Unless otherwise defined, all of technologies and scientific terms used here by the article is led with the technology for belonging to the utility model
The normally understood meaning of technical staff in domain is identical.Terminology used in the description of the utility model herein only be
The purpose of description specific embodiment, it is not intended that in limitation the utility model.Term " and or " used herein includes
Any and all combinations of one or more relevant Listed Items.
Referring to FIG. 1, the utility model is related to a kind of blowers 100, including：Chassis body 110；First interface end 121,
It is arranged on chassis body 110, the first mating members can be connected with；Second interface end 122 is arranged on chassis body 110, can
It is connected with the second mating members；Control panel is arranged inside chassis body 110, and there is control blower 100 to be switched on or shut down
Start-up circuit, start-up circuit have the first safety switch 131 and the second safety switch 132, the first safety switch 131 and second peace
Full switch 132 one of them when being closed or the first safety switch 131 and when not closed the second safety switch 132, start-up circuit
It is off, blower 100 is in shutdown status；When first safety switch 131 and the second safety switch 132 are closed,
Start-up circuit is in the conduction state, and blower 100 is in and waits for open state.Wherein, first interface end 121 connects the first mating part
When part, the first safety switch 131 is closed, and when the first mating members is removed from first interface end 121, the first safety switch 131 is disconnected
It opens；When second interface end 122 connects the second mating members, the second safety switch 132 is closed, and the second mating members is from second interface
When end 122 removes, the second safety switch 132 disconnects.
Specifically, when the first component is connected to first interface end 121 or the second component is connected to second interface
When holding 122, start-up circuit is off, and blower 100 is in shutdown status at this time；When the first component is connected to
One interface end 121, and when the second component is connected to second interface end 122, start-up circuit is in the conduction state, at this time pressure-vaccum
Machine 100 is in and waits for open state.
Blower 100 further includes the motor being set in chassis body 110, is driven the fan 180 of rotation by motor and is connected
It is connected to chassis body 110 and the spiral case 170 for accommodating fan 180.Matched by the first mating members and second for connecting different
Relay part, blower 100 can realize corresponding function.
When the first safety switch 131 of above-mentioned blower 100 and one of them closure of the second safety switch 132, start electricity
Road is off, and blower 100 is in shutdown status at this time；When the first safety switch 131 and the second safety switch 132 are equal
When closure, start-up circuit is in the conduction state, and blower 100 is in and waits for open state at this time, and the first safety switch 131 and the
The closure of two safety switches 132 disconnects installation or removal by the first mating members and the second mating members to realize, thus
It realizes the first mating members and the second mating members while controlling the purpose of 100 safety switch break-make of blower.When the first mating
When any of component and the second mating members are operated, 100 autostop of blower, to avoid operator in dismounting the
The flabellum that one mating members or the second mating members touch also in operating comes to harm.
Referring to figs. 2 and 3, in one embodiment, the first mating members is blowpipe 1211, and the second mating members is shield
1221；Or first mating members be cloth bag 1212, the second mating members be suction pipe 1222.
Specifically, there are two types of operating modes when blower 100 works, respectively dry pattern and air draught pattern.Work as pressure-vaccum
When machine 100 is in blowing pattern, the first mating members that first interface end 121 connects at this time is blowpipe 1211, second interface end
Second mating members of 122 connections is shield 1221, and shield 1221 blows out 170 bottom lock of spiral case from blowpipe 1211
High-speed flow carries out the leaf for becoming scattered about ground to blow poly- heap, and blower 100 at this time can be used as hair-dryer.Work as pressure-vaccum
When machine 100 is in air draught pattern, the first mating members that first interface end 121 connects at this time is cloth bag 1212, second interface end
Second mating members of 122 connections is suction pipe 1222, and under the high speed rotation of fan 180, the inspiratory airflow of formation is in company with ground
Leaf and dust are inhaled into 1222 channel of suction pipe together from suction pipe 1222, enter collection device cloth bag by 180 processing of fan
1212, blower 100 at this time can be used as suction ventilator use.
In addition, shield 1221 can be rotatablely connected with spiral case 170, and can also be arranged between shield 1221 and spiral case 170
There is the position limiting structure that shield 1221 can be made to be maintained at opening state.In this way in air draught pattern, first it is in shield 1221 and opens
State, position-limit mechanism make shield 1221 be maintained at opening state, and second interface end 122 reconnects suction pipe 1222, is inhaled to realize
Wind function.In the above process, due to being provided with position limiting structure, operator need not use hand steered shield 1221；Meanwhile also mitigating
The mechanical injuries that dismounting shield 1221 is brought repeatedly.
Above-mentioned position limiting structure is selectable, as long as open angle between shield 1221 and spiral case 170 can be limited i.e.
It can.For example, torsional spring is arranged between shield 1221 and spiral case 170, limited according to the windup-degree of torsional spring itself, by shield 1221
It is limited in specific open angle state.In another example limited block is arranged between shield 1221 and spiral case 170, work as shield
1221 when being opened to certain angle, offsets with limited block, to be maintained at opening state.
Blower 100 realizes that the mode of blowing and two kinds of operating modes of air draught is selectable.For example, motor is using positive and negative
Rotating motor to which motor can be rotated with two kinds of just exactly opposite directions respectively, and then drives aerofoil fan or centrifugation wind
Fan is rotated with two kinds of just exactly opposite directions, for which kind of direction of rotation blower 100 to be made to realize blowing or inhale using
Wind pattern is that operator can be taking human as setting.The power drive that motor can also use others to be capable of outputting rotary power fills
Set replacement.In another example transformational structure can be arranged inside blower 100, which may be implemented the switching in air duct, from
And realize blowing and two kinds of operating modes of air draught.
