Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of axial flow fan technology, and more specifically, to a detachable axial flow fan impeller. Background Technology

[0002] The impeller of an axial flow fan is the core component of an axial flow fan, responsible for generating airflow and driving air or gas through the fan. Its structural design determines the fan's performance, including air volume, pressure, and efficiency. The working principle of an axial flow fan impeller is to transmit power to the air or gas through the rotation of the blades, causing it to flow axially.

[0003] According to a public disclosure of an axial flow fan impeller (publication number: CN 211343481U): it includes a hub, the outer periphery of the blade hub is provided with a mounting groove, the top surface of the mounting groove is provided with a scale, a blade stalk is detachably installed in the mounting groove, the blade stalk includes a protrusion located outside the mounting groove, the protrusion is provided with a pointer, and a fan blade is provided on the outer side of the protrusion.

[0004] In the aforementioned application, the interaction between the blade hub and the blade shank assembly makes it difficult to stabilize the blade shank after it is positioned and installed. Simply fixing it with bolts causes the threads of the blade shank to loosen during long-term operation. Therefore, we propose a detachable axial flow fan impeller. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a detachable axial flow fan impeller, which solves the problem in the related art that the impeller and blades cannot be stably installed and disassembled.

[0006] According to one aspect, at least one embodiment of the present disclosure provides a detachable axial flow fan impeller, including rotating blades, wherein the circumferential surface of the rotating blades is provided with an installation and disassembly mechanism;

[0007] The installation and disassembly mechanism includes a rotating shaft, an impeller disk mounted on the circumferential surface of the rotating shaft, a positioning groove plate fixedly connected to the circumferential surface of the impeller disk, a support shaft rotatably connected inside the positioning groove plate, a force-bearing plate fixedly connected to the circumferential surface of the support shaft, a clamping plate fixedly connected to the circumferential surface of the support shaft, one end of the rotating blade slidably connected inside the positioning groove plate, and a clamping groove is provided on the side of the rotating blade.

[0008] For example, in at least one embodiment of this disclosure, a detachable axial flow fan impeller is provided, which further includes: a torsion spring fixedly connected inside the positioning groove plate, and one end of the torsion spring away from the inside of the positioning groove plate is fixedly connected to the circumferential surface of the support shaft. The purpose is to ensure that the clamping plate can automatically reset and reduce manual intervention.

[0009] The rotating blade has a locking groove on its side, and the positioning slot plate has a fixing hole on its side, with a fixing stud connected to the inside of the fixing hole by a thread.

[0010] The locking groove has the same diameter as the fixing stud.

[0011] The number of positioning slot plates, clamping plates and rotating blades is set to several, and they are arranged in a circumferential array along the circumference of the impeller disk. The top of the force plate is located on the displacement trajectory of the rotating blades.

[0012] According to another aspect, at least one embodiment of this disclosure also provides a detachable axial flow fan impeller, further comprising a spray mechanism, the spray mechanism including a belt and a storage box, a control shaft rotatably connected inside the storage box, a half gear fixedly passing through the circumferential surface of the control shaft, a sliding groove provided inside the storage box, a rack slidably connected inside the sliding groove, a water tank fixedly connected inside the storage box, an extrusion plate slidably connected inside the water tank, a moving rod fixedly connected to the side of the extrusion plate, and a conveying pipe fixedly passing through the side of the water tank.

[0013] For example, in at least one embodiment of this disclosure, a detachable axial flow fan impeller is provided, which further includes: a return spring fixedly connected to the side of the rack, and the end of the return spring away from the side of the rack is fixedly connected to the inside of the storage box.

[0014] A tension spring is fixedly connected to the side of the extrusion plate, and the end of the tension spring away from the side of the extrusion plate is fixedly connected to the inner wall of the water tank.

[0015] The number of spray holes is set to several.

[0016] The circumferential surface of the half gear meshes with the side surface of the rack, and one end of the moving rod is located on the displacement trajectory of the rack.

[0017] The beneficial effects of the embodiments disclosed herein are as follows:

[0018] 1. In this utility model, through the cooperation between components such as the impeller disk, rotating blades, and locking holes in the installation and disassembly mechanism, when the impeller disk inside the axial flow fan needs to be installed, the operator first inserts the rotating blade into the positioning slot plate, presses the rotating blade, and the clamping plate rotates into the clamping slot to position and clamp the rotating blade. At this time, the locking slot coincides with the fixing hole, and the operator uses the fixing stud to pass through the locking slot to stably install the rotating blade. Finally, by starting the motor, the output shaft of the motor rotates, driving the rotating shaft to rotate, and the rotating shaft drives the impeller disk and rotating blades to work. This design achieves the effect of installing and disassembling the impeller and blades, effectively reducing maintenance time and costs.

[0019] 2. In this utility model, through the mutual cooperation between components such as the half gear, water tank and spray hole of the spray mechanism, the rotating shaft rotates while the control shaft rotates via the belt. The rotation of the control shaft drives the half gear to rotate. Through the meshing of the half gear and the rack, the water flow inside the water tank is pressurized and enters the conveying chamber through the conveying pipe. Then it is sprayed out through the spray hole to form a fine water mist. This design achieves the effect of spraying the air, using spray cooling to improve production efficiency and comfort.

[0027] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0028] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0029] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0031] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.

[0032] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0033] like Figures 1-5 As shown, it illustrates a detachable axial flow fan impeller in one embodiment of the present disclosure, including rotating blades 57, and an installation and removal mechanism 5 is provided on the circumferential surface of the rotating blades 57;

[0034] The installation and disassembly mechanism 5 includes a rotating shaft 51, an impeller disk 52 mounted on the circumferential surface of the rotating shaft 51, a positioning groove plate 53 fixedly connected to the circumferential surface of the impeller disk 52, a support shaft 54 ​​rotatably connected inside the positioning groove plate 53, a force-bearing plate 55 fixedly connected to the circumferential surface of the support shaft 54, a clamping plate 56 fixedly connected to the circumferential surface of the support shaft 54, one end of a rotating blade 57 slidably connected inside the positioning groove plate 53, and a clamping groove 58 is provided on the side of the rotating blade 57.

[0035] The rotating shaft 51 is fixedly installed on the rotating shaft of the motor 4. The motor 4 is fixedly connected to the side of the fixing frame 3. The fixing frame 3 is fixedly connected to the inside of the housing 1. The bottom of the housing 1 is fixedly connected to the bracket 2.

[0036] In some examples, a torsion spring 59 is fixedly connected inside the positioning slot plate 53. One end of the torsion spring 59 away from the inside of the positioning slot plate 53 is fixedly connected to the circumferential surface of the support shaft 54. The purpose is to ensure that the clamping plate 56 can automatically reset and reduce manual intervention.

[0037] The rotating blade 57 has a locking groove 510 on its side, and the positioning groove plate 53 has a fixing hole 511 on its side. The fixing hole 511 is internally threaded with a fixing stud 512, the purpose of which is to stably install the rotating blade 57 after positioning.

[0038] A protective cover 513 is installed on the front side of the housing 1, and a dust cover 514 is fixedly connected to the rear side of the housing 1. The locking groove 510 has the same diameter as the fixing stud 512. The purpose is to protect and prevent dust from the components working inside the housing 1.

[0039] The number of positioning slot plates 53, clamping plates 56 and rotating blades 57 is set in a number and arranged in a circumferential array along the circumference of the impeller disk 52. The top of the force plate 55 is located on the displacement trajectory of the rotating blades 57. The purpose is to enable the individual rotating blades 57 to be disassembled independently, thus saving maintenance costs.

[0040] For example, such as Figures 1-5As shown, when it is necessary to install the impeller disk 52 inside the axial flow fan, the operator first inserts the rotating blade 57 into the positioning slot plate 53, presses the rotating blade 57 so that the rotating blade 57 is against the top of the force plate 55, the force plate 55 is subjected to force and rotates through the support shaft 54, the rotation of the support shaft 54 ​​drives the clamping plate 56 to rotate, the clamping plate 56 rotates into the clamping slot 58 to position and clamp the rotating blade 57. At this time, the locking slot 510 coincides with the fixing hole 511, and the operator uses the fixing stud 512 to pass through the locking slot 510 to stably install the rotating blade 57. Finally, the impeller disk 52 is installed on the circumference of the rotating shaft 51, and the motor 4 is started. The output shaft of the motor 4 rotates and drives the rotating shaft 51 to work. The rotating shaft 51 rotates and drives the impeller disk 52 and the rotating blade 57 to work. The rotating blade 57 is protected by the protective cover 513 during operation.

[0041] like Figures 1-5 As shown, this illustration depicts a detachable axial flow fan impeller in another embodiment of this disclosure. It is largely the same as the technical solution described above, so only the differences are emphasized. The impeller includes a spray mechanism 6, which comprises a belt 61 disposed on the circumferential surface of a rotating shaft 51. A storage box 62 is fixedly connected to the bottom of the housing 1. A control shaft 63 is rotatably connected inside the storage box 62. A half-gear 64 is fixedly passed through the circumferential surface of the control shaft 63. A sliding groove 65 is provided inside the storage box 62, and a rack 66 is slidably connected inside the sliding groove 65. A water tank 67 is fixedly connected inside the storage box 62, and a pressing plate 68 is slidably connected inside the water tank 67. A moving rod 69 is fixedly connected to the side of the pressing plate 68, and a conveying pipe 610 is fixedly passed through the side of the water tank 67. A conveying chamber 611 is provided inside the housing 1, and spray holes 612 are provided on the side of the housing 1. The purpose of these features is to cool the air and increase humidity, thus improving air quality.

[0042] In some examples, a return spring 613 is fixedly connected to the side of the rack 66. The end of the return spring 613 away from the side of the rack 66 is fixedly connected to the inside of the storage box 62. The purpose is to ensure that the rack 66 can automatically reset and reduce manual intervention.

[0043] A tension spring 614 is fixedly connected to the side of the extrusion plate 68. The end of the tension spring 614 away from the side of the extrusion plate 68 is fixedly connected to the inner wall of the water tank 67. The purpose is to ensure that the extrusion plate 68 can be reset and reduce manual intervention.

[0044] The number of spray holes 612 is set to several, and they are symmetrical about each other along the numerical central axis of the housing 1. The circumferential surface of the rotating shaft 51 is connected to the circumferential surface of the control shaft 63 through the belt 61, which is intended to improve the spraying effect.

[0045] The circumferential surface of the half gear 64 meshes with the side surface of the rack 66, and one end of the moving rod 69 is located on the displacement trajectory of the rack 66. The purpose is to ensure that the rotation of the half gear 64 can drive the rack 66 to move, and the movement of the rack 66 can push the moving rod 69.

[0046] For example, such as Figures 1-5 As shown, while the rotating shaft 51 rotates, it drives the control shaft 63 to rotate via the belt 61. The rotation of the control shaft 63 drives the half gear 64 to rotate. The half gear 64 meshes with the rack 66, causing the rack 66 to move inside the slide groove 65. The movement of the rack 66 pushes the moving rod 69. The moving rod 69, under force, drives the extrusion plate 68 to move inside the water tank 67. At this time, the water inside the water tank 67 is pressurized and enters the conveying chamber 611 through the conveying pipe 610. Then, it is sprayed out through the spray hole 612 to form a fine water mist, thereby achieving air humidity regulation or cooling. When the half gear 64 continues to rotate, it rotates to the toothless area. The rack 66 is reset by the return spring 613, and the extrusion plate 68 is reset by the tension spring 614, thus causing the water mist to be sprayed out intermittently.

[0047] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
