DETAILED DESCRIPTION

[0037] In order to facilitate the understanding of the present application, the present application will be described in more detail below in conjunction with the drawings and specific embodiments. It should be noted that when an element is described as being "fixed to" another element, it can be directly on the other element or one or more intervening elements can be present therebetween. When an element is described as being "connected to" another element, it can be directly connected to the other element or one or more intervening elements can be present therebetween. The terms "vertical", "horizontal", "left", "right", and similar expressions used in the present specification are for illustrative purposes only.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. All publications, patent applications, patents, and other references mentioned herein are incorporated by reference in their entirety for the teachings relevant to the sentence and / or paragraph in which the reference is presented.

[0039] In the prior art, the fan includes a fan head, a base and a battery, the fan head is installed on the base, the battery is electrically connected with the fan head, the fan head is used for outputting wind power, and the main function of the base is to lift the fan head and provide support. In the existing market, the base of the upright fan lifts the fan head by about one-third or one-fourth of the height of the human body relative to the ground, and when the upright fan is applied in the complex outdoor environment, for example, the uneven and wet ground, the fan is easy to fall down, and the wet soil on the ground is easy to cover the fan, so that the fan is difficult to clean, and when the fan is placed on the car or carried by hand, the wet soil adhered to the fan is easy to stick to the clothes of the user. In other words, the application scene of the fan in the prior art is too single.

[0040] In addition, the battery endurance needs to be improved in outdoor environment to provide better use guarantee for the user, and the weight of the battery is usually heavy, which accounts for about one-half or two-fifths of the weight of the fan. In order to improve the stability of the fan, the battery is placed in the base, for example, at the bottom end of the base, so as to make the center of gravity of the fan close to the ground, thereby improving the stability of the support of the base. When the height of the fan head relative to the ground is higher, the fan is more sensitive to external force disturbance, and the moment is large, so that the fan is easy to lose stability, resulting in falling down or breaking.

[0041] The utility model provides a kind of fan 100 of multiple scene use, fan 100 can adapt to complex environment in outdoor, the following is the structure of fan 100 of multiple scene use.

[0042] Please refer to Figure 1 Fan 100 includes fan head assembly 10, energy storage assembly 20 and support mechanism 30. Fan head assembly 10 is arranged at one end of energy storage assembly 20, and support mechanism 30 is detachably connected to the other end of energy storage assembly 20, so as to carry and lift fan head assembly 10, so that fan 100 stands on the ground. When support mechanism 30 and energy storage assembly 20 are in a detached state, energy storage assembly 20 can form a first base, and energy storage assembly 20 can stably stand on a table top or be hung on a to-be-fixed object. When support mechanism 30 and energy storage assembly 20 are in a connected state, one end of support mechanism 30 is in contact with the ground, so that support mechanism 30 carries and lifts fan head assembly 10, so that fan 100 stands on the ground.

[0043] Please refer to Figures 2 to 5 , the fan head assembly 10 comprises a bracket 11 and a fan 12. One end of the bracket 11 is rotatably connected to the fan 12, and one end of the energy storage assembly 20 is rotatably connected to the other end of the bracket 11. The bracket 11 can rotate relative to the energy storage assembly 20 in a first direction R1, and the fan 12 can rotate relative to the bracket 11 in a second direction R2.

[0044] Please refer to Figure 3 and Figure 4 , the bracket 11 has a U-shaped structure. Specifically, the bracket 11 comprises a connecting portion 111 and two bent portions 112; one bent portion 112 is connected to one end of the connecting portion 111, and the other bent portion 112 is connected to the other end of the connecting portion 111, and the two bent portions 112 are oppositely arranged to form a turnover space 10a together with the connecting portion 111, the first bent portion 112 and the second bent portion 112. The fan 12 is arranged in the turnover space 10a, and the fan 12 is rotatably connected to at least one bent portion 112, so that the fan 12 can be turned over in the second direction R2, thereby adjusting the angle of the fan 12.

[0045] Please refer to Figure 5 , the fan 12 comprises a fan shell 123, fan blades 124 and a motor 125. The fan 12 is provided with a receiving cavity 12b, an air inlet hole 12c and an air outlet hole 12d, the fan blades 124 are arranged in the receiving cavity 12b, the air inlet hole 12c and the air outlet hole 12d are oppositely arranged and respectively communicated with the receiving cavity 12b, the driving shaft of the motor 125 is communicated with the fan blades 124, and the motor 125 is electrically connected with the energy storage assembly 20. When the motor 125 is powered, the motor 125 drives the fan blades 124 to rotate relative to the fan shell 123, so that the gas in the receiving cavity 12b exchanges with the outside. In addition, at least part or more than half of the fan blades 124 are exposed to the field of view in the projection direction perpendicular to the connecting line direction of the air inlet hole 12c and the air outlet hole 12d, so that the gas is more easily introduced into the air inlet hole 12c.

[0046] Please refer to Figure 3 and Figure 4 , the fan 12 is rotatably connected to the bent portion 112, the fan 12 is provided with a first rotating shaft 121, the bracket 11 is provided with a first rotating hole 11a, the first rotating shaft 121 is inserted into the first rotating hole 11a, and the first rotating shaft 121 is matched with the first rotating hole 11a, so that the first rotating shaft 121 can rotate relative to the first rotating hole 11a, thereby realizing the rotation of the fan 100 relative to the bracket 11 in the second direction R2.

[0047] In some embodiments, the fan head assembly 10 further comprises a wind power adjusting member (such as Figure 3The wind power adjusting member button is used to adjust the power of the energy storage assembly 20 to the motor 125. When the current inputted from the energy storage assembly 20 to the motor 125 is greater, the wind power outputted from the fan 12 is greater. The wind power adjusting member can be in the form of a button. For example, when the button is pressed for the first time, the fan 12 outputs a small wind power. With the number of times of pressing the button, the wind power outputted from the fan 12 gradually increases. When the fan 12 reaches the maximum power value, the last time of pressing is to disconnect the electrical connection between the energy storage assembly 20 and the motor 125. Of course, the wind power adjusting member can also be in the form of a knob. For example, when the knob is rotated clockwise, the wind power outputted from the fan 12 gradually decreases. When the knob is rotated counterclockwise, the wind power outputted from the fan 12 gradually increases.

[0048] In some embodiments, the fan head assembly 10 further comprises an angle maintaining structure 13, which is used to maintain a preset angle of the air outlet vertical plane of the fan 12 relative to the ground. Specifically, the angle maintaining structure 13 comprises a gear member 131 fixed to the support 11 and an elastic member 132, one end of which is fixed to the fan 12 and the other end of which abuts against the gear member 131. When it is needed to adjust the rotation of the fan 12 along the second direction R2 and maintain the preset angle, an action force along the second direction R2 is applied to the fan 100. When the action force is sufficient to overcome the friction between the elastic member 132 and the gear member 131, the fan 12 rotates relative to the support 11. When the fan 12 loses the action force, the gravity of the fan 12 cannot overcome the friction between the elastic member 132 and the gear member 131, so that the fan 12 maintains the preset angle relative to the ground.

[0049] Further, the gear member 131 comprises a plurality of tooth portions 1311, which are arranged in the radial direction of the first rotation shaft 121 and form a tooth groove between adjacent two tooth portions. The other end of the elastic member 132 is matched with the tooth groove and abuts against the tooth groove. When the action force along the second direction R2 is applied to the fan 12 and the action force is sufficient to overcome the friction between the elastic member 132 and the gear member 131, the elastic member 132 elastically deforms and changes from abutting against the current tooth groove to abutting against the adjacent tooth groove.

[0050] In some other embodiments, the support 11 is provided with a first driving member, for example, a motor. The driving shaft of the first driving member is connected with the first rotation shaft 121 of the fan 12. When the driving shaft of the first driving member is driven to rotate, the driving shaft of the first driving member drives the fan 12 to rotate relative to the support 11, thereby solving the problem of manually applying the action force.

[0051] Please refer to Figure 2 The top of the fan 100 is provided with a handle 14 connected with the fan 12, which is used for the user to carry.

[0052] Optionally, the fan 12 is further provided with a recess 15 for receiving the handle 14, and the handle 14 is rotatably connected to the fan 12. When it is needed to hang or carry the fan 12, the handle 14 is only needed to be rotated to protrude or stretch out relative to the fan 12, so as to facilitate the user to transport; when the handle 14 is not needed to be used, the handle 14 is rotated to be received in the recess 15 relative to the top of the fan 12.

[0053] Optionally, the handle 14 can be a flexible material, such as a leather material or a rope, so as not to worry about the risk of breaking the handle 14.

[0054] Please refer to Figure 3 , the fan 100 is provided with the lighting lamp 122 on the air outlet surface. In the embodiment, the lighting lamp 122 is arranged along the outer periphery of the fan 100, and the lighting lamp 122 has a constant mode and a flashing mode, and the constant mode includes different brightness levels, so as to solve the different brightness needs of the user. At the same time, the fan 100 is further provided with a brightness adjusting member (as shown in Figure 3 ) for adjusting the brightness of the lighting lamp 122, for example, the brightness adjusting member can be in the form of a button, for example, when the button is pressed for the first time, the lighting lamp 122 outputs a very small brightness, and with the number of times of pressing the button, the brightness output by the lighting lamp 122 gradually increases, and when the lighting lamp 122 reaches the maximum power value, the last time of pressing is to disconnect the electrical connection between the energy storage assembly 20 and the lighting lamp 122; of course, it can also be in the form of a knob, for example, when the knob is rotated clockwise, the brightness output by the lighting lamp 122 gradually decreases, and when the knob is rotated counterclockwise, the brightness output by the lighting lamp 122 gradually increases.

[0055] Please refer to Figure 3 , the energy storage assembly 20 is in a square structure, the energy storage assembly 20 is located at one end of the support 11 away from the turnover space 10a, and the energy storage assembly 20 is rotatably connected with the support 11, so that the support 11 can be rotated relative to the energy storage assembly 20 in the first direction R1, so as to realize that the fan 100 outputs wind power in different radial directions with itself as the center. Specifically, the energy storage assembly 20 includes an outer shell 21 and a secondary battery, one end of the outer shell 21 is rotatably connected with the support 11, the other end of the outer shell 21 is detachably connected with the supporting mechanism 30 (see Figure 1 ), the outer shell 21 is provided with an inner cavity, the secondary battery is arranged in the inner cavity, and the secondary battery is used to provide electrical energy for the fan 100. The secondary battery includes one or more than two of a nickel-hydrogen battery, a nickel-cadmium battery, a lead-acid (or lead storage) battery, a lithium ion battery, and a polymer lithium ion battery.

[0056] The shell 21 is rotationally connected with the support 11, and a second rotation shaft 211 is fixedly arranged at the top of the inner cavity close to the support 11. The support 11 is provided with a second rotation hole 11b, the inner cavity and the second rotation hole 11b are in communication with each other, and the second rotation shaft 211 is inserted into the second rotation hole 11b, so that the energy storage assembly 20 can rotate relative to the support 11.

[0057] In some embodiments, the fan head assembly 10 further comprises a second driving member, for example, a motor, the second driving member is fixed to the support 11, and a driving shaft of the second driving member is fixed to the energy storage assembly 20. When the driving shaft of the second driving member is driven to rotate, the fan head assembly 10 rotates relative to the energy storage assembly 20, further solving the problem of manually applying force.

[0058] Please refer to Figures 6 to 8 , one end of the shell 21 away from the fan head assembly 10 is detachably connected with the supporting mechanism 30 (see Figure 1 ), and the specific connection mode includes but is not limited to threaded connection, clamping, magnetic connection, plug-in connection and the like. In this embodiment, the shell 21 and the supporting mechanism 30 are threaded, and one end of the energy storage assembly 20 away from the fan head assembly 10 is a flat end face, so that the energy storage assembly 20 can be stably placed on the ground or the desktop, further forming the first base of the energy storage assembly 20.

[0059] Specifically, one end of the supporting mechanism 30 close to the shell 21 is formed with a thread, and the bottom of the shell 21 is provided with a threaded hole corresponding to the thread, the threaded hole and the inner cavity of the shell 21 are in communication with each other, when the supporting mechanism 30 needs to be installed with the shell 21, the threaded connection is used to realize the connection of the supporting mechanism 30 and the energy storage assembly 20, when the supporting mechanism 30 needs to be separated from the shell 21, so that the shell 21 is installed on the desktop, only need to rotate the supporting mechanism 30.

[0060] Further, the bottom of the shell 21 is provided with an anti-skid pad 29, when the energy storage assembly 20 forms the second base and is placed on the desktop 300, the anti-skid pad 29 can enhance the friction between the energy storage assembly 20 and the desktop 300, and reduce the possibility of the energy storage assembly 20 being dumped on the desktop 300 under the action of external force.

[0061] Further, the bottom of the energy storage assembly 20 is further recessed inwardly with a clamping groove 25, and the energy storage assembly 20 is rotationally connected with a hook 26, the hook 26 is in a circular arc structure, the shape of the hook 26 is matched with the clamping groove 25, and the hook 26 has a storage state and an unfolded state, when the hook 26 is in the storage state (as Figure 6As shown in the figure, the hook 26 can be stably clamped in the clamping groove 25, and when the hook 26 is in the unfolded state, the hook 26 is separated from the clamping groove 25 and protrudes relative to the energy storage assembly 20, so that the hook 26 can be hung on the object to be hung, so as to hang the fan upside down, for example, the hook 26 is hung on the branch of the tree, and the energy storage assembly 20 is hung on the tree. Figure 9 The schematic diagram is made.

[0062] Further, the outlet end of the clamping groove 25 protrudes a limiting structure, which is used for clamping the hook 26 in the clamping groove 25 and avoiding the hook 26 from being separated from the clamping groove 25 by itself without external force. The limiting structure has good elastic deformation, so that the hook 26 can extrude the limiting structure from outside to inside to be clamped in the clamping groove 25, or extrude the limiting structure from inside to outside to be separated from the clamping groove 25.

[0063] Further, in order to facilitate the hook 26 to be taken out of the clamping groove 25, a first groove 27 is outwardly recessed on one side of the clamping groove 25, and the first groove 27 and the clamping groove 25 are in communication with each other, so that more hooks 26 are exposed to the field of view, so that the hook 26 has more contact area, thereby facilitating the user to take out the hook. In order to facilitate the hook 26 to be better taken out, the hook 26 extends an extension 28 towards the first groove 27, thereby facilitating the user to apply force.

[0064] The energy storage assembly 20 is provided with a mounting groove 22 and a charging port 23 and a discharging port 24. The mounting groove 22 is used for mounting and clamping the remote controller 40 for controlling the circuit switch and the rotating direction of the fan 100. The charging port 23 and the discharging port 24 are connected with the energy storage assembly 20, and at the same time, the charging port 23 and the discharging port 24 are used for connecting with the external connector, so as to facilitate the charging or discharging of the energy storage assembly 20.

[0065] Optionally, the bottom wall of the mounting groove 22 further protrudes a spring 212, and the slot of the mounting groove 22 is provided with a limiting edge 213. When the remote controller 40 is placed in the mounting groove 22, the spring and the limiting edge jointly clamp the remote controller 40. When the remote controller 40 needs to be taken out of the mounting groove 22, the external force only needs to overcome the friction between the spring 212 and the limiting edge 213 and the remote controller 40.

[0066] Further, an opening 22a is formed on one end of the mounting groove 22 close to the fan head, and the opening 22a is used for taking out the remote controller 40 from the mounting groove 22. The housing 21 is further provided with a second groove 22b, and the opening 22a and the second groove 22b are oppositely arranged on the mounting groove 22, and the second groove 22b is in communication with the mounting groove 22. The second groove 22b is used for applying force to the remote controller 40 from the second groove 22b to the mounting groove 22, so that the remote controller 40 is stretched out of the opening 22a, thereby facilitating the user to take out the remote controller 40.

[0067] It can be understood that the remote controller 40 can control the circuit of the fan 100 as a whole, and drive the fan 100 to start, rotate in different directions, and stop rotating. Meanwhile, the remote controller 40 can also control the lighting lamp 122 on the fan 100 to start or turn off.

[0068] Optionally, a sealing piece is arranged at the charging port 23 and the discharging port 24, and the sealing piece is used to open or close the charging port 23 and the discharging port 24, so as to reduce the rainwater entering the charging port 23 and the discharging port 24, on the one hand, to avoid rusting of the charging port 23 and the discharging port 24, and on the other hand, to reduce the risk of the rainwater entering the charging port 23 and the discharging port 24, so as to avoid short circuit of the charging port 23 and the discharging port 24.

[0069] Optionally, the sealing piece is made of waterproof material, for example, silica gel or rubber.

[0070] Please refer to Figure 10 and Figure 11 The support mechanism 30 comprises a telescopic assembly 31, which is detachably connected to the energy storage assembly 20, and is used to adjust the height of the fan head assembly 10 relative to the ground, so as to meet the different blowing height requirements of the user and also meet the requirement of the user for convenient carrying. In addition, the smaller the distance between the fan head assembly 10 and the ground or the table top, the higher the stability of the fan 100, and the less likely the fan 100 is to fall down.

[0071] The telescopic assembly 31 is detachably connected to the energy storage assembly 20, for example, the detachable connection modes include screwing and clamping. The end of the energy storage assembly 20 away from the fan head assembly 10 is provided with a threaded hole, and the telescopic assembly 31 is provided with a threaded part which is screwed into the threaded hole.

[0072] In some embodiments, the telescopic assembly 31 comprises a plurality of rod members, one end of the plurality of rod members is detachably connected to the energy storage assembly 20, and the other end of the plurality of rod members is connected to the support assembly 33. The plurality of rod members has an elongated state and a shortened state. When the plurality of rod members is in the elongated state, in the adjacent two rod members (for the convenience and better explanation of the telescopic assembly, one of the adjacent two rod members is referred to as a first rod, and the other is referred to as a second rod), the first rod 311 extends relative to the second rod 312, and when the telescopic assembly 31 is in the shortened state, in the adjacent two rod members, the first rod 311 at least partially sleeves the second rod 312 or completely sleeves.

[0073] Please refer to Figure 11 The support mechanism 30 further comprises a locking assembly 32, which has an unlocked state and a locked state. When the locking assembly 32 is in the unlocked state, the adjacent two rod members can move relative to each other or move away from each other, and when the locking assembly 32 is in the locked state, the movement between the adjacent two rod members is not allowed.

[0074] Referring to Figure 12 In some embodiments, the locking assembly 32 comprises a first eccentric structure 321 and an elastic pad 322. Among the two adjacent rods, the first rod 311 with a larger diameter extends in a radial direction with an extension 3111, the first eccentric structure 321 is rotationally connected to the extension 3111, and the first rod 311 is provided with a through hole 311a in a radial direction, and the elastic pad 322 is inserted into the through hole 311a. When the first eccentric structure 321 is driven to rotate relative to the extension 3111, the first long diameter part 3211 of the first eccentric structure 321, the center line of the elastic pad 322 and the central axis of the second rod 312 form a straight line, the first long diameter part 3211 of the first eccentric structure 321 presses the elastic pad 322, so that the elastic pad 322 abuts against the second rod 312, thereby preventing the adjacent two rods from moving relative to or away from each other, when the first short diameter part 3212 of the first eccentric structure 321, the center line of the elastic pad 322 and the central axis of the second rod 312 form a straight line, a gap is formed between the elastic pad 322 and the second rod 312, thereby allowing the adjacent two rods to move relative to or away from each other. In addition, in order to facilitate the user to apply an external force to the first eccentric structure 321, the first eccentric structure 321 extends with a handle part 3213. It should be noted that in the present embodiment, the direction in which the center line of the elastic pad 322 extends is the same as the axial direction of the second rod 312, and the central axis of the second rod 312 is the central axis of the axial direction of the second rod 312.

[0075] Please refer to Figure 13In some embodiments, the locking assembly 32 comprises a second eccentric structure 323, a clamping sleeve 324, a screw rod 325 and a nut 326. Between two adjacent rods, one end of the clamping sleeve 324 is fixed to the first rod 311, and the other end of the clamping sleeve 324 is sleeved on the second rod 312. The clamping sleeve 324 is provided with an opening 324a from the outer wall to the inner wall, and the opening 324a has a first side wall portion 3241 and a second side wall portion 3242 on opposite sides. The clamping sleeve 324 is provided with a through hole 324b penetrating from the first side wall portion 3241 to the second side wall portion 3242. The second eccentric structure 323 is arranged on the side of the first side wall portion 3241 away from the second side wall portion 3242. The nut 326 is arranged on the side of the second side wall portion 3242 away from the first side wall portion 3241. One end of the screw rod 325 is rotationally connected to the second eccentric structure 323. The other end of the screw rod 325 is screwed to the nut 326 after being inserted into the through hole 324b. The second eccentric structure 323 can reciprocate between a first preset position and a second preset position. When the second eccentric structure 323 is at the first preset position, the second long diameter portion 3231 of the second eccentric structure 323 and the nut 326 jointly clamp the first side wall portion 3241 and the second side wall portion 3242. The first side wall portion 3241 and the second side wall portion 3242 drive the clamping sleeve 324 to clamp the second rod 312, so that the first rod 311 is locked relative to the second rod 312. When the second eccentric structure 323 is at the second preset position, there is at least one gap between the second short diameter portion 3232 of the second eccentric structure 323 and the first side wall portion 3241, and between the nut 326 and the second side wall portion 3242 and the nut 326. Therefore, the clamping sleeve 324 no longer clamps the second rod 312, i.e. the first rod 311 is unlocked relative to the second rod 312. When adjusting the length of the telescopic assembly 31, when the second eccentric structure 323 changes from the first preset position to the second preset position or from the second preset position to the first preset position, the clamping sleeve 324 clamps the second rod 312 or the clamping sleeve 324 has a gap with the second rod 312, so as to realize the locking or unlocking between two adjacent rods. In addition, by rotating the nut 326, the nut 326 moves relative to the screw rod 325, so as to adjust the distance between the second eccentric structure 323 and the nut 326, and further adjust the tightness of the clamping sleeve 324 clamping the second rod 312.

[0076] Please refer to Figure 14 The support mechanism 30 further comprises a support assembly 33. The support assembly 33 has an unfolded state and a folded state. When the support assembly 33 is in the unfolded state, the support assembly 33 can be stably erected on the ground. When the support assembly 33 is in the folded state, the occupied space of the support assembly 33 is greatly reduced, thereby facilitating carrying.

[0077] Specifically, the support assembly 33 comprises a sliding block 331, a support leg 332, and a connecting piece 333. The sliding block 331 is slidingly connected to the telescopic assembly 31, one end of the support leg 332 is rotatably connected to the sliding block 331, one end of the connecting piece 333 is fixed to the bottom of the telescopic assembly 31, and the other end of the connecting piece 333 is connected to the support leg 332. When the sliding block 331 is driven to move along the telescopic assembly 31 and the sliding block 331 moves away from the fan head assembly 10, the support leg 332 moves towards the radial direction of the telescopic assembly 31, thereby achieving the unfolded state. When the sliding block 331 is driven to move along the telescopic assembly 31 and the sliding block 331 moves towards the fan head assembly 10, the support leg 332 moves towards the telescopic assembly 31, thereby achieving the folded state. When the support assembly 33 is in the folded state, the occupied space of the fan 100 can be greatly reduced, thereby facilitating the user to carry the fan outdoors and further improving the user experience. In addition, the support assembly 33 further comprises a first blocking piece and a second blocking piece. The first blocking piece and the second blocking piece are arranged at intervals on the telescopic assembly 31, and the sliding block 331 is arranged between the first blocking piece and the second blocking piece, so that the first blocking piece and the second blocking piece form a predetermined stroke interval, and the sliding block 331 slides in the predetermined stroke interval, thereby avoiding that the support leg 332 is unfolded too much or folded too much relative to the telescopic assembly 31.

[0078] Optionally, the number of support legs 332 is three, and the three support legs 332 are arranged at intervals along the circumferential direction of the sliding block 331. In the outdoor environment, three foot points that are relatively on the same horizontal plane and can be used when the support assembly 33 is in the unfolded state are needed, and the space enclosed by the three support legs 332 allows to be uneven, or the space outside the three support legs 332 can also be uneven, and compared with a flat base, it is more suitable for complex outdoor environments. In this application, the number of support legs 332 is not limited, and the number of support legs 332 can be four or five.

[0079] Optionally, the bottom of the support leg 332 is provided with an anti-skid piece 334 to prevent the support leg 332 from sliding on a smooth ground.

[0080] The inner side wall of the support leg 332 is provided with a relief groove corresponding to the position of the connecting piece 333, and the connecting piece 333 is fixedly installed on the relief groove.

[0081] In some embodiments, the support mechanism 30 further comprises a reinforcing piece 34 for limiting the end of the support leg 332 away from the sliding block 331 relative to the ground when the support assembly 33 is in the unfolded state, so as to prevent the support leg 332 from moving.

[0082] Optionally, the reinforcing member 34 is in a needle structure. The reinforcing member 34 is pivotally connected to the support leg 332 at an end away from the sliding block 331, and the support leg 332 is provided with a receiving groove, and the reinforcing member 34 can be accommodated in the receiving groove. When it is necessary to reinforce the stability of the support assembly 33, the reinforcing member 34 is manually extended from the receiving groove, so that the reinforcing member 34 is perpendicular to the ground, and then the reinforcing member 34 is pressed by an external force, and the reinforcing member 34 is further inserted into the ground, thereby improving the stability of the support assembly 33. In addition, in order to solve the problem that the reinforcing member 34 slides out of the receiving groove due to its own gravity, a locking structure is usually added, for example, a limiting protrusion is usually added in the receiving groove, so that part of the reinforcing member 34 elastically interferes with the receiving groove, thereby further achieving the limiting effect. In addition, the support leg 332 is provided with a limiting portion for limiting the movement of the reinforcing member 34, so that when the reinforcing member 34 is manually extended from the receiving groove, the reinforcing member 34 is kept perpendicular to the ground.

[0083] Optionally, the end of the support leg 332 away from the sliding block 331 is provided with a socket 332a for inserting the reinforcing member 34, so that the reinforcing member 34 is inserted into the ground to limit the movement of the support leg 332. Specifically, the reinforcing member 34 includes a constraint portion 341 and a needle portion 342, and the constraint portion 341 is fixedly connected with the needle portion 342. When the reinforcing member 34 is inserted into the ground through the socket 332a, at least part of the needle portion 342 is inserted into the ground, and the constraint portion 341 limits the movement of the support leg 332 away from the ground, so that the ground and the constraint portion 341 jointly clamp the support leg 332.

[0084] In some embodiments, the support mechanism 30 further includes a limiting structure 35 for restraining the support leg 332 in the telescopic assembly 31 when the support assembly 33 is in the folded state, thereby reducing the risk that the limiting structure 35 causes the support assembly 33 to change from the folded state to the unfolded state under the conditions of transportation, its own gravity and vibration.

[0085] Please refer to Figure 15 Optionally, the limiting structure 35 includes two elastic arms 351 and a clamping portion 352. The two elastic arms 351 are arranged in one of the two adjacent support legs 332, and the support leg 332 and the two elastic arms 351 jointly enclose a clamping groove 335a, and the clamping portion 352 is arranged in the other support leg 332, and the two support legs 332 are arranged opposite to the clamping portion 352. When the support assembly 33 changes from the unfolded state to the folded state, the clamping portion 352 is inserted into the clamping groove 335a, and the two elastic arms 351 jointly clamp the clamping portion 352, thereby preventing the support assembly 33 from changing from the folded state to the unfolded state under the non-human force state. It should be noted that the non-human force state refers to the conditions of its own gravity or vibration caused by transportation.

[0086] Optionally, the support leg 332 is provided with a clamping groove 335a, and the telescopic assembly 31 is provided with a clamping portion 352, which is used to insert into the clamping groove 335a when the support leg 332 is folded on the telescopic assembly 31, so that the support leg 332 is locked relative to the telescopic assembly 31.

[0087] Please refer to Figure 16 and Figure 17 The limiting structure 35 includes a clamping groove 335b, a clamping portion 354, a pressing piece 355 and an elastic piece 356. The pressing piece 355 is slidingly connected to the telescopic assembly 31, one end of the elastic piece 356 is connected to the pressing piece 355, and the other end of the elastic piece 356 is connected to the telescopic assembly 31. The pressing piece 355 keeps a tendency to move away from the telescopic assembly 31 under the elastic force of the elastic piece 356; the clamping portion 354 is arranged on the pressing piece 355, and the clamping groove 335b is arranged on the support leg 332. When the support assembly 33 changes from the unfolded state to the folded state, the clamping portion 354 is clamped into the clamping groove 335b, and the clamping portion 354 abuts against the clamping groove 335b in a direction away from the telescopic assembly 31, so that the support leg 332 is limited relative to the telescopic assembly 31, achieving the effect of restricting the support leg 332. When the user needs to change the support assembly 33 from the folded state to the unfolded state, the pressing piece 355 is pressed downward, so that the pressing piece 355 moves towards the telescopic assembly 31, and the clamping portion 354 is separated from the clamping groove 335b, so that the support leg 332 is unlocked relative to the telescopic assembly 31.

[0089] When using the fan 100, first, press the pressing piece 335, so that the supporting feet 332 and the pressing piece 335 are separated from each other, slide the slider 331 towards the direction of the energy storage assembly 20, then the supporting feet 332 are expanded towards the radial direction of the telescopic assembly 31, and the supporting feet 332 and the telescopic assembly 31 form a stable triangular structure, at the same time, the needle part 342 of the reinforcing piece 34 is inserted into the ground, at this time, the supporting feet 332 can be placed on the ground, then, rotate the handle part 3213 or the nut 326, so that the elastic pad 322 or the clamping sleeve 324 press tightly or loosen the second rod 312, thereby adjusting the height of the telescopic assembly 31 as a whole, then, according to the requirement, change the wind direction of the fan 100 in the first direction R1 or the second direction R2, when the fan 100 needs to rotate in the first direction R1, press the button in the remote controller 40, at this time, the bracket 11 rotates in the first direction R1 relative to the energy storage assembly 20, when the fan 100 needs to rotate in the second direction R2, press the button in the remote controller 40, at this time, the fan 12 rotates in the second direction R2 relative to the bracket 11.

[0090] Alternatively, first, separate the telescopic assembly 31 from the energy storage assembly 20 by rotating the supporting mechanism 30, then place the energy storage assembly 20 on the desktop 300, or hang the fan 100 by using the hook 26; then according to the requirement, press the button of the remote controller 40, adjust the rotating angle of the fan in the first direction R1 and the second direction R2, or rotate the fan 12 by hand, change the position of the fan 12 in the second direction R2 and stop applying external force, so that the fan 100 is fixed in a specific position for blowing.

When energy storage subassembly 20 and support mechanism 30 are the connecting state, support mechanism 30 lifts fan head subassembly 10 to the preset height, that is, the height of fan head subassembly 10 relative to the ground or desktop, to meet the height requirement of user, and support mechanism 30 can form second base, second base can be directly placed on the ground or desktop, to provide support for fan 100.
