In use, the e-liquid stored in the liquid storage assembly <NUM> flows into the atomizing assembly <NUM>, and the power supply device <NUM> supplies power to the atomizing assembly <NUM>, so that the e-liquid is heated by the atomizing assembly <NUM> to generate smoke, and the smoke can be inhaled by the user, wherein the connecting assembly <NUM>, the atomizing assembly <NUM> and the power supply device <NUM> jointly constitute an atomizing device (not labelled).

Please refer to <FIG>, <FIG>, and <FIG>, in this embodiment, the connecting assembly <NUM> of the atomizing device for electronic cigarettes includes a connecting sleeve <NUM> with a cavity therein and a cartridge connecting seat <NUM> connected to one end of the power supply device <NUM>. The connecting sleeve <NUM> is detachably connected to the cartridge connecting seat <NUM>, for example, by means of snapping connection or threaded connection, etc.. The upper end of the connecting sleeve <NUM> and the upper end of the cartridge connecting seat <NUM> are spaced apart along the longitudinal axis of the power supply device <NUM>. The atomizing assembly <NUM> is at least partially received in the space between the upper end of the connecting sleeve <NUM> and the upper end of the cartridge connecting seat <NUM>. The upper end, lower end, etc. mentioned herein refer to the reference direction in normal use of the electronic cigarette, for example, when the electronic cigarette is placed on the desktop or held by the user, rather than an absolute definition.

Referring to <FIG>, the liquid storage assembly <NUM> includes a liquid storage tube <NUM> and an end cover <NUM> provided at the lower end of the liquid storage tube <NUM>.

The liquid storage tube <NUM> includes an upper section and a lower section connected to the upper section. The inner diameter of the upper section is smaller than that of the lower section. The lower end surface of the liquid storage tube <NUM> is recessed upward along the axial direction of the liquid storage tube <NUM> to form an annular cavity. The annular cavity constitutes a liquid storage chamber <NUM> for storing e-liquid. The upper end of the liquid storage chamber <NUM> is closed, and the lower end of the liquid storage chamber <NUM> is an open end. The liquid storage tube <NUM> is provided with an air inlet passage <NUM> and an air outlet passage <NUM> therein, which are also provided along the axial direction of the liquid storage tube <NUM>. The air inlet passage <NUM> and the air outlet passage <NUM> are each spaced apart from the liquid storage chamber <NUM>. The side wall of the liquid storage tube <NUM> is provided with an air inlet hole <NUM> along the radial direction of the liquid storage tube <NUM>. An air outlet hole <NUM> is provided on the upper end surface of the liquid storage tube <NUM>. The air inlet hole <NUM> is in communication with the outside atmosphere and the upper end of the air inlet passage <NUM>, and the lower end of the air inlet passage <NUM> extends through the lower end surface of the liquid storage tube <NUM>. The lower end of the air outlet passage <NUM> extends through the lower end surface of the liquid storage tube <NUM>, and the upper end of the air outlet passage <NUM> is in communication with the air outlet hole <NUM>. When the user inhales, the outside air enters through the air inlet hole <NUM>, and then sequentially passes through the air inlet passage <NUM> and the air outlet passage <NUM>, and finally the generated smoke is brought into the user's mouth through the air outlet hole <NUM>.

It can be understood that, during the user's suction process, the hot airflow in the air outlet passage <NUM> can preheat the e-liquid in the liquid storage chamber <NUM>, so that the e-liquid has a relatively high temperature before it enters the atomizing assembly <NUM>, which can enhance the e-liquid atomizing efficiency and reduce energy consumption at the same time.

The end cover <NUM> has a substantially circular-shaped plate structure. The end cover <NUM> is hermetically installed at the lower open end of the liquid storage chamber <NUM>. In this embodiment, the lower end surface of the end cover <NUM> extends downward along the axial direction of the end cover <NUM> to form two oppositely arranged connecting tubes <NUM>. Each connecting tube <NUM> is opened at both ends and is in communication with the liquid storage chamber <NUM>.

The connecting assembly <NUM> includes a connecting sleeve <NUM> and a connecting member <NUM> installed in the lower end of the connecting sleeve <NUM>. The connecting sleeve <NUM> is substantially a hollow cylindrical structure with both ends being opened. The connecting sleeve <NUM> is sleeved around the lower end of the liquid storage tube <NUM>. When installing the liquid storage assembly <NUM>, only the lower end of the liquid storage tube <NUM> needs to be inserted into the connecting sleeve <NUM>. In addition, one of the inner wall of the connecting sleeve <NUM> and the outer wall of the liquid storage tube <NUM> is provided with a locking protrusion (not labelled), the other one is provided with a locking groove (not labelled) to be engaged with the locking protrusion. The engagement relationship between the locking protrusion and the locking groove can further improve the connection stability between the connecting assembly <NUM> and the liquid storage assembly <NUM>.

In addition, the liquid storage tube <NUM> is made of transparent or translucent material, so that the user can observe the residual amount of e-liquid in the liquid storage chamber <NUM> through the liquid storage tube <NUM>, and facilitate the user to replace the liquid storage tube <NUM> in time. The outer circumferential surface of the liquid storage tube <NUM> is protruded to provide with a limiting portion (not labelled). The upper end of the connecting sleeve <NUM> is engaged with the limiting portion. When the connecting sleeve <NUM> is installed in place, the limiting portion abuts against the upper end of the connecting sleeve <NUM> to provide a limiting function to the installation of the liquid storage tube <NUM>. In this embodiment, the lower end of the limiting portion is set in a wavy curved shape, to provide a positioning function for the liquid storage tube <NUM> to prevent the liquid storage tube <NUM> and the connecting sleeve <NUM> from rotating with each other. The locking protrusion is provided at the lower end of the limiting portion, and the locking groove is provided on the inner wall of the connecting sleeve <NUM>.

The connecting member <NUM> is installed in the lower end of the connecting sleeve <NUM> by interference fit, and abuts against the end cover <NUM>. The connecting member <NUM> has a substantially plate-like structure. The lower end of the connecting member <NUM> is threadedly fitted with the upper end of the power supply device <NUM>, so as to achieve a fixed connection relationship between the connecting assembly <NUM> and the power supply device <NUM>. It can be understood that, in other embodiments not shown, the connecting member <NUM> and the power supply device <NUM> may also be detachably connected by snapping connection, plugging connection, or magnetic connection, which is not limited here.

Please refer to <FIG> again, the lower end surface of the connecting member <NUM> is recessed upward to form a receiving groove <NUM>. The atomizing assembly <NUM> is received in the receiving groove <NUM>. Please refer to <FIG> again, the upper end surface of the connecting member <NUM> is provided with two oppositely arranged through holes <NUM> corresponding to the two connecting tubes <NUM>. Each through hole <NUM> constitutes a liquid outlet through hole in communication with the liquid storage chamber <NUM>. The lower end of the connecting tube <NUM> passes through the through hole <NUM> and then abuts against the atomizing assembly <NUM>, so that the e-liquid in the liquid storage chamber <NUM> can flow into the atomizing assembly <NUM> through the connecting tubes <NUM> to be heated to generate smoke. In order to avoid the leakage of e-liquid, a sealing ring <NUM> is sandwiched between the inner wall of the through hole <NUM> and the outer wall of the connecting tube <NUM>. It can be understood that, the material of the sealing ring <NUM> includes, but is not limited to, silicone or rubber.

In addition, please refer to <FIG> again, the connecting member <NUM> is provided with a U-shaped connecting passage <NUM> therein. One end of the connecting passage <NUM> is in communication with the air inlet passage <NUM>, and the other end of the connecting passage <NUM> is in communication with the air outlet passage <NUM>. The lower end of the connecting passage <NUM> is in communication with the receiving groove <NUM>. A portion of the air inlet passage <NUM> and a portion of the air outlet passage <NUM> are blocked by the part of the connecting member <NUM> that is surrounded by the connecting passage <NUM>, so as to block the tiny e-liquid particles splashed during atomization, avoid scalding the user, and improve the safety of use. In order to facilitate air flowing through the end cover <NUM>, the end cover <NUM> is provided with a first through hole <NUM> and a second through hole <NUM> therein, wherein the first through hole <NUM> is in communication with one end of the connecting passage <NUM> and the air inlet passage <NUM>, and the second through hole <NUM> is in communication with the other end of the connecting passage <NUM> and the air outlet passage <NUM>. The direction indicated by the dashed arrows in <FIG> is the airflow direction.

Please refer to <FIG>, the atomizing assembly <NUM> includes an atomizing base <NUM>, a liquid absorbing member <NUM> received in the atomizing base <NUM>, and a heating member <NUM> installed on the atomizing base <NUM>.

The atomizing base <NUM> is substantially in the shape of a circular plate. The upper end surface of the atomizing base <NUM> is recessed downward to form a mounting groove <NUM>. The liquid absorbing member <NUM> is received in the mounting groove <NUM>. The heating member <NUM> is located above the mounting groove <NUM> of the atomizing base <NUM> corresponding to the liquid absorbing member <NUM>, and the heating member <NUM> presses and fixes the liquid absorbing member <NUM> in the mounting groove <NUM>. The atomizing base <NUM> is provided with mounting holes <NUM> on opposite sides of the mounting groove <NUM>. Two pins <NUM> are connected to two ends of the heating member <NUM>, each pin <NUM> corresponds to one mounting hole <NUM>. The two pins <NUM> pass through the corresponding mounting holes <NUM>, and then are bent in facing directions and attached to the atomizing base <NUM>. At this time, due to the bending of the pins <NUM>, the heating member <NUM> is not easy to be drawn out, so that the heating member <NUM> is fixed on the atomizing base <NUM>, to effectively prevent the heating member <NUM> from loosening, and the operation is simple and convenient to use. Also, it is ensured that the liquid absorbing member <NUM> and the heating member <NUM> are in contact with each other closely, and the atomizing efficiency of the e-liquid is improved. It can be understood that, in other embodiments not shown, there may be only one mounting hole <NUM>; correspondingly, there is only one pin <NUM>. At this time, the one pin <NUM> of the heating member <NUM> passes through the mounting hole <NUM> and then is bent, which can also fix the heating member <NUM>.

In one of the embodiments not shown, the lower end of the connecting tube <NUM> is pre-sealed with a sealing member (not shown). In other words, before the liquid storage assembly <NUM> and the atomizing assembly <NUM> are installed together, the e-liquid in the liquid storage assembly <NUM> is isolated from the outside world. The sealing member can be an aluminum foil or other similar metal film, or plastic film. After the liquid storage assembly <NUM> is installed onto the atomizing assembly <NUM>, a piercing member (not shown) provided on the atomizing base <NUM> pierces the sealing member to destroy the sealing effect, so as to introduce the e-liquid in the liquid storage assembly <NUM> into the atomizing assembly <NUM>, which is convenient to continuously heat and atomize the e-liquid after the atomizing assembly <NUM> is energized and activated. After the e-liquid in the liquid storage assembly <NUM> is used up, the liquid storage assembly <NUM> can be directly removed from the atomizing assembly <NUM>, without the need to discard the electronic cigarette as a whole, which reduces the user's use cost.

It can be understood that, in other embodiments not shown, the piercing member is installed in the liquid outlet through hole. After the liquid storage assembly <NUM> and the connecting assembly <NUM> are installed in place, the connecting tube <NUM> serves as the piercing member to pierce the sealing member, so that the e-liquid can flow out of the liquid storage chamber <NUM>.

In use, the power supply device <NUM> supplies power to the heating member <NUM>, and the heating member <NUM> heats the e-liquid absorbed on the liquid absorbing member <NUM> after the heating member <NUM> is energized, so that the e-liquid generates smoke. In addition, the heating member <NUM> is provided with at least one smoke outlet hole (not shown). The smoke outlet hole is a through hole and is in communication with the connecting passage <NUM> to facilitate smoke to flow into the user's mouth after passing through the smoke outlet hole. When the user needs to replace the heating member <NUM> and the liquid absorbing member <NUM>, the user only needs to straighten the pin <NUM>, then pull out the heating member <NUM>, and further take out the liquid absorbing member <NUM> from the mounting groove <NUM>.

Specifically, the lower end of the connecting tube <NUM> passes through the through hole <NUM> of the connecting member <NUM> to abut against the liquid absorbing member <NUM>, thereby ensuring that the e-liquid can be absorbed by the liquid absorbing member <NUM> in time, and the speed of absorbing the e-liquid is increased, and the leakage of the e-liquid is avoided. The direction indicated by the solid arrows in <FIG> is the flow direction of the e-liquid.

The liquid absorbing member <NUM> has the function of absorbing e-liquid. The liquid absorbing member <NUM> is a porous liquid absorbing member. The liquid absorbing member <NUM> can be made of one, two or a combination of cotton, porous ceramic, fiber rope, foamed metal, and foamed graphite. In this embodiment, the liquid absorbing member <NUM> is cotton. The heating member <NUM> has a sheet-like structure, and the heating member <NUM> is a heat-generating member that can be energized to generate heat. In this embodiment, the heating member <NUM> is a metal heating sheet, the heating member <NUM> and the pins <NUM> are integrally formed.

In this embodiment, the material of the atomizing base <NUM> is liquid-absorbing ceramic, which has liquid-absorbing ability and can absorb and store part of the e-liquid to effectively prevent dry burning. In this case, the atomizing base <NUM> not only has the function of installing the liquid absorbing member <NUM>, but also has the function of liquid absorption. It can be understood that, when the atomizing base <NUM> is made of liquid-absorbing ceramic, since the pins <NUM> are attached to the atomizing base <NUM>, the pins <NUM> can heat the e-liquid absorbed in the liquid-absorbing ceramic, thereby further improving the atomizing efficiency.

The cartridge connecting seat <NUM> is electrically connected to the other of the positive and negative electrodes of the battery <NUM>. Specifically, the connecting member <NUM> is detachably connected to the cartridge connecting seat <NUM>. In this embodiment, the connecting member <NUM> is connected to the cartridge connecting seat <NUM> by threads. It can be understood that, in other embodiments not shown, the connecting member <NUM> and the cartridge connecting seat <NUM> can also be detachably connected by means of snapping, plugging, or magnetic connection, which is not limited here. When the connecting assembly <NUM>, the atomizing assembly <NUM> and the power supply device <NUM> are installed in place, the atomizing assembly <NUM> is at least partially received in the space between the lower end of the connecting member <NUM> and the upper end of the cartridge connecting seat <NUM>, one pin <NUM> of the heating member <NUM> is in contact with and electrically connected to the first electrode <NUM>, the other pin <NUM> of the heating member <NUM> is in contact with and electrically connected to the cartridge connecting seat <NUM>, so that the heating member <NUM> is electrically connected to the power supply device <NUM>.

Further, it is convenient to disassemble and replace the liquid absorbing member <NUM> and the heating member <NUM> of the atomizing assembly <NUM> individually, which reduces material waste and saves costs. In addition, after the e-liquid in the liquid storage member <NUM> is used up, the user can drop e-liquid onto the liquid absorbing member <NUM> after the liquid storage member <NUM> is pulled out, so that the electronic cigarette <NUM> can be used continuously to realize the functions of a liquid storage type electronic cigarette and a dripping type electronic cigarette respectively, and the user experience is improved.
