Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of Handheld fan.
Background technique
Fan, as a kind of household electric appliance, has become a kind of instrument indispensable in people's daily life.In hot summer, fan body rotates the cool breeze slowly bringing, and can play the effect of relieving summer heat, enjoying the cool.The kind of existing fan is a lot, as ceiling fan, desk fan, stand fan, air conditioning fan etc.But these fans are conventionally all heavier, mobile inconvenience.Therefore, also have some small fans that are fixed on cap to occur, but this fan is because its position is relatively fixing, can only blow to the local location of head, is not easy to multi-angle blowing.
China patent CN201448272U discloses a kind of flashlight fan, it is comprised of base, shell, fan body, rotating shaft and motor, fixedly mount in the enclosure motor, motor connection rotating shaft, provided with fan body in rotating shaft, on shell, be provided with exhaust outlet, shell is arranged on base, at shell front end, is provided with LED light emitting source, and LED light emitting source is connected on power supply by electric wire, on connection electric wire, be provided with switch, at shell front end, lampshade be set.LED light emitting source is arranged on light source fixed plate, and light source fixed plate is arranged in shell front end.
Said fans both can hand-held use, also can be placed on table top, uses more for convenience.But, when said fans is positioned over table top, the blowing angle of its fan is single non-adjustable, for example student is when doing the homework, said fans is positioned on desk top and can only blows student's chest or shoulder, can not cater to user's all kinds of demands, thereby its summer-heat removing effect is had a greatly reduced quality.
Summary of the invention
The utility model is the problems referred to above that exist for existing technology, a kind of Handheld fan is provided, technical problem to be solved in the utility model is: how by this Handheld fan can multi-angle be dried, thereby can cater to user's different demands.
The purpose of this utility model can realize by following technical proposal:
A kind of Handheld fan, described fan comprises fan body, holding rod and base, described fan body is fixed on holding rod, it is characterized in that, described fan also comprises link, described holding rod and link removably connect, and described link and described base are hinged and both mutual pitch rotation, and between this link and base, are also provided with and can make both relatively-stationary position structures.
Its working principle is as follows: the fan body of indication in the application, refer to the wind regime integral body that flabellum, square and motor form, and this part is prior art, not in this to go forth.And the application's innovative point is, the holding rod and the link that are provided with fan body removably connect, and this Handheld fan both can grasp holding rod use, can make again holding rod be connected with link, make it be used as desk fan and use; This is because link and base are hinged, can swing by the relative base of link, regulate the blowing angle of fan body, make it cater to user's different demands, to be regulated complete, by position structure, make link relative with base fixing again, thereby make this fan can keep the blowing angle of the most comfortable.
In above-mentioned a kind of Handheld fan, described link comprises cylindrical shell one and cylindrical shell two, the cylinder end of the cylinder end of described cylindrical shell one and cylindrical shell two, is connected as a single entity, one end of described holding rod is plugged in described cylindrical shell one, on described cylindrical shell two, be connected with a rotating shaft, the two ends of described rotating shaft are rotated and are arranged on described base.Cylindrical shell two is hinged by rotating shaft and base, thereby makes holding rod base swing relatively.
In above-mentioned a kind of Handheld fan, described base comprises pedestal and cover plate, the inner plate surface of described cover plate is connected with described pedestal, the outer plate surface of described cover plate is fixed with two mounting blocks, two mounting blocks intervals arrange, on described mounting blocks, all offer a blind hole, rotate respectively in the blind hole that is arranged at two mounting blocks at the two ends of described rotating shaft.The Placement of cover plate inner plate surface and pedestal, can fix by fastening piece, also can realize by the mode of clamping both fixing and all can.
In above-mentioned a kind of Handheld fan, described rotating shaft comprises a connecting rod and two plectanes, described plectane rotates and is arranged in described blind hole, the two ends of described connecting rod are individually fixed in the circle centre position of two plectanes, the sidewall of described connecting rod is fixed with connecting base, on described connecting base, offer tapped hole, described link also comprise run through one of described cylindrical shell at the bottom of and the through hole at the bottom of two of cylindrical shells, in described tapped hole and through hole, be plugged with fastening piece, described cylindrical shell two is sheathed on described connecting base simultaneously.Because frequent rotation between rotating shaft and blind hole can produce fretting wear, after rotating shaft damages, only need to change separately rotating shaft, can not need to change whole link; Fastening piece in the application can be bolt, screw etc.
In above-mentioned a kind of Handheld fan, as a kind of scheme, on the hole wall of described blind hole, offer annular groove one, on the outer circumferential face of described plectane, offer annular groove two, described position structure comprises damped ring, the inner peripheral surface of described damped ring is embedded in described annular groove two, and the outer circumferential face of described damped ring is embedded in described annular groove one.Plectane is realized the relative fixing of rotating shaft and blind hole by damped ring with the frictional force between annular groove one, thereby can be relative with base fixing after making link be rocked to expection angle, simultaneously, when user swings link with hand, external force is greater than the frictional force between damped ring and annular groove two, makes link can relatively swing with base.
In above-mentioned a kind of Handheld fan, the power supply that is fixed with LED lamp on described holding rod and is electrically connected to this LED lamp, is also fixed with the switch that can control described LED lamp light and shade on described holding rod.Be designed with after LED lamp, make this fan have the function of flashlight concurrently.
In above-mentioned a kind of Handheld fan, on the sidewall of described cylindrical shell one, offer an opening, on the sidewall of described holding rod, be provided with charging indicator light and charging jack, when one end of described holding rod is plugged in cylindrical shell one when interior, described charging indicator light and charging jack are aimed at described opening.Be designed with after charging indicator light and charging jack, conveniently fan charged in time; And on cylindrical shell one, be designed with opening, be for one end of holding rod is plugged in cylindrical shell one interior after, fan can be positioned on table top by base, and now charging indicator light is stated opening with charging jack aligning, user can be plugged in power line in charging jack by opening, convenient to operation, the Placement Problems while having solved fan charging.
Compared with prior art, the utlity model has following advantage:
1, can swing by the relative base of link, regulate the blowing angle of fan body, make its different demands of catering to user, to be regulated complete, then make link relative with base fixing by position structure, thus make this fan can keep the blowing angle of the most comfortable;
2, after rotating shaft damages, only need to change separately rotating shaft, can not need to change whole link;
3, one end of holding rod is plugged in cylindrical shell one interior after, fan can be positioned on table top by base, and now charging indicator light is stated opening with charging jack aligning, and user can be plugged in power line in charging jack by opening, convenient to operation, the Placement Problems while having solved fan charging.
