Cloth-Clamping Flat Mop

Description

TECHNICAL FIELD

Some aspects relate to the technical field of household flat mops, and in particular to, a cloth-clamping flat mop.

BACKGROUND

A flat mop, as a common cleaning tool for families, mainly includes a mop rod and a mop head for wiping the ground. Wiping cloth is mounted at the bottom of the mop head, and the wiping cloth is usually flat. A cloth-clamping mop is one of the flat mops. In some cloth-clamping mops with a cloth-clamping function on the current market, a cloth-clamping claw and a wiping surface at the bottom of the mop head are arranged coplanarly. In an actual using process, the cloth-clamping claw clamping the wiping cloth may partially be in direct contact with the ground in the moping process to be worn, so that the aesthetic of the mop will also be affected. Taking a Chinese disclosure of a prior application of the applicant with publication No.: CN219846427U as an example, it discloses a cloth-clamping mop with conveniently replaced mop cloth. The cloth-clamping mop includes a mop rod and a mop bottom plate. The mop bottom plate is provided with a clamping assembly for clamping the mop cloth. The clamping assembly includes a first clamping member fixed to one end of the mop bottom plate away from the mop rod and a second clamping member movably connected to the mop bottom plate and capable of being close to or away from the first clamping member. In combination with specification and drawings, the bottom of the second clamping member on both sides and the bottom of the first clamping member are designed coplanarly. After the second clamping member clamps the mop cloth, the bottom of the second clamping member is exposed to the ground to be in direct contact with the ground, and the mop is worn during mopping. Therefore, it has a certain limitation in use.

In the prior art, a Chinese patent for invention with application No.: 201310227871.2 discloses a dedusting mop, including a mop rod and a mop plate connected to the mop rod. A mounting mechanism for mounting dedusting cloth or dedusting paper is arranged on one surface of the mop plate. The mounting mechanism includes a mounting groove and a clamping device connected to the mounting groove. The clamping device is of a hollow structure and the surface of the clamping device includes a plurality of clamping grooves. The clamping device is arranged on the upper end surface of the mop plate. The dedusting cloth needs to be manually detached and mounted, that is, the old dedusting cloth needs to be manually taken out from the clamping grooves. New dedusting cloth is partially put in the clamping grooves, so that the dedusting cloth is inconveniently replaced. For another example, a Chinese patent for invention with application No.: 200420082055.3 discloses a mop cloth clamping structure, including a panel connected to mop cloth. Cloth-clamping claws connected in a hinged manner and with teeth on the outer side are arranged on the panel. The hinged cloth-clamping claws also need to be manually opened to replace the mop cloth.

(III) Beneficial Effects

Compared with the prior art, the cloth-clamping flat mop provided by some aspects has the following advantages:

According to the cloth-clamping mechanisms in some aspects, the cloth-clamping claw is capable of moving relatively toward one side of the wiping surface while both sides of the mop head move outward or retract inward, so that after the wiping surface of the mop head is placed on the external wiping cloth, the cloth-clamping claw is capable of being in contact with the wiping cloth and the wiping cloth is guided by the guide plates to be finally clamped to enter the cloth-clamping receiving groove when the cloth-clamping claw of each of the cloth-clamping mechanisms clamps the cloth. The cloth-clamping receiving groove is higher than the wiping surface, so that people never mind that the cloth-clamping claw is bumped when using the mop to mop the floor in daily life.

The cloth-clamping claw in some aspects is mounted in a hinged manner on the supporting arm of each of the cloth-clamping mechanisms. Therefore, the cloth-clamping claw may turn downward to “grab” the wiping cloth. The torsional spring of the elastic member arranged at the hinge guarantees that the cloth-clamping claw is capable of clamping the wiping cloth.

The cloth-clamping claw in some aspects includes the convex tooth parts equally spaced and arranged in a staggered manner, and the convex tooth parts are eccentrically arranged to effectively grab the wiping cloth.

According to the cloth-clamping mechanism in some aspects, the supporting arm retracts inward or moves outward since the mop rod drives the driving gear shaft to rotate. In the outward move outward or inward or unfolding process, the torsional spring drives the cloth-clamping claw downward to clamp the wiping cloth, and in the inward moving process, the wiping cloth is clamped in the cloth-clamping receiving groove, so that the overall operation is convenient and reliable. The wiping cloth is conveniently replaced without contact with hands. The mop is easy to operate and the wiping cloth can be replaced in a “one-key manner”.

The technical solution provided by the embodiments of the present application will be described with reference to the accompanying drawings.

Referring to FIG. 1 and FIG. 4, in order to solve the technical problem, the specification provides a cloth-clamping flat mop, specifically including a mop rod 1, a mop head 2, and a driving mechanism. The bottom of the mop head 2 is a wiping surface 201, and wiping cloth 5 is mounted on the wiping surface 201 in a direct contact manner. Cloth-clamping mechanisms 4, capable of being opened or retracted inward to clamp cloth, are movably mounted on front and back sides of the mop head 2, and the cloth-clamping mechanisms 4 are used for clamping the wiping cloth 5. The driving mechanism drives the cloth-clamping mechanisms 4 to move outward or inward, so that the cloth-clamping mechanisms 4 are capable of being switched between an opened state and an inward-retracted cloth-clamping state. When in the opened state, the cloth-clamping mechanisms 4 are used for waiting for clamping the wiping cloth 5, and in the process that the cloth-clamping mechanisms 4 are switched from the opened state to the inward-retracted cloth-clamping state, the cloth-clamping mechanisms 4 clamp and fix the wiping cloth 5.

Each of the cloth-clamping mechanisms 4 includes a supporting arm 401 and a cloth-clamping claw 402 connected to the supporting arm 401. The cloth-clamping claw 402 is capable of moving toward one side of the wiping surface 201 (the cloth-clamping claw 402 moves toward one side of the wiping surface 201 to contact and grab the wiping cloth 5). The cloth-clamping claw 402 is configured to, in the overall outward move outward or inward process of each of the cloth-clamping mechanisms 4, enables the cloth-clamping claw 402 to move toward one side of the wiping surface 201 synchronously to draw close.

Guide plates 202 are arranged on a back side at two sides of the wiping surface 201. When each of the cloth-clamping mechanisms 4 is in an opened state, each of the cloth-clamping mechanisms 4 moves outward, the cloth-clamping claw 402 is opened outward and synchronously downward along the guide plates 202, and in this case, the cloth-clamping claw 402 is lower than the wiping surface 201. When cloth is clamped, the mop head 2 abuts against the wiping cloth 5, the driving mechanism controls each of the cloth-clamping mechanisms 4 to be switched from the opened state to an inward-retracted cloth-clamping state, and the cloth-clamping claw 402 drives the wiping cloth 5 to retracts inward to reset along the guide plates 202. Each of the guide plates 202 is configured to guide the wiping cloth 5 to enter the inward-retracted cloth-clamping state, and the inward-retracted cloth-clamping state is a state when the cloth-clamping flat mop is being used for moping and cleaning the floor normally.

In some preferred embodiments, as shown in FIG. 5 and FIG. 6, each of the guide plates 202 is an inclined guide plate for assisting the cloth-clamping claw 402 in guiding the wiping cloth 5.

In another embodiment, as shown in FIG. 17, each of the guide plates 202 may also be a thin lip guide plate. The thickness of the thin lip guide plate is proper when the thin lip guide plate does not interfere with the cloth-clamping claw 402. The thin lip guide plate is usually of a 1-3 mm thin plate structure. The thin lip guide plate protrudes out of an outer side end of the cloth-clamping claw 402 (in combination with FIG. 17, the thin lip guide plate protrudes out of the cloth-clamping claw 402 in the inward-retracted cloth-clamping state).

As shown in FIG. 4, an included angle between each of the obliquely arranged guide plates 202 and the wiping surface 201 is an acute angle.

It should be pointed out that each of the cloth-clamping mechanisms 4 is slidably mounted on one side of the mop head 2 away from the wiping surface 201 (the cloth-clamping claw 402 in the inward-retracted cloth-clamping state is higher than the wiping surface 201). In some embodiments, as shown in FIG. 4 and FIG. 5, a cloth-clamping receiving groove 3 is formed in the mop head 2, and the cloth-clamping receiving groove 3 is higher than the wiping surface 201. Each of the guide plates 202 extends to the cloth-clamping receiving groove 3, each of the cloth-clamping mechanisms 4 is slidably mounted in the cloth-clamping receiving groove 3, and the cloth-clamping claw 402 of each of the cloth-clamping mechanisms 4 in the inward-retracted cloth-clamping state retracts inward in the cloth-clamping receiving groove 3. FIG. 16 is a real object reference diagram where each of the cloth-clamping mechanisms 4 clamps the wiping cloth 5 in the cloth-clamping receiving groove 3 in the inward-retracted cloth-clamping state. In this case, each of the cloth-clamping mechanisms 4 retracts inward in the cloth-clamping receiving groove 3. The cloth-clamping claw 402 clamping the wiping cloth 5 is also placed in the cloth-clamping receiving groove 3. Each of the cloth-clamping mechanisms 4 is capable of enabling the wiping cloth 5 to completely clamp and wrap the wiping surface 201 in the front-back direction, so that the mopping effect is excellent, and a phenomenon that the cloth-clamping claw is worn as the cloth-clamping claw is exposed during mopping when the cloth-clamping claw is flush with the wiping surface in the prior art is avoided.

Each of the guide plates 202 forms a cloth-clamping path when clamping the wiping cloth 5 and guides the cloth-clamping claw 402 to clamp the wiping cloth 5 in the cloth-clamping receiving groove 3 (the outer side part of the wiping cloth 5 is turned to enter the cloth-clamping receiving groove 3). As shown in FIG. 15, it is a real object reference diagram where each of the cloth-clamping mechanisms 4 on the mop head 2 clamps the wiping cloth 5 in the cloth-clamping receiving groove 3. The wiping cloth 5 on the front and back sides is partially and automatically “put in” the cloth-clamping receiving groove 3 through each of the cloth-clamping mechanisms 4, so that a purpose of automatically clamping the wiping cloth 5 is achieved, and the wiping cloth is conveniently replaced. The wiping cloth 5 is not manually mounted on the mop head 2, and the wiping cloth 5 is prevented from being in contact with hands.

The wiping cloth 5 in the embodiment of the specification is a non-woven fabric. A real sample product of the cloth-clamping flat mop according to the above principle is good in actual mopping effect, accurate and reliable to clamp cloth, and convenient to switch cloth clamping.

In an example, the cloth-clamping claw 402 in the embodiment of the specification may be rotationally mounted on one side of the supporting arm 401 up and down by using a hinged shaft in a hinged manner, and the cloth-clamping claw 402 may turn toward one side of the wiping cloth 5 to draw close. The cloth-clamping claw 402 in the opened state is in contact with the wiping cloth 5, and when being switched from the opened state to the inward-retracted cloth-clamping state, the cloth-clamping claw 402 clamps the wiping cloth 5 in the cloth-clamping receiving groove 3.

It should be pointed out that, different from that in the prior art, the cloth-clamping claw 402 in the embodiment of the specification may not only be driven by the supporting arm 401 to move outward or inward in the cloth-clamping receiving groove 3, but also may turn and swing toward one side of the wiping surface 201 relative to the supporting arm 401, so that the cloth-clamping claw 402 is capable of abutting against the wiping cloth 5 to grab the wiping cloth 5. Furthermore, the guide plates 202 arranged on both sides form the cloth-clamping path, and the wiping cloth 5 is finally clamped and positioned in the cloth-clamping receiving groove 3, so that the operation is simple, and the wiping cloth may be replaced in a “one-key manner”. The obliquely arranged guide plates 202 are further beneficial for clamping the cloth more stably. The cloth-clamping claw 402 in the opened state is large in unfolding stroke, so that it is convenient to grab the wiping cloth 5.

When each of the cloth-clamping mechanisms 4 clamps the cloth, as shown in FIG. 14, the wiping surface 201 of the mop head 2 is placed on new wiping cloth 5, and the cloth-clamping claw 402 in the opened state (waiting for clamping the cloth) abuts against the wiping cloth 5. In the process that each of the cloth-clamping mechanisms 4 is switched from the opened state to the inward-retracted cloth-clamping state, the supporting arm 401 guides the cloth-clamping claw 402 to retract inward to reset. The cloth-clamping claw 402 correspondingly clamps the wiping cloth 5 guided by each of the guide plates 202 in the cloth-clamping receiving groove 3 finally through the plane of the wiping surface 201. As shown in FIG. 14, in this case, each of the cloth-clamping mechanisms 4 is in the inward-retracted cloth-clamping state, and the cloth-clamping claw 402 retracts inward in the cloth-clamping receiving groove 3.

In some embodiments, when each of the cloth-clamping mechanisms 4 is in the opened state, the cloth-clamping claw 402 is lower than the wiping surface 201. As shown in FIG. 14, after ensuring that the entire mop head 2 is placed on the wiping cloth 5, the cloth-clamping claw 402 is capable of contacting and clamping the wiping cloth 5.

It should be pointed out that when the cloth-clamping claw 402 in the embodiment of the specification moves outward in the cloth-clamping receiving groove 3, the cloth-clamping claw may move downward synchronously (in the embodiment of the specification, the cloth-clamping claw is hinged and swings specifically), so that the cloth-clamping claw 402 is capable of abutting against the plane of the wiping surface 201 (when the wiping surface 201 is placed on the wiping cloth 5, the cloth-clamping claw 402 may move to abut against the wiping cloth 5).

In some embodiments, as shown in FIG. 18 and FIG. 19, a pressing structure is arranged in the mop head 2; and when the cloth-clamping claw 402 is opened, the pressing structure enables the cloth-clamping claw 402 to move toward one side of the wiping surface 201 to draw close. In the embodiment, the pressing structure is a convex guiding edge 208 arranged on an upper inner wall of the mop head 2. A plurality of convex guiding edges 208 may be arranged in a spaced manner in a linear direction. The convex guiding edges 208 are configured to, when the cloth-clamping claw 402 is opened, provide a thrust, to the cloth-clamping claw 402 to enable the cloth-clamping claw to move toward one side of the wiping surface 201 all along. An avoidance groove 4021 is formed in the cloth-clamping claw 402, and after the cloth-clamping claw 402 retracts inward, the convex guiding edge 208 is arranged in the avoidance groove 4021.

In this structure, when the cloth-clamping claw 402 is opened, the convex guiding edge 208 will be separated from the avoidance groove 4021, and in this case, the convex guiding edge 208 will press the cloth-clamping claw 402, so that the cloth-clamping claw 402 swings relative to the supporting arm 401. The convex guiding edge 208 drives the cloth-clamping claw 402 to swing, so that the structure is simple and reliable to drive. The convex guiding edge 208 and the mop head 2 may be of an integrated structure. When the cloth-clamping claw 402 retracts inward into the mop head 2, the convex guiding edge 208 is placed in the avoidance groove 4021 again for avoidance, so that the design is skillful.

In some embodiments, the pressing structure is an elastic member mounted on the cloth-clamping claw 402. The elastic member is configured to enable the cloth-clamping claw 402 to have a movement trend of swinging toward one side of the wiping surface 201 all along. When the supporting arm 401 of each of the cloth-clamping mechanisms 4 drives the cloth-clamping claw 402 to slide outward to be opened, the elastic member drives the cloth-clamping claw 402 to enable the cloth-clamping claw to be lower than the wiping surface 201 (the cloth-clamping claw 402 has the trend of moving toward one side of the wiping surface 201 all along to grab the wiping cloth 5).

In an example, as shown in FIG. 8, the elastic member includes a torsional spring 6 mounted at a hinge of the cloth-clamping claw 402, one end of the torsional spring 6 is mounted on the supporting arm 401, and the other end of the torsional spring is placed on the cloth-clamping claw 402.

In some embodiments, as shown in FIG. 1 and FIG. 10, the cloth-clamping claw 402 includes equally spaced convex tooth parts 403 arranged in a staggered manner, and the staggered convex tooth parts 403 are configured to stably grab the wiping cloth 5, so that the grabbing area of the wiping cloth 5 is effectively increased.

In some preferred embodiments, referring to FIG. 5, each of the guide plates 202 is provided with a groove 207 corresponding to each of the convex tooth parts 403, and the wiping cloth 5 is clamped in the groove 207, so that the frictional force and the clamping force of the clamped wiping cloth 5 are increased in a concave-convex clamping manner.

FIG. 13 and FIG. 14 are schematic diagrams where each of the cloth-clamping mechanisms 4 on the mop head 2 is in the opened state.

As shown in FIG. 15, the wiping cloth 5 is integrally greater than the mop head 2 in length and width dimensions (in the figure, the wiping cloth 5 is only for reference, and the length and width dimensions may be designed and optimized separately).

As shown in FIG. 10, in one preferred embodiment, the convex tooth parts 403 are eccentrically conical, so that the convex tooth parts 403 are staggered on the cloth-clamping claw 402. The convex tooth parts 403 in the embodiment of the specification are different from existing tooth part structures in a simple linear array layout. The eccentrically arranged convex tooth parts 403 are staggered on the cloth-clamping claw 402, which is beneficial for the convex tooth parts 403 to better clamp the wiping cloth 5, thereby ensuring accurate and reliable cloth clamping when the wiping cloth 5 is replaced every time.

In some preferred embodiments, as shown in FIG. 5, each of the guide plates 202 is provided with a locking tooth 203 between two adjacent convex tooth parts 403, where the locking tooth 203 faces towards the cloth-clamping receiving groove 3. The locking tooth 203 is higher than each of the guide plates 202. The locking tooth 203 plays a role in clamping the wiping cloth 5 in an assisting manner.

As shown in FIG. 5, in an example, the locking tooth 203 is a sawtooth part.

In some embodiments, as shown in FIG. 20 and FIG. 21, a driving frame 406 is slidably mounted in the mop head 2, a plurality of pairs of inclined guide grooves 4061 are formed in the driving frame 406 in a spaced manner in the length direction, inclined guide pillars 4011 matching with the inclined guide grooves 4061 are arranged on the supporting arm 401, and the inclined guide pillars 4011 are placed in corresponding inclined guide grooves 4061; and the plurality of pairs of inclined guide grooves 4061 and the inclined guide pillars 4011 match to drive the cloth-clamping claw 402 to have a plurality of clamping points. When the cloth-clamping claw 402 is longer, if it is driven and clamped at both ends (i.e., both sides are the clamping points), the cloth-clamping claw 402 is easy to deform. This structure uses the plurality of clamping points to prevent the cloth-clamping claw 402 from deforming, so that it is more reliable to clamp the cloth.

The driving cam 9 is rotatably mounted at an end of the mop rod 1. The mop rod 1 is of a twisted rod structure. The mop rod 1 may drive the driving cam 9 to rotate. The mop rod 1 of the twisted rod structure belongs to the prior art, which is not described in detail herein. An eccentric pillar 901 is arranged on the driving cam 9, a guide groove 4062 matching with the eccentric pillar 901 is formed in the driving frame 406, and the eccentric pillar 901 is placed in the guide groove 4062. During driving, the mop rod 1 may drive the driving cam 9 to rotate, the driving cam 9 drives the driving frame 406 to slide through the eccentric pillar 901, and the driving frame 406 drives the supporting arm 401 to slide, so that the supporting arm 401 drives the cloth-clamping claw 402 to move outward or inward.

In some embodiments, as shown in FIG. 4 and FIG. 13, the driving mechanism includes a driving gear shaft 7 rotationally mounted on the mop head 2. Specifically, the driving gear shaft 7 in the embodiment of the specification is rotationally fastened to the mop head 2. As shown in FIG. 9, the supporting arm 401 is correspondingly provided with a meshing rack 404 meshing with the driving gear shaft 7. The mop rod 1 is in transmission connection to the driving gear shaft 7, and the mop rod 1 drives the driving gear shaft 7 to rotate, so that each of the cloth-clamping mechanisms 4 is switched between the opened state and the inward-retracted reset state.

It should be pointed out that a specific structure of the mop rod 1 realizing rotation of the driving gear shaft 7 is not limited in the embodiment of the specification, and the mop rod 1 may be rotated circumferentially (clockwise rotation or anticlockwise rotation) to control the driving gear shaft 7 to rotate to switch the state of each of the cloth-clamping mechanisms 4. The mop rod 1 may also be axially pressed (a vertical movement is switched to the rotating movement of the driving gear shaft 7 through the twisted rod structure) to control the driving gear shaft 7 to rotate to switch the state of each of the cloth-clamping mechanisms 4. As shown in FIG. 4, in an example, power is transmitted by way of transmission connection of the twisted rod, which is not specifically described in the embodiment of the specification. When the dirty wiping cloth 5 is taken down, the mop rod 1 drives the driving gear shaft 7 to rotate, so that each of the cloth-clamping mechanisms 4 is switched to the opened state, and in this case, the dirty wiping cloth 5 may be detached (in this case, the dirty wiping cloth 5 may be treaded to ensure that it is completely separated from the mop head 2).

In some embodiments, referring to FIG. 12, a guiding fastener 204 is arranged on the mop head 2 and a guiding catching groove 405 in sliding fit with the guiding fastener 204 is formed in the supporting arm 401. Through sliding fit between the guiding fastener 204 and the guiding catching groove 405, the supporting arm 401 is slidably positioned in the cloth-clamping receiving groove 3 of the mop head 2.

Specifically, in combination with FIG. 1, FIG. 5, FIG. 6, and FIG. 7, the mop head 2 includes an upper cover 205 and a lower cover 206 that are interlocked with each other, and the upper cover 205 and the lower cover 206 are spliced to form the cloth-clamping receiving groove 3; and the guiding fastener 204 is arranged on the upper cover 205, each of the guide plates 202 is arranged on the lower cover 206, and the wiping surface 201 is located on one side of a bottom end of the lower cover 206. A decorative bottom plate is mounted at the bottom of the lower cover 206 to form the wiping surface 201.

It should be pointed out that the wiping surface 201 in this application is flat in structure, so that the entire mop head 2 is simple and attractive in structure.

As shown in FIG. 4 and FIG. 6, the section of the lower cover 206 is integrally in an isosceles trapezoid shape (its bevel edges are structures of the guide plates 202).

In some embodiments, as shown in FIG. 1 and FIG. 4, a guide sleeve 8 is sleeved over the mop rod 1, and the guide sleeve 8 is mounted in a hinged manner on the mop head 2 through a universal joint 801, so that the mop rod 1 is capable of rotating in the front-back direction or the left-right direction, which is not described in detail in the embodiment of the specification.

For the same or similar parts between the embodiments in the specification, reference may be made to each other. Each embodiment focuses on differences from other embodiments.
