For example, "connect" may refer to fixed connection, detachable connection or integrated connection; or, direct connection, indirect connection through an intermediate medium, or internal connection or interaction of two elements. When one element is referred to as being "over" or "under" the other element, it may be "directly" or "indirectly" located on the other element, or one or more intermediate elements may exist between these two elements. Terms such as "first", "second" and "third" in the specification are merely for the purpose of conveniently describing the technical solution of the invention, and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features referred to. So, when one feature is defined by the terms such as "first", "second" and "third", it may explicitly or implicitly indicate the inclusion of one or more said features. Those ordinarily skilled in the art can understand the specific meanings of these terms in the invention as the case may be.

- The atomizing core according to Claim 3, characterized in that in the air flow chamber (17), the heating part (21) are disposed on the base (11), and the liquid inlet part (14) is disposed on an outer side of the base (11).
- The atomizing core according to Claim 4, characterized in that the air inlet part (14) is a liquid inlet recess formed in the outer side of the base (11).
- The atomizing core according to Claim 3, characterized in that in the air flow chamber (17), the heating part (21) are disposed on the air guide part (12).
- The atomizing core according to Claim 6, characterized in that the liquid inlet part (14) is a liquid inlet recess formed in an outer side of the air guide part (12).
- The atomizing core according to Claim 3, characterized in that the air inlet (15) is formed in a joint of the base (11) and the air guide part (12).
- The atomizing core according to Claim 3, characterized in that the other end of the first part (111) and the other end of the second part (112) define the air outlet (16) therebetween.
- The atomizing core according to Claim 3, characterized in that the air inlet (15) is disposed at a lower side of the liquid transfer unit (1), and the liquid transfer unit (1) comprises a support part (13) which is connected to the base (11) and/or the air guide part (12), protrudes downwards and is used for elevating the air inlet (15).
