Description

Technical Field

[0001] This application relates to the technical field of fans, and more specifically, to a fan head and a portable fan. Background Technology

[0002] Portable fans typically have buttons, displays, and other functional components installed inside the casing to enable device operation, status display, and other functions.

[0003] The drawback of the existing technology is that, since the functional components are installed inside the housing, when disassembling or assembling the functional components, other parts on the housing must be removed first before the functional components can be inserted into the housing for disassembly or assembly, which makes the disassembly or assembly of the functional components inconvenient, and therefore urgently needs to be improved. Utility Model Content

[0004] Therefore, it is necessary to provide a fan head that facilitates the assembly and disassembly of functional components to address the aforementioned issues.

[0005] The embodiments of this application achieve the above objectives through the following technical solutions.

[0006] This application provides a fan head, which includes a fan housing and a functional component. The outer periphery of the fan housing has a mounting portion extending axially therefrom, and the functional component is mounted in the mounting portion through the outer side of the mounting portion.

[0007] In one embodiment, the mounting portion protrudes from the outer periphery of the fan housing, and the mounting portion is a long, annular structure.

[0008] The mounting part and the fan housing form a mounting groove, and the functional component cooperates with the mounting groove.

[0009] In one embodiment, the mounting groove includes a first groove and a second groove that are connected sequentially from the bottom of the groove to the opening of the groove, wherein the length of the first groove in the axial direction of the fan housing is less than the length of the second groove in the axial direction of the fan housing.

[0010] The functional components include a circuit board and a control panel. The circuit board mates with the first slot, and the control panel mates with the second slot.

[0011] In one embodiment, the fan housing has a positioning protrusion located at the bottom of the mounting groove, and the fan housing, the mounting portion, and the positioning protrusion surround to form a first groove and a second groove.

[0012] In one embodiment, the first groove includes a first section and a second section arranged sequentially along the axial direction of the fan housing, wherein the width of the first section is smaller than the width of the second section;

[0013] The circuit board includes a first part and a second part connected in sequence. The width of the first part is smaller than the width of the second part. The first part mates with the first segment, and the second part mates with the second segment.

[0014] In one embodiment, the control panel has two snap-fit ​​grooves on its inner side, and the fan housing has two snap-fit ​​protrusions. The two snap-fit ​​protrusions are located at the bottom of the first groove and on both sides of the width direction of the circuit board. Each snap-fit ​​protrusion cooperates with the corresponding snap-fit ​​groove.

[0015] In one embodiment, notches are provided on both sides of the circuit board in the width direction, and each of the snap-fit ​​protrusions is located within the corresponding notch.

[0016] In one embodiment, the fan housing is formed with a snap-fit, the snap-fit ​​being located on the groove wall on one side of the mounting groove along its length.

[0017] The control panel includes a button panel and a light-transmitting panel. One end of the button panel along its length is provided with a buckle that engages with the buckle. The other end of the button panel along its length is spliced ​​with one end of the light-transmitting panel along its length. The end of the light-transmitting panel away from the button panel abuts against the side of the second groove away from the buckle.

[0018] Furthermore, the button panel and the light-transmitting panel are respectively positioned relative to the button position and the display position of the circuit board.

[0019] In one embodiment, the width of the mounting portion gradually decreases from its direction of proximity to the fan housing to its direction of distance from the fan housing.

[0020] This application also provides a portable fan, which further includes a fan head and a handle as described above, the fan head being connected to the handle.

[0021] Compared with the prior art, the embodiments of this application have the following advantages: In this application, a mounting portion extending axially is formed on the outer periphery of the fan housing, and the functional component is mounted in the mounting portion through the outside of the mounting portion, so that the functional component can be disassembled and assembled directly through the outside of the mounting portion without extending into the fan housing, thereby making the disassembly and assembly of the functional component convenient.

[0051] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0052] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0053] This application provides a fan head in which a mounting portion extending axially is formed on the outer periphery of the fan housing, and a functional component is mounted inside the mounting portion through the outside of the mounting portion. This arrangement allows the functional component to be mounted in a non-traditional manner by directly mounting it through the outside of the mounting portion, thereby making the assembly and disassembly of the functional component convenient.

[0054] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0055] Please see Figures 1 to 3 This application provides a fan head 100, which includes a fan housing 10 and a functional component 20.

[0056] The fan housing 10 provides mounting positions for functional components 20, fan assemblies, and other parts. The fan housing 10 can have various shapes; in this embodiment, it is cylindrical, with its two axial ends forming an air inlet 10a and an air outlet 10b, thus facilitating the formation of these openings. In other embodiments, the fan housing 10 can also be square, spherical, or other regular or irregular shapes.

[0057] There are many ways to form the fan housing 10. In this embodiment, the fan housing 10 is integrally formed by injection molding, 3D printing, or other methods. This design enhances the structural strength and sealing performance of the fan housing 10, and allows all parts of the fan housing 10 to be formed in one process. In other embodiments, the fan housing 10 can also be formed by connecting multiple shell parts. "Multiple" in this document refers to at least two shell parts. These multiple shell parts can be fixed together by methods such as bonding or welding, or they can be fixed together by methods such as snap-fit, magnetic connection, or buckle connection.

[0058] The outer periphery of the fan housing 10 has a mounting portion 11 extending along its axial direction, and the functional component 20 is mounted inside the mounting portion 11 through the outside of the mounting portion 11.

[0059] The functional component 20 is used to realize human-computer interaction between the fan and the user. The functional component 20 includes, but is not limited to, interactive functions such as control function and display function. The control function enables the fan head 100 to be controlled, and the display function displays the operating parameters of the fan head 100. The operating parameters include, but are not limited to, one or more of the following: wind speed level, blowing mode, spray level, spray mode, power consumption, water volume, fan blade speed, time information, temperature information (such as ambient temperature, air outlet temperature, and other temperatures), and fault codes.

[0060] By way of example and not limitation, the mounting portion 11 may extend from one end of the outer periphery of the fan housing 10 to the other end of the outer periphery of the fan housing 10. Figure 1 This situation is illustrated in the figure; the mounting part 11 may also be located in the middle of the outer periphery of the fan housing 10; the mounting part 11 may also be located at the end of the outer periphery of the fan housing 10; the mounting part 11 may also extend from the middle of the outer periphery of the fan housing 10 to the end of the outer periphery of the fan housing 10.

[0061] There are many ways in which the mounting portion 11 extends along the axial direction of the fan housing 10. In this embodiment, the mounting portion 11 extends directly along the axial direction of the fan housing 10, which facilitates the processing and forming of the mounting portion 11. In other embodiments, the mounting portion 11 may also extend at a slightly inclined angle along the axial direction of the fan housing 10.

[0062] The number of mounting parts 11 and functional components 20 can be set to one or more. In this document, "multiple" refers to at least two. The mounting parts 11 and functional components 20 can be set in a one-to-one or one-to-many manner. For example, the mounting parts 11 and functional components 20 can both be set to one or more, and each functional component 20 can be installed in the corresponding mounting part 11. Or, the mounting part 11 can be set to one, and the functional components 20 can be set to two, with the two functional components 20 installed in the same mounting part 11. No specific limitation is made here.

[0063] With the above technical solution, a mounting portion 11 extending axially is formed on the outer periphery of the fan housing 10 in this application. The functional component 20 is mounted in the mounting portion 11 through the outside of the mounting portion 11, so that the functional component 20 can be installed and removed directly through the outside of the mounting portion 11 without extending into the fan housing 10, thereby making the installation and removal of the functional component 20 convenient.

[0064] Further, please refer to Figures 1 to 3The fan head 100 also includes an inner cylinder 30, an air inlet shroud 40, an air outlet shroud 50, and a fan assembly (not labeled). The outer peripheral wall of the inner cylinder 30 fits with the inner peripheral wall of the fan housing 10. The air inlet shroud 40 and the air outlet shroud 50 are respectively covered on the air inlet 10a and the air outlet 10b of the fan housing 10, and the fan housing 10 and the inner cylinder 30 are sandwiched between the air inlet shroud 40 and the air outlet shroud 50. The fan assembly consists of a motor and fan blades and is used to drive airflow to be drawn in from the air inlet shroud 40 and blown out through the inner cylinder 30 and the air outlet shroud 50.

[0065] Furthermore, please refer to Figure 2 and Figure 4 The fan housing 10 also has a connecting shell 12 located on its outer periphery. The electrical connection portion 60 of the fan head 100 is installed in the connecting shell 12. The electrical connection portion 60 is used to realize the electrical connection between the fan head 100 and the handle 200, which will be described below, making it easy to install the electrical connection portion 60 of the fan head 100. The fan housing 10 also has a first connecting port 10c that connects the inside of the fan housing 10 and the inside of the connecting shell 12. The corresponding position on the inner cylinder 30 is connected to the first connecting port 10c, which facilitates the connection of the fan assembly and the electrical connection portion 60 by wire.

[0066] There are many types of the aforementioned mounting section 11; please refer to [link / reference]. Figure 2 and Figure 5 In one embodiment of this application, the mounting part 11 protrudes from the outer periphery of the fan housing 10, and the mounting part 11 is a long strip-shaped annular structure; the mounting part 11 and the fan housing 10 surround to form a mounting groove 11a, and the functional component 20 cooperates with the mounting groove 11a.

[0067] Specifically, the mounting part 11 and the fan housing 10 are integrally formed, and the integral forming method is the same as that in the above embodiments, which will not be described in detail here. This can enhance the connection strength between the mounting part 11 and the fan housing 10 and the sealing performance at the connection. In addition, the mounting part 11 and the fan housing 10 can also be fixed by bonding, welding or other fixed connection methods, or by detachable connection methods such as snap-fit, magnetic connection, and buckle 2211 connection.

[0068] In this embodiment, the mounting portion 11 is a closed-loop annular structure, which ensures the sealing of the outer periphery of the mounting portion 11. In other embodiments, the mounting portion 11 may also be an open-loop annular structure.

[0069] Through the above technical solution, on the one hand, the functional component 20 is installed in the mounting groove 11a through the mounting part 11 on the side facing away from the fan housing 10, so that the functional component 20 will not be blocked by other components when it is disassembled and installed, making the disassembly and assembly of the functional component 20 convenient; on the other hand, the mounting part 11 protrudes from the outer periphery of the fan housing 10, making it easy for the user to touch the position of the functional component 20.

[0070] In other embodiments, the mounting portion 11 may also be configured as a groove-like structure recessed on the outer periphery of the fan housing 10; similarly, the mounting portion 11 may also be configured in other shapes such as wavy.

[0071] Furthermore, in order to enhance the structural strength of the mounting part 11 and facilitate its demolding, please refer to... Figure 1 The width of the mounting part 11 gradually decreases from the direction close to the fan housing 10 to the direction away from the fan housing 10. This configuration, on the one hand, makes the cross-section of the mounting part 11 in the radial direction of the fan housing 10 trapezoidal, thereby enhancing the structural strength of the mounting part 11; on the other hand, it makes a certain demolding slope on both sides of the width direction of the mounting part 11, thereby facilitating the removal of the mounting part 11 from the mold.

[0072] Obviously, the outer periphery of the mounting part 11 can be configured as a concave arc surface. Figure 1 This method is shown in the figure; the outer periphery of the mounting part 11 can also be a plane with an inclination. Both of the above methods can make the width of the mounting part 11 gradually decrease from the direction close to the fan housing 10 to the direction away from the fan housing 10. No specific limitation is made here.

[0073] Considering that functional component 20 includes circuit board 21 and control panel 22, reducing the size of circuit board 21 would both lower its manufacturing cost and weight. Please refer to [link to relevant documentation]. Figure 2 , Figure 3 as well as Figures 5 to 7 In one embodiment of this application, the mounting slot 11a includes a first slot 111a and a second slot 112a connected sequentially from its bottom to its opening. The length of the first slot 111a in the axial direction of the fan housing 10 is less than the length of the second slot 112a in the axial direction of the fan housing 10. The functional component 20 includes a circuit board 21 and a control panel 22. The circuit board 21 mates with the first slot 111a, and the control panel 22 mates with the second slot 112a. This arrangement significantly reduces the length of the circuit board 21 compared to the length of the control panel 22, thereby reducing the size of the circuit board 21 and lowering its manufacturing cost and weight. Obviously, the control panel 22 also abuts against the bottom of the second slot 112a, facilitating the determination of whether the control panel 22 is properly installed.

[0074] In this embodiment, one end of the first groove 111a and the second groove 112a is flush with each other along their length, while the other ends are offset along their length. This facilitates the molding of first grooves 111a and second grooves 112a of different lengths using a mold. In other embodiments, both ends of the first groove 111a and the second groove 112a may be offset along their length.

[0075] In other embodiments, the mounting slot 11a can also be configured as a slot, with the circuit board 21 engaging with the mounting slot 11a near the bottom of the slot, and the control panel 22 engaging with the mounting slot 11a near the opening.

[0076] Furthermore, please refer to Figure 2 as well as Figures 4 to 6 The fan housing 10 is also provided with a second communication port 10d that connects the interior of the fan housing 10 and the interior of the connecting shell 12. The inner peripheral wall of the fan housing 10 is provided with a wire passage 10e that extends circumferentially. One end of the wire passage 10e is connected to the bottom of the mounting groove 11a, and the other end of the wire passage 10e is connected to the second communication port 10d. With this configuration, when the circuit board 21 and the electrical connection part 60 are connected by the connecting wire 2101, one end of the connecting wire 2101 is first connected to the circuit board 21, and then the other end of the connecting wire 2101 is passed through the wire passage 10e and the second communication port 10d and connected to the electrical connection part 60, thereby facilitating the connection of the circuit board 21 and the electrical connection part 60 by the wire.

[0077] Furthermore, the inner cylinder 30 confines the connecting wire 2101 within the wire passage 10e, preventing the connecting wire 2101 from occupying additional space within the fan housing 10. Additionally, the first end of the connecting wire 2101 is fixedly connected to the functional component 20, while the second end is detachably connected to the electrical connection portion 60. This configuration allows for easy wiring of the fan head 100's circuitry; simply pass the second end of the connecting wire 2101 through the wire passage 10e and the second connection port 10d, and connect it to the electrical connection portion 60. Specifically, the connecting wire 2101 is located on the first portion 211 of the circuit board 21, which will be described below.

[0078] To further reduce the size of circuit board 21, please refer to... Figure 2 , Figure 3 as well as Figures 5 to 7In one embodiment of this application, the first groove 111a includes a first segment 1111a and a second segment 1112a arranged sequentially along the axial direction of the fan housing 10. The width of the first segment 1111a is smaller than the width of the second segment 1112a. The circuit board 21 includes a first part 211 and a second part 212 connected sequentially. The width of the first part 211 is smaller than the width of the second part 212. The first part 211 cooperates with the first segment 1111a, and the second part 212 cooperates with the second segment 1112a. This arrangement can effectively reduce the width of the first part 211 on the circuit board 21, thereby further reducing the size of the circuit board 21.

[0079] Further, please refer to Figure 5 In one embodiment of this application, the fan housing 10 has a positioning protrusion 13 located at the bottom of the mounting groove 11a. The fan housing 10, the mounting portion 11, and the positioning protrusion 13 surround and form a first groove 111a and a second groove 112a, thus facilitating the formation of the first groove 111a and the second groove 112a. The positioning protrusion 13, the fan housing 10, and the mounting portion 11 are integrally formed, thereby enhancing the structural strength of the positioning protrusion 13. Clearly, the bottom of the second groove 112a is located on the positioning protrusion 13.

[0080] Specifically, please refer to Figure 5 The positioning protrusion 13 includes a main body 131 and two extensions 132. The main body 131 and the circuit board 21 are arranged sequentially along the length direction of the mounting part 11, and the main body 131 is located inside one end of the mounting part 11 along the length direction. The two extensions 132 are arranged in parallel on the side of the main body 131 facing the circuit board 21, and both extensions 132 extend along the length direction of the mounting part 11. This arrangement allows the fan housing 10, the mounting part 11, and the positioning protrusion 13 to surround and form a first groove 111a and a second groove 112a, and the first groove 111a includes a first section 1111a and a second section 1112a.

[0081] To enhance the fixing strength of the control panel 22, please refer to Figure 5 and Figure 8 In one embodiment of this application, the control panel 22 has two snap-fit ​​grooves 22a on its inner side, and the fan housing 10 has two snap-fit ​​protrusions 14. The two snap-fit ​​protrusions 14 are located at the bottom of the first groove 111a and on both sides of the width direction of the circuit board 21. Each snap-fit ​​protrusion 14 cooperates with the corresponding snap-fit ​​groove 22a, thereby enhancing the fixing strength of the control panel 22. Specifically, the snap-fit ​​grooves 22a are located on the inner side of the button panel 221, which will be described below.

[0082] Further, please refer to Figure 5 and Figure 7The circuit board 21 has notches 21a on both sides in the width direction, and each snap-fit ​​protrusion 14 is located in the corresponding notch 21a. This arrangement allows the two snap-fit ​​protrusions 14 to limit the circuit board 21 along the width direction, thereby improving the stability of the circuit board 21. Specifically, the notch 21a is located in the first part 211 of the circuit board 21 near the second part 212.

[0083] For easier assembly and disassembly of control panel 22, please refer to [link / reference]. Figures 6 to 8 In one embodiment of this application, the fan housing 10 has a latch 10f located on the groove wall of the mounting groove 11a along its length. The control panel 22 includes a button panel 221 and a light-transmitting panel 222. One end of the button panel 221 along its length is provided with a latch 2211 that engages with the latch 10f. The other end of the button panel 221 along its length is spliced ​​with one end of the light-transmitting panel 222 along its length. The end of the light-transmitting panel 222 away from the button panel 221 abuts against the side of the second groove 112a away from the latch 10f. The button panel 221 and the light-transmitting panel 222 are respectively positioned opposite to the button position 21b and the display position 21c of the circuit board 21. The button position 21b is located in the second part 212 of the circuit board 21, and the display position 21c is located in the first part 211 of the circuit board 21.

[0084] Obviously, the button panel 221 can be located in front of the light-transmitting panel 222, or it can be located behind the light-transmitting panel 222. No specific limitation is made here.

[0085] Specifically, please refer to Figures 6 to 8 The button panel 221 has a recessed area 221a on its inner side, and a frustum-shaped abutting protrusion 2212 is provided in the recessed area 221a. The abutting protrusion 2212 is positioned opposite to the button position 21b of the circuit board 21, thus facilitating pressing of the button position 21b of the circuit board 21 through the button panel 221. Furthermore, in this embodiment, the display position 21c of the circuit board 21 is configured as a plurality of indicator lights arranged sequentially along the length of the mounting portion 11. In another embodiment, the display position 21c of the circuit board 21 can also be configured as a display screen.

[0086] Further, please refer to Figures 6 to 8 The functional component 20 also includes a light-concentrating cover 23, which has multiple light-concentrating holes 23a. The light-concentrating cover 23 cooperates with the first section 1111a, and each indicator light is located in the corresponding light-concentrating hole 23a, thus achieving the function of light concentration.

[0087] With the above technical solution, when installing the control panel 22, first engage the clip 2211 on the button panel 221 with the latch 10f, then connect one end of the light-transmitting panel 222 to the end of the button panel 221 away from the clip 2211, and simultaneously abut the end of the light-transmitting panel 222 away from the button panel 221 to the side of the second groove 112a away from the latch 10f, thus allowing the control panel 22 to be installed in the second groove 112a; when disassembling the control panel 22, first pry the light-transmitting panel 222 out from between the button panel 221 and the side of the second groove 112a away from the latch 10f, and simultaneously disengage the light-transmitting panel 222 from the end of the button panel 221 away from the clip 2211, then pry the button panel 221 out from the second groove 112a, and simultaneously disengage the clip 2211 and the latch 10f, thus allowing the button panel 221 to be removed from the second groove 112a.

[0088] In other embodiments, the control panel 22 may also be configured to include only one of the button panel 221 and the light-transmitting panel 222.

[0089] Specifically, please refer to Figure 8 and Figure 9 The side of the button panel 221 away from the buckle 2211 is formed into an L-shaped first splice joint 221', with the inner corner of the first splice joint 221' facing away from the circuit board 21. The side of the light-transmitting panel 222 facing the control panel 22 is formed into an L-shaped second splice joint 222', with the inner corner of the second splice joint 222' facing the circuit board 21. The inner corners of the first splice joint 221' and the inner corners of the second splice joint 222' are joined together. This arrangement can increase the splicing stability of the button panel 221 and the light-transmitting panel 222.

[0090] Furthermore, the inner corner of the first splice 221' is chamfered to a right angle, and the inner corner of the second splice 222' is rounded. This arrangement ensures that the end of the first splice 221' and the rounded corner of the second splice 222' are in line contact, resulting in a relatively low contact strength between the first splice 221' and the second splice 222'. This facilitates the removal of the light-transmitting panel 222 from between the button panel 221 and the side of the second groove 112a away from the latch 10f.

[0091] In other embodiments, the side of the button panel 221 away from the buckle 2211 may be formed as the first splicing plane, and the side of the light-transmitting panel 222 facing the control panel 22 may be formed as the second splicing plane, with the second splicing plane abutting against the first splicing plane.

[0092] Please see Figure 1 , Figure 10 as well as Figure 11This application also provides a portable fan 1000, which includes a fan head 100 and a handle 200 as described above, with the fan head 100 connected to the handle 200. The specific structure of the fan head 100 is as described in the above embodiments. Since the portable fan 1000 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0093] Specifically, the handle 200 is configured as a portable power bank with a built-in rechargeable battery. The upper end of the handle 200 has a socket 200a and a charging port 200b. The lower end of the fan head 100 has a plug 101 that mates with the socket 200a. The plug 101 connects to the electrical connection portion 60 inside the connecting housing 12, thus providing the fan head 100 with the necessary power for operation via the handle 200. Furthermore, the lower end of the handle 200 has a charging cable 201 for charging other electronic devices such as mobile phones, tablets, and smartwatches. The connection method between the lower end of the fan head 100 and the upper end of the handle 200 is the same as the detachable connection method described in the above embodiment, and will not be elaborated further here.
