Description

Technical Field

[0001] The present application relates to the technical field of atomization, and particularly to an atomizer and an electronic atomization device. Background Art

[0002] An electronic atomization device, also known as an electronic cigarette, virtual cigarette, vapor cigarette, aerosol generating device, etc., is mainly used to simulate the smoking feeling without affecting health for smoking cessation or replacing cigarettes. As one of the core components of an electronic atomization device, the atomization core is mostly made of ceramic materials. Compared with traditional cotton cores or fiberglass ropes, the ceramic atomization core has the advantages of strong lipophilicity, uniform heating, and high operating temperature.

[0003] During the use of an electronic atomization device, whether the e-liquid can continuously and stably flow to the surface of the heating element of the atomization core is one of the core factors to ensure the stability of the amount of smoke formed by heating and atomizing the e-liquid and the satisfaction of the consumer's smoking experience. The prerequisite for realizing this function is to reasonably design the relationship between the sealing effect of the e-liquid in the oil storage cavity and the air inlet holes required for gas-liquid balance. Currently, the following problems mainly exist in the gas-liquid balance of electronic atomization devices in the industry: In order to avoid e-liquid leakage, some atomizers are designed with too tight assembly of the e-liquid seal, and the air inlet grooves around the seal are designed too small or not designed at all. As a result, during the consumer's inhalation process, the negative pressure generated inside the oil storage cavity cannot reach air pressure balance with the external environment in time through the external air flow. Once the air pressure balance cannot be achieved in time, the e-liquid cannot be quickly and smoothly driven to the surface of the atomization core, and the specific phenomenon is that the amount of e-liquid flowing to the atomization core varies and the amount of smoke is unstable. Summary of the Utility Model

[0004] Based on this, it is necessary to provide an atomizer and an electronic atomization device including the atomizer that can solve the problem of unsmooth e-liquid flow from the existing atomizer of the electronic atomization device to the atomization core.

The gas-liquid balance member is configured such that when external air enters the gas-liquid balance channel from the air inlet hole, it can be actuated relative to the atomization unit by the air pressure exerted by the external air, so that the gas-liquid balance channel communicates with the oil storage cavity.

[0009] In one embodiment, the gas-liquid balance channel extends along the outer wall of the atomization unit in a bent manner.

[0010] In one embodiment, the gas-liquid balance channel includes a first channel, a second channel, and a third channel that are connected in sequence.

[0011] In one embodiment, the atomization unit includes a base assembly and a support assembly detachably connected to the base assembly;

[0012] A first flange is provided on the outer wall of the support assembly, and a second flange is provided on one side of the base assembly close to the support assembly. The first flange and the second flange are spaced apart and jointly form the gas-liquid balance channel.

[0013] In one embodiment, an air outlet hole is provided at one end of the housing away from the atomization unit, and an air flow channel communicating with the air outlet hole is provided in the housing. The space between the side of the support assembly away from the base assembly and the inner wall of the housing forms the oil storage cavity, and the space between the side of the support assembly facing the base assembly and the inner wall of the base assembly jointly forms the installation position. One end of the atomization core is connected to the support assembly, and the other end is connected to the base assembly;

[0014] The support assembly is provided with a separated oil guiding cavity and a gas guiding cavity. The installation position communicates with the oil storage cavity through the oil guiding cavity, and the installation position communicates with the air flow channel through the gas guiding cavity.

[0015] In one embodiment, the support assembly includes a bracket, a first seal, and a second seal. The first seal and the second seal are arranged at opposite ends of the bracket and form the oil guiding cavity with the inner wall of the bracket. The gas guiding cavity penetrates through the opposite side walls of the bracket. The gas-liquid balance member is arranged on the bracket and connected to the first seal. One end of the atomization core away from the base assembly is inserted into the second seal.

[0016] In one embodiment, the base assembly includes a base and a third seal. The third seal is disposed on the bottom wall of the base. One end of the atomization core away from the support assembly is inserted into the third seal, and a second flange is formed at an edge of one end of the base close to the support assembly.

[0020] In the above atomizer and electronic atomization device, by providing a gas-liquid balance channel communicating with the air inlet hole on the outer wall of the atomization unit, and isolating the oil storage cavity and the gas-liquid balance channel by providing a gas-liquid balance member on one side of the atomization unit close to the oil storage cavity, when the user sucks using the electronic atomization device and the air pressure in the oil storage cavity is too low, external air can enter the gas-liquid balance channel from the air inlet hole, thereby applying air pressure to the gas-liquid balance member to cause the gas-liquid balance member to lift upward relative to the atomization unit, and further enabling the gas-liquid balance channel to communicate with the oil storage cavity, so that the air pressure in the oil storage cavity is the same as the air pressure in the external environment to achieve air pressure balance. In this way, it can drive the atomization medium to flow to the atomization core quickly and smoothly, avoiding unstable smoke volume caused by unsmooth flow of the atomization medium, and further affecting the sucking taste; after the air pressure reaches balance, the gas-liquid balance member can return to its original position to isolate the oil storage cavity and the gas-liquid balance channel again, thereby preventing leakage of the atomization medium.

[0035] An embodiment of this application provides an atomizer and an electronic atomization device, wherein the electronic atomization device includes an atomizer, and the atomizer is used to heat the atomization medium inside itself to form an aerosol for the user to inhale.

[0036] Taking an electronic atomization device as an e-cigarette as an example below, the structures of the electronic atomization device and the atomizer in the present application will be described. This embodiment is only used as an example for illustration and will not limit the technical scope of the present application. It can be understood that in other embodiments, the electronic atomization device of the present application is not limited to an e-cigarette and can also be any other electronic atomization device that can atomize an atomization medium into an aerosol, which is not limited herein.

[0037] An electronic atomization device provided by an embodiment of the present application includes Figure 1 and Figure 2 the atomizer 10 and the power supply unit (not shown in the figure) as shown. The atomizer 10 is electrically connected to the power supply unit. The power supply unit is used to supply power to the atomizer 10, and the atomizer 10 is used to heat and atomize the atomization medium inside itself.

[0038] Referring to Figure 1 and Figure 2 , Figure 1 shows a schematic external view of the atomizer 10 in an embodiment of the present application, Figure 2 shows an exploded schematic view of the atomizer 10 of the above embodiment. The atomizer 10 provided by the embodiment of the present application includes a housing 100, an atomization unit 200, and an atomization core 300. One end of the housing 100 is open, and the other end has a mouthpiece 101. The mouthpiece 101 is provided with an air outlet hole 102, and an air flow channel 501 communicating with the air outlet hole 102 is provided inside the housing 100; the atomization unit 200 is disposed at the open end of the housing 100 and is provided with an air inlet hole 201. The atomization unit 200 and the inner wall of the housing 100 define an oil storage cavity 103 for storing the atomization medium; the atomization core 300 is disposed inside the atomization unit 200. When the electronic atomization device is working, the atomization medium (such as e-liquid) in the oil storage cavity 103 can flow into the atomization core 300, and the atomization core 300 heats and atomizes the atomization medium.

[0039] However, as described in the background art, whether the e-liquid can continuously and stably flow to the atomization core 300 is one of the core factors to ensure whether the amount of smoke formed by heating and atomizing the e-liquid is stable and whether the consumer's smoking experience is satisfactory. However, in order to avoid e-liquid leakage, some atomizers are designed with too tight assembly of the e-liquid seal, too small or no design of the air inlet groove around the seal, resulting in the negative pressure generated inside the oil storage cavity 103 during the consumer's smoking process not being able to reach air pressure balance with the external environment in time through the external air flow. Once the air pressure balance cannot be reached in time, the e-liquid cannot be quickly and smoothly driven to the surface of the atomization core 300. The specific phenomenon is that the amount of e-liquid flowing to the atomization core 300 varies and the amount of smoke is unstable.

[0040] Therefore, as Figure 3As shown in the figure, to solve the above problems, the researchers of this application conducted in-depth research and came up with the idea of opening an installation position 202 communicating with the air inlet hole 201 in the atomization unit 200, setting the atomization core 300 in the installation position 202, and opening a gas-liquid balance channel 203 on the outer wall of the atomization unit 200. The gas-liquid balance channel 203 communicates with the air inlet hole 201 through the installation position 202. At the same time, a gas-liquid balance member 400 is movably arranged on the side of the atomization unit 200 where the oil storage cavity 103 is formed, and the gas-liquid balance member 400 isolates the gas-liquid balance channel 203 from the oil storage cavity 103 from each other.

[0041] In this way, when the air pressure in the oil storage cavity 103 is too low, external air can enter the gas-liquid balance channel 203 from the air inlet hole 201, so that air pressure can be applied to the gas-liquid balance member 400 to make the gas-liquid balance member 400 move relative to the atomization unit 200 (for example, push the gas-liquid balance member 400 upward relative to the atomization unit 200), so that the gas-liquid balance channel 203 can communicate with the oil storage cavity 103, and then make the air pressure in the oil storage cavity 103 the same as the air pressure in the external environment to achieve air pressure balance, preventing the atomization medium from flowing smoothly. After the air pressure is balanced, the gas-liquid balance member 400 returns to its original position, isolating the oil storage cavity 103 and the gas-liquid balance channel 203 again to prevent the atomization medium from leaking.

[0042] It can be understood that the number of gas-liquid balance members 400 can be more than two, and the number of gas-liquid balance channels 203 corresponds to the number of gas-liquid balance members 400. Each gas-liquid balance member 400 can isolate a corresponding gas-liquid balance channel 203 from the oil storage cavity 103 from each other. It can also be understood that in other embodiments, the gas-liquid balance member 400 can also be an elastic element made of silica gel material. When external air applies pressure to the gas-liquid balance member 400, the gas-liquid balance member 400 can produce recoverable elastic deformation, so that it can also move relative to the atomization unit 200 to make the air pressure in the oil storage cavity 103 balance with the external air pressure. After the air pressure is balanced, the gas-liquid balance member 400 returns to its original state under the action of the elastic force, and can also isolate the oil storage cavity 103 and the gas-liquid balance channel 203 again.

[0043] Refer to Figure 4, in terms of the shape of the gas-liquid balance channel 203, the gas-liquid balance channel 203 extends along the outer wall of the atomization unit 200 in a bent manner. Specifically, the gas-liquid balance channel 203 includes a first channel 203a, a second channel 203b, and a third channel 203c that are connected in sequence. One end of the first channel 203a communicates with the installation position 202, and the other end is connected to the second channel 203b. One end of the third channel 203c is connected to the second channel 203b, and one end of the third channel 203c is connected to the second channel 203b, and the other end is closed by the gas-liquid balance member 400. After the outside air enters the installation position 202 from the air inlet 201, the air will sequentially pass through the first channel 203a, the second channel 203b, and the third channel 203c, and finally push open the gas-liquid balance member 400 and enter the oil storage cavity 103, so as to achieve the balance of the air pressure between the oil storage cavity 103 and the external environment.

[0044] It should be noted that the shape of the gas-liquid balance channel 203 is not limited to the shape shown in the embodiment in the figure, and can also be any shape such as a straight shape or a curved shape, which is not limited herein.

[0045] Specifically, in terms of the specific structure of the atomization unit 200, in combination with Figure 2 and Figure 4 as shown, the atomization unit 200 includes a base assembly 210 and a support assembly 220 detachably connected to the base assembly 210. The outer wall of the support assembly 220 is provided with a first flange 220a, and one side of the base assembly 210 close to the support assembly 220 has a second flange 210a. The first flange 220a and the second flange 210a are arranged at intervals and jointly form the gas-liquid balance channel 203. In the embodiment shown in the figure, the gas-liquid balance channel 203 extends in a bent manner, so the first flange 220a and the second flange 210a also extend in a bent manner.

[0046] Furthermore, in one embodiment, in combination with Figure 2 , Figure 4 and Figure 5 as shown, the side of the support assembly 220 facing the base assembly 210 and the inner wall of the base assembly 210 jointly form the installation position 202. The side of the support assembly 220 away from the base assembly 210 and the inner wall of the housing 100 form the oil storage cavity 103. One end of the atomization core 300 is connected to the support assembly 220, and the other end is connected to the base assembly 210; the support assembly 220 is also provided with an oil guiding cavity 204 and a gas guiding cavity 205 that are separated from each other. The installation position 202 communicates with the oil storage cavity 103 through the oil guiding cavity 204, and the installation position 202 also communicates with the air flow channel 501 through the gas guiding cavity 205 and the gap between the support assembly 220 and the inner wall of the housing 100 in sequence.

[0047] Furthermore, there is an air guiding column 500 inside the housing 100. The air guiding column 500 extends into the housing 100 from the end of the housing 100 where the air outlet hole 102 is provided (i.e., from the end with the suction nozzle 101). The air flow channel 501 penetrates through the air guiding column 500, and the end of the air guiding column 500 away from the air outlet hole 102 is inserted into the support assembly 220.

[0048] Please refer to Figure 2 and Figure 6 In the specific structure of the support assembly 220, the support assembly 220 includes a bracket 221, a first seal 222, and a second seal 223. The bracket 221 is connected to the base assembly 210. The first seal 222 and the second seal 223 are provided at opposite ends of the bracket 221 in the vertical direction in the figure. The first flange 220a is formed on the outer wall of the bracket 221. The air-liquid balance member 400 is disposed on the bracket 221 and connected to the first seal 222. The first seal 222, the second seal 223, and the inner wall of the bracket 221 form an oil guiding cavity 204. The air guiding cavity 205 penetrates through the opposite side walls of the bracket 221. The air guiding column 500 is inserted into the first seal 222. The side of the second seal 223 away from the first seal 222 and the inner wall of the base assembly 210 form an installation position 202. The end of the atomization core 300 away from the base assembly 210 is inserted into the second seal 223. The functions of the first seal 222 and the second seal 223 are to seal the support assembly 220 so that the atomization medium can only enter the oil guiding cavity 204 along a predetermined path and then enter the atomization core 300. Preferably, the oil guiding cavity 204 is U-shaped. The first seal 222 is provided with oil inlet holes 2221 on both sides of the air guiding column 500 along its radial direction, and each oil inlet hole 2221 communicates with the oil guiding cavity 204.

[0049] In this way, through the above settings, as Figure 6 shown by the dashed line in Figure 5 the atomization medium in the oil storage cavity 103 can enter the oil guiding cavity 204 respectively from the two oil inlet holes 2221 formed on the first seal 222 under the action of gravity, and then flow downward under the action of gravity and converge into the atomization core 300. At the same time, as Figure 4As shown by the dashed line in the figure, when a negative pressure is generated in the oil storage cavity 103, resulting in poor flow of the atomization medium, a part of the outside air entering the installation position 202 can still enter the gas-liquid balance channel 203 to push open the gas-liquid balance member 400, so that the gas-liquid balance channel 203 is communicated with the oil storage cavity 103, enabling the air pressure in the oil storage cavity 103 to reach equilibrium with the air pressure of the outside environment. As a result, there can be sufficient atomization medium continuously flowing into the atomization core 300, avoiding dry burning caused by poor flow of the atomization medium and thus preventing the generation of burnt smell, and therefore ensuring the user's inhalation taste.

[0050] Please continue to refer to Figure 2 and Figure 6 In the structure of the base assembly 210, the base assembly 210 includes a base 211, a third seal 212, and contact electrodes 213. The base 211 is connected to the bracket 221 of the support assembly 220, and the third seal 212 is attached to the inner wall of the base 211. A second flange 210a is formed at the edge of one end of the base 211 close to the support assembly 220. One side of the third seal 212, one side of the second seal 223, and the inner side wall of the base 211 together form the installation position 202. The end of the atomization core 300 away from the second seal 223 is inserted into the third seal 212. The function of setting the third seal 212 is to prevent the condensate generated after the aerosol in the installation position 202 cools from leaking out, thereby avoiding safety accidents such as short circuits caused by the condensate leaking into the power supply unit; there are two contact electrodes 213, namely the positive electrode and the negative electrode. Both contact electrodes 213 pass through the bottom wall of the base 211 and are inserted into the third seal 212 for connection to the power supply unit. The atomization core 300 is connected to the contact electrodes 213, enabling the atomization core 300 to be electrically connected to the power supply unit, so that heat can be generated under the action of the electric energy provided by the power supply unit to heat and atomize the atomization medium.

[0051] Preferably, an oil absorption member 214 is further embedded on the bottom wall of the base 211 on the side close to the third seal 212. The oil absorption member 214 is used to adsorb the atomization medium oozing from the bottom of the atomization core 300 or the condensate that may leak from the third seal 212, so as to further prevent the atomization medium or condensate from leaking into the power supply unit. In the embodiment shown in the figure, an installation groove 211a is formed on the bottom wall of the base 211, and the oil absorption member 214 is arranged in the installation groove 211a. One side of it is attached to the bottom wall of the installation groove 211a, and the other side is attached to the third seal 212, so that the condensate can be fully absorbed by the oil absorption member 214.

[0052] Further optionally, a magnetic attraction member 215 is also embedded on the bottom wall of the base 211. The magnetic attraction member 215 is used to adsorb the power supply unit, so that the atomizer 10 and the power supply unit can be more tightly connected to each other.

[0053] It should be noted that the gas-liquid balance channel 203 is not limited to being jointly formed by the first flange 220a of the support assembly 220 and the second flange 210a of the base assembly 210. The gas-liquid balance channel 203 can also be directly formed on the outer wall of the support assembly 220, or the support assembly 220 and the base assembly 210 are integrally connected, with a part of the gas-liquid balance channel 203 formed on the outer wall of the support assembly 220 and another part formed on the outer wall of the base assembly 210. No limitation is made herein.

[0054] In summary, for the atomizer 10 provided in the present application, a gas-liquid balance channel 203 and a gas-liquid balance member 400 are provided in the atomization unit 200. When the user sucks, the air pressure in the oil storage cavity 103 can be balanced with the outside air, so that the atomization medium can be driven to flow quickly and smoothly to the atomization core 300, avoiding unstable smoke volume caused by poor flow of the atomization medium and thus affecting the sucking taste. After the air pressure reaches balance, the gas-liquid balance member 400 can isolate the oil storage cavity 103 and the gas-liquid balance channel 203 again, thereby preventing leakage of the atomization medium and improving the user experience.

[0055] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0056] The above-described embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
