Description

Technical Field

[0001] The present application relates to the field of wiring technology, and in particular to a folding wiring structure and a circulation fan. Background Art

[0002] Many circulating fans in related technologies lack a folding and folding function, making them inconvenient to store in winter and taking up space. While some circulating fans do have a folding and folding function, the wiring in their folding mechanism is susceptible to bending and long-distance displacement. Frequent folding can easily cause the wiring inside the fan to break, resulting in a loss of functionality and causing major quality issues. Utility Model Content

[0003] Based on this, it is necessary to provide a folding wiring structure and a circulation fan to address the problem that wiring breakage is prone to occur at the folding mechanism of the circulation fan.

[0004] To achieve the above objectives, the technical solutions adopted in this application are as follows:

[0005] In a first aspect, an embodiment of the present application provides a folded wiring structure, comprising:

[0006] A first connecting member is provided with a first wiring cavity, and a wiring groove and a first wire clamping groove are provided in the first wiring cavity;

[0007] a second connecting member, which is rotatably connected to the first connecting member and is provided with a second wiring cavity; a wiring hole is provided on one side of the second connecting member, and the wiring hole is used to connect the second wiring cavity and the first wiring cavity; and

[0008] The wiring is wound around the rotating connection between the first connecting member and the second connecting member and passes through the wiring groove, the first wire clamping groove and the wiring hole in sequence, and one end of the wiring is fixed in the first wiring cavity through the first wire clamping groove, and the other end is passed through the second wiring cavity through the wiring hole.

[0009] Through the above design, the wiring is arranged inside the first connecting member and the second connecting member and can rotate with the second connecting member, but the two ends of the wiring are respectively confined in the first connecting member and the second connecting member, reducing the risk of the wiring breaking due to the pulling generated during the rotation.

[0010] In one embodiment of the first aspect, the first connecting member includes a first connecting portion and an upper cover, wherein the upper cover covers the first connecting portion and defines the first wiring cavity with the first connecting portion;

[0011] The first wire-clamping slot is provided at the first connecting portion, and the upper cover is provided with a wire-blocking rib, which is engaged with the first wire-clamping slot.

[0012] Through the above design, the wire retaining ribs and the wall surface of the first wire clamping groove define an on-site rectangular notch to tightly restrict the side surfaces of the wiring in four directions and limit the stretching of the wiring end.

[0013] In one embodiment of the first aspect, a second wire clamping groove is defined in the second wire routing cavity, and one end of the wiring located in the second wire routing cavity is clamped in the second wire clamping groove.

[0014] With the above design, the two ends of the wiring are respectively limited by the first and second wire clamping grooves, so that the wiring cannot rotate along its own axis, and the problem of the wiring elasticity being reduced due to its own rotation and being easily broken by external force will not occur.

[0015] In one embodiment of the first aspect, the second connecting member includes a second connecting portion and a cover plate, the cover plate covers the second connecting portion and defines the second wiring cavity with the second connecting portion to cooperate with the second wire clamping groove to confine the end of the wiring away from the first wiring cavity within the second wiring cavity.

[0016] Through the above design, the wiring is confined to the second wiring cavity, the pulling movement of the wiring is reduced, and the wiring is shielded to improve the overall appearance.

[0017] In one of the embodiments of the first aspect, the second connecting member includes a first end face, an arcuate face, and a second end face arranged on the side of the wiring hole, the first end face, the arcuate face, and the second end face are distributed in sequence on three adjacent sides of the wiring hole, and the first end face and the second end face are used to limit the movement angle of the wiring.

[0018] With the above design, when the second connector is in a folded or unfolded state, the wiring contacts the first end face and the second end face respectively, thereby limiting the movement angle of the wiring and reducing the tensile damage of the wiring.

[0019] In one embodiment of the first aspect, the arcuate surface is provided with a transition fillet, and during the movement of the wiring, the transition fillet abuts against the wiring.

[0020] The above design reduces the frictional resistance between the wiring and the curved surface, and avoids wear caused by friction between the wiring and sharp edges.

[0021] In one embodiment of the first aspect, the first end surface and the second end surface form a preset angle, and the angle range of the preset angle is: 120° to 240°.

[0022] Through the above design, the curvature of the arc-shaped surface is limited, so as to limit the bending angle and displacement of the wiring according to the flipping angle of the second connection.

[0023] In one embodiment of the first aspect, a width of the wiring groove is greater than or equal to 15 mm.

[0024] Through the above design, the wiring can be completely placed in the wiring trough, completing the wiring layout.

[0026] Through the above design, the folding, storage or unfolding operation of the head assembly can be achieved.

[0027] In one embodiment of the second aspect, the circulation fan further includes a locking assembly, the locking assembly including a pressing member, the first connecting member defining a sliding groove and a limiting groove that are interconnected, the pressing member being mounted at a rotational connection between the second connecting member and the first connecting member and being capable of rotating along with the second connecting member, and the pressing member being telescopically disposed through the limiting groove and having an abutting portion;

[0028] When the abutting portion follows the pressing member to move to the sliding groove, the abutting portion can rotate in the sliding groove, and the pressing member follows the second connecting member to rotate;

[0029] When the abutting portion follows the pressing member to move to the limiting groove, the limiting groove and the abutting portion are engaged in a rotation-stopping manner, and the pressing member limits the rotation of the second connecting member.

[0030] Through the above design, the connection between the head assembly and the fuselage assembly is kept stable in the unfolded state without the need to manually turn the switch to lock it.

[0031] Compared with the related art, the beneficial effect of the present application is as follows: the present application provides a foldable wiring structure and a circulation fan for internal wiring of foldable electrical appliances. The foldable wiring structure includes a first connector, a second connector and wiring. The first connector is provided with a first wiring cavity, and a wiring groove and a first wire clamping groove are provided in the first wiring cavity. The second connector is provided with a second wiring cavity and is rotatably connected to the first connector, and one side of the second connector is provided with a wiring hole connected to the second wiring cavity.

[0061] See Figure 1 and Figure 3 As shown, the embodiment of the present application provides a foldable wiring structure 100 that can be used for internal wiring of rotating parts of various electrical appliances to reduce the risk of wiring 130 breakage caused by folding. It should be noted that for ease of understanding, this application uses a circulating fan 1000 as an example application scenario for the foldable wiring structure 100, but the foldable wiring structure 100 is not limited to application on circulating fans 1000.

[0062] Continue reading Figure 2 and Figure 4 As shown, specifically, the folding wiring structure 100 includes a first connector 110, a second connector 120 and a wiring 130. The first connector 110 and the second connector 120 are rotatably connected to achieve the folding, storage or unfolding operation of the first connector 110 and the second connector 120. The wiring 130 is wound around the rotatable connection between the first connector 110 and the second connector 120, and is arranged inside the first connector 110 and the second connector 120. It can rotate with the second connector 120, but the two ends of the wiring 130 are respectively confined within the first connector 110 and the second connector 120, reducing the risk of the wiring 130 being pulled during the rotation process and causing the wiring 130 to break.

[0063] Furthermore, the first connector 110 is provided with a first wiring cavity 1111, within which a wiring groove 1112 and a first wire retaining groove 1113 are defined. The second connector 120 is provided with a second wiring cavity 1211, and a wiring hole 1212 is provided on one side thereof, communicating with the second wiring cavity 1211. This allows the wiring hole 1212 to connect the second wiring cavity 1211 to the first wiring cavity 1111. In this manner, the wiring 130 is sequentially routed through the wiring groove 1112, the first wire retaining groove 1113, and the wiring hole 1212, thereby enabling the wiring 130 to be routed within the first connector 110 and the second connector 120.

[0064] At the same time, one end of the wiring 130 is fixed in the first wiring cavity 1111 by the first wire clamping groove 1113, while the other end of the wiring 130 is passed through the second wiring cavity 1211 through the wiring hole 1212. During the rotation of the second connector 120 relative to the first connector 110, one end of the wiring 130 is fixed by the first wire clamping groove 1113, limiting the movement of the wiring 130 within a short distance, avoiding the risk of long-distance wiring, which may lead to cluttered wiring and easy pulling and breaking. At the same time, the wiring 130 retains a certain bending length at the wiring hole 1212, allowing the wiring 130 to have a certain amount of movement during the rotation of the second connector 120, further preventing the wiring 130 from being pulled and broken.

[0065] Continue reading Figure 5 and Figure 6 As shown, the first connector 110 further includes a first connecting portion 111 and an upper cover 112. The upper cover 112 covers the first connecting portion 111 and defines a first wiring cavity 1111 with the first connecting portion 111. A first wire clamping groove 1113 is provided in the first connecting portion 111. The upper cover 112 is provided with a wire retaining rib 1121, which is engaged with the first wire clamping groove 1113.

[0066] For example, the upper cover 112 is detachably connected to the first connector 110, and the upper cover 112 is provided with a clamping block, and the first connector 110 is correspondingly provided with a connecting groove to engage with the upper cover 112. In other embodiments, the upper cover 112 and the first connector 110 can also be fastened with screws, which is not specifically limited here.

[0067] Specifically, the first wire-holding groove 1113 is a U-shaped groove structure with an opening on the upper side. When the upper cover 112 is installed on the first connecting member 110, the wire-holding rib 1121 is inserted into the open side of the first wire-holding groove 1113. The wire-holding rib 1121 and the wall of the first wire-holding groove 1113 define an on-site rectangular groove to tightly restrict the sides of the wiring 130 in four directions, thereby limiting the stretching of the end of the wiring 130.

[0068] Continue reading Figure 7 and Figure 8 As shown, in some embodiments, a second wire clamping groove 1213 is defined in the second wire routing cavity 1211 , and one end of the wiring 130 located in the second wire routing cavity 1211 is clamped in the second wire clamping groove 1213 .

[0069] Specifically, the second cable retaining slot 1213 is provided on the same side as the cable routing hole 1212, and multiple second cable retaining slots 1213 may be provided, such as two, three, or four, depending on actual needs. Thus, one end of the wiring 130 is secured within the first routing cavity 1111 by the first cable retaining slot 1113, while the other end enters the second routing cavity 1211 through the routing hole 1212 and is restrained by the second cable retaining slot 1213, reducing lateral movement of the wiring 130. Furthermore, the provision of multiple second cable retaining slots 1213 allows the wiring 130 to be routed along the extension direction of the second connector 120, integrating the wiring 130 within the first and second connectors 110, 120, and enabling it to rotate with the second connector 120 without being damaged by pulling during movement. The two ends of the wiring 130 are respectively limited by the first wire clamping groove 1113 and the second wire clamping groove 1213, so that the wiring 130 cannot rotate along its own axis, and the problem of the wiring 130 being easily broken by external force due to reduced elasticity caused by its own rotation will not occur.

[0070] In some embodiments, the second connecting member 120 includes a second connecting portion 121 and a cover plate 122. The cover plate 122 covers the second connecting portion 121 and defines a second wiring cavity 1211 with the second connecting portion 121 to cooperate with the second wire clamping groove 1213 to confine the end of the wiring 130 away from the first wiring cavity 1111 within the second wiring cavity 1211.

[0071] For example, the cover plate 122 and the second connecting portion 121 can each be provided with a latch and a connecting groove to facilitate assembly therebetween. In other embodiments, the cover plate 122 and the second connecting portion 121 can also be fastened with screws, which are not specifically limited herein. Thus, through the cooperation between the cover plate 122 and the second connecting portion 121, the wiring 130 is confined within the second wiring cavity 1211, reducing the pulling movement of the wiring 130 and shielding the wiring 130, thereby improving the overall appearance.

[0072] Furthermore, the second connecting member 120 includes a first end face 1215, an arcuate surface 1216 and a second end face 1217 arranged on the side of the wiring hole 1212. The first end face 1215, the arcuate surface 1216 and the second end face 1217 are distributed in sequence on three adjacent sides of the wiring hole 1212. The first end face 1215 and the second end face 1217 are used to limit the movement angle of the wiring 130 so that the wiring 130 will not produce a large displacement, thereby reducing the risk of the wiring 130 being pulled and broken.

[0073] Specifically, because the ends of the wiring 130 are restricted, a certain amount of movement is reserved for the wiring 130 at the wiring hole 1212 to allow the wiring 130 to follow the turning and bending of the second connector 120. When the second connector 120 is folded or unfolded, the wiring 130 abuts against the first end surface 1215 and the second end surface 1217, respectively, thereby limiting the movement angle of the wiring 130 and reducing the strain on the wiring 130.

[0074] Furthermore, the arcuate surface 1216 is provided with a transition fillet, and during the movement of the wiring 130, the transition fillet abuts against the wiring 130. It is understandable that during the rotational movement of the second connecting member 120, the wiring 130 inevitably contacts the arcuate surface 1216 of the second connecting member 120. Therefore, the provision of the transition fillet reduces the frictional resistance between the wiring 130 and the arcuate surface 1216, thereby preventing wear of the wiring 130 caused by friction with sharp edges.

[0075] In some embodiments, the first end face 1215 and the second end face 1217 form a preset angle, and the preset angle ranges from 120° to 240°.

[0076] For example, the first end surface 1215 and the second end surface 1217 can be used to limit the curvature of the curved surface 1216, thereby limiting the bending angle and displacement of the wiring 130 according to the rotation angle of the second connection. The preset angle can be 120°, 150°, 180°, 210°, 240°, etc., and can be selected according to actual needs to ensure that the wiring 130 moves in accordance with the rotation of the second connector 120.

[0077] In some embodiments, the width of the wiring groove 1112 is greater than or equal to 15 mm.

[0078] For example, in conventional household appliances, the diameter of the wiring 130 is often less than 15 mm, so that the width of the wiring trough 1112 is set so that the wiring 130 can be completely placed in the wiring trough 1112, completing the wiring arrangement of the wiring 130. Preferably, the width of the wiring trough 1112 can be 0.1 mm to 0.2 mm larger than the diameter of the wiring 130. This can meet the requirements for placement of the wiring 130 while limiting the range of movement of the wiring 130, thereby preventing the wiring 130 from causing large displacement during the rotation of the second connector 120, which could cause the risk of being pulled and broken.

[0079] An embodiment of the present application also provides a circulation fan 1000, including a body assembly 200, a head assembly 300 and a folding wiring structure 100 in any of the above embodiments, the body assembly 200 is fixedly connected to the first connecting member 110, and the head assembly 300 is rotatably connected to the second connecting member 120.

[0080] Specifically, the circulation fan 1000 is supported by the body assembly 200 and, when in operation, stands upright on the ground or a tabletop. The head assembly 300 is rotatably connected to the second connector 120, allowing it to rotate relative to the second connector 120 to adjust the operating angle. The first connector 110 is fixed to the body assembly 200, allowing the head assembly 300 and the second connector 120 to rotate relative to the body, allowing the head assembly 300 to be folded or unfolded.

[0081] This embodiment has the folded wiring structure 100 in any of the above embodiments, and therefore has all the beneficial effects of the folded wiring structure 100 in any of the above embodiments, which will not be described in detail here.

[0082] Furthermore, the head assembly 300 may include blades and a drive motor. When powered on, the drive motor drives the blades to rotate to dissipate heat. The second connecting member 120 has a Y-shaped structure, with its bottom end rotatably connected to the first connecting member 110. The head assembly 300 is installed between the upper ends of the second connecting member 120 and is rotatably connected to the upper ends of the second connecting member 120, thereby achieving stable installation of the head assembly 300. During operation, the head assembly 300 can rotate relative to the second connecting member 120 to adjust the operating angle.

[0083] Continue reading Figure 9 and Figure 10 As shown, in some embodiments, the circulation fan 1000 also includes a locking assembly 500, the locking assembly 500 includes a pressing member 510, the first connecting member 110 is provided with a sliding groove 1115 and a limiting groove 1116 that are interconnected, the pressing member 510 is installed at the rotating connection between the second connecting member 120 and the first connecting member 110, and can rotate with the second connecting member 120, and the pressing member 510 can be telescopically passed through the limiting groove 1116 and is provided with an abutment portion 511.

[0084] When the abutting portion 511 follows the pressing member 510 to move to the sliding groove 1115, the abutting portion 511 can rotate within the sliding groove 1115, and the pressing member 510 rotates along with the second connecting member 120. When the abutting portion 511 follows the pressing member 510 to move to the limiting groove 1116, the limiting groove 1116 and the abutting portion 511 are locked in rotation, and the pressing member 510 restricts the rotation of the second connecting member 120.

[0085] Specifically, the side of the pressing member 510 away from the second connecting member 120 is a solid pressing surface, so that when an external force acts on the pressing surface, the pressing member 510 can move along the axial direction. An abutment portion 511 is provided at the end of the pressing member 510 away from the pressing surface. The second connecting member 120 is also provided with a through hole. The cavity structure of the through hole is adapted to the abutment portion 511. Therefore, during the assembly process of the pressing member 510, the abutment portion 511 passes through the hole and enters the limiting groove 1116. Then, during the pressing process of the pressing member 510, it enters the slide groove 1115 through the limiting groove 1116.

[0086] For example, when the second connector 120 is unfolded relative to the first connector 110, the abutment 511 is located in the limiting groove 1116. The wall surface of the limiting groove 1116 contacts the abutment 511, so that the pressing member 510 cannot rotate arbitrarily, thereby limiting the rotation of the second connector 120 and maintaining the stability of the second connector 120 in the unfolded state without the need for an additional manual locking switch, reducing manpower and facilitating operation. When the second connector 120 needs to be folded, it is only necessary to press the pressing surface of the pressing member 510 to move the pressing member 510 toward the inside of the second connector 120. The abutment 511 disengages from the wall surface of the limiting groove 1116 and enters the interior of the chute 1115. The abutment 511 can move with the second connector 120 in the chute 1115, thereby rotating the second connector 120 so that the second connector 120 and the first connector 110 are folded together for easy storage.

[0087] Furthermore, the abutting portion 511 includes an arcuate surface 1216 and two first resisting surfaces distributed at both ends of the arcuate surface 1216. The limiting groove 1116 is provided with two second resisting surfaces opposite to each other. When the abutting portion 511 is located in the limiting groove 1116, each second resisting surface abuts against the corresponding first resisting surface.

[0088] Specifically, the first and second resisting surfaces are both planar structures, so that the abutting portion 511 and the limiting groove 1116 are not regular circular structures. When the abutting portion 511 is located in the limiting groove 1116, the first and second resisting surfaces interfere with each other, and the pressing member 510 cannot rotate within the limiting groove 1116.

[0089] Furthermore, the pressing member 510 includes a main body 512. An abutting portion 511 is disposed at one end of the main body 512 proximal to the first connector 110 and protrudes from the circumferential surface of the main body 512 to form a flange. When the abutting portion 511 is located in the chute 1115 and not aligned with the limiting groove 1116, the flange abuts against a side wall of the chute 1115, thereby preventing the abutting portion 511 from axially returning to the limiting groove 1116.

[0090] It is understandable that due to the setting of the first resisting surface, the distance between the axis of the pressing member 510 and the first resisting surface is smaller than the distance between the axis and the arc surface. In order to allow the abutting portion 511 to rotate within the slide 1115, the slide 1115 needs to be set with the distance between the axis of the pressing member 510 and the arc surface as the radius. Therefore, the limiting groove 1116 is narrowed relative to the slide 1115. When the abutting portion 511 is not completely aligned with the limiting groove 1116, the abutting portion 511 is blocked by the connecting wall of the slide 1115 and the limiting groove 1116 and cannot return to the limiting groove 1116, thereby preventing the abutting portion 511 from returning to the limiting groove 1116 when the second connecting member 120 is folded, and the pressing member 510 needs to be pressed again to unfold the second connecting member 120.

[0091] In some embodiments, the locking assembly 500 further includes an elastic member 520 , and two ends of the elastic member 520 are respectively connected to the pressing member 510 and the second connecting member 120 .

[0092] Specifically, the elastic member 520 can be a helical compression spring, with its two ends connected to the pressing member 510 and the second connecting member 120, respectively, to achieve a press-to-reset position for the pressing member 510. In a normal state, the elastic member 520 is in a stretched state, pressing the pressing member 510 outward, positioning the abutment portion 511 within the limiting groove 1116. During the rotation of the second connecting member 120, pressing the pressing member 510 causes the elastic member 520 to contract, causing the abutment portion 511 to enter the sliding groove 1115, and the pressing member 510 to rotate with the second connecting member 120.

[0093] For example, when the second connecting member 120 is in the folded state, the elastic member 520 presses the pressing member 510 outward due to its elastic potential energy, causing the abutting portion 511 to abut against the wall of the sliding groove 1115 and prevent it from returning to the limiting groove 1116. When the second connecting member 120 is rotated to the unfolded state, the abutting portion 511 is fully aligned with the limiting groove 1116, and the elastic member 520 presses the pressing member 510 outward, causing the abutting portion 511 to enter the limiting groove 1116 and be unable to rotate due to the restriction of the limiting groove 1116 wall.

[0094] Continue reading Figure 11 As shown, in some embodiments, the second connecting member 120 has a U-shaped notch and two oppositely disposed rotational shafts 1214. The first connecting member 110 is correspondingly provided with a cavity that rotatably cooperates with the rotational shafts 1214, and the second connecting member 120 is rotatably connected to the first connecting member 110 via the rotational shafts 1214.

[0095] Furthermore, the second connecting member 120 is further provided with a plurality of positioning blocks, each of which is disposed at the end of the rotating shaft 1214 away from the first connecting member 110 and is distributed circumferentially about the axis of the rotating shaft 1214. A cavity is defined within the pressing member 510, allowing the pressing member 510 to be inserted into the outer side of the positioning blocks, allowing the pressing member 510 to be mounted on the second connecting member 120 and to telescopically slide relative to the positioning blocks.

[0096] Preferably, a plurality of positioning grooves can be provided inside the pressing member 510 so that when the pressing member 510 is plugged into the positioning block, the positioning block is inserted into the positioning groove, thereby achieving rapid assembly of the pressing member 510 and the second connecting member 120. At the same time, the cooperation between the positioning grooves and the positioning block can limit the installation angle of the pressing member 510, thereby achieving precise positioning and assembly of the pressing member 510.

[0097] Furthermore, a buckle is provided on one side where the second connecting member 120 connects to the pressing member 510, and a corresponding slot is provided on the pressing member 510. When the pressing member 510 is mounted on the second connecting member 120, the buckle and the slot engage. The engagement of the buckle and the slot further enhances the assembly stability of the pressing portion and the second connecting member 120 and facilitates the installation and positioning of the pressing member 510.

[0098] In some embodiments, the circulation fan 1000 further includes a connecting assembly 600, which includes a plug-in assembly 610 and a locking member. The plug-in assembly 610 sequentially passes through the first connecting member 110 and the second connecting member 120, so that the second connecting member 120 rotates relative to the first connecting member 110 about the plug-in assembly 610. The locking member is provided at one end of the plug-in assembly 610 to limit the plug-in assembly 610 and prevent it from falling off during rotation.

[0099] In one embodiment, the insertion member 610 can be a bolt, and the locking member can be a nut. The first connecting member 110 and the second connecting member 120 are both provided with corresponding connection holes. After the bolt passes through the first connecting member 110 and the second connecting member 120, it is locked and limited by the nut, so that the second connecting member 120 can rotate relative to the first connecting member 110 and will not fall off the raised frame during the movement.

[0100] In another embodiment, the insertion member 610 may also be a pin with limited holes at both ends, and the locking member may be a cotter pin, so that the cotter pin passes through the limit block of the pin to limit the pin, so that the second connecting member 120 is installed on the first connecting member 110. Of course, in other embodiments, the second connecting member 120 and the first connecting member 110 may also be connected in a manner that satisfies the rotational connection between the second connecting member 120 and the first connecting member 110, and no specific limitation is made here.

[0101] In some embodiments, the circulation fan 1000 further includes a plurality of friction plates 140 , the first connecting member 110 is provided with a plurality of mounting slots 1114 , each friction plate 140 is respectively installed in a corresponding mounting slot 1114 , and the insert 610 is inserted through each friction plate 140 in sequence.

[0102] Exemplarily, two friction plates 140 and two mounting slots 1114 are provided, and the two friction plates 140 are symmetrically arranged on either side of the second connecting member 120. During installation, the insert 610 sequentially passes through one friction plate 140, the second connecting member 120, and the other friction plate 140 before being secured to the locking member. As the second connecting member 120 rotates, the friction plates 140 provide friction to the second connecting member 120, offsetting some of the potential energy of the second connecting member 120 during rotation, reducing the rotational speed of the second connecting member 120, and minimizing component wear.

[0103] Continue reading Figure 12 、 Figure 13 and Figure 14 As shown, in some embodiments, the circulation fan 1000 further includes a chassis 400. The fuselage assembly 200 includes a plurality of telescopic rods 210, and each telescopic rod 210 is slidably connected in sequence. It can be understood that each telescopic rod 210 is a hollow tube structure with different outer diameters to achieve the mutual connection of each telescopic rod 210. The specific principle is not described in detail here. The operating height adjustment of the circulation fan 1000 is achieved by adjusting the telescopic rod 210. At the same time, during the folding and storage process, the storage space of the circulation fan 1000 can be further reduced by contracting the telescopic rod 210.

[0104] In addition, the bottom end of the body assembly 200 is detachably connected to the chassis 400. During assembly of the circulating fan 1000, the body assembly 200 and the chassis 400 are locked together, thereby connecting to the bottom surface through the chassis 400, ensuring the stable support of the circulating fan 1000 when in a standing position. When folding and storing the circulating fan 1000, the body assembly 200 and the chassis 400 can be separated, further reducing the space occupied by the circulating fan 1000.

[0105] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application.
