     TECHNICAL FIELD 
     The present disclosure relates to an atomization generating device, and more specifically, to a portable atomization generating device. 
     BACKGROUND 
     A currently available electronic cigarette, also known as an atomization generating device, is typically portable. The electronic cigarette includes a cartridge and a main body. An upper portion of the cartridge is provided with an electronic cigarette liquid (“E-liquid”) storage tank, and a lower portion is provided with an atomizing core disposed on a bottom base. The bottom base includes an air inlet connected with the atomizing core. The upper portion of the cartridge is provided with an air outlet. The air inlet and the air outlet are connected through a vapor channel. A side wall of the vapor channel is provided with an E-liquid inlet. The E-liquid inlet is connected with the E-liquid storage tank. The atomizing core disposed on the bottom base is provided in the vapor channel. The atomizing core includes an E-liquid guiding body and a heating wire. The E-liquid guiding body absorbs the E-liquid from the E-liquid storage tank through the E-liquid inlet. The E-liquid stored in the E-liquid storage tank continuously flows to the E-liquid guiding body through the E-liquid inlet. After the heating wire heats the E-liquid already absorbed by the E-liquid guiding body to atomize the E-liquid, the E-liquid guiding body continues to absorb additional E-liquid from the E-liquid storage tank. The upper portion of the main body of the electronic cigarette (or atomization generating device) is provided with a receiving chamber. The lower portion of the main body is provided with an electrical circuit board and a battery. The electrical circuit board is connected with the battery. The atomizing core disposed in the cartridge is connected with the electrical circuit board. When a user operates the electronic cigarette, the atomizing core is electrically connected and powered such that the E-liquid guided in by the E-liquid guiding body is atomized. A gas generated from atomizing the E-liquid moves upwardly to flow out from the air outlet provided at the upper portion of the vapor channel. When this type of electronic cigarette is used, the cartridge is typically mounted inside the receiving chamber at the upper portion of the main body. An external air may enter a bottom portion of the cartridge through a gap located between an exterior wall of the cartridge and the receiving chamber. The external air flows upwardly along the air inlet disposed at the bottom portion of the cartridge. The external air further enters the atomizing core and mixes with the gas generated from atomizing the E-liquid. The mixture moves upwardly and flows out through the air outlet provided at the upper portion of the vapor channel, thereby accomplishing an exchange cycle between the atomizing core disposed inside the electronic cigarette and external air. 
     For a smooth air intake of the electronic cigarette and for reliable mounting of the cartridge, the size of the cartridge and the size of the receiving chamber need to be suitably matched. That is, the size of the gap between the exterior wall of the cartridge and the receiving chamber needs to be suitable. An overly large gap may cause the cartridge to be easy to become loose, which tends to result in an E-liquid leakage and other contamination. An overly small gap may render it difficult for the external air to enter the electronic cigarette, resulting in an insufficient amount of air intake for the electronic cigarette, which may affect the texture or taste of the atomized E-liquid. In a practical design, for reliable mounting of the cartridge to avoid contamination, the gap between the exterior wall and the receiving chamber may be maintained within a relatively small range. Nonetheless, during the manufacturing process, errors may occur in the size of the cartridge and the size of the receiving chamber. Such errors may result in an overly tight mounting of the cartridge inside the receiving chamber, which can result in an insufficient amount of air intake for the electronic cigarette. 
     When the electronic cigarette is used by a user, the cartridge is mounted to the receiving chamber disposed at the upper portion of the main body. The corresponding positive and negative conductive terminals respectively disposed at the bottom portion of the cartridge and at the receiving chamber are plug-connected with one another to provide an electric power to the atomizing core. The plug-connection configuration tends to cause the cartridge to be incorrectly plugged in a wrong direction, resulting in a switching of the electrodes of the conductive terminals disposed at the bottom portion of the cartridge. That is, the electric current in a heating member (e.g., a heating wire) no longer flows in the positive direction to provide the electric power normally. Instead, the electric current flows in a reversed direction to provide a reverse power supply. This type of electronic cigarette cannot avoid a reverse power supply. Long term use of this type of electronic cigarette tends to cause damages to the cartridge, rendering cartridge unusable. 
     In this type of portable electronic cigarette main body, the conductive terminals and the heating member of the atomizing core are typically welded together. When this type of cartridge is used, the connection between the heating member and the conductive terminals is not secure, and tends to break apart. This is because after the heating member is welded with the conductive terminals, the welded heating member and the conductive terminals are assembled with other elements in the manufacturing process, and in the assembling process, the heating member and the conductive terminals tend to separate apart due to poor quality welding, vibration, etc., which may render the product unusable. 
     In the meantime, this type of portable electronic cigarette main body is typically provided with a pressing-button switch at an exterior surface. The pressing-button switch may be pressed to trigger the operation of the atomizing core. This method of triggering the atomizing core through the pressing-button switch entails continuously pressing the pressing-button by a human hand, which is inconvenient for the user in practical operations. In addition, long-term pressing of the pressing-button switch tends to cause damages to the pressing-button switch, rendering the electronic cigarette unusable. In the meantime, it is common that the internal structure of this type of portable electronic cigarette is not reasonable, not compact, and the space utilization rate is not high. 
     SUMMARY 
     The objective of the present disclosure is to overcome the defects or disadvantages of the existing technologies. First, the present disclosure provides a new, portable atomization generating device. The portable atomization generating device includes an independent air intake structure. The atomization generating device includes various advantageous features. For example, the atomization generating device includes a novel design for air flow channels. The structure of the atomization generating device makes it easy for the external air to enter. In addition, with the atomization generating device, the texture of the gas generated from atomizing the E-liquid can be maintained or enhanced. 
     The independent air intake structure provided by various embodiments of the present disclosure may be configured to connect the atomizing core with the external air. That is, the independent air intake structure may provide an independent air channel for the external air to enter the atomization generating device, which is different from the conventional air intake channel provided through the gap between the exterior wall of the cartridge and the receiving chamber as included in a conventional atomization generating device. The independent air intake structure provides an air intake channel for the external air to enter the atomizing core, which is independent of a conventional design, thereby enabling a sufficient air intake to be provided for the atomization generating device, which enhances the texture of the gas generated from atomizing the E-liquid. 
     Compared with the conventional design, in the disclosed new design, the manner in which the external air enters the atomizing core is drastically changed. The air intake is no longer limited by the size of the gap between the cartridge and the receiving chamber and the manufacturing precision. Accordingly, the issue of insufficient air intake caused by the size of the gap between the cartridge and the receiving chamber being too small is resolved. 
     The portable atomization generating device including the independent air intake structure may include: 
     a cartridge including an exterior housing. An opening may be provided at a lower portion of the exterior housing. A top portion of the exterior housing may be provided with an air outlet, i.e., a cigarette mouthpiece. A side wall of the exterior wall may be provided with an open hole. The cartridge may also include a bottom base mounted at the opening provided at the lower portion of the exterior housing. An atomizing core may be provided at an upper portion of the bottom base. The atomizing core and the cigarette mouthpiece may be connected through a vapor channel; 
     a main body including a receiving chamber provided at an upper portion for receiving the cartridge. A side wall of the receiving chamber may be provided with an air inlet. The air inlet of the main body may correspond to the open hole on the exterior housing of the cartridge, such that the external air can be guided into the cartridge; 
     In the disclosed structure, an air guiding channel may be provided at the bottom base of the cartridge. An end of the air guiding channel may be connected with the atomizing core. Another end of the air guiding channel may be connected with the open hole on the exterior housing of the cartridge and the corresponding air inlet on the main body. The air guiding channel may be configured to guide the external air into the atomizing core. 
     In some embodiments, the air guiding channel may be a bottom base through hole extending throughout the inside of the bottom base and connected with the atomizing core. The bottom base through hole may be directly connected with the open hole of the exterior housing of the cartridge and the corresponding air inlet on the main body that aligns with the open hole, which can guide the external air into the atomizing core. 
     In some embodiments, the bottom base through hole may include at least one first channel disposed inwardly. Each first channel may bend and extend upwardly to provide a second channel. The second channel may be located below the atomizing core and may be connected with the atomizing core. 
     In some embodiments, the bottom base may have more than one bottom base through hole, for example two. In such embodiments, the two first channels of the two bottom base through holes may be distributed opposingly. Each first channel may be connected with a second channel, through which the first channel may be connected with the atomizing core. 
     In some embodiments, the air guiding channel disposed at the bottom base may be an air guiding groove concavely and inwardly disposed at an exterior surface at a lower portion of the bottom base. An end of the air guiding groove may be connected with an external environment through the open hole on the exterior housing of the cartridge and the corresponding air inlet of the main body that is aligned with the open hole. Another end of the air guiding groove may be connected with the atomizing core through the bottom base through hole. In some embodiments, the first channel of the bottom base through hole may be provided at an inner wall of the air guiding groove. 
     When the air guiding groove is concavely and inwardly disposed in a ring shape at the exterior surface of the bottom base, i.e., when the air guiding groove includes a ring shape, and is circularly disposed at the exterior surface at a lower portion of the bottom base, the atomization generating device of the present disclosure may also be referred to as a side air intake circular flow type atomization generating device. The side air intake circular flow type atomization generating device includes various advantageous features. For example, the atomization generating device include a novel air channel design. The structure of the atomization generating device makes it easy for the external air to enter. In addition, with the atomization generating device, the texture of the gas generated from atomizing the E-liquid can be maintained or enhanced. In some embodiments, the two opposingly distributed first channels may be located at two opposing sides of the ring-shaped air guiding groove. 
     An embodiment of the present disclosure also provides a portable atomization generating device, which includes a snap-fitting structure. The snap-fitting structure may be formed by a snap-fitting opening provided at a side wall of the exterior housing of the cartridge and a protrusion provided at the bottom base of the cartridge. The open hole at the side wall of the exterior housing of the cartridge may be configured as the snap-fitting opening. The protrusion may be disposed at the bottom base of the cartridge at a location corresponding to the snap-fitting opening. The protrusion may be configured to couple or engage with the snap-fitting opening to securely mount the bottom base to the exterior housing of the cartridge through the snap-fitting manner. 
     In some embodiments, a gap is pre-configured between the protrusion and the snap-fitting opening to allow the external air to enter the air guiding channel conveniently. 
     In some embodiments, a connection groove may be concavely and inwardly disposed at an exterior surface of the protrusion. The connection groove may be connected with the external environment through the snap-fitting opening disposed at the side wall of the exterior housing of the cartridge. The connection groove may be in a gaseous connection with the atomizing core through the air guiding groove. 
     In some embodiments, the protrusion may include an upper surface facing in a direction toward the cigarette mouthpiece, a lower surface facing in a direction toward the bottom base, and an exterior surface facing in a direction toward an external environment of the electronic cigarette. An inner surface of the protrusion may be fused with the exterior surface of the bottom base. 
     In some embodiments, the connection groove may be disposed inwardly and downwardly from the exterior surface of the protrusion. In addition, the connection groove extends outwardly to penetrate throughout a lower surface of the protrusion. The air guiding groove may be horizontally disposed below the protrusion and is connected with the connection groove. 
     In some embodiments, the connection groove may be disposed inwardly and upwardly from the exterior surface of the protrusion. The connection groove extends outwardly to penetrate throughout the upper surface of the protrusion. The air guiding groove may be horizontally disposed above the protrusion and may be connected with the connection groove. 
     In some embodiments, the connection groove may be disposed at a middle or center portion of the protrusion to penetrate throughout the upper and lower surfaces of the protrusion, and may be interposingly connected with the air guiding groove that is concavely disposed at an exterior surface of the bottom base in a direction toward an inner surface of the protrusion. 
     To further improve the sealing of the cartridge, a rubber ring may be sleeve-fit onto an upper portion of the bottom base. The bottom base and the exterior housing may be sealed by the rubber ring. The rubber ring may be located above the protrusion. 
     Compared to the conventional design, the atomization generating device having the independent air intake structure provided by the present disclosure drastically changes the manner in which the external air enters the atomizing core. The issue related to the size of the gap between the cartridge and the receiving chamber in the conventional design is resolved. Accordingly, the issue related to an insufficient amount of air intake caused by the sizes of the cartridge and the receiving chamber is resolved. The disclosed atomization generating device may include an air inlet provided at an exterior wall of the receiving chamber. The external air enters the snap-fitting opening of the cartridge through the air inlet, and sequentially flows through the connection groove, the air guiding groove, the first channel, and the second channel. The gas generated by atomizing, by the atomizing core, the E-liquid may be guided to the cigarette mouthpiece through the vapor channel. Accordingly, the atomized E-liquid (which is turned into the gas) may be guided out timely. As a result, the deficiency of having an insufficient air intake amount due to the size of the gap being too small can be avoided. In addition, the texture of the atomized E-liquid can be enhanced. The disclosed atomization generating device can more thoroughly atomize the E-liquid, thereby increasing the fineness of the texture. 
     Embodiments of the present disclosure also provide a portable atomization generating device, which includes a reverse power supply avoidance function. The atomization generating device having the reverse power supply avoidance function can avoid the occurrence of reverse plugging that may provide a reverse power supply to the atomizing core.

When the cartridge is rotated for an angle around the center line, the first snap-connecting member and the second snap-connecting member may not be engaged with one another, and the cartridge may not be correctly loaded into the receiving chamber. In some embodiments, the angle for which the cartridge is rotated around the center line may be θ, where 0°&lt;θ&lt;180° or θ=180°. 
     In some embodiments, a second groove may be provided at a lower surface of the bottom base. The first snap-connecting member may be the second groove. The first end surface may be provided with a first air guiding channel. The first air guiding channel may protrude from an upper surface of the first end wall. The second snap-connecting member may be the first air guiding channel protruding from the first end wall. The first air guiding channel may be inserted at a location of the second groove where the cartridge may be correctly loaded into the receiving chamber. 
     In some embodiments, the atomizing core and the cigarette mouthpiece may be connected through the vapor channel. The bottom base may be provided with an air guiding groove. A first channel may be inwardly provided at an inner wall of the air guiding groove. The first channel may bend upwardly and extend to form or provide a second channel. The first channel may also bend downwardly and extend to form or provide a third channel. A first snap-fitting hole may be provided at a side wall of the exterior housing. The air guiding groove may correspond to the first snap-fitting hole. A protrusion may be provided at a portion of the bottom base corresponding to the first snap-fitting hole.

The two short sides may be opposingly configured. The long sides and the short sides may be connected. A length of a long side may be greater than a length of a short side. 
     The atomization generating device having the foolproof structure provided by the embodiments of the present disclosure may include a reverse plugging avoidance feature. That is, when the cartridge is loaded into the receiving chamber along the center line, the first snap-connecting member and the second snap-connecting member are engaged with one another, such that the cartridge can be correctly loaded into the receiving chamber. Under this circumstance, the lead terminals and the connection terminals are connected to establish an electrical connection therebetween. The first magnet and the second magnet attract one another to bring the cartridge and the main body into tight or close contact, thereby realizing the normal operation of the electronic cigarette. When the cartridge is rotated around the center line for an angle, the first snap-connecting member and the second snap-connecting member are not engaged with one another, and the cartridge cannot be correctly loaded into the receiving space. The lead terminals and the connection terminals are not electrically connected. As a result, the electronic cigarette cannot operate normally.

     The present disclosure also provides a press-connection method for terminals of the atomization generating device, and an atomization generating device manufactured with terminals connected using the disclosed press-connection method. The atomization generating device includes features such as secure connections and a long lifetime. 
     In some embodiments, the bottom base of the cartridge of the atomization generating device may include a support member, a center rod, a loading hole, a connecting wall, an insertion hole, and a passing hole. A diameter of the insertion hole may be greater than a diameter of the passing hole. The atomizing core of the cartridge may include an E-liquid guiding body and a heating member. Two ends of the heating member may each include an extending member. When the atomizing core is pushed downwardly, the extending member may enter the passing hole and arrive at the insertion hole, and ultimately protrude from a lower surface of the bottom base. A lower portion of the E-liquid guiding body may be press-connected with the loading hole. The cartridge may also include a rubber sleeve. The rubber sleeve may include a sleeve hole configured to receive the extending member inserted therethrough. The cartridge may also include lead terminals configured to insert into the sleeve hole of the rubber sleeve, such that an exterior wall of the lead terminals presses the extending member. By adopting the tight pressing method, the reliability of the connection is significantly enhanced. The scenarios of falling off or separating of parts of the electronic cigarette under an external force can be avoided. The scenarios of the heating member and the connection terminals being separated from one another caused by the assembling process and external forces can be effectively avoided. 
     In some embodiments, an end of the extending member may be fixed such that the connection terminals can be inserted upwardly into the sleeve hole, thereby tightly mounting the extending member between the connection terminals and the sleeve hole. 
     In some embodiments, the rubber sleeve may be inserted upwardly into the insertion hole, such that the rubber sleeve abuts against a top wall of the insertion hole. 
     In some embodiments, the extending member may be moved downwardly to protrude from a lower surface of the bottom base. After a lower portion of the E-liquid guiding body is press-connected with the loading hole, when the extending member is pulled downwardly with a force, the E-liquid guiding body may tightly press the loading hole. 
     The press-connection method for press-connecting the terminals of the atomization generating device may include the following steps: 
     a. providing a bottom base. A support member and a center rod may extend upwardly from the bottom base. A loading hole may be downwardly provided at an upper surface of the support member. The center rod may be located inside the support member. An inner wall of the support member and an exterior wall of the center rod may be at least partially hollowed out.

     DETAILED DESCRIPTION OF THE EMBODIMENTS 
     The technical solution of the embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. The described embodiments are merely some embodiments of the present disclosure, and are not all embodiments of the present disclosure. Based on the embodiments of the present disclosure, a person having ordinary skills in the art can obtain other embodiments without creative labor. Such embodiments all fall within the scope of protection of the present disclosure. 
     As shown in  FIG. 1 - FIG. 19 , embodiments of the present disclosure provide an atomization generating device having an independent air intake structure. The atomization generating device may include a cartridge  1  including an exterior housing  11 . A cigarette mouthpiece  111  may be disposed at a top portion of the exterior housing  11 . An open hole  112  may be provided at a side wall of the exterior housing  11 . The cartridge  1  may also include a bottom base  12  disposed at an opening provided at a lower portion of the exterior housing  11 . An atomizing core  13  may be disposed at an upper portion of the bottom base  12 . The atomizing core  13  and the cigarette mouthpiece  111  may be connected through a vapor channel  14 . An E-liquid storage tank  15  may be provided at an upper space of the cartridge  1 . The E-liquid storage tank  15  and the atomizing core  13  may be connected. 
     The atomization generating device having the independent air intake structure may also include a main body  2 . A receiving chamber  21  may be formed at an upper portion of the main body  2  for receiving the cartridge  1 . An air inlet  211  may be provided at a side wall of the receiving chamber  21 . The air inlet  211  of the main body  2  may correspond to and be aligned with the open hole  112  provided at the side wall of the cartridge  1  to allow the external air to be guided into the cartridge  1 . 
     In some embodiments, an air guiding channel may be provided at the bottom base  12  of the cartridge  1 . An end of the air guiding channel may be connected with the atomizing core  13 . Another end of the air guiding channel may be connected with the open hole  112  of the exterior housing  11  of the cartridge  1  and the corresponding air inlet  211  of the main body  2 . The air guiding channel may be configured to guide the external air into the atomizing core  13 . 
     The air guiding channel may be configured as a bottom base through hole  121  that may extend throughout the inside of the bottom base  12  to connect with the atomizing core  13 . The bottom base through hole  121  may be directly connected with the open hole  112  of the exterior housing  11  of the cartridge  1  and the corresponding air inlet  211  of the main body  2  that is aligned with the open hole  112 , and may guide the external air into the atomizing core  13 . 
     The bottom base through hole  121  may include at least one first channel  1211  disposed inwardly, and a second channel  1212  that bends and extends upwardly. The second channel  1212  may be located below the atomizing core  13  and may be connected with the atomizing core  13 . 
     When more than one open hole  112  is provided at the side wall of the cartridge  1  and more than one corresponding air inlet  211  that is aligned with the open hole  112  is provided at the main body  2 , the bottom base  12  may include the same number of bottom base through holes  121 . Each bottom base through hole  121  may include the first channel  1211  and the second channel  1212 . Each first channel  1211  may be connected with the atomizing core  13  through the corresponding second channel  1212 . In some embodiments, the bottom base  12  may include two bottom base through holes  121  opposingly disposed at the bottom base  12 . 
     For the convenience of use and to avoid contamination, the air guiding channel  121  on the bottom base  12  may include an air guiding groove  1213  concavely and inwardly disposed at an exterior surface of a lower portion of the bottom base  12 . The bottom base through hole  121  may be disposed at an inner wall of the air guiding groove  1213 , and may include the first channel  1211  and the second channel  1212 . An end of the air guiding groove  1213  may be connected with the external environment through the open hole  112  provided at the side wall of the cartridge  1  and the corresponding air inlet  211  of the main body  2  that is aligned with the open hole  112 , another end may be connected with the atomizing core  13  through the bottom base through hole  121 . In this configuration, the bottom base through hole  121  may not be directly connected with the open hole  112  on the side wall of the cartridge  1  and the corresponding air inlet  211  on the main body  2 . Rather, the bottom base through hole  121  may be connected with the open hole  112  on the side wall of the cartridge  1  and the corresponding air inlet  211  of the main body  2  through the air guiding groove  1213 , thereby avoiding potential contamination that may be caused by the direct connection, and providing convenience for use. Accordingly, the external air may enter the open hole  112  on the exterior housing  11  of the cartridge  1  through the air inlet  211  on the main body  2 , and enter the air guiding groove  1213  through the open hole  112  on the exterior housing  11  of the cartridge  1 . The external air may then enter the first channel  1211  through the air guiding groove  1213 , and enter the second channel  1212  and the atomizing core  13 . The gas generated by atomizing the E-liquid by the atomizing core  13  may be guided to the cigarette mouthpiece  111  through the vapor channel  14 . 
     For the convenience of assembling the bottom base  12  of the cartridge  1  and the exterior housing  11 , embodiments of the present disclosure provide an atomization generating device including a snap-fitting structure. The atomization generating device includes features such as a novel design, being convenient for the E-liquid to enter, and being convenient for assembling. The snap-fitting structure may be formed by the open hole  112  on the exterior housing  11  of the cartridge  1  and a protrusion on the bottom base  12  of the cartridge  1 . That is, a protrusion  122  may be disposed at a portion of the bottom base  12  corresponding to the open hole  112  on the exterior housing  11 . The protrusion  122  may snap-fit in the open hole  112  of the exterior housing  11 , thereby mounting the bottom base  12  on the exterior housing  11  of the cartridge  1  in a snap-fitting manner. Therefore, the open hole  112  on the exterior housing  11  may also be referred to as a snap-fitting hole  112 . The protrusion  122  may be configured to engage with the snap-fitting hole  112  to mount the bottom base  12  to the exterior housing  11  of the cartridge  1  in the snap-fitting manner to assemble as the cartridge  1 . A gap may be pre-configured between the protrusion  122  and the snap-fitting hole  112 , such that the external air can conveniently enter the air guiding groove  1213  through the gap. 
     The snap-fitting mounting assembly may be used in combination with the bottom base through hole  121  described in the above embodiments. The bottom base through hole  121  may be horizontally disposed, opening inwardly from an exterior surface of a lower portion of the bottom base  12 . That is, the bottom base through hole  121  may open inwardly toward an inside of the bottom base from the protrusion  122 . In this type of configuration, the bottom base through hole  121  may be disposed inside the bottom base  12 , for example, at least partially or fully inside the bottom base  12 . An air inlet of the bottom base through hole  121  may be at an exterior side of the bottom base  12 , and the rest of the bottom base through hole  121  may be inside the bottom base  12 , without being exposed. This type of channel design has a short air flow path. The specific air flow path may be: the external air enters the bottom base through hole  121  through the gap pre-configured between the protrusion  122  and the snap-fitting hole  112 , and flows inwardly through the bottom base through hole  121 . The external air then enters the atomizing core  13  through the first channel  1211  and the second channel  1212 , and continues to enter the cigarette mouthpiece  111  through the vapor channel  14 . 
     To improve air intake efficiency and assembling quality, a connection mechanism may be provided on the protrusion  122 . For example, a connection groove  1221  may be disposed at an exterior surface of the protrusion  122 . The connection groove  1221  may be connected with the external environment through the snap-fitting hole  112  on the side wall of the exterior housing  11  of the cartridge  1 , and may be connected with the atomizing core  13  through the air guiding groove  1213 . The protrusion  122  may include an upper surface facing the cigarette mouthpiece  111 , a lower surface facing the bottom base  12 , and an exterior surface facing an exterior of the electronic cigarette. An inner surface facing an inside of the electronic cigarette may be integral with an exterior surface of the bottom base  12  of the cartridge  1  as a single piece. The connection groove  1221  may be disposed inwardly and downwardly from the exterior surface of the protrusion  122 , and may extend outwardly to penetrate throughout the lower surface of the protrusion  122 . The air guiding groove  1213  may be disposed below the protrusion  122  and may be connected with the connection groove  1221 . The connection groove  1221  may be disposed inwardly and upwardly from the exterior surface of the protrusion  122  and may penetrate throughout the upper surface of the protrusion  122 . The connection groove  1221  may be connected with the air guiding groove  1213  disposed above the protrusion  122 . The connection groove  1221  may be disposed at a center portion of the protrusion  122  to penetrate throughout the upper and lower surfaces of the protrusion  122 , and may be interposingly connected with the air guiding groove  1213  concavely disposed at the exterior surface of the bottom base  12  in a direction toward an inner surface of the protrusion  122 . 
     As shown in  FIG. 1 - FIG. 19 , there may be two snap-fitting mounting assemblies disposed at two opposing sides in a radial direction of the atomization generating device. This configuration may be implemented in, but not limited to, atomization generating devices having an oval shaped or a substantially oval shaped cross section. In some embodiments, the atomization generating device of the present disclosure may also include more than two snap-fitting structures, although more than two snap-fitting structures may increase the complexity of the product and manufacturing cost, and hence are not commonly adopted in manufacturing. 
     When the air guiding groove  1213  of the atomization generating device is circularly disposed concavely and inwardly from the exterior surface of the bottom base  12 , i.e., when the air guiding groove  1213  has a ring shape, and is circularly disposed at the exterior surface of a lower portion of the bottom base  12 , the atomization generating device provided by the embodiments of the present disclosure may also be referred to as a side air intake circular flow type atomization generating device. The ring-shaped air guiding groove  1213  may be horizontally disposed, and may be inwardly disposed from the protrusion  122  along the lower surface of the bottom base  12 . In this channel design, the air guiding groove  1213  is inwardly disposed at the bottom base  12 . The air guiding path is smoother and may not be prone to be clogged. The specific air flow path may be: the external air enters the air guiding groove  1213  through the gap pre-configured between the protrusion  122  and the snap-fitting hole  112  or through the connection groove  1221  disposed on the protrusion  122 , and flows inwardly along the air guiding groove  1213 . Then the external air enters the atomizing core  13  through the first channel  1211  and the second channel  1212 . The external air continues to enter the cigarette mouthpiece  111  through the vapor channel  14 . 
     To improve the sealing of the cartridge  1 , a rubber ring  123  may be disposed to sleeve fit onto an upper portion of the bottom base  12 . The bottom base  12  and the exterior housing  11  may be sealed through the rubber ring  123 . Thus, the E-liquid stored in the E-liquid storage tank  15  may not leak from the space between the bottom base  12  and the exterior housing  11 . The E-liquid storage tank  15  may be formed by an inner wall of the exterior housing  11 , an upper portion of the bottom base  12 , the vapor channel  14 , and the cigarette mouthpiece  111 .

     Compared with a conventional design, the atomization generating device provided by the present disclosure provides a drastically different structure for external air to enter the atomizing core  13 . The issue related to an insufficient air intake amount caused by the size of the gap between the cartridge  1  and the receiving chamber  21  in a conventional design is resolved. That is, the issue related to an insufficient air intake amount caused by the sizes of the cartridge  1  and the receiving chamber  21  in a conventional design is resolved. The disclosed atomization generating device may include the air inlet  211  provided at an exterior wall of the receiving chamber  21 . The external air may sequentially enter the atomizing core  13  through the snap-fitting hole  112 , the air guiding groove  1213 , the first channel  1211 , and the second channel  1212 . The gas generated by atomizing the E-liquid can be directed out of the electronic cigarette timely, thereby avoiding the deficiency of having an insufficient amount of air intake due to an overly small gap. As a result, the texture of the E-liquid can be enhanced. The atomization of the E-liquid is more thorough, and the texture is finer. 
     As shown in  FIG. 1 - FIG. 19 , the present disclosure also provides an atomization generating device having a reverse power supply avoidance function. That is, the atomization generating device includes a feature of avoiding reverse plugging that may provide a reverse power supply to the atomizing core  13 .

     During charging, the charging base  3  may be sleeve-fit at a bottom portion of the main body  2 . The user may not need to consider the positive and reverse directions of the charging base  3 . Because the first charging terminal  311  and the third charging terminal  313  are respectively located at two sides of the second charging terminal  312 , and are symmetrically distributed with respect to the second charging terminal  312 , and because two fourth magnets  33  are respectively located at two sides of the first charging terminal  311  and the third charging terminal  313 , and are symmetrically distributed, at the bottom portion of the main body  2 , the first socket  261  and the third socket  263  are respectively located at two sides of the second socket  262 , and are symmetrically distributed with respect to the second socket  262 .

As a result, the atomization generating device includes features such as secure connections and a long lifetime. The structure of the cartridge and body of the atomization generating device may be the same as or similar to those described above in the previous embodiments, which are not repeatedly described here. 
     As shown in  FIG. 1 - FIG. 9 , embodiments of the present disclosure provide a press-connection method for connecting terminals of an atomization generating device. The method may include the following steps: 
     a. providing a bottom base  12 . A support member  124  and a center rod  126  may extend from the bottom base  12 . A loading hole  1242  may be downwardly provided at an upper surface of the support member  124 . The center rod  126  may be located inside the support member  124 . An inner wall of the support member  124  and an exterior wall of the center rod  126  may be at least partially hollowed out. A bottom portion of the center rod  126  and a bottom portion of the support member  124  may be connected through a connecting wall  1243 . The method may also include providing an insertion hole  1244  disposed upwardly from a lower surface of the bottom base  12 . The insertion hole  1244  may extend throughout the connecting wall  1243 , and form a passing hole  1254  at the connecting wall  1243 . A diameter of the insertion hole  1244  may be greater than a diameter of the passing hole  1254 . 
     b. providing an atomizing core  13 . The atomizing core  13  may include an E-liquid guiding body  131  and a heating wire  132 . The heating wire  132  may be wounded around the E-liquid guiding body  131 . Two ends of the heating wire  132  may respectively include an extending member  1321 . The extending member  1321  may be disposed at an inner side of the support member  124 . The E-liquid guiding body  131  may be aligned with the loading hole  1241 . When the atomizing core  13  is pushed downwardly, the extending member  1231  may enter the hollowed out areas of the inner wall of the support member  124  and the exterior wall of the center rod  126 . When the atomizing core  13  is further pushed downwardly, the extending member  1321  may enter the passing hole  1245 , and enter the insertion hole  1244  along the passing hole  1245 . Finally, the extending member  1321  may protrude from a lower surface of the bottom base  12 . A lower portion of the E-liquid guiding body  131  may be press-connected with the loading hole  1242 . 
     c. providing a rubber sleeve  16  having a sleeve hole  161 . The extending member  1321  may be inserted into the sleeve hole  161 , and the rubber sleeve  16  may be mounted in the insertion hole  1244 . 
     d. providing lead terminals  1233 . The lead terminals  1233  may be inserted into the sleeve hole  161 , such that an exterior wall of the lead terminals  1233  presses the extending member  1231 . 
     In step d, an end of the extending member  1231  may be fixed, and the lead terminals  1233  may be inserted upwardly into the sleeve hole  161 , such that the extending member  1231  is tightly fixed between the lead terminals  1233  and the sleeve hole  161 . 
     In step c, the rubber sleeve  16  may be mounted upwardly into the insertion hole  1244 , such that the rubber sleeve  16  abuts against a top wall of the insertion hole  1244 . 
     In step b, the extending member  1231  may be moved downwardly to protrude from a lower surface of the bottom base  12 . After a lower portion of the E-liquid guiding body  131  is press-connected with the loading hole  1242 , the extending member  1321  may be pulled downwardly by a force, such that the E-liquid guiding body  131  tightly presses the loading hole  1242 . 
     After step d, the method may also include providing a pedestal  125 . The pedestal  125  may include a separator wall  1251  located at a lower portion. The separator wall  1251  may include a separator hole  1252 . A connecting chamber  1253  may be provided upwardly from a lower surface of the separator wall  1251 . A boss  1254  may extend upwardly from a top portion of the separator wall  1251  and bend inwardly. The boss  1254  may penetrate throughout a pedestal hole  1255  between top and bottom of the boss  1254 . The pedestal hole  1255  may be connected with the connecting chamber  1253 . The pedestal  125  may be disposed at an upper portion of the support member  124 , such that the separator hole  1252  is press-connected with the E-liquid guiding body  131 . 
     The present disclosure adopts a press-connection method to connect the heating wire  132  to the lead terminals  1233 , thereby realizing the connection between the heating wire  132  and the lead terminals  1233 . Using the tight pressing method, the security of the connection is significantly enhanced. The scenarios of falling off or separating of parts of the electronic cigarette under an external force can be avoided. The scenarios of the heating wire  132  and the lead terminals  1233  separating from one another caused by the assembling process and external forces can be effectively avoided. 
     The present disclosure also provides an atomization generating device manufactured with terminals mounted using the above-described press-connection method. 
     The air flow path according to some embodiments of the present disclosure can be briefly described as follows: 
     The external air may enter the snap-fitting hole  112  through the air inlet  211 , and enter the air guiding groove  1213  through the snap-fitting hole  112 . Then the external air may enter the first channel  1211  through the air guiding groove  1213 . The external air may then enter the second channel  1212 . The gas generated when the E-liquid is atomized by the atomizing core  13  may be guided to the cigarette mouthpiece  111  through the vapor channel  14 . Specifically, the E-liquid stored in the E-liquid storage tank  15  may be absorbed by the E-liquid guiding body  131 . The heating wire  132  may heat the E-liquid absorbed by the E-liquid guiding body  131  to atomize the E-liquid. The gas generated from the atomization may move upwardly to reach the connection chamber  1253 , and continue to move upwardly to enter the pedestal hole  1255 . The gas may then enter the bottom portion of the vapor channel  14 , and finally flow into the cigarette mouthpiece. 
     The air flow path according to other embodiments of the present disclosure can be briefly described as follows: 
     During smoking, the external air may enter the snap-fitting hole  112  through the air inlet  211 , and enter the air guiding groove  1213  through the snap-fitting hole  112 . The external air may then enter two first channels  1211  through the air guiding groove  1213 . One of the first channels  1211  may be connected with the third channel  1214 . The third channel  1214  may be connected with the first air guiding channel  2541 . The first air guiding channel  2541  may be connected with the air guiding tube  2422 . Thus, the external air may enter the first channel  1211 . When the pressure inside the first channel  1211  changes, the pressure inside the third channel  1214 , the first air guiding channel  2541 , and the air guiding tube  2422  may also change. Accordingly, the airflow sensor  241  may sense the change in the air flow. The airflow sensor  241  may transmit signals to the control assembly. The control assembly may control the operation of the atomizing core  13 , such as atomizing the E-liquid, based on the signals received from the airflow sensor  241 . When smoking is stopped, the pressure of the external air is the same as the pressure inside the first channel  1211 , the third channel  1214 , the first air guiding channel  2541 , and the air guiding tube  2422 . The airflow sensor  241  may not sense a change in the air flow. Hence, the control assembly may control the atomizing core  13  to stop atomizing the E-liquid. 
     The electrical circuit of the present disclosure can be briefly described as follows: 
     The battery  23  may be connected with the control assembly  24 , and connected with the connection terminals in the plastic member  25  through the control assembly  24 . The connection terminals may be connected with the lead terminals in the bottom base  12 . The lead terminals may be connected with the two ends of the heating wire  132  to provide electric energy to the heating wire  132 . The control assembly  24  may control the operation mode of the atomizing core  13 , such as the change in the heating power. The control assembly  24  may include an electrical circuit board. 
     The fluid path of the E-liquid according to the present disclosure can be briefly described as follows: 
     The E-liquid stored in the E-liquid storage tank  15  may be absorbed by the E-liquid guiding body  131 . The heating wire  132  may atomize the E-liquid absorbed by the E-liquid guiding body  131 . The excessive E-liquid on the E-liquid guiding body  131  may drip downwardly to enter the E-liquid storage gap  1261  between the exterior wall of the center rod  126  and the inner wall of the support member  124 , thereby avoiding the excessive E-liquid (condensed fluid) entering the second channel  1212 . When the E-liquid stored in the E-liquid storage tank  15  is consumed up, the E-liquid can first enter the E-liquid storage gap  1261  between the edge portion  127  and the support member  124 , and then be absorbed by two ends of the E-liquid guiding body  131 . 
     The above described are merely some embodiments of the present disclosure, which do not limit the scope of the present disclosure. Any modification, equivalent substitution, or improvement within the spirit and principle of the present disclosure fall within the scope of protection of the present disclosure.
