Background Art

[0002] An electronic heating atomization device is a device for realizing the change from liquid to gas by electrically heating an atomizing liquid. The device mainly heats the atomizing liquid to its boiling point by electrical energy and forms an aerosol substance by mixing the formed atomized vapor with air. At present, the device is mainly used in the field of electronic cigarettes, but it is also expanding into fields such as beauty and medical treatment. Usually, an electronic heating atomization device includes a liquid guiding member, a heating member, and a liquid storage tank for storing liquid. During the use process of the device, the liquid guiding member transmits the liquid in the liquid storage tank to the heating member, and the heating member generates heat when powered on to atomize the liquid. Liquid storage tank When the liquid inside is consumed, there will be a space left. At this time, the air pressure in the empty space decreases, and the external air pressure connected Liquid storage tank becomes higher than the air pressure inside. Therefore, the external air enters the liquid storage tank through the gap connecting the liquid storage tank on the device and the outside. At this time, when the air enters, it occupies a part of the liquid guiding path in the liquid guiding member, resulting in unsmooth liquid guiding and often affecting the liquid supply of the liquid guiding body.

[0014] By implementing the technical means of the present invention, at least the following beneficial effects are obtained. Specifically, the electronic heating atomization assembly and apparatus are designed with liquid supply capillary holes in the liquid supply recess, and the tension of the liquid within the liquid supply capillary holes and the small micropores of the liquid guide member itself increase the resistance of outside air entering the storage tank from the liquid supply recess. In addition, a ventilation path is provided at locations other than the liquid supply recess. In this way, the resistance of outside air entering the storage tank from the liquid supply recess is high, and the resistance of air entering the storage tank from the ventilation path is low, so air tends to enter the storage tank from the ventilation path. As a result, the gas entry path can be effectively controlled, preventing the problem of some gas entering from the liquid supply recess and occupying the liquid supply path, affecting the liquid supply and ultimately causing the heating element to burn.

[0018] In the following description, specific details such as particular systems, structures, and techniques are presented for illustrative purposes, not for limitation, so that embodiments of the present invention may be fully understood.

Furthermore, in other circumstances, detailed descriptions of well-known systems, apparatus, electrical circuits, and methods are omitted so as not to hinder the description of the present invention by unnecessary details.

[0019] Referring to Figures 1 to 11, an electronic heating atomization assembly 1 in one embodiment of the present invention includes a substrate 11, a liquid guide member 12 for transporting liquid, and a heating member 13 for heating and atomizing the liquid in the liquid guide member 12. The heating member 13 is in contact with the liquid guide member 12. The substrate 11 is provided with a housing chamber 116, and the liquid guide member 12 and the heating member 13 are provided within the housing chamber 116. A liquid supply recess 111 is provided on the outside of the substrate 11. The liquid supply recess 111 forms a liquid supply opening 1111 that is open to the outside. The substrate 11 is provided with at least two liquid supply capillary holes 112 located within the liquid supply recess 111, which connect the liquid supply recess 111 and the housing chamber 116. As a result, liquid from outside the substrate 11 enters the housing chamber 116 through the liquid supply recess 111 and the liquid supply capillary holes 112 and comes into contact with the liquid guide member 12. Typically, the fluid guide member 12 is made of a porous material having numerous micropores. The fluid guide member 12 absorbs the liquid and transmits it to the heating element 13. The heating element 13 heats the liquid and atomizes it by generating heat when an electric current is passed through it. The fluid supply opening 1111 is used to control the fluid supply area, thereby preventing leakage of the atomizing liquid due to an excessively large fluid supply area. The base body 11 is provided with a ventilation path 115 that connects the outside to the containment chamber 116. The ventilation path 115 is provided at a location other than the fluid supply recess 111.

[0020] Referring to Figures 14 and 16, when the electro-heated atomization assembly 1 is used in an electro-heated atomization device, the electro-heated atomization device is usually provided with a liquid storage tank 21 for storing liquid 3. The liquid storage tank 21 communicates with the liquid supply opening 1111 of the electro-heated atomization assembly 1. Liquid 3 is supplied through the liquid supply opening 1111, the liquid supply recess 111 and Liquid supply capillary hole 112 The liquid enters the containment chamber 116 via the ventilation path 115 and comes into contact with the liquid guide member 12. The liquid guide member 12 absorbs the liquid 3 and transmits it to the heating element 13. The heating element 13 is energized to heat the atomizing liquid 3. When the liquid 3 in the storage tank 21 is consumed, outside air enters the storage tank 21 via the ventilation path 115, maintaining the air pressure balance between the storage tank 21 and the outside.

[0021] Referring to Figures 15 and 17, the electronic heating atomization assembly 1 is designed with a liquid supply capillary hole 112 in the liquid supply recess 111. Due to the tension of the liquid 3 within the liquid supply capillary hole 112 and the small micropores of the liquid guide member 12 itself, the resistance of outside air entering the liquid storage tank 21 from the liquid supply recess 111 is increased. In addition, a ventilation path 115 is provided at a location other than the liquid supply recess 111. As a result, the resistance of outside air entering the liquid storage tank 21 from the liquid supply recess 111 is high, while the resistance of air entering the liquid storage tank 21 from the ventilation path 115 is low, causing air to tend to enter the liquid storage tank 21 from the ventilation path 115. This allows for effective control of the gas entry path, preventing the problem of some gas entering from the liquid supply recess 111 and occupying the liquid supply path, affecting the liquid supply, and ultimately causing the heating element 13 to burn.

[0022] The liquid supply recess 111 is provided in the side wall 110 of the base body 11. The liquid supply recess 111 forms a liquid supply opening 1111 on one side of the side wall 110 in the extension direction. Furthermore, the liquid supply recess 111 also opens and forms a second opening 1112 on one side of the side wall 110 in the thickness direction. However, the second opening 1112 is not used for liquid supply. The liquid supply capillary hole 112 penetrates the side wall 110 in the thickness direction of the side wall 110, thereby connecting the liquid supply recess 111 and the storage chamber 116. With this design, when the electronic heating atomization assembly 1 is used in an electronic heating atomization device, the housing 2 of the device covers the second opening 1112, but leaves the liquid supply opening 1111 open, allowing it to communicate with the liquid storage tank 21. Therefore, the liquid 3 in the liquid storage tank 21 enters the liquid supply recess 111 through the liquid supply opening 1111. In the embodiment shown in Figure 4, the liquid supply recess 111 has a liquid supply opening 1111 on one side in the vertical direction and a second opening 1112 on one side in the horizontal direction. The liquid supply capillary hole 112 penetrates the side wall 110 of the base 11 in the horizontal direction.

[0023] Referring to Figures 3 and 4, the liquid supply recess 111 has a recess depth U in the wall thickness direction of the side wall 110 that is smaller than the width V. And / or, the liquid supply recess 111 has a recess depth U in the wall thickness direction of the side wall 110 that is smaller than the size W in the direction of the liquid supply opening 1111. Designed in this way, when the electro-heated atomization assembly 1 is used in an electro-heated atomization device, the housing 2 of the device covers the second opening 1112, but leaves the liquid supply opening 1111 open to communicate with the liquid storage tank 21. The inner surface of the housing 2 or the inner surface of the sealing member 14 and the liquid supply recess 111 define a liquid supply capillary groove 23 (see Figure 15). The liquid supply capillary groove 23 is a narrow, elongated region of a certain length, and referring to Figures 15 and 17, it performs the following functions.

[0024] (1) The capillary force formed by the tension of the liquid 3 in the liquid supply capillary groove 23 makes it more difficult for air to enter at the location of the liquid supply capillary hole 112. In other words, when the air pressure inside the liquid storage tank 21 of the electronic heating atomizer decreases and outside air tries to enter the liquid storage tank 21, it is necessary to push aside the liquid 3 at the location of the liquid supply capillary hole 112. However, since the liquid supply capillary groove 23 formed at the location of the liquid supply capillary hole 112 has greater resistance, it is not possible to push aside the liquid 3 at the liquid supply capillary hole 112 unless the air pressure difference between the inside and outside of the liquid storage tank 21 becomes even larger. In contrast, the liquid film at the opening of the ventilation path 115 (see Figure 16) is more easily broken. Therefore, the gas path during ventilation can be controlled more effectively, and air will mainly be ventilated from the ventilation path 115. This prevents the problem of the core burning, which can occur when gas enters the storage tank 21 from the liquid supply capillary groove 23 instead of the designated ventilation path 115, occupying the liquid supply path and resulting in improper liquid supply during operation.

[0025] (2) The liquid supply capillary groove 23 can rapidly discharge gas from within the liquid 3 due to the tension of the liquid 3, thereby avoiding the formation of bubbles that may affect the liquid supply.

[0026] (3) The liquid supply capillary groove 23 ensures heating and atomization of a small amount of liquid 3 in the liquid supply capillary groove 23 even when the electronic heating atomization assembly 1 is upside down (normally, the electronic heating atomization assembly 1 is in a state where the liquid supply capillary hole 112 faces upward, and the device's liquid storage tank 21 is located above the electronic heating atomization assembly 1). Therefore, even when the user is lying down during use, the liquid 3 in the liquid supply capillary groove 23 can supply a constant amount of atomized vapor, and when the electronic heating atomization assembly 1 returns to its normal position (where the liquid supply capillary hole 112 faces upward), the liquid supply capillary groove 23 is rapidly filled with liquid 3 again.

[0027] Referring to Figure 4, the liquid supply recess 111 has a recess depth U of 1 mm or less in the wall thickness direction of the side wall 110. Due to this size, when the electronic heating atomization assembly 1 is used in an e-cigarette, the size of the liquid supply capillary groove 23 formed in the narrow direction (i.e., the size in the wall thickness direction of the side wall 110 of the base 11) is 1 mm or less, so that appropriate tension is formed in the liquid 3. This better realizes the technical effect of preventing some gas from entering from the liquid supply recess 111 and occupying the liquid supply path.

[0028] Referring to Figures 5 to 11, the base body 11 is provided with protruding segmented ribs 113 within the liquid supply recess 111. The segmented ribs 113 extend from near the liquid supply opening 1111 in a direction away from the liquid supply opening 1111, partitioning the at least two liquid supply capillary holes 112 and dividing the liquid supply recess 111 into at least two liquid supply paths 1131 that communicate with the liquid supply capillary holes 112. By dividing one large liquid supply recess 111 into multiple small liquid supply paths 1131 with the segmented ribs, the capillary tension in the liquid supply paths 1131 is increased, thereby increasing the capillary tension of the liquid 3 and preventing it from being easily destroyed by gas.

[0029] Referring to Figures 1 to 3, the electronic heating atomization assembly 1 includes a sealing member 14. The sealing member 14 is provided on the outside of the base body 11, and segmented ribs 113 support the inner surface of the sealing member 14. Typically, the sealing member 14 is made of an elastically deformable material, so that the liquid supply capillary holes 112 are not obstructed by the deformation of the sealing member 14, thereby preventing a loss of liquid supply area.

[0030] Referring to Figures 8 to 11, the divided rib 113 is provided with a communication notch 1132 at one end away from the liquid supply opening 1111, which connects adjacent liquid supply paths 1131. As a result, communication is formed between each of the divided small liquid supply paths 1131, allowing the liquid 3 to communicate and flow between each of the small liquid supply paths 1131, ensuring smooth liquid supply. Guaranteed .

[0031] Referring to Figure 5, the liquid supply capillary hole 112 includes a first partial hole 1121 and a second partial hole 1122 that communicate with each other. The first partial hole 1121 extends from near the liquid supply opening 1111 in a direction away from the liquid supply opening 1111. As a result, the liquid supply capillary hole 112 has an "inverted T" shape. Since one end of the first partial hole 1121 is close to the liquid supply opening 1111, the liquid 3 in the portion of the liquid supply opening 1111 can be better guided and dispersed to each portion of the liquid supply capillary hole 112. This ensures that the liquid 3 makes balanced contact with the liquid guide member 12 in the containment chamber 116.

[0032] Referring to Figures 6 and 7, the base body 11 is located within the liquid supply recess 111, from near the liquid supply opening 1111 to a distance from the liquid supply opening 1111. direction A fluid guide groove 114 is provided extending from the fluid guide groove 114. The fluid guide groove 114 communicates with the fluid supply capillary hole 112 and is used to ensure smooth fluid supply through the fluid supply capillary hole 112. Such a design can be used in the structure of a narrow electro-heated atomizing assembly 1. When the fluid supply capillary groove 23, defined by the fluid supply recess 111 and the housing 2 or sealing member 14 of the device, is small due to spatial constraints, such a design can achieve smooth fluid supply.

[0033] Referring to Figures 12 to 17, an electronic atomizing apparatus according to one embodiment of the present invention includes a housing 2 and the electronic atomizing assembly 1 provided inside the housing 2. The inner surface of the housing 2 and the liquid supply recess 111 define a liquid supply capillary groove 23. The liquid supply opening 1111 is the opening of the liquid supply capillary groove 23. The housing 2 is provided with a liquid storage tank 21. The liquid storage tank 21 communicates with the liquid supply opening 1111. The electronic atomizing assembly 1 includes a sealing member 14 to prevent leakage of the liquid 3 in the liquid storage tank 21. The sealing member 14 is provided between the base 11 and the housing 2. The housing 2 is provided with a ventilation path 22. The ventilation path 22 communicates with the electronic atomizing assembly 1. As a result, the atomized vapor generated by the electronic atomizing assembly 1 flows out of the apparatus through the ventilation path 22.

[0034] The base body 11 is provided with a protruding segmented rib 113 within the liquid supply recess 111. The segmented rib 113 extends from near the liquid supply opening 1111 in a direction away from the liquid supply opening 1111, partitioning the at least two liquid supply capillary holes 112 and dividing the liquid supply recess 111 into at least two liquid supply paths 1131 that communicate with the liquid supply capillary holes 112. The segmented rib 113 supports the inner surface of the housing 2 or the sealing member 14. This prevents the liquid supply capillary holes 112 from being obscured and the liquid supply area from being impaired due to deformation of the housing 2 or the sealing member 14.

[0035] Refer to Figure 17, electronic heating atomization device By designing a liquid supply capillary hole 112 in the liquid supply recess 111, the tension of the liquid 3 within the liquid supply capillary hole 112 and the small micropores of the liquid guide member 12 itself increase the resistance of outside air entering the liquid storage tank 21 from the liquid supply recess 111. In addition, a ventilation path 115 is provided at locations other than the liquid supply recess 111. As a result, the resistance of outside air entering the liquid storage tank 21 from the liquid supply recess 111 is high, while the resistance of air entering the liquid storage tank 21 from the ventilation path 115 is low, causing air to tend to enter the liquid storage tank 21 from the ventilation path 115. This allows for effective control of the gas entry path, preventing the problem of some gas entering from the liquid supply recess 111 and occupying the liquid supply path, affecting the liquid supply and ultimately causing the heating element 13 to burn.

[0036] Referring to Figures 14 and 16, the liquid storage tank 21 in the electronic heating atomizer communicates with the liquid supply opening 1111 of the electronic heating atomization assembly 1. The liquid 3 is supplied to the liquid supply opening 1111, the liquid supply recess 111 and Liquid supply capillary hole 112 The liquid enters the containment chamber 116 via the ventilation path 115 and comes into contact with the liquid guide member 12. The liquid guide member 12 absorbs the liquid 3 and transmits it to the heating element 13. The heating element 13 is energized to heat the atomizing liquid 3. When the liquid 3 in the storage tank 21 is consumed, outside air enters the storage tank 21 via the ventilation path 115, maintaining the air pressure balance between the storage tank 21 and the outside.

[0037] Referring to Figures 15 and 17, the electronic heating atomization assembly 1 is designed with a liquid supply capillary hole 112 in the liquid supply recess 111. Due to the tension of the liquid 3 within the liquid supply capillary hole 112 and the small micropores of the liquid guide member 12 itself, the resistance of outside air entering the liquid storage tank 21 from the liquid supply recess 111 is increased. In addition, a ventilation path 115 is provided at a location other than the liquid supply recess 111. As a result, the resistance of outside air entering the liquid storage tank 21 from the liquid supply recess 111 is high, while the resistance of air entering the liquid storage tank 21 from the ventilation path 115 is low, causing air to tend to enter the liquid storage tank 21 from the ventilation path 115. This allows for effective control of the gas entry path, preventing the problem of some gas entering from the liquid supply recess 111 and occupying the liquid supply path, affecting the liquid supply, and ultimately causing the heating element 13 to burn.

[0038] The liquid supply recess 111 is provided in the side wall 110 of the base body 11. The liquid supply recess 111 forms a liquid supply opening 1111 on one side of the side wall 110 in the extension direction. Furthermore, the liquid supply recess 111 also opens and forms a second opening 1112 on one side of the side wall 110 in the thickness direction. However, the second opening 1112 is not used for liquid supply. The liquid supply capillary hole 112 penetrates the side wall 110 in the thickness direction of the side wall 110, thereby connecting the liquid supply recess 111 and the storage chamber 116. With this design, when the electronic heating atomization assembly 1 is used in an electronic heating atomization device, the housing 2 of the device covers the second opening 1112, but leaves the liquid supply opening 1111 open, allowing it to communicate with the liquid storage tank 21. Therefore, the liquid 3 in the liquid storage tank 21 enters the liquid supply recess 111 through the liquid supply opening 1111. In the embodiment shown in Figure 4, the liquid supply recess 111 has a liquid supply opening 1111 on one side in the vertical direction and a second opening 1112 on one side in the horizontal direction. The liquid supply capillary hole 112 penetrates the side wall 110 of the base 11 in the horizontal direction.

[0039] Referring to Figures 3 and 4, the liquid supply recess 111 has a recess depth U in the wall thickness direction of the side wall 110 that is smaller than the width V. And / or, the liquid supply recess 111 has a recess depth U in the wall thickness direction of the side wall 110 that is smaller than the size W in the direction of the liquid supply opening 1111. Designed in this way, when the electro-heated atomization assembly 1 is used in an electro-heated atomization device, the housing 2 of the device covers the second opening 1112, but leaves the liquid supply opening 1111 open to communicate with the liquid storage tank 21. The inner surface of the housing 2 or the inner surface of the sealing member 14 and the liquid supply recess 111 define a liquid supply capillary groove 23 (see Figure 15). The liquid supply capillary groove 23 is a narrow, elongated region of a certain length, and referring to Figures 15 and 17, it performs the following functions.

[0040] (1) The capillary force formed by the tension of the liquid 3 in the liquid supply capillary groove 23 makes it more difficult for air to enter at the location of the liquid supply capillary hole 112. In other words, when the air pressure inside the liquid storage tank 21 of the electronic heating atomizer decreases and outside air tries to enter the liquid storage tank 21, it is necessary to push aside the liquid 3 at the location of the liquid supply capillary hole 112. However, since the liquid supply capillary groove 23 formed at the location of the liquid supply capillary hole 112 has greater resistance, it is not possible to push aside the liquid 3 at the liquid supply capillary hole 112 unless the air pressure difference between the inside and outside of the liquid storage tank 21 becomes even larger. In contrast, the liquid film at the opening of the ventilation path 115 (see Figure 16) is more easily broken. Therefore, the gas path during ventilation can be controlled more effectively, and air will mainly be ventilated from the ventilation path 115. This prevents the problem of core burning that can occur due to irregular liquid supply during operation, as the gas enters the storage tank 21 from the liquid supply capillary groove 23 rather than from the designated ventilation path 115, thus occupying the liquid supply path.

[0041] (2) The liquid supply capillary groove 23 can rapidly discharge gas from within the liquid 3 due to the tension of the liquid 3, thereby avoiding the formation of bubbles that may affect the liquid supply.

[0042] (3) The liquid supply capillary groove 23 ensures heating and atomization of a small amount of liquid 3 in the liquid supply capillary groove 23 even when the electronic heating atomization assembly 1 is upside down (normally, the electronic heating atomization assembly 1 is in a state where the liquid supply capillary hole 112 faces upward, and the device's liquid storage tank 21 is located above the electronic heating atomization assembly 1). Therefore, even when the user is lying down during use, the liquid 3 in the liquid supply capillary groove 23 can supply a constant amount of atomized vapor, and when the electronic heating atomization assembly 1 returns to its normal position (where the liquid supply capillary hole 112 faces upward), the liquid supply capillary groove 23 is rapidly filled with liquid 3 again.

[0043] The foregoing description represents only preferred embodiments of the present invention and does not limit it. Various modifications, combinations, and variations of the present invention are possible for those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., implemented within the spirit and principles of the present invention are all included within the scope of the claims.
