[0034] Beneficial effect: It can effectively ensure the effective rotation of the cleaning head between the cleaning position and the squeezing position.

[0035] Furthermore, the drive structure is equipped with a locking element, which can unlock or lock the drive structure onto the cleaning rod. When the cleaning head rotates to the cleaning position, the locking element locks the drive structure onto the cleaning rod, and the limiting structure can restrict the rotation of the cleaning head relative to the cleaning rod.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0057] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0058] The following is combined Figures 1-7 The following describes embodiments of the present invention.

[0059] According to an embodiment of this utility model, a cleaning structure is provided, including a cleaning rod 1, a cleaning head 2, a driving structure, and a limiting structure 32. The cleaning head 2 and the cleaning rod 1 are rotatably connected via a connecting structure 3, so that the cleaning head 2 can rotate relative to the cleaning rod 1. The cleaning head 2 has a squeezing position for squeezing water and a cleaning position for cleaning the surface to be cleaned. The driving structure is movably disposed on the cleaning rod 1. The cleaning head 2 is connected to the driving structure. When the driving structure moves relative to the cleaning rod 1, it can drive the cleaning head 2 to rotate relative to the cleaning rod 1, thereby switching the cleaning head 2 between the squeezing position and the cleaning position. The cleaning head 2 is in an unfolded state during the switching process between the squeezing position and the cleaning position. The limiting structure 32 is disposed on the connecting structure 3. The limiting structure 32 is used to restrict the rotation of the cleaning head 2 relative to the cleaning rod 1 when it is in the cleaning position.

[0060] This application employs a drive structure, allowing users to easily switch the position of the cleaning head 2 simply by operating the drive structure, eliminating the need for laborious manual adjustments. This method significantly reduces the physical exertion and time costs for users during the cleaning process, making the entire cleaning job easier and more efficient.

[0061] In this cleaning structure, the limiting structure 32 plays a crucial role when the cleaning head 2 is in the cleaning position. Once the cleaning head 2 enters the cleaning position, the limiting structure 32 quickly restricts its rotation relative to the cleaning rod 1, ensuring that the cleaning head 2 maintains a stable working posture throughout the cleaning process. When the user pushes the cleaning rod 1 to perform the cleaning operation, there is no need to frequently adjust the direction of the cleaning head 2 as with traditional cleaning tools; the cleaning action can be completed in one smooth motion, significantly improving the continuity of the cleaning action and thus greatly increasing cleaning efficiency.

[0062] Specifically, when the cleaning head 2 is in the cleaning position, the limiting structure 32 restricts its rotation relative to the cleaning rod 1, ensuring the stability of the cleaning head 2 during the cleaning process. This allows the cleaning head 2 to fit more closely and stably against the surface to be cleaned, thereby removing stains and dust more effectively and improving cleaning quality. For example, when cleaning a floor, the cleaning head 2 will not miss any areas due to shaking, ensuring a comprehensive and thorough cleaning.

[0063] Furthermore, the cleaning head 2 remains in an unfolded state during the switching between the squeezing and cleaning positions, thus preventing potential damage caused by folding or bending.

[0064] In this application, the unfolded state of the cleaning head 2 refers to a state where the cleaning head 2 is not folded, bent, or kinked. For example, if the cleaning head 2 includes a cleaning plate and a cleaning component is mounted on the cleaning plate, the unfolded state means that the cleaning component can be unfolded. If the cleaning component is a sponge head, it means that the sponge head unfolds itself. If the cleaning component is a wiping cloth, it means that the wiping cloth is laid flat on the cleaning plate. The shape of the cleaning head 2 can also be any shape, such as triangle, circle, quadrilateral, polygon, or irregular shape. For example, if the cleaning head 2 is folded in half to wring out water, then the unfolded state of the cleaning head 2, relative to folding and wringing out water, means that the entire cleaning surface of the cleaning head 2 is approximately on the same plane.

[0065] In this application, the surface to be cleaned can be any surface that needs to be cleaned, such as the ground, glass, window, or wall; that is, the cleaning structure of this application can be a glass cleaner, mop, table cleaner, etc.

[0066] In this application, the cleaning head 2 is in the unfolded state during the switching between the squeezing position and the cleaning position; that is, the cleaning head 2 rotates relative to the cleaning rod 1 in the unfolded state. When the cleaning head 2 rotates to the squeezing position, it can be folded in half to squeeze water, or it can continue to squeeze water in the unfolded state; or other squeezing methods.

[0067] In some embodiments, the cleaning head 2 is in an unfolded state when squeezing water in the squeezing position; that is, the cleaning head 2 is in an unfolded state in both the squeezing and cleaning positions, and is also in an unfolded state when squeezing water in the squeezing position; when the cleaning head 2 is rotated to the squeezing position, water can be squeezed out of the cleaning head 2 through the external spout; at this time, a wiping cloth or cotton head can be provided on the cleaning head 2; the external spout can be a spout with squeezing or scraping function provided in the cleaning container; for example, a squeezing port is provided in the cleaning container, and the squeezing port has rollers, scrapers, etc.; or the inner wall of the squeezing port is provided with protrusions or other structures that can squeeze the cleaning head 2.

[0068] Furthermore, a sleeve is provided on the cleaning rod 1, and the cleaning head 2 is connected to the drive structure. When the cleaning head 2 is in the wringing position, it is also in the unfolded state. That is, the cleaning head 2 is in the unfolded state in both the wringing and cleaning positions, and it is also in the unfolded state when wringing. When the cleaning head 2 rotates to the wringing position, the drive structure continues to move on the mop handle, which can drive the cleaning head 2 into the sleeve to squeeze and wring water out of the cleaning head 2. Similarly, when it is necessary to clean the surface to be cleaned, the drive structure moves on the cleaning rod 1, which drives the cleaning head 2 out of the sleeve and moves to the wringing position. At this time, the drive structure continues to move and can drive the cleaning head 2 to rotate to the cleaning position. The sleeve can be a ring structure with rollers, scrapers, etc. inside the ring structure; or the inner wall of the ring structure can be provided with protrusions or other structures that can squeeze the cleaning head 2.

[0069] Furthermore, at the squeezing position, the cleaning component on the cleaning head 2 can deform to squeeze out water; the cleaning head 2 remains in an unfolded state; for example, a cotton head is provided on the cleaning head 2; both the cleaning head 2 and the cotton head are elongated; one end of the cotton head is fixed to the first end of the cleaning head 2; the second end of the cotton head is movable in the length direction of the cleaning head 2; then at the squeezing position, the second end of the cotton head can be moved in the length direction of the cleaning head 2 by means of an external boss, so as to deform the cotton head and squeeze out water.

[0070] In this embodiment, the cleaning head 2 includes a cleaning plate, on which cleaning components can be detachably or fixedly mounted; the cleaning components can be cotton heads, wiping cloths, scraping structures, etc.

[0071] In some embodiments, the cleaning head 2 is in a folded state when squeezing water in the squeezing position, that is, the cleaning head 2 is in an unfolded state during the switching process between the squeezing position and the cleaning position; when the cleaning head 2 is rotated to the squeezing position, the cleaning head 2 can be folded in half to squeeze water, that is, the squeezing method of the cleaning head 2 is folding and squeezing.

[0072] In this embodiment, the cleaning head 2 includes a cleaning plate on which cleaning components can be mounted. The cleaning plate includes a middle plate and two side plates respectively hinged to both sides of the middle plate. The unfolded state of the cleaning head 2 means that the two side plates and the middle plate are approximately on the same plane. The squeezing state means that the two side plates rotate relative to the middle plate to squeeze the cleaning components on the cleaning plate, thereby squeezing out water from the cleaning components. The cleaning components include cotton heads, which are detachably or fixedly mounted on the cleaning plate. The detachable connection can be achieved by snap-fit, hook-fit, or other methods.

[0073] This application also discloses some embodiments in which the limiting structure 32 can effectively limit the improper rotation of the cleaning head 2 when it is in the cleaning position and the squeezing position.

[0074] In this embodiment, a limiting structure 32 is used to restrict improper rotation of the cleaning head 2 when it is in the cleaning position. When the drive structure moves the cleaning head 2, the cleaning head 2 disengages from the limiting structure 32. When the cleaning head 2 rotates to the squeezing position, it is again restricted by the limiting structure 32. This configuration is simple, has a good limiting effect, and is inexpensive.

[0075] In this embodiment, when the cleaning head 2 rotates to the squeezing position, the limiting structure 32 can restrict the rotation of the cleaning head 2 relative to the cleaning rod 1.

[0076] In this embodiment, the limiting structure 32 includes a first limiting structure 321 and a second limiting structure 322. The first limiting structure 321 is used to limit the cleaning head 2 from rotating relative to the cleaning rod 1 when it is in the squeezing position; the second limiting structure 322 is used to limit the cleaning head 2 from rotating relative to the cleaning rod 1 when it is in the cleaning position.

[0077] This design prevents excessive localized wear on the cleaning head 2 due to accidental force or rotation during the cleaning process. During the wringing process, the cleaning head 2 remains stably in the optimal position, preventing unnecessary pressure damage from the wringing device due to positional deviation. For example, if the cleaning head 2 shifts position during wringing, the wringing device might apply excessive pressure to one side, leading to accelerated wear on that side. The limiting function of this cleaning structure effectively prevents such occurrences, thereby extending the service life of the cleaning head 2 and reducing the frequency and cost of replacement for users.

[0078] In some embodiments, the first limiting structure 321 can be a first protrusion and a first groove that are mutually adapted. This mutually adapted structure provides precise positioning of the cleaning head 2 when it is in the squeezing position. When the cleaning head 2 rotates to the squeezing position, the first protrusion accurately engages in the first groove, strictly limiting the rotation of the cleaning head 2 relative to the cleaning rod 1, ensuring that the cleaning head 2 is in a stable squeezing posture. This precise positioning ensures smooth squeezing operation, avoiding insufficient or uneven squeezing due to shaking of the cleaning head 2, thus improving the efficiency and effectiveness of squeezing.

[0079] In some embodiments, the second limiting structure 322 can be a second protrusion and a second groove that fit together. When the cleaning head 2 is in the cleaning position, the second protrusion and the second groove engage with each other, precisely limiting the rotation of the cleaning head 2 relative to the cleaning rod 1. This allows the cleaning head 2 to maintain a fixed angle and position during cleaning, closely conforming to the surface to be cleaned, thereby removing stains more effectively. For example, when cleaning walls or floors, the cleaning head 2 will not miss any areas due to shaking, ensuring the quality and effectiveness of the cleaning work and improving the accuracy and comprehensiveness of the cleaning.

[0080] This application also discloses some embodiments. The mating parts of the protrusions and grooves in this application can be made of wear-resistant materials. During the process of the cleaning head 2 frequently switching between the squeezing position and the cleaning position, it can effectively resist friction and wear, and extend the service life of the limiting structure 32.

[0081] Furthermore, the raised and recessed design not only facilitates installation but is also relatively simple and robust. The fit between the raised and recessed sections can withstand various forces generated during cleaning, such as friction and pressure, and is less prone to loosening or damage.

[0082] In some embodiments, when the cleaning head 2 is in the cleaning position, the first limiting structure 321 limits the rotation of the cleaning head 2 relative to the cleaning rod 1; when the driving structure drives the cleaning head 2 to rotate from the cleaning position to the squeezing position, it can drive the first cleaning head 2 to disengage from the limitation of the first limiting structure 321 and rotate to the squeezing position. At this time, the second limiting structure 322 limits the cleaning head 2 to prevent the cleaning head 2 from rotating relative to the rod in the squeezing position.

[0083] In some embodiments, the first limiting structure 321 may be a first snap-fit ​​structure.

[0084] In some embodiments, the second limiting structure 322 may be a second snap-fit ​​structure.

[0085] The locking structure 32 is simple to operate; the user only needs to rotate the cleaning head 2 to the corresponding position, and the locking structure will automatically engage or engage with a simple press to achieve the locking function. Similarly, releasing the locking is also simple; a gentle flick or press on a specific part will disengage the cleaning head 2 from the locking position, allowing the user to continue with other operations. This convenient operation method greatly improves the efficiency of using cleaning tools.

[0086] In some embodiments, the drive structure includes a drive sleeve that is fitted onto the cleaning rod 1, and the movable drive sleeve is connected to the cleaning head 2 via a pull rod or similar structure. Using a drive sleeve fitted onto the cleaning rod 1 results in a compact overall structure, convenient driving, and good driving effect.

[0087] In some embodiments, the drive structure moves on the cleaning rod 1 and can also drive the cleaning head 2 to switch from an unfolded state to a folded squeezing state when it is in the squeezing position.

[0088] In some embodiments, the driving structure may include a driving block, a guide rail on the cleaning rod 1, and a guide structure on the driving block. The guide structure is movably mounted on the guide rail to drive the cleaning head 2 to rotate between a squeezing position and a cleaning position. This arrangement results in a smaller driving block, making the overall cleaning structure more aesthetically pleasing.

[0089] Furthermore, the guide rail can be a strip-shaped hole, and a drive shaft is provided on the drive block. The drive block is located outside the cleaning rod 1, and the drive shaft extends into the cleaning rod 1 through the strip-shaped hole. A limiting block connected to the drive shaft is provided inside the cleaning rod 1. The size of the limiting block and the drive block is larger than the width of the strip-shaped hole. The size of the drive shaft is adapted to the width of the strip-shaped hole, and the limiting block can prevent the drive block from disengaging from the strip-shaped hole. The limiting block is connected to the cleaning head 2 through a pull rod. The limiting block moves on the strip-shaped hole to drive the cleaning head 2 to rotate between the squeezing position and the cleaning position.

[0090] This application also discloses several embodiments in which the connecting structure 3 is rotatably connected to at least one of the cleaning head 2 and the cleaning rod 1; a limiting structure 32 is disposed at the rotatable connection position to restrict the cleaning head 2 from rotating relative to the cleaning rod 1 when in the cleaning position. This allows the cleaning structure to flexibly adapt to different cleaning scenarios. Whether cleaning floors, walls, or other specially shaped surfaces, the cleaning head 2 can remain stable in a suitable position through the limiting structure 32, meeting diverse cleaning needs and improving the versatility and practicality of cleaning tools.

[0091] By placing the limiting structure 32 at the rotational connection position, the rotation of the cleaning head 2 relative to the cleaning rod 1 can be directly and precisely restricted when the cleaning head 2 is in the cleaning position. For example, when the connecting structure 3 is rotatably connected to the cleaning head 2, a limiting structure 32, such as a mutually adaptable protrusion and groove, is set at this rotational connection position. When the cleaning head 2 rotates to the cleaning position, the protrusion is embedded in the groove, which can precisely prevent the cleaning head 2 from rotating further, ensuring that the cleaning head 2 maintains a stable working angle during the cleaning process, thereby improving the accuracy and effectiveness of cleaning.

[0092] In this application, the rotatable connection can be achieved by having a rotating shaft 214 on one side and a shaft hole 311 on the other side, with the rotating shaft 214 rotatably disposed in the shaft hole 311 to form a rotatable connection; alternatively, a hinge or other rotatable structure can be used to form a rotatable connection. The structure is simple, low-cost, and provides good rotational performance.

[0093] In some embodiments, the connecting structure 3 is fixedly connected to the cleaning rod 1 and rotatably connected to the cleaning head 2; the limiting structure 32 is disposed at the rotatable connection position to restrict the relative rotation of the connecting structure 3 and the cleaning head 2, thereby restricting the rotation of the cleaning head 2 relative to the cleaning rod 1. Here, "fixed connection" refers to no relative rotation; it can be a detachable connection, an integral installation, or a fastener used to fix the connecting structure 3 to the cleaning rod 1.

[0094] In some embodiments, the connecting structure 3 is fixedly connected to the cleaning head 2 and rotatably connected to the cleaning rod 1; the limiting structure 32 is disposed at the rotatable connection position to limit the relative rotation of the cleaning head 2 relative to the cleaning rod 1 caused by the connecting structure 3, thereby limiting the rotation of the cleaning head 2 relative to the cleaning rod 1. The fixed connection here refers to no relative rotation, and can be a detachable connection, an integral part, or a fastener used to fix the connecting structure 3 to the cleaning head 2.

[0095] In some embodiments, the connecting structure 3 is rotatably connected to the cleaning rod 1 and the cleaning head 2; a limiting structure 32 is provided between the connecting structure 3 and the cleaning rod 1, and a limiting structure 32 is also provided between the cleaning head 2 and the connecting structure 3; when the cleaning head 2 is in the cleaning position, both limiting structures 32 form a rotation restriction, so that neither the cleaning head 2 nor the cleaning rod 1 can rotate relative to the connecting structure 3, thereby restricting the rotation of the cleaning head 2 relative to the cleaning rod 1.

[0113] This application also discloses some embodiments in which the connecting structure 3 includes a connecting rod, one end of which is connected to the cleaning rod 1 and the other end is connected to the cleaning head 2.

[0114] This application also discloses some embodiments in which, when the cleaning head 2 is provided with a rotating connector 21, the rotating connector 21 is provided with a mounting groove 211, and the mounting groove 211 is used to install the scraping component 212.

[0115] This application also discloses some embodiments in which, when the cleaning head 2 is provided with a rotating connector 21, the cleaning head 2 includes a cleaning plate, and the cleaning plate is provided with a detachable or fixedly connected wiping member; the rotating connector 21 is provided on the back of the cleaning plate.

[0116] This application also discloses some embodiments, in which the driving structure includes a squeezing structure 4. When the cleaning head 2 is in the squeezing position, the squeezing structure 4 moves relative to the cleaning rod 1 and can drive the cleaning head 2 to fold and squeeze out water.

[0117] In this embodiment, the squeezing structure 4 is rotatably connected to the cleaning head 2; and the rotation axis of the cleaning head 2 on the squeezing structure 4 is the first axis; the connection position between the cleaning head 2 and the connecting structure 3 is offset from the first axis; and / or, the squeezing structure 4 includes a sleeve and a V-shaped structure, one end of the sleeve is connected to the tip of the V-shaped structure, and the open end of the V-shaped structure is connected to the cleaning head 2; the sleeve is movably sleeved on the cleaning rod 1.

[0118] In this embodiment, as the squeezing structure 4 moves in the direction close to the first end of the cleaning rod 1, it drives the cleaning head 2 to rotate from the cleaning position to the squeezing position, and then drives the cleaning head 2 to fold and squeeze out water; as the squeezing structure 4 moves in the direction away from the first end of the cleaning rod 1, it drives the cleaning head 2 to unfold, and then drives the cleaning head 2 to rotate from the squeezing position to the cleaning position.

[0119] In some embodiments, the cleaning head 2 is tilted relative to the cleaning rod 1 when in the cleaning position; this better suits the user's cleaning habits and improves the user experience.

[0120] In some embodiments, when the cleaning head 2 is in the wringing position, it is perpendicular to the cleaning rod 1.

[0121] Specifically, the cleaning head 2 includes a rectangular cleaning plate with cotton heads mounted on it; the rectangular cleaning plate includes a middle plate and side plates hinged to both sides of the middle plate; the driving structure includes a squeezing structure 4.

[0122] This application also discloses some embodiments in which the connecting structure 3 is non-rotatably connected to the cleaning rod 1, and the connecting structure 3 is rotatably connected to the cleaning head 2.

[0123] Furthermore, the squeezing structure 4 is rotatably connected to the cleaning head 2; and the rotation axis of the cleaning head 2 on the squeezing structure 4 is the first axis; the connection position between the cleaning head 2 and the connecting structure 3 is offset from the first axis.

[0124] In some embodiments, the cross-sectional shape of the shaft hole 311 is racetrack-shaped; when the cleaning head 2 rotates between the cleaning position and the squeezing position, the rotating shaft 214 moves between the two ends of the shaft hole 311. Specifically, when the cross-sectional shape of the shaft hole 311 is racetrack-shaped, the length direction of the cross-section of the shaft hole 311 is inclined relative to the extension direction of the cleaning rod 1.

[0125] In this embodiment, since the connection position between the cleaning head 2 and the connecting structure 3 is offset from the first axis, when the cleaning head 2 rotates between the squeezing position and the cleaning position, it will simultaneously generate displacements perpendicular to and parallel to the cleaning rod 1. Here, a racetrack-shaped shaft hole 311 is used, and the length direction of the cross-section of the shaft hole 311 is inclined relative to the extension direction of the cleaning rod 1. During the rotation of the cleaning head 2 between the squeezing position and the cleaning position, the movement within the racetrack-shaped shaft hole 311 can ensure that the cleaning head 2 can smoothly switch between the squeezing position and the cleaning position.

[0126] This application also discloses some embodiments in which the connecting structure 3 is rotatably connected to the cleaning rod 1; the connecting structure 3 is rotatably connected to the cleaning head 2; the cross-sectional shape of the shaft hole 311 is circular; at this time, since the connecting structure 3 is rotatably connected to both the cleaning rod 1 and the cleaning head 2, it can ensure that the cleaning head 2 can smoothly switch between the squeezing position and the cleaning position.

[0127] In this embodiment, the working process of this product includes:

[0128] In the initial state, the cleaning head 2 is in the cleaning position; at this time, the cleaning plate is in the unfolded state, that is, the middle plate and the side plate are unfolded and are roughly on the same plane; the cleaning plate as a whole is inclined to the cleaning rod 1; at this time, the limiting structure 32 can restrict the rotation of the cleaning head 2;

[0129] After cleaning is completed; the drive structure is unlocked, allowing it to move on the cleaning rod 1, causing the cleaning plate to rotate to a position perpendicular to the cleaning rod 1. At this time, the cleaning head 2 rotates to the wringing position; the cleaning plate remains in the unfolded state throughout the process.

[0130] After rotating to the squeezing position, the drive structure continues to move on the cleaning rod 1, driving the two side plates of the cleaning plate to rotate relative to the middle plate, so as to fold and squeeze the cotton head on the cleaning plate.

[0131] Similarly, the process of the cleaning head returning to its initial cleaning position from the wringing position includes:

[0132] The drive structure moves on the cleaning rod 1, causing the cleaning plate to unfold from the folded state. During this process, the cleaning head is in the wringing position.

[0133] Then, the drive mechanism continues to move on the cleaning rod 1, driving the cleaning head 2 to rotate to the cleaning position.

[0134] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by this application.
