This leads to problems such as leakage and dry burning in this type of atomizing core structure. Utility Model Content

Detailed Implementation

[0033] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present 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.

[0034] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.

[0035] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0036] In related technologies, the atomizing core structure typically uses a vertically placed liquid guide to wrap around the heating element (e.g., a metal mesh heating element), then they are fixed together in an mounting tube. Finally, the entire structure is installed into the liquid storage structure of the atomizing device. The liquid storage structure stores the atomizing matrix, and the liquid guide can transfer the atomizing matrix to the heating element, which can heat and atomize the atomizing matrix to produce an aerosol. This type of atomizing core structure has the following drawbacks:

[0037] First, due to the softness and flexibility of the heating element, the pressure conditions of different parts are different during assembly or use, which leads to unpredictable gaps between the heating element and the liquid guiding component. This may result in the heating element not fitting tightly with the liquid guiding component, causing problems such as dry burning and burnt core. This not only affects the user experience, but also makes it difficult to guarantee safety.

[0038] Secondly, the heating element is a mesh structure with a large porosity. After the product leaves the factory, it often requires several months or even a year of transportation and storage. With the changes in internal and external temperature and pressure, the internal air pressure squeezes the atomized matrix and causes it to leak directly from the mesh, affecting the normal use of the product.

[0039] To address the aforementioned problems, this application provides an atomizing core and an atomizing device. A vibrating element drives the atomizing element to vibrate at high frequency along the radial direction of the liquid guiding element, thereby atomizing the atomizing matrix present in the atomizing micropores into an aerosol. Compared to heating atomization methods, since heating is not required, problems such as dry burning and core clogging are avoided. Furthermore, the pore size of the atomizing micropores is on the micrometer scale, preventing the atomizing matrix from leaking into the atomizing element and thus eliminating leakage.

[0040] See Figure 1 and Figure 2 As shown, the atomizing core 10 provided in this embodiment is installed in the atomizing device and is in fluid communication with the liquid storage chamber 20 of the atomizing device. The liquid storage chamber 20 is used to store the atomizing matrix. The atomizing core 10 and the liquid storage chamber 20 constitute the atomizing device. The liquid storage chamber 20 can provide the stored atomizing matrix to the atomizing core 10. In this application, the atomizing core 10 can atomize the atomizing matrix into an aerosol by ultrasonic atomization to avoid the problems of dry burning and core scorching caused by heating.

[0041] The atomizing core 10 includes a liquid guiding component 12, an atomizing component 13, and a vibrating component 14. The liquid guiding component 12 is tubular in shape, and the atomizing core 10 can be installed inside the liquid storage chamber 20.

[0042] At least a portion of the liquid guiding element 12 is disposed inside the liquid storage chamber 20 and is in fluid communication with the liquid storage chamber 20. The atomizing matrix within the liquid storage chamber 20 can be transferred to the liquid guiding element 12, specifically absorbed by the liquid guiding element 12. The liquid guiding element 12 is used to transfer the atomizing matrix to the atomizing element 13.

[0043] The atomizing matrix is ​​in liquid form. The liquid guiding component 12 is usually made of fiber cotton. The liquid guiding component 12 can absorb the atomizing matrix transferred from the liquid storage tank 20 by adsorption, thus buffering the atomizing matrix. Furthermore, the buffered atomizing matrix can permeate to the atomizing component 13, thereby transferring the atomizing matrix to the atomizing component 13.

[0044] The atomizing element 13 is disposed inside the liquid guiding element 12 and in contact with the liquid guiding element 12 to receive the atomizing matrix transferred by the liquid guiding element 12. See [link to relevant documentation]. Figures 2-7 As shown, the atomizing element 13 has a plurality of atomizing micropores 131 that extend through it and connect to its interior.

[0045] In this application, the liquid guiding member 12 is tubular in shape, and an installation channel 121 is formed inside it along its axial direction. The atomizing member 13 is installed in the installation channel 121 of the liquid guiding member 12 so as to be inside the liquid guiding member 12.

[0046] In some embodiments, the atomizing element 13 contacts the mounting channel 121 of the liquid guide element 12 in a close fit, so as to contact the channel wall of the mounting channel 121 in order to receive the atomized matrix transferred by the liquid guide element 12.

[0047] Of course, in other embodiments, when the liquid guide 12 is installed with the atomizing element 13, it can also be rolled up and wrapped around the outside of the atomizing element 13. This not only forms a tubular shape, but also allows the channel wall of the installation channel 121 to fit against the outer wall of the atomizing element 13, so that the atomizing element 13 contacts the liquid guide 12 and is installed inside the liquid guide 12.

[0048] The vibrating element 14 is attached to the inside of the atomizing element 13. The vibrating element 14 is used to drive the atomizing element 13 to generate reciprocating vibration along the radial direction of the liquid guiding element 12 when it is energized. Specifically, the vibrating element 14 can be energized and de-energized in a reciprocating manner to drive the atomizing element 13 to generate reciprocating vibration along the radial direction of the liquid guiding element 12.

[0049] After the liquid guiding component 12 transfers the atomizing matrix to the atomizing component 13, the atomizing matrix is ​​present in the atomizing micropores 131. In this embodiment, the axial direction of the atomizing micropores 131 is parallel to the radial direction of the liquid guiding component 12. The atomizing component 13 continuously squeezes the liquid guiding component 12 under the action of reciprocating vibration. When the atomizing component 13 reciprocates and squeezes the liquid guiding component 12, the atomizing component 13 can atomize the atomizing matrix in the atomizing micropores 131 to generate an aerosol.

[0050] In this embodiment, the vibrating element 14 can be made of piezoelectric ceramic material. Based on the piezoelectric effect, when an alternating voltage is applied to the two poles of the piezoelectric ceramic structure, the piezoelectric ceramic structure will generate mechanical vibration of the same frequency. When the frequency of the alternating voltage is within the audio range, high-frequency vibration can be generated under the action of reciprocating energization and de-energization, thereby generating ultrasonic waves. The high-frequency vibration generated by the vibrating element 14 can drive the atomizing element 13 to generate reciprocating vibration along the radial direction of the liquid guiding element 12.

[0051] The pore size of the atomizing micropores 131 is usually in the micrometer range. When the atomizing element 13 is driven by the vibrating element 14 to reciprocate along the radial direction of the liquid guiding element 12 and squeeze the liquid guiding element 12, the atomizing matrix can be dispersed into particulate atomizing matrix through the atomizing micropores 131. The particulate atomizing matrix can generate an aerosol when mixed with air.

[0052] Specifically, the liquid-form atomizing matrix existing in the atomizing micropores 131, due to the surface tension and pressure of the liquid-form atomizing matrix itself, will be dispersed into many tiny particulate atomizing matrices when the atomizing element 13 is driven by the vibrating element 14 to reciprocate along the radial direction of the liquid guiding element 12, thereby achieving the atomization effect. The reciprocating vibration of the atomizing element 13 along the radial direction of the liquid guiding element 12 generates kinetic energy, which enhances the interaction force between the liquid-form atomizing matrix molecules. The liquid-form atomizing matrix molecules then undergo high-frequency vibration, which increases the surface tension of the atomizing matrix, making it easier to form tiny particulate atomizing matrices.

[0053] See also Figure 1 and Figure 2 As shown, since the liquid guiding component 12 is made of fiber cotton and is relatively soft, in order to facilitate its installation, the atomizing core 10 provided in this embodiment also includes an installation tube 11. The installation tube 11 forms an installation and positioning structure for the liquid guiding component 12, the atomizing component 13 and the vibrating component 14. The installation tube 11 is fixedly installed inside the liquid storage chamber 20. The tube wall of the installation tube 11 is provided with at least one liquid guiding hole 111 through it. The atomizing matrix stored in the liquid storage chamber 20 can enter the interior of the installation tube 11 through the liquid guiding hole 111.

[0054] The liquid guiding component 12 is used to transfer the atomizing matrix to the atomizing component 13 through the liquid guiding hole 111. Specifically, the liquid guiding component 12 is installed inside the mounting tube 11. The liquid guiding component 12 can absorb and buffer the atomizing matrix that enters from the liquid storage tank 10 into the mounting tube 11 through the liquid guiding hole 111, and transfer the atomizing matrix to the atomizing component 13 through permeation.

[0055] In this embodiment, the atomizing device is further provided with a power supply unit, a first electrode 244, and a second electrode 245. The atomizing element 13 has a first pin 133, and the vibrating element 14 has a second pin 143. The first pin 133 of the atomizing element 13 is electrically connected to the first electrode 244, and the second pin 143 of the vibrating element 14 is electrically connected to the second electrode 245. The first electrode 244 and the second electrode 245 can be connected to the first and second electrodes of the power supply unit, respectively. The power supply unit, through the reciprocating alternating power-on and power-off action, enables the vibrating element 14 to generate high-frequency vibration along the radial direction of the liquid guide element 12. When the preset vibration frequency is reached, ultrasonic waves can be generated. The atomizing element 13 can reciprocate along the radial direction of the liquid guide element 12 synchronously with the vibrating element 14, so that the atomizing element 13 applies the reciprocating vibration to the liquid guide element 12, thereby continuously squeezing the liquid guide element 12 and acting on the atomizing micropores 131, so that the atomizing matrix present in the atomizing micropores 131 forms a particulate atomizing matrix to generate an aerosol.

[0056] In this application, the ultrasonic waves generated by the vibrating element 14 drive the atomizing element 13 to reciprocate at the same frequency along the radial direction of the liquid guiding element 12, continuously compressing the atomizing matrix transferred by the liquid guiding element 12. This causes the atomizing matrix to form granular atomizing matrix after passing through the atomizing micropores 131. The granular atomizing matrix generates an aerosol after mixing with air. Thus, aerosols are generated through the principle of ultrasonic vibration, and the atomizing element 13 itself does not generate heat, effectively avoiding the problems of dry burning and wick clogging. At the same time, since the atomizing micropores 131 are micron-sized, the atomizing matrix is ​​not easily able to pass through the atomizing micropores 131 under its own tension, thus preventing leakage.

[0057] See Figures 1-4 As shown, the atomizing device includes a housing 23 and a base assembly 24, as... Figure 3 As shown, one end of the outer shell 23 has an opening 230, and the base assembly 24 is sealed and installed at the opening 230 at one end of the outer shell 23, so that the base assembly 24 and the outer shell 23 together define the liquid storage chamber 20. The base assembly 24 has an installation port 241, and the outer shell 23 has an air guide tube 231 inside. The air guide tube 231 and the outer shell 23 can be an integral structure. The atomizing core 10 is disposed between the installation port 241 and the air guide tube 231. The base assembly 24 also has an air inlet channel 242 through the installation port 241. The air inlet channel 242 is connected to the outside of the atomizing device. The air guide tube 231 has an air outlet channel 232. The atomizing core 10 is connected to both the air inlet channel 242 and the air outlet channel 232.

[0058] In this embodiment, a sealing element 25 is also provided between the atomizing core 10 and the air outlet channel 232. One end of the mounting tube 11 of the atomizing core 10 is connected to one end of the air outlet channel 232 through the sealing element 25. The outer shell 23 is also provided with a mouthpiece 21, and the mouthpiece 21 is also provided with a mouthpiece channel 211 that is connected to the other end of the air outlet channel 232. The other end of the mounting tube 11 is sealed and connected to the mounting port 241. Thus, in actual use, the user can draw in air through the nozzle 21, allowing external gas to enter the interior of the mounting tube 11 through the air inlet channel 242 and the mounting port 241. After the atomizing element 13 is driven by the vibrating element 14 to generate reciprocating vibration in the radial direction of the liquid guiding element 12, the atomizing micropores 131 continuously squeeze the atomizing matrix transferred by the liquid guiding element 12 to generate particulate atomizing matrix. The particulate atomizing matrix mixes with the airflow entering the interior of the mounting tube 11 to generate an aerosol, which can be output through the air outlet channel 232 and the nozzle channel 211.

[0059] See Figures 1-4 As shown, the outer shell 23 is also provided with a liquid injection hole 213 on its shell wall. The liquid injection hole 213 is connected to the liquid storage chamber 201. The atomizing matrix can be added to the liquid storage chamber 201 through the liquid injection hole 213 so that the atomizing device can be recycled, thereby saving the user's operating costs.

[0060] A sealing element 22 is also provided on the outside of the outer casing 23. The sealing element 22 has a sealing part 221, which is used to seal the injection hole 213. In a specific embodiment, the sealing element 22 is made of materials such as silicone. After the sealing part 221 is installed into the injection hole 213, it can be press-fitted with the injection hole 213 to achieve the purpose of sealing the injection hole 213.

[0061] The sealing component 22 also has a connecting rod portion 222, and a mounting hole 214 is provided on the shell wall of the outer casing 23. The connecting rod portion 222 is installed through the mounting hole 214. When it is necessary to add atomizing matrix through the injection hole 213, it is only necessary to separate the sealing component 221 from the injection hole 213. Through the cooperation between the connecting rod portion 222 and the mounting hole 214, the sealing component 22 can be connected to the outer casing 23, preventing the sealing component 22 from being lost after disassembly.

[0062] See also Figures 1-4 As shown, the base assembly 24 includes a bottom cover 243, a first electrode 244, and a second electrode 245. The bottom cover 243 is installed at an opening 230 at one end of the outer casing 23. The first electrode 244 and the second electrode 245 are disposed through the bottom cover 243, and at least a portion of the first electrode 244 and the second electrode 245 are exposed outside the bottom cover 243. The first electrode 244 is electrically connected to the first pin 133 of the atomizing element 13, and the second pin 245 is electrically connected to the second pin 143 of the vibrating element 14.

[0063] In this application, the atomizing device can be detachably connected to the power supply unit. After the two are connected, the parts of the first electrode 244 and the second electrode 245 exposed on the bottom cover 243 can be electrically connected to the first electrode and the second electrode of the power supply unit, respectively, so as to supply power through the power supply unit.

[0064] See Figures 2-5 As shown, the atomizing element 13 has a hollow interior and is open at both ends in a tubular structure. An atomizing channel 130 is formed inside the atomizing element 13, and each atomizing micropore 131 is connected to the atomizing channel 130. The liquid guiding element 12 is wrapped around the outer periphery of the atomizing element 13, and the vibrating element 14 is disposed inside the atomizing element 13 and is in contact with or connected to the channel wall of the atomizing channel 130 inside the atomizing element 13. In this embodiment, the vibrating element 14 is in contact with the channel wall of the atomizing channel 130 inside the atomizing element 13 to ensure that vibration is transmitted to the atomizing element 13.

[0065] In this embodiment, a plurality of atomizing micropores 131 are arranged in an array at intervals around the central axis of the atomizing element 13 on the sidewall of the atomizing element 13.

[0066] See Figure 7As shown, the atomizing micropore 131 has an inlet 1311 and an outlet 1312. The inlet 1311 is located on the outer wall of the atomizing element 131, or the inlet 1311 is located close to the outer wall of the atomizing element 131. The outlet 1312 is located on the inner wall of the atomizing element 131, or the outlet 1312 is located close to the inner wall of the atomizing element 131.

[0067] In this embodiment, the area of ​​the inlet 1311 is smaller than the area of ​​the outlet 1312. This arrangement makes the area of ​​the inlet 1311 near the liquid guide 12 smaller than the area of ​​the outlet 1312 away from the liquid guide 12. Since the area of ​​the inlet 1311 is smaller than the area of ​​the outlet 1312, the atomizing matrix is ​​not easy to leak through the atomizing micropores 131 on the side of the inlet 1311 due to its own tension. Only when the atomizing element 13 vibrates at the same frequency as the vibrating element 14, the tension of the atomizing matrix is ​​broken, and the atomizing matrix can be sprayed out through the atomizing micropores 131 along the direction from the inlet 1311 to the outlet 1312 to form a particulate atomizing matrix.

[0068] See also Figure 7 As shown, along the radial direction of the atomizing component 13, the aperture of the atomizing micro-hole 131 gradually increases, which makes the area of ​​the inlet 1311 smaller than the area of ​​the outlet 1312, and at the same time makes the atomizing micro-hole 131 form a shape similar to a conical hole.

[0069] In this application, the particle size of the generated particulate atomizing matrix is ​​related to the size of the atomizing micropores 131. The pore size of the atomizing micropores 131 is between 5μm and 18μm, for example, it can be 5μm, 6μm, 7μm, 8μm, 9μm...18μm. The smaller the pore size of the atomizing micropores 131, the smaller the particle size of the generated atomizing matrix particles. The pore size of the atomizing micropores 131 can be selected according to actual needs.

[0070] See Figure 2 , Figure 3 as well as Figure 8 As shown, the vibrating element 14 includes a connecting portion 141 and at least two driving portions 142. The driving portions 142 have a ring-shaped structure. The at least two driving portions 142 are connected to the connecting portion 141 at intervals along the length direction of the connecting portion 141, and the at least two driving portions 142 are located on the same side of the connecting portion 141.

[0071] In this application, the vibrating member 14 is provided with two driving parts 142, and the connecting part 141 is approximately rod-shaped. The two driving parts 142 are respectively provided at both ends of the connecting part 141 in the length direction. The second pin 143 is electrically connected to the connecting part 141. Furthermore, the connecting part 141 can electrically connect the two driving parts 142, so that each driving part 142 can generate reciprocating vibration in the radial direction of the liquid guiding member 12.

[0072] After the vibrating element 14 is installed inside the atomizing tube 13, the radial direction of the annular driving part 142 is the same as the radial direction of the atomizing element 13. At least the driving part 142 is in contact with the channel wall of the atomizing channel 130 so that the driving part 142 contacts or connects to the atomizing channel 130 of the atomizing element 13. It can quickly transmit its own reciprocating vibration along the radial direction of the liquid guide 12 to the atomizing element 13 so as to ensure that the atomizing element 13 can generate reciprocating vibration along the radial direction of the liquid guide 12.

[0073] See Figure 3 , Figure 4 as well as Figure 8 As shown, the vibrating element 14 is tubular in shape. In this application, the outer diameter of the vibrating element 14 is adapted to the inner diameter of the atomizing channel 130 inside the atomizing element 13, so that the vibrating element 14 can be fitted and fixed to the channel wall of the atomizing channel 130 inside the atomizing element 13.

[0074] After the vibrating element 14 is installed inside the atomizing element 13, conforming to the channel wall of the atomizing channel 130, to prevent the connecting part 141 and the driving part 142 from blocking the atomizing micropores 131 and affecting the atomization effect, in this application, a clearance area 1421 is formed between two adjacent driving parts 142. This clearance area 1421 is used to avoid each atomizing micropore 131, so that the particulate atomizing matrix generated by the atomizing matrix passing through the atomizing micropores 131 can be sprayed into the interior of the atomizing channel 130, and then output through the nozzle channel 211 by the external gas entering the atomizing channel 130. Of course, the area where each atomizing micropore 131 is located on the atomizing element 13 corresponds to the position of the clearance area 1421.

[0075] See Figure 5 As shown, the atomizing element 13 has a first break 132 along its axial direction. The atomizing element 13 is usually made of stainless steel. The first break 132 allows the atomizing element 13 to release tension outward so as to fit tightly against the inside of the liquid guide 12. At the same time, it provides vibration space for the atomizing element 13 when it vibrates at the same frequency as the vibrating element 14.

[0076] In this embodiment, the connecting portion 141 of the vibrating member 14 is provided with a second break 1411 through its length. After the vibrating member 14 is installed in the atomizing channel 130 of the atomizing member 13, the second break 1411 and the first break 132 are positioned to correspond to each other. The setting of the second break 1411 allows the vibrating member 14 to release outward tension so as to stick tightly to the inner wall of the atomizing member 13.

[0077] In some embodiments, the length of the vibrating element 14 along its longitudinal direction is the same as the length of the atomizing element 13 along its axial direction. In this application, the vibrating element 14 has a cylindrical structure, and a second break 1411 is provided through the vibrating element 14 along its axial direction. The clearance area 1421 is a notch structure formed on the vibrating element 14. The outer diameter of the vibrating element 14 is adapted to the inner diameter of the atomizing channel 130 so that the vibrating element 14 can fit against the channel wall of the atomizing channel 130, thereby allowing the vibrating element 14 to contact the atomizing element 13.

[0078] See Figures 1-4 As shown, this application also provides an atomizing device, which includes a housing 23, a base assembly 25, and the atomizing core 10 in the above embodiments, as shown. Figure 3 As shown, one end of the outer shell 23 has an opening 230, and the base assembly 24 is sealed and installed at the opening 230 at one end of the outer shell 23, so that the base assembly 24 and the outer shell 23 together define the liquid storage chamber 20. The base assembly 24 has an installation port 241, and the outer shell 23 has an air guide tube 231 inside. The air guide tube 231 and the outer shell 23 can be an integral structure. The atomizing core 10 is disposed between the installation port 241 and the air guide tube 231. The base assembly 24 also has an air inlet channel 242 through the installation port 241. The air inlet channel 242 is connected to the outside of the atomizing device. The air guide tube 231 has an air outlet channel 232. The atomizing core 10 is connected to both the air inlet channel 242 and the air outlet channel 232.

[0079] In this embodiment, a sealing element 25 is also provided between the atomizing core 10 and the air outlet channel 232. One end of the mounting tube 11 of the atomizing core 10 is connected to one end of the air outlet channel 232 through the sealing element 25. The outer shell 23 is also provided with a mouthpiece 21, and the mouthpiece 21 is also provided with a mouthpiece channel 211 that is connected to the other end of the air outlet channel 232. The other end of the mounting tube 11 is sealed and connected to the mounting port 241. Thus, in actual use, the user can draw in air through the nozzle 21, allowing external gas to enter the interior of the mounting tube 11 through the air inlet channel 242 and the mounting port 241. After the atomizing element 13 is driven by the vibrating element 14 to generate reciprocating vibration in the radial direction of the liquid guiding element 12, the atomizing micropores 131 continuously squeeze the atomizing matrix transferred by the liquid guiding element 12 to generate particulate atomizing matrix. The particulate atomizing matrix mixes with the airflow entering the interior of the mounting tube 11 to generate an aerosol, which can be output through the air outlet channel 232 and the nozzle channel 211.

[0080] See also Figures 1-4As shown, the base assembly 24 includes a bottom cover 243, a first electrode 244, and a second electrode 245. The bottom cover 243 is installed at an opening 230 at one end of the outer casing 23. The first electrode 244 and the second electrode 245 are disposed through the bottom cover 243, and at least a portion of the first electrode 244 and the second electrode 245 are exposed outside the bottom cover 243. The atomizing element 13 has a first pin 133, and the vibrating element 14 has a second pin 143. The first electrode 244 is electrically connected to the first pin 133 of the atomizing element 13, and the second pin 245 is electrically connected to the second pin 143 of the vibrating element 14.

[0081] In this application, the atomizing device can be detachably connected to the power supply unit. After the two are connected, the parts of the first electrode 244 and the second electrode 245 exposed on the bottom cover 243 can be electrically connected to the first electrode and the second electrode of the power supply unit, respectively, so as to supply power through the power supply unit.

[0082] In summary, in the atomizing core and atomizing device provided in this application, the atomizing element can reciprocate at high frequency along the radial direction of the liquid guide element and continuously compress the liquid guide element, thereby compressing the atomizing matrix present in the atomizing micropores to form granular atomizing matrix. The granular atomizing matrix generates an aerosol after mixing with air. The atomizing element itself does not generate heat, thus effectively avoiding the problems of dry burning and scorching. At the same time, since the atomizing micropores are made at the micron level, the atomizing matrix is ​​not easily able to pass through the atomizing micropores under the action of its own surface tension, thus preventing the problem of liquid leakage.

[0083] The above examples illustrate this application only to aid understanding and are not intended to limit its scope. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the ideas presented.
