Description

Technical Field

[0001] The present application relates to the field of atomization technology, and in particular to a heating element, an atomization component and an atomization device. Background Art

[0002] The atomization component can atomize the atomization matrix into an aerosol by heating. The atomization component is usually composed of a heating element and a liquid guide. The liquid guide can transfer the atomization matrix from the liquid storage tank to the surface of the heating element. When the heating element is heated, the atomization matrix is ​​atomized into an aerosol. Among them, the heating element is mainly welded with a heating wire / heating net and a pin. The conventional solder joints are arranged in a fixed position. When the atomization is working, the heat will be concentrated on the solder joint near the end of the heating circuit, causing the temperature to spread more easily to the solder joint and the pin in contact with the solder joint. The other solder joints far away from the heating circuit pass less current and lower temperature, and the heat loss of the entire heating element is large, which leads to reduced atomization efficiency.

Wherein similar elements in different embodiments adopt associated similar element numbers. In the following embodiments, many detailed descriptions are intended to enable the present application to be better understood. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, and methods.

[0034] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations, and the operation steps involved in each embodiment can also be replaced or adjusted in a sequence in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for the purpose of clearly describing a certain embodiment and do not mean that the composition and / or sequence are necessary.

[0035] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0036] like Fig.12 and Fig.13 As shown, the atomizing device 4000 is composed of an atomizing assembly 3000 and a power supply assembly 400. The power supply assembly 400 can provide necessary power to the atomizing assembly 3000, and the atomizing assembly 3000 can work under the action of the power supply. The atomization assembly 3000 is generally composed of a housing 301, a heating element 1000, a liquid-conducting liquid 302, and a liquid storage tank 303, wherein the housing 301 accommodates the heating element 1000, the liquid-conducting liquid 302, and the liquid storage tank 303 is connected to the liquid-conducting liquid 302, the heating element 1000 may be plate-shaped or cylindrical, the liquid-conducting liquid 302 is connected to and extends from the heating element 1000, and the liquid storage tank 303 stores a liquid-shaped atomization matrix inside. Specifically, a liquid storage may also be provided in the liquid storage tank 303, and the liquid-shaped atomization matrix is ​​adsorbed in the liquid storage, and the extended liquid-conducting liquid 302 contacts the liquid storage, and conducts the liquid-shaped atomization matrix by penetration, so that the atomization matrix can be directed to the heating element 1000. The heating element 1000 can atomize the atomization matrix into an aerosol required by the user by heating.

[0037] At present, in the conventional solder joints welded to the pins in the existing heating elements, two, three or four solder joints are arranged at the conductive part where each heating net is connected to the pin, and at least one of the solder joints is close to the end of the heating net, while the other solder joints are far away from the end of the heating net, for example, usually on the four corners of the heating net. The solder joints close to the end of the heating net mainly play the function of current conduction, while the solder joints far away from the end of the heating net usually only play the function of strengthening the structure. The current and heat are mainly concentrated on the solder joints close to the end of the heating net, which makes it easier for the temperature to diffuse to the welding line position, resulting in greater heat loss, and thus reducing the atomization efficiency.

[0038] Specifically, under the same conditions, the solder joint far away from the end of the heating network has a longer path from the end of the heating network relative to the solder joint close to the end of the heating network, and the resistance is greater, therefore, the current density is smaller; on the contrary, the current path in the solder joint close to the heating network is shorter, the current density is greater, the electric power is higher, the heat generation is greater, the temperature is more easily diffused to the location and surroundings of the solder joint, the heat loss is large, and the heat generation efficiency of the heating network is further reduced, thereby reducing the atomization efficiency.

[0039] Embodiment 1

[0040] The present embodiment provides an application in an atomizing device, wherein the atomizing device is used to heat and atomize the atomizing matrix into an aerosol. Figure 1-Figure 5 As shown, the heating body 1000 provided in this embodiment includes: a heating network 10, a conductive part 20, and a first electrical connection part 30 and a second electrical connection part 40. The heating network 10 includes at least two heating circuits 11. Along the length direction basically perpendicular to the heating circuit 11, the conductive part 20 is relatively arranged on both sides of the heating network 10, the first electrical connection part 30 and the second electrical connection part 40 are arranged on the conductive part 20, and the first electrical connection part 30 and the second electrical connection part 40 are located at the end Q of the heating circuit 11 along the length direction of the heating circuit 11. The extension direction of the end Q of each heating circuit 11 intersects at the middle of the connecting line of the first electrical connection part 30 and the second electrical connection part 40. The first electrical connection part 30 and the second electrical connection part 40 can both be connected to the power supply component 400 to provide electrical energy to the heating circuit 11 through the power supply component 400, so that the heating circuit 11 generates heat.

[0041] like Figure 1-Figure 3As shown, at least two heating circuits 11 are arranged in an interval and side by side manner, and the two sides of the heating net 10 are the two ends of the heating circuit 11, and the conductive parts 20 are respectively arranged on the two sides of the heating net 10. In this embodiment, there is a connecting line L between the first electrical connection part 30 and the second electrical connection part 40, and along the length direction of the heating circuit 11, the extension direction of the end Q of the heating circuit 11 intersects with the middle part P of the connecting line L between the first electrical connection part 30 and the second electrical connection part 40. In this way, when the power supply component 400 is connected to provide power through the external electrical connection line, the first electrical connection part 30 and the second electrical connection part 40 can both guide the current to the heating circuit 11, and because the distance between the first electrical connection part 30 and the end Q of the heating circuit 11 is substantially the same as the distance between the second electrical connection part 40 and the end of the heating circuit 11, the current distribution is more uniform, and the current can be more concentratedly guided to the heating circuit 11, so as to improve the heat generation efficiency of the heating circuit 11 and further improve the atomization efficiency.

[0042] like Figure 3 and Figure 6 As shown, Figure 3 Grayscale is used near the first electrical connection portion 30 and the second electrical connection portion 40 on the middle conductive portion 20 to indicate that current flows toward the heating circuit 11 .

[0043] It should be noted that a first electrical connection part 30 and a second electrical connection part 40 are provided at the end Q of each heating circuit 11, and the first electrical connection part 30 and the second electrical connection part 40 corresponding to each end Q satisfy that the end Q intersects at the middle part P of the connecting line L between the first electrical connection part 30 and the second electrical connection part 40 along the length direction of the heating circuit 11.

[0044] In particular, the middle portion P of the connecting line L can be considered to be close to the midpoint of the connecting line L. In this way, the first electrical connection portion 30 and the second electrical connection portion 40 can share the current in a more uniform manner. Compared with the method of making only one of the electrical connection portions closer to the end Q, the current distribution can be effectively improved, so that the current can be concentrated and directed to the heating circuit 11.

[0045] Here, it should be specially noted that the dotted line in the figure represents the extension of the connecting line L and the end Q. In reality, there is no extension of the connecting line L and the end Q. The dotted line is used in the figure only for the convenience of explanation.

[0046] In one embodiment of the present application, Figure 1-Figure 5 As shown, the heating network 10 is provided with two heating lines 11. Figure 1-Figure 3There is one fold line above the middle horizontal direction and another fold line below the middle horizontal direction. The two heating circuits 11 form a mesh. The left end of the upper heating circuit 11 is connected to a group of first electrical connection parts 30 and second electrical connection parts 40, and the right end is connected to a group of first electrical connection parts 30 and second electrical connection parts 40. A total of four groups of first electrical connection parts 30 and second electrical connection parts 40 are arranged on the two heating circuits 11.

[0047] In this embodiment, there is no limitation on the number of heating circuits 11, and the number of heating circuits 11 can also be three, four, etc., and correspondingly, six, eight, etc. groups of first electrical connection parts 30 and second electrical connection parts 40 are provided, which are specifically provided according to actual needs.

[0048] See also Figure 4 and Figure 5 As shown, the heating element 1000 provided in this embodiment also includes: a pin 200, which can electrically connect the conductive part 20 with the electrode of the power supply component 400 through the first electrical connection part 30 and the second electrical connection part 40, so that the power supply component 400 indirectly provides electrical energy to the heating circuit 11 through the first electrical connection part 30, the second electrical connection part 40 and the conductive part 20.

[0049] In a specific embodiment, two pins 200 are provided, and the two pins 200 are respectively provided on the two conductive parts 20 .

[0050] In addition, in the existing heating element, the heating net 10 and the pin 200 are usually welded by copper pillars. In order to avoid deformation of the heating net, it is usually necessary to Figure 1 The four corners of the conductive part 20 of the heating net 10 shown are provided with welding spots to strengthen the support of the heating net 10. In the present embodiment, the first electrical connection part 30 and the second electrical connection part 40 are welding spots formed by laser spot welding between the pin 200 and the conductive part 20. In other words, the pin 200 and the conductive part 20 are connected by laser spot welding. Compared with the existing connection method, the laser spot welding method will not be deformed and has sufficient strength. Compared with the scheme of setting some welding spots as a structure to enhance strength in the prior art, although the heat conduction ability of the heating circuit is enhanced in the scheme of laser spot welding adopted in the present application, the energy of laser spot welding is concentrated, and the thermal stress is less than the elastic deformation limit of the heating net, so that the pin 200 will not warp relative to the conductive part 20, thereby ensuring the strength of the structural connection.

[0051] In order to more intuitively illustrate the present solution and the method of setting welding points at the end of the heating net and the edge corner of the heating net in the above-mentioned existing solution, the following table compares the two different methods, wherein the present solution in the table refers to the solution provided by the present embodiment, and the previous solution refers to a solution in which one welding point is close to the end of the heating circuit and one welding point is at the edge of the conductive part. The table is as follows:

[0052]

[0053] Table 1

[0054]

[0055] Table 2

[0056] Combination Figure 6-Figure 8 As shown, it can be seen from the above that, with the heating element of this solution, the resistance of the two electrical connections to the heating circuit is basically the same, so that the two electrical connections can evenly guide the current to the heating circuit, thereby effectively reducing the current density and improving the heating efficiency of the heating circuit 11.

[0057] In a preferred embodiment of the present application, the extension direction of the end Q of the heating circuit 11 intersects at the midpoint of the connection line L between the first electrical connection portion 30 and the second electrical connection portion 40 , so that the current can be evenly distributed.

[0058] Furthermore, the line between the midpoint of the connecting line L and the end Q of the heating circuit 11 is perpendicular to the connecting line L. In this way, the path for the current to propagate to the heating circuit 11 through the first electrical connection portion 30 and the second electrical connection portion 40 can be shortened, further improving the heating efficiency of the heating circuit 11.

[0059] When the current propagates to the heating circuit 11 through the first electrical connection part 30 and the second electrical connection part 40, the current flows through the part of the conductive part 20, and the part of the conductive part 20 through which the current flows forms a certain contact resistance, thereby losing part of the electric energy. In order to ensure the strength and minimize the contact resistance, the distance between the first electrical connection part 30 and the second electrical connection part 40 is between 0.5 mm and 1.5 mm.

[0060] As a preferred embodiment of the present application, the distance between the first electrical connection portion 30 and the second electrical connection portion 40 is 1.0 mm.

[0061] Continue to see Figure 1-Figure 3 As shown, the heating circuit 11 has a wavy shape, so that a high-resistance heating circuit 11 can be manufactured under the same volume. It is not difficult to understand that if different resistance values ​​are required, the heating circuit can be bent into different tortuous path shapes.

[0062] In order to conduct heat more evenly, the heating element 1000 provided in the present application further includes: a first heat conductor 50 , and the heating circuit 11 has a preset connection position 12 , and the first heat conductor 50 is arranged between the preset connection positions 12 of two adjacent heating circuits 11 .

[0063] Here, it should be noted that the heating circuit 11 is wavy in shape, and the preset connection position 12 is the equipotential of the heating circuit 11. In other words, the heating circuit 11 has multiple equipotentials, and multiple first heat conductors 50 are provided to evenly dissipate the heat generated by the heating circuit 11.

[0064] Furthermore, the heating element 1000 provided in the present application also includes: a second heat conductor 60, which is arranged on the outside of the heating circuit 11, wherein the outside of the heating circuit 11 is a side where the preset connection position 12 is set for two adjacent heating circuits 11.

[0065] The heating circuit 11, the first heat conductor 50 and the second heat conductor 60 form a similar mesh structure, so that the heating element 1000 forms a roughly honeycomb-shaped mesh structure. The heating element of this structure has a certain tension or pressure resistance.

[0066] Gaps are formed between adjacent first heat conductors 50 , and the gaps can facilitate the dispersal of aerosol generated after heating and evaporation.

[0067] Here, it should be noted that, since the two ends of the first heat conductor 50 are respectively at the same potential as the two adjacent heating circuits 11, no current will flow through the first heat conductor 50, and it is only used to conduct heat. The second heat conductor 60 has only one end connected to the heating circuit 11, so no current will flow through it either, and the first heat conductor 50 and the second heat conductor 60 are only used to quickly conduct and dissipate the heat from the heating circuit 11.

[0068] The above-mentioned mesh structure characteristics of the heating element 1000 enable the heating element 1000 to have strong tension to support the liquid-conducting body 302, and not easily deformed, and no other supporting structure is needed for support or fixation, which not only saves costs, but also can conduct all the heat generated by the supporting heating circuit 11 to the liquid-conducting body 302. At the same time, the arrangement of the first heat conductor 50 and the second heat conductor 60 in the heating element 1000 can make the heat more uniform, avoid the problem of dry burning caused by excessive concentration of heat in a local area, and because the heating element 1000 is generating heat and conducting heat at the same time, the heating area is increased, the atomization matrix can be atomized quickly and the atomization amount is large, which greatly improves the atomization effect.

[0069] like Figure 3 As shown, Figure 3 Grayscale is used in the figure to represent the conduction and dissipation of heat generated by the heating circuit 11 by the first heat conductor 50 and the second heat conductor 60 .

[0070] Embodiment 2

[0071] The present embodiment provides an application in an atomizing device, wherein the atomizing device is used to heat and atomize the atomizing matrix into an aerosol. Fig. 9As shown, the heating element 1000 provided in this embodiment includes: a heating net 10, a conductive part 20 and at least two electrical connection parts 70. The heating net 10 includes at least two heating lines 11. The conductive parts 20 are relatively arranged on both sides of the heating net 10 along the length direction substantially perpendicular to the heating lines 11. At least two electrical connection parts 70 are arranged on the conductive part 20 and located at the end Q of the heating line 11. In other words, at least two electrical connection parts 70 are arranged at the end Q of each heating line 11, and each electrical connection part 70 located at the end Q of each heating line 11 is located on the adjacent area M of the connection between the end Q of the heating line 11 and the conductive part 20. Fig. 9 The dotted ellipse roughly frames the location of the adjacent area M.

[0072] It should be noted that at least two electrical connection parts 70 are provided in the vicinity of the connection between the end Q of each heating circuit 11 and the conductive part 20 .

[0073] like Fig. 9 As shown, at least two heating circuits 11 are arranged in an interval and side by side manner, the two sides of the heating net 10 are the two ends of the heating circuit 11, and the conductive parts 20 are respectively arranged on the two sides of the heating net 10. In this embodiment, the connection between the end Q of the heating circuit 11 and the conductive part 22 has an adjacent area M, and at least two electrical connection parts 70 are arranged in the adjacent area M. In this way, when the power supply component 400 is connected to the external electrical connection line to provide electric energy, at least two electrical connection parts 70 can guide current to the heating circuit 11. The adjacent area M can enable each electrical connection part 70 to provide current to the heating circuit, so that the current can be more concentratedly guided to the heating circuit 11, so as to improve the heat generation efficiency of the heating circuit 11 and further improve the atomization efficiency.

[0074] The heating network 10 is provided with two heating lines 11. Fig. 9 There is one fold line above the middle horizontal direction and another fold line below. The two heating circuits 11 form a mesh. The left end of the upper heating circuit 11 is connected to a group of at least two electrical connection parts 70, and the right end is connected to a group of at least two electrical connection parts 70.

[0075] In this embodiment, the number of the heating circuits 11 is not limited, and the number of the heating circuits 11 may be three, four, etc., and six, eight, etc. groups of electrical connection parts 70 are provided accordingly, depending on actual needs.

[0077] In a specific embodiment, two pins 200 are provided, and the two pins 200 are respectively provided on the two conductive parts 20 .

[0078] In addition, in the existing heating element, copper pillars are usually used to weld the heating net and the pins. In order to avoid deformation of the heating net, it is usually necessary to Figure 1 The four corners of the conductive part of the heating network shown are provided with welding spots to strengthen the support of the heating network. In the present embodiment, each electrical connection part 70 is a welding spot formed by laser spot welding between the pin 200 and the conductive part 20. In other words, the pin 200 and the conductive part 20 are connected by laser spot welding. Compared with the existing connection method, the laser spot welding method will not be deformed and has sufficient strength. Compared with the scheme of setting some welding spots as a structure to enhance strength in the prior art, although the heat conduction ability of the heating circuit is enhanced in the scheme of laser spot welding adopted in the present application, the energy of laser spot welding is concentrated, and the thermal stress is less than the elastic deformation limit of the heating network, so that the pin 200 will not warp relative to the conductive part 20, thereby ensuring the strength of the structural connection.

[0079] The heating element 1000 provided in the present application further includes: a first heat conductor 50 , and the heating circuit 11 has a preset connection position 12 , and the first heat conductor 50 is disposed between the preset connection positions 12 of two adjacent heating circuits 11 .

[0080] Here, it should be noted that the heating circuit 11 is wavy in shape, and the preset connection position 12 is the equipotential of the heating circuit 11. In other words, the heating circuit 11 has multiple equipotentials, and multiple first heat conductors 50 are provided to evenly dissipate the heat generated by the heating circuit 11.

[0081] Furthermore, the heating element 1000 provided in the present application also includes: a second heat conductor 60, which is arranged on the outside of the heating circuit 11, wherein the outside of the heating circuit 11 is a side where the preset connection position 12 is set for two adjacent heating circuits 11.
