Detailed Implementation

[0024] The technical solution of this application will be further described in detail below with reference to specific embodiments and accompanying drawings. In the following embodiments, many details are described to facilitate a better understanding of this application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by their components, materials, or methods. In some cases, certain operations related to this application are not shown or described in the specification. This is to avoid obscuring the core parts of this application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0025] Please see Figure 2 and Figure 3 In some embodiments of this application, an atomizing device is provided, which includes a liquid storage chamber 30, a receiving chamber 40, a liquid guiding member 2, an ultrasonic transducer 3, and an elastic connector 4. The liquid storage chamber 30 has a receiving space for storing a liquid atomizing matrix (not shown). At least a portion of the liquid guiding member 2 is located in the liquid storage chamber 30 for adsorbing the stored atomizing matrix.

[0026] The container 40 is in liquid communication with the liquid storage container 30 to provide atomization space. The container 40 is provided with a first limiting part 17.

[0027] The ultrasonic transducer 3 is disposed in the receiving chamber 40 and can vibrate along a first direction, which is perpendicular to the axial direction of the atomizing device. The ultrasonic transducer 3 has a first surface 31 that is relatively disposed and parallel to the axial direction of the atomizing device (e.g., ...). Figure 3 (as shown) and second surface 32 (as shown) Figure 3 (as shown in the image).

[0028] The elastic connector 4 is disposed between the first limiting part 17 of the accommodating chamber 40 and the first surface 31 of the ultrasonic transducer 3. The elastic connector 4 is configured to elastically drive the second surface 32 of the ultrasonic transducer 3 to abut against the liquid guide 2.

[0029] The ultrasonic transducer 3 is configured to ultrasonically atomize the atomizing matrix adsorbed on the liquid guide 2 to generate an aerosol in the containment chamber 40. The generated aerosol is eventually discharged into the external space for the user to inhale.

[0030] To facilitate understanding of the technical solution of this application, the axial direction of the atomizing device is defined as the Z-axis, which is consistent with the direction of gravity; the first direction is defined as the X-axis, which is consistent with the width direction of the atomizing device; and the thickness direction of the atomizing device is defined as the Y-axis.

[0031] The atomizing device provided in this application arranges the first surface 31 and the second surface 32 of the ultrasonic transducer 3 parallel to the axial direction of the atomizing device, i.e., the Z-axis. The second surface 32 of the ultrasonic transducer 3 is elastically driven by the elastic connector 4 to abut against the liquid guide 2 on which the atomizing matrix is ​​adsorbed, thus achieving liquid path communication between the ultrasonic transducer 3 and the liquid storage tank 30, thereby ultrasonically atomizing the atomizing matrix. The axial direction of the atomizing device is consistent with the direction of gravity, resulting in the ultrasonic transducer 3 being arranged vertically. Furthermore, the atomizing matrix adsorbed on the liquid guide 2 is atomized using a single-sided contact method, avoiding the risk of liquid atomizing matrix flowing back and covering the ultrasonic transducer 3 under gravity during use, which would reduce atomization efficiency. This significantly improves the efficiency and atomization effect of ultrasonic atomization.

[0032] In addition, the elastic connector 4 can adapt to the spatial displacement caused by the vibration of the ultrasonic transducer 3 during operation, so that the ultrasonic transducer 3 can maintain an elastic contact with the liquid guide 2 in the first direction, i.e., the X-axis, which improves the reliability of the liquid circuit connection between the ultrasonic transducer and the liquid storage tank 30, ensures continuous liquid supply, and further improves the efficiency and atomization effect of ultrasonic atomization.

[0033] The liquid guiding component 2 can be a multi-layer structure made of porous liquid-absorbing material, or it can be an integral structure made of porous liquid-absorbing material. The porous liquid-absorbing material can be natural or non-natural, such as natural degreased cotton, organic cotton, artificially synthesized plastic fibers, glass fibers, composite fibers, non-woven fabrics, porous ceramic materials, etc. The liquid guiding component 2 can be a columnar structure, tubular structure, sheet structure, block structure, irregular structure, etc. This application does not limit this and can select accordingly based on the actual use of the atomizing device.

[0034] In some embodiments, the liquid guiding component 2 is an integral columnar structure made of porous liquid-absorbing material, arranged parallel to the axial direction of the atomizing device, i.e., the Z-axis, so that the second surface 32 of the ultrasonic transducer 3 can abut against the side wall of the liquid guiding component 2 along the X-axis, i.e. the radial direction of the liquid guiding component 2. The liquid guiding component 2 itself has a certain strength and elasticity, ensuring that the liquid guiding component 2 can always maintain abutment against the second surface 32 of the ultrasonic transducer 3 during long-term use, further improving the reliability of the liquid channel connection between the liquid storage tank 30 and the ultrasonic transducer 3.

[0035] Please see Figure 1 and Figure 2 In some embodiments, the atomizing device of this application further includes a housing 1 and an air inlet 111 (e.g., Figure 2 (as shown) and air outlet 122, pipe section 5 (as shown) Figure 2 As shown in the figure, the liquid storage tank 30 and the container 40 are disposed in the shell 1.

[0036] The air inlet 111 and the air outlet 122 are respectively located at both ends of the housing 1. The air inlet 111 and the air outlet 122 are respectively connected to the outside. The accommodating chamber 40 can be located between the air outlet 122 and the liquid storage chamber 30. The air outlet 122 connects the accommodating chamber 40 with the outside space so that the generated aerosol can be discharged.

[0037] The pipe section 5 is located inside the housing 1, and the pipe section 5 connects the air inlet 111 and the accommodating chamber 40.

[0038] In actual use, the user draws air out of the mouth port 122, which creates negative pressure inside the atomizing device. Outside air enters the atomizing device through the air inlet 111 and enters the container chamber 40 under the guidance of the tube 5. Then, it carries the aerosol generated in the container chamber 40 out of the air outlet 122 for the user to inhale.

[0039] The main function of tube 5 is to guide the airflow entering the atomizing device through the air inlet 111 into the containment chamber 40, and then carry out the generated aerosol through the airflow. The inner diameter of tube 5 needs to ensure that a sufficient amount of airflow passes through per unit time, reducing the suction resistance of the atomizing device while ensuring the aerosol concentration of each inhalation. The inner diameter of tube 5 can be set according to the actual usage requirements of the atomizing device, and this application does not limit it.

[0040] Please see Figure 2 In some embodiments, at least a portion of the tube 5 is located in the liquid storage chamber 30, eliminating the need for additional storage space for the tube 5 within the housing 1. This allows the liquid storage chamber 30 to have a relatively larger capacity, ensuring the amount of liquid stored in the atomizing matrix while making full use of the limited space inside the atomizing device and improving the structural compactness of the atomizing device.

[0041] Please see Figure 2 In some embodiments, the tube 5 is a straight tube that extends parallel to the axial direction of the atomizing device, that is, the inner wall of the tube 5 is a smooth arc surface with uniformity everywhere, so that a sufficient amount of airflow can flow through the inner cavity of the tube 5 without obstruction.

[0042] In related technologies, some atomizing devices employ a dual-mode atomization method to atomize the same or different atomizing substrates. Specifically, the atomizing module of the device includes both an ultrasonic transducer 3 and a heated atomizing core. The heated atomizing core is typically located within the inner cavity of the tube 5, which is situated within the liquid storage chamber 30. A liquid passage hole is provided on the tube 5 to allow the atomizing substrate to pass through, thus establishing a liquid path connection between the heated atomizing core and the liquid storage chamber 30. During use, the airflow entering the tube 5 through the air inlet 111 carries away the heated aerosol after passing through the heated atomizing core. Due to the presence of the heated atomizing core, the airflow encounters additional resistance as it flows through the inner cavity of the tube 5. This increases suction resistance and reduces airflow velocity and flow rate, causing atomized particles in the aerosol to easily and rapidly condense into large droplets before being expelled. This not only affects the aerosol output or diffusion effect and reduces the aerosol content per puff, but also significantly impacts the aerosol's inhalation quality and taste, resulting in a poor user experience.

[0043] This atomizing device employs a single-mode atomization method to ultrasonically atomize the atomizing matrix. No additional obstructions, such as heating the atomizing core, are placed inside the tube 5, ensuring that the inner wall of the tube 5 has a uniformly smooth curved surface. This avoids the adverse effects of additional obstructions on airflow velocity and flow rate, reducing suction resistance during use. Simultaneously, it allows airflow to pass through the tube 5 at a relatively higher flow rate and velocity, significantly improving the aerosol output or diffusion effect generated by ultrasonic atomization. This ensures the aerosol content of each puff while preventing the rapid agglomeration of atomized particles into large droplets due to insufficient airflow velocity or flow rate, significantly improving aerosol quality and puffing taste, and enhancing the user experience.

[0044] In addition, the pipe section 5 is designed as a straight pipe, which avoids the additional resistance to airflow caused by the bending of the pipe section 5, and ensures the flow rate and velocity of the airflow passing through the pipe section 5.

[0045] Please see Figure 2 In some embodiments, the atomizing device of this application further includes an air inlet pipe 6 and an airflow sensor 7. The air inlet pipe 6 is disposed in the housing 1 and is used to connect the air inlet 111 and the pipe section 5 to guide the airflow entering through the air inlet 111 to the pipe section 5.

[0046] The airflow sensor 7 is installed inside the housing 1. The airflow sensor 7 is connected to the air intake pipe 6 to form an air passage and is configured to respond to suction negative pressure to control the operation of the ultrasonic transducer 3.

[0047] The atomizing device also includes a control module (not shown) and a power supply module (not shown). The control module is electrically connected to the ultrasonic transducer 3, the airflow sensor 7, and the power supply module. The control module receives the sensing signal emitted by the ultrasonic transducer 3 and controls the start and stop of the ultrasonic transducer 3 according to the sensing signal. The power supply module provides power to the ultrasonic transducer 3, the control module, and the airflow sensor 7.

[0048] During use, when the user inhales through the air outlet 122, creating a negative pressure inside the atomizing device, external airflow enters the air inlet pipe 6 through the air inlet 111. When the airflow sensor 7 detects that there is sufficient airflow passing through the air inlet pipe 6, it sends a sensing signal indicating that airflow is passing through to the control module of the atomizing device. The control module controls the ultrasonic transducer 3 to start operating based on the sensing signal. The ultrasonic transducer 3, based on the piezoelectric effect or magnetostrictive effect, converts the electrical signal sent by the control module into its own high-frequency mechanical vibration, thereby ultrasonically atomizing the atomizing matrix adsorbed on the liquid guide 2. The generated aerosol is discharged through the air outlet 122 under the influence of the airflow for the user to inhale.

[0049] When the user stops inhaling from the air outlet 122, the internal and external air pressures of the atomizing device are balanced, and there is no airflow through the tube 5, or only a slight change in airflow. When the airflow sensor 7 detects that there is not enough airflow through the air inlet tube 6, it sends a sensing signal of no airflow to the control module of the atomizing device. The control module controls the ultrasonic transducer 3 to stop operating based on the sensing signal to prevent the ultrasonic transducer 3 from continuing to operate when not in use.

[0050] The atomizing device of this application senses the airflow changes in the air intake pipe 6 through the airflow sensor 7, enabling the atomizing device to automatically start and stop the ultrasonic transducer 3 according to the airflow changes in the air intake pipe 6. Compared with the method of manually controlling the start and stop of the ultrasonic transducer 3, the atomizing device is greatly improved in terms of ease of use, and the power consumption is reduced, thus improving the battery life of the atomizing device.

[0051] Please see Figure 2 In some embodiments, the atomizing device of this application further includes an air intake regulating mechanism 8, which is connected between the air inlet 111 and the air intake pipe 6, and is configured to regulate the air intake volume of the air intake pipe 6.

[0052] In actual use, users can adjust the amount of air entering the air intake pipe 6 through the air intake adjustment mechanism 8, thereby controlling the flow rate and flow rate of the airflow in the pipe section 5, and realizing the control of the aerosol concentration and aerosol discharge under different working conditions of the atomizing device.

[0053] For example, in mouth-to-mouth inhalation, the ultrasonic transducer 3 can be set to operate at a relatively lower power. At this time, the nebulizer requires less airflow. The user can reduce the airflow entering the air intake pipe 6 through the air intake regulating mechanism 8, thereby reducing the concentration of aerosol inhaled per breath or increasing the amount of aerosol exhaled. In lung-to-lung inhalation, the ultrasonic transducer 3 can be set to operate at a relatively higher power. At this time, the nebulizer requires more airflow. The user can increase the airflow entering the air intake pipe 6 through the air intake regulating mechanism 8, thereby increasing the concentration of aerosol inhaled per breath or increasing the amount of aerosol exhaled.

[0054] The air intake regulating mechanism 8 can adopt a conventional design in the field. This application does not limit its specific structure, as long as it can realize the adjustment of the air intake volume of the air intake pipeline 6 and meet the air flow requirements of the atomizing device under different operating conditions.

[0055] Please see Figure 2 and Figure 4In some embodiments, the atomizing device of this application further includes a liquid suction element 9, which is disposed in the receiving chamber 40 and is used to absorb droplets in the flowing airflow. The liquid suction element 9 is provided with an airflow channel 91 for aerosol to pass through, and the airflow channel 91 is connected to the air outlet 122 so that the aerosol flows through the liquid suction element 9 before being discharged.

[0056] The liquid absorption element 9 is provided with a porous liquid absorption material for adsorbing liquid. The porous liquid absorption material can be any of the aforementioned porous liquid absorption materials. The air inlet end of the airflow channel 91 is connected to the air outlet end of the pipe section 5, so that the airflow entering through the air inlet 111 flows sequentially through the pipe section 5, the airflow channel 91, and the container 40, and then the airflow carries out the aerosol generated in the container 40 and discharges it through the air outlet 122.

[0057] The liquid absorption component 9 can absorb large droplets in aerosols using its own liquid absorption properties, preventing large droplets from being inhaled by the user and affecting the suction taste, thus improving the user experience.

[0058] The liquid-absorbing component 9 can be an integral structure made of porous liquid-absorbing material, or it can be an integral frame (not shown) with an airflow channel 91 constructed from a rigid non-liquid-absorbing material (such as plastic), and a porous liquid-absorbing material connected to the airflow channel 91 is provided in the integral frame. This application does not limit this, as long as it can meet the liquid-absorbing requirements.

Figure 5 As shown, the outer casing assembly includes an outer casing 11 and an upper end cap 12.

The upper end cap 12 is detachably connected to the upper end of the inner casing assembly. An air inlet 111 can be located at the bottom of the outer casing 11.

[0066] The atomizing device of this application uses the second limiting part 16 to stop the liquid guiding member 2 and the ultrasonic transducer 3, so that the second surface 32 of the ultrasonic transducer 3 can stably abut against the liquid guiding member 2, ensuring the reliability of the liquid path connection between the ultrasonic transducer 3 and the liquid storage tank 30. A receiving space is formed between the second limiting part 16 and the first limiting part 17 to accommodate the ultrasonic transducer 3 to vibrate in the first direction, which can accommodate the spatial displacement caused by the vibration of the ultrasonic transducer 3 during operation.

[0067] Please see Figure 4 and Figure 5 In some embodiments, the end face of the liquid storage tank 30, i.e., the bottom surface of the upper groove 131, is provided with a first through hole 134 communicating with the receiving tank 40 (e.g., Figure 5 As shown in the diagram, the first through-hole 134 is configured to allow the liquid guide 2 to pass through.

[0070] The first receiving groove 1621 can be arranged along the Z-axis, and the lower end of the first receiving groove 1621 penetrates the bottom surface of the end cap 162 to allow the liquid guiding component 2 to extend into it. The first receiving groove 1621 can, on the one hand, form a radial stop on the part of the liquid guiding component 2 that extends out of the first through hole 134, ensuring that the liquid guiding component 2 can stably abut against the second surface 32 of the ultrasonic transducer 3; on the other hand, the first receiving groove 1621 forms a partial wrapping of the part of the liquid guiding component 2 that extends out of the first through hole 134, which significantly reduces the volatilization or evaporation loss of the atomized matrix adsorbed on the liquid guiding component 2.

[0071] When the atomizing matrix in the storage tank 30 is insufficient, the user can manually remove the upper end cover 12 to expose the second limiting part 16 in the upper groove 131, and then manually remove the end cover 162 and pull out the liquid guide 2 to expose the first through hole 134. Subsequently, the atomizing matrix can be added to the storage tank 30 through the first through hole 134 to extend the service life of the atomizing device and reduce the cost of use.

[0072] Please see Figure 4 and Figure 5 In some embodiments, the first limiting part 17 includes a first seat 171, and a first stop surface 1711 is provided at one end of the first seat 171 facing the second limiting part 16. The first stop surface 1711 is arranged parallel to the ultrasonic transducer 3. A second receiving groove 19 is defined between the first stop surface 1711 and the second stop surface 1611 by a connecting structure 18 (e.g., Figure 5 As shown in the figure). The first stop surface 1711 is provided with a first notch 1712 (as shown in the figure). Figure 5 As shown in the diagram, the first notch 1712 connects to the second receiving groove 19. The ultrasonic transducer 3 is movably disposed in the second receiving groove 19.

[0073] The elastic connector 4 is housed in the first base 171, and one end of the elastic connector 4 elastically abuts against the inner wall of the first base 171 away from the first stop surface 1711, and the other end of the elastic connector 4 elastically abuts against the first surface 31 of the ultrasonic transducer 3 through the first notch 1712.

[0074] The second stop surface 1611, the connecting structure 18, and the first stop surface 1711 define a second receiving groove 19. The ultrasonic transducer 3 is movably disposed in this second receiving groove 19. That is, the second receiving groove 19 constitutes a receiving space for the ultrasonic transducer 3 to vibrate in the first direction, which can accommodate the spatial displacement caused by vibration during the operation of the ultrasonic transducer 3. The first notch 1712 is provided so that the other end of the elastic connector 4 can elastically abut against the first surface 31 of the ultrasonic transducer 3. On the other hand, it also allows the aerosol generated by atomization to diffuse into the receiving chamber 40 in a timely manner through the first notch 1712, ensuring the continuous generation of aerosol.

[0075] Please see Figure 5 In some embodiments, the first seat 171 has a third stop surface 1713 at the end away from the first stop surface 1711. The elastic connector 4 can be a compression spring, with one end of the compression spring elastically abutting against the third stop surface 1713 and the other end of the compression spring elastically abutting against the first surface 31 of the ultrasonic transducer 3 via the first notch 1712. The third stop surface 1713 has a third notch 1714, which is arranged opposite to the first notch 1712.

[0076] The air outlet end of the tube 5 passes through the bottom surface of the upper groove 131 and forms a second through hole 135. The second through hole 135 is located at the end of the first limiting part 17 away from the second limiting part 16.

[0077] The liquid suction member 9 is disposed at the end of the first limiting part 17 away from the second limiting part 16. The air inlet end of the airflow channel 91 is at least partially connected to the second through hole 135 and at least partially connected to the third notch 1714. The air outlet end of the airflow channel 91 is connected to the air outlet 122 so that the generated aerosol can be quickly carried out when the airflow passes through the airflow channel 91.

[0078] Please see Figure 2 In some embodiments, the bottom surface of the liquid storage tank 30 is provided with a liquid collection tank 151, and the atomizing matrix flows to the liquid collection tank 151 under the action of gravity, and the liquid guiding component 2 is at least partially located in the liquid collection tank 151.

[0079] The liquid collection tank 151 can be formed recessed from the surface of the first sealing body 15. The opening size of the liquid collection tank 151 can be set to be larger than the bottom size of the liquid collection tank 151, so that the liquid collection tank 151 forms a funnel-like structure, which facilitates the automatic collection of the atomized matrix in the liquid storage tank 30 to the liquid collection tank 151. When the atomized matrix in the liquid storage tank 30 is at a low liquid level, the liquid guide 2 can still adsorb the atomized matrix, ensuring the continuous liquid supply of the ultrasonic transducer 3 and the continuous generation of aerosol.

[0080] Please see Figure 2 In some embodiments, a support member 136 is also fixedly provided in the first receiving cavity of the first inner shell 13. The support member 136 can be a tubular structure arranged along the Z-axis. The upper end of the support member 136 is connected to the first through hole 134, and the liquid guide member 2 extends through the support member 136 into the liquid collection tank 151. The support member 136 can support the liquid guide member 2 in the axial direction, and play a role in limiting the liquid guide member 2 in the liquid storage tank 30, preventing the liquid guide member 2 from shifting or moving due to the vibration of the ultrasonic transducer 3.
