Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of electronic atomization, in particular to an atomization support, an atomizer and an electronic atomization device. BACKGROUND
[0002] As a substitute for traditional cigarettes, an electronic atomization device usually comprises a power supply device and an atomizer. The atomizer usually comprises a hollow shell and an atomization core arranged inside the shell. The power supply device is used to supply power to the atomization core. The interior of the shell has a liquid storage cavity, an atomization channel and an atomization cavity leading to the atomization channel. The atomization core usually comprises an oil guide body and a heating body. The liquid storage cavity is used to supply atomization liquid to the atomization core. The oil guide body is used to guide the atomization liquid supplied by the liquid storage cavity to the heating body. The heating body is used to heat the atomization liquid supplied by the liquid storage cavity to form a smokeable aerosol in the atomization cavity leading to the atomization channel. Compared with traditional cigarettes, the electronic atomization device has the advantages of no tar, no ash and no open flame, and can effectively avoid the generation of various harmful substances in the ignition state of traditional cigarettes.
[0003] During use of the electronic atomization device, a negative pressure is formed in the atomization cavity and the atomization channel due to the user's puffing. The negative pressure formed in the atomization cavity and the atomization channel can act on the liquid storage cavity through the oil guide body, so that the atomization liquid in the liquid storage cavity is supplied to the atomization core under the action of the negative pressure and is heated and atomized. As the atomization liquid in the liquid storage cavity decreases, the negative pressure gradually accumulates in the liquid storage cavity. When the negative pressure in the liquid storage cavity accumulates to a certain extent, the user can hardly drive the atomization liquid in the liquid storage cavity to be supplied to the atomization core through the puffing action, thereby causing the atomization core to be difficult to generate sufficient aerosol due to insufficient liquid supply, and even causing the heating body to dry out, thereby affecting the user's puffing experience. Therefore, a back gas structure is designed in the atomizer in the related art to make the liquid storage cavity communicate with the external atmosphere. When the negative pressure is generated in the liquid storage cavity due to the decrease of the atomization liquid, the negative pressure formed in the liquid storage cavity can be eliminated through the back gas structure. However, the atomization liquid in the liquid storage cavity can leak through the back gas structure due to capillary force, and the conventional back gas structure cannot better solve this problem.

[0034] With reference to Figures 1 to 7 According to the atomizing support of the embodiments of the present application, the atomizing support comprises a support body 100 and a gas return structure.
[0035] Specifically, the gas return structure is arranged at the side of the support body 100, and the gas return structure comprises a main gas return channel 110 extending in the transverse direction, the main gas return channel 110 comprises an air inlet end 111 and an air outlet end 112, the air inlet end 111 of the main gas return channel 110 is used to communicate with the external atmosphere, the air outlet end 112 of the main gas return channel 110 is used to communicate with the liquid storage cavity 500, the main gas return channel 110 has a flow resistance section 113 extending between the air inlet end 111 and the air outlet end 112, wherein the highest point of the flow resistance section 113 in the longitudinal direction is higher than the air outlet end 112 of the main gas return channel 110, and / or the height of the air inlet end 111 of the main gas return channel 110 in the longitudinal direction is higher than the air outlet end 112 of the main gas return channel 110.
[0036] It should be noted that the transverse direction is the X direction in the drawings, and the longitudinal direction is the Y direction in the drawings.
[0037] The atomizing support of the embodiments of the present application is applied to an atomizer of an electronic atomizing device. During use of the electronic atomizing device, as the atomizing liquid in the liquid storage cavity 500 decreases, a negative pressure is formed in the liquid storage cavity 500. The negative pressure formed in the liquid storage cavity 500 can act on the external atmosphere through the main gas return channel 110, so that the external air enters the liquid storage cavity 500 through the main gas return channel 110, thereby eliminating the negative pressure formed in the liquid storage cavity 500. The main gas return channel 110 has a flow resistance section 113 extending between the air inlet end 111 and the air outlet end 112, wherein the highest point of the flow resistance section 113 in the longitudinal direction is higher than the air outlet end 112 of the main gas return channel 110, and / or the height of the air inlet end 111 of the main gas return channel 110 in the longitudinal direction is higher than the air outlet end 112 of the main gas return channel 110. When the atomizing liquid in the liquid storage cavity 500 enters the main gas return channel 110, the atomizing liquid entering the main gas return channel 110 needs to overcome its own gravity to leak through the main gas return channel 110, thereby weakening the influence of capillary force, i.e. increasing the difficulty of the atomizing liquid leaking through the main gas return channel 110, thereby facilitating reduction of the risk of the atomizing liquid leaking through the gas return structure.
[0038] It should be noted that when the highest point of the choke section 113 in the longitudinal direction is higher than the outlet end 112 of the main return air passage 110, the height of the inlet end 111 of the main return air passage 110 in the longitudinal direction can be higher than, lower than, or level with the outlet end 112 of the main return air passage 110, which is not limited herein.
[0039] With reference to Figure 1 and Figure 2 In some embodiments, the choke section 113 is a bending section formed by the longitudinal protrusion of the main return air passage 110, which is simple in structure and easy to implement.
[0040] It should be noted that in some other embodiments, the choke section 113 can also be wavy or other shapes, which are not limited herein.
[0041] With reference to Figure 1 and Figure 2 In some embodiments, the return air structure further comprises at least one choke passage 120 connected in series to the main return air passage 110, and the maximum diameter of the choke passage 120 is greater than the maximum diameter of the main return air passage 110. Since the maximum diameter of the choke passage 120 is greater than the maximum diameter of the main return air passage 110, when the atomized liquid entering the main return air passage 110 enters the choke passage 120, the flow velocity of the atomized liquid can be reduced due to the increase in fluid cross section, and at the same time, the influence of capillary force can be further weakened due to the increase in space for the flow of atomized liquid, thereby further reducing the risk of leakage of atomized liquid through the return air structure.
[0042] It should be noted that in some embodiments, the maximum diameter of the choke passage 120 is a, and the maximum diameter of the main return air passage 110 is b, wherein a≥3b, thereby facilitating the guarantee of the choke effect of the choke passage 120.
[0043] With reference to Figure 1 and Figure 2 In some embodiments, the choke passage 120 is located between the outlet end 112 of the main return air passage 110 and the choke section 113.
[0044] With reference to Figure 1 and Figure 2 In some embodiments, the main return air passage 110 has a vertical section 114 extending in the longitudinal direction and connected between the outlet end 112 and the choke section 113 thereof, and the choke passage 120 is connected in series to the vertical section 114, so that the atomized liquid entering the choke passage 120 needs to fill the choke passage 120 to pass through the choke passage 120 and continue to flow forward, thereby increasing the difficulty of the atomized liquid passing through the choke passage 120, and further reducing the risk of leakage of the atomized liquid through the return air structure.
[0045] Referring to Figure 1 and Figure 2 In some embodiments, the gas return structure further comprises at least one shunt channel 130 connected in parallel to the main gas return channel 110, and the start end and the end of the shunt channel 130 are connected to the main gas return channel 110. On the one hand, the atomized liquid flowing into the main gas return channel 110 will be shunted when flowing through the shunt channel 130, thereby reducing the flow speed of the atomized liquid and extending the flow path of the atomized liquid. On the other hand, the shunt has a double channel, that is, the space for the atomized liquid to flow is increased, thereby further weakening the influence of capillary force, and the above two aspects are conducive to further reducing the risk of leakage of the atomized liquid through the gas return structure.
[0046] It should be noted that in some embodiments, the length of the part of the main gas return channel 110 between the start end and the end of the shunt channel 130 is less than the length of the shunt channel 130, thereby facilitating further extension of the flow path of the atomized liquid, and further reducing the risk of leakage of the atomized liquid through the gas return structure.
[0047] It should be noted that in some embodiments, the length of the part of the main gas return channel 110 between the start end and the end of the shunt channel 130 is m, and the length of the shunt channel 130 is n, wherein 1.5m≤n≤2m, thereby facilitating to ensure the flow resistance effect of the shunt channel 130.
[0048] Referring to Figure 1 and Figure 2 In some embodiments, the shunt channel 130 cooperates with the main gas return channel 110 to form a Tesla valve. When the external air flows from the gas inlet end 111 of the main gas return channel 110 to the gas outlet end 112 of the main gas return channel 110, it will not be hindered by the Tesla valve, making it easy for the external air to enter the liquid storage cavity. When the atomized liquid in the liquid storage cavity flows from the gas outlet end 112 of the main gas return channel 110 to the gas inlet end 111 of the main gas return channel 110, the atomized liquid will be hindered by the Tesla valve, that is, the atomized liquid entering the shunt channel 130 will collide with the atomized liquid in the main gas return channel 110 when it re-enters the main gas return channel 110, thereby hindering the atomized liquid in the main gas return channel 110, and further reducing the risk of leakage of the atomized liquid through the gas return structure.
[0049] Referring to Figures 4 to 7In some embodiments, the top of the support body 100 is provided with a lower oil groove 140 for communicating with the liquid storage cavity 500, and the gas outlet end 112 of the main air return channel 110 is connected to the lower oil groove 140. By providing the lower oil groove 140, the height of the gas outlet end 112 of the main air return channel 110 in the longitudinal direction can be lower than the top of the support body 100, so that the highest point of the corresponding flow resistance section 113 in the longitudinal direction can be higher than the gas outlet end 112 of the main air return channel 110.
[0050] With reference to Figure 6 and Figure 7 According to the atomizer of the embodiments of the present application, the atomizer includes the atomizing support described above, and further includes an oil cup 200, an atomizing core 300, and an air passage piece 400. The atomizing support is at least partially located inside the oil cup 200, and the support body 100 and the inner wall of the oil cup 200 form a liquid storage cavity 500 for storing atomizing liquid. The atomizing core 300 and the air passage piece 400 are both assembled on the support body 100, and the atomizing core 300 and the air passage piece 400 form an atomizing cavity 600 that is open to the atomizing channel 210.
[0051] It can be understood that, since the atomizer of the embodiments of the present application includes the atomizing support described above, the atomizer of the embodiments of the present application has all the technical effects of the atomizing support described above.
[0052] With reference to Figure 6 and Figure 7 In some embodiments, the atomizer further includes a sealing piece 700 for sealing the fitting gap between the support body 100 and the inner wall of the oil cup 200.
