One form is that the head assembly of the cleaning tool is rotatably connected with two winding rollers, and the two ends of the disposable wiping material are wound on the two winding rollers. Thus, through the rotation of the winding roller, the dirty wiping material is replaced with clean wiping material; and through the locking of the winding roller, the wiping material performs cleaning work.

[0044] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application is further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application and do not limit the present application.

[0045] As Figures 1-5As shown, the cleaning tool of the present application comprises a first winding roller 2, a second winding roller 3, a housing 1, an operating member 6, a linkage 7 and a wiping material. The first winding roller 2 is rotationally connected with the housing 1, and the second winding roller 3 is rotationally connected with the housing 1. The wiping material is wound around the first winding roller 2 and the second winding roller 3 respectively. The operating member 6 is axially moved along the first winding roller 2 to control the linkage 7 to unlock the second winding roller 3. In the embodiment, the axial movement of the operating member 6 along the first winding roller 2 includes but is not limited to the axial coaxial movement of the operating member 6 along the first winding roller 2, and also includes the case that the operating member 6 moves parallel to the axial direction of the first winding roller 2. The operating member 6 is rotatable to drive the first winding roller 2 to rotate, and the wiping material drives the second winding roller 3 to rotate. In the embodiment, when the user operates the operating member 6, the user first pushes the operating member 6 to move axially along the first winding roller 2 to unlock the second winding roller 3, and then rotates the operating member 6 to drive the first winding roller 2 to rotate.

[0046] The cleaning tool of the present application can control the unlocking of the second winding roller 3 and the rotation of the first winding roller 2 and the second winding roller 3 through different actions of the operating member 6. The operation process is simplified, and the use of the user is facilitated.

[0047] In the embodiment, the axial movement of the operating member 6 along the first winding roller 2 controls the linkage 7 to unlock the second winding roller 3. The "control" includes the case that the operating member 6 directly acts on the linkage 7 to unlock the second winding roller 3, for example, the abutting end 64 abuts against the inclined surface 73a to unlock the second winding roller 3. The "control" also includes the case that the operating member 6 does not act, or resets, etc., to give the linkage 7 a space for free action, for example, the reset state of the linkage 7 is to unlock the second winding roller 3, and after the elastic rebound of the operating member 6 away from the linkage 7, the linkage 7 is no longer limited by the operating member 6 and elastically rebounds to the reset state, or the linkage 7 is no longer limited by the operating member 6 and falls to the reset state under the action of gravity.

[0048] In the embodiment, the linkage 7 is rotationally connected with the housing 1. The linkage 7 has a first end portion 72 and a second end portion 73. When the second winding roller 73 is locked, the first end portion 72 acts on the second winding roller 73. The operating member 6 acts on the second end portion 73 to unlock the second winding roller 73.

[0049] The locking of the second winding roller 3 can be directly controlled by the linkage 7, and of course, the locking of the second winding roller 3 can also be completed by other locking members, and the linkage 7 controls the locking members to complete the unlocking and locking of the second winding roller. In the embodiment, the unlocking and locking of the second winding roller 3 are directly acted by the linkage 7. Specifically, in the embodiment, the operating member 6 is forced to push the second end portion 73, the second end portion 73 moves upward to drive the linkage 7 to rotate, the first end portion 72 moves away from the second winding roller 3 to make the second winding roller 3 unlocked, and the second winding roller 3 can rotate, at this time, the wiping material can be updated. After the operating member 6 stops being forced, the first end portion 72 locks the second winding roller 3 again, and the second winding roller 3 is fixed, which meets the requirement of cleaning use.

[0050] In the embodiment, the reset of the operating member 6 can be completed by elastic force, and the first elastic member 41 provides elastic force for the reset of the operating member 6. The cleaning tool further comprises the first elastic member 41. The first elastic member 41 provides the operating member 6 with the action force of rebounding and resetting in the axial direction of the first winding roller 2 after stopping being forced, and the first elastic member 41 can be selected from elastic sheets, elastic hooks and springs. Another implementation manner is that the operating member 6 is made of elastic material, such as rubber material and silica gel material. The operating member made of elastic material has elasticity itself, and generates rebound force after being compressed by force, and the operating member 6 rebounds and resets by the elastic force after stopping being forced.

[0051] Specifically, when the second end portion 73 is forced, the first end portion 72 is unlocked / locked with the second winding roller 3 under the driving of the second end portion 73; and when the second end portion 73 stops being forced, the first end portion 72 is restored to lock / unlock the second winding roller 3. The restoration of the first end portion 72 can be restored to the original position by the self-weight of the first end portion 72 falling to the unlocking / locking state of the second winding roller 3. Specifically, the first end portion 72 is located at the upper end of the second winding roller 3, and moves away from the second winding roller 3 when being forced, and falls to lock the second winding roller 3 under the self-weight when not being forced; or the first end portion 72 is located at the lower end of the second winding roller 3, and moves to the second winding roller 3 to lock the second winding roller 3 when being forced, and falls away from the second winding roller 3 to unlock the second winding roller 3 under the self-weight when not being forced. The locking or unlocking of the second winding roller 3 can also be achieved by the elastic force acting on the linkage 7. Specifically, the cleaning tool further comprises a second elastic member 42. The second elastic member 42 is connected with the linkage 7 and the shell 1, and provides the linkage 7 with the action force of locking or unlocking the second winding roller 3. In the embodiment, when the second end portion 73 is forced, the first end portion 72 is unlocked with the second winding roller 3 under the driving of the second end portion 73, and when the second end portion 73 stops being forced, the first end portion 72 is restored to lock the second winding roller 3 under the rebound driving of the second elastic member 42.

[0052] Preferably, the cleaning tool further includes a knob 5. The knob 5 is rotatably connected to the housing 1 at one end of the first roller 2, and the knob 5 and the housing 1 are circumferentially limited. An operating member 6 is disposed between the knob 5 and the housing 1.

[0053] When knob 5 is rotated under force, it pushes operating member 6 to move axially along the first winding roller 2, thereby driving linkage member 7 to rotate and unlocking the second winding roller 3; or, it drives operating member 6 to rotate, thereby driving the first winding roller 2 and the second winding roller 3 to rotate. Thus, the unlocking control of the second winding roller 3 and the rotation control of the first winding roller 2 are both simplified to the rotation of knob 5, simplifying the control design and making it more convenient for users.

[0054] Preferably, the second end 73 and / or the operating member 6 are provided with an inclined surface 73a. The operating member 6 applies force to the linkage 7, and the second end 73, under the action of the inclined surface 73a, causes the linkage 7 to rotate, thus releasing the locking of the first end 72 to the second winding roller 3. In this embodiment, as... Figures 1-4 As shown, the second end 73 has a downward-facing inclined surface 73a, and the operating member 6 has an abutting end 64 that abuts against the inclined surface 73a. The abutting end 64 moves towards the first winding roller 2, pushing the inclined surface 73a upward, thus lifting the second end 73. The abutting end 64 can be an angled surface; in this case, the connection between the abutting end 64 and the inclined surface 73a is a linear connection. Alternatively, the inclined surface is provided on the operating member 6, and the first end 72 has an angled surface; the inclined surface pushes against the angled surface to achieve the action of the operating member 6 pushing against the second end 73. More preferably, the abutting end 64 is also an inclined surface, thereby increasing the contact area between the second end 73 and the operating member 6, resulting in a more balanced force when they push against each other, and extending the interaction stroke.

[0055] On the other hand, in this embodiment, the second end 73 is located at the upper end of the operating member 6, and correspondingly, the first end 72 is located below the second winding roller 3. Of course, the second end 73 being located at the lower or upper end of the operating member 6, and the first end 72 being located above or below the second winding roller 3, are all variations within the protection scope of this invention.

[0056] Preferably, the knob 5 and / or the operating member 6 are provided with inclined surfaces. When the knob 5 is rotated, the operating member 6 is pushed away from the knob 5 by the inclined surfaces. In this embodiment, both the knob 5 and the operating member 6 are provided with inclined surfaces, thereby increasing the contact area between them, making the force more balanced when they push against each other, and extending the stroke of the interaction.

[0057] Specifically, the housing 1 is provided with an anti-rotation groove 11. The knob 5 is annular. The inner wall of the knob 5 is provided with a first protrusion 51 and a slope 52. The operating member 6 is provided with an anti-rotation protrusion 61, a second protrusion 62 and a slope 63.

[0058] In the embodiment, the anti-rotation protrusion 61 is embedded in the anti-rotation groove 11, and the operation member 6 is limited in circumferential movement. When the knob 5 rotates, the inclined surface 52 of the knob 5 pushes the inclined surface 63 of the operation member 6, and the operation member 6 moves linearly away from the knob 5 due to the limitation in circumferential movement. During the linear movement of the operation member 6 away from the knob 5, the anti-rotation protrusion 61 is separated from the anti-rotation groove 11, and the limitation in circumferential movement of the operation member 6 is released. When the knob 5 continues to rotate, the first protrusion 51 pushes the second protrusion 62, and the operation member 6 is driven to rotate. The operation member 6 is connected to the first winding roller 2, and the rotation of the operation member 6 can drive the first winding roller 2 to rotate. In other words, the operation member 6 and the first winding roller 2 are limited in rotation and circumferential movement, and the rotation of the operation member 6 can drive the first winding roller 2 to rotate, or the operation member 6 and the first winding roller 2 are connected through a gear transmission to realize the transmission of the rotating force. In the above-mentioned cases, the operation member 6 and the first winding roller 2 are limited in rotation and circumferential movement, the circumferential limiting structure of the first winding roller 2 can be arranged on the operation member 6, or the circumferential limiting structure of the operation member 6 can be arranged on the first winding roller 2, or the circumferential limiting structure of the operation member 6 and the first winding roller 2 can be arranged on the knob 5. These modifications are within the protection scope of the present application.

[0059] Preferably, the anti-rotation protrusion 61 is a gear tooth formed on the outer edge of the operation member 6, and the anti-rotation groove 11 is formed with a gear slot corresponding to the gear tooth of the outer edge of the operation member 6.

[0060] Preferably, the first winding roller 2 is arranged to rotate in one direction with respect to the housing 1. The direction of cleaning and the direction of replacing the wiping material are opposite to each other, so that the fixing and control of the first winding roller 2 can be simplified. The structure of one-way rotation includes conventional techniques in the prior art.

[0061] Preferably, a ratchet type one-way movement mechanism is arranged between the first winding roller 2 and the housing 1, and the ratchet type one-way movement mechanism includes a ratchet 21 and a first pawl 22, and the first pawl 22 rotates along the ratchet 21. When the ratchet type one-way movement mechanism acts on the first winding roller 2, the rotation of the knob 5 and the operation member 6 is also limited in one direction through the linkage of the first winding roller 2 and the knob 5, and the linkage of the operation member 6 and the knob 5.

[0062] The side wall of the housing 1 is provided with a circular hole, the ratchet 21 is arranged along the circular hole in the circumferential direction, the first pawl 22 is fixedly connected with the first winding roller 2, and the first pawl 22 is surrounded by the ratchet 21.

[0063] The first pawl 22 includes an arc-shaped sheet 22a and a disc 22b, the arc-shaped sheet 22a is fixedly arranged on the periphery of the disc 22b, the distal end of the arc-shaped sheet 22a is formed with a sharp tooth, and the disc 22b is fixedly connected with the first winding roller 2.

[0064] Preferably, the tooth grooves of the ratchet 21 correspond to the tooth grooves of the anti-rotation groove 11. Thus, when the operating member 6 rotates away from the anti-rotation groove 11, it is limited by the tooth grooves of the ratchet 21. For each rotation of the operating member 6, the next adjacent tooth remains in a state corresponding to the tooth groove of the anti-rotation groove 11. Thus, when the knob 5 stops being subjected to force, the operating member 6 springs back away from the first winding roller 2 and returns to the anti-rotation groove 11 in a fitting manner.

[0065] In another embodiment, the housing 1 is provided with a pawl elastic element 13 and a second pawl 14. The pawl elastic element 13 forces the second pawl 14 to abut against the teeth formed on the outer edge of the operating member 6. Thus, when the operating member 6 is limited by circumferential unidirectional rotation, the linkage knob 5 and the first winding roller 2 are also limited by circumferential unidirectional rotation. Preferably, the second pawl 14 has a tooth groove that matches the anti-rotation groove 11. Thus, when the operating member 6 rotates away from the anti-rotation groove 11, limited by the second pawl 14, for each tooth the operating member 6 rotates, the next adjacent tooth still maintains a state corresponding to the tooth groove of the anti-rotation groove 11. Thus, when the knob 5 stops being stressed, the operating member 6 springs back away from the first winding roller 2 and returns to the anti-rotation groove 11 in a perfectly fitting manner.

[0066] In this embodiment, the specific structure on the first end 72 side is as follows: one end of the second winding roller 3 is provided with a gear 32, and the first end 72 has a toothed surface that meshes with the gear 32. When the toothed surface meshes with the gear 32, the second winding roller 3 is locked; when the toothed surface disengages from the gear 32, the second winding roller 3 can rotate. The meshing design between the teeth is simple in structure and consistent with the overall design of this embodiment. Of course, the locking structure of the first end 72 for the second winding roller 3 can also be that the first end 72 is inserted into the second winding roller 3 as a pin to form an insertion matching mechanism; or the first end 72 forms a clamping surface to clamp the second winding roller 3 therein. These locking means commonly used by those skilled in the art are all within the protection scope of this invention.

[0067] Preferably, such as Figure 5 As shown, the end of the second winding roller 3 furthest from the linkage 7 is a round shaft 31. The housing 1 is provided with a groove 15 into which the round shaft 31 can fall, and the round shaft 31 can rotate within the groove 15. The housing 1 is also provided with an elastic block 16, and the elastic block 16 and the side wall of the round shaft 31 form a mutually abutting surface. As a passive winding roller, the second winding roller 3 will continue to rotate due to inertia at the moment the wiping material is replaced, which will cause the wiping material to loosen and become inconvenient to clean. The abutment of the round shaft 31 by the elastic block 16 effectively restricts the inertial rotation of the second winding roller 3, allowing the wiping material to remain taut after replacement.

[0068] In the embodiment, the shell 1 is provided with a hole site 17, a button 18 and a third elastic member 19. One end of the first winding roller 2 is provided with a transmission rod 23 embedded in the hole site 17 and a fourth elastic member 24. The other end of the first winding roller 2 is rotatably connected to the other side of the shell 1. The button 18 pushes the transmission rod 23. The transmission rod 23 is movably arranged along its axial direction, and the fourth elastic member 24 pushes the transmission rod 23. The button 18 is movably arranged along its axial direction, and the third elastic member 19 pushes the button 18.

[0069] When the first winding roller 2 is loaded into the shell 1, the transmission rod 23 moves towards the hole site 17, and the fourth elastic member 24 is compressed until the transmission rod 23 is embedded in the hole site 17 and then rebounds to push the button 18. The button 18 pushes the transmission rod 23 under force, and the fourth elastic member 24 is compressed until the transmission rod 23 is separated from the hole site 17, so that the first winding roller 2 can be conveniently disassembled. After the button 18 is not under force, it is reset by the third elastic member 19.

[0070] In the embodiment, the knob 5 is sleeved on the button 18, and the knob 5, the button 18, the first winding roller 2 and the operating member 6 are coaxially arranged. Thus, the loading and disassembling of the first winding roller 2, the replacement and change of the wiping material, and the fixing of the cleaning state of the cleaning tool are all performed at the same operation point, and the structure is simple and the use is convenient.

[0071] In specific operation, the knob 5 is rotated under force, and the operating member 6 is moved along the axial direction of the first winding roller 2 towards the first winding roller 2. In this process, the anti-rotation groove 11 limits the operating member 6 to prevent it from rotating, the first elastic member 41 is under force, the operating member 6 pushes the second end 73 to rotate, the first end 72 moves away from the second winding roller 3 to unlock the second winding roller 3, and the second elastic member 42 is under force. The operating member 6 moves towards the first winding roller 2 until it is separated from the anti-rotation groove 11, the knob 5 continues to rotate under force, drives the operating member 6 to rotate, and the operating member 6 drives the first winding roller 2 to rotate, and the first winding roller 2 drives the second winding roller 3 to rotate through the wiping material. Thus, the wiping material can be replaced. When the knob 5 stops under force, the first elastic member 41 rebounds and pushes the operating member 6 to move away from the first winding roller 2, the operating member 6 returns to be limited by the anti-rotation groove 11, and the second elastic member 42 rebounds and pushes the first end 72 to restore the locking of the second winding roller 3. Thus, the cleaning tool can perform cleaning work.

[0072] The above description in the specification is only an example of the present application. Those skilled in the art can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, as long as they do not deviate from the content of the present application or exceed the scope defined by the present claims, which should belong to the protection scope of the present application.
