Abstract

The utility model discloses a bladeless fan which comprises a base arranged at the bottom, a hollow lower strut, a hollow upper strut movably arranged on the lower strut, a hollow bracket arranged on the upper strut and a hollow vane articulated with the bracket, wherein the inner cavities of the lower strut, the upper strut, the bracket and the vane are communicated. In the utility model, an air supply angle can be rotated at will according to the demand of a user and the utilization rate of the supplied air is high; and the bladeless fan is simple in structure, convenient for use and beneficial to popularization.

Description

A kind of no blade fan

Technical field

The utility model relates to a kind of fan, is specifically related to a kind of no blade fan.

Background technique

Traditional fan all is the high speed rotating that utilize blade, drives air flows, and structure is comparatively complicated, and air quantity is less.

At the defective of conventional fan, people have developed no blade fan, and it mainly is to utilize motor and compression set to grow to press air-treatment to become high-pressure air, discharges by being opened in fan outlet (being generally the fine gap on the vane) again; This fan structure is simple, and is easy to operate, has bright development prospect.

Yet, existing no blade fan, its air-out angle is difficult for regulating, and only can blow according to single direction, and the utilization ratio of sending wind is lower.

In sum, develop a kind of no blade fan that can the regulated at will angle, become the focus of paying close attention in the industry.

Summary of the invention

At the deficiencies in the prior art, the purpose of this utility model is intended to provide a kind of no blade fan, and it can arbitrarily rotate the output angle of wind as required.

For achieving the above object, the utility model adopts following technological scheme:

A kind of no blade fan comprises the base that is positioned at its bottom and is installed in the bottom and the lower posts of hollow, is movably arranged on the described lower posts and the upper strut of hollow, is installed on the described upper strut and the support of hollow and with described support pivot dress and deploy empty vane; The mutual conducting of the inner chamber of described lower posts, upper strut, support and vane.

Described vane is rounded, and described support takes the shape of the letter U.

The inboard, U-shaped two upper end portion of described support is respectively arranged with pivot, and described vane is installed on the described pivot.

The outside of described lower posts and described upper strut joint also is set with one and can locks its two outer button.

Described lower posts is rotating to be connected on the described base.

The no blade fan that the utility model is set forth, its beneficial effect is:

1, can be according to using needs, random rotation wind direction is sent the utilization ratio height of wind;

2, simple in structure, easy to use, help promoting.

Fig. 1 is a kind of structural representation that does not have blade fan of the utility model;

Fig. 2 is the A place zoomed-in view of Fig. 1.

Embodiment

Below, in conjunction with the accompanying drawings and embodiment, no blade fan of the present utility model is described further, so that clearerly understand the utility model technological thought required for protection.

As shown in Figure 1, 2, be a kind of no blade fan of the present utility model, comprise base 1, lower posts 2, upper strut 3, support 4, vane 5, it is hollow structure, and lower posts 2 is connected on the base 1, and can be along its rotational, upper strut 3 is inserted in the lower posts 2, can slide up and down with respect to lower posts 2, and support 4 takes the shape of the letter U substantially, its bottom is inserted into the upper end of upper strut 3, and can be around the rotational of upper strut 3.Vane 5 is a toroidal, is installed in the U-shaped of support 4, and concrete is, is respectively arranged with the pivot 41 that extends internally in the inboard, U-shaped two upper end portion of support 4, and default and pivot 41 installation holes for matching positions on the vane 5 make that vane 5 can be around the rotational of pivot 41.

The above-mentioned mutual conducting of internal cavities that comprises base 1, lower posts 2, upper strut 3, support 4, vane 5; Pivot 41 is a hollow structure, is used for the inner chamber of conducting vane 5 and support 4.

For a person skilled in the art, can make other various corresponding changes and distortion, and these all changes and distortion should belong within the protection domain of the utility model claim all according to technological scheme described above and design.

Claims (5)

1. no blade fan, it is characterized in that, comprise the base that is positioned at its bottom and be installed in the bottom and the lower posts of hollow, be movably arranged on the described lower posts and the upper strut of hollow, be installed on the described upper strut and the support of hollow and with described support pivot dress and deploy empty vane; The mutual conducting of the inner chamber of described lower posts, upper strut, support and vane.

2. no blade fan as claimed in claim 1 is characterized in that described vane is rounded, and described support takes the shape of the letter U.
