Description

Technical Field

[0001] The present application relates to the technical field of atomization technology, and in particular to an atomization core, an atomization device, an electronic cigarette, and an assembly method thereof. Background Art

[0002] An electronic cigarette (also known as an "e-cigarette") is an electronic system that generates an aerosol from an atomized substrate for inhalation by the user. The aerosolized substrate can be a liquid (e.g., tobacco liquid), a solid (e.g., tobacco leaves), or a gel (e.g., tobacco paste).

[0003] The electronic cigarette includes an atomizing device and a power supply component for powering the device. The atomizing device includes an oil storage chamber for storing the atomizing matrix and an atomizing core for heating the atomizing matrix. Figure 12 The atomizer core 1 of the prior art includes an atomizer tube 101, a hollow ceramic body 104, and a heating element. The ceramic body 104 is disposed within the atomizer tube 101, and an oil inlet hole 103 is provided on the atomizer tube 101. The heating element is disposed on the inner wall of the ceramic body 104 corresponding to the hollow area. The outer wall of the ceramic body 104 is used to absorb the atomized matrix. The atomized matrix directly penetrates from the outer wall to the inner wall, and is heated by the heating element on the inner wall to produce smoke. The heating element is connected to the conductive electrode via a pin 102. When the oil pressure in the oil storage chamber in the atomizer device is too high, the atomized matrix easily penetrates from the outside and quickly penetrates to the other side, resulting in oil flying, oil leakage, and gurgling noises, affecting the user experience.

[0004] In addition, during the installation of the existing atomizer core, the heating element is pierced with pins and needs to be electrically connected to the conductive electrode through welding, etc., which makes the assembly process more complicated and requires manual work, resulting in low production efficiency and high production costs, leaving room for improvement.

The porous oil guiding body 10 includes at least one heating body 13 and at least one oil storage body 14. The heating body 13 is connected to the oil storage body 14. An oil storage space 143 for receiving the atomization matrix is formed in each oil storage body 14. The oil storage body 14 is provided with an oil passing area 144 for communicating the oil storage space 143 with the outside. The heating element 11 is provided on one side of each heating body 13. When in use, the atomization matrix stored in the oil storage body 2 enters the oil storage space 143 in the oil storage body 14 through the oil passing area 144. Since the oil storage body 14 is made of porous material, it can absorb the atomization matrix and transfer it to the heating body 13. The heating element 11 is used to heat the atomization matrix received by the heating body 13, thereby generating smoke for the user to inhale.

[0067] Referring to Figure 5 、 6 In some embodiments, the oil storage body 14 includes an enclosing wall 145 and a bottom wall 146. The enclosing wall 145 and the bottom wall 146 define the oil storage space 143. One end of the oil storage body 14 away from the bottom wall 146 is open, and the opening serves as the oil passing area 144. In other embodiments, the oil storage body 14 further includes a top wall, and a hole is opened on the top wall, and this hole serves as the oil passing area 144. The oil storage space 143 can be used to control the speed of receiving the atomization matrix, increase the oil supply area, and thus stably supply oil.

[0068] In some embodiments, the heating body 13 is in a sheet shape, stably receives the atomization matrix permeated from the oil storage body, and is convenient for forming an atomization space 15 with the oil storage body 14. In other embodiments, the heating body 13 can be set in other shapes as needed, including but not limited to a curved surface shape, a semi-columnar shape, etc.

[0069] In some embodiments, the heating body 13 is formed by extending from the outer side of the enclosing wall 145 of the oil storage body 14 in a direction away from the oil storage body 14.

[0070] Referring to Figure 5 、 6 , in some embodiments, the heating body 13 includes opposite first side surface 131 and second side surface 132. An atomization space 15 is formed between the first side surface 131 and the outer surface of the enclosing wall 145. The atomization space 15 is used for the smoke generated by the heating element 11 to heat the atomization matrix to flow. The heating element 11 is provided on the first side surface 131. In some examples, the second side surface 132 is smoothly and transitionally connected to the outer surface of the enclosing wall 145.

One heating body 13 can be provided between the two oil storage bodies 14 (such as Figure 8 ), or two can be provided (such as Figure 9 ). In some other embodiments, the number of the oil storage bodies 14 can be set to multiple according to needs (such as Figure 10 ), and the heating body 13 is connected between adjacent oil storage bodies 14.

[0072] In some embodiments, as shown in Figure 5 and Figure 6 , the oil storage body 14 includes a first oil storage body 141 and a second oil storage body 142. The first oil storage body 141 has a first opposite surface 1411 opposite to the second oil storage body 142, and the second oil storage body 142 has a second opposite surface 1421 opposite to the first oil storage body 141. An atomization space 15 is defined by enclosing the first opposite surface 1411, the second opposite surface 1421, and the first side surface 131 of the heating body 13 for the smoke generated by heating to pass through.

[0073] In some embodiments, the heating body 13 and the oil storage body 14 are integrally formed. The one-piece structure has fewer components and is convenient for assembly.

[0074] In some embodiments, the heating body 13 and the oil storage body 14 are respectively made of a hard porous oil guiding body 10; specifically, the heating body 13 and the oil storage body 14 are made of glass, ceramic, mica or quartz into a porous hard structure. In some other examples, it can also be an oil guiding cotton or oil guiding fiber with a fixed shape.

[0075] Among them, the heating element 11 is made of an electrically heatable metal, or made of graphene or carbon-containing nanomaterials. The heating element can be in the form of a wire, a mesh, etc. embedded on the porous oil guiding body, or can be printed on the porous oil guiding body with conductive ink, etc., and is not limited thereto.

[0076] In some embodiments, a first conductive electrode 147 and a second conductive electrode 148 are provided at one end of the porous oil guide body 10 away from the opening. The first conductive electrode 147 and the second conductive electrode 148 are exposed from the end face of the porous oil guide body 10, and the first conductive electrode 147 and the second conductive electrode 148 are electrically connected to the heating element 11 respectively. Specifically, the heating element 11 is connected to the first conductive electrode 147 and the second conductive electrode 148 through wires respectively. The wires, the heating element 11, the first conductive electrode 147 and the second conductive electrode 148 are integrally formed on the porous oil guide body 10, with high integration and convenient installation. The first conductive electrode 147 and the second conductive electrode 148 are made of conductive metal respectively, or made of graphene or carbon-containing nanomaterials.

[0077] The present application also provides an atomization device 100, which includes the above-mentioned atomization core 1 and an oil storage body 2. The atomization core 1 is installed in the oil storage body 2. An oil storage cavity 21 for storing an atomization matrix is defined in the oil storage body 2, and the oil storage space 143 of the oil storage body 14 communicates with the oil storage cavity 21.

[0078] As Figure 4 shown, in some embodiments, one end of the oil storage body 2 has a mouthpiece portion 22, and a smoking port 221 is formed in the mouthpiece portion 22. A smoke guide tube 23 extends towards the inside of the oil storage cavity 21 at the smoking port 221 of the oil storage body 2. The oil storage cavity 21 is formed between the outer wall of the smoke guide tube 23 and the inner wall of the oil storage body 2. A smoke guide channel 231 communicating with the smoking port 221 is formed in the smoke guide tube 23, and the smoke guide channel 231 communicates with the atomization space 15 of the atomization core 1. The smoke guide tube 23 is integrally formed on the oil storage body 2, reducing the assembly time.

[0079] As Figure 7 shown, in some embodiments, one end of the oil storage body 2 away from the mouthpiece portion 22 is open and sealed with a seal 3. The seal 3 is made of rubber, silica gel, plastic, latex, etc. An installation groove 31 is provided at one end of the seal 3 facing away from the oil storage cavity 21. The atomization core 1 is accommodated and installed in the installation groove 31. The groove wall of the seal 3 corresponding to the installation groove 31, the outer surface of the oil storage body 14, and the first side surface 131 of the heating element 13 jointly enclose and define the atomization space 15. The seal 3 not only plays a role in sealing the oil storage cavity 21, but also plays a role in fixing the atomization core 1. Compared with the traditional atomization device, the installation bracket for fixing the atomization core 1 is omitted, the number of parts is less, the production cost is reduced, and the assembly is more convenient and efficient. In some other examples, it may also be that the oil storage body 14 and the heating element 13 themselves enclose the atomization space 15.

[0080] In some embodiments, at least one oil through hole 32 is opened at one end of the sealing member 3 facing the oil storage chamber 21, and the oil through hole 32 is communicated with the oil storage chamber 21 and the oil storage space 143 respectively, and is used to connect the oil storage space 143 with the oil storage chamber 21. The oil in the oil storage chamber 21 enters the oil storage space 143 through the oil through hole 32 to supply oil to the oil storage body 14.

[0081] Reference Figure 4 and Figure 7 In some embodiments, the aperture of the end of the oil through hole 32 connected to the oil storage chamber 21 is larger than the aperture of the end of the oil through hole 32 connected to the oil storage space 143; further, the aperture of the oil through hole 32 gradually decreases from the end with a larger aperture to the end with a smaller aperture. The structure of gradually decreasing aperture reduces the area of the oil storage body 14 contacting the smoke oil, avoiding oil leakage caused by excessive oil supply, and also ensures that the atomized matrix in the oil storage chamber can still enter the oil storage space even when it is almost used up.

[0082] In some embodiments, the sealing member 3 is provided with a slot 33 corresponding to the smoke guide tube 23. The smoke guide tube 23 is inserted into the slot 33 for a fixed, sealed connection with the smoke guide tube 23. The bottom wall 146 of the groove of the sealing member 3 corresponding to the slot 33 is provided with a smoke hole 34. The smoke hole 34 is in communication with the smoke guide channel 231 and the atomization space 15, respectively. The smoke guide tube 23 is directly inserted into the slot 33 of the sealing member 3 without the need for an additional sealing structure, thus reducing the number of parts and saving production costs. During use, the smoke generated in the atomization space 15 passes through the smoke hole 34, the smoke guide channel 231, and the smoking port 221 in sequence for inhalation by the user.

[0083] In some embodiments, a base 4 is provided at one end of the sealing member 3 away from the oil storage chamber 21 . The base 4 is provided with an air inlet 41 . The air inlet 41 is communicated with the atomization space 15 of the atomizer core 1 .

The ends of the third conductive electrode 42 and the fourth conductive electrode 43 are exposed from opposite sides of the base 4. The third conductive electrode 42 and the fourth conductive electrode 43 are in contact with the first conductive electrode 147 and the second conductive electrode 148, respectively. This contact connection eliminates the need for wires during assembly, facilitating assembly. The third conductive electrode 42 and the fourth conductive electrode 43 are each made of a conductive metal, or graphene, or a carbon-containing nanomaterial.

[0085] In some embodiments, an oil absorption cotton 5 is provided between the atomization core 1 and the base 4 to prevent the atomization core 1 from leaking oil and contaminating the electronic components on the power supply assembly 200. The oil storage body 2, the seal 3, the atomization core 1, and the base 4 are detachably connected to each other; specifically, referring to Figure 5 and Figure 4 , one end of the atomization core 1 having an oil passage area 144 is inserted into the installation groove 31 on the seal 3 towards the seal 3, referring to Figure 4 , an insertion groove adapted to the seal 3 is provided on the inner wall of the oil storage body 2, a card slot is provided at one end of the insertion groove away from the smoking port 221, the seal 3 is inserted and arranged in the insertion groove, and one end of the base 4 is inserted and arranged in the insertion groove and is engaged with the card slot through a buckle.

The power supply assembly 200 and the atomization device 100 are detachably connected. The power supply assembly 200 includes a battery cell, a fifth conductive electrode, and a sixth conductive electrode. The fifth conductive electrode and the sixth conductive electrode are electrically connected to two electrodes of the battery cell respectively. In some examples, the fifth conductive electrode and the sixth conductive electrode are respectively in contact with the third conductive electrode 42 and the fourth conductive electrode 43 of the above-mentioned atomization device 100. In other examples, if no base is installed on the atomization device, the fifth conductive electrode and the sixth conductive electrode can be respectively in contact with the first conductive electrode 147 and the second conductive electrode 148 of the atomization core 1, and the contact type electrode assembly is more convenient and fast.
