Description

Technical Field

[0001] The invention belongs to the technical field of cleaning tools in daily life articles, and in particular relates to an inner and outer barrel cleaning device of a floor cleaning machine rag. Background Art

[0002] The above-mentioned floor scrubber is an automatic cleaning tool commonly used in daily life. The floor scrubber is usually composed of a driving base and a joystick rotatably mounted above the driving base. At least one turntable connected by a motor is arranged in the driving base, and a turntable-type rag is pasted under the turntable. When in use, the high-speed rotation of the turntable is driven to drive the rag to clean the floor at high speed. The floor scrubber is not only suitable for fine cleaning of household floors, supermarket floors, etc., but also can meet the needs of efficient cleaning of large areas such as warehouses and large factories. Therefore, the floor scrubber has the characteristics of being intelligent and convenient, efficient and practical, labor-saving and widely used. There is no lack of technical information related to the floor scrubber in the public Chinese patent documents, such as the "electric floor scrubber" recommended by CN110393485A, the "floor scrubber" involved in CN209252719U, and the "floor scrubber" introduced in CN205493728U.

[0003] During the use of the floor scrubber, in order to ensure its cleaning effect and speed up the cleaning speed, the rag attached under the turntable is often cleaned and tidied frequently. Since the entire floor scrubber cannot be placed in the clean water in the bucket to fully soak and rinse the rag, otherwise the motor and related electronic components of the floor scrubber will be flooded and short-circuited and damaged after power is turned on, the only way is to remove the rags from the turntable one by one and scrub them manually, but the scrubbing method is time-consuming and laborious, and some stubborn dirt such as hair, dust and food residue particles adhere to the rags more firmly, and need to be constantly torn off by hand, which will bring more hygiene problems, and constant scrubbing will also damage the skin of the hands, and it is difficult to achieve the desired effect of cleaning the rags as new; in addition, although there are some buckets on the market that can be used to clean the rags of floor scrubbers, after the rags are cleaned, the water in the rags cannot be effectively squeezed out, causing the rags to be too wet. When the floor scrubber is further used, the water droplets on the rags drip, resulting in a large number of water droplets remaining on the ground, which not only seriously affects the user's experience, but also has the hidden danger of slippery ground causing people to fall.

[0004] In the disclosed Chinese patent documents, there is a lot of relevant technical information about the flat-type mop cleaning and squeezing bucket, a few of which include a "cotton flat-type mop squeezing bucket" given in CN208404441U, a "mop squeezing bucket" mentioned in CN209547927U, and a "multifunctional bucket" disclosed in CN209529062. Although the above technical solutions can effectively solve the problem of the flat-type mop rag being too wet after cleaning, there is a common disadvantage that the mop head of the flat-type mop can only be squeezed dry, but the turntable rag cannot be effectively cleaned and squeezed dry while keeping the mopping machine intact. Another example is the technical solution of the cleaning device provided by "A plate mop and a large bucket type cleaning device" given in the authorization announcement number CN209153472U. Although this solution can effectively solve the problems such as inconvenient cleaning and easy to carry the cleaning bucket, and prevent the splashing of sewage, in addition to the above-mentioned problem that it is not applicable to the mopping machine rag, when cleaning, the mop head needs to be placed in a dehydration chamber with an inclined surface, that is, a large upper space and a small lower space. In the process of placing the mop head downward or lifting it upward, a lot of force is required, and the operation is quite inconvenient; at the same time, when installing the large bucket type cleaning device, the fixing frame needs to be installed on the barrel body with a bearing pad. Therefore, it is necessary to install the bearing pad first, and then install the fixing frame and other components. The components are complicated, the operation procedures are cumbersome, and the production cost is too high.

[0005] In view of the above situation, it is necessary to improve. For this reason, the applicant has made a useful design, and the technical solution to be introduced below is produced under this background. Summary of the invention

[0027] In this embodiment, the aforementioned waterproof wall 12 is arranged in a "]" shape, and the waterproof wall 12 includes a pair of inner barrel support plates 121 arranged horizontally at the front and rear ends of the waterproof wall 12, a pair of water retaining plates 122 arranged longitudinally between the right ends of the two inner barrel support plates 121, and a central partition 123 arranged longitudinally between the two water retaining plates 122. The left end of the aforementioned inner barrel support plate 121 is fixedly installed with the inner side wall of the left side plate of the water storage outer barrel 1, and a downward concave is provided on the upper end surface of the inner barrel support plate 121. There are multiple drain ports 1211. If there is too much water in the water storage area 111, the water can flow into the waterless area 112 from the drain ports 1211 to stabilize the water level in the water storage area 111. A flip foot accommodating groove 1221 is provided on the upper end surface of the aforementioned water baffle 122 and runs through the length direction of the water baffle 122. The width of the aforementioned central partition 123 is smaller than the width of the water baffle 122. A positioning cavity 124 is formed on the side of the aforementioned central partition 123 facing the waterless area 112 and between the two water baffles 122.

[0028] Preferably, a plurality of ribs 125 for supporting the water retaining plate 122 are arranged in the aforementioned waterless area 112 and along its height direction, and handles 14 are arranged at the front and rear ends of the aforementioned water storage outer barrel 1.

At least one water inlet hole 254 is set between adjacent outer scraping strips 233, and the water inlet hole 254 runs through the thickness direction of the inner barrel bottom plate 22.

[0034] In this embodiment, the number of the aforementioned cleaning discs 25 corresponds to the number of the aforementioned rags 34, which is two. Of course, if the number of rags 34 of the floor scrubber changes accordingly, such as one, three, four, etc., the number of cleaning discs 25 also changes accordingly.

[0035] In the present embodiment, an inner barrel handle 26 for lifting or flipping the inner barrel 2 for cleaning is provided in the aforementioned inner barrel body cavity 21 and along its height direction. The inner barrel handle 26 is provided on the upper surface of the inner barrel bottom plate 22 and corresponds to the upper position of the water-free area 112. Drain holes 27 are provided on the left and right sides of the inner barrel handle 26, and the drain holes 27 penetrate the aforementioned inner barrel bottom plate 22 in the thickness direction.

[0036] See also Figure 2 Combined with Figure 3 A flip foot 28 is provided on the lower surface of the aforementioned inner barrel bottom plate 22 and at a position corresponding to the aforementioned flip foot accommodating groove 1221, and a positioning plate 29 is provided on the lower surface of the aforementioned inner barrel bottom plate 22 and at a position corresponding to the positioning cavity 124 in the waterless area 112.
