Description

Technical Field

[0001] This application relates to the field of electronic atomizing devices, and in particular to electronic atomizing devices with a leak-proof structure. Background Technology

[0002] Electronic atomizing devices consist of a power supply, a heating element, and an atomizer. The atomizer stores the atomizing structure. Users often carry these devices in their pockets or bags, and they are transported from one location to another as the user moves. If the atomizing medium leaks during this process, it will significantly impact the user experience. Incorrect installation, temperature changes, and damage to the coil or components of the heating element can all cause atomizing medium leakage. Therefore, it is impossible to predict or prevent leaks before they occur. Leaked atomizing medium flows down the cavity of the electronic atomizing device and exits through the air inlet, remaining outside the device. If a leak occurs during large-scale transportation, the atomizing medium can form an aerosol upon heating, and a large-scale leak could even cause a fire, posing a significant safety hazard. Summary of the Invention

[0003] To address the aforementioned technical problems, this application provides an oil leakage prevention structure that enables timely handling of atomized media that has been adsorbed and leaked, thus solving the problem that existing atomized media leaks cannot be handled in a timely manner.

[0004] One technical solution proposed in this application is to provide an oil-proof structure for use in an electronic atomizing device. The oil-proof structure includes an oil-blocking body and at least one oil-guiding groove disposed on the oil-blocking body. The oil-guiding groove is arranged around the oil-blocking body.

[0005] Specifically, there are several oil guide grooves, each of which is an annular groove surrounding the oil blocking body, and the oil guide grooves are arranged along the height direction of the oil blocking body.

[0006] Specifically, each of the oil guide grooves has the same width; or, each of the oil guide grooves has the same depth; or, each of the oil guide grooves has the same width and depth.

[0007] Specifically, the interval between adjacent oil guide grooves is equal.

[0008] Specifically, the oil blocking body is also provided with an air guiding channel; the air guiding channel is connected to the oil guiding groove.

[0009] Specifically, the air guide channel is a straight groove extending along the height direction of the oil blocking body, and the air guide channel passes through the oil guide groove to connect the oil guide groove.

[0010] Specifically, the oil-blocking body is a hollow columnar body, including a hollow through hole; the air guiding channel penetrates the wall of the oil-blocking body and communicates with the hollow through hole.

[0011] An electronic atomizing device is proposed, characterized in that the electronic cigarette includes any of the above-mentioned leak-proof structures.

[0012] Specifically, the electronic atomizing device includes an atomizer and a smoke channel, the smoke channel being connected to the atomizer, and the leak-proof structure being installed inside the smoke channel.

[0013] Specifically, a power supply device is also provided inside the smoke channel, the power supply device is connected to the atomizer, and the oil-blocking body surrounds the power supply device.

[0014] The beneficial effects of this application are as follows: Compared with existing oil-proof structures, the oil-proof structure proposed in this application includes an oil-blocking body and at least one oil-guiding groove disposed on the body, with the oil-guiding groove surrounding the oil-blocking body. Therefore, when the atomizing medium leaks, the atomizing medium drips and is adsorbed onto the oil-blocking body, where it is absorbed, preventing the atomizing medium from leaking into the circuit components and control unit, thus avoiding damage to the electronic atomizing device and affecting its lifespan. Furthermore, the oil-guiding groove surrounding the oil-blocking body increases the contact area between the oil-blocking body and the atomizing medium, further improving the oil-blocking body's adsorption capacity for the atomizing medium, enabling the oil-blocking body to adsorb leaked atomizing medium promptly and quickly.

[0022] Reference Figure 1 and Figure 2 , Figure 1 This is a schematic front view of an embodiment of an oil leak prevention structure provided in this application; Figure 2 yes Figure 1 A three-dimensional structural schematic diagram of an embodiment of an oil-proof structure. In one aspect, this application provides an oil-proof structure for use in an electronic atomizing device. In one embodiment, the oil-proof structure includes an oil-blocking body 1 and at least one oil-guiding groove 2 disposed on the oil-blocking body 1. The oil-guiding groove 2 is disposed around the oil-blocking body 1.

[0023] When atomizing medium leaks, the oil-blocking body 1 can promptly absorb the leaked atomizing medium, preventing it from flowing into the circuit components and control unit, thus avoiding damage to the electronic atomizing device and affecting its lifespan. The oil guide groove 2 increases the contact area between the atomizing medium and the oil-blocking body 1. When the electronic atomizing device experiences a media leak, the oil-blocking body 1 can absorb the atomizing medium, resolving the safety hazards caused by leakage and optimizing the user experience.

[0024] Specifically, there are several oil guide grooves 2, each of which is an annular groove surrounding the oil blocking body 1, and the oil guide grooves 2 are arranged along the height direction of the oil blocking body 1. That is to say, these oil guide grooves 2 are not interconnected and are arranged along the height direction of the oil blocking body 1. Each oil guide groove 2 is an annular groove, and the annular groove surrounds and is formed on the wall surface of the oil blocking body 1.

[0025] Understandably, in other embodiments, the oil guide groove 2 may be a strip structure arranged along the height direction of the oil blocking body 1, that is, the oil guide groove 2 is a strip groove extending in a vertical direction. Furthermore, the length of these strip structure oil guide grooves 2 does not exceed the height of the oil blocking body 1.

[0026] Specifically, in one particular embodiment, each oil guide groove 2 has an equal width.

[0027] Specifically, in another specific embodiment, each oil guide groove 2 has the same depth.

[0028] Specifically, in yet another specific embodiment, each oil guide groove 2 has the same width and depth.

[0029] Understandably, the width and / or depth of the oil guide groove 2 are equal, which facilitates the processing and forming of the leak-proof oil structure of this application. It should be noted that the depth of each oil guide groove 2 should be less than the thickness of the oil-blocking body 1. That is, the bottom surface of the oil guide groove 2 is always on the oil-blocking body 1, and does not penetrate it. This prevents leakage of the atomizing medium when the depth of the oil guide groove 2 exceeds the thickness of the oil-blocking body 1, i.e., when the oil guide groove 2 penetrates the oil-blocking body 1. In this case, the atomizing medium would flow down from the gap between the oil-blocking body 1 and the oil guide groove 2, and then into the circuit components and control unit, damaging the electronic atomizing device and affecting its lifespan.

[0030] Specifically, in other embodiments, the spacing between any two adjacent oil guide grooves 2 is equal. The uniformly distributed oil guide grooves 2 ensure that regardless of the form or state of the electronic atomizing device, if leakage of the atomizing medium occurs, the oil blocking body 1 can absorb the atomizing medium to the greatest extent possible.

[0031] More specifically, the oil guide grooves 2 are evenly distributed along the height direction of the oil blocking body 1.

[0032] Understandably, when a leak occurs, the atomizing medium flows sequentially through the oil guide grooves 2, which are arranged along the height of the oil-blocking body 1, until it is completely absorbed. The uniform distribution of the oil guide grooves 2 along the height of the oil-blocking body 1 ensures that the atomizing medium can be completely absorbed in all states, further guaranteeing against leakage and avoiding safety hazards caused by leakage.

[0033] Please continue to refer to Figure 2 , Figure 2 yes Figure 1 A three-dimensional structural diagram of an embodiment of the leak-proof oil structure is shown. Specifically, to facilitate air intake for the electronic atomizing device, an air guide channel 3 is also provided on the oil-blocking body 1; the air guide channel 3 connects to the oil guide groove 2. When the electronic atomizing device is operating, the gas entering from the air inlet (not shown) smoothly and continuously enters the electronic atomizing device through the air guide channel 3 on the oil-blocking body 1, ensuring smooth atomization of the atomizing medium.

[0034] Understandably, the width of the airflow channel 3 should be slightly greater than the width of each e-liquid groove 2, and the depth of the airflow channel 3 should also be slightly greater than the depth of each e-liquid groove 2. When a user uses an e-cigarette, they inhale through the mouthpiece, and the airflow enters the e-cigarette through the air inlet (not shown in the figure). Since the e-liquid grooves 2 are connected to the airflow channel 3, when the airflow enters the e-cigarette, it will inevitably be diverted as it passes through each e-liquid groove 2. However, when the width and depth of the airflow channel 3 are both greater than the width and depth of the e-liquid grooves 2, it ensures that even when the airflow is diverted by the e-liquid grooves 2 after entering the airflow channel 3, the airflow within the airflow channel 3 remains unobstructed. This, in turn, affects the degree to which the atomization structure within the e-cigarette atomizes the atomizing medium, reducing the generation of condensate.

[0035] In one specific embodiment, the air guide channel 3 is a straight groove extending along the height direction of the oil-blocking body 1, and the air guide channel 3 passes through each oil guide groove 2, thus connecting all the oil guide grooves 2. Since the air guide channel 3 is a straight groove along the height direction of the oil-blocking body 1, the distance of airflow is shortened, allowing the airflow to reach the sensing element more quickly when the user inhales from the mouthpiece. The sensing element then activates the power supply to power the atomizing structure, forming an aerosol more quickly at the atomizing structure, thereby improving the user experience.

[0036] Furthermore, the air guide channel 3 is designed as a straight channel that passes through the oil guide channel 2. When gas enters the leak-proof structure, the oil guide channel 2 also serves to release gas obstructions. This prevents the user from inhaling excessive gas, causing the gas flow rate to slow down too much, resulting in uneven airflow, incomplete atomization of the atomizing medium, and the generation of condensate.

[0037] Optionally, in another embodiment, the air guide channel 3 can also be configured as a curved channel with a certain curvature extending along the height direction of the oil-blocking body 1. Compared to a straight channel, a curved channel provides a more gentle channel structure for airflow. When the gas flow rate is too fast due to differences in the user's suction force, the curved channel can more effectively alleviate the airflow obstruction and achieve the appearance of maximizing atomization, making suction smoother and more comfortable.

[0038] More specifically, the oil-blocking body 1 is a hollow cylindrical body, including a hollow through-hole 7. The gas guiding channel 3 penetrates the wall of the oil-blocking body 1 and communicates with the hollow through-hole 7. The hollow through-hole 7 is a through-slot opened along the axial direction of the oil-blocking body 1. It can be understood that the setting of the hollow through-hole 7 makes the oil-blocking body 1 not a closed hollow cylindrical body, but a cylindrical arc plate structure.

[0039] The oil-blocking body 1 is an arc plate structure with a through groove, which makes the oil leakage prevention structure of this application easier to process and saves costs.

[0040] In another specific embodiment, the oil-blocking body 1 is a hollow cylindrical body, including a hollow through hole 7; each oil guide groove 2 is an annular groove arranged around the oil-blocking body 1, and the oil guide grooves 2 are evenly distributed along the height direction of the oil-blocking body 1. It can be understood that since the oil-blocking body 1 is an arc plate structure, the oil guide grooves 2 surrounding the oil-blocking body 1 are all arc-shaped grooves with the same curvature as the oil-blocking body 1.

[0041] Specifically, the oil-blocking body 1 is liquid-blocking cotton. The liquid-blocking cotton, as the oil-blocking body 1, is placed under the atomizing device to absorb the atomizing medium leaked during normal operation or transportation of the electronic atomizing device. Compared to other oil-blocking materials such as fiberglass oil-guiding ropes, stainless steel mesh, or stainless steel ropes, liquid-blocking cotton, being made of cotton, has advantages such as greater ease of use, safety, and a richer flavor.

[0042] In one specific embodiment, the liquid-blocking cotton is made of EVA cotton (a copolymer resin of ethylene and vinyl acetate formed by foaming). EVA cotton is a new type of environmentally friendly material with excellent cushioning and shock resistance, and superior sound insulation, which can reduce noise problems during the operation of electronic atomization devices. EVA cotton also has advantages such as heat insulation, waterproofing, and chemical corrosion resistance, and is non-toxic and non-hygroscopic, making it an advantageous material as a new type of liquid-blocking cotton.

[0043] Another aspect of this application provides an electronic atomizing device that includes the aforementioned leak-proof structure.

[0044] Please refer to Figure 3 , Figure 3 This is a cross-sectional schematic diagram of an electronic atomizing device provided in this application. In one embodiment, the electronic atomizing device includes an atomizer 4 and a smoke channel 5, the smoke channel 5 being connected to the atomizer 4, and an oil leakage prevention structure being installed inside the smoke channel 5. The smoke channel 5 is a buffer channel for airflow and / or aerosol located between the air inlet (not shown) of the electronic atomizing device and the atomizer 4.

[0045] When the electronic atomizer is working, the user inhales through the mouthpiece, and the airflow enters through the air inlet of the electronic atomizer (not shown in the figure, but can be set to specific dimensions). Figure 3 The air enters the electronic atomizing device (bottom shown) and passes through the smoke channel 5 and the leak-proof structure installed within the smoke channel 5 before entering the atomizer 4. Under heating conditions, the atomizer 4 atomizes the atomizing medium into an aerosol. The substance inhaled by the user through the mouthpiece is this aerosol. When the electronic atomizing device is in use, if the airflow velocity is too fast or the components within the device are not sensitive enough, the atomizer 4 may not completely atomize the medium, resulting in condensate dripping into the smoke channel 5. In this case, the oil-blocking body 1 and the oil-guiding groove 2 within the leak-proof structure of the smoke channel 5 can also absorb the condensate. This prevents condensate residue from remaining on the body of the electronic atomizing device, which would cause the device to heat up during operation and thus affect its lifespan.

[0046] Specifically, in one embodiment, a power supply device 6 is also provided within the smoke channel 5. The power supply device 6 is connected to the atomizer 4, and the oil-blocking body 1 surrounds the power supply device 6. It is understood that the oil-blocking body 1 includes a hollow through-hole 7, and the power supply device 6 is disposed within the hollow through-hole 7. The inner diameter of the hollow through-hole 7 should be slightly larger than the outer diameter of the power supply device 6, allowing the oil-blocking body 1 to surround the outside of the power supply device 6 without gaps. This prevents condensate dripping from the electronic atomizing device during normal operation and / or atomizing medium dripping due to improper installation from overflowing along the gap between the power supply device 6 and the oil-blocking body 1 to the outside of the electronic atomizing device, causing inconvenience to the user. Optionally, the power supply device 6 is a disposable battery or a rechargeable battery.

[0047] The leak-proof structure of this application includes an oil-blocking body 1 and at least one oil-guiding groove 2 disposed on the oil-blocking body 1. During the transportation of the electronic atomizing device, the oil-guiding groove 2 surrounds the oil-blocking body 1. When the atomizing medium leaks, the atomizing medium drips and is absorbed by the oil-blocking body 1, preventing the atomizing medium from leaking into the circuit components and control unit, thus avoiding damage to the electronic atomizing device and affecting its lifespan. Furthermore, the oil-guiding groove 2 surrounding the oil-blocking body 1 increases the contact area between the oil-blocking body 1 and the atomizing medium, further improving the adsorption capacity of the oil-blocking body 1 for the atomizing medium, enabling the oil-blocking body 1 to absorb leaked atomizing medium in a timely and rapid manner.
