In addition, in some embodiments of the invention, hood 2 can be used as motor cover to generate the suction of negative pressure for the cover Force motor (i.e. suction motor is located in hood 2), and in some other embodiment of the invention, hood 2 is also used as having There is the cover (such as device, such as the cover cyclone separator other than the cover suction motor etc.) of other function, at this time suction Motor can be located at other positions (i.e. suction motor is not arranged in hood 2).

Referring to Fig.1 with Fig. 6 and in conjunction with Fig. 2 and Fig. 9, fuselage 3 is movably connected with hood 2 and can synchronous front and back turn with hood 2 Dynamic (i.e. swing) and opposite hood 2 can left-right rotations.That is, on the one hand (referring to Fig.1 and Fig. 6), hood 2 is opposite Installation part 11 pivot forward during, fuselage 3 synchronize and dump forward with respect to scrubbing brush 1 with hood 2,2 opposite mount 11 of hood During pivoting backward, fuselage 3 topple over backward with hood 2 with respect to the synchronization of scrubbing brush 1, on the other hand (referring to Fig. 2 and Fig. 9), machine Body 3 can control torsion with respect to hood 2, i.e., while hood 2 is in the lateral direction and without twisting action, fuselage 3 can be with Left and right twisting action is carried out independently of hood 2.Here, it should be noted that "available" as described herein is referred to unobstructed In the state of under the premise of effect or by facilitation.

Referring to Fig. 4 and Fig. 8, locking assembly 4 is movably connected with hood 2, that is to say, that locking assembly 4 is mounted on hood 2 And opposite hood 2 moves.There is rotation lock piece A1 on installation part 11, there is twist lock stop member B1, locking assembly on fuselage 3 There is rotation lock-bit portion A2 and torsion lock-bit portion B2, rotation lock-bit portion A2 and rotation lock piece A1 composition can limit cooperation on 4 Anti- rotation component, torsion lock-bit portion B2 and twist lock stop member B1 composition can limit the anti-torsion component of cooperation.

Referring to Fig. 4, when anti-torsion component, which limits, to be cooperated, fuselage 3 be locked to respect to hood 2 can not left-right rotation, That is fuselage 3 cannot carry out left and right torsion with respect to hood 2 again when reversing lock-bit portion B2 and twist lock stop member B1 limit cooperation Turn (i.e. fuselage 3 cannot carry out left and right twisting action independently of hood 2), and when torsion lock-bit portion B2 and twist lock stop member B1 is de- (referring to Fig. 8) when from cooperation, the opposite hood 2 of fuselage 3 can carry out left and right torsion, and (i.e. fuselage 3 can carry out a left side independently of hood 2 Right twisting action).

Specifically, anti-torsion component cooperates with the limit of anti-rotation component and limits cooperation, matches with the disengaging of anti-rotation component It closes and is detached from cooperation.That is, when rotation lock-bit portion A2 and rotation lock piece A1 limit cooperates, reversing lock-bit referring to Fig. 4 Portion B2 and twist lock stop member B1 also limit cooperation；Referring to Fig. 8, when rotation lock-bit portion A2 and rotation lock piece A1, which is detached from, to be cooperated, Torsion lock-bit portion B2 and twist lock stop member B1 are also detached from cooperation.

Referring to Fig. 4 and Fig. 8, during hood 2 before and after scrubbing brush 1 with respect to pivoting, the lock that front and back rotates is synchronized with hood 2 Rotation lock-bit portion A2 on the hyte part 4 and rotation lock piece A1 on scrubbing brush 1 may be implemented limit cooperation and be detached from cooperation.Its In, (such as Fig. 4 when hood 2 drives locking assembly 4 to move to the position of rotation lock-bit portion A2 and rotation lock piece A1 limit cooperation It is shown), torsion lock-bit portion B2 and twist lock stop member B1 also limit cooperation, turn round at this point, fuselage 3 not can be carried out left and right with respect to hood 2 Rotation is made, so as to ensure that fuselage 3 is in the stability of standing (as shown in Figure 1) of upright state；And when hood 2 drives lock-bit Component 4 moves to (as shown in Figure 8) when rotation lock-bit portion A2 and rotation lock piece A1 is detached from the position of cooperation, reverses lock-bit portion B2 It is also detached from cooperation with twist lock stop member B1, at this point, fuselage 3 can carry out left and right twisting action (as shown in Figure 9) with respect to hood 2, So as to ensure that fuselage 3 is in the using flexible of retroverted state.

In short, by the way that mobilizable locking assembly 4 is arranged on the hood 2 being connected between scrubbing brush 1 and fuselage 3, from And can by the interoperation of the anti-rotation component between scrubbing brush 1 and locking assembly 4, be dexterously converted into locking assembly 4 and machine The interoperation of anti-torsion component between body 3, and then reliably and effectively realize the opposite rotation stop between scrubbing brush 1 and fuselage 3 Control, in this way, no matter between scrubbing brush 1 and fuselage 3 whether distance apart from each other, the control of effective and reliable rotation stop may be implemented (the remote rotation stop control between scrubbing brush 1 and fuselage 3 especially may be implemented), meets the work and requirement of dust catcher 100, It reduces and the structure of dust catcher 100 is limited, improve applicability.

To sum up, dust catcher 100 according to an embodiment of the present invention, by the way that mobilizable locking assembly 4 is arranged on hood 2, So as to realize that effective rotation stop between fuselage 3 and scrubbing brush 1 controls, the space being laid out to 100 complete machine structure of dust catcher is reduced It is required that so that some scrubbing brushes 1 and the dust catcher 100 of the layout apart from each other of fuselage 3 also can be realized effective and reliable rotation stop control System, such as some dust catchers 100 that suction motor is placed on to (such as between scrubbing brush 1 and fuselage 3) below rotary joint Meaning it is significant.In addition, dust catcher 100 according to an embodiment of the present invention, by the way that locking assembly 4 can be connected to hood 2, it can also be effectively saved space, so that the overall structure of dust catcher 100 is more compact, appearance is more beautiful.

In some currently preferred embodiments of the present invention, referring to Fig. 3 and Fig. 4, (work as pendulum when anti-rotation component, which limits, to be cooperated When twist lock position portion A2 and rotation lock piece A1 limit cooperates), hood 2 is locked to can not front and back rotation (i.e. fuselage relative to scrubbing brush 1 3 opposite scrubbing brushes 1 are in the state that cannot be leaned forward and fall afterwards), referring to Fig. 7 and Fig. 8, and when anti-rotation component is detached from and cooperates ( When rotation lock-bit portion A2 and rotation lock piece A1, which are detached from, to be cooperated), hood 2 with respect to scrubbing brush 1 can front and back rotation (i.e. fuselage 3 is relatively Scrubbing brush 1 is in the state that can be leaned forward and fall afterwards).

In this way, being acted on by the linkage of locking assembly 4, anti-torsion component, which also limits, matches when anti-rotation component limits and cooperates Close, thus fuselage 3 with respect to scrubbing brush 1 can neither swing, torsion can not be controlled, suitable for be in the upright state that does not use with Ensure the upright stability of fuselage 3；And when anti-rotation component is detached from and cooperates, it is acted on by the linkage of locking assembly 4, anti-torsion group Part is also detached from cooperation, thus fuselage 3 with respect to scrubbing brush 1 both can with swing, torsion can also be controlled, suitable for be in use after Incline appoint turn state with ensure using flexibility.

Dust catcher 100 according to an embodiment of the present invention as a result, dexterously by the control of swing this aspect locking and a left side Right torsion this aspect locking control is set as being mutually related, so that while swing is locked up, controlling torsion It is locked simultaneously, while swing is released, controls torsion also while being released, and then greatly improve dust catcher 100 stability in non-working condition and the flexibility in use state, reduce the processing request of locking structure, improve Synchronism, reliability and the validity of above-mentioned two aspects locking control.

Here, it should be noted that the anti-front and back of vertical type dust collector in the related technology rotates and two sides of anti-left and right torsion The rotation stop in face controls mutually indepedent (i.e. dereferenced), causes control action complicated, control reliability is poor.For example, working as anti-rotation stop When the machining accuracy of structure is not high, it is more likely that on the other hand limited to realize again only after on the one hand realizing rotation stop wherein Turn.Such as when machining accuracy is not high, it may interfere anti-left and right torsion rotation stop can not while rotation rotation stop is realized when anti-front and back It realizes.And dust catcher 100 according to an embodiment of the present invention, pass through the setting activity on hood 2 and have rotation lock-bit portion A2 and The locking assembly 4 for reversing lock-bit portion B2, can efficiently solve the technical problem in the related technology.

Certainly, the invention is not limited thereto, in other embodiments of the invention, when anti-rotation component, which limits, to be cooperated, machine Cover 2 can also can not be locked to opposite scrubbing brush 1 can not front and back rotation state, that is to say, that anti-rotation component can not have to In the locking control for realizing swing, and the limit for being only used for controlling anti-torsion component cooperates and is detached from cooperation.At this point it is possible to Rotation lock-bit portion A2 and rotation lock piece A1 are processed more flexiblely.Such as in embodiments described below, when locking assembly 4 In lock-bit bracket 41 when can move up and down setting, anti-rotation component can be used for controlling the locking of swing；And work as lock-bit When lock-bit bracket 41 in component 4 can be moved forward and backward setting, anti-rotation component is not used in the locking of control swing.

In some embodiments of the invention, as shown in figure 5, locking assembly 4 includes: lock-bit bracket 41 and elastic component 42, rotation lock-bit portion A2 and torsion lock-bit portion B2 is both formed on lock-bit bracket 41 and lock-bit bracket 41 and 2 pivot bush unit of hood It is moved between the first position and the second position with opposite hood 2.Wherein, " pivot bush unit " refers to the movably company of being arranged It connects, such as in some specific examples of the invention, there is sleeve column portion 21 (or sleeve part 411) on hood 2, on lock-bit bracket 41 With sleeve part 411 (or sleeve column portion 21), by the way that sleeve part 411 to be set in sleeve column portion 21, lock-bit bracket 41 is with respect to hood 2 It can be rotated along the axially movable of sleeve column portion 21 and around the axis in sleeve column portion 21.
