Description

Technical Field

[0001] This invention relates to the field of electronic cigarettes, and more specifically to an atomizing component, an atomizer, and an electronic atomizing device. Background Technology

[0002] With increased publicity about the harmful effects of traditional cigarettes, more and more smokers are gradually changing their habits. Electronic cigarettes are mainly used to replace traditional cigarettes. Their main working principle is to use an atomizer to vaporize non-toxic e-liquid into smoke, giving smokers a similar stimulating sensation to cigarettes.

[0003] Currently, electronic cigarette atomizers heat and atomize e-liquid through the heating element of the atomizing core to form smoke. The heating element comes in various forms, generally including a ceramic substrate, a heating wire, and connecting terminals. The heating wire is wound around the ceramic substrate, and the connecting terminals are respectively located at both ends of the ceramic substrate and are electrically connected to the heating wire. The ceramic substrate has hollow micropores, and the connecting terminals include terminal through holes that mate with the hollow micropores.

[0004] However, the aforementioned heating components have the following drawbacks:

[0005] 1. Resistance heating method is inefficient, consumes a lot of electricity, and produces smoke slowly;

[0006] 2. The structure is complex, the cost is high, and it is not easy to automate production;

[0007] 3. The need for wires for electrical connection with the heating element and the large surface area of ​​the heating element result in slow heating speed;

[0008] 4. The heating wire is prone to breakage and has a short service life;

[0009] 5. The resistance wire is prone to moving on the surface of the conductive liquid, resulting in uneven pitch, uneven heating, and poor taste.

[0010] Meanwhile, some heating elements are metal sheets that generate eddy currents through electromagnetic induction, with a guide on their surface to direct the smoke to the metal sheet and heat it to form smoke; however, the above-mentioned heating elements have the following disadvantages:

[0011] 1. Low heating efficiency and insufficient smoke generation;

[0012] 2. The e-liquid is prone to exploding upon contact with the metal plate, which can damage the e-cigarette and generate noise.

[0013] 3. There are problems with the electromagnetic coil heating up and electromagnetic radiation. Summary of the Invention

[0014] In view of the above-mentioned defects in existing technologies, the present invention provides an atomizing component, atomizer, and electronic atomizing device, which solves the problems of low heating efficiency, high noise, and electromagnetic radiation in existing technologies.

[0015] Firstly, to solve the aforementioned technical problems, an atomizing component is provided, comprising:

[0016] The support has a through atomizing channel in the center and at least one liquid inlet channel on its side that connects the atomizing channel and the outside of the support.

[0017] A magnetic heating tube made of porous metal is disposed in the atomization channel and is used to draw in the liquid matrix entering the atomization channel from the liquid inlet channel;

[0018] An electromagnetic coil made of porous metal is placed inside a support and used to heat the magnetic heating tube, so that the heated liquid matrix is ​​atomized and introduced into the magnetic heating tube.

[0019] An electromagnetic shielding tube made of porous metal is located inside a support and surrounds the outer periphery of the electromagnetic coil.

[0020] Furthermore, the porous metal is a metal felt or a foam metal.

[0021] Furthermore, the atomizing channel includes an air outlet and an atomizing chamber that are connected vertically, and the magnetic heating tube is disposed in the atomizing chamber; the support also has an annular cavity surrounding the atomizing cavity, and the electromagnetic coil and the electromagnetic shielding tube are both disposed in the annular cavity. The liquid inlet channel connects the annular cavity and the atomizing cavity in sequence, and the electromagnetic shielding tube has a through hole at the position corresponding to the liquid inlet channel. The electromagnetic coil is a spiral coil with a gap so that the liquid matrix enters the atomizing cavity after passing through the gap.

[0022] Furthermore, the lower end of the annular cavity is an opening, and the inner and outer circumferential surfaces of the electromagnetic coil abut against the inner circumferential surface of the annular cavity and the inner circumferential surface of the electromagnetic shielding tube, respectively, to close the opening.

[0023] Furthermore, the atomizing component also includes a non-metallic oil guide body, which is fitted around the outer periphery of the magnetic heating tube to guide the liquid matrix flowing in from the liquid inlet channel to the magnetic heating tube.

[0024] Furthermore, the atomizing component also includes a cylindrical non-metallic fixing member, the magnetic heating tube is fitted inside the non-metallic fixing member, and the non-metallic fixing member has a through hole at the position corresponding to the liquid inlet channel.

[0025] In a second aspect, the present invention also provides an atomizer comprising the atomizing components as described in any of the preceding claims.

[0026] Furthermore, the atomizer also includes an oil tank with an air outlet and a base located at the lower end of the oil tank. The atomizing component is located at the center of the oil tank, and the upper end of the bracket is fixed inside the air outlet, while the lower end is inserted into the base. The oil tank, the base, and the atomizing component together form an oil storage chamber for storing oil, and the liquid inlet channel communicates with the oil storage chamber. The base is also provided with at least one air inlet hole communicating with the atomizing chamber, and the base is also provided with a positive electrode spring and a negative electrode spring connected to the two ends of the electromagnetic coil, respectively.

[0027] Furthermore, the base is also provided with at least one oil-absorbing component for absorbing the liquid matrix that falls into the base from the atomization chamber.

[0028] Thirdly, the present invention also provides an electronic atomizing device, including a main unit for powering an atomizer, and an atomizer disposed on the upper end of the main unit as described in any of the above claims. The main unit contains a circuit board and a battery electrically connected to the circuit board. The circuit board has two positive pins and a negative pin that are electrically connected to a positive electrode spring and a negative electrode spring, respectively.

[0029] The present invention has the following beneficial effects:

[0030] The atomizing component of this invention employs a porous metal magnetic heating tube with a large number of directional or random pores diffusely distributed inside. This tube primarily functions to absorb liquid and induce heating, enabling the electromagnetic coil to induced heat the component. The regularly or irregularly distributed pores on the tube wall facilitate heat concentration, improving heating efficiency and enabling rapid heating. The electromagnetic coil, being a porous metal coil, generates less heat due to its porous structure, effectively reducing the coil's heating effect. Furthermore, the porous metal electromagnetic shielding tube, by surrounding the electromagnetic coil, prevents magnetic propagation outwards, reducing electromagnetic radiation. Simultaneously, the porous structure also provides noise reduction, solving the problems of low heating efficiency, high noise, and electromagnetic radiation in existing designs.

[0031] In addition, when the liquid matrix enters the atomizing component through the liquid inlet channel, it first enters the annular cavity and comes into contact with the electromagnetic coil. Of course, in the field of electronic cigarettes, e-liquid is non-conductive, so the liquid matrix can be used to cool the electromagnetic coil to a certain extent. The lower end of the annular cavity is open, which facilitates the assembly of the electromagnetic shielding tube and the electromagnetic coil. However, in order to prevent the liquid matrix from flowing down from the secondary opening, the inner and outer circumferences of the electromagnetic coil are respectively in contact with the walls of the annular cavity and the electromagnetic shielding tube to achieve the purpose of sealing. The overall structure is simple and reliable.

[0032] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and will become apparent from the description or may be learned by practice of the invention. Attached Figure Description

Obviously, the described embodiments are only some, not all, of the embodiments of the present invention.

[0042] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the invention. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0043] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0044] Example 1

[0045] like Figure 1 As shown in the figure, the atomizing component 100 shown in this embodiment includes a bracket 1, a magnetic heating tube 2, an electromagnetic coil 3, and an electromagnetic shielding tube 4.

[0046] The support 1 has a vertically penetrating atomizing channel 10 at its center, which serves as a cavity for atomizing the liquid matrix and allows the atomized smoke to flow upward under suction. At least one liquid inlet channel 11 is provided on the side of the support, connecting the atomizing channel 10 and the outside of the support, so as to introduce the liquid matrix located outside the support into the atomizing channel. The more liquid inlet channels there are, the more liquid matrix outside the support is introduced into the atomizing channel and the faster the efficiency. When there are at least two liquid inlet channels 11, the at least two liquid inlet channels 11 are arranged in a ring array on the support to ensure the liquid inlet efficiency in each direction, thereby achieving uniform liquid inlet in each liquid inlet channel.

[0047] Furthermore, the magnetic heating tube 2, the electromagnetic coil 3, and the electromagnetic shielding tube 4 are all made of porous metal, meaning that a large number of directional or random pores are diffusely distributed inside all three. The magnetic heating tube 2 is located inside the atomization channel 10 and uses its pores to draw in the liquid matrix entering the atomization channel 10 from the liquid inlet channel. In practice, the magnetic heating tube seals the inner opening of the liquid inlet channel, so that the liquid matrix can only flow onto the magnetic heating tube and be drawn in. The electromagnetic coil 3 is located inside the support 1 and surrounds the magnetic heating tube, placing the magnetic heating tube in the electromagnetic field in the middle of the electromagnetic coil. Under the action of the electromagnetic field, eddy currents are generated and the magnetic heating tube is heated, so that the liquid matrix introduced into the magnetic heating tube is atomized after the magnetic heating tube is heated. During the atomization process, the fluidity of the liquid matrix in the magnetic heating tube can be improved, thereby ensuring the atomization effect of the liquid matrix in the magnetic heating tube. The atomized aerosol has a good taste consistency. The electromagnetic shielding tube 4 is located inside the support 1 and surrounds the outer periphery of the electromagnetic coil 3.

[0048] In the above-mentioned magnetic heating tube made of porous metal, a large number of directional or random micropores are diffusely distributed inside. It firstly has the function of liquid absorption and induction heating, realizing the induction heating of the electromagnetic coil. The regular or irregular distribution of pores on the column wall helps to concentrate heat, improve heating efficiency and achieve rapid heating. The electromagnetic coil is a porous metal coil. Due to the presence of pores, it generates less heat, thus effectively reducing the heating of the electromagnetic coil. The electromagnetic shielding tube made of porous metal, by wrapping around the outside of the electromagnetic coil, can prevent the magnetic field from propagating outward and reduce electromagnetic radiation. At the same time, the porous structure can also play a role in noise reduction.

[0049] Preferably, the atomizing channel 10 includes an air outlet 12 and an atomizing chamber 13 connected vertically. The magnetic heating tube 2 is disposed within the atomizing chamber 13, while the liquid inlet channel surrounds and communicates with the atomizing chamber 13 to introduce the liquid matrix into the atomizing chamber for atomization. The air outlet is used as the outflow channel after atomization. The support 1 also has an annular cavity 14 that surrounds and is spaced apart from the atomizing chamber 13. The electromagnetic coil 3 and the electromagnetic shielding tube 4 are disposed inside the annular cavity 14 from the inside out. The liquid inlet channel 10 connects the annular cavity 14 and the atomizing chamber 13 in sequence, that is, the liquid inlet channel moves radially forward. The support is then penetrated, and the electromagnetic shielding tube 4 is provided with a through hole 41 at the position corresponding to the liquid inlet channel 10 for the inflow of liquid matrix. The electromagnetic coil 3 is a spiral coil with a gap so that the liquid matrix enters the atomization chamber 13 after passing through the gap. That is, the upper and lower ends of the electromagnetic coil 3 and the electromagnetic shielding tube are located above and below the liquid inlet channel, respectively. In the above, the atomization chamber and the annular chamber provided on the support are used to fix the magnetic heating tube, the electromagnetic coil and the electromagnetic shielding tube, respectively, and assemble them into an integral atomization assembly for use. The overall structure is simple and easy to assemble and disassemble.

[0050] Preferably, to facilitate the installation of the electromagnetic coil and electromagnetic shielding tube, the lower end of the annular cavity 14 is designed as an opening, allowing the electromagnetic coil and electromagnetic shielding tube to be installed into the annular cavity from bottom to top through the opening. To prevent the liquid matrix entering the annular cavity from flowing downwards from its opening, the inner and outer circumferential surfaces of the electromagnetic coil 3 are respectively made to abut against the inner circumferential surfaces of the annular cavity 14 and the electromagnetic shielding tube 4, thus using the electromagnetic coil to achieve the sealing purpose. The liquid matrix flows forward through the gaps between them. The overall structure is simple and reliable, reducing the need for additional sealing components. During assembly, to facilitate the installation of the electromagnetic coil and electromagnetic shielding tube into the annular cavity, they are generally fitted together first and then installed into the annular cavity together, avoiding the inconvenience of installing the other component after the first one is installed due to their abutting relationship.

[0051] Preferably, the atomizing component 100 further includes a non-metallic oil guide body 5, which is fitted around the outer periphery of the magnetic heating tube 2. This oil guide body has the ability to guide and lock in oil, so as to guide the liquid matrix flowing in from the liquid inlet channel to the magnetic heating tube. Thus, by using the oil guide body to absorb oil and then guide and disperse the oil to the entire magnetic heating tube, the oil guiding efficiency and atomization effect can be effectively improved. The oil guide body is non-metallic, so it does not absorb magnetism or be induced to heat, which is beneficial to the concentration of magnetism and improves the heating efficiency of the magnetic heating tube. In addition, the oil guide body also plays a role in supporting and fixing the magnetic heating tube. Generally speaking, the magnetic heating tube has a certain degree of flexibility, so a support is needed to support it.

[0052] In some alternative implementations, the porous metal can preferably be a metal felt or a foam metal; wherein, the metal felt is formed by weaving multiple metal fibers, so that the metal felt body has multiple weave holes, which not only serve to guide the liquid, but also allow the suction airflow to carry out the aerosol in the weave holes during the suction process, further ensuring the taste of the aerosol; the foam metal has multiple foam pores (i.e., the fine pores and / or micro pores mentioned above), the diameter of which can reach the millimeter level, and the foam pores on the foam metal are almost or all interconnected, which can also achieve the function of guiding the liquid and allow the aerosol on the foam metal to be carried out as much as possible.

[0053] In other embodiments, the oil guide is made of cotton.

[0054] Example 2

[0055] like Figure 2 As shown, the atomizing component 100 shown in this embodiment has a structure that is basically the same as that shown in Embodiment 1. The difference is that there is no oil guide body in this embodiment. However, the atomizing component in this embodiment also includes a cylindrical non-metallic fixing member 6. The magnetic heating tube 2 is fitted into the non-metallic fixing member 6, which plays a supporting and fixing role for the magnetic heating tube. The non-metallic fixing member 6 has a through hole 61 at the position corresponding to the liquid inlet channel 11. That is, this embodiment only uses the magnetic heating tube itself for liquid guiding and heating. The liquid guiding efficiency is slightly lower than that of the structure in Embodiment 1 that uses an oil guide body.

[0056] In other embodiments, the non-metallic fastener is made of silicone.

[0057] Example 3

[0058] like Figure 3 As shown in Figure 4, the atomizer 200 shown in this embodiment includes the atomizing component 100 as described in Embodiment 1 or Embodiment 2.

[0059] In this embodiment, the atomizer also includes an oil tank 7 with an air outlet 71 and a base 72 located at the lower end of the oil tank 7. The atomizing component 100 is located at the center of the oil tank 7, and the upper end of the bracket 1 is fixed inside the air outlet 71, while the lower end is inserted into the base 72. An oil storage chamber 73 for storing liquid matrix is ​​formed between the oil tank 7, the base 72, and the atomizing component 100. The liquid inlet channel 11 communicates with the oil storage chamber 73 to introduce the liquid matrix in the oil storage chamber into the atomizing chamber for atomization. The base 72 is also provided with at least one air inlet 74 communicating with the atomizing chamber 13 to realize gas flow when inhaling. The base 72 is also provided with a positive electrode spring needle 75 and a negative electrode spring needle 76 respectively connected to the two ends of the electromagnetic coil 3.

[0060] In this embodiment, the base 72 is also provided with at least one oil-absorbing component 77 for absorbing the liquid matrix that falls into the base from the atomizing chamber 13.

[0061] In other embodiments, the oil-absorbing element is made of porous metal.

[0062] Example 4

[0063] like Figure 5 As shown in Figure 6, this embodiment of an electronic atomizing device includes a main unit 300 that powers the atomizer 200, and an atomizer 200 as described in Embodiment 3, which is fitted onto the upper part of the main unit. The main unit 300 contains a circuit board 301 and a battery 302 electrically connected to the circuit board 301. The circuit board 301 has a positive terminal 303 and a negative terminal 304, both of which extend upward out of the main unit. The upper end of the positive terminal is electrically connected to the positive terminal spring 75 after contacting it, and the upper end of the negative terminal is electrically connected to the negative terminal spring 76 after contacting it, so as to use the battery to power the electromagnetic coil in the atomizer. The circuit board is used to control the power supply and charging operation. Of course, a push switch and a charging interface (not shown in the figure) are provided on the circuit board to realize the power supply control and battery charging.

[0064] Of course, in order to allow air to enter through the air intake, an inlet 305 connected to the air intake 74 is also provided on the wall of the main unit 300.

[0065] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should all be covered within the scope of protection of the present invention; therefore, the scope of protection of the present invention should be determined by the scope of the claims.
