Background Art

An aerosol generating device is an electronic transmission system that controls the working state and smoke output through control circuits and atomizing elements for user use.

Existing aerosol generating devices usually use a single liquid storage chamber and a single atomizing core. The aerosol generating matrix in the liquid storage chamber is guided to the atomizing core through the lower liquid channel and heated and atomized by the atomizing core. The aerosol generating matrix is composed of a variety of components with different boiling points and volatility characteristics, but the atomization conditions are the same, so it is difficult to effectively atomize each component at the same time to improve the taste.

In order to solve the above problems, those skilled in the art have proposed a solution of dual liquid storage chambers and dual atomization cores. The dual liquid storage chambers store aerosol-generating matrices with different boiling points, and each atomization core corresponds to a liquid storage chamber. The aerosols heated and atomized by the dual atomization cores are mixed and then reach the user's mouth through the air outlet channel. However, this structure is large in size and the user experience is not good.

Another aspect of the embodiments of the present disclosure provides an atomizer core 10 , please refer to FIGS. 2 to 11 , the atomizer core 10 includes a liquid-conducting liquid 11 and a heating element 12 .

The liquid-conducting liquid 11 includes a plurality of through holes and an atomizing surface 11a and a liquid absorbing surface 11b arranged opposite to each other. The through holes penetrate the liquid absorbing surface 11b and the atomizing surface 11a, and are used to guide the aerosol-generating matrix from the liquid absorbing surface 11b to the atomizing surface 11a. The heating element 12 is arranged on the atomizing surface 11a. The heating element 12 includes a first electrode 121, a second electrode 122 and at least two heating units 123. At least two heating units 123 are arranged at intervals and connected between the first electrode 121 and the second electrode 122 in parallel or in series. The atomizing core 10 is divided into a first atomizing area and a second atomizing area corresponding to the at least two heating units 123. The first atomizing area is not connected to the second atomizing area liquid.

The atomizing surface 11 a and the liquid absorbing surface 11 b of the liquid guiding liquid 11 are arranged opposite to each other, which is beneficial for guiding the aerosol-generating matrix to the atomizing surface 11 a of the liquid guiding liquid 11 through the liquid absorbing surface 11 b of the liquid guiding liquid 11 .

Exemplarily, referring to Figures 9 to 11, the atomizer core 10 includes a liquid-conducting body 11 and a heating element 12, an atomizing surface 11a and a liquid-absorbing surface 11b are disposed on opposite sides of the liquid-conducting body 11, the heating element 12 is disposed on the atomizing surface 11a, and the heating element 12 can generate heat when powered on.

The atomizing core 10 blocks the flow of the aerosol generating substrate in the first liquid storage chamber 100 b and the second liquid storage chamber 100 c , that is, the aerosol generating substrate does not directly flow into the atomizing chamber 100 d of the atomizer 100 .

In some embodiments, the liquid-conducting material 11 is a porous material such as ceramics to form a cubic structure for absorbing aerosol to generate a matrix.

A plurality of micropores are formed in the liquid guiding liquid 11, and the micropores can guide the aerosol generating matrix from the liquid absorbing surface 11b to the atomizing surface 11a. The heating element 12 is arranged on the atomizing surface 11a, that is, the liquid absorbing surface 11b is used to absorb the aerosol generating matrix, that is, the aerosol generating matrix in the liquid storage chamber can flow to the liquid absorbing surface 11b, and the aerosol generating matrix is guided to the atomizing surface 11a under the capillary force of the micropores, and the heating element 12 heats and atomizes the aerosol generating matrix to form an aerosol.

In some other embodiments, the material of the liquid-conducting body 11 is glass.

Referring to FIG. 10 and FIG. 11 , the heating element 12 includes a first electrode 121, a second electrode 122, and at least two heating units 123. The at least two heating units 123 are arranged at intervals and connected in parallel or in series between the first electrode 121 and the second electrode 122. That is, the heating units 123 can be connected in parallel or in series between the first electrode 121 and the second electrode 122, or some of the heating units 123 can be connected in parallel, and the other heating units 123 can be connected in series between the first electrode 121 and the second electrode 122.

For example, when the number of the heating units 123 is two, the two heating units 123 can be connected in parallel or in series between the first electrode 121 and the second electrode 122; when the number of the heating units 123 is three, two of the heating units 123 can be connected in parallel or in series between the first electrode 121 and the second electrode 122. After being connected in parallel, the first electrode 121 and the second electrode 122 are connected in series with another heating unit 123 .

One of the first electrode 121 and the second electrode 122 is a positive electrode, and the other is a negative electrode.

That is to say, each heating unit 123 shares the positive and negative electrodes, which is convenient for electrical connection and control, is conducive to miniaturization of the atomizer core 10, and simplifies the coating process.

The heating powers of the heating units 123 may be the same or different. The heating powers of the heating units 123 may be controlled to be different.

Each heating unit 123 can work simultaneously, or can work in different time periods according to needs, that is, each heating unit 123 can be controlled in a working state and a non-working state respectively.

Of course, the working time of each heating unit 123 can also be controlled separately.

The atomizer core 10 is divided into a first atomization area and a second atomization area corresponding to at least two heating units 123, and the first atomization area is not connected to the second atomization area by liquid. That is, the first atomization area corresponds to at least one heating unit 123, and the second atomization area corresponds to at least one heating unit 123.

The first atomization zone is not in liquid communication with the second atomization zone, that is, the aerosol-generating substrates between the first atomization zone and the second atomization zone do not flow through each other.

It should be noted that, the atomizer core 10 is not limited to only including the first atomization area and the second atomization area. The atomizer core 10 may also include other atomization areas, such as a third atomization area.

The atomizing core 10 provided in the embodiment of the present disclosure includes a liquid guiding surface 11 and a heating element 12. The liquid guiding surface 11 includes an atomizing surface 11a, a liquid absorbing surface 11b and a through hole penetrating the atomizing surface 11a and the liquid absorbing surface 11b, respectively, and the aerosol generating substrate can be guided from the liquid absorbing surface 11b to the atomizing surface 11a through the through hole. The heating element 12 is arranged on the atomizing surface 11a, that is, the liquid absorbing surface 11b is used to absorb the aerosol generating substrate, and the aerosol generating substrate can be guided from the liquid absorbing surface 11b to the atomizing surface 11a. The heating element 12 heats and atomizes the aerosol generating substrate to generate an aerosol. In addition, by setting the heating element 12 to include a first electrode 121, a second electrode 122 and at least two heating units 123, at least two heating units 123 are arranged at intervals and connected between the first electrode 121 and the second electrode 122 in parallel or in series, that is, each heating unit 123 can share the first electrode 121 and the second electrode 122, which is conducive to the miniaturization of the atomizer core 10 structure and simplifies the coating process. In addition, by dividing the atomizer core 10 into a first atomization zone and a second atomization zone corresponding to at least two heating units 123, the first atomization zone and the second atomization zone are not connected by liquid, that is, the atomizer core 10 can heat and atomize the aerosol generating substrate in different liquid storage chambers through the first atomization zone and the second atomization zone. Compared with the technical solution of one-to-one correspondence between multiple atomizer cores 10 and multiple liquid storage chambers, the atomizer core 10 of the embodiment of the present disclosure can heat and atomize the aerosol generating substrate in multiple liquid storage chambers respectively, which is conducive to the miniaturization of the aerosol generating device.

In the related art, the aerosol generating matrix is composed of a mixture of components with different boiling points. The temperature of the aerosol generating matrix during atomization is between the lowest boiling point and the highest boiling point of each component, resulting in insufficient atomization of some high-boiling point substances, and the sensory flavor of the high-boiling point components is not obvious, resulting in poor atomization effect and poor taste.

The atomizer core 10 provided in the embodiment of the present disclosure can be used to heat and atomize components with different boiling points by setting the heating power of each heating unit 123 to be different, thereby improving the atomization effect of the aerosol generation matrix and improving the taste.

It should be noted that there are many ways to achieve liquid disconnection between the first atomization zone and the second atomization zone. In some embodiments, the liquid guiding agent 11 is a dense matrix, and the through holes are independent holes. By setting the liquid guiding agent 11 to be made of a dense matrix, and the through holes are independent holes, that is, the liquids between the through holes are not connected, that is, the aerosol generating matrix between the through holes will not flow with each other. In this way, the aerosol generating matrix can only be guided from the liquid absorption surface 11b to the atomization surface 11a through the through holes, and will not flow from the first atomization area to the second atomization area.

It should be noted that the type of dense matrix is not limited here. Exemplarily, the material of the liquid-conducting liquid 11 is dense ceramic or glass.

In other embodiments, the through holes are disordered holes, and a dense partition layer 14 is provided between the first atomization zone and the second atomization zone. The dense partition layer 14 is used to isolate the through holes of the first atomization zone and the second atomization zone from being connected.

The through holes are disordered holes, for example, a plurality of micropores formed in the liquid guiding liquid 11, and the micropores can guide the aerosol generating matrix from the liquid absorption surface 11b to the atomization surface 11a, and the heating element 12 is arranged on the atomization surface 11a, that is, the liquid absorption surface 11b is used to absorb the aerosol generating matrix, that is, the aerosol generating matrix in the liquid storage cavity can flow to the liquid absorption surface 11b, and the aerosol generating matrix is guided to the atomization surface 11a under the capillary force of the micropores, and the heating element 12 heats and atomizes the aerosol generating matrix to form an aerosol.

A dense partition 14 is provided between the first atomization zone and the second atomization zone, and the dense partition 14 is used to isolate the through-holes of the first atomization zone and the second atomization zone from being connected, that is, the aerosol-generating matrix of the first atomization zone will not flow to the second atomization zone.

In some embodiments, the disordered pores are formed by pore formers when the ceramic or glass is sintered.

The pore former is, for example, an additive that increases the pore structure in the matrix material, and is generally a substance that is easily decomposed into gas. For example, by adding the pore former to the matrix material, and then sintering to decompose the pore former into gas, the gas overflows from the matrix material to generate disordered pores.

In some embodiments, at least two heating units 123 are connected in parallel. The atomizing surface 11a has a length direction and a width direction, at least two heating units 123 extend along the width direction, and the first electrode 121 and the second electrode 122 at least partially extend along the length direction.

That is to say, each heating unit 123 extends in the width direction, and each heating unit 123 is arranged in the length direction. By setting at least part of the first electrode 121 and the second electrode 122 to extend in the length direction, it is beneficial for each heating unit 123 to share the first electrode 121 and the second electrode 122, and a reasonable layout makes the structure of the atomizer core 10 compact, which is beneficial to the miniaturization of the atomizer core 10 and simplifies the coating process.

In some embodiments, the first electrode 121 and the second electrode 122 are both L-shaped and include a first section and a second section. The first section of the first electrode 121 and the first section of the second electrode 122 are respectively located on both sides of the length direction of the atomized surface 11a. The second section of the first electrode 121 and the second section of the second electrode 122 are respectively located on both sides of the width direction of the atomized surface 11a.

By configuring the first electrode 121 and the second electrode 122 to be L-shaped, the first electrode 121 and the second electrode 122 each include a first segment and a second segment.

The first section of the first electrode 121 and the first section of the second electrode 122 are respectively located on both sides of the length direction of the atomizing surface 11a. The second section of the first electrode 121 and the second section of the second electrode 122 are respectively located on both sides of the width direction of the atomizing surface 11a. Since each heating unit 123 extends in the width direction, the two ends of each heating unit 123 are respectively connected to the second section of the first electrode 121 and the second section of the second electrode 122. By locating the first section of the first electrode 121 and the first section of the second electrode 122 on both sides of the length direction of the atomizing surface 11a, the space of the atomizing surface 11a in the length direction can be fully utilized, so that the power supply component is electrically connected to the first electrode 121 and the second electrode 122 through the first section of the first electrode 121 and the first section of the second electrode 122. In addition, this layout method can provide space for each heating unit 123 in the width direction of the atomizing surface 11a as much as possible, which is conducive to improving the heating capacity of each heating unit 123. The size in the width direction of the atomizing surface 11a (i.e., the size of each heating unit 123 in the extension direction, or the length of each heating unit 123) is reasonably arranged, so that the structure of the atomizing core 10 is compact, which is conducive to miniaturization of the atomizing core 10 and simplifies the coating process.

In some embodiments, the width of the first segment of the first electrode 121 is greater than the width of the second segment thereof. The width of the first segment of the second electrode 122 is greater than the width of the second segment thereof. The aspect ratio of at least two heating units 123 is greater than 2.

That is to say, by setting the width of the first electrode 121 in the length direction of the atomizing surface 11a to be greater than its width in the width direction of the atomizing surface 11a, it is further beneficial to increase the size of each heating unit 123 in the width direction of the atomizing surface 11a, and can ensure that the width of the first section of the first electrode 121 is large enough, thereby ensuring the reliability of the electrical connection with the power supply component.

By setting the width of the second electrode 122 in the length direction of the atomizing surface 11a to be greater than its width in the width direction of the atomizing surface 11a, it is further beneficial to increase the size of each heating unit 123 in the width direction of the atomizing surface 11a, and can ensure that the width of the first section of the second electrode 122 is large enough, thereby ensuring the reliability of the electrical connection with the power supply component.

The aspect ratio of at least two heating units 123 is greater than 2, that is, the aspect ratio of each heating unit 123 is greater than 2. It should be noted that the length of the heating unit 123 is the size of the heating unit 123 in the width direction of the atomization surface 11a, the width of the heating unit 123 is the size of the heating unit 123 in the length direction of the atomization surface 11a, and the aspect ratio of each heating unit 123 is greater than 2, so that the distance between the central high temperature zone of the heating unit 123 and the connection between the first electrode 121 and the second electrode 122 can be increased, and to a certain extent, the failure of the connection between the heating unit 123 and the first electrode 121 and the second electrode 122 can be avoided, and the situation of anode corrosion caused by wet burning of the atomization core 10 can be improved.

In some embodiments, at least two heating units 123 are arranged in parallel and spaced apart.
