[0052] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of this utility model. Based on the description of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0053] The terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the product of this utility model is usually placed in when in use. They are only for the convenience of description and simplification, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0054] The terms “include,” “comprising,” or any other variation thereof are intended to cover non-exclusive inclusion, which includes not only the elements listed but also other elements not expressly listed.

[0055] Please see Figures 1-10 This utility model discloses a hookah device, including a lower heating assembly 100 and an upper heating assembly 200 that cooperate with each other. The lower heating assembly 100 includes a lower heating bowl 105 with a lower heating cavity 1052 and a lower heating unit 106 disposed at the bottom of the lower heating bowl 105. The upper heating assembly 200 includes an upper heating bowl 205 with an upper heating cavity 2052 and an upper heating unit 206 disposed at the top of the upper heating bowl 205. The lower heating bowl 105 and the upper heating bowl 205 together form a heating space. The lower heating unit 105... The lower heating bowl 105 and the upper heating bowl 206 are used to provide the heat energy required for heating the heating space. When the water pipe device is in use, the lower heating bowl 105 and the upper heating bowl 205 cover each other to form the heating space. The heatable material is located in the heating space. The lower heating unit 106 and the upper heating unit 206 heat the material simultaneously and transfer the heat energy to the heating space, which greatly shortens the time for the heatable material to enter the atomization state. Moreover, the sealed heating space can also ensure that heat is lost through outflow, thereby greatly improving the heating efficiency.

[0056] In this embodiment, tobacco paste can be used as the heatable material. That is, the tobacco paste is heated and melted to produce smoke, which is then inhaled by the consumer through the hookah. In other embodiments, the heatable material can also be tobacco leaves, tobacco shreds, or other heatable tobacco materials, which are not particularly limited here.

[0057] Please see Figures 11-21 The lower heating assembly also includes a material basket 107 located within the lower heating cavity 1052 of the lower heating bowl 105.

The material basket 107 is provided with a through hole 1071 and the through hole 1071 is located at least on the bottom wall of the material basket 107. The through holes 1071 located on the bottom wall of the material basket 107 are arranged in a ring around the boss 1073. In this embodiment, the through hole 1071 is only provided on the bottom wall of the material basket 107. In other embodiments, the through hole 1071 may also be located on the side wall of the material basket 107, and it is necessary to keep the side wall of the material basket 107 and the side wall of the heating bowl 105 spaced apart. Therefore, the location of the through hole 1071 is not particularly limited.

The lower resistance circuit 1062 is electrically connected to an external conductive terminal 1000, and the external conductive terminal 1000 provides electrical energy to the lower resistance circuit 1062. The electrical energy is then converted into heat energy by the lower resistance circuit 1062 and provided to the lower heating bowl 105, thereby heating the heatable material in the lower heating cavity 1052 of the lower heating bowl 105. More specifically, the heatable material is placed in the material basket 107 within the lower heating chamber 1052, and the smoke generated after the heatable material is heated by the lower heating unit 106 is discharged from the through hole 1071 through the air outlet 1051 and the air outlet pipe assembly.

After the upper housing 201 and the lower housing 101 are separated to a certain distance, the upper connecting member 302 is rotated along the axis of the connecting shaft 303 and the upper housing 201 is rotated to a certain angle, so that heatable material can be added or the hookah device can be cleaned.

[0081] The present invention provides a heat insulation structure and a hookah device. The lower heating component 100 is spaced apart from the inner surface of the lower housing 101 to form a lower heat insulation cavity, and the upper heating component 200 is spaced apart from the inner surface of the upper housing 201 to form an upper heat insulation cavity. The heat generated by the lower heating component 100 is isolated from the lower housing 101 through the lower heating cavity to ensure that the temperature of the lower housing 101 will not cause burns to the consumer, and the heat generated by the upper heating component 200 is isolated from the upper housing 201 through the upper heating cavity to ensure that the temperature of the upper housing 201 will not cause burns to the consumer. This effectively avoids the risk of burns to the consumer when holding the lower housing 101 and the upper housing 201 during use, greatly improving the consumer's comfort and making it popular with consumers.

[0082] Furthermore, the hookah device provided by this utility model includes the upper heating assembly 200 and the lower heating assembly 100. The lower heating assembly 100 includes a lower heating bowl 105 with a lower heating cavity 1052 and a lower heating unit 106 disposed on the top of the lower heating bowl 105. The lower heating bowl 105 and the upper heating bowl 205 together form a heating space. The lower heating unit 106 and the upper heating unit 206 simultaneously provide the heat energy required for heating the heatable material in the material basket of the heating space, thereby ensuring that the heating space can heat up quickly and heat the heatable material in a short time to produce a large amount of atomized material for consumers to inhale, which is very popular among consumers.

[0083] 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.
