Description

Technical Field

[0001] The present invention relates to the technical field of cleaning tools, and particularly relates to a water squeezing component, a water squeezing device and a cleaning device for a flat mop. Background Art

[0002] A mop is a commonly used cleaning tool and is widely used in daily life. Currently, commonly used mops are usually divided into two types: flat mops and rotary mops. Among them, rotary mops are usually used in conjunction with a cleaning bucket, and the cleaning bucket can utilize the centrifugal force to clean and wring out the rotary mop, avoiding hand washing. Compared with rotary mops, flat mops have a larger cleaning area, are more evenly stressed during use, have a better cleaning effect, and are more widely used in daily life. Existing flat mops usually include a mop head and a mop rod. The mop head includes a back plate and a wiping part fixed to the back plate. The back plate is connected to one end of the mop rod. According to the different materials and properties of the wiping part in the mop head, the mop heads of existing flat mops can usually be divided into: cotton swab mop heads, fiber mop heads, and cotton mop heads. Among them, a flat mop provided with a cotton swab mop head is usually simply referred to as a cotton swab flat mop. Because cotton swabs have strong water absorption, it is not necessary to sweep the floor before mopping. Static electricity is formed through air convection and friction, which can absorb dust, sand, and hair without damaging the ground, and is increasingly favored by consumers.

[0003] Due to structural reasons, flat mops are usually not convenient to clean by rotation. Therefore, existing cleaning devices for flat mops usually are provided with a water squeezing device. For example, a squeezing flat mop cleaning tool disclosed in Chinese Patent CN 107456180A and a flat mop cleaning device disclosed in Chinese Patent CN 110251014A are both provided with a water squeezing device. In actual use, the user can utilize the water squeezing device in the cleaning device and achieve the water squeezing operation by pulling up and down, and can smoothly drain the water in the mop head to achieve the purpose of cleaning the mop head.

[0004] Existing water squeezing devices usually include a water squeezing frame and a water squeezing component. Among them, the water squeezing frame is configured with a slot (or called a communication port) for inserting the mop head. The slot is usually a T-shaped structure, and a roller is usually arranged on one side of the slot. The water squeezing component is usually arranged on the other side of the slot and corresponds to the roller. The water squeezing component and the roller jointly form a squeezing mechanism for squeezing the mop head. After the mop head is vertically inserted into the slot, the back plate of the mop head contacts the roller, and the wiping part of the mop head contacts the water squeezing component and squeezes each other, so that the wiping part and the water squeezing component move relative to each other during the process of pulling up and down to achieve the purpose of squeezing water.

[0005] In a conventional squeezing device, a squeezing component is usually a scraper (or a stroking plate). However, in actual use, the scraper is likely to damage the mop head, especially for a collodion flat mop. In the process of the collodion mop head and the scraper being squeezed and moved relative to each other, the collodion mop head is very likely to be scratched by the scraper, resulting in the existing scraper being unsuitable for the collodion flat mop. In some novel squeezing devices disclosed in the prior art, such as Chinese patent CN210493978, U discloses a cleaning tool for a rubber cotton mop, etc., in which a squeezing component usually adopts a squeezing wheel. In actual use, when the mop head is vertically inserted into the stroking opening and moves up and down relative to the stroking opening, the squeezing wheel can not only squeeze the mop head to achieve the purpose of squeezing water, but also rotate with the movement of the mop head to achieve rolling contact. Therefore, the squeezing process will not damage the mop head. It is suitable for rubber cotton flat mops and can solve the problem of non-damage squeezing water of rubber cotton flat mops. However, in the existing squeezing wheels, the contact area is usually increased to improve the squeezing effect. Therefore, the outer surface of the existing squeezing wheel is usually a closed structure to achieve continuous contact and squeezing with the mop head. However, in the process of the mop head of the flat mop moving downward and cooperating with the squeezing wheel to squeeze water, the squeezed water will accumulate in the groove formed above the contact position between the squeezing wheel and the mop head, such as Figure 1 As shown, it cannot be quickly separated from the mop head, which is very unfavorable for improving the water squeezing efficiency. Moreover, in the subsequent water squeezing process, if the mop head continues to move downward relative to the squeezing wheel, due to the effect of gravity, the squeezed water will automatically flow downward along the mop head under the effect of gravity, and will flow back again to the mop head area that has passed through the squeezing wheel and has completed the water squeezing, thereby further reducing the water squeezing efficiency; if the mop head starts to move in the opposite direction (i.e., move upward), at this time, the mop head moves upward relative to the water in the groove, which will accelerate the absorption of the squeezed water in the groove by the mop head, thereby greatly reducing the water squeezing efficiency. Therefore, when the existing squeezing wheel cooperates with the flat mop to squeeze water, there is always a problem that the squeezed water is easy to flow back to the mop head, resulting in low water squeezing efficiency, repeated squeezing, and incomplete squeezing, which needs to be solved urgently. Summary of the invention

[0006] In the existing water squeezing device, the outer surface of the squeezing wheel is a closed structure, which causes a relatively closed groove to form above the contact position between the mop head of the flat mop and the squeezing wheel. During the process of the mop head of the flat mop moving downward and squeezing water in cooperation with the squeezing wheel, the squeezed water will accumulate in this groove and is likely to flow back into the mop head during the process of gravity or relative movement, resulting in problems such as low water squeezing efficiency, the need for repeated water squeezing, and incomplete water squeezing. The present invention provides a water squeezing component with a compact structure and reasonable design. During the process of squeezing water in cooperation with the mop head, it can not only avoid the formation of a closed groove between the mop head and the water squeezing component, but also enable the squeezed water to be separated from the mop head through the inside of the water squeezing component, effectively preventing the squeezed water from flowing back into the mop head, thereby effectively improving the water squeezing efficiency. The main concept is as follows:

[0007] A water squeezing component for a flat mop, comprising a rotating member. The rotating member includes a water squeezing portion for squeezing the mop head and rotating following the movement of the mop head. A plurality of drainage ports are formed on the outer surface of the water squeezing portion. The drainage ports are used to rotate following the water squeezing portion and guide the squeezed water to flow into the water squeezing portion from the drainage ports when rotating to between the water squeezing portion and the mop head. In this solution, the rotating member includes a water squeezing portion for positively squeezing the mop head, and the water squeezing portion can rotate following the movement of the mop head to achieve continuous rolling contact, which is not only beneficial to realizing continuous water squeezing but also does not damage the mop head, especially suitable for the cotton swab flat mop, and can solve the problem of non-damaging water squeezing of the cotton swab flat mop. In this solution, by forming a plurality of drainage ports on the outer surface of the water squeezing portion, on the one hand, during actual use, the drainage ports can rotate following the rotation of the water squeezing portion, so that the water squeezed out from the flat mop can flow into the water squeezing portion along the drainage ports, realizing the effective separation of water from the mop head, thereby effectively solving the problems of water accumulation and backflow of the squeezed water. On the other hand, since a groove capable of holding water will inevitably form above the contact position between the mop head of the flat mop and the water squeezing portion during the process of squeezing water in cooperation, but after forming the drainage ports, when the drainage ports rotate following the water squeezing portion to the position corresponding to the groove, the drainage ports are communicated with the groove, and the water can automatically flow from the groove into the drainage ports and then into the water squeezing portion under the action of gravity. This not only solves the problem that the water in the groove will accumulate and cannot be efficiently separated from the mop head, but also makes the squeezed water not flow back into the mop head, thus effectively solving the problem of backflow of the squeezed water. Therefore, compared with the prior art, this water squeezing component can not only avoid the formation of a closed groove between the mop head and the water squeezing component, but also enable the squeezed water to be efficiently separated from the mop head through the inside of the water squeezing component, effectively preventing the squeezed water from flowing back into the mop head, thereby significantly improving the water squeezing efficiency.

[0008] Preferably, the water squeezing part is of a cylindrical structure; and / or, the drainage openings are evenly distributed along the circumferential direction of the water squeezing part.

[0009] Preferably, the drainage openings are holes, grooves and / or gaps formed on the outer surface of the water squeezing part.

[0010] To solve the problem of the forming of the water squeezing part, preferably, the water squeezing part is an integrally formed member, or the water squeezing part includes water squeezing strips and two end retaining rings, the two ends of the water squeezing strips are respectively fixed to the two end retaining rings or are respectively rotatably installed on the two end retaining rings, each water squeezing strip is distributed along the circumferential direction of the central axis of the end retaining ring, and there is a set gap between adjacent water squeezing strips, and the gap forms the drainage opening.

[0011] To solve the problem that during the extrusion process between the mop head and the water squeezing part, the mop head is prone to deform towards the two ends of the water squeezing part, resulting in low water squeezing efficiency. Further, the rotary member further includes a restraining part formed on the end of the water squeezing part along the circumferential direction of the central axis of the water squeezing part. The inner side surface of the restraining part close to the water squeezing part is a toroidal surface or a conical surface, and the inner side surface is used to restrain and extrude the mop head. In this solution, by forming a restraining part distributed along the circumferential direction at the end of the water squeezing part, the outer surface of the water squeezing part and the inner side surface of the restraining part can enclose a cavity for extruding and restraining the mop head. When the inner side surface is a toroidal surface, the cavity is rectangular, and when the inner side surface is a conical surface, the cavity is trapezoidal, which can better restrain and extrude the mop head; and by setting the restraining part, the mop head can be effectively restricted and restrained, and it can effectively prevent the mop head from deforming towards the two ends of the water squeezing part during the extrusion process, and can effectively improve the water squeezing efficiency. In addition, the setting of the restraining part can also guide the squeezed water to flow towards the middle of the water squeezing component, thereby solving the problem of the squeezed water leaking to both sides of the water squeezing component.

[0012] Preferably, the restraining part is of an annular structure or a horn-shaped structure; and / or, the water squeezing part and the restraining part are of an integral structure.

[0013] To solve the problem of the backflow of the squeezed water on the restraining part, further, a plurality of drainage openings are formed on the outer surface of the restraining part, and the drainage openings are used to guide the squeezed water to flow into the restraining part from the drainage openings. During the water squeezing process, the squeezed water can be smoothly and efficiently separated from the mop head, thereby effectively preventing the problem of the backflow of the squeezed water, which is very beneficial to improving the water squeezing efficiency.

[0014] To solve the problems of installation and water drainage of the rotating member, further, it further includes a support member adapted to the rotating member and used to support the rotating member. The support member is further constructed with a drainage portion that cooperates with the drainage port, and the drainage portion is used to receive and drain the water flowing into the drainage port. In the solution, by providing the support member, it is convenient to support and restrain the rotating member, and the installation problem of the rotating member can be effectively solved; by constructing the drainage portion, the drainage portion can cooperate with the drainage port, so that the squeezed water can enter the drainage portion through the drainage port and can be away from the mop head through the drainage portion, effectively solving the problems of drainage and diversion of the squeezed water.

[0015] To solve the drainage problem, in one concept, the support member is arranged inside the rotating member. The drainage portion includes a plurality of partition members constructed between the support member and the rotating member, and the partition members are respectively connected to the support member and the rotating member. The adjacent two partition members, the support member, and the rotating member together enclose an inner cavity for drainage; and the drainage ports constructed on the rotating member are respectively connected to the corresponding inner cavities. In this solution, by providing the support member and using the partition members to connect the support member and the rotating member, on the one hand, the support member and the rotating member can be connected as a whole for synchronous rotation, and the two ends of the support member respectively extend out of the rotating member, which is also convenient for the installation of the water squeezing portion. On the other hand, the adjacent two partition members, the support member, and the rotating member can together enclose an inner cavity for drainage, so that there are a plurality of inner cavities distributed along the circumferential direction of the rotation center axis of the rotating member, and the drainage ports constructed on the rotating member are respectively connected to the corresponding inner cavities. During the water squeezing process, the squeezed water can enter the corresponding inner cavity through the drainage port under the action of gravity and can be discharged from one end or both ends of the inner cavity of the water squeezing component. At the same time, the partition members can also play a blocking role, effectively preventing the water entering the inner cavity from flowing out of the inner cavity through the other drainage ports during the rotation process, which can not only achieve the functions of internal drainage and internal water discharge, but also effectively isolate the water from the mop head, thus effectively solving the problem of backflow of the squeezed water.

[0016] Preferably, the support member is a rotating shaft or a rotating cylinder, and / or the support member is arranged at the central position of the rotating member, and / or the partition member is a partition board evenly distributed along the circumferential direction of the rotation center axis of the rotating member.

[0017] Preferably, each inner cavity is respectively connected to a group of drainage ports, and the group of drainage ports includes a plurality of drainage ports distributed along the direction of the rotation center axis of the rotating member. Thus, it can effectively prevent the water entering the inner cavity from flowing out of the inner cavity through the other drainage ports during the rotation process, so that the water entering the inner cavity from a group of drainage ports can only be discharged from one end or both ends of the inner cavity of the water squeezing component.

[0018] To solve the problem of rotatably mounting a rotating member, further, the rotating member is configured with a first cylindrical inner surface or a first cylindrical outer surface, and the support member is configured with a second cylindrical outer surface adapted to the first cylindrical inner surface or a second cylindrical inner surface adapted to the first cylindrical outer surface.

[0019] The rotating member is rotatably disposed on the support member through the cooperation of the first cylindrical inner surface and the second cylindrical outer surface, or the rotating member is rotatably disposed on the support member through the cooperation of the first cylindrical outer surface and the second cylindrical inner surface. In this solution, through the cooperation of the cylindrical inner surface and the cylindrical outer surface, the rotating member and the support member can form a rotational fit, so that the rotating member can rotate relative to the support member.

[0020] To solve the drainage problem, further, the drainage part includes a drainage window formed on the outer surface of the support member and cooperating with the drainage opening, and a flow channel formed inside the support member, and the drainage window is communicated with the flow channel, and the flow channel penetrates through the end of the support member or penetrates through the side wall of the support member extending out of the rotating member. In this solution, by providing a drainage window on the support member, the drainage window is located at a fixed position inside the rotating member, and the drainage opening formed on the rotating member is located outside the drainage window. During the rotation of the rotating member, each drainage opening can be cyclically communicated with the drainage window; by constructing a flow channel, and the flow channel penetrates through the end of the support member or penetrates through the side wall of the support member extending out of the rotating member, so that during the water squeezing process, the squeezed water can enter the drainage window through the drainage opening, and the water entering the drainage window can be smoothly discharged from the support member through the flow channel, which can not only achieve the function of internal drainage and internal water discharge, but also effectively isolate the water from the mop head, thus effectively solving the problem of backflow of the squeezed water and significantly improving the water squeezing efficiency.

[0021] Preferably, the support member is a cylindrical structure, and the drainage window is formed on the side wall of the support member, and the water squeezing part is configured with a central through hole adapted to the support member.

[0022] Preferably, the support member includes a cylindrical barrel adapted to the rotating member and adapter barrels formed at both ends of the cylindrical barrel and adapted to the rotating member, and the drainage windows are respectively formed on the cylindrical barrel and the adapter barrels.

[0023] Preferably, the rotating member is assembled to the support member by clearance fit; or, the rotating member is mounted on the support member by a bearing.

[0024] In order to solve the problem that the squeezed water in the existing squeezing device is easy to flow back into the mop head during use, resulting in low squeezing efficiency, repeated squeezing and incomplete squeezing, a squeezing device for a flat mop is provided, including a squeezing frame and a squeezing component, wherein the squeezing frame is configured with a groove for inserting the mop head, and the squeezing component is arranged on one side of the groove. When in use, the mop head of the flat mop can move up and down in the groove, and the wiping part of the mop head and the squeezing component can be squeezed and moved relative to each other during the up and down movement. In this process, the purpose of squeezing water can be achieved, and the squeezed water can be separated from the mop head along the drainage port during the squeezing process, which can effectively prevent the squeezed water from flowing back to the mop head, and can significantly improve the squeezing efficiency.

[0025] Furthermore, it also includes a roller, which is arranged on the other side of the stroking opening and corresponds to the water squeezing component. By arranging the roller, the water squeezing component and the roller together form a squeezing mechanism for squeezing the mop head, so that after the mop head is vertically inserted into the stroking opening, the back plate of the mop head can contact the roller, and the wiping part of the mop head can contact the water squeezing component and squeeze each other, so that the wiping part and the water squeezing component move relative to each other during the process of pulling up and down, thereby achieving the purpose of squeezing water.

[0026] A cleaning device for a flat mop includes the water squeezing device and a container, wherein the container is configured with an internal space, the water squeezing rack is mounted on the container, and the stroking opening is in communication with the internal space. The cleaning device can be used to clean a flat mop, and by constructing the container, in actual use, the container can be used to receive squeezed water and also to contain water for cleaning the mop head.

[0027] Compared with the prior art, the water squeezing component, water squeezing device and cleaning equipment for a flat mop provided by the present invention have a compact structure and a reasonable design. In the process of squeezing water in cooperation with the mop head, a closed groove can be avoided from being formed between the mop head and the water squeezing component, and the squeezed water can be separated from the mop head through the interior of the water squeezing component, which can effectively prevent the squeezed water from flowing back to the mop head, thereby effectively improving the water squeezing efficiency.

Detailed implementation manners

[0048] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Usually, the components of the embodiments of the present invention described and shown here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed present invention, but only represents the selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts fall within the protection scope of the present invention.

[0049] Embodiment 1

[0050] Please refer to Figures 2 - 6 , in this embodiment, a water squeezing component for a flat mop is provided, including a rotating member. The rotating member includes a water squeezing part 201 for squeezing the mop head 100 and for rotating following the movement of the mop head 100. A plurality of drainage ports 202 are formed on the outer surface of the water squeezing part 201, as Figures 2 - 6As shown, the drainage opening 202 is configured to rotate along with the water squeezing part 201. When it rotates to a position between the water squeezing part 201 and the mop head 100, the drainage opening 202 is used to guide the squeezed water to flow into the water squeezing part 201 through the drainage opening 202, thereby preventing the squeezed water from flowing back to the mop head 100, such that the water squeezing part 201 has the functions of both squeezing water and guiding water.

[0051] Specifically, in this embodiment, the rotary member includes a water squeezing part 201 for positively squeezing the mop head 100, and the water squeezing part 201 can rotate along with the movement of the mop head 100 to achieve continuous rolling contact, which is beneficial for realizing continuous water squeezing and will not damage the mop head 100. It is particularly suitable for the cotton swab flat mop and can solve the problem of non-damaging water squeezing of the cotton swab flat mop. In this solution, a plurality of drainage openings 202 are formed on the outer surface of the water squeezing part 201. During actual use, on the one hand, the drainage openings 202 can rotate along with the rotation of the water squeezing part 201, so that they can continuously contact the flat mop, and the water squeezed out from the flat mop can flow into the water squeezing part 201 along the drainage openings 202 to achieve effective separation of water from the mop head 100, thereby effectively solving the problems of water accumulation and backflow of the squeezed water. On the other hand, since a water-receiving groove will inevitably be formed above the contact position between the mop head 100 of the flat mop and the water squeezing part 201 during the water squeezing cooperation between the mop head 100 and the water squeezing part 201, as Figure 2 and Figure 6 shown. However, after the drainage openings 202 are formed, when the drainage openings 202 rotate along with the water squeezing part 201 to a position corresponding to the groove, the drainage openings 202 are in communication with the groove, and the water can automatically flow from the groove into the drainage openings 202 under the action of gravity and then into the water squeezing part 201. This not only solves the problem that the water in the groove will accumulate and cannot be efficiently separated from the mop head 100, but also prevents the squeezed water from flowing back to the mop head 100, thereby effectively solving the problem of backflow of the squeezed water. Therefore, compared with the prior art, this water squeezing component 200 can not only avoid forming a closed groove between the mop head 100 and the water squeezing part 201, but also enable the squeezed water to be efficiently separated from the mop head 100 through the inside of the water squeezing part 201, effectively preventing the squeezed water from flowing back to the mop head 100, thereby significantly improving the water squeezing efficiency.

[0052] In this embodiment, the water squeezing part 201 preferably adopts a cylindrical structure, as Figure 2 shown, so that during the rotation of the water squeezing part 201, there is a relatively uniform squeezing force between the water squeezing part 201 and the mop head 100, and the water can be squeezed more evenly.

[0053] The distribution of the drainage openings 202 in the water squeezing part 201 can be determined according to actual requirements. In a preferred embodiment, the drainage openings 202 can be evenly distributed along the circumferential direction of the water squeezing part 201; as Figure 2 shown; similarly, the number of the drainage openings 202 can be determined according to actual requirements, as long as the requirements for drainage and water passing are met.

[0054] In this embodiment, the shape of the drainage openings 202 has various embodiments. Preferably, the drainage openings 202 can be holes, grooves or gaps formed on the outer surface of the water squeezing part 201; specifically, the holes can be round holes, slotted holes or polygonal holes, etc. When polygonal holes are adopted, triangles, rectangles, regular pentagons, etc. can be preferentially adopted, and no further examples will be given here.

[0055] In the actual implementation process, the drainage openings 202 can be formed on the water squeezing part 201 irregularly, or can be formed on the water squeezing part 201 according to a certain arrangement rule. Preferably, the drainage openings 202 can be arranged in an array on the water squeezing part 201. In a preferred embodiment, the drainage openings 202 can be arranged along the direction of the rotation center axis of the water squeezing part 201. As an example, as Figure 2 shown, the drainage openings 202 adopt slotted holes with a strip structure, and the length direction of the drainage openings 202 is consistent with the direction of the rotation center axis of the water squeezing part 201, as Figure 2 shown, along the direction of the rotation center axis of the water squeezing part 201, the number of the slotted holes can be one or more, and no further examples will be given here.

[0056] The forming method of the drainage openings 202 also has various embodiments. As an example, the drainage openings 202 can be formed by machining, that is, the water squeezing part can be an integrally formed component. For example, when the water squeezing part 201 is made of metal, the drainage openings 202 can be machined on the water squeezing part 201 by mechanical processing; when the water squeezing part 201 is made of non-metal, such as made of plastic, as Figure 2 shown, the drainage openings 202 can also be formed on the water squeezing part 201 by injection molding; in addition, the drainage openings 202 can also be assembled, that is, the water squeezing part can be an assembled structure. As an example, as Figure 2 shown, the water squeezing part 201 includes several water squeezing strips 204 and two end retaining rings 205. The two ends of the water squeezing strips 204 are respectively fixed to the two end retaining rings 205 or are respectively rotatably installed on the two end retaining rings 205. Each water squeezing strip 204 is distributed along the circumferential direction of the center axis of the end retaining ring 205, as Figure 2 shown, and a set gap is provided between adjacent two water squeezing strips 204, and the gap forms the drainage openings 202, as Figure 2As shown, the squeezed-out water can be discharged from the mop head 100 through the drainage opening 202 formed by the gaps between two adjacent water-squeezing strips 204. The shape of the water-squeezing strip 204 can be determined according to actual needs. For example, the water-squeezing strip 204 can be in a strip structure, and the cross-section of the water-squeezing strip 204 can preferably be circular, annular, triangular, square, etc.

[0057] It can be understood that during the actual implementation process, after the drainage opening 202 is formed on the water-squeezing part 201, the stiffness of the water-squeezing part 201 can be reduced, resulting in the water-squeezing part 201 being prone to deformation during the squeezing process. To solve this problem, during the implementation of the water-squeezing part 201, a number of annular reinforcing ribs 203 can also be formed inside the water-squeezing part 201, such as Figure 12 As shown, preferably, the reinforcing rib 203 can be perpendicular to the length direction of the drainage opening 202, so as to play a role in strengthening the structure.

[0058] In this embodiment, the length of the water-squeezing part 201 is adapted to the width of the mop head 100, so as to evenly squeeze the mop head 100 along the width direction of the mop head 100, which is beneficial to improving the water-squeezing efficiency.

[0059] During the actual implementation, the water-squeezing part 201 needs to be movably installed. To solve the installation problem of the water-squeezing part 201 and the drainage problem of the water inside, in this embodiment, this water-squeezing component further includes a support component that is adapted to the rotary component and is used to support the rotary component, which is convenient for supporting and restricting the rotary component and can effectively solve the installation problem of the rotary component; the support component is also provided with a drainage part that cooperates with the drainage opening, and the drainage part is used to receive and drain the water flowing into the drainage opening; that is, by constructing the drainage part, the drainage part can cooperate with the drainage opening, so that the squeezed-out water can enter the drainage part through the drainage opening and be away from the mop head through the drainage part, which can effectively solve the drainage and diversion problems of the squeezed water.

[0060] The support component and the drainage part respectively have various implementation manners. For example, in this embodiment, the support component is arranged inside the rotary component, and the end of the support component can extend out of the rotary component, such as Figures 4 - 6As shown, in order to install and restrain the support member 206, the end of the support member may not extend out of the rotating member; in this embodiment, the rotating member is rotatably installed on the support member. To solve the problem of the rotatable installation of the rotating member, in this embodiment, the rotating member is configured with a first cylindrical inner surface or a first cylindrical outer surface, and the support member is configured with a second cylindrical outer surface adapted to the first cylindrical inner surface or a second cylindrical inner surface adapted to the first cylindrical outer surface. As shown in the figure, the rotating member is rotatably disposed on the support member through the cooperation of the first cylindrical inner surface and the second cylindrical outer surface, or the rotating member is rotatably disposed on the support member through the cooperation of the first cylindrical outer surface and the second cylindrical inner surface; in this embodiment, through the cooperation of the cylindrical inner surface and the cylindrical outer surface, the rotating member and the support member can form a rotational fit, so that the rotating member can rotate relative to the support member.

[0061] In this embodiment, as Figure 4 shown, the drainage part includes a drainage window 207 constructed on the outer surface of the support member 206 and cooperating with the drainage port, and a flow channel 208 constructed inside the support member 206. The drainage window 207 is communicated with the flow channel 208. The flow channel 208 penetrates the end of the support member 206 or penetrates and extends out of the side wall of the support member of the rotating member, so that water can flow to the outside of the water squeezing part 201 through the flow channel 208, neither flowing back to the mop head nor realizing the function of continuous drainage; specifically, in this embodiment, by providing the drainage window 207 on the support member, the drainage window 207 is located at a fixed position inside the rotating member, and the drainage port 202 constructed on the rotating member is located outside the drainage window 207. During the rotation of the rotating member, each drainage port 202 can be cyclically communicated with the drainage window 207; by constructing the flow channel 208, and the flow channel 208 penetrates the end of the support member 206 or penetrates and extends out of the side wall of the support member of the rotating member, so that during the water squeezing process, the squeezed water can enter the drainage window 207 through the drainage port 202, and the water entering the drainage window 207 can be smoothly discharged from the support member 206 through the flow channel 208, which can not only play the role of internal drainage and internal water discharge, but also effectively isolate water from the mop head 100, thus effectively solving the problem of the backflow of the squeezed water and significantly improving the water squeezing efficiency.

[0062] The shape of the drainage window 207 can be determined according to actual needs. Preferably, the drainage window 207 can preferably adopt a rectangular structure, so as to have sufficient width, be more convenient to match with the drainage ports 202 in the same row, and is beneficial to improving the drainage efficiency.

[0063] During actual use, after the support member 206 is fixedly installed, the position of the drainage window 207 is also fixed. In order to facilitate the reception and transfer of water in the drainage opening 202, the drainage window 207 can preferably be set in an upwardly inclined orientation, such as Figures 4 - 6 as shown, so as to utilize the action of gravity to automatically and efficiently receive the water flowing in from the drainage opening 202.

[0064] The support member 206 has various implementation manners. Preferably, the support member 206 can preferably adopt a cylindrical structure, and the drainage window 207 is constructed on the side wall of the support member, such as Figure 4 as shown. The water squeezing part is constructed with a central through hole adapted to the support member, so that the water squeezing part can be rotatably installed on the support member 206. During actual use, the squeezed water can be discharged from either end of the support member 206 from this water squeezing component, or can be discharged from this water squeezing component through the opening constructed on the side wall of the support member 206, which is very convenient.

[0065] In order to enable the water squeezing part 201 to rotate relative to the support member 206, the rotating member can be assembled to the support member 206 by clearance fit, that is, the outer diameter of the rotating member is less than or slightly less than the inner diameter of the support member 206, so that the rotating member is sleeved on the support member 206, and after the support member 206 is constrained, the rotating member can smoothly rotate relative to the support member 206; in addition, the rotating member can also be installed on the support member 206 through a bearing.

[0066] During the water squeezing process, the rotating member will move relative to the support member 206 under the drive of the mop head 100, and the surface of the rotating member is constructed with a drainage opening 202, so that during the squeezing process, the wiping part on the mop head 100 is easily caught in the gap between the rotating member and the support member 206 through the drainage opening 202, which is likely to damage the mop head 100. To solve this problem, in specific implementation, the depth of the drainage opening 202 can be appropriately increased or the thickness of the rotating member can be increased, so that during the squeezing process, the wiping part on the mop head 100 will not contact the support member 206, thereby effectively preventing the mop head 100 from being damaged during the relative movement between the rotating member and the support member 206.

[0067] Embodiment 2

[0068] To solve the problems of the installation of the water squeezing part 201 and the drainage of the internal water, the main difference between this Embodiment 2 and the above Embodiment 1 is that this Embodiment 2 provides a support member 206 with another structure. Specifically, in this embodiment, the support member 206 is arranged inside the rotating member, and the end of the support member 206 can extend out of the rotating member, such as Figures 7 - 9 as shown, for the movable installation of the support member 206, or it can also not extend out of the rotating member;

[0069] As Figures 7 - 9 shown, in this embodiment, the drainage part includes a plurality of partition members 209 constructed between the support member 206 and the rotary member, and the partition members 209 are respectively connected to the support member 206 and the rotary member. Two adjacent partition members 209, the support member 206, and the rotary member together enclose an inner cavity 210 for drainage, as Figure 7 and Figure 8 shown. The drainage ports 202 constructed on the rotary member are respectively connected to the corresponding inner cavities 210, as Figure 7 and Figure 8 shown. In this embodiment, by providing the support member 206 and using the partition members 209 to connect the support member 206 and the rotary member, on the one hand, the support member 206 and the rotary member can be connected as a whole and can rotate synchronously, and both ends of the support member 206 extend out of the rotary member, which is also convenient for the movable installation of the water squeezing part 201 to follow the rotation of the mop head 100; on the other hand, two adjacent partition members 209, the support member 206, and the rotary member can together enclose an inner cavity 210 for drainage, so that a plurality of inner cavities 210 are distributed along the circumferential direction of the rotation center axis of the rotary member, and the drainage ports 202 constructed on the rotary member are respectively connected to the corresponding inner cavities 210. During the water squeezing process, the squeezed water can enter the corresponding inner cavity 210 through the drainage port 202 under the action of gravity and can be discharged from one end or both ends of the inner cavity 210 of the water squeezing part 201. At the same time, the partition members 209 can also play a blocking role, effectively preventing the water entering the inner cavity 210 from flowing out of the inner cavity 210 through the other drainage ports 202 during the rotation process. It can not only achieve the functions of internal drainage and internal water discharge, but also effectively isolate the water from the mop head 100, thus effectively solving the problem of the backflow of the squeezed water.

[0070] In this embodiment, the support member 206 mainly plays a supporting role. Preferably, the support member 206 can preferably adopt a rotating shaft or a rotating cylinder, which is convenient for the movable installation of the support member 206, and the partition members 209 can be partitions evenly distributed along the circumferential direction of the rotation center axis of the rotary member, as Figure 7 and Figure 8 shown. The support member can be arranged at the central position of the rotary member.

[0071] Preferably, in this embodiment, each inner cavity 210 is respectively communicated with a set of drainage ports 202, and a set of drainage ports 202 includes a plurality of drainage ports 202 distributed along the rotation center axis direction of the rotating member. Thus, it can effectively prevent the water entering the inner cavity 210 during the rotation process from flowing out of the inner cavity 210 through the remaining drainage ports 202 and being possibly absorbed by the mop head 100 again. This solution enables the water entering the inner cavity 210 from a set of drainage ports 202 to be discharged from one or both ends of the inner cavity 210 to the water squeezing part 201 only, achieving strict constraint on the squeezed water and preventing the problem of backflow of the squeezed water. In the specific implementation process, the number of the partition members 209 can be determined according to the implementation requirements, and no further examples will be given here.

[0072] Embodiment 3

[0073] To solve the problem that during the squeezing process between the mop head 100 and the water squeezing part 201, the mop head 100 is prone to deform towards both ends of the water squeezing part 201, resulting in low water squeezing efficiency. The main difference between this Embodiment 3 and the above Embodiment 1 or Embodiment 2 is that in the water squeezing component 200 provided in this embodiment, the rotating member further includes a constraint part 212 constructed at the end of the water squeezing part 201 along the circumferential direction of the rotation center axis of the water squeezing part 201, as Figures 10 - 16 shown. The inner side surface 213 of the constraint part 212 close to the water squeezing part 201 can be a toroidal surface or a conical surface, and the inner side surface 213 is used to constrain and squeeze the mop head 100. Specifically, in this embodiment, by constructing the circumferentially distributed constraint part 212 at the end of the water squeezing part 201, the outer surface of the water squeezing part 201 and the inner side surface 213 of the constraint part 212 can enclose a cavity for squeezing and constraining the mop head 100. When the inner side surface 213 is a toroidal surface, as Figure 10 shown, the cavity is rectangular. When the inner side surface 213 is a conical surface, as Figure 11 shown, the cavity is trapezoidal, which can better constrain and squeeze the mop head 100. And by setting the constraint part 212, the mop head 100 can be effectively restricted and constrained, and it can effectively prevent the mop head 100 from deforming towards both ends of the water squeezing part 201 during the squeezing process, and can effectively improve the water squeezing efficiency.

[0074] Preferably, the constraint part 212 can be an annular structure (at this time, the inner side surface 213 is a toroidal surface, as Figure 10 shown) or a horn-shaped structure (at this time, the inner side surface 213 is a conical surface, as Figure 11 shown); and the water squeezing part 201 and the constraint part 212 can preferably adopt an integral structure.

[0075] In a further solution for further improving the water squeezing efficiency, a plurality of drainage openings 202 are formed on the outer surface of the constraint part 212. The drainage openings 202 are used to guide the squeezed-out water to flow into the constraint part 212 through the drainage openings 202, so that during the water squeezing process, the squeezed-out water can be smoothly and efficiently separated from the mop head 100, thereby effectively preventing the problem of backflow of the squeezed-out water and being very beneficial to improving the water squeezing efficiency.

[0076] It can be understood that the drainage openings 202 formed on the constraint part 212 can have the same shape, structure and arrangement as the drainage openings 202 formed on the water squeezing part 201. As Figure 14 shown, they are mainly used to drain the squeezed-out water, and no further examples will be given here.

[0077] It can be understood that in the specific implementation process, when the rotating member is provided with the constraint part 212, the support member 206 may not be adapted to the constraint part 212, or corresponding components may be constructed to match the constraint part 212. Especially when the constraint part 212 is provided with the drainage openings 202, at this time, the support member 206 includes a cylindrical barrel 214 adapted to the rotating member and an adapter barrel 215 constructed at both ends of the cylindrical barrel 214 and adapted to the rotating member. The drainage windows 207 can be respectively formed on the cylindrical barrel 214 and the adapter barrel 215 to drain and discharge water for the drainage openings 202 of the water squeezing part 201 and the drainage openings 202 of the constraint part 212. As an example, when the constraint parts 212 with a horn-shaped structure are respectively formed at both ends of the water squeezing part 201 and the constraint part 212 is provided with the drainage openings 202, the support member 206 may include a cylindrical barrel 214 and adapter barrels 215 arranged at both ends of the cylindrical barrel 214, and the size of the cylindrical barrel 214 is adapted to the water squeezing part 201, and the adapter barrels 215 are adapted to the horn-shaped constraint parts 212. As Figures 14 - 16 shown, the adapter barrel 215 can also adopt a horn-shaped structure, and the drainage windows 207 can be respectively formed on the cylindrical barrel 214 and the adapter barrel 215, and the adapter barrels 215 can be connected as a whole. As Figure 15 shown, it is more convenient for drainage.

[0078] Embodiment 4

[0079] To solve the problem that in the existing water squeezing device during use, the squeezed-out water easily flows back into the mop head 100, resulting in low water squeezing efficiency, the need for repeated water squeezing, and incomplete squeezing during the water squeezing process, this embodiment provides a water squeezing device for a flat mop, including a water squeezing frame 301 and the water squeezing component 200 described in Embodiment 1 or Embodiment 2 or Embodiment 3. The water squeezing frame 301 can adopt an existing water squeezing frame 301. Preferably, as Figure 17 and Figure 18As shown, the wringer rack 301 is configured with a squeezing opening 302 for inserting the mop head 100. Preferably, the squeezing opening 302 may preferably adopt a T-shaped structure, such as Figure 18 As shown, the squeezing member 200 is disposed on one side of the squeezing opening 302; during use, the mop head 100 of the flat mop can move up and down in the squeezing opening 302, and during the up and down movement, the wiping part of the mop head 100 and the squeezing part 201 can be mutually squeezed and move relatively. In this process, the purpose of squeezing water can be achieved, and during the water squeezing process, the squeezed water can be separated from the mop head 100 along the drainage opening 202, which can effectively prevent the squeezed water from flowing back to the mop head 100 and can significantly improve the water squeezing efficiency.

[0080] Specifically, when the squeezing member 200 in Embodiment 1 is adopted, both ends of the supporting member 206 need to be fixedly installed on the wringer rack 301, and when the squeezing member 200 in Embodiment 2 is adopted, both ends of the supporting member 206 need to be rotatably installed on the wringer rack 301. At this time, since the squeezed water will be drained to one or both ends of the squeezing part 201, a diversion groove 211 usually needs to be provided on the wringer rack 301, and the diversion groove 211 can be disposed below the end of the squeezing part 201, such as Figure 9 As shown, so that the water can fall from the end of the squeezing part 201 to the diversion groove 211 under the action of gravity and can flow along the diversion groove 211, so as to drain the water to the required position and can effectively prevent the water from contacting the mop head 100 again.

[0081] In a more perfect solution, such as Figure 18 As shown, the wringing device further includes rollers 303. The rollers 303 are disposed on the other side of the squeezing opening 302 and correspond to the squeezing member 200. The number of rollers 303 can be two or more. By providing the rollers 303, the squeezing member 200 and the rollers 303 jointly form a squeezing mechanism for squeezing the mop head 100. After the mop head 100 is vertically inserted into the squeezing opening 302, the back plate of the mop head 100 can contact the rollers 303, and the wiping part of the mop head 100 can contact the squeezing member 200 and be mutually squeezed, so that the wiping part and the squeezing member 200 move relatively during the up and down lifting process to achieve the purpose of squeezing water.

[0082] Embodiment 5

[0083] This embodiment provides a cleaning device for a flat mop, including the wringing device described in Embodiment 4 and a container 400. The container 400 is configured with an internal space, and the wringer rack 301 can be installed on the top of the container 400, such as Figure 17 and Figure 18As shown, the squeezing opening 302 is in communication with the internal space so that the mop head 100 can be inserted into the internal space via the squeezing opening 302 and can be repeatedly lifted at the squeezing opening 302 to achieve the purpose of cleaning and water squeezing.

[0084] In this embodiment, the container 400 can be made of plastic and can be in a bucket shape.

[0085] This cleaning device has multiple extended functions. As an implementation manner, this cleaning device includes a container 400. The cleaning device is used for rinsing a flat mop and / or dehydrating the flat mop. At this time, the container 400 is mainly used to receive the squeezed water or rinsing water. In actual use, the squeezed water can be directly discharged into the lower container 400 under the guidance of the water squeezing part 201, or can be discharged from the container 400 through the drain hole formed in the container 400; a rinsing mechanism for rinsing the mop head 100 can also be provided at the squeezing opening 302. For example, a rinsing nozzle can be provided, and the rinsing nozzle is connected to a rinsing water pipe.

[0086] In addition, this cleaning device is also provided with a water tank for storing clean water. The water tank is fixed to the container 400, and the position of the water tank can be higher than the water squeezing component 200. A rinsing nozzle is provided at the squeezing opening 302. The rinsing nozzle is in communication with the water tank, and a valve is provided in the communication path to control whether to discharge clean water or not.

[0087] As another implementation manner, this cleaning device can be provided with a cleaning tank for storing clean water. The cleaning tank is connected to the container 400 and is used for cleaning the mop head 100, and the cleaned mop head 100 can be water-squeezed at the squeezing opening 302, which is very convenient.

[0088] In a more perfect solution, to make the process of pulling the mop head 100 upward more labor-saving, in one solution, the cleaning device further includes a movable bracket, the water squeezing component 200 can be installed on the movable bracket, and the movable bracket is movably installed on the water squeezing frame 301, so that when the mop head 100 moves upward, the distance between the water squeezing component 200 and the other side of the squeezing opening 302 becomes appropriately larger, making the process of pulling the mop head 100 upward more labor-saving. As an example, the movable bracket can be hinged to the water squeezing frame 301, and the water squeezing frame 301 is provided with a lower limit member and an upper limit member, and the lower limit member and the upper limit member are respectively used to restrict the angles of the downward rotation and upward rotation of the movable bracket, so that when the mop head 100 moves upward, the mop head 100 can drive the water squeezing component 200 and the upper part of the interactive bracket to rotate by a certain angle, making the distance between the water squeezing component 200 and the other side of the squeezing opening 302 larger, thus making the process of pulling the mop head 100 upward more labor-saving; similarly, as another example, the two ends of the movable bracket can also be restricted by arranging a slideway on the water squeezing frame 301, and the slideway is inclined, so that when the mop head 100 moves upward, the mop head 100 can drive the water squeezing component 200 and the upper part of the interactive bracket to move by a certain distance, making the distance between the water squeezing component 200 and the other side of the squeezing opening 302 larger, thus making the process of pulling the mop head 100 upward more labor-saving.

[0089] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention.
