Description

Technical Field

[0001] This invention belongs to the field of cleaning robot technology, and in particular relates to a cleaning robot's sludge extraction and cleaning system. Background Technology

[0002] Currently, the cleaning systems used in cleaning robots on the market mainly employ a mop-washing method. This involves using a high-speed rotating, wet mop to scrub the floor, thus cleaning it. However, this method merely spreads the dirt evenly; it doesn't actually clean it completely.

[0003] For example, Chinese invention patent CN202010643743.6, entitled "A Floor Cleaning Robot and Its Working Control Method," discloses a floor cleaning robot comprising a body, with a mop assembly at the bottom of the body for cleaning the floor, and a mop at the bottom of the mop assembly. The cleaning effect is enhanced by changing the pressure on the mop assembly, but it cannot recover the wastewater from the floor; the wastewater is still spread evenly on the floor by the mop, and the cleanliness of the mop itself decreases with increasing cleaning time, resulting in a gradual decline in cleaning effectiveness. Furthermore, the mop itself cannot be completely cleaned, and after a period of use, the cleaning effect will significantly decrease, requiring replacement. Summary of the Invention

[0004] The purpose of this invention is to provide a cleaning robot system that uses water to mop the floor while simultaneously using positive and negative pressure air circulation to effectively remove dirt from the floor, thus solving the problems raised in the prior art.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0006] This invention relates to a cleaning robot's cleaning system, comprising a robot housing and a water pump. The bottom side of the robot housing has a cleaning area, and the cleaning area is provided with a suction port connected to the water pump. During operation, the water pump draws dirt from the ground into the suction port.

[0007] Furthermore, a fan is also provided on the robot housing, and an air inlet is provided on the bottom side of the robot housing located inside the cleaning area; when in use, the fan is started, and under the action of negative air pressure, the dirt on the ground is blown to the area near the suction port; an air outlet is also provided on the bottom side of the robot housing located on the opposite side of the air inlet.

[0008] Furthermore, the robot housing includes an upper air duct assembly and a lower air duct assembly that are assembled together; the upper air duct assembly includes an air duct mounting base, and a fan and air duct installed on the air duct mounting base; the lower air duct assembly includes a movable air duct mounting base and a movable air duct installed on the movable air duct mounting base.

[0009] Furthermore, the cleaning area includes an annular soft rubber scraper disposed on the outer bottom side of the mobile air duct mounting base, and both the air inlet and the air outlet are disposed within the inner area of ​​the annular soft rubber scraper.

[0010] Furthermore, the fan is connected to the air inlet and air outlet in sequence through the air duct and the movable air duct.

[0011] Furthermore, a water pump is installed in the space formed by the upper and lower air duct units.

[0012] Furthermore, the inner region of the annular soft rubber scraper is also provided with a rotating scraper assembly A in a first rotation direction and two rotating scraper assemblies B in a second rotation direction; wherein the rotating scraper assembly B and the rotating scraper assembly A rotate in opposite directions.

[0013] Furthermore, a rear soft rubber scraper is provided on the bottom side of the robot housing, located behind the moving path of the annular soft rubber scraper, along the walking direction of the robot housing.

[0014] The present invention has the following beneficial effects:

[0015] This invention is a cleaning system that uses water to mop the floor while simultaneously using positive and negative pressure air circulation to thoroughly clean the dirt on the floor. This avoids the problem of the mop not being able to clean the floor completely, and the cleaning effect declining significantly with the increase of usage time.

[0016] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0024] like Figure 1 A cleaning robot's cleaning system includes a robot housing and a water pump 12. The water pump 12 is connected to a suction port located on the bottom side of the robot housing. When working, the water pump draws dirt from the ground into the suction port. The bottom side of the robot housing is a cleaning area.

[0025] like Figure 2 Building upon the above, to better clean stains, a fan 1 is installed on the robot's casing, with an air inlet 101 near the suction port and an air outlet 102 on the side furthest from the suction port. During operation, when the fan 1 is activated, the negative air pressure blows the stains on the ground towards the area near the suction port. Through the combined action of the water pump 12 and the fan 1, the cleaning method for the ground is optimized. The flowing water process collects and recovers dirt from the ground, and the positive and negative pressure circulation mode significantly improves the cleaning efficiency and dirt recovery rate.

[0026] like Figure 1-3 In this invention, the robot housing includes an upper air duct assembly 6 and a lower air duct assembly 7 that are assembled together. The upper air duct assembly 6 includes an air duct fixing seat 3, and a fan 1 and an air duct 2 installed on the air duct fixing seat 3. The lower air duct assembly 7 includes a movable air duct mounting seat 5 and a movable air duct 4 installed on the movable air duct mounting seat 5. The fan 1 is connected to the air inlet 101 and the air outlet 102 in sequence through the air duct 2 and the movable air duct 4.

[0027] Meanwhile, the water pump 12 is installed in the space formed by the upper air duct assembly 6 and the lower air duct assembly 7.

[0028] The upper assembly 6 and the lower assembly 7 of the air duct can move up and down through a flexible connection, allowing gas to pass through.

[0029] like Figure 1-4 Based on the above, the cleaning area includes an annular soft rubber scraper 10 located on the outer bottom side of the mobile air duct mounting base 5, with both the air inlet 101 and the air outlet 102 located within the annular soft rubber scraper 10. Simultaneously, within the annular soft rubber scraper 10, there is a clockwise rotating scraper assembly A8 and two counterclockwise rotating scraper assemblies B9. A rear soft rubber scraper 11 is located on the bottom side of the robot housing, behind the annular soft rubber scraper 10, along the robot housing's walking direction. During use, the rotating scraper assembly A8 and the rotating scraper assembly B9 rotate at high speed under motor drive, and the rapid rotation of the scraper against the ground achieves a quick cleaning effect. Simultaneously, under the centrifugal force of the high-speed rotation, water inside the annular soft rubber scraper 10 is flung out, and dirt on the ground is accelerated into the wastewater tank by the positive and negative pressure airflow. Meanwhile, if the front ring-shaped soft rubber squeegee does not wipe the water off the ground, the soft rubber squeegee 11 will leave the dirt in the cleaning area to ensure that it enters the cleaning cycle driven by the positive and negative pressure air flow.

[0030] In summary, the cleaning mechanism of the cleaning robot of the present invention consists of three rotating scrapers, a front annular soft rubber scraper 10, and a rear soft rubber scraper 11. It uses the rubber scraper on the high-speed rotating scraper and the front and rear soft rubber scrapers to clean the ground. Compared with the traditional method of cleaning with a mop, the scraper does not need to be replaced as the usage time increases, avoiding the expense of users to replace consumables. At the same time, its cleaning effect does not decrease with the increase of time.
