Description

The fan structure of automatic take-up

Technical field

The utility model relates to a kind of fan structure of automatic take-up, refers to a kind of structure of electric fan especially, is to improve power line can't collect the shortcoming that receipts produce, and utilizes the setting of the inner auto take-up of electric fan, makes this fan structure have more practicability.

Background technique

Electric fan is the very general electrical appliance of daily life, also is common in the each household family or factory building, is weather when hotter, is beneficial to the electrical appliance of use.And present existing fan structure, its power line all is to be extended by the fan main body control end to expose to outside the electric fan main body, there is no provides the space that can take in power line, when not using fan, custom is wound in power line on the electric fan main body, this kind canoe makes power line be entangled with mutually easily, cause power line to be difficult for untiing when reusing, when winding is certain, this power line comes off from fan main body again easily, and must do the action of winding once more, when reusing this electric fan, the power line that must will be wound in fan main body is untied, need the more time of cost, and power plug is not when being inserted on the socket, it exposes to the outer power line collection of fan main body and receives trouble, also can only be positioned on the ground or be wound on the fan main body, make usage space be full of mixed and disorderly power line, indoor occupant is tripped by mixed and disorderly power line easily, and power line can't neatly be fastened on fan main body, cause an inconvenience of using, and destroy the overall appearance of usage space.

The above-mentioned existing structure of detailed sight is not difficult to realize its shortcoming part, and main cause is as follows:

One, existing fan structure, its power line is to be extended by the fan main body control device to expose to outside the fan main body, and not having provides the placement that can take in power line, under obsolete state, can't the power cord accommodation that expose is neat, can only be wound on the fan main body, power line is intertwined easily, during order use next time, form the puzzlement that is difficult for untiing, need spend the more time and twine power line, and when winding is certain, this power line comes off from fan main body easily, and formation one must be done the action of winding, the inconvenience that causes the user to use once more.

Two, when fan does not use, this exposes to the outer power line of fan main body foldable space is not provided, can only directly be wound in power line on the fan main body or be positioned on the floor, the personnel that cause are easily tripped by power line, or be that situation about when fan uses power plug being kicked off from socket takes place, and makes the danger of this usage space increase.

In view of this, the inventor is in line with the manufacturing development of being engaged in Related product for many years and design experiences, at above-mentioned target, in detail after design and the scrupulous assessment, eventually the utility model of a true tool practicability.

The technology point of desiring to deal with problems:

Existing fan structure, its power line is to expose to the fan main body outside, and do not provide the placement that can make things convenient for power cord accommodation, when not in use, take in for convenience, power line can only be wound on the fan main body, power line is intertwined mutually easily, when reusing, formation is difficult for the puzzlement of untiing, and when using this fan, this exposes to the outer power line of fan main body and is to form a mixed and disorderly phenomenon on the usage space, and the personnel that form are easily tripped by power line or the situation that power plug is kicked off is taken place, and this is the technical problem for the solution of the utility model desire.

The model utility content

The purpose of this utility model provides a kind of automatic take-up fan structure, it includes: a fan main body and a Take up unit, this Take up unit is installed on the position of fan main body inside, the elastic component of its Take up unit is sheathed in the groove that is pivoted of rotary seat, and the outer binding end of elastic component fixed with the notch inlay card that combines of rotary seat outer periphery, and the center-side installing of elastic component is fixed in the lid fixed end draw-in groove, and the hole that is pivoted of rotary seat is arranged on the fixed end, the fixed end institute inlay card of the fixedly notch of its rotary seat peripheral region opposite side and lead is fixed, and lead curled up the peripheral region of being located at rotary seat, again a base is combined with lid, and the holding flange of base and the fixed end of lid are fixed, and the power plug of lead is limited to the lid open outer end, and exposes to the fan main body outside by perforating.

The beneficial effects of the utility model are:

One, the inner set Take up unit of this fan main body, when using this electric fan, the power socket that power plug is desired to plug backward stretches, when making lead be the fan user mode, the length that may command lead desire is used, the length that can not produce the lead use is long, and the situation that personnel are tripped takes place, and makes this fan main body have more practicability in use.

When two, not using fan, can furl by the Take up unit of inside and reply this power lead, the lead of this fan main body need not be wrapped on the fan main body again, or be positioned on the ground, make more neat appearance of indoor usage space.
