Description

Technical Field

[0001] This utility model relates to the field of electronic cigarettes and hookah technology, and in particular to a smoking device that uses an electrically heated smoking cup to generate smoke. Background Technology

[0002] Hookah is a tobacco substitute popular among some ethnic minorities in my country and in the Middle East. It uses special hookah tobacco that is heated to produce smoke, which is then filtered through water before inhalation. A hookah is the device used for smoking hookah. Existing hookahs generally include a pipe, a straw, and a water bottle. The pipe has a fixed outlet, and various parts with different outlet positions can be fitted to the pipe, allowing the device to be used by multiple consumers at once. However, most hookahs, regardless of whether they are compatible with e-cigarettes, are prone to battery drain if not switched off promptly, hindering portability. Even with a standby mode, the heating mode can only be activated manually by turning on the heating switch on the surface of the hookah. The triggering mode is too simplistic and inflexible, especially for electric hookahs compatible with e-cigarettes. Because e-cigarettes and hookahs produce smoke differently—hookahs, whether heated by electricity or flame, continuously produce smoke, while e-cigarettes produce smoke by inhaling through the mouthpiece, stopping atomization when not inhaling—they atomize in real-time. Therefore, current hookah and e-cigarette integrated devices typically use two separate units housed within a single casing. To facilitate airflow, the e-cigarette's atomizing device is usually positioned near or directly on the mouthpiece. However, this design is inconvenient due to space constraints, making disassembly and replacement difficult, cleaning challenging, and potentially affecting the taste. Furthermore, this structure prevents the mouthpiece from closing completely, leaving it constantly open. In hookah mode, this can cause liquid to flow back into the air passage, blocking it. If electronic components are present in the air passage, this can lead to circuit malfunctions, damaging the entire electronic control system and shortening the device's lifespan. Summary of the Invention

[0003] The purpose of this invention is to provide an electric tobacco pipe with a control circuit that has a wake-up state, thereby optimizing power consumption.

[0004] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: an electric tobacco bottle, including a bottle body with a mouthpiece and a tobacco cup, wherein the bottle body is provided with an electronic control component, a power supply for the electronic control component, and a flue for guiding smoke from the tobacco cup to the mouthpiece. The electronic control component includes a power consumption optimization circuit and a heating control circuit. The power consumption optimization circuit controls the power supply to the electronic control component, including a power-off state, a working state, a standby state, and a wake-up state. In the working state, the heating control circuit controls the heating power of the electric heating element in the tobacco cup when the power supply is on. If the electric heating element is not working for a period of time, i.e., the heating control circuit is in a closed state for a period of time, the power consumption optimization circuit controls the power supply to stop supplying power to the heating control circuit, and the device enters a standby state, waiting to be woken up. Within the standby threshold time, the power consumption optimization circuit is activated to switch from standby to wake-up. In wake-up, the power supply resumes to the heating control circuit, but the heating control circuit is off, meaning the electric heating element is not working and awaits activation. If the wake-up state continues for more than the first threshold time, the power consumption optimization circuit returns to standby. If the standby state exceeds the standby threshold time without activation or the power switch on the housing surface is manually operated, the power consumption optimization circuit enters a power-off state. In the power-off state, the power supply stops supplying the electronic control components. The standby state is restored by manually operating the power switch on the housing surface. A pressure sensor electrically connected to the power consumption optimization circuit is located on the kettle body away from the mouthpiece. The pressure sensor acts as a wake-up switch, sending a wake-up signal to the electronic control components.

[0005] As an improvement: the pressure sensor also acts as a heating switch to send working signals to the electronic control component in the wake-up state. That is, in the wake-up state, the electronic control component receives the trigger signal from the pressure sensor again or multiple times, and the power consumption optimization circuit switches to the working state.

[0006] 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 and the other end is connected to the flue, and the air pressure sensor is limited at the external connection port of the air cavity.

[0007] As an improvement: the air cavity includes, from the outside to the inside, a conical external connecting section equipped with a pressure sensor, an intermediate cavity section, and a connecting section connected to the flue with an inner diameter smaller than the intermediate cavity section. The intermediate cavity section is provided with a rolling ball that can roll within the intermediate cavity section. When the ball rolls to the position where the external connecting section and the intermediate cavity section connect, it seals the air cavity. A negative pressure anti-sealing structure is provided at the connection point between the connecting section and the intermediate cavity section to prevent the rolling ball from blocking the connecting section.

[0008] As an improvement: the negative pressure anti-sealing structure consists of several spacer ribs distributed on the connecting section and the connecting end of the intermediate cavity section, with anti-sealing ventilation grooves formed between the spacer ribs, and the free ends of the spacer ribs forming a resisting surface that can abut against the rolling balls to prevent the rolling balls from entering the connecting section.

[0009] The beneficial effects of this utility model are: the electronic control component of this electric tobacco bottle adopts a power consumption optimization circuit with a wake-up state to control the power supply, which effectively optimizes the use of power consumption. The wake-up state and the setting of the air pressure sensor as a wake-up switch are more intelligent and user-friendly, providing a basis for energy consumption and small size for the portable use of the device outdoors.

[0010] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. Attached Figure Description

[0014] like Figure 1 , Figure 2 , Figure 3 As shown, one embodiment of the electric smoking bottle of this utility model includes a bottle body 3 with a mouthpiece 32 and a smoking cup 5. The bottle body 3 contains an electronic control component, a power supply 4 for powering the electronic control component, and a flue 6 for guiding smoke from the smoking cup to the mouthpiece. The bottle body has a smoking cup cavity 31 with a detachable electrical connection to the smoking cup 5. The electronic control component has an electrode connector on the inner wall of the smoking cup cavity 31. The smoking cup 5 with a built-in electric heating element is detachably connected to the smoking cup cavity 31; that is, the electric heating element is clamped inside the smoking cup and not exposed, achieving a sealed and washable surface for the smoking cup 5. In this embodiment, the shell has a water tank 1 at the bottom for holding liquid-filtered smoke in hookah mode. A flue 6 is formed inside the shell by a smoke guide pipe, a smoke outlet 2, and a mouthpiece 32. One end of the smoke guide pipe connects to the smoking cup 5, and the other end extends into the water tank 1. The water tank and the mouthpiece are connected through the smoke outlet 2. In hookah mode, the hookah cup is heated under the control of the electronic control components to generate smoke, which is then transported to the water tank for filtration through the smoke guide tube. The smoke, after being filtered by the liquid, is then transmitted to the mouthpiece through the smoke outlet 2. In electronic cigarette mode, the water tank 1 is empty and does not contain any liquid, meaning that there is a direct flow of smoke between the end of the smoke guide tube and the smoke outlet 2.

[0015] The electronic control component includes a power consumption optimization circuit and a heating control circuit. The power consumption optimization circuit controls the power supply to the electronic control component, including power-off state, working state, standby state, and wake-up state. In the working state, the heating control circuit controls the heating power of the electric heating element of the cigarette cup 5 when the power supply is on. If the electric heating element remains inactive (i.e., 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 to stop supplying power to the heating control circuit, entering a standby state, awaiting wake-up. Within the standby threshold time, the wake-up switch is triggered, and the power consumption optimization circuit switches from the standby state to the wake-up state. In the wake-up state, the power supply resumes operation. The heating control circuit is powered on, but it remains off, meaning the electric heating element is not in operation and is awaiting activation. If the activation state persists for more than a first threshold time, the power optimization circuit returns to standby mode. If the standby state exceeds the standby threshold time without activation or the power switch on the housing surface is manually operated, the power optimization circuit enters a power-off state. In this state, the power supply to the electronic control components is stopped, and the standby state is restored only after the power switch on the housing surface is manually operated. A pressure sensor 9, electrically connected to the power optimization circuit, is located on the kettle body away from the mouthpiece. This pressure sensor acts as a wake-up switch, sending a wake-up signal to the electronic control components. The first threshold time and the standby threshold time can be set by the program as needed. In the activation state, the pressure sensor also acts as a heating switch, sending a working signal to the electronic control components. That is, in the activation state, if the electronic control components receive the trigger signal from the pressure sensor again or multiple times, the power optimization circuit switches to the working state.

[0016] An air cavity 39 is provided on the body of the bottle, away from the mouthpiece. One end of the air cavity 39 is connected to the outside, and the other end is connected to the middle of the smoke guide tube 6 of the flue. A pressure sensor 9, electrically connected to the control circuit, is positioned at the external connection port of the air cavity 39. To make the structure more reasonable, easier to manufacture, and reduce costs, in this embodiment, a smoke chamber 31 is formed inside the bottle by an integrally molded sealing member 8. The smoke guide tube 6 is connected to the functional smoke cup 5 through the sealing member 8, and the electronic cigarette air cavity 39 is directly disposed on the sealing member 8.

[0017] The air cavity, located away from the mouthpiece, effectively prevents contamination or blockage of the air cavity by the mouthpiece. Furthermore, the air cavity is connected to the beginning of the smoke channel within the housing, i.e., the smoke passage. In e-cigarette mode, because the smoke passage within the housing is a straight-through type, the air pressure sensor in the air cavity sends multiple trigger signals to the electronic control components based on changes in air pressure or airflow in the smoke passage, thus enabling users to inhale and activate the device instantly in e-cigarette mode. In hookah mode, the smoke within the housing is transported to the water tank for filtration through the smoke guide tube. The smoke filtered by the liquid in the water tank is then transmitted to the mouthpiece for inhalation through the smoke outlet. In other words, the smoke passage within the housing is not a straight-through type due to the separation by the liquid in the water tank, resulting in stable air pressure or airflow within the air cavity. The control circuit continuously supplies power to the electric heating element for heating.

[0018] In this embodiment, the air passage 39 includes, from the outside in, a conical external connecting section 391 on which a pressure sensor 9 is installed, an intermediate cavity section 392, and a connecting section 393 connected to the smoke guide pipe with an inner diameter smaller than the intermediate cavity section. A rolling ball 38 is provided within the intermediate cavity section 392. The rolling ball 38 rolls to the point where it connects the external connecting section 391 and the intermediate cavity section 392, sealing the air passage 39. A negative pressure anti-sealing structure 395 is provided at the connection point between the connecting section 393 and the intermediate cavity section 392 to prevent the rolling ball 38 from blocking the connecting section. The conical external connecting section 391 prevents excessive air from entering, ensuring the sensitivity of the pressure sensor 9.

[0019] In this embodiment, the negative pressure anti-sealing structure 395 consists of several spacer ribs distributed on the connecting section 393 and the connecting end of the intermediate cavity section 392. The anti-sealing ventilation grooves are formed between the several spacer ribs, and the free ends of the several spacer ribs form a resisting surface that can abut against the ball 38 to prevent the ball 38 from entering the connecting section 391.

[0020] Although the present invention has been disclosed above with specific embodiments, it is not intended to limit the present invention. Any person skilled in the art may make some modifications and refinements 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.
