Referring to FIGS. 1 to 4 , the atomizer 10 provided by an embodiment of the present application includes a housing assembly 110 , a liquid inlet member 120 , a liquid guide member 130 , a sealing rubber plug 140 , an upper sealing ring 150 , a lower sealing ring 160 , and a contact electrode 170 , the infrared radiator 200 and the atomizing core 300 . The housing assembly 110 is used to accommodate the liquid inlet member 120 , the liquid guide member 130 , the sealing plug 140 , the upper sealing ring 150 , the lower sealing ring 160 , the contact electrode 170 , the infrared radiator 200 and the atomizing core 300 .

The upper part of the housing assembly 110 is provided with an air intake channel 112 that communicates with the outside world, and the lower part of the housing assembly 110 is provided with an air intake channel 111 that communicates with the outside world. The upper sealing ring 150 is pressed between the liquid inlet 120 and the housing assembly 110 , so that the lumen 121 of the liquid inlet 120 is communicated with the suction channel 112 . A liquid storage chamber 113 is formed between the housing assembly 110 , the liquid inlet 120 and the sealing rubber plug 140 . The liquid storage chamber 113 is used to store liquid atomization medium, and the atomization medium can be an aerosol generating matrix such as oil. The upper sealing ring 150 can play a sealing role to prevent the liquid storage chamber 113 from communicating with the suction channel 112 and the lumen 121 of the liquid inlet 120, and prevent the atomization medium in the liquid storage chamber 113 from flowing into the suction channel 112 and the liquid inlet. within the lumen 121 of the member 120 . The lower end of the liquid inlet member 120 is also fixed on the casing assembly 110 , the lower sealing ring 160 is pressed between the lower end of the liquid inlet member 120 and the casing assembly 110 , and the lower sealing ring 160 acts to seal the lumen 121 of the liquid inlet member 120 . The lower end of the lumen 121 of the liquid inlet member 120 and the air inlet passage 111 are in airtight communication with each other.

The liquid guiding member 130 can be made of cotton material, and the liquid guiding member 130 can also be a tubular structure. Containment. The liquid inlet 120 and the liquid guiding member 130 are provided with a liquid inlet hole, and the liquid inlet hole and the liquid storage cavity 113 are communicated with each other, so that the atomized medium in the liquid storage cavity 113 can flow into the liquid inlet through the liquid inlet hole. inside the liquid part 130 . Since the liquid guiding member 130 is made of cotton material, the liquid guiding member 130 can transmit and buffer the atomized medium flowing out from the liquid inlet hole.

In some embodiments, the atomizing core 300 includes a central portion 330 that can be a rod-shaped structure, and the central portion 330 can be made of a porous ceramic material, so that the central portion 330 has a large number of micropores inside to form a certain porosity , through the action of the micro-holes, the central part 330 can have the function of transmitting and buffering the atomized medium. The center portion 330 has an outer peripheral surface 331 that forms an atomizing surface 320 for atomizing the atomizing medium. The central portion 330 can be in contact with the liquid guiding member 130 . When the liquid in the liquid storage chamber 113 enters the liquid guiding member 130 through the liquid inlet hole of the liquid feeding member 120 , the central portion 330 will atomize the medium in the liquid guiding member 130 . Playing the role of absorption, the atomization medium penetrates into the center portion 330 from the liquid guide member 130 and reaches the outer peripheral surface 331 serving as the atomization surface 320 . The cross-sectional dimension of the central portion 330 may be 2 mm to 4 mm.

The infrared radiator 200 can be made of metal, heat-generating ceramic or conductive infrared material. The infrared radiator 200 includes an annular sleeve, the central axis of the annular sleeve may be a straight line, and the cross-sectional dimension of the annular sleeve may be 4 mm to 8 mm. The contact electrode 170 passes through the lower part of the housing assembly 110 , and the contact electrode 170 is electrically connected to the infrared radiator 200 , so that the contact electrode 170 can transmit current to the infrared radiator 200 . The infrared radiator 200 is connected to the housing assembly 110 and is spaced apart from the outer peripheral surface 331 as the atomizing surface 320, thereby effectively preventing the infrared radiating body 200 from directly adhering to the atomizing surface 320. Obviously, the atomizing surface 320 and the infrared radiating body There are spacing gaps 310 between 200 . The central portion 330 is penetrated in the cavity of the annular sleeve, and it can be understood that the space 310 is actually a part of the cavity of the annular sleeve. When the contact electrode 170 transmits current to the infrared radiator 200, the infrared radiator 200 will generate heat and radiate to the outer peripheral surface 331 by means of infrared rays. When the atomizing medium on the outer peripheral surface 331 absorbs the heat, it rises to atomization At this temperature, the atomizing medium will atomize to form an aerosol.

When the user inhales at the end of the inhalation channel 112 , the outside air will enter the spacer gap 310 from the air intake channel 111 through the lower end of the lumen 121 of the liquid inlet 120 , so that the outside air will carry the air in the spacer space 310 The aerosol enters the suction channel 112 through the upper end of the lumen 121 of the liquid inlet member 120, so that the aerosol entering the suction channel 112 is absorbed by the user. The dotted arrow in Figure 1 is the flow trajectory of the gas.

The atomizer 10 may further include a reflector 181 and a heat insulator 182 , the reflector 181 is arranged around the infrared radiator 200 , and the heat insulator 182 is arranged around the reflector 181 . The heat of the infrared radiator 200 is completely transferred to the outer peripheral surface 331 of the central portion 330 , so as to prevent the heat loss of the infrared radiator 200 and improve the utilization rate of heat. Further, the heat insulator 182 further prevents the heat from being transmitted to the casing, on the one hand, preventing the casing from being hot and uncomfortable to the user due to the high temperature during the operation of the atomizer 10, and on the other hand, it can also improve the infrared radiator 200. heat utilization.

If the atomizer 10 adopts the design mode in which the heating resistance wire is directly attached to the atomizing surface 320, for this design mode, the heating resistance wire is energized to generate heat, and the heat is penetrated to the atomizing surface 320 by heat conduction, and the atomizing surface is energized. The atomizing medium on the 320 absorbs the heat of the heating resistance wire and atomizes to form an aerosol, but this design mode has at least the following defects:

First, the heat is transmitted through heat conduction, so that the opportunities for each area on the atomizing surface 320 to absorb heat are not equal, so the heat is distributed unevenly on the atomizing surface 320, for example, the area on the atomizing surface 320 close to the heating resistance wire absorbs heat There is a lot of heat to form a high temperature area with a higher temperature. The atomization medium located in the high temperature area will be scorched due to the high temperature, resulting in a burnt smell in the aerosol, which affects the user's suction taste. At the same time, the area away from the heating resistance wire absorbs less heat and forms a low temperature area with a lower temperature. The atomization medium located in the low temperature area will not be fully atomized because the temperature is too low, making the atomized particles in the aerosol larger. affect the taste of suction. Of course, the temperature in the low temperature region cannot even reach the atomization temperature and cannot atomize the atomizing medium, which reduces the amount of atomization of the atomizing medium per unit time, resulting in a low aerosol concentration.

Second, the heating resistance wire is usually made of heavy metal materials. During the working process of the heating resistance wire, the heating resistance wire will produce a series of physical and chemical reactions with the atomizing medium attached to it at high temperature, so that the heavy metal elements enter the aerosol. It will be absorbed by the user, which will damage the health of the user, resulting in the safety risk of the entire atomizer 10 . At the same time, the atomizing medium attached to the heating resistance wire will absorb heat during the atomization process, which will cause the temperature of the heating resistance wire to decrease. Therefore, the heating resistance wire has temperature fluctuations during operation, which will also affect the suction of aerosol. Taste.

The third is that there are two sources for the generation of aerosols, one is the area where the heating resistance wire is not set on the atomizing surface 320, this area is recorded as the atomizing area of the atomizing surface 320, and the atomizing medium in the atomizing area The higher the supply, the more aerosols are formed. The other is the surface area of the heating resistance wire. Since the heating resistance wire is usually made of dense metal or alloy material, the penetration and transmission capacity of the heating resistance wire to the atomizing medium is lower than that of the atomizing core 300, so the fog in this surface area is The supply of the atomizing medium is less and less aerosol is formed. In fact, the aerosol generated by the atomizing medium on the surface area of the heating resistance wire is negligible compared to the aerosol generated by the atomizing medium on the atomizing area of the atomizing surface 320 Excluding. Therefore, the heating resistance wire occupies a considerable part of the atomization surface 320, so that the effective area of the atomization area is smaller than the total area of the atomization surface 320, and finally the atomization amount of the atomization medium per unit time is difficult to increase and affects the gas the concentration of the sol.

Fourth, part of the heat of the heating resistance wire will be transferred to the area outside the atomizing surface 320, thereby reducing the utilization rate of the heat of the heating resistance wire, thereby affecting the atomization amount and aerosol concentration of the atomizing medium per unit time.

For the atomizer 10 of the above-mentioned embodiment, since the infrared radiator 200 is arranged around the outer peripheral surface 331 serving as the atomizing surface 320, and there is a gap 310 between the infrared radiator 200 and the atomizing surface 320 due to the interval, so The infrared radiator 200 is effectively prevented from directly adhering to the atomizing surface 320 . In this way, at least the following beneficial effects can be formed:

First, in view of the fact that the infrared radiator 200 and the atomizing surface 320 are spaced apart and do not occupy part of the atomizing surface 320, the total area of the atomizing surface 320 is the effective area of the atomizing area, thereby making the atomizing area effective. The area is greatly increased, thereby increasing the atomization amount of the atomized medium and the concentration of the aerosol per unit time, and ultimately improving the user experience. At the same time, the atomizing surface 320 is a curved surface structure. Compared with the atomizing surface 320 of the same area and in a flat state, the atomizing surface 320 is actually in a winding state, so that the installation space occupied by the atomizing surface 320 is greatly reduced. , thereby making the atomizer 10 more compact in structure.

Second, the infrared radiator 200 will not be in direct contact with the atomizing medium on the atomizing surface 320, which prevents the infrared radiator 200 from producing physical and chemical reactions with the atomizing medium at high temperatures, and prevents heavy metal elements in the infrared radiator 200 from entering the gas. The sol can be absorbed by the user to improve the safety of the atomizer 10 in use. At the same time, the atomization medium is separated from the infrared radiator 200 to prevent the atomization medium from absorbing heat during atomization and reducing the temperature of the infrared radiator 200, avoiding fluctuations in the temperature of the infrared radiator 200, and ensuring that the temperature of the infrared radiator 200 is always maintained Consistent to improve the suction taste of the aerosol.

Third, the heat on the infrared radiator 200 is transmitted to the atomizing surface 320 by infrared radiation. Compared with the way of heat conduction, each area on the atomizing surface 320 has a more equal chance of absorbing heat, ensuring that the heat is evenly distributed in the On the atomizing surface 320, the temperature on the atomizing surface 320 is kept consistent, preventing local high temperature and local low temperature from appearing on the atomizing surface 320, thereby avoiding the generation of burnt smell and large particles that affect the suction taste.

Fourth, by setting the reflector 181 and the heat insulator 182, most of the heat generated by the infrared radiator 200 is absorbed by the atomizing surface 320, preventing the heat from radiating to the space outside the atomizing surface 320 and affecting the utilization rate of energy , to increase the atomization amount and aerosol concentration of the atomization medium per unit time.

The interval gap 310 between the infrared radiator 200 and the outer peripheral surface 331 is denoted as the first gap 311, and the cross-sectional dimension H1 of the first gap 311 is equal everywhere, so that the almost uniformity of the heat absorbed by the outer peripheral surface 331 can be further improved, and the The uniformity of heat distribution on the outer peripheral surface 331 prevents local high temperature on the outer peripheral surface 331 . The value range of the cross-sectional dimension H1 of the first gap 311 may be 0.5 mm to 3.0 mm, and the specific value thereof may be 0.5 mm, 2.5 mm, or 3 mm.

In some embodiments, the atomizing core 300 further includes an edge portion 340 , and the edge portion 340 includes a top plate 341 and a side barrel 342 . The top plate 341 is connected with the end of the side barrel 342, and the cross-sectional size of the side barrel 342 may be 6 mm to 12 mm. The central portion 330 is fixed on the top plate 341 and is located in the space enclosed by the top plate 341 and the side cylinders 342 . The side tube 342 has an inner peripheral surface 342 a provided around the center portion 330 . A receiving cavity 350 is formed between the edge portion 340 and the central portion 330 , the inner peripheral surface 342 a and the outer peripheral surface 331 define a part of the boundary of the receiving cavity 350 , and the infrared radiator 200 is at least partially located in the receiving cavity 350 and is spaced from the inner peripheral surface 342 a It is arranged that the outer peripheral surface 331 also forms an atomizing surface 320 for atomizing the atomizing medium. At this time, the atomizing surface 320 includes both the outer peripheral surface 331 and the inner peripheral surface 342a. The top plate 341 is provided with an air guide hole 341 a , and the air guide hole 341 a communicates with the accommodating cavity 350 and the lumen 121 of the liquid inlet 120 . The space gap 310 between the inner peripheral surface 342a and the infrared radiator 200 is denoted as the second gap 312 , the cross-sectional dimension H2 of the second gap 312 is equal everywhere, and the cross-sectional dimension H1 of the first gap 311 and the second gap 312 The cross-sectional dimension H2 is also equal. Meanwhile, the infrared radiator 200 is spaced apart from the outer peripheral surface 331 and the inner peripheral surface 342a by an equal distance, respectively.

Since the infrared radiator 200 is accommodated in the accommodating cavity 350 defined by the inner peripheral surface 342a and the outer peripheral surface 331, the atomizing medium on the inner peripheral surface 342a and the outer peripheral surface 331 simultaneously receives the heat of the infrared radiator 200 and is atomized. That is, the atomizing surface 320 includes an outer peripheral surface 331 and an inner peripheral surface 342a, which can further increase the total area of the atomizing surface 320, thereby increasing the atomization amount and aerosol concentration of the atomizing medium per unit time. At the same time, the infrared radiator 200 can be regarded as being sandwiched between the outer peripheral surface 331 and the inner peripheral surface 342a, which effectively prevents the infrared radiator 200 from radiating heat to the space outside the receiving cavity 350, so that the heat radiated by the infrared radiator 200 is prevented. Most of it is absorbed by the outer peripheral surface 331 and the inner peripheral surface 342a, which improves the utilization rate of the heat of the infrared radiator 200. Moreover, the arrangement of the reflector 181 and the heat insulator 182 can also be omitted, so as to simplify the structure of the atomizer 10 . Since the cross-sectional dimensions of the first void 311 and the second void 312 are equal, the temperatures on the inner peripheral surface 342 a and the outer peripheral surface 331 can be kept the same, so that the gas generated on the inner peripheral surface 342 a and the outer peripheral surface 331 can be The size of the particulate matter contained in the aerosol is equal to ensure the suction taste of the aerosol.

In some embodiments, the central axes of the spacing gap 310 , the lumen 121 of the liquid inlet 120 , the air intake channel 111 and the air intake channel 112 are straight lines that coincide with each other. Therefore, when the user inhales, the flow trajectory of the aerosol carried by the external gas is almost a straight line, which prevents the aerosol from generating eddy currents due to the curved flow trajectory, reduces the collision chance between small particles, and reduces the collision and combination of small particles in the aerosol. The proportion of large particulate matter is formed to avoid the influence of large particulate matter on the suction taste, and to improve the user's suction experience.

In some embodiments, the operating phase of the infrared radiator 200 includes a start-up phase and an atomization phase, the atomization phase being located after the start-up phase. The activation temperature of the infrared radiator 200 in the activation stage is greater than the atomization temperature in the atomization stage. For example, the start-up temperature is 350°C to 700°C, and the atomization temperature is 300°C to 350°C. The duration of the startup phase is 0.1s to 0.2s. In view of the separation of the infrared radiator 200 from the atomization medium, setting a relatively high start-up temperature can effectively shorten the time required for the atomization medium to rise to the atomization temperature, so as to improve the atomization speed of the atomization medium and the pairing of the atomizer 10 Puff Response Sensitivity.

The present application also provides an electronic atomization device, the electronic atomization device includes a power supply assembly and an atomizer 10 , and a battery of the power supply assembly supplies power to the infrared radiator 200 . The atomizer 10 can be detachably connected with the power supply assembly. When the atomizing medium in the atomizer 10 is consumed, the atomizer 10 can be unloaded and discarded from the power supply assembly, and then a new container can be installed on the power supply assembly. The atomizer 10 is full of atomizing medium, so the power supply components can be recycled, and the atomizer 10 is a disposable consumable. In other embodiments, the atomizing medium can be injected into the liquid storage chamber 113 so that the atomizer 10 can be recycled. Of course, the atomizer 10 can also form a non-detachable connection relationship with the power supply assembly.

The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity, all possible combinations of the technical features in the above-described embodiments are not described. However, as long as there is no contradiction between the combinations of these technical features, All should be regarded as the scope described in this specification.

It should be pointed out that for those skilled in the art, without departing from the concept of the present application, several modifications and improvements can be made, which all belong to the protection scope of the present application.
