Description

Technical Field

[0001] The present invention relates to the technical field of heating and atomizing by using a porous liquid-conducting body, and in particular to a porous liquid-conducting body for smooth liquid conduction, a heating component and an atomizing device. Background Art

[0002] The porous liquid guide is mainly used to conduct liquid in the atomization component and is often used in the atomization device to conduct the liquid in the atomization device to the heating element for heating and atomization. Usually one side or one surface of the liquid guide is in contact with the liquid, and the other surface is provided with a heating element in contact with the outside air. The function is to conduct the liquid in the atomization device to the heating element for heating and atomization. The porous structure in the liquid guide serves as a channel connecting the liquid in the atomizer liquid storage tank and the outside air. The liquid is mainly transmitted through the porous channels inside the liquid guide. In actual use, as the liquid is consumed, the liquid in the liquid storage tank is consumed, and the air pressure in the space inside the liquid storage tank will be lower than the outside atmospheric pressure. When the air pressure difference is too large, the outside air will be transmitted to the liquid storage tank through the porous channels in the porous liquid guide. In this way, the air will occupy a part of the porous channels in the liquid guide. If the porous channels in the heating area are occupied, the heating element in the heating area will not be able to be transmitted to the heating element in time, resulting in poor liquid conduction and local high temperature of the heating element, causing burns, which affects the user experience.

Therefore, features defined as "first," "second," "third," etc. may explicitly or implicitly include one or more of such features. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0044] In the following description, specific details such as particular system structures and techniques are provided for purposes of illustration, not limitation, to facilitate a thorough understanding of the embodiments of the present invention. However, it will be apparent to those skilled in the art that the present invention may be practiced in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0045] See also Figure 1-2 In one embodiment of the present invention, a porous liquid-conducting body 1 for smooth liquid conduction is made of a porous material, preferably a ceramic material. The liquid-conducting body 1 has a hollow cavity 10, including an inner side 11 and an outer side 12. The inner side 11 or the outer side 12 is used to contact the liquid 3. A gas exchange recess 13 is provided on the inner side 11 or the outer side 12 to form a thin wall on the liquid-conducting body 1. The wall thickness of the thin wall is less than the wall thickness between the inner side 11 and the outer side 12, so that gas can pass through the thin wall from the inside to the outside of the liquid-conducting body 1 or from the outside to the inside. The gas exchange recess 13 is in the shape of a hole or a groove.

[0046] Typically, when the liquid guide 1 is used in an atomizing device, a heating element 2 is provided on the liquid guide 1, and the heating area 21 of the heating element 2 is provided at a position avoiding the thin wall. The inner side 11 or the outer side 12 of the liquid guide 1 is used to contact the liquid 3 in the liquid storage tank of the atomizing device, and the liquid guide 1 conducts the liquid 3 to the heating element 2 for heating and atomization. Since the atomizing component consumes the liquid 3 in the liquid storage tank during the atomization process, the liquid storage tank is in a sealed state. As the liquid 3 is consumed, the space in the liquid storage tank becomes larger, and the internal air pressure is lower than the external atmospheric pressure. The gas can only reach the liquid storage tank through the porous channels in the porous liquid guide 1 through the porous channels. Since a gas exchange recess 13 is provided, the gas will pass through the thin wall of the gas exchange recess 13 to reach the liquid storage tank, avoiding the gas occupying the porous channels of the liquid guide 1 in the heating area 21 when entering the liquid storage tank, so that all the micropores of the liquid guide 1 corresponding to the heating area 21 are used to transmit the liquid 3. The porous channels for liquid supply and ventilation in the porous liquid guide 1 are separated, so as to achieve the purpose of smoother liquid conduction in the heating area 21. The principle is that the thin wall formed by the gas exchange recess 13 of the porous liquid guide 1 has a small thickness and a short porous channel. When the pressure difference between the liquid storage tank and the outside air is small, the outside air pressure can drive the air into the liquid storage tank through the porous channel of the thin wall.

[0047] See also Figure 1-14 In these embodiments, the liquid-conducting body 1 is square, and the hollow cavity 10 is a liquid storage tank provided on the upper side of the liquid-conducting body 1 .

[0048] See also Figure 1-2 and 5. In this embodiment, the gas exchange recess 13 is located at the bottom of the liquid storage tank, and a liquid supply hole 15 is provided at the bottom of the liquid storage tank, and the liquid supply hole 15 is a blind hole. The wall thickness a of the thin wall formed by the gas exchange recess 13 is less than the wall thickness b between the bottom of the liquid supply hole 15 and the lower side of the liquid guide liquid 1. The depth of the gas exchange hole is greater than the depth of the close-range liquid supply hole 15. The thin wall is the wall between the bottom of the gas exchange recess 13 and the lower surface of the liquid guide liquid 1. The gas exchange recess 13 is a blind hole to allow gas to pass through the thin wall from the outside into the gas exchange recess 13 and then into the liquid storage tank.

[0049] The large liquid storage tank can store more liquid 3 for the liquid guide to absorb after consumption. Opening one or more close-range liquid supply holes 15 on the large liquid storage tank can make it easier for the liquid 3 to reach the heating element position outside the liquid guide at a closer distance.

[0050] The principle is as follows: when the liquid guide 1 is used in an atomizing device, a heating element 2 is provided on the liquid guide 1, and the position of the gas exchange recess is outside the heating area 21 of the heating element. The deeper gas exchange recess 13 forms a thin wall, so that the wall thickness of the liquid guide 1 in the heating area 21 forms a wall thickness difference with the non-heating area 21 of the heating element 2. In this way, the micropore path at the location with thin wall thickness is shorter than that at the location with thick wall thickness, and the pressure required for the gas is smaller. When the pressure in the liquid storage tank is lower than the atmospheric pressure, the gas can enter the liquid storage tank through the thin wall position of the gas exchange recess 13. In this way, the gas will not occupy the micropores of the liquid guide 1 in the heating area 21, allowing the liquid supply of the liquid guide 1 in the heating area 21 to be smoother.

[0051] See also Figure 6-8 In this embodiment, the thin wall is the wall between the side wall of the gas exchange recess 13 and the outer side 12 of the liquid guide 1. At this time, the size of the liquid guide 1 at the end where the liquid storage tank is located is larger than the size of the opposite end, so that the liquid guide 1 forms a step-like shape; Figure 6-8 In the embodiment, the liquid reservoir is located above the liquid guide 1, with the upper end of the liquid guide 1 being larger than the lower end. Thus, by designing the gas exchange recess 13 close to the side wall to form a thin-walled portion, the gas flow and liquid flow can be separated, preventing the gas from occupying the capillary pores of the liquid 3 and affecting the conduction of the liquid 3 to the heating element 2.

[0052] See also Figure 9-10 In this embodiment, the gas exchange recess 13 is located on the side wall of the liquid storage tank. The gas exchange recess 13 is hole or groove-shaped, so that the liquid guide 1 forms a thin wall. The thin wall has fewer porous channels, allowing the external airflow to better enter the liquid guide 1.

[0053] See also Figure 11-14 In this embodiment, the gas exchange recess 13 is located on the outer surface of the liquid guide 1. The gas exchange recess 13 is a hole or groove shaped so that the liquid guide forms a thin wall and is open on the upper side of the liquid guide 1 (see Figure 11-12 ) or isolated from the upper side of the liquid conductor 1 (see Figure 13-14 ), which makes it convenient for external gas to enter through the thin wall instead of entering from the bottom heating element 2 and occupying the liquid inlet channel, thereby ensuring sufficient liquid supply.

[0054] See also Figure 15-20 In this embodiment, the hollow cavity 10 passes through the liquid guide 1 from the upper side to the lower side. The liquid guide 1 is cylindrical or annular. The gas exchange recess 13 is provided on the outer wall (see Figure 15-17 ) or medial wall (see Figure 18-20When an atmospheric pressure difference is formed inside and outside the liquid-conducting body 1, gas enters the hollow cavity 10 of the liquid-conducting body 1 through the thin wall, thereby preventing the gas from occupying the porous channels of the liquid 3 when entering the hollow cavity 10, thereby ensuring an adequate supply of the liquid 3.

[0055] For the above embodiment, the thickness of the thin wall formed by the gas exchange recess 13 is 0.1-0.5 mm, and the area of ​​the thin wall formed by each gas exchange recess 13 is 0.05-15 mm. 2 The porosity of the liquid-conducting material 1 is between 20-80%, and the average micropore diameter of the liquid-conducting material 1 is 5-50 μm.

[0056] See also Figure 3-5 A heating component according to one embodiment of the present invention includes the aforementioned porous liquid-conducting body 1 for smooth liquid conduction, and also includes a heating element 2 disposed on the liquid-conducting body 1. The heating area 21 of the heating element 2 is not located at the thin wall formed by the gas exchange recess 13, or the heating area 21 of the heating element 2 is staggered from the thin wall formed by the gas exchange recess 13. The heating component can be applied to an atomization device, wherein the heating area 21 of the heating element 2 is located at a position avoiding the thin wall, and the inner side 11 or outer side 12 of the liquid-conducting body 1 is used to contact the liquid 3 in the liquid storage tank of the atomization device. The liquid-conducting body 1 conducts the liquid 3 to the heating element 2 for heating and atomization. Since the atomizing component consumes the liquid 3 in the liquid storage tank during the atomization process, the liquid storage tank is in a sealed state. As the liquid 3 is consumed, the space in the liquid storage tank becomes larger, and the internal air pressure is lower than the external atmospheric pressure. The gas can only reach the liquid storage tank through the porous channel in the porous liquid guide 1 through the liquid guide 1. Since there is a gas exchange recess 13, the gas will pass through the thin wall of the gas exchange recess 13 to reach the liquid storage tank, avoiding the gas occupying the porous channel of the liquid guide 1 in the heating area 21 when entering the liquid storage tank, so that all the micropores of the liquid guide 1 corresponding to the heating area 21 are used to transmit liquid 3, achieving the purpose of smoother liquid conduction in the heating area 21. The principle is that the thin wall formed by the gas exchange recess 13 of the porous liquid guide 1 has a small wall thickness and a short porous channel. When the pressure difference between the liquid storage tank and the outside world is small, the outside air pressure can drive the air into the liquid storage tank through the porous channel in the thin wall.

[0057] An atomizing device according to one embodiment of the present invention includes a housing and the above-mentioned heating assembly disposed in the housing. A liquid storage tank is disposed in the housing, and the liquid storage tank is connected to the hollow cavity 10 of the liquid guide 1, so that the liquid in the liquid storage tank can enter the hollow cavity 10 and then be conducted to the heating element 2 through the liquid guide 1, and the gas can reach the liquid storage tank through the gas exchange recess 13. In the atomizing device, the heating area 21 of the heating element 2 is disposed in a position avoiding thin walls, and the inner side 11 or the outer side 12 of the liquid guide 1 is used to contact the liquid 3 in the liquid storage tank of the atomizing device. The liquid guide 1 conducts the liquid 3 to the heating element 2 for heating and atomization. Since the atomizing component consumes the liquid 3 in the liquid storage tank during the atomization process, the liquid storage tank is in a sealed state. As the liquid 3 is consumed, the space in the liquid storage tank becomes larger, and the internal air pressure is lower than the external atmospheric pressure. The gas can only reach the liquid storage tank through the porous channel in the porous liquid guide 1 through the liquid guide 1. Since there is a gas exchange recess 13, the gas will pass through the thin wall of the gas exchange recess 13 to reach the liquid storage tank, avoiding the gas occupying the porous channel of the liquid guide 1 in the heating area 21 when entering the liquid storage tank, so that all the micropores of the liquid guide 1 corresponding to the heating area 21 are used to transmit liquid 3, achieving the purpose of smoother liquid conduction in the heating area 21. The principle is that the thin wall formed by the gas exchange recess 13 of the porous liquid guide 1 has a small wall thickness and a short porous channel. When the pressure difference between the liquid storage tank and the outside world is small, the outside air pressure can drive the air into the liquid storage tank through the porous channel in the thin wall.
