Description

A heating and atomizing electronic cigarette powered by a capacitor

technical field

The utility model relates to an electronic cigarette with a heating and atomizing function, in particular to a heating and atomizing electronic cigarette powered by a capacitor.

Background technique

In recent years, the harm caused by traditional smoking to the smoker himself and the people around him has become more and more recognized by people. For this reason, government departments in many countries or regions have issued regulations one after another to expressly prohibit smoking in public places. However, for smokers with cigarette dependence (or addiction), quitting smoking will be a very difficult and painful long-term process, and it is impossible to achieve immediate results and overnight.

In order to meet the needs of smoking cessation, various forms of cigarette substitutes have been launched on the market, such as nicotine spray, nicotine syrup, nicotine patch, nicotine chewing gum, electronic cigarettes that can atomize nicotine solution, etc. Among them, the electronic cigarette can realize the effective atomization of the nicotine solution, thereby retaining the characteristics of the traditional smoking method during the smoking process, and can satisfy the habit of the smoker to a greater extent. In addition, the main component of the smoke produced by electronic cigarettes is nicotine, which does not contain carcinogens such as tar that endanger human health. Therefore, e-cigarettes have continuously won the favor of consumers in recent years, and are gradually becoming a substitute for cigarettes, playing an increasingly important role in smoking cessation.

The existing technical solutions for electronic vaping mainly include two categories: heating atomization and ultrasonic atomization. The application number is 03242914.2, and the Chinese utility model patent titled "a pen-type micro-steam generator" proposes a solution for heating and atomizing liquid in a small cavity, which is implemented in conventional liquid and nicotine The atomization of the solution can develop the function of delivering nicotine vapor to the nasal cavity, oral cavity and other parts. Different from the heating atomization scheme, the application number is 03111173.4, and the Chinese invention patent titled "A Non-combustible Electronic Atomized Cigarette" proposes an ultrasonic atomization scheme, which is similar to that of a household humidifier. same principle. Due to the high atomization efficiency of ultrasonic atomization technology, it has been widely used in various atomization fields, such as humidifiers, nebulizers, medical atomizers, ultrasonic atomization therapeutic instruments, ultrasonic atomization inhalers, ultrasonic beauty instrument, aromatherapy nebulizer, etc. However, due to volume limitations, it is still quite difficult to achieve ultrasonic atomization on electronic cigarettes with existing technologies. In fact, because of this, almost without exception, the current e-cigarette products on the market have finally adopted a heating atomization solution instead of the high-tech ultrasonic atomization advertised.

Although heating atomization has been successfully used in electronic cigarette products, most of the heating methods currently used are resistance wire heating. The heating efficiency of this heating method is relatively low, so there are problems of small atomization amount and insufficient energy utilization. The applicant once proposed a solution for nanoscale ultra-fine space heating atomization in 2007 (application numbers are 200710121524.6 and 200720173030.8, a Chinese invention patent application named "electronic cigarette with nanoscale ultra-fine space heating atomization function" and utility model patents), which can significantly improve the efficiency of heating atomization, but its production cost is relatively high.

In addition, it is not difficult to find that most of the patents related to e-cigarettes that have been published so far use rechargeable batteries to provide power for their atomizers. As a substitute for cigarettes, e-cigarettes first need to be compact in structure, otherwise they are too heavy to be carried or used. Rechargeable batteries have the advantage of strong power endurance, but they have obvious disadvantages when used in smoking cessation products. The specific manifestations are as follows: firstly, the rechargeable battery is heavy, which is not conducive to reducing the overall weight of the electronic cigarette; secondly, the rechargeable battery has a strong battery life, making the sustainable smoking time of the electronic cigarette much longer than the smoking time of a traditional cigarette, which will lead to It is difficult for ex-smokers to control the amount of smoking, which makes them unable to quit smoking effectively. In addition, rechargeable batteries take a long time to charge, generally taking up to several hours. Ex-smokers need to purchase multiple sets of products to meet their needs, thereby increasing the cost of smoking cessation.

Considering that most of the power supply and smoke body control units of existing electronic cigarettes adopt an integrated design scheme, which is easy to cause the disadvantage of automatically connecting the circuit due to vibration during transportation or carrying, the utility model adopts a plug-in method to connect the power supply part and the smoke body Partially separated to prevent the automatic connection of the circuit during transportation or carrying. In addition, the existing electronic cigarettes use threads to connect the atomizer and the cigarette body.

It can be seen from Figures 1-3 that the power supply part and the cigarette body part of the electronic cigarette of the utility model are separated structures for easy insertion and connection, which is convenient for charging and avoids the problem of automatic circuit connection that may be caused during transportation or carrying. In this embodiment, the shape and size of the electronic cigarette are similar to those of conventional cigarettes, and the usage habits of smokers will not be changed basically.

As shown in FIG. 3 , the electronic cigarette heated and atomized by capacitor power supply provided by the utility model is composed of a power supply part, a cigarette body part and a hollow mouthpiece.

Specifically, the power supply part (as shown in Figure 1) includes: a power supply 1 powered by a capacitor; an indicator light 2 installed at the rear end of the power supply 1; a pair of electrode plug connectors 3 and a lead wire plug connector installed at the front end of the power supply 1 4.

As shown in Figure 3, the power supply part and the smoke body part are placed separately or connected through the electrode plug connector 3, the lead wire plug connector 4, the electrode plug connector 6, and the lead wire plug connector 7 in a plug-in manner, and a mechanical bayonet is provided at the connection type anti-off device; the front end of the cigarette body part and the rear end of the hollow cigarette holder 13 are connected by plug or thread; the power supply 1, the indicator light 2, the control circuit module 8 and the heating and atomizing device 9 are electrically connected in sequence.

The functional principle of each component is described in detail below:

The power supply part is charged by an external capacitor charger, which can be an AC-DC conversion charger, a computer USB interface charger, a DC storage battery (or rechargeable battery) charger, a solar battery charger or a human charging (( Such as hand-held, hand-operated and other charging methods). When charging, the power supply part is pulled out from the smoke body part, and charged through the electrode plug connector 3. It should be pointed out that the charging interface of the present invention is not limited to the electrode plug connector 3. The charging interface can also be set at the front end of the power supply part (close to the indicator light 2), or the side of the power supply part. A major feature of the electronic cigarette charging method of the utility model is manual charging, because the capacitor has the advantage of fast charging This makes this charging method practical, and it is almost unrealistic to use this charging method on conventional rechargeable batteries.

The power supply 1 is powered by a single supercapacitor, or multiple supercapacitors connected in parallel, or multiple supercapacitors connected in series. Supercapacitor is a new high-efficiency energy storage device that is different from traditional capacitors in recent years. It is characterized by light weight, high energy storage density, small size, long life, low internal resistance, large capacitance value, especially the charging and discharging speed. Much better than conventional batteries. Due to the ability to store a large amount of electrical energy in a small space for a long time, supercapacitors have the ability to provide power for small electrical equipment, but also show unique advantages that conventional rechargeable batteries do not have, such as internal resistance is significantly smaller than rechargeable batteries, charging The speed is much faster than rechargeable batteries, etc., which brings great convenience for e-cigarette users to charge or smoke at any time according to their personal preferences. So far, electronic cigarette products basically use rechargeable batteries as the power source, and their charging speed is very slow, and it takes several hours to complete a charge, which brings great inconvenience to users; while the charging process of supercapacitors is very fast, only 2 Minutes, good real-time performance, can greatly facilitate users. In addition, conventional rechargeable batteries will cause secondary pollution to the environment, while supercapacitors do not have this problem. Therefore, supercapacitors are an ideal high-efficiency and long-life green power supply for e-cigarette products that are used in a large amount.

Indicator light 2 can be made by light-emitting diode (LED), can select different light-emitting colors according to need, and indicator light is connected with power supply part, and it is switched on and off by control circuit module 8 control. When smoking, the indicator light 2 is on; when not smoking, the indicator light 2 is off.

The electrode plug connector 3 of the power supply part is connected to the electrode plug interface 6 of the cigarette body part, and the lead wire plug connector 4 of the power supply part is connected to the lead wire plug connector 7 of the smoke body part by plugging, and a mechanical bayonet type anti-loosening device is provided between them , the plug-in method has both electrical and mechanical connection functions. Compared with the existing threaded connection method, this connection method is more convenient in operation and reliable in connection, and has obvious advantages, and has never been used in electronic cigarettes or other DC consumer electronic devices before. In addition, it needs to be pointed out that the existing capacitors or supercapacitors are generally connected to electrical devices by welding. The quick plug-in method adopted by the utility model is a new connection method for capacitor energy storage equipment. The connection method is convenient for quick connection and separation with the electrical device. On the one hand, when used in electronic cigarette products, it can effectively solve the problem of automatic connection during transportation or carrying, and on the other hand, it has the advantages of convenient and quick use.

Among them, the pressure difference sensing element is used to sense the micro pressure difference generated by the pumping action to switch on the control circuit. 2. Control the electric circuit formed by the circuit module 8 and the heating and atomizing device 9; otherwise, disconnect the electric circuit. In order to enable the power supply assembly to provide stable power output (constant voltage or constant current output), the control circuit of the utility model also includes a step-up conversion circuit or a step-down conversion circuit and a step-up conversion circuit at the same time.

And, no delay circuit is established in the utility model control circuit. In the existing electronic cigarettes, a delay circuit is generally used to increase the atomization amount of the smoke liquid. On the one hand, this method was adopted in the early stage because of the low efficiency of the atomization method used, and on the other hand, because the discharge speed of the rechargeable battery used is limited. , which further leads to low heating atomization efficiency. Although this method can make up for the shortcoming of the small amount of atomization in the prior art to a certain extent, the atomization time is significantly longer than the suction time, which leads to differences from traditional smoking methods. On the one hand, the utility model can significantly enhance the heating and atomization efficiency through the improvement of the atomization technology; change.

The hollow tobacco rod 5 is a hollow thin-walled tube, which can be made of metal materials such as stainless steel, copper, aluminum, titanium alloy, magnesium alloy, etc., or can be made of non-metallic materials with poor thermal conductivity such as polytetrafluoroethylene, plastic, etc. It can be made of transparent materials such as glass, plexiglass, transparent ceramics, etc., so that users can see the smoke generation process with their own eyes, so as to experience the fun that conventional smoking methods cannot feel.

Preferably, the tobacco rod 5 can be made of low thermal conductivity material such as polytetrafluoroethylene (thermal conductivity is 0.2W/m·°C) and the like. The tobacco rods of existing electronic cigarette products generally use stainless steel pipes (thermal conductivity is about 16W/m·℃) or copper pipes (thermal conductivity is 398W/m·℃). Since the thermal conductivity of polytetrafluoroethylene is much lower than that of stainless steel and copper, it can play a significant role in heat insulation and prevent the heat generated by heating the atomizing device from being transmitted to the surface of the cigarette rod. In this way, on the one hand, it can effectively alleviate the heating problem of the tobacco rod of the existing electronic cigarette products, and on the other hand, it can also improve the feel of the electronic cigarette (if the material of stainless steel or copper is used, when the temperature is low, holding the electronic cigarette will feel cold and uncomfortable. Feel). In addition, the density of PTFE is about 2200kg/m ³ , that of stainless steel is about 7800kg/m ³ , and that of copper is about 8900kg/m ³ .

Optionally, a gap or a heat insulating material may be provided between the hollow tobacco rod 5 and the heating atomizing device 9 to further realize the effect of heat insulation.

When the hollow cigarette holder 13 is removed, the nicotine liquid filling port 11 needs to be exposed outside the hollow tobacco rod 5, so as to add liquid nicotine solution. The nicotine filling port 11 is sealed with a gland to prevent liquid leakage; when adding nicotine, the gland can be temporarily uncovered. The hollow cigarette holder 13 is installed on the end of the tobacco rod 5 close to the nicotine liquid storage chamber 12, and is connected by a plug-in connection or a screw connection, and the replacement is very convenient. The way of adding liquid to the nicotine liquid storage chamber 12 is not only the above-mentioned design scheme, but also a pen cartridge design, which is similar to the way a fountain pen absorbs ink. The sponge body in the nicotine liquid storage bin 12 is a sponge body of stainless steel fiber, copper fiber, gold fiber, platinum fiber, silver fiber, non-woven fabric fiber, ceramic fiber, glass fiber, activated carbon or porous ceramic. Optionally, the liquid suction head (10) is a liquid suction head made of nickel foam.

The electronic cigarette of the present utility model can also be provided with an air intake channel between the cigarette holder 13 and the cigarette rod 5, and can also be provided with an air inlet channel in the electrode insertion port 6 or the lead super interface 7, or between the cigarette holder 13 and the cigarette rod 5 at the same time. Air intake passages are set between the electrode insertion port 6 and the lead wire super-interface 7 to reduce the suction resistance. When smoking, the air flows into the hollow tobacco rod 5 through the air inlet, and is mixed with atomized nicotine gas to form aerosol-like smoke. The difference between this air intake channel setting method and the existing electronic cigarette air intake channel arrangement method is that the air intake channel of the existing electronic cigarette is generally arranged in the threaded connection gap, or the air intake hole is specially set up.

The shape and size of the electronic cigarette heated and atomized by capacitor power supply of the utility model can be similar to conventional cigarettes, cigars or pipes, and can also be designed in various personalized shapes.

The electronic cigarette provided by the utility model adopts a split-designed power supply part to supply power to the heating atomization part and the indicator light with efficient atomization function, which embodies many outstanding advantages different from the prior art. Due to the use of capacitor power supply, it is lighter in weight compared to traditional lithium batteries.

Due to the use of capacitors, the charging process of the capacitor is generally completed within 1 to 2 minutes, which can well meet the requirements of fast charging, and the power of the capacitor can reach the atomization amount equivalent to that of a traditional cigarette after one charge. It is easy to control the amount of smoking while satisfying the smoking craving of ex-smokers; in addition, the capacitor also has the advantage of light weight; using PTC, porous ceramic resistors, aluminum foam or metal fibers to make electric heating atomizers can significantly enhance the atomization effect. So far, there is no electronic cigarette that uses capacitors to supply power to PTC, porous ceramic resistors, metal fiber or resistance wire atomizers in domestic and foreign literature and patents. A technical solution for fast charging of electronic cigarettes with fiber or resistance wire atomizers.
