Description

Technical Field

[0001] The present application relates to the field of electronic cigarettes, and in particular to a heating sheet structure of an atomizer core and an atomizer core. Background Art

[0002] The Mesh core atomizer core formed by the combination of a flat mesh heating element and liquid-conducting cotton is widely used in the heating and atomization of electronic cigarettes. The flat mesh heating element is often rolled into a columnar structure, and combined with the liquid-conducting cotton to form the core of the atomization device, becoming the liquid-conducting cotton atomizer core of the industry. Due to the existing technology, the flat mesh heating element used is a single heating element that is always powered and has a limited lifespan, which makes it impossible to draw too much atomized liquid. Therefore, it is necessary to improve the structure and working mode of the heating element to solve this problem, so as to extend the life of the heating element and draw large volumes. Utility Model Content

[0003] In order to solve the problems that the existing heating plate has a short life and cannot draw a large volume of atomized liquid, the present application provides a heating plate structure of an atomizer core and an atomizer core.

[0004] On the one hand, the heating sheet structure of an atomizer core provided in the present application adopts the following technical solution:

[0005] A heating plate structure of an atomizer core comprises a first heating plate and a second heating plate, wherein the first heating plate and the second heating plate are connected via conductive ribs, two ends of the first heating plate are respectively connected to a first pin and a second pin, and two ends of the second heating plate are respectively connected to a third pin and a fourth pin.

[0006] By adopting the above technical solution, multiple planar mesh heating sheets are combined together, a single heating sheet is partitioned by conductive ribs, and the power supply between the multiple heating sheets is controlled by connecting the circuit through multiple pins. The multiple heating sheet partitions work alternately, which can reduce the frequency of use of a single heating area and relieve the pressure of a single heating sheet working all the time, so as to achieve a longer service life. The combination of multiple heating sheets can meet the needs of large-capacity atomization at night.

[0007] Optionally, the conductive ribs include longitudinal connecting ribs, and the longitudinal connecting ribs are connected to a fifth pin.

[0008] By adopting the above technical solution, the setting of the fifth pin can make different heating areas of a single heating plate work independently, relieve the pressure of the single heating plate working all the time, and thus increase the life of the single heating plate.

[0009] Optionally, the longitudinal connecting ribs are connected to transverse supporting ribs, and the transverse supporting ribs are arranged along the length direction of the gap between the first heating sheet and the second heating sheet. A plurality of transverse supporting ribs are provided, and two adjacent transverse supporting ribs are respectively provided at both ends of the first heating sheet or at both ends of the second heating sheet.

[0010] By adopting the above technical solution, the transverse support ribs are rolled into a C shape together with the heating sheet during use, which plays a role in supporting and increasing the strength of the heating sheet, avoiding problems such as shrinkage caused by high temperature when the heating sheet is working. The transverse support ribs themselves are not connected to the circuit, and the length can be changed appropriately, which will not cause adverse conditions such as short circuit of the heating sheet.

[0011] Optionally, a plurality of longitudinal connecting ribs are provided.

[0012] By adopting the above technical scheme, the longitudinal connecting ribs not only play the role of connecting the conductive circuit of the first heating plate and the second heating plate, but also play a longitudinal supporting role. When each heating plate is working, the supporting force of the longitudinal connecting ribs is greater than the contraction force of the liquid-conducting cotton after being heated, thereby preventing the liquid-conducting cotton from shrinking due to heat and causing blockage.

[0013] Optionally, the length of the first heating sheet is greater than the length of the second heating sheet.

[0014] By adopting the above technical solution, the distance between the pins at both ends of the first heating plate is greater than the length of the pins at both ends of the second heating plate, thereby facilitating the installation of each pin without causing interference.

[0015] Optionally, the conductive ribs divide the first heating plate into two symmetrical heating areas, and the conductive ribs divide the second heating plate into two symmetrical heating areas.

[0016] By adopting the above technical solution, the heating areas of the first heating plate and the second heating plate are symmetrical structures, so that the heating body has better supporting force and can better support the liquid-conducting cotton, preventing the heating plates and the liquid-conducting cotton from loosening and causing the core to become sticky.

[0017] Optionally, the conductive ribs include a first longitudinal connecting rib, a second longitudinal connecting rib and a transverse supporting rib, the first longitudinal connecting rib is connected to the first heating plate, the second longitudinal connecting rib is connected to the second heating plate and is staggered with the first longitudinal connecting rib, and the first longitudinal connecting rib and the second longitudinal connecting rib are connected via a transverse supporting rib.

[0018] By adopting the above technical solution, a combination of longitudinal reinforcement and transverse reinforcement is used for connection. The longitudinal reinforcement can be extended to any heating area of ​​a single heating plate without affecting the normal operation of the heating plate. In addition, the connection method of transverse reinforcement and vertical reinforcement is adopted to support the blank part between the first heating plate and the second heating plate, so that the structural strength of the heating plate is higher.

[0019] On the other hand, the present application provides an atomizer core adopting the following technical solution:

[0020] An atomizer core comprises a fixed bracket, liquid-conducting cotton and a fixed plug, and also comprises the above-mentioned heating sheet structure, wherein a mounting hole is arranged in the fixed bracket, the liquid-conducting cotton is located in the mounting hole, the heating sheet structure is wound and sleeved in the liquid-conducting cotton, and fits with the liquid-conducting cotton, the fixed plug is used to seal the liquid-conducting cotton and the heating sheet structure in the mounting hole, the first heating sheet and the second heating sheet are arranged at intervals along the axial direction of the mounting hole, and the first pin, the second pin, the third pin and the fourth pin pass through the fixed plug and extend out of the fixed bracket.

[0021] By adopting the above technical solution, the atomizer core adopts the above heating sheet structure, which can also reduce the use frequency of a single heating area to achieve a longer service life and support the effect of sucking a larger volume of atomized liquid.

[0022] Optionally, a vent hole is formed through the fixing plug, the vent hole is connected with the mounting hole to form an air flow channel, and the air flow channel passes through the fixing bracket.

[0023] By adopting the above technical solution and setting the air flow channel, the gas can enter the heating plate and flow out from the heating plate, thereby realizing the user's inhalation.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. The heating sheet structure of the present application combines multiple flat mesh heating sheets together, spreads liquid guide cotton on the heating element, and controls the power supply between the multiple heating sheets through multiple pin external circuits, so that the multiple heating sheets work in turn, which can reduce the frequency of use of a single heating area to achieve a longer service life and support the suction of a larger capacity of atomized liquid.

DETAILED DESCRIPTION

[0036] The following is combined with Figure 1-9 This application is described in further detail.

[0037] The directional words such as "upper", "lower", "left", "right", "front", and "back" in this application only represent the relative positions in the drawings and are for the convenience of describing this application. They do not represent the absolute positions of the products and should not be regarded as limitations on this application.

[0038] Example 1

[0039] The present application discloses a heating plate structure of an atomizer core. Figure 1As shown, the heating sheet structure of the atomizer core includes a first heating sheet 1 and a second heating sheet 2. The first heating sheet 1 and the second heating sheet 2 are connected by a conductive rib 3. The first heating sheet 1 is connected to a first pin 4 and a second pin 5 at both ends, and the second heating sheet 2 is connected to a third pin 6 and a fourth pin 7 at both ends. In this embodiment, the first heating sheet 1 and the second heating sheet 2 have the same structure. Specifically, taking the second heating sheet 2 as an example, its structure is a planar mesh structure, such as Figure 2 As shown, it includes an effective heating section 21, two electrode parts 22 arranged at both ends of the effective heating section 21, and an ineffective connection section 23 (or heat dissipation rib) extending outward from the effective heating section 21, and the electrode part 22 is used to connect the pins for powering on.

[0040] When the heating sheet structure is applied to the atomizer core, Figure 3 As shown, the first heating sheet 1 and the second heating sheet 2 need to be rolled into a C shape when in use and placed in the liquid guiding cotton 16 of the atomizer core. The liquid guiding cotton 16 fits tightly with each heating sheet. When the atomizer core is energized, the heating sheet structure generates heat, and the atomized liquid on the liquid guiding cotton 16 is heated to become gas, which is sucked into the mouth of the smoker for inhalation.

[0041] In this embodiment, the conductive ribs 3, on the one hand, connect the first heating sheet 1 and the second heating sheet 2 to improve the strength of the two after winding, and on the other hand, divide the first heating sheet 1 and the second heating sheet 2 into zones to achieve alternating heating of the zones of a single heating sheet, thereby improving the life of the heating sheet. In addition, due to the increase in the area of ​​the heating sheet, the volume of the liquid-conducting cotton matched with the heating sheet is also larger, and the heated atomized liquid is also more, meeting the demand for large-capacity suction.

[0042] In this embodiment, the length of the first heating sheet 1 is greater than that of the second heating sheet 2. Accordingly, the pin spacing at both ends of the first heating sheet 1 is greater than the pin length at both ends of the second heating sheet 2, so that the installation of each pin will not cause interference.

[0043] like Figure 1 As shown, the working principle of the heating sheet structure of this embodiment is:

[0044] The first heating sheet 1 and the second heating sheet 2 are combined together through the conductive ribs 3 to form a heating sheet that works alternately in multiple modes. Among them, the conductive ribs 3 divide the first heating sheet 1 into heating area A and heating area B, and the conductive ribs 3 divide the second heating sheet 2 into heating area C and heating area D, and the two heating sheets form four heating areas. By controlling the working mode of the four pins, the function of using multiple modes alternately is realized. Preferably, the heating area A and the heating area B are symmetrical structures, and the heating area C and the heating area D, so that the heating structure has better supporting force, can better support the liquid-conducting cotton, and prevent the loosening between each heating sheet and the liquid-conducting cotton 16 from causing the core to stick.

[0045] When the first pin 4 and the third pin 6 are connected to the circuit to work, the upper left heating area A and the lower left heating area C are in operation.

[0046] When the first pin 4 and the fourth pin 7 are connected to the circuit to work, the upper left heating area A and the lower right heating area D are in operation.

[0047] When the first pin 4 and the second pin 5 are connected to the circuit to work, the upper heating area A and the heating area B are in operation.

[0048] When the third pin 6 and the fourth pin 7 are connected to the circuit to work, the lower heating area C and the heating area D will work.

[0049] When the third pin 6 and the second pin 5 are connected to the circuit to work, the upper right heating area B and the lower left heating area C are in operation.

[0050] When the fourth pin 7 and the second pin 5 are connected to the circuit to work, the upper right heating area B and the lower right heating area D are in operation.

[0051] The above are the 6 working modes of the multifunctional alternating working heating sheet. Any combination of two leads of the four extended pins can realize the heating function. Each heating circuit works alternately to relieve the pressure of a single heating sheet working all the time, thereby increasing the life of the heating sheet and meeting the needs of large-capacity atomization. In addition, when multiple heating sheets are used in combination, the heat dissipation ribs on both sides are longer than those of a single heating sheet, and the supporting effect is better. During use, it can avoid the problems of collapsed holes and blocked holes caused by the heating sheet becoming smaller.

[0052] Example 2

[0053] like Figure 4 As shown, the embodiment of the present application discloses a heating sheet structure of an atomizer core. The difference between this embodiment and embodiment 1 is that:

[0054] In this embodiment, the conductive ribs 3 include longitudinal connecting ribs 8 , and the longitudinal connecting ribs 8 are connected to the fifth pins 10 .

[0055] The fifth pin 10 can be connected to the circuit with any of the other four pins to work, and can also work alternately. The alternating use of multiple pins can realize the function of changing the resistance value. The working method of the circuit connected to the first pin 4, the second pin 5, the third pin 6 and the fourth pin 7 has been described in Example 1, and will not be discussed here. This embodiment focuses on the working condition when the fifth pin 10 is connected to the circuit.

[0056] When the first pin 4 and the fifth pin 10 are connected to the circuit to work, the heating area A works alone.

[0057] When the third pin 6 and the fifth pin 10 are connected to the circuit to work, the heating area C works alone.

[0058] When the second pin 5 and the fifth pin 10 are connected to the circuit to work, the heating area B works alone.

[0059] When the fourth pin 7 and the fifth pin 10 are connected to the circuit to work, the heating area D works alone.

[0060] This embodiment provides the fifth pin 10 to better utilize the feature that each heating area works independently.

[0061] Example 3

[0062] like Figure 5 As shown, the embodiment of the present application discloses a heating sheet structure of an atomizer core. The difference between this embodiment and embodiment 1 is that:

[0063] In this embodiment, the conductive ribs 3 include longitudinal connecting ribs 8 , and the longitudinal connecting ribs 8 are connected to transverse supporting ribs 11 . The transverse supporting ribs 11 are arranged along the length direction of the gap between the first heating plate 1 and the second heating plate 2 .

[0064] In this embodiment, three transverse supporting ribs 11 are provided, and the three transverse supporting ribs 11 are distributed in pairs at both ends of the first heating plate 1 and at both ends of the second heating plate 2 .

[0065] Since the first heating sheet 1 and the second heating sheet 2 need to be rolled into a C shape during use, the transverse support rib 11 is rolled into a C shape together with the heating sheet during use, which plays a role in supporting and increasing the strength of the heating sheet, thereby avoiding problems such as shrinkage holes caused by high temperature when the heating sheet is working. The transverse support rib 11 itself is not connected to the circuit, and its length can be changed appropriately, which will not cause adverse conditions such as short circuit of the heating sheet.

[0066] The working principle of this embodiment is the same as that of Embodiment 1 and will not be described again here.

[0067] Example 4

[0068] like Figure 6 As shown, the embodiment of the present application discloses a heating sheet structure of an atomizer core. The difference between this embodiment and embodiment 1 is that:

[0069] In this embodiment, the conductive ribs 3 include longitudinal connecting ribs 8, and three longitudinal connecting ribs 8 are provided. The longitudinal connecting ribs not only play the role of connecting the first heating plate 1 and the second heating plate 2 to conduct the circuit, but also play a longitudinal supporting role. When each heating plate is working, the supporting force of the longitudinal connecting ribs 8 is greater than the force of the liquid-conducting cotton 16 contracting after being heated, so as to prevent the liquid-conducting cotton 16 from contracting due to heat and causing the problem of hole blocking.

[0070] The working principle of this embodiment is similar to that of Embodiment 1 and will not be described again here.

[0071] Example 5

[0072] like Figure 7 As shown, the embodiment of the present application discloses a heating sheet structure of an atomizer core. The difference between this embodiment and embodiment 1 is that:

[0073] In this embodiment, the first conductive rib 3 includes a first longitudinal connecting rib 12, a second longitudinal connecting rib 13 and a transverse supporting rib 14. The first longitudinal connecting rib 12 is connected to the first heating sheet 1, the second longitudinal connecting rib 13 is connected to the second heating sheet 2 and is staggered with the first longitudinal connecting rib 12. The first longitudinal connecting rib 12 and the second longitudinal connecting rib 13 are connected by the transverse supporting rib 14. The three form an L shape.

[0074] By combining and connecting the longitudinal reinforcement and the transverse reinforcement, the longitudinal reinforcement can be extended to any heating area of ​​a single heating plate without affecting the normal operation of the heating plate. In addition, the connection method of the transverse reinforcement and the vertical reinforcement is adopted to support the blank part between the first heating plate 1 and the second heating plate 2, so that the structural strength of the heating plate is higher.

[0075] The working principle of this embodiment is the same as that of Embodiment 1 and will not be described again here.

[0076] Example 6

[0077] like Figure 8 and Fig. 9 As shown, an embodiment of the present application discloses an atomizer core. The atomizer core includes a fixed bracket 15, a liquid-conducting cotton 16 and a fixed plug 17, and also includes the heating plate structure in the above-mentioned embodiment 1. The fixed bracket 1 is a cylindrical structure, which is provided with a mounting hole 18. The liquid-conducting cotton 16 is located in the mounting hole 18. The heating plate structure is wound and sleeved in the liquid-conducting cotton 16, and fits with the liquid-conducting cotton 16. The fixed plug 17 is used to seal the liquid-conducting cotton 16 and the heating plate structure in the mounting hole 18. The first heating plate 1 and the second heating plate 2 are arranged at intervals along the axial direction of the mounting hole 18, and the first pin 4, the second pin 5, the third pin 6 and the fourth pin 7 pass through the fixed plug 17 and extend out of the fixed bracket 15.

[0078] In this embodiment, a vent hole 19 is formed on the fixed plug 17, and the vent hole 19 is connected with the mounting hole 18 to form an airflow channel 20, and the airflow channel 20 passes through the fixed bracket 15. The arrow k in the figure indicates the direction of the airflow, and the arrow j indicates the oil inlet route. The oil enters from the liquid guide cotton 16 and is heated and atomized. The side wall of the fixed bracket 15 is provided with a heat dissipation hole 24.

[0079] The implementation principle of the atomizer core of this embodiment is:

[0080] When in use, the outer sides of the first heating sheet 1 and the second heating sheet 2 are laid flat on the liquid-conducting cotton 16, rolled together into a C shape, and then placed in the mounting hole 18 of the fixed bracket 1. One end of the mounting hole 18 has a support platform for supporting the heating sheet and the liquid-conducting cotton 16, and then the mounting hole 18 is blocked with a fixing plug 17 to prevent the heating sheet and the liquid-conducting cotton 16 from detaching from the fixed bracket 15. The fixing plug 17 is provided with a through groove to facilitate the four pins to extend out of the mounting hole 18 and connect to the external circuit.

[0081] When any two pins are energized (such as the first pin 4 and the second pin 5), the heating plate structure generates heat, and the atomized oil on the liquid-conducting cotton 16 is heated to turn into gas, which is sucked into the mouth of the smoker for inhalation. By switching different pins, the heating plate can be heated alternately.

[0082] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
