Description:
TECHNICAL FIELD 
       [0001]    The present disclosure relates to the field of electronic cigarette technology, and in particular to an atomizer and an electronic cigarette which can prevent a user from smoking non-atomized e-liquid and can make the user feel more comfortable when smoking. 
       BACKGROUND 
       [0002]    Electronic cigarette is a new kind of electronic product. It has the same appearance and flavor as the traditional cigarette, but is more healthy and environment-friendly comparing with the traditional cigarette. The electronic cigarette atomizes e-liquid containing nicotine and essence into particles by an atomizer for output. Tar and other harmful ingredients contained in the traditional cigarette are not contained in the electronic cigarette, and second-hand smoking will not be produced. 
         [0003]    The electronic cigarette in the prior art usually includes an atomizing assembly configured to atomizing e-liquid and a battery assembly configured to supply power to the atomizing assembly. The atomizing assembly and the battery assembly are positioned coaxially and connected to each other. A e-liquid storage sleeve configured to store the e-liquid is provided at the end of the atomizing assembly having an atomizing device. The atomizing device includes a heating wire configured to atomizing e-liquid. The end of the e-liquid storage sleeve which is away from the atomizing assembly is an open end, a suction nozzle is connected to the open end for a user to smoke, a smoke vent, which is in the same line as the smoke channel in the e-liquid storage sleeve and serves as a smoke channel, is provided in the center of the suction nozzle. The diameter of the smoke vent is usually set as 2 mm to 3 mm for smooth smoking. In the prior art, the e-liquid storage sleeve stores e-liquid, and is connected to the atomizing assembly, so as to make the heating wire of the atomizing assembly atomize the e-liquid in the e-liquid storage sleeve. The smoke formed by atomized e-liquid enters into the mouth of a smoker through the smoke channels in the e-liquid storage sleeve and the suction nozzle. 
         [0004]    However, in the electronic cigarette described above, the smoke vent in the suction nozzle served as the smoke channel is in the same line as the smoke channel in the e-liquid storage sleeve. In the process of smoking, part of the smoke in the smoke channel of the atomizing assembly condenses into large-grained e-liquid and enters the mouth of the user with an air flow through the smoke vent, so that the user smoke the tobacco tar. In addition, in a case that the smoke emits directly from a large smoke vent, the speed of the smoke air flow is fast enough to form a torrent smoke column, which directly impinges the mouth wall of the smoker, so that the smoker usually feels discomfortable, and the user experience is poor.

A part of the condensed e-liquid directly adheres to the inner wall of the smoke channel to avoid emitting, and large-grained smoke is further filtered via the smoke outlet gaps when the smoke emits from the smoke outlet gaps. The probability of taking in condensed e-liquid or large-grained smoke by the user is reduced, thereby enhancing user experience of the electronic cigarette. In addition, since the smoke outlet gaps extend from the center of the end surface of the suction nozzle cover to the peripheries of the end surface of the suction nozzle cover, the smoke emits from the center to the periphery of the suction nozzle cover. The smoke is decentralized, and emits mildly, so that the smoke is similar to the tobacco smoke. The feel of the smoking is comfortable, the situation that the torrent smoke impinges the mouth of the smoker in the prior art is avoided, and the user experience is further improved.

     DETAILED DESCRIPTION OF THE EMBODIMENTS 
       [0054]    The present disclosure discloses an atomizer and an electronic cigarette which can prevent users from smoking the non-atomized e-liquid and can make the user feel more comfortable when smoking. 
         [0055]    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 disclosure. Apparently, the described embodiments are only a part of rather than all of the embodiments of the present disclosure. Other embodiments obtained by those skilled in the art based on these embodiments of the disclosure without creative work fall within the protection scope of the disclosure. 
         [0056]    Referring to  FIG. 1 , an electronic cigarette according to an embodiment of the present disclosure includes the following. 
         [0057]    In this embodiment, an electronic cigarette  100  includes: 
         [0058]    an electronic cigarette body, sequentially provided with a suction nozzle cover  101 , an atomizing assembly  102  and a battery assembly  103  configured to power the atomizing assembly  102 . 
         [0059]    Inside the atomizing assembly  102 , there are provided with an e-liquid storage space  1021  configured to store e-liquid, an atomizing core  1022  which is configured to atomize the e-liquid and is connected to the e-liquid storage space  1021  and electrically connected to the battery assembly  103 . Specifically, e-liquid storage cotton is provided in the e-liquid storage space  1021 . In the actual implementation, other e-liquid mediums or no e-liquid medium may be provided in the e-liquid storage space, which is not limited herein. In this embodiment, the atomizing core  1022  is specifically a heating wire assembly. In the actual implementation, the atomizing core can also be achieved in another way, such as a heating band or an ultrasonic atomizing assembly, which is not limited herein. In the atomizing assembly  102 , a smoke channel  1023  configured to emit the smoke to the suction nozzle cover  101  is further provided. The smoke channel  1023  is configured to connect the atomizing core  1022  to the suction nozzle cover  101 , and extends along the axis of atomizing assembly  102 . 
         [0060]    Referring to  FIG. 2 , a structural diagram of a suction nozzle cover of an electronic cigarette according to an embodiment of the present disclosure is shown. At least two smoke outlet gaps  1011  interconnected to the smoke channel  1023  are provided on the end surface  1012  of the suction nozzle cover  101 . The smoke outlet gaps  1011  extend from the center of the end surface  1012  of the suction nozzle cover  101  to the periphery of the end surface  1012  of the suction nozzle cover  101 , and the center of the end surface  1012  of the suction nozzle cover  101  is located on the axis of the atomizing assembly  102 . 
         [0061]    The suction nozzle cover  101  covers an end surface of the atomizing assembly  102 . When the user smokes, the e-liquid atomized by the atomizing core  1022  is delivered to suction nozzle cover  101  with air flow through the smoke channel  1023 , and is delivered to the mouth of the user via the smoke outlet gaps  1011 . In the prior art, part of the smoke condenses inside the smoke channel  1023 , and in a case that large air flow is generated by the smoking of the user, the condensed e-liquid will fly to the suction nozzle cover  101  in a straight line along the smoke channel  1023  at the force of the air flow, so that the user smokes the non-atomized e-liquid. 
         [0062]    In the present embodiment, at least two smoke outlet gaps  1011  are provided on the end surface of the suction nozzle cover  101 , so that the force generated when the user smokes is dispersed onto the smoke outlet gaps  1011 . Since the area of each of the smoke outlet gaps  1011  is small, the speed of the air flow generated in the smoke channel when the user smokes can be reduced, and the force applied on the condensed e-liquid in the smoke channel is effectively reduced. A part of the condensed e-liquid directly adheres to the inner wall of the smoke channel  1023  to avoid emitting, and large-grained smoke is further filtered via the smoke outlet gaps  1011  when the smoke emits from the smoke outlet gaps  1011 . The probability of taking in condensed e-liquid or large-grained smoke by the user is reduced, thereby enhancing user experience of the electronic cigarette. In addition, since the smoke outlet gaps  1011  extend from the center of the end surface of the suction nozzle cover  101  to the peripheries of the end surface of the suction nozzle cover  101 , the smoke emits from the center to the periphery of the suction nozzle cover  101 . The smoke is decentralized, and emits mildly, so that the smoke is similar to the tobacco smoke. The feel of the smoking is comfortable, the situation that the torrent smoke impinges the mouth of the smoker in the prior art is avoided, and the user experience is further improved. 
         [0063]    In this embodiment, since the condensed e-liquid is drop-shaped, the volume is large. Thus, in this embodiment, the width of the arc smoke outlet gaps  1011  of the suction nozzle cover  101  is, preferably, less than or equal to 0.7 mm, and more preferably, 0.3 mm. In this manner, in a case that a small part of e-liquid flies to the smoke outlet gaps  1011  at the force of the air flow, it cannot enter the mouth of the user because of the restriction of area of the smoke outlet gaps  1011 , and then flows back to the smoke channel  1023  under gravity, or the user can toss the e-liquid out from the smoke outlet gaps  1011 . 
         [0064]    In the present embodiment, preferably, an elastic layer is provided on the side wall of the suction nozzle cover  101  conterminous to the atomizing assembly  102  (not shown in the drawings). The joint sealing between the suction nozzle cover and atomizing assembly may be achieved, and the leakage of the e-liquid from the joint of the suction nozzle cover and the atomizing assembly is avoided. 
         [0065]    The smoke outlet gaps  1011  may be arranged on the suction nozzle cover  101  in multiple ways. Specifically, in the embodiment shown in  FIG. 2 , the suction nozzle cover  101  is a hollow tube. The end of the suction nozzle cover  101  facing the atomizing assembly  102  is completely open, and is connected to the atomizing assembly  102 . The end of the suction nozzle cover  101  back to the atomizing assembly  102  is provided with the end surface  1012 , and the smoke outlet gaps  1011  are provided on the end surface  1012 . In this embodiment, eight smoke outlet gaps  1011  are provided on the suction nozzle cover  101 , which are in a shape of “Union jack” on the end surface  1012  of the suction nozzle cover  101 . In the actual implementation, the smoke outlet gaps  1011  provided on the suction nozzle cover  101  may be of other numbers, and may be arranged in other shapes on the end surface  1012 , which are not limited herein. In this embodiment, each of the smoke outlet gaps  1011  on the end surface  1012  of the suction nozzle cover  101  is in a shape of a straight line. In the actual implementation, each of the smoke outlet gaps  1011  may be in other shapes. 
         [0066]    Referring to  FIG. 3 , a structural diagram of a suction nozzle cover  101  of an electronic cigarette according to another embodiment of the present disclosure is shown. In this embodiment, the smoke outlet gaps  1011  are different from those shown in  FIG. 2  in that the shapes are arc. 
         [0067]    It should be noted that, each of the smoke outlet gaps  1011  may be in regular circular arc shape, or in other arc shapes, which is not limited herein. Even more, the periphery of each of the smoke outlet gaps may be an arc-like line consisting of multiple straight line segments rather than an arc. 
         [0068]    In this embodiment, the arc-shaped smoke outlet gaps can better prevent non-atomized e-liquid from entering into the mouth of the user. Since the smoke channel extends along the axis of the atomizing assembly, and the center of the end surface of the suction nozzle cover is located on the axis of the atomizing assembly, in a case that non-atomized e-liquid flies with the air flow to the suction nozzle cover  101 , the e-liquid will adhere to the center of the end surface of the suction nozzle cover, and move along the smoke outlet gaps under the force of the air flow. In this embodiment, since each of the smoke outlet gaps  1011  are in an arc shape, the e-liquid will move in a straight line from the center of the end surface of the suction nozzle cover  101  to the periphery of the end surface of the suction nozzle cover due to inertia, so that the e-liquid will gradually deviate from the smoke outlet gaps in the process of moving, thereby avoiding that the e-liquid enters the mouth of the user through the smoke outlet gaps. 
         [0069]    Referring to  FIG. 4 , a structural diagram of a suction nozzle cover  101  of an electronic cigarette according to another embodiment of the present disclosure is shown. In this embodiment, the suction nozzle cover  101  is different from that shown in  FIG. 2  in that, the cross-sectional area of the smoke outlet gaps  1011 , which is perpendicular to the end surface  1012  of the suction nozzle cover  101 , gradually increases from the center of the end surface  1012  of the suction nozzle cover  101  to the periphery of the end surface  1012  of the suction nozzle cover  101 . 
         [0070]    Specifically, in this embodiment, the shape of the opening of the smoke outlet gaps  1011  on the end surface  1012  of the suction nozzle cover  101  is a triangle with the center of the end surface  1012  as an apex angle. In the actual implementation, the smoke outlet gaps  1011  may be in other shapes, for example, a sector with the center of the end surface  1012  as a vertex. The above is exemplary description of shapes of the smoke outlet gaps, and is not a limit. 
         [0071]    In this embodiment, since the cross-sectional area of the smoke outlet gaps, which is perpendicular to the end surface  1012 , gradually increases from the center to the periphery of the end surface  1012 , the amount of smoke which the smoker smokes may be increased in one aspect, and the probability that the non-atomized e-liquid enters into the mouth of the user via the center of the end surface  1012  may be reduced in another aspect. 
         [0072]    Referring to  FIG. 5 , structural diagrams of a suction nozzle cover of an electronic cigarette from two angles of view according to another embodiment of the present disclosure are shown, In this embodiment, the suction nozzle cover is different from that shown in  FIG. 4  in that, a circular truncated cone  501  is provided on the end surface  1012  of the suction nozzle cover  101  on the side facing the atomizing assembly  102 , the circular truncated cone  501  includes a upper surface  502  and a lower surface which parallel to each other, and the upper surface  502  is smaller than the lower surface. 
         [0073]    The center axis of the circular truncated cone  501  passes through the center of the end surface  1012 , the upper surface  502  of the circular truncated cone  502  faces the atomizing assembly  102 , and the lower surface of the circular truncated cone  501  covers at least parts of the smoke outlet gaps. Specifically, in this embodiment, the lower surface of the circular truncated cone  501  covers two thirds of the smoke outlet gaps on the end surface  1012 . The above description is only for illustration, and is not a limit. 
         [0074]    At least two through-holes  504  are provided between the side  503  of the circular truncated cone  501  and each of the smoke outlet gaps on the end surface  1012 , the through-holes  504  on the side  503  of the circular truncated cone  501  and the smoke outlet gaps on the end surface  1012  are in one-to-one correspondence, and the through-holes  504  are configured to connect the smoke channel to the corresponding smoke outlet gaps. 
         [0075]    In this embodiment, the circular truncated cone  501  is arranged such that the upper surface of the circular truncated cone  501  is located in the center area of the end surface  1012 , the through-holes  504  of the circular truncated cone  504  are provided between the side face of the circular truncated cone  501  and each of the smoke outlet gaps  1011 , and there is no through-hole  504  between the upper surface of the circular truncated cone  501  and the smoke outlet gaps  1011  on the end surface of the suction nozzle cover. In this manner, the non-atomized e-liquid will hit the upper surface of the circular truncated cone  501  when flying to the center of the end surface  1012  under the force of the air flow, and cannot enter the smoke outlet gaps  1011 , thereby preventing the user from smoking the non-atomized e-liquid. And even if some e-liquid adheres on the side face of the circular truncated cone  501 , since the upper surface of the circular truncated cone  501  faces the atomizing assembly and the upper surface is smaller than the lower surface, the side face of the circular truncated cone  501  is advantageous for the e-liquid to drop back to the smoke channel under gravity, thereby avoiding that the e-liquid enters the through-holes  504  on the side face of the circular truncated cone  501  under the force of the air flow when adhering to the side face of the circular truncated cone  501 . 
         [0076]    In the actual implementation, the circular truncated cone  501  according to this embodiment may be replaced with a circular cone. Correspondingly, the center axis of the circular cone passes through the center of the end surface, the apex of the circular cone faces the atomizing assembly, and the lower surface of the circular cone covers at least parts of each of the smoke outlet gaps  1011 . The through-holes  504  are provided on the side of the circular cone, and correspond one-to-one to the smoke outlet gaps. 
         [0077]    In the present disclosure, the atomizing assembly  102  in the electronic cigarette body may be implemented with a variety of structure. A specific structure of the atomizing assembly of the electronic cigarette is described in detail in conjunction with  FIG. 1  hereinafter. Referring to  FIG. 1 , the atomizing assembly  102  further includes an atomizing sleeve  1024 . A tubular support frame  1025  is provided in the atomizing sleeve  1024 . Specifically, the support frame  1025  is a fiberglass pipe. In the actual implementation, the support frame  1025  may be made of other materials, which is not limited herein. 
         [0078]    An e-liquid storage space  1021  encircles the outside wall of the support frame  1025 , supported holes  1027  are provided on the side wall of the support frame  1025 , and the direction of the support holes  1027  is perpendicular to that of the support frame  1025 . An atomizing core  1022  passes through the support holes  1027 , and is fixed inside the support frame  1025 . Two ends of the atomizing core  1022  are inserted into the e-liquid storage space  1021 , so as to atomize the e-liquid in the e-liquid storage  1021 . A smoke channel  1023  extends along the empty center of the support frame  1025  from the atomizing core  1022  to the suction nozzle cover  101 . 
         [0079]    Preferably, a circular seal ring  1026  is provided at the end of the support frame  1025  facing the suction nozzle cover  101 , so as to seal the e-liquid storage space  1021  between the support frame  1025  and the atomizing sleeve  1024 . The smoke channel in the support frame  1025  is interconnected to the suction nozzle cover  101  via the through-hole in the center of the seal ring  1026 , such that the atomized e-liquid enters into the suction nozzle cover  101  through the through-hole in the center of the seal ring  1026 . In this embodiment, by providing the seal ring, the e-liquid in the e-liquid storage space  1021  can be prevented from flowing to the suction nozzle cover  101 . 
         [0080]    Since parts of atomized e-liquid flies to the suction nozzle cover  101  under the force of the air flow and adheres to the inner wall of the suction nozzle cover  101 . Under gravity, the e-liquid will slowly flow to the atomizing assembly and accumulate on the side of the seal ring  1026  facing the suction nozzle cover  101 . Therefore, preferably, an inner side of the seal ring  1026  is funnel-shaped, and the area of opening of the seal ring  1026  at the side facing the suction nozzle cover  101  is larger than that facing the atomizing assembly. In this manner, the e-liquid accumulated on the side of the seal ring  1026  facing the suction nozzle cover  101  will gradually flow to the center of the seal ring  1026  along the inner side of the seal ring  1026 , and flow back to the smoke channel  1023  in the atomizing assembly  102  through the through-hole in the center of the seal ring  1026 , avoiding being taken in by the user. 
         [0081]    In the present disclosure, the battery assembly  103  in the electronic cigarette body may be implemented with a variety of structure. A specific structure of the battery assembly of the electronic cigarette is described in detail in conjunction with  FIG. 1  hereinafter. Referring to  FIG. 1 , the battery assembly includes: 
         [0082]    a battery sleeve  1031 ; 
         [0083]    a battery  1032  provided in the battery sleeve  1031 ; 
         [0084]    a sensing assembly  1033  configured to generate a trigger signal; and 
         [0085]    a microcontroller electrically connected to the sensing assembly (not shown in the drawings). 
         [0086]    As shown in  FIG. 1 , in this embodiment, the sensing assembly preferably is implemented with an air flow sensing switch. The intensity of pressure in the electronic cigarette decreases when a user smokes through the suction nozzle cover  101 . The air flow sensing switch  1033  generates a trigger signal after detecting the decrease of the intensity of pressure. 
         [0087]    The microcontroller controls the battery  1032  of the battery assembly  103  to power the electronic cigarette after detecting the trigger signal, so as to enable the atomizing core  1022  of the electronic cigarette to atomize the e-liquid to form the smoke for the user. 
         [0088]    Certainly, the arrangement of the sensing assembly is not limited to that shown in  FIG. 1 . For example, an operation button can be provided on the surface of the electronic cigarette, the user presses the operation button if he wants to smoke, and the operation button generates the trigger signal based on the operation of the user. The microcontroller controls the battery  1032  of the battery assembly  103  to power the electronic cigarette after detecting the trigger signal, so as to enable the atomizing core  1022  of the electronic cigarette to atomize the e-liquid to form the smoke for the user. 
         [0089]    The present disclosure further discloses an atomizer, which is configured to form an electronic cigarette in conjunction with a battery assembly. A suction nozzle cover and an atomizing assembly are provided on the atomizer, and the suction nozzle cover is provided on an end surface of the atomizing assembly.
