Description

Technical Field

[0001] This invention belongs to the field of resistance heating atomization technology, and particularly relates to a heating element and heating component. Background Technology

[0002] Currently, most mainstream cotton wick atomizers on the market use a method of wrapping the heating element with cotton. The heating element is formed by rolling a nautilus shell or a flat etched sheet into shape using a jig, and then wrapping several layers of cotton fibers around the heating element. This method of operation is complicated and inefficient.

[0003] With industry development and technological innovation, a new type of heating element has emerged to meet the needs of automated mass production. This involves a substrate composed of several layers of flat cotton, with the heating element then bonded to the outermost layer. This method effectively differentiates the heating element from other products and offers unparalleled advantages in automated production and one-time production. However, it also presents some challenges. Specifically, the placement of the heating element relative to the atomizer's airflow path mainly falls into two categories: arrangement along the airflow path (e.g.,...). Figure 1 (The arrow indicates the direction of the airway) or arranged perpendicular to the direction of the airway (e.g., Figure 2 (The arrow indicates the airflow direction). The heating element is arranged along the airflow direction. Pressing the heating element support feet with a pressing component ensures a tight fit between the heating element and the flat cotton substrate, guaranteeing unobstructed airflow. However, the path between the electrode and the heating element electrode pins is long, resulting in significant power loss and uneven temperature distribution. Arranging the heating element perpendicular to the airflow direction shortens the path between the electrode and the heating element electrode pins, minimizing power loss. However, a tight fit between the heating element and the cotton substrate is difficult to guarantee. If a pressing component is used to press the heating element support feet, it will obstruct the airflow. Furthermore, in related technologies, the heating element electrode pins are mainly connected to the electrode by welding. However, because the sheet is thin, the heating element is prone to deformation after welding, increasing the risk of localized high temperatures and burn-in. Summary of the Invention

[0004] The technical objective of this invention is to provide a heating element and heating assembly, which aims to solve the problems in the prior art where the heating element has high power loss and uneven temperature distribution when arranged along the air passage, and where the heating element can easily obstruct the air passage when arranged perpendicular to the air passage.

[0005] To solve the above-mentioned technical problems, the present invention is implemented as follows: As one aspect of the present invention, a heating element is provided, comprising:

[0006] The heating element comprises N (N is a positive integer and N≥2) heating units connected in a stepped manner.

[0007] The support includes a plurality of support legs connected to the heating element. One end of each support leg is connected to the heating element, and the other end extends away from the heating element. The angle formed between the extending direction of the support leg and the sequential arrangement direction of the N heating elements is an acute angle or a right angle.

[0008] The electrode section includes two electrode pins. One end of each of the two electrode pins is connected to the heating unit located at both ends of the heating section, and the other end extends away from the heating section and is opposite to each other.

[0009] Furthermore, the angle formed between the extension direction of the electrode pin and the sequential arrangement direction of the N heating units is an acute angle.

[0010] Furthermore, the plurality of support legs are arranged in parallel.

[0011] Furthermore, the electrode pins are arranged parallel to the support feet.

[0012] Furthermore, the angle between the extending direction of the support leg and the sequential arrangement direction of the N heating units is a small angle of 15° to 75°.

[0013] Furthermore, each of the heating units is connected to at least one of the support feet.

[0014] Furthermore, each of the heating units located at both ends of the heating section is connected to at least one of the supporting feet, and the N-2 heating units located in the middle of the heating section are connected to two of the supporting feet.

[0015] Furthermore, the heating unit includes a heating portion in the form of a frame structure, and the heating portions of adjacent heating units are at least partially spliced ​​or overlapped.

[0016] Furthermore, the heating element includes a polygonal frame, and the mutually close edges of the polygonal frames of adjacent heating units are at least partially joined or overlapped.

[0017] Furthermore, the polygonal outer frame is a hexagonal outer frame.

[0018] Furthermore, the N heating units are arranged sequentially along two opposite sides of the hexagonal outer frame.

[0019] Furthermore, the polygonal frame is a rectangular frame.

[0020] Furthermore, the N heating units are arranged in a staggered manner along two opposite sides of the rectangular outer frame.

[0021] Furthermore, the heating part of the heating unit also includes a plurality of connecting beams located inside the rectangular outer frame and connected to at least two sides of the rectangular outer frame.

[0022] Furthermore, the length and width of the polygonal outer frame splicing or overlapping portion of adjacent heating units are both greater than or equal to the minimum set width.

[0023] As another aspect of the present invention, a heating assembly is provided, which includes an oil guide body, a pressing member, and the heating element; the oil guide body has an atomizing surface, and the heating elements of the heating element are attached to the atomizing surface; the pressing member is connected to the atomizing surface of the oil guide body and forms an air passage between the pressing member and the atomizing surface, and the N heating elements of the heating element are all located in the air passage, and the small angle formed by the sequential arrangement direction of the N heating elements and the extension direction of the air passage is an acute angle.

[0024] Furthermore, the support feet and electrode pins of the heating element are both attached to the atomizing surface, and each of the support feet and electrode pins is at least partially pressed between the pressing member and the atomizing surface.

[0025] Furthermore, the pressing component includes an air passage portion and a pressing portion. The air passage portion includes a through groove opened towards the atomizing surface, and the groove wall of the through groove surrounds the atomizing surface to form the air passage. The pressing portion is located on both sides of the air passage and is connected to the atomizing surface of the oil guide body. Each of the support feet and electrode pins of the heating element are at least partially pressed between the pressing portion and the atomizing surface.

[0026] Compared with the prior art, the heating element and heating component of the present invention have the following advantages: the heating part of the heating element is formed by multiple heating units arranged in a stepped manner. When the heating part is installed in the air passage of the atomizer, the small angle formed by the sequential arrangement direction of the multiple heating units and the extension direction of the air passage is an acute angle, that is, the heating part is arranged obliquely relative to the air passage. On the one hand, compared with the prior art in which the heating element is arranged along the air passage, the path of the electrode pin of the heating element can be shortened, and the power loss can be greatly reduced. On the other hand, compared with the prior art in which the heating element is arranged along the vertical air passage, not only can the pressing part be avoided from blocking the air passage, but the temperature distribution in the atomization chamber can also be more uniform, and the structure can be simpler.

[0037] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0039] In the description of this invention, it should be understood that the terms "center", "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0040] Furthermore, in the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0041] In this embodiment, as Figure 3 As shown, the heating assembly includes a heating element 1, an oil guide 2, and a pressing component 3.

[0042] Combination Figures 3-8 The heating element 1 includes a heating part, a support part, and an electrode part.

[0043] The heating element comprises N (N is a positive integer and N≥2) heating units 11 connected in a stepped manner.

[0044] The support includes several support legs 12 connected to the heating element. One end of each support leg 12 is connected to the heating element, and the other end extends away from the heating element. The angle formed between the extension direction of the support leg 12 and the sequential arrangement direction of the N heating elements 11 is an acute angle or a right angle.

[0045] The electrode section includes two electrode pins 13. One end of each electrode pin 13 is connected to a heating unit 11 located at both ends of the heating section, and the other end extends away from the heating section and is opposite to each other.

[0046] The oil guide body 2 has an atomizing surface 21, and the heating unit 11 of the heating element 1 is attached to the atomizing surface 21 of the oil guide body 2.

[0047] The pressing component 3 is connected to the atomizing surface 21 of the oil guide body 2, and forms an air passage 4 between the pressing component 3 and the atomizing surface 21. All N heating units 11 of the heating element 1 are located in the air passage 4, and the angle formed between the sequential arrangement direction of the N heating units 11 and the extension direction of the air passage 4 is an acute angle or a right angle.

[0048] In this design, the heating element 1 comprises multiple heating units 11 arranged in a stepped manner. When the heating element is installed within the air passage 4 of the atomizer, the angle between the sequential arrangement direction of the multiple heating units 11 and the extension direction of the air passage 4 is an acute angle, meaning the heating element is arranged obliquely relative to the air passage 4. This design offers advantages over existing technologies where the heating element is arranged along the air passage 4 (i.e., the angle between the extension direction of the heating element and the extension direction of the air passage 4 is 0°). Figure 1 As shown in the diagram (the arrow points in the direction of the extension of the airway 4), this shortens the path of the electrode pins 13 of the heating element 1, reducing power loss. Furthermore, compared to the prior art where the heating element is arranged perpendicular to the airway 4 (i.e., the angle between the extension direction of the heating element and the extension direction of the airway 4 is 90°, such as...), this design shortens the path of the electrode pins 13 of the heating element 1, reducing power loss. Figure 2 As shown in the diagram, the arrow points in the direction of the extension of the air passage 4. This not only prevents the pressing part 3 from blocking the air passage 4, but also makes the temperature distribution in the atomization chamber more uniform and the structure simpler.

[0049] The various components of the embodiments of the present invention will now be described in detail.

[0050] like Figure 3 As shown in the figure, and taking the direction shown in the figure as an example, in this embodiment, the oil guide body 2 is in the shape of a sheet, and its top surface is an atomizing surface 21, which is a flat surface.

[0051] The oil guide body 2 can be made of multiple layers of oil-guiding cotton or it can be a single piece of cotton. The material of the oil guide body 2 can also be a porous ceramic body.

[0052] The heating element 1, a key component of this embodiment, will now be described in more detail.

[0053] Combination Figures 4-8 The heating element 1 has a heating unit 11 that has a frame structure, and the heating parts of adjacent heating units 11 are at least partially spliced ​​or overlapped.

[0054] Furthermore, the heating element includes a polygonal frame, and the mutually close edges of the polygonal frames of adjacent heating units 11 are at least partially widened or overlapped.

[0055] Furthermore, the length and width of the polygonal outer frame splicing or overlapping portion of adjacent heating units 11 are both greater than or equal to the minimum set width, specifically, the minimum set width is greater than or equal to 0.06mm.

[0056] like Figure 3 and Figure 4As shown in the figure, in this embodiment, as one implementation of the heating element 1, the heating part of the heating unit 11 is a hexagonal frame structure, including a hexagonal outer frame, and the interior of the hexagonal outer frame is a hollow part; the heating units 11 are arranged sequentially along two opposite sides of the hexagonal outer frame, and the hexagonal outer frames of adjacent heating units 11 are joined together at their closest sides.

[0057] Specifically, such as Figure 4 As shown, there are 5 heating units 11. The heating part of the heating unit 11 is a regular hexagonal frame structure, including a regular hexagonal outer frame and a hollow part inside the regular hexagonal outer frame. The (i+1)th heating unit 11 (i is a positive integer and i≤4) is located to the lower right of the ith heating unit 11, and the upper left side of the regular hexagonal outer frame of the (i+1)th heating unit 11 is joined with the lower right side of the regular hexagonal outer frame of the ith heating unit 11, thereby connecting the (i+1)th heating unit 11 with the ith heating unit 11.

[0058] like Figure 4 As shown, the angle between the sequential arrangement direction of the heating units 11 and the extension direction of the airway 4 is 45°.

[0059] like Figure 4 As shown, the width of each side of the regular hexagonal frame is a, and a is greater than or equal to the minimum set width; and the width of the spliced ​​portion of the regular hexagonal frame of the adjacent heating unit 11 is b = 2a, and the length c of the spliced ​​portion is the side length of the regular hexagonal frame, and c ≥ a.

[0060] like Figure 4 As shown, the two electrode pins 13 are opposite to each other along the direction perpendicular to the air passage 4. It can be understood that the angle between the extension direction of the two electrode pins 13 and the sequential arrangement direction of the five heating units 11 is 45°.

[0061] like Figure 4 As shown, each heating unit 11 located at both ends of the heating section is connected to a support foot 12, and the support foot 12 extends in the opposite direction to the electrode pin 13 connected to the corresponding heating unit 11. Specifically, with Figure 4 Taking the direction shown as an example, the electrode pin 13 of the first heating unit 11 located in the upper left direction is connected to the left side of the heating unit 11 and extends to the left, and the corresponding support foot 12 is connected to the right side of the heating unit 11 and extends to the right; the electrode pin 13 of the fifth heating unit 11 located in the lower right direction is connected to the right side of the heating unit 11 and extends to the right, and the corresponding support foot 12 is connected to the left side of the heating unit 11 and extends to the left.

[0062] Three heating units 11 located in the middle of the heating section are respectively connected to two supporting legs 12, and the two supporting legs 12 extend in opposite directions. Specifically, with Figure 4 Taking the direction shown as an example, the support feet 12 corresponding to each heating unit 11 are connected to the left and right sides of the heating unit 11 respectively, and extend to the left or right respectively.

[0063] Therefore, it can be understood that all support feet 12 are arranged in parallel and parallel to the electrode pins 13, and the angle between the extending direction of the support feet 12 and the sequential arrangement direction of the five heating units 11 is 45°. In some embodiments, it can be understood that the support feet 12 may not be arranged in parallel, and the support feet 12 and the electrode pins 13 may not be parallel.

[0064] In some embodiments, the arrangement direction of the heating unit 11 can be adjusted, for example, in Figure 4 Based on the center of the third heating unit 11, the heating element is rotated 15° clockwise while keeping the extending directions of the airway 4, support foot 12, and electrode pin 13 unchanged. At this point, the smaller angle formed by the sequential arrangement direction of the heating units 11 and the extending direction of the airway 4 is 30°, and the smaller angle formed by the extending directions of the electrode pin 13 and support foot 12 and the sequential arrangement direction of the five heating units 11 is 60°. It can be understood that in this configuration, the path of the electrode pin 13 is relatively... Figure 4 The proposed solution is slightly longer, which increases the power loss of the devices. Considering this aspect... Figure 4 The proposed solution is superior.

[0065] Conversely, if in Figure 4 Based on the center of the third heating unit 11, the heating element is rotated counterclockwise by 15°, keeping the extending directions of the airway 4, support foot 12, and electrode pin 13 unchanged. At this point, the smaller angle formed by the sequential arrangement direction of the heating units 11 and the extending direction of the airway 4 is 60°, and the smaller angle formed by the extending directions of the electrode pin 13 and support foot 12 and the sequential arrangement direction of the five heating units 11 is 30°. It can be understood that in this configuration, the path of the electrode pin 13 is relatively... Figure 4 The solution is slightly shorter, which reduces the power loss of the device. However, the path of the support foot 12 connected to the heating unit 11 at both ends of the heating part is correspondingly longer, which is not conducive to fixing the heating unit 11.

[0066] Therefore, under normal circumstances, it is appropriate to control the small angle between the sequential arrangement direction of the heating units 11 and the extension direction of the airway 4 to be between 15° and 75°. At this time, when the extension direction of the support foot 12 and the electrode pin 13 is perpendicular to the extension direction of the airway 4, the angle between the extension direction of the support foot 12 and the electrode pin 13 and the sequential arrangement direction of the heating units 11 is between 75° and 15°.

[0067] like Figure 5 As shown in the figure, in this embodiment, as a second implementation of the heating element 1, the heating part of the heating unit 11 is a rectangular frame structure, including a rectangular outer frame and a hollow part inside the rectangular outer frame; the heating units 11 are arranged in a staggered manner along two opposite sides of the rectangular outer frame, and the adjacent sides of the rectangular outer frames of adjacent heating units 11 are widened together.

[0068] Specifically, such as Figure 5 As shown, there are 4 heating units 11. The (j+1)th heating unit 11 (j is a positive integer and j≤3) is located to the lower right of the jth heating unit 11. The upper side of the rectangular outer frame of the (j+1)th heating unit 11 is joined with the lower side of the rectangular outer frame of the jth heating unit 11 to connect the (j+1)th heating unit 11 to the jth heating unit 11.

[0069] like Figure 5 As shown, the width of each side of the rectangular outer frame is a, and a is greater than or equal to the minimum set width; and the width of the spliced ​​portion of the rectangular outer frame of the adjacent heating unit 11 is b = 2a, and the length c of the spliced ​​portion is half the length of the rectangular outer frame, and c ≥ a.

[0070] like Figure 5 As shown, the angle between the sequential arrangement direction of the heating units 11 and the extension direction of the airway 4 is 49°, the two electrode pins 13 are opposite to each other along the direction perpendicular to the extension direction of the airway 4, and the angle between the extension direction of the two electrode pins 13 and the sequential arrangement direction of the four heating units 11 is 41°.

[0071] like Figure 5 As shown, each heating unit 11 located at both ends of the heating section is connected to a support foot 12, and the support foot 12 extends in the opposite direction to the electrode pin 13 connected to the corresponding heating unit 11. The two heating units 11 located in the middle of the heating section are each connected to two support feet 12, and the two support feet 12 extend in the opposite directions.

[0072] Therefore, it can be understood that all the support feet 12 are arranged in parallel and parallel to the electrode pins 13, and the angle between the extension direction of the support feet 12 and the sequential arrangement direction of the four heating units 11 is 41°.

[0073] Similarly, by adjusting the length of the widened part between the heating units 11, the angle of the smaller included angle between the sequential arrangement direction of the heating units 11 and the extending directions of the air duct 4, the electrode pins 13, and the support feet 12 can be adjusted.

[0074] As Figure 6 shown in the figure, in this embodiment, as the third implementation manner of the heating element 1, the heating part of the heating unit 11 is also a rectangular frame structure, including a rectangular outer frame, and further including connecting beams located inside the rectangular outer frame and connected to the long sides of the rectangular outer frame. The rectangular outer frame and the connecting beams form a "day" shape. The setting of the connecting beams is beneficial to preventing the heating element from deforming due to heat and making the fit with the heating element smoother.

[0075] Specifically, as Figure 6 shown in the figure, the heating units 11 are arranged in sequence and offset along two opposite sides of the rectangular outer frame, and the mutually approaching sides of the rectangular outer frames of adjacent heating units 11 partially overlap.

[0076] More specifically, the number of heating units 11 is 4. The (j + 1)-th (j is a positive integer and j ≤ 3) heating unit 11 is located at the lower right of the j-th heating unit 11, and the left side of the rectangular outer frame of the (j + 1)-th heating unit 11 partially overlaps with the right side of the rectangular outer frame of the j-th heating unit 11, thereby connecting the (j + 1)-th heating unit 11 to the j-th heating unit 11.

[0077] As Figure 6 shown in the figure, the width of each side of the connecting beam and the rectangular outer frame is a, and a is greater than or equal to the minimum set width; and, the width b of the overlapping part of the rectangular outer frames of adjacent heating units 11 is a, and the length c of this overlapping part is c ≥ a.

[0078] As Figure 6 shown in the figure, the smaller included angle formed by the sequential arrangement direction of the heating units 11 and the extending direction of the air duct 4 is 58°. The two electrode pins 13 are背离 each other along a direction perpendicular to the extending direction of the air duct 4, and the smaller included angle formed by the extending directions of the two electrode pins 13 and the sequential arrangement direction of the four heating units 11 is 32°. [[ID=VI]]

[0079] As Figure 6 shown in the figure, each heating unit 11 is connected to two support feet 12; specifically, the two support feet 12 are respectively connected to the upper right and lower left corner positions of the heating unit 11. The electrode pin 13 of the 1st heating unit 11 is connected to the upper left corner position of this heating unit 11 and extends to the left, and the electrode pin 13 of the 4th heating unit 11 is connected to the lower right corner position of this heating unit 11 and extends to the right.

[0080] Therefore, it can be understood that all the supporting feet 12 are arranged in parallel and are parallel to the electrode pins 13. The smaller included angle formed by the extending direction of the supporting feet 12 and the sequential arrangement direction of the four heating units 11 is 32°.

[0081] As Figure 7 shown in , in this embodiment, as the fourth implementation manner of the heating element 1, the heating part of the heating unit 11 is also a rectangular frame structure, including a rectangular outer frame, and further including two connecting beams located inside the rectangular outer frame and respectively connected to the opposite sides of the rectangular outer frame. The rectangular outer frame and the connecting beams form a "field" shape. The "field" - shaped connecting beams have a good effect of preventing the heating element from deforming due to heat, and are more flat when贴合 with the heating element.

[0082] Specifically, as Figure 7 shown in , the heating units 11 are arranged in sequence and offset along two opposite sides of the rectangular outer frame, and the mutually - approaching sides of the rectangular outer frames of adjacent heating units 11 are partially widened.

[0083] More specifically, the number of the heating units 11 is 3. The (k + 1) - th (k is a positive integer and k ≤ 2) heating unit 11 is located at the lower - right of the k - th heating unit 11, and the upper side of the rectangular outer frame of the (k + 1) - th heating unit 11 and the lower side of the rectangular outer frame of the k - th heating unit 11 are partially widened, so as to connect the (k + 1) - th heating unit 11 and the k - th heating unit 11.

[0084] As Figure 7 shown in , the width of each connecting beam and each side of the rectangular outer frame is a, and a satisfies a ≥ the minimum set width; and, the width b of the widened part of the rectangular outer frames of adjacent heating units 11 is 2a, and the length c of this widened part satisfies c ≥ a.

[0085] As Figure 7 shown in , the smaller included angle formed by the sequential arrangement direction of the heating units 11 and the extending direction of the air duct 4 is 45°. The two electrode pins 13 deviate from each other along the direction perpendicular to the extending direction of the air duct 4, and the smaller included angle formed by the extending direction of the two electrode pins 13 and the sequential arrangement direction of the four heating units 11 is 45°.

[0086] As Figure 7 shown in , each heating unit 11 is connected to two supporting feet 12; specifically, the two supporting feet 12 are respectively connected to the upper - right and lower - left corner positions of the heating unit 11. The electrode pin 13 of the first heating unit 11 is connected to the upper - left corner position of this heating unit 11 and extends to the left, and the electrode pin 13 of the fourth heating unit 11 is connected to the lower - right corner position of this heating unit 11 and extends to the right.

[0087] Therefore, it can be understood that all the support feet 12 are arranged in parallel and parallel to the electrode pins 13, and the extension direction of the support feet 12 forms a smaller included angle of 45° with the arrangement direction of the four heating units 11 in sequence.

[0088] As Figure 8 shown in

[0089] Specifically, as Figure 8 shown in

[0090] In a more specific manner, the number of the heating units 11 is 4. The (j + 1)-th (j is a positive integer and j ≤ 3) heating unit 11 is located at the lower right of the j-th heating unit 11, and the upper side of the rectangular frame of the (j + 1)-th heating unit 11 and the lower side of the rectangular frame of the j-th heating unit 11 are partially widened, so as to connect the (j + 1)-th heating unit 11 with the j-th heating unit 11.

[0091] As Figure 8 shown in

[0092] As Figure 8 shown in

[0093] As Figure 8 shown in

[0094] Therefore, it can be understood that all the support feet 12 are arranged in parallel and parallel to the electrode pins 13, and the angle between the extension direction of the support feet 12 and the sequential arrangement direction of the four heating units 11 is 35°.

[0095] In the above embodiments of the heating element 1, the support foot 12 and electrode pin 13 of the heating element 1 are both attached to the atomizing surface 21 of the oil guide body 2, and each support foot 12 and electrode pin 13 is at least partially pressed between the pressing member 3 and the atomizing surface 21.

[0096] In practical applications, the heating element 1 can be formed by etching or stamping from metal or metal alloy. The heating part, support part and electrode part of the heating element 1 can be integrally formed and then attached to the oil guide body 2.

[0097] The pressing component 3 of this embodiment will now be described in detail.

[0098] Combination Figure 3 , Figure 4 and Figure 9 The pressing component 3 includes an air passage portion 31 and a pressing portion 32. The air passage portion 31 includes a through groove facing the atomizing surface 21, and the groove wall and the atomizing surface 21 enclose the air passage 4. The pressing portion 32 is located on both sides of the air passage 4 and is connected to the atomizing surface 21 of the oil guide body 2. Each support foot 12 and electrode pin 13 of the heating element 1 is at least partially pressed between the pressing portion 32 and the atomizing surface 21.
