In the description of the present application, the meaning of "multiple" is two or more, unless otherwise specifically limited.
[0028] Please refer to Figures 1-5 The embodiment of the present application provides an atomizing bullet, which comprises a suction nozzle piece 1, a flexible piece 2 and a cup body 3 with an opening at one end, wherein the suction nozzle piece 1 is fixedly connected to the opening end of the cup body 3 through the flexible piece 2, a spiral airway 4 is formed between the flexible piece 2 and the cup body 3, an air inlet 11 and an air outlet 132 are provided on the suction nozzle piece 1, the air inlet 11 communicates with the air inlet end of the spiral airway 4, and the cup body 3 defines an atomization channel 31 which communicates with the air outlet 132 and the outlet end of the spiral airway 4.
[0029] In this embodiment of the invention, the nozzle 1 is fixed to the open end of the cup body 3 by the flexible member 2. The cup body 3 can be used to contain the atomizing medium. Therefore, when the cup body 3 is used for heating, atomized gas can be formed on the cup body 3. In addition, an air inlet 11 communicating with the outside is provided on the nozzle 1, and a spiral air passage 4 communicating with the air inlet 11 is also formed between the flexible member 2 and the cup body 3. Therefore, the airflow can flow from the air inlet 11 to the spiral air passage 4 and then to the atomization channel 31 of the cup body 3, and finally be discharged through the air outlet 132, carrying away the atomized gas formed in the cup body 3. Therefore, the atomizing bullet of this embodiment of the invention only includes the nozzle 1, the flexible member 2 and the cup body 3 to form a complete airflow channel, which simplifies the structure, makes assembly easier, and reduces costs. In addition, the spiral air passage 4 is provided between the flexible member 2 and the cup body 3, which can make the airflow spiral. The spiral airflow can improve the carry-out efficiency of the atomized gas in the cup body 3, thereby improving the atomization utilization rate.
[0030] In some embodiments, the flexible member 2 may be made of a thermally insulating material to reduce the conduction of heat from the cup body 3 to the mouthpiece 1, thereby reducing the problem of the mouthpiece 1 absorbing too much heat from the cup body 3 and burning the mouth.
[0031] Please see Figure 2 and Figure 5 In some specific embodiments, the flexible component 2 can be made of environmentally friendly and heat-resistant silicone material. Along the axial direction of the flexible component 2, a support rib can be provided at the end of the flexible component 2 facing the nozzle component 1 to support the flexible component 2 and prevent the flexible component 2 from sinking. The nozzle component 1 can be made of food-grade plastic material, such as PC2456, thereby improving the safety of the atomizing bullet.
[0032] It should be noted that the axial direction is parallel to Figure 1 The direction of the Z-axis.
[0033] Further, please see Figure 3 In some specific embodiments, the flow area of the air inlet 11 is smaller than the flow area of the spiral air passage 4.
[0034] Specifically, the spiral air passage 4 is formed between the flexible member 2 and the cup body 3, and during the assembly of the flexible member 2 and the cup body 3, the spiral air passage 4 can be squeezed, and the suction nozzle member 1 and the flexible member 2 are molded by a mold, and there is a certain error in size, which can also affect the flow area of the spiral air passage 4. Therefore, by setting the flow area of the air inlet 11 to be smaller than the flow area of the spiral air passage 4, the air inlet 11 becomes the only suction resistance control point of the atomizing cartridge, which can make the suction resistance control more accurate and consistent, and can reduce the influence of the size error of the material on the suction resistance. In addition, since the air inlet 11 is opened on the outer side of the suction nozzle member 1, the suction resistance control is also more convenient. When fine adjustment of the suction resistance is needed, only the mold of the suction nozzle member 1 needs to be fine adjusted.
[0035] Further, please refer to Figure 1 and Figure 2 In some specific embodiments, the suction nozzle member 1 includes a base 12 and a mouth 13 connected to the end of the base 12 away from the cup body 3, the base 12 is fixedly connected to the open end of the cup body 3 through the flexible member 2, the air inlet 11 is arranged on the side wall of the end of the mouth 13 close to the base 12, and the air outlet 132 is formed at the end of the mouth 13 away from the base 12.
[0036] Specifically, the air inlet 11 and the air outlet 132 are both arranged in the mouth 13, wherein the air inlet 11 is close to the base 12, and the air outlet 132 is away from the base 12, and the base 12 is connected to the open end of the cup body 3 through the flexible member 2, so that the airflow path on the atomizing cartridge is approximately "U" shaped, thereby timely supplementing the airflow and timely removing the atomized gas.
[0037] Wherein, the mouth 13 has a certain inclination angle relative to the axial direction of the cup body 3, wherein the inclination angle can be between 0°-60°, specifically, the inclination angle can be 5°-45°, for example, the inclination angle can be 5°, 10°, 15°, 20°, 25°, 30°, 40° or 45°, etc.
[0038] Specifically, the cup body 3 can be used to contain atomizing medium. The cup body 3 generates heat away from the open end, i.e. the bottom of the cup body 3 can be a heating surface, thereby heating the atomizing medium to form atomized gas, so that an atomizing passage 31 is defined in the cup body 3. The airflow can pass through the air inlet 11, the spiral air passage 4 and then enter the atomizing passage 31, and then pass through the air outlet 132 opened on the mouth 13 to be discharged, so that the user can suck the atomized gas through the mouth 13. By setting the mouth 13 to have a certain inclination angle relative to the axial direction of the cup body 3, the user can use the cup body 3 vertically when sucking through the mouth 13, so that the atomizing medium in the cup body 3 is horizontal to the heating surface of the cup body 3, at this time the atomizing effective area of the heating surface is maximum, thereby the atomizing efficiency is optimal and the dry burning risk is minimum.
[0039] Further, referring to Figure 1 and Figure 3 In some specific embodiments, the aerosolizing cartridge further forms an air outlet channel that is in communication with the aerosolizing channel 31, the air outlet channel is formed in the flexible member 2 and the mouthpiece 1, and the air outlet channel forms an air outlet 132 at an end of the mouthpiece 1 that is distal to the flexible member 2, and the flow area of the air outlet channel is greater than the flow area of the spiral air passage 4.
[0040] Specifically, the cup 3 can be an integrated glass pot or a combination of a glass tube and a glass sheet with a sintered bottom, and the cup 3 contains the aerosolizing medium, which can be transparent quartz glass or high borosilicate glass, which not only has good temperature resistance but also has a transparent side that can facilitate observation of the remaining amount of aerosolizing medium in the cup 3 during use. The bottom of the cup 3 can be coated with a layer of metal film, which can be a heating surface for heating the aerosolizing medium in the cup 3 to form aerosolizing gas, thereby defining an aerosolizing channel 31 in the cup 3. In addition, the aerosolizing cartridge further includes an air outlet channel that is in communication with the aerosolizing channel 31, part of the air outlet channel is formed in the flexible member 2 and the other part of the air outlet channel is formed in the mouthpiece 1, and the air outlet channel (i.e. the other part of the air outlet channel) in the mouthpiece 1 forms an air outlet 132 at an end distal to the flexible member. Therefore, the airflow from the air inlet 11 passes through the spiral air passage 4 to the bottom of the cup 3, i.e. the airflow can flow to the aerosolizing channel 31, and the aerosolizing gas in the aerosolizing channel 31 is blown up and blown to the air outlet channel, and finally discharged to the air outlet 132 for the user to inhale from the mouthpiece 13. In addition, the flow area of the air outlet channel is greater than the flow area of the spiral air passage 4, i.e. the flow area of the air outlet channel is relatively large, thereby helping to carry out the aerosolizing gas and improving the utilization rate of the aerosolizing. In addition, the flow area of the air outlet channel is greater than the flow area of the spiral air passage 4, and the flow area of the spiral air passage 4 is greater than the flow area of the air inlet 11, thereby ensuring that the air inlet 11 is the only resistance control point, which can make the resistance control more accurate and consistent.
[0041] Further, for example, the flow area of the air outlet channel can be about 7.1 square millimeters, the flow area of the spiral air passage 4 can be about 2.45 square millimeters, and the flow area of the air inlet 11 can be about 0.65 square millimeters. In addition, the flow area of the opening of the end of the spiral air passage 4 close to the air inlet 11 can be 2.3 square millimeters, so that the flow area of the opening of the end of the spiral air passage 4 close to the air inlet 11 is less than the flow area of the spiral air passage 4 and greater than the flow area of the air inlet 11.
[0042] Further, referring to Figure 1 and Figure 3In some specific embodiments, the flexible piece 2 is provided with a first sealing part 21, the mouth part 13 is internally defined with an exhaust section 131 forming an air outlet 132; the base part 12 is internally provided with a ventilation pipe 121 connected to the mouth part 13, the ventilation pipe 121 is internally defined with a ventilation section 1211 communicating with one end of the exhaust section 131 away from the air outlet 132, the ventilation pipe 121 and the inner wall of the mouth part 13 near the base part 12 are defined with an air inlet space 5 communicating with the air inlet 11, the ventilation section 1211 and the exhaust section 131 form an air outlet channel; the first sealing part 21 is located between the outer wall of the ventilation pipe 121 and the inner wall of the cup body 3, the outer wall of the first sealing part 21 is provided with a spiral groove 24 communicating with the air inlet space 5, and the spiral groove 24 and the inner wall of the cup body 3 form a spiral air passage 4.
[0043] Specifically, the air outlet channel includes the ventilation section 1211 and the exhaust section 131, wherein the exhaust section 131 is formed in the mouth part 13, the air outlet end is formed in the ventilation pipe 121, and the air inlet space 5 is formed between the outer wall of the ventilation pipe 121 and the inner wall of the mouth part 13, at the same time, the spiral air passage 4 is formed between the spiral groove 24 and the inner wall of the cup body 3, and the spiral groove is opened on the outer wall of the first sealing part 21, and the first sealing part 21 is located between the outer wall of the ventilation pipe 121 and the inner wall of the cup body 3, so that sealing can be realized, and the air outlet channel, the air inlet space 5 and the spiral air passage 4 are arranged separately, so that the air inlet process and the air outlet process can be avoided from affecting each other.
[0044] In addition, in some specific embodiments, the size of the first sealing part 21 extending to the bottom of the cup body 3 is greater than the size of the ventilation pipe 121 extending to the bottom of the cup body 3, so that the ventilation pipe 121 is away from the atomized medium in the cup body 3, thereby further avoiding the atomized medium in the cup body 3 from splashing and scalding the ventilation pipe 121 of the mouth piece 1 or the bottom of the cup body 3 when atomized.
[0045] Further, please refer to Figures 1 to 5 In some specific embodiments, the transverse cross-sectional shape of the spiral groove 24 can be semicircular, and the transverse cross-sectional shape of the air inlet 11 and the air outlet channel can be circular, thereby facilitating the flow of gas in the air passage and reducing the use noise.

In addition, the cup 3 is used to accommodate the atomization medium, and thus the interference amount between the flexible member 2 and the cup 3 can be designed so that the atomization cartridge can be used once or can be refilled for repeated use.
