Background technique

Inhalable devices typically include a nebulizer and a power supply. The nebuliser can heat the liquid nebulizable base by means of nebulization, so that it can generate nebulized gas for the user to inhale. The power supply device is used to supply power to the atomizer. The atomizing core of the existing atomizer usually includes a heating wire and a liquid absorbing part wrapped outside the heating wire.

The first liquid guiding part 221 includes a first side 2211 and a second side 2212 opposite to each other. The two second liquid guiding parts 222 are respectively connected to the first side 2211 and the second side 2212 of the first liquid guiding part 221 , and extend out of the accommodating cavity S through the first groove 211 and connect to the liquid storage component 40 . The two second liquid guiding parts 222 are stacked on top of each other, and the surfaces of the two second liquid guiding parts 222 away from each other serve as the contact surface 2220 where the second liquid guiding part 222 contacts the liquid storage part 40 , so that the liquid stored in the liquid storage part 40 The atomizable substance can be guided or transported to the first liquid guiding part 221 in the core shell 21 through the above-mentioned contact surface 2220 . The heater 23 is located in the accommodating chamber S and contacts the inner surface of the first liquid guiding part 221 . In some embodiments, the material of the core shell 21 may be polycarbonate (PC) which can resist strong impact.

In this way, when the aerosolizable substance stored in the liquid storage part 40 is guided or transported to the first liquid guide part 221 inside the core shell 21 through the second liquid guide part 222 of the liquid guide part 22, the The heater 23 on the inner surface of the part 221 can start to heat the nebulizable substrate in the first liquid guiding part 221, so as to obtain an aerosol that can be inhaled by the user. In a specific embodiment of the present application, a flat liquid-guiding member 22 can be bent at a middle position to obtain the first liquid-guiding part 221 , and the parts at both ends form the second liquid-guiding part 222 . In some embodiments, the first groove 211 can be opened from the upper end of the core shell 21 away from the base member 10 toward the lower end of the base member 10 , and the first groove 211 does not penetrate through the lower end of the core shell 21 .

As shown in FIG. 2 and FIG. 3 , in some embodiments, a second groove 212 communicating with the accommodating chamber S may also be provided on the core shell 21 . The first liquid guide part 221 also communicates with the liquid storage part 40 through the second groove 212 , so that the aerosolizable substance stored in the liquid storage part 40 can also be delivered to the first liquid guide part 221 through the second groove 212 . That is, the atomizable substrate stored in the liquid storage part 40 can not only be delivered to the first liquid guide part 221 in the core shell 21 through the first groove 211, but the second groove 212 is used as a liquid inlet tank, so that the liquid storage part The aerosolizable substance stored in 40 can also be delivered to the first liquid guiding part 221 through the second tank 212 . In some embodiments, the second slot 212 can be opened between the upper end and the lower end of the core shell 21 , and the surface area of the second slot 212 is smaller than that of the first slot 211 .

In the prior art, the liquid-guiding component includes a first circle of liquid-guiding cotton arranged in the core shell and a second circle of liquid-guiding cotton covered outside the core shell. The second circle of oil-guiding cotton is connected to the liquid storage chamber, and the liquid The liquid is conveyed along the second circle of oil-guiding cotton, the liquid inlet groove opened on the core shell and the first circle of oil-guiding cotton. In this application, the second circle of oil-guiding cotton provided on the outer ring of the core shell in the prior art is subtracted and the liquid-guiding part 22 is set to include a first liquid-guiding part 221 and a second liquid-guiding part 222, and the second liquid-guiding part 222 passes through The first groove 211 protrudes from the core shell 21 and is connected to the liquid storage part 40, so that the aerosolizable substance stored in the liquid storage part 40 can be transported to the first liquid guide part in the core shell 21 through the second liquid guide part 222 221 in. Moreover, because the application subtracts the second circle of oil-guiding cotton located on the outer ring of the core shell in the prior art, the liquid-guiding path becomes shorter, which is beneficial to the utilization rate of the atomizable substrate in the liquid-guiding member 22, and improves the maximum yield of the product. Number of mouths. It can be understood that, on the premise that the liquid storage part 40 stores a relatively large amount of nebulizable substrate, even if the single method of transporting from the liquid storage part 40 to the first liquid guide part 222 through the second liquid guide part 222 is adopted, it can also ensure The liquid guiding member 22 is constantly filled with sufficient liquid.

Furthermore, when the core shell 21 is also provided with the second groove 212, the aerosolizable substrate stored in the liquid storage part 40 can also be transported to the first liquid guide part 221 through the second groove 212, which improves the efficiency from the storage. The liquid guide volume from the liquid part 40 to the first liquid guide part 221 makes the liquid guide part 22 have sufficient liquid continuously, and can withstand the high temperature (usually exceeding 300 degrees Celsius) generated by the heater 23 during the atomization process.

Among them, the first layer 2201 is the closest to the heater 23 in the liquid guide part 22, that is, the longitudinal flow velocity of the atomizable substrate is greater than the lateral flow velocity, thereby increasing the content of the atomizable substrate in the first layer 2201, so that the liquid guide The part of the component 22 closest to the heater 23 has sufficient liquid to withstand the high temperature generated by the heater 23 during the atomization process.

Except for the first layer 2201 closest to the heater 23 in the liquid guiding part 22, other layers in the liquid guiding part 22 can be stacked in any order. In some embodiments, the part farthest from the heater 23 in the liquid guiding part 22 is the second layer 2202 whose grain direction is perpendicular to the central axis O of the first channel 2210, so that the part of the liquid guiding part 22 farthest from the heater 23 has Longitudinal liquid-locking ability prevents the risk of leakage caused by the aerosolizable matrix going down.

In some specific embodiments, the liquid guiding component 22 may be liquid guiding cotton, the first layer 2201 of the liquid guiding component 22 is linen cotton, and the second layer 2202 is wood pulp cotton.

Moreover, the first layer 2201 of the liquid guiding part 22 closest to the heater 23 is provided with the grain direction parallel to the central axis O of the first flow channel 2210, so that the part of the liquid guiding part 22 closest to the heater 23 can withstand The high temperature generated by the heater 23 during the atomization process further avoids burning the core.

In some embodiments, the heater 23 may be a heating mesh. Compared with heating wire, the contact area between the heating mesh and the atomizable substrate is larger, which makes the heating more uniform. Moreover, compared with the heating wire, the heating mesh has a smaller resistance variation. In some specific embodiments, the material of the heating mesh can be stainless steel.

In some other embodiments, the heater 23 may further include two heating nets, and the two heating nets are stacked along a direction perpendicular to the central axis O of the first flow channel 2210 . By arranging two heating nets, the uniformity of heating can be further improved.

Example 1

The outer diameter of the liquid storage cotton is 17mm, the inner diameter is 5mm, and the height is 36.5mm. The porosity of the liquid storage member is 4.5%. The density of the catheter cotton is 70g/cm ³ . The fluid-conducting cotton includes a layer of vertical linen cotton with a density of 70g/cm ³ and a layer of horizontal grain wood pulp cotton with a density of 70g/cm ³ (referred to as the structure of the fluid-conducting cotton: 1+1). near a heater.

Embodiment 2-3 and comparative example 1-2

The difference from Example 1 lies in the number of layers of cross-grain wood pulp cotton, see Table 1 for details.

The atomizers of Examples 1-3 and Comparative Examples 1-2 were assembled into electronic cigarette samples, and the target number of puffs and the maximum number of puffs were tested for each sample. The testing instrument used was ZZ-DZ11 electronic cigarette smoking machine (The requirements of the UL8139 standard are implemented, Zhongzhou Measurement and Control (Shenzhen) Co., Ltd.), the test index is the number of suction ports, and the standard for the number of ports is: the instrument sucks for 2 seconds and stops for 20 seconds, which is recorded as 1 port. The test results are recorded in Table 1. Among them, the test procedure of the target number of puffs is: assuming that the preset number of puffs (that is, the service life) of the electronic cigarette is 500 puffs, that is, the user can smoke the electronic cigarette 500 times without dry burning; then, set the target puff number 500, then use the above-mentioned instrument to start testing the sample; when the instrument finishes the 500-port test, remove the sample from the instrument, check the appearance of the sample and the interior of the atomization component and confirm whether the sample has been dry-burned; When it is burned, it is qualified, otherwise it is unqualified. The test procedure of the maximum number of mouths is basically the same as that of the target number of mouths. The difference is that there is no need to set the target number of mouths. Instead, the test will not be stopped until the sample is dry-burned or other failures make the suction operation unable to continue. At this time, record the obtained The number of mouths is the maximum number of mouths of the sample.

From the results in Table 1, it can be seen that when the size and porosity of the oil storage cotton and the density of the oil-conducting cotton meet certain conditions, setting the oil-conducting cotton with a suitable number of layers of cross-grain wood cotton can prevent the sample from dry burning. Compared with Examples 1-3, when the number of layers of the horizontal-grain wood cotton in Comparative Example 1-2 is too many, the sample is prone to dry burning when the 500-mouth test is completed. Wherein, in Example 3, when the number of layers of the horizontal-grain wood cotton is 3 layers, the sample has the largest number of openings.

Embodiment 4-16 and comparative example 3-4

The difference from Example 1 lies in the porosity of the oil storage cotton, see Table 2 for details.

Table 2

From the results in Table 2, it can be seen that when the size of the oil storage cotton and the density and structural composition of the oil-conducting cotton meet specific conditions, setting the oil storage cotton to have a suitable porosity can avoid dry burning of the sample and make the sample have a higher maximum Number of mouths. Compared with Examples 1, 4-16, the porosity of the oil storage cotton in Comparative Example 3 is too small, resulting in the oil locking speed being greater than the oil delivery speed, dry burning is prone to occur when the sample completes the 500-port test, and the suction resistance of Comparative Example 3 is too high. Larger, resulting in a smaller maximum number of ports; the porosity of the oil storage cotton in Comparative Example 4 is too large, causing the oil locking speed to be lower than the oil delivery speed, and the phenomenon of sucking e-liquid is prone to occur, and the maximum number of ports is small. Among them, in Examples 1 and 5-10, when the porosity of the oil storage cotton is 4% to 5%, the maximum number of openings of the samples is relatively high.

Embodiment 17 and Comparative Examples 5-8

The difference from Example 1 lies in the density of the oil-conducting cotton, see Table 3 for details.
