Description

Technical Field

[0001] The present invention relates to the technical field of atomization equipment, and in particular to an atomizer, an electronic atomization device, and an atomization method for an aerosol-generating matrix. Background Art

[0002] A nebulizer is a device that atomizes an aerosol-generating matrix into an aerosol. It is widely used in medical equipment and electronic atomization devices.

[0003] At present, nebulizers generally use porous ceramics in combination with a heating surface to atomize the aerosol-forming matrix and form an aerosol. However, when using porous ceramics for atomization, the various components of the aerosol-forming matrix are unevenly transported in the ceramics during the boiling process. In addition, the particle size of the aerosol formed by atomization is difficult to control. The nebulizers used in medical treatment to atomize the aerosol-forming matrix based on a negative pressure-driven jet method have a small amount of atomization and a large amount of noise when atomizing a high-viscosity aerosol-forming matrix. Summary of the Invention

[0004] The present application provides a nebulizer, an electronic atomization device, and an atomization method for an aerosol-generating substrate, which can solve the problem of low atomization volume when the existing nebulizer atomizes high-viscosity aerosols.

[0005] To solve the above technical problems, the first technical solution adopted in this application is to provide an atomizer. The atomizer includes a bubble flow cavity and a bubble flow injection head. The bubble flow cavity is used to mix an aerosol-generating substrate with a gas to form a bubble flow. The bubble flow injection head is connected to the bubble flow cavity and is used to inject the bubble flow to form an aerosol.

[0006] To solve the above technical problems, the second technical solution adopted by this application is to provide an electronic atomization device. The electronic atomization device includes an atomizer and a power supply assembly; wherein the atomizer is the atomizer mentioned above; and the power supply assembly is connected to the atomizer for supplying power to the atomizer.

[0007] To solve the above technical problems, the third technical solution adopted in this application is to provide a method for atomizing an aerosol-generating substrate. The method includes: mixing the aerosol-generating substrate with a gas through a bubble flow cavity to form a bubble flow; and ejecting the bubble flow through a bubble flow ejector to form an aerosol.

[0008] The present application provides an atomizer, an electronic atomization device, and an atomization method for an aerosol-generating matrix. The atomizer is provided with a bubble flow cavity to allow the aerosol-generating matrix to mix with the gas and form a bubble flow; at the same time, a bubble flow injection head is provided to connect the bubble flow injection head with the bubble flow cavity so that the bubble flow is injected through the bubble flow injection head to form an aerosol; wherein, since the aerosol-generating matrix is ​​first mixed with the gas and forms a bubble flow before being sprayed and atomized, the surface tension of the bubble flow is utilized to achieve atomization, thereby reducing the influence of the viscosity of the aerosol-generating matrix on the atomization process, not only can the atomization amount of the aerosol be effectively increased, but also the various components of the aerosol-generating matrix can be evenly sprayed out.

[0019] The present application is described in detail below with reference to the accompanying drawings and embodiments.

[0020] See also Figure 1 , Figure 1 This is a schematic diagram of the structure of an electronic atomization device provided in one embodiment of the present application. In this embodiment, an electronic atomization device 100 is provided. The electronic atomization device 100 can be used to atomize an aerosol-generating substrate to form an aerosol for inhalation by a user. Specifically, the electronic atomization device 100 can be an electronic cigarette or a portable medical atomizer, and the aerosol-generating substrate can be tobacco oil, a liquid medicine, or other liquid that can be atomized and inhaled.

[0021] Specifically, the electronic atomization device 100 includes an atomizer 10 and a main unit 20. The atomizer 10 and the main unit 20 are detachably connected. The atomizer 10 is used to heat and atomize the aerosol-generating matrix when powered on. The main unit 20 is provided with a power supply assembly. The atomizer 10 is plugged into a port on one end of the main unit 20 and connected to the power supply assembly in the main unit 20, so that the power supply assembly supplies power to the atomizer 10. When the atomizer 10 needs to be replaced, the atomizer 10 can be removed and a new atomizer 10 installed on the main unit 20, allowing the main unit 20 to be reused.

[0022] Of course, the electronic atomization device 100 also includes other components in the existing electronic atomization device, such as a microphone, a bracket, etc. The specific structures and functions of these components are the same as or similar to those in the prior art. Please refer to the prior art for details and will not be repeated here.

[0023] In one embodiment, see Figure 2 , Figure 2 This is a structural schematic diagram of an atomizer provided in one embodiment of the present application; the atomizer 10 may specifically include a bubble flow cavity 11, a bubble flow injection head 12, an air storage cavity 13, a liquid storage cavity 14 and a pressure container 15.

[0024] The bubble flow cavity 11 is used to mix the aerosol generating matrix with the gas to form a bubble flow. The viscosity of the aerosol generating matrix can be a high-viscosity aerosol generating matrix with a viscosity of not less than 200 cps at room temperature. In a specific embodiment, when the flowing aerosol generating matrix contacts the gas, the two form a plurality of bubbles 31, and the plurality of bubbles 31 converge with the flow of the aerosol generating matrix to form a bubble flow.

[0025] Specifically, the bubble flow cavity 11 may be a columnar structure having a receiving cavity, and the aerosol generating substrate and the gas are mixed in the receiving cavity to form the bubble flow.

[0026] The bubble flow injection head 12 may be specifically disposed at one end of the bubble flow cavity 11 and at the middle of the bubble flow cavity 11 and communicated with the bubble flow cavity 11 for injecting the bubble flow to form aerosol 41; for details, see Figure 3 , Figure 3 This is a schematic diagram of the principle of bubble atomization provided in one embodiment of the present application; the bubble flow injection head 12 is formed with a through hole, and when the bubble flow in the bubble flow cavity 11 passes through the through hole, it is stretched and deformed by the hole wall of the through hole, and breaks at an end of the through hole away from the bubble flow cavity 11, thereby forming an aerosol 41 with a smaller particle size; wherein, by forming bubbles 31 and utilizing the surface tension of the bubble flow to achieve atomization, it is possible to reduce the influence of the viscosity of the aerosol generating matrix on the atomization process, effectively increase the atomization amount of the aerosol 41, and enable the various components of the aerosol generating matrix to be evenly brought out, thereby ensuring the consistency of taste.

[0027] Specifically, the radial dimension of the through hole gradually decreases from the end close to the bubble flow cavity 11 toward the end away from the bubble flow cavity 11, so as to utilize the surface of the bubbles 31 to atomize the aerosol 41 into a matrix. Of course, the radial dimension of the through hole remains constant from the end close to the bubble flow cavity 11 toward the end away from the bubble flow cavity 11, that is, the through hole is a constant diameter hole.

[0028] Among them, the gas storage cavity 13 is connected to the bubble flow cavity 11 and is used to store gas; the liquid storage cavity 14 is used to store the aerosol generating matrix; the pressure vessel 15 is connected to the gas storage cavity 13 and the liquid storage cavity 14, and is used to drive the gas in the gas storage cavity 13 to flow to the bubble flow cavity 11, and drive the aerosol generating matrix in the liquid storage cavity 14 to flow to the bubble flow cavity 11, so that the aerosol generating matrix entering the bubble flow cavity 11 contacts the gas entering the bubble flow cavity 11 and forms a plurality of bubbles 31.

[0029] In a specific embodiment, the gas storage cavity 13 is arranged on the outside of the bubble flow cavity 11, and has a first common wall with the bubble flow cavity 11, and a plurality of first connecting holes are opened on the first common wall to connect the gas storage cavity 13 and the bubble flow cavity 11, so that the gas in the gas storage cavity 13 can enter the bubble flow cavity 11 through the first connecting holes; it can be understood that the bubble 31 is formed at the port of the first connecting hole at one end facing the accommodating cavity.

[0030] Specifically, in the examples, see Figure 2 The gas storage cavity 13 is arranged along the periphery of the bubble flow cavity 11 and surrounds the periphery of the bubble flow cavity 11. The first common wall can be an annular side wall; the gas storage cavity 13 forms an annular cavity to store gas.

[0031] In another specific embodiment, see Figure 4 , Figure 4 This is a schematic diagram of the structure of an atomizer according to another embodiment of the present application. The bubble flow cavity 11 is disposed outside the gas storage cavity 13 and shares a first common wall with the gas storage cavity 13. A plurality of first communication holes are formed in the first common wall to connect the gas storage cavity 13 and the bubble flow cavity 11. Specifically, the plurality of first communication holes are evenly distributed along the first common wall to ensure that the bubbles 31 formed are evenly distributed within the bubble flow cavity 11.

[0032] Specifically, in this embodiment, the gas storage cavity 13 has a cylindrical cavity to store gas; the bubble flow cavity 11 includes a first cavity portion and a second cavity portion, the first cavity portion is arranged along the periphery of the gas storage cavity 13, and is arranged around the gas storage cavity 13, and has a first common sub-wall with the gas storage cavity 13; the second cavity portion is arranged between the gas storage cavity 13 and the bubble flow injection head 12, and has a second common sub-wall with the gas storage cavity 13; wherein, the first common sub-wall and the second common sub-wall form a first common wall.

[0033] Specifically, the first cavity portion and the second cavity portion are integrally formed and communicated; see Figure 4 The vertical cross section of the bubble flow cavity 11 is approximately in the shape of a "door".

[0034] In one embodiment, the liquid storage chamber 14 and the pressure container 15 are arranged at one end of the bubble flow chamber 11 away from the bubble flow injection head 12, so as to facilitate the user to hold it with his hands; in one embodiment, see Figure 2 , the liquid storage cavity 14 and the pressure container 15 are arranged side by side along the radial direction of the bubble flow cavity 11; in another specific embodiment, see Figure 4 The liquid storage cavity 14 is arranged around the periphery of the pressure container 15 . Of course, in other embodiments, the pressure container 15 can also be arranged around the periphery of the liquid storage cavity 14 .

[0035] For details, see Figure 2 and Figure 4 The atomizer 10 further includes a first control element 16 , a second control element 17 , a third control element 18 and a fourth control element 19 .

[0036] In a specific embodiment, the liquid storage cavity 14 and the bubble flow cavity 11 have a second common wall, the gas storage cavity 13 and the pressure vessel 15 have a third common wall, the liquid storage cavity 14 and the pressure vessel 15 have a fourth common wall; the bubble flow injection head 12 and the bubble flow cavity 11 have a fifth common wall.

[0037] Among them, the first control element 16 can be specifically set on the second common wall to control the communication between the bubble flow cavity 11 and the liquid storage cavity 14; specifically, when the atomizer 10 needs to be used, the first control element 16 is controlled to open to connect the bubble flow cavity 11 and the liquid storage cavity 14.

[0038] The second control element 17 can be specifically arranged on the third common wall, and is used to control the communication between the pressure container 15 and the gas storage cavity 13; specifically, when the atomizer 10 needs to be used, the second control element 17 is controlled to open to connect the pressure container 15 and the gas storage cavity 13, so that the gas in the gas storage cavity 13 is driven by the pressure container 15 to flow to the bubble flow cavity 11 through the first connecting hole.

[0039] The third control element 18 is specifically provided on the fourth common wall and is used to control the communication between the pressure container 15 and the liquid storage cavity 14. Specifically, when the atomizer 10 is needed and the first control element 16 and the second control element 17 are turned on, the third control element 18 is controlled to be turned on to connect the pressure container 15 and the liquid storage cavity 14, thereby driving the aerosol generating substrate in the liquid storage cavity 14 to flow toward the bubble flow cavity 11 through the pressure container 15. It can be understood that when the first control element 16 is turned on, it is difficult for the aerosol generating substrate in the liquid storage cavity 14 to spontaneously flow toward the bubble flow cavity 11. 1, the pressure vessel 15 needs to be driven to smoothly enter the bubble flow cavity 11. This can prevent the aerosol-generating substrate from entering the bubble flow cavity 11 and entering the gas storage cavity 13 through the first connecting hole when the atomizer 10 is idle. When the third control element 18 is opened, since the pressure vessel 15 is connected to the gas storage cavity 13 and the liquid storage cavity 14 at the same time, the pressure balance in the gas storage cavity 13 and the bubble flow cavity 11 can be controlled by the pressure vessel 15, thereby preventing the aerosol-generating substrate that has entered the bubble flow cavity 11 from entering the gas storage cavity 13 through the first connecting hole.

[0040] The fourth control element 19 is specifically disposed on the fifth common wall and is used to control the connection between the bubble flow injection head 12 and the bubble flow cavity 11. Specifically, when the user needs to inhale the aerosol 41, the fourth control element 19 is controlled to open, thereby connecting the bubble flow injection head 12 with the bubble flow cavity 11, allowing the bubble flow to be sprayed and atomized through the bubble flow injection head 12.

[0041] In one embodiment, see Figure 5 , Figure 5 This is a structural diagram of a nebulizer provided in yet another embodiment of the present application; the nebulizer 10 may further include a detector 23 and a controller 24.

[0042] The detector 23 may be disposed at a port on the end of the bubble flow injection head 12 away from the bubble flow cavity 11, and is used to detect and send an activation signal to the atomizer 10. Specifically, the detector 23 may be a sensor, and the activation signal may be a negative pressure signal at the port on the end of the bubble flow injection head 12 away from the bubble flow cavity 11. For example, when a user inhales, a negative pressure is formed at a corresponding position of the bubble flow injection head 12, and the sensor senses the negative pressure and generates a negative pressure signal. The controller 24 is connected to the detector 23 and is used to receive the activation signal and control the fourth control element 19 to activate according to the activation signal, thereby connecting the bubble flow injection head 12 to the bubble flow cavity 11.

[0043] Specifically, the first control element 16 , the second control element 17 , the third control element 18 and / or the fourth control element 19 are control valves.

[0044] Specifically, the pressure vessel 15 can be integrally formed with the bubble flow cavity 11, the gas storage cavity 13, and the liquid storage cavity 14, or it can be a separate pressure gas tank that stores gas with a certain pressure; since the pressure gas tank does not require a pressure pump, it can effectively reduce product noise. In one embodiment, the atomizer 10 has an integrally formed shell that forms the bubble flow cavity 11, the gas storage cavity 13, the liquid storage cavity 14, and the pressure vessel 15. In another embodiment, the atomizer 10 has an integrally formed outer shell and a plurality of partitions arranged in the outer shell to divide the space within the outer shell into the bubble flow cavity 11, the gas storage cavity 13, the liquid storage cavity 14, and the pressure vessel 15.

[0045] In one specific embodiment, to reduce the particle size of the aerosol 41 formed by the injection, the atomizer 10 may include a heating element 22. The heating element 22 is disposed at least at one end of the bubble flow injection head 12 away from the bubble flow cavity 11. The heating element 22 heats and further atomizes the aerosol 41 ejected from the bubble flow injection head 12, thereby further reducing the particle size of the aerosol 41 and controlling the particle size of the aerosol 41 within a certain range. Specifically, the heating temperature of the heating element 22 may be 60°C to 90°C.

[0046] In a specific embodiment, the atomizer 10 further includes a nozzle assembly 21. The nozzle assembly 21 may be disposed at an end of the bubble flow injection head 12 that is distal from the bubble flow cavity 11 and communicates with the bubble flow injection head 12 for aspirating the aerosol 41 ejected from the bubble flow injection head 12. Specifically, the nozzle assembly 21 may include an air guide tube, one end of which is sheathed around the bubble flow injection head 12. In this embodiment, the heating element 22 is specifically disposed between the bubble flow injection head 11 and the nozzle assembly 21.

[0047] Specifically, one end of the heating element 22 can abut against the outer wall of the bubble flow cavity 11 on the side facing the bubble flow injection head 12, and be arranged around the bubble flow injection head 12. In a specific embodiment, the heating element 22 can be an annular structure, which is specifically arranged around the air duct to continuously heat the aerosol 41 ejected from the bubble flow injection head 12 as it passes through the air duct. In one embodiment, one end of the shell of the atomizer 10 has a groove, the bubble flow injection head 12 is arranged at the bottom of the groove, one end of the air duct of the nozzle assembly 21 is arranged in the groove and abuts against the bottom wall of the groove and is sleeved around the bubble flow injection head 12, and the heating element 22 is arranged around the air duct of the nozzle assembly 21 and abuts against the side wall and bottom wall of the groove.

[0048] The working principle of the atomizer 10 is described in detail below.

[0049] When the controller 24 detects the user's start signal, it controls the first control element 16 and the second control element 17 to open, so that the pressure container 15 is connected to the gas storage cavity 13, and the liquid storage cavity 14 is connected to the bubble flow cavity 11, so that the pressure container 15 is used to drive the gas in the gas storage cavity 13 into the bubble flow cavity 11; then the third control element 18 is controlled to open, so that the pressure container 15 is connected to the liquid storage cavity 14, and the pressure container 15 is used to drive the aerosol generating matrix in the liquid storage cavity 14 into the bubble flow cavity 11, so that the aerosol generating matrix and the gas form bubbles 31 at the interface of the first connecting hole, and the bubbles 31 form a bubble flow with the flow of the aerosol generating matrix.

[0050] Afterwards, when the controller 24 detects the start signal (for example, the suction signal) of the atomizer 10 through the detector 23, the controller 24 controls the fourth control element 19 to start, and the bubble flow moves toward the bubble flow injection head 12 under the action of the pressure difference, and is stretched and deformed by the hole wall of the bubble flow injection head 12, and is broken at the outlet of the bubble flow injection head 12 to form an aerosol 41; at the same time, the heating element 22 starts to work and further heats and atomizes the formed aerosol 41 to obtain an aerosol 41 with a smaller particle size; when the detector 23 no longer detects the start signal, the fourth control element 19 is controlled to close, thereby completing the suction process of the aerosol 41.

[0051] The atomizer 10 provided in this embodiment adopts a two-phase flow atomization method in which gas and an aerosol-generating matrix are mixed in the atomizer 10, so that the aerosol-generating matrix is ​​first mixed with the gas to form a bubble flow before being sprayed and atomized, so as to utilize the surface tension of the bubble flow to achieve atomization. In this way, while reducing the influence of the viscosity of the aerosol-generating matrix on the atomization process, it can not only effectively increase the atomization amount of the aerosol 41, but also enable the various components of the aerosol-generating matrix to be sprayed uniformly; at the same time, by configuring the pressure container 15 as a pressure gas tank, the atomizer 10 does not need to use a pressure pump, thereby effectively reducing product noise; in addition, by providing a heating element 22 to heat the formed aerosol 41, the particle size of the final aerosol 41 can be effectively reduced, so that the particle size of the aerosol 41 can be controlled within a certain range.

[0052] See also Figure 6 , Figure 6 This is a flow chart of a method for atomizing an aerosol-generating substrate provided in one embodiment of the present application. In this embodiment, a method for atomizing an aerosol-generating substrate is provided, and the method specifically includes:

[0053] Step S11: mixing the aerosol-generating substrate with the gas to form a bubble flow.

[0054] Specifically, the aerosol generating matrix and the gas are mixed through the bubble flow cavity 11 to form a bubble flow; in the specific implementation process, the aerosol generating matrix and the gas are obtained respectively, the aerosol generating matrix and the gas contact at the interface and form a plurality of bubbles 31, and the plurality of bubbles 31 form a bubble flow along with the flow of the aerosol generating matrix; for details, please refer to the relevant text description of the atomizer 10 in the above embodiment, which will not be repeated here.

[0055] Step S12: ejecting bubble flow and forming aerosol.

[0056] Specifically, the bubble flow is ejected through the bubble flow ejection head 12 to form the aerosol 41. In a specific implementation, after the bubble flow ejection head 12 is connected to the bubble flow cavity 11, the bubble flow ejection head 12 ejects the bubble flow to form the aerosol 41. The specific process can be found in the relevant text description of the atomizer 10 in the above embodiment, and will not be repeated here.

[0057] In one embodiment, see Figure 7 , Figure 7 Flowchart of the aerosol generation substrate atomization method provided in another embodiment of the present application; In order to reduce the particle size of the aerosol 41 and ensure the consistency of the taste, relative to Figure 6 The method further comprises:

[0058] Step S13: heating the aerosol.

[0059] Specifically, the aerosol 41 formed by the spraying is heated by the heating element 22 to atomize the aerosol 41 to form aerosol 41 with a smaller particle size; specifically, the heating temperature can be 60°C-90°C.

[0060] The present embodiment provides a method for atomizing an aerosol-generating matrix. This method mixes the aerosol-generating matrix with a gas to form a bubble flow, thereby utilizing the surface tension of the bubble flow to achieve atomization. This method can effectively increase the atomization amount of the aerosol 41 while reducing the influence of the viscosity of the aerosol-generating matrix on the atomization process, and can also enable the various components of the aerosol-generating matrix to be sprayed out uniformly. At the same time, by heating the formed aerosol 41, the particle size of the aerosol 41 obtained by suction is effectively reduced, so that the particle size of the aerosol 41 can be controlled within a certain range.

[0061] The above is only an implementation method of the present application and does not limit the patent scope of the present application.
