[0002] Electronic cigarettes are electronic products that imitate cigarettes, mainly composed of a smoke tube, atomizer core, circuit board, battery and other components. The atomizer core is the core device for generating smoke, which heats the smoke oil through the heat it emits to achieve the effect of atomizing the smoke oil. Among them, the electronic cigarette atomizer core includes a core rod, oil-absorbing cotton, a heating net and a heating net wire that energizes the heating net. The heating net is wrapped around the outer wall of the core rod, and the oil-absorbing cotton is wrapped around the heating element. The heating net heats the external oil-absorbing cotton to generate smoke.

[0003] In the related art, the heating net is in the shape of an enclosing structure and is attached to the outer wall of the core rod. Since the heating element of the heating net has a limited area, the area of ​​the oil-absorbing cotton blanket that is heated is also limited, which results in a small amount of smoke and a poor experience. Moreover, as the core component of the atomizer core, the heating net has a small structure of each connecting part of the mesh structure, which is easy to burn out and malfunction. Once the heating net has a problem, the entire atomizer core will not be able to produce smoke, and the electronic cigarette will not be able to be used normally.

[0026] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0029] In addition, the descriptions of "first", "second", etc. in the present utility model are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0030] Please refer to the attached Figure 1The utility model provides a multi-piece heating structure. The multi-piece heating structure 10 includes a plurality of heating elements 1 wrapped around the outer periphery of a core rod in a full circle, a positive lead 3 and a plurality of negative leads 5. The plurality of heating elements 1 are spaced apart along the axis of the core rod, one end of the plurality of heating elements 1 is simultaneously connected to the positive lead 3, and the other end is respectively connected to different negative leads 5 to form a parallel connection. The multi-piece heating structure increases the heating area by arranging a plurality of the heating elements 1 along the axis of the core rod, thereby increasing the heating amount and doubling the amount of smoke to meet the user's demand for a large amount of smoke. By connecting the heating elements 1 in parallel, the plurality of heating elements 1 can heat up simultaneously or individually. When one heating element 1 fails, the other heating element 1 can continue to work to ensure the normal operation of the atomization core, and further ensure the normal use of the electronic cigarette. In this way, the problem of increased failure rate due to the arrangement of multiple heating elements 1 is solved. The parallel connection of the heating elements 1 enables multiple heating at the same time. If one or two of them fail, as long as the other heating elements 1 can continue to heat up, the atomization core can work normally and the electronic cigarette can be used normally, which greatly reduces the failure rate of the atomization core and further reduces the phenomenon that the electronic cigarette cannot be used normally.

[0031] Furthermore, the number of the heating elements 1 is at least two and spaced apart. Specifically, the number of the heating elements 1 can be two, three or more. Figure 1 As shown, the heating element 1 is two connected in parallel, such as Figure 2 As shown, there are three heating elements 1 connected in parallel, one heating element 1 is wrapped around the outer periphery of the core rod in a full circle of 360°, and two or three heating elements 1 are distributed side by side from top to bottom. As the number of heating elements 1 increases, the heating area increases, and thus the amount of smoke increases, which can meet the demand for large smoke volume of electronic cigarettes.

[0032] The heating element 1 can be a ring-shaped whole, or it can be divided into a plurality of half-rings. Figure 3 and Figure 4 As shown, each of the heating elements 1 is divided into two parts, each of which is a half circle, forming a half-circle heating element, and combined to form a full-circle heating element. One end of each of the divided half-circle heating elements 11 is connected to the positive lead 3, and the other end of the half-circle heating element 11 is connected to one of the negative lead 5. Figure 3 As shown, the heating elements A1, A2 and A3 in part A are connected in parallel, the heating elements B1, B2 and B3 in part B are connected in parallel, and parts A and B are connected in series, forming a heating technology that alternates between series and parallel. Multiple half-circle heating elements generate heat in tandem, and multiple heating elements 1 are heated together or alternately by energizing different electrode leads. Similarly, Figure 4The scheme shown also achieves the above-mentioned effect. This method realizes interactive heating atomization, and while achieving a large amount of smoke, even if one or more heating elements fail, the electronic cigarette can still be used normally, which greatly extends the use time of the electronic cigarette and solves the problem in the prior art that a problem with one heating element 1 causes the entire electronic cigarette to be unusable.

[0033] In this embodiment, the width of one heating element 1 is 6 mm, and the length can be adjusted according to the circumference of the core rod. The spacing between two adjacent heating elements 1 is 1-2 mm. Figure 1 As shown, three heating elements 1 are arranged side by side with a total width of 22 mm.

[0034] It is worth explaining that when the heating element 1 is divided into two half-circles, the structures of the two half-circles 11 are the same. That is, the two half-circles 11 are both semicircular, so that the positive lead 33 and the negative lead 55 are located on the 180° center line of the core rod, making each structure more stable and having high strength against external tension. This solves the problem in the prior art that the heating network is deformed or separated from the oil-conducting cotton due to the abnormal angle caused by the pulling of the lead, which then causes a short circuit or dry burning and produces an odor, affecting the taste. Of course, it should be noted that in other embodiments, the structures of the two half-circle heating elements 11 may also be different. It may be a mode in which one half-circle is large and the other half-circle is small, as long as the two half-circles can form a full circle.

[0035] The multi-piece heating structure also includes a connecting piece 6, and the heating element 1 is connected to the negative lead 5 and / or the positive lead 3 via the connecting piece 6. That is to say, the heating element 1 is connected to the negative lead 5 or the positive lead 3 via the connecting piece 6, or the heating element 1 is connected to both the positive lead 3 and the negative lead 5 via the connecting piece 6. Preferably, in the present embodiment, the heating element 1 is connected to the negative lead 5 via the connecting piece 6. The function of the connecting piece 6 is to strengthen the connection strength between the heating element 1 and the lead, prevent the heating element 1 from being separated from the lead, thereby reducing the failure rate, and solving the problem in the prior art that the heating element is directly welded to the lead and is prone to separation.

[0036] Specifically, the connecting piece 6 is welded to the negative electrode lead 5. The connecting piece 6 is a stainless steel sheet, and the cross section of the connecting piece 6 is arc-shaped, which matches the curvature of the core rod, so that it can fit the surface of the core rod during installation, so as to achieve an assembly effect.

[0037] In one embodiment, the three negative electrode leads 55 are connected as one and connected to the same negative electrode. Specifically, one positive electrode lead 33 is connected to the positive electrode B+ of the circuit board of the electronic cigarette, and the three negative electrode leads 55 are connected to the negative electrode B- of the circuit board. The two half-circle heating elements 11 of each heating element are heated at the same time, forming a full-circle surrounding heating to improve the heating efficiency.

[0038] Please note that Figure 5 , the three negative electrode leads 5 are connected to different negative electrodes respectively. Specifically, one positive electrode lead 3 is connected to the positive electrode B+ of the circuit board 7 of the electronic cigarette, and the six negative electrode leads 5 are respectively connected to the negative electrodes B-1, B-2, B-3, B-4, B-5 ​​and B-6 of the circuit board 7. The six half-circle heating elements 11 can be independently controlled to be energized, that is, only two or three of the half-circle heating elements 11 can be energized for heating, thereby supporting interactive heating technology. Since the heating sheet in the prior art will have carbon accumulation on the surface after being used for a period of time, which affects the taste, through the interactive heating technology, the carbon accumulation time of the heating element 1 is delayed by more than twice, maintaining the taste and extending the service life.

[0039] Furthermore, in the present embodiment, the heating element 1 is in a sheet-like structure or a mesh-like structure. Preferably, in the present embodiment, the heating element 1 is in a mesh-like structure. Preferably, the heating element 1 is a thin mesh sheet.

[0040] Specifically, in this embodiment, the heating element 1 is a stainless steel heating net, which has good electrical conductivity, good positioning effect, and is not easy to deform.

[0041] Please see attached Figure 5 and 6 The utility model also provides an electronic cigarette atomizer. The electronic cigarette atomizer comprises the multi-piece heating structure 10, a core rod 40, oil-conducting cotton 50, a bracket 60 and a fixing seat 70, the heating element 1 is attached to the outer periphery of the core rod 40, the oil-conducting cotton 50 is axially assembled on the core rod 40 and is located outside the heating element 1, the core rod 40 and the oil-conducting cotton 50 are axially assembled in the bracket 60, and the fixing seat 70 is fixed to the end of the bracket 60.

[0042] Specifically, in this embodiment, the bracket 60 is made of steel, which has good structural stability and long service life.

[0043] Specifically, in this embodiment, the fixing seat 70 is a silicone fixing seat or a plastic fixing seat. Preferably, the fixing seat 70 is a plastic fixing seat. The fixing seat made of plastic has a certain elastic deformation, and through its deformation characteristics, it is interference-fitted in the atomizer bracket to achieve a stop effect.

[0044] The multi-piece heating structure and the electronic cigarette atomizer provided by the utility model increase the heating area by arranging a plurality of the heating elements along the axis of the core rod, thereby increasing the heating amount and doubling the amount of smoke to meet the user's demand for a large amount of smoke. By connecting the heating elements in parallel, the plurality of heating elements can heat simultaneously or individually. When one heating element fails, the other heating element can continue to work, thereby ensuring the normal operation of the atomization core and further ensuring the normal use of the electronic cigarette.
