Description

Technical Field

[0001] This utility model relates to the field of electronic atomizer technology, and in particular to an electronic atomizer that can prevent the atomizer core from burning out. Background Technology

[0002] An electronic atomizer is a device that uses electronic heating to convert a liquid (often called "e-liquid" or "vaporizer") into an inhalable aerosol. It is widely used in electronic cigarettes (electronic nicotine delivery systems), medical nebulizers, and some devices used for aromatherapy or recreational purposes.

[0003] Patent publication number CN222217230U discloses an electronic atomizer, including a shell, a mounting bracket, an atomizing component, and a power supply device. The mounting bracket is disposed within a receiving cavity, the atomizing component is disposed within the receiving cavity, and the power supply device is detachably mounted on the side of the mounting bracket away from the atomizing component. The power supply device provides electrical energy to the atomizing component and includes a battery compartment. The end of the battery compartment away from the mounting bracket includes a second snap-fit ​​portion, which engages with a first snap-fit ​​portion to mount the power supply device within the receiving cavity. While the power supply device in the aforementioned patent allows for quick disassembly and installation, improving the user experience, and facilitates the replacement and recycling of power supply devices in electronic atomizers, reducing environmental pollution, this patent lacks a dry-burn protection mechanism for the atomizing coil. Even when the e-liquid in the reservoir is insufficient or depleted, the atomizing component may still be heated, leading to dry-burning. This not only easily damages the atomizing coil but may also produce harmful substances, affecting user safety.

[0004] Therefore, there is a need for an electronic atomizer that can prevent the atomizer coil from burning out. Utility Model Content

[0005] In order to overcome the shortcomings of existing patents that do not have a dry-burn protection mechanism for the atomizer core, the atomizer component may still be heated when the e-liquid in the reservoir is insufficient or depleted, leading to dry burning. This not only easily damages the atomizer core but may also produce harmful substances, affecting the safety of the user. This utility model provides an electronic atomizer that can prevent the atomizer core from dry burning.

[0006] The technical solution of this utility model is as follows: an electronic atomizer that prevents the atomizer core from dry burning, comprising a shell, a battery, a control module, a charging interface, a cartridge, a mounting base, a ceramic atomizer, contact plates, electrode plates, an oil reservoir, an exhaust pipe, and a sponge pad.

The charging interface is located at the top of the shell. A cartridge is plugged into the upper part of the shell, and a mounting base is installed at the bottom of the cartridge. The ceramic atomizer is mounted on the mounting base, with two contact plates at the bottom of the ceramic atomizer. Two electrode plates are located at the top of the battery, and the electrode plates are in contact with the contact plates. The cartridge contains an oil reservoir with two outlet holes at the bottom, which are connected to a ceramic atomizer. An exhaust pipe connects to the inside of the reservoir, and a sponge pad is installed inside the outlet holes. It also includes a warning light, float plate, start switch, squeeze block, elastic element, and squeeze rod. A warning light is located on the front of the outer shell. The float plate slides inside the reservoir, and two mounting slots are located inside. The start switch is installed in each slot and is electrically connected to the warning light and control module. A squeeze block slides on the upper part of the mounting slot, and an elastic element connects the squeeze block to the reservoir. Two squeeze rods are fixedly connected to the bottom of the float plate.

[0007] As a preferred technical solution of this utility model, it also includes elastic buckles, with buckle holes on both the front and rear sides of the outer shell, and elastic buckles fixedly connected to both the front and rear sides of the tobacco cartridge, with the elastic buckles snapping into the buckle holes.

Detailed Implementation

[0024] 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.

[0025] Example 1: An electronic atomizer that prevents the atomizer coil from dry burning. Please refer to [link / reference]. Figures 1-8The device includes a casing 1, a battery 3, a control module 4, a charging interface 5, a cartridge 6, a mounting base 7, a ceramic atomizer 8, contact plates 9, electrode plates 10, an oil reservoir 11, an exhaust pipe 12, and a sponge pad 20. The casing 1 has an air inlet 2 on its right side. The battery 3 is housed inside the casing 1. The control module 4 is located at the bottom of the battery 3. The charging interface 5 is located at the top of the casing 1. The cartridge 6 is pluggable onto the upper part of the casing 1. A mounting base 7 is installed at the bottom of the cartridge 6, and a ceramic atomizer is mounted on the mounting base 7. The atomizer 8 has two contact plates 9 at its bottom, and the battery 3 has two electrode plates 10 at its top, which contact the contact plates 9. The cartridge 6 has an e-liquid storage chamber 11 inside, with two e-liquid outlet holes 1101 at its bottom, which are connected to the atomizer 8. An exhaust pipe 12 is connected inside the e-liquid storage chamber 11, and a sponge pad 20 is placed inside the e-liquid outlet holes 1101 to prevent e-liquid leakage. It also includes a warning light 101 and a float. The system includes a plate 13, a start switch 15, a compression block 16, an elastic element 17, and a compression rod 18. A warning light 101 is installed on the front side of the outer casing 1. A float 13 is slidably installed inside the oil storage tank 11. Two mounting slots 14 are provided inside the oil storage tank 11, and a start switch 15 is installed inside each slot. The start switch 15 is electrically connected to the warning light 101 and the control module 4. A compression block 16 is slidably installed on the upper part of the mounting slot 14, and an elastic element 17 connects the compression block 16 to the oil storage tank 11. The float 1... Two compression rods 18 are fixedly connected to the bottom of the 3-sealed plate 13. Two sealing plugs 19 are fixedly connected to the bottom of the floating plate 13. The sealing plugs 19 can block the oil outlet 1101. When the e-liquid is very low, the oil outlet 1101 can be partially blocked to slow down the loss of residual e-liquid and further prevent dry burning. A sleeve 25 is inserted inside the e-liquid cartridge 6. The sleeve 25 is connected to the exhaust pipe 12. The sleeve 25 is replaceable. If it is damaged, there is no need to discard the entire e-liquid cartridge 6. Several anti-slip grooves 26 are opened on the outer side of the outer shell 1 to improve the grip comfort and anti-slip performance.

[0026] During normal use, the ceramic atomizer 8 contacts the two electrode plates 10 on the top of the battery 3 via two contact plates 9 at the bottom, achieving electrical conduction. The control module 4 controls the battery 3 to supply power to the ceramic atomizer 8. At the same time, the e-liquid in the tank 11 continuously permeates into the ceramic atomizer 8 through the outlet 1101 to replenish it. The ceramic atomizer 8 heats up and atomizes the e-liquid, allowing the user to inhale the generated vapor. When the e-liquid in the tank 11 is sufficient, the float 13 floats above the liquid surface under buoyancy, and the two compression rods 18 at its bottom are also in a higher position, not in contact with the compression block 16 below. At this time, the start switch 15 installed in the two mounting slots 14 on the inner wall of the tank 11 is in the off state, and the warning light 101 is not lit. When the e-liquid is exhausted and the liquid level drops to a low level, the float 13 descends accordingly, and the compression rods 18 move downwards. When the squeezing block 16 is pressed, it moves downward against the resistance of the elastic element 17, triggering the start switch 15. After the start switch 15 is turned on, the warning light 101 lights up (e.g., flashing red or constantly lit), giving the user a clear warning that the e-liquid is about to run out, prompting them to replenish the e-liquid or replace the cartridge 6 in time. At the same time, the control module 4 can automatically cut off or limit the power supply to the ceramic atomizer 8 to prevent it from continuing to heat without enough e-liquid, thereby effectively avoiding dry burning and protecting the atomizer core and the user's safety. When the user replenishes the e-liquid or replaces the cartridge 6, the liquid level rises, the float plate 13 floats up, the squeezing rod 18 is released from the pressure on the squeezing block 16, and the squeezing block 16 moves upward and resets under the reset action of the elastic element 17. The start switch 15 is then turned off, the warning light 101 goes out, and the device returns to normal standby status.

[0027] Example 2: Based on Example 1, please refer to... Figure 2 , Figure 4 and Figure 8 It also includes elastic buckles 22, and the outer shell 1 has buckle holes 21 on both the front and back sides. The e-cigarette cartridge 6 is fixedly connected to the elastic buckles 22 on both the front and back sides, and the elastic buckles 22 are inserted into the buckle holes 21.

[0028] During the process of inserting the cartridge 6 into the outer shell 1, the elastic buckles 22 on both sides of the cartridge 6 first come into contact with the side wall of the outer shell 1 and are compressed due to elastic deformation. As the cartridge 6 continues to be inserted, when it is installed in place, the elastic buckles 22 are exactly aligned with the locking holes 21 on the outer shell 1. Under the action of elastic restoring force, they rebound and lock into the locking holes 21, thereby achieving a reliable lock between the cartridge 6 and the outer shell 1 and ensuring a stable connection.

[0029] Please see Figure 1 and Figure 8 It also includes an elastic connecting rope 23 and a sealing cap 24. The left side of the cartridge 6 is connected to the elastic connecting rope 23, and the upper part of the cartridge 6 is covered with the sealing cap 24. The other end of the elastic connecting rope 23 is connected to the sealing cap 24.

[0030] When the atomizer is not in use, cover it with the sealing cap 24 to block the upper part of the cartridge 6, thereby sealing the inlet of the exhaust pipe 12 and preventing dust and other foreign objects from entering.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
