Description

Technical Field

[0001] The present invention relates to the technical field related to folding fans, and in particular to a high-power fan structure with a foldable base and a base folding method thereof. Background Art

[0002] High-power fans are widely used in a variety of fields. Their key features include high air volume, low energy consumption, high efficiency, and significantly improved work environment comfort. They are widely used in large industrial sites such as factories, warehouses, stations, and airports. These locations are often vast and contain tall spaces, making traditional ventilation equipment inadequate. High-power fans, with their large-diameter blade design and high-efficiency motors, generate high air volume at low speeds, effectively covering the entire space and creating air circulation, solving ventilation and cooling issues while also reducing energy consumption.

[0003] At present, with the popularization of high-power fans, fan structures are gradually improved in technology. Among them, the fan structure is combined with a folding method to reduce the occupied space to facilitate handling and transportation. However, when unfolding and storing the folding fan, it is basically controlled manually, resulting in insufficient support stability at the bottom of the fan to support the operation of the fan after unfolding, causing the fan to easily fall over and have low stability. Summary of the Invention

[0004] The object of the present invention is to provide a high-power fan structure with a foldable base to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions: A high-power fan structure with a foldable base comprises a support base, wherein a plurality of support legs are provided along the circumference of the support base, the support legs are rotatably connected to the support base and can be folded into a storage groove formed by the support base; It also includes a receiving sleeve and a receiving rod, the receiving sleeve and the receiving rod are arranged along the axial direction of the support seat, one end of the receiving sleeve is fixedly connected to the support seat, and the other end is slidably connected to the receiving rod, and a fan is installed on the receiving rod; The adjustment mechanism includes a first adjustment member and a second adjustment member arranged in the receiving sleeve. The first adjustment member can control the rotation of the support leg relative to the support seat, and the second adjustment member can change the support radius of the support leg. When the receiving rod moves relative to the receiving sleeve, the first adjustment member and the second adjustment member are driven to work respectively.

[0006] The high-power fan structure with a foldable base as described above: the support leg includes a support plate rotatably connected to the storage slot, an embedded groove is formed at the end of the support plate, an extension plate is slidably arranged in the embedded groove, a pillar that can abut against the ground is fixedly arranged on the extension plate, and the movement of the extension plate is controlled by a threaded pusher arranged in the support plate.

[0007] The high-power fan structure with a foldable base as described above: the threaded pusher includes a screw rod rotatably mounted on the support plate, one end of the screw rod is threadedly connected to the extension plate, and the other end passes through the support plate and is provided with a second bevel gear.

[0008] The high-power fan structure with a foldable base as described above: the first adjusting member includes a first transmission rod rotatably installed in the receiving sleeve, one end of the first transmission rod is formed with a first limiting groove, and the other end is formed with an external thread and is threadedly connected to a threaded sleeve slidably arranged in the receiving sleeve, the threaded sleeve is arranged along the circumference and hinged with multiple connecting rods, and the end of the connecting rod away from the threaded sleeve is hinged to the support plate.

[0009] The high-power fan structure with a foldable base as described above: the second adjusting member includes a second transmission rod arranged in the receiving sleeve, the second transmission rod is arranged along the axial direction of the first transmission rod and passes through the first transmission rod, and a second limiting groove is formed at one end of the second transmission rod inserted into the receiving rod, and a first bevel gear that can engage with the second bevel gear is provided on the other end of the second transmission rod.

[0010] As described above, in the high-power fan structure with a foldable base, a cylindrical cavity is formed in the receiving rod, and a first ball and a second ball adapted to the first limiting groove and the second limiting groove are respectively rollingly arranged in the cylindrical cavity.

[0011] The high-power fan structure with a foldable base as described above: a limit ring is rotatably provided on the receiving sleeve, and a plurality of locking members are equidistantly provided on the limit ring along the circumference, and the locking members can be inserted into the lock holes formed on the outer wall of the receiving rod.

[0012] The high-power fan structure with a foldable base as described above: the locking member includes a plug-in post, the plug-in post is slidably connected to the plug-in groove formed on the inner wall of the limiting ring, and a third ball that can be inserted into the lock hole is rollingly provided on the end of the plug-in post away from the plug-in groove; It also includes a spring, which is arranged in the plug-in slot, with one end of the spring abutting against the end of the plug-in slot and the other end abutting against the plug-in column.

[0013] A method for folding a base of a high-power fan structure, using any one of the above-mentioned high-power fan structures with a foldable base, comprises the following steps: Step 1: Before using the fan, manually release the folded state of the receiving sleeve and the receiving rod. First, control the limit ring to rotate relative to the receiving rod to release the locking work of the receiving rod; Step 2: driving the receiving rod to move relative to the receiving sleeve, and controlling the first adjusting member to operate while the receiving rod moves, so as to squeeze the plurality of supporting legs and simultaneously rotate them relative to the supporting base; Step 3: After the support legs are rotated to contact the ground, when the support height of the fan needs to be adjusted, the receiving rod is driven to move again to control the second adjustment member to work, so as to change the support radius of the support legs.

[0014] Compared with the prior art, the present invention has the following beneficial effects: The fan is released from its folded state by manually controlling the receiving rod to move relative to the receiving sleeve. When the receiving rod moves, the first adjusting member and the second adjusting member are controlled to operate respectively, so that when the first adjusting member rotates, the supporting leg can be squeezed to rotate relative to the supporting seat until the supporting leg is flush with the bottom of the supporting seat. When the support height of the fan is adjusted, the second adjusting member can be driven to operate to change the support radius of the supporting leg, effectively reducing the storage space of the fan while enhancing the overall stability of the fan when it is in the folded state, and avoiding the fan from tipping over due to unstable center of gravity after the height is changed, ensuring that the fan as a whole always maintains a stable support state when it is working.

[0027] Various exemplary embodiments, features, and aspects of the present application will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise indicated.

[0028] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0029] In addition, numerous specific details are provided in the following specific examples to better illustrate the present application. Those skilled in the art will appreciate that the present application can be practiced without certain specific details. In some instances, methods, means, and components well known to those skilled in the art are not described in detail in order to highlight the main purpose of the present application.

[0030] See also Figures 1 to 11In an embodiment of the present invention, a high-power fan structure with a foldable base includes a support base 1, wherein a plurality of support legs are provided along a circumference of the support base 1, and the support legs are rotatably connected to the support base 1 and can be folded into a storage groove 101 formed in the support base 1; It also includes a receiving sleeve 2 and a receiving rod 3, the receiving sleeve 2 and the receiving rod 3 are arranged along the axial direction of the support base 1, one end of the receiving sleeve 2 is fixedly connected to the support base 1, and the other end is slidably connected to the receiving rod 3, and a fan is installed on the receiving rod 3; The adjustment mechanism includes a first adjustment member and a second adjustment member arranged in the receiving sleeve 2. The first adjustment member can control the rotation of the support leg relative to the support seat 1, and the second adjustment member can change the support radius of the support leg. When the receiving rod 3 moves relative to the receiving sleeve 2, the first adjustment member and the second adjustment member are driven to work respectively.

[0031] In detail, before the fan is used, the receiving rod 3 is manually controlled to move relative to the receiving sleeve 2 to release the fan from its folded state. When the receiving rod 3 moves, the first adjusting member and the second adjusting member are controlled to work respectively. When the first adjusting member rotates, it can squeeze the support leg to rotate relative to the support base 1 until the support leg is flush with the bottom of the support base 1. When the support height of the fan is adjusted, the second adjusting member can be driven to work to change the support radius of the support leg, which effectively reduces the storage space of the fan while enhancing the overall stability of the fan when it is in the folded state. When the support height of the fan changes, its overall center of gravity shifts, and the support radius of its bottom can follow the change to avoid the fan from tipping over due to unstable center of gravity after the height changes, ensuring that the fan as a whole always maintains a stable support state when it is working.

[0032] Preferably, a guide groove 201 is formed on the inner wall of the receiving sleeve 2 , and a guide block 302 that slides with the guide groove 201 is provided on the outer wall of the receiving rod 3 .

[0033] For further details of the present invention, please refer to Figure 1 and Figure 11 The support leg includes a support plate 12 rotatably connected to the storage slot 101, and an embedded groove is formed at the end of the support plate 12. An extension plate 13 is slidably arranged in the embedded groove, and a support 14 that can abut against the ground is fixedly arranged on the extension plate 13, and the movement of the extension plate 13 is controlled by a threaded pusher arranged in the support plate 12.

[0034] The threaded pusher includes a screw rod 15 rotatably mounted on the support plate 12 . One end of the screw rod 15 is threadedly connected to the extension plate 13 , and the other end passes through the support plate 12 and is provided with a second bevel gear 16 .

[0035] In the initial state, the support legs are completely folded in the storage slots 101, which reduces the space occupied and facilitates transportation and handling. When the fan needs to be supported, the receiving rod 3 is moved upward relative to the receiving sleeve 2. The receiving rod 3 moves upward and the first adjustment member is driven to work. Under the push of the first adjustment member, multiple support legs are flipped outward at the same time until the bottom of the pillar 14 can abut against the ground, so as to release the folded state of the bottom of the fan and ensure stable support of its bottom when the fan is working.

[0036] As a further solution of the present invention, please refer to Figure 6 and Figure 7 The first adjusting member includes a first transmission rod 7 rotatably installed in the socket sleeve 2, one end of the first transmission rod 7 is formed with a first limiting groove 701, and the other end is formed with an external thread and is threadedly connected to a threaded sleeve 9 slidingly arranged in the socket sleeve 2. The threaded sleeve 9 is arranged along the circumference and is hinged with multiple connecting rods 11. The end of the connecting rod 11 away from the threaded sleeve 9 is hinged to the support plate 12.

[0037] The second adjusting member includes a second transmission rod 8 arranged in the receiving sleeve 2. The second transmission rod 8 is arranged along the axial direction of the first transmission rod 7 and passes through the first transmission rod 7. A second limiting groove 801 is formed at one end of the second transmission rod 8 inserted into the receiving rod 3. The other end of the second transmission rod 8 is provided with a first bevel gear 10 that can engage with the second bevel gear 16.

[0038] A cylindrical cavity is formed in the receiving rod 3 , and a first ball 303 and a second ball 304 adapted to the first limiting groove 701 and the second limiting groove 801 are respectively rollingly arranged in the cylindrical cavity.

[0039] Preferably, at least one group of strip blocks 901 are provided on the threaded sleeve 9, and a strip groove slidably connected to the strip blocks 901 is formed in the support seat 1 to limit the threaded sleeve 9 from and enable it to move linearly along the axis direction of the first transmission rod 7.

[0040] Preferably, the first limiting groove 701 is divided into an A thread groove and an A linear groove, and the second limiting groove 801 is divided into a B linear groove and a B thread groove.

[0041] In the initial state, the first ball 303 is located in the thread groove A and the second ball 304 is located in the linear groove B. When the receiving rod 3 is manually controlled to move upward relative to the receiving sleeve 2, the first ball 303 generates an inclined force on the thread groove A, causing the first transmission rod 7 to rotate. When the first transmission rod 7 rotates, it drives the threaded sleeve 9 to move linearly along the axis direction of the first transmission rod 7. When the threaded sleeve 9 moves downward, it drives multiple connecting rods 11 to simultaneously deflect the support plate 12 hinged thereto relative to the storage groove 101. When the first ball 303 moves to the end of the thread groove A, the deflection angle of the support leg reaches 90°. At this time, the bottom surface of the pillar 14 can abut against the ground to completely release the folding state of the support leg, so that the overall support stability of the bottom of the fan is improved when it is working.

[0042] Among them, after the supporting legs are fully extended, when the supporting height of the receiving rod 3 needs to be adjusted, the receiving rod 3 can be driven up again relative to the receiving sleeve 2. At this time, the first ball 303 moves to the A linear groove, and the second ball 304 moves to the B thread groove. The upward movement of the receiving rod 3 cannot cause the rotation of the first transmission rod 7, and the second ball 304 produces a tilting force on the B thread groove, causing the second transmission rod 8 to rotate. At this time, the first bevel gear 10 and the second bevel gear 16 are in a meshing state. When the second transmission rod 8 rotates, it drives the screw rod 15 to rotate under the transmission of the first bevel gear 10 and the second bevel gear 16, and when the screw rod 15 rotates, it drives the extension plate 13 to make a linear motion along the axial direction of the screw rod 15, so as to realize the sliding of the extension plate 13 relative to the support plate 12, ensuring that when the support height of the fan changes, the support radius of its bottom is adjusted synchronously to ensure that the overall support stability remains unchanged when the fan is working.

[0043] As a further solution of the present invention, please refer to Figure 3 and Figure 4 A limiting ring 4 is rotatably provided on the receiving sleeve 2 , and a plurality of locking members are equidistantly provided on the limiting ring 4 along the circumference, and the locking members can be inserted into the locking hole 301 formed on the outer wall of the receiving rod 3 .

[0044] The locking member includes a plug-in column 5, which is slidably connected to the plug-in groove 401 formed on the inner wall of the limiting ring 4, and a third ball 501 that can be inserted into the lock hole 301 is rollingly provided on the end of the plug-in column 5 away from the plug-in groove 401; It also includes a spring 6 , which is disposed in the plug-in slot 401 , with one end of the spring 6 abutting against the end of the plug-in slot 401 , and the other end abutting against the plug-in post 5 .

[0045] Preferably, a plurality of locking holes 301 are distributed along the circumference on the outer wall of the receiving rod 3 , and the locking holes 301 are distributed linearly on the receiving rod 3 .

[0046] In the initial state, the spring 6 is in a compressed state. When the folded state of the bottom of the fan needs to be released, the limit ring 4 is manually controlled to rotate, so that the third ball 501 is subjected to the tilting force generated by the lock hole 301. At this time, the third ball 501 drives the plug-in column 5 to move toward the plug-in groove 401, further compressing the spring 6 until the third ball 501 is completely disengaged from the lock hole 301, thereby releasing the locking work of the limit ring 4 on the receiving rod 3, so that the receiving rod 3 can move freely relative to the receiving sleeve 2.

[0047] After the above-mentioned receiving rod 3 moves to the point where the supporting leg can contact the ground, the limit ring 4 can be controlled to reset so that the third ball 501 is again locked in the lock hole 301. Subsequently, when the support height of the fan needs to be adjusted, the limit ring 4 can be rotated multiple times so that the receiving rod 3 can move upward relative to the receiving sleeve 2, and the movement between the receiving rod 3 and the receiving sleeve 2 can be locked at any time.

[0048] A method for folding a base of a high-power fan structure, using any one of the above-mentioned high-power fan structures with a foldable base, comprises the following steps: Step 1: Before using the fan, manually release the folded state of the receiving sleeve 2 and the receiving rod 3. First, control the limit ring 4 to rotate relative to the receiving rod 3 to release the locking work of the receiving rod 3; Step 2: driving the receiving rod 3 to move relative to the receiving sleeve 2, and controlling the first adjusting member to work while the receiving rod 3 moves, so as to squeeze the multiple supporting legs and simultaneously rotate relative to the supporting base 1; Step 3: After the support legs rotate to contact the ground, when the support height of the fan needs to be adjusted, the receiving rod 3 is driven to move again to control the second adjustment member to work, so as to change the support radius of the support legs.
