Referring toFIG.1toFIG.18, a cartridge of the present disclosure includes a cartridge tube10provided with a flue13and an e-liquid storage cavity12, a closure body installed in the cartridge tube10and closing the e-liquid storage cavity12, an atomizing core30installed in the closure body, a base50fixed to the cartridge tube10, and a suction nozzle20installed to a top end of the cartridge tube10.

Particularly referring toFIG.12toFIG.18, the cartridge tube10includes a tube body11, an e-liquid storage cavity12disposed in the tube body11, a flue13disposed in the tube body11and running through in a vertical direction, a mating portion15disposed at the top of the tube body11, and a first snapping portion14disposed at two sides of the bottom of the tube body11. The flue13includes a flue tube131extending from the top of the tube body11into the e-liquid storage cavity12, a smoke hole133formed in the middle of the flue tube131, and an insertion portion132formed at the bottom of the flue tube131. An outer diameter of the insertion portion132is smaller than an outer diameter of the flue tube131. Two sides of the mating portion15are provided with positioning pillars151, and an e-liquid suction cavity152disposed at a top position of the flue13. The smoke hole133at the top of the flue13is of a trumpet-shaped structure. Preferably, the flue13is disposed in the middle of the e-liquid storage cavity12. In specific implementation, the flue13may also be disposed at one side or two sides of the e-liquid storage cavity12.

Particularly referring toFIG.14toFIG.16, the suction nozzle20includes a top portion21, an insertion portion22extending downward from the top portion21, and a suction hole23running through the top portion21and the insertion portion22and communicating with the smoke hole133. Two sides of the insertion portion22are provided with positioning holes25at positions corresponding to the positioning pillars151, and an adsorption space24is provided at an outer periphery of the suction hole23. The adsorption space24is provided therein with an adsorption member26, which is disposed around the outer periphery of the suction hole23and communicates with the smoke hole133.

The adsorption member26is made of a polymer fiber material and has strong water vapor adsorption capability. During assembly, the insertion portion22of the adsorption member26is inserted into the e-liquid suction cavity152of the mating portion15at the top end of the tube body11, and the positioning pillars151are inserted into the positioning holes25of the adsorption member26. When a user sucks from the suction nozzle2, smoke moves upward from the flue13, and most water vapor in the smoke is adsorbed on the adsorption member26.

In specific implementation, the adsorption member26may completely cover an upper part of the smoke hole133, so that the smoke can be sucked by the user only through the adsorption member26. In this case, the adsorption member26is required to have strong permeability, so as to avoid being blocked. The suction nozzle is made of a food-grade TPE material, or other food-grade soft rubber material.

According to the cartridge in the present disclosure, the top of the cartridge tube10is provided with a mating portion15, the mating portion15is provided with a separate suction nozzle20, the suction nozzle20is provided therein with an adsorption member26communicating with the flue13, and the adsorption member26adsorbs most water vapor in the smoke, to avoid downward seepage of water vapor into a cigarette pole caused by water vapor condensation in the flue13, thereby avoiding an influence on an electronic device of the cigarette pole.

Particularly referring toFIG.2toFIG.9andFIG.17, the closure body includes a closure member40and a sealing member60integrally formed on the closure member40. The closure member40includes a closure end41, two accommodation ends42extending downward from two transverse sides of the closure end41, an air passage45recessed downward from the middle of the closure end41, two e-liquid passages43running through two sides of the closure end41and communicating with each other at a position below the bottom of the air passage45, and a notch44provided at the accommodation end42. The notch44is open in a longitudinal direction, and a stop portion441is formed at two longitudinal sides of the top of the notch. The air passage45includes a connection air passage453running through the closure end41in a vertical direction, a longitudinal air passage451running through the closure end41in a longitudinal direction, and an outer-side air passage452extending downward along an outer wall surface of the closure end41from an outer edge of the longitudinal air passage451. A groove421is formed at the outer periphery of the bottom of the accommodation end42.

The sealing member60is integrally formed on the closure member40. The sealing member60includes a first sealing portion61formed at the outer periphery of the accommodation end42, a second sealing portion62extending from the first sealing portion61to the closure end41, and a third sealing portion63formed at an outer periphery of the top of the closure end41and integrally connected to the second sealing portion62. The first sealing portion61includes a first sealing ring612integrally formed around outer peripheries of the accommodation end42and the notch44and an atomizing core installation cavity611formed at a bottom surface of the stop portion441of the notch44and at an inner side surface of the accommodation end42. The atomizing core installation cavity611is recessed inward, corresponding to an outer surface of a sidewall where the outer-side air passage452is disposed, to form a recessed channel614communicating with the outer-side air passage452. A lower end portion of the recessed channel614runs through a sidewall of the atomizing core installation cavity611to form a perforation613. The perforation613, the recessed channel614, the outer-side air passage452, the longitudinal air passage451, and the connection air passage453jointly form the air passage45.

Two sides of each of the outer-side air passage452, the recessed channel614, and the perforation613are provided with second sealing portions62, that is, the outer-side air passage452, the recessed channel614, and the perforation613are disposed between two second sealing portions62.

The third sealing portion63includes a second sealing ring631integrally formed around the outer periphery of the closure end41, a third sealing ring633integrally formed at an inner wall surface of the connection air passage453, and an e-liquid inlet hole632disposed corresponding to the e-liquid passage43.

The atomizing core30is assembled to an upper end of the atomizing core installation cavity611of the sealing member60. The periphery of the atomizing core30is surrounded by the sidewall of the atomizing core installation cavity611. The atomizing core30is disposed above the perforation613, an atomizing cavity80is formed below the atomizing core30, and the perforation613communicates with the atomizing cavity80. Upper edges of two longitudinal sides of the atomizing core30are abutted by the stop portion441to prevent the atomizing core30from moving upward. Two transverse sides of the atomizing core30abut against an inner wall surface of the accommodation end42.

Particularly referring toFIG.2andFIG.10, the atomizing core30includes a seepage surface31exposed to the e-liquid passage43and in contact with e-liquid in the e-liquid passage43and an atomizing surface32disposed above the atomizing cavity80. The atomizing surface32is provided with a heating wire33for heating the atomizing core30. The atomizing core30is made of a porous ceramic material.

The closure body is inserted from the bottom of the cartridge tube10. After insertion, the insertion portion133at a free end of the flue13is inserted into the connection air passage453of the closure member40and clamps, with the inner wall surface of the connection air passage453, the third sealing ring633of the sealing member60to achieve sealing. The first and second sealing rings612and631respectively compress an inner wall surface of the tube body11of the cartridge tube10to achieve a double-sealing structure. The second sealing portion62compresses the inner wall surface of the tube body11so that the air passage45is sealed independently.

The e-liquid stored in the e-liquid storage cavity12enters the e-liquid passage43of the closure member40through the e-liquid inlet hole632of the sealing member60, so that the e-liquid is fully in contact with the seepage surface31of the atomizing core30disposed below the e-liquid passage43. When the air passage45inhales in the flue13, smoke atomized by the atomizing cavity80successively passes through the perforation613, the recessed channel614, the outer-side air passage452, and the longitudinal air passage451, then finally enters the flue13through the connection air passage453and is sucked out.

When the sealing member60is injection-molded, the first and third sealing portions61and63are integrally connected through the second sealing portion62.

According to the closure body of the present disclosure, the sealing member60is integrally formed on the closure member40, and there is no need to assemble the sealing ring separately, which can easily achieve automatic assembly. In the sealing member60, first and second sealing rings612and631are formed respectively at the closure end41and the accommodation end42of the closure member40. The second sealing ring631, as the first sealing means, is in direct contact with the e-liquid storage cavity12, and the air passage45disposed between the first and second sealing rings612and631is independently sealed by the second sealing portion62, so the air passage45may not be polluted even if there is e-liquid seeping out of the second sealing ring631.

Still referring toFIG.2,FIG.11, andFIG.17, the base50includes a base body51and an extension portion52extending upward from the base body51and inserted into the cartridge tube10. Two transverse ends of the extension portion52are provided with second snapping portions53snapped with first snapping portions14at two transverse sides of the tube body11of the cartridge tube10. The first and second snapping portions14and53are respectively in the structure of clamping holes and clamping blocks. The base50is integrally formed with at least one pair of conductive pillars55and an air inlet hole54running through the base50and communicating with the atomizing cavity80. One pair of conductive pillars55respectively electrically press two ends of the heating wire33to transmit electric energy to heat the heating wire. The conductive pillars55may be elastic contact members, which abut against the heating wire33with elastic force and provide a certain support for the atomizing core30to prevent the atomizing core30from moving down and falling off under a strong external force.

Still referring toFIG.1toFIG.18, an automatic assembly method for the cartridge in the present disclosure is as follows:

In S01, a cartridge tube10is provided, and the cartridge tube10undergoes an automatic process line, in which the cartridge tube10is in an inverted state.

In S02, e-liquid is injected into an e-liquid storage cavity12of the cartridge tube10. At this time, the injected e-liquid cannot exceed an insertion portion133of a flue13.

In S03, a closure body is provided, and the closure body is automatically pressed into the cartridge tube10to close an outer periphery of the e-liquid storage cavity12and close communication between the e-liquid storage cavity12and the flue13; an atomizing core611is formed at one end of the closure body away from the e-liquid storage cavity12; and the closure body is provided therein with an e-liquid passage43and a flue45independent from each other.

In this step, the closure body includes a closure member40and a sealing member60integrally formed on the closure member40. The structures of the closure member40and the sealing member60have been described in detail previously, and are not described in details herein.

In S04, an atomizing core30is provided, the atomizing core30is automatically pressed into the atomizing core installation cavity611, to finally close the e-liquid passage43in the closure body by the atomizing core30.

In S05, a base50on which conductive pillars55are formed is provided, the base50is automatically pressed into the bottom of the cartridge tube10to hold the base50on the cartridge tube10for fixation, a top end of the base50abuts against the bottom of the closure body, and the conductive pillars55are electrically in upward contact with the atomizing core30.

According to the closure body of the cartridge of the present disclosure, the closure member40and the sealing member are integrally formed, to avoid the defect that separated sealing rings need to be manually assembled and cannot be automatically assembled. Meanwhile, for the cartridge of the present disclosure, the atomizing core30is directly fixed into the atomizing core installation cavity611of the closure body, there is no need that the base50and the closure body clamp the atomizing core30, the bottom of the atomizing core30is supported only by the conductive pillars55, while a clamping force regarding the atomizing core30is from an elastic cavity wall of the atomizing core installation cavity611. In this way, it only needs to directly automatically press the closure body, the atomizing core30, and the base50successively into the cartridge tube10, which simplifies the flow of automatic assembly. At the same time, according to the present disclosure, minimum number of parts are needed, which makes assembly thereof easier.

The above descriptions are merely embodiments of the present disclosure, and are not intended to limit the present disclosure. For those skilled in the art, the present disclosure may have various alterations and changes. Any modification, equivalent replacement, improvement, and the like made within the principle of the present disclosure shall fall within a scope claimed by claims of the present disclosure.
