Description

Technical Field

[0001] This utility model relates to the field of axial flow fan technology, and specifically to an axial flow fan ventilation structure. Background Technology

[0002] Axial flow fans, as a type of ventilation equipment with a compact structure, large air volume, and relatively low cost, are widely used in many fields such as heat dissipation, ventilation, cooling, and purification of electronic equipment. Their core working principle is to use rotating blades to apply axial thrust to the air, causing the air to flow along the fan axis.

[0003] The existing axial flow fans are fixed, and their ventilation structure is along a single radial direction of the air duct. Changing the airflow direction requires moving and turning the entire fan, which is quite inconvenient during use and limits the application of axial flow fans. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides an axial flow fan ventilation structure, which solves the problem of inconvenient operation such as wind direction adjustment due to the single radial direction of the ventilation structure along its duct.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an axial flow fan ventilation structure, including a fan housing and an air supply component, further including a slide rail, a baffle plate, a tilting limiting component, and a rotating limiting component. The air supply component is disposed inside the fan housing. The slide rail is fixedly installed at both ends of the fan housing. The baffle plate is located at the front and rear inlets and outlets of the fan housing. The baffle plate and the tilting limiting component are rotatably connected. The tilting limiting component is slidably installed on the surface of the slide rail. The rotating limiting component is hingedly installed on the surface of the tilting limiting component, and the rotating limiting component is slidably inserted into both ends of the fan housing.

[0006] The fan casing includes a casing, a support base, a protective net, and slots. The support base is fixedly installed at the bottom of the casing, the protective net is fixedly installed on the inner wall of the casing and located at the air inlet and outlet of the casing, and slots are provided at both the front and rear ends of the casing.

[0007] The slide rail includes a fixing ring and a limiting groove. The fixing ring is fixedly installed on the front and rear sides of the fan casing and surrounds the inlet and outlet of the fan casing. A limiting groove is provided on the side of the fixing ring away from the casing.

[0008] The wind deflector includes a semi-circular disc and a rotating shaft. The semi-circular disc is fixedly installed on one side of the rotating shaft, with one end of the semi-circular disc located at the center of the rotating shaft, and the other end connected to the flip-limiting component.

[0009] The number of wind deflectors is four sets, which are symmetrically arranged in pairs at the front and rear ends of the fan casing. The adjacent sets of wind deflectors are centrally symmetrical, and the two sets of semicircular discs are on the same axis and are rotatably connected.

[0010] The flipping limiting component includes a fixed plate, a slider, a worm gear, a worm, and a handle. The fixed plate is slidably sleeved on one end of the wind deflector. The slider is fixedly installed on one side of the fixed plate and is slidably installed inside the slide rail. The worm gear is rotatably installed inside the fixed plate, and one end of the worm gear is fixedly connected to one end of the wind deflector. The worm is rotatably installed inside the fixed plate, and the worm and the worm gear are meshed. The handle is fixedly installed on one end of the worm.

[0011] The rotating limiting component includes a clamping plate and a magnetic block. The clamping plate is hinged to the surface of the fixed plate, and the magnetic block is embedded in one end of the clamping plate. The clamping plate and the magnetic block are slidably inserted into the front and rear edges of the fan housing.

[0012] The rotating limiting component is correspondingly set with the slot, and there are multiple sets of slots, which are arranged in a circular array along the front and rear edges of the fan casing.

[0013] The beneficial effects of this utility model are as follows:

[0014] This invention controls the rotation of the shaft by turning the handle, which in turn drives the worm gear meshing with it to rotate. The worm gear then drives the connected semi-circular disk to rotate, thereby controlling the shaft's rotation and adjusting its tilt angle. The cooperation between the worm gear and the worm gear limits the rotation of the shaft. Pushing the fixed plate causes the slider to slide along the inside of the limiting groove, thus controlling the shaft's rotation. The magnetic block attracts the barrel, causing the card plate to insert into the card slot, further limiting the shaft's rotation. By controlling the rotation of the baffle plate at the barrel's air inlet, the device can easily change its air intake direction, allowing for focused air extraction on one side. Similarly, by controlling the rotation of the baffle plate at the barrel's air outlet, the device can easily change its air outlet direction, redirecting the airflow from forward along the axis to blowing to both sides, or focusing on blowing on one side. Adjusting the baffle plate to be perpendicular to the front and rear sides of the fan casing allows the device to operate normally in the front-to-back direction for air extraction and blowing.

[0021] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0022] Figures 1-5 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figure 1 -Appendix Figure 5 The present invention will be further described below.

[0023] An axial flow fan ventilation structure includes a fan housing 1 and an air supply assembly 2, as well as a slide rail 3, a baffle plate 4, a tilting limiter 5, and a rotation limiter 6. The air supply assembly 2 is disposed inside the fan housing 1. The slide rail 3 is fixedly installed at the front and rear ends of the fan housing 1. The baffle plate 4 is located at the front and rear inlet and outlet of the fan housing 1. The baffle plate 4 is rotatably connected to the tilting limiter 5. The tilting limiter 5 is slidably installed on the surface of the slide rail 3. The rotation limiter 6 is hingedly installed on the surface of the tilting limiter 5, and the rotation limiter 6 is slidably inserted into the front and rear ends of the fan housing 1.

[0024] Specifically, the air supply component 2 drives air to enter through the rear air inlet of the fan housing 1 and then exit through the front air outlet of the fan housing 1. The component consisting of the wind deflector 4, the flip limiter 5, and the rotation limiter 6 is supported by the slide rail 3 to rotate stably. The wind deflector 4 blocks the front and rear inlets and outlets of the fan housing 1 to control the size of its ventilation surface. The flip limiter 5 controls the flipping of the wind deflector 4, and the rotation limiter 6 restricts the rotation of the wind deflector 4.

[0025] The fan housing 1 includes a casing 101, a support base 102, a protective net 103, and a slot 104. The support base 102 is fixedly installed at the bottom of the casing 101, the protective net 103 is fixedly installed on the inner wall of the casing 101 and located at the air inlet and outlet of the casing 101, and slots 104 are provided at both the front and rear ends of the casing 101.

[0026] Specifically, the protective net 103 protects the inlet and outlet at both ends of the barrel 101, preventing objects and personnel from entering the barrel 101 and contacting the air supply component 2 when the device is in operation. The rotation of the baffle plate 4 is limited and fixed by the connection between the slot 104 and the rotation limiter 6.

[0027] The slide rail 3 includes a fixing ring 301 and a limiting groove 302. The fixing ring 301 is fixedly installed on the front and rear sides of the machine barrel 101 and surrounds the inlet and outlet of the machine barrel 101. The limiting groove 302 is provided on the side of the fixing ring 301 away from the machine barrel 101.

[0028] Specifically, the limiting groove 302 restricts the sliding of the flip-stopping member 5 inside, so that the wind deflector 4 can be stably rotated and adjusted at the inlet and outlet of the front and rear ends of the fan housing 1.

[0029] The wind deflector 4 includes a semi-circular disc 401 and a rotating shaft 402. The semi-circular disc 401 is fixedly installed on one side of the rotating shaft 402. One end of the semi-circular disc 401 is located at the center of the rotating shaft 402, and the other end is connected to the flipping limit member 5.

[0030] Specifically, the rotating shaft 402 is supported by the semi-circular disk 401, which causes the rotating shaft 402 to flip and adjust its angle with the horizontal planes on the front and rear sides of the drive.

[0031] There are four sets of wind deflectors 4, which are symmetrically arranged in pairs at the front and rear ends of the fan housing 1. The two sets of wind deflectors 4 are centrally symmetrical, and the two sets of semicircular discs 401 are on the same axis and are rotatably connected.

[0032] Specifically, the airflow entering the fan housing 1 is controlled by two sets of baffles 4 located at the rear end of the fan housing 1, and the airflow exiting the fan housing 1 is controlled by two sets of baffles 4 located at the front end of the fan housing 1. The inlet and outlet airflow of the fan housing 1 is divided by two symmetrically connected sets of baffles 4, causing it to deflect to both sides or deflect mainly to one side.

[0033] The flipping limiting component 5 includes a fixed plate 501, a slider 502, a worm gear 503, a worm 504, and a handle 505. The fixed plate 501 is slidably sleeved on one end of the semi-circular disk 401 away from the center of the rotating shaft 402. The slider 502 is fixedly installed on one side of the fixed plate 501 that is in contact with the fixed ring 301, and the slider 502 is slidably installed inside the limiting groove 302. The worm gear 503 is rotatably installed inside the fixed plate 501, and one end of the worm gear 503 is fixedly connected to one end of the semi-circular disk 401. The worm 504 is rotatably installed inside the fixed plate 501, and the worm 504 is meshed with the worm gear 503. The handle 505 is fixedly installed on one end of the worm 504.

[0034] Specifically, the slider 502 slides inside the limiting groove 302, causing the component connected to the slider 502 to rotate around the center of the fixed ring 301. The handle 505 controls the rotation of the worm 504, which drives the worm wheel 503 to rotate, causing the wind deflector 4 connected to the worm wheel 503 to flip. The cooperation between the worm wheel 503 and the worm 504 restricts the free flipping of the semi-circular disk 401.

[0035] The rotating limiting component 6 includes a clamping plate 601 and a magnetic block 602. The clamping plate 601 is hinged to the surface of the fixing plate 501, and the magnetic block 602 is embedded in one end of the clamping plate 601. The clamping plate 601 and the magnetic block 602 are slidably inserted into the front and rear edges of the fan housing 1.

[0036] Specifically, the card plate 601 rotates on the surface of the fixing plate 501, moving it away from or inserting it into the card slot 104, thereby releasing the rotation limit on the wind deflector 4 or fixing it. The magnetic block 602 attracts and fixes the fan housing 1, so that the card plate 601 can be tightly attached to the inner wall of the card slot 104.

[0037] The rotating limiting component 6 is correspondingly set with the slot 104. There are multiple sets of slots 104, which are arranged in a circular array along the front and rear edges of the fan housing 1. The card plate 601 is attached to the inner wall of the slot 104, and the magnetic block 602 is located on the side of the card plate 601 near the slot 104.

[0038] Specifically, the rotation angle of the wind deflector 4 is easily adjusted by correspondingly inserting multiple sets of slots 104 into the rotation limiter 6.

[0039] In summary: When using this utility model, if it is necessary to focus on exhausting air from a certain side during the air supply operation, operate the flip-up limiting member 5 and the rotation limiting member 6 on the rear side of the fan housing 1. Flip the card plate 601 to disengage the magnetic block 602 from the inside of the slot 104, release the rotation limiting member 6 from the rotation limit of the baffle plate 4, push the flip-up limiting member 5 to make the slider 502 slide inside the limiting groove 302, control the rotation of the baffle plate 4 to the appropriate position, then flip the card plate 601 to insert into the slot 104 so that the magnetic block 602 fixes the card plate 601 into the slot 104, limiting the rotation of the baffle plate 4. Then turn the handle 505 to drive the worm gear 504 to rotate, the worm gear 504 drives the meshing worm wheel 503 to rotate, and the worm wheel 503 drives the connected semi-circular disk 401. Rotation causes a set of rotating shafts 402 to engage with the fixed ring 301, remaining parallel to the rear side of the fan housing 1, thus closing that side and allowing the device to focus on air extraction from the other side. If it is necessary to focus on air delivery to one side or both sides, operate the flip-limiting part 5 and the rotation-limiting part 6 on the front side of the fan housing 1 to rotate and flip the baffle plate 4, closing one side of the rotating shaft 402 to focus on air delivery to the other side, and opening both sides of the rotating shaft 402 to adjust their angle with the front and rear sides of the fan housing 1, thereby changing the direction of airflow to both sides. If it is necessary to perform normal air extraction and delivery in the front and rear direction, adjust the two sets of rotating shafts 402 on the front and rear sides of the fan housing 1 to engage with each other, making them perpendicular to the front and rear sides of the fan housing 1, to prevent the rotating shafts 402 from changing the direction of airflow in and out of the device.

[0040] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
