Abstract
Description
Technical Field
[0001] This utility model relates to the field of rotary mop technology, specifically to a rotary mop head. Background Technology
[0002] In existing rotary mop heads, the spin-drying process in the spin-dry basket is typically achieved by pressing down on a drive rod with a threaded strip to rotate the basket, as illustrated in Chinese invention patent CN101849807A, entitled "Hand-Press Rotary Spin-Dry Mop." During rotation, the inner disc of the mop head initially encounters resistance from the spin-dry basket, redirecting the rotational motion to the outer disc containing the mop cloth. The mop cloth on the outer disc then uses friction to rotate the inner wall of the spin-dry basket, initiating its rotation – a flexible connection. However, the friction of the mop cloth is unreliable. For example, the outer diameter of the mop cloth may shrink after use, preventing proper contact with the spin-dry basket, or insufficient friction may occur during acceleration after startup, leading to loss of rotation and poor performance.
[0003] To solve the above problems, after in-depth research, the inventors proposed a rotating mop head structure in which the outer disc and the drive column of the dehydration basket are rigidly connected. Utility Model Content
[0004] In view of the deficiencies in the prior art, this utility model provides a rotating mop head to solve the technical problem of the mop head losing rotation when driving the spin-dry basket in the prior art.
[0005] As one aspect of this utility model, a rotary mop head is provided, comprising an inner disc, an outer disc, and a gear transmission assembly. The gear transmission assembly receives rotational power from a drive rod, and both the inner and outer discs are connected to the gear transmission assembly to receive this rotational power. The outer disc is provided with a drive component for rigidly connecting to a spin-dry basket. It should be noted that a rigid connection is a connection without relative motion.
[0006] In traditional rotary mop heads, the spin basket requires external force to rotate from a stationary state. Simultaneously, the spin basket exerts a reaction force on the connected inner disc, causing the outer disc to rotate first upon startup. The outer disc's rotation is then driven by the friction of the mop, which in turn rotates the spin basket. However, this friction-driven rotation is a soft connection, leading to loss of rotation and difficulty in accelerating the spin basket to a suitable speed. By incorporating a rigid drive mechanism on the outer disc, the spin basket can be directly driven, solving the problem of rotation loss in traditional rotary mop heads.
[0007] When the driving component is made of a soft material, as long as it satisfies the structure of directly driving the dehydration basket to rotate without losing rotation, it is equivalent to the inventive concept of hard connection driving without losing rotation of the present invention and will fall within the protection scope of the present invention.
[0008] In the aforementioned rotating mop head, the driving component is fixedly connected to the outer disc, and the driving component is provided with a transmission structure for rigid connection with the spin-drying basket.
[0009] In the aforementioned rotating mop head, the transmission structure is a polygonal or elliptical hole recessed in the driving member, or the transmission structure is a protruding block protruding from the driving member.
[0010] In the aforementioned rotating mop head, the drive component and the spin-dry basket are detachably connected. This detachment is necessary for easy insertion and removal.
[0011] In the aforementioned rotating mop head, the outer disc is provided with fixing holes, and the driving component is fixed to the fixing holes of the outer disc by screws or rivets.
[0012] The aforementioned rotating mop head includes a gear transmission assembly comprising a drive gear and planetary gears. The planetary gears are multiple and distributed on the outer edge of the drive gear. The planetary gears mesh with the drive gear and are fitted onto the positioning pins on the inner side of the outer disc.
[0013] In the aforementioned rotating mop head, the inner sidewall of the inner disc is provided with internal teeth, and the drive gear is meshed with the internal teeth of the inner disc through the planetary gear.
[0014] In the aforementioned rotating mop head, one end of the drive gear is connected to a drive rod that provides rotational force, and the other end of the drive gear is provided with a lower edge.
[0015] The aforementioned rotating mop head also includes a retaining clamp, one end of which is sleeved and locked onto the lower edge of the drive gear, and the other end is fixedly connected to the inner disc through a rotating snap-fit structure.
[0016] This utility model also provides a rotary mop assembly, which includes the aforementioned rotary mop head and a spin-dry basket drive column. The spin-dry basket drive column is provided with a connecting part that can be adapted to the shape of the transmission structure for connection. When the transmission structure is a polygonal hole recessed in the drive member, the connecting part is a polygonal column; when the transmission structure is a protrusion protruding in the drive member, the connecting part is a recessed groove. The transmission structure can drive the spin-dry basket to rotate through the connecting part.
[0017] The aforementioned rotating mop assembly also includes a fixed post disposed inside the rotating mop bucket. The drive component has a hole larger than the fixed post, which is located outside the edge of the fixed post during rotation.
[0018] Existing rotary mop buckets include a spin-dry basket drive column and a fixed column. During rotation, this fixed column locks the inner disc, allowing the outer disc to rotate and wash the mop cloth attached to it. To allow the transmission structure on the drive component of this invention to rotate smoothly on the fixed column, the drive component has a hole larger than the fixed column. This hole is located on the outer edge of the fixed column during rotation and does not obstruct the rotation of the outer disc. This hole can be a polygonal hole for driving the connecting part.

[0026] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.
[0027] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.
[0028] As one aspect of this utility model, such as Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown, a rotating mop head is provided, including an inner disc 1, an outer disc 2, and a gear transmission assembly. The gear transmission assembly receives the rotational power of a drive rod 10. Both the inner disc 1 and the outer disc 2 are connected to the gear transmission assembly to receive the rotational power. The outer disc 2 is provided with a drive element 3 for rigidly connecting to the spin-dry basket.
[0029] In traditional rotary mop heads, the spin basket requires external force to rotate from a stationary state. Simultaneously, the spin basket exerts a reaction force on the inner disc 1 connected to it, causing the outer disc 2 to rotate first upon startup. The rotation of the outer disc 2 drives the spin basket through the friction of the mop. However, this friction-driven rotation is a soft connection, which can cause loss of rotation, making it difficult for the spin basket to accelerate to a suitable speed. By incorporating a rigid drive component 3 on the outer disc 2, it can directly drive the spin basket, solving the technical problem of loss of rotation in traditional rotary mop heads.
[0030] In some embodiments, the drive component 3 is fixedly connected to the outer disk 2, and the drive component 3 is provided with a transmission structure for rigid connection with the dehydration basket.
[0031] More specifically, a drive component 3 is fixed to the outer disk 2 and moves synchronously with the outer disk 2; at the same time, a transmission structure is used to rigidly connect with the dehydration basket to drive it, in order to solve the problem of loss of rotation.
[0032] In some embodiments, the transmission structure is a polygonal hole 4 or an elliptical hole recessed in the driving member 3, or the transmission structure is a protruding block protruding from the driving member 3.
[0033] The polygonal hole 4 recessed on the driving component 3 can be a quadrilateral or multi-sided hole, and the polygonal hole 4 is adapted to drive the dehydration basket driving column 5; the protruding block protruding on the driving component 3 can be a protruding columnar structure, which is inserted into the dehydration basket driving column 5 or the bottom wall or side wall of the dehydration basket.
[0034] The protruding block can also be configured as a plug-in post offset from the rotation center of the drive component 3. This plug-in post can be inserted into the bottom wall of the dehydration basket to drive the dehydration basket to rotate.
[0035] When the transmission structure is an elliptical hole recessed in the drive member 3, a structure that can extend into the elliptical hole is provided on the dehydration basket to drive the dehydration basket to rotate.
[0036] In some embodiments, the drive unit 3 is detachably connected to the dehydration basket. Easy disassembly is necessary for convenient insertion and removal.
[0037] In some embodiments, the outer disk 2 is provided with a fixing hole 6, and the driving component 3 is fixed to the fixing hole 6 of the outer disk 2 by screws or rivets.
[0038] In some embodiments, the gear transmission assembly includes a drive gear 7 and planetary gears 8. There are multiple planetary gears 8 distributed on the outer edge of the drive gear 7. The planetary gears 8 mesh with the drive gear 7 and are fitted onto the positioning pins 9 on the inner side of the outer disk 2.
[0039] In some embodiments, the inner sidewall of the inner disk 1 is provided with internal teeth, and the driving gear 7 is adapted to mesh with the internal teeth of the inner disk 1 through the planetary gear 8.
[0040] The drive gear 7 receives the rotational force from the drive rod 10, driving the planetary gear 8 to rotate on the positioning post 9. The planetary gear 8 meshes with the internal teeth of the inner disk 1, driving the inner disk 1 to rotate. When the outer disk 2 is stationary, the inner disk 1 rotates; when the inner disk 1 is stationary, the outer disk 2 rotates.
[0041] In some embodiments, one end of the drive gear 7 is connected to a drive rod 10 that provides rotational force, and the other end of the drive gear 7 is provided with a lower edge 11.
[0042] In some embodiments, a retaining clamp 12 is also included, one end of which is sleeved and locked onto the lower edge 11 of the drive gear 7, and the other end is fixedly connected to the inner disk 1 by a rotary snap-fit structure.
[0043] like Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown, this utility model also provides a rotary mop assembly, which includes the aforementioned rotary mop head and a spin-dry basket drive column 5. The spin-dry basket drive column 5 is provided with a connecting part 13 that can be adapted to the shape of the transmission structure for connection. When the transmission structure is a polygonal hole 4 recessed in the drive member 3, the connecting part 13 is a polygonal column; when the transmission structure is a protruding block protruding in the drive member 3, the connecting part 13 is a recessed groove. The transmission structure can drive the spin-dry basket to rotate through the connecting part 13.
[0044] The aforementioned rotating mop assembly also includes a fixed post 14 disposed inside the rotating mop bucket. The drive component 3 has a hole larger than the fixed post 14, which is located outside the edge of the fixed post 14 during rotation.
[0045] Existing rotary mop buckets, besides containing a spin-dry basket drive column 5, also include a fixing column 14. During rotation, this fixing column 14 is used to lock the inner disc 1, allowing the outer disc 2 to rotate and wash the mop cloth connected to it. To allow the transmission structure on the drive component 3 of this invention to rotate smoothly on the fixing column 14, the drive component 3 is provided with a hole larger than the fixing column 14. This hole is located outside the edge of the fixing column 14 during rotation and will not obstruct the rotation of the outer disc 2. This hole can be a polygonal hole 4 for driving the connecting part 13.
