Title: Atomizer and atomizing assembly thereof

Description:
FIELD 
     The present invention relates to the technical field of electronic cigarette sets, and more specifically, to an atomizer and an atomizing assembly thereof. 
     BACKGROUND 
     Currently, the atomizers made of porous material in the market are usually ceramic atomizers, including a cylindrical ceramic atomizer and a square flat ceramic atomizer. Wherein, the cylindrical ceramic atomizer is in linear communication with the inlet and outlet air holes in a straight line, and the moisture contained in the smoke atomized by the cylindrical ceramic atomizer will be directly inhaled into the user&#39;s mouth, making the user experience poor. Besides, the cylindrical ceramic atomizer has a small application range and s single application scene. Moreover, due to that a wrapping cotton is needed, the wrapping cotton is slow in production speed and unstable in quality during the assembly process. While in the square flat atomizer, the heating wire can only be heated outside or at the bottom of the atomizer due to the limitation of the production process of the heating wire, and due to the limitation of the process, the resistance deviation of the heating wire is too large, and the quality of the finished product is unstable, which easily leads to an uneven heating, a core burning, an open circuit without resistance, and other phenomena.

     DETAILED DESCRIPTION 
     For better understanding of the technical features, objects and effects of the present invention, the specific embodiments of the present invention will be described in detail with reference to the accompanying drawings. 
     The present invention provides an atomizer of an electronic cigarette and an atomizing assembly thereof, configured to heat an e-liquid to generate smoke, so that the purpose of simulating a real smoke can be achieved through the user&#39;s suction. Specifically, the atomizing assembly provided in the present invention may include an atomizing body  10  made of a porous liquid conducting material, which may be specifically made of a porous ceramic material or other porous material, and can fully adsorb and store the e-liquid. Specifically, the atomizing body  10  is in a shape of a cube or a flat shape similar to a cube, and its interior includes an air passage  11  and a liquid inlet groove  12 . Wherein, when the user inhales, the air passage  11  is used as a flow passage for the airflow; the liquid inlet groove  12  is spaced disposed with the air passage  11 , and is used store the e-liquid and to supply the e-liquid to the atomizing body  10  in real time when the user is inhaling. The atomizing assembly in the present invention further includes a heating member  20  configured to heat the e-liquid to generate smoke. With the user&#39;s suction, the smoke generated by heating and atomizing the e-liquid flows along the air passage  11 , and then enters the user&#39;s mouth, so as to achieve the purpose of simulating the real smoke suction. 
     The air passage  11  of the atomizing assembly provided in the present invention is non-linear shaped, and may include, referring to  FIG.  4   , a first passage  111  and one or more second airways  112 . The first passage  111  and the second passage  112  are communicated with each other.

     With reference to  FIG.  9    to  FIG.  11   , when the atomizing assembly is the aforementioned lateral side liquid feeding atomizing assembly, the upper bracket  42  specifically includes a third sealing member  426  and a connecting member  427  arranged above the third sealing member  426 . The connecting member  427  is clamped between the third sealing member  426  and the suction passage  32  to provide a flow passage for the airflow. In this embodiment, the third sealing member  426  is used to isolate the liquid storage chamber  31  and the atomizing assembly along the circumference. The third sealing member  426  is internally provided with a receiving cavity  4261  for receiving the atomizing body  10 , and the atomizing body  10  is arranged in the receiving cavity  4261 . The top of the third sealing member  426  is provided with a fourth liquid through hole  4262  communicated to the receiving cavity  4261 , and the e-liquid in the liquid storage chamber  31  enters the receiving cavity  4261  through the fourth liquid through hole  4262 , so as to enter the liquid inlet groove  12  arranged on the lateral side of the atomizing body  10 . In order to ensure that the e-liquid can enter the liquid inlet groove  12  from the lateral side of the atomizing body  10 , in this embodiment, the atomizing body  10  and the receiving cavity  4261  are disposed with a gap circumferentially therebetween, that is, a gap is formed between a side wall of the atomizing body  10  and an inner wall of the receiving cavity  4261 , and the gap is used to store the e-liquid, so that the e-liquid can enter the liquid inlet groove  12  from the lateral side of the atomizing body  10 .  FIG.  10    and  FIG.  11    respectively show the sectional views under two different sections of the atomizer in this embodiment, wherein the sections in  FIG.  10    and FIG.  11  are perpendicular to each other. Furthermore, since the top surface of the atomizing body  10  is abutted against the top surface of the receiving cavity  4261 , the top surface of the atomizing body  10  has the risk of blocking the first liquid through hole  4241 , in this embodiment, the fourth liquid through hole  4262  is at least partially communicated with the receiving cavity  4261 , which may refer to  FIG.  10    for details, wherein the arrows in  FIG.  10    show the flow path of the e-liquid in this embodiment. As a specific embodiment, the atomizing body  10  is coaxial with the third sealing member  426 , and the maximum distance from the periphery of the top surface of the atomizing body  10  to the center of the top surface of the atomizing body  10  is less than the maximum distance from the periphery of the fourth liquid through hole  4262  to the center of the top surface of the third sealing member  426 , so that the top surface of the atomizing body  10  will not completely block the fourth liquid through hole  4262 , the fourth liquid through hole  4262  is at least partially communicated with the receiving cavity  4261  after the atomizing assembly is assembled, so that the fourth liquid through hole  4262  can be used as a liquid passage to communicate the liquid storage chamber  31  with liquid inlet groove  12 , ensuring that the e-liquid can smoothly enter the receiving cavity  4261 . 
     Further, in this embodiment, the second passage  112  of the atomizing assembly is provided with an air outlet  113  on the top surface of the atomizing assembly, and the third sealing member  426  is further provided with a fifth air through hole  4263  disposed corresponding to the air outlet  113 . In this embodiment, the connecting member  427  is coaxial with the atomizing body  10  and the third sealing member  426 , and is provided with a sixth air through hole  4271  communicating the fifth air through hole  4263  with the suction passage  32  in a penetrating manner. The sixth air through hole  4271  is preferably sleeved at the bottom of the suction passage  32 , so that the fifth air through hole  4263  and the sixth air through hole  4271  are communicated to form the air guiding passage. Referring to  FIG.  11   , the dotted line arrows in  FIG.  11    show the flow path of the airflow in the atomizer, the smoke generated by atomizing the e-liquid leaves the atomizing body  10  from the air outlet  113 , enters the suction passage  32  through the air guiding passage, and then enters the user&#39;s mouth. 
     In the above two embodiments, the first sealing member  424 , the second sealing member  425  and the third sealing member  426  are all made of elastic materials, preferably silicone, rubber or other elastic sealing materials. 
     Further, in the above two embodiments, the bottom bracket  41  is provided with an air inlet  411  that runs through axially, when the user inhales, the external airflow enters the atomizer through the air inlet  411 , and then enters the air passage  11  to start atomization. In some embodiments, the air inlet  411  is coaxial with the first passage  111 . In other embodiments, a plurality of the air inlets  411  may be provided and uniformly distributed on the bottom bracket  41  to increase the air flow. Furthermore, the air inlet  411  is further provided therein with a filter grid  4111  for filtering impurities in the external air. Specifically, the filter grid  4111  is honeycomb shaped, that is, is provided with a plurality of through holes, which can block the impurities in the air outside the atomizer during inhalation, so as to prevent the airflow from bringing the impurities into the air passage  11  during inhalation to cause blockage or even damage to the atomizing assembly. The above only describes one specific embodiment of the filter grid  4111 , it may be understood that other filter device that can be used to block the impurities in the air may be used as the filter grid  4111  in the present invention.
