[0052] 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.

[0053] Example 1

[0054] like Figure 1-Figure 3 The utility model provides a cleaning device with a preset cleaning position, comprising: a rod body 1, a cleaning head 2 and a driving unit.

[0055] 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 2 can be provided with additional structures such as a hook.

[0056] At least two cleaning members 21 are distributed on the cleaning head 2. The distribution position of the cleaning members 21 on the cleaning head 2 can be adjusted as needed, so that they can move to the preset cleaning position. The cleaning members 21 in the preset cleaning position are suitable for cleaning the object to be cleaned. It is understandable that three or more cleaning members 21 can be provided on the cleaning head 2.

[0057] Specifically, the cleaning member 21 can be one of a wiping cloth, a scraping strip, and a brush plate. An example is given below in which one of the cleaning members 21 is a wiping cloth and the other cleaning member 21 is a scraping strip.

[0058] like Figure 1 As shown, the user generally uses the cleaning head 2 to clean the cleaning member 21 away from the rod body 1, such as Figure 1 The position at the bottom of the cleaning device corresponds to the preset cleaning position in this embodiment.

[0059] When cleaning glass, users typically scrub the glass clean before scraping off any remaining water stains. Therefore, when using the cleaning device provided in this embodiment, the drive unit first drives the cleaning head 2 to rotate relative to the rod body 1, causing the two cleaning members 21 to move relative to the cleaning head 2, thereby switching one of the cleaning members 21 (the wiping cloth) to a preset cleaning position. Then, the user grips the rod body 1 to scrub the glass with the cleaning member 21 (the wiping cloth). When scrubbing is complete, the drive unit switches the cleaning member 21 (the scraping bar) to the preset cleaning position, allowing the cleaning member 21 (the scraping bar) to scrape off any remaining water stains.

[0060] The driving unit includes a driving member 4 and a transmission member 5. The driving member 4 is movably provided on the rod body 1. The transmission member 5 is respectively connected to the driving member 4 and the cleaning head 2. When the driving member 4 moves relative to the rod body 1, the cleaning head 2 is driven to move relative to the rod body 1 through the transmission member 5.

[0061] In this embodiment, the driving member 4 has an initial position. The driving member 4 moves a stroke relative to the rod body 1 and switches the cleaning member 21 at the preset cleaning position once. In this embodiment, the preset cleaning position is preferably arranged perpendicular to the rod body 1 to facilitate contact with the object to be cleaned. It can also be set to other relative positions with the rod body 1 as needed, such as a sixty-degree deflection, etc., to facilitate cleaning the object to be cleaned.

[0062] A stroke includes movement away from the initial position and movement back to the initial position.

[0063] At least two cleaning members 21 are respectively provided on the cleaning head 2, and cooperate with the driving unit to correspondingly drive the cleaning head 2 to move relative to the rod body 1 to realize the conversion of the two cleaning members 21, and then realize the adjustment of the cleaning members 21. The two cleaning members 21 can be specifically set according to the cleaning object on the member 21 to be cleaned or replaced after one of them is dirty, which effectively improves the user's experience. At the same time, the driving member 4 is set to switch the cleaning member 21 at a preset cleaning position once per single stroke, avoiding angular deviation in the free position or angle switching mode, and no adjustment correction is required, which further improves the user's experience.

[0064] In addition, a single stroke of the driving member 4 corresponds to switching the cleaning member 21 at a preset cleaning position once. A limiting device can be set only at the initial position of the driving member 4 to fix the driving member 4, so as to fix the cleaning member 21 through the driving member 4. The structure is simple and the cost is low.

[0065] Furthermore, since the cleaning head 2 will be contaminated by dirt during the cleaning process, if the cleaning head 2 is driven directly, the user's hands will be dirty. The driving member 4 is provided on the rod body 1, and drives the cleaning head 2 to rotate relative to the rod body 1 through the transmission member 5. The user does not need to touch the cleaning head 2, avoiding the risk of getting his hands dirty.

[0066] In this embodiment, the driving member 4 rotates one stroke relative to the rod body 1 in one direction to switch the cleaning member 21 at the preset cleaning position. Specifically, the one-way rotation means that when the driving member 4 rotates one full rotation relative to the rod body 1, the switching can be completed by rotating one full rotation clockwise or one full rotation counterclockwise; or the switching can be completed by alternating clockwise and counterclockwise rotations, each rotation being one full rotation each.

[0067] Such a setting of the movement mode of the driving member 4 relative to the rod body 1 is simple and easy to remember, and is convenient for the user to count the stroke of the driving member 4 and avoid adjusting the stroke to exceed the required corresponding cleaning member 21.

[0068] In this embodiment, the transmission member 5 includes a rotating disk 501, which is preferably a perfect circle, and its rotating shaft 502 is provided on the rod body 1. The rotating disk 501 is dynamically connected to the cleaning head 2 so that the rotating disk 501 is suitable for rotating relative to the rod body 1 under external force, thereby driving the cleaning head 2 to rotate.

[0069] The driving member 4 includes a gripping portion 41 provided on the rotating disk 501. The gripping portion 41 is eccentrically arranged with respect to the rotating shaft 502 and is suitable for driving the rotating disk 501 to rotate under the action of an external force, so as to drive the cleaning head 2 to move relative to the rod body 1; a stroke includes a rotation along the rotating shaft 502 relative to the rod body 1 away from the initial position and a rotation back to the initial position.

[0070] The gripping portion 41 is provided on the rotating disk 501 , and the rotating disk 501 can be directly driven to rotate by the gripping portion 41 , thereby driving the cleaning head 2 to rotate. The structure is stable, simple, and low in cost.

[0071] In this embodiment, a limiting device is provided on the rod body 1 to limit the movement of the driving member 4 relative to the rod body 1 .

[0072] 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 rotating disk 501 can be locked, thereby locking the rotation of the cleaning head 2, and then controlling the cleaning member 21 on the cleaning head 2 to correspond to the preset cleaning position, so as to facilitate the user to achieve cleaning.

[0073] 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 rotating shaft 502, so that the first clamping member 11 and the second clamping member 411 have a clamping position and an unlocking position.

[0074] In this embodiment, the grip portion 41 is mounted on the turntable and adapted to move axially along the rotation axis 502. Specifically, a grip shaft is provided on the inner side of the grip portion 41 and connected to the turntable. The grip shaft is eccentric relative to and parallel to the rotation axis 502. The grip portion 41 can rotate relative to the grip shaft, thereby enabling the grip portion 41 to drive the turntable to rotate under the action of an external force. Preferably, the grip portion 41 is disposed along the side of the turntable facing away from the rod body 1. Specifically, the grip portion 41 can move axially along the grip shaft, thereby enabling relative movement of the first clamping member 11 and the second clamping member 411 along the axial direction of the rotation axis 502.

[0075] The setting of the grip portion 41 can not only serve as a force-bearing structure for the user to manually drive the turntable 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 and improving the convenience of operation.

[0076] 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 rotating shaft 502 , or both can be movably arranged along the axial direction of the rotating shaft 502 .

[0077] 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.

[0078] 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 and parallel to the turntable 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.

[0079] In this embodiment, the number of cleaning members 21 on the cleaning head 2 is three. As a convertible embodiment, the number of cleaning members 21 can be two or more. Further preferably, the cleaning head 2 is rotatably connected to the rod body 1.

[0080] When there are two cleaning members 21, the cleaning head 2 and the rod body 1 can be connected in a swinging manner, and a single stroke of the driving member 4 can drive the cleaning head 2 to swing by a preset angle. Preferably, the preset angle is the angle between the two cleaning members 21. As a further alternative embodiment, when the cleaning members 21 are not completely densely distributed on the cleaning head 2 along the circumference, for example, the cleaning members 21 are only distributed on half of the outer circumference of the cleaning head 2, the cleaning head 2 and the rod body 1 can be connected in a swinging manner.

[0081] When the number of the cleaning members 21 is three or more, the cleaning head 2 and the rod body 1 are both rotatably connected, and the cleaning head 2 rotates relative to the rod body 1 in a directional manner.

[0082] The directional rotation setting can, on the one hand, simplify the user's operating actions and improve the user 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 each cleaning part 21, it is also convenient for the manufacturer to promote and try out different cleaning parts 21. If the user has a preferred preference, it can also be achieved by adjusting the shape of the cleaning head 2, limiting the number of cleaning surfaces on the cleaning head 2, and setting the cleaning surface and the cleaning part 21 to be detachable.

[0083] Specifically, a one-way limiting mechanism is provided between the cleaning head 2 and the rod body 1, and is used to limit the directional rotation of the cleaning head 2 relative to the rod body 1. Preferably, the one-way limiting mechanism is a ratchet mechanism, which is not shown in the figure. As an alternative embodiment, the one-way limiting mechanism can be a one-way needle bearing or other structure.

[0084] In this embodiment, the cleaning head 2 is plate-shaped, and at least two cleaning members 21 are distributed around the circumference of the cleaning head 2. The cleaning members 21 may also partially extend onto the plate surface. As an alternative embodiment, the cleaning head 2 may also be wheel-shaped, columnar, block-shaped, or a combination or variation of these shapes. The cleaning head 2 is rotatably connected to the rod body 1, so that the cleaning head 2 can drive the at least two cleaning members 21 to rotate relative to the rod body 1 along the circumference of the cleaning head 2. When the driving member 4 moves relative to the rod body 1, the driving member 5 drives the cleaning head 2 to rotate relative to the rod body 1.

[0085] When the number of cleaning elements 21 is three or more, the cleaning head 2 is rotatably connected to the rod body 1, and the cleaning head 2 rotates in a directional manner relative to the rod body 1, preferably, multiple cleaning elements 21 are evenly distributed in the circumference of the cleaning head 2; the driving element 4 moves a stroke relative to the rod body 1, the cleaning head 2 rotates unidirectionally relative to the rod body 1 once a preset angle, and the cleaning element 21 at the preset cleaning position is switched once.

[0086] This arrangement allows for a preset fixed angle to be traveled in a single stroke of the driving member 4, facilitating precise control of the correspondence between each cleaning member 21 on the cleaning head 2 and the preset cleaning position, thereby avoiding deviation. As an alternative embodiment, when the number of cleaning members 21 is three or more, the multiple cleaning members 21 can be unevenly distributed along the circumference of the cleaning head 2, with the spacing between the cleaning members 2 being evenly distributed.

[0087] Preferably, the cleaning head 2 is arranged in a triangular shape along the radial cross section, and the number of cleaning members 21 is three, and each cleaning member 21 is arranged on an edge of the triangle in a one-to-one correspondence, and the preset angle is 60°.

[0088] The triangular cross-section setting, on the one hand, makes the cleaning head 2 structure more stable and has higher structural strength; on the other hand, the number of the three cleaning surfaces is relatively balanced, and the user can quickly adjust to the required cleaning parts 21, and the number of cleaning parts 21 is suitable for the user's common usage scenarios.

[0089] Specifically, the three cleaning members 21 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 clean 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.

[0090] As a convertible embodiment, the cleaning head 2 can also be provided in the form of a quadrilateral plate, a pentagonal plate, etc.

[0091] In this embodiment, the driving unit indirectly drives the cleaning head 2 via the rotating shaft 3. The rotating shaft 3 and the cleaning head 2 can be integrally provided or independent of each other. When integrally provided, the rotating shaft 3 rotates in conjunction with the rod body 1. When independent of each other, the rotating shaft 3 is fixed to the rod body 1 and rotates in conjunction with the cleaning head 2. In this embodiment, a first gear member 6 is provided on the rotating shaft 3, and a second gear member 7 is mounted on the rotating disk 501. The two gear members mesh with each other to achieve transmission.

[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] The driving member 4 also includes a sliding member 42, which is dynamically connected to the cleaning head 2 via a connecting member 503. The sliding member 42 is slidably arranged on the rod body 1, and a stroke includes the sliding member 42 sliding away from the initial position and sliding close to the initial position along the axial direction of the rod body 1. The driving member 4 is provided with a sliding member 42, and a single reciprocating motion thereof along the axial limit of the rod body 1 is a stroke, corresponding to a single switching of the cleaning member 21, which is convenient for the user to count and use. Preferably, the axial motion stroke distance of the sliding member 42 along the rod body 1 can be adjusted as needed. It is understandable that when the sliding member 42 includes a gear and a rack form, a single stroke can also be a gear rotating forward and backward along the circumference of the rod body 1 for one week.

[0095] In this embodiment, the slider 42 is sleeved onto the rod body 1 and positioned externally thereto. The user can directly contact the slider 42 for manipulation, further enhancing the convenience of manually controlling the drive unit. Preferably, as a convertible embodiment, when the rod body 1 is hollow, the slider 42 can be positioned within the rod body 1, or partially within the rod body 1.

[0096] In this embodiment, the driving unit also includes a driving member 4, a transmission member 5, a rotating disk 501 and a limiting device.

[0097] Specifically, the driving member 4 includes a rotating disk 501 and a connecting member 503. The central axis of the rotating disk 501 is arranged on the rod body 1. The rotating disk 501 is dynamically connected to the cleaning head 2. The two ends of the connecting member 503 are respectively hinged to the sliding member 42 and the rotating disk 501, and the hinge point of the connecting member 503 and the rotating disk 501 is eccentrically arranged with the central axis, so that the sliding member 42 drives the rotating disk 501 to rotate through the connecting member 503, thereby driving the cleaning head 2 to move relative to the rod body 1.

[0098] With this arrangement, a crank sliding structure can be formed by the sliding member 42, the connecting member 503 and the rotating disk 501. By driving the sliding member 42 up and down on the rod body 1, the rotating disk 501 can be driven to rotate accordingly, which is convenient for users to operate on the rod body 1 and avoids squatting or turning the rod body 1 to adjust the rotating disk 501, thereby improving the user experience.

[0099] 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 2, on which the user can manually manipulate 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 2 is hinged to the rotating disk 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.

[0100] In this embodiment, the limiting device includes a spring 12 and a groove 421 that cooperates with the spring 12.
