As the pace of modern life is getting faster and faster, people's work pressure is increasing day by day, and the phenomenon of leaving early and returning late frequently occurs. People rarely have time to clean up household hygiene, such as floor cleaning, so there are many floor cleaning equipment on the market, such as smart washing machines, floor washing machines, etc., for household hygiene.

Due to advances in technology, the use of automated cleaning machines for floor cleaning in indoor environments is a common prior art.

In the existing mopping machine/sweeping machine solution, the clean water tank is filled with clean water under normal circumstances. When the machine is working, the electromagnetic pump receives a signal to perform an operation, and pumps clean water from the clean water tank to the mopping roller brush or brush plate. To wet the cloth above, the wet cloth is driven by the roller brush or brush disc to wipe the ground.

One of the shortcomings of the existing technology is that the existing household smart mopping machines show more than clean and thorough washing, but more like mopping and mopping, and the trajectory of the washing machine running on the ground will leave wet imprint. Because the existing floor washing machine does not realize the recovery of sewage from clean water, that is, it cannot take away the sewage generated after washing the floor, so the effect of cleaning the floor is not good, and the rag will be more dirty, which is obviously not what the user wants. .

Because the cleaning method is changed from rotation to horizontal movement, there will be no winding; Dry brush roller group, clean the brush roller group to complete the wet cleaning of the surface to be cleaned, dry the brush roller group and then dry the cleaned surface; compared with the method of sticking the rag on the machine chassis and the disk brush, the sewage is continuously cleaned while cleaning. Discharge to maintain the cleanliness of cleaning without human intervention; Sewage recovery method: The cleaning brush roller set is composed of at least one brush roller, which takes the water attached to the cleaned surface away from the cleaned surface through centrifugal force when it rotates. Throw the sewage to the catchment plate. The water collecting plate is installed on the top or side of the cleaning and drying brush roller group, the water droplets hit the water collecting plate, the water collecting plate collects the water droplets, and the collected water is sucked away by the water pump through the pipeline.

However, the inventive design of CN204644932U cannot provide clean water source through the model itself and recycle sewage after cleaning. Moreover, the overall design and structure of this integrated cleaning, vacuuming, scrubbing and washing machine is complex, and the dehydration effect is not good, which is limited by the size of the model, the rotational speed of the rollers, and the amount of sewage dehydration.

Existing smart home washing machines cannot achieve more convenient functions, especially, for example, cannot realize self-contained clean water for washing the floor, and self-contained dirt tank to recycle sewage, and at the same time ensure sewage recycling and not easy to leak.

Therefore, in the prior art, there is a need for a floor scrubber that can perform efficient floor cleaning, sewage recovery and water tank replacement in a simple, cost-effective and convenient manner.

In addition, compared with the prior art, it is ideal to provide a more compact and practical front collision detection and reset mechanism for a sweeper/scrubber.

Efficiency (because there is no need for additional pre-processes or interruptions in the normal scrubbing process), while also reducing or even eliminating manual intervention during scrubber operation, which can better share the family's worries.

Scrubbing and sewage recycling mechanism and operation of the washing machine

As shown in FIG. 5 , it shows the water circuit setting and washing sewage recovery of the intelligent washing machine according to an exemplary embodiment of the present invention.

During the operation of the intelligent washing machine, the clean water in the clean water tank 3 flows out from the water outlet 31 of the clean water tank 3, flows from the water inlet 61 of the electromagnetic pump 6 into the water pump 6 (such as the electromagnetic pump 6) through the hose, and then flows through the electromagnetic pump 6. The water outlet 62 flows out, then it is connected to the water spraying part 7 through the hose and sprinkles/flows to the scrubbing roller brush 5, thereby moistening the roller brush 5, making it roll with the scrubber, and scrubbing the ground with clean water and/or mopping.

The sewage generated by wiping/mopping is rotated and thrown away from the scrubbing roller 5 along the tangential direction of the circular cross-section of the scrubbing roller brush 5 due to centrifugal action, and is thrown toward the shield 8 (as shown in FIG. 6 , This example is a transparent shield for easy observation and maintenance), and is thrown into the sewage recovery channel 42 at a position near the A zone (shown in FIG. 6 ), and further enters the sewage recovery channel 42 with the assistance of suction. During this period, the dirt on the ground (including sewage and possible garbage, etc.), if any, also enters the sewage through the sewage recovery port 41 and the sewage recovery channel 42 of the sewage box 4 through the suction effect of wind. in box 4. In the mixed air flow entering the dirt box 4, the dirt contained or entrained therein, including sewage and various solid wastes, etc., can be blocked by the water baffle 22 at the entrance of the air flow passage 21 of the fan and fall into the dirt. In the box 4, the air flow enters the fan 2 through the fan air flow channel 21 and is discharged.

In this way, through the above description, those of ordinary skill in the art can understand and realize that the smart floor washing machine of the present invention has its own clean water tank 3 and a dirt tank 4 and uses the above configuration, structure and arrangement of water outlet, recovery flow path, etc. or its equivalent implementation for brushing/washing operations, can achieve a qualitative leap from "mopping" to "scrubbing" cleaning methods.

Further, as shown in FIG. 6 , it shows a schematic structural diagram of the washing sewage recovery part of the intelligent washing machine according to an exemplary embodiment of the present invention. Among them, the water outlet 31 of the clean water tank 3 is connected with a hose to a water pump, for example, the water inlet 61 of the electromagnetic pump 6, and then the water outlet 62 of the electromagnetic pump 6 is connected with a hose to the sprinkler 7, and thus is supplied to The scrubbing roller 5 is used for the purpose of helping to clean the ground.

According to a preferred example, the scrubbing roller brush 5 can be composed of soft bristles and hard glue, and is driven by the roller brush motor 51 to rotate in a clockwise direction, for example. According to an example, the upper peripheral portion of the scrubbing roller brush 5 is provided with a transparent shield 8 to cover it, and the uncovered part of the lower half is close to the ground to achieve the purpose of cleaning. Among them, the correspondingly arranged area A (in the embodiment shown in FIG. 6 , for example, can be located on the lower left side of the roller brush 5 ) near the side of the sewage recovery port 41 is set so that the scrubbing roller brush 5 and the outer protection There is a larger gap between the hoods 8, which is convenient for the airflow to flow in and bring in sewage. On the other side opposite to it, that is, as shown in the figure at the B area on the lower right side of the roller brush 5, it can be set so that the gap between the scrubbing roller brush 5 and the peripheral shield 8 is smaller This makes it difficult for the suction air to pass through, so as to ensure that the area A has sufficient suction wind, which is used to help suction and entrain sewage into the sewage recovery channel 42 .

During the normal working process of the intelligent floor washing machine of an exemplary embodiment of the present invention, the clean water from the clean water tank 3 is led to the roller brush 5 for sprinkling and wetting, and the wetted roller brush part is rolled and cleaned (by means of brushing). and/or scrubbing action) on the ground, and then roll back to the vicinity of the sewage recovery port 41. At this time, the sewage that has been cleaned on the ground in the rolling brush part will be thrown out by means of centrifugal action, and at the same time, the negative pressure generated by the action of the fan 2 The air flow will bring the water thrown out by the scrubber brush 5 (together with other dirt on the ground, if any) into the sewage recovery channel 42 and into the dirt box 4 . In this regard, the intelligent floor washing machine of the present invention can not only have the effect of cleaning the floor and recycle the sewage, but also can simultaneously have the effect of vacuuming/sucking the solid dirt in the part to achieve the effect of cleaning the floor.

In order to avoid as much as possible that moisture and possible other solid dirt will enter the fan 2 and affect the normal operation of the fan 2, a water baffle 22 can be added between the fan air passage 21 connecting the fan 2 and the dirt box 4, and the water baffle 22 can be set On the side of the fan airflow channel 21 close to the dirt box 4 . Further, according to an example, a sponge 23 may be provided at one end of the airflow channel 21 of the fan close to the water blocking plate 22 . Of course, those of ordinary skill in the art can fully understand and realize that other types of air filtration-water absorbing devices can be provided instead of or in addition to the sponge 23, such as filter elements of suitable specifications, filter screens, and the like.

By letting the smart washing machine have its own clean water tank 3 and dirt tank 4, and using the above flow path setting and the principle of the combination of suction + centrifugation to recycle sewage, the effect of clean water scrubbing and dirt recovery is realized and greatly improved. and cleaning efficiency, greatly reducing or even eliminating manual intervention during work, thus achieving a qualitative leap from "mopping the floor" to intelligent autonomous "scrubbing".

As shown in FIG. 10 , the Hall sensor 16 is installed on the middle case 13 at the position shown in the figure, and the magnet 15 is installed on the bumper 11 at the position shown in the figure. When the bumper and bumper 11 bottom plate are touched or hit by a strong enough force, the magnet and the rubber column will be pushed, and the Hall sensor will receive the signal triggered by the magnetic field and feed it back to the central control system. The rubber column is also deformed by being pushed to produce a rebound force (collision buffering and subsequent rebound reset). At this time, the intelligent washing machine will make a judgment and execute the operation, and the safety lever and the magnet 15 will be reset due to the rebound force.

In an alternative embodiment, the post type rubber can be changed to a flat type, strip type or cable type rubber piece, that is, the rubber piece is made into a flat, long strip or thin wire shape, similar to the one used on a bow and arrow. The string is pushed by the prestressed elastic force to generate the rebound force.

As shown in FIG. 11 , it shows a schematic diagram of a front-impact Hall-type detection structure with flat rubber parts of an intelligent floor scrubber according to an exemplary embodiment of the present invention. In this embodiment, the bumper 11 and the bumper bottom plate 12 are locked together as a movable part, and the two ends of the flat rubber part are connected with the middle shell 13 by pre-tensioning (similar to the string on a bow and arrow), The Hall sensor 16 is mounted on the middle case 13 as shown in FIG. 11 , and the magnet 15 is mounted on the bumper 11 as shown in the drawing.
