Description

Technical Field

[0001] This utility model relates to the field of cleaning tools technology, specifically to a mop rotating structure. Background Technology

[0002] Floor cleaning is a basic requirement for environmental maintenance, and mops, as a core cleaning tool, have become widely used. Currently, mainstream mops adopt a rotary wringing design, which drives the cleaning head to rotate at high speed by driving the rotating rod on the mop handle. Using centrifugal force, the cleaning head is efficiently dehydrated, solving the problems of traditional mops being difficult to wring out and leaving a lot of water residue.

[0003] However, existing spin-dry mops have significant drawbacks: the cleaning head is usually directly and fixedly connected to or linked with the rotating rod of the mop handle. To achieve stable spin-drying of the cleaning head, the matching cleaning bucket must have a specially designed spin-drying base adapted to the structure of the cleaning head. This spin-drying base needs to have positioning, limiting, and transmission adaptation functions to ensure that the cleaning head does not shift or shake during high-speed spin-drying. This directly leads to: a more complex cleaning bucket structure, requiring the design of an adaptation structure based on the size and rotation trajectory of the cleaning head, increasing design difficulty and manufacturing costs; and dead angles such as gaps and grooves in the spin-drying base, making it easy for wastewater and impurities spun off from the cleaning head to remain, which are difficult to clean with regular rinsing. Long-term use can easily breed bacteria and produce odors, significantly increasing the maintenance difficulty of the cleaning bucket and reducing the user experience. Utility Model Content

[0004] In view of this, the present invention proposes a mop rotating structure, a mop, and a mop assembly to simplify the structure of the cleaning bucket.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A mop rotating structure, comprising:

[0007] A dehydration seat, comprising a dehydration seat body and a guide sleeve fixedly disposed at the center of the top surface of the dehydration seat body and extending upward therefrom, wherein a guide hole is provided through the center of the dehydration seat body along the axial direction, and guide ribs are evenly distributed along the circumferential direction on the inner peripheral wall of the guide hole.

[0008] Pressing sleeve, which is slidably fitted onto the upper part of the guide sleeve;

[0009] The spiral rod has an outer spiral groove that cooperates with a guide rib, so that the spiral rod is rotatably and liftably installed in the dehydration seat. The top end of the spiral rod is rotatably connected to the center of the inner top surface of the pressing sleeve.

[0010] An elastic reset element is provided, which is arranged around the spiral rod inside the guide sleeve, and the top end of the reset spring abuts against the inner top surface of the pressing sleeve, and the bottom end of the reset spring abuts against the top surface of the dehydration seat body.

[0011] And a cleaning component, which is movably abutted against the bottom surface inside the edge of the dehydration seat and connected to the bottom end of the screw rod.

[0012] To better achieve the above technical solution, optionally, the cleaning component includes a cleaning head housing, a one-way actuator, and an end cap. The cleaning head housing has an assembly cavity with a bottom opening at its center. The one-way actuator is disposed in the assembly cavity in a manner that allows it to rotate in both directions and drive the cleaning head housing to rotate in one direction. The spiral rod movably passes through the center of the top surface of the cleaning head housing and is fixedly connected to the driving part of the one-way actuator. The end cap is fixedly closed at the bottom opening of the assembly cavity.

[0013] Optionally, the unidirectional actuator includes a drive disk and a ball bearing. The outer circumferential surface of the drive disk is uniformly provided with a plurality of dovetail notches. The ball bearing is placed in the dovetail notches, and when the drive disk rotates, the ball bearing abuts against the inner wall of the assembly cavity due to the reduced gap, so that the cleaning head housing can only rotate in one direction due to the combined restriction of the ball bearing and the dovetail notches.

[0014] Optionally, the number of dovetail notches and ball bearings are both three, and they are set in a one-to-one correspondence.

[0015] Optionally, the center of the cleaning head housing is recessed upward to form an assembly cavity.

[0016] Optionally, the outer edge of the cleaning head housing extends downward to form an outer retaining ring, and the inner circumferential wall of the outer retaining ring is fixedly provided with reinforcing ribs at intervals.

[0017] Optionally, the top end of the spiral rod is provided with a first connecting part that cooperates with the pressing cylinder, the first connecting part being a cylindrical structure, and the bottom end of the spiral rod is provided with a second connecting part that cooperates with the drive disc, the second connecting part being a flat structure.

[0018] Optionally, a weight-reducing groove is provided on the inner side of the outer edge of the dehydration seat body.

[0019] A mop, comprising the mop rotating structure as described in any one of the claims, further comprising a handle and a cleaning head, the cleaning head being detachably snapped into a cleaning head housing, and the handle being fixedly mounted to the top of a pressing sleeve.

[0020] A mop assembly includes the mop described above, and also includes a cleaning bucket, the cleaning bucket having a spin-drying bucket, the top of the spin-drying bucket having an annular support 711 that cooperates with a dehydration seat, the annular support 711 being used for the annular support.

[0021] The beneficial effects of this utility model are:

[0022] This utility model discloses a mop rotating structure. By cooperating with the dehydration seat and the annular support seat, the cleaning bucket only needs to be equipped with one annular support seat to realize the rotation drive of the cleaning components. This reduces the internal structure of the cleaning bucket, which not only reduces the manufacturing cost of the cleaning bucket, but also avoids the problem of dirt and grime accumulating in traditional complex structures, making it easier for users to clean the cleaning bucket from all angles.

[0023] This utility model discloses a mop rotation structure that utilizes a one-way driver to ensure that the cleaning head housing is driven to rotate only during the downward movement of the pressing sleeve, and does not rotate in the opposite direction with the screw rod during the reset process. This allows the rotation time to be extended by utilizing the rotational inertia of the cleaning head, enabling the cleaning head to fully dry the water under the action of centrifugal force. At the same time, it can avoid fiber entanglement caused by the reverse rotation of the cleaning head during the reset process, thereby extending the service life of the cleaning head.

Detailed Implementation

[0034] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. Identical components are indicated by the same reference numerals.

[0035] Example 1

[0036] Please see Figures 1 to 8 This utility model discloses a mop rotating structure, including a wringer seat 10, a pressing sleeve 20, an elastic reset member 40, and a cleaning component.

[0037] like Figures 2-4 As shown, the dehydration seat 10 includes a dehydration seat body 101 and a guide sleeve 102 fixedly disposed at the center of the top surface of the dehydration seat body 101 and extending upward. The dehydration seat body 101 has a disc-shaped structure. A guide hole 103 is provided through the center of the dehydration seat body 101 along the axial direction. Guide ribs 104 are evenly distributed along the circumferential direction on the inner peripheral wall of the guide hole 103.

[0038] Specifically, the guide sleeve 102 and the dehydration seat body 101 are an integral structure. The inner diameter of the guide hole 103 is smaller than the inner diameter of the guide sleeve 102, so that the top surface of the dehydration seat body 101 and the part located inside the guide sleeve 102 form a support surface.

[0039] like Figure 1 As shown, the pressing sleeve 20 is slidably fitted onto the upper part of the guide sleeve 102; as Figure 3 and Figure 4 As shown, the outer spiral groove of the spiral rod 30 cooperates with the guide rib 104, so that the spiral rod 30 is set in the dehydration seat 10 in a rotatable and liftable manner, and the top end of the spiral rod 30 is rotatably connected to the center of the inner top surface of the pressing sleeve 20.

[0040] Specifically, there are three guide ribs 104, and correspondingly three outer spiral grooves on the spiral rod 30. The outer spiral grooves and guide ribs 104 are matched one-to-one, so that the spiral rod 30 rotates and rises and falls along the extension direction of the outer spiral grooves. The elastic reset member 40 is arranged around the spiral rod 30 inside the guide sleeve 102, and the top end of the reset spring abuts against the inner top surface of the pressing sleeve 20, and the bottom end of the reset spring abuts against the support surface. The elastic reset member 40 is preferably a compression spring. The cleaning component is movably abutted against the bottom surface inside the edge of the dehydration seat 10 and connected to the bottom end of the spiral rod 30.

[0041] The working principle of the mop rotation structure in this embodiment is as follows: The bottom surface of the outer edge of the spin-drying seat 10 is fixedly pressed against the annular support seat 711 (the annular support seat 711 can be fixed on the cleaning bucket 70), so that the cleaning component is suspended. When the pressing sleeve 20 is pressed down, the pressing sleeve 20 slides axially along the guide sleeve 102, driving the spiral rod 30 to move downward synchronously. Since the outer spiral groove of the spiral rod 30 and the guide rib 104 form a spiral pair, the guide rib 104 generates a circumferential constraint force on the spiral groove, forcing the spiral rod 30 to rotate around its own axis while descending axially, thereby converting the axial force into a rotational torque and transmitting it to the cleaning component, thereby driving the cleaning component to rotate. Meanwhile, the elastic reset member 40 is compressed and stores elastic potential energy during the pressing process. When the pressing sleeve 20 is released, the elastic potential energy is released, pushing the pressing sleeve 20 to rise axially, driving the spiral rod 30 to rotate in the opposite direction and reset, realizing the cycle of pressing-rotating-reset.

[0042] The mop rotation structure of this embodiment adopts a helical pair drive, which ensures that the pressing stroke and the rotation angle of the cleaning component are linearly correlated. Users can adjust the rotation speed of the cleaning component by controlling the pressing force and stroke, thereby controlling the spin-drying efficiency. The elastic reset member 40 is arranged around the helical rod 30, so that the reset force is evenly distributed along the axis of the helical rod 30, avoiding tilting and jamming of the pressing sleeve 20 during reset, and improving the smoothness of operation. Through the cooperation of the spin-drying seat 10 and the annular support seat 711, the cleaning bucket 70 only needs to be equipped with one annular support seat 711 to realize the rotation drive of the cleaning component, thereby reducing the internal structure of the cleaning bucket 70. This not only reduces the manufacturing cost of the cleaning bucket 70, but also avoids the problem of dirt and grime accumulating in traditional complex structures, making it easier for users to clean the cleaning bucket 70 from all angles.

[0043] like Figure 2As shown, the cleaning assembly includes a cleaning head housing 51, a one-way actuator, and an end cap 54. The cleaning head housing 51 has a centrally located assembly cavity 511 with a bottom opening. The one-way actuator is positioned within the assembly cavity 511, allowing bidirectional rotation and unidirectional drive of the cleaning head housing 51. A spiral rod 30 movably passes through the center of the top surface of the cleaning head housing 51 and is fixedly connected to the drive portion of the one-way actuator. The end cap 54 is fixedly fitted over the bottom opening of the assembly cavity 511. The one-way actuator ensures that the cleaning head housing 51 is only driven to rotate during pressing and does not rotate in the opposite direction with the spiral rod 30 during the reset process. This allows the rotational inertia of the cleaning head 62 to extend the rotation time, enabling the cleaning head 62 to thoroughly dry the water under centrifugal force. Simultaneously, it avoids fiber entanglement caused by the reverse rotation of the cleaning head 62 during the reset process, thereby extending the service life of the cleaning head 62.

[0044] like Figure 5 and Figure 6 As shown, the unidirectional actuator includes a drive disk 52 and a ball bearing 53. The outer circumferential surface of the drive disk 52 is uniformly provided with a number of dovetail notches 521. The ball bearing 53 is placed in the dovetail notches 521. When the drive disk rotates, the ball bearing 53 abuts against the inner wall of the assembly cavity 511 due to the reduced gap. This restricts the cleaning head housing 51 to rotate only in one direction due to the combined restriction of the ball bearing 53 and the dovetail notches 521.

[0045] Specifically, the width of the dovetail notch 521 gradually decreases from one end to the other to form a wedge-shaped space. When the drive disc 52 rotates forward with the screw rod 30 (rotation direction during the pressing process), the ball bearing 53 moves towards the narrow end of the dovetail notch 521 under the action of centrifugal force and friction, and finally gets stuck between the inner wall of the dovetail notch 521 and the inner wall of the assembly cavity 511, forming a locked state, so that the drive disc 52 and the cleaning head housing 51 rotate synchronously. When the screw rod 30 rotates in the opposite direction (rotation direction during the reset process), the ball bearing 53 moves towards the wide end of the dovetail notch 521, forming a gap with the inner wall of the assembly cavity 511. The drive disc 52 only rotates with the screw rod 30, while the cleaning head housing 51 maintains its original rotation direction or stops due to inertia, realizing unidirectional drive.

[0046] In this embodiment, the number of dovetail notches 521 and ball bearings 53 are three (or more) and they are evenly distributed circumferentially, which can make the driving torque evenly transmitted to the cleaning head housing 51, avoiding housing deformation or transmission jamming caused by excessive local force.

[0047] In this embodiment, the center of the cleaning head housing 51 is recessed upward to form an assembly cavity 511. The assembly cavity 511 extends upward, shifting the installation space of the one-way driver upward, avoiding occupying the space below the cleaning head housing 51. This allows for the adaptation of larger cleaning heads 62, while ensuring that the contact area between the cleaning head 62 and the ground is not affected, thus improving cleaning efficiency.

[0048] In this embodiment, the outer edge of the cleaning head housing extends downward to form an outer retaining ring 512. The inner circumferential wall of the outer retaining ring 512 is fixedly provided with reinforcing ribs 513 at intervals. The reinforcing ribs 513 and the outer retaining ring 512 are completely consistent with the corresponding structure in the existing mop tray, and can be directly matched with the standard cleaning head 62 on the market. There is no need to design a special cleaning head separately, which reduces the replacement cost for users.

[0049] like Figure 2 As shown, the top end of the spiral rod 30 is provided with a first connecting part 31 that is connected to the pressing cylinder. The first connecting part 31 is a cylindrical structure. The bottom end of the spiral rod 30 is provided with a second connecting part 32 that is connected to the drive disc 52. The second connecting part 32 is a flat structure to facilitate assembly.

[0050] In this embodiment, a weight-reducing groove 105 is provided on the inner side of the outer edge of the dehydration seat body 101. There are three weight-reducing grooves 105, which are spaced apart along the circumference of the dehydration seat 10. Each weight-reducing groove 105 has a fan-shaped structure, which reduces the amount of material used without affecting the overall rigidity of the dehydration seat 10.

[0051] Example 2

[0052] like Figure 7 As shown, this utility model discloses a mop, including the mop rotating structure in embodiment 1, and also includes a handle 61 and a cleaning head 62. The cleaning head 62 is detachably snapped into the cleaning head housing 51, and the handle 61 is fixedly installed on the top of the pressing sleeve 20.

[0053] In this embodiment, the handle 61 is screwed into the pressing sleeve 20, which allows for a detachable connection between the handle 61 and the pressing sleeve 20; the cleaning head 62 adopts a snap-fit ​​structure, which allows for quick disassembly and replacement.

[0054] Example 3

[0055] like Figure 8 As shown, this utility model discloses a mop assembly, including the mop in embodiment 2, and also includes a cleaning bucket 70. The cleaning bucket 70 is provided with a spin-drying bucket 71. The top of the spin-drying bucket 71 is provided with an annular support seat 711 that cooperates with the dehydration seat 10. The annular support seat 711 is used to support the annular support seat 711.

[0056] In this embodiment, the mop assembly has a ring-shaped support seat 711 that forms a surface contact support with the outer edge of the spin-dry seat 10, ensuring that the spin-dry seat 10 does not shift during pressing; the cavity structure of the spin-dry tub 71 can collect the water spun out by the cleaning head 62, preventing wastewater from overflowing.

[0057] In this embodiment of the mop assembly, the cleaning bucket 70 only needs to be equipped with a spin-drying bucket 71 and a ring-shaped support 711, without the need for additional complex transmission mechanisms. The bucket structure of the cleaning bucket 70 is simple and easy to clean.

[0058] The technical solution of this utility model has been described in detail above with reference to specific embodiments. The specific embodiments described are used to help understand the concept of this utility model. Derivations and modifications made by those skilled in the art based on the specific embodiments of this utility model also fall within the protection scope of this utility model.
