Description

Technical Field

[0001] This application relates to the field of electronic atomization technology, and in particular to a support member and an electronic atomization device. Background Technology

[0002] Electronic atomizing devices generally adopt a bottom air intake design, and the aerosol forming product is fixed by a ring-shaped support. This support abuts against the end of the aerosol forming product. The support adopts a central airflow intake method, which makes it impossible for the airflow to enter the aerosol forming product evenly. The specific problems are as follows.

[0003] Central airflow concentration: The airflow passes through the central area of ​​the aerosol-formed product, forming a high-speed airflow channel in the central area of ​​the aerosol-formed product, while the peripheral airflow is almost stagnant.

[0004] Aerosol-formed articles have poor radial permeability: airflow tends to flow along the central axial direction of the aerosol-formed article, but it is difficult to diffuse laterally to the peripheral area.

[0005] Low aerosol extraction efficiency: Although the central airflow can remove most of the atomized aerosols in the central area, the aerosols surrounding the product, lacking airflow, gradually condense and accumulate on the inner wall of the heating chamber, eventually liquefying and adsorbing within the chamber. This condensate not only reduces the amount of smoke but also affects the dielectric constant of the chamber, leading to decreased high-frequency heating performance. Furthermore, the condensate corrodes the heating elements, shortening the equipment's lifespan and potentially causing a burnt odor. Utility Model Content

[0006] To solve at least one of the above-mentioned technical problems, this application provides a support member and an electronic atomizing device, and the technical solution adopted is as follows.

[0007] The support provided in this application includes a hollow body forming an inner cavity with an arcuate surface. The inner cavity of the hollow body is divided into a first chamber and a second chamber by a partition, and the first chamber and the second chamber are spaced apart along a first direction parallel to the axial direction of the hollow body. The partition has a first air intake channel connecting the first chamber and the second chamber, and the side wall of the hollow body has a second air intake channel. The second air intake channel forms a channel opening on the inner side wall of the hollow body. The path of the second air intake channel forming the channel opening through the side wall of the first chamber does not intersect the central axis of the hollow body in the length direction.

[0008] In some embodiments of this application, the second air intake channel has channel openings located on both sides of the partition on the inner wall of the hollow body.

[0009] In some embodiments of this application, at least two second air intake channels are provided, each second air intake channel is distributed circumferentially at intervals along the sidewall of the hollow body, and the channel openings formed by each second air intake channel on the sidewall of the first chamber or the second chamber are distributed circumferentially at intervals.

[0010] In some embodiments of this application, the second air intake channel is formed as an annular channel in the sidewall of the hollow body.

[0011] In some embodiments of this application, the second air intake channel penetrates the sidewall of the first chamber or the second chamber and forms the channel opening tangentially along the inner sidewall of the hollow body.

[0012] In some embodiments of this application, at least two protruding structures are provided on one end of the hollow body for abutting the aerosol forming article. Each of the protruding structures is distributed circumferentially on the end face of the hollow body, and a recessed area is formed between two adjacent protruding structures on the end face of the hollow body. The recessed area forms a first notch on both the inner and outer sidewalls of the hollow body.

[0013] In some embodiments of this application, the protruding structure is formed with one end of the protrusion as the distal end, and the protruding structure is shaped such that the protrusion is larger at the near end and smaller at the far end.

[0014] In some embodiments of this application, the sidewalls of the protruding structure are formed as inclined surfaces at least on the outer side of the hollow body.

[0015] In some embodiments of this application, the protrusion structure is formed as a conical boss, a trapezoidal boss, or a stepped boss.

[0016] In some embodiments of this application, the protruding structure has an abutting surface for abutting the aerosol-forming article, and the total area of ​​the abutting surface of each of the protruding structures accounts for no more than 50% of the area of ​​the end face of the hollow body.

[0017] In some embodiments of this application, the first chamber is located near the end of the protruding structure on the hollow body, the total airflow of the first air intake channel is A, and the total airflow of each of the second air intake channels at the channel opening of the first chamber is B, satisfying: A≤B.

[0018] In some embodiments of this application, the partition is provided with at least two through holes serving as the first air intake channel.

[0019] In some embodiments of this application, the second air intake channel forms a second notch on the outer side wall of the hollow body; and / or, the second air intake channel forms a third notch on the end face of the hollow body away from the aerosol forming article.

[0020] The support provided in this application includes a hollow body, which forms an inner cavity with an arc surface. The side wall of the hollow body has a second air intake channel. The second air intake channel forms a channel opening on the inner side wall of the hollow body. The path of the second air intake channel through the inner side wall of the hollow body to form the channel opening does not intersect with the central axis of the hollow body in the length direction.

[0021] The electronic atomizing device provided in this application includes a heating element and a support member as described above. The heating element has a heating chamber for accommodating at least a portion of the aerosol-forming article. The support member is located at the bottom of the heating chamber, and the first chamber is closer to the aerosol-forming article in the heating chamber than the second chamber. The first chamber communicates with the heating chamber. A third air inlet channel is provided at the bottom of the electronic atomizing device, and the third air inlet channel extends to the second chamber.

[0022] The electronic atomizing device provided in this application includes a heating element and a support member as described above. The heating element has a heating chamber for accommodating at least a portion of the aerosol-forming article. The support member is located at the bottom of the heating chamber, and the first chamber is closer to the aerosol-forming article in the heating chamber than the second chamber. The first chamber communicates with the heating chamber. A fourth air intake channel is provided at the bottom of the electronic atomizing device or along the side wall in a first direction, and the fourth air intake channel extends to the second air intake channel.

[0023] This application has wide applications in the field of electronic atomization technology, and the electronic atomization device therein can improve the uniformity of airflow. The embodiments of this application have at least the following beneficial effects.

[0024] The support component located at the bottom of the electronic atomizing device has a second air intake channel on the side wall of the hollow body. The second air intake channel forms a channel opening on the inner side wall of the hollow body. The airflow in the channel opening enters the inner cavity of the hollow body in a direction that deviates from the radial direction of the hollow body, thereby forming a swirling flow in the hollow body. This ensures that the airflow is fully and evenly distributed in the inner cavity of the hollow body, thereby ensuring that the airflow can not only enter the central area of ​​the aerosol-forming product, but also the peripheral area, thus improving the uniformity of airflow distribution in the aerosol-forming product.

[0025] Furthermore, the hollow body of the support is also designed with a partition, which divides the hollow body into a first chamber and a second chamber that are connected. On the one hand, the airflow entering the first chamber from the second air intake channel can form a swirling flow, improving the uniformity of airflow; on the other hand, the airflow from the second chamber passes through the partition and enters the first chamber to increase the flow velocity of the central airflow and improve the uniformity of airflow distribution.

[0026] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

[0041] This application relates to an electronic atomizing device, which includes a support 1000 and a heating element 2000. The heating element 2000 has a heating chamber 2100 for accommodating at least a portion of the aerosol forming article. The support 1000 is located at the bottom of the heating chamber 2100.

[0042] The heating chamber 2100 has an inlet end, through which the aerosol forming article is loaded into the heating chamber 2100, and the support member 1000 is disposed at the other end of the heating chamber 2100 away from the inlet end.

[0043] Furthermore, the heating chamber 2100 is configured as a cylindrical chamber, the aerosol forming article is inserted into the heating chamber 2100, and the heating element 2000 can heat the aerosol forming article and form atomized aerosol.

[0044] It is understandable that electronic atomizing devices also include a power supply and a controller, with the controller being electrically connected to the power supply.

[0045] Other components and operations of the electronic atomizing device are described elsewhere in the relevant art for those skilled in the art; the structure of the support 1000 will be described below.

[0046] This application relates to a support member 1000 for use in an electronic atomizing device. The support member 1000 includes a hollow body 1100, which forms an inner cavity with an arcuate surface. Taking a direction parallel to the axial direction of the hollow body 1100 as a first direction, the axial directions of both the inner cavity of the hollow body 1100 and the heating chamber 2100 are arranged along the first direction. An aerosol forming article is at least partially inserted into the heating chamber 2100 along the first direction, and the end of the hollow body 1100 facing the aerosol forming article serves to support the end of the aerosol forming article.

[0047] Specifically, the hollow body 1100 forms a ring-shaped support structure, and the inner cavity of the hollow body 1100 is cylindrical.

[0048] The inner cavity of the hollow body 1100 is divided into a first chamber 1301 and a second chamber 1302 by a partition 1200. The partition 1200 is arranged perpendicular to a first direction in the inner cavity of the hollow body 1100, and the first chamber 1301 and the second chamber 1302 are spaced apart along the first direction. Further, the first chamber 1301 is closer to the aerosol-formed article in the heating chamber 2100 than the second chamber 1302. The second chamber 1302 communicates with the first chamber 1301, and the first chamber 1301 communicates with the heating chamber 2100.

[0049] The partition 1200 has a first air intake channel 1201 connecting the first chamber 1301 and the second chamber 1302, and the first air intake channel 1201 extends through the partition 1200 along a first direction. The side wall of the hollow body 1100 has a second air intake channel 1101, and the second air intake channel 1101 has a channel opening 1102 formed on the inner side wall of the hollow body 1100.

[0050] Furthermore, the second air intake channel 1101 has channel openings 1102 formed on the inner wall of the hollow body 1100, located on both sides of the partition 1200. Specifically, the channel opening 1102 on one side of the partition 1200 is located on the side wall of the first chamber 1301, and the channel opening 1102 on the other side is located on the side wall of the second chamber 1302, so that the second air intake channel 1101 communicates with the first chamber 1301 and the second chamber 1302 respectively.

[0051] The path of the second air intake channel 1101 forming the channel opening 1102 at least in the side wall penetrating the first chamber 1301 does not intersect with the central axis of the hollow body 1100 in the length direction, and the extension path of the second air intake channel 1101 forming the channel opening 1102 is offset from the central axis of the hollow body 1100.

[0052] In this case, when the airflow enters the first chamber 1301 from the second air intake channel 1101 through the channel opening 1102, the airflow direction does not point to the central axis of the first chamber 1301. Instead, the airflow can form a swirling flow in the first chamber 1301 so that the airflow is evenly distributed in the first chamber 1301. This helps the airflow to enter the heating chamber 2100 evenly, optimizes the airflow distribution, improves the aerosol transmission efficiency, and thus improves the atomization amount of the product.

[0053] On the other hand, when the second air intake channel 1101 penetrates to form the channel opening 1102 on the side wall of the hollow body, the channel opening 1102 has a side wall extending along the penetration path. The side wall of the channel opening 1102 guides the airflow into the first chamber 1301, which helps to form a vortex.

[0054] It should be noted that, regarding the second air intake channel 1101 forming the channel opening 1102 through the side wall of the first chamber 1301, there are two situations where the path does not intersect the central axis of the hollow body 1100 along its length. In some examples, the path of the second air intake channel 1101 forming the channel opening 1102 through the side wall of the first chamber 1301 does not intersect the central axis of the hollow body 1100, and the path of the second air intake channel 1101 forming the channel opening 1102 through the side wall of the first chamber 1301 is not along the radial direction of the first chamber 1301. In other examples, the paths of the second air intake channel 1101 through the side wall of the first chamber 1301 to form the channel opening 1102 and through the side wall of the second chamber 1302 to form the channel opening 1102 do not intersect the central axis of the hollow body 1100, and the path of the second air intake channel 1101 through the inner side wall of the hollow body 1100 to form the channel opening 1102 is not along the radial direction of the inner cavity of the hollow body 1100.

[0055] Combined with appendix Figure 3As can be understood from the EE cross-sectional view, the airflow direction from the second air intake channel 1101 into the first chamber 1301 does not point to the center of the first chamber 1301.

[0056] To create a swirling flow in the first chamber 1301, the second air intake channel 1101 should be designed to penetrate the side wall of the first chamber 1301, forming a channel opening 1102. The path of this channel opening 1102 should be as far away from the central axis of the hollow body 1100 as possible. The smaller the intake angle of the channel opening 1102, the stronger the swirling flow. (See attached diagram.) Figure 3 The air intake angle of the passage 1102 refers to the angle D between the path of the second air intake passage 1101 through the side wall of the first chamber 1301 to form the passage 1102 and the tangent at the circumference of the passage 1102, which satisfies: 0°≤D<90°. As an example, the angle D can be 15°, 30°, 45° or 60°, etc.

[0057] In some embodiments, the second air intake channel 1101 penetrates the inner wall of the hollow body 1100 and forms a channel opening 1102 tangentially along the inner wall of the hollow body 1100. In this case, the extension path of the second air intake channel 1101 forming the channel opening 1102 is a tangential path, and the air intake angle is 0°. The second air intake channel 1101 to the first chamber 1301 is a tangential air intake and forms a swirling flow, causing the airflow to diffuse outward due to centrifugal force, ultimately resulting in a uniform airflow distribution. This helps the airflow to uniformly enter the aerosol forming product and fully carry out the atomized aerosol.

[0058] Specifically, the second air intake passage 1101 penetrates the side wall of the first chamber 1301 and forms a channel opening 1102 tangential to the side wall of the first chamber 1301. The airflow entering the first chamber 1301 can flow along the side wall of the first chamber 1301, thereby forming a swirling flow in the first chamber 1301. Alternatively, the second air intake passage 1101 penetrates the side wall of the second chamber 1302 and forms a channel opening 1102 tangential to the side wall of the second chamber 1302.

[0059] In some embodiments, at least two second air intake channels 1101 are provided, each second air intake channel 1101 is independent of each other, and each second air intake channel 1101 is distributed circumferentially at intervals on the sidewall of the hollow body 1100. Correspondingly, the channel openings 1102 formed by each second air intake channel 1101 on the sidewall of the first chamber 1301 or the second chamber 1302 are distributed circumferentially at intervals.

[0060] Furthermore, each of the second air intake channels 1101 is distributed at equal intervals along the circumference, so that the channel openings 1102 are distributed at equal intervals along the circumference.

[0061] Regarding the arrangement of the second air intake channel 1101 on the side wall of the hollow body 1100, at least the following alternative embodiments exist.

[0062] In some alternative embodiments, the second air intake passage 1101 is formed as an annular passage in the sidewall of the hollow body 1100, and each passage opening 1102 is connected to the annular passage.

[0063] In some embodiments, the second air intake channel 1101 forms a second notch on the outer wall of the hollow body 1100, and the second air intake channel 1101 forms a third notch on the end face of the hollow body 1100 away from the aerosol forming article.

[0064] In an example where the second air intake channel 1101 is set to be independent of each other, the second air intake channel 1101 extends from the outer side wall of the hollow body 1100 to the inner side wall, and the second air intake channel 1101 extends to the end face of the hollow body 1100 away from the end of the aerosol forming article.

[0065] In this case, the second air intake channel 1101 forms a second notch on the outer wall of the hollow body 1100, a third notch is formed on the end face of the hollow body 1100 away from the aerosol forming article, and a channel opening 1102 is formed on the inner wall. The path of the second air intake channel 1101 through the side wall of the hollow body 1100 is the formation path of the channel opening 1102.

[0066] In the example where the second air intake channel 1101 is configured as an annular channel, the sidewalls of the hollow body 1100 are partially thinned and an open annular region is formed on the outer side.

[0067] In this case, although the second air intake channel 1101 does not have a specific structure of a second or third notch, it functions as a second and third notch in the open annular area formed on the outer wall of the hollow body 1100 and the end face away from the aerosol forming article.

[0068] Regarding the arrangement of the second air intake channel 1101 on the outer wall of the hollow body 1100, at least the following alternative embodiments exist.

[0069] In some alternative embodiments, the second air intake passage 1101 forms a second notch on the outer wall of the hollow body 1100.

[0070] In some alternative embodiments, the second air intake channel 1101 forms a third notch on the end face of the hollow body 1100 away from the aerosol forming article.

[0071] Based on the above description of the support component 1000, the following is a supplementary description of the structure of the electronic atomizing device, listing the following three air intake methods for the electronic atomizing device. It should be noted that the following descriptions are illustrative and not specific limitations on the air intake methods of the electronic atomizing device.

[0072] In some embodiments, the bottom of the electronic atomizing device is provided with a third air intake channel, which extends to the second chamber 1302. Airflow enters the second chamber 1302 through the third air intake channel, and the airflow in the second chamber 1302 enters the first chamber 1301 through the first air intake channel 1201 and the second air intake channel 1101, respectively. The airflow entering the first chamber 1301 through the second air intake channel 1101 can form a swirling flow in the first chamber 1301.

[0073] Understandably, in conjunction with the appendix Figure 4 and attached Figure 5 A portion of the airflow in the second chamber 1302 passes through the first air intake channel 1201 and enters the first chamber 1301. Another portion of the airflow enters the second air intake channel 1101 from the channel opening 1102 on the side wall of the second chamber 1302, and then enters the first chamber 1301 from the channel opening 1102 and forms a swirling flow.

[0074] In related technologies, the air intake of the heating chamber 2100 in the electronic atomizing device is mainly a central airflow. This central airflow carries away most of the atomized aerosol. However, the area near the inner wall of the heating chamber 2100 lacks airflow, making it difficult for the atomized aerosol near the inner wall to escape. This atomized aerosol gradually condenses and accumulates on the inner wall of the heating chamber 2100. The condensate adsorbed on the side wall not only reduces the amount of smoke from the electronic atomizing device but also affects the dielectric constant of the heating element 2000, thus reducing high-frequency heating performance. Furthermore, the condensate corrodes the heating element 2000, thereby shortening the lifespan of the electronic atomizing device.

[0075] It should be noted that if the electronic atomizing device uses radio frequency heating (i.e., the heating element 2000 heats the aerosol-forming product in the heating chamber 2100 via microwaves), the outer temperature of the aerosol-forming product is higher than the inner temperature, resulting in a more pronounced condensation phenomenon and more condensate adhering to the inner wall of the heating chamber 2100. In this case, the electronic atomizing device uses a central airflow combined with a swirling airflow intake method, which can effectively drive the airflow to flow evenly and reduce condensation.

[0076] In some alternative embodiments, a fourth air intake channel is provided at the bottom of the electronic atomizing device or on the side wall along the first direction, the fourth air intake channel extending to the second air intake channel 1101. Specifically, the fourth air intake channel extends to the second notch.

[0077] In this case, the airflow enters the second intake passage 1101 from the fourth intake passage, combined with the attached... Figure 4 and attached Figure 6A portion of the airflow enters the first chamber 1301 through the channel opening 1102 on the side wall of the first chamber 1301 and forms a swirling flow. Another portion of the airflow enters the second chamber 1302 through the channel opening 1102 on the side wall of the second chamber 1302, and then passes through the first air intake channel 1201 before entering the first chamber 1301. The air intake method of the support member, by combining swirling flow with central airflow, improves the uniformity of airflow distribution within the aerosol-formed product.

[0078] In some alternative embodiments, a fourth air intake channel is provided on the sidewall of the electronic atomizing device along the first direction, and the fourth air intake channel extends to the second air intake channel 1101. Specifically, the fourth air intake channel extends to the third notch.

[0079] It should be noted that the above three air intake methods are all air intake methods that combine swirling flow with central airflow. The central airflow can compensate for the slow flow velocity in the central region when swirling flow is used, and swirling flow can compensate for the uneven airflow distribution when central airflow is used. Therefore, the electronic atomizing device in this application combines swirling flow with central airflow.

[0080] The structure of support member 1000 will be further described below.

[0081] In some embodiments, the total airflow of the first air intake channel 1201 is A, and the total airflow of each second air intake channel 1101 at the channel opening 1102 of the first chamber 1301 is B, satisfying: A≤B, so as to ensure that the airflow forms a vortex in the first chamber 1301 with sufficient intensity and improve the uniformity of airflow distribution in the first chamber 1301.

[0082] Understandably, the airflow rate is related to the cross-sectional area of ​​the air intake channel. Designing the total airflow rate of each second air intake channel 1101 to be no less than the total airflow rate of the first air intake channel 1201 ensures that the sum of the cross-sectional areas of each second air intake channel 1101 is no less than the sum of the cross-sectional areas of the first air intake channel 1201. Especially when the electronic atomizing device has bottom air intake, this is beneficial for diverting the airflow in the central area of ​​the second chamber 1302 to the second air intake channel 1101.

[0083] In some embodiments, the baffle 1200 is provided with at least two through holes serving as a first air intake channel 1201, with the through holes spaced apart to improve the uniformity of airflow and the flow velocity in the central region. Further, the baffle 1200 is configured as a perforated plate.

[0084] Specifically, the through holes are arranged in an array on the partition plate 1200, or the through holes are arranged radially along the circumference of different radii on the partition plate 1200.

[0085] It should be noted that the partition 1200 is integrally formed with the hollow body 1100, or the partition 1200 is installed in the inner cavity of the hollow body 1100.

[0086] Regarding the structure of the hollow body 1100, at least the following alternative embodiments exist to achieve uniform air intake from the support member 1000 into the heating chamber 2100.

[0087] In some alternative embodiments, in conjunction with the appendix Figure 4 and attached Figure 7 The hollow body 1100 does not have a partition 1200 in its inner cavity, and the cylindrical inner cavity of the hollow body 1100 is formed as a chamber that runs through both ends.

[0088] In this case, the side wall of the hollow body 1100 has a second air intake channel 1101. The second air intake channel 1101 forms a channel opening on the inner side wall of the hollow body 1100. The path of the second air intake channel 1101 through the inner side wall of the hollow body 1100 to form the channel opening does not intersect with the central axis of the hollow body 1100 in the length direction.

[0089] It is understandable that the airflow enters the second intake passage 1101 from the fourth intake passage, combined with the attached... Figure 7 The airflow enters the chamber through the channel opening on the inner wall of the hollow body 1100 and forms a swirling flow. Then the airflow flows from the chamber of the hollow body 1100 to the heating chamber 2100.

[0090] In some embodiments, at least two protruding structures 1103 are provided on one end of the hollow body 1100 for abutting the aerosol forming article. The protruding structures 1103 protrude along a first direction on the end face of the hollow body 1100, and each protruding structure 1103 is distributed circumferentially on the end face of the hollow body 1100.

[0091] Furthermore, the first chamber 1301 is located near the end of the hollow body 1100 where the protruding structure 1103 is located. The protruding structure 1103 has an abutment surface for abutting the aerosol-forming article. The end of the hollow body 1100 supports the aerosol-forming article through the protruding structure 1103, thereby reducing the contact area between the hollow body 1100 and the aerosol-forming article.

[0092] It is understandable that a recessed area 1104 is formed on the end face of the hollow body 1100 between two adjacent protruding structures 1103, and a concave-convex shape is formed on the end face of the hollow body 1100 facing the heating chamber 2100 along the circumference.

[0093] In some examples, the recessed area 1104 forms a first notch on both the inner and outer sidewalls of the hollow body 1100, so that the recessed area 1104 can be formed as a notch penetrating the sidewall of the hollow body 1100, and a hollow support structure is formed at the end of the hollow body 1100. Then, the airflow of the first chamber 1301 can flow to the recessed area 1104 and enter the aerosol forming article, ensuring that the airflow can be evenly filled to all parts of the aerosol forming article, and improving the aerosol transmission efficiency and thus improving the atomization amount of the product.

[0094] It should be noted that, while ensuring the support member 1000 provides stable support for the aerosol-forming product and has sufficient mechanical strength, the airflow in the periphery is significantly improved. Specifically, the total area of ​​the contact surfaces of each protruding structure 1103 does not exceed 50% of the area of ​​the end face of the protruding structure 1103 on the hollow body 1100, ensuring sufficient airflow through the recessed area 1104 and maintaining the structural strength of the protruding structure 1103. On the other hand, when the first chamber 1301 forms a swirling flow, the airflow can flow more evenly and fully to the recessed area 1104, allowing the airflow to enter the interior from the periphery of the end face of the aerosol-forming product, increasing the peripheral air intake and improving the atomization effect.

[0095] It is understandable that the area of ​​the end face of the hollow body 1100 is equal to the area of ​​the annular shape of the sidewall cross-section.

[0096] In some embodiments, to reduce the contact area between the protruding structure 1103 and the end of the aerosol-forming article, the protruding structure 1103 is formed with a larger near end and a smaller far end to increase the area of ​​the recessed region 1104, thereby allowing more airflow to enter the aerosol-forming article from the recessed region 1104. Specifically, the protruding end of the protruding structure 1103 is designated as the distal end, and the end of the protruding structure 1103 connected to the hollow body 1100 is designated as the proximal end.

[0097] Specifically, the sidewall of the protruding structure 1103 is formed as an inclined surface at least on the outer side of the hollow body 1100. Further, the protruding structure 1103 is formed as a trapezoidal boss, which has inclined surfaces on both the outer and inner sides of the hollow body 1100, and the inclined surfaces serve as the chamfered surfaces of the trapezoidal boss.

[0098] Regarding the shape of the inclined surface formed by the protruding structure 1103, at least the following alternative embodiments exist.

[0099] In some alternative embodiments, the trapezoidal boss has an inclined surface on the outside of the hollow body 1100.

[0100] In some alternative embodiments, the protrusion structure 1103 is formed as a conical boss, the outer surface of which is an inclined conical surface.

[0101] Regarding the shape of the protrusion structure 1103, which is larger in the near direction and smaller in the far direction, at least the following alternative embodiments exist.

[0102] In some alternative embodiments, the protrusion structure 1103 is formed as a stepped boss, and the side of the stepped boss is formed in a stepped shape to form a protrusion structure 1103 that is larger in the near and smaller in the far.

[0103] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
