An electronic atomizer with overheat protection structure

Abstract

This utility model relates to the field of electronic atomization equipment technology, and in particular to an electronic atomizer with an overheat protection structure. It includes an electronic atomizer body, with an e-liquid storage chamber installed in the lower part of the body. A feed pipe is connected to and communicates with the side of the e-liquid storage chamber. A passive overheat protection mechanism is formed by incorporating a temperature fuse in the circuit between the heating sleeve and the battery. When the heating sleeve experiences an abnormal temperature rise exceeding a preset safety threshold due to circuit failure, continuous heating, or temperature control malfunction, the thermistor inside the temperature fuse responds rapidly, melting or experiencing a surge in resistance, automatically cutting off the power supply. This fundamentally prevents safety hazards such as e-liquid carbonization, fire, and explosion, significantly improving the safety and reliability of the equipment. Furthermore, the atomization chamber adopts a detachable installation structure, allowing for individual replacement of the atomization module when the heating element is damaged, eliminating the need to scrap the entire main unit, reducing operating costs, and extending the main unit's lifespan.

Description

Technical Field

[0001] This utility model relates to the field of electronic atomization equipment technology, and in particular to an electronic atomizer with an overheat protection structure. Background Technology

[0002] An electronic atomizer is an electronic device that atomizes a liquid medium into fine aerosols through electrothermal processes. It is widely used in electronic cigarettes, medical nebulizers, and aromatherapy devices. Its basic working principle involves using battery power to drive a heating element, which instantly heats the liquid e-liquid containing nicotine, medication, or flavoring, causing it to vaporize or atomize and form a mist-like particle that the user can inhale.

[0003] Current electronic atomizers typically consist of an e-liquid storage chamber, an atomization assembly, a power module, and control circuitry. The atomization assembly contains an atomizing coil and a heating element. However, in actual use, electronic atomizers face numerous safety and reliability issues. Circuit malfunctions, continuous heating, or temperature control failures can cause the heating element's temperature to rise rapidly, exceeding its safe operating range. Excessive temperature can not only cause localized carbonization of the e-liquid, producing harmful decomposition products such as benzene and formaldehyde, affecting the user's health, but in more serious cases, it can ignite internal flammable materials, leading to overheating, fire, or even explosion, posing significant safety hazards. Furthermore, because the electronic atomizer and atomization assembly are integrated and fixed, if the heating element fails due to overheating, the user cannot replace the atomization assembly separately; they must replace the entire electronic atomizer, resulting in resource waste, increased operating costs, and is detrimental to environmental protection and sustainable use.

[0004] Therefore, there is an urgent need to provide an electronic atomizer with a detachable atomization module and an overheat protection structure. Utility Model Content

[0005] In order to overcome the shortcomings of existing electronic atomizers, such as uncontrolled heating temperature, significant safety hazards, and high maintenance costs and resource waste due to the non-replaceable atomizing components, this utility model provides an electronic atomizer with a detachable atomizing module and an overheat protection structure.

[0006] To address the aforementioned issues, this utility model employs the following technical solution: an electronic atomizer with an overheat protection structure, comprising an electronic atomizer body, an e-liquid storage chamber installed in the lower part of the electronic atomizer body, a feed pipe connected and communicating with the side of the e-liquid storage chamber, a one-way valve installed on the feed pipe, a threaded through hole provided on the lower side of the electronic atomizer body, an internally threaded cap threaded onto the threaded through hole, a connecting pipe connected to the top of the e-liquid storage chamber, a pump installed at one end of the connecting pipe near the e-liquid storage chamber, an atomizing chamber detachably installed in the upper part of the electronic atomizer body, the atomizing chamber communicating with the other end of the connecting pipe, an atomizing core disposed inside the atomizing chamber, a battery embedded in the side of the atomizing chamber, a heating sleeve covered outside the atomizing core, the heating sleeve electrically connected to the battery via a wire, and a thermal fuse connected between the heating sleeve and the battery via a wire.

[0007] Furthermore, the outer surface of the internal threaded cap is provided with anti-slip texture.

[0008] Furthermore, a first protective shell is provided on both sides of the lower part of the electronic atomizer body. A slide rod is slidably provided inside the first protective shell. A locking block is fixed to the top of the slide rod. A guide slope is provided on the locking block. A first elastic element is sleeved on the slide rod. The two ends of the first elastic element are respectively connected to the locking block and the electronic atomizer body. Mounting blocks are provided on both sides of the atomization chamber. A locking groove matching the locking block is provided at the bottom of the mounting block.

[0009] Furthermore, guide rods are fixedly connected to both sides of the upper part of the electronic atomizer body, and a sliding frame is slidably provided on the guide rods. The sliding frame has a U-shaped structure, and its lower end is fixedly connected to the bottom end of the sliding rods on both sides. A second elastic element is sleeved on the guide rod, and the two ends of the second elastic element are respectively connected to the sliding frame and the guide rod.

[0010] Furthermore, a second protective shell is provided on the top of the electronic atomizer body, and the second protective shell covers the sliding frame.

[0011] Furthermore, the mouthpiece of the electronic atomizer body is provided with a first magnetic ring, the mouthpiece of the electronic atomizer body is covered with a protective cover, and a second magnetic ring is provided at the bottom of the protective cover.

[0012] Compared with the prior art, this utility model has the following technical effects: 1. By setting a temperature fuse in the circuit of the heating jacket and the battery, a passive overheat protection mechanism is formed. When the temperature of the heating jacket rises abnormally and exceeds the preset safety threshold due to circuit failure, continuous heating or temperature control failure, the internal thermal material of the temperature fuse responds quickly, melts or increases in resistance, and automatically cuts off the power supply, fundamentally preventing safety hazards such as carbonization of e-liquid, fire, and explosion, and significantly improving the safety and reliability of the equipment. In addition, the atomization chamber adopts a detachable installation structure, which allows the atomization module to be replaced separately when the heating element is damaged, without the need to scrap the entire main unit, reducing the cost of use and extending the service life of the main unit.

[0013] 2. By setting up a quick-release locking mechanism consisting of a locking block, a sliding rod, an elastic element, a mounting block, and a locking groove, and in conjunction with the linkage reset structure of the sliding frame and the guide rod, the atomization chamber can be automatically locked when pushed in and easily disassembled by pressing, thus balancing ease of operation and structural stability.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1: Please refer to Figures 1-3 An electronic atomizer with an overheat protection structure includes an electronic atomizer body 1. An e-liquid storage chamber 2 is installed in the lower part of the electronic atomizer body 1. A feed pipe 3 is connected to and communicates with the right side of the e-liquid storage chamber 2. A one-way valve 4 is installed on the feed pipe 3. A threaded through hole is provided on the lower side of the electronic atomizer body 1. An internally threaded cap 5 is threaded onto the threaded through hole to seal the e-liquid filling port, preventing leakage and the entry of external contaminants. Furthermore, the outer surface of the internally threaded cap 5 has anti-slip textures. These textures are raised structures evenly distributed along the circumference of the cap, significantly increasing the friction between the user's fingers and the internally threaded cap 5, making it easy to unscrew or tighten the cap during e-liquid filling or maintenance. The e-liquid storage chamber 2 is connected to a connecting pipe 6 at its top. A pump 7 is installed at one end of the connecting pipe 6 near the e-liquid storage chamber 2. An atomizing chamber 8 is detachably installed in the upper part of the electronic atomizer body 1. The atomizing chamber 8 is connected to the other end of the connecting pipe 6. The atomizing chamber 8 can be inserted or removed horizontally for quick replacement. An atomizing core 801 for absorbing e-liquid is installed inside the atomizing chamber 8. A battery 802 is embedded on the right side of the atomizing chamber 8. A heating sleeve 9 is fitted outside the atomizing core 801. The heating sleeve 9 is electrically connected to the battery 802 through a wire. A thermal fuse 10 is connected between the heating sleeve 9 and the battery 802 through a wire.

[0023] When using this device, first unscrew the inner threaded cap 5 at the bottom to expose the threaded through hole, then inject e-liquid into the feed pipe 3. The e-liquid enters the e-liquid storage chamber 2 through the one-way valve 4, which prevents backflow. Then, start the extraction pump 7 to transport the e-liquid from the storage chamber to the upper atomizing chamber 8 through the connecting pipe 6, immersing the atomizing core 801 within. When the user starts the device, the battery 802 supplies power to the heating jacket 9, which heats the e-liquid-immersed atomizing core 801, causing it to atomize and produce inhalable vapor. During the heating process, if a circuit malfunction occurs and the heating is interrupted... If the temperature of the heating jacket 9 rises abnormally and exceeds the preset safety threshold due to heat or temperature control failure, the heat-sensitive material inside the temperature fuse 10 will expand due to heat, causing its resistance to increase sharply. This will eventually trigger the circuit to automatically disconnect, cutting off the power supply to the heating jacket 9, thus achieving overheat protection and preventing the equipment from catching fire or being damaged. The temperature fuse 10 is a one-time protection component and needs to be replaced after it is triggered and disconnected. Since the atomizing chamber 8 is a detachable structure, it is convenient for users to replace the atomizing components. Alternatively, the temperature fuse 10 can be replaced separately after the atomizing chamber 8 is removed, improving the safety and maintenance convenience of the equipment.

[0024] Example 2: Based on Example 1, please refer to... Figure 4 The electronic atomizer body 1 has a first protective shell 11 on both the front and rear sides of its lower part. A slide rod 12 is slidably arranged inside the first protective shell 11. A locking block 13 is fixed to the top of the slide rod 12. A guide slope is provided on the locking block 13. A first elastic element 14 is sleeved on the slide rod 12. The two ends of the first elastic element 14 are respectively connected to the locking block 13 and the electronic atomizer body 1, and are used to provide an upward reset elastic force for the locking block 13. Mounting blocks 15 are provided on both sides of the atomization chamber 8. The bottom of the mounting block 15 has a slot that matches the locking block 13.

[0025] Please see Figure 5 The electronic atomizer body 1 has guide rods 16 fixedly connected to both the front and rear sides of its upper part. The guide rods 16 are slidably mounted on a sliding frame 17. The sliding frame 17 has a U-shaped structure, and its lower end is fixedly connected to the bottom end of the sliding rods 12 on both sides. A second elastic element 18 is sleeved on the guide rod 16. The two ends of the second elastic element 18 are respectively connected to the sliding frame 17 and the guide rod 16, which is used to provide an upward reset force for the sliding frame 17. A second protective shell 19 is provided on the top of the electronic atomizer body 1. The second protective shell 19 covers the sliding frame 17 and plays a role in physical protection and preventing dust and foreign objects from entering, so as to avoid external dust, liquid or mechanical collisions affecting the normal movement of the sliding frame 17.

[0026] When installing the atomizing chamber 8, the user inserts the atomizing chamber 8 horizontally into the electronic atomizer body 1. As the mounting blocks 15 on both sides of the atomizing chamber 8 gradually approach the first protective shell 11, the left side of the mounting block 15 first contacts the guide slope on the locking block 13 and applies oblique pressure. This pressure forces the locking block 13 to overcome the elastic force of the first elastic element 14, causing the slide rod 12 to move downward along the inside of the first protective shell 11. This allows the locking block 13 to make room for the installation, allowing the mounting block 15 to slide smoothly into the inside of the first protective shell 11. When the atomizing chamber 8 is fully inserted, the slot at the bottom of the mounting block 15 aligns with the locking block 13. At this time, under the restoring force of the first elastic element 14, the locking block 13 automatically springs upward and embeds into the slot, forming a mechanical limit, thus achieving... The atomizing chamber 8 is reliably locked to prevent it from accidentally loosening or slipping out during use due to vibration or airflow impact. When it is necessary to disassemble the atomizing chamber 8, the user presses down on the sliding bracket 17 located on the upper part of the electronic atomizer body 1. The sliding bracket 17 moves downward along the guide rod 16, compressing the second elastic element 18, and simultaneously driving the sliding rods 12 and the locking block 13 on both sides to move downward, so that the locking block 13 is completely disengaged from the slot of the mounting block 15, releasing the locked state. At this time, the user can easily pull out the atomizing chamber 8 in the horizontal direction to complete the replacement or maintenance operation. After releasing the sliding bracket 17, under the elastic force of the second elastic element 18, the sliding bracket 17 automatically resets upward, and at the same time drives the sliding rods 12 and the locking block 13 to return to the initial locked position, ready for the next installation operation.

[0027] Please see Figure 6 The mouthpiece of the electronic atomizer body 1 is provided with a first magnetic ring 20, and a protective cover 21 is fitted over the mouthpiece of the electronic atomizer body 1. A second magnetic ring 22 is provided at the bottom of the protective cover 21. The two magnetic rings are opposite in polarity and form a magnetic connection, which can realize the quick installation and stable fixation of the protective cover 21. In addition, when the device is idle or carried, the protective cover 21 can effectively prevent dust, bacteria and liquids from entering the mouthpiece, ensuring hygiene and safety.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
