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] Hookahs filter tobacco through water (or other liquid) before smoking. They are typically lit with charcoal, but the combustion of charcoal produces carbon monoxide and a large amount of ash, polluting the air and posing a health hazard when inhaled. Furthermore, the carbonization process during charcoal production releases thick, oily fumes, significantly harming surrounding plants and people. To overcome these problems, a hookah heating pot can be used. This pot uses an electric heat source to directly heat the tobacco, allowing the effective substances in the tobacco to enter the gas while avoiding the production of harmful substances like 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 cause unstable temperature fluctuations during use, especially during smoking. This often results in the surface tobacco being completely burned while the bottom remains uncooked, leading to incomplete combustion and waste. Summary of the Invention

[0003] The purpose of this invention is to provide a lid for an electric tobacco bottle that is versatile, temperature controllable, and highly stable.

[0004] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a lid for an electric tobacco bottle, the electric tobacco bottle 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 to the upper part of the tobacco chamber to seal the upper opening of the tobacco chamber, the lid including a hollow lid body and a preheating pipe disposed within the hollow lid body, the wall of the preheating pipe being made of a heat-conducting material, the preheating pipe being located on the outer surface of the hollow lid body. The cover has an air inlet that connects to the outside and allows fresh air to enter. The two ends of the preheating pipe are respectively the air inlet and the vent. The center of the bottom surface of the hollow cover has a vent leading to the tobacco cup. The preheating pipe is connected to the tobacco chamber and / or the tobacco cup through a heat-conducting component at the center of the bottom surface of the hollow cover, forming a vent leading to the tobacco cup. Fresh air enters the preheating pipe of the hollow cover, is preheated, and then enters the tobacco cup through the vent, where it mixes with the tobacco in the tobacco cup to form smoke for direct or indirect inhalation.

[0005] As an improvement, the preheating pipe is coiled in a curved shape within the hollow cover body.

[0006] As an improvement: the air inlet of the preheating pipe is located on the upper part of the top cover or the upper part of the peripheral wall of the hollow cover, that is, the preheating pipe is formed by a circular spiral from top to bottom inside the hollow cover.

[0007] As an improvement: the heat-conducting component is axially upright and its top extends into the interior of the hollow cover, and the preheating pipe is coiled around the outer periphery of the heat-conducting component.

[0008] As an improvement, the hollow cover is wrapped with a heat insulation sleeve that does not seal the air inlet.

[0009] 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 before it enters the tobacco cup. The preheating heat from the lid's preheating pipe comes from heat exchange within the tobacco chamber and / or the tobacco cup, or / and from heat exchange between the rising hot air and the heat-conducting element. The lid itself does not contain a heating element, thus not burdening the overall power and circuit layout of the machine. The lid can also effectively collect and utilize residual heat within the kettle, not only providing insulation but also improving heating efficiency and shortening the time to reach the set temperature. The preheating pipe transfers heat from within the kettle via the heat-conducting element, laying the foundation for diverse designs of the preheating pipe within the lid and facilitating manufacturing.

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

[0013] Figure 3 This is a schematic diagram of the second embodiment of the lid for an electric tobacco bottle according to the present invention. Detailed Implementation

[0014] like Figure 1 , Figure 2As shown, the first embodiment of the present invention is used for the lid of an electric tobacco bottle. The electric tobacco bottle includes a body 1, and a tobacco chamber 11 with an upper opening at the top of the body 1. The tobacco chamber 11 contains a tobacco cup 3 heated by a heating element. A lid 2 is detachably connected to the top of the tobacco chamber 11 to seal the upper opening of the tobacco chamber. The lid 2 includes a hollow lid body 21 and a preheating pipe disposed within the hollow lid body. The wall of the preheating pipe is made of a heat-conducting material. The preheating pipe has an opening on the outer surface of the hollow lid body 21 that connects to the outside to allow fresh air to enter. The preheating pipe has an air inlet 211, and its two ends are respectively an air inlet 211 and a vent 212. A vent 212 leading to the tobacco cup 3 is opened at the center of the lower bottom surface of the hollow cover 21. The preheating pipe is connected to the tobacco chamber 11 and / or the tobacco cup 3 via a heat-conducting component 5 at the center of the lower bottom surface of the hollow cover 21, forming a vent 212 leading to the tobacco cup 3. Fresh air enters the preheating pipe of the hollow cover 21, is preheated, and then enters the tobacco cup through the vent 212, mixing with the tobacco in the tobacco cup to form smoke for direct or indirect inhalation. To better extend the length of the preheating pipe and facilitate processing, the preheating pipe is coiled in a curved shape within the hollow cover. In terms of production, the preheating pipe can be processed independently and then assembled into the hollow cover. The air inlet 211 of the preheating pipe is located on the upper part of the top cover or the upper part of the peripheral wall of the hollow cover, that is, the preheating pipe is formed by rotating in a circle from top to bottom inside the hollow cover.

[0015] like Figure 3 As shown, the second embodiment of this utility model is based on the first embodiment, which improves the heat conduction speed and heat conduction uniformity. The heat conduction element 5 is axially upright and its top extends into the interior of the hollow cover. The preheating pipe is coiled around the outer periphery of the heat conduction element.

[0016] To prevent heat loss and improve insulation, the outer periphery of the hollow cover 21 may also be covered with a heat insulation sleeve (not shown in the figure) that does not seal the air inlet 211.

[0017] 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.
