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 large size, large space occupation, fixed structure, single function, and inconvenient storage, which cannot meet the storage needs of users. Summary of the invention

[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 comprises a first tube, a second tube and a rotating frame, wherein the first tube and the second tube are telescopically sleeved and matched, and 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 nose assembly can be controlled to flip, unfold or fold on the fuselage assembly, the fuselage assembly has two states, extension and contraction, and the overall length of the fuselage assembly in any state is greater than the overall length of the nose 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 of the embodiments, the distance between the connection axis of the bracket and the fan head and the connection 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 disposed on a side of the rotating frame facing away from the first tube, and an axis of the first tube and a 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 also 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 operating 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 opposite to each other on the outer side of the support shaft;

[0020] A connecting column is provided in the middle of the rotating frame, and a clamping groove 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 groove.

[0021] Through the above design, after the connecting column extends into the interior of the supporting shaft, the buckle with a certain elasticity is clamped in the clamping groove of the connecting column 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 30mm-150mm.

[0023] Through the above design, the overall thickness of the fan after folding is guaranteed to be optimal.

[0024] In one of the embodiments, 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] Through the above design, it is ensured that the second pipe can be completely retracted into the first pipe, thereby ensuring the retractable adjustment range of the whole machine.

[0026] In one embodiment, the adjustable fan further includes a telescopic adjustment component, which is arranged at the connection between the first pipe and the second pipe, and the telescopic adjustment component includes a connecting piece, a locking piece and a nut piece. The connecting piece is installed at one end of the second pipe close to the first pipe and slidably penetrates the first pipe. The locking piece has a tightening end, which penetrates one end of the first pipe close to the second pipe and can tighten or disengage from the connecting piece under the action of an external force. The nut piece is installed at one end of the first pipe close to the second pipe, and the locking piece is threadedly matched with the nut piece. The locking piece is controlled to rotate relative to the nut piece to approach or move away from the connecting piece.

[0027] Wherein, when the abutting end abuts against the connecting piece, the first pipe member and the second pipe member remain relatively fixed, and 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 piece is rotated and moves relative to the nut plate, thereby achieving the abutment and separation between the abutting end of the locking piece and the connecting piece, thereby controlling the relative movement between the first pipe and the second pipe and adjusting the height of the fuselage assembly.

[0029] In one embodiment, the telescopic adjustment assembly also includes a sleeve, which is fixed to one end of the first tube close to the second tube, and the connecting member is slidably passed through the sleeve and has a flange edge at one 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] Through the above design, under the restriction of the flange edge, the second pipe member cannot be separated from the first pipe member, which facilitates the telescopic adjustment of the second pipe member.

[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] Through the above design, the abutting end of the locking member can be pressed against the surface of the connecting member through the notch 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 arranged abutment surface.

[0034] With the above design, when the locking member abuts, the pressing block can abut against the connecting member to limit 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 and separated 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 with the related art, the beneficial effect of the present application is as follows: the present application provides an adjustable fan, which can facilitate the folding and storage of the fan.

[0072] See also 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, wherein the head assembly 110 and the body assembly 120 are rotatably connected, so that the head assembly 110 can be rotated relative to the body assembly 120 to adjust the operating angle of the head assembly 110. At the same time, during the storage process of the fan, the head assembly 110 and the body assembly 120 can be folded by rotating the head assembly 110 to reduce 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 pipe 121, a second pipe 122 and a rotating frame 125. The first pipe 121 and the second pipe 122 can be telescopically sleeved together. The rotating frame 125 is installed at one end of the first pipe 121 facing away from the second pipe 122 and is rotatably connected to one 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 body assembly 120. The body assembly 120 has two states: extended and contracted. The overall length of the body 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 body assembly 120 after folding, and sufficient folding space is reserved for the head assembly 110 to ensure the supporting function of the body assembly 120 after folding.

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

[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 approximately the same as the length of the body assembly 120 after contraction, thereby ensuring the minimum size after folding.

[0078] Furthermore, the fuselage assembly 120 further includes an upper cover 126 which is disposed on the side of the rotating frame 125 facing away from the first tube 121, and an intersection o exists between the axis of the first tube 121 and the side of the upper cover 126 facing away from the rotating frame 125. When the head assembly 110 is unfolded on the fuselage assembly 120, the distance between the end of the fan head 111 close to the upper cover 126 and the intersection o is D2, and D2 is 10 mm-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. The specific design can be based on actual needs to ensure that the fan head 111111 has enough space to avoid shaking the head.

[0080] Furthermore, the body assembly 120 further includes a rotating sleeve 123 and a supporting shaft 124, the rotating sleeve 123 is sleeved on one end of the first tube 121 away from the second tube 122, the supporting shaft 124 is installed in the rotating sleeve 123, and the rotating frame 125 is clamped on one end of the supporting shaft 124 away from the rotating sleeve 123 and is rotatably connected to the head assembly 110. One end of the rotating frame 125 connected to the bracket 112 extends to the outside of the first tube 121, so as to facilitate the rotation and folding of the head assembly 110, and make the center of gravity of the whole machine fall on the axis of the body assembly 120, so as to ensure the operation stability of the whole 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 specifically 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 specifically designed according to actual needs to ensure that the overall thickness of the fan after folding is optimal.

[0085] Furthermore, the distance between the 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. It can be specifically designed according to actual needs to ensure that the second pipe 122 can be completely retracted into the first pipe 121 to ensure the retractable adjustment range of the whole machine.

[0087] Continue reading Figure 3 As shown, further, the adjustable fan also includes a telescopic adjustment component 130, the fuselage component 120 includes a first pipe 121 and a second pipe 122 that are sleeved together, and the telescopic adjustment component 130 is installed at the connection between the first pipe 121 and the second pipe 122 to adjust the connection length of the first pipe 121 and the second pipe 122. When the telescopic adjustment component 130 locks the first pipe 121 and the second pipe 122, the first pipe 121 and the second pipe 122 remain relatively fixed, ensuring the connection strength during the operation process, and providing stable support for the fan as a whole. When the telescopic adjustment component 130 does not lock the first pipe 121 and the second pipe 122, the second pipe 122 can be telescopically moved in the first pipe 121 to adjust the operating height of the fan, and during the storage process, the second pipe 122 can be completely sleeved in the first pipe 121, further reducing the occupied space.

[0088] Specifically, the telescopic adjustment assembly 130 includes a connecting member 131 and a locking member 132. The connecting member 131 is installed at one end of the second pipe 122 close to the first pipe 121 and is slidably arranged in the first pipe 121, so that during the contraction process of the second pipe 122, the connecting member 131 follows the second pipe 122 to contract in the first pipe 121. The locking member 132 has a tight end 1321, which is arranged at one end of the first pipe 121 close to the second pipe 122 and can move along its own axis compared to the first pipe 121, so as to be pressed against or separated from the connecting member 131 under the action of external force. In this way, when the tight end 1321 is pressed against the connecting member 131, the first pipe 121 and the second pipe 122 remain relatively fixed, and when the tight end 1321 is separated from the connecting member 131, the first pipe 121 can slide relative to the second pipe 122.

[0089] Continue reading Figure 4 and Figure 5 As shown, illustratively, one end of the connector 131 is plugged into one end of the second pipe 122 close to the first pipe 121, and corresponding screw holes are provided at one end of the connector 131 inserted into the second pipe 122 and one end of the second pipe 122 close to the first pipe 121. Thus, after the connector 131 is inserted into the second pipe 122, the screw holes of the connector 131 and the second pipe 122 are aligned and locked by screws to achieve assembly of the connector 131 and the second pipe 122.

[0090] Continue reading Figure 6 and Figure 7 As shown, the locking member 132 is exemplarily a knob structure, one end of which is a cap structure, and the other end is a threaded rod. A hole is provided at one end of the first pipe 121 close to the second pipe 122, so that the threaded rod passes through the hole and is inserted into the first pipe 121. At the same time, the threaded rod is threadedly matched with the first pipe 121, so that the threaded rod can be controlled to penetrate into or away from the first pipe 121 by rotating the cap, thereby controlling the abutting end to abut or separate from the connecting member 131 located in the first pipe 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 one end of the first pipe 121 close to the second pipe 122. The connector 131 is slidably arranged in the sleeve 133 and is provided with a flange edge 1311 at one end away from the second pipe 122. When the first pipe 121 reaches the maximum stretching position, the flange edge 1311 is pressed against the end of the sleeve 133.

[0092] Specifically, after the connector 131 and the second pipe 122 are assembled, the sleeve 133 is sleeved on the outside of the connector 131, and the flange 1311 is provided to limit the sleeve 133 from being separated from one side of the connector 131. Then, the sleeve 133 and the second pipe 122 are simultaneously inserted into the first pipe 121, the sleeve 133 is aligned with the screw holes corresponding to the first pipe 121, and the sleeve 133 and the first pipe 121 are locked by screws, so that the second pipe 122 and the connector 131 are inserted into the first pipe 121, and under the restriction of the flange 1311, the second pipe 122 cannot be separated from the first pipe 121, so that the telescopic adjustment of the second pipe 122 is convenient.

[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 abut against the surface of the connecting member 131 to limit the movement of the second pipe member 122 .

[0094] Continue reading Fig. 9 As shown, further, the telescopic adjustment assembly 130 also includes a pressing block 134, which has a plurality of retaining ribs 1341, and the sleeve 133 is correspondingly 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 the assembly process, each retaining rib 1341 of the pressing block 134 is clamped on each abutting surface 1332, so that the pressing block 134 is installed at the notch 1331 of the shaft sleeve 133. Due to the setting of the retaining rib 1341, the pressing block 134 has a certain elasticity, so that under the abutment of the locking member 132, the pressing block 134 can abut against the connecting member 131 to limit the movement of the second pipe 122. When the locking member 132 is released, the pressing block 134 can be reset under the action of the elastic force, separated from the connecting member 131, and the second pipe 122 can resume movement.

[0096] Continue reading Fig.10 As shown, further, the telescopic adjustment assembly 130 also includes a fixing block 135, and the fixing block 135 and the pressing block 134 are respectively provided with mutually matching clamping blocks and clamping grooves, so that the fixing block 135 is installed on the side of the pressing block 134 away from the shaft sleeve 133. In this way, the abutting end of the locking member 132 abuts against the fixing block 135, but does not directly contact the pressing block 134, thereby reducing the wear of the pressing block 134.

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

[0098] See also Fig.12 As shown, a receiving groove 1211 is provided at the bottom of the first pipe 121, 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 with 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 abutment and separation of 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 an operating component of the fan to deliver wind to the user during operation. Through the setting of the bracket 112, during operation, the fan head 111 can rotate relative to the bracket 112 to adjust the operating angle. At the same time, when folded and stored, the fan head 111 can be in a 0° folded state with the body assembly 120 through the bracket 112.

[0100] Continue reading Fig.13 and Fig.14 As shown, specifically, the fan head 111 includes a main housing 1111, a rotating shaft 1112 and a cover plate 1113. A convex 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 fitted with the convex rib 11111. The cover plate 1113 is sleeved on the end of the rotating shaft 1112 away from the gear ring 11121, and 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 convex rib 11111 are both provided with corresponding screw holes. After the screw holes of the cover plate 1113 and the convex rib 11111 are aligned, the cover plate 1113 and the convex rib 11111 are locked 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 111.

[0101] Furthermore, the fan head 111 also includes an upper shell 1114 and a lower shell 1115 , and 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 Fig.15 As shown, the bracket 112 includes a frame body 1121 and a cover body 1122. The cover body 1122 and the frame body 1121 can be respectively provided with a clamping block and a clamping groove to achieve assembly and cooperation between them. In other embodiments, the cover body 1122 and the frame body 1121 can also be locked with screws, which is not specifically limited here.

[0103] Exemplarily, the bracket 112 is in a Y-shaped structure, and its bottom end is rotatably connected to the fuselage assembly 120. Mounting holes are provided at the upper ends of the bracket 112, and two rotating shafts 1112 are provided and distributed on two opposite sides of the main housing 1111, so that the two rotating shafts 1112 are fixed to the two mounting holes by screws. In this way, the fan head 111 is installed between the upper ends of the bracket 112 and is rotatably connected to the upper ends of the bracket 112, thereby achieving stable installation of the fan head 111, and during operation, the fan head 111 can rotate relative to the bracket 112 to adjust the operating angle.

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

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

[0106] See also Fig.18 and Fig.19 As shown, further, a support column 1241 is provided in the middle of the support shaft 124, and two buckles 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 clamping groove 1252 is provided on the peripheral side of the connecting column 1251, so that after the connecting column 1251 is sleeved on the outer side of the support column 1241, the two buckles 1242 are clamped in the clamping groove 1252.

[0107] Specifically, the rotating frame 125 is sleeved on the outside of the rotating sleeve 123, and the connecting column 1251 is sleeved on the outside of the supporting column 1241, thereby strengthening the connection between the rotating frame 125 and the first pipe 121. At the same time, after the connecting column 1251 extends into the interior of the supporting shaft 124, the buckle 1242 with a certain elasticity is clamped in the clamping groove 1252 of the connecting column 1251 under the action of elastic force, further strengthening the installation stability of the rotating frame 125.

[0108] See also Fig. 20 and Fig.21 As shown, in some embodiments, the adjustable fan also includes a locking assembly 160, the locking assembly 160 includes a pressing piece 161, the rotating frame 125 is provided with a sliding groove 1253 and a limiting groove 1254 that are interconnected, the pressing piece 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 piece 161 can be telescopically inserted into 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 one end of the pressing member 161 away from the pressing surface, and 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] Exemplarily, 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 abuts against the abutment 1611, so that the pressing member 161 cannot rotate arbitrarily, thereby limiting the rotation of the head assembly 110, maintaining the stability of the head assembly 110 in the unfolded state, without the need to set up 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 is separated from the wall surface of the limiting groove 1254 and enters the interior of the slide groove 1253. The abutment 1611 can move with the head assembly 110 in the slide groove 1253, and then the head assembly 110 is 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 resisting surface and the second resisting surface 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 resisting surface conflicts with the second resisting surface, and the pressing member 161 cannot rotate in the limiting groove 1254.

[0113] Furthermore, the pressing member 161 includes a sleeve 1612, and the abutment portion 1611 is disposed at one end of the sleeve 1612 close to the fuselage assembly 120, and protrudes relative to the peripheral surface of the sleeve 1612 to form a flange surface. When the abutment portion 1611 is located in the slide groove 1253 and is not aligned with the limiting groove 1254, the flange surface abuts against a side wall of the slide groove 1253 to limit the abutment portion 1611 from being reset axially into 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, and in order to allow the abutting portion 1611 to rotate in the slide groove 1253, the slide groove 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 groove 1253, and 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 groove 1253 and the limiting groove 1254 and cannot be reset to the limiting groove 1254, thereby avoiding the abutting portion 1611 from being reset to the limiting groove 1254 in the folded state of the head assembly 110, 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 two ends of the elastic member 162 are respectively connected to the pressing member 161 and the head assembly 110 .

[0116] Specifically, the elastic member 162 may be a helical compression spring, and its two ends are respectively connected to the pressing member 161 and the handpiece assembly 110 to achieve the pressing and resetting of the pressing member 161. In the normal state, the elastic member 162 is in a stretched state, pressing the pressing member 161 outward, so that the abutting portion 1611 is located in the limiting groove 1254. During the rotation of the handpiece assembly 110, by pressing the pressing member 161, the elastic member 162 contracts, the abutting portion 1611 enters the slide groove 1253, and the pressing member 161 rotates with the handpiece assembly 110.

[0117] Exemplarily, when the nose assembly 110 is in the folded state, the elastic member 162 presses the pressing member 161 outward due to the elastic potential energy, so that the abutting portion 1611 is pressed against the wall of the slide groove 1253 and cannot be reset to enter the limit groove 1254. When the nose assembly 110 is rotated to the unfolded state, the abutting portion 1611 is completely aligned with the limit groove 1254, and the elastic member 162 presses the pressing member 161 outward, so that the abutting portion 1611 enters the limit groove 1254 and cannot rotate under the restriction of the wall of the limit groove 1254.

[0118] In some embodiments, the bracket 112 has a U-shaped notch 1331 and two shafts disposed opposite to each other. 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, the bracket 112 is also provided with a plurality of positioning blocks, each of which is provided at one end of the shaft body away from the rotating frame 125 and is circumferentially distributed with the axis of the shaft body as the axis. A cavity is provided inside the pressing member 161 so that the pressing member 161 can be inserted into the outer side of the positioning block, so that the pressing member 161 is installed on the bracket 112 and can telescopically slide relative to the positioning block.

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

[0121] Furthermore, a clamping block is provided on one side where the bracket 112 is connected to the pressing member 161, and a clamping groove is provided on the pressing member 161 accordingly, so that after the pressing member 161 is installed on the bracket 112, the clamping buckle and the clamping groove are clamped and matched. The connection and matching between the clamping buckle and the clamping groove further improves the assembly stability of the pressing member 161 and the bracket 112, and also facilitates 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 passes through the rotating frame 125 and the bracket 112 in sequence, so that the bracket 112 rotates relative to the rotating frame 125 with the connecting screw 171 as the axis. 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 the rotation process.

[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 grooves 1255 are provided, and the two friction plates 150 are symmetrically arranged on both sides of the bracket 112. During the installation process, the connecting screw 171 passes through one friction plate 150, the bracket 112 and the other friction plate 150 in sequence and is fixed to the locking member 132, so that during the rotation process of the bracket 112, the friction plate 150 will provide friction to the bracket 112, offset part of the potential energy of the bracket 112 during the rotation process, reduce the rotation speed of the bracket 112, and reduce the loss of components.

[0125] Furthermore, the body assembly 120 further includes an upper cover 126, which covers the rotating frame 125 and is connected to the rotating frame 125 to shield the internal cavity of the rotating frame 125. Exemplarily, the upper cover 126 and the rotating frame 125 are detachably connected, the upper cover 126 is provided with a clamping block, and the rotating frame 125 is correspondingly provided with a connecting groove to be clamped with the upper cover 126. In other embodiments, the upper cover 126 and the rotating frame 125 can also be locked with screws, which is not specifically limited here.

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

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

[0128] Continue reading Fig.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 pipe 122 can be rotated to separate the second pipe 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] Exemplarily, the front mesh surface 11112 and the chassis 140 may be magnetically matched or snap-fitted to fix the front mesh surface 11112 and the chassis 140. In other embodiments, one side of the chassis 140 may be configured as an inclined structure whose thickness decreases toward the center to completely accommodate the front mesh surface 11112 of the outer shell, thereby achieving adaptive assembly of the front mesh surface 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 of the fan, this application involves multiple parameter settings.

[0132] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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.
