[0030] The electronic atomization device 300 includes a host 200 and an atomizer 100 . The host 200 is detachably connected to the atomizer 100 and supplies power to the atomizer 100 .

[0031] The atomizer 100 includes a shell assembly 10, an atomizer core 20 and an atomizer base 30. The shell assembly 10 is provided with a liquid storage chamber for storing an aerosol matrix. The atomizer core 20 is installed in the shell assembly 10.

The atomizer base 30 connects the shell assembly 10 and the atomizer core 20 to connect the shell assembly 10, the atomizer core 20 and the atomizer base 30 together. The atomizer base 30 can cover the liquid storage chamber of the shell assembly 10 and is provided with an air hole for connecting the aerosol channel of the atomizer core 20.

[0032] See also Figures 2 to 5 ,in Figure 3 yes Figure 2 The schematic diagram of the exploded structure of the atomizer shown in FIG. Figure 4 yes Figure 2 The schematic diagram of the structure of the nozzle in the atomizer is shown in FIG. Figure 5 yes Figure 2 A schematic structural diagram of the shell assembly in the atomizer shown.

[0033] In this embodiment, the shell assembly 10 includes a nozzle 12 and an atomizer shell 14, the nozzle 12 includes a face cover 120 and a vent pipe 122 connected to one side of the face cover 120, the atomizer shell 14 includes a tube shell 140 and a first partition plate 142 connected to the inner wall surface of the tube shell 140, the face cover 120 and one end of the tube shell 140 are fused by in-mold injection molding, the first partition plate 142 and the nozzle 12 are fused by in-mold injection molding to separate the space in the tube shell 140 into a first liquid storage tank 101 and a second liquid storage tank 102, and the vent pipe 122 is located in the second liquid storage tank 102, and the side wall of the second liquid storage tank 102 is provided with a liquid hole 103 connected to the first liquid storage tank 101; the atomizer core 20 is arranged in the second liquid storage tank 102 and connected to the vent pipe 122.

[0034] like Figure 4 As shown, a ventilation pipe 122 is provided on one side of the face cover 120 facing the atomizing housing 14, and the ventilation pipe 122 is connected to a suction nozzle pipe 124 on the face cover 120, and the suction nozzle pipe 124 is used for the user to inhale, wherein the suction nozzle 12 is a plastic part and can be formed by injection molding or compression molding.

[0035] like Figure 2 , Figure 3 and Figure 5As shown, the tube shell 140 can be a tube body of various shapes such as a directional tube or a circular tube, and the first partition 142 is semi-annular and connected to the inner wall surface of the tube shell 140, thereby separating the space of the tube shell 140 into two independent spaces, that is, separating into two independent spaces of the first liquid storage tank 101 and the second liquid storage tank 102, wherein the tube shell 140 and the first partition 142 are relatively straight tube-shaped. This structural feature will be conducive to the molding of the atomization shell 14, and the corresponding model mold has low complexity and low cost, which can save manufacturing costs and reduce production time.

[0036] See also Figure 5 , the face cover 120 is welded to one end of the tube shell 140 by in-mold injection molding, so as to be combined into one body. It can also be understood that since the face cover 120 is softened by high temperature in the mold of the tube shell 140, it is more tightly welded with the slurry of the injection-molded tube shell 140, and the sealing effect of the welding position is better, and the face cover 120 and the tube shell 140 are combined into one body; at the same time, the first partition plate 142 can be welded to the face cover 120 of the suction nozzle 12 by in-mold injection molding, or welded to other features on the suction nozzle 12 by in-mold injection molding, so as to form an integrated structure with the suction nozzle 12 and the atomizer shell 14, and the suction nozzle 12 and the atomizer shell 14 are welded by in-mold injection molding. The connection between the shells 14 does not require embedded assembly, but is sealed by abutting welding, so that the sealing effect between the suction nozzle 12 and the atomizing shell 14 is better, forming an integrated molding structure, and avoiding the phenomenon of poor sealing effect caused by assembly error; and the space in the tube shell 140 can be divided into a first liquid storage tank 101 and a second liquid storage tank 102 independent of each other through the first partition plate 142, and the ventilation pipe 122 is located in the second liquid storage tank 102, and the side wall of the second liquid storage tank 102 is provided with a liquid hole 103 connected to the first liquid storage tank 101, that is, the first liquid storage tank 101 can supply liquid to the second liquid storage tank 102 through the liquid hole 103 to replenish the aerosol matrix to the second liquid storage tank 102.

[0037] like Figure 2As shown, when the atomizer 100 is in use, the atomizer core 20 consumes the aerosol matrix in the second liquid storage tank 102; wherein the atomizer 100 is in an upright position when in use, and the liquid hole 103 is usually above the liquid level of the first liquid storage tank 101 and the second liquid storage tank 102, so that the aerosol matrix in the first liquid storage tank 101 and the second liquid storage tank 102 are isolated, and the heat emitted by the atomizer core 20 during operation affects the aerosol matrix in the second liquid storage tank 103, and under the influence of a long time, there is a risk of deterioration of the aerosol therein, and the first partition plate 142 can avoid possible deterioration. The aerosol matrix enters the first liquid storage tank 101, and can also block and weaken the heat transferred to the aerosol in the first liquid storage tank 101, thereby greatly reducing the risk of aerosol deterioration in the first liquid storage tank 101; the user can tilt or invert the atomizer 100 to allow the aerosol in the first liquid storage tank 101 to enter the second liquid storage tank 102 to replenish the second liquid storage tank 102, and the aerosol matrix that is not affected and has a good taste quality can be replenished into the second liquid storage tank 102, so that the taste of the aerosol generated by the atomization core 20 can be maintained at a high quality, eliminating the odor caused by the deteriorated aerosol.

[0038] The capacity of the first liquid storage tank 101 is greater than that of the second liquid storage tank 102. The first liquid storage tank 101 is relatively large in capacity, while the second liquid storage tank 102 is small in capacity. In addition, an atomizer core 20 is also provided in the second liquid storage tank 102, so that the capacity of the aerosol matrix that can be stored in the second liquid storage tank 102 is greatly reduced. For example, the capacity of the first liquid storage tank 101 is 15 ml, and the storage capacity of the second liquid storage tank 102 is 1 ml or 2 ml, etc., so that most of the aerosol matrix can be stored in the first liquid storage tank 101 without being affected by the atomizer core 20, and the unaffected aerosol can be replenished into the second liquid storage tank 102 at any time and multiple times to provide users with an unspoiled taste.

[0039] The suction nozzle 12 and the atomizer shell 14 are sealed by in-mold injection welding. Specifically, the molded suction nozzle 12 is placed in the mold of the atomizer shell 14, and the atomizer shell 14 is directly welded to the end of the surface cover 120 of the suction nozzle 12 during molding. In this way, the connection structure and the sealing structure can be eliminated, and no sealing ring is required, which also saves the assembly cost of this step, can effectively improve the production efficiency, and has a better sealing effect.

[0040] Optionally, the formed suction nozzle 12 and the formed atomizing shell 14 may be connected as one body through molten slurry, and the suction nozzle 12 and the atomizing shell 14 are both cast by the same molten slurry.

[0041] Optionally, one end of the first partition 142 facing the surface cover 120 may be higher than or flush with the end surface of the tube shell 140, and then the first partition 142 may be directly welded to the surface cover 120, wherein the first partition 142 is provided with a liquid hole 103, so that the structure of the suction nozzle 12 is relatively simple, and the mold structure for making the suction nozzle 12 is also relatively simple and low-cost, which helps to simplify the structure of the suction nozzle 12.

[0042] In this embodiment, Figure 4 and Figure 5 As shown, one end of the first partition 142 facing the face cover 120 is lower than the end surface of the tube shell 140, and the suction nozzle 12 also includes a second partition 126 connected to one side of the face cover 120, the second partition 126 is arranged semi-surrounding the ventilation pipe 122, the second partition 126 is at least partially fused with the first partition 142 by in-mold injection, the second partition 126 is provided with a liquid hole 103, and / or the second partition 126 and the tube shell 140 The liquid hole 103 is formed, and / or the first partition 142 and the second partition 126 cooperate to form the liquid hole 103.

[0043] The second partition plate 126 is provided with the above-mentioned liquid hole 103 , and the second partition plate 126 can be welded with the first partition plate 142 and the side wall of the tube shell 140 . The first partition plate 142 and the second partition plate 126 constitute the side wall of the second liquid storage tank 102 . By providing the second partition 126 and arranging the liquid hole 103 on the second partition 126, the structure of the atomizing shell 14 can be relatively simplified, without having to provide the liquid hole 103 on the first partition 142. During the injection molding process, it is easier to demold the atomizing shell 14 from the mold to avoid the phenomenon of being unable to demold due to undercutting, thereby making the mold and manufacturing process of the atomizing shell 14 simpler and more efficient. The length of the second partition 126 does not need to be set very long, and its length can be set to be less than or equal to the length of the ventilation pipe 122. Therefore, when molding the suction nozzle 12, it is easier to demold, the manufacturing process is simple, and the cost is reduced. Therefore, the second partition 126 and the liquid hole 103 are integrated on the suction nozzle 12, the molding process is simple, and the cost is reduced. From the overall perspective of the shell assembly 10, such a setting can facilitate welding and effectively reduce the manufacturing cost, save manufacturing time, and improve manufacturing efficiency.

[0044] Optionally, the second partition 126 can be welded only to the first partition 142, and the liquid hole 103 is formed by the gap formed between the edge of the second partition 126 and the inner wall of the tube shell 140, thereby avoiding the need to set the liquid hole 103 on the second partition 126 or the first partition 142, relatively reducing the area required for welding, and further simplifying the welding production process.

[0045] Optionally, at least one of the ends of the first separator 142 and the second separator 126 that are welded together is provided with a notch, and the notch constitutes the liquid hole 103 .

[0046] Furthermore, if Figure 2 and Figure 3 As shown, the housing assembly 10 further includes a decorative cover 16 , which can be bonded or snapped onto the nozzle 12 . The decorative cover 16 can be made of environmentally friendly materials, and its surface can be decorated with graphics, colors, or patterns.

[0047] See also Figure 2 and Figure 3 The atomizer core 20 is connected to the ventilation pipe 122 and is located in the second liquid storage chamber 102, wherein one end of the atomizer core 20 is connected to the ventilation pipe 122 through a first sealing ring, and the other end of the atomizer core 20 is connected to the inner wall surface of the second liquid storage tank 102 through a second sealing ring, thereby forming a liquid storage space with a storage function and preventing leakage at the connection.

[0048] The atomizing core 20 is provided with a liquid inlet hole connected to the second liquid storage tank 102, so as to supply liquid to the liquid storage cotton or porous matrix thereon, and the liquid storage cotton or porous matrix evenly conducts the aerosol matrix to the heating element, and the heating element atomizes the aerosol matrix to generate aerosol in the aerosol channel. Among them, the porous matrix can be porous glass or porous ceramics, etc.; the heating element can be a heating net or a heating film, etc.

[0049] See also Figure 2 , Figure 3 and Figure 6 The atomizer base 30 is connected to the other end of the tube shell 140 and the end of the first partition 142 away from the nozzle 12, wherein a sealing member 36 is provided between the atomizer base 30 and the inner wall surface of the tube shell 140 and the first partition 142 to weld and seal the connection position of the atomizer base 30 and the shell assembly 10 to form an integrated structure.

[0050] In other words, the atomizer base 30 is pre-installed on the atomizer shell 14, and then the atomizer base 30, the tube shell 140 and the first partition plate 142 are welded together to form an integrated structure through the sealing member 36, thereby eliminating the need for a complex connection structure and a sealing structure, eliminating the need for a sealing ring, saving sealing costs, and effectively reducing material costs. Compared with using a sealing ring to prevent leakage, the atomizer base 30 and the atomizer shell 14 are welded together to prevent leakage, and the anti-leakage performance of the structure is more reliable, and the uncontrollable risks caused by subsequent user disassembly can be avoided.

[0051] The atomizer base 30 and the atomizer shell 14 are welded into an integrated structure to prevent the first liquid storage tank 101 from leaking from the connection. A groove structure for welding is formed between the atomizer base 30 and the inner wall surface of the tube shell 140, and a groove structure for welding is also formed between the atomizer base 30 and the first partition 142. The groove structures at each location are filled with molten slurry of the sealing member 36. After the molten slurry solidifies, the atomizer base 30 and the atomizer shell 14 are welded into an integrated structure, so that the sealing effect is better and leakage is avoided.

[0052] In this embodiment, refer to Figure 2 and Figure 6 The atomizer base 30 includes a base 32 and a barrel 34 arranged on the base 32. The outer side surface of the base 32 is surrounded by a first welding groove 320. The side of the base 320 facing the first partition plate 142 is provided with a second welding groove 322 surrounding the barrel 34. The first welding groove 320 and the second welding groove 322 are connected; wherein the base 32 is embedded in the other end of the tube shell 140 away from the suction nozzle 12, the barrel 34 is inserted in the second liquid storage tank 102 and connected to the atomizer core 20, and the first partition plate 142 is inserted in the second welding groove 322 and a gap is left between the bottom of the second welding groove 322; the gap between the first welding groove 320 and the second welding groove 322 is filled with a sealing member 36.

[0053] The first welding groove 320 is connected to the second welding groove 322, and the first welding groove 320 is located on the outer side surface of the base 320 opposite to the inner wall surface of the tube shell 140 and exposed on the side of the base 32 away from the suction nozzle 12, so that the molten slurry is filled into the first welding groove 320, and the molten slurry can be filled in the first welding groove 320 and the second welding groove 322, so as to form a sealing member 36.

[0054] The cylinder 34 can guide the first partition 142, and the second welding groove 322 is also plugged into the first partition 142, which can play a positioning role and a connecting role. The first partition 142 also constitutes a cover for the second welding groove 322 to prevent the molten slurry from leaking into the first liquid storage tank 101 when forming the sealing member 36.

[0055] By providing a first welding groove 320 on the outer side surface of the base 32, and providing a second welding groove 322 on the end surface of the base 320 facing the first partition plate 142, and the first welding groove 320 and the second welding groove 322 are connected, after the atomizer base 32 and the atomizer shell 14 are pre-installed, the sealing component 36 is implanted in the mold of the sealing component 36 to be formed. Therefore, the filling can be filled into the second welding groove 322 through the first welding groove 320, so that the sealing component 36 can be efficiently formed, thereby achieving better sealing effect and higher efficiency.

[0056] Furthermore, a side of the base 32 away from the suction nozzle 12 is also provided with an anti-loosening groove 324 connected to the first welding groove 320, and the anti-loosening groove 324 is also filled with a sealing member 36, which further reinforces the welding effect of the sealing member 36 and the atomizing base 30 to be better and more stable.

[0057] The base 32 may be provided with one or two or more anti-loosening grooves 324 , which may further limit the position of the sealing member 36 to enhance the anti-loosening performance of the formed sealing member 36 , enhance its anti-disturbance capability, and prevent the sealing member 36 from loosening.

[0058] In this embodiment, Figure 2 As shown, the end of the atomizer core 20 facing the base 32 is connected to the cylinder 34 and sealed with the inner wall surface of the second liquid storage bin 102 ; a liquid absorbing member 37 is also installed in the cylinder 34 , and an air passage 370 is provided on the liquid absorbing member 37 which is offset from the atomization channel of the atomizer core 20 .

[0059] The base 32 is provided with an air inlet hole connected to the air duct 370. The air duct 370 is offset from the atomization channel of the atomization core 20, so that the condensed liquid formed in the atomization channel can directly fall to the liquid absorbing member 37 instead of falling to the air inlet hole to cause leakage.

[0060] The liquid absorbing member 37 can be liquid absorbing cotton or liquid absorbing paper, etc., which has strong liquid absorbing and storing capabilities and can prevent liquid from sliding from the air inlet to the host with a battery.

[0061] The base 32 is also provided with a liquid injection hole connected to the first liquid storage bin 101 and a liquid injection cap 326 for sealing the liquid injection hole. The liquid injection cap 326 is detachable to open the liquid injection hole and inject liquid into the first liquid storage bin 101, so that the atomizer 100 can be recycled.

[0063] The host 200 includes a shell 260, a battery holder 210, a battery 220 installed on the battery holder 210, a main board 230, an electrode 240 and an airflow sensor 250.

Figure 8 , Figure 8 1 is a flow chart of an embodiment of a method for manufacturing an atomizer provided by the present application, and the manufacturing method comprises:

[0069] Step 11: Provide the plastic part of the nozzle.

[0070] First, the suction nozzle 12 as described above is formed. The suction nozzle 12 can be a plastic part formed by compression molding or injection molding.

[0071] Step 12: Place the suction nozzle into a molding mold of the atomizer shell, and inject molten slurry into the molding mold to mold the atomizer shell, so as to weld the suction nozzle and the atomizer shell into one, and form a first liquid storage tank and a second liquid storage tank.

[0072] The suction nozzle 12 is placed in a molding mold of the atomizing shell 14, and then molten slurry is injected into the molding mold to mold the atomizing shell 14, so that the surface cover 120 of the suction nozzle 12 can be welded to the tube shell 140 of the atomizing shell 14, and the surface cover 120 of the suction nozzle 12 or the second partition 126 can be welded to the first partition 142 of the atomizing shell 14, wherein the second partition 126 can also be welded to the inner wall surface of the tube shell 140, so that the suction nozzle 12 and the atomizing shell 14 are combined into one without the need for an additional sealing structure, and a first liquid storage tank 101 and a second liquid storage tank 102 that are separated from each other are formed, and the first liquid storage tank 101 and the second liquid storage tank 102 are connected through the liquid hole 103 as mentioned above.

[0073] The suction nozzle 12 and the atomizing housing 14 are made of the same material, and thus can be welded together extremely well, so that the connection has a strong bonding ability and strength.

[0074] Step 13: Provide an assembled atomizer core and an atomizer base, and connect the atomizer base and the atomizer housing so that the atomizer core is located in the second liquid storage bin and is connected to the ventilation pipe of the nozzle.

[0075] The atomizer core 20 and the atomizer base 30 are pre-assembled together and then assembled together in the housing assembly 10, wherein the atomizer core 20 is located in the second liquid storage tank 102 and is connected to the vent pipe 122 of the nozzle 12, and the end of the atomizer core 20 relatively covers the second liquid storage tank 102, and the atomizer base 30 relatively covers the first liquid storage tank 101, so that the first liquid storage tank 101 and the second liquid storage tank 102 are connected only through the liquid hole 103.

[0076] Step 14: Inject molten slurry between the atomizer base and the atomizer shell to form a sealing member.

[0077] The preassembled shell assembly 10, atomizer core 20 and atomizer base 30 are implanted into a mold of a sealing member 36, and molten slurry is injected into the mold to form the sealing member 36, that is, molten slurry is injected into a first welding groove 320 between the atomizer base 30 and the tube shell 140 and a second welding groove 322 between the atomizer base 30 and the first partition plate 142, so that the atomizer base 30 and the atomizer shell 14 are welded into an integrated structure.

[0078] After the sealing parts are completed and demolded, the atomizer 100 can be manufactured. The process has high production efficiency, good product consistency, excellent anti-leakage effect, and can save sealing costs.

[0079] Different from the prior art, the present application discloses an electronic atomization device, an atomizer and a manufacturing method thereof. The surface cover of the suction nozzle is welded to one end of the tube shell of the atomizer shell, and the first partition of the atomizer shell is welded to the suction nozzle to separate the space in the tube shell into a first liquid storage tank and a second liquid storage tank. The welding sealing effect of the two is good, and there is no need to set up an additional sealing structure and sealing ring, which eliminates the risk of a large sealing failure caused by manual assembly, reduces material costs, and effectively improves the yield and production efficiency of the atomizer; the suction nozzle and the atomizer shell after welding form a first liquid storage tank and a second liquid storage tank separated from each other, and the side wall of the second liquid storage tank is provided with a liquid hole connected to the first liquid storage tank, and the atomizer core is provided with a liquid hole connected to the first liquid storage tank. The second liquid storage tank is connected to the ventilation pipe, so that the aerosol matrix in the first liquid storage tank can be isolated, which greatly reduces the risk of the aerosol in the first liquid storage tank being deteriorated due to the heating of the atomizer core. Only when the user tilts or inverts the atomizer to allow the aerosol in the first liquid storage tank to enter the second liquid storage tank to replenish the second liquid storage tank, the aerosol matrix that is not affected and has a good taste quality can be replenished into the second liquid storage tank, so that the taste of the aerosol generated by the atomizer core can be maintained at a high quality, the odor caused by the deteriorated aerosol is eliminated, and the quality of the atomizer can be further improved.
