Because the power consumption of each surface cleaning machine is fixed, the cleaning area is determined by the power of a roller brush motor, the rotating times and the width of a cleaning roller, the cleaning working time of a common household set by the common surface cleaning machine in the industry is 25-40 minutes, and the conventional time of the common automatic cleaning work is 2-6 minutes (strong washing), the cleaning roller can be automatically cleaned, even if the designed power of a battery is completely consumed in the cleaning working period, the power consumption of the automatic cleaning is at most 24% of the power of the battery and at least 5%, so that the nominal power residual quantity of the battery pack is set to be at least 10% of the nominal power and not more than 30% of the nominal power to meet the cleaning requirements of the common household, and the matching ensures that the surface cleaning machine has enough power to meet the cleaning work, meanwhile, the residual power for automatic cleaning and drying is left, then the automatic cleaning is carried out, the charging is carried out after the automatic cleaning is finished, the charging is reminded, the water charging is more intelligent, and the next preparation for the next cleaning work of the next time can be fully realized, and the problem that the residual power consumption is insufficient to support the next cleaning work and the cleaning work can be interrupted due to forget is avoided; meanwhile, the problem that the service life of the battery is damaged if the charging is carried out in the way, as much residual electric quantity is generated and more residual electric quantity is generated, not only is a resource waste generated; in addition, what do the nominal electric quantity of battery is too big, and the volume of the fuselage that the battery package occupied is also great for surface cleaning machine weight also increases, and general power source system all sets up the upper portion at the fuselage, and the great heavier focus that leads to shifts up, according to lever principle, then the customer needs great power to control surface cleaning machine, just is unlikely to drop from the hand, experiences the sense not good, leads to surface cleaning machine work to be hard to use inconveniently.

2. The clear water tank is fixedly arranged in the machine body, the sewage tank is detachably arranged on the machine body, the equivalent diameter of the outer contour formed by the sewage tank arranged on the machine body is D, the equivalent diameter of the power source system is D, D/D is more than or equal to 0.7 and less than or equal to 1, and D is more than or equal to 7cm and less than or equal to 9cm; or the clear water tank and the sewage tank are detachably arranged on the machine body and are respectively positioned at the front side and the rear side of the machine body, the equivalent diameter of the outer contour formed by arranging the clear water tank and the sewage tank on the machine body is D, the equivalent diameter of the power source system is D, D/D is more than or equal to 0.7 and less than or equal to 1, and D is more than or equal to 8cm and less than or equal to 10cm. Due to the structure, the nominal electric quantity of the battery pack is reasonable, so the occupied volume of the battery pack is not large, the weight of the surface cleaning machine is reduced, meanwhile, the clean water tank is arranged in the machine body, the clean water tank does not need to be disassembled and assembled, the interfaces between the clean water tank and the machine body are reduced, the water flow is smoother, the possibility of water leakage of the clean water tank at the interfaces is reduced, and if the machine body is provided with the water filling port communicated with the clean water tank, a customer does not need to lift the water tank to fill water, the water filling is not only convenient, but also the automatic control is easy to realize; meanwhile, the structure reduces the whole volume of the machine body and lightens the whole weight of the machine body under the condition of meeting the requirement that the capacity of the clean water tank and the capacity of the sewage tank are not changed, meanwhile, the structure of the clean water tank does not influence the modeling design of the machine body, the space is reasonably utilized, the equivalent diameter of the machine body meets the requirement that D is more than or equal to 7cm and less than or equal to 9cm, the machine body is lightened and miniaturized, even the capacities of the clean water tank and the sewage tank can be increased, the machine body can still keep reasonable volume and weight, and the light weight is achieved. In addition, the clear water tank is fixedly arranged in the machine body, so that the balance weight of the machine body can be increased, the gravity centers of the machine body and the sewage tank are balanced, the change of the gravity center of the machine body is small along with the increase of sewage in the sewage tank, a customer cannot feel unstable, convenience is brought to the customer, the unbalance of the machine body cannot be caused due to the change of the gravity center of the sewage tank, the machine body is stable to use during work and convenient to clean, and when the machine body is dragged to the cleaning seat after the use is finished, the machine body is convenient to drag, and the water filling port is arranged on the machine body, so that the automatic water filling on the cleaning seat can be realized more conveniently; in addition, because place the fuselage intracavity of fuselage in the clear water tank, then the clear water tank can more press close to the power supply system, perhaps press close to the soil pick-up motor in the power supply system, thereby can play the effect of water-cooling for the soil pick-up motor, guarantee the operational environment of soil pick-up motor, promote the working property of soil pick-up motor, and simultaneously, when accomplishing cleaning, resource-wasting does not, remind client to charge after automatic cleaning work and/or stoving work are accomplished, make more intelligent and energy-conserving, client experience feels better.

When D is greater than 9cm, although the cleaning area can be increased by increasing the capacity of the clean water tank and the sewage tank, the excessive volume not only wastes the space of the machine body, but also reduces the weight, is a waste of resources, and is inconvenient for the old and children to use. When D is less than 7cm, although the weight is reduced, the volume is too small, the capacity of the clean water tank and the sewage tank cannot be met, and therefore the cleaning in a large area is not facilitated; meanwhile, in order to meet the requirement of the cleaning area of half of families, the clear water tank and the sewage tank are designed to be large enough, so that the layout space of pipelines and circuits in the machine body is small, and the design of the whole machine model is not facilitated.

3. The power source system is internally provided with a vacuum motor, the rated power of the vacuum motor is W1, W1 is not less than 120W and not more than 150W, the power consumption of the surface cleaning machine is minimum under the condition that the vacuum motor has enough suction force, so that the power consumption is minimum, the surface cleaning machine can complete at least one effective cleaning, enough electric quantity can be still provided for the surface cleaning machine to perform automatic cleaning work, and the automatic cleaning work of the surface cleaning machine can be completed.

5. The liquid supply assembly further comprises a water pump, and the rated power of the water pump is W3, W2 is more than or equal to 15W and less than or equal to 20W, so that when the surface cleaning machine performs cleaning and/or self-cleaning work, the water supply amount of the water pump is optimal, and water and energy are saved at the most.

6. The surface cleaning machine is used for cleaning, and the water consumption in unit area is 9ml/m ² ～10ml/m ² The surface cleaning can meet the requirement of one-time conventional household cleaning, the best cleaning effect can be achieved by using the least water in the working process, and the product is produced under the condition of ensuring the cleaning effectThe raw sewage is the least, the sewage suction is easier after cleaning (or the sewage suction is carried out while cleaning), no residue is generated in the sewage suction process, and the self-cleaning process of the surface cleaning machine is the same, so that the cleaning and automatic cleaning effects are good, and the energy is saved and the efficiency is high. Let us consider the area in the cleaning chamber as 100m ² Assuming that the actual cleaning area is 70m at the maximum, for example, in the room (D) ² (actually much less than this value) and the amount of water required to be consumed is 630ml to 700ml, we can set the volume of the clean water tank to 650ml, which can ensure that the water consumption is enough to ensure that the surface cleaning machine has the minimum bare machine volume, lightest weight and lighter weight and is more energy-saving under the condition that the water in the clean water tank is enough.

The power consumption of the surface cleaning machine is fixed by designing the power consumption per unit area of the surface cleaning machine for cleaning work to be 30mAh/m ² ～40mAh/m ² The surface cleaning machine can meet the cleaning requirement of a conventional household, the power consumption is minimum under the condition of keeping the cleaning effect, and the water consumption in unit area is 9ml/m ² ～10ml/m ² More energy-saving, we still use the cleaning room inner area as 100m ² The room of (2) for example, the power consumption of the surface cleaning machine is 2100mAh, so that the nominal power of the battery pack is set to 3000mAh, the surface cleaning machine finishes one cleaning operation, water in the clean water tank is used up, the residual power is 900mAh, the surface cleaning machine can sufficiently finish self-cleaning operation (water can be automatically added during self-cleaning), the roller brush of the cleaning roller can also be dried or air-dried sufficiently, and then charging is carried out, so that sufficient preparation can be made for next cleaning operation. Such a setting will save more energy under the condition of guaranteeing cleaning effect and self-cleaning effect.

8. The clear water tank penetrates through the machine body, the sewage tank is arranged on the front side of the machine body, the capacity of the clear water tank is V1, and V1 is larger than or equal to 500ml and smaller than or equal to 900ml. The power source system is arranged beside the clean water tank in parallel, or above the clean water tank, or the clean water tank is arranged around the power source system, so that at least the clean water tank is arranged or contacted around the power source system, and therefore, the temperature of electric devices such as a motor or a battery pack in the power source system can be reduced through the clean water tank, the working environment temperature of the electric devices can be ensured, and the good working performance of the electric devices can be ensured; the capacity of the clear water tank meets that V1 is more than or equal to 500ml and less than or equal to 900ml, the space in the machine body is more reasonably utilized, the cleaning water with a larger area can be realized, meanwhile, the clear water tank has reasonable capacity and runs through the machine body, the gravity center can be reasonably, uniformly and sequentially transferred on the machine body, and the problem of unstable use caused by sudden change of the gravity center due to change of water flow can be solved; meanwhile, the contact area of the clear water tank and the power source system is ensured, so that the power source system is cooled and radiated better. When V1 is less than 500ml, the volume of the clean water tank is small, the clean area of a common family can not be reached, if the clean water tank is placed higher, the water supply path is lengthened, the water supply for the floor brush is not facilitated, and the gravity center of the machine body is influenced; if the arrangement is lower, the water filling port is also lower, so that water is inconvenient to add, and inconvenience is brought to customers. When V1 is greater than 900ml, the clear water tank has large capacity, so that the volume of the machine body is overlarge, the requirement of the cleaning area of a common family is exceeded, after cleaning is finished, more water is remained, the waste of resources is caused, peculiar smell can be generated when the residual water is stored for a long time, and the next cleaning work is not facilitated.
