Abstract
Description
Technical Field
[0001] This application relates to the field of electronic atomization device technology, specifically to a power supply component and an electronic atomization device. Background Technology
[0002] Electronic atomizing devices are a common type of electronic product, consisting of an atomizer that heats and atomizes a liquid matrix to form an aerosol, and a power supply component that provides electrical energy.
[0003] To ensure electronic atomizers possess a certain draw resistance, which contributes to a better user experience, related technologies incorporate an air-blocking channel or orifice in the air intake path that connects the atomizer to the atmosphere. This reduces the flow area and thus increases draw resistance. In the assembly process of electronic atomizers, some designs involve the atomizer extending into the power supply component's housing for assembly. However, due to material assembly tolerances and cumulative tolerances, gaps may form between the atomizer and the power supply component's housing. The internal sealing of this space significantly impacts the accurate control of draw resistance. Therefore, it is crucial to design the internal structure of electronic atomizers to avoid compromising the accuracy of draw resistance settings. Utility Model Content

The air-blocking structure connects the ventilation cavity and the air intake channel.
[0010] A first seal is sealingly connected between the outer periphery of the bracket and the inner wall of the housing, the first seal being located on the side of the air intake duct away from the assembly cavity; and
[0011] The second sealing element is sealed to one end of the bracket near the assembly cavity. The second sealing element is used to abut against the end of the atomizer to seal, so that the ventilation cavity is in sealed communication with the atomizer.
[0012] Optionally, the second seal includes:
[0013] The first ring portion is sealed and connected to one end of the bracket near the assembly cavity; and
[0014] The second ring is connected to the side of the first ring facing the assembly cavity and is disposed around the outer periphery of the ventilation cavity. The second ring is used to abut and seal against the end of the atomizer.
[0015] Optionally, along the radial direction of the second seal, at the junction of the first ring portion and the second ring portion, there is a gap between the inner edge of the second ring portion and the inner edge of the first ring portion, and / or, there is a gap between the outer edge of the second ring portion and the outer edge of the first ring portion.

[0022] The second ring portion is disposed on the termination portion.
[0023] Optionally, there is a gap between the outer periphery of the second seal and the inner wall of the housing.
[0024] Optionally, the outer peripheral wall of the bracket is provided with a circumferential groove, which cooperates with the housing to form the air intake.
[0025] Optionally, the outer peripheral wall of the bracket is provided with a sealing groove to accommodate the first sealing element.
[0026] Optionally, the air-blocking structure is an air-blocking hole opened on the bracket, and the housing is provided with an air inlet for the air inlet channel. The flow area of the air-blocking hole is smaller than the flow area of the air inlet.

[0029] The power supply component is any one of the power supply components mentioned above; and
[0030] The atomizer is located in the assembly cavity and abuts against the second seal, and the atomizer is electrically connected to the power supply assembly.
[0031] The power supply assembly provided in this application includes a housing, a battery, a bracket, a first seal, and a second seal. The housing has an open end. The battery is disposed in the housing. The bracket is disposed in the housing and forms an assembly cavity for accommodating an atomizer between itself and the open end. An air intake channel communicating with the external environment is formed between the outer periphery of the bracket and the inner wall of the housing. The bracket is provided with a ventilation cavity communicating with the assembly cavity and an air-blocking structure that provides suction resistance. The air-blocking structure connects the ventilation cavity and the air intake channel. The first seal is sealed between the outer periphery of the bracket and the inner wall of the housing. The first seal is located on the side of the air intake channel away from the assembly cavity. The second seal is sealed at the end of the bracket near the assembly cavity. The second seal is used to abut against the end of the atomizer for sealing, so that the ventilation cavity and the atomizer are in a sealed communication. This design creates a sequentially connected airflow channel consisting of an air inlet, an air-blocking structure, and a ventilation chamber. The arrangement of the first seal ensures that the airflow in the air inlet primarily originates from the air inlet port, guaranteeing basic sealing. The arrangement of the second seal provides sealed assembly conditions for the atomizer. Thus, the atomizer can be easily installed into the assembly chamber along the length of the housing from the open end. Moreover, regardless of whether there is any leakage between the atomizer and the housing after installation, the airflow entering the ventilation chamber passes through the air-blocking structure, and the ventilation chamber and atomizer are sealed and connected, effectively ensuring the accuracy of the draw resistance setting. This solves the problem of how to design the internal structure of existing electronic atomizing devices without affecting the accuracy of the draw resistance setting. Attached Figure Description

[0044] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0045] like Figures 1-4As shown, this application embodiment provides a power supply assembly 100, including a housing 110, a battery, a bracket 120, a first seal 130, and a second seal 140; the housing 110 has an open end; the battery is disposed in the housing 110 and can be configured to be mounted and connected to the bracket 120; the bracket 120 is disposed in the housing 110 and forms an assembly cavity 1101 for accommodating an atomizer 200 between itself and the open end, that is, the battery is located in the space inside the housing 110 away from the assembly cavity 1101; an air intake duct 1201 communicating with the external environment is formed between the outer periphery of the bracket 120 and the inner wall of the housing 110. The bracket 120 is provided with a ventilation chamber 1202 communicating with the assembly cavity 1101 and an air-blocking structure that provides suction resistance. The air-blocking structure connects the air intake 1201 and the ventilation chamber 1202. A first annular seal 130 is sealed between the outer periphery of the bracket 120 and the inner wall of the housing 110. The first seal 130 is located on the side of the air intake 1201 away from the assembly cavity 1101. A second annular seal 140 is sealed at the end of the bracket 120 near the assembly cavity 1101. The second seal 140 is used to abut against the end of the atomizer 200 to seal, so that the ventilation chamber 1202 is in sealed communication with the atomizer 200. That is, the bottom of the ventilation chamber 1202 in the bracket 120 is closed and the top is open, so that the top of the ventilation chamber 1202 can be in sealed communication with the atomizer 200.
[0046] With this configuration, the bracket 120 and the housing 110 form an airflow channel that is sequentially connected to the air inlet 1201, the air-blocking structure, and the ventilation chamber 1202. The arrangement of the first sealing element 130 ensures that the airflow in the air inlet 1201 mainly originates from the air inlet hole 1102 of the air inlet 1201, ensuring basic sealing. The arrangement of the second sealing element 140 provides sealed assembly conditions for the atomizer 200. Thus, the atomizer 200 can be installed into the assembly chamber 1101 from the open end of the housing 110 along the length direction of the housing 110, which is easy to assemble. Moreover, regardless of whether there is any air leakage between the atomizer 200 and the housing 110 after it is installed in the housing 110, since the airflow entering the ventilation chamber 1202 is ensured to pass through the air-blocking structure and the ventilation chamber 1202 and the atomizer 200 are sealed and connected, the accuracy of the draw resistance setting can be effectively guaranteed. This solves the problem of how to design the internal structure of electronic atomizing devices in the prior art so as not to affect the accuracy of the draw resistance setting. Furthermore, the fact that the draw resistance of the e-cigarette is not affected by air leakage also helps to ensure that the sensitivity of the e-cigarette is not affected. It also makes the assembly of the e-cigarette easier.
[0047] For example, Figure 2 The leak point between the atomizer 200 and the housing 110 of the power supply component 100 is shown at point A. Figure 2 and Figure 3 The arrows in the diagram indicate the flow path of the airflow.
[0048] The first seal 130 and the second seal 140 can be made of silicone or rubber, etc.
[0049] In some alternative embodiments, the second seal 140 has an irregular design that differs from conventional sealing rings. The second seal 140 includes an integrally connected first ring portion 141 and a second ring portion 142. The first ring portion 141 is sealed to one end of the bracket 120 near the assembly cavity 1101. The second ring portion 142 is connected to the side of the first ring portion 141 facing the assembly cavity 1101 and is disposed around the outer periphery of the ventilation cavity 1202. The second ring portion 142 is used to abut and seal against the end of the atomizer 200.
[0050] In some alternative embodiments, along the radial direction of the second seal 140, at the junction of the first ring portion 141 and the second ring portion 142, there is a gap between the inner edge of the second ring portion 142 and the inner edge of the first ring portion 141; or, there is a gap between the outer edge of the second ring portion 142 and the outer edge of the first ring portion 141; or, there is a gap between the inner edge of the second ring portion 142 and the inner edge of the first ring portion 141, and a gap between the outer edge of the second ring portion 142 and the outer edge of the first ring portion 141. Preferably, the gap is between the inner edge of the second ring portion 142 and the inner edge of the first ring portion 141, and a gap is also present between the outer edge of the second ring portion 142 and the outer edge of the first ring portion 141.
[0051] With this configuration, the first ring portion 141 serves as the main body of the second seal 140, and the thickness of the second ring portion 142 is less than that of the first ring portion 141. The second ring portion 142 is thinner and easier to deform, achieving a tight contact with the end of the atomizer 200, which helps to ensure good assembly sealing. In addition, the second ring portion 142 is located inside the outer edge of the first ring portion 141, which also makes it easy to adapt to the atomizer 200 with rounded edges, ensuring reliable contact between the second ring portion 142 and the atomizer 200, and preventing loose connections.
[0052] In some alternative embodiments, the second ring 142 is gradually widening along the direction from the end of the first ring 141 to the end of the second ring 142. This configuration, where the second ring 142 is inclined relative to the first ring 141, provides a downward deformation space on the lower outer side of the second ring 142, which helps to enhance the sealing reliability between the second seal 140 and the atomizer 200.
[0053] In some alternative embodiments, the thickness of the second ring 142 gradually decreases along the direction from the end of the first ring 141 to the end of the second ring 142. This configuration makes the second ring 142 more elastic and easier to deform, making it easier to achieve close contact with the atomizer 200, which helps to enhance the sealing reliability between the second seal 140 and the atomizer 200.
[0054] In some optional embodiments, the first ring portion 141 includes an integrally connected outer portion 1411, an inner portion 1412, and an end portion 1413; the outer portion 1411 is sealed to the outer peripheral wall of the bracket 120; the inner portion 1412 is sealed to the inner peripheral wall of the bracket 120; the end portion 1413 is connected between the outer portion 1411 and the inner portion 1412, and the end portion 1413 is sealed to the end face of the bracket 120 facing the assembly cavity 1101, that is, the first ring portion 141 is matched and connected to the end of the bracket 120 facing the assembly cavity 1101. The second ring portion 142 is located on the end portion 1413.
[0055] With this configuration, the sealing connection between the first ring 141 and the bracket 120 facing the assembly cavity 1101 is highly reliable, and the second seal 140 and the bracket 120 have a stable connection relationship. Thus, before the atomizer 200 is installed into the housing 110, the position of the second seal 140 in the housing 110 is determined, and it will not shake or fall off. This facilitates reliable docking between the atomizer 200 and the second seal 140, thereby achieving a sealed contact.
[0056] In some alternative embodiments, there is a gap between the outer periphery of the second seal 140 and the inner wall of the housing 110. That is, there is a gap between the outer portion 1411 of the first ring 141 and the inner wall of the housing 110.
[0057] With this configuration, the second seal 140 only needs to ensure that it can abut and seal with the atomizer 200, without having a sealing relationship with the inner wall of the housing 110. In this way, during the process of installing the bracket 120 into the housing 110, the second seal 140 will not be deformed, misaligned or fall off due to interference with the inner wall of the housing 110, and the assembly operation is smooth.
[0058] Regarding the formation of the air intake 1201, the airflow space can be provided by the bracket 120 or the housing 110. In some optional embodiments, the outer peripheral wall of the bracket 120 is provided with a surrounding groove, which cooperates with the housing 110 to form the air intake 1201. Considering that the bracket 120 is generally a plastic part, while the housing 110 is usually a metal shell to give the product a textured feel, the air intake 1201, with its certain structural complexity, is designed on the bracket 120, making it easy to obtain through injection molding, which helps control production costs.
[0059] In some optional embodiments, the outer peripheral wall of the bracket 120 is provided with a sealing groove to accommodate the first sealing member 130, and the edge of the first sealing member 130 extends beyond the sealing groove. This ensures that the first sealing member 130 is mounted on the bracket 120 and that the first sealing member 130 will not be misaligned during the process of the bracket 120 being installed into the housing 110.
[0060] Of course, in addition to the above methods, it is also feasible to provide multiple limiting protrusions distributed on both sides of the first seal 130 on the outer peripheral wall of the bracket 120 to limit the connection of the first seal 130 to the bracket 120.
[0061] In some optional embodiments, the air interception structure is an air interception hole 1203 opened on the bracket 120, and the housing 110 is provided with an air inlet hole 1102 of the air inlet channel 1201. The flow area of the air interception hole 1203 is smaller than the flow area of the air inlet hole 1102.
[0062] With this configuration, the air inlet 1102 is located on the housing 110. Since it only serves as an air intake, it does not require high precision. It is sufficient that the flow area of the cut-off hole 1203 is smaller than the flow area of the air inlet 1102. Therefore, the shape of the air inlet 1102 is no longer limited to a circular hole and can have a variety of shapes, which can realize ID matching design.
[0063] Of course, in addition to the above methods, it is also feasible to design the air interception structure as an air interception channel with a gradually changing flow area on the support 120.
[0064] In some alternative embodiments, the bracket 120 is an injection molded part, and the air vent 1203 is an injection molding hole, that is, the air vent 1203 is integrally formed during the injection molding of the bracket 120.
[0065] With this configuration, the bracket 120 is generally designed as an injection-molded part, and the vent 1203 is more precise on the bracket 120 because it is directly formed by the mold. This process allows for more precise tolerance control, achieving a tolerance within ±0.02mm. In related technologies, the vent 1203 is designed on the housing 110. The metal housing 110 undergoes subtractive processing, resulting in a machining tolerance beyond ±0.05mm. Furthermore, it is affected by subsequent processes, such as the anodizing time and secondary anodizing, leading to poorer tolerance control for the vent 1203. Therefore, the technical solution provided in this application offers more stable suction resistance.
[0066] It should be noted that the air shut-off hole 1203 on the bracket 120 can be designed in various shapes, including but not limited to circular holes, oval holes, waist-shaped holes, etc.
[0067] Based on the aforementioned power supply component 100, this application embodiment also provides an electronic atomizing device, which includes the power supply component 100 and an atomizer 200. The power supply component 100 is the one described above, and the atomizer 200 is located in the assembly cavity 1101 and abuts against the second seal 140, and the atomizer 200 is electrically connected to the power supply component 100. Since this electronic atomizing device has the aforementioned power supply component 100, the beneficial effects brought by the power supply component 100 to the electronic atomizing device are described above and will not be repeated here.
