Description

Technical Field

[0001] This utility model belongs to the technical field of mop-type cleaning tools, and specifically refers to a cleaning tool. Background Technology

[0002] Mops are the main tool for cleaning floors in daily life, while long-strip mops are tools that use strips of cotton cloth or long strips of cotton yarn fixed to the mop head for cleaning. Traditional long-strip mops usually use a centrifugal rotation method for washing and wringing.

[0003] For example, Chinese patent CN201110188805X discloses a cleaning tool, comprising: a mop bucket and a mop; a mop head with a wiping agent is provided at the lower end of the mop handle, the mop handle includes an inner rod and an outer rod, and a drive mechanism is provided between the inner and outer rods; the drive mechanism converts the extension and retraction motion of the mop handle into the rotational motion of the mop head; a rotatable spin-dry basket is provided in the mop bucket. The drive mechanism and the control mechanism constitute a variable speed drive mechanism; the drive mechanism includes: a one-way transmission mechanism between the inner and outer rods; when spin-drying, pressing down the mop handle, the drive mechanism of the variable speed drive mechanism drives the mop head to rotate at a first rotational speed; when washing, pressing down the mop handle at the same speed, the variable speed drive mechanism drives the mop head to rotate at a second rotational speed, and the first rotational speed is greater than the second rotational speed; the spin-dry basket and the washing head are located in the same mop bucket or the spin-dry basket and the washing head are located in different mop buckets. This product slows down the mop head during washing, making it easier for users. However, it also has some shortcomings: the mop head only has a one-way structure to prevent reverse rotation and there is no clutch. During the switching between the washing and spin-drying zones, there may be a problem of slowing down or getting stuck, which affects the user experience. Summary of the Invention

[0004] The purpose of this invention is to provide a cleaning tool with a deceleration structure.

[0005] The purpose of this utility model is achieved as follows:

The spin-drying area has a water-spinning basket, and the washing area has a support base. The mop includes a mop handle and a mop head. The mop head has a reduction mechanism and a central insertion hole. The water-spinning basket and the support base both have support columns at their upper ends, which can be inserted into the insertion hole. The reduction mechanism includes a cover and a center seat. The cover is rotatably mounted on the mop head or the center seat, forming a cavity between the cover and the mop head. The center seat is rotatably mounted in the center of the mop head and located in the center of the cavity. The side of the center seat has an external toothed surface, and the inside of the cover has an internal toothed surface. At least two planetary gears mesh between the external and internal toothed surfaces, and the shafts of the planetary gears are fixed to the mop head. The mop handle has a spiral rod drive device connected to the center seat and providing power for the rotation of the center seat.

[0007] The central seat has a cavity in the middle, and the cover has a hole in the middle that communicates with the cavity. A movable part is installed in the cavity. When the movable part is engaged with the cover, the central seat and the cover rotate synchronously. When the movable part is separated from the cover, the central seat and the cover are connected by a planetary gear.

[0008] The support column of the cleaning zone can pass through the hole and enter the cavity. The support column of the cleaning zone can lift the movable part to separate the movable part from the cover. The support column can engage the cover, and the cover cannot rotate around the support column. The support column of the water-spinning basket can pass through the hole and enter the cavity. The support column of the water-spinning basket cannot lift the movable part. The movable part is engaged with the cover. The support column can engage the cover, and the cover cannot rotate around the support column.

[0009] Furthermore, the concave cavity is provided with guide grooves / guide ribs on its side, and the movable part moves along the guide grooves / guide ribs. The movable part can only move up and down by relying on the inner wall of the concave cavity.

[0010] Furthermore, a first tooth is provided below the side wall of the movable part, and a second tooth is provided on the cover to engage with the first tooth; under the action of gravity, the movable part is in a low position, and the first tooth and the second tooth engage.

[0011] Furthermore, the first and second teeth are attached to the side of the cavity, and the engagement and disengagement of the first and second teeth do not affect the entry and exit of the support column.

[0012] Furthermore, an annular recess is provided at the bottom of the cavity, and a raised edge is provided above the movable part, the raised edge and the annular recess being adapted to each other.

[0013] Furthermore, the cap includes a first cap body and a second cap body that are fixed to each other. The first cap body and the second cap body are connected to form an annular groove.

[0014] Furthermore, the first cover is provided with a plurality of buckles, and the second cover is provided with a groove that engages with the buckles.

[0015] Furthermore, the lower periphery of the support column is provided with several protruding ribs, and the inner side of the hole of the cover is provided with a groove that mates with the protruding ribs; the protruding ribs do not contact the moving parts or the protruding ribs do not affect the up-down movement and rotation of the moving parts.

[0016] Furthermore, the movable part is provided with a recessed portion that mates with the support column.

[0017] The mop head is provided with annular ribs on its periphery, which are used to fix the wiping material.

[0018] The outstanding and beneficial technical effects of this utility model compared to the prior art are:

[0019] 1. This utility model features an independent movable component as a clutch. During washing, the support column of the washing area can lift the movable component, thus separating it from the cover. The central seat cannot drive the cover to rotate; the cover is locked by the support column of the washing area and cannot rotate. The rotating central seat drives the mop head to rotate via planetary gears. During spin-drying, the support column of the spin-dry basket cannot lift the movable component; the movable component is locked on the cover. The central seat drives the cover to rotate synchronously. The cover is locked by the support column of the spin-dry basket and cannot rotate. The rotating central seat drives the spin-dry basket to rotate. This clutch design makes control more precise, especially during the switching between washing and spin-drying, reducing the likelihood of jamming and improving the user experience.

[0020] 2. The cap of this utility model is divided into a first cap body and a second cap body that are interlocked with each other. The connection between the first cap body and the second cap body forms an annular groove. The lower end of the center seat has a skirt, which is limited in the annular groove. This structure allows the cap and the center seat to be rotatably connected. Furthermore, the first cap body and the second cap body adopt a scheme of multiple buckles and slots for connection, making the cap more stable. This structure also makes the assembly of the cap simpler for workers. First, place the center seat on the first cap body, and then align and clamp the first cap body and the second cap body.

[0021] 3. In this invention, the movable part is confined within the cavity. Under the influence of gravity, the movable part is in a low position, and the first and second teeth mesh, resulting in a simple structure. Furthermore, the first and second teeth are close to the side of the cavity, and their engagement and disengagement do not affect the entry and exit of the support column. The movable part will not interfere with the support column, making the structure more reasonable and less prone to jamming. Attached Figure Description

Detailed Implementation

[0034] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Figure 1-11 As shown:

[0035] A cleaning tool includes a mop bucket 1 and a mop. The mop bucket 1 has a spin-drying area and a washing area. The spin-drying area has a water-spinning basket 11, and the washing area has a support base 12. The water-spinning basket is in a higher position, and the support base is in a lower position. The mop includes a mop handle 29 and a mop head 2. The mop head 2 has a speed reduction mechanism and an insertion hole in the middle. The water-spinning basket and the support base both have support posts 111 at their upper ends. The support posts 111 can be inserted into the insertion hole, which is the hole 40 of the cover described below and the movable part. The component has a central recessed portion; the deceleration mechanism includes a cover 4 and a center seat 3. The cover 4 is rotatably mounted on the mop head 2 or the center seat 3, and a cavity is formed between the cover 4 and the mop head 2. The center seat 3 is rotatably mounted in the middle of the mop head and located in the middle of the cavity. The side of the center seat 3 is provided with an external tooth surface 34, and the inner side of the cover 4 is provided with an internal tooth surface 44. At least two planetary gears 6 mesh between the external tooth surface 34 and the internal tooth surface 44. The rotating shaft 21 of the planetary gears is fixed or integrally formed on the mop head 2. The mop handle 29 is equipped with a twisted rod drive device, which is connected to the center seat and provides power for the center seat to rotate. This application does not specify or describe the twisted rod drive device. This structure is a common part or outsourced part on the market. The dimensions can be provided to the outsourcing factory for procurement and installation. This structure can refer to the twisted rod structure in existing patents such as CN201110188805X, CN201010180839X, and CN2010101808436. As long as the center seat can be rotated by the twisted rod drive device, it is acceptable. The center seat 3 has a recess 30 in its middle, and the cover 4 has a hole 40 in its middle that communicates with the recess. A movable part 5 is installed inside the recess 30. When the movable part 5 engages with the cover 4, the center seat 3 and the cover 4 rotate synchronously. When the movable part 5 separates from the cover 4, the center seat 3 and the cover 4 are connected by a planetary gear 6. The movable part 5 acts as a clutch, controlling whether the center seat and the cover rotate synchronously. A ring-shaped rib 28 is provided around the mop head to secure the cleaning material, which can be a cleaning cloth, cotton thread, or other common commercially available cleaning products.

[0036] When the mop needs washing: The support column of the washing area can pass through the hole and enter the recessed cavity. The support column can lift the movable part, thus separating the movable part from the cover. The support column can engage the cover, and the cover cannot rotate around the support column. When the central seat is driven to rotate, the central seat drives the mop head to rotate through the planetary gear. The wiping material fixed on the mop head rotates and is cleaned in the liquid inside the mop head. Due to the deceleration through the planetary gear, the user's washing process is more effortless. When the mop needs spinning: The support column of the spin basket can pass through the hole and enter the recessed cavity. The support column of the spin basket cannot lift the movable part, and the movable part engages with the cover. The support column can engage the cover, and the cover cannot rotate around the support column. When the central seat is driven to rotate, the central seat and the cover rotate synchronously. The central seat can cause the spin basket to rotate synchronously through the cover, thus achieving spin-drying.

[0037] The concave cavity 30 is provided with guide grooves / guide ribs on its side. The movable part 5 moves along the guide grooves / guide ribs, and the movable part can only move up and down by relying on the inner wall of the concave cavity. Figure 9 As shown, the movable part 5 is provided with a guide groove 53, and the guide ribs in the cavity are not shown in the attached drawing.

[0038] The movable part 5 has a first tooth 52 on its lower side wall, and the cover 4 has a second tooth 42 that engages with the first tooth 52. Under the action of gravity, the movable part 5 is in a low position, and the first tooth 52 and the second tooth 42 are engaged. Furthermore, the first tooth 52 and the second tooth 42 are close to the side of the cavity 30. The engagement and disengagement of the first tooth and the second tooth do not affect the entry and exit of the support column 111, and the movable part 5 will not interfere with the support column 111, making the structure more reasonable and less prone to jamming.

[0039] The bottom of the cavity 30 is provided with an annular recess 31, and the upper part of the movable member 5 is provided with a raised edge 51, which is adapted to the annular recess 31. This structure is used to position the movable member 5, reducing shaking after the movable member 5 is separated from the cover 4, and making it more stable during rotation.

[0040] The cap 4 includes a first cap body 4a and a second cap body 4b that are fixed to each other. The connection between the first cap body 4a and the second cap body 4b forms an annular groove 49. The lower end of the center seat 3 has a skirt 39, which is confined within the annular groove 49. With the connection between the skirt and the annular groove, the cap is rotatably mounted on the center seat. This structure allows the cap and the center seat to be rotatably connected. Furthermore, the first cap body 4a and the second cap body 4b are connected by multiple snap fasteners 43 and slots 45, making the cap more stable. This structure also simplifies assembly for workers; they can first place the center seat on the first cap body, and then align and clamp the first and second cap bodies.

[0041] The lower end of the support column 111 is provided with a number of protruding ribs 112, and the inner side of the hole 40 of the cover is provided with a groove 41 that cooperates with the protruding ribs 112. This structure fixes the support column 111 and the cover 4 together. The protruding ribs do not contact the moving parts or do not affect the up-down movement and rotation of the moving parts.

[0042] The movable part 5 is provided with a recess 59 that mates with the support column 111.

[0043] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model.
