Description

Technical Field

[0001] This invention relates to the field of electronic heating atomization technology, and in particular to an electronic heating atomization unit and device with a ventilated microgroove structure. Background Technology

[0002] Electronic heating atomization technology utilizes electrical heating to heat an atomizing liquid, causing it to reach its boiling point and produce an aerosol formed by mixing steam and air. Electronic heating atomization devices typically include a heating element and a liquid guiding element. The liquid guiding element absorbs and conducts the liquid, usually made of microporous material. Its working principle involves the atomizing liquid being conducted from the reservoir to the heating element through the capillary pores inside the liquid guiding element. When power is supplied to the heating element, the heating element heats up due to the resistance heating effect, heating the atomizing liquid to its boiling point, producing atomized steam. This atomized steam mixes with the air entering the atomizer to form an aerosol, commonly known as smoke. The airflow entering the electronic heating atomization device carries the smoke outwards.

[0003] Currently, electronic heating atomization devices are widely used in the field of e-cigarettes. They mainly atomize the liquid into a gas through electronic atomization devices. The atomizing liquid is mainly composed of substances such as propylene glycol, glycerol, nicotine, and flavorings. Propylene glycol and glycerol are mainly used as carriers for nicotine and flavorings. After being heated and atomized, it is inhaled by users to satisfy people's smoking needs. Because the temperature is low during atomization, fewer harmful substances are produced compared to traditional cigarettes.

[0004] Existing electronic atomizing devices typically include an atomizing component, which usually comprises numerous structural parts. This means a complex assembly process. Furthermore, the internal components must be airtight to prevent leakage into the liquid reservoir. This is crucial to prevent liquid from leaking out of the device and mixing with the vapor. For e-cigarettes, leaked droplets in the vapor can cause dryness in the mouth when inhaling. As the atomizing liquid in the reservoir is consumed, the pressure within the reservoir changes. These pressure fluctuations affect the stability of the liquid supply to the atomizer core. Therefore, the reservoir needs ventilation to maintain pressure balance. This necessitates an electronic heating atomizing unit that balances both sealing and ventilation capabilities. Summary of the Invention

[0041] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of the invention.

In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods are omitted so as not to obscure the description of the invention with unnecessary detail.

[0042] See Figure 1-6 An electronic heating atomizing unit 1 with a ventilated microgroove structure according to one embodiment of the present invention includes a main body 11, a first sealing member 12, and an atomizing core 15. The main body 11 includes a base 112 and a protrusion 111 provided on the main body 11. The protrusion 111 is provided with a protrusion vent hole 1111 that connects the inside and outside for airflow to pass through. The main body 11 is provided with a liquid inlet hole 1112 that connects the outside and the protrusion vent hole 1111 for allowing liquid to enter the protrusion vent hole 1111 from the outside of the protrusion 111. The atomizing core 15 is provided in the protrusion vent hole 1111. The atomizing core 15 includes a heating member 151 for heating and atomizing the liquid and a liquid guiding member 152 for conducting the liquid from the liquid inlet hole 1112 to the heating member 151.

[0043] The first sealing element 12 is installed at the end of the protrusion 111 where the protrusion vent 1111 is provided, covering the outer side of the protrusion 111 and the inner side of the protrusion vent 1111. The first sealing element 12 is provided with a sealing element vent 124. The atomizing core vent 153, the protrusion vent 1111 and the sealing element vent 124 are connected to each other so that the airflow entering the atomizing core vent 153, the protrusion vent 1111 and the sealing element vent 124 can carry the smoke generated by the atomizing core 15.

[0044] A ventilation microgroove structure is provided between the first seal 12 and the protrusion 111, allowing airflow to pass from the outside of the protrusion 111 to the vent hole 1111 of the protrusion. The ventilation microgroove structure is configured such that gas can pass through but liquid cannot pass through the hole. The ventilation microgroove structure is provided on the protrusion 111 and / or the first seal 12. When the electronic heating atomizing unit 1 is working, the liquid storage tank 21 for storing liquid is located outside the unit. Liquid enters from the outside of the protrusion 111 of the main body 11 through the liquid inlet 1112 and contacts the liquid guide 152 of the atomizing core 15. The liquid guide 152 conducts the liquid to the heating element 151 for heating to form smoke. The smoke is formed in the ventilation channel formed by the vent hole 1111 of the protrusion, the vent hole 153 of the atomizing core, and the vent hole 124 of the inner ring wall 122 of the first sealing element 12. The airflow carries the smoke out of the electronic heating atomizing unit 1 through the ventilation channel. During this process, as the liquid is consumed, the air pressure in the liquid storage tank 21 decreases. Then, the gas enters the liquid storage tank 21 from the proposed vent hole through the ventilation micro-groove structure, realizing the ventilation of the liquid storage tank 21, balancing the air pressure of the liquid storage tank 21, and ensuring the stability of the liquid supply to the atomizing core 15. Because of the tiny size of the ventilated microchannel structure, gas can pass through, but liquid in the liquid storage tank 21 cannot, thus ensuring both airtightness and the ventilation function of the liquid storage tank 21.

[0045] The electronic heating atomizing unit 1 has several advantages. First, it has a simple structure with fewer parts, making it easy to assemble and reducing the need for sealing between parts. Second, it achieves sealing by cooperating with the protrusion 111 of the main body 11 and the first sealing element 12, as well as the ventilation microgroove structure. At the same time, it also ensures the ventilation function of the liquid storage chamber 21. As the liquid in the liquid storage chamber 21 is consumed, air can smoothly enter the liquid storage chamber 21 through the ventilation microgroove structure, balancing the air pressure in the liquid storage chamber 21. This prevents gas from entering the liquid storage chamber 21 from the liquid guide 152 of the atomizing core 15, occupying the micropores in the liquid guide 152, affecting the liquid guiding efficiency of the liquid guide 152, and ensuring the stability of the liquid supply to the atomizing core 15.

[0046] Preferably, the first sealing element 12 includes an inner ring wall 122, an outer ring wall 121 surrounding the inner ring wall 122, and a connecting wall 123 connecting the end of the outer ring wall 121 and the end of the inner ring wall 122. A vent hole 124 is defined on the side of the inner ring wall 122 facing away from the outer ring wall 121. The outer ring wall 121, inner ring wall 122, and connecting wall 123 define a gap 125 open facing away from the connecting wall 123. One end of the protrusion 111 with the protrusion vent hole 1111 is embedded in the gap 125 of the first sealing element 12. The outer ring wall 121 and connecting wall 123 cover the protrusion 111. On the outer side, the inner ring wall 122 covers the inner side of the protruding vent hole 1111. The protruding vent hole 1111, the atomizing core vent hole 153 and the sealing vent hole 124 of the inner ring wall 122 of the first sealing member 12 communicate to form a ventilation channel for airflow. In the gap 125 of the protruding part 111, a ventilation micro-groove structure is provided between the first sealing member 12 and the protruding part 111 to allow airflow from the outside of the protruding part 111 to the protruding vent hole 1111. The ventilation micro-groove structure is designed so that gas can pass through but liquid cannot. The ventilation micro-groove structure is provided on the protruding part 111 and / or the first sealing member 12.

[0047] Preferably, the protrusion 111 includes an outer top surface 1113 and a side surface 1114 around the top wall that is not parallel to the top surface 1113. A vent hole 1111 is formed on the top surface 1113. The outer ring wall 121 of the first sealing member 12 covers the side surface 1114 of the protrusion 111, the connecting wall 123 covers the top surface 1113 of the protrusion 111, and the inner ring wall 122 covers the inner side of the vent hole 1111. The venting microgroove structure includes a first microgroove 131 between the side surface 1114 and the outer ring wall 121 of the protrusion 111, and a microgroove 131 between the top surface 1113 and the connecting wall 123. The second microgroove 132 between 23 and the third microgroove 133 located between the inner side of the vent hole 1111 of the protrusion and the inner ring wall 122 are connected. The first microgroove 131 is located on the side surface 1114 of the protrusion 111 and / or on the side of the inner ring wall 122 facing the protrusion 111. The second microgroove 132 is located on the top surface 1113 of the protrusion 111 and / or on the side of the connecting wall 123 facing the protrusion 111. The third microgroove 133 is located on the inner side of the vent hole 1111 of the protrusion and / or on the side of the inner ring wall 122 facing the protrusion 111.

[0048] More preferably, the first microgroove 131 extends from a position away from the top surface 1113 of the protrusion 111 toward the top surface 1113, the second microgroove 132 extends from a position away from the vent hole 1111 of the protrusion toward the vent hole 1111 of the protrusion, and the third microgroove 133 extends from the top surface 1113 of the protrusion 111 toward a direction away from the top surface 1113.

[0049] exist Figure 1-6 In one embodiment, the first microgroove 131 is provided on the side 1114 of the protrusion 111, and the third microgroove 133 is provided on the first seal 12. Preferably, the second microgroove 132 is provided on the first seal 12.

[0050] Preferably, the electronic heating atomizing unit 1 includes a gas permeable element 14. The gas permeable element 14 is disposed in the gap 125 of the first seal 12 and located between the first seal 12 and the protrusion 111, so that the airflow in the ventilation micro-groove structure can flow through the gas permeable element 14. The purpose of the gas permeable element 14 is to make the liquid storage tank 21 have a certain negative pressure, which can further prevent liquid from leaking from the liquid guide element 152. When the negative pressure is too low and affects the performance of the liquid guide element 152 during operation, the gas can first enter the liquid storage tank 21 from the ventilation micro-groove structure, thereby achieving the effect of balancing the gas pressure. More preferably, the protrusion 111 includes an outer top surface 1113 and a side surface 1114 around the top wall that is not parallel to the top surface 1113. The vent hole 1111 of the protrusion is formed on the top surface 1113. The outer ring wall 121 of the first seal 12 covers the side surface 1114 of the protrusion 111, the connecting wall 123 covers the top surface 1113 of the protrusion 111, and the inner ring wall 122 covers the inner side of the vent hole 1111 of the protrusion. The venting member 14 is annular and is arranged around the vent hole 1111 of the protrusion, and is disposed between the top surface 1113 of the protrusion 111 and the connecting wall 123 of the first seal 12.

[0051] The liquid guiding component 152 of the atomizing core 15 can be made of fibrous cloth or other shapes, or it can be made of porous ceramic, porous glass or other porous materials. The atomizing core vent 153 is provided on the liquid guiding component 152. The wall thickness of the liquid guiding component 152 is 0.5-3mm. If it is too thin, it will easily cause leakage of atomized liquid; if it is too thick, it will easily cause insufficient liquid supply during continuous operation. The wall thickness of the venting component 14 is 0.1-1mm. Preferably, the wall thickness of the liquid guiding component 152 is greater than the wall thickness of the venting component 14.

[0052] The breathable component 14 can be made of porous material. Preferably, the breathable component 14 is porous ceramic, porous fiber, or a liquid-barrier breathable membrane that isolates liquid while allowing gas to pass through. The principle of breathable materials with microporous structures, such as porous ceramic and porous fiber, is that when the porous ceramic or porous fiber is filled with atomized liquid, it forms an oil film. When the pressure difference between the inside and outside of the liquid storage chamber 21 reaches a certain threshold, air can break through this membrane and enter the liquid storage chamber 21, thus increasing the pressure in the liquid storage chamber 21. The principle of the liquid-barrier breathable membrane is that it has a microporous structure at a microscopic level. Utilizing the order-of-magnitude difference in volume between gas molecules and liquid and dust particles, it allows gas molecules to pass through while preventing liquid and dust from passing through, thereby achieving the purpose of liquid-barrier breathability. For example, a waterproof breathable membrane that can prevent water molecules from passing through while allowing gas to pass through, or an oil-barrier breathable membrane that can prevent oil molecules from passing through while allowing gas molecules to pass through.

[0053] More preferably, the atomizing core vent 153, the protruding vent 1111, and the sealing vent 124 are arranged in the same direction to form a straight-through ventilation channel; the inner side of the atomizing core vent 153 is the atomizing surface that generates smoke, and the liquid guiding member 152 contacts the inner side of the protruding vent 1111 and covers the liquid inlet 1112. Even more preferably, the atomizing core vent 153 is provided on the liquid guiding member 152, and the heating member 151 is arranged in contact with the liquid guiding member 152 and heats the liquid in the liquid guiding member 152 to form smoke in the atomizing core vent 153. More preferably, the base 112 of the main body 11 is provided with an air inlet 1121, which is connected to the vent hole 1111 of the protrusion. Thus, the flow of liquid and smoke is achieved through a relatively simple structure. Specifically, the liquid outside the electronic heating atomizing unit 1 contacts the liquid guide 152 through the liquid inlet 1112. The liquid guide 152 conducts the liquid to the heating element 151 for heating and generating smoke in the atomizing core vent hole 153. The airflow outside the electronic heating atomizing unit 1 enters the ventilation channel formed by the vent hole 1111 of the protrusion, the vent hole 153 of the atomizing core, and the vent hole 124 of the inner ring wall 122 of the first sealing element 12 through the air inlet 1121, and carries the smoke out to the outside.

[0054] Preferably, the electronic heating atomizing unit 1 includes an electrode 16, and the heating element 151 includes a heating part 1511 that generates heat when energized for heating the liquid from the liquid guide 152, and a lead wire 1512 connected to the heating part 1511. The lead wire 1512 is disposed in the main body 11, and an electrode hole 1122 is provided on the base 112. The electrode 16 is electrically connected to the lead wire 1512 and is disposed in the electrode hole 1122 with an interference fit. Thus, the interference fit plays a role in preventing liquid leakage and preventing liquid from seeping out of the electronic heating atomizing unit 1 along the lead wire 1512 of the heating element 151.

[0055] See Figure 7-11 An electronic heating atomizing device according to one embodiment of the present invention includes a housing 2 and the aforementioned electronic heating atomizing unit 1. The housing 2 is provided with an air outlet 22 and a liquid storage tank 21 for storing liquid. The electronic heating atomizing unit 1 is connected to the housing 2. The liquid storage tank 21 is connected to the liquid inlet 1112 of the protrusion 111. The air outlet 22 is connected to the sealing vent 124 of the first sealing member 12 and is sealed by the first sealing member 12. The electronic heating atomizing device has an air inlet 1121 that connects to the outside and the vent 1111 of the protrusion.

[0056] The second sealing element 3 has an opening on the outer shell 2, and the electronic heating atomizing unit 1 is installed into the opening. The electronic heating atomizing device includes a second sealing element 3 for forming a seal between the base 112 and the outer shell 2.

[0057] When the electronic heating atomizing device is working, the liquid in the storage tank 21 enters through the liquid inlet 1112 on the outside of the protrusion 111 of the main body 11 and comes into contact with the liquid guide 152 of the atomizing core 15. The liquid guide 152 conducts the liquid to the heating element 151 for heating to form smoke. The smoke is formed in the ventilation channel formed by the vent hole 1111 of the protrusion, the vent hole 153 of the atomizing core and the vent hole 124 of the inner ring wall 122 of the first sealing element 12. The airflow carries the smoke out of the electronic heating atomizing device through the ventilation channel. During this process, as the liquid is consumed, the air pressure in the storage tank 21 decreases. Then, the gas enters the storage tank 21 from the proposed vent through the ventilation micro-groove structure, realizing the ventilation of the storage tank 21, balancing the air pressure of the storage tank 21, and ensuring the stability of the liquid supply to the atomizing core 15. Because of the tiny size of the ventilated microchannel structure, gas can pass through, but liquid in the liquid storage tank 21 cannot, thus ensuring both airtightness and the ventilation function of the liquid storage tank 21.

[0058] The functions of each part of the electronic heating atomization unit 1 and the electronic heating atomization device are as follows:

[0059] Liquid inlet 1112: controls the size of the contact area between the liquid outside the electronic heating atomizing unit 1 and the liquid guiding component 152. A larger contact area results in more liquid entering, while a smaller contact area results in less liquid entering.

[0060] Protrusion 111: Mainly columnar, with a protrusion vent 1111 inside to supply the atomizing core 15 for installation, and a liquid inlet 1112 on the side wall; its main function is to provide support strength for the atomizing core 15, while the size of the liquid inlet 1112 controls the contact area between the liquid and the liquid guide 152.

[0061] Ventilation microchannel structure: used as a channel for external air to enter the liquid storage tank 21, mainly to balance the air pressure;

[0062] Air inlet: The channel through which gas enters the electronically heated atomizing unit 1; its size controls the amount of air entering.

[0063] Electrode hole 1122: Exposed on the outer surface of the electronic heating atomizing device, used for electrical connection with the power supply unit to supply power to the device;

[0064] Storage compartment 21: mainly a storage unit for atomizing liquid;

[0065] The base 112 of the main body 11, together with the liquid storage tank 21, forms a sealed space to store the atomizing liquid;

[0066] First sealing element 12: There is a connection between the air outlet 22 of the outer shell 2 and the protrusion 111 of the main body 11 of the electronic heating atomizing unit 1, forming a seal to prevent liquid from leaking from the connection gap between the air outlet 22 and the protrusion 111.

[0067] Second sealing element 3: A seal is formed at the connection between the opening of the outer shell 2 and the base 112 of the body 11 of the electronic heating atomizing unit 1 to prevent liquid from leaking from the connection gap between the opening and the base 112.

[0068] Atomizing Core 15: This is the core of the electronically heated atomizing unit 1, which can transform liquid into aerosol.

[0069] Electrode 16: Used for electrical connection with an external power supply unit to supply power to the electronic heating atomizing device.

[0070] The electronic heating atomizing device has a simple structure and few components. It mainly consists of two parts: the outer shell 2 and the main body 11 of the electronic heating atomizing unit 1, as well as some functional auxiliary components forming the second sealing element 3, and the atomizing core 15, electrode 16, and venting element 14 of the electronic heating atomizing unit 1. Therefore, it is relatively easy to assemble. In addition, the cooperation between the protrusion 111 of the main body 11 and the first sealing element 12, as well as the ventilation micro-groove structure, achieves sealing while also taking into account the ventilation function of the liquid storage chamber 21. As the liquid in the liquid storage chamber 21 is consumed, air can smoothly enter the liquid storage chamber 21 through the ventilation micro-groove structure, balancing the air pressure in the liquid storage chamber 21. This prevents gas from entering the liquid storage chamber 21 from the liquid guide 152 of the atomizing core 15, occupying the micropores in the liquid guide 152, affecting the liquid guiding efficiency of the liquid guide 152, and ensuring the stability of the liquid supply to the atomizing core 15.

For those skilled in the art, the present invention can have various modifications, combinations, and variations.
