The infrared rays can penetrate the atomizing medium 20, so that the atomizing medium 20 can absorb the infrared rays to generate heat. The heating body 300 is independently installed relative to the pot body 100 . It can be understood that the heating body 300 does not form a physical connection relationship with the pot body 100 , so that the heating body 300 can be replaced relative to the pot body 100 . In other words, the heating body 300 is configured in a first state and a second state. When the heating body 300 is in the first state, the heating body 300 will be at least partially accommodated in the accommodating cavity 130; when the heating body 300 is in the second state, The heating body 300 will be separated from the accommodating cavity 130 and located outside the accommodating cavity 130 .

In some embodiments, the base 400 and the pot body 100 are arranged along the axial direction of the heating and atomizing device 10 , and the base 400 is located above the pot body 100 . A sealing ring may be provided between the base 400 and the mounting frame 220 , so as to improve the sealing performance of the entire heating atomizing device 10 and prevent external gas or liquid from intruding through the gap between the base 400 and the mounting frame 220 . The base 400 defines an installation cavity 410 , which is also an open cavity, and the installation cavity 410 communicates with the outside world and the accommodating cavity 130 of the pot body 100 . The suction nozzle 500 is inserted into the installation cavity 410 , so that the suction nozzle 500 cooperates with the installation cavity 410 and forms a detachable connection relationship with the base 400 . The base 400 has an inner surface that bounds the mounting cavity 410 . The inner surface is recessed to form an air inlet groove 420, and the air inlet groove 420 can extend along the vertical direction; The interval angles between two adjacent air intake slots 420 may be equal. When the suction nozzle 500 is inserted into the installation cavity 410 , the suction nozzle 500 can cover the notch of the air inlet groove 420 , so that the air inlet groove 420 is covered to form the air inlet passage 421 . The air intake passage 421 communicates with the outside world and the installation cavity 410 , and the outside air will enter the installation cavity 410 through the air intake passage.

Referring to FIG. 3 , FIG. 4 and FIG. 5 , in some embodiments, the suction nozzle 500 includes a stem portion 520 and a boss portion 530 , the stem portion 520 is a columnar structure, and the boss portion 530 is connected to the outer peripheral surface of the stem portion 520 , The boss portion 530 protrudes by a certain length relative to the radial direction of the outer peripheral surface, and the radial direction can be understood as a direction perpendicular to the axial direction of the rod portion 520 . The installation cavity 410 includes a large cavity 411 and a small cavity 412. The large cavity 411 is located above the small cavity 412. The small cavity 412 is connected between the large cavity 411 and the accommodating cavity 130. The diameter of the small cavity 412 is kept constant in the vertical direction. Columnar, the diameter of the large chamber 411 changes in the vertical direction to become a cone shape, along the direction from the large chamber 411 to the small chamber 412, that is, from top to bottom, the diameter of the large chamber 411 gradually decreases, and the diameter of the large chamber 411 The caliber is larger than the caliber of the small cavity 412 . When the suction nozzle 500 is inserted in the installation cavity 410, the rod 520 is in close contact with the part of the inner surface used to define the boundary of the small cavity 412, and is spaced from the part of the inner surface used to limit the boundary of the large cavity 411; the boss The part 530 is carried on the part of the inner surface used to define the boundary of the large cavity 411 , so that the boss part 530 plays a role of limiting the installation of the entire suction nozzle 500 . When the boss portion 530 abuts against the inner surface, the suction nozzle 500 cannot be further inserted into the installation cavity 410 . An inhalation channel 510 is provided on the rod part 520, and the inhalation channel 510 extends vertically. The upper end of the inhalation channel 510 forms a suction nozzle 511 directly connected to the outside world, and the user can perform suction through the suction nozzle 511.

Referring to Fig. 3, Fig. 4 and Fig. 5, in the case where the atomizing medium 20 is a solid-liquid mixed paste, when using the heating atomizing device 10, the paste-like atomizing medium 20 can be put into the In the accommodating cavity 130 , the heating body 300 is embedded in the atomizing medium 20 , and finally the suction nozzle 500 is inserted in the installation cavity 410 . The suction nozzle 500 may not fill the entire installation cavity 410 , and there will be a gap 413 in the lower part of the installation cavity 410 , so that the suction channel 510 directly communicates with the gap 413 of the installation cavity 410 . When the user sucks at the nozzle opening 511 , outside air enters the lower space 413 of the installation cavity 410 through the air intake channel 421 , and continues to enter the inhalation channel 510 . The dotted arrows in FIG. 5 represent the gas flow paths. In the case where the heating body 300 only includes an electromagnetic induction unit, when the heating body 300 generates heat under the action of the alternating magnetic field of the coil body 210, in view of the direct contact between the heating body 300 and the atomizing medium 20, the heat generated by the heating body 300 It is absorbed by the atomizing medium 20 through heat conduction, and finally the atomizing medium 20 is atomized to form an aerosol, which will be carried by the gas in the air intake channel 421 to reach the nozzle mouth 511 through the suction channel 510, and then absorbed by users. When the heating body 300 includes both the electromagnetic induction unit and the infrared radiation unit, the infrared radiation unit will absorb the heat of the electromagnetic induction unit and generate infrared radiation to the atomizing medium 20, so that the atomizing medium 20 can absorb the infrared rays to generate heat. Therefore, part of the heat generated by the heating body 300 is absorbed by the atomizing medium 20 through heat conduction, and another part of the heat generated by the heating body 300 is absorbed by the atomizing medium 20 through heat radiation.

Referring to FIG. 6 , FIG. 7 , FIG. 8 and FIG. 9 , when the atomizing medium 20 is solid, the heating body 300 is fixedly connected to the suction nozzle 500 . For example, the heating body 300 includes a bottom wall 310 and a side wall 320, the bottom wall 310 is spaced apart from the suction nozzle 500 along the axial direction of the suction nozzle 500, that is, the bottom wall 310 is located below the suction nozzle 500, the bottom wall 310 can be arranged horizontally, and the side wall 320 is arranged vertically, and the lower end of the side wall 320 is connected to the periphery of the bottom wall 310 , so that the side wall 320 is arranged around the bottom wall 310 . Both the side wall 320 and the bottom wall 310 together define a heating cavity 330, which is also an open cavity. The upper end of the side wall 320 is fixed on the suction nozzle 500 so that the heating chamber 330 and the suction channel 510 communicate with each other. The heating cavity 330 is used to accommodate the atomizing medium 20 . Since the heating body 300 and the suction nozzle 500 are fixedly connected, the heating body 300 and the suction nozzle 500 can be replaced as a whole. Both the heating body 300 and the suction nozzle 500 may be disposable consumables, and the atomizing medium 20 has been accommodated in the heating body 300 before the heating body 300 and the suction nozzle 500 are connected. When using the heating atomizing device 10, the suction nozzle 500 is inserted in the installation cavity 410, and the heating body 300 containing the atomizing medium 20 will be located in the accommodating cavity 130. Of course, the heating body 300 may not fill the entire accommodating cavity 130, so that the accommodating cavity 130 has a gap 131 between the bottom wall 310 and the bottom plate 110, and a gap 131 between the side wall 320 and the side plate 120. Obviously, The void 131 is not filled by the heating body 300 .

Referring to FIG. 7 , FIG. 8 and FIG. 9 , the heating body 300 is provided with a vent hole 340 , and the vent hole 340 communicates with the heating cavity 330 and the void 131 of the accommodating cavity 130 not filled by the heating body 300 . For example, as shown in FIG. 7 , the ventilation hole 340 may be located on the bottom wall 310 . For another example, as shown in FIG. 10 and FIG. 11 , the vent hole 340 is located on the side wall 320 , and the vent hole 340 may be opened on the side wall 320 at a position close to the suction nozzle 500 . When the user sucks at the mouthpiece 511 , the outside air passes through the air intake channel 421 , the gap 131 of the accommodating cavity 130 , the vent hole 340 , and the heating cavity 330 to reach the inhalation channel 510 . The dotted arrows in Fig. 7 and Fig. 10 represent the gas flow paths. The above-mentioned bottom wall 310 and side wall 320 can form an electromagnetic induction unit. In the case that the heating body 300 only includes an electromagnetic induction unit, in view of the direct contact between the heating body 300 and the atomizing medium 20, the heat generated by the bottom wall 310 and the side wall 320 It is absorbed by the atomizing medium 20 through heat conduction to be atomized. In the case that the heating body 300 includes both the electromagnetic induction unit and the infrared radiation unit, the infrared radiation unit can be attached to the bottom wall 310 and/or the side wall 320, and the infrared radiation unit will absorb the heat of the bottom wall 310 and the side wall 320 and generate The infrared rays radiated toward the atomizing medium 20 allow the atomizing medium 20 to absorb the infrared rays to generate heat. Therefore, part of the heat generated by the heating body 300 is absorbed by the atomizing medium 20 through heat conduction, and another part of the heat generated by the heating body 300 is absorbed by the atomizing medium 20 through heat radiation.

In view of the fact that the heating body 300 is independently installed relative to the pot body 100 and can be replaced, so that the pot body 100 can accommodate both a solid-liquid mixed paste-like atomizing medium 20 and a solid atomizing medium 20, and respectively pass through the corresponding The heating body 300 atomizes it, preventing the phenomenon that the heating and atomizing device 10 can only atomize one kind of atomizing medium 20 , thereby improving the versatility of the heating and atomizing device 10 . The interference of the heating body 300 can also be eliminated, and the inner wall of the pot body 100 can be cleaned conveniently, preventing the condensed matter adhering to the pot body 100 from producing odorous gas during the heating process and affecting the taste of the suction, thereby improving the heating mist User experience of the device 10. The heating body 300 generates heat through the alternating magnetic field of the induction coil body 210 , so that there is no wire between the heating body 300 and the coil body 210 , thereby simplifying the structure of the heating and atomizing device 10 . And based on the special principle of electromagnetic induction heating, the inside and outside of the heating body 300 generate heat at the same time, so that the heating body 300 generates heat and quickly rises to the atomization temperature of the atomization medium 20, avoiding the waiting caused by long preheating time, to ensure that the atomizing medium 20 can be atomized in a short time, and to improve the sensitivity of the heated atomizing device 10 to the suction response. Moreover, when the heating body 300 includes both the electromagnetic induction unit and the infrared radiation unit, the infrared rays generated by the infrared radiation unit can penetrate into the inside of the atomizing medium 20 within a certain range, so that the inner layer and the outer layer of the atomizing medium 20 The layer generates heat at the same time, and then makes the atomizing medium 20 rise to the atomizing temperature for atomization in a short time, which will increase the atomizing speed of the atomizing medium 20 . Infrared rays can evenly cover the atomizing medium 20, so that the atomizing medium 20 is evenly heated and atomized, thereby improving the taste of the pump. Certainly, the infrared rays can pass through the carbonized ashes formed after the atomization of the atomizing medium 20 , effectively preventing the carbonized ashes from being an obstacle to the infrared radiation.

3 and 4, in some embodiments, the heating atomizing device 10 further includes at least one of a first shielding body 610 and a second shielding body 620, and the first shielding body 610 is arranged around the coil body 210, so that the first The shielding body 610 can cover the entire coil body 210 , so that the loss of the alternating magnetic field of the coil body 210 can be prevented, and the utilization rate of the alternating magnetic field of the coil body 210 by the heating body 300 can be improved. The second shielding body 620 is accommodated in the mounting frame 220 and is located in the space between the bottom plate 110 of the pot body 100 and the mounting frame 220. The second shielding body 620 can cover the bottom plate 110, so that it can prevent the crossover in the pot body 100. The variable magnetic field radiates out of the bottom plate 110 . Therefore, under the action of the first shielding body 610 and the second shielding body 620 , the alternating magnetic field is confined in the accommodating cavity 130 , and the utilization rate of the alternating magnetic field by the heating body 300 is improved.

The technical features of the above-mentioned embodiments can be combined arbitrarily. To make the description concise, all possible combinations of the technical features in the above-mentioned embodiments are not described. However, as long as there is no contradiction in the combination of these technical features, should be considered as within the scope of this specification.
