[0037] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0038] like Figure 1-8 As shown in the figure, the following embodiment discloses a portable clip-on fan.

[0039] Example 1

[0040] A portable, clip-on fan, comprising,

[0041] The fan body 100 has at least an air outlet surface 101 and an air inlet surface 102;

[0042] The clamping member 200 is hinged to the fan body 100 and has a driving side 210 and a clamping side 220 relative to the fan body 100; the driving side 210 can move relative to the fan body 100 so that the clamping side 220 has a closed state and an open state.

[0043] It also includes an elastic torsion member 300, which includes an integrally formed fixing section 310 and a torsion section 320. The fixing section 310 is disposed on the fan body 100 / clamping member 200, and the torsion section 320 acts on the clamping member 200 / fan body 100.

[0044] The plane containing the fixed segment 310 and the plane containing the torsion segment 320 are set at an angle.

[0045] The above is the basic scheme of this embodiment.

[0046] Specific reference Figure 1 As shown in Figure 2, in order to provide more convenient air outlet, in this embodiment, the upper end face of the fan body 100 is set as the air outlet face 101, the front end face is set as the air inlet face 102, and the clamping member 200 is set on the back of the fan body 100 opposite to the air inlet face 102.

[0047] The drive side 210 of the clamp 200 is hinged to the fan body 100. When the user applies force to the drive side 210, the clamp 200 can rotate around the hinge axis, thereby moving the clamp side 220 away from the back of the fan body 100 and opening it so that the fan body 100 can be held on clothing. The clamping method is the same as that of the clamping fan in the prior art, and will not be described in detail here.

[0048] When force is applied to the drive side 210 to open the clamp 200, the torsion section 320 of the elastic torsion member 300 deforms and torsional, generating a torsion force. When the external force on the connection side is removed, the elastic torsion member 300 returns to its original position, and the torsion section 320 drives the fan body 100 or the clamp 200 that abuts against it to return to the closed state or clamps the clothing between the clamping side 220 and the fan body 100.

[0049] In this embodiment, it is preferable to place the fixed section 310 on the fan body 100, place the torsion section 320 on the clamping member 200, and place the torsion section 320 against the drive side 210 of the clamping member 200.

[0050] Preferably, in this embodiment, the elastic torsion member 300 is a torsion spring.

[0051] Specific reference Figure 2 and Figure 3 As shown, the drive side 210 needs to maintain a certain distance from the fan body 100 so that when the clamp 200 is opened, the drive side 210 can be pressed toward the fan body 100 so that the clamp side 220 can move toward the side away from the fan body 100.

[0052] Under these conditions, a distance needs to be maintained between the torsion section 320 and the fan body 100. Therefore, in this embodiment, the plane where the fixed section 310 is located and the plane where the torsion section 320 is located are set at an angle, so that at least the part of the torsion section 320 that abuts against the clamping member 200 has a certain distance from the fixed section 310.

[0053] Preferably, in this embodiment, the fixed segment 310 is an L-shaped segment and the torsion segment 320 is a U-shaped segment.

[0054] Specific reference Figure 3 As shown, the fixing section 310 includes a short rod 311 and a long rod 312. The short rod 311 is inserted into the fan body 100, thereby fixing the fixing section 310 as a whole to the fan body 100. The torsion section 320 is connected to the end of the long rod 312, and the U-shaped structure and the short rod 311 are not on the same plane.

[0055] In this embodiment, to ensure torsional force, one straight edge of the U-shaped structure is aligned with the long rod 312 of the fixed section 310. In this way, when torsional force occurs in the torsion section 320, the long rod 312 will also generate a small amount of torsional force accordingly. Moreover, the further away from the torsion section 320, the less torsion occurs. This decomposes the torsional force on the fixed section 310, avoiding the situation where the torque at the connection between the fixed section 310 and the torsion section 320 is too large and causes breakage.

[0056] In this embodiment, during assembly, the short rod 311 of the fixing section 310 is inserted into the fan body 100 at an angle perpendicular to the back of the fan body 100, so that the torsion section 320 forms an angle with the back of the fan body 100. That is, the straight rod on the U-shaped section that is not connected to the long rod 312 is raised relative to the fan body 100, so that it can abut against the end face of the clamping member 200.

[0057] When the torsion section 320 is torsion relative to the fixed section 310 under the action of the clamping member 200, the long rod 312 of the fixed section 310 will also have a small amount of torsion under the action of the torsion section 320. In order to avoid displacement under this torsion force, in this embodiment, the back of the fan body 100 is provided with a mounting groove 111 that can be fixed with the fixed section 310. The torsion section 320 extends out of the mounting groove 111 and abuts against the connecting side of the clamping member 200.

[0058] Specific reference Figure 5 As shown, a fixing hole 112 is provided at the bottom of one end of the mounting groove 111, which allows the short rod 311 of the fixing section 310 to be inserted into the fixing hole 112, and the torsion section 320 to be exposed outside the mounting groove 111.

[0059] When the clamp 200 is opened, the drive side 210 moves closer to the fan body 100, that is, the torsion section 320 that abuts against it moves closer to the plane where the fixed section 310 is located. In order to avoid interference between the slot of the mounting groove 111 and the torsion section 320, in this embodiment, the mounting groove 111 is provided with a notch 113.

[0060] Specific reference Figure 5 As shown, the position of the notch 113 is consistent with the position of the torsion section 320, and it can accommodate the insertion of the torsion section 320.

[0061] When the clamping member 200 is opened to its maximum angle, the twisting section 320 enters the notch 113.

[0062] Meanwhile, in order to ensure that the position of the torsion segment 320 is constant under the action of torsion force, in this embodiment, the clamping member 200 is provided with a receiving groove 201 that can restrict the torsion segment 320.

[0063] Specific reference Figure 5 As shown, the receiving groove 201 can at least accommodate the outer straight section of the U-shape of the torsion section 320 to ensure the abutment relationship between the torsion section 320 and the clamping member 200.

[0064] In addition, in this embodiment, the back of the fan body 100 is provided with a hinge protrusion 110, and the hinge protrusion 110 and the clamping member 200 are connected by a hinge shaft.

[0065] The mounting groove 111 is provided on the hinge protrusion 110.

[0066] Specific reference Figure 4As shown, the hinge protrusion 110 is a strip-shaped protrusion protruding on the back of the fan body 100. The two ends of the hinge protrusion 110 are provided with hinge holes 114. The hinge shaft is provided in the hinge holes 114. The driving side 210 and the clamping side 220 are respectively provided on both sides of the hinge holes 114.

[0067] Furthermore, in this embodiment, a receiving groove 201 is formed on the end face of the clamping member 200 by short ribs, and the receiving groove 201 can completely accommodate the hinge protrusion 110.

[0068] At the same time, the short ribs can contact the outer shell body, ensuring that there is still a gap between the clamping part 200 and the outer shell body in the closed state.

[0069] Preferably, in this embodiment, the short ribs that form the receiving groove 201 include a clearance side rib position 232, an abutment side rib position 231, and a wedge-shaped side rib position 233 connecting the clearance side rib position 232 and the abutment side rib position 231. The inclined surface of the wedge-shaped side rib position 233 is located on the driving side 210, the clearance side rib position 232 and the abutment side rib position 231 are located on the driving side 210 and the clamping side 220, respectively, and the height of the clearance side rib position 232 is lower than the height of the abutment side rib position 231.

[0070] The hinge shaft is connected to the wedge-shaped side rib position 233.

[0071] When the clamp 200 is opened, the drive side 210 rotates toward the fan body 100, and the height of the clearance side rib 232 is low so as not to interfere with the drive side 210; when the clamp 200 is closed, the inner end face of the clamping side 220 of the clamp 200 abuts against the rib on the contact side, that is, it is reset to the set position.

[0072] In addition, in this embodiment, the clamping member 200 and / or the fan body 100 are provided with a clamping rib 1.

[0073] Preferably, in this embodiment, clamping ribs 1 are provided on the back of both the clamping member 200 and the fan body 100, and the two clamping ribs 1 are staggered.

[0074] Specific reference Figure 6 As shown, when the clamping member 200 is in the closed state, the two clamping ribs 1 abut against the back of the fan body 100 and the clamping member 200 respectively, making the clamping member 200 parallel to the back of the fan body 100, thus increasing its aesthetics.

[0075] Example 2

[0076] This embodiment is an improvement on Embodiment 1, and its purpose is to provide another form of the elastic torsion member 300. The specific implementation method is as follows:

[0077] Both the fixed section 310 and the torsion section 320 are U-shaped sections.

[0078] Specific reference Figure 7 As shown, in this embodiment, there are two torsion segments 320, which are symmetrically arranged at both ends of the fixed segment 310. In order to ensure that the torsional force of the two torsion segments 320 is consistent, the two torsion segments 320 in this embodiment are on the same plane and form an angle with the plane where the fixed segment 310 is located.

[0079] In order to cooperate with the elastic torsion member 300, in this embodiment, the middle of the mounting groove 111 is set as a deep groove, which can insert and fix the U-shaped bottom of the fixing section 310. The two sides of the mounting groove 111 are provided with notches 113 that are consistent with the torsion section 320, as detailed in the following figure. Figure 8 As shown.

[0080] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
