[0048] Hookah is a tobacco product that is smoked after filtering water (or other liquids). Using hookah equipment, you can smoke tobacco mixed with sweeteners (such as dried fruits, molasses, honey or spices), so smokers can freely decide the flavor of the hookah they smoke. Hookahs are usually equipped with hookahs. When using hookahs, the hookahs need to be heated. At the same time, the liquid in the hookah will produce a "gurgling" sound due to heating. Combined with the aroma of the smoke produced by the hookah, it can increase the user's pleasure when using the hookah.

[0049] First embodiment

[0050] like Figure 1-4 As shown, this embodiment provides an electronic cigarette, including an atomizer assembly 10, a control assembly 20 and a sound-generating device 30, the atomizer assembly 10 is provided with an atomizer channel 101; the control assembly 20 includes a power supply 23 and a circuit board 22, the atomizer assembly 10 and the power supply 23 are both connected to the circuit board 22; the sound-generating device 30 is located directly below the atomizer assembly 10, and the sound-generating device 30 is electrically connected to the circuit board 22; wherein, when the sound-generating device 30 is powered on, the sound-generating device 30 can simulate the sound of a hookah.

[0051] In the electronic cigarette of the present application, since the smoke generated when the electronic cigarette is used has a fragrance, and the hookah sound produced by the sound-generating device 30 is combined, the use of hookah can be imitated to a high degree, satisfying the user's experience of using hookah.

[0052] like Figure 1-3 As shown, in the present embodiment, the atomization assembly 10 includes a suction nozzle 11, an oil storage bin 16, oil storage cotton 13, an upper sealing plug 12, a lower sealing plug 17, an oil blocking tube 14 and an atomization core 15. The oil storage bin 16, the upper sealing plug 12 and the lower sealing plug 17 enclose an oil storage cavity (not shown in the figure), the oil storage cotton 13 is installed in the oil storage cavity, the oil storage cotton 13 is provided with a smoke channel (not shown in the figure) running through the upper and lower surfaces thereof, the oil blocking tube 14 is embedded in the smoke channel and is connected to the suction nozzle channel (not shown in the figure) of the suction nozzle 11, and an atomization hole (not shown in the figure) is opened on the shell wall of the oil blocking tube 14, and the smoke oil of the oil storage cotton 13 can enter the atomization core 15 through the atomization hole. The atomizer core 15 includes a heating element (not shown) and oil-conducting cotton (not shown) wrapped layer by layer from the inside to the outside. The heating element is connected to the circuit board 22 through two electrodes (not shown). The heating element can heat the smoke oil into smoke after being powered. The oil-conducting cotton and the oil-storing cotton 13 are made of cotton materials such as fiber cotton, absorbent cotton, and organic cotton. They have more fluffy pores and can absorb more smoke oil, providing sufficient smoke oil for the heating element.

[0053] In one embodiment, the circuit board 22 is provided with a control circuit, and the control circuit is used to control the single working time of the sound-emitting device 30; when the working time of the sound-emitting device 30 is longer than the preset working time, the control circuit drives the sound-emitting device 30 to stop making sounds. In this embodiment, the preset working time can be set according to the needs of the user, or it can be set to a fixed value when the electronic cigarette leaves the factory. When the single working time of the sound-emitting device 30 is longer than the preset time, the control circuit drives the sound-emitting device 30 to power off and stop making sounds. Among them, the single working time refers to the cumulative total time that the sound-emitting device continuously makes sounds starting from a certain time point.

[0054] In one embodiment, the atomizing assembly 10 is provided with a heating element, which is electrically connected to the circuit board; when the working time of the sound-generating device 30 is greater than the preset working time, the control circuit drives the heating element to cut off the power.

[0055] In this embodiment, the preset working time may be 8-12 seconds, for example, 8 seconds, 9 seconds, 9.5 seconds, 10 seconds, 11 seconds or 12 seconds, wherein the preset working time is preferably 10 seconds. When the power-on time of the heating element is too long, the heat generated by the heating element is too much, which may easily lead to problems such as overheating of the heating element and insufficient oil supply. By setting the preset working time, this embodiment associates the working time of the sound-emitting component with the working time of the heating element. The user can judge that the heating element is powered off by the fact that the sound-emitting component does not make a sound, and can also avoid problems such as overheating of the heating element and insufficient oil supply.

[0056] like Figure 2 and Figure 3 As shown, in one embodiment, a bottom cover 40 is also included, and the bottom cover 40 is provided with an air inlet hole 201, and an air inlet channel 202 connecting the air inlet hole 201 and the atomization channel 101 is provided between the bottom cover 40 and the atomization assembly 10. In the present embodiment, a housing 50 is also included, and the housing 50 is connected to the bottom cover 40 and encloses a mounting space (not shown), and the atomization assembly 10 and the control assembly 20 are both accommodated in the mounting space.

[0057] like Figure 4As shown, in one embodiment, a microphone 21 is further included, and the microphone 21 is electrically connected to the circuit board 22. The bottom cover 40 is provided with a microphone cavity (not shown) connected to the air inlet channel 202. The microphone 21 is accommodated in the microphone cavity, and the microphone cavity is divided into an upper cavity 212 and a lower cavity 211. The lower cavity 211 is connected to the air inlet channel 202. The microphone 21 is used to detect the air pressure difference between the upper cavity 212 and the lower cavity 211, and drive the atomization assembly 10 to start or stop.

[0058] In one embodiment, a socket assembly 60 is further included. A connecting channel 601 is formed between the socket assembly 60 and the microphone 21. One end of the connecting channel 601 is connected to the upper cavity 212, and the other end is exposed.

[0062] Second embodiment

[0063] The electronic cigarette of this embodiment is basically the same as the electronic cigarette of the first embodiment, except that:

[0064] like Figure 5-8 As shown, in this embodiment, the bottom cover 40 is provided with a mounting hole 421 connected to the atomization channel 101, the mounting hole 421 is located directly below the atomization channel 101, and the sound-generating device 30 is detachably connected to the mounting hole 421. When using the electronic cigarette, the sound-generating device 30 can be installed in the mounting hole 421 so that the electronic cigarette can imitate the "gurgling" sound of the hookah; or the sound-generating device 30 can be removed from the mounting hole 421 so that the electronic cigarette does not produce any sound. Whether to use the sound-generating device 30 to produce the hookah sound can be switched at will according to the user's choice, which improves the user's experience. Among them, after the sound-generating device 30 is removed from the mounting hole 421, the atomization channel 101 can take in air from the mounting hole 421.

[0065] like Figure 5 and Figure 6 As shown, a avoidance hole 422 connected to the mounting hole 421 is provided on the bottom surface of the bottom cover 40, and a prying cover 321 which can be accommodated in the avoidance hole 422 is provided at the bottom of the sound-generating device 30, and the sound-generating device 30 is conveniently removed from the mounting hole 421 by prying the cover 321. In order to improve the stability of the connection between the sound-generating device 30 and the bottom cover 40, a magnet (not shown) is provided at the bottom of the mounting hole 421, and the shell of the sound-generating device 30 is made of metal material, or a magnet is also provided at the corresponding position of the sound-generating device 30.

[0066] In one embodiment, the circuit board 22 is provided with a contact point (not shown), and the sound-generating device 30 is provided with an electric contact guide pin (not shown). When the sound-generating device 30 is accommodated in the mounting hole 421, the electric contact guide pin can abut against the contact point. In this embodiment, the sound-generating device 30 includes a sound-generating device 31 and a sound-generating housing 50. The sound-generating device 31 includes a voice chip (not shown) and a speaker (not shown). The electric contact guide pin and the speaker are electrically connected to the voice chip. The voice chip stores a program for simulating hookah, and can drive the speaker to produce a "gurgling" sound after power is connected. The sound-generating housing 50 is provided with an installation cavity (not shown), and the sound-generating device 31 is accommodated in the installation cavity. A sound-generating hole 301 connected to the installation cavity is provided on the bottom surface of the sound-generating housing 50, and the sound generated by the speaker can be transmitted outward through the sound-generating hole 301. The sound-generating device 30 is powered by the circuit board 22. When the sound-generating device 30 is removed or the sound-generating device 30 is not properly installed, the sound-generating device 30 cannot work.

[0067] In one embodiment, when the sound-generating device 30 is accommodated in the mounting hole 421 and the electric contact needle abuts against the contact point, the sound-generating device 30 can completely cover the mounting hole 421. In this embodiment, a sealing ring is provided on the outside of the sound-generating device 30 or the inside of the mounting hole 421. When the sound-generating device 30 is correctly installed, the sealing ring can ensure good air tightness between the sound-generating device 30 and the mounting hole 421, and there is no air flow in the mounting hole 421. The atomization channel 101 can only take in air through the air inlet channel 202.

[0068] like Figure 7 and Figure 8 As shown, in one embodiment, one end of the air inlet channel 202 connected to the atomization channel 101 is an air outlet 204, and the orthographic projection of the air outlet 204 on the bottom cover 40 does not coincide with the orthographic projection of the atomization channel 101 on the bottom cover 40. In this embodiment, since the mounting hole 421 is located directly below the atomization channel 101, and the air outlet 204 is not located directly below the atomization channel 101, when the sound-generating device 30 is removed from the mounting hole 421, the atomization channel 101 only inhales air through the mounting hole 421 but not through the air inlet channel 202.

[0069] like Figure 8 As shown, the second partition 72 is provided with an air inlet 721 connecting the mounting hole 421 and the atomization channel 101, and the diameter of the air inlet 721 is larger than the diameter of the air outlet 204. When the sound-generating device 30 is removed from the mounting hole 421, the atomization channel 101 only takes in air through the mounting hole 421 and the air inlet 721, but not through the air inlet channel 202 and the air outlet 204. At this time, the air pressure in the air inlet channel 202 does not change, so there is no air pressure change in the upper cavity 212 and the lower cavity 211, and the microphone 21 cannot drive the atomization channel 101 to start. By removing the sound-generating device 30, the electronic cigarette is locked, so that the electronic cigarette of this embodiment has a child lock function.

[0070] Third embodiment

[0071] The electronic cigarette of this embodiment is basically the same as the electronic cigarette of the second embodiment, except that:

[0072] In one embodiment, when the sound-emitting device 30 is accommodated in the mounting hole 421, there is a first state and a second state: in the first state, the electric contact needle abuts against the contact point, and the sound-emitting device 30 is electrically connected to the circuit board 22; in the second state, the electric contact needle is separated from the contact point, and the sound-emitting device 30 is not powered; wherein, in the first state and the second state, the sound-emitting device 30 can completely cover the mounting hole 421.

[0073] In this embodiment, the mounting hole 421 is a symmetrical rectangular hole, and the outer contour of the part of the sound-emitting device 30 inserted into the mounting hole 421 is also rectangular, which can adapt to the shape of the mounting hole 421 to ensure good air tightness between the sound-emitting device 30 and the mounting hole 421.

[0074] like Fig. 9 As shown, in addition, two avoidance holes 422 connected to the mounting hole 421 are provided on the bottom surface of the bottom cover 40, and the two avoidance holes 422 are symmetrically arranged on the left and right sides of the mounting hole 421. When the cover 321 is located in the avoidance hole 422 on the left, the sound device 30 is in the first state, and when the cover 321 is located in the avoidance hole 422 on the right, the sound device 30 is in the second state. In both the first state and the second state, the atomization channel 101 cannot take in air from the mounting hole 421.

[0075] In another embodiment, the mounting hole 421 may also be a symmetrical structure such as a circular hole, an elliptical hole or a square hole, and the outer contour of the portion of the sound-emitting device 30 inserted into the mounting hole 421 may also be adapted to a corresponding symmetrical structure. It is understandable that the structure of the sound-emitting device 30 and the structure of the mounting hole 421 may be set as required, as long as the sound-emitting device 30 is inserted into the mounting hole 421 and there are both a first state and a second state, and in both the first state and the second state, the sound-emitting device 30 can completely cover the mounting hole 421.

[0086] In the control circuit of this embodiment, when the microphone TK senses the change of airflow in the air inlet channel, it transmits an input signal in the form of a pulse to the control chip U3. After receiving the input signal, the control chip U3 sends a first output signal and a second output signal respectively. When the gate of the field effect tube Q2 receives the first output signal, the source S and the drain D are driven to be connected, and the heating element can be powered and generate heat. When the sound chip U1 receives the second output signal, the sound chip U1 activates the corresponding program and drives the speaker M1 to simulate the sound of the hookah. In addition, when the speaker is working, it will continuously send a working signal to the sound chip U1. When the sound chip U1 receives the second output signal and the working signal at the same time, it will not reactivate the corresponding program and drive the speaker M1 to start making sound again.

[0087] After the control chip U3 sends the second output signal to the sound chip U1, the control chip U3 starts to calculate the working time of the sound device at the time node of sending the second output signal. When the working time is equal to the preset time, the control chip U3 sends a second termination signal to the control chip U3 to drive the speaker to stop making sounds. At the same time, the first termination signal is sent to the field effect tube Q2 to drive the source S and drain D of the field effect tube Q2 to disconnect and stop the heating element from heating. By setting the preset working time, the working time of the sound component is associated with the working time of the heating element, which can avoid the problems of overheating of the heating element and insufficient oil supply.
