An inner wall of the one end of the oil cup 10 is formed with a gas guide 14 extending into the inside of the oil cup 10 at the edge of the air inlet 12, and the inside of the gas guide 14 is in communication with the air inlet 12. A liquid storage cavity 16 is formed between the gas guide 14 and the inner wall of the oil cup 10 to store atomization liquid. In the embodiment, the gas guide 14 and the oil cup 10 are integrally formed as a whole.

[0058] The atomization assembly comprises a top assembly, a bottom assembly and an atomization core 60. The top assembly comprises a seal 70 installed on the open end of the oil cup 10 and in sealing connection with the inner wall of the oil cup 10. The bottom assembly comprises a base 30 installed on the open end of the oil cup 10 and two electrodes 50 inserted into the base 30 and used to supply power to the atomization core 60. In the embodiment, the top assembly further comprises a bracket 40, one end (i.e. the bottom end of the bracket 40) of the bracket 40 is sleeved on the top end of the base 30, and the other end (i.e. the top end of the bracket 40) of the bracket 40 is installed in the seal 70. The inside of the bottom end of the bracket 40 is formed with a space for accommodating the atomization core 60, so that the atomization core 60 is clamped and positioned between the bracket 40 and the base 30.

[0059] Specifically, the outer wall of the sealing member 70 is formed with a plurality of annular protrusions 74 along the axial direction thereof, and the plurality of protrusions 74 elastically abut against the inner wall of the oil cup 10, so as to realize the sealed connection between the sealing member 70 and the inner wall of the oil cup 10. The sealing member 70 is provided with a liquid inlet 72, and the support 40 is provided with a liquid inlet channel 42 which is in communication with the corresponding liquid inlet 72, so that the atomization assembly is in communication with the liquid storage cavity 16 of the oil cup 10, and the atomized liquid in the liquid storage cavity 16 can be guided to the atomization core 60 through the liquid inlet channel 42.

[0060] The base 30 is provided with two mounting channels 38 (see Figure 3 ) which pass through the bottom end and the top end of the base 30 and are respectively close to the two sides of the base 30. The two electrodes 50 are respectively inserted into the two mounting channels 38 from the base 30 to the top assembly, so as to mount the two electrodes 50 to the base 30. The polarities of the two electrodes 50 are opposite. The bottom ends of the two electrodes 50 are preferably flush with the bottom end of the base 30, and the top ends of the two electrodes 50 respectively protrude from the top end of the base 30.

[0061] The atomization core 60 comprises a support body 62, a heating body 64 and an oil guiding body 66 which are sequentially stacked on the top end of the base 30. The heating body 64 is clamped and positioned by the support body 62 and the oil guiding body 66. The support body 62 supports the heating body 64. The oil guiding body 66 is mounted into the bottom end of the support 40 and tightly abuts against the bottom portion in the bottom end of the support 40. The oil guiding body 66 is in connection with the liquid inlet channel 42, and is used to guide the atomized liquid in the liquid storage cavity 16 to the heating body 64 to heat and atomize the atomized liquid by the heating body 64. Preferably, the outer wall of the oil guiding body 66 is in interference fit with the inner wall of the bottom end of the support 40. The two ends of the heating body 64 are respectively provided with first mounting holes 68b, and the two ends of the support body are respectively provided with second mounting holes 68a. The top ends of the two electrodes 50 are respectively riveted with the second mounting holes 68a at the two ends of the support body 62 and the first mounting holes 68b at the two ends of the heating body 64, and the two electrodes 50 are respectively electrically connected with the first mounting holes 68b of the heating body 64. Through this structure, the support body 62, the heating body 64 and the oil guiding body 66 of the atomization core 60 of the present application are sequentially stacked on the top end of the base 30. When assembling the atomization core 60, the support body 62 and the heating body 64 can be sequentially assembled on the top end of the base 30 of the bottom assembly. Then, the oil guiding body 66 is assembled into the bottom end of the support 40 of the top assembly, and the bottom end of the support 40 is sleeved on the top end of the base. The atomization core 60 of the present application can be automatically and batch assembled by an automatic riveting press, so as to improve the production efficiency and reduce the cost.

[0062] In other embodiments, the top ends of the two electrodes 50 can also be connected with the second mounting holes 68a at the two ends of the support body 62 and the first mounting holes 68b at the two ends of the heating body 64 by welding.

[0063] The heating element 64 is made of nickel, nickel-chromium, iron-chromium-aluminum, stainless steel, titanium or alloy, which can be selected according to actual conditions. The thickness of the heating element 64 is 0.03-0.15 mm, preferably 0.08 mm. The resistance of the heating element 64 is 0.3-2.0 ohm, preferably 1.1 ohm.

[0064] In the embodiment, the heating element 64 includes two sheet-shaped fixed parts 642 and an atomizing part 644 connected in series between the two fixed parts 642, and the two fixed parts 642 are respectively provided with the first mounting holes 68b.

[0065] The resistivity of the atomizing part 644 is greater than that of the fixed part 642. Understandably, the resistivity of the atomizing part 644 can also be the same as that of the fixed part 642.

[0066] In the embodiment, the atomizing part 644 is in a grid shape, which can ensure the atomizing area and ventilation and also ensure sufficient resistance. Understandably, the atomizing part 644 can also be in other forms, such as stripe shape, S shape, broken line shape, wave shape, zigzag shape, spiral shape, circle shape, rectangle shape, etc. The support body 62 is a dense ceramic piece. Understandably, the support body 62 can also be, for example, a porous ceramic piece, a silica gel piece, a metal piece with non-conductive outer surface, etc. In other embodiments, the support body 62 can also be a conductive piece, and the top end of the conductive piece is provided with an insulating piece to insulate the conductive piece and the heating element 64.

[0067] The support body 62 is provided with an airflow channel 622, which can be a hollow part or a hole part (see Figure 3 ) corresponding to the atomizing part 644. The hollow part or the hole part is in communication with the air inlet cavity 32 provided at the top end of the base 30. The bottom end of the base 30 is provided with an air inlet channel 34, and the bottom of the air inlet cavity 32 is provided with an air inlet hole 36 in communication with the air inlet channel 34. Therefore, external air can enter the atomizing part 644 through the air inlet channel 34, the air inlet hole 36, the air inlet cavity 32 and the airflow channel 622, and mix with the atomized gas mist heated by the heating element 64.

[0068] Preferably, the bottom 322 (see Figure 3 ) of the air inlet cavity is an arc surface protruding towards the air inlet cavity 32, which can prevent the condensed liquid or atomized liquid from entering the air inlet hole 36 and flowing out of the air inlet channel 34.

[0069] Preferably, as shown in Figure 4 , the atomizing part 644 is provided with two L-shaped first clamping parts 6444 on the two sides thereof, and the two first clamping parts 6444 on the two sides of the atomizing part 644 are clamped to the two sides of the support body 62 to support and better fix the heating element 64, so that the atomizing part 644 of the heating element 64 is not easy to deform and displace. There are a plurality of first clamping parts 644.

[0070] In an alternative, the first clamping portion 6444 is not arranged on both sides of the atomizing portion 644, and a supporting rib for supporting the heating body 64 is arranged inside the airflow channel 622, which also makes the atomizing portion 644 of the heating body 64 not easy to deform. The number of the supporting ribs is one or more, which can be arranged according to actual conditions.

[0071] Further, the top end of the base 30 is provided with a positioning block 39 on both sides of the air inlet cavity 32 to position the supporting body 62. Preferably, the positioning block 39 is four, and the four positioning blocks 39 are respectively located on the four corners of the air inlet cavity 32.

[0072] In the embodiment, the top end of each of the two electrodes 50 is flush with the top end of the heating body 64, and the top end of each of the two electrodes 50 is provided with a groove 52. The orifice of the first mounting hole 68b at each end of the heating body 64 is provided with a second clamping portion 646 extending towards the center of the corresponding first mounting hole 68b, the second clamping portion 646 is L-shaped, the second clamping portion 646 is clamped to the inner wall of the groove 52 of the corresponding electrode 50, which is conducive to the positioning of the heating body 64 and the heating body 64 not easy to deform, as shown in Figure 4 and Figure 5 When the second clamping portion 646 is not clamped to the inner wall of the groove 52 of the corresponding electrode 50, the second clamping portion 646 is strip-shaped, as shown in Figure 6 When the second clamping portion 646 is clamped to the inner wall of the groove 52 of the corresponding electrode 50, as shown in Figure 7 the heating body 64 is first stacked on the top end of the supporting body 62 and the first mounting hole 68b at each end of the heating body 64 is riveted to the two electrodes 50, and then the grooves 52 of the two electrodes 50 are punched by a punching tool, and the second clamping portion 646 at each end of the heating body 64 is bent to be L-shaped under the action of the punching force, thereby being clamped to the inner wall of the groove 52 of the corresponding electrode 50. Of course, the two electrodes 50 can also be electrically connected to the heating body 64 by welding.

[0073] The number of the second clamping portion 646 of each first mounting hole 68b is one or more, which can be arranged according to actual conditions. In the embodiment, the number of the second clamping portion 646 of each first mounting hole 68b is four, and the four second clamping portions 646 are uniformly arranged in the circumferential direction.

[0074] In an alternative, the top end of each of the two electrodes 50 protrudes from the top end of the heating body 64, which is also conducive to the positioning of the heating body 64 and the heating body 64 not easy to deform.

[0075] The oil guiding body 66 is a sheet-shaped structure and a single-layer structure. The material of the oil guiding body 66 is non-woven fabric, high molecular cotton or foamed oil-absorbing cotton, etc.

[0076] In one alternative, the oil guide 66 has a mesh structure and is a single-layer structure.

[0077] In one alternative, the oil-conducting body 66 has a multi-layer structure, including at least four non-woven fabric layers stacked together. The oil conduction rate of the non-woven fabric layer closer to the heating element 64 is greater than that of the other non-woven fabric layers. Among the two middle non-woven fabric layers, at least one of the non-woven fabric layers has a saturated oil absorption capacity per unit area greater than that of the other non-woven fabric layers. Therefore, the non-woven fabric layer farther from the heating element 64 can be selected from non-woven fabrics such as organic cotton or viscose fiber. The two middle non-woven fabric layers can be selected from non-woven fabrics with a large saturated oil absorption capacity per unit area (i.e., strong oil storage capacity) or mesh non-woven fabrics. The non-woven fabric layer closer to the heating element 64 can be selected from non-woven fabrics with a fast oil conduction speed, such as flax.

[0078] The thickness of each nonwoven fabric layer is 0.1-0.6 mm, preferably 0.3 mm. The basis weight of each nonwoven fabric layer is 30-120 g / m². 2 Preferably 60g / m 2 .

[0079] The liquid inlet channel 42 is provided between the bottom of the bracket 40 and the top of the bracket 40. The liquid inlet channel 42 corresponds to the fixing part 642. There are two liquid inlet channels 42, and the two liquid inlet channels 42 correspond to the two fixing parts 642 respectively.

[0080] Preferably, the width of the liquid inlet channel 42 gradually increases along the direction close to the liquid storage chamber 16 to increase the liquid inlet speed.

[0081] The top of the bracket 40 is provided with a first mounting position 44, and the bottom of the first mounting position 44 is provided with an air passage cavity 46, with open sides of the air passage cavity 46. Figure 3 As shown, at least one side of the oil guide body 66 is recessed to form an air passage groove 662. The air passage groove 662 corresponds to the atomizing part 644 and communicates with the corresponding side of the air passage chamber 46. Preferably, there are two air passage grooves 662, that is, the two sides of the middle of the oil guide body 66 are recessed to form two air passage grooves 662. The inner wall of the top end of the sealing member 70 is formed with a mounting part 76, which is installed into the first mounting position 44. The top end of the sealing member 70 is provided with a second mounting position 762, which passes through the bottom end of the mounting part 76. The end of the air guide member 14 away from the air intake 12 is installed into the second mounting position 762 and is sealed to the inner wall of the second mounting position 762. The interior of the air guide member 14 communicates with the air passage chamber 46. When the user inhales at the inlet 12, the external air entering the atomizing section 644 mixes with the aerosol heated and atomized by the heating element 64, and then enters the inlet 12 through the air groove 662, the air passage chamber 46, and the air guide 14, and is finally inhaled by the user.

[0082] The present invention also provides a method for assembling an atomizing component, comprising the following steps:

[0083] Step 1: Install the oil guide 66 into the bottom end of the bracket 40, ensuring that the oil guide 66 is tightly fitted to the bottom of the bracket 40. The oil guide 66 and the bottom end of the bracket 40 are interference-fitted.

[0084] The second step is to install the two electrodes 50 into the two mounting channels 38 of the base 30 respectively, and make the top ends of the two electrodes 50 protrude from the top end of the base 30 respectively, thereby forming the bottom assembly.

[0085] The third step is to stack the support body 62 onto the top of the base 30 and rivet the second mounting holes 68a at both ends of the support body 62 to the tops of the two electrodes 50. This step can be performed using an automated riveting machine.

[0086] Step 4: Stack the heating element 64 onto the top of the support 62 and rivet the first mounting holes 68b at both ends of the heating element 64 to the tops of the two electrodes 50. This step can be performed using an automated riveting machine, such as... Figure 8 As shown, the automated riveting machine includes an upper mold 210, an upper template 220 mounted on the upper mold 210, and a lower mold 230. The upper template 220 has a first mounting hole, and the lower mold 230 has a second mounting hole. In the actual assembly of the heating element 64, the heating element 64 is first assembled into the first mounting hole, and the base 30 of the support body 62, with the two electrodes 50 already installed, is assembled into the second mounting hole. Then, the riveting process is performed to assemble the heating element 64 onto the top of the support body 62.

[0087] The automated riveting machine enables the automated assembly of the heating element 64, and one automated riveting machine can complete the assembly of multiple heating elements 64 at one time, which greatly improves production efficiency and reduces production costs.

[0088] After the heating element 64 is assembled, the assembled base 30, support 62, and heating element 64 are first removed from the lower mold. Then, a stamping tool is used to align and stamp the grooves 52 of the two electrodes 50, causing the second locking portion 646 of the first mounting holes 68b at both ends of the heating element 64 to bend into an L-shape, thereby locking it into the inner wall of the groove 52 of the corresponding electrode 50. Figure 4 As shown.

[0089] Understandably, after the heating element 64 is assembled, it is not necessary to remove the base 30. A stamping tool can be directly installed on the upper template 220, and then the stamping tool can be used to stamp the grooves 52 of the two electrodes 50. Similarly, the second locking part 646 of the first mounting hole 68b at both ends of the heating element 64 can be bent into an L shape, thereby locking it into the inner wall of the groove 52 of the corresponding electrode 50.

[0090] Fifth step, the bottom end of the bracket 40 is sleeved to the top end of the base 30 and the oil guide body 66 is overlapped to the top end of the heating body 64. The way that the bottom end of the bracket 40 is sleeved to the top end of the base 30 is riveting and pressing.

[0091] Sixth step, the sealing piece 70 is sleeved to the top end of the bracket 40, and the atomization assembly is completed, as shown in Figure 2 .

[0092] After the atomization assembly is assembled, the atomization liquid is injected into the liquid storage cavity 16 of the oil cup 10 from the open end of the oil cup 10, the atomization assembly is installed to the open end of the oil cup 10, and the bracket 40 and the sealing piece 70 are located in the oil cup 10 and the sealing piece 70 is sealingly connected with the inner wall of the oil cup 10. The atomizer 100 is completed, as shown in Figure 1 .

[0093] The above-mentioned embodiments only express several embodiments of the present application, the description is more specific and detailed, but it cannot be understood as the limitation of the patent scope of the present application. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, several modifications and improvements can be made, which belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
