[0034] This application discloses an electronic atomizer, comprising a mouthpiece, a liquid reservoir, an atomizing component, a battery holder, a power generation component, a battery, and a housing. The liquid reservoir is located below the mouthpiece. The atomizing component is located within the liquid reservoir, with its top end connected to the mouthpiece. The battery holder is located below the liquid reservoir, its periphery sealed to the periphery of the liquid reservoir. An air chamber is formed between the top surface of the battery holder and the bottom surface of the liquid reservoir, connecting to the bottom end of the atomizing component. A vent hole is provided on the top surface of the battery holder, connecting to the air chamber. The power generation component is located on the top surface of the battery holder and within the air chamber, and is used to generate electricity by rotating under the drive of airflow. The battery is located within the battery holder and is electrically connected to the atomizing component and the power generation component. The housing is located outside the battery holder, and has an air inlet connecting to the outside atmosphere, which is connected to the vent hole.

[0035] In this electronic atomizer, when a user inhales through the mouthpiece, outside air flows into the mouthpiece through the air inlet, vent, air chamber, and atomizing component. The power generation component is located within the air chamber. The airflow causes the power generation component to rotate and generate electricity. The power generation component is electrically connected to the battery, thus storing the generated electricity in the battery. Therefore, this electronic atomizer can generate its own electricity during inhalation to alleviate battery drain.

[0036] Please combine Figures 1 to 5 The following will mainly describe the specific structure of the electronic atomizer 100.

[0037] The electronic atomizer 100 of this application includes a mouthpiece 110 and a housing 180. The housing 180 is inserted into the bottom end of the mouthpiece 110, and the inner cavity of the housing 180 communicates with the mouthpiece 110. The housing 180 and the mouthpiece 110 can be connected by interference fit, snap-fit, adhesive bonding, or screw connection. The housing 180 has an air inlet 181 that communicates with the outside atmosphere and its inner cavity. The number of air inlets 181 can be at least one. Preferably, the number of air inlets 181 can be at least two.

[0038] The electronic atomizer 100 of this application includes a liquid reservoir 120 for storing atomizing matrix. The liquid reservoir 120 is located within a housing 180, specifically below a mouthpiece 110. The top of the liquid reservoir 120 communicates with the mouthpiece 110, and the outer wall of the liquid reservoir 120 is connected to the inner wall of the housing 180. The liquid reservoir 120 includes an upper sealing seat 121, a middle shell 122, and a lower sealing seat 123, which are sequentially and sealingly fitted from top to bottom. The upper sealing seat 121 and the lower sealing seat 123 can respectively press-fit the top and bottom ends of the middle shell 122. Both the upper sealing seat 121 and the lower sealing seat 123 can be made of elastic materials (e.g., silicone, plastic, and / or rubber). The top of the upper sealing seat 121 extends into and seals the mouthpiece 110. The middle shell 122 can be made of rigid materials such as plastic, glass, or metal. By using the soft and hard connections between the upper sealing seat 121 and the middle shell 122, and between the lower sealing seat 123 and the middle shell 122, it is possible to ensure the sealing performance of the liquid storage chamber 120 while ensuring that it has sufficient rigidity to store the atomized matrix.

[0039] The electronic atomizer 100 of this application includes an atomizing component 130, which is disposed within a liquid storage chamber 120, that is, below a mouthpiece 110. The atomizing component 130 atomizes the atomizing matrix within the liquid storage chamber. The top of the atomizing component 130 is connected to the mouthpiece 110, thereby allowing the aerosol generated by the atomizing component 130 to be drawn in. The bottom of the atomizing component 130 is sealed and inserted into a lower sealing seat 123 (which may be an interference fit). The atomizing component 130 includes an atomizing tube 131, a liquid-guiding cotton 132, and an atomizing core 133, which are sequentially sleeved from the outside to the inside. The atomizing component 130 also includes a lead 134 and a fixing cylinder 135, which is sleeved within the atomizing tube 131 and located below the liquid-guiding cotton 132 and the atomizing core 133. The tip of pin 134 is electrically connected to the atomizing core 133, and the middle of pin 134 is clamped between the atomizing tube 131 and the fixing cylinder 135. The outer wall of the fixing cylinder 135 is recessed inward to form a clamping groove 136, which extends axially along the fixing cylinder 135 and passes through both ends of the fixing cylinder 135. The middle of pin 134 is clamped within the clamping groove 136. The fixing cylinder 135 is made of an elastic material (e.g., silicone, plastic, and / or rubber). The clamping effect of the clamping groove 136 provides good fixation for pin 134. The number of pins 134 can be at least two (adapted to the number of atomizing cores 133). The number of clamping slots 136 can be multiple, and the multiple clamping slots 136 are evenly arranged along the circumference of the fixed cylinder 135. Thus, through the positioning that covers the entire circumferential range, the limitation of the installation angle of the fixed cylinder 135 by a single slot / non-uniform slot can be avoided, which can greatly simplify the installation process and save time.

[0040] The electronic atomizer 100 of this application includes a battery holder 140, which is disposed within and connected to a housing 180. The battery holder 140 is located below a liquid reservoir 120, and its periphery extends towards the liquid reservoir 120 in a cylindrical structure, with the periphery of the battery holder 140 sealingly connected to the periphery of the liquid reservoir 120. An air chamber 150 is formed between the top surface of the battery holder 140 and the bottom surface of the liquid reservoir 120, and the air chamber 150 connects to the bottom end of an atomizing assembly 130. A vent 141 communicating with the air chamber 150 is provided on the top surface of the battery holder 140. The vent 141 may be streamlined (with polished inner walls) to reduce airflow resistance. The vent 141 communicates with an air inlet 181 in the housing 180, thereby allowing the air chamber 150 to connect to the outside atmosphere. The wall of the vent 141 extends upward to form an air guide tube 142, which improves the air intake effect of the air chamber 150 through the air guide tube 142.

[0041] The electronic atomizer 100 of this application includes a power generation component 160, which is disposed on the top surface of the battery holder 140 and located in the air chamber 150. The power generation component 160 is used to generate electricity by rotating under the drive of airflow. The power generation assembly 160 includes a drive impeller 161, a transmission belt 162, and a power generation unit 163. The top surface of the battery holder 140 extends upward to form a mounting groove 143, which is opposite to the bottom end of the atomizing assembly 130. The drive impeller 161 is disposed in the mounting groove 143 (which may be glued, snap-fitted, or screwed, etc.). The power generation unit 163 is disposed on one side of the drive impeller 161 and is connected to other parts of the top surface of the battery holder 140. The transmission belt 162 is rotatably connected to the shaft of the drive impeller 161 and the shaft of the power generation unit 163, respectively. The transmission belt 162 is suspended above the battery holder 140. The mounting groove 143 has a clearance opening on the side facing the power generation unit 163 to avoid the transmission belt 162. The clearance opening can penetrate the mounting groove 143 vertically. When the user draws air through the nozzle 110, a negative pressure is formed in the air chamber 150, and the outside air flows into the outer casing 180 through the air inlet 181. When the airflow passes through the power generation component 160, the airflow causes the blades of the drive impeller 161 to rotate, and the shaft of the drive impeller 161 rotates accordingly. Through the transmission belt 162, the shaft of the power generation unit 163 also rotates. The power generation unit 163 converts the mechanical energy of the rotation into electrical energy, which is further stored in the battery 170 (described in detail below).

[0042] In some embodiments, the power generation component 160 employs a highly integrated miniaturized design. The drive impeller 161 is precision injection molded from a lightweight ABS+PC composite material and may include 4 to 8 blades. The center of the drive impeller 161 is connected to an air bearing via a stainless steel shaft, enabling it to start rotating at a low airflow velocity of 0.5 m / s, matching the airflow intensity during normal user suction. The power generation unit 163 includes a ring-shaped permanent magnet and copper coils. The ring-shaped permanent magnet is made of neodymium iron boron strong magnetic material and is sleeved on the shaft end of the power generation unit 163. The copper coils can be in three groups, each with 500 turns and a wire diameter of 0.08 mm. The copper coils are positioned on the battery holder 140 (which is made of insulating material) corresponding to the ring-shaped permanent magnet. When the drive belt 162 drives the shaft of the power generation unit 163 to rotate, the ring-shaped permanent magnet rotates synchronously, forming a rotating magnetic field. The power generation principle of the power generation component 160 is as follows: When the user draws air, a negative pressure is formed in the air chamber 150. Outside air flows in at high speed through the air inlet 181 and vent 141. When the airflow velocity reaches approximately 0.5 m / s, it drives the drive impeller 161 to begin rotating. As the airflow velocity increases to 1 m / s (at normal suction intensity), the speed of the drive impeller 161 can reach 3000 r / min. At this time, the annular permanent magnet fixed on the drive impeller 161 rotates synchronously, causing the surrounding magnetic field to change periodically. The magnetic flux at the location of the copper coil changes with the rotation of the permanent magnet, generating an induced electromotive force in the copper coil, which can output an AC voltage of 3.2–4.5V. The direction of the induced current alternates with the change in the magnetic field, forming an AC current of 50–100 mA.

[0043] In some embodiments, the vent 141 is located on the side of the drive impeller 161 opposite to the power generation unit 163. This design, with the vent 141 and power generation unit 163 positioned on opposite sides of the drive impeller 161, means that only a single functional component needs to be matched in the radial space on each side, reducing the overall radial space requirement. Consequently, the electronic atomizer 100 can be made relatively small. This arrangement also avoids spatial interference between the airflow channel and components such as the drive belt 162, allowing the airflow channel to be approximately straight, resulting in minimal airflow velocity loss and stable power to the drive impeller 161.

[0044] In some embodiments, the height of the top of the air guide tube 142 is less than the height of the top of the mounting groove 143. When the gas from the vent 141 is conveyed upward through the air guide tube 142, if the top of the air guide tube 142 is flush with or higher than the top of the mounting groove 143, some gas may diffuse along the gap at the top of the mounting groove 143 to other areas of the air chamber 150 due to the shortest path principle (especially under the negative pressure environment formed by user suction). The height difference design creates a physical obstruction at the top of the mounting groove 143. After the gas flows out from the top of the air guide tube 142, since there is no direct escape channel above, it can only converge along the inner wall of the mounting groove 143 towards the area of ​​the drive impeller 161 below, forcing the airflow path to focus towards the drive impeller 161, reducing ineffective diffusion loss, thereby significantly improving the convergence efficiency of the gas flowing into the mounting groove 143 from the vent 141, and providing a stronger and more stable airflow power for the drive impeller 161.

[0045] In an embodiment where the vent 141 is located on the side of the drive impeller 161 away from the power generation unit 163, the bottom end of the pin 134 further penetrates into the battery holder 140 and is electrically connected to the battery 170. The pin 134 is located outside the mounting slot 143, and the bottom end of the pin 134 is located on the side of the drive impeller 161 away from the power generation unit 163. This allows for efficient use of the space in the battery holder 140, resulting in a smaller volume for the electronic atomizer 100. The side of the drive impeller 161 away from the power generation unit 163 is designated as the airflow input area for the vent 141 and the air guide 142, and this side has a gap (used to buffer airflow vibration). The bottom end of the pin 134 is inserted into the battery holder 140 on this side, effectively utilizing this gap space without requiring additional deep holes or increased radial dimensions in the battery holder 140. Compared to placing the bottom end of the pin 134 on the side of the drive impeller 161 facing the power generation unit 163, this arrangement reduces the radial space requirement of the battery holder 140.

[0046] In the above embodiment, in order to avoid the mounting groove 143, the bottom end of the pin 134 adopts an L-shaped bending structure. Its horizontal section extends from the bottom end of the fixed cylinder 135 to the side of the drive impeller 161 away from the power generation unit 163, and the vertical section penetrates vertically into the reserved hole of the battery rack 140. The reserved hole is located on the side of the battery rack 140 near the air guide cylinder 142. After the bottom end of the pin 134 passes through the reserved hole, it is electrically connected to the electrode of the battery 170 (detailed below).

[0047] As described above, the electronic atomizer 100 of this application includes a battery 170, which is disposed in a battery holder 140. Part of the electrodes of the battery 170 are electrically connected to pins 134 of the atomizing assembly 130. The battery 170 supplies power to the atomizing core 133, causing the atomizing core 133 to heat up and atomize the atomizing substrate. Another part of the electrodes of the battery 170 is electrically connected to a power generation unit 163 of a power generation assembly 160. The power generation unit 163 generates electrical energy which is stored in the battery 170, thus replenishing the battery 170 with electrical energy. The battery 170 may be a lithium battery 170. The AC power generated by the power generation unit 163 is processed by the rectifier and filter module. The surface-mount bridge rectifier converts the AC power into DC power, and the 10μF ceramic filter capacitor filters out the high-frequency ripple in the current, making the output current ripple coefficient ≤5%. Subsequently, the low dropout linear regulator stabilizes the voltage at 4.2V, and together with the 100mA current limiter, ensures that the electrical energy is safely stored in the lithium battery 170, completing the final conversion from gas kinetic energy to chemical energy.
