Referring to FIG. 3 , FIG. 4 and FIG. 5 , in some embodiments, the support body 100 includes a housing 110 , a fixing frame 120 , a first pressing cover 130 and a second pressing cover 140 . Both the housing 110 and the fixing frame 120 can be approximately cylindrical in shape, and the fixing frame 120 and the reflector 400 are accommodated in the housing 110, so that the housing 110 is sleeved on the fixing frame 120 and the reflector 400, that is, the housing 110 surrounds the fixing frame 120 and reflector 400 are set. The fixed frame 120 is sleeved on the pot body 200, that is, the fixed frame 120 is arranged around the pot body 200, and the lower end of the fixed frame 120 abuts against the reflector 400, and the reflector 400 plays a role of limiting and supporting the installation of the fixed frame 120. The fixing frame 120 can be made of heat insulating material, so as to effectively prevent the heat on the pot body 200 from being conducted to the shell 110 through the fixing frame 120 . The first gland 130 is located on the upper end of the casing 110 , and the first gland 130 presses between the pot body 200 and the casing 110 , so as to seal the gap between the pot body 200 and the casing 110 . The second pressing cover 140 is pressed between the lower end of the housing 110 and the reflector 400 , so as to seal the gap between the reflector 400 and the housing.

Referring to Fig. 3, Fig. 4 and Fig. 5, in some embodiments, the pot body 200 includes a side pipe 210, an end cover 220 and a protruding ring 230, the side pipe 210 can be approximately in the shape of a circular tube, and the end cap 220 can be approximately in the shape of a flat plate structure, the end cap 220 is connected to the lower end of the side pipe 210 , so that the end cap 220 closes the lumen of the side pipe 210 to form a heating cavity 240 for accommodating the atomized substrate 20 . The protruding ring 230 is roughly circular, and the protruding ring 230 is connected to the upper end of the side pipe 210. The protruding ring 230 is located outside the heating chamber 240. The protruding ring 230 is opposite to the side pipe along the axial direction (ie radial direction) perpendicular to the side pipe 210. 210 protrudes a certain length, that is, the protruding ring 230 is protrudingly connected with the side pipe 210, and the protruding ring 230 can abut against the first gland 130 on the support body 100, so that the first gland 130 exerts pressure on the protruding ring 230 from below. upward support. Through the abutment of the protruding ring 230 and the first gland 130 , the installation of the pot body 200 can be axially positioned. The pot body 200 forms a detachable connection relationship with the fixing frame 120 and the first pressing cover 130, so that the pot body 200 can be unloaded from the supporting body 100 for replacement. The pot body 200 may be made of materials capable of penetrating infrared rays, for example, the pot body 200 is made of quartz material. After the infrared rays penetrate the pot body 200 and enter the heating chamber 240, the atomizing substrate 20 can absorb the infrared rays and generate heat to atomize to form an aerosol.

In some embodiments, along the axial direction of the pot body 200 (that is, the vertical direction), the infrared heating body 310 is spaced apart from the pot body 200, so that there is a certain gap between the infrared heating body 310 and the end cover 220, that is, the infrared heating body 310 and the end cover 220 have a certain gap. The heating body 310 is located under the end cover 220 to ensure that the infrared heating body 310 and the end cover 220 maintain a non-contact relationship. The orthographic projection of the infrared heating body 310 along the vertical direction may all fall on the end cover 220 . The infrared heating body 310 is roughly in the shape of a line, for example, the infrared heating body 310 is wound to form a constant velocity helix structure. The electrode body 320 has a roughly columnar structure, the electrode body 320 is installed on the reflector 400, the upper end of the electrode body 320 is electrically connected to the infrared heating body 310, and the lower end of the electrode body 320 is electrically connected to the power supply, so that the power supply can pass through the electrode body 320 supplies power to the infrared heating body 310 . The number of electrode bodies 320 is two, and the two electrode bodies 320 are electrically connected to the two ends of the infrared heating body 310 respectively. , and the two electrode bodies 320 are located on the side of the infrared heating body 310 away from the end cap 220 , so that the two electrode bodies 320 extend toward the side of the infrared heating body 310 away from the end cap 220 .

The infrared heater 310 can convert electrical energy into heat energy and generate infrared rays, so that the heat generated by the infrared heater 310 enters the heating chamber 240 through the end cover 220 in the form of infrared radiation to be absorbed by the atomized substrate 20 . Since the end cover 220 is located at the lower end of the pot body 200, and infrared rays enter the heating chamber 240 through the end cover 220, it can be understood that the infrared heater 310 heats the bottom of the pot body 200 to form a "bottom heating" mode.

Referring to Fig. 3, Fig. 4 and Fig. 5, in some embodiments, the reflector 400 and the infrared heating body 310 are vertically spaced apart, so that the reflector 400 is located below the infrared heating body 310, and the infrared heating body 310 and the reflector There is a certain gap between the bodies 400 to maintain a non-contact relationship. Obviously, the pot body 200 , the infrared heating body 310 and the reflector 400 are arranged at intervals along the vertical direction, and the infrared heating body 310 is located between the pot body 200 and the reflector 400 . The reflector 400 includes a support cylinder 410 and a concave portion 420 , the support cylinder 410 may be substantially cylindrical, and the housing 110 is sleeved on the support cylinder 410 . The recessed part 420 is connected to the upper end of the support tube 410 , and the recessed part 420 is recessed downward to a certain depth, so that the recessed part 420 is located in the cylinder cavity of the support tube 410 and closes the upper end of the cylinder cavity. The reflective surface 421 is located on the recessed portion 420 , and the electrode body 320 passes through the recessed portion 420 , and the part of the electrode body 320 below the recessed portion 420 can be at least partially accommodated in the cylinder cavity of the supporting cylinder 410 . The reflective surface 421 can be a concave surface, and the concave surface can be a concave spherical surface. From the edge of the reflective surface 421 to the center of the reflective surface 421, the distance H from the reflective surface 421 to the infrared heating body 310 increases; the infrared heating body 310 along the vertical direction The orthographic projection can all fall on the reflective surface 421, so that the reflective surface 421 can form a concave mirror reflection on the infrared rays emitted by the infrared heating element 310, so that all the infrared rays reflected by the reflective surface 421 are gathered on the end cover 220 Within the coverage area, ensure that all the infrared rays emitted by the infrared heater 310 can pass through the end cover 220 and enter the heating chamber 240, thereby improving the utilization rate of infrared rays and finally improving the utilization rate of heat generated by the infrared heater 310. Obviously, the atomized substrate 20 absorbs more infrared rays and heat per unit time, so that the atomized substrate 20 can be heated to the atomization temperature in a shorter time, thereby increasing the atomization speed of the atomized substrate 20.

When working, the electrode body 320 supplies power to the infrared heating body 310, and the infrared heating body 310 converts electrical energy into heat and generates infrared rays, so that the heat enters the heating chamber 240 through the end cover 220 through infrared radiation. At this time, the atomization The substrate 20 will absorb infrared rays and generate heat to atomize to form an aerosol. Therefore, the atomized substrate 20 does not directly contact the infrared heating body 310 , so that the infrared heating body 310 heats the atomized substrate 20 in a non-contact manner. Through the non-contact heating of the infrared heating body 310, at least the following beneficial effects can be formed:

One is that infrared rays have good penetration. Infrared rays can penetrate the atomized substrate 20 and reach a certain depth, so that the atomized substrate 20 within this depth range absorbs heat and generates temperature at the same time. Obviously, the atomized substrate 20 within this depth range The inner layer and the surface layer heat up at the same time, so that on the one hand, it can ensure that the inner layer and the surface layer absorb heat and heat up at the same time, avoiding the phenomenon that the inner layer and the surface layer absorb heat and heat up successively, so that the atomization substrate 20 quickly rises to The atomization temperature reduces the preheating waiting time of the atomizing substrate 20 and increases the atomization speed of the atomizing substrate 20, and the preheating waiting time can be shortened to less than 10 seconds. On the other hand, it can ensure that the inner layer and the surface layer are raised to the same atomization temperature at the same time, avoiding the formation of a temperature gradient between the inner layer and the surface layer, so that the particle size of the aerosol particles formed by the atomization of the inner layer and the surface layer at the same temperature is the same , to ensure that the inner layer and the surface layer are evenly heated and atomized to form a consistent inhalation taste of the aerosol, thereby improving the user's inhalation experience. And it can also effectively avoid the dry burning phenomenon caused by the high temperature of the outer layer, prevent the burnt smell and irritating gas produced by dry burning, and further improve the user's suction experience.

The second is that infrared rays can well penetrate the carbonized ash formed after the atomization of the atomization matrix 20, so that the atomization matrix 20 covered by the carbonization ash can effectively absorb infrared rays and completely atomize, so as to avoid the impact of the carbonization ash on the heat transmitted by heat conduction. The resulting blocking and loss effects prevent the atomization substrate 20 covered by carbonized ash from being completely atomized, thereby improving the utilization rate of the atomization substrate 20 . At the same time, if the heat transmitted by heat conduction, with the consumption of the atomized substrate 20, the thickness of the carbonized ash will increase and the distance between the heating body will increase. In view of the loss of heat caused by the carbonized ash and long-distance transmission, For the previous suction, there will be more heat conduction to the atomized base 20, so that more atomized base 20 is atomized to form an aerosol, so the concentration of the aerosol sucked earlier is larger; If the pumping is performed, there will be less heat conduction to the atomized base 20, and there will be less atomized base 20 atomized to form an aerosol, so the concentration of the aerosol drawn earlier is lower. In short, there is a noticeable difference in mouthfeel between the first few puffs and the last few puffs. In view of the fact that infrared rays can eliminate the influence of distance and the thickness of carbonized ash, during each inhalation process of the user, there will be the same amount of infrared rays absorbed by the atomization base 20, so that the same amount of atomization base 20 will be atomized, ensuring the user's The aerosol concentration is consistent from puff to puff to enhance the puffing experience.

The third is to prevent the direct contact between the atomizing substrate 20 and the infrared heating body 310, avoiding the dirt generated by the atomizing substrate 20 in the atomization process from adhering to the infrared heating body 310, preventing the contamination of the infrared heating body 310 by dirt, and improving The cleanliness of the infrared heating body 310 also prevents dirt from affecting the suction experience due to the generation of odorous gas under the action of heat. At the same time, it is also possible to prevent dirt from affecting the heating uniformity of the infrared heating element 310 due to heat absorption.

Fourth, the pot body 200 is detachably connected to the support body 100, so that the pot body 200 can be replaced. When the pot body 200 has dirt, a new pot body 200 can be replaced to improve the cleanliness of the pot body 200 and prevent dirt from being heated. Odor gas is produced and affects the taste of smoking.
