Description

A flat mop device with visible water volume Technical Field

[0001] This utility model relates to the field of mops, specifically to a flat mop device with visible water volume. Background Technology

[0002] Flat mops are a common floor cleaning tool in daily life. They are usually used with a mop bucket. After cleaning the floor, the flat mop is placed in the mop bucket for cleaning and wringing. Existing mop buckets include separate wringing and rinsing areas. The rinsing and wringing of the flat mop need to be done in two different areas, and the same water is always used to clean the flat mop. After one or more cleanings, the water will become dirty, reducing the cleaning efficiency of the flat mop.

[0003] To address the aforementioned issues, Chinese patent CN217610946U discloses a "Mop Cleaning Device with Cleaning and Drainage Mechanism." This patent's mop bucket, by incorporating a water storage chamber and a water supply mechanism, ensures that the mop is always clean with water during each wash, thereby improving cleaning efficiency. However, the water level in the storage chamber cannot be directly observed; the water volume can only be assessed by removing the lid, making it somewhat inconvenient to use. Utility Model Content

[0004] One objective of this invention is to provide a flat mop device with visible water volume to solve the aforementioned problems.

[0005] To achieve the above-mentioned objectives, this utility model is implemented through the following technical solutions:

[0006] A flat mop device with visible water level includes a flat mop and a mop bucket. The mop bucket includes an upper bucket and a lower bucket that are detachably connected. One side of the upper bucket forms a cleaning zone, and the other side has a clean water zone separated from the cleaning zone. The flat mop enters the cleaning zone downwards. Water from the clean water zone is sprayed into the cleaning zone by a pumping device for the flat mop to clean itself. Wastewater generated in the cleaning zone flows downwards into the lower bucket. The lower bucket has a frame below the cleaning zone to prevent water from the lower bucket from entering the cleaning zone. The upper bucket is made of a transparent material so that the remaining water level in the clean water zone can be observed from the side wall of the upper bucket. Existing mop buckets typically have a separate area inside the bucket to form a clean water zone, while the area outside forms a washing zone and a wastewater zone. With this partitioned design, making the clean water zone transparent is difficult and costly to produce via injection molding. If the entire mop bucket is made transparent, the wastewater zone is also visible from the outside, and the dirt in the wastewater zone affects the aesthetics. The mop bucket of this invention changes the distribution of the clean water zone and other zones, making the clean water zone transparent so the amount of clean water is visible, while the wastewater zone is made of an opaque material, preventing dirt from showing and affecting the aesthetics. Furthermore, the upper and lower buckets are detachably connected, eliminating the need to move the entire mop bucket when adding or draining water. The upper bucket can be moved separately to add clean water, and the lower bucket can be moved separately to empty wastewater, making adding and draining water much easier.

[0007] Preferably, the upper bucket is equipped with a first bucket lid, which has a cleaning port and a water inlet at positions corresponding to the cleaning zone and the clean water zone, respectively. A squeezing device is located at the cleaning port away from the clean water zone and the water inlet. The flat mop enters the cleaning zone and cooperates with the squeezing device to clean or wring out the water. During cleaning, the wiping material is kept away from the clean water zone to prevent wastewater from entering and affecting water quality.

[0008] Preferably, the frame divides the lower bucket into a first wastewater zone and a second wastewater zone, and a water passage is provided between the frame and the lower bucket. Wastewater generated in the cleaning area flows downward into the first wastewater zone, and wastewater from the first wastewater zone flows into the second wastewater zone through the water passage, thereby achieving liquid level balance between the first and second wastewater zones. To reduce the volume of the mop bucket and thus the packaging and storage volume, the width of the mop bucket is slightly larger than the width of the flat mop, the size of the frame is adapted to the flat mop, and the volume of the first wastewater zone is smaller than the volume of the second wastewater zone. A water passage is provided on the side or bottom of the frame to discharge wastewater from the first wastewater zone into the second wastewater zone, thereby increasing the overall capacity of the wastewater zone.

[0009] Preferably, the lower bucket has a support ring on the inner side of its opening, and the support ring has a first step and a second step. The bottom of the upper bucket has a third step and a fourth step, and the third step and the fourth step are respectively supported on the first step and the second step. This facilitates the upper bucket being stably supported on the lower bucket.

[0010] Preferably, the support ring extends inward to form a second bucket lid, which has a water inlet below the squeezing device. The frame is fixed to the second bucket lid and can be removed from the lower bucket along with the support ring / second bucket lid. The second bucket lid can cover the opening of the lower bucket, preventing sewage from contacting the bottom of the clean water area, and can also reduce sewage spillage when moving and pouring water.

[0011] Preferably, the second bucket lid is also provided with an installation port, in which a buoy is installed. The buoy moves up and down with the water level in the lower bucket. When the water level in the lower bucket reaches a preset storage capacity, the buoy extends out of the installation port, and its position can be observed through the side and bottom walls of the upper bucket. The buoy changes position using the buoyancy provided by the water when in contact with it, either being exposed in the installation port or changing position within it. The position of the buoy is observed through the transparent side and bottom walls of the upper bucket to determine the water level in the lower bucket, allowing for timely emptying of water based on the buoy's position.

[0012] Preferably, a disassembly switch is provided between the upper bucket and the lower bucket or the support ring. The upper end of the disassembly switch is rotatably connected to the lower end of the upper bucket, and the lower end of the disassembly switch is fastened to the lower bucket or the support ring, so as to realize the fixing and disassembly separation of the upper bucket and the lower bucket.

[0013] Preferably, the lower end of the upper bucket is provided with a support column, which abuts against the support ring or the second bucket lid. When the upper bucket and the lower bucket are disassembled, the support column stably supports the upper bucket on the ground. Since the support area between the support ring and the upper bucket is limited, and the disassembly switch extends from the bottom of the upper bucket, the support column increases the mating area. This allows the upper bucket, which has a certain weight after adding purified water, to be stably supported on the lower bucket through the middle and outer periphery. Furthermore, after the upper bucket is disassembled, there is no need to change the position of the disassembly switch, as it can be supported on the ground by the support column.

[0014] Preferably, the water pumping device includes a water pump, a water pumping gear, a water pumping wheel, and a spray head. The water pumping gear is located between the cleaning area and the clean water area. The water pumping wheel is movably connected to a water pumping linkage at an eccentric position. The other end of the water pumping linkage is movably connected to the water pump core of the water pump. The mop head of the flat mop has a first rack along its length. When the mop head passes through the cleaning port, the first rack can mesh with the water pumping gear. The up and down movement of the mop head can drive the water pump to pump water through the water pumping gear, the water pumping wheel, and the water pumping linkage. The spray head is located in a different direction from the water pumping gear at the cleaning port. The spray head is connected to the water pump through a water pumping channel. The spray head has a spray nozzle that can spray the water pumped by the water pump onto the wiping object.

[0015] Preferably, the bottom of the water purification area is provided with a recessed platform, and the water pump is located in the recessed platform. The lower end of the recessed platform is flush with the lower end of the support column, so as to jointly support the upper tank on the second tank lid or the ground. The recessed platform is set so that the water pump is located at the lowest position of the water purification area, and most of the water in the water purification area can be pumped out for cleaning. The recessed platform also provides the same support function as the support column.

[0016] The advantages of this invention are as follows: Existing mop buckets generally have a separate area inside the bucket to form a clean water zone, while the area outside the clean water zone forms a washing zone and a wastewater zone. Under this partitioning, making the clean water zone of the mop bucket transparent is difficult and costly to produce via injection molding. If the entire mop bucket is made transparent, the wastewater zone can also be observed from the outside, and the dirt in the wastewater zone affects the aesthetics. The mop bucket of this invention changes the distribution of the clean water zone and other zones, making the clean water zone transparent so that the amount of clean water is visible, while the wastewater zone is made of opaque material, so that dirt will not affect the aesthetics. Furthermore, the upper and lower buckets are detachably connected, so there is no need to move the entire mop bucket when adding water or draining water. The upper bucket can be moved separately to add clean water, and the lower bucket can be moved separately to empty wastewater, making adding water and draining water much easier.

[0017] To reduce the volume of the mop bucket and thus the packaging and storage volume, the width of the mop bucket is slightly larger than the width of the flat mop. The size of the frame is adapted to the flat mop, and the volume of the first wastewater area is smaller than that of the second wastewater area. A water passage is provided on the side or bottom of the frame to discharge wastewater from the first wastewater area into the second wastewater area, thereby increasing the overall capacity of the wastewater area.

[0025] The embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so that the implementation of this utility model can be fully understood and carried out based on how technical means are used to solve technical problems and achieve technical effects.

[0026] This utility model uses certain terms to refer to specific components. Those skilled in the art will understand that this specification and claims do not distinguish components by differences in name, but rather by differences in function. It should be noted that, unless otherwise specified, when a component is described as "provided with," "located on," or "located on" another component, it can mean directly provided with or located on another component, or it may also mean there is a component in between; it can be an integral structure or a separate structure. When a component is described as "connected" to another component, it can mean a direct connection or a connection through a component in between; it can be an integral connection, a separate connection, or a contact fit. When a component is described as "located on another component," it does not necessarily mean that the component is located above or on top of the other component; it can be in other positions. The terms "upper," "lower," "left," "right," "high," "lower," and similar expressions used herein are based on the normal placement state of the product and are merely for illustrative purposes. The term "multiple" used herein refers to two or more items. The terms "vertical" and "horizontal" used in this article refer to a state that is roughly vertical or roughly horizontal within a reasonable margin of error, and do not necessarily have to be extremely precise.

[0027] As shown in Figures 1-7, a flat mop device with visible water volume includes a flat mop 1 and a mop bucket 2. The mop bucket 2 includes an upper bucket 3 and a lower bucket 4 that are detachably connected. One side of the upper bucket 3 forms a cleaning zone 5, and the other side is provided with a clean water zone 6 that is separated from the cleaning zone 5. The flat mop 1 enters the cleaning zone 5 downwards. The clean water zone 6 sprays water into the cleaning zone 5 through a water pumping device 7 for the flat mop 1 to use for cleaning. The wastewater generated in the cleaning zone 5 enters the lower bucket 4 downwards. The lower bucket 4 is provided with a frame 8 below the cleaning zone 5. The frame 8 prevents water in the lower bucket 4 from entering the cleaning zone 5. The upper bucket 3 is made of transparent material so that the remaining water volume in the clean water zone 6 can be observed from the side wall of the upper bucket 3.

[0028] Specifically, the upper tub 3 is integrally injection molded from transparent plastic, and a partition 9 is integrally molded between the washing zone 5 and the clean water zone 6. The washing zone 5 runs vertically through the area, while the clean water zone 6 is open at the top and enclosed in the other directions to form a water-filling cavity. The lower tub 4 is integrally molded from ordinary opaque plastic, with an open top to connect to and communicate with the upper tub 3. The washing and wringing of the flat mop 1 are both carried out in the washing zone 5. During washing, the water pumping device 7 sprays clean water from the clean water zone 6 onto the flat mop 1, and the wastewater generated from washing and wringing the flat mop 1 flows towards the cleaning zone 5. The water flows down into the lower bucket 4. The length of the flat mop 1 is slightly less than the height of the cleaning area 5, which is suitable for the entire object being wiped by the flat mop 1 to be cleaned and squeezed dry. In this embodiment, the clean water area 6 is located on one side of the upper bucket 3. The area of ​​the lower bucket 4, except for the frame 8, forms the sewage area. After the upper bucket 3 and the lower bucket 4 are connected, the frame 8 is located directly below the cleaning area 5 and is connected to the cleaning area 5. When the flat mop 1 enters the cleaning area 5 downwards, the lower end of the flat mop 1 is located in the frame 8. The setting of the frame 8 reduces the contact between the lower end of the flat mop 1 and the sewage in the lower bucket 4.

[0029] Existing mop buckets typically have a separate area inside the bucket for clean water, while the remaining area forms a washing zone and a wastewater zone. In this design, the clean water zone is made transparent (i.e., the clean water zone's sidewalls are made of transparent plastic), while the other areas are made of ordinary opaque plastic. This process involves separately injection molding the transparent and opaque parts of the bucket and then integrating them into one unit, which is difficult and costly. Conversely, if the entire mop bucket is made transparent, the wastewater zone is also visible from the outside. If the mop bucket isn't emptied regularly, dirt will adhere to the bucket and become difficult to clean, and this dirt is also visible from the outside. The dirty contents inside the bucket result in a poor user experience. In this utility model, the mop bucket 2 changes the positional distribution of areas such as the clean water zone 6, making the clean water zone 6 transparent so that the amount of clean water can be seen, while the dirty water zone is made of opaque material, so that the appearance is not affected by the dirt showing through. It can simultaneously ensure that the amount of clean water can be seen and that the dirt in the dirty water zone does not affect the appearance. The production process adds the step of separately injection molding the upper bucket 3 and the lower bucket 4, but does not increase the production difficulty. Moreover, the upper bucket 3 and the lower bucket 4 are detachably connected, so there is no need to move the entire mop bucket 2 when adding water and draining water. The upper bucket 3 can be moved separately to add clean water and the lower bucket 4 can be moved separately to empty the dirty water, making adding water and draining water more convenient.

[0030] Preferably, the upper bucket 3 is provided with a first bucket lid 10. The first bucket lid 10 is provided with a cleaning port 11 and a water inlet 12 at the corresponding positions of the cleaning area 5 and the clean water area 6, respectively. The cleaning port 11 is provided with a squeezing device 13 at a position away from the clean water area 6 and the water inlet 12. The flat mop 1 enters the cleaning area 5 and works with the squeezing device 13 to clean or wring out the water, as shown in Figure 5. The cleaning area 5 and the clean water area 6 are located on the left and right sides, respectively, separated by a partition 9. The squeezing device 13 is located on the left side of the cleaning area 5, away from the clean water area 6. When the flat mop 1 is cleaning and wringing out the water, the wiping material is on the left side, away from the direction of the clean water area 6. Even if some sewage splashes upward during cleaning and wringing, it will not enter the clean water area 6.

[0031] The squeezing device 13 in this embodiment includes a movable scraper 14 and a support wheel 15 opposite to the scraper 14. The support wheel 15 and the scraper 14 together clamp the flat mop 1, increasing the resistance between the wiping material and the scraper 14 to achieve cleaning and wringing. The scraper 14 is movable to adjust the resistance when the flat mop 1 moves upward away from the cleaning area 5, preventing the flat mop 1 from lifting the mop bucket 2 as a whole. The support wheel 15 is rotatably mounted on the first bucket cover 10, and can rotate to reduce the resistance of the flat mop 1 when it moves up and down.

[0032] As shown in Figures 3 and 5, the frame 8 divides the lower bucket 4 into a first sewage zone 16 and a second sewage zone 17. A water passage 18 is provided between the frame 8 and the lower bucket 4. Sewage generated in the washing area 5 flows downward into the first sewage zone 16, and sewage in the first sewage zone 16 flows into the second sewage zone 17 through the water passage 18, thereby achieving liquid level balance between the first sewage zone 16 and the second sewage zone 17. This invention aims to reduce the volume of the mop bucket 2, thereby reducing packaging and storage volume. The width of the mop bucket 2 is slightly larger than the width of the flat mop 1. The size of the frame 8 is adapted to the flat mop 1, and the volume of the first sewage zone 16 is smaller than that of the second sewage zone 17. A water passage 18 is provided on the side or bottom of the frame 8 to discharge sewage from the first sewage zone 16 into the second sewage zone 17, thereby increasing the overall capacity of the sewage zone.

[0033] As shown in Figure 5, in this embodiment, the frame 8 is detachably installed in the lower tank 4, dividing the lower tank 4 into a first sewage area 16 on the right and a second sewage area 17 on the left. In Figure 6, there is a gap between the upper and lower sides of the frame 8 and the side wall of the lower tank 4. This gap forms a water passage 18. The sewage generated in the washing area 5 flows downward to the first sewage area 16 located directly below the squeezing device 13. The water level in the first sewage area 16 is higher than that in the second sewage area 17. The sewage flows automatically through the water passage 18 to the second sewage area 17 to achieve the same level of liquid level in the two sewage areas.

[0034] As shown in Figures 2, 4, and 6, a support ring 19 is provided on the inner side of the opening of the lower bucket 4. The support ring 19 has a first step 20 and a second step 21. The bottom of the upper bucket 3 has a third step 22 and a fourth step 23, which are respectively supported on the first step 20 and the second step 21. If the upper bucket 3 is directly installed on the lower bucket 4, the lower bucket 4 needs to be flared outward to accommodate the insertion of the upper bucket 3, or an inward step can be set at the opening of the lower bucket 4. However, setting such a step increases the difficulty of production. The support ring 19 provides support between the upper and lower buckets 4, and the support ring 19 also increases the aesthetics of the mop bucket 2.

[0035] Preferably, as shown in Figures 3 and 4, the support ring 19 extends inward to form a second bucket cover 24. The second bucket cover 24 has a water inlet 25 below the squeezing device 13. The frame 8 is fixed to the second bucket cover 24 and can be removed from the lower bucket 4 along with the support ring 19 / second bucket cover 24. The second bucket cover 24 covers the sewage area, preventing the sewage from contacting the bottom surface of the upper bucket 3 when the sewage area is full, thus preventing the bottom surface of the upper bucket 3 from getting dirty. It also prevents the sewage from shaking and spilling when the lower bucket 4 is moved to pour water. The water inlet 25 is located directly below the squeezing device 13 to receive the sewage flowing downward from the cleaning area 5.

[0036] As shown in Figure 4, in this embodiment, the second bucket lid 24 is also provided with an installation port 26, and a float 27 is provided in the installation port 26. The float 27 moves up and down with the water level in the lower bucket 4. When the water level in the lower bucket 4 reaches the preset storage capacity, the float 27 extends out of the installation port 26, and the position information of the float 27 can be observed through the side wall and bottom wall of the upper bucket 3. If the water level in the sewage area is low and does not contact the float 27, the float 27 is located below the installation port 26, and the position of the float 27 cannot be observed through the side wall and bottom wall of the upper bucket 3. When the water level in the sewage area rises, the buoyancy provided by the sewage causes the float 27 to move upward and enter or extend out of the installation port 26, and the position information of the float 27 can be observed through the side wall and bottom wall of the upper bucket 3. The real-time water level in the sewage area can be judged by the position of the float 27 without disassembling the upper bucket 3 and the second bucket lid 24 to observe the water level, making it more convenient to use. Of course, the buoy 27 can also be positioned at the low position of the installation port 26 when the water level is low, and at the high position of the installation port 26 when the water level is high. The real-time water level can be determined by observing the height difference of the buoy 27.

[0037] Preferably, the buoy 27 is set to a conspicuous color such as red.

[0038] As shown in Figures 1, 2, and 6, a disassembly switch 28 is provided between the upper bucket 3 and the lower bucket 4 or support ring 19. The upper end of the disassembly switch 28 is rotatably connected to the lower end of the upper bucket 3, and the lower end of the disassembly switch 28 is fastened to the lower bucket 4 or support ring 19 to achieve the fixing and disassembly separation of the upper bucket 3 and the lower bucket 4. Alternatively, the disassembly switch 28 can be rotatably connected to the lower bucket 4 or support ring 19, and the disassembly switch 28 can be rotated upwards to fasten and fix to the lower end of the upper bucket 3.

[0039] Preferably, a disassembly switch 28 is provided on both opposite sides of the mop bucket 2 to achieve balanced fixation of both sides of the mop bucket 2.

[0040] As shown in Figures 3 and 6, the lower end of the upper bucket 3 is provided with a support column 29. The support column 29 abuts against the support ring 19 or the second bucket cover 24. When the upper bucket 3 and the lower bucket 4 are disassembled, the support column 29 will support the upper bucket 3 stably on the ground.

[0041] In the above embodiments, as shown in Figures 2, 3, and 7, the water pumping device 7 includes a water pump 30, a water pumping gear 31, a water pumping wheel 32, and a spray head 33. The water pumping gear 31 is disposed between the cleaning zone 5 and the clean water zone 6. The water pumping wheel 32 is movably connected to a water pumping connecting rod 34 at an eccentric position. The other end of the water pumping connecting rod 34 is movably connected to the water pump core of the water pump 30. The flat mop 1 has a first rack 35 along its length direction, and the mop head passes through the cleaning zone. When the cleaning port 11 is in operation, the first rack 35 can mesh with the water-pumping gear 31. The mop head can move up and down and drive the water pump 30 to pump water through the water-pumping gear 31, the water-pumping wheel 32 and the water-pumping connecting rod 34. The spray head 33 and the water-pumping gear 31 are located in different directions from the cleaning port 11. The spray head 33 is connected to the water pump 30 through the water-pumping water passage 36. The spray head 33 is provided with a spray nozzle 37, which can spray the water pumped by the water pump 30 onto the object being wiped.

[0042] Preferably, as shown in Figure 6, the bottom of the water purification area 6 is provided with a recessed platform 38, and the water pump 30 is located in the recessed platform 38. The lower end of the recessed platform 38 is flush with the lower end of the support column 29, so as to jointly support the upper bucket 3 on the second bucket cover 24 or the ground.

[0043] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
