Background Art

In the field of electronic atomizer atomization technology, cotton core atomization technology is widely used in disposable electronic atomizer products. Cotton core atomization usually uses integrated oil storage cotton, oil guide cotton and heating wire/heating net to perform heating atomization. Because the heating wire/heating net is in direct contact with the oil storage cotton and oil guide cotton, and the oil storage cotton and oil guide cotton are mainly made of chemical fiber and organic cotton materials such as PA and PET, they are usually not resistant to high temperatures.

In the cotton core production process, affected by the material characteristics, the cotton core assembly process is more complicated, the assembly consistency is poor, and it is easy to cause product taste inconsistency.

In cartridge-changing electronic atomizer products, ceramic core atomization technology is widely used. Compared with cotton core atomizer devices, the manufacturing and assembly process of ceramic core devices is more stable and the batch production consistency is better. However, the existing ceramic cores are usually in direct contact with the atomization matrix, which is prone to oil leakage.

DETAILED DESCRIPTION

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

Reference herein to "embodiment" means that a particular feature, structure, or characteristic described in conjunction with the embodiment may be included in at least one embodiment of the present application. The occurrence of this phrase does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

The present application provides an atomization module, which includes an oil storage component and an atomization component.

In a specific embodiment, the atomizer assembly is the atomizer assembly 100 shown in Figures 1 to 7, and the atomizer assembly 100 includes an atomizer body 110 and a heating electrode 120. The atomizer body 110 is used to contact the oil storage assembly and can absorb the atomized matrix from the oil storage assembly. The atomizer body 110 has a first end surface 111, and the heating electrode 120 is arranged on the first end surface 111. The atomizer body 110 is formed with an oil guide groove 113 that is recessed compared to the first end surface 111. The oil guide groove 113 includes a pointed end 117, and the end of the pointed end 117 is closer to the heating electrode 120 than other parts of the oil guide groove 113.

Since a recessed oil guide groove 113 is provided on the first end face 111 of the atomization assembly 100, the pointed end 117 of the oil guide groove 113 can generate obvious capillary adsorption force, adsorbing the atomized matrix of the oil guide groove 113 to the pointed end 117, and the pointed end 117 guides the atomized matrix to the periphery of the heating electrode 120, thereby improving the atomization efficiency and reducing energy loss.

The atomizing body 110 can usually be made of porous ceramics prepared by sintering materials such as aluminum oxide and silicon oxide. The porosity of the ceramics is usually >50%. Of course, it is not limited to porous ceramics, and other porous materials can also be used.

Please refer to Figures 3, 4 and 5a. In some embodiments, the pointed end 117 includes a first side surface 118 and a second side surface 119 that intersect to form the pointed end 117. The first side surface 118 and the second side surface 119 are planes, that is, the orthographic projections of the first side surface 118 and the second side surface 119 on the reference plane where the first end surface 111 is located are both straight lines, and the angle between the two straight lines is an acute angle.

5b and 5c, in some other embodiments, the first side surface 118 and the second side surface 119 forming the pointed end 117 are both curved surfaces, that is, the orthographic projections of the first side surface 118 and the second side surface 119 on the reference plane where the first end surface 111 is located are both curves.

In some other embodiments, the orthographic projections of the first side surface 118 and the second side surface 119 forming the pointed end 117 on the reference plane where the first end surface 111 is located may be a combination of straight lines and curves.

It should be understood that the shape of the pointed end 117 is not limited to the shapes shown in FIGS. 5a to 5c above, and can be any pointed shape as long as it can play a capillary adsorption role to atomize the substrate. It is sufficient to guide it to the vicinity of the heating electrode 120 .

Furthermore, according to the capillary adsorption principle of the pointed end 117 , the smaller the pointed angle of the pointed end 117 is, the better the capillary adsorption capability is. During the processing, the appropriate pointed angle shape and angle size can be selected according to the actual situation.

The oil guiding groove 113 further includes an oil guiding end 116 connected to the pointed end 117 . The side wall of the oil guiding end 116 is cylindrical, including but not limited to a cylindrical structure.

Please refer to FIG9 , the distance between the bottom of the oil guide groove 113 and the first end face 111, that is, the depth of the oil guide groove 113 decreases as the distance from the oil guide end 116 to the pointed end 117 increases. It should be noted that the meaning of the depth of the oil guide groove 113 decreasing as the distance from the oil guide end 116 to the pointed end 117 increases means that the depth of the oil guide groove 113 decreases as the distance from the oil guide end 116 to the pointed end 117 increases, and it does not exclude the situation that the depth of the oil guide groove 113 at a certain position suddenly increases and then decreases as the distance from the oil guide end 116 to the pointed end 117 increases, or the situation that the depth of the oil guide groove 113 at a certain position does not change as the distance from the oil guide end 116 to the pointed end 117 increases.

That is, the groove depth of the pointed end 117 of the oil guide groove 113 is smaller than the groove depth of the oil guide end 116, forming a slope. Under the action of gravity, the atomized matrix will flow along the slope from the oil guide end 116 to the pointed end 117. Under the dual effects of gravity and capillary adsorption force, the oil guide groove 113 can maximize the introduction of the atomized matrix into the vicinity of the heating point of the heating electrode 120, thereby improving the atomization efficiency of the product.

Referring again to FIG. 3 and FIG. 4 , the heating electrode 120 includes a heating main body 121, which generates heat and generates heat radiation around the heating main body 121 to form a heating zone, and the end of the pointed end 117 is located in the above-mentioned heating zone. The heating zone includes a first heating zone and a second heating zone, and the temperature of the first heating zone is greater than the temperature of the second heating zone. The pointed end 117 guides the atomized substrate to the first heating zone with a higher heating temperature, which is more conducive to the atomization of the atomized substrate.

According to the thermal simulation results of the heating electrode, when the electrode generates heat and generates heat radiation to the surrounding side, the temperature is concentrated in certain areas with the highest temperature. This area is called the core heating point. The first heating area is the core heating point of the heating body 121.

It is understandable that the heating area of the heating main body 121 needs to have different temperatures, which can be achieved through a variety of methods. For example, in some embodiments, the heating main body 121 is achieved by heating with a resistor, and the heating temperature of the heating main body 121 is the same everywhere. It is a curve, and the heat radiation generated at various locations of the heating main body 121 at least partially overlaps, and the heat radiation overlap of the first heating zone is greater than that of the second heating zone, so that the temperature of the first heating zone can be greater than that of the second heating zone.

The position of the core heating point is related to the shape of the heating body 121, and is usually located at the inflection point of the curve. The thermal radiation overlap generated at the inflection point of the curve is higher, so the temperature is higher. The actual position of the core heating point can be determined based on the thermal simulation results.

For example, in some other embodiments, the heating body 121 includes a first heating section and a second heating section, the heating temperature of the first heating section is greater than the heating temperature of the second heating section, the first heating section generates heat radiation to the surrounding side of the heating body 121 to form the above-mentioned first heating zone, and the second heating section generates heat radiation to the surrounding side of the heating body 121 to form the above-mentioned second heating zone. In these embodiments, by utilizing the different temperatures of various parts of the heating body 121 itself when the heating body 121 is heated, the first heating zone and the second heating zone with different temperatures are generated when heat is radiated outward, and it is also possible to achieve that the heating zone of the heating body 121 has regions with different temperatures.

Specifically, when the resistance values of various parts of the heating main body 121 are the same or similar, that is, when the heating temperature of various parts of the heating main body 121 is the same, referring to Figures 3 and 4, the specific shape of the heating main body 121 is S-shaped, and the distance between the first heating area and the reference line segment formed by connecting the two ends of the heating main body 121 is greater than the distance between the second heating area and the reference line segment. The S shape is a conventional shape of the heating electrode 120, and the heating temperature and service life are better. Of course, other shapes can also be used. The core heating point of the heating main body 121 with different shapes is determined according to its thermal simulation results.

According to the arrangement of the S-shaped heating body 121 on the first end surface 111, correspondingly, there are two oil guide grooves 113, and the two oil guide grooves 113 are respectively located on both sides of the heating electrode 120, and the pointed ends 117 of the two oil guide grooves 113 are closer to the first heating area than other parts of the oil guide grooves 113. The arrangement of the heating body 121 and the oil guide grooves 113 can fully utilize the space of the first end surface 111.

The S-shaped heating body 121 generally includes two first heating zones, which are located on both sides of the reference line segment, and the oil guide groove 113 includes two pointed ends 117, one of which is close to one of the first heating zones. Therefore, the atomized matrix of one oil guide groove 113 can be guided to the two first heating zones of the heating body 121 through the two pointed ends 117. High atomization efficiency.

Obviously, it is understandable that according to the positions of the first heating zones of the heating main body 121 of different shapes, the number of pointed ends 117 of the oil guide groove 113 can be set accordingly, so that the different pointed ends 117 of an oil guide groove 113 respectively point to the first heating zones of the heating main body 121 to improve the atomization efficiency.

Of course, the number of pointed ends 117 of each oil guide groove 113 also affects the amount of aerosol produced by atomization. Generally speaking, under the same conditions, the more pointed ends 117 there are, the greater the amount of aerosol produced by atomization. If the amount of aerosol is too small, it will affect the user's taste, and if the amount of aerosol is too large, it will easily cause the user to choke. Therefore, the actual number of pointed ends 117 of the oil guide groove 113, such as one, two or more, can also be selected according to the user's better experience during use to obtain a better amount of aerosol. When the number of oil guide grooves 113 is two or more, the number of pointed ends 117 on each oil guide groove 113 can be equal or unequal.

The heating electrode 120 further includes a first heating electrode contact pad 122 and a second heating electrode contact pad 123 . The first heating electrode contact pad 122 and the second heating electrode contact pad 123 are respectively connected to two ends of the heating body 121 .

The first heating electrode contact pad 122 and the second heating electrode contact pad 123 are designed to be disc-shaped, with a large area, and can be in contact with an external circuit. Specifically, they can be connected to the external circuit through conductive needles, conductive columns, welding leads, etc. Of course, since the first heating electrode contact pad 122 and the second heating electrode contact pad 123 only play the role of electrical connection, the first heating electrode contact pad 122 and the second heating electrode contact pad 123 can also be designed into different shapes according to needs, and this application will not be specifically limited.

In order to detect the heating temperature of the first end surface 111 and ensure the atomization effect, the atomization assembly 100 further includes a temperature measuring electrode 130 disposed on the first end surface 111 .

Specifically, the temperature measuring electrode 130 includes a temperature measuring body 131, a first temperature measuring electrode contact plate 132 and a second temperature measuring electrode contact plate 133. The temperature measuring body 131 surrounds the heating electrode 120 and the oil guide groove 113. The first temperature measuring electrode contact plate 132 and the second temperature measuring electrode contact plate 133 are connected to the temperature measuring body 131 and are spaced apart in the circumferential direction of the temperature measuring body 131.

The temperature measuring body 131 is in the shape of a ring, covering the entire heating surface, with fast temperature sensing speed and good temperature detection effect. The first temperature measuring electrode contact plate 132 and the second temperature measuring electrode contact plate 133 can be designed It is disc-shaped, has a large area, and can be in contact with an external circuit. Specifically, it can be connected to the external circuit through a conductive needle, a conductive column, a welding lead, etc. Of course, since the first temperature measuring electrode contact disc 132 and the second temperature measuring electrode contact disc 133 only play the role of electrical connection, the first temperature measuring electrode contact disc 132 and the second temperature measuring electrode contact disc 133 can also be designed into different shapes according to needs, and this application will not be specifically limited.

The present application also provides a method for preparing the above-mentioned atomizing assembly 100, and the method comprises the following steps:

S10, a step of forming the atomizing main body 110: obtaining the atomizing main body 110 with the oil guide groove 113 provided on the first end surface 111.

The atomizing body part 110 is made by molding an atomizing body raw material. The atomizing body raw material is selected from alumina ceramic raw material or silicon oxide ceramic raw material and is molded by dry pressing or injection molding.

The oil guide groove 113 may be formed on the first end surface 111 of the atomizing body 110 after the atomizing body 110 is formed, or may be formed during the forming process of the atomizing body 110 .

S20 , heating electrode 120 forming step: forming the heating electrode 120 on the first end surface 111 .

The step of forming the heating electrode 120 specifically includes: printing the heating electrode 120 on the first end surface 111 using a first conductive paste through a printing process, and then baking, curing and sintering to form the heating electrode 120.

The first conductive paste is configured from a heating electrode material, and the heating electrode material is usually a nickel-chromium alloy, an iron-chromium-aluminum alloy, a copper alloy, a silver-palladium alloy, or the like.

The baking, curing and sintering process is as follows: the atomizing body 110 after printing the heating electrode is placed in a blast drying oven and baked at 60-120° C. for 10-30 minutes, and then placed in a vacuum furnace and sintered at a suitable temperature curve according to the material characteristics.

In some embodiments, the heating electrode 120 may be formed by the following steps: sputtering the heating electrode 120 on the first end surface 111 by a metal sputtering process.

The method for preparing the atomizing assembly 100 further includes S30 , a step of forming the temperature measuring electrode 130 .

The step of forming the temperature measuring electrode 130 specifically includes: printing the temperature measuring electrode 130 on the first end surface 111 using the second conductive paste through a printing process, and then baking, curing and sintering to form the temperature measuring electrode 130 .

The second conductive paste is made of temperature measuring electrode materials, which are usually platinum-rhodium alloys, platinum, nickel-chromium, nickel-chromium-silicon, nickel-chromium, copper-nickel, nickel-chromium-iron, copper, etc. Thermistor properties of materials.

The baking, curing and sintering process is as follows: the atomizing body 110 with the temperature measuring electrode printed thereon is placed in a blast drying oven and baked at 60-120° C. for 10-30 minutes, and then placed in a vacuum furnace and sintered at a suitable temperature curve according to the material characteristics.

In some embodiments, the temperature measuring electrode 130 may also be formed by the following steps: sputtering the temperature measuring electrode 130 on the first end surface 111 by a metal sputtering process.

When both the heating electrode 120 and the temperature measuring electrode 130 are formed by the printing process, the step of forming the temperature measuring electrode 130 can be performed after the step of forming the heating electrode 120, or before the step of forming the temperature measuring electrode 130, or the step of forming the temperature measuring electrode 130 and the step of forming the heating electrode 120 can be performed simultaneously. When the steps are performed simultaneously, specifically, the heating electrode 120 is printed on the first end surface 111 and then heated and cured, and then the temperature measuring electrode 130 is printed on the first end surface 111 and then heated and cured. Of course, the order of the printing and curing steps of the heating electrode 120 and the temperature measuring electrode 130 can be exchanged, and then the heated and cured heating electrode 120 and the temperature measuring electrode 130 are placed in a vacuum furnace together with the atomizing body 110, and sintered and formed by selecting a suitable temperature curve according to the material characteristics.

The method for preparing the atomizer assembly 100 further includes: S40, a resistance testing step.

Use resistance detection equipment to detect the resistance between the first heating electrode contact pad 122 and the second heating electrode contact pad 123, and the resistance between the first temperature measuring electrode contact pad 132 and the second temperature measuring electrode contact pad 133 to ensure that the product resistance is within the specified range and select defective products for removal.

Referring again to Figures 1 and 2, and also to Figure 8, the oil storage assembly in the atomization module of the present application is the oil storage assembly 200, and the oil storage assembly 200 includes a first oil storage portion 210. In combination with Figure 7, the atomization main body 110 also includes a second end face 112 arranged opposite to the first end face 111, and the first oil storage portion 210 is arranged on the second end face 112.

In order to increase the contact area between the oil storage assembly 200 and the atomizing body 110 and make the oil flow smoother, the atomizing body 110 is also formed with an oil inlet groove 115 which is recessed compared to the second end face 112. The atomizing body 110 also includes a core column 114 located in the oil inlet groove 115. One end of the first oil storage part 210 is inserted into the oil inlet groove 115 and sleeved on the core column 114.

After the first oil storage portion 210 is inserted into the oil inlet groove 115, the outer wall of the first oil storage portion 210 fits with the side wall of the oil inlet groove 115, and the inner wall of the first oil storage portion 210 fits with the side wall of the stem 114. The first oil storage part 210 and the atomizing body part 110 are fitted so that the contact area between the first oil storage part 210 and the atomizing body part 110 is larger. In addition, the provision of the oil inlet groove 115 is also conducive to the assembly of the first oil storage part 210, so that the first oil storage part 210 and the atomizing body part 110 can be assembled into an integral structure.

It should be understood that the oil inlet groove 115 on the second end surface 112 and the oil guide groove 113 on the first end surface 111 should be separated in the axial direction of the atomizing body 110 to prevent the oil in the first oil storage part 210 in the oil inlet groove 115 from directly entering the oil guide groove 113 .

Furthermore, the end surface of the stem 114 extends out of the second end surface 112 of the atomizing body 110 , so that the contact area between the first oil storage portion 210 and the atomizing body 110 is further increased.

In some embodiments, the oil storage assembly 200 further includes a second oil storage portion 220 sleeved outside the first oil storage portion 210 , and the porosity of the second oil storage portion 220 is greater than the porosity of the first oil storage portion 210 .

The double-layer structure of the oil storage component 200 adopts a variable porosity design. According to the principle of capillary action, the atomized matrix will flow from the high porosity area to the low porosity area along the gaps of the porous material. Therefore, the atomized matrix will flow from the second oil storage part 220 to the first oil storage part 210, and the atomized matrix will be continuously replenished to the first oil storage part 210, which not only enhances the oil locking effect of the oil storage component 200, but also can concentrate the atomized matrix outside the oil storage component 200 at the central part and conduct it to the atomizing main body 110, thereby enhancing the utilization rate of the atomized matrix.

The first oil storage part 210 and the second oil storage part 220 are usually made of chemical fibers, such as oil storage cotton, etc., and the specific optional materials are long fibers with composite skin-core structures such as PP/PA, PET/PA, and pure PET. Of course, the first oil storage part 210 and the second oil storage part 220 can also be made of materials such as porous ceramics.

The atomized matrix is poured into the first oil storage part 210 and the second oil storage part 220 in advance by a machine. When the user uses it, the atomized matrix in the first oil storage part 210 is first absorbed by the atomizing body part 110, and then the atomized matrix in the second oil storage part 220 is conducted to the first oil storage part 210 for continuous replenishment, and finally the atomized matrix is atomized at the first end surface 111 of the atomizing body part 110.

After the first oil storage section 210 and the second oil storage section 220 are assembled with the atomizing body 110, the atomized matrix can be adsorbed along the side wall of the core column 114 of the atomizing body 110 and then flow to the heating electrode 120, while being conducted along the second oil storage section 220 to the first oil storage section 210, entering the atomizing body 110 and then flowing to the heating electrode 120. Under the action of the oil guide groove 113, the atomized matrix is quickly concentrated around the heating area, thereby achieving efficient atomization.

The present application also provides an electronic atomizer, which includes an atomization module. The specific structure of the atomization module refers to the above embodiment.
