[0058] The first aspect of the present invention provides a cigarette cartridge 100 for an electronic cigarette. Figure 1 , Figure 2 and Figure 3 The cigarette cartridge 100 includes an atomization device 110 , an end cover 130 and a conductive nail 150 .

[0059] The atomizer 110 has an air passage 117 that is arranged to pass through along a first direction D1 and a second direction D2, the first direction D1 is opposite to the second direction D2, an atomizer core 111 is arranged in the atomizer 110, and the atomizer core 111 is at least partially located in the air passage 117.

The atomizer core 111 has a heating element 112, and the heating element 112 has a conductive pin 114. The conductive pin 114 extends from the air passage 117 into the conductive cavity 119 around the partition wall 118. The end cap 130 is disposed on the side of the atomizing device 110 along the second direction D2, and is provided with a mounting hole 136 that penetrates along the first direction D1 and the second direction D2. The end cap 130 is also provided with a boss 135, the position of the boss 135 corresponds to the position of the partition wall 118 along the first direction D1, and the boss 135 presses the conductive pin 114 to the end of the partition wall 118 along the second direction D2. The conductive nail 150 is disposed through the mounting hole 136 and extends into the conductive cavity 119, and the conductive nail 150 abuts against the conductive pin 114.

[0060] According to the cigarette cartridge 100 of the present invention, the boss 135 provided on the end cover 130 is used to compress the conductive pin 114 to avoid damaging the atomizer core 111 by pulling the conductive pin 114 when assembling the conductive nail 150 .

[0061] The cartridge 100 further includes an oil cup 101, which is disposed on the side of the atomization device 110 along the first direction D1. As an optional embodiment, the first direction D1 may be the direction of the user's inhalation, and the second direction D2 may be the direction of the exhalation. Alternatively, when the central axis of the cartridge 100 is perpendicular to the horizontal plane, the first direction D1 may be upward, and the second direction D2 may be downward.

[0062] Specifically, the atomizer device 110 includes a first bracket 115, a second bracket 116, a first seal 120 and the above-mentioned atomizer core 111. Among them, the first bracket 115 and the second bracket 116 are both provided with through-holes, and the through-holes of the two are connected to form the above-mentioned air duct 117. The air duct 117 is connected to the smoking duct in the oil cup 101. The first seal 120 is sleeved on the first bracket 115, and the second bracket 116 is connected to the side of the first seal 120 along the first direction D1. The atomizer core 111 is arranged between the first bracket 115 and the second bracket 116. Among them, the atomizer core 111 includes a cotton core 113 and a heating element 112, and the heating element 112 is preferably configured as a heating wire, which is wound around the cotton core 113. The two ends of the heating wire extend to form conductive pins 114, which correspond to the positive and negative poles of the power supply respectively.

[0063] When the atomizer 110 is assembled, the oil cup 101 is sleeved on the outside of the atomizer 110. Preferably, a second seal 121 is provided between the outer periphery of the atomizer 110 and the oil cup 101. More specifically, a second seal 121 is provided between the outer periphery of the second bracket 116 and the oil cup 101. In addition, a transition bin is formed between the first bracket 115 and the second bracket 116, and the transition bin is connected to the oil bin of the oil cup 101. More specifically, the cotton core 113 of the atomizer core 111 is located between the first bracket 115 and the first seal 120, and the cotton core 113 extends into the transition bin. Among them, the smoke oil in the oil bin enters the transition bin and is absorbed by the cotton core 113, and then is atomized under the action of the heating element 112.

[0064] The end cover 130 includes a cover body 131 and a side wall portion 132, and the side wall portion 132 extends from the cover body 131 along the first direction D1. In addition, the two side walls 132 clamp the atomizing device 110 in the middle. The cover body 131 is provided with a receiving groove 133 with an opening toward the first direction D1, and the receiving groove 133 is connected to the air passage 117. An oil suction member 146 is provided in the receiving groove 133, and the position of the oil suction member 146 corresponds to the position of the air passage 117 along the second direction D2. The cover body 131 has an assembly surface 138 facing the first direction D1, and the end of the atomizing device 110 along the second direction D2 abuts against the assembly surface 138, for example, the end of the first bracket 115 along the second direction D2 abuts against the assembly surface 138. The cover body 131 is also provided with a gas flow channel 137 that passes through along the first direction D1 and the second direction D2, and the gas flow channel 137 is connected to the air vent 117, and the gas flow channel 137 and the air vent 117 are offset relative to the first direction D1. Therefore, the non-straight air channel design not only improves the suction effect, but also increases the available volume of the receiving groove 133, increases the volume of the oil suction member 146 that can be set, and improves the absorption effect of the condensate.

[0065] As a preferred embodiment, a part of the end cover 130 is also surrounded by the oil cup 101. In the embodiment shown in the figure, the cover body 131 partially extends into the oil cup 101, and only the bottom edge of the cover body 131 along the second direction D2 is exposed in the oil cup 101. And a third sealing member 122 is preferably provided between the oil cup 101 and the cover body 131 of the end cover 130. In addition, a fourth sealing member 102 is also provided between the through-hole of the first bracket 115 and the smoking duct of the oil cup 101 to form a more thorough seal. Thus, when the user inhales, the gas can enter the receiving groove 133 through the gas flow channel 137 of the end cover 130, and then enter the air passage 117 from the receiving groove 133, and then enter the user's mouth from the air passage 117 through the smoking duct of the oil cup 101.

[0066] refer to Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9 , the end cover 130 is provided with a mounting portion 134, specifically, the cover body 131 is provided with the mounting portion 134. Among them, the mounting portion 134 protrudes from the bottom wall of the accommodating groove 133, and the mounting portion 134 is provided with the above-mentioned mounting hole 136 and gas flow channel 137. As an implementation form, the above-mentioned assembly surface 138 is located on the side of the mounting portion 134 along the first direction D1, and the assembly surface 138 is adjacent to the inner wall surface of the mounting hole 136. The boss 135 is provided on the side of the mounting portion 134 along the first direction D1, and the boss 135 is adjacent to the mounting hole 136. The boss 135 protrudes from the assembly surface 138 along the first direction D1 to achieve the compression of the conductive pin 114. In addition, there is a gap between the boss 135 and the partition wall 118 to accommodate the conductive pin 114. Therefore, when the conductive nail 150 is assembled, the boss 135 can press the conductive pin 114 so that the conductive pin 114 can be fixed and prevented from pulling the cotton core 113 and causing the cotton core 113 to deform.

[0067] As a preferred embodiment, Figure 7 As shown, the height H of the boss 135 protruding from the assembly surface 138 is preferably 0.25-0.3 mm, thereby ensuring that the conductive pin 114 can be pressed tightly without causing assembly problems due to excessive interference.

[0068] refer to Figure 3 and Figure 4 , the side of the partition wall 118 facing the vent 117 is provided with a first limiting surface 123, the first limiting surface 123 is inclined in a direction away from the center of the vent 117, and the conductive pin 114 is at least partially in contact with the first limiting surface 123. The partition wall 118 is also provided with a second limiting surface 124 and a third limiting surface 125, wherein the second limiting surface 124 is adjacent to the first limiting surface 123, and the third limiting surface 125 is arranged toward the conductive cavity 119 and is adjacent to the second limiting surface 124, wherein the second limiting surface 124 is orthogonal to the first direction D1, and the third limiting surface 125 extends along the first direction D1. As an optional embodiment, when the first direction D1 and the second direction D2 are parallel to the vertical direction, the second limiting surface 124 can be a horizontal surface, and the third limiting surface 125 can be a vertical surface.

[0069] The conductive pin 114 includes a bending portion 126, and the bending portion 126 is in contact with the first limiting surface 123, the second limiting surface 124 and the third limiting surface 125, wherein the end of the conductive pin 114 is clamped between the conductive nail 150 and the third limiting surface 125. Specifically, the bending portion 126 includes a first bending section 127, a second bending section 128 and a third bending section 129, wherein the first bending section 127 is in contact with the first limiting surface 123, the second bending section 128 is in contact with the second limiting surface 124, and the third bending section 129 is in contact with the third limiting surface 125. Thus, the conductive pin 114 is configured to be partially in contact with the partition wall 118, which can improve the stability of the conductive pin 114, so that the conductive pin 114 can be in a stable state when the conductive nail 150 is not assembled, and further prevent the conductive pin 114 from moving when the conductive nail 150 is assembled.

[0070] Continue to refer Figures 5 to 9 The mounting portion 134 is also provided with an air guide surface 139, which is adjacent to the inner wall surface of the gas flow channel 137. The air guide surface 139 is recessed relative to the mounting surface 138 along the second direction D2 to form a first air guide groove 140, and the first air guide groove 140 is connected to the receiving groove 133. The side of the end cover 130 facing the second direction D2 is provided with a second air guide groove 141, which is recessed toward the first direction D1, and the second air guide groove 141 is connected to the gas flow channel 137. In this arrangement, when the user inhales, the gas first enters the gas flow channel 137 along the second air guide groove 141 from the side of the end cover 130 along the second direction D2, passes through the thickness of the cover body 131, and then enters the receiving groove 133 along the first air guide groove 140, and then enters the smoking passage of the oil cup 101 from the receiving groove 133 along the first direction D1 through the atomizer core 111. The multiple-curve air intake design improves the uniformity of air flow rate during suction and greatly improves the airflow sound produced during suction. In addition, the multiple-curve air intake design reduces the possibility of condensate flowing into the inlet during certain suction actions, thus improving the user experience.

[0071] As an implementation form, the periphery of the mounting hole 136 along the second direction D2 protrudes from the bottom wall of the second air guide groove 141 toward the second direction D2 to form a limiting flange 142. The conductive nail 150 includes a main body 151 and a limiting portion 152. The main body 151 extends into the mounting hole 136. The limiting portion 152 is located at the end of the main body 151 along the second direction D2, and the limiting portion 152 abuts against the limiting flange 142. Thus, the gas can enter the gas flow channel 137 from the gap between the conductive nail 150 and the cover body 131, that is, the above-mentioned second air guide groove 141.

[0072] The number of gas flow channels 137 is preferably set to four. The radial dimension of the gas flow channel 137 is preferably 0.6-0.7 mm. Specifically, two mounting portions 134 are preferably provided on the cover body 131, each mounting portion 134 is provided with a mounting hole 136 to correspond to the conductive nails 150 of the positive electrode and the negative electrode respectively, and two gas flow channels 137 are provided on each mounting portion 134.

[0073] The second air guide groove 141 is further provided with a limiting step portion 143, which is spaced apart from the limiting flange 142, and a step surface 144 of the limiting step portion 143 is flush with the end surface of the limiting flange 142, and the limiting portion 152 abuts against the end surface of the limiting flange 142 and the step surface 144. Thus, the assembly stability of the conductive nail 150 is improved.
