Atomizer and electronic atomization device

Abstract

The present application relates to an atomizer and an electronic atomization device. The atomizer comprises a resonant piece, a liquid guide piece and a cover piece. The resonant piece is provided with a resonant cavity for transmitting microwaves. The liquid guide piece is made of a wave-transparent material and is provided with a liquid guide channel and a guide outlet which are in communication with each other. The cover piece has a set porosity and covers the guide outlet. The microwaves in the resonant cavity can penetrate into the liquid guide channel, so that the polar molecules in the atomization medium generate heat under the action of the microwaves. Finally, the atomization medium absorbs heat and atomizes. Since the microwaves can enter the main heating space of the liquid guide channel, the atomization medium in different regions of the main heating space can have equal opportunities to absorb microwaves, eliminating the temperature gradient of the atomization medium in the heating space, ensuring uniform heating of the atomization medium, and the cover piece can prevent the liquid atomization medium from leaking out of the liquid guide channel, thereby improving the overall anti-leakage capability of the atomizer for the atomization medium.

Description

Technical Field

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

[0002] Electro-atomizing devices typically consist of a porous substrate and a heating resistor. The porous substrate buffers the liquid, and the heating resistor is mounted on it. The heating resistor converts electrical energy into heat energy, which is conducted to the liquid through the porous substrate. The liquid absorbs the heat and atomizes to form an aerosol that can be drawn in. However, the portion of the porous substrate closer to the heating resistor absorbs more heat, forming a high-temperature region, while the portion closer to the heating resistor absorbs less heat, forming a low-temperature region. This results in a temperature gradient on the porous substrate, meaning the heat is unevenly distributed across the ceramic substrate. Ultimately, this prevents the porous substrate and the entire electro-atomizing device from achieving uniform heating of the atomizing medium. Summary of the Invention

[0003] One of the technical problems solved by this invention is how to achieve uniform heating of the atomizing core.

[0004] An atomizer, comprising:

[0005] The resonator has a resonant cavity for transmitting microwaves;

[0006] The liquid guiding component is made of a wave-transparent material and has interconnected liquid guiding channels and outlets, wherein the liquid guiding channels are used to transport the atomizing medium; and

[0007] A capping element having a set porosity and sealing the outlet.

[0008] In one embodiment, the resonator also has an air intake channel communicating with the resonant cavity, and the cover is located inside the resonant cavity and detachably connected to the resonator, and the cover covers the air intake channel.

[0009] In one embodiment, the resonator includes an outer conductor and an inner guide post that together form the resonant cavity and are coaxially arranged; the outer conductor has a mist outlet at its top, the cover is disposed at the top of the outer conductor corresponding to the mist outlet, and the inner guide post is disposed at the bottom of the outer conductor.

[0010] In one embodiment, the inner guide post is a hollow structure with an air intake channel that connects to the resonant cavity.

[0011] In one embodiment, the inner guide post includes a conductive post, the bottom end of which is connected to the outer conductor, and the top end of which is spaced apart from the capping member; or, the inner guide post includes a conductive post and a stop post connected axially, the conductive post being close to the bottom of the outer conductor and connected to the outer conductor, and the stop post being close to the top of the outer conductor and abutting against and connecting to the capping member.

[0012] In one embodiment, there is a gap between the end of the conductive post away from the bottom of the outer conductor and the cover along the axial direction of the resonator, the gap being 1 mm to 10 mm.

[0013] In one embodiment, the liquid guiding element surrounds the inner guide post and is coaxially arranged with the inner guide post.

[0014] In one embodiment, the liquid guiding element is a spiral tube, the lumen of the spiral tube forms the liquid guiding channel, and the outlet is located at the end of the spiral tube.

[0015] In one embodiment, the atomizer further includes a microwave source located outside the resonant cavity, the microwave source transmitting microwaves through the guide post, and the microwaves generated by the microwave source having a frequency of 915 MHz to 5.8 GHz.

[0016] In one embodiment, the atomizer further includes a housing, a liquid reservoir, and a liquid pump. The resonator is at least partially housed within the housing. The liquid reservoir and the liquid pump are housed within the housing and located outside the resonant cavity. The liquid pump inputs the atomizing medium in the liquid reservoir into the liquid guiding channel.

[0017] In one embodiment, at least one of the following schemes is also included:

[0018] The cover is made of porous ceramic, honeycomb ceramic or foam metal;

[0019] The fluid guiding component is made of polytetrafluoroethylene or polyetheretherketone.

[0020] An electronic atomizing device includes a power source and an atomizer as described above, wherein the atomizer is connected to the power source.

[0021] One technical effect of an embodiment of the present invention is that microwaves in the resonant cavity can penetrate the liquid guiding component and enter the liquid guiding channel, causing high-frequency friction between polar molecules in the atomizing medium under the action of microwaves, generating heat, which ultimately causes the atomizing medium to absorb heat and atomize. Since microwaves can enter the main heating space of the liquid guiding channel, the atomizing medium in different areas of the main heating space has an equal opportunity to absorb microwaves, eliminating the temperature gradient of the atomizing medium in the heating space, ensuring uniform heating of the atomizing medium, thereby improving the inhalation experience of the atomizing medium and the user experience of the atomizer. More importantly, the capping component has porosity and seals the outlet. The capping component has both air guiding and liquid blocking functions, allowing it to impede liquid passage. This enables the capping component to fully exert its sealing effect, preventing the liquid atomizing medium in the liquid guiding channel from leaking out through the capping component, thereby improving the overall leak-proof capability of the atomizer.

[0027] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.

[0028] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "inner," "outer," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0029] See Figure 1 , Figure 2 and Figure 3 An embodiment of the present invention provides an atomizer 20 comprising a housing 100, a resonator 200, a liquid guide 300, a cap 400, a microwave source 510, a liquid reservoir 520, and a liquid pump 530. The resonator 200 is at least partially housed within the housing 100, and the microwave source 510, the liquid reservoir 520, and the liquid pump 530 are all housed within the housing 100.

[0030] See Figure 3 , Figure 4 and Figure 5 In some embodiments, the resonator 200 has a resonant cavity 260 for transmitting microwaves. This resonant cavity 260 can be a coaxial resonant cavity, such as a quarter-wavelength coaxial resonant cavity. The resonator 200 includes an outer conductor and an inner guide post 240 arranged coaxially. The outer conductor includes a top plate 210, a bottom plate 220, a side cylinder 230, and a suction nozzle 250. The top plate 210, bottom plate 220, side cylinder 230, and inner guide post 240 together form the resonant cavity 260, and all four are made of metal. Since metal has a microwave shielding function, it can effectively prevent microwaves inside the resonant cavity 260 from radiating outside the resonator 200, avoiding microwave loss and preventing leaked microwaves from causing harm to the human body. The side cylinder 230 can be cylindrical or prismatic. The top plate 210 is connected to one end of the side cylinder 230, and the bottom plate 220 is connected to the other end of the side cylinder 230. The inner guide post 240 is located inside the side cylinder 230. The inner guide post 240 includes a conductive post 242, which is fixed to the base plate 220. The conductive post 242 extends axially along the side cylinder 230, protruding relative to the base plate 220. Therefore, one end of the conductive post 242 is a fixed end, and the other end is a free end. The conductive post 242 is coaxially arranged with the side cylinder 230. The length of the conductive post 242 can be less than the length of the side cylinder 230, so that the free end of the conductive post 242 is spaced apart from the top plate 210 along the axial direction of the side cylinder 230; that is, the free end of the conductive post 242 does not extend to the position of the top plate 210. The conductive post 242 can be integrally connected to the base plate 220 or separately connected. The cross-section of the conductive post 242 can be circular, elliptical, rectangular, or regular polygonal, etc. The conductive post 242 can be made of metal materials such as aluminum.

[0031] In some embodiments, the inner guide post 240 includes a conductive post 242 and an abutment post connected axially, the conductive post 242 being close to and connected to the top plate 210, and the abutment post being close to the top plate 210 and abutting against the cover member 400.

[0032] See Figure 3 , Figure 4 and Figure 5 The microwave source 510 can also be a solid-state microwave source 510. The microwave frequency generated by the microwave source 510 is 915MHz to 5.8GHz, for example, the microwave frequency can be 915MHz, 2450MHz, or 5.8GHz. The microwave generated by the microwave source 510 is transmitted to the resonant cavity 260 through the inner guide post 240. Given the above-mentioned structural arrangement of the resonant cavity 260, on the one hand, the inner guide post 240 can eliminate the constraint of microwave energy attenuation, so that the microwave energy can be transmitted to the space near the free end of the inner guide post 240. As a result, the resonant cavity 260 has the strongest microwave distribution in the range between the free end of the inner guide post 240 and the top plate 210. In other words, the microwave will be mainly concentrated in the space between the free end of the inner guide post 240 and the top plate 210. On the other hand, the inner guide post 240 allows the smaller diameter resonant cavity 260 to meet the microwave transmission requirements, ensuring that microwaves can be transmitted to the space between the free end of the inner guide post 240 and the top plate 210. This reduces the outer diameter of the side tube 230 and the atomizer 20, thereby achieving a miniaturized and lightweight design of the atomizer 20, making it easier to carry and store, and improving the user experience of the atomizer 20.

[0033] See Figure 3 , Figure 4 and Figure 5 The suction nozzle 250 is located outside the resonant cavity 260 and is fixed to the top plate 210. The suction nozzle 250 extends axially along the side cylinder 230, causing it to protrude relative to the top plate 210. Therefore, one end of the suction nozzle 250 is a fixed end, and the other end is a free end. A portion of the suction nozzle 250 can be housed within the housing 100, while the other portion is located outside the housing 100, with the free end of the suction nozzle 250 located outside the housing 100. The suction nozzle 250 can be coaxially arranged with the side cylinder 230, making the suction nozzle 250, side cylinder 230, and inner guide post 240 coaxial. A suction channel 270 is provided on the suction nozzle 250 and the top plate 210, connecting the outside world and the resonant cavity 260. The user can contact the suction nozzle 250 to perform suction.

[0034] See Figure 2 and Figure 3The intake channel 270 may include two sections, referred to as the first intake section 271 and the second intake section 272, respectively. The first intake section 271 and the second intake section 272 are coaxially arranged. The first intake section 271 is positioned close to the resonant cavity 260, allowing it to directly connect to the resonant cavity 260. The second intake section 272 is positioned away from the resonant cavity 260, with one end directly connected to the first intake section 271 and the other end directly connected to the outside. Both the first and second intake sections 271 and 272 may be cylindrical, with the diameter of the first intake section 271 being larger than that of the second intake section 272. Along the axial direction of the side cylinder 230 from the first intake section 271 to the second intake section 272, the diameter of the first intake section 271 gradually decreases, while the diameter of the second intake section 272 remains constant. By setting the first intake section 271, a larger collection space is provided, facilitating the rapid entry of airflow from the resonant cavity 260 into the intake channel 270 and preventing the airflow from remaining in the resonant cavity 260 for an extended period. Given that the free end of the inner guide post 240 and the top plate 210 are spaced apart along the axial direction of the side cylinder 230, and the microwaves are mainly concentrated near the free end of the inner guide post 240, this effectively prevents microwaves within the resonant cavity 260 from leaking out through the intake channel 270. This avoids energy loss due to microwave leakage, improving the energy utilization rate of the atomizer 20, and also prevents leaked microwaves from posing a radiation hazard to the human body, thus enhancing the safety of using the atomizer 20.

[0035] See Figure 3 , Figure 4 and Figure 5 In some embodiments, the resonator 200 has an air intake channel 241. For example, the air intake channel 241 can be disposed on the inner guide post 240, making the inner guide post 240 a hollow tubular structure. The air intake channel 241 extends axially along the side cylinder 230 and penetrates the inner guide post 240. One end of the air intake channel 241 can connect to the outside, and the other end of the air intake channel 241 has an opening on the end face of the inner guide post 240 near the top plate 210, so that the other end of the air intake channel 241 connects to the resonant cavity 260. When the user draws at the suction nozzle 250, the outside air enters the resonant cavity 260 through the air intake channel 241 in the inner guide post 240. Alternatively, the air intake channel 241 can be disposed on the side cylinder 230, extending radially along the side cylinder 230 and penetrating the side cylinder 230. One end of the air intake channel 241 can connect to the outside, and the other end of the air intake channel 241 connects to the resonant cavity 260. Along the axial direction of the side cylinder 230, the air intake channel 241 is further away from the bottom plate 220 relative to the free end of the inner guide post 240, and the air intake channel 241 is closer to the bottom plate 220 relative to the top plate 210; in layman's terms, the air intake channel 241 is roughly located in the space between the inner guide post 240 and the top plate 210.

[0036] In some embodiments, the liquid guiding component 300 may be arranged around the inner guide post 240. The liquid guiding component 300 may be made of a microwave-transparent material such as polytetrafluoroethylene or polyetheretherketone, allowing microwaves in the resonant cavity 260 to pass through the liquid guiding component 300 and enter the liquid guiding channel 310. The atomizing medium in the liquid guiding channel 310 then absorbs the microwaves. Under the action of the microwaves, the polar molecules in the atomizing medium undergo high-frequency friction, generating heat. This causes the atomizing medium to absorb heat and atomize, forming an aerosol that can be inhaled by the user. The liquid guiding component 300 has a liquid guiding channel 310 and an outlet 320, which are interconnected. The liquid guiding channel 310 can connect to the resonant cavity 260 through the outlet 320, and the aerosol generated by the atomization of the atomizing medium in the liquid guiding channel 310 can be discharged outside the liquid guiding channel 310 through the outlet 320. The liquid storage unit 520 is used to store liquid atomizing medium. The liquid pump 530 can provide pump suction to the atomizing medium, so that the atomizing medium in the liquid storage unit 520 enters the liquid guiding channel 310 of the liquid guiding unit 300. That is, the liquid storage unit 520 supplies the atomizing medium to the liquid guiding channel 310 through the liquid pump 530.

[0037] See Figure 3 , Figure 4 and Figure 5 The outlet 320 is located on the end of the liquid guiding component 300 near the top plate 210. The outlet 320 is closer to the top plate 210 than the free end of the inner guide post 240, so that the outlet 320 and the free end of the inner guide post 240 are spaced apart along the axial direction of the side cylinder 230. That is, along the axial direction of the side cylinder 230, the outlet 320 is located between the top plate 210 and the free end of the inner guide post 240. The axial distance H between the outlet 320 and the free end of the inner guide post 240 can be 1mm to 10mm, for example, the specific value of the distance H can be 1mm, 5mm or 10mm, etc. Since the microwaves are mainly concentrated in the space between the free end of the inner guide post 240 and the top plate 210, the atomizing medium located between the outlet 320 and the free end of the inner guide post 240 in the liquid guiding channel 310 generates the most heat. The atomizing medium will atomize into an aerosol in the space between the outlet 320 and the free end of the inner guide post 240 in the liquid guiding channel 310. In layman's terms, the space between the outlet 320 and the free end of the inner guide post 240 in the liquid guiding channel 310 can be considered as the main heating space, while the other spaces in the liquid guiding channel 310 can be considered as the preheating space. Given that the axial distance between the outlet 320 and the free end of the inner guide post 240 can be 1mm to 10mm, the length of this axial distance is the axial length of the heating space.

[0038] See Figure 3 , Figure 4 and Figure 5For example, the liquid guiding component 300 can be a spiral tube. Obviously, the shape of this spiral tube is similar to a cylindrical spring with a spiral structure, and the cavity of the spiral tube will form a liquid guiding channel 310. By setting the liquid guiding component 300 as a spiral tube, the liquid guiding channel 310 is also spiral-shaped. Therefore, within a limited axial distance, the total length of the heating space can be reasonably extended, thereby reasonably extending the total time for the atomizing medium to flow through the heating space, ensuring that the atomizing medium has enough time to fully absorb microwaves and reach the atomization temperature for atomization. Alternatively, the liquid guiding component 300 can also be a straight tube, which includes an inner sleeve and an outer sleeve. The inner sleeve is arranged around the inner sleeve, and the outer sleeve is arranged around the inner sleeve. That is, the outer sleeve and the inner sleeve are arranged radially spaced along the side tube. The space between the inner sleeve and the outer sleeve will form a liquid guiding channel 310. When both the inner sleeve and the outer sleeve are cylindrical, the cross-sectional profile of the liquid guiding channel 310 is annular.

[0039] In some embodiments, the capping member 400 may be made of porous ceramic, honeycomb ceramic, or foamed metal, resulting in a large number of micropores within the capping member 400, thus forming a certain porosity. Porosity is defined as the percentage of the volume of pores in an object to the total volume of the material in its natural state. The porosity of the capping member 400 can be 20% to 60%, for example, values ​​such as 20%, 57%, 59%, or 60%. The cross-sectional size of the micropores is 1 μm to 100 μm, for example, values ​​such as 1 μm, 15 μm, 60 μm, or 100 μm. When the micropores are circular, the cross-sectional size of the micropores can be understood as the diameter of the micropores.

[0040] See Figure 3 , Figure 4 and Figure 5In some embodiments, the cover 400 can be directly fixed to the top plate 210 of the resonator 200, and the cover 400 can be detachably connected to the top plate 210. After the cover 400 is assembled, it will be located between the top plate 210 and the liquid guide 300, so that the cover 400 covers the outlet 320, preventing the atomizing medium in the liquid guide channel 310 from leaking out of the liquid guide channel 310 through the outlet 320. The axial distance between the cover 400 and the free end of the inner guide post 240 is the same as the axial distance between the outlet 320 and the free end of the inner guide post 240, so the axial distance between the cover 400 and the free end of the inner guide post 240 can be 1mm to 10mm. At the same time, the cover 400 can also cover the suction channel 270. Specifically, the cover 400 can cover the end of the first suction section 271 near the resonator cavity 260. Given that the cap 400 has a certain porosity, gas can pass through it and flow from one side to the other along its thickness, ensuring good gas conduction. Conversely, the cap 400 also provides some resistance to the liquid atomizing matrix, preventing the atomizing medium from passing through and flowing from one side to the other along its thickness, thus ensuring good liquid-blocking performance.

[0041] In other embodiments, for example, the capping member 400 can also be directly fixed to the inner guide post 240. The capping member 400 can be fixed to the inner guide post 240 by a connector made of a non-conductive, non-absorbing, or weakly absorbing material. The material of the connector can be quartz glass or alumina ceramic, etc. Alternatively, the capping member 400 can be directly fixed to the liquid-absorbing member.

[0042] See Figure 1 , Figure 2 and Figure 3When the atomizer 20 is working, the user will inhale through the mouthpiece 250. The liquid pump 530 is activated, delivering the atomizing medium from the liquid reservoir 520 to the liquid guiding channel 310. Simultaneously, the microwave source 510 is also operational, transmitting microwaves generated by it through the inner guide post 240 to the resonant cavity 260. Given the wave-transmitting nature of the liquid guiding component 300, the microwaves in the resonant cavity 260 will pass through the component and enter the liquid guiding channel 310. The atomizing medium in the main heating space of the liquid guiding channel 310 generates relatively more heat, thus atomizing and forming an aerosol. This aerosol will overflow from the outlet 320 to outside the liquid guiding channel 310. Furthermore, under the negative pressure generated by the user's suction, outside air will enter the resonant cavity 260 through the air inlet channel 241. Given that the gas can pass through the micropores in the cover 400, the air in the resonant cavity 260 carries the aerosol overflowing from the outlet 320 through the cover 400 into the intake channel 270, ultimately allowing the user to absorb the aerosol generated by the atomizing medium from the intake channel 270.

[0043] Since the cap 400 can impede the passage of liquid and seals the outlet 320, it can fully exert its sealing function to prevent the liquid atomizing medium in the liquid guiding channel 310 from leaking out of the liquid guiding channel 310. For example, it prevents the atomizing medium in the liquid guiding channel 310 from leaking into the resonant cavity 260, avoiding the leakage of atomizing medium from affecting the resonant frequency of the resonant cavity 260, thereby affecting the transmission effect of microwaves in the resonant cavity 260 and ensuring that microwaves can be transmitted to the area where the heating space is located. It also prevents the atomizing medium in the liquid guiding channel 310 from leaking into the suction channel 270, preventing the user from inhaling the atomizing medium in the suction channel 270, eliminating the influence of the atomizing medium on the inhalation experience, and improving the user experience of the atomizer 20. Since the cap 400 also blocks the suction channel 270, it can further prevent the atomizing medium from leaking into the suction channel 270. Since the air intake channel 241 can be opened on the inner guide post 240 or at the position of the side cylinder 230 near the free end of the inner guide post 240 and the top plate 210, it can effectively prevent the atomized medium leaking into the resonant cavity 260 from further overflowing into the air intake channel 241, thereby avoiding leakage of the atomized medium from the air intake channel 241.

[0044] Since the cover 400 is detachably connected to the top plate 210, if the cover 400 is damaged, such as preventing gas from passing through or failing to properly seal the outlet 320, the damaged cover 400 can be removed from the top plate 210 and a new cover 400 can be installed. This ensures that the cover 400 always has good gas-conducting and liquid-blocking functions.

[0045] The atomizing medium employs microwave absorption heating, causing high-frequency friction between polar molecules within the medium under the influence of microwaves, generating heat. In simpler terms, the atomizing medium has a self-heating function. Because microwaves can penetrate all parts of the liquid guiding channel 310, the atomizing medium in different areas within the heating space of the channel 310 has an equal opportunity to absorb microwaves, eliminating temperature gradients within the heating space and ensuring uniform heating. This improves the inhalation experience and enhances the user experience of the atomizer 20.

[0046] See Figure 1 , Figure 2 and Figure 3 The present invention also provides an electronic atomizing device 10, which includes an atomizer 20 and a power supply 30. The atomizer 20 is mounted on the power supply 30, for example, the atomizer 20 can be detachably connected to the power supply 30. The power supply 30 includes a battery 31 and a controller 32. The battery 31 is electrically connected to the controller 32 and a microwave source 510. When the controller 32 controls the battery 31 to supply power to the microwave source 510, the microwave source 510 generates microwaves, causing the atomizing medium in the liquid guiding channel 310 to absorb the microwaves and atomize. When the controller 32 controls the battery 31 to stop supplying power to the microwave source 510, the microwave source 510 will stop generating microwaves, so that the atomizing medium in the liquid guiding channel 310 cannot absorb microwaves and atomize. Of course, the controller 32 can also control the power supply of the battery 31 to the liquid pump 530. Obviously, when the battery 31 supplies power to the liquid pump 530, the liquid pump 530 can pump the atomized medium in the liquid storage device 520 into the liquid guiding channel 310. When the battery 31 stops supplying power to the liquid pump 530, the liquid pump 530 will stop pumping liquid. Since the atomized medium is difficult to leak through the air intake channel 241, it is prevented that the atomized medium leaking from the air intake channel 241 will further flow into the power supply 30, preventing the atomized medium from corroding the battery 31 in the power supply 30 and improving the service life of the power supply 30.
