Description

Technical Field

[0001] This application relates to the field of electronic atomization technology, and in particular to an electronic atomization device. Background Technology

[0002] Electronic atomizing devices, also known as electronic cigarettes, are devices that use resistance heating to atomize liquid e-liquid into vapor at high temperatures. This vapor is then delivered to the consumer's mouth through an airway, replacing traditional tobacco and allowing the consumer to experience the pleasure of inhalation. Typically, electronic atomizing devices consist of an atomizer (commonly known in the industry as a cartridge) and a battery. The atomizer has an atomizing coil, and the battery powers the atomizing coil, which heats and atomizes the e-liquid to create an aerosol for the user to inhale.

[0003] Currently, in traditional electronic atomizing devices, the atomizer is a single unit after assembly and filling with e-liquid. Although there are seals to seal the atomizing medium, leakage during transportation and daily storage cannot be completely prevented. Moreover, because existing atomizers are all single units, the entire atomizer needs to be replaced after the e-liquid is exhausted, resulting in the inability to reuse the coil and other atomizing components, thus causing a certain amount of resource waste. Utility Model Content

[0004] Based on this, and in view of the shortcomings of the prior art, the purpose of this application is to provide an electronic atomizing device to solve the problems of easy oil leakage during transportation and the waste of resources caused by the non-reusability of components such as atomizing cores in existing electronic atomizing devices.

[0005] According to one aspect of this application, an electronic atomizing device is provided, comprising:

[0006] An oil storage unit is provided, wherein a first oil storage chamber and an air passage are provided inside the oil storage unit and are isolated from each other, and an air outlet connected to the air passage is provided at one end of the oil storage unit.

[0007] Atomizing unit is detachably connected to the oil storage unit. The atomizing unit has a second oil storage chamber that communicates with the first oil storage chamber. The second oil storage chamber has an atomizing core, and the atomizing core has an atomizing chamber. The atomizing unit has a first air inlet that communicates with the external environment. The first air inlet communicates with the air outlet through the atomizing chamber.

[0008] A power supply unit is detachably connected to the atomizing unit and electrically connected to the atomizing core.

[0009] In one embodiment, the atomizing unit has a second oil storage chamber that communicates with the first oil storage chamber, and the atomizing core is disposed in the second oil storage chamber.

[0010] In one embodiment, the oil storage unit includes a first housing and a first sealing assembly. The first housing is provided with a vent pipe, the air passage extends through the opposite ends of the vent pipe, the air outlet is opened at one end of the first housing, and the first sealing assembly is connected to the end of the vent pipe away from the air outlet and connected to the atomizing unit.

[0011] The inner wall of the first housing, the wall of the vent pipe, and one side of the first sealing assembly together form the first oil storage cavity. The first sealing assembly has oil passages penetrating its opposite sides, and the oil passages connect the first oil storage cavity and the second oil storage cavity.

[0012] In one embodiment, at least a portion of the wall of the oil passage is inclined toward the central axis of the oil passage in the direction from the oil storage unit to the atomizing unit, such that the diameter of the oil passage near the end of the first oil storage chamber is larger than the diameter near the end of the second oil storage chamber.

[0013] In one embodiment, the first sealing assembly has a connecting post on the side facing the atomizing unit, the connecting post being inserted into the atomizing unit, and the oil passage penetrating the connecting post.

[0014] In one embodiment, the atomizing core is a ceramic atomizing core, comprising a ceramic substrate and a heating element disposed on the ceramic substrate.

[0015] In one embodiment, the atomizing unit includes a second housing, an upper seal, and a second sealing assembly. The second housing is connected to a first housing. The upper seal is located at one end of the second housing along its own axial direction, and the second sealing assembly is located at the opposite end of the second housing along its own axial direction. The oil storage unit is connected to the upper seal, and the first air inlet penetrates the second sealing assembly. The inner wall of the second housing, the side of the upper seal away from the oil storage unit, and the side of the second sealing assembly facing the upper seal together form the second oil storage chamber.

[0016] In one embodiment, the second sealing assembly includes a lower seal and a bottom cover. One side of the lower seal forms the bottom wall of the second oil storage chamber. The bottom cover is connected to the side of the lower seal opposite to the second oil storage chamber. The bottom cover and the lower seal form an oil suction chamber communicating with the first air inlet. An oil suction element is provided in the oil suction chamber.

[0017] In one embodiment, the atomizing chamber is coaxially arranged with the air passage and the first air inlet.

[0018] In one embodiment, the second oil storage chamber is provided with an oil storage component, which fills the second oil storage chamber and wraps the atomizing core.

[0019] In one embodiment, the atomizing unit is embedded with a pin electrically connected to the atomizing core, and the power supply unit has a spring pin connected to the pin, so that the power supply unit is electrically connected to the atomizing core.

[0020] The aforementioned electronic atomizing device, by separately and detachably connecting the oil storage unit and the atomizing unit, allows for independent production and transportation of both, thus facilitating assembly. During individual transportation, simply sealing the oil storage unit with a sealing plug ensures a completely airtight oil chamber, preventing leakage even after prolonged transportation and storage. Furthermore, when the e-liquid is depleted, the atomizing unit can be reused simply by removing the oil storage unit from the atomizing unit and reassembling a new oil storage unit, eliminating the need to discard the atomizing unit after the e-liquid is used up. This not only reduces user costs but also promotes environmental friendliness and avoids waste. Attached Figure Description

Detailed Implementation

[0029] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0030] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0031] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0032] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0033] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0034] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0035] One embodiment of this application provides an electronic atomizing device for heating an atomizing medium stored inside the device to form an aerosol for a user to inhale.

[0036] The following description uses an electronic cigarette as an example to illustrate the structure of the electronic atomizing device in this application. This embodiment is only used as an example and does not limit the technical scope of this application. It is understood that in other embodiments, the electronic atomizing device of this application is not limited to an electronic cigarette, but can also be any other electronic atomizing device capable of atomizing a medium into an aerosol, which is not limited here.

[0037] See Figure 1 , Figure 1A schematic diagram of the external appearance of an electronic atomizing device 10 according to an embodiment of this application is shown. The electronic atomizing device 10 provided in one embodiment of this application includes an atomizer 100 and a power supply unit 200, wherein the atomizer 100 and the power supply unit 200 are detachably connected to each other. The power supply unit 200 supplies power to the atomizer 100, which, under the influence of the electrical energy provided by the power supply unit 200, heats the atomizing medium stored within itself, so that the atomizing medium can be atomized to generate an aerosol for the user to inhale. In the embodiments of this application, the atomizing medium can be e-liquid, or other liquids that can be heated to generate an aerosol; this is not limited thereto.

[0038] However, as described in the background section, in current traditional electronic atomization devices, the atomizer 100 is a single unit after assembly and filling with e-liquid. Although there are seals to seal the e-liquid, it is still impossible to completely prevent leakage during transportation and daily storage. Moreover, because the existing atomizers 100 are all single units, the entire atomizer 100 needs to be replaced after the e-liquid is exhausted, resulting in the atomizer coil 124 and other atomization components not being reusable, thus causing a certain amount of resource waste.

[0039] Therefore, in order to solve the above problems, the applicant conceived of designing the atomizer 100 as a detachable structure. Specifically, as shown in... Figure 2 As shown, in one embodiment, the atomizer 100 includes an oil storage unit 110 and an atomizing unit 120, which are detachably connected to each other by means of snap-fit ​​or other means. The power supply unit 200 is also detachably connected to the end of the atomizing unit 120 away from the oil storage unit 110 by means of snap-fit ​​or magnetic connection.

[0040] More specifically, such as Figure 3 As shown, the oil storage unit 110 has a first oil storage chamber 110a and an air passage 113a that are isolated from each other. The first oil storage chamber 110a stores liquid e-liquid, and one end of the oil storage unit 110 has an air outlet 111a that connects to the air passage 113a. The atomizing unit 120 is detachably connected to the end of the oil storage unit 110 away from the air outlet 111a. The atomizing unit 120 has a second oil storage chamber 120a that connects to the first oil storage chamber 110a. The second oil storage chamber 120a has an atomizing core 124 that is electrically connected to the power supply unit 200. The atomizing core 124 has an atomizing chamber 124a that connects to the air passage 113a. Figure 4 As shown, the atomizing unit 120 also has a first air inlet 120b that connects to the atomizing chamber 124a, and the power supply unit 200 has a second air inlet 201 that connects to the first air inlet 120b.

[0041] As an optional implementation, the atomizing core 124 is a ceramic atomizing core, including a ceramic substrate and a heating element disposed on the ceramic substrate. The ceramic substrate can be cylindrical or other shapes, and the interior of the ceramic substrate has a hollow cavity, which is the atomizing cavity 124a. The heating element is disposed on the cavity wall of the atomizing cavity 124a.

[0042] When the user inhales, outside air enters the atomizing chamber 124a through the second air inlet 201 and the first air inlet 120b in sequence. E-liquid flows from the first oil storage chamber 110a to the second oil storage chamber 120a, and then from the second oil storage chamber 120a to the ceramic substrate of the atomizing core 124. The heating element of the atomizing core 124 heats up and atomizes the e-liquid into an aerosol. After mixing with the outside air, the aerosol is inhaled by the user through the air passage 113a and the air outlet 111a.

[0043] It is easy to see that after the e-liquid in the first e-liquid reservoir 110a is exhausted, the e-liquid reservoir 110 can be removed from the atomizing unit 120, and then... Figure 5 As shown, a new oil storage unit 110 is installed on the atomizing unit 120, so the atomizing unit 120 can be reused without having to discard it after the e-liquid is exhausted. This not only reduces the user's cost but is also environmentally friendly and avoids waste.

[0044] The specific structures of the oil storage unit 110 and the atomizing unit 120 are described in detail below.

[0045] Combination Figure 3 and Figure 6 As shown, in one embodiment, the oil storage unit 110 includes a first housing 111 and a first sealing assembly 112. The first housing 111 is provided with a vent pipe 113, and an air passage 113a passes through the opposite ends of the vent pipe 113. An air outlet 111a is opened at one end of the first housing 111. The first sealing assembly 112 is connected to the end of the vent pipe 113 away from the air outlet 111a and is connected to the atomizing unit 120. The inner wall of the first housing 111, the wall of the vent pipe 113, and the side of the first sealing assembly 112 away from the atomizing unit 120 together form a first oil storage chamber 110a. The first sealing assembly 112 has an oil passage hole 112a that passes through its opposite sides. The oil passage hole 112a connects the first oil storage chamber 110a and the second oil storage chamber 120a, so that the e-liquid in the first oil storage chamber 110a can flow downward to the second oil storage chamber 120a through the oil passage hole 112a.

[0046] In one embodiment, one end of the vent pipe 113 is integrally connected to the first housing 111 and extends into the first housing 111. It is understood that the vent pipe 113 may also be a separate part connected to the first housing 111, which is not limited here.

[0047] Preferably, the number of oil passages 112a is at least two, and all oil passages 112a are arranged in pairs, with each pair of oil passages 112a radially distributed on both sides of the air passage 113a. By increasing the number of oil passages 112a, the e-liquid in the first oil storage chamber 110a has more paths to flow into the second oil storage chamber 120a. Therefore, when the e-liquid in the second oil storage chamber 120a is depleted, the e-liquid in the first oil storage chamber 110a can be replenished in a timely manner, preventing dry burning. Optionally, in Figure 3 In one embodiment, there are two oil passage holes 112a, which are arranged radially on both sides of the air passage 113a. In other embodiments, the number of oil passage holes 112a may be more, and there is no limitation here.

[0048] In the specific structure of the first sealing assembly 112, the first sealing assembly 112 includes a heating cap seal 1121 and a heating cap 1122. One side of the heating cap seal 1121 forms the bottom wall of the first oil storage chamber 110a. The heating cap 1122 is connected to the side of the heating cap seal 1121 opposite to the first oil storage chamber 110a. The heating cap seal 1121 has a first through hole 1121a, and the heating cap 1122 has a second through hole 1122a. The second through hole 1122a communicates with the first through hole 1121a and together form an oil passage hole 112a. The function of the heating cap seal 1121 is to seal the e-liquid in the first oil storage chamber 110a, preventing it from flowing to places other than the second oil storage chamber 120a. The heating cap 1122 is used to support the heating cap seal 1121 and to connect to the atomizing unit 120.

[0049] Preferably, the heating cap 1122 has a connecting post 1122b protruding towards the atomizing unit 120 on the side near the atomizing unit 120. The number of connecting posts 1122b corresponds to the number of oil passage holes 112a, with each oil passage hole 112a passing through a corresponding connecting post 1122b. The connecting posts 1122b are inserted into the atomizing unit 120, making the connection between the oil storage unit 110 and the atomizing unit 120 more secure and easier to install. When the oil storage unit 110 is disassembled from the atomizing unit 120 for transportation, the oil passage hole 112a can be sealed by simply placing a sealing plug on the connecting post 1122b, thus keeping the first oil storage chamber 110a completely sealed. Even after long-term transportation and storage, there will be no oil leakage or seepage, ensuring the quality of the shipped product.

[0050] Optionally, the oil passage 112a can be a straight hole, a tapered hole, or a combination of both. Preferably, as shown below... Figure 3As shown, the oil passage 112a is a combination of a conical hole and a straight hole, that is, a part of the oil passage 112a is a conical hole and the other part is a straight hole; in other words, in the direction from the oil storage unit 110 to the atomizing unit 120, at least a part of the hole wall of the oil passage 112a is inclined toward the central axis of the oil passage 112a, so that the diameter of the oil passage 112a at the end near the first oil storage chamber 110a is larger than the diameter at the end near the second oil storage chamber 120a.

[0051] By designing at least a portion of the oil passage 112a as a conical hole, the flow rate of the e-liquid can be controlled during its flow from the first oil storage chamber 110a to the second oil storage chamber 120a, preventing it from flowing too fast or too slow.

[0052] It is understood that in some other embodiments, the first sealing component 112 may also be an integrally formed structure, and there is no particular limitation. However, it is obvious that the structure designed as a combination of the heating cap seal 1121 and the heating cap 1122 can make the sealing effect better.

[0053] Please continue reading. Figure 3 and Figure 6 In one embodiment, the atomizing unit 120 includes a second housing 121, an upper seal 122, and a second sealing assembly 123. The second housing 121 is connected to the first housing 111. The upper seal 122 is located at one end of the second housing 121 along its own axial direction, and the second sealing assembly 123 is located at the opposite end of the second housing 121 along its own axial direction. The oil storage unit 110 is connected to the upper seal 122, and the first air inlet 120b passes through the second sealing assembly 123. The inner wall of the second housing 121, the side of the upper seal 122 away from the oil storage unit 110, and the side of the second sealing assembly 123 facing the upper seal 122 together form a second oil storage cavity 120a.

[0054] Optionally, the second oil storage chamber 120a is provided with an oil storage component 125 made of a fiber material that can lock and guide oil. The oil storage component 125 fills the second oil storage chamber 120a and wraps around the atomizer core 124. The oil storage component 125 can lock in the e-liquid, preventing it from flowing freely, and can also guide the e-liquid to the atomizer core 124 in a specific direction.

[0055] In a preferred embodiment, the atomizing core 124 is positioned directly below the air passage 113a, and the atomizing chamber 124a is coaxially arranged with the air passage 113a and the first air inlet 120b. This allows the airflow to flow in a straight line after entering the atomizer 100, avoiding a winding flow path. This reduces the loss of airflow and aerosol during flow, thereby ensuring a larger air output and improving the consumer's inhalation experience.

[0056] Similar to the first sealing assembly 112, the second sealing assembly 123 includes a lower sealing member 1231 and a bottom cover 1232. One side of the lower sealing member 1231 forms the bottom wall of the second oil storage cavity 120a, and the bottom cover 1232 is connected to the side of the lower sealing member 1231 away from the second oil storage cavity 120a. Both the upper seal 122 and the lower seal 1231 are used to seal the e-liquid in the second oil storage chamber 120a, so that when the electronic atomizing device 10 is upright (i.e., when the air outlet 111a is facing upwards), the e-liquid in the second oil storage chamber 120a can only flow into the atomizing core 124; when the electronic atomizing device 10 is inverted (i.e., when the air outlet 111a is facing downwards), it can only flow into the first oil storage chamber 110a, preventing the e-liquid from leaking to other locations. The bottom cover 1232 is used to support the lower seal 1231 and to connect the power supply unit 200. Its function is similar to that of the heating cover 1122 of the first sealing assembly 112, and will not be described in detail here.

[0057] Furthermore, in order to prevent the condensate generated in the atomizing chamber 124a after cooling from leaking along the first air inlet 120b into the power supply unit 200 or dripping from the second air inlet 201 into the outside of the electronic atomizing device 10, in an improved embodiment, an oil-absorbing chamber 123a communicating with the first air inlet 120b is also formed between the bottom cover 1232 and the lower seal 1231. The oil-absorbing chamber 123a is provided with an oil-absorbing element 1233 made of fiber cotton. The oil-absorbing element 1233 can also lock in oil, so it can absorb the condensate dripping from the atomizing chamber 124a and prevent the condensate from leaking into the power supply unit 200 or into the outside of the electronic atomizing device 10.

[0058] It is understood that the structure of the atomizing unit 120 is not limited to the structure described in the above embodiments. For example, in other embodiments, the atomizing unit 120 may not have a second oil storage chamber 120a and may only have an atomizing core 124. The atomizing core 124 is directly inserted into the oil storage unit 110, as long as the e-liquid in the first oil storage chamber 110a in the oil storage unit 110 can flow into the atomizing core 124.

[0059] Furthermore, in the connection structure between the atomizing unit 120 and the power supply unit 200, the atomizing unit 120 is embedded with a pin 126 electrically connected to the atomizing core 124. Specifically, the pin 126 is embedded in the bottom cover 1232 of the second sealing assembly 123. There are two pins 126, which serve as the positive and negative terminals respectively. The power supply unit 200 has two spring pins 202, which also serve as the positive and negative terminals respectively. The spring pin 202 serving as the positive terminal is connected to the pin 126 serving as the positive terminal, and the spring pin 202 serving as the negative terminal is connected to the pin 126 serving as the negative terminal, so that the power supply unit 200 is electrically connected to the atomizing core 124, thereby providing power to the atomizing core 124. Regarding the specific structure of the power supply unit 200, the power supply unit 200 includes a battery, an airflow sensor, etc., and the spring pin 202 is connected to the battery. The specific structure can be referred to in the prior art and will not be described in detail here.

[0060] Combination Figure 2 , Figure 3 and Figure 4 As shown, the electronic atomizing device 10 provided in this application is assembled according to the following steps:

[0061] First, install the heating cap seal 1121 into the heating cap 1122 to assemble it into the first sealing assembly 112; then, invert the first housing 111, inject e-liquid into the cavity of the first housing 111, and then snap the first seal into the first housing 111 to complete the assembly of the oil storage unit 110.

[0062] The second step is to press the upper seal 122 into the second housing 121 to make it a whole; then press the ejector pin 126 into the bottom cover 1232, then install the oil suction member 1233 on the bottom cover 1232, and then install the lower seal 1231 on the bottom cover 1232 to assemble it into the second sealing assembly 123; then, wrap the atomizing core 124 with the oil storage member 125 to make it a heating semi-finished product, install the heating semi-finished product on the lower seal 1231, and then connect the heating semi-finished product and the lower seal 1231 together to the whole formed by the upper seal 122 and the second housing 121 to complete the assembly of the atomizing unit 120.

[0063] The third step is to connect the atomizing unit 120 to the oil storage unit 110 to make it a complete atomizer 100.

[0064] The fourth step is to connect the atomizer 100 to the power supply unit 200 to complete the assembly of the electronic atomizing device 10.

[0065] Therefore, the electronic atomizing device 10 provided in this application has a three-section structure in which the oil storage unit 110, the atomizing unit 120, and the power supply unit 200 are connected in sequence. The oil storage unit 110 and the atomizing unit 120, as well as the atomizing unit 120 and the power supply unit 200, are connected by detachable connections, which ensures both product robustness and easy disassembly and assembly. When the e-liquid is exhausted, the oil storage unit 110 is pulled out and placed in the recycling bin, and a new oil storage unit 110 is then inserted into the atomizing unit 120 to form a new atomizer 100, which is connected to the power supply unit 200, completing the cartridge replacement process and allowing the consumer to continue vaping. During the cartridge replacement process, only the oil storage unit 110 needs to be replaced, and the atomizing unit 120 can be reused multiple times, thus reducing unnecessary resource waste and achieving green environmental protection and energy conservation.

[0066] Furthermore, the oil storage unit 110 and the atomizing unit 120 can be shipped and transported separately. During transportation, the oil storage unit 110 only needs to be sealed with a plug to keep the first oil storage chamber 110a completely sealed. Even after long-term transportation and storage, there will be no oil leakage or seepage. When it reaches the consumer, simply remove the plug and install the oil storage unit 110 into the atomizing unit 120 to form the atomizer 100 for normal vaping. It is very quick and convenient.
