Description

Technical Field

[0001] This utility model relates to an air guiding device for guiding the air discharged from the air outlet device, specifically an air guiding plate with switchable single and double layer air guiding modes. 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 air guide plate does not provide a switchable single or double-layer air guide mode for customers to choose from. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings and deficiencies of the prior art by providing a switchable single or double-layer air guide plate for use in air outlet devices.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: the air guide plate with switchable single and double layer air guiding modes includes an outer frame of the air guide plate, a first layer air guide plate is provided on the front side of the outer frame, a mounting plate is provided at the center of the first layer air guide plate, a central shaft can be installed on the mounting plate, a connecting plate is provided at the rear end of the central shaft, the connecting plate can be fixed with the mounting plate, a second layer air guide plate is movably fitted on the central shaft, and a step is provided on the central shaft to limit the inner side of the second layer air guide plate; the front end of the central shaft is a threaded head, and an end cap is screwed onto the threaded head, the end cap can limit the outer side of the second layer air guide plate.

[0006] When the end cap is tightened, the second air guide plate cannot rotate; when the end cap is loosened, the second air guide plate can rotate as the airflow passes through.

[0007] The central shaft is provided with a deformable protruding ring, which also limits the outer side of the second layer air guide plate. When the second layer air guide plate is inserted into or pulled out of the central shaft, force needs to be applied to deform the protruding ring first.

[0008] The connecting plate is connected to the mounting plate by screws.

[0009] The connecting plate is connected to the installation plate via Velcro.

[0010] The second-layer air guide plate can be installed on the front or the back, and the rotation direction of the second-layer air guide plate after installation is opposite.

[0011] The first layer of air guide plate has a groove in the center, and the second layer of air guide plate can be embedded in the groove.

[0012] The second-layer air guide plate of this utility model can be quickly disassembled and assembled, so as to select the use of single-layer air guide mode or double-layer air guide mode. The second-layer air guide plate can rotate, so that users can experience a variety of different airflow sensations to meet individual needs. Attached Figure Description

[0020] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, this utility model is an air guide plate with switchable single and double layer air guiding modes. It includes an outer frame 10 of the air guide plate, and a first layer air guide plate 20 is provided on the front side of the outer frame 10. A mounting plate 21 is provided at the center of the first layer air guide plate 20. A central shaft 40 can be mounted on the mounting plate 21. A connecting plate 41 is provided at the rear end of the central shaft 40, and the connecting plate 41 can be fixed to the mounting plate 21. The connecting plate 41 can be connected to the mounting plate 21 by screws or by Velcro.

[0021] A second-layer air guide plate 30 is mounted on the central shaft 40. A through hole 31 is provided in the center of the second-layer air guide plate 30, allowing it to be movably fitted onto the central shaft 40. A step 42 is provided on the central shaft 40, the diameter of which is larger than the through hole 31, thus limiting the inner axial movement of the second-layer air guide plate 30. A deformable protruding ring 43 is provided on the central shaft 40, which also limits the outer movement of the second-layer air guide plate 30. When the second-layer air guide plate 30 is inserted into or removed from the central shaft 40, force must be applied to deform the protruding ring 43 first. The front end of the central shaft 40 is a threaded head 44, on which an end cap 50 is screwed. The end cap 50 limits the outer movement of the second-layer air guide plate 30. When the end cap 50 is tightened, the second-layer air guide plate cannot rotate; when the end cap 50 is loosened, the second-layer air guide plate can rotate with the airflow. The end cap 50 can be turned by hand. The second-layer air guide plate can be installed on the front or the back. After installation, the second-layer air guide plate rotates in the opposite direction, thus providing a variety of different airflow experiences.

[0022] like Figure 5 As shown, an expansion plate 32 can be fitted onto the outer side of the second-layer air guide plate. After the expansion plate 32 is fitted onto the outer edge of the second-layer air guide plate and fixed, it can increase the area of ​​the second-layer air guide plate and realize the rapid adjustment of the air guiding area of ​​the second-layer air guide plate.

[0023] like Figure 6 , Figure 7 As shown, the first-layer air guide plate 20 has a groove 22 at its center, and the bottom of the groove 22 is a disc-shaped mounting plate 21. Multiple air outlet slots 23 are formed on the mounting plate 21, allowing the first-layer air guide plate 20 to be used independently. The second-layer air guide plate 30 can be embedded in the groove 22 without protruding, and its structure is similar to that of a single-layer air guide plate.

[0024] The second-layer air guide plate 30 of this utility model can be quickly disassembled and assembled, thereby selecting a single-layer air guide mode or a double-layer air guide mode. The second-layer air guide plate 30 can rotate, allowing users to experience a variety of different airflow sensations to meet individual needs.
