The upper connector 32 and the lower connector 33 are connected by a hinge. A flexible bending tube 34 is installed inside the upper connector 32 and the lower connector 33. This flexible bending tube 34 connects the upper connector 32 and the lower connector 33, ensuring that the upper connecting tube 30 and the lower connecting tube 31 remain connected during bending. At the same time, a number of locking holes 35 are provided on the side wall of the upper connector 32. Meanwhile, the outer casing 36 covers the upper connector 32 and the lower connector 33. A locking pin 37 is provided inside the outer casing 36. When the outer casing 36 is installed, the locking pin 37 is inserted into the locking hole 35. At the same time, a cover 38 is provided at the lower end of the outer casing 36, and a protrusion 39 is provided at the upper end of the lower connector 33. The cover 38 can cover the protrusion 39 to complete the stable installation of the outer casing 36. The installation of the outer casing 36 can make the upper connecting pipe 30 and the lower connecting pipe 31 form a straight rod shape, ensuring the stability of the upper connecting pipe 30 and the lower connecting pipe 31, thereby improving the vacuum cleaner's performance.

[0051] The upper connector 32 has connecting rod grooves 320 on both sides of its sidewall. A filter connecting rod is installed inside each connecting rod groove 320. The transition connecting rod 321 has an arc-shaped structure. A button groove 322 is provided on one sidewall of the upper connector 32, and a locking groove 323 is provided on the other sidewall. Both ends of the transition connecting rod 321 are inserted into the button groove 322 and the locking groove 323, respectively. A groove for installing a press button 324 is provided in the middle sidewall of the button groove 322. A shaft for the press button 324 is provided in the middle of the press button 324. This shaft is inserted into a groove on the inner wall of the button groove 322, enabling the press button to swing. One end of the press button 324 is connected to the filter connecting rod. A locking groove 323 has a... A groove with a locking plate 325 is provided. A shaft for installing the locking plate 325 is installed in the middle of the locking plate 325. The shaft is inserted into a groove on the inner wall of the locking groove 323 to complete the swing connection of the locking plate 325. The locking plate 325 is connected to the lower end of the transition connecting rod 321. At the same time, a locking block 330 is provided on the lower connector 33. The locking plate 325 and the locking block 330 are engaged. When it is necessary to separate and bend the upper connector 32 and the lower connector 33, the pressing button 324 is pressed down, causing the pressing button 324 to swing, which pulls up the transition connecting rod 321 and drives the locking plate 325 to swing, separating it from the locking block 330. This completes the separation of the upper connector 32 and the lower connector 33, thereby enabling the connecting tube 3 to be bent, which can improve the use effect of the vacuum cleaner.

[0052] The connector tube 5 includes a connector seat 50 and an adapter 51. The connector seat 50 is connected to the vacuum brush head 4, and the adapter 51 is inserted into the lower connecting tube 31. At the same time, a connector notch 52 is provided on the side wall of the connector seat 50. The connector seat 50 and the adapter 51 are hinged together, and a connector hose 53 connects the connector seat 50 and the adapter 51. This structure allows the adapter 51 and the connector seat 50 to swing when the vacuum brush head 4 is in contact with the ground during vacuuming. The connector notch 52 allows for a larger swing angle, improving the vacuuming effect.

[0053] The top of the vacuum cleaner brush head 4 is provided with a brush head buckle 42, and the end of the adapter 51 is provided with a brush head locking block 43. The brush head locking block 43 can be engaged with the brush head buckle 42, so that the connecting tube 3 and the vacuum cleaner brush head 4 are at right angles. This makes it easier to keep the vacuum cleaner upright when it is placed, making it convenient to store and thus improving its performance.

[0054] The vacuum cleaner brush head 4 has a vacuum chamber 44 at its bottom. A bristle roller 40 is installed inside the vacuum chamber 44, and several vacuum bristles 45 are mounted on the roller 40 in a spiral arrangement. During vacuuming, the roller 40 rotates under the drive of the motor 41, agitating the dust on the floor and improving the vacuuming effect. Several vacuum grooves 46 are located on the front side of the vacuum chamber 44, further enhancing the vacuuming effect. Floor brush bristles 47 are installed on the side and tail of the vacuum chamber 44. These bristles push the dust as the brush head 4 moves, facilitating dust collection and further improving the vacuuming effect, thus enhancing the overall performance of the vacuum cleaner.

[0055] The bottom surface of the vacuum brush head 4 is provided with several rollers 48, two of which are installed on both sides of the front end face of the vacuum brush head 4, and one of which is installed at the tail end of the vacuum brush head 4. The rollers 48 can improve the movement of the vacuum brush head 4, facilitate the movement of the vacuum brush head 4 during the vacuuming process, and thus improve the use effect of the vacuum cleaner.
