Specifically, the utility model provides a fan has two kinds of states:

firstly, the pulling plate component 4 is contacted with the lower end of the base component 2, and the whole fan is supported by the base component, and the fan is a desk fan;

secondly, when the pulling plate component 4 below the base component 2 is pulled, the pulling plate component 4 can drive the elastic component 3 to compress, so that a gap for clamping is generated between the base component 2 and the pulling plate component 4, and at the moment, the fan can be clamped on a certain structure, such as a bed head;

when the fan needs to be restored to the first state from the second state, the fan is taken down from the clamped structure, the elastic component 3 needs to be restored to the initial state, the pulling plate component 4 moves towards the base component 2 under the effect of restoring force, and the fan returns to the first state due to the contact of the pulling plate component and the base component.

The fan provided by the embodiment has two use forms; and, through setting up power supply module 1 in base module 2, and elastic component 3 cover is established on base module 2, and power supply module 1 and elastic component 3 are coaxial setting promptly, compare and place side by side in traditional spring and battery, and this embodiment obviously can make the volume reduction of fan, that is to say, this embodiment has increased the function of centre gripping on the basis of keeping the original outward appearance of desk fan.

In a specific embodiment:

as shown in fig. 1 and 3, the elastic assembly 3 includes a spring 31 and a bottom plate 32, the bottom plate 32 has a sliding groove 33, the spring 31 is located in the sliding groove 33, the lower end of the bottom plate 32 is connected to the pulling plate assembly 4, and the upper end of the bottom plate 32 has a protrusion capable of driving the spring 31 to move downward.

Specifically, as shown in fig. 4 and 5, the bottom plate 32 may be a hollow cylindrical structure, a sliding groove 33 is formed on an inner surface of the cylindrical structure, the spring 31 is located in the sliding groove 33, and the sliding groove 33 provides a radial direction limitation for the up-and-down movement of the spring 31; of course, only part of the bottom plate 32 may be a hollow circumferential structure, and the rest may be a plate-like structure; however, it should be emphasized that, regardless of the specific structure of the bottom plate 32, at the edge of the upper end of the bottom plate 32, there is a protrusion extending toward the spring 31 side, and the protrusion and the spring are located on the same vertical plane in the axial direction; thus, when the pulling plate assembly 4 pulls the bottom plate 32 to move downward, the protrusion contacts the upper end of the spring 31, and the spring 31 is compressed downward.

In a specific embodiment: the upper end of the bottom plate 32 has an upper limit structure 34 for limiting the spring 31.

When the fan needs to be restored from the clamped state to the desk fan state, the clamp between the pulling plate assembly 4 and the base assembly 2 is removed, the spring 31 needs to be restored to the initial state, the spring 31 moves upward along the sliding groove 33 under the restoring force, and the upper limit structure 34 just prevents the spring 31 from being pushed out of the bottom plate 32 under the combined action of the inertial force and the restoring force when the initial state is restored.

In a specific embodiment: as shown in fig. 6, the base assembly 2 includes a base body 21 and a spring post 22, the spring post 22 is located on the base body 21, the spring post 22 is hollow, the power module 1 is located in the hollow, and the spring 31 is sleeved outside the spring post 22.

Specifically, the spring column 22 may also be referred to as a battery cavity, and the inside is used for placing the power supply module 1, in this embodiment, the power supply module 1 is a battery, and the outside is used for sleeving the spring 31; that is, the battery, the spring column 22 and the spring 31 are arranged in sequence from inside to outside, so that the battery and the spring 31 are coaxially arranged, and the increase of the volume of the whole fan caused by the increase of a clamping function on the table fan is avoided; the coaxial setting of this embodiment keeps original outward appearance when realizing that the fan increases clamping function, and it is littleer to get the fuselage volume, and the complete machine carries more conveniently.

More specifically, the base body 21 has a disc-shaped structure, and the base body 21 with the disc-shaped structure extends upwards to form a column structure, i.e. a spring column; of course, the base body 21 may have other shapes, such as square, triangular, etc., and is mainly matched with the pulling plate assembly 4 and stably placed on the supporting surface.

In a specific embodiment: as shown in fig. 6, the base assembly 2 further includes a lower limiting structure 23, and the lower limiting structure 23 is a protrusion that is protruded along the outer ring of the lower end of the spring post 22 in the direction away from the axial center.

Specifically, at a section of the spring post 22 close to the base body 21, a circle or a half circle of protrusion extends outward from the outer peripheral surface thereof, and when the pulling plate assembly 4 pulls the bottom plate 32 to move downward, the spring 31 is driven to compress downward, and at this time, the spring 31 is prevented from moving downward all the time and being separated from the spring post 22 by the protrusion.

In addition, as shown in fig. 4, in order to avoid the lower limit structure 23, the bottom plate 32 is further provided with a chute 36.

In a specific embodiment: as shown in fig. 6, the lower end of the base body 21 is provided with a pull hole 24 for matching with the pull plate assembly 4; the pulling plate component 4 is of a plate-shaped structure; the pull hole 24 is a notch formed at the lower end of the base body 21, and the notch is used for placing the plate-shaped pull plate assembly 4.

In addition, as shown in fig. 8, the pulling plate assembly 4 is provided with a handle fastening position 41, which is also a notch and is mainly used for providing convenience for a user when pulling the pulling plate assembly 4; that is, when the fan needs to be clamped on a structure, an operator puts fingers into the cavity formed by the pulling plate assembly 4 and the base assembly 2 through the notches and pulls the pulling plate assembly 4 downwards, at this time, the bottom plate 32 moves downwards along with the pulling plate assembly 4 and compresses the spring 31, so that a gap for clamping is formed between the base assembly 2 and the pulling plate assembly 4.

In a specific embodiment:

as shown in fig. 7, a stopper table 25 for stopping the power module 1 is provided in the hollow of the spring column 22.

Specifically, the limiting table 25 is: extending along the inner surface of the spring post 22 towards the center of the spring post 22, wherein the extended part is a limit table 25; therefore, the accurate installation of the battery can be realized, and the influence on the performance of the whole fan caused by the infinite downward movement of the battery is avoided.
