[0028] 1.

It is a detachable design for easy cleaning to ensure low resistance and stable blocking effect of the floor brush. When the floor brush moves, the brush can block the hair and dust on the moving path of the first auxiliary wheel. Some of the hair and dust that enter the first cleaning mechanism and contact the first auxiliary wheel can be removed synchronously through the conical scraper and the rolling of the first auxiliary wheel; the second cleaning mechanism is mainly used for the anti-blocking and jamming protection of the spherical second auxiliary wheel. This structure can realize the sweeping of dust and hair on the surface of the second auxiliary wheel and the outside of the first mounting groove when the floor brush moves to prevent them from being embedded between the two, causing the structure to be blocked and jammed, thereby realizing the protection function.

[0030] 3. The linkage block and linkage switch can cooperate with the main switch of the floor brush and vacuum cleaner to form dual switch control. After the main switch is turned on, the floor brush needs to be placed on the surface to be cleaned. At this time, the linkage block is pressed into the second installation groove and triggers the linkage switch to realize the power supply and operation of the electrical components in the vacuum cleaner and floor brush. Otherwise, it is in a power-off state, which makes the floor brush more convenient and energy-saving to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] See also Figure 1-5 The present invention provides a technical solution: a vacuum cleaner floor brush that can be used in a variety of scenarios, including:

[0045] Floor brush body 1;

[0046] Moving wheels 2, which are rotatably connected to both sides of the rear end of the floor brush body 1;

[0047] A first auxiliary wheel 3, which is rotatably disposed in a third mounting groove 21 of the tread of the moving wheel 2 via a rotating shaft 31, and whose side surface extends to the outside of the moving wheel 2;

[0048] The second auxiliary wheel 4 is embedded and rolled in the first mounting groove 11 of the floor brush body 1. The second auxiliary wheel 4 is a spherical structure. The first mounting groove 11 is a spherical groove. A plurality of the third mounting grooves 21 and the rotating shaft 31 are arranged at intervals and tilted on the moving wheel 2 with the ends facing the second auxiliary wheel 4.

[0049] The floor brush of the vacuum cleaner of the present invention moves the floor brush back and forth through the moving wheel 2, on which the first auxiliary wheel 3 is arranged to realize the lateral and arc-shaped movement of the floor brush, and the first auxiliary wheel 3 is arranged obliquely on the moving wheel 2, with its end facing the second auxiliary wheel 4. When the floor brush is cleaning the arc edge of the ground or other objects, the floor brush connecting tube is held and pushed sideways, so that the floor brush rotates with the second auxiliary wheel 4 as the axis. During this period, the direction of the friction force locally applied to the first auxiliary wheel 3 coincides with its tangential direction, so that the first auxiliary wheel 3 can fully rotate without exerting force on the moving wheel, thereby avoiding the shaking of the moving wheel when the floor brush turns. This design improves the steering flexibility of the floor brush, making it more labor-saving and stable to use, and can be applied to the cleaning needs of floor brushes in various scenes and different terrains.

[0050] In one embodiment, a plurality of the first auxiliary wheels 3 are layered along the tread axial direction of the moving wheel 2 and each layer is staggered for arrangement, which is a spindle structure, so that when the moving wheel rotates, the first auxiliary wheel 3 can always contact the surface to be cleaned, ensuring the movement stability.

[0051] like Figure 2 As shown, in another embodiment, the moving wheel 2 is provided with a first cleaning mechanism on the outside of the third mounting groove 21, and the first cleaning mechanism includes a brush assembly 5, and the brush assembly 5 includes an annular bracket and a brush 51 arranged on the outside of the annular bracket, and the annular bracket is sleeved on the outside of the first auxiliary wheel 3, and the side of the first auxiliary wheel 3 extends to the outside of the annular bracket, and the annular bracket is assembled in the slot on the surface of the moving wheel 2 through a clamping block 52. The first cleaning mechanism is mainly used for blocking, isolating and cleaning the hair and dust on the first auxiliary wheel 3 and the surface to be cleaned. It is a detachable design, which is easy to clean, so as to ensure low resistance and stable blocking effect of the floor brush. When the floor brush moves, the brush 51 can block the hair and dust on the moving path of the first auxiliary wheel 3.

[0052] In order to further improve the protection effect of the first cleaning mechanism on the movement of the first auxiliary wheel 3, a conical scraper 53 is arranged on the inner cavity of the annular bracket to extend outward, the conical scraper 53 is attached to the outer side of the first auxiliary wheel 3, and the side of the first auxiliary wheel 3 extends to the outside of the conical scraper 53. When in use, part of the hair and dust that enter the first cleaning mechanism and contact the first auxiliary wheel 3 can be removed synchronously by the conical scraper 53 and the first auxiliary wheel 3 rolling.

[0053] like Figure 3 , 4As shown, in another embodiment, the floor brush body 1 is provided with a second cleaning mechanism on the outside of the second auxiliary wheel 4, the second cleaning mechanism includes a fan assembly 6 and a sealing plate assembly 7, a plurality of purge air ducts 12 extend outward from the surface of the first mounting groove 11, and the ends of the plurality of purge air ducts 12 converge in a pressurized air duct 13, the fan assembly 6 is arranged in the pressurized air duct 13, and the pressurized air duct 13 is connected to the outside.

[0054] The fan assembly 6 is connected to the air pressure monitoring controller 61 .

[0055] The sealing plate assembly 7 is rotatably disposed in the purge air duct 12 through a rotating block 71 at the end, and is used for opening and closing control of the purge air duct 12. The rotating block 71 is rotatably disposed on one side of the purge air duct 12, and an associated structure is disposed on the rotating block 71 and the second auxiliary wheel 4.

[0056] The association structure includes a plurality of first association blocks 41 on the surface of the second auxiliary wheel 4 and a second association block 72 on the rotating block 71 . Both the first association blocks 41 and the second association blocks 72 are magnets.

[0057] A torsion spring is connected between the rotating block 71 and the purge air duct 12, and a sealing strip 73 which is sealed with the outer end of the rotating block 71 is arranged on the other side of the purge air duct 12. The second cleaning mechanism is mainly used for the anti-blocking and jamming protection of the spherical second auxiliary wheel. When the structure is used, after the vacuum cleaner and the floor brush are powered on, the fan assembly 6 starts to operate, pressurizes the gas in the pressurized air duct 13, and the air pressure monitoring controller 61 monitors the internal pressure in real time and automatically controls the fan assembly 6; the floor brush moves, the second auxiliary wheel 4 rolls, and the first associated block 41 on its surface rotates synchronously. When it approaches the sealing plate assembly 7, the sealing plate assembly 7 rotates through the action of magnetic force, and the corresponding purge air duct 12 is connected as a whole, and the pressure difference between the pressurized air duct 13 and the first mounting groove 11 and the purge air duct 12 forms an airflow toward the second auxiliary wheel 4, thereby sweeping the dust and hair on the surface of the second auxiliary wheel 4 and the outside of the first mounting groove 11 to prevent them from being embedded between the two, causing the structure to be blocked and jammed, thereby realizing the protection function.

This design can be used in conjunction with the main switch of the floor brush and the vacuum cleaner to form a dual switch control. After the main switch is turned on, the floor brush needs to be placed on the surface to be cleaned. At this time, the linkage block 8 is pressed into the second mounting groove 14 and the linkage switch 81 is triggered to realize the power supply and operation of the electrical components in the vacuum cleaner and the floor brush. Otherwise, it is in a power-off state, thereby making the floor brush more convenient and energy-saving to use.
