Description

Technical Field

[0001] The present application relates to the technical field of fan folding, and in particular to an adjustable fan. Background Art

[0002] Electric fans have gradually become an indispensable part of people's lives, especially in summer. However, in the related art, electric fans have the problems of being large in size, occupying a lot of space, having a fixed structure and relatively simple functions, and being inconvenient to store, which cannot meet the storage needs of users. Utility Model Content

[0003] Based on this, it is necessary to provide an adjustable fan to address the problem of inconvenient fan storage.

[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 an adjustable fan, comprising:

[0006] A head assembly, comprising a bracket and a fan head rotatably mounted on the bracket;

[0007] The fuselage assembly includes a first tube, a second tube, and a rotating frame. The first tube and the second tube are telescopically connected. The rotating frame is installed at an end of the first tube facing away from the second tube and is rotatably connected to an end of the bracket away from the fan head.

[0008] The head assembly can be controlled to flip, unfold, or fold on the fuselage assembly. The fuselage assembly has two states: extended and contracted. The overall length of the fuselage assembly in any state is greater than the overall length of the head assembly.

[0009] Through the above design, the overall length of the fuselage assembly in the extended or contracted state is greater than the overall length of the head assembly, so that the head assembly can be fitted on the fuselage assembly, reserving sufficient folding space for the head assembly to ensure the supporting function of the fuselage assembly after folding.

[0010] In one embodiment, the distance between the connecting axis of the bracket and the fan head and the connecting axis of the bracket and the rotating frame is D1, and D1 is 150mm-400mm.

[0011] Through the above design, it is ensured that the length of the head assembly after folding is roughly the same as the length of the body assembly after contraction, ensuring the minimum size after folding.

[0012] In one embodiment, the fuselage assembly further comprises an upper cover provided on a side of the rotating frame facing away from the first tube, and an axis of the first tube and the side of the upper cover facing away from the rotating frame have an intersection point o;

[0013] When the head assembly is unfolded on the fuselage assembly, the distance between the end of the fan head close to the upper cover and the intersection o is D2, and D2 is 10mm-120mm.

[0014] The above design ensures that the fan head has enough space to avoid shaking its head.

[0015] In one embodiment, the body assembly further includes a rotating sleeve and a support shaft, the rotating sleeve is arranged on the end of the first tube away from the second tube, the support shaft is installed in the rotating sleeve, and the rotating frame is clamped on the end of the support shaft away from the rotating sleeve and is rotatably connected to the head assembly.

[0016] The above design facilitates the rotation and folding of the head assembly, and enables the center of gravity of the entire machine to fall on the axis of the body assembly, thereby ensuring the operational stability of the entire machine.

[0017] In one embodiment, the distance between the intersection point o and the end of the rotating sleeve facing away from the upper cover is D3, and D3 is greater than 50 mm.

[0018] The above design ensures that there is enough space for setting up the shaking head mechanism.

[0019] In one embodiment, a support column is provided in the middle of the support shaft, and two buckles are provided on the outer side of the support shaft;

[0020] A connecting column is provided in the middle of the rotating frame, and a clamping slot is provided on the peripheral side of the connecting column, so that after the connecting column is sleeved on the outer side of the supporting column, the two buckles are clamped in the clamping slot.

[0021] With the above design, after the connecting post extends into the interior of the support shaft, the buckle with a certain elasticity is clamped in the clamping groove of the connecting post under the action of elastic force, further enhancing the installation stability of the rotating frame.

[0022] In one embodiment, the distance between the axis of the first pipe and the connection axis of the rotating frame and the bracket is D4, and D4 is 30 mm-150 mm.

[0023] The above design ensures that the overall thickness of the fan after folding is optimal.

[0024] In one embodiment, a distance between an end of the first pipe member close to the second pipe member and the intersection o is D5, and D5 is 200 mm-600 mm.

[0025] The above design ensures that the second pipe can be completely retracted into the first pipe, thereby ensuring the retractable adjustment range of the entire device.

[0026] In one embodiment, the adjustable fan further includes a telescopic adjustment assembly, which is arranged at the connection between the first pipe and the second pipe, the telescopic adjustment assembly including a connecting piece, a locking piece and a nut piece, the connecting piece is mounted on an end of the second pipe close to the first pipe and slidably penetrates the first pipe, the locking piece has a tightening end, the tightening end penetrates an end of the first pipe close to the second pipe and can be tightened to or disengaged from the connecting piece under the action of an external force, the nut piece is mounted on an end of the first pipe close to the second pipe, the locking piece is threadedly engaged with the nut piece, and the locking piece is controlled to rotate relative to the nut piece to move closer to or away from the connecting piece;

[0027] When the abutting end abuts against the connecting piece, the first pipe member and the second pipe member remain relatively fixed; when the abutting end is separated from the connecting piece, the first pipe member can slide relative to the second pipe member.

[0028] Through the above design, the locking member is rotated and moves relative to the nut plate, thereby achieving the contact and separation between the abutting end of the locking member and the connecting member, thereby controlling the relative movement between the first tube and the second tube and adjusting the height of the fuselage assembly.

[0029] In one embodiment, the telescopic adjustment assembly also includes a sleeve, which is fixed to the end of the first tube close to the second tube. The connecting member slides through the sleeve and is provided with a flange edge at the end away from the second tube. When the first tube reaches the maximum stretching position, the flange edge is pressed against the end of the sleeve.

[0030] With the above design, under the restriction of the flange edge, the second pipe cannot be separated from the first pipe, which facilitates the telescopic adjustment of the second pipe.

[0031] In one embodiment, a notch is formed on a side of the sleeve close to the locking member, so that the connecting member can be exposed in the notch.

[0032] With the above design, the abutting end of the locking member can pass through the notch and abut against the surface of the connecting member to limit the movement of the second pipe member.

[0033] In one embodiment, the telescopic adjustment assembly further includes a pressure block having a plurality of retaining ribs, and the sleeve is provided with a plurality of abutment surfaces correspondingly along the circumferential side of the notch, and each retaining rib is respectively fitted to a correspondingly provided abutment surface.

[0034] With the above design, when the locking member abuts, the pressing block can abut against the connecting member, restricting the movement of the second pipe member. When the locking member is released, the pressing block can be reset under the action of elastic force, separating from the connecting member, and the second pipe member can resume movement.

[0035] In one embodiment, the adjustable fan further comprises a chassis, and the second pipe is detachably connected to the chassis;

[0036] The fan head has a front mesh surface, and the front mesh surface can be assembled and matched with the chassis.

[0037] Through the above design, the front mesh surface of the fan head is placed in close contact with the chassis, further reducing the storage space of the fan.

[0038] Compared to related technologies, the present application provides an adjustable fan that facilitates folding and storage. The adjustable fan includes a head assembly and a body assembly. The head assembly includes a bracket and a fan head rotatably mounted on the bracket. The body assembly includes a first tube, a second tube, and a rotating frame. The first and second tubes are telescopically coupled to adjust the overall height of the body assembly.

[0039] The rotating frame is mounted on the first pipe and rotatably connected to the bracket. This allows the adjustable fan to be adjusted in both operating and storage heights through the body assembly. During storage, the head assembly can be folded onto the body assembly, reducing space usage. Furthermore, the overall length of the body assembly, whether extended or retracted, is greater than the overall length of the head assembly, allowing the head assembly to fit snugly onto the body assembly, ensuring the support function of the folded body assembly.

[0070] In this application, unless otherwise expressly specified or limited, if a first feature is described as being "above" or "below" a second feature, or similar descriptions, this may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Furthermore, when a first feature is described as being "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. When a first feature is described as being "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0071] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element.

If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only embodiment.

[0072] See Figure 1 and Figure 2 As shown, an embodiment of the present application provides an adjustable fan that can be used for folding and storing the fan, reducing the occupied space and meeting the user's needs in various application scenarios.

[0073] Specifically, the adjustable fan includes a head assembly 110 and a body assembly 120. The head assembly 110 and the body assembly 120 are rotatably connected, allowing the head assembly 110 to rotate relative to the body assembly 120 to adjust the operating angle of the head assembly 110. Furthermore, when the fan is stored, the head assembly 110 can be rotated to fold the head assembly 110 and the body assembly 120, thereby reducing the space occupied by the fan.

[0074] Furthermore, the head assembly 110 includes a bracket 112 and a fan head 111 rotatably mounted on the bracket 112. The fuselage assembly 120 includes a first tube 121, a second tube 122, and a rotating frame 125. The first tube 121 and the second tube 122 are telescopically engaged with each other. The rotating frame 125 is mounted on an end of the first tube 121 facing away from the second tube 122 and is rotatably connected to an end of the bracket 112 away from the fan head 111.

[0075] Among them, the head assembly 110 can be controlled to flip and unfold or fold on the fuselage assembly 120. The fuselage assembly 120 has two states: extension and contraction, and the overall length of the fuselage assembly 120 in any state is greater than the overall length of the head assembly 110, so that the head assembly 110 can fit on the fuselage assembly 120 after folding, reserving sufficient folding space for the head assembly 110 to ensure the supporting function of the fuselage assembly 120 after folding.

[0076] Furthermore, a distance between a connection axis between the bracket 112 and the fan head 111 and a connection axis between the bracket 112 and the rotating frame 125 is D1, and D1 is 150 mm to 400 mm.

[0077] Preferably, D1 can be 150mm, 162mm, 189mm, 193mm, 205mm, 216mm, 223mm, 231mm, 262mm, 292mm, 305mm, 362mm, 400mm, etc., and can be specifically designed according to actual needs to ensure that the length of the head assembly 110 after folding is roughly the same as the length of the body assembly 120 after contraction, ensuring the minimum size after folding.

[0078] Furthermore, the fuselage assembly 120 also includes an upper cover 126 that covers the side of the rotating frame 125 facing away from the first tube 121. The axis of the first tube 121 and the side of the upper cover 126 facing away from the rotating frame 125 intersect at a point o. When the head assembly 110 is deployed within the fuselage assembly 120, the distance D2 between the end of the fan head 111 closest to the upper cover 126 and the intersection o is 10 mm to 120 mm.

[0079] Preferably, D2 can be 10mm, 12mm, 15mm, 20.3mm, 52.4mm, 60.08mm, 63.22mm, 65.07mm, 75.23mm, 82.1mm, 96.5mm, 100.3mm, 110.3mm, 120mm, etc., and can be designed according to actual needs to ensure that the fan head 111111 has enough space to avoid shaking the head.

[0080] Furthermore, the body assembly 120 also includes a rotating sleeve 123 and a support shaft 124. The rotating sleeve 123 is mounted on the end of the first tube 121 away from the second tube 122. The support shaft 124 is installed in the rotating sleeve 123. The rotating frame 125 is clamped to the end of the support shaft 124 away from the rotating sleeve 123 and is rotatably connected to the head assembly 110. The end of the rotating frame 125 connected to the bracket 112 extends outward from the first tube 121, thereby facilitating the rotation and folding of the head assembly 110 and ensuring the center of gravity of the entire machine falls on the axis of the body assembly 120, ensuring the operational stability of the entire machine.

[0081] Furthermore, the distance between the intersection point o and the end of the rotating sleeve 123 facing away from the upper cover 126 is D3, and D3 is greater than 50 mm.

[0082] Preferably, D3 can be 51mm, 62mm, 75mm, 79.3mm, 82.5mm, 90.03mm, 95.76mm, 100.8mm, 121.1mm, etc., and can be designed according to actual needs to ensure that there is enough space for setting up the shaking mechanism.

[0083] Furthermore, the distance between the axis of the first pipe 121 and the connection axis of the rotating frame 125 and the bracket 112 is D4, and D4 is 30 mm-150 mm.

[0084] Preferably, D4 can be 30mm, 42mm, 45mm, 50.3mm, 72.5mm, 88.17mm, 100.03mm, 123.77mm, 131.08mm, 141.11mm, 150mm, etc., and can be designed according to actual needs to ensure that the overall thickness of the fan after folding is optimal.

[0085] Furthermore, a distance between an end of the first pipe 121 close to the second pipe 122 and the intersection o is D5, and D5 is 200 mm-600 mm.

[0086] Preferably, D5 can be 200mm, 230mm, 280mm, 300mm, 320mm, 354mm, 387.2mm, 413.59mm, 470.9mm, 491.3mm, 500.5mm, 523.7mm, 570.03mm, 600mm, etc., and can be specifically designed according to actual needs to ensure that the second pipe 122 can be completely retracted into the first pipe 121, thereby ensuring the retractable adjustment range of the entire machine.

[0087] Continue reading Figure 3 As shown, the adjustable fan further includes a telescopic adjustment assembly 130. The body assembly 120 includes a first tube 121 and a second tube 122 that fit together. The telescopic adjustment assembly 130 is installed at the connection between the first tube 121 and the second tube 122 to adjust the connection length of the first tube 121 and the second tube 122. When the telescopic adjustment assembly 130 locks the first tube 121 and the second tube 122, the first tube 121 and the second tube 122 remain relatively fixed, ensuring the connection strength during operation and providing stable support for the fan as a whole. When the telescopic adjustment assembly 130 does not lock the first tube 121 and the second tube 122, the second tube 122 can telescope and move within the first tube 121 to adjust the operating height of the fan. During storage, the second tube 122 can be completely inserted into the first tube 121, further reducing the occupied space.

[0088] Specifically, the telescopic adjustment assembly 130 includes a connector 131 and a locking member 132. The connector 131 is mounted on an end of the second tubular member 122 proximate to the first tubular member 121 and slides through the first tubular member 121. When the second tubular member 122 contracts, the connector 131 follows the second tubular member 122 and contracts within the first tubular member 121. The locking member 132 has a tightening end 1321, which is inserted through an end of the first tubular member 121 proximate to the second tubular member 122 and is capable of moving along its own axis relative to the first tubular member 121 to engage or disengage the connector 131 under the action of an external force. Thus, when the tightening end 1321 abuts the connector 131, the first tubular member 121 and the second tubular member 122 remain relatively fixed. When the tightening end 1321 separates from the connector 131, the first tubular member 121 can slide relative to the second tubular member 122.

[0089] Continue reading Figure 4 and Figure 5 As shown, for example, one end of the connector 131 is plugged into the end of the second tube 122 near the first tube 121, and corresponding screw holes are provided on the end of the connector 131 inserted into the second tube 122 and the end of the second tube 122 near the first tube 121. Thus, after the connector 131 is inserted into the second tube 122, the screw holes of the connector 131 and the second tube 122 are aligned and tightened by screws, thereby completing the assembly of the connector 131 and the second tube 122.

[0090] Continue reading Figure 6 and Figure 7 As shown, the locking member 132 is exemplarily a knob structure with a cap structure at one end and a threaded rod at the other end. A hole is provided at the end of the first tubular member 121 near the second tubular member 122, allowing the threaded rod to pass through the hole and into the interior of the first tubular member 121. The threaded rod is threadedly engaged with the first tubular member 121, allowing rotation of the cap to control the threaded rod's movement into or out of the first tubular member 121, thereby controlling the abutment end's engagement or separation with the connector 131 located within the first tubular member 121.

[0091] See also Figure 4 and Figure 8 As shown, in some embodiments, the telescopic adjustment assembly 130 further includes a sleeve 133, which is fixed to an end of the first tube 121 near the second tube 122. The connector 131 slides through the sleeve 133 and has a flange 1311 at one end away from the second tube 122. When the first tube 121 reaches the maximum extension position, the flange 1311 abuts against the end of the sleeve 133.

[0092] Specifically, after the connector 131 and the second tube 122 are assembled, the sleeve 133 is sleeved onto the outside of the connector 131. The flange 1311 prevents the sleeve 133 from being detached from one side of the connector 131. The sleeve 133 and the second tube 122 are then simultaneously inserted into the first tube 121. The sleeve 133 is aligned with the corresponding screw holes in the first tube 121, and the sleeve 133 and the first tube 121 are tightened with screws. This allows the second tube 122 and the connector 131 to be inserted into the first tube 121. The flange 1311 prevents the second tube 122 from being detached from the first tube 121, facilitating telescopic adjustment of the second tube 122.

[0093] Furthermore, a notch 1331 is formed on one side of the sleeve 133 close to the locking member 132 so that the connecting member 131 can be exposed to the notch 1331 , so that the abutting end of the locking member 132 can pass through the notch 1331 and press against the surface of the connecting member 131 to limit the movement of the second tube 122 .

[0094] Continue reading Figure 9 As shown, further, the telescopic adjustment assembly 130 also includes a pressure block 134, which has a plurality of retaining ribs 1341, and the sleeve 133 is provided with a plurality of abutment surfaces 1332 along the circumferential side of the notch 1331, and each retaining rib 1341 is respectively fitted to a corresponding abutment surface 1332.

[0095] Specifically, during assembly, the retaining ribs 1341 of the pressing block 134 engage the abutting surfaces 1332, allowing the pressing block 134 to be installed in the notch 1331 of the sleeve 133. Due to the provision of the retaining ribs 1341, the pressing block 134 has a certain degree of elasticity. Therefore, when the locking member 132 abuts against the pressing block 134, the pressing block 134 can abut against the connecting member 131, restricting the movement of the second tube 122. When the locking member 132 is released, the pressing block 134 can return to its original position under the action of the elastic force, separating from the connecting member 131, and the second tube 122 can resume movement.

[0096] Continue reading Figure 10 As shown, the telescopic adjustment assembly 130 further includes a fixing block 135. The fixing block 135 and the pressing block 134 are respectively provided with mutually cooperating clamping blocks and clamping grooves, so that the fixing block 135 is installed on the side of the pressing block 134 facing away from the shaft sleeve 133. In this way, the abutting end of the locking member 132 abuts against the fixing block 135 without directly contacting the pressing block 134, thereby reducing wear on the pressing block 134.

[0097] Continue reading Figure 11 As shown, further, the telescopic adjustment assembly 130 also includes a nut piece 136, which is installed on one end of the first pipe 121 close to the second pipe 122, and the locking member 132 is threadedly matched with the nut piece 136.

[0098] See also Figure 12 As shown, the bottom of the first pipe 121 is provided with a receiving groove 1211, and the nut plate 136 is installed in the receiving groove 1211. The locking member 132 passes through the tube wall of the first pipe 121 and the nut plate 136 in sequence and is threadedly connected to the nut plate 136. In this way, by rotating the locking member 132, the locking member 132 moves relative to the nut plate 136, thereby achieving the contact and separation between the abutting end of the locking member 132 and the fixing block 135.

[0099] In some embodiments, the head assembly 110 includes a bracket 112 rotatably connected to the body assembly 120 and a fan head 111 rotatably mounted on the bracket 112. The fan head 111 is the operating component of the fan, delivering wind to the user during operation. The bracket 112 allows the fan head 111 to rotate relative to the bracket 112 during operation, thereby adjusting the operating angle. Furthermore, when folded and stored, the fan head 111 can be folded to a 0° angle relative to the body assembly 120 via the bracket 112.

[0100] Continue reading Figure 13 and Figure 14 As shown, specifically, the fan head 111 includes a main housing 1111, a rotating shaft 1112, and a cover plate 1113. A rib 11111 is provided on the circumference of the main housing 1111. A gear ring 11121 is provided at one end of the rotating shaft 1112. The gear ring 11121 is in contact with the rib 11111. The cover plate 1113 is sleeved on the end of the rotating shaft 1112 away from the gear ring 11121. The end of the rotating shaft 1112 away from the main housing 1111 extends out of the cover body 1122 and is connected to the bracket 112. The cover plate 1113 and the rib 11111 are both provided with corresponding screw holes. After the screw holes of the cover plate 1113 and the rib 11111 are aligned, the cover plate 1113 and the rib 11111 are fastened by screws, so that the main housing 1111 and the cover plate 1113 can rotate relative to the rotating shaft 1112, thereby adjusting the operating angle of the fan head 1111.

[0101] Furthermore, the fan head 111 also includes an upper shell 1114 and a lower shell 1115 . The upper shell 1114 and the lower shell 1115 are respectively clamped on the upper and lower sides of the main shell 1111 through clamping columns to cover the sides of the main shell 1111 .

[0102] See also Figure 15 As shown, the bracket 112 includes a frame 1121 and a cover 1122. The cover 1122 and the frame 1121 can be provided with a snap-fit ​​block and a snap-fit ​​groove respectively to achieve assembly and cooperation between them. In other embodiments, the cover 1122 and the frame 1121 can also be fastened with screws, which is not specifically limited here.

[0103] For example, the bracket 112 has a Y-shaped structure, with its bottom end pivotally connected to the fuselage assembly 120. Mounting holes are provided at both ends of the bracket 112's top. Two rotational shafts 1112 are provided and located on opposite sides of the main housing 1111. The two rotational shafts 1112 are then secured to the two mounting holes using screws. Thus, the fan head 111 is mounted between the top ends of the bracket 112 and pivotally connected to the top ends of the bracket 112, ensuring stable mounting of the fan head 111. During operation, the fan head 111 can rotate relative to the bracket 112 to adjust the operating angle.

[0104] Continue reading Figure 16 As shown, in some embodiments, the fuselage assembly 120 further includes a rotating sleeve 123, a support shaft 124 and a rotating frame 125. The rotating sleeve 123 is sleeved on the end of the first tube 121 away from the second tube 122. The support shaft 124 is installed in the rotating sleeve 123. The rotating frame 125 is clamped on the end of the support shaft 124 away from the rotating sleeve 123 and is rotatably connected to the head assembly 110.

[0105] See also Figure 17 and Figure 18 As shown, specifically, the tops of the rotating sleeve 123 and the first tube 121 are respectively provided with positioning grooves and positioning ribs to clamp the rotating sleeve 123 inside the first tube 121. The rotating sleeve 123 and the first tube 121 are then aligned through the screw holes and screwed together using screws. The support shaft 124 is inserted into the rotating sleeve 123, and the screw column of the support shaft 124 is aligned with the screw hole of the rotating sleeve 123. The support shaft 124 and the rotating sleeve 123 are then fixed together using screws. Finally, the bottom of the rotating frame 125 is connected to the support shaft 124 and the rotating sleeve 123, and the top of the rotating frame 125 is rotatably connected to the bracket 112 to achieve the folding of the head assembly 110 and the fuselage assembly 120.

[0106] See also Figure 18 and Figure 19 As shown, further, a support column 1241 is provided in the middle of the support shaft 124, and two clips 1242 are provided on the outer side of the support shaft 124. A connecting column 1251 is provided in the middle of the rotating frame 125, and a slot 1252 is formed around the connecting column 1251. After the connecting column 1251 is sleeved on the outer side of the support column 1241, the two clips 1242 are snapped into the slot 1252.

[0107] Specifically, the rotating frame 125 is sleeved on the outside of the rotating sleeve 123, and the connecting post 1251 is sleeved on the outside of the support post 1241, thereby strengthening the connection between the rotating frame 125 and the first pipe 121. At the same time, after the connecting post 1251 extends into the interior of the support shaft 124, the elastic buckle 1242 is clamped to the slot 1252 of the connecting post 1251 under the action of elastic force, further strengthening the installation stability of the rotating frame 125.

[0108] See also Figure 20 and Figure 21 As shown, in some embodiments, the adjustable fan also includes a locking assembly 160, the locking assembly 160 includes a pressing member 161, the rotating frame 125 is provided with a sliding groove 1253 and a limiting groove 1254 that are interconnected, the pressing member 161 is installed at the rotating connection between the rotating frame 125 and the head assembly 110, and can rotate with the head assembly 110, and the pressing member 161 can be telescopically passed through the limiting groove 1254 and is provided with an abutment portion 1611.

[0109] Specifically, the side of the pressing member 161 away from the head assembly 110 is a solid pressing surface, so that when an external force acts on the pressing surface, the pressing member 161 can move along the axial direction. The abutment portion 1611 is provided at the end of the pressing member 161 away from the pressing surface. The head assembly 110 is also provided with a through hole, and the cavity structure of the through hole is adapted to the abutment portion 1611, so that the abutment portion 1611 enters the limiting groove 1254 through the hole during the assembly process of the pressing member 161, and then enters the slide groove 1253 through the limiting groove 1254 during the pressing process of the pressing member 161.

[0110] For example, when the head assembly 110 is unfolded relative to the body assembly 120, the abutment 1611 is located in the limiting groove 1254. The wall surface of the limiting groove 1254 contacts the abutment 1611, so that the pressing member 161 cannot rotate arbitrarily, thereby limiting the rotation of the head assembly 110 and maintaining the stability of the head assembly 110 in the unfolded state without the need for an additional manual locking switch, reducing manpower and facilitating operation. When the head assembly 110 needs to be folded, it is only necessary to press the pressing surface of the pressing member 161 to move the pressing member 161 toward the inside of the head assembly 110, and the abutment 1611 will break away from the wall surface of the limiting groove 1254 and enter the interior of the slide 1253. The abutment 1611 can move with the head assembly 110 in the slide 1253, and then the head assembly 110 can be rotated, so that the head assembly 110 and the body assembly 120 are folded for easy storage.

[0111] Furthermore, the abutting portion 1611 includes an arcuate surface and two first resisting surfaces distributed at both ends of the arcuate surface. The limiting groove 1254 is provided with two second resisting surfaces opposite to each other. When the abutting portion 1611 is located in the limiting groove 1254, each second resisting surface abuts against the corresponding first resisting surface.

[0112] Specifically, the first and second resisting surfaces are both planar structures, so that the abutting portion 1611 and the limiting groove 1254 are not regular circular structures. When the abutting portion 1611 is located in the limiting groove 1254, the first and second resisting surfaces interfere with each other, and the pressing member 161 cannot rotate within the limiting groove 1254.

[0113] Furthermore, the pressing member 161 includes a sleeve 1612. An abutment portion 1611 is disposed at one end of the sleeve 1612, which is adjacent to the body assembly 120. The abutment portion 1611 protrudes from the circumferential surface of the sleeve 1612 to form a flange. When the abutment portion 1611 is located in the slide groove 1253 and is not aligned with the limiting groove 1254, the flange abuts against a side wall of the slide groove 1253, thereby preventing the abutment portion 1611 from axially returning to the limiting groove 1254.

[0114] It is understandable that due to the setting of the first resisting surface, the distance between the axis of the pressing member 161 and the first resisting surface is smaller than the distance between the axis and the arc surface. In order to allow the abutting portion 1611 to rotate within the slide 1253, the slide 1253 needs to be set with the distance between the axis of the pressing member 161 and the arc surface as the radius. Therefore, the limiting groove 1254 is narrowed relative to the slide 1253. When the abutting portion 1611 is not completely aligned with the limiting groove 1254, the abutting portion 1611 is blocked by the connecting wall of the slide 1253 and the limiting groove 1254 and cannot return to the limiting groove 1254. This prevents the abutting portion 1611 from returning to the limiting groove 1254 when the head assembly 110 is folded, and the pressing member 161 needs to be pressed again to unfold the head assembly 110.

[0115] In some embodiments, the locking assembly 160 further includes an elastic member 162 , and both ends of the elastic member 162 are respectively connected to the pressing member 161 and the nose assembly 110 .

[0116] Specifically, the elastic member 162 can be a helical compression spring, with its two ends connected to the pressing member 161 and the handpiece assembly 110, respectively, to achieve the pressing and resetting of the pressing member 161. In normal operation, the elastic member 162 is in a stretched state, pressing the pressing member 161 outward, so that the abutment portion 1611 is located within the limiting groove 1254. During the rotation of the handpiece assembly 110, pressing the pressing member 161 causes the elastic member 162 to contract, and the abutment portion 1611 enters the slide groove 1253, causing the pressing member 161 to rotate with the handpiece assembly 110.

[0117] For example, when the nose assembly 110 is in the folded state, the elastic member 162 presses the pressing member 161 outward due to its elastic potential energy, causing the abutting portion 1611 to abut against the wall of the slide groove 1253 and prevent it from returning to the limiting groove 1254. When the nose assembly 110 is rotated to the unfolded state, the abutting portion 1611 is completely aligned with the limiting groove 1254, and the elastic member 162 presses the pressing member 161 outward, causing the abutting portion 1611 to enter the limiting groove 1254 and be unable to rotate due to the restriction of the limiting groove 1254 wall.

[0118] In some embodiments, the bracket 112 has a U-shaped notch 1331 and two oppositely disposed shafts. The rotating frame 125 is correspondingly provided with a cavity that rotates with the shafts, and the bracket 112 is rotatably connected to the rotating frame 125 through the shafts.

[0119] Furthermore, bracket 112 is equipped with multiple positioning blocks, each positioned at the end of the shaft away from rotating frame 125 and distributed circumferentially around the shaft's axis. A cavity is defined within pressing member 161, allowing pressing member 161 to be inserted into the outer side of the positioning blocks, allowing pressing member 161 to be mounted on bracket 112 and to telescopically slide relative to the positioning blocks.

[0120] Preferably, a plurality of positioning grooves can be provided inside the pressing member 161 so that when the pressing member 161 is plugged into the positioning block, the positioning block is inserted into the positioning groove, thereby achieving rapid assembly of the pressing member 161 and the bracket 112. At the same time, the cooperation between the positioning grooves and the positioning block can limit the installation angle of the pressing member 161, thereby achieving precise positioning and assembly of the pressing member 161.

[0121] Furthermore, a snap-fit ​​block is provided on one side where the bracket 112 connects to the pressing member 161, and a snap-fit ​​groove is provided on the pressing member 161. When the pressing member 161 is mounted on the bracket 112, the snap-fit ​​block engages with the snap-fit ​​groove. The snap-fit ​​block and the snap-fit ​​groove further enhance the assembly stability of the pressing member 161 and the bracket 112, and also facilitate the installation and positioning of the pressing member 161.

[0122] In some embodiments, the adjustable fan further includes a connecting assembly 170, which includes a connecting screw 171 and a locking nut 172. The connecting screw 171 sequentially passes through the rotating frame 125 and the bracket 112, so that the bracket 112 rotates relative to the rotating frame 125 about the connecting screw 171. The locking nut 172 is provided at one end of the connecting screw 171 to limit the connecting screw 171 and prevent the connecting screw 171 from falling off during rotation.

[0123] In some embodiments, the adjustable fan further includes a plurality of friction plates 150 , the rotating frame 125 is provided with a plurality of mounting slots 1255 , each friction plate 150 is respectively installed in a corresponding mounting slot 1255 , and the connecting screw 171 passes through each friction plate 150 in sequence.

[0124] Exemplarily, two friction plates 150 and two mounting slots 1255 are provided, and the two friction plates 150 are symmetrically arranged on either side of the bracket 112. During installation, the connecting screw 171 passes through one friction plate 150, the bracket 112, and the other friction plate 150 in sequence before being secured to the locking member 132. As the bracket 112 rotates, the friction plates 150 provide friction to the bracket 112, offsetting some of the potential energy of the bracket 112 during rotation, reducing the rotational speed of the bracket 112, and minimizing component wear.

[0125] Furthermore, the body assembly 120 includes an upper cover 126, which covers and is coupled to the rotating frame 125 to shield the internal cavity of the rotating frame 125. For example, the upper cover 126 and the rotating frame 125 are detachably connected. The upper cover 126 is provided with a latching block, and the rotating frame 125 has a corresponding connecting groove for engaging with the upper cover 126. In other embodiments, the upper cover 126 and the rotating frame 125 may also be fastened with screws, which is not specifically limited here.

[0126] Continue reading Figure 22 As shown, in one embodiment, the adjustable fan further includes a base plate 140 , and the second pipe 122 is detachably connected to the base plate 140 .

[0127] Specifically, the bottom of the second pipe 122 is threadedly engaged with the chassis 140 , so that during assembly, the second pipe 122 and the chassis 140 are locked, providing stable support to the fan through the chassis 140 to ensure good operation of the fan.

[0128] Continue reading Figure 23 As shown, further, the main shell 1111 has a front mesh surface 11112, and the front mesh surface 11112 is assembled and matched with the chassis 140.

[0129] Specifically, during the storage process of the fan, the second tube 122 can be rotated to separate the second tube 122 from the chassis 140, and then the front mesh surface 11112 of the main shell 1111 is placed in close contact with the chassis 140 to further reduce the storage space of the fan.

[0130] For example, the front mesh 11112 and the chassis 140 can be secured to each other by magnetic attraction or snap-fitting. In other embodiments, one side of the chassis 140 can be configured as a sloped structure with thickness decreasing toward the center to fully accommodate the front mesh 11112 of the outer shell, thereby achieving adaptive assembly of the front mesh 11112.

[0131] In addition, it should be noted that in order to achieve good folding of the adjustable fan during the folding process and ensure the normal operation and shaking of the fan, this application involves multiple parameter settings.

[0132] 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.

While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. 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.
