The first heating member 110 is provided in the first liquid guide member 112 and is used to heat and atomize the atomized liquid infiltrated in the first liquid guide member 112. In some embodiments, the first fixing member 111 and the first liquid guide member 112 are cylindrical hollow structures. The first fixing member 111 can be but not limited to a steel pipe, and the first liquid guide member 112 can be but not limited to plant fiber cotton, etc. The second heating unit 12 includes a second heating element 120, a second fixing element 121, and a second liquid guiding element 122. The second liquid guiding element 122 is at least partially wrapped and fixed by the second fixing element 121.

[0039] like Figure 2 and Figure 3 As shown, Figure 3 yes Figure 1 Schematic diagram of another perspective of the explosion structure of the heating component of the embodiment, the connecting member 13 is connected between the first fixing member 111 and the second fixing member 121, and a connecting channel 130 is provided in the middle of the connecting member 13, and the connecting channel 130 is used to connect the first atomizing channel 1120 and the second atomizing channel 1220. The heating component 10 is composed of the connecting channel 130, the first atomizing channel 1120 and the second atomizing channel 1220 to form an atomizing gas rising channel. Optionally, the first atomizing channel 1120, the second atomizing channel 1220 and the connecting channel 130 are coaxially arranged, and the atomizing channel formed by the three can be, but is not limited to, extending vertically in the direction of atomizing gas transport ( Figure 3 In the X direction), the atomized gas in the first heating unit 11 passes through the first atomizing channel 1120 through the connecting channel 130 to reach the second atomizing channel 1220, and is then transported from the second atomizing channel 1220.

[0040] The first heating unit 11 and the second heating unit 12 are separated by the connecting piece 13, which not only solves the problem that the existing heating components can only adapt to a single flavor, but also the two heating components can output power independently and can be freely matched and switched, making the matching more flexible.

[0041] Please refer to Figure 1 and Figure 3 The first liquid guiding member 112 is located on the inner side of the first fixing member 111, and the first liquid guiding member 112 is in contact with the inner wall of the first fixing member 111. The first heating member 110 is located in the first liquid guiding member 112; the second liquid guiding member 122 is located on the inner side of the second fixing member 121, and the second liquid guiding member 122 is in contact with the inner wall of the second fixing member 121. The second heating member 120 is located in the second liquid guiding member 122; the first liquid guiding member 112 and the second liquid guiding member 122 are used to guide the atomized liquid into the first heating member 110 and the second heating member 120, respectively. Optionally, the first heating member 110 and the second heating member 120 are made of a resistance alloy material, and the first heating member body 1101 and the second heating member body 1200 are hollow cylindrical alloys with a honeycomb mesh shape. Conductive wires extend outward from the main body of the first heating member 110 and the second heating member 120, and the conductive wires extend to the power supply device, which can be but is not limited to a battery assembly.

[0042] Please refer to Figure 2 and Figure 3 In some embodiments, a first liquid guide groove 1110 is provided on the first fixing member 111, and the first liquid guide groove 1110 opens toward the first liquid guide member 112; a second liquid guide groove 1211 is provided on the second fixing member 121, and the second liquid guide groove 1211 opens toward the second liquid guide member 122. The first liquid guide groove 1110 and the second liquid guide groove 1211 are used to communicate with the liquid storage cotton 200, and the liquid storage cotton 200 conducts the atomized liquid to the first liquid guide member 112 and the second liquid guide member 122 through the first liquid guide groove 1110 and the second liquid guide groove 1211. 211 is arranged to match the shape of the first fixing member 111 and the second fixing member 121. The first liquid guide groove 1110 and the second liquid guide groove 1211 can be but not limited to square through grooves, and the number of the first liquid guide groove 1110 and the second liquid guide groove 1211 can be one or more. Because the first liquid guide groove 1110 and the second liquid guide groove 1211 need to conduct the atomized liquid in the liquid storage cotton 200 to the first liquid guide member 112 and the second liquid guide member 122, the opening of the first liquid guide groove 1110 and the opening of the second liquid guide groove 1211 are covered by the first liquid guide member 112 and the second liquid guide member 122.

[0043] like Figure 4 and Figure 5 As shown, Figure 4 yes Figure 1 Schematic diagram of the connector structure of the heating assembly in the embodiment, Figure 5 yes Figure 1Another perspective structural diagram of the heating assembly of an embodiment shows that the connector 13 is provided with a first connector 1300, a second connector 1301, and a separator 1302. The first connector 1300 is snap-fitted to the first fixing member 111, the second connector 1301 is snap-fitted to the second fixing member 121, and the separator 1302 is used to separate the first heating unit 11 and the second heating unit 12. In some embodiments, the connector 13 is snap-fitted to the first fixing member 111 and the second fixing member 121. The connector 13 has a cylindrical hollow structure. The separator 1302 is a separating protrusion on the connector 13 that is adapted to the snap-fitting requirement of the first fixing member 111 and the second fixing member 121. The shapes of the first connector 1300 and the second connector 1301 match the first fixing member 111 and the second fixing member 121.

[0044] Please refer to Figure 4 and Figure 5 In some embodiments, the outer annular surface of the connecting member 13 is provided with a groove 131, and the extending direction of the groove 131 is parallel to the extending direction of the connecting channel 130 of the connecting member 13 ( Figure 6 The groove 131 includes a wiring groove 1310 and a ventilation groove 1311. The wiring groove 1310 is used to accommodate the pins 1100 of the first heating element 110, and the ventilation groove 1311 ensures that the gas in the first heating unit 11 and the second heating unit 12 can pass through the connecting member 13. The groove 131 passes through the first connecting portion 1300, the second connecting portion 1301, and the partition 1302. The first heating element 110 extends from the inside of the first fixing member 111 through the wiring groove 1310 and along the extension direction of the second heating element 120.

[0045] Please refer to Figure 4 In some embodiments, the second fixing member 121 is provided with an avoidance groove 1210, the avoidance groove 1210 opens toward the wiring groove 1310, and the avoidance groove 1210 extends at least to the second liquid guiding member 122. The avoidance groove 1210 is used to avoid the extension of the first heating member 110, so that the first heating member 110 can extend from the first fixing member 111 to the outside of the second fixing member 121. At the same time, the avoidance groove 1210 also facilitates the installation of the first liquid guiding member 112 and the second liquid guiding member 122.

[0046] like Figure 6 As shown, Figure 6 yes Figure 5Schematic diagram of the AA cross-sectional structure of the heating component of the embodiment, the first heating element 110 includes a pin 1100 and a first heating element body 1101. The first heating element body 1101 is at least partially located in the first liquid-guiding member. The first heating element body 1101 is used to generate heat to atomize the liquid in the first liquid-guiding member 112; one end of the pin 1100 is connected to the first heating element body 1101, and the other end is wired to the power supply component. The pin 110 is used to introduce electrical energy into the first heating element 1101 body, so that the first heating element body 1101 converts the electrical energy into thermal energy. In some embodiments, the outside of the pin 1100 is wrapped with an insulating material, which can be but is not limited to rubber, polyethylene, etc. The insulating material is used to isolate the current in the pins 1100 with different potentials when different pins 1100 are in contact, ensuring that the current flows in the direction of the pin 1100.

[0047] like Figure 6 and Figure 7 As shown, Figure 7 yes Figure 6 Schematic diagram of the structure of the first heating element of the embodiment. In some embodiments, the first heating element 110 includes a first pin segment 1100a, a second pin segment 1100b, and a third pin segment 1100c. The first pin segment 1100a, the second pin segment 1100b, and the third pin segment 1100c are continuous conductive wires. The first pin segment 1100a is routed from the first heating element body 1101. The first pin segment 1100a is routed to the routing groove 1310 to the connection with the second pin segment 1100b, including at least one section parallel to the extension direction of the groove 131. In some embodiments, the first pin segment 1100a is routed from the first heating element body 1101 and is arranged along the extension direction of the groove 131 ( Figure 6 The first pin segment 1100a is bent and begins to extend perpendicularly to the extending direction of the groove 131 until it is flush with the height of the wiring groove 1310, and then bends and continues to extend along the extending direction of the groove 131 ( Figure 6 The second pin segment 1100b is connected to the first pin segment 1100a and the third pin segment 1100c. The second pin segment 1100b is an oblique conductive wire with one end forming a certain angle with the extension direction of the groove 131. The second pin segment 1100b extends from the inside of the second fixing member 121 to the outside of the second fixing member 121 through the wiring groove 1310. The third pin segment 1100c extends along the extension direction of the groove 131 ( Figure 6Optionally, when the second heating element 120 extends toward the power supply assembly, a certain distance is left between the second heating elements 120, allowing the first heating element 110 to pass through the middle of the second heating elements 120, thereby extending the first heating element 110 and the second heating element 120 together to the power supply assembly.

[0048] In some embodiments, the second heating unit 12 is provided with a ventilation groove 1212, such as Figure 1 and Figure 9 As shown, Figure 9 yes Figure 8 Schematic diagram of the cross-sectional structure of the atomizing device of the embodiment, BB, shows a ventilation groove 1212 disposed on the second fixing member 121. There may be one or more ventilation grooves 1212, which are in airflow communication with the second atomizing channel 1220. The ventilation grooves 1212 are used to balance the air pressure within the liquid storage tank body 20, the second liquid storage cotton 2001, and the second atomizing channel 1220. When the second heating unit 12 is heating, the air within the liquid storage tank body 20 and the second liquid storage cotton 2001 expands due to thermal expansion and contraction. The expanded air squeezes the second liquid storage cotton 2001, causing the atomized liquid in the second liquid storage cotton 2001 to leak. The provision of the ventilation grooves 1212 allows the liquid storage tank body 20 and the second liquid storage cotton 2001 to exchange air with the second atomizing channel 1220, thereby reducing the risk of leakage in high and low temperature environments.

[0049] The present application also provides an atomizing device, such as Figure 8 and Figure 9 As shown, Figure 8 This is a schematic diagram of the structure of an embodiment of the atomizing device of the present application, comprising a liquid storage tank 20 and the aforementioned heating assembly 10. Optionally, a protective shell may be provided outside the liquid storage tank 20 of the atomizing device 1 to further protect the liquid storage tank 20 and the heating assembly 10. A sealed liquid storage space is formed within the liquid storage tank 20, which is used to store atomized liquid; the aforementioned heating assembly 10 is disposed within the liquid storage tank 20 and atomizes the atomized liquid within the liquid storage tank 20.

[0050] like Figure 9 and Figure 10 As shown, Figure 10 yes Figure 8A schematic diagram of the exploded structure of an atomizer device in an embodiment shows a liquid storage chamber 20 comprising a partition 220, liquid storage cotton 200, and a sealing member 230. The liquid storage cotton 200 comprises a first liquid storage cotton 2000 and a second liquid storage cotton 2001. The partition 220 is located within the liquid storage chamber 20 and serves to separate the first liquid storage cotton 2000 from the second liquid storage cotton 2001. The first liquid storage cotton 2000 corresponds to the first liquid guide member 112 via a first liquid guide groove 1110, while the second liquid storage cotton 2001 corresponds to the second liquid guide member 122 via a second liquid guide groove 1211. The liquid storage cotton 200 is used to store atomized liquid. Using the partition 220 to separate the first and second liquid storage cottons 2000, 2001 allows for relative independence, enabling the conversion of different flavors by cooperating with the relatively independent first and second heating units 11, 12 of the heating assembly 10. The partition 220 is provided with a snap-in hole for fixing the heating component 10 . The sealing component 230 is located at the bottom of the liquid storage tank body 20 for supporting the heating component 10 and sealing the heating component 10 to prevent the atomized liquid from dripping.
