Background technique

As the control and restrictions on tobacco around the world become more stringent, the demand for electronic cigarettes is increasing year by year. As a substitute for traditional tobacco, electronic cigarettes can not only simulate the sensory experience of smoking, but also cause far less damage to health than smoking traditional tobacco.

Electronic cigarettes usually include pods and rods. The pod is installed on the tobacco rod and can generate smoke that is inhaled by the human body. The pod is equipped with an oil storage chamber, an air channel, an atomization chamber and an atomization core. Smoke oil for generating smoke is arranged in the oil storage bin. E-liquid enters the atomization chamber through the atomization core and is atomized into smoke, and the smoke is inhaled by the user through the airway.

The user experience of the atomizing device used as a pod in the related art is poor, which is usually due to: the airflow channel in the upper cover is too narrow in the width direction, so that the resistance when the user smokes will be reduced when the atomizing core of the atomizing device is working. The increase will cause the flow rate of the smoke in the atomization chamber of the atomization device to be faster, and the faster flow rate of smoke will condense into liquid e-liquid when it collides with the inner wall of the atomization device, so that the user can easily inhale the liquid e-liquid when smoking.

Detailed ways

Embodiments of the present disclosure are described in detail below, and the embodiments described with reference to the accompanying drawings are exemplary. The following describes an atomizing device 100 for electronic cigarettes according to an embodiment of the first aspect of the present disclosure with reference to FIGS. 1-16 .

As shown in FIGS. 1-16 , the atomizing device 100 for electronic cigarettes according to the embodiment of the first aspect of the present disclosure includes a casing 1 and an atomizing core fixing part 2 .

Specifically, the casing 1 is provided with an oil storage bin 111, an air passage 112, and an atomization chamber 113 communicating with the air passage 112; The suction port 114. The atomizing core fixing part 2 is arranged in the casing 1, the atomizing core fixing part 2 separates the oil storage bin 111 and the atomizing bin 113, and the atomizing core fixing part 2 is formed with a mounting groove 211 and a communication channel 221, and the inside of the mounting groove 211 An atomizing core 9 is provided, and the atomizing core 9 communicates with the oil storage bin 111 and the atomizing bin 113 respectively. The atomizing core 9 is used to atomize the medium to be atomized in the oil storage bin 111, and the communication channel 221 is located in the installation groove 211 , one end of the communication channel 221 communicates with the atomization chamber 113 , and the other end of the communication channel 221 extends toward the installation groove 211 and communicates with the air channel 112 .

For example, in the example shown in Fig. 1 and Fig. 2, the air passage 112 can be arranged in the middle part of the housing 1, and the oil storage bin 111 is located on the outer periphery of the air passage 112, and the oil storage bin 111 is used to hold the liquid medium to be atomized such as smoke. Oil. The atomizing core fixing part 2 is located on the side of the air passage 112 adjacent to the air inlet 121, and the installation groove 211 and the communication channel 221 can be spaced apart from each other along the length direction of the atomizing core fixing part 2 (for example, the left-right direction in FIG. 9 ). The shape of the installation groove 211 is adapted to the shape of the atomizing core 9 so as to securely install the atomizing core 9 on the fixing part 2 of the atomizing core. The atomizing chamber 113 can be located on the side of the atomizing core fixing part 2 away from the oil storage chamber 111, and the liquid medium to be atomized in the oil storage chamber 111 can flow to the atomizing chamber 113 after being atomized by the atomizing core 9, and the inhalation The port 114 is arranged on the top of the casing 1 and communicates with the air passage 112 , and the air inlet 121 is arranged at the bottom of the casing 1 and communicates with the atomizing chamber 113 .

Wherein, by making the above-mentioned other end of the communication channel 221 extend toward the direction of the installation groove 211 and communicate with the air passage 112, compared with the traditional atomization device of the electronic cigarette, the atomization medium in the atomization chamber 113 can be guaranteed to be smooth. While flowing to the air channel 112, the width of the above-mentioned one end of the communication channel 221 can be reduced, so that the length of the atomizing core fixing part 2 can be shortened, and the width of the housing 1 can be shortened (for example, in the left and right direction in FIG. 1 ), So that the design of the shell 1 can meet the design of ultra-thin width, so as to better meet the needs of users, and at the same time, the width of the other end of the communication channel 221 can be increased, so that when the atomizing device 100 is applied to electronic cigarettes, the Reduce the resistance of the electronic cigarette when smoking, slow down the flow rate of the atomizing medium to reduce the formation of condensate such as e-liquid, which can prevent the user from inhaling liquid e-liquid when smoking, and improve the user experience.

The following describes the working process when the atomizing device 100 is applied to electronic cigarettes with an example.

After the atomizing device 100 is combined with the cigarette rod, the user inhales air through the suction port 114. At this time, the pneumatic sensor (such as a microphone) in the cigarette rod senses, so that the power supply in the cigarette rod and the atomizing core 9 are electrically connected. The atomizing core 9 works, for example, the atomizing core 9 is heated, and the medium to be atomized in the oil storage chamber 111, such as smoke oil, moves toward the atomizing chamber 113 and is heated by the atomizing core 9, forming smoke in the atomizing chamber 113 (including But not limited to aerosol, suspended liquid, low-temperature steam and volatile gas), at the same time, the outside air enters the atomization chamber 113 through the air inlet 121 and mixes with the smoke in the atomization chamber 113, and the mixed smoke passes through the communication channel 221 and the airway 112 are inhaled by the user through the inhalation port 114, so as to realize the use requirement of the user. When the user stops inhaling from the suction port 114, the medium to be atomized in the oil storage compartment 111, such as e-liquid, will stop entering the atomization compartment 113 from the atomizing core 9, so as to avoid the atomization medium in the oil storage compartment 111 Ineffective consumption of medium improves the utilization rate of the medium to be atomized. Among them, what needs to be explained here is that some electronic cigarettes set the atomizing device 100 and the tobacco rod into a separate structure, and the two are detachably combined, and some electronic cigarettes set the atomizing device 100 and the tobacco rod in a non-detachable structure. No specific limitation is made here.

According to the atomizing device 100 for electronic cigarettes according to the embodiment of the present disclosure, an oil storage bin 111, an air passage 112, and an atomizing bin 113 communicating with the air passage 112 are arranged in the casing 1, and the atomizing core 9 is installed in the atomization chamber 113.

It communicates with the oil storage bin 111. Specifically, a communication cavity 214 communicating with the atomization chamber 113 is formed on the atomizing core fixing part 2, and at least one through hole 215 is formed on the side wall of the atomizing core fixing part 2, and the through hole 215 communicates with the communication cavity 214, At least one communicating groove 216 is formed on the outer peripheral surface of the atomizing core fixing part 2, one end of the communicating groove 216 communicates with the through hole 215, and the other end of the communicating groove 216 runs through the side of the atomizing core fixing part 2 adjacent to the oil storage tank 111 On the surface, the communication groove 216 cooperates with the third sealing member 5 to form a ventilation channel.

Wherein, when the pressure of the atomization chamber 113 is greater than the pressure of the oil storage chamber 111, under the action of the pressure difference between the two, the ventilation channel is opened, and the pressure of the atomization chamber 113 is reduced to make the atomized oil in the oil storage chamber 111 The medium can flow to the atomizing core 9 smoothly. When the pressure of the atomization chamber 113 is not greater than the pressure of the oil storage chamber 111, the pressure between the oil storage chamber 111 and the atomization chamber 113 is balanced at this time, and the ventilation channel is closed to ensure that the pressure of the oil storage chamber 111 is greater than that of the oil storage chamber 111. The pressure of the atomization chamber 113 enables the medium to be atomized to flow smoothly to the atomization core 9 . Therefore, the pressure difference between the oil storage bin 111 and the atomization bin 113 can be effectively adjusted through the air exchange channel, so that the pressure of the oil storage bin 111 can be greater than the pressure of the atomization bin 113, ensuring that the atomized medium can be smoothly sprayed.

The air channel is used to prevent the medium to be atomized in the oil storage bin 111 from flowing from the air exchange channel to the atomizing bin 113 .

It should be noted that a certain amount of force is required to push the elastic deformation of the sealing part 51, so the pressure difference between the atomization chamber 113 and the oil storage chamber 111 can push the sealing part 51 to undergo elastic deformation, and the ventilation channel can be opened. That is to say, by setting the material and structure of the sealing part 51, the pressure of the atomization chamber 113 can be made greater than the pressure of the oil storage chamber 111, and at the same time, the sealing part 51 can be pushed to open the ventilation channel, or the pressure of the atomization chamber 113 can be opened.
