The atomizer comprises: a piston wall with a through-hole; a magnetostrictive element located on one side of the piston wall along the axial direction of the through-hole; a piston rod with one end fixed to the magnetostrictive element and the other end extending axially into the through-hole; and a microporous screen disposed on the surface of the piston wall away from the magnetostrictive element and covering the opening end of the through-hole.

Description

Technical Field

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

[0002] Compared with traditional respiratory disease treatments, nebulization therapy, which uses a nebulizer to disperse drugs into tiny droplets or particles (i.e., aerosols), suspends them in gas and enters the respiratory tract and lungs to humidify the airways and treat respiratory inflammation, has advantages such as higher local drug concentration, shorter time to effect, and fewer systemic side effects because it allows aerosols to be deposited directly on the affected area.

[0003] Currently, common nebulizers on the market include compressed air nebulizers, ultrasonic nebulizers, and mesh nebulizers. Among them, compressed air nebulizers are noisy during use, and the aerosol particles are relatively large, limiting the amount of aerosol that effectively reaches the affected area. Ultrasonic nebulizers and mesh nebulizers usually use piezoelectric ceramics as driving elements, which pose a lead hazard and affect the user's health. Moreover, the amplitude generated by piezoelectric ceramics is limited, making it difficult to atomize high-viscosity medications. Summary of the Invention

[0004] Therefore, it is necessary to provide an atomizing device to address the problems of atomizers' difficulty in atomizing high-viscosity liquids and their low safety performance.

[0005] According to one aspect of this application, an atomizer is provided, comprising:

[0006] A through hole is made through the piston wall;

[0007] A magnetostrictive element is located on one side of the piston wall in the axial direction of the connecting hole;

[0008] The piston rod has one end fixed to the magnetostrictive element and the other end extending axially into the communicating hole; and

[0009] A microporous screen is disposed on the side of the piston wall away from the magnetostrictive member and covers the opening end of the communicating hole;

[0010] The magnetostrictive component can deform along the axial direction of the connecting hole under the action of a magnetic field, thereby driving the piston rod to reciprocate along the axial direction of the connecting hole to move closer to or away from the microporous screen.

[0011] In one embodiment, the atomizer further includes a coil wound around the magnetostrictive member, the coil being capable of generating an alternating magnetic field under the action of electrical energy.

[0012] In one embodiment, when the piston rod moves to its limit position in the direction close to the microporous screen, the end face of the piston rod facing the microporous screen is flush with the side surface of the piston wall where the microporous screen is located.

[0013] In one embodiment, a liquid inlet groove is provided on the side surface of the piston wall where the microporous screen is located. One end of the liquid inlet groove is connected to the connecting hole, and the other end of the liquid inlet groove extends away from the connecting hole.

[0014] According to another aspect of this application, an atomizing device is provided, including the atomizer described above. The atomizing device further includes an electronic control component and a liquid storage tank. The atomizer is installed on the electronic control component, and the liquid storage tank is located on one side of the electronic control component. The liquid storage tank has an outlet for communicating with the atomizer.

[0015] In one embodiment, a liquid inlet groove is provided on the side surface of the piston wall where the microporous screen is located. One end of the liquid inlet groove is connected to the connecting hole, and the other end of the liquid inlet groove extends away from the connecting hole.

[0016] The atomizer can be controlled to rotate around the central axis of the connecting hole so that the liquid inlet is aligned with or misaligned with the liquid outlet.

[0017] In one embodiment, a return groove is provided on the side surface of the piston wall where the microporous screen is located. One end of the return groove is connected to the connecting hole, and the other end of the return groove is used to connect to the liquid storage tank.

[0018] In one embodiment, the piston rod reciprocates horizontally, and the liquid reservoir is located above the atomizer.

[0019] In one embodiment, the piston rod reciprocates vertically, and the liquid reservoir is located on one side of the atomizer in the radial direction of the connecting hole.

[0020] In one embodiment, the atomizing device further includes an atomizing nozzle disposed on the side of the microporous screen away from the piston wall.

[0021] In one embodiment, the atomizing nozzle is located on one side of the liquid storage tank in the horizontal direction, and the atomizing nozzle includes an inlet end communicating with the microporous screen and an outlet end located above the inlet end;

[0022] In the direction of gravity, the edge of the outlet end extends downward at an angle from the side closest to the liquid storage tank toward the side furthest from the liquid storage tank.

[0023] Compared to existing technologies that use piezoelectric ceramics to atomize the aerosol-generating matrix, the atomizer described in this application utilizes a magnetostrictive element to atomize the aerosol-generating matrix. This results in better thermal stability, higher electromechanical conversion efficiency, and a larger coefficient of expansion, thus effectively atomizing high-viscosity liquids and expanding the application range of the atomizer. Furthermore, since the magnetostrictive element achieves atomization by driving the piston rod to reciprocate without contacting the aerosol-generating matrix, the risk of heavy metal ion release is reduced, resulting in higher safety.

[0039] See Figure 1 An embodiment of this application provides an atomizing device 100 for heating an aerosol generating matrix to generate an aerosol for user use. The aerosol generating matrix is ​​in liquid form and includes, but is not limited to, materials used for medical, health, or cosmetic purposes, such as liquid medicines or oils.

[0040] The atomizing device 100 includes an electronic control component 40, an atomizer 20, and a liquid storage tank 60. The atomizer 20 is mounted on the electronic control component 40, and the liquid storage tank 60 is located on one side of the electronic control component 40. The liquid storage tank 60 is used to store liquid aerosol generating matrix and has an outlet for connecting to the atomizer 20. The aerosol generating matrix in the liquid storage tank 60 flows into the atomizer 20 through the outlet. Under the control of the electronic control component 40, the atomizer 20 atomizes the aerosol generating matrix to generate aerosol for the user.

[0041] The atomizer 20 includes a piston wall 21, a magnetostrictive element 23, a piston rod 27, and a microporous screen 29. The magnetostrictive element 23 can drive the piston rod 27 to reciprocate relative to the piston wall 21 under the action of a magnetic field, thereby pushing the aerosol generating matrix to the microporous screen 29. The aerosol generating matrix passes through the microporous screen 29 and is refined into an aerosol for the user to use.

[0042] Compared to existing technologies that use piezoelectric ceramics to atomize the aerosol-generating matrix, the atomizer 20 of this application utilizes a magnetostrictive element 23 to atomize the aerosol-generating matrix, resulting in better thermal stability, higher electromechanical conversion efficiency, and a larger coefficient of expansion. Therefore, it can effectively atomize high-viscosity liquids, expanding the application range of the atomizer 20. Furthermore, since the magnetostrictive element 23 achieves atomization by driving the piston rod 27 to reciprocate, without directly contacting the aerosol-generating matrix, the risk of heavy metal ion precipitation is reduced, resulting in higher safety.

[0043] Please combine Figures 2 to 4As shown, the piston wall 21 has a cylindrical structure, having a first end face 212 and a second end face 214 arranged axially opposite each other, and a side surface 216 connecting the first end face 212 and the second end face 214, with the side surface 216 circumferentially surrounding the first end face 212 and the second end face 214. The piston wall 21 has a connecting hole 218 extending axially from the first end face 212 to the second end face 214, and the central axis of the connecting hole 218 coincides with the central axis of the piston wall 21. It is understood that the shape of the piston wall 21 is not limited to this; in other embodiments, the piston wall 21 may have a frustum shape, a cube shape, or other regular or irregular shapes.

[0044] Furthermore, the first end face 212 of the piston wall 21 is provided with a liquid inlet groove 2121. One end of the liquid inlet groove 2121 is connected to the connecting hole 218, and the other end of the liquid inlet groove 2121 extends away from the connecting hole 218 to connect to the liquid outlet of the liquid storage tank 60. Therefore, the aerosol generation matrix in the liquid storage tank 60 can flow into the connecting hole 218 through the liquid inlet groove 2121.

[0045] In a preferred embodiment, one end of the liquid inlet groove 2121 is connected to the connecting hole 218, and the other end of the liquid inlet groove 2121 extends radially along the connecting hole 218 to the edge of the first end face 212 and connects to the side surface 216. The shape of the cross-section of the liquid inlet groove 2121 perpendicular to its extension direction can be a regular or irregular shape such as a semi-circle, rectangle, or trapezoid. It is understood that the extension direction and cross-sectional shape of the liquid inlet groove 2121 are not limited and can be set as needed to meet different requirements.

[0046] The magnetostrictive element 23 is located on one side of the second end face 214 of the piston wall 21 in the axial direction of the connecting hole 218. The magnetostrictive element 23 has a cylindrical structure, and its central axis coincides with the central axis of the connecting hole 218. The magnetostrictive element 23 is formed of a magnetostrictive material and can be magnetized in a magnetic field and deform in its axial direction (i.e., in the axial direction of the connecting hole 218) to elongate or shorten. Specifically, when the magnetostrictive element 23 elongates, the distance between the end face of the magnetostrictive element 23 facing the piston wall 21 and the second end face 214 of the piston wall 21 decreases or even abuts against the second end face 214; when the magnetostrictive element 23 shortens, the distance between its end face facing the piston wall 21 and the second end face 214 of the piston wall 21 increases.

[0047] The piston rod 27 has a cylindrical structure, and its outer diameter matches the inner diameter of the connecting hole 218 in the piston wall 21. One end of the piston rod 27 is fixed to the magnetostrictive element 23, and the other end extends axially into the connecting hole 218. When the magnetostrictive element 23 deforms and elongates or shortens under the action of a magnetic field, the piston rod 27 reciprocates axially along the connecting hole 218 under the drive of the magnetostrictive element 23. Specifically, when the magnetostrictive element 23 elongates, the piston rod 27 moves toward the first end face 212 of the piston wall 21; when the magnetostrictive element 23 shortens, the piston rod 27 moves toward the second end face 214 of the piston wall 21.

[0048] The microporous screen 29 has a mesh structure. The microporous screen 29 is located on the first end face 212 of the piston wall 21 away from the magnetostrictive member 23 and is correspondingly arranged with the connecting hole 218. The orthographic projection of the microporous screen 29 on the first end face 212 completely covers the connecting hole 218. The microporous screen 29 has micropores with a pore size of 1μm-10μm distributed on it, which are used to control the particle size of the atomized aerosol.

[0049] Thus, the extension and retraction of the magnetostrictive element 23 can drive the piston rod 27 to move closer to or further away from the microporous screen 29 along the axial direction of the connecting hole 218. For example... Figure 2 As shown, when the magnetostrictive element 23 shortens axially under the action of a magnetic field, the piston rod 27 moves away from the microporous screen 29, and the aerosol generation matrix enters the connecting hole 218 along the liquid inlet groove 2121. Figure 3 As shown, when the magnetostrictive component 23 elongates axially under the action of a magnetic field, the piston rod 27 moves toward the direction of the microporous screen 29, squeezing the aerosol generating matrix in the connecting hole 218 through the microporous screen 29. After the aerosol generating matrix with a certain initial velocity passes through the micropores on the microporous screen 29, it is refined to form aerosols of the target particle size.

[0050] In a preferred embodiment, when the piston rod 27 moves to its limit position in the direction close to the microporous screen 29, the end face of the piston rod 27 facing the microporous screen 29 is flush with the first end face 212 of the piston wall 21 where the microporous screen 29 is located. This allows the aerosol generating matrix in the connecting hole 218 to be sufficiently pushed to the microporous screen 29 without damaging the microporous screen 29. It can be understood that the aforementioned "limit position" refers to the position of the piston rod 27 in the connecting hole 218 when the magnetostrictive member 23 is axially extended to its maximum length under the action of a magnetic field.

[0051] like Figure 5As shown, in some embodiments, the piston wall 21 is also provided with a return fluid groove 2123. One end of the return fluid groove 2123 is connected to the connecting hole 218, and the other end of the return fluid groove 2123 is connected to the storage tank 60. Specifically, the return fluid groove 2123 includes a first return fluid section 2123a and a second return fluid section 2123b. The first return fluid section 2123a and the inlet fluid groove 2121 are located on opposite sides of the connecting hole 218 in a radial direction. One end of the first return fluid section 2123a is connected to the connecting hole 218, and the other end of the first return fluid section 2123a extends radially along the connecting hole 218 toward the edge of the first end face 212 and connects to the side surface 216. The second return fluid section 2123b is provided on the side surface 216. One end of the second return fluid section 2123b is connected to the first return fluid section 2123a, and the other end of the second return fluid section 2123b extends circumferentially along the side surface 216 until it connects to the storage tank 80. The shape of the cross-section of the return tank 2123 perpendicular to its extension direction is not limited, and can be a regular or irregular shape such as a circle, a semi-circle, a rectangle, or a trapezoid.

[0052] Thus, when the piston rod 27 pushes the aerosol generating matrix in the connecting hole 218 to the microporous screen 29, the excess aerosol generating matrix that does not pass through the microporous screen 29 can enter the return tank 2123, and then flow back to the storage tank 80 for recycling through the capillary action of the return tank 2123.

[0053] In some embodiments, the piston wall 21 can be controlled to rotate about the central axis of the connecting hole 218 (i.e., the central axis of the piston rod 27) to align the inlet groove 2121 with the outlet of the storage tank 60, thereby controlling the dosage of the aerosol generating matrix entering the connecting hole 218. Specifically, when the atomizing device 100 is not used, the piston wall 21 can be controlled to rotate until the inlet groove 2121 is misaligned with the outlet of the storage tank 60, and the outlet of the storage tank 60 is blocked by the side surface 216 of the piston wall 21, preventing the aerosol generating matrix in the storage tank 80 from flowing into the connecting hole 218. When the atomizing device 100 is required, the piston wall 21 can be controlled to rotate until the inlet groove 2121 is aligned with the outlet of the storage tank 60, allowing the aerosol generating matrix in the storage tank 80 to flow smoothly into the connecting hole 218.

[0054] In some embodiments, the atomizer 20 further includes a coil 25, which is wound around the magnetostrictive member 23 and extends from one axial end of the magnetostrictive member 23 to the other axial end of the magnetostrictive member 23. The coil 25 can generate a magnetic field under the action of electrical energy, thereby causing the magnetostrictive member 23 to deform and shorten or lengthen in the axial direction.

[0055] like Figure 1As shown, in some embodiments, when the atomizing device 100 is placed at the normal operating angle, the piston wall 21 extends axially in the horizontal direction, the liquid storage chamber 60 is located above the atomizer 20, and the liquid outlet of the liquid storage chamber 60 is opened on one side of the bottom of the liquid storage chamber 60. Therefore, the aerosol generating matrix in the liquid storage chamber 60 flows downward along the liquid inlet groove 2121 under the action of gravity to enter the connecting hole 218, and the piston rod 27 moves back and forth in the horizontal direction to push the aerosol generating matrix in the connecting hole 218 through the microporous screen 29.

[0056] like Figure 6 As shown, in some other embodiments, when the atomizing device 100 is placed at the normal operating angle, the piston wall 21 extends axially in a generally vertical direction. In the radial direction of the connecting hole 218, the liquid storage chamber 60 is located on one side of the atomizer 20. The liquid outlet of the liquid storage chamber 60 is opened at the bottom of the liquid storage chamber 60 facing the atomizer 20. Under the action of gravity, the aerosol generating matrix in the liquid storage chamber 60 flows into the connecting hole 218 along the liquid inlet groove 2121. The piston rod 27 moves back and forth in the vertical direction to push the aerosol generating matrix in the connecting hole 218 through the microporous screen 29.

[0057] Further in the above embodiments, the atomizing device 100 also includes an atomizing nozzle 80. The atomizing nozzle 80 is disposed on the side of the microporous screen 29 away from the piston wall 21 and on the horizontal side of the liquid storage tank 60. The atomizing nozzle 80 includes an inlet end communicating with the microporous screen 29 and an outlet end located above the inlet end. The inner diameter of the atomizing nozzle 80 gradually increases from the inlet end to the outlet end. Aerosol passing through the microporous screen 29 can be sprayed upward through the atomizing nozzle 80. It is understood that the shape of the atomizing nozzle 80 is not limited and can be trumpet-shaped, hemispherical, cubic, or other shapes.

[0058] In a preferred embodiment, the bottom wall of the liquid storage tank 60 is lower than the horizontal plane of the inlet tank 2121 in the direction of gravity, thus giving the liquid storage tank 60 a larger volume. Furthermore, to ensure sufficient outflow of the aerosol-generating matrix from the liquid storage tank 60, such as... Figure 7 As shown, in the direction of gravity, the edge of the outlet end of the atomizing nozzle 80 extends downward at an angle from the side closest to the liquid storage tank 60 toward the side furthest from the liquid storage tank 60. Thus, the shape of the atomizing nozzle 80 guides the user to tilt the atomizing device 100 downward appropriately during use, allowing the aerosol generating matrix in the liquid storage tank 60 to flow fully into the atomizing device 100, reducing the amount of aerosol generating matrix remaining in the liquid storage tank 60, and improving atomization efficiency.

[0059] Please see Figure 6 In some embodiments, the top of the liquid storage tank 60 is also provided with an injection port 61, through which the user can add aerosol generation matrix to the liquid storage tank 60.

[0060] The aforementioned atomizer 20 and atomizing device 100 utilize the characteristic of the magnetostrictive element 23 expanding and contracting under the influence of a magnetic field to drive the reciprocating movement of the piston rod 27 relative to the microporous sieve 29, thereby achieving atomization of the aerosol generation matrix. This achieves an energy conversion efficiency of up to 70%, generates significant kinetic energy, exhibits good resistance to thermal aging, and provides excellent atomization for high-viscosity liquids. Furthermore, because the aerosol generation matrix is ​​pushed by the piston rod 27 without directly contacting the magnetostrictive element 23, the risk of heavy metal ion precipitation is reduced, improving the safety of the atomizing device 100. In addition, the microporous sieve 29 allows for selectivity in aerosol particle size, meeting diverse user needs.

[0061] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0062] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
