Description

Technical Field

[0001] This application relates to a connection component and a fan, and is applicable to the technical field of fans. Background Technology

[0002] The connection between the base and column of existing fans is generally achieved through threads. For example, Chinese patent CN111682335A discloses a plug-in fan with a lower mating plate inside the base and an upper mating plate inside the column. A spring pin is located at the bottom of the upper mating plate, and a contact point is located on the opposite side of the lower and upper mating plates. The column is mounted on the base via a tube cap and a threaded triangular nut, allowing the spring pin and contact point to connect via a plug-in connection. This design, requiring a threaded connection between the column and base via a triangular nut, is structurally complex, inconvenient to disassemble and assemble, increases costs, and affects product packaging and transportation. Furthermore, this plug-in electrical connection method requires plugging before rotation, making the plug prone to twisting or damage during rotation due to friction between the contact surfaces or the operator's force, resulting in a decreased user experience. Moreover, threaded connections do not allow for the placement of other sealing components on the threaded connection surface; otherwise, threaded rotation would be impossible, leading to air leakage at the threaded connection surface. Utility Model Content

[0003] The purpose of this application is to design a connecting component and a fan, which uses a technical solution of rotating first and then electrically connecting, aiming to solve the problems of complex structure, poor sealing, and easy damage to the plug due to rotation in the existing connecting components that connect electrically first and then rotate.

[0004] This application relates to a connection assembly, which includes a base assembly and a column assembly. The base assembly includes a first connector and a first conductive element, and the column assembly includes a second connector and a second conductive element. The first connector and the second connector are rotatably connected, and after the first connector and the second connector are rotatably connected, the first conductive element and the second conductive element are electrically connected.

[0005] The first connecting member has a first air duct, and the second connecting member has a second air duct. When the first connecting member and the second connecting member are rotatably connected, the first air duct and the second air duct are connected. The first connecting member and the second connecting member can be detachably connected by a snap-fit ​​structure. The snap-fit ​​structure can include a snap-fit ​​groove and a boss; the boss and the snap-fit ​​groove are engaged. The first connecting member can be a support frame, and the second connecting member can be a connecting seat. The first conductive element is disposed on the support frame, and the second conductive element is disposed on the connecting seat. The first conductive element can be a contact plate, and the second conductive element can be a conductive plate. The conductive plate is pressed onto the connecting seat by a conductive plate pressure plate. The base assembly can also include a sealing ring, which is disposed on the support frame, and the contact plate is sandwiched between the sealing ring and the support frame. A limiting member can also be provided between the support frame and the connecting seat. A sealing element can also be provided between the first connecting member and the second connecting member.

[0006] This application also provides a fan, including the connection assembly as described above, and the base assembly may also include a blower.

[0007] In some embodiments, the fan further includes an air outlet, the column assembly includes a column and the air outlet is disposed on the column; the base assembly further includes a base housing, a first connector is disposed inside the base housing, and a fan is also disposed inside the base housing.

[0008] The connecting assembly provided in this application, through a design where the first and second connectors achieve electrical connection only after rotation, facilitates disassembly and assembly, and is convenient for packaging and transportation. It avoids the problem of friction or torsional damage caused by rotation between existing connectors. Furthermore, it improves the sealing performance between the first and second connectors, making it possible to install seals at the connection surfaces, resulting in a better sealing effect on the air ducts where the first and second connectors intersect. The fan provided in this application, by adopting the above-mentioned connecting assembly, simplifies the product structure, reduces costs, facilitates product packaging and transportation, effectively prevents damage to electrical connectors, and enhances the product's user experience.

[0022] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be arbitrarily combined with each other.

[0023] like Figure 3-5As shown, this application provides a connecting assembly, which includes a base assembly 1 and a column assembly 2. The base assembly 1 includes a first connector and a first conductive element, the first conductive element being disposed on the first connector. The column assembly 2 includes a second connector and a second conductive element, the second conductive element being disposed on the second connector. Specifically, the first connector and the second connector are rotatably connected to electrically connect the first conductive element and the second conductive element. The connecting assembly provided in this application is designed with the first and second connectors directly rotatably connected, which facilitates disassembly and assembly, packaging and transportation, and has a relatively simple and practical structure, and can easily achieve electrical connection.

[0024] like Figure 9 As shown, in some embodiments, the first connector is a support frame 13, and a first air duct 18 is provided on the first connector. Accordingly, refer to Figure 6 As shown, the second connector is a connector 25, and a second air duct 251 is provided on the second connector. Specifically, when the support frame 13 and the connector 25 are rotated together, the first air duct 18 is connected to the second air duct 251 to achieve air guidance. Further, the column assembly 2 also includes a column 21, and the air duct in the column 21 is connected to the second air duct 251 of the connector 25. The connecting assembly provided in this application, by rotating and snapping together the first connector and the second connector, can achieve better sealing between the first connector and the second connector compared to a threaded connection, thereby avoiding air leakage in the air duct structure between the first connector and the second connector. Preferably, a sealing element can also be provided between the first connector and the second connector to further improve the sealing between them.

[0025] like Figure 6 , 9As shown in Figures 11 and 12, in some embodiments, the first connecting member is a support frame 13, on which a support wall 131 is provided. The first air duct is vertically positioned at the center of the support frame 13 and located inside the support wall 131. The second connecting member is a connecting seat 25, on which the second air duct is vertically positioned at the center of the connecting seat 25. The support wall 131 and the connecting seat 25 are detachably snapped together by a snap-fit ​​structure. Specifically, the snap-fit ​​structure includes a snap-fit ​​groove and a boss 221, with the boss 221 engaging with the snap-fit ​​groove. For example, the snap-fit ​​groove is located on the side wall of the support wall 131, and the boss 221 is located on the side wall of the connecting seat 25. Further, the snap-fit ​​groove includes an insertion groove 132 and a locking slot 133, preferably, the insertion groove 132 and the locking slot 133 are interconnected. The boss 221 can be inserted vertically into the insertion slot 132 and engaged with the locking slot 133 by rotating clockwise, thereby achieving a sealed connection. Preferably, to improve the stability and sealing of the engagement, at least three bosses 221 are designed. Using the above scheme, the support frame 13 and the connecting seat 25 are connected together by insertion and rotation, achieving a sealed connection and preventing air leakage in the duct.

[0026] like Figure 6 , 8 As shown in Figures 9 and 12, in some embodiments, the first conductive element is disposed on the support frame 13, and the second conductive element is disposed on the connecting seat 25. Specifically, the first conductive element is a contact plate 15, which can be a copper plate structure. The contact plate 15 is disposed on the support frame 13 and can be disposed on the end face inside the support wall 131. The second conductive element is a conductive plate 23, which is disposed on the connecting seat 25 and can be disposed on the bottom surface of the connecting seat 25. Specifically, the contact plate 15 is provided with a contact groove, and the conductive plate 23 is provided with a retractable copper needle 231. Using the above scheme, when the connecting seat 25 is engaged with the support frame 13 by rotation, the copper needle 231 can rotate to the position of the contact groove and make contact with the contact groove, thereby achieving electrical connection.

[0027] like Figure 5 , 6 As shown in Figure 8, in some embodiments, the column assembly 2 further includes a conductive plate pressure plate 24, which is pressed onto the connecting seat 25, with the conductive plate 23 sandwiched between the conductive plate pressure plate 24 and the connecting seat 25. Preferably, the conductive plate pressure plate 24 has an annular structure and a through hole, allowing the copper needle 231 to pass through. By adopting the above scheme, the conductive plate pressure plate 24 is designed to press the conductive plate 23 onto the connecting seat 25, making the connection and fixation of the conductive plate 23 more reliable, and also strengthening the connection seat 25, preventing damage caused by excessive rotation of the connection seat 25.

[0028] like Figure 4 ,5 As shown in Figure 9, in some embodiments, the base assembly 1 further includes a sealing ring 14, which can be a silicone ring. The sealing ring 14 is disposed on the support frame 13, and the contact plate 15 is clamped between the sealing ring 14 and the support frame 13. This allows the support frame 13 and the connecting seat 25 to clamp together when engaged, preventing air leakage between the support frame 13 and the connecting seat 25. Specifically, the contact plate 15 can be clamped between the sealing ring 14 and the end face of the support frame 13. Figure 10 As shown, the sealing ring 14 is provided with an opening groove 141, which is adapted to the contact plate 15 so that the copper needle 231 on the conductive plate 23 can pass through the opening groove 141 and contact the contact plate 15.

[0029] like Figure 7-9 As shown, in some embodiments, to prevent accidental disassembly between the support frame 13 and the connecting seat 25, the support frame 13 and the connecting seat 25 are detachably connected by a limiting member. The limiting member can prevent accidental operation, and unlocking and locking marks are provided on the column base 22. Specifically, the limiting member includes an elastic limiting pin 16 and a limiting groove 222, which are adapted to each other. Preferably, the limiting groove 222 is provided on the column base 22 and is opposite to the limiting pin 16. The limiting pin 16 is provided on the support frame 13 and can elastically extend and retract relative to the support frame 13. With the above solution, when the support frame 13 and the connecting seat 25 are rotated to a preset angle for clamping, the limiting pin 16 and the limiting groove 222 can be engaged together to achieve locking. When unlocking is required, the limiting pin 16 can be squeezed along the limiting groove 222 by a pin to disengage it from the limiting groove 222, and then the connecting seat 25 can be rotated to achieve unlocking.

[0030] like Figure 1-5 As shown, this application also provides a fan, including a connecting component, which is the connecting component described above. Preferably, the fan provided in this application is a bladeless fan, and the connecting component can be disposed at the connection between the base and the column, or at the connection between the base or column and the fan blade assembly, or any other part suitable for rotational electrical connection.

[0031] like Figure 1-5As shown, in some embodiments, the fan further includes an air outlet 3. The column assembly 2 includes a column 21 and a column base 22, with the column 21 mounted on the column base 22 and the air outlet 3 mounted on the column 21. The air duct within the column 21 communicates with the air duct within the column base 22, and the air duct within the air outlet 3 communicates with the air duct within the column 21. The base assembly 1 also includes a base housing 11 and a top cover 12. A first connecting member is disposed within the base housing 11, and an air inlet is provided on the side of the base housing 11. The top cover 12 is fitted onto the support frame 13. A fan is also provided within the base housing 11, which rotates to generate airflow into the first air duct of the first connecting member.

[0032] The connecting assembly provided in this application is designed to be directly rotatably connected to the first and second connecting parts, which facilitates disassembly and assembly, packaging and transportation, and enables electrical connection; it also improves the sealing performance between the first and second connecting parts, resulting in a better sealing effect of the air ducts mating inside the first and second connecting parts.

[0033] The fan provided in this application, by adopting the above-mentioned connecting components, can simplify the product structure, reduce costs, facilitate product packaging and transportation, and effectively improve the airflow effect, thereby enhancing the product's user experience.
