[0002] Vacuum cleaners are primarily used for vacuuming and are cleaning devices, mainly used indoors or in cars. However, when cleaning pets, cleaning brushes are generally used and do not have a vacuuming function. Patent No. 2019224835379 discloses a pet brush and a pet vacuum cleaner that includes the brush, combining a vacuum cleaner and a cleaning brush to achieve the effect of cleaning and vacuuming simultaneously, greatly improving the cleaning effect. However, the bristle length of this vacuum cleaner is fixed, and the bristle length cannot be adjusted for pets of different lengths. Therefore, when cleaning pets with different fur lengths, it is necessary to change the brush head. To address this shortcoming, this invention proposes an improvement. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, the present invention provides a multi-functional vacuum cleaner with a cleaning brush, which can clean pet hair during vacuuming. The length of the brush bristles in the vacuum cleaner can be adjusted according to the pet's hair length. The overall structure is simple and more convenient to use.

[0004] The technical solution adopted in this invention is: a multi-functional vacuum cleaner with a cleaning brush, including a vacuum cleaner body, a suction port on the vacuum cleaner body, a cleaning brush detachably provided at the suction port, the cleaning brush being able to rotate infinitely along the suction port, the cleaning brush having bristles, and an adjustment mechanism for adjusting the bristle length inside the cleaning brush.

[0005] By adopting the above technical solution, a cleaning brush is provided on the suction port, so the pet can be cleaned while vacuuming. Since the cleaning brush can rotate infinitely along the suction port, it can be pushed and rotated while vacuuming. Due to the setting of the adjustment mechanism, it can adapt to pets with different hair lengths, making it more convenient to use.

[0006] The present invention is further configured such that: the adjustment mechanism includes a rotating cylinder; the cleaning brush includes a sleeve connected to the suction port; a cover is provided on the other end of the sleeve facing the suction port; a bristle plate is fitted on the outer surface of the sleeve; bristles are provided on the bristle plate; the rotating cylinder is fitted on the outer surface of the bristle plate; the rotating cylinder is provided with bristle holes for the bristles to extend to the outer surface of the rotating cylinder; and a rotating cover is provided on the outer edge of the cover to drive the bristle plate to rotate.

[0007] Using the above technical solution, during adjustment, the rotating cover is rotated, which drives the brush plate to rotate. During the transfer process, the bristles move within the brush holes of the rotating cylinder, thereby adjusting the bristle length. The adjustment is simple and convenient.

[0008] The invention is further configured such that: the brush plates are multiple, each brush plate has an arc-shaped cross-section, and the multiple brush plates form a cylinder; a limiting member is provided between the rotating cover and the brush plates to prevent the bristles from falling out of the brush holes. The limiting member includes a limiting sliding groove on the rotating cover corresponding to the number of brush plates, and a sliding post on the brush plate is provided within the limiting sliding groove.

[0034] like Figures 1-11 As shown, the technical solution adopted in this invention is: a multi-functional vacuum cleaner with a cleaning brush, comprising a vacuum cleaner body 1, a suction port 11 on the vacuum cleaner body 1, and a detachable cleaning brush 2 at the suction port 11. The cleaning brush 2 can rotate infinitely along the suction port 11, and the cleaning brush 2 has bristles 21. An adjustment mechanism 3 for adjusting the length of the bristles 21 is provided inside the cleaning brush 2. In the above solution, because the cleaning brush 2 is provided on the suction port 11, pets can be cleaned simultaneously with vacuuming. Since the cleaning brush can rotate infinitely along the suction port, it can be pushed and rotated during vacuuming. Furthermore, due to the adjustment mechanism 3, it can adapt to pets with different hair lengths, making it more convenient to use.

[0035] The adjustment mechanism 3 includes a rotating cylinder 31, and the cleaning brush 2 includes a sleeve 22 connected to the suction port 11. A cover 23 is provided on the other end of the sleeve 22 facing the suction port 11. A bristle plate 24 is fitted onto the outer surface of the sleeve 22, and bristles 21 are disposed on the bristle plate 24. The rotating cylinder 31 is fitted onto the outer surface of the bristle plate 24, and the rotating cylinder 31 has bristle holes 32 for the bristles 21 to extend to the outer surface of the rotating cylinder 31. A rotating cover 33 is provided on the outer edge of the cover 23 to drive the bristle plate 24 to rotate. In the above scheme, during adjustment, the rotating cover 33 is rotated, driving the bristle plate 24 to rotate. During the transfer process, the bristles 21 move within the bristle holes 32 of the rotating cylinder 31, realizing the adjustment of bristle length. The adjustment is simple and convenient.

[0036] The brush plates 24 are multiple, each with an arc-shaped cross-section, forming a cylinder. A limiting member 4 is provided between the rotating cover 33 and the brush plates 24 to prevent the bristles 21 from falling out of the brush holes 32. The limiting member 4 includes a limiting sliding groove 41 on the rotating cover 33 corresponding to the number of brush plates 24, and a sliding post 42 on the brush plate 24 placed within the limiting sliding groove 41. In the above scheme, the limiting member 4 is the limiting sliding groove 41. During rotation, the sliding post 42 can only slide within the limiting sliding groove 41, thus preventing excessive rotation that could cause the bristles 21 to leave the brush holes 32.

[0037] The limiting sliding groove 41 is an arc-shaped groove, with one end connected to the inner wall of the rotating cover 33 and the other end extending towards the inner side of the rotating cover 33, causing the limiting sliding groove 41 to form an inclined surface. In the above scheme, the limiting sliding groove 41 forms an inclined surface, which facilitates the adjustment of the bristle length.

[0038] The vacuum cleaner 1 has a cavity 12 at one end of the suction port 11, with the suction port 11 located inside the cavity 12. A bottom cover 5, adapted to the cavity 12, is provided on the end of the sleeve 22 facing the suction port 11. The bottom cover 5 is fixed to the sleeve 22 by screws 100, thus connecting the bottom cover 5. A flange 51 is provided on the bottom cover 5. A rotating groove 52, adapted to the flange 51 and capable of rotating along the flange 51, is provided on one end of the rotating cylinder 31. The other end is fitted onto the rotating cover 33. In this design, the rotating groove 52 of the rotating cylinder 31 fits onto the flange 51. During vacuuming, the rotating cylinder 31 can be rolled while vacuuming, allowing for pushing and rotating vacuuming. The brush bristles 21 can not only be used as a pet cleaning brush but also for cleaning clothes, sheets, etc., providing multiple functions and greater convenience during vacuuming.

[0039] The rotating cylinder 31 has a limiting step 6 on its inner wall facing the bottom cover 5, corresponding to the brush plate 24. The limiting step 6 has a limiting step groove 61. The bottom of the brush plate 24 has a limiting platform 62 that is placed within the limiting step groove 61 and can rotate along it. The outer surface of the limiting platform 62 is arc-shaped. In this design, the limiting platform 62 and the limiting step 6 limit the brush plate 24, preventing it from falling off. Because the brush plate 24 needs to rotate, the outer surface of the limiting platform 62 is arc-shaped, allowing it to move within the limiting step groove 61.

[0040] The brush plate 24 is provided with a plurality of dust suction holes 7, and the rotating cylinder 31 is provided with an external dust suction hole 71 that communicates with the dust suction holes 7. In the above scheme, the dust suction holes 7 are connected to the external dust suction hole 71 and to the suction port 11, which facilitates dust suction while brushing.

[0041] The outer surface of the suction port 11 is provided with a suction port limiting groove 8, and the top of the suction port limiting groove 8 is provided with a suction port opening 81. The inner surface of the sleeve 22 is provided with a limiting block 82 that matches the suction port limiting groove 8. The sleeve 22 is provided with a fixing member 9 for fixing the cleaning brush 2. In the above scheme, when installing the cleaning brush 2, the limiting block 82 is aligned with the suction port opening 81 and inserted into the suction port limiting groove 8 to realize the installation of the cleaning brush 2. The fixing member 9 fixes the cleaning brush 2.

[0042] The fixing component 9 includes a fixing block 91. A mounting seat 92 is provided on one side of the sleeve 22. A cavity 93 is provided inside the mounting seat 92. A cover opening 94 communicating with the cavity 93 is provided on the cover body 23. A cavity opening 95 communicating with the sleeve 22 is provided at the bottom of the mounting seat 92. The fixing block 91 is inserted into the cavity 93 through the cover opening 94. A limiting post 96 is provided at the corresponding position of the fixing block 91 and the cavity opening 95. At least one limiting hole 97 adapted to the limiting post 93 is provided on the other end of the suction port 11 with the suction port limiting groove. A spring 98 is provided on the inner wall of the fixing block 91 and the cavity 93. In the above scheme, when the sleeve 22 is fitted onto the suction port 11, the limiting post 93 on the fixing block 91 inserted into the cavity 93 will be inserted into the limiting hole 97 to achieve overall fixation of the cleaning brush and prevent the cleaning brush from falling off. The fixing block 91 has connecting ears 99 on both sides, and the connecting ears 99 have insert posts 90. The cavity 93 has insertion holes 10 on both sides that are adapted to the insert posts 90. When the fixing block 91 is placed in the cavity 93, the insert posts 90 are inserted into the insertion holes 10 to fix the fixing block 91. The end face of the insert post 90 facing the insertion hole 10 is inclined, which makes it easy for the insert post 91 to be inserted into the insertion hole 10 or to slide out of the insertion hole 10. The spring 98 is set to further fix the fixing block 91 in the cavity 93 to prevent the fixing block 91 from falling off. The end of the fixing block 91 facing the opening of the cavity 93 has a handle groove 20, which facilitates the installation and removal of the fixing block 91.

[0043] In this invention, the adjustment mechanism rotates the rotating cover, which in turn rotates the brush plate. During the transfer process, the bristles move within the brush holes of the rotating cylinder, thereby adjusting the length of the bristles. Of course, in addition to this rotation method, the bristles can also be adjusted by pressing.

[0044] The brush bristles in this invention can be plastic or silicone. Silicone bristles have a certain degree of elasticity, so this vacuum cleaner can be used to clean pets, as well as to clean bed sheets, clothes and other fabrics.

[0045] Please note to all technical personnel: Although the present invention has been described according to the specific embodiments above, the inventive concept of the present invention is not limited to this invention. Any modifications that utilize the inventive concept will be included within the scope of protection of this patent.
