DETAILED DESCRIPTION

[0041] Embodiments of the present application are described below in detail, examples of which are shown in the drawings, wherein the same or similar reference signs represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present application, and cannot be understood as a limitation of the present application.

[0042] Reference is made below to Figures 1-10 The fan 100 according to the embodiments of the present application is described, which can realize two locking or dismounting through one action, one is the locking or dismounting of the fan head 1 and the motor base 2, and the other is the locking or dismounting of the first mesh cover 11 and the second mesh cover 12, which is fast and convenient.

[0043] As Figures 1-10 shown, the fan 100 according to the embodiments of the present application comprises the motor base 2, the fan head 1 and the locking structure.

[0044] The motor base 2 is provided with the pressing part 22; the fan head 1 comprises the first mesh cover 11 and the second mesh cover 12 which are detachably connected; the locking structure comprises the top rod 111 which is movably mounted on the first mesh cover 11, and the second mesh cover 12 is provided with the limiting part, and when the first mesh cover 11 is connected with the motor base 2, the pressing part 22 pushes the top rod 111 and the limiting part to limit and lock.

[0045] In practice, referring to Figure 1 and Figure 2 shown, the fan head 1 can be rotationally connected with the motor base 2, or can be axially inserted, and generally in the case of circumferential connection of the motor base 2 and the fan head 1, the pressing part 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 dismounted, the fan head 1 and the motor base 2 are first dismounted, at this time the pressing part 22 is also disengaged from the top rod 111, and then the fan head 1 dismounts the first mesh cover 11 and the second mesh cover 12.

[0046] Specifically, the first mesh cover 11 can be provided with a movable top rod 111 arranged in the radial direction and away from the motor base 2, and the top rod 111 can move radially relative to the first mesh cover 11. Meanwhile, the side of the second mesh cover 12 close to the first mesh cover 11 is provided with a limiting portion, and the limiting portion is provided with a limiting hole. The limiting hole of the limiting portion can be radially opposite to the position of the top rod 111. When the top rod 111 moves radially, it can be more accurately inserted into or separated from the limiting hole, so that the top rod 111 can connect the second mesh cover 12 through the limiting portion, and prevent the second mesh cover 12 from moving circumferentially. It should be noted that the top rod is only a transmission, and it is not necessarily a straight bar, but it can also be an arc-shaped structure.

[0047] Of course, as another embodiment of the present application, the top rod 111 can also be arranged in the radial direction of the first mesh cover 11 but move circumferentially 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 of the top rod 111 to move. The limiting portion of the top rod 111 and 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 circumferential direction of the second mesh cover 12, and can limit the circumferential movement of the top rod 111. The top rod 111 has a certain movement space in the circumferential direction of the first mesh cover 11, and the radial direction can be arranged to limit the radial movement of the top rod 111. At this time, the movement of the top rod 111 is different from the radial movement of the top rod 111 described above. When the pressing portion 22 presses the side of the top rod 111, the top rod 111 moves along the circumferential direction of the first mesh cover 11. When the top rod 111 moves along the circumferential direction, the bent structure of the top rod 111 is connected to the limiting portion of the second mesh cover 12. That is, the side of one end of the top 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. The connection of the first mesh cover 11 and the second mesh cover 12 can also be completed.

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

[0049] It should be noted that the existing technology requires screws to improve user safety during installation. The technical solution of the embodiment of the present application can be unlocked during the assembly / dismounting of the fan head, and the screw solution can be omitted. However, it is not excluded that other parts of the present solution are locked by screws.

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

[0051] In combinationFigure 2 and Figure 4 As shown in FIG. 1, when the top rod 111 is arranged in the radial direction of the first mesh cover 11 and can move along the radial direction, the elastic member 113 of the embodiment of the present application can be a spring, which is arranged between the top rod 111 and the first mesh cover 11, as shown in FIG. 2. Figure 2 As shown in FIG. 2, the spring can be arranged behind the top rod 111, and one end of the spring is connected with the top rod 111 and the other end is connected with the first mesh cover 11. When the top rod 111 moves, the spring also deforms. For example, when the top rod 111 moves away from the center of the first mesh cover 11 in the radial direction, the spring is compressed at this time, and the bottom of the top rod 111 and the pressing part 22 in the motor base 2 are in the state of pressing each other, so that the spring does not affect the radial movement of the top rod 111 even if it is compressed.

[0052] When the motor base 2 and the fan head 1 are disassembled, the pressing part 22 in the motor base 2 and the top rod 111 are separated from each other, at this time, the top rod 111 is pushed to return to the original state under the action of the elastic member 113, so that the limiting part of the second mesh cover 12 is separated from the top 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 part is arranged at the edge of the second mesh cover 12, one end of the top rod 111 is suitable for limiting cooperation with the limiting part, and the pressing part 22 is suitable for pushing the other end of the top rod 111.

[0054] Through the above scheme, the top rod 111 is arranged in the radial direction of the first mesh cover 11 and moves along the radial direction, when the pressing part 22 in the motor base 2 presses the inner end of the top rod 111, the top rod 111 is more convenient to move, and can move along the predetermined movement track more stably.

[0055] When the top rod 111 is arranged in the radial direction of the first mesh cover 11 and can move along the radial direction, when the top rod 111 is in the natural state, the top rod 111 leaves a 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, 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 along the radial direction away from the center of the first mesh cover 11, the limiting part of the second mesh cover 12 is inserted, so that the first mesh cover 11 and the second mesh cover 12 are connected, and the circumferential movement of the second mesh cover 12 is prevented.

[0056] In some embodiments, the top rod 111 comprises a first top rod segment 1111, an arc-shaped transition segment 1112, and a second top rod segment 1113, the arc-shaped transition segment 1112 being connected between the first top rod segment 1111 and the second top rod segment 1113, the first top rod segment 1111 extending along the radial direction of the first mesh cover 11 to limit the abutment with the limiting portion, and the second top rod segment 1113 extending along the axial direction of the first mesh cover 11 to abut against the abutting portion 22.

[0057] Referring to Figure 6 As shown in the figure, the first top rod segment 1111, the arc-shaped transition segment 1112, and the second top rod segment 1113 of the top rod 111 are integrally formed, and the top rod 111 as a whole is a plate-shaped structure. In actual connection, the first top rod segment 1111 is mainly connected along the radial direction of the inside of the first mesh cover 11, the arc-shaped transition segment 1112 gradually approaches the side of the motor base 2 from one end of the first top rod segment 1111, and the second top rod segment 1113 is arranged along the axial direction of 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 segment 1113 is in contact with the abutting portion 22, and the abutting portion 22 limits the second top rod segment 1113, so that the second top rod segment 1113 does not come off in the normal installation state of the motor base 2 and the fan head 1. At the same time, the end of the first top rod segment 1111 extends into the limiting portion of the second mesh cover 12, completing the connection of the top rod 111 and the second mesh cover 12.

[0058] In the embodiment of the application, the top rod 111 is provided in three different shapes, so that the top rod 111 can be connected with the inside of the first mesh cover 11, and the top rod 111 can also be in contact with the abutting portion 22 in the inside of the motor base 2, and the abutting portion 22 can keep the connection of the top rod 111 and the second mesh cover 12 through the force acting on the second top rod segment 1113.

[0059] In some embodiments, the first top rod segment 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 segment 1113 extends to the side of the first mesh cover 11 away from the second mesh cover 12 to extend towards the motor base 2.

[0060] In actual design, the ejector rod 111 can be arranged on the side of the first mesh cover 11 away from the second mesh cover 12, and the structure design of the ejector rod 111 is the same as the above structure design. When the first mesh cover 11 is connected with the motor base 2, the end of the first mesh cover 11 connected with the motor base 2 is arranged in the motor base 2, so that the ejector rod 111 outside the first mesh cover 11 is in contact with the pressing part 22 inside the motor base 2. Generally, the pressing part 22 is arranged inside the motor base 2, so that the pressing part 22 is protected, and the appearance of the motor base 2 is neat and comfortable. In the embodiment of the application, the ejector rod 111 is arranged inside the first mesh cover 11, i.e. the ejector rod 111 is arranged on the side of the first mesh cover 11 away from the motor base 2. In this way, the neatness of the outside of the fan 100 is maintained, and the ejector rod 111 is prevented from being damaged unintentionally.

[0061] Therefore, the first ejector rod segment 1111 is arranged on the side of the first mesh cover 11 close to the second mesh cover 12, and the end of the second ejector rod segment 1113 extends to the side of the first mesh cover 11 away from the second mesh cover 12 to extend towards the motor base 2. When the motor base 2 is connected with the fan head 1, the pressing between the second ejector rod segment 1113 and the pressing part 22 inside the motor base 2 is facilitated, and the neatness of the outside of the first mesh cover 11 is maintained.

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

[0063] Referring to Figure 2 As shown in the figure, the limiting block 112 can be arranged in multiple or one in the radial direction of the first mesh cover 11. When the limiting block 112 is arranged in multiple, the multiple limiting blocks 112 are arranged in interval along the radial direction. When the limiting block 112 is one, the limiting block 112 can be arranged in extension along the radial direction of the first mesh cover 11. By arranging the limiting block 112, the ejector rod 111 can always move repeatedly along the same radial direction of the first mesh cover 11 when subjected to a pushing force, so that the track of the ejector rod 111 is ensured, and one end of the ejector rod 111 can be pressed by the pressing part 22 of the motor base 2, and the other end can also be connected with the limiting part of the second mesh cover 12 accurately.

[0064] In some embodiments, the plurality of limiting blocks 112 are distributed along the radial direction of the first mesh cover 11. When the plurality of limiting blocks 112 are distributed along the radial direction of the first mesh cover 11, at least one limiting block 112 is arranged at a position close to the edge of the first mesh cover 11, and a space for connecting the second mesh cover 12 is left at the edge position. The first rod segment 1111 of the top rod 111 penetrates into the plurality of limiting blocks 112, and the plurality of limiting blocks 112 limit the first rod segment 1111 in the circumferential direction. The plurality of smaller limiting blocks 112 can save materials and are convenient to arrange, and can limit the first rod segment 1111 at different positions, thereby maintaining the stability of the running path of the first rod segment 1111.

[0065] In some embodiments, the second rod segment 1113 is adapted to extend into the motor base 2; or, the motor base 2 and the fan head 1 are connected by plug-in connection and define a plug-in space, the abutting portion 22 is located in the plug-in space, and the second rod segment 1113 is adapted to extend into the plug-in space to abut against the abutting portion 22.

[0066] In practice, the second rod segment 1113 is curved along the arc-shaped transition segment towards one side of the motor base 2, and extends into the motor base 2 to be close to the abutting portion 22, abuts against the abutting portion 22 when locked, and is separated from the abutting portion 22 when unlocked. The plug-in space allows the second rod segment 1113 to smoothly enter the interior of the motor base 2. Furthermore, when the fan head 1 and the motor base 2 are assembled, the top rod 111 cooperating with the abutting portion 22 of the motor base 2 is hidden in the motor base 2 or 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 limiting plate 115, the first mesh cover 11 is provided with a second limiting plate 114, and the first limiting plate 115 and the second limiting plate 114 form an installation space therebetween. The elastic member 113 is located in the installation space and abuts against the first limiting plate 115 and the second limiting plate 114 at two ends.

[0068] Referring to Figure 4 and Figure 6As shown, the first limiting plate 115 is perpendicular to the first top rod segment 1111, 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 segment 1111, the elastic member 113 is connected with the first top rod segment 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 limiting block 112, the elastic member 113 is arranged above the first limiting plate 115, and the other end of the elastic member 113 is also connected with the second limiting plate 114, when the top rod 111 is pressed by the pressing part 22 and is pushed in the 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 part 22, the top rod 111 is pushed in the direction towards 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 part of the second mesh cover 12.

[0069] The first limiting plate 115 and the second limiting plate 114 are arranged, so that the elastic member 113 is elastically changed to drive the movement of the top rod 111, and the stability of the movement of the top rod 111 is ensured.

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

[0071] Referring to Figure 8 As shown, the opening of the pressing groove 221 is towards the inner wall of the motor base 2, and the pressing groove 221 includes the 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 is connected with the motor base 2, and the arc-shaped pressing surface starts to press the top rod 111, the second top rod segment 1113 of the top rod 111 advances along the curvature of the arc-shaped pressing surface, until the fan head 1 is locked with the motor base 2, at this time, the second top rod segment 1113 of the top rod 111 is just arranged inside the pressing groove 221, so that the second top rod segment 1113 is limited and also kept in a static state, and the end of the first top rod segment 1111 of the top rod 111 also penetrates into the limiting part of the second mesh cover 12, at this time, the first mesh cover 11 and the second mesh cover 12 are in a reliable connection state, and the motor base 2 and the fan head 1 are also in a connection state.

[0072] In some embodiments, the pressing part 22 includes a pressing segment 222 and a connecting segment 223, the pressing segment 222 and the connecting segment 223 are connected and form the pressing groove 221 which is open on one side, at least part of the top rod 111 is adapted to extend into the pressing groove 221 from the open side of the pressing groove 221, and the arc-shaped pressing surface is arranged on the pressing segment 222.

[0073] Continuing to refer toFigure 8 As shown, the edge part of the pressing section 222 is an arc-shaped pressing surface, which can ensure that the second rod section 1113 of the top rod 111 gradually enters the pressing groove 221 along the arc-shaped pressing surface, and at this time, the fan head 1 is connected with the motor base 2.

[0074] In practice, when at least part of the top rod 111 contacts the pressing section 222, the top rod 111 can be pushed radially away from the center of the first mesh cover 11, that is, the connection between the first mesh cover 11 and the second mesh cover 12 at the edge can be achieved when at least part of the top rod 111 contacts the pressing section 222, but the top rod 111 has not yet completely entered the pressing groove 221 or has not yet been positioned. The embodiment of the present application arranges the pressing section 222 in such a structure that the second rod section 1113 of the top rod 111 enters the inclined clamping surface along the arc-shaped pressing surface smoothly, so as to be positioned in the pressing groove 221 formed by the inclined clamping surface and the connecting section 223. The second rod section 1113 is not easy to be loosened or separated from the pressing section 22.

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

[0076] In practice, the fan head 1 includes the first mesh cover 11, the second mesh cover 12, and the fan blade components inside them. The fan blade components can be initially and simply connected with the first mesh cover 11 and the second mesh cover 12, and then the fan head 1 is rotated relative to the motor base 2. When rotating, the bottom of the top rod 111 of the first mesh cover 11 is just rotated to the pressing part 22 inside the motor base 2, so that the pressing part 22 presses the top rod 111 to move, thereby pushing the top rod 111 to move away from the center of the first mesh cover 11 to lock the second mesh cover 12.

[0077] Rotating the fan head 1 relative to the motor base 2 facilitates the connection between the fan head 1 and the motor base 2, and facilitates the gradual pressing of the top rod 111 of the fan head 1 by the pressing part 22 inside the motor base 2 when the motor base 2 rotates relative to the fan head 1, so that the first mesh cover 11 and the second mesh cover 12 of the fan head 1 are also connected.

[0079] In practice, the first screwing part 21 extends axially along the motor base 2, the second screwing part 118 extends axially along the connecting hole 116 of the first mesh cover 11, and the diameter of the second screwing part 118 can be set to be smaller than the diameter of the first screwing part 21, the second screwing part 118 is inserted into the first screwing part 21, and the inner wall of the second screwing part 118 can be provided with a plurality of spaced limiting protrusions 117, and the inner wall of the first screwing part 21 is provided with a plurality of spaced 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 protrusions 117 of the second screwing part 118 are clamped into the limiting recesses 23 of the inner wall of the first screwing part 21, so that the fan head 1 and the motor base 2 are clamped, and then a screwing thread can be provided at the inner edge of the first screwing part 21, and a small amount of thread is also provided at the position where the outer part of the second screwing part 118 contacts the edge of the first screwing part 21, so that the first screwing part 21 and the motor base 2 are connected by the second screwing part 118 through a small amount of thread rotation, and clamped by the limiting protrusions 117 and the limiting recesses 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 a fan blade 4, the fan blade 4 includes a connecting shaft 5 and a fan blade, the fan blade is located in the fan head 1 and is sleeved on the outside of the connecting shaft 5, both ends of the connecting shaft 5 are rotatably supported on the first mesh cover 11 and the second mesh cover 12 through bearing structures, and the connecting shaft 5 is power-connected with a driving member of the motor base 2.

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

[0083] At this time, the connecting shaft 5 can be rotatably connected between the first mesh cover 11 and the second mesh cover 12 through a bearing structure, so as to ensure the rotatable connection between the wind blade and the first mesh cover 11 and the second mesh cover 12, in addition, it should be noted that a locking nut can be sleeved on the side of the connecting shaft 5 close to the second mesh cover 12, so as to prevent the wind blade from moving axially on the connecting shaft 5.

[0084] In some embodiments, the motor base 2 is provided with a driving part, and the fan blade 4 is arranged in the fan head 1 and is in power connection with the driving part.

[0085] Specifically, the connecting shaft 5 of the fan blade 4 can be connected with the driving part, and the driving part can be a driving shaft of the motor, so that the motor in the motor base 2 can drive the connecting shaft 5 to rotate in the rotating process, thereby driving the rotation of the wind blade.

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

[0087] The axial flow fan blade is suitable for driving the airflow in the fan head 1 to flow to the air outlet hole along the axial direction of the axial flow fan blade. That is to say, the fan blade 4 of the fan 100 in the present application is different from the conventional centrifugal fan blade 4, and can realize axial air inlet and axial air outlet. In actual operation, the axial flow fan blade rotates, and the airflow behind the axial flow fan blade flows forward along the axial direction of the axial flow fan blade, and then flows to the air outlet hole in the front part of the fan head 1 to be delivered to the face of the user.

[0088] It should be noted that the fan head 1 can be provided with an air inlet hole, which can be arranged on the rear side of the fan head 1 for axial air inlet, or arranged on the circumferential outer side of the fan head 1 for oblique air inlet, so as to realize the air inlet function of the fan head 1. The airflow entering the fan head 1 can flow to the axial rear end of the axial fan blade, and then flow forward along the axial direction of the axial fan blade to the air outlet hole under the driving action of the axial fan blade. In particular, the air inlet hole can be arranged on the rear side of the fan head 1, and the motor base 2 is provided with a heat dissipation flow channel, so that the heat dissipation flow channel is communicated with the air inlet hole. Then, the airflow is driven to flow to the user from the air inlet hole after being driven by the driving member and being cooled in the heat dissipation flow under the driving action of the axial fan blade. This not only facilitates air supply, but also realizes 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 position 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. Thus, the fan 100 in the present application is different from the conventional cross-flow impeller. It should be noted that the conventional tower fan uses a cross-flow impeller, and the radial dimension of the tower fan at each position in the axial direction does not change significantly. However, the radial dimension of the fan head 1 in the present application is much larger than the radial dimension of the motor base 2 at the position of the driving member.

[0090] At the same time, the arrangement of the axial fan blade facilitates more stable placement of the fan head 1 and the motor base 2 compared with the centrifugal fan blade, thereby ensuring the stability of the position state of the fan 100.

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

[0092] In addition, the fan head 1 is adapted to be connected with the motor base 2 in a first direction when in an initial position, the first direction intersects with the vertical direction, and the fan head is arranged to be swingable up and / or down and / or left and right relative to the motor base from the initial position.

[0093] That is, when the fan head 1 is in the initial position relative to the motor base 2, the fan head 1 can be moved relative to the motor base 2 in the first direction, so as to connect and fix the fan head 1 with the motor base 2. For example, if the first direction is along the horizontal direction, the fan head 1 can be installed on 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 fan head 1 and the motor base 2 along the horizontal direction.

[0094] In addition, the first direction can also form a certain inclination angle relative to the horizontal direction, and all intersect with the vertical direction, that is, the first direction can 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, the fan head 1 is arranged to be swingable 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 with 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 jointly installed on the base 3, and the fan head 1 can be driven to adjust and adjust in different directions upward, downward, left and right relative to the base 3, at this time, the fan head 1 can be adjusted to be parallel to the vertical direction, so that the adjustment range of the fan head 1 is larger, and the air supply demand of the user in more directions is met.

[0096] In some embodiments, the base 3 is further included, and the base 3 is adapted to be supported on a placement surface, and the motor base 2 is installed on the base 3.

[0097] Referring to Figure 1 For the floor fan 100, the base 3 can be arranged to be higher, the base 3 can be arranged to be higher, and can also be arranged to be a desktop type, and can also be arranged to be a wall-mounted type. If the base 3 is arranged on the ground or the desktop, the bottom of the base 3 is generally provided with a disc for supporting the ground or the desktop, and the end of the base 3 away from the ground is provided with the motor base 2, and the motor base 2 is installed with the fan head 1, and the base 3 is used to support the motor base 2 and the fan head 1. In the working and non-working states of the fan 100, the base 3 is supported on the placement surface, which can make the fan 100 placed more stably. The fan 100 can be supported on the placement surface through the base 3, that is, the fan 100 can be placed on the ground. Such a floor fan is beneficial to the overall stable placement of the fan 100, or the overall height of the fan 100 can be flexibly adjusted through the base 3 of different heights, which is beneficial to be suitable for different types of application scenarios and meet the different types of use requirements of the user.

This connection mode can be unlocked during the process of assembling or disassembling the fan head 1, and the screw scheme can be omitted.

[0103] That is to say, when the first mesh cover 11 and the second mesh cover 12 are connected with the motor base 2, mainly the first mesh cover 11 is connected with the motor base 2, and after the first mesh cover 11 is connected with the motor base 2, the top rod 111 is pushed by the pressing part 22 to be connected with 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 application is convenient to install and disassemble, and installation time is saved.
