Description

Technical Field

[0001] The utility model relates to the technical field of household cleaning daily necessities, in particular to a mop. Background Art

[0002] In order to clean the mop plate and avoid the water squeezing frame limiting the mop rod when using the mop, resulting in the mop rod being unable to be parallel to the ground, that is, the mop cannot clean the gaps under the furniture, it is usually necessary for the water squeezing frame to be 90 degrees different between the state when cleaning the mop plate and the state when in normal use.

[0003] The prior art hands-free mop can be provided with a guide pin on the mop rod and a spiral guide groove on the water squeezing frame. The guide pin can slide in the guide groove and drive the water squeezing frame to rotate 90 degrees, so that the water squeezing frame can be parallel to the width direction of the mop board when cleaning the mop board, and the water squeezing frame can be perpendicular to the width direction of the mop board when the mop is normally used, so as to facilitate mopping under objects with low height along the width direction of the mop board when mopping the floor. However, the guide pin will collide with the side wall of the guide groove every time it enters the guide groove, resulting in a large noise when the mop is used, and a poor user experience. Utility Model Content

[0004] In view of this, the utility model provides a mop to solve the problem of high noise in the use of mops in the prior art.

[0005] The utility model provides a mop, comprising:

[0006] mop handle;

[0007] A mop plate movably connected to the end of the mop rod;

[0008] A water squeezing mechanism is slidably arranged on the mop rod and is used to clean the wiping material arranged on the mop plate when sliding along the axial direction of the mop rod;

[0009] A guide groove is provided on one of the water squeezing mechanism and the mop rod, and the guide groove includes a straight slide groove extending along the axial direction of the mop rod and a spiral slide groove extending along the axial direction and circumferential direction of the mop rod at the same time; a limiting structure is provided on the other of the water squeezing mechanism and the mop rod, and the limiting structure is used to limit the displacement of the water squeezing mechanism in the axial direction and circumferential direction of the mop rod when sliding along the guide groove;

[0010] One of the limiting structure and the guide groove is provided with a rolling body, and the rolling body is used to rotate under the drive of the other limiting structure and the guide groove when the limiting structure slides along the straight slide groove of the guide groove to the spiral slide groove.

[0011] Beneficial effect: By setting a rolling body on one of the limiting structure and the guide groove, the rolling body can rotate under the drive of the other of the limiting structure and the guide groove when the limiting structure enters the spiral groove from the straight groove, so that it can play a certain buffering role when the limiting structure collides with the guide groove, greatly reducing the collision stress and noise, and improving the service life of the mop, effectively solving the problem of collision between the existing mop guide pin and the side wall of the guide groove, resulting in loud noise when the mop is in use and poor user experience.

[0012] In an optional embodiment, the limiting structure is provided with a rolling body, and the rolling body is used to rotate driven by the side wall of the spiral slide groove when the limiting structure slides from the straight slide groove of the guide groove to the spiral slide groove.

[0013] Beneficial effects: Setting the rolling body on the moving limiting structure is more convenient and the structure is simpler. It can minimize the number of rolling bodies and save costs. It can also effectively ensure that the limiting structure and the guide groove can always maintain a state of rolling contact during the movement of the limiting structure, and the buffering and noise reduction effects are better.

[0014] In an optional embodiment, the guide groove is arranged on the water squeezing mechanism, and the limiting structure is fixedly arranged on the mop rod;

[0015] When the water squeezing mechanism slides along the mop rod, the limiting structure slides along the guide groove.

[0016] Beneficial effects: the guide groove is formed on the water squeezing mechanism, the limiting structure is fixedly arranged on the mop rod, the limiting structure is limited in the guide groove, and when the water squeezing mechanism and the mop rod slide relative to each other, the limiting structure can move along the guide track of the guide groove, that is, it can slide along the straight slide groove and the spiral slide groove of the guide groove, thereby driving the water squeezing mechanism to rotate to the avoidance position when sliding along the axial direction of the mop rod, so as to facilitate the cleaning of low gaps.

[0017] In an optional embodiment, the limiting structure includes a pin fixed on the mop rod, an end of the pin protrudes from the outer side wall of the mop rod, and the rolling body is rotatably arranged on the end of the pin.

[0018] Beneficial effects: The limiting structure adopts a pin, which has a simple structure and is convenient to assemble with the mop rod; the design that the end of the pin protrudes from the outer wall of the mop rod can ensure that the pin can extend into the guide groove, and the guide wheel is rotatably arranged on the mop rod through the pin. When the guide wheel enters the spiral groove from the straight groove, it can rotate around the pin when it is hit or subjected to other external forces, thereby providing a little buffer for the stress of the collision, avoiding a hard collision between the guide wheel and the side wall of the spiral groove, which is easy to cause structural damage and a large noise problem.

[0019] In an optional embodiment, the pin includes a pin body and a pin cap fixedly disposed at one end of the pin body;

[0020] The rolling body is rotatably sleeved and limited on the pin cap.

[0021] Beneficial effect: By rotatably sleeved the rolling body on the pin cap, on the one hand, the problem of the pin cap being exposed, unsightly and easily interfering with other parts can be avoided; on the other hand, the pin cap can be used to limit the rolling body, thereby preventing the rolling body from detaching from the pin.

[0022] In an optional embodiment, the rolling body is a guide wheel, and a stepped accommodating groove which can accommodate the pin cap and cooperate with the pin cap to limit the position is provided in the guide wheel.

[0023] Beneficial effect: The rolling body adopts the structural design of the guide wheel, which is not only simple in structure and easy and quick to assemble, but also has a stepped accommodating groove inside the guide wheel. The stepped accommodating groove can not only accommodate the pin cap to prevent the pin cap from being exposed, but also form a limit between the pin cap and the pin cap, which can effectively prevent the guide wheel from falling off.

[0024] In an optional embodiment, a stepped through hole is opened in the guide wheel, and the stepped through hole includes a first aperture section and a second aperture section, and the aperture of the first aperture section is smaller than the aperture of the second aperture section;

The outer diameter of the pin cap is between the aperture of the first aperture segment and the aperture of the second aperture segment, so that the stepped surface between the pin cap and the first aperture segment and the second aperture segment can form a limit, so that the guide wheel is limited between the pin cap and the mop rod, which can effectively avoid the problem of the guide wheel falling off easily.

[0027] In an optional embodiment, the rolling body includes any one of a ball, a guide wheel, and a roller.

[0028] Beneficial effects: The rolling body adopts the structural form of balls, guide wheels and rollers, which has a simple structure and flexible rotation, and can make the limiting structure and the guide groove form rolling contact, which can effectively avoid the problems of direct hard contact between the limiting structure and the guide groove, large damping, collision stress and noise.

[0029] In an optional embodiment, the mop further comprises:

[0030] The shock-absorbing sleeve is sleeved on the mop rod. A through hole is arranged on the shock-absorbing sleeve. The limiting structure passes through the through hole and slides with the guide groove. The shock-absorbing sleeve is used to generate elastic deformation when colliding with the water squeezing mechanism.

[0031] Beneficial effect: by means of a shock-absorbing sleeve sleeved on the mop rod, and a limiting structure passing through the through hole on the shock-absorbing sleeve and slidingly cooperating with the guide groove, the two ends of the shock-absorbing sleeve are respectively located on both sides of the limiting structure, thereby being able to protect the limiting structure; when the limiting structure slides relative to the guide groove to the upper and lower ends of the water squeezing mechanism, the shock-absorbing sleeve can generate elastic deformation when colliding with the water squeezing mechanism, thereby effectively reducing the stress of the limiting structure when colliding with the water squeezing mechanism from top to bottom, and further reducing the noise of the entire mop when in use.

[0032] In an optional implementation, there is an avoidance gap between the through hole and the limiting structure.

[0033] Beneficial effect: By setting an avoidance gap between the through hole and the limiting structure, it is possible to effectively avoid the through hole of the shock-absorbing sleeve and the guide wheel being too close or in contact, which would interfere with the normal rotation of the guide wheel and thus affect the noise reduction effect.

[0055] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0056] Combine the following Figures 1 to 11 , describing an embodiment of the utility model.

[0057] The utility model provides a mop, comprising: a mop rod 10, a mop plate 20, and a water squeezing mechanism 30, wherein the mop plate 20 is movably connected to the end of the mop rod 10; the water squeezing mechanism 30 is slidably arranged on the mop rod 10, and is used to clean the wiping material arranged on the mop plate 20 when sliding along the axial direction of the mop rod 10; a guide groove 301 is arranged on one of the water squeezing mechanism 30 and the mop rod 10, and the guide groove 301 includes a straight slide groove 3011 extending along the axial direction of the mop rod 10 and a straight slide groove 3011 extending along the axial direction and the circumferential direction of the mop rod 10 at the same time An extended spiral slide groove 3012; a limiting structure 11 is provided on the other of the water squeezing mechanism 30 and the mop rod 10, and the limiting structure 11 is used to limit the axial and circumferential displacement of the water squeezing mechanism 30 on the mop rod 10 when sliding along the guide groove 301; one of the limiting structure 11 and the guide groove 301 is provided with a rolling body, and the rolling body is used to rotate under the drive of the other of the limiting structure 11 and the guide groove 301 when the limiting structure 11 slides along the straight slide groove 3011 of the guide groove 301 to the spiral slide groove 3012.

[0058] In the above embodiment, by setting a rolling body on one of the limiting structure 11 and the guide groove 301, the rolling body can rotate under the drive of the other of the limiting structure 11 and the guide groove 301 when the limiting structure 11 enters the spiral groove 3012 from the straight groove 3011, so that it can play a certain buffering role when the limiting structure 11 collides with the guide groove 301, greatly reducing the collision stress and noise, and improving the service life of the mop, effectively solving the problem that the existing mop guide pin collides with the side wall of the guide groove 301, resulting in loud noise when the mop is in use and poor user experience.

[0059] Specifically, in this embodiment, the mop plate 20 is hinged on one end of the mop rod 10, and a wiping object is arranged on the mop plate 20. The water squeezing mechanism 30 is slidably sleeved on the mop rod 10, and the water squeezing mechanism 30 is provided with a stroking opening 300 for the mop plate 20 to pass through, and the stroking opening 300 is used to squeeze and clean the wiping object on the mop plate 20. Under the guidance of the spiral slide groove 3012 and the limiting structure 11, when the water squeezing mechanism 30 slides along the axial direction of the mop rod 10, the water squeezing mechanism 30 can also be driven to rotate along the circumferential direction of the mop rod 10, so that the water squeezing mechanism 30 can be rotated to the position where the groove 300 corresponds to the mop board 20, that is, the groove 300 is parallel to the width direction of the mop board 20, so that the water squeezing mechanism 30 can clean the mop board 20 after the mop board 20 is inserted into the groove 300; and the water squeezing mechanism 30 rotates to a position avoiding the ground, that is, the water squeezing mechanism 30 rotates 90 degrees along the circumferential direction of the mop rod 10 relative to the above position, so that the mop board can clean the gap under the furniture.

[0060] Furthermore, the limiting structure 11 cooperates with the guide groove 301 and can move along the guide track of the guide groove 301. The limiting structure 11 can adopt structural forms such as a limiting rod, a limiting pin, a limiting block, a limiting plate, etc. This embodiment does not limit the specific structure of the limiting structure 11, as long as it can ensure that it can slide along the guide groove 301.

[0061] Furthermore, the rolling body can be arranged on the limiting structure 11, or can also be arranged in the guide groove 301, and the rolling body can be any one of a ball, a guide wheel 112, and a roller. The rolling body adopts the structural form of a ball, a guide wheel 112, and a roller, which has a simple structure and flexible rotation, and can make the limiting structure 11 and the guide groove 301 form rolling contact, which can effectively avoid the problem of direct hard contact between the limiting structure 11 and the guide groove 301, large damping, collision stress and noise.

[0062] Exemplarily, when the rolling body is arranged on the limiting structure 11, it can adopt a structural form such as a ball or a guide wheel 112; when the rolling body is arranged on the guide groove 301, it can adopt a structural form such as a roller. Specifically, a plurality of rollers are arranged on the guide path of the guide groove 301. For example, a plurality of rollers can be arranged on the side wall of the junction area of ​​the straight slide groove 3011 and the spiral slide groove 3012, and the rotating axes of the plurality of rollers are arranged along the depth direction of the guide groove 301.

[0063] Preferably, when the rolling body is a ball, the ball is a universal ball, which is more flexible in movement, and the rolling body is arranged on the limiting structure 11.

[0064] In some embodiments, the limiting structure 11 is provided with a rolling body, and the rolling body is used to rotate driven by the side wall of the spiral groove 3012 when the limiting structure 11 slides from the straight groove 3011 of the guide groove 301 to the spiral groove 3012.

[0065] In the above embodiment, the rolling body is arranged on the limiting structure 11, which is more convenient and the structure is simpler. The number of rolling bodies arranged can be minimized to save costs, and the limiting structure 11 can be effectively ensured to maintain a rolling contact state at all times during the movement of the guide groove 301, thereby achieving better buffering and noise reduction effects.

[0066] In some embodiments, the guide groove 301 is disposed on the water squeezing mechanism 30 , and the limiting structure 11 is fixedly disposed on the mop rod 10 ; when the water squeezing mechanism 30 slides along the mop rod 10 , the limiting structure 11 slides along the guide groove 301 .

[0067] In the above embodiment, the guide groove 301 is formed on the water squeezing mechanism 30, and the limiting structure 11 is fixedly arranged on the mop rod 10. The limiting structure 11 is limited in the guide groove 301, and when the water squeezing mechanism 30 and the mop rod 10 slide relative to each other, the limiting structure 11 can move along the guide track of the guide groove 301, that is, it can slide along the straight slide groove 3011 and the spiral slide groove 3012 of the guide groove 301, so as to realize driving the water squeezing mechanism 30 to rotate to the avoidance position when sliding along the axial direction of the mop rod 10, so as to facilitate cleaning of low gaps.

[0068] Specifically, the limiting structure 11 protrudes from the outer peripheral wall of the mop rod 10 so that it can extend into the guide groove 301 and slide in the guide groove 301. The water squeezing mechanism 30 includes a water squeezing frame 31 and a gripping portion 32. The water squeezing frame 31 is fixedly arranged at one end of the gripping portion 32 close to the mop plate 20. The water squeezing frame 31 and the gripping portion 32 are slidably connected to the mop rod 10. A rubbing mouth 300 is formed in the water squeezing frame 31. A wiper 311 is provided on the side of the water squeezing frame 31 facing the wiped object. The wiper 311 can be in the form of a scraper, a wiper roller, or the like.

[0069] Optionally, the guide groove 301 may also be provided on the mop rod 10 , and the limiting structure 11 is provided on the water squeezing mechanism 30 and protrudes from the inner wall of the water squeezing mechanism 30 ; when the water squeezing mechanism 30 slides along the mop rod 10 , the limiting structure 11 slides along the guide groove 301 .

[0070] Furthermore, the spiral slide groove 3012 of the guide groove 301 is arranged at one end of the water squeezing mechanism 30 close to the mop plate 20, and the straight slide groove 3011 is arranged at one end of the spiral slide groove 3012 away from the mop plate 20, and the spiral slide groove 3012 and the straight slide groove 3011 are connected.

[0071] The mop has a mopping state and a squeezing state, and the positions of the squeezing mechanism 30 in the two states differ by 90 degrees along the circumference of the mop rod 10. Specifically, when the mop is in the mopping state, the mop plate 20 rotates to a position perpendicular to the mop rod 10, and the wiping material of the mop plate 20 abuts against the ground. The user can drive the mop plate 20 to clean the ground by holding the mop rod 10 and moving it back and forth. If it is necessary to clean the gap under the furniture, the mop rod 10 can be moved close to one long side of the mop plate 20 and pressed down to be basically parallel to the ground. At this time, the stroking mouth 300 of the squeezing mechanism 30 is located above the mop rod 10, and the squeezing mechanism 30 will not cause obstacles to the downward pressing of the mop rod 10, so that the mop can extend into the gap under the furniture for cleaning. When the mop plate 20 needs to be cleaned, the mop rod 10 can be rotated again to a position perpendicular to the mop plate 20, and then the mop plate 20 is rotated so that the mop plate 20 is roughly parallel to the mop rod 10. At this time, the width direction of the groove 300 of the water squeezing mechanism 30 is perpendicular to the width direction of the mop plate 20, and the mop plate 20 cannot be directly inserted into the groove 300. Then the user pushes the water squeezing mechanism 30 to move along the axial direction of the mop rod 10 toward the mop plate 20. At this time, the limiting structure 11 slides along the spiral slide 3012, driving the water squeezing mechanism 30 to rotate along the circumference of the mop rod 10 at the same time, until it rotates to the width direction of the groove 300 is parallel to the width direction of the mop plate 20. At this time, the limiting structure 11 enters the straight slide 3011 from the spiral slide 3012, and the mop is in a water squeezing state. When the limiting structure 11 enters the straight groove 3011 from the spiral groove 3012, the rolling body arranged on the limiting structure 11 can also rotate under the drive of the sharp angle of the transition between the spiral groove 3012 and the straight groove 3011, so as to reduce the friction force when the limiting structure 11 enters the straight groove 3011 from the spiral groove 3012. The user continues to apply force to push the squeezing mechanism 30, and the mop plate 20 can be inserted into the stroking mouth 300. Then the user drives the squeezing mechanism 30 to reciprocate along the axial direction of the mop rod 10, and the limiting structure 11 slides reciprocatingly along the straight groove 3011, so that the wiper 311 arranged in the stroking mouth 300 reciprocates and / or squeezes the wiped material on the mop plate 20 to clean the wiped material. After the wiping object is cleaned, when the user needs to use the mop again, the water squeezing mechanism 30 can be pushed to move along the axial direction of the mop rod 10 away from the mop plate 20 until the mop plate 20 is separated from the stroke 300. At this time, the user continues to push the water squeezing mechanism 30, and the limiting structure 11 enters the spiral groove 3012 from the straight groove 3011. During this process, the rolling body arranged on the limiting structure 11 can rotate under the drive of the side wall of the spiral groove 3012 to reduce the noise caused by the collision between the limiting structure 11 and the side wall of the spiral groove 3012.The squeezing mechanism 30 is continuously driven to move along the axial direction of the mop rod 10, and the limiting structure 11 slides along the spiral slide groove 3012, thereby driving the squeezing mechanism 30 to rotate until the squeezing mechanism 30 is rotated to a position where it clears the ground, and the mop is restored to the use state again.

[0072] In some embodiments, the limiting structure 11 includes a pin 111 fixed on the mop rod 10 , an end of the pin 111 protrudes from the outer wall of the mop rod 10 , and a rolling body is rotatably disposed on the end of the pin 111 .

[0073] In the above embodiment, the limiting structure 11 adopts the pin 111, which has a simple structure and is convenient to assemble with the mop rod 10; the design that the end of the pin 111 protrudes from the outer wall of the mop rod 10 can ensure that the pin 111 can extend into the guide groove 301, and the guide wheel 112 is rotatably arranged on the mop rod 10 through the pin 111. When the guide wheel 112 enters the spiral groove 3012 from the straight groove 3011, when it is hit or other external forces, the guide wheel 112 can rotate around the pin 111, thereby providing a little buffer for the stress of the collision, avoiding the guide wheel 112 from hard collision with the side wall of the spiral groove 3012, which is easy to cause structural damage and loud noise.

[0074] Specifically, the pin 111 penetrates the mop rod 10 in a radial direction and is fixed on the mop rod 10 , and the rolling body is rotatably sleeved on the pin 111 .

[0075] In some embodiments, the pin 111 includes a pin body 1111 and a pin cap 1112 fixedly disposed at one end of the pin body 1111 ; the rolling body is rotatably mounted and limited on the pin cap 1112 .

[0076] In the above embodiment, by rotatably sleeved the rolling body on the pin cap 1112, on the one hand, the problem of the pin cap 1112 being exposed, unsightly and easily interfering with other components can be avoided; on the other hand, the pin cap 1112 can be used to limit the rolling body, thereby preventing the rolling body from detaching from the pin 111.

[0077] In some embodiments, the rolling body is a guide wheel 112 , and a stepped receiving groove 1120 is provided in the guide wheel 112 for receiving the pin cap 1112 and for limiting the position of the pin cap 1112 .

[0078] In the above embodiment, the rolling body adopts the structural design of the guide wheel 112, which is not only simple in structure and quick and easy to assemble, but also a stepped accommodating groove 1120 is provided in the guide wheel 112. The stepped accommodating groove 1120 can not only accommodate the pin cap 1112 to prevent the pin cap 1112 from being exposed, but also form a limit between the pin cap 1112, which can effectively prevent the guide wheel 112 from falling off.

[0079] In some embodiments, a stepped through hole 1121 is opened in the guide wheel 112, and the stepped through hole 1121 includes a first aperture section and a second aperture section, and the aperture of the first aperture section is smaller than the aperture of the second aperture section; the outer diameter of the pin body 1111 is smaller than the aperture of the first aperture section, and the outer diameter of the pin cap 1112 is between the aperture of the first aperture section and the aperture of the second aperture section.

[0080] In the above embodiment, the pin 111 passes through the stepped through hole 1121 of the guide wheel 112, and the outer diameter of the pin body 1111 is smaller than the aperture of the first aperture segment, which can ensure that the guide wheel 112 can rotate freely relative to the pin 111. The outer diameter of the pin cap 1112 is between the aperture of the first aperture segment and the aperture of the second aperture segment, so that the stepped surface between the pin cap 1112 and the first aperture segment and the second aperture segment can form a limit, so that the guide wheel 112 is limited between the pin cap 1112 and the mop rod 10, which can effectively avoid the problem of the guide wheel 112 falling off easily.

[0081] Furthermore, the first aperture section is located between the second aperture section and the mop rod 10, and the inner circumference of the second aperture section and the stepped surface between the first aperture section and the second aperture section enclose a stepped accommodating groove 1120. The hole depth of the second aperture section is greater than the thickness of the pin cap 1112, so that the pin cap 1112 can be completely hidden in the stepped accommodating groove 1120, which not only improves the aesthetics, but also avoids the problem of the pin cap 1112 being exposed and easily interfering with other components.

[0082] It should be noted that the limiting structure 11 can slide along the spiral chute 3012 and enter the straight chute 3011. Similarly, it can also slide along the straight chute 3011 and enter the spiral chute 3012. However, when the existing limiting structure 11 enters the spiral chute 3012 from the straight chute 3011, it will hit the side wall of the spiral chute 3012 to generate noise. In this embodiment, the limiting structure 11 is designed with a pin 111 and a guide wheel 112. The guide wheel 112 is rotatably arranged on the mop rod 10 through the pin 111, that is, the guide wheel 112 can rotate around the pin 111 when subjected to external force. When the pin 111 enters the spiral groove 3012 from the straight groove 3011, the outer periphery of the guide wheel 112 will come into contact with the side wall of the spiral groove 3012. At this time, the guide wheel 112 will rotate around the pin 111, providing a little buffer for the stress of the collision, avoiding a hard collision between the guide wheel 112 and the side wall of the spiral groove 3012, and avoiding the problem of loud noise.

[0083] In some embodiments, the mop further includes a shock-absorbing sleeve 12, which is sleeved on the mop rod 10. A through hole 120 is provided on the shock-absorbing sleeve 12, and the limiting structure 11 passes through the through hole 120 and slides with the guide groove 301; the shock-absorbing sleeve 12 is used to generate elastic deformation when colliding with the water squeezing mechanism 30.

[0084] In the above embodiment, the shock-absorbing sleeve 12 is sleeved on the mop rod 10, and the limiting structure 11 passes through the through hole 120 on the shock-absorbing sleeve 12 and slides with the guide groove 301. The two ends of the shock-absorbing sleeve 12 are respectively located on both sides of the limiting structure 11, so that the limiting structure 11 can be protected. When the limiting structure 11 slides relative to the guide groove 301 to the upper and lower ends of the water squeezing mechanism 30, the shock-absorbing sleeve 12 can generate elastic deformation when colliding with the water squeezing mechanism 30, thereby effectively reducing the stress of the limiting structure 11 when colliding with the water squeezing mechanism 30, and further reducing the noise of the entire mop when in use.

[0085] In some embodiments, a plurality of buffer teeth 121 are respectively disposed at both ends of the shock absorbing sleeve 12. The plurality of buffer teeth 121 make it easier for the shock absorbing sleeve 12 to generate elastic deformation when it contacts and collides with the water squeezing mechanism 30.

[0086] Furthermore, a plurality of inclined grooves are respectively formed on the circumferential edges of both ends of the shock-absorbing sleeve 12 , and buffer teeth 121 are formed between two adjacent inclined grooves.

[0087] Optionally, in this embodiment, the shock absorbing sleeve 12 is made of plastic.

[0088] In some embodiments, there is an avoidance gap between the through hole 120 and the limiting structure 11 .

[0089] In the above embodiment, by setting an avoidance gap between the through hole 120 and the limiting structure 11, it is possible to effectively avoid the through hole 120 of the shock-absorbing sleeve 12 being too close to or in contact with the guide wheel 112, which would interfere with the normal rotation of the guide wheel 112 and affect the noise reduction effect.

[0090] In some embodiments, the shock-absorbing sleeve 12 as a whole has a certain elasticity and is directly clamped and fixed on the mop rod 10 .

[0091] Exemplarily, the shock absorbing sleeve 12 may adopt a C-shaped or cylindrical structure, or the shock absorbing sleeve 12 may be configured as a rolled body, and the shock absorbing sleeve 12 is sleeved and clamped on the mop rod 10 to achieve connection and fixation with the mop rod 10 .

[0092] Optionally, in this embodiment, the shock-absorbing sleeve 12 adopts a cylindrical structure, and a deformation seam is axially provided on one side of the cylindrical shock-absorbing sleeve 12. The deformation seam has a contracted state and an expanded state. When the deformation seam is in the expanded state, the shock-absorbing sleeve 12 can be assembled. When the shock-absorbing sleeve 12 is sleeved on the mop rod 10, the deformation seam can be contracted to a contracted state, thereby being tightly clamped on the mop rod 10 for fixation.

[0093] Furthermore, two through holes 120 are provided on opposite sides of the shock-absorbing sleeve 12, and the two through holes 120 are respectively used to avoid the end of the pin 111 and the guide wheel 112. The pin 111 passes through the mop rod 10 and the shock-absorbing sleeve 12 in sequence along the radial direction of the mop rod 10. Optionally, the shock-absorbing sleeve 12 can be fixed on the mop rod 10 through the pin 111.

[0094] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
