As shown in fig. 4 to 6, the first cleaning head 231 is configured to be insertable into the hard tube housing 221 of the hard tube 22 in the axial direction of the hard tube 22; the first cleaning head 231 is not provided with a "lift pin" as in the second cleaning head; the first cleaning head 231 is inserted into the hard tube 22 and does not trigger the second switching element 2252, i.e. the main control board 3 does not receive a signal triggering the activation of the locking circuit.

The control program of the main control board 3 comprises a plurality of working modes for controlling the surface cleaner, and the working modes can enable the surface cleaner to be better suitable for the current cleaning work.

The host 1 is also provided with a man-machine interaction interface 18, and the man-machine interaction interface 18 is in signal connection with the main control board 3; the man-machine interface 18 comprises a plurality of operation mode selection keys 181 which can be selected by a user, and when the user triggers one of the operation mode selection keys 181, the main control board 3 can control each controlled component on the surface cleaning machine to work according to the corresponding operation mode.

The plurality of operating modes in this example may include: cold water & dust collection mode, steam sterilization mode, dust collection mode, etc.; wherein each mode containing steam is operated corresponding to the second water pump, namely the second water pump inputs water from the water tank into the steam generator for heating Cheng Gaowen and outputting steam; each mode containing cold water works corresponding to the first water pump, namely the first water pump directly outputs water from the water tank to the outside; each mode of dust collection is contained, and the mode corresponds to the starting work of the suction motor. Among the plurality of operation mode selection keys, the corresponding operation mode selection key 181 containing dust collection is set to be unusable at the time of the lock circuit activation.

In this example, an indicator light (not shown) is disposed at each operation mode selection key 181; when a certain working mode is in an unavailable state, the indicator lamp corresponding to the working mode selection key is in an off state.

With the aid of the cleaning head detecting means 225 including the above-described structure, when the first cleaning head 231 is attached to the other end of the hard tube 22, since the second switching element 2252 is not activated, the signal received by the main control board 3 is 0; while when the second cleaning head 232 is attached to the other end of the hard tube 22, the second switching element 2252 is triggered, the main control board 3 will receive a current signal generated as a result of triggering the second switching element 2252, the main control board 3 will activate the lock circuit based on the current signal, the suction motor 14 is disabled from being activated, so that a plurality of modes including the suction function are disabled from being selected; for example, corresponding to the above-mentioned plurality of operation mode selection keys 181, the user can select only the operation mode selection key 181 corresponding to the steam sterilization mode, and the other operation mode selection keys are all in the lock unavailable state, and the corresponding indicator lamp is also turned off.

In the application, the second cleaning head of the fluid nozzle can be identified by utilizing the cleaning head detection device, so that the suction motor cannot participate in the work, and all the working mode selection keys which need to start the work of the suction motor are unavailable; therefore, the user does not need to manually close the suction motor, and the use is more convenient.

The technical scheme of the application can be applied to cleaning equipment such as vertical type cleaning equipment and handheld type cleaning equipment besides horizontal type cleaning equipment.

The foregoing has outlined and described the basic principles, main features and advantages of the present application. It will be appreciated by persons skilled in the art that the present application is not limited to the embodiments described above, and that the embodiments and descriptions described herein are merely illustrative of the principles of the application, and various changes and modifications may be made therein without departing from the spirit and scope of the application, which is defined in the appended claims, specification and their equivalents.
