Description

Technical Field

[0001] The utility model relates to the field of mops, in particular to a flat mop device with visible water volume. Background Art

[0002] The flat mop is a relatively common ground cleaning tool in life. It is generally used with a mop bucket. After cleaning the ground, the flat mop is placed in the mop bucket for cleaning and dehydration. The existing mop bucket includes an independent water squeezing area and a cleaning area. The cleaning and water squeezing of the flat mop need to be carried out in two different areas, and the same water is always used to clean the flat mop. After one or multiple cleanings, the water will become dirty, reducing the cleaning efficiency of the flat mop.

[0003] To solve the above problems, Chinese Patent CN217610946U discloses a "Mop Cleaning Device with Sewage Discharge and Drainage". The mop bucket of this patent is provided with a water storage cavity and a water supply mechanism, so that the mop is cleaned with clean water every time, in order to improve the cleaning efficiency of the mop. However, the water level in the water storage cavity cannot be directly observed, and only by removing the bucket cover can the water volume in the water storage cavity be observed, which is rather troublesome to use. Summary of the Utility Model

[0004] An object of the utility model is to provide a flat mop device with visible water volume to solve the above problems.

[0005] To achieve the above utility model object, the utility model is realized by the following technical solutions:

[0006] A flat mop device with visible water volume, comprising a flat mop and a mop bucket. The mop bucket includes a detachable upper bucket and a lower bucket. A cleaning area is formed through the upper and lower parts on one side of the upper bucket, and a clean water area separated from the cleaning area is provided on the other side. The flat mop enters the cleaning area downward. The clean water area sprays water to the cleaning area through a pumping device for the flat mop to clean. The sewage generated in the cleaning area enters the lower bucket downward. A surrounding frame is provided below the cleaning area in the lower bucket, and the surrounding frame blocks the water in the lower bucket from entering the cleaning area. The upper bucket is made of transparent material to observe the remaining water volume in the clean water area from the side wall of the upper bucket. In existing mop buckets, a separate area is generally set in the bucket body to form a clean water area, and the cleaning area and the sewage area are formed in the areas outside the clean water area of the bucket body. Under this partition setting, the position of the mop bucket corresponding to the clean water area is set to be transparent separately, which is difficult and costly in injection molding production. If the whole mop bucket is set to be transparent, the dirt in the sewage area can also be observed from the outside, which affects the appearance. In the mop bucket of the present utility model, the position distribution of areas such as the clean water area is changed, so that the clean water area is set to be transparent to make the clean water volume visible, and the sewage area is made of opaque material, and it will not affect the appearance due to the penetration of dirt; moreover, the upper bucket and the lower bucket are detachably connected, and there is no need to move the whole mop bucket when adding water and draining water. The upper bucket can be moved separately to add clean water and the lower bucket can be moved separately to pour sewage, making it more convenient to add water and drain water.

[0007] Preferably, the upper bucket is provided with a first bucket cover. The first bucket cover is provided with a cleaning port and a water injection port at positions corresponding to the cleaning area and the clean water area respectively. An extrusion device is provided at a position far from the clean water area and the water injection port of the cleaning port. The flat mop enters the cleaning area and cooperates with the extrusion device for cleaning or squeezing dry. When the flat mop is cleaned, the wiping object faces away from the clean water area to avoid sewage entering the clean water area and affecting the water quality.

[0008] Preferably, the surrounding frame divides the lower bucket into a first sewage area and a second sewage area, and a water passing channel is provided between the surrounding frame and the lower bucket. The sewage generated in the cleaning area enters the first sewage area downward, and the sewage in the first sewage area enters the second sewage area through the water passing channel to achieve the liquid level balance between the first sewage area and the second sewage area. To reduce the volume of the mop bucket and thus reduce 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 surrounding frame is adapted to the flat mop, and the volume of the first sewage area is smaller than that of the second sewage area. A water passing channel is provided on the side or bottom of the surrounding frame to discharge the sewage in the first sewage area to the second sewage area to increase the overall capacity of the sewage area.

[0009] Preferably, a support ring is provided inside the mouth of the lower barrel. The support ring is provided with a first step and a second step. The bottom of the upper barrel is provided with a third step and a fourth step. The third step and the fourth step are respectively supported on the first step and the second step, facilitating the stable support of the upper barrel on the lower barrel.

[0010] Preferably, the support ring extends inwards to form a second barrel cover. The second barrel cover is provided with a water inlet below the extrusion device. The surrounding frame is fixed on the second barrel cover, and the surrounding frame can be detached from the lower barrel along with the support ring / the second barrel cover. The second barrel cover can cover the mouth of the lower barrel, preventing sewage from contacting the bottom of the clean water area, and can also reduce the sloshing and spilling of sewage during the process of moving and pouring water.

[0011] Preferably, an installation opening is also provided on the second barrel cover. A float is provided in the installation opening. The float moves up and down following the water level in the lower barrel. When the water level in the lower barrel reaches the preset water storage capacity, the float extends out of the installation opening, and the position information of the float can be observed through the side wall and the bottom wall of the upper barrel. The float changes its position by using the buoyancy provided by water when it contacts water, so as to be exposed in the installation opening or change its position in the installation opening, and the position of the float is observed through the transparent side wall and bottom wall of the upper barrel to determine the water level in the lower barrel, and the water can be poured in time according to the position of the float.

[0012] Preferably, a disassembly switch is provided between the upper barrel and the lower barrel or the support ring. The upper end of the disassembly switch is rotatably connected to the lower end of the upper barrel, and the lower end of the disassembly switch is buckled with the lower barrel or the support ring to realize the fixation and disassembly separation of the upper barrel and the lower barrel.

[0013] Preferably, a support column is provided at the lower end of the upper barrel. The support column is in abutting cooperation with the support ring or the second barrel cover. When the upper barrel and the lower barrel are disassembled, the support column stably supports the upper barrel on the ground. Since the support area between the support ring and the upper barrel is limited, and the disassembly switch extends out from the bottom of the upper barrel, the provision of the support column increases the cooperation area, stably supports the upper barrel with a certain weight after adding clean water on the lower barrel through the middle and the periphery, and can also support the upper barrel on the ground through the support column without changing the position of the disassembly switch after the upper barrel is disassembled.

[0014] Preferably, the pumping device includes a pumping water pump, a pumping gear, a pumping wheel, and a water spraying head. The pumping gear is disposed between the cleaning area and the purified water area. An eccentric position of the pumping wheel is movably connected to a pumping connecting rod, and the other end of the pumping connecting rod is movably connected to the water pump core of the pumping water pump. A first rack is provided in the length direction of the mop head of the flat mop. When the mop head passes through the cleaning port, the first rack can mesh with the pumping gear. The up-and-down movement of the mop head can drive the pumping water pump to pump water through the pumping gear, the pumping wheel, and the pumping connecting rod. The water spraying head and the pumping gear are located in different directions of the cleaning port. The water spraying head is connected to the pumping water pump through a pumping water path. A water spraying port is provided on the water spraying head, and the water spraying port can spray the water pumped by the pumping water pump onto the wiping object.

[0015] Preferably, a sunken platform is provided at the bottom of the purified water area, and the pumping water pump is located in the sunken platform. The lower end of the sunken platform is flush with the lower end of the support column to jointly support the upper bucket on the second bucket cover or the ground. The setting of the sunken platform makes the pumping water pump located at the lowest position in the purified water area, and most of the water in the purified water area can enter the pumping water pump and be discharged for cleaning. Moreover, the sunken platform can also play the same supporting role as the support column.

[0016] The advantages of the present utility model are as follows: Generally, an existing mop bucket separately sets a region inside the bucket body to form a purified water area, and the regions outside the purified water area of the bucket body form a cleaning area and a sewage area. Under this partition setting, setting the position of the mop bucket in the purified water area to be transparent alone has high injection molding production difficulty and high cost. If the entire mop bucket is set to be transparent, the position of the sewage area can also be observed from the outside, and the dirt in the sewage area affects the aesthetics; in the mop bucket of the present utility model, the position distribution of areas such as the purified water area is changed, the purified water area is separately set to be transparent so that the amount of purified water can be visualized, and the sewage area is made of an opaque material, and it will not affect the aesthetics due to the external penetration of dirt; and the upper bucket and the lower bucket are detachably connected. When adding water and draining water, there is no need to move the entire mop bucket. The upper bucket can be separately moved to add purified water and the lower bucket can be separately moved to pour out sewage, making the water addition and drainage more convenient;

[0017] To reduce the volume of the mop bucket to reduce 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 surrounding frame is adapted to the flat mop, and the volume of the first sewage area is smaller than the volume of the second sewage area. A water passing channel is provided on the side or bottom of the surrounding frame to discharge the sewage in the first sewage area to the second sewage area to increase the overall capacity of the sewage area.

[0027] Such as Figure 1-7, A flat mop device with visible water volume, comprising a flat mop 1 and a mop bucket 2. The mop bucket 2 includes a detachable upper bucket 3 and a lower bucket 4. One side of the upper bucket 3 is vertically penetrated to form a cleaning area 5, and the other side is provided with a clean water area 6 separated from the cleaning area 5. The flat mop 1 enters the cleaning area 5 downward. The clean water area 6 sprays water to the cleaning area 5 through a pumping device 7 for the flat mop 1 to clean. The sewage generated in the cleaning area 5 flows downward into the lower bucket 4. The lower bucket 4 is provided with a surrounding frame 8 below the cleaning area 5. The surrounding frame 8 blocks the water in the lower bucket 4 from entering the cleaning area 5. The upper bucket 3 is made of a transparent material to observe the remaining water volume in the clean water area 6 from the side wall of the upper bucket 3.

[0028] Specifically, the upper bucket 3 is integrally injection-molded from transparent plastic, and a partition 9 is integrally formed between the cleaning area 5 and the clean water area 6 for separation. The position of the cleaning area 5 is vertically penetrated, and the position of the clean water area 6 is open at the top, and the rest of the directions are enclosed to form a water-containing cavity. The lower bucket 4 is integrally formed from ordinary opaque plastic, and the top is open to connect to the upper bucket 3 and communicate with the upper bucket 3. The cleaning and water squeezing of the flat mop 1 are both carried out in the cleaning area 5. During cleaning, the pumping device 7 sprays the clean water in the clean water area 6 onto the flat mop 1. The sewage generated by the cleaning and water squeezing of the flat mop 1 flows downward into the lower bucket 4. The length of the flat mop 1 is slightly less than the height of the cleaning area 5, so that the wiping object suitable for the flat mop 1 can be cleaned and water-squeezed as a whole. In this embodiment, the clean water area 6 is entirely located on one side of the upper bucket 3. The area of the lower bucket 4 except the surrounding frame 8 forms a sewage area. After the upper bucket 3 and the lower bucket 4 are connected, the surrounding frame 8 is located directly below the cleaning area 5 and communicates with the cleaning area 5. When the flat mop 1 enters the cleaning area 5 downward, the lower end of the flat mop 1 is located in the surrounding frame 8. The setting of the surrounding frame 8 reduces the contact between the lower end of the flat mop 1 and the sewage in the lower bucket 4.

[0029] The existing mop bucket generally has a separate area in the barrel body to form a clean water area, and the barrel body forms a washing area and a sewage area in the area outside the clean water area. Under this zoning setting, the position of the mop bucket in the clean water area is separately set to be transparent, that is, the side wall of the clean water area is made of transparent plastic, and the other areas are made of ordinary opaque plastic. The transparent and opaque parts of the barrel body are injection molded separately, and then the two are processed into one body. The injection molding production is difficult and the cost is high. If the mop bucket is set to be transparent as a whole, the position of the sewage area can also be observed from the outside. If the mop bucket is not cleaned in time, the dirt will adhere to the barrel body and is difficult to clean, and it can be seen from the outside. The dirt in the bucket makes the experience poor; the mop bucket 2 in the utility model changes the position distribution of the water purification zone 6 and other areas, so that the water purification zone 6 is separately set to be transparent so that the amount of purified water can be seen, and the sewage zone is made of opaque material, and the appearance will not be affected by the dirt outside, so that the amount of purified water can be seen and the dirt in the sewage zone will not affect the appearance. The utility model can take into account the visualization of the amount of purified water and the fact that the dirt in the sewage zone does not affect the appearance. During production, the steps of separately injecting the upper bucket 3 and the lower bucket 4 are added, and the production difficulty is not increased; and the upper bucket 3 and the lower bucket 4 are detachably connected, and 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 purified water and the lower bucket 4 can be moved separately to pour out sewage, making adding water and draining water easier.

[0030] Preferably, the upper bucket 3 is provided with a first bucket cover 10, and the first bucket cover 10 is provided with a cleaning port 11 and a water injection port 12 at positions corresponding to the cleaning area 5 and the water purification area 6, respectively. The cleaning port 11 is provided with a squeezing device 13 at a position away from the water purification area 6 and the water injection port 12. The flat mop 1 enters the cleaning area 5 and cooperates with the squeezing device 13 to clean or squeeze. Figure 5 The cleaning area 5 and the water purification area 6 are located on the left and right sides respectively, separated by a partition 9 in the middle. The squeezing device 13 is located on the left side of the cleaning area 5, away from the water purification area 6. When the flat mop 1 is cleaning and squeezing water, the wiped object is on the left side, away from the direction of the water purification area 6. Even if some sewage splashes upward during cleaning and squeezing water, it will not enter the water purification area 6.

[0031] The squeezing device 13 in this embodiment includes a movable scraper 14 and a supporting wheel 15 opposite to the scraper 14. The supporting wheel 15 and the scraper 14 jointly clamp the flat mop 1 to increase the resistance between the wiping object and the scraper 14 to achieve cleaning and squeezing. The scraper 14 is movably arranged to adjust the resistance when the flat mop 1 leaves the cleaning area 5 upward to prevent the flat mop 1 from lifting the mop bucket 2 as a whole. The supporting wheel 15 is rotatably installed on the first bucket cover 10, and can be rotated when the flat mop 1 moves up and down to reduce the resistance of the flat mop 1.

[0032] like Figure 3 , Figure 5, the surrounding frame 8 divides the lower barrel 4 into a first sewage area 16 and a second sewage area 17, and there is a water passing channel 18 between the surrounding frame 8 and the lower barrel 4. The sewage generated in the cleaning area 5 flows downward into the first sewage area 16, and the sewage in the first sewage area 16 enters the second sewage area 17 through the water passing channel 18 to achieve the liquid level balance between the first sewage area 16 and the second sewage area 17. In order to reduce the volume of the mop bucket 2 and thus reduce the 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 surrounding frame 8 is adapted to the flat mop 1, and the volume of the first sewage area 16 is smaller than that of the second sewage area 17. The water passing channel 18 is arranged on the side or bottom of the surrounding frame 8 to discharge the sewage in the first sewage area 16 into the second sewage area 17 to increase the overall capacity of the sewage area.

[0033] As Figure 5 , in this embodiment, the surrounding frame 8 is detachably installed in the lower barrel 4 and divides the lower barrel 4 into a first sewage area 16 on the right side and a second sewage area 17 on the left side. Figure 6 There is a gap between the upper and lower sides of the surrounding frame 8 and the side wall of the lower barrel 4, and this gap forms the water passing channel 18. The sewage generated in the cleaning area 5 flows downward to the first sewage area 16 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, and the sewage automatically flows through the water passing channel 18 into the second sewage area 17 to make the liquid levels of the two sewage areas level.

[0034] As Figure 2 , Figure 4 and Figure 6 , there is a support ring 19 on the inner side of the barrel mouth of the lower barrel 4. The support ring 19 is provided with a first step 20 and a second step 21, and the bottom of the upper barrel 3 is provided with a third step 22 and a fourth step 23. The third step 22 and the fourth step 23 are respectively supported on the first step 20 and the second step 21. If the upper barrel 3 is directly installed on the lower barrel 4, the lower barrel 4 needs to have an outward flared opening to accommodate the insertion of the upper barrel 3, or an inward step is provided at the barrel mouth of the lower barrel 4, but setting this step increases the production difficulty. The setting of the support ring 19 forms a support between the upper and lower barrels 4, and the support ring 19 can also increase the aesthetic appearance of the mop bucket 2.

[0035] Preferably, as Figure 3 , Figure 4 , the support ring 19 extends inwards to form a second barrel cover 24. The second barrel cover 24 is provided with a water inlet 25 below the squeezing device 13. The surrounding frame 8 is fixed on the second barrel cover 24, and the surrounding frame 8 can be detached from the lower barrel 4 together with the support ring 19 / second barrel cover 24. The second barrel cover 24 covers the sewage area to prevent the sewage from contacting the bottom surface of the upper barrel 3 and making the bottom surface of the upper barrel 3 dirty when the sewage in the sewage area is relatively full, and can also prevent the sewage from sloshing out when the lower barrel 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 Figure 4 , in this embodiment, an installation opening 26 is further provided on the second bucket cover 24, and a buoy 27 is provided in the installation opening 26. The buoy 27 moves up and down following the water level in the lower bucket 4. When the water level in the lower bucket 4 reaches the preset water storage capacity, the buoy 27 extends out of the installation opening 26, and the position information of the buoy 27 can be observed through the side wall and bottom wall of the upper bucket 3. When the water level in the sewage area is low and the water does not contact the buoy 27, the buoy 27 is located below the installation opening 26, and the position of the buoy 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 makes the buoy 27 move upward into or extend out of the installation opening 26, and the position information of the buoy 27 can be observed through the side wall and bottom wall of the upper bucket 3. By distinguishing the position of the buoy 27, the real-time water level in the sewage area can be judged without disassembling the upper bucket 3 and the second bucket cover 24 to observe the water level, which is more convenient to use. Of course, it is also possible that the buoy 27 is located at the lower position of the installation opening 26 when the water level is low, and the buoy 27 is located at the upper position of the installation opening 26 when the water level is high, and the real-time water level is judged 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 Figure 1 、 Figure 2 and Figure 6 , a disassembly switch 28 is provided between the upper bucket 3 and the lower bucket 4 or the 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 buckled with the lower bucket 4 or the support ring 19 to realize the fixation and disassembly separation of the upper bucket 3 and the lower bucket 4. Of course, the disassembly switch 28 can also be rotatably connected to the lower bucket 4 or the support ring 19, and the disassembly switch 28 is rotated upward to be buckled and fixed with the lower end of the upper bucket 3.

[0039] Preferably, disassembly switches 28 are provided on both opposite sides of the mop bucket 2 to realize the balanced fixation of both sides of the mop bucket 2.

[0040] As Figure 3 and Figure 6 , a support column 29 is provided at the lower end of the upper bucket 3. The support column 29 is in abutting cooperation with 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 stably supports the upper bucket 3 on the ground.

[0041] In the above embodiment, as Figure 2 、 Figure 3 and Figure 7, the water pumping device 7 includes a water pumping pump 30, a water pumping gear 31, a water pumping wheel 32 and a water spray head 33. The water pumping gear 31 is arranged between the cleaning area 5 and the purified water area 6. An eccentric position of the water pumping wheel 32 is movably connected with a water pumping connecting rod 34, and the other end of the water pumping connecting rod 34 is movably connected with the water pump core of the water pumping pump 30. A first rack 35 is arranged along the length direction of the mop head of the flat mop 1. When the mop head passes through the cleaning opening 11, the first rack 35 can be engaged with the water pumping gear 31. The up and down movement of the mop head can drive the water pumping pump 30 to pump water through the water pumping gear 31, the water pumping wheel 32 and the water pumping connecting rod 34. The water spray head 33 and the water pumping gear 31 are in different directions with respect to the cleaning opening 11. The water spray head 33 is connected with the water pumping pump 30 through a water pumping waterway 36. A water spray opening 37 is arranged on the water spray head 33, and the water spray opening 37 can spray the water pumped by the water pumping pump 30 onto the wiping object.

[0042] Preferably, as Figure 6 , a sunken platform 38 is arranged at the bottom of the purified water area 6. The water pumping pump 30 is located in the sunken platform 38. The lower end of the sunken platform 38 is flush with the lower end of the support column 29 to jointly support the upper barrel 3 on the second barrel cover 24 or the ground.

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