[0035] The technical solutions of the embodiments of the present invention are explained and described below in conjunction with the drawings of the embodiments of the present invention, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0036] Ginseng Figures 1 to 9 As shown, a fan is disclosed, and its handle assembly mechanism includes a housing 10, a handle connector 3 fixed to the housing 10, a handle 11 that can be detachably assembled with the handle connector 3 to be detachably assembled to the outside of the housing 10, a first screw 13, and a second screw 12. The handle connector 3 is provided with a warping edge that is snap-fitted with the handle 11, and the warping edge includes a first warping edge 30 and a second warping edge 31 that are snap-fitted with the handle 11, and at least a portion of the first warping edge 30 and at least a portion of the second warping edge 31 are located on opposite sides of the handle connector 3. With the help of the first warping edge 30 and the second warping edge 31, the handle connector 3 can be snap-fitted with the handle 11 more reliably and evenly, which is also conducive to the quick screw locking between the handle 11 and the handle connector 3. The first warping edge 30 and the second warping edge 31 are located on the outside of the housing 10. The housing 10 is cylindrical.

[0037] The handle 11 is provided with a folded edge for snapping with the warping edge, and the folded edge includes a first folded edge 400 for snapping with the first warping edge 30, and a second folded edge 401 for snapping with the second warping edge 31. The first folded edge 400 constitutes an example of a first protrusion, and the second folded edge 401 constitutes an example of a first protrusion. The first protrusion at least partially enters between the first warping edge 30 and the shell 10, and the second protrusion at least partially enters between the second warping edge 31 and the shell 10. The folded edge and the warping edge can be snapped together more fully, thereby improving the reliability of the snap fit. The first folded edge 400 and the second folded edge 401 are close to the outer surface of the shell 10. The first warping edge 30, the second warping edge 31, the first folded edge 400, and the second folded edge 401 are correspondingly provided with a first guide surface 300, a second guide surface 310, a third guide surface 4000, and a fourth guide surface 4010 for guiding the warping edge and the folded edge to snap together.

[0038] The handle 11 includes a mounting port portion 40 facing the housing 10, the handle connector 3 includes a bottom plate 32, the bottom plate 32 is accommodated in the mounting port portion 40, the first folded edge 400 and the second folded edge 401 are arranged on opposite sides of the mounting port portion 40, the first folded edge 400 and the second folded edge 401 extend toward each other, and the bottom plate 32 is located between the first folded edge 400 and the second folded edge 401. The first folded edge 400, the second folded edge 401 and the bottom plate 32 are substantially coplanar.

[0039] The mounting port 40 is further provided with a first connecting fold 402 and a second connecting fold 403, the first connecting fold 402 and the second connecting fold 403 are provided on opposite sides of the mounting port 40, the first connecting fold 402 and the second connecting fold 403 extend toward each other, one end of the first connecting fold 402 is integrally connected with one end of the first fold 400, the other opposite end of the first connecting fold 402 is integrally connected with one end of the second fold 401, one end of the second connecting fold 403 is integrally connected with the other opposite end of the first fold 400, and the other opposite end of the second connecting fold 403 is integrally connected with the other opposite end of the second fold 401. Such a design enhances the stability of the first fold 400 and the second fold 401.

[0040] The first folded edge 400, the second folded edge 401, the first warped edge 30, and the second warped edge 31 are respectively in the shape of long strips, and the first folded edge 400 and the first warped edge 30 are placed side by side, and the second folded edge 401 and the second warped edge 31 are placed side by side. Thus, the stability of the snap fit between the folded edge and the warped edge is enhanced. One of the first folded edge 400 and the first warped edge 30 is provided with an anti-foolproof notch 4001, and the other of the first folded edge 400 and the first warped edge 30 is provided with an anti-foolproof protrusion 301 embedded in the anti-foolproof notch 4001. In this embodiment, the anti-foolproof notch 4001 is provided on the first folded edge 400, and the anti-foolproof protrusion 301 is provided on the first warped edge 30.

[0041] The first warped edge 30 and the second warped edge 31 are located on opposite sides of the handle connector 3, and the bottom plate 32 is abutted against the outer surface of the shell 10. The first warped edge 30 and the second warped edge 31 are respectively and integrally connected to the bottom plate 32. The first warped edge 30 is warped from one side of the bottom plate 32 toward a direction away from the outer surface of the shell 10, and the second warped edge 31 is warped from the opposite side of the bottom plate 32 toward a direction away from the outer surface of the shell 10.

[0042] The handle connecting member 3 further includes a bracket 33 extending from the bottom plate 32 in a direction away from the outer surface of the housing 10. The second screw 12 is used to lock the bracket 33 and the handle 11 together. The second screw 12 crosses the bracket 33 so that the bracket 33 and the handle 11 are locked together. The first screw 13 is used to lock the handle connecting member 3 to the housing 10. The housing 10 is provided with a first through hole 100. The first screw 13 partially penetrates the first through hole 100, the bottom plate 32, and the bracket 33. The screw seat 130 of the first screw 13 is located outside the first through hole 100. The first screw 13 is screwed to the bracket 33. The handle connecting member 3 is also provided with a screw hole 34 for the first screw 13 to be screwed. The screw hole 34 extends from the bottom plate 32 to the inside of the bracket 33.

[0043] The housing 10 is further provided with a second through hole 101, and the bottom plate 32 is extended with a positioning protrusion 320 extending into the second through hole 101, and the positioning protrusion 320 and the bracket 33 are located on opposite sides of the bottom plate 32. The first screw 13 and the positioning protrusion 320 enable the handle connecting member 3 to be firmly held on the housing 10. In this embodiment, there are two handle connecting members 3, and the spacing between the first through hole 100 and the second through hole 101 corresponding to one handle connecting member 3 is not equal to the spacing between the first through hole 100 and the second through hole 101 corresponding to the other handle connecting member 3, so that the handle connecting member 3 is difficult to be assembled on the first through hole 100 and the second through hole 101 that do not correspond to it, so as to achieve foolproofing.

[0044] The handle 11 includes a first screw column 112 and a second screw column 113 extending toward each other for locking the second screw 12. The first screw column 112 and the second screw column 113 are located on opposite sides of the bracket 33. The second screw 12 can be inserted into the second screw column 113, the bracket 33, and the first screw column 112 in sequence from the outside of the handle 11. Therefore, the locking operation of the second screw 12 is easy, which is convenient for the user to lock the handle 11 to the bracket 33 through the second screw 12. The user can directly snap the handle 11 and the warped edge together and then lock the second screw 12. The first screw column 112 and the second screw column 113 clamp the bracket 33; during assembly, the warped edge and the handle 11 are snapped together, and the bracket 33 is inserted into the predetermined position between the first screw column 112 and the second screw column 113. The reason for the clamping is that the locking of the second screw 12 causes the distance between the first screw column 112 and the second screw column 113 to be shortened by the second screw 12, thereby clamping the bracket 33. Specifically, the first screw column 112 and the second screw column 113 clamp the main body 330 of the bracket 33. The first warping edge 30 and the first screw column 112 are located on one side of the bracket 33, and the second warping edge 31 and the second screw column 113 are located on the other side of the bracket 33. With this design, the handle 11 and the handle connector 3 are more balanced and not easily deviated.

[0045] The main body 330 extends from the bottom plate 32 in a direction away from the outer surface of the shell 10. The bracket 33 is also provided with a first connecting plate 331 and a second connecting plate 332 located on opposite sides of the main body 330. The first connecting plate 331 connects the main body 330 and the first warped edge 30, and the second connecting plate 332 connects the main body 330 and the second warped edge 31. The first warped edge 30, the main body 330, and the second warped edge 31 are arranged in parallel, and the first screw column 112 and the second screw column 113 are located on opposite sides of the bracket 33. The bottom edges of the first connecting plate 331 and the second connecting plate 332 are connected to the bottom plate 32, the screw hole 34 extends from the bottom plate 32 into the main body 330, the first screw 13 partially penetrates the first through hole 100, the bottom plate 32, and the main body 330, and the first screw 13 is screwed to the main body 330; after the handle 11 and the handle connector 3 are assembled together, the second screw 12 passes through the main body 330 and the first screw column 112 and the second screw column 113 clamp the main body 330 towards each other.

[0046] The main body 330 is provided with a first extension 333 connected to the bottom plate 32 at one end, a second extension 334 connected to the bottom plate 32 at one end, and an undercut protrusion 335. The second screw 12 penetrates and is screwed to the first screw column 112. The screw seat 120 of the second screw 12 is located in the second screw column 113. The edge 336 of the other end opposite to the first extension 333, the edge 337 of the other end opposite to the second extension 334, and the undercut protrusion 335 surround the free end 114 of the first screw column 112. The second screw 12 is located between the undercut protrusion 335 and the bottom plate 32. Thus, the position of the free end 114 of the first screw column 112 is preliminarily limited within a certain range, and no large deviation occurs, which facilitates the subsequent locking of the second screw 12 to proceed smoothly. During the process of the bracket 33 being inserted between the first screw column 112 and the second screw column 113, the free end 114 of the first screw column 112 interferes with the undercut protrusion 335 (i.e., the free end 114 of the first screw column 112 interferes with the undercut protrusion 335 when passing through it), and the undercut protrusion 335 inhibits the first screw column 112 from reversing after entering the predetermined position. The main body 330 is also provided with a through slot 338, and the second screw 12 passes through the main body 330 through the through slot 338. The second screw column 113 is perpendicular to the length direction of the first warping edge 30 and the length direction of the second warping edge 31. The main body 330 is perpendicular to the bottom plate 32.

[0047] The handle 11 includes a handle 110, an arm 111 connected to the handle 110 at one end, a mounting port 40 is provided at the other end of the arm 111, and the bracket 33 can be inserted into the arm 111 through the mounting port 40. The handle 11 can be assembled to and detached from the handle connector 3 as a whole. In this embodiment, the handle 11 is formed by locking a first half handle 115 and a second half handle 116 together through a plurality of third screws 117. The first screw column 112 is provided on the first half handle 115, and the second screw column 113 is provided on the second half handle 116.

[0048] The handle assembly mechanism is not limited to fans, but can also be applied to other devices, such as vacuum cleaners, etc. Therefore, the housing 10 can also be the housing of other devices such as vacuum cleaners.

[0049] In addition, the present application also provides a fan kit, including a packaging box (not shown, such as a common rectangular packaging box), the outer shell 10 is a part of the fan body 2, the fan body 2 also includes a fan blade 17, a front mesh cover 15 and a rear mesh cover 16 arranged on opposite sides of the outer shell 10, and the outer shell 10 surrounds the fan blade 17. In the packaging box: the handle 11 is not assembled with the handle connector 3 and the handle connector 3 is assembled and fixed to the outer shell 10. With such a design, the user can assemble the handle by himself after getting the product, which is conducive to reducing the packaging difficulty of the manufacturer, the volume of the fan kit, reducing costs, and improving transportation efficiency. The fan also includes a fan base 18, and the fan base 18 can be installed on the fan body 2 to support the fan body 2. The fan base 18 is not assembled with the fan body 2 in the packaging box to reduce the packaging volume. During installation, the fan base 18 is installed on the outer shell 10 of the fan body 2 through the knob member 19.
