Description

Technical Field

[0001] The present application belongs to the technical field of cleaning equipment, and in particular, relates to a cleaning head for a cleaning tool and a cleaning tool. Background Art

[0002] With the development of modern technology, there are many kinds of floor cleaning tools, including brooms, mops, floor wipes and vacuum cleaners. Vacuum cleaners are very common floor cleaning tools, but they make a lot of noise, which makes people very uncomfortable. And the way they clean garbage is just to suck the garbage into the garbage box.

[0003] Brooms, mops, and floor wipes are sweeping cleaning tools, which generally have a fixed cleaning part. Their cleaning ability is determined by the dirt removal and dirt absorption ability of the cleaning part. Since the cleaning part is contaminated once it comes into contact with the dirty ground, the cleaning ability is gradually weakened in the subsequent cleaning process, especially when cleaning a large area continuously, it is impossible to clean thoroughly. Therefore, these cleaning products must be rinsed frequently, which is very troublesome.

[0004] For Chinese consumers, sweeping and mopping are both necessary for cleaning the floor. Sweeping or mopping alone cannot achieve a thorough cleaning of the floor. However, these existing sweeping and mopping machines either require constant washing or have a complex structure and are very expensive, which makes ordinary consumers reluctant to buy them.

[0005] Moreover, existing common floor cleaning tools can only clean dry garbage (brooms or vacuum cleaners, etc.) or can only be used to clean liquid garbage (mops, floor wipes, etc.). The cleaning effect of the tools on mixed dry and wet garbage, especially sticky garbage (such as syrup, ketchup, etc.) is either very poor or very laborious (for example, using a rag, which requires multiple washings), which can be said to be helpless. Cleaning tools that combine sweeping, mopping, and washing can not only clean dry garbage, but also achieve very good cleaning effects on extremely difficult-to-handle sticky garbage such as ketchup and chocolate sauce, thereby greatly facilitating users.

[0065] The inventors have found that during the use of existing integrated cleaning tools such as sweeping, mopping and washing, on the one hand, the garbage cleaned by the roller is easily entered into the sink after being cleaned inside the cleaning tool, which can easily clog the waterway; when larger garbage enters the sink, the sponge roller needs to be disassembled to take out the garbage, which is complicated to operate; on the other hand, when the brush roller is being replaced or the garbage box is being cleaned, many peripheral components need to be taken out first before the brush roller or the garbage box can be taken out, which makes the operation complicated and affects the user experience.

[0066] In order to solve the above problems, the present application provides a cleaning head and a corresponding cleaning tool, which can conveniently remove garbage from the sink, reduce the risk of waterway blockage, simplify the operation of the brush roller and the garbage box, and improve the user experience. The solution of the present application will be described in detail below in conjunction with the accompanying drawings.
