1. A capillary liquid conducting and atomizing unit, comprising a housing (10) and an atomization assembly (20) arranged in the housing (10); wherein at least one liquid inlet (200) is provided in a side of the atomization assembly (20), and a capillary liquid absorbing channel (100) communicating with the liquid inlet (200) is provided between an inner side of the housing (10) and a side of the atomization assembly (20) where the liquid inlet (200) is located; and a length direction of the capillary liquid absorbing channel (100) extends along a height direction of the side where the liquid inlet (200) is located, and two opposite ends of the capillary liquid absorbing channel (100) respectively extend towards an upper side and a lower side of the liquid inlet (200), to absorb liquid into the liquid inlet (200) by capillary action; one end of the housing (10) is enclosed to form an enclosed end (110), and the atomization assembly (20) is located on an inner end surface of the enclosed end (110); an inner wall surface of the housing (10) comprises a first wall surface (101) corresponding to the side of the atomization assembly (20) where the liquid inlet (200) is located, and a gap is formed between the side of the atomization assembly (20) and the first wall surface (101) to form the capillary liquid absorbing channel (100); other inner wall surfaces of the housing (10) form a second wall surface (102) that is spaced apart from and corresponding to other sides of the atomization assembly (20); and a first space between the other sides of the atomization assembly (20) and the second wall surface (102) forms a liquid storage cavity (103) communicating with the capillary liquid absorbing channel (100); a support base (120) is provided on the inner end surface of the enclosed end (110) of the housing (10), and the atomization assembly (20) is arranged on the support base (120); a second space (104) communicating with the liquid storage cavity (103) is defined between an outer periphery of the support base (120) and an inner wall surface of the housing (10).
