Description

Technical Field

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

[0002] The electronic atomization device includes an atomizer, and the atomizer has an oil storage chamber for storing 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, easy oil leakage and other problems, the current oil volume in the oil storage chamber is usually less than 5 ml. During 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 oil through the oil replenishing bottle. However, it is not easy to find out in time after the aerosol generating oil in the oil storage chamber is used up. It will only be discovered when the user continues to use it and cannot generate aerosol. This can easily cause the atomization core in the atomizer to dry burn, reducing the service life of the atomizer. Utility Model Content

[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 order to solve the problem that the oil storage chamber of the current electronic atomization device does not detect the need for oil refilling in time, the present application adds a detection electrode to the atomizer to detect the aerosol generating oil in the oil storage chamber. When the aerosol generating oil in the oil storage chamber is insufficient, it can be detected and replenished in time.

[0040] An electronic atomization device, please refer to Figure 1 The electronic atomization device includes a power supply component and an atomizer 1, and the power supply component supplies power to the atomizer 1. Specifically, in one embodiment, the power supply component includes a power supply 2, and the power supply component supplies power to the atomizer 1 through the power supply 2.

[0041] In one embodiment, please refer to Figure 1The atomizer 1 includes an atomizer shell 11, an atomizer core 12, a first detection electrode 13, and a second detection electrode 14. The atomizer shell 11 has an oil storage chamber 111, and the oil storage chamber 111 is used to store aerosol generating oil. The atomizer core 12 has an atomization channel 121, and the atomization channel 121 is used to communicate with the oil storage chamber 111, so that the aerosol generating oil enters the atomization channel 121 and the generated aerosol flows.

[0042] The atomization core 12 includes a heating element 122 . At least a portion of the heating element 122 is located in the atomization channel 121 . The heating element 122 is used to heat and atomize the aerosol generating oil entering the atomization channel 121 .

[0043] The first detection electrode 13 is inserted into the oil storage chamber 111, and the portion of the first detection electrode 13 exposed in the oil storage chamber 111 is the first contact detection portion 131. The second detection electrode 14 is inserted into the oil storage chamber 111, and the portion of the second detection electrode 14 exposed in the oil storage chamber 111 is the second contact detection portion 141. Both the first contact detection portion 131 and the second contact detection portion 141 are used to contact the aerosol generating oil. When the atomizer 1 is inhaled, the lowest point of at least one of the first contact detection portion 131 and the second contact detection portion 141 is higher than the lowest point of the oil storage chamber 111.

[0044] In order to detect the amount of aerosol generating oil in the oil storage chamber 111, the present application utilizes the conductive property of the aerosol generating oil, and detects the amount of aerosol generating oil by detecting the conductive parameters of the electrode and the aerosol generating oil. When the first contact detection part 131 and the second contact detection part 141 are in contact with the aerosol generating oil at the same time, the first contact detection part 131 and the second contact detection part 141 can be connected. When the liquid level of the aerosol generating oil in the oil storage chamber 111 drops, at least one of the first contact detection part 131 and the second contact detection part 141 is not in contact with the aerosol generating oil, the first contact detection part 131 and the second contact detection part 141 cannot be connected. In this way, the atomizer 1 can detect the liquid level of the aerosol generating oil in the oil storage chamber 111 using the electrical parameters between the first contact detection part 131 and the second contact detection part 141, so that it can be discovered in time when the aerosol generating oil in the oil storage chamber 111 needs to be replenished. In order to avoid dry burning of the atomizer core 12, the lowest point of at least one of the first contact detection part 131 and the second contact detection part 141 of the present application is higher than the lowest point 1111 of the oil storage chamber 111. In this way, when the first contact detection part 131 and the second contact detection part 141 cannot be conducted, a portion of the aerosol generating oil can still be retained in the oil storage chamber 111 to avoid dry burning of the atomizer core 12.

[0045] When the atomizer 1 is being sucked, the lowest point 1111 of the oil storage chamber 111 is the lowest position of the bottom surface of the oil storage chamber 111. The first contact detection portion 131 is in the oil storage chamber 111, and the lowest point 1311 of the first contact detection portion 131 is the lowest position when the atomizer 1 is being sucked. Similarly, the second contact detection portion 141 is also in the oil storage chamber 111, and the lowest point 1411 of the second contact detection portion 141 is the lowest position when the atomizer 1 is being sucked.

[0046] Specifically, in one embodiment, the lowest point 1311 of the first contact detection portion 131 is higher than the lowest point 1111 of the oil storage chamber 111 , and the lowest point 1411 of the second contact detection portion 141 is at the same height as the lowest point 1111 of the oil storage chamber 111 .

[0047] Regarding the structure of the atomizer core 12, in one embodiment, please refer to Figure 1 The atomizer core 12 includes an atomizer core shell 123 and an oil guide member 124 in the atomizer core shell 123, and the atomization channel 121 is in the atomizer core shell 123. The atomizer core shell 123 has an oil hole 1231, and the oil hole 1231 is connected to the oil storage chamber 111, so that the aerosol generating oil enters the atomizer core shell 123. The oil guide member 124 is located between the heating element 122 and the atomizer core shell 123, and is used to guide the aerosol generating oil entering the atomizer core shell 123 to the heating element 122. The oil guide member 124 is a porous material, such as porous oil-guiding cotton or microporous ceramics. The atomizer has a nozzle 17, and the nozzle hole 171 of the nozzle 17 is connected to the atomization channel 121.

[0048] The heating element 122 atomizes the aerosol generating oil into aerosol by heating. Figure 1 The heating element 122 can be in any feasible manner, for example, the heating element 122 can be a spiral heating wire, a heating cylinder formed by bending a metal mesh plate, or a heating plate. Figure 1 The oil guide 124 is cylindrical, the heating element 122 is located inside the oil guide 124, and the heating element 122 is a heating cylinder formed by bending a metal mesh plate. In another embodiment, the heating element 122 is a planar conductive metal mesh, one side of which is attached to the oil guide 124, and there is a gap between the planar conductive metal mesh and the inner wall of the atomization channel 121 to allow airflow to pass through.

[0049] Regarding the first detection electrode 13 and the second detection electrode 14, in one embodiment, please refer to Figure 1, the first detection electrode 13 and the second detection electrode 14 are both made of conductive materials. The atomizer 1 includes a base 15, the base 15 is fixed to the bottom of the atomizer shell 11, and the first detection electrode 13 and the second detection electrode 14 are arranged on the base 15. In one embodiment, the first detection electrode 13 and the second detection electrode 14 are both needle-shaped. In some other embodiments, the first detection electrode 13 and the second detection electrode 14 can be conductive metal sheets, so that the detection electrode has a larger area inside the atomizer, which is more conducive to the accurate collection of signals.

[0050] In one embodiment, please refer to Figure 1 The cavity wall at the bottom of the oil storage cavity 111 has a protrusion 161 protruding toward the top of the oil storage cavity 111 , and at least one of the first detection electrode 13 and the second detection electrode 14 passes through the protrusion 161 .

[0051] Further, in one embodiment, please refer to Figure 1 The atomizer 1 includes a sealing seat 16, a protrusion 161 is located on the sealing seat 16, the sealing seat 16 is located at the bottom of the oil storage chamber 111 and is sealed with the atomizer shell 11, and the first detection electrode 13 and the second detection electrode 14 both pass through the sealing seat 16. Specifically, in one embodiment, please refer to Figure 1 The sealing seat 16 is inserted into the base 15. After the base 15 is fixed, the sealing seat 16 can be prevented from leaving the atomizer housing 11. The protrusion 161 is located on the sealing seat 16 for easy installation. In one embodiment, the sealing seat 16 is a silicone seat, which is convenient for inserting the detection electrode and sealing with the detection electrode.

[0052] Further, in one embodiment, please refer to Figure 1 , the first detection electrode 13 passes through the protrusion 161. When the atomizer 1 is inhaled, the lowest point of the first contact detection portion 131 is higher than the lowest point of the second contact detection portion 141. In this way, the volume of the protrusion 161 can be reduced, and when the first contact detection portion 131 is disconnected from the second contact detection portion 141, more aerosol generating oil can be retained in the oil storage chamber 111. In one embodiment, only the first detection electrode 13 passes through the protrusion 161.

[0053] Specifically, in one embodiment, please refer to Figure 1 The height of the protrusion 161 is designed according to the minimum set amount of the aerosol generating oil. When the minimum set amount of the aerosol generating oil is large, the design height of the protrusion 161 is increased, and when the minimum set amount of the aerosol generating oil is small, the design height of the protrusion 161 is reduced.

[0054] Further, in one embodiment, please refer to Figure 1, the first detection electrode 13 and the second detection electrode 14 are inserted into the oil storage chamber 111 from the bottom of the oil storage chamber 111. Since the amount of aerosol-generating oil at the bottom of the oil storage chamber 111 needs to be detected, it is easier to design the bottom to be inserted into the oil storage chamber 111. In some other embodiments, in addition to being inserted into the oil storage chamber 111 from the bottom of the oil storage chamber 111, the oil storage chamber 111 can also be inserted from any feasible position such as the top or the middle.

[0055] In some other embodiments, the detection electrode can be inserted into the oil storage cavity 111 from the top thereof without providing the protrusion 161 at the bottom of the oil storage cavity 111 . It is only necessary to control the insertion depth of the detection electrode.

[0056] Further, in one embodiment, please refer to Figure 1 The electronic atomization device 1 includes a detection circuit, and the first detection electrode 13 and the second detection electrode 14 are both connected in the detection circuit, so that the detection circuit can detect the electrical parameters between the first detection electrode 13 and the second detection electrode 14, wherein the electrical parameters include but are not limited to current, resistance, voltage, and on-off state. When in use, after the atomizer 1 is plugged into the detection circuit through a conductive plug, the amount of aerosol generated oil in the oil storage chamber 111 can be detected. In some other embodiments, the detection circuit can also be integrated in the atomizer 1, in which case the atomizer 1 includes the detection circuit.

[0057] In one embodiment, please refer to Figure 1 The electronic atomization device includes an oil replenishing container 3 and a pumping mechanism 4. The oil replenishing container 3 is used to store aerosol generating oil. The pumping mechanism 4 is used to provide power to transport the aerosol generating oil in the oil replenishing container 3 to the oil storage chamber 111.

[0058] The electronic atomization device includes a control system, which is connected to the detection circuit to obtain detection information of the detection circuit. The control system is connected to the pumping mechanism 4 to control the operation of the pumping mechanism 4. The control system controls the operation of the pumping mechanism 4 according to the detection information of the detection circuit.

[0059] In one embodiment, please refer to Figure 1 When the detection circuit detects that the first detection electrode 13 and the second detection electrode 14 are disconnected or the resistance between them increases to more than the set value, the aerosol generating oil in the oil storage chamber 111 needs to be supplemented, and the control system controls the pumping mechanism 4 to start working. When the detection circuit detects that the first detection electrode 13 and the second detection electrode 14 are connected or the resistance between them is less than the set value, the aerosol generating oil in the oil storage chamber 111 does not need to be supplemented, and the control system controls the pumping mechanism 4 not to work.

[0060] Specifically, in one embodiment, when the amount of aerosol generating oil remaining in the atomizer is greater than a set value, both the first detection electrode 13 and the second detection electrode 14 are in contact with the aerosol generating oil, and the aerosol generating oil connects the circuit of the first detection electrode 13 and the second detection electrode 14, and the user can use it normally. When the amount of aerosol generating oil remaining in the atomizer is less than a set value, the aerosol generating oil liquid level is lower than the required height, the first detection electrode 13 does not contact the aerosol generating oil, and the second detection electrode 14 is in a disconnected state. At this time, the control system will recognize the signal and make a judgment and prompt, and release a working instruction to the pumping mechanism.

[0061] In some other embodiments, in addition to controlling the pumping mechanism 4 to work fully automatically, the control system may also work in other modes. For example, the electronic atomization device includes a button and an indicator light. When the aerosol generating oil in the oil storage chamber 111 is insufficient, the indicator light gives a signal. At this time, the user chooses whether to press the button according to the signal of the indicator light. Pressing the button can start the pumping mechanism 4. In some other embodiments, in addition to the indicator light, a buzzer can also be used to generate a sound oil replenishment signal. In some other embodiments, in addition to the pumping mechanism 4, manual refueling can also be used. After the indicator light or buzzer sends a refueling signal, the user is informed of the need to refill the oil storage chamber 111 as needed, and refills the oil by squeezing the oil refilling container 3 or inverting the electronic atomization device.

[0062] In one embodiment, please refer to Figure 1 , the power source 2 is a battery cell, and the battery cell supplies power to the pumping mechanism 4 and the atomizing core 12. In one embodiment, please refer to Figure 1 The control system includes a PCBA assembly 5, and the battery core provides power to the PCBA assembly 5. At least a part of the detection circuit is located on the PCBA assembly 5.

[0063] In one embodiment, please refer to Figure 1 The heating element 122 includes a first working electrode 1221 and a second working electrode 1222 . The first working electrode 1221 and the second working electrode 1222 are both connected to a control system so that the control system can control the operation of the heating element 122 .

[0064] In one embodiment, please refer to Figure 1, the first detection electrode 13 and the second detection electrode 14 are both connected to the control system, so that the control system can know the on-off state of the first detection electrode 13 and the second detection electrode 14. The control system needs to collect the resistance signal between the first detection electrode 13 and the second detection electrode 14 as a basis for judging whether the atomizer 1 has sufficient aerosol generating oil remaining. When it is identified that the remaining amount of aerosol generating oil is sufficient, the user issues a work instruction, the control system outputs electrical energy to the working electrode in time, and the atomizer 1 works normally. When it is identified that the remaining amount of aerosol generating oil is less than the set value, the control system determines that the atomizer 1 needs to add aerosol generating oil, and prompts the user to add aerosol generating oil to the atomizer 1. The control system controls the pumping mechanism 4 to work, and the pumping mechanism 4 pumps the aerosol generating oil in the oil replenishing container 3 to the oil storage chamber 111 of the atomizer 1. After pumping a certain amount of aerosol generating oil, the aerosol generating oil in the oil storage chamber 111 is sufficient, and the control system controls the pumping mechanism 4 to stop working, and the pumping mechanism 4 stops delivering the aerosol generating oil. The signal transmitted by the detection electrode to the control system will be recognized as sufficient remaining aerosol generating oil. At this time, if the user issues a working instruction, the atomizer 1 can work normally.

[0065] In order to facilitate oil replenishment, in one embodiment, please refer to Figure 1 , an oil passage 6 and an air passage 7 are provided between the oil replenishing container 3 and the oil storage chamber 111. The oil passage 6 connects the oil storage chamber 111 and the oil replenishing container 3, so that the aerosol generating oil enters the oil storage chamber 111 from the oil replenishing container 3. The air passage 7 is used to allow the oil storage chamber 111 to exhaust air into the oil replenishing container 3. The air passage 7 connects the oil storage chamber 111 and the oil replenishing container 3. In the process of conveying the aerosol generating oil, the air passage 7 can exhaust air from the oil storage chamber 111 into the oil replenishing container 3, so that the aerosol generating oil quickly enters the oil storage chamber 111. The aerosol generating oil in the oil replenishing container 3 is conveyed to the oil storage chamber 111 through the oil passage 6 by the pumping mechanism 4. In the process of conveying the aerosol generating oil, the gas in the oil storage chamber 111 is discharged into the oil replenishing container 3, so that the aerosol generating oil quickly and smoothly enters the oil storage chamber 111.

[0066] In one embodiment, please refer to Figure 1 The oil storage chamber 111 is located between the atomizer core housing 123 and the atomizer housing 11, and the atomizer core 12 is arranged in the center, so that the oil storage chamber 111 is an annular chamber. In addition to the annular chamber form, the atomizer core 12 and the oil storage chamber 111 can also be arranged side by side, and the oil storage chamber 111 is located beside the atomizer core 12.

[0067] Regarding the form of the pumping mechanism 4, in one embodiment, please refer to Figure 1 The pumping mechanism 4 is an oil pump. Specifically, the oil pump can be a micro oil pump or a peristaltic pump. When the pumping mechanism 4 is a peristaltic pump, the oil channel and the gas channel can be combined into one.

[0068] In one embodiment, please refer to Figure 1 The pumping mechanism 4 is arranged on the oil passage 6 to pump the aerosol-generating oil from the oil replenishing container 3 into the oil storage chamber 111. Specifically, the electronic atomization device includes an oil supply pipe 8, and the channel in the oil supply pipe 8 forms at least a part of the oil passage 6. The pumping mechanism 4 is connected to the oil supply pipe 8. Specifically, the electronic atomization device also includes an air pipe 9, and the channel in the air pipe 9 forms at least a part of the air passage 7.

[0069] Further, in one embodiment, please refer to Figure 1 , the oil path channel 6 includes a first oil path opening 61 and a second oil path opening, the first oil path opening 61 is in communication with the oil storage chamber 111, and the second oil path opening is in communication with the oil replenishing container 3, and the gas path channel 7 includes a first gas path opening 71 and a second gas path opening, the first gas path opening 71 is in communication with the oil storage chamber 111, and the second gas path opening is in communication with the oil replenishing container 3. When the aerosol in the atomizer core 12 is sucked, the first oil path opening 61 is lower than the first gas path opening 71, so that the aerosol-generated oil is not easy to enter the gas path channel 7. In some other embodiments, when the aerosol in the atomizer core 12 is sucked, the first oil path opening 61 is level with the first gas path opening 71. In some other embodiments, when the aerosol in the atomizer core 12 is sucked, the first oil path opening 61 may also be higher than the first gas path opening 71.

[0070] Further, in one embodiment, please refer to Figure 1 When the aerosol in the atomizer core 12 is sucked, the first oil path opening 61 is higher than the oil hole 1231, so that the first oil path opening 61 is not easily blocked by the aerosol generated oil in the oil storage chamber 111. In some other embodiments, when the aerosol in the atomizer core 12 is sucked, the first oil path opening 61 can also be flush with the oil hole 1231, and of course the first oil path opening 61 can also be lower than the oil hole 1231.

[0071] Regarding the structure of the atomizer housing 11, in one embodiment, please refer to Figure 1 The atomizer core 12 is located in the atomizer shell 11, the oil storage cavity 111 is an annular cavity located between the atomizer core 12 and the shell, the atomizer shell 11 includes an outer annular cavity wall spaced opposite to the atomizer core 12, and the first oil path opening 61 and the first gas path opening 71 are both located on the outer annular cavity wall.

[0072] The atomizer housing 11 has an oil circuit joint connected to the oil supply pipe 8 and an air circuit joint connected to the air pipe 9, both of which are located on the outer annular cavity wall. Both the oil circuit joint and the air circuit joint protrude outward, which makes it convenient to connect the oil circuit joint with the oil supply pipe 8, and also convenient to connect the air circuit joint with the air pipe 9.

[0073] Further, in one embodiment, please refer to Figure 1 The oil replenishing container 3 includes an oil replenishing bottle 31, a bottle cap 32, and a bottle cap oil pipe 33 disposed on the bottle cap 32. The bottle cap 32 covers the bottle mouth of the oil replenishing bottle 31, and the oil passage 6 is connected to the bottle cap oil pipe 33. The bottle cap oil pipe 33 extends from the bottle mouth to the bottom of the oil replenishing bottle 31, so that the aerosol generating oil can enter the bottle cap oil pipe 33. Specifically, in one embodiment, the bottle cap oil pipe 33 extends to the bottom of the oil replenishing bottle 31, and the bottle cap oil pipe 33 has a connecting groove 331 connected to the bottom of the oil replenishing bottle 31, or the end face of the bottle cap oil pipe 33 and the oil replenishing bottle 31 have a gap, so that the aerosol generating oil can enter. In one embodiment, the bottle cap 32 and the bottle cap oil pipe 33 are integrally formed.

[0074] Further, in one embodiment, please refer to Figure 1 The bottle cap 32 has a bottle cap air hole 321 , the air path channel 7 is in communication with the bottle cap air hole 321 , and the bottle cap air hole 321 opens toward the oil replenishing bottle 31 and is located at the top of the oil replenishing bottle 31 .

[0075] When the aerosol generating oil needs to be delivered, the aerosol generating oil is sucked out of the oil replenishing bottle 31 from the bottle cap oil pipe 33 extending to the bottom, and at the same time, the air in the oil storage chamber 111 enters the oil replenishing bottle 31 from the air pipe 9 to maintain the air pressure balance of the oil replenishing bottle 31.

[0076] Specifically, in one embodiment, please refer to Figure 1 The bottle cap 32 is buckled on the oil replenishing bottle 31 , and a sealing silica gel is provided between the oil replenishing bottle 31 and the bottle cap 32 , and the sealing silica gel seals the oil replenishing bottle 31 .

[0077] The aerosol generating oil in the present application is a conductive oil. In one embodiment, the aerosol generating oil is a weak conductor, and a detection electrode is designed in the atomizer to detect the remaining aerosol generating oil in the atomizer. When the remaining aerosol generating oil is greater than the system setting amount, the user can use the product normally. When the remaining oil is less than the system setting amount, the detection information is obtained by the control system, and the control system prompts the user to add oil or directly releases instructions to the pumping mechanism. The pumping mechanism receives the instructions and can quantitatively supply oil to the inside of the atomizer to avoid the exhaustion of the aerosol generating oil in the atomizer, thereby avoiding the phenomenon of burnt smell, no smoke, and damage to the atomizer. Refilling oil through the oil filling container can also have a better battery life experience, which not only meets the regulatory requirements of some regions with capacity restrictions on the oil storage chamber, but also meets the user's requirements for long battery life, and there is no need to carry an additional oil storage device when going out. It should be noted that the oil filling container can be removed as needed, and the corresponding channel opening can be blocked with a sealing plug after removal.

[0078] In an embodiment of an atomizer, the atomizer can adopt the atomizer of any embodiment of the above-mentioned electronic atomization device, and the details are not repeated.

[0079] The above specific examples are used to illustrate the present application, which is only used to help understand the present application and is not intended to limit the present application. For technicians in the technical field to which the present application belongs, they can also make some simple deductions, deformations or substitutions based on the ideas of the present application.
