[0025] The serial numbers assigned to components herein, such as "first," "second," etc., are used solely to distinguish the objects being described and do not convey any sequential or technical meaning. References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).

[0026] The present application provides an atomizer 100 and an atomizing device, wherein please refer to Figure 1-3 The atomizer 100 includes a housing 110 , a nozzle 120 , a first liquid storage chamber 130 , and an atomizing assembly 140 .

[0027] Please refer to Figure 2The housing 110 has a mounting cavity 111, the nozzle 120 is located at the first end of the housing 110, and the first liquid storage cavity 130 and the nozzle 120 are located at the same end of the housing 110. The first liquid storage cavity 130 is used to store a liquid aerosol-generating matrix. The first liquid storage cavity 130 has a liquid outlet 131, and the liquid outlet 131 is arranged on the side away from the first end. The atomization assembly 140 is arranged in the mounting cavity 111. The atomization assembly 140 includes a liquid guide 141 and a heating element 142 arranged near the liquid guide 141. The heating element 142 is used to heat the atomized aerosol-generating matrix. The atomized aerosol can be sucked out through the nozzle 120. A buffer space 112 is provided between the liquid outlet 131 and the liquid guide 141. The liquid outlet 131 is configured to deliver the aerosol-generating matrix to the liquid guide 141 at a predetermined rate.

[0028] When facing changes in high and low temperatures and air pressure, the aerosol-generating matrix in the first liquid storage chamber 130 can enter the buffer space 122 at a predetermined rate without leakage, and the aerosol-generating matrix in the buffer space 122 can be atomized and utilized without waste.

[0029] Figure 1-3 Only a portion of the structure of the atomizer device of this embodiment is shown, with the power supply, control components, etc. omitted. In one exemplary operating mode, a user draws on the nozzle 120, generating a negative pressure within the housing 110. The control component (not shown) determines based on the negative pressure that the user is taking a puff, and thereby controls the power supply (not shown) to supply power to the atomizer assembly 140.

[0030] Another exemplary working mode is that a key switch (not shown) is provided on the housing 110 , and the control component controls the power supply to supply power to the atomizing component 140 in response to the key switch being triggered.

[0031] Another exemplary working mode is that the control component is started based on a specific action or a specific posture. For example, shaking the atomizer device for 1 second, or flipping the atomizer device twice within 2 seconds, the control component can identify the specific action or posture based on sensor elements such as a gyroscope, thereby controlling the power supply to supply power to the atomizer component 140. An exemplary power supply time is 2-4 seconds.

[0032] The predetermined rate refers to a low flow rate, the purpose of which is to make the output rate of the aerosol-generating substrate from the liquid outlet 131 comparable to the consumption rate of the aerosol-generating substrate when the nebulizer 100 is in use, so that the liquid-guiding member 141 is less likely to be oversaturated with liquid, thereby avoiding leakage.

[0033] For example, for the first liquid storage chamber 130 with a volume of 10 ml, the predetermined rate may be such that after the first liquid storage chamber 130 is independently separated and, in a naturally inverted state, the aerosol-generating matrix in the first liquid storage chamber 130 can basically flow out of the first liquid storage chamber 130 within 15-45 minutes.

[0034] For example, for the first liquid storage chamber 130 with a volume of 20 ml, the predetermined rate may be that after the first liquid storage chamber 130 is independently separated, in a natural inverted state, the aerosol-generating matrix in the first liquid storage chamber 130 can basically flow out of the first liquid storage chamber 130 within 30-90 minutes.

[0035] For example, when selecting first liquid storage chambers 130 with different volumes, the time for the aerosol generating substrate to flow out of the first liquid storage chamber 130 may be different. However, under the premise that the predetermined rate remains substantially unchanged, the volume and time are positively correlated.

[0036] In one embodiment, the liquid-conducting member 141 is made of a porous material, such as plant fiber, sponge, cellulose acetate, porous ceramics, or metal foam. The capillary force generated by the porous structure of the liquid-conducting member 141 allows the aerosol-generating substrate to be transferred from a high-concentration portion to a low-concentration portion. The liquid-conducting member 141 also has a certain volume, which can be configured to store 1-4 ml of liquid aerosol-generating substrate, such as 1 ml, 2 ml, 3 ml, or 4 ml.

[0037] In one embodiment, the buffer space 112 is as follows: Figure 2 As shown, the cavity is formed by the gap between the first liquid storage cavity 130 and the liquid guide 141. The circumference of the buffer space 112 is surrounded by the outer wall of the shell 110. Therefore, the circumference of the buffer space 112 is sealed. Figure 2 The upper portion is shown connected to the first liquid storage chamber 130, and the lower portion is connected to the liquid guide 141. After flowing out of the first liquid storage chamber 131, the aerosol-generating substrate first passes through the buffer space 112, which prolongs the flow path and flow time of the aerosol-generating substrate to the liquid guide 141. Furthermore, the aerosol-generating substrate in the first liquid storage chamber 130 is not affected by the capillary force of the liquid guide 141, ensuring that the predetermined rate in the aforementioned embodiment is stable.

[0038] In one embodiment, reference Figure 2 The communication between the buffer space 112 and the liquid guiding member 141 is achieved through one or more through holes 151. Under the premise that the number of through holes 151 is consistent, the rate at which the aerosol generating matrix flows out of the buffer space 112 is also basically set, thereby further extending the flow path and flow time of the aerosol generating matrix to the liquid guiding member 141.

[0039] The buffer space 112 is designed to, firstly, extend the flow path and flow time of the aerosol-generating matrix to the liquid-guiding member 141; and secondly, to prevent the aerosol-generating matrix in the first liquid storage chamber 130 from being affected by the capillary force of the liquid-guiding member 141, so that the predetermined rate at which the aerosol-generating matrix flows out of the first liquid storage chamber 130 is stable.

[0040] In one embodiment, the buffer space 112 has a preset volume. When matching the first liquid storage chamber 130 with a volume of 10 ml, the preset volume is 3-5 ml, for example, 3 ml, 3.5 ml, 4 ml, 4.5 ml, or 5 ml.

[0041] In one embodiment, when the buffer space 112 matches the first liquid storage chamber 130 with a volume of 20 ml, the preset volume is 4-9 ml, for example, 4 ml, 5 ml, 6 ml, 7 ml, 8 ml, and 9 ml.

[0042] The 10 ml or 20 ml volume of the first liquid storage chamber 130 mentioned in the above two embodiments refers to the volume of the aerosol-generating substrate contained therein, rather than the volume specification of the first liquid storage chamber 130. 10 ml and 20 ml are two common volume specifications, but the volume specifications of the containers (i.e., the first liquid storage chamber 130) used by different manufacturers are not uniform.

[0043] In one embodiment, the first liquid storage chamber 130 and the mouthpiece 120 are disposed at the same end of the housing 110, and the liquid outlet 131 of the first liquid storage chamber 130 is disposed on a side facing away from the first end. When the nebulizer 100 is placed upright, the aerosol-generating substrate in the first liquid storage chamber 130 flows out of the first liquid storage chamber 130 to the liquid guide 141 solely by gravity, which is in line with user habits. The user does not need to invert the nebulizer 100 to complete the filling of the liquid guide 141, or use special operations such as shaking to complete the filling, which is convenient to operate.

[0044] In one embodiment, please refer to Figure 2 , along the direction in which the aerosol is inhaled (i.e. Figure 2 ), the first liquid storage chamber 130 is arranged downstream of the liquid guiding member 141.

[0045] The first liquid storage chamber 130 is arranged downstream of the liquid guide 141. When the atomizer 100 is placed upright (i.e. Figure 2 As shown in the state shown in FIG, the aerosol generating substrate automatically drips onto the liquid guiding member 141 under the influence of gravity.

[0046] In one embodiment, the first liquid storage chamber 130 is positioned upstream of the liquid guide 141 (not shown) along the direction in which the aerosol is drawn out. In this design, the atomizer assembly 140 and the first liquid storage chamber 130 are arranged along the length of the atomizer device, resulting in a rod-shaped overall shape consistent with mainstream commercially available products. On the other hand, when the atomizer device employing this design is positioned with the nozzle 120 facing upward, the aerosol-generating substrate stored in the first liquid storage chamber 130 cannot flow to the liquid aspirating member 141, requiring the atomizer device to be inverted to complete the liquid guide process.

[0047] In one embodiment, please refer to Figure 2 The first liquid storage chamber 130 and the buffer space 112 are arranged in sequence along the length direction of the atomization device, and the first liquid storage chamber 130 and the installation chamber 111 are arranged side by side in the width direction of the atomization device. The side of the buffer space 112 away from the first liquid storage chamber 130 is connected to the installation chamber 111, which facilitates the aerosol generation matrix in the first liquid storage chamber 130 to be guided to the liquid guide member 141 in the installation chamber 111.

[0048] In one embodiment, please refer to Figure 2-3 The liquid outlet 131 also includes a flow limiting member 132, which is attached to the liquid outlet 131 and has a crack 1321 with a variable area. The area change of the crack 1321 responds to at least one of the suction force, the air pressure in the buffer space 112, the buoyancy of the liquid in the buffer space 112, the gravity of the liquid in the first liquid storage chamber 130 and the air pressure in the first liquid storage chamber 130.

[0049] In one embodiment, the flow restrictor 132 is normally closed in the non-suction state, and the airflow of the buffer space 112 and the suction nozzle 120 is connected (not shown). When the user suctions, the buffer space 112 presents a negative pressure change, so that the flow restrictor 132 opens in response to the negative pressure caused by the suction force. In order to make the flow restrictor 132 normally closed in the non-suction state and able to automatically reset, the flow restrictor 132 can be Figure 2 The silicone piece shown has a slit 1321 .

[0050] In one embodiment, Figure 2 As shown, in the initial state (i.e., the factory-shipped state), the buffer space 112 is filled with a predetermined amount of gas, resulting in a high air pressure within the buffer space 112, thereby preventing the flow restrictor 132 from deforming. At this point, the air pressure within the buffer space 112 and the gravity of the liquid aerosol-generating substrate within the first liquid storage chamber 130 reach a state of equilibrium, preventing the flow restrictor 132 from deforming. A pressure relief hole (not shown) may be provided in the buffer space 112. When the user opens the pressure relief hole, high-pressure gas overflows from the buffer space 112, allowing the liquid aerosol-generating substrate to be transferred from the first liquid storage chamber 130 to the liquid guide 141.

[0051] In one embodiment, a predetermined amount of gas is initially drawn from the first liquid storage chamber 130. This creates a negative pressure differential between the air pressure within the first liquid storage chamber 130 and the ambient atmospheric pressure. This negative pressure differential prevents the flow restrictor 132 from deforming. To maintain this negative pressure differential, a sealing film (not shown) can be attached to the surface of the flow restrictor 132. When the user removes the sealing film, the negative pressure differential disappears, allowing the liquid aerosol-generating substrate to be transferred from the first liquid storage chamber 130 to the liquid guide 141.

[0052] In one embodiment, by providing a slit 1321 on the flow-limiting member 132, whether the aerosol-generating matrix continues to flow out of the first liquid storage chamber 130 can be controlled based on the parameters in the buffer space 112 and the first liquid storage chamber 130, thereby optimizing the structure of the nebulizer 100 and preventing the aerosol-generating matrix from leaking from the liquid storage member when the aerosol-generating matrix on the liquid storage member is oversaturated.

[0053] Please refer to Figure 3 The flow restrictor 132 includes a valve 1322 and has at least one slit 1321. The base of the valve 1322 forms a complete circle. When deformed, there are small gaps between the slits 1321. Therefore, after the flow restrictor 132 recovers its shape, the flow restrictor 132 completely blocks the flow of liquid or significantly restricts the flow of liquid. In other words, the first liquid storage chamber 130 is sealed or tends to be sealed.

[0054] The valve 1322 is provided to facilitate the opening and closing of the slit 1321. The flow limiting member 132 can be directly formed by stamping or hot pressing a complete silicone member using a mold. Figure 2 , the flow limiting member 132 is protruded toward the liquid outlet direction and can be formed by hot pressing; please refer to Figure 3 The cracks 1321 are multiple straight cracks 1321, and are arranged on the flow limiting member 132 in a circular radial manner. This arrangement can be formed by mold stamping or hot pressing.

[0055] Please refer to Figure 2 The valve 1322 is formed to bulge in the direction of liquid outflow. Specifically, it is an arc-shaped structure. When the aerosol generating substrate flows out from the first liquid storage chamber 130, the arc-shaped structure of the valve 1322 helps the aerosol generating substrate flow to the slit 1321. Moreover, the deformed valve 1322 is closer to the bottom surface of the buffer space 112. When a small amount of aerosol generating substrate is stored in the buffer space 112, the buoyancy generated by the liquid aerosol generating substrate prompts the valve 1322 to restore its deformation. Figure 2 Detailed description.

[0056] Please refer to Figure 2In one embodiment, when the atomizer 100 is placed upright (i.e., the mouthpiece 120 is facing upward), the aerosol-generating substrate in the first liquid storage chamber 130 can flow to the liquid outlet 131 under the action of its own gravity, and can flow out from the slit 1321 of the flow-limiting member 132 and flow into the buffer space 112, and then flow from the buffer space 112 to the liquid guide member 141. When the aerosol-generating substrate absorbed by the liquid guide member 141 reaches saturation, the aerosol-generating substrate in the buffer space 112 gradually increases until the aerosol-generating substrate in the buffer space 112 contacts the valve 1322 of the flow-limiting member 132. The valve 1322 is acted upon by the buoyancy of the aerosol-generating substrate, and when the gravity of the aerosol-generating substrate in the first liquid storage chamber 130 is equal to the force of the buoyancy, the valve 1322 closes, closing the slit 1321 and preventing the aerosol-generating substrate from flowing out. After the heating element 142 heats and atomizes the aerosol-generating matrix on the liquid-guiding element 141, the aerosol-generating matrix on the liquid-guiding element 141 decreases, and the aerosol-generating matrix in the buffer space 112 can flow into the liquid-guiding element 141 again. The buoyancy of the valve 1322 decreases, and the slit 1321 opens. The aerosol-generating matrix in the first liquid storage chamber 130 can flow from the first liquid storage chamber 130 to the buffer space 112, and then flow from the buffer space 112 into the liquid-guiding element 141. By setting the flow-limiting element 132 and the buffer space 112, when there is sufficient aerosol-generating matrix in the first liquid storage chamber 130, it can be ensured that there is sufficient aerosol-generating matrix on the liquid-guiding element 141, thereby preventing the heating element 142 from sticking. At the same time, due to the setting of the flow-limiting element 132, it can prevent excessive aerosol-generating matrix from flowing into the liquid-guiding element 141, thereby causing the aerosol-generating matrix on the liquid-guiding element 141 to leak.

[0057] In one embodiment, when the atomizer 100 is placed upright, the aerosol-generating substrate in the first liquid storage chamber 130 can flow to the liquid outlet 131 under the action of its own gravity, and can flow out of the slit 1321 of the flow-restricting member 132, flow into the buffer space 112, and then flow from the buffer space 112 to the liquid guide member 141. During this process, the air pressure in the first liquid storage chamber 130 will decrease. When the air pressure in the first liquid storage chamber 130 is lower than the air pressure in the buffer space 112, the aerosol-generating substrate will no longer flow out. However, after the heater 142 heats the aerosol-generating substrate on the liquid guide member 141, a gap is formed in the liquid guide member 141, and the aerosol-generating substrate in the buffer space 112 flows to the liquid guide member 141. The air pressure in the buffer space 112 decreases, the slit 1321 opens, and the aerosol-generating substrate flows out of the first liquid storage chamber 130. In this way, on the one hand, it can ensure that there is enough aerosol generating matrix adsorbed in the liquid guiding member 141 to prevent the heating member 142 from sticking to the core. On the other hand, it can prevent the aerosol generating matrix from leaking from the liquid guiding member 141 when too much aerosol generating matrix is ​​adsorbed on the liquid guiding member 141.

[0058] Please refer to Figure 2 In one embodiment, the flow restrictor 132 extends from the liquid outlet 131 to between the outer wall of the liquid outlet 131 and the inner wall of the buffer space 112. The outer wall of the liquid outlet 131 and the inner wall of the buffer space 112 are interference-fitted by the flow restrictor 132. The flow restrictor 132 provides a seal around the liquid outlet 131 and the buffer space 112. The flow restrictor 132 can be made of rubber or silicone. The flow restrictor 132 seals the buffer space 112 and the first liquid storage chamber 130, preventing the aerosol-generating substrate from leaking out of the gap between the first liquid storage chamber 130 and the buffer space 112 when the nebulizer 100 is inverted or tilted at a certain angle.

[0059] Please refer to Figure 2 The nebulizer 100 further includes a porous plate 150. The porous plate 150, the first liquid storage chamber 130, and the housing 110 define a buffer space 112. The porous plate 150 is provided with at least one through-hole 151, so that the aerosol-generating substrate in the buffer space 112 can flow to the liquid guide 141 through the through-hole 151. The purpose of providing the porous plate 150 is to slow the transfer rate of the aerosol-generating substrate to the liquid guide 141, so that the buffer space 112 can further temporarily store the aerosol-generating substrate in the airway, thereby preventing oversaturation of the liquid guide 141.

[0060] In the present application, a plurality of through holes 151 are provided on the porous plate 150, and the plurality of through holes 151 are dispersedly arranged, which helps to uniformly flow the aerosol generating matrix in the buffer space 112 to the liquid guiding member 141. By setting the number and aperture of the through holes 151, the transfer rate of the aerosol generating matrix from the buffer space 112 to the liquid guiding member 141 can be adjusted.

[0061] Please refer to Figure 2 The first liquid storage chamber 130 is an independent liquid storage container, which can be detachably mounted on the housing 110 , and when the first liquid storage chamber 130 and the atomizing device are assembled together, the first liquid storage chamber 130 can be communicated with the buffer space 112 .

[0062] The liquid storage container is removably mounted on the housing 110, making it easy to replace the liquid storage container and allowing other electronic components in the atomizer 100 to be recycled, saving resources and reducing user costs. Furthermore, the first liquid storage chamber 130 is independently packaged in the shipping state, eliminating the risk of leakage during product transportation.

[0063] In one embodiment, please refer to Figure 2The liquid storage container includes a container body and a liquid outlet pipe. A liquid outlet 131 is disposed within the liquid outlet pipe, allowing the container body to leak out of the buffer space 112, facilitating disassembly and installation of the liquid storage container. The liquid outlet pipe is a protrusion (not labeled) on the liquid storage container. Both sides of this protrusion mate with the flow restrictor 132, and the height of the protrusion is substantially the same as that of the flow restrictor 132. This facilitates forming a multi-layer sealing structure around the periphery of the flow restrictor 132, preventing liquid from leaking from the buffer space 112.

[0064] In one embodiment, in order to expand the capacity of the first liquid storage chamber 130 , the first liquid storage chamber 130 can be arranged to surround the lower end of the suction nozzle 120 . At the same time, the first liquid storage chamber 130 is still arranged parallel to part of the mounting chamber 111 in the radial direction of the mounting chamber 111 .

[0065] In one embodiment, please refer to Figure 2 The liquid guiding member 141 is disposed on a side of the porous plate 150 away from the buffer space 112 , and a portion of the liquid guiding member 141 is disposed in contact with the porous plate 150 and covers the through-holes 151 .

[0066] Liquid-guiding member 141 is positioned against porous plate 150, covering through-holes 151. This allows the aerosol-generating substrate to flow directly onto liquid-guiding member 141 after exiting the buffer space. Due to the fluid flow characteristics of liquids, if there is a gap between liquid-guiding member 141 and porous plate 150, the aerosol-generating substrate flowing in through through-holes 151 may adhere to the bottom wall of porous plate 150. This may also cause the aerosol-generating substrate to leak from the connection between the cavity of liquid-guiding member 141 and bracket 160.

[0067] In one embodiment, in order to further eliminate the risk of leakage of the aerosol generating substrate, the liquid guiding member 141 is configured to substantially fill the cavity in which it is located.

[0068] In one embodiment, please refer to Figure 2 The atomizer 100 further includes a bracket 160, which is disposed in the mounting cavity 111, and the bracket 160, the side wall of the mounting cavity 111 and the porous plate 150 define a second liquid storage cavity 1111 ( Figure 2 The liquid guide 141 and the heating element 142 are arranged in the second liquid storage chamber 1111, and the liquid guide 141 surrounds the heating element 142. Figure 3 The bracket 160 includes an upper bracket 161 and a lower bracket 162. The upper bracket 161 and the lower bracket 162 are relatively arranged in the mounting cavity 111 along the axial direction of the mounting cavity 111, and the upper bracket 161 is arranged flush with the porous plate 150 in the radial direction of the mounting cavity 111.

[0069] refer to Figure 3By arranging an upper bracket 161 and a lower bracket 162 in the installation cavity 111, the upper bracket 161, the lower bracket 162, the porous plate 150 and the side wall of the installation cavity 111 enclose a second liquid storage cavity 1111, which can further prevent the aerosol-generating matrix from leaking from the second liquid storage cavity 1111, thereby damaging other electronic components, such as the aforementioned power supply or control components.

[0070] In one embodiment, please refer to Figure 2 Second liquid storage chamber 1111 is radially extending through mounting chamber 111, and liquid guide 141 fills the entire second liquid storage chamber 1111. This ensures that aerosol-generating substrate flowing out of the buffer space flows as far as possible onto liquid guide 141 without leakage. In other words, second liquid storage chamber 1111 substantially fills the entire width of housing 110 and conforms to the inner wall of housing 110.

[0071] In one embodiment, the first liquid storage chamber 130 is integrally formed with the housing 110. This means that the first liquid storage chamber 130 is non-replaceable, and the first liquid storage chamber 130 and the housing 110 can be molded in one piece using a glue injection process, reducing production costs. In this embodiment, the atomizer device functions as a disposable electronic atomizer product.

[0072] In one embodiment, please refer to Figure 2 The nozzle 120 is integrally provided with the housing 110. In addition, the atomizer 100 further includes an atomizing airway 170, which is integrally provided with the nozzle 120 and the housing 110 and is in communication with the heating element 142 for guiding the atomized aerosol to the nozzle 120.

[0073] Please refer to Figure 2 The atomizer 100 further includes an air-sealing element 171, which is disposed upstream of the atomizing air passage 170 and is used to seal the atomizing air passage 170. The provision of the air-sealing element 171 can, on the one hand, prevent air from passing through the atomizing air passage 170, thereby preventing the atomizing device from being accidentally activated. On the other hand, the air-sealing element 171 can maintain the internal air pressure of the second liquid storage chamber 1111 constant, thereby preventing liquid from leaking through the atomizing assembly 140 during bumpy transportation or temperature fluctuations.

[0074] Another embodiment of the present application provides an atomization device, comprising the aforementioned atomizer 100, and further comprising a power supply, an air pressure detection element, and a controller. The power supply, air pressure detection element, and controller are all disposed within the mounting cavity 111. The power supply is electrically connected to the heater 142, and the air pressure detection element outputs a first voltage signal in response to a user's puffing action. The controller is electrically connected to the power supply and the air pressure detection element, respectively, and is configured to receive the first voltage signal and, based on the first voltage signal, control the power supply to provide an operating voltage to the heater 142.

[0075] In this embodiment, the power supply and the heating element 142 are detachably connected.

[0076] The above examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. Those skilled in the art of the present invention can make some simple deductions, modifications or substitutions based on the concept of the present invention.
