Description

Technical Field

[0001] The utility model relates to the technical field of flat mops, in particular to a cloth-clamped mop. Background Art

[0002] A flat mop is a relatively cheap traditional household cleaning mop. A cloth mop is a type of flat mop. The wiping cloth is detachably mounted on the mop head. Usually, the wiping cloth can be set in the form of disposable non-woven fabric and can be replaced at any time. The cloth mop currently in use on the market can be taken as an example of the Chinese utility model with application number "202321208085.3", which discloses a cloth mop that is convenient for replacing mops. The cloth mop includes a mop rod and a mop base plate connected to one end of the mop rod; the mop base plate is provided with a clamping assembly for clamping the mop; the clamping assembly includes a first clamping member fixed to an end of the mop base plate away from the mop rod, and a second clamping member movably connected to the mop base plate and capable of approaching or moving away from the first clamping member; wherein, a driving assembly for driving the second clamping member to approach or move away from the first clamping member is also provided on the mop base plate; and the mop rod is connected to the driving assembly, and the mop rod is pulled up or pressed down to control the driving assembly to drive the second clamping member to move toward or away from the first clamping member. Combined with the drawings in the specification, it is not difficult to find that after the two clamping parts clamp the mop, a considerable part of the mop head of the cloth-clamped mop is not clamped to the mop, and the clamped mop cloth is usually made of very thin materials such as non-woven fabrics and paper towels, so that the mop cloth can be deformed and clamped when clamped. In the case of very thin mop cloth, the exposed edges will inevitably touch the bottom parts of the clamping parts on both sides when mopping the floor, making knocking noises and causing certain wear and tear that affects the appearance and use effect; and if the clamping parts of the two clamping parts are made very thin, certain deformation may occur, resulting in poor gripping effect, and the mop may not be clamped in place or fail to be clamped. Therefore, these traditional cloth-clamped mops on the market cannot design the outer sides of the two clamping parts to be narrow edges to avoid knocking and wear problems. Utility Model Content

[0003] 1. Technical issues to be resolved

[0004] The problem to be solved by the utility model is to provide a cloth-clamped mop to overcome the defects in the prior art.

[0005] (II) Technical solution

[0006] In order to solve the technical problem, the utility model provides a cloth-clamping mop, comprising a hand-held part and a mop head, wherein the mop head comprises a bottom plate and cloth-clamping plates which can be extended or retracted relative to the bottom plate on both sides, wherein the cloth-clamping plates have an extended extended state and an inwardly retracted cloth-clamping state; the hand-held part comprises a gripping part and a driving part, and the relative movement of the gripping part and the driving part enables a transmission mechanism to drive the cloth-clamping plates to enter the extended state or the cloth-clamping state;

[0007] The outer side of the cloth clamping plate is provided with an elongated narrow edge on the side facing the bottom surface, and the narrow edge is extended along the length direction of the mop head, and the narrow edge is formed with cloth clamping claws for clamping the wiping cloth on the bottom plate; the bottom plate is formed with a wiping surface in contact with the wiping cloth on the side facing the bottom surface, and when the cloth clamping plate is in the expanded state, the lower edge of the narrow edge is lower than the clamping edges on both sides of the bottom plate.

[0008] In this solution, the wiping cloth is a disposable non-woven fabric, and a slender narrow edge is provided on the outer side of the cloth clamping plate. The width of the narrow edge is much smaller than the width of the entire mop head. The bottom surface of the base plate is basically completely wrapped by the wiping cloth, and it is not easy to bump into the two sides of the mop head during mopping with the cloth mop (there will be no sound of the plastic of the mop head bumping against the ground, and the width of the narrow edge is small, so even if there is a little bump and wear, it will not affect the overall aesthetics); the cloth clamping plate is a plastic part, and the extremely narrow edge may be deformed to a certain extent in the cloth clamping state. In order to avoid the situation where the narrow edge of the cloth clamping plate fails to clamp the wiping cloth smoothly, this solution sets the lower edge of the narrow edge to be lower than the clamping edge of the base plate when the cloth clamping plate is in the unfolded state, to ensure that the cloth clamping plate can contact the wiping cloth and clamp it to the outer end of the base plate through the cloth clamping claws.

[0009] In some embodiments, the cloth clamping claws are extended inwardly along the moving direction of the cloth clamping plate, and the outer side of the bottom plate is correspondingly provided with bottom plate clamping claws; in the cloth clamping state, the cloth clamping claws clamp the wiping cloth to the bottom plate clamping claws.

[0010] In this solution, the cloth clamping claws cooperate with the bottom plate clamping claws to firmly clamp the wiping cloth to the bottom plate; the cloth clamping claws and the bottom plate clamping claws can preferably be configured to be serrated.

[0011] In some embodiments, both sides of the mop head are provided with slide grooves for the cloth clamping plate to extend and slide, and a plurality of oblique guide plates are provided on the side of the slide groove away from the bottom plate; when the cloth clamping plate switches from the cloth clamping state to the unfolded state, the oblique guide plates guide the cloth clamping plate so that the narrow edge is always in a trend of moving toward the bottom surface, so that the lower edge of the narrow edge is lower than the clamping edges on both sides of the bottom plate; and / or,

[0012] A plurality of avoidance grooves are correspondingly arranged on the upper end surface of the cloth clamping plate; in the cloth clamping state, the oblique guide plate is placed in the avoidance grooves.

[0013] In this solution, the oblique guide plate is used to relatively push the cloth clamping plate so that the lower edge of its narrow edge can be lower than the clamping edges on both sides of the bottom plate in the expanded state; when the cloth clamping plate returns to the cloth clamping state, the avoidance groove can prevent the cloth clamping plate from being affected by the downward pressure of the oblique guide plate.

[0014] In some embodiments, a cloth clamping tooth is formed on the side of the narrow edge facing the bottom surface, and the arrangement direction of the cloth clamping tooth is perpendicular to the sliding direction of the cloth clamping plate; and / or, in the unfolded state, the lower edge of the cloth clamping tooth is lower than the lower edge of the wiping surface.

[0015] In this solution, on the basis of the cloth clamping claws, cloth clamping teeth are arranged at the bottom of the narrow edge to further improve the effect of grabbing the wiping cloth.

[0016] In some embodiments, the holding portion is an inner rod of the mop, and the driving portion is an outer rod. The inner rod and the outer rod are movably connected, and the cloth clamping plate is driven to enter the expanded state or the cloth clamping state through the relative up and down movement of the inner rod and the outer rod via the transmission mechanism; when in use, the inner rod of the mop is pulled upward relative to the outer rod, and the cloth clamping plate is driven to enter the expanded state via the transmission mechanism, the wiping cloth to be clamped is placed on the ground, the bottom plate is placed on the wiping cloth, the inner rod of the mop is pressed down, and the transmission mechanism is driven to make the cloth clamping plate enter the cloth clamping state.

[0017] In some embodiments, a rack is provided on one side of the cloth clamping plate; the transmission mechanism includes a twisted rod, a first connecting rod and a driving gear which are rotatably connected to the inner rod of the mop in sequence; the lower end of the twisted rod is placed in the outer rod, and the driving gear is meshed with the rack.

[0018] In this solution, the inner rod of the mop moves up and down relative to the outer rod, driving the twisted rod to rotate forward or reversely, thereby driving the driving gear to rotate, thereby synchronously driving the two cloth clamping plates to open outward or shrink inward to reset through the rack.

[0019] In another embodiment, an elastic member is installed on the inner side of the cloth clamping plate, and the elastic member enables the cloth clamping plate to always have a tendency to move toward the expanded state or the clamping state; the transmission mechanism includes an extrusion drive member connected to the inner rod of the mop and a pressure portion connected to the cloth clamping plate; the inner rod of the mop is pressed downward, and the extrusion drive member pushes or releases the pressure portion, so that the cloth clamping plate is retracted inwardly into the cloth clamping state; the inner rod of the mop is driven to stretch relative to the outer rod, and the extrusion drive member releases or pushes the pressure portion, so that the cloth clamping plate is expanded outwardly into the expanded state.

[0020] In some embodiments, the elastic member is a compressed spring, the transmission mechanism includes a control rod and a driving swing rod swingably installed in the mop head, the control rod is transmission-connected to the mop inner rod through a second connecting rod, and one end of the driving swing rod is transmission-connected to the cloth clamping plate;

[0021] When switching to the cloth clamping state, the mop inner rod is pressed down by hand so that the control rod presses down the driving rocker arm and swings inward, thereby driving the cloth clamping plate to be retracted inward; when switching to the unfolding state, the mop inner rod is pulled upward relative to the outer rod so that the control rod moves up and removes the downward pressure applied to the driving rocker arm, and the compressed spring pushes the cloth clamping plate to unfold outward.

[0022] In this solution, by pulling the mop inner rod upward relative to the outer rod, the pressure applied by the control rod on the driving rocker arm is cancelled, and the compressed spring causes the driving rocker arm to swing outward so that the two cloth clamping plates are stretched outward to enter the unfolded state; similarly, by pressing the mop inner rod downward relatively, the control rod presses down the driving rocker arm so that the two cloth clamping plates are retracted inward to enter the cloth clamping state; at this time, the control rod presses down the driving rocker arm to enter the self-locking state.

[0023] In some embodiments, the mop head is hingedly connected to a universal joint, the outer rod is hingedly connected to the universal joint; the universal joint is rotatably connected to the hinge seat of the mop head; and / or,

[0024] The driving rocker arm is placed in the hollow inner cavity of the hinge seat, and the driving rocker arm is hinged to the cloth clamping plate through a third connecting rod; a guide column corresponding to the driving rocker arm is arranged on the control rod, and a guide groove corresponding to the guide column is arranged on the hinge seat; a sliding groove slidably matched with the control rod is arranged on the mop head.

[0025] In this solution, two driving rocker arms are placed in the hinged seat, and the layout is reasonable; through the provided guide groove, the guide column of the control rod is placed above the driving rocker arm, and when the control rod is pressed down, the driving rocker arm can be pressed down by the guide column to retract the two cloth clamping plates.

[0026] In some embodiments, the mop head includes an upper shell, and the bottom plate is buckled on the upper shell; the bottom plate is soft plastic or foam.

[0027] In some embodiments, after the bottom plate is buckled onto the upper shell, a raised portion is formed downward in the middle of the wiping surface of the bottom plate, and the raised portion is configured to be deformed by force when the bottom plate contacts the ground for mopping, so that the wiping cloth on the bottom surface of the bottom plate fits better with the ground.

[0028] In some embodiments, the bottom plate is provided with a snap hole, the upper shell is provided with a snap-fitting portion that cooperates with the snap hole, and the upper shell is quickly mounted on the bottom plate by snapping to form a mop head. The bottom plate is provided with a wiping surface for mounting a wiping cloth on one side facing the bottom surface; the bottom plate and the upper shell are spliced ​​to form the slide groove; and / or the width of the narrow edge is less than 5 mm. By limiting the width of the narrow edge, when the wiping cloth is clamped, the entire bottom plate is basically the wiping cloth, and even when a single layer of non-woven fabric or paper towel is used as the wiping material, the narrow edge is not easily exposed.

[0029] In some embodiments, the cloth clamping plate is provided with a guide slide, and the upper shell is provided with a guide slide buckle corresponding to the guide slide; a limiting flange is provided on the guide slide, and a limiting baffle corresponding to the limiting flange is provided in the mop head; through the sliding cooperation between the guide slide and the guide slide buckle, the two cloth clamping plates can slide better in the slide groove of the mop head.

[0030] In some embodiments, the bottom plate and the upper shell are spliced ​​to form the slide groove.

[0059] Additionally, in the following description, specific details are provided to facilitate a thorough understanding of the examples. However, it will be understood by those skilled in the art that the examples can be practiced without these specific details.

[0060] The technical solutions provided by various embodiments of the present application are described below in conjunction with the accompanying drawings.

[0061] See also Figure 1 and Figure 2 , a cloth-clamping mop provided in an embodiment of the present specification comprises a hand-held portion and a mop head 2, the mop head 2 comprises a bottom plate 3 and cloth-clamping plates 4 which can be extended or retracted on both sides relative to the bottom plate 3, the cloth-clamping plates 4 are symmetrically arranged on both sides of the mop head 2; the cloth-clamping plates 4 have an extended extended state and a cloth-clamping state retracted inwardly; the hand-held portion comprises a gripping portion and a driving portion, and the relative movement of the gripping portion and the driving portion enables a transmission mechanism 6 to drive the cloth-clamping plates 4 into an extended state or a cloth-clamping state; an elongated narrow edge 5 is provided on the outer side of the cloth-clamping plates 4 facing the bottom surface, the narrow edge 5 is extended along the length direction of the mop head 2, and the narrow edge 5 is formed with cloth-clamping claws 501 for clamping the wiping cloth on the bottom plate 3, and the wiping cloth is a disposable non-woven fabric or a paper towel (not shown in the drawings); when the cloth-clamping plates 4 are in the extended state, the lower edge of the narrow edge 5 is lower than the cloth-clamping edge of the bottom plate 3 (such as Figure 4As shown, the lower edge of the narrow edge 5 is lower than the cloth edge of the outer end of the bottom plate 3 on the inner side thereof). A narrow and elongated narrow edge 5 is arranged on the outer side of the cloth plate, and the width of the narrow edge 5 is much smaller than the width of the entire mop head 2. The exposed narrow edge 5 is extremely small, so it is not easy to hit the narrow edge 5 when mopping the floor, and it is not easy to make a sound when the bottom of the mop head 2 is not wrapped by the wiping cloth and hits the ground.

[0062] In some embodiments, the bottom plate 3 is made of soft plastic or foam. Figure 3 and Figure 4 As shown, a wiping surface 301 that contacts the wiping cloth is formed on one side of the bottom surface of the base plate 3, and the middle part of the wiping surface 301 is slightly convex to form a raised portion. During mopping of the floor with the cloth mop, the wiping surface 301 is compressed to produce a certain elastic deformation, and the raised portion is deformed by force to make the wiping surface 301 fit better with the floor, ensuring that the wiping cloth on the entire wiping surface 301 can fit as much as possible with the floor to be cleaned, thereby improving the cleaning effect.

[0063] In a preferred embodiment, the width of the narrow edge 5 is less than 5 mm. By limiting the width of the narrow edge 5 and setting the narrow edge 5 to be extremely narrow, the bottom surface of the entire mop head 2 can be basically completely wrapped by the wiping cloth after the wiping cloth is clamped, and the narrow edge 5 is not easily exposed, which makes the overall appearance beautiful, and it is not easy to bump against the sides of the mop head 2 during mopping.

[0064] Among them, the cloth clamping plate 4 is a plastic part, and the extremely narrow narrow edge 5 may undergo certain deformation in the cloth clamping state. Therefore, in this embodiment, when the cloth clamping plate 4 is in the unfolded state, the lower edge of the narrow edge 5 is set to be lower than the wiping surface 301 of the bottom plate 3, ensuring that the cloth clamping plate 4 can contact the wiping cloth and clamp it to the outer end of the bottom plate 3 through the cloth clamping claws 501.

[0065] It should be pointed out that in some embodiments, in the cloth-clamped state, the lower edge of the narrow edge 5 can preferably be higher than or equal to the lower edge of the wiping surface 301, which can further ensure that the cloth-clamped mop will not bump into the narrow edge 5 during mopping, will not make knocking noises, is not prone to wear, and the overall design is reasonable and beautiful.

[0066] In some embodiments, Figure 2 and Figure 6 As shown, the cloth clamping claw 501 is extended inwardly along the moving direction of the cloth clamping plate 4, and the bottom plate clamping claw 302 is correspondingly arranged on the outer side of the bottom plate 3; in the cloth clamping state, the cloth clamping claw 501 clamps the wiping cloth to the bottom plate clamping claw 302. The cloth clamping claw 501 cooperates with the bottom plate clamping claw 302 to firmly clamp the wiping cloth to the bottom plate 3.

[0067] In one example, if Figure 2As shown, the cloth clamping claw 501 and the bottom plate clamping claw 302 are configured to be sawtooth-shaped.

[0068] In some embodiments, both sides of the mop head 2 are provided with slide grooves 201 for the cloth clamping plate 4 to extend and slide, and a plurality of oblique guide plates 202 are provided on the side of the slide groove 201 away from the bottom plate 3; when the cloth clamping plate 4 switches from the cloth clamping state to the unfolded state, the oblique guide plates 202 guide the cloth clamping plate 4 so that the narrow edge 5 is always in a trend of moving toward the bottom surface, so that the lower edge of the narrow edge 5 is lower than the lower edge of the wiping surface 301. In this embodiment, the oblique guide plates 202 relatively push the cloth clamping plate 4 so that the lower edge of its narrow edge 5 can be lower than the clamping edges on both sides of the bottom plate 3 in the unfolded state.

[0069] In some embodiments, Figure 5 , Figure 7 and Figure 8 As shown, the upper end surface of the cloth clamping plate 4 is provided with a plurality of avoidance grooves 401; in the cloth clamping state, the oblique guide plate 202 is placed in the avoidance grooves 401. Figure 8 As shown, when the cloth clamping plate 4 is restored to the cloth clamping state, the cloth clamping plate 4 can be free from the downward pressure of the oblique guide plate 202 through the avoidance groove 401.

[0070] In some preferred embodiments, Fig.11 or Fig.18 As shown, a cloth clamping tooth 502 is formed on one side of the narrow edge 5 facing the bottom surface, and the setting direction of the cloth clamping tooth 502 is perpendicular to the sliding direction of the cloth clamping plate 4. On the basis of the cloth clamping claw 501, the cloth clamping plate 4 further improves the effect of the cloth clamping plate 4 grabbing the wiping cloth by setting the cloth clamping tooth 502 at the bottom of the narrow edge 5.

[0071] like Fig.11 As shown, in one example, in the unfolded state, the lower edge of the cloth clamping teeth 502 is lower than the lower edge of the wiping surface 301 .

[0072] In some embodiments, the mop head 2 includes an upper shell 203, and the bottom plate 3 is buckled on the upper shell 203. The upper shell is quickly assembled with the bottom plate by snapping to form the mop head 2; the bottom plate 3 and the upper shell 203 are spliced ​​to form a slide groove 201.

[0073] Specifically, Figure 1 and Fig. 9 or Fig.16 As shown, a snap hole 303 is provided on the bottom plate 3, a snap-fitting portion 208 is provided on the upper shell 203, and a wiping surface 301 for installing a wiping cloth is formed on the side of the bottom surface of the bottom plate 3; after the bottom plate 3 is snapped onto the upper shell 203, a raised portion is formed downward in the middle of the wiping surface 301 of the bottom plate 3, and the raised portion is configured to be deformed by force when the bottom plate 3 contacts the ground for mopping, so that the wiping cloth on the wiping surface 301 fits better with the ground.

[0074] In some embodiments, Figure 5 , Fig.18 As shown, the cloth clamping plate 4 is provided with a guide slide plate 403, and the upper shell 203 is provided with a guide slider 207 corresponding to the guide slide plate 403. Through the sliding cooperation between the guide slide plate 403 and the guide slider 207, the two cloth clamping plates 4 can slide better in the slide groove 201 of the mop head 2.

[0075] In some embodiments, Figure 3 or Fig.12 As shown, the gripping part is the inner rod 1 of the mop, and the driving part is the outer rod 9. The inner rod 1 and the outer rod 9 are movably connected. Through the relative up and down movement of the inner rod 1 and the outer rod 9, the cloth clamping plate 4 is driven to enter the unfolded state or the cloth clamping state through the transmission mechanism 6; when in use, the inner rod 1 of the mop is pulled upward relative to the outer rod 9, and the cloth clamping plate 4 is driven to enter the unfolded state through the transmission mechanism 6, the wiping cloth to be clamped is placed on the ground, the bottom plate 3 is placed on the wiping cloth, the inner rod 1 of the mop is pressed down, and the transmission mechanism 6 is driven to make the cloth clamping plate 4 enter the cloth clamping state.

[0076] It should be pointed out that the mop head 2 can also be used as a driving unit, that is, when the mop head 2 is stepped on, the mop inner rod 1 can also be relatively lifted.

[0077] like Figure 3 or Fig.12 The mop head 2 is hingedly connected with a universal joint 8, the outer rod 9 is hingedly connected to the universal joint 8, and the universal joint 8 is rotatably connected to the hinge seat 204 of the mop head 2.

[0078] In one example, a rack 402 is provided on one side of the cloth clamping plate 4; Fig.10 As shown, the transmission mechanism 6 includes a twisted rod 601, a first connecting rod 602 and a driving gear 603 which are sequentially connected to the mop inner rod 1 in rotation; the lower end of the twisted rod 601 is placed in the outer rod 9, and the driving gear 603 is meshed with the rack 402. In this embodiment, the twisted rod 601 is driven to rotate in the positive or negative direction by the up and down movement of the mop inner rod 1 relative to the outer rod 9, thereby driving the driving gear 603 to rotate, thereby synchronously driving the two cloth clamping plates 4 to open outward or shrink inward to reset through the rack 402. In this embodiment, the mop inner rod 1 is pulled upward relative to the outer rod 9, driving the twisted rod 601 to rotate positively, driving the driving gear 603 to rotate positively through the first connecting rod 602, and driving the rack 402 to move outward, so that the two cloth clamping plates 4 are opened outward and enter the unfolded state.

[0079] In some embodiments, Figure 5 and Fig. 9As shown, a limit flange 404 is provided on the guide slide plate 403, and a limit baffle 209 for travel limit corresponding to the limit flange 404 is provided in the mop head 2. When the mop inner rod 1 drives the two cloth clamping plates 4 to expand or contract through the twisted rod and gear rack transmission, the expansion travel of the cloth clamping plates 4 is limited by the set limit flange 404 and the limit baffle 209.

[0080] In some embodiments, an elastic member is installed on the inner side of the cloth clamping plate 4, and the elastic member enables the cloth clamping plate 4 to always have a tendency to move toward the unfolded state or the clamped state; the transmission mechanism 6 includes an extrusion drive member connected to the mop inner rod 1 and a pressure portion connected to the cloth clamping plate 4, and the movement direction of the extrusion drive member is consistent with the movement direction of the mop inner rod 1; the mop inner rod 1 is pressed down, the extrusion drive member pushes or releases the pressure portion, so that the cloth clamping plate 4 is retracted inwardly into the cloth clamping state; the mop inner rod 1 is driven to stretch relative to the outer rod 9, and the extrusion drive member releases or pushes the pressure portion, so that the cloth clamping plate 4 is unfolded outwardly into the unfolded state.

[0081] When the elastic member always pushes the two cloth clamping plates 4 to expand outward, the mop inner rod 1 is pressed downward relatively, and its extrusion driving member pushes the pressed part (causing the pressed part to move inward and contract, thereby driving the cloth clamping plates 4 connected to the pressed part to contract); when the mop inner rod 1 is lifted up relatively, the two cloth clamping plates 4 can be pushed outward by the elastic member to expand to the expanded state.

[0082] When the elastic member will always pull the two cloth clamping plates 4 to retract, the mop inner rod 1 will be pressed downward relatively, and its extrusion driving member will release the pressed part (so that the extrusion driving member releases the restriction on the pressed part, and at this time, the two cloth clamping plates 4 are relatively pulled inward by the elastic member); when the mop inner rod 1 is relatively lifted up, its extrusion driving member will push the pressed part, and the cloth clamping plates 4 will be expanded outward to enter the said expanded state through the movement of the pressed part.

[0083] In one example, if Figure 12-14As shown, the elastic member is a compression spring 7, and the compression spring 7 makes the cloth clamping plate 4 have a tendency to always move toward the unfolded state; the transmission mechanism 6 includes a control rod 6001 (i.e., an extrusion drive member) and a driving swing rod 6002 (i.e., a pressure portion) swingably installed in the mop head 2, the control rod 6001 is transmission-connected to the mop inner rod 1 through a second connecting rod 6003, and one end of the driving swing rod 6002 is transmission-connected to the cloth clamping plate 4; when switching to the cloth clamping state (at this time, the bottom plate 3 is placed on the ground on the wiping cloth waiting to be clamped), the mop inner rod 1 is pressed down by hand to make the control rod 6001 press down the driving swing rod 6002 to swing inward, driving the cloth clamping plate 4 to gather inward to clamp the wiping cloth; when switching to the unfolded state, the mop inner rod 1 is pulled upward relative to the outer rod 9, so that the control rod 6001 moves up and removes the downward pressure applied to the driving swing rod 6002, and the compression spring 7 pushes the cloth clamping plate 4 to unfold outward. When the elastic member is a compression spring 7, it will always push the two cloth clamping plates 4 to expand outward. The contraction of the cloth clamping plates 4 is achieved by pressing the control rod 6001 downward to drive the rocker rod 6002 to move, and the expansion of the cloth clamping plates 4 is achieved by the thrust of the compression spring 7.

[0084] In one example, if Fig.13 As shown, the driving rocker arm 6002 and the universal joint 8 are hinged together on the hinge seat 204.

[0085] Among them, by pulling the mop inner rod 1 upward relatively, the pressure applied by the control rod 6001 on the driving rocker arm 6002 is cancelled, and the compressed spring 7 causes the driving rocker arm 6002 to swing outward so that the two cloth clamping plates 4 are stretched out to the unfolded state; similarly, by pressing the mop inner rod 1 downward relative to the outer rod 9, the control rod 6001 presses down the driving rocker arm 6002 so that the two cloth clamping plates 4 are retracted to the cloth clamping state; at this time, the control rod 6001 presses down the driving rocker arm to enter a self-locking state, and the mop inner rod 1 will always be in a state of pressing down the control rod 6001 when the cloth clamping mop is mopping the floor.

[0086] In one example, if Fig.13 As shown, the compression spring 7 is arranged directly between the two clamping plates 4 .

[0087] In some embodiments, Figure 12-14As shown, the driving swing rod 6002 is placed in the hollow inner cavity of the hinge seat 204, and the driving swing rod 6002 is hinged to the cloth clamping plate 4 through the third connecting rod 6004; the control rod 6001 is provided with a guide column 6005 corresponding to the driving swing rod 6002, and the hinge seat 204 is correspondingly provided with a guide groove 205 corresponding to the guide column 6005; the mop head 2 is provided with a sliding groove 206 that slides with the control rod 6001. Two driving swing rods 6002 are placed in the hinge seat 204, and the layout is reasonable; through the provided guide groove 205, the guide column 6005 of the control rod 6001 can enter the hinge seat 204 and be placed above the driving swing rod 6002. When the control rod 6001 is pressed down, the driving swing rod 6002 can be pressed down through the guide column 6005 to shrink and close the two cloth clamping plates 4.

Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application.
