Therefore, the features defined as "first", "second", "third", etc. can explicitly or implicitly include one or more of the features. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.

[0047] Figures 1 to 3 An electronic atomization device 100 of an embodiment of the utility model is shown, and the electronic atomization device 100 can be used to atomize a liquid atomization matrix to generate an aerosol, and the aerosol can be inhaled or inhaled by a user. The liquid atomization matrix can include tobacco oil or liquid medicine, etc. The electronic atomization device 100 has the characteristics of good conductive contact stability and is easy to install.

[0048] like Figures 1 to 3 As shown, the electronic atomization device 100 includes an atomizer 10 and a power supply assembly 20. The atomizer 10 is used to atomize a liquid atomization matrix. The power supply assembly 20 is mechanically and / or electrically connected to the atomizer 10 to supply power to the atomizer 10.

[0049] like Figure 2As shown, the power supply assembly 20 includes a power supply housing 201, a power supply 202 installed in the power supply housing 201, a positive electrode conductive part 203 for leading out the positive electrode of the power supply 202, and a negative electrode conductive part 204 for leading out the negative electrode of the power supply 202. It can be understood that the positive electrode conductive part 203 and the negative electrode conductive part 204 are connected to the positive electrode and the negative electrode of the power supply 202 respectively, and the positive electrode and the negative electrode of the power supply 202 are led out to one end of the power supply assembly 20, so as to facilitate contact and conduction with the atomizer 10. Among them, the positive electrode conductive part 203 and the negative electrode conductive part 204 can be implemented by structures such as electrode columns.

[0050] like Figures 4 to 6 As shown, the atomizer 10 includes an atomizing shell 1, a seat assembly 2, an atomizing core 3 and an electrode connector 4. The atomizing shell 1 includes a shell body 11, an airway tube 12 and a nozzle 13. The shell body 11 may be cylindrical, the airway tube 12 is arranged inside the shell body 11, and the airway tube 12 is located at the central axis of the shell body 11. The airway tube 12 has a first through hole 121 that is axially penetrated. The upper end of the shell body 11 is connected to the upper end of the airway tube 12. The nozzle 13 may be flat cylindrical and is arranged at one end of the shell body 11 connected to the airway tube 12. The nozzle 13 is located at the central axis of the shell body 11. The nozzle 13 has a second through hole 131 that is axially penetrated and connected to the first through hole 121. The first through hole 121 and the second through hole 131 together constitute the air outlet channel 14 of the atomizer 10.

[0051] The seat assembly 2 is installed in the atomizing shell 1 and is located below the airway tube 12 and connected to the lower end of the airway tube 12. The inner wall surface of the shell body 11, the outer wall surface of the airway tube 12, and the upper end of the seat assembly 2 jointly define a liquid storage chamber 5 for storing liquid atomizing matrix.

[0052] The atomizer core 3 and the electrode connector 4 are arranged in the seat assembly 2. In this embodiment, at least two atomizer cores 3 are provided. It can be understood that by providing at least two atomizer cores 3, the following advantages are achieved: 1. The at least two atomizer cores 3 can work simultaneously, so that the liquid atomization matrix is ​​fully heated and atomized in a shorter time, thereby providing a more concentrated and delicate aerosol; 2. A larger aerosol output can be generated to meet the user's demand for aerosol output; 3. When an atomizer core 3 has a problem or is blocked, the other atomizer cores 3 can continue to work, ensuring the normal use of the electronic atomizer device 100, and improving the stability and reliability of the electronic atomizer device 100; 4. The working pressure of a single atomizer core 3 can be reduced, thereby extending the service life of the electronic atomizer device 100.

[0053] Combination Figure 4 , Figure 7 and Figure 8As shown, the atomizing core 3 may include a liquid-conducting body and a heating element. The liquid-conducting body may be a ceramic porous body but is not limited to a ceramic porous body. The liquid-conducting body has a liquid absorption surface 31 connected to the liquid storage chamber 5. The heating element may be arranged on the other surface of the liquid-conducting body to form an atomizing surface 32. The heating element may be a heating wire but is not limited to a heating wire. The heating element may include a current input terminal 33 and a current output terminal 34. The current input terminal 33 and the current output terminal 34 are respectively used to connect to the positive electrode and the negative electrode of the power supply 202, that is, they are respectively used to be in conductive contact with the positive conductive part 203 and the negative conductive part 204.

[0054] It can be understood that, for example, when the heating element is a heating wire arranged in an S shape, by setting the two ends of the heating wire as the current input end 33 and the current output end 34 respectively, when the current input end 33 and the current output end 34 of the heating wire are in conductive contact with the positive conductive part 203 and the negative conductive part 204 respectively, a heating circuit is formed between the power supply 202 and the heating wire, and the heating wire is energized and heated to heat the liquid atomization matrix and atomize it to generate an aerosol.

[0055] Combination Figure 4 , Figure 6 , Figure 7 and Fig. 9 As shown, the electrode connector 4 is used to connect the heating elements of the at least two atomizer cores 3 with the power source 202. In this embodiment, one end of the electrode connector 4 is provided with a first contact portion 41 to contact and conduct with the electrode of the power source 202; the other end of the electrode connector 4 is provided with at least two second contact portions 42, and the at least two second contact portions 42 are respectively contacted and conducted with the current input terminals 33 or the current output terminals 34 of the at least two atomizer cores 3.

[0056] The first contact portion 41 is used to contact and conduct with the positive conductive portion 203 or the negative conductive portion 204 of the power supply assembly 20. Among them, the first contact portion 41 of the electrode connector 4 can be provided with one to connect with one electrode of the power supply 202. It can be understood that the use of one electrode connector 4 can achieve contact and conduction between at least two atomizer cores 3 and one electrode of the power supply 202, and one electrode connector 4 can be connected to one electrode of the power supply 202 only through one first contact portion 41, which reduces the contact points, thereby improving stability and facilitating assembly.

[0057] In this embodiment, at least two atomizer cores 3 are arranged at intervals, and the second contact portion 42 of the electrode connector 4 abuts between the at least two atomizer cores 3, so that the electrode connector 4 is in contact and conduction with the at least two atomizer cores 3 through the at least two second contact portions 42, and at the same time, it supports the at least two atomizer cores 3, making the contact more stable.

[0058] In this embodiment, the atomizer 10 includes two atomizer cores 3 and two electrode connectors 4 arranged at intervals, and one electrode connector 4 may include a first contact portion 41 and two second contact portions 42. It can be understood that the number of the second contact portions 42 of each electrode connector 4 is the same as the number of the atomizer cores 3, so that the second contact portions 42 in one electrode connector 4 are in contact and conduction with the atomizer cores 3 in a one-to-one correspondence. Of course, in other embodiments, the atomizer 10 may include three or more atomizer cores 3.

[0059] Combination Figure 4 , Figure 7 and Fig. 9 As shown, the two atomizer cores 3 can be arranged opposite to each other, and the two second contact portions 42 on the same electrode connector 4 can be arranged on the same straight line and connected, and the two atomizer cores 3 are respectively perpendicular to the second contact portions 42 of the two electrode connectors 4 (as shown in FIG. Figure 7 As shown), the forces on the two atomizer cores 3 are balanced and uniform, and the contact is more stable.

[0060] Alternatively, the conductive contact state between the two atomizing cores 3 and the two electrode connectors 4 can also be set as follows: Fig.14 As shown, the two atomizing cores 3 are parallel to each other; or Fig.15 As shown, the second contact portions 42 of the two electrode connectors 4 are parallel to each other; or Fig.16 As shown, the two atomizer cores 3 are parallel to each other, and the second contact portions 42 of the two electrode connectors 4 are parallel to each other. It can be understood that when the two atomizer cores 3 or one of the two electrode connectors 4 are parallel to each other, the other can be arranged at an angle to each other; when the two atomizer cores 3 are parallel to each other, and the second contact portions 42 of the two electrode connectors 4 are parallel to each other at the same time, the atomizer core 3 and the second contact portion 42 of the electrode connector 4 can be arranged at an angle. The above-mentioned arrangement can achieve contact and conduction between the two electrode connectors 4 and the two atomizer cores 3.

[0061] The second contact portion 42 forms a surface contact with the atomizer core 3. It can be understood that the atomizer core 3 uses a local surface of the area where the current input terminal 33 and the current output terminal 34 are located as a contact surface to contact the second contact portion 42. The second contact portion 42 is in contact and conduction with the atomizer core 3 through its end surface opposite to the contact surface of the atomizer core 3. Therefore, the second contact portion 42 and the atomizer core 3 are in surface contact, and the end surface of the second contact portion 42 is adapted to the contact surface on the atomizer core 3, so that the contact between the two is stable and reliable.

[0062] The two surfaces can be adapted to each other in the following manner: when the contact surface of the atomizer core 3 is parallel to the axial direction of the atomizer 10, the end surface of the second contact portion 42 is also arranged parallel to the axial direction of the atomizer 10; when the contact surface of the atomizer core 3 is inclined relative to the axial direction of the atomizer 10, the end surface of the second contact portion 42 is also inclined correspondingly relative to the axial direction of the atomizer 10. It can be understood that when the end surface of the second contact portion 42 is parallel to the contact surface of the atomizer 10, the two are adapted. Of course, the two surfaces can also be arranged in an arc surface. For example, when the contact surface of the atomizer core 3 is arranged in a concave surface, the end surface of the second contact portion 42 can be arranged in a convex surface adapted to the concave surface, so that the contact effect of the two surfaces is good, and the contact is stable and reliable.

[0063] Combination Figure 2 , Figure 7 As shown, the atomizer 10 includes two electrode connectors 4 arranged at intervals, wherein the first contact portion 41 of one electrode connector 4 is used to contact and conduct with the positive electrode of the power source 202, and the second contact portion 42 is used to contact and conduct with the current input terminal 33 of the atomizer core 3; the first contact portion 41 of the other electrode connector 4 is used to contact and conduct with the negative electrode of the power source 202, and the second contact portion 42 is used to contact and conduct with the current output terminal 34 of the atomizer core 3.

[0064] Each electrode connector 4 includes a first contact portion 41 and two second contact portions 42. Therefore, conductive contact between the two atomizer cores 3 and the positive and negative electrodes of the power source 202 can be achieved through the two electrode connectors 4, and one electrode connector 4 is only in contact with the positive or negative electrode of the power source 202 through one first contact portion 41, which is convenient for assembly.

[0065] It is understandable that in other embodiments, the electrode connector 4 may be provided with one, for example, the electrode connector 4 is in conductive contact with the current input terminals 33 of the two atomizer cores 3 through its two second contact parts 42, and is in contact with the positive electrode of the power supply 202 through its first contact part 41; the current output terminals 34 of the two atomizer cores 3 may be conductively connected to the negative electrode of the power supply 202 through two wires. The electrode connector 4 may also be provided with three or more, for example, when the electrode connector 4 is provided with three, each electrode connector 4 is in conductive contact with the current input terminals 33 of the two atomizer cores 3 through its two second contact parts 42, the first contact part 41 of one electrode connector 4 is in contact with the positive electrode of the power supply 202, and the first contact parts 41 of the two electrode connectors 4 are connected together and in contact with the negative electrode of the power supply 202. It is understandable that by providing three or more electrode connectors 4, the contact and support effects of the two atomizer cores 3 are better.

[0066] Combination Figure 4 , Figure 6 , Figures 10 to 12As shown, the seat body assembly 2 includes a base 21, which is installed in the shell body 11 and blocks the assembly port at one end of the shell body 11 away from the suction nozzle 13. The base 21 is provided with a bottom wall 211 and a circumferential wall 212 surrounding the bottom wall 211. The electrode connector 4 is passed through the bottom wall 211 of the base 21, and the first contact portion 41 is bent to cooperate with the bottom surface of the bottom wall 211.

[0067] Combination Fig. 9 As shown, the first contact portion 41 is bent and arranged at an angle, and includes a limiting section 412 , which is limitedly matched with the bottom surface of the bottom wall 211 , and the second contact portion 42 is located on a side of the base 21 away from the bottom surface.

[0068] The first contact portion 41 further includes a reinforcing section 411 located on one side of the limiting section 412 close to the second contact portion 42 . The width of the reinforcing section 411 may be greater than or equal to the width of the limiting section 412 . The width of the reinforcing section 411 is relatively wide and plays a reinforcing role.

[0069] Specifically, the reinforcing section 411 and the limiting section 412 are perpendicular to each other and are arranged in an L shape, and the second contact portion 42 and the reinforcing section 411 are located on the same plane. Fig.11 and Fig.12 As shown, a through installation groove 2111 is provided on the bottom wall 211, and the width of the limiting section 412 in the thickness direction c of the atomizer 10 is greater than the width of the installation groove 2111. During assembly, the second contact portion 42 of the electrode connector 4 and the reinforcement section 411 pass through the installation groove 2111 from bottom to top from one side of the bottom surface of the bottom wall 211, and the limiting section 412 is limitedly matched with the bottom wall 211 on the bottom surface of the bottom wall 211, thereby limiting the upward movement of the electrode connector 4 in the axial direction of the electronic atomization device 100.

[0070] The bottom wall 211 is provided with an air inlet 2112, which is located between the first contact portions 41 of the two electrode connectors 4. It can be understood that the air inlet 2112 is used to allow external air to enter the atomization chamber 6 to mix with the aerosol in the atomization chamber 6 and then be output to the outside.

[0071] Specifically, Fig. 9 As shown, the first contact portion 41 further includes an extension section 413 connected to the limiting section 412, and the extension section 413 is used to connect to the electrode of the power source 202. The first contact portion 41 is arranged away from the air inlet 2112 (combined with Fig.10 As shown), the extension sections 413 of the two electrode connectors 4 are respectively located on both sides of the air inlet hole 2112.

[0072] Combination Figure 1 and Figure 6 As shown, it can be understood that the electronic atomization device 100 includes a height direction a, a width direction b and a thickness direction c, combined with Figures 10 to 12 As shown, the mounting grooves 2111 can be respectively arranged on both sides of the thickness direction c of the bottom wall 211, the limiting sections 412 of the two electrode connectors 4 are respectively located on both sides of the thickness direction c of the bottom wall 211, and the air inlet 2112 is arranged between the two mounting grooves 2111 and can be centrally arranged on the bottom wall 211.

[0073] The extension section 413 and the limiting section 412 are located on the same plane, and the extension section 413 and the limiting section 412 are arranged in an L shape. The extension sections 413 of the two electrode connectors 4 are respectively arranged on both sides of the width direction b of the air inlet 2112. It can be understood that the setting of the extension section 413 is exposed on the bottom surface of the bottom wall 211, and it can be connected to the power supply 202 through a side away from the bottom surface of the bottom wall 211, which is convenient for connecting with the electrode of the power supply 202; at the same time, the electrode connector 4 avoids the air inlet 2112 to avoid affecting the air intake. It can be understood that the positive conductive part 203 and the negative conductive part 204 on the power supply 202 play a role in limiting the downward movement of the electrode connector 4 in the axial direction.

[0074] It can be understood that the positive conductive part and the negative conductive part in the power supply assembly of the single atomization core 3 in the prior art are respectively located on both sides of the width direction b of the power supply assembly. Therefore, in this embodiment, by respectively arranging the two extension sections 413 on both sides of the width direction b of the air inlet hole 2112, the atomizer 10 of this embodiment can share the power supply assembly with the atomizer 10 of the single atomization core 3 in the prior art.

[0075] In this embodiment, the electrode connector 4 is an integrally formed structure, which can be formed by a stamping and bending process using a conductive material, such as a conductive metal. The electrode connector 4 has the characteristics of high production efficiency and low cost.

[0076] Combination Figure 5 , Fig.10 , Fig.12 and Fig.13 As shown, the bottom surface of the bottom wall 211 of the base 21 is further provided with an anti-short circuit spacer 2113, and the anti-short circuit spacer 2113 is blocked between the first contact portions 41 of the two electrode connectors 4. Specifically, the bottom wall 211 is provided with a receiving groove 2114 on the bottom surface, and the limiting sections 412 and the extension sections 413 of the two electrode connectors 4 are installed in the receiving groove 2114, and the limiting section 412 of one electrode connector 4 is arranged close to the extension section 413 of the other electrode connector 4.

[0077] Two anti-short circuit spacers 2113 are formed in the receiving groove 2114, and the two anti-short circuit spacers 2113 can be respectively arranged between the limiting section 412 of one electrode connector 4 and the extending section 413 of another electrode connector 4. It can be understood that the anti-short circuit spacers 2113 are made of insulating material, and by separating the two electrode connectors 4, the two electrode connectors 4 can be prevented from contacting and short-circuiting. Among them, the base 21 is an integrally formed structure, and can be made of plastic.

[0078] Combination Figure 4 and Fig. 9 As shown, the atomizer 10 also includes an atomization chamber 6 formed between the two atomization cores 3, the atomization chamber 6 is formed in the seat assembly 2, and is located above the air inlet hole 2112 and communicated with the air inlet hole 2112. The two electrode connectors 4 also include a connecting portion 43, the connecting portion 43 is connected between the reinforcement section 411 and the two second contact portions 42, the connecting portion 43 and the reinforcement section 411 and the second contact portion 42 are located on the same plane, and the second contact portion 42, the connecting portion 43 and the reinforcement section 411 may be in an I-shape, and the width of at least the portion of the connecting portion 43 located in the atomization chamber 6 is smaller than the width of the two second contact portions 42 and the width of the reinforcement section. It can be understood that the width of the connecting portion 43 in the width direction b of the atomizer 10 and located in the atomization chamber 6 is smaller than the width of the two second contact portions 42 and the reinforcement section 411. Through the local fine design, excessive metal can be effectively prevented from affecting the temperature of the atomization chamber 6; at the same time, the surface area of ​​the connecting portion 43 is small, so that the contact area with the aerosol in the atomization chamber 6 is small, thereby reducing the formation of condensate.

[0079] Combination Figure 4 and Figure 6 As shown, the atomizer 10 further includes a fixing seat 22, the fixing seat 22 is provided with a receiving groove 221, and the atomizer core 3 is installed in the receiving groove 221.

[0088] The seat assembly 2 further includes a second sealing member 25, which is sleeved on the upper end surface of the first sealing member 24 and sleeved together on the outer periphery of the side of the two fixing seats 22 away from the central axis of the atomizer 10, and a snap-fit ​​structure is provided between the side of the second sealing member 25 and the side of the fixing seat 22. The second sealing member 25 is provided with a second liquid hole 251 corresponding to the first liquid hole 241 of the first sealing member 24, and a second air hole 252 corresponding to the first air hole 242.

[0089] The seat assembly 2 also includes a third sealing member 26 that is sealed between the inner wall of the shell body 11, the base 21, the fixed seat 22 and the airway tube 12.

The second sleeve portion 262 is disposed between the outer wall surface of the airway tube 12 and the second sealing member 25, and the second sleeve portion 262 cooperates with the first sealing member 24 and the second sealing member 25, so that the air outlet channel 14 is sealed and connected to the atomization chamber 6.

[0090] The third sleeve portion 263 wraps the base 21 , the fixing base 22 , the first sealing member 24 , the second sealing member 25 and other components in the circumferential direction, and seals the gap between the inner wall of the shell body 11 and other components to prevent liquid leakage.

[0091] The second sleeve portion 262 of the third sealing member 26 surrounds a third air hole 264 corresponding to the second air hole 252, and the first sleeve portion 261 is provided with a third liquid hole 265 corresponding to the second liquid hole 251. It can be understood that the first sealing member 24 and the second sealing member 25 are independently provided for easy assembly; of course, the first sealing member 24 and the second sealing member 25 can also be provided in an integrated structure.

[0092] In this embodiment, a ventilation structure may also be provided in the atomizer 10, and the ventilation structure includes a ventilation channel, which connects the outside world with the liquid storage chamber 5, so that the outside air can enter the liquid storage chamber 5, maintain the air pressure balance in the liquid storage chamber 5, and enable the atomizer core 3 to be continuously supplied with liquid.
