It should be noted that the water level sensor 131 may be a non-contact sensor, such as a capacitive liquid level sensor or an ultrasonic liquid level sensor, and of course, other types of water level sensors 131 may also be used, and only the water level housing in the waste water tank 120 needs to be accurately detected, which may be determined according to actual situations, and is not limited specifically herein.

In some embodiments of the present invention, the housing 110 is provided with an installation part 111 at one side of the sump tank 120, and the water level sensor 131 is installed at the installation part 111. The mounting portion 111 may be a mounting plate, and the water level sensor 131 may be mounted to the mounting plate by a fastening member such as a screw or a bolt. The conductive medium 132 is located between the water level sensor 131 and the wastewater tank 120, and one end of the conductive medium 132 abuts against the detection end of the water level sensor 131, and the other end contacts with the outer sidewall of the wastewater tank 120; alternatively, the conductive medium 132 may be connected to the mounting plate, and one end of the conductive medium may abut against the detection end of the water level sensor 131 and the other end thereof may abut against the outer sidewall of the sump 120.

Referring to fig. 4 again, in some embodiments of the present invention, the housing 110 is provided with a mounting groove 112, the waste water tank 120 is disposed in the mounting groove 112, a side wall of the mounting groove 112 constitutes the mounting portion 111, and the water level sensor 131 is mounted on the side wall of the mounting groove 112. When the sump 120 is disposed in the mounting groove 112, one end of the conductive medium 132 abuts against the sensing end of the water level sensor 131, and the other end abuts against the outer sidewall of the sump 120, so that the stability of the contact between the sensing end of the water level sensor 131 and the sump 120 can be improved, the sump 120 and the water level sensor 131 can stably transmit water level signals, and the accuracy of the water level sensor 131 detecting the water level in the sump 120 can be improved. In the present embodiment, the side wall of the mounting groove 112 is the mounting portion 111, so that the structure inside the housing 110 can be made more compact, and the mounting space can be saved.

Referring to fig. 4 and 5, in some embodiments of the present invention, the side wall of the mounting groove 112 is provided with a mounting hole 1121 for mounting the water level sensor 131, and the water level sensor 131 is clamped in the mounting hole 1121. It should be noted that the structure and size of the mounting hole 1121 are matched with the size and structure of the water level sensor 131, so that the water level sensor 131 can be stably clamped in the mounting hole 1121, and the stability of the detection of the water level sensor 131 when the floor washing machine 100 works is improved. It should be further noted that the water level sensor 131 is fixed in the mounting hole 1121 in a snap-fit manner.

Referring to fig. 5 again, in some embodiments of the present invention, the water level sensor 131 is installed in the installation hole 1121, and the detection end of the water level sensor 131 is flush with the inner wall of the installation portion 111, i.e. flush with the inner wall of the installation groove 112, the conductive medium 132 is adhered to the detection end of the water level sensor 131, for example, the conductive medium 132 can be adhered to the detection end of the non-contact sensor through a double faced adhesive tape or a glue solution. One end of the conductive medium 132 facing away from the water level sensor 131 abuts against an outer sidewall of the sump 120. Among the technical scheme of this application, installation department 111 is equipped with mounting hole 1121, and level sensor 131 installs in mounting hole 1121, and level sensor 131's sense terminal and installation department 111's inner wall parallel and level to can reduce the size of mounting groove 112, with the inside installation space of practicing thrift casing 110, make floor cleaning machine 100 inner structure compacter.

In some embodiments of the present invention, the conductive medium 132 is an elastic conductive member, the sewage tank 120 is detachably mounted in the mounting groove 112, and a gap is formed between the outer sidewall of the sewage tank 120 and the sidewall of the mounting groove 112, so as to facilitate the detachment and installation of the sewage tank 120. One end of the elastic conductive member abuts against the outer sidewall of the sewage tank 120, and the other end abuts against the detection end of the water level sensor 131, and the conductive medium 132 can more stably abut against the sewage tank 120 and the water level sensor 131 by using the elastic conductive member.

It should be noted that the elastic conductive member may be a conductive sponge, one end of the conductive sponge is adhered to the detection end of the water level sensor 131, and the other end of the conductive sponge abuts against the sewage tank 120. The conductive sponge has good conductivity and is convenient to process. It should be noted that other conductive materials, such as conductive rubber, may also be used, and have good conductivity and elasticity. Again, the specific material of the conductive medium 132 is not particularly limited and may be determined according to the actual situation.

The sensing unit can detect the water level in the sump 120, and the controller can receive a water level signal of the sensing unit and execute different commands according to different water level signals. For example, the controller is connected to an alarm, receives the water level signal detected by the sensing unit, and when the water level in the sewage tank 120 reaches a first preset value, that is, the first preset value is reached, sewage needs to be treated in time, and the controller can control the alarm to give an alarm to remind a user of treating in time. Or when the sensing unit detects that the water level in the sewage tank 120 reaches the second preset value, that is, the sewage tank 120 is full of water, the floor washing machine 100 cannot normally perform floor washing work at this time, and after receiving the water level signal, the controller can control the floor washing machine 100 to stop working and control the alarm to give an alarm to remind a user of timely treating sewage.

Referring again to fig. 2 and 3, in some embodiments of the present invention, the housing 110 is provided with a first connection portion (not shown), the waste water tank 120 is provided with a second connection portion 121 which is matched with the first connection portion, and the waste water tank 120 is matched with the housing 110 by the first connection portion and the second connection portion 121. It should be noted that the second connecting portion 121 is configured as a clamping column, the first connecting portion on the housing 110 is configured as a clamping hole, and the clamping hole is configured with the clamping column, so that the sewage tank 120 can be detachably clamped to the housing 110, and the sewage tank 120 can be conveniently detached and installed by clamping, thereby improving the user experience. The number of the clamping columns can be one, two, three or more, and only the sewage tank 120 needs to be stably clamped in the casing 110, which is not specifically limited herein.

It should be noted that one end of the clamping column is connected with a button 122, and the button 122 is pressed to drive the clamping column to be separated from the clamping hole, so that the sewage tank 120 can be detached from the housing 110. That is, the inside spring that can set up of button 122, the expansion end butt of spring in button 122, the stiff end butt of spring in sewage case 120, the spring can promote the button 122 and slide to drive the joint post and upwards slide, and go deep into the joint downthehole, thereby make sewage case 120 joint on casing 110. When the sewage tank 120 needs to be disassembled, the key 122 is pressed downwards, so that the clamping column is driven to move downwards, and the clamping hole slides out. Of course, the waste water tank 120 may be fastened to the housing 110 by means of a snap.
