Technical Field

The invention particularly relates to an electronic cigarette atomizing core and an atomizer.

Background

Be equipped with rotatory oiling structure among current electron smog spinning disk atomiser, it has following shortcoming: when sealed intercommunication oil sump and the cotton inlet port of atomizing, generally rely on the relative rotation of adapter sleeve and outer tube, because adapter sleeve and outer tube are the metalwork, when two metalwork cooperations of needs rotate, to the cooperation size required precision of two metalworks very high, the equipment is also very troublesome simultaneously, so the production worker is long and manufacturing cost is high, and sealed effect is not good, has the oil leak and inhales the risk of oil.

Disclosure of Invention

In the present electron smog spinning disk atomiser, rely on two metalworks to rotate relatively and seal the inlet port, so the production engineering is long and manufacturing cost is high, and sealed effect is not good, has the risk of oil leak and oil absorption. The invention aims to provide an electronic cigarette atomizing core and an atomizer aiming at the defects of the prior art, and the electronic cigarette atomizing core and the atomizer are short in production time, low in production cost and good in sealing effect.

In order to solve the technical problems, the technical scheme adopted by the invention is as follows:

an electronic cigarette atomizing core comprises an atomizing part, an outer sleeve, a connecting sleeve and atomizing cotton, wherein the lower section of the connecting sleeve is sleeved outside the upper section of the outer sleeve, the outer sleeve is sleeved outside the atomizing cotton, and a first oil passing hole which can communicate an inner cavity of an electronic cigarette oil bin with the atomizing cotton is formed in the outer sleeve; the connecting sleeve can axially move or circumferentially rotate relative to the outer sleeve to close or open the first oil passing hole, and a buffer sealing structure used for sealing the first oil passing hole when the first oil passing hole is closed is arranged between the connecting sleeve and the outer sleeve.

By means of the structure, when the oil way needs to be cut off (such as oil injection and long-term standing of the electronic cigarette), the driving connecting sleeve can axially move or circumferentially rotate relative to the outer sleeve to close or open the first oil passing hole. Because the buffer sealing structure is arranged between the connecting sleeve and the outer sleeve, the requirement on the precision of the matching size of the connecting sleeve and the outer sleeve is low, the assembly is convenient, the production time is short, the production cost is low, the sealing effect is good, and the risks of oil leakage and oil absorption are avoided.

As a preferable mode, the buffer sealing structure comprises a sealing gasket fixedly sleeved outside the lower section of the outer sleeve, and the top surface of the sealing gasket is positioned below the lowest point of the first oil passing hole or is tangent to the lowest point of the first oil passing hole; when the connecting sleeve moves to the bottom end of the connecting sleeve along the axial direction of the electronic cigarette and is abutted to the sealing gasket, the first oil passing hole is closed; when the connecting sleeve moves to the bottom end of the connecting sleeve along the axial direction of the electronic cigarette and is separated from the sealing gasket, the first oil passing hole is opened.

When the oil way needs to be cut off (such as during oil injection and during long-term standing of the electronic cigarette), the connecting sleeve is driven to move close to the direction of the sealing gasket along the axial direction of the electronic cigarette, and finally the connecting sleeve abuts against the sealing gasket, so that the first oil passing hole is closed, the oil way is cut off, and the oil bin inner cavity and the atomized cotton are in a cut-off state. When the oil circuit needs to be opened, the driving connecting sleeve moves away from the direction of the sealing gasket along the axial direction of the electronic cigarette, finally, the first oil passing hole is opened, the oil circuit is communicated, and the oil bin inner cavity and the atomizing cotton are in a communicated state.

Furthermore, the bottom surface of the sealing gasket is provided with a stress deformation structure.

As a preferred mode, the forced deformation structure comprises a blind hole formed in the bottom surface of the sealing gasket, and the sealing effect is better.

As another preferable mode, the connecting sleeve is provided with an oil inlet hole which can communicate the electronic cigarette oil bin with the first oil passing hole, and when the connecting sleeve rotates circumferentially relative to the outer sleeve, the oil inlet hole and the first oil passing hole are staggered or opposite to each other so as to close or open the first oil passing hole.

Furthermore, the buffering sealing structure comprises a sealing sleeve sleeved between the outer sleeve and the connecting sleeve, a second oil passing hole opposite to the first oil passing hole is formed in the sealing sleeve, and the second oil passing hole is communicated with the first oil passing hole and the atomized cotton.

Furthermore, the outer sleeve is provided with a clamping hole for preventing the sealing sleeve from axially rotating, and the sealing sleeve is provided with a boss matched with the clamping hole.

The clamping hole is matched with the boss, so that the sealing sleeve and the outer sleeve are reliably fixed, and the sealing sleeve is prevented from being driven to rotate in the rotating process of the connecting sleeve.

Furthermore, a convex ring facing the connecting sleeve is arranged on the sealing sleeve along the periphery of the second oil passing hole, and the convex ring can reliably seal the oil inlet hole.

Preferably, the atomizing member comprises an ultrasonic atomizing plate.

Based on the same inventive concept, the invention also provides an electronic cigarette atomizer which comprises the electronic cigarette atomizing core.

Compared with the prior art, the invention has the advantages of short production working hour and low production cost, and can realize the omnibearing sealing between the atomized cotton and the oil bin.
