Description
Technical field
The present invention relates to household appliance technical field, in particular, relate to a kind of micro fan.
Background technique
Fan in the market mainly comprises ceiling fan and stand fan, and ceiling fan does not generally have flabellum protection cover, and stand fan has flabellum protection cover substantially, thereby avoids hurting the user.In order to satisfy people's demand, some portable micro fans occur in market, and these micro fans are smaller mostly, mainly comprise housing and are arranged on the interior motor of housing and flabellum etc., and be built-in with battery or chargeable battery, thereby be convenient for carrying and use.
I have designed a kind of micro fan, comprise that integral body is the housing of automotive wheel structure, is installed in motor, rechargeable battery in the housing, is used for charging inlet and the power control switch of charging and is arranged on the flabellum of being made by soft material of outside and is used for the fixedly fixed block of flabellum, fixed block closely is connected cooperation with the output terminal of motor, thereby revolution drives fixed block and rotates, and then drives the flabellum rotation.Described housing comprises first placement section and second placement section that connects by link, and housing comprises that described first placement section comprises first standing groove that is arranged on the fore shell place and second standing groove that is arranged on the back cover place by screw fixing fore shell and back cover; Described second placement section comprises first groove that is arranged on the fore shell place and second groove that is arranged on the back cover place, and described power control switch is bonded in second standing groove by glue.Housing is outer not to have any stopping owing to flabellum is arranged on, thereby has just avoided the waste of air quantity, and then has increased wind-force; In addition, described flabellum is that soft material is made, and can not damage it even the user runs into also.This scheme is unexposed.
But, because power control switch is adhesively fixed in second standing groove of back cover by glue, in case might make glue bonding ineffective when in use power control switch is subjected to bigger pressure, thereby cause power control switch loosening, and then make it can't proper functioning.
Summary of the invention
Technical problem to be solved by this invention provides a kind of micro fan of power control switch fixation.
The objective of the invention is to be achieved through the following technical solutions: a kind of micro fan, comprise back cover, described back cover is provided with for second standing groove of placing power control switch, and described back cover is provided with the fixing device for the fixed power source control switch in second standing groove.
Preferably, described fixing device comprises limited post, power control switch be provided with join with described limited post and spacing hole.When power control switch was placed in second standing groove, limited post was inserted in the spacing hole, and power control switch is played position-limiting action, thereby prevented from moving, being convenient to fix.
Preferably, described spacing hole is two, lays respectively at the two ends of power control switch.Corresponding limited post also arranges two, and cooperates the position of spacing hole to arrange, thereby two spacing holes and two limited posts cooperate, and just can prevent that power control switch from moving.
Preferably, described fixing device also comprises two parts that are relatively fixed that are arranged in second standing groove, is relatively fixed between the part at two in the time of in power control switch is placed into second standing groove.Fixed block is arranged in second standing groove, carry out in the both sides of power control switch spacing, thereby four faces around the power control switch are all limited, so conveniently and solidly power control switch are fixed in second standing groove.
Preferably, the height of described fixed block is higher than power control switch at fixed block and partly is provided be used to the buckle that blocks power control switch greater than the placement height of power control switch.Fixed block top arranges the both sides that buckle is stuck in power control switch, thereby has just fixed power control switch.
Preferably, described buckle is projection outstanding in opposite directions on the fixed block, and described projection broadens from top to bottom gradually.Buckle is set like this makes things convenient for power control switch to be placed between the fixed block, power control switch is pressed downwards from the projection top, fixed block is plastic materials, make and have certain elasticity because fixed block is plastic materials, thereby when power control switch is placed between the fixed block when being blocked by buckle, fixed block recovers original form.
Preferably, described limited post is cylindrical body, and described spacing hole is circular.The convenient cooperation and production is set like this.
Preferably, described fixed block is cuboid.The cuboid fixed-area is big.
Preferably, described power control switch also is bonded in first groove by glue.Increase fixing soundness.
Preferably, described power control switch comprises a pushing switch, and described back cover arranges one for the through hole of placing pushing switch at first groove middle part, and an outward extending convex edge is set around the described through hole.The convex edge plays a protective role to pushing switch, especially in the process of carrying, prevents that pushing switch from contacting impaired with other object or be opened.
The present invention is owing to be provided for placing second standing groove of power control switch at the back cover middle part, and in second standing groove, be provided with fixing device for the fixed power source control switch, be to be bonded in the back cover by glue before the power control switch, glue may be ineffective when being subjected to bigger extruding; Fixing device is set now at first carries out spacing and fixing to power control switch, and then it is bonding by glue, since fixing device power control switch is carried out spacing, meeting contacts with power control switch fixedly the time, thereby also can increase the bonding area of glue when bonding by glue again, not only fixing device has been carried out spacingly, fixing to power control switch, and glue is fixing also more firm.
