Description

Air outlet cover and fan

Technical Field

The application relates to the technical field of household appliances, in particular to an air outlet cover and a fan.

Background

The air outlet cover is an important part on the fan, can prevent the body parts such as fingers of a user from contacting the rotating fan blades to cause accidents, protects the fan blades from being damaged due to collision of foreign objects, and can play a role in guiding air outlet of the fan blades.

In the air outlet cover in the prior art, a plurality of radial ribs are distributed in a radial mode in a conventional design, and one circle or a plurality of circles of concentric circular ribs are additionally arranged at the tail ends of the radial ribs so as to achieve an encryption effect and prevent overlarge gaps of the air outlet cover. However, the added concentric ribs can enclose the air outlet ring to form a bundling effect, so that the spiral natural wind feeling is destroyed, and the user feels poor.

SUMMERY OF THE UTILITY MODEL

The application provides an air outlet cover can reach the effect of encrypting little air outlet cover clearance through the radial rib that adopts Y shape, and then avoids adopting the air outlet cover design of concentric circles rib, can reduce the effect of bunching of air outlet cover to the air-out, has solved user's body and has felt not good technical problem in prior art.

In order to solve the problems, the application provides an air outlet cover which comprises an outer peripheral frame, a central piece and radial ribs.

The center piece is located in the middle of the outer peripheral frame. The plurality of radial ribs are spirally distributed and connected between the peripheral frame and the central piece, and the radial ribs are Y-shaped structures, and one bifurcated end faces the peripheral frame.

In the prior art, in order to avoid too large gap of the air outlet cover and prevent fingers of a user from entering, one circle or a plurality of circles of concentric circular ribs are additionally arranged on the periphery of the radial ribs in the radial direction, but the wind is enclosed, and the natural wind feeling of spiral design is damaged although the wind is bundled. Reversely observing the air outlet cover in the application, the plurality of Y-shaped radial ribs are distributed spirally and connected between the peripheral frame and the central piece, so that the gap width can be controlled no matter the radial ribs are close to the center or the outer edge, a user can be prevented from stretching fingers into the air outlet cover, and the air outlet cover has better safety protection particularly for users with small ages; in addition, avoid using concentric circles rib and enclose wind, the heliciform that the radial rib of heliciform distribution can strengthen the helicity of wind, makes the user produce the wind and is the body sense of "gust blows" and just as outdoor natural wind, and the user has splendid body sense when using, especially uses indoor can be comfortable especially, seems to be put in nature.

In a possible design, the radial rib includes a first rib and a second rib both in a circular arc shape, both ends of the first rib are respectively connected to the outer peripheral frame and the center piece, and both ends of the second rib are respectively connected to the first rib and the outer peripheral frame.
