Abstract: The present disclosure discloses an atomizer for an electronic cigarette, and a cartridge and an electronic cigarette having the same. The atomizer includes: a housing, an E-liquid storage chamber, an aerosol passage and an atomizing chamber are arranged in the housing; and at least one gas inlet and an inspiratory mouth are arranged on the housing; and a dimension of the housing in a thickness direction is D, a dimension of the housing in a length direction is L, and a dimension of the housing in a width direction is W, D, L and W meet: L>W?D, 5?L/D?9, and 2?W/D?5; and an atomizing core fixing member arranged in the housing and provided with an atomizing core communicating with the E-liquid storage chamber and the atomizing chamber, at least one atomization guide channel is defined between the atomizing core fixing member and an inner wall of the housing.

Abstract: A vaporization core component for electronic cigarettes, a cartridge for electronic cigarettes, and an electronic cigarette. The vaporization core component for electronic cigarettes includes a liquid guide body and a heating element. The liquid guide body has a first end surface and a second end surface. At least a part of the first end surface is a liquid absorption region. At least a part of the second end surface is a vaporization region. The heating element is arranged in the vaporization region of the second end surface. In the vaporization core component, a position of the liquid absorption region is opposite to a position of the vaporization region, and an area of the liquid absorption region is smaller than an area of the vaporization region. The heating element is arranged in the vaporization region of the second end surface.

Abstract: An electronic-cigarette vaporization component includes a housing, a vaporization core fixing device, and a vaporization core component. The housing has a liquid storage cavity, an outlet channel, and a vaporization cavity in communication with the outlet channel. An air inlet in communication with the vaporization cavity and an air outlet in communication with the outlet channel are provided on the housing. The vaporization core fixing device is arranged in the housing and formed with a mounting groove and a communication channel. The vaporization cavity has a first end in communication and a second end in communication with one end of the outlet channel distant from the air outlet. At least a portion of the communication channel is arranged obliquely with respect to the outlet channel. The vaporization core component is mounted in the mounting groove and in communication with the liquid storage cavity and the vaporization cavity respectively.
