Referring to fig. 4, the principle of gravity center change in the cleaning process of the household floor cleaning device according to an embodiment is as follows:

when the clean water tank and the sewage tank of the household floor cleaning device are emptied, the gravity center is at the point A, the coordinates are (AX, AY), and the weight is W0; after the clean water tank is filled with water, the gravity center of the clean water is at a point D, coordinates are (DX and DY), and the weight of the clean water is W1; after the sewage tank is filled with water, the gravity center of the sewage and the garbage is at the point E, the coordinates are (EX, EY), and the weight of the sewage and the garbage is W2; when the clean water tank is full of water and the sewage tank is empty, the center of gravity of the household floor cleaning device main body is at a point B, coordinates are (BX, BY), and the weight is W01 which is W0+ W1; when the clean water tank is empty and the sewage tank is full, the center of gravity of the household floor cleaning device body is at the point C, the coordinates are (CX and CY), and the weight is W02 which is W0+ W2.

Then, W0 × AX + DX W1 ═ BX × W01 ═ BX (W0+ W1)

BX (W0 AX + DX W1)/(W0+ W1), DX < AX since DX is below the center of gravity of the body and BX < AX

W0*AY+DY*W1＝BY*W01＝BY*(W0+W1)

BY (W0 AY + DY W1)/(W0+ W1), BY < AY since DY < AY is below the center of gravity of the body in the clear water tank

Point B is below point a, i.e., center of gravity B is lower than center of gravity a.

Similarly, W0 × AX + EX W2 ═ CX × W02 ═ CX (W0+ W1)

CX (W0 AX + EX W2)/(W0+ W2), CX > AX since EX > AX since the sump is above the center of gravity of the body

W0*AY+EY*W2＝CY*W01＝CY*(W0+W1)

CY (W0 AY + EY W1)/(W0+ W1), CY > AY since EY > AY since the sump is above the center of gravity of the main body

Therefore, point C is above point A, i.e. the center of gravity C is higher than the center of gravity A.

According to the analysis, the clean water tank is filled with water, the sewage tank is emptied at the same time, the household floor cleaning device is operated to carry out cleaning work, clean water in the clean water tank is continuously sprayed to the surface to be cleaned through the water pump, and meanwhile, the clean water is washed and then is sucked into the sewage tank along with the garbage; at the moment, clear water in the clear water tank is gradually reduced, the weight of the clear water is reduced, meanwhile, sewage and garbage in the sewage tank are gradually increased, and the weight of substances in the sewage tank is increased. The centre of gravity of the main body of the domestic floor cleaning device is shifted from B to A to C, i.e. from low to high. When the user operates, the bearing capacity is changed from light to heavy along with the deepening of cleaning, the real situation of cleaning work is reflected, and the user experience is enhanced.

In the invention, the sewage tank is arranged above the sewage tank, the clean water tank is arranged at the lowest part, and the gravity center of the household floor cleaning device is positioned at a lower position before cleaning is started, so that the operation of a user is very easy, and no load feeling exists; because the transparent clear water tank is arranged at the bottom and is close to the ground, a user can see through the clear water tank to observe the dirt degree of the ground in real time, the water spraying amount and the cleaning strength are increased according to the actual situation, and the problems of repeated cleaning and multiple times caused by insufficient cleaning degree are solved; the sewage tank is far away from the ground and is closer to a user, so that the user can conveniently check the condition in the sewage tank in real time, the cleaning state of the household ground cleaning device can be more intuitively confirmed, and the experience of the user is greatly enhanced.

The above examples merely represent several embodiments of the present invention, which are described in more detail and in more detail, but are not to be construed as limiting the scope of the invention.
