The atomizer of the present invention comprises a mesh heating element that is wrapped around the outer or inner peripheral surface of the atomizer wicking element in a 360-degree surrounding manner, so that the atomizer has better strength and shape stability. The heat generated by the 360-degree surrounding mesh heating element can be evenly distributed on the surface of the atomizer wicking element, by which the liquid on the atomizer wicking element can be atomized more sufficiently, thereby making the atomization more stable and reliable, and the taste more delicate and fuller. The traditional atomizer with spiral heating elements and pins has poor shape stability, difficulty in controlling pin alignment during installation, and low assembly efficiency. Because the mesh heating element is wrapped around the outer or inner peripheral surface of the atomizer wicking element in 360-degree surrounding manner, the atomizer in the present invention does not need pins, so that the electrode can contact the outer or inner peripheral wall of the mesh heating element from any direction, which is conducive to the efficient assembly of the atomizer in the aerosol cartridge.
The atomizer in the prior art usually requires individual production, resulting in low production efficiency. According to the atomizer of the present invention, it is possible to continuously produce and harvest coiled atomizer material, which can greatly improve production efficiency and facilitate the storage and transportation of atomizer, thus significantly reduce the cost of atomizer. The atomizer can be installed by unwinding and cutting the required length, which is conducive to the automatic assembly of the atomizer.
Compared with the prior art, the atomizer of the present invention has low cost, good atomization sufficiency, delicate and full taste. The atomization of the aerosol cartridge using this atomizer is stable and reliable with small individual differences and good user experience.

The liquid supply port 825 is correspondingly arranged with the atomizing module liquid guide hole 712. The aerosol channel assembly port 826 has a downward extending tubular protrusion.

In this embodiment, the upper end of the atomizing module liquid guide hole is docked to the liquid supply port 825, and the lower end is in contact with the atomizer 930, thereby allowing the atomizer 930 to directly connect with the liquid in the liquid storage element 100.
The top outlet of the aerosol channel 1303 is an aerosol outlet 1301, and the bottom opening of the aerosol channel 1303 is the atomizing module connection port 1302, which is used to connect with the atomizing module upper interface 711.

As shown in
In this embodiment, since the mesh heating element 931 is wrapped around the outer peripheral surface of the atomizer wicking element 932 in a 360-degree surrounding manner, the pin connected from the atomizer 930 to the electrode 936 can be omitted. The electrode 936 can be electrically connected by contacting the mesh heating element 931 in any direction, thus reducing the difficulty of assembling the atomizer 930 in the aerosol cartridge 800 and greatly improving assembly efficiency.
The atomizer 930 of the present invention can continuously produce and harvest coiled atomizer material, which can greatly improve production efficiency and facilitate the storage and transportation of atomizer 930, thus significantly reducing the cost of atomizer 930.
When installing the atomizer 930, it can be unwound and cut the required length, which is conducive to the automatic assembly of the atomizer.
In this embodiment, the cross-section of the atomizer 930 can be made circular, but it can also be made elliptical or other geometric shapes as needed.
As shown in
In this embodiment, the mesh heating element 931 is adhered to the inner peripheral surface of the atomizer wicking element 932 in a 360-degree surrounding manner.
Preferably, the mesh heating element 931 includes two to eight resistance wires 9311, one part of which is left-handed resistance wires 9311a, and the other part is right-handed resistance wires 9311b.
As shown in
The atomizing module 700 according to this embodiment comprises an electrode 936 and an electrode insertion portion 9365 arranged at one end of the electrode 936, and the electrode insertion portion 9365 is connected to the mesh heating element 931 after inserted into the atomizer wicking element through-hole 932b. Specifically, the electrode insertion portion 9365 is in the shape of an earplug with a through hole, and the electrode insertion portions 9365 of the two electrodes 936 are respectively inserted into the atomizer wicking element through-hole 932b from the two ends of the horizontally arranged atomizer 930 and are connected to the mesh heating element 931.
In this embodiment, the liquid storage element sealing element 823 can be omitted, and the atomizing module upper cover 710 can also be used as the liquid storage element sealing element 823. The atomizing module upper cover 710 can be provided with only one atomizing module wicking hole 712. In order to transport the liquid in the liquid storage element 100 to the atomizer wicking element 932, the upper opening of the atomizing module wicking hole 712 is directly connected with the liquid in the liquid storage element 100, and its lower opening is in contact with the outer peripheral surface of the atomizer wicking element 932.
In this embodiment, aerosol cartridge 800 also comprises an aerosol channel 1303, and the angle between the atomizer wicking element through-hole 932b and the aerosol channel 1303 is greater than or equal to 45 degrees and less than or equal to 135 degrees when the atomizer wicking element 932 has an atomizer wicking element through-hole 932b that axially penetrates through the atomizer wicking element 932. Preferably, the angle between the atomizer wicking element through-hole 932b and the aerosol channel 1303 is 45 degrees, 60 degrees, 75 degrees, 90 degrees, 105 degrees, 120 degrees, and 135 degrees. The most preferred angle is basically equal to 90 degrees, that is to say, the most preferred configuration is that the atomizer wicking element through-hole 932b is arranged basically perpendicular to the aerosol channel 1303.
The atomizer wicking element through-hole 932b is connected with the aerosol channel 1303. When the aerosol cartridge 800 is working, the mesh heating element 931 surrounding the inner peripheral surface of the atomizer wicking element 932 evaporates the liquid, and the evaporated gas is mixed with the air flowing through the interior of the atomizer 930 to form an aerosol, which escapes through the aerosol channel 1303. This structure is conducive to the rapid replenishment of liquid from the liquid storage element 100 to the atomizer wicking element 932.
Moreover, because the atomizer wicking element through-hole 932b is arranged basically perpendicular to the aerosol channel 1303, the condensate of large particles is difficult to enter the aerosol channel 1303 due to inertia when the high-temperature condensate generated near the atomizer 930 turns vertically and enters the aerosol channel 1303, thereby reducing or avoiding the direct entry of condensate of large particles into the oral cavity and improving the user experience.

When the atomizing module 700 and the liquid storage element 100 are assembled together, an aerosol cartridge 800 can be formed.

In this embodiment, the gas-liquid exchange element 290 mainly plays the role of an independent breath guide without undertaking the function of transporting liquid to the atomizer wicking element 932.

It should be further explained that the mesh heating element 931 in the present invention forms a hollow columnar shape, and the hollow columnar mesh heating element 931 is wrapped around the outer peripheral surface of the atomizer wicking element 932 or is adhered to the inner peripheral surface of the atomizer wicking element 932.
In the present invention, the mesh number of the mesh heating element 931 is defined as the number of woven or etched mesh holes in the axial length of 25.4 millimeters of the mesh heating element 931. Mesh number is a measure of the density of woven or etched mesh holes.
In the present invention, the axial length of the mesh heating element 931 and the axial length of the atomizer wicking element 932 are basically equal, which means that the length difference between the two does not exceed 20%.
The mesh heating element 931 can include an electrified portion and a non-electrified portion. The electrified portion generates heat, which is also conducted to the non-electrified portion.
In the present invention, the wire diameter of the resistance wire 9311 refers to the diameter when the cross-section of the resistance wire 9311 is circular, but the cross-section of the resistance wire 9311 used in the present invention can be any geometric shape, which can be converted into the diameter of a circular resistance wire 9311 with the same cross-sectional area as the wire diameter of the resistance wire 9311 when the cross-section of the resistance wire 9311 is non-circular.
In the present invention, the resistance of atomizer 930 refers to the resistance measured by the two electrodes 936 after the atomizer 930 is connected to the electrodes 936.
The parts that are the same as other embodiments in this embodiment will not be repeated.
As shown in
The atomizer wicking element 932 is used to transport the liquid to be atomized to the atomizer 930, and its material can include fibers or powders containing cellulose, carbon fibers, glass fibers, ceramic fibers, porous ceramics, etc. The most commonly used atomizer wicking element 932 includes cotton rope or glass fiber. The weight of the atomizer wicking element 932 per meter is preferably 1.0 to 6.0 grams, and more preferably 1.8 to 4.5 grams. Cotton rope has good taste reductibility for atomized liquids, and glass fiber and porous ceramics are heat-resistant and have advantages in systems that require high-temperature atomization, such as THC atomization.
In the present invention, resistance wire 9311 generally refers to metal or non-metal wires that have a certain resistance and can generate heat when energized, such as nickel-chromium alloy wire, iron-chromium alloy wire, etc. The cross-section of resistance wire 9311 can be geometric shapes such as circular or rectangular, of which the circular is the most commonly used. The preferred wire diameter for resistance wire 9311 is 10 to 150 microns, such as 10, 12.5, 20, 25, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120, 150 microns, etc. The more preferred wire diameter for resistance wire 9311 is 25 to 100 microns.
As shown in
In the present invention, the resistance of the atomizer 930 refers to the resistance measured by two electrodes 936 after the atomizer 930 is connected to the electrodes 936. In the present invention, the resistance of the atomizer 930 is preferably 0.2 ohms to 2.0 ohms, such as 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1.0, 1.2, 1.5, 1.8, 2.0 ohms, etc. The normal resistance of the atomizer 930 entwined with spiral resistance wire 9311 is 1.2 to 1.8 ohms. Since the mesh heating element 931 can flexibly select the wire diameter, quantity and mesh number of the resistance wire 9311, the range of resistance can be greatly expanded to meet different application needs. For example, 8 to 36 resistance wires 9311 can be used to weave a two-layer mesh heating element 931, so that the resistance of the atomizer 930 is as low as 0.2 to 1.0 ohms, and the lower resistance of the atomizer 930 can extend the battery's lifespan when the host is outputting constant power.
Preferably, the mesh heating element 931 includes 4 to 36 resistance wires 9311, and more preferably the number of resistance wires 9311 is a multiple of 4 or 6 among the 4 to 36 wires, such as 4, 6, 8, 12, 16, 18, 20, 24, 28, 32, 36, etc.
Preferably, the number of mesh holes is 20 to 300 in 25.4 millimeters of the axial length of the mesh heating element, that is, the mesh number of the mesh heating element 931 ranges from 20 to 300, such as 20 mesh, 30 mesh, 40 mesh, 50 mesh, 60 mesh, 70 mesh, 80 mesh, 100 mesh, 120 mesh, 150 mesh, 200 mesh, 250 mesh, 300 mesh, etc. In the case that the number of resistance wires 9311 is the same, the smaller mesh number is beneficial for the atomizer 930 to produce larger aerosol particles, resulting in moister aerosol taste; a larger mesh number is beneficial for the atomizer 930 to produce fine aerosol particles, and the aerosol taste is relatively dryer.
As shown in
As shown in
In the present invention, the left-handed and right-handed resistance wire 9311 can be used in various ways such as one up and one down, one up and two down, or two up and two down when the resistance wire 9311 is woven or cross-wound.
As shown in
As shown in
As shown in
As shown in
According to the first and the second aerosol cartridge of the fifth embodiment of the present invention, the atomizer wicking element 932 is made of cotton rope weighing 3.2 grams per meter, and the resistance wire 9311 used to make the mesh heating element 931 has a wire diameter of 60 microns.
The output power of each aerosol cartridge for the best suction taste is as follows, which is obtained by injecting three different aerosol liquids, such as tobacco flavor, mint tobacco flavor, and double apple hookah flavor into the aerosol cartridge, and comparing and testing with an adjustable constant power output host.
The experimental results show that the atomizer 930 with a two-layer mesh heating element 931 can achieve the best suction taste at lower power by comparing with the atomizer 930 with a single-layer mesh heating element 931, including aroma stimulation, fullness, persistence, aerosol temperature, etc., so the atomizer 930 with a two-layer mesh heating element 931 is conducive to saving the power of the host and increasing the endurance. The experimental results also show that the atomizer 930 with a two-layer mesh heating element 931 can produce more delicate mist and richer aroma than the atomizer 930 with a single-layer mesh heating element 931. These results indicate that the liquid is atomized by the first layer mesh heating element 931 closely attached to the atomizer wicking element 932 in the aerosol cartridge with a two-layer mesh heating element 931, and then further heated or baked by the mesh heating elements 931 of other layers, which is beneficial for reducing the particles of the aerosol, and making the atomization more complete, thereby allowing the user to feel a more delicate, drier, and more fragrant aerosol.
In this embodiment, the first electrode 936a with an electrode clampingpiece 9364 clamps the atomizer 930, and the upper end of the second electrode 936b is in contact with the lower end of the first electrode 936a. The advantage of this split type of electrode 936 is that it can improve the flexibility of connecting the aerosol cartridge 800 to the host (not shown in the figures).
The atomizer 930 of the present invention is conducive to making the mesh heating element 931 into a structure of two or more layers (including two layers), wherein the first layer of mesh heating element 931 in contact with the atomizer wicking element 932 heats and atomizes the liquid, and the generated aerosol is further heated and baked by other layers of mesh heating elements 931, resulting in more delicate and drier smoke and more sufficient aroma stimulation. The traditional atomizer with spiral heating elements and pins has poor shape stability, difficulty in controlling pin alignment during installation, and low assembly efficiency. Because the mesh heating element 931 is wrapped around the outer or inner peripheral surface of the atomizer wicking element in 360-degree surrounding manner, the atomizer 930 of the present invention has high strength and good stability without pins, so that the electrode can contact the outer or inner peripheral wall of the mesh heating element from any direction, which is conducive to the efficient assembly of the atomizer in the aerosol cartridge.
The mesh heating element 931 according to this embodiment can also be formed by interlocking at least two polygonal-shape resistance wires 9311 at adjacent bends. As shown in
The hollow columnar mesh heating element 931 is wrapped around the outer peripheral surface of the atomizer wicking element 932 or adhered to the inner peripheral surface of the atomizer wicking element 932, so that the atomizer 930 has good strength and shape stability, the heat generated by the 360-degree surrounding mesh heating element 931 can be evenly distributed on the surface of the atomizer wicking element 932, and the liquid on the atomizer wicking element 932 can be atomized more evenly, thereby making the atomization more stable and reliable, and making the taste more delicate and full.
The manufacturing method of the tenth atomizer provided by the present invention comprises the following steps:
As shown in
The mesh heating element 931 is preferably adhered to the inner peripheral surface of the atomizer wicking element 932 in a 360-degree surrounding manner.
The atomizer 930 also comprises electrodes 936, which are parallel to axial direction of the mesh heating element 931 and are connected to the mesh heating element 931. Electrodes 936 are preferably wires.
In this embodiment, the mesh heating element 931 can be one layer, or two or more layers (including two layers). The electrode 936 and the mesh heating element 931 can be connected by welding or mechanical contact.
When the mesh heating element 931 has two or more layers, the electrode 936 can be buried between the mesh heating elements 931 of the first layer and the second layer, so that the electrode 936 is in contact with the mesh heating element 931.
Preferably, the electrode 936 consists of two wires axially parallel to the mesh heating element 931. To make the atomizer evenly heated, the circumference of the cross-section of the mesh heating element 931 is divided equally by the two wires.
The length of the connection between the electrode 936 and the mesh heating element 931 can be equal to or less than the axial length of the mesh heating element 931.
In this embodiment, the resistance of the atomizer 930 can be changed by changing the length of the connection between the electrode 936 and the mesh heating element 931.
In this embodiment, the atomizer wicking element 932 can be made of non-woven fabric, cotton paddle, etc. At least a part of the outer peripheral surface of the atomizer wicking element 932 is sleeved with a hollow metal tube 9396 and a hollow metal tube wall through-hole 9397 is arranged on the tube wall of the hollow metal tube 9396, the outer face of the atomizer wicking element 932 is connected with the liquid in the liquid storage element 100 through the hollow metal tube wall through-hole 9397.
In this embodiment, the atomizer 930 is arranged parallel or coincident with the central axis of the aerosol channel 1303, the hollow metal tube 9396 is connected with the aerosol channel 1303 after the atomizer 930 is inserted into the liquid storage element 100, the hollow metal tube wall through-hole 9397 is in direct contact with the liquid in the liquid storage element 100, and the liquid in the liquid storage element 100 is conducted to the atomizer wicking element 932 through the hollow metal tube wall through-hole 9397.
In this embodiment, as shown in
As shown in
In this embodiment, the mesh heating element 931 is adhered to the inner peripheral surface of the atomizer wicking element 932 in a 360-degree surrounding manner.
Preferably, the mesh heating element 931 includes 8-36 resistance wires 9311, one part of which is a left-handed resistance wire 9311a, and the other part is a right-handed resistance wire 9311b.
As shown in
The atomizing module 700 according to this embodiment comprises an electrode 936 and an electrode clampingpiece 9364 arranged at one end of the electrode 936, and the electrode clampingpiece 9364 clamps a mesh heating element 931.
When the mesh heating element 931 is adhered to the inner peripheral surface of the atomizer wicking element 932 in a 360-degree surrounding manner, an atomizer wicking element cutout 932e penetrating through the peripheral wall of the atomizer wicking element 932 can be provided on the atomizer wicking element 932. Thus, the electrode 936 can pass through the atomizer wicking element cutout 932e and clamps the outer peripheral surface of the mesh heating element 931 radially from the atomizer 930.
In this embodiment, the liquid storage element sealing element 823 can be omitted, and the atomizing module upper cover 710 can also be used as the liquid storage element sealing element 823. The atomizing module upper cover 710 can be provided with a first atomizing module wicking hole 712a and a second atomizing module wicking hole 712b. In order to transport the liquid in the liquid storage element 100 to the atomizer wicking element 932, the upper opening of the first atomizing module wicking hole 712 is directly connected with the liquid in the liquid storage element 100, and its lower opening is in contact with the outer peripheral surface of the atomizer wicking element 932.
In this embodiment, aerosol cartridge 800 also comprises an aerosol channel 1303, and the angle between the atomizer wicking element through-hole 932b and the aerosol channel 1303 is greater than or equal to 45 degrees and less than or equal to 135 degrees when the atomizer wicking element 932 has an atomizer wicking element through-hole 932b that axially penetrates through the atomizer wicking element 932. Preferably, the angle between the atomizer wicking element through-hole 932b and the aerosol channel 1303 is 45 degrees, 60 degrees, 75 degrees, 90 degrees, 105 degrees, 120 degrees, and 135 degrees, and the most preferred angle is basically equal to 90 degrees, that is to say, the most preferred configuration is that the atomizer wicking element through-hole 932b is arranged basically perpendicular to the aerosol channel 1303.
The atomizer wicking element through-hole 932b is connected with the aerosol channel 1303. The mesh heating element 931 surrounding the inner peripheral surface of the atomizer wicking element 932 evaporates the liquid when the aerosol cartridge 800 is working, and the evaporated gas is mixed with the air flowing through the interior of the atomizer 930 to form an aerosol, which escapes through the aerosol channel 1303. This structure is conducive to the rapid replenishment of liquid from the liquid storage element 100 to the atomizer wicking element 932.
The upper opening of the second atomizing module wicking hole 712b is directly connected with the liquid in the liquid storage element 100, and its lower opening is connected with the atmosphere. The second atomizing module wicking hole 712b is provided with a gas-liquid exchange element 290, and the gas-liquid exchange element 290 can be a tubular bonded fiber or tubular plastic product or tubular metal product including axial through-holes. In this embodiment, the gas-liquid exchange element 290 is mainly used for delivering gas to the liquid storage element 100, thereby making the atomization of the atomizing module 700 more stable and reliable. A buffer chamber can be set up around the lower part of the gas-liquid exchange element, and the gas-liquid exchange element can also suck back the liquid leaked into the buffer chamber in case of abnormal conditions to the storage element.
The embodiment shown in
When the electrode clampingpiece 9364 of the electrode 936 is designed as two, one electrode 936 can clamp two atomizer 930 simultaneously. For example, the electrode clampingpiece 9364 of the electrode 936 can be designed in a W shape or a double U shape. The electrode 936 can be punched out with a metal sheet to form a W-shaped or double U-shaped electrode clampingpiece 9364.
Because one electrode 936 can clamp two atomizer 930 simultaneously, the manufacturing difficulty of atomizing module 700 with more than two atomizer 930 and aerosol cartridge 800 can be significantly reduced, the manufacturing efficiency is greatly improved and the cost is reduced. This structure can exponentially increase the amount of aerosol, making it suitable for atomizing devices 1 that require a large amount of atmospheric aerosol, such as electronic water cigarettes.
In summary, the atomizer 930 of the present invention includes a mesh heating element 931 that is wrapped around the outer peripheral surface of the atomizer wicking element 932 in a 360-degree surrounding manner, and/or is adhered to the inner peripheral surface of the atomizer wicking element 932 in a 360-degree surrounding manner. The atomizer 930 has good strength and shape stability.
The heat generated by the 360-degree surrounding mesh heating element 931 can be more evenly distributed on the surface of the atomizer wicking element 932, and the liquid on the atomizer wicking element 932 can be heated more efficiently, so that the atomization is more sufficient, and the user can obtain more delicate and full taste.
The atomizer of the present invention is conducive to making the mesh heating element 931 into a structure of two or more layers (including two layers). Compared to a single-layer mesh heating element 931, the use of an aerosol cartridge with two or more layers (including two layers) of mesh heating element 931 results in more complete atomization and more delicate aerosol.
According to the atomizer 930 of the present invention, because the mesh heating element 931 is wrapped around the outer peripheral surface of the atomizer wicking element 932 in a 360-degree surrounding manner, and/or is adhered to the inner peripheral surface of the atomizer wicking element 932 in a 360-degree surrounding manner, the atomizer 930 does not need to be provided with pins connected with the electrode 936, so that the electrode 936 can contact the outer or inner peripheral wall of the mesh heating element 931 from any direction, which is conducive to the assembly of the atomizer 930 in the aerosol cartridge 800.
According to the atomizer 930 of the present invention, it is possible to continuously produce and harvest coiled atomizer material, which can greatly improve production efficiency and facilitate the storage and transportation of atomizer 930, thus significantly reducing the cost of atomizer 930. When installing the atomizer 930, the coiled atomizer material can be unwound and cut the required length, which is conducive to the automatic assembly of the atomizer.
