Description

Technical Field

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

[0002] With the iterative updates of fans, portable fans have emerged, which are composed of a stand and a fan body. When in use, the stand is worn on the body, and the fan body can blow air vertically upwards.

[0003] The drawback of the existing technology is that, since the fan body blows air vertically upwards, that is, the fan body blows air directly upwards, the air blown out by the fan body can only cover a local area directly above, and the blowing effect is generally poor, so it is urgent to improve it. Utility Model Content

[0004] Therefore, it is necessary to provide a bracket to address the above problems, which aims to expand the area covered by the air blown by the fan body, thereby enhancing the air blowing effect of the fan body.

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

[0006] This application provides a bracket for use with a fan body. The bracket has an installation side and a fitting side arranged at an angle. The installation side is used to connect to the fan body, and the fitting side is used to fit against the user's body.

[0007] In one embodiment, the distance between the mounting side and the mating side gradually decreases from bottom to top.

[0008] In one embodiment, the distance between the mounting side and the mating side gradually increases from bottom to top.

[0009] In one embodiment, the mounting side is used to be detachably connected to the fan body, and the detachable connection between the mounting side and the fan body has at least two different relative positions;

[0010] When the mounting side and the fan body are in a first relative position, the distance between the mounting side and the contact side gradually decreases from bottom to top.

[0011] When the mounting side and the fan body are in a second relative position, the distance between the mounting side and the contact side gradually increases from bottom to top.

[0012] In one embodiment, the included angle α between the mounting side and the mating side satisfies: α≦15 degrees.

[0013] In one embodiment, the bracket has a wearable portion.

[0014] In one embodiment, the bracket has a clearance opening and a hanging cord protrusion, the hanging cord protrusion being located within the clearance opening, and the hanging cord protrusion and the clearance opening forming a hanging cord gap, the hanging cord gap including an inlet gap and a suspension gap communicating with the inlet gap, the clearance opening, the hanging cord protrusion, and the hanging cord gap forming the wearable part.

[0015] In one embodiment, the bracket has wearing positions on both the top and bottom sides.

[0016] In one embodiment, the edge region of the bonding side is positioned lower than the middle region of the bonding side.

[0017] This application also provides a portable fan, which includes a bracket as described above and a fan body, the fan body being connected to the mounting side.

[0018] Compared with the prior art, the embodiments of this application have the following advantages: In this application, the bracket has an installation side and a fitting side arranged at an angle, the installation side is used to connect with the fan body and the fitting side is used to fit against the user's body. When the fan body is connected to the installation side and the user wears the bracket so that the fitting side fits against the body, the fan body can be tilted upward to blow air, so that the air blown by the fan body can be diffused at a certain angle to form a wider fan-shaped coverage area, thereby expanding the area that the air blown by the fan body can cover, so as to enhance the blowing effect of the fan body.

Detailed Implementation

[0027] 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.

[0028] 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.

[0029] This application provides a bracket that, by setting the bracket to have an installation side and a fitting side arranged at an angle, allows the fan body to blow air upwards at an unconventional angle when connected to the installation side. This causes the air blown out by the fan body to spread at a certain angle, forming a wider fan-shaped coverage area, thereby expanding the area that the air blown out by the fan body can cover and enhancing the blowing effect of the fan body.

[0030] 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.

[0031] Please see Figure 1 and Figure 2This application provides a bracket 10, which provides an installation position for the fan body 20 described below. The bracket 10 has an installation side 10a and a fitting side 10b arranged at an angle. The installation side 10a is used to connect to the fan body 20, and the fitting side 10b is used to fit against the user's body.

[0032] The support 10 can take many shapes, including regular shapes such as cuboid, frustum, and prism, as well as other irregular shapes. No specific limitation is made here.

[0033] There are many ways to form the bracket 10. The bracket 10 can be integrally formed by injection molding, 3D printing or other methods. This setting can not only enhance the structural strength and sealing performance of the bracket 10, but also form all parts of the bracket 10 in one process. The bracket 10 can also be formed by connecting multiple shell parts. In this article, "multiple" refers to at least two. Multiple shell parts can be fixed by bonding, welding or other fixed connection methods. Multiple shell parts can also be fixed by detachable connection methods such as snap-fit, magnetic connection, buckle connection, threaded connection or other detachable connection methods.

[0034] The number of mounting side 10a and mating side 10b can be set to one or more, and the mounting side 10a and mating side 10b can be set in a one-to-one or many-to-one manner; similarly, the mounting side 10a and the fan body 20 can also be set in a one-to-one or many-to-one manner, without any specific limitation here. Figure 2 The diagram shows a case where the mounting side 10a, the mating side 10b, and the fan body 20 are all configured as one.

[0035] Obviously, when the mounting side 10a and the mating side 10b are set at an angle, the mounting side 10a and the mating side 10b can be set as two connected surfaces, or they can be set as two unconnected surfaces, such as two surfaces set opposite each other. No specific limitation is made here. Figure 1 The image shows a case where the mounting side 10a and the mating side 10b are two surfaces that are arranged opposite to each other.

[0036] In this embodiment, both the mounting side 10a and the fitting side 10b are designed as flat surfaces. This design facilitates the processing and shaping of the mounting side 10a and the fitting side 10b, and also ensures optimal fit between the fitting side 10b and the user's body, making it easy for the fitting side 10b to adhere to the user's body. In other embodiments, both the mounting side 10a and the fitting side 10b may also be designed as slightly curved surfaces.

[0037] In this embodiment, the mounting side 10a and the contact side 10b are set at an acute angle. This arrangement allows the airflow from the fan body 20 to have a larger horizontal velocity component, rising vertically while spreading horizontally. Furthermore, the acute-angled airflow experiences slower velocity decay due to gravity during propagation, enabling the effective airflow to be delivered over a longer distance. In other embodiments, the angle between the mounting side 10a and the contact side 10b can also be an obtuse angle. Correspondingly, the mounting side 10a can be located above or below the contact side 10b.

[0038] Furthermore, the included angle α between the mounting side 10a and the mating side 10b satisfies: α≦15 degrees. With this setting, when the fan body 20 is connected to the mounting side 10a, it can be ensured that the fan body 20 can always cover the user's neck and head when blowing air upwards at an angle.

[0039] Optionally, the included angle α between the mounting side 10a and the mating side 10b is selected from any one or a range formed by any two of the following: 1 degree, 2 degrees, 3 degrees, 4 degrees, 5 degrees, 6 degrees, 7 degrees, 8 degrees, 9 degrees, 10 degrees, 11 degrees, 12 degrees, 13 degrees, 14 degrees, and 15 degrees.

[0040] Preferably, the angle α between the mounting side 10a and the mating side 10b is 3 degrees. With this setting, the area covered by the air blown out by the fan body 20 can be expanded, while the air delivery distance of the fan body 20 can be shortened.

[0041] There are many ways to connect the bracket 10 and the fan body 20. The bracket 10 and the fan body 20 can be integrally formed by injection molding, 3D printing or other methods to connect the mounting side 10a and the fan body 20. Alternatively, the bracket 10 and the fan body 20 can be fixedly connected by bonding, welding or other methods to connect the mounting side 10a and the fan body 20. Or, the bracket 10 and the fan body 20 can be detachably connected by plugging, snapping, magnetic connection, buckle connection, threaded connection or other methods to connect the mounting side 10a and the fan body 20.

[0042] Specifically, the bracket 10 is plate-shaped and has a connecting side 10c that connects the mounting side 10a and the mating side 10b. The connecting side 10c surrounds the mounting side 10a and the mating side 10b, which enhances the structural strength of the bracket 10.

[0043] With the above technical solution, since the mounting side 10a and the fitting side 10b of the bracket 10 are set at an angle, when in use, the fan body 20 is connected to the mounting side 10a, and the user wears the bracket 10 on his body, with the fitting side 10b fitting against his body. This allows the fan body 20 to tilt upwards and blow air, causing the air blown by the fan body 20 to spread at a certain angle, forming a wider fan-shaped coverage area. This expands the area that the air blown by the fan body 20 can cover, thereby enhancing the blowing effect of the fan body 20.

[0044] Considering that the mounting side 10a and the mating side 10b are set at an angle, they have sides with a smaller gap and sides with a larger gap in the extending direction. When the bracket 10 has the side with the smaller gap on top and the side with the larger gap on the bottom, the fan body 20, after being connected to the mounting side 10a, can tilt and blow air towards the user; when the bracket 10 has the side with the larger gap on top and the side with the smaller gap on the bottom, the fan body 20, after being connected to the mounting side 10a, can tilt and blow air away from the user. If the fan body 20 can be switched between tilting and blowing air towards the user and tilting and blowing air away from the user, the user can adjust the airflow direction of the fan body 20 according to their usage needs. Therefore, please refer to... Figures 2 to 4 In one embodiment of this application, the mounting side 10a is detachably connected to the fan body 20, and the detachable connection between the mounting side 10a and the fan body 20 has at least two different relative positions; when the mounting side 10a and the fan body 20 are in the first relative position, the distance between the mounting side 10a and the mating side 10b gradually decreases from bottom to top. Figure 3 (middle); when the mounting side 10a and the fan body 20 are in the second relative position, the distance between the mounting side 10a and the mating side 10b gradually increases from bottom to top. Figure 4 middle).

[0045] Obviously, the air outlet 20a of the fan body 20 is parallel to the extension direction of the mounting side 10a, so as to ensure that the angle between the mounting side 10a and the mating side 10b is the actual air outlet angle of the air outlet 20a.

[0046] In this embodiment, the bracket 10 and the fan body 20 are magnetically connected, allowing the mounting side 10a and the fan body 20 to be detachably connected. This arrangement ensures that the mounting side 10a and the fan body 20 can be detachably connected in both the first and second relative positions, while also facilitating the assembly and disassembly of the bracket 10 and the fan body 20. Obviously, the bracket 10 and the fan body 20 can also be connected using other detachable connection methods described in the above embodiments to achieve the same detachable connection, which will not be elaborated upon here.

[0047] Using the above technical solution, when it is necessary to switch the fan body 20 from tilting towards the user to tilting away from the user, firstly, detach the fan body 20 from the bracket 10. Next, remove the bracket 10 from the body and flip it vertically, changing it from "the side with the smaller gap is on top, and the side with the larger gap is on the bottom" to "the side with the larger gap is on top, and the side with the smaller gap is on the bottom." Then, put on the bracket 10, ensuring the fitting side 10b fits snugly against the body. Finally, detachably connect the fan body 20 to the mounting side 10a. This allows the fan body 20 to switch from tilting towards the user to tilting away from the user. Obviously, the principle is the same when switching the fan body 20 from tilting away from the user to tilting towards the user, and will not be repeated here.

[0048] In some embodiments, the distance between the mounting side 10a and the mating side 10b can also be maintained as a gradually decreasing distance from bottom to top. In this case, the mounting side 10a and the fan body 20 can be fixedly connected or detachably connected.

[0049] In other embodiments, the distance between the mounting side 10a and the mating side 10b can always be set to gradually increase from bottom to top. In this case, the mounting side 10a and the fan body 20 can be fixedly connected or detachably connected.

[0050] In other embodiments, the mounting side 10a and the fan body 20 may also have a third relative position. When the mounting side 10a and the fan body 20 are in the third relative position, the bracket 10 is changed from vertical to horizontal, and the mounting side 10a and the contact side 10b are also changed from vertical to horizontal. The fan body 20 remains vertical. At this time, the mounting side 10a is magnetically connected to the middle position of the fan body 20 only at the middle position.

[0051] Preferably, see 2 and Figure 5The bracket 10 includes a front cover 11, a rear shell 12, and magnetic components 13. The front end of the rear shell 12 has an opening, and the front cover 11 covers the opening and presses the magnetic components 13 into the rear shell 12, thus facilitating the installation and removal of the magnetic components 13. The side of the front cover 11 facing away from the rear shell 12 forms the mounting side 10a, and the side of the rear shell 12 facing away from the front cover 11 forms the fitting side 10b. Four magnetic components 13 are provided, corresponding to the four corners near the bracket 10. Correspondingly, the fan body 20 has four magnetic structures, each of which is magnetically attracted to the corresponding magnetic component 13.

[0052] Obviously, regardless of whether the distance between the mounting side 10a and the mating side 10b is gradually decreasing or gradually increasing from bottom to top, each magnetic structure of the fan body 20 can be magnetically attracted to the corresponding magnetic component 13, so that the mounting side 10a can be detachably connected to the fan body 20 when the mounting side 10a and the fan body 20 are in the first relative position or the second relative position.

[0053] Further, please refer to Figure 5 The rear shell 12 is provided with multiple reinforcing ribs 121 arranged in a crisscross pattern, which can enhance the structural strength of the rear shell 12.

[0054] Furthermore, please refer to Figure 5 The rear shell 12 contains an assembly ring 122, and the magnetic component 13 mates with the assembly ring 122, thus facilitating the assembly and disassembly of the magnetic component 13. Clearly, the outer periphery of the assembly ring 122 is connected to the reinforcing rib 121 to enhance the structural strength of the assembly ring 122.

[0055] Please see Figure 6 In one embodiment of this application, the edge region of the contact side 10b is set lower than the middle region of the contact side 10b. With this setting, when using the portable fan 100, only the middle region of the contact side 10b is in contact with the user's body, reducing the contact area between the contact side 10b and the user's body, thereby improving the comfort when wearing the support 10.

[0056] For ease of use, please refer to the following instructions regarding the wearing of the bracket 10. Figure 6 In one embodiment of this application, the bracket 10 has a wearing part 10', which allows the user to wear the bracket 10 through the wearing part 10', making the bracket 10 easy to wear.

[0057] There are many types of wearing parts 10'. Wearing parts 10' can be a hanging cord structure. Accordingly, by threading the hanging cord through the hanging cord structure, the bracket 10 can be worn. Wearing parts 10' can also be an elastic clip. By clipping the elastic clip onto clothing, the bracket 10 can be worn. Wearing parts 10' can also be a strap hole. Accordingly, by threading the strap through the strap hole, the bracket 10 can be secured to the user.

[0058] Preferably, please refer to Figure 6 The bracket 10 has wearing parts 10' on both the upper and lower sides. With this configuration, the bracket 10 can be worn through the wearing parts 10' located above, regardless of whether the mounting side 10a and the fan body 20 are in the first relative position or the second relative position.

[0059] There are many ways to provide wearing portions 10' on both the upper and lower sides of the bracket 10. In this embodiment, the bracket 10 is configured such that the wearing portions 10' on both the upper and lower sides are provided on both the upper and lower sides of the fitting side 10b. With this configuration, the wearing portions 10' can be hidden within the fitting side 10b when the bracket 10 is worn. In other embodiments, the bracket 10 can also be configured such that the wearing portions 10' on both the upper and lower sides are provided on both the top and bottom of the connecting side 10c.

[0060] When the wearing part 10' is configured as a hanging cord structure, please refer to Figure 6 In one embodiment of this application, the bracket 10 has a clearance opening 10d and a hanging rope protrusion 101. The hanging rope protrusion 101 is located inside the clearance opening 10d, and the hanging rope protrusion 101 and the clearance opening 10d surround to form a hanging rope gap 101a. The hanging rope gap 101a includes an inlet gap 1011a and a suspension gap 1012a communicating with the inlet gap 1011a. The clearance opening 10d, the hanging rope protrusion 101, and the hanging rope gap 101a form a wearing part 10'. With this arrangement, when hanging the hanging rope, it is only necessary to pass the rope through the inlet gap 1011a and extend it into the suspension gap 1012a to hang the rope on the hanging rope protrusion 101, thereby achieving the fixation of the rope and making the fixing of the hanging rope convenient.

[0061] The clearance opening 10d and the hanging rope protrusion 101 are both located on the mating side 10b. The bracket 10 partially passes through to form the clearance opening 10d. The hanging rope protrusion 101 is integrally formed with the bracket 10, which can enhance the connection strength between the hanging rope protrusion 101 and the bracket 10.

[0062] Specifically, please refer to Figure 6The two sides of the hanging rope protrusion 101 in the width direction are spaced apart from the two sides of the relief opening 10d in the width direction and form a hanging gap 1012a. One end of the hanging rope protrusion 101 in the length direction is connected to an inner wall in the length direction of the relief opening 10d, and the other end of the hanging rope protrusion 101 in the length direction is spaced apart from another inner wall in the length direction of the relief opening 10d and forms an inlet gap 1011a.

[0063] Further, please refer to Figure 6 The fitting side 10b has two wearing parts 10' arranged horizontally at intervals on both the upper and lower sides. This arrangement allows the two ends of the hanging rope to be suspended in the two wearing parts 10' located at the top, making it convenient to hang the hanging rope.

[0064] Please see Figure 2 This application also provides a portable fan 100, which includes a bracket 10 and a fan body 20 as described above, with the fan body 20 connected to the mounting side 10a. The specific structure of the bracket 10 is as described in the above embodiments. Since the portable fan 100 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.

[0065] Obviously, the bracket 10 and the fan body 20 can be directly magnetically attached together. In this case, a wearable structure is needed to wear the bracket 10 on the body. Alternatively, the bracket 10 can be located inside the user's clothing, and the fan body 20 can be located outside the user's clothing. When the bracket 10 and the fan body 20 are magnetically attached together, they can clamp the user's clothing. In this case, a wearable structure can be used or not.

[0066] 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.
