[0002] Chinese Patent CN217610928U discloses "A water squeezing frame and a mop", which includes a main body with a container part on it. A pressing pump head is connected to the container part, and a shaping frame is installed on the main body. The shaping frame is slidably installed on the main body. By sliding the shaping frame to squeeze the pressing pump head, the shaping frame is provided with flower outlet holes. Adding detergent raw materials into the container part, after the raw materials are pumped out, they pass through the flower outlet holes to realize embossing, and the detergent is extruded onto the ground in an embossed form, without the need to separately take a cleaner and spray it onto the ground, improving the cleaning efficiency. However, in the above structure, the pulling and cleaning of the mop and the cleaning of the mop with detergent are two relatively independent steps, and the combination of detergent cleaning and the pulling and cleaning process of the mop is not realized, and the cleaning effect of the mop needs to be further improved. Content of the Utility Model

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a squeezing mechanism for a flat mop and a hands-free flat mop, which combines the pulling and cleaning of the flat mop and the deep cleaning of the cleaning body into an integrated structure, facilitating the cleaning of the flat mop.

[0019] Further, the transmission roller has a tooth end blocking surface, and the locking member has a blocked surface card slot that can be engaged with the tooth end of the blocking surface.

Detailed implementation manners

[0043] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0044] Embodiment 1

[0045] As Figures 1-6 shown, a flat mop extrusion mechanism includes a water squeezing frame 1, a water squeezing channel 2, an extrusion member 7, a cavity 4, and a transfer unit 5.

[0046] The water squeezing channel 2 is for the flat mop 3 to be inserted. The water squeezing channel 2 is formed in the water squeezing frame 1, or the water squeezing frame 1 and the cavity 4 are combined to form the water squeezing channel 2, and there is no specific limitation. The flat mop 3 can be pulled, pushed, and drawn up and down inside the water squeezing channel 2. Or rather, 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.

[0047] The cavity 4 is arranged on the water squeezing frame 1 and is used to store the cleaning body, and there is no limitation on the cleaning body either. It can be a liquid cleaning agent or a solid cleaning soap such as soap, etc. In this embodiment, the cleaning body is a solid cleaning soap. The cavity 4 being arranged on the water squeezing frame 1 can be that the cavity 4 is arranged in the water squeezing frame 1 as an independent component, that is, the cavity 4 is separately arranged from the water squeezing frame 1, or the cavity 4 and the water squeezing frame 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 frame 1 and the cavity 4 are relatively independent, the water squeezing channel 2 is formed by the water squeezing frame 1, and when the water squeezing frame 1 and the cavity 4 are connected together, the water squeezing channel 11 is formed by the combination of the water squeezing frame 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.

[0048] The squeezing member 7 is located in the water squeezing channel 2. Specifically, it can be fixedly connected to the side of the water squeezing frame 1 facing the water squeezing channel 2, or it can be movably connected to the side of the water squeezing frame 1 facing the water squeezing channel 2; or, the squeezing member 7 is fixedly connected to the side of the cavity 4 facing the water squeezing channel 2, or it can be movably connected to the side of the cavity 4 facing the water squeezing channel 2. The squeezing member 7 is used to squeeze the wiping object of the flat mop 3 to realize the up-and-down pulling, pushing, and squeezing cleaning of the flat mop 3.

[0049] At least part of the transfer unit 5 can act on the flat mop 3 to cause at least part of the transfer unit 5 to move. The above-mentioned transfer unit 5 acting on the flat mop 3 can be that when the flat mop 3 is pulled, pushed, and drawn up and down in the water squeezing channel 2, it drives at least part of the transfer unit 5 to move, or when the flat mop 3 is pulled, pushed, and drawn up and down in the water squeezing channel 2, the flat mop 3 and at least part of the transfer unit 5 act together, and there is no specific limitation, so as to be used to transfer the cleaning body in the cavity 4 to the wiping object of the flat mop 3.

[0050] The transfer unit 5 at least has a movable part 51 that can rotate relative to the flat mop 3, and the movable part 51 has a concave-convex structure for obtaining the cleaning body. Such as Figure 4As shown, in this embodiment, the movable part 51 is a transmission roller 512, and transmission teeth 513 are evenly distributed on its outer wall. The transmission teeth 513 are the concave-convex structures for obtaining the cleaning body. The transmission roller 512 can rotate around the rotating shaft 514, so as to first transport the cleaning body in the cavity 4 into the space between adjacent transmission teeth 513, and then transport the cleaning body to the wiping object through the contact between the wiping object and the transmission teeth 513. By continuously rotating the transmission roller 512, the cleaning body in the cavity 4 is continuously transported to the wiping object. Of course, it cannot be excluded that the movable part 51 of the transfer unit 5 has no concave-convex structure, and the movable part 51 being a smooth plane can also achieve the transmission of the cleaning body. In addition, the concave-convex structure here also includes structures with relatively small concavities and convexities such as rough surfaces.

[0051] The transfer unit 5 has at least an active state and a locked state. In the active state, at least part of the transfer unit 5 moves, so as to transport the cleaning body in the cavity 4 to the wiping object, so that when the flat mop 3 is pulled and squeezed for cleaning in the water squeezing channel 2, the deep cleaning of the cleaning body is carried out at the same time, making the cleaning effect of the flat mop 3 better. In combination with the specific structure of this embodiment, the transmission roller 512 rotates around the rotating shaft 514, so that the transmission teeth 513 continuously scrape the cleaning body in the cavity 4 and rotate and transport it to the side of the water squeezing channel 2, so that the flat mop 3 can effectively adhere to the cleaning body between the transmission teeth 513 when being pulled and washed in the water squeezing channel 2.

[0052] In the locked state, the transfer unit 5 stops moving, so that the transport of the cleaning body in the cavity 4 to the wiping object stops. At this time, the flat mop 3 is pulled and squeezed for cleaning in the water squeezing channel 2 to complete the rinsing of the wiping object, avoiding that there are still a large amount of cleaning bodies remaining on the wiping object when the flat mop 3 is mopping the floor. In combination with the specific structure of this embodiment, the transmission roller 512 stops rotating. Even if the transmission teeth 513 facing the cavity 4 scrape the cleaning body, they cannot rotate and transport it to the side of the water squeezing channel 2. When the flat mop 3 is pulled in the water squeezing channel 2, it cannot adhere to the cleaning body.

[0053] For the switching of the transfer unit 5 between the active state and the locked state, the locking unit 6 is utilized. The locking unit 6 includes a driving part 61, a locking member 62 cooperating with the driving part 61, and an elastic reset member 63. The elastic reset member 63 abuts against the locking member 62, the water squeezing frame 1 or the cavity 4 respectively, and is used to press the locking member 62 towards the direction where the transfer unit 5 is located. Specifically, when the water squeezing frame 1 and the cavity 4 are combined to form the water squeezing channel 2, one end of the elastic reset member 63 abuts against the cavity 4, the driving part 61 can be connected to the cavity 4, and the driving part 61 can translate relative to the cavity 4; when the water squeezing frame 1 forms the water squeezing channel 2, one end of the elastic reset member 63 abuts against the cavity 4 or the water squeezing frame 1, the driving part 61 can be connected to the water squeezing frame 1, and the driving part 61 can translate relative to the water squeezing frame 1. The above-mentioned driving part 61 and the locking member 62 can be integrally connected or separately arranged.

[0054] When an external force is applied to the driving part 61, the locking member 62 can abut against the transfer unit 5, so that the transfer unit 5 is switched from the active state to the locked state. At this time, the elastic reset member 63 does not need to be provided. By applying an opposite external force to the driving part 61, the transfer unit 5 is switched from the locked state to the active state, that is, at this time the locking unit 6 includes the driving part 61 and the locking member 62, and the two can be integrally arranged. Of course, an elastic reset member can also be provided, and the force acting on the driving part 61 is the force that makes the locking member 62 away from the transfer unit 5.

[0055] Alternatively, when an external force is applied to the driving part 61, the locking member 62 can be separated from the state of abutting against the transfer unit 5, so that the transfer unit 5 is switched from the locked state to the active state. At this time, the elastic reset member 63 is provided. When the external force applied to the driving part 61 is stopped, under the action of the elastic reset member 63, the locking member 62 can abut against the transfer unit 5, that is, the transfer unit 5 is switched from the active state to the locked state.

[0056] As Figure 5 shown, for the structure where the locking member 62 abuts against the transfer unit 5, the transmission roller 512 has a blocking surface, and the locking member 62 has a blocked surface that can cooperate with the blocking surface. When the blocking surface and the blocked surface abut against each other, the transfer unit 5 enters the locked state. The specific structures of the blocking surface and the blocked surface can be a tooth end and a card slot. The transmission roller 512 has a tooth end 518, and the locking member 62 has a card slot 621 that can engage with the tooth end 518. When the tooth end 518 falls into the card slot 621, the transmission roller 512 cannot rotate around the rotating shaft 514, and the transfer unit 5 enters the locked state.

[0057] As Figure 6As shown, the positions of the tooth end and the slot can be interchanged, that is, the transmission roller 512 has a slot 621, and the locking member 62 has a tooth end 518 that can engage with the slot 621. When the tooth end 518 falls into the slot 621, the transmission roller 512 cannot rotate around the rotating shaft 514, and the transfer unit 5 enters a locked state.

[0058] like Figure 5 , Figure 6 As shown, the driving part 61 and the locking member 62 are separately arranged, the driving part 61 has a driving inclined surface 611, and the locking member 62 has an inclined action surface 622 that can abut against the driving inclined surface 611. Figure 6 Taking the direction shown as an example, the driving inclined surface 611 extends obliquely from the direction of the chamber 4 to the direction of the squeezing channel 2 and from the inside to the outside, and the inclined direction of the inclined action surface 622 is the same. Under the action of the elastic reset member 63, the lock member 62 presses in the direction of the transfer unit 5. When an external force is applied to the driving part 61, the driving part 61 translates to the side of the lock member 62. Under the action of the driving inclined surface 611 and the inclined action surface 622, the lock member 62 moves away from the transmission roller 512, that is, the lock member 62 moves away from the transfer unit 5, and the transfer unit 5 switches from the locked state to the active state. When an external force is applied to the driving part 61 in the opposite direction, the driving part 61 translates to the side away from the lock member 62. Under the restoring force of the elastic reset member 63, the lock member 62 moves toward the direction close to the transmission roller 512, that is, the lock member 62 approaches the transfer unit 5, and the transfer unit 5 switches from the active state to the locked state.

[0059] In this embodiment, the lock 62 is in a 7-shape, its slot 621 or tooth end 517 is located in the longitudinal part of the lock 62, its inclined action surface 622 is located in the transverse part of the lock 62, and part of the drive part 61 extends from the top side wall of the cavity 4 or the water squeezing rack 1. At this time, the spatial layout of the elastic reset member 63, the slot 621 or the tooth end 517 is more reasonable, the setting position of the drive part 61 is also convenient for operation, and the overall matching structure is more stable. Of course, the lock 62 can also include only the longitudinal part, which is not specifically limited.

[0060] The number of the transmission rollers 512 is one or two or more, and they are arranged in parallel along the pulling direction of the flat mop 3. In other words, two or more transmission rollers 512 are arranged up and down, and a plurality of transmission teeth 513 are evenly spaced around the outer wall of the transmission roller 512, so that the cleaning body can be evenly transmitted to the wiping object to avoid uneven distribution of the cleaning body. Of course, in other embodiments, the number of the transmission rollers 512 is not limited, and it can be one or more.

[0061] When the number of the transfer rollers 512 is two or more, at least two transfer rollers 512 are arranged in a staggered manner, and the transfer roller 512 close to the squeezing member 7 is closer to the water squeezing channel 2 than other transfer rollers 512. In other words, the transfer roller 512 close to the squeezing member 7 is arranged more towards the direction where the water squeezing channel 2 is located. Such an arrangement can increase the contact pressure between the wiper and the transfer roller 512, enabling the transfer roller 512 to rotate normally to transfer the cleaning body, and avoiding the situation where the transfer roller 512 close to the squeezing member 7 cannot rotate effectively due to the ineffective contact after the wiper is squeezed and deformed.

[0062] The transfer roller 512 can be rotatably connected to the cavity 4 and face the water squeezing channel 2, or can be rotatably connected to the water squeezing frame 1 and face the water squeezing channel 2. The installation position of the transfer roller 512 can be not limited, as long as it can rotate to achieve the transfer of the cleaning body.

[0063] When the cleaning body in the cavity 4 is a solid cleaning soap, after long-term use, the volume of the fixed cleaning soap becomes smaller. In order to enable it to always be in effective contact with the transfer unit 5, the squeezing mechanism can further include a pressing unit, which presses the solid cleaning soap towards the side where the transfer unit 5 is located. Specifically, the pressing unit at least includes a pressing plate in contact with the cleaning body and an elastic member against the pressing plate, and the other end of the elastic member abuts against the side wall of the cavity 4. As the volume of the cleaning body in the cavity 4 deforms, the compressed elastic member continuously elongates, and the cleaning body is pushed towards the transfer unit 5 by the pressing plate.

[0064] A hands-free flat mop includes a flat mop 3 with a wiper, a mop rod 31 rotatably connected to the flat mop 3, and the squeezing mechanism with the above structure.

[0065] During use, in the initial state, the transfer unit 5 is in a locked state, that is, the transmission roller 512 will not rotate. At this time, when the flat mop 3 is pulled up and down in the water squeezing channel 2 and pushed up and down relative to the squeezing member 7, the cleaning body will not be transferred to the wiping object of the flat mop 3; when it is necessary to use the cleaning body to clean the wiping object of the flat mop 3, an external force is applied to the driving part 61, so that the driving part 61 pushes the locking member 62 away from the transmission roller 512, and the transfer unit 5 switches from the locked state to the active state, that is, the transmission roller 512 can rotate. At this time, when the flat mop 3 is pulled up and down and pushed in the water squeezing channel 2, the wiping object not only squeezes with the squeezing member 7, but also contacts and interacts with the transmission roller 512, that is, the transmission roller 512 rotates around the rotating shaft 514 under the drive of the wiping object, so as to transfer the cleaning body in the cavity 4 to the wiping object, so that the wiping object is cleaned by the cleaning body while squeezing with the squeezing member 7; once it is necessary to switch back to the locked state of the transfer unit 5, the external force applied to the driving part 61 is stopped, and under the restoring force of the elastic reset member 63, the locking member 62 automatically moves towards the direction close to the transmission roller 512.

[0066] Embodiment 2

[0067] As Figure 7 shown, the difference between this embodiment and Embodiment 1 is that the movable part 51 of the transfer unit 5 is a transmission sphere 515, which is rollingly arranged in a circular hole 516, and the circular hole 516 is opened on the side wall of the cavity 4. The number of circular holes 516 is multiple, and the number of corresponding transmission spheres 515 is also multiple, which are arranged at intervals on the same plane of the cavity 4, so that each part of the wiping object can receive the cleaning body conveyed by the transmission spheres 515. Of course, the multiple transmission spheres 515 may not be located on the same plane, and there is no specific limitation. The outer wall of the transmission sphere 515 is distributed with grooves 517, and the grooves 517 are the concave-convex structures for obtaining the cleaning body. When the transmission sphere 515 rolls, the cleaning body in the cavity 4 can be transferred to the wiping object.

[0068] The locking unit 6 realizes the switching of the transfer unit 5 between the active state and the locked state. Specifically, the locking unit 6 may include locking rods corresponding to the transmission spheres 515 one by one. All the locking rods are connected to the same panel. By using an external force to move the panel with the locking rods towards the direction where the transmission spheres 515 are located, the locking rods are abutted against the transmission spheres 515, which can prevent the transmission spheres 515 from rotating in the circular holes 516. Applying a reverse external force to move the panel away from the transmission spheres 515 can separate the locking rods and the transmission spheres 515, and the transmission spheres 515 can rotate freely in the circular holes 516. Of course, the above external force can also be realized by an elastic reset member.

[0069] Other structures are the same as those in Embodiment 1 and will not be described in detail.

[0070] Embodiment III

[0071] As Figures 8-11 shown, the difference between this embodiment and Embodiment I is that the movable part 51 of the transfer unit 5 includes a transmission roller 512 and a scraping member 53, and both the transmission roller 512 and the scraping member 53 are arranged towards the water squeezing channel 2. Relatively speaking, the transmission roller 512 is located above the scraping member 53. When the flat mop 3 is pulled up and down for pushing and squeezing, it can drive the transmission roller 512 to rotate. While the transmission roller 512 is rotating, it drives the scraping member 53 to move, so that the scraping member 53 scrapes the cleaning body actively.

[0072] In this embodiment, the transmission roller 512 is rotatably connected to the water squeezing frame 1, and can contact the wiping object of the flat mop 3, and relatively rotate around its own rotating shaft 514 under the drive of the wiping object. An eccentric crank portion 54 is also connected to the transmission roller 512, that is, the center line of the crank portion 54 does not overlap with the center line of the rotating shaft 514.

[0073] The scraping member 53 for scraping the cleaning body is connected with a movable slot 55 for the crank portion 54 to extend into. The width of the movable slot 55 is approximately equivalent to the outer diameter of the crank portion 54, and the length of the movable slot 55 is greater than the outer diameter of the crank portion 54. When the transmission roller 512 rotates relative to the water squeezing frame 1, the crank portion 54 moves up and down in the movable slot 55, thereby driving the scraping member 53 to move up and down. At this time, it can also be said that the scraping member 53 rotates up and down. In this embodiment, the cleaning body is a solid cleaning soap, and the solid cleaning soap can be scraped during the upward or downward movement of the scraping member 53 and transmitted to the wiping object. In other words, at this time, the transmission roller 512 may not play the role of scraping the cleaning body, and of course, it does not exclude that the transmission roller 512 and the scraping member 53 play the role of scraping the cleaning body at the same time.

[0074] When the relative rotation of the transmission roller 512 drives the scraping member 53 to move up and down, the transfer unit 5 enters the active state. When the transmission roller 512 stops rotating relatively, it cannot drive the scraping member 53 to move up and down, and at this time, the transfer unit 5 enters the locked state.

[0075] In this embodiment, the specific structure of the locking unit 6 for realizing the switching of the transfer unit 5 between the active state and the locked state includes a driving portion 61 partially protruding from the surface of the extrusion mechanism, a locking member 62 connected to the driving portion 61, and a transmission tooth 513 and an avoidance portion 511 on the outer wall of the transmission roller 512. The locking member 62 can move relatively, so that it switches between two states of cooperating with the transmission tooth 513 and cooperating with the avoidance portion 511.

[0076] When an external force is applied to the driving part 61 so that the locking part 62 meshes with the transmission tooth 513, the transmission roller 512 stops rotating under the action of the locking part 62. At this time, the transmission roller 512 cannot drive the locking part 62 to move up and down, that is, there will be no mutual friction scraping action between the locking part 62 and the cleaning body, and the transfer unit 5 enters the locked state. The avoidance part 511 is of a groove structure. When an external force is applied in the reverse direction to the driving part 61 so that the locking part 62 disengages from the transmission tooth 513 and the locking part 62 enters the relative position corresponding to the avoidance part 511, the meshing teeth on the locking part 62 are within the avoidance part 511, and it will not act on the transmission roller 512, and the transmission roller 512 can rotate freely. Thus, the scraping part 53 can move up and down (here, up and down is illustrated by the Figure 9 direction shown) under the drive of the transmission roller 512 to scrape the cleaning body, and the transfer unit 5 enters the active state.

[0077] Another function of the transmission tooth 513 is to better transmit the acting force of the wiping object to the transmission roller 512, so that the transmission roller 512 can rotate around its own rotating shaft 514. In this structure, both the transmission roller 512 and the scraping part 53 can be understood as the movable part 51 of the transfer unit 5. The scraping part 53 can be understood as the concave-convex structure on the movable part 51, or both the scraping part 53 and the transmission tooth 513 can be understood as the concave-convex structure on the movable part 51. Specifically, in this embodiment, the scraping part 53 can be a grid-like structure, and the cleaning body is transmitted from the gap to the wiping object.

[0078] Other structures are the same as those in the first embodiment and will not be described in detail.

[0079] The above specific implementation manners are used to explain and illustrate the present invention, rather than to limit the present invention. Any modification and change made to the present invention within the spirit and protection scope of the claims of the present invention fall within the protection scope of the present invention.
