Description

Technical Field

[0001] This utility model relates to the field of smoking devices, and in particular to a thick-film power supply pressing structure and a hookah device. Background Technology

[0002] As a culturally distinctive smoking method, hookah uses a specially designed hookah device to filter the smoke from atomized tobacco products with water or other liquids, providing smokers with a relatively mild and somewhat enjoyable smoking experience.

[0003] Traditional hookah uses charcoal to heat the tobacco, which releases carbon monoxide, posing a potential health threat to smokers. To overcome this problem, a thick-film heating structure has been developed to heat the tobacco, thus avoiding carbon monoxide production and significantly improving smoker safety.

[0004] However, most existing hookah devices with thick-film heating structures use solder connections for external power supply. When smokers smoke for too long or increase the heating power, the thick-film heating structure continues to heat up and the temperature can reach over 200°C. At this time, the soldered external power supply connection is very prone to melting or even falling off, which ultimately leads to the failure of the circuit power supply function and seriously affects the smoker's smoking experience. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a thick film power supply pressing structure and a water pipe device that are simple in structure and can maintain a stable power supply connection.

[0006] This utility model discloses a thick-film power supply pressing structure, including a thick-film heating component and a power supply pressing component. The thick-film heating component includes a thick-film heating substrate and a resistive circuit printed on the outer surface of the bottom wall of the thick-film heating substrate. The end of the resistive circuit is provided with a conductive contact. A fixing post is also welded on the thick-film heating substrate. The conductive contact of the resistive circuit is spaced apart from the fixing post. The power supply pressing component includes a conductive pad and a pressing block. The conductive pad is sleeved around the fixing post and electrically connected to the conductive contact. The pressing block presses an external power supply terminal sleeved around the fixing post onto the conductive pad to maintain electrical continuity between the external power supply terminal and the conductive contact of the resistive circuit through the conductive pad.

[0007] Furthermore, the conductive contacts of the resistive circuit are ring-shaped and are arranged around the periphery of the fixed post and spaced apart from the fixed post.

[0008] Furthermore, the side of the conductive pad that contacts the external power supply terminal completely covers the end of the external power supply terminal.

[0009] Furthermore, the side of the conductive pad that contacts the conductive contact completely covers the conductive contact.

[0010] Furthermore, the pressure block is arranged in a ring around the periphery of the fixed column, and the side of the pressure block that contacts the external power supply terminal completely covers the end of the external power supply terminal.

[0011] Furthermore, the pressure block is a voltage-conducting block.

[0012] Furthermore, the thick film power supply pressing structure also includes a fastener, and the outer periphery of the fixing post is provided with threads. The fastener is threadedly connected to the fixing post and abuts against the pressing block.

[0013] Furthermore, conductive contacts are provided at both ends of the resistive circuit of the thick film heating substrate, and each conductive contact is electrically connected to an external power supply terminal through the power supply crimping assembly.

[0014] Furthermore, the thick film heating substrate is a heating bowl with a heating cavity. The resistive circuit and the conductive contacts are printed on the outer surface of the bottom wall of the heating bowl, and the fixing post is welded to the outer surface of the bottom wall of the heating bowl. The power supply crimping assembly is located on the outer surface of the bottom wall of the heating bowl and is electrically connected to an external power supply to provide heat to the heating cavity of the heating bowl.

[0015] This utility model discloses a hookah device, including the aforementioned thick film power supply pressing structure.

[0016] The thick-film power supply crimping structure provided by this utility model employs a power supply crimping assembly that is crimped onto the resistive circuit of the thick-film heating assembly. In conjunction with the pressure block, the external power supply terminal, which is sleeved around the fixed post, is crimped onto the conductive pad to maintain electrical continuity between the external power supply terminal and the conductive contact of the resistive circuit through the conductive pad. By clamping the external power supply terminal between the conductive pad and the pressure block, the connection structure is made stable. The conductive spring, positioned between the conductive contact and the external power supply terminal, provides an anti-detachment function, further enhancing the stability of the connection structure. Furthermore, the hookah device provided by this utility model, using the aforementioned thick-film power supply crimping structure, ensures a stable connection between the external power supply terminal and the thick-film heating assembly, avoiding instability factors such as power disconnection during heating, and greatly improving the consumer's smoking experience. The thick-film power supply crimping structure and hookah device provided by this utility model are not only simple in structure but also maintain a stable power connection, making them popular with consumers.

They are used 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 limiting the invention.

[0055] 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.

[0056] Please see Figures 1-35This invention discloses a hookah device that uses a thick-film power supply pressing structure to power and heat a heatable material to generate smoke for consumers to inhale. The thick-film power supply pressing structure includes a thick-film heating component and a power supply pressing component. The power supply pressing component is connected to an external power source to power the thick-film heating component, which then converts the electrical energy into heat energy to heat the heatable material in the hookah device.

[0057] In this embodiment, the thick-film heating assembly includes a thick-film heating substrate and a resistive circuit printed on the outer surface of the bottom wall of the thick-film heating substrate. The end of the resistive circuit is provided with a conductive contact. A fixing post is also welded to the outer surface of the thick-film heating substrate. The conductive contact of the resistive circuit is spaced apart from the fixing post. The power supply crimping assembly includes a conductive pad and a pressing block. The conductive pad is sleeved around the fixing post and electrically connected to the conductive contact. The pressing block presses the external power supply terminal sleeved around the fixing post onto the conductive pad to maintain electrical continuity between the external power supply terminal and the conductive contact of the resistive circuit through the conductive pad.

[0058] More specifically, the thick film heating substrate is a heating bowl with a heating cavity, the resistive circuit and the conductive contacts are printed on the outer surface of the bottom wall of the heating bowl, and the fixing post is welded to the outer surface of the bottom wall of the heating bowl. The power supply crimping assembly is located on the outer surface of the bottom wall of the heating bowl and is electrically connected to an external power supply to provide heat to the heating cavity of the heating bowl.

[0059] For more details, please refer to Figures 1-10 In this embodiment, the thick film heating assembly includes a lower heating assembly 100 and an upper heating assembly 200 that cooperate with each other.

The upper heating assembly 200 includes an upper heating bowl 205 with an upper heating cavity 2052 and an upper heating unit 206 disposed on 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 106 and... The upper heating unit 206 is 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.

[0060] In this embodiment, the lower heating unit 106 is located on the outer surface of the lower heating bowl 105, and the upper heating unit 206 is located on the outer surface of the upper heating bowl 205, so as to prevent the heatable material or the smoke particles generated after the heatable material is heated from adhering to the lower heating unit 106 and the upper heating unit 206 and affecting the heating efficiency.

[0062] 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.

The air vent 1051 of the lower heating bowl 105 is connected to an air vent pipe assembly. The lower heating unit 106 is arranged to avoid the air vent pipe assembly. The material basket 107 is provided with a boss 1073 protruding upward at the position opposite to the air vent 1051. The boss 1073 is used to prevent the heatable material in the material basket 107 from falling into the air vent pipe assembly. 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.

[0065] Please see Figures 17-19 and Figure 21 In this embodiment, the lower heating bowl 105 is made of a thick film material. The lower heating unit 106 further includes a lower resistance circuit 1062 disposed on the outer surface of the bottom wall of the lower heating bowl 105 and a lower conductive contact 1063 located at the end of the lower resistance circuit 1062. A lower insulating layer is disposed between the lower resistance circuit 1062 and the lower heating bowl 105, and the lower resistance circuit 1062 is printed on the lower insulating layer. 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.

The lower connector 301 is connected to the lower housing 101, and the upper connector 302 is connected to the upper housing 201. The lower connector 301 and the upper connector 302 can move towards each other or away from each other in the vertical direction along the connecting shaft 303, and one of the lower connector 301 and the upper connector 302 can rotate axially relative to the other along the axis of the connecting shaft 303.

[0084] Please see Figures 1-3 The outer periphery of the upper housing 201 is also equipped with a handle 400. When a consumer needs to add heatable material to the heating space of the hookah device or clean the hookah device after use, he / she needs to hold and pull the handle 400 upward. 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.

[0085] The thick-film power supply crimping structure provided by this utility model employs a power supply crimping assembly that is crimped onto the resistive circuit of the thick-film heating assembly. In conjunction with the pressure block, the external power supply terminal, which is sleeved around the fixed post, is crimped onto the conductive pad to maintain electrical continuity between the external power supply terminal and the conductive contact of the resistive circuit through the conductive pad. By clamping the external power supply terminal between the conductive pad and the pressure block, the connection structure is made stable. The conductive spring, positioned between the conductive contact and the external power supply terminal, provides an anti-detachment function, further enhancing the stability of the connection structure. Furthermore, the hookah device provided by this utility model, using the aforementioned thick-film power supply crimping structure, ensures a stable connection between the external power supply terminal and the thick-film heating assembly, avoiding instability factors such as power disconnection during heating, and greatly improving the consumer's smoking experience. The thick-film power supply crimping structure and hookah device provided by this utility model are not only simple in structure but also maintain a stable power connection, making them popular with consumers.

[0086] Furthermore, the hookah device provided by the present invention, by setting a lower heating component 100 and an upper heating component 200, further, the lower heating component 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 component 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 106 and the upper heating unit 206 can simultaneously provide the heating space with the heat energy required for heating, 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 with consumers.

[0087] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto.
