Description

Technical Field

[0001] This application relates to the field of electronic cigarette technology, specifically to an electronic cigarette atomizer and electronic cigarette that can improve the utilization rate of e-liquid. Background Technology

[0002] An electronic cigarette is an electronic product used to replace traditional cigarettes. It mainly consists of an atomizer and a power supply component. The atomizer heats and vaporizes e-liquid, while the power supply component provides current to the atomizer. Existing electronic cigarettes can be divided into disposable and reusable types. In recent years, disposable electronic cigarettes with larger capacities have become more popular, requiring larger e-liquid containers in their internal design; consequently, the volume of the e-liquid reservoir also needs to increase. In an electronic cigarette, the lower end of the reservoir is connected to the heating element. During inhalation, as the e-liquid decreases, the upper portion gradually flows downwards due to gravity, allowing it to reach the heating element for vaporization.

[0003] Currently, the e-liquid reservoir in e-cigarette atomizers is mostly a one-piece structure, and the reservoir is generally fitted tightly to the inner wall of the e-liquid cup to reduce e-liquid movement and prevent leakage. This creates a relatively enclosed space inside the e-liquid cup. During inhalation, external air cannot flow into the e-liquid cup, or can only flow in a small amount, creating a negative pressure inside the cup. This obstructs the flow of e-liquid within the reservoir, preventing some e-liquid from reaching the heating element.

[0004] It is evident that existing e-cigarette atomizers have a problem with excessive e-liquid residue, resulting in low e-liquid utilization and waste; actual tests show that the e-liquid utilization rate of existing e-cigarette atomizers is generally only around 80%. Summary of the Invention

[0006] As a further improvement of this application, the oil-storing cotton is provided with a first ventilation groove on each of its left and right side walls. The first ventilation groove extends to the upper and lower end faces of the oil-storing cotton and is connected to the first ventilation hole.

[0007] As a further improvement of this application, the oil cup body includes an oil storage tube, an upper seal and a lower seal. The oil storage tube is a hollow tubular structure. The oil storage cotton is disposed inside the oil storage tube. The upper seal and the lower seal are respectively sealed to both ends of the oil storage tube. The upper seal and the lower seal abut against the oil storage cotton. One end of the air passage tube extending out of the oil storage cotton is connected to the upper seal.

[0008] As a further improvement of this application, the upper sealing member has an air passage groove on the end face near the oil storage cotton. The first vent hole is located at the corresponding position of the air passage pipe and the air passage groove. The first vent hole is connected to the air passage groove. The left and right side walls of the air passage groove are respectively provided with a first notch, and the first notch is connected to the first vent groove.

[0009] As a further improvement of this application, the lower seal is provided with a first mounting groove on the end face near the oil storage cotton, and the left and right side walls of the first mounting groove are respectively provided with second notches, which are respectively connected to the corresponding first vent grooves.

[0010] As a further improvement of this application, the first mounting groove is provided with a limiting post and a first oil-separating cotton. The first oil-separating cotton is provided with a mounting hole. The diameter of the mounting hole is adapted to the limiting post. The limiting post passes through the mounting hole. The first oil-separating cotton abuts against the inner end face of the first mounting groove.

[0011] As a further improvement of this application, the first oil-separating cotton is provided with two third notches, which are symmetrically distributed on both sides of the mounting hole, and the third notches are respectively connected to the corresponding second notches.

[0012] As a further improvement of this application, the upper sealing member is provided with a second mounting groove on the end face away from the oil storage cotton, the second mounting groove is provided with a second oil separating cotton, the second oil separating cotton is provided with a second vent hole, and the second vent hole is connected to the air passage and the suction nozzle respectively.

[0013] As a further improvement of this application, the heating element includes a heating wire support, a heating wire, and an oil-guiding cotton. One end of the heating wire support is connected to the airway tube, and the other end is connected to the lower seal. The heating wire and the oil-guiding cotton are respectively connected to the heating wire support, and the oil-guiding cotton is connected to the oil-storing cotton.

[0014] On the other hand, this application also provides an electronic cigarette, including the above-mentioned electronic cigarette atomizer that can improve the utilization rate of e-liquid, wherein a power supply component is provided inside the housing, and the power supply component is electrically connected to the heating core.

[0015] Compared with the prior art, the beneficial effects of this application are: This application connects the e-liquid storage chamber to the inner cavity of the airway tube by providing a first vent hole on the side wall of the airway tube. The airway tube, in turn, connects to the mouthpiece, thus linking the e-liquid storage chamber to the mouthpiece and, consequently, to external air. As e-liquid decreases, a negative pressure is created within the storage chamber, obstructing e-liquid flow. External air then flows into the airway tube through the mouthpiece and into the storage chamber through the first vent hole, balancing the air pressure inside and outside the storage chamber. This allows the e-liquid to flow smoothly within the storage chamber, reducing e-liquid residue in the e-liquid reservoir. Therefore, this application reduces e-liquid residue in the reservoir, improves e-liquid utilization, and enhances user experience. Actual testing shows that the e-liquid utilization rate of the electronic cigarette atomizer provided by this application is 3%-10% higher than existing technologies. Attached Figure Description

The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment to other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0020] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0021] like Figure 1-5 As shown, an electronic cigarette atomizer that improves e-liquid utilization is disclosed. This atomizer is installed on an electronic cigarette, which includes a power supply component electrically connected to the atomizer. The power supply component provides power to the atomizer, enabling it to heat and atomize the e-liquid. The electronic cigarette atomizer includes a housing 1, within which the power supply component is installed. The housing 1 also contains an e-liquid cup assembly and an atomizing assembly. The e-liquid cup assembly is connected to the atomizing assembly and serves to store the e-liquid. The atomizing assembly heats and atomizes the e-liquid. When the electronic cigarette is in operation, e-liquid flows from the e-liquid cup assembly onto the atomizing assembly. The power supply component outputs current to the atomizing assembly, which heats and atomizes the e-liquid into an aerosol for the user to inhale.

[0022] The oil cup assembly includes an oil cup body, within which an oil storage chamber 2 is provided, and an integrated oil storage cotton 3 is provided within the oil storage chamber 2. The oil cup body is used to hold e-liquid, and the integrated oil storage cotton 3 is provided within the oil cup body to prevent the e-liquid from shaking within the oil cup body, thereby reducing the possibility of e-liquid leakage. The atomizing assembly includes a heating core and an air duct 4. A mouthpiece 101 is provided at the upper end of the shell 1. The air duct 4 is a hollow tubular structure. The oil storage cotton 3 has an installation through hole 31 that penetrates the upper and lower ends of the oil storage cotton 3. The heating core and the air duct 4 are respectively limited within the installation through hole 31, and the heating core is connected to the oil storage cotton 3, thereby facilitating the introduction of smoke from the oil storage cotton 3 into the heating core. One end of the air duct 4 is fixedly connected to the heating core, and the other end of the air duct 4 extends out of the oil storage cotton 3 and is connected to the mouthpiece 101. A first vent hole 41 is provided on the side wall of the end of the air duct 4 extending out of the oil storage cotton 3, and the first vent hole 41 is connected to the oil storage chamber 2. The heating element is electrically connected to the power supply component. When the e-cigarette is in use, the e-liquid flows from the oil storage cotton 3 into the heating element. The user inhales through the mouthpiece 101 to start the e-cigarette. The power supply component supplies power to the heating element, causing the heating element to work and atomize the e-liquid into an aerosol. The atomized smoke flows sequentially with the user's inhalation airflow to the airway tube 4 and the mouthpiece 101, and is finally inhaled by the user, completing the e-cigarette inhalation process.

[0023] This electronic cigarette atomizer connects the oil storage chamber 2 to the inner cavity of the airway tube 4 via a first vent 41 on the side wall of the airway tube 4. The airway tube 4 is also connected to the mouthpiece 101, thus connecting the oil storage chamber 2 to the mouthpiece 101 and, consequently, to the external air. As the e-liquid decreases, a negative pressure is generated in the oil storage chamber 2, obstructing the flow of e-liquid. External air then flows into the airway tube 4 through the mouthpiece 101 and into the oil storage chamber 2 through the first vent 41, thereby balancing the air pressure inside and outside the oil storage chamber 2. This allows the e-liquid in the oil storage chamber 2 to flow smoothly, reducing e-liquid residue in the oil storage cotton 3 and improving the utilization rate of e-liquid.

[0024] In this embodiment, there are two first vent holes 41, and the two first vent holes 41 are symmetrically distributed along the central axis of the airway tube 4, that is, the line connecting the centers of the two first vent holes 41 intersects the central axis of the airway tube 4.

[0025] The oil-collecting cotton 3 has two first ventilation grooves 32 on its left and right side walls, extending to the upper and lower ends of the oil-collecting cotton 3 respectively. The two first ventilation grooves 32 are symmetrically distributed along the center of the oil-collecting cotton 3 and are connected to the first ventilation holes 41. By setting the first ventilation grooves 32 and connecting them to the first ventilation holes 41, when external gas flows into the oil-collecting cavity 2 from the first ventilation holes 41, it will flow into the first ventilation grooves 32, thereby allowing air circulation at both ends of the oil-collecting cotton 3. The first ventilation grooves 32 can improve the air circulation efficiency within the oil-collecting cotton 3, thereby further accelerating the air pressure balance inside and outside the oil-collecting cavity 2 and reducing e-liquid residue.

[0026] The oil cup body includes an oil storage tube 5, an upper seal 6, and a lower seal 7. The oil storage tube 5 is a hollow tubular structure, and an oil storage cotton 3 is placed inside the oil storage tube 5. The upper seal 6 and the lower seal 7 are respectively sealed to both ends of the oil storage tube 5 and respectively abut against the oil storage cotton 3. One end of the air passage tube 4 extends out of the oil storage cotton 3 and is connected to the upper seal 6. The upper seal 6 and the lower seal 7 are made of silicone material and are used to seal both ends of the oil storage tube 5, thereby forming a closed oil storage cavity 2 inside the oil storage tube 5.

[0027] The heating element includes a heating wire support 8, a heating wire 9, and an oil-wicking cotton 10. One end of the heating wire support 8 is fixedly connected to the airway tube 4, and the other end is fixedly connected to the lower seal 7. The heating wire 9 and the oil-wicking cotton 10 are respectively mounted on the heating wire support 8. The oil-wicking cotton 10 is connected to the oil-retaining cotton 3, and the heating wire 9 is electrically connected to the power supply component. During inhalation, e-liquid flows from the oil-retaining cotton 3 onto the oil-wicking cotton 10. When the user inhales through the mouthpiece 101, a start signal is triggered, causing the power supply component to output current to the heating wire 9. The heating wire 9 heats and atomizes the e-liquid. The atomized aerosol flows with the user's inhalation airflow to the airway tube 4, then to the mouthpiece 101, and is finally inhaled by the user, completing the inhalation process.

[0028] An air passage groove 61 is provided on the end face of the upper sealing member 6 near the oil storage cotton 3. In this embodiment, the first vent hole 41 is located at the corresponding position of the air passage pipe 4 and the air passage groove 61, and the first vent hole 41 is connected to the air passage groove 61. The left and right side walls of the air passage groove 61 are respectively provided with first notches 62, and the first notches 62 are respectively connected to the first vent groove 32. By setting the air passage groove 61, a certain gap can exist between the upper part of the oil storage cotton 3 and the upper sealing member 6, so that external air can flow into the oil storage cavity 2 from the first vent hole 41. The first notch 62 is set so that the air passage groove 61 can be connected to the first vent groove 32, so that the air flowing in from the first vent hole 41 can flow into the first vent groove 32, thereby allowing air circulation at both ends of the oil storage cotton 3, balancing the air pressure difference inside and outside the oil storage cavity 2, and allowing the e-liquid in the oil storage cotton 3 to flow smoothly.

[0029] The lower seal 7 has a first mounting groove 71 on its end face near the oil-collecting cotton 3. A limiting post 72 and a first oil-separating cotton 11 are disposed within the first mounting groove 71. The first oil-separating cotton 11 has a mounting hole 111, the diameter of which is adapted to the limiting post 72. When installing the first oil-separating cotton 11, it is fitted onto the limiting post 72 by aligning the mounting hole 111 and the limiting post 72, allowing the limiting post 72 to pass through the mounting hole 111 until the first oil-separating cotton 11 abuts against the inner end face of the first mounting groove 71, thus placing the first oil-separating cotton 11 onto the lower seal 7. During daily use, e-liquid flows downwards automatically due to its own gravity, causing the lower seal 7 to constantly bear significant e-liquid pressure. Therefore, there is a considerable risk of oil leakage on the lower seal 7. The first oil-separating cotton 11 absorbs the e-liquid, thereby reducing the possibility of leakage from the lower seal 7.

[0030] Meanwhile, in order to facilitate the smooth flow of e-liquid within the oil storage chamber 2, in this embodiment, second notches 73 are respectively provided on the left and right side walls of the first mounting groove 71, and the second notches 73 are respectively connected to the first venting groove 32. Two third notches 112 are provided on the first oil-separating cotton 11, and the two third notches 112 are symmetrically distributed on both sides of the mounting hole 111, and the third notches 112 are respectively connected to the corresponding second notches 73. By setting the second notch 73 and the third notch 112, the first vent 41, the air passage 61, the first air passage 32, the second notch 73 and the third notch 112 form a passage. In daily use, this ensures that external air flows fully into the oil storage chamber 2 and then into the upper and lower ends of the oil storage cotton 3, so that the air pressure inside and outside the oil storage chamber 2 is balanced, preventing the formation of air pressure difference and ensuring that the e-liquid flows smoothly inside the oil storage chamber 2. The oil storage cotton 3 has the function of absorbing e-liquid. Under the premise of smooth e-liquid flow, the oil storage cotton 3 can absorb as much e-liquid as possible and output it to the heating core for heating and atomization, thereby reducing the e-liquid residue in the oil storage chamber 2 and improving the utilization rate of e-liquid.

[0031] A second mounting groove 63 is provided on the end face of the upper sealing member 6 away from the oil-absorbing cotton 3. A second oil-separating cotton 12 is provided in the second mounting groove 63, and a second vent hole 121 is provided on the second oil-separating cotton 12. The second vent hole 121 is connected to the airway tube 4 and the mouthpiece 101 respectively. During the transportation or carrying of e-cigarettes, there is a risk of e-liquid leakage from the mouthpiece 101. The second oil-separating cotton 12 at the upper end of the upper sealing member 6 can absorb the e-liquid flowing from the airway tube 4 to the mouthpiece 101, thereby reducing the possibility of e-liquid leakage from the mouthpiece 101. At the same time, during the inhalation process, the oil-separating cotton can also absorb the e-liquid that is not fully atomized and impurities, improving the taste of e-cigarettes. Moreover, the second oil-separating cotton 12 is located below the mouthpiece 101, which can also reduce the generation of condensate and improve the user experience.

[0032] To fully demonstrate the beneficial effects of this application, the applicant conducted the following comparative experiments using a suction testing machine to compare the prior art and the atomizer provided in this application: The experimental parameters of the suction tester are: 2 seconds of suction and 8 seconds of pause, suction volume of 35 ml / time, and suction flow rate of 17.5 ml / s. All experimental data are obtained by stopping suction when a burnt smell is detected. In this experiment, 5 products from the prior art and this application were randomly selected for testing.

[0033] The experimental results are shown in the table below: In the above table: Residual oil mass of oil-absorbing cotton = mass of wet cotton after extraction - mass of dry cotton; E-liquid utilization rate = (filled e-liquid mass - residual e-liquid mass in e-liquid storage cotton) / filled e-liquid mass * 100%.

[0034] The experimental results above show that using the electronic cigarette atomizer provided in this application can improve the e-liquid utilization rate by 3%-10%.

All equivalent changes made in accordance with this application are within the protection scope of this application.
