In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

In the present embodiment, an atomizer is provided, comprising an atomizing core, wherein, in conjunction with Figures 1-5, the atomizing core comprises a hard oil-conducting body 1 and a heating body 2, one side of the hard oil-conducting body 1 is recessed to form a groove 10, and the groove wall of the groove 10 defines an atomizing cavity; the heating body 2 is disposed in the groove 10 and the heating body 2 and the groove wall of the groove 10 are at least partially in contact and connected.

In the present solution, the groove 10 is located on one side of the hard oil-conducting body 1, and the heating element 2 is placed in the groove 10. Since the notch of the groove 10 is exposed to the outside, the heating element 2 is easier to be assembled with the hard oil-conducting body 1 from the notch direction of the groove 10, and the atomizer core after assembly will not have the problem of slurry falling off from the hard oil-conducting body 1. In addition, during the production and testing of the atomizer core, relevant parameters of the heating element 2, such as the wire diameter and wire spacing of the heating element 2, can be observed or measured from the notch of the groove 10, which solves the problem that the cylindrical ceramic heating element 2 on the market can only be tested and assembled, but the change of wire spacing during the firing process and the oxidation of the heating element 2 cannot be detected and identified, thereby ensuring the reliability of the heating element 2 and the hard oil-conducting body 1 after assembly, thereby improving the performance of the atomizer using the atomizer core of the present solution.

In this embodiment, the hard oil-conducting body 1 is made of ceramic material, especially porous ceramic material, which has good oil absorption and oil locking functions. In some embodiments, the hard oil-conducting body 1 can also be made of materials with a porous structure inside, such as glass fiber.

Furthermore, the hard oil-conducting body 1 includes a main body 11, and two side walls 12 connected to the main body 11 and arranged opposite to each other, wherein the groove 10 is formed by enclosing the main body 11 and the two side walls 12, and the heating element 2 is contact-connected to the main body 11. Since the heating element 2 is arranged in the groove 10 and contact-connected to the main body 11, the side walls 12 can prevent the heat emitted by the heating element 2 from being conducted toward both sides, and the heat emitted by the heating element 2 can be more concentratedly used for atomization of the atomized oil, thereby improving the utilization rate of the heat energy.

Specifically, in the present embodiment, the two side walls 12 are connected to the same side of the main body 11, and the length extension directions of the two side walls 12 are parallel to each other, that is, the cross-section of the hard oil-conducting body 1 is U-shaped as a whole, the peripheral corners of the main body 11 can be rounded or cut, and the peripheral corners of the side walls 12 can also be rounded or cut. The connection between the side walls 12 and the outer sides of the main body 11 can be a smooth transition. Therefore, the integrity of the atomizer core can be better. On the one hand, the corners of the atomizer core are not easily bumped and damaged. On the other hand, the hard oil-conducting body 1 is easier to position and place during the processing of the atomizer core, which is convenient for processing and assembly.

In order to improve the structural strength of the hard oil-conducting body 1 and make it less prone to damage and fracture, the direction from the main body 11 toward the groove 10 is defined as the first direction. In the first direction, the thickness of the sidewall 12 is less than the thickness of the main body 11. Specifically, in this solution, the thickness of the two sidewalls 12 in the first direction is equal, so the distance from the side of the opening of the groove 10 away from the main body 11 to the main body 11 is equal. It can be understood that the depth of the groove 10 is equal to the thickness of the sidewall 12 in the first direction, that is, the depth of the groove 10 is less than the thickness of the main body 11. In some embodiments, the thickness of the two sidewalls 12 in the first direction may also be unequal.

Further, the direction of the side wall 12 toward the groove 10 is defined as the second direction, and the thickness of the side wall 12 in the second direction is less than the thickness of the main body 11 in the first direction. Specifically, the first direction is perpendicular to the second direction. Since the thickness of the two side walls 12 in the second direction is equal, in this solution, the second direction is also the oil inlet direction, that is, the atomized oil is gradually conducted from the outside of the side wall 12 toward the direction of the groove 10. The equal thickness of the two side walls 12 in the second direction can make the amount of oil inlet from both sides of the hard oil-conducting body 1 more uniform. In some embodiments, the thickness of the two side walls 12 in the second direction may also be unequal. It is generally understood that the greater the thickness, the longer the conduction path and the slower the oil conduction speed. The specific thickness of the two side walls 12 can be adaptively adjusted according to the actual required oil conduction speed. In some embodiments, the thickness of the side wall 12 in the second direction may also be greater than or equal to the thickness of the main body 11 in the first direction, so that the volume of the atomization chamber can be larger, thereby increasing the aerosol holding capacity.

Further, the groove 10 runs through both ends of the hard oil-conducting body 1, and the cross section of the groove 10 is one of C-shaped, U-shaped, and zigzag. In the present embodiment, the cross section of the groove 10 is a zigzag shape, which is preferred. The cross section of the groove 10 is [-shaped, and the cross sections of the groove 10 at all locations in the length direction are the same, that is, the atomization cavity defined by the groove wall of the groove 10 is a cavity with a rectangular cross section. Since both ends of the groove 10 are open, the airflow can enter from one end of the atomization cavity of the groove 10, and then flow out from the other end of the atomization cavity, and the airflow velocity is uniform.

In some embodiments, the groove 10 may not pass through the end of the hard oil-conducting body 1, or the groove 10 only passes through one end of the hard oil-conducting body 1, so that at least one of the inlet airflow and the outlet airflow can pass through the opening of the groove 10 away from the main body 11.

In some embodiments, when the cross-section of the groove 10 is in the shape of a broken line, the broken line may include two, four, five or six folded edges connected in sequence, and the broken line is preferably a symmetrical structure.

In some embodiments, the cross-section of the groove 10 may also be C-shaped, U-shaped, etc.

In some embodiments, the cross-sections of the groove 10 at various locations along the length direction may be different. For example, when the cross-sectional shapes are the same, the cross-sectional dimensions of the groove 10 near the middle are smaller than those near the ends. Therefore, the airflow velocity at the middle position of the atomization chamber is greater, which can drive the aerosol formed in the middle of the heating element 2 to flow away quickly, thereby increasing the aerosol generation rate. It should be understood that the cross-sectional shapes and dimensions of the groove 10 at various locations along the length direction can be adaptively adjusted according to actual needs and are not limited here.

Furthermore, the heating element 2 includes a heating portion 21 attached to a side of the main body 11 close to the groove 10 and electrode portions 22 connected to both ends of the heating portion 21 , and the electrode portions 22 are connected to the side wall 12 .

In this embodiment, the heating portion 21 has a first heating zone located in the middle and second heating zones located on two sides opposite to the first heating zone, wherein the heating efficiency per unit area of the second heating zone is higher than that of the first heating zone, and the two second heating zones correspond to the two side walls 12 one by one, and the second heating zone is close to the corresponding side wall 12. Preferably, the heating portion 21 adopts a form of multiple diamond structures connected in sequence, wherein the short axis ends of each diamond structure are connected in sequence, and the long axis ends of the diamond structures are respectively facing the two side walls 12, so that when the atomized oil flows from the two side walls 12 to the middle of the main body 11, the heating portion 21 can atomize the atomized oil in time to improve the atomization effect.

In some embodiments, the heating element 2 can be formed by etching, stamping or other processing methods, and the shape of the heating portion 21 can include but is not limited to S-shape, mesh, folded line, rectangle, square, etc.

Further, a side of the side wall 12 facing away from the groove 10 is recessed to form a receiving space 121, and two electrode parts 22 are respectively connected to the two side walls, and the electrode parts 22 penetrate the corresponding side walls 12 and are contained in the corresponding receiving space 121. Preferably, the heating part 21 is fitted and connected to the side of the main body 11 close to the groove 10, and an electrode part 22 is provided at both ends of the length direction of the heating part 21, one of the electrode parts 22 is bent and extended toward one side wall 12 and penetrates the side wall 12, and the other electrode part 22 is bent and extended toward the other side wall 12 and penetrates the side wall 12. At this time, the two electrode parts 22 are located at different positions in the length direction of the hard oil-conducting body 1. With such a configuration, the heating part 21 can be pressed and fitted on the main body 11, ensuring the close fit between the heating body 2 and the hard oil-conducting body 1, improving the connection strength, and preventing the heating part 21 from warping.

In one embodiment, the electrode portions 22 may also be disposed at both ends of the heating portion 21 in the width direction. In this case, the two electrode portions 22 are located at the same position in the length direction of the hard oil-conducting body 1 .

In some embodiments, in conjunction with FIG5 , the two electrode portions 22 may both penetrate to the outside of the same side wall 12. Specifically, an electrode portion 22 is provided at both ends of the length direction of the heating portion 21, and the two electrode portions 22 bend and extend toward the same side wall 12 and penetrate the side wall 12, and the two electrode portions 22 are exposed on the outside of the side wall 12. With such a configuration, when electrically connecting the heating element 2, it is only necessary to connect on one side, with fewer changes in workstations and lower process costs.

Furthermore, the receiving space 121 extends to one end of the side wall 12, and the heating element 2 further includes a pin 23 connected to the electrode portion 22, one end of the pin 23 connected to the electrode portion 22 is received in the receiving space 121, and the other end of the pin 23 protrudes from the end of the side wall 12. Preferably, the receiving space 121 can be a receiving groove located outside the side wall 12, and the receiving grooves on the two side walls 12 extend toward the same end of the hard oil-conducting body 1. In this way, the two pins 23 can be respectively received in the receiving grooves of the corresponding side walls 12 and led out from the same end of the hard oil-conducting body 1. Moreover, the two pins 23 are respectively arranged outside different side walls 12, which can prevent mutual interference and reduce the wiring difficulty of the power supply pin 23. The receiving groove can be arranged at a position close to the end of the side wall 12, so that the space occupied by the receiving groove can be minimized to ensure the structural strength of the side wall 12.

If the pin 23 is exposed and higher than the outer surface of the side wall 12, the outer surface of the entire atomizer core will be uneven, affecting the oil guiding effect and assembly accuracy. If it is completely buried in the hard oil guiding body 1, the structural strength of the hard oil guiding body 1 will be reduced, and the ceramic covering its surface may fall off after being subjected to force, affecting safety and the taste of smoking. Therefore, the present application sets a receiving space 121 for receiving the pin 23 to avoid the pin 23 protruding from the outer surface of the side wall 12, which causes poor assembly. In addition, when the oil guiding cotton is wrapped on the outer surface of the side wall 12, the cotton wrapping is smoother and the oil guiding is uniform, which can avoid the problems of too fast oil feeding (oil leakage)/too slow (dry burning smell) caused by the protrusion of the pin 23.

In some embodiments, the receiving grooves on the two side walls 12 may extend toward different ends of the hard oil-conducting body 1 .

In some embodiments, the receiving groove may also be disposed on the outer side of the main body 11 at the same time.

Further, in combination with Figure 6, the atomizer of this embodiment includes an oil cup 3 with a liquid storage chamber 20 and an atomizer assembly 4 assembled on the oil cup 3, the oil cup 3 has an air outlet channel 311, the atomizer assembly 4 includes an atomizer core of any of the above items, and the atomizer assembly 4 is formed with an oil guide channel connected to the liquid storage chamber 20 and connected to the hard oil guide body 1, and an atomizer air channel connected to the outside atmosphere at one end and the air outlet channel 311 at the other end, and the atomizer chamber is a part of the atomizer air channel.

The atomizer adopts the atomization core as in the present application, and the atomization cavity of the atomization core serves as a part of the atomization airway. The atomized liquid in the liquid storage cavity 20 can be guided to the hard oil-conducting body 1, and then conducted to the heating element 2 through the hard oil-conducting body 1 to be heated and atomized to form an aerosol, and finally guided out through the air outlet channel 311 for inhalation by the user, and the reliability of the atomization performance is good.

Further, the extension direction of the groove 10 can be vertical. Specifically, the extension direction of the groove 10 can be parallel to the central axis direction of the atomizer. When this setting is adopted, the oil cup 3 can include an air guide tube, and the atomization assembly 4 can include a base 411 assembled at one end of the oil cup 3, two electrodes 412 penetrated through the base 411, and a top bracket assembled on the base 411 and sealedly connected to the air guide tube. The top bracket and the oil cup 3 enclose a liquid storage chamber 20, and the hard oil-conducting body 1 can be clamped and fixed between the top bracket and the base 411. The top bracket is provided with an oil-conducting channel connected to one side of the hard oil-conducting body 1, and the two electrode parts 22 of the heating element 2 can be electrically connected to the two electrodes 412 respectively, and the base 411 is provided with an air inlet connected to the atomization airway. In this way, the atomized liquid in the liquid storage chamber 20 can be guided to the hard oil guide body 1 and supplied to the heating element 2 through the oil guide channel. During the inhalation process, air can enter the atomization chamber of the atomization core through the air inlet of the base 411. The heating element 2 atomizes the atomized liquid to form an aerosol, which is finally discharged to the outside through the air outlet channel 311 in the air guide tube for the user to inhale.

Furthermore, the extending direction of the groove 10 is horizontal or inclined.

In this embodiment, an atomizer is shown in which the groove 10 of the hard oil-conducting body 1 is horizontally arranged (perpendicular to the central axis direction of the atomizer), wherein the oil cup 3 has a bottom wall 312, and the bottom wall 312 is provided with an oil guide hole; the atomizing assembly 4 also includes a bottom assembly 41, and the bottom assembly 41 includes a base 411 installed in the lower end of the oil cup 3 and two electrodes 412 penetrated in the base 411; the atomizing core is clamped and fixed between the base 411 and the bottom wall 312, and absorbs the atomized liquid in the liquid storage chamber 20 through the oil guide hole, and the two electrode parts 22 of the heating element 2 are electrically connected to the two electrodes 412 respectively.

Specifically, a first embedding groove 3121 is provided on the bottom side of the bottom wall 312, and a second embedding groove 4111 is provided on the top side of the base 411, and the hard oil-conducting body 1 is respectively embedded in the first embedding groove 3121 and the second embedding groove 4111; the atomizing assembly 4 also includes oil-absorbing cotton 413 stacked on the top of the ceramic oil-conducting body, and the oil-absorbing cotton 413 covers the bottom opening of the oil-conducting hole. The oil-absorbing cotton 413 can be only arranged on the top side of the hard oil-conducting body 1, and the oil-absorbing cotton 413 can also be arranged to be wrapped around the circumference of the hard oil-conducting body 1. The two electrode parts 22 of the heating element 2 are located on the side wall 12 of the bottom side of the hard oil-conducting body 1. Therefore, during the assembly process, the two electrode parts 22 of the atomizing core can be connected to the two electrodes 412 on the same side, which is convenient and quick. Moreover, since the atomizing core is embedded in the first embedding groove 3121 and the second embedding groove 4111, when the condensate flows into the atomizing chamber, the gap between the hard oil-conducting body 1 and the first embedding groove 3121 and the second embedding groove 4111 can be used to collect the condensate, and the condensate can be absorbed by the two side walls 12 of the hard oil-conducting body 1, thereby improving the utilization rate of the atomized liquid and reducing the accumulation of the condensate.

In this embodiment, the side wall 12 of the atomizing chamber and the bottom surface of the atomizer are preferably 90°, that is, the heating element 2 is arranged in a vertical state, and the external air passes along the surface of the heating element 2 after entering the atomizing chamber from the air inlet channel 313, which greatly improves the atomization effect of the heating element 2. In actual application, the side wall 12 of the atomizing chamber can also be arranged at an angle, that is, the heating element 2 is arranged at an angle, and the angle between the heating element 2 and the bottom surface of the atomizer is preferably in the range of 60 to 120°.

Furthermore, the oil cup 3 includes a cup body 31 and a suction nozzle assembly 32 assembled on the top of the cup body 31, the suction nozzle assembly 32 and the cup body 31 enclose a liquid storage chamber 20, and the suction nozzle assembly 32 has an air suction hole 3211 connected to the air outlet channel 311; the cup body 31 also has an air intake channel 313 isolated from the liquid storage chamber 20 and the air outlet channel 311, the air intake channel 313 is connected to the atomization channel, and the side wall 12 of the cup body 31 is provided with a first air intake hole 314 connecting the air intake channel 313 and the outside atmosphere.

Specifically, in the present embodiment, the air inlet channel 313, the liquid storage chamber 20 and the air outlet channel 311 are arranged in sequence in the horizontal direction and extend vertically. The first air inlet hole 314 is opened in the middle position of the side wall 12 of the cup body 31. The air inlet channel 313 and the air outlet channel 311 are respectively located on both sides of the liquid storage chamber 20. Two notches located at both ends of the atomization chamber are formed between the bottom wall 312 of the oil cup 3 and the base 411. The two notches are respectively connected to the bottom end of the air inlet channel 313 and the bottom end of the air outlet channel 311. In addition, the base 411 is provided with a second air inlet hole 4112 connected to the bottom end of the air inlet channel 313 and a third air inlet hole 4113 connected to the bottom end of the air outlet channel 311.

The second air inlet hole 4112 and the third air inlet hole 4113 can both serve as air flow channels for the microphone switch. With this arrangement, even if one of the air flow channels is blocked, the other air flow channel can still normally trigger the start of the microphone switch, thereby improving the reliability of the switch start-up. In addition, the second air inlet hole 4112 can supplement the air flow to the air inlet channel 313 to provide sufficient air, and the third air inlet hole 4113 can supplement the air flow to the air outlet channel 311. After the outside air and the aerosol in the atomization chamber are mixed, the temperature of the aerosol flowing out of the air outlet channel 311 can be lower, thereby improving the user's inhalation experience.

In this embodiment, the nozzle 321 assembly 32 includes a seal 322 and a nozzle 321. The seal 322 is made of silicone, rubber or other flexible materials. The seal 322 is installed on the upper end of the cup body 31 and is sealed with the inner wall of the liquid storage chamber 2020. The nozzle 321 is fixed to the upper end of the cup body 31 by snaps or other means to clamp and fix the seal 322 between the cup body 31 and the nozzle 321, so that the seal 322 maintains a sealed state for the liquid storage chamber 2020.
