Description

Technical Field

[0001] The present invention relates to the technical field of cleaning tools, and particularly relates to a mop cleaning device and a lifting structure. Background Art

[0002] As a common cleaning tool, the mop is simple and inexpensive, has strong decontamination ability, and is an essential tool at home. However, it is difficult to clean the mop after use and often requires manual cleaning. To solve the problem of inconvenient manual cleaning, a mop bucket configured to cooperate with the mop is usually provided at home for effectively cleaning the mop.

[0003] To meet the need for dehydrating the mop, a water filter basket is also provided in the mop bucket in the prior art. By adjusting the staying height of the water filter basket in the mop bucket, the mop in the water filter basket can be switched between the immersed state and the water-off state, ensuring the realization of the cleaning and dehydration functions. However, in the prior art, for example, in the patent document with the publication number CN211484425U, a lifting cleaning tool is disclosed. The limiting structure or locking structure in the mop bucket needs to respectively limit the water filter basket at different staying heights, which is realized through an elastic limiting structure in cooperation with a guiding structure with a complex shape. On the one hand, there are many components, the structure is complex, production and assembly are inconvenient, and the cost is relatively high. On the other hand, when the user adjusts the height of the water filter basket, the force required to disengage the limit is relatively large, which is inconvenient to use and reduces the user experience.

[0025] The technical solution of the present invention has the following advantages:

[0026] 1. The present invention provides a mop cleaning device, including: a first container suitable for containing water; a supporting device arranged in the first container, suitable for carrying a mop, and moving up and down along the depth direction of the first container under the action of an external force, and having a cleaning position closely adjacent to the bottom of the first container and a dehydration position far from the bottom of the first container along the depth direction; a lifting structure, including: a guiding member arranged along the height direction; a guiding and cooperating member movably connected with the guiding member, suitable for moving along the guiding member under the action of an external force; a guiding and limiting member arranged on the guiding and cooperating member and movably connected with the guiding and cooperating member, suitable for rotating relative to the guiding and cooperating member under the action of gravity and the force applied by the guiding and cooperating member, and having a positioning state of rotating to be limitedly connected with the guiding member, and an adjusting state of rotating under the action of gravity and the force applied by the guiding and cooperating member and disengaging from the positioning state; when the guiding and limiting member rotates to the positioning state, the lifting structure is suitable for limiting the supporting device to the dehydration position, and when the guiding and limiting member rotates to the adjusting state, the lifting structure is suitable for releasing the limitation of the supporting device and enabling it to slide to the cleaning position.

[0027] A lifting structure including a guide member, a guide matching member and a guide limiter is provided. On the one hand, the guide matching member and the guide member are respectively provided on the support device and the first container, and the guide member is provided along the depth direction. When the support device is connected with the mop and bears the lifting and releasing force from the user of the mop, the support device performs lifting and lowering movement along the depth direction of the first container. At the same time, water is stored in the first container, and the support device can carry the mop and pass through the water body. During the lifting process, the support device switches between the state of being immersed in water and being out of water, so as to facilitate the cleaning and dehydration of the mop.

[0028] On the other hand, the guide limiter is arranged on the guide fitting part and is movably connected with each other, so that when the supporting device makes a lifting and lowering movement along the depth direction of the first container, the guide fitting part moves up and down synchronously along the guide fitting part. When the guide fitting part moves along the guide fitting part, the guide limiter on the guide fitting part swings or rotates under the action of the lifting and lowering driving force and its own gravity, thereby adjusting the relative position of the guide limiter itself and the guide fitting part, thereby realizing the conversion between the positioning state of mutual limitation and the adjustment state of separation from the limitation with the guide fitting part, and adjusting the position conversion of the supporting device between the cleaning position and the dehydration position.

[0029] Such an arrangement can satisfy the cleaning and dehydrating functions of the mop, and further, the guide limit member can rotate under the lifting driving force and its own gravity, so as to satisfy the limitation and disengagement with the guide member and adjust the position of the supporting device. When the user lifts and places the supporting device, there is no need to overcome other resistances caused by the guide limit member, so the operation is more labor-saving. Moreover, the guide member, guide matching member and guide limit member in the lifting structure are simple in structure, easy to implement, convenient to produce and assemble, and low in cost. Therefore, such an arrangement effectively overcomes the defects in the prior art that the mop bucket has many parts for limiting the water filter basket at different staying heights, the structure is complex, the production and assembly are inconvenient, the cost is high, and the user's force required to disengage the limit is large, which is inconvenient to use and reduces the user's experience.

[0030] 2. The mop cleaning device provided by the present invention comprises a limiting part comprising: a limiting snap-in, which is arranged on the outer edge of the limiting body. In the first limiting position, the limiting snap-in is rotated to face the guide member under the force of gravity and the guide fitting and is engaged and connected with the guide member; a limiting side edge, which is arranged on the outer edge of the limiting body and is adjacent to the limiting snap-in. In the second limiting position, the limiting snap-in is rotated to move away from the guide member under the force of gravity and the guide fitting and is spaced apart from the guide member respectively as well as the limiting snap-in.

[0031] By setting the limiting part to include a limiting bayonet and a limiting side edge, on the one hand, an open-shaped limiting bayonet is provided on the limiting main body as a rotating body, which facilitates locking or unlocking between the limiting structures by rotating in different directions, improves flexibility, and avoids jamming. On the other hand, the setting of the limiting side edge in cooperation with the limiting bayonet adjusts the shape of the limiting main body, enabling the limiting main body to have different rotation radii during rotation. It can not only cooperate with the limiting bayonet for locking or unlocking, but also prevent the guiding fitting from interfering with the guiding part when lifting is required.

[0032] 3. In the mop cleaning device provided by the present invention, the guiding and limiting part is arranged in the shape of a butterfly buckle, including two limiting bayonets and two limiting side edges. The two limiting bayonets are arranged oppositely, and the two limiting side edges are arranged oppositely.

[0033] With such a setting, the distribution uniformity of the limiting bayonet and the limiting side edge is improved, the angle required for the limiting bayonet on the limiting main body to be limit-connected to and disengaged from the guiding part is reduced, and the requirement for external force is lowered.

[0034] 4. The mop cleaning device provided by the present invention further includes: a limiting protrusion, which protrudes on the inner wall of the first container, is arranged above the guiding part along the depth direction, and clamps the guiding and limiting part with the guiding part. The limiting protrusion has a third limiting position for abutting and limiting with the limiting bayonet, and a fourth limiting position for abutting and limiting with the limiting side edge.

[0035] By arranging the limiting protrusion above the guiding part, the movement stroke of the guiding and limiting part can be limited, preventing the guiding fitting from disengaging from the guiding part, and thus avoiding the situation where the supporting device disengages from the first container. In addition, through the setting of the limiting bayonet and the limiting side edge on the limiting part, with different rotation radii, they can be respectively limited at the third limiting position and the fourth limiting position with the limiting protrusion, and further adjust the relative height between the first container and the supporting device.

[0052] Embodiment 1

[0053] As Figure 1 - Figure 9 shown, this embodiment provides a mop cleaning device, including: a first container 1, a support device 2, and a lifting structure.

[0054] Among them, the first container 1 is in a cylindrical shape and is suitable for containing water. In this embodiment, a drain port and a drain switch are provided at a position near the bottom surface of the side wall of the first container 1. The drain switch can be a plug or can be threadedly connected to the drain port. A collar is also provided at the top end of the first container 1, as well as a semi-circular handle movably connected to the first container 1.

[0055] The supporting device 2 is arranged in the first container 1. Its specific shape is not limited and can be plate-shaped or basket-shaped, etc. It can accommodate the mop and pass through the water. In addition, the supporting device 2 can be raised and lowered along the depth direction of the first container 1 under the force of the mop or other external forces, and has a cleaning position close to the bottom of the first container 1 and a dehydration position away from the bottom of the first container 1 along the depth direction. Specifically, in the cleaning position, the mop on the supporting device 2 is immersed in the water in the first container 1, and in the dehydration position, the supporting device 2 is away from the bottom of the first container 1. In addition, the specific heights of the cleaning position and the dehydration position can be one or more.

[0056] The lifting structure comprises: a guide member 3, a guide matching member 4 and a guide limiting member 5.

[0057] The guide member 3 is arranged along the height direction, and the guide matching member 4 is movably connected to the guide member 3 and is suitable for moving along the guide member 3 under the action of external force. In the present embodiment, the guide matching member 4 is a structure that moves up and down with the external force, and a guide limit member 5 is arranged on it. Furthermore, the guide matching member 4 is arranged in the shape of a slider in the present embodiment, and the guide member 3 is arranged in the shape of a guide rail. As a convertible implementation method, the guide matching member 4 can be arranged in the shape of a guide rail, and the guide matching member 4 can be arranged in the shape of a slider.

[0058] The guide limit member 5 is arranged on the guide fitting member 4 and is movably connected with the guide fitting member 4. It is suitable for rotating relative to the guide fitting member 4 under the force of gravity and the guide fitting member 4, and has a positioning state in which it rotates to be limitedly connected with the guide member 3, and an adjustment state in which it rotates under the force of gravity and the guide fitting member 4 and is separated from the positioning state; when the guide limit member 5 rotates to the positioning state, the lifting structure is suitable for limiting the support device 2 to the dehydration position, and when the guide limit member 5 rotates to the adjustment state, the lifting structure is suitable for releasing the limit support device 2 and making it slide to the cleaning position.

[0059] A lifting structure including a guide member 3, a guide matching member 4 and a guide stopper 5 is provided. On the one hand, the guide matching member 4 and the guide member 3 are respectively provided on the support device 2 and the first container 1, and the guide member 3 is provided along the depth direction. When the support device 2 is connected to the mop and carries the lifting and releasing force from the user of the mop, the support device 2 performs lifting and lowering movement along the depth direction of the first container 1. At the same time, the first container 1 stores water, and the support device 2 can carry the mop and pass through the water. During the lifting process, the support device 2 switches between the state of being immersed in water and being out of water, so as to facilitate the cleaning and dehydration of the mop.

[0060] On the other hand, the guiding and limiting member 5 is arranged on the guiding and cooperating member 4 and is movably connected to each other. When the supporting device 2 moves up and down along the depth direction of the first container 1, the guiding and cooperating member 4 moves up and down synchronously along the guiding member 3. When the guiding and cooperating member 4 moves along the guiding member 3, the guiding and limiting member 5 on the guiding and cooperating member 4 swings or rotates under the action of the lifting driving force and its own gravity, so as to adjust the relative position between the guiding and limiting member 5 itself and the guiding member 3, and further realize the conversion between the positioning state of mutual limiting and the adjusting state of disengaging from the limit with the guiding member 3, and adjust the position conversion of the supporting device 2 between the cleaning position and the dehydration position.

[0061] With such a setting, while meeting the functions of cleaning and dewatering the mop, further, the guiding and limiting member 5 rotates under the action of the lifting driving force and its own gravity, so as to meet the limiting and disengaging from the limit with the guiding member 3, and adjust the position of the supporting device 2. When the user lifts and places the supporting device 2, there is no need to overcome other resistances brought by the guiding and limiting member 5, and the operation is more labor-saving. Moreover, the guiding member 3, the guiding and cooperating member 4 and the guiding and limiting member 5 in the lifting structure are simple in structure and easy to implement, convenient for production and assembly, and low in cost. Therefore, such a setting effectively overcomes the defects in the prior art that there are many components for the water filtering basket 21 in the mop bucket to be respectively limited or locked at different staying heights, the structure is complex, inconvenient for production and assembly, high in cost, and the force applied by the user required to disengage from the limit is large, inconvenient to use, and reduces the user experience.

[0062] In this embodiment, the guiding member 3 is arranged on the inner wall of the first container 1 and extends along the depth direction. The guiding and cooperating member 4 is arranged on the supporting device 2, cooperates with the guiding member 3 and is slidably connected to each other. The guiding and cooperating member 4 is adapted to move up and down relative to the guiding member 3 under the force applied by the supporting device 2, and drive the guiding and limiting member 5 to rotate relatively and switch between the positioning state and the adjusting state.

[0063] As a transformable implementation manner, a sleeve structure is further arranged at the bottom of the first container 1. The guiding member 3 is arranged on the inner wall of the sleeve structure, or can also be arranged on its outer wall. The guiding member 3 extends along the depth direction. The guiding and cooperating member 4 is arranged at the bottom of the supporting device 2 and is slidably connected to the guiding member 3. The guiding and cooperating member 4 is adapted to move up and down relative to the guiding member 3 under the force applied by the supporting device 2, and drive the guiding and limiting member 5 to rotate relatively and switch between the positioning state and the adjusting state. In addition, as another transformable implementation manner, the sleeve structure can also be not provided, and only the guiding member 3 is arranged on the bottom of the first container 1.

[0064] In this embodiment, the guiding and limiting member 5 includes a limiting main body 51 and a limiting portion 52.

[0065] The specific shape of the limiting main body 51 is not limited, as long as it can be arranged on the guiding and fitting member 4 and is movably connected to the guiding and fitting member 4, and has a positioning state and an adjusting state. In this embodiment, preferably, the limiting main body 51 is plate-shaped, and a connecting shaft portion 511 is arranged in the middle thereof. The connecting shaft portion 511 is movably connected to the guiding and fitting member 4. Specifically, in this embodiment, the guiding and fitting member 4 as a groove body is provided with a convex shaft on the groove bottom facing the guiding member 3. The connecting shaft portion 511 is limitedly sleeved on the convex shaft and can rotate along the convex shaft under the action of gravity and the force applied by the guiding and limiting member 5.

[0066] The limiting portion 52 is arranged on the outer edge of the limiting main body 51. In the positioning state, the limiting portion 52 has a first limiting position that is engaged and connected with the guiding member 3, and limits the supporting device 2 to the dehydration position. In the adjusting state, the limiting portion 52 has a second limiting position that avoids the guiding member 3 and is adjacent to the inner bottom surface of the first container 1, and limits the supporting device 2 to the cleaning position. By setting the second limiting position adjacent to the inner bottom of the first container 1, at this time, the supporting device 2 and the mop thereon can be immersed in the water in the first container 1.

[0067] The first limiting position is higher than the second limiting position in the depth direction and is adapted to be separated from the water body in the first container 1. By separating from the water body in the first container 1, the mop accommodated in the supporting device 2 can be dehydrated by means such as standing still or rotating. The limiting portion 52 can be switched between the first limiting position and the second limiting position under the action of the limiting main body 51.

[0068] In this embodiment, the limiting main body 51 can rotate relative to the convex shaft, and the external force driving the rotation of the limiting main body 51 is specifically the resultant force of the driving force applied by the user on the top side of the supporting device 2 through the mop and the vibration of the gravity of the limiting portion 52. As an alternative implementation, a structure such as a motor can be connected to the convex shaft, and the limiting portion 52 is driven to rotate by the driving force of the motor.

[0069] Specifically, the limiting portion 52 includes: a limiting bayonet 521 and a limiting side edge 522.

[0070] The limiting bayonet 521 is arranged in an open shape on the outer edge of the limiting main body 51. In the first limiting position, the limiting main body 51 rotates under the action of an external force, and the limiting bayonet 521 can rotate towards the direction of the guiding member 3 and is engaged and connected with the guiding member 3 to realize the positioning of the first container 1 and the supporting device 2. In addition, the limiting side edge 522 is straight and is also arranged on the outer edge of the limiting main body 51, adjacent to the limiting bayonet 521.

In addition, through the setting of the limiting bayonet 521 and the limiting side edge 522 on the limiting portion 52, with different rotation radii, they can be respectively limited with the limiting protrusion 6 at the third limiting position and the fourth limiting position, and further adjust the relative height between the first container 1 and the support device 2.

[0091] Embodiment 2

[0092] The present invention further provides a lifting structure, including: a guiding member 3, a guiding mating member 4, and a guiding limiting member 5.

[0093] The guiding member 3 is arranged along the height direction. The guiding mating member 4 is movably connected to the guiding member 3 and is adapted to move along the guiding member 3 under the action of an external force. In this embodiment, the guiding mating member 4 is a structure that moves up and down with the external force, and a guiding limiting member 5 is arranged thereon. Further, in this embodiment, the guiding mating member 4 can be arranged in a slider shape, and the guiding member 3 is arranged in a guide rail shape. As an alternative embodiment, the guiding mating member 4 can be arranged in a guide rail shape, and the guiding mating member 4 can be arranged in a slider shape.

[0094] The guiding limiting member 5 is arranged on the guiding mating member 4 and is movably connected to the guiding mating member 4. It is adapted to rotate relative to the guiding mating member 4 under the action of gravity and the force applied by the guiding mating member 4, and has a positioning state of rotating to be in limiting connection with the guiding member 3, and an adjusting state of rotating under the action of gravity and the force applied by the guiding mating member 4 and disengaging from the positioning state.

[0095] A lifting structure including a guiding member 3, a guiding mating member 4, and a guiding limiting member 5 is provided. The guiding limiting member 5 is arranged on the guiding mating member 4 and is movably connected to each other. The guiding mating member 4 moves up and down synchronously along the guiding member 3. When the guiding mating member 4 is subjected to an external force, it can move along the guiding member 3. The guiding limiting member 5 on the guiding mating member 4 swings or rotates under the action of the lifting driving force and its own gravity, thereby adjusting the relative position of the guiding limiting member 5 itself and the guiding member 3, and further realizing the conversion between the positioning state of mutual limiting with the guiding member 3 and the adjusting state of disengaging from the limit.

[0096] With such an arrangement, the guiding limiting member 5 rotates under the lifting driving force and its own gravity, which can satisfy the limiting and disengaging from the limit with the guiding member 3, and adjust the position of the supporting device 2. When the user lifts and lowers the guiding mating member 4, there is no need to overcome other resistances brought by the guiding limiting member 5, and the operation is more labor-saving. Moreover, the guiding member 3, the guiding mating member 4, and the guiding limiting member 5 in the lifting structure are simple in structure and easy to implement, convenient for production and assembly, and low in cost. Therefore, such an arrangement can overcome the defects of the prior art in the lifting structure, such as having more components in the limiting structure or locking structure for respectively limiting at different staying heights, complex structure, inconvenient production and assembly, high cost, large force required for disengaging from the limit, inconvenient use, and reduced user experience.

[0097] In this embodiment, the guiding limiting member 5 includes a limiting main body 51 and a limiting portion 52.

[0098] There is no limit to the specific shape of the limiting main body 51, as long as it can be arranged on the guiding and cooperating part 4 and is movably connected to the guiding and cooperating part 4, and has a positioning state and an adjusting state. In this embodiment, preferably, the limiting main body 51 is plate-shaped, and a connecting shaft part 511 is arranged in the middle thereof. The connecting shaft part 511 is movably connected to the guiding and cooperating part 4. Specifically, in this embodiment, as the guiding and cooperating part 4 in the form of a groove body, a convex shaft is arranged on the groove bottom facing the guiding part 3. The connecting shaft part 511 is limitedly sleeved on the convex shaft and can rotate along the convex shaft under the action of gravity and the force applied by the guiding and limiting part 5.

[0099] The limiting part 52 is arranged on the outer edge of the limiting main body 51. In the positioning state, the limiting part 52 has a first limiting position for engaging and connecting with the guiding part 3. In the adjusting state, the limiting part 52 has a second limiting position for avoiding the guiding part 3.

[0100] Specifically, the limiting part 52 includes: a limiting bayonet 521 and a limiting side edge 522.

[0101] The limiting bayonet 521 is arranged in an open shape on the outer edge of the limiting main body 51. In the first limiting position, when the limiting main body 51 rotates under the action of an external force, the limiting bayonet 521 can rotate towards the direction of the guiding part 3 and engage and connect with the guiding part 3. In addition, the limiting side edge 522 is straight and is also arranged on the outer edge of the limiting main body 51, adjacent to the limiting bayonet 521. In the second limiting position, the limiting bayonet 521 rotates away from the guiding part 3 under the action of gravity and the force applied by the guiding and cooperating part 4, and is spaced from the guiding part 3 respectively.

[0102] As a transformable implementation manner, in the second limiting position, the limiting side edge 522 can abut against the guiding part 3.

[0103] By arranging the limiting part 52 to include the limiting bayonet 521 and the limiting side edge 522, on the one hand, the open-shaped limiting bayonet 521 is arranged on the limiting main body 51 as a rotating body, which is convenient for locking or unlocking between the limiting structures by rotating in different directions, improves flexibility and avoids jamming. On the other hand, the setting of the limiting side edge 522 in cooperation with the limiting bayonet 521 adjusts the outer shape of the limiting main body 51, so that the limiting main body 51 has different rotation radii during rotation, which can not only cooperate with the limiting bayonet 521 for locking or unlocking, but also avoid interference between the guiding and cooperating part 4 and the guiding part 3 when lifting is required.

[0104] Specifically, the guiding and limiting member 5 is arranged in the shape of a butterfly buckle. Preferably, the limiting portions 52 thereon are symmetrically arranged, including two limiting buckles 521 and two limiting side edges 522. The two limiting buckles 521 are arranged oppositely, and the two limiting side edges 522 are arranged oppositely and parallelly. With such an arrangement, the distribution uniformity of the limiting buckles 521 and the limiting side edges 522 is improved, the angle required for the limiting buckles 521 on the limiting main body 51 to be connected and disengaged from the guiding member 3 is reduced, and the requirement for external force is reduced.

[0105] As a transformable implementation manner, multiple groups of limiting buckles 521 and limiting side edges 522, or a single group of limiting buckles 521 and limiting side edges 522, can be arranged on the guiding and limiting member 5.

[0106] In this embodiment, the guiding member 3 includes a first guide rail member and a second guide rail member arranged in parallel at intervals. A first limiting end 31 is arranged at the upper end of the first guide rail member along the depth direction of the first container 1. At the first limiting position, the first limiting end 31 is engaged with the limiting buckle 521. A second limiting end 32 is arranged at the upper end of the second guide rail member in the depth direction. At the first limiting position, the second limiting end 32 is arranged at an interval from the limiting side edge 522. At the second limiting position, the limiting portion 52 is clamped between the first guide rail member and the second guide rail member. As a transformable implementation manner, at the first limiting position, the second limiting end 32 and the limiting side edge 522 can be arranged in an abutting manner.

[0107] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made on the basis of the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
