DETAILED DESCRIPTION

[0023] See Figure 1-Figure 5 As shown, the technical solution adopted in this specific embodiment is: it includes a kettle body 1 and a water tank 2, the kettle body 1 and the water tank 2 are sealed together, a cigarette pot 3 and a heating cup 4 are arranged on the upper part of the kettle body 1, the cigarette pot 3 is movably arranged in the heating cup 4, and a heating plate 5 is arranged on the outer wall of the heating cup 4. In the traditional heating structure, electric heating wire is usually used for heating, which is prone to uneven heating, slow heating, and poor heat preservation effect. Therefore, in this embodiment, a heating plate is used as a heating device to heat the heating cup, and small holes are provided on the heating plate to increase the heating resistance of the heating plate, so that the heating speed is faster and more uniform. In one embodiment, a ceramic fixing ring (not shown in this embodiment) is further provided outside the heating plate, which increases the connection tightness of the heating plate and achieves a better heat preservation effect.

[0024] An air inlet pipe 6 is provided at the bottom of the heating cup 4 and extends into the water tank 2. A one-way air inlet valve 6-1 is sleeved at the bottom of the air inlet pipe 6. A first hole-blocking ball 7 is provided in the one-way air inlet valve 6-1. In the existing hookah structure, there is generally a lack of a flow limiting structure. When the internal air pressure is high, smoke and water will flow back into the smoke pot, which will not only reduce the temperature of the smoke pot but also affect the quality of the tobacco material. Therefore, a first hole-blocking ball is provided in this embodiment. The first hole-blocking ball is a hollow plastic ball. When no air is inhaled, the air pressure and water will lift the first hole-blocking ball to block the air inlet pipe, thereby effectively preventing smoke and water from flowing back and ensuring the use effect.

[0025] To be more specific, the one-way air inlet valve 6-1 is a hollow tube structure with a plug 6-2 provided at the end. The setting of the plug facilitates the installation of the first hole-blocking ball. The one-way air inlet valve 6-1 is provided with an air inlet hole 6-3 near the end side wall. The air inlet hole is the key structure for realizing the up and down movement of the first hole-blocking ball. When water is injected, the first hole-blocking ball will block the air inlet pipe as the water level rises, and when inhaling, the first hole-blocking ball will be sucked down under the action of negative pressure, and the inhaled smoke will also push the first hole-blocking ball open. When the inhalation stops, the water pushes the first hole-blocking ball back again under the action of air pressure, realizing the one-way air intake effect, thereby blocking the air inlet pipe to prevent smoke and water from flowing back into the heating pot body.

[0026] To be more specific, a stepped air duct is provided in the one-way air inlet valve 6-1, and a limited air duct 6-4 is provided on the lower air duct. The limited air duct 6-4 matches the first hole-blocking ball 7. The limited air duct is a structure that specifically limits the displacement of the first hole-blocking ball, so that the first hole-blocking ball can only move between the plug and the limited air duct.

[0027] To be more specific, an exhaust duct 10 is provided on one side of the top of the water tank 2, and an opening is provided on the upper side wall of the exhaust duct 10 which is connected to the corresponding opening of the kettle body 1, and an exhaust cover 12 is provided at the corresponding opening of the kettle body 1. The exhaust duct 10 is a structure that is wide at the top and narrow at the bottom, and a second hole-blocking ball 11 is provided at the transition point. The second hole-blocking ball is also a hollow plastic ball. The exhaust duct can discharge excess smoke in the water tank in time, and the second hole-blocking ball can block the exhaust duct when inhaling, and there will be no air leakage, thereby ensuring the air pressure in the water tank. When not inhaling, the air pressure in the water tank is higher, and the second hole-blocking ball is lifted up for automatic exhaust to achieve a one-way exhaust effect.

[0028] To be more specific, a smoking pipe mounting seat 13 is provided at a position opposite to the exhaust duct 10 on the top of the water tank 2. The smoking pipe mounting seat 13 is located inside the kettle body 1. The smoking pipe mounting seat is mainly used for installing the smoking pipe, and an air intake duct 13-1 is provided inside the smoking pipe mounting seat 13 and is connected to the water tank 2.

[0029] To be more specific, the outer layer of the heating plate 5 is provided with a thermostat 9, a detachable battery pack 8 is provided at the bottom of the kettle body 1, and a control main board is also provided in the shell body 1. The detachable battery pack 8 and the thermostat 9 are electrically connected to the control main board. It can be understood that function buttons are also provided on the kettle body and are electrically connected to the control main board. In this embodiment, a thermostat is also provided to prevent damage to the equipment when a circuit malfunctions and abnormal heating occurs. When the temperature exceeds the set value, the thermostat sends a control signal to the control main board, thereby stopping heating to protect the equipment.

[0030] To be more specific, a spring 14 is provided at the bottom of the cigarette pot 3 to abut against the pot body 1, and a fixed cover is provided on the cigarette pot 3 to be detachably connected to the pot body 1. Setting the cigarette pot as a movable structure facilitates taking out the cigarette pot for cleaning. When in use, the spring is compressed and the cigarette pot is fixed by the fixed cover. When disassembling, the fixed cover spring is opened and the cigarette pot will pop out, making disassembly more convenient.

[0031] To be more specific, a top cover 17 is provided on the top of the pot body 1, one end of the top cover 17 is hinged to the top of the pot body 1, and a return torsion spring 18 is provided at the hinge position, and a lock hook 17-1 is provided at the front end of the top cover 17. In this embodiment, since the top cover is provided with a return torsion spring, it can automatically pop open when the cover is opened, making it convenient to take out the tobacco pot, and a vent is also provided on the top cover to facilitate air intake.

[0032] To be more specific, a lid-opening button 15 is provided on one side of the top of the kettle body 1, and the lid-opening button 15 is movably connected to the kettle body 1 through a slot, and a lock buckle 15-1 is provided at the position of the lid-opening button 15 corresponding to the lock hook 17-1, and a locking spring 16 is provided in the lid-opening button 15, one end of the locking spring 16 is fixed to the kettle body 1, and the other end is against the lid-opening button 15. In this embodiment, a movable lid-opening button is provided, which can be engaged with the lock hook of the top cover through the locking buckle. Pushing the lid-opening button inward to release the lock hook, the top cover can automatically pop open, and pressing the top cover so that the lock hook and the locking buckle are engaged again can fix the top cover.

[0033] The working principle of the present utility model is as follows: when in use, water can be injected through the smoking pipe mounting seat 13, and then the smoking pipe 19 can be installed. During the water injection process, when the water level exceeds the air inlet 6-3, the first hole-blocking ball 7 floats up to block the limit airway 6-4. At this time, water will no longer enter the air inlet pipe 6. When the power button on the kettle body 1 is pressed, the device is powered on, and the heating plate 5 starts to heat. At this time, it can be used. When inhaling, the smoke enters from the air inlet pipe 6, pushes open the first hole-blocking ball 7, and is discharged from the air inlet 6-3, and then enters the smoking pipe 19 from the air inlet duct 13-1. During the inhalation process, the air pressure in the water tank 2 becomes low, and the second hole-blocking ball 11 is sucked down tightly to block the narrow section of the exhaust duct 10, so that there will be no leakage affecting the inhalation effect. When the inhalation stops, the smoke stays in the water tank 2, the air pressure increases, and the second hole-blocking ball 11 is pushed up. The excess smoke is discharged from the exhaust duct 10 and the exhaust cover 12 to prevent the air pressure in the water tank 2 from being too high.
