SUMMERY OF THE UTILITY MODEL

In view of this, the utility model aims at providing a simple structure, less high silence wind wheel that is applicable to electric fan heater of noise.

In order to achieve the above purpose, the technical scheme of the utility model is realized like this:

the utility model provides a high silence wind wheel suitable for electric fan heater, its characterized in that, the wind wheel includes a plurality of blades, annular connecting portion and supporting part, the blade is around setting up on annular connecting portion, supporting part and annular connecting portion inner circle fixed connection, the supporting part is equipped with the pivot, annular connecting portion use the pivot to drive the blade rotation as the center.

The supporting part comprises a bottom plate and a plurality of supporting plates, the upper ends of the supporting plates are bent and connected with the bottom plate, and the lower ends of the supporting plates are connected with the inner ring of the annular connecting part.

The central position of the bottom plate is provided with a mounting hole, and a supporting block is mounted in the mounting hole.

Wherein, the blades of the wind wheel are provided with dynamic balance blocks.

Wherein, the blade of wind wheel is inwards buckled to be an arc structure.

Wherein the distance between two adjacent blades is between 3mm and 15 mm.

Compared with the prior art, high silence wind wheel suitable for electric fan heater have following advantage: the blades of the wind wheel are provided with the dynamic balance blocks, so that the wind wheel is prevented from shaking when rotating at a high speed, and noise is generated.

Detailed Description

It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict.

In addition, in the embodiments of the present invention, the directional indications (such as upper, lower, left, right, front and rear … …) are mentioned, and the directional indications are only used to explain the relative position relationship between the components, the motion situation, etc. in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indications are changed accordingly.

All directions or positional relationships mentioned in the embodiments of the present invention are positional relationships based on the drawings, and are only for convenience of description and simplified description, and do not imply or imply that the device or element referred to must have a specific orientation, and should not be construed as limiting the present invention. If there is a description in an embodiment of the present invention referring to "first", "second", etc., the description of "first", "second", etc. is for descriptive purposes only and is not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature.

The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

As shown in fig. 1-3, the utility model provides a high silence wind wheel suitable for electric fan heater, wind wheel 1 includes a plurality of blades 11, annular connecting portion 2 and supporting part 3, blade 11 is around setting up on annular connecting portion 2, it is concrete, both ends are connected with an annular connecting portion 2 respectively about blade 11, two annular connecting portions 2 form an annular structure with blade 11, supporting

part

3 and 2 inner circle fixed connection of annular connecting portion of below, 3 central points of supporting part put and are equipped with pivot 31, annular connecting portion 2 uses pivot 31 to drive blade 11 as the center and rotate.

Specifically, supporting part 3 includes bottom plate 4 and a plurality of backup pad 5, backup pad 5 upper end is connected with

bottom plate

4, 5 lower extremes of backup pad and the 12 inner circles of annular connecting portion are connected, 4 central point on bottom plate puts and is equipped with mounting hole 7, pivot 31 is installed in mounting hole 7, through backup pad 5 with bottom plate 4 with be connected with the 2 fixed connection of annular connecting portion of blade 11, and provide effectual rigid support to annular connecting portion 2, the preferred, install supporting shoe 71 in the mounting hole 7, supporting shoe 71 is connected with pivot 31, it is concrete, supporting shoe 71 is the rigidity material, support piece 71 takes place to deform when preventing that wind wheel 1 is connected with pivot 31, avoid wind wheel 1 to take place the shake in the course of the work, the noise production.

In this embodiment, six support plates are arranged between the bottom plate 4 and the annular connecting portion 2, that is, the six support plates are arranged around the edge of the bottom plate 4 at equal intervals, so that the gravity center of the wind wheel 1 is prevented from shifting, and the wind wheel 1 shakes due to the shifting of the gravity center in the rotating process, thereby generating noise.

In this embodiment, 5 upper ends of backup pad are buckled and are connected with bottom plate 4, and the department of buckling sets up to the arc angle, can effectively avoid sharp-pointed angle to leading to the fact the unnecessary injury to the installation when the installation, and stability between improvement bottom plate 4 that can be further and backup pad 5.

In this embodiment, the blade 11 of the wind wheel 1 is provided with the dynamic balance weight 12, so as to improve the stability of the wind wheel 1 during high-speed rotation, reduce the vibration of the wind wheel, and reduce the noise.

In this embodiment, the blades 11 of the wind wheel 1 are bent inward to form an arc-shaped structure, so that the area contacting with wind in unit length is increased, and the air intake is effectively increased.

The preferred, the distance between two adjacent blades 11 is even and between 3mm-15mm, if the distance between blade 11 is less than 3mm, then blade 11 is too intensive, 1 side of wind wheel has more area to be sheltered from, it is relatively poor to lead to the outside effect that flows of air easily, be unfavorable for the transport to the wind, if the distance between blade 11 is greater than 15mm, then the gap between blade 11 is too big, make 1 unit interval of wind wheel carry the amount of wind to reduce under the same power, efficiency reduces.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
