Description

Technical Field

[0001] The invention relates to an electronic smoking device, in particular to an electronic cigarette atomization core and an assembly method thereof, and an atomizer. Background Art

[0002] In existing ultrasonic atomizers, the contact position between the oil-conducting cotton and the spring is prone to be skewed during assembly, causing the spring to directly contact the surface of the ultrasonic atomizer. During the operation of the ultrasonic atomizer, the ultrasonic atomizer has friction with the oil-conducting cotton due to the high-frequency oscillation of the ultrasonic atomizer. When the contact position between the oil-conducting cotton and the spring is skewed, the part of the oil-conducting cotton that is pressed by the skew is more likely to be worn, and the ultrasonic atomizer's protective layer is worn due to direct contact with the spring, thereby affecting the ultrasonic atomizer's atomization effect on the smoke oil, and affecting the life of the oil-conducting cotton and the ultrasonic atomizer. Summary of the invention

[0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide an electronic cigarette atomization core and an assembly method thereof, and an atomizer which can increase the service life of oil-conducting cotton and an ultrasonic atomization sheet.

[0004] In order to solve the above technical problems, the present invention provides an electronic cigarette atomization core, including oil-conducting cotton, wherein the oil-conducting cotton at least includes guiding parts located at both ends and an abutting part located in the middle, and the abutting part of the oil-conducting cotton abuts against the upper surface of the ultrasonic atomization sheet through the end of the spring, and the width of the abutting part is greater than the width of the guiding part, and the abutting part covers the end of the spring so that the end of the spring is completely located in the abutting part.

[0005] The abutment portion of the oil-conducting cotton of the present invention is used for abutting contact with the ultrasonic atomizing sheet, and the guiding portion is used for connecting with the oil outlet of the outer sleeve so that the smoke oil reaches the ultrasonic atomizing sheet through the oil-conducting cotton. The width of the abutment portion is set to be larger than the width of the guiding portion, so as to facilitate the user in assembling. The contact end of the spring and the ultrasonic atomizing sheet can be wrapped by the abutment portion of the oil-conducting cotton, thereby avoiding that a part of the contact end of the spring and the ultrasonic atomizing sheet abuts against the abutment portion of the oil-conducting cotton and the other part directly presses on the protective layer of the ultrasonic atomizing sheet, that is, avoiding that the heat released during the working process of the ultrasonic atomizing sheet is directly absorbed by the spring, resulting in the burning or carbonization and blackening of the guiding portion of the oil-conducting cotton in contact with the abutment portion when the spring is at high temperature, and the protective layer in contact with the ultrasonic atomizing sheet is also worn out.

[0006] Furthermore, the electronic cigarette atomization core also includes an outer sleeve and an inner sleeve which are sleeved with each other, the outer sleeve is provided with an oil passage port, the outer periphery of the inner sleeve is provided with a guide groove corresponding to the oil passage port, and the guide portion is arranged in the guide groove to prevent the guide portion of the oil guide cotton from wrinkling and affecting the guide effect of the smoke oil.

[0007] Furthermore, a first guide surface is arranged on the outer periphery of the inner sleeve, a second guide surface is arranged in the inner cavity of the outer sleeve, and the first guide surface of the inner sleeve is arranged corresponding to the second guide surface of the outer sleeve. In this way, through the cooperation of the first and second guide surfaces, the oil-guiding cotton and the oil port of the outer sleeve can be quickly aligned.

[0008] Furthermore, a second fixing hole is provided in the upper part of the inner cavity of the inner sleeve, a fixing ring is installed in the upper part of the inner cavity of the outer sleeve, and the lower end of the fixing ring is placed in the second fixing hole, so that a cotton-clamping gap is formed between the fixing ring and the inner sleeve, and the end of the guide part extends along the guide groove into the cotton-clamping gap and is squeezed and fixed by the fixing ring.

[0009] Furthermore, a first fixing hole for installing the spring is provided at the lower portion of the inner cavity of the inner sleeve, so that the spring can be stably installed between the inner sleeve and the ultrasonic atomization sheet.

[0010] Based on the same inventive concept, the present invention provides an assembly method of the electronic cigarette atomizer core, which comprises:

[0011] 1) Install the ultrasonic atomizer and electrode assembly in the outer sleeve;

[0012] 2) One end of the spring is held against the first fixing hole of the inner sleeve, and the other end of the spring is pressed against the abutment portion of the oil-conducting cotton, and the end of the spring is completely covered by the abutment portion of the oil-conducting cotton to prevent the spring from being exposed from the abutment portion and directly contacting the surface of the ultrasonic atomizer;

[0013] 3) The guide portion of the oil-conducting cotton extends along the guide groove of the inner sleeve, and the end of the guide portion is bent toward the second fixing hole of the inner sleeve; the yield rate can be further improved by manual screening and inspection;

[0014] 4) Insert the lower end of the fixing ring into the second fixing hole so that the end of the guide portion is squeezed and fixed to the inner wall of the inner sleeve by the fixing ring, thereby determining the abutting position between the spring and the abutting portion;

[0015] 5) The fixing ring fixes the oil-conducting cotton to the inner sleeve to form a whole, which is inserted into the outer sleeve with the help of the cooperation between the first guide surface of the inner sleeve and the second guide surface of the outer sleeve, so that the oil port of the outer sleeve is connected with the guide part of the oil-conducting cotton.

[0016] Based on the same inventive concept, the present invention also provides an electronic cigarette atomizer, which includes an oil bin device and the electronic cigarette atomizer core, wherein an oil bin is arranged in the oil bin device, an oil outlet is arranged on the oil bin, and the oil outlet is connected to the guide portion of the oil guide cotton.
