Description

Technical Field

[0001] The present invention relates to a cleaning tool, and more particularly to a cleaning bucket for cleaning a mop at the bottom of a floor mopping machine. Background Art

[0002] A floor mopping machine is a common automated cleaning tool in daily life. A floor mopping machine usually consists of a base and a joystick rotatably connected above the base. At least one (usually two) turntables rotatably connected by a motor are arranged in the base, and a turntable-type mop is pasted under the turntable. When in use, the high-speed rotation of the turntable is driven to drive the mop to clean the floor at a high speed. For example, "An Electric Floor Mopping Machine" disclosed in the publication number CN110393485A, "A Floor Mopping Machine" related to the announcement number CN209252719U, and "A Floor Mopping Machine" disclosed in CN205493728U, etc.

[0003] During the use of a floor mopping machine, in order to ensure its cleaning effect and accelerate the cleaning rate, the mop pasted under the turntable is often cleaned and sorted frequently. Since the whole floor mopping machine cannot be placed in the clear water of the water bucket to fully soak and rinse the mop, the method of removing the mop from the turntable one by one for manual scrubbing or putting it into a washing machine for cleaning can only be adopted. However, the manual scrubbing method is time-consuming and laborious. Some stubborn dirt such as hair, dust, and food residue particles adhered to the mop are firmly attached, and it is necessary to constantly pull them off by hand, which brings hygienic problems. Moreover, continuous scrubbing will also damage the hand skin, and it is difficult to achieve the desired effect of cleaning the mop thoroughly; putting it into the washing machine for cleaning will cause relatively serious pollution to the washing machine; in addition, although there are some water buckets on the market that can clean the mop of the floor mopping machine, after the mop is cleaned, since the water in the mop cannot be effectively squeezed out, the mop is too wet. When the floor mopping machine is further used, the water droplets on the mop will drip, resulting in a large amount of water droplets remaining on the ground, which not only seriously affects the user experience, but also poses a hidden danger of slippery ground causing people to fall.

[0004] There is a patent application for invention "An Inner and Outer Bucket Type Cleaning Device for a Floor Mopping Machine Rag" with the application number CN202010119177.9 (publication number CN111166254A), which discloses such a cleaning device. The floor mopping machine includes a floor mopping machine body, and the floor mopping machine body includes a joystick, a drive base arranged below the joystick in the height direction, and at least one turntable installed at the bottom position. The drive base is in transmission connection with the turntable, and a rag is arranged below the turntable. It is characterized in that: the inner and outer bucket type cleaning device includes a water storage outer bucket and a cleaning inner bucket. An outer bucket body cavity with an opening facing upward is formed in the water storage outer bucket. A waterproof wall is arranged in the outer bucket body cavity along its height direction. The waterproof wall divides the outer bucket body cavity into an independent water storage area and a water-free area. The cleaning inner bucket is arranged at the upper position in the height direction in the outer bucket body cavity, and the cleaning inner bucket is horizontally mounted on the waterproof wall and can be turned downward by a certain angle toward the water storage area side.

[0005] The foregoing cleaning device can efficiently soak and clean the rag without tearing the rag from the turntable. However, it realizes the switching between cleaning and dehydration by the flipping of the inner bucket. The connection structure between the inner bucket and the outer bucket is complex and the operation is inconvenient. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a floor mopping machine cleaning bucket with a simpler and more reasonable structure and strong applicability in view of the above-mentioned current situation of the prior art. The cleaning bucket can clean and spin-dry the rag on the floor mopping machine in place without tearing the rag from the turntable.

[0007] The technical solution adopted by the present invention to solve the above technical problems is as follows: a cleaning bucket for a floor scrubber, which is used in conjunction with the floor scrubber. The floor scrubber includes at least one turntable installed at the bottom of the machine base and driven by a motor to rotate. A wiping object is provided on the bottom surface of the turntable. It includes a barrel body. A drive shaft corresponding to the turntable in number is provided in the barrel body. The drive shaft and the turntable are connected by a detachable connection structure. It is characterized in that: each group of drive shafts is correspondingly connected to a group of water spraying mechanisms provided in the barrel body. Each group of the water spraying mechanisms includes a pump housing and an impeller. The pump housing covers the impeller. The inner cavity of the pump housing is communicated with the inner cavity of the barrel body to allow water to enter. The impeller is a two-way water pumping impeller. The pump housing is provided with a first water outlet and a second water outlet. The first water outlet is connected to a first water spraying channel, and the second water outlet is connected to a second water spraying channel. The first water spraying channel is provided with first water spraying holes, and the second water spraying channel is provided with second water spraying holes. In the state where the turntable is connected to the drive shaft, the clockwise rotation of the turntable drives the drive shaft and the impeller to rotate clockwise together. The rotating impeller pumps water out and sprays it onto the wiping object through the first water outlet, the first water spraying channel and then the first water spraying holes. The counterclockwise rotation of the turntable drives the drive shaft and the impeller to rotate counterclockwise together. The rotating impeller pumps water out and sprays it onto the wiping object through the second water outlet, the second water spraying channel and then the second water spraying holes.

[0008] The effect of the drive shaft and the impeller rotating coaxially and at the same speed is the best. Of course, they can also only rotate at the same speed and do not necessarily need to be coaxially arranged. As long as the drive shaft, the mopping head and the impeller of the water spraying mechanism are involved, for example, the same speed rotation can be driven by a same speed transmission mechanism between the drive shaft and the impeller, but the drive shaft and the impeller are not coaxially arranged.

[0009] As the specific structure of the two-way water pumping impeller, multiple groups of vanes are provided on the surface of the above impeller at intervals along the circumference. Each group of vanes includes a first vane and a second vane that are both arc-shaped. The concave surfaces of the first vane and the second vane in each group of vanes are arranged opposite to each other, and the inclination angles of the first vanes in each group of vanes are the same, and the inclination angles of the second vanes in each group of vanes are the same. When the impeller rotates clockwise, the first vane plays a role in pumping water. When the impeller rotates counterclockwise, the second vane plays a role in pumping water.

[0010] To ensure the smooth rotation of the impeller, an impeller shaft extending upward is provided at the central position of the above impeller. A fixed shaft is fixed at the bottom in the barrel body. The impeller shaft on the impeller is sleeved on the fixed shaft through a bearing or a bushing. The drive shaft is connected to the top of the impeller shaft. The connection is a rigid connection, which can be a threaded connection, a welded connection, or the drive shaft and the impeller shaft are integrally formed parts.

[0011] Preferably, there are two turntables, two transmission shafts, and two sets of water spraying mechanisms. The two pump casings are connected by a connecting part, and a cover plate is provided on the connecting part. The first water spraying channels and the second water spraying channels in each water spraying mechanism are arranged on the connecting part, and the first water spraying holes and the second water spraying holes in each water spraying mechanism are arranged on the cover plate. The connecting component connects the two pump casings, so that the two pump casings can be formed with the connecting component as an integral part, which is beneficial to manufacturing and assembly.

[0012] Further improvement: The above-mentioned first water spraying channel and the second water spraying channel are arranged on the connecting part and are separated by a transverse partition. A cover plate covering the first water spraying channel and the second water spraying channel is provided on the connecting part. A longitudinal partition extending downward to the middle parts of the first water spraying channel and the second water spraying channel is provided on the bottom surface of the cover plate to divide them into left and right parts to form the first water spraying channel and the second water spraying channel corresponding to the water spraying mechanism. The first water spraying holes and the second water spraying holes are arranged on the cover plate. The arrangement of the connecting part provides a reasonable position for the water spraying channels and centrally arranges the two water spraying channels in the two water spraying mechanisms, which is beneficial to the layout.

[0013] Further improvement: The interior of the above-mentioned barrel is divided into two independent water chambers, namely a sewage chamber located in the upper part and a clean water chamber located in the lower part. The water spraying mechanism is arranged in the clean water chamber. The inner cavity of the pump casing is communicated with the clean water chamber to allow water to enter. The transmission shaft extends into the sewage chamber for connecting with the turntable. This structure realizes the separation of clean water and sewage, ensuring that only clean water is used to clean the wiping object during cleaning, which can clean the mop more thoroughly and improve the cleaning effect.

[0014] Preferably, the above-mentioned sewage chamber and the clean water chamber are communicated through a water replenishing port. The control member is a switch structure capable of opening and closing the water replenishing port. In the state where the switch structure closes the water replenishing port, the sewage chamber cannot or reduces the replenishment of water to the clean water chamber, ensuring that the amount of water sprayed by the water spraying mechanism onto the wiping object gradually decreases. Since the water inlet speed is less than the water outlet speed, when the water in the inner cavity of the water spraying mechanism becomes less and less, the amount of water sprayed out decreases accordingly. If the water in the inner cavity is pumped out, the water spraying end of the water spraying mechanism will no longer spray water onto the wiping object, and the wiping object is dried by the high-speed rotation of the mop head, realizing in-situ cleaning and drying operations. There are various implementation methods for the control member. It can be a switch structure that completely closes the water inlet volume at the water inlet end, or a blocking structure that reduces the water inlet speed. For example, the control member can also be a filtering component arranged at the water inlet end of the water spraying mechanism, or a lid with fine holes arranged at the water inlet end of the water spraying mechanism.

[0015] Preferably, the above-mentioned switch structure is triggered by a turntable resting on the transmission shaft to close the water replenishing port. A filtering structure is provided at the water replenishing port. When the turntable is disengaged from the transmission shaft, the switch structure automatically opens the water replenishing port. During operation, the turntable must be connected to the rotating shaft, so the method of using the turntable to trigger the switch is the most reasonable, without the need to additionally set up a triggering component. Of course, other triggering methods can also be adopted, such as directly manually closing. The setting of the filtering structure can filter the water in the sewage chamber and reuse it, achieving the effect of water conservation.

[0016] Preferably, the above-mentioned switch structure includes a switch component that can slide up and down and is inserted through the water replenishing port, and the switch component is arranged beside the transmission shaft. The switch component has an upward movement tendency under the action of an elastic body. When the turntable is connected to the transmission shaft, the switch component is pressed down by the turntable and moves downward so that the lower end of the switch component blocks the water replenishing port. When the turntable is disengaged from the transmission shaft, the switch component moves upward under the action of the elastic body so that the lower end of the switch component opens the water replenishing port. By setting the switch component, the amount of water sprayed onto the wiping object by the spraying end of the spraying mechanism per unit time can be controlled. During operation, since the water replenishing port is blocked by the switch component, water cannot enter the clean water chamber, and the amount of water replenished into the inner cavity of the water pump through the clean water chamber becomes less and less, and the amount of water sprayed out decreases accordingly. If the water in the clean water chamber is pumped out (the water in the pump chamber is lower than the impeller), the spraying end of the spraying mechanism will no longer spray water onto the wiping object, and the wiping object can be dried or scraped dry by rotating the turntable.

[0017] As an improvement, an inner barrel body is placed in the above-mentioned barrel body. The inner cavity of the inner barrel body forms the sewage chamber, and the inner cavity of the barrel body below the bottom surface of the inner barrel body forms the clean water chamber. Using the inner barrel body to form the clean water chamber and the sewage chamber is the simplest method, and it is convenient for assembly and product molding.

[0018] For further improvement, a cleaning component is also provided in the above-mentioned barrel body. The cleaning component is used to clean the wiping object at the bottom of the turntable rotating in the barrel body. The cleaning component can be bristles, which can better scrape off the dirt sticking to the wiping object and has a better cleaning effect. Of course, the cleaning component can also be a scraping strip or an extrusion roller, and the cleaning operation is realized by squeezing the rotating wiping object with the scraping strip or the extrusion roller. A water scraping strip is also provided in the above-mentioned barrel body. The water scraping strip is used to scrape water from the wiping object at the bottom of the turntable rotating in the barrel body. The water scraping strip can better squeeze out the water on the wiping object, without the need for rapid drying, and has a good dehydration effect.

[0019] Compared with the prior art, the advantages of the present invention are as follows: when the turntable is connected to the transmission shaft, the rotation of the turntable drives the transmission shaft and the impeller to rotate together. The rotating impeller pumps water out and sprays it onto the wiping object through the water outlet, the water spraying channel and then the water spraying holes. It cleans while spraying water and rotating, without the need to set up a complex swinging structure to realize whether the wiping object on the turntable is immersed in water or not, and the structure is simpler and more reasonable compared with the cleaning bucket of the existing floor scrubber. Importantly, the impeller is a two-way water pumping impeller, and there are two water outlets and water spraying channels. Whether the turntable rotates clockwise or counterclockwise, it can pump water out of the corresponding water spraying holes and spray it onto the wiping object, which can adapt to floor scrubbers with different rotation directions and has good adaptability.

[0030] The present invention will be further described in detail below with reference to the embodiments in the drawings.

[0031] As Figures 1 to 10 shown, it is the first embodiment of the present invention.

[0032] A mopping machine cleaning bucket is used in conjunction with a mopping machine. The mopping machine includes two turntables 2 installed at the bottom of the machine base and driven to rotate by a motor. The turntables 2 rotate synchronously and in opposite directions. A wiping material 4 is provided on the bottom surface of the turntable 2, and the wiping material 4 can be a rag or the like.

[0033] Specifically, the cleaning bucket includes a bucket body 1. Two transmission shafts 3 corresponding to the turntables 2 are provided inside the bucket body 1. The transmission shafts 3 and the turntables 2 are connected by a detachable connection structure. Specifically, a connection hole 21 with a non-circular cross-section (such as a polygon, an ellipse, a semi-circle, etc.) is provided on the bottom surface of the turntable 2, and the outer shape of the cross-section of the transmission shaft 3 matches the connection hole 21.

[0034] The two transmission shafts 3 are correspondingly connected to a set of water spraying mechanisms provided inside the bucket body 1. There are two sets of water spraying mechanisms. Each set of water spraying mechanisms includes a pump housing 5 and an impeller 6. The pump housing 5 covers the impeller 6. The inner cavity of the pump housing 5 is communicated with the inner cavity of the bucket body 1 to allow water to enter. The impeller 6 is a two-way water pumping impeller. A first water outlet 5a and a second water outlet 5b are provided on the pump housing 5. The introduction directions of the first water outlet 5a and the second water outlet 5b are opposite. The first water outlet 5a is connected to a first water spraying channel 7a, and the second water outlet 5b is connected to a second water spraying channel 7b. A first water spraying hole 71a is provided on the first water spraying channel 7a, and a second water spraying hole 71b is provided on the second water spraying channel 7b. In the state where the turntable 2 is connected to the transmission shaft 3, the clockwise rotation of the turntable 2 drives the transmission shaft 3 and the impeller 6 to rotate clockwise together. The rotating impeller 6 pumps water out and sprays it onto the wiping material 4 through the first water outlet 5a, the first water spraying channel 7a, and then through the first water spraying hole 71a. The counterclockwise rotation of the turntable 2 drives the transmission shaft 3 and the impeller 6 to rotate counterclockwise together. The rotating impeller 6 pumps water out and sprays it onto the wiping material 4 through the second water outlet 5b, the second water spraying channel 7b, and then through the second water spraying hole 71b.

[0035] A plurality of groups of blade pieces are provided on the surface of the impeller 6 at intervals along the circumference. Each group of blade pieces includes a first blade piece 6a and a second blade piece 6b that are both arc-shaped. The concave surfaces of the first blade piece 6a and the second blade piece 6b in each group of blade pieces are arranged opposite to each other, and the inclination angles of the first blade piece 6a in each group of blade pieces are the same, and the inclination angles of the second blade piece 6b in each group of blade pieces are the same. An impeller shaft 61 extending upward is provided at the center position of the impeller 6. A fixed shaft 13 is fixed at the bottom inside the bucket body 1. The impeller shaft 61 on the impeller is sleeved on the fixed shaft 13 through a bearing or a bushing. The transmission shaft 3 is connected to the top of the impeller shaft 61.

[0036] The two pump casings 5 are connected by a connecting portion 52, and a cover plate 53 is provided on the connecting portion 52. The first water spraying channels 7a and the second water spraying channels 7b in each water spraying mechanism are both arranged on the connecting portion 52, and the first water spraying holes 71a and the second water spraying holes 71b in each water spraying mechanism are both arranged on the cover plate 53. The first water spraying channel 7a and the second water spraying channel 7b are arranged on the connecting portion 52 and are separated from each other by a transverse partition 51a. A cover plate 53 covering the first water spraying channel 7a and the second water spraying channel 7b is provided on the connecting portion 52. A longitudinal partition 51b extending downward to the middle parts of the first water spraying channel 7a and the second water spraying channel 7b is provided on the bottom surface of the cover plate 53 to divide it into left and right parts to form the first water spraying channel 7a and the second water spraying channel 7b corresponding to the water spraying mechanisms. The first water spraying holes 71a and the second water spraying holes 71b are arranged on the cover plate 53.

[0037] The interior of the barrel body 1 is divided into two independent water chambers, namely a sewage chamber 1a located in the upper part and a clean water chamber 1b located in the lower part. An inner barrel body 11 is placed inside the barrel body 1, and the inner cavity of the inner barrel body 11 forms the sewage chamber 1a, and the inner cavity of the barrel body 1 below the bottom surface of the inner barrel body 11 forms the clean water chamber 1b. The water spraying mechanism is arranged in the clean water chamber 1a. The inner cavity of the pump casing 5 is communicated with the clean water chamber 1a to allow water to enter, and the transmission shaft 3 extends into the sewage chamber 1b to be connected to the turntable 2.

[0038] The water spraying mechanism is controlled by a control member to control the amount of water sprayed onto the wiping object 4 by the water spraying holes of the water spraying mechanism per unit time; the cleaning operation is divided into two time periods, and the amount of water sprayed by the water spraying mechanism onto the wiping object 4 in the first time period is greater than that in the second time period.

[0039] The sewage chamber 1a and the clean water chamber 1b are communicated through a water replenishing port 10. The control member is a switch structure capable of opening and closing the water replenishing port 10. In the state where the switch structure closes the water replenishing port 10, the sewage chamber 1a cannot or reduces the replenishment of water to the clean water chamber 1b, ensuring that the amount of water sprayed by the water spraying mechanism onto the wiping object 4 gradually decreases. The switch structure is triggered by the turntable 2 placed on the transmission shaft to close the water replenishing port 10. A filtering structure 101 is provided at the water replenishing port 10. In the state where the turntable is separated from the transmission shaft, the switch structure automatically opens the water replenishing port 10.

[0040] Specifically, the switch structure includes a switch member 8 that can slide up and down through the water replenishing port 10, and the switch member 8 is arranged beside the transmission shaft 3. The switch member 8 is kept in an upward moving trend by the action of an elastic body 81; in the state where the turntable 2 is connected to the transmission shaft 3, the switch member 8 is pressed down by the turntable 2 and moves downward so that the lower end of the switch member 8 blocks the water replenishing port 10. In the state where the turntable 2 is separated from the transmission shaft 3, the switch member 8 moves upward under the action of the elastic body 81 so that the lower end of the switch member 8 opens the water replenishing port 10.

[0041] A cleaning component 9 is also provided inside the barrel body 1. The cleaning component 9 is fixed to the bottom surface of the inner barrel body 11 and is used to clean the wiping material 4 at the bottom of the turntable 2 rotating inside the barrel body 1. The cleaning component 9 is a brush. The cleaning component 9 is radially arranged with the axis of the transmission shaft 3 as the center of the circle, and the cleaning component 9 covers the wiping material 4 in the radial direction along one side of the center of the turntable 2 from the inside to the outside.

[0042] A wiper strip 12 is also provided inside the barrel body 1. The wiper strip 12 is used to perform a water scraping operation on the wiping material 4 at the bottom of the turntable 2 rotating inside the barrel body 1. The wiper strip 12 is radially arranged with the axis of the transmission shaft 3 as the center of the circle, and the wiper strip 12 covers the wiping material 4 in the radial direction along one side of the center of the turntable 2 from the inside to the outside.

[0043] The working principle and process of this cleaning tool are as follows:

[0044] Cleaning and dehydration process: Fill the barrel body 1 with water. When the turntable 2 is not connected to the transmission shaft 3, the elastic body 81 causes the switch component 8 to move upward to open the water replenishing port 10, and clean water enters the clean water chamber 1b through the water replenishing port 10. It is better to ensure that the clean water chamber 1b is full of water. Then connect the turntable 2 to the transmission shaft 3. The switch component 8 is pressed down by the turntable 2 and moves downward so that the lower end of the switch component 8 blocks the water replenishing port 10, and no more or only a small amount of water is replenished to the clean water chamber 1b. The floor scrubber drives the turntable 2 to rotate. For example, the clockwise rotation of the turntable 2 drives the transmission shaft 3 and the impeller 6 to rotate clockwise together. The rotating impeller 6 pumps the water out and sprays it onto the wiping material 4 through the first water outlet 5a, the first water spraying channel 7a, and then through the first water spraying hole 71a; the counterclockwise rotation of the turntable 2 drives the transmission shaft 3 and the impeller 6 to rotate counterclockwise together. The rotating impeller 6 pumps the water out and sprays it onto the wiping material 4 through the second water outlet 5b, the second water spraying channel 7b, and then through the second water spraying hole 71b; for example, the counterclockwise rotation of the turntable 2 drives the transmission shaft 3 and the impeller 6 to rotate counterclockwise together. The rotating impeller 6 pumps the water out and sprays it onto the wiping material 4 through the second water outlet 5b, the second water spraying channel 7b, and then through the second water spraying hole 71b.

[0045] During the whole process, no more or only a small amount of water is replenished to the inside of the clean water chamber 1b. The water in the clean water chamber 1b becomes less and less, so that the water spraying amount is large at the beginning, and the amount of water obtained on the wiping material is greater than the amount of water squeezed and scraped. This process is the cleaning process. The water spraying amount gradually decreases. When the water in the clean water chamber 1b is used up or basically used up, the impeller 6 rotates idly and no more or only a small amount of water is sprayed. At this time, the amount of water scraped off is greater than the amount of water obtained on the wiping material. This process is the dehydration process. Since both cleaning and dehydration are completed at the same position, there is no need to separately set a cleaning position and a drying position inside the barrel, which greatly reduces the volume of the entire barrel body compared with the cleaning barrel of the existing floor scrubber.

[0046] After the work is completed, take out the mop bucket body 1 of the floor scrubber, remove the turntable 2 from the transmission shaft 3, the switch component 8 moves upward and resets under the action of the elastic body 81, open the water replenishing port 10, and the water in the sewage chamber 1a is filtered by the filtering structure 101 and then replenishes the clean water chamber 1b for the next operation.

[0047] It should be noted that in the description of this embodiment, the orientation or positional relationship indicated by terms such as "front, back", "left, right", "up, down", etc. is based on the orientation or positional relationship shown in the drawings. It is 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 orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention. The terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the internal communication of two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
