DETAILED DESCRIPTION

[0046] 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.

[0047] like Figures 1 - 4 As shown, a flat mop cleaning and squeezing mechanism comprises a squeezing frame 1, a squeezing channel 2, an squeezing unit 4, and a chamber 5.

[0048] A water squeezing channel 2 is formed on the water squeezing rack 1 for the flat mop 3 to be inserted. The flat mop 3 can be pulled, pushed, or drawn relative to the water squeezing channel 2. In other words, the relative movement between the flat mop 3 and the water squeezing channel 2 realizes the up-and-down pulling, pushing, and squeezing of the flat mop 3. Of course, it can also be that the water squeezing rack 1 and the cavity 5 are combined to form the water squeezing channel 2, and no specific limitation is made.

[0049] A cavity 5 is arranged on the water squeezing rack 1 for storing a cleaning body, and the cleaning body is not limited either. It can be a liquid cleaning agent or a solid cleaning soap, such as soap, etc. The cavity 5 being arranged on the water squeezing rack 1 can be that the cavity 5 is set as an independent component within the water squeezing rack 1, that is, the cavity 5 is separately arranged from the water squeezing rack 1, or the cavity 5 and the water squeezing rack 1 are connected as a whole. This structure also corresponds to the formation of the water squeezing channel 2. That is, when the water squeezing rack 1 and the cavity 5 are relatively independent, the water squeezing channel 2 is formed by the water squeezing rack 1, and when the water squeezing rack 1 and the cavity 5 are connected together, the water squeezing channel 2 is formed by the combination of the water squeezing rack 1 and the cavity 5. Of course, the cavity 5 may not be a relatively independent component, and it can generally be understood as the partial structure corresponding to storing the cleaning body.

[0050] The squeezing member unit 4 at least includes a squeezing member 41, which faces the water squeezing channel 2 and is movably arranged. The cavity 5 and the squeezing member 41 are located on the same side. Taking the Figure 4 direction shown as an example, both the cavity 5 and the squeezing member 41 are located on the left side of the water squeezing channel 2. And the cavity 5 has an opening 51 facing the water squeezing channel 2. No specific limitation is made on the specific shape and structure of the opening 51, and its main function is to supply the output of the cleaning body.

[0051] The squeezing member 41 at least has a squeezing state close to the water squeezing channel 2 and a yielding state away from the water squeezing channel 2. In the squeezing state, the squeezing member 41 protrudes from the opening 51 of the cavity 5 and can abut against the flat mop 3, separating the cleaning body in the cavity 5 from the flat mop 3. That is, at this time, the cleaning body will not or hardly adhere to the wiping object of the flat mop 3. At this time, mainly the rinsing of the wiping object of the flat mop 3 is carried out to avoid a large amount of the cleaning body remaining on the wiping object when the flat mop 3 is mopping the floor. In the yielding state, the squeezing member 41 does not protrude from the opening 51 of the cavity 5, that is, the squeezing member 41 does not press the flat mop 3 in the direction away from the opening 51 of the cavity 5, and the cleaning body can contact the wiping object of the flat mop 3. Thus, at this time, mainly the deep cleaning after the wiping object of the flat mop 3 adheres to the cleaning body is carried out, making the cleaning effect of the flat mop 3 better. In the yielding state, the squeezing member 41 does not contact the flat mop 3, or, the squeezing member 41 also contacts the flat mop 3 at the same time, but does not press the flat mop 3 in the direction away from the opening 51 of the cavity 5. When the squeezing member 41 still contacts the flat mop 3, the wiping object adhering to the cleaning body and the squeezing member 41 are pulled, pushed, and squeezed up and down, and the foaming effect is better.

[0052] Specifically, as Figure 4 shown, when the extrusion member 41 is in the extrusion state, its end portion protrudes from the opening 51 of the cavity 5. In other words, the extrusion member 41 is closer to the water squeezing channel 2 than the opening 51 of the cavity 5. At this time, when the flat mop 3 is inserted into the water squeezing channel 2, the wiping material of the flat mop 3 can contact the extrusion member 41. However, since there is still a certain distance between the wiping material and the opening 51 of the cavity 5, the wiping material will not contact the cleaning body.

[0053] As Figure 11 shown, when the extrusion member 41 is in the retracted state, its end portion retracts to the left side of the opening 51 of the cavity 5. In other words, the opening 51 of the cavity 5 is closer to the water squeezing channel 2 than the extrusion member 41. At this time, when the flat mop 3 is inserted into the water squeezing channel 2, the wiping material of the flat mop 3 can contact the cleaning body. Of course, when the extrusion member 41 is in the retracted state, its end portion can also retract to be flush with the region of the opening 51 of the cavity 5. Thus, when the flat mop 3 is inserted into the water squeezing channel 2, the wiping material of the flat mop 3 contacts both the extrusion member 41 and the cleaning body at the same time.

[0054] In order to ensure that the flat mop 3 can be kept away from the opening 51 of the cavity 5 when the extrusion member 41 is in the extrusion state, and thus ensure that it does not contact the cleaning body, an avoidance space 11 is formed on the water squeezing frame 1. The avoidance space 11 is communicated with the water squeezing channel 2, and the avoidance space 11 is located on the side of the water squeezing channel 2 away from the cavity 5. When the extrusion member 41 enters the extrusion state, a part of the flat mop 3 enters the avoidance space 11, so that the distance between the flat mop 3 and the opening 51 of the cavity 5 increases.

[0055] The above-mentioned avoidance space 11 is located on the side of the water squeezing channel 2 away from the cavity 5. Specifically, as Figure 6 shown, the avoidance space 11 is located on the left side of the water squeezing channel 2, and the cavity 5 is located on the right side of the water squeezing channel 2. Again, as Figure 18 shown, the avoidance space 11 is located on the left side of the water squeezing channel 2, and the cavity 5 is located on the right side of the water squeezing channel 2.

[0056] The part of the above-mentioned flat mop 3 can be the flat mop body 32 or the mop rod 31, and there is no specific limitation. There is also no specific limitation on the specific position of the avoidance space 11.

[0057] As Figures 1 - 13 shown, at least a part of the water squeezing frame 1 corresponding to the water squeezing channel 2 extends obliquely away from the extrusion member 41, thereby forming the above-mentioned avoidance space 11. Specifically, the water squeezing frame 1 in the prior art usually extends vertically. As Figure 6 shown, the line L1 is a vertical line. However, in this embodiment, the part of the water squeezing frame 1 corresponding to the water squeezing channel 2 is inclined from top to bottom and from inside to outside, thereby forming the avoidance space 11.

[0058] When the squeezing member 41 is in the retracted state, the flat mop 3 can be pulled vertically up and down. When the squeezing member 41 is in the squeezing state, the flat mop 3 is squeezed by the squeezing member 41 towards the side where the avoidance space 11 is located. As Figure 4 shown, the mop rod 31 of the flat mop 3 can enter the avoidance space 11, so that the distance between the wiping object of the flat mop 3 and the opening 51 of the cavity 5 is increased, effectively ensuring that the wiping object does not contact the cleaning body, and can ensure the separation of the rinsing and deep cleaning of the flat mop.

[0059] As Figures 14 - 26 shown, an avoidance space 11 is formed on the side of the water squeezing frame 1 opposite to the squeezing member 41. An installation seat 13 is arranged in the avoidance space 11. The installation seat 13 protrudes towards the side where the squeezing member 41 is located, and an elastic reset member 12 is arranged in the installation seat 13. One end of the elastic reset member 12 abuts against the installation seat 13 of the water squeezing frame 1, and the other end extends towards the water squeezing channel 2, that is, towards the direction where the flat mop 3 is located, so as to abut against the flat mop body 32. In order to ensure the assembly stability of the elastic reset member 12 and also to provide sufficient elastic force, the number of the elastic reset members 12 is two or more, and a housing 14 is sleeved outside them. The housing 14 is movably connected to the installation seat 13.

[0060] When the squeezing member 41 is in the retracted state, the elastic reset member 12 extends and squeezes the housing 14 towards the direction where the flat mop body 32 is located. As Figure 23 、 25 shown, the housing 14 protrudes from the installation seat 13, that is, the housing 14 protrudes from the plane where L2 is located. The housing 14 squeezes the flat mop 3 towards the direction where the cavity 5 is located, so that the wiping object can effectively contact the cleaning body. When the squeezing member 41 is in the squeezing state, the flat mop 3 is squeezed by the squeezing member 41 towards the side where the avoidance space 11 is located. As Figure 17 、 18 shown, the housing 14 is squeezed and retracted into the installation seat 13.

[0061] In the above structure, there are no restrictions on the shape and specific spatial range of the avoidance space 11, as long as the distance between the flat mop body 32 and the opening 51 of the cavity 5 can be made larger. More precisely, the spatial difference generated by the position change of the housing 14 driven by the switching between the extended state and the contracted state of the elastic reset member 12 becomes the effective avoidance space 11.

[0062] Of course, in other implementation structures, the housing 14 can also be replaced with other structures. For example, a roller is arranged at one end of the elastic reset member 12 towards the direction where the flat mop 3 is located. The rotation axis of the roller abuts against the elastic reset member 12, so that the roller can protrude or retract relative to the installation seat 13.

[0063] As Figure 7, Figure 13 , Figure 25 As shown in Figure 13 , Figure 25 , etc., a reticular body 52 is provided in the cavity 5. The reticular body 52 at least partially wraps around the outer periphery of the cleaning body and is located at the opening 51 of the cavity 5. In this embodiment, the reticular body 52 is a foaming net, or the reticular body 52 is an elastic foaming net. The cleaning body is a solid cleaning soap, which is placed in the cavity 5 and its outer surface contacts the reticular body 52. At this time, the reticular body 52 can serve as the uneven structure for scraping the cleaning body, and is prone to adhering to the cleaning body and generating foam under the up-and-down pulling, pushing and squeezing of the wiping object of the flat mop 3.

[0064] In this embodiment, the reticular body 52 and the cavity 5 jointly wrap the cleaning body. In other embodiments, it can also be that the reticular body 52 entirely wraps the cleaning body and the two are placed in the cavity 5, or the reticular body 52 after entirely wrapping the cleaning body is connected in the cavity 5.

[0065] In order to drive the squeezer 41 to switch between the squeezing state and the yielding state, the squeezer unit 4 further includes a driving assembly 6. At least part of the driving assembly 6 moves so as to drive the squeezer 41 to switch between the squeezing state and the yielding state. This movement includes translational movement, and also includes rotational movement, or includes translational and rotational movements.

[0066] As Figure 2 , Figure 7 shown in Figure 2 , Figure 7 , etc., the driving assembly 6 at least includes a toggling transverse groove 61 opened on the water squeezing frame 1, a toggling member 62 movably connected to the water squeezing frame 1, and a moving track 63 opened on the squeezer 41. The toggling transverse groove 61 extends along the width direction of the water squeezing frame 1. A part of the toggling member 62 extends into the moving track 63, and a part of the toggling member 62 is located in the toggling transverse groove 61. In other words, the toggling member 62 extends into the moving track 63 after passing through the toggling transverse groove 61. Applying an external force to drive the toggling member 62 to move relative to the water squeezing frame 1 in the toggling transverse groove 61, the squeezer 41 can be made to extend out of or retract into the water squeezing frame 1, that is, to realize the switching between the squeezing state and the yielding state.

[0067] In this embodiment, the number of movable tracks 63 is two, and correspondingly, two toggle parts 621 that can extend into the movable track 63 are provided on the toggle member 62. The movable track 63 includes a chute 1 631, a chute 2 632 arranged parallel to the chute 1 631, and a transition chute 633 connecting the chute 1 631 and the chute 2 632. The transition chute 633 is arranged obliquely. Of course, the chute 1 631 and the chute 2 632 are not necessarily completely parallel, as long as they are not located in the same straight line. Specifically, the chute 1 631 extends along the width direction of the cavity 5, and the entire movable track 63 is a Z-shaped chute. Here, the Z-shaped chute refers to a shape trend close to the Z shape, which is not necessarily a standard Z shape, but can also be a mirror image shape of Z. The chute 1 and the chute 2, and the transition chute are not necessarily straight grooves, but can also be curved grooves. As long as the chute 1 631 and the chute 2 632 have a height difference and are connected to each other, the specific shape is not limited.

[0068] When external force is applied to make the toggle member 62 translate relative to the water squeezing frame 1 in the toggle transverse groove 61, due to the restriction of the toggle transverse groove 61, the two toggle parts 621 of the toggle member 62 can only translate laterally. Once it translates to a width exceeding the lateral width of the slide groove 1 631 or the slide groove 2 632, it will inevitably enter the transition slide groove 633. Since the toggle part 621 can only translate, the toggle part 621 moves against the transition slide groove 633, and the extrusion member 41 translates inward and outward under the drive of the toggle part 621.

[0069] In order to make the extrusion member 41 stay in the extrusion state stably, a positioning component for limiting the extrusion member 41 in the extrusion state or the yielding state is also included. 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 frame 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 two grooves, so that the toggle member 62 can stay when the extrusion member 41 is in the extrusion state or the yielding state. Of course, in other embodiments, it can also be other limiting structures in the prior art, which are not specifically limited.

[0070] In order to rotate at least part of the driving assembly 6 to drive the extrusion member 41 to switch between the extrusion state and the yield state, the driving assembly 6 may include a driving wheel, an external thread segment extending vertically from the center of the driving wheel, and an internal thread portion provided on the extrusion member 41. The driving wheel is rotatably connected to the water squeezing frame 1, and a portion of the driving wheel extends out of the surface of the water squeezing frame 1. A flat plate is connected to the extrusion member 41, 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 an external force to rotate the driving wheel, the external thread segment and the internal thread portion cooperate to drive the extrusion member 41 to move.

[0071] The extrusion unit 4 can be arranged on the water squeezing frame 1 or on the containing cavity 5, and the specific arrangement position is not limited.

[0072] When the cleaning body in the cavity 5 is a solid cleaning soap, the volume of the fixed cleaning soap becomes smaller after long-term use. In order to ensure that it can always effectively contact the mesh body 52, the squeezing mechanism may also include a pressing unit, which presses the solid cleaning soap toward the side where the opening 51 is located. Specifically, the pressing unit at least includes a pressing plate in contact with the cleaning body and an elastic member abutting against the pressing plate, and the other end of the elastic member abuts against the side wall of the cavity 5. As the volume of the cleaning body in the cavity 5 is deformed, the compressed elastic member continues to extend, and the cleaning body is pushed toward the mesh body 52 by the pressing plate.

[0073] A hands-free flat mop comprises a flat mop body 32 with a wiping object, a mop rod 31 rotatably connected to the flat mop body 32, and a cleaning and squeezing mechanism of the above structure.

[0074] During use, an external force can be applied to the toggle member 62 to make the squeezing member 41 enter a yielding state. At this time, when the flat mop 3 is inserted into the water squeezing channel 2 and pulled up and down, the wiping material of the flat mop 3 can fully adhere to the cleaning body and perform deep cleaning. Although the squeezing member 41 enters the yielding state, it can also contact with the wiping material, which is conducive to the foaming of the cleaning body during the friction between the two. After completing the deep cleaning, an external force is applied to the toggle member 62 to make the squeezing member 41 enter an squeezing state. At this time, the flat mop 3 partially enters the avoidance space 11 under the push of the squeezing member 41, so that the distance between the wiping material of the flat mop 3 and the open mouth 51 of the cavity 5 increases, so that the wiping material will hardly continue to adhere to the cleaning body. In the process of continuous pulling, pulling and pushing of the wiping material and the squeezing member 41, the cleaning body on the wiping material is cleaned, and the rinsing process of the flat mop 3 is completed.

[0075] The above specific implementation modes are used to explain the present invention rather than to limit the present invention. Any modification and change made to the present invention within the spirit of the present invention and the protection scope of the claims shall fall within the protection scope of the present invention.
