DETAILED DESCRIPTION

[0027] In order to enable those skilled in the art to better understand the solution of the utility model, the following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0028] like Figures 2 - 7 As shown, a flat mop squeezing and cleaning mechanism includes a water squeezing frame 1, a water squeezing channel 11, an extruding member 3, a cavity 4, and a regulating unit 5.

[0029] The squeezing channel 11 is formed on the squeezing frame 1, into which the flat mop 2 is inserted, and the flat mop 2 can be pulled, pushed, or pulled relative to the squeezing channel 11. In other words, the flat mop 2 and the squeezing channel 11 move relative to each other to achieve the up and down pulling, pushing, and pulling of the flat mop 2. Of course, the squeezing channel 11 can also be formed by partially combining the squeezing frame 1 and the cavity 4, and there is no specific limitation.

[0030] The cavity 4 is arranged on the water squeezing rack 1 and is used for storing the cleaning body. The cleaning body is not limited either. It can be a liquid cleaning agent or a solid cleaning soap, such as soap, etc. In this embodiment, a liquid cleaning body is selected. Regarding the arrangement of the cavity 4 on the water squeezing rack 1, the cavity 4 can be arranged as an independent component within the water squeezing rack 1, that is, the cavity 4 is separately arranged from the water squeezing rack 1; or a part of the cavity 4 is connected to the water squeezing rack 1 integrally, and the other part of the cavity 4 is relatively independent. The structure here also corresponds to the formation of the water squeezing channel 11. That is, when the water squeezing rack 1 and the cavity 4 are relatively independent, the water squeezing channel 11 is formed by the water squeezing rack 1. When a part of the water squeezing rack 1 and the cavity 4 are connected together, the water squeezing channel 11 is formed by the partial combination of the water squeezing rack 1 and the cavity 4. Of course, the cavity 4 may not be a relatively independent component, and it can generally be understood as the partial structure corresponding to storing the cleaning body. A cleaning body outlet 41 is arranged on one side of the cavity 4 facing the water squeezing channel 11.

[0031] The squeezing member 3 faces the water squeezing channel 11 and is used for squeezing the wiping object of the flat mop 2. The squeezing member 3 can be arranged on the water squeezing rack 1 or on the cavity 4, and there is no specific limitation.

[0032] The control unit 5 can cooperate with the flat mop 2 to open or close the cleaning body outlet 41 on the cavity 4. When the cleaning body outlet 41 is opened, the cleaning body in the cavity 4 can be delivered to the wiping object of the flat mop 2. At this time, the wiping object of the flat mop 2 adheres to the cleaning body for deep cleaning, making the cleaning effect of the flat mop 2 better; when the cleaning body outlet 41 is closed, the cleaning body in the cavity 4 cannot be delivered to the wiping object of the flat mop 2. At this time, the flat mop 2 mainly performs rinsing to avoid the wiping object of the flat mop 2 still retaining a large amount of cleaning body when mopping the floor.

[0033] The control unit 5 has a working state and a waiting state. In the working state, under the up and down pulling and pushing of the flat mop 2, the control unit 5 opens or closes the cleaning body outlet 41. In the waiting state, when the flat mop 2 is pulled and pushed up and down, the control unit 5 will not open or close the cleaning body outlet 41 either. Specifically, the switching between the working state and the waiting state of the control unit 5 can be that the control unit 5 and the cavity 4 move away from the water squeezing channel 11 together, so that even if the flat mop 2 is pulled and pushed up and down, it will not contact the control unit 5; it can also be that the control unit 5 moves away from the cavity 4, so that even if the flat mop 2 is pulled and pushed up and down and contacts the driving control unit 5, the control unit 5 cannot contact the cavity 4; or the control unit 5 can be locked to prevent it from switching between the two states.

[0034] Of course, in other embodiments, the control unit 5 can also be a switch arranged at the cleaning body outlet 41, so that the control unit 5 can directly open or close the cleaning body outlet 41. Specifically, existing switch devices in the prior art can be selected.

[0035] In this embodiment, the opening or closing of the cleaning body outlet 41 is achieved by controlling the movement of a part of the control unit 5. In the working state, at least a part of the control unit 5 moves under the up-and-down pulling and pushing of the flat mop 2, so as to open or close the cleaning body outlet 41; in the waiting state, the control unit 5 stops moving, that is, under the up-and-down pulling and pushing of the flat mop 2, the control unit 5 will not move, so as not to open or close the cleaning body outlet 41.

[0036] As Figure 6 、 Figure 7 shown, the control unit 5 includes a rotating body 51, an eccentric wheel 52, and a deformable member 53 corresponding to the eccentric wheel 52. The rotating body 51 and the eccentric wheel 52 are connected by a rotating shaft 54. The rotating body 51 is concentric and coaxial with the rotating shaft 54, while the center of the eccentric wheel 52 deviates from the center of the rotating shaft 54. When the flat mop 1 is inserted into the water squeezing channel 11 and pulled up and down, its wiping object can contact the rotating body 51, thereby driving the rotating body 51 to rotate, and then driving the eccentric wheel 52 to rotate through the rotating shaft 54 that rotates synchronously with the rotating body 51.

[0037] Specifically, the number of the rotating bodies 51 is two, which are located on both sides of the eccentric wheel 52, and the deformable member 53 is arranged in the middle part of the cavity 4 or the water squeezing frame 1.

[0038] In order to realize the assembly of the control unit 5, a buckle 12 is arranged on one side of the water squeezing frame 1 facing the water squeezing channel 11, and the rotating shaft 54 is detachably connected to the buckle 12. Of course, the buckle 12 can also be arranged on the outer wall of the cavity 4, and there is no specific limitation.

[0039] The deformable member 53 is connected to the cavity 4, and its position corresponds to the position of the eccentric wheel 52. Here, the deformable member 53 is a soft rubber layer made of an elastic material. Thus, when the flat mop 2 is pulled up and down to drive the rotating body 51 to rotate, the eccentric wheel 52 can be driven to rotate. When the protruding part of the eccentric wheel 52 contacts the deformable member 53, the deformable member 53 can be pushed towards the inside of the cavity 4, so that the air pressure in the cavity 4 changes, and thus the cleaning body outlet 41 is opened, and the cleaning body in the cavity 4 is output outwards through the cleaning body outlet 41; when other parts of the eccentric wheel 52 rotate to face the deformable member 53, the eccentric wheel 52 will not contact the deformable member 53, the air pressure in the cavity 4 will not change, and thus the cleaning body outlet 41 remains closed, and the cleaning body in the cavity 4 will not be output outwards.

[0040] In this embodiment, a one-way extrusion valve 42 is connected to the cleaning body outlet 41, and its initial state is a closed state. When the air pressure on one side increases, it can be switched from the closed state to the open state. It is a conventional structure and will not be elaborated here.

[0041] As described above, the control unit 5 can be locked, so that it switches from the working state to the waiting state. As Figure 6 shown, it further includes a locking member 55. A locking recess 56 and a locking projection 57 are provided between the locking member 55 and the rotating body 51. When the locking recess 56 and the locking projection 57 are engaged, the rotating body 51 stops rotating, and at this time the control unit 5 enters the waiting state; when the locking recess 56 and the locking projection 57 are separated, the rotating body 51 can rotate freely, and at this time the control unit 5 enters the working state. Specifically, in this embodiment, the locking member 55 has a locking recess 56, and a convex tooth disc is formed on the side surface of the rotating body 51 facing the locking member 55, that is, a plurality of locking projections 57 are arranged along the circumference. In order to facilitate driving the locking member 55 to switch between approaching and departing from the rotating body 51, a part of the locking member 55 passes through the water squeezing frame 1, which is convenient for applying an external force to toggle the locking member 55.

[0042] During use, when the locking recess 56 and the locking projection 57 are separated from each other and the rotating body 51 can rotate freely, when the flat mop 2 is inserted into the water squeezing channel 11 and pulled up and down, the wiping material of the flat mop 2 drives the rotating body 51 to rotate, and then drives the eccentric wheel 52 to rotate and contact the deformation member 53, so that the cleaning body outlet 41 is opened under the condition that the air pressure in the cavity 4 changes, and the cleaning body is conveyed to the wiping material, and the wiping material is deeply cleaned. After the wiping material adheres to the cleaning body and is pulled and pushed by the squeezing member 3, the cleaning body foams sufficiently, and the deep cleaning effect of the wiping material is better; after the deep cleaning is completed, an external force is applied to the locking member 55 to make the locking recess 56 and the locking projection 57 engage with each other. At this time, the rotating body 51 cannot rotate. Even when the flat mop 2 is inserted into the water squeezing channel 11 and pulled up and down, the wiping material of the flat mop 2 cannot drive the rotating body 51 to rotate, and then cannot drive the eccentric wheel 52 to rotate and contact the deformation member 53, that is, the cleaning body outlet 41 is always in the closed state, so that the wiping material will not continue to adhere to the cleaning body. During the continuous pulling and pushing process of the wiping material and the squeezing member 3, the cleaning body on the wiping material is washed, and the rinsing process of the flat mop 3 is completed.

[0043] As described above, the regulation unit 5 can be switched between the working state and the waiting state by moving away from or close to the water squeezing channel 11. It further includes a driving assembly 6 which is used to drive the cavity 4 to move relative to the water squeezing frame 1, so that the cavity 4 moves away from or close to the regulation unit 5. At this time, the regulation unit 5 is connected to a fixed position of the water squeezing frame 1. When the cavity 4 moves away from the regulation unit 5, the regulation unit 5 is in the waiting state. Even if the rotating body 51 of the regulation unit 5 can be driven by the wiping object to rotate, since the eccentric wheel 52 cannot contact the deformation part 53 of the cavity 4, the air pressure in the cavity 4 will not change, and the cleaning body outlet 41 cannot be opened, and the cleaning body cannot convey to the wiping object. When the cavity 4 moves close to the regulation unit 5, the regulation unit 5 is in the working state. At this time, the rotating body 51 of the regulation unit 5 can be driven by the wiping object to rotate, and then the eccentric wheel 52 squeezes the deformation part 53.

[0044] Alternatively, the driving assembly 6 is used to drive the cavity 4 and the regulation unit 5 to move relative to the water squeezing frame 1 together, so that the two move away from or close to the water squeezing channel 11. When the two move away from the water squeezing channel 11 together, the regulation unit 5 enters the waiting state. When the flat mop 2 is pulled up and down, the wiping object cannot contact the rotating body 51, so the cleaning body outlet 41 cannot be opened. At this time, the regulation unit 5 can be connected to the cavity 4; when the two move close to the water squeezing channel 11 together, the regulation unit 5 enters the working state. When the flat mop 2 is pulled up and down, the wiping object contacts the rotating body 51, and the rotating body 51 rotates to drive the eccentric wheel 52 to rotate so as to contact the deformation part 53 of the cavity 4.

[0045] Or, the driving assembly 6 is used to drive the regulation unit 5 to move relative to the water squeezing frame 1, so that the regulation unit 5 moves away from or close to the cavity 4. At this time, the cavity 4 is connected to a fixed position of the water squeezing frame 1. When the regulation unit 5 moves away from the cavity 4, it enters the waiting state. When the flat mop 2 is pulled up and down, even if the rotating body 51 of the regulation unit 5 can be driven by the wiping object to rotate, since the eccentric wheel 52 cannot contact the deformation part 53 of the cavity 4, the air pressure in the cavity 4 will not change, and the cleaning body outlet 41 cannot be opened, and the cleaning body cannot convey to the wiping object. When the regulation unit 5 moves close to the cavity 4, it enters the working state.

[0046] Such as Figures 3 - 5As shown in the figure, taking the example of driving the cavity 4 to move relative to the water squeezing rack 1 by the driving component 6, at this time, the control unit 5 is connected to the fixed position of the water squeezing rack 1. The driving component 6 at least includes a shifting transverse groove 61 formed on the water squeezing rack 1, a shifting member 62 movably connected to the water squeezing rack 1, and a moving track 63 formed on the cavity 4. The shifting transverse groove 61 extends along the width direction of the water squeezing rack 1. A part of the shifting member 62 extends into the moving track 63, and a part of the shifting member 62 is located in the shifting transverse groove 61. In other words, the shifting member 62 extends into the moving track 63 after passing through the shifting transverse groove 61. By applying an external force to drive the shifting member 62 to move relative to the water squeezing rack 1 within the shifting transverse groove 61, the cavity 4 can be extended or retracted from the water squeezing rack 1, that is, the switching between the working state and the waiting state of the control unit 5 can be realized.

[0047] In this embodiment, the number of the moving tracks 63 is two. Correspondingly, two shifting portions 621 that can extend into the moving tracks 63 are provided on the shifting member 62. The moving track 63 includes a first sliding groove 631, a second sliding groove 632 arranged in parallel with the first sliding groove 631, and a transition sliding groove 633 connecting the first sliding groove 631 and the second sliding groove 632. The transition sliding groove 633 is inclined. Of course, the first sliding groove 631 and the second sliding groove 632 do not necessarily have to be completely parallel, as long as they are not on the same straight line. Specifically, the first sliding groove 631 extends along the width direction of the cavity 5. The whole moving track 63 is a Z-shaped sliding groove. Here, the Z-shaped sliding groove means that its shape trend is close to the Z shape, not necessarily a standard Z shape, and it can also be the mirror shape of Z. The first sliding groove, the second sliding groove and the transition sliding groove do not necessarily have to be straight grooves, and can also be curved grooves, as long as there is a height difference between the first sliding groove 631 and the second sliding groove 632 and they are connected to each other. The specific shape is not limited.

[0048] When an external force is applied to make the shifting member 62 move horizontally relative to the water squeezing rack 1 within the shifting transverse groove 61, due to the limitation of the shifting transverse groove 61, the two shifting portions 621 of the shifting member 62 can only move horizontally. Once they move horizontally beyond the transverse width of the first sliding groove 631 or the second sliding groove 632, they will inevitably enter the transition sliding groove 633. Since the shifting portions 621 can only move horizontally, the shifting portions 621 move against the transition sliding groove 633, and the cavity 4 expands and contracts horizontally under the drive of the shifting portions 621.

[0049] In order to make the chamber 4 stay stably in the target state position, a positioning component is also included for limiting the chamber 4 in two states, far away from the regulating unit 5 and close to the regulating unit 5. The positioning component can be any structure in the prior art. Specifically, the positioning component is a convex rib structure arranged on the water squeezing rack 1. The convex rib can be against the toggle member 62 of the driving assembly 6, so that the toggle member 62 stays in this position. Only by applying a greater external force can the toggle member 62 cross the convex rib and switch to another state. The number of the convex rib is at least one, which can cooperate with the two grooves, so that the toggle member 62 can stay in the two state positions of the chamber 4 far away from the regulating unit 5 and close to the regulating unit 5. Of course, in other embodiments, it can also be other limiting structures in the prior art, which are not specifically limited.

[0050] Of course, the driving assembly 6 can also be other structures, such as the driving assembly 6 includes a driving wheel, an external thread segment extending vertically from the center of the driving wheel, and an internal thread portion arranged in the chamber 4. The driving wheel is rotatably connected to the water squeezing frame 1, and part of the driving wheel extends out of the surface of the water squeezing frame 1. A flat plate is connected to the chamber 4, and the flat plate forms a notch portion supporting the external thread segment, and the inner wall of the notch portion forms an internal thread portion. Applying external force to rotate the driving wheel, the external thread segment and the internal thread portion cooperate to drive the chamber 4 to move.

[0051] Of course, the above-mentioned movable track 63 can also be opened on the control unit 5, so as to drive the control unit 5 to extend or retract the water squeezing rack 1. Here, the control unit 5 enters a working state when extending the water squeezing rack 1, and enters a waiting state when retracting the water squeezing rack 1. The specific structure is similar to the above and will not be repeated here.

[0052] The above-mentioned moving track 63 can also be provided on both the cavity 4 and the regulating unit 5, so as to drive the regulating unit 5 and the cavity 4 to extend or retract the water squeezing rack 1 together. The specific structure is similar to the above and will not be repeated.

[0053] Taking the example of the driving component 6 driving the cavity 4 to move relative to the squeezing frame 1 to move closer to or away from the regulating unit 5, during use, when the regulating unit 5 and the cavity 4 are close to each other, and both are also close to the squeezing channel 11, when the flat mop 2 is inserted into the squeezing channel 11 and pulled up and down, the wiping material of the flat mop 2 drives the rotating body 51 to rotate, and then drives the eccentric wheel 52 to rotate and contact the deformable member 53, so that the cleaning body outlet 41 is opened under the condition that the air pressure in the cavity 4 changes, and the cleaning body is transported to the wiping material, and the wiping material is deeply cleaned. After the wiping material adheres to the cleaning body, it is pulled and pushed by the extruding member 3, and the cleaning body is foamed and filled. The deep cleaning effect of the wiping object is better; after the deep cleaning is completed, an external force is applied to the toggle member 62 to make the cavity 4 away from the regulating unit 5. Even if the flat mop 2 is inserted into the water squeezing channel 11 and pulled up and down, the wiping object of the flat mop 2 drives the rotating body 51 to rotate. Since the eccentric wheel 52 is far away from the deformable member 53, the eccentric wheel 52 cannot contact the deformable member 53 when rotating, that is, the cleaning body output port 41 is always in a closed state, so that the wiping object will not continue to adhere to the cleaning body. In the process of continuous pulling, pulling and pushing of the wiping object and the extruding member 3, the cleaning body on the wiping object is cleaned, and the rinsing process of the flat mop 3 is completed.

[0054] A hands-free flat mop comprises a flat mop body 22 with a wiping object, a mop rod 21 rotatably connected to the flat mop body 22, and a squeezing and cleaning mechanism of the above structure.

[0055] The above specific implementation modes are used to explain the present invention rather than to limit the present invention.
