Description

Technical Field

[0001] The utility model relates to the technical field of atomization devices, and more specifically, to an atomization core, an atomizer and an electronic cigarette. Background Art

[0002] An electronic cigarette is an electronic product that imitates traditional cigarettes, and its function is to heat and atomize e-liquid through an internal atomizer for smokers to use. Currently, the components of an electronic cigarette usually include an air flow detector, a control circuit, an e-liquid bottle, an atomization core and a power supply module. When the user inhales, a high-speed air flow is generated. After the air flow detector senses it, the control circuit is awakened. After calculation and measurement, the control circuit controls the output power of the atomization core according to the magnitude of the oral suction force, and then controls the atomization amount of the e-liquid. The generated smoke is dispersed into an aerosol form with the inhaled air flow for the user to inhale. Compared with the direct combustion of traditional tobacco, it can effectively reduce the generation of harmful substances and weaken the harm to smokers and the people around them to a certain extent.

[0035] To solve the related technical problems, as Figure 1 and Figure 2 shown, an atomization core provided by an embodiment of the present utility model includes:

[0036] A core body 1, an atomization cavity 103 is arranged in the core body 1, an air outlet 11 is arranged at the upper part of the core body 1, an air inlet 8 is arranged at the lower part of the core body 1, the air inlet 8 is located on the annular side of the core body 1, the air outlet 11, the air inlet 8 are communicated with the atomization cavity 103, and an oil inlet hole 2 is also arranged on the core body 1;

[0037] A guide oil cotton 4, which is arranged in the atomization cavity 103 and corresponds to the oil inlet hole 2;

[0038] The heating element 5 is disposed inside the atomization chamber 103 and on the inner side of the oil guiding cotton 4;

[0039] The first seal 7 is disposed at the lower part of the core body 1 and above the air inlet 8, and is used to form a seal between the atomization core and the atomizer;

[0040] The second seal 10 is disposed at the lower part of the core body 1 and below the air inlet 8, and is used to form a seal between the core body 1 and the atomizer.

[0041] In this embodiment, the structure of the core of the electronic cigarette is an atomizer. An atomization core is arranged inside the atomizer. The e-liquid in the atomizer can enter the atomization core and is atomized under the action of the heating element 5 in the atomization core. The atomized e-liquid is discharged from the atomization core along with the airflow. For the atomization core, it at least includes a core body 1, an oil guiding cotton 4 and a heating element 5. The core body 1 is a hollow tubular structure, and the hollow area serves as the atomization chamber 103. The oil guiding cotton 4 can be installed inside the atomization chamber 103, and the heating element 5 can also be installed inside the atomization chamber 103 and on the inner side of the oil guiding cotton 4. An air outlet 11, an oil inlet hole 2 and an air inlet 8 communicating with the atomization chamber 103 are formed on the core body 1. The e-liquid in the atomizer enters the atomization chamber 103 through the oil inlet hole 2 and is inhaled by the oil guiding cotton 4, and is heated and atomized after contacting the heating element 5. External airflow enters the atomization chamber 103 from the air inlet 8 and is discharged from the air outlet 11 along with the atomized e-liquid.

[0042] In this embodiment, the oil inlet hole 2 on the core body 1 is above the air inlet 8. After the core body 1 is installed in the atomizer, the oil inlet hole 2 corresponds to the oil storage chamber in the atomizer. To prevent the e-liquid from entering the air inlet 8, a first seal 7 is provided on the core body 1 in this embodiment. The first seal 7 is located at a position between the oil inlet hole 2 and the air inlet 8 and is relatively close to the air inlet 8. After the core body 1 is installed in the atomizer, a seal is formed between the first seal 7 and the atomizer, thereby preventing the e-liquid in the oil storage chamber from entering the air inlet 8.

[0043] In one implementation of the first seal 7, the first seal 7 can be a flexible sealing ring, and the seal is achieved through the deformation of the flexible sealing ring. In another implementation of the first seal 7, the first seal 7 can be a rigid sealing ring, and the seal is achieved through the close contact of the rigid sealing ring. In this embodiment, no specific limitation is imposed on the specific structure of the first seal 7.

[0044] On the basis of the above-described embodiments, when the core body 1 is applied to a structure that can be separately disassembled and replaced from the atomizer, in order to avoid leakage of e-liquid from the connection between the atomizer and the core body 1 due to movable connection. In this embodiment, a second seal 10 is further provided on the core body 1, and the second seal 10 is located below the air inlet 8. After the core body 1 is installed in the atomizer, a seal is formed between the second seal 10 and the atomizer, thereby preventing the e-liquid in the oil storage chamber from leaking. For the specific implementation of the second seal 10, reference can be made to the description of the first seal 7 above, and this embodiment will not be elaborated here.

[0045] The utility model achieves the purpose of forming at least two-stage seals between the atomization core and the atomizer, and forming seals above and below the air inlet 8 respectively, thereby realizing the technical effect of enhancing the sealing performance between the core body 1 and the atomizer, and being able to effectively prevent e-liquid from entering the air inlet 8 and leaking out of the atomizer, and further solving the problem that the e-liquid in the atomizer in the related art is prone to leak from the connection part between the atomization core and the atomizer, and the leaked e-liquid is prone to enter the air inlet 8 of the atomization core and leak out of the atomizer.

[0046] In an embodiment of the first seal 7 and the second seal 10, the first seal 7 is a first sealing ring sleeved on the core body 1, and the second seal 10 is a second sealing ring sleeved on the core body 1.

[0047] Specifically, in this embodiment, the edge of the first sealing ring protrudes from the surface of the core body 1, so as to form a seal with the atomizer after installation. Similarly, the edge of the second sealing ring also protrudes from the surface of the core body 1.

[0048] Since the first sealing ring is located above the air inlet 8, it not only prevents e-liquid from entering the air inlet 8, but also prevents e-liquid from leaking out of the atomizer. Therefore, the first sealing ring needs to have strong sealing performance. To achieve this purpose, as Figure 1 shown, in this embodiment, the first sealing ring includes a sealing ring body 71 and a plurality of annular protrusions 72 provided on the sealing ring body 71. The plurality of annular protrusions 72 are spaced apart along the axial direction of the sealing ring body 71, and the end of the annular protrusion 72 away from the sealing ring body 71 is provided with a planar sealing surface.

[0049] Specifically, in this embodiment, the plurality of annular protrusions 72 form multi-stage seals, thereby improving the sealing performance between the first sealing ring and the atomizer, being able to effectively prevent e-liquid from entering the air inlet 8, and increasing the friction between the core body 1 and the atomizer, and being able to prevent the core body 1 from falling off after installation. On this basis, to further increase the friction and sealing performance, the edge surface of the annular protrusion 72 in this embodiment is a planar sealing surface. Further, for the convenience of installing the core body 1, the cross-section of the annular protrusion 72 in this embodiment is set to be trapezoidal.

[0050] In an embodiment of the core body 1, as Figure 1 and Figure 2 shown, the core body 1 includes a first tube body 101 and a second tube body 102. The upper part of the second tube body 102 is sleeved inside the first tube body 101, and the oil guiding cotton 4 is sleeved on the upper part of the second tube body 102 and is located between the first tube body 101 and the second tube body 102;

[0051] An air outlet 11 is provided at the upper end of the first tube body 101, an oil inlet hole 2 is provided on the first tube body 101, an oil passing hole 3 is provided on the upper part of the second tube body 102, the oil passing hole 3 corresponds to the oil inlet hole 2, a heating element 5 is arranged inside the second tube body 102, and an air inlet 8 is provided at the lower part of the second tube body 102;

[0052] A first seal 7 and a second seal 10 are both arranged on the second tube body 102.

[0053] Specifically, in this embodiment, the core body 1 mainly includes two mutually sleeved tube bodies, namely the first tube body 101 and the second tube body 102. Both the upper and lower ends of the first tube body 101 are of an open structure, and at least the upper end of the second tube body 102 is of an open structure. The upper end of the second tube body 102 is sleeved and fixed inside the first tube body 101, and the oil guiding cotton 4 is located in the sandwich layer between the first tube body 101 and the second tube body 102. The oil guiding cotton 4 can be fixed through the second tube body 102, and the e-liquid enters the oil guiding cotton 4 through the oil inlet hole 2 on the first tube body 101. The heating element 5 is fixed inside the second tube body 102, and the second tube body 102 can also serve as a fixing structure for the heating element 5. In order to enable the e-liquid to contact the heating element 5 through the oil guiding cotton 4, an oil passing hole 3 is provided on the second tube body 102 in this embodiment. The e-liquid contacts the heating element 5 after passing through the oil guiding cotton 4 and the oil passing hole 3 in sequence, and thus is atomized.

[0054] In an embodiment of the air inlet 8, as Figure 1 and Figure 2 shown, the air inlet 8 is set to a circumferentially closed structure, and a plurality of air inlets 8 are provided and evenly distributed along the circumference of the second tube body 102, so as to facilitate the processing of the air inlet 8 and increase the air intake;

[0055] In an embodiment of the oil inlet hole 2, the oil inlet hole 2 is set to a circumferentially closed structure, and a plurality of oil inlet holes 2 are provided and evenly distributed along the circumference of the first tube body 101, so as to facilitate the processing of the oil inlet hole 2 and increase the oil intake.

[0056] As Figure 1As shown, in one embodiment of the heating element 5, the heating element 5 has a tubular structure, and the tubular heating element 5 is sleeved and fixed inside the second tube body 102. In this embodiment, to prevent the heating element 5 from moving axially, the atomization core in this embodiment further includes a fixing seat 6. The fixing seat 6 is arranged inside the second tube body 102. The upper end of the fixing seat 6 abuts against the lower end of the heating element 5, and the circumferential side of the fixing seat 6 abuts against the inner wall of the second tube body 102.

[0057] Specifically, in this embodiment, the fixing seat 6 supports the heating element 5. The fixing seat 6 is generally in a ring structure and can be inserted into the second tube body 102 and fixed through a certain amount of elastic deformation. The upper end of the fixing seat 6 can abut against the lower end of the heating element 5, thereby supporting the heating element 5 and preventing the heating element 5 from moving downward. In this embodiment, the fixing seat 6 can be a rubber ring with a certain thickness.

[0058] Since the heating element 5 needs to be energized and intake air for heating, it needs to be connected to the electrode through a wire. The electrode is generally arranged at the lower end of the core body 1, that is, there is a fixing seat 6 between the electrode and the heating element 5. Therefore, for the convenience of wire connection, in this embodiment, a plurality of wire grooves are arranged on the circumferential side of the fixing seat 6. The wire grooves are arranged as through grooves penetrating axially. After the upper end of the wire is connected to the heating element 5, the lower end can pass through the wire grooves and then be connected to the electrode.

[0059] For the convenience of detaching the core body 1 from the atomizer, as Figure 1 and Figure 2 shown, in this embodiment, a circumferential edge portion 9 protruding radially is arranged at the lower end of the second tube body 102, and a notch 91 for detaching the atomization core is arranged on one side of the circumferential edge portion 9.

[0060] Specifically, in this embodiment, an installation groove for installing the core body 1 can be opened on the atomizer, and the installation groove is a countersunk head groove. The circumferential edge portion 9 on the core body 1 can abut against the head of the countersunk head groove, thereby positioning the position of the core body 1. Since a notch 91 is arranged on one side of the circumferential edge portion 9, the circumferential edge portion 9 presents a non-integral ring structure, while the head of the countersunk head groove is a complete circle. Therefore, a snap groove is formed between the notch 91 of the circumferential edge portion 9 and the countersunk head groove, and the core body 1 can be removed through this snap groove during disassembly.

[0061] According to another aspect of the present invention, an atomizer is provided, including the above-mentioned atomization core.

[0062] According to another aspect of the present invention, an electronic cigarette is provided, including the above-mentioned atomization core.
