Figure 1 discloses a prior art surface cleaning apparatus in which the handle assembly cannot rotate relative to the main body. Referring to fig. 2, the direction of the arrow is the direction of travel of the apparatus. Fig. 2 discloses a device comprising a body 2 and a handle assembly 1. Referring to fig. 3-12, the handle assembly 1 includes a rotating portion 11 and a grip portion 12. Of course, a connecting portion 13 connecting the rotating portion 11 and the grip portion 12 may be further included. The rotary part 11 is rotatably mounted to the body 2 or the extension rod 4 about a rotational axis O such that the handle assembly 1 can be rotated in a first plane a substantially perpendicular to the working surface B. The body 2 may be a single body, and the body 2 may further include a connecting rod 21, in which case the handle assembly 1 is rotatably mounted to one end of the connecting rod 21. The rotating portion 11 is a part of the handle assembly 1, and may be a small part or a large part, and the volume of the rotating portion 11 is not limited here, and only needs to be pivotable with respect to the main body 2 or the extension rod 4. A grip portion 12 is connected to the rotating portion 11, the grip portion 12 being configured to be gripped by a user. The connecting portion 13 is used to connect the rotating portion 11 and the connecting portion 13. The connecting portion 13 is a place which is rarely touched by a user in normal use, but may be touched by the user occasionally, but mainly plays a connecting role rather than being mainly held. The grip portion 12, the connecting portion 13, and the rotating portion 11 may be integrally formed, or may be provided separately. At least a part of the holding space is defined among the rotating portion 11, the connecting portion 13 and the holding portion 12 to facilitate the user's holding.

Referring to fig. 7 to 8, the direction of the arrow in the drawings is a direction perpendicular to the grip portion, a first plane a passing through at least a part of the grip portion 12 is defined as a predetermined plane, and a region formed by the movement of the grip portion 12 in a direction perpendicular to the axis of the grip portion 12 is defined as a first region C within the predetermined plane, and the rotation axis O is located within the first region C. The rotation axis O may be perpendicular to the first plane a and may also be at an angle to the first plane a, preferably the rotation axis O is perpendicular to the first plane a. Referring to fig. 7, the axial direction perpendicular to the grip portion 12 is better defined when the grip portion is of a relatively straight configuration. Referring to fig. 8, when the grip 12 has a certain curvature, the two ends of the grip 12 may be connected to each other, and then the direction perpendicular to the connection line is taken as the moving direction. The grip portion 12 is intended to mean a position where a user's hand is mainly or permanently held during operation, and other structures for increasing the handle shape should not be included in the grip portion 12. The predetermined plane is preferably a plane in the direction of travel of the apparatus, which is substantially perpendicular to the working surface B. The grip portion 12 is cut out of the predetermined plane, and both the grip portion 12 and the rotation axis O are included in the plane, and if the rotation portion 11 is located directly below the grip portion 12, the rotation portion 11 is also included in the plane.

Referring to fig. 9-11, the rotation axis 26 of the handle assembly 1 is disposed opposite to the grip portion 12, so as to concentrate the point of application of force at a position corresponding to the hand, i.e. when the hand naturally holds the grip portion 12, the arm, the hand and the rotation axis 26 are substantially in the same straight direction, which makes the user more labor-saving when operating the device. Especially, when the force applied to the handle assembly 1 by the main body 2 is concentrated on the rotating part 11 in the process of pushing and pulling the device, the force applied to the handle assembly 1 by the main body 2 is basically not required to be applied by the wrist of the user because the rotating part 11 is rotatable relative to the main body, and only the arm force of the user is required to be transmitted to the rotating part 11 of the handle assembly 1 through the hand, which is equivalent to that the user only performs the action of swinging the arm, and the wrist has basically no force. Therefore, the user can feel more labor-saving in the operation process.

However, in the prior art, the handle assembly 1 cannot rotate relative to the main body 2, and the joint between the handle assembly 1 and the main body 2 changes relative to the position of the hand of the user along with the back and forth movement of the device, so that the user is required to adjust the position of the hand relative to the forearm, and the device is difficult to use.

Referring to fig. 11 and 12, in one implementation of the handle assembly 1, the handle assembly 1 comprises a rotating portion 11 and a grip portion 12 that are substantially parallel, the handle assembly 1 further comprising a first connection portion 14, the first connection portion 14 connecting a first end of the grip portion 12 and a first end of the rotating portion 11. The first connection portion 14 is arc-shaped, but may have other shapes. Each of the diagrams a and b in fig. 12 has only one connecting portion.

Referring to fig. 11 and 12, in another implementation of the handle assembly 1, in addition to the first connecting portion 14, a second connecting portion 15 may be further included, and the second connecting portion 15 connects the second end of the grip portion 12 and the second end of the rotating portion 11. The second connecting portion 15 is arc-shaped, but may have other shapes. There are two connections in the diagrams c in fig. 11 and 12.

Referring to fig. 11, the connecting portion 13 includes a first connecting portion 14 and a second connecting portion 15, the first connecting portion 14 connects first ends of the rotating portion 11 and the holding portion 12, the second connecting portion 15 connects second ends of the rotating portion 11 and the holding portion 12, and the rotating portion 11, the first connecting portion 14, the holding portion 12, and the second connecting portion 15 collectively define a holding space. With two connecting portions 13, the entire handle assembly 1 can be made more stable and convenient to operate, since the user can operate the device through the connecting portions 13 except during normal use. The first connecting portion 14 and the second connecting portion 15 are each arc-shaped and form a ring shape in cooperation with the rotating portion 11 and the grip portion 12.

The grip portion 12 is configured to be inclined at an angle of not more than 20 degrees with respect to the working surface B when the handle assembly 1 is in use. It will be appreciated that the grip portion may be rotated into a position which does not differ from the work surface by more than 20 degrees, when the device is in use, regardless of how much the device is tilted relative to the work surface. Further, the grip portion 12 is configured to be substantially horizontal when the handle assembly 1 is in the use position, i.e. the grip portion may each be rotated to a position substantially parallel to a work surface. The use state is a state in which the main body 2 is inclined at 0 to 60 degrees with respect to the working surface B, and the user holds the grip portion 12 with a hand and pushes and pulls the apparatus in a relaxed state. In this state, the user can push and pull the device with the least force, which is more labor-saving.

The handle assembly 1 can be mounted to any device, and only the main body 2 of the device needs to have a certain angle relative to the working surface B during working, and a user can push and pull the main body 2 through the handle assembly 1 during working.

Referring to figure 13 there is disclosed a surface cleaning apparatus 100, the surface cleaning apparatus 100 comprising a main body 2, a cleaning head 3 and a handle assembly 1 according to any of the embodiments described above. The body 2 includes opposed proximal and distal ends 22, 23 along its length. The body 2 may include a connecting rod 21, it being understood that the connecting rod 21 is part of the body 2. The cleaning head 3 is disposed at the proximal end 22 for cleaning a surface to be cleaned. The cleaning head 3 may comprise a wiping piece such as a roller brush, a rag or the like. The cleaning head 3 can be moved repeatedly in the direction of travel to clean the surface to be cleaned. The handle assembly 1 comprises a rotary part 11 and a grip part 12, the rotary part 11 being rotatably mounted to the distal end 23 about a rotation axis O. A grip portion 12 is connected to the rotating portion 11, the grip portion 12 being configured to be gripped by a user. The rotating portion 11 is a part of the handle assembly 1, and may be a small part or a large part, and the volume of the rotating portion 11 is not limited here, and only needs to be pivotable with respect to the main body 2. The rotary portion 11 may be formed integrally with the grip portion 12, or may be provided separately from the grip portion.

Surface cleaning apparatus 100 may include one or both of a cleaning liquid supply system including a clean water tank, a supply line, and a water pump, and a soil recovery system. The dirt recovery system comprises a recovery tank and also comprises a suction motor and a suction pipeline. The clean water tank may be provided in the main body 2, and the recovery tank may be provided in the main body 2, and may also be provided in the cleaner head 3. The suction motor may be provided in the main body 2 and may also be provided in the cleaner head 3. When the clean water tank, the sewage tank and the suction motor are all arranged in the main body 2, at this time, the weight of the whole main body 2 can be heavier, and the user can be labored in the operation.

The holding part 12 is rotatably arranged at the far end 23 of the main body 2 through the rotating part 11, and the handle is rotatable relative to the main body 2 in the process of pushing and pulling the main body 2, so that the burden of a user holding the handle can be effectively reduced, and the user can drag the equipment with little force.

Referring to fig. 14-17, fig. 14 may be a first position of the user while in use, and fig. 15 may be a second position of the user while in use. The use state during normal cleaning may be that the cleaning device is pushed or pulled between the first position and the second position. To further reduce the user's effort in pushing and pulling the cleaning device, the handle assembly 1 may be further modified. The main body 2 or the extension bar 4 has an upright state (refer to fig. 13) and a use state (refer to fig. 14 and 15) with respect to the cleaning head 3, and when the main body 2 or the extension bar 4 is in the use state, the rotation section 11 is located below the grip section 12 in the vertical direction. The use state described here is a state in which the user holds the grip portion 12 with his hand and keeps a relatively relaxed state. Since the handle assembly 1 is rotatable, the device can be pushed and pulled regardless of the angle to which the handle assembly is rotated, only the force is different, and the use state refers to that the user can push and pull the device with the minimum force. In the above-mentioned usage state, the rotating portion 11 is located below the grip portion 12, where the below includes but is not limited to being located directly below the grip portion 12, and may also be slightly offset from some orientation, for example: referring to fig. 18-20, the rotating portion 11 is located directly below the grip portion. Referring to fig. 3 to 5, if the two rotary shafts 2, 6 are disposed outside the handle assembly 1, it can be understood that the rotary shaft 11 is located below the grip 12 even though the rotary shaft 11 is not located directly below the grip 12. However, if the rotating portion 11 and the grip portion 12 are placed in the same vertical plane, the rotating shaft 26 of the rotating portion 11 is located directly below the grip portion 12. With this arrangement, it is equivalent to disposing the rotation shaft 26 directly under the hand, and at this time, the user should be most labor-saving when operating the device, because the gravity on the main body 2 is concentrated at the rotation shaft 26 during the pushing and pulling process, and the rotation shaft 26 is located below the grip portion 12, and therefore, it is equivalent to carrying a heavy object with the hand, and if the handle assembly 1 cannot rotate, the gravity on the main body 2 is concentrated in front of or obliquely in front of the grip portion 12 during the pushing and pulling process, and at this time, the user needs a large force during the pushing and pulling process, just like holding things with the hand at ordinary times, and should be most labor-saving when carrying.

It will also be appreciated that, with reference to the figures, the handle assembly 1 further comprises a limit formation 25, the limit formation 25 being configured to limit the degree of rotation of the handle assembly 1 such that the degree of rotation is less than 100 degrees. Further, it may be limited to 70 degrees. Still further, it may be limited to 45 degrees.

Referring to fig. 18-20, in one implementation, the distal end 23 of the main body 2 or the extension rod 4 includes a connecting structure 24, a portion of the connecting structure 24 extends into the interior of the handle assembly 1 to be pivotally connected with the rotating portion 11 via a rotating shaft 26, and the distal end 23 is provided with a limiting structure 25 defining the rotation angle of the handle assembly 1.

Referring to fig. 3-6, in another implementation, the distal end 23 of the main body 2 or the extension rod 4 includes a connection structure 24, the connection structure 24 defines a mounting slot to be pivotably connected with the rotation part 11 through a rotation shaft 26, and the distal end 23 is provided with a limit structure 25 defining a rotation angle of the handle assembly 1.

FIG. 21 is a schematic view showing the structure of a cleaning apparatus in still another embodiment. Referring to fig. 21, the surface cleaning apparatus 100 may be a horizontal type cleaning apparatus, which includes a main body 5 and a cleaning head 3 placed on the floor, and an extension rod 4 connecting the main body 5 and the cleaning head 3, wherein the cleaning head 3 is installed at one end of the extension rod 4, and the handle assembly 1 is installed at the other end thereof, and then is communicated with the main body 5 through a hose. The handle assembly 1 may be of any of the embodiments described above.

While embodiments of the invention have been described above, it is not limited to the applications set forth in the description and the embodiments, which are fully applicable in various fields of endeavor to which the invention pertains, and further modifications may readily be made by those skilled in the art, it being understood that the invention is not limited to the details shown and described herein without departing from the general concept defined by the appended claims and their equivalents.
