pressure layer arranged on the inner side of the mesh outer cover, and a fixing ring pressed and fixed on the sides of the mesh outer cover and the intra-mesh pressure layer, and the filter core layer is clamped between the mesh outer cover and the intra-mesh pressure layer.

In some embodiments, the box body and the filter screen cover are fixedly connected through a buckle connection or a screw.

In some embodiments, the back of the box body is sleeved on an air inlet of the fan, the air filtering box further comprises a fixing support covered on the rear side of the fan, the fan is firmly fixed between the box body and the fixing support, and the back of the box body is fixedly connected with the fixing support through a buckle or a screw.

In certain embodiments, the filter cover is secured to the front face of the case.

Compared with the prior art, the utility model has the following beneficial effects: the utility model provides a fan structure of a fuel cell, which increases the air inlet cavity space by adding a structural member air filtering box, adopts a large-area filter screen cover, and is provided with a filter core layer, thereby not only meeting the air filtering effect, but also meeting the air inflow of air, and not changing the structure of the fan to influence the performance parameters of the fan. Effectively avoid impurity in the air to get into fuel cell, also avoid the air flue to block up, guarantee battery efficiency, prolonged life.

Description of the embodiments

The fan structure of the fuel cell, as shown in fig. 5 and 6, comprises a fan 1 with an air inlet 11, as shown in fig. 1-5, and also comprises an air filtering box 2, wherein the air filtering box 2 comprises a box body 21 fixed on the fan 1, and a filter screen cover 22 capable of being detachably fixed on the outer side of the box body 21, a layer of filter core layer is arranged on the filter screen cover 22, and the air inlet 11 is positioned in an inner cavity formed between the box body 21 and the filter screen cover 22.

Through increasing a structure air filter box to having increased the oral cavity space of intaking, adopting the filter screen lid of large tracts of land, set up the filter core layer on the filter screen lid, thereby can satisfy the filterable effect of air, can satisfy the air input of air again, and can not change the performance parameter that fan own structure influences the fan. Effectively avoid impurity in the air to get into fuel cell, also avoid the air flue to block up, guaranteed battery efficiency, prolonged life, filter screen lid detachable construction, the filter core layer can be changed the ground and set up in filter screen lid 22.

In detail, as shown in fig. 1 to 4, the case 21 is connected to the filter cover 22 by screws. The filter cover 22 includes a mesh outer cover 22a, an intra-mesh pressure layer 22b provided inside the mesh outer cover 22a, and a fixing ring 22c pressed and fixed on the sides of the mesh outer cover 22a and the intra-mesh pressure layer 22b, and a filter core layer is sandwiched between the mesh outer cover 22a and the intra-mesh pressure layer 22 b. The filter core layer is not shown in the figure.

When the filter core layer in the air filter box is dirty for a long time or used in different air environments, the whole air filter box does not need to be replaced, and the filter screen cover 22 is only required to be detached and detached to be replaced or the filter core layer made of materials suitable for the air environments can be used, so that a good filtering effect can be achieved, and the cost is reduced.
