Description

Technical Field

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

[0002] A portable fan is a small, portable fan that is typically designed to fit comfortably in the hand for easy carrying. Its main function is to provide users with portable airflow anytime, anywhere to lower the temperature or provide a cooling sensation.

[0003] Portable fans typically have a wire passage and an opening at the grille of the fan casing, which makes it easy for airflow to be blown into the wire passage through the opening, creating turbulence. Therefore, improvements are urgently needed. Utility Model Content

[0004] Therefore, it is necessary to provide a fan device to address the above problems, which aims to effectively prevent airflow from blowing into the cable passage through the opening and causing turbulence.

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

[0006] This application provides a fan device, which includes a fan duct and a sealing member. The fan duct has a grid with a wire passage and an opening communicating with the rear side of the wire passage. The sealing member is inserted into the fan duct radially and blocks the opening.

[0007] In one embodiment, the sealing member is inserted radially into the cable passage adjacent to the opening.

[0008] In one embodiment, the side of the sealing member closest to the axis of the air duct is flush with the side of the grille closest to the axis of the air duct.

[0009] In one embodiment, the position on the outer periphery of the air duct adjacent to the wire passage is formed as a limiting surface, and the sealing member abuts against the limiting surface.

[0010] In one embodiment, the outer periphery of the air duct is provided with two first plug-in portions, both of which are located on the limiting surface and are respectively disposed on both sides of the width direction of the wire passage. The two sides of the sealing member in the width direction are provided with second plug-in portions, and each second plug-in portion is plugged into and engaged with the corresponding first plug-in portion.

[0011] In one embodiment, a recessed area is formed on the outer periphery of the air duct, and the limiting surface and the first insertion portion are both located within the recessed area.

[0012] In one embodiment, the fan device further includes a housing that is fitted over the air duct. The housing has a clearance opening that is positioned opposite to the cable passage. The sealing member passes through the clearance opening radially along the air duct and is then inserted into the air duct.

[0013] In one embodiment, the sealing element also engages with the clearance opening.

[0014] In one embodiment, the duct also has a clearance opening, which is connected to the wire passage through the opening;

[0015] The fan device further includes a fan module disposed inside the air duct. The fan module is connected to a connector via a wire harness. The size of the wire harness is smaller than the through-passage size of the wire passage, and the size of the connector is larger than the through-passage size of the wire passage but smaller than the through-passage size of the clearance opening, so that the wire harness can be threaded into the wire passage after the connector passes through the clearance opening.

[0016] This application also provides a portable fan, which includes a fan assembly as described above and a handheld part, the fan assembly being connected to the handheld part.

[0017] Compared with the prior art, the embodiments of this application have the following advantages: This application uses a duct with a wire-passing channel and an opening connected to the rear side of the wire-passing channel in the duct's grille. The sealing member is inserted radially into the duct and seals the opening. This allows the opening to be sealed after the wire passes through the channel, effectively preventing airflow from blowing into the wire-passing channel and causing turbulence. Furthermore, the sealing member can be easily installed and removed by inserting and pulling it radially along the duct, making installation and removal convenient. Attached Figure Description

[0036] 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.

[0037] 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.

[0038] This application provides a fan device that, based on the existing wire passage and opening in the fan duct's grille, adds a sealing member. The sealing member is inserted radially into the fan duct and seals the opening, effectively preventing airflow from blowing through the opening into the wire passage and causing turbulence. Furthermore, the sealing member can be easily installed and removed by inserting and pulling it radially along the fan duct.

[0039] 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.

[0040] Please see Figure 1 and Figure 2 This application provides a fan device 100, which includes a fan duct 10 and a sealing member 20.

[0041] The ventilation duct 10 provides an installation location for the sealing component 20 and other components. The ventilation duct 10 has many shapes, including standard cylindrical, square, and other regular cylindrical shapes, as well as other irregular cylindrical shapes. Furthermore, the ventilation duct 10 can be formed in many ways. It can be a single, complete cylindrical component formed by machining, molding, 3D printing, or other processing methods. The ventilation duct 10 can also be assembled from multiple structural components. In this article, "multiple" refers to two or more structural components that are fixed together by fastening, bonding, ultrasonic welding, etc. The ventilation duct 10 can also be formed in other ways, which are not specifically limited here.

[0042] In this embodiment, the air duct 10 is arranged in a straight line, with its two ends along the axial direction used for air inlet and outlet, respectively, to achieve straight airflow. In other embodiments, the air duct 10 may also be arranged in other shapes such as L-shape or curved shape.

[0043] The duct 10 has a grid 13 with a wire passage 13a and an opening 13b communicating with the rear side of the wire passage 13a. Specifically, the duct 10 includes a base 11, a cylindrical body 12 surrounding the base 11, and a plurality of grids 13 connecting the outer periphery of the base 11 and the inner periphery of the cylindrical body 12. One of the plurality of grids 13 is hollow to form a wire passage 13a and an opening 13b communicating with the rear side of the wire passage 13a. For ease of description, the grid 13 with the wire passage 13a and the opening 13b is named wire passage grid 13' and is distinguished by different reference numerals. In addition, the base 11 is tapered so that the base 11 can guide the airflow.

[0044] Preferably, the rear side of the wire guide grille 13' extends beyond the rear side of the base 11. Obviously, the rear side of the wire guide channel 13a also extends beyond the rear side of the base 11. This arrangement can, on the one hand, increase the length of the wire guide grille 13' in the axial direction of the air duct 10, that is, increase the guide length of the wire guide grille 13' for the air blown out by the fan module 30, thereby facilitating the air blowing of the fan device 100; on the other hand, it expands the space of the wire guide channel 13a, making it easier to pass wires.

[0045] The sealing element 20 is inserted radially into the air duct 10 and seals the opening 13b. Specifically, the sealing element 20 seals the entire opening 13b, thus achieving the best sealing effect. Alternatively, the sealing element 20 can be part of the sealing opening 13b. Furthermore, the air duct 10 and the sealing element 20 are designed as two independent components, facilitating the replacement of the sealing element 20.

[0046] It is understandable that the insertion direction of the sealing component 20 is perpendicular to the wind direction inside the air duct 10, and the insertion strength of the sealing component 20 and the air duct 10 is greater than the wind force blowing towards the grille 13, so that the sealing component 20 will not be blown down into the wire passage 13a by the airflow and the opening 13b will be open. Specifically, when the sealing component 20 is inserted into the air duct 10 radially, the air duct 10 correspondingly limits the sealing component 20 axially to ensure that the sealing component 20 will not be loosened by the airflow.

[0047] The sealing component 20 can be inserted directly into the air duct 10 along its radial direction, or it can be inserted into the air duct 10 at a slight inclination along its radial direction. The sealing component 20 can be a solid structure or a hollow structure, and no specific limitation is made here.

[0048] In this embodiment, the sealing member 20 and the air duct 10 are fitted with a small interference fit. This design ensures the airtightness of the connection between the sealing member 20 and the air duct 10, preventing airflow from leaking into the cable passage 13a through the gap between the sealing member 20 and the air duct 10. It also facilitates the installation and removal of the sealing member 20. In other embodiments, the sealing member 20 and the air duct 10 can be fitted with a large interference fit.

[0049] Obviously, the sealing element 20 can be elastic or inelastic. When the sealing element 20 is elastic, both sides of the sealing element 20 that are arranged opposite to each other will form elastic pressure with the air duct 10, which can enhance the sealing performance of the connection between the sealing element 20 and the air duct 10. No specific limitation is made here.

[0050] With the above technical solution, when installing the sealing component 20, it is inserted into the air duct 10 radially, thus sealing the opening 13b, thereby completing the installation of the sealing component 20. When removing the sealing component 20, it is pulled off the air duct 10 radially, thus completing the removal of the sealing component 20. This design allows for easy installation and removal of the sealing component 20 simply by inserting and removing it radially along the air duct 10. Furthermore, by sealing the opening 13b during installation, the sealing component 20 effectively prevents airflow from being blown into the cable passage 13a through the opening 13b, thus avoiding turbulence.

[0051] Further, please refer to Figure 2 and Figure 3 The fan device 100 also includes a fan module 30 disposed within the air duct 10. During installation, the wiring harness 31 of the fan module 30 is first passed through the opening 13b into the wiring channel 13a. Then, the sealing member 20 is inserted into the air duct 10 radially and seals the opening 13b. Furthermore, the sealing member 20 can press against the wiring harness 31 passing through the wiring channel 13a, that is, press the wiring harness 31 along the axial direction of the air duct 10, preventing the wiring harness 31 from swinging within the wiring channel 13a during use and reducing the noise generated by the swinging friction between the wiring harness 31 and the wiring channel 13a.

[0052] The fan module 30 is inserted into the air duct 10, making it easy to install and remove. The fan module 30 consists of the duct body and other airflow guiding structures such as the motor and fan blades housed within the duct body, which will not be described in detail here. In addition, the fan module 30 can also be installed into the air duct 10 by means of fixed connection such as adhesive or welding, or by means of detachable connection such as magnetic connection, snap-fit ​​connection, or tenon and mortise connection.

[0053] Preferably, the rear side of the substrate 11 is provided with a chamber 11a communicating with the wire passage 13a. This arrangement allows a portion of the wire harness 31 to be housed within the chamber 11a while passing through the wire passage 13a, facilitating the passage of the wire harness 31. Furthermore, the electronic components of the fan module 30 extend into the chamber 11a, resulting in a compact structure for the fan device 100 and promoting its miniaturization.

[0054] To facilitate positioning of the fan module 30 after it is inserted into the air duct 10, please refer to [link / reference]. Figure 2 and Figure 3 In one embodiment of this application, a limiting end face 10a is formed on the inner periphery of the air duct 10. The limiting end face 10a is flush with the opening 13b on the rear side of the wire passage 13a. The fan module 30 abuts against the limiting end face 10a. With this configuration, when the fan module 30 is inserted into the air duct 10, the fan module 30 is first inserted into the air duct 10, and then the fan module 30 is moved along the axial direction of the air duct 10 until the fan module 30 abuts against the limiting end face 10a. This confirms that the fan module 30 has been installed in place, and the fan module 30 can be positioned after it is inserted into the air duct 10.

[0055] There are many possible positions for the plugging component 20 to be inserted into the ventilation duct 10 described above. Please refer to [link / reference needed]. Figure 1 and Figure 2 In one embodiment of this application, the sealing member 20 is inserted radially into the wiring channel 13a adjacent to the opening 13b. With this arrangement, no new space needs to be created. The existing wiring channel 13a can be used to provide the position required for the sealing member 20 to be inserted, thereby simplifying the structure of the ventilation duct 10.

[0056] In other embodiments, the sealing member 20 may also be inserted radially along the duct 10 into the position adjacent to the opening 13b of the clearance opening 10d, which will be described below.

[0057] Of course, in some embodiments, the sealing member 20 can also be plugged into the wire passage 13a to block the wire passage 13a and the opening 13b, and the sealing member 20 can be radially penetrated along the air duct 10 to form a wire passage. In this case, the wire harness 31 of the fan module 30 is passed through the wire passage.

[0058] Considering that if there is a gap between the side of the sealing element 20 near the axis of the air duct 10 and the side of the wire guide grille 13' near the axis of the air duct 10, turbulence may easily occur in the airflow at that gap. Therefore, please refer to... Figure 1In one embodiment of this application, the side of the sealing member 20 near the axis of the air duct 10 is flush with the side of the wire grid 13' near the axis of the air duct 10. This arrangement can effectively avoid the turbulence caused by the gap between the side of the sealing member 20 near the axis of the air duct 10 and the side of the wire grid 13' near the axis of the air duct 10.

[0059] To facilitate positioning of the sealing component 20 after it is inserted into the air duct 10, please refer to [link / reference needed]. Figure 2 and Figure 4 In one embodiment of this application, a limiting surface 10b is formed on the outer periphery of the air duct 10 adjacent to the wire passage 13a. The sealing member 20 abuts against the limiting surface 10b. With this configuration, when the sealing member 20 is inserted into the air duct 10, the sealing member 20 is first inserted into the wire passage 13a, and then the sealing member 20 is moved radially along the air duct 10 until the sealing member 20 abuts against the limiting surface 10b. This confirms that the sealing member 20 has been installed in place, and the sealing member 20 can be positioned after it is inserted into the air duct 10.

[0060] Further, please refer to Figure 2 and Figure 4 The outer periphery of the ventilation duct 10 is provided with two first insertion parts 101. Both first insertion parts 101 are located on the limiting surface 10b and are respectively located on both sides of the width direction of the wire passage 13a. The sealing member 20 is provided with second insertion parts 21 on both sides of the width direction. Each second insertion part 21 is inserted and engaged with the corresponding first insertion part 101. This arrangement can fix the sealing member 20 when it is inserted into the ventilation duct 10 in the radial direction and can restrict the sealing member 20 from moving in the axial direction of the ventilation duct 10.

[0061] Specifically, the air duct 10 and the first insertion part 101 are integrally formed, and the sealing member 20 and the second insertion part 21 are integrally formed. This enhances the connection strength between the air duct 10 and the first insertion part 101, as well as the connection strength between the sealing member 20 and the second insertion part 21. Furthermore, the air duct 10 and the first insertion part 101, and the sealing member 20 and the second insertion part 21, can also be configured as either fixedly connected or detachably connected, as described in the above embodiments.

[0062] In this embodiment, please refer to Figure 2 and Figure 4 The first insertion part 101 includes two insertion blocks 1011 arranged in parallel, and the second insertion part 21 is a plate-shaped insertion structure. Each second insertion part 21 is inserted between the corresponding two insertion blocks 1011. In other embodiments, the first insertion part 101 may be configured as an insertion groove, and the second insertion part 21 may be a columnar insertion structure that is inserted and cooperates with the insertion groove.

[0063] Furthermore, please refer to Figure 1 and Figure 4 A recessed area 10c is formed on the outer periphery of the air duct 10. The limiting surface 10b and the first plug-in part 101 are both located in the recessed area 10c. This arrangement ensures that the setting of the limiting surface 10b and the first plug-in part 101 will not increase the size of the air duct 10, thus making the structure of the fan device 100 compact and facilitating the miniaturization of the fan device 100.

[0064] Please see Figure 1 , Figure 4 as well as Figure 5 In one embodiment of this application, the fan device 100 further includes a housing 40, which is sleeved on the outside of the air duct 10. The housing 40 has a clearance opening 40a, which is positioned opposite to the wire passage 13a. The sealing member 20 passes through the clearance opening 40a radially along the air duct 10 and is inserted into the air duct 10, so that the air duct 10 can be supported by the housing 40.

[0065] Further, please refer to Figure 1 , Figure 4 as well as Figure 5 The sealing member 20 also engages with the clearance opening 40a, enabling the sealing member 20 to connect the air duct 10 and the outer casing 40, thereby enhancing the fixing strength between the air duct 10 and the outer casing 40. Specifically, the two second insertion parts 21 that are far apart abut against the two sides of the clearance opening 40a in the width direction, thus enabling the sealing member 20 to engage with the clearance opening 40a.

[0066] Further, please refer to Figure 3 The fan device 100 also includes an air inlet shroud 50 and an air outlet guide ring 60. The air inlet shroud 50 and the air outlet guide ring 60 are detachably mounted on the two ends of the housing 40 in the axial direction. The air duct 10 is sandwiched between the air inlet shroud 50 and the air outlet guide ring 60. The specific method of detachment is set with reference to the detachable connection method in the above embodiment, which will not be described in detail here. This setting can enhance the fixing strength of the air duct 10.

[0067] Please see Figure 1 and Figure 3 In one embodiment of this application, the duct 10 further has a clearance opening 10d located behind the wire passage 13a, and the clearance opening 10d and the wire passage 13a are connected through an opening 13b; the fan module 30 is connected to a connector 32 through a wire harness 31, the size of the wire harness 31 is smaller than the passage size of the wire passage 13a, and the size of the connector 32 is larger than the passage size of the wire passage 13a and smaller than the passage size of the clearance opening 10d, so that the wire harness 31 can be inserted into the wire passage 13a after the connector 32 passes through the clearance opening 10d.

[0068] With the above technical solution, the electrical connection between the fan module 30 and the electronic part in the handheld part 200 can be achieved simply by connecting the connector 32 to the electronic part in the handheld part 200, making the connection between the fan module 30 and the electronic part in the handheld part 200 convenient.

[0069] Preferably, the electronic components within the handheld unit 200 are provided with a connector (not shown), and the connector 32 of the fan module 30 is plugged into the connector, thus facilitating the connection between the connector 32 and the electronic components within the handheld unit 200. Furthermore, the connection between the connector 32 and the electronic components within the handheld unit 200 can also be achieved through either a fixed connection or a detachable connection as described above.

[0070] Please see Figure 3 and Figure 6 This application also provides a portable fan 1000, which includes a fan device 100 and a handheld part 200 as described above, with the fan device 100 connected to the handheld part 200. The specific structure of the fan device 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.

[0071] The connection between the outer casing 40 of the fan device 100 and the handheld part 200 can be set as a fixed connection or a detachable connection as described in the above embodiments, and will not be elaborated here.

[0072] Obviously, the embodiments described above are only some embodiments of this application, not all embodiments. The accompanying drawings show preferred embodiments of this application, but do not limit the patent scope of this application. This application can be implemented in many different forms; rather, the purpose of providing these embodiments is to provide a more thorough and comprehensive understanding of the disclosure of this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing specific embodiments, or make equivalent substitutions for some of the technical features. Any equivalent structures made using the content of this application's specification and drawings, directly or indirectly applied to other related technical fields, are similarly within the scope of patent protection of this application.
