Description

Technical Field

[0001] This utility model relates to the field of electronic cigarette technology, and in particular to an atomizing component and an electronic cigarette. Background Technology

[0002] Electronic cigarettes typically consist of a power source and an atomizing component. The atomizing component is the core component of an electronic cigarette, and it usually includes a housing and an atomizing core housed within the housing. The housing has a reservoir for storing a solution, and the atomizing core is used to atomize the solution to produce an aerosol.

[0003] However, e-cigarettes in this technology still have many problems that need improvement or optimization. One common issue is leakage from the atomizing component. For example, when an e-cigarette is left unused for a period of time before use, solution may leak from the atomizing component. This makes it easy for users to inhale large droplets; or, insufficient atomization results in a noticeable aerosol particle sensation and a very poor aerosol taste. Furthermore, under conditions of high altitude and low pressure, high temperature and high humidity during storage and use, the solution inside the atomizing component can be squeezed out, causing leakage and leading to solution waste and leakage.

The lower seal and the housing cooperate to form the second channel, and the lower connecting hole communicates with the second channel.

[0016] In some embodiments, the atomizing core includes:

[0017] The inner sleeve is inserted into the outer sleeve, and the liquid storage cotton is sandwiched between the inner sleeve and the outer sleeve, and the air passage passes through the inner sleeve;

[0018] A liquid-guiding cotton is inserted into the inner sleeve, and the inner sleeve has a guide hole through which the liquid-guiding cotton and the liquid-storing cotton are connected.

[0019] A heating element is disposed in the inner sleeve, and the liquid-guiding cotton is wrapped around the heating element;

[0020] The inner sleeve has an upper through hole in its upper region and a lower through hole in its lower region, and the liquid storage cotton covers the upper through hole and the lower through hole.

[0021] In some embodiments, the receiving space is a downward-facing groove with a through hole at the bottom of the groove. The upper sealing member covers the housing and is located on the outer surface of the housing opposite to the groove. The upper end of the outer sleeve passes through the through hole and is inserted into the upper sealing member. The lower end of the atomizing core is inserted into the lower sealing member to form a sealed liquid storage cavity.

[0022] In some implementations, the first channel includes:

[0032] The beneficial effects of this utility model are:

[0033] The atomizing component of this utility model is designed with a first channel and a second channel. The first channel and the second channel respectively connect the liquid storage chamber to the liquid storage cotton of the atomizing core. The first channel is located at the upper end of the liquid storage chamber along the first direction, and the second channel is located at the lower end of the liquid storage chamber along the first direction.

[0034] When in use, the atomizing component is upright. The air pressure inside the reservoir decreases, and external air pressure replenishes the reservoir through the first channel. In high-temperature or low-pressure environments, when the air pressure inside the reservoir exceeds the external air pressure, pressure is released through the first channel to prevent the solution from being forced out of the reservoir through the second channel, thus preventing leakage. In this state, the first channel primarily releases pressure, while the second channel primarily guides the solution, thereby preventing leakage caused by the solution being forced out of the reservoir through the second channel.

[0035] Furthermore, when the atomizing component is in an inverted position and the air pressure inside the liquid storage chamber is greater than the external atmospheric pressure, the second channel is mainly used for pressure relief (i.e., the functions of the first and second channels are interchanged). In this state, the air pressure inside the liquid storage chamber is relieved through the second channel, causing the air pressure inside the liquid storage chamber to tend to balance, preventing the solution from being discharged from the first channel due to pressure relief and thus avoiding leakage, thereby improving the user experience.

[0058] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0059] refer to Figures 1-4 Some embodiments of this application provide an atomizing assembly for use in electronic cigarettes. The atomizing assembly has an atomizing core 400 and a liquid storage chamber 500. The atomizing core 400 includes a liquid storage cotton 420 and an airway 480 extending along a first direction X. The atomizing assembly also includes a first channel 600 and a second channel 700. One end of the first channel 600 is connected to one end of the liquid storage chamber 500 along the first direction X, and the other end of the first channel 600 is connected to the liquid storage cotton 420, so as to communicate with the airway 480 through the liquid storage cotton 420. One end of the second channel 700 is connected to the other end of the liquid storage chamber 500 along the first direction X, and the other end of the second channel 700 is connected to the liquid storage cotton 420, so as to communicate with the airway 480 through the liquid storage cotton 420.

[0060] In some embodiments of this application, the atomizing component is designed with both a first channel 600 and a second channel 700. The first channel 600 and the second channel 700 respectively connect the liquid storage chamber 500 to the liquid storage cotton 420 of the atomizing core 400. The first channel 600 is located at the upper end of the liquid storage chamber 500 along the first direction X, and the second channel 700 is located at the lower end of the liquid storage chamber along the first direction X. When the user uses it, the atomizing component is in an upright state. The solution in the liquid storage chamber 500 is consumed, causing the air pressure to decrease. Then, the external air pressure is replenished into the liquid storage chamber 500 through the first channel 600. When the temperature is high, the gas in the liquid storage chamber 500 absorbs heat and expands, causing the air pressure in the liquid storage chamber 500 to increase. Therefore, the pressure can be released through the first channel 600 to prevent the solution in the liquid storage chamber 500 from being squeezed out of the second channel 700 by the increased air pressure, thus preventing oil leakage. In a low-pressure environment, the air pressure inside the liquid storage chamber 500 is greater than the external air pressure. Therefore, the pressure can be released through the first channel 600 to prevent the solution inside the liquid storage chamber 500 from being squeezed out of the second channel 700 by the air pressure that is greater than the external air pressure, thus preventing oil leakage. At this time, the first channel 600 is mainly used for pressure relief, and the second channel 700 is mainly used for liquid guiding. The functions of the first channel 600 and the second channel 700 can be interchanged in different placement states. Since both the first channel 600 and the second channel 700 are connected to the liquid storage cotton 420 of the atomizing core 400, some solution may be discharged during the pressure relief process of the first channel 600. The liquid storage cotton 420 can absorb this solution, thereby reducing the leakage phenomenon. When the atomizing component is not in use, after the air pressure in the liquid storage chamber 500 is relieved by the first channel 600, the liquid supply from the second channel 700 to the liquid storage cotton 420 is reduced, which helps to reduce leakage. When the atomizing component is in use, the solution in the liquid storage chamber 500 is consumed, which reduces the air pressure in the liquid storage chamber 500. Therefore, outside air enters the liquid storage chamber 500 through the first channel 600 to replenish the air pressure. At this time, the air pressure in the liquid storage chamber 500 tends to be balanced, thereby making the liquid supply from the second channel 700 to the liquid storage cotton 420 stable. Furthermore, in other situations, when the atomizing component is inverted and the air pressure in the liquid storage chamber 500 increases, the second channel 700 can release pressure. Therefore, in this state, the solution in the liquid storage chamber 500 is reduced by being guided through the first channel 600 to the liquid storage cotton 420 of the atomizing core 400, thus preventing leakage. This application's design primarily utilizes the interchangeable functions of the first channel 600 and the second channel 700, and allows for pressure release based on different placement states of the atomizing component and when the air pressure in the liquid storage chamber 500 exceeds the external air pressure, thereby reducing leakage and improving the user experience.

[0061] It should be noted that the atomizing core 400 itself contains a liquid storage cotton 420. The atomizing core 400 itself is a structural component that communicates with the external atmosphere through the liquid storage cotton 420 to facilitate ventilation and aerosol export and inhalation. This part is existing technology and will not be elaborated on in detail. Therefore, the atomizing core 400 can be regarded as a communicating vessel connected to the liquid storage chamber 500, which can be called the second chamber. The liquid storage chamber 500 is called the first chamber. During atomization, the liquid level in the second chamber drops, and the first chamber replenishes the second chamber with solution. Afterward, the interior of the first chamber is under negative pressure. The first channel 600 communicates with the atmosphere through the atomizing core 400. Air enters the first chamber through the first channel 600, and then causes the liquid in the first chamber to enter the second chamber through the second channel 700. When the liquid absorbed in the second chamber rises to near or above the first channel 600, it helps to block the communication between the first channel 600 and the atmosphere, so that the first chamber and the second chamber reach a steady state. When the air pressure inside the first chamber is greater than the external air pressure, the pressure is released to the outside atmosphere through the first channel 600 or the second channel 700. The first channel 600 is located above the liquid level in the first chamber, and the flowing medium is air. The second channel 700 is located below the liquid level in the first chamber, and the flowing medium is liquid. According to the Hagen-Poiseuille law, the air flow rate is greater than the liquid flow rate per unit time. Therefore, during the pressure relief process, the first channel 600 discharges more gas than the second channel 700 discharges more liquid, thus preventing liquid leakage.

[0062] Regarding the specific structure of the atomizing component, in some implementation methods, refer to... Figures 1-4 The atomizing assembly includes a housing 100, an upper seal 200, and a lower seal 300. The housing 100 has an accommodating space; the upper seal 200 is positioned above the accommodating space along a first direction X, and the lower seal 300 is positioned below the accommodating space along the first direction X. The atomizing core 400 also includes an outer sleeve 410, through which an air passage 480 passes. The outer sleeve 410 is positioned within the accommodating space and, together with the upper seal 200, the lower seal 300, and the housing 100, forms a sealed liquid storage chamber 500. The upper portion of the outer sleeve 410... The outer sleeve 410 has an upper connecting hole 411 and a lower connecting hole 412 in the lower part of the outer sleeve 410. The liquid storage cotton 420 is inserted into the outer sleeve 410 and covers the upper connecting hole 411 and the lower connecting hole 412. The upper sealing member 200 and the housing 100 cooperate to form a first channel 600, and the upper connecting hole 411 communicates with the first channel 600. The lower sealing member 300 and the housing 100 cooperate to form a second channel 700, and the lower connecting hole 412 communicates with the second channel 700.

[0063] In some implementations, reference Figures 1-7 , Figure 11 and Figure 17In the first direction X, one end of the liquid storage chamber 500 is the upper end, and the other end is the lower end; wherein, the end of the first channel 600 that connects to the liquid storage cotton 420 is located above the liquid storage chamber 500. The liquid storage chamber 500 and the liquid storage cotton 420 form a communicating vessel structure through the first channel 600. Since the end of the first channel 600 that connects to the liquid storage cotton 420 is located above the liquid storage chamber 500, when the atomizing component is in the upright state, the end of the first channel 600 that connects to the liquid storage cotton 420 is at a higher position than the end of the first channel 600 that connects to the liquid storage chamber 500, thereby facilitating pressure relief and ventilation to maintain pressure balance within the liquid storage chamber 500.

[0064] refer to Figures 1-7 , Figure 11 and Figure 17 In some embodiments, in the first direction X, one end of the liquid storage chamber 500 is the upper end, and the other end is the lower end; the end of the second channel 700 that communicates with the liquid storage cotton 420 is located below the liquid storage chamber 500. Similarly, the liquid storage chamber 500 and the liquid storage cotton 420 form a communicating vessel structure through the second channel 700. The end of the second channel 700 that communicates with the liquid storage cotton 420 is located below the liquid storage chamber 500. Therefore, when the atomizing component is in an upright state, the end of the second channel 700 that communicates with the liquid storage cotton 420 is at a lower position relative to the end of the second channel 700 that communicates with the liquid storage chamber 500. This facilitates the flow of the solution in the liquid storage chamber 500 to the liquid storage cotton 420 by gravity, ensuring smooth solution conduction. At the same time, the liquid storage cotton 420 then guides the solution to the atomizing position of the atomizing core 400 in the opposite direction of gravity, further preventing the risk of leakage. When the atomizing component is in the inverted position, the end of the liquid storage chamber 500 that is connected to the liquid storage cotton 420 of the atomizing core 400 relative to the second channel 700 is in a lower position, which reduces the resistance brought by the solution in the liquid storage chamber 500, thereby facilitating pressure relief and ventilation.

[0065] In some implementations, reference Figures 1-7 , Figure 11 and Figure 17The first distance is the flow distance along the flow direction of the first channel 600, from the end of the first channel 600 connected to the liquid storage chamber 500 to the end of the first channel 600 connected to the atomizing core 400. The second distance is the flow distance along the flow direction of the second channel 700, from the end of the second channel 700 connected to the liquid storage chamber 500 to the end of the second channel 700 connected to the atomizing core 400. The first distance is less than or equal to the second distance. In summary, the lengths of the first and second distances affect the ease of flow guidance or pressure relief. A longer first distance means greater difficulty for the solution in the liquid storage chamber 500 to flow out of the atomizing core 400 through the first channel 600 in the inverted state, due to the longer flow path. Similarly, a longer second distance means greater difficulty for the solution in the liquid storage chamber 500 to flow out of the atomizing core 400 through the second channel 700. In the upright position, because the first distance is smaller than the second distance, it is more difficult for gas to flow through the second channel 700, which is conducive to ventilating and depressurizing the liquid storage chamber 500 through the first channel 600.

[0066] When placed upright, the solution flows from the storage chamber 500, through the second channel 700, and then to the atomizing core 400. During this process, the pressure driving the solution flow is relatively high. Therefore, when the air pressure inside the storage chamber 500 is greater than the external air pressure, the downward pressure is relatively high. That is, the pressure required to move the solution in the storage chamber 500 to the second channel 700 is relatively high. As a result, the pressure relief from the first channel 600 is faster than that from the second channel 700. Therefore, after the pressure relief from the first channel 600, the pressure inside and outside the storage chamber 500 tends to be balanced, which can avoid the risk of leakage caused by pressure relief from the second channel 700. Specifically, because the path of the second channel 700 is relatively long, the force generated between the liquid and the second channel 700 is relatively large. Therefore, the solution in the liquid storage chamber 500 needs to be under relatively high pressure to push the solution in the second channel 700 to flow to the atomizing core 400. Therefore, when the gas pressure in the liquid storage chamber 500 is relatively high, the gas preferentially chooses the first channel 600 for flow. When the liquid is upright, there is less solution in the first channel 600, so less force is needed to push the solution in the first channel 600 open and allow the gas to be discharged from the liquid storage chamber 500. This avoids the risk of leakage caused by pressure relief from the second channel 700.

[0067] Furthermore, regarding the specific structure of the atomizer core 400, please refer to [reference needed]. Figures 1-4In some embodiments, the atomizing core 400 further includes an inner sleeve 430, a liquid-guiding cotton 440, and a heating element 450. The inner sleeve 430 is inserted into the outer sleeve 410, and the liquid-retaining cotton 420 is sandwiched between the inner sleeve 430 and the outer sleeve 410, with an air passage 480 penetrating the inner sleeve 430; the liquid-guiding cotton 440 is inserted into the inner sleeve 430, and the inner sleeve 430 has a guide hole 433, through which the liquid-guiding cotton 440 and the liquid-retaining cotton 420 are connected; the heating element 450 is disposed in the inner sleeve 430, and the liquid-guiding cotton 440 wraps around the heating element 450; wherein, the upper region of the inner sleeve 430 has an upper guide hole 431, and the lower region of the inner sleeve 430 has a lower guide hole 432, and the liquid-retaining cotton 420 covers the upper guide hole 431 and the lower guide hole 432. Because the inner sleeve 430 has a lower through hole 432 and an upper through hole 431, and the outer sleeve 410 has a lower connecting hole 412 and an upper connecting hole 411, and the liquid storage cotton 420 is sandwiched between the inner sleeve 430 and the outer sleeve 410, the first channel 600 and the second channel 700 are respectively connected to the liquid storage cotton 420, forming a micro-channel for flow guidance in the liquid storage cotton 420, thus achieving pressure relief or liquid guidance. (Explanatory) Figure 2 The dashed lines in the diagram represent the circulation path.

[0068] Furthermore, in some implementations, see [link to implementation details]. Figure 2 and Figure 5 The atomizing core 400 also includes a first sealing ring 460 and a second sealing ring 470. The first sealing ring 460 is clamped at the upper end between the outer sleeve 410 and the inner sleeve 430, and the second sealing ring 470 is clamped at the lower end between the outer sleeve 410 and the inner sleeve 430. Thus, the outer sleeve 410, the inner sleeve 430, the first sealing ring 460, and the second sealing ring 470 define a relatively closed space for accommodating the liquid storage cotton 420, which helps to reduce leakage and allows the liquid to flow as much as possible into the space defined by the outer sleeve 410, the inner sleeve 430, the first sealing ring 460, and the second sealing ring 470, that is, onto the liquid storage cotton 420.

[0069] Further, refer to Figures 1-4 as well as Figures 10-13 In some embodiments, no inlet or outlet hole is provided in the middle of the outer sleeve 410, which helps to prevent excessive solution from flowing into the atomizing core 400 and causing leakage. In addition, the lower seal 300 is sealed and plugged into the outer sleeve 410, so that the solution in the liquid storage chamber 500 must be transferred to the atomizing core 400 through the second channel 700.

[0070] Of course, in other implementations, refer to Figures 14-17The outer tube 410 can also be provided with a liquid inlet hole 413, which directly connects the liquid storage chamber 500 and the liquid storage cotton 420 to achieve liquid replenishment. Specifically, the diameter and number of liquid inlet holes 413 can be flexibly designed according to the needs. On the one hand, it can ensure good liquid replenishment capacity, and on the other hand, by reducing the number of liquid inlet holes 413 and reducing the diameter of the liquid inlet holes 413, it can also suppress or avoid the problem of easy leakage caused by excessive liquid replenishment capacity.

[0071] For the specific structure of the containing space and the formation method of the liquid storage chamber 500, please refer to [reference needed]. Figures 2-7 In some embodiments, the accommodating space is a downward-facing groove with a through hole 110 at the bottom of the groove. The upper seal 200 covers the housing 100 and is located on the outer surface of the housing 100 opposite to the groove. The upper end of the outer sleeve 410 passes through the through hole 110 and is inserted into the upper seal 200. The lower end of the atomizing core 400 is inserted into the lower seal 300 to form a sealed liquid storage chamber 500.

[0072] In some implementations, reference Figures 2-7 The first channel 600 includes a first conductive section 610 and a second conductive section 620. The first conductive section 610 is formed in the housing 100 and penetrates the bottom of the tank, communicating with the liquid storage chamber 500. A flow guiding groove 621 is formed on the outer surface of the housing 100 opposite to the groove. The upper sealing member 200 covers the flow guiding groove 621 and cooperates with the flow guiding groove 621 to define the second conductive section 620. One end of the first conductive section 610 communicates with the liquid storage chamber 500, and the other end of the first conductive section 610 communicates with one end of the second conductive section 620. The other end of the second conductive section 620 communicates with the liquid storage cotton 420. The flow guiding groove 621 is formed on the outer surface of the tank bottom for easy processing. Explanatoryly, the outer surface of the tank bottom refers to the side of the tank bottom facing away from the receiving space.

[0073] In some implementations, reference Figures 5-7The second conductive section 620 includes multiple series-connected bends in the tubing. These multiple bends increase the difficulty of flow channeling; the more bends and the longer the length, the greater the difficulty of flow channeling. The number of bends can be selected according to requirements to control the ease of flow channeling. Alternatively, when the atomizing component is inverted and the air pressure inside the liquid storage chamber 500 is greater than the external air pressure, the liquid in the liquid storage chamber 500 passes through the bends in the second conductive section 620. Because the second conductive section 620 includes multiple series-connected bends, and the air pressure inside the liquid storage chamber 500 needs to be greater than the pressure required to pass through the second conductive section 620 for the liquid to be discharged and depressurized, the second channel 700, which functions as a depressurizer, will preferentially release pressure from the liquid storage chamber 500, preventing leakage caused by depressurization from the second conductive section 620.

[0074] refer to Figure 2 , Figure 5 and Figures 8-11 In some embodiments, the lower seal 300 has an insertion through hole 310, and the lower end of the atomizing core 400 is inserted into the insertion through hole 310. The second channel 700 includes a third conducting section 710 and a fourth conducting section 720. The third conducting section 710 is a through hole that penetrates the wall of the insertion through hole 310. The side wall of the lower seal 300 has a drainage groove 721, and the housing 100 covers the drainage groove 721 and defines the fourth conducting section 720 in conjunction with the drainage groove 721. One end of the fourth conducting section 720 is connected to the liquid storage chamber 500, and the other end of the fourth conducting section 720 is connected to one end of the third conducting section 710. The other end of the third conducting section 710 is connected to the liquid storage cotton 420. The drainage groove 721 on the side wall of the lower seal 300 is easy to process and manufacture, and it is used to define the fourth conducting section 720 in conjunction with the inner wall of the housing 100.

[0075] In some implementations, reference Figure 5 and Figures 8-11The fourth conduction section 720 is a continuously curved, serpentine tube. Similarly, the more bends and the longer the fourth conduction section 720, the more difficult the flow guidance becomes. The number of bends can be selected according to requirements to control the ease of flow guidance. Alternatively, it can be understood that when the atomizing component is upright and the air pressure inside the liquid storage chamber 500 is greater than the external air pressure, the liquid in the liquid storage chamber 500 flows through the serpentine tube of the fourth conduction section 720. Because the fourth conduction section 720 is a continuously curved, serpentine tube, the air pressure inside the liquid storage chamber 500 needs to be greater than the pressure required to release pressure through the second channel 700 for the liquid to be discharged through the second conduction section 620. Simultaneously, since the first channel 600 functions as a pressure release point, the air pressure in the liquid storage chamber 500 is preferentially released through the first channel 600 to avoid leakage caused by pressure release through the second channel 700.

[0076] In addition, refer to Figure 1 , Figure 2 and Figure 5 The atomizing assembly may further include an upper absorbent cotton 800, a lower absorbent cotton 900, a nozzle 1000, and a bottom cover 1100. The nozzle 1000 is located above the housing 100 and is fixedly connected to it. The upper absorbent cotton 800 is sandwiched between the nozzle 1000 and the upper seal 200. The lower absorbent cotton 900 is sandwiched between the lower seal 300 and the bottom cover 1100. The bottom cover 1100 is fixedly connected to the housing 100 and is located below it. The upper absorbent cotton 800, lower absorbent cotton 900, nozzle 1000, and bottom cover 1100 have openings communicating with the atomizing core 400 for atomization ventilation. Existing structures can be used for this purpose, and will not be elaborated further. (Reference) Figure 1 and Figure 18 Some embodiments of this application also provide an electronic cigarette that includes the atomizing component of any of the above embodiments.

[0077] Finally, it should be noted that the technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments have been described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
