The base 210 is used for sucking liquid from the liquid storage cavity 110, and the heating element 220 is used for heating and atomizing the liquid in the base 210 to form smoke. The base 210 may be made of a porous ceramic material, such that the base 210 has a plurality of pores therein to form a certain porosity, thereby generating a capillary force for absorbing liquid, such that the liquid penetrates into the base 210. The porosity can be defined as the percentage of the volume of micropores in an object to the total volume of the material in a natural state, the porosity of the substrate 210 can be in a range of 30% -70%, meanwhile, the substrate 210 made of the porous ceramic material has good high temperature resistance, the liquid buffered in the substrate 210 does not chemically react with the substrate 210 at a high temperature, waste of the liquid due to participation in unnecessary chemical reactions is prevented, the amount of smoke generated in the atomization core 200 in unit time due to waste of the liquid is prevented, and harmful substances generated due to participation in chemical reactions of the liquid can also be avoided.

Referring to fig. 7 and 9, the base 210 includes a protrusion 211 and a main body 212, the base 210 is disposed transversely, the base 210 may be cylindrical or elliptical, the protrusion 211 is disposed in the middle of the base 210, the protrusion 211 may be prism-shaped, the protrusion 211 protrudes a certain height toward the mouthpiece 121 relative to the surface of the main body 212, the protrusion 211 is located in the inhalation passage 120, the installation notch 421 of the second sealing member 420 is matched with the main body 212, and the second sealing member 420 abuts against the side surface of the protrusion 211, so that the protrusion 211 plays a role in positioning the installation of the second sealing member 420, and the installation stability and the sealing effect of the second sealing member 420 are improved.

The upper surface of the first sealing member 410 is further concavely formed with a sinking groove 411, in the installation process of the atomizing core 200, two ends of the main body part 212 are located outside the air suction channel 120 and are matched with the sinking groove 411, that is, the first sealing member 410 can play a role in positioning and bearing the whole atomizing core 200, and the installation accuracy and the installation stability of the atomizing core 200 are improved. The main body 212 does not completely fill the entire sinking groove 411, so that a certain residual space exists between the end surface of the main body 212 and the end wall of the sinking groove 411, which residual space forms a liquid guiding gap 411a, see fig. 2. Through setting up at this drain space 411a, the liquid in the stock solution chamber 110 can get into this drain space 411a fast and with the whole terminal surface contact of main part 212, improves the area of contact of main part 212 and liquid for liquid in the stock solution chamber 110 can permeate to atomizing core 200 inside under the effect of capillary fast. The dry burning phenomenon caused by insufficient liquid supply in the atomizing core 200 is prevented, and meanwhile, sufficient liquid is stored in the atomizing core 200, so that the generated smoke amount in unit time can be effectively ensured, and the smoke has sufficient concentration. The reduction of the amount of smoke generated in unit time due to insufficient liquid in the atomizing core 200 is avoided.

The main body 212 may further have a liquid guide hole 212a formed therein, the liquid guide hole 212a may extend in the lateral direction such that the central axis of the liquid guide hole 212a coincides with the central axis of the main body 212, and the liquid guide hole 212a may penetrate both end surfaces of the main body 212 such that the liquid guide hole 212a communicates with the reservoir chamber 110 through a liquid guide gap 411 a. A part of the liquid in the reservoir 110 enters the atomizing core 200 through the micro-holes, and another part of the liquid directly enters the atomizing core 200 through the liquid guide hole 212 a. Therefore, through setting up drain hole 212a, the diameter of drain hole 212a can be 1mm ~ 3mm, and drain hole 212a is macrostructure promptly, because the aperture of the drain hole 212a of this macrostructure obviously exceeds the interior micropore of main part 212 aperture a plurality of orders of magnitude, makes liquid can pass through this drain hole 212a and get into inside atomizing core 200 fast, further ensures that the buffer memory has sufficient liquid in atomizing core 200, effectively guarantees the produced smog volume in the unit interval, ensures that smog has sufficient concentration.

The upper surface of the protrusion 211 is an atomizing surface 211a, the atomizing surface 211a may be a plane, the atomizing surface 211a faces away from the battery 320 and faces the nozzle opening 121, and in general, the atomizing surface 211a faces upward and faces away from the battery 320, but does not face downward and faces the battery 320. The heating element 220 may be in the form of a heating film, the heating film may be in an S-shaped bent shape, and the heating film is also made of a metal material with good thermal conductivity. The electrode 230 may also be attached to the atomization surface 211a, and the electrode 230 includes a positive electrode connected to one point of the heat generating film and a negative electrode connected to the other end of the heat generating film. The atomizing core 200 may further include pins 240, the pins 240 are disposed through the base 210, the number of the pins 240 is two, the lower ends of the two pins 240 are electrically connected to the battery 320, the upper end of one pin 240 is connected to the positive electrode, and the upper end of the other pin 240 is connected to the negative electrode. The power supply of the battery 320 to the heating element 220 is realized through the combined action of the pin 240 and the electrode 230. When the battery 320 supplies power to the heating element 220, the liquid adsorbed to the vicinity of the atomization surface 211a absorbs heat generated by the heating element 220, and is atomized to form smoke that can be sucked by a user.

It is understood that in other embodiments, pins 240 may not be disposed through base 210, as long as pins 240 enable electrical connection between electrode 230 and battery 320. Of course, the atomizing core 200 may not include the pin 240, and the battery 320 is directly electrically connected to the electrode 230 through the pogo pin.

With a conventional atomizing core, the atomizing surface is usually disposed toward the battery, and the heating element is disposed on the atomizing surface, so the mist generated on the atomizing surface must bypass the atomizing core itself and be absorbed by the user. And the air suction channel is communicated with the accommodating cavity for accommodating the battery, and the air entering the air inlet hole enters the air suction channel through the accommodating cavity.

Referring to fig. 2, in the electronic atomizing device 10 of the above embodiment, the atomizing surface 211a is disposed facing the nozzle opening 121, and the heating element 220 is disposed on the atomizing surface 211 a. When the heat generating body 220 generates heat, the liquid on the atomizing surface 211a absorbs the heat and atomizes the generated mist, without passing around the atomizing core 200 itself, directly into the air suction passage 120 until reaching the mouthpiece 121 to be sucked by the user. Thereby reducing the loss of the smoke generated when the smoke passes around the atomizing core 200, ensuring that enough smoke quantity is effectively absorbed by the user in unit time, and improving the effective smoke quantity generated by the electronic atomizing device 10 in unit time. Moreover, the distance from the atomizing surface 211a to the nozzle opening 121 is relatively small, so that the path through which the smoke flows to the nozzle opening 121 is shortest, the loss of the smoke in the air suction channel 120 can be reduced, and the effective smoke amount generated by the electronic atomizing device 10 in unit time can be ensured. Therefore, when the effective smoke amount of the electronic atomization device 10 is the same, the power of the battery 320 can be reduced, which is beneficial to reducing the consumption of the electronic atomization device 10 on the electric energy and improving the cruising ability of the battery 320.

Meanwhile, when the user sucks on the suction nozzle opening 121, the external air passes through the air inlet hole 314, the air guide passage 313 and the suction passage 120 in order to be sucked by the user. Because the air guide channel 313 and the accommodating cavity 311a are separated and independently arranged, the air entering the air inlet hole 314 is prevented from entering the air suction channel 120 through the accommodating cavity 311a, the interference of the accommodating cavity 311a on the stability of the air flow is avoided, the air is prevented from passing through the accommodating cavity 311a and the fluctuation of the smoke quantity is avoided, the air flow finally entering the air suction channel 120 from the independent air guide channel 313 is more stable, the stability of the smoke quantity in the air suction channel 120 is improved, and the influence of the fluctuation of the smoke quantity on the user experience is avoided.

Furthermore, since the air suction channel 120 is isolated from the accommodating cavity 311a for accommodating the battery 320, the condensate generated during the atomization process cannot further enter the accommodating cavity 311a, so that the condensate is prevented from corroding the battery 320 in the accommodating cavity 311a, short circuit is prevented, and the service lives of the battery 320 and the whole electronic atomization device 10 are prolonged.

Referring to fig. 10, the present invention further provides an atomizer, which includes the housing 100, the connecting assembly 400 and the atomizing core 200 of the electronic atomizing device 10.
