Description

Technical Field

[0001] The present application relates to the technical field of atomization devices, and in particular to an electronic atomization device and an oil supply system thereof. Background Art

[0002] The electronic atomization device using aerosol generating oil includes an oil storage chamber, which is used to store the aerosol generating oil. Since some regions have clear requirements on the size of the oil storage chamber of the product, and a too large oil storage chamber will lead to uneven oil supply and easy oil leakage, the current oil volume in the oil storage chamber is usually less than 5 ml. In use, in order to improve the user experience, the electronic atomization device is usually also equipped with an oil replenishing bottle. After the aerosol generating oil in the oil storage chamber is used up, the oil storage chamber can be replenished with the oil replenishing bottle, but currently it is usually refilled by manual operation of the oil replenishing bottle. Since the oil storage chamber and the oil replenishing bottle are relatively airtight, the oil storage chamber is affected by the pressure in the oil storage chamber and the oil replenishing bottle when replenishing the oil, resulting in a slow refilling speed of the oil storage chamber.

DETAILED DESCRIPTION

[0035] The present application is further described in detail below by specific embodiments in conjunction with the accompanying drawings. Wherein similar elements in different embodiments adopt associated similar element numbers. In the following embodiments, many detailed descriptions are intended to enable the present application to be better understood. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, and methods. In some cases, some operations related to the present application are not shown or described in the specification, in order to avoid the core part of the present application being overwhelmed by too much description, and for those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0036] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations. At the same time, the steps or actions in the method description can also be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a required sequence, unless otherwise specified that a certain sequence must be followed.

[0037] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0038] It should be noted that the conduction, communication and interconnection described in the present application are not limited to empty channels through which aerosol generating oil can pass, but also include channels filled with porous materials through which aerosol generating oil can pass.

[0039] In response to the problem of slow oil refilling in the oil storage chamber of current electronic atomization devices, the oil supply system in the present application pumps the aerosol-generated oil in the oil refilling container to the oil storage chamber through a pumping mechanism, and sets an air path between the oil storage chamber and the oil refilling container to balance the air pressure in the oil storage chamber and the oil refilling container, thereby achieving rapid oil refilling to the oil storage chamber.

[0040] In one embodiment, please refer to Figure 1 The electronic atomization device includes an oil replenishing container 2, an oil supply system and a power supply component, wherein the power supply component includes a power supply 1, and the oil replenishing container 2 is used to store aerosol generating oil. The oil supply system includes an atomizer 3, an oil channel 4, an air channel 5 and a pumping mechanism 6.

[0041] The atomizer 3 includes an atomizer shell 31 and an atomizer core 32. The atomizer shell 31 has an oil storage chamber 311 therein. The oil storage chamber 311 is used to communicate with the atomizer core 32, and the aerosol generating oil enters the atomizer core 32. The atomizer core 32 is used to atomize the aerosol generating oil into an aerosol. The oil passage 4 communicates the oil storage chamber 311 with the oil replenishing container 2, and the aerosol generating oil enters the oil storage chamber 311 from the oil replenishing container 2.

[0042] The pumping mechanism 6 is used to provide power to transport the aerosol generating oil in the oil replenishing container 2 to the oil storage chamber 311. The air path channel 5 connects the oil storage chamber 311 and the oil replenishing container 2. During the process of transporting the aerosol generating oil, the air path channel 5 can exhaust air from the oil storage chamber 311 to the oil replenishing container 2, so that the aerosol generating oil quickly enters the oil storage chamber 311.

[0043] In the electronic atomization device of the present application, the oil supply system transports the aerosol generated oil in the oil replenishing container 2 to the oil storage chamber 311 through the oil path channel 4 by means of the pumping mechanism 6. During the process of transporting the aerosol generated oil, the gas in the oil storage chamber 311 is discharged into the oil replenishing container 2, thereby allowing the aerosol generated oil to quickly and smoothly enter the oil storage chamber 311.

[0044] In the present application, the atomizer 3 can be provided in any feasible manner, for example, the atomizer core 32 can be fixed in the atomizer shell 31, and the atomizer core 32 is always connected to the oil storage chamber 311. For another example, the atomizer 3 also includes a partition separating the atomizer core 32 from the oil storage chamber 311, and the partition can be opened as needed. When the partition separates the atomizer core 32 from the oil storage chamber 311, the atomizer core 32 is disconnected from the oil storage chamber 311, and the aerosol-generating oil cannot enter the atomizer core 32, which can reduce the leakage of the aerosol-generating oil; in one embodiment, the partition can be a partition sleeve that is movably sleeved on the outer periphery of the atomizer core 32.

[0045] Regarding the structure of the atomizer core 32, since the structure of the atomizer core 32 is a relatively mature prior art, this application only briefly describes the structure of the atomizer core 32. The atomizer core 32 includes a heating element 321 for heating the atomized aerosol to generate oil. The atomizer core 32 has an atomization channel 322 for the aerosol to flow, and at least part of the heating element 321 is in the atomization channel 322. The atomizer core 32 also includes an oil guide member 323, which is a porous material, such as porous oil-guiding cotton or microporous ceramics. The atomizer core 32 includes an atomizer core shell 324, and the atomization channel 322 is in the atomizer core shell 324. The atomizer core shell 324 has an oil through hole 3241 that connects the atomization channel 322 and the oil storage chamber 311. The oil guide 323 is located between the atomizer core shell 324 and the heating element 321, and is used to guide the aerosol generating oil that enters the atomizer core shell 324 through the oil hole 3241 to the heating element 321. The heating element 321 atomizes the aerosol generating oil into an aerosol by heating. Figure 1, the oil guide 323 is cylindrical, and the heating element 321 is located inside the oil guide 323. In one embodiment, the heating element 321 is a spiral heating wire, and the spiral heating wire extends along the atomization channel 322. In another embodiment, please refer to Figure 1 The heating element 321 is a conductive metal grid, and one side of the conductive metal grid is attached to the oil guide element 323.

[0046] In one embodiment, please refer to Figure 1 The oil storage chamber 311 is located between the atomizer core shell 324 and the atomizer shell 31, and the atomizer core 32 is arranged in the center, so that the oil storage chamber 311 is an annular chamber. In addition to the annular chamber form, the atomizer core 32 and the oil storage chamber 311 can also be arranged side by side, and the oil storage chamber 311 is located beside the atomizer core 32.

[0047] Regarding the form of the pumping mechanism 6, in one embodiment, the pumping mechanism 6 is an oil pump. Specifically, the oil pump can be either a micro oil pump or a peristaltic pump.

[0048] In one embodiment, please refer to Figure 1 , the pumping mechanism 6 is arranged on the oil passage 4, and is used to pump the aerosol generating oil from the oil replenishing container 2 into the oil storage chamber 311, and the air passage 5 is used to balance the air pressure in the oil storage chamber 311 and the oil replenishing container 2. Specifically, in one embodiment, the oil supply system includes an oil supply pipe 7, and the channel in the oil supply pipe 7 forms at least a part of the oil passage 4. The pumping mechanism 6 is connected to the oil supply pipe 7. In another embodiment, the pumping mechanism 6 is on the air passage 5, and the pumping mechanism 6 increases the pressure in the oil replenishing container 2 by forcibly discharging the gas from the oil storage chamber 311 into the oil replenishing container 2, thereby pressing the aerosol generating oil in the oil replenishing container 2 into the oil storage chamber 311. Specifically, in one embodiment, the oil supply system includes an air pipe 8, and the channel in the air pipe 8 forms at least a part of the air passage. The pumping mechanism 6 is connected to the air pipe 8. That is to say, there are two ways of providing power for the pumping mechanism 6 in the present application, one of which is to extract the aerosol-generating oil from the oil replenishing container 2 and pump it into the oil storage chamber 311, and the other is to extract air from the oil storage chamber 311 and pump it into the oil replenishing container 2, thereby squeezing the aerosol-generating oil in the oil replenishing container 2 into the oil storage chamber 311.

[0049] Further, in one embodiment, please refer to Figure 1, the oil passage 4 includes a first oil passage opening 41 and a second oil passage opening 42, the first oil passage opening 41 is in communication with the oil storage chamber 311, and the second oil passage opening 42 is in communication with the oil replenishing container 2, and the gas passage 5 includes a first gas passage opening 51 and a second gas passage opening 52, the first gas passage opening 51 is in communication with the oil storage chamber 311, and the second gas passage opening 52 is in communication with the oil replenishing container 2. When the aerosol in the atomizer core 32 is sucked, the first oil passage opening 41 is lower than the first gas passage opening 51, so that the aerosol-generated oil in the oil storage chamber 311 is not easy to enter the gas passage 5. In some other embodiments, when the aerosol in the atomizer core 32 is sucked, the first oil passage opening 41 is level with the first gas passage opening 51. In some other embodiments, when the aerosol in the atomizer core 32 is sucked, the first oil passage opening 41 may also be higher than the first gas passage opening 51.

[0050] Further, in one embodiment, please refer to Figure 1 When the aerosol in the atomizer core 32 is sucked, the first oil path opening 41 is higher than the oil hole 3241, so that the first oil path opening 41 is not easily blocked by the aerosol generated oil in the oil storage chamber 311. In some other embodiments, when the aerosol in the atomizer core 32 is sucked, the first oil path opening 41 can also be flush with the oil hole 3241, and of course the first oil path opening 41 can also be lower than the oil hole 3241.

[0051] Regarding the structure of the atomizer housing 31, in one embodiment, please refer to Figure 1 The atomizer core 32 is located in the atomizer shell 31 , the oil storage cavity 311 is an annular cavity located between the atomizer core 32 and the shell, the atomizer shell 31 includes an outer annular cavity wall 312 spaced opposite to the atomizer core 32 , and the first oil path opening 41 and the first gas path opening 51 are both located on the outer annular cavity wall 312 .

[0052] The atomizer housing 31 has an oil circuit connector 313 connected to the oil supply pipe 7 and an air circuit connector 314 connected to the air pipe 8, and both the oil circuit connector 313 and the air circuit connector 314 are located on the outer annular cavity wall 312. Both the oil circuit connector 313 and the air circuit connector 314 protrude outward, which can facilitate the connection between the oil circuit connector 313 and the oil supply pipe 7, and also facilitate the connection between the air circuit connector 314 and the air pipe 8.

[0053] Specifically, in one embodiment, please refer to Figure 1 The atomizer shell 31 includes a shell 315 and a shell seat 316, and the shell seat 316 is fixed to the bottom of the shell 315. The atomizer 3 includes a sealing seat 33 in the shell 315, and the sealing seat 33 is sealed with the shell 315, and the outer annular cavity wall 312 is on the shell 315.

[0054] Further, in one embodiment, please refer to Figure 1The oil replenishing container 2 includes an oil replenishing bottle 21, a bottle cap 22, and a bottle cap oil pipe 23 disposed on the bottle cap 22. The bottle cap 22 covers the bottle mouth of the oil replenishing bottle 21, and the oil passage 4 is connected to the bottle cap oil pipe 23. The bottle cap oil pipe 23 extends from the bottle mouth to the bottom of the oil replenishing bottle 21, so that the aerosol generating oil can enter the bottle cap oil pipe 23. Specifically, in one embodiment, the bottle cap oil pipe 23 extends to the bottom of the oil replenishing bottle 21, and the bottle cap oil pipe 23 has a connecting groove 231 connected to the bottom of the oil replenishing bottle 21, or the end face of the bottle cap oil pipe 23 and the oil replenishing bottle 21 have a gap, so that the aerosol generating oil can enter. In one embodiment, the bottle cap 22 and the bottle cap oil pipe 23 are integrally formed.

[0055] Further, in one embodiment, please refer to Figure 1 The bottle cap 22 has a bottle cap air hole 221 , the air path channel 5 is in communication with the bottle cap air hole 221 , and the opening of the bottle cap air hole 221 toward the oil replenishing bottle 21 is located at the top of the oil replenishing bottle 21 .

[0056] When the aerosol generating oil needs to be delivered, the aerosol generating oil is sucked out of the oil replenishing bottle 21 from the bottle cap oil pipe 23 extending to the bottom, and at the same time, the air in the oil storage cavity 311 enters the oil replenishing bottle 21 from the air pipe 8 to maintain the air pressure balance of the oil replenishing bottle 21.

[0057] Specifically, in one embodiment, please refer to Figure 1 The bottle cap 22 is buckled on the oil replenishing bottle 21 , and a sealing silica gel 24 is provided between the oil replenishing bottle 21 and the bottle cap 22 , and the sealing silica gel 24 seals the oil replenishing bottle 21 .

[0058] Furthermore, in one embodiment, the electronic atomization device includes an oil level detection component, which is used to detect the aerosol generating oil in the oil storage chamber 311. The oil supply system includes a control system, which is connected to the oil level detection component so as to receive the detection information of the oil level detection component. The control system is connected to the pumping mechanism 6 so as to control the operation of the pumping mechanism 6.

[0059] In one embodiment, please refer to Figure 1The oil level detection element includes a first detection electrode 91 and a second detection electrode 92, wherein the first detection electrode 91 includes a first portion 911 exposed in the oil storage chamber 311, and the second detection electrode 92 includes a second portion 921 exposed in the oil storage chamber 311. When the aerosol is sucked, the lowest position of the first portion 911 is higher than the lowest position of the second portion 921. Since the aerosol generating oil has the property of being conductive, when the aerosol generating oil is sufficient, the first detection electrode 91 and the second detection electrode 92 are connected. When the aerosol generating oil is insufficient, the first portion 911 is first separated from the aerosol generating oil, and the first detection electrode 91 and the second detection electrode 92 are disconnected. At this time, the control system can identify the state of the first detection electrode 91 and the second detection electrode 92, and judge that the aerosol generating oil is insufficient, and control the pumping mechanism 6 to replenish the aerosol generating oil to the oil storage chamber 311.

[0060] In one embodiment, please refer to Figure 1 , the power source 1 is a battery cell, and the battery cell supplies power to the pumping mechanism 6 and the atomizing core 32. In one embodiment, please refer to Figure 1 The control system includes a PCBA assembly 10 , and the battery cell provides electrical energy for the PCBA assembly 10 .

[0061] In one embodiment, please refer to Figure 1 The heating element 321 includes a first working electrode 3211 and a second working electrode 3212 , and both the first working electrode 3211 and the second working electrode 3212 are connected to a control system so that the control system can control the operation of the heating element 321 .

[0062] The first detection electrode 91 and the second detection electrode 92 are both connected to a control system, so that the control system can know the on and off states of the first detection electrode 91 and the second detection electrode 92 .

[0063] In one embodiment, please refer to Figure 1, the control system needs to collect the resistance signal between the first detection electrode 91 and the second detection electrode 92 as the basis for judging whether the atomizer 3 has enough aerosol generating oil remaining. When it is identified that the remaining amount of aerosol generating oil is sufficient, the user issues a work instruction, and the control system outputs electric energy to the working electrode in time, and the atomizer 3 works normally. When it is identified that the remaining amount of aerosol generating oil is insufficient, the control system determines that the atomizer 3 needs to add aerosol generating oil, and prompts the user to add aerosol generating oil to the atomizer 3. The control system controls the pumping mechanism 6 to work, and the pumping mechanism 6 pumps the aerosol generating oil in the oil replenishment container 2 to the oil storage chamber 311 of the atomizer 3. After pumping a certain amount of aerosol generating oil, the aerosol generating oil in the oil storage chamber 311 is sufficient, and the control system controls the pumping mechanism 6 to stop working, and the pumping mechanism 6 stops delivering the aerosol generating oil. The signal transmitted by the detection electrode to the control system will be identified as sufficient aerosol generating oil remaining. At this time, if the user issues a work instruction, the atomizer 3 can work normally.
