As shown in Fig. 1-Fig. 4, the present invention provides an embodiment of a mop-sweeping integrated cleaning tool.

The mopping and sweeping integrated cleaning tool includes a cleaning roller 2 that rotates during cleaning and a cleaning chamber A on the surface of the cleaning roller 2. The cleaning chamber A communicates with a clean water tank (not shown in the drawings) and a dirty water tank (not shown in the drawings) respectively. , Between the cleaning chamber A and the clean water tank, there is a first water pump (not shown in the accompanying drawings) that intermittently pumps clean water into the cleaning chamber.

Specifically, the mopping and sweeping integrated cleaning tool 1 is powered by a power source, such as a battery or commercial power. The cleaning roller 2 is directly or indirectly driven by a roller motor (not shown in the drawings). The cleaning chamber A is surrounded by the water squeezing bar 4, the water pressing bar 3 and the surface of the cleaning roller 2 to form a strip-shaped cavity. The cleaning chamber A is arranged parallel or non-parallel to the rotation axis of the cleaning cylinder 2 . When non-parallel arrangement, described cleaning chamber A forms an included angle with cleaning roller 2 rotating shafts, and this included angle can be set to 5-30 degree, like this, when clear water flushes the surface of the higher side of cleaning roller 2, sewage can Utilize gravity to quickly flow to the lower side, reducing the contact time between the sewage and the surface of the cleaning drum 2 . The cleaning chamber A is provided with nozzles 8 for spraying clean water on the surface of the cleaning cylinder 2 .

When in use, the first water pump injects clean water into the clean water chamber in an intermittent manner or directly sprays clean water on the surface of the cleaning roller 2, and washes the surface of the cleaning roller through a certain flow rate of clean water to realize cleaning. Water injection, during the cleaning process, there will not be too much sewage or clean water in the cleaning chamber A, which can avoid the resistance of the remaining water to the clean water when the clean water is injected, resulting in a decrease in the flow rate of the injected clean water, thereby affecting the cleaning effect of the cleaning cylinder. At the same time, the use of intermittent injection of clean water can prolong the use time of clean water, avoiding the need to add clean water multiple times during the cleaning process, thereby affecting the user experience.

According to requirements, the mopping-sweeping integrated cleaning tool includes a first control circuit for controlling the continuous rotation of the cleaning roller 2 and a second control circuit for controlling the first water pump to work in pulses or intermittently. In order to improve the cleaning effect of the cleaning cylinder, the clear water emission direction of the nozzle 8 is tangent to the surface of the cleaning cylinder 2, that is, the clean water emission direction is from top to bottom and tangent to the surface of the cleaning cylinder 2, so that the clear water of the nozzle 8 can be effectively generated. The active force is applied to the stubborn garbage on the surface of the cleaning cylinder 2, thereby improving the cleaning effect. In order to improve the cleaning efficiency of the cleaning roller 2 and expand the cleaning area, the nozzle 8 is provided with a strip-shaped water outlet (not shown in the drawings), which is parallel to the cleaning roller.

In order to avoid the impact of the cleaned garbage on the subsequent cleaning, the nozzle 8 is offset to the direction of the water flow, which can provide power for the sewage flow, so that the sewage in the cleaning chamber can be quickly discharged, and the sewage can be prevented from infiltrating into the cleaning drum due to long-term contact , affect the cleaning effect. The first water pump flushes the surface of the cleaning roller 2 with clear water through the moving nozzle mechanism,

According to needs, the mopping and sweeping integrated cleaning tool also includes a sewage tank (not shown in the drawings) connected to the cleaning chamber A, which can realize continuous cleaning of garbage for a long time. In order to reduce the sewage retention time in the cleaning chamber, between the cleaning chamber A and the sewage tank (not shown in the drawings), there is a time delay after the first water pump intermittently outputs clear water to the surface of the cleaning roller to flow through the surface of the cleaning roller. Sewage is injected into the second water pump (not shown in the drawings) of the sewage tank. The second water pump works asynchronously with the first water pump, and the second water pump will start to work only after the sewage is collected, so as to suck the sewage into the sewage tank. This can reduce the useless work of the second water pump on the one hand, and on the other hand, when the sewage is less, there is air when the second water pump is turned on when the drain is not submerged by sewage, which will generate noise.

When in use, the cleaning roller 2 rotates directly or indirectly driven by the motor, and the cleaning roller 2 is in contact with the cleaning surface for cleaning. As the cleaning roller 2 rotates, the cleaning roller 2 in contact with the cleaning rotates to squeeze the water bar 3 and press The area between the water strips 4 becomes a part of the cleaning chamber A. The surface of the cleaning roller 2 is flushed with clean water intermittently or in pulses by properly controlling the moving nozzle mechanism. The moving nozzle mechanism moves continuously so that the nozzle always moves back and forth along the axis of the cleaning roller 2. Move, that is, move left and right along the reciprocating shaft 9, so that intermittent or pulsed flushing can be formed on the surface of the cleaning cylinder 2, and the moving nozzle mechanism cooperates so that the flushing position is different each time, so that the least amount of water and the least nozzles are used. , to achieve multi-point cleaning, thereby improving the uniformity of cleaning. In the case of limited water, the continuous use time can be extended by adding water once, which is convenient to use and simple in structure.

As shown in FIG. 4 and FIG. 5 , the pressurized water strip 3 includes a water collecting structure for collecting the liquid flowing through the surface of the cleaning cylinder. The water collecting structure includes a water collecting groove 31 far away from the surface of the cleaning roller. The lowest part of the water collecting tank 31 is provided with a water collecting port 32, and the water collecting port 32 communicates with the sewage tank.

According to needs, in order to gather the sewage quickly, the bottom surface of the sump 31 is one or two slopes 30, the slope 30 can quickly gather the sewage, and a water collection port 32 is provided at the lowest point of the slope, and the water collection port 32 is connected with the waste water tank. (not shown in the drawings), so that the sewage can be better collected and discharged. In order to avoid the impact of the cleaned garbage on the subsequent cleaning, the spraying direction of the nozzle 8 is offset to the direction of the sewage flow, which can provide power for the sewage flow, so that the sewage in the sump 31 can be quickly discharged, and the sewage can be avoided for a long time. Cleaning the inside of the drum affects the cleaning effect. The first water pump flushes the surface of the cleaning cylinder 2 with clear water through the moving nozzle mechanism.

The present invention provides a control method for a mopping and sweeping integrated cleaning tool. The control method uses a water pump to flush clean water to the surface of the cleaning roller to form a cleaning water flow, including controlling the first water pump to intermittently output clean water to the surface of the cleaning roller to form an intermittent cleaning water flow in the cleaning chamber. .

Specifically, before the first water pump is controlled to intermittently output clean water to the surface of the cleaning roller 2, the cleaning roller 2 is continuously rotated, so that the surface of the cleaning roller 2 is kept at a certain humidity. After the first water pump intermittently outputs clean water to the surface of the cleaning drum 2, the second water pump is started to clean the sewage into the sewage tank after a delay. That is, the second water pump and the first water pump in the above embodiment work asynchronously, and the second water pump will start to work only when the sewage collects to suck the sewage into the sewage tank. This can reduce the useless work of the second water pump on the one hand, and on the other hand, when the sewage is less, there is air when the second water pump is turned on when the drain is not submerged by sewage, which will generate noise.

Above embodiment is only in order to illustrate technical scheme of the present invention, and is not limited to; Although the present invention has been described in detail with reference to foregoing embodiment, those of ordinary skill in the art should understand: it still can be to foregoing each The technical solutions described in the embodiments are modified, or some of the technical features are equivalently replaced, and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
