Abstract
Description
Technical Field
[0001] The present application relates to the field of atomization technology, and in particular provides a base, an atomizer, and an electronic atomization device. Background Art
[0002] Currently, atomizers on the market typically have a base for connecting the electrodes. Conventional technology often uses interference riveting to assemble the electrodes and base. This has the disadvantage of a loose connection between the electrodes and the base. The intermittent high and low temperature operation of the atomizer causes the plastic base to expand and contract. Over time, gaps form between the base and the electrodes, compromising the seal and causing leakage. Furthermore, during interference riveting, the base is subjected to local stress, often resulting in a certain percentage of fractures, which can affect the product. Utility Model Content

[0006] The beneficial effects of this application are that, by integrally molding the substrate and electrode body within an injection mold, the substrate and electrode body are tightly connected and firmly bonded, resulting in good structural integrity. A gap is less likely to form between the substrate and electrode body, effectively ensuring a waterproof seal between the electrode body and the substrate, thereby improving product reliability. Furthermore, the use of injection molding to combine the substrate and electrode body increases the assembly success rate and production efficiency, and also prevents damage to the substrate structure during assembly, thereby improving product yield.

[0010] By adopting the above technical solution, the connection stability and waterproofness between the electrode body and the base body are further improved through the cooperation between the convex edge and the embedded groove.
[0011] In some embodiments, there is a gap between the location of the embedding groove and two opposite ends of the connecting hole in the axial direction.
[0012] By adopting the above technical solution, the base can effectively limit the ring body in the upper and lower directions, effectively restricting the ring body from detaching from the connecting hole, and the connection between the ring body and the base is firm.

[0015] In some embodiments, the electrical connector has an electrical contact surface, and the electrical contact surface is exposed from the base.
[0016] By adopting the above technical solution, the power supply component of the electronic atomization device is in contact with the electrical contact surface to achieve electrical conduction with the electrode connector.
[0017] In some embodiments, the base body has a base surface, and the electrical contact surface coincides with the base surface.
[0018] By adopting the above technical solution, the electrical contact surface coincides with the base surface, which facilitates the abutment contact between the external power supply component and the electrical contact surface.

[0041] Atomizers typically have a base for connecting electrodes. Conventional assemblies often utilize interference riveting to achieve assembly. This disadvantage is a loose connection between the electrodes and the base. The intermittent high and low temperature transitions experienced by the atomizer cause the plastic base to expand and contract. Over extended use, gaps form between the base and the electrodes, compromising sealing and causing leakage. Furthermore, during interference riveting, localized stress on the base can lead to fractures, potentially compromising the product.
[0042] Based on this, and to address the above issues, this application has designed a base. By integrally molding the base and electrode body within an injection mold, the base and electrode body are tightly connected and firmly bonded, resulting in good structural integrity. This reduces the likelihood of gaps forming between the base and electrode body, effectively ensuring a waterproof seal between the electrode body and the base, and improving product reliability. Furthermore, the use of injection molding to combine the base and electrode body undoubtedly increases the assembly success rate and production efficiency. It also avoids damage to the base structure during assembly, improving product yield.

[0045] refer to Figure 1 、 Figure 5 In some embodiments, the atomizer 100 includes a main body 101 and a base 1 disposed at the bottom of the main body 101 , wherein the base 1 includes an electrode body 2 . The battery module 2002 is configured to be electrically connected to the electrode body 2 .
[0046] Specifically, the atomizer 100 also includes an atomizer core (not shown) disposed within the main body 101. The battery module 2002 is connected to the electrode body 2 and is used to power the atomizer core. The main body 101 stores an aerosol matrix. When the atomizer core is powered, it heats and atomizes the aerosol matrix to generate atomized gas for the user to inhale.
[0047] The electronic atomization device 1000 of the present application may be a device with a replaceable atomizer 100, i.e., the atomizer 100 and the power supply assembly 200 are detachably connected. Alternatively, the electronic atomization device 1000 of the present application may be a disposable electronic atomization device 1000, i.e., the atomizer 100 and the power supply assembly 200 are not detachably connected. This is not specifically limited here, as long as the power supply assembly 200 can supply power to the atomizer core.

[0049] Specifically, the base 3 is an injection molded part; the electrode body 2 is a solid conductive material, preferably a metal; in the embodiment of the present application, an injection mold for the base 3 is pre-made according to the structural dimensions of the base 3, the electrode body 2 is arranged in the injection mold, and the injection mold is injection molded using an injection molding machine to produce the base 3; then, after the base 3 is injection molded, the base 3 will be injection molded together with the electrode body 2, and the two form an integrated structure, which is tightly combined and firmly connected, and has good structural integrity.
[0050] It can be understood that the number of electrode bodies 2 is at least two, which can form at least one positive electrode and one negative electrode electrically connected to the battery module 2002; the electrode body 2 is at least partially exposed outside the base 3, which facilitates the electrical connection between the electrode body 2, the battery module 2002 and the atomizer core.
[0051] refer to Figure 2 、 Figure 3 In the circumferential direction of the electrode body 2, the substrate 3 is sealed and connected to the electrode body 2; then the electrode body 2 is surrounded by the substrate 3, which effectively ensures the waterproof sealing between the electrode body 2 and the substrate 3 and improves product reliability.
[0052] The base 1 of the present application is achieved by integrally injection molding the base 3 and the electrode body 2 in an injection mold, so that the base 3 and the electrode body 2 are tightly connected and firmly combined, the structural integrity is good, and it is difficult to produce a gap between the base 3 and the electrode body 2, effectively ensuring the waterproof sealing between the electrode body 2 and the base 3, and improving product reliability.
[0053] The combination of the base body 3 and the electrode body 2 is achieved by injection molding in a mold. Compared with the method of assembling the base body 3 and the electrode body 2 by interference riveting in the prior art, in addition to making the base body 3 and the electrode body 2 tightly combined, the assembly success rate is undoubtedly higher and the production efficiency is higher; it can also avoid damage to the structure of the base body 3 during assembly, thereby improving the product yield.
[0054] refer to Figure 1-Figure 3 In some embodiments, the electrode body 2 includes a ring body 201 and a pin 202 provided on the ring body 201 , and the base 3 is formed with a connecting hole 4 for accommodating the ring body 201 , and the outer wall of the ring body 201 is connected to the inner wall of the base 3 at the connecting hole 4 .
[0055] Specifically, the electrode body 2 includes a circular ring body 201 and a thimble 202. The ring body 201 is used to combine with the base body 3 to improve the combination stability; the thimble 202 protrudes upward relative to the ring body 201 and is used to electrically connect with the atomizer core.
[0056] After the base body 3 and the electrical connector 2 are injection molded together, the inner wall of the base body 3 at the connection hole 4 will be tightly attached to the outer wall of the ring body 201 , and the two are tightly combined. The electrode body 2 has better structural reliability and waterproof sealing in the base body 3 .

[0058] Specifically, the outer wall of the ring body 201 is provided with a circle of protruding edges 5. After the ring body 201 and the base body 3 are injection molded together, a corresponding embedding groove 6 is formed on the inner wall of the connecting hole 4 of the base body 3. The protruding edges 5 are embedded in the embedding groove 6. The cooperation between the protruding edges 5 and the embedding groove 6 further improves the connection stability and waterproofness between the electrode body 2 and the base body 3.
[0059] refer to Figure 4 In some embodiments, there is a gap between the location of the embedding groove 6 and the two opposite ends of the connecting hole 4 in the axial direction.
[0060] It is understood that the embedding groove 6 is formed inside the connecting hole 4 and does not extend to the end of the connecting hole 4. After the protruding edge 5 is embedded in the embedding groove 6, the base 3 can effectively limit the ring body 201 in both the vertical direction, effectively preventing the ring body 201 from separating from the connecting hole 4, and firmly connecting the ring body 201 to the base 3. Preferably, the embedding groove 6 is provided at the middle position along the axial direction inside the connecting hole 4.
[0061] refer to Figure 4 In some embodiments, the depth of the connecting hole 4 is configured to be greater than the thickness of the ring body 201 , and the ring body 201 is accommodated in the connecting hole 4 and does not protrude outside the connecting hole 4 .
[0062] As can be understood, the entire ring body 201 is housed within the connection hole 4, which effectively protects the ring body 201, reduces its contact with the outside air, and increases the product's service life. The ring body 201 does not protrude from the connection hole 4, meaning that the ring body 201 does not interfere with the structure of the base 3 and does not affect the connection between the base 3, the main body 101, and the housing 2001.
[0063] refer to Figure 2 、 Figure 6 In some embodiments, the electrical connector 2 has an electrical contact surface 7 , and the electrical contact surface 7 is exposed from the substrate.
[0064] Specifically, the battery module 2002 has an electrode connector, which may be, but is not limited to, a spring pin, a wire, etc.; the electrode connector is in contact with the electrical contact surface 7 to achieve electrical conduction between the battery module 2002 and the electrode connector 2.
[0065] refer to Figure 2 、 Figure 4 、 Figure 6 In some embodiments, the base body 3 has a base surface 301 , and the electrical contact surface 7 coincides with the base surface 301 .
[0066] It can be understood that in the embodiment of the present application, the atomizer 100 and the battery module 2002 are docked up and down to achieve assembly, the base 3 is located at the bottom of the atomizer 100, the base surface 301 is the horizontal bottom surface of the base 3, and then the base surface 301 faces the battery module 2002; the electrical contact surface 7 coincides with the base surface 301, that is, the electrical contact surface 7 is horizontally facing the battery module 2002, which facilitates electrical connection between the electrical contact surface 7 and the battery module 2002.
[0067] In some embodiments, the battery module 2002 includes a spring pin. After the atomizer 100 and the battery module 2002 are assembled, the top of the spring pin is used to abut against the electrical contact surface 7; the electrical contact surface 7 is horizontally facing the spring pin, and the two can maintain stable abutment, the spring pin conducts smoothly, and ensures stable circuit connection.
[0068] There is no specific limitation on the model of the electronic atomization device 1000 of the present application, that is, the shape of the electronic atomization device can be a wine pot shape, a rectangle, a cylinder, etc.
