The present application provides a cleaning apparatus and a handle assembly, each of which is described in detail below. It should be noted that the following description order of the embodiments is not intended to limit the preferred order of the embodiments of the present application. In the following embodiments, the descriptions of the embodiments are focused on, and for the part that is not described in detail in a certain embodiment, reference may be made to the related descriptions of other embodiments.

Referring to fig. 1, an embodiment of the present application provides a cleaning apparatus including a main body and a handle assembly including a receiving member 200, a telescopic member 300, and a grip member 400.

Wherein the main body substantially forms the structural basis and the contour of the cleaning device, and the other components of the cleaning device are usually arranged directly or indirectly on the main body. For example, when the cleaning apparatus is a floor mopping robot, the main body may include a body assembly of the floor mopping robot, and a mop, a roller, a suction source, etc. disposed on the body assembly. Still further exemplary, when the cleaning apparatus is a lawn mower, the main body may include a body assembly of the floor scrubber, and a cutting assembly, a roller, a suction source, etc., disposed on the body assembly. Of course, the present embodiment is not limited thereto.

The accommodating member 200 is disposed on the main body, and is used for accommodating at least part of the telescopic member 300, where the telescopic member 300 can be accommodated in the accommodating member 200 when not in use, so as to help reduce occupation of external space. Typically, the accommodating element 200 is disposed on one side of the main body, for example, the moving direction of the cleaning device is used as the forward direction, the accommodating element 200 is disposed on the rear side or the front side of the cleaning device, and correspondingly, other structures of the handle assembly are also disposed on the rear side or the front side of the cleaning device, so that the cleaning device can be pulled or pushed by a user conveniently. Illustratively, with continued reference to FIG. 1, the main body includes a top bracket 100, the top bracket 100 being positionable at a top position of the rear side of the cleaning apparatus, the handle assembly being disposed at the rear side of the top bracket 100. Of course, the present embodiment is not limited thereto.

Here, the receiving member 200 may be a separately prepared member, which is connected to the main body by means of a snap fit, welding, bolting, etc., or in other embodiments, the receiving member 200 may be integrally formed with the body assembly of the main body, i.e. the receiving member 200 may be regarded as a part of the main body, which is not limited in this embodiment.

The telescopic member 300 has a telescopic function, and is telescopically disposed in the housing member 200. Further, at least a portion of the telescoping member 300 may be retracted into the housing member 200 when not in use, and the telescoping member 300 may be extended for user operation of the handle assembly when in use. Here, the telescopic member 300 has a first end 330 (refer to fig. 2) and a second end 340 opposite to each other, in the direction of illustration shown in fig. 1, the first end 330 is an upper end of the telescopic member 300, the second end 340 is a lower end of the telescopic member 300, which will be exemplified below, but it will be understood that, in other embodiments, the placement positions of the telescopic member 300 and the accommodating member 200 may be adjusted according to actual needs, i.e. the first end 330 is not limited to be an upper end, and the second end 340 is not limited to be a lower end, which is not unduly limited by the illustration of the present embodiment.

The grip 400 may be a handle body for a user to handle the cleaning device after gripping. Here, the grip 400 is disposed at the first end 330 of the telescopic member 300, that is, the grip 400 is disposed at the upper end of the telescopic member 300 in the direction shown in fig. 1, it will be understood that the grip 400 is not limited to being disposed at the end of the first end 330 in other embodiments, and the grip 400 need only be disposed closer to the first end 330 than the second end 340. Of course, when the grip 400 is disposed at the end of the first end 330, the portion exposed outside the receiving member 200 is less when the telescopic member 300 is contracted, which can better reduce the occupation of the external space.

Herein, referring to fig. 1, in some embodiments, the accommodating member 200 is a pull rod tube, and two pull rod tubes are disposed in parallel, and both pull rod tubes extend lengthwise along the first direction X. The telescopic members 300 are correspondingly pull rods, and are arranged corresponding to the pull rod pipes, namely, one pull rod is arranged in each pull rod pipe, the two pull rods also extend lengthwise along the first direction X, the holding member 400 is connected between the first ends 330 of the two pull rods, and the holding member 400 is specifically an elongated handle body so as to be convenient for a user to operate. Here, the two tie rod pipes and the tie rod have the same structure, and one of the tie rod pipes and the tie rod provided corresponding thereto will be described as an example. It should be understood that, in other embodiments, other numbers of draw bar pipes may be provided, that is, the number of the accommodating members 200 and the telescopic members 300 is not limited in this embodiment, and the number of the accommodating members 200 and the telescopic members 300 may be 1, 3, 4, or other numbers.

The pull rod pipe includes a body 210 and a rotating bracket part 220, the body 210 and the rotating bracket part 220 are communicated with each other and formed with a first receiving space 211 extending along a first direction X, and an opening 221 (see fig. 4) is provided at an end of the rotating bracket part 220 near the grip 400, i.e., an upper end of the pull rod pipe, the opening 221 being communicated to the first receiving space 211 to allow the pull rod to pass through when being extended and contracted. Here, the body 210 and the rotating bracket 220 may be formed by a bolt connection, a clamping connection, a magnetic connection, or the like, or may be formed integrally, which is not limited in this embodiment.

Here, it should be noted that, in the example shown in fig. 1, the body 210 includes side walls disposed on three sides, that is, the body 210 of the left and right two tie rod tubes is not disposed on the side close to each other, but in other embodiments, the body 210 may be a structure in which the tie rods are surrounded by four sides, for example, a through hole is disposed in the interior of the body 210 for forming a part of the first accommodating space 211, and the tie rods or other expansion members 300 may be accommodated in the through hole.

Here, the pull rod is movable along the first direction X, which includes, in particular, forward movement along the first direction X and reverse movement along the first direction X. When the pull rod moves in the reverse direction of the first direction X, the pull rod moves toward the pull rod pipe, the pull rod is received in the first receiving space 211 of the pull rod pipe, and the grip 400 at the position of the first end 330 of the pull rod is still located outside the pull rod pipe, and at this time, the pull rod is located in the first state. In this embodiment, the tie rod is entirely located in the tie rod pipe in the first state, however, it is understood that in other embodiments, at least a portion of the telescopic member 300 may be accommodated in the accommodating member 200 in the first state, and some portion of the telescopic member 300 may not be located in the accommodating member 200 at a position close to the holding member 400, that is, some portion may still be located outside the accommodating member 200 along the first direction X, which is not limited in this embodiment.

Referring to fig. 2, when the pull rod moves in the forward direction of the first direction X, the pull rod protrudes from the opening 221 of the pull rod pipe, and accordingly the grip 400 at the first end 330 of the pull rod is pulled out for the user to use, and the pull rod is in the second state. In the second state, the telescoping member 300 extends outwardly from the housing member 200 as compared to the first state. Here, in both the first state and the second state, the extension direction of the tie rod is parallel to or coincides with the first direction X, and the second ends 340 of the tie rod are located in the first accommodation space 211.

Here, in some embodiments, referring to fig. 5, a limiting portion 222 may be further disposed at the opening 221, where the limiting portion 222 is configured to limit a portion of the telescopic member 300 to the accommodating member 200, so as to prevent the telescopic member 300 from being separated from the accommodating member 200.

Illustratively, on the rotating bracket 220, a portion protruding toward the radial inner side of the opening 221 is provided to form the limit portion 222, and correspondingly, on the telescopic member 300, a protruding portion 310 is provided toward the radial outer side at a position corresponding to the limit portion 222, and the limit portion 222 can cooperate with the protruding portion 310 to form a limit position. Here, when the expansion member 300 extends outward through the opening 221 and reaches the position where the limiting portion 222 abuts against the side of the protruding portion 310 near the opening 221 along the first direction X, that is, reaches the limiting position, the expansion member 300 cannot move outward along the first direction X due to the limitation of the limiting portion 222, so that the expansion member 300 is prevented from being separated from the accommodating member 200. Here, the rotation bracket portions 220 of the two draw bar pipes are provided with the limiting portions 222 and the protruding portions 310, and the two sets of limiting portions 222 and protruding portions 310 are disposed on the sides of the two draw bar pipes, but it will be understood that in other embodiments, the limiting portions 222 and protruding portions 310 may be disposed on other sides of the accommodating member 200, which is not limited in this embodiment.

It will be appreciated that in the above embodiments, the telescoping of the telescoping member 300 is achieved by movement of the telescoping member 300 in the first direction X, while in other embodiments, the telescoping of the telescoping member 300 may be achieved in other ways. For example, the telescopic member 300 may include a plurality of sleeves sequentially connected along the first direction X, the diameter of the latter sleeve is smaller than that of the former sleeve so as to be accommodated in the former sleeve, the telescopic member 300 may be extended when the sleeves advance along the first direction X, and when the telescopic member is extended, a limit is formed between ends of two adjacent sleeves by a holding portion extending toward the inner side in the radial direction so as to prevent the sleeves from being separated from each other, and the plurality of sleeves retract along the first direction X so as to accommodate the latter sleeve in the former sleeve, thereby achieving shrinkage. Alternatively, the surface of the expansion member 300 may be provided with corrugation to form expansion joints, and expansion and contraction of the expansion member 300 may be achieved.

Here, the telescopic member 300 may be positioned at a position where it is inconvenient for a user to grip and operate after being extended. Thus, in some embodiments, the handle assembly is configured to allow for adjustment of the setting angle of the telescoping member 300.

Referring to fig. 3, in some embodiments, after the telescopic member 300 is in the second state, the telescopic member 300 may be rotated and reach a third state, and in the third state after rotation, the setting angle of the telescopic member 300 is different compared to the setting angle in the second state. Illustratively, the expansion member 300 is changed from extending along the first direction X to extending along the second direction Y, and the first direction X and the second direction Y are disposed at an angle, i.e. the first direction X and the second direction Y are not parallel and do not coincide.

Here, referring to fig. 4 again, at the rotating bracket portion 220, a second receiving space 223 is further provided, the second receiving space 223 extends along the second direction Y, and the second receiving space 223 communicates with the first receiving space 211. Here, when the telescopic member 300 is in the second state, the second end 340 of the telescopic member is located in the rotating bracket portion 220 and located at one side of the second accommodation space 223. The expansion member 300 may be rotated to selectively fit the second end 340 of the expansion member 300 into the first accommodation space 211 and the second accommodation space 223. Illustratively, in the condition shown in fig. 4, the telescoping member 300 is in the second condition, and the second end 340 (i.e., the lower end in the illustrated condition) of the telescoping member 300 is positioned within the first receiving space 211. At this time, referring to fig. 6, the second end 340 of the telescopic member 300 may be rotated into the second accommodating space 223 by rotating, and at this time, the telescopic member 300 is rotated in a state parallel to the second direction Y, that is, in the third state, the extending direction of the telescopic member 300 is the second direction Y. Of course, the second end 340 of the telescopic member 300 may be rotated into the first accommodating space 211 again by rotating, so that the telescopic member 300 is in the second state.

As mentioned above, in some embodiments, the extension member 300 is provided with a protrusion 310, where a cylindrical protrusion 310 may be disposed on the extension member 300 near the second end 340 thereof, where the protrusion 310 may be used as a rotation axis, the extension member 300 may rotate along the axis of the rotation axis, and the cylindrical protrusion 310 may make the rotation of the extension member 300 more stable, and of course, in other embodiments, the protrusion 310 may be disposed in other shapes, which is not limited in this embodiment. Referring to fig. 5, in the second state, the protruding portion 310 is limited by the limiting portion 222, and at the same time, the telescopic member 300 rotates with the axis of the protruding portion 310 as the rotation axis, so as to reach the third state. The protruding portion 310 is limited by the limiting portion 222, and provides a supporting point for the rotation of the telescopic member 300, so that the telescopic member 300 can rotate more stably, displacement or shaking is not easy to occur during rotation, that is, the protruding portion 310 simultaneously plays a role in limiting the telescopic member 300 and improving the rotation stability of the telescopic member 300.

Furthermore, in some embodiments, referring to fig. 4, a locking portion 320 may be further disposed on the telescopic member 300, and correspondingly, an engaging portion 224 may be disposed in the second accommodating space 223 at a position corresponding to the locking portion 320. Illustratively, the locking portion 320 is a protruding portion, the engaging portion 224 is a recessed portion, and an elastic member 600 (see fig. 7) is disposed between the protruding portion and the telescopic member 300, and the elastic member 600 applies a force directed to the recessed portion to the protruding portion so that the protruding portion can be engaged into the recessed portion. The elastic member 600 may be a spring, a clip spring, or the like. Thus, in the third state, when the extension member 300 is coupled to the second receiving space 223, the locking portion 320 may be coupled with the coupling portion 224 to lock the second end 340 of the extension member 300 in the second receiving space 223, i.e., lock the extension member 300 in the third state.

Here, referring to fig. 7, an unlocking portion 500 is further disposed on the telescopic member 300, and the unlocking portion 500 is drivingly connected to the protruding portion, so as to overcome the force of the elastic member 600 and release the engagement between the protruding portion and the recessed portion.

Illustratively, the unlocking part 500 includes an unlocking switch 510, a first unlocking link 520, a second unlocking link 530, and an unlocking transmission 540. The first unlocking connector 520 and the second unlocking connector 530 are used to connect the components, and it is understood that in other embodiments, the first unlocking connector 520 and the second unlocking connector 530 may not be provided, and the unlocking switch 510 may be directly connected to the unlocking transmission member 540, and the unlocking transmission member 540 may be directly connected to the protruding portion.

Here, the inside of the grip 400 has an inner cavity, the first unlocking connector 520 is disposed in the inner cavity, the unlocking switch 510 is connected to the first unlocking connector 520, and a portion of the unlocking switch 510 is exposed at a side of the grip 400 near the telescopic member 300 for a user to operate. In addition, when in use, the unlocking switch 510 is not easy to contact and collide with the outside, so that misoperation can be avoided. Of course, in other embodiments, the unlocking portion 500 may be disposed at another position of the grip 400 or disposed on another component, which is not limited in this embodiment.

The first unlocking connection member 520 extends to the connection of the grip 400 and the telescopic member 300, and is connected to one end of the unlocking transmission member 530. Here, in the illustrated direction shown in fig. 7, there are left and right telescopic members 300, and each telescopic member 300 is provided with a locking part 320, and thus, there are correspondingly provided two unlocking transmission members 530 corresponding to the number of the telescopic members 300, where the first unlocking connection member 520 is connected to two unlocking transmission members 530 to enable the two unlocking transmission members to move, and the unlocking transmission members may be transmission rods or transmission ropes, etc., which are not limited in this embodiment. Of course, in other embodiments, the number of the telescopic members 300 and the locking portions 320 may be different, and the number of the unlocking transmission members 530 may be adjusted accordingly. For example, only one expansion element 300 may be provided, in which case only one unlocking transmission element 530 may be provided; also, for example, when two or more telescoping members 300 are provided, only a part of the telescoping members 300 may be provided with the locking portions 320, for example, only one of the telescoping members 300 is provided with the locking portions 320, and correspondingly, the number of unlocking transmission members 530 is also set to one.

Here, the unlocking transmission 530 is disposed in the telescopic member 300 and extends in the longitudinal direction of the telescopic member 300, and in the illustrated state shown in fig. 7, the unlocking transmission 530 extends in the second direction Y. The other end of the unlocking transmission member 530 is connected to the second unlocking connection member 540, the second unlocking connection member 540 is connected with the locking portion 320 at a side far away from the unlocking transmission member 530, and the elastic member 600 is further disposed between the locking portion 320 and the second unlocking connection member.

Here, the unlocking part 500 forms a push type switch structure. In fig. 7, when the unlocking switch 510 is pressed along the second direction Y, the unlocking switch 510 moves in the second direction Y, and drives the first unlocking link 520, the unlocking transmission member 530, the second unlocking link 540, and the locking portion 320, which are connected to each other, to move in the second direction Y, and at this time, the locking portion 320 may release the engagement with the engagement portion 224. When the pressing force is released, the locking portion 320 moves in the opposite direction of the second direction Y under the force of the elastic member 600 and can be engaged with the engaging portion 224 to form a locking.

It should be understood that, in other embodiments, the locking portion 320 may be a concave portion, and correspondingly, the engaging portion 224 is a protruding portion, and the elastic member may be disposed between the engaging portion 224 and the rotating bracket portion 220, so that the elastic member supports the engaging portion 224 and makes the locking portion 320 engage with the engaging portion 224; alternatively, in other embodiments, the locking portion 320 and the mating portion 224 may have other structures, for example, both may be magnetic pieces, so that magnetic engagement may be implemented, or both may be implemented in a snap fit manner, which is not limited in this embodiment. In other embodiments, the structure of the unlocking portion 500 is not limited to the above, and the engagement between the locking portion 320 and the engaging portion 224 may be released by operating the unlocking portion 500.
