[0026] Please see Figures 1-6 This utility model discloses an electric heating hookah device, comprising: a lower heating assembly and an upper heating assembly. The lower heating assembly includes a lower housing 10, a heating bowl 20 with a heating cavity installed in the lower cavity of the lower housing 10, and a lower heating unit 50 located in the lower cavity and disposed at the bottom of the heating bowl. The upper heating assembly includes an upper housing 60 and an upper heating unit 120 disposed in the upper cavity of the upper housing 60. The upper heating unit 120 covers the upper end of the heating bowl 20 and, together with the lower heating unit 50, provides heat energy to the heating cavity. The heating cavity is also provided with... The material-carrying basket 30 has its bottom wall spaced apart from the bottom wall of the heating bowl 20. To ensure that the heating bowl 20 transfers sufficient heat upward to the material-carrying basket 30 to heat the heatable material inside, the distance between the bottom wall of the material-carrying basket 30 and the bottom wall of the heating bowl 20 is less than or equal to 20 mm. The material-carrying basket 30 is used to hold the heatable material. When the electric heating hookah device heats the heatable material, it generates a large amount of smoke. The smoke is then passed through the aqueous solution in the hookah for the consumer to inhale, making the smoke in the mouth more mellow and popular with consumers.

[0027] In one embodiment, the lower heating unit 50 may also be spaced apart from the bottom wall of the heating bowl 20, and in order to ensure that the lower heating unit 50 can provide sufficient heat to the heating bowl 20, the distance between the lower heating unit 50 and the bottom wall of the heating bowl 20 needs to be less than or equal to 20 mm.

[0028] Furthermore, the upper heating unit 120 is disposed at the upper end of the lower housing 10, and the lower housing 10, the lower heating unit 50, and the upper heating unit 120 together form the heating cavity.

[0029] In this embodiment, the structure of the upper heating unit 120 is the same as that of the lower heating unit 50, and the lower heating unit 50 and the upper heating unit 120 are arranged in a mirror image of each other on the horizontal plane at the upper and lower ends of the heating bowl 20.

[0030] Please see Figure 5 and Figure 6The structure of the lower heating unit 50 will be described in detail below. The lower heating unit 50 includes a lower heating plate 51 and a resistor circuit 52 printed on one surface of the lower heating plate 51. The resistor circuit 52 is C-shaped and arranged on the lower heating plate 51, and its end is provided with a conductive contact 521. In this embodiment, the conductive contact 521 is arranged in a ring to increase the contact area with the power terminal 200, so as to ensure a more stable electrical connection with the power terminal 200. In use, power is supplied to the resistor circuit 52 through the power terminal 200. The resistor circuit 52 converts electrical energy into heat energy and releases it through the lower heating plate 51 to heat the heatable material in the heating chamber and complete the atomization of the heatable material.

[0031] In this embodiment, the lower heating plate 51 of the lower heating unit 50 is attached to the bottom of the heating bowl 20, and the heat generated by the resistor circuit 52 on the heating plate 51 heats the heating cavity of the heating bowl 20. In other embodiments, when the heating bowl 20 is made of a thick film material, the lower heating unit 50 can also be formed by printing the resistor circuit 52 on the bottom of the heating bowl 20. The other structures are the same as in this embodiment, which can save the lower heating plate 51. Therefore, the structure is not particularly limited as long as the function of heating the heating cavity of the heating bowl 20 is realized by the heat generated by the resistor circuit 52.

[0032] Furthermore, the lower heating unit 50 also includes a fixing post 53 welded to the lower heating plate 51, a conductive pad 54 located between the power terminal 200 and the conductive contact 521 and electrically connecting the conductive contact 521 and the power terminal 200, and a pressing block 55 pressed against the upper end of the power terminal 200. The welding post 53 is located in the middle of the annular conductive contact 521 and has a thread at its upper end. When the pressing block 55, the power terminal 200 and the conductive pad 54 are stacked sequentially above the conductive contact 521, the fixing nut 56 is threadedly connected to the fixing post 53 so that the pressing block 55 presses down on the power terminal 200 and keeps the power terminal 200 electrically connected to the conductive contact 521 of the resistor circuit 52 through the conductive pad 54.

[0033] In this embodiment, the resistor circuit 52 of the lower heating unit 50 is located on the side away from the heating bowl 20, so as to facilitate the connection of the power terminal 200 to the lower heating unit 50.

[0034] Since the structure of the upper heating unit 120 is the same as that of the lower heating unit 50, the structure of the upper heating unit 120 will not be described again.

[0035] Please see Figure 2 and Figure 3 In this embodiment, the lower heating unit 50 is spaced apart from the bottom wall of the lower housing 10, and the upper heating unit 120 is spaced apart from the top wall of the upper housing 60. This serves two purposes: firstly, to provide space for the power supply pressing structure, and secondly, to provide heat insulation space, thus preventing the heat generated by the lower heating unit 50 from being transferred to the lower housing 10 and the heat generated by the upper heating unit 120 from being transferred to the upper housing 60, thereby avoiding heat waste.

[0036] Please see Figure 3 and Figure 7 The lower housing 10 has an air vent 11 at its bottom, and an air vent pipe 80 extending toward the lower heating unit 50 is provided inside the air vent 11. The end of the air vent pipe 80 is connected to the lower clearance hole 57 of the lower heating unit 50. Furthermore, the end of the air vent pipe 80 passes through the lower clearance hole 57 and is connected to the vent hole 22 at the bottom of the heating bowl 20. The upper housing 60 has an air inlet 61 at its top, and an air inlet pipe 130 extending toward the upper heating unit 120 is provided inside the air inlet 61. The end of the air inlet pipe 130 is connected to the upper clearance hole 121 of the upper heating unit 120.

[0037] Please continue reading. Figure 3 The lower heating unit 50, the air outlet pipe 80, and the lower housing 10 together form a lower sealed space; the upper heating unit 120, the air inlet pipe 130, and the upper housing 60 together form an upper sealed space. The sealing arrangement of the lower and upper sealed spaces prevents smoke particles generated by the heating of the heatable material from adhering to the heat generated by the resistive circuit 52 and reduces the need for cleaning smoke particles adhering to the resistive circuit 52 after use of the electric heating water fume device.

[0038] Please continue reading. Figure 3The bottom wall of the heating bowl 20 is provided with a vent pipe 21 extending towards the material basket, corresponding to the vent pipe 80. The vent pipe 21 is connected to the vent pipe 80. More specifically, the vent hole 22 is located in the hollow position of the vent pipe 21, and the end of the vent pipe 80 is sealed and connected to the vent hole 22. Further, the material basket 30 is provided with a protrusion 31 corresponding to the vent pipe 21, and the end of the vent pipe 21 is spaced apart from the protrusion 31 to allow the smoke generated after the heatable material is heated to flow from the vent pipe 21 to the vent pipe 80. A first connecting pipe 100 is connected to the air outlet 11 of the lower housing 10. One end of the first connecting pipe 100 is connected to the air outlet pipe 80, and the other end of the first connecting pipe 100 is connected to a second connecting pipe 90. The second connecting pipe 90 is funnel-shaped with a larger opening diameter and is connected to the hookah. Therefore, the smoke generated after the heated material is heated flows through the air duct 21 to the air outlet pipe 80, and then through the first connecting pipe 100 and the second connecting pipe 90. Finally, it enters the liquid in the hookah through the second connecting pipe 90 and reaches the consumer's mouth. The smoke has a smoother taste after being mixed with the liquid in the hookah, which is an important reason why consumers like it.

[0039] Please see Figure 4 The bottom wall of the material basket 30 has through holes 32, which are arranged annularly around the protrusion 31. The through holes 32 allow the smoke generated after heating the heatable material to flow into the vent holes 22 of the vent pipe 21. The upper end of the material basket 30 overlaps and is sealed to the upper end of the heating bowl 20 to prevent the smoke generated after heating the material from flowing through the through holes 32 towards the upper heating assembly. More specifically, the sidewalls of the material basket 30 and the heating bowl 20 are spaced apart, with the distance between them being less than or equal to 20 mm. This ensures that the heating bowl 20 transfers sufficient heat to the material basket 30 to heat the heatable material inside.

[0040] It should be noted that in this invention, the distance between the bottom wall of the material basket 30 and the bottom wall of the heating bowl 20, the distance between the lower heating unit 50 and the bottom wall of the heating bowl 20, and the distance between the side wall of the material basket 30 and the side wall of the heating bowl 20 are all required to be less than or equal to 20 mm. The purpose is that, based on experimental data, when the distance is greater than 20 mm, the heat transfer will decrease exponentially, making it impossible to guarantee sufficient heat transfer, thus failing to heat the heatable material in the material basket 30. Therefore, ensuring that the distance is less than or equal to 20 mm is necessary to achieve the heat transfer requirements of this invention.

[0041] Furthermore, in this embodiment, the distance between the side wall of the material-carrying basket 30 and the side wall of the heating bowl 20, as well as the distance between the lower heating unit 50 and the bottom wall of the heating bowl 20, can all be set to 0, i.e., they are in close contact with each other; while the distance between the bottom wall of the material-carrying basket 30 and the bottom wall of the heating bowl 20 is required to be greater than 0, i.e., to maintain a certain gap so that the smoke generated by the heating bowl 20 heating the heatable material can enter the ventilation pipe 21 through the gap, and finally flow out from the exhaust pipe 80 for consumers to enjoy.

[0042] Please see Figures 1-4 The electric heating hookah device further includes a lower flange ring 40 disposed around the lower housing 10 and an upper flange ring 70 disposed around the upper housing 60. The lower flange ring 40 is used to connect with the lower protective cover of the electric heating hookah device, and the upper flange ring 70 is used to connect with the upper protective cover of the electric heating hookah device. By setting the lower flange ring 40 and the upper flange ring 70, the heat generated by the lower heating component and the upper heating component can be effectively prevented from being transferred to the lower protective cover and the upper protective cover, thus avoiding burns to consumers when using the electric heating hookah device due to touching the lower protective cover and / or the upper protective cover. In this embodiment, the lower heating plate 51 and the upper heating plate are thick film heating plates with an operating temperature of up to 400℃~500℃. Therefore, preventing consumers from being burned by the lower protective cover and / or the upper protective cover is a relatively important task in the design of the electric heating hookah device.

[0043] Please see Figure 1 and Figure 4The electric heating water fume device further includes a hinge assembly 110 connected to the lower heating assembly and the upper heating assembly. The hinge assembly 110 includes a lower connector 111 and an upper connector 112. The lower connector 111 is connected to the lower housing 10, and the upper connector 112 is connected to the upper housing 60. The lower connector 111 has a rotating shaft facing the upper connector 112, and the upper connector 112 has a shaft hole corresponding to the rotating shaft. The upper connector 112 can move up and down along the rotating shaft and can rotate around the rotating shaft. A limiting member 113 is installed at the upper end of the rotating shaft. The limiting member 113 is used to limit the stroke of the upper connector 112 to prevent the upper connector 112 from disengaging from the lower connector 111. The upper connector 112 and the lower connector 111 move in coordination to open or close the lower heating unit and the upper heating unit. In the open state, the heating material is added and cleaned after use. In the closed state, the electric heating hookah device is used by the consumer.

[0044] Furthermore, the lower connector 111 is connected to the lower flange ring 40 fixed to the periphery of the lower housing 10, and the upper connector 112 is connected to the upper flange ring 70 fixed to the periphery of the upper housing 60.

[0045] The electric heating hookah device provided by this utility model, by setting the upper heating unit 120 and the lower heating unit 50 at the upper and lower ends of the heating bowl 20, enables the electric heating hookah device of this utility model to heat the heatable material at both ends simultaneously, which greatly improves the heating efficiency. In addition, the electric heating hookah device adopts the electric heating principle, which can effectively avoid the generation of toxic gases during the heating process, and is very popular among consumers.

[0046] Furthermore, a material-carrying basket 30 is provided inside the heating bowl 20. The smoke generated by heating is transported to the aqueous solution of the external hookah through the through hole 32 at the bottom of the material-carrying basket 30, making the smoke inhaled by the consumer more gentle. In addition, an air outlet pipe 80 is connected between the lower heating unit 50 and the lower housing 10, and an air inlet pipe 130 is connected between the upper heating unit 120 and the upper housing 60, maintaining a continuous smoking channel from the air inlet pipe 130, the heating chamber, the through hole 32 to the air outlet pipe 80, so that the consumer can smoothly mix the smoke generated by the heated material with the air entering through the air inlet pipe 130 and then inhale it through the air outlet pipe 80 to achieve the pleasure of smoking.

[0047] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
