The wind tunnel outer cover can rotate around the wind tunnel bracket, so that the air supply angle of the wind tunnel outer cover is more flexible, and the requirement of simultaneously supplying air in different directions is met.
Description
Technical Field
The utility model relates to a domestic appliance, especially a convertible bladeless fan.
Background
The existing bladeless fans all adopt a single wind tunnel structure. The air outlet of the bladeless fan is an annular gap-shaped air groove, the air tunnel is in a horn shape or a straight cylinder shape, high-pressure air is diffused along the inner wall of the air tunnel after leaving the air outlet and is driven by high-speed airflow of the air outlet to be gradually accelerated, and an air supply surface with larger wind power is formed. Generally, a rotating seat and a structure for adjusting a pitch angle of the bladeless fan are designed in a base at the bottom of the bladeless fan. The bladeless fan of the single wind tunnel can only meet the air supply requirements of a user of one person or one fan, is not suitable for multi-path air supply, and meets the air supply requirements of users at different angles.
Generally, the air outlet of the bladeless fan cannot independently adjust the air supply angle, so that the user feels inconvenient.
Disclosure of Invention
The utility model aims to solve the technical problem that, solve the problem that single wind-tunnel property fan can not multi-angle multi-direction air supply, provide the bladeless fan design that a plurality of users lasted the air supply.
The utility model provides a technical scheme that above-mentioned problem adopted does: the utility model provides a convertible bladeless fan, is formed by wind-tunnel and host computer assembly, is provided with air inlet, high-speed motor, blade and high-speed wind channel in the host computer, and the air intake of high-speed wind channel bottom links to each other its characterized in that: the wind tunnel is provided with a rotary air outlet which is arranged on an air outlet outer cover, the air outlet outer cover is connected with the wind tunnel bracket through a rotating shaft, and the wind tunnel bracket is allowed to rotate around the center of the circle.
The rotary air outlet is arranged at the end part or the inner side wall of the air outlet outer cover.
And rotary air outlet outer covers are arranged on the two vertical air outlet outer covers of the wind tunnel.
And the air outlet outer cover on the top edge of the wind tunnel is provided with a rotary air outlet outer cover.
Compared with the prior art, convertible bladeless fan, can be simultaneously to two orientations three orientation air-outs even, the pivot on the wind tunnel in the combination, the wind-tunnel can realize multi-direction multi-angle air supply, convenient to use.

Detailed Description
Convertible bladeless fan is a wind-tunnel improvement to current bladeless fan, and the bladeless fan is formed by wind-tunnel and host computer assembly, is provided with air inlet, high-speed motor, blade and high-speed wind channel in the host computer, and the high-speed wind channel links to each other with the air intake of wind-tunnel bottom, and the host computer part is the same with current bladeless fan structure, drives the blade through high-speed motor and rotates, forms high-pressure draught to in with the leading-in wind-tunnel of high-pressure draught through the high-speed wind channel, realize the air-out through the air outlet of wind-tunnel.
Different from the prior art, the utility model discloses a wind-tunnel structure be from rotating-structure, and the wind-tunnel is similar rectangle, and the center of wind-tunnel is provided with the wind-tunnel support, and the main support of wind-tunnel respectively is provided with one or a pair of rotation axis in apex angle department, and the air-out dustcoat of wind-tunnel links to each other with this rotation axis through grafting or riveted structure. The outer wall of the wind tunnel can thus rotate around the main support of the wind tunnel.
Embodiments of the present invention are further described below with reference to the accompanying drawings. As shown in fig. 1, the two vertical air outlet housings of the wind tunnel are provided with air outlets on the forward sides, the air outlets are rotary air outlets, and the rotary air outlets allow the wind tunnel support to rotate around the center of the circle, so that the two side walls of the wind tunnel are equivalent to the two vertically distributed rotatable vertical air outlets. Air can be supplied in different directions according to actual air supply requirements.
Similarly, the air outlet outer cover on the top edge or the bottom edge of the wind tunnel can be independently provided with a rotary air outlet according to requirements, so that the air supply requirements of different pitching heights are met.
When two or more different air supply directions are needed, the air outlet outer covers at the top and the bottom can also rotate. The fan meets the air supply requirements of a single fan on multiple users at different angles.
Furthermore, a second wind tunnel is arranged in the wind tunnel, the second wind tunnel is connected with the original wind tunnel through a middle shaft, and a rotating shaft is arranged at the middle shaft.
After the second wind tunnel is arranged, when the two air outlet outer covers of the outer wind tunnel rotate to other directions, a part of air outlets can still be kept to output air to the front of the wind tunnel.
Further, in order to more effectively utilize the air suction efficiency of the wind tunnel, as shown in the third embodiment, a wind tunnel structure with a built-in air outlet is adopted, an air outlet on an air outlet outer cover of the wind tunnel structure is arranged on the inner wall of the wind tunnel, when the wind tunnel is in a default state, high-speed airflow is ejected from the rear side of the inner wall of the wind tunnel to effectively drive the air inside the wind tunnel to flow, and then a local low-pressure area is generated, so that the air on the rear side of the wind tunnel is supplemented into the wind tunnel, and the air suction efficiency of the wind tunnel. The air outlet outer cover of each side wall is further subdivided into an upper layer and a lower layer, and the four independent air outlets are totally connected with the wind tunnel bracket through rotating shafts, so that air supply at different angles is realized respectively.
