[0034] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, wherein the accompanying drawings constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0035] In the description of the embodiments of the present invention, it should be noted that, unless otherwise specified or limited, the term "connected" should be understood in a broad sense. For example, it can mean a fixed connection, a detachable connection, or an integral connection. It can be a mechanical connection, an electrical connection, a direct connection, or an indirect connection through an intermediate medium. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0036] The terms "top," "bottom," "above," "below," and "on" used throughout the description refer to relative positions of components of a device, such as the relative positions of top and bottom substrates within a device. It will be understood that devices are multifunctional regardless of their orientation in space.

[0037] For the sake of convenience, in the embodiment of the present invention, the direction of the suction port of the main unit 12 of the cleaning device is the front in the embodiment of the present invention, and correspondingly, the opposite direction is the rear. Figure 1 As shown, both ends of the handle of the existing cleaning device are connected to the main body 12, and the gripping space formed therein has an annular side wall whose size cannot be adjusted, which affects the user's grip on the handle.

[0038] Example 1

[0039] like Figure 3 、 Figure 4 As shown, an embodiment of the present invention provides a handle for a cleaning device, comprising a grip portion, one end of which is connected to the rear portion of a main body 12 of the cleaning device, and the other end being a free end; the grip portion at least partially surrounds the rear portion of the main body 12 of the cleaning device, forming a semi-enclosed space. It should be noted that in the embodiment of the present invention, the semi-enclosed space refers to a space for holding formed between the grip portion and the main body 12 of the cleaning device, which has no annular sidewall, that is, no hole or aperture, so as to eliminate the restriction of the annular sidewall on the user's grip position and posture when holding the handle, so that the user does not need to frequently change the position of the grip portion. In addition, the projection of the grip portion on the cross-section of the cleaning device passes through the projection of the rear portion of the cleaning device on the cross-section of the cleaning device, that is, the grip portion extends from the outside of the rear portion of the main body 12 of the cleaning device across the rear portion of the main body 12 of the cleaning device, so that a portion of the grip portion is located on one side of the main body 12 of the cleaning device, a portion is located behind the main body of the cleaning device, and a portion is located on the other side of the main body 12 of the cleaning device. The user can adjust the grip position according to actual needs.

[0040] In an embodiment of the present invention, the holding portion includes a first holding structure 1, a second holding structure 2, and a connecting structure 3 connected in sequence; the connecting structure 3 is fixedly connected to the side wall of the cleaning device; the second holding structure 2 is fixedly connected to the connecting structure 3, and the second holding structure 2 is bent toward the axis of the cleaning device; the first holding structure 1 is fixedly connected to the second holding structure 2, and the axis of the first holding structure 1 is parallel to the axis of the main body 12 of the cleaning device and extends toward the front end of the cleaning device. The connecting structure 3 is connected to the side wall of the cleaning device and extends backward to connect with the second holding structure 2. The second holding structure 2 bends and crosses the rear of the cleaning device and extends forward to connect with the first holding structure 1, so that at least a portion of the first holding structure 1 is located on the side of the main body 12 of the cleaning device and is suspended in the air to ensure that the holding space is a semi-enclosed space.

[0041] In order to facilitate production and processing and user holding, in the embodiment of the present invention, the holding portion is an integrated rod structure with unchanged cross-sectional shape and size, and the second holding structure 2 is a bent and / or folded rod structure, and the cumulative bending and / or bending angle at both ends is 180°, that is, both ends of the second holding structure 2 are facing forward, and both ends of the second holding structure 2 are located on the same cross-section of the cleaning device. Exemplarily, the second holding structure 2 can be a semicircular bent rod, or a door-shaped square folding rod; a first holding space is defined between the first holding structure 1 and the cleaning device, and a second holding space is defined between the second holding structure 2 and the cleaning device; the first holding space and the second holding space are both open spaces without closed-loop side walls, that is, the aforementioned semi-enclosed space.

[0042] In an embodiment of the present invention, the second gripping structure 2 is provided with a rotating component, the rotation axis of which is perpendicular to the plane formed by the axis of the connecting structure 3 and the axis of the cleaning device main body 12. When the two parts of the second gripping structure 2 rotate relative to the rotating component, the size of the first gripping space and the second gripping space can be adjusted to facilitate the user's grip on the grip portion. In addition, the user can adjust the pitch posture of the cleaning device by rotating the rotating component without adjusting the grip position, making it easier and more convenient for the user to use the cleaning device. The rotating component is provided with a damper that can maintain the rotation angle of the rotating component unchanged in the absence of external forces.

[0043] In this embodiment of the present invention, the connecting structure 3 is a retractable rod. When the connecting structure 3 is relatively fixed to the cleaning device main body 12, the second gripping structure 2 can be moved closer to or further away from the cleaning device main body 12 by the extension and contraction of the connecting structure 3, thereby adjusting the size of the first gripping space and the second gripping space. The connecting structure 3 is provided with a clamping structure, and the clamping block of the clamping structure is used to limit the extension and contraction of the connecting structure 3, thereby maintaining a constant extension and contraction length.

[0044] When the user holds the handle, the relative position between the grip portion and the side end or the rear end of the main unit 12 can be adjusted, and the user does not need to frequently change the position of holding the handle portion.

[0045] like Figure 2 、 Figure 3 As shown, in this embodiment of the present invention, the grip portion is secured to the main body 12 of the cleaning device via a securing portion. Specifically, the handle of the cleaning device further includes a securing portion, which includes a first securing structure 4 and a second securing structure 5 disposed on a side wall of the cleaning device. The connecting structure 3 is connected to the first securing structure 4 and the second securing structure 5. By simultaneously securing the first securing structure 4 and the second securing structure 5, the rod-shaped connecting structure 3 can be secured to the main body 12 of the cleaning device.

[0046] To improve the connection performance between the gripping portion and the fixing portion, in an embodiment of the present invention, the first fixing structure 4 is provided with a through hole parallel to the axis of the cleaning device, and the second fixing structure 5 is provided with a blind hole coaxial with the through hole; the connecting structure 3 passes through the through hole and into the blind hole; the second gripping structure 2 passes through the through hole, and both the second gripping structure 2 and the connecting structure 3 are at least partially located within the through hole. In this embodiment of the present invention, the position of the connecting structure 3 relative to the cleaning device main body 12 is restricted by the blind hole and the through hole, and the radial position of the connecting structure 3 itself is restricted by the blind hole, thereby restricting the position of the gripping portion relative to the cleaning device main body 12 through the fixing portion.

[0047] Since the holding portion adopts an integrated rod structure, in the embodiment of the present invention, the cross-sectional shape and size of the through hole and the blind hole and the cross-sectional shape and size of the holding portion are such that the fixing portion and the holding portion are fixed by friction between the through hole and the blind hole and the holding portion. In order to further improve the fixing effect, adhesive can be filled between the outer surface of the holding portion and the inner surface of the through hole and the blind hole, or fixed by screws or other components.

[0048] In order to facilitate limiting the circumferential relative position between the fixing portion and the connecting structure 3 , in the embodiment of the present invention, the cross-sectional shape of the holding portion is an ellipse, an oblong, or a rectangle with chamfered corners.

[0049] The end of the second gripping structure and both ends of the connecting structure 3 are respectively placed inside the first fixing structure 4 and the second fixing structure 5, so that the connecting structure 3 is connected to the cleaning device host 12, which can improve the connection performance between the handle and the host 12.

[0050] When the cleaning device is not in use, it should be placed stably on a flat surface. In this embodiment of the present invention, the first fixing structure 4 is provided with a first protrusion 6; the second fixing structure 5 is provided with a second protrusion 7. The top of the first protrusion 6 and the top of the second protrusion 7 are coplanar and define a support reference plane. When the cleaning device is placed on a flat surface, the first protrusion 6 and the second protrusion 7 serve as a support structure, supporting the cleaning device on the plane. To prevent the cleaning device from tipping over on the plane, in this embodiment of the present invention, the projection of the center of gravity of the cleaning device on the support reference plane is located between the top of the first protrusion 6 and the top of the second protrusion 7.

[0051] Example 2

[0052] like Figure 5 As shown, an embodiment of the present invention provides a cleaning device, wherein the handle of the cleaning device is the handle of the cleaning device in Example 1; the cleaning device also includes a main unit 12; a dust cup 8, a motor assembly 9, and a power supply assembly 10 are provided within the main unit 12; a filter assembly 11 is provided within the dust cup 8; and the power supply assembly 10 includes multiple power supply structures, which are arranged around the motor assembly 9. The fixing portion is fixed to the side wall of the main unit 12, the connection structure 3 of the handle is arranged parallel to the circumference of the main unit 12, and the second holding structure 2 spans the rear of the main unit 12. The semi-enclosed space mentioned above is formed between the gripping portion of the handle and the side and rear ends of the main unit 12.

[0053] It should be noted that the connection between the fixing portion and the housing of the host 12 is an integral structural connection or a detachable connection.

[0054] Example 3

[0055] An embodiment of the present invention provides a method for assembling a cleaning device handle, and the method for assembling a cleaning device handle is used to assemble the handle of Example 1 used in Example 2;

[0056] The assembly method of the cleaning device handle includes:

[0057] Pass the holding portion through the through hole of the first fixing structure 4 until the front end of the connecting structure 3 passes through the blind hole of the second fixing structure 5, and the second holding structure 2 is partially inserted into the through hole of the first fixing structure 4; fix the outer wall of the holding portion to the inner wall of the through hole and the blind hole.

[0058] To sum up, the embodiments of the present invention provide a handle for a cleaning device, a cleaning device and an assembly method. The present invention adopts an open holding space. When the user holds the handle, the relative position between the holding portion and the side end or the rear end of the main unit can be adjusted, and the user does not need to frequently change the position of holding the handle; the present invention fixes the holding portion through a first fixing structure and a second fixing structure, and passes the holding portion through the first fixing structure and the second fixing structure, which can increase the connection performance between the handle and the main unit; the present invention is provided with a first protrusion and a second protrusion, so that when the cleaning device is placed horizontally on a plane, it can have a good supporting effect.
