Description

Technical Field

[0001] This application belongs to the technical field of atomizing devices, specifically relating to a sealing element, an atomizer, and an atomizing device. Background Technology

[0002] Currently, during use, the atomizer allows for air exchange between the outside air and the internal atomization chamber.

[0003] In prior art, the aforementioned ventilation action is usually achieved by plastic grooving or solely by oil-conducting cotton wrapped around the heating element.

[0004] However, with the continuous development of atomizers, the ventilation structure may adopt new materials. How to achieve ventilation and avoid leakage of the atomizing matrix in the ventilation structure using new materials is a problem that needs to be solved in the current development of atomizers. Utility Model Content

[0005] The purpose of this application is to provide a seal, atomizer, and atomizing device that can solve at least some of the above-mentioned problems.

[0006] To solve the above-mentioned technical problems, this application is implemented as follows:

[0007] In a first aspect, embodiments of this application provide a sealing element applied to an atomizer. The atomizer has a liquid storage chamber, and the sealing element seals the liquid storage chamber. The sealing element includes a nested portion, and the nested portion has a connecting hole along a first direction. The nested portion has a recessed first ventilation groove, which is disposed on the inner wall of the connecting hole. The first ventilation groove includes an air inlet section, a middle section, and an air outlet section. The air inlet section, the middle section, and the air outlet section are sequentially connected, and the air inlet section and the air outlet section are parallel. The end of the air inlet section away from the middle section is located at the bottom of the nested portion, and the end of the air outlet section away from the middle section is located at the top of the nested portion.

[0008] In this embodiment, the sealing element can be made of an elastic material, such as silicone. The sealing element is used to seal the atomizing matrix in the liquid storage chamber. The sealing element may include a nested portion, which is configured to connect and cooperate with the atomizing component in the atomizer. The nested portion has a through-hole, which is used to limit the connection of the atomizing component. The nested portion provides a mounting carrier for the through-hole and the first ventilation groove, allowing for the orderly integration of various functional structures and ensuring the stability and integrity of the overall sealing element structure.

[0009] The first ventilation groove is recessed within the nested section and located on the inner wall of the connecting hole. This positional feature allows it to directly connect the inside of the liquid storage chamber with the external environment, providing a spatial basis for gas exchange and leak prevention. Furthermore, the inlet section, intermediate section, and outlet section are sequentially connected, with the intermediate section and outlet section parallel, forming a Z-shaped channel structure. When a negative pressure forms inside the liquid storage chamber, external air attempts to enter under the pressure difference. Although the Z-shaped channel has bends, the air has good flowability and diffusion, allowing it to easily pass through the inlet section, intermediate section, and outlet section into the liquid storage chamber. This promptly balances the air pressure inside and outside the liquid storage chamber, preventing problems such as poor atomization and insufficient supply of the atomizing matrix caused by negative pressure, thus ensuring stable operation of the atomizer.

[0010] For the atomizing matrix within the storage chamber, the "Z"-shaped first venting groove effectively acts as a barrier. As a liquid, the atomizing matrix possesses a certain viscosity and surface tension. When the atomizing matrix attempts to enter the first venting groove, the "Z"-shaped bends impede its flow. At the junctions between the outlet and intermediate sections, and between the intermediate and inlet sections, the surface tension of the atomizing matrix makes it difficult for it to cross the corners and continue flowing, while the increased viscosity further enhances its flow resistance. This significantly reduces the likelihood of the atomizing matrix entering the venting groove and leaking to the outside, minimizing matrix waste and ensuring the cleanliness and hygiene of the atomizer.

[0011] In the embodiments of this application, the various structural features of the sealing element cooperate with each other to achieve the basic function of sealing the liquid storage cavity. At the same time, through the special "Z"-shaped structure of the first air exchange groove, the contradiction between negative pressure gas replenishment in the liquid storage cavity and prevention of leakage of the atomizing matrix is ​​cleverly resolved, which has the beneficial effect of improving the performance and reliability of the atomizer.

[0012] Optionally, in this embodiment of the application, a first angle is formed between the air intake section and the middle section, and a second angle is formed between the middle section and the air outlet section, wherein at least one of the first angle and the second angle is α, and 80°≤α≤100°.

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0030] The seal, atomizer, and atomizing device provided in this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0031] See Figures 1 to 5 This application provides a sealing member 10 for use in an atomizer. The atomizer has a liquid storage chamber 50, and the sealing member 10 seals the liquid storage chamber 50. The sealing member 10 includes a nested portion 11, and the nested portion 11 has a connecting hole 111 along a first direction Y. The nested portion 11 has a first ventilation groove 112 recessed therein, and the first ventilation groove 112 is disposed on the inner wall of the connecting hole 111. The first ventilation groove 112 includes an air inlet section 1121, a middle section 1122, and an air outlet section 1123. The air inlet section 1121, the middle section 1122, and the air outlet section 1123 are connected in sequence, and the air inlet section 1121 and the air outlet section 1123 are parallel. The end of the air inlet section 1121 away from the middle section 1122 is located at the bottom of the nested portion 11, and the end of the air outlet section 1123 away from the middle section 1122 is located at the top of the nested portion 11.

[0032] In this embodiment, the sealing element 10 can be made of an elastic material, such as silicone. The sealing element 10 is used to seal the atomizing matrix in the liquid storage chamber 50. The sealing element 10 may include a nesting portion 11, which is configured to cooperate and connect with the atomizing component 40 in the atomizer. The nesting portion 11 has a connecting hole 111 that passes through it, which is used to limit the connection of the atomizing component 40. The nesting portion 11 provides a mounting carrier for the connecting hole 111 and the first ventilation groove 112, allowing the functional structures to be integrated in an orderly manner, thus ensuring the stability and integrity of the overall structure of the sealing element 10.

[0033] The first ventilation groove 112 is recessed in the nested part 11 and located on the inner wall of the connecting hole 111. This positional feature allows it to directly communicate between the inside and outside environment of the liquid storage chamber 50, providing a spatial basis for gas exchange and leak prevention. Furthermore, the inlet section 1121, the intermediate section 1122, and the outlet section 1123 are sequentially connected, with the intermediate section 1122 and the outlet section 1123 being parallel, forming a Z-shaped channel structure. When a negative pressure forms inside the liquid storage chamber 50, external air will attempt to enter the liquid storage chamber 50 under the influence of the pressure difference. For air, although the Z-shaped channel has bends, the gas has good flowability and diffusion, allowing it to easily pass through the inlet section 1121, the intermediate section 1122, and the outlet section 1123 into the liquid storage chamber 50 in sequence. This timely balances the air pressure inside and outside the liquid storage chamber 50, avoiding problems such as poor atomization and insufficient supply of atomizing matrix caused by negative pressure, ensuring stable operation of the atomizer.

[0034] For the atomizing matrix within the liquid storage chamber 50, the "Z"-shaped first ventilation groove 112 effectively acts as a barrier. As a liquid, the atomizing matrix possesses a certain viscosity and surface tension. When the atomizing matrix attempts to enter the first ventilation groove 112, the "Z"-shaped bend obstructs its flow. At the connection points between the outlet section 1123 and the intermediate section 1122, and between the intermediate section 1122 and the inlet section 1121, the surface tension of the atomizing matrix makes it difficult for it to cross the corners and continue flowing, and the increased viscosity further enhances its flow resistance. This significantly reduces the possibility of the atomizing matrix entering the ventilation groove and leaking to the outside, thus reducing waste of the atomizing matrix and ensuring the cleanliness and hygiene of the atomizer.

[0035] In this embodiment, the structural features of the sealing element 10 cooperate with each other to achieve the basic function of sealing the liquid storage chamber 50. At the same time, the special "Z"-shaped structure of the first air exchange groove 112 cleverly solves the contradiction between negative pressure air replenishment in the liquid storage chamber 50 and prevention of leakage of the atomizing matrix, which has the beneficial effect of improving the performance and reliability of the atomizer.

[0036] It should be noted that the groove depth and groove width of the air outlet section 1123 and the intermediate section 1122 can be the same. For example, the groove width can be 0.3-0.4mm and the groove depth can be 0.2-0.3mm.

[0037] Optionally, in this embodiment of the application, a first included angle is formed between the air intake section 1121 and the middle section 1122, and a second included angle is formed between the middle section 1122 and the air outlet section 1123, wherein at least one of the first included angle and the second included angle is α, and 80°≤α≤100°.

[0038] In this embodiment, at least one of the first included angle and the second included angle is α, wherein 80°≤α≤100°. α within the above range allows for relatively smooth airflow in the first ventilation slot 112. The following describes in detail the setting method of the first included angle and the second included angle using α as 90° (right angle) as an example.

[0039] In one scenario, the first included angle is a right angle, and the second included angle is a non-right angle (acute or obtuse). A 90° first included angle is formed between the intake section 1121 and the intermediate section 1122, while a non-90° second included angle is formed between the intermediate section 1122 and the exhaust section 1123. The overall structure still forms a "Z"-shaped channel, but the degree of curvature at the second corner differs from that of a right angle. The 90° first included angle ensures that when air enters the intermediate section 1122 from the intake section 1121, although there is a slight turn, the angle is moderate. The airflow will not experience excessive resistance due to an overly sharp corner, nor will it weaken the "Z"-shaped characteristic of the channel due to an overly blunt angle. Air can smoothly pass through the right-angle bend of the intake section 1121 into the intermediate section 1122, then through the second included angle into the exhaust section 1123, and finally flow into the liquid storage chamber 50, effectively balancing the negative pressure. For the atomizing matrix, the right angle of the first included angle forms the first strong physical barrier. When the atomizing matrix attempts to flow from the liquid storage chamber 50 through the air outlet section 1123 and the intermediate section 1122 to the air inlet section 1121, its surface tension and viscosity at the first 90° corner will make it difficult to turn and pass smoothly. Even if it can barely cross the first corner, the existence of the second included angle will further hinder its flow, greatly reducing the probability of the atomizing matrix entering the air exchange tank.

[0040] In another scenario, the second included angle is a right angle, while the first included angle is not a right angle (acute or obtuse). A non-90° first included angle is formed between the inlet section 1121 and the intermediate section 1122, while a 90° second included angle is formed between the intermediate section 1122 and the outlet section 1123. The second corner of the "Z"-shaped channel is a standard right angle, while the degree of curvature of the first corner varies. When air enters the intermediate section 1122 from the inlet section 1121 via the first included angle, the 90° turning angle at the right angle of the second included angle guides the airflow to smoothly change direction and enter the outlet section 1123, reducing airflow turbulence and ensuring that air can easily pass through the entire channel into the liquid storage chamber 50. However, during the flow of the atomizing matrix, the right angle of the second included angle becomes a critical obstruction point. The atomizing matrix must pass through the right-angle bend of the second included angle before it can enter the middle section 1122 from the outlet section 1123 and then flow to the inlet section 1121. The obstruction caused by the right angle makes it difficult for the atomizing matrix to cross. In addition, the presence of the first included angle further increases the complexity and resistance of the atomizing matrix flow path, making it difficult for the atomizing matrix to enter the air exchange slot and effectively preventing leakage.

[0041] In another scenario, both the first and second included angles are right angles. The air inlet section 1121 and the intermediate section 1122, as well as the intermediate section 1122 and the outlet section 1123, form 90° angles. The entire first ventilation channel 112 exhibits a standard "Z"-shaped right-angle bend structure, with both corners having the same 90° turning angle. This double right-angle structure maximizes the characteristics of the "Z"-shaped channel. For air, the two 90° corners form an orderly turning path. During airflow, each turn maintains good fluidity, preventing excessive energy loss due to improper corner design. This allows air to easily pass through the air inlet section 1121, the intermediate section 1122, and the outlet section 1123 into the liquid storage chamber 50, quickly balancing the internal and external air pressure of the liquid storage chamber 50. For the atomizing matrix, the double right angles form two robust barriers. When the atomizing matrix flows, it is first obstructed at the right angle between the air outlet section 1123 and the middle section 1122. Its surface tension makes it difficult to form a continuous flow surface at the right angle, and its viscosity increases the difficulty of crossing the corner. Even if a small amount of atomizing matrix breaks through the first right angle, it will be blocked again at the right angle between the air inlet section 1121 and the middle section 1122. The double blocking effect significantly reduces the possibility of the atomizing matrix entering the air exchange slot, minimizes the risk of atomizing matrix leakage, and ensures smooth air replenishment when the liquid storage chamber is under 50 negative pressure.

[0042] In the embodiments of this application, whether it is a single right angle or a double right angle structure design, the presence of a 90° right angle can ensure that air can easily enter the liquid storage chamber 50 through the "Z" shaped channel while effectively blocking the atomizing matrix. Among them, the double right angle structure performs better in terms of balancing air pressure and preventing leakage.

[0043] Optionally, in this embodiment of the application, the air intake section 1121 has a first end 11211 and a second end 11212, the first end 11211 is connected to the middle section 1122, and the second end 11212 extends away from the middle section 1122; along the first direction Y from the first end 11211 to the second end 11212, the circumferential dimension of the air intake section 1121 gradually decreases along the inner wall of the connecting hole 111.

[0044] In this embodiment, along the first direction Y (from the first end 11211 to the second end 11212, i.e., from near the middle section 1122 towards the outside away from the liquid storage chamber 50), the circumferential dimension of the air intake section 1121 gradually decreases along the inner wall of the connecting hole 111, forming a narrowing structure of "wide → narrow". This feature causes the cross-sectional area of ​​the air intake section 1121 to gradually decrease from the first end 11211 connected to the middle section 1122 to the second end 11212 away from the liquid storage chamber 50. According to the fluid mechanics relationship "flow rate = velocity × cross-sectional area", under the same pressure difference, the gradual change in cross-sectional area will directly affect the airflow speed and the intake volume per unit time, thereby achieving precise control of the intake rate. The second end 11212 of the air intake section 1121 extends away from the middle section 1122 and away from the liquid storage chamber 50, and the extension direction is consistent with the first direction Y of the connecting hole 111, forming an independent air intake channel with a fixed orientation. The length of this channel and the gradually changing slope of its size work together to further refine the adjustment range of the intake rate. The longer extension length combined with the gradual narrowing of the size allows for a more uniform change in the intake rate, avoiding fluctuations in the intake rate caused by a channel that is too short or narrows too abruptly.

[0045] In practical applications, when a negative pressure is formed inside the liquid storage chamber 50, external air enters from the second end 11212 (narrow opening) of the air inlet section 1121 and flows towards the first end 11211 (wide opening). Due to the gradual transition from wide to narrow in the air inlet section 1121, the airflow velocity is relatively fast in the initial stage (at the narrow opening), but the airflow volume per unit time is limited by the narrow opening; as it flows towards the wide opening, the flow velocity gradually slows down, and the airflow volume steadily increases, eventually entering the middle section 1122 at a stable rate through the first end 11211. This "fast at first, slow later, and controllable total volume" air intake process avoids a sudden surge of air, allowing the internal air pressure of the liquid storage chamber 50 to rise steadily, preventing atomization matrix splashing or unstable atomization caused by sudden changes in airflow rate.

[0046] Furthermore, the negative pressure level of the liquid storage chamber 50 changes dynamically with the atomization process (e.g., the negative pressure becomes more pronounced when the atomization intensity increases). When the negative pressure is low, the pressure difference driving force is weak, and the air flow velocity at the narrow opening of the air inlet section 1121 is slow. At this time, the "wide→narrow" structure can limit the air intake volume and avoid unnecessary excessive air intake. When the negative pressure is high, the driving force is enhanced, and the air can overcome the resistance of the narrow opening more quickly. It also gains more flow space during the flow to the wide opening, and the air intake rate increases accordingly, quickly replenishing the air required by the liquid storage chamber 50. This characteristic of "automatic adaptation to negative pressure" ensures that the air intake rate always matches the actual needs of the liquid storage chamber 50.

[0047] Furthermore, the stability and controllability of the air intake rate directly affects the atomization quality. If the air intake is too fast, too much air will dilute the concentration of the atomizing matrix, resulting in weaker atomized smoke and a poorer taste; if the air intake is too slow, the negative pressure in the reservoir chamber cannot be balanced in time, causing insufficient supply of the atomizing matrix, resulting in reduced smoke volume or even atomization interruption. In this application, the "wide-to-narrow" gradient structure of the air intake section 1121, through precise control of the air intake rate, keeps the mixing ratio of air and atomizing matrix always within an optimal range, ensuring continuous and stable atomization, uniform smoke volume, and improved user experience.

[0048] Because the air intake rate is effectively controlled, the airflow into the intermediate section 1122 and the outlet section 1123 is more stable, avoiding the impact of high-speed airflow on the atomizing matrix near the inner wall of the connecting hole 111. Combined with the extension direction of the air intake section 1121 away from the liquid storage chamber 50, the risk of airflow disturbance causing the atomizing matrix to enter the channel is further reduced, enhancing the leak-proof effect while controlling the air intake. The combination of the "wide → narrow" size gradient feature of the air intake section 1121 and its extension direction in this application constructs an efficient air intake rate control mechanism at the structural level. This mechanism can adapt to the dynamic negative pressure requirements of the liquid storage chamber 50 while ensuring the stability of the atomization effect, making it an important design for the functionality and reliability of the sealing element 10.

[0049] Optionally, in this embodiment of the application, the nested part 11 is provided with a second ventilation groove 113, which is recessed at the bottom of the nested part 11 and is connected to the air inlet section 1121.

[0050] In this embodiment, the second ventilation groove 113 is recessed at the bottom of the nested portion 11. This position allows it to collect external air from the bottom of the nested portion 11 and the area around the connecting hole 111, effectively adding an "air collection area" to the air intake section 1121. When the liquid storage chamber 50 forms a negative pressure, air converges through the second ventilation groove 113 and flows into the air intake section 1121, significantly expanding the air collection range. This provides more sufficient air reserve when the negative pressure is high. Combined with the "wide to narrow" gradual structure of the air intake section 1121, the control of the air intake rate is more redundant, ensuring that the negative pressure in the liquid storage chamber 50 can be quickly balanced.

[0051] Furthermore, after the second ventilation groove 113 is connected to the air intake section 1121, the air entering the second ventilation groove 113 will be evenly distributed into the air intake section 1121 along its recessed channel. Because the path of the second ventilation groove 113 is relatively gentle (recessed at the bottom), the air flows through it with less disturbance, allowing it to enter the air intake section 1121 in a more stable state, reducing fluctuations in the intake rate caused by air turbulence. This works in conjunction with the "wide→narrow" gradual structure of the air intake section 1121; the second ventilation groove 113 first "pre-stabilizes" the airflow, and the air intake section 1121 then "regulates" it, making the final airflow rate entering the liquid storage chamber 50 more uniform, further ensuring the stability of the atomization process.

[0052] During atomizer use, the bottom of the nested section 11 may develop local gaps due to assembly errors or slight deformation. The presence of the second air exchange groove 113 guides the air from these gaps to the air intake section 1121, preventing air from entering through unintended paths (such as direct leakage from the gaps) and ensuring the controllability of the air intake process. This design enhances the tolerance of the seal 10 to assembly errors and improves the compatibility and reliability of the overall structure.

[0053] In this embodiment, the second ventilation groove 113 expands the air intake source, optimizes airflow stability, assists in leak prevention, and improves structural compatibility. It works in synergy with the "wide to narrow" gradient structure of the air intake section 1121 and the first ventilation groove 112 to further improve the air intake control system of the seal 10. This results in more efficient air pressure balance in the liquid storage chamber 50, more stable atomization process, and enhanced leak prevention performance.

[0054] It should be noted that the width of the second ventilation slot 113 can be 0.2-0.3mm and the depth can be 0.2-0.3mm. Specifically, the dimensions of the second ventilation slot are a width of 0.3mm and a depth of 0.26mm.

[0055] Optionally, in this embodiment, the second ventilation groove 113 extends along the second direction X of the connecting hole 111.

[0056] In this embodiment, the second ventilation groove 113, extending radially along the connecting hole 111, can expand the air collection range at the bottom of the nested portion 11 along the radial direction of the connecting hole 111. Compared to a non-radial extending structure, the radial extension allows it to cover a larger area around the connecting hole 111, enabling more efficient collection of external air from different locations around the connecting hole 111. When a negative pressure is formed in the liquid storage chamber 50, air from more directions can quickly converge through the radially extending second ventilation groove 113 and then enter the liquid storage chamber 50 through the connected air inlet section 1121, further enhancing the air intake and storage capacity. Especially when the negative pressure is large, it can replenish air more quickly and avoid air intake delay.

[0057] Furthermore, the radially extending path allows air within the second ventilation slot 113 to flow uniformly along the radius of the connecting hole 111 before converging into the intake section 1121. This radial uniformity reduces local congestion of air flowing within the slot, making the airflow into the intake section 1121 more stable and symmetrical, and reducing intake rate fluctuations caused by uneven airflow distribution. Simultaneously, the radial extension, combined with the "wide→narrow" gradient structure of the intake section 1121, allows air to form a more orderly flow direction before entering the intake section 1121, improving the accuracy of airflow control in the intake section 1121 and ensuring the stability of the pressure balance in the liquid storage chamber 50.

[0058] Furthermore, the second direction X of the connecting hole 111 is spatially perpendicular or intersecting with the extension direction (first direction Y) of the intake section 1121. The second air exchange groove 113 extends radially and connects with the intake section 1121, forming a radial collection and axial delivery airflow path conversion. This allows air to efficiently transition from a wide radial collection area to a precise axial delivery channel, resulting in a more rational structural connection. This synergistic relationship reduces energy loss during airflow turning, improves overall intake efficiency, and makes the positional relationship between the second air exchange groove 113, the connecting hole 111, and the intake section 1121 more compact, fully utilizing the space at the bottom of the nested part 11 and optimizing the overall structural layout of the seal 10.

[0059] In summary, the feature of the second air exchange groove 113 extending radially along the connecting hole 111 further optimizes the air intake collection capacity, airflow uniformity, and synergy with other structures. While improving air intake efficiency and stability, it also enhances the leak-proof performance, making the overall function of the seal 10 more complete.

[0060] Optionally, in this embodiment of the application, the nested part 11 is provided with a third ventilation groove 114, which is recessed on the upper end surface of the nested part 11 facing the liquid storage cavity 50, and the third ventilation groove 114 is connected to the air inlet section 1121.

[0061] In this embodiment, when a negative pressure is formed inside the liquid storage chamber 50, external air enters the liquid storage chamber 50 through the second ventilation groove 113, the first ventilation groove 112 and the third ventilation groove 114 to replenish the liquid storage chamber 50 with air, quickly balance the negative pressure of the liquid storage chamber 50 and ensure that the atomization process is not interrupted.

[0062] In practical applications, when the internal pressure of the liquid storage chamber 50 fluctuates due to factors such as liquid consumption (liquid level drop leading to expansion of the gas phase space) and temperature changes (evaporation of the atomizing matrix or thermal expansion and contraction of the gas), the third ventilation slot 114 can connect with the air inlet section 1121 to export the redundant gas in the gas phase space of the liquid storage chamber 50 to the air inlet section 1121 (or supplement the gas to balance the pressure through the air inlet section 1121), thus avoiding negative pressure (causing liquid backflow) or positive pressure (causing liquid overflow) in the liquid storage chamber 50, ensuring that the liquid storage chamber 50 is always in a stable pressure state, and guaranteeing the continuity and safety of liquid transportation and storage.

[0063] Since the third ventilation tank 114 only acts on the gas phase space of the liquid storage chamber 50, the gas flow it guides will not directly impact or agitate the liquid, thus avoiding splashing, eddies or surface fluctuations caused by gas disturbance. It is especially suitable for scenarios with high requirements for liquid stability (such as precision chemical analysis, pharmaceutical preparation storage, and micro-liquid metering), ensuring that the physical properties (such as concentration and purity) and delivery accuracy of the liquid are not affected.

[0064] Furthermore, the third ventilation slot 114 is directly opened in the nested part 11, eliminating the need for additional independent ventilation pipes or valves, reducing the number of parts and lowering the assembly complexity; at the same time, the recessed slot structure facilitates cleaning and maintenance, avoiding gas leakage or impurity accumulation caused by gaps or interfaces of additional parts, thus improving the overall reliability and service life of the device.

[0065] In this embodiment, the third ventilation slot 114, through its structural design of "recessed upper surface + only connected to the gas phase space + directional flow with the air inlet section 1121", not only achieves communication between the liquid storage chamber 50 and the external (air inlet section 1121) gas, but also fundamentally eliminates the risk of gas intrusion into the liquid. Its core value lies in the dual functions of precise gas phase pressure balance and liquid protection, and it is especially suitable for equipment with strict requirements for liquid purity and delivery stability (such as medical instruments, analytical testing devices, precision fluid control systems, etc.), and has outstanding practicality and innovation.

[0066] Optionally, in this embodiment, the third ventilation groove 114 is an arc-shaped groove.

[0067] In this embodiment, the smooth curve structure of the arc-shaped groove can significantly reduce the eddies and resistance of gas during the flow process compared with straight grooves or broken grooves: when the gas flows naturally along the arc surface, the streamline is more continuous, which can avoid airflow collision or stagnation caused by corners and right angles, and ensure that the gas in the gas phase space of the liquid storage chamber 50 is quickly and stably discharged to the inlet section 1121 through the groove, thereby improving the response speed of pressure balance (especially suitable for scenarios where the pressure fluctuation of the liquid storage chamber 50 is more frequent).

[0068] Furthermore, if the upper end face of the nested part 11 facing the liquid storage cavity 50 itself is arc-shaped, circular or has an irregular contour (such as the liquid storage cavity 50 being cylindrical, spherical, etc.), the arc-shaped groove can be designed to fit the curved surface form of this end face, avoiding space waste or weakening of structural strength caused by the need to "cut" the end face structure by a straight groove; at the same time, the arc-shaped trajectory can extend the gas flow path within the limited end face space (compared with a straight groove of the same length, the arc can achieve a longer groove body within a smaller projected area), improving the contact stability between the gas and the groove wall and reducing local air pressure mutations.

[0069] Furthermore, compared with the problem that stress concentration is likely to occur at the corners of a straight groove, the uniform curvature of the arc-shaped groove can make the material of the nested part 11受力 more dispersed, avoiding cracking at the edge of the groove caused by the periodic pressure impact of gas flow during long-term use. The arc-shaped design can significantly extend its service life and reduce maintenance costs.

[0070] In the embodiment of the present application, the design of the arc-shaped groove has dimensions such as hydrodynamic optimization (reducing resistance), improved space adaptability (compactness), and structural strength guarantee (dispersing stress), further enhancing the stability, adaptability, and durability of the device.

[0071] Optionally, in the embodiment of the present application, the dimension of the first air exchange groove 112 along the second direction X of the connection hole 111 is A, and the dimension of the second air exchange groove 113 along the first direction Y is B, where A ≥ B.

[0072] In the embodiment of the present application, when air enters the intake section 1121 from the second air exchange groove 113, the groove depth shows a non-increasing transition: if B < A, a stepped deepening of "shallow groove → deep groove" is formed; if B = A, a smooth transition of "equal-depth continuation" is formed. The above gradient cooperates with the channel direction: the second air exchange groove 113 extends along the bottom surface of the nested part 11, and the first air exchange groove 112 extends along the inner wall of the connection hole 111. The depth A ≥ B ensures that when the air flow enters the deep groove from the shallow groove, the channel capacity does not contract, avoiding a sudden increase in air flow resistance caused by a sudden decrease in depth.

[0073] Furthermore, the second air exchange groove 113 is the entrance for air to enter. If B > A (i.e., the groove depth of the entrance is greater than that of the main channel), when air enters the narrow and shallow main channel from the wide and deep entrance, turbulence will be formed due to the sudden reduction of the channel capacity, increasing the air supplement resistance (especially in the negative pressure state, where air needs to rush in quickly to balance the pressure in the liquid storage cavity 50). When A ≥ B, the capacity of the main channel (the first air exchange groove 112) ≥ the capacity of the entrance (the second air exchange groove 113), and the air flow can "smoothly expand" or "continue with equal capacity" from the entrance to the main channel, reducing turbulence loss, increasing the air supplement speed, and avoiding the sense of air sucking when the user sucks.

[0074] In this embodiment, the dimensional design of A≥B is not a simple numerical relationship, but rather a precise match between the physical properties of air and atomizing matrix through a gradient configuration of shallow inlet and deep main channel. Specifically, it ensures that the air channel capacity does not shrink, reduces flow resistance, and enhances the air replenishment efficiency under negative pressure; it utilizes shallow groove constraints and depth difference resistance to reduce the possibility of the atomizing matrix entering the main channel, and, combined with the tortuousness of the Z-shaped path, forms a "double leak-proof" system; and it considers the strength of the bottom and the inner wall of the connecting hole 111 to avoid sealing failure or structural damage caused by unreasonable groove depth design.

[0075] Secondly, embodiments of this application provide an atomizer, including a housing 20, a base 30, an atomizing component 40, and a sealing element 10 as described above; the housing 20 and the base 30 are connected to form a liquid storage chamber 50, the sealing element 10 is disposed between the housing 20 and the base 30 and connected to the housing 20 and the base 30 respectively, one end of the atomizing component 40 is inserted into the connecting hole 111 and snapped into the nesting part 11, and the other end of the atomizing component 40 is connected to the mouthpiece of the housing 20; wherein, when the air pressure in the liquid storage chamber 50 is lower than the external air pressure, gas enters the liquid storage chamber 50 through the second ventilation groove 113, the first ventilation groove 112 and the third ventilation groove 114 to balance the air pressure in the liquid storage chamber 50 with the external air pressure.

[0076] In this embodiment, the sealing element 10 as described above is included, as well as all the structural features and beneficial effects of the sealing element 10, which will not be repeated here. The housing 20 and the base 30 are arranged to form a liquid storage cavity 50, which is used to provide a space for the atomizing matrix. The sealing element 10 is disposed between the housing 20 and the base 30. On the one hand, it is used to seal the liquid storage cavity 50 to prevent the atomizing matrix from leaking out.

Furthermore, by providing a first ventilation groove 112 on the inner wall of the connecting hole 111, the air pressure of the liquid storage cavity 50 and the outside world is connected, which has the beneficial effects of regulating the air pressure in the liquid storage cavity 50, realizing ventilation of the atomizer, and improving the user experience.
