Description

Technical Field

[0001] The present invention relates to the technical field of electronic cigarettes and hookahs, and in particular to a smoking device that uses an electrically heated cigarette cup to generate smoke. Background Art

[0002] Hookahs are a popular tobacco substitute among some ethnic minorities in my country and the Middle East. They use specialized hookah tobacco materials that are heated to produce smoke, which is then filtered through water for inhalation. Hookahs are the utensils used for this purpose. Existing hookahs typically consist of a pipe, a straw, and a water bottle. The pipe is fitted with a fixed outlet. The pipe can be adapted with various components for outlets in different locations, allowing the device to be used by more than one consumer at a time. Whether or not these hookahs are compatible with e-cigarettes, they are prone to battery drain if not shut down promptly, making them less portable. Even if equipped with a standby mode, heating can only be activated by manually turning on a heating switch on the surface of the pipe. The triggering mode is often too rigid, especially in e-cigarette-compatible electric hookahs. Hookahs typically require fresh air to enter the pipe to generate smoke. However, since fresh air must enter the pipe to generate smoke, the significant temperature difference between the outside air entering the pipe and the pipe itself can lead to unstable temperature fluctuations during use. In particular, the actual temperature inside the pipe often falls below the set temperature during inhalation, affecting the taste. Summary of the Invention

[0003] The object of the present invention is to provide an electric smoking pot, which can effectively ensure that the actual temperature in the tobacco cup is not lower than the set temperature during smoking, and the power consumption is optimized.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions: an electric smoking pot, comprising a pot body with a mouthpiece and a cigarette cup, wherein the pot body is provided with an electronic control component, a power supply for powering the electronic control component, and a flue for guiding the smoke from the cigarette cup to the mouthpiece, the electronic control component comprises a power energy consumption optimization circuit and a heating control circuit, and a pressure sensor electrically connected to the power energy consumption optimization circuit is provided on the pot body away from the cigarette mouthpiece, the pressure sensor serves as a pneumatic switch to transmit a trigger signal to the electronic control component; the power energy consumption optimization circuit controls the power supply to the electronic control component, including power-off state, working state, and standby state. In the working state, the heating control circuit realizes calibration of the electric heating element of the cigarette cup under the power supply condition. The heating power control of the set temperature. After the temperature in the cigarette cup reaches the set temperature, the electronic control component receives the trigger signal of the pneumatic switch, and the heating control circuit controls the electric heating element to perform high-power heating operation per unit time corresponding to the trigger signal, so that the electric heating element heats at a temperature higher than the set temperature at the moment of smoking; if the electric heating element does not work continuously, that is, the heating control circuit is in the off state for more than a first threshold time, the power energy consumption optimization circuit controls the power supply to stop supplying power to the heating control circuit and enters the standby state; if the standby state exceeds the standby threshold time or the power switch on the surface of the shell is manually operated, the power energy consumption optimization circuit enters the power-off state. In the power-off state, the power stops supplying power to the electronic control component, and waits for the power switch on the surface of the shell to be manually operated to restore to the standby state.

[0005] As an improvement: the power supply energy consumption optimization circuit controls the power supply to the electronic control component and also includes a wake-up state, that is, the pneumatic switch is triggered within the standby threshold time to switch the power supply energy consumption optimization circuit from the standby state to the wake-up state. In the wake-up state, the power supply resumes supplying power to the heating control circuit, but the heating control circuit is in the off state, that is, the electric heating element is in the non-working state and is waiting to work. If the wake-up state continues for more than the first threshold time, the energy consumption optimization circuit returns to the standby state; in the standby state, the pneumatic switch transmits a trigger signal to the electronic control component as a wake-up signal.

[0006] As an improvement: in the awake state, the trigger signal transmitted by the air pressure sensor to the electronic control component is a working signal, that is, in the awake state, the electronic control component receives the trigger signal from the air pressure sensor, and the power consumption optimization circuit switches to the working state.

[0007] As an improvement: an air cavity is provided on the kettle body away from the mouthpiece, one end of the air cavity is connected to the outside world, and the other end is connected to the flue, and the air pressure sensor is limitedly set at the external connection port of the air cavity.

[0008] As an improvement: in the working state, every time the pneumatic switch trigger signal is received, the electric heating element adds an overflow current of the set current difference on the basis of the set temperature heating working current to heat the set unit time.

[0009] As an improvement: the kettle body is provided with a detachable kettle lid with a cover for sealing the opening on the kettle body, the kettle lid comprises a hollow lid body and a preheating pipe arranged in the hollow lid body, the tube wall of the preheating pipe is made of heat-conducting material, the preheating pipe is provided with an air inlet hole connected to the outside world for fresh air to enter on the outer surface of the hollow lid body, the two ends of the preheating pipe correspond to the air inlet hole and the air vent respectively, and a air vent leading to the cigarette cup is provided on the center of the lower bottom surface of the hollow lid body, the preheating pipe is connected to the cigarette chamber cavity and / or the cigarette cup through a heat-conducting part at the center of the lower bottom surface of the hollow lid body, and forms an air vent leading to the cigarette cup, and the external fresh air enters the preheating pipe of the hollow lid body and is preheated and then enters the cigarette cup through the air vent, mixes with the tobacco material in the cigarette cup to form smoke for direct or indirect inhalation.

[0010] The beneficial effects of the present invention are as follows: the electronic control component of the electric smoking pot uses an air pressure sensor to monitor the smoking status. When the tobacco cup reaches the set temperature during operation, the electric heating element increases the heating power in real time according to the trigger signal from the air pressure sensor. Specifically, the heating power is increased at the moment of smoking compared to when not smoking, thereby balancing the temperature difference caused by external air entering the tobacco cup during smoking, further improving the smoking experience. Furthermore, a power consumption optimization circuit is used to control the power supply status, effectively optimizing the use of power consumption.

[0016] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4As shown, an embodiment of the electric-heated tobacco pipe of the present invention comprises a pipe body 3 with a mouthpiece 32 and a pipe cup 5, and a lid 2 sealed to the pipe body. The pipe body 3 houses an electronic control assembly, a power supply 4 for powering the electronic control assembly, and a flue that directs smoke from the pipe cup to the mouthpiece. The electronic control assembly includes a power supply energy optimization circuit and a heating control circuit. A pressure sensor 9, electrically connected to the power supply energy optimization circuit, is located on the pipe body, away from the mouthpiece. An air cavity 39 is located on the pipe body, away from the mouthpiece. One end of the air cavity 39 is connected to the outside world, and the other end is connected to the flue. The pressure sensor 9 is positioned at the outside connection opening of the air cavity 39. Positioning the air cavity away from the mouthpiece effectively prevents contamination or blockage of the air cavity through the mouthpiece. The pressure sensor within the air cavity acts as a pneumatic switch, transmitting a trigger signal to the electronic control assembly in real time based on airflow changes during inhalation. The power consumption optimization circuit controls the power supply to the electronic control component, including power outage state, working state, standby state, and awakening state. In the working state, the heating control circuit controls the heating power of the electric heating element of the cigarette cup 5 to the set temperature under power supply. After the temperature in the cigarette cup 5 reaches the set temperature, the electronic control component receives the trigger signal of the pneumatic switch, and the heating control circuit controls the electric heating element to perform high-power heating operation per unit time corresponding to the trigger signal, so that the electric heating element heats at a temperature higher than the set temperature at the moment of smoking; if the electric heating element does not work continuously, that is, the heating control circuit is in the off state for more than a first threshold time, the power consumption optimization circuit controls The power supply stops supplying power to the heating control circuit and enters the standby state, waiting to be awakened; within the standby threshold time, the pneumatic switch is triggered and the power energy consumption optimization circuit switches from the standby state to the awakened state. In the awakened state, the power supply resumes supplying power to the heating control circuit, but the heating control circuit is in the off state, that is, the electric heating element is in the non-working state, waiting to work. If the awakened state lasts for more than the first threshold time, the energy consumption optimization circuit returns to the standby state; the standby state exceeds the standby threshold time or the power switch on the surface of the shell is manually operated, and the power energy consumption optimization circuit enters the power outage state. In the power outage state, the power supply stops supplying power to the electronic control components, and waits for the power switch on the surface of the shell to be manually operated to return to the standby state. In the working state, each time the pneumatic switch trigger signal is received, the electric heating element adds the overflow current of the set current difference on the basis of the set temperature heating working current to heat the set unit time. This unit time setting can be set to between 0.5-2 seconds at the factory to correspond to an inhalation time. This embodiment increases power by increasing the current difference. Of course, the temperature can also be balanced according to the external air inlet rate, that is, the power difference or temperature difference. It is only necessary to increase the instantaneous power to always keep the temperature in the cigarette cup at the set temperature.

[0017] The air pressure legend of this embodiment has different functions in different states according to the trigger signal triggered by inhalation, that is, it not only provides a real-time trigger basis for high-power operation in the working state, but also exists as a control signal for state conversion. In the awake state, the trigger signal sent by the air pressure sensor to the electronic control component is the working signal, that is, in the awake state, the electronic control component receives the trigger signal of the air pressure sensor, and the power consumption optimization circuit switches to the working state. The trigger signal sent by the pneumatic switch to the electronic control component in the standby state is the wake-up signal, The power consumption optimization circuit with wake-up state controls the power supply, effectively optimizing the use of power consumption. The setting of wake-up state and air pressure sensor as wake-up switch is more intelligent and user-friendly, providing the basis for energy consumption and small size for outdoor portable use of the equipment.

[0018] After the temperature inside the cigarette cup 5 reaches the set temperature, the electronic control component receives the trigger signal of the pneumatic switch, and the heating control circuit controls the electric heating element to perform high-power heating operation per unit time corresponding to the trigger signal, so that the electric heating element heats at a temperature higher than the set temperature at the moment of smoking.

[0019] In order to further reduce the fluctuations in the tobacco cup caused by smoking, improve the temperature stability of the tobacco cup, reasonably recover the waste heat, and reduce the heat absorption of the outer shell. The kettle body 3 of this embodiment is provided with a detachable kettle lid 2 with a cover for sealing the opening on the kettle body 3. The kettle lid 2 includes a hollow lid body 21 and a preheating pipe arranged in the hollow lid body. The pipe wall of the preheating pipe is made of heat-conducting material. The preheating pipe is provided with an air inlet 211 on the outer surface of the hollow lid body 21 for communicating with the outside world for allowing fresh air to enter. The two ends of the preheating pipe correspond to the air inlet 211 and the air vent 212 respectively. A air vent 212 leading to the cigarette cup 5 is provided on the center of the lower bottom surface of the hollow lid body 21. The preheating pipe is connected to the cigarette chamber cavity 31 and / or the cigarette cup 5 through the heat-conducting member 6 at the center of the lower bottom surface of the hollow lid body 21, and forms an air vent 212 leading to the cigarette cup 5. The external fresh air enters the preheating pipe of the hollow lid body 21 and is preheated, then enters the cigarette cup through the air vent 212, mixes with the tobacco material in the cigarette cup, and forms smoke for direct or indirect inhalation. The preheating channel of this embodiment is formed by a series of concentrically spaced cylindrical gratings arranged vertically within the hollow cover body, serving as several heat-conducting elements. The upper top wall and lower bottom surface of the hollow cover body 21 are respectively sealed and connected to the series of cylindrical gratings, thereby dividing the central cover body into concentric, layered annular spaces through the series of cylindrical gratings. Adjacent annular spaces are connected by air guide holes 221. The air inlet holes 211 are located on the circumferential sidewalls of the central cover body, and the diameter of the smallest cylindrical grating ring is greater than or equal to the outer diameter of the air vents 212. Because the series of cylindrical gratings are arranged vertically and their lower bases are directly connected to the lower bottom surface of the central cover body, heat exchange is relatively uniform between the cylindrical gratings, avoiding thermal discontinuities and significantly improving preheating efficiency. Of course, the preheating channel can also be formed in other forms, such as parallel, spaced-apart heat conducting plates or coiled tubes.

[0020] By installing a lid on the kettle body, incoming fresh air is preheated before entering the tobacco cup. Heat in the lid's preheating pipe is generated through heat exchange between the tobacco chamber within the kettle body and / or the tobacco cup, or / and heat exchange between rising hot air and a heat-conducting element. The lid itself does not contain a heating element, thus minimizing the overall power consumption and circuit layout. The lid also effectively collects and utilizes residual heat within the kettle body, not only providing insulation but also improving heating efficiency and shortening the time it takes to reach the set temperature. The preheating pipe transfers heat from the kettle body via a heat-conducting element, paving the way for diverse preheating pipe designs within the lid.

[0021] Although the present invention has been disclosed above with reference to specific embodiments, they are not intended to limit the present invention. Any person skilled in the art may make slight changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope of the appended claims.
