Abstract

An electronic cigarette with an atomizing core having multiple atomizing assemblies arranged in parallel is provided. An atomizing seat of the atomizing core is provided with multiple accommodating grooves for accommodating the electric heating wires, and the electric heating wires are spaced from each other with a space interval, which solves a problem that the smoke generated by the electric heating wire cannot be delivered by the airflow in time when the liquid guiding rope is positioned between the electric heating wires and the amount of the smoke is reduced. Each of the electric heating assemblies may be mounted directly from the open end of the respective accommodating grooves, which simplifies the installation and the production process.

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.
  • The atomizing sleeve is sleeved on the accommodating groove wall, and the accommodating groove wall is provided with a stepped portion for defining the connection position of the atomizing sleeve and the accommodating groove wall. 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.

  • DETAILED DESCRIPTION
  • In order to make the purposes, features, and advantage of the present application more apparent and easy to understand, the technical solutions in the embodiments of the present application will be described clearly and completely hereinafter in conjunction with the drawings in the embodiments of the present application. 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 to FIG. 1 in conjunction with FIG. 2 and FIG. 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 assembly 11, an atomizing core 12, and a connecting sleeve 13.
  • The suction nozzle assembly 11 is provided with a liquid storage sleeve 25, an air pipe 24 arranged in the liquid storage sleeve 25 in an axial direction of the liquid storage sleeve 25, and a suction nozzle 21 arranged at an end of the liquid storage sleeve 25. A liquid storage chamber 23 for storing the cigarette liquid is defined by the liquid storage sleeve 25. An air channel 22 allowing airflow to flow to the suction nozzle is defined by the air pipe 24.
  • Two ends of the connecting sleeve 13 may be detachably connected to the suction nozzle assembly 11 and the battery rod, respectively.
  • Two ends of the atomizing core 12 may be detachably connected to the connecting sleeve 13 and the air pipe 24, respectively. The atomizing core 12 and the air pipe 24 are elastically abutted against each other or are insertedly connected, thus, the atomizing core 12 is fixed between the suction nozzle assembly 11 and the connecting sleeve 13, and the atomizing core 12 is arranged in the liquid storage chamber 23, and is hermetically connected to the air pipe 24.
  • It will be appreciated that, the suction nozzle assembly 11 may not only allow the user to smoke, but also store the cigarette liquid inside the liquid storage chamber 23, thereby reducing the length of the electronic cigarette, and facilitate carrying the electronic cigarette. The suction nozzle assembly 11 may be detachably connected to the connecting sleeve 13, and the atomizing core 12 is fixed between the suction nozzle assembly 11 and the connecting sleeve 13. When the cigarette liquid in the liquid storage chamber 23 of the suction nozzle assembly 11 is used up, the connecting sleeve 13 may be removed and the cigarette liquid can be filled into the liquid storage chamber 23, which can increase the service life of the electronic cigarette. Further, if the atomizing core 12 is damaged, the atomizing core 12 may be removed to facilitate replacement.
  • Reference is made to FIG. 5 in conjunction with FIG. 6. The atomizing core is provided with an atomizing sleeve 31, an atomizing seat 32, and an atomizing assembly. The atomizing assembly includes at least two electric heating assemblies 34 for atomizing the cigarette liquid. Each of the electric heating assemblies 34 is provided with a liquid guiding wick 52 and an electric heating wire 51 winding around the liquid guiding wick 52. The atomizing seat 32 is provided with multiple accommodating grooves 33, and each accommodating groove 33 has one end open and is provided for accommodating the respective electric heating assembly 34. The multiple accommodating grooves 33 allow all of the electric heating assemblies 34 to be arranged in parallel in a radial direction of the electronic cigarette and to be spaced from each other with a space interval. The electric heating assemblies 34 may be located at the same radial position on the atomizing seat 32. Two ends of the liquid guiding wick 52 of each electric heating assembly 34 extend out of the respective accommodating grooves 33 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 the electric heating wire 51 to be atomized. The width of each accommodating groove 33 is smaller than the diameter of the liquid guiding wick 52, thus, the liquid guiding wick 52 can be clamped by the respective accommodating grooves 33 tightly, to prevent the liquid guiding wick 52 from absorbing an excessive amount of the cigarette liquid which may reduce the amount of smoke.
  • The atomizing sleeve 31 is sleeved on an accommodating groove wall, and the accommodating groove wall is provided with a stepped portion for defining a connection position of the atomizing sleeve 31 and the accommodating groove wall. When the atomizing sleeve 31 is fixed at the connection portion of the accommodating groove wall, the atomizing sleeve 31 abuts against the liquid guiding wicks 52, thus, the abutting portion of the liquid guiding wicks 52 can have a sealing effect to prevent the cigarette liquid in the liquid storage chamber 23 from flowing into an atomizing chamber 40.
  • It can be known that, the atomizing assembly of the electronic cigarette is provided with multiple electric heating assemblies 34 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 the electric heating assemblies 34 are damaged, the electronic cigarette can still operate normally as long as there is still one heat generating device 34 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 one electric heating assembly 34.
  • The multiple electric heating assemblies 34 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 multiple electric heating assemblies 34 due to heating, and it also omits the glass fiber ropes disposed among the multiple electric heating assemblies 34, which simplifies the production process and lowers the cost.
  • The multiple electric heating assemblies 34 are arranged in parallel in the radial direction of the electronic cigarette, which avoids a problem of the atomizing seat 32 occupying a greater length of the electronic cigarette caused by positioning the electric heating wires 51 in the cross groove of the atomizing seat 32. The electric heating assemblies 34 arranged in parallel can avoid a problem of the lower electric heating wires 51 heating the upper electric heating wires 51 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 the liquid guiding wick 52 has a good elasticity and the width of the accommodating groove is smaller than the diameter of the liquid guiding wick 52, the accommodating grooves can clamp the liquid guiding wick 52, to prevent the liquid guiding wick 52 from falling out of the accommodating grooves 33. The sectional area of the clamped portion of the liquid guiding wick 52 is reduced, which can control the amount of the cigarette liquid stored in the liquid guiding wick 52. Thus, the liquid guiding wick 52 will not absorb excessive cigarette liquid, which further ensures that the electric heating wires 51 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.
  • The atomizing sleeve 31 is sleeved on the accommodating groove wall, and the accommodating groove wall is provided with a stepped portion for defining the connection position of the atomizing sleeve 31 and the accommodating groove wall. When the atomizing sleeve 31 is fixed at the connection position of the accommodating groove wall, the atomizing sleeve 31 abuts against the liquid guiding wicks 52. Since the liquid guiding wick 51 has a good elasticity, the abutting portion of the liquid guiding wick 52 can have a sealing effect to prevent the cigarette liquid in the liquid storage chamber 23 from flowing into the atomizing chamber 40.
  • In this embodiment, the accommodating groove wall is provided with an extending section 321 and a retaining section 322. A stepped portion is provided at the connection portion of the extending section 321 and the retaining section 322. The stepped portion is provided for defining the connection position of the atomizing sleeve 31 and the accommodating groove wall 39 of the atomizing seat. The thickness of the accommodating groove wall at the extending section 321 is smaller than the thickness of the accommodating groove wall at the retaining section 322, which facilitates insertedly connecting the atomizing sleeve 31 to the atomizing seat 32. 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 the atomizing sleeve 31. The boss and the groove may cooperate with each other to fix the atomizing sleeve 31 onto the atomizing seat 32. Certainly, other fixing manners can be employed, and the specific manner is not limited here.
  • In this embodiment, referring to FIG. 6, the atomizing core 12 is provided with an atomizing cover 35 which covers the atomizing sleeve 31 and abuts against the air pipe. The atomizing cover 35 is provided with a through hole for communicating the air channel 22 with the atomizing core 12.
  • The atomizing cover 35 is provided with an accommodating chamber, and an abutting portion for hermetically connecting the atomizing cover 35 to the air pipe 24, and a sealing ring 36 for preventing the cigarette liquid in the liquid storage chamber 23 from flowing into the air channel 22 and the atomizing core 12 are provided in the accommodating chamber.
  • In this embodiment, the air pipe 24 of the air channel is inserted into the accommodating chamber of the atomizing cover 35 to be connected to the atomizing cover 35, and the sealing ring 36 is sleeved on the outer wall of the air pipe 24 of the air channel to seal the abutting portion of the atomizing cover 35 and the air pipe 24.
  • In this embodiment, referring to FIG. 3, an air passage 132 is provided inside the connecting sleeve 13. The outer wall of the connecting sleeve is provided with an air hole 131 for communicating with the external air. The air hole 131 is in communication with the air passage 132.
  • The atomizing chamber 40 of the atomizing seat is in communication with the air passage 132 of the connecting sleeve. Thus, when a user smokes the electronic cigarette, the airflow enters via the air hole and passes through the air passage 132, 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 the atomizing chamber 40 and the air channel 22.
  • It will be appreciated that, when the user is smoking, the airflow enters via the air hole 131, and then enters into the mouth of the user by passing through the air passage 132, the atomizer chamber 40 of the atomizing seat and the air channel 22.
  • In this embodiment, referring to FIG. 3 and FIG. 6, the atomizing seat 32 is provided with a second threaded portion 28 for being threadedly connected to the connecting sleeve 13.
  • The connecting sleeve 13 is provided with a first threaded portion 27 which cooperates with the second threaded portion 28. The first threaded portion 27 is provided for detachably connecting the atomizing seat 32 to the connecting sleeve 13 by means of screw threads.
  • The atomizing core 12 is provided with an electrode 37 which is electrically connected to the electric heating wires 51. The atomizing seat 32 and the connecting sleeve 32 are each made of conductive material. The atomizing seat 32 is electrically connected to the electric heating wires 51. An insulating ring 38 is provided between the atomizing seat 32 and the electrode 37 to insulate the electrode 37 from the atomizing seat 32. The insulating ring 38 and the atomizing seat 32 are connected by snap fit, and the electrode 37 is snapped into the insulating ring 38 to electrically connect the atomizing seat 32 and the electrode 37 to the battery rod. Thus, the battery rod can provide power to each of the heating wires 51 for atomizing the cigarette liquid.
  • Specifically, the connection portion of the atomizing seat is connected to the insulating ring by snap fit, and the electrode 37 is snapped into the insulating ring 38. With this structure, an outer electrode is omitted. The connection portion of the atomizing seat 32 and the connecting sleeve 13 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, the entire atomizing seat 39 is made of metallic material such as copper or iron. The liquid guiding wick 52 may employ a glass fiber rope. The electric heating wire 51 may be made of nickel-chrome alloy.
  • In this embodiment, the suction nozzle assembly 11 is threadedly connected to the connecting sleeve 13. Certainly, the suction nozzle assembly and the connecting sleeve can also be connected by snap fit or magnet connection.
  • In this embodiment, the electronic cigarette further includes a decorating part 30 made of metal. The decorating part 30 may be detachably connected to the connecting sleeve 13, and the decorating part 30 wraps the connection portion of the connecting sleeve 13 and the suction nozzle assembly 11.
  • A concave portion is provided on the liquid storage sleeve 25 at a position close to the connection portion of the connecting sleeve 13 and the suction nozzle assembly 11. The thickness of the liquid storage sleeve at the concave portion is smaller than the wall thickness of the liquid storage sleeve. When the decorating part 30 wraps the connection portion of the connecting sleeve 13 and the suction nozzle assembly 11, the decorating part 30 is accommodated in the concave portion, thus, the appearance of the electronic cigarette is smooth and aesthetic.
  • In this embodiment, the liquid storage sleeve 25 is a transparent body made of plastic cement, which facilitates observing the remaining amount of the cigarette liquid in the liquid storage sleeve 25 to fill the cigarette liquid in time when the cigarette liquid is used up. The decorating part 30 is made of metal, thus the reliability of the connection between the decorating part 30 and the connecting sleeve 13 is improved, which also prolongs the service life of the electronic cigarette.
