[0051] In the electronic cigarette of the present application, the working installation position and the cartridge storage installation position penetrate the shell in the thickness direction of the shell, that is, the opposite sides of the working installation position and the cartridge storage installation position are in an open state, and the user can directly contact the cartridge to detach and install the cartridge, which is convenient to operate. When the user wants to switch the cartridge for inhalation, he only needs to swap the cartridges on the working installation position and the cartridge storage installation position, which is convenient to operate. The cartridge replacement method of the electronic cigarette of the present application includes: pushing the first cartridge out of the working installation position through the first push-out opening, pushing the second cartridge out of the cartridge storage installation position through the second push-out opening, and installing the second cartridge in the working installation position through the first installation opening. The cartridge replacement method of the electronic cigarette of the present application is simple and easy to operate, and is particularly suitable for electronic cigarettes equipped with more than two cartridges.

[0052] See also Figures 1 to 3 The electronic cigarette 100 of the present application includes a housing 110. The housing 110 is formed with a working installation position 120 in the thickness direction. The electronic cigarette 100 of the present application includes a first cigarette cartridge 140. The first cigarette cartridge 140 is detachably installed in the working installation position 120. The working installation position 120 has a first installation opening 121 and a first ejection opening 122 opposite to each other, that is, the opposite sides of the working installation position 120 are connected to the outside world.

[0053] When the first cigarette cartridge 140 is installed in the working installation position 120, the first cigarette cartridge 140 can atomize the cigarette oil. Figures 1 to 3 , the axial direction of the first cartridge 140 is perpendicular to the thickness direction of the shell 110, that is, both ends of the second cartridge 150 are connected to the working installation position 120. The electronic cigarette 100 of the present application includes a suction channel (not shown) and an electronic control device (not shown). The suction channel can guide and limit the flow of gas. The suction channel is formed in the shell 110, and the suction channel includes an air inlet section and an air outlet section. The air inlet section, the working installation position 120 and the air outlet section are connected in sequence. The electronic control device can control the atomization of the smoke oil in the cartridge. The electronic control device is arranged in the shell 110, and the electronic control device is exposed in the working installation position 120. When the first cartridge 140 is installed in the working installation position 120, the electrical connection end of the first cartridge 140 is connected to the electronic control device and is connected to the air inlet section, and the smoke outlet end of the first cartridge 140 is connected to the air outlet section.

[0054] See also Figures 1 to 3, two first connection grooves 123 are formed at the two ends of the working installation position 120 corresponding to the first cigarette cartridge 140, and the first connection groove 123 is formed by the side of the working installation position 120 facing the end face of the first cigarette cartridge 140, which is recessed in the direction away from the first cigarette cartridge 140, and one side of the first connection groove 123 extends to the first installation opening 121 and is connected to the first installation opening 121. When the first cigarette cartridge 140 is installed in the working installation position 120, the two ends of the first cigarette cartridge 140 are respectively sleeved in the two first connection grooves 123. The first cigarette cartridge 140 is connected to the working installation position 120 (specifically, it can be two first connection grooves 123) by snapping, bonding and / or magnetic attraction. As a result, the first cigarette cartridge 140 can be stably installed in the working installation position 120.

[0055] See also Figure 1 and Figure 2 The electronic cigarette 100 of the present application includes a seal 124, which is arranged in a first connection groove 123. The seal 124 is provided with an avoidance notch 125 for installing the first cigarette cartridge 140. The seal 124 is used to seal the electrical connection end of the first cigarette cartridge 140, the first connection groove 123 and the electronic control device. As a result, the oil in the first cigarette cartridge 140 is not easy to leak into the electronic control device, and the gas in the air intake section can also flow into the first cigarette cartridge 140 relatively well, so that the first cigarette cartridge 140 can have a relatively good atomization effect.

[0056] See also Figures 1 to 3 The shell 110 is formed with a cartridge storage installation position 130 in the thickness direction. The electronic cigarette 100 of the present application includes a second cartridge 150, which is detachably installed in the cartridge storage installation position 130. The cartridge storage installation position 130 has a second installation opening 131 and a second ejection opening 132 relative to each other, that is, the opposite sides of the cartridge storage installation position 130 are also connected to the outside world.

[0057] See also Figures 1 to 3 The working installation position 120 and the cartridge storage installation position 130 are arranged at intervals. Therefore, the detachment and installation of the first cigarette cartridge 140 and the second cigarette cartridge 150 do not interfere with each other, and the installation effect is better.

[0058] The second cigarette cartridge 150 can replace the first cigarette cartridge 140 and be installed in the working installation position 120. When the second cigarette cartridge 150 is installed in the working installation position 120, the electrical connection end of the second cigarette cartridge 150 is connected to the electronic control device and the air inlet section, and the smoke outlet end of the second cigarette cartridge 150 is connected to the air outlet section. Similarly, the first cigarette cartridge 140 can also replace the second cigarette cartridge 150 and be installed in the cartridge storage installation position 130.

[0059] See also Figures 1 to 3The first installation opening 121 and the second installation opening 131 are located on the same side of the housing 110. Thus, the direction of detaching and installing the first cartridge 140 is the same as the direction of detaching and installing the second cartridge 150, so that the first cartridge 140 and the second cartridge 150 can be easily interchanged.

[0060] See also Figures 1 to 3 When the second cigarette cartridge 150 is detachably mounted on the cartridge storage installation position 130, the axial direction of the second cigarette cartridge 150 is perpendicular to the thickness direction of the housing 110, that is, both ends of the second cigarette cartridge 150 are connected to the cartridge storage installation position 130. Therefore, when the first cigarette cartridge 140 and the second cigarette cartridge 150 are interchanged, there is no need to readjust the directions of both ends, so that the switching of cigarette cartridges is more convenient.

[0061] See also Figures 1 to 3 , two second connecting grooves 133 are respectively formed at the two ends of the second cartridge 150 corresponding to the cartridge storage mounting position 130, and the second connecting groove 133 is formed by a side of the cartridge storage mounting position 130 facing the end face of the second cartridge 150, which is recessed in a direction away from the second cartridge 150, and one side of the second connecting groove 133 extends to the second mounting opening 131 and is connected to the second mounting opening 131. When the second cartridge 150 is installed in the cartridge storage mounting position 130, the two ends of the second cartridge 150 are respectively sleeved in the two second connecting grooves 133. The second cartridge 150 is connected to the cartridge storage mounting position 130 (specifically, it can be two second connecting grooves 133) by snapping, bonding and / or magnetic attraction. As a result, the second cartridge 150 can be stably installed in the cartridge storage mounting position 130.

[0062] See also Figure 3 The end surface of the electrical connection end of the first cigarette cartridge 140 is recessed toward the smoke outlet end of the first cigarette cartridge 140 to form a plurality of avoidance grooves 141, which are arranged along the circumference of the electrical connection end and penetrate the circumferential side surface of the electrical connection end. When the first cigarette cartridge 140 is connected to the working installation position 120, the avoidance grooves 141 can avoid the electrodes of the electric control device, so that the electrodes will not be squeezed and bent, thereby avoiding the occurrence of poor electrical contact. Please refer to Figure 3 The electrical connection end of the second cigarette cartridge 150 is also provided with an avoidance groove 151 having a structure similar to the avoidance groove 141 .

[0063] See also Figure 1 and Figure 2In one embodiment, the electronic cigarette 100 includes two clamping rings 160. The two clamping rings 160 are arranged at the cartridge storage installation position 130 and are sleeved on the two ends of the second cartridge 150 in a one-to-one correspondence. The clamping rings 160 have an opening facing the second installation opening 131. The clamping rings 160 can be deformed so that the opening becomes larger under the action of an external force and recovers after the external force disappears. By setting the clamping rings 160, the stability of the second cartridge 150 installed in the cartridge storage installation position 130 can be enhanced.

[0064] See also Figure 3 In another embodiment, the electronic cigarette 100 includes an elastic connector 170. One end of the elastic connector 170 is fixedly connected to the cartridge storage installation position 130, and the other end of the elastic connector 170 abuts against the second cigarette cartridge 150. The elastic connector 170 can be deformed so that the two ends of the elastic connector 170 are close to or away from each other under the action of an external force and reset after the external force disappears. The elastic connector 170 can cooperate with the cartridge storage installation position 130 to improve the installation effect of the second cigarette cartridge 150 in the cartridge storage installation position 130.

[0065] See also Figure 1 and Figure 2 In one embodiment, the electronic cigarette 100 includes a sealing sheet 180. The sealing sheet 180 is disposed at the electrical connection end of the second cigarette cartridge 150, and the sealing sheet 180 is used to seal the air inlet hole opened on the electrical connection end. As a result, the smoke oil in the second cigarette cartridge 150 is not easy to leak from the air inlet hole.

[0066] See also Figure 1 and Figure 2 In one embodiment, the electronic cigarette 100 includes a sealing plug 190. The sealing plug 190 is plugged at the smoke outlet end of the second cigarette cartridge 150, and the sealing plug 190 is used to seal the smoke outlet end of the second cigarette cartridge 150. Therefore, the smoke oil in the second cigarette cartridge 150 is not easy to leak from the smoke outlet end.

[0067] The first cigarette cartridge 140 may also be provided with a sealing sheet 180 and a sealing plug 190, so that when the first cigarette cartridge 140 is not in use, the first cigarette cartridge 140 is in a state of being closed from the outside, thereby preventing the leakage of the cigarette oil inside it.

[0068] The flavor and / or power of the first cartridge 140 may also be different from the flavor and / or power of the second cartridge 150 , so that the electronic cigarette 100 of the present application can provide cartridges with different flavors and / or powers.

[0069] See also Figures 1 to 3 The number of the second cigarette cartridges 150 is at least two, and the at least two second cigarette cartridges 150 are arranged in the length direction of the housing 110. The flavors and / or powers of the at least two second cigarette cartridges 150 are different. Therefore, the electronic cigarette 100 of the present application can provide cigarette cartridges with multiple flavors and / or powers.

[0070] The surfaces of the first cartridge 140 and the second cartridge 150 are respectively provided with indicator marks, which include flavor, power size and / or installation direction, so that the user can easily identify and switch between different cartridges.
