[0047] 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 invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
[0048] Example 1:
[0049] Please see Figures 1-4This embodiment provides a portable adjustable fan 100, including: a main body 1, a directional adjustment component 2, a baffle 3, and a knob assembly 4. By operating the knob assembly 4, the directional adjustment component 2 and the baffle 3 are driven respectively, so that the positions of the directional adjustment component 2 and the baffle 3 cooperate with each other, thereby adjusting the air volume and air direction of the fan.
[0050] Specifically, the main body 1 is a shell, with a receiving cavity 11 and an air outlet slot 12 communicating with the receiving cavity 11. In this embodiment, the air outlet slot 12 is located on the top of the main body 1. The adjusting member 2 is a cylindrical structure, rotatably mounted on the air outlet slot 12. The adjusting member 2 includes a first grille 21 and an air outlet 22 defined by the first grille 21. Rotating the adjusting member 2 also drives the first grille 21 to rotate, thereby adjusting the orientation of the air outlet 22 and determining the blowing direction of the airflow generated in the receiving cavity 11. A baffle 3 is rotatably mounted inside the adjusting member 2, and its width can block the inner side of the first grille 21. In this embodiment, the outer surface of the baffle 3 is in contact with the inner surface of the adjusting member 2, and the amount of airflow is controlled by the baffle 3 blocking or partially blocking the inner side of the first grille 21.
[0051] In this embodiment, the knob assembly 4 is rotatably disposed on both sides outside the air outlet slot 12, including a first knob 41 and a second knob 42. The first knob 41 drives the adjusting component 2 to rotate, and the second knob 42 drives the baffle 3 to rotate. In use, rotating the first knob 41 adjusts the air outlet direction of the fan, and rotating the second knob 42 controls the amount of air outlet.
[0052] When the portable adjustable fan 100 described in this embodiment is placed on a desktop or used as a handheld fan, the user generally needs to blow air perpendicular to or nearly perpendicular to the main body 1. At this time, such as Figure 1 The air outlet 22 shown is sufficient. Meanwhile, the baffle 3 is positioned away from the first grille 21, or the airflow cross-section of the first grille 21 can be adjusted as needed. When worn around the neck, the user prefers the airflow direction to be parallel to the main body 1, i.e., parallel to... Figure 3 The state setting of the adjusting component 2 shown can be achieved. At this time, the baffle 3 can be used to block the vertical space, ensuring that the airflow is concentrated and blown out from the air outlet 22.
[0053] By controlling the fan's airflow and direction using only the adjusting component 2 and the baffle 3, the problem of being unable to adjust the airflow direction and volume, or only being able to adjust the airflow direction locally, can be solved. This allows the portable adjustable fan 100 described in this embodiment to meet the airflow requirements of desktop placement, handheld use, and neck hanging. Furthermore, the adjusting component 2 and the baffle 3 are nested within the air outlet slot 12, effectively simplifying and miniaturizing the portable fan's airflow structure. While ensuring the fan's portability, this also provides space and possibilities for other functional systems, such as phone support and charging.
[0054] In some embodiments, the adjusting member 2 includes a second grille 23, which is arranged circumferentially with the first grille 21 along the rotation axis of the adjusting member 2. In this embodiment, the first grille 21 and the second grille 23 are adjacent. Figures 1-4 Based on this, refer to Figure 5 The second grille 23 can be considered an extension of the first grille 21. However, unlike the first grille 21, which defines the air outlet 22 and primarily adjusts the direction of the fan's airflow, the second grille 23 serves as an auxiliary structure for the adjusting member 2. This structure ensures the structural stability of the adjusting member 2 and also addresses the issue of the adjusting member 2 affecting the airflow into the air outlet slot 12 during rotation.
[0055] Continue reading Figures 1-5 Specifically, the second grille 23 is located between the air outlet slot 12 and the receiving cavity 11, or on the side of the air outlet slot 12 away from the receiving cavity 11. When the airflow direction is perpendicular to the main body 1, and the air outlet 22 is oriented perpendicular to the main body 1, the airflow flows from the receiving cavity 11 through the second grille 23 into the air outlet slot 12, and then flows from the air outlet slot 12 to the first grille 21 and the air outlet 22. When the airflow direction is parallel to the main body 1, and the second grille 23 is located on the side of the air outlet slot 12 away from the receiving cavity 11, the airflow effect can also be achieved. However, in order to meet the airflow velocity and air pressure requirements of the first grille 21, the baffle 3 rotates and blocks the second grille 23, so that the airflow is constrained and concentrated at the air outlet 22 to achieve the ideal airflow effect.
[0056] In other embodiments, the first grille 21 includes a first rib 211 and a second rib 212. The first rib 211 surrounds the air outlet 22, and the second rib 212 is circumferentially disposed in the air outlet 22 along the rotation axis of the directional member 2 and connected to the first rib 211. The first rib 211 and the second rib 212 form the air outlet structure. In this embodiment, the annular first rib 211 protrudes beyond the second rib 212, optimizing the mechanical effect of airflow at the air outlet 22, resulting in a more concentrated airflow. Furthermore, using an annular first rib 211 saves material compared to the traditional arrangement of multiple horizontal first ribs 211, reducing the weight of the first grille 21 and the overall weight of the fan.
[0057] The first rib 211 and the second rib 212 form an air duct 213, which divides the air outlet 22, optimizes the airflow of the air outlet 22, and strengthens the structural strength of the adjusting component 2 at the first grille 21.
[0058] In some embodiments, the main body 1 includes a first housing 13 and a second housing 14, which together form a receiving cavity 11. The second housing 14 has a surrounding edge 141 on one side of the air outlet slot 12, which partially obstructs the adjusting member 2. The first housing 13 and the second housing 14 facilitate the production and installation of the fan main body 1. The surrounding edge 141 on the second housing 14 provides greater coverage for the adjusting member 2 at the air outlet slot 12, limiting the range of rotation of the first grille 21 and protecting the adjusting member 2 from foreign objects.
[0059] Specifically, the portable adjustable fan 100 includes a fan 5, which is disposed in the receiving cavity 11 and fixed to the first housing 13. In design and manufacturing, the first housing 13 is provided with a mounting structure for fixing the fan 5. Within the receiving cavity 11, a chamber (not labeled) is also provided near the fan 5. The fan 5 generates airflow during operation, which, in conjunction with the chamber, pressurizes the air and blows it towards the air outlet slot 12. Of course, to improve portability, the fan 5 in this embodiment adopts a flat structure, allowing the main body 1 formed by the first housing 13 and the second housing 14 to be designed as a plate structure, making it convenient for users to place in a storage bag.
[0060] See Figure 1 and Figure 6 In a further embodiment, at the location of the fan 5, the first housing 13 and the second housing 14 are provided with air inlets 131 that communicate with the receiving cavity 11, or only one of the first housing 13 or the second housing 14 is provided with an air inlet 131 that communicates with the receiving cavity 11. By providing air inlets 131, airflow can enter the receiving cavity 11 through the air inlets 131 without damaging the cavities surrounding the fan 5, making its aerodynamic characteristics and the production of the fan components simpler and less costly. In this embodiment, both the first housing 13 and the second housing 14 are provided with air inlets 131, which avoids the blockage or obstruction of one air inlet 131 due to different application scenarios, reduces the wind resistance in the receiving cavity 11, and avoids problems such as overheating of the fan 5.
[0061] like Figure 6 As shown, in some embodiments, a support frame 142 is provided on the second housing 14 at the fan 5 position. One end of the support frame 142 is rotatably mounted on the second housing 14, and the other end is openable or closed, close to or away from the second housing 14. With the support frame 142, the fan can be tilted on a work surface such as a desktop without needing to be held by hand. In this embodiment, to lower the center of gravity and improve stability during tilting, the opening and closing rotation axis of the support frame 142 is perpendicular to the rotation axis of the adjusting member 2. The fan 5 is generally located in the middle of the main body 1, and the support is located at the fan 5 position. To ensure that the support position is consistent with the center of gravity, further improving support stability.
[0062] In this embodiment, the portable adjustable fan 100 also includes accessories such as a battery 101, a control circuit board 102, and a button 103. The battery 101 is disposed in the receiving cavity 11 and located on the side of the fan 5 away from the air outlet slot 12. In addition to providing power, the battery 101 also acts as a counterweight to some extent, making it easier to align the air outlet slot 12 upwards when suspended or held, and facilitating blind operation during use. The control circuit board 102 is disposed inside the side of the main body 1, specifically inside the connection between the first housing 13 and the second housing 14. The button 103 is located outside the side of the main body 1, passing through the main body 1 and abutting against the control circuit board 102. When the user holds the fan, their fingers can easily touch and press the button 103 to start, stop, or adjust the fan speed.
[0063] In summary, the portable adjustable fan provided by this utility model uses the first knob and the second knob to control the adjusting component and the baffle, respectively, to achieve different air volume and different air direction of the fan, thereby meeting the air output needs of the portable fan in various positions such as desktop placement, handheld, and neck hanging, and thus improving the utilization rate of the portable fan.
[0064] Secondly, the directional component and baffle are nested in the air outlet slot and are independently controlled by the first and second knobs, which simplifies and reduces the air outlet structure of the portable fan. While meeting the air outlet needs of various situations, the portability of the fan is guaranteed, and more space and possibilities are provided for other functional systems.
[0065] Example 2:
[0066] Please Figures 1-6 Based on this, refer to Figures 7-8 This embodiment improves upon the portable adjustable fan 100 provided in Embodiment 1. The difference lies in that the portable adjustable fan 100 in this embodiment includes magnetic components 6. Multiple magnetic components 6 are arranged in a ring or semi-ring shape within the first housing 13 and are located on the side of the fan 5 opposite to the air outlet slot 12. In this embodiment, the first housing 13 is provided with an arc-shaped groove 132 for accommodating the magnetic components 6, and the multiple magnetic components 6 are arranged within the arc-shaped groove 132 according to the characteristics of the magnets.
[0067] The portable adjustable fan 100, equipped with a magnetic attachment 6, can be used to hold a mobile phone 200 with magnetic attraction function, or a mobile phone 200 made of magnetically attractive material, so that the mobile phone 200 can be magnetically attached to the portable adjustable fan 100. Thus, this embodiment can provide cooling for the user while also serving as a mobile phone stand.
[0068] In other embodiments, since the magnetic attachment 6 is located near the battery 101, a wireless charging module (not labeled) can be provided in the middle of multiple magnetic attachments 6 to charge the mobile phone with wireless charging function while the mobile phone is fixed.
[0069] With the addition of the magnetic attachment 6, the portable adjustable fan 100 provided in this embodiment can increase its usage rate, as mobile phones are essential electronic products for users when they go out. It also reduces the need for users to carry phone holders, power banks, and other tools, making outings more convenient.
[0070] Example 3:
[0071] This embodiment is a further improvement and optimization based on Embodiment 1 or Embodiment 2. Please... Figures 1-8 Based on this, refer to Figure 9 The portable adjustable fan 100 in this embodiment differs from those in Embodiments 1 and 2 in that it also includes a lanyard 7. On the side near the knob assembly 4, the main body 1 is provided with a lanyard hole 15, and the lanyard 7 is inserted into the lanyard hole 15.
[0072] Specifically, in this embodiment, there are two lanyard holes 15, symmetrically arranged on both sides of the main body, that is, near the seam between the first housing 13 and the second housing 14, and near the knob assembly 4. The two ends of the lanyard 7 are generally soft ropes 71, which pass through the lanyard holes 15 and are fixed. The portable adjustable fan 100 is placed on the user's chest by hanging it around the neck with the lanyard 7. At this time, the first grille 21 is facing upwards towards the neck, and the second grille 23 is rotated to the side perpendicular to the main body 1 because of the first grille 21, which can be located on the side facing the chest or away from the chest. Preferably, the baffle 3 can rotate and block the second grille 23, so that the airflow is concentrated on the first grille 21 and blown out, making the "cooling feeling" at the neck better.
[0073] Of course, the second grille 23 can also be oriented towards the chest, with the baffle 3 rotated to the side opposite the second grille 23. Alternatively, the first grille 21 can be tilted towards the chest, allowing airflow to be directed towards the chest for cooling. This avoids situations where some users cannot directly direct the airflow onto their face, causing alternating hot and cold sensations that can lead to facial muscle spasms.
[0074] In other embodiments, there may be one or more hanging holes 15. After the hanging rope 7 is connected to the hanging hole 15, it can also be hung on the shoulder or the shoulder strap of a bag. The specific situation needs to be adjusted according to the needs, which will not be elaborated here.
[0075] With the addition of a lanyard 7, users can hang the fan during outdoor activities such as mountain climbing and hiking, or when both hands are unable to hold it. This further expands the application scenarios of the portable adjustable fan 100, enabling multiple uses and increasing fan utilization.
[0076] The above description is merely an example and illustration of the structure of this utility model, and while the description is quite specific and detailed, it should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these obvious substitutions all fall within the protection scope of this utility model.
