Abstract
Description
Technical Field
[0001] This application relates to the field of atomization technology, and in particular to providing an atomizer and an electronic atomization device. Background Technology
[0002] Electronic atomizing devices mainly consist of an atomizer and a power supply. The atomizer typically includes a liquid reservoir, a coil, an air outlet, absorbent cotton, and a mouthpiece. The liquid reservoir stores the liquid aerosol matrix; the coil heats and atomizes the liquid aerosol matrix to form an edible aerosol. The absorbent cotton is located at the junction of the air outlet and the mouthpiece, and it absorbs the condensate produced during atomization.
[0003] Current absorbent pads are typically made from fibers in sheets, rolls, or tubes, and then punched and cut. The absorbent pads have a uniform overall density, resulting in a slow and gradual diffusion of liquid during absorption, leading to a low absorption rate and poor liquid transfer. Furthermore, some existing absorbent pads, due to different manufacturing processes, have longitudinally distributed fibers, resulting in poor horizontal liquid transfer, affecting the absorption rate, and making it prone to condensation leakage at the suction nozzle. Utility Model Content
[0004] The purpose of this application is to provide a liquid-absorbing cotton, an atomizer, and an electronic atomizing device, in order to solve the problems of low liquid absorption rate and poor diffusion and transfer effect of liquid on the existing liquid-absorbing cotton.
[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:
[0006] In a first aspect, embodiments of this application provide an absorbent cotton, which has a layered structure and includes an innermost first cotton body and a second cotton body disposed outside the first cotton body; the first cotton body has through holes, and the density of the first cotton body is less than the density of the second cotton body.
[0007] The beneficial effect of the absorbent cotton of this application is that, since the density of each layer of the absorbent cotton increases sequentially from the inside to the outside, after the first cotton body absorbs a certain amount of liquid, the liquid absorbed by the first cotton body will be actively and continuously transferred to the second cotton body under the drive of density difference and fiber capillary action. The liquid can quickly diffuse from the inside to the outside of the absorbent cotton to each layer. The diffusion and transfer effect of the liquid on the absorbent cotton is good, which effectively improves the liquid absorption rate.
[0008] By adopting the above technical solution, the absorbent cotton with an inner and outer double-layer structure is formed by combining the first cotton body and the second cotton body. When the amount of liquid absorbed by the first cotton body reaches a certain level, the liquid will be actively transferred to the second cotton body under the drive of density difference and capillary action.
[0009] In one possible design, the second cotton body is provided with a receiving groove for accommodating the first cotton body, the peripheral shape of the receiving groove being configured to match the outer peripheral shape of the first cotton body; the first cotton body is embedded in the receiving groove.
[0010] By adopting the above technical solution, the first cotton body and the second cotton body are separate structures. The first cotton body is embedded into the receiving groove on the second cotton body so that the two are combined to form absorbent cotton. The structure is simple and convenient to assemble manually, which saves product manufacturing costs.
[0011] In one possible design, the receiving groove is configured to have an interference fit with the first cotton body.
[0012] By adopting the above technical solution, the first cotton body is interference-fitted into the receiving tank, which improves the contact effect between the first cotton body and the second cotton body and facilitates liquid transfer.
[0013] In one possible design, the outer periphery of the first cotton body is connected to the inner periphery of the second cotton body in the receiving groove.
[0014] By adopting the above technical solution, the fibers of the first cotton body and the fibers of the second cotton body are further connected, so that the capillary action between the fibers of the first cotton body and the second cotton body is better and the liquid transfer effect is better.
[0015] In one possible design, the fibers of the first cotton body are distributed horizontally; the fibers of the second cotton body are distributed horizontally.
[0016] By adopting the above technical solution, the fibers of the first cotton body and the second cotton body are distributed in a horizontal direction, that is, a horizontal continuous "microporous channel" is formed in both the first cotton body and the second cotton body, which is conducive to the rapid transfer of liquid on the horizontal plane. In other words, the liquid can be rapidly transferred from the center of the absorbent cotton to the surrounding area, effectively improving the oil absorption rate of the absorbent cotton and effectively improving the performance of the absorbent cotton.
[0017] In one possible design, the thickness range of the first cotton body is configured as 0.5mm-5mm; and / or, the thickness range of the second cotton body is 0.5mm-5mm.
[0018] By adopting the above technical solution, the thickness of the first cotton body and the second cotton body is within a suitable range, ensuring the diffusion range of liquid on the absorbent cotton.
[0019] In one possible design, the thickness of the second cotton body is configured to be greater than or equal to the thickness of the first cotton body.
[0020] By adopting the above technical solution, the thickness of the second cotton body is greater than that of the first cotton body, which allows the liquid to be transferred better from the first cotton body to the second cotton body, thereby improving the diffusion effect of the liquid on the absorbent cotton.
[0021] In one possible design, the liquid-absorbing cotton further includes at least one third cotton body covering the outside of the second cotton body, and the third cotton bodies are arranged in a nested manner; the density of any third cotton body is greater than the density of the second cotton body, and the density of each third cotton body increases from the inside to the outside of the liquid-absorbing cotton.
[0022] By adopting the above technical solution, the absorbent cotton is not limited to a two-layer structure. A third cotton body can be set outside the second cotton body to form a three- or four-layer structure.
[0023] Secondly, embodiments of this application provide an atomizer, including a main body, an atomizing core disposed within the main body, and a liquid-absorbing cotton; the main body includes a mouthpiece portion, and a connecting airway connecting the atomizing core and the mouthpiece portion and a liquid storage chamber for storing an aerosol matrix are formed within the main body, the liquid storage chamber being used to supply liquid to the atomizing core; the liquid-absorbing cotton is horizontally disposed at the junction of the connecting airway and the mouthpiece portion.
[0024] The beneficial effects of the atomizer of this application are as follows: by using the absorbent cotton of this application, the liquid can be rapidly transferred and diffused from the center of the absorbent cotton to the surrounding area. The absorbent cotton has a good oil absorption rate and oil absorption volume, which effectively reduces the risk of liquid leakage from the atomizer.
[0025] Thirdly, embodiments of this application provide an electronic atomizing device, including a power supply assembly and the atomizer; the power supply assembly is used to supply power to the atomizing core of the atomizer. Attached Figure Description

[0044] Electronic atomizing devices mainly consist of an atomizer and a power supply. The atomizer generally includes a liquid reservoir, a coil, an air outlet, absorbent cotton, and a mouthpiece. The liquid reservoir stores the liquid aerosol matrix; the coil heats and atomizes the liquid aerosol matrix to form an edible aerosol. The absorbent cotton is located at the junction of the air outlet and the mouthpiece, absorbing condensate produced during atomization. Current absorbent cotton is often made of fiber-formed sheets, rolls, or tubes, which are then stamped and cut. The absorbent cotton has a uniform overall density, resulting in a slow, even diffusion of the liquid during absorption, leading to a low absorption rate and poor liquid transfer. Furthermore, some existing absorbent cottons, due to different manufacturing processes, have longitudinally distributed fibers, resulting in poor horizontal liquid transfer, affecting the absorption rate, and easily causing condensate leakage at the mouthpiece.
[0045] Based on this, in order to solve the above problems, this application designs a liquid-absorbing cotton. By setting the density of each layer of the liquid-absorbing cotton to increase sequentially from the inside out, that is, after the innermost layer absorbs a certain amount of liquid, the liquid absorbed by the innermost layer will be actively and continuously transferred to the outer layers under the drive of density difference and fiber capillary action. The liquid can quickly diffuse from the inside to the outside of the liquid-absorbing cotton to each layer. The diffusion and transfer effect of the liquid on the liquid-absorbing cotton is good, which effectively improves the liquid absorption rate. Subsequently, when the liquid-absorbing cotton is applied to the atomizer, the liquid absorption performance of the liquid-absorbing cotton is good, which effectively reduces the risk of liquid leakage of the atomizer.
[0046] refer to Figure 1 This application provides an electronic atomizing device 2000, including a power supply assembly 3000 and an atomizer 1000. The power supply assembly 3000 supplies power to the atomizer 1000. The power supply assembly includes a battery 3001 for supplying power to the atomizer 1000. The battery is electrically connected to the atomizer 1000 through internal wiring and / or a pin connector or other electrical connection methods.
[0047] Specifically, the power supply assembly 3000 also includes a suction sensing assembly, which includes a microphone. The suction sensing assembly is used to detect and sense changes in the suction airflow to determine whether to activate the atomizer 1000.
[0048] refer to Figure 1 , Figure 2 In some embodiments, the atomizer 1000 includes a main body 2, an atomizing core 3 disposed within the main body 2, and a liquid-absorbing cotton 1; the main body 2 includes a mouthpiece 4, and a connecting airway 5 connecting the atomizing core 3 and the mouthpiece 4 and a liquid storage chamber 6 for storing aerosol matrix are formed within the main body 2, the liquid storage chamber 6 being used to supply liquid to the atomizing core 3; the liquid-absorbing cotton 1 is horizontally disposed at the junction of the connecting airway 5 and the mouthpiece 4.
[0049] Specifically, the atomizing core 3 is used to heat and atomize the aerosol matrix stored in the liquid storage tank 6 to generate an aerosol that can be inhaled by the user. The aerosol enters the mouthpiece 4 through the connecting airway 5. The mouthpiece 4 has a mouthpiece channel 401, and the absorbent cotton 1 is located between the connecting airway 5 and the mouthpiece channel 401. Understandably, during the process of the aerosol flowing from the connecting airway 5 into the mouthpiece channel 401, there is a phenomenon of aerosol condensation to form condensate. If the condensate is not absorbed in time, it may cause leakage at the mouthpiece 4, affecting the user experience. Therefore, the absorbent cotton 1 is provided to absorb the condensate in time to reduce the risk of leakage.
[0050] refer to Figure 2 , Figure 3 , Figure 5 , Figure 6 In some embodiments, the absorbent cotton 1 of this application has a layered structure and includes an innermost first cotton body 101 and a second cotton body 102 disposed outside the first cotton body 101; the first cotton body 101 has through holes 7, and the density of the first cotton body 101 is less than the density of the second cotton body 102.
[0051] Specifically, during the atomization process, the innermost first cotton body 101 of the atomizer 1000 first contacts the condensate at the inner periphery of the through hole 7 and absorbs the condensate. After the innermost first cotton body 101 absorbs a certain amount of liquid, the liquid is transferred and diffused from the innermost first cotton body 101 to the outer second cotton body 102.
[0052] Understandably, the absorbent cotton 1 includes, but is not limited to, the first cotton body 101 and the second cotton body 102. That is, the absorbent cotton 1 may further have cotton bodies outside the second cotton body 102 to form a ring 11; the absorbent cotton 1 may include two or more rings 11. The aerosol matrix is e-liquid, and each ring 11 may include one or more of the following oil-absorbing materials: oil-absorbing cotton, oil-absorbing felt, oil-absorbing paper film, sponge, etc., which have a good oil-absorbing effect.
[0053] In some embodiments, each layer 11 of the absorbent cotton 1 is made of oil-absorbing cotton, and each layer 11 may include an oil-absorbing cotton body of one material, so that the density distribution of the individual layer 11 is more uniform and a density difference can be effectively formed between the individual layers 11; or, a single layer 11 may also be composed of oil-absorbing cotton bodies of multiple materials connected together, without specific limitation.
[0054] refer to Figure 3 , Figure 4 The first cotton body 101 and the second cotton body 102 can be a separate structure, that is, the first cotton body 101 and the second cotton body 102 are formed separately and then nested together to form the absorbent cotton 1. Alternatively, the first cotton body 101 and the second cotton body 102 can be a one-piece molded structure.
[0055] In the absorbent cotton 1 of this application, since the density of each layer 11 increases sequentially from the inside to the outside, after the innermost first cotton body 101 absorbs a certain amount of liquid, the liquid absorbed by the innermost first cotton body 101 will be actively and continuously transferred to the outer second cotton body 102 under the drive of density difference and fiber capillary action. The liquid can quickly diffuse from the inside to the outside of the absorbent cotton 1 to the interlayer layer 11. The diffusion and transfer effect of the liquid on the absorbent cotton 1 is good, which effectively improves the liquid absorption rate.
[0056] refer to Figures 2-6 In some embodiments, the absorbent cotton 1 has only two layers 11; that is, the absorbent cotton 1 is formed by combining a first cotton body 101 and a second cotton body 102 to form an inner and outer double-layer structure, and the density of the first cotton body 101 is less than the density of the second cotton body 102, forming a density difference between them, and the fiber distribution of the second cotton body 102 is denser than that of the first cotton body 101. During the atomization process of the atomizer 1000, the first cotton body 101 first contacts the condensate at the inner periphery of the through hole 7 and absorbs the condensate. After the first cotton body 101 absorbs a certain amount of liquid, the liquid absorbed by the first cotton body 101 will be actively and continuously transferred to the surrounding second cotton body 102 under the drive of density difference and fiber capillary action.
[0057] Understandably, both the first cotton body 101 and the second cotton body 102 possess oil-locking and oil-storage capabilities. Oil-locking capability refers to the ability to lock in liquid and prevent leakage. Oil-storage capability refers to the ability to store and contain atomized liquid. For the same volume, the higher the density of the cotton body and the denser its fibers, the more contact the liquid has with the fibers, resulting in stronger adsorption (capillary) between the liquid and the fibers, making it easier for the liquid to be locked in the cotton body. Conversely, the lower the density of the cotton body and the sparser its fibers, the more voids there are in the microstructure of the same volume of cotton body, allowing more liquid to be stored. Therefore, compared to the same volume of the first cotton body 101 (inner layer) and the second cotton body 102 (outer layer), the first cotton body 101 has a stronger oil-storage capability because its density is lower than that of the second cotton body 102. This means the first cotton body 101 comes into contact with the condensate first and can quickly absorb a larger amount of liquid in a short time. The second cotton body 102 has a stronger oil-locking ability, so after the liquid is transferred from the first cotton body 101 to the second cotton body 102, it is less likely to drip. That is, the absorbent cotton 1 of this application, by combining the first cotton body 101 and the second cotton body 102, can significantly improve the liquid absorption rate and oil absorption volume, and reduce the risk of leakage of the atomizer 1000.
[0058] refer to Figure 3 , Figure 4 In some embodiments, the second cotton body 102 is provided with a receiving groove 8 for receiving the first cotton body 101, and the peripheral shape of the receiving groove 8 is configured to match the outer peripheral shape of the first cotton body 101; the first cotton body 101 is embedded in the receiving groove 8.
[0059] Understandably, a receiving groove 8 is provided at the center of the second cotton body 102, and the first cotton body 101 can be embedded in the receiving groove 8; the receiving groove 8 is specifically a hollow groove.
[0060] refer to Figures 4-6 Both the first cotton body 101 and the second cotton body 102 are separate cotton body structures, that is, they are separate structures. After the first cotton body 101 and the second cotton body 102 are made separately, the first cotton body 101 is embedded into the receiving groove 8 on the second cotton body 102 so that the two are combined to form the absorbent cotton 1. The structure is simple and convenient to assemble manually, which saves product manufacturing costs.
[0061] Specifically, the outer periphery shape of the first cotton body 101 can be set to any shape such as circle, ellipse, or polygon, without any specific limitation; the periphery shape of the receiving groove 8 is configured to match the outer periphery shape of the first cotton body 101. The outer periphery shape of the second cotton body 102 can also be set to any shape such as circle, ellipse, or polygon, as long as the first cotton body 101 can be embedded in the second cotton body 102.
[0062] In some embodiments, the receiving groove 8 is configured to have an interference fit with the first cotton body 101.
[0063] Understandably, the first cotton body 101 is interference-fitted into the receiving groove 8, so that the first fiber of the first cotton body 101 and the second fiber of the second cotton body 102 are in close contact, which is more conducive to the transfer of liquid from the first cotton body 101 to the second cotton body 102 under capillary action, thereby improving the liquid absorption and diffusion capacity of the absorbent cotton 1.
[0064] refer to Figure 3 , Figure 5 , Figure 6 In some embodiments, the outer periphery of the first cotton body 101 is connected to the inner periphery of the second cotton body 102 in the receiving groove 8.
[0065] After the first cotton body 101 is embedded in the receiving groove 8 of the second cotton body 102, the fibers at the outer periphery of the first cotton body 101 are further connected to the fibers at the inner periphery of the second cotton body 102 in the receiving groove 8.
[0066] Specifically, after the first cotton body 101 is embedded in the second cotton body 102, the fibers of the first cotton body 101 and the fibers of the second cotton body 102 are intertwined or bonded together by one or more of the following methods: needle punching, hydroentangling, thermal bonding, and chemical bonding. This ensures that the fibers of the first cotton body 101 and the second cotton body 102 are interconnected, improving structural stability and effectively preventing the first cotton body 101 from detaching from the receiving groove of the second cotton body 102.
[0067] Understandably, the fibers at the outer periphery of the first cotton body 101 and the fibers at the inner periphery of the second cotton body 102 in the receiving groove 8 form a connection relationship, which makes the capillary action between the fibers of the first cotton body 101 and the second cotton body 102 better and the liquid transfer effect better.
[0068] In some embodiments, the fibers of the first cotton body 101 are distributed in a horizontal direction; the fibers of the second cotton body 102 are distributed in a horizontal direction.
[0069] Understandably, refer to Figure 2 The absorbent cotton 1 is horizontally placed inside the atomizer 1000. After the absorbent cotton 1 absorbs the liquid at the through hole 7, the liquid diffuses and transfers outward in the horizontal direction. If the transfer effect of the liquid on the absorbent cotton 1 on the horizontal plane is not good, it will affect the liquid absorption rate and the phenomenon of condensate leakage at the nozzle 4 is likely to occur. Therefore, it is important to improve the horizontal diffusion ability of the liquid on the absorbent cotton 1.
[0070] Specifically, both the first cotton body 101 and the second cotton body 101 are manufactured using a fiber web-laying process. This process involves mechanically interlacing or bonding fibers together to form a uniform nonwoven web. The nonwoven web is then reinforced and shaped using one or more of the following processes: needle punching, hydroentangling, thermal bonding, and chemical bonding. This results in a nonwoven fabric with a robust structure and good dimensional stability and elasticity. The web-laying process ensures that the fibers in both the first and second cotton bodies 101 are horizontally distributed. This allows for the formation of continuous horizontal "microporous channels" between the fibers within both the first and second cotton bodies 101, increasing the oil conductivity of the absorbent cotton 1 and facilitating rapid liquid transfer on a horizontal surface, thus enhancing the horizontal diffusion of the liquid on the absorbent cotton 1.
[0071] In some embodiments, the density range of the first cotton body 101 is configured as 50–200 kg / m³. 3 Specifically, the density of the first cotton boll 101 can be set to 50 kg / m³. 3 70kg / m 3 75kg / m 3 100kg / m 3 125kg / m 3 150kg / m 3 175kg / m 3 200kg / m 3 Any one of them.
[0072] The density range of the second cotton boll 102 is configured as: 150~200kg / m³ 3 Specifically, the density of the second cotton boll 102 can be set to 150 kg / m³. 3 160kg / m 3 170kg / m 3 180kg / m 3 190kg / m 3 200kg / m 3 Either of them. The density of the second cotton body 102 is greater than that of the first cotton body 101, forming a density difference between them. The liquid absorbed by the first cotton body 101 will be actively and continuously transferred to the surrounding second cotton body 102 under the drive of the density difference and fiber capillary action. This facilitates the rapid diffusion and transfer of liquid from the center of the absorbent cotton 1 to the surrounding areas, improving the liquid absorption rate and resulting in better liquid absorption.
[0073] In some embodiments, the thickness of the first cotton body 101 is configured to be in the range of 0.5-5 mm, with reference to... Figure 3The thickness direction of the first cotton body 101 is consistent with the extension direction of the through hole 7; specifically, the thickness of the first cotton body 101 can be set to any one of 0.5mm, 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, and 5mm. The thickness range of the second cotton body 102 is configured as 0.5-5mm, specifically, the thickness of the second cotton body 102 can be set to any one of 0.5mm, 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, and 5mm.
[0074] refer to Figure 3 The first cotton body 101 is embedded in the second cotton body 102. Preferably, the thickness of the second cotton body 102 is greater than or equal to the thickness of the first cotton body 101. In other words, the second cotton body 102 completely covers the first cotton body 101, and the liquid absorbed by the first cotton body 101 can be transferred to the surrounding second cotton body 102, thereby improving the diffusion effect of the liquid on the absorbent cotton.
[0075] In some embodiments, the liquid-absorbing cotton 1 further includes at least one third cotton body (not shown) covering the outside of the second cotton body 102, and the third cotton bodies are arranged in a nested manner; the density of any third cotton body is greater than the density of the second cotton body 102, and the density of each third cotton body increases from the inside to the outside in the liquid-absorbing cotton 1.
[0076] Understandably, the absorbent cotton 1 may also have a structure of three or more layers, including at least one third cotton body that is fitted outside the second cotton body 102.
[0077] For example, the absorbent cotton 1 may include a third cotton body, that is, the absorbent cotton 1 has a three-layer structure; or, the absorbent cotton 1 may also include two third cotton bodies, which are nested layer by layer outside the second cotton body 102, so that the absorbent cotton 1 has a four-layer structure.
[0078] Specifically, when the absorbent cotton 1 has a structure of three or more layers, the absorbent cotton 1 as a whole still satisfies the requirement that the density of each layer is distributed in a gradient, that is, in the direction from the inside to the outside of the absorbent cotton 1, the density of each layer 11 of the absorbent cotton 1 shows an increasing trend.
[0079] In some embodiments, the fibers used in the first cotton body 101 and the second cotton body 101 are one or more mixtures of natural fibers, renewable fibers, and synthetic fibers; wherein, the natural fibers are one or more mixtures of cotton fibers, hemp fibers, coconut fiber, wood pulp fibers, bamboo fibers, wool fibers, and silk fibers. The renewable fibers are one or more mixtures of viscose fibers, lyocell fibers, and cupro fibers. The synthetic fibers are polyethylene terephthalate (PET), polyethylene (PE), polypropylene (PP), etc.
[0080] In some embodiments, this application also provides the liquid absorption and diffusion effect of the absorbent cotton 1 formed by the combination of the first cotton body 101 and the second cotton body 102 under the scheme of this application; and the liquid absorption and diffusion effect of the absorbent cotton with a single-layer cotton body structure in the prior art.
[0081] The specific test procedure is as follows: Place the absorbent cotton 1 flat on the table, use a pipette to draw 50 μL of aerosol matrix, and slowly drip it along the inner wall of the through hole 7 of the first cotton body 101. After 30 seconds, measure the diffusion length of the aerosol matrix on the absorbent cotton 1.
[0082] The basic parameters for all tests are consistent.
[0083] In this application, the first cotton body 101 is uniformly a circular structure with an inner diameter of 3.5 mm and an outer diameter of 5.5 mm; the second cotton body is uniformly a rectangular structure with an inner diameter of 5.5 mm, a length of 10 mm, and a width of 8 mm. Both the first cotton body 101 and the second cotton body 102 are made of PET fiber (polyester fiber).
[0084] When the absorbent cotton is a single-layer cotton structure, it is uniformly a rectangular structure with an inner diameter of 3.5mm, a length of 10mm, and a width of 8mm; and the absorbent cotton is made of PET fiber (polyester fiber).
[0085] The aerosol matrix used is e-liquid with a PG (Propylene Glycol):VG (Vegetable Glycerin) ratio of 5:5.
[0086] Test data for each absorbent cotton 1 under the technical solution of this application:
[0087]
[0088] Table 1
[0089] Test data for absorbent cotton with a single-layer cotton structure:
[0090]
[0091] Table 2
[0092] By comparing data 1, data 2, and data 3 in Table 1 with data 1, data 2, and data 3 in Table 2, we can see that:
[0093] Compared with the single-layer cotton structure, the gradient density design of the absorbent cotton 1 formed by the combination of the first cotton body 101 and the second cotton body 102 in this application undoubtedly has a longer liquid absorption diffusion length, that is, the oil absorption rate and diffusion transfer ability of the absorbent cotton 1 are better, and the liquid absorption capacity is stronger. Therefore, when the absorbent cotton 1 provided by this application is applied in an atomizer, it can effectively reduce the risk of leakage.
[0094] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
