Description

Clean-in-place and spin-dry flat mop cleaning tool

technical field

The invention relates to a cleaning tool, in particular to a flat mop cleaning tool that can be cleaned and dried in place.

Background technique

The rotary mop has the advantages of convenient cleaning and dehydration, especially the cleaning effect of the semi-dry and wet mop can be achieved. At present, it has been used more and more widely in life, including the mop bucket and the mop bar. The mop head of the wiper, the mop rod includes an inner rod and an outer rod that are sleeved with each other, a drive structure that can convert the telescopic motion of the outer rod into the rotary motion of the inner rod is arranged between the inner and outer rods, and the mop bucket is provided with A rotatable wash pan and dewatering basket, the wash pan is below the water surface and the dewatering basket is above the water surface. During washing, the rotation of the mop head is beneficial to drive the washing plate in the mop bucket to rotate, realizing the stirring and washing of the mop head in water; during dehydration, the rotation of the mop head is beneficial to drive the dehydration basket in the mop bucket to rotate, realizing the function of centrifugal dehydration.

For example, the mop disclosed in the Chinese utility model patent "Hand-Pressed Rotary Mop" published with the announcement number CN201755206U, and the dehydration bucket disclosed in the Chinese utility model patent "Hand-Pressed Rotary Mop Dedicated Dehydration Bucket" with the announcement number of CN201775610U, can realize Washing and drying of hand-pressed rotary mops. This kind of mop bucket is mainly suitable for hand-pressed round cotton yarn mops, but in use, the hand-pressed round cotton yarn mop is not as convenient as a flat mop (a mop with a flat mop head), especially when cleaning corners or along walls The round cotton gauze mop is more inconvenient when the side is removed.

There are also a small number of mop buckets on the market for cleaning and dehydrating flat mops, but this kind of mop bucket requires that the flat mop needs to be folded during dehydration, and the folded flat mop head has a certain height. For drying, the dehydration basket needs to be made higher to accommodate the folded flat mop head. At the same time, the height of the bucket body also needs to be increased accordingly. While accommodating the dehydration basket, the bucket body also needs to leave a certain space under the dehydration basket to accommodate Water thrown down. Moreover, the mop bucket suitable for flat mop can be cleaned and de-dryed in two parts in one bucket and carried out independently.

Another relatively reasonable cleaning bucket, such as the structure disclosed in the Chinese invention patent application "Mop Lifting Self-Cleaning Device" with publication number CN108618716A, includes a mop and a cleaning bucket, and the mop includes a mop head, a rotatable mop rod, and a mop cloth. , the mop cloth is arranged on the mop head, and the mop head includes a base, a shell, and a swing piece. The swing piece is rotatably connected to the base, and the swing piece can be unfolded to drive the shell. Active connection; a roller and a support body are arranged in the cleaning bucket, and the roller is set to rotate with its own axis as the rotation axis; during cleaning, when the mop head rotates at a slow speed, the mop drives the roller to rotate; the mop head rotates rapidly When the oscillating piece moves up the casing due to centrifugal action, the mop is separated from the roller. The self-cleaning device must use a mop lifting structure to complete the cleaning and drying of the mop, which directly leads to a more complex structure of the cleaning bucket, and the lifting structure has high requirements for the coordination of various components, which is prone to failure; the water level must be high (close to The wipes at the bottom of the mop head), which is a waste of water; the dirty water after cleaning enters the cleaning bucket and mixes with the original clean water, which affects the cleaning effect.

SUMMARY OF THE INVENTION

The technical problem to be solved by the present invention is to provide a flat mop cleaning tool for in-situ cleaning and drying with simple and reasonable structure and low failure rate, and the mop bucket is more economical while cleaning the flat mop efficiently. Use water.

The technical solution adopted by the present invention to solve the above technical problems is as follows: a flat mop cleaning tool for in-situ cleaning and drying, comprising a mop and a cleaning bucket, and the mop comprises a flat mop connected to the lower end of a hand-pressed rotating mop rod The bottom surface of the flat mop head is provided with wipers, and the cleaning bucket is provided with a support member that supports the bottom of the flat mop head; it is characterized in that: the cleaning bucket is also provided with a water container for holding clean water, The water box is located below the flat mop head resting on the support. The water box is provided with a rotatable cleaning part. The rotation of the flat mop head can directly or indirectly drive the cleaning part to rotate; the water level in the water box is at a high level. When the cleaning part rotates, it can bring the clean water in the water box to the wiper that rotates with the flat mop head, so as to realize cleaning; when the water level in the water box is at a low level, the rotation of the cleaning part will no longer bring the water to the follower. The flat mop head rotates with the wipes for spin drying.

Alternatively, the cleaning member is a roller or a roller with bristles on the surface or a vane wheel. The roller with bristles on the surface can wipe the wipes during the rotation process, and the blade wheel has a more water-rejecting effect.

Preferably, the rotation of the flat mop head can drive the cleaning member to rotate through the direct frictional contact between the wiper and the cleaning member. In this structure, the flat mop head directly drives the cleaning component to rotate through friction, and no additional driving structure is required. The entire cleaning bucket has a simpler structure and lower cost.

In order to ensure that the cleaning components are in full contact with the flat mop head, preferably, the cleaning components are floating in the water box and can move up and down relative to the water box, and are also provided with elastic members that keep the cleaning components moving upward. Because the elastic part keeps the cleaning part moving upward as a whole, it is better in contact with the wiper, and the rotation of the flat mop head can fully drive the cleaning part to rotate along with it. The specific cleaning component is supported in the water box by a rotating shaft, the rotating shaft can move up and down relative to the water box, and an elastic member is arranged below the rotating shaft to keep the rotating shaft moving upward.

In order to realize the automatic water storage of the water storage box, the middle part of the above-mentioned water storage box is rotatably supported in the cleaning bucket through the rotating shaft, the cleaning part is located on one side of the rotation axis, and the water storage box has the rotation axis as the axis on the other side of the rotation axis. The tendency to turn sideways downward; in the state where the flat mop head rests on the support, the flat mop head presses down the cleaning part to force the water container to turn over and keep it in a horizontal position. When the flat mop head is not placed on the support, the side of the water box is turned down and submerged below the water level of the cleaning bucket. When the flat mop head is placed on the support, the flat mop head is pressed down to clean The components force the water container to be turned over to keep it in a horizontal position, and the water container will hold the water in the cleaning bucket. Although the dirty water after cleaning will enter the cleaning bucket, but after the next use, the dirt will sink to the bottom after the water in the cleaning bucket sits for a period of time, and the water in the water box will still be relatively clean next time.

There are many ways to realize the turning tendency of the water box, which can be specifically adopted but not limited to the following methods. The water box keeps the counterweights of the flip trend.

In order to achieve complete separation of clean water and sewage, the cleaning bucket is also provided with an external water supply chamber, the water outlet of the external water supply chamber is aligned with the water box, and a control valve is provided on the water outlet of the external water supply chamber. The water supply room only supplies clean water to the water box, and the dirty water that has been cleaned with the wipes flows into the cleaning bucket. The cleaning effect is good. It is better that the inner bottom of the water supply room is higher than the water box. For clean water, the water supply chamber can be integrally formed with the cleaning bucket, which is convenient for manufacturing. Of course, the water supply chamber can also be a container that is externally hung on the cleaning bucket and is provided independently from the cleaning bucket. The external water supply chamber is preferably arranged around the outer peripheral wall of the cleaning tub. This layout not only increases the volume of the water supply chamber, but also stabilizes the center of gravity of the entire cleaning bucket, making it difficult to tip over.

In order to better clean the wipes, the cleaning bucket or the water container is also provided with a scraping member, which is used for scraping the bottom surface of the wipe that rotates with the flat mop head.

Further improvement, the above-mentioned water holding box is provided with a water inlet hole, and an opening and closing water injection valve is arranged in the water inlet hole; the water injection valve is opened, and the water in the cleaning bucket enters the water holding box through the water inlet hole; when cleaning and drying, water injection The valve is closed, and the water in the cleaning bucket cannot enter the water tank through the water inlet hole.

As a further improvement, the above water injection valve is a normally open valve, and the water injection valve is triggered and closed by the flat mop head resting on the support. The structure can fully realize the automatic water supply to the water storage box without manual override of the valve or water injection into the water storage box. When using, pour water into the cleaning bucket. The water level of the water filling is higher than the bottom surface of the water box but lower than the top surface of the water box. The cleaning bucket is not working, the water injection valve is opened, and the water automatically enters the water box (connector principle) ; When cleaning and drying, the flat mop head rests on the support, the water filling valve is triggered and closed by the flat mop head, and the water in the cleaning bucket cannot enter the water box through the water inlet hole; when the water level in the water box is at a high level , the rotation of the cleaning part can bring the clean water in the water box to the wiper that rotates with the mop head of the flatbed, so as to realize cleaning; when the water level in the water box is at a low level, the rotation of the cleaning part will no longer bring the water to the flatbed. The mop head rotates with the wipes to achieve spin-drying. Although the dirty water after cleaning will enter the cleaning bucket, but after the next use, the dirt will sink to the bottom after the water in the cleaning bucket sits for a period of time, and the water in the water box will still be relatively clean next time.

Compared with the prior art, the advantages of the present invention are:

1. When the water level in the water box is at a high level, the rotation of the cleaning component can bring the clean water in the water box to the wiper that rotates with the flat mop head, so as to realize cleaning; during the rotation of the flat mop head, the water box The inner water level gradually decreases, and when the water level in the water box is at a low level, the rotation of the cleaning component will no longer bring water to the wiper that rotates with the flat mop head, thereby achieving drying. The clean water in the water box is always used to clean the wipes, and the cleaning effect is good.

2. Because the cleaning and drying operations are completed at the same height, there is no need to set the cleaning position and the drying position in the cleaning bucket respectively, and there is no need to design the flat mop head as a lifting structure. The overall structure is simpler and the volume is smaller. Therefore, The manufacturing cost is low, and the failure rate is low and the user experience is better. When operating, you only need to press the mop bar up and down, and there is no need to change the position.

3. When the cleaning tool is rotated for cleaning, the wipes basically cover the water surface in the cleaning bucket, so the water will not splash out of the bucket during rotating cleaning.

Detailed ways

The present invention will be further described in detail below with reference to the embodiments of the accompanying drawings.

As shown in Figures 1-3, it is the first embodiment of the water-saving mop bucket of the present invention.

A flat mop cleaning tool for in-situ cleaning and drying, comprising a mop 1 and a cleaning bucket 2, the inner cavity of the cleaning bucket 2 is circular, and the mop 1 comprises a flat plate connected to the lower end of a hand-pressed rotating mop rod 11 The mop head 12, the bottom surface of the flat mop head 12 is provided with a wiper 3, the wiper 3 can be a rag or the like, and the wiper 3 is annular, so that the bottom surface of the flat mop head 12 is exposed, and the rotary mop is pressed by hand. The rod 11 is of the prior art.

The cleaning bucket 2 is provided with a support member 4 that supports the bottom of the flat mop head 12; specifically, the cleaning bucket 2 has an arched boss portion 21 in the middle, and a support shaft is inserted in the middle of the boss portion 21. The hemispherical surface is used for the center position of the bottom surface of the top-column flat mop head 12 , and the support shaft constitutes the support member 4 .

The cleaning bucket 2 is fixed with a water storage box 5 for holding clean water. The water storage box 5 in this embodiment is fan-shaped, and its area is roughly about a quarter of the area of the inner cavity of the cleaning bucket 2. Below the flat mop head 12 resting on the support 4, the water box 5 is located in the middle of the cleaning bucket 2 in the height direction, preferably below half the height of the cleaning bucket 2, so that it is not easy to remove water when drying. Throw out the cleaning bucket 2 and try to get as close to the bottom of the cleaning bucket 2 as possible, so that the overall height of the cleaning bucket 2 can be reduced.

There is a rotatable cleaning part 6 in the water box 5, the cleaning part 6 is close to the outermost side of the water box 5, and the rotation direction of the flat mop head 12 is from the side of the water box 5 provided with the cleaning part 6 to the outermost part of the water box 5. The direction of rotation of the water box 5 is optimal, so as to ensure that the dirty water that is wiped off does not flow to the water box 5 to the greatest extent possible, and also facilitates the cleaning of the parts 6 to clean the wipes 3 just wet by the water.

The rotation of the flat mop head 12 in this embodiment can directly drive the cleaning member 6 to rotate; that is, the rotation of the flat mop head 12 can drive the cleaning member 6 to rotate through the direct frictional contact between the wiper 3 and the cleaning member 6 .

When the water level in the water box 5 is at a high level (the water level is at least higher than the bottom of the cleaning part 6, generally higher than half of the height of the cleaning part 6), the rotation of the cleaning part 6 can bring the clean water in the water box 5 to the follower plate The mop head 12 rotates on the wiper 3 together to realize cleaning, because the cleaning part 6 squeezes the wiper 3; when the water level in the water box 5 is at a low level (the water level is lower than the bottom of the cleaning part 6 or there is basically no water) ), at this time, the rotation of the cleaning member 6 no longer brings water to the wiper 3 that rotates with the flat mop head 12, thereby achieving spin drying.

The cleaning part 6 is a roller or a roller or a blade wheel with bristles on the surface. A roller with bristles on the surface is best. The cleaning member 6 is floated in the water storage box 5 and can move up and down relative to the water storage box 5 , and is also provided with an elastic member 7 that keeps the cleaning member 6 moving upward. Specifically, the cleaning member 6 is supported in the water box 5 through the rotating shaft 61, and two shaft seats 62 are provided in the water box 5 to support the left and right ends of the rotating shaft 61, and the shaft seats 62 are constrained to the water box. 5 and can only move up and down, and the lower part of the shaft seat 62 is provided with an elastic member 63 (preferably a spring) that keeps the rotating shaft 61 moving upward.

The cleaning bucket 2 or the water storage box 5 is also provided with a scraping member, and the scraping member is used to scrape the bottom surface of the wiper 3 that rotates with the flat mop head 12 . The wiper element is not shown in the drawings, it could be a bristles or a wiper strip.

The working principle and process of this cleaning tool are as follows:

Cleaning process: first fill the water box 5 with water to a certain height (reach the high water level), then pour clean water directly into the water box 5, and then support the bottom of the flat mop head 12 on the support 4. At this time, The wiper 3 on the bottom surface of the flat mop head 12 presses the cleaning part 6, and the mop rod 11 is pressed up and down, the wiper 3 rotates rapidly together with the flat mop head 12, and the cleaning part 6 is driven by the frictional contact between the wiper 3 and the cleaning part 6. Rotation, the cleaning part 6 rotates to bring the clean water in the water box 5 to the wiper 3 , and the friction between the cleaning part 6 and the wiper can effectively clean the wiper 3 .

Spin-drying process: after the cleaning process is carried out for a period of time, the water in the water box 5 becomes less and less, and when the water level in the water box 5 drops to a low level, the rotation of the cleaning part 6 will no longer bring water to the mop head 12 with the flatbed. The wipes 3 are rotated together, and the rapid rotation of the flat mop head 12 at this time can achieve centrifugal dehydration.

The clean water in the water box 5 is always used to clean the wiper 3, and the cleaning effect is good. Since both cleaning and drying are completed at the same height, there is no need to separately set the cleaning position and the drying position in the cleaning bucket 2, and there is no need to design the flat mop head 12 as a lifting structure. The overall structure is simpler and the volume is smaller. Therefore, the manufacturing The cost is low, and the failure rate is low and the user experience is better. When operating, it is only necessary to press the mop bar 11 up and down, and there is no need for transposition operation. When the cleaning tool is rotated for cleaning, the wiper 3 basically covers the water surface in the cleaning bucket 2, so the water liquid will not splash out of the bucket body during the rotational cleaning.
