The water pump draws water from the water tank and provides it to the roller brush. The brush motor assembly 3-1 provides power to the roller brush assembly 3-2 to clean the floor surface. During cleaning, the front wheel assembly 4-1 and the rear wheel assembly 4-2 are in contact with the surface to be cleaned.

[0060] As shown, Figure 3 The brush housing 3-4-1 is movably mounted on one side of the brush housing 3-4-1 through a fulcrum 6. The brush shaft cover 3-8 is connected to the brush assembly 3-2. When the brush shaft cover 3-8 moves in a circular motion around the fulcrum 6, it drives the brush assembly 3-2 to move.

[0061] The transmission mechanism is used to move the brush shaft cover 3-8 to change the interference between the brush assembly 3-2 and the cleaning surface.

[0062] The transmission mechanism is also used to move the scraper assembly 3-7, which interferes with the brush assembly 3-2 after moving, to change the position of the negative pressure area of the brush assembly 3 during dust collection.

[0063] The brush housing 3-4-1 is provided with a movable fixed pin 3-9 and a reset push rod 3-10. The fixed pin 3-9 is used to move the push rod 3-10. The brush housing 3-4-1 is provided with a transmission mechanism drive motor 3-11. The fixed pin 3-9 is provided on the shaft of the transmission mechanism drive motor 3-11. The fixed pin 3-9 can rotate with the motor shaft by a certain angle.

[0064] As an optional embodiment, as shown in Figure 12 and Figure 14 The brush housing 3-4-1 is provided with a guide groove 3-4-2. The push rod 3-10 is installed in the guide groove 3-4-2 through a compression spring 3-4-3.

The compression spring 3-4-3 is used to reset the push rod 3-10 without external force, making it convenient for next use.

[0065] The push rod 3-10 is connected with the scraping strip assembly 3-7 for interfering with the rolling brush assembly 3-2. The push rod 3-10 is connected with the scraping strip assembly 3-7. Therefore, when the transmission mechanism driving motor 3-11 drives the fixed pin 3-9 to rotate to a certain angle and abuts against the end of the push rod 3-10, the push rod 3-10 moves forward in the guide groove 3-4-2, the push rod 3-10 drives the scraping strip assembly 3-7 to move forward, and the compression spring 3-4-3 installed on the push rod 3-10 can be used to reset the scraping strip assembly 3-7 and the push rod 3-10 after the transmission mechanism driving motor 3-11 rotates.

[0066] As an optional embodiment, as shown in Figures 4-6 The scraping strip assembly 3-7 includes a scraping strip connecting rod 3-7-1, a scraping strip 3-7-2 and a sliding block 3-7-3. The scraping strip 3-7-2 is installed between the scraping strip connecting rod 3-7-1 and the sliding block 3-7-3. The floor brush body 3-4 supports the movement of the sliding block 3-7-3, can keep stable when the scraping strip assembly 3-7 moves, and is beneficial to the realization of the interference of the scraping strip assembly 3-7 to the rolling brush assembly 3-2.

[0067] As an optional embodiment, as shown in Figure 5 and Figure 8 The scraping strip connecting rod 3-7-1 is in a reverse L-shaped structure at one end, and the end is connected with the push rod 3-10. The push rod 3-10 drives the scraping strip connecting rod 3-7-1 to move synchronously. The structure of the scraping strip connecting rod 3-7-1 is simple, and the scraping strip assembly 3-7 can move with the push rod 3-10 on the premise that the scraping strip assembly 3-7 is reliably connected with the push rod 3-10.

[0068] As shown in Figure 11 and Figure 13 The push rod 3-10 is also used for extrusion fitting with the rolling brush shaft cover 3-8. The rolling brush shaft cover 3-8 is arranged on both sides of the floor brush shell 3-4-1. The front end of the rolling brush shaft cover 3-8 is connected with the rolling brush shaft of the rolling brush assembly 3-2, and the rear end is connected with the floor brush shell 3-4-1 through a fulcrum 6. The rolling brush shaft cover 3-8 can rotate at a certain angle along the fulcrum 6. That is, the left and right rolling brush shaft covers 3-8 are connected with the floor brush body 3-4 through the fulcrums 6, can make a circular motion along the fulcrums 6, and realize the up-down displacement of the rolling brush assembly 3-2.

[0069] As an optional embodiment, as shown in Figure 12 and Figure 14As shown, the push rod 3-10 is provided with a boss 3-10-1 at the lower end of one end, the boss 3-10-1 includes a horizontal surface and an inclined surface, and the boss 3-10-1 is used to press the roller brush shaft cover 3-8. The roller brush shaft cover 3-8 is provided with a structure matching the boss 3-10-1, that is, the roller brush shaft cover 3-8 is provided with a matching inclined surface and horizontal surface structure.

[0070] As shown in Figures 11-14 When the push rod 3-10 is driven forward by the fixing pin 3-9, the boss 3-10-1 of the push rod 3-10 and the boss of the roller brush shaft cover 3-8 first move on the plane, and then move on the inclined surface when moving to a certain distance. At this time, the roller brush shaft cover 3-8 will be pushed down, driving the roller brush assembly 3-2 to move downward. After the transmission mechanism drives the motor 3-11 to rotate, the boss 3-10-1 of the push rod 3-10 and the boss of the roller brush shaft cover 3-8 return to the plane, driving the roller brush assembly 3-2 to move upward and reset.

[0071] The movement of the push rod 3-10 drives the movement of the scraping strip assembly 3-7, and the movement of the scraping strip assembly 3-7 interferes with the roller brush assembly 3-2 in the horizontal direction. At the same time, the movement of the push rod 3-10 will interfere with the roller brush assembly 3-2 in the vertical direction, so that the use position of the roller brush assembly 3-2 meets the use requirements.

[0072] When the cleaning object is a carpet cleaning surface 5-2, as shown in Figures 7-8 The carpet mode is opened through the handle assembly 1, the interference distance between the roller brush assembly 3-2 and the carpet surface is A, and the interference distance between the scraping strip assembly 3-7 and the roller brush assembly 3-2 is B. At this time, the scraping strip assembly 3-7 is tangent to the roller brush assembly 3-2. The suction motor assembly 2-2 arranged in the body assembly 2 works at a high gear to generate the maximum negative pressure in the cavity where the roller brush assembly 3-2 is located. The roller brush assembly 3-2 works at a set speed C to clean the carpet surface. This mode can better clean and suck away the fine dust and particles in the carpet, and the cleaning efficiency is higher.

[0073] When the cleaning object is a hard floor cleaning surface 5-1, as shown in Figures 9-10As shown, by opening the hard floor mode through the handle assembly 1, the transmission mechanism drives the motor 3-11 to rotate the rotatable fixed pin 3-9 in the left and right end floor brush assembly 3 to a set angle, the fixed pin 3-9 pushes the push rod 3-10 forward, and in the process of moving forward, the push rod 3-10 drives the roller brush assembly 3-2 to displace downward to a set distance, at this time, the interference distance between the roller brush assembly 3-2 and the hard floor surface is D (D>A), on the other hand, the scraping strip assembly 3-7 is also moved forward to a set distance, at this time, the interference distance between the scraping strip assembly 3-7 and the roller brush assembly 3-2 is E (E>B), and the roller brush assembly 3-2 cleans the hard floor surface at a set speed F (F Figure 15 As shown, the air inlet direction A and the air outlet direction B, the negative pressure area is transferred from the cavity where the roller brush assembly 3-2 is located to the suction port of the floor brush assembly 3, and the cleaning efficiency of the hard floor is higher in this mode.

[0074] The purpose of the embodiment of the present application is to also provide a use method applied to the aforementioned floor cleaning machine, which comprises the following steps:
