[0065] One embodiment of this application provides a battery assembly 1 for an aerosol generating device 10, such as... Figure 12-13 As shown, the assembly includes: a first housing 11, a first support 12, an air guide 15, and a first seal 161. The first housing 11 is provided with an air inlet 113 for air to enter the battery assembly 1. The first support 12 is provided with a first air outlet 123 for air to exit the battery assembly 1. The air guide 15 is connected between the air inlet 113 and the first air outlet 123. The air guide 15 includes a first tube 151, a second tube 152, and an air guide portion 153 located between the first tube 151 and the second tube 152. The first tube 151 is connected to the air inlet 113, and the second tube 152 is connected to the first air outlet 123. The first seal 161 is at least partially housed within the air guide portion 153. The first seal 161 and the air guide portion 153 together define an air guide passage 1531 communicating between the first tube 151 and the second tube 152.

[0066] The battery assembly 1 of this application has an air intake channel defined by the air guide 15 and the first seal 161. The liquid matrix leaked in the aerosol generating device 10 and the condensate in the aerosol will not cause corrosion to the battery 13 and the circuit board in the battery assembly 1.

[0067] In one embodiment of this application, the air guide 153 has an opening at one end, and the first sealing member 161 is disposed at the opening of the air guide 153. The air guide 153 and the first sealing member 161 together form an air guide channel 1531.

[0068] In one embodiment of this application, a first tube 151 defines a first air passage 1511, and a second tube 152 defines a second air passage 1521. The first air passage 1511, the air guide passage 1531, and the second air passage 1521 together form the air intake passage of the battery assembly 1.

[0069] In one embodiment of this application, the air guide 15 is provided with a positioning protrusion 154, and the air guide 15 is positioned on the first housing 11 by the positioning protrusion 154.

[0070] In one embodiment of this application, the air inlet 113 and the first air inlet 123 are not on a straight line. In another embodiment of this application, the first tube 151 and the second tube 152 are offset from each other and therefore not on a straight line.

[0071] In one embodiment of this application, the air guide duct 153 extends in an arc shape between the first tube 151 and the second tube 152, or the air guide duct 153 does not include a straight section, so that the airflow in the air guide duct 1531 is smoother and the airflow is less prone to turbulence. This can prevent the aerosol exhaled by the user from generating a large amount of condensate, and can also reduce airflow noise, lengthen the airway, and limit the condensate from entering the airflow sensor 18.

[0072] In one embodiment of this application, the air duct 1531 extends in an S-shape.

[0073] In one embodiment of this application, the air duct 153 includes a curved groove formed on the first seal 15.

[0074] In one embodiment of this application, the battery assembly 1 includes a circuit board 17 and an airflow sensor 18 held on a first seal 15. The airflow sensor 18 is electrically connected to the circuit board 17 and is located inside the air guide section 153. The airflow sensor 18 is used to sense changes in airflow flowing through the air guide channel 1531.

[0075] In one embodiment of this application, an airflow sensing channel 1611 and a sensing cavity 1612 are further defined between the first seal 161 and the air guide 153. An airflow sensor 18 is disposed in the sensing cavity 1612, and the airflow sensing channel 1611 connects the airflow sensor 18 and the air guide 1531.

[0076] In one embodiment of this application, the connection between the airflow sensing channel 1611 and the air guide channel 1531 is located at the end of the air guide channel 1531 that is closer to the first air hole 123.

[0077] In one embodiment of this application, the cross-sectional area of ​​the inner cavity of the air guide 153 is larger than the cross-sectional area of ​​the inner cavity of the first tube 151 or the second tube 152, thereby restricting the condensate from entering the airflow sensor 18.

[0078] In one embodiment of this application, the battery assembly 1 further includes a second seal 162 located between the air inlet 113 and the first tube 151.

[0079] In one embodiment of this application, the battery assembly 1 further includes a third seal 163 located between the first vent 123 and the second tube 152.

[0080] One embodiment of this application provides an aerosol generating device 10, such as... Figure 1-2 As shown, it includes an atomizer 2 and a battery assembly 1 removably connected to the atomizer 2.

[0081] Battery assembly 1 includes a first housing 11, a first connecting end 102, a battery 13, a first magnetic element 14, and an electrode 120.

The battery assembly 1 and the atomizer 2 are connected by magnetic attraction between the first magnetic element 14 and the second magnetic element 201, with the first central axis 101 and the second central axis 204 collinear. In this application, the first magnetic element 14 and the second magnetic element 201 of the aerosol generating device 10 are magnetically connected by collinearity of the first central axis 101 and the second central axis 203. When the atomizer 2 has multiple liquid storage chambers, the atomizer 2 can rotate relative to the battery assembly 1 around the second central axis 203 to switch between different liquid storage chambers for operation. The battery assembly 1 can be used simultaneously with an atomizer having a single liquid storage chamber or an atomizer with multiple liquid storage chambers.

[0086] In one embodiment of this application, the DC supply voltage provided by battery 13 is in the range of about 2.5V to about 9.0V, and the DC current provided by battery 13 is in the range of about 2.5A to about 20A in amperes. Typically, battery 13 is a rechargeable battery. Alternatively, battery 13 may be another form of charge storage device, such as a capacitor. Battery 13 may require recharging and may have a capacity that allows for storing sufficient energy for one or more pumping operations; for example, battery 13 may have sufficient capacity to allow continuous aerosol generation over a predetermined period of time. In another example, battery 13 may have sufficient capacity to allow the activation of a predetermined number of aerosol generation devices.

[0087] In one embodiment of this application, a groove may be provided on the first support 12 of the battery assembly 1, and a ball may be provided on the atomizer 2.

[0090] In one embodiment of this application, there are multiple first positioning protrusions 121, which are distributed around the first central axis 101. The number of first positioning grooves 202 corresponds to the number of first positioning protrusions 121.

[0091] In one embodiment of this application, there are two first positioning protrusions 121, which are symmetrically distributed about a first central axis 101. In another embodiment of this application, there are two first positioning grooves 202, which are symmetrically distributed about a second central axis 203.

[0092] In one embodiment of this application, when the atomizer 2 is an atomizer with multiple liquid storage chambers, the atomizer 2 and the battery assembly 1 are positioned by the first positioning protrusion 121 and the first positioning groove 202, and the atomizer 2 and the battery assembly 1 can rotate relative to each other to switch between different liquid storage chambers. In this application, when the atomizer 2 is an atomizer with a single liquid storage chamber, the first positioning groove 202 of the atomizer 2 is used to avoid the first positioning protrusion 121 of the battery assembly 1, so that the battery assembly 1 can be adapted to an atomizer with a single liquid storage chamber or an atomizer with multiple liquid storage chambers.

[0093] In one embodiment of this application, the atomizer 2 includes a second housing 21 and a second support 22.

Flavorings contain ingredients that can provide the user with various fragrances or flavors. Vitamin mixtures may be mixtures containing at least one of vitamin A, vitamin B, vitamin C, and vitamin E, but are not limited to these. Based on the different properties of the liquid matrix, aerosol matrix reservoirs can be used in different fields, such as medical and electronic aerosol atomization.

The first connecting end 102 is disposed at one end of the first housing 11 and has a first central axis 101. The first magnetic element 14 is disposed at the first connecting end 102 and its center is located on the first central axis 101. The electrode 120 is disposed at the first connecting end 102 and offset from the first central axis 101. The electrode 120 is used to guide current between the battery 13 and the atomizer 2.

[0110] In one embodiment of this application, the atomizer 2 includes a liquid replenisher 28 and an atomizing device 29, wherein the liquid replenisher 28 can provide a liquid matrix to the atomizing device 29.

[0111] In one embodiment of this application, the replenisher 28 includes a fourth housing 281 and a fifth support 282, the housing 281 and the fifth support 282 defining an upper liquid storage chamber 2811 for storing a liquid matrix, the fifth support 282 including a liquid guide column 2821, the liquid guide column 2821 being hollow and having at least one liquid guide hole 2822.

[0112] In one embodiment of this application, the atomizing device 29 includes a second housing 21 and a sixth support 291, the sixth support 291 being disposed within the second housing 21 and defining a lower liquid storage chamber 2911 for storing a liquid matrix.

[0113] In one embodiment of this application, when the atomizer 2 has a single liquid storage chamber, the liquid storage chamber 211 can be divided into an upper liquid storage chamber 2811 and a lower liquid storage chamber 2911.

[0114] In one embodiment of this application, the liquid guide column 2821 extends into the lower liquid storage chamber 291, and the liquid matrix in the upper liquid storage chamber 2811 can enter the lower liquid storage chamber 2911 through the liquid guide hole 2822.

[0115] In one embodiment of this application, there can be multiple liquid guiding columns 2821, and the number of liquid guiding holes 2822 corresponds to the number of liquid guiding columns 2821. In one embodiment of this application, there are two liquid guiding columns 2821. When the liquid matrix in the liquid guiding hole 2822 of one of the liquid guiding columns 2821 flows out of the upper liquid storage chamber 2811, the air pressure in the upper liquid storage chamber 2811 decreases. At this time, external air can enter the upper liquid storage chamber 2811 through the liquid guiding hole 2822 of the other liquid guiding column 2821, thereby preventing the liquid matrix in the upper liquid storage chamber 2811 from failing to flow out due to the decrease in air pressure.

[0116] In one embodiment of this application, a liquid guiding hole 2822 is disposed on the sidewall of the liquid guiding column 2821. In another embodiment of this application, the diameter of the liquid guiding hole 2822 is smaller than the inner diameter of the hollow portion of the liquid guiding column 2821. Because the diameter of the liquid guiding hole 2822 is smaller than the inner diameter of the hollow portion of the liquid guiding column 2821, the liquid matrix flows out of the hollow portion of the liquid guiding column 2821 at a slower rate, thereby preventing liquid matrix leakage.

[0117] In one embodiment of this application, the aperture or diameter of the liquid guiding hole 2822 is 0.5mm-1.5mm. In another embodiment, the liquid guiding hole 2822 is circular, elongated, or other shaped opening, with an aperture or diameter of 0.5mm-1.5mm. This allows the liquid guiding hole 2822 to have a capillary effect, allowing the liquid matrix in the upper liquid storage chamber 2811 to flow out when the liquid reservoir 2 is in operation. When the liquid reservoir 2 is not in operation, the liquid guiding hole 2822 has a certain capillary effect on the liquid matrix within it, keeping the liquid matrix within the liquid guiding hole 2822 and preventing continuous outflow of the liquid matrix when the liquid reservoir 2 is not in operation, thus avoiding leakage. In one embodiment of this application, the aperture or diameter of the liquid guiding hole 2822 can be 0.5mm, 0.8mm, 1.0mm, 1.2mm, or 15mm.

[0118] In one embodiment of this application, a liquid guiding hole 2822 is disposed on the side wall of the liquid guiding column 2821.

[0119] In one embodiment of this application, after the liquid reservoir 2 is installed on the atomizer 1, the liquid guide column 2821 is inserted into the lower liquid reservoir 2911, and the liquid reservoir 2 can provide liquid matrix to the atomizing device 29.

[0120] In one embodiment of this application, the fluid replenisher 28 further includes a liquid output component 283, which is rotatable relative to the fourth housing 281 to open or close the liquid guide hole 2822. In one embodiment of this application, the liquid output component 283 has a first position and a second position relative to the fourth housing 281. When the liquid output component 283 is in the first position relative to the fourth housing 281, the liquid guide hole 2822 is open; when the liquid output component 283 is in the second position relative to the fourth housing 281, the liquid guide hole 2822 is closed.

[0121] In one embodiment of this application, when the atomizer 2 has multiple liquid storage chambers, the first liquid storage chamber 253 may include a first upper liquid storage chamber and a first lower liquid storage chamber, and the first upper liquid storage chamber can replenish the liquid matrix to the first lower liquid storage chamber; the second liquid storage chamber 254 may include a second upper liquid storage chamber and a second lower liquid storage chamber, and the second upper liquid storage chamber replenishes the liquid matrix to the second lower liquid storage chamber. In one embodiment of this application, the first upper liquid storage chamber may also provide the liquid matrix to the first lower liquid storage chamber by providing a liquid guiding hole on a liquid guiding column. In one embodiment of this application, the second upper liquid storage chamber may also provide the liquid matrix to the second lower liquid storage chamber by providing a liquid guiding hole on a liquid guiding column.

[0122] It should be noted that the preferred embodiments of this application are given in the specification and accompanying drawings, but are not limited to the embodiments described in this specification. Furthermore, those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
