Description

Technical Field

[0001] This utility model relates to electric tobacco pipes, and more particularly to a lid for an electric tobacco pipe. Background Technology

[0002] Hookah is a method of inhaling tobacco products using a special tool called a "hookah," which is filtered through water (or other liquid). Hookahs typically use charcoal for lighting, but the carbon monoxide and large amounts of ash produced during combustion pollute the air and are harmful to health. Furthermore, the carbonization process during charcoal production releases thick, oily fumes, causing significant damage to surrounding plants and people's lives. To overcome these problems, a hookah heating pot can be used, employing an electric heat source to directly heat the tobacco. By controlling the temperature, the effective substances in the tobacco can be incorporated into the gas, while avoiding the production of harmful substances such as carbon monoxide and ash. Heating the tobacco requires mixing with air to form smoke. However, a large temperature difference between the outside air and the inside of the hookah can easily lead to water droplets, unstable temperature fluctuations during heating, and incomplete combustion at the bottom, resulting in waste. The purpose of this invention is to provide a lid for an electric hookah that is highly versatile and has high heating temperature stability. Summary of the Invention

[0003] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a lid for an electric tobacco pipe, the electric tobacco pipe including a body, the upper part of the body having a tobacco chamber with an upper opening, the tobacco chamber containing a tobacco cup heated by a heating element, a lid detachably connected above the tobacco chamber to seal the upper opening of the tobacco chamber, the lid including a hollow lid body, a plurality of heat-conducting fins spaced apart and installed in the hollow lid body, and an inlet on the top surface of the hollow lid body for communicating with the outside and allowing fresh air to enter. The hollow cover has an air inlet on the bottom surface of the sealed tobacco chamber, leading to the tobacco cup. The heat-conducting plate has an air guide hole. The heat-conducting plate, which is installed at intervals, forms an air channel in the hollow cover through the air guide hole. The two ends of the air channel are the air inlet and the air intake hole, respectively. The bottom surface of the hollow cover is heated by the heat-conducting plate through the tobacco chamber and / or the tobacco cup, so that fresh air enters the air channel of the hollow cover, is preheated, and then enters the tobacco cup, where it mixes with the tobacco in the tobacco cup to form smoke for direct or indirect inhalation.

[0004] As an improvement: the aforementioned heat-conducting plates are arranged in a series of parallel grids with spacing within the hollow cover body.

[0005] As an improvement, the air guide holes on adjacent heat-conducting plates inside the hollow cover are moved longitudinally away.

[0006] As an improvement, the air guide holes on the heat-conducting fins inside the hollow cover are staggered in a longitudinal manner.

[0007] As an improvement: the air guide holes on the odd-numbered heat-conducting plates in the hollow cover body are located at the center of the heat-conducting plates, while the air heat conduction holes on the even-numbered heat-conducting plates are located away from the center and close to the edge of the heat-conducting plates.

[0008] As an improvement, the air inlet is located on the bottom surface of the hollow cover sealing the tobacco chamber, corresponding to the position of the tobacco cup.

[0009] As an improvement, the top surface of the upper opening edge of the smoke chamber is a heat-conducting surface that directly contacts or contacts the lower bottom surface of the hollow cover through a heat-conducting ring.

[0010] The beneficial effects of this utility model are as follows: This utility model uses a lid on the kettle body to preheat the incoming fresh air in stages before it enters the tobacco cup. The preheating heat of the lid comes from the tobacco chamber and / or the tobacco cup inside the kettle, meaning the lid itself does not have a heating element, thus not burdening the overall power and circuit layout of the device, and offering strong compatibility and versatility. Furthermore, the lid's multi-layered heat-conducting sheets, designed with intervals, form a staged preheating air channel, resulting in excellent preheating. The air preheated through this channel enters the tobacco cup with a small temperature difference, greatly stabilizing the temperature inside the tobacco cup and reducing fluctuations. This leads to high and stable operating efficiency of the heating element and even the entire device, extending the lifespan of the device, while also providing heat insulation for the tobacco chamber and tobacco cup.

[0011] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. Attached Figure Description

[0017] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, this utility model discloses an embodiment of the lid of an electric tobacco pipe. The electric tobacco pipe includes a water tank 4 for holding liquid and filtering smoke, and a body 1 connected above the water tank 4. The body 1 is equipped with an electronic control component and a power supply for the electronic control component. The upper part of the body 1 has a smoke chamber 11 with an upper opening. The smoke chamber 11 contains a tobacco cup 3 heated by a heating element. The body 1 is also equipped with a smoke guide tube. One end of the smoke guide tube is connected to the tobacco cup 3, and the other end extends through a connector into the water tank 4. The water tank or the surface of the body has a smoke inlet that connects to the water tank 4 via a smoke extraction channel. The tobacco cup is heated under the control of the electronic control component to generate smoke, which is then transported to the water tank for filtration via the smoke guide tube. The filtered smoke is then transmitted to the smoke inlet via the smoke extraction channel. A lid 2 is detachably connected to the top of the tobacco chamber 11, sealing the opening of the chamber. The lid 2 includes a hollow lid body 21 and several spaced heat-conducting plates 22 installed inside the hollow lid body 21. The top surface of the hollow lid body 21 has an air inlet 211 that communicates with the outside and allows fresh air to enter. The bottom surface of the hollow lid body 21 that seals the tobacco chamber 11 has an air inlet 212 leading to the tobacco cup 3. The heat-conducting plates 22 have air guide holes 221. Heat-conducting plates installed at intervals form air channels within the hollow cover 21 via air guide holes 221. The two ends of the air channels correspond to air inlets 211 and air intakes 212, respectively. The lower surface of the hollow cover 21 contacts the heat-conducting plates 22 through the smoke chamber 11 and / or the smoke cup 3, allowing fresh air to enter the air channels of the hollow cover 21, preheat, and then enter the smoke cup, mixing with the tobacco (not shown in the figure) to form smoke for direct or indirect inhalation. To improve the preheating effect, the heat-conducting plates are arranged in a series of parallel, horizontally spaced grids within the hollow cover. The air guide holes 221 on adjacent heat-conducting plates within the hollow cover are longitudinally spaced apart. The air guide holes 221 on the heat-conducting plates within the hollow cover are longitudinally staggered. In the hollow cover body, the air guide holes 221 on the odd-numbered heat-conducting plates are located at the center of the heat-conducting plates, while the air conduction holes on the even-numbered heat-conducting plates are located away from the center and close to the edge of the heat-conducting plates. This allows for a longer air passage, providing excellent heat exchange space and enabling step-by-step preheating. The air inlet 212 is located on the bottom surface of the hollow cover body 21 sealing the smoke chamber cavity 11, corresponding to the position of the tobacco cup, to avoid heat loss. The top surface of the upper opening edge of the smoke chamber cavity is a heat-conducting surface that directly contacts or contacts the bottom surface of the hollow cover body 21 through a heat-conducting ring.

[0018] The above describes the direct heating of the tobacco cup by the electric heating element. For electric tobacco bottles that form an aerosol from the heated tobacco, simply sealing the opening on the tobacco cup, i.e., adding a tobacco cup lid, allows the air inlet 212 of this invention to correspond to the inlet of the air heating channel inside the bottle. That is, the air is preheated by the air channel in the lid and then enters the air heating channel for further formal heating before entering the tobacco cup. This greatly improves the heating efficiency of the heating element, ensures the reliability of the electrical connection, and does not affect the overall size of the machine, avoiding bulkiness and improving the overall aesthetics.

[0019] 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.
