Description

Technical Field

[0001] The invention relates to the technical field of electronic cigarettes, in particular to a porous ceramic substrate and an atomizing core. Background Art

[0002] The porous ceramic matrix is ​​a ceramic material with a large number of tiny pores. Its pore structure can be interconnected. These pores provide channels for the adsorption and transmission of liquids. The porous ceramic matrix has a high specific surface area, which enables it to effectively adsorb and carry liquids. The atomizer core is a component made using the porous ceramic matrix as a key component. It is mainly used to atomize the liquid. The upper surface of the ceramic matrix is ​​provided with an oil guide groove. The smoke oil penetrates into the atomization surface through the oil guide groove and is atomized by the heating component. However, there is a situation where the oil guide effect is not good. Specifically, the atomization surface is larger than the oil guide surface, which is prone to dry burning and temperature inconsistency, thereby affecting the taste.

[0003] For example, a Chinese patent with a publication number of "CN219373784U" discloses a porous ceramic atomization core with a boss structure, which includes a porous ceramic substrate, an atomization surface, an oil sealing surface, a heating circuit, a boss structure, an oil guide groove and an oil guide surface. The above oil guide groove is formed by arranging a boss structure on one side of the oil sealing surface of the porous ceramic substrate, and the bottom surface of the formed oil guide groove and the side surface of the boss structure are used to significantly increase the contact area with the smoke oil, which is beneficial to gas exchange. Another example is a Chinese patent with a publication number of "CN219108744U" discloses an atomization core and an electronic cigarette for an electronic cigarette, which includes a porous ceramic body, a connection surface, an atomization surface, a heating layer and a temperature measuring layer. The above device ensures that the temperature change near the atomization surface can be quickly and accurately sensed by the temperature measuring layer by arranging at least part of the temperature measuring layer on the connection surface, and the temperature measuring layer does not occupy the atomization surface space, and the atomization efficiency is high;

[0004] In the application process of the above technical solution, although it has certain advantages, some problems are also exposed in actual use scenarios. Specifically, the heating elements and temperature measuring elements are mostly installed in a fixed manner. This fixed installation method can indeed provide a certain degree of stability during use, ensuring that the various components are in a relatively fixed position when the equipment is operating normally, ensuring the orderly progress of the work. However, in daily use, the atomizer core needs to be regularly removed and cleaned due to residual smoke oil. At this time, the fixedly installed heating elements and temperature measuring elements cannot be removed, which brings great inconvenience to the cleaning work. Since they cannot be disassembled, it is difficult to clean them every time. Thoroughly cleaning the dead corners of the heating element and the temperature measuring element causes the residue of the e-liquid to accumulate in these parts. Moreover, during the cleaning process, even if the user is very careful, the removal of the atomizer core will inevitably come into contact with the surrounding components, which can easily touch the heating element and the temperature measuring element, thereby increasing the risk of damage to them. This situation not only affects the cleaning effect of the equipment, but may also shorten the service life of the heating element and the temperature measuring element, thereby affecting the performance and stability of the entire equipment. It can be seen that the existing technology has certain defects and deficiencies in this regard, and it is urgently needed to be improved and optimized to enhance the overall user experience and reliability of the equipment.

DETAILED DESCRIPTION

[0031] See also Figure 1 The present invention provides an atomizer core, including an atomizer core body 7, wherein the porous ceramic body 1 is movably installed inside the atomizer core body 7.

[0033] The oil guide assembly 2 includes an oil guide groove 21, which is opened at the top of the porous ceramic body 1, and an oil guide arc groove 22 is opened at the bottom of the oil guide groove 21. The inside of the oil guide arc groove 22 is fixedly connected with a convex block 23 at equal intervals, and the inner side of the oil guide groove 21 is evenly spaced. The longitudinal guide groove 24 is opened at equal intervals. In the oil guide assembly 2, the oil guide groove 21 and the oil guide arc groove 22 at the bottom are combined to increase the contact area between the porous ceramic body 1 and the smoke oil, and improve the smoothness of the oil guide. The convex block 23 and the longitudinal guide groove 24 further expand the oil guide space, increase the contact area, and shorten the thickness of the ceramic body, so that the oil guide is more sufficient, and the anti-dry burning ability and atomization are enhanced. The amount is improved, the taste is improved, and the atomization effect is optimized. The installation mechanism 3 is convenient for the installation and disassembly of the temperature measuring element 4, and it is convenient to repair and replace it, which is beneficial to the maintenance and use of the equipment, improves the practicability and economy of the device, and avoids the situation where the temperature measuring element 4 is difficult to clean or damaged and affects the use of the entire atomization core. The clamping mechanism 5 makes the connection between the heating element 6 and the bottom of the porous ceramic body 1 stable and easy to disassemble and assemble, which is convenient for replacing the heating element 6 when it is damaged, and is also beneficial for cleaning related components. The overall maintainability and ease of use of the atomization core are improved, ensuring that the atomization core can operate stably and efficiently during the working process.

[0034] See also Figure 1-Figure 4 The bottom of the porous ceramic body 1 is arranged in an arc shape, and the overall cross-sectional shape of the oil guide arc groove 22 is also arranged in an arc shape. The bottom of the porous ceramic body 1 and the oil guide arc groove 22 are both arc-shaped and match each other in structure, so that the fit between the two is higher, which is conducive to the uniform distribution of heat at the bottom of the ceramic body and improves the heat transfer efficiency. For the oil guide arc groove 22, the arc shape can better guide the flow of smoke oil, reduce the residue of smoke oil in the groove, and enable the smoke oil to penetrate into the porous ceramic body 1 more smoothly, further enhancing the oil guide effect. The arc design of the bottom of the porous ceramic body 1 not only works with the oil guide arc groove 22 to optimize the oil guide process, but also has more advantages in space utilization. Compared with other shapes, it may occupy less vertical space, which is conducive to the compact design of the overall structure of the atomization core. At the same time, this arc structure also has certain advantages in mechanical properties, and can better withstand internal and external pressures, thereby improving the stability and durability of the porous ceramic body 1.

[0035] See also Figure 1-Figure 4 and Figure 8 The mounting mechanism 3 includes a side slide groove 31 and a mounting groove 32. The side slide groove 31 is opened on both sides of the front and back of the porous ceramic body 1. The inside of the side slide groove 31 is fixedly connected to a limit spring 33. The end of the limit spring 33 is fixedly connected to a push rod 34.

The inner side of the limit frame 35 clamps a temperature measuring element 4. The temperature measuring element 4 includes a fixing block 41. The fixing block 41 is inserted into the inner side of the limit frame 35. The fixing block 4 1 is fixedly connected with a temperature sensing electrode 42 in the middle of the inner side of the fixing block 41, a connecting section 43 is fixedly connected at the front end of the temperature sensing electrode 42 on the inner side of the fixing block 41, and a temperature measuring section 44 is fixedly connected to the inner end of the connecting section 43. The overall cross-sectional shape of the push rod 34 and the inner cavity of the side slide groove 31 are both set to a convex shape, and a groove 36 is opened in the middle of the outer side of the limit frame 35. The overall cross-sectional shape of the limit frame 35 is set in an L shape, and the front view shape of the limit frame 35 is set in a concave shape. The L-shaped limit frame 35 can better clamp the temperature measuring element 4, and the limit spring 33 in the side slide groove 31 provides elasticity for the push rod 34. The push rod 34 is supported by the limit frame 35, so that the push rod 34 can stably push the limit frame 35 to clamp the temperature measuring element 4. The convex push rod 34 and the side sliding groove 31 cavity design ensure the stability and accuracy of the push rod 34 during the sliding process, and prevent it from deflecting or falling off. The installation groove 32 provides a suitable position space for the installation of the temperature measuring element 4, making the entire installation structure more compact and reasonable. The special shape design of the limit frame 35, especially the L-shaped and concave design, can better fit and clamp the fixed block 41 of the temperature measuring element 4, ensuring that the temperature sensing electrode 42, the connecting section 43 and the temperature measuring section 44 are fixed. The stable installation improves the reliability and stability of the connection. The setting of the groove 36 facilitates the user to operate when the temperature measuring element 4 needs to be disassembled. The user only needs to push the groove 36 to easily push the limit frame 35 to move outward, so that the push rod 34 squeezes the limit spring 33 to contract, thereby realizing the rapid removal of the temperature measuring element 4. This design makes the disassembly and assembly of the temperature measuring element 4 simple and convenient, facilitates the daily cleaning and maintenance of the equipment, and the replacement operation when the temperature measuring element 4 is damaged, greatly improves the practicability and maintainability of the entire atomization core device, and ensures the normal operation and stable performance of the equipment.

[0036] See also Figure 1-Figure 7The card-mounting mechanism 5 includes a slot 51 and a limiting slot 52. The slot 51 is provided at both ends of the bottom of the porous ceramic body 1, and the limiting slot 52 is provided at the upper ends of the front and back sides of the porous ceramic body 1. The rear side of the limiting slot 52 is connected to the interior of the slot 51. An insert plate 53 is inserted into the inner side of the slot 51. The upper end of the outer side of the insert plate 53 is fixedly connected to a limiting block 54. The end of the limiting block 54 is inserted into the inner side of the limiting slot 52. A card frame 55 is fixedly installed at the bottom of the limiting block 54. The limiting components 56 are fixedly installed at the four corners of the card frame 55. The heating element 6 is installed at the bottom of the card frame 55 through the limiting component 56. The top of the limiting block 54 is provided with a first inclined surface 57, and the bottom of the limiting block 54 is provided with a second inclined surface 58. The insert plate 53 is inserted into the inner side of the slot 51. 53 is set as an elastic plate made of spring steel, the limiting component 56 includes a sleeve 561, the sleeve 561 is fixedly installed at the four corners of the bottom of the card frame 55, the inner side of the sleeve 561 is fixedly connected with a torsion spring 562, the inner end of the torsion spring 562 is fixedly connected with a rotating disk 566, the inner side of the rotating disk 566 is fixedly connected with a connecting frame 563, the inner end of the connecting frame 563 is fixedly connected with a limiting arc frame 564, the end of the limiting arc frame 564 is inserted at the four corners of the heating element 6, and the bottom of the rotating disk 566 is fixedly installed with a toggle frame 565. The heating element 6 includes a bottom plate 61, both ends of the bottom plate 61 are fixedly connected to a limiting ring 62, the end of the limiting arc frame 564 is inserted into the inner side of the limiting ring 62, and the limiting arc frame 564 and the limiting ring 62 are both torsionally connected. The spring 562 is set in an arc shape in a concentric circle state, and an electric heating wire 63 is fixedly installed on the inner side of the bottom plate 61. The side shape of the electric heating wire 63 is set to be an arc shape, and the top of the electric heating wire 63 is fitted and connected with the bottom arc surface of the porous ceramic body 1. The design layout of the slot 51 and the limit groove 52 is reasonable, which provides an accurate position for the installation of the plug plate 53 and the limit block 54, so that the plug plate 53 can be stably inserted into the slot 51, and the limit block 54 can be accurately inserted into the limit groove 52, thereby realizing the effective connection between the clamping mechanism 5 and the porous ceramic body 1. The plug plate 53 is an elastic plate made of spring steel material, which has good elasticity and toughness. The first inclined surface 57 on its top can play a guiding role when inserted into the slot 51, so that the plug plate 53 can be smoothly inserted during the insertion process. When the card frame 55 is pulled downward, the force guide of the second inclined surface 58 can cause the limit block 54 to squeeze the plug plate 53 and bend, thereby conveniently pulling the plug plate 53 out of the slot 51, realizing quick disassembly, and facilitating cleaning and maintenance. The design of the limit assembly 56 is exquisite and practical. The torsion spring 562 in the sleeve 561 provides the resetting power for the turntable 566. When the bottom plate 61 is attached to the bottom of the card frame 55, the toggle frame 565 is twisted to drive the turntable 566 to rotate.During the rotation of the turntable 566, the torsion spring 562 is squeezed to put it in a compressed state. When the bottom plate 61 is fitted, the toggle frame 565 is released, and the torsion spring 562 is reset to drive the connecting frame 563 and the limiting arc frame 564 to rotate. The limiting arc frame 564 is rotated and inserted into the inner side of the limiting ring 62 at the four corners of the heating element 6. Through the mutual limiting effect of the limiting arc frame 564 and the limiting ring 62, the bottom plate 61 can be stably installed on the bottom of the card frame 55, thereby realizing the rapid installation of the heating element 6. In addition, this arc-shaped design cooperates with the concentric circle state of the torsion spring 562 to ensure the rotation The smoothness and stability of the heating element 6 are improved. The electric heating wire 63 installed on the inner side of the bottom plate 61 of the heating element 6 has an arc-shaped side and is connected to the arc surface of the bottom of the porous ceramic body 1. This design greatly increases the contact area between the electric heating wire 63 and the porous ceramic body 1, improves the heat transfer efficiency, and makes the heating more uniform, thereby optimizing the atomization effect and providing a strong guarantee for the efficient operation of the entire atomization core. Overall, these design features of the clamping mechanism 5 not only facilitate the rapid disassembly and replacement of the heating element 6, saving the use cost, but also significantly improve the convenience of subsequent cleaning and maintenance.

[0037] The working principle of the present invention is as follows: by setting the oil guide assembly 2, the bottom of the oil guide groove 21 is innovatively provided with an oil guide arc groove 22 during the use of the atomizer core. This design has many advantages. First, the coordinated setting of the oil guide groove 21 and the oil guide arc groove 22 greatly increases the contact area between the porous ceramic body 1 and the smoke oil. The oil guide arc groove 22 with an arc-shaped bottom significantly improves the smoothness of the oil guide. In addition, the longitudinal guide groove 24 and the protrusion 23 are provided on the side of the oil guide groove 21. This ingenious design further expands the space area inside the oil guide groove 21 and the oil guide arc groove 22, thereby further increasing the contact area between the porous ceramic substrate and the smoke oil. At the same time, this The design can also effectively shorten the thickness of the porous ceramic body 1, making the oil conduction more sufficient. In this way, not only the anti-dry burning ability of the porous ceramic matrix is ​​improved, but also the atomization amount is significantly increased, and the smoke after atomization becomes denser and fuller, which can further improve the taste. In addition, the bottom of the porous ceramic body 1 with an arc design cooperates with the arc-shaped electric heating wire 63. On the one hand, this cooperation method can significantly improve the contact effect between the electric heating wire 63 and the bottom of the porous ceramic body 1, ensuring that the heat transfer is more efficient; on the other hand, it also increases the contact area between the electric heating wire and the porous ceramic body 1 as much as possible, thereby greatly improving its heating effect and uniformity, and finally further optimizing the atomization effect;

[0038] By setting up the installation mechanism 3, when the temperature measuring element 4 needs to be installed during the use of the device, the temperature measuring element 4 can be filled into the inside of the installation groove 32. At this time, the fixing block 41 will be located on the inner side of the limiting frame 35, and the limiting frame 35 will push the push rod 34 inwardly through the reset of the limiting spring 33 under the action of the limiting spring 33. The inward movement of the push rod 34 can transmit the pressure of the limiting spring 33 to the limiting frame 35, so that the limiting frame 35 can stably clamp the fixing block 41 of the temperature measuring element 4, thereby making the temperature sensing electrode 42, the connecting section 43 and the temperature measuring section 44 can be stably installed in the inside of the installation groove 32. In addition, when disassembly is required, the operation is also extremely simple. Only the groove 36 needs to be pressed. At this time, the limiting frame 35 can be pushed to move toward the outside, and the push rod 34 can squeeze The limiting spring 33 causes it to move outward and shrink, and at this time, the fixing block 41 and the entire temperature measuring element 4 can be easily removed from the inside of the installation groove 32. When it needs to be installed again, similarly, it is only necessary to push the limiting frame 35 outward, put the temperature measuring element 4 into the inner side of the installation groove 32, and after loosening the limiting frame 35, the limiting spring 33 is reset to push the limiting frame 35 to clamp the fixing block 41, so as to realize the rapid installation of the temperature measuring element 4. It can be seen that the device as a whole can quickly and flexibly disassemble and repair the temperature measuring element 4, which greatly facilitates the cleaning and maintenance work of the device during use. In this way, it can not only avoid cleaning dead corners, but also if the temperature measuring element 4 is accidentally damaged during the cleaning process, it can be easily disassembled and replaced without replacing the entire atomizer core, which provides great convenience for the use of the device.

[0039] By setting the clamping mechanism 5, during the application of the device, the bottom plate 61 can be first attached to the bottom of the clamping frame 55. At this time, the toggle frame 565 is twisted to drive the rotating disk 566 to rotate. During the rotation of the rotating disk 566, the torsion spring 562 is squeezed to make the torsion spring 562 in a compressed state. When the bottom plate 61 is attached, the toggle frame 565 is released, and the torsion spring 562 drives the connecting frame 563 to rotate by its reset characteristic. The connecting frame 563 can rotate by the reset rotation to drive the limiting arc frame 564 to rotate. The limiting arc frame 564 The bottom plate 61 can be stably installed to the bottom of the card frame 55 by rotating it, and the electric heating wire 63 can be stably installed to the bottom of the porous ceramic body 1 through the mutual limiting effect of the limiting arc frame 564 and the limiting ring 62. After the installation is completed, it is only necessary to insert the elastic plug plate 53 into the interior of the slot 51, and the first inclined surface 57 at the top of the limiting block 54 guides the plug plate 53 to bend so that it can be stably inserted into the inner side of the slot 51. When the limiting block 54 contacts When the stopper 52 is touched, the plug plate 53 is reset to drive the stopper 54 to be inserted into the stopper 54. At this time, the installation of the heating element 6 is completed. If it needs to be disassembled for maintenance, it is only necessary to pull the card frame 55 downward. At this time, the second inclined surface 58 is guided by force to cause the stopper 54 to squeeze the plug plate 53 and bend. At this time, the plug plate 53 can be pulled out from the inside of the slot 51. At this time, the card frame 55 and the temperature measuring element 4 can be removed and then cleaned. If the heating element 6 is damaged and needs to be replaced, it is only necessary to push the toggle frame 56. 5 drives the turntable 566 to rotate, and at this time, the connecting frame 563 can drive the toggle frame 565 to disengage from the limiting ring 62, so that the bottom plate 61 and the heating wire can be removed from the bottom of the clamping frame 55. At this time, it is only necessary to replace a new heating element 6, and drive the connecting frame 563 and the limiting arc frame 564 to reset through the torsion spring 562 for clamping and installation. It can be seen that the atomizer core as a whole can quickly disassemble and replace the heating element 6, which greatly facilitates cleaning or subsequent maintenance and replacement work, and can effectively save the use cost.
