[0023] A cigarette rod 1 according to an embodiment of the present application will now be described with reference to FIGS. 1 to 4.

[0024] As shown in FIGS. 3 and 4, the cigarette rod 1 of the present application includes a housing 11, a bracket 12, a blocking member 14, and a microphone 15. The housing 11 defines an installation space 111. The installation space 111 has an insertion port 112. The installation space 111 in the housing 11 is used to receive a cartridge therein. The cartridge may be inserted into the installation space 111 through the insertion port 112.

[0025] The bracket 12 located in the housing 11 is used to support the cartridge. The bracket 12 is provided with a ventilation member 13. The ventilation member 13 defines an air channel 131. The air channel 131 connects an upper space above the bracket 12 to a lower space below the bracket 12. The air channel 131 has an air inlet 132 at an end of the air channel 131 facing the insertion port 112.

[0026] An inlet channel 133 is provided on an outer wall of the ventilation member 13. The inlet channel 133 communicates with the air channel 131. The blocking member 14 is located above the air inlet. After the cartridge is inserted into the installation space 111, condensate may generate on a surface of the cartridge during inhalations of a user. Since the blocking member 14 is located above the air inlet 132, after the condensate generates on the surface of the cartridge, the condensate will drop but not directly enter the air inlet 132. The blocking member 14 may block the air inlet 132, thereby preventing the condensate from entering the space below the bracket 12 through the air channel 131.

[0027] In related arts, a cigarette rod of an electronic cigarette is equipped with a microphone for sensing an airflow. A bracket is also installed in the cigarette rod to support a cartridge. A ventilation member, which communicates with spaces where the cartridge and the microphone are located, is provided on the bracket. After condensate on a surface of the cartridge or e-liquid leaks out, the condensate or e-liquid may flow into a space below the bracket through the ventilation member. Such liquid may cause damages to the microphone, resulting in failure of the cigarette rod.

[0028] In the present application, the blocking member 14 is located above the air inlet 132, the inlet channel 133 is formed on the outer wall of the ventilation member 13 and communicates with the air channel 131. Thus, the air inlet communicating the ventilation member 13 to the upper space of the bracket 12 is transferred to the side of the ventilation member 13. Thus, the condensate, which generates on the surface of the cartridge or e-liquid leaked from the cartridge, will not pass through the air inlet 132 at an end surface of the ventilation member 13 and fall into the lower space below the bracket 12. At the same time, the inlet channel 133 formed on the outer wall of the ventilation member 13 may maintain the ventilation effect of the ventilation member 13.

[0029] According to the cigarette rod 1 of the present application, the blocking member 14 is included, which is located above the air inlet 132 to prevent the condensate or e-liquid from dropping into the air inlet 132, thereby avoiding damages to the microphone 15 and improving the reliability of the cigarette rod 1. At the same time, the inlet channel 133 is formed on the outer wall of the ventilation member 13 and communicates with the air channel 131. The inlet channel 133 maintains a smooth airflow at the air inlet 132, so that air can flow between the upper space above the bracket 12 and the lower space below the bracket 12. Thus, the microphone 15 can detect corresponding parameters.

[0030] In some embodiments of the present application, the inlet channel 133 is a groove defined on the outer wall of the ventilation member 13. An air outlet of the inlet channel 133 communicates with the air inlet 132 of the air channel 131. The groove may extend along a vertical or periphery direction, thereby increasing an area of the groove facing the air. Thus, the air amount in the air channel 131 may be ensured. Furthermore, at least a portion of the inlet channel 133 further extends on a top end of the ventilation member 13 and then communicates with the air inlet 132 on the end surface of the ventilation member 13. Thus, even when the blocking member 14 is located above the air inlet 132, the inlet channel 133 may still communicates with the air inlet 132 to increase the air amount at the air inlet 132.

[0031] In some embodiments of the present application, the inlet channel 133 may also be constructed as a vent hole that penetrates the outer wall of the ventilation member 13. The vent hole directly communicates with the air channel 131.

[0032] In some embodiments of the present application, the inlet channel 133 may also be a groove extending along a straight line. The ventilation member 13 may be constructed as a cylindrical protrusion. The air channel 131 is defined in the cylindrical protrusion, and the air inlet 132 is formed on a top end of the cylindrical protrusion. The inlet channel 133 is constructed as a groove defined on the outer wall of the ventilation member 13. Thus, the process of the inlet channel 133 is facilitated, and the air amount at the air inlet 132 is increased. At the same time, it can prevent that the inlet channel 133 is partially blocked in the height mode, the bottom portion of the inlet channel 133 is spaced from the blocking member 13, so that the inlet channel 133 may still communicate with the atmosphere. Thus, the communication between the inlet channel 133 and the air inlet 132 is not obstructed, thereby ensuring a stable and smooth airflow in the cigarette rod 1.

[0033] In some embodiments of the present application, the blocking member 14 covers the top end of the ventilation member 13 facing the insertion port 112. The blocking member 14 may include a blocking portion, which may match the end surface of the ventilation member 13 in shape and resist against the end surface of the ventilation member 13. The blocking member 14 may further include an extension portion, which may be arranged on an outer edge of the blocking portion and extend toward the bracket 12. An inner surface of the extension portion may resist against the outer wall of the ventilation member 13, thereby allowing the blocking member 14 to stably install on the ventilation member 13.

[0034] By constructing the inlet channel 133 as a groove on the outer wall of the ventilation member 13 and arranging the extension portion to be spaced from the bottom portion of the inlet channel 133, the airflow can enter the air inlet 132 along the extension direction of the inlet channel 133.

[0035] In some embodiments of the present application, the blocking member 14 and the ventilation member 13 are connected by interference fit. Since the blocking member 14 and the ventilation member 13 are connected by interference fit, the blocking member 14 can be firmly installed on the ventilation member 13. An inner diameter of the extension portion may be constructed to be smaller than an outer diameter of the ventilation member 13, thereby allowing the extension portion to be clamped around the outer wall of the ventilation member 13.

[0036] In an embodiment of the present application, the blocking member 14 may be constructed as an elastic member. For example, the blocking member 14 may be constructed as a rubber member. Thus, the blocking member 14, which is elastically deformed, can connect to the ventilation member 13 by interference fit, thereby further improving the connection reliability between the blocking member 14 and the ventilation member 13.

[0037] As shown in FIG. 2, in some embodiments of the present application, the end surface of the bracket 12 facing the insertion port 112 defines a recess 121. The ventilation member 13 is a hollow cylindrical structure received in the recess 121. The recess 121 defined on the bracket 12 can ensure a smooth airflow. Since the cartridge is inserted into the cigarette rod 1 of the present application, ventilation is needed between the cartridge and the air member below the bracket 12, and a smooth airflow is also required in the upper space of the bracket 12. By defining the recess 121 on the end surface of the bracket 12 facing the insertion port 112, a gap suitable for the airflow can be generated between the cartridge and the bracket 12, thereby ensuring smooth inhalations of the electronic cigarette.

[0038] In an embodiment of the present application, the housing 11 defines an air inflow hole. The air inflow hole extends through the housing 11 in a thickness direction. The air inflow hole is located above the bracket 12.

[0039] In some embodiments of the present application, an inner sidewall of the recess 121 further includes an avoidance groove 122 for avoiding the blocking member 14. By arranging the avoidance groove 122 at the inner sidewall of the recess 121 for avoiding the blocking member 14, the installation of the blocking member 14 can be facilitated, thereby avoiding the interference between the blocking member 14 and the inner sidewall of the recess 121. At the same time, a volume of the recess 121 can be increased, thereby increasing the cross-sectional area of the gap for airflow.

[0040] In some embodiments of the present application, the bracket 12 is further provided with conductive structures 123. A top surface of the blocking member 14 does not exceed a top surface the conductive structure 123. When inserting the cartridge into the cigarette rod 1, the cigarette rod 1 needs to energize the cartridge. A bottom surface of the cartridge is provided with a power receiving position. When inserting the cartridge into the cigarette rod 1, the conductive structure 123 may directly be in contact with the power receiving position. By arranging the top surface of the blocking member 14 to be located below the top surface of the conductive structure 123, the interference between the blocking member 14 and the cartridge may be avoided, and a stable connection between the power receiving position of the cartridge and the conductive structure 123 may also be ensured.

[0041] In some embodiments of the present application, a battery and a control member are further provided in the housing 11. The battery, the control member, and the microphone 15 may be electrically connected to each other and installed below the bracket 12. The battery is electrically connected to the conductive structure 123 on the bracket 12, so that the battery may energizes the cartridge after the conductive structure 123 is in contact with the power receiving position at the bottom surface of the cartridge.

[0042] Furthermore, when the microphone 15 inside the cigarette rod 1 determines that the user inhales according to the detected airflow or air pressure signal, the control member connects the battery to the conductive structure 123. When the conductive structure 123 is electrically connect to the power receiving position at the bottom wall of the cartridge, the battery may energize a heating member in the cartridge. Thus, the e-liquid in the cartridge may be atomized.

[0043] An electronic cigarette of the present application will now be described.

[0044] The electronic cigarette of the present application includes a cigarette rod 1 and a cartridge. The cigarette rod 1 is constructed as the cigarette rod 1 described in any of the above embodiments. The cartridge is inserted into the housing 11 through the insertion port 112, and the cigarette rod 1 may energize the cartridge. Since the electronic cigarette of the present application includes the cigarette rod 1 described in any of the above embodiments, the microphone 15 in the electronic cigarette is not easily damaged, and the reliability of the electronic cigarette is improved.
