Moreover, the two side surfaces of the electrode portion are respectively in contact with the opposite side walls of the first positioning groove, realizing double-sided contact, so that the contact area is relatively large, which can improve the connection reliability between the electrode member and the heating element, and at the same time make the contact resistance between the electrode member and the heating element relatively small. In addition, since both electrode members are fixed on the base, the two electrode portions can be inserted into the two first positioning grooves synchronously, avoiding uneven stress on the heating element caused by sequential insertion, and thus avoiding deformation of the heating element.

[0033] Embodiment:

[0034] Please refer to Figures 1 to 4 , an embodiment of the present invention provides an electronic atomization device, including a liquid storage assembly, an atomization assembly and a power supply assembly. The atomization assembly is respectively connected to the liquid storage assembly and the power supply assembly. The liquid storage assembly is used for storing atomization liquid, the atomization assembly is used for heating and atomizing the atomization liquid, and the power supply assembly is used for supplying power to the heating assembly; wherein, the atomization liquid can be water, liquid medicine, e-liquid, etc. In a specific example, the atomization liquid is e-liquid, the liquid storage assembly can be an oil cup assembly, the power supply assembly can be a battery rod assembly, and the atomization assembly is used for heating the e-liquid to atomize and generate aerosol for the user to inhale.

[0035] Please refer to Figure 1 、 Figure 3 and Figure 4 , the atomizing assembly includes a base 1, an electrode member 2, a heating element 3 and an electrode sleeve 4. There are two electrode members 2, and the two electrode members 2 are fixedly spaced on the base 1. One end of the electrode member 2 away from the base 1 is provided with a first positioning groove 221, and the first positioning groove 221 penetrates the end face and the outer peripheral surface of the end of the electrode member 2 away from the base 1; both ends of the heating element 3 are provided with two electrode portions 31 respectively inserted into the two first positioning grooves 221, and the thickness of the electrode portion 31 is less than or equal to the groove spacing of the first positioning groove 221; there are two electrode sleeves 4, and one end of the two electrode members 2 away from the base 1 is respectively axially inserted and assembled in the two electrode sleeves 4. The electrode sleeve 4 is provided with a first positioning structure, and one end of the electrode member 2 away from the base 1 is provided with a second positioning structure. The first positioning structure and the second positioning structure cooperate with each other to form a circumferential squeezing force applied to the electrode member 2 and directed inward, so that the electrode member 2 clamps the electrode portion 31.

[0036] When the electrode member 2 is inserted into the electrode sleeve 4, the first positioning structure and the second positioning structure can cooperate with each other to convert the axial force during the insertion process into a circumferential squeezing force applied to the electrode member 2 and directed inward. The circumferential squeezing force will be transmitted to the position where the electrode member 2 contacts the electrode portion 31, so that the electrode member 2 clamps and presses the electrode portion 31, so that the heating element 3 and the electrode member 2 are in contact connection without welding. And when the two side surfaces of the electrode portion 31 are respectively in contact with the opposite side walls of the first positioning groove 221, the clamping of the heating element 3 by the electrode member 2 is very firm, realizing a firm ohmic connection between the electrode member 2 and the heating element 3; moreover, the two side surfaces of the electrode portion 31 are respectively in contact with the opposite side walls of the first positioning groove 221, realizing double-sided contact, so that the contact area is larger, which can improve the connection reliability between the electrode member 2 and the heating element 3, and at the same time make the contact resistance between the electrode member 2 and the heating element 3 smaller. In addition, since the two electrode members 2 are both fixed on the base 1, the two electrode portions 31 can be synchronously inserted into the two first positioning grooves 221, avoiding uneven force on the heating element 3 caused by sequential insertion, thereby avoiding deformation of the heating element 3.

[0037] It should be noted that the electronic atomization device for generating aerosol is generally slender (ultra-thin) and has sufficient space in the length direction, but there is no space to realize the clamping (squeezing) function in the thickness direction. However, the technical solution provided by the embodiments of the present invention can realize the stable welding-free connection process between the electrode member 2 and the heating element 3 without changing the ultra-thin structure of the electronic atomization device; moreover, the technical solution provided by the embodiments of the present invention can be implemented without adding the number of components and only by modifying the original structure; the electrode member 2 is made of metal, and based on the similar coefficient of thermal expansion of the metal when the heating element 3 works, the clamping force is affected by thermal expansion and contraction, so as to ensure that a sufficient large clamping force is provided to clamp the heating element 3.

[0038] Please refer to Figure 1 , the distance between the two electrode members 2 is equal to the distance between the two electrode portions 31, so as to ensure that the two electrode portions 31 can be synchronously and respectively inserted into the two first positioning grooves 221; wherein, the distance between the two electrode members 2 is the longitudinal distance, and the distance between the two electrode portions 31 is the longitudinal distance between the contact positions of the two electrode portions 31 in the two first positioning grooves 221.

[0039] Please refer to Figure 1 and Figure 2 , the base 1 is provided with two mounting holes 11 distributed at intervals, and the two electrode members 2 are respectively mounted in the two mounting holes 11, so that the two electrode members 2 can synchronously move with the base 1 by applying force to the base 1, ensuring that both ends of the heating element 3 are synchronously inserted into the two first positioning grooves 221.

[0040] Please refer to Figure 1 and Figure 2 , the electrode member 2 includes a first positioning portion 21 and an extension portion 22 fixed to the first positioning portion 21. The mounting hole 11 penetrates through both end faces of the base 1 and forms a second positioning groove 12 on the end face of the base 1 far from the heating element 3. The second positioning groove 12 is adapted to the first positioning portion 21, and the first positioning portion 21 is assembled in the second positioning groove 12. One end of the extension portion 22 far from the first positioning portion 21 is inserted and assembled in the electrode sleeve 4. Specifically, the first positioning portion 21 can be a circular plate, and the second positioning groove 12 can be a circular groove. The circular plate is embedded in the circular groove, thereby fixing the electrode member 2 on the base 1; the extension portion 22 can be a cylinder, the extension portion 22 is fixed to one side plate surface of the first positioning portion 21 close to the base 1, and the extension portion 22 extends away from the base 1 to be inserted into the electrode sleeve 4. A first positioning groove 221 is provided at one end of the extension portion 22 far from the base 1. It should be understood that both the first positioning portion 21 and the extension portion 22 are conductors.

[0041] Please refer to Figure 2 and Figure 4, the diameter of the end of the extension portion 22 located within the mounting hole 11 and connected to the first positioning portion 21 is greater than the diameter of the end of the extension portion 22 remote from the first positioning portion 21, which can prevent the extension portion 22 from wobbling within the mounting hole 11, thereby enhancing the connection firmness between the electrode member 2 and the base 1. The extension portion 22 is eccentrically arranged relative to the first positioning portion 21, such that the two mounting holes 11 on the base 1 are arranged in one-to-one correspondence with the two electrode members 2, preventing misalignment of the electrode members 2 during installation, thereby playing an anti-fooling role.

[0042] In some embodiments, the electrode member 2 is made of metal, such as copper-based (brass, pure copper), iron-based (stainless steel), nickel-based (pure nickel), aluminum-based (pure aluminum), and is formed by cold heading or turning. The resistivity of the electrode member 2 is less than 1×10−6 Ω·m, and the electrode resistance is less than 0.1 Ω after being connected in series with the heating element. The electrode sleeve 4 can be made of a metal material or a plastic material. When the end of the electrode member 2 remote from the base 1 is electrically connected to the power supply assembly, the electrode sleeve 4 can be made of a metal material or have an insulating end face made of a plastic material. When the electrode sleeve 4 is made of a plastic material, the end face of the electrode sleeve 4 remote from the electrode member 2 has an opening, such that the end of the electrode member 2 remote from the base 1 is exposed to directly contact the conductive lead of the power supply assembly. When the end of the electrode member 2 connected to the base 1 is electrically connected to the power supply assembly, the electrode sleeve 4 can be made of a metal material or a plastic material.

[0043] Please refer to Figure 1 , Figure 3 and Figure 4 , the first positioning structure includes a positioning cavity 41 provided within the electrode sleeve 4, and the diameter of the end of the positioning cavity 41 closer to the electrode member 2 is greater than the diameter of the end farther from the electrode member 2; the second positioning structure includes a second positioning portion 23 provided at the end of the electrode member 2 remote from the base 1, and the second positioning portion 23 is axially inserted and assembled within the positioning cavity 41, so that the axial force during the insertion process can be converted into a circumferential squeezing force applied to the electrode member 2 and directed inward, thereby clamping the heating element 3 within the first positioning groove, achieving a stable and reliable connection between the electrode member 2 and the heating element 3.

[0044] In some embodiments, such as Figure 3As shown, the diameters of the positioning cavity 41 and the second positioning portion 23 both gradually decrease along the insertion direction. For example, both the positioning cavity 41 and the second positioning portion 23 are conical. The second positioning portion 23 and the positioning cavity 41 are adapted to each other, that is, the conical surface angles of the second positioning portion 23 and the positioning cavity 41 are the same, and the diameter of the second positioning portion 23 at the end close to the electrode sleeve 4 is smaller than the diameter at the end far from the electrode sleeve 4, and the diameter of the positioning cavity 41 at the end close to the electrode member 2 is larger than the diameter at the end far from the electrode member 2. Thus, during the insertion of the electrode member 2 into the electrode sleeve 4, the electrode sleeve 4 can abut against the second positioning portion 23 to generate a circumferential extrusion force, promoting the tight connection between the heating element 3 and the electrode member 2 and preventing poor contact.

[0045] Preferably, the second positioning portion 23 is coaxially arranged with the positioning cavity 41. At least one limiting plane is provided on the outer side of the second positioning portion 23, and there is an included angle between the limiting plane and the central axis of the second positioning portion 23, so that the limiting plane can limit the relative rotation of the second positioning portion 23 in the positioning cavity 41 with respect to the electrode sleeve 4, thereby realizing the positioning of the electrode member 2. According to actual needs, one limiting plane can be provided, or two, three, etc. can be provided, and multiple limiting planes can be continuously distributed or spaced apart. The included angle between the limiting plane and the central axis of the second positioning portion 23 can be 10°, 15°, 20°, etc. The second positioning portion 23 can be square, circular, or other complex special shapes, such as polygons.

[0046] In some other embodiments, the positioning cavity 41 can be a stepped cavity, and the cooperation between the second positioning portion 23 and the stepped cavity can also form a circumferential extrusion force applied to the electrode member 2 and directed inward, so as to clamp the heating element 3 by the electrode member 2.

[0047] Please refer to Figure 1 and Figure 3 , an exhaust cavity 42 is further provided in the electrode sleeve 4. The exhaust cavity 42 penetrates through the end of the electrode sleeve 4 far from the electrode member 2, and the exhaust cavity 42 communicates with the positioning cavity 41. The provision of the exhaust cavity 42 can discharge the air in the positioning cavity 41, thereby reducing the difficulty of inserting the second positioning portion 23 into the positioning cavity 41 and improving the smoothness of the insertion of the second positioning portion 23.

[0048] It should be noted that in the axial direction, the length of the positioning cavity 41 is greater than the length of the second positioning portion 23, which can not only ensure that the positioning cavity 41 has enough space to accommodate the second positioning portion 23, but also is beneficial to discharging air.

[0049] Please refer to Figure 1 and Figure 4, in some embodiments, the opposite side walls of the first positioning groove 221 are arranged in parallel, and in the insertion direction of the electrode member 2, the distance gradient between the opposite side walls of the first positioning groove 221 increases or remains unchanged. Specifically, when the distance gradient between the opposite side walls of the first positioning groove 221 increases, the groove pitch of the first positioning groove 221 is multiple widths. At this time, the distance between the opposite side walls at the end of the first positioning groove 221 close to the electrode sleeve 4 is greater than the distance between the opposite side walls at the end far from the electrode sleeve 4, which is beneficial to both inserting the heating element 3 into the first positioning groove 221 and clamping the heating element 3 by the electrode member 2; when the distance between the opposite side walls of the first positioning groove 221 remains unchanged, it is beneficial to the formation of the first positioning groove 221.

[0050] In other embodiments, the opposite side walls of the first positioning groove 221 have an included angle, and in the insertion direction of the electrode member 2, the distance between the opposite side walls of the first positioning groove 221 gradually increases. At this time, the opposite side walls of the first positioning groove 221 are inclined surfaces, that is, the first positioning groove 221 forms a flared opening on the electrode member 2, which is beneficial to both inserting the heating element 3 into the first positioning groove 221 and clamping the heating element 3 by the electrode member 2.

[0051] It should be noted that the ratio range of the groove pitch of the first positioning groove 221 to the thickness of the electrode portion 31 is within 1:1 - 1:5. For example, 1:1, 1:1.5, 1:2, 1:3, 1:5, etc. Among them, the thickness of the electrode portion 31 is between 0.06 mm and 0.2 mm. For example, 0.06 mm, 0.08 mm, 0.1 mm, 0.15 mm, 0.2 mm, etc.

[0052] Please refer to Figure 1 and Figure 4 , the top end of the first positioning groove 221 penetrates the end face of the electrode member 2 far from the base 1, and the bottom end is located inside the electrode member 2; the electrode portion 31 is located between the top end and the bottom end of the first positioning groove 221, thereby further ensuring the connection stability between the heating element 3 and the electrode member 2 and realizing the tight ohmic connection between the electrode member 2 and the heating element 3.

[0053] Please refer to Figure 1 and Figure 4, the ratio of the groove pitch of the first positioning groove 221 to the difference between the groove pitch of the first positioning groove 221 and the thickness of the electrode portion 31 is greater than or equal to the ratio of the distance between the longitudinal center of the electrode portion 31 and the top end of the first positioning groove 221 to the distance between the longitudinal center of the electrode portion 31 and the bottom end of the first positioning groove 221; wherein, the longitudinal center of the electrode portion 31 is the middle position of the side plate surface of the electrode portion 31 in contact with the electrode member 2. For example, if the groove pitch of the first positioning groove 221 is 0.1 mm, the thickness of the electrode portion 31 is 0.08 mm, the distance between the electrode portion 31 and the top end of the first positioning groove 221 is 20 mm, and the distance between the electrode portion 31 and the bottom end of the first positioning groove 221 is 4 mm, then the ratio of the groove pitch of the first positioning groove 221 to the difference between the groove pitch of the first positioning groove 221 and the thickness of the electrode portion 31 is 0.1 / (0.1 - 0.08) = 5, thereby ensuring the connection stability between the heating element 3 and the electrode member 2.

[0054] Please refer to Figure 1 , the electrode portion 31 is provided with a positioning hole 311. The positioning hole 311 is located at one end of the electrode portion 31 connected to the heating portion. The positioning hole 311 is used to position the heating element 3, so as to facilitate the insertion of the electrode portion 31 into the first positioning groove 221; moreover, during the process of the electrode portion 31 being clamped by the electrode member 2, the force conduction along the heating sheet to the middle position of the heating element 3 can be interrupted, avoiding deformation of the heating element 3, and thus playing a supporting role.

[0055] Please refer to Figure 1 , the atomization assembly further includes an oil guide cotton 5. The oil guide cotton 5 is attached to one side of the heating element 3; wherein, the oil guide cotton 5 is attached to one side surface of the heating portion. The oil guide cotton 5 is used to introduce the atomization liquid for the heating portion to heat and atomize to generate aerosol.

Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
