Detailed ways

The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

The core of the present invention is to provide a magnetic induction low-temperature baking smoking device that can evenly heat the cigarette 100.

Please refer to FIG. 1 and FIG. 2 , FIG. 1 is a cross-sectional view of the magnetic induction low-temperature baking smoking device provided by the present invention; FIG. 2 is an enlarged view of the heating head 300 in FIG. 1 .

A magnetic induction low-temperature baking tobacco utensil, comprising a heating head 300 and an electric rod assembly 400 for supplying power to the heating head 300; an electromagnetic heating sleeve 316 is installed inside the heating head 300 and is used to be fixedly mounted on the outside of a cigarette 100 and heat the cigarette 100; a magnetic induction coil 313 is surrounded by the electromagnetic heating sleeve 316, and the magnetic induction coil 313 is used to receive electric energy provided by the electric rod assembly 400 to generate a magnetic field; an electromagnetic heating body 312 is installed inside the electromagnetic heating sleeve 316 and is used to heat the cigarette 100.

It should be noted that the connection relationship between the heating head 300 and the electric rod assembly 400 can be detachable here. Of course, an integrated type can also be used when necessary. The only difference is that the detachable type only requires disassembly and assembly of a small part of the parts during maintenance, which saves time and effort. If an integrated type is used, if an internal circuit failure occurs, the entire smoking device must be replaced, which increases costs and causes waste.

The shape of the electromagnetic heating sleeve 316 here can be a straight tube or other shapes of tubes, such as an oblique tube, but the straight tube is more convenient in processing and installation; the material of the electromagnetic heating sleeve 316 here is a magnetic metal, such as iron, iron alloy and other materials. Iron alloy can be used here, because iron alloy is more common and easy to collect, and the alloy has greater strength and is not easy to deform. In order to adapt to the shape of the cigarette 100, a round tube can be used here. Of course, other shapes can also be used, such as a square tube, but the square tube cannot fit the cigarette 100 completely for heating, and the heating is uneven, so a round tube is used here.

A magnetic induction coil 313 is wound around the outside of the electromagnetic heating sleeve 316 in a spiral manner from one end of the electromagnetic heating sleeve 316 to the other end. The magnetic induction coil 313 here can be made of copper or other materials with good conductivity. Insulating materials such as sheaths can be installed on the outside of the coil to protect the wires. The electromagnetic coil generates a magnetic field by receiving the electric energy provided by the electric rod assembly 400. The magnetic field here is the same as the magnetic field of a bar magnet. The polarity of its two ends is related to the direction of the current. The relationship between the current direction and the magnetic pole can be determined by Ampere's law. According to Faraday's law of electromagnetic induction, the current direction here can be from top to bottom or from bottom to top. In order to facilitate the connection with the electric rod assembly 400, the current direction here adopts the current direction from bottom to top.

An electromagnetic heating body 312 is installed inside the electromagnetic heating sleeve 316, and the connection method can be a detachable connection. The shape of this electromagnetic heating body 312 can be a knife shape, or other shapes, such as a needle shape; preferably, its arrangement position can be the center position of the above-mentioned circular sleeve. Of course, it can also be eccentrically arranged. In order to heat the cigarette 100 more evenly, a needle-shaped electromagnetic heating needle is used here.

The magnetic induction low-temperature baking tobacco utensil provided in the above-mentioned embodiment uses the electric rod assembly 400 to power the magnetic induction coil 313 and generate a magnetic field. The electromagnetic heating body 312 and the electromagnetic heating sleeve 316 are placed therein to cut the magnetic flux lines, thereby generating an alternating current inside the object, causing the atoms inside the electromagnetic heating body 312 and the electromagnetic heating sleeve 316 to move irregularly at high speed, and the atoms collide and rub against each other to generate heat energy, thereby achieving the effect of heating the cigarette 100; that is, the cigarette 100 is heated both inside and outside at the same time, so that the cigarette 100 is heated more evenly.

Optionally, the electric rod assembly 400 includes a magnetic induction controller 410, a magnetic induction switch 420, and a detachable electrically connected power supply component 430; one end of the magnetic induction controller 410 is connected to the magnetic induction switch 420, and the other end is connected to the magnetic induction coil; the magnetic induction switch 420 is connected to the detachable electrically connected power supply component 430, and by adjusting the magnetic induction intensity, the electromagnetic heating tube and the electromagnetic heating needle are heated simultaneously by electromagnetic induction.

The electric rod assembly 400 also includes an electric rod shell, and the power supply component 430 is detachably connected to the electric rod shell, that is, power supply components 430 of different specifications can be selected to meet corresponding needs.

The most important structure in the power supply component 430 is the battery 431, which can be a lithium battery or other forms of battery 431, such as a dry cell battery. However, dry cells are non-recyclable batteries. In order to avoid waste of resources and pollution to the environment, a recyclable lithium battery is used here.

The electric rod shell is provided with a battery cavity 432 for placing the battery 431, and the lower end of the battery cavity 432 is provided with an electric rod back cover 433 for preventing the battery 431 from falling off. The electric rod back cover 433 is connected to the electric rod shell in a detachable manner, and the connection method here can be a threaded connection, of course, it can also be other connection methods, such as snap-on connection, etc.

During the heating process, the external electromagnetic induction coil 313 will be heated by the electromagnetic heating sleeve 316. In order to reduce the amount of heat received by the electromagnetic induction coil 313, a heat insulation layer 321D is provided for heat insulation.

A metal composite sleeve 310 may be installed inside the heating head 300 , and the metal composite sleeve 310 includes a metal main bracket 311 and a spiral button 315 installed on the upper end of the metal main bracket 311 , a magnetic induction coil 313 surrounds the outside of the metal main bracket 311 , and an electromagnetic heating sleeve 316 is installed inside the metal main bracket 311 .

It should be noted that the material of the metal main bracket 311 here can be copper, aluminum, alloy or other non-magnetic materials. In order to match the shape of the electromagnetic heating sleeve 316, the metal main bracket 311 here adopts a round tube shape. If a square shape is used in the above embodiment, the metal main bracket 311 here also adopts a square shape.

A slot 324 is installed at the bottom of the heating head 300, and the metal main bracket 311 can be installed on the slot 324 in a detachable manner. The connection method can be a threaded connection or other detachable connection methods, such as snap connection, but the threaded connection is more reliable; a spiral button 315 is installed at the upper end of the metal main bracket 311, and the spiral button 315 can be wrapped around the upper end of the metal main bracket 311. The spiral button 315 can increase friction and make it easier to disassemble and assemble.

The magnetic induction coil is changed from being wrapped around the outside of the electromagnetic heating sleeve 316 to being wrapped around the outside of the metal main bracket 311. The wrapping method is the same as the above-mentioned wrapping method and will not be repeated here. The electromagnetic heating sleeve 316 is installed inside the metal main bracket 311. The installation method can be a threaded connection. For example, a flange can be processed on the upper end of the electromagnetic heating sleeve 316, an external thread can be processed on the flange, and an internal thread can be processed on the inner ring of the upper end of the metal main bracket 311. The external thread and the internal thread are matched for connection.

In order to facilitate the disassembly and assembly of the electromagnetic heating sleeve 316, a position can be reserved above the thread to install a screw button, and the installation method is the same as the installation method of the screw button 315 on the above-mentioned metal main bracket 311.

The above-mentioned electromagnetic heating needle can be disc-shaped at the bottom, and a needle-shaped body is processed vertically upward in the center of the disc. The outer circumference of the disc is matched and connected with the inner circle of the metal main bracket 311. The connection method can be a threaded connection, specifically, an external thread is processed on the outer circumference of the disc, and an internal thread is processed on the inner circle of the metal main bracket 311, and the external thread is matched and connected with the internal thread.

Of course, in order to facilitate disassembly and assembly, a spiral knob can be processed vertically downward in the center of the disc.

In the above embodiment, a metal main bracket 311 is provided between the electromagnetic induction coil 313 and the electromagnetic heating sleeve 316 , which has a partial heat insulation effect and can reduce the heat received by the electromagnetic induction coil 313 , thereby extending the service life of the electromagnetic induction coil 313 .

In order to further protect the electromagnetic induction coil 313 , a protection mechanism is added outside the electromagnetic induction coil 313 . For example, a shield 314 is installed on the metal main bracket 311 . The shield 314 is used to fix and protect the electromagnetic induction coil 313 .

It should be noted that the shield 314 here can be a mesh structure, surrounding the magnetic induction coil 313. Of course, a fully enclosed structure can also be used, but the fully enclosed structure is not conducive to the heat dissipation of the magnetic induction coil 313, so the mesh structure is used.

The connection method between the shield 314 and the metal main bracket 311 can be a threaded connection or other connection methods, such as clamping, hinged, etc. The threaded connection method is convenient for disassembly and assembly and is more reliable, so a threaded connection is adopted here. Specifically, an external thread is processed at the outer ring of the upper end of the shield 314, and a flange is processed at the upper end of the metal main bracket 311. The spiral button 315 is installed on the flange, and a circular groove is processed on the flange so that the shield 314 can match the groove. An internal thread is processed on the inner ring of the lower end of the spiral button 315, and the external thread and the internal thread are matched and connected.

In order not to affect the magnetic field generated by the electromagnetic heating sleeve 316, the material of the shield 314 here can be non-magnetic materials such as copper, aluminum, and alloy.

In the above embodiment, the shield 314 is used to further protect and fix the electromagnetic induction coil 313 , thereby limiting the range of movement of the electromagnetic induction coil 313 .

In order to facilitate the disassembly and assembly of the components inside the heating head 300, the heating head 300 adopts a split structure.

For example, the heating head 300 is composed of a shell 321 and a base 322 , and the shell 321 and the base 322 are connected by threads.

The outer shell 321 of the heating head 300 can adopt a lower straight tube and an upper hemispherical structure to adapt to the internal parts. An air outlet is opened at the upper end of the hemisphere for smoke to be emitted. An air layer is arranged between the lower straight tube and the outermost end of the internal parts to provide insulation and avoid direct contact.

The connection between the housing 321 and the base 322 may be a threaded connection or a detachable connection such as a snap connection.

This embodiment adopts a split structure of the heating head 300, which can facilitate the disassembly and assembly of internal parts.

You can also get a different smoking experience by increasing the air intake.

For example, an air inlet 323 for increasing the air intake amount is provided on the base 322 , and an opening is provided at the bottom of the heating head 300 , and the air inlet 323 is connected to the opening.

The air inlet 323 can be opened at any part of the base 322. For air circulation, the embodiment of the present application can open the air inlet 323 on the periphery of the base 322. The shape of the air inlet 323 is square here. Of course, other shapes can also be used. As long as the shape does not hinder air circulation, it is included in the protection scope of this application.

At the bottom of the inner chamber of the heating head 300 , that is, at the upper part of the base 322 , there is an opening connected to the inner chamber of the heating head 300 , and the opening is connected to the above-mentioned air inlet 323 , that is, there is an air duct 321B on the base 322 connecting the opening and the air inlet 323 .

In this embodiment, the air intake volume is changed by adding the air inlet 323, and the mixing ratio of air and smoke is changed, which not only allows a different inhalation taste to be experienced, but also allows the cavity to be cooled by bringing in new cold air.

In order to further experience different smoking tastes, a valve 325 for adjusting the air intake volume may be installed in the air intake port 323 .

The shape of the valve 325 is a rectangular parallelepiped, and it can slide along the air inlet 323 perpendicular to the air inlet direction. For the convenience of adjustment, the valve 325 can be in a shape that protrudes from the periphery of the base 322. The position of the valve 325 can be adjusted by sliding it left and right by hand, thereby changing the air intake amount.

In this embodiment, the valve 325 is added to change the air intake volume to obtain different mixing ratios of air and smoke, so that different smoking tastes can be experienced.

On the basis of the above embodiment, the heating cavity may be further insulated.

For example, an air duct 321B is provided between the outer shell layer 321A and the inner wall 321C of the outer shell 321, an air inlet 323 of the air duct 321B is opened at the upper end of the heating head 300, and the air duct 321B is connected to the inner chamber of the heating head 300 through the bottom opening of the inner wall 321C.

It should be noted that the air duct 321B here forms a closed loop along the outer shell 321 and is connected to the outside through the air inlet 323, and is connected to the inner chamber of the main heating chamber 320 through the opening at the bottom of the inner wall 321C. The opening is as large as possible to allow excess gas to circulate.

During the suction process, the pressure in the inner cavity of the heating head 300 decreases, and the outside air flows into the airway 321B from the above-mentioned air inlet 323, and then enters the inner cavity of the main heating cavity 320 from the airway 321B. The outside air enters the inner chamber of the main heating cavity 320 and flows out to the port of the heating head 300 together with the smoke after baking; since the air in the airway 321B is circulating, the air carrying heat is continuously discharged, which reduces the heat inside the airway 321B, reduces the heat of the main heating cavity 320, and avoids scalding.

On the basis of the above embodiment, in order to further reduce the heat exposure of the outer shell layer 321A, a heat insulation layer 321D may be provided between the outer shell layer 321A and the air duct 321B.

Here, the heat insulation layer 321D may be made of traditional materials such as glass fiber, silicate, etc., or may be made of new heat insulation materials such as aerogel felt, etc.

In a specific embodiment, please refer to Figure 5, the electromagnetic heating sleeve 316- is a tubular structure, including a second heating tube 316A, a second connecting thread 316B arranged at one end of the second heating tube 316A, and a second screw button 316C arranged at the end of the second connecting thread 316B.

In addition, please refer to FIG6 , the electromagnetic heating body 312 includes a first columnar heating tube 312A, a first connecting thread 312B connected to the lower part of the first heating tube 312A, and a first screw button 312C disposed on the other side of the first connecting thread 312B. By holding and twisting the first screw button 312C, the electromagnetic heating body 312 can be rotated relative to the metal main bracket 311, thereby being separated or connected.

The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
