Description

Technical Field

[0001] The utility model relates to the technical field of atomization, in particular to an electronic atomization device, an atomizer and an atomization core thereof. Background Art

[0002] The principle of an electronic atomization device is that liquid is heated to the boiling point through heating to form atomized steam, and the atomized steam is mixed with air to form aerosol substances, which can currently be applied in the fields of electronic cigarettes, home, beauty, medical treatment, etc.

[0003] The core of the atomization device lies in the heating element and the liquid guiding element. After the heating element and the liquid guiding element are in full contact, the heat generated by the heating body heats the liquid on the liquid guiding element to the boiling point and atomizes it into atomized steam. The contact between the heating element and the liquid guiding element is related to the stability and consistency of the atomization effect. Poor contact between the heating element and the liquid guiding element will cause the temperature of the heating body to rise, that is, the wick burns, affecting the consumption experience. At the same time, high temperature will generate harmful substances such as formaldehyde, affecting health. In related technologies, the heating elements are generally flat-structured heating sheets, heating films, heating wires, heating meshes, etc. In order to facilitate carrying, their volumes are relatively small, and in order to quickly reach the set temperature, they are relatively thin and have poor supporting force, causing great inconvenience for assembly; moreover, in addition to low supporting strength, the flat structure also has a relatively small atomization area and a low atomization amount.

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0040] In the following description, for the purpose of illustration rather than limitation, specific details such as specific system structures, technologies, etc. are presented in order to thoroughly understand the embodiments of the present utility model. However, those skilled in the art should clearly understand that the present utility model can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid unnecessary details from interfering with the description of the present utility model.

[0041] The present utility model constructs an electronic atomization device 100, which includes a component for heating and atomizing an aerosol generating matrix. In this embodiment, the aerosol generating matrix can be a liquid aerosol generating matrix, that is, an atomizing liquid. The electronic atomization device 100 may include an atomizer and a power supply component (not shown) detachably connected to the atomizer in some embodiments, and the power supply component is electrically connected to the atomizer. The power supply component may include a battery for supplying power to the atomizer. As Figure 1 shown, an atomizer according to an embodiment of the present utility model can be used to accommodate and heat an aerosol generating matrix.

[0042] As Figure 1 shown, in some embodiments, the atomizer includes an atomization core 10 and a housing 20. The atomization core 10 is accommodated in the housing 20. The housing 20 is provided with a liquid inlet, and a liquid storage cavity is formed in the housing 20 for storing an aerosol generating matrix such as an atomizing liquid. The liquid enters the liquid guiding member 1 through the liquid inlet. One side of the liquid storage cavity is open, and the liquid storage cavity is communicated with the heating atomization core 10 to facilitate liquid supply to the atomization core 10. A mouthpiece is formed or installed on the housing 20, and the aerosol can be discharged through the mouthpiece. Optionally, the housing 20 and the liquid inlet are of an integral structure.

[0043] Figures 2 to 4 The first embodiment of the atomizing core 10 of the present utility model is shown. The atomizing core 10 includes a liquid guiding member 1, a heating member 2, and a support body 3. The heating member 2 includes a heating portion 21 and a support portion 22 connected to the heating portion 21. The heating portion 21 is arc-shaped and is located between the liquid guiding member 1 and the support body 3. The support portion 22 is embedded in the support body 3. The function of the support body 3 is to provide support strength for the heating member 2 to support the heating member 2. The support body 3 can be made of an insulating material.

[0044] The arched portion of the heating member 2 forms the heating portion 21, and the heating portion 21 is arc-shaped, so that the heating member 2 has better support force. The main heating area of the heating member 2 is provided on the heating portion 21, so that the heating portion 21 forms an arc-shaped heating area. The surface of the arc-shaped heating area in contact with the liquid guiding member 1 is the atomizing surface 101 of the atomizing core 10. The arc-shaped structure of the heating portion 21 is beneficial to the full contact between the heating member 2 and the liquid guiding member 1 and has better support strength; compared with a flat heating member 2, it has a larger surface area. Therefore, the arc-shaped heating portion 21 has a larger atomizing area, which can increase the heating area and the atomizing amount. An atomizing channel 4 is formed in the atomizing core 10, and the atomizing channel 4 is formed by enclosing the heating member 2 and the support body 3. When the heating portion 21 heats the atomizing liquid on the liquid guiding member 1, the generated aerosol flows out through the atomizing channel 4.

[0045] The support body 3 can be in a plate shape. A through groove 31 is provided on the side surface of the support body 3 adjacent to the heating portion 21, and the number of the through grooves 31 is one. The atomizing channel 4 is formed by enclosing the end surface of the through groove 31 and the heating member 2. In this embodiment, the heating portion 21 is arranged between the liquid guiding member 1 and the support body 3, which can support the heating member 2 so that the heating member 2 is not easily deformed; at the same time, the heating member 2 can support the liquid guiding member 1 to prevent the liquid guiding member 1 from collapsing into the through groove 31 after deformation, affecting the air flow and service life.

[0046] As Figure 3 shown, in an embodiment, the support body 3 is a rectangular body, and the support portion 22 includes a first embedding portion 221 arranged flatly. The first embedding portion 221 is formed by extending parallel to each other from both ends of the heating portion 21, and the first embedding portion 221 is embedded in the support body 3. Optionally, the extending direction of the first embedding portion 221 is parallel to the thickness direction of the support body 3.

[0047] Figure 5 and Figure 6Shows a second embodiment of the atomization core 10 of the present utility model. In this embodiment, the support portion 22 includes a bent second embedding portion 222, and the second embedding portion 222 extends from both ends of the heating portion 21 in a direction away from the center of the arc of the heating portion 21, and the second embedding portion 222 is embedded in the support body 3. Optionally, the extending direction of the second embedding portion 222 is parallel to the length direction of the support body 3.

[0048] In some embodiments, the shape of the support body 3 is different from that of the above embodiments. Multiple grooves may be provided on the support body 3, so that multiple atomization channels 4 can be formed between the heating element 2 and the support body 3.

[0049] Figure 7 and Figure 8 Shows a third embodiment of the atomization core 10 of the present utility model. In this embodiment, the heating element 2 is tubular and can be curled into a tubular shape from a planar shape. The support body 3 is columnar, and the support body 3 is an integral structure. The support body 3 is provided with a first through groove 311 and a second through groove 312. The first through groove 311 and the second through groove 312 are respectively arranged on opposite sides of the support body 3. The atomization channel 4 includes a first atomization channel 41 and a second atomization channel 42. The first atomization channel 41 is formed by enclosing the end face of the first through groove 311 and the heating element 2, and the second atomization channel 42 is formed by enclosing the end face of the second through groove 312 and the heating element 2. The first atomization channel 41 and the second atomization channel 42 are axially isolated from each other.

[0050] The shape of the heating element 2 is approximately the same as that of the support body 3. The heating element 2 is circular tubular, and the heating portion 21 and the support portion 22 are connected to form an arc. Understandably, the cross-section of the heating element 2 is not necessarily a complete circle, and the cross-section of the heating element 2 can be an arc.

[0051] The outer diameter of the heating element 2 is less than or equal to the inner diameter of the support body 3. Preferably, the outer diameter of the heating element 2 is slightly less than the inner diameter of the support body 3, so that at least part of the support portion 22 of the heating element 2 is embedded in the surface of the support body 3, and the heating element 2 can be better supported. The function of the support body 3 is to support the heating element 2. Therefore, the support body 3 needs to leave a position for the installation of the heating element 2 so that the heating element 2 can be exposed on the wall surface of the atomization channel 4. At the same time, the support body 3 itself needs better support strength.

[0052] Figure 9 Shows a fourth embodiment of the atomization core 10 of the present utility model. In this embodiment, the heating element 2 is elliptical tubular, and the heating element 2 includes an arc-shaped heating portion 21 and a straight support portion 22 connected to the heating portion 21. The support portion 22 is embedded inside the support body 3, and the heating portion 21 is correspondingly arranged with the atomization channel 4 and exposed on the surface of the support body 3.

[0053] Figure 10The fifth embodiment of the atomization core 10 of the present utility model is shown. In this embodiment, an installation space for installing the heating element 2 is formed inside the support body 3. Different from the above-mentioned integral support body 3, the support body 3 of this embodiment includes a support base 32, at least two support arms 33, and a support rib 34. At least two support arms 33 are arranged at intervals on the support base 32, and the support rib 34 is connected between at least two support arms 33. The installation space is formed by enclosing the inner wall surfaces of the support rib 34 and the inner wall surfaces of the two support arms 33.

[0054] Optionally, the support base 32 is annular and includes a first installation opening 321. The number of support arms 33 is two. Each support arm 33 includes a first end and a second end opposite to the first end. The first end of the support arm 33 is fixed on the first installation opening 321 of the support base 32, and the second end of the support arm 33 extends towards the end away from the support base 32. The support rib 34 is arranged at the second end of the support arm 33 and is connected between the two support arms 33.

In this embodiment, an installation space for installing the heating element 2 is formed inside the support body 3. The support body 3 includes a support base 32, at least two support arms 33, and a support top seat 35. At least two support arms 33 are arranged at intervals on the support base 32, and the support top seat 35 is arranged on the top of at least two support arms 33. The installation space is formed by enclosing the inner wall surfaces of the two support arms 33; the atomization channel 4 is formed by enclosing at least two support arms 33 and the heating element 2.

[0056] Optionally, the support base 32 is annular and includes a first installation opening 321. The number of support arms 33 is two. Each support arm 33 includes a first end and a second end opposite to the first end. The first end of the support arm 33 is fixed on the first installation opening 321 of the support base 32, and the second end of the support arm 33 extends towards the end away from the support base 32. The support top seat 35 is annular, and the support top seat 35 can have the same shape as the support base 32 and also includes a second installation opening 351. The second end of the support arm 33 is fixed on the second installation opening 351 of the support top seat 35.

[0057] The heating element 2 can include multiple heating zones, and the multiple heating zones can work alternately or simultaneously. For example Figure 13As shown, in this embodiment, the heating element 2 includes two heating zones. Optionally, the heating element 2 with this structure can be adopted in the third to sixth embodiments. The heating element 2 includes a first electrode 23, a second electrode 24, and a third electrode 25. The second electrode 24 serves as a common electrode and is located between the first electrode 23 and the third electrode 25. The electrode polarities of the second electrode 24 and the first electrode 23 as well as the third electrode 25 are different; the heating part 21 connected between the first electrode 23 and the second electrode 24 forms a first heating zone 211, and the heating part 21 connected between the third electrode 25 and the second electrode 24 forms a second heating zone 212. Optionally, the second electrode 24 is in a T shape, and the first electrode 23 and the third electrode 25 are in a "7" shape. When the first electrode 23 and the second electrode 24 are energized, the first heating zone 211 operates; when the second electrode 24 and the third electrode 25 are energized, the second heating zone 212 operates. Through circuit control, the first heating zone 211 and the second heating zone 212 can operate alternately or simultaneously, and can be selectively switched to different working modes to meet the requirements of different atomization amounts. It can be understood that, for example, the first electrode 23 and the third electrode 25 can be positive electrodes, and the second electrode 24 can be a negative electrode; or the first electrode 23 and the third electrode 25 can be negative electrodes, and the second electrode 24 can be a positive electrode. The polarities of these three electrodes can be adjusted according to the actual situation and are not limited herein.

The heating part 21 is arc-shaped, so that the heating element 2 has better supporting force, which is beneficial to the full contact between the heating element 2 and the liquid guiding member 1. Compared with the flat heating element 2, the arc-shaped heating part 21 has a larger surface area and a larger atomization area, which can increase the heating area and the atomization amount.
