For those of ordinary skill in the art, the specific meaning of the above terms in the present disclosure can be understood according to the specific circumstances.

[0027] Referring to Figures 1-6 As shown, the anti-backflow dirt cleaning device according to the present disclosure is schematically shown, mainly used for corresponding cleaning equipment such as floor cleaning machine, floor wiping machine, etc. The dirt cleaning device includes a container body 1, which can be a barrel, a box or other suitable container in the prior art, and the container body 1 is provided with an air suction port 2 and a dirt inlet 3. A cyclone separation chamber 11 and a storage chamber 14 are sequentially arranged in the container body 1 from top to bottom, and the intersection of the storage chamber 14 and the cyclone separation chamber 11 forms a first through port 15. The air suction port 2 and the dirt inlet 3 are respectively communicated with the cyclone separation chamber 11. Referring to Figure 2 As shown, in the state that the container body 1 is horizontally tilted, the lowest point of the storage chamber 14 is lower than the lowest point of the first through port 15, and the lowest point of the storage chamber 14 has a certain height difference with the lowest point of the first through port 15, such as that the first through port 15 is eccentric to the storage chamber 14, the storage chamber 14 is conical or the storage chamber 14 has other suitable shapes in the prior art, etc.

[0028] In use, the dirt cleaning device is installed on a corresponding cleaning equipment such as a scrubber, and the suction port 2 is connected with a corresponding suction device such as a suction fan. After the cleaning equipment cleans the ground, sewage mixed with garbage is generated. Under the action of the suction force at the suction port 2, the sewage mixed with garbage enters the cyclone separation chamber 11 from the dirt inlet 3, and then the sewage mixed with garbage and the airflow spirally flow downward into the storage chamber 14. The sewage mixed with garbage is finally separated from the spiral airflow, and the airflow spirally flows from the lower part to the upper part of the storage chamber 14 and the middle part of the cyclone separation chamber 11 in sequence, and finally the airflow flows out of the suction port 2. Through the action of the spiral, the sewage and the garbage are better separated from the airflow, and the sewage and the garbage are not easy to adhere to the inner wall of the container main body. The cleaning of the container main body 1 can be better guaranteed, and the sewage and the garbage are not easy to enter the corresponding suction device or even block the pipeline and damage the equipment. In the state of horizontal tilting of the container main body 1, the lowest point of the storage chamber 14 is lower than the lowest point of the first through port 15, so that when the container main body 1 is tilted or horizontally tilted, the liquid in the storage chamber 14 can be prevented from flowing back, and the safety and reliability are better. Under the premise of meeting other structural performance of the cyclone suction type container main body, the height difference between the lowest point of the storage chamber 14 and the lowest point of the first through port 15 can be as large as possible, and the backflow prevention effect is better.

The connection is more convenient and compact, and the structure is more compact, stable and reliable.

[0031] The bottom of the container body 1 is provided with a sewage outlet 13, which is communicated with the bottom of the storage cavity 14, and the sewage outlet 13 can be connected with a sewage valve 7, which is usually closed, so as to facilitate the periodic discharge of sewage and garbage in the container body 1 according to needs. In addition, under the action of the suction force at the air suction port 2, if clean liquid such as clean water, cleaning liquid and the like enters the cyclone separation cavity 11 from the sewage inlet 3, the clean liquid and the airflow flow spirally downward, so as to clean the container body 1, and then the sewage valve 7 is opened to discharge the liquid in the container body 1, so as to realize the self-cleaning of the inside of the container body 1, which is more simple, convenient, time-saving and labor-saving, and the like.
