DETAILED DESCRIPTION

[0041] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0042] Reference below Figure 1-Figure 10 The fan 100 according to an embodiment of the present invention is described. The embodiment of the present invention can realize two locking or disassembly through one action, one is the locking or disassembly of the fan head 1 and the motor base 2, and the other is the locking or disassembly of the first mesh cover 11 and the second mesh cover 12. The disassembly connection is fast and convenient.

[0043] like Figure 1-Figure 10 As shown, a fan 100 according to an embodiment of the present invention includes: a motor base 2, a fan head 1 and a locking structure.

[0044] Among them, the motor base 2 is provided with a pressing portion 22; the fan head 1 includes a first mesh cover 11 and a second mesh cover 12 that are detachably connected; the locking structure includes a push rod 111, which is movably installed on the first mesh cover 11, and the second mesh cover 12 is provided with a limiting portion. When the first mesh cover 11 is connected to the motor base 2, the pressing portion 22 pushes the push rod 111 and the limiting portion to be locked.

[0045] In practice, refer to Figure 1 and Figure 2 As shown, the fan head 1 can be rotationally connected to the motor base 2, and can also be axially plugged in. Generally, when the motor base 2 and the fan head 1 are circumferentially connected, the pressing portion 22 provided on the inner circumference of the motor base 2 presses the top rod 111. When the fan head 1 and the motor base 2 need to be disassembled, the fan head 1 and the motor base 2 are disassembled first, and the pressing portion 22 is also disengaged from the top rod 111 at this time, and then the fan head 1 disassembles the first mesh cover 11 and the second mesh cover 12.

[0046] Specifically, a radially arranged and movable push rod 111 may be provided on the side of the first mesh cover 11 away from the motor base 2, and the push rod 111 may move radially relative to the first mesh cover 11. At the same time, a limiting portion is provided on the side of the second mesh cover 12 close to the first mesh cover 11, and the limiting portion is provided with a limiting hole. The limiting hole of the limiting portion may be radially opposite to the position where the push rod 111 is set. When the push rod 111 moves radially, it may be more accurately inserted into or out of the limiting hole, so that the push rod 111 can be connected to the second mesh cover 12 through the limiting portion, and the second mesh cover 12 is prevented from circumferential displacement. It should be noted that the push rod is only for transmission, and is not necessarily a straight strip, but may also be an arc-shaped structure.

[0047] Of course, as another embodiment of the present invention, the top rod 111 can also be arranged radially on the first mesh cover 11 but move along the circumferential direction to lock the second mesh cover 12. At this time, the structure and position of the pressing portion 22 inside the motor base 2 are changed, so that the pressing portion 22 pushes the side movement of the top rod 111, and the top rod 111 and the limiting portion of the second mesh cover 12 are arranged in a bent structure, and the bent structure is consistent with the circumferential direction of the second mesh cover 12. The limiting portion is also arranged in the circumference of the second mesh cover 12, which can limit the circumferential position of the top rod 111 and leave a certain amount of space for the top rod 111 in the circumferential direction of the first mesh cover 11. The movement space of the push rod 111 can be set radially to prevent the push rod 111 from moving radially. The movement of the push rod 111 at this time is different from the radial movement of the push rod 111 mentioned above. When the pressing portion 22 presses against the push rod 111 at the side, the push rod 111 is pushed to move circumferentially along the first mesh cover 11. When the push rod 111 moves circumferentially, the bent structure of the push rod 111 is connected to the limiting portion of the second mesh cover 12, that is, the side surface of one end of the push rod 111 is pressed by the pressing portion 22, and the other end is inserted into the limiting hole in the second mesh cover 12 along the circumferential direction, which can also complete the connection between the first mesh cover 11 and the second mesh cover 12.

[0048] The embodiment of the present invention can realize two locking or disassembly by one action, one is the locking or disassembly of the fan head 1 and the motor base 2, and the other is the locking or disassembly of the first mesh cover 11 and the second mesh cover 12.

[0049] It should be noted that the installation requirements of the prior art require the use of screws to improve user safety. The technology of the embodiment of the present invention will unlock during the process of assembling / disassembling the fan head, and the screw solution can be omitted, but it does not rule out the use of screws to lock other parts of this solution.

[0050] In some embodiments, the locking structure further includes an elastic member 113 , which is connected between the top rod 111 and the first mesh cover 11 , and is used to apply an elastic force to the top rod 111 away from the limiting portion.

[0051] Combination Figure 2 and Figure 4 As shown, when the top rod 111 is arranged in the radial direction of the first mesh cover 11 and can move in the radial direction, the elastic member 113 of the embodiment of the present invention can be a spring, and the spring is arranged between the top rod 111 and the first mesh cover 11, as shown in FIG. Figure 2 In the embodiment, a spring can be arranged at the rear of the top rod 111 and one end of the spring is connected to the top rod 111 and the other end is connected to the first mesh cover 11. When the top rod 111 moves, the spring will also be deformed. For example, when the top rod 111 moves radially away from the center of the first mesh cover 11, the spring is compressed. At this time, the bottom of the top rod 111 and the pressing portion 22 in the motor base 2 are in a pressing state, so that even if the spring is compressed, it will not affect the radial movement of the top rod 111.

[0052] When the motor base 2 and the fan head 1 are disassembled, the pressing portion 22 in the motor base 2 begins to separate from the position where the push rod 111 is pressed against. At this time, the push rod 111 will be pushed to return to its original state under the action of the elastic member 113, so that the limiting portion of the second mesh cover 12 is disengaged from the push rod 111 on the first mesh cover 11. At this time, the first mesh cover 11 and the second mesh cover 12 can be disassembled.

[0053] In some embodiments, the top rod 111 is movable along the radial direction of the first mesh cover 11 , the limiting portion is provided at the edge of the second mesh cover 12 , one end of the top rod 111 is adapted to be limitedly matched with the limiting portion, and the pressing portion 22 is adapted to push the other end of the top rod 111 .

[0054] Through the above scheme, the push rod 111 is set in the radial direction of the first mesh cover 11 and moves along the radial direction. When the pressing part 22 inside the motor base 2 presses the inner end of the push rod 111, the push rod 111 is more convenient to move and can move along a predetermined motion trajectory, and the movement is smoother.

[0055] Among them, the top rod 111 is arranged in the radial direction of the first mesh cover 11 and can move radially. When the top rod 111 is in a natural state, the top rod 111 leaves space at the edge of the first mesh cover 11. At this time, the second mesh cover 12 and the first mesh cover 11 can be simply connected through the internal structure, and then the limiting part of the second mesh cover 12 is provided with a limiting hole along the radial direction. The limiting hole is aligned with the end of the top rod 111. When the top rod 111 moves radially toward a position away from the center of the first mesh cover 11, it is inserted into the limiting part of the second mesh cover 12, so that the first mesh cover 11 and the second mesh cover 12 are connected to prevent the second mesh cover 12 from moving circumferentially.

[0056] In some embodiments, the top rod 111 includes a first top rod segment 1111, an arcuate transition segment 1112 and a second top rod segment 1113, the arcuate transition segment 1112 is connected between the first top rod segment 1111 and the second top rod segment 1113, the first top rod segment 1111 extends radially along the first mesh cover 11 to cooperate with the limiting portion, and the second top rod segment 1113 extends axially along the first mesh cover 11 to cooperate with the pressing portion 22.

[0057] Reference Figure 6 As shown, the first top rod section 1111, the arc-shaped transition section 1112 and the second top rod section 1113 of the top rod 111 are an integrally formed structure, and the top rod 111 as a whole is a plate-shaped structure. During actual connection, the first top rod section 1111 is mainly connected along the inner radial direction of the first mesh cover 11, and the arc-shaped transition section 1112 gradually approaches one side of the motor base 2 along one end of the first top rod section 1111, and the second top rod section 1113 is arranged axially along the motor base 2 and the first mesh cover 11. When the motor base 2 and the fan head 1 are in a connected state, the second top rod section 1113 is in contact with the pressing portion 22, and the pressing portion 22 limits the second top rod section 1113, so that the second top rod section 1113 will not detach when the motor base 2 and the fan head 1 are normally installed. At the same time, the end of the first top rod section 1111 extends into the limiting portion of the second mesh cover 12, completing the connection between the top rod 111 and the second mesh cover 12.

[0058] The embodiment of the present invention sets the top rod 111 into three sections with different shapes, so that the top rod 111 can be connected to the inside of the first mesh cover 11, and can also make the top rod 111 contact with the pressing part 22 inside the motor base 2, and the pressure applied to the second top rod section 1113 by the pressing part 22 maintains the connection between the top rod 111 and the second mesh cover 12.

[0059] In some embodiments, the first top rod section 1111 is located on a side of the first mesh cover 11 close to the second mesh cover 12 , and the end of the second top rod section 1113 extends to a side of the first mesh cover 11 away from the second mesh cover 12 to extend toward the motor base 2 .

[0060] In actual design, the top rod 111 can be set on the side of the first mesh cover 11 away from the second mesh cover 12, and the structural design of the top rod 111 is the same as the above-mentioned structural design. At this time, when the first mesh cover 11 is connected to the motor base 2, one end of the first mesh cover 11 connected to the motor base 2 is rotated inside the motor base 2, so that the top rod 111 located outside the first mesh cover 11 contacts the pressing part 22 inside the motor base 2. Generally, the pressing part 22 is set inside the motor base 2, which can protect the pressing part 22 and ensure the neatness and comfort of the appearance of the motor base 2. In the embodiment of the present invention, the top rod 111 is set inside the first mesh cover 11, that is, the top rod 111 is set on the side of the first mesh cover 11 away from the motor base 2. This is also to maintain the neatness of the outside of the fan 100, and to prevent the top rod 111 from being located outside and easily damaged by accident.

[0061] Therefore, the above-mentioned first top rod section 1111 is located on the side of the first mesh cover 11 close to the second mesh cover 12, and the end of the second top rod section 1113 extends to the side of the first mesh cover 11 away from the second mesh cover 12 to extend toward the motor base 2. When the motor base 2 is connected to the fan head 1, it is convenient to facilitate the pressure between the second top rod section 1113 and the pressing part 22 inside the motor base 2 while maintaining the neatness of the outside of the first mesh cover 11.

[0062] In some embodiments, the first mesh cover 11 is provided with a limit block 112, the limit block 112 is formed with a sliding groove penetrating along the radial direction of the first mesh cover 11, and the first push rod section 1111 is slidably arranged in the sliding groove.

[0063] Reference Figure 2 As shown, multiple limit blocks 112 can be set in the radial direction of the first mesh cover 11, or one can be set. When multiple limit blocks 112 are set, the multiple limit blocks 112 are distributed at intervals along the radial direction. When there is only one limit block 112, the limit block 112 can be extended along the radial direction of the first mesh cover 11. By setting the limit block 112, the top rod 111 can always move repeatedly along the same radial direction of the first mesh cover 11 when subjected to thrust, thereby ensuring the running trajectory of the top rod 111, so that one end of the top rod 111 can be accurately pressed by the pressing part 22 of the motor base 2, and the other end can also be accurately connected to the limiting part of the second mesh cover 12.

[0064] In some embodiments, there are multiple limit blocks 112, and the multiple limit blocks 112 are spaced apart and distributed along the radial direction of the first mesh cover 11. When the limit blocks 112 are set to be multiple, the multiple limit blocks 112 are spaced apart and distributed along the radial direction of the first mesh cover 11, and at least one limit block 112 is set at a position close to the edge of the first mesh cover 11, and a space for connecting the second mesh cover 12 is reserved at the edge position, and the first top rod segment 1111 of the top rod 111 penetrates into the multiple limit blocks 112, and the multiple limit blocks 112 limit the first top rod segment 1111 circumferentially. Setting multiple smaller limit blocks 112 can save materials and is convenient to set up, and can limit at different positions of the first top rod segment 1111 to maintain the stability of the running path of the first top rod segment 1111.

[0065] In some embodiments, the second top rod section 1113 is suitable for extending into the motor base 2; or, the motor base 2 is plug-connected to the fan head 1 and defines a plug-in space, the pressing portion 22 is located in the plug-in space, and the second top rod section 1113 is suitable for extending into the plug-in space to abut against the pressing portion 22.

[0066] In practice, the second top rod section 1113 bends along the arc-shaped transition section toward one side of the motor base 2, and extends into the motor base 2, close to the pressing portion 22, and abuts against the pressing portion 22 when locked, and disengages from the pressing portion 22 when released, so that the second top rod section 1113 can smoothly enter the interior of the motor base 2 through the plug-in space; moreover, when the fan head 1 and the motor base 2 are assembled, the top rod 111 that cooperates with the pressing portion 22 of the motor base 2 is hidden in the motor base 2, or is hidden in the plug-in space formed by the motor base 2 and the first mesh cover 11, so that the user cannot operate it.

[0067] In some embodiments, the top rod 111 is provided with a first limit plate 115, the first mesh cover 11 is provided with a second limit plate 114, an installation space is formed between the first limit plate 115 and the second limit plate 114, and the elastic member 113 is located in the installation space and its two ends are respectively pressed against the first limit plate 115 and the second limit plate 114.

[0068] Reference Figure 4 and Figure 6As shown, the first limiting plate 115 is perpendicular to the first top rod section 1111, and the second limiting plate 114 is also perpendicular to the first mesh cover 11. The elastic member 113 is consistent with the direction of the first top rod section 1111. The elastic member 113 is connected to the first top rod section 1111 and is arranged between the first limiting plate 115 and the second limiting plate 114. When the top rod 111 is arranged inside the sliding groove formed in the above-mentioned limiting block 112, the elastic member 113 is arranged at a position above the first limiting plate 115, and the other end of the elastic member 113 is also connected to the second limiting plate 114. When the top rod 111 is pressed by the pressing portion 22 and pushed in a direction away from the center of the first mesh cover 11, the elastic member 113 is compressed. When the bottom of the top rod 111 is separated from the pressing portion 22, the top rod 111 is pushed toward the center of the first mesh cover 11 under the action of the elastic member 113, so that the top rod 111 is separated from the limiting portion of the second mesh cover 12.

[0069] In the embodiment of the present invention, the first limiting plate 115 and the second limiting plate 114 are provided to enable the elastic member 113 to undergo elastic changes, thereby driving the movement of the push rod 111 and ensuring the stability of the movement of the push rod 111 .

[0070] In some embodiments, the pressing portion 22 is formed with a pressing groove 221 , and at least a portion of the push rod 111 extends into the pressing groove 221 . An arc-shaped pressing surface is formed in the pressing groove 221 , and the arc-shaped pressing surface is used to push the push rod 111 to move.

[0071] Reference Figure 8 As shown, the opening of the pressing groove 221 is toward the inner wall direction of the motor base 2, and the pressing groove 221 includes an arc-shaped pressing surface, wherein the curvature of the arc-shaped pressing surface is arranged along the circumference of the motor base 2. When the fan head 1 and the motor base 2 are relatively connected, and the arc-shaped pressing surface begins to press the top rod 111, the second top rod segment 1113 of the top rod 111 advances along the curvature direction of the arc-shaped pressing surface until the fan head 1 and the motor base 2 are locked. At this time, the second top rod segment 1113 of the top rod 111 is just pressed against the inside of the pressing groove 221, so that the second top rod segment 1113 is limited and also remains in a stationary state, and the end of the first top rod segment 1111 of the top rod 111 also penetrates into the limiting portion of the second mesh cover 12. At this time, the first mesh cover 11 and the second mesh cover 12 are in a reliably connected state, and the motor base 2 and the fan head 1 are also in a connected state.

[0072] In some embodiments, the pressing portion 22 includes a pressing section 222 and a connecting section 223, the pressing section 222 and the connecting section 223 are connected to form a pressing groove 221 open on one side, at least a portion of the push rod 111 is suitable for extending from the open side of the pressing groove 221 into the pressing groove 221, and the arc-shaped pressing surface is provided on the pressing section 222.

[0073] Continue to refer to Figure 8 As shown, the edge of the pressing section 222 is an arc-shaped pressing surface, which can ensure that the second push rod section 1113 of the push rod 111 gradually enters the pressing groove 221 along the arc-shaped pressing surface. At this time, the fan head 1 is also connected to the motor base 2. The connecting section 223 and the pressing section 222 have an angle, and the connecting section 223 can be configured to be connected to the inner wall of the motor base 2. The pressing section 222 can include an arc-shaped pressing surface and an oblique clamping surface. The oblique clamping surface and the arc-shaped pressing surface together constitute the pressing section 222. The arc-shaped pressing surface is located at the edge of the pressing section 222. The oblique clamping surface is directly connected to the connecting section 223 to form the pressing groove 221.

[0074] In practice, when at least a portion of the push rod 111 contacts the pressing section 222, the push rod 111 can be pushed radially in the direction away from the center of the first mesh cover 11. That is to say, when at least a portion of the push rod 111 contacts the pressing section 222, the connection at the edge of the first mesh cover 11 and the second mesh cover 12 can be achieved, but the push rod 111 has not yet completely entered the pressing groove 221 or has not yet been limited to a certain extent. The embodiment of the present invention arranges the pressing section 222 into such a structure that the second push rod section 1113 of the push rod 111 enters the oblique clamping surface smoothly along with the arc-shaped pressing surface, so that it can be limited in the pressing groove 221 formed by the oblique clamping surface and the connecting section 223, and the second push rod section 1113 is not easy to loosen or detach from the pressing portion 22.

[0075] In some embodiments, the motor base 2 is rotatably connected to the fan head 1 , and the pressing portion 22 presses against the top rod 111 when the fan head 1 rotates relative to the motor base 2 .

[0076] In practice, the fan head 1 includes a first mesh cover 11 and a second mesh cover 12 and fan blade components therein. The fan blade components can be preliminarily and simply connected to the first mesh cover 11 and the second mesh cover 12, and then the fan head 1 can be rotated relative to the motor base 2 as a whole. During the rotation, the bottom of the top rod 111 of the first mesh cover 11 just rotates to the pressing portion 22 inside the motor base 2, so that the pressing portion 22 presses the top rod 111 to move, thereby pushing the top rod 111 toward a position away from the center of the first mesh cover 11 to lock the second mesh cover 12.

[0077] The fan head 1 is rotated relative to the motor base 2 to facilitate the connection between the fan head 1 and the motor base 2. When the motor base 2 rotates relative to the fan head 1, the top rod 111 of the fan head 1 gradually presses against the pressing part 22 inside the motor base 2, thereby connecting the first mesh cover 11 and the second mesh cover 12 of the fan head 1 itself.

[0078] In some embodiments, the motor base 2 is provided with a first screw-on portion 21, and the fan head 1 is provided with a second screw-on portion 118. The first screw-on portion 21 and the second screw-on portion 118 are both staggered with the locking structure. One of the first screw-on portion 21 and the second screw-on portion 118 is provided with a limiting protrusion 117 and the other is provided with a limiting recess 23. The limiting protrusion 117 is suitable for being snapped into the limiting recess 23 when the first screw-on portion 21 and the second screw-on portion 118 are screwed to a set position.

[0079] In practice, the first screw-on portion 21 is an axial extension of the motor base 2, and the second screw-on portion 118 is an axial extension along the connecting hole 116 of the first mesh cover 11, and the diameter of the second screw-on portion 118 can be set smaller than the diameter of the first screw-on portion 21. The second screw-on portion 118 is inserted into the first screw-on portion 21, and the inner wall of the second screw-on portion 118 can be provided with a plurality of spaced-apart limiting protrusions 117, and the inner wall of the first screw-on portion 21 is provided with a plurality of spaced-apart limiting recesses 23 corresponding to the positions of the limiting protrusions 117.

[0080] When the fan head 1 rotates relative to the motor base 2, the limiting protrusion 117 of the second screw-on part 118 is inserted into the limiting recess 23 on the inner wall of the first screw-on part 21, so that the fan head 1 is clamped between the motor base 2, and then a tightening thread can be provided on the inner edge of the first screw-on part 21, and a small number of threads are also provided on the outside of the second screw-on part 118 at a position in contact with the edge of the first screw-on part 21, so that the first screw-on part 21 and the motor base 2 are rotationally connected through the second screw-on part 118 through a small number of threads, and are clamped through the limiting protrusion 117 and the limiting recess 23, thereby enhancing the reliability of the connection between the fan head 1 and the motor base 2.

[0081] In some embodiments, the fan head 1 includes fan blades 4, which include a connecting shaft 5 and fan blades. The fan blades are located inside the fan head 1 and are sleeved outside the connecting shaft 5. The two ends of the connecting shaft 5 are rotatably supported on the first mesh cover 11 and the second mesh cover 12 through bearing structures, respectively, and the connecting shaft 5 is dynamically connected to the driving member of the motor base 2.

[0082] Among them, one end of the connecting shaft 5 is used for power connection with the driving member of the motor base 2, and the other end is connected to the side of the second mesh cover 12 close to the first mesh cover 11. A wind is sleeved on the connecting shaft 5. The fan blade includes a plurality of fan blade units and a fan blade sleeve. The plurality of fan blade units are connected and arranged around the fan blade sleeve. The fan blade sleeve is provided with a mounting hole. A connecting sleeve 7 can be arranged inside the mounting hole. The middle part of the connecting sleeve 7 is arranged as a disc-shaped structure arranged along the radial direction of the fan blade sleeve. The periphery of the disc-shaped structure is connected to the inner wall of the fan blade sleeve as a whole, and connecting parts are provided at both axial ends of the disc-shaped structure. The connecting part is provided with an internal thread. The connecting shaft 5 passes through the connecting sleeve 7 and is threadedly connected to the connecting part of the connecting sleeve 7, so that the connecting shaft 5 is connected to the fan blade. After the connecting shaft 5 is connected to the driving member, the driving member rotates and drives the connecting shaft 5 to rotate, thereby driving the fan blade to rotate.

[0083] At this time, the connecting shaft 5 and the first mesh cover 11 and the second mesh cover 12 can be rotatably connected through a bearing structure to ensure that the fan blades are rotatably connected relative to the first mesh cover 11 and the second mesh cover 12. In addition, it should be noted that a locking nut can be provided on the side of the connecting shaft 5 close to the second mesh cover 12 to prevent the fan blades from moving axially on the connecting shaft 5.

[0084] In some embodiments, a driving member is provided in the motor base 2, and a fan blade 4 is provided in the fan head 1, and the fan blade 4 is dynamically connected to the driving member.

[0085] Specifically, the connecting shaft 5 of the fan blade 4 can be connected to a driving member, and the driving member can be a driving shaft of a motor, so that the motor inside the motor base 2 can drive the connecting shaft 5 to rotate during rotation, thereby driving the fan blade to rotate.

[0086] In addition, the fan head 1 is provided with an air outlet, and the fan blades 4 are constructed as axial flow blades, which are suitable for driving the airflow in the fan head 1 to flow toward the air outlet along the axial direction of the axial flow blades.

[0087] The axial flow blades are suitable for driving the airflow in the fan head 1 to flow toward the air outlet along the axial direction of the axial flow blades. That is to say, the blades 4 of the fan 100 of the present invention are different from the conventional centrifugal blades 4, and can realize axial air intake and axial air outlet, wherein, during actual operation, the axial flow blades rotate and drive the airflow at the rear side of the axial flow blades to flow forward along the axial direction thereof, and then flow to the air outlet at the front of the fan head 1 and transport toward the user's face.

[0088] Among them, it should be noted that the fan head 1 can be provided with an air inlet, and the air inlet can be provided on the rear side of the fan head 1 for axial air inlet, or can be provided on the circumferential outer side of the fan head 1 for oblique air inlet, both of which can realize the air inlet function of the fan head 1, and the airflow entering the fan head 1 can flow to the axial rear end of the axial flow fan blade, and then flow forward axially to the air outlet under the action of the axial flow fan blade. In particular, an air inlet can be provided on the rear side of the fan head 1, and a heat dissipation channel is provided in the motor base 2, so that the heat dissipation channel is connected with the air inlet, and then under the driving action of the axial flow fan blade, the airflow is driven to dissipate the heat for the driving parts and the like in the heat dissipation flow, and then flows from the air inlet to the user, which is not only beneficial to air supply, but also can realize the internal heat dissipation of the motor base 2.

[0089] In some embodiments, the radial dimension of the fan head 1 is greater than or equal to twice the radial dimension of the motor base 2 at the location of the driving member, and / or the ratio of the radial dimension to the axial dimension of the fan head 1 is greater than or equal to 1. Therefore, the fan 100 in the present invention is different from the traditional crossflow impeller. It should be noted that the traditional tower fan uses a crossflow impeller, and the radial dimension of the tower fan at various positions in the axial direction does not change significantly, while the radial dimension of the fan head 1 in the present invention is much larger than the radial dimension of the motor base 2 at the driving member.

[0090] At the same time, compared with centrifugal fan blades, the provision of axial flow fan blades is conducive to more stable placement of the fan head 1 and the motor base 2, thereby ensuring the stability of the position state of the fan 100.

[0091] In some embodiments, the fan head 1 as a whole is independently disassembled relative to the motor base 2. In practice, the first mesh cover 11 of the fan head 1 cooperates with the motor base 2 to form a structure in which the fan head 1 can be independently arranged and disassembled.

[0092] And / or, the fan head 1 is suitable for being connected to the motor base 2 along a first direction in the initial position, the first direction intersecting the vertical direction, and the fan head is configured to be able to swing up and down and / or left and right relative to the motor base from the initial position.

[0093] That is to say, when the fan head 1 is in the initial position relative to the motor base 2, the fan head 1 can be moved along a first direction relative to the motor base 2, so that the fan head 1 is connected and fixed to the motor base 2. If the first direction is along the horizontal direction, the fan head 1 can be installed at the front end of the motor base 2 from front to back along the horizontal direction, so as to realize the connection and fixation of the two along the horizontal direction.

[0094] The first direction may also form a certain inclination angle relative to the horizontal direction and intersect with the vertical direction, that is, the first direction may be inclined upward or downward relative to the horizontal direction, so that the installation of the fan head 1 is more flexible.

[0095] That is to say, the fan head 1 is configured to be able to swing up and down and / or left and right relative to the motor base from an initial position, that is, after the fan head 1 is connected and fixed to the motor base 2, the user can further adjust the angle of the fan head 1. For example, the fan head 1 and the motor base 2 are installed together on the base 3, and the fan head 1 can be driven to adjust in different directions such as up, down, left and right relative to the base 3. At this time, the fan head 1 can be adjusted until its axis is parallel to the vertical direction, so that the adjustment range of the fan head 1 is larger, thereby meeting the user's air supply needs in more directions.

[0096] In some embodiments, a base 3 is further included, and the base 3 is suitable for being supported on a placement surface, and the motor base 2 is installed on the base 3 .

[0097] Reference Figure 1 As shown, for the floor-standing fan 100, the base 3 can be set higher, the base 3 can be set higher, it can also be set to a desktop type, or it can be set to a wall-mounted type. If the base 3 is set on the ground or on the desktop, the bottom of the base 3 is generally provided with a disc for forming a support with the ground or the desktop, and the end of the base 3 away from the ground is provided with a motor base 2, and the motor base 2 is then installed with the fan head 1, and the base 3 is used to support the motor base 2 and the fan head 1. When the fan 100 is working or not working, the base 3 is supported on the placement surface, which can make the placement of the fan 100 more stable. The fan 100 can be supported on the placement surface by the base 3, that is, the fan 100 can be placed on the ground. This kind of floor fan is conducive to the overall stable placement of the fan 100, or the overall height of the fan 100 can be flexibly adjusted by the base 3 of different heights, which is conducive to being suitable for different types of application scenarios and meeting different types of user usage needs.

[0098] The embodiment of the present invention further discloses a fan assembly method, which is applicable to the fan 100 described above. Fig.11 As shown, the assembly method includes:

[0099] S1: buckle the first mesh cover 11 and the second mesh cover 12;

[0100] S2: Connect the first mesh cover 11 to the motor base 2 and enable the motor base 2 to push the top rod 111 on the first mesh cover 11 to move until it is locked with the second mesh cover 12.

[0101] In practice, the first mesh cover 11 and the second mesh cover 12 and their internal structures are first connected and buckled, and then the overall structure of the first mesh cover 11 and the second mesh cover 12 is rotated so that the top rod 111 of the first mesh cover 11 is pressed against the pressing part inside the motor base 2, and the top rod 111 is moved to lock with the second mesh cover 12. This connection method will unlock the fan head 1 during the assembly or disassembly process, and the screw solution can be omitted.

[0102] According to the fan assembly method of the embodiment of the present invention, the first mesh cover 11 is connected to the motor base 2 and the motor base 2 pushes the top rod 111 on the first mesh cover 11 to move to lock with the second mesh cover 12, which includes: rotating the first mesh cover 11 and the second mesh cover 12 as a whole relative to the motor base 2. During the relative rotation, the pressing portion 22 of the motor base 2 pushes the top rod 111 to move radially along the first mesh cover 11 to lock with the limiting portion of the second mesh cover 12.

[0103] That is to say, when the first mesh cover 11 and the second mesh cover 12 are connected to the motor base 2, they are mainly connected, and after the first mesh cover 11 and the motor base 2 are connected, the push rod 111 is pushed by the pressing part 22 so that the push rod 111 is connected to the limiting part of the second mesh cover 12. At this time, the first mesh cover 11 and the second mesh cover 12 are locked. The embodiment of the present invention is easy to install and disassemble, and saves installation time.
