Description

The electronic heating atomization device is a device that changes liquid into gas by electrically heating the atomized liquid. It mainly uses electric energy to heat the atomized liquid to boiling point, and then forms atomized steam and air to form an aerosol substance. It is currently mainly used in the field of electronic cigarettes, and there is also a trend of expanding to the fields of beauty and medical treatment. The electronic heating atomization device usually includes a liquid guide, a heating element, and a liquid storage tank for storing liquid. During the use of the device, the liquid guide conducts the liquid in the liquid storage tank to the heating element. The heating element is powered on and heats up to atomize the liquid. The liquid in the oil storage tank is consumed and extra space is created. At this time, the air pressure in the extra space becomes smaller, and the external atmospheric pressure is higher than the air pressure in the oil storage tank. Therefore, there will be outside air that will enter the liquid storage tank through the gap between the liquid storage tank and the outside on the device. At this time, when the air enters, it often occupies part of the liquid guide channel of the liquid guide, causing the liquid to be unsmooth and affecting the liquid supply of the guide liquid.

However, it should be clear to those skilled in the art that the present invention may 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 prevent unnecessary details from obstructing the description of the present invention.

Referring to Figs. 1-11, an electronic heating atomization assembly 1 in one embodiment of the present invention comprises a substrate 11, a liquid guide 12 for conducting liquid, and a heating element 13 for heating and atomizing the liquid in the liquid guide 12, wherein the heating element 13 is in contact with the liquid guide 12, a receiving cavity 116 is provided on the substrate 11, the liquid guide 12 and the heating element 13 are arranged in the receiving cavity 116, a liquid inlet recess 111 is provided on the outer side of the substrate 11, the liquid inlet recess 111 forms a liquid inlet opening 1111 open to the outside, and the substrate 11 is provided with at least two connecting portions of the liquid inlet recess 111 and the receiving cavity 116 at a position in the liquid inlet recess 111. There are liquid inlet capillaries 112 to allow liquid outside the substrate 11 to enter the accommodating chamber 116 from the liquid inlet recess 111 and the liquid inlet capillaries 112, and contact with the liquid guiding member 12. The liquid guiding member 12 is usually made of a porous material with numerous micropores. The liquid guiding member 12 absorbs and conducts the liquid to the heating member 13. The heating member 13 is powered on and generates heat to heat the liquid into atomized liquid. The liquid inlet opening 1111 is used to control the liquid inlet area to avoid leakage of the atomized liquid due to an excessively large liquid inlet area. A ventilation channel 115 connecting the outside and the accommodating chamber 116 is provided on the substrate 11, and the ventilation channel 115 is arranged at a position outside the liquid inlet recess 111.

Referring to Figures 14 and 16, when the electronic heating atomization component 1 is used in an electronic heating atomization device, a liquid storage tank 21 for storing liquid 3 is usually provided on the electronic heating atomization device. The liquid storage tank 21 is connected to the liquid inlet opening 1111 of the electronic heating atomization component 1. The liquid 3 enters the accommodating cavity 116 through the liquid inlet opening 1111, the liquid inlet recess 111 and the liquid inlet hole, and contacts the liquid guiding member 12. The liquid guiding member 12 absorbs and conducts the liquid 3 to the heating member 13. The heating member 13 is powered on to heat the atomized liquid 3, consuming the liquid 3 in the liquid storage tank 21, and the external air enters the liquid storage tank 21 through the ventilation channel 115, so that the liquid storage tank 21 maintains air pressure balance with the outside.

15 and 17 , the electronic heating atomization component 1 is designed with a liquid inlet capillary pore 112 at the liquid inlet recess 111. The tension of the liquid 3 in the liquid inlet capillary pore 112 and the smaller micropore characteristics of the liquid guide 12 itself increase the resistance of external air entering the liquid storage tank 21 from the liquid inlet recess 111. At the same time, a ventilation channel 115 is provided at a position other than the liquid inlet recess 111. In this way, since the resistance of external air entering the liquid storage tank 21 from the liquid inlet recess 111 is large, and the resistance of entering the liquid storage tank 21 from the ventilation channel 115 is small, the air tends to enter the liquid storage tank 21 from the ventilation channel 115, thereby effectively controlling the gas entry path and preventing part of the gas from entering from the liquid inlet recess 111 and occupying the liquid supply channel, affecting the liquid supply or even causing the heating element 13 to burn.

The liquid inlet recess 111 is arranged on the side wall 110 of the base 11, and a liquid inlet opening 1111 is formed on one side of the liquid inlet recess 111 in the extension direction of the side wall 110, and at the same time, a second opening 1112 is also opened on one side of the liquid inlet recess 111 in the thickness direction of the side wall 110, but the second opening 1112 is not used for liquid inlet; the liquid inlet capillary pores 112 penetrate the side wall 110 along the thickness direction of the side wall 110 to connect the liquid inlet recess 111 with the accommodating chamber 116. With such a design, when the electronic heating atomization component 1 is applied to an electronic heating atomization device, the housing 2 of the device covers the second opening 1112, leaving the liquid inlet opening 1111 to communicate with the liquid storage tank 21, and the liquid 3 in the liquid storage tank 21 enters the liquid inlet recess 111 through the liquid inlet opening 1111. In the embodiment of FIG. 4 , the liquid inlet recess 111 forms a liquid inlet opening 1111 on one longitudinal side and a second opening 1112 on one lateral side. The liquid inlet capillary hole 112 transversely penetrates the side wall 110 of the base 11 .

3-4, the depression depth U of the liquid inlet recess 111 along the wall thickness direction of the side wall 110 is smaller than the width V, and/or the depression depth U of the liquid inlet recess 111 along the wall thickness direction of the side wall 110 is smaller than the dimension W along the direction of the liquid inlet opening 1111. With such a design, when the electronic heating atomization assembly 1 is applied to an electronic heating atomization device, the shell 2 of the device covers the second opening 1112, leaving the liquid inlet opening 1111 to communicate with the liquid storage tank 21, and the inner side surface of the shell 2 or the inner side surface of the sealing member 14 and the liquid inlet recess 111 define a liquid inlet capillary narrow groove 23 (see FIG. 15). The narrow capillary groove 23 for liquid inlet is a narrow and long area with a certain length, and its function is as follows: referring to Figures 15 and 17, ① the capillary force formed by the tension of the liquid 3 in the narrow capillary groove 23 for liquid inlet makes it more difficult for air to enter the position of the capillary hole 112 for liquid inlet, that is, when the air pressure in the liquid storage tank 21 of the electronic heating atomization device decreases, the liquid 3 at the position of the capillary hole 112 needs to be squeezed away when the outside air wants to enter the liquid storage tank 21, and the narrow capillary groove 23 for liquid inlet formed at the position of the capillary hole 112 has a greater resistance, and the air pressure inside and outside the liquid storage tank 21 needs to reach a greater difference before it can be squeezed away. 1. The liquid 3 at the liquid inlet capillary pore 112, on the contrary, the liquid film at the opening position of the ventilation channel 115 (see Figure 16) is better broken, so the path of the gas during ventilation can be more effectively controlled, and the air is mainly ventilated from the ventilation channel 115, avoiding the problem of gas entering the liquid storage tank 21 from the liquid inlet capillary narrow groove 23 instead of the predetermined ventilation channel 115, thereby occupying the liquid guide channel and causing the core to be stuck due to the unsmooth liquid supply during operation; 2. The liquid inlet capillary narrow groove 23 can quickly discharge the gas in the liquid 3 due to the tension of the liquid 3, avoiding the formation of air bubbles that affect the liquid guide; 3. When the electronic heating atomization component 1 is inverted (usually the normal use state of the electronic heating atomization component 1 is the state where the liquid inlet capillary hole 112 is upward, and the liquid storage tank 21 of the device is arranged above the electronic heating atomization component 1), the capillary narrow groove 23 can also ensure that there is a small amount of liquid 3 in the liquid inlet capillary narrow groove 23 for heating and atomization. When the user is lying down to use it, the liquid 3 in the liquid inlet capillary narrow groove 23 can also supply a certain amount of atomization steam. When it is placed upright again (the electronic heating atomization component 1 is in the state where the liquid inlet capillary hole 112 is upward), the liquid inlet capillary narrow groove 23 will be quickly filled with liquid 3.

Referring to FIG. 4 , the depression depth U of the liquid inlet recess 111 along the wall thickness direction of the side wall 110 is less than or equal to 1 mm. This dimension enables the narrow dimension of the liquid inlet capillary groove 23 formed when the electronic heating atomization assembly 1 is applied to an electronic cigarette (i.e., the dimension along the wall thickness direction of the side wall 110 of the substrate 11) to be less than or equal to 1 mm, which can allow the liquid 3 to form a suitable tension and better achieve the technical effect of preventing part of the gas from entering from the liquid inlet recess 111 and occupying the liquid supply channel.

Referring to Figures 5-11, the base 11 is provided with a raised dividing rib 113 in the liquid inlet recess 111, and the dividing rib 113 extends from the direction close to the liquid inlet opening 1111 to the direction away from the liquid inlet opening 1111, separating the at least two liquid inlet capillary holes 112, and separating the liquid inlet recess 111 into at least two liquid inlet channels 1131 leading to the liquid inlet capillary holes 112. A large liquid inlet recess 111 is divided into multiple small liquid inlet channels 1131 by the dividing ribs, which is used to increase the capillary tension at the liquid inlet channel 1131, so that the capillary tension of the liquid 3 is greater and it is not easily broken by the gas.

1-3, the electronic heating atomization assembly 1 includes a seal 14, which is arranged on the outside of the base 11, and the partition rib 113 supports the inner surface of the seal 14. Because the seal 14 is usually made of elastic deformable material, it can prevent the liquid inlet capillary pore 112 from being deformed and blocked by the seal 14 and losing the liquid inlet area.

8-11 , a connecting notch 1132 for connecting adjacent liquid inlet channels 1131 is provided at one end of the dividing rib 113 away from the liquid inlet opening 1111, so as to allow connection between the separated small liquid inlet channels 1131, thereby allowing the liquid 3 to flow between the small liquid inlet channels 1131 and ensure smooth liquid supply.

Referring to Figure 5, the liquid inlet capillary 112 includes a first partial hole 1121 and a second partial hole 1122 which are interconnected. The first partial hole 1121 extends from close to the liquid inlet opening 1111 to away from the liquid inlet opening 1111, so that the liquid inlet capillary 112 is in an "inverted T" shape. Since one end of the first partial hole 1121 is close to the liquid inlet opening 1111, the liquid 3 at the liquid inlet opening 1111 can be better guided and dispersed to various parts of the liquid inlet capillary 112, which can ensure that the liquid 3 is in balanced contact with the liquid guiding member 12 in the accommodating chamber 116.

Referring to 6-7, the base 11 is provided with a liquid guide groove 114 extending from near the liquid inlet opening 1111 to far away from the liquid inlet opening 1111 in the liquid inlet recess 111, and the liquid guide groove 114 is connected to the liquid inlet capillary hole 112 to ensure smooth liquid supply to the liquid inlet capillary hole 112. Such a design can be used in a narrower structure of an electronic heating atomization component 1, and when the space is limited and the narrow liquid inlet capillary groove 23 defined by the liquid inlet recess 111 and the housing 2 or the sealing member 14 of the device is small, such a design can be used to achieve smooth liquid supply.

Referring to Figures 12-17, an electronic heating atomization device in one embodiment of the present invention includes a shell 2 and the above-mentioned electronic heating atomization component 1 arranged in the shell 2, the inner surface of the shell 2 and the liquid inlet recess 111 define a liquid inlet capillary narrow groove 23, the liquid inlet opening 1111 is the opening of the liquid inlet capillary narrow groove 23, a liquid storage tank 21 is provided on the shell 2, and the liquid storage tank 21 is connected to the liquid inlet opening 1111; the electronic heating atomization component 1 includes a sealing member 14 for preventing the liquid 3 in the liquid storage tank 21 from leaking out, and the sealing member 14 is arranged between the base 11 and the shell 2; an air duct 22 is provided on the shell 2, and the air duct 22 is connected to the electronic heating atomization component 1, so that the atomized steam generated by the electronic heating atomization component 1 can flow out of the device from the air duct 22.

The base body 11 is provided with a raised dividing rib 113 in the liquid inlet recess 111, and the dividing rib 113 extends from close to the liquid inlet opening 1111 to away from the liquid inlet opening 1111, separating the at least two liquid inlet capillary holes 112, and dividing the liquid inlet recess 111 into at least two liquid inlet channels 1131 leading to the liquid inlet capillary holes 112; the dividing rib 113 supports the inner surface of the shell 2 or the sealing member 14, which can prevent the shell 2 or the sealing member 14 from deforming and blocking the liquid inlet capillary holes 112, resulting in the problem of loss of liquid inlet area.

Referring to Figure 17, the electronic heating atomization component device is designed with a liquid inlet capillary pore 112 at the liquid inlet recess 111. The tension of the liquid 3 in the liquid inlet capillary pore 112 and the smaller micropore characteristics of the liquid guide 12 itself increase the resistance of external air entering the liquid storage tank 21 from the liquid inlet recess 111. At the same time, a ventilation channel 115 is provided at a position outside the liquid inlet recess 111. In this way, since the resistance of external air entering the liquid storage tank 21 from the liquid inlet recess 111 is large, and the resistance of entering the liquid storage tank 21 from the ventilation channel 115 is small, the air tends to enter the liquid storage tank 21 from the ventilation channel 115, thereby effectively controlling the gas entry path and preventing part of the gas from entering from the liquid inlet recess 111 and occupying the liquid supply channel, affecting the liquid supply or even burning the heating element 13.

Referring to Figures 14 and 16, the liquid storage tank 21 in the electronic heating atomization device is connected to the liquid inlet opening 1111 of the electronic heating atomization component 1. The liquid 3 enters the accommodating chamber 116 through the liquid inlet opening 1111, the liquid inlet recess 111 and the liquid inlet hole, and contacts the liquid guiding member 12. The liquid guiding member 12 absorbs and conducts the liquid 3 to the heating member 13. The heating member 13 is powered on to heat the atomized liquid 3, consumes the liquid 3 in the liquid storage tank 21, and the external air enters the liquid storage tank 21 through the ventilation channel 115, so that the liquid storage tank 21 maintains air pressure balance with the outside.

15 and 17 , the electronic heating atomization component 1 is designed with a liquid inlet capillary pore 112 at the liquid inlet recess 111. The tension of the liquid 3 in the liquid inlet capillary pore 112 and the smaller micropore characteristics of the liquid guide 12 itself increase the resistance of external air entering the liquid storage tank 21 from the liquid inlet recess 111. At the same time, a ventilation channel 115 is provided at a position other than the liquid inlet recess 111. In this way, since the resistance of external air entering the liquid storage tank 21 from the liquid inlet recess 111 is large, and the resistance of entering the liquid storage tank 21 from the ventilation channel 115 is small, the air tends to enter the liquid storage tank 21 from the ventilation channel 115, thereby effectively controlling the gas entry path and preventing part of the gas from entering from the liquid inlet recess 111 and occupying the liquid supply channel, affecting the liquid supply or even causing the heating element 13 to burn.

The liquid inlet recess 111 is arranged on the side wall 110 of the base 11, and a liquid inlet opening 1111 is formed on one side of the liquid inlet recess 111 in the extension direction of the side wall 110, and at the same time, a second opening 1112 is also opened on one side of the liquid inlet recess 111 in the thickness direction of the side wall 110, but the second opening 1112 is not used for liquid inlet; the liquid inlet capillary pores 112 penetrate the side wall 110 along the thickness direction of the side wall 110 to connect the liquid inlet recess 111 with the accommodating chamber 116. With such a design, when the electronic heating atomization component 1 is applied to an electronic heating atomization device, the housing 2 of the device covers the second opening 1112, leaving the liquid inlet opening 1111 to communicate with the liquid storage tank 21, and the liquid 3 in the liquid storage tank 21 enters the liquid inlet recess 111 through the liquid inlet opening 1111. In the embodiment of FIG. 4 , the liquid inlet recess 111 forms a liquid inlet opening 1111 on one longitudinal side and a second opening 1112 on one lateral side. The liquid inlet capillary hole 112 transversely penetrates the side wall 110 of the base 11 .

3-4, the depression depth U of the liquid inlet recess 111 along the wall thickness direction of the side wall 110 is smaller than the width V, and/or the depression depth U of the liquid inlet recess 111 along the wall thickness direction of the side wall 110 is smaller than the dimension W along the direction of the liquid inlet opening 1111. With such a design, when the electronic heating atomization assembly 1 is applied to an electronic heating atomization device, the shell 2 of the device covers the second opening 1112, leaving the liquid inlet opening 1111 to communicate with the liquid storage tank 21, and the inner side surface of the shell 2 or the inner side surface of the sealing member 14 and the liquid inlet recess 111 define a liquid inlet capillary narrow groove 23 (see FIG. 15). The narrow capillary groove 23 for liquid inlet is a narrow and long area with a certain length, and its function is as follows: referring to Figures 15 and 17, ① the capillary force formed by the tension of the liquid 3 in the narrow capillary groove 23 for liquid inlet makes it more difficult for air to enter the position of the capillary hole 112 for liquid inlet, that is, when the air pressure in the liquid storage tank 21 of the electronic heating atomization device decreases, the liquid 3 at the position of the capillary hole 112 needs to be squeezed away when the outside air wants to enter the liquid storage tank 21, and the narrow capillary groove 23 for liquid inlet formed at the position of the capillary hole 112 has a greater resistance, and the air pressure inside and outside the liquid storage tank 21 needs to reach a greater difference before it can be squeezed away. 1. The liquid 3 at the liquid inlet capillary pore 112, on the contrary, the liquid film at the opening position of the ventilation channel 115 (see Figure 16) is better broken, so the path of the gas during ventilation can be more effectively controlled, and the air is mainly ventilated from the ventilation channel 115, avoiding the problem of gas entering the liquid storage tank 21 from the liquid inlet capillary narrow groove 23 instead of the predetermined ventilation channel 115, thereby occupying the liquid guide channel and causing the core to be stuck due to the unsmooth liquid supply during operation; 2. The liquid inlet capillary narrow groove 23 can quickly discharge the gas in the liquid 3 due to the tension of the liquid 3, avoiding the formation of air bubbles that affect the liquid guide; 3. When the electronic heating atomization component 1 is inverted (usually the normal use state of the electronic heating atomization component 1 is the state where the liquid inlet capillary hole 112 is upward, and the liquid storage tank 21 of the device is arranged above the electronic heating atomization component 1), the capillary narrow groove 23 can also ensure that there is a small amount of liquid 3 in the liquid inlet capillary narrow groove 23 for heating and atomization. When the user is lying down to use it, the liquid 3 in the liquid inlet capillary narrow groove 23 can also supply a certain amount of atomization steam. When it is placed upright again (the electronic heating atomization component 1 is in the state where the liquid inlet capillary hole 112 is upward), the liquid inlet capillary narrow groove 23 will be quickly filled with liquid 3.
