[0025] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0026] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a cigarette cartridge magazine, which includes a main body 100, a heating core 200 and a fixing part 300; wherein, a heating space is provided in the main body 100, and a limiting cover 110 is formed at one end of the main body 100, and at least one airway hole 120 is provided on the limiting cover 110, and the outer surface of the limiting cover 110 is an arc-shaped surface 111; one end of the heating core 200 passes through the limiting cover 110 and extends into the heating space; the fixing part 300 abuts against the center part of the arc-shaped surface 111, and a gap 500 is formed between the fixing part 300 and the surrounding part of the center part, and the other end of the heating core 200 is fixedly connected to the fixing part 300.

[0027] It should be noted that the bottom of the existing cigarette cartridge magazine is flat, and the bottom of the cigarette cartridge magazine fits tightly with the heat-not-burn cigarette device. This causes a large gas flow resistance at the interface between the cigarette cartridge magazine and the heat-not-burn cigarette device, making it difficult for smoke to enter the mouth. As a result, the smoke concentration of each puff is much lower than that of traditional cigarettes, affecting the smoking taste.

[0028] To this end, in this embodiment, a gap 500 is formed between the limiting cover 110 having the curved surface 111 and the fixing member 300. An airway hole 120 is provided on the limiting cover 110, and the airway hole 120 is positioned at a position communicating with the gap 500. As a result, smoke emitted from the base 400 of the heat-not-burn cigarette can be temporarily retained in the gap 500 through the airway hole 120. During inhalation, the smoke retained in the gap 500 can compensate for the smoke concentration during a puff, making the smoke concentration of the heat-not-burn cigarette closer to that of a traditional cigarette, thereby improving the inhalation experience. The inner diameter of the heating space is larger than the diameter of the base 400, thereby forming a smoke flow channel 600 between the base 400 and the inner wall of the heating space. This channel 600 can communicate with the airway hole 120, thereby enhancing smoke fluidity and effectively reducing inhalation resistance.

[0029] It should be noted that the axis of the heating core 200 coincides with the axis of the main body 100, and the portion of the limiting cover 110 close to the heating core 200 can abut against the fixing member 300, and the abutting portion is the center portion of the limiting cover 110; and since the outer surface of the limiting cover 110 has an arc-shaped surface 111, and the surface of the fixing member 300 abutting against the limiting cover 110 is a plane, therefore, the position of the limiting cover 110 away from the above-mentioned center portion can form a gap 500 with the fixing member 300, that is, the position of the limiting cover 110 away from the above-mentioned center portion is the surrounding portion of the center portion.

[0030] Furthermore, the inner surface of the limiting cover 110 is an arc-shaped surface 111 , and the inner surface is concave toward the side away from the heating space.

[0031] Since the end surface of the base 400 is usually flat, when the heating core 200 is inserted into the base 400, the end surface of the base 400 will abut against the inner surface of the limiting cover 110, closing the airway hole 120, causing the channel 600 formed between the base 400 and the heating space to be unable to effectively communicate with the airway hole 120. To this end, in this embodiment, by making the inner surface of the limiting cover 110 recessed toward the side away from the heating space, a recessed space can be formed between the inner surface of the limiting cover 110 and the base 400. Compared with the end of the base 400 completely abutting against the inner surface of the limiting cover 110, when the end of the base 400 contacts the inner surface of the limiting cover 110, only the edge of the end of the base 400 contacts the limiting cover 110, and this contact is difficult to achieve completely sealed contact, that is, there is still a gap 500 for the smoke to flow into the above-mentioned recessed space, and then it can enter the above-mentioned gap 500 through the airway hole 120, thereby reducing the suction resistance.

[0032] In which, grooves can be provided on the inner surface of the limiting cover 110, and the grooves can be radiated from the edge of the limiting cover 110 to the center of the limiting cover 110. Therefore, when the end of the base 400 contacts the limiting cover 110, the smoke in the channel 600 can enter the above-mentioned recessed space through the grooves, and enter the above-mentioned gap 500 through the airway hole 120, thereby further reducing the suction resistance and improving the suction experience.

[0033] Furthermore, in order to ensure that the limiting cover 110 and the fixing member 300 are reliably in contact with each other, the central portion of the limiting cover 110 may be a plane.

[0034] It is understandable that, in order to facilitate the insertion of the heating core 200 into the heating space, a positioning hole 130 for inserting the heating core 200 may be provided on the central portion.

[0035] The positioning hole 130 may be provided with a keyway, and the heating core 200 may be provided with a key, and the key cooperates with the keyway to prevent the heating core 200 from rotating relative to the body 100 .

[0036] Furthermore, the fixing member 300 may be provided with an annular groove, and an annular protrusion may be provided on the central portion, and the annular protrusion is engaged with the annular groove.

[0037] When the limiting cover 110 is in abutment with the fixing member 300 , the annular protrusion on the center portion of the limiting cover 110 can be inserted into the annular groove of the fixing member 300 , thereby preventing radial shaking between the body 100 and the fixing member 300 .

[0038] Specifically, in order to effectively reduce the resistance to inhalation and improve the uniformity of smoke flow, the number of the airway holes 120 may be four, and the four airway holes 120 may be evenly distributed around the central portion.

[0039] The diameter of the airway hole 120 may be 1.1 mm to 1.3 mm; in this embodiment, it is preferably 1.2 mm.

[0040] An embodiment of the present invention also provides a heat-not-burn cigarette device, which includes a cigarette cartridge magazine provided by any embodiment of the present invention. The heat-not-burn cigarette device also includes a shell 700, in which an installation space and a heating component are provided. The cigarette cartridge magazine is fixedly arranged in the installation space, and the heating core is connected to the heating component.

[0041] The cigarette cartridge magazine and heat-not-burn cigarette device provided in the embodiments of the present invention form a gap between the limit cover with an arc-shaped surface and the fixing part, and at the same time, an airway hole is provided on the limit cover, so that the airway hole is set at a position connected to the above-mentioned gap. As a result, the smoke volatilized from the base of the heat-not-burn cigarette can be temporarily retained in the gap through the airway hole. When inhaling, the smoke retained in the gap can make up for the smoke concentration when taking a puff, so that the concentration of the heat-not-burn cigarette device when taking a puff is closer to that of traditional cigarettes, thereby improving the smoking experience.

[0042] The above describes in detail the structure, features and effects of the present invention based on the embodiments shown in the drawings. The above is only a preferred embodiment of the present invention, but the scope of implementation of the present invention is not limited to what is shown in the drawings. Any changes made in accordance with the concept of the present invention, or modifications to equivalent embodiments with equivalent changes, which do not exceed the spirit covered by the description and drawings, should be within the scope of protection of the present invention.
