Description

Electronic cigarette core, assembling method and atomizer

Technical field

The invention relates to an electronic cigarette, in particular to an electronic cigarette core and its assembly method and an atomizer.

Background technique

In the existing ultrasonic atomizer, the contact position of the oil guide cotton and the spring is likely to be skewed during assembly, causing the spring to directly contact the surface of the ultrasonic atomizer. During the working process of the ultrasonic atomizing film, due to the high frequency oscillation of the ultrasonic atomizing film, the ultrasonic atomizing film and the oil guiding cotton friction phenomenon. When the contact position of the oil guiding cotton and the spring is skewed, the part of the oil guiding cotton pressed by the skewed It is easier to be worn, and the protective layer of the ultrasonic atomizer is worn out by the direct contact of the spring, which affects the atomization effect of the ultrasonic atomizer on the smoke oil, and affects the life of the oil guide cotton and the ultrasonic atomizer.

Summary of the invention

The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an electronic cigarette wick, an assembly method and an atomizer that can increase the life of the oil-conducting cotton and the ultrasonic atomizer.

The oil-conducting cotton at least includes a guide part at both ends and a contact part in the middle. The end of the spring abuts against the upper surface of the ultrasonic atomization sheet, the width of the abutment is greater than the width of the guide, and the abutment wraps the end of the spring so that the The end of the spring is completely located in the abutting portion.

The abutting part of the oil-conducting cotton of the present invention is used for abutting contact with the ultrasonic atomizing sheet, and the guiding part is used to connect with the oil outlet of the outer tube so that the smoke oil reaches the ultrasonic atomizing sheet through the oil-conducting cotton, and the abutting part The width of is set to be larger than the width of the guide part, so that when assembling the atomizer core, the contact end of the spring and the ultrasonic atomizer can be wrapped by the abutment part of the oil guide cotton to avoid the spring and the ultrasonic atomizer. A part of the contact end is in contact with the abutting part of the oil-conducting cotton, and the other part is directly pressed against the protective layer of the atomization area of the ultrasonic atomization sheet, which is to prevent the heat released during the operation of the ultrasonic atomization sheet from being directly absorbed by the spring. As a result, when the spring is at a high temperature, the oil-conducting cotton in contact with the spring will burn through or be carbonized and blackened, and prevent the protective layer of the ultrasonic atomization sheet from being worn out, thereby improving the efficiency of the oil-conducting cotton and the ultrasonic atomization sheet. life.
