Description

Technical Field

[0001] This utility model belongs to the field of cleaning equipment technology, and in particular relates to a flat mop squeezing device and a hands-free flat mop. Background Technology

[0002] Chinese patent CN217610928U discloses a "Wringer and Mop," which includes a main body with a container section connected to a pump head. A shaping frame is mounted on the main body and is slidably installed thereon. The pump head is squeezed by sliding the shaping frame, which has a perforation hole. Detergent is added to the container section, and after being pumped out, it passes through the perforation hole to create a perforated pattern, squeezing the detergent onto the floor in a perforated form. This eliminates the need for additional cleaning agent spraying, improving cleaning efficiency. However, in this structure, the mop pulling and cleaning with detergent are two relatively independent steps; the detergent cleaning process is not integrated into the mop pulling process, leaving the cleaning effect of the mop needing further improvement. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a flat mop squeezing device and a hands-free flat mop, which combines the pull-out cleaning of the flat mop and the deep cleaning of the cleaning body into an integrated structure, making it convenient to clean the flat mop.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a flat mop squeezing device, comprising:

[0005] The wringer has a wringing channel for inserting a flat mop, which can be pulled up and down relative to the wringing channel.

[0006] An extrusion member, disposed on the wringer and facing the wringer channel, is used to extrude the wiping material from the flat mop.

[0007] The cavity, located on the dewatering rack, is used to store the cleaning agent;

[0008] The transmission unit, at least partially oriented toward the wringing channel, has a working state for transmitting cleaning material to the flat mop wiping material and a waiting state for stopping the transmission of cleaning material to the flat mop wiping material; in the working state, the cleaning material abuts against the transmission unit, the flat mop wiping material contacts at least a portion of the transmission unit, and drives the transmission unit to move, so that the transmission unit acquires the cleaning material in the cavity and transmits it to the flat mop wiping material.

[0009] Furthermore,

[0010] The relative positions of the cleaning body and the transmission unit within the cavity change, so that the transmission unit switches between a working state and a waiting state.

[0011] or,

[0012] The transmission unit and the cavity as a whole move relative to the dewatering frame so that the transmission unit switches between working state and waiting state;

[0013] or,

[0014] The cavity moves relative to the dewatering frame so that the transmission unit switches between a working state and a waiting state;

[0015] or,

[0016] The blocking unit moves between the transmission unit and the cleaning body to switch the transmission unit between an operating state and a waiting state.

[0017] or,

[0018] The blocking unit moves between the transmission unit and the squeezing channel to switch the transmission unit between an operating state and a waiting state.

[0019] or,

[0020] The blocking unit moves between the transmission unit and the extruder to switch the transmission unit between an operating state and a waiting state.

[0021] Furthermore, it also includes a positioning component for limiting the transmission unit to an operating state or a waiting state.

[0022] Furthermore, the transmission unit includes a first part and a second part, the first part being disposed toward the squeezing channel, and the cleaning body within the cavity being movable relative to the squeezing frame under the drive of the second part, so that the cleaning body moves away from the first part of the transmission unit.

[0023] Furthermore, the second part includes a rotatable lifting member one and a lifting member two, a movable member one connected to the lifting member one, a movable member two connected to the lifting member two, and a force-applying member. A sliding column and a track groove are provided between the movable member one and the movable member two. The wringer is formed with an arc-shaped slide rail. The force-applying member extends from the arc-shaped slide rail and is driven by an external force to move within the arc-shaped slide rail. The sliding column moves within the track groove so that the lifting paddles on the lifting member one and the lifting member two cooperate to lift the cleaning body away from the first part.

[0024] Furthermore, the positioning component is a protrusion formed at both ends of the arc-shaped slide rail.

[0025] Furthermore, the blocking unit includes a baffle and a driving part, the driving part extending from the slot of the water squeezing frame, and the positioning component being a positioning protrusion formed at both ends of the inner sidewall of the slot.

[0026] Furthermore, the cavity and / or the squeezing frame are provided with an elastic deformation part to achieve a tight fit between the two. When an external force is applied to control the deformation of the elastic deformation part, the cavity can move relative to the squeezing frame so that it moves away from or closer to the squeezing channel.

[0027] Furthermore, the positioning component includes a snap-fit ​​portion formed on the elastically deformable portion and a locking groove provided in the desqueezing frame. When an external force is applied to control the deformation of the elastically deformable portion, the snap-fit ​​portion can fall into the locking groove to form a limiting fit, or the snap-fit ​​portion can disengage from the locking groove.

[0028] Furthermore, the positioning component also includes an anti-detachment boss disposed in the cavity and a stroke groove disposed in the wringer. The anti-detachment boss can move within the stroke groove to limit the movement stroke of the cavity relative to the wringer.

[0029] Furthermore, the transmission unit has at least a movable part that can rotate or move relative to the flat mop, the movable part having a concave-convex structure for acquiring the cleaning body.

[0030] Furthermore, the movable part is a transfer roller with transfer teeth distributed on its outer wall, which rotates around the axis to transfer the cleaning body in the cavity to the wiping object; or, the movable part is a transfer ball that rolls inside a circular hole with grooves distributed on its outer wall, which rolls to transfer the cleaning body in the cavity to the wiping object.

[0031] Furthermore, the number of the transmission rollers is one or two or more, and they can be arranged parallel to the pulling direction of the flat mop; the number of the transmission balls is multiple.

[0032] Furthermore, the cleaning body is a solid cleaning soap, and the squeezing device also includes a pressing unit, which presses the solid cleaning soap toward the side where the transmission unit is located; the pressing unit includes at least a pressure plate in contact with the cleaning body and an elastic member abutting against the pressure plate.

[0033] This utility model also discloses a hands-free flat mop, including a flat mop with a wiping agent, a mop handle rotatably connected to the flat mop, and the aforementioned squeezing device.

The relative position change of the drive transmission unit and the movement of the blocking unit do not require a separate drive mechanism, simplifying the structure; 6) The transmission unit includes a rotatable transmission roller with transmission teeth evenly distributed on its outer circumference, ensuring that the cleaning body is evenly distributed to the wiping object, avoiding excessive cleaning body in some areas that cannot be rinsed clean, and also avoiding insufficient cleaning body in some areas that cannot be effectively cleaned; 7) The positioning component ensures that the transmission unit remains stably in the working or waiting state, and will not deviate randomly during use; 8) The holding unit ensures that the transmission unit can still contact the cleaning body and effectively transmit it to the wiping object after long-term use; 9) The cleaning body can achieve a good stain removal effect on the flat mop and remove odors. In addition, the cleaning body can increase the lubrication of the surface of the wiping object during washing, extending the service life of the wiping object. Attached Figure Description

Detailed Implementation

[0050] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort should fall within the scope of protection of the present invention.

[0051] like Figure 1 As shown, the flat mop squeezing device includes a wringer 1, a squeezing component 2, a cavity 3, and a transmission unit 4.

[0052] The wringer 1 has a wringing channel 11 for inserting the flat mop 9. Alternatively, the wringer 1 and the cavity 3 can be combined to form the wringing channel 11. No specific limitation is made. The flat mop 9 can be pulled up and down and pushed inside the wringing channel 11. In other words, the flat mop 9 and the wringing channel 11 move relative to each other to achieve the up and down pulling and pushing of the flat mop 9.

[0053] The location of the extrusion component 2 is not limited at the moment. It is used to extrude the wiping material of the flat mop 9 and to clean the flat mop 9 by pulling and pushing it up and down. Specifically, it can be used to rinse the flat mop 9 or to rub and foam the wiping material after obtaining the cleaning body 31.

[0054] The cavity 3 is located on the wringer 1 and is used to store the cleaning agent. The cleaning agent is not limited; it can be a liquid detergent or a solid cleaning soap, such as regular soap. The cavity 3 can be a separate component within the wringer 1, or it can be integrated with the wringer 1. This structure also corresponds to the formation of the wringing channel 11. When the wringer 1 and the cavity 3 are relatively independent, the wringing channel 11 is formed by the wringer 1. When the wringer 1 and the cavity 3 are connected, the wringing channel 11 is formed by the wringer 1. Of course, the cavity 3 does not have to be a relatively independent component; it can be broadly understood as part of the structure corresponding to the storage of the cleaning agent.

[0055] At least a portion of the transmission unit 4 is disposed toward the wringing channel 11, thereby enabling it to interact with the flat mop 9. The interaction between the transmission unit 4 and the flat mop 9 can be either driven by the flat mop 9 pulling and pushing up and down within the wringing channel 11, or the two can work together when the flat mop 9 pulls and pushes up and down within the wringing channel 11. The specific interaction is not limited. This is used to transfer the cleaning material in the cavity 3 to the wiping material of the flat mop 9. The transmission unit 4 has at least a movable part 40 that can rotate relative to the flat mop 9. The movable part 40 has a concave-convex structure for acquiring the cleaning material.

[0056] like Figure 2 As shown, in this embodiment, the movable part 40 is a transfer roller 41, whose outer wall is evenly distributed with transfer teeth 411. These transfer teeth 411 are the uneven structure used to acquire the cleaning body. The transfer roller 41 can rotate around the rotating shaft 42, thereby transferring the cleaning body in the cavity 3 first into the space between adjacent transfer teeth 411, and then transferring the cleaning body to the wiping object through the contact between the wiping object and the transfer teeth 411. By continuously rotating the transfer roller 41, the cleaning body in the cavity 3 is continuously transported to the wiping object. Of course, it is not excluded that the transfer part of the transfer unit 4 does not have an uneven structure; the transfer part can also achieve the transfer of the cleaning body by being a smooth plane. In addition, the uneven structure here also includes structures with small unevenness, such as rough surfaces.

[0057] like Figure 14 As shown, the movable part 40 of the transmission unit 4 can also be a transmission ball 43, which is rolled within a circular hole 431, which is formed on the side wall of the cavity 3. There are multiple circular holes 431, and correspondingly multiple transmission balls 43, which are spaced apart on the same plane of the cavity 3, so that all parts of the wiping object can receive the cleaning material transported by the transmission balls 43. Of course, the multiple transmission balls 43 may not be located on the same plane; there is no specific limitation. The outer wall of the transmission ball 43 is distributed with grooves 432, which are the concave-convex structures for acquiring the cleaning material. When the transmission ball 43 rolls, it can transport the cleaning material in the cavity 3 to the wiping object.

[0058] The transmission unit 4 has at least a working state and a waiting state. In the working state, at least a portion of the transmission unit 4 contacts the cleaning material of the flat mop 9, thereby transmitting the cleaning material in the cavity 3 to the cleaning material. This allows the flat mop 9 to perform deep cleaning of the cleaning material while being pulled out and squeezed in the wringing channel 11, resulting in a better cleaning effect. In the waiting state, the transmission unit 4 stops transmitting the cleaning material to the cleaning material. At this time, the flat mop 9 is pulled out and squeezed in the wringing channel 11 to complete the rinsing of the cleaning material, thus preventing a large amount of cleaning material from remaining on the cleaning material when the flat mop 9 is mopping.

[0059] The switching between the working state and the waiting state of the transmission unit 4 is caused by the change in the relative position of the cleaning body and the transmission unit 4 within the cavity 3.

[0060] like Figures 2-5As shown, the transmission unit 4 includes a first part 44 and a second part 45. The first part 44 is disposed facing the squeezing channel 11, and the second part 45 is opposite to the first part 44. The two are located on opposite sides of the cleaning body. The cleaning body in the cavity 3 can move relative to the squeezing frame 1 under the drive of the second part 45, so that the cleaning body moves away from the first part 44 of the transmission unit 4. Specifically, the cleaning body can move outward away from the transmission unit 4 under the action of the second part 45.

[0061] The structure of the first part 44 is a transmission roller structure, which is rotatably connected to the dewatering frame 1 or the cavity 3, and the specific details will not be described further. In this embodiment, the dewatering frame 1 and the cavity 3 are connected together, that is to say, the cavity 3 is not an independent component, it can be generally understood as the part of the structure corresponding to the storage of the cleaning body, and there is no clear dividing line between it and the dewatering frame 1.

[0062] The second part 45 includes a lifting member 451 and a lifting member 452 rotatably connected to the cavity 3 or the squeezing frame 1, a movable member 453 connected to the lifting member 451, a movable member 454 connected to the lifting member 452, and a force-applying member 455. The lifting members 451 and 452 extend the entire width of the extrusion device and are generally rod-shaped. Crucially, both the lifting members 451 and 452 are equipped with lifting levers 450.

[0063] There are at least two movable parts 453, located at both ends of the lifting part 451 and connected at an angle to it. Similarly, there are at least two movable parts 454, located at both ends of the lifting part 452 and connected at an angle to it. A vertical sliding column 456 is provided on the movable part 453, and a track groove 457 is provided on the movable part 454. After assembly, the sliding column 456 falls into the track groove 457. The force-applying component 455 is integrally connected to the sliding column 456, and both are located on either side of the movable part 453.

[0064] like Figure 4As shown, the wringer 11 has an arc-shaped slide rail 458. Of course, the arc-shaped slide rail 458 can also be set on the cavity 3, and there is no specific limitation. The force-applying member 455 extends from the arc-shaped slide rail 458. When an external force is applied to make the force-applying member 455 move relative to the wringer 11 in the arc-shaped slide rail 458, the lifting member 1 451 rotates, which drives the lifting paddle 450 to rotate. At this time, the sliding column 456 moves in the track groove 457, and the lifting paddle 450 on the lifting member 2 452 also rotates. Therefore, the lifting member 1 451 and the lifting paddle 450 on the lifting member 2 452 cooperate to lift the cleaning body away from the first part 44. At this time, the transmission unit 4 enters the waiting state. The transmission unit 4 switches from the waiting state to the working state through the pressing unit 8 that abuts against the cleaning body 31, which presses the cleaning body 31 in the direction of the transmission unit 4.

[0065] In order to securely limit the transmission unit 4 to the working state or the waiting state, a positioning component 7 is also provided. In the above structure, the positioning component 7 is a protrusion 71 formed at both ends of the arc-shaped slide rail 458. Once the force-applying member 455 falls between the protrusion 71 and the end face of the arc-shaped slide rail 458, it is securely limited and can only be released from the limit by applying a greater external force.

[0066] The switching between the working state and the waiting state of the transmission unit 4 can also be achieved by moving the transmission unit 4 and the cavity 3 together relative to the dewatering frame 1.

[0067] like Figures 9-13 As shown, the transmission unit 4 is disposed on the cavity 3. The cavity 3 is provided with an elastic deformation part 32 that can be tightly fitted with the wringer 1. When an external force is applied to control the deformation of the elastic deformation part 32, the cavity 3 can move relative to the wringer 1, thereby causing the cavity 3 to move away from or towards the wringer channel 11 along with the transmission unit 4. Of course, the transmission unit 4 and the cavity 3 can also be disposed separately. In this case, the transmission unit 4 and the wringer 1 are relatively fixed, and the cavity 3 moves independently relative to the wringer 1, thereby causing the cavity 3 to move away from or towards the wringer channel 11 while also moving away from or towards the transmission unit 4. When the cavity 3 moves away from the transmission unit 4, the transmission unit 4 is in a waiting state, and even if it can rotate, it cannot obtain the cleaned body. When the cavity 3 moves towards the transmission unit 4, the transmission unit 4 is in a working state.

[0068] Specifically, the elastic deformation part 32 is a structure that extends outward relative to the sidewall of the cavity 3 and has a restorative elastic force. When squeezed by the middle sidewall 13 and the inner sidewall of the wringer 1, it can achieve a stable assembly. Once an external force is applied to press the elastic deformation part 32 inward, the cavity 3 can break free from the constraints of the middle sidewall 13 and the inner sidewall of the wringer 1 and move relative to it. The elastic deformation part 32 is disposed on the upper and lower sides of the cavity 3. Of course, in other embodiments, the elastic deformation part 32 can also be disposed on the left and right sides of the cavity 3. The elastic deformation part 32 can also be disposed on the wringer 1, or the elastic deformation part 32 can be disposed on both the wringer 1 and the cavity 3, as long as a tight fit between the cavity 3 and the wringer 1 is achieved; no specific limitation is imposed.

[0069] The positioning component 7 includes a snap-fit ​​part 73 disposed in the elastic deformation part 32 and a locking groove 74 disposed in the dewatering frame 1. When the snap-fit ​​part 73 falls into the locking groove 74, the two form a limiting engagement, and subsequently the cavity 3 and the dewatering frame 1 form a limiting engagement, and the cavity 3 is stably limited to prevent it from shifting arbitrarily relative to the dewatering frame 1. When an external force is applied to control the elastic deformation part 32 to deform and pull the cavity 3 outward, the snap-fit ​​part 73 can disengage from the locking groove 74, the cavity 3 moves away from the dewatering channel 11, and the transmission unit 4 enters a waiting state.

[0070] To prevent the cavity 3 from completely detaching from the wringer 1, the positioning assembly 7 also includes an anti-detachment protrusion 75 disposed in the cavity 3 and a travel groove 76 disposed in the middle side wall 13 of the wringer 1. The travel groove 76 is disposed adjacent to the locking groove 74. The anti-detachment protrusion 75 can move within the travel groove 76. Once the cavity 3 moves relative to the wringer 1 until the anti-detachment protrusion 75 abuts against the end face of the travel groove 76, the cavity 3 cannot continue to move outward, thus limiting the travel stroke of the cavity 3 relative to the wringer 1. Similarly, preventing the cavity 3 from moving excessively inward relative to the wringer 1 is achieved by the anti-detachment protrusion 75 abutting against the inner end face of the travel groove 76.

[0071] To facilitate the application of external force to compress the elastic deformation part 32, an outwardly bent flange 321 can be provided at its end. This flange 321 is arranged vertically parallel to the locking part 73 and the anti-detachment boss 75. Figure 12 As shown.

[0072] The switching between the working state and the waiting state of the transmission unit 4 can also be achieved by the movement of the blocking unit 5 between the transmission unit 4 and the cleaning body. Alternatively, it can be achieved by the movement of the blocking unit 5 between the transmission unit 4 and the squeezing channel 11. Or, it can be achieved by the movement of the blocking unit 5 between the transmission unit 4 and the squeezing member 2.

[0073] like Figures 6-8As shown, the squeezing element 2 and the cavity 3 are fixed relative to each other on the wringing frame 1. The transmission unit 4 is located on the side of the cavity 3 facing the wringing channel 11, and the squeezing element 2 also faces the wringing channel 11. The squeezing element 2 and the transmission unit 4 are arranged vertically, so they can simultaneously squeeze the wiping material from the flat mop 9. Relatively speaking, the squeezing element 2 is slightly closer to the wringing channel 11, and the transmission unit 4 is slightly farther away from the wringing channel 11. The wringing frame 1 is also provided with a blocking unit 5. The blocking unit 5 can pass through the squeezing element 2 and move to the opposite side of the transmission unit 4. In other words, the blocking unit 5 can pass through the squeezing element 2 and move between the wiping material and the transmission unit 4, thereby isolating the transmission unit 4 from the wiping material. Of course, the blocking unit 5 can also not pass through the squeezing element 2, but can pass through the squeezing element 2 and the transmission unit 4, or the blocking unit 5 can move to be located between the wringing channel 11 and the transmission unit 4, or the blocking unit 5 can move between the cleaning body and the transmission unit 4. There are no specific restrictions. The ultimate purpose is to isolate the transmission unit 4 from the wiping material.

[0074] Alternatively, the extruder 2 can be fixedly connected to the wringer 1, and the blocking unit 5 can move from below the extruder 2 to the opposite side of the transmission unit 4, thus isolating the transmission unit 4 from the wiping material. Alternatively, the extruder 2 can be fixedly connected to the wringer 1, with a gap between the extruder 2 and the wringer 1, allowing the blocking unit 5 to move through this gap to the opposite side of the transmission unit 4. In the above structures, the blocking unit 5 moves from top to bottom to the opposite side of the transmission unit 4. In other embodiments, the blocking unit 5 can move from the side of the transmission unit 4 to directly opposite it; there are no specific limitations. The blocking unit 5 can be a plate-like structure capable of certain deformation but also possessing a certain rigidity; there are no specific limitations.

[0075] Of course, the aforementioned extrusion component 2 can also be movably connected to the dewatering frame 1, and there are no specific restrictions.

[0076] During use, when only the squeezing part 2 is needed, the blocking unit 5 is moved to the opposite side of the transmission unit 4 so that the cleaning material in the cavity 3 will not be transmitted to the wiping material of the flat mop 9 through the transmission unit 4. At this time, the transmission unit 4 enters the waiting state. When the cleaning material is needed, the blocking unit 5 is moved back so that both the transmission unit 4 and the squeezing part 2 can come into contact with the wiping material of the flat mop 9. At this time, the transmission unit 4 enters the working state.

[0077] The blocking unit 5 includes a baffle 51 and a drive unit 52. The moving part is mainly the baffle 51. The drive unit 52 extends out from the slot 12 of the squeezing frame 1. The positioning component 7 is a positioning protrusion 72 formed on both ends of the inner sidewall of the slot 12. Once the drive unit 52 falls between the positioning protrusion 72 and the end face of the slot 12, it is firmly limited and can only be released from the limit by applying a greater external force.

[0078] When the cleaning agent in the cavity 3 is a solid cleaning soap, its volume decreases after prolonged use. To ensure it remains in effective contact with the transmission unit 4, the extrusion device may also include a pressing unit 8, which presses the solid cleaning soap against the side where the transmission unit 4 is located. Specifically, the pressing unit 9 includes at least a pressure plate 81 that contacts the cleaning agent and an elastic member that abuts against the pressure plate 81. The other end of the elastic member abuts against the side wall of the cavity 3. As the volume of the cleaning agent in the cavity 3 deforms, the compressed elastic member (not shown in the figure) continuously elongates, using the pressure plate 81 to push the cleaning agent towards the transmission unit 4.

[0079] like Figure 9 As shown, a hands-free flat mop includes a flat mop 9 with a wiping agent, a mop handle 91 rotatably connected to the flat mop 9, and a squeezing device with the above-described structure.

[0080] The above specific embodiments are used to explain and illustrate the present utility model, and are not intended to limit the present utility model. Any modifications and changes made to the present utility model within the spirit and scope of the claims shall fall within the protection scope of the present utility model.
