DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Reference Figures 1 to 5As shown, in order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a fan with adjustable air outlet, comprising a frame 1 and a fan assembly 11, the fan assembly 11 is installed in the frame 1, the frame 1 is provided with an air inlet 12 and an air outlet 13, the frame 1 comprises a main shell 2, an air outlet plate 3 and an air inlet plate 4, the air outlet plate 3 and the air inlet plate 4 are both arranged in an annular structure, the air inlet 12 is arranged on the air inlet plate 4, and the air outlet 13 is arranged on the air outlet plate 3; The air outlet plate 3 and the air inlet plate 4 are both rotatably connected to the main housing 2 and are respectively located on both sides of the fan assembly 11. A first limiting plate 31 and a second limiting plate 41 are provided between the air outlet plate 3 and the air inlet plate 4. The first limiting plate 31 is connected to the air outlet plate 3, and the second limiting plate 41 is connected to the air inlet plate 4. The first limiting plate 31 and the main housing 2 are combined to form a limited space, and the second limiting plate 41 is slidably connected in the limited space. A first limiting assembly 5 is provided between the air outlet plate 3 and the main housing 2 , a second limiting assembly 6 is provided between the air inlet plate 4 and the main housing 2 , and a one-way controlled linkage component 7 is provided between the second limiting assembly 6 and the first limiting assembly 5 .

[0021] The design of the present invention adjusts the positional relationship between the air inlet 12 and the air outlet 13 according to the installation environment or installation requirements, and during the adjustment process, the second limiting plate 41 is limited by the area of ​​the first limiting plate 31, so that the air outlet 13 always maintains a certain angle with the air inlet 12. After the position of the air inlet 12 is determined, the air outlet plate 3 is rotated. Since the rotation angle of the air outlet plate 3 is limited, a series of problems that may be caused by the angle between the air inlet 12 and the air outlet 13 being too small are effectively avoided, that is, the variability of the installation of the fan air inlet 12 and the air outlet 13 is ensured, and the stability of the fan installation is ensured.

[0022] During the installation process, when adjusting the position of the air inlet 12, the linkage component 7 can be used to ensure that the air outlet plate 3 does not hinder the rotation of the air inlet plate 4. During the adjustment of the position of the air outlet 13, since the second limiting plate 41 is fixed, the rotation angle of the air outlet plate 3 is limited, and the position of the air inlet 12 will not change.

[0023] like Figure 1 As shown, the air outlet plate 3 is assembled on one side of the main housing 2 ; the air inlet plate 4 is embedded in the middle of the main housing 2 .

[0024] The present invention is further configured as follows: the first limiting assembly 5 includes a plurality of groups of first limiting bolts 51 , and the first limiting bolts 51 connect the main housing 2 with the air outlet plate 3 along the axial direction of the main housing 2 and the air outlet plate 3 .

[0025] like Figure 1As shown, the design of this structure can firmly limit the main housing 2 and the air outlet plate 3 by tightening the first limiting bolt 51, thereby preventing the air outlet plate 3 from rotating.

[0026] The present invention is further configured as follows: the first limiting assembly 5 further includes a positioning rod 52 and a positioning plate 53, the positioning rod 52 is fixedly connected to the air outlet plate 3, and the main housing 2 is provided with an annular slot 21 for the positioning rod 52 to be inserted and limited, and the positioning rod 52 is used for axial positioning; The positioning plate 53 is slidably connected to the air outlet plate 3 . A positioning groove 22 is provided on the main housing 2 . The positioning plate 53 is used for circumferential positioning.

[0027] One end of the positioning rod 52 close to the main housing 2 is arranged in an arc-shaped structure, and the other end is hingedly arranged on the air outlet plate 3.

[0028] like Figure 4 and Figure 3 As shown, the positioning rod 52 is designed to be inserted into the annular slot 21, and due to the design of the rod head of the positioning rod 52, it can be embedded when inserted to form a fixation. The design of the positioning rod 52 and the annular slot 21 is a common hook-shaped fit, which is not elaborated here, to ensure that the air outlet plate 3 and the main shell 2 will not be separated in the absence of external force. When an external force breaks or the positioning rod 52 is pushed through the groove on one side, the positioning rod 52 can be separated from the annular slot 21.

[0029] The present invention is further configured as follows: the positioning plate 53 is arranged in an annular structure, and the positioning plate 53 is provided with a plurality of sliding grooves 531 along its circumference, and the sliding grooves 531 are each provided with a return spring 532 and a positioning iron bead 533 which is slidingly connected thereto, the positioning groove 22 includes a plurality of bead grooves for one-to-one embedding of the positioning iron bead 533, and a magnetic attraction layer is arranged in the positioning groove 22.

[0030] The design of this structure enables the air outlet plate 3 to be fitted with the main housing 2 through the positioning rod 52 , so that the positioning iron bead 533 can be fitted with the positioning groove 22 , thereby properly fixing the position of the air outlet plate 3 and preventing it from rotating.

[0031] like Figure 3 and Figure 4 As shown, there are multiple groups of positioning iron beads 533 and bead grooves, and the angle difference between two adjacent groups is small, so that various angle designs of the air outlet 13 can be satisfied.

[0032] The present invention is further configured as follows: an extension plate is provided at one end of the air inlet plate 4 facing the main shell 2, the extension plate is located on the inner side of the main shell 2, the second limiting assembly 6 includes multiple groups of second limiting bolts 61, and the first limiting bolts 51 are connected to the main shell 2 and the extension plate along the radial direction of the main shell 2.

[0033] The design of this structure can fix the air inlet plate 4 in a limited position.

[0034] The present invention is further configured as follows: the positioning plate 53 includes an abutment portion 54 located on the inner side, the linkage component 7 includes a linkage switch 71 and a linkage rod 72, the linkage switch 71 is threadedly lifted and connected to the air inlet plate 4, the lower end of the linkage switch 71 is abutted against the linkage rod 72, and the linkage rod 72 is slidably connected to the second limit plate 41 through a linkage spring; The advantage of this threaded connection is that it can avoid the positioning iron bead 533 and the bead groove from being re-fitted.

[0035] When the linkage switch 71 moves downward, it can push the linkage rod 72 to slide out from the second limit plate 41 toward the air outlet plate 3 , and the abutting portion 54 is provided with a linkage ring groove 541 for the linkage rod 72 to be inserted into.

[0036] Since the depth dimension of the linkage ring groove 541 is smaller than the extension dimension of the linkage rod 72, when the linkage rod 72 is inserted into the linkage ring groove 541, it can push the positioning plate 53 to move into the annular groove, thereby separating the bead groove and the positioning iron bead 533 to ensure the convenience of rotation.

[0037] The present invention is further configured as follows: an annular groove is provided on the air outlet plate 3, an energy storage spring is provided in the annular groove, one end of the positioning plate 53 is connected to the energy storage spring and is slidably connected in the annular groove.

[0038] The design of this structure is that when the linkage rod 72 is extended, the positioning plate 53 can slide inward along the annular groove. When the linkage rod 72 is retracted, the positioning plate 53 is extended under the action of the energy storage spring, so that the bead groove and the positioning iron bead 533 fit together again.

[0039] The present invention is further configured as follows: an air outlet block is detachably mounted on the air outlet plate 3 , and an air inlet block is detachably mounted on the air inlet plate 4 .

[0040] The design of this structure can form different air inlet and outlet forms by replacing the air outlet blocks and air inlet blocks of different air ducts to meet the needs of various environments.

[0041] The above are only preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
