Detailed Description

In order to facilitate understanding of the present invention, the present invention will be described more fully hereinafter with reference to the accompanying drawings. The preferred embodiments of the present invention are shown in the drawings. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "inner", "outer", "left", "right" and the like as used herein are for illustrative purposes only and do not represent the only embodiments.

Referring to fig. 1, one embodiment of the present invention provides an atomization assembly 10 for atomizing a liquid, represented by an aerosol-generating substrate, to form an aerosol for inhalation by a user, the atomization assembly 10 including a substrate 100, an electrode film 200, and a heat-generating film 300.

In some embodiments, the substrate 100 comprises a porous ceramic substrate, i.e., the substrate 100 may be made of a porous ceramic material. For example, firstly, providing a mixed raw material of porous ceramics, such as alumina, zirconia, silicon carbide and the like, then adding a certain proportion of adhesive, stabilizer, paraffin and the like into the mixed raw material according to requirements, mixing and extruding to form a blank, then degreasing and sintering the extruded blank, and finally combining the blank under the action of high temperature to form a finished porous ceramic matrix. The porous ceramic matrix has good chemical stability, the melting point is above 1000 ℃, namely the porous ceramic matrix can resist high temperature, and the porous ceramic matrix can not produce chemical reaction with liquid under a high-temperature environment, so that extra loss of the liquid in the chemical reaction process is avoided, and the liquid is ensured to be completely used for atomization, thereby improving the utilization rate of the liquid.

The matrix 100 made of porous ceramic material contains a large number of micropores therein and has a certain porosity, which is defined as the percentage of the volume of the pores in the object to the total volume of the material in a natural state. The porosity of the substrate 100 may be 50% to 60%, for example, the porosity may be 50%, 55%, 58%, or 60%. The cross-sectional dimension of the micro-pores is 1 μm to 100 μm, for example, the cross-sectional dimension of the micro-pores can be 1 μm, 10 μm, 50 μm or 100 μm, and when the micro-pores are circular holes, the cross-sectional dimension of the micro-pores is the diameter of the micro-pores. Because the base body 100 has a certain porosity, the base body 100 can form a capillary action, the base body 100 has the atomizing surface 100, under the capillary action, liquid in contact with the base body 100 can be continuously transmitted to the atomizing surface 100 through the inside of the base body 100, and when the heat generating film 300 works, heat generated by the heat generating film 300 can atomize the liquid on the atomizing surface 100 to form smoke.

When the porosity and the cross-sectional size of the micropores are increased, the on-way resistance of the liquid moving in the matrix 100 can be reduced, and then the liquid guiding speed of the matrix 100 to the liquid is increased, so that the liquid permeating in the matrix 100 can be transmitted to the atomization surface 100 in a shorter time, and the phenomena of liquid drop explosion and scorching caused by insufficient liquid on the atomization surface 100 are avoided. When the porosity and the cross-sectional size of the micropores are both reduced, the base body 100 can have a relatively stronger liquid locking function for liquid permeating into the base body, the liquid stored in the base body 100 is prevented from leaking from the atomizing surface 100, and the base body 100 is ensured to have a good liquid storage effect. Therefore, in order to balance the liquid guiding speed and the liquid locking function of the substrate 100, the values of the porosity and the cross-sectional size of the micropores may be set within the above ranges, respectively. Of course, the extension direction of the micro-holes may be perpendicular to the atomization surface 100, so that the liquid can reach the atomization surface 100 through the shortest distance, and the liquid guiding speed of the substrate 100 to the liquid is further increased.

Referring to fig. 1 to 5, the base 100 may have a cylindrical or prismatic shape, the side circumference of the base 100 forms the atomizing surface 100, the base 100 has two end surfaces 120 connected to the atomizing surface 100, and the two end surfaces 120 of the base 100 may be used for contacting with the liquid to adsorb the liquid. The base body 100 may further include a liquid guiding hole 130 for allowing liquid to pass through, the liquid guiding hole 130 may penetrate through the two end faces 120 of the base body 100 to form a through hole, a cross-sectional dimension of the liquid guiding hole 130 is 0.5mm to 1.5mm, for example, a value of the cross-sectional dimension of the liquid guiding hole 130 may be 0.5mm, 0.6mm, 0.8mm, or 1.5mm, and when the liquid guiding hole 130 is a circular hole, the cross-sectional dimension of the liquid guiding hole 130 is a diameter of the circular hole. Through setting up drain 130, because the cross sectional dimension of drain 130 is obviously greater than the cross sectional dimension of micropore for liquid can get into base member 100 inside through this drain 130 at a faster speed at first, and the liquid that is located drain 130 then reaches atomizing surface 100 through the micropore, also plays the effect of improving base member 100 drain speed like this further. The number of the liquid guide holes 130 can be one, and the central axis of the liquid guide holes 130 is coincident with the central axis of the base body 100, so that the conducting distances from the liquid in the liquid guide holes 130 to the atomizing surface 100 are approximately equal, and the liquid is ensured to be uniformly distributed on the atomizing surface 100. The number of the liquid guiding holes 130 can also be multiple, for example, the central axis of one liquid guiding hole 130 is coincident with the central axis of the base body 100, and the central axes of the other liquid guiding holes 130 are parallel to the central axis of the base body 100; for another example, when some of the fluid conducting holes 130 are annular holes, the central axes of all the fluid conducting holes 130 may coincide with the central axis of the substrate 100. In other embodiments, the base 100 may have a truncated cone shape, a truncated pyramid shape, or the like, as the actual situation requires.

in some embodiments, the heating film 300 includes a stainless steel heating film, a titanium heating film, or a titanium alloy heating film, i.e., the heating film 300 may be made of stainless steel, titanium metal, or titanium alloy, for example, stainless steel may be selected as S316L type stainless steel, etc., the heating film 300 made of the above materials has good temperature control characteristics, e.g., the heating temperature of the heating film 300 may be precisely controlled and adjusted, when the heating temperature increases, more liquid may be atomized in a unit time to form a higher mist concentration, and sufficient energy may exist to destroy the force between liquid molecules, so that the particle size of the mist is smaller, whereas, when the heating temperature decreases, the mist concentration decreases and the particle size increases, therefore, the size of the liquid atomizing particles and the atomizing concentration may be precisely controlled by adjusting the heating temperature of the heating film 300, so as to adjust the taste of the mist to meet the needs of different users, while the temperature of the heating film 300 may be prevented from being too high, so as to avoid generating harmful substances at high temperature, such as to adjust the heating area of the heating film 300 (which generates heat) to form a smaller amount of the mist, so that the heating film 300 may be capable of atomizing the liquid may generate heat when the mist generates heat, and thus the same amount of the liquid 300 may be adjusted.

The heating film 300 can be attached to the atomization surface 100 of the base 100 through a spraying process or an electroplating process, and the spraying process and the electroplating process are both convenient to operate through automation equipment, so that the processing efficiency and the processing precision are improved. When the heating film 300 works, the temperatures of all the parts on the heating area are equal, so that the heat can be uniformly distributed on the heating area, the phenomenon that the local temperature is too high on the heating area is avoided, the liquid drop explosion phenomenon caused by the too high local temperature is prevented, the liquid loss caused by the liquid drop explosion is reduced, the utilization rate of the liquid is further improved, and enough liquid is ensured to be atomized under the same condition to form higher smoke concentration.

In some embodiments, the electrode film 200 may also be attached to the atomization surface 100 of the substrate 100 through a spray coating process or a plating process, so that the spray coating process and the plating process are performed using automated equipment, thereby improving the processing efficiency and accuracy. The electrode film 200 is electrically connected to the heating film 300, and the electrode film 200 is connected to the power supply through the thimble 400, that is, the thimble 400 is disposed between the power supply and the electrode film 200, for example, the lower end of the thimble 400 is fixedly connected to the power supply, and the upper end of the thimble 400 can be abutted to or fixedly connected to the electrode film 200. The power supply may supply power to the heat generating film 300 through the thimble 400 and the electrode film 200 so that the heat generating film 300 generates an atomization temperature to atomize the liquid.

Compared with the conventional atomization assembly 10, because the long-strip-shaped pins are fixedly connected to the base 100, the pins need to be manually bent to form a reasonable bending angle in the whole manufacturing process of the atomization assembly 10; meanwhile, in the process of assembling the atomizing assembly 10 with other parts, the pins also need to be manually guided to prevent the pins from interfering with other parts, so that the pins are ensured to be smoothly connected with a power supply. In the above embodiment, the electrode film 200 is of a film structure, so that the electrode film 200 is conveniently directly attached to the base 100 by an automated device, and the electrode film 200 of the film structure occupies a small space, and the electrode film 200 does not protrude to an excessive length relative to the base 100 like a pin, so that the entire atomizing assembly 10 is compact in structure, eliminates interference in the assembly process, and is also convenient for assembly line assembly by the automated device. Also, the attachment of the heat generating film 300 may be performed by an automated apparatus, which itself occupies a small space without interference during the assembly process. Therefore, in the manufacturing and assembling process of the atomizing assembly 10, the electrode film 200 and the heat generating film 300 are arranged to eliminate the manual participation, so that the automation level of the manufacturing and assembling of the atomizing assembly 10 is improved, the efficiency and the precision of the manufacturing and assembling of the atomizing assembly 10 are finally improved, the mass production of the atomizing assembly 10 is realized, and the manufacturing cost is reduced.

Referring to fig. 1, 4 to 7, in some embodiments, the heating film 300 and the electrode film 200 are both ring-shaped, and the base 100 is disposed through the heating film 300 and the electrode film 200, so that the stability and reliability of the attachment of the heating film 300 and the electrode film 200 can be improved. When the base body 100 has a prismatic shape, the heat generating film 300 and the electrode film 200 have polygonal rings in cross section; when the base body 100 is cylindrical, the heat generating film 300 and the electrode film 200 are both circular rings in cross section. When the cross section of the heating film 300 is a polygonal ring, one or more surfaces of the heating film 300 can be controlled to form a heating area, so that the size of the heating area can be adjusted; when the cross section of the heating film 300 is a circular ring, the arc value corresponding to the heating area on the heating film 300 can be controlled to adjust the size of the heating area. Obviously, when the heating area is changed, the atomization amount and the smoke concentration of the atomization assembly 10 are changed. Of course, in the case where the volume of the base 100 is constant, the maximum atomization amount of the atomization assembly 10 may be determined by changing the total area size of the heat generation film 300.

Referring to fig. 1 to 4, in consideration of installation condition limitations or smoke concentration, both the heat generating film 300 and the electrode film 200 may not cover the entire atomization surface 100, that is, the total projected area of both the heat generating film 300 and the electrode film 200 on the atomization surface 100 is smaller than the area of the atomization surface 100. For example, the atomization surface 100 includes an installation region 112 and an exposed region 111, the exposed region 111 is located at two ends of the atomization surface 100, that is, there are two exposed regions 111, the installation region 112 is located in the middle of the atomization surface 100 and is sandwiched between the two exposed regions 111, and both the heating film 300 and the electrode film 200 are attached to the installation region 112, and obviously, the atomization surface 100 of the exposed region 111 is not attached with any heating film 300 or electrode film 200 and is in an exposed state. The atomizing surface 100 of the mounting region 112 may be recessed toward the central axis of the base body 100 by a set depth relative to the atomizing surface 100 of the exposed region 111 to form a groove 140, and the heat generating film 300 or the electrode film 200 is embedded in the groove 140, and when the thicknesses of the heat generating film 300 and the electrode film 200 are equal to the depth of the groove 140, the surface of the heat generating film 300 or the electrode film 200 may be flush with the atomizing surface 100 of the exposed region 111 at the same time. Of course, referring to fig. 5, the atomizing surface 100 of the mounting region 112 may be flush with the atomizing surface 100 of the exposed region 111, and when the heat generating film 300 and the electrode film 200 are attached to the mounting region 112, the heat generating film 300 and the electrode film 200 protrude a set height relative to the atomizing surface 100 of the exposed region 111.

The electrode film 200 includes a first electrode film 210 and a second electrode film 220, the first electrode film 210 is connected to a positive electrode of a power supply through one of the lift pins 400, the second electrode film 220 is connected to a negative electrode of the power supply through the other lift pin 400, and the heat generating film 300 is located between the first electrode film 210 and the second electrode film 220. At this time, the electrode film 200 is disposed closer to the exposed region 111 than the heating film 300, so that two ends of the heating film 300 are respectively abutted to the first electrode film 210 and the second electrode film 220, thereby achieving electrical connection between the heating film 300 and the electrode film 200, and thus omitting the arrangement of other connecting parts, thereby simplifying the overall structure of the atomizing assembly 10 and reducing the manufacturing cost thereof.

Referring to fig. 8 and 9, the present invention further provides an atomizer 20, wherein the atomizer 20 includes a thimble 400, a housing assembly 500, a base assembly 600 and the atomizing assembly 10. The base subassembly 600 sets up in the casing subassembly 500, base subassembly 600 encloses into a stock solution chamber 520 with the casing subassembly 500 jointly, the storage has the liquid that supplies atomizing subassembly 10 atomizing in the stock solution chamber 520, the base member 100 sets up on base subassembly 600, the tip of base member 100 is located stock solution chamber 520, can be so that the terminal surface 120 of base member 100 from the continuous absorption liquid in stock solution chamber 520, when having seted up drain hole 130 in the base member 100, the liquid in the stock solution chamber 520 can directly get into inside the base member 100 through drain hole 130. The shell assembly 500 is provided with an air suction channel 510 communicated with the outside, the base assembly 600 is provided with an atomization cavity 610 communicated with the air suction channel 510, the atomization cavity 610 is isolated from the liquid storage cavity 520, and the heating film 300 can be just positioned in the atomization cavity 610. When the heating film 300 is operated, the liquid on the atomizing surface 100 is atomized to form smoke, and the smoke passes through the atomizing chamber 610 and the air suction passage 510 to be sucked by a user. Because the electrode film 200 and the heating film 300 are attached to the base body 100, the atomization assembly 10 is compact in structure, interference generated by the atomization assembly 10 in the whole assembly process of the atomizer 20 is eliminated, assembly line assembly is facilitated through automatic equipment, and assembly efficiency and accuracy of the atomizer 20 are improved.
