Description

Technical Field

[0002] See also Figure 1-2 In the traditional atomization heating solution, the combination of the electric heating wire 41 and the liquid-conducting cotton rope 42 is made by winding the electric heating wire 41 around the outer circumference of the liquid-conducting cotton rope 42. Although the structure is simple and easy to obtain, its structural strength is poor and it is easy to deform. It can only be assembled manually, and its consistency is difficult to guarantee.

[0003] Moreover, when the electric heating wire 41 and the liquid-conducting cotton rope 42 are working, liquid enters from both ends of the liquid-conducting cotton rope 42, and the liquid-conducting cotton rope 42 conducts the liquid to the electric heating wire 41. The airflow goes from the bottom of the electric heating wire 41 to the top, bringing out the heated atomized steam. The problems arising from this are: 1. Its liquid inlet method is relatively single, and it is difficult to adopt other liquid inlet methods according to different requirements. 2. Its heating method is circumferential heating, but the air entering from the bottom of the electric heating wire 41 is at room temperature, which is relatively low in temperature, while the air at the top of the electric heating wire 41 is atomized steam, which has a higher temperature. It is difficult to ensure uniform temperature in the atomization area, so the experience is poor, and problems such as carbon deposition and core sticking are prone to occur, affecting the user experience.

[0061] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present invention. However, it should be clear to those skilled in the art that the present invention may be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present invention.

[0062] See also Figure 3-11The atomizing unit 1 in the first embodiment of the present invention comprises a bracket 12 and a sheet-shaped heating element 11 arranged on the bracket 12, the heating element 11 comprises a heating portion 111, an electrode portion 112 and a fixing portion 113, the two sides of the heating portion 111 in the first direction a are bent upward in the same direction toward the third direction c, so that one side of the heating portion 111 in the third direction c is concave and the other side is arched, the heating portion 111 comprises a heating circuit 1111 electrically connected to the electrode portion 112, so that the heating circuit 1111 generates heat when the electrode portion 112 is energized; the fixing portion 113 is embedded in the bracket 12, and at least two fixing portions 113 are arranged on the two edges of the heating portion 111 and / or the electrode portion 112 in the first direction a and / or the second direction b;

[0063] The bracket 12 is provided with a cavity 12a opened to the first direction a, an air inlet 12b for gas to enter, and a vent 12c for gas to flow out, the air inlet 12b is connected to the vent 12c, the heating element 11 is arranged on the bracket 12, the heating part 111 is arranged at the opening of the cavity 12a, and the fixing part 113 is embedded in the bracket 12, so that the heating element 11 and the bracket 12 are firmly connected; the concave side of the heating part 111 faces the cavity 12a and defines a space for accommodating the heating element 111 with the cavity 12a. The liquid guide 21 is received and the receiving chamber 13 is used to contact the liquid guide 21 with the heating element 11. The bracket 12 is provided with a liquid inlet hole 12d leading to the receiving chamber 13, so that the liquid can enter the receiving chamber 13. The arched side of the heating portion 111 faces outward and is directly opposite to the air inlet direction of the air inlet 12b. The two sides of the heating portion 111 in the first direction a correspond to the vents 12c, so that the airflow can be blown toward the arched side of the heating portion 111 and flow through the two sides of the heating portion 111 in the first direction a.

[0064] The first direction a, the second direction b and the third direction c are not parallel to each other. Preferably, the first direction a, the second direction b and the third direction c are perpendicular to each other.

[0065] Thus, when the liquid guide 21 is provided in the containing chamber 13 and the liquid from the liquid inlet hole 12d is conducted to the heating element 11, the heating element 11 heats the liquid and atomizes it, and then the atomized gas is carried away by the airflow entering the air inlet 12b.

[0066] A liquid guide 21 may be provided in the receiving chamber 13 of the atomization unit 1. The liquid guide 21 contacts the concave side of the heating portion 111 and conducts the liquid entering the liquid inlet hole 12d to the heating element 11 for heating and atomization. The atomized gas is carried away by the airflow entering the air inlet 12b.

[0067] In the atomization unit 1, the bracket 12 mainly provides support strength for the heating element 11 so that the heating element 11 is not easily deformed. At the same time, it defines a containing chamber 13 for containing the conductive liquid 21 with the heating element 11, and compresses the conductive liquid 21 so that the conductive material and the heating element 11 are in direct contact with each other.

[0068] The liquid-conducting liquid 21 is disposed in the containing chamber 13 of the atomizing unit 1 , and is constrained and pressed from all sides by the bracket 12 , the heating element 11 , and the cover 124 , so as to play the role of conducting the liquid 21 .

[0069] The size of the liquid inlet hole 12d can limit the amount of liquid entering the liquid-conducting cotton, and can effectively prevent leakage caused by excessive liquid inlet.

[0070] Since the heating portion 111 is no longer circumferentially covered, different liquid inlet methods can be adopted according to requirements, and the liquid inlet hole 12d can be set at different positions, for example, it can be set at both ends of the heating element 11 in the second direction b; it can also be set at a position opposite to the concave side of the heating element 11.

[0071] The arched side of the heating element 11 is more compatible with the airflow, which can make the heat on the atomization surface more uniform. The heating element 11 mainly adopts common electric heating alloy metal sheets such as iron-chromium-aluminum, nickel-chromium alloy, stainless steel, titanium, titanium alloy, nickel-iron alloy, etc., and forms an electric heating circuit through cutting, corrosion and other processes. Then, it is shaped by a mold or a jig to form a heating element with the above shape. The liquid guide 21 can adopt porous liquid guide cotton or liquid guide cotton rope.

[0072] See also Fig. 20 In some embodiments, the two sides of the heating portion 111 in the first direction a are bent toward the third direction c, so that the heating portion 111 is arc-shaped. Since the arc has a smooth transition surface, it is more consistent with the flow of air.

[0073] See also Figure 21-23 In other embodiments, at least one portion of the heating portion 111 is bent along the axis of the second direction b, so that the two sides of the heating portion 111 in the first direction a are bent toward the third direction c. Fig.21 In the embodiment, the middle of the heating portion 111 is bent along the axis of the second direction b to form a right angle or an obtuse angle, so that the portions on both sides of the axis are bent toward the third direction c, and the angle α of the heating portion 111 along the axis of the second direction b is a right angle or an obtuse angle, specifically, it can be bent into a V shape. Figure 22-23 In the embodiment, the two sides of the heating portion 111 in the first direction a are bent along the axis of the second direction b respectively; the angle β can be designed differently. Fig. 22In the embodiment of the invention, the angle β at which the two sides of the heating portion 111 in the first direction a are bent along the axis of the second direction b can be a right angle, and the heating portion 111 is bent into a rectangular shape; Fig.23 In the embodiment, the angle β at which the two sides of the heating portion 111 in the first direction a are bent along the axis of the second direction b may be an obtuse angle, and the heating portion 111 is bent into a rectangular shape.

[0074] See also Fig. 20 The two sides of the electrode portion 112 in the first direction a are also bent toward one side of the third direction c, and have the same shape and degree of bending as the two sides of the heat generating portion 111 in the first direction a.

[0075] See also Fig. 20 The number of the fixing parts 113 is preferably multiple, each fixing part 113 includes a first part 1131 extending outward and a second part 1132 connected to the first part 1131, the second part 1132 is connected to the outer edge of the first part 1131, the second part 1132 protrudes in a direction perpendicular to or inclined to the extension direction of the first part 1131, and the fixing part 113 can be T-shaped.

[0076] See also Fig. 20 The electrode portion 112 includes two electrode portions 112 respectively arranged on both sides of the heating portion 111 in the second direction b. The electrode portion 112 extends outwardly in a direction parallel to the second direction b or in a direction forming a certain angle with the second direction b. In the first direction a, the size of the electrode portion 112 is equal to or smaller than the size of the heating portion 111.

[0077] The manufactured heating element 11 can be formed by in-mold injection molding with the bracket 12, and the fixing portion 113 is embedded in the bracket 12. The bracket 12 is made of high-temperature resistant plastic, and known high-temperature resistant plastics include PEEK, LCP, PPS, PI, PA46, etc. In this way, the atomizing heating bracket 12 provides very good supporting strength for the heating element 11, which can facilitate the realization of automated production in the subsequent assembly process.

[0078] See also Figure 3-6The bracket 12 includes a base 121 and two extensions 122 extending in the same direction from the base 121. The two extensions 122 are arranged at intervals in the second direction b. The heating portion 111 of the heating element 11 is arranged between the two extensions 122. The interval between the extension ends of the two extensions 122 forms an air inlet 12b. The interval between the portions of the two extensions 122 located beside the heating portion 111 forms an air vent 12c. The air vent 12c includes two air vents 12c located on both sides of the heating portion 111 of the heating element 11 in the first direction a. The edge of the heating element 11 can be embedded in the extension 122. The base 121 and the extension 122 are preferably integrally formed.

[0079] See also Fig.11 The electrode portion 112 includes two electrode portions 112 respectively arranged on both sides of the heat generating portion 111 in the second direction b, and the electrode portions 112 on both sides are respectively embedded in the protruding portions 122 on both sides.

[0080] See also Figure 3-11 The liquid inlet hole 12d is arranged at a position opposite to the concave side of the heating part 111, and is located on the upper part of the bracket 12, forming an upper liquid inlet method. The advantage of this is that the paths of the liquid reaching the various parts of the heating element 11 are relatively consistent, and the plastic supplied to the various parts of the heating element 11 is balanced, and there will be no problem of insufficient liquid supply in some parts. The existing atomization atomization unit 1 using a ceramic heating element 11 mostly adopts this liquid inlet method, so the atomization unit 1 of the present invention can be produced with the same structural size as this type of ceramic atomization atomization unit 1, and the remaining structure of the atomization device 3 can directly adopt the structural design of this type of ceramic atomization device 3. It only needs to replace the atomization component 2 to obtain an atomization experience different from the ceramic core. There is no need to reopen the mold for replacement, and the existing technology can be switched very quickly.

[0081] See also Figure 3-11 The bracket 12 includes a base 121 and a cover 124. The cavity 12a is provided in the base 121. Both sides of the cavity 12a in the third direction c are open to facilitate the subsequent loading of the guiding liquid 21 and the cover 124. The heating element 11 is provided at the lower open side, and the cover 124 is provided at the upper open side. The cover 124 covers the containing chamber 13, and the liquid inlet hole 12d is provided on the cover 124. Preferably, the number of the liquid inlet holes 12d is one or at least two, and the liquid inlet efficiency is controlled by the number or size of the liquid inlet holes 12d.

[0082] See also Figure 3-11 Preferably, the position where the cover 124 of the receiving chamber 13 is set is sunken to form an inner positioning step 12g for positioning the cover 124, and the cover 124 abuts against the inner positioning step 12g to restrict the liquid guide 21 in the receiving chamber 13 and ensure that the liquid guide 21 is in close contact with the heating element 11. Figure 3-11The outer side of the bracket 12 has an outer positioning step 12h for positioning the bracket 12. When the atomization unit 1 is applied to the atomization device 3, the outer positioning step 12h cooperates with the internal structure of the atomization device 3 to achieve the positioning of the atomization unit 1.

[0083] The atomizing unit of the second embodiment of the present invention is shown in Figure 12-19 The liquid inlet hole 12d includes two liquid inlet holes 12d respectively arranged on both sides of the bracket 12 in the second direction b, forming a two-side liquid inlet mode. The liquid inlet hole 12d preferably penetrates the receiving bin 13 in a straight line, so as to facilitate the arrangement of the liquid guide 21, such as a liquid guide cotton rope, and the two ends of the liquid guide 21 can be respectively located in the two liquid inlet holes 12d; or the liquid inlet hole (12d) penetrates the receiving bin (13) obliquely, and the second direction (b) is not parallel to the first direction (a) and the third direction (c).

[0084] See also Figure 12-19 The bracket 12 includes a base 121 and a cavity wall 123. The cavity wall 123 is arranged between at least two extensions. The cavity wall 123 is bent to form a cavity 12a open to the third direction c. At least part of the fixing portion 113 is embedded in the edge of the cavity wall 123. The bracket 12 is provided with an air outlet 12e. The air outlet 12e and the heating element 11 are respectively arranged on both sides of the bracket 12 in the third direction c, so that the gas flow sequentially flows through the air inlet 12b, the air vent 12c, the interval between the cavity wall 123 and the base 121, and the air outlet 12e, and takes away the aerosol generated by the heating element 11 heating and atomizing. The bracket 12 includes a cover 124. The cavity wall 123 is provided with a through hole 12f that penetrates the cavity 12a. The through hole 12f is located opposite to the concave side of the heating portion 111. The cover 124 is inserted into the through hole 12f and extends into the cavity 12a. When a liquid guide 21 is provided in the receiving chamber 13, the cover 124 squeezes the liquid guide 21 so that the liquid guide 21 contacts the heating element 11. Figure 12-19 In the embodiment, the bracket 12 is preferably made of high temperature resistant plastic, and its main function is to provide supporting strength for the heating element 11 so that the heating element 11 is not easily deformed. At the same time, it defines a containing chamber 13 for containing the conductive liquid 21 with the heating element 11, and compresses the conductive liquid 21 so that the conductive material and the heating element 11 are in direct contact with each other.

[0085] See also Figure 12-19The heating element 11 can be made of a hollow metal sheet or a metal wire. The arched side of the heating element 11 is more matched with the airflow, which can make the heat on the atomization surface more uniform. The main function of the cover 124 is to compress the liquid-conducting liquid 21 so that the liquid-conducting liquid 21 and the heating element 11 are in good direct contact. The liquid-conducting liquid 21 can be arranged in the containing chamber 13 of the atomization unit 1 to play the role of conducting the liquid 21. When the liquid inlet hole 12d is linearly connected with the containing chamber 13, the liquid-conducting liquid 21 can be passed through the containing chamber 13 and the liquid inlet hole 12d, and its two ends in the second direction b are not restricted.

[0086] Figure 12-19 In an embodiment, liquid inlet holes 12d are provided at both ends of the bracket 12 in the second direction b, i.e., the left and right ends. The heating element 11 is molded by in-mold injection molding so that the fixing portion 113 is embedded in the plastic bracket 12, so that the heating element 11 has better supporting strength, and the liquid guide 21 is inserted into the accommodating chamber 13 formed by the heating element 11 and the bracket 12. In this way, since the liquid-conducting liquid 21, such as the liquid-conducting cotton rope, is inserted into the accommodating chamber 13, in order to smoothly insert the liquid-conducting liquid 21 into the accommodating chamber 13, the liquid-conducting liquid 21 cannot be set very thick, otherwise it cannot smoothly pass through the accommodating chamber 13. If the liquid-conducting liquid 21 is set thinner, it can smoothly pass through the accommodating chamber 13, but the problem of poor contact between the heating element 11 and the liquid-conducting liquid 21 will arise. Therefore, a through hole 12f is opened on one side in the first direction a of the bracket 12, that is, the upper side, and a cover body 124 is set on the through hole 12f, so that the installed cover body 124 presses and compresses the liquid-conducting liquid 21, so that the liquid-conducting liquid 21 and the heating element 11 can be in good contact, thereby solving the problem of poor contact between the heating element 11 and the liquid-conducting liquid 21.

[0087] In the above embodiment, the bracket 12 is preferably made of plastic material, and the heating element 11 is combined with the bracket 12 by in-mold injection molding, that is, the heating element 11 is placed in an injection mold, and then the bracket 12 is formed by injection molding, and the bracket 12 is combined with the heating element 11.

[0088] In summary, the heating element 11 of the atomization unit 1 of the present invention has good strength, is easy to mass-produce automatically, has a larger atomization area than the traditional planar heating element, is more compatible with the atomization airflow direction, and has more uniform heat during the heating process. In addition, the atomization unit 1 can be used in electronic cigarettes, and the liquid guide 21 conducts the smoke liquid to the heating element for heating and atomization.

[0089] See also Figure 16-19 An atomization assembly 2 of one embodiment of the present invention comprises a liquid-conducting liquid 21 and an atomization unit 1 according to any one of claims 1 to 25, wherein the liquid-conducting liquid 21 is disposed in a receiving chamber 13 of the atomization unit 1 and contacts a heating element 11 to conduct liquid from a liquid inlet hole 12d to the heating element 11 for heating and atomization.

[0090] The atomizing assembly 2 adopts the combination of the atomizing unit 1 and the liquid guide 21. The liquid guide 21 is arranged in the storage chamber 13 of the atomizing atomizing unit 1, and is restricted and pressed from all sides by the bracket 12, the heating element 11, and the cover 124, so as to play the role of conducting the liquid 21; the arched side of the heating element 11 is more matched with the air flow, so that the heat of the atomizing surface can be more uniform; the bracket 12 provides support strength for the heating element 11, so that the heating element 11 is not easy to deform, and at the same time defines the storage chamber 13 for accommodating the liquid guide 21 with the heating element 11, and compresses the liquid guide 21 so that the liquid guide material and the heating element 11 are more evenly distributed. Direct contact is good; since the heating part 111 is no longer circumferentially covered, different liquid inlet methods can be adopted according to requirements, and the liquid inlet hole 12d can be set at different positions, for example, it can be set at both ends of the second direction b of the heating element 11; it can also be set at a position opposite to the concave side of the heating element 11; the heating element 11 is no longer made by manually winding an electric heating wire around the periphery of the liquid guide 21, but can be made by an in-mold injection molding process, the heating element 11 and the bracket 12 are in-mold injection molding, and the fixing part 113 is embedded in the bracket 12, which can facilitate automated production in the subsequent assembly process.

[0091] See also Figure 24-29 An atomizing device 3 according to an embodiment of the present invention comprises a housing 31 and an atomizing assembly 2 according to claim 26 arranged in the housing 31. A liquid storage tank 313, an air outlet channel 312 and an air inlet channel 311 are arranged in the housing 31. The liquid storage tank 313 is used to store liquid and is connected to the liquid inlet hole 12d of the atomizing assembly 2. The air inlet channel 311 is connected to the air inlet 12b of the atomizing assembly 2. The air outlet channel 312 is connected to the air vent 12c of the atomizing assembly 2, so that the gas is heated and atomized by the heating element 11 and brought out through the air inlet channel, the air inlet 12b, the heating element 11, the air vent 12c and the air outlet channel 312 in sequence. Specifically, Figure 24-26 In the embodiment, the atomizing device 3 comprises Figure 24-26 of Figure 7-11 The atomizing assembly 2 adopts the method of liquid inlet from above; Figure 27-29 In the embodiment, the atomizing device 3 comprises Figure 16-19 The atomization component 2 adopts a liquid inlet method at both ends horizontally.

[0092] Since the atomizer adopts the above-mentioned atomizer assembly 2, the liquid guide 21 is arranged in the storage chamber 13 of the atomizer atomizer unit 1, and is restricted and pressed from all sides by the bracket 12, the heating element 11, and the cover body 124, so as to play the role of conducting the liquid 21; the arched side of the heating element 11 is more matched with the air flow, so that the heat of the atomization surface can be more uniform; the bracket 12 provides support strength for the heating element 11, so that the heating element 11 is not easy to deform, and at the same time defines a storage chamber 13 for accommodating the liquid guide 21 with the heating element 11, and compresses the liquid guide 21 so that the liquid guide material and the heating element 11 are in direct contact with each other. Good; since the heating part 111 is no longer circumferentially covered, different liquid inlet methods can be adopted according to requirements, and the liquid inlet hole 12d can be set at different positions, for example, it can be set at both ends of the heating element 11 in the second direction b; it can also be set at a position opposite to the concave side of the heating element 11; the heating element 11 is no longer made by manually winding an electric heating wire around the periphery of the liquid guide 21, but can be made by an in-mold injection molding process, the heating element 11 and the bracket 12 are in-mold injection molding, and the fixing part 113 is embedded in the bracket 12, which can facilitate automated production in the subsequent assembly process.
