DETAILED DESCRIPTION

[0047] The description of the embodiments of this specification should be combined with the corresponding drawings, which should be considered as part of the complete specification. In the drawings, the shape or thickness of the embodiments may be enlarged and indicated for simplification or convenience. Furthermore, the parts of each structure in the drawings will be described separately. It is worth noting that the elements not shown in the drawings or not described in words are in a form known to ordinary technicians in the relevant technical field.

[0048] The description of the embodiments herein and any reference to directions and orientations are only for the convenience of description and are not to be construed as any limitation on the scope of protection of the present invention. The following description of the preferred embodiments may involve combinations of features, which may exist independently or in combination, and the present invention is not particularly limited to the preferred embodiments. The scope of the present invention is defined by the claims.

[0049] like Figures 1 to 7 As shown, the utility model proposes an electronic cigarette, comprising a mouthpiece 100, an upper shell 200 for mounting a heating device 202 and a cigarette cartridge 201, and a lower shell 300 for fixing a power source, which are arranged in sequence from top to bottom;

[0050] The upper shell 200 is provided with a mounting groove 203 inside; a rotating shaft 204 is provided between the cigarette holder 100 and the upper shell 200, and the rotating shaft 204 is provided on a side away from the mounting groove 203 and is located at a non-central position of the cigarette holder 100;

[0051] A first magnet 101 is disposed on the cigarette holder 100 at one side of the rotating shaft 204 close to the mounting groove 203, and a second magnet 205 is disposed at a corresponding position of the upper shell 200;

[0052] A positioning protrusion 206 is provided on the upper shell 200 on the side of the rotating shaft 204 away from the mounting groove 203, and a plurality of positioning grooves 102 adapted to the positioning protrusion 206 are provided around the rotating shaft 204 on the surface where the cigarette holder 100 contacts the upper shell 200, and the distance between the positioning protrusion 206 and the rotating shaft 204 is equal to the distance between any positioning groove 102 and the rotating shaft 204.

[0053] In this embodiment, a rotating shaft 204 is arranged between the cigarette holder 100 and the upper shell 200, and a mounting groove 203 is arranged in the upper shell 200. The mounting groove 203 is used to install the heating device 202 and the cigarette cartridge 201. The rotating shaft 204 is arranged on a side away from the mounting groove 203. The rotating shaft 204 is eccentrically arranged away from the center of the cigarette holder 100, so that the cigarette holder 100 and the upper shell 200 can achieve side sliding movement through the rotating shaft 204. After side sliding occurs between the cigarette holder 100 and the upper shell 200, the cigarette cartridge 201 is installed in the mounting groove 203 of the upper shell 200, thereby completing the replacement process of the cigarette cartridge 201 of the electronic cigarette. The electronic cigarette has a simple structure, and the replacement method of the cigarette cartridge 201 is novel and interesting.

[0054] A first magnet 101 is arranged on the mouthpiece 100, and a second magnet 205 is arranged at a corresponding position of the upper shell 200. After the cigarette cartridge 201 is replaced, the problem of random side sliding between the mouthpiece 100 and the upper shell 200 can be avoided by magnetic attraction, that is, the problem of the heated cigarette cartridge 201 sliding out can be avoided, thereby ensuring the safety and stability of the electronic cigarette.

[0055] A positioning protrusion 206 is set on the upper surface of the upper shell 200, which is adapted to the positioning groove 102 on the lower surface of the cigarette holder 100. The positioning groove 102 is adapted to the size of the positioning point. When the cigarette holder 100 slides sideways based on the rotating axis 204, the position is fixed by the positioning protrusion 206 and the positioning groove 102, avoiding the problem of the cigarette holder 100 restoring its position to block the installation of the cigarette cartridge 201 during installation, which is beneficial to improving the installation efficiency of the cigarette cartridge 201.

[0056] Specifically, the cross-section of any position of the cigarette holder 100, the upper shell 200 and the lower shell 300 is runway-shaped, the rotating shaft 204 is arranged at a position slightly to the left of the center of the cigarette holder 100, the positioning protrusion 206 is arranged on the left side of the rotating shaft 204, and the first magnet 101 is arranged on the right side of the rotating shaft 204; a plurality of positioning grooves 102 adapted to the positioning protrusion 206 are arranged on the lower shell 300 around the rotating shaft 204, and the distance from the center line of the positioning protrusion 206 to the center line of the rotating shaft 204 is equal to the distance between the center line of the positioning groove 102 and the center line of the rotating shaft 204, so as to ensure that the positioning protrusion 206 can accurately enter the positioning groove 102 when the cigarette holder 100 slides sideways based on the rotating shaft 204.

[0057] It is understandable that the height of the positioning protrusion 206 is relatively small and does not affect the side sliding process of the cigarette holder 100 .

[0058] In some embodiments of the present invention, the number of the positioning grooves 102 is three, and the angle between the line connecting two adjacent positioning grooves 102 and the rotation axis 204 is 90°.

[0059] In this embodiment, the number and position of the positioning grooves 102 represent the position where the cigarette holder 100 stops sliding sideways. When the above conditions are met, the triangle formed by the three positioning grooves 102 is an isosceles right triangle. When the positioning protrusion 206 is located in the middle positioning groove 102, the cigarette holder 100 is closed, and the first magnet 101 and the second magnet 205 are attracted and fixed to each other; when the positioning protrusion 206 is located in the other two positioning grooves 102, the cigarette holder 100 is opened, and the operation of replacing the cigarette cartridge 201 can be completed at this time.

[0060] like Figure 6 and Figure 7 As shown, in some embodiments of the utility model, it includes a cigarette cartridge body 21, which is provided with an inner cavity 22 for filling tobacco, a head 23 is provided at one end of the cigarette cartridge body 21, and the other end is an open end 24, and the connection between the cigarette cartridge body 21 and the head 23 is a rounded structure 25, the head 23 includes an outer ring connecting part 23a and an inner ring heating part 23b, the inner ring heating part 23b is recessed toward the inner side of the cigarette cartridge body 21, and a plurality of micro through holes 26 are provided on the inner ring heating part 23b.

[0061] The cigarette cartridge 201 is used in conjunction with the heating device 202. The cigarette cartridge 201 includes a cigarette cartridge body 21 and an inner cavity 22 in the cigarette cartridge body 21. The inner cavity 22 is used to fill tobacco. A sealing head 23 is provided at one end of the cigarette cartridge body 21, and the other end is provided as an opening. The sealing head 23 and the cigarette cartridge body 21 can be integrally formed for easy processing. During use, the sealing head 23 contacts the heating part, and the tobacco in the inner cavity 22 is heated by the heat conduction of the sealing head 23, and the smoke generated by evaporation overflows through the opening end 24.

[0062] By recessing the inner ring heating portion 23b of the seal 23 toward the inside of the cartridge body 21, a convection cavity is formed between the seal 23 and the heating portion, which can effectively avoid the problem of blockage of the micro-through holes 26 caused by complete fitting, thereby improving the heating efficiency, which is beneficial to the rapid increase of the temperature of the inner cavity 22 of the cartridge 201, improving the heating efficiency, and also improving the power supply endurance.

[0063] The cigarette cartridge body 21 is made of metal material and can be manufactured in one piece, which is easy to produce. During the heating process, heat can be quickly conducted through the inner circle heating part 23b and the side wall of the cigarette cartridge body 21, thereby improving the heating rate and uniformity of the unit tobacco, achieving the purpose of quickly increasing the temperature inside the cigarette cartridge 201, and further improving the utilization rate of the tobacco material.

[0064] One end of the cigarette cartridge body 21 is provided with a sealing head 23, and the other end is set as an opening, so that the smoke generated by the tobacco in the cigarette cartridge 201 can quickly overflow through the opening end 24, thereby achieving the purpose of quickly heating out the smoke, ensuring the smoke concentration, and improving the user experience.

[0065] The direction of the cigarette cartridge 201 can be identified by the depression of the inner ring heating part 23b toward the inner side of the cigarette cartridge body 21. There is no need to set a limit on the outer side of the side wall of the cigarette cartridge 201, thereby avoiding the limit of the cigarette cartridge 201 installation bin scratching the cigarette cartridge 201.

[0066] The connection between the cigarette cartridge body 21 and the sealing head 23 is a rounded structure 25, which is conducive to the rapid assembly of the cigarette cartridge 201.

[0067] It is understandable that a small amount of gel can be applied to the micro through-holes 26 of the cigarette cartridge 201, and the taste of the smoke produced by the tobacco can be adjusted by adjusting the smell of the gel to enhance the user experience.

[0068] In some embodiments of the present invention, the inner ring heating portion 23b is recessed into the inner side of the cigarette cartridge body 21 to a depth of 0.1 to 0.5 mm.

[0069] The gap between the inner ring heating part 23b of the head 23 and the heating part of the electronic cigarette device or other heating type device is crucial. If the gap size is too large, the heat conduction will be slow, and if the gap size is too small, the heat radiation and hot air flow will be poor, resulting in excessive local temperature. When the depth of the inner ring heating part 23b recessed into the inner side of the cartridge body 21 is 0.1 to 0.5 mm, the optimal heating efficiency is achieved, while the strength of the cartridge 201 can be met and it is also easy to install.

[0070] The working temperature for evaporation of the effective ingredients of tobacco is between 160°C and 260°C. Based on this, 180°C is taken as the standard. The following explanation is based on the specific data in Table 1, wherein time t refers to the time required for the temperature inside the cigarette cartridge 201 to reach 180°C from room temperature (20°C), and depth D refers to the depth of the inner circle heating part 23b recessed into the inner side of the cigarette cartridge body 21.

[0071]
