Heating element, atomization module, atomizer and electronic atomization device

Abstract

This application discloses a heating element, an atomizing module, an atomizer, and an electronic atomizing device. It belongs to the field of aerosol generation technology. In the heating element of this application, by setting the heating wire to alternately connect a first part and a second part, and by having different resistance values ​​for the first and second parts, the temperatures of the first and second parts are different when the heating element is energized. Therefore, the part with higher resistance has a relatively higher temperature, and the part with lower resistance has a relatively lower temperature. Thus, the temperature distribution of the heating wire is also an alternating distribution of high and low temperatures, effectively avoiding high temperatures concentrated in the middle of the heating wire, which would cause excessive heat and carbon buildup at that location. Furthermore, the relatively higher temperature part in the first and second parts can directly transfer the high temperature to the adjacent relatively lower temperature part, thereby improving the heat dissipation effect of the heating element.

Description

Technical Field

[0001] This application relates to the field of aerosol generation technology, and more specifically, to a heating element, an atomizing module, an atomizer, and an electronic atomizing device. Background Technology

[0002] Electronic atomizing devices are devices that use atomizing components to heat an aerosol matrix, causing the heated aerosol matrix to atomize and generate an aerosol for users to inhale.

[0003] The core component of an electronic atomizing device is the heating element, and its heating effect directly affects the atomization effect. In existing technologies, for heating elements wound around the inner wall of a liquid guide, a mesh-like heating element is typically placed between the two leads of the heating element, with heating wire diameters and heat dissipation strips on the heating element. This structure suffers from a higher temperature in the middle of each heating wire diameter, leading to carbon buildup on the heating element. Therefore, the existing heating element structure needs improvement. Utility Model Content

[0004] The main purpose of this application is to provide a heating element, an atomizing module, an atomizer, and an electronic atomizing device to solve the problem that the excessive heat generated by the heating element during operation in the prior art easily leads to carbon buildup.

[0005] On the one hand, this application provides a heating element, the heating element comprising:

[0006] First pin and second pin; and

[0007] A heating element is connected between the first pin and the second pin, and the heating element includes at least one heating wire diameter;

[0008] The heating wire diameter includes multiple first parts and multiple second parts, with a second part connected between adjacent first parts, so that the first parts and second parts are alternately connected, and the resistance values ​​of the first parts and the second parts are different.

[0009] Furthermore, the resistance of the first part is greater than that of the second part, and when the heating element is energized, the first part can atomize the contacted aerosol matrix to generate an aerosol, while the second part cannot atomize the contacted aerosol matrix.

[0010] Furthermore, along the direction in which the heating wire extends, the cross-sectional area of ​​the first portion is smaller than the cross-sectional area of ​​the second portion.

[0011] Furthermore, when the heating element is in a flat state, the surface area of ​​the second part is greater than the surface area of ​​the first part.

[0012] Furthermore, when the heating element is in a flat state, the heating wire extends along a first straight line and connects between the first pin and the second pin.

[0013] Furthermore, the heating element includes three heating wire diameters, which are respectively connected between the first pin and the second pin.

[0014] Furthermore, when the heating element is in a flat state, the surface area of ​​the second part is greater than the surface area of ​​the first part in the plane in which the heating element is located.

[0015] On the other hand, this application also provides an atomizing module, the atomizing module including the heating element described in any of the above claims; and

[0016] The atomizing tube and the liquid guiding component are provided, wherein the liquid guiding component is at least partially curled and disposed inside the atomizing tube, and the heating element is disposed inside the liquid guiding component in a curled state.

[0017] Furthermore, this application also provides an atomizer, the atomizer including the aforementioned atomizing module; and

[0018] A liquid storage module is provided, and the atomizing module is inserted into the liquid storage module and together with the liquid storage module form a liquid storage chamber. The atomizing tube has a liquid passage hole, and the liquid passage hole is connected to the liquid storage chamber.

[0019] Furthermore, this application also provides an electronic atomizing device, which includes the aforementioned atomizer; and

[0020] A battery rod, which is connected to the atomizer and is used to supply power to the atomizer.

[0021] In the heating element of this application, the heating wire diameter is configured to include multiple first portions and multiple second portions, with a second portion positioned between adjacent first portions. This allows the first and second portions of each heating wire diameter to be alternately connected. Furthermore, by setting the resistance values ​​of the first and second portions to be different, the temperatures of the first and second portions are different when the heating element is energized. Consequently, the portion with higher resistance has a relatively higher temperature, and the portion with lower resistance has a relatively lower temperature. Therefore, the temperature distribution of the heating wire diameter is also varied. The alternating temperature distribution effectively avoids the concentration of high temperatures in the middle of the heating wire diameter, thus preventing carbon buildup in that area due to excessive temperature. In addition, the relatively high-temperature parts in the first and second parts can directly transfer the high temperature to the adjacent relatively low-temperature parts, resulting in better heat dissipation of the heating element. Compared to the heat dissipation strips in the prior art, which are fixedly connected to the heating wire diameter at only one end while the other end is free, the heating element in this application has higher overall structural strength, which helps to maintain its shape after the heating element is rolled up, thereby maintaining the stability of suction resistance and the stability of the sucking sensation.

Detailed Implementation

[0032] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise.

It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0035] Please see Figure 1-3As shown, in one aspect, this application provides a heating element 10, which includes a first pin 11, a second pin 12, and a heating element 13. The heating element 13 is connected between the first pin 11 and the second pin 12, and the heating element 13 includes at least one heating wire diameter 131. The heating wire diameter 131 generates heat when energized to heat the contacted aerosol matrix, so that the heated aerosol matrix is ​​atomized to generate aerosol.

[0036] The heating wire diameter 131 includes multiple first portions 1311 and multiple second portions 1312. A second portion 1312 is connected between adjacent first portions 1311, allowing the first portions 1311 and second portions 1312 to be alternately connected. The resistance values ​​of the first portions 1311 and second portions 1312 are different. This ensures that when the heating element 10 is energized, the temperatures of the first portions 1311 and second portions 1312 are different. Consequently, the portion with higher resistance has a relatively higher temperature, and the portion with lower resistance has a relatively lower temperature. Therefore, the temperature distribution of the heating wire diameter 131 is also an alternating distribution of high and low temperatures, effectively preventing high temperatures from concentrating in the middle of the heating wire diameter 131, thus avoiding carbon buildup at that location due to excessive temperature.

[0037] In addition, the relatively high-temperature portions of the first part 1311 and the second part 1312 can directly transfer the high temperature to the adjacent relatively low-temperature portions, thereby improving the heat dissipation effect of the heating element 10. Compared with the heat dissipation strip in the prior art, which is fixedly connected to the heating wire diameter 131 at only one end and left free at the other end, the heating element 10 of this application has a higher overall structural strength of the heating body 13, which is beneficial to maintaining the shape after the heating body 13 is rolled up, thereby maintaining the stability of the suction resistance and the stability of the sucking sensation.

[0038] In the embodiments of this application, the resistance of the first part 1311 is greater than the resistance of the second part 1312, and when the heating element 10 is energized, the heat emitted by the first part 1311 is higher than the heat emitted by the second part 1312. Therefore, when the heating element 10 is energized, the temperature of the first part 1311 is higher than the temperature of the second part 1312. The first part 1311 can atomize the contacted aerosol matrix to generate aerosol, while the second part 1312 cannot atomize the contacted aerosol matrix. Thus, the aerosol matrix is ​​heated and atomized only through the first part 1311, and the contacted aerosol matrix is ​​replenished to the first part 1311 through the second part 1312.

[0039] In an embodiment of this application, the resistance of the first part 1311 may be less than the resistance of the second part 1312, and when the heating element 10 is energized, the first part 1311 may not atomize the contacted aerosol matrix, while the second part 1312 may atomize the contacted aerosol matrix to generate aerosol.

[0040] In the embodiments of this application, the heating wire diameter 131 is made of the same material. Therefore, the first part 1311 and the second part 1312 are made of the same material. In the direction extending along the heating wire diameter 131, the cross-sectional area of ​​the first part 1311 is smaller than that of the second part 1312. Therefore, the resistance of the first part 1311 is greater than that of the second part 1312. When energized, the temperature of the first part 1311 is higher than that of the second part 1312. This allows the first part 1311 to heat the contacted aerosol matrix, causing the heated aerosol matrix to atomize and generate aerosol. Since the second part 1312 has a lower temperature, it cannot atomize the contacted aerosol matrix.

[0041] In addition, the second part 1312, which has a larger cross-sectional area, also has a larger surface area than the first part 1311. Therefore, the second part 1312 can supply aerosol matrix to the adjacent first part 1311 when the heating element 10 is energized, and can also quickly dissipate the heat emitted by the first part 1311 when the heating element 10 is not energized.

[0042] Furthermore, the cross-section of the first part 1311 may be, but is not limited to, any one of a circle, an ellipse, a rectangle, etc., and the cross-section of the second part 1312 may be, but is not limited to, any one of an ellipse, a rectangle, etc.

[0043] Further, please refer to Figure 1As shown, when the heating element 10 is in a flat state, the surface area of ​​the second part 1312 in the plane where the heating element 10 is located is larger than the surface area of ​​the first part 1311. Therefore, when the heating element 10 is in a curled state, the second part 1312 can have a larger contact area with the liquid guide 30 of the atomizing module 100, thereby providing a more sufficient supply of aerosol matrix to the first part 1311 and better limiting the liquid guide 30. This allows both the liquid guide 30 and the heating element 10 to maintain their curled shape, and the atomizing channel 40 formed by the liquid guide 30 and the heating element 10 can maintain its shape. This allows the electronic atomizing device with the atomizing module 100 to maintain a stable draw resistance and a stable inhalation sensation when used by the user.

[0044] Furthermore, when the heating element 10 is in a flat state, along the orthographic projection direction of the heating element 10, the shape of the first part 1311 is linear, and the shape of the second part 1312 can be circular, rectangular, etc.

[0045] When the heating element 10 is in a flat state, the heating wire diameter 131 extends along a first straight line and connects between the first pin 11 and the second pin 12, so that the heating wire diameter 131 is approximately straight. Compared with the existing heating wire diameter 131 which extends in a wavy shape, the straight heating wire diameter 131 is easier to process and easier to maintain its shape after being rolled.

[0046] In the embodiments of this application, please refer to Figure 1-3 As shown, the heating element 13 includes three heating wire diameters 131, which are respectively connected between the first pin 11 and the second pin 12, and the three heating wire diameters 131 are spaced apart from each other. By setting the three heating wire diameters 131, the heating element 10 has a larger heating area and a larger atomization amount when it is powered on.

[0047] On the other hand, please refer to 4-5 and combine them. Figure 1-3 As shown, this application also provides an atomizing module 100, which includes the heating element 10 described in any of the above claims. Therefore, the atomizing module 100 has all the above-mentioned beneficial effects, which will not be repeated here.

[0048] Furthermore, the atomizing module 100 also includes an atomizing tube 20 and a liquid guiding component 30. The liquid guiding component 30 is at least partially curled and disposed inside the atomizing tube 20, and the heating element 10 is disposed inside the liquid guiding component 30 in a curled state.

[0049] On the other hand, please refer to Figure 6-7 and combined Figure 1-5 As shown, this application also provides an atomizer 1000, which includes the atomizing module 100 described above. Therefore, the atomizer 1000 has all the above-mentioned beneficial effects, which will not be repeated here.

[0050] Furthermore, the atomizer 1000 also includes a liquid storage module, with the atomizing module 100 passing through it and together forming a liquid storage chamber 210. The liquid storage module includes a housing 220 and a base 230. The housing 220 has a nozzle 2201, and the base 230 is sealed and inserted into the end of the housing 220 away from the nozzle 2201. The nozzle 2201 has a first insertion portion 2202 facing the base 230, and the base 230 has a second insertion portion 2301 facing the nozzle 2201. The atomizing module 100 is sealed and inserted between the first insertion portion 2202 and the second insertion portion 2301, and together with the housing 220 and the base 230, forms the liquid storage chamber 210.

[0051] Furthermore, the liquid guiding component 30 includes a first sub-liquid guiding component 31 and a second sub-liquid guiding component 32. The first sub-liquid guiding component 31 is coiled and disposed inside the atomizing tube 20. The heating element 10 is coiled and disposed inside the first sub-liquid guiding component 31. The second sub-liquid guiding component 32 is coiled and disposed between the second insertion portion 2301 and the atomizing tube 20.

[0052] By setting the first sub-liquid guiding component 31 and the second sub-liquid guiding component 32, the liquid-locking ability of the atomizing module 100 can be effectively improved, and the risk of leakage of the aerosol matrix through the atomizing module 100 can be reduced.

[0053] The atomizing tube 20 has a liquid passage hole 21, which connects to the first sub-liquid guide member 31. The second insertion part 2301 has a liquid guide hole 2302, which connects the second sub-liquid guide member 32 and the liquid storage chamber 210. This allows the aerosol matrix in the liquid storage chamber 210 to enter the second sub-liquid guide member 32 through the liquid guide hole 2302, and the aerosol matrix on the second sub-liquid guide member 32 to enter the first sub-liquid guide member 31 through the liquid passage hole 21. This allows the heating element 10 to heat and atomize the aerosol matrix on the first sub-liquid guide member 31.

[0054] On the other hand, please refer to Figure 1-7As shown, this application also provides an electronic atomizing device, which includes the atomizer 1000 described above. Therefore, the electronic atomizing device has all the above-mentioned beneficial effects, which will not be repeated here.

[0055] Furthermore, the electronic atomizing device also includes a battery rod, which is connected to the atomizer 1000 and is used to supply power to the atomizer 1000 and to control the atomizer 1000 to work or stop working.

[0056] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0057] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.

[0058] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
