Description

TECHNICAL FIELD

[0001] The present application relates to the field of electronic cigarettes, and particularly to a cartridge assembly with new-old detection function for automatic oil injection electronic cigarettes. BACKGROUND

[0002] In the existing automatic oil injection electronic cigarette technology, the cartridge assembly usually replenishes the oil amount based on the number of working times, the inhalation duration or the preset amount of oil. This oil supply method can effectively maintain the working state of the atomizer in normal use, but the conventional automatic oil injection system cannot meet the special needs of the new cartridge when the cartridge is replaced for the first time. Specifically, when the user replaces the new cartridge, the atomizer and the cotton core have not been fully wetted by the oil. Especially at the initial use, the cotton core needs to inhale enough oil to effectively supply the atomizer for normal work. Due to the particularity of this process, the first oil injection amount and time are much higher than those in the normal use. If the system cannot recognize the initial state of the cartridge and work according to the normal state at this time, that is, the oil injection is carried out according to the normal oil injection amount and time, a series of problems will be caused. First, the atomizer cannot work normally without enough oil, resulting in no smoke; second, the atomizer is prone to damage due to dry burning in the first few times, which may directly cause the atomizer to fail and affect the normal use of the device. Even if the atomizer is not directly damaged, its service life may be greatly shortened due to long-term dry burning, and it may not work normally within the designed period.

[0003] The root cause of these problems lies in the lack of accurate detection and recognition of the new-old state of the cartridge in the existing technology, which cannot intelligently adjust the initial oil injection amount. The existing system usually relies on fixed oil injection amount and time control, which is not suitable for the initial use of the new cartridge. Due to the lack of differentiated treatment for new and old cartridges, the system cannot provide the appropriate amount of oil when the cartridge is replaced, causing the initial atomizer to dry burn or the oil amount to be too much, thereby affecting the performance and service life of the electronic cigarette.

[0004] At present, although the additional oil supply control of the new cartridge can be realized by manual control, this method is obviously not convenient enough and increases the operation complexity of the user. Manual control mainly includes two ways: the first way is that after the cartridge is installed, the system will supply oil according to the demand of the new cartridge regardless of its new or old state, to ensure sufficient oil at the initial stage. Although this method can meet the oil supply demand of the new cartridge, when the user installs the old cartridge, the system will over-supply oil, causing oil overflow and affecting the use experience. The second way is to require the user to manually select whether the cartridge is new or not, and control the oil supply degree accordingly. Although this method can avoid over-supply of oil, it depends on the user's judgment of the new or old state of the cartridge, which is easy to cause oil overflow or insufficient oil supply due to incorrect judgment. At the same time, this method also fails to realize real intelligent automatic identification, increasing the complexity in use and reducing the convenience of the user and the intelligent degree of the electronic cigarette. Especially, this method is usually only applicable to high-end electronic cigarette products and cannot be popularized to a wider user group.

[0005] Although the judgment based on the number of uses or the starting state can be realized by adding a communication structure and a communication chip, so as to automatically adjust the oil amount when the cartridge is replaced, in order to accurately control the oil supply demand of the new or old cartridge. However, this method usually requires additional hardware support, including the communication structure and chip inside the cartridge, which not only increases the design complexity of the product, but also greatly increases the production cost of the cartridge. In the electronic cigarette industry, especially for disposable cartridge products, cost control is a key factor. The introduction of communication chips and related hardware will not only greatly increase the cost of the cartridge, but also may affect the market competitiveness of disposable cartridges. Therefore, although the chip communication scheme can effectively solve the identification problem of new or old cartridges, its high cost does not meet the market positioning and cost control requirements of disposable cartridges.

[0006] In order to overcome the shortcomings of the existing manual control method and avoid the high-cost chip communication scheme, a new technical scheme is needed in the industry. Invention content

[0007] The purpose of the present application is to at least overcome one of the shortcomings of the prior art, and to provide a cartridge assembly with new and old detection function for automatic oil injection electronic cigarette, which can automatically judge the new or old state of the cartridge through a low-cost identification mechanism, and accurately adjust the oil injection amount according to the identification result, to ensure that the cotton core can fully absorb oil, thereby avoiding the dry burning problem of the atomizing core and ensuring the normal work of the equipment.

[0008] To achieve the above object, the application discloses a new and old detection function automatic oil injection electronic cigarette cartridge assembly, which comprises a cartridge body with a working channel, an atomizing core arranged in the working channel, and a cotton core arranged in the cartridge body and in contact with the atomizing core.

[0009] As an optional technical solution, the one-time fuse wire is a short-circuit copper foil.

[0010] Compared with the prior art, the application has at least one of the following beneficial technical effects:

[0011] 1. Accurate identification of new and old cartridge status: Through the low-cost fuse wire identification mechanism, the new and old status can be accurately judged when the cartridge is used for the first time, ensuring that the system automatically adjusts the oil injection amount according to the actual situation of the cartridge. This automated process greatly simplifies user operation and avoids the complexity of manual control.

[0012] 2. Avoiding dry burning of the atomizing core and prolonging the service life: After identifying that the cartridge is a new cartridge, the system can provide additional oil supply to ensure that the cotton core is fully wetted and prevent the atomizing core from dry burning due to lack of oil. This not only improves the efficiency of the device, but also greatly prolongs the service life of the atomizing core.

[0013] 3. Low-cost intelligent control: The use of one-time fuse wire design avoids expensive chip communication solutions, thereby achieving intelligent identification of new and old cartridges while maintaining low production costs. This makes the technology not only suitable for high-end products, but also effectively applicable to the cost-sensitive disposable cartridge market, with wider market adaptability.

[0014] The above listed beneficial effects are not exhaustive of all advantages. Other potential beneficial effects and detailed technical implementation methods will be further disclosed in the embodiments or other description parts of the application. BRIEF DESCRIPTION OF DRAWINGS

[0022] Referring to the accompanying drawings, Figure 1 and 2 , the present embodiment describes in detail the composition and connection relationship of the automatic oil injection electronic cigarette cartridge assembly with new and old detection function to be used in the initial stage of work to detect and judge the new and old cartridge, and to adjust the oil supply according to the judgment result.

[0023] In terms of structural composition, the cartridge assembly includes a cartridge body 1, a working channel 2, an atomizing core 3, a cotton core 4, a positive terminal 5, a negative terminal 6, and a one-time fuse wire 7.

[0024] Specifically, the cartridge body 1 is made of heat-resistant plastic or similar material, which has good sealing performance and strength, and can effectively withstand the high temperature and pressure generated during atomization. The cartridge body 1 is internally provided with a working channel 2, which is used to send the smoke generated by the atomization core 3 out.

[0025] The atomization core 3 is one of the core components of the cartridge assembly, and its main function is to convert oil into smoke. The atomization core 3 is composed of a resistance wire (such as tungsten wire or stainless steel wire) and a ceramic or metal base. When the electric current passes through the resistance wire, it heats the atomization core, which in turn atomizes the oil into smoke to meet the needs of use.

[0026] As a conventional design, the atomization core 3 is connected to the working channel 2 in the cartridge body 1, ensuring that the generated smoke can smoothly flow out and be sent out through the working channel 2 for the user to inhale.

[0027] As a conventional design, the cotton core 4 is located around the atomization core 3 and is responsible for absorbing and storing oil. The material of the cotton core 4 is usually organic cotton or high-absorption fiber, which has strong oil absorption and can guide the oil from the cartridge to the atomization core 3. The cotton core 4 ensures that the oil is evenly distributed to the heating area of the atomization core 3, so that the atomization core can work stably and avoid dry burning.

[0028] In order to determine the new and old state of the cartridge and adjust the supply of oil, the present embodiment is connected between the positive terminal 5 and the negative terminal 6 by a one-time fuse wire 7. The one-time fuse wire 7 is usually made of low-resistance materials such as copper foil, which provides a low-resistance path during initial operation to ensure that the current can flow smoothly and in turn heat the atomization core 3. The main function of this wire 7 is to provide initial heating for the atomization core 3 through the flow of current, thereby helping to determine the new and old state of the cartridge.

[0029] Specifically, when the cartridge is used for the first time, the external MCU (Micro Control Unit) will perform a one-time detection at the initial stage of work to determine whether the cartridge is a new cartridge or an old cartridge. The detection process is completed by monitoring the change of resistance value. When the MCU detects that the resistance value between the positive terminal 5 and the negative terminal 6 is low in the initial stage of work, the MCU determines that the cartridge is a new cartridge. At this time, the MCU will prolong the oil supply time to ensure that more oil is supplied, so that the cotton core 4 can fully absorb the oil, and the atomization core 3 is prevented from being dry burned due to insufficient oil.

[0030] More specifically, the disposable fuse wire 7 conducts current at the initial stage of work. When the current passes through, the copper foil material has a low resistance, providing a low resistance path. When the normal work starts, the wire 7 will be fused due to overheating after a certain period of time, and the resistance value between the terminals will rise sharply. The MCU can determine whether the cartridge has been used by monitoring this resistance change. If a low resistance state is detected, it is determined that it is a new cartridge, and the oil supply time is extended.

[0031] The innovation of the embodiment is that by the low resistance characteristic of the disposable fuse wire 7 and the detection of resistance change by the MCU, the new and old state of the cartridge can be intelligently determined at the initial stage of work, and the oil supply amount is adjusted accordingly. This way not only saves costs, but also avoids the mistakes and troubles brought by traditional manual control. Compared with the high-cost communication chip solution, the embodiment has a significant cost advantage and can realize efficient intelligent identification and oil supply control.

[0032] It can be understood that the embodiment introduces a disposable fuse wire 7 and a low resistance judgment mechanism to provide a low-cost and intelligent oil supply adjustment method. This method can intelligently identify a new cartridge when the cartridge is replaced and extend the initial oil supply time, avoid dry burning, improve the working stability of the atomizing core 3, and prolong its service life. At the same time, the components in the embodiment have reasonable structures and close cooperation, which can ensure the stability and reliability of the equipment during use, and optimize the user's experience.

[0033] Although the exemplary embodiments of the present disclosure have been described, those skilled in the art should understand that various changes and modifications can be made to the exemplary embodiments of the present disclosure without departing from the spirit and scope of the present disclosure in essence. Therefore, all changes and modifications are included in the protection scope of the present disclosure defined by the claims. The present disclosure is defined by the appended claims, and the equivalents of these claims are also included.
