Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1 to 11, a drying mechanism of a floor brush includes: a main machine housing 1; a base 2 for supporting and placing the main body case 1; the rolling brush component 3 is assembled in the main machine shell 1, and the main machine shell 1 can drive the rolling brush component 3 to move together under the action of external force; further comprising: an air drying mechanism arranged in the main machine shell 1; starting drive, it is including setting up circuit control system 33, the setting in base 2 or the host computer casing 1 are in air-dry circuit trigger end 4 and setting in base 2 are in air-dry circuit receiving terminal 5 in the host computer casing 1, work as air-dry circuit trigger end 4 and air-dry circuit receiving terminal 5 when putting through, circuit control system 33 control air-dry mechanism open, with to round brush subassembly 3 blow out and air-dry.

On the other hand, the rolling brush assembly 3 generally needs to be wetted in advance or to be sprayed with water during use in order to achieve a floor mopping effect. On the other hand, after the rolling brush drying device is used, the air drying mechanism is started and can directly blow the rolling brush assembly 3, so that moisture on the rolling brush assembly 3 is quickly volatilized, the efficiency of drying the surface of the rolling brush assembly 3 is improved, the breeding of microorganisms is inhibited, and the rolling brush is prevented from smelling; moreover, the rolling brush can be dried without being detached, so that the action of detaching the rolling brush by a user is reduced, the intervention degree of the user is reduced, and the intelligence and the user experience of the product are improved.

Compared with the prior art, the method has three main characteristics. Firstly, the air drying mechanism is integrated in the main machine shell 1, so that the structure of the base 2 is not required to be changed, and the integral shape of the main machine is not required to be greatly changed, thereby greatly saving the design, development and manufacturing cost; secondly, the distance between the air drying mechanism and the rolling brush assembly 3 is shorter, and the distance of an air channel is greatly shortened, so that the same fan power can achieve a better drying effect on the rolling brush assembly 3, the drying efficiency is effectively improved, and the drying time is shortened; thirdly, because the air drying mechanism is positioned in the host shell 1, the probability of false start by children is greatly reduced, and the potential safety hazard is effectively eliminated.

The preferable composition structure and use mode of the air drying mechanism are as follows: referring to fig. 3, the air drying device comprises an air drying fan 6 and an air guide cover 7, wherein an inlet end 8 of the air guide cover 7 is in butt joint and communicated with the air drying fan 6, and an outlet end 9 of the air guide cover 7 is arranged towards the rolling brush assembly 3. During the use, air-dry fan 6 starts the air supply, and wind is direct towards round brush subassembly 3 blowout behind wind scooper 7's the wind-collecting, guide effect, because the wind channel is shorter, and penetrates round brush subassembly 3 directly, therefore dry effect is better.

Regarding the installation angle of the wind scooper 7, in combination with its own characteristics, if horizontal installation is adopted, the outlet end 9 will be in a vertical direction, but since the rolling brush assembly 3 is horizontally arranged, the drying area will be too small, and the drying effect will be affected. Therefore, in the present invention, the wind scooper 7 is vertically disposed, so that the shape of the outlet end 9 is similar to the shape of the outlet grille of the common household central air conditioner.

On the other hand, most of the shell of the ground brush component part is flat, the internal space is limited, and if the air drying fan 6 is vertically installed, on one hand, the thickness of the shell is increased, and a production mold needs to be changed; on the other hand, the stress direction and the stress size of each part of the air drying fan 6 are different during vertical installation, so that the whole air drying fan is easy to damage. Therefore, in the invention, the air drying fan 6 is horizontally arranged, so that the air drying fan 6 can run more stably and reliably.

In order to rationalize the installation structure of the floor brush assembly, the inlet end 8 is arranged on the side edge 10 of the air guide cover 7 so as to butt the vertically arranged air guide cover 7 and the horizontally arranged air drying fan 6 together, and meanwhile, the air guide cover and the horizontally arranged air drying fan are more compact in layout, the overall thickness and width size do not need to be increased, and the installation of other assemblies in the shell is facilitated.

Preferably, the air drying fan 6 is a hot air fan, and can directly blow out hot air outwards, so as to further improve the drying effect.
