Description

Technical Field

[0001] The invention relates to a cleaning tool, in particular to a dirt-removing and separating mop cleaning bucket suitable for cleaning and drying a hand-operated rotating flat mop. Background Art

[0002] To this end, the applicant invented a utility model patent application with patent number CN201720525401.8 (publication number CN207785091U) entitled "A Water-Saving Mop Bucket", which discloses a non-lifting cleaning and drying bucket, including a barrel body, a transmission shaft for supporting a mop head with a wiping material at the bottom of the barrel body, and the transmission shaft can rotate the mop head placed thereon, characterized in that: an inwardly concave accommodating cavity is provided at the bottom of the barrel body, a box body is embedded in the accommodating cavity, a water pump and a control structure are provided in the box body, and a cleaning component is also provided in the barrel body for cleaning the wiping material at the bottom of the mop head rotating in the barrel body, and the water pump is controlled by the control structure to spray water toward the wiping material at the bottom of the mop head. In order to achieve clean and dirty separation, the barrel body has a clean water cavity and a dirty water cavity that are independent and blocked from each other. The bottom of the barrel body is provided with two concave cavities, which form a dirty water cavity. A water tank is detachably installed in the barrel body. A water pump is directly provided in the water tank. The inner cavity of the water pump constitutes the clean water cavity. The water inlet channel is provided on the outer shell of the water pump and communicates with the inner cavity of the water tank. A switch structure capable of closing the water inlet channel is provided on the water inlet channel. The water tank has a water outlet channel and a water injection port. A first one-way valve that is normally closed is provided in the water outlet channel. A second one-way valve that is normally closed is provided in the water inlet channel. When the water tank is installed on the barrel body, the first one-way valve and the second one-way valve push each other. The first one-way valve opens the water outlet channel of the water tank, and the second one-way valve opens the water inlet channel of the clean water cavity. The water outlet channel of the water tank and the water inlet channel of the clean water cavity are connected and communicated. After the water tank is installed, the water outlet channel of the water tank is automatically connected with the water inlet channel of the clean water chamber, and the clean water chamber is replenished with water pre-stored in the water tank. When the water tank is removed, the water outlet channel of the water tank and the water inlet channel of the clean water chamber are automatically closed. The water outlet channel of the water tank is closed to add water to the water tank, and the water inlet channel of the clean water chamber is closed to prevent dirty water from entering the clean water chamber, and also to prevent excess water from flowing out of the clean water chamber. The design is reasonable and easy to use.

[0003] Although it can achieve clean and dirty water separation, it requires an additional water tank. An auxiliary one-way valve structure is directly provided between the water tank and the clean water chamber. The structure is complicated and the joint is prone to water leakage. In addition, the water tank needs to be filled with water before each operation and then installed in the barrel body. The operation is complicated and the water tank is heavy to carry.

[0004] In addition, the preferred supporting structure involved in the patent includes a transmission shaft and a rotating bracket. The transmission shaft is directly or indirectly driven to rotate by the mop rod of the flat mop. The rotating bracket is connected to the mop plate. The rotating bracket is sleeved on the transmission shaft and can rotate around its own axis relative to the transmission shaft. The rotation of the rotating bracket can drive the mop plate to rotate together. The rotating bracket is connected to the transmission shaft through a reduction mechanism, so that the rotation of the transmission shaft drives the rotating bracket to decelerate through the reduction mechanism. An acceleration gear mechanism is provided between the bottom of the transmission shaft and the input shaft of the water pump, which can drive the water pump to work faster. However, the overall optimal embodiment of the patent is relatively complex and the cost is relatively high. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a dirt separation mop cleaning bucket with a simpler and more reasonable structure, low cost, no lifting required, and capable of cleaning and drying in situ, in view of the above-mentioned existing technical status.

[0006] The technical solution adopted by the present invention to solve the above technical problems is: a cleaning bucket for a cleaning and dirt separation mop, comprising a barrel body having a clean water chamber and a dirty water chamber which are independent and blocked from each other, a transmission shaft for connecting a mop head, and a water spraying mechanism for spraying water on the wiped object on the mop head are arranged in the barrel body, and the water spraying mechanism comprises a wheel cover, a pump wheel and a water spraying channel; the characteristic is that: the clean water chamber is inseparable from the barrel body, the clean water chamber is divided into a water replenishing clean water chamber and a quantitative clean water chamber located at the lower part of the water replenishing clean water chamber, the water replenishing clean water chamber and the quantitative clean water chamber are connected through a water replenishing channel, and a control for controlling the water replenishing speed of the quantitative clean water chamber is arranged at the water replenishing channel. The pump wheel is arranged in the quantitative clean water chamber, the wheel cover covers the pump wheel, the inner cavity of the wheel cover is connected with the quantitative clean water chamber and can take in water, the inner cavity of the wheel cover is connected with the water spray channel through the water outlet on the wheel cover, the water spray channel is provided with a water spray hole, the lower end of the transmission shaft is coaxially connected with the pump wheel, and the upper end of the transmission shaft exposes the sewage chamber; when the mop head is connected to the transmission shaft, the rotation of the mop head drives the transmission shaft and the pump wheel to rotate coaxially together, the rotating pump wheel pumps water out through the water outlet and the water spray channel and then sprays the water to the wiping object through the water spray hole, and the control component works so that the water outlet speed of the quantitative clean water chamber is greater than its water replenishment speed.

[0007] As a further improvement, the barrel body has an annular wall extending upward to form a first concave cavity in the barrel body, and the bottom surface of the first concave cavity has a second concave cavity further recessed downward, and the mouth end cover of the second concave cavity is provided with a second cover plate so that the second concave cavity forms the quantitative clean water cavity, and the water replenishment channel is provided on the second cover plate; the mouth end cover of the first concave cavity is provided with a first cover plate so that the first concave cavity between the first cover plate and the second cover plate forms the water replenishment clean water cavity. This structure quickly forms a sewage cavity, a water replenishment clean water cavity and a quantitative clean water cavity in the barrel body through the annular wall and two cover plates formed in the barrel body at one time, without the need to set up an additional water tank, thereby reducing costs. When adding water, you only need to open the first cover plate, which is very convenient to operate. The setting of the annular wall allows the sewage cavity to be arranged around the clean water cavity, increasing the sewage storage capacity.

[0008] As a further improvement, the bottom surface of the second cavity has a third cavity further concave downward, and the pump wheel is arranged in the third cavity. The pump wheel on this structure is located below the quantitative clean water cavity, which can ensure that the clean water in the quantitative clean water cavity is pumped out as much as possible.

[0009] As a further improvement, the top surface of the second cover plate has a second boss portion extending upward, and the transmission shaft vertically penetrates the second boss portion. The second boss portion extends upward, and the transmission shaft vertically penetrates the second boss portion. The gap between the transmission shaft and the second boss portion is located at the top of the water replenishment and water cleaning chamber. In this way, even if there is no additional sealing structure between the transmission shaft and the second boss portion, it is ensured that the water in the water replenishment and water cleaning chamber will not flow into the connection between the transmission shaft and the second cover plate. The second boss portion is also convenient for hand gripping to remove the second cover plate from the mop bucket.

[0010] As a further improvement, the top surface of the first cover plate has a first boss portion extending upward, and the upper end of the transmission shaft passes through the first boss portion. The first boss portion is higher than the top surface of the first cover plate, plays a water blocking role, and effectively prevents dirty water on the top surface of the first cover plate from flowing into the water replenishment and clean water cavity from the joint between the transmission shaft and the first cover plate.

[0011] As a further improvement, the second boss portion is flat, the upper end of the second boss portion is inserted into the first boss portion, and a snap-fit ​​structure is provided between the outer wall of the second boss portion and the inner wall of the first boss portion. The upper end of the second boss portion is inserted into the first boss portion, and the second boss portion is flat, so that a rotation-limiting structure is formed between the first cover plate and the second cover plate, preventing the first cover plate from rotating, and the cleaning bucket works more stably.

[0012] As a preference, the control member is a switch structure that determines whether the water replenishment clean water chamber is connected to the quantitative clean water chamber. The trigger end of the switch structure passes through the top surface of the second boss portion and the first boss portion in turn. When the mop head is connected to the transmission shaft, the switch structure is triggered by the mop head to close the water replenishment channel, and the water replenishment clean water chamber cannot or reduces the water replenishment to the quantitative clean water chamber, ensuring that the amount of water sprayed to the wipe is gradually reduced. When the mop head is separated from the transmission shaft, the switch structure is reset to open the water replenishment channel. The amount of water sprayed to the wipe by the water spray hole in a unit time is controlled by the setting of the switch structure. During operation, because the water replenishment channel for replenishing water in the given amount of clean water chamber is blocked by the switch structure, water cannot enter the quantitative clean water chamber. When the water in the quantitative clean water chamber becomes less and less, the amount of water sprayed decreases accordingly. If the water in the quantitative clean water chamber is pumped out, the water spray hole no longer sprays water to the wipe, and the wipe is dried by the high-speed rotation of the mop head. Of course, there are many ways to implement the control member, and it can also be a blocking structure that reduces the water inlet speed. For example, the control member may also be a filter component provided at the water inlet end of the water spray mechanism, or a cover with fine holes provided at the water inlet end of the water spray mechanism.

[0013] Specifically, the switch structure includes a switch component that is inserted into the second boss portion and can slide up and down, and an elastic body is provided in the quantitative clean water chamber to keep the switch component in an upward trend; when the mop head is connected to the transmission shaft, the switch component is pressed down by the mop head and moves downward so that the switch component blocks the water supply channel; when the mop head is detached from the transmission shaft, the switch component moves upward under the action of the elastic body so that the switch component opens the water supply channel.

[0014] As a further improvement, the top of the switch component is provided with a contact component that forms rolling friction with the wiping object. The rolling friction can ensure that the mop head rotates more easily. The contact component can be a roller, a steel ball or a cylindrical roller.

[0015] As a preferred structure of the water spray channel, it includes an axial flow channel and a radial flow channel. The axial flow channel is arranged on the second cover plate, and the radial flow channel is arranged on the first cover plate. The lower end of the axial flow channel is plugged and connected with the water outlet on the wheel cover, and the upper end of the axial flow channel is connected with the radial flow channel. The water spray hole is arranged on the radial flow channel. The water spray channel is arranged on the first cover plate and the second cover plate, which is convenient for manufacturing and assembly. The axial flow channel can be directly formed on the second cover plate, or it can be a pipe fitting plugged into the second cover plate.

[0016] As an improvement, the second cover plate and the wheel cover are detachably connected together through a buckle structure. In this way, the wheel cover and the second cover plate can be pre-connected together to form a module, ensuring that the water outlet on the wheel cover is aligned with the lower end of the axial flow channel and connected, and then installed together into the barrel body, which is more convenient to assemble.

[0017] As a further improvement, the radial flow channel extends outwardly to form an annular wall, and an indicating water flow channel is provided at the radial flow channel outside the annular wall to guide part of the water in the radial flow channel to the sewage chamber. The user can directly observe whether water flows out of the indicating water flow channel. If water flows out, it indicates that it is in the water spray cleaning stage, and if no water flows out, it indicates that it is in the spin drying stage, so that the cleaning time of the mop can be accurately controlled.

[0018] Further improvement, the first cover plate is provided with a cleaning component, and the cleaning component is used to clean the wiping material at the bottom of the mop head rotating in the barrel. The cleaning component can be a brush holder containing bristles, and the cleaning operation is achieved by scraping the bristles with the rotating wiping material. In this way, the dirt adhering to the wiping material can be scraped off better, and the cleaning effect is better. Of course, the cleaning component can also be a scraping bar or a squeezing roller, and the cleaning operation is achieved by squeezing the scraping bar or the squeezing roller with the rotating wiping material. Because the wiping material on the bottom surface of the mop head is uneven, or the thickness of the wiping material is different, in order to avoid that the part of the wiping material cannot be brushed by the bristles, further improvement, the lower part of the above-mentioned bristle holder is swingably arranged on the first cover plate, and the bristle holder is kept in an upward swinging trend by the elastic structure to ensure that the bristles are in full contact with the wiping material; or, the bristle holder is floated in the shell of the water spraying mechanism, and the bristle holder is kept in an upward moving trend by the elastic structure to ensure that the bristles are in full contact with the wiping material. In this way, the bristles can swing in a targeted manner to ensure full contact with the wiped object, thereby improving the cleaning effect of the bristles.

[0019] As a further improvement, a sealing ring is provided between the second cover plate and the second concave cavity, and the second cover plate is constrained in the second concave cavity by a rotary clamp structure. The second cover plate fixed in the second concave cavity by a rotary clamp can compress the sealing ring, and the setting of the sealing ring can better separate the quantitative clean water chamber and the replenishing clean water chamber, so that the quantitative clean water chamber and the replenishing clean water chamber can only be connected through the replenishing water channel.

[0020] Preferably, the top surface of the first cover plate is tilted downward from the center to the surrounding directions, so that the dirty water flowing to the top surface of the first cover plate can be quickly discharged to the sewage chamber, and the sewage can be better prevented from entering the water replenishment and clean water chamber.

[0021] As a further improvement, the periphery of the first cover plate has a rotation-limiting dowel extending downward, and the outer periphery of the annular wall is provided with a rotation-limiting slot for the rotation-limiting dowel to be inserted into. This structure has rotation-limiting and fool-proofing functions, and can clearly indicate to customers whether the first cover plate is installed in place during use. If the fool-proof dowel is in a position misaligned with the fool-proofing slot, it indicates that the first cover plate is not installed in place. If the fool-proof dowel is in a position inserted into the fool-proofing slot, it indicates that the first cover plate is installed in place and the water spray channel is in a position that is connected to the inner cavity of the wheel cover.

[0022] As an improvement, the transmission shaft is composed of a joint and a pump wheel shaft provided on the pump wheel and extending upward. A fixed shaft is fixed to the bottom of the quantitative clean water chamber. The pump wheel shaft is sleeved on the fixed shaft through a bearing or a sleeve. The joint is connected to the top of the pump wheel shaft, and the joint is used for transmission connection with the mop head. The connection is a hard connection, which can be a threaded connection or a welded connection, or the transmission shaft and the impeller shaft can be an integrally formed part. This structure can make the transmission shaft rotate easily, and the setting of the fixed shaft provides a suitable installation position for the transmission shaft.

[0023] In order to make the transmission shaft rotate more easily, a steel ball is provided on the top of the fixed shaft to support the top surface of the joint.

[0024] Compared with the prior art, the advantages of the present invention are:

[0025] 1. The clean water chamber is inseparable from the barrel body. The clean water chamber is divided into a water replenishing clean water chamber located at the upper part and a quantitative clean water chamber located at the lower part. No additional water tank is required. The water replenishing clean water chamber is located above the quantitative clean water chamber, which is conducive to replenishing water to the quantitative clean water chamber.

[0026] 2. The replenishing and cleaning water chamber is connected to the quantitative clean water chamber through a replenishing water channel, and a control component for controlling the water inlet speed of the quantitative clean water chamber is provided at the replenishing water channel. When the mop head is connected to the transmission shaft, the control component works so that the water outlet speed of the quantitative clean water chamber is greater than its water inlet speed. At the beginning, the water spraying amount is large, and the amount of water obtained on the wipes is greater than the amount of water obtained by spinning. This process is a cleaning process. The water spraying amount gradually decreases, and the amount of water obtained by spinning is greater than the amount of water obtained on the wipes. This process is a spinning process. Since cleaning and spinning are completed at the same position, there is no need to set a cleaning position and a spinning position in the barrel body respectively, so that the volume of the entire barrel body is greatly reduced compared with the traditional mop head.

[0027] 3. The rotation of the mop head drives the transmission shaft and the pump wheel to rotate coaxially. There is no need to set an additional rotating bracket on the transmission shaft to drive the mop head to rotate, and there is no need to set a reduction mechanism. At the same time, the water pressure component is directly driven by the rotation of the transmission shaft, and there is no need to set an acceleration mechanism between the water pressure component and the transmission shaft. Therefore, the structure of this cleaning tool is greatly simplified and the cost is greatly reduced. Through continuous experiments, this simplified version of the structure can also achieve good water spraying and scraping effects. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] The clean water chamber is inseparable from the barrel body 1, and the clean water chamber is divided into a water replenishment clean water chamber 1b and a quantitative clean water chamber 1c located at the lower part of the water replenishment clean water chamber 1b. The water replenishment clean water chamber 1b is connected with the quantitative clean water chamber 1c through a water replenishment channel 1d. A control member 2 for controlling the water replenishment speed of the quantitative clean water chamber 1c is provided at the water replenishment channel 1d. The pump wheel 6 is arranged in the quantitative clean water chamber 1c, and the wheel cover 5 covers the pump wheel 6. The inner cavity of the wheel cover 5 is connected with the quantitative clean water chamber 1c and can take in water. The inner cavity of the wheel cover 5 is connected with the water spray channel 7 through the water outlet 51 on the wheel cover 5. The water spray channel 7 A water spray hole 71 is provided on it, the lower end of the transmission shaft 3 is coaxially connected to the pump wheel 6, and the upper end of the transmission shaft 3 reveals the sewage chamber 1a; when the mop head 4 is connected to the transmission shaft 3, the connection is generally sleeved on the transmission shaft and driven by the rib groove plug-in method, the rotation of the mop head 4 drives the transmission shaft 3 and the pump wheel 6 to rotate coaxially together, the rotating pump wheel 6 pumps water out through the water outlet 51 and the water spray channel 7, and then sprays it to the wipe 41 through the water spray hole 71, and the control part 2 works so that the water outlet speed of the quantitative clean water chamber 1c is greater than its water replenishment speed.

[0041] The barrel body 1 has an upwardly extending annular wall 14 to form a first concave cavity 11 in the barrel body, and the bottom surface of the first concave cavity 11 has a second concave cavity 12 which is further recessed downward. The mouth end cover of the second concave cavity 12 is provided with a second cover plate 9 so that the second concave cavity 12 forms the quantitative clean water cavity 1c, and the water replenishment channel 1d is provided on the second cover plate 9. At the same time, the second cover plate 9 and the wheel cover 5 are detachably connected together through a snap-on structure; the mouth end cover of the first concave cavity 11 is provided with a first cover plate 8 so that the first concave cavity 11 between the first cover plate 8 and the second cover plate 9 forms the water replenishment clean water cavity 1b.

[0042] The bottom surface of the second cavity 12 has a third cavity 13 which is further recessed downward, and the pump wheel 6 is disposed in the third cavity 13.

[0043] The top surface of the second cover plate 9 has a second boss portion 91 extending upward, and the transmission shaft 3 vertically penetrates the second boss portion 91. The top surface of the first cover plate 8 has a first boss portion 81 extending upward, and the upper end of the transmission shaft 3 penetrates the first boss portion 81. The second boss portion 91 is flat, and the upper end of the second boss portion 91 is inserted into the first boss portion 81, and a snap-fit ​​structure is provided between the outer wall of the second boss portion 91 and the inner wall of the first boss portion 81.

[0044] The control member 2 in this embodiment is a switch structure that determines whether the water replenishment and clean water chamber 1b is connected to the quantitative clean water chamber 1c. The trigger end of the switch structure passes through the top surfaces of the second boss portion 91 and the first boss portion 81 in turn. When the mop head 3 is connected to the transmission shaft 3, the switch structure is triggered by the mop head 4 to close the water replenishment channel 1d, and the water replenishment and clean water chamber 1b cannot or reduces the water replenishment to the quantitative clean water chamber 1c, ensuring that the amount of water sprayed onto the wipe 41 gradually decreases. When the mop head 4 is disconnected from the transmission shaft 3, the switch structure is reset to open the water replenishment channel 1d.

[0045] The switch structure includes a switch component 21 that is inserted into the second boss portion 91 and can slide up and down. An elastic body 22 is provided in the quantitative clean water chamber 1c to keep the switch component 21 moving upward. When the mop head 4 is connected to the transmission shaft 3, the switch component 21 is pressed down by the mop head 4 and moves downward so that the lower end of the switch component 21 blocks the water supply channel 1d. When the mop head 4 is separated from the transmission shaft 3, the switch component 21 moves upward under the action of the elastic body 22 so that the lower end of the switch component 21 opens the water supply channel 1d. The top of the switch component 21 is provided with a contact component 23 that forms rolling friction with the wipe 41.

[0046] The water spray channel 7 includes an axial flow channel 7a and a radial flow channel 7b. The axial flow channel 7a is provided on the second cover plate 9. A sealing ring 15 is provided between the second cover plate 9 and the second concave cavity 12. The second cover plate 9 is constrained in the second concave cavity 12 by a rotating clamp structure. The radial flow channel 7b is provided on the first cover plate 8. The lower end of the axial flow channel 7a is plug-connected with the water outlet 51 on the wheel cover 5. The upper end of the axial flow channel 7a is plug-connected with the radial flow channel 7b. The water spray hole 71 is provided on the radial flow channel 7b. The radial flow channel 7b extends outwardly to form an annular wall 14. The radial flow channel 7b located outside the annular wall 14 is provided with an indicating water flow channel 7c for partially guiding the water in the radial flow channel 7b to the sewage chamber 1a.

[0047] A cleaning member 10 is provided on the first cover plate 8, and the cleaning member 10 is used to clean the wiping material 41 at the bottom of the mop head 4 rotating in the barrel body 1. The cleaning member 10 is arranged radially with the axis of the transmission shaft 3 as the center, and the cleaning member 10 covers the wiping material 41 in the radial direction along one side of the center of the mop head 4 from inside to outside.

[0048] The working principle and process of this cleaning tool are as follows:

[0049] Cleaning and drying process: open the first cover plate 8, and fill the water into the water replenishment and clean water chamber 1b to a suitable height. At this time, because the mop head 4 is not connected to the transmission shaft 3, the lower end of the switch component 21 opens the water replenishment channel 1d, and the clean water in the water replenishment and clean water chamber 1b is filled with the quantitative clean water chamber 1c through the water replenishment channel 1d, and the first cover plate 8 is covered. Then the mop head 4 is connected to the transmission shaft 3, and the switch component 21 is pressed down by the mop head 4 and moves downward, so that the lower end of the switch component 21 blocks the water replenishment channel 1d, and no or a small amount of water is replenished in the quantitative clean water chamber 1c. The mop rod is operated to drive the transmission shaft 3 and the mop head 4 to rotate synchronously and coaxially. The transmission shaft 3 drives the pump wheel 6 to rotate. The rotating pump wheel 6 pumps clean water through the water outlet 51 and the water spray channel 7 and then sprays it onto the wipe 41 through the water spray hole 71. During the whole process, the quantitative clean water chamber 1c is no longer or only replenished with water in small amounts. As the mop head 4 rotates, the water in the quantitative clean water chamber 1c becomes less and less, so that the water spraying amount is large at the beginning, and the amount of water obtained on the wipe 41 is greater than the amount of water obtained on the wipe 41. This process is a cleaning process. The water spraying amount gradually decreases. After the water in the quantitative clean water chamber 1c is used up or basically used up, the pump wheel 6 idles, and the water spray hole 71 no longer sprays water or sprays very little water. Therefore, the wipe 41 is only spun dry, or the amount of water spun dry by the wipe 41 is greater than the amount of water obtained on the wipe 41. This process is a drying process.

[0050] Since cleaning and drying are completed at the same position, there is no need to set up a cleaning position and a drying position separately in the barrel body, so that the volume of the entire barrel body is greatly reduced compared with the traditional mop head.

[0051] After the work is completed, the mop head is removed from the transmission shaft 3, and the switch component 21 moves up and resets under the action of the elastic body 22. The lower end of the switch component 21 opens the water supply channel 1d, and the clean water in the water supply chamber 1b replenishes the clean water chamber 1c again through the water supply channel 1d, waiting for the next operation.

[0052] If the pump wheel 6 needs to be cleaned, the second cover plate 9 only needs to be opened to take out the pump wheel 6 for cleaning.

[0053] It should be noted that in the description of this embodiment, the terms "front, rear", "left, right", "up, down", etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.
