Those skilled in the art will explicitly and implicitly understand that the embodiments described herein may be combined with other embodiments.

[0036] Please refer to Figure 1 , Figure 1It is a schematic internal structure diagram of an embodiment of the atomizing device of the present application. This embodiment provides an atomizing device, including a housing 10, a bracket 20, and an air inlet pipe 40 communicating with the atmosphere. A mouthpiece 13 is provided on the housing 10, and an atomizing chamber 11 is provided inside the housing 10. Two liquid storage chambers 12 are separated by a partition in the atomizing chamber 11. In one embodiment, the liquid storage chamber 12 can accommodate a liquid storage medium, such as cotton and other liquid storage media, and the liquid storage medium stores an atomizing matrix. A first atomizing channel 14 and a second atomizing channel 15 are provided in the atomizing chamber 11. The first atomizing channel 14 and the second atomizing channel 15 are respectively provided in one of the liquid storage chambers 12, and the first atomizing channel 14 is connected with a first atomizing core 16 for heating the atomizing matrix, and the second atomizing channel 15 is connected with a second atomizing core 17 for heating the atomizing matrix. The first atomizing channel 14 and the second atomizing channel 15 penetrate through the atomizing chamber 11 and communicate with the mouthpiece 13, so that the atomizing matrix can be heated and atomized under the action of the first atomizing core 16 and the second atomizing core 17 and reach the mouthpiece 13 through the first atomizing channel 14 and the second atomizing channel 15 to be inhaled by the user. It can be understood that the two liquid storage chambers 12 are independent of each other, can store atomizing matrices of different flavors, and can also change the atomized proportion of atomizing matrices of different flavors by controlling the power of the first atomizing core 16 and the second atomizing core 17, so as to form various mixed flavors with different proportions.

[0037] Please refer to Figure 2 、 Figure 3 and Figure 4 , Figure 2 is Figure 1 a schematic structural diagram when the atomizing chamber and the bracket are disassembled in the embodiment, Figure 3 is Figure 2 a sectional view when the atomizing chamber and the bracket are assembled in the embodiment, Figure 4 is Figure 2 a sectional view of the atomizing chamber and the bracket assembled in another perspective in the embodiment.

[0038] The air inlet pipe 40 is fixedly connected to the bracket 20. The bracket 20 and the air inlet pipe 40 can be integrally formed. The air inlet pipe 40 communicates with the atmosphere and is used to balance the air pressure in the first atomizing channel 14 and the second atomizing channel 15. A flow guiding structure 30 is provided on the bracket 20 for guiding the air flow in the air inlet pipe 40 into the first atomizing channel 14 and the second atomizing channel 15.

[0039] Please refer to Figure 1 and Figure 5 , Figure 5FIG. 0 is a schematic structural view of a bracket in an embodiment of the atomizing device of the present application. Exemplarily, the bracket 20 includes a bottom plate 21 and a side plate 22. The bottom plate 21 is disposed on a side of the atomizing chamber 11 away from the mouthpiece 13. The side plate 22 is disposed around the periphery of the bottom plate 21 and extends in the direction of the atomizing chamber 11. The intake pipe 40 is disposed on a side of the bottom plate 21 away from the atomizing chamber 11. It can be understood that the intake pipe 40 and the bracket 20 can be an integral structure or a split structure. An air outlet is provided at the connection position between the bottom plate 21 and the intake pipe 40. An air inlet is provided at the bottom of the housing 10. The intake pipe 40 is docked with the air inlet and communicates with the atmosphere. The first atomizing channel 14 and the second atomizing channel 15 are respectively located on both sides of the intake pipe 40, and the distances from the first atomizing channel 14 and the second atomizing channel 15 to the intake pipe 40 are the same, ensuring that the distances for the intake pipe 40 to deliver air to the first atomizing channel 14 and the second atomizing channel 15 are the same. The guiding structure 30 is disposed between the bottom plate 21 and the atomizing chamber 11, and the guiding structure 30 is fixedly connected to the bottom plate 21, so that the air outlet end of the intake pipe 40 is spaced apart from the bottom of the atomizing chamber 11 via the guiding structure 30 to form a gap therebetween for the air to flow through. The guiding structure 30 includes a first guiding plate 31 and a second guiding plate 32. The first guiding plate 31 extends from the intake pipe 40 to the first atomizing channel 14, and the second guiding plate 32 extends from the intake pipe 40 to the second atomizing channel 15. The first guiding plate 31 and the second guiding plate 32 are respectively disposed on both sides of the intake pipe 40. The first guiding plate 31 and the second guiding plate 32 can be symmetrically disposed, and the first guiding plate 31 and the second guiding plate 32 are in an arc structure, which can reduce the air resistance and accelerate the airflow into the first atomizing channel 14 and the second atomizing channel 15.

[0040] The first atomizing core 16 communicates with one of the liquid storage chambers 12, and the second atomizing core 17 communicates with the other liquid storage chamber 12, so that the atomizing matrices in different liquid storage chambers 12 can respectively flow to the first atomizing core 16 and the second atomizing core 17. In some special cases, such as a low-pressure environment, being impacted, or long-term storage, the atomizing matrix may leak from the first atomizing core 16 and the second atomizing core 17; or, when the device is in a working state, after the first atomizing core 16 and the second atomizing core 17 heat and atomize the atomizing matrix, the smoke forms condensate after leaving the first atomizing core 16 and the second atomizing core 17 due to the temperature drop. The leaked or condensed atomizing matrix will flow down along the first atomizing channel 14 and the second atomizing channel 15. In the present application, since the intake pipe 40 communicates with the first atomizing channel 14 and the second atomizing channel 15, and the intake pipe 40 is a separate air passage, the leaked or condensed atomizing matrix can flow out of the housing 10 through the intake pipe 40, avoiding contamination of internal components.

[0041] Please refer to Figure 3 and Figure 5, in some embodiments, a first assembly hole 25 and a second assembly hole 26 are formed in the bottom plate 21 of the bracket 20. A first fitting portion 111 and a second fitting portion 112 are provided at the bottom of the atomization chamber 11. The first fitting portion 111 can pass through the first assembly hole 25 to be inserted into the bracket 20, and the second fitting portion 112 can pass through the second assembly hole 26 to be inserted into the bracket 20. The first assembly hole 25 and the second assembly hole 26 can be circular, oval, polygonal, etc., and no specific limitation is made here. As long as the first fitting portion 111 has a clearance fit with the first assembly hole 25 and the second fitting portion 112 has a clearance fit with the second assembly hole 26.

[0042] The atomization device further includes a control unit, and the control unit includes a circuit board 18. The circuit board 18 can be disposed at the lower part of the bracket 20. For example, the circuit board 18 can be abutted against the lower surface of the bottom plate 21 of the bracket 20, or can be disposed at other positions within the housing 10, and no specific limitation is made here. A first pin hole 1111 is formed in the first fitting portion 111 to facilitate the wire of the first atomization core 16 to pass through the first pin hole 1111 and be connected to the circuit board 18; similarly, a second pin hole 1121 is formed in the second fitting portion 112 to facilitate the wire of the second atomization core 17 to pass through the second pin hole 1121 and be connected to the circuit board 18. The first pin hole 1111 and the second pin hole 1121 are sealed by dispensing to prevent the atomization matrix in the liquid storage cavity 12 from leaking to the outside of the liquid storage cavity 12 of the housing through the first pin hole 1111 and the second pin hole 1121. Of course, in combination with the implementation mode in which the circuit board 18 can be abutted against the lower surface of the bottom plate 21 of the bracket 20, the wire of the first atomization core 16 passes through the first pin hole 1111 formed in the first fitting portion 111, and then passes through the first assembly hole 25 inserted with the first fitting portion 111, that is, passes through the bracket 20 and is connected to the circuit board 18 located below the bottom plate 21 of the bracket 20. After the wire passes through, the first pin hole 1111 is sealed by a dispensing process, so that the part of the wire located within the first pin hole 1111 can be surrounded by the first fitting portion 111, and the part connected to the circuit board 18 outside the first pin hole 1111 can be isolated from the first atomization channel 14 to avoid being affected by the first atomization channel 14.

[0043] It should be noted that the first flow guiding plate 31 isolates the first assembly hole 25 from the first atomization channel 14, the second flow guiding plate 32 isolates the second assembly hole 26 from the second atomization channel 15, and the first flow guiding plate 31, the second flow guiding plate 32, the bottom plate 21 and the side plate 22 enclose a collection cavity 27. The air inlet ends of the first atomization channel 14 and the second atomization channel 15 are isolated within the collection cavity 27, and the air outlet end of the air inlet pipe 40 is isolated within the collection cavity 27. In this way, it is possible to prevent the leaked or condensed atomization matrix from leaking into other cavities of the housing 10 through the first assembly hole 25 and the second assembly hole 26, and avoid affecting the working performance of other components such as the battery and the circuit board 18 within the housing 10.

[0044] Further, a first notch 311 is provided on one side of the first deflector 31 close to the first atomization channel 14, and a second notch 321 is provided on one side of the second deflector 32 close to the second atomization channel 15. By providing the first notch 311 and the second notch 321, the gaps between the first atomization channel 14 and the second atomization channel 15 and the bracket 20 can be increased. When the external air enters the first atomization channel 14 and the second atomization channel 15 via the air inlet pipe 40 and the deflector structure 30, the air resistance can be reduced, making the air flow smoother. In addition, the first notch 311 can communicate with the first atomization channel 14 and the first assembly hole 25, so that the external air can enter the first atomization channel 14 from the first notch 311 through the gap between the first assembly hole 25 and the first engaging portion 111; the second notch 321 can communicate with the second atomization channel 15 and the second assembly hole 26, so that the external air can enter the second atomization channel 15 from the second notch 321 through the gap between the second assembly hole 26 and the second engaging portion 112. In this way, the supply efficiency of the air during the suction process can be improved.

[0045] It should be noted that the first notch 311 does not penetrate through the first deflector 31, and similarly, the second notch 321 does not penetrate through the second deflector 32. That is to say, the first notch 311 is provided on one side of the first deflector 31 close to the atomization chamber 11 in the width direction of the first deflector 31, and the second notch 321 is provided on one side of the second deflector 32 close to the atomization chamber 11 in the width direction of the second deflector 32. The first deflector 31 and the second deflector 32 are continuous and unbroken, and the first deflector 31, the second deflector 32, and the side plate 22 can prevent the condensed atomization matrix from flowing out of the collection chamber 27 from the first notch 311 or the second notch 321 and leaking into other cavities of the housing 10 via the first assembly hole 25 and the second assembly hole 26.

[0046] Please refer to Figure 6 、 Figure 8 and Figure 9 , Figure 6 which is a schematic structural view of the bracket in another embodiment, Figure 8 is Figure 6 a top view of the bracket in the embodiment, Figure 9 is Figure 8 a cross-sectional view of the bracket at A-A in the embodiment.

[0047] In some embodiments, a negative pressure channel 23 is provided on the bracket 20. An air-operated switch 24 for controlling the start and stop of the atomization device is arranged in the negative pressure channel 23. The air-operated switch 24 is electrically connected to the circuit board 18. The negative pressure channel 23 communicates with the first atomization channel 14 and the second atomization channel 15. The first atomization channel 14 and the second atomization channel 15 are respectively located on both sides of the negative pressure channel 23, and the distance from the first atomization channel 14 to the negative pressure channel 23 is equal to the distance from the second atomization channel 15 to the negative pressure channel 23. The negative pressure channel 23 communicates with the first atomization channel 14 and the second atomization channel 15. Only the upper part of the air-operated switch 24 located in the negative pressure channel 23 communicates with the negative pressure channel 23, and the peripheral side of the lower part of the air-operated switch 24 is sealed. Combining with the embodiment where the circuit board 18 can be abutted against the lower surface of the bottom plate 21 of the bracket 20, the circuit board 18 and the bottom plate 21 of the bracket 20 enclose a sealed installation cavity, and the air-operated switch 24 is connected to the circuit board 18 and is located in the installation cavity. When the user inhales at the suction nozzle 13, external air enters the first atomization channel 14 and the second atomization channel 15 respectively through the air inlet pipe 40 and the diversion structure 30, so that a pressure difference will be formed on both sides of the air-operated switch 24, and then the air-operated switch 24 works to generate a first signal. After receiving the first signal, the control unit controls the first atomization core 16 and the second atomization core 17 to work to atomize the atomization matrix. The structure and working principle of controlling the first atomization core 16 and the second atomization core 17 to work through the air-operated switch 24 are well known to those skilled in the art and will not be described in detail here.

[0048] Further, the diversion structure 30 further includes a baffle 33. The air inlet pipe 40 and the negative pressure channel 23 are respectively arranged on both sides of the baffle 33. The baffle 33 separates the negative pressure channel 23 from the air inlet pipe 40, so that the negative pressure channel 23 forms a separate pneumatic starting channel. A notch 331 is provided on one side of the baffle 33 close to the atomization chamber 11. The negative pressure channel 23 communicates with the first atomization channel 14 and the second atomization channel 15 respectively through the notch 331.

[0049] Please refer to Figure 7 , Figure 7 is Figure 6Schematic structural diagram of the bracket in another perspective in the embodiment. It should be noted that the notch 331 extends from the side of the baffle 33 close to the atomization chamber 11 to the side away from the atomization chamber 11, and the notch 331 does not penetrate the baffle 33, that is, the notch 331 is arranged on the side of the baffle 33 close to the atomization chamber 11 along the width direction of the baffle 33. The baffle 33, the first deflector 31, the second deflector 32, the side plate 22 and the bottom plate 21 enclose to form a collection chamber 27, and the baffle 33 can prevent the leaked or condensed atomization matrix from flowing into the negative pressure channel 23 and affecting the pneumatic switch 24. By providing a negative pressure channel 23 independent of the air inlet pipe 40 for the pneumatic switch 24 on the bracket 20, the sensitivity of the pneumatic switch 24 during the use of the atomization device is ensured, so that the atomization device can quickly respond to the user's suction demand.

[0050] Please refer to Figure 10 , Figure 10 is a cross-sectional view of the bracket in another embodiment. In some embodiments, the air outlet end of the air inlet pipe 40 extends from the bottom plate 21 towards the atomization chamber 11, and there is a gap between the air inlet pipe 40 and the atomization chamber 11. That is to say, the air outlet end of the air inlet pipe 40 is higher than the top surface of the bottom plate 21, and the first deflector 31, the second deflector 32, the side plate 22 and the baffle 33 enclose to form a collection chamber 27, which can collect some leaked or condensed atomization matrix, and prevent the atomization matrix from directly leaking to the outside of the housing 10 through the air inlet pipe 40 and causing pollution to the outside of the housing 10, thereby reducing the user experience. In some scenarios, an uneven structure can also be provided on the bottom plate 21. For example, a number of grooves are opened on the bottom plate 21 to form a sump, which can store a certain amount of atomization matrix.

[0051] Furthermore, the air inlet pipe 40 is arranged close to the edge of the bottom plate 21, which is convenient for the installation of other components in the atomization device.

[0052] Furthermore, the diameter of the air inlet pipe 40 on the side away from the atomization chamber 11 is larger than the diameter of the air inlet pipe 40 on the side close to the bottom plate 21. The internal channel of the air inlet pipe 40 gradually converges in the direction close to the bracket 20, which can accelerate the air flow.

[0053] The above are only some embodiments of the present application, and thus do not limit the protection scope of the present application. Any equivalent device or equivalent process transformation made by using the content of the specification and drawings of the present application, or directly or indirectly applied to other related technical fields, shall be equally included in the patent protection scope of the present application.
