Description

TECHNICAL FIELD

[0001] The present utility model relates to the technical field of air purification equipment, and in particular discloses a variable air-direction air supply outlet.

BACKGROUND ART

[0002] Air supply outlets are widely used in the prevention and control of indoor air pollution in various public places, and are widely used in the new construction and renovation of clean projects in the pharmaceutical, health, electronics, chemical and other industries; air filtered through the air supply outlets is delivered indoors, which effectively ensures that indoor air quality reaches an ideal state. An air supply outlet mainly consists of a box body, a diffuser plate, a filter, and a regulating valve, among which the diffuser plate functions to guide the discharge of air. In the air supply outlets on the market, the diffuser plate is fixedly installed below the box body; since a flat-plate diffuser plate is used, the air discharge area is small, resulting in low air change efficiency. In addition, the air discharge direction is fixed, and air can only be blown continuously in one direction, making it difficult to satisfy consumers' requirements for air blowing.

SUMMARY OF THE UTILITY MODEL

[0003] In view of this, it is necessary, in addressing the problems of the prior art, to provide a variable air-direction air supply outlet having a unique structure, which can increase the air discharge area, automatically change the air discharge direction, and improve the air change efficiency.

[0004] To solve the problems of the prior art, the present utility model discloses a variable air-direction air supply outlet, comprising a box body and a regulating valve, the regulating valve being fixedly connected at an air inlet of the box body; the box body comprises an inner cavity; an air outlet communicating with the inner cavity is defined through the bottom of the box body; a filter is fixedly connected in the inner cavity at the air outlet; an arc-shaped diffuser shell is provided below the box body, the arc-shaped diffuser shell comprising an air collection cavity and an arc-shaped diffuser plate located at one side of the air collection cavity; an air collection port communicating with the air collection cavity is defined through the top of the arc-shaped diffuser shell, the shape of the air collection port matching the shape of the bottom of the box body; the bottom of the box body is arranged on the air collection port; a lug A and a lug B are respectively provided on two opposite sides of the arc-shaped diffuser shell; the lug A is rotatably connected to one side wall of the box body; a motor is fixedly connected to one side of the inner cavity, and an output shaft of the motor is fixedly connected to the lug B; and a plurality of air exhaust holes are equally spaced through the arc-shaped diffuser plate.

[0005] Preferably, the arc-shaped diffuser shell further comprises air baffle plates fixedly connected to two opposite sides of the arc-shaped diffuser plate, and arc-shaped receding portions are provided on both opposite sides of the bottom of the box body.

[0006] Preferably, a silicone block matching the shape of the inner cavity is bonded in the inner cavity at one side of the air outlet, a socket matching the filter is defined through a middle portion of the silicone block, and the filter is arranged on the socket.

[0007] Preferably, a plurality of electric heating wires are provided in the air collection cavity.

[0008] Preferably, the diameter of each air exhaust hole is 5 mm.

[0009] The present utility model has the following beneficial effects: the present utility model discloses a variable air-direction air supply outlet having a unique structure; air passes through the regulating valve into the inner cavity and, after being filtered by the filter, enters the air collection cavity; a plurality of air exhaust holes are equally spaced through the arc-shaped diffuser plate, increasing the air discharge area. The motor drives the arc-shaped diffuser shell to swing back and forth around the box body, and the air flow in the air collection cavity is discharged through the air exhaust holes, forming a changing air direction. The structure is simple and convenient to use; the air discharge area can be increased, the air discharge direction can be changed automatically, and the air change efficiency improved. When the motor drives the arc-shaped diffuser shell to swing back and forth, the arc-shaped receding portions are provided to avoid blocking the movement of the air baffle plates, ensuring that the arc-shaped diffuser shell swings stably. The filter is fixed at the air outlet by the silicone block, improving the filtration sealing so as to prevent unfiltered air in the inner cavity from leaking out from the air outlet. The electric heating wires generate heat after being energized, and the air flow in the air collection cavity is heated by the electric heating wires and then discharged through the air exhaust holes, forming hot air.
