Title: Cartridge and electronic cigarette

Description:
TECHNICAL FIELD 
     The present disclosure relates to the technical field of smoking sets, and in particular to a cartridge and an electronic cigarette containing the same. 
     BACKGROUND 
     Electronic cigarette is an electronic product simulating traditional cigarettes, which has the same look, smoke, taste and feeling as the traditional cigarette. The electronic cigarette changes an atomized liquid containing nicotine and the like into a vapor for a user to inhale, through atomizing and other means. Since the electronic cigarettes are easy to carry, generate no open flame and are environment friendly, they become a popular choice for many smokers. 
     An electronic cigarette generally includes a liquid storage part, a porous body, a heating body and a battery, wherein a liquid storage cavity is formed in the liquid storage part to store an atomized liquid, the porous body is configured for absorbing partial atomized liquid from the liquid storage cavity and temporarily storing it, the heating body contacts the porous body, and the heating body, when electrified, heats the atomized liquid transferred to the heating body from the porous body to form an aerosol for a user to directly inhale, then the aerosol enters the user&#39;s mouth through the gas outlet channel to bring a sense of stimulation and satisfaction to the user; the battery is mainly configured for supplying power to the heating body. 
     A Chinese patent with application number of 201721713285.9 provides an electronic cigarette and an atomizer thereof, wherein the porous body (referred to as a liquid conductor in the patent) has a liquid absorption surface facing towards the liquid storage cavity and an atomizing surface located outside the liquid storage cavity, the heating body (referred to as a heating element in the patent) is formed on the atomizing surface, the liquid absorption surface defines a groove configured for storing partial atomized liquid, such that the shortest conduction distance of the atomized liquid from the bottom wall of the groove to the atomizing surface is less than the shortest conduction distance from the liquid absorption surface to the atomizing surface, so that the porous body increases the speed of transferring the atomized liquid to the atomizing surface, thereby improving the speed of the electronic cigarette generating an aerosol. 
     The inventor finds a following problem in the process of implementing the above application. During the smoking process of the electronic cigarette, when passing the cold gas outlet channel, the aerosol of 200 degrees centigrade will partially liquified to form a condensed liquid on the inner wall of the gas outlet channel; if the user inhales the condensed liquid, the smoking experience of the user will be degraded; if the user shakes the condensed liquid out of the gas outlet channel, resource waste will be resulted. 
     SUMMARY 
     In order to solve the problems in the prior art that users are likely to inhale a condensed liquid, which affects user experience, or resource is wasted after the condensed liquid is shaken out, the present disclosure provides a cartridge and an electronic cigarette having the same, which can recycle the condensed liquid, such that the user does not inhale the condensed liquid. 
     First, the present disclosure provides a cartridge, which includes: 
     a liquid storage part, inside of which a liquid storage cavity is formed to store an atomized liquid; 
     a gas outlet channel, through which an aerosol generated inside the cartridge is discharged to the outside of the cartridge; 
     a porous body, which includes a main body having an atomizing surface, and two side parts arranged opposite to each other and extending from an opposite surface of the atomizing surface in a direction away from the atomizing surface, wherein a container is defined and formed between the two side parts and the main body to contain partial atomized liquid, the container is communicated with the liquid storage cavity, and the porous body also includes a connection part which is used to connect the two side parts; and 
     a heating body, which is arranged on the atomizing surface, wherein the heating body is configured for heating partial atomized liquid transferred from the container to the atomizing surface to form an aerosol for a user to inhale. 
     Compared with the prior art, the container to contain partial atomized liquid is formed between the two side parts and the main body of the porous body, which reduces the shortest conduction distance of the atomized liquid being transferred to the atomizing surface, and guarantees the liquid conduction rate of the porous body; furthermore, the connection part connecting the two side parts is communicated with the gas outlet channel, so that the condensed liquid formed by the atomized liquid on the inner wall of the gas outlet channel may be absorbed by the connection part and transferred to the atomizing surface to be atomized again, which not only reduces the risk of a user inhaling the condensed liquid, but also achieves the two-time utilization of the condensed liquid, thus preventing resource waste.

     Optionally, the two side parts are provided with bevels which are extending from the connection part towards two ends of the porous body. 
     The bevels on the two side parts that are extending from the connection part towards the two ends greatly reduce the phenomenon of stress concentration at the connection of the side part and improves the rigidity of the side part near the opening end. 
     Optionally, the length of the two side parts extending along the first direction is less than the length of the main body in the first direction. 
     Optionally, the liquid storage part is internally provided with a gas guide tube which forms the gas outlet channel; the cartridge further includes a support which is configured for accommodating the porous body and the heating body, the support includes a concave part connected to the gas guide tube, the connection part abuts against the concave part in a sealing manner, and a bottom wall of the concave part defines a first intercommunicating pore which is configured for guiding a condensed liquid formed inside the gas outlet channel onto the receiving surface.

     Compared with the prior art, the cartridge  100  and the electronic cigarette having the cartridge  100  provided in the present disclosure have at least the following beneficial effects. 
     The container  44  to contain partial atomized liquid is formed between the two side parts  42  and the main body  41  of the porous body  4 , which reduces the shortest conduction distance of the atomized liquid being conducted to the atomizing surface  411 ; under the condition of guaranteeing the liquid conduction rate of the porous body  4 , the connection part  43  is arranged to connect the two side parts  42 ; the connection part  43  on one hand enhances the rigidity of the two side parts  42 , and on the other hand the connection part  43  is communicated with the gas outlet channel  120 , so that the condensed liquid formed by the atomized liquid on the inner wall of the gas outlet channel  120  may be absorbed by the connection part  43  and transferred to the atomizing surface  411  to be atomized again, which not only reduces the risk of a user inhaling the condensed liquid, but also achieves the two-time utilization of the condensed liquid, thus preventing resource waste.

     The main body  41  of the porous body  4  is clamped between the sealing part  3122  and the first clamping part  313 , which not only facilitates the installation between the porous body  4  and the first sealing element  31 , but also prevents the porous body  4  separating from the first sealing element  31 , and guarantees the effective sealing of the first sealing element  31 . 
     The liquid isolator  6  is arranged between the second main body  51  and the porous body  4 , which avoids the fact that the atomized liquid leaked from the atomizing surface  411  directly leaks out of the cartridge  100  via the air inlet  513  on the second main body  51 , thus, on one hand the atomized liquid is prevented leaking out of the cartridge  100  to affect user experience during the transportation or storage process of the cartridge  100 , and on the other hand the leaked atomized liquid is prevented entering the battery rod assembly from the cartridge  100  to damage the electronic elements in the battery rod assembly.
