[0030] First embodiment

[0031] Figure 1aA longitudinal cross-sectional view of the atomizing element of the first embodiment disclosed in the present invention; Figure 1b A cross-sectional view of the atomizing element at AA according to the first embodiment disclosed in the present invention; Figure 1c It is a schematic longitudinal section view of an aerosol bomb 800 with an atomizing element according to the first embodiment disclosed in the present invention.

[0032] like Figures 1a to 1c As shown, the atomizer element according to the first embodiment of the present invention includes an atomizer core 930, a liquid guiding element 200 and an atomizer element shell 929, wherein the liquid guiding element 200 covers the outer peripheral wall of the atomizer core 930, the inner peripheral wall of the atomizer element shell 929 covers the outer peripheral wall of the liquid guiding element 200, and the atomizer element shell 929 has a top opening 9291, a bottom opening 9292 and an internal cavity surrounded by the atomizer element shell 929, and the internal cavity includes the area of ​​the atomizer core 930 to form an atomization chamber 934.

[0033] One or more air guide channels 836 connected to the atomization chamber 934 are provided between the outer wall of the liquid guide element 200 and the inner wall of the atomization element shell 929. One or more liquid guide holes 837 are provided on the wall of the atomization element shell 929, and at least one liquid guide hole 837 is connected to at least one air guide channel 836.

[0034] The atomizer core 930 is preferably a tubular atomizer core 930, such as a tubular body such as a square tube or a round tube. The liquid guide element 200 is adapted to the atomizer core 930 and is also preferably designed to be tubular. The liquid guide element 200 may partially or completely cover the outer peripheral wall of the atomizer core 930. The atomizer element housing 929 is preferably made of metal or plastic, and one or more liquid guide holes 837 are provided on the wall portion of the atomizer element housing 929. The liquid guide hole 837 may be provided axially on the wall portion of the atomizer element housing 929, or may be provided radially on the wall portion of the atomizer element housing 929. In the present embodiment, it is preferred that several elongated liquid guide holes 837 are provided radially on the atomizer element housing 929, and at least one liquid guide hole 837 is connected to at least one air guide channel 836.

[0035] The outer wall of the tubular liquid guiding element 200 contacts the liquid introduced from the liquid guiding hole 837 at the position of the liquid guiding hole 837 , and the inner wall of the liquid guiding element 200 contacts the outer wall of the atomizer core 930 , thereby the liquid guiding element 200 conducts liquid to the atomizer core 930 .

[0036] A groove B may be provided on the inner circumferential wall of the atomizing element housing 929, or a groove A may be provided on the outer circumferential wall of the liquid guiding element 200, so as to form an air guiding channel 836 between the liquid guiding element 200 and the atomizing element housing 929, or a separately formed air guiding tube may be provided between the inner circumferential wall of the atomizing element housing 929 and the outer circumferential wall of the liquid guiding element 200 as the air guiding channel 836. According to the application requirements of the atomizing element, the maximum inscribed circle diameter of the cross section of the air guiding channel 836 is set to 0.05mm to 0.5mm, such as 0.05mm, 0.08mm, 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm. In applications with a small amount of atomization or a small viscosity of the liquid, the maximum inscribed circle diameter of the cross section of the air guiding channel 836 should be set smaller. On the contrary, the maximum inscribed circle diameter of the cross section of the air guiding channel 836 should be set larger.

[0037] The thickness of the liquid-conducting element 200 refers to the shortest distance that the liquid is conducted from one side of the liquid-conducting element 200 to the other side. The thickness of the tubular liquid-conducting element 200 is the thickness of the tube wall. The thickness of the liquid-conducting element 200 is 0.3 mm to 2 mm, such as 0.3 mm, 0.5 mm, 0.8 mm, 1.0 mm, 1.5 mm, 2 mm. A liquid-conducting element 200 with a smaller thickness can be better suited for atomizing elements with a narrow space, but when the thickness of the liquid-conducting element 200 is less than 0.3 mm, it is difficult to make a uniform liquid-conducting element 200. A liquid-conducting element 200 with a larger thickness has better strength and is more convenient to assemble, but when the thickness of the liquid-conducting element 200 is greater than 2 mm, it is usually difficult to install in a small atomizing element.

[0038] The density of the liquid conducting element 200 is 0.08 g / cm 3 Up to 0.35 g / cm 3 , such as 0.08 g / cm 3 , 0.1 g / cm 3 , 0.15 g / cm 3 , 0.2 g / cm 3 , 0.25 g / cm 3 , 0.3 g / cm 3 , 0.35 g / cm 3 , preferably 0.1 to 0.3 g / cm 3 When the density is less than 0.08 g / cm 3 When the density is greater than 0.35 g / cm, the liquid-conducting element 200 is not strong enough and is easily deformed or even wrinkled during assembly, which affects the stability of atomization. 3 When the liquid guiding speed is slow, the atomization efficiency is affected, and the hardness of the high-density liquid guiding element 200 is too high, the radial elasticity is insufficient, and the matching performance of the liquid guiding element 200 in the atomization element is reduced.

[0039] The liquid-conducting element 200 is formed into a three-dimensional network structure by thermal bonding of bicomponent fibers with a skin-core structure. The skin layer and the core layer of the bicomponent fiber can be a concentric structure or an eccentric structure. The bicomponent fiber can be a filament or a staple fiber, and the filament can be elasticized. The liquid-conducting element 200 made of filaments has greater rigidity, and the liquid-conducting element 200 made of staple fibers has better elasticity. Bicomponent fibers can be selected according to the performance requirements of the liquid-conducting element 200 to make a suitable liquid-conducting element 200. The core layer of the bicomponent fiber has a melting point that is more than 20°C higher than the skin layer, so that the core layer can maintain a certain rigidity when the fibers are thermally bonded, which is convenient for making a liquid-conducting element 200 with uniform gaps.

[0040] The cortex of the bicomponent fiber can be polyolefin, polyester, low melting point copolyester, or polyamide, such as polyethylene, polypropylene, copolyester of ethylene terephthalate (Co-PET), polypropylene terephthalate (PTT for short), polybutylene terephthalate (PBT for short), polylactic acid, polyamide-6, etc. When the cortex is polyethylene, the core layer can be a polymer such as polypropylene and polyethylene terephthalate (PET for short). When the cortex is polypropylene, the core layer can be PET, polyamide, etc. The cortex melting point of the bicomponent fiber is relatively low, which is beneficial to improve production efficiency and reduce manufacturing costs. The cortex melting point of the bicomponent fiber is relatively high, and the liquid-conducting element 200 has a higher temperature resistance, which is beneficial to increase the operating temperature of the atomizing core 930. The fineness of the bicomponent fiber for making the liquid-conducting element 200 of the present invention is between 1-30 deniers, preferably 1.5-10 deniers. The bicomponent fiber used in this embodiment has a fineness of 3 deniers, a skin layer of polyethylene, and a core layer of polypropylene. The liquid-conducting element 200 has a thickness of 0.6-1.2 mm and a density of 0.1-0.3 g / cm 3 .

[0041] The tubular atomizer core 930 is a porous material with a pre-embedded heating material, such as a porous ceramic with a pre-embedded heating wire, and the liquid can penetrate into the porous material. The cross-section of the atomizer core 930 can be circular, elliptical or other geometric shapes. A portion of the outer wall of the tubular liquid-conducting element 200 is introduced into the liquid to be atomized through the liquid-conducting hole 837. The liquid penetrates axially and radially in the liquid-conducting element 200 and is conducted to the atomizer core 930 through the liquid-conducting element 200. The atomizer core 930 may include a wire 933, which may be connected to an external wire pin 936.

[0042] like Figure 1cAs shown, the aerosol bomb 800 according to the present invention is equipped with the above-mentioned atomizing element. The aerosol bomb 800 also includes a liquid storage element 100 and an aerosol channel 1303 connected to the top opening 9291 of the atomizing element. The aerosol channel 1303 can be seamlessly docked on the top opening 9291 of the aerosol element as shown in the figure, or it can be connected to the top opening 9291 through a connecting mechanism or a clamping mechanism (not shown). The liquid storage element 100 can be integrally formed with the aerosol channel 1303, or they can be assembled together after being formed separately.

[0043] The liquid storage element 100 is a component for storing liquid in the aerosol bomb 800, and the liquid to be atomized is injected into the liquid storage element 100, such as electronic cigarette oil, air freshener, etc. The liquid storage element 100 can be a cavity made of plastic or metal.

[0044] Liquid is injected into the liquid storage element 100 of the aerosol bomb 800. The liquid reaches equilibrium after penetrating the liquid guide element 200 and the atomization core 930, and forms a certain negative pressure in the liquid storage element 100. Due to the capillary force, the air guide channel 836 is sealed by liquid.

[0045] The aerosol bomb 800 also includes a bottom sealing portion 112 of a liquid storage element housing disposed at the bottom of the aerosol bomb 800. A sealing portion through hole 1122 axially penetrating the bottom sealing portion 112 of the liquid storage element housing is formed on the bottom sealing portion 112 of the liquid storage element housing. The sealing portion through hole 1122 is communicated with the atomization chamber 934 and has a sealing portion air inlet 1121. When in use, the atomization core 930 is heated while the airflow enters the atomization chamber 934 through the sealing portion air inlet 1121. The liquid on the atomization core 930 is atomized and escapes from the aerosol channel 1303. The liquid guide element 200 replenishes the liquid to the atomization core 930 and absorbs the liquid from the liquid storage element 100 at the same time. As atomization proceeds, the negative pressure in the liquid storage element 100 increases, and the gas in the atomization chamber 934 enters the liquid storage element 100 through the gas guide channel 836 and the liquid guide hole 837 connected thereto until the gas-liquid exchange system is rebalanced. The liquid guide element 200 and the gas guide channel 836 thus form a stable gas-liquid exchange system in the atomization element, thereby achieving a smooth atomization process.

The atomizing element housing 929 is made of stainless steel, and two liquid guiding holes 837 are arranged radially opposite to each other at positions close to the bottom of the atomizing element housing 929 but at different heights from the bottom, and the arc length of each liquid guiding hole 837 is slightly longer than half of the circumference of the atomizing element housing 929, so that each air guiding channel 836 is connected to the liquid guiding hole 837.

The aerosol bomb 800 of this embodiment also includes a liquid-absorbing element 401 installed at the bottom of the aerosol bomb 800 to absorb liquid, thereby improving the leak-proof performance of the aerosol bomb 800. The liquid-absorbing element 401 can be installed below the bottom sealing portion 112 of the liquid storage element housing of the aerosol bomb 800, or two liquid storage element housing bottom sealing portions 112 can be set at the bottom of the aerosol bomb 800, and the liquid-absorbing element 401 is set between the two liquid storage element housing bottom sealing portions 112.
