The present disclosure will be described in detail below with reference to <FIG> and embodiments.

As shown in <FIG> and <FIG>, the present invention provides a storable fan, including fan head <NUM>, support rod <NUM>, and base <NUM>. The fan head <NUM>, the support rod <NUM>, and the base <NUM> are connected detachably. First accommodating groove <NUM> and second accommodating groove <NUM> are formed in the base <NUM>. The storable fan has a used state and a stored state. The used state refers to a state in which various components of the fan are assembled for blowing or are ready for blowing. When the storable fan is in the used state, the fan head <NUM>, the support rod <NUM>, and the base <NUM> are connected sequentially. The stored state refers to a state in which various components of the fan are arranged for storage. When the storable fan is in the stored state, the fan head <NUM> is stored in the first accommodating groove <NUM>. The support rod <NUM> is stored in the second accommodating groove <NUM>.

According to the storable fan provided by the above embodiment, the fan head <NUM>, the support rod <NUM> and the base <NUM> are connected detachably, for ease of detachment of the storable fan. Both the fan head <NUM> and the support rod <NUM> can be stored in the base <NUM>. The storage process can be accomplished without detaching such fasteners as screws and nuts. The storable fan is stored simply and conveniently, with a small footprint.

The first accommodating groove <NUM> is formed in one side of the base <NUM>. The second accommodating groove <NUM> is formed in the other opposite side of the base <NUM>. For example, as shown in <FIG>, the first accommodating groove <NUM> is formed in a top of the base <NUM>. The second accommodating groove <NUM> is formed in a bottom of the base <NUM>. The fan head <NUM> and the support rod <NUM> can be respectively stored at two sides of the base <NUM>. This makes full use of a space of the base <NUM>, and prevents mutual interference between the fan head <NUM> and the support rod <NUM>.

According to the storable fan provided by the embodiment of the present disclosure, specifically, detachable connection between the fan head <NUM>, the support rod <NUM>, and the base <NUM> is preferably realized by insertion. The operation is simple, convenient, and easy-to-realize. Specifically, as shown in <FIG>, two ends of the support rod <NUM> are respectively provided with first insertion portion <NUM> and second insertion portion <NUM>. The fan head <NUM> includes guard <NUM> and connecting segment <NUM> rotatably connected to the guard <NUM>. Fixing hole <NUM> is formed in the base <NUM>. When the storable fan is in the used state, a first end and a second end of the support rod <NUM> are respectively connected to the connecting segment <NUM> and the fixing hole <NUM>. The first insertion portion <NUM> of the support rod <NUM> is inserted with a connecting portion, while the second insertion portion <NUM> of the support rod <NUM> is inserted with the fixing hole <NUM>. When the storable fan is in the stored state, the connecting segment <NUM> is fixed in the first accommodating groove <NUM>. A shape of the first accommodating groove <NUM> is matched with a contour of a connecting end.

In order to realize stable connection and convenient detachment for the two ends of the support rod <NUM> with the fan head <NUM> and the base <NUM>, the two ends of the support rod <NUM> may be respectively provided with a corresponding structural component.

Optionally, as shown in <FIG> and <FIG>, a first end of the support rod <NUM> connected to the fan head <NUM>, namely the first insertion portion <NUM>, is provided thereon with first pressing plate <NUM>. First engagement member <NUM> and first button <NUM> are provided on the first pressing plate <NUM>. A first engagement portion cooperated with the first engagement member <NUM> is provided on the fan head <NUM>. By pressing the first button <NUM>, the first pressing plate <NUM> can drive the first engagement portion to move inward, thereby generating an acting force opposite to a movement direction. After the first button <NUM> is loosened, the first pressing plate <NUM> and the first button <NUM> are restored under the acting force. Herein, the acting force may be generated by fourth elastic piece <NUM> between the first pressing plate <NUM> and the support rod <NUM>. Alternatively, the first pressing plate <NUM> may further be provided as a cantilever structure integrally connected to the support rod <NUM>; and the acting force is generated by deformation of the first pressing plate <NUM>. When the storable fan is used, the first button <NUM> at the end of the support rod <NUM> is pressed, such that the first pressing plate <NUM> and the first engagement member <NUM> move inward. The first insertion portion <NUM> at the end of the support rod <NUM> is inserted into the connecting segment <NUM> of the fan head <NUM>. After the first button <NUM> is loosened, the first pressing plate <NUM> and the first engagement member <NUM> are restored reversely. The first engagement member <NUM> is engaged with the first engagement portion on the connecting segment <NUM> of the fan head <NUM> to realize installation and fixation for the fan head <NUM> and the support rod <NUM>. When the fan head <NUM> and the support rod <NUM> are to be detached, the first button <NUM> at the end of the support rod <NUM> is pressed, such that the first pressing plate <NUM> and the first engagement member <NUM> move inward, and the first engagement member <NUM> is separated from the first engagement portion. The first insertion portion <NUM> at the end of the support rod <NUM> is moved out of the connecting segment <NUM> of the fan head <NUM>. After the first button <NUM> is loosened, the first pressing plate <NUM> and the first engagement member <NUM> are restored reversely to realize detachment for the fan head <NUM> and the support rod <NUM>.

Likewise, as shown in <FIG> and <FIG>, a second end of the support rod <NUM> connected to the base <NUM>, namely the second insertion portion <NUM>, is provided thereon with second pressing plate <NUM>. Second engagement member <NUM> and second button <NUM> are provided on the second pressing plate <NUM>. A second engagement portion cooperated with the second engagement member <NUM> is provided in the fixing hole <NUM> of the base <NUM>. By pressing the second button <NUM>, the second pressing plate <NUM> can drive the second engagement portion to move inward, thereby generating an acting force opposite to a movement direction. After the second button <NUM> is loosened, the second pressing plate <NUM> and the second button <NUM> are restored under the acting force. Herein, the acting force may be generated by fifth elastic piece <NUM> between the second pressing plate <NUM> and the support rod <NUM>. Alternatively, the second pressing plate <NUM> may further be provided as a cantilever structure integrally connected to the support rod <NUM>; and the acting force is generated by deformation of the second pressing plate <NUM>. When the storable fan is used, the second button <NUM> at the end of the support rod <NUM> is pressed, such that the second pressing plate <NUM> and the second engagement member <NUM> move inward. The second insertion portion <NUM> at the end of the support rod <NUM> is inserted into the fixing hole <NUM> of the base <NUM>. After the second button <NUM> is loosened, the second pressing plate <NUM> and the second engagement member <NUM> are restored reversely. The second engagement member <NUM> is engaged with the second engagement portion in the fixing hole <NUM> of the base <NUM> to realize installation and fixation for the base <NUM> and the support rod <NUM>. When the base <NUM> and the support rod <NUM> are to be detached, the second button <NUM> at the end of the support rod <NUM> is pressed, such that the second pressing plate <NUM> and the second engagement member <NUM> move inward, and the second engagement member <NUM> is separated from the second engagement portion. The second insertion portion <NUM> at the end of the support rod <NUM> is moved out of the fixing hole <NUM> of the base <NUM>. After the first button <NUM> is loosened, the first pressing plate <NUM> and the first engagement member <NUM> are restored reversely to realize detachment for the base <NUM> and the support rod <NUM>.

On the basis of the above implementations, for the sake of more convenient and quicker installation, as shown in <FIG> and <FIG>, an end of the first engagement member <NUM> away from the second end (the second insertion portion <NUM>) of the support rod <NUM> is provided with an outward wedge-shaped surface. With the wedge-shaped surface, when the first insertion portion <NUM> of the support rod <NUM> is inserted into the connecting segment <NUM> of the fan head <NUM>, the first button <NUM> is unnecessarily pressed. During insertion, the connecting segment <NUM> is interfered with the wedge-shaped surface of the first engagement member <NUM>, and the first engagement member <NUM> and the first pressing plate <NUM> are moved inward forcibly. After the insertion is in place, the wedge-shaped surface of the first engagement member <NUM> is released from the connecting segment <NUM>, and the first engagement member moves reversely to engage with the first engagement portion. Likewise, an end of the second engagement member <NUM> away from the first end (the first insertion portion <NUM>) of the support rod <NUM> is provided with an outward wedge-shaped surface. With the wedge-shaped surface, when the second insertion portion <NUM> of the support rod <NUM> is inserted into the fixing hole <NUM> of the base <NUM>, the second button <NUM> is unnecessarily pressed. During insertion, an inner wall of the fixing hole <NUM> is interfered with the wedge-shaped surface of the second engagement member <NUM>, and the second engagement member <NUM> and the second pressing plate <NUM> are moved inward forcibly. After the insertion is in place, the wedge-shaped surface of the second engagement member <NUM> is released from the inner wall of the fixing hole <NUM>, and the second engagement member <NUM> moves reversely to engage with the second engagement portion. With the wedge-shaped surfaces on the first engagement member <NUM> and the second engagement member <NUM>, when the fan is assembled, various structural components can be fixedly connected without pressing. The structural components can also be detached only by pressing. Therefore, the one-button operation is realized.

When the fan head <NUM> is stored in the first accommodating groove <NUM> of the base <NUM>, the connecting segment <NUM> of the fan head <NUM> is attached to the guard <NUM> by rotating. The connecting segment <NUM> is then placed into the first accommodating groove <NUM>, thereby realizing storage of the fan head <NUM>. In this case, the guard <NUM> may rotate relative to the connecting segment <NUM> to make an overall structure of the fan head <NUM> and the base <NUM> unstable. In view of this, as shown in <FIG>, <FIG> and <FIG>, a first locking piece is provided on the fan head <NUM>. A second locking piece is provided on the base <NUM>. In the stored state shown in <FIG>, the first locking piece is locked with the second locking piece. Specifically, the first locking piece is provided on the guard <NUM>. Through cooperation between the first locking piece and the second locking piece, the fan head <NUM> and the base <NUM> can further be limited. This prevents the guard <NUM> from moving relative to the base <NUM> to make the storage structure unstable. Preferably, as shown in <FIG> and <FIG>, the first locking piece is locking rod <NUM>. Stationary blocking portion <NUM> is provided on a surface of the locking rod <NUM> along the radial direction of the locking rod <NUM>. The second locking piece is locking hole <NUM> formed in the base <NUM>. Movable blocking portion <NUM> is provided on an inner wall of the locking hole <NUM>. The movable blocking portion <NUM> is extended into the locking hole <NUM> under an elastic force. When the locking rod <NUM> is inserted into the locking hole <NUM>, the stationary blocking portion <NUM> pushes away the movable blocking portion <NUM> and is inserted under the movable blocking portion. The blocking portion is restored under the elastic force to realize engagement between the movable blocking portion <NUM> and the stationary blocking portion <NUM>, as well as locking between the locking rod <NUM> and the locking hole <NUM>. When the locking rod <NUM> is to be moved out of the locking hole <NUM>, the locking rod <NUM> is moved outward by an external force. With the external force, the stationary blocking portion <NUM> pushes the movable blocking portion <NUM> forcibly to realize separation between the locking rod <NUM> and the locking hole <NUM>. More preferably, as shown in <FIG> and <FIG>, the movable blocking portion <NUM> is connected to fourth button <NUM> through connecting rod <NUM> rotatably connected to the base <NUM>. The fourth button <NUM> is provided at a side of the base <NUM>. First elastic piece <NUM> is provided between the fourth button <NUM> and the button <NUM>. By pressing the fourth button <NUM> to overcome an elastic restoring force of the first elastic piece <NUM>, the connecting rod <NUM> rotates, thereby driving the movable blocking portion <NUM> to move toward a direction away from a center of the locking hole <NUM>. Therefore, the limitation between the movable blocking portion <NUM> and the stationary blocking portion <NUM> can be released. After the fourth button <NUM> is loosened, the fourth button <NUM> is restored under an action of the first elastic piece <NUM>. In addition, propping member <NUM> is provided at a bottom of the locking hole <NUM>. The propping member <NUM> is connected to the base <NUM> through second elastic piece <NUM>. The locking rod <NUM> abuts against the propping member <NUM> when entering the locking hole <NUM> in assembly, so as to overcome an elastic restoring force of the second elastic piece <NUM>. After the fourth button <NUM> is pressed for unlocking, the second elastic piece <NUM> can pop up the fan head <NUM> automatically through the elastic restoring force. Therefore, the operation is more convenient.

In some implementations, as shown in <FIG> and <FIG>, third locking piece <NUM> is provided in the first accommodating groove <NUM>. The connecting segment <NUM> is locked with the third locking piece <NUM> in the stored state, such that a connection strength between the base <NUM> and the connecting segment <NUM> can be increased. The third locking piece <NUM> is preferably an elastic gripping jaw structure. An inner wall of the elastic gripping jaw structure is matched with an external contour of the connecting segment <NUM>. The elastic gripping jaw structure may be provided at one end of the first accommodating groove <NUM>. During storage, one end of the connecting segment <NUM> can be inserted into the elastic gripping jaw structure. The first locking piece is then connected to the second locking piece.

In some implementations, the support rod <NUM> is a telescopic rod shown in <FIG>. On one hand, when the storable fan is in the used state, as shown in <FIG>, the height of the electric fan can be adjusted through the telescopic rod, such that the fan head <NUM> works at different heights to meet actual requirements of a user. On the other hand, when the storable fan is in the stored state, the support rod <NUM> is retracted as shown in <FIG>, for better storage of the support rod <NUM>. As shown in <FIG>, the second accommodating groove <NUM> in the base <NUM> is matched with the contour of the support rod <NUM> in the retracted state.

On the basis of the above implementations, the specific structure of the support rod <NUM> may be various forms of the telescopic rod in the prior art, provided that the objective of the present disclosure can be realized.

Optionally, as shown in <FIG> and <FIG>, the support rod <NUM> includes first rod <NUM> and second rod <NUM> connected to each other. The first rod <NUM> is nested in the second rod <NUM>. A plurality of first grooves <NUM> are formed in an outer wall of the first rod <NUM> along the axial direction of the first rod <NUM>. A control assembly, limiting hole <NUM> and locating pin <NUM> are provided on the second rod <NUM>. The locating pin <NUM> is located in the limiting hole <NUM>. The control assembly is configured to limit the locating pin <NUM> in a locked state of being simultaneously engaged in the first groove <NUM> and the limiting hole <NUM>. The control assembly is further configured to release the locked state of the locating pin <NUM>. Specifically, the second rod <NUM> includes first wall <NUM> and second wall <NUM>. The first rod <NUM> is sleeved in the second wall <NUM>. The control assembly includes slider <NUM> and third elastic piece <NUM>. The slider <NUM> is slidably provided between the first wall <NUM> and the second wall <NUM>. A side of the slider <NUM> facing the second wall <NUM> is provided with second groove <NUM>. When the limiting hole <NUM> directly faces the first groove <NUM>, the slider <NUM> limits the locating pin <NUM> in the limiting hole <NUM> and the first groove <NUM> simultaneously under an elastic force of the third elastic piece <NUM>. When the storable fan is used, the slider <NUM> is pushed to overcome an elastic restoring force of the third elastic piece <NUM> to slide in mounting groove <NUM> between the first wall <NUM> and the second wall <NUM>. As shown in <FIG>, at an extreme position, the second groove <NUM> in the slider <NUM> can directly face the limiting hole <NUM> in the second wall <NUM>. By moving the first rod <NUM>, the outer wall of the first rod <NUM> pushes the locating pin <NUM> to move to the second groove <NUM> of the slider <NUM>. In this case, the first rod <NUM> and the second rod <NUM> cannot be locked. When some first groove <NUM> in the first rod <NUM> directly faces the limiting hole <NUM>, the locating pin <NUM> can be located in the limiting hole <NUM> and the first groove <NUM> simultaneously. If the slider <NUM> is not pushed, the slider <NUM> is restored under the third elastic piece <NUM>, as shown in <FIG>. In this case, a bottom of the slider <NUM> abuts against the locating pin <NUM>, the locating pin <NUM> cannot be released completely from the first groove <NUM>, and the first rod <NUM> and the second rod <NUM> are locked through the locating pin <NUM>. When the locking is to be released, the slider <NUM> is pushed, such that the second groove <NUM> directly faces the limiting hole <NUM>. Through the first rod <NUM> moving axially relative to the second rod <NUM>, the locating pin <NUM> is released from the first groove <NUM> to enter the second groove <NUM>, as shown in <FIG>. In order to realize the above action, a sum of a thickness of the slider <NUM> and a diameter of the locating pin <NUM> is greater than a distance between an inner wall of the first wall <NUM> and an inner wall of the second wall <NUM>. When the slider <NUM> is attached to the first wall <NUM>, a distance between a bottom of the first groove <NUM> and the inner wall of the second wall <NUM> is not less than the diameter of the locating pin <NUM>. In order to push the slider <NUM> more conveniently, third button <NUM> can be provided on the second rod <NUM>. The third button <NUM> and the slider <NUM> are in sliding fit through an oblique plane. By pressing the third button <NUM>, the slider <NUM> can be pushed to slide. After the third button <NUM> is loosened, the third elastic piece <NUM> pushes the slider <NUM> to move reversely, thereby pushing the third button <NUM> for restoration. Through the above structure, the length of the telescopic rod is adjusted conveniently, and the telescopic rod in the locked state is stable. Therefore, the operation is more humanized.

Optionally, as shown in the figure, the support rod <NUM> includes first rod <NUM> and second rod <NUM> connected to each other. The first rod <NUM> is nested in the second rod <NUM>. Locating hole <NUM> is formed in a wall of the second rod <NUM>. A wall of the first rod <NUM> is recessed to form an accommodating groove <NUM>. Propping bead <NUM> and sixth elastic piece <NUM> are provided in the accommodating groove <NUM>. The sixth elastic piece <NUM> is provided between the propping bead <NUM> and a bottom of the accommodating groove <NUM>. Through the sixth elastic piece <NUM>, the propping bead <NUM> abuts against an inner wall of the second rod <NUM> or the locating hole <NUM>. A diameter of the locating hole <NUM> is less than a diameter of the propping bead <NUM>.

The storable fan according to the above embodiment may further includes other necessary assemblies or structures, and the corresponding arrangement positions and connection relationships may refer to structures of related apparatuses in the prior art. The connection relations, operations and working principles of the structures not mentioned above are known to those of ordinary skill in the art, and will not be described in detail herein.

Different embodiments are described progressively herein. Each embodiment focuses on the differences from other embodiments, and mutual reference may be made to the same and similar parts of such examples.

The above are only specific implementations of the present invention, such that those skilled in the art can understand or realize the present invention.
