DETAILED DESCRIPTION OF THE EMBODIMENTS

The following provides a detailed description of the present disclosure in conjunction with the accompanying drawings.

As shown in FIGS. 1 to 11, the heating device for electronic hookah of the present disclosure includes a heating head 1 and a heating pot 2, where the heating head 1 is positioned at the upper part of the heating pot 2. This arrangement facilitates to control the heating head 1 over a heating process of the tobacco products inside the heating pot 2.

The heating pot 2 is defined with a cavity 4 for holding tobacco products. The cavity 4 has a dedicated space to place the tobacco products, concentrating the tobacco products for more efficient heating and smoke production.

The heating head 1 is defined with a first air inlet channel 3, which communicates with the cavity 4. The heating head 1 is responsible for heating the air entering the first air inlet channel 3 to form hot air, which is then directed into the cavity 4 to heat the tobacco products and generate smoke. By delivering hot air through the first air inlet channel 3, the tobacco products are efficiently and stably heated, leading to stable smoke production.

A bottom of the heating pot 2 is equipped with an air outlet passage 5, which connects to the hookah bottle. The air outlet passage 5 provides a path for the smoke to exit, making it easier for the smoke to enter the hookah bottle for the smoker to inhale.

During use, a suitable amount of tobacco products is placed in the cavity 4 of the heating pot 2, ensuring the tobacco is distributed relatively evenly to allow adequate heating by the hot air. Simultaneously, the outlet passage 5 at the bottom of the heating pot 2 is securely connected to the hookah bottle to ensure the smooth discharge of smoke.

Once the heating head 1 is activated, it heats the air entering the first air inlet channel 3, raising its temperature to form hot air. Since the first air inlet channel 3 is connected to the cavity 4 inside the heating pot 2, the hot air within the first air inlet channel 3 heats the air inside the cavity 4, causing the tobacco products to produce smoke.

The hot air flowing into the cavity 4 fully contacts the tobacco products, transferring heat to them. As the tobacco products absorb sufficient heat, they begin to undergo pyrolysis and gradually produce smoke. With a continuous flow of hot air, the tobacco products remain heated, and smoke continues to be generated and accumulated in the cavity 4.

When the smoker inhales through a straw of the hookah bottle, the smoke is drawn from the cavity 4 through the outlet passage 5. The discharged smoke is filtered through the liquid inside the hookah bottle, providing the smoker with a smoother, purer smoking experience. Throughout the process, the heating head 1 continues to heat the air entering the first air inlet channel 3, ensuring a stable input of hot air, thereby reducing the temperature differential between the hot air and the heating pot 2.

As shown in FIGS. 1 and 3, the heating head 1 in this embodiment includes a main shell 11 and a heating body 12. the main shell 11 is positioned at the upper part of the heating pot 2, positioning the heating head 1 above the heating pot 2.

The first air inlet channel 3 runs through the main shell 11, with both an intake end and an exhaust end. The first air inlet channel 3 establishes an airflow path, allowing air to flow smoothly into the heating pot 2.

The heating body 12 is fixed to the main shell 11 and positioned at the channel entrance of the first air inlet channel 3 to heat the incoming air and form hot air. By utilizing the heating body 12, the air is heated to create the necessary hot air for heating the tobacco products.

The outlet of the first air inlet channel 3 is communicated with the cavity 4, allowing the hot air to enter the cavity 4, thus heating the tobacco products within the cavity 4.

As shown in FIGS. 4-5, the heating body 12 includes an air inlet cover 121, a heating shell 122, and a heating base 123.

An upper part of the heating shell 122 contains an air inlet chamber 1221, and a lower part contains a heating chamber 1222. A vent hole 1223 is positioned between the air inlet chamber 1221 and the heating chamber 1222. The air inlet chamber 1221 introduces air, and the vent hole 1223 directs the air into the heating chamber 1222, providing a path for air to be heated.

The air inlet cover 121 is positioned above the air inlet chamber 1221 and has an air inlet hole 1224 that communicates to the air inlet chamber 1221. The air inlet hole 1224 is served as the entry point for air into the air inlet chamber 1221, ensuring that air flows smoothly into the heating head 1.

The heating base 123 is positioned at a bottom of the heating chamber 1222, and the heating base 123 is defined with an air outlet hole. In other embodiment, may be the heating base 123 is surrounded by multiple air outlet holes 1230. The heating base 123 heats the air entering the heating chamber 1222, and the air outlet hole 1230 releases hot air, creating the necessary hot air for heating the tobacco products. Both the heating shell 122 and the heating base 123 are made from heat-conductive materials, allowing heat to be transferred efficiently from the heating base 123 to the air in the air inlet chamber 1221 and the heating chamber 1222, enhancing the heating efficiency and effectiveness. These components also radiate heat to the tobacco products in the heating pot 2, stabilizing the production of smoke. Heat-conductive materials can be metals such as copper, aluminum, or stainless steel, or alloys such as aluminum-silicon or copper-aluminum.

The air outlet hole 1230 is communicated with the intake end of the first air inlet channel 3. The hot air used to heat the tobacco products is introduced into the first air inlet channel 3, where it is heated and forms hot air.

The air inlet hole 1224, vent hole 1223, and air outlet hole 1230 are arranged in a staggered manner, extending the airflow path within the heating head 1 to ensure thorough heating of the air. This design improves heating efficiency and reduces the speed at which hot air is expelled from the air inlet chamber 1221 and heating chamber 1222.

As shown in FIG. 4, the heating base 123 contains an accommodating chamber 1231, which houses a first heater 1232. Above the accommodating chamber 1231 is a heat expansion component 1233, located inside the heating chamber 1222.

The accommodating chamber 1231 ensures that the first heater 1232 is installed inside the heating base 123 without direct contact with the air, ensuring the stability of the heating function and preventing external influences on the first heater 1232.

The first heater 1232 generates heat, providing the energy required to heat the air in the heating base 123. The heat expansion component 1233, located inside the heating chamber 1222, distributes the heat generated by the first heater 1232 more evenly throughout the heating chamber 1222, improving heating efficiency and uniformity. Specifically, the heat expansion component 1233 acts as a heat sink, evenly distributing the heat produced by the first heater 1232 within the heating chamber 1222.

The first heater 1232 can be a resistive heater, an electromagnetic induction heater, or an infrared heater, all of which are capable of providing the necessary heat.

As shown in FIG. 4, the main shell 11 includes a heat-resistant outer shell 111, a top cover 112, a heat-insulating sheet 113, and a heat-insulating ring 117.

The heat-resistant outer shell 111 is placed around the outside of the main shell 11, creating a heat-insulating cavity 114 between the heat-resistant outer shell 111 and the main shell 11. This setup effectively reduces the external heat transfer from the main shell 11, preventing rapid heat transmission to the outside.

The top cover 112 is positioned at the top of the heat-resistant outer shell 111 and both the top cover 112 and the heat-resistant outer shell 111 are each equipped with a ventilation hole 115. Each ventilation hole 115 allow air to flow within the insulation cavity 114, reducing the surface temperature of the heat-resistant outer shell 111 and preventing the user from being burned.

As shown in FIG. 6, the heat-insulating sheet 113 is placed between the top cover 112 and the air inlet cover 121. The heat-insulating sheet 113 and the top cover 112 are each defined with an avoidance hole 116 aligned with the air inlet hole 1224. The heat-insulating sheet 113 further enhances the insulation effect and prevents heat exchange between the intake air in the air inlet chamber 1221 and the outside, which could impair the heating effect. The design of the avoidance hole 116 does not hinder the normal flow of air through the air inlet hole 1224 into the air inlet chamber 1221, balancing the insulation and air intake functions.

As shown in FIG. 4, the heat-insulating ring 117 is positioned between the heating shell 122 and the main shell 11, ensuring the stability of the temperature inside the heating shell 122 and reducing heat transfer from the heating shell 122 to the main shell 11.

The heat-insulating sheet 113 and heat-insulating rings 117 are made from heat-insulating materials, such as aerogel mats, aluminosilicate fiber, or ceramic fiber.

As shown in FIGS. 3 and 8-9, the heating pot 2 in this embodiment includes a heat-resistant fixed base 21, a heat transfer pot 22, a second heater 23, and a pot body 24.

The heat-resistant fixed base 21 is equipped with a smoke exhausting section 211 that is connected to the smoke outlet channel 5; the smoke exhausting section 211 provides a primary passage for the smoke to be discharged.

The heat transfer pot 22 is fixed to the heat-resistant fixed base 21, and the heat transfer pot 22 is equipped with a smoke vent hole 221 that communicates with the smoke exhausting section 211. The smoke can flow smoothly between the heat transfer pot 22 and the heat-resistant fixed base 21 through the smoke vent hole 221.

The second heater 23 is positioned on the outer side of the heat transfer pot 22. It uses the principle of heat conduction to transfer heat to the heat transfer pot 22, which in turn heats the pot body 24.

The heat-resistant fixed base 21 is made of heat-resistant silicone material, which isolates the heat of the heat transfer pot 22, second heater 23, and pot body 24, preventing heat transfer and ensuring the temperature inside the heating pot 2 remains stable. The second heater 23 can be a resistive heater, electromagnetic induction heater, or infrared heater, all of which can achieve the heating function.

The pot body 24 has a cavity 4 inside, and the pot body 24 is placed inside the heat transfer pot 22. The pot body 24 has a boss 241, and the boss 241 is provided with a smoke outlet hole 242 that communicates with the smoke vent hole 221. The cavity 4 allows the tobacco products to be placed inside the pot body 24, which efficiently receives heat from the heat transfer pot 22, ensuring even heating of the tobacco products to produce smoke. The smoke outlet hole 242 ensures that smoke can be smoothly discharged from the heating pot 2, preventing smoke from accumulating inside the cavity 4. The boss 241 is positioned higher than a bottom wall of the cavity 4, making it less likely for liquid in the cavity 4 to flow through the smoke outlet hole 242 into the smoke outlet channel 5.

As shown in FIG. 4, a pot lifting gap 25 is provided between the upper edge of the pot body 24 and the heat-resistant fixed base 21 to facilitate the removal of the pot body 24. The pot lifting gap 25 provides operational space, allowing the user to easily reach into the pot lifting gap 25 with their hands or with tools to lift the pot body 24, improving the convenience and user experience when operating the heating device.

As shown in FIGS. 5 and 9, the heating head 1 in this embodiment is equipped with a sealing ring 13, which is in contact with the heat-resistant fixed base 21. When the sealing ring 13 comes into contact with the heat-resistant fixed base 21, it undergoes elastic deformation, filling the gap between the heating head 1 and the heat-resistant fixed base 21. This effectively prevents the heat, smoke, and other substances generated during the heating process from leaking out of the connection between the heating head 1 and the heat-resistant fixed base 21, improving the sealing performance of the heating device, ensuring heating efficiency, and preventing heat loss, which could pose safety risks or affect the surrounding environment.

As shown in FIGS. 8 and 10, the smoke exhausting section 211 of the heat-resistant fixed base 21 is equipped with a smoke exhausting pipe 212, and the smoke exhausting pipe 212 contains the smoke outlet channel 5. The hollow structure of the pipe creates a smoke flow path, allowing the smoke generated during the heating process to flow directionally through the smoke outlet channel 5. This ensures that the smoke is discharged in an orderly manner, preventing it from accumulating inside the device.

The lower part of the smoke exhausting pipe 212 is equipped with a connector 213, which connects to the hookah bottle. The connector 213 facilitates the connection of the smoke exhausting pipe 212 to the hookah bottle, allowing the smoke to smoothly enter the hookah bottle for filtration and other processing, improving the overall convenience and functionality of the heating device.

As shown in FIG. 4, the smoke exhausting section 211 near the smoke vent hole 221 is equipped with an oil storage chamber 214. The oil storage chamber 214 provides space for collecting oil droplets in the smoke.

Inside the oil storage chamber 214, there is an inner shell 215 and an oil baffle tube 216. The inner shell 215 is in contact with the inner wall of the oil storage chamber 214, and the oil baffle tube 216 is movably connected to the inner shell 215. The inner shell 215 enhances the structural stability of the oil storage chamber 214, while the inner shell 215 and the oil baffle tube 216 help block and guide oil droplets. The movable connection between the oil baffle tube 216 and the inner shell 215, as well as the contact between the inner shell 215 and the inner wall of the oil storage chamber 214, makes the installation, removal, and cleaning of the oil baffle tube 216 and the inner shell 215 easier.

The upper part of the oil baffle tube 216 is equipped with a smoke passage groove 217 that connects to the smoke exhausting section 211, and the top of the oil baffle tube 216 is covered with a smoke-blocking cover 218. The smoke passage groove 217 allows smoke to pass through, while oil droplets are blocked and fall into the oil storage chamber 214 due to their own gravity and the obstruction of the oil baffle tube 216.

The smoke-blocking cover 218 can change the flow direction of the smoke entering the oil storage chamber 214 through the smoke vent hole 221, guiding the smoke to flow towards the inner wall of the inner shell 215 and further preventing oil droplets from flowing with the smoke. It also guides the smoke to exit from the smoke passage groove 217.

As shown in FIG. 8, an inner side and an outer side of the heat-resistant fixed base 21 are each provided with a heat-insulating component 219. These insulation components use materials with low thermal conductivity to block heat transfer.

As shown in FIGS. 8-9, the heat-insulating component 219 includes a first insulation body 2191, a second insulation body 2192, and a heat-insulating supporting component 2193.

This facilitates assembly and disassembly while ensuring stable connections between components.

As shown in FIGS. 3 and 8, the smoke exhausting section 211 of this embodiment is provided with a second air inlet channel 6 that communicates with the external environment. This allows external air to enter the smoke exhausting section 211 through the second air inlet channel 6 and mix with the smoke, adjusting the concentration of smoke in the smoke exhausting section 211 to meet different user preferences. The smoke flavor can be adjusted according to user requirements.

As shown in FIG. 2, the second air inlet channel 6 includes a channel entrance. The channel entrance of the second air inlet channel 6 is provided with a sliding groove 61, in which a control block 62 is slidably installed to control the opening and closing of the second air inlet channel 6.

By using the sliding relationship between the sliding groove 61 and the control block 62, the position of the control block 62 within the sliding groove 61 can be adjusted. This allows for precise control over the opening and closing of the second air inlet channel 6 or the degree of opening. When the smoke flavor needs to be adjusted, the passage can be opened; when not needed, the passage can be closed, or the amount of external air entering the smoke exhausting section 211 can be controlled by adjusting the degree of opening of the second air inlet channel 6, enabling the adjustment of the smoke flavor. This provides flexible and convenient operation, offering effective and controllable management of the smoke flavor adjustment function.

As shown in FIG. 3, the second air inlet channel 6 also includes a channel exit. The channel exit of the second air inlet channel 6 is provided with a sealing elastic component 63 that controls the opening and closing of the second air inlet channel 6. Utilizing the inherent elastic properties of the sealing elastic component 63, the sealing state at the channel exit of the second air inlet channel 6 can be maintained without external force due to its elastic restoring force. When an appropriate external force is applied, the sealing elastic component 63 deforms to open the passage. This effectively controls the opening and closing of the second air inlet channel 6, ensuring the passage remains sealed when smoke flavor does not need adjustment and preventing smoke leakage, which could affect the user experience. When flavor adjustment is needed, external force can be applied to open the passage, offering simple operation and stable control over the passage opening and closing.

The sealing elastic component 63 and the second air inlet channel 6 are integrally formed using silicone material. The good elasticity, flexibility, and sealing properties of silicone material, as well as the integral molding process, ensure a tight, gap-free connection between the sealing elastic component 63 and the second air inlet channel 6. This enhances the sealing performance between the sealing elastic component 63 and the second air inlet channel 6, reducing issues such as smoke leakage caused by poor connection. Moreover, the simple structure of the integral molding reduces production costs and complexity, while improving the overall stability and reliability of the product.

As shown in FIGS. 3 and 8, specifically, the smoke exhausting section 211 is provided with a flavor adjustment port 2111 corresponding to the second air inlet channel 6. On the outside of the flavor adjustment port 2111, there is a buffer chamber 2112, and the second air inlet channel 6 communicates with the buffer chamber 2112. The external air can enter the smoke exhausting section 211 through the second air inlet channel 6 via the flavor adjustment port 2111, allowing the user to adjust the concentration of the smoke flavor according to their preferences. The buffer chamber 2112 helps prevent the air or smoke from flowing too rapidly or unstably, making the flavor adjustment process smoother and more even, thus enhancing the user's experience and the effectiveness of the smoke flavor adjustment.
