Description

Technical Field

[0001] The utility model relates to the field of electronic power, and in particular to a passive electronic cigarette and a power cord. Background Art

[0002] An electronic cigarette is a device that produces steam by heating the e-liquid. Traditional electronic cigarettes are usually powered by a built-in lithium battery with a voltage output of 3.7V. Existing electronic cigarettes use a pneumatic switch to control the battery output voltage and current to the heating wire, thereby realizing the atomization function of the e-liquid. However, this power supply method has many disadvantages: the high cost of lithium batteries, limited service life, poor environmental performance, and serious power consumption problems after long-term storage, resulting in poor user experience. For example, when the power supply mode of the lithium battery changes from strong to weak, the lithium battery will go to about 4.2 at the beginning of full charge. Since the load is unchanged, it will go to 3.5V in the later stage of practical use. At this time, the power will be weakened, and the output taste will change from the original taste.

[0003] In view of this, this application is filed. Utility Model Content

[0026] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0027] The utility model discloses a passive electronic cigarette and a power cord, aiming to solve the problem that the power supply voltage of the existing electronic cigarette gradually weakens with the increase of use time, thus affecting the atomization effect of the electronic cigarette and the user experience.

[0028] See also Figure 1 and Figure 2The first embodiment of the utility model provides a passive electronic cigarette, comprising: an electronic cigarette body, a power interface 7 configured on the electronic cigarette body, a pneumatic switch 6 and a heating wire 5;

[0029] The power interface 7 is electrically connected to the first electrode of the heating wire 5, the power interface 7 is used to be connected to an external power source through a power line, and the power interface 7 is electrically connected to the second electrode 10 through the pneumatic switch 6;

[0030] The external power supply is configured to supply power to the electronic cigarette body through an OTG function.

[0031] It should be noted that the inventors have found that the power supply performance of lithium batteries gradually weakens with the increase of usage time. In the early stage of full charge, the voltage of the lithium battery is about 4.2V, but due to the constant load, the voltage will drop to about 3.5V in the later stage of use. At this time, the power will be significantly weakened, causing the output taste to change from the initial taste. In addition, the material cost and production and storage cost of lithium batteries are high, and the cost of use for consumers also increases accordingly. Moreover, lithium batteries are not environmentally friendly. The batteries become waste after use, which will pollute the environment. The passive electronic cigarette provided in the first embodiment of the utility model has a simple physical structure and an electrical structure. All corresponding electronic circuits supporting power supply are transferred to a power line with a special structure as an accessory. This effectively solves the problems of existing electronic cigarettes having many consumables, great manufacturing difficulty, and high manufacturing cost due to the corresponding electronic circuits supporting power supply, and high battery cost and environmental pollution due to the special power supply battery installed inside. At the same time, it effectively solves the problem that the battery power supply voltage configured in the existing electronic cigarette gradually weakens with the increase of usage time, thereby affecting the atomization effect and user experience of the electronic cigarette. This effectively breaks the inertial thinking of those skilled in the art and provides a low-cost, green, and environmentally friendly technical route with extremely simplified physical and electrical structures for the research and development of electronic cigarettes.

[0032] In this embodiment, the power supply inside the electronic cigarette body is cancelled, and the electronic cigarette is powered entirely by an external power supply. Specifically, the power interface 7 is used to connect to an external power supply through a power cord. The passive electronic cigarette can be compatible with different types of external power supply devices, such as mobile phones, tablets, mobile power supplies, laptops, etc., which greatly improves the versatility and convenience of the device. Users do not need to worry about not being able to power the electronic cigarette due to interface mismatch. Regardless of the device used, the user can easily find a suitable power connection method. Further, in this embodiment, the pneumatic switch is configured to conduct the circuit when the user inhales, and conduct the heating wire circuit.

[0033] See also Figure 3The second embodiment of the utility model provides a power cord adapted to the passive electronic cigarette, including: a circuit body, a first interface 1 configured on the circuit body, a second interface 2, a voltage control circuit 3, a load protection circuit 8 and a step control circuit 4;

[0034] The first interface 1 is used to connect to an external power supply, the first interface 1 is electrically connected to the step control circuit 4 through the voltage control circuit 2, and the step control circuit 4 is connected to the passive electronic cigarette through the load protection circuit 8 and the second interface 2;

[0035] Wherein, the first interface 1 and the second interface 2 are configured to supply power to the passive electronic cigarette through the OTG function when connected to an external power source and a passive electronic cigarette respectively.

[0036] The first interface 1 of the power cord is used to connect an external power supply (that is, the external power supply provides power through the first interface 1). The power supply is regulated to a target voltage value, such as 5.1V, through the voltage control circuit 3. It can be specifically set according to actual conditions and is not specifically limited here. Then, the regulated power supply passes through the step control circuit 4. The step control circuit 4 adjusts the output voltage and current according to the power level set by the user. Specifically, a switch button can be set on the step control circuit 4 for user operation to adjust the output according to taste requirements.

[0037] Furthermore, the regulated power is transmitted to the power interface 7 of the passive electronic cigarette body through the second interface 2, and then transmitted to the heating wire 5 through the load protection circuit 8. When the user inhales, the pneumatic switch 6 senses the inhalation action, turns on the heating wire loop, and allows the current to pass through the heating wire 5 to heat the smoke liquid and generate steam. In this embodiment, the load protection circuit 8 ensures that the heating wire 5 operates within a safe current range to prevent overload.

[0038] It should be noted that, in this embodiment, please combine Figure 4 The power cord is detachably connected to the passive electronic cigarette, and the detachable design allows the user to replace different passive electronic cigarettes or power cords as needed. For example, when a new model of passive electronic cigarette is launched, the user only needs to replace the passive electronic cigarette to enjoy the improvements brought by the new technology without having to purchase a whole new electronic cigarette device. Its design not only reduces the long-term use cost of the user, but also improves the upgrade and expansion capabilities of the device.

[0039] In a possible embodiment of the present invention, the first interface 1 is one or more of typec, micro, lightning, and USB.

[0040] It should be noted that these interface types are the most common and widely used interface types in current electronic devices. By supporting multiple interface types, passive electronic cigarettes can be compatible with different types of external power devices, such as mobile phones, tablets, mobile power supplies, laptops, etc., which greatly improves the versatility and convenience of the device. Users do not need to worry about not being able to power the electronic cigarette due to interface mismatch. No matter what device is used, users can easily find a suitable power connection method.

[0041] In a possible embodiment of the present invention, it further includes: an LED lamp configured on the voltage control circuit 3 .

[0042] It should be noted that the LED light can display the power on or off status in real time, allowing users to understand the working status of the device at a glance. In electronic cigarette devices with a step control function, the LED light can be used to indicate the current voltage or power level. By observing the color or number of LED lights, users can quickly understand the working mode of the device, making it easier to adjust and select, thereby improving the user experience.

[0043] Based on the passive electronic cigarette and power cord provided by the utility model, the first interface configured on the power cord is connected to an external power supply, and the second interface is connected to the power interface and the atomization device body is powered based on the OTG function. When the pneumatic switch detects the user's inhalation, the heating wire circuit is turned on, so that the external power supply energizes the heating wire through the voltage control circuit, the step control circuit, and the load protection circuit, thereby solving the problem that the power supply voltage of the existing electronic cigarette gradually weakens with the increase of usage time, affecting the atomization effect of the electronic cigarette and user experience.

[0044] The above are only preferred implementations of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. All technical solutions under the concept of the present utility model belong to the protection scope of the present utility model.
