Description

Technical Field

[0001] The utility model relates to the technical field of hookah smoking utensils, and specifically to a tobacco cup for an electric water-heating hookah pot. Background Art

[0002] A hookah is a tobacco substitute that uses specialized hookah tobacco material that is heated to produce smoke, which is then filtered through water and inhaled. A hookah is a device used for this purpose. Existing hookahs typically consist of a pipe, a suction pipe, and a water bottle. The pipe is fitted with a fixed outlet, and various components with outlets in different locations are available to accommodate the pipe, allowing the device to be used by more than one consumer at a time. A typical hookah typically includes a bowl, a tray, a pipe, a smoke exhaust, and a smoke bottle. A smoke hose is connected to the exhaust hose, and a mouthpiece is attached to the end of the hose for inhalation. According to the different ways of heating tobacco, they can be divided into electric water hookahs and open flame water hookahs. In open flame water hookahs, tobacco is placed in the pipe head, water is filled in the pipe, and a layer of aluminum foil with holes is covered on the top of the pipe head. Some ignited charcoal is placed on the aluminum foil to heat the tobacco and produce smoke. The smoke then enters the pipe through the pipe and the smoke filtered by water is inhaled through the smoking hose. The air flow path of the smoke between the pipe head and the suction nozzle on the hose is the water hookah pipe. It is often the case that the tobacco on the surface has been completely burned, while the tobacco at the bottom has not yet been ignited, that is, the combustion is incomplete, resulting in waste. In addition, open flame water hookahs are dangerous and the places where they can be used are severely restricted. The electric water smoking pot adopts an electric heating element installed in the pot, which heats the tobacco material in the heating cup to produce smoke. The heating is uniform and not easy to waste. In addition, the heating cup of the conventional electric water smoking pot is integrated with the pot body, that is, the heating cup of the electric water smoking pot is not detachable, which makes it difficult to load the tobacco material, cannot be replaced, and is difficult to clean. In addition, the integrated design makes the overall size of the hookah large and inconvenient to carry. Summary of the Invention

[0019] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 As shown, an embodiment of a tobacco cup for an electric hot water tobacco pot of the present invention includes a water tank 1 for holding liquid filtered smoke, a pot body 3 detachably connected to the water tank 1 via a connector 2, an electronic control component and a power supply 4 for powering the electronic control component are provided in the pot body 3, a tobacco tank cavity 31 connected to the electronic control component is provided at the upper portion of the pot body, and the electronic control component is provided with an electrode connector on the inner wall of the tobacco tank cavity 31, a tobacco cup 5 with a built-in electric heater 54 is detachably connected to the tobacco tank cavity 31, that is, the electric heater is clamped within the tobacco cup body and is not exposed to the outside, so that the surface of the tobacco cup 5 is sealed and washable, a smoke guide 6 is further provided in the pot body 3, one end of the smoke guide 6 is connected to the tobacco cup 5, and the other end extends through the connector into the water tank 1, a smoking port is opened on the surface of the water tank or the pot body and is connected to the water tank 1 via a smoking duct, the tobacco cup is heated under the control of the electronic control component to generate smoke, and the smoke is transported to the water tank for filtration via the smoke guide 6, and the filtered smoke is transported to the smoking port 91 via the smoking duct 9.

[0020] The kettle body 3 includes an upper kettle body with a cigarette chamber cavity 31 and a lower kettle body equipped with electronic components such as electronic control components and a power supply. The cigarette chamber cavity 31 is formed in the upper kettle body by an integrally formed seal 8. The top of the smoke guide pipe 6 passes through the seal at the bottom of the cigarette chamber cavity 31 to form a smoke guide port that is compatible with the cigarette cup and can be connected. In the lower kettle body, there is a mounting plastic part 7 with an I-shaped cross-section below the seal. The mounting plastic part 7 is provided with a center hole channel 71 and a circuit mounting cavity 72 separated from the center hole channel 71 by a wall. The electronic control components and the power supply are installed in the circuit mounting cavity 72. The smoke guide pipe 6 is connected to the water tank 1 below the center hole channel 71. The top of the center hole channel 71 protrudes from the top surface of the mounting plastic part 7 and abuts the bottom of the seal, making the center hole channel 71 independent of the mounting plastic part 7, thereby isolating the center hole channel for smoke transportation from the distribution area of ​​electronic components.

[0021] In this embodiment, the smoke guide tube passes through a central hole channel 71, which has a larger inner diameter than the smoke guide tube, forming a tube-within-a-tube structure. This creates an air passage between the smoke guide tube and the inner wall of the central hole channel, forming a component of the smoke duct. In this embodiment, the smoke outlet is located in the upper body. A smoke exhaust passage is provided within the seal. This exhaust passage connects to the smoke outlet on the upper body surface, with its other end located on the lower surface of the seal, connecting to the central hole channel 71 and away from the smoke guide tube. This tube-within-a-tube structure significantly saves space, and its upright design allows for easy disassembly and storage, with the lower portion of the smoke guide tube designed as a telescopic tube.

[0022] The electric hot water pipe uses a pipe with a central bottom opening for smoke to pass through. The pipe 5 has a built-in electric heater 54. The pipe is an integrated structure comprising an inner shell 51 and an outer shell 52 fixedly sleeved on the inner shell 51 and watertightly connected to the inner shell. A hollow cavity is defined between the inner shell and the outer shell, i.e., a hollow cavity is formed between the outer wall of the inner shell 51 and the inner wall of the outer shell 52. Within the hollow cavity 53, the electric heater 54 rests against the outer wall of the inner shell 51 and is spaced away from the inner wall of the outer shell 52, allowing expansion space within the hollow cavity. The electric heater is enclosed within the pipe body and is not exposed, achieving a three-layered pipe body structure that is sealed and washable. The pipe design with its own electric heater allows for easy replacement. The cigarette cup is generally bowl-shaped, with its inner shell 51 and outer shell 52 each having a body and a bottom. The electric heater 54 is attached to the body of the inner shell 51. Connecting contacts 56 are provided on the outer surface of the bottom of the cigarette cup, electrically connected to the electronic control assembly. The electronic control assembly is movably electrically connected to the connecting contacts via a resilient ejector electrode 32. A water-tight one-way vent is provided on the outer shell. This vent, connected to the hollow cavity, allows for unidirectional exhaust and pressure relief. In this embodiment, the one-way vent is implemented by a silicone plug 9 embedded in the outer shell. A micro-pore (not shown in the image) is centrally located within the hollow cavity, providing a watertight seal at atmospheric pressure. This eliminates the risk of expansion caused by electrical heating causing the hollow cavity 53 to rupture due to compression, significantly extending the life of the cigarette cup and improving its overall integrity. The one-way air outlet of this embodiment is arranged at the bottom of the cigarette cup, away from the electric heating element, and it is also convenient to set a non-closed retaining rib between the cup body and the cup bottom in the hollow cavity to further ensure waterproofness and safety.

[0023] To ensure reliable electrical connection and washability of the cigarette cup, the electronic control assembly includes a temperature sensor with a temperature sensor probe 33. This probe elastically extends out of the cigarette chamber 31 and abuts against the bottom of the cigarette cup housing 52 to sense temperature. To ensure stable connection and accurate temperature sensing, the bottom of the cigarette cup housing 52 in this embodiment is provided with an inner groove 55 that mates with the temperature sensor probe. The inner groove 55 is located away from the connection point. This inwardly recessed design ensures insertion and a limited fit, bringing the temperature sensing point closer to the cigarette material, resulting in more sensitive and accurate temperature transfer.

[0024] 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.
