The sectional area of the clamped portion of the liquid guiding wick is reduced, which can control the amount of the cigarette liquid stored in the liquid guiding wick. Thus, the liquid guiding wick will not absorb excessive cigarette liquid, which further ensures that the electric heating wires can sufficiently atomize the cigarette liquid to generate a large amount of smoke when the user smokes the electronic cigarette. With this arrangement, a problem of insufficient atomization due to an excessive supply of the cigarette liquid is avoided without increasing the production process, which would otherwise causes a small amount of the smoke.

When the atomizing sleeve is fixed at the connection position of the accommodating groove wall, the atomizing sleeve abuts against the liquid guiding wicks. Since the liquid guiding wick has a good elasticity, the abutting portion of the liquid guiding wick can have a sealing effect to prevent the cigarette liquid in the liquid storage chamber from flowing into the atomizing chamber. In addition, such arrangement may better avoid problems of the liquid guiding wick being overly pressed or liquid leakage due to gaps generated around the liquid guiding wick when the atomizing sleeve is not mounted in place, thereby facilitating the installation and improving the production efficiency.

Apparently, the described embodiments are only a part of the embodiments of the present application, rather than all embodiments. Based on the embodiments in the present application, all of other embodiments, made by the person skilled in the art without any creative efforts, fall into the scope of the present application.
• An electronic cigarette is provided according to this embodiment. Reference is made toFIG. 1 in conjunction withFIG. 2 andFIG. 4. The electronic cigarette includes an atomizer for atomizing cigarette liquid and a battery rod (not shown) for powering the atomizer. The atomizer includes a suction nozzle assembly11, anatomizing core12, and a connectingsleeve13.
• The suction nozzle assembly11 is provided with aliquid storage sleeve25, anair pipe24 arranged in theliquid storage sleeve25 in an axial direction of theliquid storage sleeve25, and asuction nozzle21 arranged at an end of theliquid storage sleeve25. Aliquid storage chamber23 for storing the cigarette liquid is defined by theliquid storage sleeve25. Anair channel22 allowing airflow to flow to the suction nozzle is defined by theair pipe24.
• Two ends of the connectingsleeve13 may be detachably connected to the suction nozzle assembly11 and the battery rod, respectively.
• Two ends of theatomizing core12 may be detachably connected to the connectingsleeve13 and theair pipe24, respectively. Theatomizing core12 and theair pipe24 are elastically abutted against each other or are insertedly connected, thus, theatomizing core12 is fixed between the suction nozzle assembly11 and the connectingsleeve13, and theatomizing core12 is arranged in theliquid storage chamber23, and is hermetically connected to theair pipe24.
• It will be appreciated that, the suction nozzle assembly11 may not only allow the user to smoke, but also store the cigarette liquid inside theliquid storage chamber23, thereby reducing the length of the electronic cigarette, and facilitate carrying the electronic cigarette. The suction nozzle assembly11 may be detachably connected to the connectingsleeve13, and theatomizing core12 is fixed between the suction nozzle assembly11 and the connectingsleeve13. When the cigarette liquid in theliquid storage chamber23 of the suction nozzle assembly11 is used up, the connectingsleeve13 may be removed and the cigarette liquid can be filled into theliquid storage chamber23, which can increase the service life of the electronic cigarette. Further, if theatomizing core12 is damaged, theatomizing core12 may be removed to facilitate replacement.
• Reference is made toFIG. 5 in conjunction withFIG. 6. The atomizing core is provided with anatomizing sleeve31, an atomizingseat32, and an atomizing assembly. The atomizing assembly includes at least twoelectric heating assemblies34 for atomizing the cigarette liquid. Each of theelectric heating assemblies34 is provided with aliquid guiding wick52 and anelectric heating wire51 winding around theliquid guiding wick52. The atomizingseat32 is provided with multipleaccommodating grooves33, and eachaccommodating groove33 has one end open and is provided for accommodating the respectiveelectric heating assembly34. The multipleaccommodating grooves33 allow all of theelectric heating assemblies34 to be arranged in parallel in a radial direction of the electronic cigarette and to be spaced from each other with a space interval. Theelectric heating assemblies34 may be located at the same radial position on the atomizingseat32. Two ends of theliquid guiding wick52 of eachelectric heating assembly34 extend out of the respectiveaccommodating grooves33 and are in contact with the cigarette liquid in the liquid storage chamber to absorb and store the cigarette liquid, and to supply the cigarette liquid to theelectric heating wire51 to be atomized. The width of eachaccommodating groove33 is smaller than the diameter of theliquid guiding wick52, thus, theliquid guiding wick52 can be clamped by the respectiveaccommodating grooves33 tightly, to prevent theliquid guiding wick52 from absorbing an excessive amount of the cigarette liquid which may reduce the amount of smoke.
• Theatomizing sleeve31 is sleeved on an accommodating groove wall, and the accommodating groove wall is provided with a stepped portion for defining a connection position of theatomizing sleeve31 and the accommodating groove wall. When theatomizing sleeve31 is fixed at the connection portion of the accommodating groove wall, theatomizing sleeve31 abuts against theliquid guiding wicks52, thus, the abutting portion of theliquid guiding wicks52 can have a sealing effect to prevent the cigarette liquid in theliquid storage chamber23 from flowing into anatomizing chamber40.
• It can be known that, the atomizing assembly of the electronic cigarette is provided with multipleelectric heating assemblies34 which can atomize the cigarette liquid at the same time to generate smoke, thereby increasing the amount of the smoke generated by the electronic cigarette and bringing an excellent smoking experience for the user. In the case that one or several of theelectric heating assemblies34 are damaged, the electronic cigarette can still operate normally as long as there is still oneheat generating device34 that can atomize the cigarette liquid normally, thus, the user still can smoke the electronic cigarette, which avoids the disadvantage of the electronic cigarette with only oneelectric heating assembly34.
• The multipleelectric heating assemblies34 in the atomizing assembly of the electronic cigarette are spaced from each other and disposed in the axial direction of the electronic cigarette. Thus, it avoids a short circuit among the multipleelectric heating assemblies34 due to heating, and it also omits the glass fiber ropes disposed among the multipleelectric heating assemblies34, which simplifies the production process and lowers the cost.
• The multipleelectric heating assemblies34 are arranged in parallel in the radial direction of the electronic cigarette, which avoids a problem of the atomizingseat32 occupying a greater length of the electronic cigarette caused by positioning theelectric heating wires51 in the cross groove of the atomizingseat32. Theelectric heating assemblies34 arranged in parallel can avoid a problem of the lowerelectric heating wires51 heating the upperelectric heating wires51 when the electric heating wires are arranged in the shape of a cross, and also avoid a short circuit generated in the case that the upper heating wire is bent and comes into contact with the lower heating wire when the electronic wire of the upper heating wire is pulled.
• Since theliquid guiding wick52 has a good elasticity and the width of the accommodating groove is smaller than the diameter of theliquid guiding wick52, the accommodating grooves can clamp theliquid guiding wick52, to prevent theliquid guiding wick52 from falling out of theaccommodating grooves33. The sectional area of the clamped portion of theliquid guiding wick52 is reduced, which can control the amount of the cigarette liquid stored in theliquid guiding wick52. Thus, theliquid guiding wick52 will not absorb excessive cigarette liquid, which further ensures that theelectric heating wires51 can sufficiently atomize the cigarette liquid to generate a large amount of smoke when the user smokes the electronic cigarette. With this arrangement, a problem of insufficient atomization due to an excessive supply of the cigarette liquid is avoided without increasing the production process, which would otherwise causes a small amount of the smoke.
• Theatomizing sleeve31 is sleeved on the accommodating groove wall, and the accommodating groove wall is provided with a stepped portion for defining the connection position of theatomizing sleeve31 and the accommodating groove wall. When theatomizing sleeve31 is fixed at the connection position of the accommodating groove wall, theatomizing sleeve31 abuts against theliquid guiding wicks52. Since theliquid guiding wick51 has a good elasticity, the abutting portion of theliquid guiding wick52 can have a sealing effect to prevent the cigarette liquid in theliquid storage chamber23 from flowing into theatomizing chamber40.
• In this embodiment, the accommodating groove wall is provided with an extending section321 and aretaining section322. A stepped portion is provided at the connection portion of the extending section321 and theretaining section322. The stepped portion is provided for defining the connection position of theatomizing sleeve31 and theaccommodating groove wall39 of the atomizing seat. The thickness of the accommodating groove wall at the extending section321 is smaller than the thickness of the accommodating groove wall at theretaining section322, which facilitates insertedly connecting theatomizing sleeve31 to the atomizingseat32. The stepped portion may include a boss protruding out of the surface of the accommodating groove wall, and a groove configured to cooperate with the boss of the stepped portion is provided on the inner wall of theatomizing sleeve31. The boss and the groove may cooperate with each other to fix theatomizing sleeve31 onto the atomizingseat32. Certainly, other fixing manners can be employed, and the specific manner is not limited here.

• In this embodiment, theair pipe24 of the air channel is inserted into the accommodating chamber of theatomizing cover35 to be connected to theatomizing cover35, and the sealingring36 is sleeved on the outer wall of theair pipe24 of the air channel to seal the abutting portion of theatomizing cover35 and theair pipe24.
• In this embodiment, referring toFIG. 3, anair passage132 is provided inside the connectingsleeve13. The outer wall of the connecting sleeve is provided with anair hole131 for communicating with the external air. Theair hole131 is in communication with theair passage132.
• Theatomizing chamber40 of the atomizing seat is in communication with theair passage132 of the connecting sleeve. Thus, when a user smokes the electronic cigarette, the airflow enters via the air hole and passes through theair passage132, the atomizing assembly atomizes the cigarette liquid to generate smoke, and then the smoke is sucked into the mouth via the suction nozzle by passing through theatomizing chamber40 and theair channel22.
• It will be appreciated that, when the user is smoking, the airflow enters via theair hole131, and then enters into the mouth of the user by passing through theair passage132, theatomizer chamber40 of the atomizing seat and theair channel22.
• In this embodiment, referring toFIG. 3 andFIG. 6, the atomizingseat32 is provided with a second threadedportion28 for being threadedly connected to the connectingsleeve13.
• The connectingsleeve13 is provided with a first threadedportion27 which cooperates with the second threadedportion28. The first threadedportion27 is provided for detachably connecting the atomizingseat32 to the connectingsleeve13 by means of screw threads.

• Specifically, the connection portion of the atomizing seat is connected to the insulating ring by snap fit, and theelectrode37 is snapped into the insulatingring38. With this structure, an outer electrode is omitted. The connection portion of the atomizingseat32 and the connectingsleeve13 is made of conductive material to replace the outer electrode. Thus, compared to the conventional electronic cigarette, the present application saves a component, simplifies the process, and improves the production efficiency.
• In this embodiment, the electric heating wires are electrically connected in parallel, and then the two ends of each of the electric heating wires are electrically connected to the connection portion of the atomizing seat and the electrode, respectively. Specifically, firstly, the electric heating wires are electrically connected in parallel by welding the electric heating wires to the conductive wires which are connected to the connection portion or the electrode. Then, the electric heating wires connected in parallel are mounted into the accommodating groove of the atomizing seat. Thus, the installation and the process are simplified.
• In this embodiment, theentire atomizing seat39 is made of metallic material such as copper or iron. Theliquid guiding wick52 may employ a glass fiber rope. Theelectric heating wire51 may be made of nickel-chrome alloy.
