Description

Technical Field

[0001] The utility model relates to the technical field of fans, in particular to a full-angle fan. Background Art

[0002] Existing fans on the market, except for ceiling fans that can cover a larger area when working, other fans can only provide wind in one direction. For example, although the oscillating fan can oscillate back and forth within a 360° range, the angle of the fan head determines the direction of the wind. There is no wind at the angle where the fan head is not facing. In some office places, ceiling fans are not installed on the ceiling. When people in the room are relatively dispersed, oscillating fans are used for cooling, and office workers can only get wind intermittently. This needs to be improved. Utility Model Content

[0003] In order to solve the problems mentioned in the background technology, the purpose of the utility model is to provide an all-angle fan.

[0004] In order to achieve the above objectives, the technical solution of the utility model is:

[0006] Furthermore, the bottom surface of the first ring body transitions to the arc surface of the outer wall of the inner cover body, and the top surface of the second ring body transitions to the arc surface of the inner wall of the outer cover body.

[0007] Furthermore, the outer wall of the first cylinder body transitions to the outer wall of the inner cover body in an arc surface, and the inner wall of the second cylinder body transitions to the inner wall of the outer cover body in an arc surface.

[0008] The beneficial effects of the utility model are as follows: the inner cover body, the outer cover body, the first ring body and the second ring body together form an air guide cover, and the wind from bottom to top generated by the impeller passes between the inner cover body and the outer cover body, and is converted into horizontal wind after passing through the first ring body and the second ring body and is blown out, and the wind will be blown out at an angle of 360°, achieving a full-angle blowing effect.

[0013] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field belong to the protection scope of the utility model.

[0014] like Figure 1-Figure 3As shown, a full-angle fan includes a motor 1, an impeller 2, a support tube 3, an inner cover body 4 and an outer cover body 5, the inner cover body 4 is arranged in the outer cover body 5, the openings of the inner cover body 4 and the outer cover body 5 are both arranged upward, the distance between the outer wall of the inner cover body 4 and the inner wall of the outer cover body 5 gradually decreases from bottom to top, the top edge of the inner cover body 4 is formed with a first ring body 41, the top edge of the outer cover body 5 is formed with a second ring body 51, the first ring body 41 and the second ring body 51 correspond to each other and are arranged at intervals in the longitudinal direction, a support arm 31 is transversely arranged on the upper part of the inner wall of the support tube 3, the motor 1 is longitudinally mounted on the support arm 31, the impeller 2 is fixedly connected to the main shaft of the motor 1, the impeller 2 is located below the support arm 31, and the impeller 2 is connected to the support arm 31. The outer cover body 5 is adapted to the cylinder 3, the bottom of the inner cover body 4 is fixedly connected with the first cylinder 42, the first cylinder 42 is installed on the cross arm and the motor 1 is installed in the first cylinder 42, the bottom of the outer cover body 5 is open and fixedly connected with the second cylinder 52, the bottom of the second cylinder 52 is connected with the top of the support cylinder 3, the first cylinder 42 and the second cylinder 52 are coaxially arranged, and a plurality of ventilation holes 32 are arranged on the peripheral wall of the connecting cylinder below the impeller 2, wherein the bottom surface of the first ring body 41 transitions with the outer wall arc surface of the inner cover body 4, the top surface of the second ring body 51 transitions with the inner wall arc surface of the outer cover body 5, the outer wall of the first cylinder 42 transitions with the outer wall arc surface of the inner cover body 4, and the inner wall of the second cylinder 52 transitions with the inner wall arc surface of the outer cover body 5.

[0015] In actual use, when the motor 1 is turned on, the impeller 2 will generate wind from bottom to top.
