It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0052] The electronic atomization device currently on the market includes an atomizer and a power supply host. The atomizer is used to store or store atomization medium. The power supply host provides electrical energy to the atomizer to atomize the atomization medium in the atomizer, thereby generating an aerosol. However, the atomizer is prone to leakage; and users find that the taste before and after inhaling the aerosol is significantly different, and the assembly process of the power supply host is relatively cumbersome, the working hours are too long, and the cost is increased.

[0053] Based on this, the embodiment of the present application provides an atomizer and a power supply host, wherein the atomizer reduces the risk of leakage; the assembly process of the power supply host is relatively simple, which shortens the working hours and reduces the cost.

[0054] The present application is described in detail below with reference to the accompanying drawings and embodiments.

[0055] See also Figure 1 to Figure 2 , Figure 1 A schematic diagram of the disassembly of an electronic atomization device provided in one embodiment of the present application; Figure 2 for Figure 1 The AA cross-sectional view of the electronic atomization device after assembly; Figure 3 for Figure 1 The BB section view of the assembled electronic atomization device is shown. In the present embodiment, an electronic atomization device is provided, which can be used in the fields of beauty, medical treatment, electronic cigarettes, etc. The electronic atomization device includes an atomizer 10 and a power supply host 20. The power supply host 20 is electrically connected to the atomizer 10, and is used to supply power to the atomizer 10. The atomizer 10 is used to atomize the atomization medium to form an aerosol when powered on. The atomization medium can be a liquid medicine formed by dispersing a certain medicine in a liquid solvent, an oil with added aroma components, or any other liquid suitable for atomization, such as e-liquid. For ease of introduction, the following embodiments of the present application take e-liquid as an example.

[0056] The specific structure and function of the atomizer are introduced in detail below.

[0057] Please read further Figures 4a to 7 , Figure 4a for Figure 1 A cross-sectional view taken along the line AA of the atomizer in the electronic atomization device shown; Figure 4b for Figure 1 A BB-section view of the atomizer in the electronic atomization device shown; Figure 5 for Figure 4a A schematic diagram of the structure of the atomizing assembly of the atomizer shown; Figure 6 for Figure 1 A schematic diagram of the disassembly of an atomizer assembly in the electronic atomizer device from a first perspective; Figure 7 for Figure 1 A schematic diagram of the disassembly of the atomizer assembly in the electronic atomizer device from a second perspective. The atomizer 10 includes an atomizer assembly 1 and a liquid storage assembly 2. The liquid storage assembly 2 has a liquid storage chamber 21, and the liquid storage chamber 21 is used to store or store an atomized medium. The atomizer assembly 1 includes an atomizer cup 11, a nozzle 12, a first injection molded part 13, a first sealing cover 14, an atomizer base 15, a vent pipe 16, an atomizer core 17 and an electrode assembly 18.

[0058] Among them, the atomizer cup 11 is a hollow structure with openings at both ends, and the port at the first end of the atomizer cup 11 forms the cup mouth of the atomizer cup 11. The suction nozzle 12 has a suction port 121, and the suction nozzle 12 is covered on the cup mouth of the atomizer cup 11, and cooperates with the atomizer cup 11 to form an atomization chamber 111. The atomizer cup 11 also has a first liquid inlet 112, and the liquid storage chamber 21 of the liquid storage assembly 2 is connected to the atomization chamber 111 through the first liquid inlet 112 to supply liquid to the atomization chamber 111. The first injection molded part 13 is injection molded at the connection and adjacent position of the atomizer cup 11 and the suction nozzle 12, so as to be sealed and fused with the atomizer cup 11 and the suction nozzle 12.

[0059] In the above scheme, the first injection molded part 13 is injection molded at the connection and adjacent positions of the atomizer cup 11 and the suction nozzle 12; that is, the atomizer cup 11 and the suction nozzle 12 are assembled and implanted into the mold of the first injection molded part 13, and the first injection molded part 13 is injected into the mold by molten plastic, so that the first injection molded part 13 is fused with the atomizer cup 11 and the suction nozzle 12. Therefore, the gap generated when the atomizer cup 11 and the suction nozzle 12 are assembled can be sealed by the first injection molded part 13 to prevent leakage of the atomized medium; on the one hand, when forming the atomizer During the process of assembling the atomizer cup 11 and the suction nozzle 12, it is not necessary to assemble and seal the atomizer cup 11 and the suction nozzle 12 with a silicone ring, because the silicone ring assembly seal is prone to wrinkles and misalignment, which may cause poor sealing. Therefore, the efficiency of the atomizer 10 formed by implanting the atomizer cup 11 and the suction nozzle 12 after injection molding is relatively high, thereby reducing production costs. On the other hand, the sealing effect at the connection between the atomizer cup 11 and the suction nozzle 12 is good, which can avoid the problem of leakage of the atomizer 10 caused by errors in assembling the atomizer cup 11 and the suction nozzle 12, thereby reducing the risk of leakage of the atomizer 10.

[0060] In one embodiment, in combination Figure 5, the atomizer cup 11 includes a first part and a second part along its depth direction Y; the first part is sealed and fused with the suction nozzle 12 through the first injection molded part 13, and the first liquid inlet 112 is specifically opened in the first part; and the width W of the cross section of the first part along the depth direction Y of the atomizer cup 11 is continuously reduced in a manner of gradually increasing at a decreasing rate along the direction away from the first liquid inlet 112. It can also be understood that the atomizer cup 11 is in the shape of a trumpet, and the first part is in the trumpet shape of the large mouth position. In this way, when the atomizing medium in the liquid storage chamber 21 is introduced into the atomizing chamber 111, it can not only buffer the flow rate of the atomizing medium entering the atomizing chamber 111 to reduce the risk of leakage, but also can divert the atomizing medium to the second part. The second part is in the trumpet shape of the small mouth position, that is, the trumpet shape of the atomizing medium flowing to the small mouth position, so that the amount of atomizing medium that can be stored in the small mouth position can cover the atomizing core 17 in time, and can provide the atomizing core 17 with smoke oil in time, so as to avoid the dry burning phenomenon caused by insufficient smoke oil during operation. At the same time, since the atomizer cup 11 is trumpet-shaped, the amount of atomizing medium that can be accommodated in the atomizing chamber 111 can be just used for the amount configured as the atomizing core 17 when it is working, so as to prevent the atomizing medium from leaking from the atomizing core 17. Therefore, in this solution, the capacity of the atomizing chamber 111 is 1-5ml, such as 1ml, 1.5ml, 1.8ml, 2.0ml, 2.5ml, 2.8ml, 3.0ml, 4.0ml, 5.0ml, etc.; preferably 1.8-2.8ml. The capacity of the liquid storage chamber 21 is 5-10 times that of the atomizing chamber 111. Therefore, when there is no atomizing medium in the atomizing chamber 111, the user can tilt the atomizer 10 so that the atomizing medium in the liquid storage chamber 21 is replenished into the atomizing chamber 111 for atomization of the atomizing core 17. When kept in use, the taste of the aerosol is consistent before and after, which improves the user experience.

[0061] The second part is directly connected to the first part, and the cross section of the second part along the depth direction Y of the atomizer cup 11 can be cylindrical to reduce the assembly gap between the atomizer cup 11 and the liquid storage assembly 2 and avoid shaking caused by unstable assembly. Of course, the cross section of the second part along the depth direction Y of the atomizer cup 11 can also be a trapezoid, a cone or other regular or irregular shapes.

[0062] The first sealing cover 14 is sleeved in the atomizing cup 11 from the second port of the atomizing cup 11 opposite to the cup mouth, and blocks the atomizing chamber 111. The atomizing base 15 is arranged on the side of the first sealing cover 14 facing the suction nozzle 12. The vent pipe 16 has a second liquid inlet 161, one end of the vent pipe 16 is arranged on the atomizing base 15, and part of the vent pipe 16 is clamped between the atomizing base 15 and the first sealing cover 14, so as to reduce the risk of the atomizing medium in the atomizing chamber 111 leaking through the connection between the vent pipe 16 and the atomizing base 15.

[0063] In some specific embodiments, the first sealing cover 14 is hollow and annular, and a first step portion is formed on the inner wall surface of the first sealing cover 14. The atomizing base 15 is carried on the first step portion and abuts against the side wall of the first step portion; and a second step portion is formed on the circumferential edge of the atomizing base 15, and the second step portion surrounds the circumference of the atomizing base 15. The side wall of the second step portion cooperates with the side wall of the first step portion to form a clamping groove. One end of the vent pipe 16 is embedded in the clamping groove to be clamped between the first sealing cover 14 and the atomizing base 15. In this way, the risk of leakage of the atomizing medium in the atomizing chamber 111 from the vent pipe 16 and the atomizing base 15 and / or the first sealing cover 14 can be reduced.

[0064] Of course, in other embodiments, the first sealing cover 14 and the atomizing base 15 may also be defined by other means to form a clamping groove to tightly clamp the ventilation tube 16 .

[0065] The other end of the vent pipe 16 is connected to the suction port 121. The atomizer core 17 is disposed in the vent pipe 16 corresponding to the second liquid inlet 161 of the vent pipe 16. The atomizer medium in the atomizer chamber 111 enters the atomizer core 17 through the second liquid inlet 161. The atomizer core 17 is configured to atomize the atomizer medium to form an aerosol. The aerosol flows out to the suction port 121 through the vent pipe 16 for the user to inhale.

[0066] In some embodiments, in combination Figure 5 In order to further improve the sealing performance of the atomizing chamber 111, the atomizer 10 further includes a third sealing cover 3, which is connected between the vent pipe 16 and the suction port 121 to seal the gap between the vent pipe 16 and the suction port 121 to prevent the atomizing medium in the atomizing chamber 111 from leaking through the gap.

[0067] Among them, the atomization core 17 includes an outer liquid guide part, an inner liquid guide part, a heating element and an atomization electrode. The outer liquid guide part is in contact with the inner wall surface of the ventilation tube 16; the inner liquid guide part is arranged on the side of the outer liquid guide part away from the ventilation tube 16. The outer liquid guide part and the inner liquid guide part are configured to guide the atomization medium entering from the second liquid inlet 161 to the outer liquid guide part and the inner liquid guide part in sequence, and the outer liquid guide part and the inner liquid guide part can be liquid guide cotton. The heating element is arranged on the side surface of the inner liquid guide part away from the outer liquid guide part, and is used to heat and atomize the atomization medium guided to its surface when power is turned on. The atomization electrode is electrically connected to the heating element, and is electrically connected to the electrode assembly 18 to supply power to the heating element.

[0068] The electrode assembly 18 includes an electrode support 181 and a first electrode 182 disposed on the electrode support 181. The electrode support 181 is at least partially embedded in the atomizer cup 11 and abuts against the side of the first sealing cover 14 away from the suction nozzle 12, and the rest of the electrode support 181 is exposed from the atomizer cup 11. A plug hole 141 is abutted against the side of the first sealing cover 14 away from the suction nozzle 12, and the first electrode 182 is inserted into the plug hole 141 to achieve a stable electrical connection with the atomizer core 17.

[0069] In some embodiments, the atomizer 10 further includes a second injection molded part 4 , which is injection molded at least on the outer periphery of the electrode holder 181 and is sealed and connected to the atomizer cup 11 and the electrode holder 181 . In this way, the atomizer cup 11, the atomizer core 17, the first sealing cover 14 and the electrode bracket 181 are assembled and implanted into the mold of the second injection molded part 4, and the molten plastic slurry is injected into the mold to form the second injection molded part 4. Therefore, the second injection molded part 4 is sealed and fused with the atomizer cup 11, the first sealing cover 14 and the electrode bracket 181 to form an integrated atomizer component 1 structure, which reduces the assembly process, not only improves the production efficiency of the atomizer 10, but also ensures the consistency of the atomizer 10; and the connecting gap between the atomizer cup 11 and the first sealing cover 14 and the electrode bracket 181 is sealed by the second injection molded part 4, and the sealing effect is good, avoiding the risk of leakage of the atomized medium in the atomization chamber 111 through the gap between the atomizer cup 11 and the first sealing cover 14 and the electrode bracket 181, thereby improving the stability of the atomizer 10 during use and enhancing the user experience.

[0070] The outer periphery of the electrode support 181 refers to the outer wall surface of the side wall of the electrode support 181. In some embodiments, the second injection molded part 4 is injection molded on at least one circle of the electrode support 181 along the circumferential direction thereof.

[0071] It should be noted that the injection molding involved in this application refers to in-mold injection molding, which means placing an already molded component into another mold and injection molding it with another plastic material. Therefore, the two components are connected together without the need for manual assembly, and the connection is firm, which improves production efficiency and reduces costs.

[0072] In some embodiments, in combination Figures 4a to 6The cup wall of the atomizer cup 11 has at least one notch 113. Specifically, the number of the notches 113 can be multiple, and the multiple notches 113 are arranged at equal intervals along the circumferential direction of the atomizer cup 11. Each notch 113 extends from an end of the atomizer cup 11 away from the cup opening toward the cup opening, and the notch 113 exposes a portion of the electrode bracket 181 and a portion of the first sealing cover 14 along its circumferential direction. In this embodiment, the second injection molded part 4 is further molded by in-mold injection on the outer side of the portion of the first sealing cover 14 exposed through the notch 113 and the outer side of the portion of the electrode bracket 181 exposed through the notch 113, so that the atomizer cup 11, the electrode bracket 181 and the first sealing cover 14 are seamlessly connected and integrated through the second injection molded part 4, that is, the second injection molded part 4 is sealed and connected to the atomizer cup 11, the electrode bracket 181 and the first sealing cover 14, so as to prevent the atomized medium in the atomization chamber 111 from leaking from the gap between the first sealing cover 14 and the atomizer cup 11 or the electrode bracket 181 and the atomizer cup 11. Furthermore, the second injection molded part 4 can further enhance the connection stability between the atomizer cup 11, the electrode bracket 181 and the first sealing cover 14, thereby making the electrical connection between the first electrode 182 and the atomizer core 17 more stable.

[0073] In some embodiments, in combination Figure 5 A liquid absorbing cotton 19 is also provided between the electrode bracket 181 and the atomizing base 15 to absorb condensed liquid or the outflowing atomizing medium to avoid leakage outside the atomizing assembly 1.

[0074] In some embodiments, in combination Figure 6 , two plug holes 141 are provided on the surface of the side of the first sealing cover 14 away from the ventilation pipe 16; the two plug holes 141 are arranged on both sides of the center position of the first sealing cover 14. The atomizing electrode includes a positive atomizing electrode and a negative atomizing electrode, the positive atomizing electrode and the negative atomizing electrode respectively pass through the first sealing cover 14 and extend from the side of the first sealing cover 14 away from the ventilation pipe 16 to the two plug holes 141; wherein, one plug hole 141 corresponds to one atomizing electrode. The first electrode 182 includes a positive electrode and a negative electrode, the positive electrode and the negative electrode are respectively inserted into the two plug holes 141 of the first sealing cover 14, and are in contact and electrically connected with the corresponding atomizing electrode extending into the plug hole 141.

[0075] In the above solution, when the first electrode 182 is inserted into the plug hole 141, the first electrode 182 can further contact and electrically connect with the atomizing electrode. At the same time, this solution extends the atomizing electrode into the plug hole 141. Compared with the solution in which the atomizing electrode extends vertically downward perpendicular to the atomizing base 15, it can prevent the atomizing electrode from abutting against the electrode support 181 during the assembly of the electrode assembly 18 and the first sealing cover 14, resulting in the first sealing cover 14 and the electrode support 181 not being able to fit tightly; or the atomizing electrode being broken or the electrode support 181 being damaged due to pressure.

[0076] The atomizing electrode may extend to the side wall and / or bottom wall of the plug hole 141. Preferably, the atomizing electrode may extend further to the bottom wall of the plug hole 141 through the side wall of the plug hole 141, so that after the electrode holder 181 and the first sealing cover 14 are assembled, the electrode holder 181 is sealed and fused to the atomizing cup 11 through the second injection molded part 4, and the position of the electrode holder 181 is fixed, so that the effective electrical connection between the first electrode 182 and the atomizing electrode can be ensured. It can be understood that here, the first electrode 182 and the plug hole 141 can also play a certain foolproof role.

[0077] In some embodiments, the first electrode 182 and the electrode holder 181 can be integrally formed by injection molding. It can also be understood that the first electrode 182 is implanted in a mold of the electrode holder 181, and molten plastic slurry is injected into the mold to form the electrode holder 181, so that the relative position of the first electrode 182 and the electrode holder 181 can be ensured, and the connection is stable. In this way, the production efficiency of the atomizer 10 can be improved, and the electrode stability of the first electrode 182 can be improved.

[0078] In some embodiments, see Figures 8 to 11 , Figure 8 for Figure 1 The overall structural schematic diagram of the liquid storage assembly in the electronic atomization device shown; Fig. 9 for Figure 8 A disassembled schematic diagram of the liquid storage assembly shown; Fig.10 for Figure 8 A CC sectional view of the liquid storage assembly shown; Fig.11 for Figure 8DD section view of the liquid storage assembly shown. The liquid storage assembly 2 includes a third injection molded part 22, a first base 23 and a liquid storage shell 24, and the first base 23 and the liquid storage shell 24 cooperate to form a liquid storage cavity 21. In one embodiment, the first base 23 is embedded in the liquid storage shell 24 and is located at one end of the liquid storage shell 24. The third injection molded part 22 is injection molded at the connection between the first base 23 and the liquid storage shell 24 and at an adjacent position to achieve a sealed connection between the first base 23 and the liquid storage shell 24. In this way, the liquid storage cavity 21 can be sealed by the third injection molded part 22 to prevent the atomized medium in the liquid storage cavity 21 from leaking at the connection between the first base 23 and the liquid storage shell 24. Specifically, the first base 23 and the liquid storage shell 24 are implanted into the mold of the third injection molded part 22, and the molten plastic slurry is injected into the mold to form the third injection molded part 22. Therefore, the third injection molded part 22 is injection molded on the side surface of the first base 23 away from the suction nozzle 12 and the inner surface of the liquid storage shell 24, so that the third injection molded part 22 is fused with the first base 23 and the liquid storage shell 24 to form an integral molding, so as to achieve a sealed connection between the first base 23 and the liquid storage shell 24, and prevent the liquid storage component 2 from leaking the atomized medium due to changes in temperature and pressure during transportation on land or in the air. Among them, the side surface of the third injection molded part 22 away from the first base 23 is flush with the end surface of the liquid storage shell 24 away from the suction nozzle 12, so that the connection between the first base 23 and the liquid storage shell 24 is sealed by the third injection molded part 22 without increasing the length of the liquid storage component 2 along its axial direction Y, and the consistency of the appearance of the liquid storage component 2 can be ensured.

[0079] Combination Figure 4a and Figure 8 The liquid storage assembly 2 is annular and surrounds a receiving cavity 25; the end of the atomizer cup 11 away from the suction nozzle 12, that is, the second part of the atomizer cup 11 is sleeved in the receiving cavity 25. Such a design can not only make the volume of the atomizer 10 smaller, but also make the visual effect produced by partially hiding the atomizer cup 11 in the liquid storage assembly 2 more beautiful; at the same time, it can also make it more convenient to disassemble and separate the atomizer cup 11 and the liquid storage assembly 2.

[0080] In a specific embodiment, in combination Figure 8 , the nozzle 12, the atomizer cup 11 and the liquid storage assembly 2 are coaxially arranged, and the orthographic projections of the atomizer cup 11 and the nozzle 12 on the plane where the liquid storage assembly 2 is located fall within the liquid storage assembly 2; in this way, the volume of the atomizer 10 can be further reduced. Among them, the liquid storage assembly 2 has an air inlet groove 243 at one end facing the nozzle 12; there is an assembly gap after the atomizer cup 11 and the second injection molded part 4 are assembled with the liquid storage shell 24, and the external gas can enter the atomizer core 17 through the air inlet groove 243, the assembly gap between the atomizer cup 11 and the second injection molded part 4 and the liquid storage shell 24 in sequence.

[0081] Specifically, the first base 23 is hollow and annular, and the liquid storage housing 24 includes an inner side wall, an outer side wall, and a top wall connecting the inner side wall and the outer side wall. Among them, the inner side wall and the outer side wall are both closed-loop, and the end of the inner side wall away from the top wall is connected to the inner side of the first base 23. The outer side wall is sleeved on the periphery of the inner side wall, and is arranged on the outer side of the first base 23, and is spaced from the inner side wall, and cooperates with the top wall, the inner side wall and the first base 23 to form a liquid storage cavity 21, and the liquid storage cavity 21 is used to store or store atomized medium. The cavity formed by the side of the inner side wall away from the outer side wall is the accommodating cavity 25.

[0082] Combination Fig.10 The inner wall surface of the accommodating cavity 25 has a guide groove 26, and the guide groove 26 extends from the end of the liquid storage component 2 close to the suction nozzle 12 toward the end away from the suction nozzle 12. Figure 6 or Figure 7 The outer wall surface of the second injection molded part 4 has a guide protrusion 41, which is embedded in the guide groove 26 and can slide back and forth along the extension direction of the guide groove 26. In this way, during the assembly of the atomizer assembly 1 and the liquid storage assembly 2, the assembly process of the two can be guided by the cooperation of the guide protrusion 41 and the guide groove 26 to ensure that the drainage column 241 of the liquid storage assembly 2 is accurately inserted into the first liquid inlet 112.

[0083] In some embodiments, in combination Figure 4b and Fig.10 The bottom wall of the guide groove 26 also has a clamping groove 27; the clamping groove 27 extends toward the outside of the liquid storage assembly 2. The outer wall surface of the atomizer cup 11 has a clamping protrusion 114; the clamping protrusion 114 is embedded in the clamping groove 27 to fix the relative position of the atomizer cup 11 and the liquid storage assembly 2 to prevent the liquid storage assembly 2 from falling off the atomizer assembly 1.

[0084] In some embodiments, in combination Fig. 9 , a drainage column 241 is provided at one end of the liquid storage housing 24 away from the first base 23, that is, a drainage column 241 is provided on the top wall of the liquid storage housing 24; the drainage column 241 has a liquid outlet connected to the liquid storage chamber 21. A first liquid inlet 112 is provided at a position of the atomizing cup 11 corresponding to the drainage column 241; the drainage column 241 is inserted into the first liquid inlet 112 and connected to the atomizing chamber 111. The atomizing medium in the liquid storage chamber 21 can enter the atomizing chamber 111 through the liquid outlet, and then enter the atomizing core 17 through the second liquid inlet 161 on the vent pipe 16 for atomization.

[0085] In other embodiments, when there is no atomizing medium in the atomizing chamber 111 or the atomizing medium becomes less, the user can tilt the atomizer 10 to allow the atomizing medium in the liquid storage chamber 21 to enter the atomizing chamber 111 through the liquid outlet to replenish the atomizing medium in the atomizing chamber 111. When the atomizing medium in the atomizing chamber 111 is relatively large or full, the user can use the atomizer 10 to inhale the aerosol normally. Therefore, the user does not need to unscrew the atomizing assembly 1 to add the atomizing medium to the atomizing chamber 111, which is convenient and efficient, and can avoid the influence of the atomizing core 17 on the deterioration of the atomizing medium in the liquid storage chamber 21 when working, thereby improving the user experience.

[0086] In some embodiments, the volume of the liquid storage chamber 21 is larger than that of the atomizing chamber 111, that is, the capacity of the liquid storage chamber 21 that can accommodate the atomizing medium is larger than that of the atomizing chamber 111. In a specific embodiment, the capacity of the liquid storage chamber 21 is 5-10 times that of the atomizing chamber 111. Under the condition that the atomizing medium capacity is sufficiently provided, the aerosol produced by the user using the atomizer 10 is ensured to have a constant taste and is conveniently supplied to the atomizing chamber 111, thereby improving the user experience.

[0087] Among them, combined Figure 8-Figure 11 The atomizer 10 further includes a second sealing cover 28, which is sleeved on the outside of the drainage column 241 and located between the drainage column 241 and the first liquid inlet 112, so that the drainage column 241 is sealed and connected to the atomizing cup 11. In this way, the risk of leakage of the atomized medium at the connection between the drainage column 241 and the first liquid inlet 112 can be reduced. In this embodiment, the second sealing cover 28 is made of silicone material, and can also be made of elastic materials such as silicone rubber.

[0088] Combination Figure 4a and Fig.10 The liquid storage component 2 further includes a sealing plug 29, which is movably connected to the liquid outlet along the depth direction Y of the liquid storage component 2, so as to be configured to a first position to expose the liquid outlet; or configured to a second position to block the liquid outlet. The sealing plug 29 can be configured from the first position to the second position, or from the second position to the first position under the action of gravity. In some embodiments, Figure 2 Taking the orientation shown as an example, when the suction nozzle 12 is vertically downward, the sealing plug 29 can move toward the suction nozzle 12 under the action of its own gravity, so as to be configured from the second position to the first position, so as to expose at least part of the liquid outlet, so that the atomized medium in the liquid storage chamber 21 can flow out from the liquid outlet. When the suction nozzle 12 is vertically upward, the sealing plug 29 can be moved back to the liquid inlet under the action of its own gravity, so as to be configured from the first position to the second position, so as to block the liquid storage chamber 21 and prevent the atomized medium from flowing out.

[0089] In the process of the sealing plug 29 being configured back and forth between the first position and the second position, part of the sealing plug 29 is always sleeved in the liquid outlet, so that the side wall of the drainage column 241 can guide and limit the moving path of the sealing plug 29 to prevent the sealing plug 29 from being unable to accurately return to the second position after being separated from the liquid outlet. In this embodiment, the cross-sectional area of ​​the end of the sealing plug 29 facing the first base 23 can be smaller than the cross-sectional area of ​​the liquid outlet, so that after the sealing plug 29 moves to the first position, the atomized medium in the liquid storage chamber 21 can flow out from the gap between the sealing plug 29 and the inner wall surface of the liquid outlet.

[0090] In other embodiments, the liquid storage component 2 further includes a sealing plug 29, which is disposed in the liquid outlet of the drainage column 241 and sealed at the liquid outlet. When the liquid storage component 2 is not connected to the atomizing component 1, the atomized medium in the liquid storage component 2 is sealed by the sealing plug 29 to prevent leakage, so the liquid storage component 2 is packaged separately for storage and convenient to carry; when the liquid storage component 2 is connected to the atomizing component 1, the sealing plug 29 is first unplugged, and then assembled with the atomizing component 1, so the user only needs to tilt the atomizer 10 to realize that the atomized medium in the liquid storage component 2 is replenished into the atomizing chamber 111 through the drainage column 241, and there is no need to manually inject the atomized medium into the atomizing chamber 111, so as to improve the convenience of use.

[0091] In some embodiments, see Fig.11 A dam 242 is disposed around the drainage column 241, and the dam 242 is spaced apart from the drainage column 241 to define a liquid storage tank. In this way, the atomized medium flowing out of the liquid outlet or the first liquid inlet 112 can be stored in the liquid storage tank to reduce the risk of the leaked atomized medium flowing in all directions and contaminating the atomizer 10. The surface of the side of the dam 242 facing the atomization cup 11 matches the contour of the corresponding position of the atomization cup 11 to ensure that the two fit closely.

[0092] The atomizer 10 provided in the embodiment of the present application includes an atomizer cup 11, a nozzle 12, a first injection molded part 13 and an atomizer core 17; wherein the atomizer cup 11 has a cup mouth; the nozzle 12 has a suction port 121, and is covered on the cup mouth of the atomizer cup 11, and cooperates with the atomizer cup 11 to form an atomizer cavity 111; the atomizer core 17 is arranged in the atomizer cavity 111, and is configured to atomize the atomization medium in the atomizer cavity 111 to form an aerosol; the first injection molded part 13 is formed by in-mold injection at the connection and adjacent position of the atomizer cup 11 and the nozzle 12, so as to be sealed and fused with the atomizer cup 11 and the nozzle 12 as a whole. On the one hand, in the process of forming the atomizer 10, there is no need to seal and assemble the atomizer cup 11 and the suction nozzle 12, and the corresponding components can be formed by in-mold injection molding, so the efficiency of forming the atomizer 10 is high; on the other hand, the sealing effect at the connection between the atomizer cup 11 and the suction nozzle 12 is good, which can avoid the problem of leakage of the atomizer 10 caused by the error caused by assembling the atomizer cup 11 and the suction nozzle 12, that is, the sealing consistency effect is better.

[0093] The specific structure and function of the power supply host 20 are introduced below.

[0094] See also Figures 12 to 15 , Fig.12 for Figure 1 The overall structural diagram of the power supply host in the electronic atomization device shown; Fig.13 for Fig.12 Schematic diagram of disassembly of the power supply host; Fig.14 for Fig.12 EE section view of the power supply host; Fig.15 for Fig.12FF sectional view of the power supply host. The power supply host 20 includes a power supply base 5, a power supply shell 6, a power supply assembly 7, a power supply electrode 8 and a power supply injection molded part 9. The power supply shell 6 cooperates with the power supply base 5 to form a receiving cavity. The power supply assembly 7 is arranged in the receiving cavity. The power supply electrode 8 is electrically connected to the power supply assembly 7, and the power supply electrode 8 at least partially protrudes from the power supply shell 6; the power supply electrode 8 is configured to be electrically connected to the first electrode 182 of the atomizer 10. The power supply injection molded part 9 is molded at the connection between the power supply base 5 and the power supply shell 6 by in-mold injection molding, so that the connection between the power supply base 5 and the power supply shell 6 is sealed and connected by the power supply injection molded part 9. It can also be understood that the power supply injection molded part 9 is fused with the power supply base 5 and the power supply shell 6 respectively during the injection molding process in the mold, so that the power supply injection molded part 9 is seamlessly connected with the power supply base 5 and the power supply shell 6, that is, the power supply injection molded part 9, the power supply base 5 and the power supply shell 6 are formed as a whole in the mold. In this way, the power supply host 20 can be formed into a whole, the power supply component 7 cannot be removed from the power supply shell 6, the battery 72 can be used more safely and reliably, and the sealing effect of the power supply host 20 can be improved to prevent air leakage from affecting the power supply start-up function. At the same time, since the power supply injection molded part 9 is integrally molded with the power supply base 5 and the power supply shell 6 by mold injection molding, the efficiency is high and the cost is reduced.

[0095] In some embodiments, the power supply base 5 is sleeved in the power supply housing 6 and is located at one end of the power supply housing 6. The outer wall of the power supply base 5 is formed with an annular groove along its circumferential direction; the power supply injection molded part 9 is injection molded in the annular groove; in this way, not only can the power supply base 5 and the power supply housing 6 be sealed and connected through the power supply injection molded part 9, but the power supply injection molded part 9 is not exposed from the side wall of the power supply housing 6, and the appearance consistency of the power supply electrode 8 is better; and the flatness of the bottom of the power supply host 20 can be ensured.

[0096] In some embodiments, in combination Fig.14 The power supply housing 6 includes a first housing portion 61 and a second housing portion 62; the first housing portion 61 has a first cavity 611, and the power supply assembly 7 is disposed in the first cavity 611; the second housing portion 62 is located on the side of the first housing portion 61 away from the power supply base 5, and the power supply electrode 8 protrudes from the end of the second housing portion 62 away from the first housing portion 61. The second housing portion 62 is configured to be inserted into the accommodating cavity 25 of the liquid storage assembly 2 of the atomizer 10, so that the power supply electrode 8 abuts against the first electrode 182 of the atomizer 10. This connection method can reduce the volume of the power supply host 20 after being connected to the atomizer 10.

[0097] In some embodiments, in combination Fig.14, the second housing portion 62 has a second cavity 621; the second cavity 621 is coaxially arranged with the first cavity 611 and is interconnected; the power supply electrode 8 specifically passes through the second cavity 621 and protrudes from the second housing portion 62. Among them, the side walls of the first housing portion 61 and the second housing portion 62 are of equal thickness. The cross-sectional area of ​​the second cavity 621 is smaller than the cross-sectional area of ​​the first cavity 611; that is, the cross-sectional area of ​​the second housing portion 62 is also smaller than the cross-sectional area of ​​the first housing portion 61; in this way, on the one hand, the second housing portion 62 can be smoothly inserted into the accommodating cavity 25 of the atomizer 10; on the other hand, the atomizer 10 can be supported by the first housing portion 61 to ensure the consistency of the outer diameter of the atomizer 10 and the outer diameter of the power supply host 20, thereby improving the overall coordination. In other embodiments, the atomizer 10 is detachably connected to the power supply host 20, and the user can disassemble the atomizer 10 by applying force through the first housing portion 61, and the power supply host 20 can be reused to reduce the use cost.

[0098] In this embodiment, combined with Fig.14 The power supply host 20 further includes a power supply sealing cover 30, which covers the second cavity 621 and is clamped between the second circuit board 73 and the end wall of the first cavity 611 away from the power supply base 5. In this way, the port of the second cavity 621 facing the first cavity 611 can be sealed by the power supply sealing cover 30, so that the atomized medium or condensed liquid leaked into the power supply host 20 can be stored by the second cavity 621, and the risk of further leakage of the atomized medium or condensed liquid into the first cavity 611, damaging the battery 72, or leaking from the first cavity 611 can be reduced, thereby improving the safety of use and enhancing the user experience.

[0099] Among them, the sealing covers involved in the present application can all be structures made of elastic materials such as plastic, rubber, or silicone to play a certain sealing role.

[0100] In some embodiments, see Fig.13 , the power supply assembly 7 includes a first circuit board 71, a battery 72 and a second circuit board 73. The first circuit board 71 is arranged on the power supply base 5. The battery 72 is arranged on the first circuit board 71, and is in contact and electrically connected with the first circuit board 71. The second circuit board 73 is arranged at one end of the battery 72 away from the first circuit board 71, and is in contact and electrically connected with the battery 72; wherein the power supply electrode 8 is electrically connected to the second circuit board 73. In this solution, the battery 72 and the first circuit board 71 and the second circuit board 73 are electrically connected to each other by direct abutment, and welding is not required. The connection stability between the battery 72 and the two circuit boards is good, and labor hours are saved. Among them, the first circuit board 71 and the second circuit board 73 can be PCB boards. The battery 72 can be a dry cell 72, a lead-acid battery 72 or a lithium battery 72, etc.

[0101] In some embodiments, see Fig.13 and Fig.14 The power supply electrode 8 includes a first connection electrode 81 and a second connection electrode 82; the first connection electrode 81 is in contact and electrically connected with the second circuit board 73 of the power supply assembly 7. The second connection electrode 82 is injection molded on the power supply housing 6 and is electrically connected to the first connection electrode 81 in abutment, and the second connection electrode 82 at least partially protrudes from the power supply housing 6 and is configured to be electrically connected to the first electrode 182. In this embodiment, the first connection electrode 81 and the second connection electrode 82 are elastically abutted, so that the electrical connection is more stable.

[0102] In a specific embodiment, the first housing portion 61 and the second housing portion 62 are integrally formed by injection molding, and the second connection electrode 82 is specifically injection molded on the inner wall surface of the second housing portion 62 and is located in the second cavity 621. In this way, there is no need to assemble the first housing portion 61, the second housing portion 62 and the second connection electrode 82. It is only necessary to implant the second connection electrode 82 into the mold and integrally form it with the first housing portion 61 and the second housing portion 62, and the finished product can be obtained by one-time demolding. Therefore, the process of forming the power supply host 20 is relatively simple, the working hours are short, the cost is low, and the product has good consistency and better stability, avoiding the phenomenon of poor electrical contact caused by assembly tolerance during the assembly process, thereby improving user experience.

[0103] In some embodiments, please refer to Fig.14 , an end of the second shell portion 62 away from the power supply base 5 is also provided with an airflow hole 622 connected to the second cavity 621. The power supply host 20 also includes an airflow sensor 40, which is electrically connected to a side surface of the second circuit board 73 away from the power supply base 5, and is electrically connected to the first circuit board 71 through the second circuit board 73. Specifically, the second circuit board 73 and the first circuit board 71 are electrically connected through a wire 74. The airflow sensor 40 is configured to sense airflow changes through the airflow hole 622 to control the opening or closing of the power supply host 20.

[0104] In the above scheme, since the second cavity 621 is sealed by the power supply sealing cover 30, the airflow sensor 40 is arranged in the second cavity 621, so that the triggering of the airflow hole 622 is more stable, and the risk of insensitive triggering due to assembly error of the power supply host 20 is reduced.

[0105] In this embodiment, the power supply sealing cover 30 has a convex column 31 at the position corresponding to the airflow sensor 40, and the height of the convex column 31 is higher than the height of the airflow sensor 40; the convex column 31 has a through hole, and the airflow sensor 40 is exposed to the second cavity 621 through the through hole of the convex column 31. In this way, the power supply sealing cover 30 will not hinder the connection between the airflow sensor 40 and the airflow hole 622, and the convex column 31 can reduce the risk of the atomized medium or condensate in the second cavity 621 contacting with the airflow sensor 40 and damaging the airflow sensor 40, and can also reduce the risk of the atomized medium or condensate in the second cavity 621 leaking to the surface of the power supply assembly 7 or the outside of the power supply housing 6 through the gap between the power supply sealing cover 30 and the airflow sensor 40.

[0106] In a specific embodiment, in combination Fig.12 One end of the second shell portion 62 that abuts against the atomizer 10 also has an air passage groove 623 , and external air enters the air flow hole 622 through the air passage groove 623 and then enters the atomizer 10 .

[0107] In some embodiments, the end surface of the second housing portion 62 facing away from the first housing portion 61 is further provided with a first magnetic member 63, and the electrode bracket 181 is provided with a second magnetic member at a position corresponding to the first magnetic member 63, and the atomizer 10 and the power supply host 20 are connected by the magnetic adsorption force of the first magnetic member 63 and the second magnetic member. Among them, one of the first magnetic member 63 and the second magnetic member can be a magnet, and the other can be a ferromagnetic material. Or both the first magnetic member 63 and the second magnetic member can be magnets.

[0108] The power supply host 20 provided in this embodiment includes a power supply base 5, a power supply shell 6, a power supply component 7, a power supply electrode 8 and a power supply injection molded part 9; wherein the power supply shell 6 cooperates with the power supply base 5 to form a receiving cavity; the power supply component 7 is arranged in the receiving cavity; the power supply electrode 8 is electrically connected to the power supply component 7, the power supply electrode 8 at least partially protrudes from the power supply shell 6, and is configured to be electrically connected to the atomizer 10; the power supply injection molded part 9 is injection molded at the connection and adjacent positions of the power supply base 5 and the power supply shell 6, that is, the power supply injection molded part 9 is injection molded and welded to the connection and adjacent positions of the power supply base 5 and the power supply shell 6, so that the power supply injection molded part 9, the power supply base 5 and the power supply shell 6 are integrally formed. It can also be understood that the power supply base 5, the power supply assembly 7 and the power supply shell 6 are implanted into the mold of the power supply injection molding 9, and then the power supply base 5 and the power supply shell 6 are fused together by molding the power supply injection molding 9, so that the three form an inseparable whole with better sealing, so that the power supply base 5 and the power supply shell 6 are sealed and connected, so that the power supply host 20 forms a whole, the power supply assembly 7 cannot be removed from the power supply shell 6, and the battery 72 is safer and more reliable to use. In addition, since the power supply base 5 and the power supply shell 6 are fused together by molding the power supply injection molding 9, the power supply assembly 7 is fixed in the power supply shell 6 and is not easy to loosen, so that the battery 72 and the first circuit board 71 and the second circuit board 73 are electrically connected to each other by direct abutment, without the need for welding, the connection stability between the battery 72 and the two circuit boards is better, and labor hours are saved. In addition, the first housing portion 61 and the second housing portion 62 are integrally formed by injection molding, and the second connection electrode 82 is implanted in the mold of the first housing portion 61 and the second housing portion 62 and is integrally formed therewith; specifically, the second connection electrode 82 is injection molded on the inner wall surface of the second housing portion 62 and is located in the second cavity 621. In this way, there is no need to assemble the first housing portion 61, the second housing portion 62 and the second connection electrode 82, and the process of forming the power supply host 20 is relatively simple, the working hours are short, and the cost is low.

The difference between the electronic atomization device and the electronic atomization device provided in the above embodiment is that the first circuit board 71 of the power supply host 20 is located in the first cavity 611, and abuts against the end wall of the first cavity 611 at one end close to the second cavity 621; the battery 72 and the second circuit board 73 are both located in the second cavity 621. In this way, part of the power supply assembly 7 can also be accommodated in the atomizer 10; this can not only reduce the overall length of the electronic atomization device along its axial direction Y, but also extend the length of the liquid storage chamber 21 of the atomizer 10 along the axial direction Y of the electronic atomization device, thereby increasing the volume of the liquid storage chamber 21 to extend the service life of the atomizer 10. In addition, from the appearance of the electronic atomization device, the shell of the atomizer 10 occupies most of the proportion of the electronic atomization device along its axial direction Y. In this embodiment, the shell of the atomizer 10, that is, the liquid storage shell 24, is a transparent shell, which enhances the visual effect of the electronic atomization device and at the same time can make the product consistency better.

[0110] In this embodiment, the power supply sealing cover 30 is clamped between the second circuit board 73 and the end wall of the second cavity 621 away from the first cavity 611. The positive projection of the airflow hole 622 on the power supply sealing cover 30 falls within the through hole of the protruding column 31, so that the airflow sensor 40 can sense more sensitively.

[0111] In some embodiments, the accommodating chamber 25 of the atomizer 10 includes a first chamber 251 and a second chamber 252; a portion of the atomizer assembly 1 is inserted into the first chamber 251 from one end of the first chamber 611 away from the second chamber 252 and extends into the second chamber 252. The second chamber 252 is coaxially arranged with the first chamber 251, and the cross-sectional area of ​​the second chamber 252 is greater than the cross-sectional area of ​​the first chamber 251. The second housing portion 62 of the power supply host 20 is specifically configured to be inserted into the second chamber 252 of the atomizer 10.

[0112] In some embodiments, the second housing portion 62 further has a sleeve portion 624 at one end away from the first housing portion 61, and the second housing portion 62 is sleeved on the periphery of the second injection molded part 4 extending to the second cavity 252 through the sleeve portion 624, and the sleeve portion 624 has an avoidance groove 625 at a position corresponding to the guide protrusion 41 to ensure that the guide protrusion 41 can slide freely in the guide groove 26. At the same time, it can also prevent the power supply host 20 from rotating and thus causing poor electrical contact.

[0113] It can be understood that in this embodiment, the length of the second cavity 252 along the axial direction Y of the liquid storage component 2 is at least not less than the sum of the length of the battery 72 and the thickness of the second circuit board 73 and the thickness of the power supply sealing cover 30. However, in the electronic atomization device provided in the first embodiment, the length of its accommodating cavity 25 is not limited by the length of the power supply component 7. Therefore, in order to reduce the length of the product, the length of the liquid storage component 2 of the electronic atomization device provided in the first embodiment along its axial direction Y can be less than the length of the liquid storage component 2 in the electronic atomization device provided in the second embodiment along its axial direction Y. In addition, after the power supply host 20 and the atomizer 10 are assembled, in order to make the battery 72 also located in the atomizer 10 and not increase the cross-sectional area of ​​the atomizer 10 provided in the first embodiment, the cross-sectional area of ​​the second cavity 252 of the atomizer 10 provided in the second embodiment is greater than the cross-sectional area of ​​the portion of the accommodating cavity 25 of the atomizer 10 provided in the first embodiment for accommodating the second shell portion 62.

[0114] For other specific structures and functions of the power supply host 20 and the atomizer 10 involved in this embodiment, reference may be made to the relevant descriptions involved in the above embodiments.

[0115] In one embodiment, a method for forming an electronic atomization device is further provided. The method can be used to form the electronic atomization device involved in any of the above embodiments. The forming method includes:

[0116] Step S1: Cover the mouth of the atomizer cup 11 with the suction nozzle 12, and implant the suction nozzle 12 and the atomizer cup 11 into a mold of a first injection molded part 13 to injection mold the first injection molded part 13, so that the suction nozzle 12 and the atomizer cup 11 are sealed and fused into one piece through the first injection molded part 13.

[0120] In some embodiments, before step S2, the electrode holder 181 and the first electrode 182 are also formed into one piece by injection molding to eliminate the process of assembling the electrode holder 181 and the first electrode 182, thereby saving labor hours, reducing costs, accelerating the molding rate, improving production efficiency, and achieving good product consistency.

[0121] Step S3: Assemble the first base 23 and the liquid storage shell 24 and implant them into the mold of the third injection molded part 22 to form the third injection molded part 22, that is, the third injection molded part 22 is formed by injection molding at the connection and adjacent positions of the first base 23 and the liquid storage shell 24, so as to form the first base 23 and the liquid storage shell 24 sealed and fused together through the third injection molded part 22.

[0122] Specifically, the first base 23 is embedded in the end of one end of the liquid storage shell 24, and the first base 23 can be riveted to the end of the liquid storage shell 24 by riveting, and then the first base 23 and the liquid storage shell 24 are implanted into the mold of the third injection molding part 22, and molten plastic slurry is injected into the mold to form the third injection molding part 22 at the connection and adjacent position of the first base 23 and the liquid storage shell 24, and the third injection molding part 22 covers the connection gap between the first base 23 and the liquid storage shell 24, so that the third injection molding part 22 is sealed by welding with the first base 23 and the liquid storage shell 24, and the sealing effect is better to prevent leakage of the atomized medium.

[0123] Step S4: The battery 72 is respectively abutted and electrically connected to the first circuit board 71 and the second circuit board 73; and installed in the power supply shell 6; and the second base seal 5 is used to cover the first circuit board 71 and the power supply shell 6 for assembly, and implanted into the mold of the fourth injection molded part 9 to injection mold the fourth injection molded part 9, so that the second base 5 and the power supply shell 6 are sealed and fused together.

[0124] Specifically, the battery 72 is respectively abutted against and electrically connected to the first circuit board 71 and the second circuit board 73; then the power supply assembly 7 is placed in the power supply shell 6 and the power supply base 5 is riveted, and implanted in the mold of the power supply injection molding 9, and the power supply injection molding 9 is molded at the connection position and adjacent position of the power supply shell 6 and the power supply base 5, so that the power supply injection molding 9 is fused and sealed with the power shell 6 and the power supply base 5 to form an integral molding, which can ensure the stable position and stable electrical connection of the battery, the first circuit board 71, and the second circuit board 73, reduce the phenomenon of poor electrical connection, and improve production efficiency and reduce costs.

[0125] The above steps S1 to S4 are performed in no particular order.

[0126] The molding method of the electronic atomization device above forms an integrated structure by injection molding of a part of the structure, which eliminates the need for reassembly, thereby saving assembly steps and reducing labor costs.
