Description
Technical field
The present invention relates to family's electro-technical field more particularly to a kind of electric fans for preventing children's injury.
Background technique
Electric fan can bring one of essential electric appliance of nice and cool and family to us.Child has seen electric fan perhaps ten
Point curiosity, in surprise in the cool breeze for being fanned out to the whirling come in electric fan, more allow child is fascinated in fact is that electric fan turns not stop for they
Blade.Its genuine child perceives electric fan often through tactile, and then thus many accidents have occurred.So as monitoring
The parent of people, cannot when monitor child, therefore will appear the news that child is hurt by electric fan often.
Occurs a kind of bladeless fan in the market, by the way that blade in pedestal, is sucked air again from above from bottom
Annulus slit in produce by boasting, still, under the premise of blowing out equal air quantity, flabellum cross section is bigger, and required revolving speed is just
Lower, noise is also just smaller.And the pedestal of bladeless fan determines that its internal flabellum diameter is usually all smaller, so wanting
Reaching air quantity same as conventional fan just must allow small fan blade rotating to obtain faster, thus the noise generated is also just necessarily bigger, though
The hand that so can be avoided child is hurt by fan, but expensive, and biggish noise is unfavorable for the routine use of family.
Summary of the invention
The present invention aiming at the shortcomings in the prior art, provide it is a kind of can effectively shift child's attention, what is made it away from is anti-
The only electric fan of children's injury, is effectively ensured the safety of child while not stopping working.
In order to solve the above-mentioned technical problem, the present invention is addressed by following technical proposals: one kind prevents children injured
Electric fan, including fan head and the blower tray connecting with fan head, the fan head includes horn-like wind scooper, be located at institute
It states and is provided with the internal fan base with cavity between fan head and blower tray, the cavity includes motor cavity and is located at motor cavity
The alarm chamber of two sides, the alarm is intracavitary to be provided with toy ball, and the resistance that toy ball is arranged by the blower tray two sides
The pressure sensor of structure and top of chamber of alarming is kept off against the alarm chamber outside is provided with the bullet being fixedly connected with blower tray
Spring is provided with range sensor on the wind scooper and fan base.
In above scheme, it is preferred that the alarm chamber includes the first alarm chamber and the second alarm for being provided with alarm
Chamber cooperates internal toy ball to realize transfer child attention, while starting alarm, to attract prison by setting alarm chamber
Shield personnel reach position of fan in time, avoid the injury that child is subject to by curiosity.
In above scheme, it is preferred that the barrier structure includes the bumping post fixed with blower tray and respectively with first
The big baffle of alarm chamber and the second alarm bottom of chamber portion alarm chamber small front apron cooperation, when realizing the placement and starting alarm of toy ball
Toy ball drops out automatically.
In above scheme, it is preferred that the big baffle and bumping post are rotatablely connected, and the internal toy ball that is conducive to fail is played
Function.
In above scheme, it is preferred that the alarm chamber small front apron and chamber cavity of alarming is rotation connections.
In above scheme, it is preferred that be provided with first distance sensor on the wind scooper.
In above scheme, it is preferred that be provided with second distance sensor on the fan base, pass through two range sensors
While be arranged, it is corresponding effectively whether to need to make alarm by height resolution.
In above scheme, it is preferred that the blower tray can hand-operated lifting, can unrestricted choice fan height.
In order to solve the above-mentioned technical problem, the present invention is addressed by following technical proposals:, can by above structure
It realizes when children are close to fan, is risen by fan head and fan base is pulled to rise, by the cooperation of baffle, realize that chamber is intracorporal
Ball abjection, shifts child attention, while sounding an alarm to adult, and adult is reminded to return to child as early as possible at one's side, to realize to youngster
Virgin monitoring, the work without interrupting electric fan.
Detailed description of the invention
Fig. 1, schematic structural view of the invention.
Fig. 2, lateral structure schematic diagram.
Specific embodiment
Present invention will be further explained below with reference to the attached drawings and examples.
Referring to Fig. 1 to Fig. 2, a kind of electric fan preventing children's injury, including fan head and the fan being connect with fan head
Bracket 2, the fan head front end are provided with horn-like wind scooper 1, are provided with inside between the fan head and blower tray 2
Fan base 3 with cavity, the cavity include motor cavity 31 and the alarm chamber positioned at 31 two sides of motor cavity, the motor cavity 31
The push rod 311 of interior setting is connect with fan head bracket, and the alarm is intracavitary to be provided with toy ball 33, and toy ball 33 passes through institute
The barrier structure of 2 two sides of blower tray setting and the pressure sensor 34 of alarm top of chamber are stated against the alarm bottom of chamber portion is set
It is equipped with the alarm chamber small front apron 32 connecting with the spring 35 on blower tray 2, is provided on the wind scooper 1 and fan base 3
Range sensor.
The alarm chamber includes the first alarm chamber 321 and the second alarm chamber 322 for being provided with alarm, the blocking junction
Structure includes the bumping post 51 and respectively with first alarm chamber 321 and second alarm chamber 322 bottom alarm chamber fixed with blower tray 2
The big baffle 52 that small front apron 32 cooperates, the big baffle 52 are rotatablely connected with bumping post 51, the alarm chamber small front apron 32 and alarm
Chamber cavity is rotation connection, is provided with first distance sensor 41 on the wind scooper 1, is provided with second on the fan base 3
Range sensor 42, the blower tray 2 can hand-operated lifting.
During fan works normally, when children are close to fan, second distance sensor 42 incudes, at this point, in motor cavity 31
The push rod 311 of setting pushes fan head bracket to rise, while entire fan base 3 being driven to rise, and in uphill process, spring 35 can be drawn
Dynamic alarm chamber small front apron 32, rotates it counterclockwise, relies on the big baffle 52 on alarm chamber small front apron 32 because of alarm
Chamber small front apron 32 is not hooked a little after rotating down, and because the weight of toy ball 33 is pressing against big baffle 52 and turning clockwise
Dynamic, toy ball 33 is fallen from bottom opening at this time, thus attract child attention, after toy ball 33 is fallen, pressure sensor
34 inductions, intracavitary alarm equipment alarm of alarming remind adult to return to child as early as possible at one's side, to realize the custody of children.
When adult close to when, first sensor 41 and second distance sensor 42 incude simultaneously, are arranged in motor cavity 31
Push rod 311 is failure to actuate, and false alarm is prevented.
Protection scope of the present invention includes but is not limited to embodiment of above, and protection scope of the present invention is with claims
