Referring now to Fig. 3.Blast pipe 35 is pulled down from fuselage 20 at this moment, and therefore air blast joint 36 is now exposed.Because air blast joint 36 itself has openend (being the openend of its inner air pipeline), therefore, at air blast vacuum cleaner, during now in dust suction pattern, outside air enters fuselage through dust suction sleeve pipe 33 and dust absorption adapter connector (not shown) successively along the indicated direction of arrow 100.The air of discharging enters dust bag along the direction shown in arrow 104 on the other hand.This dust bag comprises first bag of part 37 and second bag of part 38.Wherein second bag of part 38 be filtered for the air of collecting air blast vacuum cleaner and containing dust in suction after remaining dust, and that the material of first bag of part 37 is air is transparent, arrive extraneous thereby the air in first bag of part 37 can penetrate its bag of material.Therefore, first air enters second bag of part 38 recited above, and the dust object of carrying secretly in air etc. will be deposited on the bottom of second bag of part 38, and remaining air will continue to first bag of part 37, and penetrate into ambient atmosphere from the bag wall of first bag of part 37.
Fig. 4 is the stereogram of the air blast vacuum cleaner of Fig. 1, and it is in dust suction pattern.For the sake of simplicity, in Fig. 4, there is not the dust bag that air blast vacuum cleaner is shown.Air blast vacuum cleaner has safe locking mechanism 40, and it prevents that user from unexpectedly accessing the impeller/blower fan in High Rotation Speed in the operating process of air blast vacuum cleaner.The detailed structure of this safe locking mechanism and operation will be in following descriptions.
Fig. 5 A and Fig. 5 B illustrate the structure of the air blast vacuum cleaner safe locking mechanism 40 of Fig. 4.Particularly, safe locking mechanism 40 is arranged on dust bag 37,38 and the interface between the fuselage 20 of impeller/blower fan is wherein installed.As shown in Fig. 5 A and Fig. 5 B, safe locking mechanism 40 is by mode conversion switch 22, is arranged on circular lockplate 42 on fuselage 20 and dust bag joint 44 Group of dust bag 37,38 (not shown) and becomes.In this embodiment, mode conversion switch 22 can rotate around the pivot X being formed on fuselage 20, and have in its one end away from pivot for coordinating the bar shaped portion 46 of circular lockplate 42, for holding the groove 50 of at least part of circular lockplate 42 and for mode conversion switch 22 being locked onto to the outstanding auxiliary section 48 of circular lockplate 42.Circular lockplate 42 is suitable for rotating around pivot Y, and has and be formed with multiple outstanding auxiliary sections 52 on its surface, and multiple form in its circumferential edge by the head elements 54 of spring 62 radial offset (Fig. 5 C illustrates in more detail).Dust bag joint 44 comprises the bar shaped portion 70 for coordinating circular lockplate 42, for receiving the insert port 56 of described fuselage 20, for holding the groove 58 of at least part of circular lockplate 42, and for dust bag joint 44 (and therefore dust bag 37,38) being locked onto to the outstanding auxiliary section 60 of circular lockplate 42.In addition, fuselage 20 is provided with the wheel rim 66 for joining with the edge 64 of dust bag joint 44.
In the utility model, mode conversion switch 22 is arranged on dust bag 37 for handling one, 38 and fuselage 20 between the outlet air air deflector (not shown) in pipe outlet hole, switch between outlet opening closed position (air blast mode of operation) and outlet opening open position (dust suction mode of operation) so that must export air deflector, wherein in the time of outlet opening closed position, match with locking mode change-over switch 22 in the outstanding auxiliary section 48 of mode conversion switch 22 and the outstanding auxiliary section 52 of circular lockplate 42, and in the time of outlet opening open position, dust bag joint is matched to lock in the outstanding auxiliary section 60 of dust bag joint 44 and the outstanding auxiliary section 52 of circular lockplate 42.
Fig. 6 A to Fig. 8 illustrates when air blast vacuum cleaner is switched to dust suction mode of operation by air blast mode of operation, the operation of air blast vacuum cleaner safe locking mechanism 40.
Fig. 6 A and Fig. 6 B illustrate that the mode conversion switch of air blast vacuum cleaner safe locking mechanism 40 is in the lock state and dust bag joint 44 is not connected to air blast vacuum cleaner fuselage 20.In Fig. 6 A and Fig. 6 B, air blast vacuum cleaner is in air blast mode of operation.The outstanding auxiliary section 48 of mode conversion switch 22 is near the outstanding auxiliary section 52a of circular lockplate 42.Thus, mode conversion switch 22 locks with circular lockplate 42, and user is actuation patterns change-over switch 22 directly, and the pipe outlet hole of fuselage 20 that leads to impeller/blower fan is also because outlet air air deflector is closed in outlet opening closed position.
By dust bag being connected to the air blast vacuum cleaner shown in Fig. 6 A and Fig. 6 B, can obtain Fig. 7 A and Fig. 7 B and illustrate the configuration of air blast vacuum cleaner safe locking mechanism 40, wherein mode conversion switch 22 is in released state and dust bag joint 44 is in the lock state.In Fig. 7 A to Fig. 7 B, air blast vacuum cleaner is just switched to dust suction mode of operation from air blast mode of operation.In this process, first the bar shaped portion 70 of dust bag joint 44 promotes head elements 54a so that circular lockplate 42 is rotated around pivot Y, and the locking between the outstanding auxiliary section 48 of off mode change-over switch 22 and the outstanding auxiliary section 52a of circular lockplate 42 thus.Meanwhile, another outstanding auxiliary section 52b of circular lockplate 42 with the outstanding auxiliary section 60 of dust bag joint 44 near coordinating.Thus, dust bag joint 44 locks with circular lockplate 42.Like this, user can not directly remove dust bag 37,38 (not shown), thus lead to impeller/blower fan fuselage 20 pipe outlet hole be again closed.
Fig. 8 illustrates the situation that moves apart circular lockplate 42 after mode conversion switch 22 is unlocked.Now, outlet air air deflector is in outlet opening open position.As shown in Figure 8, mode conversion switch 22 is activated by user and rotates around the pivot X being formed on fuselage 20, thereby activates the dust suction mode of operation of air blast vacuum cleaner.Air blast joint 36 (not shown) are sealed in the rotation of mode conversion switch 22 simultaneously, enter into dust bag 37,38 (not shown) with the air and the chip that guide suction.
Fig. 9 to Figure 11 illustrates when air blast vacuum cleaner is switched to air blast mode of operation by dust suction mode of operation, the operation of air blast vacuum cleaner safe locking mechanism 40.Now, outlet air air deflector is in outlet opening open position.
As shown in Figure 9, mode conversion switch 22 is activated by user and rotates around the pivot X being formed on fuselage 20, thereby activates the air blast mode of operation of air blast vacuum cleaner.
Figure 10 illustrates when mode conversion switch 22 turns to air blast mode of operation position, the mode conversion switch 22 of air blast vacuum cleaner safe locking mechanism 40 be in the lock state and dust bag joint 44 in released state.More specifically, first the bar shaped portion 46 of mode conversion switch 22 promotes head elements 54b so that circular lockplate 42 is rotated around pivot Y, and removes thus the locking between the outstanding auxiliary section 60 of dust bag joint 44 and the outstanding auxiliary section 52b of circular lockplate 42.Meanwhile, another outstanding auxiliary section 52c of circular lockplate 42 and the outstanding auxiliary section 48 of mode conversion switch 22 near.Thus, mode conversion switch 22 locks with circular lockplate 42, and outlet air air deflector forwards outlet opening closed position to.Like this, user is actuation patterns change-over switch 22 directly, and the pipe outlet hole of fuselage 20 that therefore leads to impeller/blower fan is sealed by mode conversion switch 22.
Figure 11 illustrates the situation that dust bag joint 44 is removed in the time that air blast vacuum cleaner is switched to air blast mode of operation.As shown in figure 10, dust bag joint 44 is removed from air blast vacuum cleaner, and meanwhile, the pipe outlet hole of the fuselage 20 of impeller/blower fan is led in mode conversion switch 22 sealings, to guide air to blow out by air blast external member.
Figure 12 A and Figure 12 B illustrate another schematic diagram of the operating process of the air blast vacuum cleaner safe locking mechanism of Fig. 4, and the lock operation of locking mechanism is shown in these figure better.
In Figure 12 A, air blast vacuum cleaner just moves under dust suction mode of operation, and therefore dust bag joint 44 locks with circular lockplate 42 and mode conversion switch 22 does not engage with circular lockplate 42.In this case, the outstanding auxiliary section 60 of dust bag joint 44 is against the outstanding auxiliary section 52i of circular lockplate 42.The bar shaped portion 70 of dust bag joint 44 arranges near circular lockplate 42, and promotes head elements 54k and overcome the bias voltage of spring and press head elements 54j.Consequently user can not directly take out dust bag 37,38 (not shown), and therefore can not access impeller/blower fan.
In Figure 12 B, air blast vacuum cleaner is switched under air blast mode of operation and moves, and therefore mode conversion switch 22 locks with circular lockplate 42 and dust bag joint 44 does not engage with circular lockplate 42.In this case, the outstanding auxiliary section 48 of mode conversion switch 22 is against the outstanding auxiliary section 52l of circular lockplate 42.The bar shaped portion 46 of mode conversion switch 22 is near the another side setting of circular lockplate 42, and promotes head elements 54n and overcome the bias voltage of spring and press head elements 54m.Like this, directly actuation patterns change-over switch 22 of user.Meanwhile, mode conversion switch 22 is blocked the control of dust opening of fuselage 20, can not access impeller/blower fan so that obtain user.The outstanding auxiliary section 52 that it should be noted that circular lockplate 42 can or be extended in the same side vertically from the opposite side of circular lockplate 42.
In a word, no matter air blast vacuum cleaner is switched to air blast mode of operation or is switched to dust suction mode of operation by air blast mode of operation by dust suction mode of operation, circular lockplate 42 is all to rotate around the same direction of pivot Y-direction, thereby at different latched position the locking and unlocking mode conversion switch 22 and dust bag joint 44.Therefore, in the time of the dust suction mode of operation of air blast vacuum cleaner, dust bag 27,28 has sealed the pipe outlet hole being arranged between dust bag 37,38 and fuselage 20, can not directly access impeller/blower fan so that obtain user.In the time of the air blast mode of operation of air blast vacuum cleaner, outlet air air deflector is positioned at outlet opening closed position, has sealed the pipe outlet hole being arranged between dust bag 37,38 and fuselage 20, again can not directly access impeller/blower fan so that obtain user.
It should be noted that, in the situation that not departing from spirit of the present utility model, the safe locking mechanism in the utility model can be applied to the power tool of any type, especially the air blast vacuum cleaner of power type or air-driven type.
