[0029] See also Figure 1-4 The utility model provides a technical solution: a liquid level detection structure of a floor brush water tank, comprising:

[0030] Floor brush body 1;

[0031] The liquid level detection structure 7 is arranged in the sewage tank 2 of the floor brush body 1 and is used for water level detection and prompt alarm of the sewage 5 in the sewage tank 2. The sewage tank 2 is provided with a sewage inlet 3 and an exhaust gas collection port 4. The sewage tank 2 is provided with a cavity 6 connected to the sewage inlet 3. The liquid level detection structure 7 is floated on the sewage 5 in the cavity 6.

[0032] The liquid level detection structure 7 includes a float 8 floating on the sewage in the chamber 6, a magnet 10 and an alarm 11 arranged in the float 8, and a fixed magnet 9 fixed to the bottom of the chamber.

[0033] A slide groove is provided on at least one side of the float 8 and the cavity 6. A positioning block 81 is provided on the side of the float 8, and a stopper 61 corresponding to the positioning block 81 is provided on the top of the cavity 6 to limit the float 8.

[0034] An active cavity is set in the float 8, the alarm 11 is fixed on the top of the active cavity, and the magnet 10 is slidably connected in the active cavity. In this embodiment, a pressure sensor is set at the bottom of the alarm 11, and the water level threshold of the sewage tank 2 can be determined. At this time, the pressure value displayed on the pressure sensor is the pressure threshold. When the pressure threshold of the pressure sensor is equal to or lower than the threshold, the alarm 11 will sound a water level alarm to remind the user to clean the sewage tank 2. The alarm method can be a loudspeaker voice broadcast or an indicator light display. The magnet 10 and the fixed magnet 9 are arranged with the same poles opposite to each other. In addition, the surfaces of the magnet 10 and the fixed magnet 9 are both provided with a water-proof layer to prevent the corrosion of the magnet by sewage and ensure a longer service life of the magnet.

[0035] The working principle of the liquid level detection structure of the floor brush water tank of this embodiment includes: before use, according to the needs, based on the sewage water level threshold, set the pressure threshold of the corresponding liquid level detection structure 7. When the floor brush is cleaned, the generated sewage 5 enters the sewage tank 2 through the sewage inlet 3, and the collected waste gas is sucked into the air filtration system of the floor brush through the waste gas collection port 4 to collect dust and other impurities. When in use, when the water level of the sewage 5 in the sewage tank 2 is lower than the set threshold, it is in use state 1 (such as Figure 2 , 3 ), the float 8 floats on the sewage 5 in the chamber 6, and the magnet 10 is subjected to the magnetic repulsion of the fixed magnet 9, overcomes the gravity and moves up to the top of the active chamber of the float 8 and abuts against the pressure sensor of the alarm 11, forming a pressure greater than the pressure threshold on the pressure sensor. When the water level of the sewage 5 further rises and the sewage level is higher than the set water level threshold, the distance between the two magnets increases, and the mutual magnetic repulsion decreases, causing the magnet 10 to move down in the active chamber, and the pressure value obtained by the pressure sensor drops to below the pressure threshold, which is the use state 2 (such as Figure 4 ), at this time, the alarm 11 will sound an alarm to inform the user that the water level in the sewage tank is too high and needs to be cleaned to ensure the normal use of the floor brush.

[0036] In summary, due to the adoption of the above technical solution, the liquid level detection structure of the floor brush water tank of this embodiment has the following beneficial effects compared with the prior art:

[0037] The floor brush has the function of water tank water level detection and alarm. Through the water level threshold before use and the pressure threshold of the liquid level detection structure, when the water level is higher than the water level threshold, the two magnets and float cooperate with the pressure sensor of the alarm to provide real-time water level feedback and alarm to inform and remind the user of the water level and ensure the normal and efficient use of the floor brush. The structural principle is simple, the feedback is accurate, and it can meet the needs of different users.

[0038] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
