Description

A kind of fan
Technical field
The present invention relates to consumer goods industries, more specifically, being related to a kind of fan.
Background technique
Fan mainly passes through makes air accelerate circulation using the rotation of motor driven fan leaf, and then reaches cooling and heatstroke-eliminating With the purpose of ventilating air.Existing fan volume is all bigger, it has not been convenient to carry, operation is more complicated, is not fixed firmly, no It is able to satisfy the requirement of people, for ease of use, gradually develops some mini fans, these mini fans can To make people hand held, it is salubrious that fan bring is enjoyed whenever and wherever possible.
Summary of the invention
Stronger fan is fixed technical problem to be solved by the invention is to provide a kind of.
The purpose of the present invention is achieved through the following technical solutions:
A kind of fan, the fan include shell and support rod, and the shell is equipped with fasteners, and the fasteners are to institute It states supporting rod clamp to fasten, the inner surface of the fasteners is equipped with fastening protrusion, and the fastening protrusion is outer with the support rod Surface is oppositely arranged.
The fasteners include cambered surface portion, and the fastening protrusion is located in the cambered surface portion, the cambered surface portion and the branch The outer surface of strut matches, and the cross section in the cambered surface portion is the shape of semi arch, and the support rod is cylindrical setting.This The setting of sample, cambered surface portion can preferably be fixed support rod, preferably can adjust arc according to the radian of support rod The radian of face, is bonded cambered surface portion preferably with the support rod, can thus fix support rod It is more firm, fasten the better of protrusion and support rod be clamped, it is very effective increase fasteners and support rod it Between frictional force so that support rod is not allowed more to be drawn out easily, so that fan is more durable;Cylindrical support rod can With the bending of more convenient support rod, so that the bending of support rod is more easily laborsaving, cambered surface portion can also preferably cooperate Support rod is clamped.
The cambered surface portion is equipped with limit and encloses bone, and the shell is equipped with the fixing groove that bone photo cooperation is enclosed with the limit, The limit is enclosed bone and is radially extended along the cambered surface portion, and the limit encloses bone equipped with lightening recesses.In this way, limit is enclosed bone and is consolidated Determine the good cooperation of slot, fasteners are firmly fixed on shell very much, to preferably consolidate to support rod Fixed, limit encloses bone and extend along cambered surface portion, preferably can carry out installation fixation to fasteners in this way, while facilitating make-up Tight part is dismantled;The setting of lightening recesses can be very good to reduce the weight of fasteners, so that prevailing custom enhanced convenience carries, It also can be good at saving consumptive material simultaneously, further decrease production cost.
The cambered surface portion encloses bone fixation with the limit and connect or be integrally formed, and the fastening protrusion and the fasteners are solid Fixed connection is integrally formed.In this way, the processing and production of very convenient fasteners, facilitate the depanning of fasteners, so that fasteners Production cost further decrease, integrally formed setting but also the installation and removal enhanced convenience of fasteners is simple, into One step saves human cost, so that the production cost of fan further decreases, to improve the market competitiveness well.
Cavity is equipped in the shell, the cavity is equipped with top cover, and the top cover can carry out lid conjunction, institute to the cavity State that support rod is flexible to be placed in the cavity.In this way, the setting of cavity, is bent support rod very easily and puts It sets in cavity, support rod is stored so as to extraordinary, top cover lid is closed on cavity, it is very effective to sky Intracavitary portion is covered, and prevents dust or droplet etc. from dropping into cavity inside, the very effective normal work that ensure that fan; When fan when not in use, support rod bending is received into cavity, the pendulum that fan can become desktop is adornd, by support rod from cavity It inside takes out in use, cavity can be used as to pen container or card holder use, so that fan is very practical.
The first plate washer and second baffle are equipped in the cavity, first plate washer and the second baffle are symmetrical arranged, Cap recess is designed on first plate washer and the second baffle.It, can be in this way, the setting of the first plate washer and second baffle Cavity is reinforced well, so that the inner wall of cavity is more secured, so as to well to the portion stored in cavity Part is protected;And first plate washer and second baffle can be very good to be split the inner space of shell, better benefit With the space of enclosure interior, while the first plate washer and second baffle can be very good to cover internal wiring, so that cavity Inside seems very neat and artistic;The setting of cap recess so that the installation of top cover is very convenient laborsaving so that The use of fan is more convenient.
Top cover slot, the top cover slot and the cap recess are designed on the first baffle and the second baffle It is arranged at right angle.In this way, the storage and placement of the very convenient top cover of setting of top cover slot, when top cover is extracted from cap recess Afterwards, top cover can be inserted into top cover slot, extraordinary can realize the fixed storage of top cover in this way, it can be with extraordinary anti- The only loss of top cover, to guarantee the durability of top cover, and top cover is inserted into top cover slot, can space to cavity into Row segmentation well, can use and used using cavity as pen container or card holder, accomplish that the multifunction of fan uses.
One end of the support rod is connected with motor, and the other end of the support rod is connected with power supply, the support Hollow portion is equipped in bar, the connecting line between the power supply and the motor passes through the hollow portion.In this way, can by support rod Motor to be connected to power supply well, the arrangement of very convenient route, while support rod is also extraordinary protects to route Shield, so that the appearance of fan is more simple and beautiful.
The shell includes power storehouse, and the power supply is located in the power storehouse, between the power storehouse and the cavity Equipped with partition protrusion.Cavity and power storehouse are split in this way, partition protrusion is extraordinary, allow cavity preferably interior It utilizes, and can be very good to protect power storehouse, so that the power supply in power storehouse can be very good to be protected, to make Obtaining fan can very good efficient operating.
The shell is equipped with open tubular column, and the open tubular column extends in the power storehouse, the open tubular column and the electricity Source storehouse is connected, and is additionally provided with that bone is enclosed in switch limit and bone is enclosed in interface limit on the shell, and the switch, which limits, encloses bone and described Interface limit encloses bone and is connected with the power storehouse.In this way, the setting of open tubular column well protects route, pass through support The open tubular column that is routed through of bar is connected with power storehouse, while making the arrangement of route very simple and beautiful;Switch limit is enclosed Bone and interface limit enclose bone and are connected with power storehouse, can preferably be routed, so that the arrangement of route is very simple and convenient.
The present invention is due to the structure using fasteners, so that the fixation of support rod is very convenient simple, and fasteners Extraordinary supporting rod clamp can be fastened, while the installation and removal of fasteners and support rod are very convenient, be fastened convex Act the inner surface for being located at fasteners, the very effective frictional force increased between fasteners and support rod, so as to support rod Fixation it is more firm, support rod be free to bending deformation, so that fan is more durable.
