Description

Technical Field

[0001] This utility model relates to an air outlet device that promotes airflow, specifically a device that can guide the airflow discharged from the air outlet device in a double layer. Background Technology

[0002] Currently, the air deflectors of air outlet devices on the market can only guide the airflow of the outlet device. The devices are basically achieved through a single deflector, resulting in a relatively simple airflow experience.

[0003] A double-layered, counter-rotating air guide plate, disclosed by the Chinese Patent Office on March 17, 2023 (patent number 202223243474.8), includes an outer frame and a central seat mounted on the outside of the air outlet of an air outlet device. The central seat is mounted on a central screw at the air outlet. A large air guide ring and a small air guide ring are arranged between the outer frame and the central seat. Multiple air guide strips are arranged between the inner and outer sides of the large and small air guide rings. These air guide strips are inclined to the air outlet direction of the air outlet device, and the air guide strips on the large and small air guide rings are inclined in opposite directions. When the air outlet device discharges air, the large and small air guide rings can rotate in opposite directions simultaneously. This type of air guide plate can only blow out two opposing airflows individually, which cannot satisfy the user's need for a more varied airflow experience. Summary of the Invention

[0004] The purpose of this utility model is to address the defects and shortcomings of the prior art by providing a guide plate that enables the air outlet device to blow out a gentle breeze.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: the double-layer spiral air guiding device includes an outer air guiding ring and an inner air guiding ring. The outer air guiding ring is connected to the outer edge of the air outlet of the air outlet device, and the inner air guiding ring is fitted onto the central bolt of the air outlet of the air outlet device. Multiple arc-shaped air guiding vanes are provided inside both the outer and inner air guiding rings, and the arc-shaped air guiding vanes are arranged in a spiral. The outer and inner air guiding rings can be installed in both directions. When the air outlet device blows out from the front or back of the outer and inner air guiding rings, it can form a clockwise or counterclockwise spiral airflow.

[0006] A limiting baffle is installed on the central bolt of the air outlet of the air outlet device, and a hand-tightening end cap is provided at the outer end of the central bolt. A friction ring is provided at the center of the inner air guide ring. The hand-tightening end cap and the limiting baffle are located on the front and rear sides of the friction ring. Rotating the hand-tightening end cap can adjust the maximum static friction between the hand-tightening end cap and the friction ring. When the tangential component of the force generated by the wind blowing over the inner air guide ring is greater than the maximum static friction, the inner air guide ring will rotate.

[0007] The outer ring of the outer air guide ring is fixedly connected to the outer edge of the air outlet of the air outlet device by screws or clips.

[0008] The outer and inner air guide rings are on the same horizontal plane, and there is a gap between them.

[0009] The inner fixing ring of the outer air guide ring is offset backward, and the outer fixing ring of the inner air guide ring is located in front of the inner fixing ring of the outer air guide ring, and the projection of the outer fixing ring of the inner air guide ring overlaps with that of the inner fixing ring of the outer air guide ring.

[0010] This invention changes the spiral direction of the outer and inner air outlets by installing the outer and inner air guide rings in opposite directions. The inner air guide ring can also rotate automatically, making the inner spiral airflow gentler and allowing users to experience a variety of different airflow sensations to meet their individual needs.

[0018] like Figure 1 , Figure 2 As shown, this utility model is a double-layer spiral air guiding device, which includes an outer air guide ring 5 and an inner air guide ring 6. Multiple arc-shaped air guide vanes 5.2 and 6.2 are arranged spirally within both the outer and inner air guide rings 5 ​​and 6. Both the outer and inner air guide rings 5 ​​and 6 can be installed in either direction. When the air outlet blows air from either the front or back of the outer and inner air guide rings 5 ​​and 6, it forms a clockwise or counterclockwise spiral airflow. This spiral airflow allows the air outlet to travel a greater distance.

[0019] The outer ring 5.1 of the outer air guide ring 5 is fixedly connected to the outer edge of the air outlet 1 of the air outlet device by screws or clips. The inner air guide ring 6 is located in the middle of the outer air guide ring 5, and the outer air guide ring 5 and the inner air guide ring 6 are on the same horizontal plane, with a gap 7 between them. A central bolt 3 is provided at the center of the air outlet 1 of the air outlet device, and the rear end of the central bolt 3 is fixed to the inner wall of the air outlet 1 of the air outlet device by a cross fixing bracket 2. A limiting baffle 4 is installed on the central bolt 3, and the limiting baffle 4 is fixed to the central bolt 3 by a nut and a retaining ring. The inner air guide ring 6 is fitted onto the central bolt 3 and is located in front of the limiting baffle 4. A hand-tightening end cap 8 is provided at the outer end of the central bolt 3. A friction ring 6.1 is provided at the center of the inner air guide ring 6. The hand-tightening end cap 8 and the limiting baffle 4 are located on the front and rear sides of the friction ring 6.1. Rotating the hand-tightening end cap 8 can adjust the maximum static friction between the hand-tightening end cap 8 and the friction ring 6.1. When the tangential component of the force generated by the wind blowing over the inner air guide ring 6 is greater than the maximum static friction, the inner air guide ring 6 will rotate. The spiral wind blown out by the inner air guide ring 6 loses some kinetic energy after rotating, so the spiral wind becomes gentler. Moreover, the outer air guide ring 5 and the inner air guide ring 6 are on the same horizontal plane, and a gap 7 is left between the outer air guide ring 5 and the inner air guide ring 6. Therefore, the inner air guide ring 6 will not rub against the outer air guide ring 5 when rotating.

[0020] like Figure 2 In the middle, both the outer air guide ring 5 and the inner air guide ring 6 can blow out a clockwise spiral airflow. When the end cap 8 is loosened by hand, the inner air guide ring 6 rotates, and the clockwise spiral airflow becomes gentler. The faster the inner air guide ring 6 rotates, the gentler the airflow. Figure 3 When the inner air guide ring 6 is reversed, it blows out a counter-clockwise spiral airflow, while the outer air guide ring 5 blows out a clockwise spiral airflow. When the end cap 8 is loosened by hand, the inner air guide ring 6 rotates, and the counter-clockwise spiral airflow becomes gentler. The faster the inner air guide ring 6 rotates, the gentler the airflow. Figure 4 As shown, when the outer air guide ring 5 is reversed, it blows out a counter-clockwise spiral airflow, while the inner air guide ring 6 blows out a clockwise spiral airflow. When the end cap 8 is loosened by hand, the inner air guide ring 6 rotates, and the clockwise spiral airflow becomes gentler. The faster the inner air guide ring 6 rotates, the gentler the airflow. Therefore, users can experience a variety of different airflow sensations to meet their individual needs.

[0021] like Figure 5 , Figure 6As shown, in another embodiment of this utility model, the inner fixing ring 5.3 of the outer air guide ring 5 is offset backward, and the outer fixing ring 6.3 of the inner air guide ring 6 is located in front of the inner fixing ring 5.3 of the outer air guide ring 5, and the projection of the outer fixing ring 6.3 of the inner air guide ring 6 overlaps with that of the inner fixing ring 5.3 of the outer air guide ring 5. Thus, visually, the inner air guide ring 6 and the outer air guide ring 5 appear as one unit, while the inner air guide ring 6 can still rotate independently. Figure 7 As shown, when the inner air guide ring 6 is reversed, it blows out a counterclockwise spiral airflow, while the outer air guide ring 5 blows out a clockwise spiral airflow.

[0022] This utility model changes the spiral direction of the outer air outlet and the inner air outlet by installing the outer air guide ring 5 and the inner air guide ring 6 in opposite directions. The inner air guide ring 6 can also rotate automatically, thereby making the inner spiral wind softer and allowing users to experience a variety of different wind sensations to meet their individual needs.
