Description
Technical field
The utility model relates to field of power tools, particularly relates to a kind of electric blower constant speed construction of switch be applied in garden instrument.
Background technology
Existing interchange on the market, direct current drive blower portions type have function of stepless speed regulation.General mode of speed regulation is divided into two kinds, and one is knob, and one is push type.
The benefit of knob can fix speed governing position when regulating the power of complete machine, do not need operator to pin switch always.Shortcoming is that operating handle is not so good as push type.
The benefit of push type is that operating handle is comfortable, and pressing stroke is darker, and complete machine power is larger, and pressing stroke is more shallow, and complete machine power is less.When shortcoming is operation, finger must pin switch always, otherwise switch plunger can automatically reset.
Utility model content
For solving the problem, the utility model provides a kind of comfortable feel, easy to operate electric blower low speed switch structure.
The technical scheme that the utility model adopts is: provide a kind of electric blower constant speed construction of switch, comprise: be assemblied in the constant speed knob on casing, speed-regulating switch and switch trigger, described switch trigger is for connecting constant speed knob and speed-regulating switch, described constant speed knob is fixed on casing by fixture, the driving lever of constant speed knob and switch trigger snapping, realize the interlock between constant speed knob and switch trigger, the first ring washer is provided with between fixture and constant speed knob, the second ring washer is provided with between fixture and casing, the damping structure with axial pressing force is provided with between fixture and the first ring washer.
In the utility model preferred embodiment, described fixture is the bolt running through constant speed knob and casing.
In the utility model preferred embodiment, described damping structure is elastic washer, wave washer or bowl-type bonded washer.
In the utility model preferred embodiment, described speed-regulating switch is push switch.
The beneficial effects of the utility model are: the utility model electric blower constant speed construction of switch adds damping structure on the switch trigger configuration of push switch, achieve constant speed function, solve push switch must pin ability speed governing always problem with finger.Pressure type speed regulating switch is made also to have constant speed regulatory function, more convenient operation.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of the utility model electric blower constant speed construction of switch one preferred embodiment;
Fig. 2 be in the constant speed of electric blower shown in Fig. 1 construction of switch A-A to cut-open view;
Fig. 3 is the stereographic map of the cut-open view shown in Fig. 2;
In accompanying drawing, the mark of each parts is as follows: 1, constant speed knob, and 2, casing, 3, speed-regulating switch, 4, switch trigger, 5, fixture, the 6, first ring washer, the 7, second ring washer, 8, damping structure.
Embodiment
Be clearly and completely described to the technical scheme in the utility model embodiment below, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
The utility model embodiment comprises:
As shown in Figure 1, a kind of electric blower constant speed construction of switch, comprising: be assemblied in the constant speed knob 1 on casing 2, speed-regulating switch 3 and switch trigger 4, and described switch trigger 4 is for connecting constant speed knob 1 and speed-regulating switch 3.
Wherein, described speed-regulating switch 3 is push switch.
As Figure 2-3, described constant speed knob 1 is fixed on casing 2 by fixture 5, and in the utility model, preferred fixture 5 is for running through the bolt of constant speed knob 1 and casing 2.
The driving lever of constant speed knob 1 and switch trigger 4 snapping, realize the interlock between constant speed knob 1 and switch trigger 4, the first ring washer 6 is provided with between bolt and constant speed knob 1, be provided with the second ring washer 7 between bolt and casing 2, between bolt and the first ring washer 6, be provided with the damping structure 8 with axial pressing force.
Described damping structure 8 Main Function is to provide rotating shaft damping, and damping structure 8 preferred elastomeric packing ring of the present utility model, also can be wave washer or bowl-type bonded washer.
The utility model utilizes damping structure 8, applies damping to constant speed knob 1, then block switch trigger 4 by the card muscle on constant speed knob 1, realizes the constant speed function of speed-regulating switch 3.
Concrete using method is:
When operator holds hair-dryer handle, with forefinger or middle finger pressing switch trigger 4, switch trigger 4 promotes speed-regulating switch 3, and complete machine starts, and now switch trigger 4 can be pressed into optional position by operator, to reach any power that it is wanted.
When operator is adjusted to suitable power, the driving lever of available thumb press constant speed knob 1, rotates to the position contacted with switch trigger 4 upper clamp bar by the card muscle on constant speed knob 1.Due to the axial pressing force of elastic washer, constant speed knob 1 is tightly pressed between the first ring washer 6 and the second ring washer 7, and the switch plunger of speed-regulating switch 3 is cannot be automatically reset.Now thumb can unclamp constant speed knob 1, and operator can carry out operation by free operant hair-dryer.
When operator's operation is complete, when needing shutdown, only need the driving lever stirring constant speed knob 1, discharged by switch trigger 4, speed-regulating switch 3 gets final product Self-resetting, machine automatic shutdown.
The utility model electric blower constant speed construction of switch adds damping structure 8 in switch trigger 4 structure of push switch, achieves constant speed function, solves push switch must pin ability speed governing always problem with finger.Pressure type speed regulating switch 3 is made also to have constant speed regulatory function, more convenient operation.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
