Abstract
Description
Technical Field
[0001] This invention relates to the field of electronic heating atomization, and in particular to an electronic heating atomization component and device. Background Technology
[0002] Electronic heating atomizing devices transform liquid into gas by electrically heating an atomizing liquid. They primarily use electricity to heat the liquid to its boiling point, creating atomized vapor that mixes with air to form an aerosol. Currently, they are mainly used in the e-cigarette industry, but there is also a trend towards expansion into beauty and medical fields. Electronic heating atomizing devices typically include a liquid guide, a heating element, and a liquid reservoir. During use, the liquid guide conducts liquid from the reservoir to the heating element. The heating element, when energized, heats the liquid, atomizing it. As the liquid in the reservoir is consumed, more space is created. This extra space has a lower air pressure than the external atmospheric pressure, allowing outside air to enter the reservoir through the gap connecting it to the outside. This air often obstructs the liquid guide, causing poor liquid flow and affecting the liquid supply. Summary of the Invention

[0004] The technical solution adopted by the present invention to solve its technical problem includes: providing an electronic heating atomizing component, comprising a substrate, a liquid guiding component for conducting liquid, and a heating component for heating and atomizing the liquid in the liquid guiding component. The substrate is provided with a receiving cavity, the liquid guiding component and the heating component are disposed in the receiving cavity, and a liquid inlet recess is provided on the outer side of the substrate, the liquid inlet recess forming an outwardly open liquid inlet opening. The substrate is provided with at least two liquid inlet capillary holes at a position in the liquid inlet recess communicating with the receiving cavity, so that liquid outside the substrate can enter the receiving cavity from the liquid inlet recess and the liquid inlet capillary holes; the substrate is provided with a ventilation channel communicating with the outside and the receiving cavity, the ventilation channel being located outside the liquid inlet recess.
[0005] Preferably, the liquid inlet recess is provided on the side wall of the substrate, and the liquid inlet recess forms the liquid inlet opening on one side of the side wall in the extension direction of the side wall. The liquid inlet capillary penetrates the side wall along the thickness direction of the side wall.
[0006] Preferably, the depth of the liquid inlet recess along the wall thickness direction is less than its width, and / or the depth of the liquid inlet recess along the wall thickness direction is less than its size along the direction of the liquid inlet opening.
[0007] Preferably, the depth of the liquid inlet recess along the thickness direction of the side wall is less than or equal to 1 mm.
[0008] Preferably, the substrate has raised partition ribs in the liquid inlet recess, the partition ribs extending in a direction from near the liquid inlet opening to away from the liquid inlet opening, separating the at least two liquid inlet capillaries, and dividing the liquid inlet recess into at least two liquid inlet channels leading to the liquid inlet capillaries.
[0009] Preferably, the system includes a seal, which is disposed on the outside of the substrate, and the partition rib supports the seal.
[0010] Preferably, the end of the separator rib away from the liquid inlet opening is provided with a connecting notch for connecting to the adjacent liquid inlet channel.
[0011] Preferably, the liquid inlet capillary includes a first portion of the hole and a second portion of the hole that are interconnected, wherein the first portion of the hole extends in a direction from near the liquid inlet opening to away from the liquid inlet opening.
[0012] Preferably, the substrate has a liquid guiding groove in the liquid inlet recess extending from near the liquid inlet opening to away from the liquid inlet opening, and the liquid guiding groove communicates with the liquid inlet capillary.
[0013] The technical solution adopted by the present invention to solve its technical problem includes: providing an electronic heating atomizing device, comprising a housing and the aforementioned electronic heating atomizing component disposed in the housing, wherein the inner surface of the housing and the liquid inlet recess define a liquid inlet capillary narrow groove, the liquid inlet opening is the opening of the liquid inlet capillary narrow groove, the housing is provided with a liquid storage chamber, the liquid storage chamber is connected to the liquid inlet opening; the electronic heating atomizing component includes a sealing element for preventing liquid leakage from the liquid storage chamber, the sealing element being disposed between the base and the housing; the housing is provided with a venting channel, the venting channel being connected to the electronic heating atomizing component, so that the atomized vapor generated by the electronic heating atomizing component flows out from the venting channel. Preferably, the base is provided with a raised partition rib in the liquid inlet recess, the partition rib extending along a direction from near the liquid inlet opening to away from the liquid inlet opening, separating the at least two liquid inlet capillaries, dividing the liquid inlet recess into at least two liquid inlet channels leading to the liquid inlet capillaries; the partition rib supports the inner surface of the housing or the sealing element.
[0014] The technical solution of this invention has at least the following beneficial effects: The electronic heating atomizing component and device are designed with a liquid inlet capillary at the liquid inlet recess. By utilizing the surface tension of the liquid in the liquid inlet capillary and the small micropore characteristics of the liquid guide itself, the resistance of external air entering the liquid storage chamber from the liquid inlet recess is increased. At the same time, an air exchange channel is provided at a location other than the liquid inlet recess. Since the resistance of external air entering the liquid storage chamber from the liquid inlet recess is high, while the resistance of entering the liquid storage chamber from the air exchange channel is low, air tends to enter the liquid storage chamber from the air exchange channel. This effectively controls the gas entry path and prevents some gas from entering from the liquid inlet recess and occupying the liquid supply channel, which could affect the liquid supply or even cause the heating element to burn.

However, those skilled in the art will understand that the invention can be implemented in other embodiments without these specific details.

[0037] See Figure 1-11An electronic heating atomizing assembly 1 according to one embodiment of the present invention includes a substrate 11, a liquid guiding member 12 for conducting liquid, and a heating member 13 for heating and atomizing the liquid in the liquid guiding member 12. The heating member 13 is in contact with the liquid guiding member 12. The substrate 11 is provided with a receiving cavity 116, in which the liquid guiding member 12 and the heating member 13 are disposed. A liquid inlet recess 111 is located on the outer side of the substrate 11, forming an outwardly open liquid inlet opening 1111. At least two liquid inlet bristles are provided on the substrate 11 within the liquid inlet recess 111, connecting the liquid inlet recess 111 and the receiving cavity 116. The fine holes 112 allow liquid outside the substrate 11 to enter the receiving cavity 116 from the liquid inlet recess 111 and the liquid inlet capillary 112, and come into contact with the liquid guide 12. The liquid guide 12 is usually made of a porous material with numerous micropores. The liquid guide 12 absorbs and conducts the liquid to the heating element 13. The heating element 13 is energized and heats up the liquid to atomize it. 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. The substrate 11 is provided with a ventilation channel 115 that connects the outside to the receiving cavity 116. The ventilation channel 115 is located outside the liquid inlet recess 111.
[0038] See Figure 14 and 16 When the electronic heating atomizing component 1 is applied in an electronic heating atomizing device, the electronic heating atomizing device is usually provided with a liquid storage tank 21 for storing liquid 3. The liquid storage tank 21 is connected to the liquid inlet opening 1111 of the electronic heating atomizing component 1. Liquid 3 enters the receiving cavity 116 through the liquid inlet opening 1111, the liquid inlet recess 111 and the liquid inlet hole, and comes into contact with the liquid guide 12. The liquid guide 12 absorbs and conducts the liquid 3 to the heating element 13. The heating element 13 is energized to heat and atomize the liquid 3, consuming the liquid 3 in the liquid storage tank 21. 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.
[0039] See Figure 15 and 17 The electronic heating atomizing component 1 is designed with a liquid inlet capillary 112 at the liquid inlet recess 111. By utilizing the surface tension of the liquid 3 within the liquid inlet capillary 112 and the small micropores of the liquid guide 12 itself, the resistance of external air entering the liquid storage chamber 21 from the liquid inlet recess 111 is increased. At the same time, an air exchange channel 115 is provided outside the liquid inlet recess 111. Since the resistance of external air entering the liquid storage chamber 21 from the liquid inlet recess 111 is high, while the resistance of air entering the liquid storage chamber 21 from the air exchange channel 115 is low, air tends to enter the liquid storage chamber 21 from the air exchange channel 115. This effectively controls the gas entry path and prevents some 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.
[0040] A liquid inlet recess 111 is provided on the sidewall 110 of the base 11. The liquid inlet recess 111 forms a liquid inlet opening 1111 on one side of the sidewall 110 extending in the direction of extension. Simultaneously, the liquid inlet recess 111 also opens on one side of the sidewall 110 in the thickness direction, forming a second opening 1112, but the second opening 1112 is not used for liquid inlet. A liquid inlet capillary pore 112 penetrates the sidewall 110 along the thickness direction to connect the liquid inlet recess 111 with the receiving cavity 116. With this design, when the electronic heating atomizing component 1 is applied in an electronic heating atomizing device, the device housing 2 covers the second opening 1112, leaving the liquid inlet opening 1111 to communicate with the liquid storage tank 21. The liquid 3 in the liquid storage tank 21 enters the liquid inlet recess 111 through the liquid inlet opening 1111. Figure 4 In one embodiment, the liquid inlet recess 111 forms a liquid inlet opening 1111 on one longitudinal side and a second opening 1112 on one transverse side, and the liquid inlet capillary 112 transversely penetrates the sidewall 110 of the substrate 11.
[0041] See Figure 3-4 The depth U of the inlet recess 111 along the wall thickness direction of the sidewall 110 is less than the width V, and / or the depth U of the inlet recess 111 along the wall thickness direction of the sidewall 110 is less than the dimension W along the direction of the inlet opening 1111. With this design, when the electronic heating atomizing component 1 is applied in an electronic heating atomizing device, the housing 2 of the device covers the second opening 1112, leaving the inlet opening 1111 to communicate with the liquid storage tank 21. The inner side of the housing 2 or the inner side of the seal 14 defines the inlet capillary narrow groove 23 with the inlet recess 111 (see Figure 15 The inlet capillary narrow channel 23 is a relatively narrow and elongated region of a certain length. Its function is: (See below) Figure 15 and 17 ① The capillary force formed by the tension of the liquid 3 in the narrow capillary channel 23 makes it more difficult for air to enter at the capillary orifice 112. That is to say, when the air pressure in the liquid storage chamber 21 of the electronic heating atomizing device decreases, the outside air needs to push the liquid 3 at the capillary orifice 112 aside to enter the liquid storage chamber 21. However, the narrow capillary channel 23 formed at the capillary orifice 112 has greater resistance, and a greater pressure difference is required between the inside and outside of the liquid storage chamber 21 to push the liquid 3 at the capillary orifice 112 aside. On the contrary, the liquid film at the opening of the ventilation channel 115 (see Figure 16① It allows for better breakthrough, thus enabling more effective control of the gas path during ventilation. Air is mainly exchanged through the ventilation channel 115, preventing gas from entering the liquid storage chamber 21 through the inlet capillary narrow channel 23 instead of the predetermined ventilation channel 115, thus avoiding the problem of clogging the core due to poor liquid supply during operation; ② Due to the surface tension of the liquid 3, the inlet capillary narrow channel 23 can quickly discharge the gas in the liquid 3, avoiding the formation of air bubbles that affect the liquid flow; ③ When the electronic heating atomizing component 1 is inverted, the inlet capillary narrow channel 23... (Normally, the electronic heating atomizing component 1 is in the normal operating state with the liquid inlet capillary 112 facing upwards, and the liquid storage tank 21 of the device is located above the electronic heating atomizing component 1.) This also ensures that there is a small amount of liquid 3 in the liquid inlet capillary narrow channel 23 for heating and atomization. When the user is lying down, the liquid 3 in the liquid inlet capillary narrow channel 23 can also supply a certain amount of atomized steam. When the user is placed upright again (with the electronic heating atomizing component 1 in the state of liquid inlet capillary 112 facing upwards), the liquid inlet capillary narrow channel 23 will quickly fill with liquid 3 again.
[0042] See Figure 4 The depth U of the inlet recess 111 along the wall thickness direction of the sidewall 110 is less than or equal to 1 mm. This dimension ensures that when the electronic heating atomizing component 1 is applied to an electronic cigarette, the narrow dimension of the aforementioned inlet capillary narrow groove 23 (that is, the dimension along the wall thickness direction of the sidewall 110 of the substrate 11) is less than or equal to 1 mm, which allows the liquid 3 to form a suitable tension and better achieve the technical effect of preventing some gas from entering from the inlet recess 111 and occupying the liquid supply channel.
[0043] See Figure 5-11 The substrate 11 has raised dividing ribs 113 in the liquid inlet recess 111. The dividing ribs 113 extend from near the liquid inlet opening 1111 to away from the liquid inlet opening 1111, separating the at least two liquid inlet capillaries 112 and dividing the liquid inlet recess 111 into at least two liquid inlet channels 1131 leading to the liquid inlet capillaries 112. The dividing ribs divide a large liquid inlet recess 111 into multiple small liquid inlet channels 1131, which is used to increase the capillary tension at the liquid inlet channel 1131, so that the liquid 3 has a greater capillary tension and is not easily broken by gas.
[0044] See Figure 1-3 The electronic heating atomizing component 1 includes a seal 14, which is located on the outside of the base 11. The partition rib 113 supports the inner surface of the seal 14. Since the seal 14 is usually made of an elastic and deformable material, it can prevent the liquid inlet capillary 112 from being blocked by the deformation of the seal 14 and thus losing the liquid inlet area.
[0045] See Figure 8-11The end of the dividing rib 113 away from the liquid inlet opening 1111 is provided with a connecting notch 1132 for connecting adjacent liquid inlet channels 1131, so that the various small liquid inlet channels 1131 separated can be connected, and the liquid 3 can flow in a connected manner between the various small liquid inlet channels 1131, ensuring smooth liquid supply.
[0046] See Figure 5 The liquid inlet capillary 112 includes a first part hole 1121 and a second part hole 1122 that are interconnected. The first part hole 1121 extends from near the liquid inlet opening 1111 to away from the liquid inlet opening 1111, making the liquid inlet capillary 112 in an "inverted T" shape. Since one end of the first part 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 evenly in contact with the liquid guide 12 in the receiving cavity 116.
[0047] Referring to 6-7, the substrate 11 has a liquid guiding groove 114 extending from near the liquid inlet opening 1111 to away from the liquid inlet opening 1111 in the liquid inlet recess 111. The liquid guiding groove 114 communicates with the liquid inlet capillary 112 to ensure smooth liquid supply to the liquid inlet capillary 112. This design can be used in narrower electronic heating atomizing assembly 1 structures. When space constraints limit the liquid inlet recess 111 and the narrow liquid inlet capillary groove 23 defined by the housing 2 or seal 14 of the device, smooth liquid supply can be achieved through this design.
[0048] See Figure 12-17 According to one embodiment of the present invention, the electronic heating atomizing device includes a housing 2 and the aforementioned electronic heating atomizing component 1 disposed in the housing 2. The inner surface of the housing 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. The housing 2 is provided with a liquid storage chamber 21, which is connected to the liquid inlet opening 1111. The electronic heating atomizing component 1 includes a sealing member 14 for preventing liquid 3 from leaking out of the liquid storage chamber 21. The sealing member 14 is disposed between the base 11 and the housing 2. The housing 2 is provided with a vent 22, which is connected to the electronic heating atomizing component 1, so that the atomized vapor generated by the electronic heating atomizing component 1 can flow out of the device through the vent 22.
[0049] The substrate 11 has raised partition ribs 113 in the liquid inlet recess 111. The partition ribs 113 extend from near the liquid inlet opening 1111 to away from the liquid inlet opening 1111, separating the at least two liquid inlet capillaries 112 and dividing the liquid inlet recess 111 into at least two liquid inlet channels 1131 leading to the liquid inlet capillaries 112. The partition ribs 113 support the inner surface of the housing 2 or the seal 14, which can prevent the housing 2 or the seal 14 from deforming and blocking the liquid inlet capillaries 112, thus preventing the loss of liquid inlet area.
[0050] See Figure 17 The electronic heating atomizing component device is designed with a liquid inlet capillary 112 at the liquid inlet recess 111. By utilizing the surface tension of the liquid 3 within the liquid inlet capillary 112 and the small micropores of the liquid guide 12 itself, the resistance of external air entering the liquid storage chamber 21 from the liquid inlet recess 111 is increased. At the same time, an air exchange channel 115 is provided outside the liquid inlet recess 111. Since the resistance of external air entering the liquid storage chamber 21 from the liquid inlet recess 111 is high, while the resistance of air entering the liquid storage chamber 21 from the air exchange channel 115 is low, air tends to enter the liquid storage chamber 21 from the air exchange channel 115. This effectively controls the gas entry path and prevents some 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.
[0051] See Figure 14 and 16 The liquid storage chamber 21 in the electronic heating atomizing device is connected to the liquid inlet opening 1111 of the electronic heating atomizing component 1. The liquid 3 enters the receiving cavity 116 through the liquid inlet opening 1111, the liquid inlet recess 111 and the liquid inlet hole, and comes into contact with the liquid guide 12. The liquid guide 12 absorbs and conducts the liquid 3 to the heating element 13. The heating element 13 is energized to heat and atomize the liquid 3, consuming the liquid 3 in the liquid storage chamber 21. External air enters the liquid storage chamber 21 through the ventilation channel 115, so that the liquid storage chamber 21 maintains air pressure balance with the outside.
[0052] See Figure 15 and 17 The electronic heating atomizing component 1 is designed with a liquid inlet capillary 112 at the liquid inlet recess 111. By utilizing the surface tension of the liquid 3 within the liquid inlet capillary 112 and the small micropores of the liquid guide 12 itself, the resistance of external air entering the liquid storage chamber 21 from the liquid inlet recess 111 is increased. At the same time, an air exchange channel 115 is provided outside the liquid inlet recess 111. Since the resistance of external air entering the liquid storage chamber 21 from the liquid inlet recess 111 is high, while the resistance of air entering the liquid storage chamber 21 from the air exchange channel 115 is low, air tends to enter the liquid storage chamber 21 from the air exchange channel 115. This effectively controls the gas entry path and prevents some 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.
[0053] A liquid inlet recess 111 is provided on the sidewall 110 of the base 11. The liquid inlet recess 111 forms a liquid inlet opening 1111 on one side of the sidewall 110 extending in the direction of extension. Simultaneously, the liquid inlet recess 111 also opens on one side of the sidewall 110 in the thickness direction, forming a second opening 1112, but the second opening 1112 is not used for liquid inlet. A liquid inlet capillary pore 112 penetrates the sidewall 110 along the thickness direction to connect the liquid inlet recess 111 with the receiving cavity 116. With this design, when the electronic heating atomizing component 1 is applied in an electronic heating atomizing device, the device housing 2 covers the second opening 1112, leaving the liquid inlet opening 1111 to communicate with the liquid storage tank 21. The liquid 3 in the liquid storage tank 21 enters the liquid inlet recess 111 through the liquid inlet opening 1111. Figure 4 In one embodiment, the liquid inlet recess 111 forms a liquid inlet opening 1111 on one longitudinal side and a second opening 1112 on one transverse side, and the liquid inlet capillary 112 transversely penetrates the sidewall 110 of the substrate 11.
[0054] See Figure 3-4 The depth U of the inlet recess 111 along the wall thickness direction of the sidewall 110 is less than the width V, and / or the depth U of the inlet recess 111 along the wall thickness direction of the sidewall 110 is less than the dimension W along the direction of the inlet opening 1111. With this design, when the electronic heating atomizing component 1 is applied in an electronic heating atomizing device, the housing 2 of the device covers the second opening 1112, leaving the inlet opening 1111 to communicate with the liquid storage tank 21. The inner side of the housing 2 or the inner side of the seal 14 defines the inlet capillary narrow groove 23 with the inlet recess 111 (see Figure 15 The inlet capillary narrow channel 23 is a relatively narrow and elongated region of a certain length.

(Normally, the electronic heating atomizing component 1 is in the normal operating state with the liquid inlet capillary 112 facing upwards, and the liquid storage tank 21 of the device is located above the electronic heating atomizing component 1.) This also ensures that there is a small amount of liquid 3 in the liquid inlet capillary narrow channel 23 for heating and atomization. When the user is lying down, the liquid 3 in the liquid inlet capillary narrow channel 23 can also supply a certain amount of atomized steam. When the user is placed upright again (with the electronic heating atomizing component 1 in the state of liquid inlet capillary 112 facing upwards), the liquid inlet capillary narrow channel 23 will quickly fill with liquid 3 again.
