As shown inFIGS.1to2andFIG.5, a porous liquid conducting member1with a smooth liquid conduction in an embodiment of the present disclosure is made of a porous material, preferably a ceramic material. The liquid conducting member1is provided with a hollow cavity10therein, and includes an inner side11and an outer side12. The inner side11or the outer side12is configured to be in contact with a liquid3, and is provided with an air exchange recess13to form a thin-wall14on the liquid conducting member1. A wall thickness of the thin-wall14is smaller than a wall thickness between the inner side11and the outer side12, so that air can be conducted from the inside to the outside of the liquid conducting member1or from the outside to the inside of the liquid conducting member1through the thin-wall14. The air exchange recess13is in a hole or groove shape.

Generally, when the liquid conducting member1is applied to an atomizing device, a heating member2is provided on the liquid conducting member1, a heating area21of the heating member2is located at a position staggered from the thin-wall14, and the inner side11or the outer side12of the liquid conducting member1is configured to be in contact with the liquid3in a liquid storage chamber of the atomizing device, and the liquid conducting member1conducts the liquid3to the heating member2for heating and atomizing. During the atomization process of the atomizing assembly, the liquid3in the liquid storage chamber will be consumed. Due to that the liquid storage chamber is in a sealed state, with the consumption of the liquid3, a space in the liquid storage chamber becomes larger and an internal air pressure in the liquid storage chamber becomes smaller than an external atmospheric pressure. Besides, the air can only enter the liquid storage chamber via porous channels in the porous liquid conducting member1. By providing the air exchange recess13, the air will enter the liquid storage chamber through the thin-wall14of the air exchange recess13, so as to avoid the porous channels in the liquid conducting member1at the heating area21from being occupied by the air when the air enters the liquid storage chamber, so that all micropores in the liquid conducting member1corresponding to the heating area21are used to transmit the liquid3, and the porous channels for the liquid supply and for the air exchange in the porous liquid conducting member1are separated, so as to achieve a more smooth liquid conduction in the heating area21. The principle is that at the thin-wall14formed by the air exchange recess13of the porous liquid conducting member1, the thickness of the thin-wall14is small, and the length of each porous channel is small, thus the external air can enter the liquid storage chamber via the porous channels in the thin-wall14when the pressure difference between the liquid storage chamber and the external air is relatively small.

Referring toFIGS.1-14, in these embodiments, the liquid conducting member1is in a rectangle shape, and the hollow cavity10is a liquid storage groove disposed in an upper side of the liquid conducting member1.

Referring toFIGS.1-2andFIG.5, in this embodiment, the air exchange recess13is located at a bottom of the liquid storage groove, a bottom of the liquid storage groove is provided with liquid supply holes15, each liquid supply hole15is a blind hole, and the wall thickness a of the thin-wall14formed by the air exchange recess13is smaller than the wall thickness b between the bottom of the liquid supply hole15and the lower side of the liquid conducting member1. The depth of the air exchange hole is larger than the depth of the short-distance liquid supply hole15. Each thin-wall14is a wall between the bottom of the corresponding air exchange recess13and a lower surface of the liquid conducting member1, and each air exchange recess13is a blind hole, so that the air can pass through the thin-wall14to the air exchange recess13from the outside and then enter the liquid storage groove.

The large liquid storage groove is able to store more liquid3to supply to the liquid conducting member for absorption after consumption. More than one short-distance liquid supply hole15is provided in the large liquid storage groove, so that the liquid3can reach the heating member on the outer side of the liquid conducting member more conveniently with a shorter distance.

The principle is: when the liquid conducting member1is applied in the atomizing device, the liquid conducting member1is provided with the heating member2, and the position of the air exchange recess is outside the heating area of the heating member. The deeper air exchange recess13forms the thin-wall14, so that a wall thickness difference is formed between the wall thickness of the liquid conducting member1corresponding to the heating area21and that corresponding to the non-heating area21of the heating member2. In this way, the position with a thinner wall thickness has a shorter micropore path than that with a thicker wall thickness, and thus has a smaller pressure required for the air. When the pressure in the liquid storage chamber is smaller than the atmospheric pressure, the air can enter the liquid storage chamber through the thin-wall14of the air exchange recess13, so that the air will not occupy the micropores in the liquid conducting member1corresponding to the heating area21, and thus the liquid conducting member1corresponding to the heating area21can supply liquid more smoothly.

Referring toFIGS.6-8, in this embodiment, the thin-wall14is a wall between a side wall of the air exchange recess13and the outer side12of the liquid conducting member1. Herein, a size of one end of the liquid conducting member1provided with the liquid storage groove is larger than that of the opposite end of the liquid conducting member1, so that the liquid conducting member1is in a stepped shape. In the embodiment ofFIGS.6-8, the liquid storage groove is defined in the upper side of the liquid conducting member1, and the size of the upper end of the liquid conducting member1is larger than that of the lower end of the liquid conducting member1. In this way, the thin-wall14can be formed between the air exchange recess13and the side wall, to ensure the separation of the air flow and the liquid flow, so as to avoid affecting the transmission of the liquid3to the heating member2caused by the air occupying the capillary micropores for the liquid3.

Referring toFIGS.9-10, in this embodiment, the air exchange recess13is defined in a side wall of the liquid storage groove, and the air exchange recess13is in a hole or groove shape, so that the thin-wall14of the liquid conducting member1has fewer porous channels, so that the external airflow can better enter the liquid conducting member1.

Referring toFIGS.11-14, in these embodiments, the air exchange recess13is defined in an outer side of the liquid conducting member1, and the air exchange recess13is a hole or a groove, so that the thin-wall14on the liquid conducting member is communicated with the upper side of the liquid conducting member1(seeFIGS.11-12), or is isolated from the upper side of the liquid conducting member1(seeFIGS.13-14). Thereby, the external air can enter from the thin-wall14instead of from the bottom of the heating member2, so as to avoid the air occupying the liquid inlet channel, and to ensure sufficient liquid supply.

Referring toFIGS.15-20, in these embodiments, the hollow cavity10extends through the liquid conducting member1from the upper side to the lower side thereof, thus the liquid conducting member1is tubular or annular, and the air exchange recess13is defined in the outer wall of the liquid conducting member1(seeFIGS.15-17) or the inner wall of the liquid conducting member1(seeFIGS.18-20). When a pressure difference is formed between the inside and the outside of the liquid conducting member1, the air enters the hollow cavity10in the liquid conducting member1for storing liquid through the thin-wall14, so as to avoid the occupation of the porous channels for the liquid3when the air enters the hollow cavity10, and ensure a sufficient supply of the liquid3.

For the above embodiments, a thickness of each thin-wall14formed by each corresponding air exchange recess13is 0.1 mm to 0.5 mm, and an area of each thin-wall14formed by each corresponding air exchange recess13is 0.05-15 mm2, a porosity of the liquid conducting member1is 20% to 80%, and an average micropore diameter of the liquid conducting member1is 5 μm to 50 μm.

Referring toFIGS.3-5, a heating assembly according to an embodiment of the disclosure includes the above-mentioned porous liquid conducting member1with a smooth liquid conduction, and further includes a heating member2arranged on the liquid conducting member1. The heating area21of the heating member2is not located at the thin-wall14formed by the air exchange recess13, in other words, the heating area21of the heating member2is staggered with the thin-wall14formed by the air exchange recess13. The heating assembly can be applied in an atomizing device, the heating area21of the heating member2is located at a position staggered from the thin-wall14, the inner side11or the outer side12of the liquid conducting member1is configured to be in contact with the liquid3in the liquid storage chamber of the atomizing device, and the liquid conducting member1transmits the liquid3to the heating member2for heating and atomizing. Since the liquid3in the liquid storage chamber will be consumed during the atomizing process of the atomizing assembly, and the liquid storage chamber is in a sealed state, a space in the liquid storage chamber becomes larger and an internal air pressure in the liquid storage chamber becomes smaller than an external atmospheric pressure with the consumption of the liquid3. Besides, the air can only enter the liquid storage chamber via the porous channels in the porous liquid conducting member1. With the air exchange recess13, the air will enter the liquid storage chamber through the thin-wall14of the air exchange recess13, so as to avoid the porous channels in the liquid conducting member1at the heating area21from being occupied by the air when the air enters the liquid storage chamber, so that all the micropores in the liquid conducting member1corresponding to the heating area21are used to transfer the liquid3, so as to achieve a more smooth liquid conduction in the heating area21. The principle is that at the thin-wall14formed by the air exchange recess13of the porous liquid conducting member1, the thickness of the thin-wall14is small, and thus the length of each porous channel is small, therefore the external air can enter the liquid storage chamber via the porous channels in the thin-wall14when the pressure difference between the liquid storage chamber and the external air is relatively small.

An atomizing device according to an embodiment of the disclosure includes a housing and the above-mentioned heating assembly disposed in the housing. A liquid storage chamber is defined in the housing, and is communicated with the hollow cavity10in the liquid conducting member1, so that the liquid in the liquid storage chamber can enter the hollow cavity10, and is further conducted to the heating member2through the liquid conducting member1, and the air can enter the liquid storage chamber through the air exchange recess13. In the atomizing device, the heating area21of the heating member2is located at a position staggered from the thin-wall14, the inner side11or the outer side12of the liquid conducting member1is configured to be in contact with the liquid3in the liquid storage chamber of the atomizing device, and the liquid conducting member1transmits the liquid3to the heating member2for heating and atomizing. Since the liquid3in the liquid storage chamber will be consumed during the atomizing process of the atomizing assembly, and the liquid storage chamber is in a sealed state, a space in the liquid storage chamber becomes larger and an internal air pressure in the liquid storage chamber becomes smaller than an external atmospheric pressure with the consumption of the liquid3. Besides, the air can only enter the liquid storage chamber via the porous channels in the porous liquid conducting member1. With the air exchange recess13, the air will enter the liquid storage chamber through the thin-wall14of the air exchange recess13, so as to avoid the porous channels in the liquid conducting member1at the heating area21from being occupied by the air when the air enters the liquid storage chamber, so that all the micropores in the liquid conducting member1corresponding to the heating area21are used to transfer the liquid3, so as to achieve a more smooth liquid conduction in the heating area21. The principle is that at the thin-wall14formed by the air exchange recess13of the porous liquid conducting member1, the thickness of the thin-wall14is small, and thus the length of each porous channel is small, therefore the external air can enter the liquid storage chamber via the porous channels in the thin-wall14when the pressure difference between the liquid storage chamber and the external air is relatively small.
