A single-bucket lifting cleaning tool

Abstract

This invention discloses a single-bucket lifting cleaning tool, including a rotating basket that can be raised and lowered and can stop at a high and low position. The rotating basket can rotate along a vertical axis and includes a gear set that drives the rotation of the basket. The gear set can reciprocate along the lifting direction of the basket, and its raising and lowering allows it to engage during washing and disengage during dehydration. The reduced speed of the gear set achieves a labor-saving effect; the basket rotates slowly during washing, requiring less effort, and spins quickly during dehydration, while also requiring less effort due to the absence of water resistance. In addition, the lower rotation speed prevents water from splashing out due to excessive speed.

Description

Technical Field

[0001] This invention belongs to the field of cleaning products technology, and in particular relates to a single-bucket lifting cleaning tool. Background Technology

[0002] Among existing mops and mop bucket kits, there is a type of mop bucket that can be raised and lowered coaxially to achieve cleaning and wringing. This is accomplished by raising and lowering the mop. For example, Chinese utility model patent No. ZL201821379338.2 discloses a "self-lifting cleaning tool for cleaning mops with separate cleaning and dirty water", which is equipped with a lifting device that allows switching between high and low positions by manually lifting the mop. Another example is Chinese utility model patent No. ZL201820024081.2, which discloses a "self-lifting cleaning tool for mops", which also achieves switching between high and low positions by manually lifting the lifting device.

[0003] These types of mop buckets are used with flat mops. Their lifting stroke is short, requiring only a slight lift. However, for mops that wipe bundled or long bundles of material, the lifting mechanism mentioned above is insufficient. Therefore, the washing and wringing of this type of mop is generally accomplished using a dual-bucket system. For example, Chinese utility model patent number ZL201621098919.X discloses a water-circulating split mop bucket, which uses a dual-chamber structure for separate washing and wringing.

[0004] In addition, when washing a mop in water, it is difficult to press down and wash due to water resistance, and washing too fast will also cause water to splash. Summary of the Invention

[0005] The main technical problem solved by this invention is to provide a single-bucket lifting cleaning tool. The gear set reduces the speed to save effort. The rotating basket rotates slowly during washing, which saves effort, and it spins quickly during dehydration. At the same time, since there is no water resistance, it is also effortless. In addition, the low rotation speed can also prevent water from splashing out due to excessive speed.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A single-bucket lifting cleaning tool includes a rotating basket for washing and / or wringing a mop, the rotating basket being rotatably connected to the mop bucket, and the rotating basket being able to rise and fall and stop at a high position and a low position.

[0008] The rotating basket is capable of rotating along a vertical axis and also includes a gear set capable of driving the rotating basket to rotate, the gear set being capable of reciprocating along the lifting direction of the rotating basket;

[0009] When the rotating basket is in the low position, the gear set connects the rotating basket and / or the power source to drive the rotating basket to rotate, and the rotational speed of the rotating basket is equal to the output speed of the power source.

[0010] When the rotating basket rises to the high position, the gear set descends and disengages from the rotating basket and / or power source, so that the rotating basket is not driven by the gear set.

[0011] Furthermore, the mop is a push-down rotary mop or an electric rotary mop;

[0012] It also includes a drive column, which can be connected to the mop and driven to rotate by the mop, and the drive column constitutes the power source;

[0013] The drive column is rotatably connected to the rotating basket.

[0014] Furthermore, the mop head has a drive hole that connects with the drive post, and the drive hole and the drive post have a matching polygonal structure.

[0015] Furthermore, the mop head includes an inner disc and an outer disc. The inner disc is connected to the mop handle and can be driven to rotate by the mop handle. The outer disc is coaxially arranged with the inner disc and rotatably connected to the inner disc. The drive hole is located in the inner disc.

[0016] It also includes a linkage pin, which is located at the connection between the inner disk and the outer disk, and the linkage pin can move to lock the inner disk and the outer disk so that they rotate synchronously, or move to disengage from the lock so that the inner disk and the outer disk can rotate separately.

[0017] Furthermore, one end of the linkage pin extends out of the inner wall of the drive hole and can reciprocate in the direction of extension;

[0018] When the linkage pin is in its normal state, the inner plate and the outer plate rotate synchronously and locked together; when the extended part is retracted or partially retracted, the inner plate and the outer plate rotate separately.

[0019] The contact position between the outer disk and the rotating basket is also provided with a first tooth that enables the two to engage and rotate synchronously.

[0020] Furthermore, the drive column is rotatably connected to a rotating shaft fixed inside the mop bucket. The drive column can rotate around the rotating shaft and can slide back and forth along the axial direction of the rotating shaft.

[0021] The drive column and the rotating basket are provided with a second tooth that can engage, and the reciprocating sliding constitutes engagement or disengagement. When engaged, the drive column and the rotating basket stop rotating relative to each other. When disengaged, the drive column and the rotating basket separate and rotate.

[0022] When the rotating basket is in the low position, one end of the rotating shaft extends out of the end of the drive column;

[0023] When the rotating basket is in the high position, one end of the rotating shaft is retracted into the end of the drive column.

[0024] Furthermore, the rotating basket is rotatably connected to the lifting mechanism;

[0025] The gear set is slidably connected to the lifting mechanism, and the slidable connection is such that the gear set slides axially with the lifting mechanism and is circumferentially non-rotating.

[0026] Furthermore, the gear set is a planetary gear mechanism, which includes a sun gear, planet gears, an internal gear carrier, and a planet carrier;

[0027] The planetary gear mechanism, the drive column, and the rotating basket are coaxially arranged.

[0028] The sun gear and the drive column have a first ratchet that can mesh, and the planet carrier and the spool have a second ratchet that can mesh. The first ratchet and the second ratchet are located on the same side of the planetary gear mechanism.

[0029] Furthermore, the lifting mechanism includes a lifting frame having a cavity for the gear assembly to be inserted into;

[0030] The gear set is slidably connected to the cavity; the inner wall of the cavity and the gear set have a concave-convex structure to prevent them from rotating relative to each other.

[0031] Furthermore, the lifting mechanism includes a lifting frame connected to the mop bucket, the lifting frame being able to rise and fall along a preset path and stop at the high position and the low position, the preset path being provided on the mop bucket and / or the lifting frame, and the rotating basket being rotatably connected to the lifting frame;

[0032] It also includes a support mechanism for stopping the lifting frame at the high position, the support mechanism including a support column and a support block with a labyrinth slide;

[0033] The support block is slidably connected to the lifting frame or the mop bucket. When the support column slides into the maze slide, the support block can move to accommodate the sliding of the support column in the maze slide.

[0034] Furthermore, a limiting structure is also provided, which is used to limit the position of the support block during the lifting process of the lifting frame.

[0035] Furthermore, the lifting frame has a connecting part that connects to the mop bucket. The connecting part includes a hollow cavity, and the support block is placed in the cavity and can move linearly to accommodate the sliding of the support column within the maze slide.

[0036] Furthermore, the direction of movement of the support block is defined as direction A, and the cavity has through openings on opposite sides of direction A. When the support block slides within the cavity, its two sides can extend out from the openings.

[0037] The limiting structure is a blocking part provided on one or both sides of the support block. The blocking part can interfere with the protruding support block to limit the position of the support block.

[0038] Furthermore, the limiting structure includes protrusions on the inner wall of the mop bucket, the protrusions being arranged in pairs and located on both sides of the support block.

[0039] Furthermore, the height of the protrusion is less than the height of the lifting frame when it is in a high position;

[0040] The portion of the support block extending out of the opening has a sloping lower edge.

[0041] Furthermore, the preset path is a vertically arranged track, and the lifting frame can rise or fall vertically along the track.

[0042] Furthermore, the track includes a vertically arranged protrusion located on the inner wall of the mop bucket, and the lifting frame has a slot that can engage with the protrusion and slide along it.

[0043] The beneficial effects of this invention are:

[0044] The single-bucket lifting cleaning tool of the present invention achieves two functions: washing the mop in water and wringing it out of the water by lifting the rotating basket. When washing in water, the resistance of the water makes the washing process relatively strenuous. The present invention achieves a strenuous effect by reducing the speed through the gear set. That is, the rotating basket moves slowly during washing but requires less effort, and it moves quickly during wringing. At the same time, since there is no water resistance, it is also less strenuous. In addition, the lower rotation speed can also prevent water from splashing out due to excessive speed.

In order to better understand the technical means of the present invention and to implement it in accordance with the contents of the specification, the preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0067] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more explicit definition of the scope of protection of the present invention.

[0068] Example:

[0069] A single-bucket lifting cleaning tool, such as Figure 1 and Figure 2 As shown: Includes a rotating basket 3 for washing and / or wringing the mop 1, the basket being rotatably connected to the mop bucket 2, and the basket being able to rise and fall and stop at a high position and a low position; here, "high position" and "low position" are relative terms.

[0070] The rotating basket is rotatably connected to the lifting mechanism 10; the gear set is slidably connected to the lifting mechanism, and the slidable connection is such that the gear set slides axially with the lifting mechanism and is circumferentially non-rotating.

[0071] The rotating basket is capable of rotating along a vertical axis and also includes a gear set 20 capable of driving the rotating basket to rotate. The gear set is capable of reciprocating along the lifting direction of the rotating basket.

[0072] In this embodiment, the sliding mechanism of the gear set drives the rotating basket to rotate or disengages from the drive.

[0073] When the rotating basket is in the low position, the gear set connects the rotating basket and / or the power source to drive the rotating basket to rotate, and the rotational speed of the rotating basket is equal to the output speed of the power source.

[0074] When the rotating basket rises to the high position, the gear set descends under the action of gravity and disengages from the rotating basket and / or the power source, so that the rotating basket is no longer driven by the gear set.

[0075] In this embodiment, the structure that keeps the gear set in meshing transmission is a protrusion 23 on the bottom of the mop bucket. The protrusion can hold the gear set in place and keep it in the upper position, thereby achieving meshing transmission.

[0076] The single-bucket lifting cleaning tool of the present invention achieves two functions: washing the mop in water and wringing it out of the water by lifting the rotating basket. When washing in water, the resistance of the water makes the washing process relatively strenuous. The present invention achieves a strenuous effect by reducing the speed through the gear set. That is, the rotating basket moves slowly during washing but requires less effort, and it moves quickly during wringing. At the same time, since there is no water resistance, it is also less strenuous. In addition, the lower rotation speed can also prevent water from splashing out due to excessive speed.

[0077] The power source includes existing solutions such as electric, foot-operated, or hand-operated mop handles. In this embodiment, the mop is a downward-rotating mop.

[0078] It also includes a drive column 30, which can be connected to the mop and driven to rotate by the mop, and the drive column constitutes the power source;

[0079] The drive column is rotatably connected to the rotating basket, and the drive column is coaxial with the rotating basket, that is, the drive column is located at the center of the rotating basket.

[0080] like Figures 1 to 4 As shown: The lifting mechanism includes a lifting frame 101 connected to the mop bucket 2. The lifting frame can be raised and lowered along a preset path and has a high position and a low position. The preset path is set on the mop bucket and / or the lifting frame.

[0081] It also includes a support mechanism for stopping the lifting frame at the high position, such as... Figure 4 As shown and Figure 5 As shown: The support mechanism includes a support column 102 and a support block 103 with a maze slide 1031;

[0082] The maze slide has an entrance 10311 for the support column to slide into and a support portion 10312 that can hold the support column and position it at the high position.

[0083] The support block is slidably connected to the lifting frame or the mop bucket. When the support column slides into the maze slide, the support block can move to accommodate the sliding of the support column in the maze slide.

[0084] It also includes a rotating basket 3, which is rotatably connected to the lifting frame.

[0085] When in use, the mop is placed in the rotating basket and rotates. When the rotating basket is in the low position, water can be stored in the mop bucket, and the rotating mop can be washed. When the rotating basket is in the high position, the mop leaves the water in the mop bucket and rotates to wring out the water.

[0086] The maze slide described in this invention refers to a slide that slides within an irregular track using cooperating positioning columns. By changing the position, it achieves cyclic positioning or disengagement, as detailed in the applicant's prior application (patent application CN111248824A). The maze slide of this invention is similar in principle. However, this invention creatively sets the maze slide as a movable structure to adapt to the positional changes of the support columns within the track. This allows the lifting frame to move only vertically during lifting and lowering, without requiring movement in left or right directions, thus facilitating lifting and lowering operations.

[0087] More specifically, in this embodiment, the support block is slidably connected to the lifting frame, and the support column is fixedly connected to the inner wall of the mop bucket or is an integral structure with the mop bucket.

[0088] The lifting frame has a connecting part 1011 that connects to the mop bucket. The connecting part includes a hollow cavity 10111. The support block is placed in the cavity and can move linearly to accommodate the sliding of the support column in the maze slide.

[0089] In other words, this embodiment achieves linear movement by directly installing the support block inside the tubular structure, thus restricting the direction of movement of the support block. The structure is simple, has a long lifespan, and is low in cost.

[0090] In addition, such as Figure 4 and 5 As shown, the connecting part also has an opening on the side facing the support column, which allows the support column to enter the maze slide.

[0091] like Figures 5 to 7 As shown: The dehydration device of the present invention is further provided with a limiting structure 21, which is used to limit the position of the support block during the lifting process of the lifting frame.

[0092] That is, by restricting the position of the support block, it is ensured that when the lifting frame reaches the high position, the support column can enter from the entrance of the maze slide.

[0093] The limiting structure can use an elastic element to realize the movement and reset of the support block, or it can use a fixed structure to achieve this through interference blocking.

[0094] Specifically, the direction of movement of the support block is defined as direction A, and the cavity has through openings 10112 on opposite sides of direction A. When the support block slides within the cavity, its two sides can extend out from the openings.

[0095] The limiting structure is a blocking part provided on one or both sides of the support block. The blocking part can interfere with the protruding support block to limit the position of the support block.

[0096] When set on one side, it can be used in conjunction with an elastic element.

[0097] This embodiment adopts a structure with barriers on both sides, which can solve the problems of short lifespan and easy failure of elastic components.

[0098] The limiting structure includes a protrusion 211 on the inner wall of the mop bucket. The protrusions are arranged in pairs and are located on both sides of the support block.

[0099] It is understandable that, since the support block is capable of rising and falling, the two sides here are actually set according to the preset path of the lifting frame.

[0100] By placing the support block between the two protruding strips, the sliding of the support block can be restricted, thereby keeping the support block in the same position during the rising or falling process. This allows the support column to be aligned with the entrance of the maze slide, enabling it to smoothly enter the maze slide.

[0101] Meanwhile, when the lifting frame rises to the high position, that is, when the support column enters the maze slide, the support block needs to move. At this time, the protrusion needs to be set to make way for the movement of the support block. In this embodiment, the height of the protrusion is less than the height of the lifting frame when it is in the high position; that is, the height of the protrusion is shortened to make way.

[0102] In addition, in this embodiment, to facilitate the smooth entry of the support block between the two protruding strips when the lifting frame descends from the high position,

[0103] The portion of the support block extending out of the opening has a sloping lower edge.

[0104] In this embodiment, as Figure 5 As shown: the preset path is a vertically arranged track 104, and the lifting frame can rise or fall vertically along the track.

[0105] The track includes a vertically arranged protrusion located on the inner wall of the mop bucket, and the lifting frame has a slot 1012 that can engage with the protrusion and slide along it.

[0106] By using a simple concave-convex structure to restrict the degree of freedom, it is possible to set up linear motion only. Although the fitting precision of this structure is not high, it has a long service life and high reliability.

[0107] The lifting frame includes at least two legs 1013 connected to the mop bucket, and the support mechanism is located at one end of the legs close to the mop bucket.

[0108] In this embodiment, the mop bucket has a circular structure, and the support legs are provided with three, which provides good stability.

[0109] It is understandable that the number of legs can be arbitrarily set according to the structure of the barrel and the requirements.

[0110] The specific structure of the power source is as follows: Figure 1 , Figure 2 , Figure 8 and Figure 9 As shown: The mop head 11 of the mop has a drive hole 111 that connects with the drive column. The drive hole and the drive column are a matching polygonal structure, that is, the circumferential anti-rotation function is achieved through the polygonal structure, and the drive column is directly driven to rotate by the mop handle.

[0111] The mop head includes an inner disc 112 and an outer disc 113. The inner disc is connected to the mop handle and can be driven to rotate by the mop handle. The outer disc is coaxially arranged with the inner disc and rotatably connected to the inner disc. The drive hole is located in the inner disc. The mop's wiping material is installed on the outer disc.

[0112] It also includes a linkage pin 12, which is located at the connection between the inner disk and the outer disk, and the linkage pin can move to lock the inner disk and the outer disk so that they rotate synchronously, or move to disengage from the lock so that the inner disk and the outer disk can rotate separately.

[0113] One end of the linkage pin extends out of the inner wall of the drive hole and can reciprocate in the direction of extension;

[0114] More specifically: one side of the linkage pin has a protrusion 121, which can slide into or out of the notch 1131 of the outer disk, and is also provided with an elastic element for driving the linkage pin to reset.

[0115] When the linkage pin is in normal operation, the inner and outer disks are locked and rotate synchronously; when the extended part is retracted or partially retracted by the push of the drive pin, the inner and outer disks separate and rotate independently.

[0116] like Figure 1 and Figure 10As shown: The contact position between the outer disk and the rotating basket is also provided with first teeth 113A and 113B that enable the two to engage and rotate synchronously.

[0117] like Figure 4 and Figure 5 As shown: The drive column is rotatably connected to the rotating shaft 22 fixed inside the mop bucket. The drive column can rotate around the rotating shaft and can slide back and forth along the axial direction of the rotating shaft.

[0118] like Figure 13 and Figure 14 As shown: The drive column and the rotating basket are provided with second teeth 30A and 30B that can engage, and the reciprocating sliding constitutes engagement or disengagement. When engaged, the drive column and the rotating basket stop rotating relative to each other. When disengaged, the drive column and the rotating basket separate and rotate.

[0119] When the rotating basket is in the low position, one end of the rotating shaft extends out of the end of the drive column. At this time, the mop is supported by the rotating shaft, and the second tooth disengages.

[0120] When the rotating basket is in the high position, one end of the rotating shaft retracts into the end of the drive column. At this time, the mop is supported by the drive column, and as the mop is pressed down, the drive column is driven to move down so that the second tooth engages and achieves linkage.

[0121] The gear set is a planetary gear mechanism, such as... Figure 11 and Figure 12 As shown: It includes a sun gear 201, planet gears 202, an internal gear carrier 203, and a planet carrier 204;

[0122] The planetary gear mechanism, the drive column, and the rotating basket are coaxially arranged.

[0123] The sun gear and the drive column have first ratchet teeth 201A and 201B that can mesh, and the planet carrier and the rotating basket have second ratchet teeth 204A and 204B that can mesh. The first ratchet teeth and the second ratchet teeth are located on the same side of the planetary gear mechanism.

[0124] The sliding of the gear set can form the connection or disengagement with the power source and the rotating basket as described above, and in this embodiment, the two ratchet teeth are connected or disengaged simultaneously.

[0125] The gear set is installed in the cavity 1014 of the lifting frame, and the gear set is slidably connected to the cavity; the inner sidewall of the cavity and the gear set have a concave-convex structure (including matching protrusions 1015 and grooves 1016) to prevent relative rotation between the two.

[0126] The complete washing and dehydration process is as follows:

[0127] When the lifting frame is in the low position, the gear set remains in the upper position under the support of the boss. That is, the first and second ratchet teeth between the gear set, the drive column, and the rotating basket are engaged. In addition, when in the low position, the rotating shaft protrudes from the end of the drive column. At this time, when the mop is pressed down to apply power, the drive column is not under force. Therefore, the second tooth between the drive column and the rotating basket is not engaged, and the two are separated and rotate independently. At the same time, the inner and outer discs on the mop also rotate separately when the linkage pin is retracted.

[0128] The transmission process at this time is as follows: the mop handle drives the inner disc to rotate (this is the speed of the power source, defined as the first speed, which is relatively fast), the inner disc drives the drive column to rotate, the drive column drives the input of the gear set (sun gear), the output of the gear set (planet carrier) drives the basket to rotate (this is the second speed after the gear set is changed, which is relatively slow), the basket drives the outer disc to rotate. Here, the rotation of the outer disc is accomplished by the first tooth. The two maintain a synchronized speed, which is better for the cleaning effect. That is to say, cleaning can still be performed even if this first tooth is not set.

[0129] When the lifting frame is in a high position, the gear set descends under the action of gravity. At this time, the first and second ratchet teeth disengage, meaning the gear set does not engage. Simultaneously, in the high position, the mop provides power by pressing down directly onto the drive column. Therefore, under this downward pressure, the second teeth between the drive column and the rotating basket actually engage. At this time, the speed of the rotating basket is the same as the first speed of the inner disc. The first speed of the rotating basket is also transmitted to the outer disc of the mop. That is, the inner disc, outer disc, and rotating basket of the mop are all provided by the first speed of the mop handle. This speed is relatively fast, which is beneficial for rotation and dehydration.

[0130] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
