[0001] The present application relates to the technical field of electronic equipment, and in particular to an electronic atomizer and a heating component thereof, and a heating circuit suitable for the electronic atomizer. Background Art

[0002] The heating component of the electronic atomizer is a component on the electronic atomizer that is used to heat the liquid to be atomized through the electrothermal effect, thereby atomizing the liquid to be atomized to form smoke.

[0003] In the related art, the atomization amount of the electronic atomizer is often changed by adjusting the power of the heating component (such as increasing the voltage loaded on the heating network or the current passing through the heating network). However, since the resistance of the existing heating component in the main circuit is relatively fixed, the heating temperature of the heating component also changes synchronously when the power of the heating component is adjusted, thereby making it impossible to maintain a relatively constant atomization temperature. That is, the heating component in the existing electronic atomizer cannot flexibly and independently adjust the atomization temperature and the atomization amount. Utility Model Content

[0011] In some embodiments of the present application, different heating nets among the two or more heating nets are wound around the same rotation axis so that their positive electrode connection parts and negative electrode connection parts are located on a cylindrical surface.

[0012] In some embodiments of the present application, the positive connection parts of different heating nets in more than two heating nets are located at the same circumferential position on the cylindrical surface; the negative connection parts of different heating nets in more than two heating nets are located at different circumferential positions on the cylindrical surface.

[0014] In some embodiments of the present application, the heating net further includes a net portion, which is disposed between the positive electrode connection portion and the negative electrode connection portion and is formed with hollow mesh holes.

[0015] Correspondingly, some embodiments of the present application also provide an electronic atomizer, comprising: a shell, liquid-conducting cotton and any of the aforementioned heating components; wherein the liquid-conducting cotton is accommodated in the shell and forms a heating cavity, the heating net in the heating component is arranged in the heating cavity, and the common wire and / or the independent wire at least partially extends to the outside of the heating cavity.

Two or more heating nets can also work together to obtain a larger amount of smoke.

[0047] The technical solutions in the embodiments of the present application will be described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application. In addition, it should be understood that the specific embodiments described herein are only used to illustrate and explain the present application, and are not used to limit the present application.

[0048] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the present invention pertains. The terms used herein in the specification of the present invention are intended only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0049] In this application, unless otherwise stated, directional words such as "upper" and "lower" generally refer to the upper and lower parts of the device in actual use or working state, specifically the drawing direction in the accompanying drawings; while "inner" and "outer" refer to the outline of the device. In addition, in the description of this application, the term "including" means "including but not limited to". The terms first, second, third, etc. are used only as labels and do not impose numerical requirements or establish an order.

[0050] In this application, "and / or" describes the association relationship of associated objects, indicating that there may be three relationships. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. A and B can be singular or plural.

[0051] In the present application, "at least one" means one or more, and "plurality" means two or more. "One or more", "at least one of the following" or similar expressions refer to any combination of these items, including any combination of single items or plural items. For example, "at least one of a, b, or c", or "at least one of a, b, and c" can all mean: a, b, c, ab (i.e., a and b), ac, bc, or abc, where a, b, c can be single or multiple, respectively.

[0052] Various embodiments of the present application may be presented in the form of a range; it should be understood that the description in the form of a range is only for convenience and brevity, and should not be understood as a rigid limitation on the scope of the present application; therefore, it should be considered that the range description has specifically disclosed all possible sub-ranges and single numerical values ​​within the range. For example, it should be considered that the range description from 1 to 6 has specifically disclosed sub-ranges, such as from 1 to 3, from 1 to 4, from 1 to 5, from 2 to 4, from 2 to 6, from 3 to 6, etc., as well as single numbers within the range, such as 1, 2, 3, 4, 5 and 6, so it applies regardless of the range. In addition, whenever a numerical range is indicated herein, it is meant to include any cited number (fractional or integer) within the indicated range.

[0053] The technical solution of the present application is described below in conjunction with the accompanying drawings. Figures 1 to 10 , the technical solution of this application is as follows:

[0054] Reference Figure 1 The heating component 100 provided in some embodiments of the present application can be integrated into an electronic atomizer 200 to heat the liquid to be atomized to form smoke. The heating component 100 includes: more than two heating nets 110 and more than two independent wires 120.

[0055] The heating net 110 may be made of a conductive metal material, which contacts the liquid to be atomized in the electronic atomizer 200, has a certain resistance value, generates heat when powered on, and heats the liquid to be atomized to atomize it. The heating net 110 includes a wiring portion. An independent wire 120 is only connected to the wiring portion of a heating net 110, that is, Figure 1 For more than two independent wires 120 , at least one of the independent wires 120 is directly connected to one of the heating nets 110 among the more than two heating nets 110 , but does not form a direct connection relationship with the other heating nets 110 .

[0056] When in use, each heating net 110 can be connected to components such as circuit boards and power supplies that energize and generate heat for the heating nets 110 through independent wires 120 connected thereto, so that these circuit boards, power supplies and other components can energize and generate heat for one of the heating nets 110 for a period of time, and energize another heating net 110 for another period of time, that is, each heating net 110 can work alternately, thereby reducing the risk of overheating and blackening of the heating net 110 due to long-term use and increasing the service life of the heating net 110.

[0057] By adopting the above scheme, through the coordinated arrangement of more than two heating nets 110 and independent wires 120, each heating net 110 can generate heat independently during use, so that each heating net 110 can be alternately connected to the circuit for operation, which is convenient for adjusting the resistance value of the connected circuit as needed, and then adjusting the heating temperature, that is, realizing the adjustment of the atomization temperature.

[0058] It is also possible to make several heating nets 110 work simultaneously as needed to obtain a larger amount of smoke, that is, to achieve the adjustment of the atomization amount.

[0059] For specific plans, refer to Figure 1 and Figure 2 , the wiring part includes a first wiring part 111 and a second wiring part 112, and the first wiring part 111 and the second wiring part 112 can be arranged at opposite ends of the heating network. The heating component 100 also includes: a common wire 130. Among them, a common wire 130 is electrically connected to the positive wiring parts 111 of more than two heating networks 110; and / or a common wire 130 is electrically connected to the negative wiring parts 112 of more than two heating networks 110. The common wire 130 is used to connect the heating networks 110, so that the positive wiring part 111 / negative wiring part 112 of the common wire 130 of each heating network 110 can be connected to the circuit board, power supply and other components that make the heating network 110 powered and heated.

[0060] More specifically, the positive electrode connection part 111 and the negative electrode connection part 112 of a heating network 110 are electrically connected to only one of the common wire 130 and the independent wire 120. That is, when the positive electrode connection part 111 of the heating network 110 is connected to the independent wire 120, the common wire 130 is connected to the negative electrode connection part 112 of the heating network 110; when the negative electrode connection part 112 of the heating network 110 is connected to the independent wire 120, the common wire 130 is connected to the positive electrode connection part 111 of the heating network 110, so that after the common wire 130 and the independent wire 120 are connected to components such as circuit boards and power supplies, the heating network 110 is connected to the circuit loop.

[0061] In an optional solution, it is defined that among two or more heating nets 110, different heating nets 110 have different resistances. That is, among two or more heating nets 110, the resistance values ​​of at least two heating nets 110 are different. For example, the resistance values ​​of all heating nets 110 can be set to be different.

[0062] By limiting the resistance values ​​of different heating nets 110 in more than two heating nets 110 to be different, when a single heating net 110 is working, a higher current can be output to the heating net 110 with a lower resistance value, so that the electric power of each heating net 110 is relatively consistent. In this way, when the heating temperature is adjusted, the amount of smoke generated can be relatively consistent.

[0063] To illustrate the invention, the drawings only disclose a scheme using a first heating network 110a, a second heating network 110b, a third heating network 110c, a first independent wire 120a, a second independent wire 120b, a third independent wire 120c and a common wire 130. Figures 1 to 4 As shown, the first independent wire 120a is connected to the positive electrode connection portion 111 of the first heating network 110a, and the second independent wire 120b is connected to the positive electrode connection portion 111 of the second heating network 110b. The third independent wire 120c is connected to the positive electrode connection portion 111 of the third heating network 110c, and the common wire 130 is connected to the negative electrode connection portion 112 of the first heating network 110a, the negative electrode connection portion 112 of the second heating network 110b, and the negative electrode connection portion 112 of the third heating network 110c.

[0064] For example, the resistance value of the first heating net 110 a may be 0.8 Ω, the resistance value of the second heating net 110 b may be 1.0 Ω, and the resistance value of the third heating net 110 c may be 1.2 Ω.

[0065] At this time, the first heating net 110a, the second heating net 110b and the third heating net 110c can be regarded as resistors in the circuit. Accordingly, the first independent wire 120a, the second independent wire 120b, the third independent wire 120c and the common wire 130 can be regarded as connecting the resistors to the pins in the circuit, thereby forming a "three-net four-pin variable resistor" structure.

[0066] It is understandable that, in actual implementation, fewer or more heating networks 110 and independent wires 120 may be provided as required, that is, the "three-network four-pin variable resistor" structure shown in the accompanying drawings should be regarded as an example of the invention, and should not be regarded as a limitation on the implementation of the invention.

[0067] In an alternative embodiment, referring to Figure 1 The heating net 110 can be laid flat so that the positive electrode connection portion 111 and the negative electrode connection portion 112 are respectively located at two ends of the heating net 110.

[0068] In another alternative embodiment, referring to Figures 2 to 3 The heating net 110 is wound so that the positive electrode connection part 111 and the negative electrode connection part 112 are located at different circumferential positions on a cylindrical surface, and the arc between the circumferential positions of the positive electrode connection part 111 and the negative electrode connection part 112 is defined as the arc of the opening 113, and different heating nets 110 in more than two heating nets 110 are defined to have different arcs of the opening 113.

[0069] In this embodiment, the heating net 110 is wound to form a cylindrical surface similar to a cylinder, and an opening 113 is formed on the cylindrical surface after the heating net 110 is wound. The positive electrode connection portion 111 and the negative electrode connection portion 112 are respectively located on both sides of the opening 113, so that the independent wire 120 and the end of the common wire 130 connected to the heating net 110 can be relatively closer, which is convenient for laying out the line. Different heating nets 110 in more than two heating nets 110 have different opening 113 curvatures, that is, the opening 113 formed after the heating net 110 is wound is inconsistent in size, which can facilitate the staggered arrangement of each independent wire 120, thereby facilitating the integration of the heating component 100 into the electronic atomizer 200.

[0070] In a specific implementation scheme, the heating net 110 is wound so that the positive electrode connection portion 111 and the negative electrode connection portion 112 are located at different circumferential positions on a cylindrical surface, and different heating nets 110 in the two or more heating nets 110 are arranged at different positions in the axial direction of the cylindrical surface, and each heating net 110 is arranged at intervals along the axial direction of the cylindrical surface. The common wire 130 and / or the independent wire 120 at least partially extend along the axial direction of the cylindrical surface, that is, the common wire 130 and / or the two or more independent wires 120 at least partially extend in substantially the same direction, which can also facilitate the integration of the heating component 100 on the electronic atomizer 200 and the layout of the circuit.

[0071] In a specific implementation, different heating nets 110 among the two or more heating nets 110 are wound around the same rotation axis L1 so that their positive electrode connection parts 111 and negative electrode connection parts 112 are located on a cylindrical surface, that is, each heating net 110 is linearly distributed along the rotation axis L1.

[0072] In a more specific embodiment, the positive electrode connection parts 111 of different heating nets 110 in more than two heating nets 110 can be located at the same circumferential position on the cylindrical surface. The negative electrode connection parts 112 of different heating nets 110 in more than two heating nets 110 are located at different circumferential positions on the cylindrical surface. At this time, the common wire 130 can be further connected to the positive electrode connection parts 111 of each heating net 110, and the negative electrode connection parts 112 of each heating net 110 can be connected to the corresponding independent wires 120, so that each independent wire 120 can be spaced apart from each other.

[0073] Or, refer to Figure 4, the negative electrode connection parts 112 of different heating nets 110 in more than two heating nets 110 can also be located at the same circumferential position on the cylindrical surface; the positive electrode connection parts 111 of different heating nets 110 in more than two heating nets 110 can be located at different circumferential positions on the cylindrical surface. In this case, the common wire 130 can be further connected to the negative electrode connection parts 112 of each heating net 110, and the positive electrode connection parts 111 of each heating net 110 can be connected to the corresponding independent wires 120, so that each independent wire 120 can be spaced apart from each other.

[0074] It can be understood that the distinction between the positive electrode connection part 111 and the negative electrode connection part 112 can be determined based on their relative connection positions with the power supply in the circuit loop that enables the heating network 110 to be energized and generate heat. For example, when the power supply provides direct current, the positive electrode connection part 111 can be the part of the heating network 110 connected to the positive pole of the power supply, and the negative electrode connection part can be the part of the heating network 110 connected to the negative pole of the power supply.

[0075] In some embodiments of the present application, reference Figure 4 The heating net 110 also includes a net portion 114, which is disposed between the positive electrode connection portion 111 and the negative electrode connection portion 112 and is formed with a hollow mesh 114a. The hollow mesh 114a can increase the contact area between the heating net 110 and the liquid to be atomized, and also facilitate the dissipation of the smoke generated after the heating net 110 is powered on and heated.

[0076] Reference Figures 5 to 7 Some embodiments of the present application also provide an electronic atomizer 200, including: a housing 210, a liquid-conducting cotton 220 and any of the aforementioned heating components 100. Figure 6 The liquid-conducting cotton 220 is accommodated in the shell 210 and forms a heating chamber 221. The heating network 110 in the heating component 100 is arranged in the heating chamber 221. The common wire 130 and / or the independent wire 120 at least partially extend to the outside of the heating chamber 221.

[0077] Specifically, refer to Figure 7 The housing 210 is formed with a receiving cavity 211 for placing the liquid-conducting cotton 220, and a notch 212 communicating with the receiving cavity 211. The liquid-conducting cotton 220 can extend out of the receiving cavity 211 from the notch 212, so that the liquid-conducting cotton 220 can absorb the liquid to be atomized from the outside of the receiving cavity 211. The heating net 110 is wrapped by the portion of the liquid-conducting cotton 220 located in the receiving cavity 211 and contacts the liquid-conducting cotton 220, so that when the liquid to be atomized soaks the liquid-conducting cotton 220 and the heating net 110 is powered on, the liquid to be atomized in the liquid-conducting cotton 220 can be heated to generate smoke.

[0078] The common wire 130 and / or the independent wire 120 extend out of the housing 210 from one end of the housing 210. At this time, referring to the figure, a fixing ring 230 can be fixedly connected at one end of the housing 210 through which the common wire 130 and the independent wire 120 pass through by means of thread connection, interference fit, etc., and the common wire 130 and the independent wire 120 are located between the outer wall of the fixing ring 230 and the inner wall of the accommodating cavity 211 formed by the housing 210, so that the common wire 130 and the independent wire 120 are squeezed by the interference of the outer wall of the fixing ring 230 and the inner wall of the accommodating cavity 211 formed by the housing 210, and the common wire 130 and the independent wire 120 are limited and fixed.

[0079] Other methods may also be used to limit and fix the common wire 130. For example, on the basis of setting the fixing ring 230, a through hole is opened on the fixing ring 230 for the common wire 130 and the independent wire 120 to pass through, and the interference fit between the hole wall of the through hole and the surface of the common wire 130 / independent wire 120 passing through the through hole is formed to achieve the limit fixation of the common wire 130 and the independent wire 120. The present application does not involve improvements to the specific fixing method of the common wire 130 and the independent wire 120 on the electronic atomizer 200. The above scheme is an example of the fixing method of the common wire 130 and the independent wire 120 on the electronic atomizer 200, and should not be regarded as a limitation on the actual implementation plan, and will not be repeated here.

[0080] Reference Figure 8 and Fig. 9 As shown, the positive electrode connection part 111 and the negative electrode connection part 112 of the heating network 110 in the heating component 100 of the present application can be connected to different independent wires 120 respectively, so that the heating component 100 of the present application can form a variety of circuit structures according to needs.

[0081] In order to enable those skilled in the art to fully understand the concept of the invention of the present application, some embodiments of the present application also provide a heating circuit suitable for an electronic atomizer, which is applied to the electronic atomizer and functions to heat the liquid to be atomized by using the electrothermal effect so as to complete atomization of the liquid to be atomized. The heating circuit suitable for the electronic atomizer includes: a power supply, a switch, and two or more heating networks.

[0082] Among them, the power supply can be regarded as a battery, an AC power supply, etc. that provides electric energy to the heating network according to the actual implementation situation, or it can be regarded as a combination of the above-mentioned battery or AC power supply and a circuit board that controls the heat generation of the heating network, which will not be repeated here. The power supply is electrically connected to the switch or the heating network to supply power to the switch or the heating network. The switch is connected in series with at least one heating network, or / and the switch is connected in parallel with at least one heating network, that is, the switch can be used to control whether the heating network is connected to the power supply to work.

[0083] In an alternative embodiment, referring to Figure 8 , exemplarily shows a specific implementation scheme in which a heating circuit suitable for an electronic atomizer includes a first resistor 301, a second resistor 302, a third resistor 303, and a first switch 304 connected in parallel with the first resistor 301, a second switch 305 connected in parallel with the second resistor 302, and a third switch 306 connected in parallel with the third resistor 303, wherein the first resistor 301, the second resistor 302, and the third resistor 303 represent that a heating circuit suitable for an electronic atomizer has three heating networks.

[0084] At this time, the first resistor 301, the second resistor 302, and the third resistor 303 are connected end to end in series. The first switch 304 can control whether the first resistor 301 is powered on, the second switch 305 can control whether the second resistor 302 is powered on, and the third switch 306 can control whether the third resistor 303 is powered on.

[0085] In this way, the first resistor 301 , the second resistor 302 , and the third resistor 303 can be connected to the main circuit by controlling the first switch 304 , the second switch 305 , and the third switch 306 to be turned on and off.

[0086] This is equivalent to forming a series circuit of the first resistor 301, the second resistor 302, and the third resistor 303 that can be selectively powered on.

[0087] Since the resistance connected to the main circuit can be dynamically adjusted through the first switch 304, the second switch 305, and the third switch 306, combined with the adjustment of the output voltage or output current of the power supply 320, a variety of atomization powers and atomization temperatures can be output.

[0088] As an optional solution, the first switch 304, the second switch 305, and the third switch 306 may be semiconductor switches integrated on a circuit board, such as MOS switches.

[0089] In some embodiments of the present application, a switch is electrically connected to a heating network through an independent wire; and two or more heating networks are electrically connected to a power source through a common wire.

[0090] Specifically, refer to Fig. 9 , exemplarily shows a specific implementation scheme in which a heating circuit suitable for an electronic atomizer includes a fourth resistor 307, a fifth resistor 308, a sixth resistor 309, a fourth switch 310 connected in series with the fourth resistor 307, a fifth switch 311 connected in series with the fifth resistor 308, and a sixth switch 312 connected in series with the sixth resistor 309. In the circuit of this embodiment, the fourth resistor 307, the fifth resistor 308, and the sixth resistor 309 represent that the heating circuit suitable for an electronic atomizer has three heating networks.

[0091] One of the switch ends of the fourth switch 310 is connected to the fourth resistor 307, one of the switch ends of the fifth switch 311 is connected to the fifth resistor 308, and one of the switch ends of the sixth switch 312 is connected to the sixth resistor 309, that is, the three switches are electrically connected to the corresponding three heating networks through independent wires. One end of the fourth resistor 307, the fifth resistor 308, and the sixth resistor 309 are all connected to the negative electrode of the power supply 320. That is, the three heating networks 110 are electrically connected to the negative electrode of the power supply 320 through a common wire.

[0092] In order to adjust the power and heating temperature respectively, the other ends of the fourth resistor 307 , the fifth resistor 308 , and the sixth resistor 309 are connected to the positive electrode of the power supply 320 through the fourth switch 310 , the fifth switch 311 , and the sixth switch 312 , respectively.

[0093] In this way, the fourth resistor 307 , the fifth resistor 308 , and the sixth resistor 309 can be connected to the main circuit by controlling the fourth switch 310 , the fifth switch 311 , and the sixth switch 312 to be turned on and off.

[0094] This is equivalent to forming a parallel circuit of the fourth resistor 307, the fifth resistor 308, and the sixth resistor 309 that can be selectively powered on.

[0095] Since the resistance connected to the main circuit can be dynamically adjusted through the fourth switch 310, the fifth switch 311, and the sixth switch 312, combined with the adjustment of the output voltage or output current of the power supply 320, a variety of atomization powers and atomization temperatures can be output.

[0096] As an optional solution, the fourth switch 310 , the fifth switch 311 , and the sixth switch 312 may be semiconductor switches integrated on a circuit board, such as MOS switches.

[0097] In some embodiments of the present application, the heating circuit for the electronic atomizer further includes: a controller. The controller is electrically connected to the power supply so that the power supply can supply power to the controller. Correspondingly, the switch includes two switch ends and a control end. The controller is electrically connected to the control end of the switch; one switch end of the switch is electrically connected to a heating network; and the other switch end of the switch is electrically connected to the power supply.

[0098] Specifically, refer to Fig.10, exemplarily shows a specific implementation scheme when the heating circuit suitable for the electronic atomizer includes the seventh resistor 313, the eighth resistor 314, the ninth resistor 315, the seventh switch 316 connected in series with the seventh resistor 313, the eighth switch 317 connected in series with the eighth resistor 314, the ninth switch 318 connected in series with the ninth resistor 315, and the controller 319 electrically connected to the seventh switch 316, the eighth switch 317, and the ninth switch 318. In the circuit of this embodiment, the seventh resistor 313, the eighth resistor 314, and the ninth resistor 315 represent that there are three heating networks in the heating circuit suitable for the electronic atomizer.

[0099] The seventh switch 316 includes a first switch terminal 316a connected to the positive pole of the power supply, a second switch terminal 316b connected to the seventh resistor 313, and a first control terminal 316c connected to the controller 319; the eighth switch 317 includes a third switch terminal 318a connected to the positive pole of the power supply, a fourth switch terminal 318b connected to the eighth resistor 314, and a second control terminal 318c connected to the controller 319; the ninth switch 318 includes a fifth switch terminal 318a connected to the positive pole of the power supply, a sixth switch terminal 318b connected to the ninth resistor 315, and a third control terminal 318c connected to the controller 319.

[0100] One end of the seventh resistor 313 , the eighth resistor 314 , and the ninth resistor 315 are all connected to the negative electrode of the power source 320 .

[0101] In this way, the controller 319 can control the on and off of each switch to connect each resistor to the power supply. Since the resistor connected to the main circuit can be dynamically adjusted through the seventh switch 316, the eighth switch 317, the ninth switch 318 and the controller 319, combined with the adjustment of the output voltage or output current of the power supply 320, a variety of atomization powers and atomization temperatures can be output.

[0102] As an optional solution, the seventh switch 316, the eighth switch 317, and the ninth switch 318 may be semiconductor switches integrated on a circuit board, such as MOS switches.

[0103] As an optional solution, the controller 319 may be a control chip integrated into a circuit board, such as an MCU chip.

[0104] Of course, the above solution can also use more resistors in series and parallel combination to form more circuit combinations.

It should be understood that these examples should be regarded as illustrations of feasible solutions when the concept of the invention is applied to practice, and should not be regarded as the only three limitations on the feasible circuit connection methods of the heating circuit applicable to the electronic atomizer.

[0105] In some embodiments of the present application, different heating nets among the two or more heating nets have different resistances, so that different heating temperatures for the atomized liquid can be obtained by connecting power to different heating nets at different times.
