The specific embodiment
With reference to Fig. 1, be depicted as part three-dimensional exploded view corresponding to vacuum suction and blowing device of the present utility model, this three-dimensional exploded view has mainly shown the casing and the inner associated components thereof of this vacuum suction and blowing device, in the utility model, this vacuum suction and blowing device comprises casing 1, be fixedly installed on the handle 2 on the casing 1 and be formed on spiral case 3 on the casing 1.This casing 1 be by two to the shell combination of half mould together, the microswitch 5 that in casing 1, is provided with motor (figure does not show) and electrically connects mutually with motor.This microswitch 5 has outstanding trigger button 7 outside, and has first state and second state, and under first state, its trigger button 7 is pressed, and motor promptly is activated and drives the impeller 8 that is positioned at spiral case 3 and carry out the high speed rotary operation; And under second state, when its trigger button 7 returned to reset condition, motor was disconnected and makes impeller 8 be in the state of quitting work.Handle 2 also is to half mould, and forms switch push button 6 that 4, one of grooves have common shape and be fastened in this groove 4 and expose on the handle 2.
The cap 11 that spiral case 3 is used to accommodate impeller 8 and comprises base portion 9 and can be rotated with respect to base portion 9.Base portion 9 stretches out from the both sides of casing 1 one.By the pivot 13 between the bottom that is arranged on base portion 9 and cap 11, thereby cap 11 can be rotated with respect to base portion 11 around pivot 13 and partly exposes the impeller 8 that is positioned at spiral case 3, so that impeller 8 is cleared up.
With further reference to Fig. 2 to Fig. 3, also be provided with the flip flop equipment (not label) of switch 5 corresponding to vacuum suction and blowing device of the present utility model, this flip flop equipment comprises ejector 15 and actuating member 17 that can be matched with described ejector 15.Described ejector 15 extends towards switch 5 set directions from the bottom of described switch push button 6, and is positioned within the handle 2.This ejector 15 roughly is an arm shape, and is provided with outwards outstanding ejection surface 12 of extending and with respect to the triggering surface 14 on described ejection surface 12.This triggering surface 14 can contact with the trigger button 7 of above-mentioned switch 5.Described actuating member 17 is special screw, the acting surface 21 that it has shank of screw 16, is arranged on the cylinder head 19 of shank of screw 16 1 ends and is arranged on the other end of this shank of screw 16.This acting surface 21 has smooth sphere, and can contact with the ejection surface 12 of described ejector 15.Wherein, this shank of screw 16 is provided with in the end near acting surface 21 and has larger-diameter columniform flank 20.
With further reference to Fig. 4 to Fig. 7, in the end with respect to above-mentioned pivot 13, base portion 9 and cap 11 are respectively equipped with accepting hole 22 and 24, and these two accepting holes 22,24 are used for accommodating jointly actuating member 17.In the accepting hole 22 of base portion 9, be embedded nut 25 with the flank 20 of above-mentioned actuating member 17 tight engagement mutually.In the accepting hole 24 of cap 11, inwardly to give prominence to and be provided with a shoulder 26 with less internal diameter, this shoulder 26 has first surface 28 and second surface 27, outstanding several buckles 23 that extend on first surface 28.And Fig. 5 and Fig. 6 have shown the situation of actuating member 17 of the present utility model in a single day packing into the cap 11 of spiral case 3 promptly can not be removed, because the uniqueness of actuating member 17 of the present utility model on shape and function, it is as the base portion 9 of fixedly connected spiral case 3 and the connector of cap 11 on the one hand, on the other hand, it is again as the actuating member that triggers machine switch 5, so, arbitrarily abandoned for fear of this actuating member 17 and caused the inconvenience of using/replacing with, taked following measure: when actuating member 17 slid into the end of accepting hole 24 of cap 11, its head 19 can be kept out by the second surface 27 of shoulder 26 and interception part 17 further slides to outside the cap 11; And when attempting when accepting hole 24 is extracted actuating member 17, the flank 20 on the screw rod 16 of actuating member 17 can be by several buckle 23 cards that support on the shoulder 26, thereby have avoided actuating member 17 to be pulled out outside the accepting hole 24 and be dropped.
Like this, in use, after spiral case 3 cleans out, when actuating member 17 inserts accepting hole 22 and 24, flank 20 on it and nut 25 tight engagement mutually that is embedded in base portion 9, therefore cap 11 is fixedly connected on the base portion 9, and acting surface 21 projections of its end are outside accepting hole 22, but do not contact with the ejection surface 12 of ejector 15, and the triggering surface 14 of ejector 15 also is separated with the trigger button 7 of switch 5, as shown in Figure 2, this moment, switch 5 was in original (second) state.When needs start the machine, the pull switch push button 6 forward, make ejector disposed thereon 15 move forward, its projection ejection surface 12 outside acting surface 21 of promptly being applied part 17 carries out ejection like this, the direction that makes the triggering surface 14 of ejector 15 be provided with towards switch 5 is offset and triggers the trigger button 7 of (pressing) switch 5, and like this, switch 5 promptly is in first state, make motor be activated and drives impeller is carried out the high speed rotary operation, as shown in Figure 3.And as shown in Figure 7 and Figure 8, in case screw (actuating member) 17 is loosening mutually with the nut 25 that is embedded in base portion 9, perhaps screw 17 unloads and the cap 11 of spiral case 3 is outwarded winding so that when clearing up the impeller 8 that is arranged in the spiral case 3 from nut 25, even because carelessness, switch push button 6 is not retracted into the home position and the state that is in out, be the ejection surface 12 of ejector 15 roughly be positioned at actuating member 17 under, the acting surface 21 of actuating member 17 promptly is separated from each other with the ejection surface 12 of ejector 15, make ejector 15 return to the home position, and the trigger button 7 of switch 5 also return back to reset condition and makes impeller 8 be in the state of quitting work; Therefore, in this way, only install under the intact situation with base portion 9 at the cap 11 of spiral case 3, switch 5 just has the possibility that is triggered, thereby the potential safety hazard of having avoided switch 5 to be brought by unexpected the triggering; And the release mechanism of this switch of suction and blowing device of the present utility model only is provided with a microswitch 5 and flip flop equipment simple in structure, not only use safety, reliable, and manufacturing cost reduces.
