In general, the normal temperature water may be slowly supplied to the steam boiler 260, and the steam boiler 260 heats the normal temperature water to gradually form steam. In this embodiment, by providing the flow rate adjusting valve 250, the normal temperature water can be delivered into the steam boiler 260 in a spray manner, i.e., the normal temperature water can be sprayed into the steam boiler 260 at a preset flow rate, so that the steam can be quickly formed when the normal temperature water contacts the heated steam boiler 260.

Further, the steam supply structure 201 may include a pressure relief valve 270 provided at the steam boiler 260, and the pressure may be increased when steam is generated in the steam boiler 260, and the pressure in the steam boiler 260 may be adjusted by the pressure relief valve 270 to maintain the pressure of the steam constant.

Further, since a large amount of steam is required when the surface to be cleaned is steam-cleaned by steam, and a small amount of water is required when the surface to be cleaned is cleaned by normal temperature water, the diameter of the steam inlet 310 of the water separator 300 is larger than the diameter of the normal temperature water inlet 320.

In addition, the device posture detecting mechanism 500 may detect the posture of the floor brush assembly 14, and detect whether the floor brush assembly 14 is lifted, is inclined, and the like, so that the floor brush assembly 14 is in an abnormal state separated from the surface to be cleaned, and at this time, the steam sprayed from the water separator 300 may leak from the steam cavity and be sprayed to the user, thereby bringing danger to the user. And when the equipment posture detection mechanism 500 detects that the floor brush assembly 14 is lifted and is inclined, a signal is sent to the controller 18, and the controller 18 can timely control the water vapor supply device 200 to stop outputting steam so as to ensure the safety of a user.

Accordingly, when it is detected that the floor brush assembly 14 is separated from the surface to be cleaned, the steam supply device 200 may be controlled to stop outputting steam so that the steam supply device 200 no longer emits steam to the cleaning roller brush 400. In this way, the user can lift and transport the cleaning device 10 during its use, and the cleaning device will stop spraying steam to avoid the steam burning the user, thereby ensuring the safety of the user.

Further, a height detection sensor may be provided on the floor brush assembly 14. Further, in the step S100, the step of acquiring the current posture of the ground brush assembly 14 in real time may include the following steps:

S110, acquiring the current height value of the ground brush assembly 14 in real time through a height detection sensor, and judging the magnitude relation between the current height value and a preset height value. The predetermined height value may be a critical height value when the ground brush assembly 14 just leaves the ground.

The current height value of the floor brush assembly 14 can be detected in real time through the height detection sensor arranged on the floor brush assembly 14, and the detected current height value is compared with the preset height value to judge the size relation of the detected current height value and the preset height value, so that whether the current height value of the floor brush assembly 14 is changed or not is judged.

S120, obtaining the current posture state of the ground brush assembly 14 according to the magnitude relation between the current height value and the preset height value. Whether the current posture of the ground brush assembly 14 is abnormal, namely whether the ground brush assembly 14 is lifted or/and inclined, can be judged according to the relation between the current height value of the ground brush assembly 14 and the preset height value.

Further, in step S120, according to the magnitude relation between the current height value and the preset height value, the current posture status of the ground brush assembly is obtained, which may include the following steps:

and S122, when the current height value is larger than the preset height value, judging that the ground brush assembly 14 is in a lifted state, and obtaining that the current posture state of the ground brush assembly 14 is abnormal.

That is, when the current height value of the floor brush assembly 14 is detected to be larger than the critical height value when the floor brush assembly 14 just leaves the ground, the floor brush assembly 14 can be determined to be lifted or/and inclined, and the floor brush assembly 14 is separated from the surface to be cleaned partially or completely, so that the current posture of the floor brush assembly 14 can be judged to be an abnormal posture.

And S124, when the current height value is smaller than or equal to the preset height value, judging that the ground brush assembly 14 is in a normal grounding state, and obtaining that the current posture state of the ground brush assembly 14 is normal.

When the current height value of the floor brush assembly 14 is detected to be smaller than or equal to the critical height value when the floor brush assembly 14 just breaks away from the ground, it can be determined that the floor brush assembly 14 is not lifted and inclined and is not separated from the surface to be cleaned, so that the current posture of the floor brush assembly 14 can be judged to be a normal posture.

In addition, in order to make the detection of the current posture state of the ground brush assembly 14 accurate and reliable, a plurality of height detection sensors can be respectively arranged around the ground brush assembly 14, and the detection result is more accurate and reliable by detecting the current posture state of the ground brush assembly 14 from a plurality of positions.

In addition, the floor brush assembly 14 may be provided with a cleaning roller brush 400, and a current detecting sensor connected to the cleaning roller brush 400. In the step S100, the current posture of the ground brush assembly 14 is obtained in real time, which may include the following steps:

S130, acquiring the current value of the cleaning roller brush 400 in real time through a current detection sensor, and judging the magnitude relation between the current value and a preset current value. The preset current value may be a critical current value of the cleaning roller brush 400 when the floor brush assembly is just separated from the floor.

Similarly, the current detecting sensor provided on the floor brush assembly 14 can detect the current value of the cleaning roller brush 400 of the floor brush assembly 14 in real time, and compare the detected current value with the preset current value to determine the magnitude relationship between the detected current value and the preset current value, so as to determine whether the current value of the floor brush assembly 14 is changed.

And S140, obtaining the current posture state of the ground brush assembly 14 according to the magnitude relation between the current value and the preset current value. It can be determined whether the current posture of the floor brush assembly 14 is abnormal, i.e., whether the floor brush assembly 14 is lifted or/and tilted, according to the magnitude relation between the current value of the cleaning roller brush 400 and the preset current value.

Further, in step S140, according to the magnitude relation between the current value and the preset current value, the current posture status of the ground brush assembly 14 is obtained, which may include the following steps:

and S142, when the current value is greater than or equal to a preset current value, judging that the ground brush assembly 14 is in a normal grounding state, and obtaining that the current posture state of the ground brush assembly 14 is normal.

Similarly, when the current value of the cleaning roller brush 400 of the floor brush assembly 14 is detected to be greater than or equal to the critical current value of the cleaning roller brush 400 when the floor brush assembly 14 just breaks away from the floor, it can be determined that the floor brush assembly 14 is not lifted and inclined, and is not separated from the surface to be cleaned, so that the current posture of the floor brush assembly 14 can be judged to be a normal posture.

S144, when the current value is smaller than the preset current value, judging that the ground brush assembly 14 is in a lifted state, and obtaining that the current posture state of the ground brush assembly 14 is abnormal.

When it is detected that the current height value of the floor brush assembly 14 is smaller than the critical current value of the cleaning roller brush 400 when the floor brush assembly 14 just leaves the floor, it is determined that the floor brush assembly 14 is lifted or/and inclined to leave the surface to be cleaned, and thus the current posture of the floor brush assembly 14 can be judged to be an abnormal posture.

In addition, a level sensor may be provided on the floor brush assembly 14. In the step S100, the current posture of the ground brush assembly 14 is obtained in real time, which may include the following steps:

s150, acquiring a current inclination angle value of the ground brush assembly 14 in real time through a horizontal sensor, and judging the magnitude relation between the current inclination angle value and a preset inclination angle value.

Similarly, the current inclination angle value of the ground brush assembly 14 can be detected in real time through the level sensor arranged on the ground brush assembly 14, and the detected current inclination angle value is compared with the preset inclination angle value to judge the magnitude relation of the detected current inclination angle value and the preset inclination angle value, so that whether the current inclination angle value of the ground brush assembly 14 is changed or not is judged.

And S160, obtaining the current posture state of the ground brush assembly 14 according to the magnitude relation between the current inclination angle value and the preset inclination angle value. Whether the current posture of the ground brush assembly 14 is abnormal, namely whether the ground brush assembly 14 is lifted or/and inclined, can be judged according to the magnitude relation between the current inclination angle value of the ground brush assembly 14 and the preset inclination angle value. Typically, the floor brush assembly 14 will tilt somewhat when lifted.

Further, in the step S160, the step of obtaining the current posture of the ground brush assembly according to the magnitude relation between the current inclination angle value and the preset inclination angle value may include the following steps:

s162, when the current inclination angle value is larger than the preset inclination angle value, judging that the ground brush assembly 14 is in an inclined state, and obtaining that the current posture state of the ground brush assembly 14 is normal;

and S164, when the current inclination angle value is smaller than or equal to the preset inclination angle value, judging that the ground brush assembly 14 is in a horizontal state, and obtaining that the current posture state of the ground brush assembly 14 is normal.

Furthermore, it should be noted that the above three sets of steps, i.e., steps S110 and S120, steps S130 and S140, and steps S150 and S160, may be performed separately, or any two sets of steps may be performed simultaneously, or three sets of steps may be performed simultaneously, so that the detection result is more accurate and reliable.

Further, in step S200, when the current posture abnormality is detected, it is judged that the floor brush assembly 14 is separated from the surface to be cleaned, and the steps of:

s210, when the current posture of the floor brush assembly 14 is detected to be an abnormal posture such as an inclined state or/and a lifted state, the bottom surface of the floor brush assembly 14 is determined to be separated from the surface to be cleaned partially or completely.

When the floor brush assembly 14 is in a normal posture, the bottom surface of the floor brush assembly 14 is completely corresponding to the surface to be cleaned, and at the moment, the outlet of the rolling brush cavity (namely the steam cavity) at the bottom of the floor brush assembly is corresponding to the surface to be cleaned; when the floor brush assembly 14 is tilted or/and lifted, the bottom surface of the floor brush assembly 14 is partially or completely separated from the surface to be cleaned, and the outlet of the rolling brush chamber (i.e., the steam chamber) at the bottom of the floor brush assembly is not corresponding to the surface to be cleaned any more, and may be biased toward the user.

S220, when the bottom surface of the floor brush assembly 14 is detected to be partially or completely separated from the surface to be cleaned, judging that the steam generated by the steam supply device 200 on the floor brush assembly 14 leaks.

When the floor brush assembly 14 is in a normal posture, the bottom surface of the floor brush assembly 14 corresponds to the surface to be cleaned, so that the spraying direction of steam generated by the water vapor supply device 200 on the floor brush assembly 14 faces the cleaning roller brush 400, and the cleaning roller brush 400 cleans the surface to be cleaned with steam; when the floor brush assembly 14 is in an abnormal state, the bottom surface of the floor brush assembly 14 no longer corresponds to the surface to be cleaned, so that steam generated by the water vapor supply device 200 on the floor brush assembly 14 may leak out of the rolling brush cavity (i.e., steam cavity) at the bottom of the floor brush assembly, and may be sprayed out towards the direction of the user, thereby causing injury to the user. Accordingly, once the inclination or lifting of the brush assembly 14 is detected, it is immediately determined that the brush assembly has steam leakage so as to stop the output of steam in time.

Further, in step S300, when it is detected that the floor brush assembly 14 is separated from the surface to be cleaned, controlling the water vapor supply device to stop outputting the vapor may include the steps of:

when the ground brush assembly 14 is detected to be separated from the surface to be cleaned, the steam outlet of the steam supply device 200 is controlled to be closed, and the steam supply device 200 is controlled to stop working, so that the steam supply device 200 stops outputting steam.

That is, when it is detected that the floor brush assembly 14 is tilted or/and lifted, the steam outlet of the steam supply device 200 may be first closed so that the steam supply device 200 stops outputting steam for a short period of time. In addition, after the vapor supply device 200 stops outputting the vapor, in order to ensure the safety of the vapor supply device 200, the vapor supply device 200 can be further stopped, so that the vapor supply device 200 does not generate vapor any more, and the use safety is further ensured.
