The floor mopping machine with the sewage backflow prevention structure in the preferred embodiment of the utility model; as shown in figure 1, the mopping machine comprises a shell 2, a mopping assembly 5 is connected to the lower end of the shell 2, a roller 4 is arranged at the joint of the mopping assembly 5 and the shell 2, and the roller 4 is used for facilitating the forward and backward movement of the mopping machine. The upper end of the shell 2 is connected with a handle 6 through a connecting rod 1, an operator holds the handle 6 to push the mopping machine to move forward or backward, sewage is absorbed under the action of the mopping assembly 5, and then the sewage is sucked into a sewage tank 3 arranged on the shell.

Further, as shown in fig. 2 to 3, the floor mopping assembly 5 includes a bottom case 52, and an upper case 51 disposed above the bottom case, and the floor mopping assembly 5 further includes a rolling brush 54 disposed at front ends of the bottom case and the upper case, and absorbs sewage while cleaning the floor. The contact portion of the drum brush 54 and the bottom case 52 is formed with a water trough 57 on the bottom case 52, and when the drum brush 54 rotates, it contacts the edge of the bottom case 52, and scrapes off the sewage adsorbed on the drum brush 54 by the edge of the bottom case, and then flows into the water trough 57, and the sewage in the water trough 57 is sucked into the sewage tank 3 by the fan 7 provided on the housing 2.

Further, as shown in fig. 2 to 3, the end of the water tank 57 is connected to the sewage tank 3 through a suction pipe 55, and the blower 7 sucks the sewage in the water tank 57 into the sewage tank 3 through the suction pipe. In order to prevent the suction force in the suction pipe 55 from being lost at the moment when the blower stops operating, the sewage remaining in the suction pipe 55 flows back to the water tank 57 and then flows to the ground. The water trough 57 is connected with the suction pipe 55 through a lower connector 56, and the radius of the inner wall 561 of the lower connector 56 close to the suction pipe 55 is smaller than that of the inner wall 553 of the suction pipe, so that a step is formed between the inner wall of the suction pipe and the inner wall of the lower connector. When the fan stops working, the sewage remained in the water suction pipe 55 flows back and then stays in the water suction pipe 55 under the action of the step, so that the sewage is prevented from flowing back into the water tank 57 to pollute the clean ground.

Further, as shown in fig. 2-3, due to the vibration generated when the fan 7 works and the physical vibration generated when the floor mopping machine moves, in order to prevent the lower connector from falling off from the water suction pipe, a top rod 521 is arranged on one side of the lower connector 56 away from the water suction pipe 55, and the top rod 521 is detachably connected with the bottom shell 52, so that the lower connector 56 is pushed in the direction close to the water suction pipe 55, and the connection stability of the lower connector 56 is enhanced.

Further, as shown in fig. 2-4, since the floor mopping machine assembly 5 is horizontally disposed and the housing 2 is disposed approximately vertically, the suction pipe 55 should be bent, in order to avoid breaking or breaking the suction pipe 55, the bent portion 554 thereof is fixed by the crankshaft 551, and both ends of the crankshaft 551 are fixed on the bottom shell 52 by the crankshaft pressing plate 552, so as to enhance the link stability of the suction pipe 55. One end of the water suction pipe 55 connected with the sewage tank 3 is connected through a hose connector 58, and the periphery of the hose connector 58 is connected with a connector rubber coating 59, so that the connection sealing performance of the water suction pipe 55 and the sewage tank 3 is better, and water leakage is avoided.

Further, as shown in fig. 2-3, the upper housing 51 is further provided with an end cover 53 covering the rolling brush 54, the upper end of the rolling brush 54 is covered to prevent the rolling brush 54 from splashing sewage in the rotating process, and the end cover 53 is detachably connected with the upper housing 51.

Further, as shown in fig. 5, the housing 2 comprises an upper housing 21 and a lower housing 22 which are detachably connected, the upper end of the lower housing 22 is connected with the connecting rod 1, the lower end is connected with the floor mopping assembly 5, and a fan 7 for sucking sewage into the sewage tank is further arranged in the lower housing. The upper casing 21 covers the fan 7 and is connected with the lower casing 22, a chamber 211 is arranged on the upper casing 21, and the sewage tank 3 is arranged in the chamber and penetrates through the upper casing 21 to be connected with the suction pipe 55.

Further, as shown in fig. 6, a water conduit 31 is provided in the sewage tank 3, one end of the water conduit 31 is connected to the suction pipe 55, the other end is lower than the uppermost end of the sewage tank, and a water storage tank 32 is formed between the outer wall of the water conduit 31 and the inner wall of the sewage tank 3. After the blower 7 sucks the sewage into the suction pipe 55, the sewage continuously flows back through the water guide pipe 31 and finally flows into the water storage tank 32 for storage, and at this time, the sewage sucking process is finished. When sewage in the water storage tank 32 reaches a certain water level, the sewage tank is detached from the upper shell 21 through the handle 33 arranged on the outer shell of the sewage tank, the sewage tank 3 is clamped and connected with the upper shell through the clamping part 34, the connection mode also facilitates the detachment of the sewage tank 3, and the use is more convenient. In order to facilitate the observation of the water tank of the sewage tank 3, one side of the sewage tank close to the handle adopts a transparent arrangement, which facilitates the observation of the water level of the water storage tank 32.

When the mop is used, an operator holds the handle 6, moves the mop forward or backward under the action of the roller 4, sucks sewage onto the roller 54 by the roller brush 54, scrapes the sewage from the roller 54 into the water trough 57 under the opposite action of the bottom shell 52 on the roller brush 54 when the roller brush 54 rotates, and enables the sewage to enter the water guide pipe 31 after passing through the water suction pipe 55 under the action of the fan 7 and finally flow into the water storage tank 32 for storage. When the blower stops working, a small part of sewage in the suction pipe 55 flows back, and is prevented from flowing into the water trough 57 under the action of the lower connector 56, so that the sewage is prevented from flowing to the ground. When the sewage in the water storage tank 32 is stored to a certain water level, the handle 33 is held by hand to take the sewage tank and the upper shell 21 down, and after the sewage is poured out, the sewage tank is clamped and connected with the upper shell 21 through the clamping part 34 of the sewage tank so as to be used continuously next time.

It is to be understood that the present invention has been described with respect to certain embodiments and that various changes in the features and embodiments, and equivalents thereof, may be resorted to without departing from the spirit and scope of the invention as those skilled in the art readily understand. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the invention without departing from the essential scope thereof. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of the present application are intended to be covered by the present invention.
