Detailed Implementation

[0032] 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.

[0033] 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.

[0034] This application provides a portable fan, which has a limiting structure formed in the fan housing adjacent to the display area. The limiting structure limits the displacement of the display module, so that the display module will not be displaced or fall off due to vibration, collision or external force during transportation, installation or use, and ensures that the display module is always in the correct position.

[0035] 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.

[0036] Please see Figures 1 to 3 This application provides a portable fan 100, which includes a fan housing 10 and a display module 20.

[0037] The fan housing 10 provides a mounting location for the display module 20 and other components, and the fan housing 10 has a display area 10a. The fan housing 10 can have many shapes, such as cuboid, cylindrical, prismatic, or other regular shapes, or other irregular shapes. Similarly, the display area 10a can also have many shapes, such as square, circular, rhomboid, or other regular shapes, or other irregular shapes. No specific limitation is made here.

[0038] There are many ways to form the fan housing 10. In this embodiment, the fan housing 10 includes a first housing 11 and a second housing 12 that are snap-fitted together, which makes it easy to assemble and disassemble the fan housing 10. In other embodiments, the fan housing 10 may also include two parts, which are fixed together by welding.

[0039] There are many possible positions for the display area 10a. In this embodiment, the display area 10a is located below the front of the fan housing 10. This allows the user to easily observe the display area 10a while ensuring that it is not obstructed by the fan blades 50, which will be described below. In other embodiments, the display area 10a may also be located in the center of the front of the fan housing 10, or it may be located on the back, upper, lower, left, or right side of the fan housing 10.

[0040] There are many ways to form the display area 10a. In this embodiment, the display area 10a is formed by the fan housing 10 extending from its inner wall to its outer wall, which makes the formation of the display area 10a convenient. In other embodiments, the display area 10a can also be formed by the fan housing 10 using a transparent or light-transmitting material.

[0041] The display module 20 is used to display relevant data of the portable fan 100. The content displayed by the display module 20 includes, but is not limited to, one or more of the following: wind speed setting, blowing mode, spray setting, spray mode, power status, water status, fan blade speed, time information, temperature information (such as ambient temperature, air outlet temperature, and other temperatures), and fault codes.

[0042] The display module 20 is disposed inside the fan housing 10, and the content displayed by the display module 20 can be displayed in the display area 10a.

[0043] Specifically, the display side of the display module 20 is positioned directly opposite the display area 10a so that the content displayed by the display module 20 is displayed in the display area 10a. Obviously, the display side of the display module 20 can be located within the display area 10a, or it can be spaced apart from the display area 10a; no specific limitation is made here.

[0044] There are many types of display modules 20. They can be character displays, graphic displays, or segment displays. No specific limitation is made here.

[0045] It is worth mentioning that the display module 20 can be set with multiple display areas. In this article, "multiple" refers to at least two display areas. Each display area displays different parameters. For example, the display module 20 is set with three display areas. The first display area is used to display "the indicator and value of the battery level" to clearly indicate the battery level. The second display area is used to display "the indicator and value of the wind speed" to clearly indicate the wind speed level. The third display area is used to simultaneously display the corresponding "indicator and value of the battery level or wind speed" to accurately display the battery level or wind speed. Under the premise of limited display area, the display content is maximized and the user experience is optimized.

[0046] A limiting structure 10' is formed inside the fan housing 10 adjacent to the display area 10a. Specifically, the limiting structure 10' and the display area 10a are located on the same inner wall, and the limiting structure 10' is disposed adjacent to the display area 10a. The display module 20 is at least partially limited within the limiting structure 10', and the outer peripheral wall of the display module 20 cooperates with the inner peripheral wall of the limiting structure 10'.

[0047] By way of example and not limitation, the display module 20 may be partially confined within the limiting structure 10' and partially outside the limiting structure 10'. For example, one-half or two-thirds of the display module 20 may be confined within the limiting structure 10', which can enhance the heat dissipation effect of the display module 20. Alternatively, the display module 20 may be entirely confined within the limiting structure 10'.

[0048] In this embodiment, the fan housing 10 and the limiting structure 10' are integrally formed, which enhances the connection strength between the fan housing 10 and the limiting structure 10'. This integral forming can be achieved through injection molding, 3D printing, or other methods. In other embodiments, the fan housing 10 and the limiting structure 10' can also be fixed by detachable connections such as snap-fit, buckle 701 connection, magnetic connection, tenon and mortise connection, or screw connection. Alternatively, they can be fixed by adhesive bonding, welding, or other fixed connections.

[0049] Furthermore, the portable fan 100 also includes a main control board 30, and a display module 20 is disposed on the main control board 30. The main control board 30 is installed in the fan housing 10 through the aforementioned detachable connection. The display module 20 can be confined within the limiting structure 10' when the main control board 30 is installed in the fan housing 10.

[0050] Through the above technical solution, a limiting structure 10' is formed within the fan housing 10 adjacent to the display area 10a. The display module 20 is at least partially confined within the limiting structure 10', thus restricting displacement of the display module 20. This effectively prevents displacement or detachment of the display module 20 during transportation, installation, or use due to vibration, collision, or external forces, ensuring that the display module 20 remains in the correct position. Furthermore, the limiting structure 10' is opaque, preventing light from scattering from the display module 20 and enhancing its display effect.

[0051] There are many types of the aforementioned limiting structure 10'; please refer to [link / reference]. Figure 2 and Figure 4In one embodiment of this application, the fan housing 10 has a mounting cavity 10b, which has a first inner wall 10c and a limiting wall 10d connected at an angle. The display area 10a is located on the first inner wall 10c, which forms a limiting frame 101. The limiting frame 101 and the limiting wall 10d surround and form a limiting structure 10'. This arrangement cleverly utilizes the characteristic of the limiting wall 10d inherent in the fan housing 10, and combines it with the limiting frame 101 to form the limiting structure 10', resulting in a cleverly formed limiting structure 10'. Obviously, both the limiting frame 101 and the limiting wall 10d are adjacent to the display area 10a.

[0052] In other embodiments, the limiting structure 10' may also be configured as an annular closed frame, with the frame surrounding and adjacent to the display area 10a; the limiting structure 10' may also be configured as multiple limiting protrusions, with the multiple limiting protrusions surrounding and adjacent to the display area 10a.

[0053] There are many types of the aforementioned limit frame 101; please refer to [link / reference]. Figure 4 In one embodiment of this application, the limiting frame 101 is U-shaped and has two parallel first limiting segments 1011 and a second limiting segment 1012 connecting the two first limiting segments 1011. The end of each first limiting segment 1011 furthest from the second limiting segment 1012 is connected to a limiting wall 10d to form a limiting structure 10'. This configuration allows the display module 20 to be limited in four directions around its periphery by the two first limiting segments 1011, the second limiting segment 1012, and the limiting wall 10d, ensuring the stability of the display module 20 when limited. Correspondingly, the display module 20 is cuboid in shape.

[0054] In other embodiments, the limiting frame 101 may also be arranged in an arc shape, with both sides in the length direction connected to the limiting wall 10d to form a limiting structure 10'; correspondingly, a portion of the display module 20 in the circumferential direction is arranged in an arc shape, and another portion is arranged in a straight line.

[0055] Considering that reducing the contact area between the limiting wall 10d and the display module 20, as well as the contact area between the limiting frame 101 and the display module 20, would increase the surface area of ​​the display module 20 exposed to air, thereby enhancing the heat dissipation effect of the display module 20, please refer to [the relevant documentation]. Figure 4In one embodiment of this application, the limiting wall 10d is provided with a first limiting protrusion 101d that abuts against the display module 20; the inner wall of the limiting frame 101 is provided with a second limiting protrusion 10101 that abuts against the display module 20. With this configuration, the first limiting protrusion 101d and the second limiting protrusion 10101 are provided to form heat dissipation gaps between the limiting wall 10d and the display module 20 and between the limiting frame 101 and the display module 20, thereby enhancing the heat dissipation effect of the display module 20.

[0056] Specifically, please refer to Figure 4 The limiting wall 10d is provided with two first limiting protrusions 101d, which are spaced apart along the length of the limiting wall 10d. The inner side of each first limiting segment 1011 and the inner side of each second limiting segment 1012 are also provided with two second limiting protrusions 10101 spaced apart along their length. This arrangement enhances the heat dissipation of the display module 20 and ensures the limiting effect of the limiting structure 10' on the display module 20. Alternatively, the limiting wall 10d may also have one first limiting protrusion 101d, and the inner side of each first limiting segment 1011 and the inner side of each second limiting segment 1012 may also have one second limiting protrusion 10101.

[0057] In other embodiments, the limiting wall 10d may only have a first limiting protrusion 101d that abuts against the display module 20; or the inner wall of the limiting frame 101 may only have a second limiting protrusion 10101 that abuts against the display module 20.

[0058] Further, please refer to Figure 4 The first limiting protrusion 101d is also connected to the first inner wall 10c, which can enhance the structural strength of the connection between the limiting wall 10d and the first inner wall 10c, thereby enhancing the structural strength of the fan housing 10.

[0059] Furthermore, please refer to Figure 4 The thickness of the second limiting protrusion 10101 is much smaller than the thickness of the limiting structure 10'. The thickness refers to the length of the limiting structure 10' from its inner side to its outer side. The side of the first limiting protrusion 101d away from the limiting wall 10d extends beyond the side of the display area 10a near the limiting wall 10d. The distance between the side of the first limiting protrusion 101d away from the limiting wall 10d and the side of the display area 10a near the limiting wall 10d is equal to the thickness of the second limiting protrusion 10101. This arrangement ensures that the arrangement of the first limiting protrusion 101d and the second limiting protrusion 10101 will not affect the display area of ​​the display module 20.

[0060] Specifically, the thickness of the limiting structure 10' can be four, five, six, seven, or other multiples of the thickness of the second limiting protrusion 10101.

[0061] To facilitate the insertion of the display module 20 into the limiting structure 10', please refer to [link / reference]. Figure 4 In one embodiment of this application, the diameter of the limiting structure 10' on the side away from the display area 10a is gradually reduced in the direction from the limiting structure 10' to the display area 10a. Specifically, the first limiting protrusion 101d is provided with a first inclined surface 1011d, which is located on the surface of the first limiting protrusion 101d away from the limiting wall 10d and away from the display area 10a. The second limiting protrusion 10101 is provided with a second inclined surface 10101a, which is located on the surface of the second limiting protrusion 10101 away from the limiting structure 10' and away from the display area 10a. Both the first inclined surface 1011d and the second inclined surface 10101a are inclined outward in the direction from the display area 10a to the limiting structure 10'. This arrangement allows the first inclined surface 1011d and the second inclined surface 10101a to play a guiding role when the display module 20 extends into the limiting structure 10'.

[0062] In other embodiments, the first inclined surface 1011d and the second inclined surface 10101a can also be replaced by an outwardly convex arc surface.

[0063] In order to utilize the structural characteristics of the fan housing 10 itself to form the first inner wall 10c and the limiting wall 10d, please refer to Figure 3 and Figure 4 In one embodiment of this application, the mounting cavity 10b is L-shaped and has a first segment 11b and a second segment 12b connected at an angle; the shape of the fan housing 10 is adapted to the shape of the mounting cavity 10b and is L-shaped, so that an L-shaped notch 10e is formed on the outside of the fan housing 10; the inner wall of the second segment 12b away from the first segment 11b is formed as a first inner wall 10c, and the inner wall of the second segment 12b near the notch 10e is formed as a limiting wall 10d. With this configuration, the first inner wall 10c and the limiting wall 10d can be formed by utilizing the structural characteristics that both the mounting cavity 10b and the fan housing 10 are L-shaped, thereby enabling the construction of the limiting structure 10' using the original structure of the fan housing 10.

[0064] Further, please refer to Figures 1 to 3 The portable fan 100 also includes a motor 40, foldable fan blades 50, and a battery 60. The motor 40 is located in the end of the first segment 11b away from the second segment 12b, and the output shaft of the motor 40 extends out of the fan housing 10 and is connected to the fan blades 50 located in the notch 10e. The battery 60 is located in the first segment 11b and on the side of the motor 40 facing the second segment 12b.

[0065] To protect the display module 20, please refer to [link / reference needed]. Figure 1 and Figure 2 In one embodiment of this application, the portable fan 100 further includes a cover 70, which is disposed on the outside of the fan housing 10 and covers the display area 10a.

[0066] Specifically, please refer to Figure 1 and Figure 2 The outer side of the fan housing 10 has a mounting groove 10f, and the display area 10a is located at the bottom of the mounting groove 10f. Both sides of the bottom wall of the mounting groove 10f in the length direction are provided with buckle holes 10g. The inner side of the cover 70 is provided with two buckles 701, and each buckle 701 cooperates with the corresponding buckle hole 10g, so that the cover 70 can be easily installed and removed.

[0067] And please see Figure 1 and Figure 2 The cover 70 is arc-shaped, with its concave side facing the display area 10a and its convex side flush with the outer surface of the fan housing 10. This design makes the cover 70 a convex mirror structure, which can magnify the display content of the display module 20, thereby making it easier for the user to observe the display content of the display module 20.

[0068] Please see Figures 5 to 7 In one embodiment of this application, the portable fan 100 further includes a storage housing 80, the fan housing 10 is movably connected to the storage housing 80, and the fan housing 10 has an idle state stored inside the storage housing 80 and a use state located outside the storage housing 80.

[0069] There are many ways in which the fan housing 10 and the storage housing 80 can be movably connected. In this embodiment, please refer to... Figures 5 to 7 The storage housing 80 has a storage groove 80a. The storage housing 80 is rotatably connected to the fan housing 10, and the rotation axis of the fan housing 10 is perpendicular to the rotation axis of the motor 40. This arrangement allows the fan housing 10 to be stored inside the storage housing 80 when idle, and to rotate out of the storage housing 80 when in use. In other embodiments, the storage housing 80 may also have a storage groove 80a, and the storage housing 80 may be rotatably connected to the fan housing 10, with the rotation axis of the fan housing 10 parallel to the rotation axis of the motor 40; alternatively, the storage housing 80 may be cylindrical, allowing the fan housing 10 to be pulled out of the storage housing 80.
