Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic cigarette technology, and in particular to an electronic atomizer that prevents dry burning. Background Technology
[0002] Electronic atomizers, as an innovative device designed to replace traditional tobacco products, have been widely used and developed globally in recent years. Their main working principle is to heat a liquid containing nicotine, flavorings and other ingredients to generate an aerosol that can be inhaled, providing users with a simulated smoking experience.
[0003] However, with increased usage frequency and technological advancements, some problems with traditional e-cigarettes have gradually emerged, particularly regarding device safety and user experience. One particularly prominent issue is the lack of an effective anti-dry-burn mechanism in traditional e-cigarettes. When the device continues to operate without sufficient e-liquid, a so-called "dry-burn" phenomenon occurs. In this situation, because the atomizer coil does not receive a sufficient supply of e-liquid for evaporation but is still continuously heated, it not only leads to unnecessary damage to the atomizer coil and heating element but may also promote the release of harmful substances, posing a potential threat to the user's health. Furthermore, "dry-burn" significantly affects the user's sensory experience, producing unpleasant tastes and odors, greatly reducing the user experience.
[0004] Therefore, there is an urgent need to develop an electronic atomizer that prevents dry burning. Utility Model Content
[0005] In order to overcome the shortcomings of traditional electronic atomizers that lack anti-dry-burning function and are prone to dry burning when e-liquid is insufficient, which can damage the device and pose potential health risks, this utility model provides an electronic atomizer that prevents dry burning.
[0006] To address the aforementioned issues, this utility model employs the following technical solution: an anti-dry-burning electronic atomizer includes a housing, a fume chamber snapped onto the top of the housing, a porous ceramic atomizing core disposed inside the fume chamber, the bottom of the porous ceramic atomizing core having a built-in heat-conducting contact structure, a filter head snapped onto the top of the fume chamber, a mouthpiece snapped onto the outside of the fume chamber, a heating element installed inside the housing, the heating contact of the heating element extending upward to the bottom of the fume chamber and directly contacting the bottom of the porous ceramic atomizing core, a button on the outside of the housing electrically connected to the heating element, a storage battery module installed inside the housing, the storage battery module located below the heating element and connected to it by a wire, a liquid level monitor installed on the inner side wall of the housing with its probe extending into the fume chamber at a specific height, a status indicator light embedded in the lower part of the housing, and a microcontroller installed on the inner side wall of the housing, the liquid level monitor, the microcontroller, and the status indicator light being electrically connected.
[0007] In one embodiment, telescopic rods are slidably provided at both ends of the U-shaped support frame. The telescopic rods and the U-shaped support frame together form a structure that supports the electronic atomizer. A locking rod is provided at the top of the telescopic rod. The outer shell has a locking groove structure that matches the locking rod on both sides. The U-shaped support frame has multiple sets of locking holes inside. Locking balls are provided on both sides of the lower part of the telescopic rod. A spring connects the locking balls to the telescopic rod.
[0008] In one embodiment, a retaining ring is fitted on the outside of the fume chamber, and an elastic ring is fitted on the outside of the retaining ring, with an anti-loss rope connected to the elastic ring.
[0009] In one embodiment, the anti-loss rope is equipped with a rubber cover.
[0010] In one embodiment, the bottom of the U-shaped support frame is provided with anti-slip texture.
[0011] In one embodiment, a rubber grip plate is provided on the outside of the fume chamber.
[0012] Compared with the prior art, the present invention has the following technical effects: 1. The product is equipped with a liquid level sensor, which can monitor the amount of e-liquid in the fume chamber in real time. Once the amount of e-liquid is detected to be too low and close to dry burning, the liquid level sensor sends a signal to the micro controller to control the status indicator light to flash as a reminder, so as to avoid dry burning and thus ensure the safety and comfort of use.
[0013] 2. By adopting a combination design of U-shaped support frame and telescopic rod, the electronic atomizer can be placed upright during storage, reducing the risk of e-liquid leakage. In addition, the use of retaining rings and elastic rings combined with anti-loss ropes facilitates carrying. These measures increase the product's ease of operation and reliability, meeting the diverse needs of users. Attached Figure Description

Detailed Implementation
[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.
[0023] Example 1: Please refer to Figures 1-4An anti-dry-burning electronic atomizer includes a housing 1, with an oil vapor chamber 2 for storing e-liquid snapped onto the top of the housing 1. The oil vapor chamber 2 contains a porous ceramic atomizing core 201, the bottom of which has a built-in heat-conducting contact structure. A rubber grip 21, made of a soft material with a high coefficient of friction, is provided on the outside of the oil vapor chamber 2, offering a comfortable, non-slip grip. This allows the user to hold the electronic atomizer more firmly during use, improving ease of use and comfort. A filter head 3 is snapped onto the top of the oil vapor chamber 2, filtering large particles in the vapor. Its detachable design facilitates replacement and refilling of the oil vapor chamber 2. A mouthpiece 4 is snapped onto the outside of the oil vapor chamber 2. A heating element 5 is installed inside the housing 1, with its heating contacts extending upwards. The bottom of the fume chamber 2 is in direct contact with the bottom of the porous ceramic atomizing core 201. A button 6 is provided on the lower side of the outer shell 1. The button 6 is electrically connected to the heating element 5 and is used to turn the heating element 5 on and off. A storage battery module 7 is installed inside the shell 1. The storage battery module 7 is located below the heating element 5 and the two are connected by wires to provide power to the heating element 5. A liquid level monitor 8 is installed on the inner side wall of the shell 1. Its probe extends into the fume chamber 2 to a specific height to detect the amount of e-liquid. A status indicator light 10 is embedded in the lower part of the shell 1. The status indicator light 10 integrates red and green dual-color LED indicators to display the status of the electronic atomizer. A microcontroller 9 is installed on the inner side wall of the shell 1. The liquid level monitor 8, the microcontroller 9 and the status indicator light 10 are electrically connected. The microcontroller 9 can control the status changes of the indicator light according to the information provided by the liquid level monitor 8.
[0024] When the user uses this electronic atomizer, pressing button 6 activates the heating element 5, which rapidly heats the porous ceramic atomizing core 201, causing the e-liquid to evaporate into aerosol. This aerosol is then filtered through the filter head 3 to remove large particles of harmful substances before entering the mouthpiece 4 for the user to inhale. As the user continues to use the device, when the amount of e-liquid in the vapor chamber 2 decreases to a certain level, i.e., when the e-liquid level drops to the position of the level monitor 8 probe, it indicates that the e-liquid level is too low and close to dry burning. At this time, the level monitor 8 sends a signal to the microcontroller 9. Upon receiving the signal, the microcontroller 9 controls the status indicator light 10 to flash red (the status indicator light 10 is a solid green light when the electronic atomizer is in normal use), reminding the user to add e-liquid in time. This effectively avoids the problem of dry burning of the porous ceramic atomizing core 201 and the heating element 5 due to insufficient e-liquid. When e-liquid needs to be added, simply remove the mouthpiece 4 and the filter head 3 to add e-liquid into the vapor chamber 2.
[0025] Example 2: Based on Example 1, please refer to... Figure 5 and Figure 6 The U-shaped support frame 11 has telescopic rods 12 slidably installed at both ends. The telescopic rods 12 and the U-shaped support frame 11 together form a structure to support the electronic atomizer. The bottom of the U-shaped support frame 11 has anti-slip texture 20. The anti-slip texture 20 increases the friction between the U-shaped support frame 11 and the surface it is placed on, preventing the U-shaped support frame 11 from moving or slipping on a smooth surface. The top of the telescopic rod 12 is provided with a locking rod 13, and the left and right sides of the outer shell 1 are provided with locking grooves that match the locking rod 13. The structure uses a locking rod 13 to engage with a slot on the outer shell 1, thus fixing the electronic atomizer to the telescopic rod 12. The U-shaped support frame 11 has two sets of locking holes inside, with four holes in each set, and the four locking holes are evenly arranged in the vertical and horizontal directions. The telescopic rod 12 has locking balls 15 on both the front and rear sides at the bottom. A spring 14 connects the locking balls 15 to the telescopic rod 12, and the spring 14 provides extension and retraction for the locking balls 15, allowing them to engage with the corresponding locking holes, thereby locking the position of the telescopic rod 12.
[0026] Please see Figure 7 The oil fume chamber 2 is fitted with a retaining ring 16 on the outside, and an elastic ring 17 is fitted on the outside of the retaining ring 16. An anti-loss rope 18 is connected to the elastic ring 17, and a rubber cover 19 is provided on the anti-loss rope 18. When the electronic atomizer is not in use, the rubber cover 19 is used to cover the mouthpiece 4 to protect the mouthpiece 4 from dust and other pollutants.
[0027] When storing the e-cigarette, it can be placed on the U-shaped support frame 11. First, pull the telescopic rod 12 upwards to adjust it to a suitable length to accommodate e-cigarettes of different sizes. During the movement of the telescopic rod 12, the locking ball 15 automatically engages with the corresponding locking hole through the action of the spring 14, locking the position of the telescopic rod 12. Then, fix the e-cigarette on the U-shaped support frame 11 by aligning the locking rod 13 with and inserting it into the locking slot structure on both sides of the outer shell 1, ensuring that the e-cigarette remains upright. When the atomizer is kept upright, due to gravity, the e-liquid naturally concentrates at the bottom, away from the airflow channels and potential leakage paths of the e-liquid, reducing the risk of accidental spillage or leakage. When the user needs to take the e-liquid out, the user removes the e-liquid from the U-shaped support 11 and inserts the retaining ring 16 into the outside of the e-liquid chamber 2. Then, the elastic ring 17 is put on the outside of the retaining ring 16 to complete the installation of the anti-loss rope 18. In this way, the user can hang the e-liquid around their neck, which is convenient to carry and not easy to lose.
