Description

Atomizing core device

Technical Field

The utility model relates to the technical field of atomization, in particular to an atomization core device.

Background

The prior atomizing core is usually provided with a heating element made of ceramic materials. Because the ceramic material is resistant to high temperature and high pressure, and resistant to acid, alkali, organic medium corrosion and the like, the ceramic heating element has good biological inertia, so that the service life of the heating element made of the porous ceramic material is long. On the other hand, the controllable pore structure of the ceramic heating element can effectively improve the performance of the ceramic heating element in the aspect of oil storage, so that the heating element is manufactured by adopting porous ceramic materials in more atomization cores in the actual use process. The inventors have found the following problems in using existing atomizing cores:

firstly, pores in the ceramic heating body are used for realizing the functions of oil guiding and oil seepage, and the existing ceramic heating body has the problems of slow liquid guiding, unsmooth liquid guiding, small smoke quantity, poor taste reduction degree and the like. When the porosity of the existing ceramic heating element is 35-58%, and liquid flows into a gap from an opening on the surface of the ceramic heating element, the opening area is smaller than the surface of the ceramic heating element, so that when a large amount of liquid positioned on the outer side of the ceramic heating element needs to pass through a narrower opening, the rate of the liquid entering the pores is influenced, and the liquid guiding efficiency is influenced. Meanwhile, solid sediment is inevitably present in the atomized liquid, and when the solid sediment flows into the pores along with the liquid, the solid sediment easily blocks the pores on the ceramic heating element, so that the liquid guide is not smooth. In addition, because the ceramic heating body has certain rigidity, after the pore is blocked, a user can hardly take out and clean the precipitate from the pore.

And secondly, the ceramic heating element is formed by sintering common particles such as alumina, silicon, quartz stone, glass and the like, and dust and fine particles are easy to generate on the ceramic heating element in the atomization heating process. Dust, particles will be inhaled by the user with the smoke and there will be health risks in using an atomizing core made of ceramic heat generating bodies. On the other hand, the sintering temperature of the conventional ceramic heating element is 1500-2500 ℃. The ceramic heating element has more detection contents in the sintering manufacturing process, is complex to prepare and has high detection management and control risk. The prior method for controlling the temperature in the manufacturing process is limited, so that the phenomena of hole blocking, hole breaking or unsmooth hole can occur more easily in the sintering process, and the defective rate of the produced ceramic heating element is increased. Meanwhile, the ceramic heating element has high brittleness, and the ceramic heating element is damaged when the force applied during assembly is excessive in the assembly process, so that the ceramic heating element is easy to crack during use. Further increasing the reject ratio of the product.

Finally, the ceramic heating element is not uniform in temperature during heating, and heat is difficult to transfer to a place with low temperature, so that the highest temperature position is concentrated in the middle of the ceramic heating element. The temperature difference can lead to uneven atomization of liquid in the ceramic heating body, insufficient atomization of liquid in the peripheral pores of the ceramic heating body, and the phenomena of oil absorption, oil flying, oil climbing and the like are easy to occur, so that the user experience is affected when a user inhales.

Referring to fig. 1-4, fig. 1 is a schematic perspective view of an atomization core structure according to some embodiments of the present application, fig. 2 is a schematic perspective view of a liquid collecting and heating module according to some embodiments of the present application, fig. 3 is a bottom view of the atomization core structure according to some embodiments of the present application, and fig. 4 is a cross-sectional view at A-A in fig. 3. According to some embodiments of the present application, there is provided an atomizing core device comprising: housing 100, liquid collector 200, and heating module 300. The housing 100 is hollow to form a hollow portion 13. The liquid collector 200 is accommodated in the hollow portion 13. The liquid collector 200 is used for storing an atomizing liquid (hereinafter referred to as liquid), and the liquid in the liquid collector 200 flows downward by its own weight to approach the heating module 300 located at the bottom of the liquid collector 200.

In this embodiment, the liquid collecting body 200 includes at least two stacked liquid guiding layers, and the liquid guiding layers are provided with pores as the flow guiding channels of the liquid collecting body 200. Specifically, the liquid-guiding layer includes a top liquid-guiding layer 21 and a bottom liquid-guiding layer 22, the top liquid-guiding layer 21 is located at the top layer of the liquid-collecting body 200, and the bottom liquid-guiding layer 22 is located at the bottom layer of the liquid-collecting body 200. The heating module 300 includes a heating body 31, the heating body 31 is attached to the bottom liquid guiding layer 22, and the heating body 31 heats the liquid stored in the bottom liquid guiding layer 22. After the external liquid is guided into the liquid guiding layer, the liquid continuously flows downwards along with the pores, so that the liquid is continuously supplied to the bottom liquid guiding layer 22.

Meanwhile, the heating body 31 is attached to the bottom liquid guide layer 22, and an upward thrust exists on the heating body 31, so that the heating body 31 and the hollow part 13 squeeze the liquid guide layer in the liquid collecting body 200, and the liquid guide layer is elastically deformed to a certain extent. Specifically, when the heating body 31 applies a pressure of 1kgf or more to the liquid-guiding layers, the pressing force is applied to the liquid-guiding layers, so that the liquid can be smoothly caused to flow between the adjacent two liquid-guiding layers. After the liquid guide layer receives the extrusion force, the pores in the liquid guide layer are bent, the bent pores can not block the pores, and the pores of the liquid guide layer can be mutually overlapped to communicate the pores of the adjacent liquid guide layer, so that the seepage liquid guide can be finished smoothly.

Illustratively, the liquid-conducting layer is made of cotton-like material. Because cotton material's hydroscopicity is excellent to the water absorption speed of liquid-guiding layer is comparatively steady, so that multilayer liquid-guiding layer can stably permeate, and liquid adsorbs in the liquid-guiding layer, and liquid is difficult for breaking away from the liquid-guiding layer, avoids producing the phenomenon of flying liquid, and the phenomenon of flying liquid mainly appears as the user in the suction process liquid breaks away from the liquid collection body 200 and is inhaled along with the air current together. Meanwhile, the liquid guide layers are tightly attached, so that no gap exists between the liquid cotton layers, and liquid is prevented from being stored in the gap between the liquid cotton layers. If gaps exist between the liquid cotton layers, when a user inhales gas, the gas flow passes through the gaps, and liquid stored in the gaps is easily carried out. Therefore, the liquid guide layers are tightly attached by pressing, and the phenomenon of liquid flying can be effectively avoided.

Compared with the ceramic heating element: first, the liquid collector 200 made of cotton-based material is safer to use. The sintering materials of the existing ceramic heating bodies are often alumina, silicon, quartz stone, glass and the like. The ceramic heating element can be stripped of dust and fine particles in the heating and atomizing process, and the dust and fine particles are inhaled by a user along with the gas when the gas is inhaled, so that the human body is damaged. The liquid guiding layer in the scheme belongs to natural high molecular compounds, does not contain inorganic particles, and is not easy to fall off dust and particles during heating. The user is prevented from inhaling the solid of small particles, and the use safety is ensured.

Secondly, the liquid collector 200 made of cotton material has high atomization efficiency. In the atomization process, heat is easy to concentrate at local positions, so that the temperature at the local positions is higher than that at other positions, and the atomization efficiency at the positions with high temperature is high. And the permeation efficiency among the pores in the ceramic heating body is low, so that the phenomenon of local dry combustion can be more easily caused. For example, the temperature at the local position where heat is concentrated on the ceramic heat-generating body reaches 200 to 300 ℃, and at this time, the temperature at other positions on the ceramic heat-generating body is usually lower than 100 ℃, which makes the atomization efficiency non-uniform throughout the ceramic heat-generating body, and the problem of insufficient atomization easily occurs. Alternatively, in order to adequately atomize, it will result in the localized sites of heat build-up already beginning to dry out in the later stages of atomization, so that the gases inhaled by the user are doped with a burnt smell. In the scheme, due to the characteristics of the cotton materials, the pores in the liquid guide layer are staggered with each other, so that the liquid guide layer has better permeability. After the liquid at the position with higher temperature on the liquid guide layer is atomized, the liquid which is not atomized at the position with reduced atomization efficiency in the liquid guide layer can locally permeate towards the position with higher temperature on the liquid guide layer, so that the liquid at the position with higher temperature on the liquid guide layer is supplemented, and the phenomenon of dry combustion is avoided. Simultaneously, better permeability makes more liquid direction temperature higher department atomize to in order to improve this atomizing core device holistic atomization efficiency.

Finally, a liquid collector 200 made of cotton-based material requires lower manufacturing costs. The ceramic heating element is easy to generate defective products with the problems of hole blocking, hole breaking, unsmooth hole and the like in the sintering process. An important reason for producing such bad products is that the ceramic heating element manufacturing process requires more detection content, the preparation process is complex, the detection and control risk is high, the temperature required by sintering the ceramic heating element is in the range of 1500-2500 ℃, and the means for controlling the temperature required by sintering is limited at present, and the main relying way is through the detection means. The detection means can not improve the yield, only defective products can be screened out, and the higher defective products result in the increase of the raw material cost in the manufacturing process. On the other hand, the ceramic heating element has large brittleness and is extremely easy to crack when knocked, so that the ceramic heating element is fragile and easy to crack in the production and assembly process, and a large amount of ceramic heating elements are lost, so that the cost is increased. Compared with a ceramic heating body, the manufacturing process of the cotton material liquid guide layer is simpler, the flaky cotton can be cut into the required size by adopting die cutting, and the detection method can adopt a soaking weighing method and the like for measurement. The cotton material liquid guide layer is simple to process and prepare, and the required manufacturing cost is low.

It should be noted that the material of the liquid-guiding layer includes, but is not limited to, cotton-like materials. The material of the liquid-guiding layer can also be selected from non-woven fabrics and flax. The non-woven fabric and the flax material have excellent water absorption and permeability, and also have stronger compression resistance and tensile resistance. Therefore, the liquid guiding layer made of non-woven fabrics and flax can also smoothly realize liquid guiding and seepage. Or the liquid collecting body 200 can be formed by stacking a plurality of liquid guiding layers made of different materials such as cotton, non-woven fabrics and flax.

According to some embodiments of the present application, the housing 100 includes a housing 11, and the hollow portion 13 is provided inside the housing 11. The hollow portion 13 extends to the bottom surface 115 of the housing 11 so that an opening is formed on the bottom surface 115 of the housing 11. The liquid collector 200 protrudes from the opening into the hollow portion 13. In addition, the heating body 31 also extends into the hollow portion 13 from the opening, and applies a force to the heating body 31 toward the liquid collector 200, so that the heating body 31 is abutted against the bottom liquid guiding layer 22, and each liquid guiding layer is elastically deformed. The atomization core module is convenient to disassemble and assemble by arranging an opening. Because the liquid collecting body 200 and the heating body 31 can enter and exit the hollow part 13 from the opening, the liquid collecting body 200 and the heating body 31 can be replaced conveniently in the scheme.

In a preferred embodiment, as described in fig. 4, and with reference to fig. 7, fig. 7 is a cross-sectional view of a housing provided in some embodiments of the present application. The housing 100 further includes a compression plate 12, the compression plate 12 being connected to the housing 11. The pressing sheet 12 is located at the bottom of the heating body 31, and is connected with the shell 11 through the pressing sheet 12, so that the pressing sheet 12 applies a pushing force to the heating body 31 located in the hollow part 13, and then all the liquid guide layers are mutually extruded to form an integral structure of the liquid collector 200.

Further, the pressing piece 12 is connected to the hollow portion 13, and the hollow portion 13 is partitioned into a housing chamber 131 and a transition chamber 132 which are disposed in this order by the pressing piece 12. Wherein the transition chamber 132 is disposed proximate to and in communication with the opening. The housing chamber 131 is located above the transition chamber 132, and the liquid collector 200 and the heating body 31 provided in the hollow portion 13 are finally housed in the housing chamber 131.

Specifically, in order to deform the liquid collector 200 contained in the containing cavity 131, in this embodiment, referring to fig. 8, fig. 8 is a cross-sectional view of an atomizing core structure according to some embodiments of the present disclosure. Depth h of accommodating chamber 131 ₁ Less than the sum h of the thicknesses of the liquid collector 200 and the heating body 31 ₂ . Wherein, the depth h of the accommodating cavity 131 ₁ Is the distance between the surface of the tablet 12 and the top surface of the receiving cavity 131. Sum h of thicknesses of collector 200 and heating body 31 ₂ The total thickness of the liquid-guiding layers and the heating body 31 is set in a stacked manner before deformation. In order to load the liquid collector 200 and the heating body 31 into the accommodating cavity 131, the pressing sheet 12 and the accommodating cavity 131 apply force to the liquid collector 200 and the heating body 31, and the elastic liquid guide layers are deformed by extrusion to reduce the thickness of the liquid collector 200, so that the thicknesses of the liquid collector 200 and the heating body 31 are matched with the depth of the accommodating cavity 131. And the liquid guiding layers pressed against each other will bend or the parts of the adjacent liquid guiding layers overlap (the pores are mutually filled).

The heating module 300 further includes a lead wire 32, one end of the lead wire 32 is connected to the heating body 31, and the other end thereof is connectable to a power source. Specifically, the number of the leads 32 is two, and the two leads 32 are respectively connected to the positive and negative electrodes, so that the heating body 31 normally performs the atomizing operation. The pads 12 are provided with relief holes so that the leads 32 extend out of the housing 100 through the relief holes to conduct power. In this embodiment, a through hole is formed in the middle position of the pressing sheet 12, so that the pressing sheet 12 has a ring-shaped pressing plate 122 structure. While the hole in the middle of the pressing plate 122 serves as the air hole 121 and the relief hole. Since the pressing sheet 12 is supported at the bottom of the heating body 31, the atomization efficiency of the liquid is higher as the liquid approaches the heating body 31, that is, the amount of smoke generated on the bottom liquid guiding layer 22 is the full, and the atomized gas can overflow from the atomization core device through the air holes 121.

Preferably, the heating body 31 is made of one of iron chromium, nickel chromium and the like, the heating body 31 made of iron chromium or nickel chromium has stronger corrosion resistance and heat resistance, so that the heating range of the heating body 31 is within the range of 500-2000 ℃, the service life of the heating body 31 can be effectively prolonged, the heating body 31 can be in a silk-screen shape or a sheet shape, the shape of the heating body 31 is consistent with the shape of the liquid guide layer, the heating body 31 heats all positions of the liquid guide layer, the thickness of the heating body 31 is 0.08-0.3mm, and the resistance is 0.5-2.8Ω.

The heating body 31 is formed with a gap hole 311, and the atomizing gas can flow outward from the gap hole 311.

Further, as shown in fig. 7, the pressing piece 12 is detachably connected to the housing 11, and the pressing piece 12 is detachable from the housing 11, so as to facilitate the removal of the liquid collector 200 and the heating body 31 from the receiving chamber 131. Illustratively, the press sheet 12 is detachably connected with the housing 11 through a buckle 111, the buckle 111 is circumferentially arranged on the inner wall of the hollow part 13, and the press sheet 12 extends into the hollow part 13 from the opening and is connected with the buckle 111. Specifically, a mounting plane is formed around the circumferentially arranged fastener 111, after the pressing piece 12 is placed in the hollow portion 13, the pressing piece 12 is located on the mounting plane, at this time, the fastener 111 contacts with the bottom surface of the pressing piece 12, and the pressing piece 12 is supported in the hollow portion 13 through the fastener 111.

The tablet 12 can be made of metal, high temperature resistant plastic, ceramic, etc. It should be noted that to avoid shorting the wafer 12 to the heating module 300. When the preforms 12 are made of a metal material, it is also necessary to perform an insulating treatment on the preforms 12.

Meanwhile, the shape of the liquid inlet 112 includes a round hole, a square hole, a rectangle, an ellipse, and other common hole shapes. In this embodiment, the speed of the liquid guiding heating module 300 is limited by the liquid guiding layer in the liquid collecting body 200, and the size of the liquid inlet 112 may include any size.
