Description

Technical Field

[0001] This invention relates to electronically heated hookahs, and more particularly to hookah devices with dual heating modules. Background Technology

[0002] Traditional hookahs typically rely on charcoal for heating, which suffers from problems such as inaccurate temperature control, uneven smoke distribution, the production of toxic gases during charcoal combustion, and pollution from combustion byproducts. Existing electrically heated hookah devices mostly employ a single heat source structure, resulting in slow heating speed, uneven heating, and a poor user experience.

[0003] Therefore, there is an urgent need for a hookah device that can solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a water pipe device with a dual heating module, which can simultaneously heat the smoke generating medium from the top wall and side of the pipe, resulting in fast heating speed, uniform heating, and a good user experience.

[0005] To achieve the above objectives, the present invention provides a hookah device with dual heating modules, including a housing, heating modules, a power supply module, and a hookah bowl. The power supply module supplies power to the heating modules. The heating modules include a first heating module located on the top wall of the mounting cavity and a second heating module that surrounds the mounting cavity from the side. The housing includes a lower shell having the mounting cavity and an upper shell on which the first heating module is mounted. The hookah bowl is accommodated in the mounting cavity and used to hold the smoke-generating medium. The bottom and top walls of the hookah bowl are provided with a plurality of air holes. The upper shell is fitted onto the lower shell to close the mounting cavity. An air intake channel is formed between the upper shell and the lower shell to communicate with the outside and the mounting cavity, or an air intake channel is formed inside the lower shell to communicate with the outside and the mounting cavity. The first heating module heats the top wall to heat the smoke-generating medium in the hookah bowl from the top wall. The second heating module surrounds the mounting cavity and heats the side walls of the hookah bowl to heat the smoke-generating medium in the hookah bowl from the side.

[0006] Preferably, the first heating module is a resistance heating module and includes a resistance heating element, or the first heating module is an electromagnetic heating module and includes an electromagnetic heating part and an electromagnetic induction element. The electromagnetic heating part emits a high-frequency electromagnetic signal to the electromagnetic induction element, so that the electromagnetic induction element of the first heating module generates eddy current effect and heats up. The resistance heating element or electromagnetic induction element of the first heating module is plate-shaped and forms the bottom wall of the upper shell. When the upper shell is fitted onto the lower shell, the resistance heating element or electromagnetic induction element of the first heating module contacts the top wall of the tobacco bowl.

[0007] Specifically, when the resistive heating element or electromagnetic induction element of the first heating module is plate-shaped and forms the bottom wall of the upper shell, a heat-resistant plate with a gap between it and the bottom wall of the upper shell is also formed on the side of the bottom wall of the upper shell away from the mounting cavity. The air inlet channel is formed between the bottom wall of the upper shell and the heat-resistant plate, and several air holes are opened on the bottom wall of the upper shell to connect with the mounting cavity. This solution allows the gas entering the tobacco bowl to be preheated by the first heating module, resulting in a better smoking experience. It also effectively utilizes the heating efficiency of the first heating module, preventing the temperature of the control part inside the lower shell from becoming too high.

[0008] Preferably, the top wall of the smoke bowl includes a metal top wall that can be electromagnetically induced, and the first heating module includes an electromagnetic heating unit. The electromagnetic heating unit of the first heating module emits a high-frequency electromagnetic signal to the metal top wall, causing the metal top wall to generate an eddy current effect and heat the smoke-generating medium in the smoke bowl. This solution enables the top wall of the smoke bowl to actively heat up, resulting in a high heating rate and energy savings.

[0009] Preferably, the second heating module is a resistance heating module and includes a resistance heating element, or the second heating module is an electromagnetic heating module and includes an electromagnetic heating part and an electromagnetic induction element, wherein the resistance heating element or electromagnetic induction element of the second heating module is annular and surrounds the cavity wall of the mounting cavity.

[0010] Preferably, the sidewall of the smoke bowl includes an annular metal wall that can be electromagnetically induced, and the second heating module includes an electromagnetic heating unit. The electromagnetic heating unit of the second heating module emits a high-frequency electromagnetic signal to the annular metal wall, causing the annular metal wall to generate an eddy current effect and heat the smoke-generating medium in the smoke bowl. This solution enables the sidewall of the smoke bowl to actively heat up, resulting in a high heating rate and energy savings.

[0011] Preferably, the top wall of the tobacco bowl is recessed into the tobacco bowl to form a first groove, and the groove wall of the first groove has a plurality of air holes. When the upper shell is fitted onto the lower shell, the bottom wall of the upper shell contacts the top wall of the tobacco bowl and forms a heating zone connecting the air intake channel and the air holes between the upper shell and the first groove of the top wall. This design not only allows the first heating module to mainly heat the top surface of the tobacco bowl that is offset from the first groove, preventing the smoke generating medium in the tobacco bowl from overheating and charring, but also allows the first heating module to preheat the air in the heating zone, so that the gas entering the tobacco bowl is hot gas.

[0012] Specifically, there are multiple first grooves arranged in a ring shape, and the multiple first grooves are arranged concentrically on the top wall of the tobacco bowl. Of course, the first grooves can also be spirally coiled on the top wall, or in other patterns such as crosses, and are not limited to a concentric ring structure.

[0013] Specifically, the first groove has an arc-shaped cross-section. This design ensures that when the first heating module heats the top wall, it only heats a very small area of ​​the top wall, preventing the smoke-generating medium in the smoke bowl from overheating and charring locally. Furthermore, the arc-shaped cross-section of the air hole allows the airflow to enter the smoke bowl in multiple directions as it passes through the air hole, thus diffusing the hot airflow and making the temperature in the smoke bowl more uniform.

[0014] Preferably, the bottom wall of the tobacco bowl is recessed outward to form a second groove, the second groove is annular, and a plurality of the second grooves are arranged concentrically on the bottom wall of the tobacco bowl.

[0015] Preferably, the smoke pot includes a body containing a smoke-generating medium and a lid covering the opening of the body. The top wall is formed on the lid, and the bottom wall is formed on the bottom wall of the body. The lid is equipped with a handle for easy opening. The lid can be fastened to the body or simply placed on the body.

[0016] Preferably, the smoke pot is a metal pot, such as a stainless steel pot or a stainless steel pot.

[0017] Preferably, the hookah device with dual heating modules further includes a base support, which is installed on the lower side of the mounting cavity of the lower shell and has a sealed air pipe communicating with the mounting cavity. The base support also has a buffer channel connecting the bottom wall of the receiving cavity to the outside. The buffer channel can evenly distribute the temperature during smoking and buffer the water pressure after smoking to prevent excessive water from entering the bowl along the main flue.

[0018] Preferably, an annular sealing sleeve is installed inside the base bracket, the sealing air tube is formed in the annular sealing sleeve, and the buffer channel is formed between the annular sealing sleeve and the base bracket.

[0019] Preferably, the dual-heating-module hookah device further includes a control circuit. The upper shell has a first temperature sensor for detecting the temperature of the first heating module or the hookah bowl, and the lower shell has a second temperature sensor for detecting the temperature of the second heating module or the hookah bowl. The control circuit controls the first heating module to operate within a first temperature range based on the first temperature detected by the first temperature sensor, and controls the second heating module to operate within a second temperature range based on the second temperature detected by the second temperature sensor. The first temperature range is greater than the second temperature range. The first heating module has a high heating temperature and can preheat the gas about to enter the hookah bowl, while the second heating module has a lower heating temperature but a larger heating area, achieving uniform heating while preventing the smoke-generating medium from overheating and charring.

[0020] Specifically, the first temperature range is 200-320℃, and the second temperature range is 100-200℃. Compared with existing water pipe heating technologies, this invention significantly reduces the heating temperature while increasing heating efficiency, preventing the smoke-generating medium from charring and improving the user experience. Furthermore, this invention limits the temperature of the side heating of the pipe to below 200℃, ensuring uniform heating while preventing localized overheating of the smoke-generating medium.

[0021] Preferably, the lower shell and the upper shell have a surrounding mounting cavity and a first annular wall and a second annular wall on opposite sides, respectively. When the lower shell and the upper shell are installed together, the first annular wall and the second annular wall are engaged and close the mounting cavity.

[0022] Specifically, the water fumigation device with dual heating modules further includes an electrical connection assembly, which includes an elastic probe mounted on one of the first annular wall and the second annular wall, and a conductive block mounted on the other of the first annular wall and the second annular wall and corresponding to the elastic probe; when the lower shell and the upper shell are installed together, the elastic probe contacts the conductive block and is electrically connected to the conductive block, so that the second heating module is electrically connected to the power supply module through the electrical connection assembly.

[0023] Specifically, the first annular wall and / or the second annular wall have slots connecting the outer and inner edges. The sealing element is offset from the slots. When the lower and upper shells are installed together, the first and second annular walls are in sealed contact through the sealing element, and an air inlet communicating with the air intake channel is formed at the slots. The air inlet is located between the lower and upper shells, eliminating the need for a separate air inlet within the upper or lower shell, thus saving costs.

[0024] Preferably, the upper and lower shells are relatively independent, and the first and second annular walls have magnetic components for magnetic attraction, allowing the lower and upper shells to be positioned and attracted to each other without the need for locking, making operation convenient and providing a good user experience. In this design, the upper shell can be completely detached from the lower shell to open the mounting cavity, or it can be positioned and attracted to the lower shell by the magnetic components to close the mounting cavity. Of course, the upper shell can also be flipped or rotated relative to the lower shell to open or close the mounting cavity.

[0025] More preferably, the magnetic component includes a plurality of first magnet blocks disposed within the first annular wall and a plurality of second magnet blocks disposed within the second annular wall. The plurality of first magnet blocks are spaced apart around the center of the first annular wall and have opposite magnetic properties, with first magnet blocks of different magnetic properties arranged adjacent to each other. Similarly, the plurality of second magnet blocks are spaced apart around the center of the second annular wall and have opposite magnetic properties, with second magnet blocks of different magnetic properties arranged adjacent to each other. The opposing faces of corresponding first magnet blocks and second magnet blocks have opposite magnetic properties. This design allows the lower and upper shells to automatically align using the magnetism of the magnetic component, facilitating precise alignment of the electrical connection components between the lower and upper shells.

[0026] Compared to existing technologies, this invention features two heating modules surrounding the smoke-generating medium. The first heating module heats the smoke-generating medium from the top wall of the smoke bowl, aligning the heating direction with the gas flow direction. This facilitates direct heating of the smoke-generating medium while simultaneously providing air-assisted heating. The second heating module surrounds the smoke-generating medium from the sides of the smoke bowl, ensuring uniform heating while also maintaining the temperature of the smoke bowl and preventing excessive temperature drop. Furthermore, heating the top wall of the smoke bowl with the first heating module and the side walls with the second effectively increases the heating area and improves heating efficiency. Moreover, the simultaneous heating from the top and sides by the two heating modules results in more uniform heating within the smoke bowl, providing a better user experience.

[0040] To illustrate the technical content, structural features, objectives, and effects of the present invention in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0041] Example 1: refer to Figures 1 to 3 This invention discloses a hookah device with dual heating modules, including a housing 10, heating modules, a power supply module 20, and a hookah bowl 30. The power supply module 20 supplies power to the heating modules. The heating modules include a first heating module 41 located on the top wall 302 of the mounting cavity 131 and a second heating module 42 surrounding the mounting cavity 131 laterally. The housing 10 includes a lower shell 11 having the mounting cavity 131 and an upper shell 12 for mounting the first heating module 41. The hookah bowl 30 is accommodated in the mounting cavity 131 and used to hold the smoke generating medium 200. The bottom wall 301 and top wall 302 are provided with a plurality of air holes 321 and 311. The upper shell 12 is fitted onto the lower shell 11 to close the mounting cavity 131. An air inlet channel 132 is formed inside the shell 10 to connect the outside world and the mounting cavity 131. The first heating module 41 heats the top wall 302 to heat the smoke generating medium 200 in the smoke bowl 30 from the top wall 302. The second heating module 42 surrounds the mounting cavity 131 and heats the side wall 303 of the smoke bowl 30 to heat the smoke generating medium 200 in the smoke bowl 30 from the side.

[0042] The air intake passage 132 is formed in the upper shell 12. Of course, the air intake passage 132 can also be formed between the upper shell 12 and the lower shell 11.

[0043] refer to Figure 1 , Figure 3 and Figure 4The hookah device with dual heating modules also includes a base bracket 14, which is installed on the lower side of the mounting cavity 131 of the lower shell 11 and has a sealed air pipe 134 communicating with the mounting cavity 131. A buffer channel 135 is also formed on the base bracket 14, connecting the bottom wall 301 of the receiving cavity to the outside. The buffer channel 135 can evenly distribute the temperature during smoking and buffer the water pressure after smoking to prevent excessive water from entering the bowl 30 along the main flue.

[0044] refer to Figure 1 and Figure 3 An annular sealing sleeve 141 is installed inside the base support 14, a sealing air tube 134 is formed in the annular sealing sleeve 141, and a buffer channel 135 is formed between the annular sealing sleeve 141 and the base support 14.

[0045] During operation, the lower shell 11 is placed in the water container 50 via the base support 14. The protruding tube at the top of the water container 50 is inserted into the sealed air tube 134 and makes sealed contact with the sealed air tube 134. The air tube 51 inside the protruding tube is inserted below the water surface in the water container 50. When the user smokes, the air is drawn through the straw 52 in the water container 50. Figure 4 Smoking through the trachea in the direction of the arrow.

[0046] refer to Figure 2 , Figures 8 to 10 The smoke bowl 30 includes a bowl body 31 for containing a smoke-generating medium 200 and a lid 32 for covering the opening of the bowl body 31. A top wall 302 is formed on the lid 32, and a bottom wall 301 is formed on the bottom wall 301 of the bowl body 31. (Reference) Figure 9 and Figure 10 Unlike embodiment 1, in another embodiment, the lid 32 is equipped with a handle 33. The handle 33 facilitates opening the lid 32, is rotatably mounted on the lid 32, and can be folded relative to the lid 32. The lid 32 can be fastened to the pot body 31, or it can simply cover the pot body 31. Of course, the top wall 302 can also be formed on the pot body 31, in which case the bottom wall 301 is formed on the lid 32.

[0047] refer to Figure 3 , Figure 8 and Figure 9The top wall 302 of the smoke bowl 30 is recessed into the smoke bowl 30 to form a first groove 322. A plurality of air holes 321 are formed on the groove wall of the first groove 322. When the upper shell 12 is fitted onto the lower shell 11, the bottom wall of the upper shell 12 contacts the top wall 302 of the smoke bowl 30 and forms a heating zone connecting the air intake channel 132 and the air holes 321 between the two. This design not only allows the first heating module 41 to primarily heat the top surface of the smoke bowl 30 that is offset from the first groove 322, preventing the smoke generating medium 200 inside the smoke bowl 30 from overheating and charring, but also allows the first heating module 41 to preheat the air in the heating zone, ensuring that the gas entering the smoke bowl 30 is hot gas.

[0048] The first groove 322 is multiple and annular, and the multiple first grooves 322 are concentrically spaced on the top wall 302 of the smoke bowl 30. Of course, the first grooves 322 can also be spirally coiled on the top wall 302, or in other patterns such as crosses, and are not limited to annular concentric structures. Specifically, the cross-section of the first groove 322 is arc-shaped. Of course, the cross-section of the first groove 322 can also be V-shaped, U-shaped, or rectangular. refer to Figure 3 and Figure 10 The bottom wall 301 of the tobacco bowl 30 is recessed outward to form a second groove 312. The second groove 312 is annular, and multiple second grooves 312 are arranged concentrically on the bottom wall 301 of the tobacco bowl 30. Air holes 311 are provided on the bottom wall 301, some of which are located in the first groove 312, and some are located outside the first groove 312.

[0049] The cooking pot 30 is a metal pot, such as a stainless steel pot or a copper pot. The pot body 31 and the pot lid 32 are integrally formed.

[0050] refer to Figure 1 , Figure 2 and Figure 4 The first heating module 41 is an electromagnetic heating module and includes an electromagnetic heating part 411 and an electromagnetic induction element 412. The electromagnetic heating part 411 emits a high-frequency electromagnetic signal to the electromagnetic induction element 412, causing the electromagnetic induction element 412 of the first heating module 41 to generate eddy currents and heat up. The electromagnetic induction element 412 of the first heating module 41 is plate-shaped and forms the bottom wall of the upper shell 12. When the upper shell 12 is fitted onto the lower shell 11, the electromagnetic induction element of the first heating module 41 contacts the top wall 302 of the smoke pot 30. The electromagnetic induction element 412 is a magnetically conductive alloy plate.

[0051] Specifically, a heat-resistant plate 122 with a gap is formed on the side of the bottom wall of the upper shell 12 (electromagnetic induction element 412) away from the mounting cavity 131. The air inlet channel 132 is formed between the bottom wall of the upper shell 12 and the heat-resistant plate 122, serving as a heating buffer space. Several air holes 4121 are provided on the bottom wall of the upper shell 12 (electromagnetic induction element 412) to connect to the mounting cavity 131. The heat-resistant plate 122 is preferably made of a material with heat insulation function that does not affect electromagnetic induction, such as mica sheet.

[0052] Of course, in another embodiment, the first heating module 41 is a resistance heating module and includes a resistance heating element, using the resistance heating element instead of the electromagnetic induction element 412. The resistance heating element of the first heating module 41 is a thick-film heating element, a thin-film heating element, or a ceramic heating element.

[0053] refer to Figure 1 , Figure 3 and Figure 4 The sidewall 303 of the smoke bowl 30 includes an annular heating element, which is part of the second heating module 42 and constitutes at least a portion of the sidewall 303 or the normal sidewall 303. The second heating module 42 includes a driving unit and a heating element. The driving unit, powered by the power supply module 20, causes the heating element to actively heat up in order to heat the smoke generating medium (smoke paste) in the smoke bowl 30.

[0054] Specifically, the side wall 303 of the smoke bowl 30 includes an annular metal wall that can be electromagnetically induced. The second heating module 42 includes an electromagnetic heating part 421. The annular metal wall that can be electromagnetically induced serves as the electromagnetic induction heating element of the second heating module 42. The electromagnetic heating part 421 of the second heating module 42 emits a high-frequency electromagnetic signal to the annular metal wall, causing the annular metal wall to generate an eddy current effect and heat the smoke generating medium 200 in the smoke bowl 30. This solution enables the side wall 303 of the smoke bowl 30 to actively heat up, resulting in a high heating rate and energy savings. The side wall 303 can be directly an annular metal wall, or it can include an annular metal wall and a buffer layer located on the inner or outer wall of the annular metal wall.

[0055] The second heating module 42 further includes a heat insulation layer 422 surrounding the electromagnetic heating part 421, which can be an aerosol. In this embodiment, a bracket forming a mounting cavity 131 is installed in the lower shell 11. The cavity wall (non-electromagnetic induction material) of the mounting cavity 131 is formed on the bracket. The winding coil of the electromagnetic heating part 421 is wound around the outside of the bracket and passes through the cavity wall of the mounting cavity 131 to induction heat the side wall 303 of the smoke pot 30.

[0056] The mounting cavity 131 has a gap between its cavity wall and the tobacco bowl 30, and a heat insulation component 112 is provided at the bottom of the mounting cavity 131 to prevent the tobacco bowl 30 from damaging the bottom wall of the mounting cavity 131.

[0057] Specifically, the side wall of the tobacco bowl 30 can also be a resistance heating ring. In this case, the mounting cavity 131 is provided with a power supply terminal that is electrically connected to the power supply module 20. When the tobacco bowl 30 is installed on the mounting cavity 131, the conductive end of the resistance heating ring on the side wall of the tobacco bowl 30 is inserted into or abutted against the power supply terminal, so that the power supply module 20 supplies power to the resistance heating ring on the side wall 303 of the tobacco bowl 30, causing the resistance heating ring to heat up. The resistance heating ring can be a resistance wire embedded in the side wall 303 of the tobacco bowl 30, or it can be formed by a thin film resistance heating plate or a thick film resistance heating plate, or it can be a ceramic heating wall.

[0058] In this embodiment, the first heating module 41 heats the top wall 302 indirectly by means of a heating plate made of an electromagnetic induction element 412 (or a resistive heating element) through heat transfer, thereby indirectly heating the smoke generating medium 200 in the smoke bowl 30. The second heating module directly heats the electromagnetically induction-sensitive side wall 303 of the smoke bowl 30 through an electromagnetic heating part 421, thereby directly heating the smoke generating medium 200 in the smoke bowl 30.

[0059] The electromagnetic heating part 411 of the first heating module 41 is an electromagnetic winding coiled in the upper shell 12. The electromagnetic winding is coiled around the transverse center of the upper shell 12 and is coiled into a disc shape or block shape. The electromagnetic heating part 421 of the second heating module 42 is an electromagnetic winding coiled around the mounting cavity 131 and is coiled into a ring shape.

[0060] To prevent the heat from the first heating module 41 from affecting the power supply module 20 and the control circuit, a heat insulation plate 123 is provided on the side of the first heating module 41 away from the mounting cavity 131. The heat insulation plate is a mica heat insulation plate.

[0061] The dual-heating-module hookah device also includes a control circuit. The upper shell 12 has a first temperature sensor for detecting the temperature of the first heating module 41 or the hookah bowl 30, and the lower shell 11 has a second temperature sensor for detecting the temperature of the second heating module 42 or the hookah bowl 30. The control circuit controls the first heating module 41 to operate within a first temperature range based on the first temperature detected by the first temperature sensor, and controls the second heating module 42 to operate within a second temperature range based on the second temperature detected by the second temperature sensor. The first temperature range is greater than the second temperature range. The first heating module 41 has a high heating temperature and can preheat the gas about to enter the hookah bowl 30. The second heating module 42 has a lower heating temperature but a larger heating area, achieving uniform heating while preventing the smoke-generating medium 200 from overheating and charring.

[0062] The first temperature sensor is installed on the side of the electromagnetic heating part 411 away from the mounting cavity 131 and detects the temperature of the electromagnetic heating part 411. The second temperature sensor is installed on the bottom wall of the mounting cavity 131 and detects the temperature of the bottom wall 301 of the smoke bowl 30. Of course, it is not limited to this, the first temperature sensor can also be directly installed on the bottom wall of the upper shell 12 to directly detect the temperature of the top wall of the smoke bowl 302.

[0063] Specifically, the first temperature range is 200-320℃, and the second temperature range is 100-200℃. Preferably, the first temperature range is 230-280℃, and the second temperature range is 120-200℃. Compared to existing water pipe heating technologies, this invention significantly reduces the heating temperature while increasing heating efficiency, preventing the smoke-generating medium 200 from charring and improving the user experience. Furthermore, this invention limits the side heating temperature of the pipe bowl 30 to below 200℃, ensuring uniform heating while preventing localized overheating of the smoke-generating medium 200.

[0064] refer to Figure 1 The power supply module 20 includes a battery 21 and a conversion control circuit that controls the conversion of the electricity from the battery 21. The hookah device with the dual heating modules also includes a first circuit board 251 and a second circuit board 252. The control circuit is mounted in the first circuit board 251, and part of the conversion control circuit is mounted in the first circuit board 251 and part in the second circuit board 252. The conversion control circuit converts the battery's electrical energy into direct current to power the first circuit board 251 and the second circuit board 252, and converts the battery's electrical energy into corresponding drive signals to power the first heating module 41 and the second heating module 42.

[0065] refer to Figure 5 and Figure 6 The lower shell 11 and the upper shell 12 each have a surrounding mounting cavity 131 and a first annular wall 111 and a second annular wall 121 on opposite sides. When the lower shell 11 and the upper shell 12 are installed together, the first annular wall 111 and the second annular wall 121 engage and abut against each other to seal the mounting cavity 11. Specifically, the electromagnetic induction element 412 is surrounded by a sealing element to seal the gap between the electromagnetic induction element 412 and the edge of the tobacco bowl. This ensures that during operation, the electromagnetic induction element 412 is in close contact with the top wall 302 of the tobacco bowl 30 to form a high-temperature heating zone. The electromagnetic induction element 412 is surrounded by a sealing element to seal the gap between the electromagnetic induction element 412 and the edge of the tobacco bowl.

[0066] refer to Figure 5The dual-heating module water pipe device also includes an electrical connection assembly, which includes an elastic probe 261 mounted on one of the first annular wall 111 and the second annular wall 121, and a conductive block 262 mounted on the other of the first annular wall 111 and the second annular wall 121 and corresponding to the elastic probe 261. When the lower shell 11 and the upper shell 12 are installed together, the elastic probe 261 contacts the conductive block 262 and is electrically connected to the conductive block 262, so that the second heating module 42 is electrically connected to the power supply module 20 through the electrical connection assembly.

[0067] Reference image Figure 2 and Figure 6 The first annular wall 111 has a slot connecting its outer and inner edges. The sealing element is offset from the slot. When the lower shell 11 and upper shell 12 are installed together, the first annular wall 111 and the second annular wall 121 are in sealed contact through the sealing element, and an air inlet 133 communicating with the air intake channel 132 is formed at the slot. The air inlet 133 is located between the lower shell 11 and the upper shell 12, eliminating the need to form a separate air inlet 133 inside the upper shell 12 or the lower shell 11, thus saving costs. Of course, the air inlet 133 can also be located on the upper shell 12. Of course, the slot can also be formed on the second annular wall 121.

[0068] refer to Figure 5 and Figure 6 The upper shell 12 and the lower shell 11 are relatively independent, allowing the upper shell 12 to be directly removed from the lower shell 11 to completely detach from it. The first annular wall 111 and the second annular wall 121 have magnetically engaging components to position and engage the lower shell 11 and the upper shell 12 relative to each other, eliminating the need for locking and positioning, thus providing convenient operation and a better user experience. Specifically, the magnetic components include multiple first magnet blocks 61 disposed within the first annular wall 111 and multiple second magnet blocks 62 disposed within the second annular wall 121. The multiple first magnet blocks 61 are spaced apart around the center of the first annular wall 111 and have opposite magnetic properties; the first magnet blocks 61 with different magnetic properties are arranged adjacent to each other. Similarly, the multiple second magnet blocks 62 are spaced apart around the center of the second annular wall 121 and have opposite magnetic properties; the second magnet blocks 62 with different magnetic properties are arranged adjacent to each other, and the opposing surfaces of the first magnet blocks 61 and second magnet blocks 62 at corresponding positions have opposite magnetic properties. This design allows the lower shell 11 and the upper shell 12 to automatically align using the magnetic properties of the magnetic components, facilitating precise alignment of the electrical connection components between the lower shell 11 and the upper shell 12.

[0069] Specifically, the second annular wall 121 and the first annular wall 111 are also provided with matching and engaging components. The matching and engaging components include an engaging groove 63 provided on the first annular wall 111 and an engaging protrusion 64 provided on the second annular wall 121. The engaging groove 63 and the engaging protrusion 64 engage with each other to achieve circumferential positioning between the first annular wall 111 and the second annular wall 121.

[0070] The upper casing 12 is equipped with a display screen 22 and a button 23. The user controls the control circuit inside the upper casing through the button 23. The control circuit controls the display screen 22 to display the current working status, battery power information, etc. The upper casing 12 also has a charging interface 24 connected to the power supply module 20. This charging interface 24 is a YE C interface, etc.

[0071] Example 2: refer to Figure 11 Unlike Embodiment 1, in this embodiment, the top wall 302 of the smoke bowl 30 includes a metal top wall 302 that can be electromagnetically induced. The first heating module 41 includes an electromagnetic heating part 411. The electromagnetic heating part 411 of the first heating module 41 emits a high-frequency electromagnetic signal to the metal top wall 302, causing the metal top wall 302 to generate an eddy current effect and heat the smoke generating medium 200 in the smoke bowl 30. This solution enables the top wall 302 of the smoke bowl 30 to actively heat up, resulting in a high heating rate and energy savings.

[0072] refer to Figure 11 To facilitate sealing the mounting cavity 131, the bottom wall of the upper shell 12 is a non-magnetic insulating plate 412a. The insulating plate 412a has several air holes 4121. When the upper shell 12 covers the lower shell 11, the insulating plate 412a covers the top wall 302 of the tobacco bowl 30 and seals the mounting cavity 131 through the surrounding seals. The air inlet channel 132 is located on the side of the insulating plate 412a away from the mounting cavity 131.

[0073] Specifically, the insulating plate 412a is a heat-conducting plate with good thermal conductivity, such as a ceramic plate. A heat-resistant plate 122 is also formed on the side of the insulating plate 412a away from the mounting cavity 131. The air inlet channel 132 is formed between the insulating plate 412a and the heat-resistant plate 123. A plurality of air holes 4121 are provided on the bottom wall (electromagnetic induction element 412) of the upper shell 12 to connect to the mounting cavity 131. The heat-resistant plate 122 is preferably made of a material with heat insulation function that does not affect electromagnetic induction, such as mica.

[0074] Example 3: Unlike Embodiments 1 and 2, in this embodiment, the second heating module 42 is a resistance heating module and includes a resistance heating element, or the second heating module 42 is an electromagnetic heating part and includes an electromagnetic heating part and an electromagnetic induction element. The resistance heating element or electromagnetic induction element of the second heating module 42 is annular and surrounds the cavity wall of the mounting cavity 131.

[0075] The resistance heating element of the second heating module 42 is a thick film heating element, a thin film heating element, or a ceramic heating element.

[0076] When the smoke bowl 30 is installed in the mounting cavity 131, the side wall 303 contacts the cavity wall of the mounting cavity so that the resistance heating element or electromagnetic induction element heats the smoke bowl 30 through heat conduction. It is preferable to use a heat-resistant material with good thermal conductivity, such as metal or ceramic, for the side wall of the smoke bowl 30.

[0077] In the above embodiment, the battery 21 is fixedly mounted on the upper casing 12. In contrast, see reference [reference needed]. Figure 12 In embodiment 3, the battery 21 is a removable battery. A battery slot 120 for installing the battery 21 is provided on the upper side of the upper shell 12. The battery box containing the battery 21 is installed in the battery slot 120. When charging is required, the battery box of the battery 21 can be pulled out. In addition, there is a battery switch assembly between the battery slot 120 and the battery box. The battery switch assembly includes a manual switch 212, a rotation transmission member 213 and a latch 214. The rotation transmission member 213 is rotatably installed in the upper shell 12. Under normal conditions, the rotation transmission member 213 rotates under the drive of the elastic member so that the latch 214 rotates into the battery slot 120 and engages with the side wall of the battery box to prevent the battery box from accidentally detaching from the battery slot 120. When it is necessary to remove the battery box, operate the manual switch 212. The manual switch 212 drives its connecting rod to move downward, so as to press the rotating transmission component 213 to the inside of the rotation point, so that the rotating transmission component 213 can move the buckle 214 away from the battery box. Then pull out the battery box, charge the battery 21, and after it is fully charged, insert the battery box into the battery slot 120.

[0078] refer to Figure 13This is Embodiment 4 of the present invention, which differs from the above embodiments. In this embodiment, the air inlet 133 is located on the lower shell 11. The outer wall of the lower shell 11 protrudes upward from the first annular wall 111 to form a mounting groove. The second annular wall 121 of the upper shell 12 protrudes downward into the cover mounting groove, and the outer wall of the lower shell 11 abuts against the end of the outer wall of the upper shell 12. The annular sealing sleeve 141 inside the base bracket 14 is in direct contact with the base bracket 14 and does not form a buffer channel. The top protrusion 501 of the water container 50 is directly and sealed into the annular sealing sleeve 141 and communicates with the mounting cavity 131. The top wall 301 of the smoke pot 30 serves as a battery sensing element. The electromagnetic heating part 411 of the first heating module 41 directly emits a high-frequency electromagnetic signal to the top wall 301 of the smoke pot 30, so that the top wall 301 of the smoke pot 30 generates an eddy current effect and heats up.

[0079] Compared with the prior art, the present invention provides two sets of heating modules around the smoke bowl 30. The first heating module 41 heats the top wall 302 of the smoke bowl 30 directly or indirectly through electromagnetic heating or resistance heating, and the second heating module 42 heats the side wall 303 of the smoke bowl 30 directly or indirectly through electromagnetic heating or resistance heating. By heating the smoke bowl 30 from the top and the side simultaneously through the two sets of heating modules, the heating rate is not only effectively improved, but also the heating inside the smoke bowl 30 is more uniform, resulting in a better user experience.

[0080] The above-disclosed embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Therefore, any equivalent variations made in accordance with the scope of the present invention are still within the scope of the present invention.
