Description

Technical Field

[0001] This utility model relates to the field of atomization technology, and in particular to an atomizer and an electronic atomization device. Background Technology

[0002] An electronic atomizing device is a device used to generate aerosols. In related technologies, the atomizer of an electronic atomizing device includes a liquid storage chamber and an atomizing core disposed within the liquid storage chamber; the atomizing core is equipped with a conductive element and an atomizing assembly; the aerosol generating matrix in the liquid storage chamber can flow to the conductive element, which guides the aerosol generating matrix to the atomizing assembly, whereby the atomizing assembly heats and atomizes the aerosol generating matrix.

[0003] However, in traditional atomizers, the aerosol generation matrix in the reservoir is prone to leakage when the external temperature or air pressure changes.

[0004] The above information disclosed in the background art of this application is only for understanding the background of the concept of this application, and does not indicate or imply that it includes information of the prior art. Utility Model Content

[0005] Therefore, it is necessary to provide an atomizer and an electronic atomization device to address the above problems.

[0006] An atomizer comprising:

[0007] Atomizing component for atomizing an aerosol generation matrix to form an aerosol;

[0008] A storage bin is provided for loading the aerosol generating matrix. The storage bin is connected to the atomizing component via a feeding channel, which can deliver the aerosol generating matrix to the atomizing component.

[0009] An overflow channel, wherein the overflow channel is connected to the storage silo or the feeding channel; and

[0010] An overflow volume is provided in the space outside the storage bin, atomizing component and feeding channel and is connected to the overflow channel. The overflow volume is configured to contain at least a portion of the aerosol generating matrix flowing through the overflow channel when the air pressure in the storage bin is greater than the external air pressure, and / or return at least a portion of the aerosol generating matrix to the overflow channel when the air pressure in the storage bin is less than the external air pressure.

[0011] The aforementioned atomizer can achieve at least the following beneficial effects: When the air pressure inside the storage chamber is greater than the external air pressure, the overflow volume can contain the aerosol generation matrix flowing in from the overflow channel, preventing the aerosol generation matrix from leaking out of the atomizing component and avoiding leakage problems; when the air pressure inside the storage chamber is less than the external air pressure, the aerosol generation matrix in the overflow volume can automatically flow back to the storage chamber or the supply channel through the overflow channel, ensuring a continuous liquid supply to the atomizing component and avoiding dry burning problems caused by insufficient liquid supply. It is understandable that without an overflow volume, when the air pressure inside the storage chamber increases, the expanding gas will directly squeeze the aerosol generation matrix towards the atomizing component, causing liquid leakage. When the air pressure inside the storage chamber decreases, it may lead to insufficient subsequent liquid supply and the risk of dry burning. In other words, the overflow volume of the atomizer in this application has an automatic adjustment function. It can absorb excess aerosol generation matrix when the storage chamber is under positive pressure relative to the outside, and return the aerosol generation matrix when the storage chamber is under negative pressure relative to the outside, thus maintaining the system pressure balance. The overflow volume can buffer and temporarily store the aerosol generation matrix during transport. Without additional power or complex control mechanisms, it can effectively cope with the volume changes of the aerosol generation matrix in the storage chamber caused by temperature or air pressure fluctuations, ensuring the stable operation of the atomizer under different environmental conditions. It has a simple structure, low cost, and high reliability.

[0012] In some embodiments, the overflow volume includes a storage unit configured to receive at least a portion of the aerosol-generating matrix flowing through the overflow channel when the air pressure in the storage hopper is greater than the external air pressure, and / or to return at least a portion of the aerosol-generating matrix to the overflow channel when the air pressure in the storage hopper is less than the external air pressure.

[0013] In some embodiments, the atomizing component includes a heating element for heating the aerosol generating matrix to atomize and generate aerosol, and a suction element connected to the heating element. The suction element is connected to the feeding channel and is used to draw up the aerosol generating matrix. Both the storage element and the suction element are porous structures.

[0014] In some embodiments, the porosity of the storage component is greater than that of the suction component. This greater porosity allows the storage component to absorb or release the aerosol-generating matrix more quickly in response to pressure changes. When the volume of the aerosol-generating matrix in the storage silo increases and tends to overflow, the greater porosity of the storage component reduces the resistance to the aerosol-generating matrix moving towards it. This means the aerosol-generating matrix will preferentially flow towards the storage component during volume expansion, reducing the risk of leakage into the suction component and preventing liquid leakage.

[0015] In some embodiments, the overflow volume further includes a backflow channel communicating with the overflow channel. The backflow channel is configured to collect at least a portion of the aerosol-generating matrix flowing through the overflow channel when the pressure inside the storage silo is greater than the external pressure, and / or return at least a portion of the aerosol-generating matrix to the overflow channel when the pressure inside the storage silo is less than the external pressure. The backflow channel can absorb excess liquid when the storage silo is under positive pressure relative to the external environment, and can release stored liquid when the storage silo is under negative pressure relative to the external environment, maintaining system pressure balance.

[0016] In some embodiments, the backflow channel is an opening formed in the storage component. Directly opening an opening in the storage component to form the backflow channel reduces the number of independent parts, and the opening process of the backflow channel is completed simultaneously with the forming of the storage component, which helps to reduce manufacturing costs.

[0017] In some embodiments, the atomizer further includes an atomizing seat, the overflow volume is disposed within the atomizing seat, and the backflow channel is an opening formed on the atomizing seat. Directly opening an opening on the atomizing seat to form the backflow channel reduces the number of independent components, and the opening process of the backflow channel is completed simultaneously with the forming of the atomizing seat, which helps to reduce manufacturing costs.

[0018] In some embodiments, the overflow volume also includes a hollow internal suction pipe that encloses the suction channel forming the suction channel.

[0019] In some embodiments, the back suction pipe passes through the storage container.

[0020] In some embodiments, the suction pipe is clamped between the cavity wall of the receiving cavity and the outer peripheral surface of the storage component.

[0021] In some embodiments, the atomizer further includes an atomizing seat with a receiving cavity. The storage component is embedded in the receiving cavity, and a back-suction groove is formed on the cavity wall. The groove wall and the outer peripheral surface of the storage component enclose the back-suction channel. By directly machining the back-suction groove on the cavity wall and fitting it with the outer peripheral surface of the storage component to form the back-suction channel, the number of assembly parts is reduced, manufacturing costs are lowered, and the overall structure's compactness and reliability are improved.

[0022] In some embodiments, the atomizer further includes an atomizing seat with a receiving cavity. The storage component is disposed within the receiving cavity, and a back-suction groove is formed on the outer peripheral surface of the storage component. The wall of the back-suction groove and the cavity wall of the receiving cavity enclose the back-suction channel. By directly machining the back-suction groove on the outer peripheral surface of the storage component and fitting it with the cavity wall to form the back-suction channel, the number of assembly parts is reduced, manufacturing costs are lowered, and the overall structure's compactness and reliability are improved.

[0023] In some embodiments, the overflow volume includes a backflow channel communicating with the overflow channel. The backflow channel is configured to collect at least a portion of the aerosol-generating matrix flowing through the overflow channel when the pressure inside the storage silo is greater than the external pressure, and / or to return at least a portion of the aerosol-generating matrix to the overflow channel when the pressure inside the storage silo is less than the external pressure. The backflow channel absorbs excess liquid when the storage silo is under positive pressure and releases stored liquid when it is under negative pressure, maintaining system pressure balance.

[0024] In some embodiments, the overflow volume includes a hollow internal suction pipe that encloses the suction channel forming the suction channel.

[0025] In some embodiments, the atomizer further includes an atomizing seat, the overflow volume is disposed within the atomizing seat, and the backflow channel is an opening formed on the atomizing seat.

[0026] In some embodiments, the feeding channel includes a first feeding space connected to the storage bin and a second feeding space connected to the first feeding space. The second feeding space is connected to the atomizing component. The atomizer further includes a guide component disposed within the second feeding space. The guide component has a porous structure, and its porosity is greater than that of the suction component. Furthermore, the porosity of the storage bin is greater than that of the guide component. The greater porosity of the guide component allows for faster absorption of the aerosol generation matrix from the second feeding space, while its structure also slows down the flow of the aerosol generation matrix, preventing it from being absorbed too quickly by the suction component and reducing the risk of leakage from the suction component. During the process of heating the aerosol generating matrix by the heating element to form an aerosol, the aerosol generating matrix in the suction element may also undergo certain property changes due to the heat. The guide element can also reduce the backflow of the aerosol generating matrix in the suction element, thereby ensuring the cleanliness of the aerosol generating matrix in the feeding channel, storage bin, overflow channel and overflow volume.

[0027] In some embodiments, the atomizer further includes an air inlet, through which the overflow volume communicates with the outside atmosphere.

[0028] In some embodiments, the overflow channel is an opening formed in the storage bin or the feeding channel.

[0029] In some embodiments, the atomizer further includes a battery assembly electrically connected to the atomizing assembly and providing power to the atomizing assembly.

[0030] This application also provides an electronic atomizing device, which includes a power supply component and an atomizer as described in any of the above embodiments, wherein the power supply component is electrically connected to the atomizing component and provides energy to the atomizing component.

[0031] In some embodiments, the atomizer is detachably connected to the power supply component.

[0032] In some embodiments, the atomizer is fixedly connected to the power supply component.

[0033] Since the aforementioned electronic atomizing device includes the atomizer described in any of the above embodiments, it also provides at least the following beneficial effects: when the air pressure in the storage chamber is greater than the external air pressure, the overflow volume can accommodate the aerosol generating matrix flowing in from the overflow channel, preventing the aerosol generating matrix from leaking out of the atomizing component and avoiding leakage problems; when the air pressure in the storage chamber is less than the external air pressure, the aerosol generating matrix in the overflow volume can automatically flow back to the storage chamber or the feeding channel through the overflow channel, ensuring a continuous liquid supply to the atomizing component and avoiding dry burning problems caused by insufficient liquid supply. It is understandable that without an overflow volume, when the air pressure in the storage chamber increases, the expanding gas will directly squeeze the aerosol generating matrix towards the atomizing component, causing liquid leakage. When the air pressure in the storage chamber decreases, it may lead to insufficient subsequent liquid supply and the risk of dry burning. In other words, the overflow volume of the atomizer in this application has an automatic adjustment function. It can absorb excess aerosol generation matrix when the storage chamber is under positive pressure relative to the outside, and return the aerosol generation matrix when the storage chamber is under negative pressure relative to the outside, maintaining system pressure balance. The overflow volume can buffer and temporarily store the aerosol generation matrix during transport. Without additional power or complex control mechanisms, it relies solely on the pressure difference to drive the flow of the aerosol generation matrix, effectively addressing volume changes in the aerosol generation matrix in the storage chamber caused by temperature or pressure fluctuations. This ensures stable operation of the atomizer under different environmental conditions, resulting in a simple structure, low cost, and high reliability. The power supply component can provide energy to the atomization component of the atomizer, enabling the atomization component to atomize the aerosol generation matrix into an aerosol that can be inhaled by the user.

[0054] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0055] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 In some embodiments, this application provides an atomizer 11, which includes an atomizing base 100, an atomizing component 200, a storage bin 300, an overflow channel 400, and an overflow volume 500. Specifically, the atomizing base 100 is provided with a feeding channel 111; the atomizing component 200 is disposed within the atomizing base 100 and is used to atomize the aerosol generating matrix to form an aerosol; the storage bin 300 is used to load the aerosol generating matrix, and the storage bin 300 is connected to the atomizing component 200 through the feeding channel 111, which transports the aerosol generating matrix to the atomizing component 200. Figure 4 The dotted line with a single arrowhead can be considered as a schematic diagram of the conveying direction of the aerosol generating matrix from the storage bin 300 through the feeding channel 111 to the atomizing component 200. The overflow channel 400 is connected to the storage bin 300 or the feeding channel 111. The overflow volume 500 is located inside the atomizing seat 100 and is connected to the overflow channel 400. The atomizing seat 100 isolates the overflow volume 500 from the atomizing component 200, the feeding channel 111, and the storage bin 300.

[0056] In some embodiments, one end of the overflow channel 400 is connected to at least one of the storage silo 300 or the feeding channel 111, and the other end is connected to the overflow volume 500. See also Figure 4 In this specific embodiment, the overflow channel 400 is a through hole formed in the atomizing seat 100, with one side communicating with the feeding channel 111 and the other side communicating with the overflow volume 500. The overflow volume 500 is disposed within the atomizing seat 100, which may include the entire overflow volume 500 located within the atomizing seat 100, or a portion of the overflow volume 500 located within the atomizing seat 100, or at least a portion of the overflow volume 500 formed by the atomizing seat 100, such as by a groove on the atomizing seat 100 (which may be the receiving cavity 123 mentioned below).

[0057] Figure 4The dotted lines with double arrows can be considered as a schematic representation of the transport direction of the aerosol generating matrix at the locations of the overflow channel 400 and overflow volume 500. That is, the flow direction of the aerosol generating matrix within the overflow channel 400 may vary under different conditions. The overflow volume 500 is configured to receive at least a portion of the aerosol generating matrix flowing through the overflow channel 400 when the air pressure within the storage silo 300 is greater than the external air pressure, and / or to return at least a portion of the aerosol generating matrix to the overflow channel 400 when the air pressure within the storage silo 300 is less than the external air pressure. The aerosol generating matrix can refer to a material that can be atomized under certain conditions to provide aerosol components, and may include, but is not limited to, liquid atomizing matrices.

[0058] The atomizer 11 described above can achieve at least the following beneficial effects: When the air pressure inside the storage chamber 300 is greater than the external air pressure, the overflow volume 500 can contain the aerosol generating matrix flowing in from the overflow channel 400, preventing the aerosol generating matrix from leaking out of the atomizing component 200 and avoiding leakage problems; when the air pressure inside the storage chamber 300 is less than the external air pressure, the aerosol generating matrix in the overflow volume 500 can automatically flow back to the storage chamber 300 or the supply channel 111 through the overflow channel 400, ensuring a continuous liquid supply to the atomizing component 200 and avoiding dry burning problems caused by insufficient liquid supply. It is understandable that if the overflow volume 500 is not provided, when the air pressure inside the storage chamber 300 increases, the expanding gas will directly squeeze the aerosol generating matrix towards the atomizing component 200, causing liquid leakage. When the air pressure inside the storage chamber 300 decreases, it may lead to insufficient subsequent liquid supply and the risk of dry burning. In other words, the overflow volume 500 of the atomizer 11 of this application has an automatic adjustment function. It can absorb excess aerosol generation matrix when the storage chamber 300 is under positive pressure relative to the outside, and return the aerosol generation matrix when the storage chamber 300 is under negative pressure relative to the outside, thus maintaining the system pressure balance. The overflow volume 500 can buffer and temporarily store the aerosol generation matrix. Without additional power or complex control mechanisms, it can effectively cope with the volume change of the aerosol generation matrix in the storage chamber 300 caused by temperature or air pressure fluctuations, and ensure the stable operation of the atomizer 11 under different environmental conditions. It has a simple structure, low cost and high reliability.

[0059] Please see Figure 4In some embodiments, the atomizing seat 100 has a feed inlet 112 at its top, and the feeding channel 111 communicates with the storage bin 300 through the feed inlet 112. The atomizing seat 100 also has an air inlet 131 at its bottom, and the overflow volume 500 communicates with the external atmosphere through the air inlet 131. The feed inlet 112 at the top of the atomizing seat 100 allows for gravity-assisted feeding, ensuring smooth flow of liquid from the storage bin 300 into the feeding channel 111, reducing the risk of feed interruption or bubble blockage, and improving atomization continuity. The air inlet 131 at the bottom of the atomizing seat 100, which communicates with the overflow volume 500, maintains internal and external pressure balance and accelerates liquid reflux during the backflow phase, reducing the residue of the aerosol generation matrix in the overflow volume 500 and improving the utilization rate of the aerosol generation matrix.

[0060] like Figure 4 and Figure 9 As shown, in some embodiments, the atomizing base 100 has a partition 122, the overflow channel 400 includes an opening formed in the partition 122, the storage bin 300, the feeding channel 111 and the atomizing assembly 200 are located on one side of the partition 122, the overflow volume 500 is located on the other side of the partition 122, and the partition 122 isolates the overflow volume 500 from the atomizing assembly 200, the feeding channel 111 and the storage bin 300.

[0061] Please see Figure 1 , Figure 4 and Figure 17 In some embodiments, when the atomizer 11 is connected to the power supply assembly 12 mentioned below, the power supply assembly 12 has a mounting cavity 13 for inserting the atomizer 11, the atomizing base 100 has an atomizing cavity 114, and the atomizing assembly 200 is disposed within the atomizing cavity 114. In a specific embodiment disclosed, the storage bin 300, the feeding channel 111, the atomizing assembly 200, and the atomizing cavity 114 are all located above the partition 122, and the partition 122 forms the lowest point of the storage bin 300, the feeding channel 111, the atomizing assembly 200, and the atomizing cavity 114. When the atomizer 11 is inserted into the power supply assembly 12, the storage bin 300, the feeding channel 111, the atomizing assembly 200, and the atomizing cavity 114 are not located within the mounting cavity 13 of the power supply assembly 12.

[0062] The end face forming the opening of the mounting cavity 13 of the power supply component 12 is defined as the first end face A. In some embodiments, the power supply component 12 is placed on a bearing surface B, which can be a horizontal plane, an inclined plane, a vertical plane, etc. For example, the bearing surface B is a horizontal plane, and when the atomizer 11 is connected to the power supply component 12, the atomizer 11 is located above the power supply component 12, and the highest point of the first end face A is not higher than the lowest point of the storage bin 300, the feeding channel 111, the atomizing component 200, and the atomizing chamber 114.

[0063] In the public examples, please refer to Figure 4 If the lowest point of the feeding channel 111 is not higher than the lowest point of the atomizing chamber 114 and the atomizing component 200, and the partition 122 forms the bottom surface of the feeding channel 111, then the highest point of the first end face A is not higher than the lowest point of the feeding channel 111, and the highest point of the first end face A is not higher than the partition 122.

[0064] In other examples, the lowest point of the atomizing chamber 114 is not higher than the lowest point of the storage bin 300, the feeding channel 111, and the atomizing component 200; therefore, the highest point of the first end face A is not higher than the lowest point of the storage bin and the atomizing chamber 410. If the partition 122 can form the bottom of the atomizing chamber 114, then the highest point of the first end face A is not higher than the partition 122. In still other examples, the lowest point of the atomizing component 200 is not higher than the lowest point of the storage bin 300, the feeding channel 111, and the atomizing chamber 114; therefore, the highest point of the first end face 150 is not higher than the lowest point of the atomizing component 200. If the partition 122 can be disposed at the bottom of the atomizing component 200, then the highest point of the first end face A is not higher than the partition 122.

[0065] Here, the lowest point refers to the point where the structure or space is at its smallest vertical distance from the bearing surface B, and the highest point refers to the point where the structure or space is at its largest vertical distance from the bearing surface B. For example, the lowest point of the storage bin 300, the feeding channel 111, the atomizing component 200, and the atomizing chamber 114 refers to the point among the four that is closest to the bearing surface B vertically, and the highest point of the first end face A refers to the point where the first end face A is furthest from the bearing surface B vertically.

[0066] Please see Figure 9 , Figure 10 , Figure 11 , Figure 12 and Figure 13In some embodiments, the overflow volume 500 includes a storage component 510, which is configured to receive at least a portion of the aerosol-generating matrix flowing through the overflow channel 400 when the air pressure inside the storage silo 300 is greater than the external air pressure, and / or return at least a portion of the aerosol-generating matrix to the overflow channel 400 when the air pressure inside the storage silo 300 is less than the external air pressure. The storage component 510 has a porous structure, specifically it can be an inorganic porous material, such as ceramics, porous glass, ceramic foam, glass foam, etc.; it can also be an organic porous material, including but not limited to polymers such as polypropylene (PP), polyester fiber, polylactic acid (PLA) porous materials, natural porous materials such as cotton, wood-derived carbon, etc.; it can also be a composite porous material, such as metal-organic framework (MOF) derived materials, polymer-inorganic hybrid materials such as carbon fiber reinforced polyethylene, etc. The porosity of the porous material can be adjusted according to the composition of the aerosol generating matrix. For example, when the aerosol generating matrix is ​​liquid and has a high viscosity, a porous material with high porosity and liquid conductivity can be selected to make the storage component 510 to ensure the liquid conductivity effect. Alternatively, when the aerosol generating matrix is ​​liquid and has a low viscosity, a porous material with low porosity and liquid conductivity can be selected to make the storage component 510.

[0067] In some embodiments, the atomizing component 200 includes a heating element 210 for heating the aerosol generating matrix to atomize and generate aerosol, and a suction element 220 connected to the heating element 210. The suction element 220 communicates with the feeding channel 111 and is used to draw in the aerosol generating matrix. The suction element 220 has a porous structure. The material of the suction element 220 can be the same as or different from that of the storage component 510. In some embodiments, the porosity of the storage component 510 is greater than that of the suction element 220. The greater porosity of the storage component 510 allows the storage component 510 to absorb or release the aerosol generating matrix more quickly when the air pressure changes. When the volume of the aerosol generating matrix in the storage silo 300 increases and tends to overflow, the storage component 510 has a higher porosity. Therefore, the resistance to the aerosol generating matrix moving towards the storage component 510 is smaller. This means the aerosol generating matrix will preferentially flow towards the storage component 510 when its volume expands, reducing the risk of leakage into the suction component 220 and preventing leakage. The suction component 220 can be an inorganic porous material, such as ceramics, porous glass, ceramic foam, or glass foam; it can also be an organic porous material, including but not limited to polymers such as polypropylene (PP), polyester fiber, and polylactic acid (PLA) porous materials, as well as natural porous materials such as cotton and wood-derived carbon; it can also be a composite porous material, such as metal-organic framework (MOF) derived materials or polymer-inorganic hybrid materials such as carbon fiber reinforced polyethylene. The porosity of the suction element 220 can be adjusted according to the composition of the aerosol generating matrix. For example, when the aerosol generating matrix is ​​liquid and has a high viscosity, a porous material with a high porosity can be used to make the suction element 220 to ensure the liquid guiding effect. Alternatively, when the aerosol generating matrix is ​​liquid and has a low viscosity, a porous material with a low porosity can be used to make the suction element 220. It is only necessary to ensure that the porosity of the storage element 510 is greater than the porosity of the suction element 220.

[0068] like Figure 9 As shown, in some embodiments, the overflow volume 500 may include a storage element 510 but does not include the backflow channel 520 mentioned below.

[0069] Please see Figure 10 , Figure 11 , Figure 12 and Figure 13As shown, in some embodiments, the overflow volume 500 may simultaneously include a storage unit 510 and a backflow channel 520. The backflow channel 520 communicates with the overflow channel 400. The backflow channel 520 is configured to receive at least a portion of the aerosol-generating matrix flowing through the overflow channel 400 when the air pressure inside the storage silo 300 is greater than the external air pressure, and / or return at least a portion of the aerosol-generating matrix to the overflow channel 400 when the air pressure inside the storage silo 300 is less than the external air pressure. The backflow channel 520 can absorb excess liquid when the storage silo 300 is under positive pressure relative to the external environment, and can release stored liquid when the storage silo 300 is under negative pressure relative to the external environment, maintaining system pressure balance.

[0070] For example, such as Figure 10 As shown, in some embodiments, the backflow channel 520 is an opening formed in the storage component 510. Directly opening the storage component 510 to form the backflow channel 520 reduces the number of independent components, and the opening process of the backflow channel 520 is completed simultaneously with the forming of the storage component 510, which helps reduce manufacturing costs. In some embodiments, the backflow channel 520 is a through hole formed in the storage component 510, with its through-direction generally parallel to the axial direction of the atomizer. In other embodiments, the backflow channel 520 may also be a non-through hole, or along a different direction. In some embodiments, the backflow channel 520 is formed inside the storage component 510; in other embodiments, the backflow channel 520 may also be formed on the outer periphery of the storage component 510, such as by a recess on the outer periphery of the storage component, and together with the inner wall of the atomizing seat, constitute the backflow channel 520. Of course, the shape, position and direction of the backflow channel 520 can be changed according to the different shapes of the atomizer. For example, the cross-sectional shape of the backflow channel 520 can be designed as a circle, a square or other geometric shape. There are no restrictions here, but it is within the scope of the concept of this utility model.

[0071] For example, in some embodiments, the backflow channel 520 is an opening formed in the atomizing base 100. The backflow channel 520 is formed by directly opening or slotting in the atomizing base 100, reducing the number of independent components. Furthermore, the opening process of the backflow channel 520 is completed simultaneously with the forming of the atomizing base 100, which helps reduce manufacturing costs. In some embodiments, the backflow channel 520 is a through hole formed in the atomizing base 100, with its through-path generally parallel to the axis of the atomizer. In other embodiments, the backflow channel 520 may also be a non-through hole, or along a different direction. In some embodiments, the backflow channel 520 is formed inside the atomizing base 100. Of course, the shape, position, and direction of the backflow channel 520 can be changed according to different shapes of the atomizer. For example, the cross-sectional shape of the backflow channel 520 can be designed as circular, square, or other geometric shapes. This is not limited here, but is within the scope of the present invention.

[0072] For example, such as Figure 11 As shown, in some embodiments, the overflow volume 500 further includes a hollow back-suction tube 530 that encloses and forms the back-suction channel 520, and the back-suction tube 530 passes through the storage component 510. The back-suction tube 520 can be a stainless steel tube, a plastic tube, etc., and can have the characteristics of corrosion resistance, high temperature resistance, and structural stability. The back-suction tube 530 can also be made of a porous material, and its material can be the same as that of the storage component 510 (such as porous ceramic or fiber cotton), or different from that of the storage component 510 (such as sintered metal or polymer porous material). Of course, the shape, position, and orientation of the back-suction tube 530 can also be changed according to the different shapes of the atomizer. For example, the cross-sectional shape of the back-suction tube 530 can be designed as circular, square, or other geometric shapes; the back-suction tube 530 can be a straight tube or a curved tube, etc. No limitation is made here, but it is still within the scope of the present invention.

[0073] For example, such as Figure 12 As shown, in some embodiments, the atomizing seat 100 has a receiving cavity 123, and the storage component 510 is embedded in the receiving cavity 123. A back suction groove 124 is formed on the cavity wall of the receiving cavity 123, and the groove wall of the back suction groove 124 and the outer peripheral surface of the storage component 510 enclose the back suction channel 520. By directly machining the back suction groove 124 on the cavity wall of the receiving cavity 123 and fitting it with the outer peripheral surface of the storage component 510 to form the back suction channel 520, the number of assembly parts is reduced, the manufacturing cost is lowered, and the compactness and reliability of the overall structure are improved.

[0074] For example, in some embodiments, the atomizing seat 100 is provided with a receiving cavity 123, the storage member 510 is disposed in the receiving cavity 123, and a back suction groove 124 is formed on the outer peripheral surface of the storage member 510. The groove wall of the back suction groove 124 and the cavity wall of the receiving cavity 123 enclose the back suction channel 520. By directly machining the back suction groove 124 on the outer peripheral surface of the storage member 510 and cooperating with the cavity wall of the receiving cavity 123 to form the back suction channel 520, the number of assembly parts is reduced, the manufacturing cost is reduced, and the compactness and reliability of the overall structure are improved.

[0075] For example, such as Figure 13 As shown, in some embodiments, the overflow volume 500 further includes a hollow back suction pipe 530 that encloses the back suction channel 520, the back suction pipe 530 being sandwiched between the cavity wall of the accommodating cavity 123 and the outer peripheral surface of the storage member 510.

[0076] Please see Figure 14 , Figure 15 and Figure 16 In some embodiments, the overflow volume 500 may include a backflow channel 520 but not a storage element 510. The backflow channel 520 communicates with the overflow channel 400 and is configured to receive at least a portion of the aerosol generating matrix flowing through the overflow channel 400 when the air pressure within the storage hopper 300 is greater than the external air pressure, and / or return at least a portion of the aerosol generating matrix to the overflow channel 400 when the air pressure within the storage hopper 300 is less than the external air pressure. The suction force of the backflow channel 520 on the aerosol generating matrix may be greater than the suction force of the suction element 220 of the atomizing component 200 on the aerosol generating matrix. Therefore, when the storage hopper 300 is under positive pressure relative to the outside, the backflow channel 520 can preferentially receive the aerosol generating matrix through the overflow channel 400, preventing the aerosol generating matrix from leaking out from the suction element 220.

[0077] For example, such as Figure 14As shown, in some embodiments, the backflow channel 520 is an opening formed on the atomizing base 100. Directly opening the atomizing base 100 to form the backflow channel 520 reduces the number of independent components, and the opening process of the backflow channel 520 is completed simultaneously with the forming of the atomizing base 100, which helps to reduce manufacturing costs. In some embodiments, the backflow channel 520 is a through hole formed on the atomizing base 100, with its through-direction approximately parallel to the axial direction of the atomizer. In other embodiments, the backflow channel 520 may also be a non-through hole, or along a different direction. In some embodiments, the backflow channel 520 is formed inside the atomizing base 100. Of course, the shape, position, and direction of the backflow channel 520 can also be changed according to different shapes of the atomizer. For example, the cross-sectional shape of the backflow channel 520 can be designed as circular, square, or other geometric shapes; this is not limited here, but is still within the scope of the present invention.

[0078] For example, as shown in Figure 14, in some embodiments, the overflow volume 500 further includes a hollow back-suction tube 530 that encloses and forms the back-suction channel 520. The back-suction tube 520 can be a stainless steel tube, a plastic tube, etc., and can possess characteristics such as corrosion resistance, high temperature resistance, and structural stability. The back-suction tube 530 can also be made of porous materials, such as porous ceramics or fiber cotton. Of course, the shape, position, and orientation of the back-suction tube 530 can be changed according to the different shapes of the atomizer. For example, the cross-sectional shape of the back-suction tube 530 can be designed as circular, square, or other geometric shapes; the back-suction tube 530 can be a straight tube or a curved tube, etc. No limitations are imposed here, but all are within the scope of the present invention.

[0079] For example, in some embodiments, the overflow volume 500 further includes a sealing body, which may be made of a sealing material such as silicone or rubber. In some embodiments, the backflow channel 520 may be formed by a through-hole in the center of the sealing body. In other embodiments, the backflow channel 520 may also be formed by the sealing body and a portion of the inner wall of the atomizing seat, such as the outer periphery of the sealing body being recessed and forming the backflow channel 520 together with a portion of the inner wall of the atomizing seat 100, or a portion of the inner wall of the atomizing seat 100 being recessed and forming the backflow channel 520 together with the sealing body. The sealing body can compensate for the slight deformation of the internal structure of the atomizer 11 caused by temperature or air pressure changes, maintain a tight fit, and avoid gaps caused by thermal expansion and contraction or air pressure fluctuations, thereby preventing outside air from entering the storage chamber 300 and preventing the aerosol generation matrix in the storage chamber 300 from leaking to the outside. Understandably, without a sealing body, when the external temperature or air pressure changes, the tight fit between the internal structures of the atomizer 11 may fail and gaps may be created, making it easy for external gas to enter the storage chamber 300, or for the aerosol generation matrix to leak.

[0080] like Figure 4 As shown, in some embodiments, the feeding channel 111 includes a first feeding space 1111 communicating with the storage bin 300 and a second feeding space 1112 communicating with the first feeding space 1111. The second feeding space 1112 is communicating with the atomizing component 200. The top of the atomizing seat 100 is provided with an air outlet 113. The atomizing seat 100 is provided with an atomizing chamber 114. The atomizing chamber 114 is located below the air outlet 113 and communicates with the air outlet 113. The atomizing component 400 is disposed in the atomizing chamber 114, that is, the atomizing component 200 is located below the air outlet 113 and communicates with the air outlet 113. A partition 122 is formed within the atomizing seat 100. The partition 122 is located on the side of the atomizing component 200 away from the air outlet 113 and is spaced apart from the atomizing component 200 to form the second feeding space 1112. The overflow volume 500 is located on the side of the second feeding space 1112 away from the atomizing component 200. Under the influence of gravity, the aerosol generating matrix tends to flow towards the lower overflow volume 500, which is more conducive to the preferential absorption of the aerosol generating matrix by the overflow volume 500 when the air pressure in the storage bin 300 is greater than the external air pressure.

[0081] like Figure 16As shown, in some embodiments, the atomizer 11 further includes a guide member 600 disposed within the second feeding space 1112. The guide member 600 may be a porous structure, the porosity of the storage member 510 is greater than the porosity of the guide member 600, and the porosity of the guide member 600 is greater than the porosity of the suction member 220. Porosity refers to the ratio of the total volume of tiny voids within a porous medium to the total volume of the porous medium. For example, the guiding component 600 can be a porous material such as cotton, ceramic, or glass. The porosity of the porous material can be adjusted according to the composition of the aerosol generating matrix. For example, when the aerosol generating matrix is ​​liquid and has a high viscosity, a porous material with a high porosity can be selected to make the suction component 220 and the storage component 510 to ensure the liquid guiding effect. Or, when the aerosol generating matrix is ​​liquid and has a low viscosity, a porous material with a low porosity can be selected to make the suction component 220 and the storage component 510. It is only necessary to satisfy that the porosity of the storage component 510 is greater than that of the guiding component 600 and the porosity of the guiding component 600 is greater than that of the suction component 220. The porosity of the guide component 600 is greater than that of the suction component 220. This allows it to absorb the aerosol generating matrix from the second feeding space 1112 more quickly, while also slowing down the flow of the aerosol generating matrix using its own structure. This prevents the aerosol generating matrix from being absorbed too quickly by the suction component 220, reducing the risk of the aerosol generating matrix seeping out from the suction component 220. During the process of the heating element 210 heating the aerosol generating matrix to form an aerosol, the aerosol generating matrix in the suction component 220 may undergo certain property changes due to the heat. The guide component 600 can also reduce the backflow of the aerosol generating matrix that has undergone property changes in the suction component 220, thereby ensuring the cleanliness of the aerosol generating matrix in the feeding channel 111, storage bin 300, overflow channel 400, and overflow volume 500.

[0082] like Figure 4As shown, in some embodiments, the atomizing seat 100 is provided with a collection chamber 150 communicating with the air inlet 131. One end of the overflow volume 500 is connected to the collection chamber 150, and the collection chamber 150 is used to contain the aerosol generating matrix from the overflow volume 500. The other end of the overflow volume 500 is connected to the feeding channel 111. The collection chamber 150 is connected to the outside through the air inlet 131. When the air pressure in the storage bin 300 is greater than the outside air pressure, the aerosol generating matrix can flow into the collection chamber 150 through the overflow channel 400 and the overflow volume 500. The collection chamber 150 can also return the aerosol generating matrix in the collection chamber 150 to the feeding channel 111 or the storage bin 300 through the overflow channel 400 when the air pressure in the storage bin 300 is less than the outside air pressure. The collection chamber 150 can increase the collection space for aerosol generation matrix, and can also increase the temporary storage and regulation capacity of the overflow volume 500 for aerosol generation matrix when the air pressure in the storage silo 300 changes, thus maintaining the air pressure balance between the storage silo 300 and the outside.

[0083] like Figure 4 and Figure 7 As shown, in some embodiments, the atomizing seat 100 includes a first atomizing seat 110, a second atomizing seat 120 detachably connected to the lower part of the first atomizing seat 110, and a bottom cover 130. The first atomizing seat 110 has a feed hole 112 at its top. The atomizing component 200 is disposed in the first atomizing seat 110. The first atomizing seat 110 has a feeding channel 111. The second atomizing seat 120 has a partition 122 at its top. The bottom cover 130 is embedded in the bottom of the second atomizing seat 120 and forms the collecting cavity 150 with the partition 122 and the inner surface of the second atomizing seat 120. The bottom cover 130 has an air inlet 131. In this configuration, the partition 122 is disposed on the second atomizing seat 120, and the partition 122 isolates the overflow volume 500 from the atomizing assembly 200, the feeding channel 111, and the storage bin 300. In other embodiments, the atomizing seat 100 may also be a one-piece molded structure.

[0084] like Figure 4 and Figure 8As shown, in some embodiments, the bottom cover 130 has a baffle portion 133 on the side facing the partition 122. The baffle portion 133 is arranged around the periphery of the air inlet 131, and the outer peripheral surface of the baffle portion 133, together with the inner surfaces of the bottom cover 130 and the second atomizing seat 120, forms the collection chamber 150. The baffle portion 133 surrounding the air inlet 131 can form a physical barrier, preventing the aerosol generation matrix in the collection chamber 150 from leaking from the air inlet 131.

[0085] like Figure 8 As shown, in some embodiments, the bottom cover 130 is provided with a capillary channel 134 on the side facing the partition 122, and the capillary channel 134 is connected to the overflow volume 500. When the overflow volume 500 needs to return the aerosol generating matrix to the overflow channel 400, the capillary channel 134 can use capillary action to guide the residual liquid of the aerosol generating matrix in the collection chamber 150 to the overflow volume 500, avoiding liquid accumulation in the collection chamber 150.

[0086] like Figure 4 and Figure 7 As shown, in some embodiments, the atomizing seat 100 further includes a first sealing member 141. A first sealing groove 121 is formed on the outer peripheral surface of the second atomizing seat 120. The first sealing member 141 is embedded in the first sealing groove 121 and seals against the groove wall of the first sealing groove 121 and the inner surface of the first atomizing seat 110. The first sealing member 141, embedded in the first sealing groove 121, ensures a tight fit between the second atomizing seat 120 and the first atomizing seat 110, preventing external air infiltration or leakage of the internal aerosol generation matrix. The first sealing groove 121 can be used to fix the first sealing member 141. It is understood that the size of the first sealing groove 121 can be slightly smaller than the first sealing member 141, so that the first sealing member 141, when compressed, tightly fits against the groove wall of the first sealing groove 121, enhancing the sealing performance. The first sealing member 141 may include, but is not limited to, a sealing ring, a silicone gasket, etc.

[0087] like Figure 4 and Figure 7As shown, in some embodiments, the atomizing seat 100 further includes a second sealing member 142. A second sealing groove 132 is formed on the outer peripheral surface of the bottom cover 130. The second sealing member 142 is embedded in the second sealing groove 132 and seals against the groove wall of the second sealing groove 132 and the inner surface of the second atomizing seat 120. The second sealing member 142, embedded in the second sealing groove 132, ensures a tight fit between the second atomizing seat 120 and the bottom cover 130, preventing external air infiltration or leakage of the internal aerosol generation matrix. The second sealing groove 132 can be used to fix the second sealing member 142. It is understood that the size of the second sealing groove 132 can be slightly smaller than the second sealing member 142, so that the second sealing member 142, when compressed, tightly fits against the groove wall of the second sealing groove 132, enhancing the sealing performance. The second sealing member 142 may include, but is not limited to, sealing rings, silicone gaskets, etc.

[0088] In some embodiments, the overflow channel 400 may be an opening formed in the storage silo 300 or the feeding channel 111. In other embodiments, the overflow channel 400 may also be a separate structural component, such as a pipe, which communicates with the storage silo 300 or the feeding channel 111.

[0089] like Figure 4 As shown, in some embodiments, the atomizer 11 further includes a battery assembly 700, which is electrically connected to the atomizing assembly 200 and provides power to the atomizing assembly 200. The battery assembly 700 includes electrode posts 710 passing through the second atomizing base 120 and the bottom cover 130. One end of the electrode post 710 is electrically connected to the heating element 210 of the atomizing assembly 200, and the other end of the electrode post 710 is exposed on the outer surface of the atomizer 11 and is used for electrical connection to the power supply assembly 12.

[0090] like Figure 3 As shown, in some embodiments, the atomizer 11 further includes a housing 800, the atomizing base 100 is embedded in the bottom of the housing 800, and the storage chambers 300 are all disposed within the housing 800 and above the atomizing base 100. The top surface of the atomizing base 100 and the inner surface of the housing 800 enclose the storage chamber 300. This structural design can be considered as the top surface of the atomizing base 100 and the inner surface of the housing 800 directly forming the storage chamber 300, reducing the number of parts, lowering costs, and improving assembly efficiency. Figure 4 and Figure 7As shown, in some embodiments, the atomizing seat 100 further includes a first sealing gasket 171 and a second sealing gasket 172. The first sealing gasket 171 seals against the inner surface of the housing 800 and the first atomizing seat 110 to prevent the aerosol generating matrix from leaking from the gap between the housing 800 and the first atomizing seat 110. The second sealing gasket 172 abuts against the inner wall of the atomizing chamber 114 and the suction member 220 to prevent the aerosol generating matrix from leaking from the gap between the inner wall of the atomizing chamber 114 and the suction member 220, and can also prevent condensate or gas in the atomizing chamber 114 from leaking into the atomizing seat 100.

[0091] In other embodiments, the atomizer 11 further includes a housing 800, the atomizing seat 100 is embedded in the bottom of the housing 800, and the storage chambers 300 are all disposed within the housing 800 and above the atomizing seat 100. The inner walls of the storage chambers 300 enclose a storage cavity for loading the aerosol generating matrix. This structural design can be considered as the storage component 510 being a separate structural part, the storage chambers 300 being separately disposed within the housing 800, and the inner walls of the storage chambers 300 independently enclosing a storage cavity.

[0092] like Figure 5 and Figure 6 As shown, in some embodiments, the atomizing base 100 is provided with a first air passage 161, a second air passage 162, and a third air passage 163 connected in sequence. The first air passage 161 communicates with the air inlet 131, and the third air passage 163 communicates with the air outlet 113 through the atomizing chamber 114. The first air passage 161 and the third air passage 163 can be openings provided on the side peripheral surface of the atomizing base 100, and the second air passage 162 can be formed by the side peripheral surface of the atomizing base 100 and the outer shell 800. Specifically, the first air passage 161, the second air passage 162, and the third air passage 163 can be distributed sequentially from bottom to top along the axial direction of the atomizing base 100. More specifically, the first air passage 161 and the third air passage 163 can be openings provided on the side peripheral surface of the first atomizing seat 110, and the second air passage 162 can be formed by the side peripheral surface of the first atomizing seat 110 and the outer shell 800. Figure 5 The dotted line with a single arrowhead can be considered as a schematic diagram of the direction of airflow from the outside into the atomizer 11 through the atomizing assembly 200. The outside air can flow into the atomizing chamber 114 through the air inlet 131, the first air passage 161, the second air passage 162, and the third air passage 163, and then brush against the atomizing surface of the atomizing assembly 200. The atomizing surface of the atomizing assembly 200 can be considered as the side that atomizes the aerosol generation matrix to form an aerosol. For example, in... Figure 5In the illustrated embodiment, the bottom surface of the suction element 220 contacts the aerosol generating matrix of the feeding channel 111 and is used to draw the aerosol generating matrix to the heating element 210. The heating element 210 is connected to the suction element 220 and at least part of the heating element 210 is exposed above the suction element 220. This can be considered as a structural design for the atomizing component 200 to atomize upwards. More specifically, the third air passage 163 is located at a position higher than or equal to the atomizing component. It can be considered that the air entering through the third air passage 163 passes through at least part of the heating element 210 exposed above the suction element 220, thereby carrying aerosol and being discharged from the air outlet 113 and drawn in by the user. For example, in another embodiment, the suction element 220 may be a top or side surface used to suction the aerosol generation matrix, while the heating element 210 is connected to the suction element 220 and at least partially exposed below the suction element 220. This can be considered a downward atomization structural design of the atomizing assembly 200. In yet another embodiment, the heating element 210 may be connected to the suction element 220 and at least partially exposed on the outer periphery of the suction element 220. This can be considered as the atomizing surface of the atomizing assembly 200 being on the side or even slightly inclined relative to the axial direction of the atomizing assembly. Both of these can be considered as a lateral atomization structural design of the atomizing assembly 200.

[0093] In addition, such as Figure 1 As shown, this application also provides an electronic atomizing device 10, which includes a power supply component 12 and an atomizer 11 as described in any of the above embodiments. The power supply component 12 is electrically connected to the atomizing component 200 and provides energy to the atomizing component 200.

[0094] Since the aforementioned electronic atomizing device 10 includes the atomizer 11 described in any of the above embodiments, the electronic atomizing device 10 also has at least the following beneficial effects: the overflow volume 500 of the atomizer 11 has an automatic adjustment function, which can absorb excess aerosol generating matrix when the storage chamber 300 is under positive pressure relative to the outside, and return the aerosol generating matrix when the storage chamber 300 is under negative pressure relative to the outside, maintaining system pressure balance. In other words, the overflow volume 500 plays a buffering and temporary storage role in the delivery of the aerosol generating matrix. Without additional power or complex control mechanisms, it can effectively cope with the volume changes of the aerosol generating matrix in the storage chamber 300 caused by temperature or air pressure fluctuations, ensuring the stable operation of the atomizer 11 under different environmental conditions. It has a simple structure, low cost, and high reliability. The aerosol generating matrix can be a liquid. Specifically, when the air pressure inside the storage chamber 300 is greater than the external air pressure, the overflow volume 500 can contain the aerosol generating matrix flowing in from the overflow channel 400, preventing the aerosol generating matrix from leaking out of the atomizing component 200 and avoiding leakage problems. When the air pressure inside the storage chamber 300 decreases, the aerosol generating matrix in the overflow volume 500 can automatically flow back to the storage chamber 300 or the supply channel 111 through the overflow channel 400, ensuring a continuous liquid supply to the atomizing component 200 and avoiding dry burning problems caused by insufficient liquid supply. Understandably, if the overflow volume 500 is not set, when the air pressure inside the storage chamber 300 increases, the expanding gas will directly squeeze the aerosol generating matrix towards the atomizing component 200, causing liquid to leak out. When the air pressure inside the storage chamber 300 decreases, it may lead to insufficient liquid supply and the risk of dry burning. The power supply component 12 can provide power to the atomizing component 200 of the atomizer 11, so that the atomizing component 200 atomizes the aerosol generating matrix to generate an aerosol that can be inhaled by the user.

[0095] like Figure 17 As shown, in some embodiments, the power supply assembly 12 is provided with a mounting slot 13 for inserting the atomizer 11, and the distance d1 between the bottom of the atomizer 11 and the partition 122 is not less than the depth d2 of the mounting slot 13. In other words, when the atomizer 11 is inserted into the mounting slot 13, the distance d1 between the partition 122 of the atomizer 11 and the bottom of the mounting slot 13 is not less than the depth d2 of the mounting slot 13. With the distance d1 between the bottom of the atomizer 11 and the partition 122, the overflow volume 500, such as the collection chamber 150, can have a larger capacity, thereby accommodating more aerosol generating matrix and better reducing the risk of aerosol generating matrix seeping out from the atomizing assembly 200.

[0096] In some embodiments, the electronic atomizing device 10 can be a split-type electronic atomizing device. In other words, the aerosol generating device 10 can be considered a replaceable aerosol generating device, where the atomizer 11 can be detachably connected to the power supply component 12, allowing the user to replace either the atomizer 11 or the power supply component 12 as needed. For example, when the aerosol generating matrix in the atomizer 11 is depleted, a new atomizer 11 containing the aerosol generating matrix can be selected for replacement. Similarly, if the power supply component 12 has insufficient power or is damaged, another power supply component 12 with sufficient power or normal operation can be selected for replacement.

[0097] In some embodiments, the electronic atomizing device 10 can be an integrated electronic atomizing device, that is, the atomizer 11 is fixedly connected to the power supply component 12.

[0098] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0099] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
