As one of the key components of electronic cigarettes, the performance of the cartridge magazine directly affects the user's experience.

[0003] Early cartridge magazine designs are relatively simple, usually just a simple container, with limited fixing and supporting effect for cartridges. With the development of technology, some improved cartridge magazines have appeared, such as using simple card slot structure to fix the cartridge, but this way still has some problems in actual use, such as loose fixation, narrow airway space, high suction resistance, and high temperature of cartridge magazine wall due to heat loss of cartridge.

[0021] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative efforts under the premise that no creative efforts are made, belong to the scope of protection of the present application.

[0022] Commonly commercially available smoking sets generally use vertical strip-shaped protrusions in the cartridge to limit and support the cartridge, that is, the extension direction of the protrusions is parallel to the central axis of the cavity. After insertion, the cartridge locally deforms slightly inward at the position corresponding to the protrusions, the protrusions and the recesses fit together, and the cartridge is clamped in the cavity; but during subsequent heating, cooling and aerosol extraction, the cartridge will deform further, such as expansion and contraction, causing the recess of the cartridge to slightly loosen with the protrusions of the cavity, and when subjected to an external force parallel to the central axis, it is easy to slide, and even fall out of the cavity, affecting use. For example, the cartridge is occasionally taken out of the cavity in the case of sticking the filter segment to the mouth during use.

[0023] In some other product applications, the inner wall of the cavity of the smoking set uses a large-area contact to fix the side of the smoke pipe to increase the difficulty of sliding the cartridge, but it increases the suction resistance and makes it difficult to insert and pull out, and even the cartridge is pulled off after use.

[0024] Embodiment one

[0025] As shown in Figure 1 The cartridge with a cartridge fixing structure of the present application includes a cartridge body 1 and a fixed cap 2 in physical contact and cooperation, the cartridge body 1 is provided with a slot 11 for accommodating a cartridge, and the fixed cap 2 is provided with a hollow hole 21 corresponding to the slot 11; the inner wall of the hole 21 is provided with a plurality of inclined protrusions 23 and grooves 22 corresponding to the protrusions 23; when the cartridge 3 is accommodated, the protrusions 23 tightly abut the smoke pipe segment 31 of the cartridge 3, and the nozzle segment corresponding to the outer side of the smoke pipe segment 31 is used for suction during use; during use, the central axes of the cartridge body 1, the fixed cap 2 and the cartridge 3 are substantially coincident.

[0026] In order to solve the problem of loosening and sliding of the cartridge during use, the present application adopts the design of alternating cooperation of the grooves 22 and the protrusions 23, so that the cartridge 3 deforms inwardly when inserted, and the recess deformation geometry is in a non-parallel state with the central axis, and there is a certain intersection angle between the recess of the cartridge and the protrusions, forming a spiral (inclined) engagement. When the cartridge is subjected to an external force along the axial direction, the spiral protrusions can prevent the movement of the cartridge, so that it cannot easily slide. Specifically, each protrusion 23 and groove 22 forms an included angle 24 with the plane perpendicular to the central axis of the hole, denoted as β, preferably 5°<β<85°.

[0027] In the foregoing, the width of the protrusion 23 is greater than the width of the groove 22 (corresponding to the width of the circular arc), which facilitates providing appropriate holding force for the cartridge 3.

[0028] The height of the fixing cap 2 is less than the height of the groove 11, so that the fixing cap 2 is conveniently configured as a small component and can be detachably mounted on the cartridge holder body 1. According to different sizes of the cartridge, different sizes of the fixing cap 2 can be adjusted and replaced to adapt. While satisfying the requirement of limiting the movement of the cartridge 3 at the upper end of the cavity, the demolding process in the manufacturing process of the cartridge holder also needs to be considered. Therefore, in this embodiment, the cartridge holder is constructed as two components, i.e., the cartridge holder body 1 and the fixing cap 2. Considering the processing cost and assembly process, more components, for example, 3-5 components, can also be combined to form a cavity that can reasonably accommodate the cartridge 3. This is not different from the implementation manner of the present application and should be included in the scope of the present application. In the preferred scheme, the height of the fixing cap 2 is set to be, for example, 3 mm, and the maximum surrounding inner diameter of the protrusion 23 is slightly smaller than the outer diameter of the cartridge 3. The common outer diameter of the cartridge is 7.1 mm, so the surrounding inner diameter of the protrusion 23 is preferably set to 7 mm. In use, the cartridge holder body 1 is formed to accommodate the cartridge 3. Based on the common length of the cartridge being between 30-100 mm, the height of the groove 11 (receiving cavity) is set to be in the range of 20-50 mm in the present application, and the height of the fixing cap 2 is much smaller than the height of the groove 11.

[0029] The base material of the fixing cap 2 can be selected from resin, metal, ceramic or glass, which has excellent heat conduction performance on the one hand and is convenient for production and processing on the other hand. The fixing cap 2 is relatively thin, and the hole 21, the groove 22 and the protrusion 23 and other structures therein can be easily realized by injection molding, extrusion, sintering or numerical control processing forming process. The cartridge holder body 1 is configured as a cylinder, which has a high size, and engineering plastics such as polyether ether ketone (PEEK) or polyphenylene sulfide (PPS) are usually prepared by injection molding process.

[0030] In use, the fixing cap 2 is arranged at the corresponding position of the smoking set and is in close physical contact with the cartridge holder body 1. The user inserts the cartridge 3 into the accommodation, and the protrusion 23 of the fixing cap 2 abuts against the tobacco pipe section 31 of the cartridge 3 to form a slight deformation. Since the protrusion 23 is inclined, it generates horizontal and vertical components to fix the cartridge 3, forming a relatively stable positioning to prevent shaking. The formation of the groove 22 provides unobstructed conditions for internal airflow conduction, and since a stable and symmetrical airflow channel is constructed, even a consistent smoking experience can be ensured.

[0031] Further, in order to optimize air circulation and improve the use experience of the electronic cigarette, by adjusting the number, spiral angle and total length of the grooves, different performance requirements and design styles can be achieved to meet the diversified needs of the market. This is easily realized by adjusting the parameters based on the present application by those skilled in the art, and therefore the effects will not be described in detail.

[0032] In order to verify the use effect of the present embodiment, a SANS micro material universal testing machine was used for tensile test, the test speed was 150 mm / min, 5 samples were taken for test, and the average tensile force value was calculated. The typical relationship curve between tensile force and displacement in the test result is shown in Figure 2 The results show that the configuration in the present embodiment can maintain a high tensile force before and after suction, which can effectively fix the cartridge and prevent it from shaking or falling off during use. In addition, there is no phenomenon of the cartridge being pulled off during the test.

[0033] Embodiment Two

[0034] Referring to Figure 3 , on the basis of the previous embodiment, the groove 22 and the protrusion 23 structure of the fixing cap 2 are configured as a nut structure, that is, in a spiral shape. The spiral protrusion includes several thread structures, which are convenient for processing and forming. The upper surface of the fixing cap 2 adopts an inclined surface which is not perpendicular to the center axis of the hole 21, and cuts the thread structure, so that the upper end of the groove 22 exposes a plurality of openings which are in communication with the outside air, facilitating the airflow transmission during suction.

[0035] The maximum height of the fixing cap 2 is 6 mm, and the minimum height is 3 mm, wherein the tooth tip of the thread formed by the protrusion 23 is 7 mm, and 5-20 spirals are preferably configured. The width of a single protrusion is not greater than 10 mm, and the total length of the protrusion is not greater than 300 mm, and the length of the airway is as short as possible to realize the rapid flow of air.

[0036] Embodiment Three

[0037] In the present embodiment, the pull-out force of the cartridge under different configurations in the above two embodiments is evaluated. Group A and group B correspond to the cartridge settings in embodiment one and embodiment two respectively, and group C is a reference group, which selects a cartridge in a certain commercially available product, wherein a vertical rib protrusion with a height of 5 mm is used in the cavity. The same type of sheet heating non-combustion cartridge with an outer diameter of 7.1 mm is inserted into these cartridge holders, and before and after suction, a SANS micro material universal testing machine is used for tensile test, the test speed is 150 mm / min, 5 samples are taken for each test, and the average tensile force value is calculated. The test results are shown in Table 1. It can be found that the bearing tensile force of the present application is greater than that of the commercially available comparison group, which means that the risk of passive sliding or being taken out by the oral cavity is greatly reduced, but it can be pulled out after suction.

[0039] Sample group Average pull force (N) without suction Average pull force (N) after suction Group A 28.9 25.7 Group B 34.4 31.3 Group C 28.2 19.9

[0040] Following the previous points, the draw resistance of three configurations was tested, both before and after inserting the cartridge (in its fresh state) and after the sixth puff. The draw resistance testing equipment was a comprehensive electronic cigarette tester from Shenzhen Guangxin Electronics Co., Ltd., and the test conditions were set as follows: volume 35ml, flow rate 17.5ml / min, puff time 1.5 seconds, and puff interval 5 seconds. Under these test conditions, a draw resistance of less than 800Pa is considered within a comfortable range acceptable to the user.

[0041] The test results are shown in Table 2.

[0043] Sample group Resistance to draw (Pa) in fresh state Resistance to draw (Pa) at 6th draw Group A 762.3 722.4 Group B 788.5 762.3 Group C 701.2 678.2

[0044] The results showed that, in the fresh state and on the 6th puff, the draw resistance of groups A and B was slightly greater than that of group C, but still within an acceptable range. After heating and several puffs, the draw resistance of all three groups decreased to some extent, which is a normal and reasonable phenomenon. This also indicates that the airway was not blocked due to the heat deformation of the cartridge.
