Detailed Description

Fig. 1 is a front view of a cleaning apparatus 100 according to one embodiment of the present invention. As shown in FIG. 1, the present invention provides a handheld cleaning appliance 100 that may generally include a dirt cup assembly 10, a motor assembly 20, a battery pack assembly 30 for powering the motor assembly 20, and a handle 40 for grasping. I.e. the hand-held cleaning device 100 is a hand-held cleaner from the belt pack assembly 30. The dust cup assembly 10, the motor assembly 20, and the battery pack assembly 30 are sequentially horizontally arranged and coupled to form the body 50 of the cleaning apparatus 100, the handle 40 is disposed above the body 50, and the dust cup assembly 10 and the battery pack assembly 30 are separately disposed near both ends of the handle 40.

The cleaning apparatus 100 of the present embodiment horizontally and integrally couples the dirt cup assembly 10, the motor assembly 20, and the battery pack assembly 30 to each other, i.e., the body 50, in order to make the center of gravity distribution relatively uniform. And the handle 40 is arranged above the body 50, and the heavier motor, the battery pack assembly 30 and the like are arranged at the bottom of the handle 40, and the bottom of the body 50 is placed on the supporting surface when the cleaning device 100 is normally placed, so that an operator can take the cleaning device 100 in a labor-saving manner through the lifting action when using the cleaning device 100. That is, in this embodiment, the components are reasonably arranged, the dust cup assembly 10, the motor assembly 20 and the battery pack assembly 30 are horizontally arranged in sequence, so that the center of gravity of the body 50 is uniformly distributed, and the handle 40 is arranged above the body 50 with a large weight, so that the problem of labor-consuming operation is solved.

As shown in fig. 1, in one embodiment, at least 2 of the bottom of the dirt cup assembly 10, the bottom of the motor assembly 20, and the bottom of the battery pack assembly 30 together form a plane for supporting the cleaning apparatus. That is, the present embodiment uses the bottoms of at least two of the three components of the dirt cup assembly 10, the motor assembly 20, and the battery pack assembly 30 as a plane for supporting the entire cleaning apparatus 100. For example, the bottom of the dirt cup assembly 10 and the bottom of the battery pack assembly 30 are considered to be the placement planes. In this embodiment, at least two of the bottom of the dust cup assembly 10, the bottom of the motor assembly 20 and the bottom of the battery pack assembly 30 are directly used as the placement planes, so that the overall dimensions of the three are well utilized, and the bottom plane for placing the cleaning device 100 is not required to be specially arranged, so that the structure is simplified, and the materials are saved.

In other embodiments, a connection part may be disposed between the dust cup assembly 10, the motor assembly 20 and the battery pack assembly 30, and the bottom of the connection part may protrude below the bottom surface of the dust cup assembly 10, the motor assembly 20 or the battery pack assembly 30, that is, the connection part may also be used as a placement plane, and the connection part may be disposed in a relatively stable plane or the like as required. Of course, the cleaning device 100 may also be provided with a special placement plane.

Fig. 2 is a top view of a cleaning apparatus 100 according to one embodiment of the invention. In another embodiment, as shown in fig. 2, the dirt cup assembly 10, the motor assembly 20, and the battery pack assembly 30 are all generally cylindrical in shape, with their central axes parallel or coplanar with one another (see fig. 1 for a coplanar condition). Preferably, the central axes of the dirt cup assembly 10, the motor assembly 20, and the battery pack assembly 30 are parallel and coplanar.

The placement plane formed by the at least two cylindrical surfaces can firmly support the cleaning apparatus 100, and the arrangement of the center axes of the three parallel or coplanar with each other can also better control the distribution of the center of gravity of the body 50, facilitating the balanced arrangement of the center of gravity.

In one embodiment, as shown in fig. 1, the three components of the dust cup assembly 10, the motor assembly 20 and the battery pack assembly 30 satisfy 0.5×m1×l1+.m2×l2+.m1×l1, where M1 is the weight of the battery pack assembly 30, L1 is the linear distance between the center line of the battery pack assembly 30 and the center line of the motor assembly 20, M2 is the weight of the dust cup assembly 10, and L2 is the linear distance between the center line of the dust cup assembly 10 and the center line of the motor assembly 20.

In this embodiment, the moment of the dust cup assembly 10 relative to the center line of the motor assembly 20 and the moment of the battery pack assembly 30 relative to the center line of the motor assembly 20 are set in the above relationship, so that the centers of gravity of the three components can be well balanced. For example, setting M2 x L2 equal to 0.5 x M1 x L1, the body 50 tends to tilt rearward relative to the centerline of the motor assembly 20; setting M2 x L2 equal to 2 x M1 x L1, the body 50 tends to tilt backward with respect to the center line of the motor assembly 20, and according to this rule, a user can relatively adjust the hand-holding position, so as to clean dust in a larger range.

Optionally, M2 x L2 is set to be slightly greater than M1 x L1, so that the body 50 is in a slightly forward inclined state, which is beneficial for an operator to control the operation angle, and the operation is easy and labor-saving.

In one embodiment, the three of the dirt cup assembly 10, the motor assembly 20, and the battery pack assembly 30 satisfy m1=m2×l2. I.e., the body 50 is balanced back and forth with respect to the center line of the motor assembly 20, there is no significant tendency to topple over, so that an operator can well grasp the center of gravity of the cleaning apparatus 100 and perform a cleaning operation stably.

In another embodiment, as shown in fig. 1, the handle 40 has a first portion 41 and a second portion 42 that are angled with respect to each other, and the intersection of the first portion 41 and the second portion 42 is located directly above the motor assembly 20.

In this embodiment, the inflection point of the handle 40 is disposed just above the motor assembly 20, and the center of gravity of the body 50 is substantially concentrated at the motor assembly 20, so that when the cleaning apparatus 100 is lifted through the inflection point, since the lifting point is located substantially on the vertical line of the center of gravity of the body 50, the weight distribution is balanced and the lifting is stable.

Alternatively, as shown in fig. 1, the angle a between first portion 41 and second portion 42 is between 90 ° and 150 °. The handle 40 is arranged in an obtuse-angle bent shape, so that the hand of an operator can be conveniently put in, the ergonomics are met, and the operation is smoother and more comfortable. The handle 40 may be formed in two straight portions which are bent, or may be formed in a circular arc shape or other comfortable curved shape. The inner side of the handle 40, i.e. the hand grip, may be provided with a pattern for anti-slip.

In one embodiment, as shown in fig. 1, second portion 42 is at an angle B of between 45 ° and 80 ° to the support surface when body 50 is supported on the surface. The inclined condition of the second portion 42 of the handle 40 facilitates the insertion and gripping of the operator's hand when the angle B is set between 45 ° and 80 °. Alternatively, angle B is set to 56 ° which is a relatively comfortable operating angle for many trials, complying with ergonomic requirements. Meanwhile, the height of the handle 40 may be set to be adjustable so as to be adjustable according to the height of the operator, so that the operator can take up the cleaning apparatus 100 more effort without bending down a large angle.

In another embodiment, as shown in FIG. 1, the handheld cleaning appliance 100 further includes a suction opening assembly 60 in communication with the air intake of the dirt cup assembly 10, the suction opening assembly 60 being located at the periphery of the dirt cup assembly 10 and being disposed substantially tangentially. The arrangement makes the joint of the suction port assembly 60 and the dust cup assembly 10 be the inclined surface of the suction port assembly 60, so that the passage area of the suction port assembly 60 and the dust cup assembly can be effectively increased, the suction of dust is facilitated, the blockage is not easy, and the efficient dust collection is realized.

As shown in fig. 1, alternatively, the axis of the suction opening assembly 60 and the axis of the first portion 41 of the handle 40 are parallel or coincident with each other, and the axis of the suction opening assembly 60 forms a planar angle C with the central axes of the dirt cup assembly 10, the motor assembly 20, and the battery pack assembly 30 of between 20 ° and 60 °. The included angle C of the present embodiment is set between 20 deg. and 60 deg. to ensure a natural inclined sagging state of the suction opening assembly 60, which enables effective cleaning of the floor and a cleaning surface with a certain height when the hand-held cleaning apparatus 100 is operated.

As shown in FIG. 2, in one embodiment, the axis of the suction opening assembly 60 and the axis of the handle 40, and particularly the axis of the first portion 41 of the handle 40, are perpendicular to the central axis of the motor assembly 20 in a top view, such that the suction opening assembly 60 and the handle 40 are disposed relatively uniformly without tilting in a side-to-side direction relative to the body 50.

Further, as shown in fig. 2, the dirt cup assembly 10, the motor assembly 20, and the battery pack assembly 30 are all substantially laterally symmetrical along the axis of the handle 40 in a top view such that the entire cleaning apparatus 100 is laterally symmetrical and does not tilt laterally.

In another embodiment, not shown, the main body 50 of the cleaning apparatus 100 formed by sequentially arranging and coupling the dust cup assembly 10, the motor assembly 20, and the battery pack assembly 30 is replaced by the main body 50 of the cleaning apparatus 100 formed by sequentially arranging and coupling the dust cup assembly 10, the battery pack assembly 30, and the motor assembly 20, and the corresponding structures and positional relationships are synchronously changed.

That is, the positions of the battery pack assembly 30 and the motor assembly 20 in the above-described embodiment are interchanged, and the battery pack assembly 30 is set at the position of the approximate center of gravity, and the above-described technical effects can be obtained by such interchange.

Fig. 3 is a front view of the cleaning apparatus 100 according to another embodiment of the present invention in a conventional state. As shown in FIG. 3, in one embodiment, the handheld cleaning device 100 further includes a wand assembly 70 and a floor brush 80. The form of the floor brush 80 may be any of the prior art. Alternatively, the floor brush 80 may have the functions of beating, vibrating, sterilizing by illumination, and the like. The nipple assembly 70 communicates with the suction opening assembly 60 and is detachably connected to the suction opening assembly 60 such that the two have at least a first docked condition and a second docked condition with axes coincident or parallel. In the first docking state, the handle 40 is above the ground than the body 50; in the second docked state, the handle 40 is positioned below the floor surface, such as the floor surface, sofa surface, wall surface, etc. of the house, as compared to the body 50. A floor brush 80 is connected to an end of the wand assembly 70 remote from the suction opening assembly 60, and the floor brush 80 has a suction opening for sucking in dust. I.e. the floor brush 80 is in direct contact with the surface to be cleaned, dust enters the dirt cup assembly 10 via the floor brush 80, the wand assembly 70 and the suction opening assembly 60. The working range of the cleaning apparatus 100 can be increased, and the cleaning more distant or higher place can be cleaned, by the arrangement of the floor brush 80 and the wand assembly 70.

Fig. 4 is a front view of a cleaning apparatus 100 according to another embodiment of the present invention in an inverted state. As shown in fig. 3, the cleaning apparatus 100 is in a conventional cleaning state, i.e., the first docking state described above, after the wand assembly 70 and the floor brush 80 are attached. As shown in fig. 4, the cleaner is turned upside down, and the first portion 41 of the handle 40 is attached to a surface to perform a cleaning operation, so that a very low cleaning angle, i.e., the above-mentioned second docking state, can be obtained. For example, the first portion 41 of the handle 40 may be attached to the floor, and a low environment such as a bed bottom, a sofa bed, etc. may be used.

By now it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been shown and described herein in detail, many other variations or modifications of the invention consistent with the principles of the invention may be directly ascertained or inferred from the present disclosure without departing from the spirit and scope of the invention.
