Description

Inner and outer barrel type cleaning device for floor wiping rag

Technical Field

The invention belongs to the technical field of cleaning tools in daily necessities, and particularly relates to an inner and outer barrel type cleaning device for a floor wiping rag.

Background

The floor-scrubbing machine is a common automatic cleaning tool in daily life, and generally comprises a driving base and an operating lever rotatably arranged above the driving base, wherein at least one rotating disc rotatably connected through a motor is arranged in the driving base, and a rotating disc type cleaning cloth is adhered below the rotating disc. When in use, the cleaning cloth is driven to clean the ground at high speed by driving the rotating disc to rotate at high speed. The floor cleaning machine can be suitable for fine cleaning of household floors, supermarket floors and the like, and can meet the requirements of large-area efficient cleaning of warehouses, large-scale factories and the like, so that the floor cleaning machine has the characteristics of intelligence, convenience, high efficiency, practicability, labor saving and wide application. The published chinese patent documents do not contain technical information related to floor mopping machines, such as "a motor floor mopping machine" recommended by CN110393485A, "a floor mopping machine" referred to by CN209252719U, and "a floor mopping machine" introduced by CN 205493728U.

During the use of the floor cleaning machine, in order to ensure the cleaning effect and accelerate the cleaning speed, the cleaning cloth adhered under the rotating disc is frequently cleaned and tidied. The floor cleaning machine cannot be integrally placed in clean water of the water bucket to comprehensively soak and wash the cleaning cloth, otherwise, a motor and related electronic components of the floor cleaning machine are subjected to water inlet and are short-circuited and damaged after being electrified, so that the cleaning cloth can only be manually cleaned by a method of disassembling the cleaning cloth from the turntable one by one, but the cleaning mode is time-consuming and labor-consuming, certain stubborn dirt such as hair, dust and food residue particles and the like adhered to the cleaning cloth are firmly attached, the cleaning cloth needs to be continuously pulled down by hands, more sanitary problems can be caused, the skin of hands can be damaged by continuous cleaning, and a new expected effect of cleaning the cleaning cloth is difficult to achieve; in addition, although some buckets capable of cleaning the cleaning cloth of the floor mopping machine are available in the market, after the cleaning cloth is cleaned, the water in the cleaning cloth cannot be effectively squeezed out, so that the cleaning cloth is over-wet, when the floor mopping machine is further used, water drops on the cleaning cloth drop, so that a large amount of water drops are remained on the ground, the use feeling of a user is seriously affected, and the hidden danger that people are easy to slip when the user touches the ground and fall down exists.

The published Chinese patent documents show a lot of relevant technical information about a flat mop cleaning and squeezing bucket, and include a "collodion flat mop squeezing bucket" given by CN208404441U, a "mop squeezing bucket" mentioned by CN209547927U, a "multifunctional bucket" disclosed by CN209529062, and the like. Also, as the technical scheme of the cleaning device provided by "a plate-type mop and a large bucket-type cleaning device" given by the publication number CN209153472U, although the technical scheme can effectively solve the problems of inconvenient cleaning and easy carrying of the cleaning bucket, and can prevent the splashing of sewage, except for the above-mentioned problem that the cleaning cloth cannot be applied to the floor cleaning machine, the mop head needs to be put into a dewatering chamber with an inclined surface, i.e. a large upper space and a small lower space, during cleaning, and a large force is needed in the process of placing or lifting the mop head downwards, so that the operation is quite inconvenient; meanwhile, when the large water bucket type cleaning device is installed, the fixed frame needs to be installed on the bucket body through the bearing pad, so that the bearing pad needs to be installed firstly, and then the fixed frame and other parts need to be installed, the components are complex, the operation procedure is complex, and the production cost is too high.
