[0053] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0054] Example 1

[0055] like Figure 1-Figure 3 The utility model provides a cleaning device, comprising: a rod body 1, a cleaning head and a driving unit.

[0056] The rod body 1 is in the shape of a straight rod, and part of the structure can be adjusted to have an arc or bend as needed. A section away from the cleaning head can be provided with additional structures such as a hook.

[0057] The cleaning head is plate-shaped, and has a first cleaning member 21 and a second cleaning member 22 distributed circumferentially. Specifically, the cleaning members are all arranged at the edge of the cleaning head and may also partially extend onto the plate surface. Preferably, a single cleaning member is arranged corresponding to the single-side edge of the cleaning head. It can be understood that three or more cleaning members can be arranged on the cleaning head.

[0058] The cleaning head is rotatably connected to the rod body 1, so that the cleaning head can drive the first cleaning member 21 and the second cleaning member 22 to rotate relative to the rod body 1 along the circumference of the cleaning head to switch the first cleaning member 21 and the second cleaning member 22;

[0059] The driving unit is arranged on the rod body 1 and is used to drive the cleaning head to rotate relative to the rod body 1 .

[0060] Specifically, the cleaning member can be one of a wiping cloth, a scraping strip, and a brush plate. Below, the first cleaning member 21 is a wiping cloth, and the second cleaning member 22 is a scraping strip for example.

[0061] like Figure 1 As shown, users generally use the cleaning head to clean the cleaning member away from the rod body, such as Figure 1 The position at the bottom of the cleaning device is referred to as the "cleaning position" below.

[0062] When cleaning glass, users tend to scrub the glass clean first and then scrape off any remaining water stains. Therefore, when using the cleaning device provided in this embodiment, the driving unit first drives the cleaning head to rotate relative to the rod body 1, causing the first cleaning member 21 and the second cleaning member 22 to rotate relative to the rod body 1 along the circumference of the cleaning head to switch the first cleaning member 21 (wiping cloth) to the cleaning position, thereby completing the switching. Then, the rod body 1 is held to scrub the glass with the first cleaning member 21. When scrubbing is complete, the driving unit switches the second cleaning member 22 (scraping strip) to the cleaning position, allowing the second cleaning member 22 to scrape off the water stains on the glass.

[0063] By respectively arranging at least a first cleaning member 21 and a second cleaning member 22 on the cleaning head, and cooperating with the driving unit, the cleaning head is driven to rotate relative to the rod body 1, so as to realize the conversion of the positions of the first cleaning member 21 and the second cleaning member 22 relative to the surface to be cleaned, thereby realizing the adjustment of the cleaning members. Different cleaning members can be set according to the cleaning objects on the surface to be cleaned, effectively improving the applicability of the cleaning device for different scenes and improving the user experience. At the same time, setting the cleaning head to be plate-shaped not only provides an installation basis for different cleaning members, expands the cleaning range of the cleaning members, and facilitates the rotation and conversion of the positions of the cleaning members on the cleaning head, but also makes it easier for the user to manually stagger the travel direction of the cleaning members and the rotation direction of the cleaning head when holding the rod body 1, which is convenient for manual locking. In addition, the side space of the cleaning head is large, providing space for the installation of other functional structures.

[0064] In addition, since the cleaning head will be contaminated during the cleaning process, directly driving the cleaning head will dirty the user's hands. However, the driving member is provided on the rod body 1, and the driving member 5 drives the cleaning head to rotate relative to the rod body 1, so the user does not need to touch the cleaning head, thus avoiding the risk of dirtying the hands.

[0065] The cleaning head is provided with a plurality of cleaning surfaces 23 distributed circumferentially, each of which is provided with a corresponding cleaning element, including a first cleaning element 21 and a second cleaning element 22. In this embodiment, the number of cleaning surfaces 23 is three, but more is possible. As an alternative embodiment, some cleaning surfaces 23 may be provided with no cleaning elements, or a single cleaning surface 23 may be provided with at least two cleaning elements.

[0066] Preferably, the cleaning head is triangular in shape along the radial cross-section, with three cleaning surfaces 23 distributed circumferentially. The triangular cross-section configuration provides, on the one hand, a more stable and stronger cleaning head structure, and, on the other hand, a more balanced number of cleaning surfaces 23, allowing the user to quickly adjust to the desired cleaning element while ensuring the number of cleaning elements is appropriate for the user's common needs.

[0067] Specifically, the three cleaning parts can be a rag, a scraper, and a brush plate. When using, the user can first switch the rag to the cleaning position and use it to wipe the glass; then switch the brush plate to the cleaning position and use it to wipe off stubborn stains on the glass; finally, switch the scraper to the cleaning position and use it to scrape off water stains on the glass.

[0068] As a convertible embodiment, the cleaning head can also be provided in the form of a quadrilateral plate, a pentagon, etc.

[0069] In this embodiment, the drive unit includes a drive member 4 and a transmission member 5. The drive member 4 can be powered by manual, electric, or pneumatic means, but in this embodiment, it is manually powered. The drive member 4 is movably connected to the rod body 1 and is adapted to move relative to the rod body 1 under the action of an external force. The drive member 4 is also dynamically connected to the cleaning head via the transmission member 5, and is adapted to drive the cleaning head to rotate relative to the rod body 1 via the transmission member 5.

[0070] As a convertible embodiment, the driving unit may only include a power piece, which is directly inserted into the cleaning head and coaxially arranged with the cleaning head to directly drive the cleaning head to rotate relative to the rod body 1.

[0071] The transmission member 5 includes a turntable 501, which is preferably a perfect circle. A central axis 502 extends through the rod body 1 and flexibly engages with the rod body 1. It is understood that the central axis 502 may also be a portion of the rod body 1 and extend through the turntable 501. The turntable 501 is dynamically connected to the cleaning head, such that when the turntable 501 rotates relative to the rod body 1 under external force, it drives the cleaning head to rotate. Preferably, the central axis 502 is perpendicular to the rod body 1. It is understood that the angle may also be acute, depending on cleaning needs.

[0072] In this embodiment, the driving member 4 includes a gripping portion 41 disposed on the turntable 501 , and the gripping portion 41 is eccentrically disposed with respect to the central axis 502 .

[0073] The gripping portion 41 is provided on the turntable 501 , and the turntable 41 can be directly driven to rotate by the gripping portion 501 , thereby driving the cleaning head to rotate. The structure is stable, simple, and low in cost.

[0074] In this embodiment, the driving unit includes a driving member 4 and a transmission member 5. The driving member 4 is movably connected to the rod body 1 and is suitable for moving relative to the rod body 1 under the action of external force; the driving member 4 is dynamically connected to the cleaning head through the transmission member 5, and is suitable for driving the cleaning head to rotate relative to the rod body 1 through the transmission member 5. In addition, the rod body 1 is provided with a limiting device for limiting the movement of the driving member 4 relative to the rod body 1.

[0075] By setting a limit device, the driving member 4 can be locked, and the linkage among the driving member 4, the transmission member 5 and the turntable 501 can be locked, thereby locking the rotation of the cleaning head, ensuring that the cleaning head and the rod body 1 have a fixed relative angle, which is convenient for users to clean.

[0076] In this embodiment, the limiting device includes a first limiting portion provided on the rod body 1, a first clamping member 11 is provided on the first limiting portion, and a second clamping member 411 is provided on the holding portion 41 to cooperate with the first clamping member 11; the first clamping member 11 and the second clamping member 411 are suitable for axial relative movement along the central axis 502, so that the first clamping member 11 and the second clamping member 411 have a clamping position and an unlocking position.

[0077] In this embodiment, the grip portion 41 is disposed on the turntable 501 and is adapted to move axially along the central axis 502. Specifically, a grip shaft is provided on the inner side of the grip portion 41 and is connected to the turntable 501. The grip shaft is relatively eccentric and parallel to the central axis 502. The grip portion 41 can rotate relative to the grip shaft, thereby enabling the grip portion 41 to drive the turntable 501 to rotate under the action of an external force. Preferably, the grip portion 41 is disposed along the side of the turntable 501 facing away from the rod body 1. Specifically, the grip portion 41 can move axially along the grip shaft, thereby achieving relative movement of the first clamping member 11 and the second clamping member 411 along the axial direction of the central axis 502.

[0078] The setting of the grip portion 41 can not only serve as a force-bearing structure for the user to manually drive the turntable 501 to rotate, but also can form an unlockable limiting matching relationship with the first clamping member 11 on the rod body 1 through the setting of the second clamping member 411 thereon, thereby realizing manual locking and unlocking of the turntable 501 and improving the convenience of operation.

[0079] As a convertible embodiment, the first clamping member 11 can also be movably arranged on the rod body 1 along the axial direction of the central axis 502 , or both can be movably arranged along the axial direction of the central axis 502 .

[0080] In addition, one of the first clamping member 11 and the second clamping member 411 is a clamping slot, and the other is a clamping block. It is understandable that both can also be other detachable limiting structures such as hooks, hooks, etc.

[0081] In this embodiment, the first clamping member 11 is arranged in a bent shape, with one end fixedly connected to the rod body 1 and the other end bent toward the turntable 501 and parallel to the turntable 501 or with a small inclination angle, and a clamping groove is formed on it. The second clamping member 411 is arranged in a block-shaped protrusion on the gripping portion 41.

[0082] Preferably, the cleaning head rotates in a direction relative to the rod body 1 .

[0083] The directional rotation setting can, on the one hand, simplify the user's operating actions and improve the user's usability experience; on the other hand, the directional rotation method can avoid severe wear of local positions caused by the user's high-frequency and short-distance forward and reverse rotation, thereby ensuring the service life of the device. Since the user needs to traverse various cleaning parts, it is also convenient for manufacturers to promote and try out different cleaning parts. If the user has a preferred preference, it can also be achieved by adjusting the shape of the cleaning head, limiting the number of cleaning surfaces 23 on the cleaning head, and setting the cleaning surface 23 and the cleaning part to be detachable.

[0084] As a convertible embodiment, the user can freely control the rotation direction of the cleaning head relative to the rod body 1 through structures such as a driving unit.

[0085] Specifically, a one-way limiting mechanism is provided between the cleaning head and the rod body 1, and is used to limit the directional rotation of the cleaning head relative to the rod body 1. Preferably, the one-way limiting mechanism is a ratchet mechanism, which is not shown in the figure. As a convertible embodiment, the one-way limiting mechanism can be a structure such as a one-way needle bearing.

[0086] Furthermore, the cleaning head comprises a mounting plate 2 and a first rotation axis 3 .

[0087] In this embodiment, the first cleaning member 21 and the second cleaning member 22 are distributed circumferentially around the mounting plate 2, which is rotatably connected to the rod body 1 via a first rotational axis 3. Specifically, the first rotational axis 3 is rotatably connected to the rod body 1 and fixedly connected to the mounting plate 2. The drive unit is cooperatively connected to the first rotational axis 3, and by driving the first rotational axis 3 to rotate relative to the rod body 1, it indirectly drives the mounting plate 2 to rotate relative to the rod body 1 along the first rotational axis 3.

[0088] Furthermore, when the driving unit indirectly drives the mounting plate 2 via the first rotating shaft 3 , a first gear member 6 is provided on the first rotating shaft 3 , and a second gear member 7 is installed on the transmission member 5 , and the two are meshed with each other.

[0089] As a convertible embodiment, the driving unit directly drives the mounting plate 2 to rotate relative to the rod body 1 along the first rotation axis 3 through a cooperative connection with the mounting plate 2 .

[0090] Furthermore, the driving unit directly drives the mounting plate 2 to rotate relative to the rod body 1 along the first rotation axis 3 through the matching connection with the mounting plate 2, and the transmission member 5 is directly connected to the mounting plate 2 by power, and can also be matched through gear meshing.

[0091] As another convertible embodiment, the cleaning head does not include the first rotating shaft 3, and a second rotating shaft is provided on the rod body 1. The cleaning head is independently provided relative to the second rotating shaft, and the two rotate relative to each other. The driving unit drives the cleaning head to rotate relative to the second rotating shaft, and the transmission member 5 is power-connected to the cleaning head, and the transmission member 5 is engaged with the cleaning head through gears.

[0092] Example 2

[0093] like Figure 4-Figure 6 Based on Example 1, this embodiment makes adjustments to the structure of the driving unit.

[0094] In this embodiment, the drive unit also includes a drive member 4, a transmission member 5, a turntable 501, and a limit device. In addition, the drive member 4 also includes a sliding member 42, and the transmission member 5 also includes a connecting member 503. The sliding member 42 is provided on the rod body 1 and can slide along the axial direction of the rod body 1. The ends of the connecting member 503 are hinged to the sliding member 42 and the turntable 501 respectively, and the hinge point between the connecting member 503 and the turntable 501 is eccentric to the central axis 502.

[0095] With this arrangement, a crank sliding structure can be formed by the sliding member 42, the connecting member 503 and the turntable 501. By driving the sliding member 42 up and down on the rod body 1, the turntable 501 can be driven to rotate accordingly, which makes it convenient for users to operate on the rod body 1 and avoids squatting or turning the rod body 1 upside down to adjust the turntable 501, thereby improving the user experience.

[0096] Preferably, the slider 42 is sleeved on the outside of the rod body 1. The user can directly contact the slider 42 for manipulation, further improving the convenience of manual control of the drive unit. As an alternative embodiment, when the rod body 1 is hollow, the slider 42 can be disposed inside the rod body 1, or partially inside the rod body 1.

[0097] In this embodiment, the sliding member 42 includes a sliding sleeve and a connecting rod. The number of sliding sleeves can be set accordingly as needed, specifically two or more. A gripping body is provided on the sliding sleeve away from the cleaning head, on which the user can manually control the gripping body to drive the entire sliding member 42 to slide along the rod body 1. The sliding sleeve relatively close to the cleaning head is hinged to the turntable 501 through a connecting member 503. The connecting member 503 is specifically a hard rod. At least two connecting rods are distributed circumferentially along the rod body 1, respectively connecting each sliding sleeve.

[0098] In this embodiment, the limiting device includes a spring 12 and a groove 421 that cooperates with the spring 12. One of the spring 12 and the groove 421 is provided on the slider 42, and the other is provided on the rod 1. When the spring 12 is located in the groove 421, the spring 12 and the groove 421 cooperate to limit the sliding of the slider 42 relative to the rod 1.
