[0079] The exemplary embodiments will be described in detail herein with reference to the attached drawings. In the following description, like reference numerals refer to like elements, unless the context clearly dictates otherwise. The following description is not meant to limit the application to all of the embodiments described herein. Rather, the following description is meant to provide examples of methods and apparatuses consistent with the application as detailed in the following claims.

[0080] The terms "first", "second", "third", "fourth" and the like in the description and in the claims, where they occur, are used as labels for nouns that they precede, and do not necessarily describe a relationship with, or order of, such terms. It should be understood that the use of such terms is merely for convenience and does not necessarily imply a particular order, unless explicitly stated otherwise. Furthermore, the terms "include", "have", and the like, when used in the description and in the claims, are intended to be inclusive in a manner similar to the term "comprise" as an open transition modifier, followed by a transition word, phrase or term that limits a particular step, operation, action, etc., to the steps, operations, actions, etc. specifically referenced by the transition word, phrase or term, unless otherwise indicated. Thus, use of such terms in the claims is not intended to exclude other steps, operations, actions, etc. from the claimed application.

[0081] As mentioned in the background section, at present, the micropores on the atomization sheet are mostly generated by laser drilling. Due to technical limitations, the diameter of the drilled micropores is usually 3-5 μm, and it is difficult to drill micropores with a smaller diameter. Since the diameter of the micropores is still relatively large, the particle size of the atomized droplets is large. When the patient uses the atomizer for smoking, the impact of the large-particle-size droplets on the throat is strong, and the discomfort is strong, thereby affecting the use experience.

[0082] In view of the above problems existing in the prior art, the present application provides an atomization sheet, an atomization assembly and an atomizer. The atomization sheet provided by the present application comprises a substrate and a film coating layer. A plurality of first micropores are formed on the substrate to form reference holes. The film coating layer is arranged on at least part of the inner wall of each first micropore to reduce the size of each first micropore to form a second micropore. The thickness of the film coating layer is controlled to control the reduction degree of the first micropore, so that the particle size of the atomized droplets is smaller, thereby improving the use experience.

[0083] The technical solutions of the present application will be described in detail below with specific examples. The following specific examples can be combined with each other, and the same or similar concepts or processes may not be described in detail in some examples.

[0084] In a first aspect, referring to Figures 1-10 The atomization assembly provided by the embodiments of the present application comprises a substrate 100 and a film coating layer 200. A plurality of first micropores 110 are formed on the substrate 100.

[0085] The film coating layer 200 is arranged on at least part of the inner wall of each first micropore 110 to reduce the size of each first micropore 110 to form a second micropore 210.

[0086] The substrate 100 in the embodiment is used for vibration to generate atomization, which can be a sheet or a plate structure, such as a stainless steel sheet. A plurality of first micropores 110 are formed on the substrate 100. The first micropores 110 can be cylindrical holes, square holes, inverted conical holes, etc.

[0087] The film coating layer 200 in the embodiment is used for reducing the size of each first micropore 110. It can be adhered to the inner wall of each first micropore 110 by gold plating, aluminum plating or titanium plating, so as to reduce the diameter of each first micropore 110 to form a second micropore 210. The thicker the film coating layer 200 is, the smaller the diameter of the second micropore 210 is.

[0088] Specifically, as Figure 1As shown, several first micropores 110 with a diameter of 3~5μm or larger can be drilled on the substrate 100 using a laser. Then, through a coating process, a coating layer 200 with a thickness of 0.25μm~1.5μm is formed on a portion of the inner wall of each first micropore 110. The minimum pore diameter of the second micropore 210 is Φ, and the thickness of the coating layer 200 is H. As H increases, Φ decreases accordingly. In this way, when the substrate 100 vibrates, the particle size of the atomized liquid passing through the second micropore 210 is smaller, reducing the impact and discomfort caused by large droplets, thereby improving the user experience.

[0089] Moreover, the process of first laser drilling and then coating results in better product consistency, better cost control, and facilitates mass production.

[0090] The coating process generally includes five steps: cleaning, applying a protective film, coating, cleaning again, and removing the protective film, as detailed below:

[0091] Step 1, such as Figure 2 As shown in (a), the surface of the substrate 100 with the first micropore 110 made is cleaned with anhydrous ethanol and deionized water in sequence to remove particles and oil stains.

[0092] Step 2, as follows Figure 2 As shown in (b), a protective film is used to cover the periphery of the substrate 100 or the periphery of the substrate 100 together with the piezoelectric ceramic thereon to prevent damage to the piezoelectric ceramic during the coating process. The protective film can be a polyimide film or a polymer film such as polyethylene terephthalate.

[0093] Step 3, as follows Figure 2 As shown in (c), the substrate 100 is coated using methods such as electroplating, magnetron sputtering, and chemical vapor deposition. The coating surface can be the inlet side.

[0094] Step 4, such as Figure 2 As shown in (d), the substrate 100 after coating is cleaned with anhydrous ethanol and deionized water to remove residual stains from the coating.

[0095] Step 5, as Figure 2 As shown in (e), the protective film is removed to obtain a substrate 100 with a reduced pore size. The pore size of the second micropore 210 can be controlled by adjusting the thickness of the coating layer 200.

[0096] Therefore, the atomizing component provided in this application embodiment includes a substrate 100 and a coating layer 200. By forming a plurality of first micropores 110 on the substrate 100 to form reference holes, and then disposing of the coating layer 200 on at least a portion of the inner wall of each first micropore 110, the first micropores 110 are reduced to form second micropores 210. By controlling the thickness of the coating layer 200, the degree of reduction of the first micropores 110 is controlled, so that the atomized droplets have a smaller particle size, thereby improving the user experience.

[0097] In one possible design, the aperture of the first microorifice 110 on the inlet side is larger than the aperture on the outlet side. Further, the aperture of the first microorifice 110 gradually decreases from the inlet side to the outlet side.

[0098] That is, such as Figure 1 As shown, Figure 1 The upper surface of the middle is the inlet side. Figure 1 The lower surface of the droplet is the outlet side. As the droplet passes through each of the second micro-holes 210 from top to bottom, it is sprayed out under pressure, resulting in better atomization. In particular, the diameter of the first micro-hole 110 gradually decreases from the inlet side to the outlet side. That is, the first micro-hole 110 is an inverted conical hole, which can be sprayed out under uniform pressure.

[0099] The specific difference between the inlet diameter and the outlet diameter of the first micro-orifice 110, i.e., the taper of the first micro-orifice 110, can be determined according to actual needs, and is not specifically limited in this embodiment.

[0100] Furthermore, in this embodiment, the diameter of the second micropore 210 on the outlet side of the first micropore 110 is 1μm~5μm.

[0101] That is, such as Figure 1 As shown, the minimum pore size Φ of the second micropore 210 is 1μm to 5μm. The specific value of Φ can be determined according to actual needs, and is not limited in this embodiment.

[0102] In some embodiments, the thickness of the coating layer 200 is 0.25 μm to 1.5 μm.

[0103] That is, such as Figure 1 As shown, since the thickness of the single-layer coating 200 is 0.25μm~1.5μm, the thickness of the double-layer coating 200 in the first micropore 110 is 0.5μm~3μm. The specific thickness of the coating 200 can be determined according to actual needs, and is not limited in this embodiment.

[0104] In some embodiments, the substrate 100 is a stainless steel sheet. And / or, the coating layer 200 is one of a nickel layer, a chromium layer, a copper layer, a gold layer, an aluminum layer, and a titanium layer.

[0105] Specifically, the stainless steel sheet has good elasticity, and nickel, chromium, copper, gold, aluminum and titanium can be easily plated on the stainless steel sheet. The thickness of the stainless steel sheet and the specific metal to be plated can be determined according to actual needs, and the present embodiment does not make too many limitations.

[0106] In some embodiments, the film layer 200 is also arranged on at least one side surface of the substrate 100.

[0107] That is, as shown in Figure 1 the film layer 200 is arranged on the upper surface of the substrate 100 and in each first micro-hole 110, so that the thickness of the film layer 200 can be easily controlled, and mass production can be facilitated.

[0108] In a second aspect, the present embodiment also provides an atomization assembly, which comprises a driving member 300 and the atomization sheet provided in any of the above embodiments. The driving member 300 is connected with the substrate 100.

[0109] The driving member 300 is configured to drive the substrate 100 to vibrate when the atomized liquid passes through each second micro-hole 210, so as to atomize the atomized liquid.

[0110] In this way, the driving member 300 is connected with the substrate 100 as a whole, which facilitates the next assembly.

[0111] The structure of the atomization sheet is described in detail in the above embodiments, and will not be repeated here.

[0112] The atomization assembly provided by the present embodiment comprises the atomization sheet, which comprises the substrate 100 and the film layer 200. A plurality of first micro-holes 110 are formed on the substrate 100 to form reference holes. The film layer 200 is arranged on at least part of the inner wall of each first micro-hole 110 to reduce the size of each first micro-hole 110 to form a second micro-hole 210. The thickness of the film layer 200 is controlled to control the reduction degree of the first micro-hole 110, so that the particle size of the atomized droplets is smaller, thereby improving the user experience.

[0113] For example, in the present embodiment, the driving member 300 is a piezoelectric ceramic and is connected to the peripheral side of the substrate 100.

[0114] The driving member 300 has a through hole 310, which communicates with each second micro-hole 210.

[0115] Specifically, as shown in Figure 3 the piezoelectric ceramic has the same shape as the substrate 100. It can be connected to one side surface of the substrate 100 by adhesion, pressure bonding or the like. The substrate 100 and the piezoelectric ceramic are respectively connected with lead wires, which are not shown in the figure, so that the piezoelectric ceramic deforms to drive the substrate 100 to vibrate when electrified.

[0116] The middle part of the piezoelectric ceramic further has a through hole 310 to avoid interference with the atomized liquid passing through the second micropores 210. The specific model, specification, etc. of the piezoelectric ceramic can be determined according to actual needs, and the present embodiment does not make too many limitations.

[0117] In a third aspect, the present embodiment further provides an atomizer, comprising an atomizer body, and the atomizer body is provided with the atomization assembly provided in any of the above embodiments.

[0118] The atomizer provided in the present embodiment is configured with the atomization assembly, the atomization assembly comprises an atomization sheet, the atomization sheet comprises a substrate 100 and a plating layer 200, a plurality of first micropores 110 are formed on the substrate 100 to form reference holes, and the plating layer 200 is arranged on at least part of the inner wall of each first micropore 110 to reduce the first micropore 110 to form a second micropore 210. The thickness of the plating layer 200 is controlled to control the reduction degree of the first micropore 110, so that the particle size of the liquid droplets formed by atomization is smaller, thereby improving the use experience.

[0119] In some embodiments, the atomizer body comprises:

[0120] The shell assembly 400 has a mounting cavity 401 therein, and the shell assembly 400 has an atomization outlet 402 and at least one liquid supply port 403. The substrate 100 and the driving member 300 are arranged at the liquid supply port 403.

[0121] The gas distribution member 500 is arranged in the mounting cavity 401, and the gas distribution member 500 has at least one gas-liquid passage 510. One side of the gas-liquid passage 510 is in communication with the atomization outlet 402, and the other side of the gas-liquid passage 510 is in communication with the liquid supply port 403 through the second micropores 210 on the substrate 100.

[0122] The liquid storage member 600 is arranged on the shell assembly 400 and is in communication with the liquid supply port 403, and is used to provide atomized liquid.

[0123] The control member 700 is arranged in the mounting cavity 401 and is electrically connected with the driving member 300. The control member 700 is configured to control the driving member 300 to drive the substrate 100 to vibrate when the atomized liquid in the liquid storage member 600 enters the second micropore 210 through the liquid supply port 403 under the action of pressure, so that the atomized liquid forms an aerosol, and the aerosol is discharged from the atomization outlet 402 after passing through the gas-liquid passage 510.

[0124] Specifically, as Figure 4 , Figure 5 , Figure 6As shown, the shell assembly 400 can be a cuboid structure, the air distribution member 500 is embedded in the mounting cavity 401, the gas-liquid channel 510 on the air distribution member 500 is communicated with the mist outlet 402 on one side, and communicated with the liquid supply port 403 through each second micropore 210 on the substrate 100 on the other side, so that the liquid supply port 403, each second micropore 210, the gas-liquid channel 510 and the mist outlet 402 form an atomization channel.

[0125] It should be noted that, as Figure 6 shown, the atomization assembly is installed between the air distribution member 500 and the liquid supply port 403, and a sealing ring can be sleeved on the peripheral side of the substrate 100 of the atomization assembly and the driving member 300, one end surface of the sealing ring abuts against the air distribution member 500, and the other end surface of the sealing ring abuts against the inner wall of the mounting cavity 401, which not only ensures the sealing property, but also eliminates the vibration influence of the atomization assembly.

[0126] The liquid storage member 600 can be a box shell structure, which is used to hold the atomization liquid, and the liquid storage member 600 can be connected to the shell assembly 400 by plug-in, screwing, stop connection and the like, so that the liquid storage member 600 can be detachably connected to the shell assembly 400, and after the atomization liquid is consumed, it is convenient to refill or replace. The liquid storage member 600 can be provided with a liquid outlet corresponding to the liquid supply port 403, and a sealing ring can be further provided between the liquid outlet and the liquid supply port 403 to prevent liquid leakage.

[0127] The control member 700, i.e. the circuit board and the control module provided on the circuit board, is used to control the action of the driving member 300. More specifically, when a negative pressure is provided at the mist outlet 402, such as suction is performed on the mist outlet 402, or when the atomization liquid in the liquid storage member 600 is caused to enter the second micropore 210 through the liquid supply port 403 by providing a positive pressure in the liquid storage member 600, the control member 700 controls the driving member 300 to drive the substrate 100 to vibrate, so that the atomization liquid forms an aerosol, and the aerosol is discharged from the mist outlet 402 after passing through the gas-liquid channel 510, which is subsequently used by the user. The structure of the atomizer is compact, and is convenient for processing, assembling and the like.

[0128] Further, in the embodiment, the gas-liquid channel 510 includes a first flow channel 511, a chamber 512 and a second flow channel 513, the liquid supply port 403 is communicated with the chamber 512 through the first flow channel 511, and the chamber 512 is communicated with the mist outlet 402 through the second flow channel 513.

[0129] In this way, as Figure 7 shown, the chamber 512 is roughly in the shape of a trapezoid, and the area thereof is much larger than the areas of the first flow channel 511 and the second flow channel 513, so as to facilitate the subsequent installation of filtering, flow blocking and the like components in the chamber 512.

[0130] Further, in the embodiment, the chamber 512 has opposite first and second inner walls 501 and 502, and the air distribution member 500 is provided with a barrier 520.

[0131] The barrier 520 is connected to at least one of the first and second inner walls 501 and 502, so that the chamber 512 forms a tortuous flow channel.

[0132] Specifically, as shown in Figure 7 , the barrier 520 is used to block the aerosol in the chamber 512, so as to prolong the path of the aerosol, collect large-sized droplets, and make the droplets in the aerosol smaller. The barrier 520 can make the chamber 512 form a tortuous flow channel, such as a labyrinth type.

[0133] Further, in the embodiment, the first flow channel 511 and the chamber 512 form a first slit, and the width W1 of the first slit is 2-4 mm.

[0134] In addition, the second flow channel 513 and the outlet 402 form a second slit, and the width W2 of the second slit is 2-4 mm.

[0135] In this way, as shown in Figure 7 , the width of the slit is controlled to control the resistance of the suction. The specific size of the first and second slits can be determined according to actual needs, and the embodiment is not limited too much.

[0136] In some embodiments, the air distribution member 500 is provided with a filter 530, which is located in the chamber 512 and is used to filter droplets of a predetermined size in the aerosol.

[0137] In this way, as shown in Figure 7 , the filter 530 filters out large-sized droplets in the aerosol, further reducing the impact of the suction.

[0138] Further, in the embodiment, the filter 530 includes a first filter plate 531 and a second filter plate 532. The first filter plate 531 is located between the barrier 520 and the first flow channel 511 and is used to filter droplets of a first predetermined size.

[0139] The second filter plate 532 is located between the barrier 520 and the second flow channel 513 and is used to filter droplets of a second predetermined size. The first predetermined size is greater than or equal to the second predetermined size.

[0140] Specifically, as shown in Figure 7 , Figure 8 , Figure 9As shown, the first filter plate 531 is used to filter large-particle-size droplets, which is close to the liquid inlet 403, and the second filter plate 532 is used to filter medium-particle-size droplets, which is close to the mist outlet 402. Through the action of the two layers of filter plates and the blocking part 520, most of the large-particle-size droplets in the aerosol are eliminated, and the atomization quality is ensured.

[0141] The specific sizes of the first preset particle size and the second preset particle size can be determined according to actual needs, and are not limited in the embodiment.

[0142] Further, in the embodiment, a plurality of first screen holes 5311 are arranged on the first filter plate 531 at intervals, and the diameter R1 of the first screen hole 5311 is the first preset particle size, which can be 1mm-2mm.

[0143] A plurality of second screen holes 5321 are arranged on the second filter plate 532 at intervals, and the diameter R2 of the second screen hole 5321 is the second preset particle size, which can be 0.5mm-1mm.

[0144] Specifically, as shown in Figure 8 , Figure 9 The first screen hole 5311 and the second screen hole 5321 can be round holes, square holes, special-shaped holes, etc., and both can be arranged in a rectangular array or a circular array. The specific number and specific size of the diameter of the first screen hole 5311 and the second screen hole 5321 can be determined according to actual needs, and are not limited in the embodiment.

[0145] Further, in the embodiment, each first screen hole 5311 is arranged at intervals along the first direction and the second direction, respectively, and the pitch L1 of adjacent first screen holes 5311 along the first direction is 0.8mm-1.6mm, and the pitch L2 of adjacent first screen holes 5311 along the second direction is 0.6mm-1.2mm. The first direction is perpendicular to the second direction.

[0146] And / or, each second screen hole 5321 is arranged at intervals along the third direction and the fourth direction, respectively, and the pitch L3 of adjacent second screen holes 5321 along the third direction is 0.6mm-1.2mm, and the pitch L4 of adjacent second screen holes 5321 along the fourth direction is 0.75mm-1.5mm. The third direction is perpendicular to the fourth direction.

[0147] That is, as shown in Figure 8 Each first screen hole 5311 is arranged in a rectangular array on the first filter plate 531, the first direction is as shown along the X-axis direction in Figure 8 , and the second direction is as shown along the Y-axis direction in Figure 8 .

[0148] Similarly, as shown in Figure 9As shown, each of the second sieve holes 5321 is arranged in a rectangular array on the second filter plate 532, with the third direction as along... Figure 9 As shown in the X-axis direction, the fourth direction is as follows: Figure 9 As shown in the Y-axis direction.

[0149] The spacing between each first sieve hole 5311 and the spacing between each second sieve hole 5321 can be determined according to actual needs, and no restrictions are imposed in this embodiment.

[0150] In some embodiments, the partition portion 520 includes a protrusion 521 and a first partition 522, the protrusion 521 and the first partition 522 being arranged at intervals along the direction from the first flow channel 511 to the second flow channel 513.

[0151] One side of the protrusion 521 is connected to the first inner wall 501, and the other side extends toward the second inner wall 502. One side of the first partition 522 is connected to the second inner wall 502, and the other side extends toward the first inner wall 501.

[0152] Specifically, such as Figure 7 As shown, when the aerosol passes through the protrusion 521 and the first partition 522 in sequence, the obstruction effect of the two protrusions lengthens the path and slows down the flow rate, making it easier to collect large-diameter droplets. Of course, more protrusions 521 and first partitions 522 can be provided, but this embodiment does not impose too many restrictions on this.

[0153] Furthermore, in this embodiment, a third slit is formed between the protrusion 521 and the second inner wall 502. The width W3 of the third slit is 1mm to 3mm. When the first slit is formed at the connection between the first flow channel 511 and the chamber 512, the width W3 of the third slit is less than the width W1 of the first slit.

[0154] A fourth slit is formed between the first partition 522 and the first inner wall 501. The width W4 of the fourth slit is 1mm to 2mm, and the width W4 of the fourth slit is less than the width W3 of the third slit.

[0155] Specifically, continue as Figure 7 As shown, by controlling the widths W3 and W4 of the third and fourth slits, the flow velocity of the aerosol at the third and fourth slits can be accurately controlled. Furthermore, this ensures that the resistance of the aerosol in chamber 512 increases sequentially, achieving better collection of large-diameter droplets. The specific sizes of the widths W3 and W4 of the third and fourth slits can be determined according to actual needs; this embodiment does not impose excessive restrictions.

[0156] It should be noted that the upper surface of the protrusion 521 on the side close to the third slit is inclined towards the first flow channel 511 to avoid droplet accumulation. Similarly, the upper surface of the first partition 522 on the side close to the fourth slit is inclined towards the first flow channel 511 to avoid droplet accumulation. Similarly, the bottom surface of the chamber 512 on the side close to the first slit is inclined towards the first flow channel 511 to avoid droplet accumulation.

[0157] In other embodiments, the barrier 520 includes a second partition 523, a third partition 524 and a fourth partition 525, which are sequentially and spaced apart along the direction from the first flow channel 511 to the second flow channel 513.

[0158] One side of the second partition 523 is connected to the first inner wall 501, and the other side extends towards the second inner wall 502. One side of the third partition 524 is connected to the second inner wall 502, and the other side extends towards the first inner wall 501. One side of the fourth partition 525 is connected to the first inner wall 501, and the other side extends towards the second inner wall 502.

[0159] Specifically, as shown in Figure 10 the aerosol sequentially passes through the second partition 523, the third partition 524 and the fourth partition 525, the path is lengthened under the blocking action of the three, the flow rate is slowed down, and large-particle-size droplets are facilitated to be collected. Of course, a larger number of second partitions 523, third partitions 524 and fourth partitions 525 can also be provided, and the present embodiment does not make too many limitations thereon.

[0160] Further, in the present embodiment, the second partition 523 and the second inner wall 502 form a fifth slit therebetween, and the width W5 of the fifth slit is 1mm-3mm. When the first flow channel 511 and the chamber 512 form the first slit at the communication position, the width W5 of the fifth slit is smaller than the width W1 of the first slit.

[0161] The third partition 524 and the first inner wall 501 form a sixth slit therebetween, and the width W6 of the sixth slit is 1mm-2mm, and the width W6 of the sixth slit is smaller than the width W5 of the fifth slit.

[0162] The fourth partition 525 and the second inner wall 502 form a seventh slit therebetween, and the width W7 of the seventh slit is 0.8mm-1.6mm, and the width W7 of the seventh slit is smaller than the width W6 of the sixth slit.

[0163] Specifically, continuing as shown in Figure 10As shown, the flow rate of the aerosol passing through the fifth slit, the sixth slit and the seventh slit is accurately controlled by controlling the width W5 of the fifth slit, the width W6 of the sixth slit and the width W7 of the seventh slit. Moreover, the resistance of the aerosol in the chamber 512 is ensured to increase in turn, achieving a better effect of collecting large-diameter droplets. The specific sizes of the width W5 of the fifth slit, the width W6 of the sixth slit and the width W7 of the seventh slit can be determined according to actual needs, and are not limited in the embodiment.

[0164] It should be noted that the upper surface of the second partition plate 523 near the fifth slit is inclined toward the first flow channel 511 to avoid droplet aggregation. Similarly, the upper surface of the third partition plate 524 near the sixth slit is inclined toward the first flow channel 511 to avoid droplet aggregation. Similarly, the upper surface of the fourth partition plate 525 near the seventh slit is inclined toward the first flow channel 511 to avoid droplet aggregation.

[0166] One side of the two gas-liquid channels 510 is in communication with the mist outlet 402, and the other side of the two gas-liquid channels 510 is in communication with the two liquid supply ports 403 through the second micropores 210 on the two substrates 100, respectively.

[0170] The control member 700 is further configured to control the heating member 800 to heat the accumulated droplets in the gas-liquid channel 510 every preset time length, so that the droplets are evaporated.

[0171] Specifically, as shown in Figure 5 , Figure 6 , the heating member 800 can be a polyimide heating film. When the atomizer is used for a period of time, the droplets flowing back to the bottom can be evaporated by the heating member 800 to prevent blockage. The specific type and structure of the heating member 800 can be determined according to actual needs, and are not limited in the embodiment.
