Continuing to refer to FIG. 7 , the swing member 220 is composed of a plurality of arc-shaped portions 230 , and two adjacent arc-shaped portions 230 are spaced apart. There are multiple motors 210 , and each motor 210 is connected to a corresponding arc portion 230 to drive the arc portion 230 to rotate. In this way, each motor 210 can independently drive the corresponding arc portion 230 to rotate, so as to drive the partial area of the flexible air guide ring 100 to rotate and expand, thereby changing the air outlet range and air outlet volume of the corresponding air outlet area. . It can be understood that the flexible air guide ring 100 can be an integral structure or can be a separate structure. This will be described in detail later.

There are many ways for the motor 210 to drive the corresponding arc-shaped portion 230 to rotate. Here are the following two driving ways:

Please refer to Figure 5, Figure 6 and Figure 7. Method 1: The motor 210 is provided with a gear 211, and the inner wall of the arc-shaped portion 230 is provided with a rack 212 meshing with the gear 211. The rack 212 is arranged along the The swing member 220 extends circumferentially. The motor 210 can be disposed on the mounting frame 60 . In this way, the motor 210 drives the gear 211 to rotate, thereby driving the rack 212 to rotate, thereby driving the flexible air guide ring 100 to rotate in the circumferential direction to expand or contract.

Method 2: The motor 210 is provided with a rocker arm (not shown), a chute is provided at one end of the rocker arm away from the motor 210, and a slider matching the chute is protruding from the surface of the arcuate portion. In this way, the motor 210 drives the rocker arm to swing, thereby driving the flexible air guide ring 100 to rotate in the circumferential direction to expand or contract.

The flexible air guide ring 100 can be integrally formed or provided separately. In order to facilitate the control of the expansion and contraction of the flexible air guide ring 100, the flexible air guide ring 100 is arranged in separate pieces.

Preferably, the flexible air guide ring 100 includes a plurality of arc-shaped air guide sections 110 that are spliced end to end along the same circumference. Specifically, the ceiling machine is provided with a driving device 200 corresponding to each arc-shaped air guide section 110, and the multiple drive devices 200 synchronously drive the plurality of arc-shaped air guide sections 110 to rotate in the circumferential direction to expand and contract, thereby ensuring that the outlet is The air outlet surfaces of the air outlets can all maintain a concentric ring to achieve a uniform air outlet effect; or each driving device 200 can independently drive an arc-shaped air guide section 110 to rotate and expand along the circumferential direction of the air outlet, thereby achieving independent control of the air outlet. The effect of the air outlet area.

The number of arc-shaped air guide sections 110 is 2 to 5, such as 3 or 4. Specifically, the design can be adapted according to the size of the air outlet. In order to make the air outflow from the air outlet even, the central angles corresponding to any two arc-shaped air guide sections 110 are of the same size. Such arrangement allows the plurality of driving devices 200 to synchronously drive each arc-shaped air guide section 110 to rotate and expand or contract, and the expansion and contraction deformation amounts of each arc-shaped air guide section 110 are approximately equal, thereby ensuring that each air outlet surface of the air outlet is always maintained. It is in the shape of concentric rings to achieve uniform air distribution.

In this embodiment, the number of the arc-shaped air guide sections 110 is four. Furthermore, a first partition plate 120 is provided between two adjacent arc-shaped air guide sections 110 (as shown in FIGS. 11 and 12 ). In this way, the first partition plate 120 divides the air outlet into four air outlet areas, and the motor 210 can individually drive an arc-shaped air guide section 110 to swing, thereby changing the air outlet range of the corresponding air outlet area, and will not cause relative interference. The arc-shaped air guide section 110 adjacent to the air outlet area causes interference. For example, if the arc-shaped air guide section 110 of one of the air outlet areas is driven to swing, the arc-shaped air guide section 110 is expanded and contracted, thereby increasing the air outlet range and air outlet volume of the air outlet area; at the same time, another air outlet area can be driven to expand and contract. The arc-shaped air guide section 110 of the air outlet area swings, and the arc-shaped air guide section 110 stretches, thereby reducing the air outlet range and air outlet volume of the air outlet area.

Furthermore, a second partition plate may be provided in the middle of the arc-shaped air guide section 110 . Wherein, the second partition plate and the arc-shaped air guide section 110 are integrally formed. The second dividing plate divides each arc-shaped air guide section 110 into two parts. In this way, when the motor 210 drives one part of the arc-shaped air guide section 110 to swing, it will not interfere with the other part of the arc-shaped air guide section 110. . That is to say, when the two air guide sections of the arc-shaped air guide section 110 that are separated by the second partition plate are driven asynchronously, the two sections of the air guide section will produce a gradually changing motion form, so that the two sections will The differences in the air guide section transition smoothly.

In the above two arrangement modes, the elastic return member can assist the flexible air guide ring 100 to expand or contract, thereby enhancing the elasticity of the flexible air guide ring 100 and extending the service life of the flexible air guide ring 100 .

Referring to Figure 13, in another embodiment, the flexible air guide ring 100 includes an annular body 130 and a plurality of air guide strips 140, and the plurality of air guide strips 140 are distributed along the circumference of the annular body 130. , the inner end of the air guide strips 140 is connected to the annular body 130, and the outer end extends along the radial direction of the air outlet. The upper ends of the plurality of air guide strips 140 are connected to annular flexible windshields 150. . Among them, the air guide strips 140 are made of elastic material.

In this arrangement, the motor 210 drives the air guide strip 140 to rotate, and the air guide strip 140 bends and elastically deforms, thereby changing the coverage area of the flexible air guide ring 100 at the air outlet position, that is, changing the The opening of the air outlet.

Referring to FIG. 14 , in yet another embodiment, the air guide strips 140 are arranged in a pleated shape. In this arrangement, the motor 210 drives the air guide strips 140 to rotate, and the air guide strips 140 expand or contract, thereby changing the coverage area of the flexible air guide ring 100 at the air outlet position, that is, changing the The opening of the air outlet.

Based on any of the above embodiments, in order to increase the air outlet range of the air outlet, the outer edge of the surface of the flexible air guide ring 100 is chamfered, so that the outer edge of the surface of the flexible air guide ring 100 forms a flow guide. Bevel.
