The aerosol in the atomization channel flows directly to the air outlet channel. However, since the aerosol forms larger aerosol particles in the atomization channel and the air outlet channel due to heat release or collision, the larger aerosol particles are also prone to form condensation, which affects the user's taste.

[0029] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0030] See also Figure 1-5 The embodiment of the utility model provides an electronic atomization device, comprising a liquid storage chamber 101 and an air outlet channel 102 arranged at intervals in the transverse direction, and an atomization channel 103 located at the bottom of the liquid storage chamber 101 and connected to the air outlet channel 102. The electronic atomization device also includes an atomization core 2, the atomization core 2 has a liquid suction surface connected to the liquid of the liquid storage chamber 101, and an atomization surface 21 facing the atomization channel 103; a flow blocking portion 11 is provided between the atomization channel 103 and the air outlet channel 102, the flow blocking portion 11 defines a connecting port connecting the atomization channel 103 and the air outlet channel 102, and the connecting port is in a shrinking shape in the direction from the atomization channel 103 to the air outlet channel 102.

[0031] In the embodiment of the utility model, the liquid in the liquid storage chamber 101 flows to the liquid absorption surface of the atomizer core 2, and the atomized liquid is heated and atomized on the atomization surface 21 of the atomizer core 2 to form an aerosol, and the aerosol flows from the atomization channel 103 to the gas outlet channel 102. Among them, the gas outlet channel 102 extends in the longitudinal direction, and the atomization channel 103 extends in the transverse direction. By setting the flow blocking part 11 between the atomization channel 103 and the gas outlet channel 102, the aerosol in the atomization channel 103 needs to pass through the connecting port of the flow blocking part 11 and then flow to the gas outlet channel 102. Since the connecting opening is in a narrowing shape in the direction from the atomization channel 103 to the air outlet channel 102, on the one hand, the flow rate of the aerosol flowing from the atomization channel 103 to the air outlet channel 102 can be increased, and the aerosol can be discharged in time; on the other hand, the flow blocking portion 11 can block the large-particle aerosol formed in the atomization channel 103 from flowing toward the air outlet channel 102, thereby reducing the presence of larger-particle aerosol or condensate formed by large-particle aerosol in the air outlet channel 102, so as to improve the taste of the aerosol when inhaled.

[0032] Furthermore, the atomizing surface 21 is provided with a heating element 3. The atomizing surface 21 is used as a reference plane, and the reference plane has a direction parallel to the air flow path in the atomizing channel 103 as a first direction and a direction orthogonal to the first direction as a second direction. In the second direction, the ratio of the dimension W2 of the connecting port on the side close to the air outlet channel 102 to the dimension W1 of the heating element 3 is 0.8-1.2.

[0033] In some specific embodiments, the atomizing surface 21 and the heating element 3 extend along the first direction, and the second direction is the width direction of the atomizing surface 21 and the heating element 3. The connecting port is in a constricted shape from the atomizing channel 103 to the air outlet channel 102, and the connecting port is between the atomizing channel 103 and the air outlet channel 102. Therefore, the size of the connecting port on the side close to the air outlet channel 102 is the minimum size of the connecting port in the second direction, and the size of the connecting port on the side close to the atomizing channel 103 is the maximum size of the connecting port in the second direction. The ratio of the width W1 of the heating element 3 to the minimum size W2 of the connecting port can be 0.8, 0.82, 0.85, 0.88, 0.9, 0.92, 0.95, 0.98, 1, 1.02, 1.05, 1.08, 1.1, 1.12, 1.15, 1.18, 1.2, etc. By setting the ratio of the width W1 of the heating element 3 and the minimum size W2 of the connecting port to 0.8-1.2, the aerosol generated by heating the heating element 3 can flow to the connecting port along the airflow path without being dispersed, and the large-particle aerosol can be blocked by the blocking part when passing through the connecting port and return to the heating element 3 to be reheated and atomized, while the small-particle aerosol can smoothly pass through the connecting port and finally flow smoothly to the air outlet channel 102.

[0034] It can be understood that when the atomizing surface 21 of the atomizing core 2 extends along the direction of the airflow path in the atomizing channel 103, that is, when the length direction of the atomizing surface 21 is parallel to the direction of the airflow path in the atomizing channel 103, the first direction is the length direction of the atomizing surface 21, and correspondingly, the second direction is the width direction of the atomizing surface 21. In addition, the atomizing channel 103 extends in the transverse direction, and the direction of the airflow path in the atomizing channel 103 is parallel to the transverse direction, so that the length direction of the atomizing surface 21 is parallel to the transverse direction. Among them, the first direction X and the second direction Y are two different transverse directions, see Figure 1 The direction parallel to the X direction of the coordinate system in the figure is the length direction of the atomized surface 21, the direction parallel to the Y direction of the coordinate system in the figure is the width direction of the atomized surface 21, and the direction parallel to the Z direction of the coordinate system in the figure is the longitudinal direction.

[0035] It should be noted that the first direction X may also be the width direction of the atomized surface 21 . In this case, the second direction Y is the length direction of the atomized surface 21 .

[0036] Further, in the second direction, the ratio of the dimension W3 of the end of the air outlet channel 102 close to the communication port to the dimension W1 of the heating element 3 is 1-2.6.

[0037] Specifically, the ratio of the size W3 of one end of the air outlet channel 102 close to the connecting port to the size W1 of the heating element 3 can be 1, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, 2, 2.1, 2.2, 2.3, 2.4, 2.5, or 2.6. When the aerosol generated by the heating element 3 passes through the connecting port, the large-particle aerosol has been blocked and returned. By setting the ratio of the size W3 of the end of the air outlet channel 102 close to the connecting port to the size W1 of the heating element 3 to 1-2.6, the end of the air outlet channel 102 close to the connecting port has sufficient flow space, which can effectively prevent small-particle aerosol from accumulating at the end of the air outlet channel 102 close to the connecting port, but will not be too dispersed; at the same time, more small-particle aerosol can flow out at the connecting port, and the small-particle aerosol can flow to the air outlet channel 102 more quickly and continuously, and flow in the spacious flow space of the air outlet channel 102, and finally bring out more uniform small-particle aerosol.

[0038] Further, in the second direction, W3 is greater than W2, and W2 is less than or equal to W1.

[0039] Specifically, the dimension W3 of the end of the air outlet channel 102 close to the connecting port is the largest, and the minimum dimension of the connecting port is less than or equal to the dimension of the heating element 3. Therefore, among the aerosols generated by the heating element 3, more large-particle aerosols can be blocked by the blocking portion; at the same time, the flow of small-particle aerosols will not be affected, and the small-particle aerosols can smoothly flow from the atomization channel 103 to the connecting port and finally to the air outlet channel 102; in addition, a large amount of small-particle aerosols will not accumulate at the end of the air outlet channel 102 close to the connecting port, so as to prevent condensation from being sucked into the air during inhalation and affecting the taste.

[0040] Furthermore, one end of the air outlet channel 102 away from the connecting port is the air outlet, and the radial dimension of the air outlet channel 102 gradually decreases in the direction from the connecting port to the air outlet.

[0041] In some specific embodiments, the air outlet channel 102 extends longitudinally, and the air outlet channel 102 may be trumpet-shaped, wherein the end with a larger diameter faces the connecting port, and the end with a smaller diameter is the air outlet. Therefore, when the small particle aerosol flows from the connecting port to the air outlet channel 102, it may have a larger circulation space, so that a large amount of small particle aerosol will flow from the connecting port to the air outlet channel 102. When the small particle aerosol flows in the air outlet channel 102, as the radial dimension of the air outlet channel 102 gradually decreases, the flow rate of the small particle aerosol in the air outlet channel 102 may gradually increase, so that under the same suction time and strength, more aerosol can be brought out from the air outlet, wherein the condensate formed in the air outlet channel 102 is difficult to climb to the air outlet end, further reducing the user from inhaling the condensate.

[0042] Furthermore, taking the atomizing surface 21 as a reference plane, the reference plane has a direction parallel to the airflow path in the atomizing channel 103 as a first direction and a direction orthogonal to the first direction as a second direction, and the blocking portion 11 includes two split portions 111 arranged at intervals along the second direction to form a connecting port.

[0043] Specifically, the two split parts 111 are arranged at intervals along the second direction, so as to form a communication port along the airflow path. The aerosol formed in the atomization channel 103 passes through the two split parts 111, and most of the large-particle aerosol will be blocked by the two split parts 111, while the small-particle aerosol will flow along the two split parts 111 to the air outlet channel 102, so that the aerosol particles flowing to the air outlet channel 102 have small and uniform particle sizes, so as to improve the inhalation taste of the aerosol.

[0044] Furthermore, at least one side of the split portion 111 facing the atomization channel 103 has a guide surface 1111 inclined from the atomization channel 103 to the gas outlet channel 102 .

[0045] In some specific embodiments, the two split parts 111 are symmetrically arranged, so that the two guide surfaces 1111 are arranged opposite to each other, both facing the atomization channel 103. And from the atomization channel 103 to the direction of the air outlet channel 102, the two guide surfaces 1111 gradually approach each other, so that the connecting port is in a constricted shape. The aerosol formed in the atomization channel 103 passes through the guide surfaces 1111 of the two split parts 111, and most of the large-particle aerosols will be blocked by the guide surfaces 1111 of the two split parts 111 and return to the atomization surface 21 of the atomization core 2, while the small-particle aerosol will flow along the guide surfaces 1111 of the two split parts 111 to the air outlet channel 102, so that the aerosol particles flowing to the air outlet channel 102 have small and uniform particle sizes, so as to improve the inhalation taste of the aerosol.

[0046] It can be understood that in some embodiments, the two split parts 111 can be arranged asymmetrically, and one of the split parts 111 can have a guide surface 1111 inclined from the atomization channel 103 to the gas outlet channel 102, while the other split part 111 is not provided with the guide surface 1111. The inclined guide surface 1111 can also block large-particle aerosols. At the same time, in the direction from the atomization channel 103 to the gas outlet channel 102, the inclined guide surface 1111 can gradually approach the other split part 111, so that the communication port is in a constricted shape, thereby gradually increasing the flow rate of the small-particle aerosol at the communication port.

[0047] Further, the guide surface 1111 includes a curved surface or a plane. In some embodiments, the guide surfaces 1111 of the two split parts 111 can both be curved surfaces. In some embodiments, the guide surfaces 1111 of the two split parts 111 can both be inclined planes. In some embodiments, the guide surface 1111 of one split part 111 is a curved surface, and the guide surface 1111 of the other split part 111 is an inclined plane.

[0048] Furthermore, the electronic atomization device also includes an oil cup bracket 1 and a first sealing member 4, a liquid storage chamber 101 and an air outlet channel 102 are formed in the oil cup bracket 1, the oil cup bracket 1 is formed with a through hole, the through hole includes an assembly through hole and a connecting through hole distributed longitudinally along the oil cup bracket 1, the atomization core 2 is assembled in the assembly through hole, and the atomization channel 103 is formed in the connecting through hole; the first sealing member 4 is clamped between the outer peripheral side of the atomization core 2 and the inner side wall of the assembly through hole; the flow blocking portion 11 is formed on the inner side wall of the connecting through hole.

[0049] In some specific embodiments, the flow blocking portion 11 includes two split portions 111, one of which protrudes from the inner side wall of the connecting through hole along the first direction, and the other split portion 111 protrudes from the other opposite inner side wall of the connecting through hole. And from the inner side wall of the connecting through hole, the guide surface 1111 of the split portion 111 is inclined toward the direction of the air outlet channel 102, so that the two guide surfaces 1111 are close to each other, so that the connecting port is in a constricted shape. The first sealing member 4 is clamped between the inner side wall of the assembly through hole and the outer peripheral side of the atomizer core 2, so as to seal the gap between the atomizer core 2 and the oil cup bracket 1, and at the same time, it can also isolate the heat of the atomizer core 2, prevent the loss of heat of the atomizer core 2, and improve energy utilization.

[0050] Furthermore, the electronic atomization device also includes a nozzle 5 and a base 7. The nozzle 5 is assembled with the oil cup bracket 1 and is located at one end of the air outlet channel 102 away from the connecting port. The nozzle 5 has an opening connecting the outside and the air outlet channel 102; the base 7 is assembled at one end of the oil cup bracket 1 away from the nozzle 5, and the base 7 is formed with an air inlet channel 701 connecting the atomization channel 103 and the outside.

[0051] Specifically, the air outlet channel 102 has an air outlet, the suction nozzle 5 is located at one end of the air outlet of the air outlet channel 102, and the opening of the suction nozzle 5 is connected to the air outlet of the air outlet channel 102. The external airflow flows from the air inlet channel 701 of the base 7 to the atomization channel 103, and the airflow and aerosol flow from the atomization channel 103 through the circulation port to the air outlet channel 102. The airflow and aerosol flow in the air outlet channel 102 to flow to the air outlet, and then flow to the opening of the suction nozzle 5 through the air outlet, and finally flow to the outside for the user to inhale or use. In addition, the electronic atomization device also includes a second sealing member 6 for sealing the suction nozzle 5 and the oil cup bracket 1, and the second sealing member 6 also has an opening connecting the outside and the air outlet channel 102. The opening of the suction nozzle 5 and the opening of the second sealing member 6 are aligned and connected.

[0052] Furthermore, the electronic atomization device also includes a battery rod assembly 8, which includes a battery rod housing 81, a battery 82, an electrode 86, a circuit board 83, a switch button 85 and a button silica gel 84. The oil cup bracket 1 and the battery 82 can be detachably connected to the battery rod housing 81, and the oil cup bracket 1 and the battery 82 are arranged in a lateral interval. The circuit board 83 is assembled in the battery rod housing 81 and is located at the bottom of the base 7 and the battery 82. The battery 82 is used to provide power to the circuit board 83. The electrode 86 electrically connects the circuit board 83 and the heating element 3, so that the heating element 3 can generate heat to heat the atomized liquid in the liquid storage chamber 101. The button silica gel 84 is arranged on the circuit board 83, and the switch button 85 abuts against the button silica gel 84 and is exposed in the battery rod housing 81.
