The handle 40 is disposed above the body 50, the heavy motor, the battery pack assembly 30, and the like are disposed at the bottom of the handle 40, and the bottom of the body 50 is disposed on the support surface when the cleaning apparatus 100 is normally disposed, so that an operator can easily pick up the cleaning apparatus 100 by a lifting motion when using the cleaning apparatus 100. That is, in the present embodiment, the dust cup assembly 10, the motor assembly 20, and the battery pack assembly 30 are sequentially and transversely arranged to make the center of gravity of the body 50 be uniformly distributed, and the handle 40 is disposed above the body 50 with a large weight to solve the problem of labor waste in operation.

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 planar surface for supporting the cleaning device, as shown in figure 1. That is, the present embodiment uses the bottom 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 flat surface 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 taken as the rest planes. In the 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 placing planes, so that the overall dimensions of the three are well utilized, the bottom plane for placing the cleaning equipment 100 is not required to be specially arranged, the structure is simplified, and the material is saved.

In other embodiments, a connection portion 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 portion 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 portion may also be a placing plane, and the connection portion may be disposed in a relatively stable plane or the like according to requirements. Of course, the cleaning device 100 may be provided with a special resting plane.

Fig. 2 is a top view of a cleaning device 100 according to an embodiment of the present 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 with their central axes parallel or coplanar with one another (see fig. 1 for a coplanar state). 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 at least two cylindrical surfaces form a plane of placement that securely supports the cleaning device 100, and the parallel or coplanar arrangement of the central axes of the three may also better control the distribution of the center of gravity of the body 50, facilitating a balanced arrangement of the center of gravity.

In one embodiment, as shown in fig. 1, the three of the dirt cup assembly 10, the motor assembly 20, and the battery pack assembly 30 satisfy 0.5 × M1 × L1 ≦ M2 × L2 ≦ 2 × M1 × L1, where M1 is the weight of the battery pack assembly 30, L1 is the linear distance between the centerline of the battery pack assembly 30 and the centerline of the motor assembly 20, M2 is the weight of the dirt cup assembly 10, and L2 is the linear distance between the centerline of the dirt cup assembly 10 and the centerline of the motor assembly 20.

In this embodiment, the moment of the dirt cup assembly 10 relative to the centerline of the motor assembly 20 and the moment of the battery pack assembly 30 relative to the centerline of the motor assembly 20 are set in the above relationship, so that the center of gravity of the three components can be well balanced. For example, setting M2 × L2 equal to 0.5 × M1 × L1, the body 50 tends to tilt backwards with respect to the centerline of the motor assembly 20; and setting M2L 2 equal to 2M 1L 1, the body 50 has a tendency of tilting backwards relative to the central line of the motor assembly 20, and according to the rule, the operator can relatively adjust the hand holding position, thereby facilitating the cleaning of a larger range of dust.

Optionally, M2 × L2 is slightly larger than M1 × L1, so that the body 50 is in a slightly forward tilting state, which is beneficial for an operator to control the operation angle, and the operation is easier and more labor-saving.

In one embodiment, the dirt cup assembly 10, the motor assembly 20, and the battery pack assembly 30 all satisfy M1 × L1 — M2 × L2. That is, the body 50 is balanced forward and backward with respect to the center line of the motor assembly 20, and there is no significant tendency to topple over, so that the operator can well grasp the center of gravity of the cleaning apparatus 100 and stably perform the cleaning operation.

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 the present embodiment, the turning point of the handle 40 is disposed right 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 device 100 is lifted up through the turning point, the lifting position is substantially on the perpendicular line of the center of gravity of the body 50, and thus the weight distribution is balanced and the lifting is stable.

Alternatively, as shown in FIG. 1, the included angle A of the first portion 41 and the second portion 42 is between 90 and 150. The handle 40 is arranged in an obtuse-angle bent shape, so that an operator can conveniently put in the handle, the ergonomics are met, and the operation is smoother and more comfortable. The handle 40 may be formed in two bent linear portions, or may be formed in a circular arc shape or other comfortable curved shape. The inside of the handle 40, i.e. the hand grip, may be patterned to provide anti-slip properties.

As shown in FIG. 1, in one embodiment, when the body 50 is supported on a surface, the second portion 42 is at an angle B of between 45 and 80 to the support surface. The inclined condition of the second portion 42 of the handle 40 facilitates insertion and grasping of the operator's hand when the angle B is set between 45 ° and 80 °. Optionally, the angle B is set to 56 °, which is a comfortable operating angle for many trials and is ergonomically acceptable. Meanwhile, the height of the handle 40 may be set to be adjustable, so that it may be adjusted according to the height of the operator, so that the operator may take up the cleaning apparatus 100 more easily without bending down by a large angle.

In another embodiment, as shown in FIG. 1, the hand-held cleaning device 100 further comprises 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 substantially tangentially arranged. The arrangement makes the connection part of the suction port component 60 and the dust cup component 10 be the inclined plane of the suction port component 60, which can effectively increase the passage area of the suction port component 60 and the dust cup component, is beneficial to the suction of dust, is not easy to block and has high-efficiency dust collection.

Alternatively, as shown in fig. 1, the axis of the suction port 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 port assembly 60 and the central axes of the dirt cup assembly 10, the motor assembly 20 and the battery pack assembly 30 form a planar angle C of between 20 ° and 60 °. The angle C of the present embodiment is set between 20 and 60 to ensure the suction port assembly 60 to be in a natural inclined and drooping state, which enables effective cleaning of the floor surface and the belt cleaning surface having 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 port assembly 60 and the axis of the handle 40, especially the axis of the first portion 41 of the handle 40, are perpendicular to the central axis of the motor assembly 20 when viewed from above, so that the suction port assembly 60 and the handle 40 are not inclined in the left-right direction relative to the body 50, and the arrangement is relatively uniform.

Further, as shown in fig. 2, the dirt cup assembly 10, the motor assembly 20, and the battery pack assembly 30 are all substantially left-right symmetrical about the axis of the handle 40 when viewed from above, such that the overall cleaning device 100 is left-right symmetrical without left-right tilting.

In another embodiment, not shown, the body 50 of the cleaning device 100 is formed by sequentially traversing and coupling the dirt cup assembly 10, the motor assembly 20, and the battery pack assembly 30 instead of the body 50 of the cleaning device 100 formed by sequentially traversing and coupling the dirt cup assembly 10, the battery pack assembly 30, and the motor assembly 20, and the respective structural and positional relationships are changed simultaneously.

That is, the above-described technical effects can still be obtained by interchanging the positions of the battery pack assembly 30 and the motor assembly 20 in the above-described embodiment, with the battery pack assembly 30 as the approximate center of gravity.

Fig. 3 is a front view of a cleaning apparatus 100 according to another embodiment of the present invention in a normal state. As shown in FIG. 3, in one embodiment, the hand-held cleaning device 100 further comprises a hose assembly 70 and a floor brush 80. The form of the floor brush 80 may be any of those known in the art. Alternatively, the floor brush 80 may have functions of beating, vibrating, light sterilizing, etc. The joint pipe assembly 70 is communicated with the suction port assembly 60 and detachably connected to the suction port assembly 60, so that the two have at least a first butt joint state and a second butt joint state with axes coinciding or parallel. In the first butt state, the handle 40 is located above the ground compared with the body 50; in the second docking position, the handle 40 is positioned below the floor, which may be a floor of a house, a sofa surface, a wall surface, etc., relative to the body 50. A floor brush 80 is attached to an end of the joint pipe assembly 70 remote from the suction port assembly 60, and the floor brush 80 has a dust suction port for sucking dust. That is, the floor brush 80 directly contacts the surface to be cleaned, and dirt and dust enters the dirt cup assembly 10 through the floor brush 80, the hose attachment assembly 70, and the suction opening assembly 60. The range of operation of the cleaning apparatus 100 can be increased by the arrangement of the floor brush 80 and the hose assembly 70 to clean farther or higher places and increase the range of cleaning.

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 normal dust-sucking state after the pipe connecting assembly 70 and the floor brush 80 are attached, i.e., the first docking state. As shown in figure 4, a low cleaning angle, i.e. the second docking condition described above, can be achieved by reversing the cleaner and applying the first portion 41 of the handle 40 to a surface for cleaning. For example, the first portion 41 of the handle 40 may be attached to the ground to absorb low conditions such as the bottom of a sofa.

Thus, 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 in detail herein, many other variations and modifications can be made, consistent with the principles of the invention, which are directly determined or derived from the disclosure herein, without departing from the spirit and scope of the invention.
