Detailed Implementation

[0025] 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.

[0026] 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.

[0027] This application provides an accessory for a portable fan, which integrates the pad and the plug into one piece, thus achieving the integrated setting of the pad and the plug. This allows the accessory to have both the stable support function of the pad and the function of the plug to seal or open the liquid inlet. In this way, it can effectively avoid the problem of reduced stability of portable fans when placed due to the plug protruding from the placement surface of the portable fan in the prior art. In other words, it can ensure the stability of the portable fan when placed while setting the plug.

[0028] 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.

[0029] Please see Figure 1 and Figure 2 This application provides a portable fan accessory 100, which includes a pad 110 and a plug 120. The pad 110 and the plug 120 are integrally formed. The pad 110 is used to be installed on the placement surface 201 of the fan body 200 of the portable fan 1000, and the plug 120 is used to block or open the liquid injection port 202 on the placement surface 201 of the portable fan 1000.

[0030] Both the pad 110 and the plug 120 can have various shapes, including square, round, oval, rhomboid, and other regular shapes, as well as other irregular shapes; no specific limitation is made here. Obviously, the shape of the plug 120 is adapted to the shape of the injection port 202.

[0031] There are many ways to integrally form the pad 110 and the plug 120. The pad 110 and the plug 120 can be formed by injection molding, stamping, or other integral forming methods such as 3D printing. No specific limitation is made here.

[0032] It is worth mentioning that the integral molding of the pad 110 and the plug 120 not only enables the integrated arrangement of the pad 110 and the plug 120, but also enhances the connection strength between the pad 110 and the plug 120. In other embodiments, the pad 110 and the plug 120 may also be configured as two separate components, which are fixed together by a fixed connection or a detachable connection method described below.

[0033] Both the pad 110 and the plug 120 are made of elastic materials such as silicone, rubber, silicone rubber, and plastic. This design serves two purposes: firstly, it increases the friction experienced by the pad 110 during placement, improving the stability of the portable fan 1000 and cushioning the impact forces experienced by the portable fan 1000 during placement; secondly, it ensures the seal of the plug 120 when sealing the injection port 202. Obviously, the materials of the pad 110 and the plug 120 can be the same or different; no specific limitation is made here.

[0034] There are many possible correspondences between the pad 110 and the plug 120. The pad 110 and the plug 120 can be configured in a one-to-one manner: one pad 110 and one plug 120 are integrally formed. Figure 1The illustration shows a one-to-one arrangement of pad 110 and plug 120; pad 110 and plug 120 can also be arranged in a one-to-many manner: one pad 110 and multiple plugs 120 are integrally formed (multiple in this article refers to at least two). Correspondingly, the placement surface 201 of the portable fan 1000 is provided with multiple liquid injection ports 202, and each plug 120 is used to block the corresponding liquid injection port 202, which is not specifically limited here.

[0035] There are many ways to connect the pad 110 and the placement surface 201. The pad 110 and the placement surface 201 can be connected by a fixed connection such as adhesive or ultrasonic welding, or they can be connected by a detachable connection such as snap-fit, snap-on, magnetic connection, or Velcro lettering. No specific limitation is made here.

[0036] Through the above technical solution, by integrally molding the pad 110 and the plug 120, the integrated setting of the pad 110 and the plug 120 is realized. This allows the accessory 100 of the portable fan to have both the stable support function of the pad 110 and the function of sealing or opening the liquid injection port 202 of the plug 120. This effectively avoids the problem of reduced stability of the portable fan when placed due to the plug 120 protruding from the placement surface 201 of the portable fan 1000 in the prior art. In other words, the stability of the portable fan 1000 can be guaranteed when placed while setting the plug 120.

[0037] For easier integration of the plug 120 into the pad 110, please refer to Figure 1 and Figure 3 In one embodiment of this application, the pad 110 partially extends to form a relief opening 1101, and the plug 120 is partially located inside the relief opening 1101. The plug 120 is connected to the inner wall of the relief opening 1101. This arrangement can reduce the size of the portable fan accessory 100 and facilitate the integrated design of the plug 120 and the pad 110.

[0038] Specifically, the portion of the plug 120 located within the relief opening 1101 is connected to an inner wall of the relief opening 1101 in the longitudinal direction, thus facilitating the integral molding of the pad 110 and the plug 120. In other embodiments, the plug 120 may also be connected to an inner wall of the relief opening 1101 in the width direction, or the plug 120 may be connected to both an inner wall of the relief opening 1101 in the longitudinal direction and an inner wall of the relief opening 1101 in the width direction.

[0039] It should be noted that when there are multiple plugs 120, there can be one clearance opening 1101, with multiple plugs 120 located in the same clearance opening 1101. Alternatively, there can be multiple clearance openings 1101, with each plug 120 located in its corresponding clearance opening 1101. Of course, the number of plugs 120 corresponding to each clearance opening 1101 can also be different, and no specific limitation is made here.

[0040] In other embodiments, the edge of the pad 110 may be partially through to form a clearance notch, and the plug 120 may be partially located within the clearance notch and connected to the inner wall of the clearance notch; or the plug 120 may be a separately set structural component installed in the clearance opening 1101. In this case, the installation method of the plug 120 may be set in accordance with the fixed connection or detachable connection method in the above embodiments, which will not be described in detail here.

[0041] There are many types of the plug 120 mentioned above; please refer to [link / reference]. Figure 1 In one embodiment of this application, the plug 120 includes an operating part 121 and a sealing part 122. The operating part 121 has a connecting end 1211 and an operating end 1212 disposed opposite to each other. The connecting end 1211 is connected to the pad 110. The sealing part 122 is disposed on the inner side 1102 of the operating part 121 and is used to seal or open the injection port 202.

[0042] Specifically, the two sides of the operating part 121 in the length direction are respectively formed as a connecting end 1211 and an operating end 1212. The connecting end 1211 of the operating part 121 is connected to an inner wall of the clearance opening 1101 in the length direction, and the operating end 1212 of the operating part 121 is a free end and is not constrained. Obviously, the two sides of the operating part 121 in the width direction are respectively spaced apart from the two inner walls in the width direction of the clearance opening 1101, so as to apply a corresponding operating force to the operating end 1212.

[0043] Further, please refer to Figure 1 The side of the operating part 121 connected to the sealing part 122 is provided with a clearance groove 12101 extending along its width direction. The clearance channel is located at the connecting end 1211 of the operating part 121. This arrangement facilitates the elastic deformation of the connecting end 1211 under external force. In other words, it facilitates the elastic deformation of the connection position between the operating part 121 and the pad 110 under external force, thereby making it easier to bend the operating part 121.

[0044] With the above technical solution, when sealing the injection port 202, press the operating end 1212 of the operating part 121 in the direction close to the injection port 202 until the sealing part 122 cooperates with the injection port 202 to seal the injection port 202; when opening the injection port 202, pry the operating end 1212 of the operating part 121 in the direction away from the injection port 202 until the sealing part 122 disengages from the injection port 202 to open the injection port 202.

[0045] In other embodiments, the plug 120 may also be configured to include only the sealing portion 122, which is directly integrally formed on the inner side 1102 of the pad 110.

[0046] There are many types of the aforementioned sealing part 122; please refer to [link / reference]. Figure 1 , Figure 4 as well as Figure 5 In one embodiment of this application, the blocking part 122 includes a first segment 1221 and a second segment 1222. The second segment 1222 is connected to the first segment 1221. The side of the first segment 1221 away from the second segment 1222 is connected to the inner side 1102 of the operating part 121. The outer diameter of the second segment 1222 is larger than the outer diameter of the first segment 1221.

[0047] Specifically, when sealing the injection port 202, the outer peripheral wall of the first segment 1221 mates with the inner peripheral wall of the injection port 202, thereby enhancing the sealing performance of the sealing part 122 when sealing the injection port 202. Alternatively, the inner peripheral wall of the first segment 1221 and the inner peripheral wall of the injection port 202 can have a small interference fit, which further enhances the sealing performance of the sealing part 122 at the fan injection port 202 while not interfering with the assembly and disassembly of the first segment 1221. In other embodiments, when sealing the injection port 202, the outer peripheral wall of the first segment 1221 may also have a gap between it and the inner peripheral wall of the injection port 202.

[0048] With the above technical solution, when sealing the injection port 202, press the operating end 1212 of the operating part 121 in the direction close to the injection port 202, so that the second segment 1222 is squeezed by the inner wall of the injection port 202 and undergoes elastic deformation until the second segment 1222 passes through the injection port 202 and is upside down inside the portable fan 1000 adjacent to the inner wall of the injection port 202, and the first segment 1221 is located inside the injection port 202, thus sealing the injection port 202; when opening the injection port 202, pry the operating end 1212 of the operating part 121 in the direction away from the injection port 202, so that the second segment 1222 is squeezed by the inner wall of the injection port 202 and undergoes elastic deformation until the first segment 1221 and the second segment 1222 are successively disengaged from the injection port 202, thus opening the injection port 202. This setting can ensure the sealing performance of the sealing part 122 when sealing the injection port 202.

[0049] In other embodiments, the sealing part 122 may also be configured to include only the first segment 1221; the sealing part 122 may also be configured as a plunger, the outer peripheral wall of the plunger is provided with a sealing ring extending along its circumference, and correspondingly, the inner peripheral wall of the injection port 202 is provided with a sealing groove extending along its circumference, the plunger cooperates with the injection port 202, and the sealing ring cooperates with the sealing groove.

[0050] To facilitate pressing the second segment 1222 into the portable fan 1000 through the injection port 202, please refer to [link / reference needed]. Figure 1 In one embodiment of this application, the outer diameter of the second segment 1222 gradually narrows from the direction close to the first segment 1221 to the direction away from the first segment 1221. This configuration makes the outer peripheral wall of the second segment 1222 form an inclined guide surface. The guide surface can guide the second segment 1222 when it is squeezed by the inner wall of the injection port 202, thereby making it convenient for the second segment 1222 to be pressed into the portable fan 1000 through the injection port 202.

[0051] In this embodiment, please refer to Figure 1 The second segment 1222 is shaped like a frustum. This design allows the outer peripheral wall of the second segment 1222 to form an inclined guide surface, and also shortens the axial length of the second segment 1222, thereby reducing the size of the portable fan accessory 100. In other embodiments, the second segment 1222 can also be shaped like a cone. This design also allows the outer peripheral wall of the second segment 1222 to form an inclined guide surface.

[0052] To facilitate applying operating force to the operating end 1212 and removing the sealing part 122 through the injection port 202, please refer to... Figure 1 as well as Figures 3 to 5 In one embodiment of this application, the operating end 1212 is tilted upwards toward the operating part 121 away from the blocking part 122. This arrangement makes the operating end 1212 tilted upwards, thereby making it convenient for the user to apply operating force to the operating end 1212 through tools or the cooperation of multiple fingers.

[0053] The angle at which the operating end 1212 is tilted toward the operating part 121 away from the sealing part 122 can be 1 degree, 2 degrees, 3 degrees, 4 degrees, 5 degrees, 6 degrees, 7 degrees, 8 degrees, 9 degrees, 10 degrees, or other angle values, and no specific limitation is made here.

[0054] Furthermore, the operating end 1212 is stepped on the side facing the blocking part 122, so that the thickness of the operating end 1212 is less than the thickness of the other parts of the operating part 121, which makes it easier for the user to hold the operating end 1212 with tools or multiple fingers.

[0055] In other embodiments, while the operating end 1212 is tilted up, a through-hole can also be provided on the operating end 1212, so that the user can hold the operating end 1212 by passing his finger through the through-hole.

[0056] Please see Figure 1 In one embodiment of this application, both the pad 110 and the operating part 121 extend along the direction from the air inlet to the air outlet of the portable fan 1000. This arrangement reduces the size of the pad 110 and the operating part 121 in the direction perpendicular to the air blowing direction of the portable fan 1000. Correspondingly, it reduces the thickness of the portable fan 1000 in the direction perpendicular to its air blowing direction, making it easier for the user to hold the portable fan 1000.

[0057] Considering that when adding liquid with the portable fan 1000's placement surface 201 facing upwards and its liquid inlet 202 positioned at the top, if liquid accidentally overflows from the liquid inlet 202, the overflowing liquid will flow down the outer surface of the portable fan 1000, affecting the user experience, please refer to [the relevant regulations / guidelines]. Figure 1 and Figure 3 In one embodiment of this application, the pad 110 has an inner side 1102 and an outer side 1103 that are arranged opposite to each other. The outer side 1103 is provided with a groove 1104. The inner peripheral wall of the groove 1104 surrounds the plug 120. This arrangement allows the overflowing liquid to be located in the groove 1104 and not to flow down the outer surface of the portable fan 1000, thereby improving the user experience.

[0058] Specifically, the operating end 1212 is tilted upwards toward the operating part 121 away from the sealing part 122 and is located in the groove 1104. This arrangement ensures that the tilting of the operating end 1212 will not interfere with the placement of the pad 110.

[0059] Please see Figure 1 , Figure 2 as well as Figure 5 This application embodiment also provides a portable fan 1000, which includes the portable fan accessory 100 and the fan body 200 as described above. The fan body 200 has a placement surface 201 and an injection port 202. The injection port 202 is disposed on the placement surface 201. A pad 110 is installed on the placement surface 201. A plug 120 blocks or opens the injection port 202.

[0060] By way of example and not limitation, the portable fan 1000 can be any of the following: a fan with a handle, a folding fan, a sliding fan, and a telescopic fan.

[0061] In this embodiment, the placement surface 201 of the fan body 200 is the bottom surface of the fan body 200. Obviously, in other embodiments, the placement surface 201 of the fan body 200 can also be set as the top surface of the fan body 200, the side surface of the fan body 200, or other positions of the fan body 200.

[0062] It is worth mentioning that the portable fan 1000 and its accessories 100 can be set up one-to-one or one-to-many. In this case, the placement surface 201 of the portable fan 1000 is formed into multiple placement areas, each placement area is provided with a liquid inlet 202, and each portable fan accessory 100 is placed in the corresponding placement area.

[0063] The specific structure of the accessory 100 of the portable fan 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.

[0064] Please see Figure 1 and Figure 2 In one embodiment of this application, the placement surface 201 is provided with a mounting groove 203, and the liquid injection port 202 is located at the bottom of the mounting groove 203. The pad 110 cooperates with the mounting groove 203. This arrangement makes it convenient to install the pad 110 onto the placement surface 201 of the portable fan 1000.

[0065] 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.
