Referring to fig. 1, an atomization apparatus 1000 is disclosed in an embodiment of the present application, where the atomization apparatus 1000 is an apparatus for forming an aerosol from an atomized substrate by heating or the like. The atomizing apparatus 1000 includes a host computer 200 and an atomizing device 100. The atomizing device 100 is connected to a host 200. The host 200 may provide power to the aerosolization device 100. It should be noted that the atomizing substrate used in the embodiments of the present application may be an aerosol-forming liquid. In addition, the nebulized matrix may also be a medical nebulizing agent or other type of nebulized matrix. Embodiments of the present application are not limited to a particular type of nebulized substrate. The user can inhale the atomized aerosol through oral inhalation or nasal inhalation and the like.

The nebulized matrix of embodiments of the present application may be a high viscosity nebulized matrix, which may have a viscosity of greater than 10000cps at ambient temperature (25 ℃). In an embodiment of the present application, the viscosity measurement method is as follows: GBT 17473.5-1998 thick film microelectronics was viscometric using noble metal paste testing.

Referring to fig. 2-3, an atomizing device 100 according to an embodiment of the present disclosure includes a housing 10 and an atomizing core 20, the atomizing core 20 being mounted within the housing 10. In particular, the housing 10 is also a basic component of the atomizing device 100, and the housing 10 may carry other parts of the atomizing device 100. The housing 10 is formed with a liquid storage chamber 11, and the atomized substrate is accommodated in the liquid storage chamber 11. The atomizing core 20 is a component for forming an aerosol from an atomized matrix. The atomizing core 20 may atomize the atomizing substrate to form a mist by heating.

Referring to fig. 3-4, in some embodiments, the atomizing core 20 includes a mounting base 21 and a heat generating body 22, the heat generating body 22 being disposed on the mounting base 21. Specifically, the mounting seat 21 is a component for fixing the heating element 22, and the mounting seat 21 has the functions of bearing the heating element 22, blocking the liquid storage chamber 11, and the like. The heat generating body 22 is a component for generating heat and atomizing the atomized substrate.

As shown in fig. 4, the mount 21 is provided with a lower liquid passage 211 and a mist outlet passage 213, the lower liquid passage 211 being a passage through which the atomized substrate flows from the liquid storage chamber 11 to the heat generating body 22. The atomized substrate enters the lower liquid channel 211 from one end of the lower liquid channel 211 and flows to the heating element 22 from the other end of the lower liquid channel 211 under the action of gravity, air pressure and the like.

The mist outlet passage 213 is a passage for guiding out the mist such as the aerosol formed by atomizing the atomized substrate heated by the heating element 22 to the outside of the mount 21, or the aerosol formed by atomizing the substrate can flow out of the mount 21 through the mist outlet passage 213.

The mist outlet duct 213 and the lower liquid duct 211 are disposed to intersect and be isolated from each other, for example, the lower liquid duct 211 is disposed on a first side of the mount 21, the mist outlet duct 213 is disposed on a second side of the mount 21, and the first side and the second side are perpendicular. As shown in the orientation of fig. 4, the liquid discharge passages 211 are provided on the left and right sides of the mount 21, and the mist discharge passages 213 are provided on the front and rear sides of the mount 21.

It will be appreciated that the mounting base 21 and the heating element 22 are both mounted within the housing 10.

Referring to fig. 5 and 6, in some embodiments, the heat generating body 22 includes a substrate 221 and a heat generating film 222 disposed on the substrate 221. The heat generating body 22 is formed with a slit 223 penetrating the substrate 221 and the heat generating film 222 in the thickness direction of the heat generating film 222.

As such, the width of the slit 223 is smaller, so that the temperature difference of the atomized substrate respectively located at the center of the width of the slit 223 and the edge of the slit 223 is smaller, and the atomized substrate can be atomized more uniformly.

Specifically, the substrate 221 may serve as a carrier for the heat generating film 222. The substrate 221 may be made of glass, dense ceramic, or the like, or the substrate 221 may include a glass substrate 221, a ceramic substrate 221. The specific materials of the substrate 221 are not further limited in this application.

In the case where the substrate 221 is made of glass, the substrate 221 has insulation properties to prevent the entire heat generating body 22 from generating heat to atomize the entire atomized matrix in the liquid storage chamber 11. In addition, the glass substrate 221 is low in material cost and easy to mold, and the manufacturing cost of the heating element 22 can be reduced. The substrate 221 may have a square sheet shape, an oval shape, or the like. In the case where the substrate 221 is in the form of a square sheet, the length and width of the substrate 221 may be 6mm by 3mm, respectively.

The heat generating film 222 is used to convert electric energy into heat energy. The heat generating film 222 may be made of a material which is conductive and easily generates heat, such as metal, alloy, or the like. For example, the material of the heat generating film 222 may be gold, silver, platinum, palladium-copper alloy, gold-silver-platinum alloy, gold-silver alloy, titanium-zirconium alloy, palladium-silver alloy, gold-platinum alloy, stainless steel, or the like. The heating film 222 may be disposed on the surface of the substrate 221 by printing, electroplating, pasting, sputtering, or the like. The slit 223 may be formed by laser processing, etching, or the like.

The cross section referred to herein refers to a plane perpendicular to the thickness of the heat-generating body 22, and the cross sectional area is an area surrounded by the outline of an object or feature in the cross section.

Referring to fig. 7 and 8, in some embodiments, the ratio (L/W) between the length L and the width W of the slit 223 is greater than 2. For example, the aspect ratio of the slit 223 is a number of 3, 10, 50, 100, 200, or the like. Thus, the length L of the slit 223 is much longer than the width W, and in the slit 223 and the circular hole having the same cross-sectional area, the circumference of the slit 223 is longer, so that the atomized substrate is more easily transported to the surface of the heat generating film 222 through the slit 223.

Note that the length L of the slit 223 is the maximum size of the slit 223 in the extended state of the slit 223, and the width W of the slit 223 is the size perpendicular to the central axis 224 of the slit 223.

Referring to fig. 8, in some embodiments, the width of the slit 223 ranges from 5 μm to 200 μm. For example, the width of the slit 223 may range from 5 μm to 150 μm, from 5 μm to 50 μm, from 30 μm to 100 μm, from 50 μm to 80 μm, or the like. As another example, the width W of the slit 223 may be 5 μm, 15 μm, 50 μm, 100 μm, 150 μm, 200 μm, etc. in size.

In the case where the width W of the slit 223 is less than 5 μm, the slit 223 is difficult to form, the heat-generating body 22 is difficult to manufacture, and the atomized substrate is difficult to pass through the slit 223; in the case where the width W of the slit 223 is greater than 200 μm, the width of the slit 223 is large, and the temperature of the center of the width of the slit 223 is easily uneven with the temperature of the edge, and therefore, in the case where the width W of the slit 223 is 5 μm to 200 μm, the slit 223 is not only easy to manufacture, but also the temperature difference of the atomized substrate respectively located at the center of the width of the slit and the edge of the slit can be made small, and the atomized substrate can be atomized more uniformly.

Note that in the same slit 223, the width of the slit 223 may be set to be an equal shape everywhere, and the slit 223 may be set to be an unequal width shape.

Referring to fig. 7 and 8, in some embodiments, the slit 223 has a length in the range of 10 μm to 4000 μm. For example, the slit 223 may have a length ranging from 10 μm to 4000 μm, 500 μm to 3500 μm, 800 μm to 3000 μm, 1000 μm to 2000 μm, or 1200 μm to 1500 μm, etc. For another example, the length L of the slit 223 may be 10 μm, 200 μm, 500 μm, 1000 μm, 2000 μm, 3000 μm, 4000 μm, etc.

In the case where the length L of the slit 223 is less than 10 μm, the liquid discharging ability of the heat-generating body 22 may be insufficient, and the atomized substrate is difficult to be transported to the atomized surface of the heat-generating body 22; if the length L of the slit 223 is larger than 4000 μm, the size of the heating element 22 is required to be large, which tends to increase the overall size of the atomizing device 100, and is disadvantageous in downsizing the atomizing device 100. Therefore, in the case where the length L of the slit 223 is 10 μm to 4000 μm, the liquid discharging ability of the heat generating body 22 is strong, and the size of the heat generating body 22 can be made appropriate, which is advantageous in downsizing the atomizing device 100.

In some embodiments, slit 223 is linear or curvilinear. In the example shown in fig. 7, the slit 223 is in a linear shape, and the linear slit 223 makes the pattern on the surface of the heating film 222 regular, so that the atomized liquid flowing onto the surface of the heating film 222 is more uniform, which is beneficial to improving the uniformity of atomization of the heating body 22. In the example shown in fig. 9, the slit 223 is curved, and the curved slit 223 can adjust the resistance of the heating film 222 and optimize the current path, so that the heating film 222 heats more uniformly, and the uniformity of atomization of the heating body 22 is improved.

Referring to fig. 8, the slit 223 is linear or curved and is defined based on the central axis 224 of the slit 223, and if the central axis 224 of the slit 223 is linear, and if the central axis 224 of the slit 223 is curved, the slit 223 is curved. The curve may be wavy, curved, etc., and the application is not limited to the specific shape of the curve.

In certain embodiments, the number of slits 223 is a plurality, and the shape and/or size of slits 223 are substantially the same. For example, the shape of any two slits 223 is substantially the same; as another example, the dimensions of any two slits 223 are substantially the same; for another example, the shape and size of any two slits 223 are the same. In this way, the uniformity of the arrangement structure of the plurality of slits 223 is better, so that the atomized liquid flowing to the surface of the heating film 222 is more uniform, which is beneficial to improving the uniformity of the atomization of the heating body 22.

As in the example of fig. 7, all slits 223 are rectilinear and have the same dimensions of length, width, etc. As in the example of fig. 9, all slits 223 are curved and have the same dimensions of length, width, etc.

Of course, in some embodiments, the shape of any two slits 223 may be different. For example, the partial slit 223 is linear, and the partial slit 223 is curved. In some embodiments, the dimensions of any two slits 223 may be different. For example, the length of the partial slit 223 is longer, and the length of the partial slit 223 is shorter.

Referring to fig. 6, in some embodiments, a center line 225 of the slit 223 in the depth direction is substantially straight, and the extending direction of the center line 225 is substantially identical to the thickness direction of the heating element 22. In this way, the transport path of the atomized liquid is shorter, and the atomized liquid more easily reaches the surface of the heat generating film 222 through the slit 223 and is atomized.

Of course, in other embodiments, the extending direction of the center line 225 may be inclined with respect to the thickness direction of the heating element 22.

As shown in fig. 7 and 8, in some embodiments, the number of slits 223 is plural, and the plural slits 223 are linearly arranged along the width direction of the slits 223. In this way, the plurality of slits 223 are regularly arranged, so that the atomized liquid flowing to the surface of the heating film 222 is more uniform, which is beneficial to improving the uniformity of atomization of the heating body 22. The number of slits 223 may be determined according to the width of each slit 223, the spacing distance, and the overall size of the heat-generating body 22, and the present application does not limit the specific number of slits 223. Of course, in other embodiments, the plurality of slits 223 may be arranged in an irregular shape.

Referring to fig. 7-9, in some embodiments, the distance between any two adjacent slits 223 is equal. Thus, the amount of the atomized substrate at each position of the heat generating film 222 can be made substantially the same, which is advantageous for improving the uniformity of atomization of the heat generating body 22. Of course, in other embodiments, the distance between any two adjacent slits 223 may not be equal.

In some embodiments, the distance between slits 223 in the middle region of heat-generating body 22 is smaller than the distance between slits 223 in other regions of heat-generating body 22. Thus, the atomization capability of different areas of the heating element 22 can be matched with the slits 223 with different intervals, so that the atomization of the heating element 22 is more uniform.

Referring to fig. 8, in some embodiments, the distance between two adjacent slits 223 is in the range of 10 μm to 100 μm. For example, the distance between two adjacent slits 223 ranges from 10 μm to 100 μm, from 10 μm to 90 μm, from 20 μm to 80 μm, from 30 μm to 75 μm, from 50 μm to 60 μm, etc. For another example, the distance D between two adjacent slits 223 may be 10 μm, 15 μm, 50 μm, 80 μm, 100 μm, or the like.

In the case where the size of the distance D is less than 10 μm, the adjacent slits 223 are easily communicated with each other, so that the heat-generating body 22 is not easily manufactured; in the case where the size of the distance D is more than 100 μm, the distance between the adjacent two slits 223 is excessively large, which easily results in difficulty in transporting the atomized substrate to each position of the heat generating film 222, and reduces the uniformity of atomization of the heat generating body 22. In this way, in the case where the distance D is 10 μm to 100 μm, not only the heat-generating body 22 is made easy, but also the uniformity of atomization of the heat-generating body 22 can be improved.

The distance D between two adjacent slits 223 is the distance between the width centers of the two adjacent slits 223 or the distance between the corresponding edges of the two adjacent slits 223.

Referring to fig. 7 and 9, in some embodiments, the ends of the plurality of slits 223 are disposed flush along the width direction of the slits 223. In this way, the plurality of slits 223 are regularly arranged, so that the atomized liquid flowing to the surface of the heating film 222 is more uniform, which is beneficial to improving the uniformity of atomization of the heating element 22, and further reducing the possibility of dry heating of the heating element 22. Of course, in other embodiments, the ends of the plurality of slits 223 may be disposed unevenly along the width direction of the slits 223.

Referring to fig. 10, in some embodiments, the slits 223 are arranged in a plurality of columns along a first direction x of the heating body 22, and each column of slits 223 includes a plurality of slits 223 arranged at intervals along a second direction y of the heating body 22, the first direction x being perpendicular to the second direction y.

Thus, the slits 223 are arranged in a multi-row and multi-column mode, the situation that the length of a single slit 223 is too long to be difficult to process can be avoided, the consistency of each slit 223 can be improved, the liquid discharging capacity of each position of the heating body 22 is basically the same, the resistance of the heating film 222 can be adjusted, the current path is optimized, the heating film 222 heats more uniformly, and the atomization uniformity of the heating body 22 can be improved. As in the example of fig. 10, the slit 223 arrangement may be arranged in 12 columns, and the number of rows formed by the slit 223 arrangement is greater than the number of columns.

Referring to fig. 10 and 11, in some embodiments, in two adjacent rows of slits 223, the slits 223 in one row of slits 223 are offset from the slits 223 in the other row of slits 223 along the first direction x. In this way, the probability of the end portions of the slits 223 penetrating each other can be reduced, and the production yield of the heating element 22 can be improved. In addition, the atomized substrate supplied to the surface of the heating film 222 can be distributed more uniformly by this arrangement, which is advantageous in improving the uniformity of atomization of the heating element 22.

Referring to fig. 10 and 11, in some embodiments, the end of the slit 223 is semicircular, and in two adjacent rows of slits 223, the center of the end of one slit 223 in one row of slits 223 and the center of the end of two adjacent slits 223 in the other row of slits 223 enclose an equilateral triangle. In this way, the distances between the adjacent slits 223 are approximately equal, and the atomized substrates are uniformly distributed on the surface of the heating film 222, so that the uniformity of atomization of the heating body 22 can be improved, and the probability of dry heating at a certain position of the heating film 222 can be reduced.

Referring to fig. 12 and 13, in some embodiments, the heat-generating body 22 includes a middle portion 226 and an edge portion 227 connected to the middle portion 226, the middle portion 226 is provided with a slit 223, the edge portion 227 is provided with a through hole 228, and the cross-sectional circumference of the through hole 228 is smaller than the cross-sectional circumference of the slit 223. In this way, the middle portion 226 is provided with the slit 223, and the edge portion 227 is provided with the through hole 228, so that more atomized substrate can pass through the middle portion 226 and be atomized, thereby improving the uniformity of atomization of the heat-generating body 22 and reducing the probability of dry heating of the heat-generating body 22.

Specifically, the number of slits 223 in the middle portion 226 may be plural, and specific features of the slits 223 are referred to the specific description of the above embodiments, and are not repeated herein. The through hole 228 may be a circular hole. The number of the through holes 228 is plural, and the through holes 228 may be regularly distributed or irregularly distributed. The size of the through hole 228 may be specifically set according to the requirement, so long as the through hole 228 can not only smoothly drain under the condition that a negative pressure is formed on one side of the heating film 222, but also lock under the condition that the air pressure on one side of the heating film 222 is normal.

In some embodiments, the thickness of the heater 22 ranges from 0.4mm to 1mm. In the case where the thickness of the heat-generating body 22 is less than 0.4mm, insufficient strength of the heat-generating body 22 and insufficient depth of the slit 223 may be caused, so that the heat-generating body 22 is insufficient in liquid locking ability to cause a liquid leakage or other adverse phenomenon; in the case where the thickness of the heat-generating body 22 is greater than 1mm, the depth of the slit 223 may be too deep to cause the atomized substrate to smoothly pass through the heat-generating body 22 to be atomized, and too thick of the heat-generating body 22 is also disadvantageous in the manufacturing process of the slit 223. Therefore, in the case where the thickness of the heat generating body 22 is in the above size range, the heat generating body 22 is made to have good liquid-guiding and liquid-locking properties and to be easy to manufacture.

Referring again to fig. 3 and 4, in some embodiments, the atomizing device 100 may further include a first seal 30, a base 40, a second seal 50, and a post 60, the first seal 30 sealing a gap between the mounting seat 21 and a sidewall of the reservoir chamber 11. The base 40 is inserted in the housing 10, and the second seal 50 seals the gap between the base 40 and the side wall of the liquid storage chamber 11. The pole 60 is mounted on the base 40 and contacts the heating film 222 of the heating body 22, and the pole 60 can transfer the power of the main unit 200 to the heating body 22 to heat the heating body 22.

Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more of the described features.
