In addition, in the description of the present invention, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0094] Figure 1 It is an assembly schematic diagram of the e - cigarette provided by the embodiment of the present invention, Figure 2 It is a disassembly schematic diagram of the e - cigarette provided by the embodiment of the present invention, Figure 3 It is a cross - sectional schematic diagram of the e - cigarette provided by the embodiment of the present invention, as Figures 1-3As shown, the electronic cigarette in this embodiment includes an electronic cigarette rod B and an atomizer A detachably mounted on the electronic cigarette rod B. It is easy to understand that the atomizer A is a storage body for e-liquid. When the electronic cigarette works, the e-liquid in the atomizer A is heated and atomized, so that it can be inhaled by the user.

[0095] Figure 4 It is a schematic structural diagram of the atomizer A provided by an embodiment of the present invention. Figure 5 It is a schematic cross-sectional view of the atomizer A provided by an embodiment of the present invention. Figure 6 It is an exploded schematic diagram of the atomizer A provided by an embodiment of the present invention. As Figures 4-6 shown, the atomizer A in this embodiment includes a base 10, a terminal 20, and an atomization core 30. Specifically, Figure 7 It is a schematic structural diagram of the base 10 provided by an embodiment of the present invention. Figure 8 It is a schematic structural diagram of the base 10 from another perspective provided by an embodiment of the present invention. As Figures 7-8 shown, the base 10 is integrally arranged in a disc-shaped structure and includes opposite first end face a and second end face b. As an optional implementation manner, the base 10 is made of silica gel. Further, the base 10 has a through hole 101 penetrating from the first end face a to the second end face b, and a receiving groove 102 recessed from the second end face b toward the first end face a. It should be noted that in this embodiment, the through hole 101 functions for wiring and ventilation, and the receiving groove 102 is used to receive the terminal 20 so that the atomizer A is electrically connected to the electronic cigarette rod B through the terminal 20.

[0096] Specifically, Figure 9 It is a schematic structural diagram of the 20 terminal provided by an embodiment of the present invention. Combining Figure 9As shown, the terminal 20 is press-fitted and arranged in the accommodation groove 102, and includes a fixing portion 201 and a clamping portion 202 extending diffusely from one end of the fixing portion 201. It should be noted that the terminal 20 is made of copper or other materials with good electrical conductivity. In one embodiment, the accommodation groove 102 is arranged as a circular groove, and the fixing portion 201 is correspondingly arranged as a cylindrical shape. When the atomizer A is docked with the electronic cigarette rod B, the power supply terminal B1 of the electronic cigarette rod B extends into the fixing portion 201, that is, into the accommodation groove 102. Further, the clamping portion 202 is recessed from the end towards the fixing portion 201 to form a clamping groove 203. As an alternative embodiment, a part of the clamping groove 203 is located on the fixing portion 201. It should be noted that the number and position of the clamping grooves 203 can be set according to actual needs. In this embodiment, the number of the clamping grooves 203 is four, and they are evenly distributed on the clamping portion 202, and there is a certain distance between adjacent two clamping grooves 203. The clamping groove 203 can enable the power supply terminal B1 to be connected to the terminal 20, and through elastic deformation, the fixing portion 201 can be attached to the outer side surface of the power supply terminal B1. Moreover, the setting of multiple clamping grooves 203 helps the user to quickly clamp and fix with the terminal 20 during assembly to achieve the effect of quick assembly; when one of the clamping grooves 203 is damaged or deformed excessively after assembly or disassembly, there are other clamping grooves 203 to ensure the effectiveness of the connection.

[0097] Furthermore, Figure 10 is a schematic structural diagram of the atomization core 30 provided by the embodiment of the present invention. Combining Figure 10 As shown, the atomization core 30 is provided with pins 301. As an alternative embodiment, the atomization core 30 is selected from a ceramic atomization core, a cotton atomization core, a steel mesh atomization core, etc. that can achieve the heating function. The atomization core 30 is connected to the power supply terminal B1 of the electronic cigarette rod B through the pins 301, so that the e-liquid can be atomized by heating. Optionally, the pins 301 are made of copper or other materials with good electrical conductivity. In one embodiment, the pins 301 include a main body portion 3011, a turning portion 3012, and a connecting portion 3013. Among them, the main body portion 3011 passes through the through hole 101, the turning portion 3012 extends from the main body portion 3011 towards the accommodation groove 102, and the connecting portion 3013 extends from the turning portion 3012 into the accommodation groove 102. The pins 301 are bent through the turning portion 3012, so that the connecting portion 3013 can be arranged at a suitable position according to actual needs, so as to connect the connecting portion 3013 with the terminal 20, that is, connect with the power supply terminal B1 of the electronic cigarette rod B.

[0098] In this embodiment, the connecting portion 3013 passes through the card slot 203 and is fixed between the fixing portion 201 and the accommodating groove 102. In one implementation, a gap 204 penetrating the fixing portion 201 is formed at the bottom of a card slot 203 in a direction away from the clamping portion 202, and the length of the gap 204 is less than or equal to the depth of the card slot 203. The gap 204 enables the terminal 20 to undergo elastic deformation, and the length of the gap 204 affects the state of elastic deformation of the terminal 20. When the length of the gap 204 is less than or equal to the depth of the card slot 203, it is convenient for the terminal 20 to closely adhere to the inner wall of the accommodating groove 102 after being inserted into the accommodating groove 102, and it can ensure that the connecting portion 3013 is pressed by the terminal 20, preventing the pin 301 from falling off and causing the electronic cigarette to be unusable, so that the atomization core 30 can be stably electrically connected to the terminal 20. Thus, by pressing the pin 301 with the terminal 20, the soldering process is omitted, which not only saves labor but also facilitates automation and is beneficial to improving the process efficiency.

[0099] It should be noted that the atomization core 30 of this embodiment has two pins 301, the number of accommodating grooves 102 is correspondingly set to two, and the number of terminals 20 is correspondingly set to two. It should be further noted that when the terminal 20 is inserted into the accommodating groove 102, a card slot 203 faces the through hole 101 for arranging the pin 301.

[0100] In one implementation, the base 10 is recessed from the second end face b towards the first end face a to form a groove 105, and the through hole 101 penetrates from the first end face a of the base 10 to the bottom of the groove 105. It should be noted that the shape and size of the groove 105 can be set according to the position of the air outlet on the electronic cigarette rod B. In this implementation, the groove 105 helps the air flowing to the groove 105 enter the atomizer A through the through hole 101 by forming a larger space, and at the same time, the groove 105 also provides space for arranging the pin 301.

[0101] Furthermore, the base 10 is recessed from the second end face b to form a wire passing groove 106 communicating the accommodating groove 102 and the groove 105. When the pin 301 is bent and arranged, the turning portion 3012 is located in the wire passing groove 106, and the wire passing groove 106 plays a guiding and limiting role for the pin 301.

[0102] Furthermore, both ends of the wire passing groove 106 form slopes 107 towards the first end face a, and the inclination angle of the slopes 107 can be set to be greater than 2 degrees or match the bending angle of the turning portion 3012. It is easy to understand that the bending regions of the pin 301 extending from the main body portion 3011 to the turning portion 3012 and from the turning portion 3012 to the connecting portion 3013 are both guided and supported by the structural setting of the slopes 107.

[0103] Figure 11 FIG. Figure 11 is a schematic structural view of the holder 40 provided by an embodiment of the present invention. Figure 12 FIG. Figure 12 is a schematic structural view of the holder 40 from another perspective provided by an embodiment of the present invention. As Figures 11-12 shown, in one embodiment, the atomizer A further includes a holder 40. Specifically, both ends of the holder 40 are open to form a cavity. The first end of the holder 40 is fixedly disposed on the base 10 in alignment with the through hole 101. Further, the atomization core 30 is disposed in alignment with the cavity at the second end of the holder 40. Thus, the pin 301 can pass through the through hole 101 through the cavity. In addition, when a user uses the electronic cigarette, the air can continue to flow through the cavity of the holder 40 after passing through the through hole 101.

[0104] In one embodiment, the first end of the holder 40 is provided with an air passing hole 401 and a wire passing hole 402. Among them, the air passing through the through hole 101 can continue to flow through the air passing hole 401. The size of the wire passing hole 402 matches the main body portion 3011 of the pin 301. The pin 301 passes through the through hole 101 through the wire passing hole 402, and the wire passing hole 402 plays a certain fixing role on the main body portion 3011.

[0105] In one embodiment, the base 10 is recessed from the first end face a towards the second end face b to form a notch groove 103, and the through hole 101 penetrates through the bottom of the notch groove 103. Further, the first end of the holder 40 is fixedly disposed in the notch groove 103. It is easy to understand that the notch size of the notch groove 103 is small, and the first end of the holder 40 protrudes outward. Thus, the first end of the holder 40 cannot move longitudinally under the limitation of the notch groove 103, thereby achieving fixation. It should be noted that since the base 10 is made of silica gel, the holder 40 can be installed by being pushed into the notch groove 103 from the notch opening.

[0106] Figure 13 FIG. is a schematic structural view of the smoke guiding oil pipe 50 provided by an embodiment of the present invention. As Figure 13 shown, in one embodiment, the atomizer A further includes a smoke guiding oil pipe 50. Specifically, the pipe orifice of the smoke guiding oil pipe 50 is aligned with the opening at the second end of the holder 40, so as to ensure the flow of air. It should be noted that the smoke guiding oil pipe 50 is made of fibers or other materials that can permeate and adsorb smoke oil. When the electronic cigarette is used, the smoke oil adsorbed by the smoke guiding oil pipe 50 is atomized under the heating of the atomization core 30, and thus is inhaled by the user along with the air.

[0107] Further, Figure 14 FIG. Figure 14 is a schematic structural view of the bracket 60 provided by an embodiment of the present invention. As Figure 14As shown, the atomizer A further includes a bracket 60. Among them, the bracket 60 holds the holder 40 and the smoke guiding oil pipe 50 through a fixed connection, realizing the support and fixation of the smoke guiding oil pipe 50. As an alternative implementation, the bracket 60 is provided as a steel pipe and is sleeved outside the holder 40 and the smoke guiding oil pipe 50.

[0108] In one implementation, a guiding groove 601 is formed on the bracket 60. Correspondingly, a first convex portion 302 is formed on the atomizing core 30, and a second convex portion 403 is formed on the holder 40. By sliding the first convex portion 302 and the second convex portion 403 into the guiding groove 601, the relative fixation of the position between the atomizing core 30 and the holder 40 can be ensured, thereby ensuring the relative fixation of the position between the atomizing core 30 and the base 10, and avoiding the pins 301 being unable to pass through the wire passing hole 402 of the holder 40 and the through hole 101 of the base 10 due to misalignment.

[0109] Figure 15 is a schematic structural diagram of the oil storage cotton 70 provided by an embodiment of the present invention, as Figure 15 shown, in one implementation, the atomizer A further includes an oil storage cotton 70. Among them, the oil storage cotton 70 is sleeved on the holder 40 and the smoke guiding oil pipe 50, and the first end of the oil storage cotton 70 is attached to the first end face a of the base 10. As an alternative implementation, the oil storage cotton 70 is made of high molecular integrated cotton or other materials capable of adsorbing e-liquid. It is easy to understand that the e-liquid stored in the oil storage cotton 70 will be adsorbed by the smoke guiding oil pipe 50 under the action of osmosis for heating and atomization through the atomizing core 30.

[0110] Furthermore, Figure 16 is a schematic structural diagram of the end cap 80 provided by an embodiment of the present invention, Figure 17 is a schematic structural diagram of the end cap 80 from another perspective provided by an embodiment of the present invention, as Figures 16-17 shown, the atomizer A further includes an end cap 80. Among them, the end cap 80 covers the second end of the oil storage cotton 70. It should be noted that the end cap 80 is made of silica gel and has a certain elasticity, so it can pre-tightly fill the gap with the oil storage cotton 70 to prevent the e-liquid stored in the oil storage cotton 70 from leaking from the end cap 80. A guiding hole 801 is provided on the end cap 80, and the guiding hole 801 is aligned with the pipe orifice of the smoke guiding oil pipe 50. Thus, the atomized e-liquid and the air entering the atomizer A can continue to flow through the guiding hole 801.

[0111] Even further, Figure 18 is a schematic structural diagram of the oil absorption cotton 90 provided by an embodiment of the present invention, as Figure 18As shown, the atomizer A further includes an oil-absorbing cotton 90. The oil-absorbing cotton 90 is made of needle-punched cotton or other fiber materials that can adsorb e-liquid. The oil-absorbing cotton 90 is covered on the end cap 80. It should be noted that the oil-absorbing cotton 90 is provided with leakage holes 901, and the leakage holes 901 are aligned with the guide holes 801. Thus, through the leakage holes 901, it can be ensured that the atomized e-liquid and the air entering the atomizer A can continue to flow. In this embodiment, the oil-absorbing cotton 90 is used to adsorb the residual e-liquid through the surface tension of the internal voids to prevent e-liquid leakage.

[0112] In one embodiment, the end cap 80 is provided with a limiting groove 802, and the shape and size of the limiting groove 802 are mutually matched with the oil-absorbing cotton 90, and the oil-absorbing cotton 90 is arranged in the limiting groove 802. In this embodiment, the limiting groove 802 can prevent the oil-absorbing cotton 90 from shifting and affecting the anti-leakage effect.

[0113] In one embodiment, the end cap 80 is provided with a conduit 803. The guide hole 801 is located on the conduit 803, and the first end of the conduit 803 extends into the smoke guiding oil pipe 50. Thus, by providing the conduit 803, it is helpful for the user to inhale the atomized e-liquid.

[0114] Furthermore, the oil-absorbing cotton 90 is sleeved on the second end of the conduit 803 through the leakage holes 901. Specifically, the second end of the conduit 803 protrudes from the bottom of the limiting groove 802 and thus extends into the leakage holes 901. Thus, the conduit 803 can not only ensure the stable flow of the atomized e-liquid and the air entering the atomizer A, but also play a further role in fixing the oil-absorbing cotton 90.

[0115] Figure 19 is a schematic structural diagram of the outer cover 100 provided by an embodiment of the present invention, as Figure 19 shown, in one embodiment, the atomizer A further includes an outer cover 100. The outer cover 100 is made of PCTG, and the outer cover 100 is arranged in a cylindrical structure, and the shape and size are mutually matched with the oil storage cotton 70. It should be noted that PCTG is an amorphous copolyester, which has good viscosity, transparency and chemical resistance. The outer cover 100 is sleeved on the outside of the oil storage cotton 70, playing a supporting role for the oil storage cotton 70, and at the same time can also prevent e-liquid from leaking outwards. In addition, the transparent outer cover 100 is beneficial for the user to identify the remaining amount of e-liquid by observing the color change of the oil storage cotton 70, facilitating timely replacement of the atomizer A.

[0116] Further, the first end face a of the base 10 is recessed from the edge to form a first stepped structure 104.

As Figures 20-21 shown, in an embodiment, the atomizer A further includes a cigarette holder 110 with both ends open. The size of the cigarette holder 110 gradually decreases from the first end to the second end. The cigarette holder 110 is made of food-grade PC plastic or other materials. Among them, the opening at the first end of the cigarette holder 110 is larger so as to be sleeved on the end cap 80 for fixation. As an alternative embodiment, the opening at the first end of the cigarette holder 110 matches the outer cover 100, so that the first end of the cigarette holder 110 can be sleeved on the outer cover 100. As an alternative embodiment, the cigarette holder 110 can be fixed by means of a buckle or adhesion. Further, an air outlet pipe 1101 extends from the opening at the second end of the cigarette holder 110 towards the second end, and the air outlet pipe 1101 is aligned with the leakage hole 901. Thus, the atomized e-liquid and the air entering the atomizer A can be discharged through the air outlet pipe 1101, so that the user can inhale through the cigarette holder 110.

[0118] In an embodiment, a limiting portion 1102 is provided inside the cigarette holder 110, and the structure of the limiting portion 1102 matches that of the oil absorption cotton 90. After the cigarette holder 110 is installed, the limiting portion 1102 further limits the periphery of the oil absorption cotton 90 to prevent the oil absorption cotton 90 from shifting and affecting the anti-leakage effect.

As Figure 22As shown, in one embodiment, the atomizer A further includes a leak-proof plug 120. The leak-proof plug 120 is made of silica gel. The shape and size of the leak-proof plug 120 match the opening of the mouthpiece 110 and the air outlet pipe 1101, so that the leak-proof plug 120 can block the air outlet pipe 1101 from the second end of the mouthpiece 110, preventing the e-liquid from leaking from the mouthpiece 110 when the e-cigarette is not in use. As an alternative embodiment, protrusions are formed on the surface of the part of the leak-proof plug 120 extending into the air outlet pipe 1101, which can further enhance the leak-proof effect.

[0120] The embodiment of the present invention also provides an e-cigarette, which includes an e-cigarette rod B and an atomizer A. The structural features of the atomizer A are as described above and will not be elaborated here. In the e-cigarette of this embodiment, the atomizer A is detachably installed on the e-cigarette rod B, facilitating the replacement of the atomizer A. When the atomizer A is docked with the e-cigarette rod B, the power supply terminal B1 of the e-cigarette rod B is docked with the terminal 20 of the atomizer A, enabling the battery in the e-cigarette rod B to be electrically connected to the atomization core 30, realizing the heating and atomization of the e-liquid by the atomization core 30 to facilitate the user to inhale the atomized e-liquid.

[0121] The embodiment of the present invention provides an atomizer and an e-cigarette. The atomizer includes a base, a terminal, and an atomization core. The pins of the atomization core pass through the through holes on the base and are bent and extend into the accommodating groove on the base. The terminal is press-fitted in the accommodating groove and includes a cylindrical fixing part and a clamping part extending diffusely from one end of the fixing part. The clamping part is recessed from the end towards the fixing part to form a clamping groove. The pins of the atomization core pass through the clamping groove and are fixed between the fixing part and the accommodating groove. Thus, the atomizer can be formed only through simple assembly, saving the labor cost in the welding process, making automated operation feasible, and helping to improve the process efficiency.

[0122] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, various modifications and changes can be made to the present invention.
