[0116] To facilitate understanding of the present invention, the present invention will be described in more detail below with reference to the relevant drawings. Preferred embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described below. On the contrary, the purpose of providing these embodiments is to enable a more thorough and comprehensive understanding of the disclosure of the present invention. The following references to directions such as "axial direction", "above", "below", etc. are intended to more clearly illustrate the structural position relationship and are not limitations on the present invention. In the present invention, the definition of "vertical", "horizontal", and "parallel" is: including situations within ±10% of the standard definition. For example, vertical usually refers to an angle of 90 degrees relative to the reference line, but in the present invention, vertical refers to situations within 80 to 100 degrees.

[0117] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are intended to explain the present invention but the present invention is not limited to the following examples.

[0118] See also Figures 1 to 46 The flat mop of the embodiment of the present invention comprises a handle 1, a panel 2, a mop cloth 3, a control unit, and a clamping unit. The mop cloth 3 can be a non-woven fabric in the prior art.

[0119] The handlebar 1 in this embodiment may adopt a telescopic structure or a multi-section detachable structure in the prior art, which will not be described in detail here.

[0120] The panel 2 in this embodiment is connected to the handlebar 1. Furthermore, the panel 2 can be connected to the handlebar 1 via a joint. The joint can be a universal joint.

[0121] The mop 3 in this embodiment can be made of conventional non-woven fabric. The mop 3 can be secured by a clamping unit, which adheres to the bottom of the panel 2. Specifically, the clamping unit is disposed on the panel 2 and configured to clamp the edge of the mop 3 together with the edge of the panel 2. It includes a movable portion and an elastic unit. The elastic unit acts on the movable portion, clamping the edge of the mop 3 between the movable portion and the edge of the panel 2. A first tooth portion 201 is provided on the side of the panel 2, while a second tooth portion 501 corresponding to the first tooth portion 201 is provided on the movable portion. This enhances the stability of the mop 2 and prevents it from falling off. The first tooth portion 201 and the second tooth portion 501 can be staggered to provide a better clamping effect.

[0122] The control unit in this embodiment is configured to overcome the force of the elastic unit, thereby controlling the movable portion to move, so as to release the mop 3 clamped between the movable portion and the edge of the panel 2 .

[0123] The panel 2 in this embodiment may include a bottom plate 21 and a top plate 22, which are fixed to each other, with the handle 1 connected to the top plate 22. The bottom plate 21 of the panel 2 in this embodiment is provided with a foam 6, which fits in contact with the mop 3. This not only increases the friction coefficient between the mop 3 and the panel 2, preventing the mop 3 from sliding relative to the panel 2, but also provides elastic support for the mop 3, thereby improving user comfort and cleaning performance.

[0124] In this embodiment, the edge of the mop 3 is folded when clamped to form a folded portion, which is clamped between the panel 2 and the movable portion, and the edge of the mop 3 is exposed outside the movable portion and the panel 2 to form a free portion 31. Through the free portion 31, the mop 3 can be easily pulled off when disassembling.

[0125] like Figures 1 to 7 As shown, in a first embodiment, the control unit 41 includes an actuating portion 411 and a sliding portion 412, wherein the actuating portion 411 has a pressing portion 4111 exposed to the outside of the panel 2 and a supporting surface 4112 located inside the panel 2, and the sliding portion 412 has a pushing surface 4121 that cooperates with the supporting surface 4112. When the actuating portion 411 is pressed downward, the supporting surface 4112 pushes against the pushing surface 4121 of the sliding portion 412, causing the sliding portion 412 to slide. At this time, the sliding portion 412 pushes the movable portion 51, causing the second tooth portion 501 of the movable portion 51 to separate from the first tooth portion 201 of the panel 2. In this embodiment, the sliding portion 412 is fixed to the movable portion 51 to achieve linkage.

[0126] In this embodiment, the elastic unit is a spring 502 , and the spring 502 acts on the sliding portion 412 or the movable portion 51 .

[0127] In this embodiment, when installing the mop, the actuating portion 411 is pressed downward, causing the sliding portion 412 to overcome the force of the spring 502 and open the movable portion 51 relative to the panel 2. The edge of the mop 3 is placed between the movable portion 51 and the panel 2. After releasing the actuating portion 411, the sliding portion 412 and the movable portion 51 return to their original position under the action of the spring 502, thereby clamping the mop 3.

[0128] In this embodiment, to remove the mop cloth 3, the actuator 411 is pressed, causing the sliding portion 412 to overcome the force of the spring 502 and open the movable portion 51 relative to the panel 2. The mop cloth 3 can then be removed. If sufficient force is applied, the mop cloth 3 can also be directly pulled off while being held between the movable portion 51 and the panel 2.

[0129] In this embodiment, the control unit 41 may also include a handle 413, which is mounted on the handlebar 1 and can move along the length direction of the handlebar 1. The end of the handle 413 corresponds to the actuating part 411. When the handle 413 is pressed down, the actuating part 411 can be pressed down for control without directly pressing the actuating part 411 with the hand.

[0130] In this embodiment, the actuating portion 411 , the sliding portion 412 and the movable portion 51 are each provided in two groups. When the handle 1 is pressed down, the two groups of the actuating portions 411 can be pressed down simultaneously for simultaneous control.

[0131] In this embodiment, a first positioning portion 4131 is provided on the handle 413, and a second positioning portion 11 is provided on the handlebar 1. When the first positioning portion 4131 cooperates with the second positioning portion 11, the handle 413 can be positioned at a position on the handlebar 1 to prevent the handle 413 from affecting normal use.

[0132] The first positioning portion 4131 is an annular protrusion, and the second positioning portion 11 is a positioning groove that matches the annular protrusion. When force is applied to the handle 413, the first positioning portion 4131 can be separated from the second positioning portion 11.

[0133] In this embodiment, the movable portion 51 slides relative to the panel 2. The movable portion 51 has a positioning portion 511, and the panel 2 has a guide rail groove 201. The positioning portion 511 fits in the guide rail groove 201 to increase the stability of the movable portion 51 when sliding.

[0134] In this embodiment, a channel 202 is formed on the panel 2 for accommodating the actuating portion 411 , and both ends of the channel 202 have stop structures to restrict the actuating portion 411 and prevent the actuating portion 411 from escaping.

[0135] In this embodiment, a sliding groove 203 is formed on the panel 2 for disposing the sliding portion 412 to improve the stability of the sliding portion 412 during sliding.

[0136] like Figures 1 to 7 As shown, in this embodiment, the movable portions 51 are disposed on both sides of the panel 2 in the longitudinal direction, so that the mop 3 is fixed on both sides in the longitudinal direction.

[0137] like Figure 8 As shown, in some embodiments, movable portions 51 are provided on both sides of the panel 2 in the width direction, thereby securing the mop 3 on both sides of the panel 2 in the width direction. In this embodiment, the sliding portion is omitted, and the movable portion 51 is directly pushed by the actuator 411. The basic structure and control principle of the flat mop in this embodiment are similar to those of the first embodiment and will not be further described here.

[0138] like Figures 9 to 17As shown, in a second embodiment, the control unit 42 includes an actuating portion 421 and a sliding portion 422, wherein the actuating portion 421 includes a wrench 4211, a linkage unit 4212, and an actuating portion 4213. The wrench 4211 is disposed on the handlebar 1, and the wrench 4211 controls the linkage unit 4212 to move along the axial direction of the handlebar 1, so that the linkage unit 4212 drives the actuating portion 4213 to move. The actuating portion 4213 cooperates with the sliding portion 422. When the actuating portion 4213 is pressed downward, the sliding portion 422 is driven to slide, thereby actuating the movable portion 52. By arranging the wrench 4211 on the handlebar 1, its operation is more convenient.

[0139] In this embodiment, the linkage unit 4212 is a pressure rod, and the wrench 4211 is hinged to the handle 1. When the wrench 4211 is pressed, the wrench 4211 can push the pressure rod along the axial direction of the handle 1. The pressure rod can be directly or indirectly connected to the action part 4213 to control the action part 4213 to press downward.

[0140] In some embodiments, a spring may be provided at the handle 1 to apply force to the wrench 4211 . After the force applied to the wrench 4211 is removed, the wrench 4211 may recover under the action of the spring.

[0141] In some embodiments, a spring is provided at the pressure rod to apply force to the pressure rod. After the force applied to the wrench 4211 is removed, the pressure rod can be restored under the action of the spring, and the pressure rod can force the wrench 4211 to restore.

[0142] In this embodiment, the action portion 4213 has a push surface 42131, and the sliding portion 422 has an inclined surface 4221 that matches the push surface 42131. Through the cooperation between the push surface 42131 and the inclined surface 4221, the longitudinal movement of the action portion 4213 can be converted into the lateral movement of the sliding block 422.

[0143] In this embodiment, the movable portion 52 has a hinge 521, and the panel 2 has a shaft hole 204, and the hinge 521 fits into the shaft hole 204. When the sliding portion 422 pushes the movable portion 52, the movable portion 52 can be rotated to open, so as to clamp the mop 3.

[0144] The shaft hole 204 is configured in an oblong shape and is tilted downwardly away from the sliding portion 422. The oblong shape of the shaft hole 204 increases the extent to which the movable portion 52 can be extended relative to the panel 2, facilitating operation. Furthermore, the downward tilt of the shaft hole 204 away from the sliding portion 422 makes it easier to control the rotation of the movable portion 52 and prevents it from getting stuck.

[0145] The movable portion 52 includes a rotating portion 522 and a side plate 523, wherein the second tooth portion 501 is disposed on the side plate 523. The rotating portion 522 is rotatably connected to the side plate 523 to further increase the extent to which the side plate 523 can be expanded.

[0146] In this embodiment, the elastic unit 524 forces the side panels 523 to retract relative to the panel 2. When no external force is applied, the movable portion 52 (side panels 523) and the panel 2 clamp the edge of the mop 3. The elastic unit 524 can be a spring, with one end connected to the side panels 523 and the other end connected to the panel 2.

[0147] In this embodiment, an elastic component 525 may be further included. The elastic component includes a top block 5251 and a spring 5252. The top block 5251 cooperates with the sliding portion 422, and one end of the spring 5252 cooperates with the top block 5251, while the other end cooperates with the panel 2. This allows the elastic component 525 to generate elastic potential energy for the sliding portion 422. When the operating portion 4213 presses downward to cause the sliding portion 422 to slide, the spring 5252 of the elastic component accumulates elastic potential energy. When the force applied by the operating portion 4213 to the sliding portion 422 is removed, the sliding portion 422 returns to its original position under the action of the elastic component 525.

[0148] In this embodiment, a sliding groove 203 may also be provided on the panel 2 for accommodating the sliding portion 422 , so as to improve the stability of the sliding portion 422 during sliding.

[0149] like Figures 9 to 17 As shown, in this embodiment, the movable portions 52 are disposed on both sides of the panel 2 in the longitudinal direction, so that the mop 3 is fixed on both sides in the longitudinal direction.

[0150] like Figure 18 As shown, in some embodiments, the movable portion 52 is disposed on both sides of the panel 2 in the width direction, thereby securing the mop 3 on both sides of its width. However, in this embodiment, the sliding portion is omitted, and the movable portion 52 is directly pushed by the action portion 4213. Alternatively, the movable portion and the sliding portion can be integrated into a single structure. In this embodiment, the action portion 4213 is provided with a push surface 42131, while the movable portion 52 is provided with an inclined surface 5201. When the action portion 4213 is pressed downward, the push surface 42131 acts on the inclined surface 5201, causing the movable portion 52 to slide and unfold relative to the panel 2.

[0151] In this embodiment, the movable portion 52 can achieve directional movement through the orientation unit and the panel 2. The orientation unit may include a guide groove 5202 provided on the movable portion 52 and a positioning block 205 provided on the panel 2. The positioning block 205 is confined in the guide groove 5202 so that it can only slide in a limited direction and range.

[0152] In this embodiment, the elastic unit is a spring 526, whose ends engage the movable portion 52 and the panel 2, respectively. When the actuating portion 4213 presses downward, pushing the movable portion 52, the movable portion 52 generates elastic potential energy in the spring 526. When the force exerted by the actuating portion 4213 is removed, the movable portion 52 returns to its original position and clamps the mop 3 between the panel 2.

[0153] like Figures 19 to 23 As shown, in a third embodiment, the control unit 43 includes an actuating portion 431 and a sliding portion 432, wherein one end of the actuating portion 431 is exposed to the outside of the panel 2, and a pushing surface 4311 is provided at the other end, and an inclined surface 4321 is provided on the sliding portion 432 to cooperate with the pushing surface 4311. After pressing the actuating portion 431, the pushing surface 4311 acts on the inclined surface 4321 to make the sliding portion 432 slide, thereby driving the movable portion 53.

[0154] In this embodiment, a button 4322 is provided on the sliding portion 432. At least a portion of the button 4322 is exposed outside the panel 2. This allows the user to press the button 4322 to directly push the sliding portion 432, thereby controlling the device. The button 4322 and the actuator 431 have different movement directions, providing different operating methods. The button 4322 and the sliding portion 432 are integrally formed.

[0155] In this embodiment, the actuator 431 can be pressed downward to push the sliding portion 432, or the button 4322 can be pressed laterally to directly push the sliding portion, allowing for convenient operation based on user preferences. Furthermore, in this embodiment, even if either the actuator 431 or the button 4322 fails, the other can still be used for operation.

[0156] The basic structure of the movable portion 53 in this embodiment is similar to that of the movable portion in the second embodiment. Specifically, the movable portion 53 in this embodiment includes a rotating portion 532 and a side plate 533, wherein the second tooth portion 501 is disposed on the side plate 533. The rotating portion 532 is rotatably connected to the side plate 533 to further increase the range of the side plate 533 that can be expanded.

[0157] In this embodiment, an elastic unit forces the side panels 533 to retract relative to the panel 2. In the absence of external force, the movable portion 53 (side panels 523) and the panel 2 clamp the edge of the mop 3. The elastic unit can be a spring 531, one end of which is connected to the side panels 533 and the other end to the panel 2. Simultaneously, when the spring 531 applies force to the movable portion 53, it indirectly applies force to the sliding portion 432, forcing the sliding portion 432 to return to its original position.

[0158] In this embodiment, a corresponding sliding groove 203 may also be provided on the panel 2 to accommodate the sliding portion 432 , so as to improve the sliding stability of the sliding portion 432 .

[0159] like Figures 19 to 23 As shown, in this embodiment, the movable portions 53 are disposed on both sides of the panel 2 in the longitudinal direction, so that the mop 3 is fixed on both sides in the longitudinal direction.

[0160] like Figures 24 to 26 As shown, in some embodiments, the movable portion 53 is disposed on both sides of the panel 2 in the width direction, and its basic structure is the same as that of the third embodiment. The difference is that the button 4322 is formed as a separate component, with a first inclined surface 43221 disposed on the button 4322, and a second inclined surface 4323 corresponding to the first inclined surface 43221 is disposed on the sliding portion 431. When the button 4322 is pushed, the first inclined surface 43221 acts on the second inclined surface 4323, pushing the sliding portion 432 in the width direction of the panel 2. In addition, in this embodiment, the movable portion 53 and the sliding portion 431 are integrally formed and can move along the width direction of the panel 2 to expand or contract relative to the width edge of the panel 2.

[0161] In this embodiment, the basic structure and control principle of the flat mop are substantially the same as those of the third embodiment and will not be described in detail here.

[0162] like Figures 27 to 33 As shown, in a fourth embodiment, the control unit 44 includes an actuating portion 441 and a sliding portion 442, wherein the actuating portion 441 and the sliding portion 442 are fixed as one body. In other words, the actuating portion 441 and the sliding portion 442 can be an integrated structure or a separate structure but fixed as one body.

[0163] The actuating portion 441 includes a button 4411 exposed outside the panel 2 . When the button 4411 is pressed laterally of the panel 2 , the sliding portion 442 is directly pushed, thereby opening the movable portion 54 relative to the panel 2 .

[0164] In this embodiment, the basic structure of the movable portion 54 and the connection structure between the movable portion 54 and the panel 2 are the same as those in the first embodiment. Specifically, in this embodiment, the movable portion 54 slides relative to the panel 2. The movable portion 54 has a positioning portion 541, and the panel 2 has a guide rail groove 206. The positioning portion 511 fits within the guide rail groove 206 to enhance the stability of the movable portion 54 during sliding.

[0165] In this embodiment, the sliding portion 442 can be fixedly connected to the movable portion 54. In some embodiments, the sliding portion 442 can also be integrally formed with the movable portion 54.

[0166] In this embodiment, a locking unit 7 may be further included, which cooperates with the actuating portion 441 to fix its position when the button 4411 of the actuating portion 441 is pressed, so as to open the movable portion 54 relative to the panel 2 to facilitate the installation of the mop 3.

[0167] The locking unit 7 includes a locking block 71 and a first spring 72. The locking block 71 presses against the first spring 72 and has a guide surface 711 and a locking surface 712. The guide surface 711 and the locking surface 712 mate with the button 4411 in different positions of the button 4411. The guide surface 711 mates with the button 4411. When the button 4411 is pressed, the button 4411 slides across the guide surface 711, causing the locking block 71 to press down the first spring 72. When the button 4411 passes over the locking block 71, the locking block 71 rebounds under the action of the first spring 72 and locks the button 4411 via the locking surface 712. This allows the movable portion 54 to be opened relative to the panel 2, facilitating assembly and disassembly of the mop 3.

[0168] In this embodiment, the elastic unit is a spring 542 , which applies force to the sliding portion 442 or the movable portion 54 , so that the movable portion 54 is clamped relative to the panel 2 in a normal state (without external force).

[0169] In this embodiment, a release unit 8 may be further included. The release unit 8 cooperates with the locking unit 7 and is configured to release the locking unit 7 from locking the button 4411 .

[0170] The release unit 8 includes a locking sleeve 81 and a second spring 82. The locking block 71 is mounted on the locking sleeve 81. The locking sleeve 81 is located inside the panel 2 and compresses the second spring 82. When the locking sleeve 81 is pressed, it pulls the locking block 71 downward, thereby releasing the button 4411. The actuator 441 returns to its original position under the action of the elastic unit, allowing the movable portion 54 and the panel 2 to clamp the edge of the mop 3. As in the previous embodiment, the edge of the mop 3 can also form a free portion 31.

[0171] The locking sleeve 81 has a locking portion 811 with a hole 8111 . The locking block 71 has a stopping surface 713 . A portion of the locking block 71 passes through the hole 8111 and is stopped at the bottom of the hole 8111 of the locking portion 811 by the stopping surface 713 .

[0172] In this embodiment, the handlebar 1 engages with the locking sleeve 81. When the handlebar 1 is pressed downward, the locking sleeve 81 is also pressed downward. Specifically, the joint 12 at the end of the handlebar 1 has a hinge 121, which abuts against the locking sleeve 81. When the hinge 121 engages with the panel 2, it has room to move up and down, allowing it to press the locking sleeve 81 downward.

[0173] In this embodiment, a sliding groove 203 may also be formed on the panel 2 for setting the sliding portion 4442 to improve the stability of the sliding portion 442 during sliding.

[0174] like Figures 17 to 33As shown, in this embodiment, the movable portions 54 are disposed on both sides of the panel 2 in the longitudinal direction, so that the mop 3 is fixed on both sides in the longitudinal direction.

[0175] like Figures 34 to 36 As shown, in some embodiments, movable portions 54 are provided on both sides of the panel 2 in the width direction, thereby securing the mop 3 on both sides of the panel 2 in the width direction. The basic structure of this embodiment is the same as that of the fourth embodiment. The difference is that this embodiment does not require a sliding portion, but instead directly drives the movable portion 54 via an actuator 441. Specifically, the actuator 441 includes a button 4411 having a push surface 44111, while the movable portion 54 has an inclined surface 543. When the button 4411 is pressed, the push surface 44111 acts on the inclined surface 543, pushing the movable portion 54 to slide, thereby opening the movable portion 54 relative to the panel 2.

[0176] The basic structures of the locking unit 7 and the releasing unit 8 in this embodiment are the same as those in the fourth embodiment, and will not be described again here.

[0177] like Figures 37 to 42 As shown, in a fifth embodiment, the control unit 45 includes an actuating portion 451 and a sliding portion 452 . The sliding portion 452 is disposed in the panel 2 and connected to the movable portion 55 .

[0178] The elastic unit applies force to the sliding portion 452 or the movable portion 55, so that the movable portion 55 can be expanded relative to the panel 2 under the action of the elastic unit when there is no external force. Specifically, the elastic unit can be a spring 552, and the two ends of the spring 552 respectively abut against the panel 2 and the sliding portion.

[0179] In this embodiment, a locking unit 75 may also be included. When engaged with the sliding portion 452, the locking unit 75 is locked. When the panel 2 and the movable portion 55 are clamped together, the movable portion 55 is positioned to maintain the clamped state between the panel 2 and the movable portion 55. In this embodiment, since the sliding portion 452 is connected to the movable portion 55, the locking unit 75 can also serve the same purpose by positioning the sliding portion 452.

[0180] The locking unit 75 includes a locking block 751 and a first spring 752. The first spring 752 applies force to the locking block 751. The sliding portion 452 has a locking hole 4521 (or locking groove). In the locked state, the locking block 751 is pressed downward by the first spring 752 and fits into the locking hole 4521 to limit the sliding of the sliding portion 452, thereby locking the movable portion 54 and preventing it from loosening relative to the panel 2 and causing the mop 3 to fall out.

[0181] The actuator 451 has a push surface 4511, and the locking block 751 has a first inclined surface 7511 that mates with the push surface 4511. When the actuator 451 is pressed, the push surface 4511 acts on the first inclined surface 7511, causing the locking block 751 to overcome the force of the first spring 752 and move upward, releasing it from the locking hole 4521. At this point, the sliding portion 452, under the action of the elastic unit (spring 552), drives the movable portion 55 to automatically expand relative to the panel 2, facilitating the removal of the mop 3.

[0182] In this embodiment, the control unit 45 further includes a trigger 453, which includes a pressing surface 4531. The sliding portion 452 is provided with an action surface 4522 that cooperates with the pressing surface 4531. When the trigger 453 is pressed down, the pressing surface 4531 acts on the action surface 4522 to slide the sliding portion 452 and drive the movable portion 55 to clamp the mop 3 relative to the panel 2 until the locking block 751 is re-engaged in the locking hole 4521, and finally the sliding portion 452 is locked by the locking block 751.

[0183] In this embodiment, the locking block 751 is provided with a guide surface 7512 that cooperates with the sliding portion 452. When the trigger 453 pushes the sliding portion 452, the sliding portion 452 pushes against the guide surface 7512, thereby allowing the locking block 751 to slide upward, overcoming the force of the first spring 752. When the locking block 751 is aligned with the locking hole 4521 in the sliding block 452, the locking block 751 is downwardly inserted into the locking hole 4521. In other words, the provision of the guide surface 7512 allows the sliding portion 452 to easily slide past the locking block 751.

[0184] In this embodiment, the handle 1 controls the downward movement of the trigger 453. The specific principles behind this control are similar to those used in the fourth embodiment to control the release mechanism. Specifically, the handle 1 cooperates with the trigger 453. When the handle 1 is pressed downward, the trigger 453 is forced downward. The joint 12 at the end of the handle 1 includes a hinge 121, which abuts against the trigger 453. When the hinge 121 engages the panel 2, it has room to move upward and downward, allowing it to depress the trigger 453.

[0185] In this embodiment, a second spring 454 is provided to cooperate with the trigger 453. Specifically, the two ends of the second spring 454 are respectively connected to the panel 2 and the trigger 453, and provide an upward force on the trigger 453. Therefore, when there is no external force on the trigger 453, it will not actively press the actuating surface 4522, and misoperation can be prevented.

[0186] like Figures 37 to 42 As shown, in this embodiment, the movable portions 55 are disposed on both sides of the panel 2 in the longitudinal direction, so that the mop 3 is fixed on both sides in the longitudinal direction.

[0187] like Figures 43 to 46 As shown, in some embodiments, movable portions 55 are provided on both sides of the panel 2 in the width direction, thereby securing the mop 3 on both sides of its width. The basic structure of this embodiment is the same as that of the fifth embodiment, with only adjustments made to the structural adaptability of the components. For example, the locking block 751 is positioned upward and engages with the locking hole 4521 of the sliding portion 452 (if the sliding portion 452 is not provided, the locking hole can be provided on the movable portion 55).

[0188] In this embodiment, the basic structure and control principle of the flat mop are substantially the same as those of the third embodiment and will not be described in detail here.
