[0033] The electronic atomization device generally includes a battery assembly and an atomizer. The battery assembly is used to power the atomizer, and the atomizer is used to heat the atomization medium and atomize it to form an aerosol after power is turned on. The battery assembly generally includes components such as a battery, a circuit board, a ejector pin, and an airflow sensor. The battery is electrically connected to the circuit board, and the ejector pin is electrically connected to the circuit board. The ejector pin is used to form an electrical connection with the atomizer to power the atomizer. The airflow sensor is electrically connected to the circuit board. The airflow sensor is used to detect the airflow when the user draws on the electronic atomization device and feed it back to the circuit board, and the circuit board starts to power the atomizer. One of the common airflow sensors is the microphone.

[0034] At present, due to the limitations of the internal layout of the battery assembly, the circuit board, the airflow sensor and the ejector pin are all arranged separately. The electrical connection between the circuit board and the ejector pin is formed by a wire, and the electrical connection between the circuit board and the airflow sensor is formed by a wire. However, the wire welding process is complicated and cannot be automated. Manual welding is required, so cold welding is prone to occur, resulting in poor connection, high labor costs, and reduced production efficiency.

[0035] In order to solve the above problems, the embodiment of the present application provides a battery assembly 100 and an electronic atomization device. By arranging the airflow sensor 130 and the first electrical connector 140 on the circuit board 120 and electrically connecting them to the circuit board 120, there is no need to weld wires between the circuit board 120 and the airflow sensor 130, nor is there any need to weld wires between the circuit board 120 and the first electrical connector 140, thereby reducing the problem of cold solder joints caused by manual welding of wires, reducing quality problems and welding costs caused by manual welding, and also improving the production efficiency of the entire battery assembly 100.

[0036] See also Figure 1 and Figure 2 The embodiment of the present application provides an electronic atomization device, including an atomizer 200 and a battery assembly 100. The battery assembly 100 is mechanically connected to the atomizer 200, and the battery assembly 100 is electrically connected to the atomizer 200. The battery assembly 100 is used to power the atomizer 200. The atomizer 200 is used to atomize the atomization medium into aerosol particles and transport the generated aerosol particles to the oral cavity of the smoker.

[0037] Please also read Figures 2 to 7 , the battery assembly 100 provided in the embodiment of the present application is now described.

[0038] The battery assembly 100 includes a battery 110, a circuit board 120, an airflow sensor 130 and a first electrical connector 140. The circuit board 120 is electrically connected to the battery 110. The airflow sensor 130 and the first electrical connector 140 are respectively arranged on the circuit board 120. The airflow sensor 130 and the first electrical connector 140 are respectively directly electrically connected to the circuit board 120. The first electrical connector 140 is used to be electrically connected to the atomizer 200.

[0039] The battery 110 is electrically connected to the circuit board 120, the circuit board 120 is electrically connected to the first electrical connector 140, and the first electrical connector 140 is electrically connected to the atomizer 200, so that the atomizer 200 can be powered by the battery 110, so that the atomizer 200 heats the atomizing medium and atomizes it to form an aerosol.

[0040] The airflow sensor 130 is electrically connected to the circuit board 120 . When the user draws air from the atomizer 200 , the airflow sensor 130 detects airflow changes and feeds back to the circuit board 120 . The circuit board 120 starts to power the atomizer 200 through the first electrical connector 140 , thereby starting the atomizer 200 .

[0041] The battery assembly 100 provided in the embodiment of the present application, by arranging both the airflow sensor 130 and the first electrical connector 140 on the circuit board 120, enables the airflow sensor 130 to be directly electrically connected to the circuit board 120, without the need to realize the electrical connection between the airflow sensor 130 and the circuit board 120 by welding a wire between the airflow sensor 130 and the circuit board 120; at the same time, the first electrical connector 140 can be directly electrically connected to the circuit board 120, without the need to realize the electrical connection between the first electrical connector 140 and the circuit board 120 by welding a wire between the first electrical connector 140 and the circuit board 120. In general, the design of integrating the airflow sensor 130 and the first electrical connector 140 on the circuit board 120 of the present application not only reduces the material cost of the wire and the labor cost of welding the wire, but also improves the electrical connection stability between the airflow sensor 130 and the first electrical connector 140 and the circuit board 120, and also improves the assembly efficiency of the battery assembly 100.

[0042] In one embodiment, please refer to Figure 2 , Figure 3 , Figure 5 and Figure 6The circuit board 120 is also provided with a charging base 150, which is electrically connected to the circuit board 120. The charging base 150 is used to form an electrical connection with an external power source to charge the battery 110. In addition, the charging base 150 can be connected to an external electrical device through a data line to transmit information of the external electrical device to the circuit board 120. In this embodiment, by integrating the charging base 150 on the circuit board 120, there is no need to connect a wire between the charging base 150 and the circuit board 120, thereby reducing the wire welding process, reducing costs and improving assembly efficiency.

[0043] In one embodiment, see Figure 3 and Figure 6 , the airflow sensor 130 is mounted on the circuit board 120 in a patch manner, that is, the airflow sensor 130 is mounted on the circuit board 120 in an SMT patch manner to form an electrical connection with the circuit board 120, and the patch of the airflow sensor 130 can be automatically patched by an automatic device, thereby improving the assembly efficiency of the airflow sensor 130. It can be understood that in other embodiments of the present application, the airflow sensor 130 can also be installed on the circuit board 120 in a plug-in manner, which is not the only limitation here.

[0044] In one embodiment, see Figure 3 and Figure 6 , the first electrical connector 140 is mounted on the circuit board 120 in a patch manner, that is, the first electrical connector 140 is mounted on the circuit board 120 in an SMT patch manner to form an electrical connection with the circuit board 120, and the patch of the first electrical connector 140 can be automatically mounted by an automatic device, thereby improving the assembly efficiency of the first electrical connector 140. It can be understood that in other embodiments of the present application, the first electrical connector 140 can also be installed on the circuit board 120 in a plug-in manner, which is not the only limitation here.

[0045] In one embodiment, see Figure 3 and Figure 6, the charging stand 150 is installed on the circuit board 120 in the form of a patch, that is, the charging stand 150 is installed on the circuit board 120 in the form of an SMT patch to form an electrical connection with the circuit board 120, and the patch of the charging stand 150 can be automatically patched by automatic equipment, thereby improving the assembly efficiency of the charging stand 150. In addition, in order to improve the installation reliability of the charging stand 150 on the circuit board 120, a plug-in structure can also be provided between the charging stand 150 and the circuit board 120, for example, a plug-in block is provided on the charging stand 150, a slot is provided on the circuit board 120, and the plug-in block is inserted into the slot to realize the installation and positioning of the charging stand 150 on the circuit board 120. It can be understood that in other embodiments of the present application, the charging stand 150 can also be installed on the circuit board 120 by plugging, which is not the only limitation here.

[0046] In one embodiment, see Figure 3 The battery assembly 100 further includes a housing 160, and the circuit board 120 is installed in the inner cavity of the housing 160 and is arranged close to the atomizer 200. By arranging the circuit board 120 close to the atomizer 200, the first electrical connector 140 can be directly extended to be electrically connected to the atomizer 200, without setting a wire between the first electrical connector 140 and the atomizer 200 for connection, or it can also avoid setting the length of the first electrical connector 140 to be very long, thereby reducing the connection stability of the first electrical connector 140.

[0047] In one embodiment, see Figure 3 , the circuit board 120 is arranged in the housing 160 along the longitudinal direction. The longitudinal direction refers to a direction parallel or substantially parallel to the vertical direction when the electronic atomization device is placed vertically. In this embodiment, the circuit board 120 is arranged along the longitudinal direction, so that the first electrical connector 140, the airflow sensor 130 and the charging seat 150 can be installed at different longitudinal positions of the circuit board 120, and then the first electrical connector 140, the airflow sensor 130 and the charging seat 150 can be installed at different longitudinal positions in the atomizer 200, which is convenient for the layout of the first electrical connector 140, the airflow sensor 130 and the charging seat 150, and also convenient for the first electrical connector 140 to form an electrical connection with the atomizer 200, and convenient for the charging seat 150 to form an electrical connection with the external power supply.

[0048] In one embodiment, see Figure 3 , Figure 6 and Figure 7The airflow sensor 130, the charging seat 150 and the first electrical connector 140 are respectively arranged on opposite sides of the circuit board 120, and the first electrical connector 140, the airflow sensor 130 and the charging seat 150 are sequentially distributed along the longitudinal direction. In this way, the first electrical connector 140, the airflow sensor 130 and the charging seat 150 can be staggered with each other on the circuit board 120 to avoid structural interference between the three structures. At the same time, the first electrical connector 140 is as close to the atomizer 200 as possible to form an electrical connection with the atomizer 200, and the charging seat 150 is set at a position that is convenient for plugging.

[0049] In a specific embodiment, see Figure 3 The circuit board 120 has a first side 124 and a second side 125 that are arranged opposite to each other, the first electrical connector 140 is arranged on the first side 124, the airflow sensor 130 and the charging seat 150 are arranged on the second side 125, and the first electrical connector 140 is arranged at the top of the circuit board 120, and extends upward from the top of the circuit board 120 to be electrically connected to the atomizer 200. The first electrical connector 140, the airflow sensor 130 and the charging seat 150 are arranged in sequence along the longitudinal direction, that is, the charging seat 150 is arranged at a position as close to the bottom as possible on the circuit board 120, so that the charging port 163 of the housing 160 corresponding to the charging seat 150 is also arranged as close to the bottom as possible, thereby reducing the impact of the charging port 163 and the charging seat 150 on the appearance of the entire electronic atomization device. It can be understood that in other embodiments of the present application, the positions of the airflow sensor 130 and the charging seat 150 can also be interchanged. In addition, the airflow sensor 130 can also be arranged on the first side 124, or the charging seat 150 is arranged on the first side 124, which is not limited here.

[0050] In one embodiment, see Figure 1 and Figure 3 A charging port 163 is provided on the side wall of the outer shell 160 at a position corresponding to the charging seat 150, and an external power cord can be inserted into the charging seat 150 via the charging port 163 to achieve electrical connection between the external power source and the atomizer 200. Among them, by connecting the charging seat 150 to the external power source from the side, it is not necessary to set a charging plate at the bottom of the outer shell 160. The charging seat 150 is installed on the charging plate, and then the circuit board 120 and the charging plate are welded by wires. It can be understood that in other embodiments of the present application, when the space of the battery assembly 100 allows, the circuit board 120 can also be extended longitudinally to the bottom of the outer shell 160, and then the charging seat 150 is installed on the circuit board 120, and the charging port 163 is formed at the bottom of the outer shell 160, which is not the only limitation here.

[0051] In one embodiment, see Figure 5 and Figure 7The first electrical connector 140 is a spring-type connector, which is mounted on the circuit board 120 by means of a patch. The spring-type connector is a common standard connector, which is simple to patch and can be patched in batches by automated equipment, with high patch efficiency and low structural cost.

[0052] In one embodiment, see Figure 7 The first electrical connector 140 is provided with a patch portion 141, which is used to be patched on the circuit board 120. The first electrical connector 140 is also provided with a plug portion 142, and the circuit board 120 is provided with a plug hole 121, and the plug portion 142 is inserted into the plug hole 121, so as to realize the positioning of the first electrical connector 140 on the circuit board 120, and also ensure the reliability of the installation of the first electrical connector 140 on the circuit board 120. In addition, the first electrical connector 140 also includes an elastic portion 143, which is used to elastically abut against the atomizer 200 to form an electrical connection between the circuit board 120 and the atomizer 200.

[0053] It is understandable that in other embodiments of the present application, the first electrical connector 140 may also be other elastic conductive members, as long as the first electrical connector 140 can be mounted on the circuit board 120 by means of a patch and can form an elastic abutment with the atomizer 200.

[0054] In another embodiment of the present application, see Figure 5 The battery assembly 100 further includes a conductive spring 170, which is mounted on the housing 160. The first electrical connector 140 elastically contacts the conductive spring 170, and the conductive spring 170 is used to elastically contact the atomizer 200. The conductive spring 170 has a regular shape, which facilitates the sealing connection between the conductive spring 170 and the housing 160, thereby preventing the atomized medium in the atomizer 200 from entering the interior of the housing 160 through the gap between the conductive spring 170 and the housing 160.

[0055] Specifically, a through mounting hole is formed on the top of the housing 160 , and the conductive elastic column 170 is interference-fitted with the mounting hole, so that the conductive elastic column 170 is sealed and mounted on the housing 160 .

[0056] In this embodiment, a conductive spring column 170 is provided between the spring type connector and the atomizer 200 to avoid the problem that the spring type connector is irregular in shape. However, the spring type connector needs to penetrate the top of the shell 160 to form an electrical connection with the atomizer 200, which makes it difficult for the spring type connector to form a sealed connection with the shell 160.

[0057] In one embodiment, see Figure 3 and Figure 7, a vent 122 is provided on the circuit board 120, one end of the vent 122 is connected to the air flow channel of the atomizer 200, and the air flow sensor 130 is covered outside the other end of the vent 122. When the smoker draws air from the atomizer 200, air flows in the air flow channel, and part of the air flows through the air flow sensor 130 from the vent 122 to be detected by the air flow sensor 130, and then fed back to the circuit board 120. In this embodiment, since the air flow sensor 130 needs to be attached to the circuit board 120, the provision of the vent 122 on the circuit board 120 can ensure that the air flow sensor 130 can detect the air flow. In addition, an air flow sensor seat can also be installed outside the air flow sensor 130 to ensure the installation reliability of the air flow sensor 130 on the circuit board 120.

[0058] In one embodiment, an air inlet 164 is formed at the bottom of the housing 160, and a mounting cavity is formed on the housing 160, in which the battery 110, the circuit board 120, the air flow sensor 130, the first electrical connector 140 and the charging stand 150 are all mounted. An air outlet is formed at the top of the housing 160, and the air outlet is connected to the air flow channel of the atomizer 200, that is, the vent 122 is connected to the air flow channel through the mounting cavity and the air outlet. When the user inhales the atomizer 200, the external airflow enters the mounting cavity through the air inlet 164, and enters the vent 122 through the mounting cavity to be detected by the air flow sensor 130 to start the atomizer 200, and at the same time, the external airflow enters the air flow channel of the atomizer 200 through the air outlet to take away the aerosol formed by the heating and atomization of the atomizer 200 for the user to inhale.

[0059] In one embodiment, see Figure 5 and Figure 8 A support portion 1611 and a hook 1612 are formed on the inner wall of the housing 160. The support portion 1611 is used to abut against the second side 125 of the circuit board 120, and the hook 1612 is used to hook the edge of the first side 124 of the circuit board 120, so that the circuit board 120 can be positioned in the lateral direction by the support portion 1611 and the hook 1612.

[0060] See also Figure 5 and Figure 8 The inner wall of the housing 160 is also formed with a positioning portion 1613 , and the edge of the circuit board 120 is formed with a positioning groove 123 . The positioning portion 1613 is plugged into and matched with the positioning groove 123 to form a longitudinal positioning of the circuit board 120 in the housing 160 .

[0061] In one embodiment, see Figure 4The housing 160 is generally cylindrical, and includes a first section 166 and a second section 167 connected to each other. A partition 165 is connected to the connection between the first section 166 and the second section 167, and a conductive elastic column 170 is arranged through the partition 165. The first section 166 is cylindrical, and the first section 166 is used to be sleeved on the outside of the atomizer 200 to form a connection with the atomizer 200. The second section 167 is cylindrical, and the second section 167 is used to install the circuit board 120 and the battery 110. The circuit board 120 and the battery 110 are arranged at intervals in the longitudinal direction. The first electrical connector 140, the charging seat 150 and the airflow sensor 130 are all installed on the circuit board 120.

[0062] See also Figure 2 The housing 160 includes a main housing 161 and a battery cover 162. The main housing 161 has a bottom and a top. The portion of the main housing 161 corresponding to the circuit board 120 and the battery 110 is in a semicircular arc shape, that is, the second section 167 of the main housing 161 is in a semicircular arc shape, and the battery cover 162 is in a semicircular arc shape. The battery cover 162 and the second section 167 are buckled relative to each other to form a cylindrical structure.
