The application provides an airflow heater, including drainage container and stack a plurality of granular heat-generating bodies in the drainage container, can be with the help of between the adjacent heat-generating body and the heat-generating body and drainage container inner wall between the structure clearance that forms naturally, as the air current passageway that the air feed flows through the drainage container. On the one hand, the air flow channel established based on the structural gap has higher tortuosity, so that the distance of the air flow passing through the drainage container can be prolonged, the heat exchange area is increased, and the air flow can pass through the drainage container in a state similar to vortex, thereby creating conditions for improving the heat exchange efficiency. On the other hand, the granular heating bodies are stacked in the drainage container to form the airflow heater, so that the manufacturing process is easy to realize, and the overall manufacturing cost of the heater is reduced.

Referring to fig. 1 and 2, an embodiment provides an airflow heater that can be installed in an airflow channel of a heating non-combustion atomization device to heat an airflow flowing through the airflow channel to a preset temperature to form a hot airflow; the air flow heater comprises a drainage container 10 and a plurality of heating bodies 20; the following is a detailed description.

Referring to fig. 1 and 2, the drainage container 10 is a generally cylindrical structure having a predetermined length, and includes a side wall portion 11 and two end wall portions 12; wherein the two end wall parts 12 are oppositely arranged at intervals along the length direction of the drainage container 10, and the side wall part 11 is arranged between the two end wall parts 12; the two sides of the side wall 11 extend to the corresponding end wall 12 and are enclosed around the end wall 12, so that the drainage container 10 is constructed to form a column-shaped structure with hollow inside; for convenience of distinction and description, the inner space of the drainage container 10 is defined as the accommodation space 10a.

Meanwhile, vent holes for communicating the accommodating space 10a are formed in both end wall portions 12; for convenience of distinction and description, the ventilation holes in the two end wall portions 12 are defined as an intake hole 10b and an exhaust hole 10c, respectively; wherein the air inlet holes 10b are used for air supply flow to enter the accommodating space 10a, and the air outlet holes 10c are used for air supply flow to exit the accommodating space 10a.

Referring to fig. 2, the heating elements 20 are in a sphere structure, and the plurality of heating elements 20 are filled and accommodated in the accommodating space 10a in a form similar to staggered stacking, and by utilizing the structural characteristics that the adjacent heating elements 20 are in point contact with each other and the heating elements 20 are in point contact with the inner wall of the drainage container 10, certain structural gaps exist or are kept between the adjacent heating elements 20 and between the heating elements 20 and the inner wall of the drainage container 10, and by utilizing the structural gaps, structural channels with high labyrinths and high tortuosity can be formed in the accommodating space 10 a; for convenience of distinction and description, the structural channel is defined as an air flow channel (not shown), and the air flow entering the accommodating space 10a from the air inlet hole 10b may flow out of the accommodating space 10a from the air outlet hole 10c along a path or direction defined by the air flow channel.

In some embodiments, the heating element 20 may be a spherical structure made of ferromagnetic material or alloy material containing iron, nickel, cobalt, titanium, etc., or a spherical structure made of inorganic nonmetallic material with ferromagnetic properties such as magnetized ceramic, carbon fiber, etc., or a spherical structure made of soft magnetic material. Suitably, the drainage container 10 may be made of a refractory material such as ceramic.

When the airflow heater is applied to an atomization device, an electromagnetic coil can be arranged around the periphery of the airflow heater (or the drainage container 10), and the electromagnetic coil is used for providing an alternating magnetic field environment for the heating body 20 and/or the drainage container 10, so that the heating body 20 and/or the drainage container 10 can generate heat under the action of the alternating magnetic field, and the flowing airflow is heated.

In other embodiments, the heating element 20 and the drainage container 10 may be made of electrothermal materials such as nichrome and ferrochrome, and when the airflow heater is applied to the atomization device, the drainage container 10 and a power supply assembly (for example, formed by combining and building a power supply, a power supply circuit, etc.) of the atomization device may be electrically connected; the current-supply assembly supplies power to the current-guiding container 10 to promote the current-guiding container 10 to generate heat, and then the heat is transferred to each heating body 20 by utilizing the structural contact relation between the current-guiding container 10 and the heating bodies 20, so that the current of air flows through the heating bodies 20 through the air flow channel to be heated to form hot air flow.

Based on this, with the plurality of spherical heat-generating bodies 20 stacked in the drainage container 10, an air flow passage having a high tortuosity and a complicated arrangement path or direction can be constructed in the accommodation space 10a by means of gaps between the adjacent heat-generating bodies 20 and between the heat-generating bodies 20 and the inner wall of the drainage container 10, so that the air flow passing through the drainage container 10 can flow through the heat-generating bodies 20 in a state similar to a vortex; on the one hand, compared with the existing straight-through air inlet mode, the air flow can perform sufficient and uniform heat exchange with the air flow heater, so that the heat exchange efficiency is effectively improved, and the air flow can be uniformly heated; on the other hand, compared with the prior art that the porous air inlet mode is adopted, the heating element 20 is arranged in the drainage container 10 to form an air flow channel for air flow, so that the manufacturing process is easier to realize, and the manufacturing and using cost of the air flow heater is reduced.

In another embodiment, the heating element 20 may be a granular structure with other regular or irregular geometric shapes, for example, a bar-shaped columnar structure with different lengths is adopted, and the plurality of heating elements 20 are randomly or randomly filled in the accommodating space 10a, or an air flow channel with complicated and high tortuosity can be formed.

In addition, the overall outline of the drainage container 10 may be adaptively adjusted according to the shape configuration of the internal space of the atomizing device (such as the trend and the cut-off shape of the airflow channel of the atomizing device itself), so that the airflow heater can be used as an intermediate communication member between the air inlet portion and the air outlet portion of the atomizing device; for example, the air inlet hole 10b and the air outlet hole 10c may be located in the drainage container 10 in a non-opposite or opposite manner.

In one embodiment, referring to fig. 2, the plurality of heating elements 20 are uniformly sized, namely: the outer diameters of the plurality of heating elements 20 are the same; therefore, when the heating elements 20 with uniform size are stabilized in the accommodating space 10, gaps between the adjacent heating elements 20 and between the heating elements 20 and the inner wall of the drainage container 10 are uniform, and gaps between the heating elements 20 exist in the accommodating space 10a in a layer-by-layer dislocation distribution mode, so that the tortuosity of airflow passing through the airflow heater is enhanced, and the sufficient and uniform heat exchange with the heating elements 20 (or the drainage container 10) is realized.

In one embodiment, referring to fig. 2, the outer dimensions of the heat generating body 20 are set to be larger than the apertures of the air inlet hole 10b and the air outlet hole 10c, for example, the outer diameter of the heat generating body 20 is set to be larger than the apertures of the air inlet hole 10b and the air outlet hole 10c; thus, the heat generating body 20 can be prevented from blocking the air inlet hole 10b or the air outlet hole 10c, or the heat generating body 20 leaks out from the air inlet hole 10b or the air outlet hole 10 c.

Referring to fig. 3 and 4 in conjunction with fig. 1 and 2, an atomization device is further provided according to an embodiment of the present application, including a main unit 30, a coil 40, and the airflow heater of the foregoing embodiment; the atomization device can provide an alternating magnetic field environment for the airflow heater by means of the coil 40, so that the heating body 20 heats under the action of the alternating magnetic field and heats the airflow flowing through the heating body, thereby baking and heating the medium to be atomized arranged in the atomization device by means of the formed airflow, and further promoting the medium to be atomized to generate smoke or release volatile substances.

In particular, the host 30 can be understood as a collection of relevant functional components constituting the outer profile of the atomizing device; for example, the host 30 may be built up from a combination of a housing, internal plumbing, a control module including a power source, and the like. The user can carry, use and operate the atomizing device by holding the main body 30; in general, the host 30 should be configured with a channel or structural space for air flow in and out; for example, an air inlet channel through which external air can enter the host machine, a heating atomization channel through which air can flow through by heating by an air flow heater or directly contact with a medium to be atomized, an air outlet channel through which aerosol mist (which can be understood to be a mixture of a substance generated or released by the medium to be atomized and air) can be discharged out of the host machine 30, and the like can be built up by means of an internal pipe assembly.

For convenience of distinction and description, referring to fig. 3 and 4, a channel or space for external air to enter the inside of the atomizing device in the main body 30 is defined as an inlet channel 30a, and a channel or space for aerosol mist to exit the atomizing device and an air flow heater to directly or indirectly heat the atomizing medium is defined as an outlet channel 30b.

The coil 40 is installed in the main unit 30 (e.g., at a position between the inlet channel 30a and the outlet channel 30 b), and is disposed around the air flow heater at the periphery of the air flow heater; the coil 40 may be electrically connected to a control module of the host 30, so as to generate an alternating magnetic field under the control of the control module, so that the heating element 20 (or the drainage container 10) generates heat due to the alternating magnetic field.

Therefore, when the atomization device works, the airflow can be heated by the airflow heater to form hot airflow, and the airflow can be fully heat-exchanged with the flowing airflow due to the high tortuosity of the path of the airflow passing through the airflow heater (namely, the airflow channel of the airflow heater), so that the airflow is uniformly heated to form hot airflow, and meanwhile, the beneficial condition can be created for reducing the power consumption of the whole atomization device.

In one embodiment, referring to fig. 3 and 4, the atomizing device further includes a sleeve 50, wherein the sleeve 50 is disposed in the main unit 30 and is in butt-joint communication with the air outlet channel 30b and the air inlet channel 30 a; the airflow heater is arranged in the sleeve 50 and is positioned at one end of the sleeve 50 adjacent to the air inlet channel 30 a; and the coil 40 is wound around the outside of the sleeve 50. In this way, the air flow heater, the coil 40, the air inlet channel 30a and the air outlet channel 30b can be structurally integrated by the sleeve 50, so as to ensure that the air flow heater can be stably fixed in the host 30. At the same time, the sleeve 50 can also be used for guiding the hot air flow and preventing heat from radiating, so as to create favorable conditions for improving the heat utilization rate.

In one embodiment, referring to fig. 3 and 4, at least a portion of the tubular space (e.g., other area except the airflow heater) or the air outlet channel 30b of the sleeve 50 is configured to accommodate a medium to be atomized, for example, when the medium to be atomized is a cigarette a, one end of the cigarette a may be inserted into the sleeve 50 via the air outlet channel 30b and be as close to the airflow heater as possible, so that the hot airflow generated by heating by the airflow heater can directly act on the cigarette a to cause the cigarette a to generate smoke.

It should be noted that, the "medium to be atomized" described herein may be solid medium materials such as medicinal materials and fragrances, semisolid medium materials such as medicinal paste and smoke paste, or liquid medium materials such as liquid medicine, physiological saline, liquid extract and tobacco tar, besides the cigarette a; typically, the medium to be atomized may be packaged in a shaped form from a wrapper or may be contained within a container (e.g., an atomizing cup) based on the form of the material.

In one embodiment, referring to fig. 3 and 4, the atomizing device further includes a support member 60, where the support member 60 is disposed in the sleeve 50 and abuts against a side of the drainage container 10 where the air outlet hole 10c is disposed, and is mainly used for supporting the medium to be atomized disposed in the atomizing device, so as to prevent the medium to be atomized from blocking or sealing the air outlet hole 10c of the drainage container 10, thereby ensuring that the air flow can smoothly pass through the air flow heater and act on the medium to be atomized. In particular, the support 60 may be a bracket structure or have a plurality of through holes disposed therethrough.

In other embodiments, the atomizing device provided in the embodiments of the present application may also adopt an electrothermal heating structure, that is: the coil 40 is omitted, and the control module of the host 30 is electrically connected with the air flow heater (for example, the drainage container 10) through the selection of the material of the air flow heater, and the air flow heater is powered on to cause the air flow heater to generate heat, so that the air flow passing through the air flow heater is heated. Reference is made specifically to the prior art and will not be described in detail herein.

The foregoing description of the utility model has been presented for purposes of illustration and description, and is not intended to be limiting. Several simple deductions, modifications or substitutions may also be made by a person skilled in the art to which the utility model pertains, based on the idea of the utility model.
