[0068] It should also be further noted that the liquid contained in the atomizing body 61 of the atomizing unit 60 can be water, moisturizing liquid, cleaning liquid, hair repair liquid, etc.; and the atomizing body 61 is used to atomize the above-mentioned liquid.

[0069] Unlike existing technologies, the above technical solution, through the arrangement of the first suction port 12 and the brush head unit 30, allows the first suction port 12 to quickly remove the hair scraped by the brush head unit 30. Simultaneously, through the arrangement of the spray unit 60, the pet brush can promptly spray mist after scraping hair to repair and / or nourish the pet's fur.

[0070] Please see Figure 2 In this embodiment, the brush head unit 30 is placed between the first suction port 12 and the spray port 64.

[0071] In this embodiment, along the combing direction (the direction in which the brush moves), the spray nozzle 64 is positioned on the side of the brush head unit 30 away from the direction of brush movement; that is, after the brush head unit 30 has cleaned the hair, further cleaning and / or maintenance of the hair can be achieved through the spray nozzle 64.

[0072] Furthermore, when the brush head unit 30 removes hair, the first suction port 12 located on the side of the brush head unit 30 near the direction of brush movement can promptly suck up the removed hair.
