When the lower edge of the mounting portion 12 is located below the lower edge of the tip portion 22, the movement of the oil absorbing material 9 upward in the axial direction is restricted by the mounting portion 12 to ensure the correct placement of the oil absorbing material 9.
Referring to fig. 1 and 2, when the mouthpiece 1 is installed, the air between the housing 7 and the rod 2 flows from the lower edge of the notch 24 to the upper edge of the notch 24 at the position of the notch 24, and then is discharged through the hollow chamber of the mouthpiece 1, and as the mounting portion 12 is inserted between the housing 7 and the tip portion 22, when the length of the insertion of the mounting portion 12 exceeds the dimension of the notch 24 in the axial direction, the inner side wall of the mounting portion 12 and the outer side wall of the tip portion 22 enclose the air guide chamber 102 which is open at the upper end and closed at the lower end at the position of the notch 24, so as to block the discharge of the air between the housing 7 and the rod 2 through the notch 24, in order to ensure that the discharge of the air between the housing 7 and the rod 2 is as much as possible to ensure that the influence of the insertion of the mounting portion 12 on the air pressure between the housing 7 and the rod 2 is not enough to extrude the smoke oil, preferably, in, the size of the air-guide chamber 102 is greater than or equal to two thirds of the size of the tip end portion 22 so that as much air as possible is discharged between the housing 7 and the rod 2 during the mounting of the mounting portion 12. In addition, in order to avoid that the distance between the lower edge of the notch 24 and the lower edge of the top end portion 22 is too small, which affects the tightness of the connection between the mounting portion 12 and the top end portion 22, and causes the smoke to enter the air guide chamber 102 through the gap between the mounting portion 12 and the top end portion 22, and then to be discharged out of the smoke damper 1, the size of the air guide chamber 102 in the axial direction is preferably less than or equal to one sixth of the axial size of the top end portion 22, so as to ensure that the mounting portion 12 and the top end portion 22 have enough overlap completely and ensure the tightness of the connection therebetween. Further, the distance between the bottom wall of the air guide chamber 102 and the lower edge of the mounting portion 12 is greater than or equal to one sixth of the size of the tip portion 22, so as to better ensure that the mounting portion 12 and the tip portion 22 have a sufficient complete overlap, thereby better ensuring a tight connection therebetween.
In order to ensure that the gas in the housing 7 is better discharged when the mounting portion 12 is inserted, it is preferable that, as shown in fig. 1 and 2, the gas conducting chamber 102 has a size greater than or equal to one sixth of the size of the tip portion 22 in the circumferential direction of the tip portion 22, that is, by ensuring a sufficiently large gap 24, gas can be better discharged out of the cartridge through the gap 24, avoiding spillage of the tar due to untimely gas discharge. In addition, if the circumferential dimension of the air guide cavity 102 is too large, that is, the notch 24 is too large, which may result in an unreliable connection between the mounting portion 12 and the top end portion 22, it is preferable that the dimension of the air guide cavity 102 is less than or equal to one third of the dimension of the top end portion 22 in the circumferential direction of the top end portion 22, so as to ensure that the mounting portion 12 and the top end portion 22 have enough contact area at each position in the axial direction, ensure tight connection between the mounting portion 12 and the top end portion 22, and avoid the mounting portion 12 and the top end portion 22 from generating a gap at other positions except the position of.
The specific shape of the gap 24 is not limited as long as the gap 24 is not communicated with the hollow chamber of the top end portion 22, the lower end of the air guide chamber 102 formed between the inner side wall of the mounting portion 12 and the top end portion 22 is closed, and the upper end opening is communicated with the hollow chamber of the mouthpiece 1. For example, the notch 24 may extend from the upper edge to the lower edge in a spiral shape in the circumferential direction of the tip portion 22, or may extend straight in the axial direction of the rod member 2. When the spiral extends, the tightness of the pressing connection between the mounting part 12 and the top end part 22 can be better ensured, and the reliability of the connection of the top end of the cigarette bullet can be ensured; when the installation part 12 extends linearly, the air in the shell 7 can be discharged more conveniently in the process of inserting the shell 7, and the overflow of the tobacco tar can be better avoided.
Preferably, referring to fig. 1 and 2, the side wall of the air guide chamber 102 close to the axis of the rod 2 is a plane to facilitate the processing of the notch 24 of the tip portion 22, and further, the plane is parallel to the axis of the rod 2 to further facilitate the processing of the notch 24, for example, the tip portion 22 forms the notch 24 by cutting off part of the structure along the axis of the rod 2, so as to facilitate the production of the rod 2 and improve the production efficiency.
Alternatively, the cross section of the air-guide chamber is configured as an annular surface to better ensure the discharge of the gas, the radial dimension of which is gradually reduced from the upper edge of the tip portion 22 to the lower edge in the axial direction of the rod 2. That is, the radial dimension of the removed portion of the tip portion 22 near the end of the filter member 8 is large, and when the mounting portion 12 is inserted, a certain guiding function is provided, so that the insertion of the mounting portion 12 is facilitated, and the assembling efficiency is improved.
In one embodiment, referring to fig. 1 and 2, the tip portion 22 is a cylindrical structure, the number of the notches 24 is one, and the notch 24 partially extends linearly from the tip end of the tip portion 22 to a direction close to the intermediate portion 21 in the axial direction of the rod member 2, so as to facilitate the processing of the notch 24, and the dimension of the air guide chamber 102 in the circumferential direction of the tip portion 22 is smaller than one-half of the circumferential dimension of the tip portion 22, so as to ensure a tight connection between the mounting portion 12 and the tip portion 22. It should be noted that the number of the notches 24 may be multiple, for example, three notches 24 are provided, and the sum of the circumferential dimensions of the air guide cavity 102 formed by the three notches 24 at the tip end portion 22 is less than one half of the circumferential dimension of the tip end portion 22, so as to ensure the tightness of the connection between the mounting portion 12 and the tip end portion 22. Preferably, the plurality of notches 24 are evenly distributed in the circumferential direction of the tip portion 22, so that the gas in the housing 7 can be discharged when the mouthpiece 1 is attached, and the attachment portion 12, the tip portion 22, and the housing 7 can be tightly connected.
In an alternative, referring to fig. 1 and 3, instead of providing the notch 24 in the top end portion 22, an air guide channel 103 is provided in the top end portion 22, an air inlet of the air guide channel 103 is located on the outer side wall of the top end portion 22 (referring to the side wall away from the axis of the rod 2), an air outlet of the air guide channel 103 is located on the inner side wall of the top end portion 22 (referring to the side wall close to the axis of the rod 2) and/or the top wall of the top end portion 22 (referring to the end wall close to the mouth 11), and in the case where the oil storage space is filled with the smoke oil, during the insertion of the mounting portion 12 of the smoke cartridge nozzle 1 between the housing 7 and the top end portion 22, the air between the housing 7 and the rod 2 is compressed, and the air enters the air guide channel 103 of the top end portion 22 through the air inlet, then enters the flue 101 through the air outlet, and finally is discharged to the outside of, the tobacco tar between the shell 7 and the rod 2 overflows through the flue 101 under the action of air pressure, so that the overflow of the tobacco tar is perfectly avoided, and the installation of the cigarette bullet mouth 1 is more convenient. In addition, after the cigarette bullet is assembled, the air inlet is blocked by the mounting part 12 between the shell 7 and the top end part 22, so that the smoke oil can be effectively prevented from entering the air guide channel 103 through the air inlet, and the smoke oil can not flow out through the air guide channel 103, thereby better ensuring the normal use of the cigarette bullet.
Referring to figures 1 and 3, when the mouthpiece 1 is installed, gas between the casing 7 and the rod 2 enters the gas guide channel 103 from the gas inlet on the outer side wall of the tip portion 22, then exits through the gas outlet and then exits through the mouthpiece 1, and as the mounting portion 12 extends between the casing 7 and the tip portion 22, when the mounting portion 12 extends into a length exceeding the lower edge of the gas inlet, the mounting portion 12 blocks the gas inlet, thereby blocking the gas between the casing 7 and the rod 2 from exiting through the gas guide channel 103, in order to ensure that as much gas as possible exits between the casing 7 and the rod 2, to ensure that the insertion of the mounting portion 12 has insufficient effect on the gas pressure between the casing 7 and the rod 2 to squeeze out the tar, preferably, in the axial direction of the rod 2, the distance between the lower edge of the gas inlet and the bottom wall of the tip portion 22 (which means the end wall away from the mouth 11) is less than or equal to one third of the axial dimension of the tip portion 22, so that during the installation of the mounting portion 12, it is ensured that the air inlet remains unblocked by the mounting portion 12 for a certain period of time, as much as possible of the air between the housing 7 and the rod 2 being expelled.
