Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0030] In one embodiment, Figures 1 to 3As shown, an embodiment of the present application provides an electronic atomizer device 1, which may specifically include a shell assembly 100, an atomizer assembly 200 and a PCBA assembly 300. Among them, the shell assembly 100 may specifically include an inner shell 110, an outer shell 120 and a base 130, the inner shell 110 has an air flow channel 111 and a liquid storage chamber 112 connected to the air flow channel 111, and the inner shell 110 is built into the installation cavity formed by the outer shell 120 and the base 130. The atomizer assembly 200 can be specifically installed in the installation cavity and partially extend into the air flow channel 111 to be in liquid communication with the liquid storage chamber 112 to heat the liquid in the liquid storage chamber 112 and atomize it to form an aerosol. The atomizer assembly 200 is also recessed on the side surface facing the base 130 to form at least one first electrical connection groove 21. The PCBA assembly 300 can be specifically installed on the base 130, and at least one first electrical connection protrusion 310 is formed on the surface of the side away from the base 130. The at least one first electrical connection protrusion 310 is plugged into and connected to the at least one first electrical connection groove 21 in a one-to-one correspondence to achieve electrical connection between the PCBA assembly 300 and the atomizer assembly 200.

[0031] It is understandable that the electronic atomization device 1 mentioned in the embodiment of the present application is mainly used for the atomization operation of a specific liquid, so as to convert the stored specific liquid (specifically, it can be an atomized liquid such as tobacco oil) into an aerosol and spray it out for the user to inhale and use. The part of the atomization component 200 mentioned above that extends into the air flow channel 111 to be connected to the liquid of the liquid storage chamber 112 specifically refers to the liquid outlet where the liquid storage chamber 112 is connected to the air flow channel 111, which corresponds to the part of the atomization component 200 extending into the air flow channel 111, so that the liquid in the liquid storage chamber 112 can flow through the liquid outlet to the part of the atomization component 200 extending into the air flow channel 111, so that the part of the atomization component 200 extending into the air flow channel 111 remains moist or semi-moist. Such a setting can avoid the problem of delayed liquid outflow of part of the product when the product is first used, which affects the atomization effect of the atomization component 200. In addition, in order to facilitate the user's use of the electronic atomizer device for suction, the end of the above-mentioned shell 120 away from the base 130 also has a suction nozzle 121 that can be connected to the air flow channel 111, and the connection between the suction nozzle 121 and the rest of the shell 120 is achieved through a curved surface, so as to effectively improve the user's suction experience. Furthermore, the end face of the suction nozzle 121 is concavely provided with an arc-shaped groove body, and the bottom of the groove of the arc-shaped groove body is provided with an air vent, and the air vent is connected to the air flow channel 111. In this way, the air vent can be provided at the bottom of the groove of the arc-shaped groove body to effectively optimize the flow mode of the aerosol near the air vent, so as to provide the user with a softer and more comfortable suction taste. In addition, the aforementioned PCBA assembly 300 may specifically include a PCBA mainboard that implements overall functional control of the electronic atomization device 1. A control button is provided on the side of the PCBA mainboard facing the base 130. The control button passes through the base 130 and is exposed on the outer surface of the base 130, allowing the user to control the electronic atomization device 1 to perform functions such as turning it on and off through the control button. The aforementioned first electrical connection protrusion 310 may specifically be a copper column structure fixedly mounted on the side of the PCBA mainboard away from the base 130, or other metal column structure that can achieve electrical connection.

[0032] In this way, the electronic atomization device 1 provided in the embodiment of the present application, through the above-mentioned structural arrangement, can achieve electrical connection between the PCBA assembly 300 and the atomization assembly 200 by simply plugging and connecting at least one first electrical connection protrusion 310 formed on the side surface of the PCBA assembly 300 away from the base 130 with at least one first electrical connection groove 21 formed on the side surface of the atomization assembly 200 facing the base 130. In this way, the entire assembly process does not require the use of cumbersome welding processes, which not only effectively simplifies the entire assembly process steps of the electronic atomization device 1 and improves its production efficiency, but also greatly reduces the production cost of the electronic atomization device 1.

[0033] In some examples, such as Figure 2 and Figure 3 As shown, the atomizer assembly 200 may specifically include an atomizer core module 210 and a first module bracket 220. An airflow inlet (not shown) is provided at one end of the airflow channel 111 adjacent to the first module bracket 220. The atomizer core module 210 is mounted on the side of the first module bracket 220 away from the base 130 and extends from the airflow inlet into the airflow channel 111. The surface of the first module bracket 220 facing the base 130 is recessed with at least one first groove, and the bottom wall of each first groove is fixed with a pin of the atomizer core module 210 to form a corresponding first electrical connection groove 21. In this way, through the above-mentioned structural setting, when each first electrical connection protrusion 310 on the PCBA assembly 300 is plugged into the corresponding first electrical connection groove 21, each first electrical connection protrusion 310 is correspondingly abutted on a pin of the atomizer core module 210 to perform corresponding abutment communication, thereby ultimately achieving electrical connection between the PCBA assembly 300 and the atomizer assembly 200.

[0034] It can be understood that the atomizer core module 210 mentioned in this example may specifically include an atomizer core with a liquid guiding function and a heating wire wrapped around the atomizer core. The heating wire heats the liquid in the atomizer core and atomizes it to form a corresponding aerosol. Generally speaking, the heating wire can lead out three pins to be electrically connected to the PCBA component 300, so the number of the first electrical connection groove 21 and the first electrical connection protrusion 310 mentioned above can be specifically set to three.

[0035] In some examples, such as Figure 2 and Figure 3As shown, a first pin puncture hole 22 is provided through the surface of the first module support 220 on the side facing the base 130. Each pin of the atomizer core module 210 extends through the first pin puncture hole 22 to the side of the first module support 220 facing the base 130, and then bends through the opening of the corresponding first trough body to extend to the bottom wall of the corresponding first trough body for fixation, thereby forming a corresponding first electrical connection groove 21. In this way, the structural arrangement of the first pin puncture hole 22 allows the airflow channel 111 located on the side of the first module support 220 away from the base 130 to be connected to the side of the first module support 220 facing the base 130. On the other hand, the pins of the atomizer core module 210 installed on the side of the first module support 220 away from the base 130 can extend through the first module support 220 to the side of the first module support 220 facing the base 130, and be installed and fixed on the bottom wall of the corresponding first slot body recessed on the surface of the first module support 220 facing the base 130, thereby forming a corresponding first electrical connection groove 21. For those skilled in the art, the following structure can also be used to form the corresponding first electrical connection groove 21, that is, the peripheral inner wall of each first slot body is connected to the peripheral inner wall of the first pin puncture hole 22, so that each pin of the atomizer core module 210 can extend through the first pin puncture hole 22 to the bottom wall of the corresponding first slot body for fixation, thereby forming a corresponding first electrical connection groove 21.

[0036] In some examples, such as Figure 2 and Figure 3As shown, a second groove is provided on the side of the first module bracket 220 facing the base 130. The opening of the first pin puncture hole 22 and the notch of the at least one first electrical connection groove 21 are both located on the bottom wall of the second groove. The atomizer assembly 200 also includes a first airway bracket 230, a second airway bracket 240, and an air regulating switch 250. The first airway bracket 230 is provided with a first air inlet hole 231 extending therethrough and is installed between the PCBA assembly 300 and the base 130. The base 130 is provided with a second air inlet hole 131 correspondingly connected to the first air inlet hole 231. The air regulating switch 250 is installed between the first and second air inlet holes 231, 131, to adjust the opening size of the first and second air inlet holes 231, 131. The second airway bracket 240 covers the notch of the second groove to form an air inlet cavity. A plug-in portion 242 with an air inlet channel 241 is protruding from the side of the second air duct support 240 facing the PCBA assembly 300. The plug-in portion 242 penetrates the PCBA assembly 300 to connect with the first air inlet hole 231. The second air duct support 240 is also provided with at least one escape hole 243 extending therethrough. Each escape hole 243 corresponds to at least one first electrical connection protrusion 310, allowing each first electrical connection protrusion 310 to connect with the corresponding first electrical connection groove 21 through the corresponding escape hole 243. In this way, through the above-mentioned structural setting, the air inlet of the air flow channel 111 can be connected to the outside world in sequence through the first pin puncture hole 22, the air inlet cavity, the air inlet channel 241, the first air inlet hole 231 and the second air inlet hole 131 to carry out corresponding air intake. At the same time, by setting an air adjustment switch 250 between the first air inlet hole 231 and the second air inlet hole 131 to adjust the opening size of the first air inlet hole 231 and the second air inlet hole 131, the air intake amount entering the air flow channel 111 can be adjusted, thereby meeting the needs of different users for different puffing tastes, thereby improving the user's puffing experience. In addition, the setting of the air inlet cavity can also temporarily buffer the liquid seeping out of the air flow channel 111 to avoid leakage. Furthermore, the atomizer assembly 200 also includes a bracket absorbent cotton 260, which is arranged in the air inlet cavity and surrounds the opening of the first pin puncture hole 22 and the notch of at least one first electrical connection groove 21. In this way, the arrangement of the bracket absorbent cotton 260 can further ensure that the liquid that penetrates into the air inlet cavity will only be temporarily buffered in the air inlet cavity and will not flow out through the air inlet channel 241, thereby effectively avoiding leakage.

[0037] In some examples, such as Figure 2 and Figure 3As shown, the electronic atomization device 1 also includes a power supply assembly 400, which is installed in the installation cavity and has at least one second electrical connection groove 41 formed on the side surface facing the base 130. The PCBA assembly 300 also has at least one second electrical connection protrusion 320 formed on the side surface away from the base 130, and the at least one second electrical connection protrusion 320 is plugged and connected with the at least one second electrical connection groove 41 in a one-to-one correspondence to achieve electrical connection between the PCBA assembly 300 and the power supply assembly 400. In this way, through the above-mentioned structural setting, during the process of assembling the power supply assembly 400 and the PCBA assembly 300, it is only necessary to plug and connect the at least one second electrical connection protrusion 320 formed on the side surface of the PCBA assembly 300 away from the base 130 with the at least one second electrical connection groove 41 formed on the side surface of the power supply assembly 400 facing the base 130 in a one-to-one correspondence. Likewise, the entire assembly process does not require complicated welding processes, which not only effectively simplifies the entire assembly process steps of the electronic atomization device 1 and improves its production efficiency, but also greatly reduces the production cost of the electronic atomization device 1.

[0038] In some examples, such as Figure 2 and Figure 3 As shown, the power supply assembly 400 includes a battery module 410 and a second module bracket 420. The battery module 410 is mounted on a side of the second module bracket 420 away from the base 130. The side of the second module bracket 420 facing the base 130 is recessed with at least one third groove, and the bottom wall of each third groove is fixed with a pin of the battery module 410, forming a corresponding second electrical connection groove 41. Thus, through this structural arrangement, when each second electrical connection protrusion 320 on the PCBA assembly 300 is plugged into the corresponding second electrical connection groove 41, each second electrical connection protrusion 320 abuts against a pin of the battery module 410, achieving corresponding abutment and communication, ultimately achieving electrical connection between the PCBA assembly 300 and the power supply assembly 400.

[0039] It is understood that the second module support 420 mentioned in this example and the first module support 220 mentioned above can be designed separately or as an integrated structure, so that the first module support 220 mentioned above also serves as the second module support 420 in this example. The battery module 410 in this example can be specifically formed by packaging a conventional battery, with two electrical connection wires extending from each end of the battery. The end of each electrical connection wire is stripped and tinned to form a pin of the battery module 410. Generally speaking, the battery module 410 can extend two pins for electrical connection to the PCBA assembly 300, so the number of the second electrical connection groove 41 and the second electrical connection protrusion 320 mentioned above can be specifically set to two. In addition, the second module support 420 mentioned in this example, as well as the first module support 220, the first airway support 230, and the second airway support 240 mentioned above, are all made of silicone, which facilitates the corresponding hollowing and hole design and ensures the sealing performance of the corresponding structure.

[0040] In some examples, such as Figure 2 and Figure 3 As shown, a second pin puncture hole (not shown) is provided through the surface of the second module support 420 facing the base 130. Each pin of the battery module 410 extends through the second pin puncture hole to the side of the second module support 420 facing the base 130, and is bent through the opening of the corresponding third trough body to extend to the bottom wall of the corresponding third trough body for fixation, thereby forming a corresponding second electrical connection groove 41. In this way, through the structural arrangement of the above-mentioned second pin puncture hole, the pins of the battery module 410 installed on the side of the second module support 420 away from the base 130 can pass through the second module support 420 and extend to the side of the second module support 420 facing the base 130, so as to be installed and fixed on the bottom wall of the corresponding third trough body recessed on the surface of the second module support 420 facing the base 130, thereby forming a corresponding second electrical connection groove 41. For those skilled in the art, the following structure can also be used to form the corresponding second electrical connection groove 41, that is, the inner wall of the circumferential side of each third groove body is connected to the inner wall of the circumferential side of the second pin puncture hole, so that each pin of the battery module 410 can extend through the second pin puncture hole to the bottom wall of the corresponding third groove body for fixation, so as to form corresponding second electrical connection grooves 41 respectively.

[0041] The above description is only a preferred embodiment of the present application and does not limit the patent scope of the present application. All equivalent structural transformations made by using the contents of the present application specification and drawings under the utility model concept of the present application, or direct / indirect application in other related technical fields are included in the patent protection scope of the present application.
