Embodiments for Carrying out the Invention

[0018] The present invention will be further described below in combination with the drawings and specific embodiments. It should be noted that, on the premise of not contradicting each other, new embodiments can be formed by arbitrarily combining the following-described embodiments or technical features with each other.

[0019] Referring to Figures 1 to 8, the present invention discloses an atomizing module used in an electromagnetic heating device. The atomizing module includes an atomizing device 10 and a heating device 20. The atomizing device 10 and the heating device 20 have a separated structural design, and the atomizing device 10 is engaged with one end of the heating device 20.

[0020] In this embodiment, the atomizing device 10 includes a first base body 11, a magnetic metal member 12, and a liquid guiding member 13. The liquid guiding member 13 can be made of a liquid guiding cotton, or a fibrous organic material, or a porous ceramic inorganic material. The liquid guiding member 13 has a plurality of void holes 131 inside, and the liquid can penetrate from one void hole 131 into another void hole 131. These void holes 131 communicate with each other. The first base body 11 has an exhaust passage 111, a holding chamber 112, a liquid storage tank 113, and several liquid supply holes 114. The liquid supply holes 114 are provided horizontally. The liquid storage tank 113 is used to store the liquid. The exhaust passage 111, the holding chamber 112, the liquid supply holes 114, and the liquid storage tank 113 communicate with each other in sequence. The exhaust passage 111 and the holding chamber 112 are recessed and communicated with the upper and lower two end faces of the first base body 11 respectively. The inner diameter of the holding chamber 112 is larger than the inner diameter of the exhaust passage 111.

[0021] The magnetic metal member 12 has a first through hole 121 and several interconnected through holes 122. The first through hole 121 is vertically penetrated along the length direction of the magnetic metal member 12. Both the magnetic metal member 12 and the liquid guiding member 13 are installed in the holding chamber 112. The first through hole 121 communicates with the exhaust passage 111. Also, several interconnected through holes 122 are all provided horizontally. Also, the interconnected through holes 122 communicate with the first through hole 121. The liquid guiding member 13 is made to be annular. The liquid guiding member 13 is covered outside the magnetic metal member 12. One end of the void hole 131 of the liquid guiding member 13 communicates with the interconnected through hole 122, and the other end communicates with the liquid supply hole 114. The liquid enters and stays in the void hole 131 of the liquid guiding member 13 from the liquid supply hole 114. The liquid guiding member 13 can transmit and store the liquid by using the void holes 131.

[0022] Furthermore, refer to FIGS. 9 to 13. The heating device 20 includes a second base body 21, a circuit board 22, a power battery 23, and a coil module 24. The power battery 23, the circuit board 22, and the coil module 24 are all fixed to the second base body 21. The power battery 23 is connected to the coil module 24 via the circuit board 22. A housing space 241 is recessed in the coil module 24. The first base body 11 is fixed to the heating device 20, and the magnetic metal member 12 is located within the housing space 241. The magnetic metal member 12 contacts the liquid via the liquid guiding member 13. Generally, the magnetic metal member 12 is made of a material such as iron or an iron alloy. The liquid can be a tobacco liquid. Therefore, it is required to use an environmentally friendly and food-grade magnetic metal member 12. Generally, ferrite, stainless steel, or other metal materials with an environmentally friendly heat-resistant coating treatment on the surface are used.

[0023] The power battery 23 supplies electricity to the coil module 24 via the circuit board 22. The program held in the circuit board 22 can generate an alternating magnetic field in the coil module 24. The surface of the magnetic metal member 12 generates an alternating current by cutting the alternating magnetic field. The current generates thermal energy by causing the charge carriers of the magnetic metal member 12 to move at high speed and irregularly. Also, the liquid flows from the liquid storage tank 113 and the liquid supply hole 114 into the void holes 131 of the liquid guiding member 13 and is stored. When the magnetic metal member 12 receives heat, the liquid on the liquid guiding member 13 is converted into gas and enters the interconnected holes 122. The interconnected holes 122 are mainly for allowing the atomized vapor generated by the liquid located at the portion in contact with the magnetic metal member 12 during heat generation to be ejected from the interconnected holes 122 and discharged from the exhaust passage 111 after passing through the interconnected holes 122.

[0024] An engaging groove 211 is recessed in the ceiling portion of the second base body 21, and the coil module 24 is fixed within the engaging groove 211. During separation, the accommodation space 241 faces the side of the first base body 11, and one end of the magnetic metal member 12 attached to the first base body 11 is inserted into the accommodation space 241. During the usage process, the atomizing device 10 is engaged into the accommodation space 241 of the heating device 20.

[0025] In this embodiment, the first base body 11 includes a liquid storage case 115 and a bottom base 116. The liquid storage case 115 includes a suction nozzle 1151 and a sleeve 1152. The suction nozzle 1151 has an exhaust passage 111, and the sleeve 1152 is provided to cover the outer wall of the suction nozzle 1151. The suction nozzle 1151 is elongated and is provided vertically. The exhaust passage 111 penetrates the entire suction nozzle 1151 along the length direction of the suction nozzle 1151. One end of the sleeve 1152 is connected to the outer wall of the central portion of the suction nozzle 1151, and the other end is provided at a distance from the suction nozzle 1151.

[0026] The bottom base 116 includes a bottom cover 1161 and a support base 1163. The bottom cover 1161 has an accommodation chamber 1162, and the support base 1163 protrudes from the bottom wall of the accommodation chamber 1162. The bottom base 116 has a second through hole 1164 and several of the above-described liquid supply holes 114. The second through hole 1164 extends so as to penetrate from the ceiling portion of the support base 1163 to the bottom of the bottom cover 1161. The bottom cover 1161 is engaged into the sleeve 1152, and the support base 1163 abuts against the bottom of the suction nozzle 1151. Also, the second through hole 1164 communicates with the first through hole 121. The liquid supply hole 114 is provided on the support base 1163 and communicates with the second through hole 1164. The liquid guiding member 13 is located within the second through hole 1164. The second through hole 1164 is stepped so as to facilitate adjustment of the loading positions of the liquid guiding member 13 and the magnetic metal member 12. The inner wall of the second through hole 1164 and the bottom surface of the suction nozzle 1151 surround the above-described holding chamber 112, and the inner wall of the accommodation chamber 1162, the outer wall of the support base 1163, the outer wall of the suction nozzle 1151, and the inner wall of the sleeve 1152 surround the above-described liquid storage tank 113.

[0027] The atomizing device 10 further includes a silicone base 14. The silicone base 14 is annular. The silicone base 14 is covered outside the support base 1163 and is located within the liquid storage tank 113. One end of the outer wall of the silicone base 14 abuts against the inner wall of the sleeve 1152 to form a sealed connection with the sleeve 1152. The other end of the outer wall of the silicone base 14 abuts against the inner wall of the bottom cover 1161 to form a sealed connection with the bottom cover 1161. Thereby, liquid leakage at the connection portion between the sleeve 1152 and the bottom cover 1161 is avoided. The distance from the ceiling portion of the silicone base 14 to the bottom of the bottom base 116 is smaller than the distance from the bottom end of the liquid supply hole 114 provided horizontally to the bottom of the bottom base 116. That is, the silicone base 14 cannot shield the liquid supply hole 114.

[0028] The sleeve 1152 includes a first pipe body 1153 and a second pipe body 1154 provided coaxially with the first pipe body 1153. Both the first pipe body 1153 and the second pipe body 1154 are annular. One end of the first pipe body 1153 is bent and then connected to the central portion of the outer wall of the suction nozzle 1151, and the other end is connected to the second pipe body 1154. The outer diameter of the second pipe body 1154 is smaller than the outer diameter of the first pipe body 1153, and a step is formed on the outer walls of the first pipe body 1153 and the second pipe body 1154. The second pipe body 1154 is located within the accommodation space 241, and the coil module 24 abuts against the stepped portion. Thereby, the axial distance between the atomizing device 10 and the heating device 20 is regulated. The second pipe body 1154 is provided at an interval from the suction nozzle 1151.

[0029] The magnetic metal member 12 includes a magnetic tube 123 and two engaging pieces 124 provided facing away from each other. The liquid guiding member 13 is covered outside the magnetic tube 123. The liquid guiding member 13 can abut against the bottom of the suction nozzle 1151. Both the mutual communication hole 122 and the first through hole 121 are provided in the magnetic tube 123. One end of the engaging piece 124 is connected to one end of the magnetic tube 123 that is separated from the suction nozzle 1151, and the other end is engaged with the liquid guiding member 13. Generally, the liquid guiding member 13 is in close contact with the magnetic tube 123. Also, the magnetic tube 123 adopts an annular structure. Such a structure is relatively excellent in strength. However, naturally, it is not necessarily limited to the annular structure. The wall thickness of the magnetic tube 123 should not be too thick and is generally within 0.5 mm. If the metal is too thick, the liquid on the surface will be located in an ineffective atomization region without reaching, resulting in a waste of resources. In addition, harmful substances may be generated due to the increase in the temperature of the metal.

[0030] As a preferred embodiment, the atomizing device 10 further includes a gasket 15. The gasket 15 is made of a silicone material. In order to prevent liquid leakage from occurring at the connection location between the suction nozzle 1151 and the support base 1163, the gasket 15 is sandwiched between the suction nozzle 1151 and the support base 1163.

[0031] The coil module 24 includes a holder 242 and an annular coil 243 wound in a ring shape. The holder 242 includes a straight tube 2421 and a first transverse plate 2422. The first transverse plate 2422 is fixed to the inner wall of one end of the straight tube 2421 that is separated from the suction nozzle 1151. Also, the straight tube 2421 and the first transverse plate 2422 surround the accommodation space 241 described above. The annular coil 243 is covered on the outer wall of the straight tube 2421. Also, the annular coil 243 is located between the outer wall of the straight tube 2421 and the inner wall of the engaging groove 211. The annular coil 243 is connected to the circuit board 22. The material of the annular coil 243 may be an enameled copper wire having good electrical conductivity and excellent surface insulation and heat resistance. Round wire or flat wire may be used for the enameled wire to save space. Also, for some high-end products, silver having a smaller electrical resistivity may be used as a conductor. In this case, since the internal resistance becomes smaller, it is less likely for the coil to generate heat. The annular coil 243 is wound around the holder 242.

[0032] Generally, a plastic material may be used for the holder 242, and a ferromagnetic metal material must not be used. The internal space of the holder 242 has a embossed structure. The accommodation space 241 described above is provided inside the holder 242. The accommodation space 241 is an alternating magnetic field region, and the magnetic metal member 12 to be heated needs to be located within this region. The annular coil 243 is wound around the holder 242 in a spiral shape, and its spiral pitch is substantially equal. An insulating layer is provided on the surface of the annular coil 243 to prevent short circuits.

[0033] The heating device 20 further includes a bottom case 25. The second base body 21 includes a power holder 212 and a heating case 213. The heating case 213 is annular. The circuit board 22, the power battery 23, and the power holder 212 are all located within the heating case 213. The power holder 212 includes a second horizontal plate 2121, a frame 2122, and a base 2123 that are provided to be connected in sequence from top to bottom. The base 2123 has an arrangement chamber 2124. The power battery 23 is fixed within the arrangement chamber 2124, and the circuit board 22 is fixed to the frame 2122. The frame 2122 is quadrilateral. Both the frame 2122 and the second horizontal plate 2121 can abut against the coil module 24. In this embodiment, the frame 2122 abuts against the coil module 24, and the bottom case 25 is attached to the heating case 213 and abuts against the base 2123. Also, the inner wall of the second horizontal plate 2121 and the heating case 213 surrounds the above-described engaging groove 211.

[0034] As a preferred embodiment, the heating device 20 further includes several temperature sensors 26. Several third through-holes 2125 are vertically formed in the second horizontal plate 2121. Also, several holding ports 2423 are vertically formed in the first horizontal plate 2422. One end of the temperature sensor 26 is fixed to the holding port 2423 and is located within the holding chamber 112, and the other end passes through the third through-hole 2125 and is then connected to the circuit board 22. The temperature sensor 26 can contact the magnetic metal member 12 within the atomizing device 10 and is used to detect the real-time temperature of the magnetic metal member 12 and feedback temperature information to the circuit board 22. Thereby, the temperature of the magnetic metal member 12 is controlled to avoid the temperature of the magnetic metal member 12 becoming excessively high. For the temperature sensor 26, a thermistor, or a thermocouple, or a temperature-sensitive metal material with good temperature sensitivity can be selected.

[0035] The heating device 20 is further provided with an air supply path 27. The power supply holder 212 and the heating case 213 are provided at intervals. The bottom case 25 is provided with several first air supply holes 251 penetrating therethrough. The second horizontal plate 2121 is further provided with several second air supply holes 2126 penetrating therethrough. The first horizontal plate 2422 is further provided with several third air supply holes 2424 penetrating therethrough. The first air supply holes 251, the interval between the power supply holder 212 and the heating case 213, the second air supply holes 2126, the third air supply holes 2424 and the holding chamber 112 communicate with each other in sequence. The first air supply holes 251, the interval between the power supply holder 212 and the heating case 213, the second air supply holes 2126 and the third air supply holes 2424 constitute the above-mentioned air supply path 27. That is, the external gas can enter the holding chamber 112 only after passing through the first air supply holes 251, the interval between the power supply holder 212 and the heating case 213, the second air supply holes 2126 and the third air supply holes 2424 in sequence.

[0036] The gas enters from the holding chamber 112 at the bottom, is blocked by the bottom of the liquid storage tank 113 and dispersed in the circumferential direction. The gas passes through the surface of the magnetic metal member 12 and is mixed with the atomized vapor heated and atomized by the magnetic metal member 12 to become an aerosol substance. Then, after passing through the first through hole 121, it enters the exhaust passage 111 and is inhaled by the user from the exhaust passage 111. The direction indicated by the arrow in FIG. 5 is the flow direction of the gas.

[0037] As a preferred embodiment, the bottom base 116 further includes a spacer 1165 and several connecting rods. Both the spacer 1165 and the connecting rods are located within the second through hole 1164. The spacer 1165 is provided at a distance from the magnetic metal member 12. One end of the connecting rod is connected to the outer wall of the spacer 1165, and the other end is connected to the inner wall of the second through hole 1164. Moreover, the bottom of the spacer 1165 abuts against the ceiling of the first transverse plate 2422. A communication hole 1166 is vertically formed through the spacer 1165. The communication hole 1166 communicates with the third air supply hole 2424. The role of the spacer 1165 is to prevent the liquid falling from the liquid guiding member 13 from flowing into the interior of the heating device 20 through the third air supply hole 2424 when using the atomization module used in the electromagnetic heating device. For the same reason, the external gas can enter the holding chamber 112 only after passing through the third air supply hole 2424 and the communication hole 1166.

[0038] As a preferred embodiment, the heating device 20 further includes a charging socket 28. The charging socket 28 is fixed to the bottom case 25. The charging socket 28 is connected to the circuit board 22 via a conducting wire for charging the power battery 23.

[0039] As a preferred embodiment, the heating device 20 further includes a seal block 29. The seal block 29 is fixed between the bottom case 25 and the power supply holder 212.

[0040] The operating principle of the atomization module used in the electromagnetic heating device is as follows.

[0041] The liquid storage tank 113 of the atomization device 10 is filled with liquid, and the upper end is sealed by the gasket 15. The liquid that requires atomization is stored in the liquid storage tank 113. A plurality of liquid supply holes 114 are opened in the bottom base 116 to communicate the liquid with the outside. Further, a liquid guiding member 13 is provided outside the liquid supply hole 114. The inside of the liquid guiding member 13 is provided with a void hole 131 that enables the storage and transmission of liquid. The inner wall of the liquid guiding member 13 is further provided with a magnetic metal member 12. The magnetic metal member 12 serves as a carrier material for electromagnetic induction heating.

[0042] The atomizing device 10 is partially inserted into the alternating magnetic field region of the heating device 20. When the control circuit detects an inhalation signal, the circuit board 22 starts operating, and an alternating magnetic field is generated in the annular coil 243. Then, the magnetic metal member 12 rapidly generates heat by generating eddy currents, and the heat evaporates the liquid on the liquid guiding member 13 into atomized vapor. Then, this is mixed with the air entering from the air supply path 27 to become an aerosol substance and is inhaled by the user. When the control circuit does not detect an inhalation signal, the circuit board 22 stops operating, and the magnetic metal member 12 does not generate heat.

[0043] The atomizing module used in the electromagnetic heating device in the present invention converts direct current into high-frequency and high-voltage current, and an alternating magnetic field is generated when the current passes through the annular coil 243. Then, when the magnetic field lines of the magnetic field pass through the magnetic metal member 12, a very large eddy current is generated, and the magnetic metal member 12 itself rapidly generates heat.

[0044] The atomizing device 10 and the heating device 20 adopt a separable structure. The heating device 20 is equipped with components such as a power battery 23 and a circuit board 22. Since the cost is high, it should be possible to charge and use it repeatedly. In contrast, for the atomizing device 10, the tobacco liquid inside has different flavors and belongs to consumables, and it also comes into contact with the human body. In addition, the internal tobacco liquid or the liquid guiding member 13 loses its function after long-term use. Therefore, the atomizing device 10 is a consumable and must be replaced with a new one when the internal tobacco liquid is used up.

[0045] The above embodiments are only preferred embodiments of the present invention and cannot limit the protection scope of the present invention. Any non-substantial modifications and replacements made by those skilled in the art based on the present invention all belong to the scope claimed by the present invention.
