Abstract: Disclosed is an electronic cigarette atomizer including a liquid cartridge (6) and an ultrasonic atomization piece (42) mounted vertically. The liquid cartridge (6) is located above the ultrasonic atomization piece (42), a liquid guide channel (311) communicated with the liquid cartridge (6) is disposed below the liquid cartridge (6), a liquid outlet (331) is horizontally disposed in the liquid guide channel (311), and the caliber of the liquid outlet (331) is smaller than that of the liquid guide channel (311); and liquid guide cotton (43) is horizontally mounted across the ultrasonic atomization piece (42). The liquid guide cotton (43) is in contact with or attached to an atomization surface of the ultrasonic atomization piece (42), and the liquid outlet (331) abuts against the liquid guide cotton (43). With the electronic cigarette atomizer, when smoking, e-liquid is supplied in time, and e-liquid supply and ultrasonic atomization are balanced, such that the burning phenomenon can be prevented.

Abstract: An electronic cigarette atomizing core and an atomizer are disclosed. The electronic cigarette atomizing core includes an outer sleeve and an inner sleeve, wherein the outer sleeve is provided with a liquid passing port. An atomization cavity is provided between the bottom of the inner sleeve and the ultrasonic atomization piece. A liquid guide cotton in communication with the liquid passing port is sandwiched between the outer sleeve and the inner sleeve. The inner sleeve is longitudinally provided with a main air groove and an auxiliary air groove at intervals. The cross sectional area of the auxiliary air groove is ¼ to ? the size of the cross sectional area of the main air groove. The main air groove is in communication with the atomization cavity. An auxiliary air inlet, an auxiliary air channel, the auxiliary air groove, and the atomization cavity are in communication with each other.

Abstract: An electronic cigarette atomizer and an electronic cigarette are disclosed. The electronic cigarette atomizer comprises an air inlet (1), an air inlet passage (2), an atomization cavity (3), an air outlet passage (4), an air outlet (5), and a suction nozzle (6) communicated sequentially, and further comprises an adjustment mechanism (7) for adjusting the air output of the air outlet. The adjustment mechanism (7) simultaneously adjusts the air input of the air inlet (1) and the air output of the air outlet (5). The electronic cigarette atomizer can adjust the air output of the air outlet (5) of the atomizer and can meet the needs of users with different lung capacities for different smoke concentration adjustment modes. The electronic cigarette atomizer can simultaneously adjust the air flow at the air inlet (1) and the air outlet (5) of the atomizer.

Abstract: An atomizing sheet assembly, an atomizer, and an electronic cigarette are disclosed. The atomizing sheet assembly comprises an e-liquid guide member, an atomizing sheet, and an atomizing seat. The atomizing sheet is fixed on the atomizing seat. The e-liquid guide member is in contact with an atomizing surface of the atomizing sheet. The atomizing seat is made of an elastic material. The e-liquid guide member is flaky. The atomizing seat is provided with a through hole. The flaky e-liquid guide member passes through the through hole and is in contact with the atomizing sheet. The atomizing sheet assembly can effectively adjust the e-liquid guide rate.

Abstract: Disclosed are an electronic cigarette atomization core (4) and atomizer. The electronic cigarette atomization core (4) includes an ultrasonic atomization piece (46) disposed horizontally, a liquid guide cotton (45) disposed above the ultrasonic atomization piece (46), and an electrode plate (47) placed on the liquid guide cotton (45). Each end of the electrode plate (47) is provided with a curved segment (472). The curved segment (472) includes a first contact (4721) located above a second contact (4722), wherein the first contact (4721) and the second contact (4722) are electrically connected but are distant horizontally, and the second contact (4722) abuts against an atomization surface electrode of the ultrasonic atomization piece (46) to form an electrical connection.
