[0024] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0025] Example 1: Reference Figures 1-12A height-adjustable roller-brush vacuum cleaner comprises: a main unit assembly 1, a floor brush assembly 2, a connector 3, and an adjustment mechanism. The main unit assembly 1 is rotatably mounted on the floor brush assembly 2 via the connector 3. The structures of the main unit assembly 1, floor brush assembly 2, connector 3, and the operating principle of the vacuum cleaner are all prior art. The floor brush assembly 2 comprises a housing 4, a roller brush, and a roller 5. The roller brush is rotatably mounted within the housing 4 and is used to clean impurities on the floor or carpet. The working principle of how the roller brush cleans impurities is also prior art. The roller 5 is used to assist the movement of the vacuum cleaner. The housing 4 can rotate relative to the roller 5. The adjustment mechanism is mounted on the housing 4 and is used to adjust the height of the housing 4 relative to the roller 5. An auxiliary support member 6 is disposed at the bottom of the housing 4, wherein one end of the auxiliary support member 6 abuts the ground.

[0026] The auxiliary support member 6 includes a rotating rod 25, a support plate 26, a pin 27, an auxiliary wheel 28, a first limit plate 29, a second limit plate 30, a third limit plate 31, and a limit slot 32; the rotating rod 25 is rotatably arranged at the lower end of the shell 4, the support plate 26 is fixed on the rotating rod 25, the pin 27 is fixed on the support plate 26, the auxiliary wheel 28 is rotatably arranged on the pin 27, one end of the auxiliary wheel 28 abuts against the ground, one end of the adjusting rod 9 is fixedly connected to the support plate 26, the first limit plate 29 is fixed on the support plate 26, and the second limit plate 30 is fixed at the bottom of the shell 4. When the brush assembly 2 is adjusted to the highest position, the first limit plate 29 will abut against the second limit plate 30, and the third limit plate 31 is fixed on the support plate 26. A limit slot 32 for inserting the third limit plate 31 is provided on the shell 4. The auxiliary wheels 28 and rollers 5 facilitate the movement of the vacuum cleaner on the carpet and provide support for the floor brush assembly 2. The first and second limiting plates 29 and 30 limit the highest position of the floor brush assembly 2. The third limiting plate 31 limits the horizontal position of the floor brush assembly 2.

[0027] The adjustment mechanism includes a knob 7 and a connecting column 8; a through hole 10 is provided on the housing 4, the connecting column 8 can rotate relative to the through hole 10, the knob 7 is fixed on the connecting column 8, the connecting column 8 is movable through the through hole 10, and one end is fixedly connected to the knob 7.

[0028] Example 2: Reference Figures 3-9 , A plurality of grooves 11 are provided on the side wall of one end of the connecting column 8, and one end of the adjusting rod 9 is inserted into the inner wall of the groove 11. The depths of the grooves 11 of the support stem are different. In order to facilitate usage habits, the depths between adjacent grooves 11 are gradually increased or decreased; the adjustment height range a of the floor brush assembly 2 relative to the roller 5 is 3.5-13.5mm, among which the height difference between ceramic tiles and wooden floors is 7.0mm; the height difference of short carpets is 3.5mm; the height difference of medium carpets is 10.0mm; and the height difference of long carpets is 13.5mm. By turning the knob 7, the connecting column 8 is driven to rotate, so that the adjusting rod 9 switches positions in the grooves 11 of different depths. Since the auxiliary support member 6 abuts against the ground or carpet, the thrust is reversed, so that the connecting column 8 drives the shell 4 to move upward together, and the shell 4 rotates relative to the roller 5, thereby adjusting the height of the shell 4 so that the shell 4 can be adjusted according to the height of the carpets of different heights, making it easier for the vacuum cleaner and the roller 5 to work on the carpet, thereby reducing physical effort, improving work efficiency, and improving the cleanliness of the carpet.

[0029] The cross section of the adjusting rod 9 gradually decreases from one end to the other end, or the adjusting rod 9 adopts a tapered structure.

[0030] The adjustment mechanism also includes a fixing plate 12, a shift rod 13, and a shift slot 14. The fixing plate 12 is fixedly mounted within the housing 4, and the shift rod 13 is fixedly mounted on the fixing plate 12. The outer wall of the connecting column 8 is provided with a plurality of shift slots 14 that cooperate with the shift rods 13. The shift rod 13 has a certain degree of elasticity. The number of shift slots 14 is the same as the number of grooves 11, and each shift slot 14 corresponds to a groove 11 of a different depth. By turning the knob 7, the shift rod 13 is inserted into the shift slot 14. The shift rod 13 is positioned in different shift slots 14 according to the required height, thereby changing the fit between the grooves 11 of different depths and the adjustment rod 9.

[0031] The adjustment mechanism also includes a fixing ring 15, a limiting ring 16, a first limiting block 17, a second limiting block 18, and a stopper 19. The fixing ring 15 is fixedly arranged in the housing 4, the limiting ring 16 is fixedly arranged in the fixing ring 15, the connecting column 8 movably passes through the limiting ring 16, the first limiting block 17 and the second limiting block 18 are respectively fixedly arranged on the outer wall of the connecting column 8, one end of the fixing plate 12 is fixedly connected to the fixing ring 15, and the stopper 19 is fixedly arranged on the fixing plate 12. Among them, one end of the first limiting block 17 and the second limiting block 18 respectively abuts the end wall of the limiting ring 16 to prevent the limiting column 8 from escaping from the limiting ring 16. The stopper 19 is located between the first limiting block 17 and the second limiting block 18 and abuts against the first limiting block 17 or the second limiting block 18 in the maximum height and minimum height states respectively, thereby limiting the maximum height or minimum height of the torsional force of the knob 7.

[0032] Limit ring 16 defines a first clearance groove 20 for the first limit block 17 to pass through, and a second clearance groove 21 for the second limit block 18 to pass through. To remove or repair knob 7, knob 7 is rotated so that first limit block 17 and second limit block 18 are located in first and second clearance grooves 20 and 21, respectively, thereby releasing the restraint on connecting post 8 and allowing knob 7 to be removed from through hole 10.

[0033] The adjustment mechanism also includes a first connecting ring 22, a second connecting ring 23, and a third connecting ring 24; the first connecting ring 22, the second connecting ring 23, and the third connecting ring 24 are respectively fixed on the outer wall of the connecting column 8, and the first connecting ring 22, the second connecting ring 23, and the third connecting ring 24 are arranged in order from low to high. The inner diameter of the through hole 10 is larger than the outer diameter of the fixing ring 15, the inner diameter of the fixing ring 15 is larger than the outer diameter of the limiting ring 16, the inner diameter of the limiting ring 16 is larger than the outer diameter of the connecting column 8, the outer diameter of the limiting ring 16 is smaller than the outer diameter of the first connecting ring 22, the outer diameter of the first connecting ring 22 is smaller than the inner diameter of the second connecting ring 23, and the outer diameter of the second connecting ring 23 is smaller than the inner diameter of the third connecting ring 24. As a result, one end of the first connecting ring 22 abuts against the end wall of the limiting ring 16, one end of the second connecting ring 23 abuts against the end wall of the fixing ring 15, and one end of the third connecting ring 24 abuts against the end wall of the through hole 10. This limits one end of the connecting column 8.

[0034] Example 3: Reference Figures 10-11 , The adjustment mechanism includes an intermediate plate 35 fixedly connected to the upper end of the support plate 26 , and a spiral column 36 fixedly connected to the upper end surface of the intermediate plate 35 .

[0035] The connecting column 8 is threadedly connected to the outer wall of the spiral column 36 through a cavity with a lower opening provided therein, wherein the thread size is set to enable the connecting column 8 and the spiral column 36 to be self-locking.

[0036] Working or installation process: When in use, the main unit 1 and the floor brush unit 2 are used for vacuuming. When the height of the floor brush unit 2 relative to the roller 5 needs to be adjusted, By turning the knob 7, the connecting post 8 is driven to rotate, so that the adjusting rod 9 switches positions in the grooves 11 of different depths. Since the auxiliary support member 6 abuts against the ground or carpet, the thrust is reversed, so that the connecting post 8 drives the housing 4 to move upward together, so that the housing 4 rotates relative to the roller 5, thereby adjusting the height of the housing 4. Alternatively, by rotating the knob 7, the connecting column 8 is driven to rotate, and then, through the threaded connection with the spiral column 36, the connecting column 8 drives the housing 4 to move upward together, so that the housing 4 rotates relative to the roller 5, thereby adjusting the height of the housing 4. The self-locking nature of the thread can achieve fixation after different height adjustments, and the thread can achieve infinite height adjustment. The height of the housing 4 can be adjusted according to the height of carpets of different heights, making it easier for the vacuum cleaner and the roller 5 to work on the carpet, thereby reducing physical effort, improving work efficiency, and improving the cleanliness of the carpet.
