At the same time, the steps or actions in the method description can also be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a required sequence, unless otherwise specified that a certain sequence must be followed.

[0026] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0027] In existing atomizer products, in order to replenish the aerosol matrix in the liquid storage chamber, a liquid replenishing device is usually directly connected to the liquid storage chamber to add the aerosol matrix into the liquid storage chamber. In this way, the flow rate of the aerosol matrix is ​​large and difficult to control, which makes the aerosol matrix prone to leakage.

[0028] Please refer to Figures 1 to 6 An embodiment of the present application provides a flow guiding component 1 for guiding aerosol matrix in an atomizing device. The flow guiding component 1 includes a housing component 11 and a liquid guiding member 13 .

[0029] The housing assembly 11 is provided with a liquid storage chamber 111 and a liquid inlet 113. The liquid storage chamber 111 is used to store aerosol substrates. The liquid inlet 113 is connected to the liquid replenishing device 3. The aerosol substrates in the liquid replenishing device 3 are introduced into the liquid storage chamber 111 through the liquid inlet 113. The housing assembly 11 itself forms a receiving chamber for accommodating various components in the flow guiding assembly 1, including but not limited to the atomizer 12, the liquid guiding member 13, etc.; wherein, the function of the atomizer 12 is to heat the aerosol substrate to form an aerosol, and therefore the atomizer 12 is usually directly arranged in the liquid storage chamber 111 for storing the aerosol substrate, so that the atomizer 12 can directly heat the aerosol substrate in the liquid storage chamber 111 to generate an aerosol when it is working.

[0030] The atomizer 12 is composed of an atomizer core 121 and a liquid storage medium 122, wherein the liquid storage medium 122 is used to store the aerosol matrix, and the atomizer core 121 is used to heat the aerosol matrix in the liquid storage medium 122 to generate an aerosol, and finally discharge the aerosol outward through the air outlet 112 formed on the housing assembly. Exemplarily, the heating element in the atomizer core 121 can be a MESH grid heating element or a spiral heating wire, and the liquid storage medium 32 is a porous medium such as cotton, glass fiber, ceramic, etc.

[0031] The casing assembly 11 is provided with a liquid storage chamber 111, a liquid inlet 113, an air outlet 112 and other structures; in order to form these structures, the casing assembly 11 can be implemented by a one-layer or multi-layer structure, that is, the casing assembly 11 can be integrally formed by one component, or formed by a combination of multiple components, and each component can be made of the same or different materials, and can be directly or indirectly connected through connectors.

[0032] The liquid inlet 113 is connected to the liquid replenishing device 3; the liquid replenishing device 3 stores an aerosol matrix as a supplement to the aerosol matrix in the liquid storage chamber 111. The aerosol matrix in the liquid replenishing device 3 can flow into the liquid storage chamber 111.

[0033] The liquid inlet 113 may be connected to the liquid replenishing device 3 in a sealed manner, so that the aerosol matrix will not leak from the connection between the liquid inlet 113 and the liquid replenishing device 3. The sealed connection may be achieved by providing an elastic sealing member including a silicone ring at the liquid inlet 113.

[0034] The air outlet 112 is not only used to discharge the aerosol, but also used to communicate with the pneumatic switch through the pneumatic airway, so that the pneumatic switch can trigger the atomizer 12 to enter the working state by detecting the change in air pressure, and heat the aerosol matrix to generate the aerosol. The pneumatic airway and the main airway can be interconnected, and the pneumatic airway can be used as a branch of the main airway; or the pneumatic airway and the main airway can be isolated from each other, so that the two can avoid cross-flow.

[0035] Please refer to Figures 2 to 4 In order to reduce the flow rate of the aerosol matrix between the fluid replenishment device 3 and the liquid storage chamber 111, and to improve the stability of the fluid replenishment flow rate, the flow guide component 1 in the embodiment of the present application includes a fluid guide 13, and the fluid guide 13 includes a first end 131 and a second end 132 that are axially opposite to each other, the first end 131 is arranged on the liquid storage chamber 111 side, and the second end 132 is arranged on the liquid inlet 113 side, and the second end 132 can be inserted into the fluid replenishment device 3 through the liquid inlet 113; the fluid guide 13 is used to conduct the aerosol matrix in the fluid replenishment device 3 to the liquid storage chamber 111, and the atomizer 12 is used to heat the aerosol matrix in the liquid storage chamber 111 to generate an aerosol and discharge it from the air outlet 112. Among them, the first end 131 of the liquid guide member 13 refers to the liquid guide member 13 being detachably fixedly connected to other components in the flow guide assembly 1 through the first end 131 to prevent the liquid guide member 13 from being separated from the flow guide assembly 1; and the second end 132 refers to the end of the liquid guide member 13 that is not involved in the connection. The second end 132 has no other constraints except the body of the liquid guide member 13, so the second end 132 can be used as the starting point for the aerosol matrix to flow out of the liquid infusion device 3, and the aerosol matrix can enter the liquid storage chamber 111 from the liquid infusion device 3 through the second end 132 of the liquid guide member 13 along the liquid guide member 13 in sequence. Since the second end 132 of the liquid guide member 13 can be inserted into the liquid infusion device 3, the second end 132 reduces the opening area of ​​the liquid infusion device 3, thereby reducing the flow rate of the aerosol matrix; and the aerosol matrix in the liquid infusion device 3 will also flow with the liquid guide member 13, which improves the stability of the aerosol matrix in the process of being conducted to the liquid storage chamber 111, and greatly reduces the risk of leakage.

[0036] In one embodiment, the first end 131 is not connected to other components in the flow guiding assembly 1, but the flow guiding member 13 is kept at a preset position through the second end 132. Exemplarily, the second end 132 and the second free end 142 are fixedly connected.

[0037] The function of the liquid guide 13 is to guide the aerosol matrix so that the aerosol matrix can flow along the layout direction of the liquid guide 13; based on the different flow guiding principles of the liquid guide 13, it can include surface flow guiding or capillary flow guiding. Among them, surface flow guiding means that the aerosol matrix will flow along the outer surface of the liquid guide 13. At this time, the liquid guide 13 acts as a carrier for the flow of the aerosol matrix and provides a flow direction for the aerosol matrix, thereby avoiding the unstable flow rate caused by the non-directional flow of the aerosol matrix; and capillary flow guiding means that the liquid guide 13 uses the capillary phenomenon to absorb the aerosol matrix and allow the aerosol matrix to flow in the liquid guide 13. Specifically, the liquid guide 13 corresponding to the surface flow guiding can be any surface dense component, including but not limited to glass, silica gel and other surface dense materials; and the liquid guide 13 corresponding to the capillary flow guiding can be a porous material such as ceramics and liquid storage cotton. In some embodiments of the present application, the material of the liquid guide 13 is silica gel to achieve surface flow guiding.

[0038] The purpose of the liquid guiding member 13 is to drain the aerosol matrix and reduce the opening area of ​​the liquid replenishing device 3; wherein, in order to drain the aerosol matrix into the liquid storage chamber 111, the first end 131 of the liquid guiding member 13 is arranged close to the liquid storage chamber 111, and the liquid guiding member 13 is connected to the liquid storage chamber 111, so that the aerosol matrix on the liquid guiding member 13 can enter the liquid storage chamber 111 along the connection with the liquid storage chamber 111.

[0039] In some alternative embodiments, please refer to Figure 5 and Figure 6In order to facilitate the insertion of the liquid guide member 13 into the liquid infusion device 3, the liquid guide component 1 in the present application may also include a puncture tube 14, which is sleeved on the liquid guide member 13. The puncture tube 14 includes a second fixed end 141 and a second free end 142 that are arranged opposite to each other in the axial direction. The second fixed end 141 is arranged on the side of the liquid storage cavity 111, and the second free end 142 is arranged on the side of the liquid inlet 113; the second free end 142 is used to pass through the liquid inlet 113 and be inserted into the liquid infusion device 3, so that the second end 132 is inserted into the liquid infusion device 3 through the inner space of the tube wall of the puncture tube 14. Similar to the liquid guide member 13, the puncture tube 14 also includes a second fixed end 141 and a second free end 142 along the axial direction, wherein the second fixed end 141 is also used to be fixedly connected with other parts of the liquid guide member 1, and the second free end 142 can be inserted into the liquid infusion device 3. The liquid guiding member 13 itself can be inserted into the liquid infusion device 3 to achieve diversion, and the purpose of setting the puncture tube 14 is that the puncture tube 14 can be used to directly destroy the cover at the opening of the liquid infusion device 3 without specially removing the cover, and at the same time, it can be avoided that the cover is directly destroyed by the liquid guiding member 13, which will cause the liquid guiding member 13 to be in direct and close contact with the remaining cover; and the cover is destroyed by the puncture tube 14, as a result, the outer wall of the puncture tube 14 is in close contact with the cover, and the liquid guiding member 13 is inserted into the liquid infusion device 3 through the internal space of the tube wall of the puncture tube 14, that is, the function of the liquid guiding member 13 is not affected, the liquid guiding member 13 can divert normally, and because the puncture tube 14 has destroyed the cover, the liquid guiding member 13 can be more easily inserted into the liquid infusion device 3.

[0040] In some optional embodiments, in order to improve the diversion effect, a liquid storage gap 130 is formed between the puncture tube 14 and the liquid guiding member 13. The purpose of setting the liquid storage gap 130 is that when the liquid guiding member 13 guides the aerosol matrix in the fluid infusion device 3, the aerosol matrix flows along the setting direction of the liquid guiding member 13, and the liquid storage gap 130 can serve as the space required for the flow of the aerosol matrix.

[0041] In some optional embodiments, in order to improve the diversion effect, the second fixed end 141 of the puncture tube 14 can be directly fixedly arranged in the liquid storage cavity 111, and the tube wall of the puncture tube 14 located in the liquid storage cavity 111 is provided with at least one liquid guide hole 143, and the liquid guide hole 143 connects the liquid storage gap 130 and the liquid storage cavity 111. Since the liquid guide hole 143 connects the liquid storage gap 130 and the liquid storage cavity 111, when the aerosol matrix flows in the liquid storage gap 130, it can enter the liquid storage cavity 111 through the liquid guide hole 143. The liquid guide hole 143 can be arranged around the tube wall of the puncture tube 14 to avoid blockage of the aerosol matrix in the liquid storage cavity 111. Among them, the second fixed end 141 of the puncture tube 14 is fixedly arranged in the liquid storage cavity 111, and can be fixedly connected by a detachable connection structure, including but not limited to a snap connection, a threaded fastening connection, etc.

[0042] In some optional embodiments, in order to fix the puncture tube 14, the liquid guide member 13 may further include a mounting flange 133 arranged along the circumferential direction, and the liquid guide member 13 and the puncture tube 14 form an interference connection through the mounting flange 133. The mounting flange 133 can make the size of the liquid guide member 13 at the corresponding position larger, so that an interference fit can be formed with the inner wall of the puncture tube 14, so that the puncture tube 14 can be indirectly fixedly connected to the guide assembly 1 through the liquid guide member 13.

[0043] In some optional embodiments, in order to improve the guiding effect of the liquid guiding member 13, the length of the second end 132 inserted into the liquid infusion device 3 is greater than the length of the second free end 142 inserted into the liquid infusion device 3. This means that the liquid guiding member 13 is deeper into the liquid infusion device 3 than the puncture tube 14, so that the aerosol matrix in the liquid infusion device 3 will contact the liquid guiding member 13 earlier, so that the liquid guiding member 13 can better achieve the guiding effect.

[0044] In some optional embodiments, in order to fix the liquid guiding member 13 itself and improve the guiding effect of the liquid guiding member 13, the first end 131 of the liquid guiding member 13 can be directly fixed in the liquid storage chamber 111, and the first end 131 of the liquid guiding member 13 is fixedly connected to the inner wall of the liquid storage chamber 111 away from the liquid inlet 113. The end point of the liquid guiding member 13 for guiding the aerosol matrix is ​​in the liquid storage chamber 111, so the liquid guiding member 13 can be directly inserted into the liquid storage chamber 111, so that the aerosol matrix can directly flow into the liquid storage chamber 111 when flowing along the liquid guiding member 13; at the same time, the liquid guiding member 13 can be directly fixed by the inner wall of the liquid storage chamber 111, and the fixing method includes but is not limited to: the liquid guiding member 13 is directly integrally formed with the inner wall of the liquid storage chamber 111; the liquid guiding member 13 is fixedly connected to the inner wall of the liquid storage chamber 111 by threaded fastening; the liquid guiding member 13 is fixedly connected to the inner wall of the liquid storage chamber 111 by interference fit; and the liquid guiding member 13 can also be fixedly connected to the inner wall of the liquid storage chamber 111 by bonding.

[0045] In some optional embodiments, the cross-sectional area of ​​the liquid guide 13 gradually decreases from the first end 131 to the second end 132. The specific form of the liquid guide 13 can be a variable diameter cylinder, the outer diameter of which gradually decreases from the first end 131 to the second end 132 of the liquid guide 13, so that the second end 132 can be inserted into the liquid infusion device 3 and can be adapted to liquid infusion devices 3 with different opening sizes. In some embodiments, the liquid guide 13 can also be used to destroy the cover of the liquid infusion device 3, so the smaller the outer diameter of the second end 132 of the liquid guide 13, the better the destroying effect on the cover.

[0046] In some alternative embodiments, please refer to Figure 3 The gas outlet 112 and the atomizer 12 can be coaxially arranged along the first axis L1, and the liquid guide 13 and the liquid inlet 113 can also be coaxially arranged along the second axis L2, and the first axis L1 and the second axis L2 are mutually offset. The function of the atomizer 12 is to heat the aerosol matrix to generate aerosol, so the atomizer 12 is coaxially arranged with the gas outlet 112, so that the aerosol generated by the atomizer 12 can be discharged more directly from the gas outlet 112.

[0047] The liquid guiding member 13 and the liquid inlet 113 are also coaxially arranged, so the liquid guiding effect of the liquid guiding member 13 can be guaranteed, and the first axis L1 formed by the air outlet 112 and the atomizer 12 and the second axis L2 formed by the liquid guiding member 13 and the liquid inlet 113 are offset from each other, indicating that the first axis L1 and the second axis L2 are not on the same axis. In this way, the internal space of the guide component 1 can be optimized, including but not limited to facilitating the design of the air inlet channel at the bottom of the atomizer 12, and avoiding the phenomenon that the aerosol matrix is ​​too concentrated on the side of the atomizer 12 after the guide when the coaxial arrangement is used.

[0048] The flow guide component 1 provided in the embodiment of the present application is provided with a liquid guide member 13 between the liquid storage chamber 111 and the liquid inlet 113, and the liquid guide member 13 is used to guide the aerosol matrix, so that the aerosol matrix in the liquid replenishing device 3 enters the liquid storage chamber 111 along the liquid guide member 13, which can effectively improve the stability of the flow of the aerosol matrix; and the presence of the liquid guide member 13 reduces the opening area of ​​the liquid replenishing device 3, thereby effectively reducing the flow rate of the aerosol matrix, and further avoiding the leakage of the aerosol matrix.

[0049] The present application also provides an atomization device, please refer to Figure 7 , the atomizing device includes an atomizer 12, a power supply assembly 2, a liquid replenishing device 3 and a flow guide assembly 1 in the embodiment of the present application; the atomizer 12 is fixedly arranged in the liquid storage chamber 111, and the power supply assembly 2 is fixedly connected to the housing assembly 11, and is used to supply power to the atomizer 12; the liquid replenishing device 3 is connected to the liquid inlet 113, and the second end 132 of the liquid guide 13 can be inserted into the liquid replenishing device 3 through the liquid inlet 113. Among them, the power supply assembly 2 is used to provide electrical energy to the atomizer 12, and the atomizer 12 is used to heat the aerosol matrix into an aerosol. The atomizing device can be a disposable product or a cartridge-changing product. For a disposable atomizing device, the atomizer 12 and the power supply assembly 2 can be fixedly connected; for a cartridge-changing atomizing device, the atomizer 12 and the power supply assembly 2 can be detachably connected, and the atomizer 12 and the power supply assembly 2 can be replaced according to the usage.

[0050] An accommodating space is formed in the liquid replenishing device 3 for storing aerosol substrates. The liquid replenishing device 3 is connected to the liquid inlet 113, and the second end 132 of the liquid guide 13 can be inserted into the liquid replenishing device 3 through the location of the liquid inlet 113, so that the aerosol substrate in the liquid replenishing device 3 can flow out along the liquid guide 13 and be conducted by the liquid guide 13 to the liquid storage chamber 111.

[0051] The above-mentioned atomization device is only one embodiment of the present application. Other atomization devices having corresponding structures in the embodiments of the present application are also within the protection scope of the present application, and the specific internal structure of the atomization device will not be described in detail.

For those skilled in the art of the present invention, some simple deductions, deformations or substitutions can be made based on the idea of ​​the present invention.
