Description

Technical Field

[0001] This application relates to the field of electronic atomization device technology, and in particular to an electronic atomizer and its bottom cover assembly. Background Technology

[0002] In existing electronic atomizing devices, the leads extending from the heating wire are directly soldered to the battery and circuit board via wires. Since the heating wire leads are typically made of nickel and are very thin, and the conductors are made of copper and are also very thin, this soldering method results in unstable connections that are prone to detachment, leading to open circuits and malfunction. Furthermore, the heating wire leads and conductors are made of flexible materials and cannot be fixed in place. During the soldering process, the heating wire is easily deformed due to pulling, ultimately leading to burnt coils and a poor flavor. Summary of the Invention

[0003] The main technical problem this application addresses is preventing the heating wire from easily deforming when connected to other components via wires, thus ensuring a good taste output.

[0004] To solve the above-mentioned technical problems, one technical solution adopted in this application is to provide a bottom cover assembly for an electronic atomizer. The bottom cover assembly includes: a bottom cover; a first electrode, which is integrally formed with the bottom cover and partially penetrates the bottom cover so that the first electrode is exposed on both opposite sides of the bottom cover; and a second electrode, which is connected to the bottom cover and partially penetrates the bottom cover, and is spaced apart from the first electrode; wherein the first electrode and the second electrode are both hard electrodes.

[0005] The first electrode includes: a contact ring disposed on one side of the bottom cover; and a hanging angle extending from a portion of the contact ring to the other side of the bottom cover, the hanging angle passing through the bottom cover and exposed outside the bottom cover.

[0006] There are multiple hanging corners, and the connection point with the contact ring is the inner ring of the contact ring. Adjacent hanging corners are set at equal intervals.

[0007] Among them, at least one of the hanging angles is longer than the other hanging angles, and is called a long hanging angle, which is used to connect to the conductive pin of the heating wire in the electronic atomizer.

[0008] The bottom cover has an electrode hole, and the second electrode is disposed in the electrode hole with an interference fit.

[0009] The contact ring surrounds the second electrode.

[0010] The first electrode and the bottom cover are an integral structure formed by injection molding. The first electrode is made of metal, and the bottom cover is made of insulating material.

[0011] The contact ring is only exposed on one side of the bottom cover, the second electrode is a cylindrical structure, and the diameter of the end of the second electrode on the surface of the bottom cover where the contact ring is exposed is larger than the diameter of the other end of the second electrode.

[0012] To solve the above-mentioned technical problems, another technical solution adopted in this application is to provide an electronic atomizing bullet, wherein the electronic atomizing bullet includes: an atomizing component, the atomizing component including a heating wire; a bottom cover assembly, the bottom cover assembly being any of the atomizing components described above; wherein the heating wire includes a positive electrode pin and a negative electrode pin, one of the first electrode and the second electrode is connected to the positive electrode pin of the heating wire, and the other is connected to the negative electrode pin of the heating wire.

[0013] To solve the above-mentioned technical problems, another technical solution adopted in this application is to provide an electronic atomizer, which includes a power module and an atomization module connected to each other, and the atomization module includes the bottom cover assembly described in any of the above claims.

[0014] The beneficial effects of this application are as follows: Unlike the prior art, this application provides a bottom cover assembly for an electronic atomizer, which connects the motor pins of the heating wire through electrodes set on the bottom cover, thereby avoiding the use of wires. In addition, the bottom cover can also provide a certain support to prevent pin deformation, thus maintaining a good flavor output. Attached Figure Description

[0025] This application provides an electronic atomizing cartridge where the microphone airway and airflow channel are independent. Please refer to [link / reference]. Figure 1 , Figure 1 This is a schematic cross-sectional view of an electronic atomizing cartridge according to one embodiment of this application. In this application, the electronic atomizing cartridge of the electronic atomizer includes an atomizing component 11, a bottom cover 12, a first electrode 13, a second electrode 14, a housing 15, and an oil sealing component 16.

[0026] The atomizing assembly 11 includes a heating wire 111, which has a positive electrode lead and a negative electrode lead. Both a first electrode 13 and a second electrode 14 are connected to the bottom cover 12. The first electrode 13 partially penetrates the bottom cover 12. A portion of the first electrode 13 is exposed on the surface of the bottom cover 12 away from the heating wire 111, while another portion protrudes from the surface of the bottom cover 12 facing the heating wire 111. The first electrode 13 protruding from the surface of the bottom cover 12 facing the heating wire 111 is connected to the negative electrode lead of the heating wire 111. The first electrode 13 is made of a high-hardness metal, such as copper or a copper alloy, which is not easily deformed. Therefore, it can be connected well to the negative electrode lead of the heating wire 111 without deformation, maintaining a stable connection. The second electrode 14 also has a portion exposed on the surface of the bottom cover 12 away from the heating wire 111, and another portion similarly protrudes from or is exposed on the surface of the bottom cover 12 facing the heating wire 111. The second electrode 14 is connected to the positive pin of the heating wire 111. The first electrode 13 and the second electrode 14 are spaced apart. Specifically, the first electrode 13 and the second electrode 14 pass through different positions of the bottom cover 12, with the bottom cover 12 acting as the spacer between them. Both the first electrode 13 and the second electrode 14 are rigid electrodes. In this application, a rigid electrode is defined as an electrode that will not deform when subjected to a force not exceeding 5 Newtons.

[0027] Please refer to further information. Figure 2 , Figure 2 yes Figure 1 A schematic diagram of the structure of the first electrode 13 of the electronic atomizing cartridge. In this embodiment, the first electrode 13 includes a contact ring 131 and a hanging angle 132. The contact ring 131 is disposed on the surface of the bottom cover 12 away from the atomizing component 11, and preferably is coplanar with the bottom cover 12, or slightly protrudes from the surface of the bottom cover 12 away from the atomizing component 11. The hanging angle 132 is formed by a portion of the contact ring 131 extending towards the atomizing component 11, and the hanging angle 132 passes through the bottom cover 12, is exposed outside the bottom cover 12, and is connected to the negative electrode pin of the heating wire 111. Specifically, there are multiple hanging angles 132, and the connection point with the contact ring 131 is the inner ring of the contact ring 131, and adjacent hanging angles 132 are equidistantly arranged. The length of one of the hanging angles 132 is greater than the length of the other hanging angles 132, and it is a long hanging angle 133. The long hanging angle 133 is connected to the negative electrode pin of the heating wire 111. Preferably, the hanging angle 132 is arranged perpendicular to the contact ring 131. Furthermore, the thickness of the contact ring 131 is less than the thickness of the bottom cover 12.

[0028] Please refer to further information. Figure 3 and Figure 4 , Figure 3 yes Figure 1 A schematic diagram of the structure of the bottom cover 12. Figure 4 yes Figure 1 This is a structural schematic diagram of the bottom cover 12 from another perspective. To ensure a tighter connection between the first electrode 13 and the bottom cover 12, the first electrode 13 and the bottom cover 12 can be configured as an integral structure formed by injection molding. The first electrode 13 is made of metal, and the bottom cover 12 is made of insulating material. In this embodiment, the contact ring 131 is provided with five short hanging corners 132 and one long hanging corner 133. The long hanging corner 133 connects to the negative electrode pin of the heating wire 111, while the short hanging corners 132 serve as gripping positions, facilitating sufficient positioning and glue flow during the injection molding of the first electrode 13 and the bottom cover 12. The long hanging corner 133 is the contact position for the negative electrode pin of the heating wire 111. The negative electrode pin of the heating wire 111 can be inserted into the reserved gap between the long hanging corner 133 and the plastic bottom cover 12, and then the negative electrode pin of the heating wire 111 is bent to ensure complete contact with the long hanging corner 133.

[0029] The bottom cover 12 includes a locking portion 121, a protrusion 122, a positioning post 124, and a positive electrode hole 125. The locking portion 121 is disposed on the edge of the bottom cover 12, and a locking hole 151 is formed on the edge of the housing 15 connected to the bottom cover 12. The locking portion 121 engages in the locking hole 151, thereby connecting one end of the bottom cover 12 and the housing 15, and forming an accommodating space for accommodating the atomizing component 11. The protrusion 122 is annularly arranged, and a through hole 123 is formed in the annulus to allow gas to circulate with the outside through the accommodating space formed by the bottom cover 12 and the housing 15. The positioning post 124 extends vertically from the side surface of the bottom cover 12 toward the heating wire 111. Preferably, multiple posts are provided. In this embodiment, only two are used as an example. In other embodiments, there may be one, three, or more. The positive electrode hole 125 is formed in the bottom cover 12 and penetrates through the bottom cover 12. The second electrode 14 is disposed in the positive electrode hole 125, thereby forming a structure in which the second electrode 14 penetrates the bottom cover 12. In order to ensure that the connection between the second electrode 14 and the heating wire 111 is sufficiently stable, in this embodiment, the second electrode 14 and the positive electrode lead of the heating wire 111 are clamped in the positive electrode hole 125 by an interference fit. That is, the part of the positive electrode lead away from the heating wire 111 is also disposed in the positive electrode hole 125 of the bottom cover 12.

[0030] In this embodiment, the contact ring 131 surrounds the second electrode 14. The second electrode 14 is preferably a cylinder with a gradually changing diameter. Its diameter is largest in the portion located within the positive electrode hole 125, and decreases towards the heating wire 111. That is, the second electrode 14 has a cylindrical structure, and the diameter of the end of the second electrode 14 located on the surface of the bottom cover 12 where the contact ring 131 is exposed is larger than the diameter of the other end of the second electrode 14. The diameter change of the second electrode 14 can be gradual, or it can change only at a specific location, with two or more different overall diameter lengths, or a combination of both. Preferably, the second electrode 14, the positive electrode hole 125, and the contact ring 131 are coaxially arranged. Similarly, the end of the second electrode 14 away from the heating wire 111 can be coplanar with the surface of the bottom cover 12 away from the heating wire 111, or slightly protrude from or recess into the surface of the bottom cover 12 away from the heating wire 111.

[0031] In this embodiment, the first electrode 13 is a rigid negative electrode, and the second electrode 14 is a positive electrode pin. In other embodiments, the first electrode 13 can be a positive electrode, connected to the positive pin of the heating wire 111; the second electrode 14 can be a negative electrode, connected to the negative pin of the heating wire 111. That is, one of the first electrode 13 and the second electrode 14 is a positive electrode, and the other is a negative electrode.

[0032] Please see Figure 5 , Figure 5 yes Figure 1A schematic diagram of the oil sealing component 16 is shown. The oil sealing component 16 is disposed on the side of the bottom cover 12 facing the heating wire 111, located within the accommodating space formed by the housing 15 and the bottom cover 12. The oil sealing component 16 has a fixing hole 161, a positioning hole 162, and a pin hole 163. The fixing hole 161 corresponds to the position of the long hanging angle 133, and the long hanging angle 133 is clamped in the fixing hole 161 with an interference fit to the negative electrode pin of the heating wire 111. In this embodiment, only one long hanging angle 133 is provided. When there are multiple negative electrode pins of the heating wire 111, it can be connected only to this one long hanging angle 133, or multiple long hanging angles 133 can be provided, with each long hanging angle 133 connecting to one or more negative electrode pins of the heating wire 111. The positioning hole 162 corresponds to the positioning post 124 on the bottom cover 12. The positioning post 124 on the bottom cover 12 passes through the positioning hole 162, thereby positioning the bottom cover 12 and the oil sealing member 16 to prevent them from shifting. The number of positioning holes 162 is preferably the same as the number of positioning posts 124, and the number of positioning holes 162 shall not be less than the number of positioning posts 124. The lead hole 163 corresponds to the positive lead of the heating wire 111 to allow the positive lead of the heating wire 111 to pass through, thereby enabling the positive lead of the heating wire 111 to be connected to the second electrode 14. In other embodiments, if the negative lead of the heating wire 111 is connected by inserting it into the gap between the reserved long hanging angle 133 and the plastic bottom cover 12, and then bending the negative lead of the heating wire 111 to ensure complete contact with the long hanging angle 133, then the lead hole 163 needs to be set to at least two and spaced apart from each other, corresponding to the positive and negative leads of the heating wire 111, allowing the positive and negative leads of the heating wire 111 to pass through, so that the positive lead of the heating wire 111 can be connected to the second electrode 14, and the negative lead of the heating wire 111 can be connected to the long hanging angle 133. The fixing hole 161, positioning hole 162, and lead hole 163 of the sealing oil component 16 are all through holes.

[0033] In other embodiments, the sealing element 16 may also be provided with a connection hole corresponding to the second electrode 14, and the positive electrode pin of the heating wire 111 and the second electrode 14 may be connected in the connection hole by interference fit.

[0034] In the above embodiment, the second electrode 14 and the negative electrode pin are made of metal, preferably copper or a copper alloy, but other suitable materials such as graphite, steel, cast iron, and tungsten alloy can also be used. The bottom cover 12 is preferably made of plastic, but can also be made of hard materials such as resin, as long as it has a certain hardness at room temperature and is not easily deformed. The oil sealing component 16 can be made of silicone, rubber, plastic, or other suitable materials, without specific limitations.

[0035] In the above embodiments, the electronic atomizing bullet may also include conventional structures such as an oil storage component, oil-guiding cotton, and air inlet and outlet channels, which will not be described in detail here. Any related structure in the prior art can be used.

[0036] The electronic atomizing cartridge in this application can be an electronic cigarette cartridge or a component in other electronic atomizers.

[0037] In summary, unlike existing technologies, this application provides a bottom cap assembly for an electronic atomizer. The motor pins of the heating wire are connected to electrodes set on the bottom cap, thereby avoiding the use of wires. Furthermore, the bottom cap can provide certain support to prevent pin deformation, thus maintaining a good flavor output.

[0038] This application also provides an electronic atomizer, which includes a power module and an electronic atomizing cartridge connected to each other, the electronic atomizing cartridge being the aforementioned type. Since the electronic atomizing cartridge can be an electronic cigarette cartridge, the electronic atomizer of this application can be an electronic cigarette.
