Description

Technical Field

[0001] This invention relates to the field of flat mops, and in particular to a flat mop with a multiple-pull wringing action. Background Technology

[0002] Flat mops are a common floor cleaning tool. For example, patent number CN213787224U discloses a mop that is easy to wring out, which includes a main mop board, multiple side plates rotatably mounted on the main mop board, and cleaning components. An outer handle is connected to the main mop board, and a drive mechanism for rotating a rotating base is installed inside the outer handle. The drive mechanism includes an outer connector hinged to the main mop board and an inner handle slidably mounted inside the outer handle. A screw is sleeved inside the inner handle, and a screw sleeve cooperating with the screw is fixed to the lower end of the inner handle. An inner connector is sleeved inside the outer connector, with one end connected to the rotating base and the other end connected to the screw.

[0003] When wringing out water, pulling the inner handle causes the screw sleeve to slide upwards. The screw sleeve then rotates the screw, which in turn rotates the rotating seat via the inner connector, thus wringing out the water. This type of mop, however, uses a single pull to wring out water. The wringing process is limited by the twisted rod and cannot be adjusted according to the actual condition of the cleaning cloth. This results in incomplete wringing or difficult wringing. For example, when the cleaning cloth is wet, a single pull is insufficient; when the cleaning cloth is dry, a single pull is difficult, making it impossible to control the degree of wringing. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] The problem to be solved by the present invention is to provide a multi-pull wringing flat mop to overcome the defects of existing mops that cannot control the degree of wringing, which easily leads to incomplete wringing and laborious wringing.

[0006] (II) Technical Solution

[0007] To solve the aforementioned technical problem, the present invention provides a multi-pull wringer flat mop, comprising a mop seat and a mop handle connected to each other. A wringer seat for wringing out cleaning components is rotatably installed inside the mop seat. A drive device is installed inside the mop handle. The drive device includes a cooperating screw and a screw sleeve. The screw sleeve can slide along the screw and simultaneously drive the screw to rotate.

[0008] It also includes a clutch locking mechanism connected between the drive device and the wringer seat for continuous multiple wringing of the cleaning component; the clutch locking mechanism includes a clutch seat that can drive the wringer seat to rotate, the lower end of the screw is slidably installed in the clutch seat, the extended end of the screw is provided with a first tooth, and the clutch seat is provided with a second tooth that can mesh with the first tooth; the clutch seat is provided with a pawl, and the inner wall of the mop handle is provided with a locking part that can lock the pawl in one direction; when the screw sleeve slides upward, the first tooth engages with the second tooth to drive the wringer seat to rotate and wring water; when the screw sleeve slides downward, the first tooth disengages from the second tooth, and the locking part locks the pawl to prevent the wringer seat from rotating.

[0009] Furthermore, the clutch locking mechanism also includes a transmission seat that is driven and connected to the squeezing seat, and the clutch seat is slidably mounted on the outside of the transmission seat; one end of the transmission seat is provided with a third tooth, and the clutch seat is provided with a fourth tooth that can mesh with the third tooth; when the clutch seat slides down, the third tooth and the fourth tooth disengage, and the squeezing seat rotates back to its original position.

[0010] Furthermore, the screw sleeve is detachably connected to the upper end of the clutch seat, and the end of the screw sleeve is symmetrically provided with a first elastic buckle. The clutch seat is provided with an annular groove that can engage with the first elastic buckle. When the first elastic buckle engages with the annular groove, the screw sleeve can drive the clutch seat to slide, so that the third tooth and the fourth tooth engage or disengage.

[0011] Furthermore, the outer wall of the clutch seat is provided with an annular limiting plate, and the inner wall of the mop handle is provided with a retractable part to block the annular limiting plate; when the annular limiting plate abuts against the retractable part, the screw sleeve continues to slide upward, and the screw sleeve disengages from the clutch seat while driving the screw to rotate.

[0012] Furthermore, there are multiple pawls, which are equally spaced along the circumference on the outer wall of the clutch seat, and all the pawls are bent in the same direction of rotation; multiple blocking teeth are equally spaced in a ring at the locking part, and a vertical stop surface is provided on one side of each blocking tooth, and an inclined stop surface is provided on the other side.

[0013] Furthermore, the transmission seat is located on the lower side of the screw, and the end of the transmission seat facing the screw is provided with a receiving groove. The bottom of the receiving groove is provided with a first limiting rod, and the end of the screw is provided with a second limiting rod corresponding to the first limiting rod. When the screw sleeve slides down, it first drives the screw to slide down and abut against the first limiting rod. After the screw is limited, the screw sleeve slides along the screw to the bottom.

[0014] Furthermore, the mop handle is symmetrically provided with second elastic buckles, and the clutch seat is provided with a pushing part for pushing the second elastic buckles outward; when the pushing part is located above the second elastic buckle, the second elastic buckle is used to limit the clutch seat to keep it engaged with the transmission seat; when the pushing part is located below the second elastic buckle, the second elastic buckle is used to restrict the clutch seat from sliding within the mop handle.

[0015] Furthermore, the clutch seat includes a main body, a locking member fixed to the outer side of the upper end of the main body, and a clutch tooth fixed to the inner side of the lower end of the main body. The pawl, the annular groove, and the annular limiting plate are all disposed on the locking member. The second tooth is disposed on the main body, and the fourth tooth is disposed on the clutch tooth. A receiving space is formed between the main body and the clutch tooth, and the lower end of the screw and the upper end of the transmission seat both extend into the receiving space.

[0016] Furthermore, the mop handle includes an outer rod and an inner rod slidably installed inside the outer rod. The outer rod is hinged to the mop seat via a first connecting seat. A screw is sleeved on the bottom end of the inner rod, and the screw is located inside the inner rod. The clutch locking mechanism is installed on the bottom end of the outer rod, and the locking part is disposed on the inner wall of the outer rod.

[0017] Furthermore, the mop holder includes a main board and multiple side plates hinged to the side ends of the main board. The wringer seat is rotatably mounted in the middle of the main board, and the wringer seat is connected to the transmission seat through a second connecting seat. A torsion spring is provided at the connection between the side plate and the main board, and the torsion spring is used to reset the side plate and the wringer seat.

[0018] (III) Beneficial Effects

[0019] This invention provides a multi-pull wringing flat mop, which adds a clutch locking mechanism. Through the cooperation of the clutch seat and the transmission seat, in the wringing state, when the screw sleeve slides up, the first tooth engages with the second tooth, which drives the wringing seat to rotate and squeeze water. When the screw sleeve slides down, the first tooth disengages from the second tooth, and the locking part locks the pawl to prevent the wringing seat from rotating back. After wringing is completed, pushing the clutch seat down causes the third and fourth teeth to disengage, and the wringing seat rotates back to its original position. This flat mop replaces the single-pull wringing method with a multi-pull wringing method. The multi-pull wringing method can control the degree of wringing, and can be pulled several times according to the actual situation of the cleaning cloth. It is more flexible to use, has a better wringing effect, and is less laborious to wring. It overcomes the defects of existing mops that cannot control the degree of wringing, which easily leads to incomplete wringing and laborious wringing. Attached Figure Description

[0033] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0034] See Figures 1 to 12 The present invention provides a multi-pull wringer flat mop, including a mop base 1 and a mop handle 2 connected to each other, as well as a clutch locking mechanism 3.

[0035] See Figure 1 , Figure 2 and Figure 9 The mop holder 1 has a wringer seat 11 rotatably mounted inside for wringing out the cleaning component. The mop holder 1 includes a main board 12 and multiple side plates 13 hinged to the sides of the main board 12. There are four side plates 13, two on each side. The wringer seat 11 is rotatably mounted in the middle of the main board 12. The wringer seat 11 is connected to the transmission seat 32 via a second connecting seat 14. One end of the second connecting seat 14 is hinged to the wringer seat 11, and the other end is hinged to the transmission seat 32. The wringer seat 11 is provided with a hook plate 16, and the outer end of the side plate 13 is provided with a hook portion 17. The four corners and the middle of the cleaning component are provided with hook rings, which are hooked onto the hook plate 16 and the hook portion 17 respectively. When the wringer seat 11 rotates, it can drive the cleaning component to twist and squeeze out water, thereby causing the side plate 13 to bend. A torsion spring 15 is provided at the connection between the side plate 13 and the main board 12. The torsion spring 15 is used for the side plate 13 and the wringer seat 11 to reset.

[0036] See Figure 3 and Figure 10The mop handle 2 is equipped with a drive device, which includes a cooperating screw 21 and a screw sleeve 22. The screw sleeve 22 can slide along the screw 21 and simultaneously drive the screw 21 to rotate. The mop handle 2 includes an outer rod 23 and an inner rod 24 slidably installed inside the outer rod 23. The outer rod 23 is hinged to the mop seat 1 through a first connecting seat 25. The screw sleeve 22 is fixedly installed at the bottom end of the inner rod 24, and the screw 21 is located inside the inner rod 24. A clutch locking mechanism 3 is installed at the bottom end of the outer rod 23, and a locking part 201 is provided on the inner wall of the outer rod 23.

[0037] See Figures 3 to 8 The clutch locking mechanism 3 is connected between the drive device and the wringer seat 11 to enable continuous multiple wringing of the cleaning component. The clutch locking mechanism 3 includes a clutch seat 31 that can drive the wringer seat 11 to rotate. The lower end of the screw 21 is slidably installed in the clutch seat 31. The protruding end of the screw 21 is provided with a first tooth 211. The clutch seat 31 is provided with a second tooth 311 that can mesh with the first tooth 211. The clutch seat 31 is provided with a pawl 312. The inner wall of the outer rod 23 of the mop handle 2 is provided with a locking part 201 that can lock the pawl 312 in one direction. The pawl 312 and the locking part 201 cooperate to lock the clutch seat 31 after the first tooth 211 and the second tooth 311 are disengaged, thereby preventing the wringer seat 11 from rotating back to its original position and ensuring that multiple wringing operations can be achieved.

[0038] See Figures 3 to 9 The clutch locking mechanism 3 also includes a transmission seat 32 that is driven and connected to the squeezing seat 11. The clutch seat 31 is slidably mounted on the outside of the transmission seat 32. One end of the transmission seat 32 is provided with a third tooth 321, and the clutch seat 31 is provided with a fourth tooth 313 that can mesh with the third tooth 321. When the clutch seat 31 is pushed down, the third tooth 321 and the fourth tooth 313 disengage, and the squeezing seat 11 rotates back to its original position. Through the cooperation of the third tooth 321 and the fourth tooth 313, after squeezing is completed, the two teeth can be disengaged by pushing the clutch seat 31 down, thereby unlocking the squeezing seat 11 and allowing it to rotate back to its original position.

[0039] See Figure 4 , Figure 5 and Figure 10The upper end of the screw sleeve 22 is detachably connected to the clutch seat 31. The end of the screw sleeve 22 is symmetrically provided with a first elastic buckle 221, and the clutch seat 31 is provided with an annular groove 314 that can engage with the first elastic buckle 221. When the first elastic buckle 221 engages with the annular groove 314, the screw sleeve 22 can drive the clutch seat 31 to slide, causing the third tooth 321 and the fourth tooth 313 to engage or disengage. The use of the first elastic buckle 221 and the annular groove 314 facilitates the separation and connection of the screw sleeve 22 and the clutch seat 31 as needed during wringing. Furthermore, during mopping, the first elastic buckle 221 engaging with the annular groove 314 prevents the screw sleeve 22 and inner rod 24 from shaking, reducing collisions and noise.

[0040] See Figure 4 , Figure 5 and Figure 10 The outer wall of the clutch seat 31 is provided with an annular limiting plate 315, and the inner wall of the mop handle 2 is provided with a retractable part 206 to block the annular limiting plate 315. When the annular limiting plate 315 abuts against the retractable part 206, the screw sleeve 22 continues to slide upward, and the screw sleeve 22 disengages from the clutch seat 31 and drives the screw 21 to rotate.

[0041] See Figure 5 , Figure 6 and Figure 8 There are four pawls 312, which are evenly spaced along the circumference on the outer wall of the clutch seat 31. All pawls 312 are bent in the same direction of rotation. The pawls 312 and the locking member 318 are integral plastic parts, allowing them to undergo a certain degree of elastic deformation. Multiple blocking teeth 202 are evenly spaced in a ring at the locking part 201. One side of the blocking tooth 202 is provided with a vertical stop surface 203, and the other side is provided with an inclined stop surface 204. The inclined stop surface 204 can push the pawl 312 to undergo a certain degree of elastic deformation, thereby allowing it to rotate in one direction. The vertical stop surface 203 can restrict the pawl 312 from rotating in the other direction, thus ensuring the unidirectional rotation of the clutch seat 31.

[0042] See Figure 9 and Figure 10 The transmission seat 32 is located on the lower side of the screw 21. The end of the transmission seat 32 facing the screw 21 is provided with a receiving groove 322. The bottom of the receiving groove 322 is provided with a first limiting rod 323. The end of the screw 21 is provided with a second limiting rod 212 corresponding to the first limiting rod 323. When the screw sleeve 22 slides down, it first drives the screw 21 to slide down and abut against the first limiting rod 323. After the screw 21 is limited, the screw sleeve 22 slides along the screw 21 to the bottom.

[0043] See Figure 7 , Figure 10 and Figure 11The mop handle 2 is symmetrically provided with second elastic buckles 205, and the clutch seat 31 is provided with a pushing part 316 for pushing the second elastic buckles 205 outward. Both the upper and lower sides of the second elastic buckles 205 are provided with inclined baffles, allowing the clutch seat 31 to slide upward or downward to push the second elastic buckles 205 outward. When the pushing part 316 is located above the second elastic buckle 205, the second elastic buckle 205 limits the clutch seat 31, keeping it engaged with the transmission seat 32; when the pushing part 316 is located below the second elastic buckle 205, the second elastic buckle 205 restricts the clutch seat 31 from sliding within the mop handle 2, preventing wobbling.

[0044] See Figure 6 and Figure 7 For ease of manufacturing, the clutch seat 31 adopts a split structure. The clutch seat 31 includes a main body 317, a locking member 318 fixed on the outer side of the upper end of the main body 317, and a clutch tooth 319 fixed on the inner side of the lower end of the main body 317. The pawl 312, the annular groove 314, and the annular limiting plate 315 are all provided on the locking member 318. The second tooth 311 is provided on the main body 317, and the fourth tooth 313 is provided on the clutch tooth 319. A receiving space 320 is formed between the main body 317 and the clutch tooth 319. The lower end of the screw 21 and the upper end of the transmission seat 32 both extend into the receiving space 320.

[0045] See Figures 10 to 12 The usage process of this pull-out wringer flat mop is as follows:

[0046] See Figure 10 Under normal conditions, under the limitation of gravity and the second elastic buckle 205, the clutch seat 31 is in a low position, the third tooth 321 and the fourth tooth 313 disengage, the first limiting rod 323 abuts against the second limiting rod 212, the first tooth 211 engages with the second tooth 311, and the first elastic buckle 221 engages with the annular groove 314.

[0047] See Figure 11In the initial stage of squeezing, the outer upper side pulls the inner rod, causing the screw sleeve 22 to slide upward. The screw sleeve 22 drives the clutch seat 31 and the screw 21 to slide upward synchronously through the first elastic buckle 221 (at this time, the screw 21 and the screw sleeve 22 have no relative sliding, and the screw 21 does not rotate; the first tooth 211 and the second tooth 311 remain engaged). Then, the pushing part 316 of the clutch seat 31 pushes the second elastic buckle 205 outward and places it on the upper side of the second elastic buckle 205. At this time, the clutch seat 31 is in a high position, and the third tooth 321 and the fourth tooth 313 are engaged. The first limit rod 323 and the second limit rod are engaged. The separation of the position rod 212 creates a gap, and the second elastic buckle 205 prevents the clutch seat 31 from falling, keeping it in the meshing state of the third tooth 321 and the fourth tooth 313. At the same time, the annular limiting plate 315 abuts against the contraction part 206, and the clutch seat 31 is limited. Since the screw sleeve 22 continues to slide upward, the screw sleeve 22 separates from the clutch seat 31. At this time, the screw sleeve 22 drives the screw 21 to rotate (the screw sleeve 22 slides relative to the screw 21), the screw 21 drives the clutch seat 31 to rotate, the clutch seat 31 drives the transmission seat 32 to rotate, and the transmission seat 32 drives the squeezing seat 11 to rotate and wring water.

[0048] See Figure 12 When the screw sleeve 22 slides up to the top and then slides down, the screw sleeve 22 first drives the screw 21 to slide down (at this time, the screw 21 and the screw sleeve 22 have no relative sliding, and the screw 21 does not rotate). The first tooth 211 disengages from the second tooth 311, and the locking part 201 locks the pawl 312 to prevent the water squeezing seat 11 from rotating. When the screw 21 is stopped against the first limit rod 323, the screw sleeve 22 slides along the screw 21 to the bottom (the two slide relative to each other), and the screw 21 rotates in the opposite direction. This completes one pulling process. Since the water squeezing seat is not reset, the pulling process can be repeated several times as needed.

[0049] After the squeezing is complete, the clutch seat 31 is pushed down by the inner rod, causing the clutch seat 31 to push the second elastic buckle 205 outward and place it under the second elastic buckle 205. At this time, the clutch seat 31 is in a low position, the third tooth 321 and the fourth tooth 313 disengage, the transmission seat is unlocked, and the squeezing seat rotates back to its normal position under the action of the torsion spring.

[0050] This embodiment provides a multi-pull wringer flat mop, which adds a clutch locking mechanism. Through the cooperation of the clutch seat and the transmission seat, the single-pull wringing method is replaced with a multi-pull wringing method. The multi-pull wringing method can control the degree of wringing. It can be pulled several times according to the actual situation of the cleaning cloth, making it more flexible to use, with better wringing effect and less effort.

[0051] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
