Description

Technical Field

[0001] This application relates to the field of electronic atomizers, and in particular to bottom-fill disposable electronic atomizers. Background Technology

[0002] An electronic cigarette is an electronic device that works by heating e-liquid through a heater, which then vaporizes the e-liquid to produce vapor. Users obtain nicotine or other chemicals by inhaling this vapor without burning tobacco, thus serving as a tobacco substitute. At the same time, different flavorings can be added to the e-liquid to enhance the user's electronic cigarette experience.

[0003] There is currently a disposable electronic atomizer on the market, mainly composed of a battery, an atomizing unit, pre-filled e-liquid, and a pneumatic switch. The battery powers the device, the atomizing unit heats the e-liquid containing nicotine and flavoring to produce vapor, and the pneumatic switch is automatically activated by inhalation. Its advantages include a disposable design that eliminates the need for charging and refilling, a lightweight and portable body, and the ability to meet smoking cessation needs through a variety of flavors and tar-free characteristics, while avoiding the secondhand smoke problems associated with traditional cigarettes.

[0004] In existing disposable e-cigarettes, there is usually an e-liquid filling chamber on the shell, or a chamber inside the shell for placing the e-liquid cartridge, so that the e-liquid can enter the atomizing part during the user's inhalation. The overall assembly process is relatively complicated, which results in a relatively high production cost for disposable e-cigarettes (i.e., the e-liquid in the e-cigarette can be discarded after use), and there is room for improvement. Utility Model Content

[0005] In order to reduce production costs without affecting the user's experience, this application provides a bottom-filled disposable electronic atomizer.

[0006] The bottom-filling disposable electronic atomizer provided in this application adopts the following technical solution:

[0007] A bottom-filled disposable electronic atomizer includes a housing, a flue, an atomizing unit, and a battery. The housing is internally divided into a first chamber and a second chamber. The first chamber is used to contain e-liquid. The battery is disposed in the second chamber. The flue is located in the first chamber. The housing has an inhalation port. The atomizing unit is disposed in the flue, which is connected to the inhalation port. An e-liquid injection needle is disposed along the connection between the first chamber and the second chamber. One end of the injection needle is connected to the first chamber, and the other end of the injection needle extends toward the end face of the housing away from the inhalation port.

[0008] By adopting the above technical solution, an innovative structure is achieved by using a first chamber, a second chamber, and an oil injection needle extending from the bottom of the shell to directly inject oil from the bottom of the shell. Compared with the method of using a separate installation of the cartridge, this application does not require disassembling the shell and can inject oil into the first chamber through the oil injection needle, saving materials and production steps, and meeting the cost reduction requirements of disposable products.

[0009] Preferably, a partition plate is provided between the first chamber and the second chamber, and a through hole is provided on the partition plate, the through hole connecting the first chamber and the second chamber, and the size of the oil injection needle tube and the tolerance of the through hole are interference fit.

[0010] By adopting the above technical solution, the shell is divided into a first chamber and a second chamber by using a partition plate, so that the two form relatively independent spaces. Moreover, the volume of the first chamber and the second chamber can be adjusted by adjusting the position of the partition plate along the shell according to the usage requirements and actual design requirements. The interference fit helps to prevent the e-liquid in the first chamber from flowing into the second chamber through the through hole.

[0011] Preferably, a sealing element is provided at one end of the oil injection needle tube near the end face of the housing.

[0012] By adopting the above technical solution, after the oil is injected into the first chamber through the oil injection needle, the end of the oil injection needle is sealed with a sealing element to prevent the e-liquid from leaking out of the oil injection needle.

[0013] Preferably, the partition plate is provided with ventilation holes.

[0014] By adopting the above technical solution, the vent connects the first chamber and the second chamber, thereby balancing the air pressure inside the first chamber and the second chamber, improving the smoothness of the e-liquid flowing from the first chamber to the atomizing part. At the same time, because the air pressure in the first chamber and the second chamber is in a balanced state, the presence of air bubbles in the e-liquid is effectively reduced, which to some extent solves the probability of the atomizing part burning dry or uneven atomization caused by air bubbles mixed in with the e-liquid.

[0015] Preferably, a sealing assembly is provided between the first chamber and the partition plate, the sealing assembly being used to restrict the flow of e-liquid located in the first chamber to the second chamber.

[0016] By adopting the above technical solution, the sealing component further prevents the e-liquid in the first chamber from flowing into the second chamber, thereby improving the overall sealing performance and reducing the outflow of e-liquid.

[0017] Preferably, a first step is provided on the inner wall of the housing near the first chamber, and when the sealing assembly is located in the first chamber, the sealing assembly abuts against the first step.

[0018] By adopting the above technical solution, the first step provides an installation positioning reference for the sealing component, so that it can be accurately installed in the designated position of the housing during the assembly process. Through the cooperation of the first step and the partition plate, the sealing component is restricted between the first step and the partition plate, without the need for other mechanical structures to fix the sealing component, which makes the operation simple.

[0019] Preferably, a one-way valve is provided inside the vent hole.

[0020] By adopting the above technical solution, air is allowed to enter the first chamber in one direction, but the e-liquid or atomized e-liquid is restricted from flowing back into the second chamber, which also effectively reduces the probability of foreign objects in the second chamber entering the first chamber.

[0021] Preferably, the housing is a transparent housing.

[0022] By adopting the above technical solution, users can directly observe the amount of e-liquid remaining in the first chamber, which makes it easier to quickly detect whether there is oil leakage or improper installation of parts during the assembly process, and also helps to improve the overall appearance quality.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. This application does not require disassembly of the shell; oil can be injected into the first chamber through the oil injection needle, saving materials and production steps, and meeting the cost reduction requirements of disposable products.

[0025] 2. After the e-liquid is injected into the first chamber through the e-liquid injection needle, the end of the e-liquid injection needle is sealed with a sealing element to prevent e-liquid from leaking out of the e-liquid injection needle;

[0026] 3. The sealing assembly is confined between the first step and the partition plate through the cooperation of the first step and the partition plate, without the need for other mechanical structures to fix the sealing assembly, which makes the operation simple. Attached Figure Description

[0033] The terms "up," "down," "left," "right," "front," "rear," "side," "above," and "below" mentioned or potentially used in this specification are defined relative to the construction shown in the accompanying drawings. The terms "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively. These are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directions should not be interpreted as restrictive terms.

[0034] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0035] This application discloses a bottom-filled disposable electronic atomizer. (See also...) Figures 1-4 The bottom-filled disposable electronic atomizer includes a housing 1, a flue 2, an atomizing part 3, and a battery 4. The housing 1 is divided into a first chamber 5 and a second chamber 6. The first chamber 5 is used to hold e-liquid, the battery 4 is located in the second chamber 6, the flue 2 is located in the first chamber 5, and the housing 1 has a sucking port 7. When the electronic atomizer is working, the user's mouth contacts the sucking port 7. The atomizing part 3 is located in the flue 2, which is connected to the sucking port 7, so that the e-liquid atomized by the atomizing part 3 can be inhaled. An e-liquid injection needle 8 is provided along the connection between the first chamber 5 and the second chamber 6. One end of the e-liquid injection needle 8 is connected to the first chamber 5, and the other end of the e-liquid injection needle 8 extends towards the end face of the housing 1 away from the sucking port 7.

[0036] First, it should be noted that the atomizing part 3 is a conventional component used for atomizing e-liquid. Meanwhile, the battery 4 is used to power the atomizing part 3 and is a conventional storage battery 4. The battery 4 is installed in the second chamber 6 to improve the stability of the battery 4 installed in the housing 1. The specific composition and working principle of both will not be described in detail here.

[0037] For details, please refer to... Figure 5The shell 1 is integrally molded by injection molding, eliminating the need for secondary assembly and improving production efficiency. The shell 1 is transparent; in this embodiment, it is made of PCTG material (high-performance copolyester). Utilizing the advantages of PCTG material—high transparency, environmental safety, ease of injection molding, and excellent toughness—the user can directly observe the remaining e-liquid in the first chamber 5, enhancing the user experience. It also facilitates quick detection of leaks or improper component installation during assembly, and improves the overall appearance.

[0038] Furthermore, a partition plate 9 is provided between the first chamber 5 and the second chamber 6, dividing the interior of the housing 1 to form the first chamber 5 and the second chamber 6. The partition plate 9 has a through hole 10 connecting the first chamber 5 and the second chamber 6. The dimensions of the oil injection needle tube 8 are interference-fitted with the through hole 10. The dimensional tolerances of the partition plate 9 are transition-fitted with the internal dimensional tolerances of the housing 1. During assembly, the partition plate 9 is inserted from the end closest to the second chamber 6, and pressure is applied to install it between the first chamber 5 and the second chamber 6. Additionally, to improve the stability of the partition plate 9 when installed in the housing 1, adhesive can be applied between the partition plate 9 and the housing 1.

[0039] Correspondingly, since the tolerance fit between the oil injection needle tube 8 and the through hole 10 is an interference fit, the shell 1 is divided into a first chamber 5 and a second chamber 6 by the partition plate 9, so that the two form relatively independent spaces. Moreover, the volume of the first chamber 5 and the second chamber 6 can be adjusted by adjusting the position of the partition plate 9 along the shell 1 according to the usage requirements and actual design requirements. The interference fit helps to prevent the e-liquid in the first chamber 5 from flowing into the second chamber 6 along the through hole 10.

[0040] Meanwhile, a sealing element 11 is provided at one end of the oil injection needle tube 8 near the end face of the housing 1. The sealing element 11 can be a sealing plug. In this embodiment, in order to facilitate the sealing of the oil injection needle tube 8 after injecting e-liquid into the first chamber 5 through the oil injection needle tube 8, the sealing element 11 is a cap made of silicone material. Taking advantage of the soft and easily deformable characteristics of silicone material, the oil injection needle tube 8 can be sealed through the sealing element 11. After the oil is injected into the first chamber 5 through the oil injection needle tube 8, the end of the oil injection needle tube 8 is sealed with the sealing element 11 to prevent e-liquid from leaking out of the oil injection needle tube 8.

[0041] Reference Figures 2-5The partition plate 9 is provided with a vent hole 12, which is formed through the thickness direction of the partition plate 9. The vent hole 12 connects the first chamber 5 and the second chamber 6, thereby balancing the air pressure inside the first chamber 5 and the second chamber 6, improving the smoothness of the e-liquid flowing from the first chamber 5 to the atomizing part 3. At the same time, because the air pressure inside the first chamber 5 and the second chamber 6 is in a balanced state, the presence of air bubbles in the e-liquid is effectively reduced, which to some extent solves the probability of the atomizing part 3 dry burning or uneven atomization caused by air bubbles mixed in the e-liquid.

[0042] The ventilation hole 12 is equipped with a one-way valve 15. The one-way valve 15 has the characteristic of opening in one direction, allowing air to enter the first chamber 5 in one direction, but restricting the e-liquid or atomized e-liquid from flowing back to the second chamber 6. It also effectively reduces the probability of foreign objects in the second chamber 6 entering the first chamber 5.

[0043] Reference Figures 3-5 A sealing assembly 13 is provided between the first chamber 5 and the partition plate 9. The sealing assembly 13 is used to restrict the flow of e-liquid in the first chamber 5 to the second chamber 6.

[0044] Specifically, a first step 14 is provided on the inner wall of the housing 1 near the first chamber 5. When the sealing component 13 is located in the first chamber 5, the sealing component 13 abuts against the first step 14. The first step 14 and the housing 1 are integrally formed by injection molding. The first step 14 provides an installation positioning reference for the sealing component 13, so that it can be accurately installed in the designated position of the housing 1 during the assembly process. Through the cooperation of the first step 14 and the partition plate 9, the sealing component 13 is restricted between the first step 14 and the partition plate 9, without the need for other mechanical structures to fix the sealing component 13, which is simple to operate.

[0045] It should also be noted that during the assembly process, the sealing component 13 should first be placed into the housing 1 along the second chamber 6 until the sealing component 13 abuts against the first step 14, and then the partition plate 9 should be installed into the housing 1.

[0046] Furthermore, the sealing assembly 13 includes a support plate 131 and a sealing silicone 132. The support plate 131 is made of metal material and the surface of the metal plate is nickel-plated, which helps to improve the corrosion resistance of the support plate 131 and reduce the probability of the e-liquid damaging the support plate 131.

[0047] Meanwhile, during the assembly process, the support plate 131 is first placed on the first step 14, and then the sealing silicone 132 is placed on the surface of the support plate 131 facing away from the first chamber 5. Then, the partition plate 9 is placed inside the housing 1 along the second chamber 6 until the partition plate 9 and the sealing silicone 132 come into contact. When the partition plate 9 and the sealing silicone 132 come into contact and a force is continuously applied to the partition plate 9, the sealing silicone 132 will be deformed, thereby filling the gap between the sealing silicone 132 and the housing 1 to improve the sealing performance. This reduces the probability of e-liquid flowing from the first chamber 5 into the second chamber 6 to a certain extent. Finally, the oil injection needle tube 8 is inserted along the through hole 10 (the oil injection needle tube 8 passes through both the sealing silicone 132 and the support plate 131) to complete the overall assembly.

[0048] In addition, a bottom cover 16 is provided at one end of the housing 1 near the second chamber 6. After the above operations are completed, the bottom cover 16 is used to seal the second chamber 6, so that the battery 4 can be stably fixed in the second chamber 6.

[0049] The implementation principle of the bottom-filled disposable electronic atomizer in this application embodiment is as follows: Through the first chamber 5, the second chamber 6 and the oil injection needle 8 extending from the bottom of the housing 1, an innovative structure for direct oil injection from the bottom of the housing 1 is achieved. Compared with the method of using a separate cartridge, this application does not require disassembling the housing 1 and can inject oil into the first chamber 5 through the oil injection needle 8, saving materials and production steps, and meeting the cost reduction requirements of disposable products.

[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
