Detailed Description

The embodiments of the present invention will be further explained with reference to the accompanying drawings:

as shown in fig. 1 and fig. 2-4, a wearable fan comprises a watchband 1 and a watchcase 2, a fan blade 3 is arranged above the watchcase 2, a control switch 4 is arranged on the watchcase 2, a power source 5 is arranged in the watchcase 2, the power source 5 is connected with the fan blade 3 through a transmission shaft 51, the control switch 4 is electrically connected with the power source 5, the watchcase 2 is arranged in the middle of the watchband 1, and the watchband 1 has a first state of straightening and a second state of being automatically deformed under stress for wearing. The beneficial effects of the utility model are that, can help often give the breeze outside the person of business trip or tourism, can use anytime and anywhere, very convenient and practical. Meanwhile, the watch band can be worn on the wrist quickly for use, hands are liberated, normal work and study of the hands are not influenced, the watch band is particularly suitable for being used by groups such as students, and the watch band has the advantages of attractiveness, practicability, strong interestingness and the like. The utility model discloses simple structure still has, convenient assembling, and the action is reliable, advantages such as long service life.

The bracelet 1 is bent towards the case 2 and forms a groove 11 when it is in the first state. Specifically speaking, the watchband 1 comprises a deformation layer and a protective layer, wherein the protective layer is coated outside the deformation layer. More specifically, the deformation layer adopt spring steel integrated into one piece, the protective layer adopt silica gel integrated into one piece. The structure ensures that the state of the watchband is switched conveniently, reliably and quickly, and the watchband is interesting. Simultaneously the setting on deformation layer is convenient for the watchband quick deformation, is convenient for switch over the state of watchband fast, and the user that the setting of protective layer can not harm wears the portion (usually the wrist), and is more comfortable.

The utility model discloses still include connecting piece 21, connecting piece 21 be fixed in the bottom of watchcase and mutually support with watchcase 2 and form mounting hole 22, watchband 1 pass mounting hole 22 and can dismantle with watchcase 2 and be connected. Specifically, the connecting piece and the base are of an integrated structure. More specifically, the watchband 1 is provided with a notch groove 12, and the connecting piece 21 is arranged in the notch groove 12 and spaced from the side wall of the notch groove 12. Such structure is convenient for block the watchband through the cooperation of breach groove and connecting piece, and again can be very convenient quick when needs dismouting watchband, and more specifically says so, the breach groove of watchband slightly is greater than the width of connecting piece to make the watchband have certain activity allowance in connecting piece department, the dismouting watchband of being convenient for.

The electronic watch is characterized in that a control circuit board 6 is arranged in the watch case 2, a USB interface 7 is arranged on the control circuit board 6, the USB interface 7 extends out of the watch case 2, the control switch 4 is electrically connected with the control circuit board 6, and the control circuit board 6 is electrically connected with the power source 5. The structure facilitates control of the control circuit board, and specific circuits related between the control switch and the control circuit board, between the USB interface and the control circuit board, and between the control circuit board and the power source can be realized by adopting the prior art, which is not described herein again. Therefore, the power source can be reliably driven to act through the control switch, the structure is simple, and the control is convenient and reliable.

The watch case 2 comprises an upper cover 23 and a base 24, the upper cover 23 and the base 24 are in interference fit, a baffle 25 and a supporting plate 26 used for placing the control circuit board 6 are arranged on the base 24, and the baffle 25 and the inner wall of the base 24 are mutually matched to form an accommodating space 27 used for accommodating the control circuit board 6. The structure can reliably limit the control circuit board, so that the control circuit board is fixed and reliable. Specific theory, the baffle is the setting of L type, avoids the control scheme board to rock through the right angle is spacing promptly, and the height that highly is less than the baffle of backup pad can play very big limiting displacement simultaneously again, and the backup pad also can provide the air current circulation space for the heat dissipation of control scheme board, simple structure, and is fixed reliable.

The base 24 on be equipped with polylith limiting plate 28, polylith limiting plate 28 is located the power supply 5 outside and is mutually supported and carry on spacingly to power supply 5, upper cover 23 on be equipped with the mounting groove 29 with power supply 5 surface looks adaptation. Specifically, the watch case 2 is square, star-shaped or heart-shaped, the watch case 2 is injection molded by using an ABS material, and the ABS is an acronym of Acrylonitrile Butadiene Styrene, which means that an Acrylonitrile-Butadiene-Styrene copolymer is a thermoplastic high polymer structure material with high strength, good toughness and easy processing and molding, and is also called as ABS resin. The fan blades 3 are two, three or four, and the fan blades 3 are integrally formed by silica gel. Such structure makes the power supply fixed reliable, and it is spacing that the limiting plate is passed through to the power supply bottom, and it is spacing that the mounting groove is passed through on upper portion, avoids rocking for flabellum work is more stable.
