[0038] See also Figure 1-Figure 3 In one embodiment of the present invention, a connection structure 100 is provided. The connection structure 100 is used to match various components of a floor-standing fan and a table-top fan to facilitate assembly and disassembly of the fan.

[0039] The connection structure 100 includes a first connection member 10 and a second connection member 50. The first connection member 10 includes a first body 12 and a first elastic member 14. The first connection member 10 is provided with a mounting hole 121 and a through slot 123 connected to the mounting hole 121. One end of the first elastic member 14 is connected to the inner wall of one side of the through slot 123. A gap is reserved between the other end of the first elastic member 14 and the inner wall of the other side of the through slot 123, so that the first elastic member 14 is allowed to elastically deform in the through slot 123. The first elastic member 14 is arranged in the through slot 123 and will not protrude from the first body 12, so that the outer surface of the connection structure 100 is relatively neat. The second connection member 50 includes a second body 52 and a second elastic member 54. The second elastic member 54 is arranged on the second body 52, the second elastic member 54 is sleeved in the mounting hole 121, and the second elastic member 54 is detachably buckled with the first elastic member 14.

[0040] When installing the connection structure 100, it is only necessary to insert the second elastic member 54 into the mounting hole 121 of the first body 12, so that the second elastic member 54 is buckled with the first elastic member 14, and the first connection member 10 and the second connection member 50 can be matched. In this way, the first connection member 10 and the second connection member 50 are conveniently assembled, and the assembly efficiency is improved. Similarly, when it is necessary to disassemble the first connection member 10 and the second connection member 50, the first elastic member 14 is pressed inwardly in the direction close to the mounting hole 121, so that the first elastic member 14 and the second elastic member 54 are deformed, so that the buckle between the first elastic member 14 and the second elastic member 54 is loosened, and finally the loosened first connection member 10 and the second connection member 50 are separated by external force, so that the disassembly method is simplified, and the connection structure 100 is easy to assemble and disassemble, thereby improving the assembly efficiency. It can be understood that the connection structure 100 is applied to the fan, and is used to assemble the base, rod body and fan body and other structures in the fan, so that the fan can be easily assembled and disassembled.

[0041] See also Figure 4Further, the first elastic member 14 includes a first connecting end 141 and a first free end 143 connected to each other, the first connecting end 141 is connected to the inner wall of the through groove 123, and the first free end 143 is suspended in the through groove 123; the second elastic member 54 includes a second connecting end 541 and a second free end 543 connected to each other, the second connecting end 541 is connected to the second body 52, and the second free end 543 is suspended; wherein, the first connecting end 141 is sleeved and connected to the outside of the second connecting end 541, the first free end 143 is sleeved and abutted against the outside of the second free end 543, and the first free end 143 and the second free end 543 are detachably buckled. That is to say, the first free end 143 and the second free end 543 of the first elastic member 14 and the second elastic member 54 are overlapped, so that when the first free end 143 is pressed in the direction toward the mounting hole 121, the second free end 543 can be easily deformed, thereby conveniently loosening the fastening of the first free end 143 and the second free end 543.

[0042] See also Figure 3-Figure 6 In some embodiments, a protrusion 145 facing the other is provided on one of the first free end 143 and the second free end 543, and a groove 545 is provided on the other of the first free end 143 and the second free end 543; wherein the protrusion 145 is accommodated in the groove 545, and the side of the protrusion 145 facing away from the first connection end 141 abuts against the inner wall of the side of the groove 545 facing away from the second connection end 541, so that the protrusion 145 abuts against the inner wall of the groove 545 in the direction from the first connection end 141 to the first free end 143, so as to detachably buckle the first elastic member 14 and the second elastic member 54 together.

[0043] Furthermore, the first body 12 abuts against the second body 52 on one side close to the first connecting end 141, that is, the first body 12 and the second body 52 abut against each other in the direction from the first free end 143 to the first connecting end 141, and the protrusion 145 and the inner wall of the groove 545 abut against each other in the direction from the first connecting end 141 to the first free end 143. In this way, the first elastic member 14 and the second elastic member 54 are limited in both the front and rear directions in which the first elastic member 14 and the second elastic member 54 are mutually sleeved, so as to prevent the first elastic member 14 and the second elastic member 54 from detaching from each other.

[0044] Furthermore, a disassembly gap 30 is reserved between the side of the protrusion 145 facing the first connection end 141 and the inner wall of the side of the groove 545 facing the second connection end 541. In this way, when the first elastic member 14 is bent inwardly by an external force, the protrusion 145 can move in the groove 545 toward the direction of the disassembly gap 30, and then the protrusion 145 can be separated from the inner wall of the side of the groove 545 facing away from the second connection end 541, and finally the second rod body is rotated along the circumference of the second rod body, so that the protrusion 145 and the groove 545 can be completely separated, thereby realizing the disassembly of the first connecting member 10 and the second connecting member 50.

[0045] Optionally, the side of the protrusion 145 facing the first connection end 141 is configured as an inclined surface 40; in a direction parallel to the direction in which the first connection end 141 points to the first free end 143, the inclined surface 40 is arranged to be inclined toward the second elastic member 54. The side of the protrusion 145 facing the first connection end 141 is also the side of the protrusion 145 facing the disassembly gap 30. This side is configured as the inclined surface 40. When the first elastic member is pressed inward, the inclined surface 40 gradually approaches the side wall of the groove 545 until it abuts against the side wall of the groove 545. If the first elastic member is continued to be pressed, the protrusion 145 can slide in the direction of disengaging from the groove 545 under the action of the inclined surface 40, and finally it is easy to disengage the protrusion 145 and the groove 545.

[0046] Specifically in this embodiment, a protrusion 145 is provided on the side of the first free end 143 facing the second free end 543, and a groove 545 cooperating with the protrusion 145 is provided on the second free end 543, and the first connector 10 and the second connector 50 are buckled by the cooperation between the protrusion 145 and the groove 545. It can be understood that in some other embodiments, a protrusion 145 can also be provided on the side of the second free end 543 facing the first free end 143, and a groove 545 cooperating with the protrusion 145 can be provided on the first free end 143, and this is not limited.

[0047] In some embodiments, the first connecting member 10 also includes a guide portion 16 provided on the first body 12, and the second connecting member 50 also includes a limiting portion 56 provided on the second body 52; along the assembly direction of the first connecting member 10 and the second connecting member 50, a limiting groove 561 is provided on the limiting portion 56, and the guide portion 16 is limitedly abutted against the limiting groove 561, so that the second elastic member 54 can be accurately assembled into the mounting hole 121 through the cooperation of the guide portion 16 and the limiting groove 561, guiding the first elastic member 14 and the second elastic member 54 to be accurately and quickly buckled.

[0048] Furthermore, the guide portion 16 is arranged on the inner wall of the mounting hole 121 around the first elastic member 14, and the guide portion 16 and the first body 12 enclose a receiving cavity 20, and the receiving cavity 20 has an opening for allowing the second elastic member 54 to extend therein, and the second elastic member 54 extends thereinto and is detachably engaged with the first elastic member 14. When assembling the first connecting member 10 and the second connecting member 50, the guide portion 16 extends into the limiting groove 561 provided on the limiting portion 56, and the second elastic member 54 extends into the receiving cavity 20 through the opening, and then is detachably engaged with the first elastic member 14. In addition, the guide portion 16 is arranged around the first elastic member 14, so that the second elastic member 54 can be accurately guided to cooperate with the first elastic member 14 through the guide portion 16, thereby improving assembly efficiency and accuracy.

[0049] Furthermore, the guide portion 16 is arranged around the first elastic member 14, and the second elastic member 54 extends into the accommodating cavity 20 between the guide portion 16 and the first elastic member 14 to be detachably engaged with the first elastic member 14, and a deformation gap 60 is reserved between the second elastic member 54 and the guide portion 16. In this way, when the first elastic member 14 is pressed inward, the second elastic member 54 is driven to bend and deform in a direction close to the deformation gap 60, thereby loosening the engagement of the first elastic member 14 and the second elastic member 54, so as to allow the first elastic member 14 and the second elastic member 54 to be deformed and bent inward through the reserved deformation gap 60, thereby facilitating the disassembly of the connection structure 100. In addition, the limiting portion 56 is located on the side of the guide portion 16 facing away from the second elastic member 54, and the limiting portion 56 will not interfere with the mutual interference between the first elastic member 14 and the second elastic member 54.

[0050] Specifically in this embodiment, the guide portion 16 includes a first guide plate 161, which is arranged opposite to the first elastic member 14. The first guide plate 161 is in limiting contact with the inner wall of the limiting groove 561 along a first direction intersecting with the assembly direction of the first elastic member 14. In this way, the guide portion 16 is limited in the first direction through the cooperation between the first guide plate 161 and the limiter, so that the first connecting member 10 and the second connecting member 50 can be aligned in an accurate manner during assembly, which is convenient for quick assembly.

[0051] Furthermore, the guide portion 16 also includes two second guide plates 163 arranged opposite to each other, the first guide plate 161 is connected between the two second guide plates 163, the two second guide plates 163 are located in a second direction intersecting the assembly direction and the first direction, and the second guide plates 163 and the inner wall of the limiting groove 561 are limitedly abutted along the second direction. In this way, two second guide plates 163 are also provided, and through the cooperation between the second guide plates 163 and the limiting groove 561, the guide portion 16 is also limited from the second direction, and the limiting accuracy is further improved. In this way, the relative position between the first connecting member 10 and the second connecting member 50 is limited from both the first direction and the second direction, and the second elastic member 54 can be assembled into the mounting hole 121 at one time, thereby improving the convenience and efficiency of assembly and reducing the cost.

[0052] A fan includes a fan body, a base, a plurality of rods and the above-mentioned connection structure 100. The connection structure 100 is provided between the fan body and the rod, between the plurality of rods, and between the rod and the fan body. The fan body, the plurality of rods and the base are connected to each other through the connection structure 100 to facilitate installation and removal of the fan. It can be understood that the fan body is provided with a first connection member 10 or a second connection member 50, the rod is provided with a corresponding first connection member 10 and a second connection member 50, and the base is also provided with a corresponding first connection member 10 and a second connection member 50. As for whether to specifically provide the first connection member 10 or the second connection member 50, it only needs to be considered that the connection members on the adjacent components can be matched and assembled. As for whether to provide the first connection member 10 or the second connection member 50 on the specific components in the fan, it is not limited here.

[0053] In addition, the plurality of rods may be one rod or multiple rods, and the number of rods may be selectively increased or decreased according to the actual required fan height. The corresponding multiple rods, or the rods and the base and the fan body may be assembled according to the connection structure 100.

[0054] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
