Background technique

Electronic cigarettes are currently widely used in some developed countries in Europe and the United States, mainly to replace traditional cigarettes. With the continuous improvement of our country's living standards. People are also constantly pursuing a higher quality of life, and gradually realize the serious harm of smoking, and smoking cessation has gradually become a common understanding. So alternatives like e-cigarettes are gradually gaining popularity.

E-cigarettes have the same appearance as cigarettes, taste similar to cigarettes, and even taste much more than ordinary cigarettes. Cigarettes can also suck out smoke, taste and feeling. Mainly used for smoking cessation and alternative cigarettes. E-cigarettes are also a non-combustible tobacco alternative product. It has some characteristics similar to ordinary cigarettes. It can refresh, satisfy smokers' pleasure and use habits developed over the years. However, it is essentially different from ordinary cigarettes. Electronic cigarettes do not burn, do not contain tar, and do not contain more than 460 kinds of chemical substances that can cause respiratory and cardiovascular system diseases when burned by ordinary cigarettes, thus eliminating the harmful substances in ordinary cigarettes. carcinogens. Thereby removing the carcinogens in ordinary smoke. It will not cause "second-hand smoke" harm to others and pollute the environment.

Electronic cigarettes are composed of two parts: an atomizer and a cigarette rod. The pod is composed of PCB board, rechargeable battery and various other circuits, and the atomizer is composed of atomizing device and pod. The authorized announcement number is: CN201878765U utility model patent discloses an atomizer (see Figure 4), the atomization device of the atomizer includes an atomizer main body 330, a liquid suction nozzle seat 310, a heating device 311 and a liquid guide One end of the liquid suction nozzle seat is provided with an atomization chamber 313, and the other end of the liquid suction nozzle seat is provided with a vent hole 314 communicating with the atomization chamber, and the heating device is fixed in the atomization chamber; the liquid guide assembly includes a suction The liquid nozzle and the liquid guide rope 320, one end of the liquid suction nozzle is inserted into the liquid storage cavity of the liquid storage box, the contact part between the liquid suction nozzle and the liquid storage box forms a liquid seal, and the other end of the liquid suction nozzle and the liquid suction nozzle seat The atomizing chamber is connected, the liquid guide rope is wound on the heating device 311, and the two ends of the liquid guide rope are introduced into the liquid suction nozzle.

The connecting assembly of the atomizing device 30 fixed on the other end of the housing 10 : the connecting assembly includes an atomizer main body 330 , a contact conductor 331 connected to the heating device 311 through wires, and a contact conductor base 332 . One end of the atomizer main body 330 located in the housing forms a cavity for accommodating and maintaining the atomization assembly, the sleeve 312 and other parts of the atomization assembly are fixed in this cavity, and the sleeve 312 and the cavity adopt an interference way to cooperate. The side wall of the atomizer main body is provided with an air inlet 333 communicating with the cavity, and this air inlet is used for conducting the atmosphere.

The atomizer main body 330 is first used to support the atomizing assembly, and secondly used to connect the power supply device.

Although the atomization device with the above structure can atomize the smoke liquid, it still has the following disadvantages:

First of all, the structure of the atomizing device is a heating element, which is powered by the battery to generate heat, so that the e-liquid next to it volatilizes and forms smoke, so that people can achieve the effect of "swallowing clouds and fog" when inhaling. The atomization device of the traditional electronic cigarette is integrally connected with the housing, and the atomization device breaks down within a few days of use, and cannot be replaced after being damaged, resulting in high usage costs for users. And if you have been using a separate atomization device for a long time, the taste will be very bad and the amount of smoke will be very small;

Secondly, the two contact conductors 331 are the conductive positive pole and the negative pole respectively, and the two ends of the electric positive pole and the negative pole are welded with the heating device 311 through wires. Since the outer diameter of the atomizer main body 330 is only 10 mm, these parts are assembled by It is done by hand, which creates higher difficulty for assembly and increases the labor intensity of workers;

Third, because the concentration of the e-liquid itself is relatively high, and there is a liquid guide rope in the liquid suction nozzle, the existence of the liquid guide rope makes the space of the liquid suction nozzle smaller, resulting in the slow discharge of the e-liquid when it flows. When the e-liquid is flowing, on the other hand, the heating device 311 is already working. Since the flow speed of the e-liquid cannot keep up with the working speed of the heating device, only a small part of the e-liquid can reach the heating device, which does not meet the normal requirements. The ratio of smoke to liquid is required, and the gas drawn into the mouth has a dry smell. This phenomenon is called dry burning.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment, the utility model is further described.

Referring to FIGS. 1 to 3 , the universal atomizing head 10 of the present invention includes a supporting seat 100 with an atomizing chamber, a heating device 101 , a conductive ring 102 and a liquid-conducting component. The support base 100 is made of ceramics. In order to install the heating device 101 , an atomization chamber 103 is provided in the support base 100 . In order to allow gas to enter the atomizing chamber 103 , a vent hole 104 is provided at the bottom of the support base 100 . The heating device 101 adopts electric heating wire made of metal, and the heating device 101 is fixed in the atomizing chamber 103 of the support base 100, and both ends of the heating device are welded with wires before being assembled into a general atomizing head. On the one hand, the conductive ring 102 is used as the conductive negative electrode of the universal atomizing head, and on the other hand, it is used to load other parts.

Referring to Fig. 1, after the support base 100 is fixed in the middle of the cavity of the conductive ring 102, the wire connected to one end of the heating device is compressed between the conductive ring and the support base, so that the wire and the conductive ring maintain good contact. This method does not need to manually weld the conductive negative electrode and the heating device, which can save one process and reduce the labor intensity of workers. Referring to FIG. 3 , in order to reduce the adverse effect of a little atomized e-liquid flowing back onto the universal atomizing head on the replaceable universal atomizing head, a liquid-absorbing component 105 is wrapped on the outer surface of the support base 100 . The liquid part is a nickel mesh. After wrapping up this liquid-absorbing part, when the support base 100 is installed in the middle part of the conductive ring 102 cavity, the wire connected to one end of the heating device can also be pressed between the conductive ring and the nickel mesh, so that the wire and the conductive ring Keep up the good touch.

Referring to FIGS. 1 to 3 , the liquid guiding component includes a liquid guiding rope 106 , a liquid guiding nozzle 107 and a liquid guiding nozzle seat 108 integrated with the liquid guiding nozzle. One end of the liquid guide rope is located in the liquid guide liquid 107, and the other end of the liquid guide rope 106 is connected to the heating device after passing through the liquid guide nozzle seat 108. In order to improve the heating efficiency of the heating device for the smoke liquid, the liquid guide rope is preferably Wrapped on the upper part of the heating device 101 (as seen from the figure), the flow path of the e-liquid is almost in the entire heating device. Therefore, after being arranged in this way, the heating device 101 with heat generation can improve the protection of the e-liquid. Heating efficiency. Although the liquid guide rope 106 has helped the uniformity of the smoke liquid flowing to the heating device, due to the existence of the liquid guide rope, the flow speed of the smoke liquid has slowed down, so the inner hole wall surface of the liquid guide nozzle 107 and the liquid guide nozzle seat 108 Liquid guiding grooves 109 are arranged on both sides, and the smoke liquid is drained through the liquid guiding grooves to increase the flow rate of the smoke liquid, so as to achieve the purpose of having a proper ratio between the provided smoke liquid and the heating device when heating, and avoid dry burning. The liquid guide nozzle 107 and the liquid guide nozzle seat 108 are actually integrally formed, so the liquid guide groove 109 on the liquid guide nozzle 107 and the liquid guide nozzle seat 108 is a connected groove. The number of liquid guide grooves 109 is related to the arrangement of the heating device. When the liquid guide groove 109 on the liquid guide nozzle and the liquid guide nozzle seat is one, the heating device 101 is assembled in the atomization chamber of the support seat and the two The ends are on the same horizontal line. The reason for adopting this method is that when the heating device 101 is on the same horizontal line, the path for the e-liquid to flow along the surface of the heating device is short, so the atomization speed is fast during heating. If there is too much e-liquid There will be liquid leakage, therefore, only one liquid guide groove can meet the requirements, and the replaceable universal atomizing head with one liquid guide groove is suitable for people who smoke electronic cigarettes in a small amount. If there are two or three liquid guiding grooves on the liquid guiding nozzle and the liquid guiding nozzle seat, the heating device 101 needs to be arranged in the atomization chamber of the supporting seat with one end high and the other end low, that is, the heating device is placed in the support seat. The atomization chamber of the support seat 100 is arranged in an inclined state. The reason for adopting this method is that because the heating device is arranged in an inclined state in the atomization chamber of the support seat 100, the flow path of the e-liquid is extended, so it will not In the case of liquid leakage, therefore, by increasing the number of liquid guide grooves to increase the amount of smoke liquid provided, the amount of smoke is also increased. The universal atomizing head with more than two liquid guide grooves is suitable for people who smoke a lot of electronic cigarettes. Because the universal atomizing head of the present invention is replaceable, the same person can choose a universal atomizing head with a specific number of slots according to the demand of the amount of smoke, which is quite convenient for the user. One end of the liquid guide seat 108 is inserted into one end of the conductive ring 102 cavity. The liquid guide seat 108 is cylindrical in appearance, and a section body is cut off along the axial direction on the outer circumference of the liquid guide seat 108. In this way, After the liquid guide seat 108 is installed in the conductive ring 102, a channel appears between the liquid guide seat 108 and the conductive ring 102, and this channel is for the smoke formed after the liquid smoke is atomized to pass through.

Referring to FIGS. 1 to 3 , a conductive component is provided at the other end of the cavity of the conductive ring 102 , and the conductive component includes a conductor 110 and an insulator 111 . The conductor 110 is the positive pole of the universal atomizing head, the conductor is welded to the wire connected to the other end of the heating device, the conductor 110 is fixed on the insulator 111, the conductor 110 is in the shape of a ring, and the conductor 110 is installed on the axial end face of the insulator In the ring mounting groove set above. The insulator is fastened in the cavity of the conductive ring, and an air hole is arranged on the insulator, and the air hole is used for negative-pressure airflow to pass through when smoking.
