Description

Technical Field

[0001] The present invention relates to an atomization device product that atomizes a microporous heated liquid into steam for users to inhale, and specifically to a mesh sheet type porous heating atomization component and its heating atomizer. Background Art

[0002] Currently, there are mainly two liquid guiding and heating methods for the atomization heating components applied in this field: one is a cylindrical porous liquid guiding heating element, where liquid enters from the outer wall of the cylinder, and a spiral or coiled cylindrical mesh heating element is embedded on the inner wall of the cylinder. Such atomization heating components mainly have problems such as large dimensional tolerances in the production of the heating element, the heating element needs to be bent and wound, is prone to deformation, and the irregular heating element will affect the heating efficiency and heating uniformity, resulting in poor product consistency and low product production capacity. The other is a heating component with liquid entering from the upper porous material and a planar heating mesh embedded on the bottom surface. Such heating components mainly have problems such as a small heating area and a small amount of smoke, easy generation of condensate when the atomized steam contacts the outer shell, and easy separation of the heating element from the porous material, which is prone to burning and affecting the user experience.

[0071] Please refer to Figures 1 - 39, the present invention provides a technical solution: a mesh sheet-like porous heating and atomizing assembly, including a porous liquid guide 1 for sucking and conducting liquid and a planar sheet-like electric heating track 2 disposed inside the porous liquid guide 1. One or more planar sheet-like electric heating tracks 2 are provided. The planar sheet-like electric heating track 2 is used to heat the liquid to atomize the liquid. One or more through-flow air holes 11 are provided on the porous liquid guide 1. The planar sheet-like electric heating track 2 is a planar heating network composed of one or more heating tracks connected in parallel. One or more vertical or horizontal through-flow air holes 11 are provided on the porous liquid guide 1.

The through-flow air holes 11 on the porous liquid guide 1 are distributed on one side or both sides of a planar sheet-like electric heating track 2. When the through-flow air holes 11 on the porous liquid guide 1 are distributed on both sides of a planar sheet-like electric heating track 2, they can be distributed in a crosswise pattern of one left and one right or a side-by-side pattern of two left and two right. The through-flow air holes 11 on the porous liquid guide 1 are distributed in the middle of two planar sheet-like electric heating tracks 2. At least one surface of the inner wall of the through-flow air holes 11 on the porous liquid guide 1 is a flat straight surface. The planar sheet-like electric heating track 2 is embedded on the inner wall of the porous liquid guide 1 and is substantially parallel to the flat straight inner wall surface of the through-flow air holes 11. The distance between the planar sheet-like electric heating track 2 and the flat straight inner wall surface is between 0 and 0.5 mm. The cross-section of the through-flow air holes 11 on the porous liquid guide 1 is one of a rectangle, a square, a triangle, a trapezoid, a semi-circle, and an ellipse. The outer shape of the porous liquid guide 1 is one of a rectangle, a square, a triangle, a trapezoid, a circle, and an ellipse. When a plurality of through-flow air holes 11 are provided on the porous liquid guide 1, the sizes of the through-flow air holes 11 are equal or arranged in a distribution where the middle air flow hole is large and the air flow holes on both sides are small. When a plurality of through-flow air holes 11 are provided on the porous liquid guide 1, the spacing of the through-flow air holes 11 is evenly distributed or densely distributed in the middle and sparsely distributed on both sides. The planar sheet-like electric heating track 2 is a planar heating network formed by cutting, stamping, cutting, or etching a planar conductive sheet material, or a planar heating network formed by bending a conductive wire material, or a planar heating network formed by screen printing and 3D printing of conductive paste. The circuit arrangement of the planar sheet-like electric heating track 2 is a square wave type circuit, and one or more square wave type heating tracks are connected in parallel between the two electrodes of the heating sheet. The circuit arrangement of the planar sheet-like electric heating track 2 is a W-shaped circuit path, and one or more W-shaped heating track circuits are connected in parallel between the two electrodes.The circuit of the planar sheet-like electric heating track 2 is a circular mesh heating circuit, and the mesh arrangement is an array of circular meshes or a staggered array of circular meshes. The circuit of the planar sheet-like electric heating track 2 is a square format heating circuit, and the mesh arrangement is a square array grid. The planar sheet-like electric heating track 2 is a single S-shaped detour circuit, and the detour direction is one of the length direction detour or the width direction detour, and the spacing between the detour circuit lines is one of equal spacing, dense in the middle and sparse on both sides, and sparse in the middle and dense on both sides. The planar sheet-like electric heating track 2 is a single square spiral track circuit. There are two electrical connection parts at both ends of the planar sheet-like electric heating track 2, and the electrical connection parts protrude from the outer wall of the porous liquid conductor 1. The electrical connection parts can be wire-type lead electrodes or sheet-like contact electrodes.

[0072] See also Figures 30 - 33 , the present invention also provides a technical solution: a mesh sheet type porous heating atomizer, including the mesh sheet type porous heating atomizer assembly 3. It also includes a base 4 and an oil tank 5, the mesh sheet type porous heating atomizer assembly 3 is installed inside the oil tank 5, the base 4 is arranged at the mouth of the oil tank 5 and the mesh sheet type porous heating atomizer assembly 3 is limited inside the oil tank 5, and the base 4 is provided with a first electrode 61 and a second electrode 62, and the contact ends of the first electrode 61 and the second electrode 62 extend into the oil tank 5 and are electrically connected to the two ends of the plane sheet type electric heating track 2. The base 4 is provided with an air inlet 41, and the air inlet 41 is connected to the space where the plane sheet type electric heating track 2 is located, and the oil tank 5 has an air outlet channel 51 inside, and the air outlet channel 51 is connected to the space where the plane sheet type electric heating track 2 is located. The base 4 is provided with an electrode mounting hole 42, and the first electrode 61 and the second electrode 62 are installed in the electrode mounting hole 42. It also includes oil-locking silicone 7, which is sleeved on the upper surface and side of the mesh sheet-type porous heating atomization component 3, and the outer wall of the oil-locking silicone 7 is sealed and connected to the inner wall of the oil bin 5.

[0073] Figures 1 to 2 The mesh sheet-type porous heating atomization component 3 in some implementation cases of the patent of the present invention can be used in an atomizer to heat and atomize liquid, which includes a porous liquid-conducting body 1 for conducting liquid and a flat sheet-like electric heating track 2 for heating and atomizing liquid. The flat sheet-like electric heating track 2 is a flat sheet-like heating plate composed of one or more heating tracks. The flat sheet-like electric heating track 2 has the advantages of faster heating speed, uniform heat, and high thermal efficiency. There are one or more through-type pores on the porous liquid-conducting body 1, and the flat surface of the inner wall of the through-type air flow hole 11 is roughly parallel to the flat sheet-like electric heating track 2. When the through-type flat sheet-like electric heating track 2 starts to heat, the heat atomizes the liquid into steam, which is discharged from the through-type air flow hole 11.

[0074] Figures 3 to 5 When there are multiple through-flow air vents 11 in the porous liquid conductor 1 of the present invention, it is a schematic diagram of the arrangement of the through-flow air vents 11 inside the porous liquid conductor 1. When there are multiple through-flow air vents 11, according to the position and size of the silicone oil inlet hole, the arrangement of the through-flow air vents 11 can be adjusted. When the heating area is large, the through-flow air vents 11 can be divided into multiple ones arranged in the porous liquid conductor 1. When the through-flow air vents 11 are small, it is preferable to select that the through-flow air vents 11 are distributed on one side of the planar sheet-type electric heating track 2 (as Figure 4 shown). By doing so, the liquid inlet hole can be set on one side, which can save the space of the atomizer. When the heating area is large and the planar sheet-type electric heating track 2 is thin, for example, less than 0.08 mm, in order to ensure that the planar sheet-type electric heating track 2 does not deform or generate deformation inside the porous liquid conductor 1, it is preferable to select that the through-flow air vents 11 are distributed on both sides of the planar sheet-type electric heating track 2 (as Figure 3 shown). By doing so, the through-flow ones on both sides can fix the planar sheet-type electric heating track 2 during manufacturing, preventing deformation from causing uneven heating and poor atomization effect.

[0075] Figures 6 to 8 It is a schematic diagram of the positional relationship between the through-flow air vents 11 and the planar sheet-type electric heating track 2 of the present invention. According to the different distributions of the positions of the silicone liquid inlet holes, the distribution of the through-flow air vents 11 changes accordingly. When the silicone liquid inlet hole is on one side, the through-flow air vents 11 are arranged on the other side of the heating sheet ( Figure 7 ), when the silicone liquid inlet holes are on both sides, the through-flow air vents 11 are arranged on both sides of the heating sheet ( Figure 6 ). When the required calorific value and atomized steam are large, it is preferable to select two planar sheet-type electric heating tracks 2 to increase the atomization area. In this way, the through-flow air vents 11 are arranged in the middle of the two heating sheets.

[0076] Figure 13 Figure 14Schematic diagram of the distance relationship between the planar sheet-like electric heating track 2 of the present invention and the inner wall plane of the through-flow air passage hole 11. In some actual cases, when the plane of the planar sheet-like electric heating track 2 is flush with the inner wall plane of the through-flow air passage hole 11, the atomization effect is the best and the atomization thermal efficiency is relatively high. However, there is a problem that there is an easy gap between the planar sheet-like electric heating track 2 and the porous liquid guide 1, resulting in insufficient oil supply and burning. When the plane of the planar sheet-like electric heating track 2 is completely buried in the porous liquid guide 1 and the distance from the inner wall plane of the air hole is relatively far, the heat needs to be conducted through the porous liquid guide 1 to the inner wall of the through-hole to generate atomized steam, resulting in problems such as low thermal efficiency, small atomized steam, and large heat loss. Therefore, it is most appropriate that the distance between the plane of the preferred planar sheet-like electric heating track 2 and the inner wall plane of the through-flow air passage hole 11 is between 0 and 0.5 mm. The most suitable dimensional distance can be adjusted according to comprehensive factors such as structural strength, thickness and strength of the planar sheet-like electric heating track 2.

[0077] Figures 17 to 24 Several different forms of the planar sheet-like electric heating track 2 of the present invention. In some implementation cases, in combination with different powers output by the circuit and different required heating areas, the heating circuit track direction and grid connection method need to be adjusted. In some applications with high power and large area, it is preferably selected Figure 19 、 Figure 20 、 Figure 21 type of mesh grid-like planar sheet-like electric heating track 2. This type of planar sheet-like electric heating track 2 is a parallel connection of multiple heating lines, with a small resistance value, a large cross-section of the track, uniform heat, and a greater power-bearing capacity. In some applications with low power, it is preferably selected Figure 22 、 Figure 23 、 Figure 24 type of circuitous single heating track. This type of planar sheet-like electric heating track 2 is a single heating line, with a large resistance value, a small cross-sectional area of the track, and a small power-bearing capacity.

[0078] In some implementation cases, if the size of the through-flow air passage hole 11 and the suction volume during suction are just matched, the planar sheet-like electric heating track 2 generates heat evenly. When there are multiple through-flow air passage holes 11, the through-flow air passage hole 11 can preferably be selected Figure 25 as shown, the air flow holes are of the same size and are evenly distributed.

[0079] In some implementation cases, due to the principle of thermal radiation, the middle part of the planar sheet-like electric heating track 2 generates heat quickly, while the two sides generate heat slowly. The through-flow air passage hole 11 can preferably be selected Figure 26 as shown, the air flow holes are distributed in a pattern where the middle volume is large and the two sides are small.

[0080] In some embodiments, in order to maximize the thermal efficiency of the porous heating component, the atomization area is maximized while ensuring strength. Since the heat in the middle is slightly higher than that on both sides, it is preferable to make the through-flow air holes 11 Figure 27 as shown, with a distribution where the through-flow air holes 11 are dense in the middle and sparse on both sides.

[0081] In some embodiments, due to the overall design considerations of the atomizer, the through-flow air holes 11 are generally vertical through-flow air holes as Figure 28 shown. The advantage of this design is that the path of the atomized steam in the atomizer is short, and the atomized steam has less contact with the inner wall of the air flow channel in the atomizer, making it less likely to have the problem of condensate. In some embodiments, due to a relatively high power, a relatively high temperature of the atomized steam, or some special air intake structures, the through-flow air holes 11 can preferably be selected as Figure 29 shown, the horizontal through-flow air holes 11, where the air flow enters from one side and exits from the other side.

[0082] In some embodiments, generally preferably, the vertical through-flow air holes 11 are selected. The through-flow air holes 11 are straight cylinders as Figure 34 shown. In this way, the planar sheet-like electric heating track 2 can be exposed in the through-flow air holes 11 in the largest possible space, resulting in a larger atomization area and the highest thermal utilization efficiency. However, in some designs, the area of the through-flow air holes 11 is relatively large and the atomized steam is relatively dispersed. In this case, it is preferable to select Figure 35 the tapered through-flow air holes 11 that are narrower at the top and wider at the bottom as shown. Such through-flow air holes 11 can effectively gather the atomized steam, making the atomized steam more concentrated and the atomization more complete.

[0083] In some embodiments, as Figure 36 the second alternative for the front view direction of the through-flow air holes 11 as the front view direction of the through-flow air holes 11, it is designed as a stepped through-flow air hole 11 that is narrower at the top and wider at the bottom. In this way, it can solve the above-mentioned problem of dispersed atomized steam while fully maximizing the atomization area, making the atomized steam more concentrated and the atomization more complete. In actual experimental verification, this method can better solve the problem of dispersed atomized steam, making the atomized steam more concentrated and complete.

[0084] In some embodiments, as Figure 37As the third alternative in the front view direction of the through-flow air passage hole 11, the main purpose of such a design with a narrower lower part and a wider upper part is that when dealing with some liquids with relatively low viscosity, in the straight-through through-flow air passage hole 11, there will be problems such as liquid leakage when the liquid conducts to the inner wall of the through-flow air passage hole 11 and drops due to gravity, or when the suction force during user use is relatively large, the airflow will carry the atomized vapor upwards, causing the unatomized liquid to move upwards with the airflow and be inhaled by the user into the user's mouth, resulting in a poor user experience. Designing a through-flow air passage with a wider upper part and a narrower lower part can effectively solve the above problems, reducing the force of the airflow on the liquid on the inner wall of the through-flow air passage hole 11 when the user inhales. And Figure 38 The stepped air passage with a wider upper part and a narrower lower part shown can effectively prevent liquid leakage and the problem of liquid being inhaled into the user's mouth during actual implementation. The advantage of this air passage design is that it reduces the air intake volume of the airflow while keeping the atomization area unchanged, resulting in a higher thermal efficiency, not affecting the effect of the atomized vapor, and improving the user experience.

[0085] Such as Figure 30 is a three-dimensional schematic diagram of an atomizer in some implementation cases. In the implementation cases, we can assemble it in the following steps:

[0086] (1) Insert the porous liquid-conducting heating component into the oil-locking silica gel 7;

[0087] (2) Assemble the oil-locking silica gel 7 with the base 4, and the two electrode connection wires of the porous heating component pass through the electrode installation holes 42 of the base 4;

[0088] (3) Press the two electrode posts 6 into the electrode installation holes 42 of the base 4;

[0089] (4) Fill the oil storage chamber 5 with liquid, and install the assembled base 4 and silica gel into the oil storage chamber 5.

[0090] The components assembled in this way are very few, and the assembly is very convenient and fast, and automated assembly can be achieved.

[0091] Such as Figure 31 shows a schematic diagram of the working principle and airflow direction of this atomizer. When the user inhales at the air outlet channel 51 of the oil storage chamber 5, the air induction switch is turned on, power is supplied to both ends of the electrode, and the planar sheet-like electric heating track 2 generates heat, heating the liquid that conducts from the oil storage chamber 5 through the silica gel oil inlet and the porous liquid conductor 1 to the planar sheet-like electric heating track 2 into atomized vapor. The air entering through the air inlet hole of the base 4 passes through the planar sheet-like electric heating track 2 of the porous liquid-conducting heating and atomizing component, and the atomized vapor flows out through the air outlet channel 51 of the oil storage chamber 5.

[0092] In some embodiments of this patent, the through-flow air holes 11 on the porous liquid conductor 1, the shape and positional relationship of the planar sheet-type electric heating track 2, the mesh structure of the planar sheet-type electric heating track 2, and the corresponding application scenarios are clearly described. The above embodiments elaborate on their differences, advantages, and disadvantages, and can be used interchangeably with each other.

[0093] Advantages of the present invention: The present invention provides a mesh sheet-type porous heating and atomizing assembly and its heating atomizer that are conducive to mass production, have uniform heating, a large atomization area, and a large amount of smoke. The structure of this product is simple and conducive to assembly, and the atomization effect has good consistency, solving problems such as poor consistency of the liquid guiding material, difficult adjustment of the oil inlet volume, inability of traditional heating elements to control the heating power of each area as required, unsmooth matching of the heating area and the air flow channel, existence of ineffective heating areas, and low efficiency of using heat to atomize the liquid after the electrical energy of traditional heating elements is converted into heat energy. The design of the present invention is simple, with few parts, good structural strength of each component, and not easily deformed during the assembly process. Thus, the manufactured finished products have high consistency, are conducive to automated production, and improve production efficiency.
