Description

Technical Field

[0001] This utility model relates to the field of turbine fans, and more particularly to a turbine fan with variable wind direction. Background Technology

[0002] A turbine fan is a common type of fluid machinery, mainly used to generate airflow or transport fluids. Its working principle is based on the combination of a turbine and a fan. It usually consists of a rotor with multiple blades that interact with the fluid (such as air) as they rotate, thereby achieving energy transfer.

[0003] By installing a wind direction adjustment structure at the outlet of the turbine blower, the airflow direction of the turbine blower can be adjusted. For example, the prior art, Chinese Patent Publication No. "CN216518859U", describes a turbine blower with a changeable wind direction, including a blower body, a fixed plate connected to one side of the blower body, an air outlet at the center of the fixed plate, a damper inside the air outlet, an adjustment disc at the upper end of the fixed plate, and a connecting shaft connected to the upper end of the damper. This utility model, by incorporating a damper, connecting shaft, movable rod, connecting block, threaded rod, sliding groove, slot, adjustment disc, first bevel gear, second bevel gear, and threaded rod, improves the turbine blower. During use, the rotation of the damper can adjust and change the direction of the airflow from the outlet, and can also block the air outlet. The structure is reasonable, improving the applicability and blowing effect of the turbine blower. At the same time, the structure is simple, tightly connected, and has good stability, facilitating user adjustment and operation, and improving the overall performance of the turbine blower.

[0004] In actual operation, a pair of screws and several bevel gears drive a pair of dampers to rotate. However, the pair of dampers can only guide the airflow to the left and right sides, and cannot guide the airflow to the top, bottom or other directions, which makes them less practical. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where a pair of dampers cannot guide airflow in vertical or other directions, and to propose a variable-direction turbine fan.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a variable wind direction turbine fan, including a turbine fan body and a support part. The turbine fan body has an air outlet duct. The support part is rotatably connected to the opening of the air outlet duct. The support part and the air outlet duct are fixed together by at least one fastening structure.

[0008] The support section has several air guide plates inside and a positioning component on the side of the support section. The air guide plates are synchronously rotated and fixed by the positioning component.

[0009] Furthermore, the fastening structure includes a screw, one end of which is fixedly connected to a butterfly-shaped part, and the other end of which is threadedly connected to the outer wall of the air outlet duct and abuts against the support part.

[0010] Furthermore, the positioning component includes a synchronizing element, and a plurality of the air guide plates are linearly and equidistantly arranged. Both sides of the air guide plates are rotatably connected to the opening side of the support part via a rotating shaft. The synchronizing element is disposed at the bottom of the air guide plate, and the synchronizing element and the plurality of air guide plates are arranged in a cross pattern.

[0011] Furthermore, the air guide plate is fixedly connected to a rotating shaft within the bottom groove, and the synchronizing element is movably connected within the groove and rotatably connected to the rotating shaft.

[0012] Furthermore, the positioning component also includes an elastic element, and the protruding part of the support on the opening side is provided with a cavity. Several positioning protrusions are distributed circumferentially on the inner wall of the cavity. The elastic element is rotatably connected in the cavity and fixedly connected to the rotating shaft of one of the air guide plates.

[0013] Furthermore, several deformation grooves are formed through both sides of the elastic member, and protrusions corresponding to the deformation grooves are distributed around the outer circumference of the elastic member. The protrusions slide against the positioning protrusions through the deformation grooves, and the protrusions also stop between two adjacent positioning protrusions.

[0014] The present invention proposes a variable airflow turbine fan, the advantages of which are as follows: The present invention provides a support part at the air outlet duct opening of the turbine fan. The support part is rotatably connected to the air outlet duct and fixed by a locking structure. This allows for the overall disassembly and replacement of the support part and its internal guide plates. Furthermore, the rotation allows the multiple guide plates to guide the airflow in multiple directions. In addition, the multiple guide plates rotate synchronously through a synchronizing element to ensure consistent airflow direction. The airflow angle of the guide plates can also be adjusted in multiple levels by the sliding contact between the protrusion and the positioning protrusion. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-5 A variable wind direction turbine includes a turbine body 1 and a support part 2. The turbine body 1 has an air outlet duct 3. The support part 2 is rotatably connected to the opening of the air outlet duct 3. The support part 2 and the air outlet duct 3 are fixed together by at least one fastening structure 4.

[0023] The support part 2 has several air guide plates 5 inside, and a positioning component 6 is provided on the side of the support part 2. The air guide plates 5 are synchronously rotated and fixed by the positioning component 6.

[0024] Furthermore, the fastening structure 4 includes a screw 41, one end of which is fixedly connected to a butterfly part 42, and the other end of which is threadedly connected to the outer wall of the air outlet duct 3 and abuts against the support part 2.

[0025] In this embodiment, the outer wall of the support part 2 is circumferentially distributed with several positioning grooves. By rotating the screw 41 through the butterfly part 42, one end of the screw 41 stops in the positioning groove, which further improves the fastness of fixing the support part 2.

[0026] Specifically, because the several air guide plates 5 are restricted by the synchronizing member 61, they can only rotate half a circle along the length direction of the synchronizing member 61. However, by rotating the support part 2, the several air guide plates 5 can guide the airflow in different directions.

[0027] Furthermore, the positioning component 6 includes a synchronizing element 61, and several air guide plates 5 are linearly and equidistantly arranged. Both sides of the air guide plates 5 are rotatably connected to the opening side of the support part 2 via a rotating shaft. The synchronizing element 61 is disposed at the bottom of the air guide plates 5, and the synchronizing element 61 and the several air guide plates 5 are arranged in a cross pattern.

[0028] More specifically, the air guide plate 5 is fixedly connected to a rotating shaft within the bottom slide groove 51, and the synchronizing element 61 is movably connected within the slide groove 51 and rotatably connected to the rotating shaft.

[0029] In general, the positioning component 6 also includes an elastic element 62. The support part 2 has a cavity 21 in the protruding part on the opening side. A plurality of positioning protrusions 63 are distributed circumferentially on the inner wall of the cavity 21. The elastic element 62 is rotatably connected in the cavity 21 and fixedly connected to the rotating shaft of one of the air guide plates 5.

[0030] Finally, the elastic member 62 has several deformation grooves 64 extending through both sides, and the elastic member 62 has protrusions 65 corresponding to the deformation grooves 64 distributed around its outer circumference. The protrusions 65 slide against the positioning protrusions 63 through the deformation grooves 64, and the protrusions 65 also stop between two adjacent positioning protrusions 63.

[0031] In this embodiment, the air guide plate 5 is opened and closed synchronously and in the same direction through the synchronization member 61. For details, please refer to the wind deflector structure of the vehicle air outlet in the prior art.

[0032] Specifically, the elastic element 62 is preferably made of a material with deformation capability such as rubber or plastic, and the shaft end of one of the air guide plates 5 is rotatably connected in the cavity 21, and the shaft end is also fixedly connected to the elastic element 62.

[0033] More specifically, during the rotation of the elastic member 62, the protrusion 65 slides against the positioning protrusion 63 under the action of the deformation groove 64, and several air guide plates 5 rotate synchronously through the synchronizing member 61, so that when one air guide plate 5 rotates, the remaining air guide plates 5 can rotate synchronously.

[0034] Similarly, after one of the air guide plates 5 is fixed, the remaining air guide plates 5 are also fixed due to the synchronization component 61. When the protrusion 65 stops between two adjacent positioning protrusions 63, the air blowing angle can be fixed. In addition, the protrusion 65 slides against the positioning protrusions 63, which can adjust the air blowing angle in multiple levels.

[0035] Working method: During operation, the screw 41 is rotated by the butterfly part 42. After the end of the screw 41 is separated from the support part 2, the support part 2 and several air guide plates 5 can be rotated. After the air guiding direction of the air guide plate 5 is determined, the screw 41 is locked to fix the support part 2.

[0036] When one of the air guide plates 5 is rotated, the remaining air guide plates 5 rotate synchronously and in the same direction under the action of the synchronizing member 61, and at the same time as the air guide plate 5 rotates, the elastic member 62 rotates synchronously with the rotating shaft of the air guide plate 5.

[0037] The protrusion 65 slides against the positioning protrusion 63 through the deformation groove 64. The protrusion 65 stops between two adjacent positioning protrusions 63, thus fixing the flip angle of the air guide plate 5, i.e. the air guide angle.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
