Vertical fan grille and vertical fan

Abstract

A fan guard is disclosed to address the problems of bulky size and time-consuming, cumbersome handling of conventional industrial fans. The system comprises: two support frame assemblies positioned opposite each other along a rotation axis; each support frame assembly having a fixing member and several extending ribs, each extending rib having a first end and a second end opposite to each other, the first end being connected to the fixing member; and several mesh components, including several first mesh components and several second mesh components. Each first mesh component is detachably connected between adjacent two extending ribs, and the several second mesh components are detachably connected between the two support frame assemblies. The mesh components surround to form a space. This invention also relates to a vertical fan. This improves ease of use.

Claims

1. A vertical fan grille, comprising: two support frame assemblies, the two support frame assemblies being opposite each other at a rotation axis, each of the two support frame assemblies having a fixing member and a plurality of extending ribs, each of the extending ribs having a first end and a second end opposite to each other, the first end being connected to the fixing member; and a plurality of mesh members, having a plurality of first mesh members and a plurality of second mesh members, each of the first mesh members being detachably connected between adjacent two extending ribs, the plurality of second mesh members being detachably connected between the two support frame assemblies, the plurality of mesh members surrounding to form a space.

2. As in request item 1, the vertical fan grille, wherein, Each of the extended ribs has two connecting grooves between the first end and the second end, and each connecting groove extends in the direction of the first end and the second end, and each of the first mesh members is connected to the two connecting grooves.

3. As in request item 2, the vertical fan grille, wherein, Each of the first mesh components has two side segments, one end of which is connected by an arc segment, and the two side segments are respectively connected to the connecting grooves of two adjacent extended ribs.

4. As in request item 3, the vertical fan grille, wherein, Each of the connecting grooves has a connecting portion, the connecting portion has a groove, the groove extends toward the first end and the second end, and the two sides of the groove have a first shoulder and a second shoulder respectively, and the edge segment is accommodated in the groove of the connecting portion.

5. As in request item 4, the vertical fan grille, wherein, The groove has several first fixing holes, and a fastener is attached to the first fixing holes to clamp the edge segment into the groove by means of the fastener.

6. As in request item 5, the vertical fan grille, wherein, A gasket is provided between the fastener and the joint, and the gasket presses against the edge segment and the first shoulder.

7. As in request item 5, the vertical fan grille, wherein, The first distance from the bottom of the groove to the first shoulder is equal to the diameter of the edge segment.

8. As in request item 5, the vertical fan cover, wherein, The second distance from the bottom of the groove to the second shoulder is less than the diameter of the edge segment.

9. As in request item 1, the vertical fan grille, wherein, Each of the first mesh components has two side segments, one end of which is connected by an arc segment. The plurality of second mesh components surround the two support frame groups in the circumferential direction along the arc segments of each of the first mesh components.

10. As requested in item 9, the vertical fan grille, wherein, Each of the second mesh components has two sets of arc lines, and each set of arc lines has an arc degree corresponding to the arc segment of the first mesh component.

11. As in request item 10, the vertical fan grille, wherein, Each of the arc groups has a first line segment and a second line segment arranged side by side, and each of the second mesh members is connected to a second fixing hole at the second end of each of the extended ribs by means of a fastener that passes through the first line segment and the second line segment.

12. As in request item 11, the vertical fan grille, wherein, The second fixing hole forms a non-closed circle at the cross-section of the extending rib.

13. As in request item 10, the vertical fan grille, wherein, The first mesh element has an arc segment with at least one connecting hole. Each arc group has a first line segment and a second line segment arranged side by side. The at least one connecting hole of the arc segment is located between the first line segment and the second line segment. A fastener passes between the first line segment and the second line segment to engage with the at least one connecting hole.

14. A standing fan comprising: a motor; a plurality of fan blades; and a fan guard as claimed in any one of claims 1 to 13, wherein the plurality of fan blades are located within the space, and the motor drives the plurality of fan blades to rotate within the space relative to the axis of rotation.

15. As in request item 14, the vertical fan, wherein, The vertical fan has several rollers, which are connected to the second end of each of the extended ribs by several connecting brackets.
