Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cleaning, in particular to a bottom cover assembly and an integrated water tank for a cleaning tool. BACKGROUND

[0002] Current floor cleaning tools are generally classified into two branches: air dust circulation technology represented by a vacuum cleaner and water dust circulation technology represented by a roller-type scrubber. However, due to the limitation of its working principle, the vacuum cleaner cannot clean some garbage and stains firmly attached to the ground. The "water dust circulation" scrubber drives the cleaning cylinder to wipe the ground through the operation of the motor. The cleaning cylinder usually adopts a sponge cylinder structure, and the floor cleaner is also equipped with a water supply system and a water tank to clean the cleaning cylinder, thereby perfectly realizing the cleaning of the ground. In order to clean the cleaning cylinder, a closed cleaning space communicating with the water supply system is usually provided to clean the local roller, clean water is provided to clean the cleaning cylinder, and then the sewage after cleaning the cleaning cylinder is pumped away.

[0003] The existing "air dust circulation" scrubber can only adopt a water tank system in which a clean water tank and a sewage tank are completely separated due to the limitation of the underlying technical principle. The water tank of the existing "water dust circulation" scrubber mostly adopts a traditional split design scheme of a clean water tank and a sewage tank, and there is also an integrated design scheme of a clean water tank and a sewage tank. The integrated design scheme of the clean water tank and the sewage tank allows the user to pour sewage while conveniently adding clean water, and is more convenient to use.

[0004] Chinese patents CN215937253U and CN218128365U disclose a water tank and a cleaning tool. The water tank is internally provided with a partition, which divides the water tank into a clean water area and a sewage area, and the clean water area and the sewage area are respectively provided with water level detection devices. The water tank provided in the present application combines the clean water area and the sewage area together, greatly saving the volume of the water tank, so that the cleaning tool can be designed to be small and light. Moreover, the clean water area and the sewage area are both provided with water level detection devices, which can enable the user to know in time when the clean water is used up or the sewage is full, thereby improving the cleaning effect.

[0005] Chinese patents CN217592757U and CN217524951U disclose an electrolysis assembly, a liquid storage tank and a cleaning device. The electrolysis assembly is used in the liquid storage tank, and a valve body assembly is arranged at the opening of the bottom of the liquid storage tank. The electrolysis assembly comprises a support assembly and at least two electrode pieces. The support assembly comprises a mounting structure and a conducting structure. At least one side of the mounting structure is provided with a notch for accommodating the valve body assembly. The at least two electrode pieces are arranged on the mounting structure and are electrically connected to the conducting structure, respectively. The electrolysis assembly provided by the present application can accommodate the valve body assembly in the notch of the electrolysis assembly when the electrolysis assembly is installed in the liquid storage tank, so that the electrolysis assembly can be closer to the opening of the bottom of the liquid storage tank, and the liquid level for electrolysis is lower, and the electrolysis efficiency is higher.

[0006] In the prior art, the water electrolysis module is integrated in the water tank of the split type water tank system or the integrated type water tank system to sterilize and disinfect the clean water for cleaning the floor. The power taking structure and the water outlet of the water electrolysis module are arranged on the peripheral wall and the bottom wall of the clean water tank at a very short linear distance. When the clean water tank is removed, the unused clean water will inevitably drip into the corresponding accommodation cavity of the cleaning tool through the clean water outlet. Since the position of the power taking electrode is only slightly higher than the lowest position of the water tank, the dripping water is easy to cause short circuit between the power taking electrodes of the water electrolysis module. If a water electrolysis module is separately added to the pipeline of the clean water output of the water circulation passage, higher requirements for the volume of the water electrolysis module and the corrosion resistance of the corresponding pipeline will be put forward. On the other hand, after the water electrolysis module is integrated in the water tank, since the use characteristic of the water tank is to be frequently removed to drain sewage and add clean water, how to realize the stable electrical connection and the quick and stable disconnection of the water electrolysis module is also a difficult problem to be solved. On the other hand, after the water electrolysis module is added in the water tank, how to waterproof and conveniently replace and maintain the terminal of the power supply line of the water electrolysis module while ensuring the air tightness of the water tank system also needs to be further improved.
