Description

Technical Field

[0001] This invention relates to the field of electronic atomization technology, and in particular to an electronic atomization component that is easy to assemble and does not easily leak, and its manufacturing method. Background Technology

[0002] Electronic atomization technology uses electrical heating to bring a liquid to its boiling point, producing atomized vapor. Currently, it's widely used in the e-cigarette industry. With the innovative development of atomization technology, it's also being applied to other fields, such as beauty and medicine. The core of atomization technology lies in the electronic atomization component, which mainly consists of a heating element and a liquid guide. Based on the material of the liquid guide, it's mainly divided into hard liquid guide materials like porous ceramics and soft liquid guide materials like cotton cloth. Hard liquid guide materials are used in electronic atomization components, where the heating element and liquid guide material are well integrated, and the porous material provides support for the heating element. This makes them easy to assemble. However, their fixed porous structure shape and size hinder the passage of many large molecules in the e-liquid, and it's difficult to achieve a balance between liquid supply and retention, easily leading to leakage problems. Soft liquid-conducting materials, such as soft liquid-conducting cotton, have good liquid permeability and good liquid-locking ability, making them less prone to leakage. However, due to the poor structural strength of the heating element, they are easily deformed. Combined with the soft liquid-conducting material, assembly is difficult, and mass production requires a lot of manual labor. Therefore, there is a need for a structure and production process that is not prone to leakage, has a stable structure that is not easily deformed, and is convenient for mass production, so that it can be applied on a large scale.

The base 1 has a groove 12 that matches the liquid guide 3. The heating element 4 is a conductive metal component and includes a fixing part 43, a heating part 41 that connects to the fixing part 43 and heats up when energized, and a component connecting to the heating part 41. The electrode part 42, the base 1 is an injection molded part, the base 1 is fixed together with the heating element 4 by in-mold injection molding, the heating element 4 is provided at the bottom of the groove 12, the fixing part 43 is fixed in the base 1, the heating part 41 is exposed in the groove 12, the liquid guide 3 is soft and is provided in the groove 12 to position the liquid guide 3, the liquid guide 3 contacts the heating part 41, the cover 2 covers the groove 12 and connects to the base 1 to press the liquid guide 3, the base 1 and the cover 2 are hard to support the liquid guide 3 well;

An electrical connector 5 is provided on the base 1 and electrically connected to the electrode part 42 of the heating element 4. The base 1 is provided with a vent 13 that connects to the outside and passes through the heating part 41 of the heating element 4. The airflow of the vent 13 carries the atomized liquid generated by the heating element 4 to the outside of the electronic atomization assembly.

[0064] The electronic atomizing component of the present invention, which is easy to assemble and not prone to leakage, has at least the following beneficial technical effects: the electronic atomizing component uses a soft liquid guide 3, which has good liquid permeability, good liquid locking ability, and is not prone to leakage. Moreover, the substrate 1 and the heating element 4 are fixed together by in-mold injection molding, which gives the heating element 4 strength and makes it not easy to deform. The soft liquid guide 3 is placed in the groove 12 of the substrate 1 and fixed by the cover 2, which makes the structure stable and easy to manufacture in large-scale automated production.

[0065] Among them, the liquid-conducting material 3 can be a porous material. The so-called porous material can also be called a microporous material, which has many micropores distributed in it to realize the absorption and conduction of liquid. Hard porous materials are porous ceramic bodies, and soft porous materials are liquid-conducting cotton.

[0066] The substrate 1 has a groove 12 for accommodating and positioning the conductive liquid 3, a fixing part 43 for fixing the heating element 4, and an electrode part 42 for the flow of current. When the electronic atomizing assembly is in operation, external liquid comes into contact with the conductive liquid 3 through the inlet hole 22. The conductive liquid 3 conducts the contacted liquid to the heating part 41 of the heating element 4. The electrical connector 5 is electrically connected to an external circuit. Current flows through the heating element 4, which heats and atomizes the liquid to produce a mist. The mist is carried out of the electronic atomizing assembly by the airflow through the ventilation channel 13.

[0067] Preferably, the depth direction of the groove 12 is along the first direction 71, and the groove 12 is open on both sides in the second direction 72. The cover 2 is disposed on one side of the substrate 1 in the first direction 71, and the liquid guide 3 is located on both sides of the open sides of the groove 12 in the second direction 72. The first direction 71 is perpendicular to the second direction 72. In this way, during the manufacturing process, the liquid guide 3 can be simultaneously disposed in the grooves 12 of multiple substrates 1 along the second direction 72, and then the liquid guide 3 can be cut at the position between each substrate 1 to form a separate electronic atomization component.

[0068] Preferably, the liquid guide 3 is a single-layer structure with a certain thickness; or the liquid guide 3 is sheet-like, and the liquid guide 3 is a structure of at least two layers superimposed along the depth direction of the groove 12, which can be made of soft fibrous woven fabric or cotton-like liquid guide material.

[0069] The cover 2 is stacked on the liquid guide 3 along the depth direction of the groove 12. The at least two-layer stacked structure of the liquid guide 3 and the stacking arrangement of the cover 2 facilitate automated mass production.

[0070] Preferably, the cover 2 is fixed to the base 1 by ultrasonic welding.

[0071] Preferably, the base 1 is provided with a first positioning part 11, and the cover 2 is provided with a second positioning part 21 that cooperates with the first positioning part 11. The first positioning part 11 and the second positioning part 21 are in concave-convex cooperation to realize the positioning of the cover 2; and the cover 2 is embedded in the base 1 so that the surface of the cover 2 is as flush as possible with the surface of the base 1.

[0072] In some embodiments, see Figure 9-10 Both the cover 2 and the base 1 are made of plastic. The contact area between the cover 2 and the base 1 is provided with multiple protruding linear ultrasonic welding parts 23 for ultrasonic welding. During assembly, the ultrasonic waves cause the ultrasonic welding parts 23 to melt, deform, and then solidify, thereby fixing the cover 2 to the base 1; or in other embodiments, see... Figure 11-12 The base 1 is made of plastic, and the cover 2 is made of metal. The first positioning part 11 is protruding, and the second positioning part 21 is perforated. After the first positioning part 11 passes through the second positioning part 21, it is melted and deformed by ultrasonic welding to lock the second positioning part 21 and fix the cover 2.

[0073] Preferably, the liquid inlet hole 22 is provided on the cover body 2 and penetrates the cover body 2 along the thickness direction of the cover body 2.

[0074] Preferably, the vent 13 is located below the groove 12 and opens at the bottom of the groove 12. The fixing part 43 of the heating element 4 is located around the heating part 41 and is fixed to the base 1 around the opening of the vent 13 at the bottom of the groove 12. The heating part 41 is located in the opening of the vent 13 at the bottom of the groove 12, and the liquid guide 3 is located above the heating part 41, so that the heating part 41 is exposed in the groove 12 and the upper side of the heating part 41 is in contact with the liquid guide 3. The heating part 41 is provided with a gap 44. The heating part 41 includes heating circuits, and the gap 44 is formed between the heating circuits. The atomized gas generated by the heating part 41 enters the vent 13 through the gap 44 and then enters the vent 13.

[0075] Preferably, the heating element 4 is planar. Specifically, the bottom surface of the groove 12 is planar, the heating part 41 of the heating element 4 is flat and is arranged parallel to the bottom surface of the groove 12, and the lower side of the liquid guide 3 that contacts the heating part 41 is also planar; or the bottom surface of the groove 12 is curved, the heating part 41 is curved corresponding to the bottom surface of the groove 12, and the lower side of the liquid guide 3 that contacts the heating part 41 is also curved corresponding to the heating part 41.

[0076] Preferably, the heating element 41 includes multiple parallel first heating lines 411 and multiple second heating lines 412. The first heating lines 411 are parallel to the third direction 73. Each second heating line 412 is connected between two first heating lines 411. Multiple fixing parts 43 are located at both ends of each first heating line 411 and are fixed to the base 1. This effectively fixes both ends of each first heating line 411, giving it sufficient strength to prevent deformation under stress during the assembly of the electronic atomizing component and the liquid guide 3. The fixing parts 43 surround the second heating lines 412. The second heating lines 412 effectively interrupt the circuit; current flows through the electrode part 42, the first heating lines 411, and the second heating lines 412, but not through the fixing parts 43. Therefore, the fixing parts 43 do not generate heat. The fixing part 43 is bent relative to the heating part 41, and can be bent at 90 degrees. When the heating part 41 is unfolded, the fixing part 43 and the first heating line 411 are on the same straight line. Each fixing part 43 includes a first part 431 extending outward from the heating part 41 and a second part 432 protruding relative to the first part 431. This structure of the fixing part 43 can enhance the bonding strength with the substrate 1.

[0077] Preferably, the outer side of the substrate 1 has a straight, deep electrical connector hole 14, in which the electrode portion 42 of the heating element 4 is located. The electrical connector 5 is rod-shaped and can be a pin. It is inserted into the electrical connector hole 14, pressed tightly, and contacts the electrode portion 42 to achieve electrical connection. With the electrical connector 5, it is unnecessary to solder additional pins to the electronic atomization component for connection with external circuits, and the size and specifications are more standardized and modular.

[0078] Preferably, the electrical connector hole 14 extends to the lower side of the groove 12 and is open to the groove 12. The electrode part 42 is bent relative to the heating part 41, and can be bent at 90 degrees, extending into the electrical connector hole 14 to facilitate contact with the electrical connector 5. Specifically, there are two electrode parts 42, respectively located on both sides of the heating part 41 and bent to the same side. There are also two electrical connector holes 14 and two electrical connectors 5, located below the heating element 4 and on both sides of the vent 13. The two electrode parts 42 are located in the two electrical connector holes 14, and the two electrical connectors 5 are respectively inserted into the two electrical connectors 14, contacting the two electrode parts 42. A portion of the electrical connector 5 protrudes from the base 1 for connection to an external circuit. One electrical connector 5 and electrode are used for current inflow, and the other electrical connector 5 and electrode are used for current outflow. Furthermore, the two electrical connector holes 14 are located on the same side of the base 1 to facilitate connection to an external circuit.

[0079] In summary, the electronic atomizing component of this invention, which is easy to assemble and less prone to leakage, has a stable structure and is easy to manufacture in large-scale automated production.
