[0026] The following description of the present invention, with reference to the accompanying drawings, is provided to facilitate a more comprehensive understanding of the various embodiments of the present invention as defined in the claims and their equivalents. The description includes various specific details to assist understanding, but these details should be construed as merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications may be made to the various embodiments described herein without departing from the scope and spirit of the present invention.

[0027] In the description of the present invention, descriptions of directions, such as up, down, front, back, left, right, etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as a limitation on the present invention.

[0028] It will be understood that when one element (e.g., a first element) is “connected” to another element (e.g., a second element), the element may be directly connected to the other element or an intervening element (e.g., a third element) may be present between the element and the other element.

[0029] The embodiment of the present invention provides a handheld floor scrubber with adjustable angle, such as Figure 1 and Figure 2As shown, the floor scrubber includes a main body 100, a handle assembly 200, a caster bracket 300, a caster 400 fixed to the caster bracket 300, and a fastening assembly 500. The handle assembly 200 includes a connecting bracket 210 and a support rod 220. The lower end of the support rod 220 is connected to the connecting bracket 210. The support rod 220 can be directly grasped by the user, or the support rod 220 is provided with a handle, a protective cover, or other graspable components, which the user can grasp.

[0030] The lower end of the connecting bracket 210 is connected to the scrubber body 100, and the upper end of the connecting bracket 210 is rotatably connected to the caster bracket 300. This allows the angle between the connecting bracket 210 and the caster bracket 300 to be changed, and the angle of the support rod 220 to be changed accordingly. This adapts to the usage habits or height differences of different users, making it easier for users to use the scrubber of this embodiment. The fastening assembly 500 is provided on the connecting bracket 210 and the caster bracket 300 and is used to lock the connecting bracket 210 and the caster bracket 300 together or loosen the connecting bracket 210 and the caster bracket 300.

[0031] When it is necessary to adjust the angle between the connecting bracket 210 and the caster bracket 300, the connecting bracket 210 and the caster bracket 300 are loosened by the fastening assembly 500, so that the loose connecting bracket 210 and the caster bracket 300 can rotate relative to each other to change the angle; after adjusting to a suitable angle, the connecting bracket 210 and the caster bracket 300 are locked together by the fastening assembly 500, so that the loose connecting bracket 210 and the caster bracket 300 are difficult to rotate relative to each other, and the connecting bracket 210 and the caster bracket 300 can maintain the adjusted angle for stable use.

[0032] In some embodiments, as Figure 2-5 As shown, the fastening assembly 500 includes a tensioning head 510, a screw and a limiting nut 520. The connecting bracket 210 and the caster bracket 300 are both provided with through holes 201 that are connected to each other. The screw is fixed on the tensioning head 510, and the screw passes through the through holes 201 of the connecting bracket 210 and the caster bracket 300. The limiting nut 520 is sleeved on the screw. The tensioning head 510 and the limiting nut 520 are respectively located on the side where the connecting bracket 210 and the caster bracket 300 are away from each other. Specifically, the tensioning head 510 can be located on the side of the caster bracket 300 away from the connecting bracket 210, and the limiting nut 520 is located on the side of the connecting bracket 210 away from the caster bracket 300.

[0033] When the screw and the limiting nut 520 are tightened, the tensioning head 510 and the limiting nut 520 clamp the connecting bracket 210 and the caster bracket 300, thereby locking the connecting bracket 210 and the caster bracket 300 together. When the screw and the limiting nut 520 are loosened, the tensioning head 510 and the limiting nut 520 release the clamping of the connecting bracket 210 and the caster bracket 300. The tensioning head 510 not only clamps the connecting bracket 210 but also allows the user to manually hold the connecting bracket 210, thereby saving effort and facilitating operation when tightening the screw.

[0034] Furthermore, the fastening assembly 500 includes two toothed discs 530. Each toothed disc 530 is provided with a through-hole for a screw and / or a limit nut 520 to pass through. The screw can pass through the through-holes of both toothed discs 530, or the limit nut 520 can pass through the through-holes of both toothed discs 530, or the screw can pass through the through-hole of one toothed disc 530 and the limit nut 520 can pass through the through-hole of the other toothed disc 530. The two toothed discs 530 are respectively fixed to the connecting bracket 210 and the caster bracket 300, and the two toothed discs 530 are respectively located between the connecting bracket 210 and the caster bracket 300. When the connecting bracket 210 and the caster bracket 300 are locked together, the two toothed discs 530 engage with each other to further restrict relative rotation of the connecting bracket 210 and the caster bracket 300, thereby enhancing the locking effect of the connecting bracket 210 and the caster bracket 300.

[0035] In some embodiments, as Figure 2-5 As shown, the through hole 201 of the connecting bracket 210 is a square hole, and the limiting nut 520 includes a square insert 521, which is inserted into the through hole 201 of the connecting bracket 210. When the whole machine is assembled, the installation process of the limiting nut 520 can be reduced. When the locking head 510 is screwed, the square insert 521 will not rotate with the locking head 510, and the locking head 510 can be screwed smoothly, which is convenient for operation. The limiting nut 520 is not easy to loosen from the connecting bracket 210.

[0036] In this embodiment, the square insert 521 can be integrally formed with other parts of the limiting nut 520 to facilitate manufacturing.

[0037] In some embodiments, as Figure 2-5 As shown, the tensioning head 510 includes a rotating handle 511. The rotating handle 511 is larger in size and can provide a greater torque. The user holds the rotating handle 511 to rotate the tensioning head 510, which is more labor-saving to operate.

[0038] In some embodiments, as Figure 2As shown, the connecting bracket 210 includes a transverse arm 212 and two connecting arms 211. The upper ends of the two connecting arms 211 are respectively connected to the two ends of the transverse arm 212, forming a U-shaped structure. The lower ends of the two connecting arms 211 are connected to the scrubber body 100, and the lower end of the support rod 220 is connected to the transverse arm 212. The caster bracket 300 includes two support rods 310 and connecting rods 320 respectively connected to the two support rods 310, forming an "H"-shaped structure. Two casters 400 are provided. The two casters 400 are respectively fixed to the lower ends of the two support rods 310, and the upper ends of the two support rods 310 are respectively rotatably connected to the two connecting arms 211. The fastening assembly 500 is arranged on the connecting arms 211 and the support rod 310 connected to each other. Since there are two groups of connecting arms 211 and the support rod 310 connected to each other, the fastening assembly 500 can be arranged on only one group of the connecting arms 211 and the support rod 310, or the fastening assembly 500 can be arranged on both groups of the connecting arms 211 and the support rod 310.

[0039] In this embodiment, two casters 400 are provided, which can more stably support the floor scrubber body 100. Two corresponding support rods 310 and connecting arms 211 are provided to enhance the structural strength of the connection.

[0040] In some embodiments, as Figure 1 and Figure 2 As shown, the handle assembly 200 also includes a connecting base 230 and two handles 240. The connecting base 230 is connected to the upper end of the support rod 220. The two handles 240 are respectively fixed on both sides of the connecting base 230. When in use, the user can hold the two handles 240 with both hands, which is more comfortable to use and more convenient to operate.

[0041] In some embodiments, as Figure 1 、 Figure 2 and Figure 6 As shown, the floor scrubber body 100 includes an upper shell 110, a drive mechanism 120, a load mounting plate 130 and a cleaning tool 140. The upper shell 110 is located above the load mounting plate 130. The drive mechanism 120 is fixed in the upper shell 110 and connected to the load mounting plate 130. The drive mechanism 120 is used to drive the load mounting plate 130 to rotate. The cleaning tool 140 is fixed on the load mounting plate 130. The lower end of the connecting bracket 210 is connected to the upper shell 110.

[0042] When the driving mechanism 120 drives the load mounting plate 130 to rotate, the cleaning tool 140 is driven to rotate accordingly, and the cleaning tool 140 rubs against the ground to clean the ground. The cleaning tool 140 can be a cleaning pad, a brush, a cleaning cloth, etc.

[0043] In some embodiments, the lower end of the connecting bracket 210 may be rotatably connected to the floor scrubber body 100 , or may be fixedly connected to the floor scrubber body 100 .

[0044] The terms and words used in the above description and claims are not limited to their literal meanings, but are merely used by the applicant to enable a clear and consistent understanding of the present invention. Therefore, it should be clear to those skilled in the art that the above description of various embodiments of the present invention is provided for illustration only and is not intended to limit the present invention as defined in the appended claims and their equivalents.
