[0037] Furthermore, it should be emphasized that the power supply of a conventional fan is generally located in the base, and the base needs to be connected to an external power supply before it can be used. In this embodiment, a first power supply is arranged in the body component 3. Thus, when the fan is used handheld, after removing the base component 4 below, the first power supply can still provide power for the fan without the need for additional charging equipment.

[0038] In a specific embodiment: Figure 3 As shown, the body assembly 3 also has a body charging seat, and the body charging seat is provided with a first charging terminal for charging the first power source.

[0039] Specifically, the first power source can be charged through the body charging stand, and the first power source can be a rechargeable battery; and the power source of the body charging stand can come from an external power source or from the base assembly 4.

[0040] In a specific embodiment: Figure 4 As shown, the base assembly 4 includes a base body 41 and a base charging slot 42. The base charging slot 42 is located above the base body 41. A second charging terminal is provided on the base charging slot 42, and the second charging terminal matches the first charging terminal.

[0041] In this way, when the body component 3 and the base component 4 are matched, the body charging seat under the body component 3 is just placed in the base charging slot 42. In this way, the base charging slot 42 and the body charging seat are matched, that is, through the cooperation of the first charging terminal and the second charging terminal, the first power source is charged through the base charging slot 42.

[0042] More specifically, the first charging terminal and the second charging terminal are both magnetically attractive charging terminals. After the body component 3 and the base component 4 are matched, the first charging terminal and the second charging terminal are adsorbed to charge the first power source. At this time, the fan is used as a desktop fan.

[0043] In a specific embodiment: the base component 4 has a second power supply, the second power supply can be a rechargeable battery or a power bank; the second power supply can provide power for the entire fan alone, and the second power supply can charge the first power supply; specifically, a charging port is provided on the base component 4, and the second power supply can be charged through the charging port.

[0044] In a specific embodiment: Figure 5 and Figure 6As shown, the bracket 21 is a U-shaped structure, including a first side, a second side and a third side connected in sequence, the first side and the third side are parallel, the second side is fixed to the rear net assembly 2 through the motor bracket 5, and the fuselage assembly 3 is located in the space formed by the first side and the third side, that is, the first side and the third side clamp the fuselage assembly 3 therebetween.

[0045] Specifically, the bracket 21 includes a first side and a third side parallel to each other, a second side is arranged between the first side and the third side, and the second side has a certain curvature; in addition, the fan provided in this embodiment also includes a motor, the motor is located in the motor bracket 5, the outer surface of the motor bracket 2 is an arc-shaped structure, and the second side is fitted with the outer surface of the motor bracket 5 to achieve connection; the motor inside the motor bracket 2 can drive the blades in the front mesh component 1 and the rear mesh component 2 to rotate.

[0046] In a specific embodiment: a metal slide contact 22 is provided on the first side, a metal slide 32 is provided on one side surface of the fuselage assembly 3, the metal slide contact 22 cooperates with the metal slide 32, and the metal slide 32 can move up and down along the metal slide contact 22, thereby realizing stepless height adjustment.

[0047] Specifically, the first side is a sheet-like structure, on the inner side of which a metal slide contact 22 is provided, and on the side of the body assembly 3 that cooperates with the first side a metal slide 32 is provided, and the metal slide contact 22 cooperates with the metal slide 32 in a variety of ways, for example, a groove is provided on the metal slide 32, the metal slide contact 22 is located in the groove, and can slide up and down along the groove.

[0048] In addition, in order to make the fit between the fuselage component 3 and the bracket 21 more secure, in a specific implementation, the width of the fuselage component 3 is greater than the width of the first side and the third side, and a bracket fitting groove 34 is provided on the fuselage component 3, and the third side is located in the bracket fitting groove 34.

[0049] Moreover, in this embodiment, the metal slide 32 is electrically connected to the first power source, and the electric power is transferred to the motor inside the motor bracket 2 through the conductivity of the metal or a small number of connecting wires, thereby providing power for the motor; this embodiment utilizes the conductivity of the metal, so that there are fewer wires inside the fan, thereby avoiding difficulties in height adjustment caused by too many wires.

[0050] In a specific embodiment: Figure 7 As shown, a positioning hole 33 is provided on the other side of the fuselage assembly 3 , and a positioning contact 23 is provided on the third side, and the positioning contact 23 cooperates with the positioning hole 33 .

[0051] Specifically, the other side surface of the fuselage assembly 3 is opposite to the above-mentioned side surface, and the other side surface cooperates with the third side. A positioning contact 23 is provided on the inner side of the third side. The positioning contact 23 cooperates with the positioning hole 33 and is mainly used for fixing after the height is adjusted to a suitable position.

[0052] In a specific embodiment: the bracket 21 is movably connected to the fuselage assembly 3 through the metal slide contact 22 and the positioning contact 23, and the bracket 21 rotates along the metal slide contact 22 and the positioning contact 23 to adjust the pitch angle of the rear net assembly.

[0053] Specifically, the metal slide contact 22 and the positioning contact 23 are both raised structures. The metal slide contact 22 can rotate in the corresponding groove of the metal slide 32, and the positioning contact 23 can rotate in the corresponding positioning hole 33; in this way, by gently pressing down or pushing up the rear mesh component 2, the rear mesh component 2 and the front mesh component 1 can be rotated downward or upward together through rotation on both sides, thereby adjusting the fan angle to meet the needs of users.

[0054] In a specific embodiment: the positioning hole 33 is a groove structure, a plurality of positioning holes 33 are provided, and the plurality of positioning holes 33 are evenly arranged along the axial direction of the fuselage assembly 3, and the positioning contact 23 cooperates with different positioning holes 33 to adjust the fan height.

[0055] Specifically, in order to meet the height requirements of users as much as possible, the spacing between adjacent positioning holes 33 is small, and even adjacent positioning holes 33 are in contact. The connection between the fuselage assembly 3 and the bracket 21 can be achieved by snapping the positioning contacts 23 into the positioning holes 33.

[0056] The fan provided in this embodiment is specifically a portable fan that combines handheld and desktop modes. Adjustments have been made to the traditional fan. In order to achieve the switching between handheld and desktop modes, the base assembly and the body assembly are separated.

Both the base assembly and the body assembly have power supplies to support offline handheld operation. In addition, the base assembly serves as a support and a charging station, and the built-in battery can support offline charging, and is also responsible for wiring charging. When carrying outdoors, you only need to carry the base to achieve ultra-long battery life.

[0057] Specifically, when the fan in this embodiment is used as a desktop fan, its working state is: adjust the height of the body assembly 3, and place part of the body assembly 3 into the base charging slot 42. When the power is sufficient, the power cord can be directly disconnected to support use on tables in various locations. When the power is insufficient, the base assembly 4 can be connected to the power supply for use; when in a handheld or portable working state: appropriately adjust the positioning contact 23 on the bracket 21, and adjust the length of the body handheld portion to an appropriate length for handheld use. The first power supply inside the body assembly 3 can also complete a certain period of battery life, which is convenient for users to carry outdoors; in addition, the fan provided in this embodiment relies on the metal sliding contact 22 and the positioning contact 23, which can not only meet the up and down sliding adjustment of the fan, but also rotate the entire front mesh assembly 1 and the rear mesh assembly 2 to achieve the adjustment of the pitch angle.

[0058] The fan provided in this embodiment can be used on a table or as a handheld device, meeting the user's usage needs in more scenarios and can be switched at any time. The power reserves in the base assembly and the body assembly increase the fan's endurance. The metal sliding contact connection makes the fan more flexible to adjust, reduces the use of internal wiring, and can effectively avoid wire jamming and pulling problems.

[0059] In summary, it is easy for those skilled in the art to understand that, under the premise of no conflict, the above-mentioned advantageous technical features can be freely combined and superimposed.

[0060] The above are only preferred embodiments of the present invention and are not intended to limit the present invention in any form.
