Description

Technical Field

[0001] The utility model relates to a mop bucket, in particular to a floating function indicator device of the mop bucket and the mop bucket. Background Art

[0002] Mop buckets are essential household cleaning tools. Available mop buckets come in a wide variety of styles and functions. Rotating mop buckets and mops are among the most popular household items that have emerged in recent years, making them convenient for mopping. These are generally categorized as foot-operated, pressure-operated, or electric-powered, each using a foot-operated, hand-operated, or electric-powered mechanism to rotate the cleaning mechanism within the mop bucket. For example, a manual-powered mop, for example, is placed in the mop bucket, and the mop handle is manually pressed downward for rotational cleaning and spin-drying. The handle consists of an inner and outer rod that can rotate relative to each other and be shortened or extended. The mop bucket is equipped with a support mechanism for the mop head, which rotates. Pulling the mop handle up and down causes the mop head to rotate at high speed, achieving both cleaning and spin-drying.

[0003] The existing mop bucket structure generally includes a clean water chamber and a dirty water chamber. The pumping mechanism is arranged in the clean water chamber. When the mop is placed in the mop bucket and rotated, the pumping mechanism is driven by the mop to supply water to the rotating mop. However, when dehydration is required, the water in the clean water chamber generally needs to be used up before dehydration can be performed.

[0004] In order to solve the above problem, there is a method of providing a water storage chamber in the clean water chamber to accommodate the water required for one cleaning cycle for water supply during cleaning. When the water in the water storage chamber is used up, the system switches to a dehydration mode. For example, patent CN215687584U discloses a self-drying mop bucket and a cleaning tool having the mop bucket, which includes a barrel body, a closed loop extending upward from the bottom of the barrel body, a sewage chamber for accommodating sewage is formed between the barrel body and the closed loop, and a partition is provided in the closed loop to separate the closed loop. The closed loop is composed of a clean water chamber at the upper end and a water containing part at the lower end which can accommodate the amount of water required for a cleaning cycle. A cover which can open or close the clean water chamber is provided above the closed loop. A pumping mechanism which can drive the rotating mop head to rotate on the cover and can pump water in the water containing part out of the cover is provided in the water containing part. A seepage hole which connects the clean water chamber and the water containing part is provided on the partition. An air replenishing hole which replenishes air when the water in the water containing part is pumped out is provided on the water containing part. The water pumping of the pumping structure is controlled by the rotation of the rotating mop head.

[0005] The above-mentioned mop bucket is provided with a water holding portion that can accommodate the amount of water required for one cleaning cycle. When the mop is placed in the mop bucket and rotates, it drives a pumping mechanism to pump water. The pumping mechanism transfers the water in the water holding portion to the mop for cleaning. When the water in the water holding portion is used up or is insufficient to supply the mop, the mop is dehydrated. However, during use, it is difficult for the user to distinguish whether the mop is in a cleaning state or a dehydrating state, which affects the user's operation. Utility Model Content

[0035] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely illustrative and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0036] It should be noted that like reference numerals denote like items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.

[0037] Figures 1-13 As shown, the mop bucket includes a bucket body 1, which is provided with a clean water chamber 22 and a sewage chamber 43. Preferably, an inner bucket 2 with an upward opening is installed in the bucket body 1. The inner bucket 2 has a clean water chamber 22 for storing clean water, and the inner cavity of the bucket body 1 itself serves as the sewage chamber 43 for storing sewage generated after mop washing. The inner cavity of the inner bucket 2 is used to serve as the clean water chamber 22 for storing clean water.

[0038] Figure 2 、 Figure 3As shown, the inner bucket 2 is detachably mounted in the barrel body 1. Preferably, the inner bucket 2 includes a main body 9 with an upward opening and a cavity therein, a frame 14 located above the main body 9, and connecting ribs 10 connecting the frame 14 and the edge of the opening of the main body 9. The cavity inside the main body 9 serves as the above-mentioned water purification chamber 22. A cover 6 is provided above the main body 9 to open or close the water purification chamber 22. The mop can be placed on the cover 6 and rotated for cleaning or dehydration. A plurality of connecting ribs 10 are evenly arranged on a circle around the opening edge of the main body 9. Drainage outlets 11 are formed between adjacent connecting ribs 10. The plurality of drainage outlets 11 surround the cover 6 to allow sewage generated by mop cleaning or dehydration to flow into the sewage chamber 43. A circle of downwardly extending insertion portions 15 is provided on the outer edge of the frame 14. A circle of upwardly opening insertion grooves 16 is provided on the opening edge of the barrel body 1. The insertion portions 15 are downwardly inserted into the insertion grooves 16 to fix the inner bucket 2 in the barrel body 1.

[0039] The barrel body 1 is also provided with a water holding chamber 65 and a pumping mechanism that can accommodate the amount of water required for one cleaning cycle. The clean water chamber 22 flows water into the water holding chamber 65. The pumping mechanism pumps water out of the water holding chamber 65 for cleaning the mop placed in the barrel body 1. The pumping of water by the pumping mechanism is controlled by the rotation of the rotating mop head 67 of the mop.

[0040] Figure 9 、 Figure 10 As shown, a floating indicator 3 is further provided in the barrel body 1 , and the indicator 3 is connected to the water chamber 65 . The indicator 3 floats up and down as the water level in the water chamber 65 rises and falls to reflect the change in the water volume in the water chamber 65 .

[0041] For example, before use, the water chamber 65 contains the amount of water required for one cleaning cycle of the mop. At this time, the indicator 3 is at a first height, and the mop is placed in the mop bucket for rotational cleaning. During the cleaning process, the water in the water chamber 65 is gradually pumped out by the pumping mechanism, causing the height of the indicator 3 to gradually decrease as the amount of water decreases. When the height of the indicator 3 decreases to a second height, it means that the water in the water chamber 65 is used up or insufficient to supply the mop. At this time, the mop is rotating and dehydrating in the mop bucket. The user can judge whether there is water in the water chamber 65 based on the floating height of the indicator 3, and thus judge whether the mop placed in the mop bucket is in a cleaning state or a dehydrating state, which is convenient for the user to operate.

[0042] Figure 4As shown, the water holding chamber 65 includes a main chamber 44 located at the bottom of the water purification chamber 22. Water flows from the water purification chamber 22 into the main chamber 44. The pumping mechanism includes an impeller 28 rotatably disposed within the main chamber 44. A rotating support member 5 extending vertically upward from the main chamber 44 is provided within the barrel body 1. The lower end of the rotating support member 5 is connected to the impeller 28. The upper end of the rotating support member 5 passes through the cover 6 to support the mop. When the rotating mop head 67 of the mop is placed in the inner barrel 2 for rotational cleaning or dehydration, the upper end of the rotating support member 5 engages with the rotating mop head 67 in a limited manner. The rotating support member 5 and the impeller 28 are driven to rotate by the rotating mop head 67. During the rotation of the rotating mop head 67, the impeller 28 rotates within the main chamber 44 to pump water out for cleaning by the rotating mop head 67. The cover 6 has a hole 4 at the center for the upper end of the rotating support member 5 to extend.

[0043] The rotation of the rotating support 5 is driven by the rotating mop head 67. The rotating structure of the rotating mop head 67 is a conventional structure of existing mops. For example, Patent CN211484438U discloses a cleaning tool in which the mop includes a mop rod and a mop head. The mop rod includes an inner rod and an outer rod. The inner rod and the outer rod are rotatable relative to each other and can be compressed or extended. When the mop head is restrained on the support device, pulling the mop rod up and down can drive the mop head to rotate at high speed.

[0044] The structure of the rotating mop head 67 driving the rotating support member 5 to rotate is also a conventional structure in the field. For example, a second slot 66 for the rotating support member 5 to be inserted into the bottom of the rotating mop head 67 is provided. After the rotating support member 5 is inserted into the second slot 66 at the bottom of the mop, the top of the rotating support member 5 and the second slot 66 cooperate with the teeth and grooves to limit the relative rotation of the rotating mop head 67 and the rotating support member 5, so that when the rotating mop head 67 rotates, it can drive the rotating support member 5 to rotate synchronously, and then the rotation of the rotating support member 5 drives the impeller 28 to work.

[0045] Figure 6 、 Figure 7 As shown, preferably, a concave groove 26 is provided at the bottom of the water purification chamber 22 , and an upper cover 24 is provided on the groove 26 . The upper cover 24 and the groove 26 are enclosed to form the main chamber 44 .

[0046] Specifically, a circle of edges of the groove 26 extends upward and protrudes from the bottom of the clean water chamber 22. The bottom of the clean water chamber 22 is located on the outside of the edge of the groove 26 and is provided with a circle of convex edges 29. The convex edges 29 surround the outside of the edge of the groove 26 and are combined with the edge of the groove 26 to form a ring-shaped first slot 30. The bottom of the upper cover 24 is provided with a circle of convex edges 31 that are adapted to the shape of the first slot 30. The convex edges 31 are inserted into the first slot 30 to position the upper cover 24. The upper cover 24 is fixed to the bottom of the clean water chamber 22 by screws. In addition, the structure of the convex edges 31 inserted into the first slot 30 also improves the sealing between the upper cover 24 and the bottom of the clean water chamber 22.

[0047] Connected to the water chamber 65 is a water outlet pipe 23 that communicates with the cover 6 and allows water to be discharged from the water chamber 65. Preferably, the water outlet pipe 23 is fixed to the upper cover 24 and extends vertically upward. The bottom of the cover 6 is provided with an interface that communicates with the upper surface of the cover 6. The upper end of the water outlet pipe 23 is tightly inserted into the interface. The water outlet pipe 23 is integrally formed with the upper cover 24.

[0048] When the impeller 28 rotates in the water chamber 65 , the water in the water chamber 65 is transported from the water outlet pipe 23 to the cover 6 , so as to clean the rotating mop head 67 placed above the cover 6 and rotating.

[0049] In addition, the water chamber 65 is connected to an air-injection hole. When the water in the water chamber 65 is pumped out, air is injected through the air-injection hole to balance the air pressure in the water chamber 65. Preferably, the air-injection hole is provided on the upper cover 24. The air-injection pipe 25 is connected to the air-injection hole. The air-injection pipe 25 extends vertically upward and is connected to the top of the pipe. The cover 6 is provided with a through hole 8 connecting the upper and lower surfaces. The connector is inserted into the through hole 8 to communicate with the external atmospheric environment.

[0050] A one-way valve may be provided in the air supply pipe 25 to restrict air from flowing from the outside to the water containing chamber 65 , thereby preventing water from being discharged from the air supply pipe 25 when the impeller 28 rotates.

[0051] Figure 4 As shown, preferably, an upwardly protruding water barrier 7 is provided in the middle position of the top of the cover 6, and the above-mentioned holes 4 and through holes 8 are both provided on the water barrier 7 to prevent sewage from flowing into the holes 4 and through holes 8 along the top plate surface of the cover 6 when the mop is cleaned or dehydrated.

[0052] Figure 8 、 Figure 11-13As shown, the sealing or connection between the clean water chamber 22 and the water holding chamber 65 is controlled by the lifting and lowering of the rotating support member 5. The rotating support member 5 can be raised and lowered relative to the main chamber 44 and the impeller 28. A return spring 35 is provided in the main chamber 44, and the two ends of the return spring 35 are supported on the rotating support member 5 and the impeller 28, respectively. When the mop is placed on the rotating support member 5, the rotating support member 5 moves downward under the action of the mop's gravity, sealing the clean water chamber 22 and the main chamber 44, and stopping the clean water chamber 22 from flowing into the water holding chamber 65. When the mop is removed from the rotating support member 5, the return spring 35 pushes the rotating support member 5 upward to its initial position, connecting the clean water chamber 22 and the main chamber 44, thereby allowing the water in the clean water chamber 22 to flow into the water holding chamber 65.

[0053] The reset spring 35 is supported on the rotating support 5 and the impeller 28. Since the impeller 28 and the rotating support 5 rotate synchronously, the reset spring 35 will not hinder the rotation of the impeller 28 and the rotating support 5, so that the impeller 28 rotates more smoothly, thereby making the water supply from the water chamber 65 to the mop smoother, and making the up and down floating of the indicator 3 more obvious, making it easier for users to understand the changes in the water amount in the water chamber 65, and the indication is more accurate.

[0054] A shaft extending vertically upward is provided at the bottom of the main chamber 44 , and the impeller 28 and the rotating support member 5 are both sleeved on the shaft and rotate around the axis of the shaft.

[0055] The shaft body includes a fixed shaft 56, a sleeve 54 sleeved on the head of the fixed shaft 56, and a cylinder 61 extending from the bottom of the main cavity 44. The sleeve 54 is axially fixed relative to the fixed shaft 56 and can rotate relative to the fixed shaft 56. A ball 55 is provided between the upper end surface of the fixed shaft 56 and the sleeve 54. The lower end of the fixed shaft 56 is inserted into the center of the cylinder 61 and fixed.

[0056] Impeller 28 comprises a base plate 36, a central sleeve 38 positioned at the center of base plate 36, an outer ring sleeve 39 surrounding the central sleeve 38, and a plurality of blades 37 arranged on the outer circumference of the outer ring sleeve 39. The blades 37, central sleeve 38, and outer ring sleeve 39 are all integrally formed on base plate 36. Central sleeve 38 fits over cylinder 61. The upper end of central sleeve 38 is provided with an inwardly folded annular abutment 62, which abuts against the upper end surface of cylinder 61. The fixed shaft 56 passes through the center of the annular bottom edge. A gap is provided between base plate 36 and the bottom of main chamber 44 to facilitate smooth rotation of impeller 28.

[0057] The rotating support member 5 is located on the upper part of the impeller 28 and is sleeved on the shaft body for rotation. The bottom of the rotating support member 5 has a sleeve groove 53 with an opening downward. The rotating support member 5 is sleeved on the outside of the shaft sleeve 54 through the sleeve groove 53 and can move up and down relative to the shaft sleeve 54. The bottom of the outer peripheral side wall of the rotating support member 5 is evenly provided with a plurality of sliding protrusions 33. The inner wall of the outer ring sleeve 39 is provided with a plurality of plug-in grooves 40 corresponding to the sliding protrusions 33. The plurality of sliding protrusions 33 can be slid up and down and inserted into the corresponding plug-in grooves 40, so that the rotating support member 5 When rotating, the impeller 28 is driven to rotate and is not affected by the up and down movement of the rotating support 5. The reset spring 35 is sleeved on the outside of the central sleeve 38 and is located between the central sleeve 38 and the outer ring sleeve 39. The upper end of the reset spring 35 is supported on the bottom of the rotating support 5, and the lower end of the reset spring 35 is supported on the bottom plate 36. An annular step three 59 is provided in the main cavity 44. When the reset spring 35 pushes the rotating support 5 to move up and return to the initial position, the sliding protrusion 33 abuts on the annular step three 59, limiting the rotating support 5 from continuing to move up.

[0058] Preferably, the sliding protrusion 33 extends downward to form an accommodating area for accommodating the upper end of the return spring 35 .

[0059] A boss 27 formed by stacking multiple layers of columns is formed on the upper cover 24. The diameter of the columns decreases from bottom to top. Multiple levels of channels with different diameters are provided in the multi-layer boss 27. The diameter of the channels decreases from bottom to top. Adjacent channels are transitioned by the above-mentioned annular step 59. The rotating support member 5 extends upward through the channels and extends into the water chamber 65.

[0060] Preferably, a boss 27 formed by superimposing two layers of columns is formed on the upper cover 24, and two-level channels are formed in the boss 27, including a first channel 60 located below and opposite to the groove 26, and a second channel 58 located above and connected to the top surface of the boss 27. The upper half of the above-mentioned outer ring sleeve 39 is inserted into the first channel 60, and the upper end edge of the outer ring sleeve 39 is opposite to the annular step three 59 between the first channel 60 and the second channel 58. When the rotating support member 5 is in the initial position, the sliding protrusion 33 is in the first channel 60 and opposite to the annular step three 59 between the first channel 60 and the second channel 58, which is used to limit the rotating support member 5.

[0061] In addition, a water inlet channel 57 connected to the water containing chamber 65 is provided in the rotating support member 5, and a plurality of water inlets 32 connected to the water inlet channel 57 are provided on the circumferential side wall of the rotating support member 5. When the rotating support member 5 is in the initial position, the water inlet 32 is located above the boss 27 so that the water inlet channel 57 connects the clean water chamber 22 and the water containing chamber 65. At this time, the water in the clean water chamber 22 can enter the water containing chamber 65 through the water inlet channel 57. When the mop is placed on the rotating support member 5, the rotating support member 5 moves downward under the action of the gravity of the mop, so that the water inlet 32 moves down to the channel of the boss 27, closing the water inlet 32. At this time, water stops flowing from the clean water chamber 22 to the water containing chamber 65.

[0062] Preferably, the sleeve groove 53 includes a first sleeve groove 63 sleeved on the outside of the cylinder 61 and a second sleeve groove 64 sleeved on the outside of the shaft sleeve 54. The first sleeve groove 63 has a slot located at the bottom of the rotating support 5. A plurality of channel grooves are opened on the inner groove wall of the first sleeve groove 63. The plurality of channel grooves are arranged in a circular array with the axis of the rotating support 5 as the center. The lower ends of the plurality of channel grooves are connected to the bottom of the rotating support 5. The plurality of channel grooves are combined to form the above-mentioned water inlet channel 57. The circumferential side wall of the rotating support 5 is provided with a water inlet 32 that is connected to each channel groove one by one.

[0063] In order to improve the air tightness between the clean water chamber 22 and the water containing chamber 65 when the rotating support 5 moves downward, a sealing ring 34 is fixed on the outer wall of the rotating support 5. The sealing ring 34 is located above the water inlet 32. When the rotating support 5 moves downward, the sealing ring 34 is spaced between the inner wall of the second channel 58 and the outer wall of the rotating support 5 to achieve sealing.

[0064] Figure 13 As shown, the working principle of the mop being placed in the mop bucket for dehydration and cleaning is as follows: when the rotating mop head 67 of the mop is placed on the rotating support 5, and the upper end of the rotating support 5 is inserted into the second slot 66 at the bottom of the rotating mop head 67, the rotating support 5 moves downward due to the gravity of the mop to close the water inlet 32. At this time, the clean water chamber 22 stops flowing water into the water containing chamber 65, and the water in the clean water chamber 22 cannot enter the water containing chamber 65 from the water inlet 32. The rotating mop head 67 rotates to drive the rotating support 5 to rotate, and the rotating support 5 then rotates to drive the impeller 28 in the water containing chamber 65 to rotate and pump water. The impeller 28 transports the water in the water containing chamber 65 to the cover 6 through the outlet pipe 23 to clean the rotating mop head 67 during the rotation process. When the water in the water containing chamber 65 is used up, the mop is switched from the cleaning mode to the dehydration mode, and the rotating mop head 67 continues to rotate and dry.

[0065] When the mop is taken out of the mop bucket and the upper part of the rotating support member 5 loses force, the return spring 35 pushes the rotating support member 5 upward, so that the water inlet 32 moves back to the upper part of the boss 27. At this time, the water inlet 32 is opened, and the clean water in the clean water chamber 22 can flow from the water inlet 32 through the water inlet channel 57 into the water containing chamber 65, replenishing the water in the water containing chamber 65 to prepare for the next mop cleaning.

[0066] Figure 8 As shown, the above-mentioned channel groove is located at the groove at the bottom of the rotating support 5 and is opposite to the pipe opening at the upper end of the outer ring sleeve 39. The side wall of the outer ring sleeve 39 is provided with a first water outlet 41 for water entering the outer ring sleeve 39 to flow to other places of the external water holding chamber 65. A first water outlet 41 is provided between two adjacent blades 37, and a second water outlet 42 is provided on the bottom plate 36 to communicate with its lower surface. The number of the second water outlets 42 is the same as that of the first water outlets 41. The second water outlets 42 are located below the internal pipe of the outer ring sleeve 39. The clean water in the clean water chamber 22 enters the water inlet channel 57 from the water inlet 32, and then enters the outer ring sleeve 39 from the water inlet channel 57. After passing through the outer ring sleeve 39, the water flows from the first water outlet 41 and the second water outlet 42 to the surrounding and bottom of the impeller 28 respectively, so that the water can fill the water holding chamber 65.

[0067] The water containing chamber 65 includes a water containing channel 52 connected to one side of the main chamber 44 . The water containing channel 52 is communicated with the main chamber 44 . The indicator 3 is connected to the water containing channel 52 , and the indicator 3 floats up and down as the amount of water in the water containing channel 52 changes.

[0068] Figure 9 、 Figure 10 As shown, the frame 14 is provided with an exposure opening 17, and the indicator 3 located below the frame 14 extends upward from the exposure opening 17 for observation. The indicator 3 extends from the exposure opening 17 to facilitate the user to observe when the water volume in the water chamber 65 changes.

[0069] Specifically, the bottom of the inner barrel 2 is provided with a downwardly protruding lower convex portion 13, and a water pipe 12 is connected to the lower convex portion 13. A water channel 52 is formed in the water pipe 12. The water pipe 12 includes a horizontal pipe 45 whose one end is connected to the lower convex portion 13 and extends from the bottom of the inner barrel 2, and a vertical pipe 47 connected to the other end of the horizontal pipe 45 and located below the frame 14. The vertical pipe 47 is located on one side of the lateral side of the main body 9 of the inner barrel 2 and is below the frame 14. The upper end of the vertical pipe 47 is opposite to the exposure port 17. The indicator 3 is a float rod connected to the vertical pipe 47. The upper end of the float rod extends from the upper end of the vertical pipe 47 and passes through the exposure port 17 to be exposed above the frame 14.

[0070] The water pipe 12 is arranged outside the inner barrel 2, and the mop is placed inside the inner barrel 2 and rotates, so that the arrangement of the float rod will not affect the rotation, cleaning and dehydration of the mop.

[0071] Figure 5 As shown, the side of the lower protrusion 13 is provided with a first joint 21 connected to the main cavity 44, one end of the horizontal tube 45 is plugged and fixed to the first joint 21, the other end of the horizontal tube 45 is provided with a vertical second joint 46, the lower end of the vertical tube 47 is plugged and fixed to the second joint 46, and the bottom of the frame 14 is provided with a positioning portion 20 for the upper end of the vertical tube 47 to be inserted, and the upper end of the vertical tube 47 is inserted into the positioning portion 20 for positioning, so that the upper end of the vertical tube 47 is connected to the exposed opening 17.

[0072] Preferably, a vertical extension portion 18 extending downward is provided on the inner side of the frame 14, and a plurality of raised ribs 19 are provided on the bottom of the frame 14. The plurality of raised ribs 19 and the vertical extension portion 18 enclose a portion for inserting the upper end of the vertical tube 47, and the exposure port 17 is located in this portion.

[0073] In addition, two sections of channels with different diameters are provided in the vertical pipe 47, which are located in the lower channel 49 and the upper channel 51 located above the lower channel 49. The upper channel 51 is connected to the top of the lower channel 49. The diameter of the lower channel 49 is larger than the diameter of the upper channel 51. The upper channel 51 and the lower channel 49 are transitioned by an annular step 1 50. An annular step 2 48 is provided on the float rod. During the floating process of the float rod, the annular step 2 48 can abut against the annular step 1 50 to limit the upward movement of the float rod, thereby preventing the float rod from upwardly detaching from the vertical pipe 47.

[0074] Preferably, the lowest point of the water containing channel 52 is flush with the lowest point of the main cavity 44 , so that the water level in the water containing channel 52 and the water level in the main cavity 44 change synchronously, so that the float rod can achieve a more accurate detection effect.
