[0007] The buffer adjustment assembly includes a limiting slide rod fixedly installed on the inner wall of the mounting cover, a movable plate slidably connected to the surface of the limiting slide rod, and a clamping spring sleeved on the surface of the limiting slide rod. The top and bottom ends of the clamping spring are respectively clamped to the inner top wall of the mounting cover and the upper surface of the movable plate. A connecting plate is fixedly installed on the upper surface of the movable plate, and a tension spring is fixedly installed on the surface of the connecting plate.

[0008] As a further description of the above technical solution: a dust collection box is fixedly installed on the top of the mounting cover, and the dust outlet end of the suction pipe is connected to the inner cavity of the dust collection box through a flexible hose. A negative pressure pump for drawing negative pressure from the inside of the dust collection box is provided on the top of the dust collection box. By drawing negative pressure from the inside of the dust collection box through the negative pressure pump, the negative pressure is transmitted to the suction port, which can suck the garbage into the dust collection box and achieve the purpose of garbage collection.

[0009] As a further description of the above technical solution: the air inlet of the negative pressure pump extends to the inner top of the dust collection box and is equipped with a dust filter; by setting the dust filter, it is possible to prevent garbage from entering the interior of the negative pressure pump, thereby achieving the purpose of safety protection for the negative pressure pump.

[0013] As a further description of the above technical solution: a push handle is welded to the top of the frame, and a mobile power supply and a controller are respectively provided on the surface of the push handle.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. Compared with existing technologies, the adjustment mechanism of this floor cleaning machine, during use, by setting up a buffer adjustment component, utilizes a movable plate slidably mounted on the surface of the limit slide rod, and drives the movable plate downward through a clamping spring, which can make the sweeping roller press against the ground, ensuring the friction effect between the sweeping roller and the ground. In the event of a rigid collision between the sweeping roller and an external object, the movable plate can move upward to avoid the collision, achieving a buffering effect in the vertical direction. Furthermore, since the suction pipe and the movable plate are rotatably connected, when a rigid collision occurs at a position where the sweeping roller is off-center, the fixed plate and the sweeping roller can be twisted to avoid the rigid collision, thereby improving the overall applicability of the floor cleaning machine and ensuring that the floor cleaning machine can be used safely for a long time.

[0016] 2. Compared with existing technologies, the adjustment mechanism of this floor cleaning machine uses a push handle to push the frame and uses moving wheels to support the frame in a rolling motion. During movement, the drive motor drives the sweeping rollers to sweep the ground. A negative pressure pump draws negative pressure from inside the dust collection box, which is then transmitted to the suction port to suck up the garbage into the dust collection box, achieving the purpose of garbage collection. By setting a dust filter, garbage can be prevented from entering the negative pressure pump, achieving the purpose of safety protection for the negative pressure pump. By setting a protective box, the drive motor can be protected to prevent damage from collisions with external objects. By setting four limit slide bars, the stability of the movable plate during lifting and moving can be ensured. Attached Figure Description

[0025] A dust collection box 13 is fixedly installed on the top of the mounting cover 4. The dust outlet end of the suction pipe 5 is connected to the inner cavity of the dust collection box 13 through a flexible hose. A negative pressure pump 14 for drawing negative pressure from the inside of the dust collection box 13 is provided on the top of the dust collection box 13.

[0026] The adjustment mechanism of this ground cleaning machine allows the operator to push the handle 20 to push the frame 2, and the moving wheels 3 provide rolling support for the frame 2. The negative pressure pump 14 draws negative pressure into the dust collection box 13, and the negative pressure is transmitted to the suction port 6, which can suck the garbage into the dust collection box 13 to achieve the purpose of garbage collection.

[0027] The air inlet of the negative pressure pump 14 extends to the inner top of the dust collection box 13 and is equipped with a dust filter 15.

[0028] By setting up a dust filter 15, it is possible to prevent garbage from entering the interior of the negative pressure pump 14, thereby achieving the purpose of protecting the negative pressure pump 14.

[0029] The surface of the suction pipe 5 is provided with a movable plate 7 and a fixed plate 8 from top to bottom. The suction pipe 5 and the movable plate 7 are rotatably connected, and the suction pipe 5 and the fixed plate 8 are fixedly connected. The bottom end of the fixed plate 8 is provided with a cleaning component corresponding to the suction port 6.

[0030] The cleaning assembly includes two side plates 16 fixedly installed on the front and rear sides of the lower surface of the fixed plate 8.

The output shaft of the drive motor 18 is connected to the cleaning roller 17 for transmission.

[0031] It is worth noting that during the movement of the frame 2, the sweeping roller 17 is driven to rotate by the drive motor 18, which can sweep the ground and gather the garbage for the suction port 6 to draw and collect the dust, thereby improving the cleaning effect.

[0032] A protective box 19 is fixedly installed on the surface of the side plate 16, and the protective box 19 covers the surface of the drive motor 18 and the gear.

In addition, when a rigid collision occurs between the cleaning roller 17 and an external object, the movable plate 7 can move upward to move the cleaning roller 17 upward to avoid it, achieving the effect of vertical avoidance and buffering.

[0037] Furthermore, since the suction pipe 5 and the movable plate 7 are rotatably connected, when the cleaning roller 17 is off-center and undergoes a rigid collision, the fixed plate 8 and the cleaning roller 17 can be twisted to avoid the rigid collision, thereby improving the overall applicability of the floor cleaning machine and ensuring that the floor cleaning machine can be used safely for a long time.

[0038] There are four limiting slide rods 9, which are arranged in a rectangular array on the inner wall of the mounting cover 4.
