The upper surface of the air guiding ring 20 may be a plane, or may be a curved surface protruding upward, etc., which is not particularly limited herein. It should be noted that, when the upper surface of the air guiding ring 20 is in direct contact with the air in the air outlet channel, and the upper surface of the air guiding ring 20 can change the flow direction of the air contacting with the air guiding ring, this also makes the upper surface of the air guiding ring 20 have an air guiding effect, and the upper surface of the air guiding ring 20 is set to be inclined downward, this makes the upper surface of the air guiding ring 20 extend in the radial direction of the air outlet 112 and shield part of the air outlet 112, and before passing through the air outlet 112, part of the air in the air outlet channel contacts with the upper surface of the air guiding ring 20, and the air contacting with the upper surface of the air guiding ring 20 is guided by the upper surface of the air guiding ring 20 to flow out of the air outlet 112 along the extending direction of the upper surface of the air guiding ring 20, compared with setting the upper surface of the air guiding ring 20 to be inclined downward, in this embodiment, the upper surface of the air guiding ring 20 is set to be inclined downward, and the air guiding ring 112 is not inclined downward, and the air guiding ring is connected to the air outlet 100, and the air guiding ring is prevented from being inclined, and the air outlet 100 is further connected to the air outlet; and the appearance of whirl can also increase the air-out noise of smallpox machine 100, will the upper surface of wind-guiding ring 20 sets up to the inclined plane and can also reduce to a certain extent the air-out noise of smallpox machine 100, and then is favorable to improving user's experience.

In order to facilitate the installation of the air guide ring 20, referring to fig. 4, the panel assembly 11 includes a panel 113 and an annular sleeving plate 114 extending upward from the panel 113, and it should be noted that the annular sleeving plate 114 is convexly disposed at a position between the air inlet 111 and the air outlet 112 of the panel assembly 11.

It should be noted that the transmission mechanism 32 is various, and in one embodiment of the present invention, referring to fig. 2 and 3, the transmission mechanism 32 includes a rotating wheel 321. Specifically, the surface of the panel assembly 11 facing the air guide ring 20 is provided with a plurality of first guiding elements 115 extending radially along the air outlet 112 and arranged along the circumferential direction of the air outlet 112; the rotating wheel 321 is sleeved on the output shaft of the motor 31, and the rotating wheel 321 is also in transmission connection with the first guiding element 115.

When the motor 31 drives the rotating wheel 321 to rotate, the rotating wheel 321 moves along the first guiding element 115, so that the air guiding sub-plate 22 moves along the radial direction of the air outlet 112 along with the rotating wheel 321, and when the two air guiding plates 21 are moved along the radial direction of the air outlet 112, the two ends of the air guiding plates 21 have the speed along the radial direction of the air outlet 112, and the speeds at the two ends of the air guiding plates 21 are combined to be along the radial direction of the air outlet 112, so that the air guiding plates 21 can move along the radial direction of the air outlet 112, and the air guiding ring 20 can stretch along the radial direction of the air outlet 112.

Since the runner 321 contacts with the groove wall of the first chute in the length direction, when the motor 31 drives the runner 321 to rotate, the runner 321 rolls along the groove wall of the first chute in the length direction due to the friction force between the runner 321 and the groove wall of the first chute, so that the first chute has guiding function and driving function; and, the wind-guiding auxiliary plate 22 moves along the first chute under the driving of the rotating wheel 321, so that the wind-guiding auxiliary plate 22 can move along the radial direction of the air outlet 112, and the wind-guiding ring 20 can extend and retract along the radial direction of the air outlet 112.

It should be noted that, as the working time of the runner 321 increases, the wear degree of the runner 321 increases, which may cause slippage between the runner 321 and the wall of the first chute, so that the air guiding sub-plate 22 cannot move along the radial direction of the air outlet 112. In view of this, in an embodiment of the present invention, a rack is provided on a groove wall of the first chute in a length direction thereof, and the rack is provided to extend in the length direction of the first chute; the rotating wheel 321 is a gear meshed with the rack.

When the runner 321 rolls along the first sliding groove, the balls 322 roll relative to the first sliding groove, so that sliding friction between the runner 321 and the bottom of the first sliding groove is changed into rolling friction, the runner 321 can roll along the first sliding groove smoothly, and the air guide auxiliary plate 22 can slide along the radial direction of the air outlet 112 relative to the panel 113 smoothly.

Obviously, the transmission mechanism 32 may also be a chain and a sprocket, that is, the chain is disposed along the radial extension of the air outlet 112, the sprocket is connected to the output shaft of the motor 31, and the sprocket rotates relative to the chain under the driving of the motor 31, so that the air guiding sub-plate 22 can be driven to move along the radial direction of the air outlet 112.

In addition, the transmission mechanism 32 may further comprise a rotating wheel 321 and a flexible wire, that is, the flexible wire is mounted on the panel assembly 11 and extends along the radial direction of the air outlet 112, and the flexible wire is wound around the rotating wheel, so that the rotating wheel 321 is driven by the motor 31 to rotate back and forth along the flexible line, so as to drive the air guide auxiliary plate 22 to move along the radial direction of the air outlet 112.

In order to facilitate the sliding of the air guide plates 21 relative to the two air guide sub-plates 22, in an embodiment of the present invention, referring to fig. 3 and 5, two ends of the air guide plates 21 are respectively provided with second guide members 211 extending along the extending direction of the air guide plates 21; the transmission mechanism 32 further comprises a driving wheel 323 sleeved on the output shaft of the motor 31, a driven wheel 324 installed on the wind guiding sub-board 22 and in transmission connection with the second guide member 211, and a transmission belt 325 in transmission connection with the driving wheel 323 and the driven wheel 324.

It should be noted that the second guide 211 not only has a guiding function, but also has a transmission relationship with the driven wheel 324. When the motor 31 drives the driving wheel 323 to rotate, the distance between the driving wheel 323 and the driven wheel 324 is fixed, so that the driven wheel 324 is driven by the driving belt 325 to perform rotary motion; and the driven wheel 324 is in driving connection with the second guide 211, that is, when the driven wheel 324 rotates, the driven wheel 324 rolls relative to the second guide 211, and since the air guiding auxiliary plate 22 can only move along the radial direction of the air outlet 112 and the air guiding plate 21 is in sliding connection with the air guiding auxiliary plate 22, the air guiding plate 21 can slide relative to the air guiding auxiliary plate 22, so that the air guiding plate 21 can slide relative to the two air guiding auxiliary plates 22 while ensuring the air guiding auxiliary plate 22 to move along the radial direction of the air outlet 112, and the air guiding ring 20 can extend and retract along the radial direction of the air outlet 112.

The second guide 211 may be another structural member such as a rack, an elongated groove, etc., and the second guide 211 is not particularly limited herein. In an embodiment of the present invention, two ends of the air deflector 21 are provided with second sliding grooves along the extending direction of the air deflector 21, and each second sliding groove forms the second guiding element 211; the driven wheel 324 is installed in the second chute and abuts against a slot wall of the second chute along the length direction thereof.

When the motor 31 drives the driven wheel 324 to rotate, the driven wheel 324 rolls along the groove wall of the second chute along the length direction of the second chute, and generates an interaction friction force with the groove wall of the second chute, but the air guiding auxiliary plate 22 can only move along the radial direction of the air outlet 112, that is, the position of the driven wheel 324 along the extending direction of the air guiding plate 21 cannot be changed, so that the air guiding plate 21 slides relative to the air guiding auxiliary plate 22, and the length of the assembly formed by the air guiding plate 21 and the two air guiding auxiliary plates 22 is increased, and therefore, when the air guiding ring 20 stretches along the radial direction of the air outlet 112, the air guiding ring 20 can still guide air at all positions of the air outlet 112.

Further, the second guide 211 is extended along a tangential direction of the end of the wind deflector 21. The arrangement is such that the second guide 211 is arranged in a straight line, and the guiding effect of the second guide 211 arranged in a straight line is better than that of the second guide 211 arranged in a curve, that is, the resistance of the driven wheel 324 when moving along the second guide 211 arranged in a straight line is smaller than that of the driven wheel 324 when moving along the second guide 211 arranged in a curve, so that the friction between the driven wheel 324 and the second guide 211 is reduced, and the driven wheel 324 can slide along the second guide 211 more smoothly, and meanwhile, the noise generated when the driven wheel 324 moves along the second guide 211 can be reduced.

It should be noted that, as the working time of the driven wheel 324 increases, the abrasion degree of the driven wheel 324 increases, which causes a slip between the driven wheel 324 and the wall of the second chute, so that the air deflector 21 cannot slide relative to the air deflector 22. In view of this, in an embodiment of the present invention, a rack is provided on a groove wall of the second chute in a length direction thereof, and the rack is provided to extend in the length direction of the second chute; the driven wheel 324 is a gear that meshes with the rack.

The gear and the rack have stable transmission, so that when the transmission belt 325 drives the gear to rotate, the gear can smoothly roll along the rack, and the air deflector 21 can slide relative to the air deflector 22; and the gear and the rack are also wear resistant, thus ensuring the operational life of the transmission 32.

Obviously, to enable the two air guiding sub-plates 22 to slide relative to the air guiding plate 21, other manners may be adopted, and in another embodiment of the present invention, the air guiding sub-plates 22 are connected to the air guiding plate 21 in a sleeved manner. It should be noted that, the diameter of the circle corresponding to the air guiding sub-plate 22 is equal to the diameter of the circle corresponding to the air guiding plate 21, so that after the air guiding sub-plate 22 is sleeved with the air guiding plate 21, the air guiding sub-plate 22 can slide along the extending direction of the air guiding plate 21, that is, the circumference of the circle corresponding to the air guiding plate 21. And the air deflector 21 and the air deflector 22 are connected in a sleeved mode, so that when the air deflector 22 slides relative to the air deflector 21, larger jump is not generated, and further stable sliding of the air deflector 22 relative to the air deflector 21 is ensured.

It may be understood that the sleeving connection between the air guiding auxiliary plate 22 and the air guiding plate 21 may be that the air guiding auxiliary plate 22 is sleeved at the end of the air guiding plate 21, or that the end of the air guiding plate 21 is sleeved in the air guiding plate 21, or that the air guiding plate 21 and the air guiding auxiliary plate 22 are mutually sleeved. In the embodiment of the present invention, the air deflector 21 and the air deflector 22 are sleeved with each other, specifically, the air deflector 21 includes an upper air deflector 212 and a lower cover plate 213 covering the lower surface of the upper air deflector 212, and the end of the lower cover plate 213 is in clearance fit with the end of the upper air deflector 212 to form a sliding channel; the air guiding sub-plate 22 comprises a sliding plate 221 slidably mounted in the sliding channel, and an upper air guiding sub-plate 222 connected with one side of the sliding plate 221 and covering the upper cover plate. The arrangement is such that the connection between the wind deflector 21 and the wind deflector 22 is stable.

The foregoing description is only of the preferred embodiments of the present invention and is not intended to limit the scope of the invention, and all equivalent structural changes made by the description of the present invention and the accompanying drawings or direct/indirect application in other related technical fields are included in the scope of the invention.
