Still taking the cleaning robot 100 with a body height H2 of 87mm as an example, please refer to fig. 17, when the width B1 of the mop plate is 175mm, the length C1 of the mop plate is 400mm, the bottom area A1 of the mop plate is the product of the width B1 of the mop plate and the length C1 of the mop plate, a1=c1×b1; the length C2 of the bottom surface of the airframe is 400mm, and the width B2 of the bottom surface of the airframe is 400mm, and then the bottom area A2 of the airframe is the product of the length C2 of the bottom surface of the airframe and the width B2 of the bottom surface of the airframe, a2=c2×b2; the lifting height H1 of the mopping head is less than or equal to 20mm, and at this time, in order to reasonably arrange the machine body 10, the bottom area A1 of the mop plate and the lifting height H1 of the mopping head are equal to each otherThe ratio between the product and the product of the fuselage floor area A2 and the fuselage height H2 is in a preset range, which is calculated as:
in one embodiment of the present disclosure, the lifting height H1 of the mopping head is greater than or equal to 15mm. The floor mopping head is in a mopping raised position such that the floor mopping head is in a non-mopping state, which includes a scene, and the cleaning robot 100 cleans carpets. The cleaning robot 100 lifts the mopping head when cleaning the carpet, avoiding the mopping head from contaminating the carpet. When the cleaning robot 100 is driven onto a carpet, if the carpet is a soft or long hair carpet, the cleaning robot 100 may sink into the soft or long hair of the carpet, the distance between the bottom surface of the machine body and the bottom surface of the mop plate 41 and the carpet becomes short, and if the lifting height H1 of the mopping head is not high enough, the mop plate 41 may contact the carpet, causing carpet pollution. At the moment, the floor mopping working head needs to be lifted to a higher height, and the lifting height of the floor mopping working head is larger than 15mm, so that the situation of polluting long-hair or soft-hair carpets can be effectively avoided. The mopping head is in a non-mopping state and also includes a scene where the cleaning robot 100 passes over an obstacle. The floor mopping head is raised when the cleaning robot 100 passes over an obstacle, avoiding that the floor mopping head contacts the floor to interfere with the cleaning robot 100 passing over the obstacle. When the cleaning robot 100 passes over an obstacle, the body 10 is inclined at a certain angle, and if the lifting height H1 of the mopping head is not high enough, the mop plate 41 is still in contact with the ground, and the cleaning robot 100 is disturbed to pass over the obstacle. At this time, the floor mopping head needs to be lifted to a higher height, and the lifting height of the floor mopping head is greater than 15mm, so that the floor mopping head can be effectively prevented from being interfered when the cleaning robot 100 spans an obstacle. In general, the carpet is fully paved, the highest height is about 15mm, cleaning robots with different specifications possibly sink 5-15mm in the carpet, and the lifting height of the mopping working head of the cleaning robot is larger than 15mm, so that the mopping working head can not touch the carpet when the cleaning robot drives on the carpet, and the carpet is prevented from being polluted.
Further, the lifting height H1 of the mopping head is related to the distance from the bottom surface of the machine body to the carpet or the ground. For the setting of the lifting height H1 of the floor mopping head, the distance from the bottom surface of the machine body to the carpet or the ground should be referred to, the closer the distance from the bottom surface of the machine body to the carpet or the ground is, the higher the lifting height H1 of the floor mopping head is, the farther the distance from the bottom surface of the machine body to the carpet or the ground is, and the lower the lifting height H1 of the floor mopping head is. The lifting height H1 of the floor mopping head is set in this way, so that the floor mopping head can effectively avoid polluting the carpet or interfering with the cleaning robot 100 to span the obstacle when the cleaning robot 100 drives onto the carpet or spans the obstacle.
Specifically, the distance from the bottom surface of the main body to the carpet or the floor is related to the weight of the cleaning robot 100 itself and the diameters of the universal wheels 21 and the driving wheels 22 of the cleaning robot 100. It will be appreciated that the lighter the cleaning robot 100 weight, the larger the diameters of the driving wheel 22, the universal wheel 21 of the cleaning robot 100, the farther the bottom surface of the main body is from the carpet or the floor; the heavier the cleaning robot 100, the smaller the diameters of the universal wheel 21 and the driving wheel 22 of the cleaning robot 100, and the closer the floor of the machine body is to the carpet or the floor. The lighter the cleaning robot 100 is, the larger the diameters of the driving wheel 22 and the universal wheel 21 of the cleaning robot 100 are, and the lower the lifting height H1 of the mopping head can be set; the heavier the cleaning robot 100, the smaller the diameters of the universal wheels 21 and the driving wheels 22 of the cleaning robot 100, the higher the lifting height H1 of the mopping head needs to be set.
When the cleaning robot 100 drives on a carpet to clean the carpet, if the carpet is a long-hair or soft-hair carpet, the cleaning robot 100 may sink into the carpet, and the cleaning robot 100 may sink into the carpet, that is, the universal wheels 21 and the driving wheels 22 of the cleaning robot 100 may sink into the carpet. The distance from the bottom surface of the body to the carpet is related to the depth to which the cleaning robot 100 is recessed into the carpet. The deeper the cleaning robot 100 is sunk into the carpet, the smaller the distance from the bottom surface of the machine body to the carpet, the higher the lifting height H1 of the mopping head needs to be set, the shallower the cleaning robot 100 is sunk into the carpet, the larger the distance from the bottom surface of the machine body to the carpet, and the lower the lifting height H1 of the mopping head can be set. The depth to which the cleaning robot 100 is sunk into the carpet is related to the weight of the cleaning robot 100, and the softness of the carpet. It will be appreciated that the greater the weight of the cleaning robot 100, the softer the carpet, and the greater the depth of the cleaning robot 100 plunging into the carpet.
